Structure of the public relations/communication department: Key findings from a global study

This paper reports on some of the core findings from a program of research focused on examining the structure of public relations/communication departments. It draws on a recent major global study that was sponsored by the former Research Foundation of the International Association of Business Communicators (IABC). Analyzing the results from interviews with 26 Chief Communication Officers (CCOs) located in each of the five continents and from a survey sample of some 278 CCOs based in organizations headquartered across the globe, the study found quite notable variations in the type of departmental structures. No one dominant structural model emerged. In effect, each organization appeared to adopt a structural design to suit their individual circumstances, although there were nevertheless some reasonably common component functional elements within each department. CCOs identified those variables that they believed most influenced the design of the public relations department structure. While recognizing department structure is situation dependent, the evidence suggests that CCOs create hybrid structures unique to the circumstances. What was perhaps most surprising was that department structure did not appear to be strongly influenced by department size, other than in terms of the vertical structural design. In short, there do not appear to be any common formulas or prescribed solutions for how organizations should or do orchestrate the design of the public relations department structure, rather CCOs appear to be able to exercise a degree of latitude in determining what works best for them.     

Evaluation of hip abductor and adductor strength in the elderly: a reliability study

Background

In elderly individuals an increased muscle strength contributes to the diminution of the falls risk and associated adverse events. An increasing interest in lateral control exists due to the fatal consequences of postero-lateral falls. Therefore a proper assessment of frontal plane hip muscle strength in elderly is important but remains challenging.Therefore we aimed to investigate the feasibility and repeatability of a hip abductor and adductor maximum voluntary isometric strength (MVIS) and rate of force generation (RFG) test in elderly. This represents an initial step in the development process of a new and clinically relevant test that could lead to more specific treatment protocols for this population.

Methods

In this measurement focused study hip abduction (ABD) and adduction (ADD) MVIS and RFG were tested twice within one to three hours with a dynamometer fixed to a custom made frame in a geriatric population including fallers and non-fallers. Intraclass correlation coefficient (ICC_agreement), standard error of measurement (SEM), and smallest detectable difference (SDD) were determined.

Results

All recruited persons (N?=?76; mean age (SD) 80.46 (7.05) years old) completed the tests. The average time needed to complete the strength tests was 10.58 min. (1.56) per muscle group. The reliability of the hip ABD and ADD was high with ICC’s_agreement ranging from 0.83 to 0.97. The SDD varied between 18.1 and 81.8% depending on the muscle group and type of strength that was evaluated.

Conclusion

Hip abductor and adductor strength measures in older person are feasible and reliable. However, the significance of moderate changes in these measurements may be limited by the large SDD and SEM. Therefore, physical therapist should be careful when using this measure for assessing the progress of an individual person in a daily clinical use.

     

The impact of family owners’ monitoring on CEO turnover decisions and the role of trust

Even though there is clear evidence that large shareholders play an effective monitoring role over poorly-performing CEOs, the monitoring of family owners is yet quite unexplored. This study investigates the impact of family ownership on the CEO turnover-performance sensitivity, examining two potential factors that can affect the ability of the family owners in ensuring a prompt replacement of an underperforming CEO. First, we examine whether the monitoring of family owners is weakened by the existence of family ties with CEO. Second, we investigate whether the monitoring of family owners over professional CEOs is affected by the cultural propensity to trust or distrust a stranger. Our findings show that family owners are able to ensure a prompt replacement of an underperforming CEO only when the CEO is not a family member but rather an outside professional. Moreover, we find that the effectiveness of the family’s monitoring over professional CEO is weaker in environments characterized by the cultural propensity to distrust a stranger, rather than in contexts characterized by the cultural feeling to trust an outsider.     

Usability study of a vineyard teleoperated compost spreader

Teleoperation has been widely applied in modern industry because of a variety of advantages, such as providing replaceable surrogates for humans in dangerous or difficult working environments over long distances. In this paper, a usability evaluation study of a teleoperation system for a compost spreader robotic machine is presented. The machine has been designed for the application of compost in small and stepping parcels of hilly vineyards. Driving and working tasks can be controlled remotely by a portable piloting unit, reducing the risk for the operator in the event of machine overturning. Participants of the study were asked to perform a series of tasks and sub-tasks and to vocalize their thoughts while working with the machine. The tasks were designed to simulate typical user experience. Once all the tasks were accomplished each participant was asked to fill a questionnaire. The evaluation considered aspects such as learnability, ease of use, understandability, controllability, frustration, mental effort, distraction, clarity of presentation, perceived usefulness, temporal efficiency and machine aesthetic. Results show that usability evaluation helped detecting design deficiencies in the teleoperated compost spreader machine.     

Halo and association effects: Cognitive biases in teacher attunement to peer‐nominated bullies,victims, and prosocial students

This study examined whether teachers’ perceptions of students’ behavior (referring to halo effects) and the behavior of teacher‐perceived friends (referring to association effects) influenced teachers’ ability to recognize students identified as bullies, victims, and prosocial by their peers. Data came from 1,458 children (M_age = 10.5, 47.5% girls) and 56 teachers (M_age = 40.8, 66.1% females). Perceived likeability was associated with decreased odds and teachers’ perceptions of popularity and externalizing behavior were associated with increased odds for teacher attunement to bullying. Perceived likeability and affiliation were associated with decreased odds for teacher attunement to victimized students. Teachers’ perceptions of externalizing behavior were associated with decreased odds, whereas teachers’ perceptions of affiliation and academic competence were associated with increased odds for attunement to prosociality. Finally, a positive association was found between teacher attunement and the average behavior of teacher‐perceived friends for bullying, victimization, and prosociality.

Frequentist and Bayesian Interval Estimators for the Normal Mean

It is well known that a Bayesian credible interval for a parameter of interest is derived from a prior distribution that appropriately describes the prior information. However, it is less well known that there exists a frequentist approach developed by Pratt (1961 Pratt , J. W. ( 1961 ). Length of confidence intervals . J. Amer. Statist. Assoc. 56 : 549 – 657 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) that also utilizes prior information in the construction of frequentist confidence intervals. This frequentist approach produces confidence intervals that have minimum weighted average expected length, averaged according to some weight function that appropriately describes the prior information. We begin with a simple model as a starting point in comparing these two distinct procedures in interval estimation. Consider X ₁,…, X _n that are independent and identically N(μ, σ²) distributed random variables, where σ² is known, and the parameter of interest is μ. Suppose also that previous experience with similar data sets and/or specific background and expert opinion suggest that μ = 0. Our aim is to: (a) develop two types of Bayesian 1 ? α credible intervals for μ, derived from an appropriate prior cumulative distribution function F(μ) more importantly; (b) compare these Bayesian 1 ? α credible intervals for μ to the frequentist 1 ? α confidence interval for μ derived from Pratt's frequentist approach, in which the weight function corresponds to the prior cumulative distribution function F(μ). We show that the endpoints of the Bayesian 1 ? α credible intervals for μ are very different to the endpoints of the frequentist 1 ? α confidence interval for μ, when the prior information strongly suggests that μ = 0 and the data supports the uncertain prior information about μ. In addition, we assess the performance of these intervals by analyzing their coverage probability properties and expected lengths.     

Psychological Wellbeing Among Same‐sex Attracted and Heterosexual Parents: Role of Connectedness to Family and Friendship Networks

Increasing numbers of lesbian, gay and bisexual (LGB) adults are entering into parenthood. Previous studies indicate many of these parents receive little or no support from their families of origin due to family members' negative attitudes toward homosexuality. This study looks at the extent to which LGB parents report a lower sense of connectedness to family of origin and friendship networks than heterosexual parents and whether this has an impact on psychological wellbeing in either of these groups. Data were derived from two studies of parents: Work, Love, Play, a study of Australian and New Zealand LGB parents (n=324); and the Longitudinal Study of Australian Children, a population‐based study of young children and parents (n=6460). Structural equation modelling was used to explore the relationships between: parent sexuality and family/friendship connectedness, family/friendship connectedness and psychological wellbeing, parent sexuality and psychological wellbeing. LGB parents reported feeling less connected to their families of origin but more connected to their friendship groups than heterosexual parents. Counter to previous studies, we found no difference in the psychological wellbeing of LGB parents compared to heterosexual parents when examining the direct effect of sexuality on psychological wellbeing. Clinical implications for counsellors and family therapists are discussed.     

Utilitarian,managerial and relational theories of corporate social responsibility

Concepts and theories of corporate social responsibility (CSR) have been examined and classified by scholars since the mid‐1970s. However, owing to the evolving meaning of CSR and the huge number of scholars who have begun to analyze the issue in recent years fresh efforts are needed to understand new developments. Since there is a great heterogeneity of theories and approaches, the task remains a very hard one, mainly because heterogeneity derives from multi‐disciplinary diversity. The criterion for selection is to consider the role that theorists confer to the firm. Following this idea, three groups of theories have been discerned: (1) the utilitarian group, in which the corporation is intended as a maximizing ‘black box’ where problems of externalities and social costs emerge; (2) the managerial category, where problems of responsibility are approached from inside the firm (internal perspective); (3) relational theories, or those in which the type of relations between the firm and the environment are at the center of the analysis. The three perspectives allow the reader to understand the most significant differences between the various theories of CSR. The objective is to classify the theories and to draw a map in which group specificities can be made available. This allows scholars to reach a better understanding of corporate–society relations, and enhances developments both in theoretical and empirical terms.
