The downside of organizational identification: Relations between identification,workaholism and well-being

Abstract

Employee organizational identification has been proposed and found to be positively related to employee health and well-being. The empirical evidence, however, is not unequivocal, and some authors have suggested possible downsides of identification with the organization as a whole or with a group within it. The potential negative effect of over-identification was tested empirically for the first time in the present paper. Two studies were conducted; Study 1 was cross-sectional and used a sample of Italian law court clerks (N=195) and Study 2 was longitudinal and employed a sample of Italian teachers (N=140 at T2). We proposed a curvilinear mediation model with identification curvilinearly predicting workaholism, and workaholism, in turn, negatively affecting employee well-being. This curvilinear link between organizational identification and workaholism means that workaholism at first decreases with growing identification, but when identification becomes too strong, workaholism increases. The results confirmed our hypotheses, and we discuss theoretical and practical implications.     

Xenophobic attacks, migration intentions, and networks: evidence from the South of Africa

We investigate how emigration from a developing region is affected by xenophobic violence at destination. Based on a unique household survey collected in Mozambique in summer 2008, a few months after a series of xenophobic attacks in South Africa that killed dozens and displaced thousands of immigrants from neighboring countries, we estimate migration intentions of Mozambicans before and after the attacks, controlling for a placebo period. We focus on the role of family and social networks in the sending community in shaping changes in the expressed intentions to migrate. We find that the migration intention of household heads decreases after the violence, especially for those household heads with many children whose families have no access to social networks. The results illustrate that networks at origin insure risks related to migration and that, when deciding to migrate, workers tend to care more about the future of their offspring than their own health.     

Semiparametric Estimates of Monetary Policy Effects: String Theory Revisited

We develop flexible semiparametric time series methods for the estimation of the causal effect of monetary policy on macroeconomic aggregates. Our estimator captures the average causal response to discrete policy interventions in a macrodynamic setting, without the need for assumptions about the process generating macroeconomic outcomes. The proposed estimation strategy, based on propensity score weighting, easily accommodates asymmetric and nonlinear responses. Using this estimator, we show that monetary tightening has clear effects on the yield curve and on economic activity. Monetary accommodation, however, appears to generate less pronounced responses from both. Estimates for recent financial crisis years display a similarly dampened response to monetary accommodation.     

A survival analysis of the last great European plagues: The case of Nonantola (Northern Italy) in 1630

This paper develops the first survival analysis of a large-scale mortality crisis caused by plague. For the time-to-event analyses we used the Cox proportional hazards regression model. Our case study is the town of Nonantola during the 1630 plague, which was probably the worst to affect Italy since the Black Death. Individual risk of death did not depend on sex, grew with age (peaking at ages 40–60 and then declining), was not affected by socio-economic status, and was positively associated with household size. We discuss these findings in light of the historical–demographic and palaeo-demographic literature on medieval and early modern plagues. Our results are compatible with the debated idea that ancient plague was able to spread directly from human to human. Our methods could be replicated in other studies of European plagues to nuance and integrate the findings of recent palaeo-biological and palaeo-demographic research on plague.     

The connectivity of ethnic displays: new codes for identity in northern Laos

In Laos, cultural festivals and other forms of ethnic display communicate locality and ethnicity to external agencies, in particular the nation state. This article documents strategies of identity-making in a small festival that was staged spontaneously in a Rmeet (Lamet) village. The chosen representations were conventional: dance, music, clothing. The Rmeet thereby employed a festival code used by numerous minorities worldwide. But these recently invented traditions are continuous with earlier representations that addressed various categories of strangers, including historic states and non-state groups. What has changed is the connectivity of the representations. Dance or costume used to represent external relationships in the past, but have been recoded for present use. Moreover, Rmeet have appropriated a New Year’s festival invented by the neighboring Khmu. Thus, ethnic displays appear as the most recent way of communicating difference in a code that connects them with the state, neighboring ethnicities, and a global language of locality.     

Trunk stabilization with sling training in osteoporosis patients—a randomized clinical trial

Fractures due to osteoporosis are one of the principal causes of functional limitations, chronic pain, and greater morbidity in advanced age. In addition to bone risk factors for osteoporotic fractures include extraosseous causes such as falls or reduced neuromuscular capacity. Muscle and coordination exercises enhance the patients’ abilities in daily life and prevent falls. In view of recent conclusions drawn from competitive sports, which stress the significance of the muscles of the trunk in respect of reducing back pain and optimizing posture, we used sling exercises to determine whether osteoporosis patients benefit from it and whether it is more advantageous than traditional physiotherapy. Fifty patients were randomized into two groups. Group A received traditional physiotherapy, while group B was given sling exercises, in each case twice a week for a period of 3 months. The results of treatment (pre-post) were analyzed in terms of pain levels, mobility, trunk strength, and the shape of the back. After a further 3 months with no specific exercise treatment, we retested all patients in order to draw conclusions about the long-term effects of the two types of exercise. Forty-four patients (88 %) completed the study. Patients were assigned to small groups (a maximum of five patients in each group) and, thus, received individual attention and motivation. Positive training effects were achieved in both groups. Significantly better results as regards improvement of mobility and reduction of falls were registered in the sling exercise group.     

My parents taught Me. Evidence on the family transmission of values

The paper uses questions included in the 2010 wave of the Bank of Italy’s Survey on Household Income and Wealth to investigate the role of family transmission of values. It presents three main empirical findings. First, the paper shows that a number of attitudes (generalized and personalized trusting behaviour, risk and time preferences) and outcomes (female labour force participation, fertility, entrepreneurship, productivity) are associated with the values received. Second, it documents that values received from parents are correlated with the values transmitted to descendants. Third, by using respondent moving patterns, the paper highlights that values received are slowly changing even after a discontinuity in the reference environment. Comparisons between first- and second-generation movers suggest that what matters for breaking the family chains are the formative years, when young people somehow strike a balance between the values transmitted by their parents and what they experience in the (possibly different) environment where they grow up.     

Efficient Estimation of Average Treatment Effects Using the Estimated Propensity Score

We are interested in estimating the average effect of a binary treatment on a scalar outcome. If assignment to the treatment is exogenous or unconfounded, that is, independent of the potential outcomes given covariates, biases associated with simple treatment‐control average comparisons can be removed by adjusting for differences in the covariates. Rosenbaum and Rubin (1983) show that adjusting solely for differences between treated and control units in the propensity score removes all biases associated with differences in covariates. Although adjusting for differences in the propensity score removes all the bias, this can come at the expense of efficiency, as shown by Hahn (1998), Heckman, Ichimura, and Todd (1998), and Robins, Mark, and Newey (1992). We show that weighting by the inverse of a nonparametric estimate of the propensity score, rather than the true propensity score, leads to an efficient estimate of the average treatment effect. We provide intuition for this result by showing that this estimator can be interpreted as an empirical likelihood estimator that efficiently incorporates the information about the propensity score.     

Modeling of interventions for reducing external Enterobacteriaceae contamination of broiler carcasses during processing

This article presents a mathematical model for the Enterobacteriaceae count on the surface of broiler chicken during slaughter and how it may be affected by different processing technologies. The model is based on a model originally developed for Campylobacter and has been adapted for Enterobacteriaceae using a Bayesian updating approach and hitherto unpublished data gathered from German abattoirs. The slaughter process in the model consists of five stages: input, scalding, defeathering, evisceration, washing, and chilling. The impact of various processing technologies along the broiler processing line on the Enterobacteriaceae count on the carcasses’ surface has been determined from literature data. The model is implemented in the software R and equipped with a graphical user interface which allows interactively to choose among different processing technologies for each stage along the processing line. Based on the choice of processing technologies the model estimates the Enterobacteriaceae count on the surface of each broiler chicken at each stage of processing. This result is then compared to a so-called baseline model which simulates a processing line with a fixed set of processing technologies. The model calculations showed how even very effective removal of bacteria on the exterior of the carcass in a previous step will be undone by the cross-contamination with leaked feces, if feces contain high concentrations of bacteria.     

Liquidity and Trading Dynamics

In this paper, we build a model where the presence of liquidity constraints tends to magnify the economy's response to aggregate shocks. We consider a decentralized model of trade, where agents may use money or credit to buy goods. When agents do not have access to credit and the real value of money balances is low, agents are more likely to be liquidity constrained. This makes them more concerned about their short‐term earning prospects when making their consumption decisions and about their short‐term spending opportunities when making their production decisions. This generates a coordination element in spending and production which leads to greater aggregate volatility and greater comovement across producers.
