The responsibility of sports federations to facilitate and fund concussion research and the role of active participant involvement and engagement

ABSTRACT It is generally accepted that we need more research into concussions and other injuries with potential long-term effects in sport because such research underpins effective, evidence-based prevention, management, support, and treatment. This paper provides an analysis of the obligations of sports federations to support and facilitate such research, as well as an analysis of the role active participants in the sport should have in the research process. The paper focuses on concussion and concussion research, though very similar arguments apply to other common sports injuries with potential long-term effects. The paper argues that sports federations have a moral obligation and a prudential interest in initiating, facilitating, and funding concussion research. This follows from their duty of care towards active participants and from considerations of reciprocity. The ability to discharge these research obligations depends on the resources available to a particular federation, but those who can discharge them should do so. The paper further argues that athletes and other active participants in sport should be involved in all aspects of the concussion research process from conception to design, i.e. that Active Participant Involvement and Engagement (APIE) should be a non-negotiable element of concussion research projects. This is supported by instrumental reasons, but also by philosophical argument based on standpoint epistemology and on ethical arguments related to the interests of active participants. Standpoint epistemology is the epistemological position that the knowledge a person has and can have depends on that person’s standpoint in the world. Keywords: Concussion, funding, participant involvement, sport, sport association, sport federation

A Study of Reciprocal Job Recommendation for College Graduates Integrating Semantic Keyword Matching and Social Networking

With the surge in college graduate numbers, a disparity has emerged where the supply of jobs falls short of demand, intensifying employment pressures annually. College graduates, due to their lack of historical employment data compared with job seekers in the broader society, encounter a ‘cold start’ issue in the job recommendation process. Additionally, the nature of job recommendations, which differs fundamentally from unilateral recommendations, requires consideration of reciprocity between both parties involved. This article introduces a new approach to job recommendations using college graduates as the object of study. In the screening stage, a semantic keyword iterative algorithm is applied to compute the similarity between the resume and recruitment texts. This algorithm enhances the intersectionality of keywords in the calculation process, maximizing the utilization of resume information to enhance the accuracy of text similarity calculations. The ranking phase utilizes in-school data to build a social network between college graduates and graduated students and solves the system’s cold-start problem using the social network to recommend jobs for college graduates where graduated students are employed. We introduce a dual-dimensional matching approach that incorporates both specialty and salary, building upon the amalgamated semantic keyword iterative algorithm and the social network job recommendation method, to enhance the reciprocity of job recommendations. The job recommendation method introduced herein outperforms other methods in terms of the average satisfaction rate (AR) and normalized discounted cumulative gain (NDCG), thereby confirming its superior ability to meet the job-seeking preferences of graduates and the recruitment criteria of employers. This job recommendation method offers effective assistance to graduates lacking employment experience and historical employment data, facilitating their search for more suitable job opportunities.

Merit first, need and equality second: hierarchies of justice

AbstractThe question of “Justice” still divides social research, moral philosophy, and public discourse. Three principles of distributive justice (allocation rules) occupy center stage in the debate: merit (equity, proportionality), need, and equality. Yet their relation remains diffuse, and current theory does not inform political practice. Here, we aim to develop a coherent picture with an interdisciplinary analysis. From an evolutionary point of view, the foundational principle of justice is reciprocity in social exchange (what corresponds to merit). But besides being just, justice must be effective, efficient, and communicable, thereby making justice rather a social bargain and an optimization problem. Social-psychological insights (intuitions, rules of thumb, self-bindings) can inform us when and why the two allocation principles need and equality are more likely to succeed than merit would. But both are governed by reciprocal considerations, and self-bindings help to interpret altruism as “very generalized reciprocity.” Regarding politics, the reciprocal social norm Meritocratic Principle can be implemented, and its controversy avoided, by concentrating on “non-merit,” i.e., institutionally draining the wellsprings of undeserved incomes (economic rents). Avoiding or taxing away economic rents is an effective implementation of justice in market economies.

Reimagining GO and SEND Mission Paradigms for an Age of Global Migration and World Christianity

I interrogate the principal mission terms GO and SEND from post-Christendom, post-Western, and World Christianity perspectives, considering our increasingly globalized and polarized world and the emerging context of twenty-first-century Christianity. This approach exposes some of the inherent bias in mission thinking and calls for a perspectival shift toward bidirectionality and polycentrism, as the missionary impetus can now originate anywhere and result anywhere else in the world. Christian mission is no more from the West to the Rest but increasingly from everywhere to everywhere, which requires a new consideration of dispersion and reciprocity that is embedded within a multipolar world.

Treating Workers as Essential Too: An Ethical Framework for Public Health Interventions to Prevent and Control COVID-19 Infections among Meat-processing Facility Workers and Their Communitiesin the United States.

Meat is a multi-billion-dollar industry that relies on people performing risky physical work inside meat-processing facilities over long shifts in close proximity. These workers are socially disempowered, and many are members of groups beset by historic and ongoing structural discrimination. The combination of working conditions and worker characteristics facilitate the spread of SARS-CoV-2, the virus that causes COVID-19. Workers have been expected to put their health and lives at risk during the pandemic because of government and industry pressures to keep this “essential industry” producing. Numerous interventions can significantly reduce the risks to workers and their communities; however, the industry’s implementation has been sporadic and inconsistent. With a focus on the U.S. context, this paper offers an ethical framework for infection prevention and control recommendations grounded in public health values of health and safety, interdependence and solidarity, and health equity and justice, with particular attention to considerations of reciprocity, equitable burden sharing, harm reduction, and health promotion. Meat-processing workers are owed an approach that protects their health relative to the risks of harms to them, their families, and their communities. Sacrifices from businesses benefitting financially from essential industry status are ethically warranted and should acknowledge the risks assumed by workers in the context of existing structural inequities.

DCT-Based Deep Learning of Polarimetric Scattering From a Dielectric Cylinder

Electromagnetic wave interaction with cylindrical structures plays an important role in numerous research fields. For the efficient analysis of electromagnetic scattering by cylindrical components, we previously proposed a deep learning scheme which verified that with increased abstraction capability by deep neural network (DNN), it was able to handle the highly oscillatory scattering patterns to an acceptable degree. In this letter, we extend by focusing on more efficient data structural exploration by eliminating the redundancy inherent in the bistatic scattering pattern. Two schemes based on discrete cosine transform (DCT) compression are identified with increasing complexity from 2-D to 3-D DCT, realizing compression ratios of around 26 and 58, respectively, and correspondingly training is about 11 and 14 times more efficient than our previous work on equivalent graphics processing unit (GPU) requirements. Both compression-based schemes have shown good learning capabilities in terms of accuracy and generalization potential, as demonstrated by their predictions of the complicated polarimetric bistatic scattering patterns within and outside the entire dataset and by the extremely high <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$R^{2}$ </tex-math></inline-formula> values and low root mean square errors (RMSEs) in the scatter plots. The physical considerations of reciprocity are achieved automatically. It is expected that the proposed compression-based deep learning schemes be useful in the design of future physically based inversion algorithms.

Leveraging the Intersection between Age-friendly Universities and Age-Friendly Communities

Age-friendly Universities represent a growing contribution to the worldwide age-friendly movement. For universities, the international effort aims to highlight the role higher education plays in responding to the opportunities associated with an aging population. The initiative outlines ten principles to engage older adults via collegiate mission pertaining to research, education and service. Shared practices suggest diverse and unique application of the guiding tenets across participating colleges and universities. However Age-friendly Universities are also part of a broader ecosystem, situated in geographic locales reflecting actual or prospective age-friendly community status. The global Age-friendly Community movement is a decade-old effort to improve the environments in which we age via a cyclical process. This paper identifies the intersection between Age-friendly University principles and Age-Friendly Community processes and discusses reciprocal considerations for mutual advancement of the broader movement.

“It's been a good time to reflect on…who isn't worth keeping around”: COVID-19, adolescent relationship maintenance and implications for health education

PurposeThis paper adds to the growing body of research examining the impacts of COVID-19 physical distancing measures on the everyday lives of young people. It draws on theories of “digital intimacies” and “relationship maintenance” to argue that young people’s reflections on COVID-19, physical distancing and online relationships expose larger gaps in sex, relationships and health education pedagogies.Design/methodology/approachFive semi-structured online focus groups were conducted with Canadian adolescents aged 16–19 probing their experiences of dating and platonic relationships during COVID-19. Narrative thematic analysis methods were used to develop themes outlining how physical distancing measures have affected young people’s relationship norms, expectations and values.FindingsCOVID-19 physical distancing measures and school closures appeared to create the conditions for some young people to productively reflect on the labor involved in the maintenance of their relationships in relation to considerations of proximity, reciprocity and distance. This labor was particularly articulated by female participants, many of whom expressed that life disruptions caused by COVID-19 catalyzed learning about their own relationship needs, desires and boundaries.Research limitations/implicationsResults from this research are not widely generalizable, as each participant had a unique experience with COVID-19 physical distancing measures, schooling and in-person contact. Due to anonymity measures implemented, participant narratives cannot be confidently associated with demographic surveys that hampered the ability to offer an intersectional analysis of participant experience.Originality/valueDiscussions of relationship maintenance and digital intimacies elucidate the limitations of health education’s tendency to construct adolescent relationships as existing along binaries of “healthy” and “unhealthy.” Health education might benefit from more meaningful integration of these concepts.

The Ethical Implications of Student Participation in Short-Term Experiences in Global Health

Student interest in short-term experiences in global health (STEGHs) has grown in recent years. Typically, students travel from high-income countries (HIC), standing to benefit from varied clinical exposure and participation beyond what is allowed in their home jurisdictions. Whether STEGHs benefit the hosting low- and middle-income countries (LMICs) are less clear. We seek to mitigate the ethical implications of student participation in STEGHs by examining three domains: (a) the medical scope of practice for students; (b) cultural competency; and (c) reciprocal partnerships. These domains permit further elucidation of key issues relating to ethics, and public policy, to clarify how STEGH initiatives can be evaluated. Our analysis implicates that STEGHs can be described as post-colonial enterprises that perpetuate structural violence in LMICs and may cultivate hubris and savior complexes in learners. Examination of these domains necessitates two points for further analysis and evaluation with respect to STEGHs: (1) a stronger idea of justice and distributive justice that includes considerations of structural violence and reciprocity; and (2) realignment of student global health priorities towards the communities being cared for as opposed to the benefits of high income countries and volunteers. To improve global health knowledge transfer worldwide, we advocate for reciprocity between HIC and LMIC institutions and training in the colonial history of global health. We hope these changes will reduce eurocentrism within student global healthand any potential harms.

Integrating farmland in urban green infrastructure planning. An evidence synthesis for informed policymaking

The Green Infrastructure (GI) Strategy was adopted by the European Commission in 2013, to promote the deployment of GI by integrating it into main policy areas. Despite a high level of awareness for a policy integration across sectors at the EU level, urban and peri-urban farmland (UPUF) is up to now barely considered. A systematic evidence base addressing the contributions of UPUF can support a more informed policymaking. To address this, our paper developed a first evidence synthesis, to evaluate potential of UPUF contributing to policy objectives, thereby tackling major urban challenges. Furthermore an analysis of policy documents revealed gaps on the current state of policymaking and potentials for the integration in future policies. Due to a reciprocal consideration between EU level policies and scientific knowledge this work provides information that help to further construct scientific evidence to address policy concerns while taking into account multiple perspectives. Furthermore, we discussed the implications of our findings for further UGI research and policymaking and thus hope to extend the current political debate across policy sectors.

A Quasi-Contract Theory of Political Obligation

Whether there is a general moral obligation to obey the law, often referred to as ‘political obligation’, is an enduring question in contemporary legal and political philosophy. Theories are continually being formulated, criticized, and reformulated as theorists attempt to settle this issue. However, there yet remains no general consensus as to whether any theory successfully answers this question in either the affirmative or the negative. I propose the legal doctrine of quasi-contract as a candidate for making sense of this persistent issue. While the duty to reciprocate and the principle of reasonable expectations each falls short when independently advanced as a theory of political obligation, quasi-contract, which combines reciprocity, reasonable expectations, and additional moral considerations, is able to establish a satisfactory account of political obligation.

Computation of interface wave motions by reciprocity considerations

The current theoretical study deals with computation of Stoneley waves along a solid–solid interface and Scholte waves (also called Scholte-Gogoladze) along a solid–liquid interface by reciprocity considerations. Closed-form solutions of the wave motions generated by a time-harmonic line load applied in two bonded elastic half-spaces of different material properties are derived in a simple manner. In order to perform direct applications of reciprocity theorems, we introduce in this article new expressions for the displacements of free interface waves. Reciprocity relations between an actual state, interface wave motion generated by a time-harmonic line load, and a virtual state, an appropriately chosen free wave traveling along the interface, are derived. Scattered amplitudes of Stoneley waves and Scholte waves due to the load are thus computed. To show application of the obtained results, scattering of Stoneley wave by a delamination at the interface is then studied.

Moral Ekonomi Perempuan Desa : Studi tentang Resiprositas Budaya dan Disiplin Bisnis Pengrajin Songket di Kecamatan Pemulutan Barat Kabupaten Ogan Ilir

This study discusses economic morals as a result of consideration of cultural reciprocity with business ethics. The study used a qualitative descriptive research step on the economic aspects of the culture of rural songket craftsmen in Pemulutan District, Ogan Ilir Regency. From this research, an overview of the environment in the West Pemulutan Sub-district has a strong social value, so that various activities include activities that increase the prevailing system values. Songket craftsmen, participating in participating, both invited to attend, were also invited to be active in every socio-cultural agenda in the countryside. This activity certainly has an influence on the allocation of time for their business activities as craftsmen both in the production and marketing processes, thus increasing production volume, number of sales, and relations with business relations. In general songket craftsmen have understood, pondered, and let down understanding, but they prioritized togetherness as villagers. The economy of songket craftsmen has stepped on the economy of capital with a pre-capital category, while some are still part of a subsistence economy (enough to meet minimal needs). Income can be increased to a more advanced capital economy with efficiency in transportation aspects and capital control aspects consisting of materials, as well as improving managerial aspects. Activities to maintain togetherness in the countryside, and activities to seek and improve finance are actions that bring benefits so that they can improve conformity with Islamic values. Meanwhile, the economic potential of songket is very large. Furthermore, songket craft activities need to be developed more optimally so that they become part of the road to achieve greater prosperity.

The plight of the cute little lambs: travel medicine’s role in animal welfare

ABSTRACTThe principles and aims of ecotourism are shared by a range of disciplines including health and medicine. Travel medicine’s involvement in One Health and also Responsible Travel provides the background for exploring these concepts’ core principle of interconnectedness and its application to destination well-being. The connection between human and animal health is usually represented one-directionally in zoonotic diseases; there is little evidence of reciprocal consideration. This lack is illustrated in a tourist activity, here the use of newborn lambs as photo motifs, vicarious for other animal uses in tourism. To understand the issue of animal welfare arising from this practice, it is necessary to appreciate a range of relevant perspectives, such as itinerant street work in Cusco, including presenting as photographic motif, as well as the consideration of tourism photography, photographer and motif. Furthermore, it is important to include the psychological context of human use of animals, and the different perspectives of animal ethics and welfare in tourism. The use of animals as photo props has implications for the owners’, animals’ and, to a lesser degree, tourists’ well-being. Local animal welfare should be included in travel health education to fulfil travel medicine’s obligations to One Health and Responsible Travel.

Camp stability predicts patterns of hunter-gatherer cooperation.

Humans regularly cooperate with non-kin, which has been theorized to require reciprocity between repeatedly interacting and trusting individuals. However, the role of repeated interactions has not previously been demonstrated in explaining real-world patterns of hunter–gatherer cooperation. Here we explore cooperation among the Agta, a population of Filipino hunter–gatherers, using data from both actual resource transfers and two experimental games across multiple camps. Patterns of cooperation vary greatly between camps and depend on socio-ecological context. Stable camps (with fewer changes in membership over time) were associated with greater reciprocal sharing, indicating that an increased likelihood of future interactions facilitates reciprocity. This is the first study reporting an association between reciprocal cooperation and hunter–gatherer band stability. Under conditions of low camp stability individuals still acquire resources from others, but do so via demand sharing (taking from others), rather than based on reciprocal considerations. Hunter–gatherer cooperation may either be characterized as reciprocity or demand sharing depending on socio-ecological conditions.

‘There’s No Such Thing as a Free Lunch’

Reciprocity has seen much less attention by Aegean archaeologists than other economic concepts such as redistribution, largely because of an assumption that reciprocity is characteristic of ‘egalitarian’ or less developed societies, as well as a related interest in political economies of more complex (palatial) societies, which are assumed to be characterized by redistribution. In Aegean archaeology, consideration of reciprocity is usually limited to gift exchange, either royal in the context of Late Bronze Age interactions with other societies in the eastern Mediterranean, or among elites in a Homeric model. Yet reciprocity has great potential to help us understand better the political economies and social organization of the Late Bronze Age Aegean. Reciprocity encompasses the social dynamics of any exchange between individuals and how these social relationships form the structure of social organization. Of particular interest here is how the standard categories of reciprocity—that is generalized (gift exchange), balanced (trade or immediate discharge of debt), and negative (one-sided benefit)—are manipulated through strategies such as competitive generosity and asymmetrical exchanges, leading to indebtedness of one exchange partner to the other; this can be institutionalized into hierarchical social structures. Feasting is one important category of exchange that can result in asymmetrical relationships and social inequality, and the Mycenaean evidence allows us to examine feasting in detail. Recent work in Linear B texts has suggested that palatial elites manipulated reciprocity through feasting as a strategy for maintaining social and political power. Likewise, elites utilized gifts of prestige items within their own polities to forge alliances and maintain social power

The Ecology of Father‐Child Relationships: An Expanded Model

We expand our 2007 heuristic model of father involvement using recent research on the dynamic and reciprocal processes by which fathers influence children's development over time. Based on new evidence, our expanded model incorporates more dynamic reciprocity, temporal factors, and nuanced considerations of context in which fathers parent. We identify aspects of context as well as fathers' personality and behavior that are central to the next generation of studies on fathers. We highlight studies related to fathering versus mothering, discuss ecological theory and how it has been used to understand fathering, and present an expanded version of our model.

Syndication Networks and Investment Activity in the Venture Capital Industry

The wide-spread use of syndication among venture capital investors has led to the creation of extensive co-investment networks which may in turn affect syndication and investment activity. Using an extensive ten year panel data set of 3,797 venture capital and 1,290 angel investors, this study finds that investors with more direct contacts, in particular with later stage investors, exhibit higher deal flow and faster extend their network. Linking syndication motives to certain network structures allows for inferring on the significance of syndication rationales. Accessing (complementary) resources appears to be the strongest incentive to syndicate, whereas deal sourcing and especially reciprocity considerations appear relatively weak syndication motives. Thereby, using syndicated financing to overcome resource constraints appears even more pivotal for early stage angel investors.

To Trust or Not to Trust That is Not the Question

We propose that there are three determinants of sender behavior in trust games: Beliefs re-garding the amounts returned, risk aversion, and reciprocity. Particularly, we are interested in the role of reciprocity because the possibility of negative expected reciprocal utility may lead to betrayal-averse sender behavior, i.e. to a situation where reciprocal subjects send less money than solely selfish ones. In our experiment, most subjects show distinct social preferences in the receiver role, but in the sender role they do not distinguish between a standard trust game with a human partner and a non-social, lottery-like setting, where a computer plays the role of the receiver. This means that the relevance of reciprocity considerations under uncertainty might be fundamentally different from those when no uncertainty is present. Furthermore, we find that sendings are mainly driven by overoptimistic beliefs. We use a modified version of the reciprocity model of Dufwenberg and Kirchsteiger [Games Econ. Beh. 47 (2004) 268] to explain our results and thereby show why reciprocal and selfish subjects almost do not differ in their sending behavior if one controls for beliefs and risk aversion. For other experimental settings, our model does predict differing behavior, which is in line with findings reported in the literature.
