A Critical Examination of the Social Organizations within Canadian NGOs in the Provision of HIV/AIDS Health Work in Tanzania

The purpose of this study was to critically examine the social organizations within Canadian non-government organizations (NGOs) in the provision of HIV/AIDS health work in Tanzania. Using a post-Marxist theoretical framework, I employed the tools of institutional ethnography to understand how distinct forms of coordinated work are reproduced and embedded within the institution of Canadian NGOs at the local site of lived experiences. Multiple, concurrent methods, including text analysis, participant observation and in-depth interviews, were utilized. Data collection occurred over approximately a 19-month period of time in Tanzania and Canada. Interviews were conducted with health work volunteers, NGO administrators and staff and bilateral agency employees. Participant observation was used to record insights from the interviews as well as observations of the participants’ everyday work experiences. Further, since text-based forms of knowledge are essential in understanding ideologies, working activities, and power relations of an institution, text-analysis was used as a data collection technique. The findings, implications and recommendations of this study were theoretically derived. Neoliberalism and neo-colonialism ruled the coordination of international volunteer health work. In this study, three social relational levels were exposed: interpersonal social relations, organizational social relations, institutional social relation. Gender, race and class were the interpersonal social relations that advantaged the international volunteer health workers as ‘experts’ over the local community. \u27Volunteer as client\u27, ‘experience as commodity\u27 and ‘free market evaluation\u27 were the organizational social relations pervasive in talk and text. Neoliberal ideology and the third sector were interwoven and worked together to inform values and activities of international health work volunteers. Finally, the three institutional social relations, ‘favoring private sector interests’, ‘hegemonic accountability’ and ‘reality disconnected from rhetoric’ exposed the conflation between aid and trade bilaterally. This study has extended our understanding of the ways in which health work volunteers, NGO administrators, and bilateral agency employees come together to produce health work in Tanzania. The findings illuminate the need to generate additional awareness and response related to social inequities embedded in international volunteer \u27health work\u27 beyond who constitutes ‘the expert’. Health promotion strategies include challenging the role of neoliberalism, including foreign trade, in the delivery of international aid

Chisel: Reliability- and Accuracy-Aware Optimization of Approximate Computational Kernels

The accuracy of an approximate computation is the distance between the result that the computation produces and the corresponding fully accurate result. The reliability of the computation is the probability that it will produce an acceptably accurate result. Emerging approximate hardware platforms provide approximate operations that, in return for reduced energy consumption and/or increased performance, exhibit reduced reliability and/or accuracy. We present Chisel, a system for reliability- and accuracy-aware optimization of approximate computational kernels that run on approximate hardware platforms. Given a combined reliability and/or accuracy specification, Chisel automatically selects approximate kernel operations to synthesize an approximate computation that minimizes energy consumption while satisfying its reliability and accuracy specification. We evaluate Chisel on five applications from the image processing, scientific computing, and financial analysis domains. The experimental results show that our implemented optimization algorithm enables Chisel to optimize our set of benchmark kernels to obtain energy savings from 8.7% to 19.8% compared to the fully reliable kernel implementations while preserving important reliability guarantees.National Science Foundation (U.S.) (Grant CCF-1036241)National Science Foundation (U.S.) (Grant CCF-1138967)National Science Foundation (U.S.) (Grant IIS-0835652)United States.

Designing open access, educational resources / Développer des ressources éducatives en libre accès

The recent bourgeoning of open educational resources has meant greater access to materials with open licenses in the public domain than ever before. Open educational resources are learning tools, such as textbooks, that are freely available and typically accessed online. Despite the expansion of open educational resources, many educators are still unacquainted with the nature and process of producing such resources. The purpose of this discussion paper is to share our experience in developing an open educational e-textbook for students in post-secondary programs for nursing and other health professions while highlighting practical tips for educators. The exemplar referenced in this paper focuses on vital signs’ measurement, a familiar concept for nurse educators, and a topic ubiquitous in healthcare. This paper is suited for any user curious about designing open educational resources with consideration of key elements to produce quality and educational resources that support excellence in nursing pedagogy. We begin by providing a background to our specific project followed by a discussion of the planning phase, the design phase, and other considerations. The e-textbook falls under a Creative Commons license and can be accessed for free by educators and learners. Résumé Le développement récent de ressources éducatives en libre accès a permis une accessibilité beaucoup plus grande, comme jamais auparavant, au matériel avec licences ouvertes dans le domaine public. Les ressources éducatives en libre accès sont des outils d’apprentissage, comme les manuels scolaires, qui sont offerts gratuitement et qui sont généralement accessibles en ligne. En dépit de la prolifération des ressources éducatives libres, bon nombre de professeurs sont toujours peu familiers avec la nature et le processus de production de telles ressources. L’objectif de ce texte de discussion est de partager notre expérience du développement d’un e-manuel de formation en libre accès, pour les étudiants inscrits dans les programmes postsecondaires pour la profession infirmière et les autres professions de la santé, tout en soulignant des conseils pratiques pour les professeurs. L’exemple, cité en référence dans ce texte, est axé sur la prise des signes vitaux, un concept familier aux infirmières enseignantes et un sujet omniprésent dans le domaine de la santé. Cet article convient à toute personne curieuse d’en apprendre davantage sur la conception des ressources éducatives en libre accès en tenant compte d’éléments clés afin de produire des ressources éducatives de qualité qui appuient l’excellence de la pédagogie en soins infirmiers. Nous établissons d’abord le contexte du projet particulier suivi d’une discussion sur la phase de planification, la phase de conception et sur d’autres éléments à considérer. Le e-manuel relève d’une licence Creative Commons et est accessible gratuitement pour les professeurs et les étudiants

Optimized intermolecular potential for nitriles based on Anisotropic United Atoms model

An extension of the Anisotropic United Atoms intermolecular potential model is proposed for nitriles. The electrostatic part of the intermolecular potential is calculated using atomic charges obtained by a simple Mulliken population analysis. The repulsion-dispersion interaction parameters for methyl and methylene groups are taken from transferable AUA4 literature parameters [Ungerer et al., J. Chem. Phys., 2000, 112, 5499]. Non-bonding Lennard-Jones intermolecular potential parameters are regressed for the carbon and nitrogen atoms of the nitrile group (–C≡N) from experimental vapor-liquid equilibrium data of acetonitrile. Gibbs Ensemble Monte Carlo simulations and experimental data agreement is very good for acetonitrile, and better than previous molecular potential proposed by Hloucha et al. [J. Chem. Phys., 2000, 113, 5401]. The transferability of the resulting potential is then successfully tested, without any further readjustment, to predict vapor-liquid phase equilibrium of propionitrile and n-butyronitrile

Why Do Dolphins Carry Sponges?

Tool use is rare in wild animals, but of widespread interest because of its relationship to animal cognition, social learning and culture. Despite such attention, quantifying the costs and benefits of tool use has been difficult, largely because if tool use occurs, all population members typically exhibit the behavior. In Shark Bay, Australia, only a subset of the bottlenose dolphin population uses marine sponges as tools, providing an opportunity to assess both proximate and ultimate costs and benefits and document patterns of transmission. We compared sponge-carrying (sponger) females to non-sponge-carrying (non-sponger) females and show that spongers were more solitary, spent more time in deep water channel habitats, dived for longer durations, and devoted more time to foraging than non-spongers; and, even with these potential proximate costs, calving success of sponger females was not significantly different from non-spongers. We also show a clear female-bias in the ontogeny of sponging. With a solitary lifestyle, specialization, and high foraging demands, spongers used tools more than any non-human animal. We suggest that the ecological, social, and developmental mechanisms involved likely (1) help explain the high intrapopulation variation in female behaviour, (2) indicate tradeoffs (e.g., time allocation) between ecological and social factors and, (3) constrain the spread of this innovation to primarily vertical transmission

Object Affordances Tune Observers' Prior Expectations about Tool-Use Behaviors

Learning about the function and use of tools through observation requires the ability to exploit one's own knowledge derived from past experience. It also depends on the detection of low-level local cues that are rooted in the tool's perceptual properties. Best known as ‘affordances’, these cues generate biomechanical priors that constrain the number of possible motor acts that are likely to be performed on tools. The contribution of these biomechanical priors to the learning of tool-use behaviors is well supported. However, it is not yet clear if, and how, affordances interact with higher-order expectations that are generated from past experience – i.e. probabilistic exposure – to enable observational learning of tool use. To address this question we designed an action observation task in which participants were required to infer, under various conditions of visual uncertainty, the intentions of a demonstrator performing tool-use behaviors. Both the probability of observing the demonstrator achieving a particular tool function and the biomechanical optimality of the observed movement were varied. We demonstrate that biomechanical priors modulate the extent to which participants' predictions are influenced by probabilistically-induced prior expectations. Biomechanical and probabilistic priors have a cumulative effect when they ‘converge’ (in the case of a probabilistic bias assigned to optimal behaviors), or a mutually inhibitory effect when they actively ‘diverge’ (in the case of probabilistic bias assigned to suboptimal behaviors)

Millennials in the Workplace: A Communication Perspective on Millennials’ Organizational Relationships and Performance

Stereotypes about Millennials, born between 1979 and 1994, depict them as self-centered, unmotivated, disrespectful, and disloyal, contributing to widespread concern about how communication with Millennials will affect organizations and how they will develop relationships with other organizational members. We review these purported characteristics, as well as Millennials’ more positive qualities—they work well in teams, are motivated to have an impact on their organizations, favor open and frequent communication with their supervisors, and are at ease with communication technologies. We discuss Millennials’ communicated values and expectations and their potential effect on coworkers, as well as how workplace interaction may change Millennials

Recent developments in genetics and medically assisted reproduction : from research to clinical applications

Two leading European professional societies, the European Society of Human Genetics and the European Society for Human Reproduction and Embryology, have worked together since 2004 to evaluate the impact of fast research advances at the interface of assisted reproduction and genetics, including their application into clinical practice. In September 2016, the expert panel met for the third time. The topics discussed highlighted important issues covering the impacts of expanded carrier screening, direct-to-consumer genetic testing, voiding of the presumed anonymity of gamete donors by advanced genetic testing, advances in the research of genetic causes underlying male and female infertility, utilisation of massively parallel sequencing in preimplantation genetic testing and non-invasive prenatal screening, mitochondrial replacement in human oocytes, and additionally, issues related to cross-generational epigenetic inheritance following IVF and germline genome editing. The resulting paper represents a consensus of both professional societies involved.Peer reviewe
