What Provosts Think Librarians Should Know

Three senior leaders will reveal what Provosts worry about when they think about libraries. Charged to be frank and direct, they will talk about what they value in libraries, but also about what the challenges are that they face that affect how they think about libraries. Budget, facilities, and their perception of what faculty and students want and need will all play into this. This session is an opportunity for a frank exchange of views with real provosts—without worrying about how they react

New procedures in estimating feed substitution rates and in determining economic efficiency in pork production II. Replacement rates of corn and soybean oilmeal in fortified rations for growing-fattening swine on pasture

A previous bulletin reported results from an experiment designed to predict substitution rates and economic optima in corn/soybean oilmeal rations for growing and fattening hogs in drylot.2 Principles and analytical models were included which illustrate that the least-cost ration depends both on (1) the marginal rate of substitution between feeds and (2) the ratio of feed prices. These basic concepts will not be repeated in this bulletin. Since more hogs are farrowed in spring than in fall, the research reported in this study was conducted for growing and fattening hogs raised on pasture. Like the drylot study, the objectives of the pasture experiment were to estimate: (1) the production function, (2) the substitution rate between corn and soybean oilmeal at different points on the production surface, (3) the least-cost ration for different soybean oilmeal/corn price ratios, (4) the relationship between the rate of hog gains and the input of corn and soybean oilmeal and (5) the proportion of the years in which a least-cost feeding system results in greater profits than a least-time feeding system. Substitution between major classes of feed such as corn and soybean oilmeal is possible mainly where the rations are fortified with appropriate quantities of trace minerals (as well as antibiotics in the case of drylot feeding). These fortifying elements have been included in the rations of this study

Factors that influence resorts’ development in the Municipality of Dauin, Philippines

It is essential to adapt and improve tourism supply in order to respond to new tourist demand dynamics. This study tries to find out the factors that influence resorts development in Municipality of Dauin, Negros Oriental using a descriptive survey. A researcher-made survey questionnaire was administered to twenty-two (22) registered resort operators, as recorded in the Municipal Treasurer’s Office. Specifically, the study aimed to identify the factors that influence resorts development in terms of recreational activities, resting and relaxation, personal values, social experiences, and enriching and learning experiences. Data were collected mainly from registered resort businesses, after which results were tabulated and analyzed.The findings show that resorts development has indeed made a significant impact on the tourism trade in the municipality. Recreational activities were the highest factor that contributed to the increased number of resorts in the area. This implies that tourists visit the resorts largely for recreation such as outdoor activities, sports, entertainment, fun, and doing something out of the ordinary

Reasons for using inhalants: evidence for discrete classes in a sample of incarcerated adolescents.

The use and abuse of inhalants continue to be among the most pernicious, curious, and least understood of drug use behaviors. The purpose of this study was to identify specific subgroups of adolescents based on their reasons for using inhalants. Data regarding reasons for using inhalants were examined using latent profile analysis. A three-class solution exhibited the best fit with the data. Although validation analysis revealed that the classes did not differ on demographic characteristics, classes exhibited significant differences across numerous clinical measures, including anxiety, problems associated with using substances, global symptom severity, and number of different types of inhalants used. Results indicate heterogeneity for reasons for use of inhalants and associated psychological distress. Findings may provide clues to future taxonomic development of inhalant abuse phenomena and prevention.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/61149/1/Reasons.pd

Prevalence, timing, and predictors of transitions from inhalant use to Inhalant Use Disorders

BACKGROUND: Few studies of the natural history of DSM-IV inhalant substance use disorders (I-SUDs) have been conducted. This investigation examined the prevalence, timing, and predictors of transitions from inhalant use to formal I-SUDs among inhalant users within a nationally representative sample. METHODS: Participants were 664 U.S. residents participating in the 2000-2001 National Epidemiologic Survey on Alcohol and Related Conditions who reported lifetime inhalant use. Respondents completed structured interviews assessing DSM-IV psychiatric/substance use disorders. Bivariate and Cox regression analyses were conducted to identify risk factors for transitions from inhalant use to I-SUDs. RESULTS: Nearly one in five (19.4%) persons initiating inhalant use developed an I-SUD. Most I-SUD transitions were to inhalant abuse rather than inhalant dependence. Risk for development of I-SUDs was greatest in the first year following initiation of inhalant use and low thereafter. Multivariate proportional hazards models indicated that presence of a mood/anxiety disorder (HR=7.7, CI=3.1-18.9) or alcohol use disorder (HR=11.9, CI=5.46-26.00) antedating initiation of inhalant use predicted significantly elevated risk for I-SUDs, whereas being married conferred a lower risk for onset of I-SUDs. CONCLUSIONS: I-SUDs were relatively common among inhalant users, generally occurred in the year following initiation of inhalant use, and were associated with early-onset mood/anxiety and alcohol use disorders. Given the young average age at onset of inhalant use and the rapidity with which most I-SUDs developed, interventions directed to adolescents who have initiated inhalant use might be effective in reducing the proportion of inhalant users who develop I-SUDs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/61908/1/Transition.pd
