The coordination of shoulder girdle muscles during repetitive arm movements at either slow or fast pace among women with or without neck-shoulder pain

Purpose: The aim of this study was to evaluate the coordination of the shoulder girdle muscles among subjects with or without neck-shoulder pain performing repetitive arm movement at either a slow or fast pace. Methods: Thirty female adults were allocated to one of two groups—healthy controls or cases with neck-shoulder pain. Surface electromyography (sEMG) signals from the clavicular, acromial, middle and lower trapezius portions and the serratus anterior muscles were recorded during a task performed for 20 min at a slow pace and 20 min at a fast pace. The root mean square (RMS), relative rest time (RRT) and normalised mutual information (NMI, an index of functional connectivity between two muscles in a pair) were computed. Results: No significant differences on RMS, RRT and NMI were found between groups. For both groups, the fast movement pace resulted in increased levels of RMS, lower degrees of RRT and higher NMI compared to the slow pace. No interaction between group and movement pace was found. Conclusions: This study highlights the change in sEMG activity of muscles to meet the demands of performing a task at fast movement pace. The fast pace imposed a higher muscle demand evidenced by increased sEMG amplitude, low degree of muscle rest and increased functional connectivity for subjects in both the case and control groups. No indication of impaired sEMG activity was found in individuals with neck-shoulder pain.     

Autistic Heterogeneity: Linking Uncertainties and Indeterminacies

Autism is a highly uncertain entity and little is said about it with any degree of certainty. Scientists must, and do, work through these uncertainties in the course of their work. Scientists explain uncertainty in autism research through discussion of epistemological uncertainties which suggest that diverse methods and techniques make results hard to reconcile, ontological uncertainties which suggest doubt over taxonomic coherence, but also through reference to autism’s indeterminacy which suggests that the condition is inherently heterogeneous. Indeed, indeterminacy takes two forms—an inter-personal form which suggests that there are fundamental differences between individuals with autism and an intra-personal form which suggests that no one factor is able to explain all features of autism within a given individual. What is apparent in the case of autism is that scientists put uncertainty and indeterminacy into discussion with one another and, rather than a well-policed epistemic-ontic boundary, there is a movement between, and an entwinement of, the two. Understanding scientists’ dialogue concerning uncertainty and indeterminacy is of importance for understanding autism and autistic heterogeneity but also for understanding uncertainty and ‘uncertainty work’ within science more generally.     

Iraqi refugee men’s experiences of psychotherapy: clinical implications and the proposal of a pluralistic model

The psychotherapy experiences of a sample of Iraqi refugee men, in later stages of exile, were explored with the aim of shedding some light on how this client group can experience therapy. Ten adult male Iraqi refugees – who had lived in Sweden for at least five years and had been psychotherapy clients at some point during that time – were recruited for this study. Using individual semi-structured interviews (in Arabic), three main areas were explored with each participant: (1) reasons for seeking psychotherapy; (2) perceptions of the psychotherapy professional; and (3) experiences of the psychotherapy process and outcome. The interviews were then translated into English, transcribed, and then analysed using Interpretative Phenomenological Analysis (IPA). Most participants/clients described exile-related stressors as their main reason for seeking psychotherapy, but some described distress due to a combination of pre-migration trauma and post-migration stress. They also found some aspects of therapy to be positive (mainly verbalising ones thoughts and feelings, and feeling less marginalised) and some negative (mainly experiencing racist or culturally insensitive treatment by therapists, and experiencing a lack of competence and transparency in therapists). The findings were explored in terms of clinical implications and a pluralistic model was proposed to address the identified needs.     

Interrole conflict and self-efficacy to manage work and family demands mediate the relationships of job and family demands with stress in the job and family domains

Background and objectives: This study derives from Work–Home Resources model (ten Brummelhuis, L. L., & Bakker, A. B. (2012). A resource perspective on the work–home interface: The work–home resources model. American Psychologist, 67(7), 545–556. doi:10.1037/a0027974) and Social Cognitive Theory (Bandura, A. (1986). Social foundations of thought and action: A social cognitive theory. Englewood Cliffs, NJ, US: Prentice-Hall, Inc.) to investigate mechanisms responsible for the effect of job and family demands on work- and family-related perceived stress. We hypothesized that interrole conflict and self-efficacy to manage work and family demands operate either independently or sequentially transmitting the effects of demands on perceived stress. Design: A sample of 100 employees of various occupations participated in the study conducted online in two waves: Time 1 (T1) and Time 2 (T2) with a three-month interval. Method: Regression analysis with bootstrapping was applied. Results: Interrole conflict (T1) did not mediate the relationships between demands (T1) and perceived stress (T2), whereas self-efficacy (T1) mediated only those between family demands (T1) and stress (T2). However, data supported the sequential mediation hypotheses: Demands (T1) were associated with increased interrole conflict (T1) which in turn decreased self-efficacy (T1) and ultimately resulted in the elevated perceived stress at work and in the family (T2). Conclusions: Demands originating in one domain can impact stress both in the same and other life areas through the sequence of interrole conflict and context-specific self-efficacy.     

Racial/ethnic bullying: Exploring links between bullying and racism in the US workplace

This study examined relations between the incidence of workplace bullying and the everyday experiences of members of ethnic and racial minorities in the American workplace. Particular attention was paid to expressions of bullying that overtly or specifically refer to race or ethnicity, in the form of more or less subtle acts of discrimination and hostile treatment, introducing the term `racial/ethnic bullying.' Participants belonging to four racial/ethnic groups (Asians, African-Americans, Hispanics/Latinos, and whites) responded to a written survey of general and racial/ethnic bullying experiences, responses, and preferred modes and methods of internal organizational redress and dispute resolution. Very different profiles emerged between bullying perpetrated by supervisors/superiors versus co-workers/peers in the organization.

双职工家庭父母工作投入对初中生学业投入的影响

基于资源保存理论,采用工作投入问卷、关系网络问卷、学业自我效能感问卷、学业投入问卷对326个双职工家庭的父母及其初中生子女进行调查,探讨父母工作投入对初中生学业投入的影响。结果表明：（1）父母工作投入、父母社会支持、子女学业自我效能感、子女学业投入两两之间呈显著正相关;（2）父母社会支持和子女学业自我效能感在父母工作投入影响子女学业投入中起中介作用;（3）父母社会支持和子女学业自我效能感的中介效应不存在显著的性别角色差异。从资源保存理论来看,父母工作投入对子女学业投入的影响,在一定程度上反映了资源在家庭系统内的投资和增益过程。

Linking Work Events,Affective States,and Attitudes: An Empirical Study of Managers' Emotions

The aim of the paper is to contribute to knowledge on the causes and consequences of affective states at work by identifying several job-related events likely to produce affective states and then studying the impact of the latter on work attitudes. Affective Events Theory was the theoretical framework used for the study and two main hypotheses were stated: experiencing certain work events leads to affective reactions, which in turn influence work attitudes. An empirical study based on 203 questionnaires was performed on a sample of French managers. The results support both research hypotheses, although the impact of affective states on work attitudes appeared larger than the impact of work events on affective states. The mediating effect of affective events with respect to the impact of work events was also tested, but only partially supported.
