The Relationship Between Information System Planning Sophistication and Information System Success: An Empirical Assessment*

Literature on information systems (IS) planning implicitly assumes that a sophisticated IS planning process leads to greater IS success. This paper questions the exclusive reliance on this traditional belief. Instead, because IS planning requires significant organizational resources, prior IS success is essential to convince top management of the importance of IS planning sophistication. Therefore, IS success may influence IS planning sophistication. Several theoretical arguments are advanced in support of this explanation. Data from a survey of 236 academic institutions are used to empirically assess the two alternative directions of the relationship between IS planning sophistication and IS success. Four structural models including the alternative causal directions are evaluated. Two of these models are supported. Together, they imply that for a high level of IS planning sophistication, either the previous ISs should have been successful or the organization should possess advanced information technology capabilities. Thus, empirical results suggest that the explanation presented here (i.e., IS success facilitates IS planning sophistication) provides an equally good alternative to the more traditional explanation (i.e., IS planning sophistication facilitates IS success).

The persistence of skin color discrimination for immigrants

Under Title VII of the Civil Rights Act of 1964, discrimination in employment on the basis of color is prohibited, and color is a protected basis independent from race. Using data from the spouses of the main respondents to the New Immigrant Survey 2003, this paper shows that immigrants with the lightest skin color earn on average 16-23% more than comparable immigrants with the darkest skin color. These estimates control for years of legal permanent residence in the US, education, English language proficiency, occupation in source country, Hispanic or Latino ethnicity, race, country of birth, as well as for extensive current labor market characteristics that may be themselves influenced by discrimination. Furthermore, the skin color penalty does not diminish over time. These results are consistent with persistent skin color discrimination affecting legal immigrants to the United States.     

Competitive Priorities in Operations Management

Identifying manufacturers' competitive priorities has long been considered a key element in manufacturing strategy research. However, relatively little effort has been devoted to measurement of these constructs in published research. In this study we develop scales for commonly accepted competitive priorities, cost importance, quality importance, delivery-time importance, and flexibility importance. We assess how well the scales capture the constructs that they represent using data collected from 114 manufacturing plants in the United States. The findings suggest that the instrument developed can provide reliable data and that the constructs measured are valid. In addition, comparisons between pairs of informants representing the same business indicate that the perceptual measures of competitive priorities are as reliable as point estimates of routine, seemingly objective information.     

The intergenerational transmission of divorce in cross-national perspective: Results from the Fertility and Family Surveys

We used data on women's first marriages from the Fertility and Family Surveys to analyse the intergenerational transmission of divorce across 18 countries and to seek explanations in macro-level characteristics for the cross-national variation. Our results show that women whose parents divorced have a significantly higher risk of divorce in 17 countries. There is some cross-national variation. When compared with the USA, the association is stronger in six countries. This variation is negatively associated with the proportion of women in each cohort who experienced the divorce of their parents and with the national level of women's participation in the labour force during childhood. We conclude that differences in the contexts in which children of divorce learn marital and interpersonal behaviour affect the strength of the intergenerational transmission of divorce.     

Religious Influences on the Risk of Marital Dissolution

This study examined multiple dimensions of religious involvement and the risk of divorce among a nationwide sample of 2,979 first‐time married couples. Multivariate proportional hazards modeling was used to analyze two waves of the National Survey of Families and Households. Results indicated that although each partner's religious attendance bore a modest relationship to marital dissolution, the risk of divorce was lower if husbands had conservative theological beliefs and when both partners belonged to mainline Protestant denominations. Conversely, the risk of divorce was elevated if husbands attended services more frequently than their wives and if wives were more theologically conservative than their husbands. These patterns withstood controls for sociodemographic covariates, marital duration, and marital quality. Directions for future research are discussed.     

A model based approach for predicting annual poverty rates without expenditure data

The primus inter pares of the UN-approved Millennium Development Goals is to reduce poverty. The only internationally accepted method of estimating poverty requires a measurement of total consumption based on a time-consuming and resource-demanding measure of household expenditure in an integrated survey over 12 months. Rather than measuring poverty, say, only every fifth year, a model is presented to predict poverty based on a small set of household variables to be collected annually between two 12-monthly household surveys. Information obtained from these “light” surveys might then be used to predict poverty rates. The key question is whether the inaccuracy in these predictions is acceptable. It is recommended that these models be tested at a country level and if the test results are similar to those found here, that this approach be adopted.      

抽样调查下样本随机性的检验

 抽样调查下样本随机性的检验,不是考查抽样方法的优劣或是检查样本代表性的好坏,而是为了控制抽样调查的数据质量,检验所得样本和抽样方法的一致性,即调查机构是否严格按照抽样设计的要求去抽取样本。本文以等概率和不等概率抽样为例,揭示了如何利用相关辅助信息,构造检验统计量,进行样本随机性的检验。     

Does it matter how you ask? Question wording and males’ reporting of contraceptive use at last sex

This paper reports results from a unique experiment conducted in the 2002 National Survey of Family Growth (NSFG) to gauge the effect of question format on men’s reports of contraceptive use at last sexual intercourse. Respondents received separate questions about their own and their partners’ contraceptive use or one combined question about either partner’s contraceptive use. We examine whether receiving separate questions, as opposed to one combined question, is related to higher reports of using any contraceptive method, specific methods, female methods in addition to male methods, and the number of methods reported. We find that reports of any contraceptive use at last sex and use of the most common methods, condoms and the pill, were stable across question formats. However, we find significantly higher reports of withdrawal, combining male and female methods, and multiple method use among men who received the separate-question format. We also find that characteristics of the sexual experience in question condition the effect of question format on men’s reports.
