This article aims to quantify to what extent collaborative strategies are more effective than internal or organization‐level actions to green supply chains. In this regard, the impact of decisions made at different stages of a supply chain in a product's carbon footprint is quantified. Organizational and product carbon footprints are calculated using the Compound Method Based on Financial Accounts (MC3). The results underline that concentrating reduction efforts in some stages of the supply chain is more effective than implementing individual actions by the participants. Collaboration among the participants is needed to decide what practices are implemented, at what stage they are needed and how they are to be implemented. This article adds to the literature on supply chains and sustainability. Previous research suggests that collaborative strategies have great potential for reducing the carbon footprint of products, while indicating the need for empirical research to support this statement.

Learner-centred approaches follow the prevailing tendency in modern University reforms which are primarily concerned about
“how people learn”. The methodologies can be learner-centred in the sense of placing the student as the main actor of the
teaching–learning process by increasing his interactivity and participation, but also considering what is relevant for the
student by measuring the learner satisfaction. In order to promote both aspects, this paper proposes a synchronous software-based
active methodology that makes use of the simulations to show a virtual scenario to the students and challenge them to predict
and discuss the evolution of the scenario. The proposed methodology improves the visual interface, promotes discussion both
among students and with the teacher in a brainstorming stage and shows real-world examples. This software-based methodology
has been implemented into an Electric Machinery course at the University of Seville (Spain), and the evaluation has been carried
out considering both the affective and cognitive domains. Principal components analysis proves to be useful to highlight the
dimensions with a higher influence on learner satisfaction and the affective and cognitive results confirm the successful
implementation of the proposal. 相似文献

This study empirically analyses the effect that the bankruptcy law has on firms’ performance based on its financial situation. To do this, we considered the different types of efficiency and their influence on firms’ value. The study was carried out for Germany, Spain, the United States, France and the United Kingdom. We applied System‐GMM estimation to dynamic panel data. The main results show that under creditor‐oriented systems, there is a decrease in the value of both financially distressed firms and those filing for bankruptcy. 相似文献

This study analysed motorcycle crashes in Spain. Ninety-nine thousand three hundred and four motorcycle crash reports filed in the years 2006–2011 were extracted from the Directorate General of Traffic database of crashes with victims. These data were analysed in terms of gender, age groups, trip purpose, type of crash, speed violation, day of the week, harm caused, use of helmet and psychophysical conditions of the driver to study the characteristics of motorcycle crashes in Spain and to assess the differences between male and female motorcycle drivers in these crashes. Significant differences were found in all the variables considered in the study, which implies gender differences in the profile of the injured motorcycle driver. The severity of motorcycle crashes suffered by male drivers is higher than that of women. These results corroborate the need to develop measures differentiated by gender, based on their profile. 相似文献

abstract Previous research has portrayed buyer–supplier and supplier–supplier alliances as important mechanisms to foster learning and exchange efficiencies. Controversy remains, however, as to how these alliances interact. While some propose they reinforce one another (e.g. learning in horizontal ties generates positive spillovers to vertical ties), others propose a negative interplay (e.g. when increasing vertical-tie intensity, suppliers may weaken horizontal ties to avoid retaliation from buyers who wish to preserve bargaining power). We empirically test these competing views using survey data from the Brazilian auto-parts industry. In an attempt at reconciliation, we propose that the positive or negative interaction between vertical and horizontal alliances depends on the level of technological uncertainty of goods exchanged. Vertical ties seem to inhibit horizontal ties when technological uncertainty is low; when technological uncertainty is higher, vertical and horizontal ties do not seem to have any meaningful form of interaction. We discuss implications for theory and practice. 相似文献

This paper proposes a stylized two‐period, two‐country model illustrating the role of distribution of domestic wealth in determining a country's level of access to international lending. We model sovereign debt redemption policy in a common agency framework. Within this framework, policy is the outcome of the interaction between government and local and foreign interest groups with conflicting preferences on debt repayment. Our main result is that in full lobby competition, when all interests are represented, the only equilibrium solution is repudiation and the consequent inability of government to access international capital markets. Conversely, when the ability to lobby depends on wealth, governments can access international credit up to a given maximum external debt capacity, determined by the skew in the distribution of domestic wealth. 相似文献

It is often assumed that the fight against inequality played an important role in the rise of the welfare state. However, using social transfers as an indicator of redistribution and three alternative proxies for inequality—the top income shares, the ratio of the GDP per capita to the unskilled wage, and the share of non‐family farms—this article shows that inequality did not favour the development of social policy between 1880 and 1930. On the contrary, social policy developed more easily in countries that were previously more egalitarian, suggesting that unequal societies were in a sort of inequality trap, where inequality itself was an obstacle to redistribution. 相似文献

In contrast with previous index model land applications, this article shows that the land allocation problem is a portfolio model with two constraints, namely, investable funds and land. The two-constraint model implies a drastic reinterpretation of what previous studies have quantified as diversifiable and systematic risks in agricultural production. The article also argues that the constant marginal-rate-of-product-substitution (MRPS) technology implicit in financial portfolio models is unlikely to hold in a production context such as the land allocation problem, and that the index model must be modified accordingly. Farm-level data are used to illustrate and test the hypotheses advanced. Empirical results indicate that most of the risk for corn and soybeans is diversifiable, and that corn and soybeans are characterized by decreasing MRPS. The MRPS effect is found to be large from an economic standpoint and implies that crop diversification may be optimal, even for risk-neutral farmers. 相似文献

Roncaglia and Nell have criticised the interpretation of Sraffa's normal prices as centres of gravitation for actual prices. Roncaglia mainly focuses on the interpretation of the notion of gravitation in Smith and on the meaning of the ‘given outputs’ in Sraffa. Nell attempts to confine the relevance of Sraffa's theory to specific historical circumstances and to find a role for Sraffa's prices in his version of post-Keynesian price theory. This rejoinder criticises the case made by both Roncaglia and Nell, and defends Sraffa's centre of gravitation view. 相似文献
