Making sustainable sourcing decisions: practical evidence from the automotive industry

Achieving environmental and sustainable performance within an organisation’s supply chain and manufacturing operations will be feasible if upstream supply partners have the same commitments in performing their operations in a sustainable manner. Given the debate above, we propose a comprehensive framework to address the sustainable supplier selection and order allocation (SSS&OA) problem. The framework developed is practical, that starts by using an audition check-list specific for each sustainability dimension (environmental, economic and social), from which the weighted values of its comprised criteria are obtained. The weighted scores of the selected sustainable suppliers are utilised by a proposed bi-objective order allocation model in order to make sourcing decisions. The strength of the proposed framework is its practical applicability to provide a solution for SSS&OA problems which is validated through a real-world application. Finally, research findings, theoretical and managerial insights and also directions for additional research are presented.     

Comments on Warren Samuels's "Why the Georgist Movement Has Not Succeeded"

A BSTRACT . The 16^th Amendment and the formation of the European Union were major political/economic reforms that should be seen as affirmations of the fundamental principles and teachings of Henry George. That these are not matters of interest to the self-defined Georgist movement reveals an excessively narrow focus of that movement and suggests its members' unfamiliarity with much of George's teachings.     

Using meta‐analytic structural equation modeling to advance strategic management research: Guidelines and an empirical illustration via the strategic leadership‐performance relationship

This paper demonstrates how meta‐analysis can be combined with structural equation modeling (MASEM) to address new questions in strategic management research. We review this integration, describe its implementation, and compare findings from bivariate meta‐analyses, a direct‐effect structural equations model, and two mediating frameworks using data on the strategic leadership and performance relationship. Results drawn from 208 articles that collectively included data on 495,638 observations demonstrate the new insights available from MASEM while also suggesting a revision to conventional thinking on strategic leadership. Whereas some theories posit that boards of directors influence firm performance through monitoring and disciplining the top management team, MASEM provides more support for the view that boards mediate the top management teams' decisions. Implications for applying MASEM in strategic management are offered. Copyright © 2014 John Wiley & Sons, Ltd.     

The impact of CEO core self‐evaluation on the firm's entrepreneurial orientation

Although much has been attributed to a CEO's personality, one particularly intriguing, and as yet unexplored, investigation is its impact on the firm's entrepreneurial orientation. Additionally, despite calls from the upper‐echelon literature, CEO personality research has been hobbled by the absence of a unifying construct that captures core dimensions of personality, and by the difficulty in obtaining such intimate assessments from executives. Building on recent advances in personality research, in particular the identification and validation of the core self‐evaluation construct that captures the core facets of an executive's sense of self‐potency, we develop and test a model of the impact of CEO core self‐evaluation on entrepreneurial orientation. Then, consistent with upper echelons and personality theory, we specify the contingent role of environmental dynamism. Using multisource data from a sample of CEOs and their top management teams from 129 firms, including a time‐lagged assessment of the firm's entrepreneurial orientation, we find evidence to suggest that CEOs whose personalities reflect higher core self‐evaluations have a stronger positive influence on their firms' entrepreneurial orientation. In addition, we find that this influence is particularly strong in firms facing dynamic environments, but negligible in stable environments. Copyright © 2009 John Wiley & Sons, Ltd.     

Patterns of Property Tax Exploitation Produced By Infrequent Assessments

A bstract . Out of dace assessments of real property for ad valorem taxation may give rise to systematic inequities in the distribution of the tax burden. One such inequity is the exploitation of a taxing jurisdiction's core area by its periphery. We provide an explanation of how such exploitation may arise. This explanation is tested empirically by observing the patterns of assessment in a sample of Pennsylvania school districts. We find a consistent pattern of overpayments, supporting an hypothesis that core areas are exploited by peripheral areas. The overpayments to school districts could be claimed by city governments.     

Statistical Inference,Learning and Models in Big Data

The need for new methods to deal with big data is a common theme in most scientific fields, although its definition tends to vary with the context. Statistical ideas are an essential part of this, and as a partial response, a thematic program on statistical inference, learning and models in big data was held in 2015 in Canada, under the general direction of the Canadian Statistical Sciences Institute, with major funding from, and most activities located at, the Fields Institute for Research in Mathematical Sciences. This paper gives an overview of the topics covered, describing challenges and strategies that seem common to many different areas of application and including some examples of applications to make these challenges and strategies more concrete.     

Contract costing in outsourcing enterprises: Exploring the benefits of discrete-event simulation

Outsourcing is a business strategy that has received much attention. An increase in outsourcing has a direct influence on the complexity of supply chain networks and on the number of contracts required to manage a supply chain. Outsourcing contracts may be entered into relatively quickly without a full understanding of the true cost implications. The research described here aims to develop tools based on discrete-event simulation to aid outsourcing companies when costing contracts. Currently available software for this type of application is reviewed. A field study is presented from the electronics sector, describing companies’ needs with respect to contract costing and how simulation could be used in the contract costing process. Simulation approaches are described for different contract costing scenarios. The paper concludes with a case study of a preliminary simulation model that has been developed to test the concept with a specific outsourcing scenario.     

Recreational demand for farm commonage in Ireland: A contingent valuation assessment

This paper measures willingness to pay (WTP) for public access and trail improvements on commonage farmland for recreational walking in upland and lowland areas of Connemara region in the West of Ireland using the contingent valuation method (CVM). Common to both upland and lowland commonage sites was the much higher ranking for infrastructural features by those WTP for scenario implementation compared to those preferring the status quo. Results for those expressing a positive WTP reveal a median willingness to pay (MWTP) for formal access with improved trail infrastructure of €12.22 for the lowlands compared with €9.08 for the uplands.     

Measuring progress in agricultural sustainability to support policy-making

The concept of sustainability is one of the forefront issues in discussions of the challenges facing global agriculture, given the mounting pressure to increase food production in both socially responsible and environmentally friendly ways. From the perspective of Irish agriculture, sustainable intensification is of particular relevance, given ambitious targets to increase milk production in the context of European Union (EU) milk quota removal in 2015. A series of farm-level sustainability indicators are developed here using the Teagasc National Farm Survey FADN (Farm Accountancy Data Network) data for Ireland from 2012. Three dimensions, reflecting the multifaceted nature of sustainability (environmental, economic and social) are considered. Given the environmental challenges inherent in the sustainable intensification of agriculture, it is encouraging to observe that the more intensive, top performing farms (in an economic sense) emit relatively less greenhouse gases when compared to their less intensive counterparts. Conversely, the better performing farms in economic terms tend to have a higher nitrogen surplus per hectare on average. This is consistent with their higher rates of production intensity, but poses a challenge in terms of sustainable intensification and expansion. That said this analysis demonstrates that the nitrogen use efficiency of milk production is positively correlated with economic performance, with more intensive farms producing relatively more milk per kilogram of nitrogen surplus. From the perspective of social sustainability, demographic traits also tend to be positively correlated with economic performance. Given a growing recognition of the need for interconnected policy in the area of sustainability, this research should help inform policy debates and provides a guide for the undertaking of similar assessments elsewhere.
