BackgroundAttention deficit hyperactivity disorder is clinically diagnosed; however, quantitative analysis to statistically analyze the symptom severity of children with ADHD via the measurement of head movement is still in progress. Studies focusing on the cues that may influence the attention of children with ADHD in classroom settings, where children spend a considerable amount of time, are relatively scarce. Virtual reality allows real-life simulation of classroom environments and thus provides an opportunity to test a range of theories in a naturalistic and (...) controlled manner. The objective of this study was to investigate the correlation between participants’ head movements and their reports of inattention and hyperactivity, and to investigate how their head movements are affected by different social cues of different sensory modalities.MethodsThirty-seven children and adolescents with and without ADHD were recruited for this study. All participants were assessed for diagnoses, clinical symptoms, and self-reported symptoms. A virtual reality-continuous performance test was conducted under four conditions: control, no-cue, visual cue, and visual/audio cue. A quantitativecomparison of the participants’ head movements was conducted in three dimensions using a head-mounted display in a VR classroom environment. Task-irrelevant head movements were analyzed separately, considering the dimension of movement needed to perform the VR-CPT.ResultsThe magnitude of head movement, especially task-irrelevant head movement, significantly correlated with the current standard of clinical assessment in the ADHD group. Regarding the four conditions, head movement showed changes according to the complexity of social cues in both the ADHD and healthy control groups.ConclusionChildren and adolescents with ADHD showed decreasing task-irrelevant movements in the presence of social stimuli toward the intended orientation. As a proof-of-concept study, this study preliminarily identifies the potential of VR as a tool to understand and investigate the classroom behavior of children with ADHD in a controlled, systematic manner.

Study with reference to philosophy of Joseph F. Fletcher on christian ethics.

This study viewed students majoring in public relations as prospective public relations practitioners and explored their perceptions about corporate social responsibility (CSR) as their job attraction condition. The results showed that the students perceived CSR to be an important ethical fit condition of a company. One of the significant findings is that CSR can be an effective reputation management strategy for prospective employees, particularly when a company’s business is suffering. In examining the effect of CSR efforts on attitudinal and behavioral (...) outcomes, person–organization (P–O) fit appeared to serve as a mediator between CSR performances and organizational attractiveness.

This study examined the role of religion in xenophobic responses to the threat of Ebola. Religious communities often offer members strong social ties and social support, which may help members cope with psychological and physical threat, including global threats like Ebola. Our analysis of a nationally representative sample in the U.S. found that overall, the more vulnerable to Ebola people felt, the more they exhibited xenophobic responses, but this relationship was moderated by importance of religion. Those who perceived religion as (...) more important in their lives exhibited weaker xenophobic reactions than those who perceived religion as less important. Furthermore, social connectedness measured by collectivism explained the moderating role of religion, suggesting that higher collectivism associated with religion served as a psychological buffer. Religious people showed attenuated threat responses because they had a stronger social system that may offer resources for its members to cope with psychological and physical threats. The current research highlights that different cultural groups react to increased threats in divergent ways. (shrink)

Quantitative assessments of when infectious disease outbreaks end are crucial, as resources targeted towards outbreak responses typically remain in place until outbreaks are declared over. Recent improvements and innovations in mathematical approaches for determining when outbreaks end provide public health authorities with more confidence when making end-of-outbreak declarations. Although quantitative analyses of outbreaks have a long history, more complex mathematical and statistical methodologies for analysing outbreak data were developed early in the 20th century and continue to be refined. Historically, such (...) methodologies focused primarily on factors affecting the early and middle phases of an outbreak, with less attention given to determining how and when outbreaks end. This review discusses mathematical modelling methods from the last 20 years that have been developed for determining the ends of infectious disease outbreaks, and considers factors that affect the accuracy of such determinations. When disease surveillance systems provide timely and representative data to inform models, the timings of end-of-outbreak declarations can be fine-tuned to allow outbreaks to be declared over quickly and with a low risk of being incorrect. Premature declarations that outbreaks are over can undermine earlier achievements in disease control and may result in a resurgence of cases, but unnecessary delays in declaring outbreaks over can cause significant economic and social harm. Appropriate declarations that balance the benefits of relaxing control measures against the risk of a surge in cases allow public health resources to be conserved (and economic and social pressures to be reduced) while limiting the potential for additional transmission.

T‐bet and Eomes are two related transcription factors (TFs) that regulate the differentiation of cytotoxic lymphocytes such as Natural Killer (NK) cells and CD8 T cells. Recent genome‐wide analyses suggest they have complementary roles in instructing the transcriptional program of NK cells, although their DNA binding sites appear to be very similar. In this essay, we discuss the mechanisms that could specify their action, addressing their expression profile, the cofactors they interact with, as well as their roles in the epigenetic (...) regulation of chromatin accessibility. Based on the recent literature on these TFs, we propose different models to describe how they regulate gene expression in NK cells at steady state, or in the context of activation or exhaustion. We also discuss recent findings in the field of CD8 T cell differentiation and residency, where Eomes and T‐bet appear to be major regulators, and the parallels that can be drawn between mechanisms of NK and CD8 T cell differentiation and trafficking.

Excerpt from Poetarum Philosophorum Fragmenta Plagulis correctis indicibusque non sine taedio confectis dum respiro et laetiore animo quid praefandum sit meditor, ecce nuntius longe tris tissimus afi'ertur, georgium kaibelium nobis litterisque acerba morte ereptum esse, qui non solum studiorum societate inde a beatissimo oon tu'oernio - Bonnensi mihi erat coniunctissimus, sed in hoc quoque communi amicorum opere velut auspex et signifer, cuius auctoritatem me aequi et decebat et iuvabat.

The appearance of the time derivative of the acceleration in the equation of motion (EOM) of an electric charge is studied. It is shown that when an electric charge is accelerated, a stress force exists in the curved electric field of the accelerated charge, and in the case of a constant linear acceleration, this force is proportional to the acceleration. This stress force acts as a reaction force which is responsible for the creation of the radiation (instead of the “radiation (...) reaction force” that actually does not exist at low velocities). Thus the initial acceleration should be supplied as an initial condition for the solution of the EOM of an electric charge. (shrink)

ObjectiveWe aim to investigate the feasibility of using diffusion tensor imaging to evaluate changes in extraocular muscles and lacrimal gland in patients with thyroid-associated ophthalmopathy and to evaluate disease severity.Materials and MethodsA total of 74 participants, including 17 healthy controls, 22 patients with mild TAO, and 35 patients with moderate-severe TAO, underwent 3-Tesla DTI to measure fractional anisotropy and mean diffusivity of the EOMs and LG. Ophthalmological examinations, including visual acuity, exophthalmos, intraocular pressure, and fundoscopy, were performed. FA and MD (...) values were compared among patients with different disease severity. Multiple linear regression was adopted to predict the impact of clinical variables on DTI parameters of orbital soft tissue.ResultsTAO patients’ EOMs and LG showed significantly lower FA values and higher MD compared to HCs’. Moderate-severe TAO patients’ EOMs and LG had dramatically lower FA and higher MD compared with HCs. In addition, only the DTI parameters of the medial rectus were considerably different between mild and moderate-severe TAO patients. Multiple linear regression showed that disease severity had a significant impact on the DTI parameters of orbital soft tissue.ConclusionDTI is a useful tool for detecting microstructural changes in TAO patients’ orbital soft tissue. DTI findings, especially medial rectus DTI parameters, can help to indicate the disease severity in TAO patients. (shrink)
