Trends in Angler Expenditures and Economic Contributions of Tourism at a Trophy Fishery in Texas

This thesis aimed to improve decision-maker access to economic information by testing a pricejusting methodology to annually update expenditure information for economic impacts analyses and by conducting a trends analysis of economic sector contributions to a regional economy. A secondary data analysis of historical angler survey data generated expenditure profiles adjusted over time using price indices. A replication survey was conducted to compare expenditures. Grouping anglers by trip type (one-day/multiple-day) resulted in expenditure profiles that were generally consistent over time as anglers spent approximately $75 and$130 on one-day and multiple-day trips, respectively. These expenditures resulted in total economic impacts of over $13 million. A series of automatic social accounting matrices (ASAM) were then employed to execute economic base analyses, quantifying the role of sectors in the regional economy. The tourism sector consistently contributed over 20% of gross employment and almost 10% of gross output over time

Health Researchers' Use of Social Media: Scoping Review.

BackgroundHealth researchers are increasingly using social media in a professional capacity, and the applications of social media for health researchers are vast. However, there is currently no published evidence synthesis of the ways in which health researchers use social media professionally, and uncertainty remains as to how best to harness its potential.ObjectiveThis scoping review aimed to explore how social media is used by health researchers professionally, as reported in the literature.MethodsThe scoping review methodology guided by Arksey and O'Malley and Levac et al was used. Comprehensive searches based on the concepts of health research and social media were conducted in MEDLINE, EMBASE, CINAHL, PsycINFO, ERIC, and Web of Science databases, with no limitations applied. Articles were screened at the title and abstract level and at full text by two reviewers. One reviewer extracted data that were analyzed descriptively to map the available evidence.ResultsA total of 8359 articles were screened at the title and abstract level, of which 719 were also assessed at full text for eligibility. The 414 articles identified for inclusion were published in 278 different journals. Studies originated from 31 different countries, with the most prevalent being the United States (52.7% [218/414]). The health discipline of the first authors varied, with medicine (33.3% [138/414]) being the most common. A third of the articles covered health generally, with 61 health-specific topics. Papers used a range of social media platforms (mean 1.33 [SD 0.7]). A quarter of the articles screened reported on social media use for participant recruitment (25.1% [104/414]), followed by practical ways to use social media (15.5% [64/414]), and use of social media for content analysis research (13.3% [55/414]). Articles were categorized as celebratory (ie, opportunities for engagement, 72.2% [299/414]), contingent (ie, opportunities and possible limitations, 22.7% [94/414]) and concerned (ie, potentially harmful, 5.1% [21/414]).ConclusionsHealth researchers are increasingly publishing on their use of social media for a range of professional purposes. Although most of the sentiment around the use of social media in health research was celebratory, the uses of social media varied widely. Future research is needed to support health researchers to optimize their social media use

Gonadal Hormone Levels Prior to and Following Puberty in Straightbred and Crossbred Beef Heifers

Five heifers from each of four breed groups (Angus x Angus, Charolais x Charolais and the two reciprocal crosses) were used in a study of gonadal hormone levels during the interval from 16 weeks before puberty to puberty (trial I). Puberty was defined as the first standing estrus. Two heifer calves from dams from each of the above breed groups and sired by a single Polled Hereford bull were used in a study of gonadal hormone levels from birth to weaning (trial II). Blood samples were collected at weekly intervals from trial I heifers before puberty and three times weekly during the first post puberal estrous cycle. Heifer calves in trial II were sampled once weekly. Total progestins were assayed by a competitive protein birding assay. The binding protein was 2.5%, dog plasma containing 16 ng corticosterone-1,2-3H (CBG-B3H). Duplicate plasma samples were extracted two times each with hexane for the removal of progestins. Florisil was used for the removal of unbound steroids from the CBG-B3H. The recovery of progesterone added to plasma blanks was acceptable. Extraction of different quantities of plasma yielded comparable values. Total estrogens were assayed by a radioimmunoassay utilizing an antibody kindly supplied by Dr. R. D. Randel, U. S. Range Livestock Experiment Station, Miles City, Montana. The antibody was prepared in sheep by using an estradiol-17ᵦ, 11 succinyl-bovine serum albumin conjugate. Cross reactivities with other steroids were estrone 100%, estradiol-17a 80%, estriol 60% and none with cortisol, testosterone or progesterone. Estrogens were extracted from plasma with diethyl ether. Recovery of tritiated estrogens added to plasma was 93.9 ± 2.9 percent. A correlation coefficient between duplicate samples of 0.96 (n = 22 pairs) was obtained. Subsequently, singular assays were conducted on each plasma sample. Separation of bound from unbound estrogens was accomplished with charcoal and dextran T70. The average blank from the method was 10.0 ± 6.0 picograms. Recovery of estradiol-17ᵦ added to plasma blanks was acceptable. Extraction of varying amounts of plasma yielded comparable values. The correlation between values for samples assayed in this laboratory and in the laboratory of Dr. M. L. Hopwood, Colorado State University, was 0.80 (54 pairs). No differences for hormone levels between breed groups were detected in either trial. Therefore, for further analyses breed groups were pooled. Breed groups did not differ significantly for date of birth, actual and adjusted weaning weights, date of puberty and age at puberty (trial I). Straightbred Charolais heifers were significantly heavier at birth (P\u3c.01) and at puberty (P\u3c.05) than straightbred Angus heifers. The two reciprocal crosses did not differ significantly from each other or from straightbreds for these traits. Average total progestin levels decreased from approximately 1. 5 ng/ml at 112 days before puberty to less than 1. 0 ng/ml at 70 days before puberty and then gradually rose to approximately 3.0 ng/ml the last 2 weeks before puberty. Average plasma total estrogen levels in the prepuberal heifer decreased from approximately 1000 pg/ml at 16 weeks before puberty to approximately 200 pg/ml during the last 3 weeks before puberty. The regression of age and number of days before puberty on estrogen levels accounted for 31.7 and 29.6% of the variability in estrogen levels, respectively. In a multiple regression analysis these two variables accounted for 34.2% of the variation. Average plasma total progestin levels during the first post puberal estrous cycle rose from 1 ng/ml on day 1 to a peak of 6 ng/ml on day 13 and declined from day 14 to approximately 2 ng/ml on day 19. Total estrogen levels during the first post puberal estrous cycle ranged from 100 to 220 pg/ml. The variation within samples taken on the same day was large. Average estrogen levels fluctuated between 100 and 220 pg/ml from day 1 through day 11. Levels rose steadily from 114 pg/ml on day 12 to 220 pg/ml on day 18 and then dropped to 119 pg/ml on day 19. Samples obtained on the day of estrus were not included. Average progestin levels in heifer calves from birth to 28 weeks of age remained below 1 ng/ml. Estrogen levels were high during the first 2 days of life (300 pg/ml) but decreased to less than 32 pg/ml on day 3. Elevated estrogen levels (approximately 40 pg/ml) were observed during the sixth to tenth weeks of life. During the 12th to 23rd weeks levels remained below 20 pg/ml and rose gradually from the 24th week to 58 pg/ml during the 27th week of life. The discrepancy between estrogen levels in heifers nearing puberty in trial I and the heifer calves in trial II is unexplained

Preparing Administrators To Serve Diverse Populations Of Students With Learning Challenges

The notion of integrating a curriculum is more than connecting pieces so that students can see the bigger design—in effective curriculum integration models, knowledge is meaningfully related and connects in such a way that it is relevant to other areas of learning as well as to real life (Morris, 2003). This work details the integrated efforts of two university departments, The Department of Educational Leadership and Research (ELR) and The Department of Curriculum, Instruction and Special Education (CISE), to restructure a school administrators’ preparation program to better prepare leadership candidates for meeting the challenges of student diversity relative to P-12 students with learning disabilities. This university was located in the southern region of the United States in a state with significant levels of students from diverse populations with special learning needs.  A modified action research model was used as the conceptual framework to accomplish this undertaking
