Individual and Group Dynamics in Purchasing Activity

As a major part of the daily operation in an enterprise, purchasing frequency is of constant change. Recent approaches on the human dynamics can provide some new insights into the economic behaviors of companies in the supply chain. This paper captures the attributes of creation times of purchase orders to an individual vendor, as well as to all vendors, and further investigates whether they have some kind of dynamics by applying logarithmic binning to the construction of distribution plot. It's found that the former displays a power-law distribution with approximate exponent 2.0, while the latter is fitted by a mixture distribution with both power-law and exponential characteristics. Obviously, two distinctive characteristics are presented for the interval time distribution from the perspective of individual dynamics and group dynamics. Actually, this mixing feature can be attributed to the fitting deviations as they are negligible for individual dynamics, but those of different vendors are cumulated and then lead to an exponential factor for group dynamics. To better describe the mechanism generating the heterogeneity of purchase order assignment process from the objective company to all its vendors, a model driven by product life cycle is introduced, and then the analytical distribution and the simulation result are obtained, which are in good line with the empirical data

Managing the market place: the consortium approach

The funding context of higher education is examined, together with some of the constraints and imperatives to which it gives rise. The history, constitution and operation of the Southern Universities Purchasing Consortium's Libraries Project Group are discussed. The paper closes with a discussion of possible future roles for purchasing consortia

The Instrumental Genesis of Collective Activity. The Case of an ERP Implementation in a Large Electricity Producer

Collective activity should be a focal subject to study organizational dynamics, particularly in relation with the implementation of management systems such as ERPs. Collective activity is analyzed here as an ongoing dialogical construction by actors. It is always mediated by signs and particularly by instruments. To design and adapt collective activity, a reflexive dialogical exchange between actors, a “collective activity about collective activity”, mediated by instruments, is necessary: we call it “the instrumental genesis of collective activity”. We analyze the case of an ERP implementation at EDF, a large electricity company, in the purchase and procurement area of the production division. The design and implementation of the new system was not clearly viewed as the instrumental genesis of collective activity. Difficulties appeared particularly for cross-functional cooperation and for the construction of new professional profiles of competence. In the light of this case, we suggest that key conditions for the intelligibility and the actionability of collective activity are the establishment of communities and the hybridization of professional competences.Collective Activity; Collective Sensemaking; Community; Dialogical; ERP; Instruments; Instrumental Genesis of Activity; Interpretation; Sign

Library purchasing consortia: achieving value for money and shaping the emerging electronic marketplace

Drawing on a current study, funded by the British Library Research and Innovation Centre, the context of higher education libraries is discussed, including funding and costs and recent major official reports on education and libraries. Future trends and imperatives are outlined. Models of library purchasing consortia are presented. The operation of the Southern Universities Purchasing Consortium’s Libraries Project Group is examined in detail. The lessons and benefits of consortium membership are discussed. The future influence of purchasing consortia, particularly on the regional library and on electronic publishing are examined

Leadership of healthcare commissioning networks in England : a mixed-methods study on clinical commissioning groups

Objective: To explore the relational challenges for general practitioner (GP) leaders setting up new network-centric commissioning organisations in the recent health policy reform in England, we use innovation network theory to identify key network leadership practices that facilitate healthcare innovation. Design: Mixed-method, multisite and case study research. Setting: Six clinical commissioning groups and local clusters in the East of England area, covering in total 208 GPs and 1 662 000 population. Methods: Semistructured interviews with 56 lead GPs, practice managers and staff from the local health authorities (primary care trusts, PCT) as well as various healthcare professionals; 21 observations of clinical commissioning group (CCG) board and executive meetings; electronic survey of 58 CCG board members (these included GPs, practice managers, PCT employees, nurses and patient representatives) and subsequent social network analysis. Main outcome measures: Collaborative relationships between CCG board members and stakeholders from their healthcare network; clarifying the role of GPs as network leaders; strengths and areas for development of CCGs. Results: Drawing upon innovation network theory provides unique insights of the CCG leaders’ activities in establishing best practices and introducing new clinical pathways. In this context we identified three network leadership roles: managing knowledge flows, managing network coherence and managing network stability. Knowledge sharing and effective collaboration among GPs enable network stability and the alignment of CCG objectives with those of the wider health system (network coherence). Even though activities varied between commissioning groups, collaborative initiatives were common. However, there was significant variation among CCGs around the level of engagement with providers, patients and local authorities. Locality (sub) groups played an important role because they linked commissioning decisions with patient needs and brought the leaders closer to frontline stakeholders. Conclusions: With the new commissioning arrangements, the leaders should seek to move away from dyadic and transactional relationships to a network structure, thereby emphasising on the emerging relational focus of their roles. Managing knowledge mobility, healthcare network coherence and network stability are the three clinical leadership processes that CCG leaders need to consider in coordinating their network and facilitating the development of good clinical commissioning decisions, best practices and innovative services. To successfully manage these processes, CCG leaders need to leverage the relational capabilities of their network as well as their clinical expertise to establish appropriate collaborations that may improve the healthcare services in England. Lack of local GP engagement adds uncertainty to the system and increases the risk of commissioning decisions being irrelevant and inefficient from patient and provider perspectives

THE CONSUMER’S SATISFACTION – AS A FACTOR FOR SUCCESS IN TRAVEL TRADE COMPANIES

The consumers are subjects that purchase goods and services in order to satisfy their needs. The behavior of the consumers is a process in which they decide whether, what, when, where, and how to purchase goods and services. The marketing is therefore, primarily interested in the behavior of the subject as a consumer. In the modern circumstances, it’s normal to suppose that the marketing is permanently following the needs of the consumers as a basic supposition for the development of the suitable strategy leading to the customer’s satisfaction. But it should be taken into consideration that the needs are a social category changing all the time and are never satisfied. With the setting of a suitable strategy based on qualitative information, the marketers contribute to the development of a loyal consumer’s category that will lead to the realisation of a general strategy, to the survival and the development of a travel trade company.Needs; Motives; Satisfaction; Consumer; Travel trade companies.

A Synthesis of the Literature on the Relationship Between Food Access and Overweight and Obesity in African American Adolescents

Food access shapes a community’s nutritional environment and impacts the health and physical well-being of its residents. When a community does not have adequate access to outlets that offer healthy options, it is difficult to maintain a healthy diet. As a result, we often see higher rates of chronic disease, overweight and obesity among some populations. African American communities may be disproportionately affected by overweight and obesity because of limited food access. This literature review examines the public health significance of food access and how the presence of full service grocery stores impacts eating habits and overweight and obesity among African American adolescents. The results are primarily cross-sectional studies organized and presented in three sections: (1) food environment, (2) eating habits, and (3) policy implications. The findings in this literature review suggest that the problem of overweight and obesity in African American adolescents is indeed a multi-faceted issue. While there does appear to be a correlation between access to full service supermarkets and eating behaviors, overweight and obesity, there are other factors to consider. It is unclear if the presence of more full-service supermarkets alone is enough to significantly impact a reduction of overweight and obesity among African-American youth. While quantitative studies provide important baseline data, researchers should consider developing qualitative studies that may offer additional insight into individual, family and environmental factors that vary geographically
