Being optimally aroused matters: Effects of a weak stress manipulation on children’s executive functions are moderated by temperament and age

We tested a core assumption of the bidirectional model of executive function (EF) (Blair & Ursache, 2011) indicating that EF is dependent on arousal. From a bottom-up perspective the performance on EF tasks is assumed to be curvilinearly related to arousal, with very high or low levels of arousal impairing EF. N = 107 4-and 6-year-olds’ performance on EF tasks was explored as a function of a weak stress manipulation aiming to raise children’s emotional arousal. EF (Stroop, Flanker, Go/no-go, and Backwards Color Recall) was assessed and stress was induced in half of the children by imposing a mild social evaluative threat. Furthermore, children’s temperament was assessed as a potential moderator. We found that stress effects on children’s EF performance were moderated by age and temperament: 4-year-olds with high Inhibitory Control and high Attentional Focusing were negatively affected by the stressor. However, it is unclear whether these effects were mediated by self-reported arousal. Our findings disconfirmed the hypotheses that adverse effects of the stressor are particularly high in children high on emotional reactivity aspects of temperament and low on self-regulatory aspects of temperament. Further, 6-year-olds did not show any stress effects. Results will be discussed within the framework of the Yerkes-Dodson law and with regard to stress manipulations in children.

Self-initiated expatriates and their career success

Purpose This paper aims to provide conceptual clarity by distinguishing self‐initiated expatriates (SIEs) from company‐assigned expatriates (AEs), and skilled migrants; most importantly, it introduces an overarching conceptual framework based on career capital theory to explain SIEs’ career success. Design/methodology/approach This conceptual framework is based on a review of the relevant literature on SIE, expatriation, career studies, cross‐cultural studies, migration, and other related areas. Findings Protean career attitude, career networks, and cultural intelligence are identified as three major types of career capital influencing SIEs career success positively; the predicting relationships between these are mediated by cultural adjustment in the host country. Cultural distance acts as the moderator, which highlights the influence of macro‐contextual factors on SIEs’ career development. Research limitations/implications The current paper applied career capital theory and did not integrate the impact of family and labour market situation on SIEs’ career development. Further research should test the proposed framework empirically, and integrate the impact of family‐ and career‐related factors into a holistic approach. Practical implications When constructing international talent acquisition and retention strategies, organizations and receiving countries should understand the different career development needs and provide SIEs with opportunities to increase career capital during expatriation. Furthermore, the current framework suggests how to adjust to the host country in order to meet career development goals. Originality/value The multi‐level and sequential framework adds value by identifying specific types of career capital for SIEs and providing a conceptual underpinning for explaining how they interact and foster SIEs’ career success. Moreover, the framework embraces SIEs from both developed and developing economies.

Vulnerabilitäts- und Resilienzfaktoren in der Psychopathologie und deren Einfluss im Umgang mit Stressoren: drei empirische Artikel als Beitrag zum erweiterten Verständnis des Vulnerabilität-Resilienz Modells

Das Vulnerabilität-Resilienz Modell dient in der folgenden Arbeit als theoretischer Rahmen, um die Entstehung von Psychopathologie zu verstehen. Es handelt sich um ein Schwellenmodell, bei dem angenommen wird, dass Vulnerabilitäts- und Resilienzfaktoren die Schwelle bestimmen, ab der ein Individuum unter Belastung (Stress) eine psychische Störung entwickelt. In dieser Arbeit werden unterschiedliche Vulnerabilitätsfaktoren (Emotionsregulation, Schmerz) sowie Resilienzfaktoren (Selbstwirksamkeit, soziale Unterstützung) bei unterschiedlichen Stichproben und Designs untersucht und in Form von drei veröffentlichten Artikeln präsentiert. Im ersten Artikel wurde ein Screening-Fragebogen (RS-8), welcher Rumination und Suppression erfasst, validiert. Die Resultate zeigen, dass der RS-8 ein valides, reliables und ökonomisches Messinstrument ist, welches bei klinischen und nicht-klinischen Stichproben eingesetzt werden kann. Im zweiten Artikel wurde in einem längsschnittlichen Design untersucht, welchen Einfluss Selbstwirksamkeit und soziale Unterstützung auf die Beziehung zwischen Schmerz und Depressivität bei Unfallpatienten haben. Die Resultate ergaben, dass Schmerz und soziale Unterstützung signifikante Prädiktoren für Depressivität darstellten. Selbstwirksamkeit wirkte als Moderator zwischen Schmerz und Depressivität. Tiefere Selbstwirksamkeit in Zusammenhang mit Schmerz hatte einen stärkeren Einfluss auf die Depressivität als höhere Selbstwirksamkeit und Schmerz. Die Resultate weisen darauf hin, dass Selbstwirksamkeit im Umgang mit Schmerz und in der Entwicklung von Depression zentral ist. Im dritten Artikel wurde der Zusammenhang zwischen kompensatorischem Gesundheitsverhalten (z.B. langsamer fahren) und Selbstwirksamkeit bei Fahrradfahrern, welche einen Fahrradhelm entweder gelegentlich oder nie trugen, untersucht. Die Resultate ergaben eine signifikante Interaktion zwischen Selbstwirksamkeit und der Häufigkeit des Fahrradhelmtragens auf das kompensatorische Gesundheitsverhalten. Individuen, die gelegentlich einen Fahrradhelm trugen und hohe Selbstwirksamkeit aufwiesen, zeigten mehr kompensatorisches Gesundheitsverhalten als jene mit tiefer Selbstwirksamkeit. Eine mögliche Erklärung könnte sein, dass bei den gelegentlichen Helmträgern eine höhere Risikowahrnehmung vorhanden ist. Die Ergebnisse dieser drei Artikel belegen die Relevanz von Vulnerabilitäts-und Resilienzfaktoren in klinischen und nicht-klinischen Stichproben.

Bedeutung der Arbeitsallianz in der Psychotherapie

Das pantheoretische Konzept der Arbeitsallianz stellt die kollaborative Qualität der an der Therapie beteiligten Personen (i. e. zumeist der Patient und der Therapeut) in den Mittelpunkt. Die Arbeitsallianz ist die weltweit am besten untersuchte Prozessvariable in der Psychotherapie. Die vorliegende Arbeit bietet einen Überblick über den aktuellen metaanalytischen Wissensstand. Basierend auf 200 Primärstudien mit 14.000 teilnehmenden Patienten wurde der Zusammenhang zwischen Arbeitsallianz und Therapieerfolg metaanalytisch untersucht. Die Arbeitsallianz erweist sich als äußerst robuster Prädiktor, der moderate 8 % der Varianz des Therapieerfolgs erklärt. Der Zusammenhang über die verschiedenen Psychotherapietraditionen hinweg zeigte sich sowohl unter randomisierten kontrollierten, manualisierten Studienbedingungen als auch unter naturalistischen Voraussetzungen. Der Effekt fand sich zudem in den störungsspezifischen Erfolgseinschätzungen und den generelleren Erfolgsmaßen. Die moderaten Therapeuteneffekte in den Primärstudien konnten metaanalytisch bestätigt werden. Soziokulturelle Aspekte wie Substanzmissbrauch und ethnische Minoritäten moderieren den Einfluss zwischen Arbeitsallianz und Therapieerfolg. Die Nähe der Forscher zum Allianzkonzept („allegiance“) beeinflusst die Vorhersagekraft der frühen Allianz zwar statistisch bedeutsam, jedoch nicht substanziell.

Snow shielding factors for cosmogenic nuclide dating inferred from long-term neutron detector monitoring

The depth-dependent attenuation of the secondary cosmic-ray particle flux due to snow cover and its effects on production rates of cosmogenic nuclides constitutes a potential source of uncertainty for studies conducted in regions characterized by frequent seasonal snow burial. Recent experimental and numerical modelling studies have yielded new constraints on the effect of hydrogen-rich media on the production rates of cosmogenic nuclides by low- and high-energy neutrons (<10(-3) MeV and >10(2) MeV, respectively). Here we present long-term neutron-detector monitoring data from a natural setting that we use to quantify the effect of snow cover on the attenuation of fast neutrons (0.1-10 MeV), which are responsible for the production of Ne-21 from Mg and Cl-36 from K. We use data measured between July 2001 and May 2008 at seven stations located throughout the Ecrins-Pelvoux massif (French Western Alps) and its surroundings, at elevations ranging from 200 to 2500 m a.s.l. From the cosmic-ray fluxes recorded during summer, when snow is absent, we infer an apparent attenuation length of 148 g cm(-2) in the atmosphere at a latitude of similar to 45 degrees N and for altitudes ranging from similar to 200 to 2500 m a.s.l. Using snow water-equivalent (SWE) values obtained through snow-coring campaigns that overlap in time the neutron monitoring for five stations, we show that fast neutrons are much more strongly attenuated in snow than predicted by a conventional mass-shielding formulation and the attenuation length estimated in the atmosphere. We suggest that such strong attenuation results from boundary effects at the atmosphere/snow interface induced by the high efficiency of water as a neutron moderator. Finally, we propose an empirical model that allows calculating snow-shielding correction factors as a function of SWE for studies using Ne-21 and Cl-36 analyses in Mg- and K-rich minerals, respectively. This empirical model is of interest for studies with a focus on cosmic-ray exposure dating, particularly if the target rocks are made up of mafic to ultramafic units where seasonal snow-cover is a common phenomenon.

Early Improvement As a Predictor of Later Response to Antipsychotics in Schizophrenia: A Diagnostic Test Review

OBJECTIVE How long clinicians should wait before considering an antipsychotic ineffective and changing treatment in schizophrenia is an unresolved clinical question. Guidelines differ substantially in this regard. The authors conducted a diagnostic test meta-analysis using mostly individual patient data to assess whether lack of improvement at week 2 predicts later nonresponse. METHOD The search included EMBASE, MEDLINE, BIOSIS, PsycINFO, Cochrane Library, CINAHL, and reference lists of relevant articles, supplemented by requests to authors of all relevant studies. The main outcome was prediction of nonresponse, defined as <50% reduction in total score on either the Positive and Negative Syndrome Scale (PANSS) or Brief Psychiatric Rating Scale (BPRS) (corresponding to at least much improved) from baseline to endpoint (4-12 weeks), by <20% PANSS or BPRS improvement (corresponding to less than minimally improved) at week 2. Secondary outcomes were absent cross-sectional symptomatic remission and <20% PANSS or BPRS reduction at endpoint. Potential moderator variables were examined by meta-regression. RESULTS In 34 studies (N=9,460) a <20% PANSS or BPRS reduction at week 2 predicted nonresponse at endpoint with a specificity of 86% and a positive predictive value (PPV) of 90%. Using data for observed cases (specificity=86%, PPV=85%) or lack of remission (specificity=77%, PPV=88%) yielded similar results. Conversely, using the definition of <20% reduction at endpoint yielded worse results (specificity=70%, PPV=55%). The test specificity was significantly moderated by a trial duration of <6 weeks, higher baseline illness severity, and shorter illness duration. CONCLUSIONS Patients not even minimally improved by week 2 of antipsychotic treatment are unlikely to respond later and may benefit from a treatment change.

Livelihood and Community Development: LforS learning and simulation game

Up to 15 people can participate in the game, which is supervised by a moderator. Households consisting of 1-5 people discuss options for diversification of household strategies. Aim of the game: By devising appropriate strategies, households seek to stand up to various types of events while improving their economic and social situation and, at the same time, taking account of ecological conditions. The annual General Community Meeting (GCM) provides an opportunity for households to create a general set-up at the local level that is more or less favourable to the strategies they are pursuing. The development of a community investment strategy, to be implemented by the GCM, and successful coordination between households will allow players to optimise their investments at the household level. The household who owns the most assets at the end of the game wins. Players participate very actively, as the game stimulates lively and interesting discussions. They find themselves confronted with different types of decision-making related to the reality of their daily lives. They explore different ways to model their own household strategies and discuss risks and opportunities. Reflections on the course of the game continually refer to the real-life situations of the participants.

CONMICOM – conflict mitigation in communities: LforS learning and simulation game

Three extended families live around a lake. One family are rice farmers, the second family are vegetable farmers, and the third are a family of livestock herders. All of them depend on the use of lake water for their production, and all of them need large quantities of water. All are dependent on the use of the lake water to secure their livelihood. In the game, the families are represented by their councils of elders. Each of the councils has to find means and ways to increase production in order to keep up with the growth of its family and their demands. This puts more and more pressure on the water resources, increasing the risk of overuse. Conflicts over water are about to emerge between the families. Each council of elders must try to pursue its families interests, while at the same time preventing excessive pressure on the water resources. Once a council of elders is no longer able to meet the needs of its family, it is excluded from the game. Will the parties cooperate or compete? To face the challenge of balancing economic well-being, sustainable resource management, and individual and collective interests, the three parties have a set of options for action at hand. These include power play to safeguard their own interests, communication and cooperation to negotiate with neighbours, and searching for alternatives to reduce pressure on existing water resources. During the game the players can experience how tensions may arise, increase and finally escalate. They realise what impact power play has and how alliances form, and the importance of trust-building measures, consensus and cooperation. From the insights gained, important conflict prevention and mitigation measures are derived in a debriefing session. The game is facilitated by a moderator, and lasts for 3-4 hours. Aim of the game: Each family pursues the objective of serving its own interests and securing its position through appropriate strategies and skilful negotiation, while at the same time optimising use of the water resources in a way that prevents their degradation. The end of the game is open. While the game may end by one or two families dropping out because they can no longer secure their subsistence, it is also possible that the three families succeed in creating a situation that allows them to meet their own needs as well as the requirements for sustainable water use in the long term. Learning objectives The game demonstrates how tension builds up, increases, and finally escalates; it shows how power positions work and alliances are formed; and it enables the players to experience the great significance of mutual agreement and cooperation. During the game and particularly during the debriefing and evaluation session it is important to link experiences made during the game to the players’ real-life experiences, and to discuss these links in the group. The resulting insights will provide a basis for deducing important conflict prevention and transformation measures.

Association of Trait Resilience With Peritraumatic and Posttraumatic Stress in Patients With Myocardial Infarction.

OBJECTIVE Acute myocardial infarction (MI) is a life-threatening condition, leading to immediate fear and distress in many patients. Approximately 18% of patients develop posttraumatic stress disorder in the aftermath of MI. Trait resilience has shown to be a protective factor for the development of posttraumatic stress disorder. However, whether this buffering effect has already an impact on peritraumatic distress and applies to patients with MI is elusive. METHODS We investigated 98 consecutive patients with acute MI within 48 hours after having reached stable circulatory conditions and 3 months thereafter. Peritraumatic distress was assessed retrospectively with three single-item questions about pain, fear, and helplessness during MI. All patients completed the Posttraumatic Diagnostic Scale (PDS) and the Resilience Scale to self-rate posttraumatic stress and trait resilience. RESULTS Multivariate models adjusting for sociodemographic and medical factors showed that trait resilience was not associated with peritraumatic distress, but significantly so with posttraumatic stress. Patients with greater trait resilience showed lower PDS scores (b = -0.06, p < .001). There was no significant relationship between peritraumatic distress scores and PDS scores; resilience did not emerge as a moderator of this relationship. CONCLUSIONS The findings suggest that trait resilience does not buffer the perception of acute MI as stressful per se but may enhance better coping with the traumatic experience in the longer term, thus preventing the development of MI-associated posttraumatic stress. Trait resilience may play an important role in posttraumatic stress symptoms triggered by medical diseases such as acute MI.

“Proximising” climate change reconsidered: A construal level theory perspective

Reducing the psychological distance of climate change has repeatedly been proposed as one strategy to increase individuals' motivation to respond to climate change. From the perspective of construal level theory, decreasing psychological distance should not itself influence people's willingness to act but change the processes that underlie individual decision-making. We conducted two experiments in which we manipulated the psychological distance of climate change. We found that participants with a distant focus relied more on scepticism to represent risks and make decisions about supporting climate change, whereas participants with a proximal perspective relied more on fear when making such judgements. However, the predicted Fear × Distance interaction was only found when self-reported fear rather than experimentally manipulated fear was used as a moderator. Our results suggest that simply proximising won't increase engagement and call for a more differentiated perspective on the effects of psychological distance in the context of climate change.
