The association between social support and the mental health of social workers and police officers who work with unaccompanied asylum-seeking refugee children’s forced repatriation: A Swedish experience

This study aims to contribute to the knowledge of social support and its association with mental health amongst social workers and police officers in forced repatriation work of unaccompanied asylum-seeking refugee children. Nationally distributed surveys to social workers and police officers with and without experience of forced repatriation were used, measured by an abbreviated version of the Interview Schedule for Social Interaction (ISSI), and analyzed by univariate and multivariable regression models. Social workers in forced repatriation showed significantly poorer mental health than other social workers, but simultaneously relatively high access to social support. Irrespective of working with forced repatriation, police officers reported relatively high access to social support, but no difference in mental health. Furthermore, low levels of satisfaction with social interaction and close emotional support increased the odds of psychological disturbances for police officers in forced repatriation. Findings are discussed with special regard to the complexity of forced repatriation, particularly when children are the focus.     

Review of Plasmonic Nanocomposite Metamaterial Absorber

Plasmonic metamaterials are artificial materials typically composed of noble metals in which the features of photonics and electronics are linked by coupling photons to conduction electrons of metal (known as surface _lasmon). These rationally designed structures have spurred interest noticeably since they demonstrate some fascinating properties which are unattainable with naturally occurring materials. Complete absorption of light is one of the recent exotic properties of plasmonic metamaterials which has broadened its application area considerably. This is realized by designing a medium whose impedance matches that of free space while being opaque. If such a medium is filled with some lossy medium, the resulting structure can absorb light totally in a sharp or broad frequency range. Although several types of metamaterials perfect absorber have been demonstrated so far, in the current paper we overview (and focus on) perfect absorbers based on nanocomposites where the total thickness is a few tens of nanometer and the absorption band is broad, tunable and insensitive to the angle of incidence. The nanocomposites consist of metal nanoparticles embedded in a dielectric matrix with a high filling factor close to the percolation threshold. The filling factor can be tailored by the vapor phase co-deposition of the metallic and dielectric components. In addition, novel wet chemical approaches are discussed which are bio-inspired or involve synthesis within levitating Leidenfrost drops, for instance. Moreover, theoretical considerations, optical properties, and potential application of perfect absorbers will be presented.     

Evaluation of Non Diseased Specified Outcome Measures in Hand Injuries to Assess Activity and Participation Based on ICF Content

The objective of the study is to provide information about non disease specified outcome measures which evaluate disability in patients who have impairments in hand and upper extremity and to find the extent to which they are evaluating “disability” based on ICF hand Core Set (activity limitation and participation restriction). MEDLINE, CINAHL, GOOGLE SCHOLAR , OVID and SCIENCE DIRECT databases were systematically searched for studies on non disease specified outcome measures used to evaluate upper extremity function; only studies written in English were considered. We reviewed titles and abstracts of the identified studies to determine whether the studies met predefined eligibility criteria (eg, non disease specified out come measures used in hand injured patients). All the outcome measures which had eligibility included. After full text review ,7 non disease specified outcome measures in hand were identified. Studies were extracted, and the information retrieved from them. All the outcome measures which had incuded, were linked with ICF hand core set disability part (activity and participation). All of them only linked to 16 (42 %) components of ICF hand Core Set, which were most activity and less participation from ICF. None of the non disease specified out come measures in hand injuries cover all domains of disability from the ICF Hand Core Set.     

Assessment of the efficacy of group counselling using cognitive approach on knowledge,attitude, and decision making of pregnant women about modes of delivery

The choice of casarean deliveries by mothers is highly influenced by inadequate knowldge and negative attitudes towards vaginal birth. In this semi-experimental study, we compared knowledge, attitude, and decision making about modes of delivery between nulliparous pregnant women who received eight sessions of group consultation and those who took routine prenatal education. Contrary to the control group, the improvement of knowledge and attitudes were significant in the consultation group (p < 0.001), as well as mothers' decisions for vaginal birth (p = 0.03). Group consultation is an appropriate approach to improving knowledge, attitudes, and tendencies of mothers toward natural birth.     

Trajectory of human movement during sit to stand: a new modeling approach based on movement decomposition and multi-phase cost function

The ability to predict accurately the weights of objects is essential for skilled and dexterous manipulation. A potentially important source of information about object weight is through the observation of other people lifting objects. Here, we tested the hypothesis that when watching an actor lift an object, people naturally learn the object’s weight and use this information to scale forces when they subsequently lift the object themselves. Participants repeatedly lifted an object in turn with an actor. Object weight unpredictably changed between 2 and 7 N every 5th to 9th of the actor’s lifts, and the weight lifted by the participant always matched that previously lifted by the actor. Even though the participants were uninformed about the structure of the experiment, they appropriately adapted their lifting force in the first trial after a weight change. Thus, participants updated their internal representation about the object’s weight, for use in action, when watching a single lift performed by the actor. This ability presumably involves the comparison of predicted and actual sensory information related to actor’s actions, a comparison process that is also fundamental in action.
