This study assessed secondborn adolescents' perceptions of changes in the allocation of family resources following their firstborn siblings' departure from home after high school, and whether perceived changes were related to changes over 1 year in secondborns' academic functioning. Participants were secondborn siblings (mean age = 16.58, SD = 0.91) from 115 families in which the older sibling had left the family home in the previous year. Allocation of resources was measured via coded qualitative interviews. Most (77%) secondborns reported increases in at least one type of family resource (i.e., parental companionship, attention, material goods), and many reported an increase in multiple types of resources in the year following their older sibling's departure. Consistent with resource dilution theory, perceptions of increases in fathers' companionship, fathers' attention, and mothers' companionship were related to improvements over time in secondborns' academic functioning.  相似文献

According to Conservation of Resources (COR) theory, this study investigated the explanatory role of perceived employability, over and above core self-evaluations (CSE) and job resources, in relation to different aspects of health (physical and mental) and turnover intentions. Based on data obtained from a sample of 274 Romanian blue-collar employees (59.5% men), hierarchical multiple regressions revealed that perceived employability adds a significant variance compared to variance due to CSE and job resources with respect to aspects of health and turnover. The results highlight the role of perceived employability in health – on an individual level, and in decisions to leave the organization – on an organizational level. The findings are of value because they inform organizations how to design human resources strategies in order to retain a healthy workforce.  相似文献

Considering how much we know about the impact of the Sense of Coherence (SOC) on different health‐related outcomes, we know surprisingly little about how a strong SOC actually develops. In this study we examine the mechanisms behind the formation of a strong SOC and study the role of migration, integration and general resistance resources (GRRs) in this process. We held 46 life‐story interviews with women of Turkish, Moroccan and Surinamese descent. We divided the respondents in a relatively strong and weak SOC group in order to discern patterns of life experiences associated with SOC development. We find that, as Antonovsky predicted, experiencing consistency and load balance are associated with a strong SOC. In opposition to Antonovsky's claims, decision making power is not a necessary condition to develop meaningfulness. Moreover, the women's life narratives show that migration and integration are related to the mechanisms shaping SOC, yet, the impact is subjective and depends on the availability and use of GRRs. Our findings provide improvements to Antonovsky's salutogenic theory and provide suggestions for interventions aimed at strengthening SOC.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

This paper describes the phenomenological ethics implicit in Heidegger’s later work. It is argued that these phenomenological ethics take the form of a perfectionist ethics in which one consciously resists the temptation to nihilistically enframe other entities as Bestand. Despite Heidegger’s reputation as an inferior animal philosopher, it is then argued that we can employ this ethics to improve our relationship with non-human animals. Specifically, our use of them in the agricultural setting is examined to determine whether or not our current practices are ethical according to Heidegger’s normative model. Ultimately it is concluded that, more often than not, animals are harmed both ontically and ontologically by our modern farming practices. We are called on instead to try to dwell meditatively with other entities, to be-with them in such a way that respects them as inexhaustibly meaningful instantiations of being as such. This requires changes to the way in which we satisfy our needs as consumers.  相似文献

An experience-grounded semantics is introduced for an intelligent reasoning system, which is adaptive, and works with insufficient knowledge and resources. According to this semantics, truth and meaning are defined with respect to the experience of the system – the truth value of a statement indicates the amount of available evidence, and the meaning of a term indicates its experienced relations with other terms. The major difference between experience-grounded semantics and model-theoretic semantics is that the former does not assume the sufficiency of knowledge and resources. This approach provides new ideas to the solution of some important problems in cognitive science.  相似文献

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.  相似文献
