We review and compare four broad categories of spatially-explicit modelling approaches currently used to understand and project changes in the distribution and productivity of living marine resources including: 1) statistical species distribution models, 2) physiology-based, biophysical models of single life stages or the whole life cycle of species, 3) food web models, and 4) end-to-end models. Single pressures are rare and, in the future, models must be able to examine multiple factors affecting living marine resources such as interactions between: i) climate-driven changes in temperature regimes and acidification, ii) reductions in water quality due to eutrophication, iii) the introduction of alien invasive species, and/or iv) (over-)exploitation by fisheries. Statistical (correlative) approaches can be used to detect historical patterns which may not be relevant in the future. Advancing predictive capacity of changes in distribution and productivity of living marine resources requires explicit modelling of biological and physical mechanisms. New formulations are needed which (depending on the question) will need to strive for more realism in ecophysiology and behaviour of individuals, life history strategies of species, as well as trophodynamic interactions occurring at different spatial scales. Coupling existing models (e.g. physical, biological, economic) is one avenue that has proven successful. However, fundamental advancements are needed to address key issues such as the adaptive capacity of species/groups and ecosystems. The continued development of end-to-end models (e.g., physics to fish to human sectors) will be critical if we hope to assess how multiple pressures may interact to cause changes in living marine resources including the ecological and economic costs and trade-offs of different spatial management strategies. Given the strengths and weaknesses of the various types of models reviewed here, confidence in projections of changes in the distribution and productivity of living marine resources will be increased by assessing model structural uncertainty through biological ensemble modelling.

Jean-Luc Marion’s phenomenology of giveness constitutes one of the most outstanding attempts to set up a universal theory of the phenomenologically given as a whole within the framework of contemporary philosophical thought. The aim of the present study is to apply the main categories of this phenomenological theory concerning gift to the singular type of phenomenon represented by the pure indeterminate and anonymous being to which Emmanuel Levinas refers by the name of il y a (“there is”) in his early writings (and also subsequently). Therefore, this concerns examining the multiple specific modes of giveness proper to the impersonal “there is” and also its paradoxical relationship both with the donor and with the receiver of such gift in order to show the possibility of a “third way” of phenomenological investigation. This is a way equally distant from the western traditional concept of Being as “stable presence” and from Levinas’ proposal geared to substitute ontology for ethics as “first philosophy”.

Objective
Scant evidence is available on the discordance between loneliness and social isolation among older adults. We aimed to investigate this discordance and any health implications that it may have.

Method
Using nationally representative datasets from ageing cohorts in Ireland (TILDA) and England (ELSA), we created a metric of discordance between loneliness and social isolation, to which we refer as Social Asymmetry. This metric was the categorised difference between standardised scores on a scale of loneliness and a scale of social isolation, giving categories of: Concordantly Lonely and Isolated, Discordant: Robust to Loneliness, or Discordant: Susceptible to Loneliness. We used regression and multilevel modelling to identify potential relationships between Social Asymmetry and cognitive outcomes.

Results
Social Asymmetry predicted cognitive outcomes cross-sectionally and at a two-year follow-up, such that Discordant: Robust to Loneliness individuals were superior performers, but we failed to find evidence for Social Asymmetry as a predictor of cognitive trajectory over time.

Conclusions
We present a new metric and preliminary evidence of a relationship with clinical outcomes. Further research validating this metric in different populations, and evaluating its relationship with other outcomes, is warranted.

It is important for young people to be able to read science-related media reports with discernment. ‘Getting Newswise’ was a research project designed to enable science and English teachers, working collaboratively, to equip pupils through the curriculum with critical reading skills appropriate for science news. Phase one of the study found that science and English teachers respond differently to science news articles and eight categories of critical response were identified. These findings informed phase two, in which classroom activities were devised whereby pupils examined, evaluated and responded to science-related news reports. Science-English collaboration had positive outcomes for pupil understanding

INTRODUCTION: The differential associations of beer, wine, and spirit consumption on cardiovascular risk found in observational studies may be confounded by diet. We described and compared dietary intake and diet quality according to alcoholic beverage preference in European elderly.

METHODS: From the Consortium on Health and Ageing: Network of Cohorts in Europe and the United States (CHANCES), seven European cohorts were included, i.e. four sub-cohorts from EPIC-Elderly, the SENECA Study, the Zutphen Elderly Study, and the Rotterdam Study. Harmonized data of 29,423 elderly participants from 14 European countries were analyzed. Baseline data on consumption of beer, wine, and spirits, and dietary intake were collected with questionnaires. Diet quality was assessed using the Healthy Diet Indicator (HDI). Intakes and scores across categories of alcoholic beverage preference (beer, wine, spirit, no preference, non-consumers) were adjusted for age, sex, socio-economic status, self-reported prevalent diseases, and lifestyle factors. Cohort-specific mean intakes and scores were calculated as well as weighted means combining all cohorts.

RESULTS: In 5 of 7 cohorts, persons with a wine preference formed the largest group. After multivariate adjustment, persons with a wine preference tended to have a higher HDI score and intake of healthy foods in most cohorts, but differences were small. The weighted estimates of all cohorts combined revealed that non-consumers had the highest fruit and vegetable intake, followed by wine consumers. Non-consumers and persons with no specific preference had a higher HDI score, spirit consumers the lowest. However, overall diet quality as measured by HDI did not differ greatly across alcoholic beverage preference categories.

DISCUSSION: This study using harmonized data from ~30,000 elderly from 14 European countries showed that, after multivariate adjustment, dietary habits and diet quality did not differ greatly according to alcoholic beverage preference.

This paper begins by outlining and critiquing what we term the dominant anglophone model of neo-liberal community safety and crime prevention. As an alternative to this influential but flawed model, a comparative analysis is provided of the different constitutional-legal settlements in each of the five jurisdictions across the UK and the Republic of Ireland (ROI), and their uneven institutionalization of community safety. In the light of this it is argued that the nature of the anglophone community safety enterprise is actually subject to significant variation. Summarizing the contours of this variation facilitates our articulation of some core dimensions of community safety. Then, making use of Colebatch’s (2002) deconstruction of policy activity into categories of authority and expertise, and Brunsson’s (2002) distinction between policy talk, decisions and action, we put forward a way of understanding policy activity that avoids the twin dangers of ‘false particularism’ and ‘false universalism’ (Edwards and Hughes, 2005); that indicates a path for further empirical enquiry to assess the ‘reality’ of policy convergence; and that enables the engagement of researchers with normative questions about where community safety should be heading.

This study revisits the effect of duration by residence in relation to smoking during pregnancy. It contributes to the literature by incorporating a health inequity perspective, and discusses whether immigrants tend to converge with Swedish women’s smoking. The study is based on Swedish Medical Birth Register and includes 1 1864 52 pregnancies between 1991 and 2012. Logistic regression was performed to attain crude and adjusted Odds Ratios and 95 % confidence intervals. Immigrants’ are divided by categorizing countries of origin depending on levels of Human Development (IHDI). Overall immigrant women show low levels of smoking during pregnancy when they arrive to Sweden, by duration of residence levels of smoking increase and converge with smoking patterns of Swedish women. I found that there are differences in smoking patterns depending on IHDI of the country. Immigrant women of higher categories of IHDI show higher levels of smoking although the increase of smoking is higher among immigrant women from categories of lower IHDI. However, immigrant women’s smoking during pregnancy is affected by duration of residence, and the increased smoking is associated with health inequalities related to their country of origins IHDI, and by socioeconomic inequalities in Sweden.

Aim Companies around the world are making sizeable investments into CSR initiatives, but ensuring appropriate returns on these investments remains challenging. Therefore, it is of value to study the communication of corporate CSR efforts. The purpose of this study is to investigate how consumers react to rational versus emotional message strategies in CSR communication. Two categories of consumer reactions were considered: trust and purchase intention. Methods Qualitative research with four focus groups was conducted. Participants discussed three texts regarding a CSR project, utilising a rational, emotional and a hybrid rational-emotional message strategy respectively. The conversations focused on trust towards the communication and purchase intention. Results Trust - All of the respondents viewed the rational text over the emotional text as more trustworthy, but they most positively reacted to the combined strategy. Rational information was viewed as more reliable by many participants, with emotional cues adding value by better holding their attention. Purchase intention – Participants more positively reacted to the rational CSR communication strategy, compared to an emotional strategy. For approximately half of respondents, the hybrid strategy targeting both rational and emotional cues was the most successful in terms of purchase intention. Upon further analysis, it was identified that this division in respondents’ opinions may reflect a gender difference, where men portrayed the more task oriented and women the socially sensitive consumers. Conclusions The findings support previous research championing the use of rational strategies over emotional strategies in CSR communication. A number of managerial implications that can be used by companies in order to better communicate their CSR activities and increase returns on CSR-related investments are provided.

Med begreppet "Internet of Things" menas att ett objekt ur den riktiga världen blir en del av internet. Tunabyggen i Borlänge planerar att implementera ett sådant informationssystem som med hjälp av sensorer och en ständig internetuppkoppling håller uppsikt över temperatur och luftfuktighet i utvalda lokaler. Det är ett enkelt system som till synes inte har så stora effekter på den nuvarande verksamheten. De ekonomiska effekterna går ofta att räkna på i förhand men effekterna på personal, miljö och rutiner kan glömmas bort. Vi har därför med detta examensarbete undersökt vilka inledande effekter som kan tänkas uppkomma efter implementering av ett nytt informationssystem med "Internet of Things" funktionalitet i en verksamhet. Detta sker inom kategorierna ekonomi, arbetsmiljö, miljöpåverkan och systemförvaltning. För att kunna besvara detta har vi gjort en fallstudie baserad på en scenariometodik som består av fyra faser. Fas 1, där vi fick vårt Case och skapade en förståelse för scenariofältet. Fas 2, där vi identifierade nyckelfaktorer. Detta har gjorts genom en litteraturstudie samt intervju med berörd personal på Tunabyggen. Fas 3, där analysen av dessa nyckelfaktorer skedde genom nulägesanalys och framtidsanalys av nyckelfaktorer. Fas 4, där vi genererade scenarier av de analyserade nyckelfaktorerna. Det har sedan gjorts en SWOT-analys för att belysa styrkor, svagheter, möjligheter och hot. Resultatet visar tydliga tecken på att det kommer att bli många effekter för Tunabyggen efter implementering av det nya informationssystemet som yttrar sig i alla kategorier. Slutsatsen är att vid implementation av ett informationssystem som detta är effekterna många. Detta är något som vi anser bör beaktas av alla verksamheter som har tankar på att införskaffa ett nytt informationssystem. De bör inte bara utvärdera informationssystem rent ekonomiskt utan borde ta i beaktning att det finns ett antal andra faktorer som har en avgörande roll om implementation av informationssystem ska bli lyckad.

Computer-based simulation games (CSG) are a form of innovation in learning and teaching. CGS are used more pervasively in various ways such as a class activity (formative exercises) and as part of summative assessments (Leemkuil and De Jong, 2012; Zantow et al., 2005). This study investigates the current and potential use of CGS in Worcester Business School’s (WBS) Business Management undergraduate programmes. The initial survey of off-the-shelf simulation reveals that there are various categories of simulations, with each offering varying levels of complexity and learning opportunities depending on the field of study. The findings suggest that whilst there is marginal adoption of the use CSG in learning and teaching, there is significant opportunity to increase the use of CSG in enhancing learning and learner achievement, especially in Level 5 modules. The use of CSG is situational and its adoption should be undertaken on a case-by-case basis. WBS can play a major role by creating an environment that encourages and supports the use of CSG as well as other forms of innovative learning and teaching methods. Thus the key recommendation involves providing module teams further support in embedding and integrating CSG into their modules.

Public policies have been studied in the various fields of humanities and social sciences, from different theoretical and technical aspects. However, there is still a lack of studies that incorporate the dimension that encompasses the political action and its interference in such actions, also recognizing the importance of the institutional setting of the Brazilian presidential model in implementing these policies. This fragmented and multiparty system has led to power heterogeneous sets of political parties. Thus, the ministerial offices, more than assisting the President´s government project, manage particularized agendas, which are party biased and have the influence of interest groups in hegemonic themes addressed by government agencies. When these agendas operate in sectoral and specialized policies, the friction level is apparently low. However, when this occurs in intersectoral actions, such as in regional development, there is evidence of strong signs of competition among government agencies, which in theory, should operate in an integrated manner. Although this is not a specific feature of Luiz Inacio Lula da Silva´s government- the period to be studied- there was similar behavior in Fernando Henrique Cardoso´s presidency, one realizes that the expansion of coalition on behalf of governance is increasingly interfering in the outcome of intersectoral public policies, due to these multiple arguments in action. In order to understand these processes, this study focused on the Sustainable and Integrated Development Programme for Differentiated Meso-Regions (PROMESO), part of the National Policy for Regional Development (NPRD). The program provides interface with various government agencies and their public policies in a clear intersectoral design. The research sought to identify and analyze the relationships between government agencies and their programs with interest groups, whether political parties or other segments of civil society, highlighting the logic of favoritism, which poses in second place the integration of actions in the intersectoral policies. Therefore, besides the theoretical debate that incorporates several categories of political science, public administration, public policy, geography and economics, the study focused on secondary sources, using different government agencies databases in order to raise information. It was observed that the interference of partisan politics has been disastrous for some public policies. Thus, the research confirms that cooperative character is fragile within government agencies, often limited to official documents, and that there is indeed, a striking feature of competition, especially when it comes to transversalized policies
