Does Culture Affect Divorce? Evidence From European Immigrants in the United States

This article explores the role of culture in determining divorce by examining country-of-origin differences in divorce rates of immigrants in the United States. Because childhood-arriving immigrants are all exposed to a common set of U.S. laws and institutions, we interpret relationships between their divorce tendencies and home-country divorce rates as evidence of the effect of culture. Our results are robust to controlling for several home-country variables, including average church attendance and gross domestic product (GDP). Moreover, specifications with country-of-origin fixed effects suggest that immigrants from countries with low divorce rates are especially less likely to be divorced if they reside among a large number of coethnics. Supplemental analyses indicate that divorce culture has a stronger impact on the divorce decisions of females than of males, pointing to a potentially gendered nature of divorce taboos.     

Long-term safety of stimulant medications used to treat children with ADHD

Attention-deficit/hyperactivity disorder (ADHD) is a common mental health condition that affects children, adolescents, and adults. Because it is a chronic condition and typically requires effective treatment for several years or more, information on the benefits and risks of long-term pharmacotherapy for ADHD is vital to clinicians. This article reviews the emerging literature on the safety of long-term stimulant medications in ADHD-the most commonly prescribed medications for this condition. Common side effects, including cardiovascular effects, growth effects, and tics, are discussed, as well as treatment of children younger than age 6 and evidence of carcinogenic and reproductive effects.     

Socioeconomic Status,Income Inequality,and Health Complaints: A Basic Psychological Needs Perspective

Socioeconomic status (SES) and income inequality are now recognized as important determinants of health, and there is growing interest in uncovering the intermediary psychosocial pathways through which the socioeconomic context affects physical well-being (Marmot in The status syndrome: how social standing affects our health and longevity, Henry Holt, New York, 2004; Wilkinson and Pickett in The Spirit Level: why more equal societies almost always do better, Allen Lane, London, 2009). We adopted the applied framework of self-determination theory (SDT; Deci and Ryan in Psychol Inq 11:227–268, 2000) and hypothesized that fulfillment of the basic psychological needs for autonomy, competence, and relatedness would mediate the relationships that SES and income inequality have to self-rated health. An online community sample of American participants (N = 1,139) completed a detailed demographic survey and provided self-reports of need fulfillment and health complaints. Structural equation models controlled for impression management and self-deceptive enhancement. Controlling for sex and age, need fulfillment was predicted positively by subjective SES and objective household income and negatively by state-level income inequality; in turn, need fulfillment predicted lower levels of health complaints. These findings suggest that SDT provides a useful framework for the study of SES, income inequality, and health, and that basic psychological needs are an important mechanism through which socioeconomic contexts influence health.     

Maintaining the Professional Integrity of Federal Statistics

Transactional analysis can be used to analyze personal interactions between consulting statisticians and their clients. The Parent-Adult-Child model has recently been refined to consist of six states by subdividing the Parent and Child ego states. The authors briefly define the six ego states (Nurturing Parent, Critical Parent, Adult, Adapted Child, Free Child, and Rebellious Child) and describe their occurrence during statistical consultations. Recommendations are given for identifying the ego states, setting realistic goals for relationships, and modifying unsatisfactory transactions.     

The Interpretation of Coefficients in Models with Qualitative Dependent Variables*

A substantial body of empirical accounting, finance, management, and marketing research utilizes single equation models with discrete dependent variables. Generally, the interpretation of the coefficients of the exogenous variables is limited to the sign and relative magnitude. This paper presents three methods of interpreting the coefficients in these models. The first method interprets the coefficients as marginal probabilities and the second method interprets the coefficients as elasticities of probability. The third method utilizes sensitivity analysis and examines the effect of hypothetical changes in exogenous variables on the probability of choice. This paper applies these methods to a published research study.     

Equilibrium Wage Dispersion with Worker and Employer Heterogeneity

We construct and estimate an equilibrium search model with on–the–job–search. Firms make take–it–or–leave–it wage offers to workers conditional on their characteristics and they can respond to the outside job offers received by their employees. Unobserved worker productive heterogeneity is introduced in the form of cross–worker differences in a “competence” parameter. On the other side of the market, firms also are heterogeneous with respect to their marginal productivity of labor. The model delivers a theory of steady–state wage dispersion driven by heterogenous worker abilities and firm productivities, as well as by matching frictions. The structural model is estimated using matched employer and employee French panel data. The exogenous distributions of worker and firm heterogeneity components are nonparametrically estimated. We use this structural estimation to provide a decomposition of cross–employee wage variance. We find that the share of the cross–sectional wage variance that is explained by person effects varies across skill groups. Specifically, this share lies close to 40% for high–skilled white collars, and quickly decreases to 0% as the observed skill level decreases. The contribution of market imperfections to wage dispersion is typically around 50%.     

The Impact of Trade on Intra‐Industry Reallocations and Aggregate Industry Productivity

This paper develops a dynamic industry model with heterogeneous firms to analyze the intra‐industry effects of international trade. The model shows how the exposure to trade will induce only the more productive firms to enter the export market (while some less productive firms continue to produce only for the domestic market) and will simultaneously force the least productive firms to exit. It then shows how further increases in the industry's exposure to trade lead to additional inter‐firm reallocations towards more productive firms. The paper also shows how the aggregate industry productivity growth generated by the reallocations contributes to a welfare gain, thus highlighting a benefit from trade that has not been examined theoretically before. The paper adapts Hopenhayn's (1992a) dynamic industry model to monopolistic competition in a general equilibrium setting. In so doing, the paper provides an extension of Krugman's (1980) trade model that incorporates firm level productivity differences. Firms with different productivity levels coexist in an industry because each firm faces initial uncertainty concerning its productivity before making an irreversible investment to enter the industry. Entry into the export market is also costly, but the firm's decision to export occurs after it gains knowledge of its productivity.

Digital internal communication: An interplay of socio-technical elements

Digital transformation has become a research focus in recent years. Likewise, internal communication (IC) is one of the fastest-growing specialisations in public relations and communication management. This research explores digital internal communication (DIC) at the nexus between digital transformation and IC. We provide an integrative review of the literature; our thematic analysis of selected journal articles and other scholarly texts is guided by the concept of organisations as socio-technical systems. Furthermore, we create a template using NVivo software to organise the emerging themes and clusters following the logic of communication levels. This template allows us to explain the phenomenon of DIC in a socio-technical organisational system and discuss how the emerging themes are interrelated, people-focused, and linked to competency development and trust-building. As a contribution to theory, we offer a conceptual model which illustrates the dynamics of DIC as an interplay of socio-technical elements on three communication levels. This conceptual model can be further developed in scholarly discussions on DIC and by organisations reflecting on their IC use in a digital workplace environment.
