Dual-language characteristics and earnings: Male Mexican workers in the United States

This paper examines income differentials between native-born white males of non-Hispanic origins and Mexican American males of varying linguistic statuses. The analysis relies on conventional modeling techniques of the earnings process and the selected use of mother tongue, English fluency, and primary language usage to categorize the Mexican American population. The findings differ among the derived groups. Among Mexican immigrants, there does not appear to be any direct economic reward for speaking English. For the U.S.-born Chicanos, there is only a small economic advantage associated with being reared as an English monolingual, and there appears to be a clear disadvantage directly associated with being a Spanish-dominant bilingual.     

Syllabus review: procedures for strengthening racial,ethnic, and gender-related curriculum content

The issue of how one school of social work in the United States approached the systematic incorporation of racial/ethnic and gender-related content in its curriculum is the subject of this paper. American accreditation standards on curriculum content of the above issues are discussed, as are the impact of this process on the school's curriculum as well as increased faculty awareness.     

The ties that bind? Social networks of nursing staff and staff's behaviour towards residents with dementia

This study investigated social networks of nursing staff and staff's behaviour towards residents with dementia. We focused on two types of networks: communication networks among staff, and networks between nursing staff and relatives/acquaintances of residents. Data was collected in 37 long-term care units in nursing- and residential homes in the Netherlands.     

The Stigma of Privilege: Racial Identity and Stigma Consciousness Among Biracial Individuals

Racial identification is a complex and dynamic process for multiracial individuals, who as members of multiple racial groups have been shown to self-identify or be identified by others differently, depending on the social context. For biracial individuals who have white and minority ancestry, such identity shifting (e.g., from minority to white, or vice versa) may be a way to cope with the threats to their racial identity that can be signaled by the presence or absence of whites and/or minorities in their social environment. We examine whether stigma consciousness (Pinel in J Pers Soc Psychol 76(1):114–128, 1999; i.e., the chronic awareness of the stereotyping and prejudice that minorities face) interacts with the sociocultural context to predict social identity threat, belonging, and racial identification. Using experience sampling methodology, minority/white biracial individuals (27 Asian/white, 22 black/white, and 26 Latino/white) reported the racial composition of their environment, social identity threat for their component racial identities, overall feelings of belonging, and racial identification over a 1-week period. Results suggest that stigma consciousness predicts the extent to which biracial people identify with their white background and experience belonging in different racial contexts. We discuss racial identity shifting in response to context-based threats as a protective strategy for biracial people, and identity where participants’ sociocultural contexts and experiences with racial identity and threat differ as a result of their minority racial group or ascribed race.     

Sins of the parents: Self-control as a buffer between supervisors' previous experience of family undermining and subordinates' perceptions of abusive supervision

Drawing upon social learning theory, the intergenerational transmission of violence hypothesis, and research on self-control, we develop a model of the relationships among previous experiences of family undermining, self-control, and abusive supervision. We tested the model with data obtained from supervisor–employee matched pairs in Study 1 and matched triads in Study 2. Results revealed that: 1) supervisors who experienced higher levels of family undermining (whether reported by the immediate supervisor or a sibling) during childhood are more likely to engage in abusive supervisory behaviors as adults; and 2) this relationship is moderated such that it is stronger for supervisors with low self-control. Overall, our results highlight the role of self-control in mitigating the impact of supervisors' previous experiences of family undermining on subordinate perceptions of abusive supervision, even after controlling for previously established antecedents.     

Application of Correspondence Analysis in the Assessment of Mine Tailings Dam Breakage Risk in the Mediterranean Region

A new statistical approach for preliminary risk evaluation of breakage in tailings dam is presented and illustrated by a case study regarding the Mediterranean region. The objective of the proposed method is to establish an empirical scale of risk, from which guidelines for prioritizing the collection of further specific information can be derived. The method relies on a historical database containing, in essence, two sets of qualitative data: the first set concerns the variables that are observable before the disaster (e.g., type and size of the dam, its location, and state of activity), and the second refers to the consequences of the disaster (e.g., failure type, sludge characteristics, fatalities categorization, and downstream range of damage). Based on a modified form of correspondence analysis, where the second set of attributes are projected as "supplementary variables" onto the axes provided by the eigenvalue decomposition of the matrix referring to the first set, a "qualitative regression" is performed, relating the variables to be predicted (contained in the second set) with the "predictors" (the observable variables). On the grounds of the previously derived relationship, the risk of breakage in a new case can be evaluated, given observable variables. The method was applied in a case study regarding a set of 13 test sites where the ranking of risk obtained was validated by expert knowledge. Once validated, the procedure was included in the final output of the e-EcoRisk UE project (A Regional Enterprise Network Decision-Support System for Environmental Risk and Disaster Management of Large-Scale Industrial Spills), allowing for a dynamic historical database updating and providing a prompt rough risk evaluation for a new case. The aim of this section of the global project is to provide a quantified context where failure cases occurred in the past for supporting analogue reasoning in preventing similar situations.     

The Rationality of Under‐employing the Best‐performing Soccer Players

Abstract. This paper analyses the influence of sport performance (productivity) and other variables measuring the economic contribution of soccer players, upon the coach's decision of selecting a particular player. Using as dependent variable the proportion of time that individuals play in the Spanish professional soccer league, the paper concludes that players' economic market value does significantly affect the coach's choice, revealing the existence of other aims different from maximizing sport performance. We also examine the type of discrimination associated with lower chances of playing, which leads to smaller earnings and poorer career opportunities. The empirical evidence does not support discrimination due to nationality.     

Convergence of the Guesstimation Algorithm

Economists attempting to build econometric or forecasting models are frequently restricted due to data scarcity in terms of short time series of data, and also of parameter non constancy and under-specification. In this case, a realistic alternative is often to guess rather than to estimate parameters of such models. An algorithm of repetitive guessing (drawing) parameters from iteratively changing distributions, with the objective of minimizing the squares of ex-post prediction errors, weighted by penalty weights and subject to a learning process, has been recently introduced. Despite obvious advantages, especially when applied for undersized empirical models with a large number of parameters, applications of Repetitive Stochastic Guesstimation have been, so far, limited. This has presumably been caused by the lack of rigorous proof of its convergence. Such proof for a class of linear models, both identifiable (in the economic sense) and not, is provided in this article.     

The macroeconomic impact of reforming a PAYG system: The Portuguese case

Abstract   The article analyses the impact of various types of reform options on social security pension system financial sustainability and on a range of macroeconomic variables. The HERPOR model is used to consider the likely effects of parametric reforms of the existing pay-as-you-go system, as well as those of a systemic reform. The article concludes that the former are sufficient to ensure financial sustainability, although they should be accompanied by employment implementation measures. The article concludes that a fully pre-funded system does not seem to be a viable option for policy-makers in the redesigning of social security pension systems, due to the high transition costs involved.
