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.

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.

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.

Algorithms and data-driven technologies are increasingly being embraced by a variety of different sectors and institutions. This paper examines how algorithms and data-driven technologies, enacted by an organization like Facebook, can induce similarity across an industry. Using theories from organizational sociology and neoinstitutionalism, this paper traces the bureaucratic roots of Big Data and algorithms to examine the institutional dependencies that emerge and are mediated through data-driven and algorithmic logics. This type of analysis sheds light on how organizational contexts are embedded into algorithms, which can then become embedded within other organizational and individual practices. By investigating technical practices as organizational and bureaucratic, discussions about accountability and decision-making can be reframed.

This essay describes one institution’s struggle to grow its EdD program by adding an equivalent online version of a successful face-to-face program. One of the challenges faced was that of creating a comparable experience for online students to share their ongoing action research, an activity that had long been part of the face-to-face version of the program. An innovative, all-day, virtual doctoral research conference was developed and implemented. We describe our creative rethinking of the original event, towards a new, successful, and fully-online redesigned event. Although the event continues to be refined, the inaugural event proved to be a successful solution to the challenge of transferring all components of a face-to-face program over to its online equivalent. Feedback from students who participated in the conference is shared, and recommendations for other EdD programs is offered.

Creativity has become one of the most sought-after skills from graduates across business and industry. It is therefore imperative to infuse creativity training within business programs of study and professional development experiences, to remind people of their eternally curious and creative nature. The objective of this paper is to explore the literature around theories of creative potential and performance—including creative identity, creative mindset, and creative self-efficacy. We consider perspectives that reveal that creativity is a mindset predicated on beliefs and ways of thinking. Educational psychology literature and theories of creative self-belief illustrate how creative identity, mindset, and self-efficacy form the core of an individual’s belief system to think, act, and develop creatively in the world. This connects to the potential of arts-based methods as a means to infuse creative learning into business education. We illustrate how our findings can be put into practice by sharing an example of an art-based intervention that is currently in progress to develop creative capacity among students in an internationally known business program. We conclude with the idea that its incumbent upon business education, professional development, and training to incorporate methodologies that enhance creative capacity by initially eliminating or minimizing self-perceived limitations in people, such as fear, negative personal judgement, and chattering of the mind—and theories of creative self-belief provide a foundation that can undergird arts-based methods toward this goal.

Objectives: This study aimed to determine the relationship between glycaemic control and carotid atherosclerotic disease among patients with acute ischaemic stroke (AIS). Methods: This retrospective cross-sectional study took place in the Neurology Department of King Fahad Hospital of University, Khobar, Saudi Arabia, from April to October 2017. Data were collected from the medical records of 244 patients with a diagnosis of AIS confirmed by computed tomography. Doppler ultrasounds of the carotid artery were performed to determine the presence of increased carotid intima media thickness (CIMT) and plaques. Results: Significantly higher mean glycated haemoglobin (HbA1c) levels were noted in cases with high CIMT values (P = 0.002), but not in cases with carotid plaques (P = 0.360). In addition, there was a significant association between diabetes mellitus (DM) and high CIMT (P = 0.045), but not with carotid plaques (P = 0.075). Finally, while dyslipidaemia and age were independently correlated with high CIMT values (P = 0.034 and 0.050 each). Conclusion: High HbA1c levels were associated with high CIMT values, but not with carotid plaques. Therefore, HbA1c levels may be useful as an indirect marker of the initial stages of carotid artery atherosclerosis. Keywords: Glycated Hemoglobin A1c; Diabetes Mellitus; Carotid Intima-Media Thickness; Atherosclerotic Plaque; Stroke.

Background: The most effective treatment for severe acne is isotretinoin. However, it carries major side effects, such as teratogenicity, depression, and increased lipid profiles. It is advised to monitor the lipid profile and to use two forms of contraception during isotretinoin use. Although it is commonly prescribed, little data are available regarding patients' understanding of isotretinoin. Objectives: The aim of this study is to assess Saudi female college students' knowledge about isotretinoin use and side effects. Methods: Data were collected by a validated online questionnaire disseminated through social media, allowing the collection of information from students from different regions of the country. Results: The total number of responses was 622. The majority of respondents were 18–24 years old, single, and college students; all were female. About 48.6% (282) of the sample used isotretinoin. Most had good knowledge of isotretinoin side effects. Medical students were more knowledgeable than students of other majors, and users were more knowledgeable than nonusers. The most common side effect was dryness. Use among married females was 2.8%, the majority of whom were instructed by their physicians to use only one method of contraception. One respondent got pregnant while using the drug. Conclusion: College-aged females generally have good knowledge of isotretinoin and its side effects. However, awareness about proper contraceptive use while on the drug is lacking.

creative epistemologies, creative paradigms, creative thinking, creativity, creativity research, design, Social sciences (General), and H1-99

Designerly ways of knowing have significant untapped potential to inform creativity research. In this article, I draw upon in-depth interviews with expert design scholars to examine this connection. Thematic analysis reveals how design offers potential lenses on creativity that are not often taken up in dominant psychological discourses around creativity. I situate this by framing the need for design-based knowledge within creativity literature. The findings reflect a view of creativity involving perception, intuition, and ability to re-see the world; creativity as an action-orientated phenomenon; and a focus on the ethics of creativity in an increasingly technology-empowered society. In exploring scholarly definitions of and views about creativity, there are insights on how design offers distinctive viewpoints for paradigms around creativity.
