To help evaluate the risk of process reengineering failure and enhance the prospect of its success, three potential sources of influence on BPR initiatives and success are examined in this study. These include the innovative capacity of the organization, IS maturity and strategy-IS interface. It was found that while factors related to IT maturity and influence such as experience in mainframe and client/server computing may facilitate the decision to reengineer, they are not critical in the later stages of the initiative. On the other hand, factors having significant relationships beyond the initial decision include variables pertaining to innovative capacity of the organization and strategy-IS interface. These findings suggest that technical IT competence as a critical enabler is necessary but not sufficient for reengineering success. Based on study findings regarding the innovative capacity of the organization, guidelines for reengineering risk assessment are proposed. In addition, implications of the findings, limitations of the study and opportunities for further research are also discussed.  相似文献

German law (§ 2079 of the Civil Code) provides for the rescission of a generally binding joint will or contract of inheritance if a surviving spouse has remarried. The law assumes that the spouse has been mistaken in the motivation for making the will. If the surviving spouse has not remarried, but cohabited with a new partner, the rescission may similarly be effected by applying § 2078 par. 2 of the Civil Code. The live-in partner will benefit from the rescission if the surviving spouse has named him or her as the successor of the deceased spouse. He or she may indeed have a right of rescission even if the partner has died without rescinding the joint will.  相似文献

Recent innovations in the structure of formal organizations suggest possible directions for the design of schools to bring about high achievement. The structure of output-driven in contrast to administratively-driven schools is described, and designs are described which address both the goal of high achievement and the goal of reduced inequality.An earlier version of this paper was presented as the author's Sorokin Lecture at the annual meeting of the Eastern Sociological Society, Boston, March 1993.  相似文献

Cross-cultural comparisons of norms derived from research on Death Anxiety are valid as long as they provide existential validity. Existential validity is not empirically derived like construct validity. It is an understanding of being human unto death. It is the realization that death is imminent. It is the inner sense that provides a responder to death anxiety scales with a valid expression of his or her sense about the prospect of dying. It can be articulated in a life review by a disclosure of one's ontology. This article calls upon psychologists who develop death anxiety scales to disclose their presuppositions about death before administering a questionnaire. By disclosing his or her ontology a psychologist provides a means of disclosing his or her intentionality in responding to the items. This humanistic paradigm allows for an interactive participation between investigator and subject. Lester, Templer, and Abdel-Khalek (2006-2007) enriched psychology with significant empirical data on several correlates of death anxiety. But all scientists, especially psychologists, will always have alternative interpretations of the same empirical fact pattern. Empirical data is limited by the affirmation of the consequent limitation. A phenomenology of language and communication makes existential validity a necessary step for a broader understanding of the meaning of death anxiety.  相似文献

Radio frequency identification (RFID) has been used to improve business supply chain management for over 35 years. As often happens, private sector technology migrates to the public sector where it is adapted for use. RFID use in governments is spreading far and wide at the federal and state levels with virtually no debate or performance analyses to inform adoption decisions. Implementation of RFID technology impacts government efficiency and effectiveness in many areas. Data show that most RFID applications promise enhanced effectiveness but also pose increased costs. A model is constructed to assist state and local managers in choosing to adopt RFID and to discern the status and impacts of this bold new innovation.

We use data from the Fragile Families and Child Wellbeing Study to investigate the association between coparenting quality and nonresident fathers' involvement with children over the first five years after a nonmarital birth. We find that about one year after a nonmarital birth, 48% of fathers are living away from their child, rising to 56% and then to 63% at three and five years, respectively Using structural equation models to estimate cross-lagged effects, we find that positive coparenting is a strong predictor of nonresident fathers' future involvement, whereas fathers' involvement is only a weak (but significant) predictor of future coparenting quality. The positive effect of coparenting quality on fathers' involvement is robust across several techniques designed to address unobserved heterogeneity and across different strategies for handling missing data. We conclude that parents' ability to work together in rearing their common child across households helps keep nonresident fathers connected to their children and that programs aimed at improving parents' ability to communicate may have benefits for children irrespective of whether the parents' romantic relationship remains intact.  相似文献

The existing literature on marriage and fertility decisions pays little attention to the roles played by risk preferences and uncertainty. However given uncertainty regarding the availability of suitable marriage partners, the ability to contracept, and the ability to conceive, women's risk preferences might be expected to play an important role in marriage and fertility timing decisions. By using data from the Panel Study of Income Dynamics (PSID), I find that measured risk preferences have a significant effect on the timing of both marriage and fertility. Highly risk-tolerant women are more likely to delay marriage, consistent with either a search model of marriage or a risk-pooling explanation. In addition, risk preferences affect fertility timing in a way that differs by marital status and education, and that varies over the life cycle. Greater tolerance for risk leads to earlier births at young ages, consistent with these women being less likely to contracept effectively. In addition, as the subgroup of college-educated, unmarried women nears the end of their fertile periods, highly risk-tolerant women are likely to delay childbearing relative to their more risk-averse counterparts and are therefore less likely to become mothers. These findings may have broader implications for both individual and societal well-being.  相似文献
