Road Watch in the Pass is a citizen-science project that engages local citizens in reporting wildlife observations along a 44-km stretch of Highway 3 through Crowsnest Pass in southwestern Alberta, Canada. The numbers of wildlife vehicle collisions and a recent proposal to expand the highway have raised concerns from both human safety and wildlife conservation perspectives. Through the use of a web-based GIS, interested citizens can contribute information that will be instrumental in making final decisions concerning measures to mitigate the effects of highway expansion. Currently, 58 people have contributed over 713 observations to Road Watch. We performed a preliminary comparison of 11 months of Road Watch observations and wildlife mortality data for the same time period to demonstrate that the use of citizen science not only augments more conventional approaches, but also results in the emergence of new knowledge and insights. A Kappa index of agreement of 14% indicates poor agreement between the data sets, highlighting that wildlife successfully cross the highway in areas not identified by the wildlife mortality data. This has important implications for design and mitigation efforts for Highway 3 and other roadways.

Purpose: To inform the scientific debate about bullying, including cyberbullying, measurement. Methods: Two split-form surveys were conducted online among 6―17-year-olds (n = 1,200 each) to inform recommendations for cyberbullying measurement. Results: Measures that use the word bully result in prevalence rates similar to each other, irrespective of whether a definition is included, whereas measures not using the word bully are similar to each other, irrespective of whether a definition is included. A behavioral list of bullying experiences without either a definition or the word bully results in higher prevalence rates and likely measures experiences that are beyond the definition of bullying. Follow-up questions querying differential power, repetition, and bullying over time were used to examine misclassification. The measure using a definition but not the word bully appeared to have the highest rate of false positives and, therefore, the highest rate of misclassification. Across two studies, an average of 25% reported being bullied at least monthly in person compared with an average of 10% bullied online, 7% via telephone (cell or landline), and 8% via text messaging. Conclusions: Measures of bullying among English-speaking individuals in the United States should include the word bully when possible. The definition may be a useful tool for researchers, but results suggest that it does not necessarily yield a more rigorous measure of bullying victimization. Directly measuring aspects of bullying (i.e., differential power, repetition, over time) reduces misclassification. To prevent double counting across domains, we suggest the following distinctions: mode (e.g., online, in-person), type (e.g., verbal, relational), and environment (e.g., school, home). We conceptualize cyberbullying as bullying communicated through the online mode.

In this essay, we offer field notes from our ongoing ethnographic research on sex trafficking in the United States. Recent efforts to regulate websites such as Craigslist and Backpage have illuminated activist concerns regarding the role of networked technologies in the trafficking of persons and images for the purposes of sexual exploitation. We frame our understanding of trafficking and technology through a network studies approach, by describing anti-trafficking as a counter-network to the sex trafficking it seeks to address. Drawing from the work of Annelise Riles and other scholars of feminist science and technology studies, we read the anti-trafficking network through the production of expert knowledge and the crafting of anti-trafficking techniques. By exploring anti-trafficking activists' understandings of technology, we situate the activities of anti-trafficking experts and law enforcement as efforts toward network stabilization.

Teen dating violence (TDV) is a serious form of youth violence that youth fairly commonly experience. Although youth extensively use computer-mediated communication (CMC), the epidemiology of CMC-based TDV is largely unknown. This study examined how perpetration of psychological TDV using CMC compares and relates to perpetration using longer-standing modes of communication (LSMC; e.g., face-to-face). Data from the national Growing up with Media study involving adolescents aged 14―19 collected from October 2010 to February 2011 and analyzed May 2012 are reported. Analyses focused on adolescents with a history of dating (n = 615). Forty-six percent of youth daters had perpetrated psychological TDV. Of those who perpetrated in the past 12 months, 58% used only LSMC, 17% used only CMC, and 24% used both. Use of both CMC and LSMC was more likely among perpetrators who used CMC than among perpetrators who used LSMC. In addition, communication mode and type of psychological TDV behavior were separately related to frequency of perpetration. Finally, history of sexual intercourse was the only characteristic that discriminated between youth who perpetrated using different communication modes. Results suggest that perpetration of psychological TDV using CMC is prevalent and is an extension of perpetration using LSMC. Prevention should focus on preventing perpetration of LSMC-based TDV as doing so would prevent LSMC as well as CMC-based TDV.

When information practices are understood to be shaped by social context, privilege and marginalization alternately affect not only access to, but also use of information resources. In the context of information, privilege, and community, politics of marginalization drive stigmatized groups to develop collective norms for locating, sharing, and hiding information. In this paper, we investigate the information practices of a subcultural community whose activities are both stigmatized and of uncertain legal status: the extreme body modification community. We use the construct of information poverty to analyze the experiences of 18 people who had obtained, were interested in obtaining, or had performed extreme body modification procedures. With a holistic understanding of how members of this community use information, we complicate information poverty by working through concepts of stigma and community norms. Our research contributes to human information behavior scholarship on marginalized groups and to Internet studies research on how communities negotiate collective norms of information sharing online.

Risk Management is one of the key cares of any organization strategic management; proper benefit of risk management is finding risks and their solutions. In this article, we will suggest a new Strategic Risk Reduction technique for producing optimal risk reduction strategies; which reduce risk exposure for expected income by allowing several countermeasures per risk rather than one countermeasure as previous works did. Our Strategic Risk Reduction will be optimized using Ant Colony Optimization approach.

Communication. Mass media and P87-96

The phenomenon of “social media” has more to do with its cultural positioning than its technological affordances. Rooted in the broader “Web 2.0” landscape, social media helped engineers, entrepreneurs, and everyday people reimagine the role that technology could play in information dissemination, community development, and communication. While the technologies invoked by the phrase social media have a long history, what unfolded in the 2000s reconfigured socio-technical practices in significant ways. Reflecting on the brief history of social media, this essay argues for the need to better understand this phenomenon.

Background and objectives: In Kuwait, information regarding public knowledge and attitudes towards organ donation are scanty. This study aimed to evaluate public knowledge and attitude regarding organ donation and determine factors which predict them. Methods: This cross-sectional study was conducted among 630 participants recruited from 27 randomly selected public cooperative societies and private supermarkets in Kuwait. A self-administered questionnaire was used to collect data. Results: The prevalence rate of knowledge about organ donation was 68%, with a significantly higher rate among females than males (73% vs. 63%, respectively, p = 0.01). A composite score of knowledge was also higher among females than males (8.4 ± 5.8 vs. 6.8 ± 5.8, respectively, p = 0.001). In multivariate analysis, female gender (OR = 1.7; 95% CI =1.2, 2.4) and an educational level of bachelor’s degree or higher (OR = 2.6, 95% CI = 1.7, 3.9) were significant predictors of the knowledge. Among the barriers, more females than males mentioned about the fear of the operative procedures (p

INTRODUCTION:Polyneuropathy is one of the most prevalent neurologic disorders. Although several studies explored the role of the neurological examination in polyneuropathy, they were mostly restricted to specific subgroups of patients and have not correlated examination findings with symptoms and electrophysiological results. OBJECTIVES:To explore the sensitivity and specificity of different neurological examination components in patients with diverse etiologies for polyneuropathy, find the most sensitive combination of examination components for polyneuropathy detection, and correlate examination findings with symptoms and electrophysiological results. METHODS:Patients with polyneuropathy attending the neuromuscular clinic from 01/2013 to 09/2015 were evaluated. Inclusion criteria included symptomatic polyneuropathy, which was confirmed by electrophysiological studies. 47 subjects with no symptoms or electrophysiological findings suggestive for polyneuropathy, served as controls. RESULTS:The total cohort included 312 polyneuropathy patients, with a mean age of 60±14 years. Abnormal examination was found in 95%, most commonly sensory findings (86%). The most common abnormal examination components were impaired ankle reflexes (74%), vibration (73%), and pinprick (72%) sensation. Combining ankle reflex examination with vibration or pinprick perception had the highest sensitivity, of 88%. The specificities of individual examination component were generally high, excluding ankle reflexes (62%), and vibration perception (77%). Abnormal examination findings were correlated with symptomatic weakness and worse electrophysiological parameters. CONCLUSION:The neurological examination is a valid, sensitive and specific tool for diagnosing polyneuropathy, and findings correlate with polyneuropathy severity. Ankle reflex examination combined with either vibration or pinprick sensory testing is the most sensitive combination for diagnosing polyneuropathy, and should be considered minimal essential components of the physical examination in patients with suspected polyneuropathy.

Thioxoquinazolin-4(3H)-one, Anticancer activity, Antioxidant activity, Anticonvulsant activity, Molecular docking, Chemistry, and QD1-999

Abstract Background The quinazoline are an important class of medicinal compounds that possess a number of biological activities like anticancer, anticonvulsant and antioxidant etc. Results We evaluated the previously synthesized quinazoline derivatives 1–3 for their anticancer activities against three cancer cell lines (HepG2, MCF-7, and HCT-116). Among the tested compounds, quinazolines 1 and 3 were found to be more potent than the standard drug Vinblastine against HepG2 and MCF-7 cell lines. All the tested compounds had less antioxidant activity and did not exhibit any anticonvulsant activity. Also, molecular docking studies were performed to get an insight into the binding modes of the compounds with human cyclin-dependent kinase 2, butyrylcholinesterase enzyme, human gamma-aminobutyric acid receptor. These compounds showed better docking properties with the CDK2 as compared to the other two enzymes. Conclusions The overall study showed that thioxoquinazolines are suitable antitumor agents and they should be explored for other biological activities. Modification in the available lot of quinazoline and synthesis of its novel derivatives is essential to explore the potential of this class of compounds. The increase in the threat and with the emergence of drug resistance, it is important to explore and develop more efficacious drugs.

Communication. Mass media and P87-96

While few studies examine the online privacy practices or attitudes of young people of low socio-economic status (SES), they are often at the most risk of and most susceptible to privacy violations. This participatory, collaborative study of 28 low-SES young adults in the New York City area investigates how they view online information sharing. Like most Americans, our participants viewed online privacy as an individual responsibility. We make two primary contributions. First, participants revealed extensive awareness of the risks of sharing information online, and many avoided social media, self-censored, or obfuscated their contributions as a result. Second, many participants had extensive experience with policing and physical surveillance and were aware they could not avoid such encounters through their own efforts. This window into structural discrimination provides an alternate frame to that of “individual responsibility” that educators and researchers can use to conceptualize how privacy is violated online. Framing online privacy violations as inevitable and widespread may not only help foster activist anger and strategic resistance but also avoid the victim-blaming narratives of some media literacy efforts. By examining the experiences of these young people, who are often left out of mainstream discussions about privacy, we hope to show how approaches to managing the interplay of on- and offline information flows are related to marginalized social and economic positions.

Affimer, antibody, assay, Medicine, Science, Biology (General), and QH301-705.5

Molecular recognition reagents are key tools for understanding biological processes and are used universally by scientists to study protein expression, localisation and interactions. Antibodies remain the most widely used of such reagents and many show excellent performance, although some are poorly characterised or have stability or batch variability issues, supporting the use of alternative binding proteins as complementary reagents for many applications. Here we report on the use of Affimer proteins as research reagents. We selected 12 diverse molecular targets for Affimer selection to exemplify their use in common molecular and cellular applications including the (a) selection against various target molecules; (b) modulation of protein function in vitro and in vivo; (c) labelling of tumour antigens in mouse models; and (d) use in affinity fluorescence and super-resolution microscopy. This work shows that Affimer proteins, as is the case for other alternative binding scaffolds, represent complementary affinity reagents to antibodies for various molecular and cell biology applications.

BACKGROUND: Drug shortages are a serious and complex issue in any healthcare system. We conducted this study because the prevalence of drug shortages in Saudi Arabia is largely unknown, while there have been reports of shortages. OBJECTIVE: To explore the prevalence and characteristics of drug shortages as well as identify strategies to minimize their impact on patient care and safety in large hospitals. DESIGN: Questionnaire-based cross-sectional study. SETTING: Pharmacy departments in secondary and tertiary care hospitals in the city of Riyadh. SUBJECTS AND METHODS: Pharmacists in ten hospitals, categorized as Ministry of Health [MOH], MOH-affiliated medical cities, and non-MOH, were recruited using convenience sampling. The European Association of Hospital Pharmacists drug shortage questionnaire was administered to survey pharmacists about drug shortages in their hospitals. MAIN OUTCOME MEASURES: Percentages of drug class shortages, characteristics, and strategies to minimize impact on patient care and safety across each hospital sector. RESULTS: Of 200 pharmacists invited to participate, 120 pharmacists completed the questionnaire (60% response rate). Twenty-four percent were from MOH hospitals, 32% from MOH-affiliated medical cities, and 44% from non-MOH hospitals. A significantly higher percentage of pharmacists from MOH-affiliated medical cities (42.11%) reported encountering drug shortages on a daily basis compared to 13.79% and 15.09% of participants from MOH-hospitals and non-MOH hospitals, respectively (P=.001). The top three drug classes that ≥ 25% of participants reported having shortages of were cardiovascular, antineoplastic, and endocrine drugs. The two most common strategies that were reported to minimize the impact of drug shortages on patient care by more than 70% of participants were informing prescribers and recommending alternative drugs, and alerting hospital staff about the presence of drug shortages using new communication tools. CONCLUSIONS: The relatively high reported rates of drug shortages in some hospitals should encourage health policymakers to address this serious public health problem. LIMITATIONS: The generazibility of the study's findings were limited by the small sample size, convenience sampling technique, self-reported data, and the fact that only pharmacists were invited to participate.
