Today the team face some party crashers and also face the danger of the fourth wall.

Landry is hosting a get together at O’Neill’s old cabin for the team with Mitchell managing to arrive on time only to be told that the rest of the team are going to be late for a variety of reasons with Teal’c offworld assisting SG-3 hunt down a creature that’s tearing people limb from limb, Vala and Carter still at the SGC, and Daniel in the UK researching the Ori. Those at the SGC decide to stay longer to sort out the monster issue, with Vala trying to get Teal’c to help sell it on the open market.

SGs 3 and 25 head back offworld with the SGC’s resident aliens Teal’c and Vala to try and find out just what is doing the killing, only for SG-25 to be almost slaughtered in an attack by the creature. When Vala retreats to get backup from the SGC, soon joined by Teal’c who’d been looking for her, she’s attacked by the beast which the pair of them manage to kill.

At the cabin retreat Mitchell is still uncomfortable around Landry, not used to the idea of fraternisation with superior officers off-duty, but begins to open up about his issues with the SGC and his own problems trying to fit in. After they both turn in for the night they almost shoot each other when woken by what they feared was strange noises outside and come morning find themselves stranded due to the bad weather having blocked the way out. Landry decides to fill the time by going bird-watching in the nearby forest while Mitchell goes for a run only to come across a panicked hunter who’d been attacked by a creature and whose friend was killed by it.

Still cutoff from the cabin the rest of SG-1 decide to wait at the SGC and watch the autopsy of the creature they’d killed, only for a giant leech creature to crawl out from it. The autopsy concludes that the actual creature used to be a little marsupial and that the leech likely caused it. Another SG team returns from offworld to find that they’d been attacked by a similar creature on another planet from the first attacks, pinpointing that the cause of the creatures seems to be SGC in origin. Carter is able to pinpoint the source of the leeches to the Sodan Cloaking Device.

At the cabin the road is finally reopened to make way for the police but also unfortunately the makeshift militia of hunters in the area. Mitchell and Landry decide to lend a hand in the woods, with Landry revealing his history of having to evade North Vietnamese troops after being shot down while a pilot. Their stories are cut short however when the creature attacks and kills another hunter. Eventually the hunters are able to catch something, a Trust Operative with the missing Sodan Cloaking Device from Area 51.

The rest of SG-1 head to the cabin after the discovery of the Operative and fears that there’s still a creature on the loose, proved to exist when the Sheriff is mauled to death just outside the cabin. Along with several other SG teams they begin to search the park for the creature. Eventually, in the middle of the night, they manage to kill two creatures who attack the group and believe it’s the end of it. The team finally begin their get together at the cabin, with even Landry joining in a game of poker.

I do like this episode even with its flaws as it does something that the show has largely avoided over the years but have started exploring more over the Ori saga which is that the entire episode situation is caused by the SGC themselves. Most of the time the show is very quick to find some way to blame something for what has happened, a Goa’uld experiment perhaps or maybe rowdy locals. Even the discovery of the Ori is partly the Ancient’s fault given how they didn’t destroy or leave a warning about the Ancient Communications interface. Here however the fault is admitted to be all down to the fault of the SGC, having decided to play around with the Sodan Cloaks simply because they thought they knew better than the Sodan. It’s fun to watch the show admit that maybe intervening all the time has slightly gone to their heads, with the result being that maybe they don’t always know best but sadly think they do (a trap many sci-fi shows have fallen into but never gotten out of).

This placement also works as a good way to explain why an all powerful McGuffin can’t be used by the team to solve lots of problems. The show has recently used “getting destroyed in the very next episode” as a reason to say why something can’t be used again after it saved the day once but this statement that the Cloak is poisonous and even the fix makes it dangerous feels more believable than it either getting blown up or left at Area 51 for all of time. It joins other good McGuffin killers on the show such as the power armbands eventually being seen as a virus and rejected by the body and the recall device blocking use of Goa’uld ships both seen back in season 4.

The episode also serves to give some more depth to Landry as a character. Up until now the new commander of the SGC hasn’t really been explored as a person all that much, with the only real facts we know about him being his love of quoting people and that his daughter is the very rarely seen chief surgeon at the SGC. Now however we see that despite the job he doesn’t particularly enjoy using violence as a result of his experience of being the one hunted in the Vietnam War and that he enjoys relaxing as much as possible in fairly laidback activities outside the office. It’s still a shame however this has come about a season late as by now he’s not really had much airtime compared to previous leaders of the base as they never gave him something to do.

Overall Uninvited is a relatively fun little episode that largely exists to explain away the Sodan Cloaking Device’s non-use by the team. It does however also add much-needed backstory to Landry who has been a blank slate up to now though sadly not enough to give him more depth at this point.

Assorted Musings

· With even the US Army getting an SG team now they missed a trick not having more international ones, like a Royal Marines Commando or French Foreign Legion team.

· That drumbeat when someone other than the commander finally sits in The Chair.

Quote of the episode: “It is ironic that not so long ago the mere presence of a Goa’uld on Earth have been cause for great concern.”

“Seriously who’d ever think that we’d have bigger fish to fry, or that you’d use the word “ironic” in a sentence.”

“Indeed.” – Teal’c and Carter

We begin with the team finally meeting the fourth of the Alliance of Great Races, the Furlings, only for the planet to immediately come under attack from the Goa’uld and be destroyed. It turns out however this is an elaborate opening for the Wormhole X-Treme film, Martin Lloyd’s next big project, and the team have been made “technical advisors” on the thing against their will. Not happy with the current draft the team begin suggesting their own ideas for the show with Mitchell suggesting a zombie apocalypse on the base and Vala ripping off both Wizard of Oz and Farscape while Carter suggests the fun “incident” from their own adventures with the time O’Neill was invisible. Instead Martin continues with his terrible ideas, such as an impossible escape from the Goa’uld (which they don’t even show), ripping off Star Trek, and the mountain itself blowing up.

The episode then shows a pilot for Stargate Universe, a version that’s younger and edgier with lots of sex and gunfire. To pass the time the rest of the team decide to take the mickey out of Mitchell by implying that O’Neill got Mitchell’s mum pregnant during 1969. When Martin returns to reveal that the actors are holding out for better pay they instead suggest he does a Team America version. Soon after O’Neill shows up in a twist everyone saw coming, making time for Teal’c to suggest his own detective show to Martin. It turns out O’Neill has largely showed up because he misses the place (though won’t admit it) but suggests the film ends with the team going fishing. Vala has another shot by suggesting finishing the film with the wedding of a certain leading couple on the show. Before the session can go any further it’s revealed that the Gate is finally repaired, with everyone going to celebrate Mitchell’s 200th trip through the Gate with even Harriman going thereby revealing it’s another fiction. Martin however reveals that Wormhole X-Treme has suddenly been renewed.

To finish we cut to the filming of the 10th season and 200th episode of Wormhole X-Treme, with the cast revealing to the camera some of the concerns over the year where Martin pats himself on the back for writing it, Fake Tapping wanting to direct an episode of the show or have a baby, Fake Shanks glad the writers brought him back after quitting the show didn’t work out for him, and Fake Browder overemphasising his ability to swear so they’d “forget” about Fake RDA. The episode closes out with Fake Judge talking about the importance of Science-Fiction as a genre and quoting Isaac Asimov.

So here we are, the 200th episode and what a brilliant thing to watch. This is definitely one of the things I look forward to every time I watch through the show as it’s just a non-stop love-in of the show’s history and TV Sci-Fi in general. From niche shows like Farscape and Firefly to big shows like Star Trek the whole of the genre ends up getting the piss taken out of it in a fun and friendly way as they point out the glaring holes in common plots and techniques that get taken advantage of by writers.

The way the episode is structured into all these loose vignettes that are just a mix of the insane to downright ridiculous are also a real joy to watch as the characters place their reactions on them, with the overuse of zombies getting redflagged while the idea of just blowing up the base for the awe factor of a trailer also lambasted. The small touches in some of these vignettes make them works of genius to watch again and again, with the puppet strings being removed if you go through the Gate or the teen-schlock dialogue of totally not what Stargate Universe ended up being.

It’s funny how some of the things they do mock ended up being the biggest criticisms of the third Stargate show.

One of the best parts has to be the ending 5 minutes, which doesn’t really have anything to do with Stargate at all really but the show within the show where the “cast” instead just make comments about the cast of the real show in a long series of interviews. Not even the real-world cast are able to avoid the ribbing of the 200th episode with several quite disparaging in any other circumstances judgements about each member of the cast being made such as Michael Shanks’ decision to quit during season 5 getting shown as a failed career move or Amanda Tapping wanting to do more behind the camera being an uncaring decision to sabotage production almost.

Overall this comedic and somewhat self-parodying tone avoids the common pitfall of grand milestone episodes turning into too much of an egorub for the show which can sometimes come across as smug rather than celebratory. I mean what other show would include a scene that was deliberately mocking the fact they referenced a race in a single line in season one and then make the parody opening about them.

In the end the episode is the perfect way to send up 10 years of a beloved show that never took itself too seriously. It’s funny and endearing to watch, especially given how the show was cancelled soon after, as all the cast and crew just have fun with everything they’ve built over the years and that’s what you want this sort of thing to be, fun for everyone.

Apart from Jonas Quinn, he isn’t here.

Assorted Musings

· Dogs driving cars? Now they’ve gone too far!

· I love how they got RDA in to play himself as invisible.

· That terrible film “points in space” drawing.

· The fact that the O’Neill showing up was actually spoilt in the trailer for this episode.

· I still think to this day Teal’c PI should be a real show.


Doping Dependence of Spin Dynamics of Drifting Electrons in GaAs Bulks

We study the effect of the impurity density on lifetimes and relaxation lengths of electron spins in the presence of a static electric field in an n-type GaAs bulk. The transport of electrons and the spin dynamics are simulated by using a semiclassical Monte Carlo approach, which takes into account the intravalley scattering mechanisms of warm electrons in the semiconductor material. Spin relaxation is considered through the D'yakonov-Perel mechanism, which is the dominant mechanism in III-V semiconductors. The evolution of spin polarization is analyzed by computing lifetimes and depolarization lengths as a function of the doping density in the range 1013 ÷ 5 × 1016 cm-3, for different values of the amplitude of the static electric field (0.1 ÷ 1.0 kV/cm). We find an increase of the electron spin lifetime as a function of the doping density, more evident for lattice temperatures lower than 150 K. Moreover, at very low intensities of the driving field, the spin depolarization length shows a nonmonotonic behaviour with the density. At the room temperature, spin lifetimes and depolarization lengths are nearly independent on the doping density. The underlying physics is analyzed.

Heirloom Treasure

I am not sure what year this quilt was made, but I know it was hand-pieced and quilted by my great-grandmother, Emily Joella Pruett Butler and her oldest daughter, Emily Mary Ann Butler.  It is feedsack, and has always been one of my treasures.
 The quilt is lap-size.  I think the size was a determination of just how much material they had right then, because the top is "cut-off" to accommodate the size of the backing which has been curled around from the back to make the border.  It's a shame that some of the front was lost in this way.  One thing I absolutely LOVE about it, are the colors and the way they work with the design.  All of the background triangles are green.  All of the little squares are blue, either light or dark (and just a few pink).  All of the stars are red or pink.  It looks like they were put together randomly, and that makes it all the more interesting.  I know that each woman had to have pieced each square by hand from a basket of cut-out pieces, and then in the end, put it all together.  So, one didn't really pay attention to what the other was doing, necessarily.  The design follows a perfect pattern, but the randomness of the lights and darks is what makes it so much fun!  I adore the bright red against all the light pieces in the one square, and that right next to it is a light star with darker pieces around it.  Two totally different "looks."
 And look very closely at the top left of the folded quilt.  There is a light green triangle that was pieced with a piece of darker green, because I guess they ran out of light green and needed just that tiny little bit more of the green to make that triangle!

This quilt is proudly displayed in my living room on a quilt stand given to me one Christmas about eight years ago.  I used to have the quilt across the back of my couch when my daughter was small, but it's been protected in a pillow case since then, waiting for a chance to display it again.

Intercountry adoption declines lead to new practices of global surrogacy in Guatemala: Global human rights concerns in the context of violence and the era of advanced fertility technology.
Rotabi, K.S. and Bromfield, N.F.
Karen Rotabi

Intercountry adoption has declined significantly in the last five years. It is not as feasible an option anymore for building a family with a very young child or infant from Guatemala.. However, global surrogacy appears to be meeting the need for some individuals and couples. Contracting surrogacy with a woman in another nation is explored, focusing on vulnerable women. Specifically, surrogacy in India and Guatemala is discussed with concerns about informed consent in the context of poverty and, in the case of Guatemala, violence against women and human trafficking. Technological advances and globalization are also considered asthe authors pose critical questions about the practice of global surrogacy. Implications for socialworkers and human rights defenders are also posed, underscoring the importance of awareness to this emergent global practice.

Asked and Answered: Jan. 12

Posted Jan 12, 2016

Let’s get to it:

So pumped up after that bizarre playoff win. Here is my question: What does it take to eject a player from an NFL game? Yes, Vontaze Burfict and Pacman Jones came to mind when I thought of this question.

Like so many other things regarding the NFL rulebook, I don’t know that there’s a definitive answer for that. There was some belief within the Steelers organization that the officials for the Wild Card game last Saturday were going to be much more amenable to ejecting players for both between-the-whistles misconduct as well as the post-play garbage that was too much a part of the regular season game at Paul Brown Stadium. Currently, there is some disagreement within the NFL about whether the best method of handling some of this stuff is to penalize it and then eject players during the game, or whether it’s better to penalize it and then come back with fines and suspensions in the immediate aftermath. Maybe some consensus is reached over the course of the upcoming offseason, but until then I have no answers for you.

The Steelers defense got a flag for delay of game. I've seen it before in hurry-up situations for the opposing offense, but this wasn't the case. Can you explain it?

I’m going to give it a shot, and I believe the situation to which you refer involved James Harrison. When the clock is running, and when the defense crosses into the neutral zone and induces movement along the offensive line, the penalty called can be referred to as delay of game on the defense.

Are you aware of any precedence for the NFL to suspend a player from playing a specific team the following season?

No. Suspensions are levied based on the number of games, as opposed to removing a player from a game against a specific opponent. So cynical am I that when it was announced on Monday night the NFL had suspended Vontaze Burfict for the first three games of the 2016 NFL season, my immediate thought was that the league would schedule Bengals vs. Steelers for Week 4. And don’t be surprised if it’s a primetime game, too. Anything for TV ratings.

Just a couple of quick questions about rules enforcement in the wake of the Wild Card Round game in Cincinnati: If the touchdown by William Gay was taken off the board, why was the penalty of excessive celebration not taken off with it? Especially since one was the direct result of the other. And after the Vontaze Burfict interception, he took the ball, and with several teammates, ran off the field and up the tunnel. How was that not a penalty for excessive celebration, delay of game, celebration involving teammates, something?

As to your first question, an unsportsmanlike conduct penalty – which is what excessive celebration is – takes precedence over whatever else might have happened or been nullified during or after the play in question. So even though William Gay didn’t score a touchdown officially, there still could be a penalty for excessive celebration. Why Burfict and his entourage also weren’t penalized for excessive celebration is a complete mystery for me. I have nothing for you on that one. Should’ve been a flag.

In my opinion, Ryan Shazier was the defensive MVP of the game against the Bengals. Some bitter Cincinnati fans are saying his hit on Giovani Bernard was as bad as Vontaze Burfict's hit on Antonio Brown, but during the broadcast, it was made clear that Shazier's hit was legal, and I would like to think it happened without the intent to injure, as Burfict's was. My question is, since it was a legal hit and Shazier recovered the football, was it not a major officiating blunder that the play was whistled dead? In my mind, had his fumble return for a touchdown counted, the Steelers would have had a more comfortable lead and perhaps all the insanity that took place later would not have happened.

Because I was at the game, I was not aware of what was said on CBS’ broadcast of the game, so I cannot comment on that. After watching the replay many, many times, the way I saw the play was that Giovani Bernard was not a defenseless player, because he had possession of the ball and had become a runner. To me, the issue was whether Ryan Shazier led with the crown of his helmet, but since no penalty flag was thrown at the time the issue will be adjudicated at the league office, which means a fine would result if it’s determined Shazier did lead with the crown of his helmet.

But back to the game. Since no penalty flag was thrown, I saw the play as a fumble, and a recovery. There also was no down-by-contact, and so the return should have been permitted. But because of the way the play originally was whistled dead, the officials weren’t going to reverse themselves on a challenge and award a touchdown to the visiting team, even though that would’ve been the correct call. That’s just my opinion. In instances where the on-field officials end up relying on replay, there also is the possibility that someone in “command central” in New York is “helping” with the call and the interpretation of same. I have absolutely no evidence or knowledge of this, but I believe the decision was made to “split the baby,” so to speak, which in this case involved giving the ball to the Steelers – as it should have been – but not awarding the touchdown that should have followed, because that would have given the Steelers a 22-0 lead at the end of the third quarter and effectively ended the game. Again in my opinion, NFL officials will legislate the game to keep the score close, and that’s how this ruling came about.

No question but just wanted to say that VERY excited about facing Denver this weekend and am so proud that this team faced the hardest schedule in the league, battled some serious injuries the whole season, but the players and coaches never quit and got the job done. Great character, and I just wanted to say thanks.

Consider it done.

Luminosity Changes

With only seventy-four days until I leave for MDRS, the crew and I have been gradually learning about each other and figuring out what exactly we’ll be doing. Thankfully, because I’m a little anal and will be buried in work in a few weeks, I’ve been refining my own ideas over the past few days. It’s also necessary for a few sponsorships that some of my crewmates are trying to get, so having what we’ll actually be doing out in the desert written down helps us get money and plan everything out. I’ve also written a bio about myself for the crew website and the MDRS website, but that’s not up yet… So, let’s get on to the research!

Synopsis: A subset of three to seven Algol (EA/SD) variable stars will be observed using the Musk Observatory 0.36m telescope and CCD camera. The stars will be observed while watching for the two luminosity dips during one complete period, which will be measured and analyzed to extrapolate physical characteristics of the dimmer companion. Two exoplanet transits (HD 209458 and TYC 1987-1212-1) will also be observed in a similar fashion, but in the case of TYC 1987-1212-1 those observations will be to either confirm or deny the existence of the exoplanet. These projects will give a good indicator of what research can be completed on the planet Mars, and at MDRS, in future missions.

Description: Algol-type (EA/SD, eclipsing binary) stars are binary systems where the dimmer companion passes within the line of sight of the observer by moving in front of the brighter companion. This leads to a cyclic drop in luminosity twice during the entire orbit: once when the dim star is in front of the bright one and once when the dim star is behind the bright one. During the two times of occultation, the luminosity is for the most part constant once the dim companion is completely in front of or behind the brighter star, as viewed from our solar system.

The periodic luminosity changes of seven EA/SD Algol stars, with three (TX CMa, R CMa, and AK CMi) being the primary targets of the study, will be analyzed from the Musk Mars Desert Observatory (Musk) at the Mars Desert Research Station (MDRS) near Hanksville, Utah. By observing the luminosity changes and the duration of the minima, the size and orbital separation of the stars, thereby refining the observed measurements of the variable stars.

Similarly, the current search for exoplanets involves observing planetary transits, such as the current Kepler mission. The basic premise for observation is the same: observe the target star to watch for luminosity changes due to the transiting planet. Two such targets will be analyzed, the parent stars being HD 209458 and TYC 1987-1212-1. The first star is a known exoplanet, so the observations would center on refining the measurements already obtained. As for TYC 1987-1212-1, the transiting exoplanet has not been verified, so observing these transits would either confirm or deny the existence of that planet.

Both of these experiments rely upon careful calibration of the equipment, long observing sessions, and careful analysis of the data. Due to the non-linearity of the luminosity changes, these observational targets are tough to observe, especially with periods of inclement weather poor observational conditions, and other weather-related variables. Such conditions, however, would be frequent on Mars, so a successful data set would verify that such research could be performed on the surface, as well as other less fickle projects.

摘要: The GaN epilayers are grown on (0 0 1)GaP substrates by low-pressure metalorganic vapor-phase epitaxy using the three-step growth method, which includes the growth of the GaN buffer, interlayer and high-temperature epilayer. From atomic force microscopy examinations, it is indicated that the surface roughness of the GaN buffer layer grown at 515 degreesC increases drastically with increasing the annealing temperature from 700 degreesC to 850 degreesC. The thickness and growth temperature of the GaN interlayer were optimized based on the X-ray and morphology measurements. It was found that a 0.2-mum-thick GaN interlayer grown at 750 degreesC can efficiently restrict the desorption of P atoms from the GaP surface, which is an essential step for the subsequent growth at high temperature (900 degreesC). Furthermore, as the epilayer thickness increased, the GaN surface became rougher due to the increase in the composition of the hexagonal component. The 77 K photoluminescence spectrum of the mirror GaN epilayer (0.6 mum in thickness) exhibits a near-band-edge emission peak at 3.36 eV as well as a yellow emission at 2.29 eV. The corresponding electron mobility and carrier concentration at 300 K were 15 cm(2)/Vs and 6.7 x 10(18) cm (-3), respectively. (C) 2000 Elsevier Science B.V. All rights reserved.

Abstract: This research relates to image reading in kindergarten, presenting as theoretical referential the contributions by Vygotsky, Sarmento, Schultz-Foerster, Araujo and others. It is characterized as empirical research, using the qualitative approach, with data collected through semi-structured interviews, oral narratives and imagery of children, photographs and footage of the activities undertaken at school and beyond. It emphasizes the importance of educational practices in the exhibition spaces and the unveiling of the imagination, having children, the arts teacher, trainers and teachers / educators as subjects of teaching and learning process. The objective is to analyze the imaginary drawings of palaces built by children from the kindergarten, in order to understand how speeches may be mediated by pictorial images of the city. Soon, they realized that, through drawings / pictorial records, reassembled scenes from his imagination through the concept of the palace and created others (own) after the visit / tour of the city. Thus, children represent their own views of the world, as heard and seen

"It was during the Aryan inhabitation in the region that epics of Mahabharata, Ramayana, Brahmanas and Puranas were written."

The history of Uttar Pradesh is very much associated with the broad history of India. It dates back to 4000 years. Formerly the area of Uttar Pradesh was occupied by Aryans or the Dasas and their main occupation was agriculture. The Aryans through conquests occupied the adjoining areas.

They laid the foundations of its civilisation in the region. It was during the Aryan inhabitation in the region that epics of Mahabharata, Ramayana, Brahmanas and Puranas were written.

The state was the heart of Mahabharata war. The Kosala Kingdom of Ayodhya is said to have been incarnated in the city of Mathura.

It was sometime around the middle of the 1st millennium BC that Uttar Pradesh saw the advent of Lord Buddha and the spread of Buddhism. Around the time Lord Buddhadelivered his first sermon at Dhamek Stupa in Sarnath, Uttar Pradesh was under the Magadh rule. The Chaukhandi Stupa here marks the spot where Lord Buddha met his disciples.

Besides Kuru, Panchalas, Vatsas, and Videhas etc. formed the early region of the state. These regions were known as Madhyadesa. During Ashoka`s role, several public welfare works was taken up. During the rule of Magadha Empire, Buddhism and Jainism developed in this region. It was a period of administrative and economic advancement.

" In due course of time, Uttar Pradesh witnessed the decadence  of Mughal rule and advent of the British. The Mughal influence was restricted to the Doab region."

The power subsequently shifted to the Nanda dynasty and then to the Mauryas. The region reached its pinnacle of glory during the reign of Harshavardhana.

The historical background of Uttar Pradesh has a lot to do with the advent of Muslim rule. This period witnessed the subjugation of the Rajputs whose power was confined to a few pockets of Rajasthan. Uttar Pradesh reached the peak of prosperity during the Mughal rule, and particularly during the rule of Emperor Akbar.

The British East India Company came into contact with rulers of Awadh during the reign of third Nawab of Awadh. There is no doubt that the history of Uttar Pradesh has run concurrently with the history of the country during and after the British rule, but it is also well-known that the contribution of the people of the state in the national freedom movement had been significant. Uttar Pradesh also played a key role in the 1857 War of Independence.

From the rule of Rama to the rule of British, Uttar Pradesh has seen it all.

Useful Tutorial on how to Write a Literary Analysis Thesis

First, Write Your Thesis Statement

  • The thesis statement is comprised of one or two sentences where you state an argument.  It is in the form of your opinion, where you are presenting a side of an argument.  You will persuade the reader to agree with your statement.
  • Take time in writing your thesis statement.  Your thesis statement is the main topic of the paper.  A well thought out and good thesis statement almost always allows the whole paper to write itself.  It’s concise, clear, and gives direction to the whole paper.
  • Use action verbs when writing your thesis statement.  Using action verbs is a trick in great thesis statement writing.  Action verbs help persuade the reader, because you are calling the reader to action.

Two, Write Your Introduction

  • The introduction is a summary of what the body of your thesis will be about.  The introduction also includes the thesis statement.
  • Incorporate your thesis statement at the end of your introduction.  Contrary to what one may think, a good introduction concludes with the thesis statement.  This is better for the reader, because the reader is first
  • introduced to the general body of the paper.  The reader gains general background information first which allows the reader to better understand the thesis statement and how he or she is being called to action.

Next, Write the Body of the Paper

  • The body of the paper is where you will be supporting your thesis statement with examples, supporting evidence from the literature.
  • The body of the literary analysis may also include researched evidence from outside the literature piece.

Then, Write Your Conclusion

  • The conclusion summarizes the supporting evidence (body of the paper) and then circles back to the original thesis statement.
  • A good conclusion ends with a “cincher.” A cincher is similar to the thesis statement.  However, now, you write it with a more factual tone instead of presenting an opinion.  You can do this because you have given the reader supporting evidence.  You win the argument, so to speak.

Finding the gap in the defense is the goal of the offense. The quarterback and his players run, pass and move down the field to finally enter the end zone of the opposing team: Touchdown! Hackers use a strategy similar to that of a football team in attacking the opposing side. And in the end, they, too, often win.

By Katrin Pudenz

Hackers detect the gap and sneak their way into a company’s or plant’s software system. In consequence, the company loses reputation, money, knowledge, security and safety. This is why VDMA and Steffen Zimmermann, VDMA Informatics, Managing Director Product and Know-how Protection, push hard for cyber security. Zimmermann pleads for a stronger focus on security.

“Currently, if we discover deficits in security, we usually apply a patch,” he explains. “Just like putting a Band-Aid on a bleeding wound.” And this needs to be changed. “Greater focus must be placed on security.” Zimmermann points to the European Machinery Directive: This directive specifies the must-haves for machines in the production process and commissioning period, but there are no further specifications concerning the everyday operation under realistic conditions. “At first, machines and plants are secure. But after being put into service, the security level drops continuously. The reason: there is no further development of security. The attackers sharpen their skills constantly. And if they find any new gaps, they will attack.”

An infiltrating worm

What happens when malware strikes is best exemplified by the well-known example of Stuxnet, a malicious computer worm. Stuxnet apparently was a cyber weapon intended to sabotage Iran’s nuclear program. Stuxnet targets programmable logic controllers (PLCs). These controllers allow the automation of electromechanical processes. For example, controllers used to control machinery on factory assembly lines or even centrifuges for separating nuclear material. Stuxnet targets machines using the Microsoft Windows operating system and networks and then seeks out Siemens Step7 software. This malicious computer worm reportedly compromised Iranian PLCs by collecting information on industrial systems and causing the fast-spinning centrifuges to collapse.

Hackers collect information

“This is an example for what hackers are able to do,” explains Steffen Zimmermann. They can access a system and do whatever they aim on doing; hackers need to collect as much information on the specific product or system as possible. Often the products or systems are unknown territory, so-called black boxes, to the hacker. So for them, it is essential to obtain detailed information on the interfaces, for example, which software is being used and how to enter the system, and/or how to attack it. The security gap might be an employer or they might find their way via an unsecured Internet connection. “Most of the attacks are carried out through the Internet,” the VDMA cyber security expert explains. According to a study on product piracy, information searches are conducted via reverse engineering (72 percent), misappropriation of know-how (42 percent), disclosure statements (18 percent), industrial espionage (15 percent), robbery, theft and extortion (1 percent). Reverse engineering, or back engineering, is the process of extracting knowledge or design information and reproducing it or other products or ideas based on the extracted information. If reverse engineering is used to crack software or remove a copy protection, it is being used in a harmful way. Creating a cheap copy could be the goal of a competitor.

Targets and protection goals

Hackers have specific targets such as classified information. In turn, security specialists have targets they want to protect from attackers: i.e. specific software, a method, production process, formula and, of course, the reliability of a developer, system or company. If product designers want their products to be safe and secure, they always need to evaluate what an attacker could possibly want and what the motivation for the attack could be. “If the reason involves counterfeiting or plagiarizing merchandise, the motivation obviously is profit maximization,” Zimmermann points out. “If the goal is to sabotage a system, the reason for the attack is to discredit the company.” Therefore, products need to be trustworthy, upright, reliable, and authentic.

“An attack can be,” as Zimmermann cites ICS-Cert, “unauthorized access and exploitation of Internet facing ICS/Supervisory Control and Data Acquisition (SCADA) devices, an exploitation of zero-day vulnerabilities in control systems devices and software, malware infections within air-gapped control system networks, SQL injection via exploitation of web application vulnerabilities, network scanning and probing, lateral movement between network zones, targeted spear-phishing campaigns, and strategic web site compromises (a.k.a. watering hole attacks).” This all sounds quite cryptic and theoretical, admits the VDMA-expert. But in the end, all these different kinds of attacks lead to considerable harm, destruction and, ultimately, a loss of money.

How to protect successfully?

Today, we are still living in a largely non-digitized industrial world, Zimmermann emphasizes, even if this is somehow hard to believe. But with the upcoming age of Industrie 4.0, everything will be digitized and connected: humans and machines, machines and machines, machines and humans, humans and humans. Therefore, we will soon no longer need security for business processes only; we will also need security for manufacturing processes and products. And the users need to be sensitized.

Think security

“In the mechanical engineering business, engineers design and build features demanded by customers. Security in plants, machines etc. is generally neglected since there is no real demand for it,” the expert explains. But security needs to be integrated into the infrastructure of every machine, every plant, and every single product. “This is what we are fighting for, and this is what the German and European governments are working on,” says Zimmermann. The German parliament passed a new IT-security law, but this law can only provide a framework for persuading companies to deal with security and establish appropriate structures. Zimmermann amends, “We need to make sure that laws do not restrict innovations. Industrie 4.0 production is designed to be secure; now we need to make sure that the products will be as well.” This is what the IUNO project – a project VDMA supports – is working on: researchers plan to demonstrate, by means of specific use cases, how to minimize the points of attack. For instance, they want to investigate how to safeguard the production process against cyber threats.

How to safeguard products and machines

“To ensure this, security by design is not only the trend, it is the solution,” Steffen Zimmermann emphasizes. “In the long term, we need to accomplish security by design and security as a function. Security by design means that we need to examine the entire process: from the design up to the end of the products’ life cycle. Security needs to be implemented right from the beginning.”

Dr. Eric Maiser, head of the VDMA Competence Center Future Business, adds another method for security by design to the list: “Hardware encryption is another important aspect of viable security concepts. The difference between software and hardware security can be illustrated by how you secure the front door of your house against unwanted entry: Somebody rings and you ask for a password. If the password is correct, you let him in. That is the software-type of entry. The hardware part is to have a lock on the door and the person who wants to enter needs a physical key. Although you can fake both, it is a lot easier and less expensive to obtain the password than duplicate the key. Combining both methods is more effective than just upgrading one of them. Having neither a password nor a lock nor a door is not very wise – still, this is exactly the status of a tremendous number of applications.”

Hardware security systems

Hardware encryption is an electronic variation to mechanical locks when it comes to controlling data streams. This is done by so-called gateway systems that need to be certified. Comparable to drilling the mechanical lock open or to duplicate the key, one would need to physically manipulate the encryption chip to achieve unauthorized access. “Of course, the effort for hardware security systems and their certification has to be justified and adopted to the respective situation. It does not make sense to have a security chip in every single part of the ‘Internet of Things’, for example a toaster or refrigerator,” Maiser says. “However, critical infrastructures such as utilities, factories or machines require the best security you can possibly get. And that includes providing hardware and software security at the same time.”

If this is not possible because a hardware gateway is blocking the entrance, the hacker will have to physically enter the factory. And this is an option most hackers hardly will choose. Hardware security gateways are already in place, for example, in credit card terminals and smart meters. Official and trusted certification bodies, standards and chip and electronic equipment makers play a big role here. Cyber security is a particularly vital part of Industrie 4.0. “Technical solutions are available so there is no need to be afraid of implementing Industrie 4.0. We believe there is even new business behind this for the machine manufacturers, plus a new way to fight counterfeit machines and parts. VDMA’s role is making the companies aware of all aspects of this and bringing all relevant parties together,” Maiser points out.

Adopted software and hardware security

The bottom line is that the machinery and production equipment industry needs global legislation on cyber security, secure identities and automated product-machine communication, physical identities for products, parts and human beings as well as embedded security and know-how-protection, Zimmermann demands. “And maybe we should think about CE security guidelines for machines and factories, cars and critical products.”

Everything must be considered: Adopted software and hardware security is the kind of security we need for the future, Zimmermann and Maiser emphasize in complete agreement. “This is what we need for self-driving cars as well as for Industrie 4.0 in production.”

Reflection 19 February 2015

Deuteronomy 30:15 -20 & Luke 9:22-25

Choose life…

We often hear the saying: “Life is all about choices”, and indeed it is. Yet do we really consider the choices that we make? It is also true that the choices we make today have eternal consequences for ourselves and for others.” This should cause us to sit up and pay more attention to the choices that we make – even those that we consider to be small choices.

Lent is an appropriate time to examine our choices. Why do I do the things I do? Why do I say the things I say? Why do I think or feel the way that I do? Are my thoughts, my words, my actions and my feelings life-giving, to both myself and others?

Recall the words of Moses in today’s Reading… “I set before you life and death, blessing and curse; therefore choose life, that you AND your descendants may live.”

Jesus in the gospel, also invites us to examine our choices. He poses the question: “For what does it profit a man if he gains the whole world and loses or forfeits himself”. Am I choosing in such a way that I may be gaining many things… material goods, friends, fame; YET in the process I am losing myself, my family, and maybe even my faith.

Practical Suggestion:

Examine the choices that you have made recently, have they been life-giving? Have they led you closer to your family, have they led you closer to God.

Lord God, I thank you for the many opportunities that come to me each day. Help me to choose in a way that is pleasing to You and life-giving to others. Amen

Title: Modeling the effects of inhomogeneous aerosols on the hot Jupiter Kepler-7b's atmospheric circulation
Comments: Accepted to ApJ
Subjects: Earth and Planetary Astrophysics (astro-ph.EP)

Motivated by the observational evidence of inhomogeneous clouds in exoplanetary atmospheres, we investigate how proposed simple cloud distributions can affect atmospheric circulations and infrared emission. We simulated temperatures and winds for the hot Jupiter Kepler-7b using a three-dimensional atmospheric circulation model that included a simplified aerosol radiative transfer model. We prescribed fixed cloud distributions and scattering properties based on results previously inferred from Kepler-7b optical phase curves, including inhomogeneous aerosols centered along the western terminator and hypothetical cases in which aerosols additionally extended across much of the planet's night side. In all cases, a strong jet capable of advecting aerosols from a cooler nightside to dayside was found to persist, but only at the equator. Colder temperatures at mid- and polar-latitudes might permit aerosol to form on the dayside without the need for advection. By altering the deposition and redistribution of heat, aerosols along the western terminator produced an asymmetric heating that effectively shifts the hottest spot further east of the sub-stellar point than expected for a uniform distribution. The addition of opaque high clouds on the nightside can partly mitigate this enhanced shift by retaining heat that contributes to warming west of the hotspot. These expected differences in infrared phase curves could place constraints on proposed cloud distributions and their infrared opacities for brighter hot Jupiters.

Title: High-resolution Imaging of Transiting Extrasolar Planetary systems (HITEP). II. Lucky Imaging results from 2015 and 2016
Comments: 32 pages, 14 figures, 12 tables. The contents of online-only tables 9 and 10 are included in the arXiv source

The formation and dynamical history of hot Jupiters is currently debated, with wide stellar binaries having been suggested as a potential formation pathway. Additionally, contaminating light from both binary companions and unassociated stars can significantly bias the results of planet characterisation studies, but can be corrected for if the properties of the contaminating star are known. We search for binary companions to known transiting exoplanet host stars, in order to determine the multiplicity properties of hot Jupiter host stars. We also characterise unassociated stars along the line of sight, allowing photometric and spectroscopic observations of the planetary system to be corrected for contaminating light. We analyse lucky imaging observations of 97 Southern hemisphere exoplanet host stars, using the Two Colour Instrument on the Danish 1.54m telescope. For each detected companion star, we determine flux ratios relative to the planet host star in two passbands, and measure the relative position of the companion. The probability of each companion being physically associated was determined using our two-colour photometry. A catalogue of close companion stars is presented, including flux ratios, position measurements, and estimated companion star temperature. For companions that are potential binary companions, we review archival and catalogue data for further evidence. For WASP-77AB and WASP-85AB, we combine our data with historical measurements to determine the binary orbits, showing them to be moderately eccentric and inclined to the line of sight and planetary orbital axis. Combining our survey with the similar Friends of Hot Jupiters survey, we conclude that known hot Jupiter host stars show a deficit of high mass stellar companions compared to the field star population; however, this may be a result of the biases in detection and target selection by ground-based surveys.

Title: Combining angular differential imaging and accurate polarimetry with SPHERE/IRDIS to characterize young giant exoplanets
Comments: 16 pages, 8 figures, 2 tables
Journal-ref: Techniques and Instrumentation for Detection of Exoplanets VIII, Proc. of SPIE Vol. 10400, 1040015 (2017)

Young giant exoplanets emit infrared radiation that can be linearly polarized up to several percent. This linear polarization can trace: 1) the presence of atmospheric cloud and haze layers, 2) spatial structure, e.g. cloud bands and rotational flattening, 3) the spin axis orientation and 4) particle sizes and cloud top pressure. We introduce a novel high-contrast imaging scheme that combines angular differential imaging (ADI) and accurate near-infrared polarimetry to characterize self-luminous giant exoplanets. We implemented this technique at VLT/SPHERE-IRDIS and developed the corresponding observing strategies, the polarization calibration and the data-reduction approaches. By combining ADI and polarimetry we can characterize planets that can be directly imaged with a very high signal-to-noise ratio. We use the IRDIS pupil-tracking mode and combine ADI and principal component analysis to reduce speckle noise. We take advantage of IRDIS' dual-beam polarimetric mode to eliminate differential effects that severely limit the polarimetric sensitivity (flat-fielding errors, differential aberrations and seeing), and thus further suppress speckle noise. To correct for instrumental polarization effects, we apply a detailed Mueller matrix model that describes the telescope and instrument and that has an absolute polarimetric accuracy $\leq0.1\%$. Using this technique we have observed the planets of HR 8799 and the (sub-stellar) companion PZ Tel B. Unfortunately, we do not detect a polarization signal in a first analysis. We estimate preliminary $1\sigma$ upper limits on the degree of linear polarization of $\sim1\%$ and $\sim0.1\%$ for the planets of HR 8799 and PZ Tel B, respectively. The achieved sub-percent sensitivity and accuracy show that our technique has great promise for characterizing exoplanets through direct-imaging polarimetry.

Title: The terrestrial late veneer from core disruption of a lunar-sized impactor
Comments: Accepted for publication in Earth and Planetary Science Letters, 17 pages, 4 figures
Subjects: Earth and Planetary Astrophysics (astro-ph.EP)

Overabundances in highly siderophile elements (HSEs) of Earth's mantle can be explained by conveyance from a singular, immense (3000 km in a diameter) "Late Veneer" impactor of chondritic composition, subsequent to lunar formation and terrestrial core-closure. Such rocky objects of approximately lunar mass (about 0.01 M_E) ought to be differentiated, such that nearly all of their HSE payload is sequestered into iron cores. Here, we analyze the mechanical and chemical fate of the core of such a Late Veneer impactor, and trace how its HSEs are suspended - and thus pollute - the mantle. For the statistically most-likely oblique collision (about 45degree), the impactor's core elongates and thereafter disintegrates into a metallic hail of small particles (about 10 m). Some strike the orbiting Moon as sesquinary impactors, but most re-accrete to Earth as secondaries with further fragmentation. We show that a single oblique impactor provides an adequate amount of HSEs to the primordial terrestrial silicate reservoirs via oxidation of (<m-sized) metal particles with a hydrous, pre-impact, early Hadean Earth.

Title: The Saturnian Kilometric Radiation before the Cassini Grand Finale
Authors: Laurent Lamy
Comments: Refereed article; Proceedings of the 8th International Workshop on Planetary, Solar and Heliospheric Radio Emissions (PRE VIII), Seggauberg, Austria, Oct. 25-27, 2016
Subjects: Earth and Planetary Astrophysics (astro-ph.EP)

The Saturnian Kilometric Radiation (SKR) is radiated from the auroral regions surrounding the kronian magnetic poles, above the ionosphere up to a few planetary radii. It directly compares to the auroral radio emissions emanating from other planetary magnetospheres such as the Earth and the giant planets. Our knowledge on SKR relied on remote observations of Voyager (flybys in 1980 and 1981) and Ulysses (distant observations in the 1990s) until Cassini started to orbit Saturn in 2004. Since then, it has been routinely observed from a large set of remote locations, but also in situ for the first time at a planet other than Earth. This article reviews the state of the art of SKR average remote properties, the first insights brought by in situ passes within its source region, together with some remaining questions before the Cassini Grand Finale and its close-in polar orbits.

Title: Stellar Coronal and Wind Models: Impact on Exoplanets
Authors: A. A. Vidotto (Trinity College Dublin)
Comments: Chapter published in the "Handbook of Exoplanets", Editors in Chief: Juan Antonio Belmonte and Hans Deeg, Section Editor: Nuccio Lanza. Springer Reference Works

Surface magnetism is believed to be the main driver of coronal heating and stellar wind acceleration. Coronae are believed to be formed by plasma confined in closed magnetic coronal loops of the stars, with winds mainly originating in open magnetic field line regions. In this Chapter, we review some basic properties of stellar coronae and winds and present some existing models. In the last part of this Chapter, we discuss the effects of coronal winds on exoplanets.

Title: Molecular abundances and C/O ratios in chemically evolving planet-forming disk midplanes
Comments: Accepted by A&A. 18
Subjects: Earth and Planetary Astrophysics (astro-ph.EP)

(Abridged) Exoplanet atmospheres are thought be built up from accretion of gas as well as pebbles and planetesimals in the midplanes of planet-forming disks. The chemical composition of this material is usually assumed to be unchanged during the disk lifetime. However, chemistry can alter the relative abundances of molecules in this planet-building material. To assess the impact of disk chemistry during the era of planet formation, an extensive kinetic chemistry gas-grain reaction network is utilised to evolve the abundances of chemical species over time. Given a high level of ionisation, chemical evolution in protoplanetary disk midplanes becomes significant after a few times $10^{5}$ yrs, and is still ongoing by 7 Myr between the H$_{2}$O and the O$_{2}$ icelines. Importantly, the changes in the abundances of the major elemental carbon and oxygen-bearing molecules imply that the traditional "stepfunction" for the C/O ratios in gas and ice in the disk midplane (as defined by sharp changes at icelines of H$_{2}$O, CO$_{2}$ and CO) evolves over time, and cannot be assumed fixed. In addition, at lower temperatures (< 29 K), gaseous CO colliding with the grains gets converted into CO$_{2}$ and other more complex ices, lowering the CO gas abundance between the O$_{2}$ and CO thermal icelines. This effect can mimic a CO iceline at a higher temperature than suggested by its binding energy. Chemistry in the disk midplane is ionisation-driven, and evolves over time. In order to reliably predict the atmospheric compositions of forming planets, as well as to relate observed atmospheric C/O ratios of exoplanets to where and how the atmospheres have formed in a disk midplane, chemical evolution needs to be considered and implemented into planet formation models.

Title: GALARIO: a GPU Accelerated Library for Analysing Radio Interferometer Observations
Comments: 13 pages, 9 figures. Submitted to MNRAS. Code at this https URL and documentation at this https URL

We present GALARIO, a computational library that exploits the power of modern graphical processing units (GPUs) to accelerate the analysis of observations from radio interferometers like ALMA or Jansky VLA. GALARIO speeds up the computation of synthetic visibilities from a generic 2D model image or a radial brightness profile (for axisymmetric sources). On a GPU, GALARIO is 150 faster than standard Python and 10 times faster than serial C++ code on a CPU. Highly modular, easy to use and to adopt in existing code, GALARIO comes as two compiled libraries, one for Nvidia GPUs and one for multicore CPUs, where both have the same functions with identical interfaces. GALARIO comes with Python bindings but can also be directly used in C or C++. The versatility and the speed of GALARIO open new analysis pathways that otherwise would be prohibitively time consuming, e.g. fitting high resolution observations of large number of objects, or entire spectral cubes of molecular gas emission. It is a general tool that can be applied to any field that uses radio interferometer observations. The source code is available online at https://github.com/mtazzari/galario under the open source GNU Lesser General Public License v3.

Diversity & Inclusion

Challenges Among Us

The goal of these events is to create a space to talk about what makes medical school difficult and provide an opportunity for students to be vulnerable with each other.

Dinner with Acquaintances

Dinner with Acquaintances is a series of interclass potlucks with 6-7 people in attendance at each. By fostering a greater sense of shared experience, students organically feel closer to their classmates and become more willing to seek and provide support.

Healer’s Art

Developed by Rachel Naomi Remen, MD (Kitchen Table Wisdom, My Grandfather's Blessings), the Healer’s Art I and II electives are process-based courses which explore humanism in medicine using interactive and contemplative approaches. Healer’s Art I and II are offered in the spring covering topics such as “Meaning and Medicine” and “Service as a Way of Life.” Enrollment is limited to ensure an optimal experience for all participants. If you'd like to know more, please contact Dr. Carol Chou at cchou@mail.med.upenn.edu.

Mindfulness Training

Offered each spring, the Mind-Body Medicine and Mindfulness Meditation elective provides a comprehensive overview of mindfulness-based stress management and mindfulness meditation. Students are taught mindfulness as a tool to cope with the demands of medical training while also maintaining connection to the human side of patient care. Participants receive extensive training in several mindfulness-based meditation practices and are taught to use mindfulness to enrich communication, facilitate learning, improve patient care, and enhance relationships. Students develop a powerful set of meditation-based tools that they can adapt to meet their own personal and professional goals.

MS1 Hiking Trip

In May, first-year students leave the soothing comforts of their study spaces for a 3-day backpacking trip in the woods of the Delaware Water Gap in NJ. Students hike in small groups designed to connect classmates who do not know each other well. The trip allows MS1s to deepen their connections within the Penn Med community as well as provide a space for personal reflection, growth, and recuperation. Students interested in this effort should contact PDI.

Yoga Classes

Penn Med Yoga provides free yoga classes twice each week for students to develop physical, mental and spiritual disciplines for personal growth.


Are You at Risk for Glaucoma?

A Yearly Eye Exam will detect Glaucoma

When it comes to Glaucoma, early detection and treatment can result in better outcomes.  If you are unsure whether you are at risk, here are some facts that can help you detect the early signs of Glaucoma.

Glaucoma is one of the leading causes of blindness in the United States. Glaucoma is also not just one eye disease, but a combination of abnormal eye pressures and conditions that damages the optic nerve.

Because the loss of vision is gradual, most people don’t realize they are losing their sight until the disease has advanced further along. That’s why Glaucoma is called the Silent Thief of Sight. The most common type of glaucoma is Primary Open-Angle Glaucoma.

Early detection is crucial to fighting Glaucoma. This is the reason why the Palm Beach Eye Centers highly recommend a regular annual eye exam at any of our convenient locations. Early diagnosis and treatment can dramatically reduce and, in some cases, prevent optic nerve damage.  A simple screening can make the difference between a bright future and a dark one. It’s important to understand that vision lost cannot be regained.

Please contact your local Palm Beach Eye Centers and have one of their trained professionals answer any questions you may have about Glaucoma or other eye related diseases.


E-poster Presentation 2014 World Cancer Congress

Predicting fear of cancer recurrence in gynaecological cancer survivors (#1002)

Jane Hughes 1 , Hayley Whitford 1 2 , Kathryn Collins 3 , Linley Denson 1
  2. Cancer Council Australia, Sydney, NSW, Australia

Background: Despite high 5-year survival for some gynaecological cancers (≤ 82%), little research addresses survivorship concerns in this group. Fear of cancer recurrence (FCR) has been ranked the largest concern/unmet need for gynaecological cancer survivors, evidencing associations with poor quality-of-life and increased psychological morbidity.

Aim: To investigate predictors of FCR in early-to-mid stage gynaecological cancer survivors including the under-researched impact of psychological flexibility, coping styles, and single-item interpretations of illness.

Methods: Using a cross-sectional postal-questionnaire, 145 women completed demographics and standardised measures of FCR (FCRI), cancer coping styles (MAC), interpretation of illness (IIQ), psychological flexibility (AAQ-II), and mood (DASS21).

Results: A majority of participants (M=61 years) were married (53.3%) with children, had a tertiary education (31.1%), and were not currently working (60.0%). Diagnoses were mixed, time since diagnosis ranged from 1-32 years (M=5 years) with 15.9% acute survivors (< 1 year post-diagnosis). A linear regression, including eight predictors with moderate-to-large univariate associations (r≥.40), evidenced a significant model (p=.000) accounting for 63% of the variance on FCR (adjusted R2). Significant individual predictors included greater anxiously preoccupied coping style (β=.51), ‘threat/enemy’ interpretations of cancer (β=.17), poorer quality-of-life (β= -.18), and greater fatalistic coping (β=.14). Other predictors (depression, helpless/hopeless coping, ‘punishment’ interpretations, and psychological flexibility) were not significant.

Conclusions: Compared to FCRI norms, participants appeared less concerned about cancer recurrence despite most being extended/permanent survivors (1+ years post-diagnosis), perhaps reflecting accurate expectations of good survival among gynaecological cancer survivors compared with other cancer types. Respondents’ anxiously preoccupied coping style best predicted FCR, potentially highlighting a focus for intervention. Although single-item ‘threat/enemy’ interpretations of cancer appeared predictive of FCR and could act as a quick screening item, prediction was small-to-moderate in size, thus research into the previously proposed screening ability of the 9-item FCRI Severity subscale is warranted to determine the better tool.
