The Impact

Current crustacean production (~14 Mt) and value (up to USD60 billion) is significant and likely to increase further during the twenty-first century. Satisfactory management and handling of live crustaceans are important to safeguard the value, security, safety, and sustainability of wild-caught and aquaculture-sourced fisheries and increasingly to foster improved welfare and public perception of both industries. Decapod crustaceans are frequently transported live and internationally over long distances and experience anthropogenic stressors from point of capture to point of sale. Physical handling, emersion in air, and temperature fluctuations are key examples of stressors, which elicit progressive behavioral, physiological, and immunological stress responses in crustaceans. Stress responses are initiated to return the individual to a state of homeostasis; if these fail, then physiological collapse, a loss of vitality, and death will likely occur. There are several ways to mitigate the impact of stressors, reduce associated stress responses, and thus maintain quantity (survival, weight) and quality (vitality, sensorial perception) of live crustaceans. These include improved fishing techniques, better handling and operating procedures, and the introduction of proven equipment and facilities during the supply chain. The action of stressors and the effectiveness of potential mitigating strategies have been studied intensively via behavioral analysis and hemolymph sampling to ascertain changes in metabolites and the immune system. Finally, improved handling and management include global and ethical considerations, supported by relevant research, which may be achieved by adopting best practices and standards and by ensuring welfare and disease regulations.

The Impact

The ethics of invertebrate research have largely been ignored compared to the consideration of higher order animals, but more recent focus has questioned this trend. Using biohybrid robotic jellyfish as a case study, we examine the ethical considerations of invertebrate work and provide recommendations for future guidelines. This paper starts with an overview of philosophical views of animal ethics, the current state of knowledge for invertebrate pain and nociception, and current ethical guidelines. Next, we delve into the case study and analogous precedents. Specifically, in prior studies, we developed biohybrid robotic jellyfish, which modified live moon jellyfish with microelectronic swim controllers for future applications in ocean monitoring. Although jellyfish possess no central nervous system, pain receptors, or nociceptors, we closely monitored their stress responses, using the precautionary and minimization principles in consideration of the 4Rs: reduction, replacement, refinement, and reproducibility. We also discuss ethical considerations related to our studies and suggest that public opinion of invertebrate research relies heavily on repugnance, including fears of ‘playing God’ or limiting the ‘free will’ of animals. These issues are also examined for prior bioethics cases, such as the RoboRoach, cyborg beetle, ‘microslavery’ of microbes, biohybrid robots incorporating tissues from sea slugs (which are known to possess nociceptors), and other tissue cutting experiments involving soft-bodied invertebrates. However, biohybrid robotic jellyfish pose further ethical questions of potential ecological consequences as ocean monitoring tools, such as the impact of electronic waste in the ocean. To conclude these evaluations, we recommend that publishers require brief ethical statements for invertebrate research, which can include the following: a scientific justification for the research, discussion of the 4Rs, and cost-benefit analysis. We also delineate the need for more research on pain and nociception in invertebrates, which can then be used to revise or validate current research standards. These actions provide a stronger basis for the ethical study of invertebrate species, with implications for individual, species-wide, and ecological impacts on animals, as well as for interdisciplinary studies in science, engineering, and philosophy.

the article defines the basic concepts in the field of mass media research. It is noted that the research of mass communications is presented in the scientific and educational literature by a wide range of author’s positions on its structuring depending on the choice of features and priorities for the selection of structural elements. It is pointed out that the study of mass communication in Western countries is developing essentially as a single research complex with a focus on managerial, ideological and cultural aspects of com- municative influence on man and society. It is noted that there are three relatively independent areas of research: 1) non-verbal analysis of rationality in the «production of culture», with emphasis on the organization of mass media and ensuring a level of professionalism and sales in a competitive environment. 2) Neo-Marxist approach, with the study of the symbolic aspect of ideological coercion and political hegemony. 3) Neo-Durkheimian studies of «public perception», which focus on the formation by the mass media of collective ideas of a sense of solidarity of individuals as members of mass audiences. It is emphasized that the basis for the differentiation of approaches to the study of mass communication in society is the relationship between the role of spiritual and material factors. It is pointed out that on the one hand, culturological approaches are widespread, which focus on the study of mass communication in the context of ideas, values, ideas that are both produced and disseminated by them in society. On the other hand, the influential tradition of analysis of mass communication sharpens attention to the study of the structure of property relations, the peculiarities of the imple-mentation of market relations in the field of mass communication. The impact on the media of the achievements of scientific and technological progress, which significantly change their nature, expand their functions in the following areas: 1) decentralization - the choice of programs increasingly depends on the individual, 2)increasing the volume of information programs, 3) the possibility of interactivity - interaction communication for information exchange

The Impact

New ways of doing research are needed to tackle the deep interconnected nature of twenty first century challenges, like climate change, obesity, and entrenched social and economic inequalities. While the impact agenda has been shaping research culture, this has largely been driven by economic imperatives, leading to a range of negative unintended consequences. Alternative approaches are needed to engage researchers in the pursuit of global challenges, but little is known about the role of impact in research cultures, how more or less healthy “impact cultures” might be characterized, or the factors that shape these cultures. We therefore develop a definition, conceptual framework, and typology to explain how different types of impact culture develop and how these cultures may be transformed to empower researchers to co-produce research and action that can tackle societal challenges with relevant stakeholders and publics. A new way of thinking about impact culture is needed to support more societally relevant research. We propose that healthy impact cultures are: (i) based on rigorous, ethical, and action-oriented research; (ii) underpinned by the individual and shared purpose, identities, and values of researchers who create meaning together as they generate impact from their work; (iii) facilitate multiple impact sub-cultures to develop among complementary communities of researchers and stakeholders, which are porous and dynamic, enabling these communities to work together where their needs and interests intersect, as they build trust and connection and attend to the role of social norms and power; and (iv) enabled with sufficient capacity, including skills, resources, leadership, strategic, and learning capacity. Based on this framework we identify four types of culture: corporate impact culture; research “and impact” culture; individualistic impact culture; and co-productive impact culture. We conclude by arguing for a bottom-up transformation of research culture, moving away from the top-down strategies and plans of corporate impact cultures, toward change driven by researchers and stakeholders themselves in more co-productive and participatory impact cultures that can address twenty first century challenges.

This article has two purposes: (a) to examine the relationship between intercultural power relations and the widespread practice of accent discrimination and (b) to underscore the ramifications of accent discrimination both for the individual and for global society as a whole. First, authors review social theory regarding language and group identity construction, and then go on to integrate more current studies linking accent bias to sociocultural variables. Authors discuss three examples of intercultural accent discrimination in order to illustrate how this link manifests itself in the broader context of international relations (i.e., how accent discrimination is generated in situations of unequal power) and, using a review of current research, assess the consequences of accent discrimination for the individual. Finally, the article highlights the impact that linguistic discrimination is having on linguistic diversity globally, partially using data from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and partially by offering a potential context for interpreting the emergence of practices that seek to reduce or modify speaker accents.

Abstract. Our unit investigates the relationship of emotional processes (experience, expression, and coping), their physiological correlates and possible health outcomes. We study domain specific anger expression behavior and associated cardio-vascular loads and found e.g. that particularly an open anger expression at work is associated with greater blood pressure. Furthermore, we demonstrated that women may be predisposed for the development of certain mental disorders because of their higher disgust sensitivity. We also pointed out that the suppression of negative emotions leads to increased physiological stress responses which results in a higher risk for cardiovascular diseases. We could show that relaxation as well as music activity like singing in a choir causes increases in the local immune parameter immunoglobuline A. Finally, we are investigating connections between migrants’ strategy of acculturation and health and found e.g. elevated cardiovascular stress responses in migrants when they where highly adapted to the German culture.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.

The Impact

Childbirth has been identified as a possible traumatic experience, leading to traumatic stress responses and even to the development of posttraumatic stress disorder (PTSD). The current study investigated the psychometric properties of the Dutch version of the Impact of Event Scale-Revised (IES-R) in a group of women who recently gave birth (N = 435). In addition, a comparison was made between the original IES and the IES-R. The scale showed high internal consistency (α = 0.88). Using confirmatory factor analysis no support was found for a three-factor structure of an intrusion, an avoidance, and a hyperarousal factor. Goodness of fit was only reasonable, even after fitting one intrusion item on the hyperarousal scale. The IES-R correlated significantly with scores on depression and anxiety self-rating scales, as well as with scores on a self-rating scale of posttraumatic stress disorder. Although the IES-R can be used for studying posttraumatic stress reactions in women who recently gave birth, the original IES proved to be a better instrument compared to the IES-R. It is concluded that adding the hyperarousal scale to the IES-R did not make the scale stronger.

This study aims at understanding how the perceptions about migrants have been created and transferred into daily life as a stigmatization by means of public perception, media and state law implementations.  The focus would be briefly what kind of consequences these perceptions and stigmatization might lead. First section will examine the background of migration to Turkey briefly and make a summary of migration towards Turkey by 90s. Second section will briefly evaluate the preferential legal framework, which constitutes the base for official discourse differentiating the migrants and implementations of security forces that can be described as discriminatory. The third section deals with the impact of perceptions influential in both formation and reproduction of inclusive and exclusive practices towards migrant women. Additionally, impact of public perception in classifying the migrants and migratory processes would be dealt in this section.

Levels Of Support

Existing research has consistently shown that perceptions of the potential economic consequences of Scottish independence are vital to levels of support for constitutional change. This paper attempts to investigate the mechanism by which expectations of the economic consequences of independence are formed. A hypothesised causal micro-level mechanism is tested that relates constitutional preferences to the existing skill investments of the individual. Evidence is presented that larger skill investments are associated with a greater likelihood of perceiving economic threats from independence. Additionally, greater perceived threat results in lower support for independence. The impact of uncertainty on both positive and negative economic expectations is also examined. While uncertainty has little effect on negative expectations, it significantly reduces the likelihood of those with positive expectations supporting independence. Overall, it appears that a general economy-wide threat is most significant, and it is conjectured that this stems a lack of information on macroeconomic governance credentials.
