This study explores the cognitive effects of emotional visuals and company–cause fit in CSR communication. We conducted a 2 (valence of visuals: positive vs. negative)?×?2 (company–cause fit: high vs. low) within-subjects experiment to examine the effects of valence and company–cause fit on participants’ memory of CSR information, measured by recognition sensitivity and cued recall of company information in CSR messages addressing three different CSR issues. Results showed that negative emotional visuals were more effective than positive emotional visuals. Company–cause fit also played a significant role, but its effect depended on the level of cognitive effects aimed for. We discuss the theoretical and practical implications.  相似文献

Public relations professionals strive to develop mutually beneficial relationships among key publics that will result in favorable organizational reputations, but crises typically threaten those reputations. Much of public relations crisis research focuses on how to respond after a crisis, but drawing on Expectation Violation Theory (EVT), this research focuses on the expectations of stakeholders before a crisis and how they process information during a crisis. Drawing from reputation management research in marketing, it conceptualizes corporate reputations as encompassing associations related to corporate ability (CA) and corporate social responsibility (CSR). Reputation management research generally has investigated reputations as strong on either CA or CSR, but this research examines the effects of a “hybrid” reputation, which is strong in terms of both CA and CSR associations. The results of an experiment reveal that stakeholders’ responses during a crisis vary based on their expectations, how they perceive a hybrid reputation, and the crisis type. The study has theoretical implications regarding stakeholders’ information processing during a crisis, and it provides public relations professionals insights regarding how to cultivate and protect an organizational reputation.  相似文献

Background

Recent studies show that human placenta, processed and encapsulated for postpartum consumption, contains a host of trace minerals and hormones that could conceivably affect maternal physiology. Our objective was to investigate whether salivary hormone concentrations of women ingesting their own encapsulated placenta during the early postpartum differed from those of women consuming a placebo.

Methods

Randomly assigned participants (N = 27) were given a supplement containing either their dehydrated and homogenized placenta (n = 12), or placebo (n = 15). Saliva samples were collected during late pregnancy and early postpartum. Samples of participants’ processed placenta, and the encapsulated placebo, were also collected. Hormone analyses were conducted on all samples utilizing liquid chromatography–tandem mass spectrometry.

Results

There were no significant differences in salivary hormone concentrations between the placenta and placebo groups post-supplementation that did not exist pre-supplementation. There were, however, significant dose–response relationships between the concentration of all 15 detected hormones in the placenta capsules and corresponding salivary hormone measures in placenta group participants not seen in the placebo group. The higher salivary concentrations of these hormones in the placenta group reflects the higher concentrations of these hormones in the placenta supplements, compared to the placebo.

Conclusions

Some hormones in encapsulated placenta lead to small but significant differences in hormonal profiles of women taking placenta capsules compared to those taking a placebo, although these dose–response changes were not sufficient to result in significant hormonal differences between groups. Whether modest hormonal changes due to placenta supplementation are associated with therapeutic postpartum effects, however, awaits further investigation.  相似文献

Background

Overseas-born-women from certain ethnicities are at high risk of type-2 diabetes and related metabolic disorders. This study explored the barriers and facilitators to long-term healthy lifestyle recommendations among Australian-born and overseas-born-women who attended health promotion sessions at a tertiary Australian Hospital for gestational diabetes 3–4 years previously.

Method

Face-to-face semi-structured interviews were conducted. Data were analyzed to identify major themes and the differing experiences of both groups of women.

Findings

Women in both groups faced many barriers to improve post-gestational-diabetes lifestyle. Women from both groups recalled healthy lifestyle recommendations for during pregnancy they received at the service, but had difficulty recalling the long-term lifestyle recommendations. Timing of the health information, non-reiteration of lifestyle recommendations, uncoordinated and fragmented health system support after childbirth were barriers faced by all women. Additional barriers for overseas-born women included the cultural competence of the health education material, their cultural preferences for food and physical activities and unsupportive family and partner. Both groups had excellent compliance with the first annual postnatal oral-glucose-tolerance-test. This was attributed to the personal motivation and health professional reminder. Women only reverted to the healthy lifestyles postnatally for weight loss.

Conclusion

A better understanding of the barriers to healthy lifestyle by women in their everyday lives will assist in the development of culturally appropriate health promotion guidelines and strategies. Constant un-fragmented postnatal engagement by the specialised diabetes clinics and primary health care services is crucial to sustain the healthy lifestyle in the long-term for women with previous gestational-diabetes.  相似文献

Objective: To develop a questionnaire for the differential diagnosis of detrusor underactivity (DUA) and bladder outlet obstruction (BOO) without performing invasive pressure flow studies.

Study design and methods: Symptoms of men with DUA were analyzed and compared with those of men with BOO using eight questions from the developing questionnaire. Patients with DUA have a bladder contractility index (PdetQmax+5xQmax) less than 100, whereas those with BOO have a BOO index (PdetQmax?2xQmax) greater than 40 in urodynamic studies (UDS). Men with detrusor overactivity in UDS and neurogenic issues were excluded from the analysis. One urologist reviewed patients’ medical records, and responded to eight questions without using information from UDS. Scores in the developing questionnaire were then compared to make a differential diagnosis between DUA and BOO.

Results: Overall, 318 men who underwent UDS were included. Symptoms were compared in patients diagnosed with DUA without BOO (n?=?165) and BOO without DUA (n?=?153). Questions 1, 2, 4, 5, 6, and 7 were significantly different between groups. The sensitivity and specificity of the questionnaire were 95.8% and 95.4%, respectively, for predicting DUA in patients with scores greater than 45 points (cutoff value).

Conclusions: Men with DUA and BOO may be distinguished using a developing questionnaire without invasive evaluation. Men with scores greater than 45 points would be expected to have DUA but not BOO.  相似文献

Gender inequality is a widespread organizational challenge, however, research on gender in the workplace suffers from stagnation in mainstream management research. A positive work and organizations perspective has the capacity to augment problem‐focused gender research with new approaches to boosting gender equity. Yet, contributions that utilize such a perspective are sparsely spread across nearly two decades’ time and dozens of journals with differing disciplinary foci. This paper aims to reinvigorate gender research in management research by consolidating insights that have emerged through the application of a positive perspective. Therefore, we systematically review articles published in 21 management and psychological journals between 2001 and 2016. Four main themes emerged as drivers of gender research from a positive perspective: performance, social integration, well‐being, and justice/moral matters. The contributions within these themes highlight pathways to organizational flourishing through positive diversity and inclusion behaviors and practices. Thus, this paper provides a conceptual map for navigating and planning further research.  相似文献

A considerable body of research has found a positive relationship between parents’ socioeconomic status and children’s educational achievement and attainment. The predictive role of parents’ socioeconomic status generally applies for most racial and ethnic groups, but that association does not always hold for groups that exhibit high levels of education, such as Asian Americans. This article considers the role of parents’ education and occupation on children’s educational and occupational attainment for Chinese Americans aged 18–32. The results corroborate the positive link between parents’ socioeconomic status and children’s educational and occupational attainments. Children of professionals command an educational and occupational advantage over children of entrepreneurs and children of manual workers. Yet, the children of entrepreneurs attend selective colleges and obtain professional occupations in proportions closely following those of the children of professionals. Although the educational attainments between the fathers who worked as entrepreneurs and those fathers engaged in manual work were comparable, it was the children of entrepreneurs who surpassed the children of manual workers with respect to educational and occupational achievement and attainment. This suggests that immigrant entrepreneurship contributes in the upward educational and occupational mobility of the children of entrepreneurs.  相似文献
