Green supply chain management practices and firm performance: evidence from Finland

In order to address the increasing stakeholder requirements for environmentally sustainable products and processes, firms often need the participation of their supply chain partners. Green supply chain management has emerged as a set of managerial practices that integrate environmental issues into supply chain management. If implemented successfully, green supply chain management can be a way to achieve competitive advantage while enhancing the environmental sustainability of the firm. The overall purpose of this dissertation is to contribute to the discussion on green supply chain management practices from the perspective of their drivers and performance implications. The theoretical background arises from the literature on competitive strategy, firm performance and green supply chain management. The research questions are addressed by analysing firm-level data from manufacturing, trading and logistics firms operating in Finland. The empirical data comes from two consecutive Finland State of Logistics surveys in 2012 and 2014, combined with financial reporting data from external databases. The data is analysed with multiple statistical methods. First, the thesis contributes to the discussion of the drivers of GSCM practices. To enhance the understanding of the relationship between competitive strategy and GSCM practices, a conceptual tool to describe generic competitive strategy approaches was developed. The findings suggest that firms pursuing marketing differentiation are more likely to be able to compete by having only small environmental effects and by adopting a more advanced form of external green supply chain management, such as a combination of strong environmental collaboration and the increased environmental monitoring of suppliers. Furthermore, customer requirements for environmental sustainability are found to be an important driver in the implementation of internal GSCM practices. Firms can respond to this customer pressure by passing environmental requirements on to their suppliers, either through environmental collaboration or environmental monitoring. Second, this thesis adds value to the existing literature on the effects of green supply chain management practices on firm performance. The thesis provides support for the idea that there is a positive relationship between GSCM practices and firm performance and enhances the understanding of how different types of GSCM practices are related to 1) financial, 2) operational and 3) environmental performance in manufacturing and logistics. The empirical results suggest that while internal GSCM practices have the strongest effect on environmentalperformance, environmental collaboration with customers seems to be the most effective way to improve financial performance. In terms of operational performance, the findings were more mixed, suggesting that the operational performance of firms is more likely to be affected by firm characteristics than by the choices they make regarding their environmental collaboration. This thesis is also one of the first attempts to empirically analyse the relationship between GSCM practices and performance among logistics service providers. The findings also have managerial relevance. Management, especially in manufacturing and logistics industries, may benefit by gaining knowledge about which types of GSCM practice could provide the largest benefits in terms of different performance dimensions. This thesis also has implications for policy-makers and regulators regarding how to promote environmentally friendly activities among 1) manufacturing; 2) trading; and 3) logistics firms.

Parental influences and mothers’ experiences on infant and young child feeding practices

The objective of this thesis was to better understand how parental factors influence feeding practices, how mothers experience feeding and what factors mothers perceive influencing feeding in different contexts. This study is largely based on STEPS Study (Steps to Healthy Development of Children), which is a longitudinal cohort of 1797 families. In addition, qualitative data was collected among mothers in Finland and Solomon Islands. The results of this study show that different parental determinants associate with infant and young child feeding behavior and practices. Mothers with high cognitive restraint of eating introduced complementary foods earlier and neophobic mothers’ breastfed exclusively for a shorter time than mothers who ranked lower in these behaviors. Fathers’ poor diet quality associated with shorter total breastfeeding duration. Mothers’ postnatal depressive symptoms associated with shorter duration of exclusive breastfeeding, earlier introduction of complementary foods and lower compliance of feeding recommendations. The higher amount of marital distress associated with longer duration of exclusive breastfeeding and better compliance with feeding recommendations. Mothers, who participated in qualitative interviews, described how complex interplay of individual perceptions, significant others and socio-cultural environment influenced feeding practices and behavior. This study showed that several parental factors influence infant and young child feeding practices as well as compliance with the feeding recommendations. Maternal experiences and perceptions on child feeding relate to the context where mother-infant pair lives in. These results highlight the importance of targeting feeding support and, if needed, specific interventions to mothers and families who are in risk of poor feeding practices.
