Here’s what you don’t want to do late on a Sunday night. You do not want to type seven letters into Google. That’s all I did. I typed: “a-r-e”. And then “j-e-w-s”. Since 2008, Google has attempted to predict what question you might be asking and offers you a choice. And this is what it did. It offered me a choice of potential questions it thought I might want to ask: “are jews a race?”, “are jews white?”, “are jews christians?”, and finally, “are jews evil?” Are Jews evil? It’s not a question I’ve ever thought of asking. I hadn’t gone looking for it. But there it was. I press enter. A page of results appears. This was Google’s question. And this was Google’s answer: Jews are evil. Because there, on my screen, was the proof: an entire page of results, nine out of 10 of which “confirm” this. The top result, from a site called Listovative, has the headline: “Top 10 Major Reasons Why People Hate Jews.” I click on it: “Jews today have taken over marketing, militia, medicinal, technological, media, industrial, cinema challenges etc and continue to face the worlds [sic] envy through unexplained success stories given their inglorious past and vermin like repression all over Europe.” Google is search. It’s the verb, to Google. It’s what we all do, all the time, whenever we want to know anything. We Google it. The site handles at least 63,000 searches a second, 5.5bn a day. Its mission as a company, the one-line overview that has informed the company since its foundation and is still the banner headline on its corporate website today, is to “organise the world’s information and make it universally accessible and useful”. It strives to give you the best, most relevant results. And in this instance the third-best, most relevant result to the search query “are Jews… ” is a link to an article from stormfront.org, a neo-Nazi website. The fifth is a YouTube video: “Why the Jews are Evil. Why we are against them.” The sixth is from Yahoo Answers: “Why are Jews so evil?” The seventh result is: “Jews are demonic souls from a different world.” And the 10th is from jesus-is-saviour.com: “Judaism is Satanic!” There’s one result in the 10 that offers a different point of view. It’s a link to a rather dense, scholarly book review from thetabletmag.com, a Jewish magazine, with the unfortunately misleading headline: “Why Literally Everybody In the World Hates Jews.” I feel like I’ve fallen down a wormhole, entered some parallel universe where black is white, and good is bad. Though later, I think that perhaps what I’ve actually done is scraped the topsoil off the surface of 2016 and found one of the underground springs that has been quietly nurturing it. It’s been there all the time, of course. Just a few keystrokes away… on our laptops, our tablets, our phones. This isn’t a secret Nazi cell lurking in the shadows. It’s hiding in plain sight. Stories about fake news on Facebook have dominated certain sections of the press for weeks following the American presidential election, but arguably this is even more powerful, more insidious. Frank Pasquale, professor of law at the University of Maryland, and one of the leading academic figures calling for tech companies to be more open and transparent, calls the results “very profound, very troubling”. He came across a similar instance in 2006 when, “If you typed ‘Jew’ in Google, the first result was jewwatch.org. It was ‘look out for these awful Jews who are ruining your life’. And the Anti-Defamation League went after them and so they put an asterisk next to it which said: ‘These search results may be disturbing but this is an automated process.’ But what you’re showing – and I’m very glad you are documenting it and screenshotting it – is that despite the fact they have vastly researched this problem, it has gotten vastly worse.” And ordering of search results does influence people, says Martin Moore, director of the Centre for the Study of Media, Communication and Power at King’s College, London, who has written at length on the impact of the big tech companies on our civic and political spheres. “There’s large-scale, statistically significant research into the impact of search results on political views. And the way in which you see the results and the types of results you see on the page necessarily has an impact on your perspective.” Fake news, he says, has simply “revealed a much bigger problem. These companies are so powerful and so committed to disruption. They thought they were disrupting politics but in a positive way. They hadn’t thought about the downsides. These tools offer remarkable empowerment, but there’s a dark side to it. It enables people to do very cynical, damaging things.” Google is knowledge. It’s where you go to find things out. And evil Jews are just the start of it. There are also evil women. I didn’t go looking for them either. This is what I type: “a-r-e w-o-m-e-n”. And Google offers me just two choices, the first of which is: “Are women evil?” I press return. Yes, they are. Every one of the 10 results “confirms” that they are, including the top one, from a site called sheddingoftheego.com, which is boxed out and highlighted: “Every woman has some degree of prostitute in her. Every woman has a little evil in her… Women don’t love men, they love what they can do for them. It is within reason to say women feel attraction but they cannot love men.” Next I type: “a-r-e m-u-s-l-i-m-s”. And Google suggests I should ask: “Are Muslims bad?” And here’s what I find out: yes, they are. That’s what the top result says and six of the others. Without typing anything else, simply putting the cursor in the search box, Google offers me two new searches and I go for the first, “Islam is bad for society”. In the next list of suggestions, I’m offered: “Islam must be destroyed.” Jews are evil. Muslims need to be eradicated. And Hitler? Do you want to know about Hitler? Let’s Google it. “Was Hitler bad?” I type. And here’s Google’s top result: “10 Reasons Why Hitler Was One Of The Good Guys” I click on the link: “He never wanted to kill any Jews”; “he cared about conditions for Jews in the work camps”; “he implemented social and cultural reform.” Eight out of the other 10 search results agree: Hitler really wasn’t that bad. A few days later, I talk to Danny Sullivan, the founding editor of SearchEngineLand.com. He’s been recommended to me by several academics as one of the most knowledgeable experts on search. Am I just being naive, I ask him? Should I have known this was out there? “No, you’re not being naive,” he says. “This is awful. It’s horrible. It’s the equivalent of going into a library and asking a librarian about Judaism and being handed 10 books of hate. Google is doing a horrible, horrible job of delivering answers here. It can and should do better.” He’s surprised too. “I thought they stopped offering autocomplete suggestions for religions in 2011.” And then he types “are women” into his own computer. “Good lord! That answer at the top. It’s a featured result. It’s called a “direct answer”. This is supposed to be indisputable. It’s Google’s highest endorsement.” That every women has some degree of prostitute in her? “Yes. This is Google’s algorithm going terribly wrong.” I contacted Google about its seemingly malfunctioning autocomplete suggestions and received the following response: “Our search results are a reflection of the content across the web. This means that sometimes unpleasant portrayals of sensitive subject matter online can affect what search results appear for a given query. These results don’t reflect Google’s own opinions or beliefs – as a company, we strongly value a diversity of perspectives, ideas and cultures.” Google isn’t just a search engine, of course. Search was the foundation of the company but that was just the beginning. Alphabet, Google’s parent company, now has the greatest concentration of artificial intelligence experts in the world. It is expanding into healthcare, transportation, energy. It’s able to attract the world’s top computer scientists, physicists and engineers. It’s bought hundreds of start-ups, including Calico, whose stated mission is to “cure death” and DeepMind, which aims to “solve intelligence”. And 20 years ago it didn’t even exist. When Tony Blair became prime minister, it wasn’t possible to Google him: the search engine had yet to be invented. The company was only founded in 1998 and Facebook didn’t appear until 2004. Google’s founders Sergey Brin and Larry Page are still only 43. Mark Zuckerberg of Facebook is 32. Everything they’ve done, the world they’ve remade, has been done in the blink of an eye. But it seems the implications about the power and reach of these companies is only now seeping into the public consciousness. I ask Rebecca MacKinnon, director of the Ranking Digital Rights project at the New America Foundation, whether it was the recent furore over fake news that woke people up to the danger of ceding our rights as citizens to corporations. “It’s kind of weird right now,” she says, “because people are finally saying, ‘Gee, Facebook and Google really have a lot of power’ like it’s this big revelation. And it’s like, ‘D’oh.’” MacKinnon has a particular expertise in how authoritarian governments adapt to the internet and bend it to their purposes. “China and Russia are a cautionary tale for us. I think what happens is that it goes back and forth. So during the Arab spring, it seemed like the good guys were further ahead. And now it seems like the bad guys are. Pro-democracy activists are using the internet more than ever but at the same time, the adversary has gotten so much more skilled.” Last week Jonathan Albright, an assistant professor of communications at Elon University in North Carolina, published the first detailed research on how rightwing websites had spread their message. “I took a list of these fake news sites that was circulating, I had an initial list of 306 of them and I used a tool – like the one Google uses – to scrape them for links and then I mapped them. So I looked at where the links went – into YouTube and Facebook, and between each other, millions of them… and I just couldn’t believe what I was seeing. “They have created a web that is bleeding through on to our web. This isn’t a conspiracy. There isn’t one person who’s created this. It’s a vast system of hundreds of different sites that are using all the same tricks that all websites use. They’re sending out thousands of links to other sites and together this has created a vast satellite system of rightwing news and propaganda that has completely surrounded the mainstream media system.” He found 23,000 pages and 1.3m hyperlinks. “And Facebook is just the amplification device. When you look at it in 3D, it actually looks like a virus. And Facebook was just one of the hosts for the virus that helps it spread faster. You can see the New York Times in there and the Washington Post and then you can see how there’s a vast, vast network surrounding them. The best way of describing it is as an ecosystem. This really goes way beyond individual sites or individual stories. What this map shows is the distribution network and you can see that it’s surrounding and actually choking the mainstream news ecosystem.” Like a cancer? “Like an organism that is growing and getting stronger all the time.” Charlie Beckett, a professor in the school of media and communications at LSE, tells me: “We’ve been arguing for some time now that plurality of news media is good. Diversity is good. Critiquing the mainstream media is good. But now… it’s gone wildly out of control. What Jonathan Albright’s research has shown is that this isn’t a byproduct of the internet. And it’s not even being done for commercial reasons. It’s motivated by ideology, by people who are quite deliberately trying to destabilise the internet.” Albright’s map also provides a clue to understanding the Google search results I found. What these rightwing news sites have done, he explains, is what most commercial websites try to do. They try to find the tricks that will move them up Google’s PageRank system. They try and “game” the algorithm. And what his map shows is how well they’re doing that. That’s what my searches are showing too. That the right has colonised the digital space around these subjects – Muslims, women, Jews, the Holocaust, black people – far more effectively than the liberal left. “It’s an information war,” says Albright. “That’s what I keep coming back to.” But it’s where it goes from here that’s truly frightening. I ask him how it can be stopped. “I don’t know. I’m not sure it can be. It’s a network. It’s far more powerful than any one actor.” So, it’s almost got a life of its own? “Yes, and it’s learning. Every day, it’s getting stronger.” The more people who search for information about Jews, the more people will see links to hate sites, and the more they click on those links (very few people click on to the second page of results) the more traffic the sites will get, the more links they will accrue and the more authoritative they will appear. This is an entirely circular knowledge economy that has only one outcome: an amplification of the message. Jews are evil. Women are evil. Islam must be destroyed. Hitler was one of the good guys. And the constellation of websites that Albright found – a sort of shadow internet – has another function. More than just spreading rightwing ideology, they are being used to track and monitor and influence anyone who comes across their content. “I scraped the trackers on these sites and I was absolutely dumbfounded. Every time someone likes one of these posts on Facebook or visits one of these websites, the scripts are then following you around the web. And this enables data-mining and influencing companies like Cambridge Analytica to precisely target individuals, to follow them around the web, and to send them highly personalised political messages. This is a propaganda machine. It’s targeting people individually to recruit them to an idea. It’s a level of social engineering that I’ve never seen before. They’re capturing people and then keeping them on an emotional leash and never letting them go.” Cambridge Analytica, an American-owned company based in London, was employed by both the Vote Leave campaign and the Trump campaign. Dominic Cummings, the campaign director of Vote Leave, has made few public announcements since the Brexit referendum but he did say this: “If you want to make big improvements in communication, my advice is – hire physicists.” Steve Bannon, founder of Breitbart News and the newly appointed chief strategist to Trump, is on Cambridge Analytica’s board and it has emerged that the company is in talks to undertake political messaging work for the Trump administration. It claims to have built psychological profiles using 5,000 separate pieces of data on 220 million American voters. It knows their quirks and nuances and daily habits and can target them individually. “They were using 40-50,000 different variants of ad every day that were continuously measuring responses and then adapting and evolving based on that response,” says Martin Moore of Kings College. Because they have so much data on individuals and they use such phenomenally powerful distribution networks, they allow campaigns to bypass a lot of existing laws. “It’s all done completely opaquely and they can spend as much money as they like on particular locations because you can focus on a five-mile radius or even a single demographic. Fake news is important but it’s only one part of it. These companies have found a way of transgressing 150 years of legislation that we’ve developed to make elections fair and open.” Did such micro-targeted propaganda – currently legal – swing the Brexit vote? We have no way of knowing. Did the same methods used by Cambridge Analytica help Trump to victory? Again, we have no way of knowing. This is all happening in complete darkness. We have no way of knowing how our personal data is being mined and used to influence us. We don’t realise that the Facebook page we are looking at, the Google page, the ads that we are seeing, the search results we are using, are all being personalised to us. We don’t see it because we have nothing to compare it to. And it is not being monitored or recorded. It is not being regulated. We are inside a machine and we simply have no way of seeing the controls. Most of the time, we don’t even realise that there are controls. Rebecca MacKinnon says that most of us consider the internet to be like “the air that we breathe and the water that we drink”. It surrounds us. We use it. And we don’t question it. “But this is not a natural landscape. Programmers and executives and editors and designers, they make this landscape. They are human beings and they all make choices.” But we don’t know what choices they are making. Neither Google or Facebook make their algorithms public. Why did my Google search return nine out of 10 search results that claim Jews are evil? We don’t know and we have no way of knowing. Their systems are what Frank Pasquale describes as “black boxes”. He calls Google and Facebook “a terrifying duopoly of power” and has been leading a growing movement of academics who are calling for “algorithmic accountability”. “We need to have regular audits of these systems,” he says. “We need people in these companies to be accountable. In the US, under the Digital Millennium Copyright Act, every company has to have a spokesman you can reach. And this is what needs to happen. They need to respond to complaints about hate speech, about bias.” Is bias built into the system? Does it affect the kind of results that I was seeing? “There’s all sorts of bias about what counts as a legitimate source of information and how that’s weighted. There’s enormous commercial bias. And when you look at the personnel, they are young, white and perhaps Asian, but not black or Hispanic and they are overwhelmingly men. The worldview of young wealthy white men informs all these judgments.” Later, I speak to Robert Epstein, a research psychologist at the American Institute for Behavioural Research and Technology, and the author of the study that Martin Moore told me about (and that Google has publicly criticised), showing how search-rank results affect voting patterns. On the other end of the phone, he repeats one of the searches I did. He types “do blacks…” into Google. “Look at that. I haven’t even hit a button and it’s automatically populated the page with answers to the query: ‘Do blacks commit more crimes?’ And look, I could have been going to ask all sorts of questions. ‘Do blacks excel at sports’, or anything. And it’s only given me two choices and these aren’t simply search-based or the most searched terms right now. Google used to use that but now they use an algorithm that looks at other things. Now, let me look at Bing and Yahoo. I’m on Yahoo and I have 10 suggestions, not one of which is ‘Do black people commit more crime?’ “And people don’t question this. Google isn’t just offering a suggestion. This is a negative suggestion and we know that negative suggestions depending on lots of things can draw between five and 15 more clicks. And this all programmed. And it could be programmed differently.” What Epstein’s work has shown is that the contents of a page of search results can influence people’s views and opinions. The type and order of search rankings was shown to influence voters in India in double-blind trials. There were similar results relating to the search suggestions you are offered. “The general public are completely in the dark about very fundamental issues regarding online search and influence. We are talking about the most powerful mind-control machine ever invented in the history of the human race. And people don’t even notice it.” Damien Tambini, an associate professor at the London School of Economics, who focuses on media regulation, says that we lack any sort of framework to deal with the potential impact of these companies on the democratic process. “We have structures that deal with powerful media corporations. We have competition laws. But these companies are not being held responsible. There are no powers to get Google or Facebook to disclose anything. There’s an editorial function to Google and Facebook but it’s being done by sophisticated algorithms. They say it’s machines not editors. But that’s simply a mechanised editorial function.” And the companies, says John Naughton, the Observer columnist and a senior research fellow at Cambridge University, are terrified of acquiring editorial responsibilities they don’t want. “Though they can and regularly do tweak the results in all sorts of ways.” Certainly the results about Google on Google don’t seem entirely neutral. Google “Is Google racist?” and the featured result – the Google answer boxed out at the top of the page – is quite clear: no. It is not. But the enormity and complexity of having two global companies of a kind we have never seen before influencing so many areas of our lives is such, says Naughton, that “we don’t even have the mental apparatus to even know what the problems are”. And this is especially true of the future. Google and Facebook are at the forefront of AI. They are going to own the future. And the rest of us can barely start to frame the sorts of questions we ought to be asking. “Politicians don’t think long term. And corporations don’t think long term because they’re focused on the next quarterly results and that’s what makes Google and Facebook interesting and different. They are absolutely thinking long term. They have the resources, the money, and the ambition to do whatever they want. “They want to digitise every book in the world: they do it. They want to build a self-driving car: they do it. The fact that people are reading about these fake news stories and realising that this could have an effect on politics and elections, it’s like, ‘Which planet have you been living on?’ For Christ’s sake, this is obvious.” “The internet is among the few things that humans have built that they don’t understand.” It is “the largest experiment involving anarchy in history. Hundreds of millions of people are, each minute, creating and consuming an untold amount of digital content in an online world that is not truly bound by terrestrial laws.” The internet as a lawless anarchic state? A massive human experiment with no checks and balances and untold potential consequences? What kind of digital doom-mongerer would say such a thing? Step forward, Eric Schmidt – Google’s chairman. They are the first lines of the book, The New Digital Age, that he wrote with Jared Cohen. We don’t understand it. It is not bound by terrestrial laws. And it’s in the hands of two massive, all-powerful corporations. It’s their experiment, not ours. The technology that was supposed to set us free may well have helped Trump to power, or covertly helped swing votes for Brexit. It has created a vast network of propaganda that has encroached like a cancer across the entire internet. This is a technology that has enabled the likes of Cambridge Analytica to create political messages uniquely tailored to you. They understand your emotional responses and how to trigger them. They know your likes, dislikes, where you live, what you eat, what makes you laugh, what makes you cry. And what next? Rebecca MacKinnon’s research has shown how authoritarian regimes reshape the internet for their own purposes. Is that what’s going to happen with Silicon Valley and Trump? As Martin Moore points out, the president-elect claimed that Apple chief executive Tim Cook called to congratulate him soon after his election victory. “And there will undoubtedly be be pressure on them to collaborate,” says Moore. Journalism is failing in the face of such change and is only going to fail further. New platforms have put a bomb under the financial model – advertising – resources are shrinking, traffic is increasingly dependent on them, and publishers have no access, no insight at all, into what these platforms are doing in their headquarters, their labs. And now they are moving beyond the digital world into the physical. The next frontiers are healthcare, transportation, energy. And just as Google is a near-monopoly for search, its ambition to own and control the physical infrastructure of our lives is what’s coming next. It already owns our data and with it our identity. What will it mean when it moves into all the other areas of our lives? “At the moment, there’s a distance when you Google ‘Jews are’ and get ‘Jews are evil’,” says Julia Powles, a researcher at Cambridge on technology and law. “But when you move into the physical realm, and these concepts become part of the tools being deployed when you navigate around your city or influence how people are employed, I think that has really pernicious consequences.” Powles is shortly to publish a paper looking at DeepMind’s relationship with the NHS. “A year ago, 2 million Londoners’ NHS health records were handed over to DeepMind. And there was complete silence from politicians, from regulators, from anyone in a position of power. This is a company without any healthcare experience being given unprecedented access into the NHS and it took seven months to even know that they had the data. And that took investigative journalism to find it out.” The headline was that DeepMind was going to work with the NHS to develop an app that would provide early warning for sufferers of kidney disease. And it is, but DeepMind’s ambitions – “to solve intelligence” – goes way beyond that. The entire history of 2 million NHS patients is, for artificial intelligence researchers, a treasure trove. And, their entry into the NHS – providing useful services in exchange for our personal data – is another massive step in their power and influence in every part of our lives. Because the stage beyond search is prediction. Google wants to know what you want before you know yourself. “That’s the next stage,” says Martin Moore. “We talk about the omniscience of these tech giants, but that omniscience takes a huge step forward again if they are able to predict. And that’s where they want to go. To predict diseases in health. It’s really, really problematic.” For the nearly 20 years that Google has been in existence, our view of the company has been inflected by the youth and liberal outlook of its founders. Ditto Facebook, whose mission, Zuckberg said, was not to be “a company. It was built to accomplish a social mission to make the world more open and connected.” It would be interesting to know how he thinks that’s working out. Donald Trump is connecting through exactly the same technology platforms that supposedly helped fuel the Arab spring; connecting to racists and xenophobes. And Facebook and Google are amplifying and spreading that message. And us too – the mainstream media. Our outrage is just another node on Jonathan Albright’s data map. “The more we argue with them, the more they know about us,” he says. “It all feeds into a circular system. What we’re seeing here is new era of network propaganda.” We are all points on that map. And our complicity, our credulity, being consumers not concerned citizens, is an essential part of that process. And what happens next is down to us. “I would say that everybody has been really naive and we need to reset ourselves to a much more cynical place and proceed on that basis,” is Rebecca MacKinnon’s advice. “There is no doubt that where we are now is a very bad place. But it’s we as a society who have jointly created this problem. And if we want to get to a better place, when it comes to having an information ecosystem that serves human rights and democracy instead of destroying it, we have to share responsibility for that.” Are Jews evil? How do you want that question answered? This is our internet. Not Google’s. Not Facebook’s. Not rightwing propagandists. And we’re the only ones who can reclaim it.

Magnetic nanoparticles for hyperthermic treatment of cancers have gained significant attention in recent years. In magnetic hyperthermia, three independent mechanisms result in thermal energy upon stimulation: Néel relaxation, Brownian relaxation, and hysteresis loss. The relative contribution of each is strongly dependent on size, shape, crystalline anisotropy, and degree of aggregation or agglomeration of the nanoparticles. We review the effects of each of these physical mechanisms in light of recent experimental studies and suggest routes for progress in the field. Particular attention is given to the influence of the collective behaviors of nanoparticles in suspension. A number of recent studies have probed the effect of nanoparticle concentration on heating efficiency and have reported superficially contradictory results. We contextualize these studies and show that they consistently indicate a decrease in magnetic relaxation time with increasing nanoparticle concentration, in both Brownian- and Néel-dominated regimes. This leads to a predictable effect on heating efficiency and alleviates a significant source of confusion within the field. © 2013 Elsevier B.V.

Climate change is profoundly affecting the evolutionary trajectory of individual species and ecological communities, in part through the creation of novel species assemblages. How climate change will influence competitive interactions has been an active area of research. Far less attention, however, has been given to altered reproductive interactions. Yet, reproductive interactions between formerly isolated species are inevitable as populations shift geographically and temporally as a result of climate change, potentially resulting in introgression, speciation, or even extinction. The susceptibility of hybridization rates to anthropogenic disturbance was first recognized in the 1930s. To date, work on anthropogenically mediated hybridization has focused primarily on either physical habitat disturbance or species invasion. Here, I review recent literature on hybridization to identify how ecological responses to climate change will increase the likelihood of hybridization via the dissolution of species barriers maintained by habitat, time, or behavior. Using this literature, I identify several cases where novel hybrid zones have recently formed, likely as a result of changing climate. Future research should focus on identifying areas and taxonomic groups where reproductive species interactions are most likely to be influenced by climate change. Furthermore, a better understanding of the evolutionary consequences of climate-mediated secondary contact is urgently needed. Paradoxically, hybridization is both a major conservation concern and an important source of novel genetic and phenotypic variation. Hybridization may therefore both contribute to increasing rates of extinction and stimulate the creation of novel phenotypes that will speed adaptation to novel climates. Predicting which result will occur following secondary contact will be an important contribution to conservation for many species. Climate change is dramatically altering the distribution and behavior of thousands of species. An increased opportunity for hybridization is one potential consequence of this reshuffling of biodiversity. This work reviews current examples of climate-mediated hybridization and provides suggestions for future areas of research. © 2014 The Author.

For online consumer reviews to serve as decision-making aids, users have to first trust the reviewer. However, unlike face-to-face communication, where trust develops overtime, consumers have to rely on personal profile information to establish confidence in the reviewer in online shopping context. These personal profile characteristics may serve as cues of source credibility. This study adopts a 2 (number of trusted members: small, large) × 2 (profile picture: without, with) × 2 (review valence: negative, positive) between-participants experiment to explore how two personal profile characteristics, reputation cue and profile picture, influence cognitive trust and affective trust towards the reviewer and perceived review credibility respectively and in a combinatory manner. The findings of the study showed that reputation cue and profile picture cue contributed differently to users' affective trust and cognitive trust towards the reviewer. Reputation cue, generated by the system, was found to influence both affective and cognitive dimensions of trust, whereas the self-generated cue of profile picture affected only affective trust. Reputation cue had a direct influence on perceived review credibility, whereas the influence of profile picture on perceived review credibility was dependent upon review valence. The implications of these findings are discussed in the paper. © 2014 Elsevier Ltd. All rights reserved.

This NSF CRI supported Research at Undergraduate Institutions (RUI) project will integrate, expand and enhance several distinct data sources currently used by three research communities: those who study Free, Libre, and Open Source Software (FLOSS), the larger empirical software engineering research community, and researchers engaged in data mining and text mining. The project will fully integrate existing data commons with several other popular data sources being used by these research communities. This integrated and enhanced data commons will continue to serve as a valuable opportunity for undergraduate research students and under-represented groups to participate directly in FLOSS and software engineering research. The tools will be collaboratively developed by the team and freely licensed for others to use and build upon. The project will ultimately benefit society by enabling an increased quantity and quality of research on how FLOSS is made, as well as better research in areas beyond FLOSS, such as commercial software engineering and data/text mining. The research community will also continue to be a model for sharing scientific resources.

Further expansion of FLOSS will include collecting, storing, and curating new text artifacts from the software engineering process, enhancing the suite of text mining software tools, specifically to search and analyze these new artifacts inside the data commons. The new focus will be on the use of graph databases for understanding networks of software developers, document-oriented databases such as a NoSQL key-value store with map-reduce for querying unstructured text. The data/text mining enhancements will allow empirical software engineering researchers and data miners to finally have access to high-quality, very large collections of real communication artifacts, and the tools to analyze them and share results. The text data collected will be some of the largest curated collections of semi-structured and unstructured text available anywhere for public use, including new data sources never collected before.

The objective of this project is to develop the Application Security IDE (ASIDE) plug-in for Eclipse that warns programmers of potential vulnerabilities in their code and assists them in addressing these vulnerabilities. The tool serves as an always available reminder and educational opportunity during any coding activities. The tool is designed to address input validation vulnerabilities; output encoding; authentication and authorization; and several race condition vulnerabilities.

The goals of this project are: (a) develop and deploy a usable tool that can serve a wide range of students and courses; (b) improve student awareness and understanding of security vulnerabilities in software; (c) increase utilization of secure programming techniques in assignments; and (d) have minimal impact on other course objectives and instructors. ASIDE is used in a range of programming courses, from CS1 to advanced Web programming, at three universities. The project evaluates how students use the tool, the impact on assignments, students vulnerability awareness, and the impact on the course instructors. The proposed approach investigates whether integrating educational support into an IDE overcomes some of these challenges and provides effective training throughout a students education.

The ASIDE plug-in can be utilized by a wide variety of students throughout their academic and professional careers. The tool is expected to be adopted by a wide audience and has the potential to improve the security knowledge of students at all levels. The project has a direct impact on students at multiple levels at different institutions, including an HBCU and an undergraduate liberal arts university. The ASIDE plug-in is available for download on the projects website.

With this award from the Major Research Instrumentation (MRI) program, Professor Victoria Moore from Elon University and colleagues Karl Sienerth and Kathryn Matera will acquire a multimode quad-monochromator plate reader spectrophotometer. The proposal is aimed at enhancing research training and education, especially in areas such as (a) peptide aggregates; (b) protein-protein binding; (c) biochemical changes to mitochondria during apoptosis; and (d) quantitative measurements of environmental and explosive compounds.

This award will provide a multimode spectrophotometer to make absorbance, fluorescence and luminescence measurements on various samples. These are standard spectroscopy techniques used to assay small volumes of solutions in chemistry and biochemistry. Reactions can be followed and quantities of materials determined. This acquisition will provide a basic instrument for current biochemistry and chemistry research by faculty and undergraduate students. Students will be trained to use the most up-to-date assays and technologies which they will encounter after graduation.

Many educators acknowledge that the millennial generation of students learns like no other, yet little has been done to alter laboratory instruction in response to this generational shift. This project will conduct educational research that evaluates the use of the Case Study Teaching in the Sciences method to improve laboratory instruction. This educational pedagogy promotes the use of cases, or interactive stories, to engage students in STEM courses and to help reform STEM instruction. The cases will be used to introduce the lab concepts as a way to bring relevance to the analytical skills being learned in the lab. The overarching goal for this project is to reform laboratory step-by-step instruction to a method that will be more active, engaging and relevant to millennial learners. More specifically, the project will evaluate student learning preferences, student engagement, retention of material, and learning of course concepts using the case studies method. Qualitative and quantitative assessment will be conducted to evaluate student perceptions for use of the methods, student learning gains, and critical thinking of students in biology, environmental engineering, and introductory engineering courses. This study will evaluate and compare data based on gender, ethnicity, and institutional type across three very different university environments. This work has the potential for broad impact because there is widespread interest in improving educational practices across STEM fields. The goal for this work will be to determine if the case studies for laboratory instruction can potentially provide a crosscutting new paradigm for lab instruction.

The Elon University Phase I Noyce Scholars Program, a partnership between Elon University and the Alamance-Burlington School System, is recruiting, preparing, and supporting during induction eighteen undergraduate Mathematics, Biology, Chemistry, and Physics majors as they become secondary-level teachers. Their recruitment begins with paid, education-related internships for fifty first- or second-year students (10 students per year). Among many valuable experiences, some participants serve as teaching assistants for Elon Academy, a college-access program for students with financial need and/or no family history of college. Two-year scholarships encourage talented STEM majors to complete a Teacher Education program to earn licensure (grades 9-12) in addition to their Bachelors degree in Mathematics, Biology, Chemistry, or Physics. Three cohorts (6 students per year) receive a $21,900 scholarship during both their junior and senior years. They benefit from Elons close relationship with the Alamance-Burlington School System. Field experiences in high-need high schools prepare them to fulfill their teaching obligations. Their program is supplemented with special experiences, including documented extra mentoring by university and secondary-school educators.

As Elon Noyce Scholars are meeting their obligation to teach for four years in a high-need school district, they are supported through their induction into the teaching profession program, during which time they receive mentoring from secondary-school and Elon faculty, as well as receive financial support for professional development activities and the purchase of classroom materials. The PI and two Co-PIs administer the program, supported by an Advisory Board that includes STEM professors and secondary-school teachers, an Education professor, a university administrator, a STEM educator from a local community college, and an Elon STEM student.

The Elon Noyce Project attempts the novel integration of recruitment, preparation, and induction support with the intent to increase the quantity, quality, and longevity of Elon graduates as secondary mathematics and science teachers. It also aims to answer such research questions as: What recruitment strategies are most effective in attracting students to STEM education? What elements of Elons teacher preparation programs do Scholars find most beneficial? How do Scholars compare with other new STEM teachers? How does the program affect teacher and K-12 student outcomes? Answers to these and other questions are infoming the future of STEM teacher recruitment, preparation and induction support nationally. An external Program Evaluator is measuring effectiveness and impact.

In this project funded by the Chemical Structure, Dynamics and Mechanisms Program of the Chemistry division, Professor Joel Karty of Elon University will determine the energetic contributions by resonance and inductive effects toward the driving force behind a variety of fundamental organic reactions. The project will incorporate both experimental and computational methodologies. In the experimental methodology, reaction kinetics and thermodynamics will be determined for a variety of reactions involving homologs of the species of interest. The results will then be extrapolated to arrive at the values involving the species of interest. One computational methodology, called a vinylogue extrapolation methodology, incorporates a similar strategy, by utilizing standard molecular orbital theory calculations to determine resonance and inductive contributions toward reactions involving homologs of the species of interest. The second computational methodology is a block-localized wavefunction methodology, the simplest variation of valence bond theory, which allows for the calculations of resonance energies directly. The broader impacts largely surround teaching and training undergraduates in chemistry research, and in the dissemination of that knowledge via publication in major journals, and presentations at professional meetings. Furthermore, the results have the potential to reach broader audiences, such as through their inclusion in undergraduate textbooks, and the development of undergraduate teaching labs.

This work will advance the general understanding of the roles that resonance and inductive effects play throughout chemistry. Moreover, the specific results of this project could have far-reaching impacts on rational drug design, and on the understanding of the role that the amino acid arginine has in the initiation and proliferation of certain types of cancer.
