Psychological Availability between Self-Initiated Expatriates and Host Country Nationals during Their Adjustment: The Moderating Role of Supportive Supervisor Relations

This research examined the role of psychological availability as a means of psychological engagement between self-initiated expatriates (SIEs) and their host-country nationals (HCNs) colleagues during their work and interaction adjustment. To reveal this process, this study presented the concept of psychological availability, which refers to an individual’s belief that they are physically, cognitively, and emotionally ready or confident to engage the self with their colleagues, as a mediator between proactive personality and adjustment. Also, it investigated the relationship between proactive personality and psychological availability and how it was moderated by supportive supervisor relations. We hypothesized, this relationship would be weakened/strengthened when SIEs and HCNs received low/high level of support from their supervisor. This study was conducted as a quantitative study, data was used from 342 SIEs and 342 HCNs working in mainland China. Our finding supported the hypothesis that psychological availability mediated the relationship between proactive personality and their adjustment to an international work environment; in addition, the relationship between proactive personality and psychological availability would be stronger when the level of superiors relations support is high between SIEs and HCNs. This study demonstrated the value of proactive personality as an antecedent effect and supportive supervisor relations as a moderating effect, and investigated how these factors can lead to a sense of psychological availability and boost psychological engagement between SIEs and HCNs in order to improve the adjustment between them.
Effects of Video Feedback on Early Coercive Parent–Child Interactions: The Intervening Role of Caregivers’ Relational Schemas

We examined the effect of adding a video feedback intervention component to the assessment feedback session of the Family Check-Up (FCU) intervention (Dishion & Stormshak, 2007). We hypothesized that the addition of video feedback procedures during the FCU feedback at child age 2 would have a positive effect on caregivers’ negative relational schemas of their child, which in turn would mediate reductions in observed coercive caregiver–child interactions assessed at age 5. We observed the caregiver–child interaction videotapes of 79 high-risk families with toddlers exhibiting clinically significant problem behaviors. A quasi-random sample of families was provided with direct feedback on their interactions during the feedback session of the FCU protocol. Path analysis indicated that reviewing and engaging in feedback about videotaped age 2 assessment predicted reduced caregivers’ negative relational schemas of the child at age 3, which acted as an intervening variable on the reduction of observed parent–child coercive interactions recorded at age 5. Video feedback predicted improved family functioning over and above level of engagement in the FCU in subsequent years, indicating the important incremental contribution of using video feedback procedures in early family-based preventive interventions for problem behaviors. Supportive video feedback on coercive family dynamics is an important strategy for promoting caregiver motivation to reduce negative attributions toward the child, which fuel coercive interactions. Our study also contributes to the clinical and research literature concerning coercion theory and effective intervention strategies by identifying a potential mechanism of change.
SELF-EFFICACY, COMMUNITY VIOLENCE, AND ADOLESCENT DATING VIOLENCE

Researchers have discovered a number of risk factors associated with adolescent dating violence; these include child maltreatment and high levels of conflict in teen dating relationships. This study examined relationships among adolescent dating violence, family violence, community violence, dating history, academic history, and various forms of self-efficacy among 306 high school and university students (age 16 to 19 years). Results showed that psychological, physical, and sexual dating violence were common occurrences among these students, that both males and females admitted perpetrating dating violence, and that dating violence was related to involvement in community violence. Young women in high school who were victims of any form of dating violence demonstrated lower levels of dating self-efficacy (i.e., less confidence in their ability to secure and maintain dating relationships and to protect themselves from dating violence) and those who were victims of sexual dating violence had lower levels of physical selfefficacy. Young men in high school who had perpetrated psychological dating violence had lower academic self-efficacy. Implications for intervention and prevention programs are discussed. Background Adolescence is a significant period of development associated with a variety of new experiences and challenges. Within this period of the life span, the formation of intimate dating relationships is important to the continued healthy development of the individual (McCabe, 1984). Not all dating relationships, however, lead to a positive developmental trajectory. A
An optimum Geometric decoder for MIMO systems

In this paper, we propose a simple implementation of an optimum Geometric decoder (GD) for use in MIMO systems. The decoder uses the channel matrix to construct a hyper paraboloid and then restricts the symbol vectors to be searched to a hyper ellipsoid projected from the hyper paraboloid. Computer simulation results on 4×4 different MIMO systems transmitting 16QAM and 64QAM show that the proposed GD can achieve the same bit-error-rate (BER) performances as those of the Maximum Likelihood (ML) decoder, yet having much less complexity.
Skin layer of diffusive media.

The transport of radiation in the bulk of multiply scattering media is well understood within the diffusion approximation. Such a description does not hold in the skin layers, where the transport mechanism crosses over from free propagation to diffusive propagation, or vice versa. In this work, we examine the effects of the skin layers of optically thick slabs on various quantities, including the angularly resolved diffuse reflection and transmission and the shape of the enhanced backscattering cone. This study is based on the ladder approximation to the multiple-scattering expansion. It does not rely on the diffusion approximation and incorporates a systematic treatment of the internal reflections which take place when the random-scattering medium and the outside have two different optical indices, in an arbitrary ratio m. Many exact results are recovered in the absence of internal reflections (m=1). A systematic approach describes accurately the large-index-mismatch regime (m\ensuremath{\rightarrow}0 or \ensuremath{\infty}), where the improved diffusion approximation is shown to become exact asymptotically. The analytic predictions of the large-index-mismatch approach are compared in a detailed way with numerical results and with the outcomes of previous works.
Assimilation de mesures de flux turbulents d'eau et de carbone dans un modèle de la biosphère continentale

L’assimilation de donnees relatives aux ecosystemes continentaux est une approche de plus en plus utilisee pour tenter de concilier les observations experimentales avec les theories ecophysiologiques appliquees dans les modeles mecanistes de la vegetation. Dans cette these, on souhaite exploiter l’information contenue dans les mesures par correlation turbulente des flux nets de dioxyde de carbone (NEE) et de chaleur latente (LE) effectuees sur les sites du reseau mondial FLUXNET, afin d’optimiser des parametres cles du modele ORCHIDEE et d’affiner le bilan d’incertitude. Une approche statistique bayesienne est adoptee, pour prendre en compte une connaissance a priori des incertitudes relatives aux parametres, aux equations du modele et aux mesures. L’axe majeur de travail est le developpement d’une methode d’assimilation simultanee des donnees de plusieurs sites de mesure de flux, permettant d’optimiser un unique jeu de parametres se voulant generique pour chaque grand type d’ecosysteme considere. Il ressort que cette approche multi-site permet de reduire significativement l’ecart entre le modele et donnees de flux aux echelles saisonniere et annuelle, avec des performances proches d’optimisations uni-site effectuees independamment a l’echelle d’un site de mesure. On discute par ailleurs le fait que les valeurs des parametres multi-site ne constituent pas toujours une simple moyenne de leurs composantes uni-site. L’utilisation de donnees complementaires a par ailleurs permit d’evaluer la capacite de l’optimisation a ameliorer la simulation des flux bruts de carbone (photosynthese et respiration) a l’echelle des sites, ainsi que de la phenologie du couvert vegetal et du cycle saisonnier du CO2 atmospherique a l’echelle du globe. Un aspect de nos developpements methodologiques propose par ailleurs d’estimer la structure statistique de l’erreur derivant des processus mal representes et/ou manquant dans les equations d’un modele de la biosphere continentale tel qu’ORCHIDEE. En appliquant cette technique aux flux nets de carbone, les resultats suggerent que cette erreur modele merite d’etre explicitement consideree dans le bilan d’incertitude attache a la modelisation du cycle du carbone.
On processing scored k-dominant skyline queries

A skyline of a d-dimensional dataset contains the points that are not dominated by any other point on all dimensions. Due to its usefulness, a skyline query has recently received a considerable attention in several applications. However, as the number of dimensions increases, the probability of one point dominating another point becomes very low. In consequence, the number of points in the skyline becomes tremendous. To remedy this disadvantage, the k-dominant skyline has been introduced, which relaxes the domination relationship. Although the number of k-dominant skyline points is smaller than the number of skyline points, some important points in the dataset may be excluded from the result of a k-dominant skyline query due to the cyclic dominance relationship. With this problem in mind, we introduce a novel types of skyline queries, called the scored k-dominant skyline query. A scored k-dominant skyline is computed from skyline points by utilizing the notions of (i) k-dominance relationship and (ii) k-dominant score. We also present the search algorithm for the scored k-dominant skyline. Finally, we demonstrate the effectiveness of the scored k-dominant skyline through a set of simulations by using both real dataset and synthetic dataset.
Impedance shaping of grid-connected three-phase PV systems

The growing demand for clean energy sources has driven the insertion of photovoltaics (PV) in low-voltage networks. However, the non-dispatchable nature of these units can produce instability issues like voltage fluctuations or frequency deviation. It can be worse if these units are connected to a weak network. One way to overcome this problem is to impose suitable impedance values on PV inverter. However, it is hard to shape the PV output impedance by simply adjusting its control loop gains. For that reason, this paper proposes a method for shaping the PV output impedance by using a virtual impedance scheme, which can be designed independently of the PV control system. With the proposed method, the stability margin of grid-connected system can be increased by imposing desirable PV output impedance. Experimental results validate the proposed impedance shaping strategy.
Energy efficient routing to reduce flooding in weighted rough set model using MANET

A mobile ad-hoc networks consists of wireless hosts that may move often, movement of host results changes in path. The well known Fisheye state routing (FSR) protocol determines a route when no route exists or route breaks. To establish new path from source to destination, it broadcast control packets (route request packets), which increases the network bandwidth, as there is a great reduce in total energy consumed (TEC) and average energy consumed (AEC) for reduced flooding than other two techniques - probabilistic broadcasting algorithm, propagating neighbourhood method. As mobile ad-hoc networks have limited bandwidth, it is important to reduce the flooding. This paper provides a protocol which uses the weighted rough set model which dominates probabilistic broadcasting algorithm and propagating neighbourhood method to control the route request packets in the existing FSR protocol in GRID. Weighted rough set theory is a mathematical tool to deal with vagueness, uncertainty and it also considers the importance of the objects (nodes).
What Can an Arm Holster Worn Smart Phone Do for Activity Recognition?

While mobile phones are increasingly being used in activity recognition, tasks that require arm motion monitoring have so far not been studied on phone platforms. We leverage the fact that upper arm holsters are an increasingly popular way of wearing mobile devices during physical exercise to investigate the suitability of such platforms for arm dominated activity recognition. We focus on (1) user independent recognition from (2) a NULL class dominated, continuous data stream and (3) requiring no special care in device attachment (apart from being placed in a commercial holster). These are 3 key requirements for a realization in a real life mobile "App". We evaluate our methods on a gym exercises data set from 7 users that contains 11'000 individual repetitions of 10 different upper body exercises organized in 700 "sets" (=consecutive repetitions of the same exercise). On set level we achieve a user independent recognition of 93.6%. In over 90% of cases we can also count individual instances with an accuracy of +/-20%.
A Low-Profile Wideband Substrate-Integrated Waveguide Cavity-Backed E-Shaped Patch Antenna for the Q-LINKPAN Applications

A low-profile substrate-integrated waveguide cavity-backed E-shaped patch antenna is proposed for the Q-LINKPAN application in this paper. In order to expand the operating bandwidth, a co-planar waveguide (CPW) is used to feed the proposed antenna with a metallized via for generating one more resonant mode. In addition, a substrate-integrated cavity is employed to suppress the surface wave and improve the radiation efficiency. A differential feeding network is used in the design to improve the symmetry of the E-plane radiation pattern and the H-plane cross polarization. A $2 \times 2$ prototype is designed, fabricated, and measured for a demonstration. The measured results show that the prototype has a 10 dB impedance bandwidth of 34.4%, a gain of around 12.5 dBi with a narrow E-plane radiation beam within 37.5–46 GHz for long distance applications, and a gain of around 8 dBi with a broad E-plane radiation beam within 47–53 GHz for short distance applications. The proposed technique can be used to develop compact planar antenna for meeting both the short- and long-rang communication requirements of the emerging Q-LINKPAN wireless system.
PTEN Directly Activates the Actin Depolymerization Factor Cofilin-1 During PGE2-Mediated Inhibition of Phagocytosis of Fungi

By promoting actin depolymerization, the protein phosphatase activity of PTEN impairs macrophage phagocytosis of a fungal pathogen. Preventing Phagocytosis The fungus Candida albicans is normally a commensal microbe found on mucosal surfaces, including those in the lung. However, C. albicans can cause systemic infections that are a leading cause of morbidity and mortality in immunocompromised individuals. A key innate immune response to C. albicans is its ingestion (phagocytosis) by macrophages, a process that requires polymerization of the actin cytoskeleton. Another component of the macrophage response to fungus is the production of prostaglandin E2 (PGE2), a lipid mediator whose synthesis is initiated by cyclooxygenase (COX) enzymes. Serezani et al. found that infection of alveolar macrophages with C. albicans triggered the production of PGE2, which prevented polymerization of the actin cytoskeleton and inhibited phagocytosis of C. albicans by alveolar macrophages. The authors defined the signaling pathway involved. These results suggest that COX inhibitors, such as aspirin, which are in widespread clinical use, may stimulate innate immune responses. In addition, immunosuppression is associated with increased production of PGE2, which may help to explain how antifungal responses are attenuated in immunocompromised individuals. Macrophage ingestion of the yeast Candida albicans requires its recognition by multiple receptors and the activation of diverse signaling programs. Synthesis of the lipid mediator prostaglandin E2 (PGE2) and generation of cyclic adenosine monophosphate (cAMP) also accompany this process. Here, we characterized the mechanisms underlying PGE2-mediated inhibition of phagocytosis and filamentous actin (F-actin) polymerization in response to ingestion of C. albicans by alveolar macrophages. PGE2 suppressed phagocytosis and F-actin formation through the PGE2 receptors EP2 and EP4, cAMP, and activation of types I and II protein kinase A. Dephosphorylation and activation of the actin depolymerizing factor cofilin-1 were necessary for these inhibitory effects of PGE2. PGE2-dependent activation of cofilin-1 was mediated by the protein phosphatase activity of PTEN (phosphatase and tensin homolog deleted on chromosome 10), with which it directly associated. Because enhanced production of PGE2 accompanies many immunosuppressed states, the PTEN-dependent pathway described here may contribute to impaired antifungal defenses.
A Study of Linear Density Dependence of Media Noise Power in Perpendicular Magnetic Recording

Media noise power saturates at high linear density in perpendicular magnetic recording. It has been reported that one of the root causes is transition noise saturation due to unsaturated magnetization governed by transition width. However, noise saturation phenomena cannot be fully explained by this mechanism alone. For example, low noise media which saturate at lower linear density show better read-write performance. In this study, we show that noise saturation can be explained by a combination of a readback effect and a noise spectrum that changes with density.

TESTING A PREDICTIVE THEORETICAL MODEL FOR THE MASS LOSS RATES OF COOL STARS

The basic mechanisms responsible for producing winds from cool, late-type stars are still largely unknown. We take inspiration from recent progress in understanding solar wind acceleration to develop a physically motivated model of the time-steady mass loss rates of cool main-sequence stars and evolved giants. This model follows the energy flux of magnetohydrodynamic turbulence from a subsurface convection zone to its eventual dissipation and escape through open magnetic flux tubes. We show how Alfvén waves and turbulence can produce winds in either a hot corona or a cool extended chromosphere, and we specify the conditions that determine whether or not coronal heating occurs. These models do not utilize arbitrary normalization factors, but instead predict the mass loss rate directly from a star's fundamental properties. We take account of stellar magnetic activity by extending standard age-activity-rotation indicators to include the evolution of the filling factor of strong photospheric magnetic fields. We compared the predicted mass loss rates with observed values for 47 stars and found significantly better agreement than was obtained from the popular scaling laws of Reimers, Schröder, and Cuntz. The algorithm used to compute cool-star mass loss rates is provided as a self-contained and efficient computer code. We anticipate that the results from this kind of model can be incorporated straightforwardly into stellar evolution calculations and population synthesis techniques.
A MEMS‐based heating holder for the direct imaging of simultaneous in‐situ heating and biasing experiments in scanning/transmission electron microscopes

The introduction of scanning/transmission electron microscopes (S/TEM) with sub‐Angstrom resolution as well as fast and sensitive detection solutions support direct observation of dynamic phenomena in‐situ at the atomic scale. Thereby, in‐situ specimen holders play a crucial role: accurate control of the applied in‐situ stimulus on the nanostructure combined with the overall system stability to assure atomic resolution are paramount for a successful in‐situ S/TEM experiment. For those reasons, MEMS‐based TEM sample holders are becoming one of the preferred choices, also enabling a high precision in measurements of the in‐situ parameter for more reproducible data.
Pathway to Hope: an indigenous approach to healing child sexual abuse

Background The Alaska Native (AN) population has endured multiple historical traumatic events. This population has poorer health outcomes on nearly all factors compared with Alaska non-Natives with more than 75% reportedly being physically assaulted in their lifetime, and child sexual abuse nearly 6 times the national average. Objective This article describes the Pathway to Hope (PTH) program, which is an indigenous approach to ending silence and denial related to child sexual abuse and encourages multigenerational healing. Design PTH was developed by ANs who believe that each community is unique, thus strategies for ending denial and support for healing must be woven from the historical context, cultural strengths of individual communities. Strengths-based solutions built on truth, honesty, compassion and shared responsibility for healing and protecting today's children have been profound and successful. The PTH curriculum addresses child sexual abuse from a historical perspective; that the higher rates of sexual abuse among certain Tribes, regions and communities is linked in part to years of victimisation, but may also be perpetuated by internalised oppression and lateral violence among Tribal members. Results Data suggest that community-based dialogue and wisdom of Native elders and spiritual leaders paired with readiness of community service providers are necessary for sustained change. At all levels, this Indigenous model for learning, sharing, helping and healing brings hope for an end to denial and silence about child sexual abuse for Native people. Conclusion The PTH program utilises the wisdom and values that have sustained Native people for generations. Ending silence and denial about child sexual abuse and building upon strengths have assisted many Indigenous communities begin the journey toward wellness. Through the PTH, communities have taken steps to accept the challenges associated with establishing safety for children, supporting child victims in healing and to holding offenders accountable.
