Adapting to Climate Change in Reindeer Herding: The Nation-State as Problem and Solution.

This paper discusses the role of nation-states and their systems of gover- nance as sources of barriers and solutions to adaptation to climate change from the point of view of Saami reindeer herders. The Saami, inhabiting the northernmost areas of Fennoscandia, is one of more than twenty ethnic groups in the circumpolar Arctic that base their traditional living on reindeer herding. Climate change is likely to affect the Saami regions severely, with winter temperatures predicted to increase by up to 7 centigrade. We argue that the pastoral practices of the Saami herders are inherently better suited to handle huge natural variation in climatic con- ditions than most other cultures. Indeed, the core of their pastoral practices and herding knowledge is skillful adaptation to unusually frequent and rapid change and variability. This paper argues that the key to handle permanent changes successfully is that herders themselves have sufficient degrees of freedom to act. Considering the similarities in herding practices in the fours nation-states between which Saami culture is now divided . Norway, Sweden, Finland, and Russia . the systems of governance are surprisingly different. Indeed, the very definition of what is required to be defined as an ethnic Saami is very different in the three Nordic countries. We argue that timely adjust- ments modifying the structures of governance will be key to the survival of the Saami reindeer herding culture. Since the differences in governance regimes . and the need to change national governance structures . are so central to our argument, we spend some time tracing the origins of these systems.

Demographic shocks: the view from history

The paper will basically deal with four issues. The first one puts current changes or shifts into a historical comparative perspective. The second deals with "traditional" shocks or violent disturbances of the system and their consequences. The third discusses the "seismic" changes experienced in the past, attempts their measurement, and exemplifies their effects on population and society. The fourth deals with the relevance that past experience has for current changes.Demography ; Economic conditions

Are Migrants Selected on Motivational Orientations? Selectivity Patterns amongst International Migrants in Europe

Migration scholars often assume migrants are the most ambitious and motivated individuals of their home countries. Yet research on motivational selectivity is scant. We present the first systematic cross-national analysis of migrants' selectivity on achievement-related motivational orientations (ARMOs). We measure ARMOs using a validated scale that combines orientations towards socio-economic success, risk, and money. Matching the European Social Survey and the World Value Survey cumulative data sets, we examine whether international migrants recently arrived in Europe are more achievement-oriented than those observational equivalents that do not migrate. We focus on migrants from nine different origins (France, Germany, the United Kingdom, Poland, Romania, Turkey, Morocco, Brazil, and Andean countries) sampled at different European destinations varying in gross domestic product, type of welfare state, and linguistic distance. Our findings seem to contradict the arguments about a common migrant personality put forward by social psychologists, as well as most of the predictions of standard economic models. We do find, however, some support for the welfare magnet hypothesis, as well as for the expectation that gender traditionalism favours negative selectivity of migrant women. We show that reported estimates are not driven by educational selectivity and are unlikely to be biased by destination effects.This study received financial support from the following two projects: Growth, Equal Opportunities, Migration, and Markets, GEMM, funded by the European Commission Horizon 2020 programme (ID 649255), and New Approaches to Immigration Research, NewAIR, funded by the Spanish Ministry of Economy and Competitiveness (CSO2016-78452)

Evolution of genetic networks for human creativity

The genetic basis for the emergence of creativity in modern humans remains a mystery despite sequencing the genomes of chimpanzees and Neanderthals, our closest hominid relatives. Data-driven methods allowed us to uncover networks of genes distinguishing the three major systems of modern human personality and adaptability: emotional reactivity, self-control, and self-awareness. Now we have identified which of these genes are present in chimpanzees and Neanderthals. We replicated our findings in separate analyses of three high-coverage genomes of Neanderthals. We found that Neanderthals had nearly the same genes for emotional reactivity as chimpanzees, and they were intermediate between modern humans and chimpanzees in their numbers of genes for both self-control and self-awareness. 95% of the 267 genes we found only in modern humans were not protein-coding, including many long-non-coding RNAs in the self-awareness network. These genes may have arisen by positive selection for the characteristics of human well-being and behavioral modernity, including creativity, prosocial behavior, and healthy longevity. The genes that cluster in association with those found only in modern humans are over-expressed in brain regions involved in human self-awareness and creativity, including late-myelinating and phylogenetically recent regions of neocortex for autobiographical memory in frontal, parietal, and temporal regions, as well as related components of cortico-thalamo-ponto-cerebellar-cortical and cortico-striato-cortical loops. We conclude that modern humans have more than 200 unique non-protein-coding genes regulating co-expression of many more proteincoding genes in coordinated networks that underlie their capacities for self-awareness, creativity, prosocial behavior, and healthy longevity, which are not found in chimpanzees or Neanderthals

FREE ORAL COMMUNICATIONS 2: ALCOHOL AND LIVER—CLINICAL RESEARCHO2.1RAPID DECLINE OF LIVER STIFFNESS WITH ALCOHOL WITHDRAWAL IN HEAVY DRINKERS

Background and aims. Measurement of liver stiffness using real-time elastography appears as a promising tool to evaluate the severity of chronic liver diseases. Previous studies in patients with alcoholic liver disease have suggested that fibrosis was the only histological parameter to influence liver stiffness. To challenge this hypothesis, we have prospectively tested the short-term impact of alcohol withdrawal on liver stiffness value. Methods. All patients hospitalized for alcohol withdrawal in our Liver Unit between September 2008 and December 2010 had a liver stiffness determination (using a FibroScan® device) at entry (D0) and 7 days after alcohol withdrawal (D7). Stiffness values were compared using non-parametric test for paired-values. We compared (i) the 10 measures performed at D0 and at D7 for each patient; (ii) the variation of the median result of all patients (using Wilcoxon test in both cases). Results. A total of 138 patients were included in the study [median alcohol consumption: 150g/day (range: 40-400); hepatitis C: n=22 (15.9%); cirrhosis: n=29 (21.0%)]. From D0 to D7, the liver stiffness decreased significantly in 61 patients (44.2%) and increased significantly in 18 (13.0%). Considering all patients, median liver stiffness value decreased from 7.25 to kPa (P<0.001). The stage of fibrosis indicated by liver stiffness changed in 47 patients between D0 and D7 (decrease in 33 and increase in 14). Conclusion. Liver stiffness decreases significantly in nearly half of alcoholic patients after only 7 days of abstinence. This result strongly suggests that non-fibrotic lesions (such as inflammatory ones) may influence liver stiffness. From a practical point of view, it also shows that variation in alcohol consumption must be taken into account for the interpretation of liver stiffness valu

Value stability and change during self-chosen life transitions: Self-selection versus socialization effects

Copyright @ 2013 APA. This article may not exactly replicate the final version published in the APA journal. It is not the copy of record.Three longitudinal studies examine a fundamental question regarding adjustment of personal values to self-chosen life transitions: Do values fit the new life setting already at its onset, implying value-based self-selection? Or do values change to better fit the appropriate and desirable values in the setting, implying value socialization? As people are likely to choose a life transition partly based on their values, their values may fit the new life situation already at its onset, leaving little need for value socialization. However, we propose that this may vary as a function of the extent of change the life transition entails, with greater change requiring more value socialization. To enable generalization, we used 3 longitudinal studies spanning 3 different life transitions and different extents of life changes: vocational training (of new police recruits), education (psychology vs. business students), and migration (from Poland to Britain). Although each life transition involved different key values and different populations, across all 3 studies we found value fit to the life situation already early in the transition. Value socialization became more evident the more aspects of life changed as part of the transition, that is, in the migration transition. The discussion focuses on the implications of these findings for research on values and personality change, as well as limitations and future directions for research

Prenatal and Postnatal Parental Behavior in the Context of Infant Regulation

Following the notion that parenting starts with pregnancy (Glover & Capron, 2017), the current dissertation investigated how early parenting is shaped and how it relates to infant regulation, thereby taking a longitudinal perspective. Based on a systematic review and the data from the longitudinal study, the Bremen Initiative to Foster Early Childhood Development (BRISE) on the development of socially and/or culturally disadvantaged families, this dissertation focuses on two main research questions: (1) How does parenting emerge and develop from pregnancy to early infancy? (2) How are early parenting and infant regulation related? The first publication provides a systematic literature review of 107 studies in total. It summarizes what is already known about the relation between parenting and infant regulation in the first two years of life. Corresponding analyses suggested that semi-structured measures seem best suitable to measure infant regulation during the first year and that structured measures seem better at probing self-regulation in older children. Parental reports were less likely to capture the positive relation between parental behavior and infant regulation when compared to structured and semi-structured methods. Most studies assessed the predictive role of parental behavior on infant regulation and revealed a stronger association than vice versa. Directions for future research were discussed by means of the shortcomings of the studies included in the systematic review, such as the need to examine the role of negative parenting, considering the role of fathers, and taking into account demographic information. The second publication focused on the emergence of parenthood longitudinally. More specifically, (a) the development of maternal self-efficacy - a precursor of early parenting - was investigated from pregnancy to the postnatal period, and (b) the role of demographic factors together with formal and informal support during pregnancy were studied in their predictive value for maternal self-efficacy three months after birth. Results revealed that maternal self-efficacy increased rapidly from the prenatal to the postnatal period. Mothers with previous birth experience, lower levels of education, those who were born outside of Germany, as well as mothers with higher levels of formal and informal social support during pregnancy all showed higher levels of maternal self-efficacy three months after birth. Moreover, first-time mothers and mothers born in Germany benefited more from formal support than mothers with previous experience and mothers born outside of Germany. These findings underline the need for early intervention programs for expectant mothers during the prenatal phase. Lastly, the third publication focused on the postnatal period, examining the influence of maternal self-efficacy at three months after birth on infant regulation at three and seven months, and the role of maternal soothing behavior in order to explain this relationship. Infant crying and sleeping behavior, as well as parental close and distant soothing strategies were of special interest. Findings indicated that (a) infant regulatory behavior was quite stable across measurement points; (b) mothers with higher self-efficacy regarding parenting used more close soothing strategies, and that (c) soothing strategies directly influenced and maternal self-efficacy indirectly influenced infant crying and sleeping behaviors. These findings point out that sensitive and adequate parental practices promote better infant regulation in terms of crying and sleeping. Altogether, the studies revealed positive associations between early parental practices and infant regulation during the first two years of life, thus underscoring the need to support mothers as early as possible, especially mothers from socially and/or culturally disadvantaged populations
