Project description:Following the highly restrictive measures adopted by many countries for combating the current pandemic, the number of individuals infected by SARS-CoV-2 and the associated number of deaths steadily decreased. This fact, together with the impossibility of maintaining the lockdown indefinitely, raises the crucial question of whether it is possible to design an exit strategy based on quantitative analysis. Guided by rigorous mathematical results, we show that this is indeed possible: we present a robust numerical algorithm which can compute the cumulative number of deaths that will occur as a result of increasing the number of contacts by a given multiple, using as input only the most reliable of all data available during the lockdown, namely the cumulative number of deaths.

Project description:BackgroundThe rise of the internet and social media has boosted online crowdfunding as a novel strategy to raise funds for kick-starting projects, but it is rarely used in science.ObjectiveWe report on an online crowdfunding campaign launched in the context of the neuroscience project HORAO. The aim of HORAO was to develop a noninvasive real-time method to visualize neuronal fiber tracts during brain surgery in order to better delineate tumors and to identify crucial cerebral landmarks. The revenue from the crowdfunding campaign was to be used to sponsor a crowdsourcing campaign for the HORAO project.MethodsWe ran a 7-week reward-based crowdfunding campaign on a national crowdfunding platform, offering optional material and experiential rewards in return for a contribution toward raising our target of Swiss francs (CHF) 50,000 in financial support (roughly equivalent to US $50,000 at the time of the campaign). We used various owned media (websites and social media), as well as earned media (press releases and news articles) to raise awareness about our project.ResultsThe production of an explanatory video took 60 hours, and 31 posts were published on social media (Facebook, Instagram, and Twitter). The campaign raised a total of CHF 69,109. Approximately half of all donations came from donors who forwent a reward (CHF 28,786, 48.74%); the other half came from donors who chose experiential and material rewards in similar proportions (CHF 14,958, 25.33% and CHF 15,315.69, 25.93%, respectively). Of those with an identifiable relationship to the crowdfunding team, patients and their relatives contributed the largest sum (CHF 17,820, 30.17%), followed by friends and family (CHF 9288, 15.73%) and work colleagues (CHF 6028, 10.21%), while 43.89% of funds came from donors who were either anonymous or had an unknown relationship to the crowdfunding team. Patients and their relatives made the largest donations, with a median value of CHF 200 (IQR 90).ConclusionsCrowdfunding proved to be a successful strategy to fund a neuroscience project and to raise awareness of a specific clinical problem. Focusing on potential donors with a personal interest in the issue, such as patients and their relatives in our project, is likely to increase funding success. Compared with traditional grant applications, new skills are needed to explain medical challenges to the crowd through video messages and social media.

Project description:Rigid n-point water models are widely used in atomistic simulations, but have known accuracy drawbacks. Increasing the number of point charges, as well as adding electronic polarizability, are two common strategies for accuracy improvements. Both strategies come at considerable computational cost, which weighs heavily against modest possible accuracy improvements in practical simulations. In an effort to provide guidance for model development, here we have explored the limiting accuracy of "electrostatically globally optimal" n-point water models in terms of their ability to reproduce properties of water dimer-a mimic of the condensed state of water. For a given n, each model is built upon a set of reference multipole moments (e.g. ab initio) and then optimized to reproduce water dimer total dipole moment. The models are then evaluated with respect to the accuracy of reproducing the geometry of the water dimer. We find that global optimization of the charge distribution alone can deliver high accuracy of the water model: for n = 4 or n = 5, the geometry of the resulting water dimer can be almost within 50 of the ab initio reference, which is half that of the experimental error margin. Thus, global optimization of the charge distribution of classical n-point water models can lead to high accuracy models. We also find that while the accuracy improvement in going from n = 3 to n = 4 is substantial, the additional accuracy increase in going from n = 4 to n = 5 is marginal. Next, we have explored accuracy limitations of the standard practice of adding electronic polarizability (via a Drude particle) to a "rigid base"-pre-optimization rigid n-point water model. The resulting model (n = 3) shows a relatively small improvement in accuracy, suggesting that the strategy of merely adding the polarizability to an inferior accuracy water model used as the base cannot fix the defects of the latter. An alternative strategy in which the parameters of the rigid base model are globally optimized along with the polarizability parameter is much more promising: the resulting 3-point polarizable model out-performs even the 5-point optimal rigid model by a large margin. We suggest that future development efforts consider 3- and 4-point polarizable models where global optimization of the "rigid base" is coupled to optimization of the polarizability to deliver globally optimal solutions.

Project description:Inclusive leadership has recently become an active topic in the literature on leadership and in the field of organizational behavior. However, there is currently a lack of consensus regarding whether the younger generation of inclusive leaders perceive and behave differently from the older generation. This study seeks to determine the traits, characteristics, attitudes, and behaviors of young inclusive Thai leaders who today play an increasingly influential role in various sectors of the Thai economy. The ultimate intent is to develop a theoretical framework for young inclusive leadership. Building on relational leadership theory and adopting the framework of Kouzes and Posner’s Leadership Practices Inventory (LPI) and Hollander’s 4Rs of Inclusive Leadership, the authors use interviews with 12 young Thai leaders to classify the crucial attributes of young inclusive Thai leaders into five categories: role model, luminary, pioneer, motivator, and nurturer. These attributes reflect how young leaders express their inclusiveness in conjunction with relational, entrepreneurial, and transformational leadership and serve as the basis for a holistic framework for young inclusive leadership.

Project description:We worked with artisanal fisherfolk along the Coromandel coast in two districts of Tamil Nadu and the Union Territory of Pondicherry in South India to map and quantify catch, gear and crew details for all fishing craft along 120 km. Spatially explicit fisheries data were collected to understand the distribution of fishing effort and to identify high pressure fishing zones. Approximately 7,945 square kilometres of fishing grounds were surveyed and 3,427 fishing trips were observed using nine GPS enabled echo-sounders operated by fishermen. Data were visualised and non parametric statistical analysis revealed distinct patterns in fishing effort, high density fishing zones and large overlaps in zones between traditional, motorised and mechanised craft. Existing marine fishing regulations for the respective regions were also evaluated and violations were mapped. Results were presented in each of the villages and then in district wide meetings with community leaders to spur discussions on resource based conflicts and fisheries management. Our findings suggest that the present trajectory of resource over-exploitation, the use of destructive fishing methods combined with the lack of compliance to current regulations will lead to a collapse of the small scale fishing industry and further intensify conflicts within the community. Recommendations made by fishing community leaders are presented and their role in local fisheries management is discussed. This study is the first of its kind for this region and can easily be replicated at regional scales to develop a better understanding of the spatial extent and nature of small scale fisheries, including conflict, for the purpose of fisheries management.

Project description:Traditional learning techniques have evolved slowly and have yet to adapt the course content delivery to today's students' approaches to acquiring new knowledge. However, micro-learning has become popular in e-Learning environments as a course design technique due to short attention spans, demand for small chunks of information, and time constraints. Hence, it has been selected for creating reading mobile applications provided to the nature of its learning approach. In order to describe the multiple iterations of design, development, and evaluation of this general framework, a methodology named Design-Based Research (DBR) is implemented. First, the article presents the abstract framework components and a cloud-based software architecture that allows a modular approach to creating such applications. The pathway developed through adapting the iPAC framework, which involves personalization, authenticity, and collaboration, is part of the methodology used to design the app under pedagogical and technological considerations. The process demanded the following phases: analysis and exploration, design and construction, evaluation and reflection, redesign and reconstruction, and final critical reflections. Four applied instruments also validate the framework implementation: The iPAC Rubric, an aphorisms checklist, a pre and post-test, a focus group, and a usability test taken by 28 students in a private university in Colombia. Findings indicated that Design-Based Research (DBR) methodology emerged as an appropriate tool to encounter the needs behind reading applications design due to its sequence of operations yields results successively closer to adequate usability standards and smooth implementation. They also reveal the positive impact of new types of texts on students' motivation and awareness toward other reading strategies and micro-learning. This impact indeed proved the proposed framework's effectiveness for designing micro-learning applications.

Project description:Decisions about the choice of a mate can greatly impact both individual fitness and selection processes. We developed a novel agent-based model to investigate two common mate choice rules that may be used by female gray treefrogs (Hyla versicolor). In this model environment, female agents using the minimum-threshold strategy found higher quality mates and traveled shorter distances on average, compared with female agents using the best-of-n strategy. Females using the minimum-threshold strategy, however, incur significant lost opportunity costs, depending on the male population quality average. The best-of-n strategy leads to significant female:female competition that limits their ability to find high quality mates. Thus, when the sex ratio is 0.8, best-of-5 and best-of-2 strategies yield mates of nearly identical quality. Although the distance traveled by females in the mating task varied depending on male spatial distribution in the environment, this did not interact with female choice for the best-of-n or minimum-threshold strategies. By incorporating empirical data from the frogs in this temporally- and spatially-explicit model, we thus show the emergence of novel interactions of common decision-making rules with realistic environmental variables.

Project description:ObjectivesThere is substantial lack of guidance when it comes to the implementation of non-technical skills (NTS) in undergraduate medical education. This review aimed to identify and critically evaluate published literature on learning strategies for NTS in undergraduate medical education and to derive a training framework targeted towards standardizing future training interventions.MethodsA systematic review of the MEDLINE database was performed using a prospective protocol following PRISMA guidelines. Studies evaluating undergraduate medical students exposed to NTS interventions, which measured subjective or objective outcomes in selected attributes, were included.ResultsInitial systematic search yielded a total of 5079 articles, out of which 68 fulfilled the inclusion criteria. A total of 24 NTS were identified, with communication skills being the most commonly reported skill evaluated (n = 37). A variety of educational tools were used (n = 32), noteworthy being the use of simulated patients. Great heterogeneity was also observed in measured outcomes and methods of assessment. A 'triad of outcomes' in NTS training was devised (knowledge, skill performance and attitude towards skills) and used for classification of all reported outcomes. Extracted data were used to design a non-technical skill training framework.ConclusionsThe existing literature describes a plethora of NTS interventions in undergraduate medical education, with varied outcomes and assessments. We hereby propose the 'NTS Training Framework', in an attempt to coordinate future research and catalyze the identification of an ideal NTS course structure to form tomorrow's physicians.

Project description:IntroductionBlack people are disproportionately impacted by homicide. However, despite this over-representation, research is limited relevant to how black individuals, families and communities cope with the chronic traumatic devastation of homicide. This scoping review will provide an amalgamation of the current literature regarding the coping strategies of black survivors of homicide victims to inform future health and social work practice.Methods and analysisIn this scoping review, Arksey and O'Malley's five-stage framework will be used to succinctly gather and synthesise previous literature and identify gaps in research relevant to black survivors of homicide victims. This method will allow for a focused process of chosen pertinent databases. The seven databases include OVID (MEDLINE and PsycINFO), ProQuest (Sociological Abstracts, Social Services Abstracts, International Bibliography of Social Sciences), EBSCO (Africa Wide, The Cumulative Index to Nursing and Allied Health Literature). The seven databases were chosen for their relevance to the topic of coping with homicide for black individuals, families and communities. All members of the research team will screen the abstracts and full texts of the literature based on the inclusion criteria. The findings will be charted and synthesised using a qualitative thematic analysis.Ethics and disseminationThe articles chosen for this review will be gathered from peer-reviewed journals and scholarly search engines. Due to this research project's nature, ethics approval is not warranted. The results of this scoping review will inform culturally responsive approaches to research, policy and practice for first responders (eg, law enforcement, emergency medical technicians) and providers (eg, mental health clinicians, physicians and faith-based communities) who frequently render services to black survivors of homicide victims. The results will be shared through journal article publications, academic and community conferences, as well as professional training opportunities for practitioners who support Black individuals, families and communities.

Project description:While emerging digital health technologies offer researchers new avenues to collect real-time data, little is known about current ethical dimensions, considerations, and challenges that are associated with conducting digital data collection in research with minors. As such, this paper reports the findings of a scoping review which explored existing literature to canvass current ethical issues that arise when using digital data collection in research with minors. Scholarly literature was searched using electronic academic databases for articles that provided explicit ethical analysis or presented empirical research that directly addressed ethical issues related to digital data collection used in research with minors. After screening 1,156 titles and abstracts, and reviewing 73 full-text articles, 20 articles were included in this review. Themes which emerged across the reviewed literature included: consent, data handling, minors' data rights, observing behaviors that may result in risk of harm to participants or others, private versus public conceptualizations of data generated through social media, and gatekeeping. Our findings indicate a degree of uncertainty which invariably exists with regards to the ethics of research that involves minors and digital technology. The reviewed literature suggests that this uncertainty can often lead to the preclusion of minors from otherwise important lines of research inquiry. While uncertainty warrants ethical consideration, increased ethical scrutiny and restricting the conduct of such research raises its own ethical challenges. We conclude by discussing and recommending the ethical merits of co-producing ethical practice between researchers and minors as a mechanism to proceed with such research while addressing concerns around uncertainty.
