An Exploration of Latinx Generation Z Secondary Teachers’ Lived Experiences, Motivations, and Retention Factors to Teach in the Rio Grande Valley

Generation Z teachers have encountered pivotal events in their lives that have empowered them into becoming change agents in society. They have entered the classrooms during a time of great change in education caused by the COVID-19 pandemic and the ongoing teacher shortages in schools. Generation Z teachers have had to adapt to the changes in education and endure the challenges of transitioning back to face-to-face instruction. As school districts prepare for the post-pandemic era, it is important to capture the lived experiences of Latinx Generation Z secondary teachers to understand the motivation and retention factors that influence their decision to remain in the classroom. This qualitative phenomenological study explores three Latinx Generation Z secondary teachers’ from the Rio Grande Valley in South Texas. Through semi-structured interviews, rich descriptions of the teachers’ experiences, motivations, and retention factors are discovered. To retain and motivate the newest generational cohort of teachers, in a multigenerational workforce, district leaders may want to consider reevaluating their frameworks to increase motivation and teacher retention in the school districts. The findings reveal how important it is for district leaders to recognize the Generation Z teachers’ efforts, provide them with strong support systems and mentorships, and create a campus culture of compassion and empathy

A knowledge-based expert system for scheduling of airborne astronomical observations

The Kuiper Airborne Observatory Scheduler (KAOS) is a knowledge-based expert system developed at NASA Ames Research Center to assist in route planning of a C-141 flying astronomical observatory. This program determines a sequence of flight legs that enables sequential observations of a set of heavenly bodies derived from a list of desirable objects. The possible flight legs are constrained by problems of observability, avoiding flyovers of warning and restricted military zones, and running out of fuel. A significant contribution of the KAOS program is that it couples computational capability with a reasoning system

Sustainability of Lusaka sewage works

Lusaka, the capital city of Zambia, has a central waterborne sewerage system which was first constructed in 1956 and expanded upon in 1970 and 1980. It is currently serving more than 400,000 people which represents about 36% of the city’s population including trade effluents from industries. No major rehabilitation works have ever been carried out on this aging system over the past 15 years. In recent years, the system has experienced both operational and maintenance problems, ranging from poor management, untrained plant operators, lack of motivation among the workers and scarcity of funds. The key technical problems seriously affecting the works include: inoperative equipment such as influent flow meters, mechanical bar screens and grit chambers, reduced sewer and pump capacities, sediment build-up that block sewers and interfere with sewage pumps and frequent mechanical and electrical breakdowns. This paper highlights the main causes of these problems, the efforts that have been made to solve them and a mechanism that has been adopted in order to sustain the existing sewage works

Controlled Delivery of Sdf-1 Alpha and Igf-1: Cxcr4(+) Cell Recruitment and Functional Skeletal Muscle Recovery

Therapeutic delivery of regeneration-promoting biological factors directly to the site of injury has demonstrated its efficacy in various injury models. Several reports describe improved tissue regeneration following local injection of tissue specific growth factors, cytokines and chemokines. Evidence exists that combined cytokine/growth factor treatment is superior for optimizing tissue repair by targeting different aspects of the regeneration response. The purpose of this study was to evaluate the therapeutic potential of the controlled delivery of stromal cell-derived factor-1alpha (SDF-1 alpha) alone or in combination with insulin-like growth factor-I (SDF-1 alpha/IGF-I) for the treatment of tourniquet-induced ischemia/reperfusion injury (TK-I/R) of skeletal muscle. We hypothesized that SDF-1 alpha will promote sustained stem cell recruitment to the site of muscle injury, while IGF-I will induce progenitor cell differentiation to effectively restore muscle contractile function after TK-I/R injury while concurrently reducing apoptosis. Utilizing a novel poly-ethylene glycol PEGylated fibrin gel matrix (PEG-Fib), we incorporated SDF-1 alpha alone (PEG-Fib/SDF-1 alpha) or in combination with IGF-I (PEG-Fib/SDF-1 alpha/IGF-I) for controlled release at the site of acute muscle injury. Despite enhanced cell recruitment and revascularization of the regenerating muscle after SDF-1 alpha treatment, functional analysis showed no benefit from PEG-Fib/SDF-1 alpha therapy, while dual delivery of PEG-Fib/SDF-1 alpha/IGF-I resulted in IGF-I-mediated improvement of maximal force recovery and SDF-1 alpha-driven in vivo neovasculogenesis. Histological data supported functional data, as well as highlighted the important differences in the regeneration process among treatment groups. This study provides evidence that while revascularization may be necessary for maximizing muscle force recovery, without modulation of other effects of inflammation it is insufficient.Kinesiology and Health Educatio

Factors Associated With Poor Medication Adherence In Hypertensive Patients In Lusaka, Zambia

Objectives: To determine the prevalence of drug adherence and factors associated with poor adherence to antihypertensive treatment among adults seen in the department of medicine at UTH. To investigate patient related and health care system related factors associated with poor adherence to antihypertensive Drugs.Methods: 237 adult patients aged 18 and above with previous diagnosis of essential hypertension receiving out patient care in the University Teaching Hospital (UTH) were recruited from the first week of November to the second week of December 2010. Information was collected regarding health care system related factors and care giver related factors to patient non adherence using self report and modified Hill-Bone compliance scale.Results: The prevalence of adherence was 83% by self report and 70% using modified Hill-Bone scale. The mean age was 57.8 ± 12.0 SD. Patients on three antihypertensive drugs were less likely to be nonadherent (OR 0.21; 95% 95% CI 0.06-0.79) than patients taking only one drug. Majority (60%) of the patients were reviewed at least twice in the last 6 months at the time of the interview. 195 (83%) patients reported that drugs prescribed were not available at the hospital pharmacy, but 186 (79%) of these were able to purchase the drugs elsewhere. Patients counseled by the nurse were more likely to be adherent than those not counseled by the nurse (OR 2.7: 95% CI1.0-7.3). Those who were counseled for more than 5 minutes had three fold likelihood of less non-adherence as reported by both self report and modified Hill-Bone with OR 0.3: 95% CI 0.2-0.8 and 0.3: 95% CI 0.1-0.5, respectively. Multivariable analysis showed that; participants were more likely to be non-adherent by self-report if they had attained a primary level of education, had missed appointments due to lack of transport, or had experienced the side effect of dizziness. Patients with heart failure were more likely to be nonadherent based on the modified Hill-Bone score.Conclusion: The prevalence of adherence among hypertensive patients was found to be higher than anticipated. The factors associated with nonadherence included side effect of dizziness, missed appointment due to lack of transport, and living at a distance of more than 10 km from the hospital. Taking 3 BP drugs and receiving more than 5 minutes of counseling about how to take medications were both associated with decreased likelihood of non-adherence

Labeling Compliance and Species Authentication of Fish Fillets Sold at Grocery Stores in Southern California

Seafood mislabeling has numerous consequences, including economic deception and food safety risks. The focus of this study was to investigate fish species labeling, use of acceptable market names, and Country of Origin Labeling (COOL) compliance for fresh fish fillets sold at grocery store seafood counters in Southern California. A total of 120 fillets representing 16 different categories of fish were collected from 30 Perishable Agricultural Commodities Act (PACA)-listed grocery stores. Each sample underwent DNA barcoding to identify the species. Acceptable market names were confirmed using the FDA Seafood List. Samples were determined to be compliant with COOL if both the country of origin and the production method were declared in accordance with regulatory requirements. Species substitution was detected in 16 of the 120 samples (13.3%) and unacceptable market names were observed for an additional 11 samples (9.2%). The highest rates of species substitution were recorded for snapper (3/3), yellowtail (2/4), halibut (4/10), cod (3/10), and bass (2/7). COOL noncompliance was observed for 28 samples (23.3%): the country of origin was missing for 15 samples, production method was missing for 9 samples, and 4 samples were missing both. When all forms of mislabeling were considered, 47 of the 120 samples (39.2%) had at least one labeling error. The majority of grocery stores (25/30) had one or more samples with a mislabeling error. This study revealed species mislabeling as a continuous concern in the seafood industry, especially with higher-valued species. Furthermore, the lack of COOL compliance among retailers is concerning and suggests a need for increased focus on these regulations
