Given the addition of new Human Resources (HR) certification offerings by the Society for Human Resource Management and the increase in HR certifications being awarded by the HR Certification Institute, it is necessary to investigate the current rate of demand for HR certification and explore practical implications for those within the field. The current study analyzed over 5,300 HR job announcements and found 20.7% demanded (preferred and/or required) HR certification with more requiring HR certification than before. Additionally, HR certification demand was positively related to salary, experience, education level, and job title with demand reaching 33.7% for managerial HR roles. 相似文献

Theory and research on self‐regulation, emotional adjustment, and interpersonal processes focus increasingly on parasympathetic functioning, using measures of vagally mediated heart rate variability (vmHRV) or respiratory sinus arrhythmia (RSA). This review describes models of vmHRV in these areas, and issues in measurement and analysis. We propose a framework organizing theory and research as examining (a) vmHRV as an individual difference or a situational response, and (b) resting, reactive, or recovery levels. Evidence supports interpretation of individual differences in resting vmHRV as a broad biomarker for adaptive functioning, but its specificity and underlying mechanisms require elaboration. Individual differences in vagal reactivity (i.e., trait‐like differences in vmHRV decreases during challenge or stress) are less commonly studied in adults and results are mixed. Many stressors and challenges evoke temporary decreases in vmHRV, and in some research self‐regulatory effort evokes increases. In a smaller literature, positive interpersonal experiences and some restorative processes increase resting vmHRV, whereas depletion of self‐regulatory capacity through related effort decreases it. Greater attention to conceptual distinctions regarding vmHRV constructs and several methodological issues will strengthen future research. Importantly, researchers should exercise caution in equating vmHRV with specific psychosocial constructs, especially in the absence of converging assessments and precise experimental manipulations. 相似文献
Representing spatial information is one of our most foundational abilities. Yet in the present work we find that even the simplest possible spatial tasks reveal surprising, systematic misrepresentations of space—such as biases wherein objects are perceived and remembered as being nearer to the centers of their surrounding quadrants. We employed both a placement task (in which observers see two differently sized shapes, one of which has a dot in it, and then must place a second dot in the other shape so that their relative locations are equated) and a matching task (in which observers see two dots, each inside a separate shape, and must simply report whether their relative locations are matched). Some of the resulting biases were shape specific. For example, when dots appeared in a triangle during the placement task, the dots placed by observers were biased away from certain parts of the symmetry axes. But other systematic biases were not shape specific, and seemed instead to reflect differences in the grain of resolution for different regions of space. For example, with both a circle and even a shapeless configuration (with only a central landmark) in the matching task, observers were better at discriminating angular differences (when a dot changed positions around the circle, as opposed to inward/outward changes) in cardinal versus oblique sectors. These data reveal a powerful angular spatial bias, and highlight how the resolution of spatial representation differs for different regions and dimensions of space itself.
Recent research shows that people learning a cognitive task acquire a memory for the order of operations applied, independent of the data to which those operations were applied. We designed two experiments to show how this sequence memory is represented. Experiment 1 compared predictions based on 3 possible sequence representation methods: composition, dyad transition, and associative chain. Latency and error results from a simple sequential task supported the associative chain representation. The associative links between operations presumably enhance performance by priming subsequent operations but do not operate in an all-or-none fashion. Experiment 2 explored whether transfer items that matched the first 2 rules and first 3 elements of a training item could bias participants toward executing a composed production learned during training. Latency and undetected error results were consistent with an associative chain representation but not with additional predictions made by the composition representation. These two experiments support the representation of operation sequences in memory as an associative chain. 相似文献
The authors examined job satisfaction, job stress, and thoughts of quitting in relation to positive and negative affect, life satisfaction, self-esteem, and alcohol consumption among police officers. Exploratory and confirmatory factor analyses revealed that 2 dimensions, positive affect and negative affect, provided a clear family-tree organizational framework for representing the otherwise confusing pattern of associations between job and well-being variables. Job satisfaction was primarily associated with positive affect, life satisfaction, and self-esteem; job stress was primarily associated with negative affect and alcohol consumption; thoughts of quitting had moderate loadings on both factors. The 2-dimensional framework may prove useful as a guide in reviewing research in this field and in selecting constructs and measures for inclusion in future research. 相似文献
Past studies have not assessed the prevalence of emotional disturbances in Holocaust survivors seeking medical treatment in a family practice environment. The present study examined the prevalence of lifetime (the presence of symptomatology at any time) and current posttraumatic stress disorder (PTSD) symptoms, general anxiety, and depression in Holocaust survivors seeking medical treatment in a primary care setting. 20 of the 27 Holocaust survivors in our sample received a current diagnosis of PTSD and reported significant symptoms of depression and general anxiety. Although 74% of the survivors were currently diagnosed with PTSD, participants in this study had reported an overall decline in reexperiencing, hyperarousal, and overall PTSD symptoms but exhibited increased avoidance and numbing symptoms throughout the lifespan. These preliminary results suggest that removing avoidance as a defense mechanism during the course of psychotherapy may leave these survivors without an adequate way for coping with their trauma, subsequently increasing their vulnerability to psychopathology. Implications for psychological interventions are provided. 相似文献
The Stevens exponent (beta) can be obtained from proportion estimation judgments using the power model. In this article, the authors extend that model to proportion production, in which the relative magnitudes of 2 stimuli are adjusted to correspond to a numeric proportion (e.g., 1/4 or .25). The model predicts that when beta < 1, small proportions are underproduced, and large proportions are overproduced, but it predicts the reverse when beta > 1, which is the opposite of the predicted patterns for estimation. Eight participants estimated and produced magnitudes and proportions with spatial volume (beta < 1; Experiment 1) and color saturation (beta > 1; Experiment 2). The model's predictions were generally supported. An extension of the model using reference points can account for multicycle patterns shown by some participants. 相似文献
