A Field Study of RFID Deployment and Return Expectations

Radio Frequency Identification (RFID) technology promises to transform supply chain management. Building on previous research in information systems and supply chain management, this paper proposes a theoretical framework for RFID adoption and benefits, and tests the framework using data on u. s. firms. Our analysis suggests that there is a positive association between information technology (IT) application deployment and RFID adoption. We find that RFID implementation spending and partner mandate are associated with an expectation of early return on RFID investment, and a perceived lack of industry‐wide standards is associated with an expectation of delayed return on RFID investment. These results suggest that firms with broad IT application deployment and a critical mass of RFID implementation spending are more likely to report early returns from RFID deployments. This paper extends previous research to understand the relationship between organization characteristics and adoption and expected benefits of the emerging RFID technology.     

Process of Intergenerational Ambivalence: A Qualitative Inquiry

The phenomena of intergenerational ambivalence are often explained in terms of autonomy versus dependency, conflicting norms between generation regarding role expectation in intergenerational relations, and there has been a tendency to believe these factors lead to intergenerational ambivalence. This article intends to explain the family interaction processes that leads to the ambivalence type of relationships. A purposive sample of 185 respondents from 48 families was randomly selected from urban and rural area. The sample comprised father, son, mother-in-law, and daughter-in-law within the joint family. Data were collected through a narrative method and analyzed with a structure model analysis. The data reveal that in the process of interaction, generations have similarities in functional process (physical, economic, and emotional support) but have differences in normative (fulfillment of familial obligation, role, and responsibility) and consensual processes (differences in values and attitude). These differences can lead to negative subjective experiences in terms of stress and strain. Thus, to avoid such situations, participants often used emotion-focused coping approaches also maintaining ambivalence with respect to their intergenerational relationships.     

Asymptotic properties of a quast-maximum likelihood estimator in truncated regression model with serial correlation

Robinson (1982a) presented a general approach to serial correlation in limited dependent variable models and proved the strong consistency and asymptotic normality of the quasi-maximum likelihood estimator (QMLE) for the Tobit model with serial correlation, obtained under the assumption of independent errors. This paper proves the strong consistency and asymptotic normality of the QMLE based on independent errors for the truncated regression model with serial correlation and gives consistent estimators for the limiting covariance matrix of the QMLE.     

Generalizing Clatworthy group divisible designs

In this paper a neat construction is provided for three new families of group divisible designs that generalize some designs from Clatworthy's table of the only 11 designs with two associate classes that have block size four, three groups, and replication numbers at most 10. In each case (namely, _λ1=4${\lambda }_1=4$ and _λ2=5${\lambda }_2=5$, _λ1=4${\lambda }_1=4$ and _λ2=2${\lambda }_2=2$, and _λ1=8${\lambda }_1=8$ and _λ2=4${\lambda }_2=4$), we have proved that the necessary conditions found are also sufficient for the existence of such GDD's with block size four and three groups, with one possible exception.     

Why do Emerging Market Firms Engage in Voluntary Environmental Management Practices? A Strategic Choice Perspective

In this paper, we investigate firms’ decisions to engage in voluntary environmental management (VEM) practices within an emerging market context. Drawing on the strategic choice and the resource‐based view perspectives, we report results from a survey of VEM practices – a specific form of self‐governance – drawing on a sample of 519 Turkish firms from various industries to identify important strategic antecedents of firms’ decisions to engage in such practices. We find that as firms become more customer focused, more inclined to pursue a differentiation strategy and subject to a higher level of strategy‐oriented stakeholder focus, they tend to implement higher levels of VEM practices, with important implications for research, policy and practice for both emerging and developed markets.     

Identifying underlying principles in social work law: A teaching and learning approach to the legal framework of decision making

Courses in social work law need to ensure that students know, understand and can apply specific rules of law. However, the sheer volume of law affecting social work and the rapidity with which that law changes require courses in social work law not just to ensure that, but that they are equipped to manage changes in the law. In order to be able to do this, it is argued, the general principles underlying those individual legal rules need to be identified and understood. Students and practitioners need to have educational and professional skills at a higher level of transferability than merely acquiring knowledge of specific legal rules can provide. We use the legal framework of decision making to explain the importance of this approach. The principles of administrative law have been identified as a major component in social work law, and, despite limited exposition in social work law texts, we outline the teaching and learning strategy we have pursued in relation to this topic. |em|We argue that there are thus both educational and practice based reasons for the approach advocated, which we also believe accord with wider imperatives of social work education.     

Threshold Incentives and Sales Variance

In this paper, we analyze the impact of two forms of commonly used threshold‐based incentive schemes on the observed sales variability. The first form of the incentive comprises an additional marginal payment on crossing a specified sales threshold and the second form of the incentive scheme comprises a lumpsum bonus payment on crossing the predetermined sales threshold. We model the effect of such incentives under two specific scenarios: an exclusive dealership selling a single product and a non‐exclusive dealer selling two competing products. For an exclusive dealer, we show that a bonus contract not only increases the expected sales, but, more importantly, decreases the sales (order) variance. Consequently, the bonus‐based scheme allows the manufacturer to regulate sales variance better. With a non‐exclusive dealer, the sales variance increases substantially with an additional marginal payment contract. However, our analysis suggests that the bonus contract continues to perform better in this case, too, if the threshold level is set appropriately using the underlying demand distribution.     

An efficient nonparametric test for bivariate two-sample location problem

We propose a new test for the two-sample bivariate location problem. The proposed test statistic has a U-statistic representation with a degenerate kernel. The limiting distribution is found for the proposed test statistic. The power of the test is compared using Monte Carlo simulation to the tests of Blumen [I. Blumen, A new bivariate sign-test for location, Journal of the American Statistical Association 53 (1958) 448–456], Mardia [K.V. Mardia, A non-parametric test for the bivariate two-sample location problem, Journal of the Royal Statistical Society, Series B 29 (1967) 320–342], Peters and Randles [D. Peters, R.H. Randles, A bivariate signed-rank test for the two-sample location problem, Journal of the Royal Statistical Society, Series B 53 (1991) 493–504], LaRocque, Tardif and van Eeden [D. LaRocque, S. Tardif, C. van Eeden, An affine-invariant generalization of the Wilcoxon signed-rank test for the bivariate location problem, Australian and New Zealand Journal of Statistics 45 (2003) 153–165], and Baringhaus and Franz [L. Baringhaus, C. Franz, On a new multivariate two-sample test, Journal of Multivariate Analysis 88 (2004) 190–206]. Under the bivariate normal and bivariate t distributions the proposed test was more powerful than the competitors for almost every change in location. Under the other distributions the proposed test reached the desired power of one at a faster rate than the other tests in the simulation study. Application of the test is presented using bivariate data from a synthetic and a real-life data set.     

Vertical and Lateral Information Processing: The Effects of Gender, Employee Classification Level, and Media Richness on Communication and Work Outcomes

Data from 666 employees of a large midwesterntelephone company were analyzed to identifycommunication pattern differences between: (a) males andfemales; (b) exempt and nonexempt employees; and (c)employees using rich and lean communication media. MANOVAand discriminant function analyses results indicatedfemales sent less information to supervisors andexperienced less information overload than males. Exempt employees interacted more with department headsand sent less information to peers than nonexemptemployees. Those using the richest media communicatedmore with supervisors while those using the leanest media received most of their information fromdepartment heads. Additionally, interaction effects weredetected. Discussion is advanced on how these findingsmight be used to improve intraorganizational communication.
