Evaluation of linear and quadratic modal analysis for a partitioned FSI solver

In this paper, linear and quadratic modal approximations of elastodynamic solid deformation in FSI problems are considered. Firstly, the theory of quadratic exten- sion of modal analysis presented in [1] is laid out. The quadratic and linear approximations are then benchmarked against full FEM analysis in various test cases. These are chosen to be representative of flutter considerations in the aerospace field. The quadratic ap- proximation is shown to produce a markedly better prediciton of solid deformation for small to medium deflections

Barriers and facilitators for treatment-seeking for mental health conditions and substance misuse:Multi-perspective focus group study within the military

Background Globally, millions are exposed to stressors at work that increase their vulnerability to develop mental health conditions and substance misuse (such as soldiers, policemen, doctors). However, these types of professionals especially are expected to be strong and healthy, and this contrast may worsen their treatment gap. Although the treatment gap in the military has been studied before, perspectives of different stakeholders involved have largely been ignored, even though they play an important role. Aims To study the barriers and facilitators for treatment-seeking in the military, from three different perspectives. Method In total, 46 people participated, divided into eight homogeneous focus groups, including three perspectives: soldiers with mental health conditions and substance misuse (n = 20), soldiers without mental health conditions and substance misuse (n = 10) and mental health professionals (n = 16). Sessions were audio-taped and transcribed verbatim. Content analysis was done by applying a general inductive approach using ATLAS.ti-8.4.4 software. Results Five barriers for treatment-seeking were identified: fear of negative career consequences, fear of social rejection, confidentiality concerns, the ‘strong worker’ workplace culture and practical barriers. Three facilitators were identified: social support, accessibility and knowledge, and healthcare within the military. The views of the different stakeholder groups were highly congruent. Conclusions Barriers for treatment-seeking were mostly stigma related (fear of career consequences, fear of social rejection and the ‘strong worker’ workplace culture) and this was widely recognised by all groups. Social support from family, peers, supervisors and professionals were identified as important facilitators. A decrease in the treatment gap for mental health conditions and substance misuse is needed and these findings provide direction for future research and destigmatising interventions

Mental health issues and illness and substance use disorder (non-)disclosure to a supervisor: a cross-sectional study on beliefs, attitudes and needs of military personnel

OBJECTIVES: Research suggests that military personnel frequently delay disclosing mental health issues and illness (MHI), including substance use disorder, to supervisors. This delay causes missed opportunities for support and workplace accommodations which may help to avoid adverse occupational outcomes. The current study aims to examine disclosure-related beliefs, attitudes and needs, to create a better understanding of personnel's disclosure decision making. DESIGN: A cross-sectional questionnaire study among military personnel with and without MHI. Beliefs, attitudes and needs regarding the (non-)disclosure decision to a supervisor were examined, including factors associated with (non-)disclosure intentions and decisions. Descriptive and regression (logistic and ordinal) analyses were performed. SETTING: The study took place within the Dutch military. PARTICIPANTS: Military personnel with MHI (n=324) and without MHI (n=554) were participated in this study. OUTCOME MEASURE: (Non-)disclosure intentions and decisions. RESULTS: Common beliefs and attitudes pro non-disclosure were the preference to solve one's own problems (68.3%), the preference for privacy (58.9%) and a variety of stigma-related concerns. Common beliefs and attitudes pro disclosure were that personnel wanted to be their true authentic selves (93.3%) and the desire to act responsibly towards work colleagues (84.5%). The most reported need for future disclosure (96.8%) was having a supervisor who shows an understanding for MHI. The following factors were associated both with non-disclosure intentions and decisions: higher preference for privacy (OR (95% CI))=(1.99 (1.50 to 2.65) intention, 2.05 (1.12 to 3.76) decision) and self-management (OR (95% CI))=(1.64 (1.20 to 2.23) intention, 1.79 (1.00 to 3.20) decision), higher stigma-related concerns (OR (95% CI))=(1.76 (1.12 to 2.77) intention, 2.21 (1.02 to 4.79) decision) and lower quality of supervisor-employee relationship (OR (95% CI))=(0.25 (0.15 to 0.42) intention, 0.47 (0.25 to 0.87) decision). CONCLUSION: To facilitate (early-)disclosure to a supervisor, creating opportunities for workplace support, interventions should focus on decreasing stigma and discrimination and align with personnels' preference for self-management. Furthermore, training is needed for supervisors on how to recognise, and effectively communicate with, personnel with MHI. Focus should also be on improving supervisor-employee relationships

Belemmerende en bevorderende factoren voor hulp zoeken bij psychische klachten of verslaving:Focusgroepstudie vanuit meerdere perspectieven binnen de Nederlandse krijgsmacht

Achtergrond Wereldwijd worden miljoenen mensen op het werk blootgesteld aan stressvolle factoren die de kans op het ontwikkelen van psychische klachten en/of verslaving (PK/V) verhogen (bijvoorbeeld militairen, politie, artsen). Maar het zijn ook juist deze beroepen waar men geacht wordt sterk en gezond te zijn. Hierdoor is het soms moeilijker om hulp te zoeken voor PK/V. Zo laat Engels onderzoek zien dat 60% van de militairen met PK/V hier geen professionele hulp voor zoekt. Eerder onderzoek naar hulp zoeken voor PK/V richtte zich met name op het perspectief van militairen met PK/V, waarbij andere belangrijke perspectieven niet meegenomen werden. Daarnaast is dit probleem niet eerder onderzocht binnen de Nederlandse krijgsmacht. Doel Het doel van de huidige studie was de belemmerende en bevorderende factoren voor het zoeken van hulp voor PK/V in kaart te brengen binnen de Nederlandse krijgsmacht vanuit verschillende perspectieven. Methode In totaal hebben 46 mensen deelgenomen aan de studie verdeeld over acht focusgroepen, met drie verschillende perspectieven: vier groepen militairen met PK/V (totaal 20 deelnemers), twee groepen militairen zonder PK/V (totaal 10 deelnemers) en twee groepen zorgprofessionals (totaal 16 deelnemers). De focusgroepen zijn opgenomen en letterlijk uitgeschreven. Vervolgens is met behulp van kwalitatieve data-analysesoftware contentanalyse uitgevoerd vanuit een inductieve benadering. Resultaten Er zijn vijf belemmerende factoren voor het zoeken van hulp gevonden: (1) angst voor negatieve carrièregevolgen, (2) angst voor sociale afwijzing, (3) zorgen rond de vertrouwelijkheid, (4) de militaire werkcultuur en (5) praktische barrières. Ook zijn drie bevorderende factoren gevonden: (1) sociale steun, (2) toegankelijkheid zorgverlening en kennis over waar hulp te verkrijgen en (3) militaire zorgverlening. Ondanks dat het onderzoek zich expliciet richtte op verschillende perspectieven kwamen de visies van de deelnemers sterk overeen. Conclusie De meeste belemmerende factoren voor het zoeken van hulp waren gerelateerd aan stigma (angst voor carrièregevolgen, sociale afwijzing en militaire werkcultuur) en dit werd benoemd door alle drie de verschillende perspectieven. Sociale steun vanuit het thuisfront, collega’s, leidinggevende en zorgprofessionals werd gezien als bevorderend voor het zoeken van hulp. De resultaten van de huidige studie geven richting voor zowel toekomstig (interventie)onderzoek als beleid, om ervoor te zorgen dat meer militairen hulp zoeken voor PK/V

Pupil size predicts partner choices in online dating

People's choices for specific romantic partners can have far reaching consequences, but very little is known about the process of partner selection. In the current study, we tested whether a measure of physiological arousal, pupillometry (i.e., changes in pupil size), can predict partner choices in an online dating setting. A total of 239 heterosexual participants took part in an online dating task in which they accepted or rejected hypothetical potential partners, while pupil size response was registered using an eye tracker. In line with our main hypothesis, the results indicated a positive association between pupil size and partner acceptance. This association was not found to depend on relationship status, relationship quality, gender, or sociosexual orientation. These findings show that the body (i.e., the pupils) provides an automatic cue of whether a potential partner will be selected as a mate, or rejected

Sustained low prevalence of meticillin-resistant Staphylococcus aureus upon admission to hospital in The Netherlands.

Contains fulltext : 124320.pdf (Publisher’s version ) (Closed access)The prevalence of meticillin-resistant Staphylococcus aureus (MRSA) carriage at hospital admission in The Netherlands was 0.03% in 1999-2000. The aim of the present study was to assess whether the prevalence of MRSA carriage in The Netherlands has changed over the last few years. In five Dutch hospitals, 6496 unique patients were screened for nasal S. aureus carriage at hospital admission by microbiological culture between 1 October 2005 and 7 June 2007. In total, 2036 of 6496 (31.3%) patients carried S. aureus in their nose, and seven of 6496 (0.11%) patients were nasal carriers of MRSA. Compared with 1999-2000, the prevalence of MRSA carriage in the Dutch population at hospital admission has increased more than three fold; however, this increase was not significant (P=0.06, Fisher's exact test). This prevalence is still among the lowest in the world, probably as a result of the stringent Dutch infection control policy, and the restrictive use of antibiotics in The Netherlands.1 november 201
