Individual differences and leadership: Contributions to a third tipping point

This commentary describes two tipping points in the history of research on leader individual differences, and suggests the approach of a third. This third tipping point reflects the use of more multivariate (e.g., multiple leader attributes; multistage models; pattern and profile approaches) perspectives to individual differences and leadership. The four papers in the special issue are described as examples of these perspectives.     

Perspective Canada as a social report

This paper reviews the first attempt at social reporting in Canada, Perspective Canada, contrasting it with social reports from other nations, in particular the United States' publication, Social Indicators, 1973. Some future directions and structure for Perspective Canada are suggested, and the paper concludes with a discussion of the importance of the bold use of model building in the analysis of social indicators data, and the innovative use of graphical methods for social reporting.     

Modelling domestic work time

What variables should be used as regressors in models of the length of time which people spend doing unpaid domestic work? To most economists, the answer would be straightforward: use the variables which are implied by a theoretical model of household time allocation (e.g. Becker's). This paper shows that this strategy has not been followed, explores why this is so, and makes some recommendations about variable specification and the treatment of paid market work time in particular. The arguments are illustrated using regressions based on UK time budget data for the mid-1980s.     

Self-Efficacy,Pulmonary Function,Perceived Health and Global Quality of Life of Cystic Fibrosis Patients

This study examined the extent that pulmonary function is related to perceived health status and global quality of life in adults suffering from cystic fibrosis, and the extent that self-efficacy modifies these relationships. Our sample comprised 86 adults (48% female; mean age, 29 years; age range, 18–54 years) with cystic fibrosis, recruited from the Norwegian Competence Centre for Cystic Fibrosis (83% response rate). Both subjective data on psychosocial aspects of living with cystic fibrosis, and objective data on pulmonary function (FEV1%) were assessed. Psychosocial aspects were assessed by a questionnaire that included St George’s Respiratory Questionnaire (perceived health status), the Generalized Self-Efficacy Scale (perceived self-efficacy), and the Quality of Life Scale (global quality of life). We found that self-efficacy is an additional factor explaining health status and global quality of life. Pulmonary function is important for health status, but not for global quality of life, for which perceived self-efficacy and health status are the most significant variables. These results show that self-efficacy is as important as pulmonary function for the perceived health status and global quality of life of patients. These valuable findings should be considered in the treatment and care of adult patients suffering from cystic fibrosis.     

Fertility adaptation of rural-to-urban migrant women: A method of estimation applled to Korean women

This study proposes to test for the existence of an adaptation effect of rural-to-urban migration. The design is to divide migrants into two groups at the time of observation: one group which had migrated by that time, and another group consisting of individuals who had not yet migrated but are known to migrate later. It is presumed that if the former group had not migrated it would have had a birth path similar to the latter group. Adaptation is measured by the difference between this hypothetical birth path and the actual birth path of migrants observed after they migrate. The model is tested on Korean women and found to support the existence of an adaptation effect.     

Perceived Racial Discrimination as a Predictor of Health Behaviors: the Moderating Role of Gender

Perceived racial discrimination (PRD) has been implicated in undermining the mental and physical health of racial/ethnic minorities (e.g., Williams et al. in Am J Public Health 93:200–208, 2003; Wong et al. in J Pers 71:1197–1232, 2003). Researchers have begun to explore the indirect role of health behaviors as one factor in helping to explain this relationship. The goal of the present study was to examine the relationship between PRD and a wide range of health behaviors using a prospective, longitudinal design and to explore the role of gender in moderating these relationships. Using data from the Maryland Adolescent Development in Context Study, we examined the relationship between adolescent PRD (accumulated across ages 14–21) and health behaviors (i.e., diet, substance use, exercise) at age 30 in a sample of middle-class black men and women. Using structural equation modeling, results revealed that more cumulative PRD during adolescence was associated with less healthy eating, more substance use (among men), and more exercise (among women) in young adulthood. Implications of these findings for understanding the role of health behaviors in explaining the link between PRD and health outcomes are considered.     

Principals' perceptions of benefits and barriers to school-based suicide prevention programs

Suicidal behavior among children and adolescents is a national problem and schools can be an effective context for suicide prevention and intervention efforts. School-wide screening programs are viewed as most effective from a public health standpoint, although they garner the least support from school administrators. The purpose of this article is to examine administrators' perceptions of three school-based suicide prevention models while also capturing opinions on barriers and benefits to implementation. Data were gathered through interviews with seven principals from one Midwestern state. Findings reveal agreement among principals that schools play a key role in suicide prevention, but they differ on which type of prevention approach is most appropriate. School principals believed the school-wide screening program included more barriers to implementation than either the in-service or the curriculum-based program, largely due to the likelihood of parental disapproval. Limitations of the study and implications for improving suicide prevention efforts are discussed.     

Commentary: the forgotten older adult with serious mental illness: the final challenge in achieving the promise of Olmstead?

Older adults with serious mental illness disproportionately reside in nursing homes despite the U.S. Supreme Court Olmstead decision supporting the rights of persons with disabilities to benefit from integrated services in the community. This commentary addresses the neglected policy debate on implementing Olmstead for this rapidly growing, older population with special needs. First, the author describes research findings on older adults with serious mental illness living in nursing homes who might more appropriately reside and receive services in the community. Second, the author summarizes the evidence base for effective psychosocial rehabilitation interventions and services facilitating independent living in community settings for this subgroup. Finally, he concludes with seven policy recommendations aimed at advancing the promise of the Olmstead decision with respect to older adults with serious mental illness.     

End-to-end process management: implications for theory and practice

The term ‘end-to-end’ process management is now commonplace in the language and practice of operations. Managers are encouraged to migrate from functional process management to end-to-end process management to realise a range of performance improvements. However, these improvements are often elusive; the specific challenges associated with such a migration are under-researched. This paper uses a cross-sector study to identify the challenges of end-to-end process management and to generate practical managerial guidance. Three areas are identified that demand particular managerial attention: the need to move beyond process mapping, the role of IT in process management and maintaining the process infrastructure as a strategic asset. More significantly, the findings highlight the need for greater conceptual clarity regarding the end-to-end concept itself. The existing literature suggests that scope is the primary differentiator of the end-to-end process – the requirement to manage an extended boundary from customer order through to customer fulfilment. However, this research suggests that the end-to-end concept is more complex, comprising of three core constructs with seven dimensions: scope (boundary conditions, sequence/flow and controls); scale (resources and input/output transformation) and complexity (interrelationships and orientation). End-to-end process management involves much more than an extended boundary. It requires a systemic perspective and clarity regarding controls and transforming resources.     

A grouped beta process model for multivariate resting‐state EEG microstate analysis on twins

EEG microstate analysis investigates the collection of distinct temporal blocks that characterize the electrical activity of the brain. Brain activity within each microstate is stable, but activity switches rapidly between different microstates in a nonrandom way. We propose a Bayesian nonparametric model that concurrently estimates the number of microstates and their underlying behaviour. We use a Markov switching vector autoregressive (VAR) framework, where a hidden Markov model (HMM) controls the nonrandom state switching dynamics of the EEG activity and a VAR model defines the behaviour of all time points within a given state. We analyze the resting‐state EEG data from twin pairs collected through the Minnesota Twin Family Study, consisting of 70 epochs per participant, where each epoch corresponds to 2 s of EEG data. We fit our model at the twin pair level, sharing information within epochs from the same participant and within epochs from the same twin pair. We capture within twin‐pair similarity, using an Indian buffet process, to consider an infinite library of microstates, allowing each participant to select a finite number of states from this library. The state spaces of highly similar twins may completely overlap while dissimilar twins could select distinct state spaces. In this way, our Bayesian nonparametric model defines a sparse set of states that describe the EEG data. All epochs from a single participant use the same set of states and are assumed to adhere to the same state switching dynamics in the HMM model, enforcing within‐participant similarity.
