Feedback im Arbeitsleben - eine Selbstwert-Perspektive

Zusammenfassung: Feedback ist unerlässlich und allgegenwärtig. Konstruktives Feedback ist ein wichtiges Führungsinstrument. Gutes Feedback zu geben, ist jedoch alles andere als einfach, und nicht selten fühlen sich Mitarbeitende durch Feedback verletzt und demotiviert. Ein zentraler Aspekt guten Feedbacks bezieht sich auf Aufrechterhaltung, Förderung oder Schädigung des Selbstwerts; der vorliegende Artikel beleuchtet Feedback vor allem unter diesem Aspekt. Diskutiert werden die Bedeutung des Feedbacks für den Selbstwert, Kriterien für optimales Feedback sowie die Schwierigkeiten, optimales Feedback zu geben wie auch Feedback anzunehmen, wobei negatives Feedback im Vordergrund steht. Abschließend wird auf Feedback im Rahmen betrieblicher Leistungsbewertung eingegange

Perceived stress and team performance during a simulated resuscitation

Purpose: Barriers to optimal performance of cardiopulmonary resuscitation may partly relate to human factors, such as stress and specific emotions. The aim of this study was to investigate whether mental stress and different perceived emotions have a negative impact on the performance of rescuers. Methods: This prospective, observational study was conducted at the Simulator Center of the University Hospital Basel, Switzerland. A total of 120 medical students (70% female) participated in teams of three. They reported levels of perceived stress, feeling overwhelmed, motivation and specific emotions before, during, and after a simulated resuscitation. The association of stress/overload (index of stress and feeling overwhelmed), motivation, and specific emotions with resuscitation performance defined as hands-on time during the first 180s after cardiac arrest was investigated. Results: During resuscitation, levels of stress/overload, motivation, and negative emotions were significantly higher as compared to the periods before and after resuscitation. In contrast, positive emotions were highest before and after resuscitation and significantly lower during resuscitation. In general, females reported higher stress/overload and negative emotions, whereas males reported more positive emotions. A multivariate linear regression model showed negative associations of stress/overload (regression coefficient −18.12, 95% CI −30.73, −5.51, p=0.006) and positive associations of motivation (regression coefficient 13.45, 95% CI 0.95, 25.95, p=0.036) with resuscitation performance. Conclusion: A simulated cardiac arrest caused substantial perceived stress/overload and negative emotions, particularly in female students, which adversely impacted resuscitation performance. Further studies are required to expand our findings to more experienced medical professionals and investigate whether stress coping strategies improve resuscitation performanc

Outcome assessment in low back pain: how low can you go?

The present study examined the psychometric characteristics of a "core-set” of six individual questions (on pain, function, symptom-specific well-being, work disability, social disability and satisfaction) for use in low back pain (LBP) outcome assessment. A questionnaire booklet was administered to 277 German-speaking LBP patients with a range of common diagnoses, before and 6months after surgical (N=187) or conservative (N=90) treatment. The core-set items were embedded in the booklet alongside validated ‘reference' questionnaires: Likert scales for back/leg pain; Roland and Morris disability scale; WHO Quality of Life scale; Psychological General Well-Being Index. A further 45 patients with chronic LBP completed the booklet twice in 1-2weeks. The minimal reliability (similar to Cronbach's alpha) for each core item was 0.42-0.78, increasing to 0.84 for a composite index score comprising all items plus an additional question on general well-being (‘quality of life'). Floor or ceiling effects of 20-50% were observed for some items before surgery (function, symptom-specific well-being) and some items after it (disability, function). The intraclass correlation coefficient (ICC) ("test-retest reliability”) was moderate to excellent (ICC, 0.67-0.95) for the individual core items and excellent (ICC, 0.91) for the composite index score. With the exception of "symptom-specific well-being”, the correlations between each core item and its corresponding reference questionnaire ("validity”) were between 0.61 and 0.79. Both the composite index and the individual items differentiated (P<0.001) between the severity of the back problem in surgical and conservative patients (validity). The composite index score had an effect size (sensitivity to change) of 0.95, which was larger than most of the reference questionnaires (0.47-1.01); for individual core items, the effect sizes were 0.52-0.87. The core items provide a simple, practical, reliable, valid and sensitive assessment of outcome in LBP patients. We recommend the widespread and consistent use of the core-set items and their composite score index to promote standardisation of outcome measurements in clinical trials, multicentre studies, routine quality management and surgical registry system

The METCRAX II Field Experiment: A Study of Downslope Windstorm-Type Flows in Arizona\u2019s Meteor Crater

The second Meteor Crater Experiment (METCRAX II) was conducted in October 2013 at Arizona\u2019s Meteor Crater. The experiment was designed to investigate nighttime downslope windstorm 12type flows that form regularly above the inner southwest sidewall of the 1.2-km diameter crater as a southwesterly mesoscale katabatic flow cascades over the crater rim. The objective of METCRAX II is to determine the causes of these strong, intermittent, and turbulent inflows that bring warm-air intrusions into the southwest part of the crater. This article provides an overview of the scientific goals of the experiment; summarizes the measurements, the crater topography, and the synoptic meteorology of the study period; and presents initial analysis results

Humane Orientation as a New Cultural Dimension of the GLOBE Project: A Validation Study of the GLOBE Scale and Out-Group Humane Orientation in 25 Countries

We validate, extend, and empirically and theoretically criticize the cultural dimension of humane orientation of the project GLOBE (Global Leadership and Organizational Behavior Effectiveness Research Program). Theoretically, humane orientation is not just a one-dimensionally positive concept about being caring, altruistic, and kind to others as discussed by Kabasakal and Bodur (2004), but there is also a certain ambivalence to this concept. We suggest differentiating humane orientation toward in-group members from humane orientation toward out-group members. A multicountry construct validation study used student samples from 25 countries that were either high or low in humane orientation (N = 876) and studied their relation to the traditional GLOBE scale and other cultural-level measures (agreeableness, religiosity, authoritarianism, and welfare state score). Findings revealed a strong correlation between humane orientation and agreeableness, welfare state score, and religiosity. Out-group humane orientation proved to be the more relevant subfacet of the original humane orientation construct, suggesting that future research on humane orientation should make use of this measure instead of the vague original scale. The ambivalent character of out-group humane orientation is displayed in its positive correlation to high authoritarianism. Patriotism was used as a control variable for noncritical acceptance of one’s society but did not change the correlations. Our findings are discussed as an example of how rigid expectations and a lack of tolerance for diversity may help explain the ambivalent nature of humane orientatio

The influence of mothers' and fathers' parenting stress and depressive symptoms on own and partner's parent-child communication

This study examines how parenting stress and depressive symptoms experienced by mothers and fathers influence their own (actor effects) and the partner's (partner effects) parent–child communication. Based on the Actor-Partner Interdependence Model, data from 196 families were analyzed, with both parents rating their parenting stress and depressive feelings, and parents as well as children rating the open parent–child communication. Actor effects were found between parenting stress and open parent–child communication, whereas partner effects were prominent between depressive symptoms and open parent–child communication. The results provide no evidence for gender differences in the strength of the pathways to open parent–child communication. Our findings demonstrate the need to include both parents in studies on parent–child communication to enhance our understanding of the mutual influence among family members

An overview of ISCAT 2000

The Investigation of Sulfur Chemistry in the Antarctic Troposphere (ISCAT) took place over the timer period of 15 November to 31 December in the year 2000. The study location was the Amundsen Scott Station in Antarctica. ISCAT 2000 defines the second phase of a program designed to explore tropospheric chemistry in Antarctica. As in 1998, the 2000 ISCAT study revealed a strong oxidizing environment at South Pole (SP). During the 2000 investigation, however, the suite of measurements was greatly expanded. These new measurements established the recycling of reactive nitrogen as a critical component of this unique environment. This paper first presents the historical background leading up to the ISCAT 2000 observations; then it focuses on providing a summary of the year 2000 results and contrasts these with those recorded during 1998. Important developments made during the 2000 study included the recording of SP data for several species being emitted from the snowpack. These included NO, H 2O2 and CH2O. In this context, eddy-diffusion flux measurements provided the first quantitative estimates of the SP NO and NOx snow-to-atmosphere fluxes. This study also revealed that HNO 3 and HO2NO2 were major sink species for HOx and NOx radicals. And, it identified the critical factors responsible for SP NO levels exceeding those at other polar sites by nearly an order of magnitude. Finally, it reports on the levels of gas phase sulfur species and provides evidence indicating that the absence of DMS at SP is most likely due to its greatly shorten chemical lifetime in the near vicinity of the plateau. It is proposed that this is due to the influence of NO on the distribution of OH in the lower free troposphere over a region that extends well beyond the plateau itself. Details related to each of the above findings plus others can be found in the 11 accompanying Special Issue papers. © 2004 Elsevier Ltd. All rights reserved
