The strategic use of Twitter to manage personal public relations

This study examined the effect of personal public relations developed through Twitter on cognitive and attitudinal aspects, particularly focusing on the use of Twitter by CEOs. According to the responses of young consumers who participated in this study, their attitudes toward the use of Twitter by CEOs positively influenced their perception of transformational leadership (H1). Further, perceived transformational leadership was positively associated with attitudes toward CEOs using Twitter; this in turn positively influenced attitudes toward corporations (H2). The positive evaluation of the use of Twitter by CEOs directly influenced attitudes toward such CEOs (H3), whereas attitudes toward such use did not influence attitudes toward corporations. The results indicated that microblogging is beneficial for the development of effective personal public relations by corporate leaders.     

Asymptotic optimality of a two-stage procedure in Bayes sequential estimation

The problem of sequential estimation of the mean with quadratic loss and fixed cost per observation is considered within the Bayesian framework. Instead of fully sequential sampling, a two-stage sampling technique is introduced to solve the problem. The proposed two-stage procedure is robust in the sense that it does not depend on the distribution of outcome variables and the prior. It is shown to be asymptotically not worse than the optimal fixed-sample-size procedures for the arbitrary distributions, and to be asymptotically Bayes for the distributions of one-parameter exponential family.     

The estimation of a corporate crisis communication

This experimental study found a main effect of perceived leadership and an interaction effect of perceived leadership and perceived severity of threats on the public's estimation of organizational crisis responses. The results indicate that the contingent theoretical argument explaining the dynamics of organizational factors and situational factors that determine stance taken by public relations practices can also be applied when explaining the outside latent public's thought patterns predicting an organizational stance and message strategy. Contingency theory offers predictive power, not just for the practitioner, but for the public passing judgment on the stance taken by an organization.     

An investigation of predictors of mental health in single men and women experiencing homelessness in three Canadian cities

Homelessness is related to poorer mental health, yet, there is limited understanding of the predictors of mental health of men and women experiencing homelessness. To support service providers in identifying individuals who might be at particular risk of poor mental health, this study investigated the predictors of mental health in 501 single men and women experiencing homelessness in Vancouver, Toronto, and Ottawa, Canada. Data were obtained via in-person, structured interviews. In order to identify whether predictors differ by gender, multiple linear regressions were conducted separately for men and women. Mental health status was measured by the Mental Component Summary score of the 12-item Short-Form Health Survey. Better mental health for men and women was associated with the presence of fewer chronic health conditions and a higher level of social support. An older age, not having experienced a recent physical attack, and absence of a mental health diagnosis were related to better mental health for women. The absence of unmet mental health needs within the past 12 months was associated with better mental health for men. The study highlights differences in factors associated with mental health for men and women. Service providers should be aware of the association of these factors with mental health to guide assessment and service planning.     

Consistency and dynamic approach of indexes

The purpose of this article is to study two indexes, the marginal index and the Banzhaf–Coleman index. For each of these two indexes, there is a corresponding reduced game that can be used to characterize it. In addition, we consider the efficient extensions of two indexes. In comparison to each characterization of two indexes, we establish a similar characterization for each extension of two indexes through an identical approach. Finally, for each of two efficient indexes, we propose a dynamic process leading to that corresponding efficient index, starting from an arbitrary efficient payoff vector.     

Precise asymptotics in the law of the logarithm for the rescaled range statistic

For a sequence of i.i.d. zero mean random variables belonging to the domain of attraction of the normal law, two results concerning the rescaled range statistic are investigated in this paper. More specifically, we obtain precise asymptotics in the law of the logarithm related to complete convergence and a.s. convergence under some mild conditions.     

In Search of Asian war brides

Because of the long presence of U.S. soldiers in Asia, war-bride marriages involving servicemen and Asian women have been formed throughout the century. The literature, however, contains little empirically sound information on Asian war brides. This analysis develops a methodology to identify war brides and applies it to estimate the number of war brides from the six major Asian groups, using the national 1980 Public Use Microdata Sample. Further analysis comparing Asian war brides with other groups of Asian wives tends to support the traditional and lower socioeconomic images commonly associated with Asian war brides.     

The impact of organizational culture on men's use of parental leave in Sweden

This article examines the impact of organizational culture on men's usage of parental leave in Sweden, a society that promotes men's sharing of childcare. Results from a mail survey of 317 fathers in six companies suggest that men's use of parental leave is significantly affected by organizational culture, including the company's commitment to caring values, the company's level of 'father friendliness', the company's support for women's equal employment opportunity, fathers' perceptions of support from top managers, and fathers' perceptions of work group norms that reward task performance vs. long hours at work. These effects were independent of the influence of individual- and family-level attributes previously acknowledged to affect men's participation in early childcare. While findings support the social constructionist perspective on gender arrangements, men's advocacy of shared parenting and perception of partners' advocacy of shared leave remained strong independent correlates of leavetaking. Fathers can become agents of change within organizations, as they become more supportive of equal parenthood and as they gain rights to longer periods of parental leave that do not need to be negotiated with mothers. Éste articulo evalúa el impacto de la cultura de organizaciones sobre el uso de la baja por paternidad en Suecia, una sociedad que promueve la involucracion de los hombres en el cuidado de niños. Los resultados de una encuesta por correo de 317 padres de familia en seis empresas sugieren que el uso de la baja por paternidad está afectado por la cultura de la organización, incluido la obligación de la empresa en cuanto a valores humanitarios, el nivel de apoyo a los padres (father friendliness), el apoyo por la igualdad de oportunidades por el empleo de mujeres, las percepciones por parte de los padres del nivel de apoyo desde la gerencia alta, y las percepciones por padres de normas de labores de equipo que recompensan el rendimiento de tareas vs. horas largas de trabajo. Estos efectos eran independientes de la influencia de atributos de individuos y familias que anteriormente han sido reconocido por influir la participación de los hombres en el cuidado de niños pequeños. Mientras los resultados apoyan la perspectiva del construccionismo social, el apoyo de los hombres a la participación conjunta en el cuidado de los niños, y sus percepciones de la medida del apoyo por parte de sus parejas acerca del compartir la baja por paternidad/maternidad quedaron en correlación fuerte con la medida de la baja por paternidad. Los padres pueden hacerse agentes de cambio dentro de las organizaciones, mientras apoyan cada vez más la paternidad/maternidad igual y mientras ganan derechos de periodos de permiso mas largos que no tienen que negociarse con las madres.     

Continuous-time capture-recapture models with time variation and behavioural response

This paper develops a likelihood-based inference procedure for continuous-time capture-recapture models. The first-capture and recapture intensities are assumed to be in constant proportion but may otherwise vary arbitrarily through time. The full likelihood is partitioned into two factors, one of which is analogous to the likelihood in a special type of multiplicative intensity model arising in failure time analysis. The remaining factor is free of the non-parametric nuisance parameter and is easily maximized. This factor provides an estimator of population size and an asymptotic variance under a counting process framework. The resulting estimation procedure is shown to be equivalent to that derived from a martingale-based estimating function approach. Simulation results are presented to examine the performance of the proposed estimators.     

An assessment of the accuracy of a regional economic-demographic projection model

A large number of regional economic-demographic projection models have been developed but their accuracy has seldom been evaluated. This article examines the accuracy of one such model in projecting total populations for 1980, using 1970 base data, for 106 counties and 553 places in two states. Comparisons of the model's projections to 1980 Census counts reveal mean percentage absolute differences of 10 percent for counties and 14 percent for places. In addition, the model's accuracy was comparable to that for alternative projection systems. When projections for places of less than 1,000 are excluded, differences are substantially reduced. Economic-demographic models appear to be quite useful and deserve further attention.
