Effects of Principals’ Provision of Teaching and Learning Materials on Students’ Perfomance in Mathematics in Kenya Certificate of Secondary Education in Meru County

In the past few years, Mathematics performance among secondary school learners in Meru County has been decreasing. The current study aims to evaluate various administrative strategies used by principals and their effects on learners’ grade attainment in Kenya Certificate of Secondary Educationin Meru County. The study examines ways through which principals support mathematics teachers through trainings, seminars, workshops and how the support is translated into students’ performance. The study adopted ex post facto design to collect data and analyze the information for conclusion. The researcher analyzed KCSE data over the previous 5 years in Meru County, interviewed the principals, and designed questionnaire for Mathematics teachers. A total of 836 Mathematics teachers and 299 principals across the county were targeted.Using stratified and random sampling, only 251 Mathematics teachers and 92 principals were engaged, which accounts for only 30% of the target. The researcher used split half technique to test reliability and instrument piloting to ensure validity of the data. The study concluded that principals provided little support to Mathematics teachers to attend seminars and workshops. However, principals defended this by citing low resource budget allocations and inadequate resources to support teachers’ seminars and workshops. The findings of the current study can be used by education ministry, school administrator, teachers, and other stakeholders during the decision-making.

Plan for The Efficient Use and Saving of Water at The Universidad del Norte

Portable water is an essential resource for living, currently there is enough water in the world for this, but its distribution is not adequate in different places or at different seasons of the year. Climatic variations affect the water supply capacity generate economic, social and environmental problems. The commitment of Universidad Del Norte with the environment and its transversally in its missionary functions of teaching, research, and extension crystallize in academic and administrative strategies, complying not only with environmental legislation, but also management with criteria of resource efficiency (Water, energy, air, waste, fauna and flora) promoting environmental education, conservation, respect for nature and long-term sustainability. The foregoing derives from the responsibility that Universidad Del Norte has had with the community in creating a PUEAA - Plan for the efficient use and saving of water, which describes the strategies aimed at the conservation and use of water resources. The following article describes the strategies that the Universidad Del Norte carries out to have a continuous supply of water, guarantee the quality of drinking water for its consumption processes, treat all wastewater resulting from its processes, and finally reuse all water that is finally use in campus gardens.

Applications of Nanovaccines for Disease Prevention in Cattle

Vaccines are one of the most important tools available to prevent and reduce the incidence of infectious diseases in cattle. Despite their availability and widespread use to combat many important pathogens impacting cattle, several of these products demonstrate variable efficacy and safety in the field, require multiple doses, or are unstable under field conditions. Recently, nanoparticle-based vaccine platforms (nanovaccines) have emerged as promising alternatives to more traditional vaccine platforms. In particular, polymer-based nanovaccines provide sustained release of antigen payloads, stabilize such payloads, and induce enhanced antibod- and cell-mediated immune responses, both systemically and locally. To improve vaccine administrative strategies and efficacy, they can be formulated to contain multiple antigenic payloads and have the ability to protect fragile proteins from degradation. Nanovaccines are also stable at room temperature, minimizing the need for cold chain storage. Nanoparticle platforms can be synthesized for targeted delivery through intranasal, aerosol, or oral administration to induce desired mucosal immunity. In recent years, several nanovaccine platforms have emerged, based on biodegradable and biocompatible polymers, liposomes, and virus-like particles. While most nanovaccine candidates have not yet advanced beyond testing in rodent models, a growing number have shown promise for use against cattle infectious diseases. This review will highlight recent advancements in polymeric nanovaccine development and the mechanisms by which nanovaccines may interact with the bovine immune system. We will also discuss the positive implications of nanovaccines use for combating several important viral and bacterial disease syndromes and consider important future directions for nanovaccine development in beef and dairy cattle.

Antibiotic Dispensation without a Prescription Worldwide: A Systematic Review

Antibiotic resistance still remains a major global public health problem and the dispensing of antibiotics without a prescription at community pharmacies is an important driver of this. MEDLINE, Pubmed and EMBASE databases were used to search and identify studies reporting the dispensing of non-prescribed antibiotics in community pharmacies or drugstores that sell drugs for human use, by applying pharmacy interviews/questionnaires methods and/or simulated patient methods. Of the 4683 studies retrieved, 85 were included, of which 59 (69.4%) were published in low-and middle-income countries. Most of the papers (83.3%) presented a percentage of antibiotic dispensing without a prescription above 60.0%. Sixty-one studies evaluated the active substance and the most sold antibiotics without a prescription were amoxicillin (86.9%), azithromycin (39.3%), ciprofloxacin (39.3%), and amoxicillin-clavulanic acid (39.3%). Among the 65 articles referencing the diseases/symptoms, this practice was shown to be mostly associated with respiratory system problems (100.0%), diarrhea (40.0%), and Urinary Tract Infections (30.8%). In sum, antibiotics are frequently dispensed without a prescription in many countries and can thus have an important impact on the development of resistance at a global level. Our results indicate the high need to implement educational and/or regulatory/administrative strategies in most countries, aiming to reduce this practice.

Folklore of Operational Banality

This article explores the reductive workings of policy that lead to intimate everyday forms of violence within US-based medical administration. Using the framework of folklore of operational banality (“FOOB”), the article examines a geodata-driven way of addressing uncompensated medical care that targets “superusers” of the US health care system. The case scrutinizes the operative truths, procedural rationalities, and absurd reductions performed by this administrative system that sorts people in terms of cost and risk. It shows how such administrative strategies result in further bureaucratized inequities and harm, even as they claim to support life by ontologizing cost efficiency and cost-benefit thinking, accumulating biological data for geosurveillance and biosecurity, and treating risk and vulnerability as the property and responsibility of certain individuals/bodies and spaces rather than as the result of social-environmental problems. A parodic counterfigure appears in the case to amplify criticism of the individualized management of life/risk and the reliance on technocratic methods and biomedical models to define and allocate health care as separate from environmental and justice-oriented concerns. The figure of Health Coach App renders absurd the power relations of health interventions that exclude broader social etiologies of disease and illness and shows that collaborative approaches between environmental and medical humanities are needed to reveal banal administrative violence and to advocate for better policies.

Administrative Strategies For Effective Teaching In Basic Education In The Era Of Frozen Moment In Rivers State, Nigeria

The study explored administrative strategies for effective teaching in basic schools in the era of frozen moment in Rivers State, Nigeria. Three research questions were answered while three hypotheses were tested. The study adopted an analytic survey research design with a population of 247 headteachers in 247 public basic schools in Rivers State. The sample size is 172 headteachers representing 70% of the population of the headteachers. The sample size was arrived at using proportionate stratified random sampling technique. An instrument titled Administrative Strategies for Effective Teaching Scale (ASETS) was used for data collection. Face and content validities were ensured by experts in Educational Management as well as Test and Measurement in the University of Port Harcourt. The internal consistency reliability coefficient of 0.83 was computed for ASETS through Cronbach alpha statistical method. Mean and standard deviation were used to answer the research questions while z-test was used to test the hypotheses at 0.05 level of significance. It was found that the headteachers can use reward management system as well as online supervision of their teachers’ academic preparation progress to enhance their teaching effectiveness. It was also found that the headteachers have the problem of time management and financial incapacity to carry out online administrative functions. It was recommended among others that the headteachers and local and state governments should assist the teachers in procuring electronic gadgets by giving them soft loans. The headteachers should cultivate the attitude of making use of online platform to disseminate information to the teachers for teaching effectiveness.

Modeling and Prediction of COVID-19 Outbreak in India

As the outbreak of coronavirus disease 2019 (COVID-19) is continuously increasing in India, so epidemiological modeling of COVID-19 data is urgently required for administrative strategies. Time series and is capable to predict future observations by modeling the data based on past and present data. Here, we have modeled the epidemiological COVID-19 Indian data using various models. Based on the collected COVID-19 outbreak data, we try to find the propagation rule of this outbreak disease and predict the outbreak situations in India. For India data, the time series model gives the best results in the form of predication as compared to other models for all variables of COVID-19. For new cases, new deaths, total cases and total deaths, the best fitted ARIMA models are as follows: ARIMA(0,2,3), ARIMA(0,1,1), ARIMA(0,2,0) and ARIMA(0,2,1). Based on time series analysis, we predict all variables for next month and conclude that the predictive value of Indian COVID-19 data of total cases is more than 20 lakhs with more than 43 thousand total deaths. The present chapter recommended that a comparison between various predictive models provide the accurate and better forecast value of the COVID-19 outbreak for all study variables.

Iberia

A deep history of Iberia examines the waves of conquest and cultural developments on the Iberian peninsula. Agriculture was imported to Iberia from the Fertile Crescent region of Southwest Asia and included animal husbandry and the use of pack animals. Autonomous cultural developments of native Iberians were stimulated by maritime powers that sailed west along the Mediterranean: the Phoenicians, Greeks, Carthaginians, and Romans, each growing in their imperial reach and providing a base for later political and economic developments. Iberians also took advantage of their geographical setting on a peninsular hinge between the Mediterranean and Atlantic worlds, which connected two major maritime spheres of interaction and saw the development of hybrid ships increasingly suited to open ocean crossing. Following the collapse of imperial Rome, Iberia fluctuated between Christian and Islamic rule, with the former emerging victorious after a centuries-long program of national unification known as the Reconquista, or “reconquest.” Crops introduced by Muslims and administrative strategies implemented by Christian kingdoms in frontier regions were direct predecessors of the plantation-like economies eventually imposed on the Americas.
