Acculturation strategies among ethnic minority workers and the role of intercultural personality traits

International audienceIn an increasingly diverse work context minority employees strive to place and define themselves in terms of work and cultural identities. Based on Berry's acculturation model (1990), we defined and tested preferred acculturation strategies at work. It was predicted that , reflecting strong cultural identity maintenance combined with strong team identity adoption, is the most preferred strategy at work. The present study among non-Dutch employees working in The Netherlands ( = 108) showed that the dual identity is indeed preferred over strong team identity adoption, but solely among minority members who are emotionally stable. It is argued that these people are competent in dealing with the extra conflict and diversity-related stress that this acculturation strategy produces

Is virtual reality a valid tool for restorative environments research?

This study examines the validity of virtual reality for assessing the restorative quality of environments. In Study 1, participants (N = 23) visited a real natural and a real urban environment, after completing a task to induce mental fatigue (i.e., a Sudoku task). We found that perceived restorative characteristics, preference ratings, experienced pleasure and self-reported restoration were higher in a real natural environment compared to a real urban environment. Perceived restorative characteristics could predict pleasure and restoration for both the real natural and urban environments, as well as preference for the real natural environment. In Study 2, participants (N = 26) visited a virtual natural and a virtual urban environment, again following a mental fatigue induction. Findings showed that virtual simulations of a natural and urban environment elicit similar effects as real counterparts of these environments. Perceived restorative characteristics, preference, pleasure and restoration were higher in a virtual natural environment compared to a virtual urban environment. Additionally, perceived restorative characteristics could predict pleasure and restoration for both the virtual natural and urban environments, and preference for the virtual natural environment. We did not find significant differences in perceived restorative characteristics between the real and virtual butterfly garden. Moreover, similar restorative characteristics predicted preference, pleasure and restoration in the real butterfly garden and the virtual butterfly garden. These findings indicate that virtual reality can be a valid tool for restorative environments research

Multicultural personality and effectiveness in an intercultural training simulation: The role of stress and pro‐active communication

Multicultural personality traits have been shown to predict intercultural outcomes in a range of settings. However, how these traits affect behaviour during intercultural interactions remains an understudied area. A study was conducted among participants in intercultural training sessions, to examine whether scores on the five dimensions of the Multicultural Personality Questionnaire (MPQ) could predict how they performed in the intercultural simulation game “Barnga.” Both a self-rating and other-rating of intercultural effectiveness were included. Furthermore, we examined whether perceived stress and pro-active communication played a mediating role. Results of Latent Growth Curve Modelling (LGCM) show that emotional stability has a positive effect on mean scores (intercept) of both self-rated and other-rated outcomes, mediated through perceived stress. Social Initiative has a positive effect on the rate of improvement (slope) in other-rated outcomes during the simulation, mediated through pro-active communication

TMEM106B a Novel Risk Factor for Frontotemporal Lobar Degeneration

Recently, the first genome-wide association (GWA) study in frontotemporal lobar degeneration (FTLD) identified common genetic variability at the TMEM106B gene on chromosome 7p21.3 as a potential important risk-modifying factor for FTLD with pathologic inclusions of TAR DNA-binding protein (FTLD-TDP), the most common pathological subtype in FTLD. To gather additional evidence for the implication of TMEM106B in FTLD risk, multiple replication studies in geographically distinct populations were set up. In this review, we revise all recent replication and follow-up studies of the FTLD-TDP GWA study and summarize the growing body of evidence that establish TMEM106B as a bona fide risk factor for FTLD. With the TMEM106B gene, a new player has been identified in the pathogenic cascade of FTLD which could hold important implications for the future development of disease-modifying therapies

Economic evaluation of a pharmacogenetic dosing algorithm for coumarin anticoagulants in The Netherlands

AIM: To investigate the cost-effectiveness of a pharmacogenetic dosing algorithm versus a clinical dosing algorithm for coumarin anticoagulants in The Netherlands. MATERIALS & METHODS: A decision-analytic Markov model was used to analyze the cost-effectiveness of pharmacogenetic dosing of phenprocoumon and acenocoumarol versus clinical dosing. RESULTS: Pharmacogenetic dosing increased costs by €33 and quality-adjusted life-years (QALYs) by 0.001. The incremental cost-effectiveness ratios were €28,349 and €24,427 per QALY gained for phenprocoumon and acenocoumarol, respectively. At a willingness-to-pay threshold of €20,000 per QALY, the pharmacogenetic dosing algorithm was not likely to be cost effective compared with the clinical dosing algorithm. CONCLUSION: Pharmacogenetic dosing improves health only slightly when compared with clinical dosing. However, availability of low-cost genotyping would make it a cost-effective option

Variation in Coronary Atherosclerosis Severity Related to a Distinct LDL (Low-Density Lipoprotein) Profile Findings From a Familial Hypercholesterolemia Pig Model

OBJECTIVE: In an adult porcine model of familial hypercholesterolemia (FH), coronary plaque development was characterized. \nTo elucidate the underlying mechanisms of the observed inter-individual variation in disease severity, detailed lipoprotein \nprofiles were determined. \nAPPROACH AND RESULTS: FH pigs (3 years old, homozygous LDLR R84C mutation) received an atherogenic diet for 12 months. \nCoronary atherosclerosis development was monitored using serial invasive imaging and histology. A pronounced difference \nwas observed between mildly diseased pigs which exclusively developed early lesions (maximal plaque burden, 25% [23%\xe2\x80\x93 \n34%]; n=5) and advanced-diseased pigs (n=5) which developed human-like, lumen intruding plaques (maximal plaque burden, \n69% [57%\xe2\x80\x9377%]) with large necrotic cores, intraplaque hemorrhage, and calcifications. Advanced-diseased pigs and mildly \ndiseased pigs displayed no differences in conventional risk factors. Additional plasma lipoprotein profiling by size-exclusion \nchromatography revealed 2 different LDL (low-density lipoprotein) subtypes: regular and larger LDL. Cholesterol, sphingosine1-phosphate, ceramide, and sphingomyelin levels were determined in these LDL-subfractions using standard laboratory \ntechniques and high-pressure liquid chromatography mass-spectrometry analyses, respectively. At 3 months of diet, regular \nLDL of advanced-diseased pigs contained relatively more cholesterol (LDL-C; regular/larger LDL-C ratio 1.7 [1.3\xe2\x80\x931.9] versus \n0.8 [0.6\xe2\x80\x930.9]; P=0.008) than mildly diseased pigs, while larger LDL contained more sphingosine-1-phosphate, ceramides, and \nsphingomyelins. Larger and regular LDL was also found in plasma of 3 patients with homozygous FH with varying LDL-C ratios. \nCONCLUSIONS: In our adult FH pig model, inter-individual differences in atherosclerotic disease severity were directly related to \nthe distribution of cholesterol and sphingolipids over a distinct LDL profile with regular and larger LDL shortly after the diet \nstart. A similar LDL profile was detected in patients with homozygous FH

Functional outcome and quality of life 5 and 12.5 years after aneurysmal subarachnoid haemorrhage

Patients who recover from aneurysmal subarachnoid haemorrhage (SAH) often remain disabled or have persisting symptoms with a reduced quality of life (QoL). We assessed functional outcome and QoL 5 and 12.5 years after SAH. In a consecutive series of 64 patients with mean age at SAH of 51 years, initial outcome assessments had been performed at 4 and 18 months after SAH. At the initial and current outcome assessments, functional outcome was measured with the modified Rankin Scale (mRS) and QoL with the SF-36 and a visual analogue scale (VAS). We studied the change in outcome measurements over time. We used the non-parametric Wilcoxon test to compare differences in mRS grades and calculated differences with corresponding 95% confidence intervals in the domain scores of the SF-36 and the VAS. After 5 years, seven patients had died and five patients had missing data. Compared with the 4-month follow-up, the mRS had improved in 29 of the 52 patients, remained similar in 19 patients. The overall QoL (SF-36 domains and VAS score) was better. At 12.5 years an additional six patients had died. Compared to the 4-month study, 25 of the 46 remaining patients had improved mRS, 12 had remained the same and in nine patients the mRS had worsened. Between the 5 and the 12.5 years follow-up, the improvement in mRS had decreased but patients reported overall a better QoL. Among long-time survivors, QoL may improve more than a decade after SAH

Are physical symptoms among survivors of a disaster presented to the general practitioner? A comparison between self-reports and GP data

<p>Abstract</p> <p>Background</p> <p>Most studies examining medically unexplained symptoms (MUS) have been performed in primary or secondary care and have examined symptoms for which patients sought medical attention. Disasters are often described as precipitating factors for MUS. However, health consequences of disasters are typically measured by means of questionnaires, and it is not known whether these self-reported physical symptoms are presented to the GP. It is also not known if the self-reported symptoms are related to a medical disorder or if they remain medically unexplained. In the present study, three research questions were addressed. Firstly, were self-reported symptoms among survivors presented to the GP? Secondly, were the symptoms presented to the GP associated with a high level of functional impairment and distress? Thirdly, what was the GP's clinical judgment of the presented symptoms, i.e. were the symptoms related to a medical diagnosis or could they be labeled MUS?</p> <p>Methods</p> <p>Survivors of a man-made disaster (N = 887) completed a questionnaire 3 weeks (T1) and 18 months (T2) post-disaster. This longitudinal health survey was combined with an ongoing surveillance program of health problems registered by GPs.</p> <p>Results</p> <p>The majority of self-reported symptoms was not presented to the GP and survivors were most likely to present persistent symptoms to the GP. For example, survivors with stomachache at both T1 and T2 were more likely to report stomachache to their GP (28%) than survivors with stomachache at only T1 (6%) or only T2 (13%). Presentation of individual symptoms to the GP was not consistently associated with functional impairment and distress. 56 – 91% of symptoms were labeled as MUS after clinical examination.</p> <p>Conclusion</p> <p>These results indicate that the majority of self-reported symptoms among survivors of a disaster are not presented to the GP and that the decision to consult with a GP for an individual symptom is not dependent on the level of impairment and distress. Also, self-reported physical symptoms such as headache, back pain and shortness of breath are likely to remain medically unexplained after the clinical judgment of a GP.</p
