This is an overview of recent labor immigration in Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates. Attention is given to factors contributing to the dependence of these countries on migrant labor, the impact of the decline in oil revenues, and future trends in the size and skill composition of the foreign labor supply.     

Regression model for surrogate data in high dimensional statistics

Abstract

This paper deals with the problem of estimating the regression of a surrogated scalar response variable given a functional random one. We construct an estimator of the regression operator by using, in addition to the available (true) response data, a surrogate data. We then establish some asymptotic properties of the constructed estimator in terms of the almost-complete and the quadratic mean convergences. Notice that the obtained results generalize a part of the results obtained in the finite dimensional framework. Finally, an illustration on the applicability of our results on both simulated data and a real dataset was realized. We have thus shown the superiority of our estimator on classical estimators when we are lacking complete data.     

A Hybrid Methodology for Modeling Risk of Adverse Events in Complex Health‐Care Settings

In spite of increased attention to quality and efforts to provide safe medical care, adverse events (AEs) are still frequent in clinical practice. Reports from various sources indicate that a substantial number of hospitalized patients suffer treatment‐caused injuries while in the hospital. While risk cannot be entirely eliminated from health‐care activities, an important goal is to develop effective and durable mitigation strategies to render the system “safer.” In order to do this, though, we must develop models that comprehensively and realistically characterize the risk. In the health‐care domain, this can be extremely challenging due to the wide variability in the way that health‐care processes and interventions are executed and also due to the dynamic nature of risk in this particular domain. In this study, we have developed a generic methodology for evaluating dynamic changes in AE risk in acute care hospitals as a function of organizational and nonorganizational factors, using a combination of modeling formalisms. First, a system dynamics (SD) framework is used to demonstrate how organizational‐level and policy‐level contributions to risk evolve over time, and how policies and decisions may affect the general system‐level contribution to AE risk. It also captures the feedback of organizational factors and decisions over time and the nonlinearities in these feedback effects. SD is a popular approach to understanding the behavior of complex social and economic systems. It is a simulation‐based, differential equation modeling tool that is widely used in situations where the formal model is complex and an analytical solution is very difficult to obtain. Second, a Bayesian belief network (BBN) framework is used to represent patient‐level factors and also physician‐level decisions and factors in the management of an individual patient, which contribute to the risk of hospital‐acquired AE. BBNs are networks of probabilities that can capture probabilistic relations between variables and contain historical information about their relationship, and are powerful tools for modeling causes and effects in many domains. The model is intended to support hospital decisions with regard to staffing, length of stay, and investments in safety, which evolve dynamically over time. The methodology has been applied in modeling the two types of common AEs: pressure ulcers and vascular‐catheter‐associated infection, and the models have been validated with eight years of clinical data and use of expert opinion.     

An Empirical Analysis of Life Jacket Effectiveness in Recreational Boating

This article gives a measure of life jacket (LJ) effectiveness in U.S. recreational boating. Using the U.S. Coast Guard's Boating Accident Report Database from 2008 to 2011, we find that LJ wear is one of the most important determinants influencing the number of recreational boating fatalities, together with the number of vessels involved, and the type and engine of the vessel(s). We estimate a decrease in the number of deceased per vessel of about 80% when the operator wears their LJs compared to when they do not. The odds of dying are 86% higher than average if the accident involves a canoe or kayak, but 80% lower than average when more than one vessel is involved in the accident and 34% lower than average when the operator involved in the accident has more than 100 hours of boating experience. Interestingly, we find that LJ effectiveness decreases significantly as the length of the boat increases and decreases slightly as water temperature increases. However, it increases slightly as the operator's age increases. We find that between 2008 and 2011, an LJ regulation that requires all operators to wear their LJs—representing a 20% increase in wear rate—would have saved 1,721 (out of 3,047) boaters or 1,234 out of 2,185 drowning victims. The same policy restricted to boats 16–30 feet in length would have saved approximately 778 victims. Finally, we find that such a policy would reduce the percentage of drowning victims compared to other causes of death.     

Voices of girls with disabilities in rural Iran

This paper investigates the interaction of gender, disability and education in rural Iran, which is a relatively unexplored field of research. The responses of 10 female students with disabilities from Isfahan indicated that the obstacles they faced included marginalization, difficulties in getting from home to school, difficulties within the school building itself, and discrimination by teachers, classmates and school authorities. The data collected for the study contain a wide range of conservative gendered discourses, and show how traditional gender beliefs interact with disability to aggravate the problems faced in education by young women with disabilities. It is hoped that the findings will raise awareness among policy-makers of the many formidable obstacles that make it difficult for young women with disabilities to achieve their full potential in education.     

Organizational emotional capability,product and process innovation,and firm performance: An empirical analysis

The concept of emotional capability is one of the competencies that a firm has which is vital for the daily life of the organization. However, the effect of emotional capability, involving the dynamics of encouragement, displaying freedom, playfulness, experiencing, reconciliation, and identification constructs on the firm innovativeness (i.e., product and process) is interestingly missing in the technology and innovation management (TIM) literature. In this study, by investigating 163 Turkish firms, the dynamics of encouragement and experiencing were found to have a positive association with both firm product and process innovativeness; and the dynamics of displaying freedom have a positive relationship with firm process innovativeness. We also demonstrate that the impact of emotional capability constructs on firm innovativeness is contingent upon environmental uncertainty. Specifically, we find that the influence of the dynamics of encouragement on firm product innovation increases with increased rate of environmental uncertainty. Interestingly, the relationship between the dynamics of experiencing and product innovation across low, medium, and high levels of environmental uncertainty is an ∩-shaped. And, the relationship between the dynamics of displaying freedom and product innovation across low, medium, and high levels of environmental uncertainty is a U-shaped. In addition, we show that a firm's emotional capability influences its financial and market performance via firm innovativeness. We discuss the theoretical and managerial implications of the study's findings.     

A response to criticism of our estimates of under-5 mortality in Iraq, 1980–98

According to estimates published in this journal, the number of deaths of children under 5 in Iraq in the period 1991–98 resulting from the Gulf War of 1991 and the subsequent imposition of sanctions by the United Nations was between 400,000 and 500,000. These estimates have since been held to be implausibly high by a working group set up by an Independent Inquiry Committee appointed by the United Nations Secretary-General. We believe the working group's own estimates are seriously flawed and cannot be regarded as a credible challenge to our own. To obtain their estimates, they reject as unreliable the evidence of the 1999 Iraq Child and Maternal Mortality Survey—despite clear evidence of its internal coherence and supporting evidence from another, independent survey. They prefer to rely on the 1987 and 1997 censuses and on data obtained in a format that had elsewhere been rejected as unreliable 30 years earlier.     

Mass Media Campaign Impacts Influenza Vaccine Obtainment of University Students

Abstract

Objective: To describe the effectiveness of a mass media campaign in increasing the rate of college student influenza vaccine obtainment. Participants/Methods: Students (N = 721) at a large southern university completed a survey between September 2011 and January 2012 assessing what flu clinic media sources were visualized and if they encouraged them to obtain vaccination. Results: Nearly a 30% increase was seen in flu vaccination rates in Fall 2011 over Fall 2010. The main campus Web site portal was the most visualized media source among students. The majority of responses indicated that the source of information visualized had a moderate to strong influence over their decision to get vaccinated. Conclusions: Various communication channels should be utilized to increase influenza vaccination rate on a university campus. Use of mass media to influence college students to perceive, retain, and act on the message of obtaining the influenza vaccine did produce a noteworthy outcome.     

Asymptotic normality of a robust estimator of the regression function for functional time series data

We propose a family of robust nonparametric estimators for a regression function based on the kernel method. We establish the asymptotic normality of the estimator under the concentration property on small balls probability measure of the functional explanatory variable when the observations exhibit some kind of dependence. This approach can be applied in time series analysis to make prediction and build confidence bands. We illustrate our methodology on the US electricity consumption data.
