Screening for prostate cancer with the prostate-specific antigen blood test is controversial, as evidence to date has not demonstrated such screening does more good than harm. While the potential benefit of PSA screening on reducing prostate cancer mortality has not been documented in randomized trials, many risks of PSA screening have been well documented. These risks include a substantially higher risk of a prostate cancer diagnosis over a screenee’s lifetime, false-positive and false-negative test results, possible complications from biopsies done (...) in response to suspicious test results, and substantial risks of side effects from subsequent prostate cancer treatments. Nevertheless, PSA screening is widespread in the United States, and many physicians in a national survey reported supporting routine PSA screening as well as getting PSA tests themselves, despite the lack of evidence.

The impact of the KK-modes in d-brane models of gravity with large compactification radii and TeV-scale quantum gravity on the hadronic potential at small impact parameters is examined. The effects of the gravitational hadron form factors obtained from the hadron generalized parton distributions (GPDs) on the behavior of the gravitational potential and the possible spin correlation effects are also analysed.

Nitric oxide (NO) is involved in synaptic long-term potentiation (LTP) by multiple signaling pathways. Here, we show that LTP of synaptic transmission can be explained as a feature of signal transduction—bistable behavior in a chain of biochemical reactions with positive feedback, formed by diffusion of NO to the presynaptic site and facilitating the release of glutamate (Glu). The dynamics of Glu, calcium (Ca2+) and NO is described by a system of nonlinear reaction–diffusion equations with modified Michaelis–Menten (MM) kinetics. Numerical (...) investigation reveals that the chain of biochemical reactions analyzed can exhibit a bistable behavior under physiological conditions when production of Glu is described by MM kinetics and decay of NO is modeled by means of two enzymatic pathways with different kinetic properties. Our finding extends understanding of the role of NO in LTP: a short high-intensity stimulus is “memorized” as a long-lasting elevation of NO concentration. The conclusions obtained by analysis of the chain of biochemical reactions describing LTP can be generalized to other chains of interactions or for creating the logical elements for biological computers.

In recent years, the practices of work organizations have raised increasing concerns regarding individual privacy at work. It is clear that people expect and value privacy in their personal lives. However, the extent to which privacy perceptions influence individuals’ work attitudes is less clear. Research has explored the extent to which employee perceptions of privacy derive from characteristics of the programs themselves. However, there is a paucity of research that examines how the characteristics of the individual employee may influence perceptions (...) of these programs. In this study we seek to shed light on this issue, as we examine how the individual ethical orientation of employees influences perceptions of a variety of human resource programs that have the potential to be perceived as invasive. Results indicate that ethical orientation exerts direct effects on perceived invasiveness of programs and exerts both direct and indirect effects on perceived appropriateness of programs. Implications for research and for managers adopting privacy-related programs are discussed. (shrink)

Processing the motivational relevance of a visual scene and reacting accordingly is crucial for survival. Previous work suggests the emotional content of naturalistic scenes affects response speed, such that unpleasant content slows responses whereas pleasant content accelerates responses. It is unclear whether these effects reflect motor-cognitive processes, such as attentional orienting, or vary with the function/outcome of the motor response itself. Four experiments manipulated participants’ ability to terminate the picture and, thereby, the response’s function and motivational value. Attentive orienting was (...) manipulated via picture repetition, which diminishes orienting. A total of N = 81 participants completed versions of a go/no-go task, discriminating between distorted versus intact pictures drawn from six content categories varying in positive, negative, or neutral valence. While all participants responded faster with repetition, only participants without offset control exhibited slower responses to unpleasant and accelerated responses to pleasant content. Emotional engagement, measured by the late positive potential, was not modulated by attentional orienting, suggesting that the interaction between repetition and offset control is not due to altered emotional engagement. Together, results suggest that response time changes as a function of emotional content and sensitivity to attention orienting depends on the motivational function of the motor response. (shrink)

Is it fair for employers to select candidates partly based on how the employers think customers react to the candidates' appearances, that is, based on candidates' reaction qualifications? Both philosophically (in the literature on wrongful discrimination) and empirically, this question has recently been getting attention. Here, we focus on a theory of unfair disadvantages emphasizing (i) whether the possession of the appearance feature in question reflects choices on the part of the candidate and (ii) whether the appearance feature in (...) question reflects values or convictions of importance to the candidate. We scrutinize the theory by evaluating how well these factors map on to folk intuitions about wrongful discrimination using an experimental-philosophical approach and data from the United States. We do so on the presumption that coherence with folk intuitions is one desideratum for a philosophical theory and that attention should be given to potential discrepancies between philosophical theories and folk intuitions. Our central finding is that there is only general support for factor (i), not (ii), in the American population. Our study also adds to the extant empirical literature on reaction qualifications that tend to focus on the employer's side of the matter, not the candidate's as we do. (shrink)

While unethical behaviors that are intended to benefit the self are often severely punished, unethical behaviors that are intended to benefit the organization (unethical pro-organizational behaviors, UPBs) are disciplined within organizations at different levels of severity. Building on the sensemaking theoretical framework, we study how employees make sense of what the organization is like through observing what the organization has done (i.e., different levels of punishment imposed for UPBs) and how employees subsequently react to the results of sensemaking (i.e., affective (...) commitment to the organization)—increased or decreased turnover and UPB engagement intention. By conducting a vignette-based experimental study and a time-lagged field study, we find that affective commitment to the organization of observers, especially those with a high moral disengagement propensity, increases at a low-to-moderate level of punishment severity for UPBs, and decreases at a moderate-to-high level of punishment severity for UPBs. Furthermore, the impacted affective commitment to the organization subsequently leads to increase in observers’ UPB engagement (intention) and decrease in observers’ turnover intention. We also highlight implications for theory and practice. (shrink)

The potential for biased responses that occur when researchers interact with their study participants has long been of interest to both academicians and practitioners. Given the sensitive nature of the field, researcher interaction biases are of particular concern for business ethics researchers regardless of their preference for survey, experimental, or qualitative methodology. Whereas some ethics researchers may inadvertently bias data by misrecording or misinterpreting responses, other biases may occur when study participants' responses are systematically influenced by the mere introduction (...) of researchers into the participants' environment. Although substantial empirical research has been conducted on the general topic of researcher interaction biases, none has focused specifically on business ethics research. In order to remedy this lack of empirical substantiation in the field, we review the related literature on researcher interaction biases, present an empirical example of how such biases can influence research results in an experiment assessing reactions to insurance fraud, and discuss the implications for business ethics research.

The Serial Reaction Time Task (SRTT) was designed to measure motor sequence learning and is widely used in many fields in cognitive science and neuroscience. However, the common performance measures derived from SRTT—reaction time (RT) difference scores—may not provide valid measures of sequence learning. This is because RT-difference scores may be subject to floor effects and otherwise not sufficiently reflective of learning. A ratio RT measure might minimize floor effects. Furthermore, measures derived from predictive accuracy may provide a (...) better assessment of sequence learning. Accordingly, we developed a Predictive Sequence Learning Task (PSLT) in which performance can be assessed via both RT and predictive accuracy. We compared performance of N = 99 adults on SRTT and PSLT in a within-subjects design and also measured fluid abilities. The RT-difference scores on both tasks were generally not related to fluid abilities, replicating previous findings. In contrast, a ratio RT measure on SRTT and PSLT and accuracy measures on PSLT were related to fluid abilities. The accuracy measures also indicated an age-related decline in performance on PSLT. The current patterns of results were thus inconsistent across different measures on the same tasks, and we demonstrate that this discrepancy is potentially due to floor effects on the RT difference scores. This may limit the potential of SRTT to measure sequence learning and we argue that PSLT accuracy measures could provide a more accurate reflection of learning ability. (shrink)

Possible effects of interaction (cross-talk) between signaling pathways is studied in a system of Reaction–Diffusion (RD) equations. Furthermore, the relevance of spontaneous neurite symmetry breaking and Turing instability has been examined through numerical simulations. The interaction between Retinoic Acid (RA) and Notch signaling pathways is considered as a perturbation to RD system of axon-forming potential for N2a neuroblastoma cells. The present work suggests that large increases to the level of RA–Notch interaction can possibly have substantial impacts on neurite (...) outgrowth and on the process of axon formation. This can be observed by the numerical study of the homogeneous system showing that in the absence of RA–Notch interaction the unperturbed homogeneous system may exhibit different saddle-node bifurcations that are robust under small perturbations by low levels of RA–Notch interactions, while large increases in the level of RA–Notch interaction result in a number of transitions of saddle-node bifurcations into Hopf bifurcations. It is speculated that near a Hopf bifurcation, the regulations between the positive and negative feedbacks change in such a way that spontaneous symmetry breaking takes place only when transport of activated Notch protein takes place at a faster rate.

Bakhtin and Voloshinov argued that dialogue is the intersubjective basis of consciousness, and of the creativity which makes historical changes in consciousness possible. The multiple dialogical relationships give every subject, who has developed through internalising them, the potential to distance him or herself from them. Consciousness is therefore an 'unfinalised' process, always open to a possible future which would not merely reiterate the past. But this book explores its corollary: The relative openness is a field of conflict where rival (...) discourses struggle for hegemony, by subordinating or eliminating their rivals. That is how the unconscious is created out of socio-historical conflicts. Hegemony is always incomplete, because there is always the possibility of a return of its repressed rivals in new combinations. (shrink)

Developmental Coordination Disorder and Attention-Deficit/Hyperactivity Disorder are unique neurodevelopmental disorders with overlaps in executive functions and motor control. The conditions co-occur in up to 50% of cases, raising questions of the pathological mechanisms of DCD versus ADHD. Few studies have examined these overlaps in adults with DCD and/or ADHD. Therefore, to provide insights about executive functions and motor control between adults with DCD, ADHD, both conditions, or typically developed controls, this study used a stop-signal task and parallel EEG measurement. We (...) assessed executive performance via go accuracy and go reaction time, as well as motor response inhibition via stop-signal reaction time. This was complemented with analysis of event-related potentials. Based on existing investigations of adults with DCD or ADHD, we expected groups would not differ in behavioral performance on stop and go trials, but differences in ERPs, particularly in components N200 and P300 would be evident. The sample included N = 50 adults with DCD, ADHD, DCD + ADHD, and control participants. We replicated that there were no between-group differences for behavioral-level executive performance and motor response inhibition. However, on a physiological level, ERP components N200 and P300 differed between groups, particularly during successful response inhibition. These ERPs reflect potential endophenotypic differences not evident in overt behavior of participants with ADHD and/or DCD. This suggests a disorder specific employment of inhibition or general executive functions in groups of adults with DCD, DCD + ADHD, ADHD, or control participants. (shrink)

Employees frequently engage in job crafting to better match their jobs with their personal abilities and skills. Compared with its benefits, the potential detrimental consequences of job crafting have received less attention from researchers. Drawing on relative deprivation theory, we examined employees’ potential negative reactions to coworkers’ job crafting. We proposed that coworkers’ job crafting is positively related to employees’ feelings of relative deprivation, thus reducing prosocial behaviors and giving rise to social undermining. We further argued that employees’ (...) zero-sum mindset moderates the relationship between coworkers’ job crafting and employees’ feelings of relative deprivation, such that the relationship is more positive when the zero-sum mindset is high rather than low. Our hypotheses were generally supported by time-lagged data collected from a sample of 313 employees and their leaders from 85 teams. Our findings advance the understanding of the unintended consequences of job crafting in organizations. (shrink)

The ‘universal cell reaction’ (UCR), a coordinated biphasic response to external (noxious and other) stimuli observed in all living cells, was described by Nasonov and his colleagues in the mid‐20th century. This work has received no attention from cell biologists in the West, but the UCR merits serious consideration. Although it is non‐specific, it is likely to be underpinned by precise mechanisms and, if these mechanisms were characterized and their relationship to the UCR elucidated, then our understanding of the (...) integration of cellular function could be improved. As a step towards identifying such mechanisms, I review some recent advances in understanding cell mechanics and the stress response and I suggest potentially testable hypotheses. There is a particular need for time‐course studies of cellular responses to different stimulus doses or intensities. I also suggest a correspondence with hormesis; re‐investigation of the UCR using modern biophysical and molecular‐biological techniques might throw light on this much‐discussed phenomenon.

Cigarette smoking and other addictive behaviors are among the main preventable risk factors for several severe and potentially fatal diseases. It has been argued that addictive behavior is controlled by an automatic-implicit cognitive system and by a reflective-explicit cognitive system, that operate in parallel to jointly drive human behavior. The present study addresses the formation of implicit attitudes towards smoking in both smokers and non-smokers, using a Go/NoGo association task, and behavioral and electroencephalographic measures. The GNAT assesses, via quantifying participants’ (...) reaction times, the strength of association between a target category and either pole of an evaluative dimension. EEG analysis is performed to determine the temporal course of the event-related potential components underlying Go/NoGo decisions and implicit attitude formation. Both smokers and non-smokers showed prolonged reaction times to smoking-related pictures when the pictures were coupled with positive evaluative words. This indicates negative implicit attitudes towards smoking in both groups alike at the time point of the behavioral response. However, only the non-smokers, not the smokers, were found to show a delay of the N200 component in the incongruent condition. This is interpreted as reflecting ambivalent or even positive implicit attitudes towards smoking in the smoker group at the time point of the N200. Our study thus provides evidence for the hypothesis that implicit attitudes are subject to changes within several hundred milliseconds after stimulus presentation, and can be altered in the course of their formation.

The search for the best wellness practice has promoted the development of devices integrating different technologies and guided meditation. However, the final effects on the electrical activity of the brain remain relatively sparse. Here, we have analyzed of the alpha and theta electroencephalographic oscillations during the realization of the arrest reaction when a chromotherapy session performed in a dedicated room [Rebalance device], with an ergonomic bed integrating pulsed-wave light stimulation, guided breathing, and body scan exercises. We demonstrated that the (...) PWL induced an evoked-related potential characterized by the N2-P3 components maximally recorded on the fronto-central areas and accompanied by an event-related synchronization of the delta–theta–alpha oscillations. The power of the alpha and theta oscillations was analyzed during repeated ARs testing realized along with the whole RB session. We showed that the power of the alpha and theta oscillations was significantly increased during the session in comparison to their values recorded before. Of the 14 participants, 11 and 6 showed a significant power increase of the alpha and theta oscillations, respectively. These increased powers were not observed in two different control groups who stayed passively outside or inside the RB room but without any type of stimulation. These preliminary results suggest that PWL chromotherapy and guided relaxation induce measurable electrical brain changes that could be beneficial under neuropsychiatric perspectives. (shrink)

Museums are safe spaces for the objects they hold and for the persons that visit them, providing environments that can function in therapeutic ways. Within the wide range of objects, there is enough diversity to help guests discover what similarities they have with others as well as what makes them unique as individuals. Within exhibits, individuals can explore themselves through the reactions they have to particular pieces, through the observation of what holds their attention within the environment, and through the (...) awareness and development of their contemplative mind. Museums can introduce transpersonal information, add information to previous transpersonal experiences, and even promote expanded states of awareness. With direction, guests can use museums to learn about themselves, thus optimizing the therapeutic potentials of these institutions. (shrink)

The present study applies a new method for investigating dynamic unconscious processes. The method consists of selection of words from patient interview and test protocols that in the clinicians' judgments capture the patients' conscious symptom experience and the hypothetical unconscious conflict related to the symptom, subliminal and supraliminal presentation of these words, signal analysis of event-related potentials obtained to the word presentations. Eight phobics and three patients suffering from pathological grief reactions served as subjects. A time-frequency ERP analysis revealed that (...) subjects' ERPs classified the unconscious conflict words better subliminally than supraliminally, while the reverse was true for the conscious symptom words = 2.82, p = .011). The relationship between frequency and latency revealed a similar mirror image pattern for the unconscious conflict and conscious symptom words . This method demonstrated that objective, brain-based evidence for unconscious conflict can be obtained. (shrink)

Appearance discrimination may restrict the opportunities of minority groups, including national, religious, and racial minorities. Employers sometimes impose appearance codes on their workforce that disproportionately affect these groups, potentially limiting their access to jobs. It is tempting to think that the solution here is simple. In practice, it might be said, the appearance features that are excluded by these codes often mask the real basis of the discrimination. Seen in their true light, these codes generally involve direct discrimination on the (...) basis of race, religion or nationality. Even when they do not, if they have a worse effect on a disadvantaged group, then they are cases of indirect discrimination. But things are not that simple, for an appearance feature can be a genuine reaction qualification, i.e., it can be a genuine qualification in virtue of the responses of those who come into contact with an employee, such as customers or clients. This chapter addresses the issue of when it is morally permissible for an employer to adopt an appearance code that disadvantages a minority group by pandering to the preferences of their customers or clients in cases where these preferences express their aesthetic tastes or are rooted in reasonable conceptions of the good to which they adhere. Consideration is given to whether the importance of integration might provide a reason to regard appearance codes as morally impermissible when it is harder or more costly for a minority group, such as a national, religious, or racial minority, to conform to them.

The present study is the first to measure event-related potentials associated with the processing of the emotional Stroop task (EST) with the use of an orthogonal factorial manipulation for emotional valence, arousal, and subjective significance (the importance of the current experience for goals and plans for the future). The current study aimed to investigate concurrently the role of the three dimensions describing the emotion-laden words for interference control measured in the classical version of the EST paradigm. The results showed that (...) reaction times were affected by the emotional valence of presented words and the interactive effect of valence and arousal. The expected emotional arousal effect was only found in behavioral results for neutrally valenced words. Electrophysiological results showed valence and subjective significance correlated with the amplitude differences in the P2 component. Moreover, the amplitude of the N450 component varied with the level of subjective significance. This study also demonstrated that exploratory event-related potential analysis provides additional information beyond the classical component-based analysis. The obtained results show that cognitive control effects in the EST may be altered by manipulation in the subjective significance dimension. (shrink)

Research on employees’ responses to corporate social responsibility has recently accelerated and begun appearing in top-tier academic journals. However, existing findings are still largely fragmented, and this stream of research lacks theoretical consolidation.

Drawing on social identity (...) theory and social exchange theory, we delineate the different but interdependent psychological mechanisms that explain how CSR can strengthen the employee–organization relationship and subsequently foster employee-related, micro-level outcomes. Contributions of our framework to extant literature and potential extensions for future research are then discussed. (shrink)

Appraisal theory assumes that the individual variability of emotional reactions to the same situation is due to individual differences in appraisal. However, the question of how interindividual differences in appraisal come about has been rarely formally addressed. We focus on one of the central dimensions of appraisal—problem-focused coping potential—and attempt to explain individual differences in appraisals along this dimension using self-efficacy theory. We integrate outcome expectancies, self-efficacy expectations, and problem-focused coping potential into a single framework and outline their (...) personality antecedents. Using generalized self-efficacy beliefs as an example, we then discuss the mechanisms underlying the effects of personality dispositions on appraisal and the conditions that moderate their influence. We conclude with the implications for theory, research, and practice. (shrink)

From his consistently religious perspective he foresaw with precision much of (...) the inhuman and tyrannical potential of the revolutionary project. (shrink)

Decades of tobacco control initiatives have turned public opinion against cigarette smoking. Smokers, once considered glamorous, are now stigmatized in domains including the workplace. Extant literature lacks scrutiny of smoker stigmatization and devaluation within the job selection process, and mechanisms that lead to such outcomes. Using an experimental design, we empirically examine initial reactions to job applicants’ smoking behaviors within two samples. We show that initial impressions are significantly worse when job applicants smoke versus do not in a store-based context. (...) Moreover, this effect occurs indirectly through perceived likelihood of engaging in counterproductive work behaviors, and is conditional upon respondents’ own attitudes towards smoking. These relationships—similar for customer service and inventory management jobs—are indicative of potential biases within the hiring process. Implications of these findings, and the moral dilemmas they raise around the treatment of smokers, are discussed from the ethical perspective of human resource management. (shrink)

Faces are characterized by the simultaneous presence of several evaluation-relevant features, for example, emotional expression and (prejudiced) ethnicity. The social message account (SMA) hypothesizes the immediate integration of emotion and ethnicity. According to SMA, happy in-group faces should be interpreted as benevolent, whereas happy out-group faces should be interpreted as potentially malevolent. By contrast, fearful in-group faces should be interpreted as signaling an unsafe environment, whereas fearful out-group faces should be interpreted as signaling inferiority. In contrast, the processing conflict account (...) (PCA) assumes that each face conveys two rather independent evaluative features, emotion and ethnicity. Thus, stimuli might be either affectively congruent or incongruent, and thereby exert influences on behavior. The article reviews the evidence with regard to the two accounts before reporting an experiment that aims at disentangling them. In an approach/avoidance task (AAT), either happy/fearful faces of German and Turks were presented or happy/fearful faces of young and old persons. There are prejudices against Turk/Middle-eastern persons (in Germany) as well as against old persons. For SMA, the two prejudices are of different type; thus prediction for the AAT diverge for the two group conditions. In contrast, for PCA both group features (i.e., Turk ethnicity and old age) are negative features (in comparison to their counterparts) which are affectively congruent or incongruent to the emotional expression. Hence, the results pattern in the AAT should be comparable for the two group conditions. In accordance with SMA but in contrast to PCA, we found different patterns for the two group conditions.

The deBroglie–Bohm quantum potential is the potential energy function of the wave field. The quantum potential facilitates the transference of energy from wave field to particle and back again which accounts for energy conservation in isolated quantum systems. Factors affecting energy exchanges and the form of the quantum potential are discussed together with the related issues of the absence of a source term for the wave field and the lack of a classical back reaction.

Background: It is often necessary to differentiate cutaneous signs of adverse medication reactions from other similar appearances. Because patients frequently fail to recognize the connection between drug consumption and ensuing cutaneous manifestations, early detection of these responses is imperative. Purpose: Investigating the prevalence of Cutaneous Adverse Drug Reactions (CADRs) at a teaching hospital for tertiary care is the goal of this study. Methods: A self-reporting technique was used to select cases in a prospective, observational trial that lasted six months in (...) Saudi German hospital in Jeddah. The following categories applied to Cutaneous Adverse Drug Reactions: definite, potential, and probable. Results: The most common cutaneous manifestation of ADRs (42.85%) was maculopapular rash, which was linked to antimicrobials (48.30%) and nonsteroidal anti-inflammatory drugs (21.90%) during the study period, which resulted in 91 cases of Cutaneous Adverse Drug Reactions. Conclusion: Since cutaneous adverse drug reactions are common, raising awareness of them is crucial to diagnosing and preventing them. (shrink)

The Galilei invariance of classical dynamics does not automatically imply the third Newtonian axiom and the center of mass theorem. For the deduction of these theorems from Galilei invariance we must have, generally, a “kinematical potential” (Helmholtz) and a “potential function” (Clausius), respectively. In celestial mechanics it is possible to have conservation of the motion of the center of gravity but not of the mass center. In this case, the active and the passive masses are different quantities.

Companies increasingly recognize the importance of communicating corporate social responsibility including their engagement toward employees, the community, the environment and other stakeholder groups to attract applicants. The positive findings on the effect of CSR on applicants’ reactions are commonly based on the assumption that companies send a clear signal about their commitment to CSR. However, communication is always contextualized and has become more ambiguous through the increased availability of information online. External stakeholders including actual and potential applicants are confronted (...) with inconsistencies between the way companies communicate CSR activities and their overall CSR performance. Drawing on signaling theory, this article raises the question of how the interaction between strong CSR communication and low CSR performance influences organizational attractiveness. We propose that low CSR performance dampens the effect of CSR communication on organizational attractiveness. Hence, the inconsistency between CSR communication and CSR performance decreases organizational attractiveness. To test our hypotheses, we scraped 67,189 posts published on corporate Facebook career pages by 58 Fortune 500 companies from the time they began their respective career page until June 2018. Surprisingly, our results show that a low CSR performance strengthens the effect of CSR communication on organizational attractiveness. Thus, inconsistencies between CSR communication and CSR performance seem to lead to positive evaluations among applicants. (shrink)

This article reports on exploratory research into social workers? perceptions and actions regarding ?forewarning? clients of their child abuse reporting obligations as a limitation of confidentiality at relationship onset. Ethical principles and previous research on forewarning are discussed prior to stating the research methods and presenting findings. Data obtained from South Australian social workers engaged in human service work with adult family members articulate a strong desire to practise in accordance with professional codes of ethics. However, the findings suggest that (...) proactive forewarning is extremely infrequent, with minimized forewarning accomplished only in response to client-initiated inquiry and where prior suspicions of child abuse may exist. Generally, discomfort with forewarning was found to result in its avoidance due to concerns about client retention, working in tense relationships and personal uncertainties about client's reactions towards participants. Through the avoidance of forewarning, participants are potentially supporting their own personal feelings and viewpoints more actively than the rights of others. This may correlate with having a private model of professionalism in opposition to a public model, in which relationship parameters are presented honestly and openly to clients when establishing the practice context?a problematic issue for ethical social work.

This study investigated the effect of obstructive sleep apnea on the neural mechanism of visual perception. A preliminary case-control study was conducted. Seventeen patients with moderate to severe OSA in the sleep center of Civil Aviation General Hospital and 20 healthy controls matched for age, sex, and education were recruited. The participants accepted the perceptual contour integration task, compared the differences in behavioral indicators between the two groups, and compared the differences in electroencephalography data between the two groups through event-related (...) potential technology. The groups did not differ significantly in age and gender, but they differed significantly in body mass index. The groups were not statistically different in terms of sleep structure and total sleep time. AHI, sleep efficiency, and minimal SaO2 value in the OSA group were significantly different from those of the control group. The results showed that the average reaction time of the OSA group was significantly longer than that of the healthy control group in the contour integration task. There was no significant difference in the accuracy rate. The results of EEG showed that the amplitudes of N100 of the OSA group were significantly higher than those of the control group at O1, Oz, and O2 electrodes. There was no significant difference in latency between the two groups. At the FCz electrode, the amplitudes of N200 of the OSA group were significantly higher than those of the control group. Therefore, we concluded that in the early stage of the perceptual integration task, although the neural response activity of patients with moderate and severe OSA was not accelerated, they need to call on more psychological resources, activate more neurons in the contour global recognition processing stage, and the compensatory effect of frontal lobe appeared in the stage of visual perception.

Inflammation is said to be a healthy component of the body's immune system's reaction. Inflammation is characterised by four key symptoms: pain, redness, heat or warmth and swelling. As secondary metabolites, plants may produce a wide range of phytochemical compounds, which possess anti-inflammatory characteristics. Herbal remedies are important therapies for a wide range of ailments all over the world. There are around 7,500 species of medicinal plants, including representatives from over 17,000 flowering plant species. Even though synthetic chemistry has (...) developed its expectations, the use of natural ingredients in the manufacture of drugs used in contemporary medicine is unparalleled. By interfering with the biology of inflammation, anti-inflammatory medications may assist to minimising tissue damage and increase patient comfort. Because of the bulky figure of species reachable for study, the effective development of novel naturally taking place anti-inflammatory drugs is mostly dependent on a multidisciplinary approach to discovering new chemicals. Despite the statistic that many review papers have been produced in this field, the conventional of them simply examined the issue from an area perspective. Several non-steroidal anti-inflammatory drugs have been shown to reduce inflammation and pain by decreasing the isoform of the cyclooxygenase enzyme's digestion of arachidonic acid, hence lowering prostaglandin production. Non-steroidal anti-inflammatory drugs have a host of harmful effects. There are, however, medicinal herbs with anti-inflammatory pharmacological properties that have few or no negative effects.

Past research on recruitment has shown that employer image predicts job seekers’ perceptions of organizational attractiveness. We contribute to this body of work by examining job seekers’ reactions to a market-dominant employer that has suffered from a case of corporate social irresponsibility (CSI). We show that job seekers’ reaction is buffered in the case of dominant employers’ wrongdoing. This effect is stronger for job seekers who are very interested in working in the dominant employers’ industry. Market dominance, however, reduces (...) the negative impact of CSI only under certain circumstances. We find that market dominance provides a buffer against the negative effect of CSI only when (1) CSI is directly relevant to the domain of performance of the organization and (2) job seekers feel very certain about their attitudes toward the organization. In two experiments with participants actively looking for employment at the time of study, we tested a model of moderated mediation examining how market dominance and CSI influence perceived employer ethicality and perceived employer competence. These two variables, in turn, explain how job seekers form perceptions of organizational attractiveness. This is the first study to explore how job seekers react to potential employers that are dominant in a market but have suffered from a CSI incident. The study identifies the boundary conditions that explain why sometimes market-dominant employers can emerge relatively unscathed in the eyes of job seekers following CSI. The research opens important managerial implications concerning the recruitment efforts of organizations that have suffered from CSI. (shrink)

Online platforms like Instagram cover potentially distressing imagery with a sensitive-content screen (blurred imagery plus a content warning). Previous research suggests people typically choose to “uncover” and view screened content. In three studies, we investigated whether the presence of screens mitigates the negative emotional impact of viewing content. In Study 1, participants viewed positive and neutral images, and screens (with an option to view the negative images beneath) for a 5-minute period. In Study 2, half the participants saw a grey (...) mask in place of the typical sensitive-content screen. In addition, each image appeared for a fixed period (5 s) and participants had no option to uncover it. Study 3 was like Study 2 except half the participants saw negative images preceded by a sensitive-content screen and half saw negative images without screens. Overall, participants reported a significant increase in state anxiety and negative affect from pre-to post task when they were exposed to sensitive-content screens, whether or not they were also exposed to the negative imagery beneath. Our data suggest sensitive-content screens cause negative responses – state anxiety and negative affect – that do not translate to an emotional benefit when people view negative content. (shrink)
