Supply chain management for small business--how to avoid being part of the food chain

A supply chain is a series of customer and supplier relationships that extend throughout and beyond the company. It is an interwoven set of links that together form a chain supplying our customers in a seamless and integrated fashion delivering a high level of customer satisfaction. Supply chain management (SCM) integrates all activities so they are focused on customer satisfaction (both internally and externally). One of the things this article will attempt to accomplish is to provide a clear understanding of SCM's positive impact on customer service as well as on improving profitability, cash flow, product cycle times, and communication. Whether we go forward in the supply chain to the final end-user or backward in the supply chain to our supplier's suppliers, SCM will significantly improve our ability to serve our customers.     

Noncentral bimatrix variate generalised beta distributions

In this paper, we determine the density functions of nonsymmetrised doubly noncentral matrix variate beta type I and II distributions. The nonsymmetrised density functions of doubly noncentral and noncentral bimatrix variate generalised beta type I and II distributions are also obtained.     

Multivariate contemporaneous-threshold autoregressive models

This paper proposes a contemporaneous-threshold multivariate smooth transition autoregressive (C-MSTAR) model in which the regime weights depend on the ex-ante probabilities that latent regime-specific variables exceed certain threshold values. A key feature of the model is that the transition function depends on all the parameters of the model as well as on the data. Since the mixing weights are also a function of the regime-specific noise covariance matrix, the model can account for contemporaneous regime-specific co-movements of the variables. The stability and distributional properties of the proposed model are discussed, as well as issues of estimation, testing and forecasting. The practical usefulness of the C-MSTAR model is illustrated by examining the relationship between US stock prices and interest rates.     

The co-occurrence of self-observed norm-conforming behavior,reduction of zero observations and remaining measurement quality

Norm-violating behavior is characterized by clear social norms which prescribe the non-occurrence of that behavior. From the theoretical framework of Allport it is derived that specifically norm-conformation is consistent, while violating norms is expected to be inconsistent and more circumstantial. This is in contrast to test-theoretic approaches of delinquent behavior that assume that various norm-violating responses form a consistent answer pattern that is scalable and reliable. In this study we study the inter-correlations, scalability and reliability of norm-violating responses and their relation with the reduction of zero observations. In concordance with Allport’s view it is expected that different norm-violating self-report items have limited interrelatedness and are limited in scalability and reliability in the norm-violating sub-population. The NLSY98 self-report data show that a large majority of respondents (69 %) conform systematically to all ten different norms, while only nine percent admits more than two different violations. The results show that in subsamples of norm-violating respondents, the correlations between items become closer to zero, dependent on the amount of zero reduction. Furthermore, both Loevinger’s H coefficient of scalability and scale reliability become unsatisfactorily low, when 35 % or more strict norm-conforming subjects are removed.     

Perceived compensation discrimination against physically disabled people in Andalusia

This study proposes and tests a model that explains the job dissatisfaction of the physically disabled as a result of their general perception that they are treated inequitably by their employer, and their specific perception that they have experienced discrimination in compensation. These three variables have not previously been studied in combination. Using the theoretical framework of organisational justice, we apply structural equation models to test our hypotheses in a sample of 220 employed people with physical disabilities in Andalusia. We show that the perception of discrimination in compensation follows the perception of inequity and mediates the relationship between that perception and job dissatisfaction.     

The experience of teleworking: an annotated review

The paper reviews the contemporary literature on the experience of teleworking. Particular attention is paid to the socializing aspects of work and its comparative absence when working from home; economic considerations, both for homeworkers and for the firms; work satisfaction and motivation; supervision; roles and gender issues in homeworking; the organization of time and space; and, lastly, questions of self-discipline. The evidence reviewed is based on various teleworking trials conducted mainly during the 1980s; this information is supplemented by original research conducted by the authors which investigated the pros and cons raised by British Telecom operators who were due to take part in a teleworking trial. These operators anticipated many of the issues faced by those who actually had teleworking experience.
