The extent to which welfare needs of breeding dogs are met in commercial dog-breeding kennels is a potential point of controversy. This analysis sought to understand US residents’ perceptions and priorities related to dog welfare : by investigating (a) perceptions of breeding-dog welfare needs and (b) perceptions of various nonhuman animal welfare information sources. Using best/worst-choice experiments conducted in an online survey, respondents’ choices for most and least important breeding-dog welfare needs (n = 508) and most/least trusted canine welfare information sources (n = 508) were analyzed. The survey sample was targeted to be representative of the US population in terms of gender, age, region of residence, income, and education. The largest preference shares (relatively most important) for breeding-dog welfare needs were for “availability of food and water” (39.2%) and health/veterinary care (18.1%). The largest preference shares (relatively most trusted sources) for welfare information were American Society for the Prevention of Cruelty to Animals, a veterinarian, and American Veterinary Medical Association, with 25.1%, 16.4%, and 14.1% shares, respectively. 相似文献

Bull breeds are commonly kept as companion animals, but the pit bull terrier is restricted by breed-specific legislation (BSL) in parts of the United States and throughout the United Kingdom. Shelter workers must decide which breed(s) a dog is. This decision may influence the dog's fate, particularly in places with BSL. In this study, shelter workers in the United States and United Kingdom were shown pictures of 20 dogs and were asked what breed each dog was, how they determined each dog's breed, whether each dog was a pit bull, and what they expected the fate of each dog to be. There was much variation in responses both between and within the United States and United Kingdom. UK participants frequently labeled dogs commonly considered by U.S. participants to be pit bulls as Staffordshire bull terriers. UK participants were more likely to say their shelters would euthanize dogs deemed to be pit bulls. Most participants noted using dogs' physical features to determine breed, and 41% affected by BSL indicated they would knowingly mislabel a dog of a restricted breed, presumably to increase the dog's adoption chances. 相似文献

ABSTRACTThe nature of the human–animal bond in contemporary Australian Indigenous communities is little researched, but it is essential to understand this bond in order to develop much needed appropriate animal health and management practices. A semi-structured interview format was used to elicit information on attitudes to dogs in seven Australian Indigenous communities. This explored the importance of dogs to the community and to the individual, and the balance between the positives and negatives of having dogs in the communities, with particular reference to improving dog and community health and welfare. Theme analysis of the semi-structured interview responses (n = 137) revealed a variety of attitudes to dogs within the communities. A strong theme was the importance of dogs at a community level. Many of the reasons given for the importance of dogs in the community were based on traditional cultural values or beliefs. These included dogs being necessary to guard people at night from spirits, and as part of the kin system. Further, the cultural practice of “pay-back” for wrong-doing included wrong-doing directed at dogs in all communities, even the most westernized. Occurring simultaneously with these positive attitudes, the poor health and overpopulation of dogs in the community was acknowledged and the negative effects on people's lives recognized. However, the value of the dogs to the community meant that shooting dogs without consent or poisoning them were not seen as appropriate solutions to overpopulation. Many people were prepared to euthanize some of their dogs (via an overdose of barbiturate) or have them undergo sterilization surgery. Thus, contrary to appearances from a Western perspective, the traditional Indigenous human–dog bond was found to be strong, and thus must be taken into account in developing appropriate and sustainable animal health and management practices. 相似文献

Don't Blame the ‘Bio’ — Blame the ‘Ethics’: Varieties of (bio) ethics and the challenge of pluralism
Charlesworth M 《Journal of bioethical inquiry》2005,2(1):10-17
We tend to think that the difficulties in bioethics spring from the novel and alarming issues that arise due to discoveries in the new biosciences and biotechnologies. But many of the crucial difficulties in bioethics arise from the assumption we make about ethics. This paper offers a brief overview of bioethics, and relates ethical 'principlism' to 'ethical fundamentalism.' It then reviews some alternative approaches that have emerged during the second phase of bioethics and argues for a neo-Aristotelian approach. Misconceptions about ethical principles and ethical reasoning not only distort our views of the business of bioethics, but they also prevent us from facing up to the formidable problems posed by ethical pluralism in so-called liberal societies. 相似文献

Multiple classes of commercially important auxin herbicides have been discovered since the 1940s including the aryloxyacetates (2,4-D, MCPA, dichlorprop, mecoprop, triclopyr, and fluroxypyr), the benzoates (dicamba), the quinoline-2-carboxylates (quinclorac and quinmerac), the pyrimidine-4-carboxylates (aminocyclopyrachlor), and the pyridine-2-carboxylates (picloram, clopyralid, and aminopyralid). In the last 10 years, two novel pyridine-2-carboxylate (or picolinate) herbicides were discovered at Dow AgroSciences. This paper will describe the structure activity relationship study that led to the discovery of the 6-aryl-picolinate herbicides Arylex™ active (2005) and Rinskor™ active (2010). While Arylex was developed primarily for use in cereal crops and Rinskor is still in development primarily for use in rice crops, both herbicides will also be utilized in additional crops. 相似文献

BackgroundEquitable access to basic public health services is a priority in China. However, primary healthcare workers’ competence to deliver public health services is relatively poor because they lack professional training. Since the availability of web-based training has increased in China, the current study explored stakeholders’ perceptions of a web-based training program on basic public health services to understand their thoughts, experiences, and attitudes about it.MethodsSix focus group discussions with primary healthcare workers and three with directors of township hospitals, county-level Health Bureaus, and county-level Centers for Disease Control and Prevention were conducted in Yichang City during 2013. Semi-structured topic guides were used to facilitate qualitative data collection. Audio recordings of the sessions were transcribed verbatim and theme analysis was performed.ResultsMost of the study’s participants, especially the village doctors, had insufficient knowledge of basic public health services. The existing training program for primary healthcare workers consisted of ineffective traditional face-to-face sessions and often posed accessibility problems for the trainees. Most of the study’s participants had a positive attitude about web-based learning and expressed a strong desire to receive this novel training approach because of its flexibility and convenience. The perceived barriers to utilizing the web-based training method included poor computer literacy, lack of personal interaction, inadequate infrastructure, and lack of time and motivation. The facilitators of this approach included the training content applicability, the user-friendly and interactive learning format, and policy support.ConclusionsWeb-based training on basic public health services is a promising option in rural China. The findings of the study will contribute knowledge to implementation of web-based training in similar settings. 相似文献

AbstractWe report the isolation of the genes encoding the β1 and β2 adrenergic receptors from dog genomic DNA. Sequence analysis of both genes revealed intronless open reading frames of 473 and 415 amino acid residues, receptively. Heterologous expression of both receptors in CHO cells indicated that both receptors are functionally similar to the human homologs. Comparing the dog β1 and β2 adrenergic receptors, the β1 receptor appears to bind to G proteins more tightly than the β2 receptor. Heterologously expressed receptors provide a convenient system for evaluating novel receptor agonists and antagonists. 相似文献

Many studies have examined adults’ perceptions of and attitudes toward large carnivores to assess human–wildlife conflict and inform conservation strategies, but there have been few studies concerning children. I studied secondary school students’ perceptions of and attitudes toward brown bears (Ursus arctos) and other large mammals in Turkey via a questionnaire survey. The questionnaire, consisting of 18 questions, was completed by 215 rural and 98 urban secondary school students. Both sets of students liked bears; they were also afraid of them and unsure about living with them in the future. While there were no gender differences in attitudes and perceptions, there were marked differences between urban and rural students. Urban students had less contact with nature, gained more of their knowledge about bears from documentaries, and had less positive attitudes toward bears. They were also more likely to be afraid of species not present in Turkey, for example, anaconda, while rural students were most afraid of wild boars. Factor analysis identified three important themes: familiarity with bears, conservation of bears, and experiencing conflict with bears, which explained 49.8% of the variance in attitudes toward bears. The most important factor for the development of negative attitudes toward bears was personal experience of human–bear conflict, suggesting that measures to reduce human–bear conflict in rural areas may help to sustain students’ positive attitudes toward the conservation of bears. 相似文献

The inhibitory effects of three biguanido-oxovanadium complexes ([VO(L(1-3))(2)]·nH(2)O: HL(1) = metformin, HL(2) = phenformin, HL(3) = moroxydine) against four protein tyrosine phosphatases (PTPs) and an alkaline phosphatase (ALP) were investigated. The complexes display strong inhibition against PTP1B and TCPTP (IC(50), 80-160 nM), a bit weaker inhibition against HePTP (IC(50), 190-410 nM) and SHP-1(IC(50), 0.8-3.3 μM) and much weaker inhibition against ALP (IC(50), 17-35 μM). Complex 3 is about twofold less potent against PTP1B, TCPTP and HePTP than complexes 1 and 2, while complex 2 inhibits SHP-1 more strongly (about three to fourfold) than the other two complexes. These results suggest that the structures of the ligands slightly influence the potency and selectivity against PTPs. The complexes inhibit PTP1B and ALP with a typical competitive type. 相似文献

Background
Almost 50% of Americans have elevated low-density lipoprotein cholesterol (LDL-C). The behaviors required to lower LDL-C levels may be difficult to adhere to if they are inconsistent with spouses' health practices, and, alternatively, may be enhanced by enlisting support from the spouse. This trial extends previous trials by requiring spouse enrollment, teaching spouses how to provide emotional and instrumental support, allowing patients to decide which component of the intervention they would like to receive, and having patients determine their own goals and action plans.Methods
Veteran outpatients with above-goal LDL-C (N = 250) and their spouses are randomized, as a couple, to receive printed education materials only or the materials plus an 11-month, nurse-delivered, telephone-based intervention. The intervention contains four modules: medication adherence, diet, exercise, and patient-physician communication. Patients decide which modules they complete and in which order; modules may be repeated or omitted. Telephone calls are to patients and spouses separately and occur monthly. During each patient telephone call, patients' progress is reviewed, and patients create goals and action plans for the upcoming month. During spouse telephone calls, which occur within one week of patient calls, spouses are informed of patients' goals and action plans and devise strategies to increase emotional and instrumental support. The primary outcome is patients' LDL-C, measured at baseline, 6 months, and 11 months. Linear mixed models will be used to test the primary hypothesis that an 11-month, telephone-based patient-spouse intervention will result in a greater reduction in LDL-C as compared to printed education materials. Various process measures, including social support, self-efficacy, medication adherence, dietary behavior, and exercise, are also assessed to explain any change, or lack thereof, in LDL-C.Discussion
Given the social context in which self-management occurs, interventions that teach spouses to provide instrumental and emotional support may help patients initiate and adhere to behaviors that lower their LDL-C levels. Moreover, allowing patients to retain autonomy by deciding which behaviors they would like to change and how may improve adherence and clinical outcomes.Trial Registration

Background
Russell’s viper envenoming is a major problem in South Asia and causes venom induced consumption coagulopathy. This study aimed to investigate the kinetics and dynamics of venom and clotting function in Russell’s viper envenoming.Methodology/Principal Findings
In a prospective cohort of 146 patients with Russell’s viper envenoming, we measured venom concentrations, international normalised ratio [INR], prothrombin time (PT), activated partial thromboplastin time (aPTT), coagulation factors I, II, V, VII, VIII, IX and X, and von Willebrand factor antigen. The median age was 39y (16–82y) and 111 were male. The median peak INR was 6.8 (interquartile range[IQR]:3.7 to >13), associated with low fibrinogen [median,<0.01g/L;IQR:<0.01–0.9g/L), low factor V levels [median,<5%;IQR:<5–4%], low factor VIII levels [median,40%;IQR:12–79%] and low factor X levels [median,48%;IQR:29–67%]. There were smaller reductions in factors II, IX and VII over time. All factors recovered over 48h post-antivenom. The median INR remained >3 at 6h post-antivenom but had reduced to <2, by 24h. The aPTT had also returned to close to normal (<50sec) at 24h. Factor VII, VIII and IX levels were unusually high pre-antivenom, median peak concentrations of 393%, 307% and 468% respectively. Pre-antivenom venom concentrations and the INR (r = 0.20, p = 0.02) and aPTT (r = 0.19, p = 0.03) were correlated (non-parametric Spearman analysis).Conclusions
Russell’s viper coagulopathy results in prolonged aPTT, INR, low fibrinogen, factors V, VIII and X which recover over 48h. Severity of clotting abnormalities was associated with venom concentrations. 相似文献15.

Aim
To validate a pretreatment verification method of dose calculation and dose delivery based on measurements with Metaplex PTW phantom.Background
The dose-response relationships for local tumor control and radiosensitive tissue complications are strong. It is widely accepted that an accuracy of dose delivery of about 3.5% (one standard deviation) is required in modern radiotherapy. This goal is difficult to achieve. This paper describes our experience with the control of dose delivery and calculations at the ICRU reference point.Materials and methods
The calculations of dose at the ICRU reference point performed with the treatment planning system CMS XiO were checked by measurements carried out in the PLEXITOM™ phantom.All measurements were performed with the ion chamber positioned in the phantom, at the central axis of the beam, at depth equivalent to the radiological depth (at gantry zero position). The source-to-phantom surface distance was always set to keep the source-to-detector distance equal to the reference point depth defined in the ICRU Report 50 (generally, 100 cm). The dose was measured according to IAEA TRS 398 report for measurements in solid phantoms. The measurement results were corrected with the actual accelerator''s output factor and for the non-full scatter conditions. Measurements were made for 111 patients and 327 fields.Results
The average differences between measurements and calculations were 0.03% (SD = 1.4%), 0.3% (SD = 1.0%), 0.1% (SD = 1.1%), 0.6% (SD = 1.8%), 0.3% (SD = 1.5%) for all measurements, for total dose, for pelvis, thorax and H&N patients, respectively. Only in 15 cases (4.6%), the difference between the measured and the calculated dose was greater than 3%. For these fields, a detailed analysis was undertaken.Conclusion
The verification method provides an instantaneous verification of dose calculations before the beginning of a patient''s treatment. It allows to detect differences smaller than 3.5%. 相似文献16.

AFLP is a novel high-resolution fingerprinting method that can be used to delineate intraspecific relationships among a large variety of fungi and plants. We demonstrate that with the appropriate technical modifications, ethidium bromide staining and non-denaturing polyacryalmide minigels can be an inexpensive and time saving alternative for screening DNA samples for suitable AFLP primer pairs. Furthermore, the recovery of ethidium bromide stained polymorphic DNA fragments is not as tedious as the recovery of isotopic DNA fragments.Abbreviations: EDTA, ethylene diamine tetraacetic acid; BSA, bovine serum albumin. 相似文献

The epidemiological features of rotavirus A (RVA) infection differ between children from developing and developed countries which could result in differences in vaccine efficacy around the world. To evaluate the impact of Rotarix? on RVA prevalence, we monitored RVA genotypes circulating in Goiania by monitoring virus in faecal samples from children that had or had not been previously vaccinated. From February-November of 2008, 220 faecal samples were collected from children in seven day-care centres. RVA detection was performed by two methodologies and the results were confirmed by polyacrylamide gel electrophoresis. From the 220 samples, eight were RVA-positive (3.6%) and five were from children that had received either one or two doses of the vaccine. All positive samples were collected from children with diarrhoea during August and September. Genotyping of the RVA characterised five of the viral samples as genotype G2P[4] and one as G8P[4], suggesting that G2P[4] was the predominant circulating genotype in Goiania during the study. The fact that vaccinated children were also infected by RVA suggests that the vaccine does not fully protect against infection by the G2[P4] RVA genotype. 相似文献

In most areas, estimating the presence and distribution of cryptic marine mammal species, such as beaked whales, is extremely difficult using traditional observational techniques such as ship-based visual line transect surveys. Because acoustic methods permit detection of animals underwater, at night, and in poor weather conditions, passive acoustic observation has been used increasingly often over the last decade to study marine mammal distribution, abundance, and movements, as well as for mitigation of potentially harmful anthropogenic effects. However, there is demand for new, cost-effective tools that allow scientists to monitor areas of interest autonomously with high temporal and spatial resolution in near-real time. Here we describe an autonomous underwater vehicle--a glider--equipped with an acoustic sensor and onboard data processing capabilities to passively scan an area for marine mammals in near-real time. The glider was tested extensively off the west coast of the Island of Hawai'i, USA. The instrument covered approximately 390 km during three weeks at sea and collected a total of 194 h of acoustic data. Detections of beaked whales were successfully reported to shore in near-real time. Manual analysis of the recorded data revealed a high number of vocalizations of delphinids and sperm whales. Furthermore, the glider collected vocalizations of unknown origin very similar to those made by known species of beaked whales. The instrument developed here can be used to cost-effectively screen areas of interest for marine mammals for several months at a time. The near-real-time detection and reporting capabilities of the glider can help to protect marine mammals during potentially harmful anthropogenic activities such as seismic exploration for sub-sea fossil fuels or naval sonar exercises. Furthermore, the glider is capable of under-ice operation, allowing investigation of otherwise inaccessible polar environments that are critical habitats for many endangered marine mammal species. 相似文献

For listeners familiar with Western twelve-tone equal-tempered (12-TET) music, a novel microtonal tuning system is expected to present additional processing challenges. We aimed to determine whether this was the case, focusing on the extent to which our perceptions can be considered bottom-up (psychoacoustic and primarily perceptual) and top-down (dependent on familiarity and cognitive processing). We elicited both overt response ratings, and covert event-related potentials (ERPs), so as to compare subjective impressions of sounds with the neurophysiological processing of the acoustic signal. We hypothesised that microtonal intervals are perceived differently from 12-TET intervals, and that the responses of musicians (n = 10) and non-musicians (n = 10) are distinct. Two-note chords were presented comprising 12-TET intervals (consonant and dissonant) or microtonal (quarter tone) intervals, and ERP, subjective roughness ratings, and liking ratings were recorded successively. Musical experience mediated the perception of differences between dissonant and microtone intervals, with non-musicians giving similar ratings for each, and musicians preferring dissonant over the less commonly used microtonal intervals, rating them as less rough. ERP response amplitude was greater for consonant intervals than other intervals. Musical experience interacted with interval type, suggesting that musical expertise facilitates the sensory and perceptual discrimination of microtonal intervals from 12-TET intervals, and an increased ability to categorize such intervals. Non-musicians appear to have perceived microtonal intervals as instances of neighbouring 12-TET intervals. 相似文献
