Relationship of bird richness,abundance and assemblage to the built environment in a small island tropical urban setting: a Suva,Fiji case study

There have been few studies investigating the relationship between the built environment and the status of bird distributions in small island tropical urban areas. We present a study investigating the relationship between bird species richness, abundance and assemblage to the built environment in Suva, Fiji. Field surveys were taken at 54 randomly selected sites throughout the city, stratified by three building density classes and the central business district (CBD). At each site bird counts were recorded, along with environmental data such as average building height, within a 150 m radius. Land-use information was obtained from screen digitized high-resolution satellite imagery within the same radius. Distance to undeveloped patches of land within the urban area was calculated using a GIS. Analysis of the effects of the built environment was carried out for all species, and for exotic and native species separately. Abundance of exotics was significantly higher in the central business district (CBD) than all other urban density classes, and significantly higher than natives in all other density classes. We found a negative relationship between native species richness and distance to undeveloped patches, but no relationship for exotics. Species assemblage was not related to urban density class. We conclude that the status of native and exotic bird species in Suva is similar to what has been found in urban areas in temperate climates, and conservation efforts should focus on minimizing the amount of heavily urbanized “core areas” and protecting undeveloped areas of forested vegetation to improve bird biodiversity in small tropical islands cities.

     

Comfort with discussions about death,religiosity, and attitudes about end‐of‐life care

In end‐of‐life (EOL) care research, death anxiety and religiosity are often overlooked. Terror management theory (TMT) may provide a useful conceptual model with which to examine how comfort discussing death and religiosity influence attitudes related to EOL care. A telephone‐based survey was conducted among community‐dwelling adults in the Unites States. Via random sampling, with over‐sampling of Hispanics/African Americans, 123 completed survey interviews (response rate = 46%) were analyzed. Respondents were more likely to have better attitudes toward EOL care if they were older or white, religiously active, and comfortable with the subject of death. Religiosity and comfort discussing death were correlated with each other and remained significant predictors of attitudes about EOL care even without demographic covariates. Findings suggest that promoting an open dialogue about mortality may improve attitudes about EOL care and utilization of palliative care services. The study also provides evidence about the utility and applicability of TMT for EOL care.     

Participatory shaping of community futures in e‐waste processing hubs: Complexity,conflict and stewarded convergence in a Palestinian context

This article describes an unconventional participatory development approach carried out in an informal e‐waste hub in South‐West Hebron, an area that has collected and processed the bulk of Israeli e‐waste for over a decade. Our approach contributes to the critique and recovery of community representation in participatory development and the search for ways to facilitate representative community engagement. Specifically, we describe our use of a novel Delphi‐like method that allowed us to facilitate a broadly endorsed development trajectory within a heterogeneous and conflicted community. We show how the results yielded by this approach diverged from those that were likely to emerge from more facile forms of participation in ways that are important for other similar e‐waste hubs internationally, which face a destructive status quo on the one hand, or the economically ruinous international policies that ban e‐waste trade from “developed” to “developing” countries on the other. Despite real tensions and cleavages within the affected communities, the process described facilitated a shift from deadlocked environmental versus livelihood positions towards building capacity and regulating existing informal e‐waste trades to preserve livelihoods dependent on these.     

Social cognition,social neuroscience,and evolutionary social psychology: What's missing?

In this paper I argue that something important, and something social, is missing from contemporary accounts of social cognition, social neuroscience and evolutionary social psychology. Contemporary accounts of social cognition focus on cognition directed towards social objects, that is, towards persons and social groups. In contrast, early twentieth century accounts of socially engaged cognition focused upon beliefs and attitudes oriented to the represented beliefs and attitudes of members of social ‘reference groups’ and directed towards both social and non‐social objects. I argue that this earlier conception of socially engaged cognition should be integrated with contemporary research on social cognition, social neuroscience and evolutionary social psychology, since it poses a challenge but also an opportunity for these disciplines.     

‘Surrounded with so much uncertainty’: asylum seekers and manufactured precarity in Australia

In Australia, nearly 30,000 asylum seekers have the legal right to work, but their temporary and conditional migration status exposes them to work-related precarity. This article draws on a small qualitative study that examined asylum seekers’ experiences of seeking work and achieving economic security. Over an 18-month period, 29 semi-structured interviews with asylum seekers who had work rights in Australia were conducted. It provides insights into how restrictive immigration policies manufacture precarity through short-term, conditional visas, resulting in employer risk aversion, segmentation into insecure work, and in-work instability and mistreatment. Asylum seekers manage their experiences and feelings of pervasive insecurity through individual coping and survival strategies.     

AN ANALYSIS OF CAPACITY PLANNING PROCEDURES FOR A MATERIAL REQUIREMENTS PLANNING SYSTEM*

This paper is concerned with planning work-center capacity levels in manufacturing firms that employ a material requirements planning (MRP) system. It presents four procedures for developing work-center capacity plans designed to insure the production of components and assemblies as specified by the MRP plan and the master production schedule (MPS). These procedures (capacity planning using overall factors, capacity bills, resource profiles, and capacity requirements planning) are compared using simulation analysis. The results indicate that the performance of a procedure when measured against the MPS depends on the operating conditions of the manufacturing system. The results also indicate that the choice of a particular procedure often represents a compromise among the benefits of improved MPS performance, the costs of preparing and processing data, and the premium expenses required for more frequent adjustments in work-center capacity levels.     

THE EFFECT AND COST OF FORECAST ERROR BIAS FOR MULTIPLE-STAGE PRODUCTION-INVENTORY SYSTEMS

This paper examines forecast error with an intention not to minimize forecast error so much as to bias the resultant error in order to achieve better managerial results. Much work has been accomplished by other researchers toward the goal of minimizing forecast error—sometimes by the use of sophisticated forecasting techniques. The results of this paper indicate that manipulating forecast error bias may be the better managerial strategy as opposed to going to great lengths to minimize forecast error. Subject Areas: Forecasting, Aggregate Planning, Capacity Planning, and Production/Operations Management.     

A CANONICAL ANALYSIS OF MANAGERIAL-ENVIRONMENTAL RELATIONSHIPS: IMPLICATIONS FOR METHODOLOGY AND POLICY*

The present study uses canonical analysis to examine the contingency model of organizations in the nursing home field. Data on environmental pressures and managerial practices relevant to the decision-making process are analyzed. Results support the theory that managerial practices are contingent on environmental pressures. The implications of these results for health-care decision makers and for future assessments of managerial-environmental relationships are discussed.     

ON THE SOLUTION OF SPATIAL EQUILIBRIUM MODELS*

Recent advances in mathematical programming methods and computing technology have the potential for overcoming the many formidable barriers to the widespread solution of nonlinear spatial models. In particular, the recent public availability of the software package MINOS/AUGMENTED has major implications for both policy and theoretical research involving spatial models. In this paper, mathematical programming formulations of two highly nonlinear spatial models are provided, model solutions presented, and associated computational experience discussed. In addition, related work is discussed briefly and suggestions are advanced concerning the potential role of the package in furthering the objectives of this related work. Subject Areas: Mathematical Programming, Transportation, and Urban and Regional Planning.
