Health-care Provider Compassionate Love and Women's Infertility Stressors

The purpose of the present study was to examine relationships between doctor compassionate love and treatment, relational, and psychological stressors, as well as to identify effective health-care provider compassionate messages. Participants were 233 women who had been treated for infertility in the past 12 months. Doctor compassionate love was directly associated with positive affect during treatment, perceived treatment stress, and self-esteem. Additionally, perceived treatment stress mediated the relationship between doctor compassionate love and social and marital stress, as well as self-esteem and depression. Participants identified five categories of memorable compassionate messages sent by health-care providers, including offering hope, privileging the patient ahead of the self, practicing patient-centeredness, empathizing, and nonverbally communicating. Messages that constituted privileging the patient ahead of the self and nonverbally communicating were significantly more compassionate than those of offering hope. The study provides implications for the clinical treatment of infertile women and a practical tool for doing so compassionately.

Impact sports and bone fractures among adolescents

The objective of the present study was to investigate the effects of different sports on stress fractures among adolescents during a 9-month follow-up period. The sample was composed of 184 adolescents divided into three groups (impact sports [n = 102]; swimming [n = 35]; non-sports [n = 47]). The occurrence of stress fracture was reported by participants and coaches. As potential confounders we considered age, sex, resistance training, body composition variables and age at peak of height velocity. There were 13 adolescents who reported fractures during the 9-month period. Bone mineral density values were higher in adolescents engaged in impact sports (P-value = 0.002). Independently of confounders, the risk of stress fracture was lower in adolescents engaged in impact sports than in non-active adolescents (hazard ratio [HR] = 0.23 [95% confidence interval (CI) = 0.05 to 0.98]), while swimming practice was not associated to lower risk of fracture (HR = 0.49 [95% CI = 0.09 to 2.55]). In conclusion, the findings from this study indicate the importance of sports participation among adolescents in the reduction of stress fracture risk, especially with impact sports. More importantly, these results could be relevant for recognising adolescents in danger of not reaching their potential for peak bone mass and later an increased risk of fractures.     

Team intuition as a continuum construct and new product creativity: The role of environmental turbulence, team experience, and stress

Although past research has reported the benefits of intuition in new product decision-making (i.e., higher quality product; enhanced customer satisfaction), intuition has largely been studied as an individual phenomenon and little work has examined the role of intuition on new product development (NPD) project teams. Furthermore, in a turbulent environment, NPD project teams may rely more on intuitive judgments, and other factors such as experience and stress may also influence the relationship between team intuition and team decision making. Drawing from the organizational design literature on creativity in decision making, this study builds a conceptual model of NPD team intuition and its effect on the team's ability to generate creative new products. We then derive hypotheses regarding team intuition, stress, environmental turbulence, and new product creativity, and test the hypotheses using data from a sample of 155 firms operating in Ankara and Istanbul, Turkey. We specifically test whether an inverted-U relationship exists between team intuition and new product creativity (that is, a balance of both intuitive and rational judgments is preferred), and whether this relationship is moderated by team experience and stress. Moreover, direct impact of turbulent conditions (i.e. market and technical turbulence) on intuition was also examined. The results of our empirical study with a sample of 310 new product/project developers and 155 project managers showed a positive and linear relation between turbulent conditions (both market and technical) and team intuition and an inverted U-shaped team intuition-new product creativity relation for teams with high experience and low stress. Finally, theoretical implications for future research and managerial implications for practitioners are discussed in the conclusion section.
