This article offers a theoretical analysis of evolutionary processes in WBSS strategies. For that purpose, we propose a research model that shows strategy patterns. Based upon the model, we identified several types of strategies. In our research model, WBSS are classified into four types: (1) general-direct-sales (GDS); (2) general-intermediary-sales (GIS); (3) specialized-direct-sales (SDS); and (4) specializedintermediary- sales (SIS). On the basis of these four categories of WBSS, we analyze the characteristics of WBSS and suggest five evolution strategies for WBSS, which have implications for both theory and practice. Amazon.com’s strategic movements, such as product line expansion through alliance and acquisition, provide an exemplary case of the evolution of WBSS strategy. We expect that this research will serve as a guide for Internet businesses and as a catalyst for new research agendas relevant to Web-based shopping and electronic commerce.

The world is witnessing a continuous expansion of electronic commerce into the global digital economy. As an enabler of new businesses, Web-based shopping systems (WBSS) are at the heart of the major issues surrounding electronic commerce growth. Their wide use has profoundly altered the ways in which businesses and customers, and businesses and businesses interact on the basis of digital transactions. Despite the importance of WBSS, the theoretical study of their strategies has been sparse. This article offers a theoretical analysis of evolutionary processes in WBSS strategies. For that purpose, we propose a classification model of WBSS. Based upon the model, WBSS are classified into four types: (1) general-direct-sales (GDS); (2) general-intermediary-sales (GIS); (3) specialized-direct-sales (SDS); and (4) specialized-intermediary-sales (SIS).

A major puzzle in international relations is why states privilege negative over positive information. States tend to inflate threats, exhibit loss aversion, and learn more from failures than from successes. Rationalist accounts fail to explain this phenomenon, because systematically overweighting bad over good may in fact undermine state interests. New research in psychology, however, offers an explanation. The “negativity bias” has emerged as a fundamental principle of the human mind, in which people's response to positive and negative information is asymmetric. Negative factors have greater effects than positive factors across a wide range of psychological phenomena, including cognition, motivation, emotion, information processing, decision-making, learning, and memory. Put simply, bad is stronger than good. Scholars have long pointed to the role of positive biases, such as overconfidence, in causing war, but negative biases are actually more pervasive and may represent a core explanation for patterns of conflict. Positive and negative dispositions apply in different contexts. People privilege negative information about the external environment and other actors, but positive information about themselves. The coexistence of biases can increase the potential for conflict. Decisionmakers simultaneously exaggerate the severity of threats and exhibit overconfidence about their capacity to deal with them. Overall, the negativity bias is a potent force in human judgment and decisionmaking, with important implications for international relations theory and practice.

An important component of successful economic activity of industrial enterprises is the optimal sales model combined with e-commerce opportunities. The article analyzed two construction materials manufacturing enterprises categories: those using exclusively a sales network for the promotion of their products, and those developing a direct sales system to the final consumer via electronic commerce. These are basically two different logistical approaches to the process of selling their own products. The efficiency of using e-commerce logistics means is determined by the correlation of sales expenses index with an indicator of enterprises' net income. It was proved sales expenses' indicator affects the dynamics of the net income indicator positively only for the enterprises using e-commerce logistics as a means of setting up a direct sales channel for their products. The article provides recommendations for creating an optimal logistics e-commerce system for construction materials manufacturing enterprises.

The concept of ‘agency’ is regularly put forward as an analytic tool to help understand, evaluate and act upon places around the world, through social development policies and programmes ostensibly designed to support or increase children’s agency. This article reflects on empirical research into children’s agency spanning a range of international contexts over two decades and offers new insights through critical engagement with a growing body of work on the ‘localisation’ of social development and humanitarian responses in international settings. It suggests that the largely normative ways in which the concept of agency is invoked as an analytic tool for understanding human experience universally effectively renders children’s agency invisible to us. This is because it is more a description of a particular discourse than something which actually helps us to understand and make visible children’s socio-culturally grounded ‘agentic practice’ from place to place. This article argues for new directions in research and practice to localise agency that are critical to the central commitments of interpretive social science. These new directions include (a) a new research agenda which can go beyond children’s ‘own perspectives’ to the discovery, description and analysis of agency in socio-cultural terms, to ensure it can function as an analytic tool for learning about socio-cultural phenomena which help animate local concepts of agency; and (b) the development of agency-related policies and programmes that are grounded in such locally situated concepts of agency developed through understanding local socio-cultural systems rather than externally derived socio-cultural assumptions about childhood and children’s agency.

In recent years medical education has developed dramatically, but lecturers often cite the existence of a gap between theoretical and practical knowledge. In the first decade of the present century, new research methodology named “design-based research (DBR)” was developed, which most experts and journals refer to as a fundamental way to make changes in the quality and applicability of studies and educational research as well as to enhance and improve the practice of instruction. The aim of the present study was introducing design-based research and its concepts, features, applications, and challenges. A narrative review was conducted in 2018. For this purpose, authorized English academic database including Web of Science, Science Direct, Google Scholar, international database and library in medical research filed with keywords including “design-based research, definition of DBR, DBR applications, medical education, and DBR challenges” without date limitation until 2018.11.21 were screened. Overall, 68 articles were selected and after careful reading, 21 article with related subjects were selected for material extraction. The conclusion was made that DBR that combines empirical research with design-based theories could be considered as an effective method for understanding quality, time and the cause of the phenomenon of educational innovation in practice. Usually DBR is formed by initial evaluation of a problem that occurs in a particular context, and this assessment continues throughout design and implementation. One of the characteristics of DBR is the guiding team, which includes researchers, professionals, designers, managers, teachers, trainers and others whose expertise and knowledge may in some way help. The application of DBR in web-based training programs is quite evident. The probability of non-returns in short-term projects is one of the main challenges of DBR. Medical education has developed dramatically in recent years, but it has made little progress in promoting innovative research methodologies. DBR can be used as a bridge between theories and practice and provide the basis for close communication between researchers, designers, and participants. By applying sophisticated methods and multiple sources of information, the success rate of an intervention in a particular environment is assessed, which ultimately leads to improved theories.

Offline Channels

The Internet is becoming increasingly important as a sales channel. Thus, most large retail firms have adopted a multi-channel strategy that includes both web-based channels and pre-existing offline channels. In this paper, we consider joint pricing and inventory/production decision problems for members in a monopoly two-stage dual-channel retailer supply chain. For a dual-channel retailer, pricing in one channel will affect the demand in the other channel. This subsequently affects the retailer's replenishment (ordering) decisions, which have an impact on the producer's inventory/production plans and wholesale price decisions. It is clear then that pricing decisions and inventory/production decisions are interacting in each member of the supply chain and among the members in the chain as well. In this paper, we analyze joint pricing and inventory/production problems under three scenarios by incorporating intra-product line price interaction in the EOQ model. We show that a unique equilibrium exists under certain realistic conditions. We also provide numerical results that offer insights for pricing strategies for the dual-channel retailer supply chain and for product design for different channels.

AbstractThe World Wide Web has had a notable impact on a variety of epistemically relevant activities, many of which lie at the heart of the discipline of knowledge engineering. Systems like Wikipedia, for example, have altered our views regarding the acquisition of knowledge, while citizen science systems such as Galaxy Zoo have arguably transformed our approach to knowledge discovery. Other Web-based systems have highlighted the ways in which the human social environment can be used to support the development of intelligent systems, either by contributing to the provision of epistemic resources or by helping to shape the profile of machine learning. In the present paper, such systems are referred to asknowledge machines. In addition to providing an overview of the knowledge machine concept, the present paper reviews a number of issues that are associated with the scientific and philosophical study of knowledge machines. These include the potential impact of knowledge machines for the theory and practice of knowledge engineering, the role of social participation in the realization of knowledge-based processes, and the role of standardized, semantically enriched data formats in supporting thead hocassembly of special-purpose knowledge systems and knowledge processing pipelines.

Theory Of Structuration

This chapter presents a perspective on web technologies acquisition, utilization, organization change and transformation grounded in Gidden’s theory of structuration, i.e., a contextualist analysis. A contextualist analysis is processually based, emergent, situational, and holistic, marrying both theory and practice. This chapter’s paradigm affords a substantive analytical tool to the practitioner for understanding and managing not only web-based IT acquisition, utilization and organization change, but all IT-based recursive, organization changes and transformations. Organization change associated with IT acquisition and utilization is posited as concomitantly necessary. Organization change is recursive, dynamic, multilevel, and nonlinear, i.e., an “enacted” environment. Ever present organization opposing values are treated dialectically, i.e. as paradox, operating simultaneously. The nature of the resolution of such paradox enabled/inhibits reframing, i.e., organization transformation and change. The paradigm presented defines an organization change continuum, delineating four organization responses to contradiction and paradox. The chapter explicates organization culture and organization learning as systemic, multiplicative metaforce underpinnings of organization change and sociocognitively-based, recursive, structurational processual dynamics. The chapter discusses use of the IT acquisition and utilization paradigm for organization diagnosis as well as customization of organization change interventions. The chapter suggests further typologically-based research venues.
