Abstract

In the vision of pervasive computing, numerous heterogeneous devices, various information services, and users performing daily activities are physically co‐located in a environment. How can we coordinate the services and devices to assist a particular user in receiving a particular service so as to maximize the user’s satisfaction? To solve this human‐centered coordination issue, we propose an agent‐based service coordination framework for pervasive computing. It is called location‐aware middle agent framework. The middle agent takes account of the user location in cognitive way (based on location‐ontology), and determines best‐matched services for the user. Based on this coordination framework, we have developed a multi‐agent architecture for pervasive computing, called CONSORTS (Coordination System of Real‐world Transaction Services). In this paper, we first outline some requirements of the human‐centered service coordination in pervasive computing. Secondly, we describe location‐aware middle agent framework to fill the requirements. Lastly, we outline CONSORTS, an prototype of location‐aware middle agent framework, and two applications of CONSORTS, location‐aware information assistance services in a museum and wireless‐LAN based location systems on FIPA agent Networks.

Abstract

I study the economic implications of the world oil market dominated by OPEC and non-OPEC major oil producing countries using a general equilibrium model of trilateral trade with oil duopoly. There are three countries and three goods, x, y, and oil (z). Home (H) is endowed with good x . Foreign (F) is endowed with good y and also produces oil (z). Middle (M) is an oil producing country and supplies oil only. I consider two types of oil market structure; (1) Cournot duopoly and (2) perfect competition. I find that Foreign is actually worse off under Cournot duopoly despite being a duopolist for wide range of parameter values that reflect real world situations. This is mainly due to reduced consumption of oil and reduced value of good y endowment under duopoly when Foreign is a net oil exporter or oil autarky, and is also due to worsening terms-of-trade effect under duopoly when Foreign is a net oil importer. Welfare reversal with higher welfare of Foreign under oil duopoly occurs only under highly unrealistic parameter values, and hence the main results of the study remain robust.

Abstract

Hydrological and climatological modeling is increasingly being used with the intent of supporting community-based climate change adaptation (CCA) and disaster risk reduction (DRR) initiatives in the Hindu Kush-Himalaya (HKH), as well as filling critical data gaps in a region that contributes significantly to the water resources and ecosystem diversity of Asia. As the case studies presented in the previous chapters illustrate, the utility of modeling in informing and supporting CCA and DRR initiatives depends on a number of criteria, including:•appropriate model selection;•ability to interpret models to local contexts; and•community engagement that incorporates and addresses underlying vulnerabilities within the community.

There are significant challenges to meeting all three of these criteria. However, when these criteria are met, we find:•There is a clear role for modeling to support CCA. The climate is changing now and will continue to do so for several centuries, even if carbon emissions were to stabilize tomorrow. Models, and other scenario development tools, provide our best insight into what the future climate might be and resulting impacts on dynamic social, environmental, political, and economic systems.•There is a clear role for local CCA. The impacts of climate change will be felt mostly at local levels, necessitating community adaptation responses. At the same time, most of the HKH communities and countries engaged in CCA initiatives have pressing, immediate development and livelihood needs. Making current development and livelihood initiatives incorporate climate adaptation considerations is the best way to ensure that the choices made today can set us on paths of increasing resilience, rather than almost inevitable disaster, for the future.•To achieve the best of both modeling and CCA requires thoughtful and patient application of modeling, tailored to local needs, conditions, and politics, with communities engaged around all stages of generating, interpreting, and applying the results. This requires a rare combination of technical skill, cultural sensitivity, political awareness, and above all, the time to continually engage with and build relationships within the community in order to foster resilient change.

Abstract

When an international firm enters an overseas market, international distribution channel structure is very important. Distribution channel structures decisions are made by examining the company’s degree of commitment and risk, and are not only difficult to change but initial wrong decisions may lead to poor results. Therefore, channel satisfaction is higher when channel structure is appropriate for the foreign market. Examines factors leading to a firm’s satisfaction with international marketing channels. Builds on existing studies about consumer satisfaction and distribution channel structures. As theoretical background, a transaction cost factor and the discrepancy model is used to examine the determinants of satisfaction. Findings from a survey of Korean electronic export corporations show that a firm’s relative performance and control variables provide significant explanations for channel satisfaction, and the channel structure variable is supported by null hypothesis.

Abstract

Purpose

The main objective of this study is to consider how to benefit efficiently from the significant potential of humanitarian operations by individuals. For this purpose, this study aims to assess failure factors in humanitarian supply chain operations after the Kermanshah earthquake considering the role of all parties, focusing on individuals who did not wish to work with formal organisations on the whole. In the aftermath of the Kermanshah earthquake, which occurred on 12 November 2017, improvised groups of Iranian civilians from all over the country played an important role in humanitarian supply chain operations as individuals. Although most of these groups sincerely intended to help the affected society, victims could not benefit properly from these significant potential humanitarian actions. On the contrary, these potential actions caused some issues during humanitarian operations, such as blocking roads, inappropriate last-mile distribution, wasting resources and so on.

Design/methodology/approach

This research study considers mixed methods, including an on-site survey, semi-structured interviewing and a questionnaire designed for statistical analyses. The analysis included 140 responses to the questionnaire, semi-structured interviews with 32 affected families, interviews with 5 emergency managers from the Housing Foundation of the Islamic Republic of Iran and on-site survey reports.

Findings

This study presents a framework for humanitarian supply chain management to deal with future disasters in the same area or areas with similar characteristics to the case study. In general, the results of this study demonstrate that the nature of humanitarian supply chain operations makes it impossible to consider that these operations are free of challenges. However, several influential factors, such as training humanitarian actors and integrated management, might considerably increase the efficiency of humanitarian operations by individuals.

Originality/value

This study highlights the influential factors of inappropriate humanitarian operations by individuals, derived from an analysis of the Kermanshah case and literature review. The authors suggest a framework to benefit from the significant potential of individuals with wide-ranging experiences and proficiency, for future cases similar to the case study.

Abstract

Purpose

The purpose of this research is to segment Pakistani consumers based on their insights and preference towards mango quality and safety attributes and to demographically characterise each segment so that effective value chain (VC) development strategies may be developed.

Design/methodology/approach

Factor and cluster analysis were applied to data collected from 400 mango buyers randomly selected from seven different cities in Pakistan.

Findings

This empirical study identified four distinct segments of mango consumers in Pakistan. The diversity of consumers' perception was mainly based on four factors: food safety, price and marketing, physical quality and shelf life. Based on their demographic characteristics and preferences for product attributes, the identified consumer segments can be classified as “traditional consumers,” “safety-conscious consumers,” price and market-sensitive consumers,” quality-sensitive consumers” and “perfect consumers.” This knowledge is useful to develop mango VCs that target specific consumer segments based on their chain level abilities and aspirations.

Research limitations/implications

This study offers actors of mango VCs an enhanced understanding of consumer segments based on their perceived preferences towards the quality and safety attributes of mangoes, which would help VC actors design and develop business strategies that deliver value specific to each consumer segments. Findings of this study could also be useful to policy makers to design extension strategies that promote food safety and quality standards in mango VCs. Moreover, this study presents yet another case of consumer segmentation study for VC development in developing countries, adding a stepping stone towards a general VC theory development.

Originality/value

The findings stimulate the momentum of the growing literature, particularly in the developing countries on consumer insights and behaviour toward fruit quality and safety attributes of mangoes.

Abstract

Purpose

This paper aims to assist managers and food supply chain practitioners in efficiently implementing lean and green (LG) practices for sustainability. Examining barriers to LG practices, as well as prioritizing mitigation strategies in the food supply chain, are all part of this work.

Design/methodology/approach

Using a combination of literature review and expert team inputs, this paper investigated the LG barriers and their solutions under PESTEL (Political, Economic, Social, Technological, Environmental and Legal) framework. To prioritize them, this work used the fuzzy best worst method (fuzzy BWM) with the fuzzy technique for order preference by similarity to ideal solution (FTOPSIS).

Findings

From the fuzzy BWM, the economic barriers were identified as the most significant. From the FTOPSIS approach, top management expertise and commitment to adopting LG practices were identified as the best solution for overcoming the barriers.

Practical implications

This paper discusses the barriers and solutions for successfully implementing LG techniques from the real-time food supply chain. The practitioners and food chain managers welcomed the methodology for its use in prioritizing the barriers to LG practices. Conclusions drawn from this work were found to be realistic.

Originality/value

The original contribution of this study is to present the model framework for barriers and solutions of LG practices in the dairy supply chain using the hybrid MCDM technique.

Abstract

Purpose

China's rise as a major player in world affairs has contributed significantly to the global interest in the study of Chinese language, society, and culture. Its emerging importance has also increased the need for China‐related library materials and information provision to China scholars and the general public in recent years. This paper seeks to trace the historical transformation and renewed interest in China studies and the growing demand placed on Asian or East Asian libraries that support China studies in the USA.

Design/methodology/approach

The paper is a general review of the issues and challenges facing libraries in the West, which serve Chinese scholars, with the increasing demand for China‐related library materials and information resources, as well as for delivery of such information resources.

Findings

The paper identifies the issues and challenges facing libraries in the West that serve China scholars. The importance of collection building in China studies, the role of Chinese studies librarians, professional support for East Asian studies librarians in North America, and the changing outlook of academic libraries is highlighted.

Practical implications

In a world that is increasingly more global, Asian or East Asian libraries must gain better understanding if the issues and best practices to effectively provide information service through collaboration and resource sharing with partners in Asia to achieve true global collections.

Originality/value

The paper presents possible measures that can be undertaken to bridge the difference between the East and West. Specifically, the paper addresses concerns libraries outside China encounter and proposes suggestions regarding resource sharing, balancing a Chinese collection in a networked environment, financial challenges, continuing education, and bibliographic control.

Abstract

Purpose

To provide an overview of the growing international movement of librarians, faculty members, and researchers who are working together to develop new methods of scholarly communication, including Open Access (OA) journals, digital e‐print archives, and institutional repositories, and to press for public access to federally funded research.

Design/methodology/approach

Key elements which have created pressures for change in the scholarly communication system are reviewed: the development and expansion of the Internet and networked technologies, and rapidly increasing journal costs due to consolidation, pricing structures and title aggregating in the commercial journal publishing industry. Effects of these pressures on libraries, citing Bowdoin College as an illustrative case, and examples of OA and affordably priced journal publishing models and OA principles and infrastructure are presented.

Findings

The OA movement has gained momentum and appears to be meeting with some success, with worldwide efforts to make federally funded research available to taxpayers and the largest science, technology and medicine journal publishers revisiting pricing structures. It is predicted that commercial journals, OA journals and digital repositories will continue to co‐exist as information resources for the scholarly community for the foreseeable future.

Research limitations/implications

This is not an exhaustive history, but rather a review of movement highlights, written by a steering committee member of SPARC, a major scholarly communication movement stakeholder.

Originality/value

A useful overview for librarians and researchers unfamiliar with the movement who wish to educate local faculty members about the implications for their publishing and professional activities, as well as for commercial publishers and scholarly presses interested in learning more about the movement.

Abstract

Purpose

The purpose of this paper is to verify whether, besides the traditional organisational models mainly implemented by wine-making cooperatives, more modern and hybrid organisational forms can be profitably applied within an increasingly competitive wine market.

Design/methodology/approach

The study outlined in this paper deployed a mixed method. Specifically, an archived analysis, a survey and a descriptive case study (including visits, interviews and documentary analysis) were the methodological techniques used in this study, which were “in series but integrated” between themselves. In this paper, the landscape of Sicilian wine cooperatives is described by collating and processing different types of statistical sources, which have been integrated by direct surveys undertaken in 2017. Thereafter, the study focussed on a wine cooperative with a specific business model and a strategic edge by analysing its strategic choices and main structural and governance characteristics. Within this case study, a financial ratio analysis, which was based on 2011-2017 financial statements, was conducted to analyse the profitability, financial balance, capital structure and debt relationships of the wine cooperative.

Findings

The Sicilian wine cooperative system is still predominantly characterised by partial and vertical integration, implemented by cooperatives which elect to sell mainly bulk wine to wine merchants. In such a context, there is scope for other degrees of integration and strategic inter-firm alliances; the latter includes “vertical quasi-integration”. The study demonstrated how the wine cooperative under investigation is overcoming the structural problems of the regional wine sector and why it is retaining such a strategic alliance with one of the most important Italian wine conglomerates. Indeed, it has acquired greater strength and reliability since its collaboration with the aforementioned wine company. Thus, total revenue and the company’s market share of packaged wine have increased. However, there are still margins for improving sales’ profitability.

Research limitations/implications

This study has territorial limitations but Sicilian wine cooperatives generally play an important role in the regional, Italian and European wine industries. As such, this research should be considered as an exploratory study, deserving further investigation into different strategic choices within the wine cooperative system by performing cross-case comparisons. Results may also be useful in orienting cooperative strategies in Sicily (or further afield) to small-to-medium wine cooperatives, often lacking specific abilities relating to the distribution, marketing and selling of their wine. Public agricultural policies may also be enlightened by these research pathways.

Originality/value

The authors contend that their study provides hitherto missing information relating to inter-firm strategic alliances, which wine cooperatives might implement to enhance their competitiveness and survive in the long-run.
