مستخلص: The agricultural industry lacks qualified workers, suggesting students may not participate in opportunities that effectively develop their employability skills. We used a phenomenological case study approach to investigate Texas A&M University College of Agriculture and Life Sciences students' career-readiness and factors influencing career-readiness. We conducted interviews with 19 juniors and seniors. Open coding procedures revealed five emergent themes--"Career Advice-Seeking Behavior," "Employability Skills Development," "Network Establishment," "Relevant Experiences," and "Personal Growth." Findings indicate that students do not take advantage of University resources to help them with career preparation. Findings also revealed a lack of employability skills development, especially relating to students' communication and science communication skills. Students identified high-impact experiences they believed improved their employability skills. We recommend strategies for educators to improve agriculture students' career-readiness and offer research recommendations to examine career-readiness factors that may help prepare students to meet 21st century agricultural workforce demands.

مستخلص: Purpose: This study sought to investigate how secondary agriculture teachers' characteristics influence their perceived ability to teach students decision-making skills. Design/Methodology/Approach: We used a cross-sectional survey research design and distributed the instrument to secondary agriculture teachers in the U.S. via Facebook. We received 151 usable responses and conducted a multiple regression and mediation analysis. Findings: The regression model accounted for 34.97% of the variance in teachers' perceived ability to teach decision-making skills and explained a statistically significant amount of variation in the outcome (F(16, 129) = 4.34, p < 0.001). Teaching efficacy, teaching style, decision-making beliefs, and years of service statistically and significantly influenced the outcome. In addition, 29.35% of the total effect of decision-making beliefs on perceived ability to teach decision-making is mediated through teaching efficacy. Practical Implications: Findings can inform the development of workshops and educational resources intended to improve agriculture teachers' perceived ability to teach students decision-making skills, thereby enhancing their ability to teach students how to make decisions. Theoretical Implications: Teachers' psychological and socio-demographic characteristics statistically and significantly influence their perceived ability to teach students decision-making skills. Originality/Value: The regression model was the first of its kind to investigate the influence of teacher characteristics on this particular outcome. Therefore, results provide novel but preliminary insight into teachers' perceptions.

مستخلص: Purpose: We sought to determine the perceived importance and development of agricultural students' employability skills, and the factors and experiences that influence their development. Design/Methodology/Approach: We used a cross-sectional survey research design and conducted a census of Texas A&M University College of Agriculture and Life Sciences students by distributing a researcher-developed instrument to all students following the tailored design method. We collected 991 usable responses. Findings: Students believed communication and decision-making skills were most important, but their teamwork skills and self-management skills were most developed. Seven types of professional experiences significantly and positively influenced students' perceived development of employability skills. Students who knew the type of career they wanted to pursue believed their employability skills were statistically significantly better developed than students who did not. Practical implications: Agricultural educators should help students identify career interests early in their academic pursuit and encourage their participation in professional experiences to improve their perceived employability skills development. Theoretical implications: Increased frequency of participating in teamwork, leadership, project management, community engagement, cross-disciplinary, international, and internship experiences can increase agricultural students' perceived general human capital. Knowledge regarding the type of career they want to pursue can also increase perceived human capital. Originality/Value: We identified novel characteristics of agricultural students across academic departments and at varying levels of their degree program.

الوصف: The lower lignin content in plants species with energy potential results in easier cellulose breakdown, making glucose available for ethanol generation. However, higher lignin levels can increase resistance to insect attack. The objective of this work was to evaluate the susceptibility of a bmr-6 biomass sorghum (a mutant genotype with a lower concentration of lignin) to important pests of energy sorghum, Diatraea saccharalis and Spodoptera frugiperda. Experiments were performed in the laboratory and greenhouse to evaluate the development of these pests on the biomass sorghum bmr hybrids BR007, BR008, and TX635 and their respective conventional near-isogenic genotypes (without the bmr gene). The lignin content was higher in non-bmr hybrids, but the evaluated insect variables varied between treatments, not being consistent in just one hybrid or because it is bmr or not. The lowest survival of S. frugiperda was observed in the BR008 hybrid, both bmr and non-bmr. The S. frugiperda injury scores on plants in the greenhouse were high (>7) in all treatments. For D. saccharalis, there was no difference in larval survival in the laboratory, but in the greenhouse, the BR007 hybrid, both bmr and non-bmr, provided greater survival. Due the need to diversify the energy matrix and the fact that greater susceptibility of the bmr hybrids to either pests was not found in this study, these results hold promise for cultivation of these biomass sorghum hybrids for the production of biofuels.

الوصف: The snow water equivalent (SWE) is the amount of water contained in a snow pack and is, therefore, an important variable for hydrological and climate models. Differential interferometric synthetic aperture radar (DInSAR) techniques can relate the interferometric phase of two repeat-pass SAR acquisitions to the SWE change between them. However, only a limited interval of SWE change can be retrieved unambiguously due to phase wraps of the interferometric phase. This interval strongly depends on the wavelength of the radar wave. Additional information, for instance ground measurements of SWE, is required to identify whether the SWE change exceeded that interval and to correct the phase wraps. In the study, the performance of X-, C-, and L-bands spaceborne SAR acquisitions for SWE estimation is analyzed, demonstrating the advantages and limitations of different frequencies. Shorter wavelengths show a higher accuracy for SWE estimations, while longer wavelengths are less affected by phase wraps. A multifrequency approach is proposed where L-band acquisitions are used to correct the phase wraps in the C-band SWE retrieval. The accuracy decreases slightly, but this approach allows a more robust SWE retrieval without the need of additional ground measurements. For current spaceborne SAR missions, temporal decorrelation and phase calibration are limiting factors.

الوصف: The objective of this study was to evaluate sorghum hybrids associated or not associated with Azospirillum brasilense and nitrogen fertilization (N) during planting on the yield, fermentative profile, and nutritional value of the respective silages. Five sorghum hybrids (Volumax, 201813B, 201814B, 201709B, BRS716) were evaluated with three nitrogen fertilization strategies using urea (100 kg ha−1 of N) and Azospirillum brasilense, and urea (100 kg ha−1 of N)/A. brasilense in association. A randomized block design was used in a 5 × 3 factorial scheme, with five hybrids, three fertilization strategies and three replications (blocks). The useful area of each experimental unit was 3 m x 3 m. The biomass sorghum hybrids showed a dry matter (DM) production (P = 0.01) 48.31% higher than the DM production of the Volumax forage (mean of 17.49 t ha−1 of dry matter). There was no difference between the sorghum hybrid silages in the pH values (mean of 4.11; P = 0.68), gas losses (mean of 3.74% of DM; P = 0.19). The sorghum hybrids biomass 201709B and BRS 716 showed better digestible and DM productivity. Azospirillum brasilense can be used as a nitrogen fertilization strategy in partial or total replacement of urea.

الوصف: The effects of fasting-mimicking diet (FMD) cycles in reducing many aging and disease risk factors indicate it could affect Alzheimer's disease (AD). Here, we show that FMD cycles reduce cognitive decline and AD pathology in E4FAD and 3xTg AD mouse models, with effects superior to those caused by protein restriction cycles. In 3xTg mice, long-term FMD cycles reduce hippocampal Aβ load and hyperphosphorylated tau, enhance genesis of neural stem cells, decrease microglia number, and reduce expression of neuroinflammatory genes, including superoxide-generating NADPH oxidase (Nox2). 3xTg mice lacking Nox2 or mice treated with the NADPH oxidase inhibitor apocynin also display improved cognition and reduced microglia activation compared with controls. Clinical data indicate that FMD cycles are feasible and generally safe in a small group of AD patients. These results indicate that FMD cycles delay cognitive decline in AD models in part by reducing neuroinflammation and/or superoxide production in the brain.

مستخلص: The purpose of our correlational, quantitative study was to determine if time spent using digital media (i.e. text messaging and social media) influences students' media writing self-perceptions (MWSPs). We measured students' perceived writing ability using the MWSP scale and their time spent using digital media with the social networking time use scale (SONTUS). Correlations between students' MWSP scores and SONTUS scores were statistically insignificant, suggesting that time spent using digital media does not negatively influence their perceived writing abilities. However, results from further analyses indicated that as students' social media use increased, so did their ability to recognise the difference between writing for social media and writing for professional publications. We also found that the more students text the more they use social media and vice versa. We present directions for future research and practice.

الوصف: ABSTRACTMicrosporidia cause disease in many beneficial insects, including honey bees, yet few pathogen control tools are available for protecting these important organisms against infection. Some evidence suggests that microsporidia possess a reduced number of genes encoding DNA repair proteins. We hypothesized that microsporidia would thus be susceptible to treatment with DNA-damaging agents and tested this hypothesis using a novel, rapid method for achieving robust and homogenous experimental infection of large numbers of newly emerged honey bees with one of its microsporidia pathogens, Vairimorpha (Nosema) ceranae. In carrying out these experiments, we found this novel V. ceranae inoculation method to have similar efficacy as other traditional methods. We show that the DNA-damaging agent bleomycin reduces V. ceranae levels, with minimal but measurable effects on honey bee survival and increased expression of midgut cellular stress genes, including those encoding SHSP. Increased expression of UpdlC suggests the occurrence of epithelial regeneration, which may contribute to host resistance to bleomycin treatment. While bleomycin does reduce infection levels, host toxicity issues may preclude its use in the field. However, with further work, bleomycin may provide a useful tool in the research setting as a potential selection agent for genetic modification of microsporidia.IMPORTANCEMicrosporidia cause disease in many beneficial insects, yet there are few tools available for control in the field or laboratory. Based on the reported paucity of DNA repair enzymes found in microsporidia genomes, we hypothesized that these obligate intracellular parasites would be sensitive to DNA damage. In support of this, we observed that the well-characterized DNA damage agent bleomycin can reduce levels of the microsporidia Vairimorpha (Nosema) ceranae in experimental infections in honey bees. Observation of slightly reduced honey bee survival and evidence of sublethal toxicity likely preclude the use of bleomycin in the field. However, this work identifies bleomycin as a compound that merits further exploration for use in research laboratories as a potential selection agent for generating genetically modified microsporidia.
