Educator diversity and student accomplishment

There are many factors that contribute to a student’s academic and personal performance within the context of their PK-12 Education. Independent of atypical developmental abilities, family wealth is a significant factor in student performance. Other factors, endogenous to what happens within school, include community resources, with a particular focus on sustained financial support for schools. Although the overall performance of a particular school is driven by the relative wealth of the students in the school, the level of language proficiency among students within the school, and the percentage of special needs students in the classroom and building, the variation of performance between schools with similar populations is driven by the effectiveness of the educators in the building (Opper, 2019). If we are going to close the various achievement gaps that plague our educational systems, a focus on how to prepare, recruit, and retain highly effective educators, particularly within our high needs and culturally diverse schools, is a national imperative.Accepted manuscrip

Effect of goat weed leaf meal (Ageratum conyzoides) as a partial dietary replacement for maize in the diet of African catfish (Clarias gariepinus)

It is crucial to find ways to employ less expensive conventional materials in fish farming to lower production costs without adversely affecting the general performance of the fish. Consequently, certain neglected plants, such as goat weed leaves that have been reported to have the potential to serve as a partial substitute for maize (energy source) must be considered. Therefore, this research evaluated the effects of partially replacing maize with goat weed leaf meal (Ageratum conyzoides) (GWLM) on the growth, haematology, and serum enzyme indices of Clarias gariepinus. A 56-day feeding trial was conducted with a total of 500 juveniles with an average weight of 13.7 g. After sterilizing the fish in a mixture of potassium permanganate and water to reduce stress, a one-week acclimatisation period was ensured using commercial feed (2 mm). Subsequently, the juveniles were randomly stocked in quadruplets of 25 fish per culture tank measuring 1.2 m x 1.2 m x 0.9 m each (labelled Ai-iv, Bi-iv, Ci-iv, Di-iv, and Ei-iv) based on the number of repetition and the diet to be fed. A total of five (5) different diets with varying levels of dietary inclusion (A: 0%, B: 2%, C: 4%, D: 6%, and E: 8%) of goat weed leaf meal (GWLM) as a partial replacement for maize were formulated to contain a minimum crude protein level of 40%. The test diets were administered twice daily (7:00 hrs. and 18:00 hrs.) and the sampled fish were adequately fed (5% body weight) with proper follow-up to monitor feeding behaviour. The data collected from the research were subjected to a one-way analysis of variance (ANOVA) using the SPSS version 23 analysis package. Furthermore, a Duncan multiple-range test was employed to separate the means. There were notable (p 0.05) variations in various parameters (proximate composition, digestibility of nutrients, growth performance, haematological and serological profiles, and water quality) observed in all treatments as the inclusion of the test ingredient in the diet increased. However, as the inclusion levels of the test ingredient increased above 4%, a steady decline was observed between treatments. At a 4% dietary inclusion level, the best performance indices (weight gained (36.52g), feed conversion ratio (2.15), specific growth rate (2.31) and survival rate (95%)), and blood profile (haematology and serum enzyme indices) were observed. Therefore, a 4% replacement of maize using goat weed leaf meal (GWLM) in the diet is suitable for an optimum performance of African catfish

Pharmacological Advances in Opioid Therapy: A Review of the Role of Oliceridine in Pain Management

Problems with the treatment of acute pain may arise when a patient is opioid-tolerant, such as those on chronic therapy with opioids or opiate replacement therapy, those who misuse opioids, and those who are in recovery. While some of the adverse effects of opioid medications are well known, it is also important to recognize the roles of tolerance and hyperalgesia. Oliceridine can target and modulate a novel μ-receptor pathway. The G protein-biased agonism of oliceridine allows for effective re-sensitization and desensitization of the mu-opioid receptor, which decreases the formation of opioid tolerance in patients. Oliceridine has been demonstrated to be an effective and relatively safe intravenous analgesic for the treatment of postoperative pain and is generally well tolerated with a favorable side effect profile when compared to morphine. As the prevalence of pain increases, it is becoming increasingly important to find safe and effective analgesics

Solar thermoelectricity Via Advanced Latent Heat Storage

An aspect of the present disclosure is a system that includes a thermal valve having a first position and a second position, a heat transfer fluid, and an energy converter where, when in the first position, the thermal valve prevents the transfer of heat from the heat transfer fluid to the energy converter, and when in the second position, the thermal valve allows the transfer of heat from the heat transfer fluid to the energy converter, such that at least a portion of the heat transferred is converted to electricity by the energy converter

Comparative Genomic Characterization of the Multimammate Mouse Mastomys coucha.

Mastomys are the most widespread African rodent and carriers of various diseases such as the plague or Lassa virus. In addition, mastomys have rapidly gained a large number of mammary glands. Here, we generated a genome, variome, and transcriptomes for Mastomys coucha. As mastomys diverged at similar times from mouse and rat, we demonstrate their utility as a comparative genomic tool for these commonly used animal models. Furthermore, we identified over 500 mastomys accelerated regions, often residing near important mammary developmental genes or within their exons leading to protein sequence changes. Functional characterization of a noncoding mastomys accelerated region, located in the HoxD locus, showed enhancer activity in mouse developing mammary glands. Combined, our results provide genomic resources for mastomys and highlight their potential both as a comparative genomic tool and for the identification of mammary gland number determining factors

Human involvement in autonomous decision-making systems. Lessons learned from three case studies in aviation, social care and road vehicles

This paper draws on three case studies to examine some of the challenges and tensions involved in the use of Autonomous Decision-Making Systems (ADMS). In particular, the paper highlights: (i) challenges around the shifting “locale” of the decision, and the associated consequences for stakeholders; (ii) potential implications for stakeholders from regulation such as the General Data Protection Regulation (GDPR); (iii) the different values that stakeholder groups bring to the “decision” question; (iv) how complex pre-existing webs of stakeholders and decision-making authorities may be disrupted or disempowered by the use of an automated system and the lack of evaluation of possible consequences; (v) how ADMS for non-technical users can lead to circumvention of the boundaries of intended system use. We illustrate these challenges through case studies in three domains: adult social care, aviation, and vehicle driver monitoring systems. The paper closes with recommendations for both practice and policy in the deployment of ADMS

Global warming and the cosmopolitan political conception of justice

Within the literature in green political theory on global environmental threats one can often find dissatisfaction with liberal theories of justice. This is true even though liberal cosmopolitans regularly point to global environmental problems as one reason for expanding the scope of justice beyond the territorial limits of the state. One of the causes for scepticism towards liberal approaches is that many of the most notable anti-cosmopolitan theories are also advanced by liberals. In this paper, I first explain why one of the strongest expressions of liberal anti-cosmopolitanism cannot simply be dismissed because it may fail to support desired environmental ends. The political conception of justice represents one of the most important challenges to cosmopolitanism generally and is thus a serious challenge to viewing global environmental problems in terms of cosmopolitan justice. Second, I will show through the case of anthropogenic global warming that the political conception of justice under current conditions does have clear cosmopolitan implications despite its proponents' claims

Reduced dielectric screening and enhanced energy transfer in single and few-layer MoS2

We report highly efficient non-radiative energy transfer from cadmium selenide (CdSe) quantum dots to monolayer and few-layer molybdenum disulfide (MoS2). The quenching of the donor quantum dot photoluminescence increases as the MoS2 flake thickness decreases, with the highest efficiency (>95%) observed for monolayer MoS2. This counterintuitive result arises from reduced dielectric screening in thin layer semiconductors having unusually large permittivity and a strong in-plane transition dipole moment, as found in MoS2. Excitonic energy transfer between a 0D emitter and a 2D absorber is fundamentally interesting and enables a wide range of applications including broadband optical down-conversion, optical detection, photovoltaic sensitization, and color shifting in light-emitting devices.Comment: 14 pages, 4 figure
