This paper reinvestigates the relationship between urbanization and energy consumption in case of Pakistan for the period of 1972Q1-2011Q4 by employing the STIRPAT (Stochastic Impact by Regression on Population, Affluence and Technology) model. We have employed the ARDL bounds testing approach to cointegration in the presence of structural breaks stemming in the series to count for these missing elements in other studies. Finally, the VECM Granger causality approach has been applied to examine the causal relationship between the variables. Our results show that urbanization adds in energy consumption. Affluence (economic growth) increases energy demand. Technology has positive impact on energy consumption. An increase in transportation is positively linked with energy consumption. The causality analysis indicates the unidirectional causality running from urbanization to energy consumption. © 2017 Elsevier Ltd

This article examines farmers' preferences for both cropping and management practices, which are of policy interest because of their environmental impact. We present the results of a choice experiment survey of all agricultural decision makers in the Camargue region. A latent class model identified three classes. The main class encompasses farmers complying with the norms of the Protected Geographical Indication (PGI): Riz de Camargue. We estimated the monetary value of each of the relevant agricultural practices. Our results make a strong case for differentiating incentives to encourage environmentally friendly practices and identify the diversity of values attached to the main components of rice cropping technology in the area. Estimates of the implicit prices indicate that most rice growers can be persuaded to adopt environmentally friendly practices. These findings could help in designing targeted contracts according to farmers' preferences, in line with conservation or environmental objectives. © 2013 The Agricultural Economics Society.

We consider a periodic review perishable inventory system. Item lifetimes are random and assumed to follow an Erlang distribution. This is a rich modeling allowing us to cover various cases of lifetime variability in practice. The demand process is assumed to be Poisson and the order lead time is constant. For the extreme cases of exponential and deterministic lifetimes, we provide an analytical approach for the system performance evaluation. We also conduct a simulation study to examine the important effect of lifetime variability mixed with the cost parameters on the total operating cost. It appeared that there might be opportunities to considerably improve the operating cost in the case of high lifetime variability. This is more apparent for cases with large outdate, lost sale, and purchasing cost parameters. © 2015 Elsevier B.V. All rights reserved.

This article investigates the relationships between various types of educational value generated by the Markstrat simulation game. Considering several theoretical models of experiential learning and the research framework proposed by previous studies, an educational value generation model is developed and validated, using primary data collected from 305 UK-based students. Four types of educational value are identified: experience generation, conceptual understanding, skills development, and affective evaluation. The application of structural equation modelling indicates several significant relationships: experience generation has a strong impact on conceptual understanding, and both of them have medium to high direct impacts on skills development. On the other hand, the participants' perception regarding the professional skills developed during the simulation game determines their affective evaluation of the Markstrat exercise. The model presented in this study is generalizable to other simulation games, and to other academic disciplines that implement the same experiential learning approach. © 2014 Elsevier Inc.

Although widely used by brands to communicate an exotic origin, exotypes have never been studied in the marketing literature. This research presents the exotype family of typefaces and then uses semiotic models to examine its power to evoke foreign cultures. One experiment is conducted among 1718 questionnaire respondents in order to study consumer perceptions of six exotypes. The results show that exotypes are able to communicate a specific exotic origin, especially when the connoted meaning of the typeface is congruent with the denoted meaning of the text. © 2014 Elsevier Ltd.

Purpose: The purpose of this paper is to explore consequences of the use of social media for idea generation. Design/methodology/approach: The paper analyzes over 600 ideas submitted to a Slate-Twitter contest to find the best short characterization of the American Declaration of Independence. These findings are then compared with those of Kornish and Ulrich, who analyzed idea-contests in classroom settings. Findings: In the Slate-Twitter contest, repetition of ideas was rare while recombination was frequent. The evolution in the total number of unique ideas suggests that the contest became more focused over time. It also appears that ideas that are recognized as valuable attract similar ideas in turn. Research limitations/implications: Further checks will be needed with regard to the robustness of the findings. Furthermore, while the current analysis relies on peer review by participants to the contest to value submissions, results might be different if it were done on the basis of independent external reviews. Conceptually, the findings suggest that idea generation via social media has a more iterative character than previously analyzed forms of broadcast search. Future research could investigate what triggers more exploration and exploitation of ideas in this process. Practical implications: For businesses, which are more and more encouraged to engage in open innovation, the analysis can serve as guide on the use of social media for information collection. Originality/value: The paper provides a simple and effective method to monitor social media, which firms can use to their advantage. © Emerald Group Publishing Limited.

The objective of this paper is to provide an overview of the current state of theory and practice on valuing Knowledge-Based Initiatives (KBI). Drawing on the literature concerning IT and business value, this paper summarizes what is known about valuing IT-based initiatives, discusses the specificity of KBI and outlines main challenges that continue to limit research in this area. This paper also examines how managers deal with these challenges and what metrics they use to assess knowledge value. These managerial insights are derived from interviews as well as empirical analysis of several Silicon Valley firms. This paper gives an emerging approach for valuing KBI and illustrates its implementation with a case study from IBM. Copyright © 2011, IGI Global.

While many crop insurance systems have been reformed around the world, few academic researches have addressed the determinants of the decision on crop insurance at the farm's micro level. In this article, both the financial and the agricultural literature lead to the identification of many rationales for the crop insurance decision. Using data from the period 2003-2006 on a representative survey of French farms (FADN-RICA), we investigate the different factors that incite farmers to insure against crop risk. We emphasize that the highest risk farms are more likely to have insurance and this decision is positively related to the past amount of claims. Insurance is subscribed by larger farms because insurance appears too expensive for smaller farms, which are indeed naturally less diversified. Interestingly, financial variables (such as capital structure or return on investment) do not significantly determine the insurance decision. © 2011 International Association of Agricultural Economists.

Genetically-modified foods represent a potential solution of the world food crises, but they are also feared as potential dangers for human health, environment and biodiversity. Considering the history of genetically-modified foods and their present situation, this study develops and validates three complex scenarios regarding the future evolution of genetically-modified foods. The plausibility of these scenarios is tested using five food experts, as well as two demographically-representative groups of French and U.K. respondents. The present situation and potential evolution of genetically-modified foodsis also analyzed using the Innovation Diffusion Theory, as well as a Value-based Perspective. © 2016 Elsevier Ltd

A complex country such as India whose trajectory has been unique in history compared to Europe or China or the USA, poses the possibility of many scenarios that could emerge in the latter half of the 21st Century. This paper looks at a range of issues from, governance and education to the environment and culture. The paper considers how the past could shape the country in 2050, together with changes in technology, better governance and environmental awareness. The move towards globalization is relentless and the paper indicates the role India could play in world trade, world food production and governance. In the end this is a fairly optimistic view of what could be possibly achieved over the next 38 years. © 2013 Elsevier Ltd.
