We discuss processes involved in user-centric security design, including the synthesis of goals based on security and usability tasks. We suggest the usage of implicit security and the facilitation of secureuser actions. We propose a process for evaluating usability flaws by treating them as security threats and adapting traditional HCI methods. We discuss how to correct these flaws once they are discovered. Finally, we discuss the Usable Security Development Model for developing usable secure systems.

Smartphones have become increasingly common over the past few years, and mobile games continue to be the most common type of application (Apple, Inc., 2013). For many people, the social aspect of gaming is very important, and thus most mobile games include support for playing with multiple players. However, there is a lack of common knowledge about which implementation of this functionality is most favorable from a development standpoint. In this study, we evaluate three different types of multiplayer gameplay (pass-and-play, Bluetooth, and GameCenter) via development cost and user interviews. We find that pass-and-play, the most easily-implemented mode, is not favored by players due to its inconvenience. We also find that GameCenter is not as well favored as expected due to latency of GameCenter's servers, and that Bluetooth multiplayer is the most well favored for social play due to its similarity to real-life play. Despite there being a large overhead in developing and testing Bluetooth and GameCenter multiplayer due to Apple's development process, this is irrelevant since professional developers must enroll in this process anyway. Therefore, the most effective multiplayer mode to develop is mostly determined by whether Internet play is desirable: Bluetooth if not, GameCenter if so. Future studies involving more complete development work and more types of multiplayer modes could yield more promising results.

Due to its difficult nature, organic chemistry is receiving much research attention across the nation to develop more efficient and effective means to teach it. As part of that, Dr. Ian Gould at ASU is developing an online organic chemistry educational website that provides help to students, adapts to their responses, and collects data about their performance. This thesis creative project addresses the design and implementation of an input parser for organic chemistry reagent questions, to appear on his website. After students used the form to submit questions throughout the Spring 2013 semester in Dr. Gould's organic chemistry class, the data gathered from their usage was analyzed, and feedback was collected. The feedback obtained from students was positive, and suggested that the input parser accomplished the educational goals that it sought to meet.

Beginning in the early 1990s, nuclear forensic science is a relatively young field that focuses on “re-establishing the history of nuclear material of unknown origin” (Mayer, et al. 2010, p. 1).

Beginning in the early 1990s, nuclear forensic science is a relatively young field that focuses on “re-establishing the history of nuclear material of unknown origin” (Mayer, et al. 2010, p. 1). Specifically, investigators compare these unknown materials, pre-detonation in this case, based on their characteristics and process history (Mayer, et al. 2010, p. 1). In 2010, the Committee of Nuclear Forensics made ten recommendations on the procedures that could lead to improvement in investigation methods. In particular, this paper discusses Recommendation 6: “The nuclear forensics community should develop and adhere to standards and procedures that are rooted in the applicable underlying principles that have been recommended for modern forensic science, including calibration using reference standards; cross-comparison with other methods; inter-laboratory comparisons; and identification, propagation, and characterization of uncertainties'' (Committee of Nuclear Forensics, 2010, p. 11). The main objective of this paper is to compile a literature review to determine how this recommendation was followed, if at all, and produce a list of suggestions that could complement any effort towards the improvement of the field. Out of the methods recommended, that which has fostered the most growth has been cross-comparison. For example, the need for human supervision has decreased, which has decreased the need for human error (Reading, et al., 2017, p. 6013). However, areas that would benefit from development are increasing the number of disciplines in the field (Croudace, et al., 2016, p. 128). These conclusions provided the basis for improvements to other existing studies like DNA and fingerprinting.

This paper examines the effects of childhood maltreatment on attachment and development. Humans are social beings; connection is at the core of human behavior. This social nature is what drives the need to form relationships with others. Relationships help humans learn and understand the social world around them relatively safely and securely. However, to ensure that these relationships bring safety and security, the ability to do so must be established during the first 18 months of children’s lives (Kennedy & Kennedy, 2004). The relationships humans form are based on how they establish attachments, or emotional and long-term bonds and relationships, to a primary caregiver or parent as children (Bowlby, 1969). These primary attachments include secure, anxious-preoccupied, insecure-avoidant, or fearful-avoidant attachments and can have significant effects on individuals or emerging adults in early adulthood (ages 18-25). Primary attachments act as a safe and organized view of how human interactions and relationships work and act as a secure base for children to explore and successfully understand the social world around them (Feeney & Noller, 1996). However, this depends on whether or not safety, a secure base, and an organized view of relationships are formed between the caregiver and child during the first 18 months of the child’s life. Moreover, if a child experiences maltreatment such as abuse and neglect from primary caregivers during their first 18 months of life, it can severely affect what type of attachment style is formed and how development occurs in early adulthood (Connell-Corrick, 2011). Therefore, to thoroughly understand how childhood maltreatment affects attachment and development, an overview of both attachment theory and childhood maltreatment, the effects of childhood maltreatment on both attachment and development, and the importance of protective factors, interventions, and preventions will be discussed.

This research study evaluated the effects of early childhood environment and the influence parenting style has on the life outcomes among university students who varied in psychopathic traits; demonstrating evidence to show students who scored highly in measures of psychopathy used antisocial success seeking strategies to attain common life goals. This study examined the prospect of parenting styles and childhood environment as possible influences on important differences between psychopaths who become involved in the American legal system and those who do not. These differences were identified by asking participants to describe how often they engage in success seeking behaviors by using either prosocial or antisocial methods. Results were based on a hierarchical regression analysis and illustrated psychopathy as a significant predictor for utilizing antisocial success seeking strategic behavior. Such strategies include lying on job applications, accepting credit for the work of others, or winning a competition by cheating. In contrast, our Model determined that parental influence based on measures of paternal and maternal warmth, financial support, and physical and emotional abuse, did not significantly predict either prosocial success seeking strategies or antisocial success seeking strategies. Possible trends relating to childhood environment were identified but were undoubtedly restricted due to the evidently small sample size in this study. Conclusions into this investigation affirm the necessity for additional research into this view of psychopathy and how some psychopaths may be able to utilize their unique traits to their advantage.

The steroid hormone 20-hydroxyecdysone (20E) controls molting in arthropods. The timing of 20E production, and subsequent developmental transitions, is regulated by a variety of factors including nutrition and photoperiod. Environmental factors, such as temperature, play a critical role in regulation as well. The increasing prevalence of urban heat islands (UHI), or areas with elevated temperature due to retained heat by built structures, in response to rapid urbanization has made it critical to understand how organisms respond to elevating global temperatures. Some arthropods, such as the Western black widow spider, Latrodectus hesperus, appear to thrive under UHI conditions, but the physiological mechanism underlying their success has not been explored. Recently, we have shown that L. hesperus, a troublesome urban pest, in fact responds to urban heat island conditions in Phoenix, AZ with delayed development, reduced body mass, and increased mortality. Here we look at the relationship between 20E levels and development in spiderlings reared under desert (27ᵒC), intermediate (30ᵒC), and urban (33ᵒC) temperatures, filling a noticeable gap in not only understanding ecdysteroids’ role in arachnid development but how incremental changes in environmental conditions affect the regulation of this process. Developmental progression and hemolymph 20E titers were recorded for several families of spiders collected from across the urban Phoenix area with data spanning from day 55 to 75 of development, focusing on the second developmental instar. We found that 33°C, but not 30°C, led to 1) a significantly higher production of 20E throughout development, 2) a reduced and delayed molt-inducing 20E peak, and 3) noticeable reductions in growth rate and mass. At 30°C, a variable response is seen in molt timing, without the negative impacts on size and mortality as seen at 33°C, suggesting that at UHI temperatures, the optimal developmental temperature threshold has been surpassed.
