Identifying the Behavioral Intent to Use Social Media through the application of UTAUT in ANR and Turfgrass Extension

Little research exists on the role Extension Agricultural and Natural Resources professionals play in communicating information about new turfgrass cultivars. In an effort to analyze behavioral intentions related to social media and its use in the turfgrass industry, the researchers drew from the unified theory of acceptance and use of technology (UTAUT). A pilot instrument was developed to measure the intent of University researchers and county-based Extension professionals to use social media to disseminate turfgrass information, as well as their use of social media for seeking turfgrass information. This case study examined the role of county-based ANR Extension professionals across six states, analyzing their role as either creators or disseminators of ANR and turfgrass information, their intent to use social media, and their use of these communications to engage with ANR and turfgrass information. Findings of this study show that Facebook is the primary communications channel used by county-based Extension professionals. Further, it has been determined that the role of the county-based Extension professional in “creating” verses “using” previously established research-based information to disseminate to clientele is not well-defined. Broader implications include examination of performance expectations of county-based personnel related to their use of social media for communicating turfgrass information

Pupil Voice Groups: The Impact on Schools and Students

Over 30 years ago, the United Nations Convention on the Rights of the Child passed legislation allowing children under the age of 18 to express their concerns in circumstances and decisions that affect them. Because one impact on children under the age of 18 is the educational system, Scotland education has integrated opportunities for students to be involved in the educational process. Pupil voice groups are one of the techniques that have been implemented in Scotland and throughout Europe. These groups allow students to have a voice in their education that may impact development. Researchers sought to identify the impacts of pupil voice groups on student development, the surrounding community, and the school. Researchers identified primary school students from years P-3 to P-6 (7 to 12 years of age) involved in pupil voice groups. Data were collected through focus group interviews, in which themes surrounding benefits, drawbacks, and impacts on the school and community emerged. Results indicated that these groups improve the school and community, and students believe these opportunities allow them to share their opinions on their education. The researchers recommend that further research should examine the perceptions of previously interviewed students towards involvement in pupil voice groups, and the use of pupil voice groups outside of the United Kingdom

Relationships between student achievement and levels of computer technology integration by Texas agriscience teachers

The purpose of this study was to determine if agriscience teacher integration of instructional technology was related to student achievement. Knowledge of these correlations will assist teacher educators in offering more appropriate professional development opportunities for agriscience teachers. This information will also assist secondary schools in making decisions regarding technology purchases for agriscience departments. Instructional technology researchers have worked since the 1960s to gain a better understanding of the role that instructional technology plays in student achievement. Many researchers have found that instructional technology influences student learning. In the early 1980s Richard Clark published controversial findings that media has no influence on student learning. These conflicting findings led to the development of this study. A survey was developed to collect information on the level at which teachers integrate technology into their instruction. The instrument was pilot tested, and a reliability measure of .95 was found for the 42 items measuring the technology skills of teachers. Section three of the instrument had a reliability of .93 for the nine items that were used to measure teacher integration of technolo gy. Teachers' demographics, teachers' technology integration skill levels, teachers' administrative use of technology skill levels, and teachers' technology integration levels were collected from a random sample of 150 agriscience teachers in Texas. Student achievement was measured using the Texas Assessment of Academic Skills (TAAS) test. Student data were collected on 10th grade students in classes taught by the 150 teachers selected to participate in the study. The Texas Education Agency provided all TAAS data in a single data file. The primary student variables used in the study to quantify math, reading, and writing achievement were the total number of multiple choice items correct for each of these three subject areas. A low positive correlation was found between student achievement in math and teacher instructional technology integration level (.14). Negligible positive correlations (r < .10) were found between teacher instructional technology integration level and student achievement on the writing portions and reading portions of the TAAS

All-Terrain Vehicle Safety Knowledge and Behaviors Among 4-H’ers

Youth in rural areas are exposed to all-terrain vehicles, but little is known about their knowledge of all-terrain vehicle safety and their likelihood to apply such knowledge. The purpose of this needs assessment was to determine what rural 4-H youth in Georgia knew about all-terrain vehicle safety and operating procedures. A total of 287 rural 4-H youth in fourth through sixth grade completed a previously validated all-terrain vehicle safety knowledge and behavior test administered during a regularly scheduled afterschool club meeting. Only 13.6% ( n = 39) of respondents passed the safety test, while 13.9% ( n = 15)of those who had taken an all-terrain vehicle safety course ( n = 108) passed. Of youth who passed the test, 36% had at least three years of riding experience. Participation in an all-terrain vehicle safety course could save a child’s life. Still, this study revealed that retention of safety information from these courses is limited, and riding experience does not necessarily imply adequate safety knowledge. Youth development professionals should consider partnering with local all-terrain vehicle dealerships to provide hands-on safety training experiences on properly equipped machines where youth can demonstrate their safety knowledge and behaviors and be evaluated by trained adult

An Assessment of the Needs of Georgian Secondary Agricultural Educators

This purpose of this study was to determine the perception of secondary educators involved in Future Farmers of Georgia (FFG) schools throughout the country of Georgia concerning their needs for furthering the existing framework of agricultural education. The researchers used a modified focus group method to meet the aformentioned purpose of this study. The population for this study consisted of the high school agricultural education teachers and their administrators who were participating in the FFG Program (n=14). Qualitative data collected from the probe (first round) was used to generate a series of 46 statements. In the second round participants were asked to rank the 46 statements using a five point Likert-type scale. Due to events in the Former Republic of Georgia, the third round could not be conducted. Therefore, the researchers concluded that the round two data would be used to meet the purpose and objectives of this study. Participants strongly agreed that the FFG program strengthens leadership skills among their students and students have become more involved in practical/labor activities. They also agreed that gaining knowledge and skills from the FFG program will improve the future development of agricultural education in the country. Participants also strongly agreed that improvement of schools’ materials, technology, and development are necessary to improve the FFG program. Participants were either neutral or agreed with the following statements: due to the FFG program, academic performance has been increased among students; and students have greater academic success in history and geography

In vivo microdialysis to determine subcutaneous interstitial fluid penetration and pharmacokinetics of fluconazole in intensive care unit patients with sepsis

The objective of the study was to describe the subcutaneous interstitial fluid (ISF) pharmacokinetics of fluconazole in critically ill patients with sepsis. This prospective observational study was conducted at two tertiary intensive care units in Australia. Serial fluconazole concentrations were measured over 24 h in plasma and subcutaneous ISF using microdialysis. The concentrations in plasma and microdialysate were measured using a validated high-performance liquid chromatography system with electrospray mass spectrometer detector method. Noncompartmental pharmacokinetic analysis was performed. Twelve critically ill patients with sepsis were enrolled. The mean in vivo fluconazole recovery rates +/- standard deviation (SD) for microdialysis were 51.4% +/- 16.1% with a mean (+/- SD) fluconazole ISF penetration ratio of 0.52 +/- 0.30 (coefficient of variation, 58%). The median free plasma area under the concentration-time curve from 0 to 24 h (AUC(0-24)) was significantly higher than the median ISF AUC(0-24) (340.4 versus 141.1 mg . h/liter; P = 0.004). There was no statistical difference in median fluconazole ISF penetration between patients receiving and not receiving vasopressors (median, 0.28 versus 0.78; P = 0.106). Both minimum and the maximum concentrations of drug in serum (C-max and C-min) showed a significant correlation with the fluconazole plasma exposure (Cmax, R-2 = 0.86, P < 0.0001; Cmin, R-2 = 0.75, P < 0.001). Our data suggest that fluconazole was distributed variably, but incompletely, from plasma into subcutaneous interstitial fluid in this cohort of critically ill patients with sepsis. Given the variability of fluconazole interstitial fluid exposures and lack of clinically identifiable factors by which to recognize patients with reduced distribution/exposure, we suggest higher than standard doses to ensure that drug exposure is adequate at the site of infection

Factors Influencing 4-H Club Enrollment and Retention in Georgia

Middle school aged 4-H member participation is on the decline across the nation. Research has identified reasons for declining 4-H club participation, including conflicting time commitments (with school and community activities) and opinions that the program was boring or for little kids. This study sought to gain a clearer understanding of why 4-H member involvement in Camden County, Georgia has steadily declined in recent years. The most prevalent reason listed for leaving the Camden County 4-H program was that the 4-H meeting conflicted with school and community activities. Other reasons listed included wanting to be with friends in a relaxed setting, not liking the activities and lessons at the special interest club meetings, and not feeling welcome in the 4-H club meetings. The 4-H members who continued with the program had 100% parental involvement – the number one indicator of continued 4-H participation

Acute effects of nitrate-rich beetroot juice on blood pressure, hemostasis and vascular inflammation markers in healthy older adults: A randomized, placebo-controlled crossover study

Aging is associated with a vasoconstrictive, pro-coagulant, and pro-inflammatory profile of arteries and a decline in the bioavailability of the endothelium-derived molecule nitric oxide. Dietary nitrate elicits vasodilatory, anti-coagulant and anti-inflammatory effects in younger individuals, but little is known about whether these benefits are evident in older adults. We investigated the effects of 140 mL of nitrate-rich (HI-NI; containing 12.9 mmol nitrate) versus nitrate-depleted beetroot juice (LO-NI; containing ≤0.04 mmol nitrate) on blood pressure, blood coagulation, vascular inflammation markers, plasma nitrate and nitrite before, and 3 h and 6 h after ingestion in healthy older adults (five males, seven females, mean age: 64 years, age range: 57–71 years) in a randomized, placebo-controlled, crossover study. Plasma nitrate and nitrite increased 3 and 6 h after HI-NI ingestion (p &lt; 0.05). Systolic, diastolic and mean arterial blood pressure decreased 3 h relative to baseline after HI-NI ingestion only (p &lt; 0.05). The number of blood monocyte-platelet aggregates decreased 3 h after HI-NI intake (p &lt; 0.05), indicating reduced platelet activation. The number of blood CD11b-expressing granulocytes decreased 3 h following HI-NI beetroot juice intake (p &lt; 0.05), suggesting a shift toward an anti-adhesive granulocyte phenotype. Numbers of blood CD14++CD16+ intermediate monocyte subtypes slightly increased 6 h after HI-NI beetroot juice ingestion (p &lt; 0.05), but the clinical implications of this response are currently unclear. These findings provide new evidence for the acute effects of nitrate-rich beetroot juice on circulating immune cells and platelets. Further long-term research is warranted to determine if these effects reduce the risk of developing hypertension and vascular inflammation with aging

Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans

Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in 25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16 regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP, while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium (LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region. Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the refined data for existing association signals, we estimate that these loci now explain ∼38.9% of the familial relative risk of PrCa, an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent signals within the same regio
