However most of the multi-criteria methods inherently include a considerable degree of subjectivity. In this study, we have attempted to reduce the subjectivity factor from water allocation decision-making process by introducing a conjoint analysis method. Opinions on the importance of a number of water allocation criteria were sought from a large number of irrigation farmers. The opinion survey data were then analyzed using the traditional conjoint analysis method which is widely used to analyze marketing surveys. The analysis allowed objective determination of the relative importance of five water allocation criteria (i.e. net farm income, percent of family working on the farm, amount paid to irrigation agency for canal water share). Each water allocation criteria was divided into three levels and utility values for each criteria level were estimated from the farmers’ preferences on five water allocation criteria (attributes). The conjoint survey results revealed that the respondents prefer that “annual net farm income” be the most important attribute in water allocation decisions. As would be expected the vast majority of the respondents overwhelmingly placed the “water price” in the last position.展开更多

We conducted a study to characterize preferences to PrEP measures within this population.Methods: HIV-negative military MSM were recruited through a closed, Lesbian, Gay, Bisexual, and Transgendered(LGBT) military social media group. The survey was anonymous, and consisted of five experimentally varied attributes in service delivery: dosing method, provider type, visit location, lab work evaluation location, and dispensing venue.Relative importance and part-worth utility scores were generated using hierarchical bayes(HB) estimation, and the randomized first choice model was used to examine participation interest across eight possible PrEP program scenarios.Results: A total of 429 participants completed the survey. Among the eight scenarios with varying attributes, the most preferred scenario featured a daily tablet, PrEP injection or implant, along with a military provider, smartphone/telehealth visit, and on-base locations for lab evaluation and medication pick-up. The results also emphasized the importance for providers to be familiar with PrEP prescription knowledge, and to provide interactions sensitive to sexual identity and mental health.Conclusions: A PrEP program consisting of daily tablet is preferred in military healthcare settings is preferred. Longacting implants and injections are also desired.展开更多

The company intends to launch its product into a new market and surveys the likelihood of getting international. The survey helps the company to gather information from clients regarding product characteristics, price, method of distribution, and promotion, according to customer preferences. Having these data, it is made a marketing simulation using conjoint analysis in order to get the optimal marketing mix in launching the product on a new market. The optimal marketing mix is given by the highest mix of utility for the clients, but sometimes the marketing manager would choose a little bit lower utility mix, forced by the company restrictions.展开更多

The patients may be more resistant to conservative treatment than those with isolated subacromial impingement. Even though, the surgical options of this disease remain controversial. It has been reported that tenotomy and tenodesis of the biceps tendon were usually utilized. However, persistent pain, deformity, and muscle cramping were frequently observed. Transfer of the LHBT to the conjoint tendon was originally described by Post and Benca in 1982.4 Verma et all has performed the transfer under arthroscopy since 2004. Eighty percent of their patients reported good results with a minimum 2 years of follow-up. However, there was a steep learning curve to become proficient in their technique. We devised a more convenient transfer compared with O＇Brien＇s technique. Six patients received our modified arthroscopic transfers from May 2006 to May 2007. All of them obtained good results.展开更多
