A case study of kanban implementation within the pharmaceutical supply chain

This study explores the implementation of the kanban system, which is a Lean technique, within the pharmaceutical supply chain (PSC). The case study provides insights on the benefits and challenges arising from the application of this technique, within a group of cooperative pharmacists, in Greece. The research questions developed from the review of the literature were tested using evidence from field-based, action research within a pharmaceutical organisation. The reported case study contributes to the longer term debate on assessing the Lean maturity level within the health-care sector. There are two primary findings: (i) that the adoption of kanban system provides a strategic benefit and improves the quality of services. (ii) It also provides a basis for a strategy of operational change; it gives the opportunity to the organisation to move away from the current push delivery and logistics systems towards improved logistics strategy models.     

Transaction Costs of Entrepreneurs as a Deterrent of Housing Construction Development in Russia

Nowadays realization process of investment and construction projects is not always effective because of imperfection of institutions regulating construction, high investment risks and, as a consequence, increase transaction costs. The facts of the objective existence of transaction costs in the economy, including housing construction, are researched in the article. We have determined that the transaction costs significantly affect the cost of construction, reduce profit entrepreneurs, and indirectly increase the shortage of housing in Russia. Such parts of modern economics as neoclassical economics and institutional economics are methodological basis of the paper. Logical, economic and legal （institutional）, socio-economic approaches were used during the research of transaction costs function. The authors used the complex of ideas and different methods of sociological and economic analysis that allowed deepening the importance of institutional state regulation of business activity in housing construction area. The classification of transaction costs creation was worked out; this model unlike well-known models considers the most important parts of transaction costs which really exist in business activity of construction companies nowadays; implementation of the model allows calculating and predicting this kind of costs in business. Recently Russian government returns to the questions about efficiency of production （increase of labor productivity, efficiency and profitability of production）, therefore attention to the reduction of transaction costs is going to increase profits and efficiency.     

An experimental study of the impact of competition for Other People’s Money: the portfolio manager market

In this paper we experimentally investigate the impact that competing for funds has on the risk-taking behavior of laboratory portfolio managers compensated through an option-like scheme according to which the manager receives (most of) the compensation only for returns in excess of pre-specified strike price. We find that such a competitive environment and contractual arrangement lead, both in theory and in the lab, to inefficient risk taking behavior on the part of portfolio managers. We then study various policy interventions, obtained by manipulating various aspects of the competitive environment and the contractual arrangement, e.g., the Transparency of the contracts offered, the Risk Sharing component in the contract linking portfolio managers to investors, etc. While all these interventions would induce portfolio managers, at equilibrium, to efficiently invest funds in safe assets, we find that, in the lab, Transparency is most effective in incentivising managers to do so. Finally, we document a behavioral “Other People’s Money” effect in the lab, where portfolio managers tend to invest the funds of their investors in a more risky manner than their Own Money, even when it is not in either the investors’ or the managers’ interest to do so.     

A new dualistic approach to brand passion: Harmonious and obsessive

Brand passion is increasingly seen as the ultimate emotional connection between the consumer and a brand. Limited previous research relied exclusively on Sternberg's triangular interpersonal theory in developing the brand passion concept. This research paper integrates consumer brand identity theory, refines the definition of brand passion, and proposes a dualistic approach to brand passion which distinguishes between two different types of brand passion: harmonious and obsessive.     

The efficiency of the Environmental Management Charge in the Cairns management area of the Great Barrier Reef Marine Park*

Using data from a survey of more than 1000 domestic visitors to the Northern section of the Great Barrier Reef (GBR) – predominantly those travelling on live‐aboard dive boats – this research investigates the (tax) efficiency of the Environmental Management Charge (EMC). The travel cost method (with a zero truncated negative binomial specification) is used to estimate the price elasticity of demand, and those estimates are used to estimate the deadweight losses, the losses in visitor numbers that could be ‘blamed’ on the EMC and the associated taxation revenues for different types of trips. The welfare loss for each dollar of revenue raised from the EMC was estimated at less than one per cent for each type of trip considered. The analysis therefore suggests that, for these types of trips in this part of the reef at least, the EMC is a very efficient tax – particularly when compared with other taxes. This has important implications beyond the GBR, particularly in countries who struggle to find sufficient funds to properly manage world heritage areas: taxes such as these may be a relatively efficient and equitable means of collecting such revenues.     

The take-off of an interactive innovation: Evidence from China

An interactive innovation can be defined as an end-user application which is subject to network effects at both the demand and supply sides. As a result of network effects, the diffusion of such an innovation is predicted to follow a take-off curve coinciding with the advent of a critical mass of adopters. The current literature on innovation diffusion, mainly focusing on the demand-side dynamics, such as information cascades and herding behaviors among potential adopters, is not sufficient to explain the take-off (or the failure) of interactive innovations. In this paper, we present and examine a case study of the take-off of an interactive innovation, namely the caller-ring-back-tone (CRBT) and mobile music - mobile value-added services (MVAS) - in China. We find that supply-side dynamics, such as choices of platform strategies, helped drive the take-off of this innovation within China's institutional boundaries. The paper makes a contribution in two ways: first, it presents an ‘inside-out’ view of a unique case of take-off phenomenon; and, second it provides an integrated view combining factors from both the demand and supply sides to explain the take-off phenomenon, which is rare in empirical studies.     

Identification-commitment inventory (ICI model): confirmatory factor analysis and construct validity

The aim of this study is to confirm the factorial structure of the Identification-Commitment Inventory (ICI) developed within the frame of the Human System Audit (HSA) (Quijano et al. in Revist Psicol Soc Apl 10(2):27–61, 2000; Pap Psicól Revist Col Of Psicó 29:92–106, 2008). Commitment and identification are understood by the HSA at an individual level as part of the quality of human processes and resources in an organization; and therefore as antecedents of important organizational outcomes, such as personnel turnover intentions, organizational citizenship behavior, etc. (Meyer et al. in J Org Behav 27:665–683, 2006). The theoretical integrative model which underlies ICI Quijano et al. (2000) was tested in a sample (N = 625) of workers in a Spanish public hospital. Confirmatory factor analysis through structural equation modeling was performed. Elliptical least square solution was chosen as estimator procedure on account of non-normal distribution of the variables. The results confirm the goodness of fit of an integrative model, which underlies the relation between Commitment and Identification, although each one is operatively different.     

Analytical pricing of discretely monitored Asian-style options: Theory and application to commodity markets

We compute an analytical expression for the moment generating function of the joint random vector consisting of a spot price and its discretely monitored average for a large class of square-root price dynamics. This result, combined with the Fourier transform pricing method proposed by Carr and Madan [Carr, P., Madan D., 1999. Option valuation using the fast Fourier transform. Journal of Computational Finance 2(4), Summer, 61–73] allows us to derive a closed-form formula for the fair value of discretely monitored Asian-style options. Our analysis encompasses the case of commodity price dynamics displaying mean reversion and jointly fitting a quoted futures curve and the seasonal structure of spot price volatility. Four tests are conducted to assess the relative performance of the pricing procedure stemming from our formulae. Empirical results based on natural gas data from NYMEX and corn data from CBOT show a remarkable improvement over the main alternative techniques developed for pricing Asian-style options within the market standard framework of geometric Brownian motion.     

Comparative Analysis of Text Data in Successful Face-to-Face and Electronic Negotiations

Various combination of Natural Language Processing and Machine Learning methods offer ample opportunities wherever texts are an important element of an application or a research area. Such methods discover patterns and regularities in the data, seek generalization and in effect learn new knowledge. We have employed such methods in learning from a large amount of textual data. Our application is electronic negotiations. The genre of texts found in electronic negotiations may seem limited. It is an important research question whether our methods and findings apply equally well to texts that come from face-to-face negotiations. In order to confirm such more general applicability, we have analyzed comparable collections of texts from electronic and face-to-face negotiations. We present our findings on the extent of similarity between these two related but distinct genres. In this study we have analyzed similarities in the text data of electronic and face-to-face negotiations. The results show that – in certain conditions – vocabulary richness, language complexity and text predictability are similar.This is an expanded version of a paper published in the Proceedings of FINEXIN 2005 (Workshop on the Analysis of Formal and Informal Information Exchange during Negotiations), 31–42, Ottawa, Canada, May 2005.     

Overtourism and degrowth: a social movements perspective

Abstract

Overtourism is a contemporary phenomenon, rapidly evolving and underlined by what is evidently excessive visitation to tourist destinations. This is obvious in the seemingly uncontrolled and unplanned occurrence of urban overtourism in popular destinations and arguably a consequence of unregulated capital accumulation and growth strategies heavily associated with selling cities as tourism commodities. The vested interests of social movements has converged into growing protests against overtourism and associated degrowth campaigns have emerged out of this activism that calls for alternative governance and management measures that eschew touristic monoculture and simplistic economic growth-oriented models. Accordingly, we explore the evolution of the tourism degrowth discourse among social movement activists in Barcelona, and in particular, where this is related to claims associated with overtourism and the extent to which this might be influencing a paradigm shift from ‘tourism growth’ to ‘tourism degrowth’. Methodologically, we draw from an overarching framework that leverages long-term ethnographic research in Barcelona. Here, we employ in-depth semi-structured interviews, participant observations, informal conversations and retrospective evaluation of field diary entries.
