“This Is Fine”: The Principal’s Role in the Induction Experiences of a Gay, Novice, ELA Teacher

While there have been numerous studies of teachers’ lived experiences, the LGBTQ+- teaching community continues to be underrepresented within this literature (Mayo, 2008). More specifically, empirical evidence regarding LGBTQ+ preservice teachers’ (PST) experiences and their induction is nearly all, but absent. This is of great importance to discussions and formations of educational practice and policies. Drawn from a larger, critical narratological study examining lesbian, gay, and/or queer first-year E/LA teachers, this study illuminates the experiences of a first-year, middle school E/LA teacher and her stories of her interactions with her building’s principal. Utilizing systems of first year teaching (Strom et al., 2018), tenets of queer theory (Butler, 1997), and subjectivities (Cammack & Phillips, 2002), this study drew on multiple semi-structured interviews, ethnographic field observations, preservice field experience journals and coursework, along with artifacts of student learning. Findings demonstrate the participant’s sense of space and place within her building, district, and the state, in combination with multiple interactions with her school’s administration, elicited and reified feelings of precarity, which were interwoven within her induction stories. Most importantly, these tensions affected the participant’s sense-making, and contributed to troubles with enacting more engaging, student-centered pedagogical practices, which contributed to difficulties in curating healthier classroom ecologies. Altogether, this furthered the participant’s feelings of confusion, isolation, and inefficacy. As these emotions are often associated with teacher attrition, implications center the key role principals and school policies play within teacher induction, but especially in disrupting inequities and affirming LGBTQ+ teachers’ importance within their schools.
Antiracism Education Activism: A Theoretical Framework for Understanding and Promoting Racial Equity

Although antiracism activism has contributed to substantive progress under certain circumstances and in certain contexts, little research attempts to theorize how antiracism activism is manifest across contexts. In this article, we explore individual and collective antiracist actions within and outside schools. We introduce a theoretical framework that identifies four domains of activism—policy, community, leadership, and teaching and learning—in which activists operate to make a positive difference in promoting racial equity and antiracism in education. The framework offers a systemic way of thinking about antiracist activism in education and the importance of recognizing that several aspects of antiracist activism usually conceived as distinct are interrelated within and across domains. Indeed, antiracist education activism must be understood holistically and systemically if we seek to dismantle the racism that is woven into every piece of the education system.
Some Integrals Involving Meijer’s and Hypergeometric Functions Using the Coherent State Technique

In this paper, we have examined a particular case of coherent states, defined so that their structure constants depend only on the products of the energy eigenvalues of the examined systems. In this manner, we have built all three kinds of coherent states (Barut–Girardello, Klauder–Perelomov, and Gazeau–Klauder). From the equation of the unitary operator decomposition, we have highlighted and used a so-called fundamental integral, to obtain some new integrals involving Meijer’s and hypergeometric functions. All calculations are made using the properties of the diagonal operator ordering technique. This is implicitly proved that the coherent state technique can be useful not only in different branches of physics (quantum mechanics, quantum optics, quantum information theory, and so on) but also in the deduction of new integrals involving generalized Meijer’s and hypergeometric functions. This approach can be considered as suitable “feedback” from physics to mathematics.
Exact decay and tunnelling dynamics of interacting few-boson systems

The decay and tunnelling dynamics of repulsive few-boson systems through a one-dimensional potential barrier is studied from first principles. To this end, we solve the numerically exact time-dependent few-boson Schrödinger equation by utilizing the successful multiconfiguration time-dependent Hartree method. Benchmark results for a wide range of interactions are reported. Deviations from the time-dependent Gross–Pitaevskii approach are identified. Counterintuitively, the mean-field approach can overestimate the tunnelling times even for relatively weakly-interacting few-boson systems. Implications are discussed.
Environmental Exposure to Metals, Parameters of Oxidative Stress in Blood and Prostate Cancer: Results from Two Cohorts

We studied the potential role of exposure to various metal(oid)s (As, Cd, Cr, Hg, Ni, and Pb) in prostate cancer. Two cohorts were established: the Croatian cohort, consisting of 62 cases and 30 controls, and the Serbian cohort, consisting of 41 cases and 61 controls. Blood/serum samples were collected. Levels of investigated metal(oid)s, various parameters of oxidative stress, and prostate-specific antigen (PSA) were determined in collected samples. A comparison of the measured parameters between 103 prostate cancer patients and 91 control men from both Croatian and Serbian cohorts showed significantly higher blood Hg, SOD, and GPx levels and significantly lower serum SH levels in prostate cancer patients than in controls. Correlation analyses revealed the significant relationship between certain parameters of oxidative stress and the concentrations of the measured metal(loid)s, pointing to the possible role of metal(oid)-induced oxidative stress imbalance. Furthermore, a significant inverse relationship was found between the blood Pb and the serum PSA in prostate cancer patients, but when the model was adjusted for the impacts of remaining parameters, no significant association between the serum PSA and the measured parameters was found. The results of the overall study indicate a substantial contribution of the measured metal(loid)s to the imbalance of the oxidant/antioxidant system. Although somewhat conflicting, the results of the present study point to the possible role of investigated metal(oid)s in prostate cancer, especially for Hg, since the obtained relationship was observed for both cohorts, followed by the disturbances in oxidative stress status, which were found to be correlated with Hg levels. Nevertheless, further studies in larger cohorts are warranted to explain and confirm the obtained results.
Modeling epidemic growth curves using nonlinear rational polynomial equations: an application to Brazil's COVID-19 data

This paper reports a broad study using epidemic-related counting data of COVID-19 disease caused by the novel coronavirus BARS-CoV-2). The considered dataset refers to Brazil's daily and accumulated counts of reported cases and deaths in a fixed period (from January 22 to June 16, 2020). For the data analysis, it has been adopted a nonlinear rational polynomial function to model the mentioned counts assuming Gaussian errors. The least squares method was applied to fit the proposed model. We have noticed that the curves are still increasing after June 16, with no evidence of peak being reached or decreasing behavior in the period for new reported cases and confirmed deaths by the disease. The obtained results are consistent and highlight the adopted model's capability to accurately predict the behavior of Brazil's COVID-19 growth curve in the observed time-frame.
Information entropy and dark energy evolution

Here, the information entropy is investigated in the context of early and late cosmology under the hypothesis that distinct phases of universe evolution are entangled between them. The approach is based on the entangled state ansatz, representing a coarse-grained definition of primordial dark temperature associated to an effective entangled energy density. The dark temperature definition comes from assuming either Von Neumann or linear entropy as sources of cosmological thermodynamics. We interpret the involved information entropies by means of probabilities of forming structures during cosmic evolution. Following this recipe, we propose that quantum entropy is simply associated to the thermodynamical entropy and we investigate the consequences of our approach using the adiabatic sound speed. As byproducts, we analyze two phases of universe evolution: the late and early stages. To do so, we first recover that dark energy reduces to a pure cosmological constant, as zero-order entanglement contribution, and.
Quel indice pour mesurer l’efficacité en segmentation de textes?

L’évaluation de l’efficacité d’algorithmes de segmentation thématique est généralement effectuée en quantifiant le degré d’accord entre une segmentation hypothétique et une segmentation de référence. Les indices classiques de précision et de rappel étant peu adaptés à ce domaine, WindowDiff (Pevzner, Hearst, 2002) s’est imposé comme l’indice de référence. Une analyse de cet indice montre toutefois qu’il présente plusieurs limitations. L’objectif de ce rapport est d’évaluer un indice proposé par Bookstein, Kulyukin et Raita (2002), la distance de Hamming généralisée, qui est susceptible de remédier à celles-ci. Les analyses montrent que celui-ci conserve tous les avantages de WindowDiff sans les limitations. De plus, contrairement à WindowDiff, il présente une interprétation simple puisqu’il correspond à une vraie distance entre les deux segmentations à comparer.
Pilot Study and Data Examination for the Teaching Composition of Higher Order Thinking Skills (HOTs) in the Field of Sirah on Islamic Education Teachers

A quality study requires a neat and demanding methodology for a pilot study to be conducted first and a regular examination of the data before an actual study. This paper would like to look at the findings from the pilot study and the results of the data examination on the methodology used in quantitative methods. In this study, the researcher conducted two pilot studies on 63 teachers of Islamic Education (GPI) and then analyzed data examination using SPSS 20.0. A pilot study is an essential thing before doing an actual study. However, examining the data in the pilot study analysis is an equally important matter rarely presented in any of the study articles. Therefore, this paper would like to reveal a little about the examination of data after the pilot study was conducted. The results of this study showed that the mean of the questionnaire was at a high and moderate level. While the test against the examination of the data was at a high internal consistency of the construct, typically scattered, the variables were found to be positive. Thus, actual field research can be carried out optimally.
In-silico Designing and Evaluation of gRNA for the
CRISPR/Cas9 system against the Genes associated with
Tuberculosis

Tuberculosis caused by the bacterium Mycobacterium tuberculosis has been seen to show resistance against the prescribed drugs which are of uttermost importance and act as a first line of defense. The emergence of drug resistance has become a serious concern for the society and need for new and effective armamentarium persists. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR-associated nuclease 9 (Crispr Cas9) is like a boon for the genetic engineering and have a wide application in gene editing. In the Mycobacterium tuberculosis, the gene Rv3378c is responsible for the production of a protein “ 1-TbAd ” which helps the bacterium to survive inside the host for a period. The alteration in the gene Rv3378c can be potential therapeutics for the treatment of Tuberculosis. In the present study, a guide RNA (gRNA) was designed using CRISPOR tool to perform the necessary gene editing in the bacterium. The most suitable gRNA was selected with zero off targets. Zero off targets are necessary to decrease the chances of mistake in cutting the target sequence. This technique could serve as an important armamentarium to serve and save the people suffering from this disease.
The Etiology and Management of Dental Implant Failure: A Review

As the world is embracing technology, dental technology is merging with artificial intelligence. Dentists are striving to perfect the art of placing dental implants. Implants for the rehabilitation and retention of dental and facial prostheses have graduated from a phase of wishful thinking to one of the most gratifying experiences for patients and treating fraternity alike. Implants and restorations supported by implants have a good long-term survival percentage. Complications and implant failure, which can still happen, are seen by many clinicians as significant barriers to implant treatment. Implant therapy still involves a biological healing and integration process despite recent advancements. These biological processes are complex and may be hampered by local or systemic factors, which could result in problems and implant failure. For the implant surgeon and dental professional, it is crucial to manage patients who have certain risk factors and be able to address potential complications and failure. The aim of this article is to discuss frequent complications of implant failure and its management and help clinicians in placing and restoring implants less painfully and vicariously receive some valuable experience.
The Potential of Using an Autogenous Tendon Graft by Injecting Bone Marrow Aspirate in a Rabbit Meniscectomy Model

Bone marrow aspirate (BMA) is an excellent source of cells and growth factors and has been used successfully for bone, cartilage, and soft-tissue healing. This study aimed to investigate the histological and biomechanical properties of autogenous tendon graft by injecting BMA and its protective effect against degenerative changes in a rabbit model of meniscal defects. Adult white rabbits were divided into untreated, tendon, and tendon + BMA groups, and meniscal defects were created in the knees. The tendon graft and articular cartilage status were evaluated by macroscopic and histological analysis at 4, 12, and 24 weeks postoperatively among the three groups. The tendon graft in the tendon and tendon + BMA groups were used for biomechanical evaluation at 4, 12, and 24 weeks postoperatively. The meniscal covering ratio in the tendon + BMA group was better than that in the tendon and untreated groups at 12 and 24 weeks postoperatively. The matrix around the central portion of cells in the tendon + BMA group was positively stained by safranin O and toluidine blue staining with metachromasia at 24 weeks. The histological score of the tendon graft in the tendon + BMA group was significantly higher than that in the untreated and tendon groups at 12 and 24 weeks postoperatively. In the tendon + BMA group, cartilage erosion was not shown at 4 weeks, developed slowly, and was better preserved at 12 and 24 weeks compared to the untreated and tendon groups. Histological scores for the articular cartilage were significantly better in the tendon + BMA group at 24 weeks. The compressive stress on the tendon graft in the tendon + BMA group was significantly higher than that in the tendon group at 12 weeks postoperatively. Transplantation of autogenous tendon grafts by injecting BMA improved the histologic score of the regenerated meniscal tissue and was more effective than the tendon and untreated group for preventing cartilage degeneration in a rabbit model of massive meniscal defects.
A sociophonetic account of gradient /z/ devoicing among Chicanx high schoolers

Abstract This paper examines final /z/ devoicing among Chicanx teens in Southern California to investigate the degree to which devoiced final /z/ neutralizes with final /s/ in this dialect. Results indicate on the one hand that devoiced /z/ remains distinct from /s/: as expected, devoiced /z/ is significantly less voiceless than /s/ and has a significantly lower center of gravity (COG). However, unexpectedly, devoiced /z/ has a significantly longer fricative duration and a significantly shorter preceding vowel duration than /s/, a pair of results that run counter to general tendencies for voiced fricatives to be shorter and have longer preceding vowels than their voiceless counterparts. We propose that these durational findings may explain, at least in part, the salience of final /z/ devoicing in Latinx Englishes despite its ubiquity among speakers of mainstream US English. In this first instrumental sociophonetic account of final /z/ devoicing in Latinx Englishes, we also find that, counter to existing segmental accounts, the morphological status of /z/ is no longer a significant predictor of devoicing. Moreover, while both following segment and speaker gender are significant predictors of devoicing, they do not condition devoicing in the expected ways.
Robust Emission Reduction Strategies under Cap-and-Trade and Demand Uncertainty

In this study, we consider robust emission reduction strategies for a monopolistic manufacturer facing demand uncertainty under governments’ cap-and-trade regulations. We model the manufacturer’s decision making and associated profits under four different emission reduction strategies: no mitigation measure, undertaking remanufacturing, improving the greening level, and both remanufacturing and improving the greening level. We find that the cap-and-trade regulation enhances the manufacturer’s motivation to be engaged in reducing carbon emissions. Furthermore, the manufacturer’s optimal choice of emissions reduction strategy depends on the level of carbon trading price and the degree of demand uncertainty. Specifically, there exists a threshold of carbon trading price at which the manufacturer’s optimal emissions reduction strategy will change. When the carbon trading price is low (below the threshold), the best strategy for the manufacturer to reduce emissions is to improve the greening level of the products. When the carbon trading price is high (above the threshold), the manufacturer should consider both remanufacturing and improving the greening level. Moreover, the threshold of the carbon trading price is further impacted by the demand uncertainty. With market demand uncertainty rising, the threshold of carbon trading price increases as well. Finally, we find raising the carbon trading price may not necessarily benefit the environment. Overpriced carbon trading may hurt the manufacturer’s production instead of encouraging them to take emission reduction measures.
High‐Frequency Electrostatic Waves Modulated by Whistler Waves Behind Dipolarization Front

Both the whistler waves and high‐frequency electrostatic waves (HFEWs), playing significant roles in energy conversion, have been widely studied behind dipolarization fronts (DFs). Nevertheless, interactions between them have been so far elusive. Utilizing high‐resolution MMS data, we present two cases that HFEWs were modulated by whistler waves behind a DF. The HFEWs with frequency at fce ∼ fpe, propagating along the ambient magnetic field, were detected near δE// minimum (maximum) of parallel‐propagating (antiparallel‐propagating) whistler waves. The amplitudes of the HFEWs are comparable to that of the whistler waves, while their energy densities are two orders of magnitude lower than that of the whistler waves. The analysis indicates that the whistler waves were locally excited by anisotropic electron distributions and the HFEWs were excited by electron beams produced by the whistler waves via Landau resonance. Our study advances the understanding of wave‐wave interactions and cross‐scale processes in space plasmas.
Detecting Malware by Analyzing App Permissions on Android Platform: A Systematic Literature Review

Smartphone adaptation in society has been progressing at a very high speed. Having the ability to run on a vast variety of devices, much of the user base possesses an Android phone. Its popularity and flexibility have played a major role in making it a target of different attacks via malware, causing loss to users, both financially and from a privacy perspective. Different malware and their variants are emerging every day, making it a huge challenge to come up with detection and preventive methodologies and tools. Research has spawned in various directions to yield effective malware detection mechanisms. Since malware can adopt different ways to attack and hide, accurate analysis is the key to detecting them. Like any usual mobile app, malware requires permission to take action and use device resources. There are 235 total permissions that the Android app can request on a device. Malware takes advantage of this to request unnecessary permissions, which would enable those to take malicious actions. Since permissions are critical, it is important and challenging to identify if an app is exploiting permissions and causing damage. The focus of this article is to analyze the identified studies that have been conducted with a focus on permission analysis for malware detection. With this perspective, a systematic literature review (SLR) has been produced. Several papers have been retrieved and selected for detailed analysis. Current challenges and different analyses were presented using the identified articles.
The X-Ray Binary Population of the Nearby Dwarf Starburst Galaxy IC 10: Variable and Transient X-Ray Sources

We have monitored the Cassiopeia dwarf galaxy (IC 10) in a series of 10 Chandra ACIS-S observations to capture its variable and transient X-ray source population, which is expected to be dominated by High Mass X-ray Binaries (HMXBs). We present a sample of 21 X-ray sources that are variable between observations at the 3σ level, from a catalog of 110 unique point sources. We find four transients (flux variability ratio greater than 10) and a further eight objects with ratios >5. The observations span the years 2003–2010 and reach a limiting luminosity of >1035 erg s−1, providing sensitivity to X-ray binaries in IC 10 as well as flare stars in the foreground Milky Way. The nature of the variable sources is investigated from light curves, X-ray spectra, energy quantiles, and optical counterparts. The purpose of this study is to discover the composition of the X-ray binary population in a young starburst environment. IC 10 provides a sharp contrast in stellar population age (<10 My) when compared to the Magellanic Clouds (40–200 My) where most of the known HMXBs reside. We find 10 strong HMXB candidates, 2 probable background Active Galactic Nuclei, 4 foreground flare-stars or active binaries, and 5 not yet classifiable sources. Complete classification of the sample requires optical spectroscopy for radial velocity analysis and deeper X-ray observations to obtain higher S/N spectra and search for pulsations. A catalog and supporting data set are provided.
