    Background. Low and middle income countries (LMICs) are facing an increase of the impact of mental health problems while confronted with limited resources and limited access to mental health care, known as the ‘mental health gap’. One strategy to reduce the mental health gap would be to utilize the internet to provide more widely-distributed and low cost mental health care. We undertook this systematic review to investigate the effectiveness and efficacy of online interventions in LMICs. Methods. We systematically searched the data-bases PubMed, PsycINFO, JMIR, and additional sources. MeSH terms, Thesaurus, and free text keywords were used. We included all randomized controlled trials (RCTs) of online interventions in LMICs. Results. We found only three articles reported results of RCTs on online interventions for mental health conditions in LMICs, but none of these interventions was compared with an active control condition. Also, the mental health conditions were diverse across the three studies. Conclusions. There is a dearth of studies examining the effect of online interventions in LMICs, so we cannot draw a firm conclusion on its effectiveness. However, given the effectiveness of online interventions in high income countries and sharp increase of internet access in LMICs, online interventions may offer a potential to help reduce the ‘mental health gap’. More studies are urgently needed in LMICs

    Cooperation of general practitioners and occupational physicians: Identity, trust and responsibility

    Our study shows that different social psychological mechanisms have a profound effect on the quality of the cooperation of GPs and OPs. Especially we found significant differences between the two professions in professional identity, relative position, dependency, trust and responsibility. There is a significant correlation between the number of contacts and the evaluation of the contacts and between the number of contacts and trust in the communication. Apparently trust in the quality of the work is not the problem. Our results suggest ways of improving education and training. On base of our findings we suggest the following interventions: 1. OPs should improve their own professional identity. They should work on internal contacts and create a more cohesive group. The professional group should present itself more clearly. The professional association of OPs could play a prominent role in this. This association is already active in producing standards and composing a declaration of intent. These are useful steps in this view. 2. GPs need to be better informed about what an OP does. It will then be clearer in which respects the well-being of the patient will gain quality when they use the expertise of OPs. Accepting and using the mutual dependency of GP and OP is beneficial for the patient. 3. More possibilities for contacts between GPs and OPs. They could for instance talk about the division of tasks and responsibilities; also about communication. Talking as equal colleagues is the most important factor, having a communal problem: the patient

    A superfluid hydrodynamic model for the enhanced moments of inertia of molecules in liquid 4He

    We present a superfluid hydrodynamic model for the increase in moment of inertia, ΔI\Delta I, of molecules rotating in liquid 4^4He. The static inhomogeneous He density around each molecule (calculated using the Orsay-Paris liquid 4^4He density functional) is assumed to adiabatically follow the rotation of the molecule. We find that the ΔI\Delta I values created by the viscousless and irrotational flow are in good agreement with the observed increases for several molecules [ OCS, (HCN)2_2, HCCCN, and HCCCH3_3 ]. For HCN and HCCH, our model substantially overestimates ΔI\Delta I. This is likely to result from a (partial) breakdown of the adiabatic following approximation.Comment: 4 pages, 1 eps figure, corrected version of published paper.

    Worst-Case Morphs using Wasserstein ALI and Improved MIPGAN

    Full text link
    A morph is a combination of two separate facial images and contains identity information of two different people. When used in an identity document, both people can be authenticated by a biometric Face Recognition (FR) system. Morphs can be generated using either a landmark-based approach or approaches based on deep learning such as Generative Adversarial Networks (GAN). In a recent paper, we introduced a \emph{worst-case} upper bound on how challenging morphing attacks can be for an FR system. The closer morphs are to this upper bound, the bigger the challenge they pose to FR. We introduced an approach with which it was possible to generate morphs that approximate this upper bound for a known FR system (white box), but not for unknown (black box) FR systems. In this paper, we introduce a morph generation method that can approximate worst-case morphs even when the FR system is not known. A key contribution is that we include the goal of generating difficult morphs \emph{during} training. Our method is based on Adversarially Learned Inference (ALI) and uses concepts from Wasserstein GANs trained with Gradient Penalty, which were introduced to stabilise the training of GANs. We include these concepts to achieve similar improvement in training stability and call the resulting method Wasserstein ALI (WALI). We finetune WALI using loss functions designed specifically to improve the ability to manipulate identity information in facial images and show how it can generate morphs that are more challenging for FR systems than landmark- or GAN-based morphs. We also show how our findings can be used to improve MIPGAN, an existing StyleGAN-based morph generator

    Attentional Bias for Cues Signaling Punishment and Reward in Adolescents:Cross-Sectional and Prognostic Associations with Symptoms of Anxiety and Behavioral Disorders

    Heightened reward sensitivity has been proposed as a risk factor for developing behavioral disorders whereas heightened punishment sensitivity has been related to the development of anxiety disorders in youth. Combining a cross-sectional (n = 696, mean age = 16.14) and prospective (n = 598, mean age = 20.20) approach, this study tested the hypotheses that an attentional bias for punishing cues is involved in the development of anxiety disorders and an attentional bias for rewarding cues in the development of behavioral disorders. A spatial orientation task was used to examine the relation between an attentional bias for punishing cues and an attentional bias for rewarding cues with anxiety and behavioral problems in a subsample of a large prospective population cohort study. Our study indicates that attentional biases to general cues of punishment and reward do not seem to be important risk factors for the development of anxiety or behavioral problems respectively. It might be that attentional biases play a role in the maintenance of psychological problems. This remains open for future research
