The Impact of Green Supply Chain Management on Circular Economy Performance: The Mediating Roles of Green Innovations

Background: This study investigated the impact of green supply chain management (GSCM) on circular economy (CE) performance. The mediating roles of three green innovation types, namely green product innovation, green process innovation, and green management innovation, are also examined. Methods: This study’s population comprised all companies in the manufacturing sector in Jordan. A simple random method was applied to gather data from 278 companies. The research model was evaluated in terms of validity and reliability, which were found to be satisfactory. Hayes’s PROCESS macro in IBM SPSS was applied for hypothesis testing. Results: The findings showed that GSCM directly and positively affected CE performance. Moreover, GSCM showed positive impacts on the three types of green innovation. In addition, the three innovation types demonstrated positive impacts on CE performance and proved to positively mediate the GSCM–CE performance relationship. Conclusions: The present study is the first, to the best of our knowledge, to examine the mediating effect of green innovations on the GSCM–CE performance relationship. It is also among the first to examine the impact of GSCM on three different types of green innovation that represent technological and non-technological innovations

Evapotranspiração e coeficiente de cultivo do tomate caqui cultivado em ambiente protegido Evapotranspiration and crop coefficient of Kaki tomato cultivated in greenhouse

Os parâmetros aerodinâmicos de uma cultura cultivada em ambiente protegido podem ser considerados dependentes do nível de radiação global, temperatura do ar e umidade do ar, com base em leis exponenciais. Assim sendo se propôs com este trabalho, estimar a evapotranspiração e o coeficiente de cultivo da cultura do tomate caqui em ambiente protegido, sob irrigação por gotejamento, utilizando-se o modelo de Penman-Monteith. Os parâmetros aerodinâmicos foram medidos com sensores conectados à estação automática instalada dentro do ambiente protegido. A evapotranspiração da cultura (ETc) foi determinada experimentalmente por meio de lisímetros de drenagem e a umidade do solo foi medida através de sensores instalados a uma profundidade de 20 cm. O desempenho do modelo de Penman-Monteith foi comparado aos valores decendiais do balanço hídrico nos lisímetros; já a evapotranspiração de referência foi calculada com dados externos e utilizada para o cálculo do Kc da cultura; enfim, os resultados indicaram que o modelo de Penman-Monteith subestima os valores de evapotranspiração encontrados pelo balanço hídrico nos lisímetros.<br>The aerodynamic parameters of a crop cultivated in greenhouse can be considered dependent upon the level of global radiation, air temperature and relative humidity, based on exponential laws. Consequently, this work intends to estimate the evapotranspiration and the crop coefficient of Kaki tomato in greenhouse, under drip irrigation, using the Penman-Monteith model. The aerodynamic parameters were measured with sensors connected to the automatic station installed inside the greenhouse. The ETc was determined experimentally through drainage lysimeters and the soil water content was measured through sensors installed at a depth of 20 cm. The performance of the Penman-Monteith model was compared to decennial values of the water balance in the lysimeters, while the reference evapotranspiration was calculated with external data and used for calculation of crop Kc. The results indicated that the Penman-Monteith model underestimates the evapotranspiration values found by the water balance in the lysimeters
