Improving precision and reducing bias in biological surveys: estimating false-negative error rates

The use of presence/absence data in wildlife management and biological surveys is widespread. There is a growing interest in quantifying the sources of error associated with these data. We show that false-negative errors (failure to record a species when in fact it is present) can have a significant impact on statistical estimation of habitat models using simulated data. Then we introduce an extension of logistic modeling, the zero-inflated binomial (ZIB) model that permits the estimation of the rate of false-negative errors and the correction of estimates of the probability of occurrence for false-negative errors by using repeated. visits to the same site. Our simulations show that even relatively low rates of false negatives bias statistical estimates of habitat effects. The method with three repeated visits eliminates the bias, but estimates are relatively imprecise. Six repeated visits improve precision of estimates to levels comparable to that achieved with conventional statistics in the absence of false-negative errors In general, when error rates are less than or equal to50% greater efficiency is gained by adding more sites, whereas when error rates are >50% it is better to increase the number of repeated visits. We highlight the flexibility of the method with three case studies, clearly demonstrating the effect of false-negative errors for a range of commonly used survey methods.

Gastrointestinal transit in the common brushtail possum measured by gamma scintigraphy

This paper reports an example of the application of pharmaceutical technology to wildlife management, specifically the design of an oral delivery system for the common brushtail possum in New Zealand. Designing an oral delivery system requires a knowledge of the time taken for particulates to reach target sites within the gastrointestinal tract (GIT). The transit time for fluid and indigestible particles of two different size ranges was determined in the common brushtail possum (Trichosurus vulpecula). Technetium-labelled (Tc-99m) anion exchange resin particles (75-125 or 500-700 mu m diameter) or solution (Tc-99m-labelled diethylenetriamine pentaacetic acid, Tc-99m-DTPA) was administered orally. At predetermined times after dosing (3, 6, 12, 24 or 32 h), the distribution of radioactivity throughout excised gastrointestinal tracts was determined by gamma scintigraphy. The transit profile was similar for the three formulations investigated. Unlike other closely related hindgut fermenting marsupials, there was no evidence to support the presence of a colonic separating mechanism in the common brushtail possum. Gastrointestinal transit was independent of body mass, gender and time of day that the dose is given. To target the hindgut for oral delivery of protein and peptide biocontrol agents, the formulation Would need to protect the bioactive for approximately 12 h prior to release. (c) 2005 Elsevier B.V.

Factors affecting the vigilance and flight behaviour of impalas

This study investigated the influences of various natural and anthropogenic factors on the vigilance and flight behaviour of impalas in the Save Valley Conservancy, Zimbabwe, using multivariate statistical techniques. The factor that most significantly affected the proportions of time that individuals spent being vigilant and their rates of vigilance was the position of a focal animal in the group; impalas on the periphery of a group were more vigilant than central impalas. Both measures of vigilance were also negatively related to group size. Males spent more total time being vigilant but females raised their heads more often. Impalas spent more time being vigilant in the late afternoon than in the early morning, when greater than ten metres from cover, and when predators had been nearby within the previous six hours. Impalas spent more time vigilant at the property where more impalas were hunted, possibly reflecting the differences in the intensity of hunting by humans on the two properties. Flight distances at the approach of humans were significantly greater at one property than the other, and were also greater for small groups. Further research into the effects of hunting by humans on animals' antipredator behaviours would provide valuable insights for wildlife managers.

Optimizing Presence–Absence Surveys For Detecting Population Trends

Presence-absence surveys are a commonly used method for monitoring broad-scale changes in wildlife distributions. However, the lack of power of these surveys for detecting population trends is problematic for their application in wildlife management. Options for improving power include increasing the sampling effort or arbitrarily relaxing the type I error rate. We present an alternative, whereby targeted sampling of particular habitats in the landscape using information from a habitat model increases power. The advantage of this approach is that it does not require a trade-off with either cost or the Pr(type I error) to achieve greater power. We use a demographic model of koala (Phascolarctos cinereus) population dynamics and simulations of the monitoring process to estimate the power to detect a trend in occupancy for a range of strategies, thereby demonstrating that targeting particular habitat qualities can improve power substantially. If the objective is to detect a decline in occupancy, the optimal strategy is to sample high-quality habitats. Alternatively, if the objective is to detect an increase in occupancy, the optimal strategy is to sample intermediate-quality habitats. The strategies with the highest power remained the same under a range of parameter assumptions, although observation error had a strong influence on the optimal strategy. Our approach specifically applies to monitoring for detecting long-term trends in occupancy or abundance. This is a common and important monitoring objective for wildlife managers, and we provide guidelines for more effectively achieving it.

Evidence of Recent Phosphorus Enrichment in Surface Soils of Taylor Slough and Northeast Everglades National Park

Everglades National Park (ENP) is the last hydrologic unit in the series of impounded marsh units that make up the present-day Everglades. The ENP receives water from upstream Water Conservation Areas via canals and water control structures that are highly regulated for flood control, water supply, wildlife management, concerns about poor water quality and the potential for downstream ecosystem degradation. Recent surveys of surface soils in ENP, designed for random sampling for spatial analysis of soil nutrients, did not sample proximate to inflow structures and thus did not detect increased soil phosphorus associated with these water conveyances. This study specifically addressed these areas in a focused sampling effort at three key inflow points in northeast ENP which revealed elevated soil TP proximate to inflows. Two transects extending down Shark River Slough and one down Taylor Slough (a natural watershed of particular ecological value) were found to have soil TP levels in excess of 500 mg kg−1—a threshold above which P enrichment is indicated. These findings suggest the negative impact of elevated water (P) from surface flows and support the assertion that significant soil TP enrichment is occurring in Taylor Slough and other areas of northeastern ENP.

Metodologia para gerenciamento de projetos em tecnologia da informação baseada no guia PMBOK: um estudo de caso na Secretaria de Estado da Saúde Pública do Rio Grande do Norte

Nowadays the search for growth makes organizations seeking competitive advantages, project management shares this goal, through techniques that assist in the search for an improved management of the various fields of knowledge through a design methodology. The world is driven by projects and the search for ways to better manage activities such as time, cost and term towards the success of a particular project is something constant. A major contribution that IT can make to the health sector is the support for the management area. IT can integrate processes, optimize the interconnection between the various sectors, make hospitals have access to inside information of good quality, as well as support in the healthcare area, sharing pictures, uniting the various aspects of nursing and nursing service. The major challenge faced by the SESAP Information Technology sector at present is in project management in IT , which does not exist makes investments in the area are increasingly difficult due to this deficiency in management develop their own systems without cost additional to the State. This study seeks to build and strengthen the Project Management within the Department of Health through the implementation of a project office that will manage the final result of this work methodology based on PMBOK, and still show the functionality applied to development the state Hospital Management System that will later be installed on all Regional Health Units and proposing measures for the sustainability and development of the sector amid the difficulties of the current public service. Such action will result in a savings of more than R$ 107,000.00 (one hundred seven thousand) regarding spending private software currently used by the assignment of invested by the State of Rio Grande do Norte user licenses, representing more than 5 % of the total budget of the State Department of Public Health of the State

Da voz que cala ao corpo que fala: o assédio moral no ambiente de trabalho como desafio para o serviço social

The changes ocurred in the world of capitalist labor, especially from the last decades of the 20th century, accentuated the process of manipulation and domination of the working class, materialized mainly through naturalization and / or trivialization of violence, conducted in the work environment. From this process, emerge the elements of bullying, that is, the embarrassing and humiliating practices which extend through time, degrading human race, and becoming fruitful object for study, debate and the intervention of the professionals of the Social Service area. Thus, we assume the perspective of analyzing the concepts and the work of social workers, whom work at people management area before the bullying in the workplace. We propose the following objectives: apprehend the settings of bullying, in the contemporary context of competitiveness and flexibility of work, as well as its implications for workers' health; characterize the background of this expression of violence at work in the municipality of Natal- RN; and analyze the powers and duties of the social worker in the process of prevention, identification and addressing of bullying in the context of work. This study consisted of a qualitative approach, based on the dialectical-critical method as soon as we adopt methodological procedures such as: theoretical knowledge, documental and field research, and performed using semi-structured interviews. The subjects of this research were nine (09) the Social Service professionals working in personnel management area, in five (5) institutions with legal and branches of different activities, located in Natal-RN. Even interviewed one (01) representative of the Public Ministry of Rio Grande do Norte Office (MPT-RN). The findings of this analysis indicate that bullying is a contemporary expression of "social question", which is presented as a demand for the Social-assistants – covered up and / or camuflage – under the guise of problems related to workers' health or mere conflicts of interpersonal relationships, that is, without any causal connection with the organization of work. The fear of losing job, not to be inserted in the labor market, and / or suffering reprisals, deepens the subject levels of the victims of bullying. Hence the importance of Social Workers are capable to understand the social reality, by preventing and combating the elements of bullying.

Freshwater Resource Supply Modeling for Developed and Undeveloped Watersheds

Globally, the current state of freshwater resource management is insufficient and impeding the chance at a sustainable future. Human interference within the natural hydrologic cycle is becoming dangerously irreversible and the need to redefine resource managerial approaches is imminent. This research involves the development of a coupled natural-human freshwater resource supply model using a System Dynamics approach. The model was applied to two case studies, Somalia, Africa and the Phoenix Active Management Area in Arizona, USA. It is suggested that System Dynamic modeling would be an invaluable tool for achieving sustainable freshwater resource management in individual watersheds. Through a series of thought experiments, a thorough understanding of the systems’ dynamic behaviors is obtainable for freshwater resource managers and policy-makers to examine various courses of action for alleviating freshwater supply concerns. This thesis reviews the model, its development and an analysis of several thought experiments applied to the case studies.
