Background An online health community (OHC) is a novel sharing channel through which doctors share professional health care knowledge with patients. While doctors have the authority to protect their patients’ privacy in OHCs, we have limited information on how doctors’ privacy protection choices affect their professional health care knowledge sharing with patients. Objective We examined the relationship between privacy protection and professional health care knowledge sharing in OHCs. Specifically, we examined the effects of privacy protection settings in an OHC on doctors’ interactive professional health care knowledge sharing and searching professional health care knowledge sharing (two dimensions of professional health care knowledge sharing). Moreover, we explored how such effects differ across different levels of disease stigma. Methods We collected the monthly panel data of 19,456 doctors from Good Doctor, one of the largest OHCs in China, from January 2008 to April 2016. A natural experimental empirical study with difference-in-difference analysis was conducted to test our hypotheses. The time fixed effect and the individual fixed effect were both considered to better identify the effects of a privacy protection setting on professional health care knowledge sharing. Additionally, a cross-sectional analysis was performed for a robust check. Results The results indicate that the privacy protection setting has a significant positive effect on interactive professional health care knowledge sharing (β=.123, P<.001). However, the privacy protection setting has a significant negative effect on searching professional health care knowledge sharing (β=–.225, P=.05). Moreover, we found that high disease stigma positively impacts the effect of privacy protection on interactive professional health care knowledge sharing (coefficients are in the same valence) and negatively impacts the effects of privacy protection on searching professional health care knowledge sharing (coefficients are in the reverse valence). Conclusions Privacy protection has a bilateral effect on professional health care knowledge sharing (ie, a positive effect on interactive professional health care knowledge sharing and a negative effect on searching professional health care knowledge sharing). Such bilateral switches of professional health care knowledge sharing call for a balanced state in conjunction with practical implications. This research also identifies a moderate effect of disease stigma on privacy protection settings and professional health care knowledge sharing.

BACKGROUND Online health knowledge-sharing platforms (OHKSPs) play an increasingly important role in enriching residents’ health knowledge, thus improving their health behaviors. The participation of physicians determines whether the platforms can provide high-quality health knowledge to the public. However, little research has focused on motivating physicians to share more professional health knowledge on the platforms. Understanding physicians’ behavioral intention for professional health knowledge sharing (PHKS) is essential to support the development of OHKSPs and improve public health. OBJECTIVE We examine the relationship between incentives and PHKS in OHKSPs. Specifically, we explore the effects of incentives with different complexities in an OHKSP on the quantity and quality of PHKS. We explore how such effects differ across varying levels of professional titles. METHODS We conducted four field experiments with different incentive strategies in one of China's largest OHKSPs. Monthly panel data of 10,584 physicians were collected from January 2018 to December 2019. An empirical study with a fixed-effect analysis was conducted to test our hypotheses. The time fixed effect and the individual fixed effect were considered to identify incentives' effects on physicians’ PHKS. Additionally, a cross-sectional analysis was performed for a robustness check. RESULTS The results show that the incentive has a significant positive effect on the quantity of physicians’ PHKS (β=0.50012, 0.35167, 0.28337, 0.22899; p<0.01). However, the incentive has a significant negative effect on the quality of physicians’ PHKS (β=-0.12911, -0.12039, -0.10948, -0.07933; p<0.01). We found that the positive effect of incentives with high complexity on the quantity of physicians’ PHKS is significantly smaller than incentives with low complexity (0.22899<0.50012, p<0.01). The absolute value of the negative effect of incentives with high complexity on the quality of physicians’ PHKS is also significantly smaller than incentives with low complexity (-0.12911<-0.07933, p<0.01). Moreover, we found that high professional title positively impacts the effect of incentives with low complexity on both the quantity and the quality of physicians’ PHKS (coefficients are in the same valence). CONCLUSIONS Incentives have a bilateral effect on PHKS, i.e., a positive effect on the quantity of physicians’ contribution and a negative effect on the quality of physicians’ PHKS. Such bilateral switches of PHKS require a balanced state in conjunction with practical implications. Furthermore, the more complex the incentives are, the more inefficient the effects on physicians’ PHKS are. This research also identifies a moderate effect of professional titles on incentives and physicians’ PHKS.

The paper aims to assess the impact of the COVID-19 pandemic and possible future global epidemic events on shopping behavioral patterns. Specifically, the paper investigates consumer pandemic-related isolation behavior (which manifests itself via preference for shopping without leaving home, and avoiding contact with other people while shopping offline) as a consequence of consumer interdependent self-construal, with the mediating role of consumer pandemic-related emotions of disgust, fear for oneself, fear for others, and sadness. The results of two surveys conducted in different stages of the COVID-19 pandemic in Poland (October 2020, and January 2021, respectively) suggest two opposing indirect effects of interdependent self-construal on isolation behavior: a positive effect through disgust, and a negative effect through sadness. Additionally, a positive indirect effect through fear was visible in the second study. Moreover, two dimensions of interdependent self-construal (i.e., vertical and horizontal) are demonstrated to have opposing effects (a positive effect and a negative one, respectively) on pandemic-related disgust, and in turn on isolation behavior. The above results indicate that, in the context of the pandemic, consumer self-construal influences pandemic-related emotions, and in turn consumers’ tendency to isolate themselves. Implications for marketers and society were discussed from the perspective of economic and sustainability goals.

This study presents a systematic approach that integrates the information adoption model (IAM) with topic modeling to analyze the digital voice of users in online open innovation communities (OOICs) and empirically examines the usefulness of UGC with large amounts of redundant information and varying content quality across two dimensions: information quality and information source credibility. A total of 61,227 bug comments were collected from the OOIC of Huawei EMUI and analyzed using binary logistic regression. The results show that information timeliness and completeness have a positive effect on the usefulness of UGC in OOICs; conversely, information semantics have a negative effect on the usefulness of UGC. Prior user experience has no influence on the usefulness of UGC in OOICs, while active user contribution has a positive effect on the usefulness of UGC. The results of this study offer several implications to researchers and practitioners, and thus could serve as a pivotal reference source for further investigation of potential determinants of UGC usefulness in OOICs.

Important Means

Knowledge sharing among teachers denotes an important means of promoting the professional growth of individual instructors. It enhances the competitiveness of school organizations and thus constitutes a focal aspect of knowledge management in universities. This study conducts an in-depth scrutiny of the knowledge sharing behaviors of teachers, examining their sharing intentions and attitude, support received from others, self-control. With this aim, this paper obtains data from 440 college teachers in Jiangxi Province in China. It then constructs a theoretical model reflecting these factors, and the collected data were analyzed through SPSS24 and AMOS24 to obtain the results. The results of this empirical study conducted in China demonstrate that the knowledge sharing intentions of teachers positively influence their knowledge sharing behaviors. Personal knowledge sharing attitudes and support received from others also constructively affect the knowledge sharing intentions of teachers. Self-control has a negative effect on knowledge sharing intentions and exerts an indirect influence on knowledge sharing behaviors. Knowledge sharing attitudes, support received from others, and self-control are strongly and positively correlated. This investigation suggests that the knowledge sharing intentions of teachers must first be enhanced to improve their knowledge sharing behaviors. The enthusiasm of teachers to share knowledge should be stimulated, and teachers should be encouraged to freely share their understanding with others. Further, their tight regulation of self-control should be appropriately relaxed.

Institutional barriers frustrate third-party challenges to major-party dominance in American politics. Conventional wisdom claims that the ballot access petitioning requirement hurts minor parties. This claim, however, conflates two dimensions of third-party success: (a) ability to get on the ballot and (b) ability of actual candidates to win votes. The requirement is hypothesized to have a negative effect on the first dimension but a positive effect on the second. Modeling these two dimensions separately gives evidence of cross-cutting effects. The first equation is a probit model of entry that shows third-party candidates are more likely to enter when the requirement is low. The second equation is an OLS regression, which only includes the subsample of districts where at least one third-party candidate gained ballot access, that shows third-party candidates win more votes in districts with a higher requirement.

In this study, we test the effects of retrenchment aggressiveness on turnaround performance. Using the downward-spiral, threat–rigidity, and survivor syndrome perspectives, we hypothesize the direct effects of the two dimensions of aggressiveness—time aggressiveness and volume aggressiveness—on turnaround performance. We also examine the moderation effect of time aggressiveness on the relationship between volume aggressiveness and turnaround performance. We use data on a sample of declining firms collected from the Compustat North America database and use a matched-pair sample of 494 surviving and nonsurviving firms between the years 1990 and 2010. Our results show that time aggressiveness has a positive effect on turnaround performance, whereas volume aggressiveness has a negative effect. We also find that time aggressiveness positively moderates the negative relationship between volume aggressiveness and turnaround performance. We contribute to the scant but critical literature indicating the importance of time in a turnaround setting and to the long-held discussion of retrenchment as a cause of turnaround or a consequence of decline.

Active Assistance

Anyone who has ever prepared a college of nursing catalogue has had to engage, if only briefly and superficially, in the development of a philosophy of nursing. I would like to carry that activity a little further here in order to propose and develop a particular philosophy of nursing.I will describe what could be called the self care philosophy. But an important distinction must be made at the outset. “Self care” usually suggests the lay revolt against professional care; often, self care is billed as an alternative to rather than a philosophy of professional health care. What then do we mean by self care as a philosophy of nursing? The philosophy is this: that nursing have as its primary ideal active assistance to individuals, families, and communities in the development and exercise of their autonomy in health matters. The concept of self care, or patient autonomy, involves two dimensions, action and agency, and the nurse provides assistance in both of these. Self care action is the health behavior that is performed.
