Here, we experimentally tested this hypothesis by providing wild passerine birds supplemental food （on a raised feeding platform） at either 1 or 4 m from the edge of forest cover （potential refuge）, in either the presence or absence of a nearby simulated predation threat （a sharp-shinned hawk Accipiter striatus model）. Compared with the control treatment, we observed proportionally fewer bird visits to the food patch, and the birds took longer to re-emerge from forest refuge and return to feed at the food patch, after the hawk presentation than before it. The observed threat-sensitive latency-to-return response was stronger when the food patch was further away from the nearest refuge. Overall, our results are consistent with the predictions of the threat-sensitive predator avoidance hypothesis in that wild passerine birds （primarily black-capped chickadees Poecile atricapillus） exhibited more intense antipre- dator behavioural responses with increasing level of apparent threat. The birds were thus sensitive to their local perceived threat of predation and traded-off safety from predation （by refuging） and foraging gains in open habitat in a graded, threat-sensitive manner [Current Zoology 60 （6）： 719-728, 2014].展开更多

Methods: A quasiexperimental, longitudinal and prospective study, held from October 25 2010 to April 11, 2011 at a hospital in San Luis Potosi, Mexico. To select groups applied a non-probabilistic convenience sampling that was composed of 28 people, 15 for the study group and 13 to the control group. The study group received training that was divided into three phases in which assessed the knowledge and skills taking the smear, the control group received conventional training offered by your workplace. Papanicolaou quality was measured before and after the intervention. The reference used international classification system Bethesda 2001. For data analysis we used the Student t test. Results: The study group increased knowledge (t = 8.768, p = 0.000) in the management of official standards, in the anatomy of the lower female genital tract and in the form of testing. Technical skills (t = 8.639, p = 0.000) also increased in the study group after the intervention. The control group showed no significant changes. The quality report of the samples in the study group increased from 60% to 86.7% and in the control group decreased from 92.3% to 84.6%. Conclusions: The training is effective in improving the knowledge and skills in taking Pap. Health staff who received the training improved their performance and showed more interest in providing high quality service to women.展开更多

Thus, the objectives of this study were to determine: 1) if FMH is regularly acquired in a representative primary care practice (the Queen’s Family Health Team, QFHT);2) what is included in the FMH obtained;3) what the utility of FMH is with regards to patient management in primary care;and 4) to utilize healthcare practitioners’ perspectives in order to elucidate any findings regarding the acquisition and utility of FMH at the QFHT. Methods: Patients were interviewed in order to obtain their FMH. For each patient, the FMH obtained was compared to the FMH documented in the patient’s record to determine the record’s completeness. Each patient’s FMH was analyzed for significant history of coronary artery disease (CAD), diabetes mellitus type II (DMII), substance abuse (SA) and colorectal cancer (CRC). Participants were patients scheduled for appointments at the QFHT between May and July 2011. Any patient of the QFHT older than 25 years was eligible to participate. Clinical staff of the QFHT completed an online questionnaire to determine healthcare practitioners’ perspectives regarding the acquisition and utility of FMH. Results: 83 patients participated in the study. Participants ranged in age from 25 - 86 years (median: 63 years);69% were female. FMH present in patients’ records was often either incomplete (42% of charts reviewed) or not documented at all (51% of charts reviewed). Knowledge of FMH can affect patient management in primary care for the diseases assessed (CAD, DMII, SA and CRC). HCP do consider FMH to be important in clinical practice and 86% of respondents stated that they regularly inquired about patients’ FMH. Interpretation: Despite the belief by HCP that FMH is important, there is a disparity between this belief and their practices regarding its documentation and utilization. Finally, analysis of the FMH of the representative population studied shows that information commonly missing in patients’ FMH can affect patient management at a primary care level.展开更多

This study examined the factors influencing the behavior of taking medicine in elderly patients undergoing HD. Subjects and Methods: The subjects comprised 70 outpatients > 65 years undergoing HD (48 male and 22 female). The mean age of the patients was 72.5 ± 4.4 years. The mean duration of dialysis history was 6.1 ± 5.2 years. We performed a questionnaire survey using Medication Assessment Tool, The Kidney Disease Quality of Life (QOL)-Short Form and Acceptance for Dialysis Instrument. Result: Two factors related to poor behavior of taking medicine: dialysis history < 2 years and poor acceptance of dialysis. The multiple regression analysis showed patient satisfaction (β = –0.329, p < 0.01) and symptoms/problems (β = –0.273, p<0.05) as significant independent variables relating to behavior of taking medicine. Conclusion: Poor behavior of taking medicine is related to a short dialysis period, poor acceptance and poor satisfaction of dialysis therapy in elderly patients.展开更多

文摘No property may be taken for public use without just compensation.The issue is what is“just compensation”and how it is determined in a particular circumstance.Regardless of the type of valuation,the Greek Constitution(Article 17,paragraphs 2-5)clearly forbids estimation based on possible future projections.In this way,future externalities,positive or negative,deriving from the change of use are not incorporated.This contravenes the Pareto optimal resource distribution and even challenges the Caldor-Hicks compensation criterion,especially in cases of partial takings.We suggest valuation to include a best-case and a worst-case scenario for possible future values.A combination of them,e.g.,the average,will be used to determine benefits and costs and the final level of compensation.The most important externality under consideration,especially in cases of land properties condemned for public large-scale constructions,such as environmental public utilities,should be the environmental effect.The internalisation of possible negative externalities should be internalised by the construction benefactor.
