Willingness to pay for compulsory deworming of pets entering Sweden to prevent introduction of Echinoccoccus multilocularis

To investigate if the Swedish entry rules for pets to prevent the introduction of Echinococcus multilocularis (EM) are proportional (i.e. that their costs do not exceed the value of their benefits), a dichotomous-choice contingent valuation study was conducted. The study was performed before the first case of EM was detected in Sweden in February 2011. About 5000, randomly selected, Swedish citizens were invited to participate and 2192 of them (44%) accepted to do so. Missing information on whether or not one would accept to pay for keeping the rules for 143 respondents resulted in 2049 observations (41%) available for the estimation of willingness to pay (WTP), and missing information on personal characteristics for another 274 respondents reduced the number of observations available for sensitivity analysis to 1775 (36%). Annual expected WTP for keeping the rules ranged between € 54.3 and € 99.0 depending on assumptions about compensations demanded by respondents not willing to pay. The estimates are conservative since only answers from respondents that were absolutely certain they would pay the suggested bid were regarded as yes-responses. That WTP is positive implies that Swedish citizens perceived the benefits of the rules to be larger than their costs.     

Conserving the Eastern Hellbender Salamander

Through a mail survey of 541 residents and riparian landowners in the area surrounding the Blue River watershed of southern Indiana, we examined perceptions and intended behaviors toward the eastern hellbender (Cryptobranchus alleganiensis alleganiensis), an aquatic salamander experiencing drastic population declines due to anthropogenic causes. While anecdotal reports attribute hellbender mortality and removal to anglers and pet collectors, only 5% of respondents reported these negative behaviors. Misconceptions among anglers and the general public about the eastern hellbender were less prevalent than anticipated. Anglers, recreational boaters, riparian landowners, and respondents who were previously familiar with the hellbender displayed more positive attitudes toward the animal than other groupings of individuals. Data collected in this article shaped a detailed education and outreach campaign based on the principles of community-based social marketing.     

Key Attributes Influence the Performance of Local Weed Management Programs in the Southwest United States

In the southwestern United States, local weed management programs are increasingly important in weed prevention and control; however, little is known about the effectiveness of different local approaches to weed management. We surveyed coordinators of 53 local weed management programs in Arizona, Colorado, New Mexico, and Utah to determine how 4 key program attributes (interagency coordination, volunteer participation, regulatory authority and enforcement, and the state in which the program was located) were related with 4 performance measures: weed control, public education and outreach, weed monitoring, and integrated weed management. Based on the responses of 42 program coordinators (79%) we found that 1) weed programs that coordinated their activities with other organizations and those with citizen volunteers conducted more monitoring, but programs that did not coordinate or use volunteers treated more of their infested acreage; 2) programs that used a light-handed regulatory approach conducted more weed control than those with more punitive enforcement regimes or no enforcement authority; and 3) Colorado programs conducted more outreach and education than did programs in the other 3 states. Thus, although volunteer involvement and interagency coordination contributed to the performance of the local weed programs studied, particularly in monitoring, they have not compensated for the lack of locally enforceable weed regulations or adequate funding. Successful weed management in southwestern United States will require adequately funded, locally adapted approaches supported by locally enforceable weed regulations.     

深圳野生动物园游客对保护教育项目的选择偏好

动物园是对公众进行保护教育的重要基地,游客观赏和教育项目偏好是影响游客管理决策的重要因素。本研究采用选择实验法构建深圳野生动物园庭院探秘之旅项目的随机参数模型(random parameter logit,RPL),将观看项目动物、体验项目、动物生态解说、纪念品及费用5个属性纳入评估模型,分析各属性的偏好及愿付价值(willingness to pay,WTP)。结果表明:游客希望该项目在现状基础上进行属性提升,且相对偏好于观赏多种动物以及进行深度体验,这两个属性的WTP分别为28.71和11.86元/(次·人);若项目费用升高,则游客对其选择性随之下降。利用潜在类别模型(latent class model,LCM)进行该项目游客市场区隔分析:第一个类群为偏好多样化的游客,占受访者的35.7%,第二类群为偏好单一型游客,倾向于深度体验项目,这部分游客较多,占64.3%。可开展后场参观、动物饲料制作等游客参与式深度体验项目,招募志愿者辅助完成讲解站、主题日等保护教育活动,以提高动物园对游客的吸引力。     

Investigating the value dairy farmers place on a reduction of lameness in their herds using a willingness to pay approach

A survey was conducted to elicit dairy farmers’ willingness to pay (WTP) to reduce the prevalence of lameness in their herds. A choice experiment questionnaire was administered using face-to-face interviews of 163 farmers in England and Wales. Whole herd lameness assessments by trained researchers recorded a mean lameness prevalence of nearly 24% which was substantially higher than that estimated by farmers. Farmers’ responses to a series of attitudinal questions showed that they strongly agreed that cows can suffer a lot of pain from lameness and believed that they could reduce lameness in their herds.Farmers’ mean WTP to avoid lameness amounted to UK£411 per lame cow but with considerable variation across the sample. Median WTP of UK£249 per lame cow was considered a better measure of central tendency for the sample. In addition, the survey found that farmers had a substantial WTP to avoid the inconvenience associated with lameness control (a median value of UK£97 per lame cow) but that they were generally prepared to incur greater inconvenience if it reduced lameness. The study findings suggest that farmers need a better understanding of the scale and costs of lameness in their herds and the benefits of control. To encourage action, farmers need to be convinced that lameness control measures perceived as inconvenient will be cost effective.     

Is Willingness to Pay for Non-Consumptive Wildlife Watching Falling? Evidence From Three Rounds of the National Survey of Fishing,Hunting, and Wildlife-Associated Recreation

Since 1955, the United States Fish and Wildlife Service has conducted the National Survey of Fishing, Hunting, and Wildlife-Association Recreation (FHWAR) with the purpose of evaluating outdoor recreation. Using the socioeconomic, activity, and contingent valuation data collected from the last three rounds of this national survey (2001, 2006, 2011), econometric modeling demonstrates that variables such as age, income, gender, and type of land visited (public/private) explain variation in wildlife watching willingness to pay (WTP) and consumer surplus (CS). Although not having been fully investigated in the previous FHWAR contingent valuation literature, results suggest that distinguishing between in-state and out-of-state wildlife watching is important. Additionally, analyses indicate that CS for out-of-state wildlife watching along with CS and WTP for in-state wildlife watching are temporarily reliable. Given the study period overlaps the recent recession, this outcome suggests that welfare is stable across time and in the face of business cycles.     

条件价值评估法(CVM-WTP)在玛曲草地生态系统恢复中的应用

Evaluation of veterinary public practice education programs

OBJECTIVE: To describe the number and types of veterinary professional degree and certificate programs providing education in the area of public practice to veterinarians and determine the availability of these programs via distance learning. PROCEDURES: Web-based internet searches were performed for programs for veterinary public practice or public health, population medicine, or Master's degree in Epidemiology. The information reviewed was derived from individual school and program Web sites and from personal e-mail correspondence with school administrators. RESULTS: 17 professional degree and 4 certificate programs were available to provide education and training in the areas of public practice and population medicine to veterinarians. Twelve of these programs have begun since 1998. Of the 17 professional degree programs, 7 are located in the United States and 10 are located in other countries. Nine of the professional degree programs provide education through traditional teaching methods, and 8 provide education and training through distance learning. CONCLUSIONS: During the preceding 5 years, the number of programs available to educate and train veterinarians in the areas of public practice and population medicine has increased. Distance learning is being used to increase capacity and reach a broader audience of veterinarians. With the increase in programs has come an increase in capacity to educate and train veterinarians in the fields of population medicine and public practice. The impact and sustainability of this increased capacity have not been evaluated.     

Public-health education at Kansas State University

What are veterinary medical and public-health professionals doing to remedy the immediate and impending shortages of veterinarians in population health and public practice? This question was addressed at the joint symposium of the Association of American Veterinary Medical Colleges and the Association of Schools of Public Health, held in April 2007. Thinking locally, faculty and students at Kansas State University (KSU) asked similar questions after attending the symposium: What are we doing within the College of Veterinary Medicine to tackle this problem? What can we do better with new collaborators? Both the professional veterinary curriculum and the Master of Public Health (MPH) at KSU provide exceptional opportunities to address these questions. Students are exposed to public health as a possible career choice early in veterinary school, and this exposure is repeated several times in different venues throughout their professional education. Students also have opportunities to pursue interests in population medicine and public health through certificate programs, summer research programs, study abroad, and collaborations with contributing organizations unique to KSU, such as its Food Science Institute, National Agricultural Biosecurity Center, and Biosecurity Research Institute. Moreover, students may take advantage of the interdisciplinary nature of public-health education at KSU, where collaborations with several different colleges and departments within the university have been established. We are pleased to be able to offer these opportunities to our students and hope that our experience may be instructive for the development of similar programs at other institutions, to the eventual benefit of the profession at large.     

Perception of Asian carp as a possible food source among Missouri anglers

Silver and bighead carps were imported from China to the United States in the 1970s as a biological control mechanism for improving water quality. After escaping captivity, both species spread into the Mississippi River Basin and now threaten to enter the Great Lakes. Human consumption is one solution, but many Americans believe that carp is unsavory. A random sample of 2,000 licensed anglers in Missouri was asked to complete a mail-back questionnaire about Asian carp, yielding a 27% response rate (n = 465). Results indicated that knowledge and perception about carp were poor, and food neophobia (fear of new foods) scores were above average. Less than 15% of respondents had eaten carp, but nearly 53% were willing to try. Marketing should focus on the benefits of consumption while downplaying any possible concerns. Although education programs are worthwhile, taste might be more influential to change public attitudes toward Asian carp.     

Range Education in the 21st Century: Striking the Balance to Maintain a Relevant Profession

Range science education programs strive to keep pace with the changing needs of the range profession and to ensure that range graduates are knowledgeable, skilled, and able to address contemporary, complex problems unique to rangelands. Today, range education programs face many challenges in our ability to meet the demands and needs of our profession and society. First, our capacity to meet the demands for range science graduates has been diminished by 1) elimination or restructuring of academic rangeland science programs, 2) reduced numbers of range-trained faculty teaching rangeland courses, and 3) limited public awareness of degrees and careers in rangeland science and management. Second, range education programs are challenged to strike a balance between retaining traditional basics and modernizing curriculum to include contemporary concepts and technologies. Third, range science graduates need to understand the current social, political, and economic context of resource management, including global change issues that are of paramount concern to society. We propose multiple approaches to meet these challenges: 1) perform needs assessments with diverse stakeholders to ensure that range education programs are relevant to society's needs and address the future of the profession; 2) find innovative approaches to strike the educational balance between fundamental concepts, practical field experiences, and mastery of technical and interpersonal skills; 3) collaborate across institutional boundaries to share educational resources and incorporate course formats that meet the diverse needs of today's students; 4) examine and align professional qualifications, educational standards, and curriculum by defining learning outcomes and core competencies needed by well-trained range professionals; and 5) communicate the unique features of the rangeland profession that solidify its position among the disciplinary pillars of natural resource science and management.     

Education of veterinary medical and other public health providers: linking interventions with health outcomes

A systematic literature review was performed to summarize the nature, implementation, outcomes, and long-term impacts of previously instituted interventions and programs aimed at educating veterinary public health providers. A logic model was developed to direct the literature search strategy, provide a framework for evaluating the relationship between veterinary public health professional education and their associated population health outcomes, and guide future training development and recommendations for the education of veterinary health professionals. Our literature review indicates that there is a relative lack of published literature that connects veterinary public health educational interventions to population health outcomes. Reasons for the lack of evidence to connect educational programs and population health outcomes include the evaluation of outcomes on a short-term rather than intermediate- or long-term basis, a lack of experimental studies, and infrequent grounding in population health or educational theory. Future intervention recommendations as suggested in the reviewed articles are also summarized.     

First report of Cryptosporidium deer-like genotype in Kenyan cattle

The objective of the study was to identify Cryptosporidium genotypes from feces collected from urban and peri-urban dairy cattle in Nairobi, Kenya, in order to determine their zoonotic potential. DNA was extracted from 34 samples that were diagnosed positive by the modified Ziehl-Neelsen technique. Two Cryptosporidium isolates examined at the 18S rRNA locus were identified as the deer-like genotype by DNA sequencing. As public health officials are facing the difficult decision whether to allow urban livestock production because of its economic benefits and a livelihood asset to the urban communities, or to ban it for its public health risks, the finding of non-zoonotic genotypes in a smallholder dairy system has significant public health as well as economic implications that merit further investigation.     

Observations on a Swine Herd Health Program

Observations on a swine herd health program are reported. A primary purpose was to show that such programs could provide economic benefits to swine breeders and sources for breeding stock of minimum disease status. The possible influence of diseases of swine, including atrophic rhinitis and virus pneumonia, on both aspects are discussed. The inadequacy of knowledge of diseases of swine, both specifically and generally, is pointed out. Veterinary supervision of a swine herd will result in economic benefits to an average capable owner. There is both merit and need for such programs, but as to what health standards would be reasonable, practical, and meaningful, is still not clearly defined.     

The concept of rural community practice (RCP)

The need to devote more human resources to veterinary public practice to cope with escalating threats to biological security, public health, and economic prosperity, while also addressing societal value changes, has been widely recognized and supported. Most envisage increasing the numbers of veterinarians in government employment. Why not at least combine this initiative, wherever possible, with far greater involvement of rural practitioners to deliver contractual public-practice services and provide an enhanced community interface? This could make the difference between having a local practice in a community or none at all, as well as promising to be more cost effective. The concept of rural community practice (RCP) envisages combining traditional services provided in a "mixed-animal" veterinary practice with an expanded portfolio of public-practice and communication services that meet the emerging animal, public, and ecosystem health needs of the collective community, not just those of animal owners. These services could include those involving active sentinel surveillance programs for both domestic animal and wildlife diseases; on-farm food safety; bio-security; traceability and export certification and audit programs; disease investigation, including foreign animal diseases; surge capacity emergency response; managing for ecosystem health; and client and community education. An expanded practice team of animal-health professionals and technologists, led by veterinarians, would deliver these services. This RCP approach should have the potential to make rural practice more attractive from economic, lifestyle, and job-satisfaction perspectives; to enhance the visibility and recognition of the profession; and to respond to changing and new societal needs. It also promises to maintain a stable network of veterinary practices in rural communities. In addition, the recognition of veterinary medicine as a public good should provide for consideration of increased investment by levels of government. At the same time, this new model could help meet the demands of animal and public-health government agencies that face expanding responsibilities during a sustained climate of reduced budgetary resources.     

Factors affecting Canadian veterinarians' use of analgesics when dehorning beef and dairy calves

Data collected through a national, randomized mail survey (response rate 50%) were used to identify reasons why veterinarians were likely (i) to use analgesic drugs when dehorning calves, and (ii) to perceive dehorning without analgesia as very painful. Logistic regression analysis indicated that veterinarians were more likely to be analgesic users the more they perceived that dehorning without analgesia was painful (OR = 1.7, P < 0.001). Other positive influences were if the veterinarian worked in British Columbia or Alberta (OR = 5.9, P = 0.005), and if they were primarily in dairy practice (OR = 3.7, P = 0.012) rather than beef practice. This effect of dairy practice was negated if the veterinarian also perceived that owners were unwilling to pay for analgesia (interaction term: OR = 0.25, P = 0.038). Veterinarians were also less likely to perceive dehorning without analgesia as very painful if they perceived that owners were unwilling to pay (OR = 0.58, P = 0.029). However, this effect on pain perception was offset by concern for personal safety (OR = 2.7, P = 0.015). The results are consistent with the relatively high level of outreach about animal welfare among farmers and veterinarians in the western provinces. The results confirm that many veterinarians' approach to pain management for dehorning is influenced considerably by concern about cost. However, pain management for dehorning is not expensive and there is unequivocal evidence that dehorning calves without pain management causes significant distress. Continuing education of veterinarians should help to increase analgesic usage.     

Joint degree programs in public health

Public health and veterinary medicine share a focus on population health and primary prevention, along with a commitment to preparedness, response, and recovery in the event of disease outbreaks. Public-health and veterinary professional degree programs share commonalities in their educational accreditation requirements related to epidemiology and public-health practice. The initiation of a number of joint professional degree programs over the last five years, including the joint Doctor of Veterinary Medicine and Master of Public Health (DVM/MPH), represents an exciting development for inter-professional education for veterinarians interested in public health. Various models for joint DVM/MPH educational programs are discussed, including pre-veterinary public-health credentialing, integrated programs, and post-DVM executive programs. Collaborations between colleges of veterinary medicine and schools of public health show great promise in both educational and research innovation.     

Equine Farm Operators: An Underserved Target Audience for Conservation Practice Outreach?

Equine farms account for an increasing proportion of land use in many areas of the United States. Despite this, equine farm operators have often been neglected by researchers and resource professionals when land management decisions are concerned and little is understood of this community's awareness and use of conservation practices. This study assessed the prevalence of conservation messages in equine-related trade magazines using content analysis. In-depth interviews were also conducted with equine farm operators to assess their understanding and use of conservation practices. Conservation-related material in equine media is relatively rare when compared with traditional livestock magazines. Equine and stable owners are generally motivated to protect on-farm resources but are not very aware of the off-farm effects of their operations. Several common livestock conservation practices are being used by many facilities, but the motivation for their use is not based on environmental concern, and operators are generally unaware of the environmental benefits of these practices. More outreach and education directed at equine farm operators is needed.     

Home on the Digital Range: Ranchers’ Web Access and Use

Access to the Internet continues to grow in rural areas, ensuring ranchers will have increasing opportunities to use the Web to find information about management practices that may provide them ecological and financial benefits. Although past studies have examined the role of the Internet in informing daily decision making by agricultural producers, no studies have focused specifically on the use of the Internet by ranchers in the western United States. This study uses a mixed-methods approach (a survey and semistructured interviews) to assess the extent and patterns of ranchers’ Internet use in Colorado and Wyoming, identify barriers to greater use, and establish a typology of Web use behavior by ranchers. Our findings indicate that Internet use is widespread and that age, education, and risk tolerance predict the extent to which a rancher will rely on the Internet for day-to-day ranch management. A cluster analysis delineated four distinct types of Web usage among ranchers: uninfluenced, focused on sales and herd management, moderately influenced, and an Internet-reliant type. Outreach personnel can use this classification to determine the potential utility of digital outreach tools for their programming on the basis of their target audience and outreach topics.
