Patterns of resource allocation are reliable among younger and older readers.

Younger and older adults read short expository passages across 2 times of measurement for subsequent comprehension or recall. Regression analysis was used to decompose word-by-word reading times into resources allocated to word- and textbase-level processes. Readers were more sensitive to these demands when reading for recall than when reading for comprehension. Patterns of resource allocation showed good test-retest reliabilities and were predictive of memory performance. Within age group, resource allocation parameters were not systematically correlated with other individual-difference measures, suggesting that strategies of on-line resource allocation may be a unique source of individual differences in determining comprehension of and memory for text. Age differences in allocation patterns appeared to reflect general slowing among the older adults. Because older adults showed equivalent memory performance to that of younger readers, the reading time data may represent the on-line resource allocation needed for comparable outcomes among older and younger readers.

Job resources buffer the impact of job demands on burnout.

This study tested and refined the job demands-resources model, demonstrating that several job resources play a role in buffering the impact of several job demands on burnout. A total of 1,012 employees of a large institute for higher education participated in the study. Four demanding aspects of the job (e.g., work overload, emotional demands) and 4 job resources (e.g., autonomy, performance feedback) were used to test the central hypothesis that the interaction between (high) demands and (low) resources produces the highest levels of burnout (exhaustion, cynicism, reduced professional efficacy). The hypothesis was rejected for (reduced) professional efficacy but confirmed for exhaustion and cynicism regarding 18 out of 32 possible 2-way interactions (i.e., combinations of specific job demands and resources).

Culture as a resource for mental health.

This article is based on the author's address at the National Multicultural Conference and Summit III in Los Angeles, California, in January 2003. The author focuses on culture as a resource--a resource for theories that can inform one's understanding of human behavior; a resource for healing, self-help, and positive emotions; a resource for clinical practice; and a resource for mental health and wellness. The author uses a healing story from native culture to describe the essence of his relational worldview and to reframe the professional thinking about culture as one of the greatest assets for healing and mental wellness rather than as a problem to solve.

Resource-based niches provide a basis for plant species diversity and dominance in arctic tundra.

Ecologists have long been intrigued by the ways co-occurring species divide limiting resources. Such resource partitioning, or niche differentiation, may promote species diversity by reducing competition. Although resource partitioning is an important determinant of species diversity and composition in animal communities, its importance in structuring plant communities has been difficult to resolve. This is due mainly to difficulties in studying how plants compete for below-ground resources. Here we provide evidence from a 15N-tracer field experiment showing that plant species in a nitrogen-limited, arctic tundra community were differentiated in timing, depth and chemical form of nitrogen uptake, and that species dominance was strongly correlated with uptake of the most available soil nitrogen forms. That is, the most productive species used the most abundant nitrogen forms, and less productive species used less abundant forms. To our knowledge, this is the first documentation that the composition of a plant community is related to partitioning of differentially available forms of a single limiting resource.

A model of resource needs of aging spinal cord injured men.

It has always been understood that those who deal effectively with a disability call upon special resources that members of the able bodied population are not required to develop. However, the nature and relationship of these resources to aging outcomes is as yet only superficially understood. The present study provides further information and clarification about the resources needed for aging with a spinal cord injury. The sample consists of 70 individuals who have had a spinal cord injury for at least 15 years, and who are currently over the age of 45, and are therefore either anticipating or experiencing aging. Data from the sample were examined to produce a model of resources empirically associated with positive outcomes in aging. Emotional support was found to be positively related to the outcomes of life satisfaction, adjustment to disability and the absence of depressive symptomatology. Further, health concerns, financial security and instrumental support were also related to specific outcomes. These findings send a clear message to rehabilitation and community service providers to be watchful of survivors with limited social support, concerns about their health and an apparent lack of financial resources. The findings underline the need for better access to health services, and improved knowledge and attitudes of community health care providers working with older disabled individuals.

Developing community mental health services: an evaluation of Glasgow's mental health resource centres.

Greater Glasgow Health Board's strategy for the development of community mental health services includes the establishment, over a 7-year period, of multi-disciplinary community mental health resource centres throughout Glasgow. An evaluation of the first phase of the development was carried out in three resource centres. This focused on three key themes: the establishment of multi-disciplinary teams, targeting of those with the most severe illnesses and the participation of users in the care process. The evaluation exercise comprised five substantive elements: analysis of the clinical database; interviews with staff within each of those centres, interviews with representatives of key external agencies associated with each centre; a survey of general practitioners; and a survey of the views of clients, their carers, their key workers, and their general practitioners (GPs). Clients were generally very satisfied with the services and felt that the resource centres met all their mental health needs. Although the majority of current centre cases had severe mental illnesses and those with the more severe conditions had the highest contact rates there was evidence that in the absence of a clear framework for referral the centres were also providing services for those with less severe illnesses. Despite a wish by centre staff to move towards modes of working less dominated by health professionals and more inclusive of other resources and especially of clients themselves, these goals remained to be achieved: there was a lack of clarity in the definition of the appropriate target groups for the centres; access to crisis support was regarded as problematic; the concept of multi-disciplinary team working had yet to be fully realized with evidence suggesting that some psychiatrists working in the resource centres had not embraced many aspects of the new approach to service delivery including a focus on the severely ill; and progress towards the ideal of active client involvement had been slow.

Allocating resources for health and social care: the significance of rurality.

Whilst an allowance is made for sparsity in the allocation of resources for social care services in England, rurality is not a significant factor in health resource allocation. This lack of consistency in resource allocation criteria has become increasingly visible as health and social services departments are required to work in partnership across a range of areas. Differences in funding mechanisms also raise the question of why it is legitimate to make adjustments for rurality in the distribution of some public services, but not for others. Against this background, the present paper considers the case for a rural premium in health resource allocation which, it proposes, can be made on four grounds. First, there is evidence that the current National Health Service (NHS) formula introduces systematic biases in favour of urban areas in the way in which it expresses 'need' for healthcare. Secondly, the way in which the current system compensates for unavoidable variations in the costs of providing services takes insufficient account of the additional costs associated with rural service provision. Thirdly, with a growing emphasis on the need to attain national quality standards, rural primary care trusts and social services departments can no longer tolerate lower levels of services. Finally, a case for a rural premium can be made on the basis of precedent. England is the only country in the UK that does not make a major adjustment for rurality in its NHS formula. The paper concludes that the English NHS resource allocation system has done little to counter marked service deprivation in rural areas. Given evidence that rural local authorities also spend less on social care services and direct provision, this raises serious questions about the extent to which the needs of vulnerable people in English rural areas are being adequately served.

Confirmation of the role of the Mayo Risk Score as a predictor of resource utilization after orthotopic liver transplantation for primary biliary cirrhosis.

Resource utilization is an important consideration when patients are selected for orthotopic liver transplantation (OLT). The Mayo Risk Score has been proposed to help predict optimum time for OLT. We assessed the relation between Mayo risk score, Child-Pugh score, and resource utilization and outcome after OLT for primary biliary cirrhosis. The mean Mayo risk score was greater in patients who died than in the survivors (8.6 +/- 1.4 v 7.1 +/- 1.8; P <.05). There was a positive correlation between Mayo risk score and the 4 resource variables studied (intraoperative blood requirements, time ventilated, and duration of intensive care unit and hospital stays). Patients with a Mayo risk score greater than 7.8 used almost twice the resources of patients with a risk score less than 7.8. A positive correlation also existed between Child-Pugh score and duration of hospital stay. The mean Child-Pugh score in patients who died was greater than that in survivors (10.7 +/- 2.0 v 8.5 +/- 2.8, P =.03). This study confirms that Mayo Risk score is an important predictor of resource utilization and outcome after OLT.

Human resource management in hospitals: a contested arena for jurisdiction.

During the past 10 years, financial pressures on health service providers have led to a quest for more efficient service delivery and many consequential changes to the organisation and utilisation of staff. This study investigated the organisational responses to such pressures by four major South Australian hospitals and the level of involvement of hospital human resource staff in the staffing issues associated with strategic planning. With one exception, there was little contribution from qualified human resource professionals to staffing decisions involving medical and nursing personnel and little value was placed on their potential input by other professional groups. If, as suggested by writers on strategic human resource management, human resource practice is moving toward a more strategic approach, then there is a large credibility gap for human resource staff to overcome within the South Australian health service.

A reagent resource to identify proteins and peptides of interest for the cancer community: a workshop report.

On the basis of discussions with representatives from all sectors of the cancer research community, the National Cancer Institute (NCI) recognizes the immense opportunities to apply proteomics technologies to further cancer research. Validated and well characterized affinity capture reagents (e.g. antibodies, aptamers, and affibodies) will play a key role in proteomics research platforms for the prevention, early detection, treatment, and monitoring of cancer. To discuss ways to develop new resources and optimize current opportunities in this area, the NCI convened the "Proteomic Technologies Reagents Resource Workshop" in Chicago, IL on December 12-13, 2005. The workshop brought together leading scientists in proteomics research to discuss model systems for evaluating and delivering resources for reagents to support MS and affinity capture platforms. Speakers discussed issues and identified action items related to an overall vision for and proposed models for a shared proteomics reagents resource, applications of affinity capture methods in cancer research, quality control and validation of affinity capture reagents, considerations for target selection, and construction of a reagents database. The meeting also featured presentations and discussion from leading private sector investigators on state-of-the-art technologies and capabilities to meet the user community's needs. This workshop was developed as a component of the NCI's Clinical Proteomics Technologies Initiative for Cancer, a coordinated initiative that includes the establishment of reagent resources for the scientific community. This workshop report explores various approaches to develop a framework that will most effectively fulfill the needs of the NCI and the cancer research community.

A web-based teaching resource to prepare for final undergraduate examination: a French pilot study.

Access to accurate and quality-controlled health information on the Internet for medical students is not an easy task. CISMeF is the search tool of a MeSH-indexed directory of medical Internet resources in French. Since 2004, a new French Pre-Residency Examination (PRE) is compulsory for all medical students in the 6th year of the curriculum. The goal of this study is to evaluate CISMeF as a tool to provide teaching resources available on the Internet covering PRE material. The CISMeF terminology and the PRE CISMeF module are described. To assess the CISMeF performance in covering PRE program, its precision (number of relevant resources/number of overall resources extracted by CISMeF) and coverage (number of PRE questions covered by at least one resource in the CISMeF gateway) were computed. The CISMeF module for the new French Pre-Residency Examination is efficient as it already covers 95.7% of the program with a precision of 82.2%. Our data demonstrates that CISMeF is acceptable to guide students' learning and should be a useful teaching resource for the preparation of the French Pre-Residency Examination.

Relationships of family functioning, self-esteem, and resourceful coping of Thai adolescents with asthma.

Within the context of Rosenbaum's theory of learned resourcefulness, this correlational study examined the relationships among family functioning, self-esteem, and resourceful coping in Thai adolescents with asthma. A convenience sample of 132 Thai adolescents (aged 12-17 years) with asthma was recruited from the outpatient asthma clinics of four hospitals in Bangkok. Self-administered questionnaires included an assessment of demographic information and asthma status, the revised Family APGAR, the Rosenberg Self-Esteem Scale, and the Children's Self-Control Scale. Hierarchical multiple regression analysis was used to examine the relationships among variables. Effective family functioning had a significant positive effect on self-esteem (beta = .27, p < .01) and resourceful coping (beta = .30, p < .01), controlling for gender and age. However, self-esteem was not significantly correlated with resourceful coping (beta = .15, p = .08). The findings suggest that nursing interventions should take into account the role of family functioning in promoting self-esteem and resourceful coping in Thai adolescents with asthma. Recommendations for future research include replication of the study with a larger sample of adolescents with asthma and with adolescents with other chronic illnesses.

The association of campus resources for gay, lesbian, and bisexual students with college students' condom use.

The author and colleagues examined campus resources for gay, lesbian, and bisexual (GLB) students at 119 US colleges to determine how the presence of such resources affected sexually active students' condom use. A random sample of unmarried, sexually active college students surveyed in 1999 completed questionnaires. Condom use was compared across schools with different levels of GLB resources. Condom use rates, analyzed by sex and sex-partner groups, ranged from 32% to 52%. With additional college variables controlled for, GLB resources were positively associated with the proportion of sexually active students who used condoms (p < .001). This association existed primarily for students with only opposite-sex partners. The author's findings suggest that campus resources for GLB students may be associated with college students' condom use.

Field triage, and the fragile supply of "optimal resources" for the care of the injured patient.

Conventional field triage schemes, including those discussed in this series of reports, assume a high degree of consistency in the availability of resources at designated receiving hospitals. In an organized trauma system, designated trauma receiving facilities of all levels are typically required to maintain a high level of consistency in terms of available facility and human resources for the care of the injured patient. These resources, both facility and provider, are becoming increasingly vulnerable to gaps in availability, however, for a variety of reasons. When gaps in resource availability do occur, their often unpredictable nature nullifies the effectiveness of any established triage protocol, may result in trauma center closures or downgrades, and undermines the entire system of care. It may be necessary in some regions to develop more flexible triage processes, creating a time-sensitive responsiveness to fluctuations in resource availability in a way that dynamically minimizes overtriage and undertriage.

Study design in qualitative research--1: Developing questions and assessing resource needs.

This is the second in a series of four papers on understanding and doing qualitative research [Frankel & Devers (2000) Qualitative research: a consumer's guide, Education for Health, 13, 113-123; Devers & Frankel (2000) Study design in qualitative research--2: sampling and data collection strategies, Education for Health, 13, 263-271]. Here, we focus on problems of study design, including question development, literature review, identifying a target audience and resource needs assessment. We provide a step-by-step description of major issues and choice points in the process. There are three key differences between qualitative and quantitative research designs. First, the logic of qualitative research is often inductive, rather than deductive, and consists of describing people's and groups' particular situations, meanings and experiences. Second, qualitative research designs are often emergent and flexible, and the research itself is quite dynamic. Third, the qualitative research process is non-linear and non-sequential. There is agreement that good qualitative studies answer clearly stated, important research questions. How qualitative research questions are formulated has implications for conducting a literature review. Some scholars believe that literature should be reviewed prior to beginning a study; others argue that this may impede the researcher from truly listening, observing and remaining open to new concepts and ideas. We offer suggestions about formulating research questions and how and when to conduct a literature review. Another important issue in conducting qualitative research is determining the resources that will be needed to conduct a study. These include internal resources, such as research skills, and external resources, such as personnel (expertise and time), equipment, supplies and travel. A description of typical resource and management issues in conducting a qualitative research study is included.

Density dependence, territoriality, and divisibility of resources: from optimality models to population processes.

Species differ enormously in their territorial systems. Some species defend only small areas surrounded by undefended space, while others defend large contiguous territories. Using an optimization approach, we show that this variation can be explained from the density of two types of resources: divisible and nondivisible. We assume that benefits of territories are monotonously related to the defended amount of divisible resources (hereafter called food). In contrast, no benefits are obtained without a nondivisible resource (hereafter called nest site) in the territory, while more than one nest site does not further increase the benefits. The optimal territory size depends on the relative abundance of these resources. With a low density of nest sites, the optimal territory size is small and includes only the nest site. If the density of nest sites is relatively large, the optimal territory size is high, and territories are contiguous. Competition for these different resources yields contrasting patterns of how populations are regulated. If there is mainly competition for nest sites, we expect density-dependent exclusion through territoriality and no density-dependent reproduction. When competition is mainly for food, we expect density-dependent reproduction because optimal territory size will be compressed at higher densities, resulting in lower reproductive success. These predicted patterns indeed are observed in some well-studied passerine species for which both the territorial system and the occurrence of density dependence is known.

Spatial scaling of consumer-resource interactions in advection-dominated systems.

Ecologists studying consumer-resource interactions in advection-dominated systems such as streams and rivers frequently seek to link the results of small-scale experiments with larger-scale patterns of distribution and abundance. Accomplishing this goal requires determining the characteristic scale, termed the response length, at which there is a shift from local dynamics dominated by advective dispersal to larger-scale dynamics dominated by births and deaths. Here, we model the dynamics of consumer-resource systems in a spatially variable, advective environment and show how consumer-resource interactions alter the response length relative to its single-species value. For one case involving a grazer that emigrates in response to high predator density, we quantify the changes using published data from small-scale experiments on aquatic invertebrates. Using Fourier analysis, we describe the responses of advection-dominated consumer-resource systems to spatially extended environmental variability in a way that involves explicit consideration of the response length. The patterns we derive for different consumer-resource systems exhibit important similarities in how component populations respond to spatial environmental variability affecting dispersal as opposed to demographic parameters.

Predicting resource partitioning and community organization of filter-feeding dabbling ducks from functional morphology.

Resource partitioning due to interspecific differences in phenotype is a key component of ecological and evolutionary theory, but the relationship between morphology and resource use is poorly understood for most species. In addition, ecologists often assume that morphological differences cause distinct resource preferences between species. Using mechanistic models that combine bill morphology and kinetics, I show that filter-feeding dabbling ducks face a morphology-mediated trade-off between particle size selection and water filtration rate. When detritus is absent, mallards (Anas platyrhynchos) and northern shovelers (Anas clypeata) should maximize their intake rates and exhibit high overlap in prey size. When prey and detritus co-occur, species should separate prey from detritus by size, leading to reduced intake rates and size-based prey partitioning. Models for both species correctly predicted variation in water filtration rates, particle retention probabilities, and prey ingestion rates due to variation in prey size, the presence of detritus, and experimental modification of bill morphology. Because species have both shared and distinct resource preferences, duck communities should exhibit strong density-dependent niche shifts (i.e., centrifugal dynamics), a finding that contradicts previous studies that assumed that ducks have distinct resource preferences only. Centrifugal dynamics may be widespread among filter feeders because of the common cost of separating prey from detritus.
