Family Change and Continuity in Iran: Birth Control Use Before First Pregnancy

Using data from the 2002 Iran Fertility Transition Survey, we examined birth control use between marriage and first pregnancy. We focused on the post‐1990 increase in birth control use and develop two explanations. The first posits that birth control use reflects a new marriage form, the conjugal marriage, which places a heightened value on the spousal relationship while deemphasizing the centrality of parenthood. A second explanation stresses the use of a new resource, effective birth control, within an Iranian‐Islamist view of marriage. Key to this explanation is the role of the state—Iranian political/religious actors encourage early marriage and the use of birth control. Although the explanations could be complementary, evidence provides more support for the latter.     

From Acute Palliation to Chronic Care: Using the Narratives of Two Gay Caregivers to Explore Experiences of Providing HIV Support Across Sociohistorical Contexts

Despite the longstanding shift in conceptualizing HIV/AIDS as a site of chronic care, versus one of acute palliation, few attempts have been made to examine caregiving in the context of this change. This study constitutes a preliminary attempt at exploring the evolving nature of HIV/AIDS caregiving among sexual minorities, primarily by comparing the narratives of two partnered caregivers of HIV-positive gay men whose stories are located in disparate sociohistorical contexts. Whereas one caregiver provided support during an era in which HIV/AIDS was primarily conceptualized as acutely life-limiting, the other did so in the contemporary period of chronic HIV care. Although similarities are noted across the stories, distinctions are also apparent in how the caregivers encounter expressions of homophobia and HIV stigma, and negotiate these realities distinctly as a function of sociohistorical context. In particular, despite the salience of these systemic barriers across the two narratives, these expressions of marginalization appear to occur more routinely and indefinitely in the context of chronic care. This article concludes with implications of the study's findings on theory, research, policy, and practice.     

Do Shareholders Really Prefer Their Executives to Maximize the Equity Value? A Newsvendor Case*

In this article, we study how the operational decisions of a firm manager depend on her own incentives, the capital structure, and financial decisions in the context of the newsvendor framework. We establish a relationship between the firm’s cost of raising funds and the riskiness of the inventory decisions of the manager. We consider four types of managers, namely, profit, equity, firm value, and profit‐equity maximizers, and initially assume that they may raise funds to increase the inventory level only by issuing debt. We show that the shareholders are indifferent between the different types of managers when the coefficient of variation (CV) of demand is low. However, this is not the case when the CV of demand is high. Based on the demand and the firm’s specific characteristics such as profitability, leverage, and bankruptcy costs, the shareholders might be better off with the manager whose compensation package is tied to the firm value as opposed to the equity value. We, then, extend our model by allowing the manager to raise the required funds by issuing both debt and equity. For this case we focus on the equity and firm value maximizer managers and show that our earlier results (for the debt only case) still hold subject to the cost of issuing equity. However the benefit of the firm value maximizer manager over the equity maximizer manager for shareholders is considerably less in this case compared to the case where the manager can only issue debt. The Board of Directors can take these factors into consideration when establishing/modifying the right incentive package for the managers. We also incorporate the notion of the asymmetric information to capture its impact on the board of directors’ decision about the managers’ incentive package.     

Constructions of Mate Selection Mistakes Among Divorce Applicant Women

This qualitative study aims to explore the patterns and conditions of the wrong decisions women make in choosing their life partners. Grounded theory was employed as the methodological framework. Accordingly, 31 women who had applied for a divorce in the city of Yazd were selected to participate. Purposeful sampling and semistructured interviews were used to select samples and collect data. The findings show wrong decisions in choosing one’s husband were due to heterogeneous partners; emotional, self-willed, and blind decisions; arranged marriages; marriages of convenience; immaturity; conceiving of marriage as an escape from a crisis; dysfunctional parental families; oppressive families; bring destitute; and normative pressure.     

GEE-based zero-inflated generalized Poisson model for clustered over or under-dispersed count data

The zero-inflated regression models such as zero-inflated Poisson (ZIP), zero-inflated negative binomial (ZINB) or zero-inflated generalized Poisson (ZIGP) regression models can model the count data with excess zeros. The ZINB model can handle over-dispersed and the ZIGP model can handle the over or under-dispersed count data with excess zeros as well. Moreover, the count data may be correlated because of data collection procedure or special study design. The clustered sampling approach is one of the examples in which the correlation among subjects could be defined. In such situations, a marginal model using generalized estimating equation (GEE) approach can incorporate these correlations and lead up to the relationships at the population level. In this study, the GEE-based zero-inflated generalized Poisson regression model was proposed to fit over and under-dispersed clustered count data with excess zeros.     

Forecasting before,during, and after recession with singular spectrum analysis

The aim of this research is to apply the singular spectrum analysis (SSA) technique, which is a relatively new and powerful technique in time series analysis and forecasting, to forecast the 2008 UK recession, using eight economic time series. These time series were selected as they represent the most important economic indicators in the UK. The ability to understand the underlying structure of these series and to quickly identify turning points such as the on-set of the recent recession is of key interest to users. In recent years, the SSA technique has been further developed and applied to many practical problems. Hence, these series will provide an ideal practical test of the potential benefits from SSA during one of the most challenging periods for econometric analyses of recent years. The results are compared with those obtained using the ARIMA and Holt–Winters models as these methods are currently used as standard forecasting methods in the Office for National Statistics in the UK.     

Linear rank tests for homogeneity against ordered alternatives in anova and anocova

A unified method of constructing rank tests for homogeneity against ordered alternatives in unbalanced analysis of variance and analysis of covariance is considered. The relationship between these tests with some of the existing methods are studied. The normal theory likelihood ratio tests are also derived and the asymptotic relative efficiency comparisons, in Pitman sense, of the rank tests with respect to the likelihood ratio tests are carried out.     

Distribution-free tests in randomized blocks

Classes of distribution-free tests are proposed for testing homogeneity against order restricted as well as unrestricted alternatives in randomized block designs with multiple observations per cell. Allowing for different interblock scoring schemes, these tests are constructed based on the method of within block rankings. Asymptotic distributions (cell sizes tending to infinity) of these tests are derived under the assumption of homogeneity. The Pitman asymptotic relative efficiencies relative to the least squares statistics are studied. It is shown that when blocks are governed by different distributions, adaptive choice of scores within each block results in asymptotically more efficient tests as compared with methods that ignore such information. Monte Carlo simulations of selected designs indicate that the method of within block rankings is more power robust with respect to differing block distributions.
