This paper aims to empirically analyze how adaptive collaboration in supply chain management impacts demand forecast accuracy in short life-cycle products, depending on collaboration intensity, product life-cycle stage, retailer type and product category.

The authors assembled a data set of forecasts and sales of 169 still-camera models, made by the same manufacturer and sold by three different retailers in France over five years. Collaboration intensity, coded by collaborative planning forecasting and replenishment level, was used to analyze the main effects and specific interaction effects of all variables using ANOVA and ordered feature evaluation analysis (OFEA).

The findings lend empirical support to the long-standing assumption that supply chain collaboration intensity increases demand forecast accuracy and that product maturation also increases forecast accuracy even in short life-cycle products. Furthermore, the findings show that it is particularly the lack of collaboration that causes negative effects on forecast accuracy, while positive interaction effects are only found for life cycle stage and product category.

Investment in adaptive supply chain collaboration is shown to increase demand forecast accuracy. However, the choice of collaboration intensity should account for life cycle stage, retailer type and product category.

This paper provides empirical support for the adaptive collaboration concept, exploring not only the actual benefits but also the way it is achieved in the context of innovative products with short life cycles. The authors used a real-world data set and pushed its statistical analysis to a new level of detail using OFEA.

The evaluation of emotional management in police environments has impacts on their health and on their interventions (Monier, 2014; Van Hoorebeke, 2003). There are significant costs related to occupational diseases in the police force: absenteeism, turnover, deterioration of the work climate (Al Ali et al., 2012). Considering that policing involves a high level of emotional control and management (Monier, 2014; Al Ali et al., 2012; Dar, 2011) and that no study has yet examined the relationship between police officers’ emotional competencies and their psychological health at work (PHW), the purpose of this paper is to explore the relationship and influence of emotional self-efficacy (ESE) on PHW in policing.

PHW results from psychological distress at work (PDW) (irritability, anxiety, disengagement) and psychological well-being at work (PWBW) (social harmony, serenity and commitment at work) (Gilbert et al., 2011). ESE is defined as the individual’s belief in his or her own emotional skills and effectiveness in producing desired results (Bandura, 1997), conceptualized through seven emotional skills: the use of emotions; the perception of one’s own emotions and that of others; the understanding of one’s emotions and that of others; and the management of one’s emotions and that of others (Deschênes et al., 2016). A correlational estimate was used with a sample of 990 employed police officers, 26 percent of whom were under 34 years of age and 74 percent over 35. The ESE scales (a=0.97) of Deschênes et al. (2018) and Gilbert et al. (2011) on PWBW (a=0.91) and PDW (a=0.94) are used to measure the concepts under study.

The results of the regression analyses confirm links between police officers’ emotional skills and PHW. The results show that self-efficacy in managing emotions, self-efficacy in managing emotions that others feel, self-efficacy in using emotions and self-efficacy in understanding emotions partially explain PWBW (R²=0.30, p<0.001). On the other hand, self-efficacy in perceiving the emotions that others feel, self-efficacy in using emotions and self-efficacy in managing emotions partially explain PDW (R²=0.30, p<0.001).

This study provided an understanding of the correlation between police officers’ feelings of ESE and their PHW, particularly with PWBW. Beyond the innovation and theoretical contribution of such a study on the police environment, the results reveal the scope of the consideration of emotional skills in this profession.
