Sampling Effectiveness

AbstractNon-bee insects are important for pollination, yet few studies have assessed the effectiveness of sampling these taxa using low cost passive techniques, such as coloured vane traps, among different habitat types.This study sampled 192 sites—108 in wooded and 84 in open habitats within an agricultural region of southern Australia. Pairs of blue and yellow vane traps were placed at each site for a period of seven days during the austral spring.Overall, 3114 flies (Diptera) from 19 families and 528 wasps (non-bee and non-formicid Hymenoptera) from 16 families were collected during the study. This sampling was representative of the region, with vane traps equally or more likely to collect as many families from both taxa as those reported on the Atlas of Living Australia (ALA) database for the sampling area.Blue vane taps (BVTs) had greater average richness of both flies and wasps and greater abundance of individuals than yellow vane traps (YVTs). BVTs were particularly favoured by certain fly and wasp families known to pollinate flowers (e.g. Syrphidae, Bombyliidae and Scoliidae), whilst YVTs sampled some less common fly families, such as Acroceridae and Bibionidae that also provide additional ecosystem services to pollination.Vane traps are an effective passive sampling technique for non-bee pollinators, such as flies and wasps. This study supports the use of vane traps as a component of the sampling protocol for ecological census and population monitoring within multiple habitat types, to effectively sample a more complete pollinator community.

The Impact

In the context of global biodiversity loss, wildlife population monitoring is a major challenge. Some innovative techniques such as the use of drones—also called unmanned aerial vehicle/system (UAV/UAS)—offer promising opportunities. The potential of UAS-based wildlife census using high-resolution imagery is now well established for terrestrial mammals or birds that can be seen on images. Nevertheless, the ability of UASs to detect non-conspicuous species, such as small birds below the forest canopy, remains an open question. This issue can be solved with bioacoustics for acoustically active species such as bats and birds. In this context, UASs represent an interesting solution that could be deployed on a larger scale, at lower risk for the operator, and over hard-to-reach locations, such as forest canopies or complex topographies, when compared with traditional protocols (fixed location recorders placed or handled by human operators). In this context, this study proposes a methodological framework to assess the potential of UASs in bioacoustic surveys for birds and bats, using low-cost audible and ultrasound recorders mounted on a low-cost quadcopter UAS (DJI Phantom 3 Pro). The proposed methodological workflow can be straightforwardly replicated in other contexts to test the impact of other UAS bioacoustic recording platforms in relation to the targeted species and the specific UAS design. This protocol allows one to evaluate the sensitivity of UAS approaches through the estimate of the effective detection radius for the different species investigated at several flight heights. The results of this study suggest a strong potential for the bioacoustic monitoring of birds but are more contrasted for bat recordings, mainly due to quadcopter noise (i.e., electronic speed controller (ESC) noise) but also, in a certain manner, to the experimental design (use of a directional speaker with limited call intensity). Technical developments, such as the use of a winch to safely extent the distance between the UAS and the recorder during UAS sound recordings or the development of an innovative platform, such as a plane–blimp hybrid UAS, should make it possible to solve these issues.

Short-term debt is regarded as an important source of financing for Small and Medium-sized enterprises (SMEs). This is because it can be easily accessed and useful during times of emergent working capital shortage. However, short-term debt is the least researched among the components of capital structure, which explains why its contribution to the financial performance of small and medium-sized businesses still lacks empirical validation especially in the Ugandan context. This paper sought to determine the effect of short-term debt on financial performance of Small and Medium Enterprises in Uganda. The study adopted a descriptive cross-sectional research design to collect and analyse the data. Stratified random sampling technique was used to select SMEs while purposive sampling technique was used to select one key respondent from each of the sampled 453 SMEs in Uganda. Primary data was collected using survey questionnaire. Data was analysed using descriptive statistics and simple linear regression analysis. The findings indicted that short-term debt had a negative and significant effect on financial performance of SMEs as measured by return on assets. The study provides empirical evidence to support the propositions in the extant literature that short-term debt significantly hampers financial performance of SMEs. The study recommends that SMEs should adopt low cost operation procedures to improve profitability. This would lead to accumulated profits that can be used for investment purposes as a means of driving growth among the SMEs without resorting to borrowing. This paper suggests that further research should be conducted to establish the justification for the negative and significant effect of short-term debt on financial performance using qualitative approaches.

Today, in many countries of the world, there is a steady increase in public spending related to health. One of the promising options for optimizing these costs is the widespread use of telemedicine as a method of remote medical care. It is known that the main contribution to the health of an individual and the population as a whole is made by lifestyle. Effective screening, timely detection of risk factors and diseases at the early stages of their development, medical examinations, universal opening of health centers, prevention offices, health schools – all these measures are aimed at increasing the duration and quality of life of the nation. Despite the availability and relatively low cost of well-known programs for remote screening, it is impossible not to mention their significant disadvantages: the lack of final analytical documents, the coverage of one or more systems, the need for a face-to-face visit to the doctor to calculate risks and determine further patient management tactics. The article proposes a methodology for telemedicine screening of adult health in outpatient settings using a system for analyzing unstructured data for population monitoring of chronic non-communicable diseases. The development is based on risk calculation using the method of “decision rules” as a means of description used in the theory of fuzzy sets. The result of the method developed by the authors is a variant of telemedicine questionnaire screening, which allows determining health risks by specific profiles, forming a final conclusion with recommendations for a healthy lifestyle, further examination, treatment and prevention of chronic diseases. The development can be used in public and private medical institutions. Of particular interest is the possibility of integrating software into medical practice in the current conditions of the pandemic, as well as in the state projects “Lean polyclinic”, “Arctic doctor” and “Zemsky doctor”.

IntroductionClinicians often struggle to recognise whether palliative care patients are imminently dying.1 2 A previous study identified the factors that expert palliative care doctors (with demonstrated prognostic skills) had used to judge the probability of patients dying within 72 hours.Aim and methodsTo evaluate whether an online training resource can teach medical students to formulate survival estimates for palliative care patients that are more similar to experts’ estimates. In this online randomised controlled trial we will recruit 128 students in the penultimate/final year of medical school. Participants are asked to review three series of vignettes describing patients referred to palliative care and provide estimates (0%–100%) about the probability that patients will die within 72 hours. After the first series of vignettes students in the intervention arm are given access to the training resource showing how experts weighted the various symptoms/signs. Participants are asked to complete a second series of vignettes and then a third series after two weeks to assess if any effect has been maintained.ResultsStudents’ survival estimates will be correlated with experts’ estimates to determine the baseline level of agreement and any changes following the intervention. The primary outcome will be the survival estimates provided in the second series of vignettes. Secondary outcomes include the estimates provided at the follow-up the weighting of symptoms/signs and levels of discrimination and consistency.ConclusionThis study will provide evidence about whether a brief low-cost online training resource can influence how medical students make prognostic decisions in an experimental setting.References.

Malaysian government has introduce public low-cost housing during Malaysian Plan as an initiative to help the low-income household owners and squatters. However, in developing the low-cost housing, the quality and environmental aspects should be emphasized. Post Occupancy Evaluation (POE) is an approach in assessing existing building performance and future development of buildings to ascertain feedback from occupants after the building has been occupied for some time. This paper determines the physical environment based on occupants preference by using the POE tools. Physical environment elements obtained through literature review consists of facilities, spaces and services offered in each housing unit. A sum of 13 physical environment elements were measured by 868 occupants in Johor’s Public Low-cost Housing. Convenience sampling technique was the method used to determine the adequacy of sample throughout data collection process, subsequently it has been analyzed using frequency and factor statistics. The study reveals that physical environment elements were playing the crucial role in every housing unit. However, dwelling unit features, housing conditions and location were mainly the highest preference amongst occupants. In fact, physical environment elements plays an entirely crucial role in developing occupant’s comfort and satisfaction. Nevertheless, a few physical elements that show the least preferable amongst occupant such as external utilities and services, management, lighting and ventilation need to be given more attention in order to create a better environment in the future.

Bereavement Care

ABSTRACT Perinatal bereavement is a unique mourning situation, as the parent's expectation and joy at the prospect of a new life change into a despair and grief. IUFD may represent a significant loss of the mother's perception of her body's functional adequacy associated with body image and feelings of self-wroth. Objectives To assess the knowledge and identify attitude regarding perinatal bereavement care among nurses. To find the correlation between knowledge and attitude among the nurses regarding perinatal bereavement care. Methods The research approach for the study was descriptive survey. The sample size considered for the study was 30 registered nurses working in maternity and NICU. The sampling technique used for the study was purposive. The tool used for gathering relevant data was a structured knowledge questionnaire. Results The results revealed that majority of the nurses 23(76.6%) belonged to a age group of 21-23 years. Majority 17(56.6%) of the nurses had experience of less than one year in maternity unit and NICU. Maximum nurses 25(83.3%) had no previous experience in managing perinatal bereavement. None of the nurses 30(100%) had attended any in service education. Majority 15(50%) of nurses had poor knowledge about the concept of perinatal bereavement. Maximum 13(43%) of the nurses had average knowledge of perinatal bereavement care, while minimum 5 (16.6%) had fair knowledge of the specified area. Half 15(50%) of the nurses possessed a positive attitude towards perinatal bereavement care. There is no correlation between knowledge and attitude of nurses with regards to perinatal bereavement care. Conclusion In order to facilitate a normal grieving process among bereaved families, the nurse should be equipped with adequate knowledge, a positive attitude and skill in rendering such care.

Natural isotopic labelling of animal metabolic processes presents great advantages over the use of artificially enriched compounds. These advantages include the use of natural diets, low cost and easiness of handling, sampling and disposal. Changes in the 13C/12C ratio of expired CO2 after ingestion of a test meal containing a variable proportion of C3 and/or C4 plant-derived products permits measurements of the immediate oxidation of dietary carbohydrates. A breathing device for collection of expired CO2 and purification techniques are described. The breath-sampling device is composed of a polypropylene enclosure and a rubber bag. The rubber bag is blown up by the animal and a sample of the expired gas is transferred to a sampling glass holder in which a vacuum had been previously achieved. Sample purification of expired CO2 is done by differential freezing. Key words: Breath device, carbon 13, calf
