Role Stress: Burnout Antecedent in Nursing Professionals

Abstract

Burnout syndrome has been described by different authors as a reaction to work stress. Hence both the role stress components–role ambiguity and role conflict–appear in the literature as burnout antecedent variables. The correlation between these variables is positive. On the other hand, the work social support (from supervisors and colleagues) is a variable with influence on both role stress and burnout, so the people who perceive higher work social support feel lower role stress and lower burnout than the people who perceive lower social support. In this study we present the results of a correlational study of role ambiguity, role conflict, burnout levels (tested with Maslach Burnout Inventory), and the work social support effects on the relations. The sample are 102 nursing professionals, 24 per cent males and 76 per cent females. The results present a positive correlation between both role ambiguity and role conflict, and the emotional exhaustion scale and depersonalization scale, and a negative correlation between both role conflict and role ambiguity, and reduced personal accomplishment and work social support influence on the relations.     

Personality change following religious conversion: perceptions of converts and their close acquaintances

This study focuses on how converts and their close acquaintances perceive changes in personality characteristics after religious conversion and possible demographic influences of these perceptions. Sixty Slovakian respondents self-defined as having experienced conversions rated themselves twice on measures of Big Five personality traits, self-esteem, and meaningfulness in life. The first rating provided retrospective information concerning pre-conversion conditions and the second rating obtained data reflecting the convert's present self-understanding. In addition, every convert was rated on the same characteristics by someone who knew the person well during both pre- and post-conversion times. The convert and the rater both provided demographic information (age, education, religiosity, relationship to conversions and converts etc.). Analyses showed that the converts perceived several personality changes: neuroticism decreased while self-esteem, agreeableness, conscientiousness, and extraversion increased. They also reported a large increase in meaningfulness. Perceived changes were in part related to education level and age for converts, and to religiosity in both converts and close persons, suggesting a retrospective bias.     

Spatial Working Memory in Aging and Mild Cognitive Impairment: Effects of Task Load and Contextual Cueing

ABSTRACT

Mild Cognitive Impairment (MCI) is characterized by episodic memory deficits, while aspects of working memory may also be implicated, but studies into this latter domain are scarce and results are inconclusive. Using a computerized search paradigm, this study compares 25 young adults, 25 typically aging older adults and 15 amnestic MCI patients as to their working-memory capacities for object-location information and potential differential effects of memory load and additional context cues. An age-related deficit in visuospatial working-memory maintenance was found that became more pronounced with increasing task demands. The MCI group additionally showed reduced maintenance of bound information, i.e., object-location associations, again especially at elevated memory load. No effects of contextual cueing were found. The current findings indicate that working memory should be considered when screening patients for suspected MCI and monitoring its progression.     

Health Is Associated With Antiparasite Behavior and Fear of Disease-Relevant Animals in Humans

Evolutionary arms races between humans and parasites resulted in a set of behavioral adaptations that serve as parasite-avoidance mechanisms. We investigated associations among reported health of the respondent, antiparasite behavior, and sensitivity to disgust and fear of disease-relevant and irrelevant animals. Ninety-seven participants (15–19 years old) rated their fear and disgust at 25 colorful pictures of disease-relevant and disease-irrelevant invertebrates. Consistent with previous work, we found that participants reported greater fear and disgust of disease-relevant invertebrates relative to disease-irrelevant invertebrates. Better perceived health correlated with lower fear of disease-relevant invertebrates. Sensitivity to disgust correlated with reported antiparasite behaviors. Contrary to expectations, we found a positive correlation between antiparasite behavior and reported health, which suggests that antiparasite behavior influences perceived health (but not vice versa), and we found that males perform more antiparasite behaviors than females. These results support the idea that disgust and fear of disease-relevant objects are adaptive emotions that prevent contact with contagious objects, especially in individuals with low perceived health.     

Young Tennis Players’ Competitive Task Involvement and Performance: The Role of Goal Orientations,Contextual Motivational Climate,And Coach-Initiated Motivational Climate

The purpose of this study was to examine the role of situational and dispositional factors in contributing to competitive task involvement and performance in young tennis players. One hundred fifty-one adolescent tennis players and their coaches participated in the study. Participants responded to instruments measuring pre-game dispositional goal orientations and perceptions of the motivational climate and post-game task involvement in the competition by assessing concentration, loss of self-consciousness, and autotelic experience, perceptions of coach-initiated motivational climate in competition, and self-evaluation of game performance. In addition, coaches evaluated the players’ performance. Results showed that task involvement was predicted by players’ perceptions of a coach-initiated learning motivational climate in competition. Loss of self-consciousness was predicted by the players’ perceptions of a coach-initiated performance climate in competition. Finally, coaches’ and players’ assessment of performance were predicted by autotelic experience, concentration, and by perception of coach-initiated learning and performance orientation in competition.     

Alcohol increases hypnotic susceptibility

One approach to hypnosis suggests that for hypnotic experience to occur frontal lobe activity must be attenuated. For example, cold control theory posits that a lack of awareness of intentions is responsible for the experience of involuntariness and/or the subjective reality of hypnotic suggestions. The mid-dorso-lateral prefrontal cortex and the ACC are candidate regions for such awareness. Alcohol impairs frontal lobe executive function. This study examined whether alcohol affects hypnotisability. We administered 0.8 mg/kg of alcohol or a placebo to 32 medium susceptible participants. They were subsequently hypnotised and given hypnotic suggestions. All participants believed they had received some alcohol. Participants in the alcohol condition were more susceptible to hypnotic suggestions than participants in the placebo condition. Impaired frontal lobe activity facilitates hypnotic responding, which supports theories postulating that attenuation of executive function facilitates hypnotic response, and contradicts theories postulating that hypnotic response involves enhanced inhibitory, attentional or other executive function.     

Egg arrangement in avian clutches covaries with the rejection of foreign eggs

In birds, the colour, maculation, shape, and size of their eggs play critical roles in discrimination of foreign eggs in the clutch. So far, however, no study has examined the role of egg arrangement within a clutch on host rejection responses. We predicted that individual females which maintain consistent egg arrangements within their clutch would be better able to detect and reject foreign eggs than females without a consistent egg arrangement (i.e. whose eggs change positions more often across incubation). We tested this “egg arrangement hypothesis” in blackbirds (Turdus merula) and song thrush (T. philomelos). Both species are suitable candidates for research on egg rejection, because they show high inter-individual variation and individual repeatability in egg rejection responses. As predicted, using our custom-defined metrics of egg arrangement, rejecter females’ clutches showed significantly more consistent patterns in egg arrangement than acceptor females’ clutches. Only parameters related to blunt pole showed consistent differences between rejecters and acceptors. This finding makes biological sense because it is already known that song thrush use blunt pole cues to reject foreign eggs. We propose that a disturbance of the original egg arrangement pattern by the laying parasite may alert host females that maintain a consistent egg arrangement to the risk of having been parasitized. Once alerted, these hosts may shift their discrimination thresholds to be more restrictive so as to reject a foreign egg with higher probability. Future studies will benefit from experimentally testing whether these two and other parasitized rejecter host species may rely on the use of consistent egg arrangements as a component of their anti-parasitic defence mechanisms.     

Buddhism as a value source in the course of new identity and lifestyle formation in the Czech Republic

This study is focused on cultural phenomena of contemporary Europe: the creation of a new religious identity without cultural precedent in European cultural history. It will concentrate on non-Asian Buddhist converts, who have adopted religious world views different from those of their ethnic heritage and the mainstream culture they live in and who use Buddhism as the value-source for their children's upbringing. The parents who, to a certain degree, master Buddhist practice and are attached to this particular religious culture, accumulate a specific religious capital which develops when there are higher levels of religious participation, knowledge and experience, including social networks. The aim of my study is to illustrate how accumulated religious capital and value models affect parental choice regarding children's education. How are these values transmitted within the families of different Buddhist streams? What is the role of the local Buddhist community in family life?
