Newborn Infants' Preference for Attractive Faces: The Role of Internal and External Facial Features

Several previous experiments have found that newborn and young infants will spend more time looking at attractive faces when these are shown paired with faces judged by adults to be unattractive. Two experimental conditions are described with the aim of finding whether the “attractiveness effect” results from attention to internal or external facial features, or both. Pairs of attractive and less attractive faces (as judged by adults) were shown to newborn infants (mean age 2 days, 9 hours), where each pair had either identical internal features (and different external features) or identical external features (and different internal features). In the latter, but not the former, condition the infants looked longer at the attractive faces. These findings are clear evidence that newborn infants use information about internal facial features in making preferences based on attractiveness. It is suggested that when newborn (and older) infants are presented with facial stimuli, whether dynamic or static, they are able to attend both to internal and external facial features.     

The influences of relationship quality with external partners and required levels of approval of messaging on crisis preparedness

As funding for public health promotion is increasingly limited in the U.S., public relations research informing management of crises that threaten public health is especially critical. Crisis planning models such as Reynolds and Seeger’s (2005, 2014) crisis and emergency risk communication model offer comprehensive directives for crisis managers and present opportunities to extend the utility of best practice recommendations. A survey of public information officers (PIOs) (n=208) at local public health departments across the U.S. examines the quality of their relationships with partners in public health crisis management, including first responders, media, law enforcement, and hospitals, and reveals that relationships with key publics in crisis management are lacking. Further, PIOs at state governed health departments may face critical delays in releasing crisis messages, as their messages are required to clear more levels of approval than locally (city/county) governed departments. Implications and future research for these key variables extending public relations crisis communication research with a focus on inter-organizational relationships are discussed.     

A GIS Analysis of East Asian Care Gaps in Residential and Assisted Living Facilities in Vancouver,Canada

Residential care and assisted living services provide support to seniors who may not have the ability to live independently. However, East Asian residents often do not have sufficient access to culturally specific activities, which may result in psychosocial stress and isolation. This study presents a geographic analysis method to evaluate spatial distribution of culturally tailored senior care facilities in Metro Vancouver. We identify geographical disparities, indicating that many East Asian seniors have poor local access to a culturally tailored facility. We recommend the use of geographical analysis techniques to improve the analysis and planning for senior care in an increasingly diverse population.     

Professional feminists: Challenging local government inside out

Gender equality work in local government carried out during the 1980s presents a valuable site to explore the interaction between professional and feminist working. In the history of the Women's Liberation Movement (WLM) and feminist organizing more broadly in the UK, professional working has often been positioned as antithetical to feminist working, and relatively little scholarship has examined the interface between the two. This article argues that the individuals involved should be considered ‘professional feminists’ as opposed to ‘femocrats’, drawing from across feminist, social movement and organizational theory, and interviews carried out in 2011 and archival texts from three UK councils. It also suggests their work (undertaken between the beginning of the 1980s and the beginning of the 1990s) serves to blur the boundaries usually marked between social movement and state. This contributes to the existing literature by exploring the specific understandings and practices put to work by those working on gender equality professionally, but not in an elected capacity, within local government, and how their work can be positioned in relation to feminist organizing more broadly.     

Visualizing the landscape and evolution of leadership research

Complementing prior quantitative and qualitative reviews of the leadership literature, we conduct a bibliometric analysis of leadership articles. Our bibliometric review provides a different perspective by portraying the landscape and developmental trajectory of leadership research over time via co-citation and co-occurrence analyses. Using a scientific visualization tool CiteSpace and 6528 leadership works collected from the Web of Science database from 1990 to 2017, we detect and visualize the landscape of leadership research and track how this landscape has evolved. After mapping the landscape, we discuss the insights gleaned from our bibliometric review, with a focus on open questions, future research directions, and implications. In doing so, our review provides readers with a systematic understanding of the development of the leadership field and a roadmap to spark leadership research and move this literature forward.     

Variance estimation for integrated population models

State-space models are widely used in ecology. However, it is well known that in practice it can be difficult to estimate both the process and observation variances that occur in such models. We consider this issue for integrated population models, which incorporate state-space models for population dynamics. To some extent, the mechanism of integrated population models protects against this problem, but it can still arise, and two illustrations are provided, in each of which the observation variance is estimated as zero. In the context of an extended case study involving data on British Grey herons, we consider alternative approaches for dealing with the problem when it occurs. In particular, we consider penalised likelihood, a method based on fitting splines and a method of pseudo-replication, which is undertaken via a simple bootstrap procedure. For the case study of the paper, it is shown that when it occurs, an estimate of zero observation variance is unimportant for inference relating to the model parameters of primary interest. This unexpected finding is supported by a simulation study.     

Partitioning the effects of habitat fragmentation on rodent species richness in an urban landscape

Habitat fragmentation plays a major role in species extinction around the globe. Previous research has determined that species richness in fragments is affected by a number of characteristics. These include fragment age, size, and isolation, edge effects, vegetation coverage, habitat heterogeneity, and matrix content. Although most studies focused on one or a few of these characteristics, multiple characteristics work together to affect species richness, showing that the effects of habitat fragmentation are complex. The goal of our study was to partition the complex effects of habitat fragmentation by determining the direct, indirect, and cumulative effects of multiple habitat fragment characteristics on rodent species richness. In 2013, we determined rodent species richness in 25 habitat fragments within Thousand Oaks, California. In addition, we measured the following characteristics for each fragment: fragment age, area, isolation, shrub coverage, habitat heterogeneity, perimeter/area ratio, and percent non-urban buffer. Path Analysis was used to test the hypothesized model which described the direct, indirect, and cumulative effect of each habitat fragment characteristic on rodent species richness. Overall, the path model explained 67 % of the variation in rodent species richness among habitat fragments. Habitat heterogeneity had the greatest direct and total effect on rodent species richness. Fragment size had the next greatest total effect on rodent species richness but this was nearly entirely indirect through its influence on habitat heterogeneity, suggesting that large fragments containing the greatest diversity of habitats will support the most species. Our study shows that large habitat fragments support the greatest habitat diversity, which provides the highest likelihood of conserving rodent species richness in an urban landscape.
