An Analysis of the Development of Middle Leaders in Chinese Secondary Schools: The Role of the Principal

Numerous studies conducted on educational leadership have generally emphasized the role of principal, whereas, research on middle leadership remains limited [1]. The purpose of this paper is to explore and investigate the development of middle leadership and seeks to fill in the gap by providing the analysis from a Chinese context. The author found that middle leaders are positioning at a challenging role, in which they are required to take charge of responsibilities of both a leader and a teacher, and in the meantime, they also need to negotiate between the senior leader, the colleagues. and subordinates. Furthermore, personal factors such as self-awareness and resilience are discovered to be pivotal for middle-leadership development. Apart from that, the principal plays a critical role in establishing collaborative school culture that facilitates the development of middle leaders based on the influences from the school’s history, culture, and policies.
The central black hole masses and Doppler factors of the gamma-ray loud blazars

In this paper, the central black hole masses and the Doppler factors are derived for PKS 0528 + 134, PKS 0537-441, 3C 279, PKS 1406 - 074, PKS 1622 - 297, Q1633 + 382, Mkn 501, and BL Lacertae. The masses obtained are in the range of (1-7) 10(7) M-. and compared with that obtained with the Klein-Nishina cross section considered (Dermer & Gehrels 1995). If we considered only the Thomson cross section, the masses are in the range of 2.6 10(6) M-. - 2 10(11) M-. The masses obtained from our method are less sensitive to the flux than those obtained from Dermer & Gehrels (1995) method. The masses obtained from two flares (1991 and 1996 flares) of 3C 279 are almost the same. For 3C 279 and BL Lacertae, viewing angle, theta, and Lorentz factor, Gamma, are estimated from the derived Doppler factor and the measured superluminal velocity. For 3C 279, theta = 10 degrees.9 -15 degrees.6, Gamma = 2.4 - 14.4 for delta = 3.37; theta=8 degrees.45 - 9 degrees.7, Gamma = 2.95 - 11.20 for delta = 4.89; for BL Lacertae, theta = 25 degrees - 29 degrees.4, Gamma = 2.0 - 4.0.
Use of Turkisms in the Register of Khutbahs in the Albanian Language

The present research deals with an important part of the Albanian lexicon known as Turkisms which has been the subject of numerous studies of the Balkan languages. Namely, this research aims at analyzing the presence and status of Turkisms in khutbahs as a specific register of the spoken language. The analysis of the use of this part of the Albanian lexicon is done based on the theory of corpus linguistics, the theory of languages in contact and the so­ciolinguistic approach to language varieties. The study relies on the linguistic multifunctionality and pluralism, on the basis of which we claim that the use of Turkisms in different registers and styles disables their replacement with Albanian words. The study was conducted in search of the answer to the ques­tion: Have Turkisms shifted from formal to in-formal registers?
Exploring loss and grief during the COVID-19 pandemic: A scoping review of qualitative studies.

INTRODUCTION The COVID-19 pandemic has brought about multiple losses to various groups, namely patients, families and healthcare professionals. Grief, which is the reaction to these losses, could cause strain on these individuals' physical and mental health if not identified and managed early. This scoping review analysed loss, grief and how they were managed among these groups during the pandemic. METHOD This scoping review utilised the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement extension for Scoping Reviews (PRISMA-ScR) and the Joanna Briggs Institute framework for scoping reviews. Only qualitative studies relating to loss and grief and their management were included. Of 166 studies screened, 69 were included in the study. Qualitative analysis and data coding of each record were conducted through qualitative data analysis software. RESULTS Losses included the death of family members, patients, colleagues and others. They also included the loss of usual routines, lifestyles and physical health. The grief experienced was multidimensional, affecting mainly the emotional, physical, social and existential realms. Anger, guilt and fear resulted from unsatisfactory farewells, issues with funerals, social isolation, financial strain and stigmatisation. Management strategies could be categorised into 5 themes: communication, finance, counselling, education and spiritual care. CONCLUSION Loss and grief identification and management among patients, family members and healthcare professionals are critically important during this COVID-19 pandemic. Current operating guidelines have proven insufficient in managing loss and grief. Innovative strategies are essential to tackle the many dimensions of loss and grief. Nevertheless, further research is necessary to better understand the effectiveness of implemented policies.

Suppression of Background Noise in Speech Signals with Artificial Neural Networks, Exemplarily Applied to Keyboard Sounds

The importance of remote voice communication has greatly increased during the COVID-19 pandemic. With that comes the problem of degraded speech quality because of background noise. While there can be many unwanted background sounds, this work focuses on dynamically suppressing keyboard sounds in speech signals by utilizing artificial neural networks. Based on the Mel spectrograms as inputs, the neural networks are trained to predict how much power of a frequency inside a time window has to be removed to suppress the keyboard sound. For that goal, we have generated audio signals combined from samples of two publicly available datasets with speaker and keyboard noise recordings. Additionally, we compare three network architectures with different parameter settings as well as an open-source tool RNNoise. The results from the experiments described in this paper show that artificial neural networks can be successfully applied to remove complex background noise from speech signals.

Effects of nonlocal interactions in describing V centers of MgO

The electronic structure and optical absorption spectrum of V 0 and center in MgO are investigated based on the density functional theory. The V-type centers are well described when the local symmetry around Mg vacancy is destroyed by using the nonlocal hybrid functionals. It is demonstrated that the holes are trapped on one (or two) O atoms around Mg vacancy for (or V 0) center. The defect states are separated from the valence bands due to the nonlocal exchange interactions involved in the hybrid functionals, which is the key to describing the optical properties correctly. At ambient condition, the absorption peaks ∼2.5 eV and ∼2.6 eV are assigned to V 0 and center, respectively, and they exhibit blue shift with increasing pressure.
Survival Psi and Somatic Psi: Exploratory Quantitative Phenomenological Analysis of Blinded Mediums' Experiences of Communication with the Deceased and Psychic Readings for the Living.

: In this study, we quantitatively assessed mediums’ phenomenology during readings in which survival psi is ostensibly used to telepathically communicate with physically deceased targets (discarnates) and during psychic readings for living targets to represent somatic psi which cannot be experimentally demonstrated. We also correlated dimensions of phenomenology with reading accuracy. Ten Windbridge Certified Research Mediums (WCRMs) participated in a baseline assessment and then in three counter-balanced conditions—a blinded reading for a living target, a blinded reading for a deceased target, and a control condition—and completed the Phenomenology of Consciousness Inven-Julie tory (PCI) at baseline prior to the first condition and after each of the three conditions. In a significant proportion of the readings (74%; p = .032), the blinded WCRM’s impressions accurately reflected whether the target was living or deceased. Hypnoidal state scores, which estimate an individual’s ‘trance state,’ were significantly higher for each of the two reading conditions than for the baseline and control conditions. Both types of readings demonstrated significantly higher scores for the PCI (sub)dimensions of altered time sense, imagery, imagery amount, and direction of attention and lower scores for the dimension volitional control. As predicted, scores for love were significantly higher for blinded readings for deceased targets than for living targets (3.65 ± 0.63 vs. 2.75 ± 1.18, respectively; t [9] = 2.78, p = .02, two-tailed). The global accuracy scores of readings for living targets (2.38 ± 1.51) were significantly negatively correlated with imagery vividness ( r [6] = -0.76, p = .027) and absorption ( r [6] = -0.74, p = .037). The global accuracy scores given to readings for deceased targets (3.22 ± 1.56) were not significantly correlated to any PCI dimensions. However, the correlations were significantly different between the deceased target condition and the living target condition for positive affect and accuracy ( z = 1.92, p = .027 [one-tailed]). Overall, the novel quantitative evidence collected during this study under blinded, randomized, and counterbalanced conditions may reflect the general phenomenology of psi and supports and adds to the empirical comparisons of mediums’ psychic functioning and survival psi experiences.
An Imperative on Green Financing in the Perspective of Nepal

Purpose: The social imperative of Green Financing is most for saving the future. This imperative assessment focuses mostly on a new and innovative financial concept that is green financing, which is now functioning as one of the most important strategies to attain economic stability together with overall sustainable growth. Design/Methodology/Approach: The research is descriptive in nature to analyze the future prospects of global financing in reference to Nepal. Literature based review dominated conceptual research is exploratory in nature. The key informants were consulted personally. On the basis of advantages, disadvantages, status, and actions required the professionals' opinions were documented using steps recommended by grounded theory. The Focus Group Discussion among professionals other than key informants was also done after collecting data personally on the same agendas for validation of research. It is furthermore illustrated with help of Ecotourism case analysis. It could be said partial ABCD based discussion and content analysis accumulated the research. Findings/Result: Globalization is having an increasingly negative impact on the environment, it is no longer an option for industries all over the globe to achieve overall green growth by adopting various green initiatives that allow them to achieve a climate-resilient future through both environmentalism and capitalism at the same time; rather, it is now a necessity rather than an option for them to do so. the function and relevance of green financing in not just one sector but for all other industries, which can embrace this concept in one way or another for the purpose of achieving total green growth has been illustrated. Despite the fact that green financing is currently a niche concept, the application finds to be highly beneficial. Originality/Value: Both relevant and practical aspects for future financing in the form of green financing have been recognized within a broader context to create an appeal and awareness on an academic platform.

Is Neck Circumference Related to Other Anthropometric Measurements and Biochemical Parameters in Type 2 Diabetes?

Background Obesity is one of the leading risk factors for developing type 2 diabetes mellitus (T2DM). Body mass index (BMI), waist circumference, and waist/hip ratio are anthropometric measurements used to diagnose obesity. In recent years, neck circumference, one of the anthropometric indicators used in assessing obesity, has come to the fore. This study investigates the relationship between neck circumference and other anthropometric measurements and specific biochemical parameters in T2DM. Methods Four hundred sixty-four individuals with type 2 diabetes were included in the study. Subjects’ body weight, height, and other anthropometric measurements like circumferences of the waist, hip, and neck were measured. BMI, waist/hip, and waist/height ratio were calculated. The biochemical tests of the subjects in the previous month from the study were accessed from the hospital information system. The relationship between anthropometric measurements and biochemical parameters with neck circumference was evaluated. Results The mean age of the subjects was 54.6±8.51 years. 56.2% were female and 43.8% were male, and the time from T2DM diagnosis was 9.9±7.49 years. Most male subjects were overweight (49.8%), and approximately one-third of the women were first-degree obese (33.0%). Body weight, BMI, waist, hip, and neck circumferences, and waist/hip and waist/height ratios were significantly higher in both male and female subjects in the neck circumference high-risk group than those in the low-risk group (p<0.05). In terms of biochemical parameters, fasting blood glucose and HbA1c values of men with neck circumference at risk were significantly higher than those in the low-risk group. Neck circumference measurements of the participants were positively correlated with body weight (r=0.543; p<0.001), height (r=0.260; p<0.001), waist circumference (r=0.562; p<0.001), hip circumference (r=0.293; p<0.001), BMI (r=0.366; p<0.001), waist/hip ratio (r=0.428, p<0.001), and waist/height ratio (r=0.393, p<0.001). Neck circumference had a low positive correlation with fasting blood glucose (r=0.165; p<0.001), HbA1c (r=0.281; p<0.001), and triglyceride (r=0.231; p<0.001) and a negative relationship with low-density lipoprotein cholesterol (r=-0.118; p=0.001). When the relationship between neck circumference and biochemical parameters was examined, it was seen that this correlation was only in men. Conclusion Neck circumference measurement is a simple and reliable method and is not affected by external factors. It correlates with other anthropometric measurements and can be used as a good indicator of the distribution of upper subcutaneous adipose tissue in T2DM. However, more studies with larger samples are needed on this subject.
Human resource management in small and medium-sized enterprises: A performance model definition

Background: Nowadays, studying small and medium-sized companies, particularly with regard to the management of human resources that takes place in them, is particularly relevant. Effectively, knowing that about 99.8% of companies are small and medium-sized, contributing very significantly to high levels of employability, it is extremely important to understand the role that people management assumes in these organizations, as well as which are the factors, both internal and external, that exert the greatest influence on them. Purpose: In this paper we investigate internal and external factors of small business likely to correlate with a more formal and structured human resource management. Study design/methodology/approach A conceptual model was defined through the literature on human resource management and its consistency was tested through three methodological steps (exploratory interviews; readjustment of variables with the Delphi method; multivariate statistical tests). From a survey of 186 smaller firms in Portugal, we tested conceptual model by structural equation modelling. Findings/conclusions: The analysis reveals that dimensions such as organizational structure, management and communication style, career management, organizational flexibility, organizational strategy and national culture are positively related to more formal and structured human resource management practices and policies. Limitations/future research: Due to its complexity, both at the level of the conceptual analysis and the empirical level, this study presents some limitations, namely, and among others, the complexity of the number of dimensions and variables under analysis, and the complexity of the model being tested. A broader line of research could include collecting data from employee. This analysis would allow for a different perspective of the company's procedures and would broaden some issues that are less detailed in this study.
Strong Griffiths singularities in random systems and their relation to extreme value statistics

We consider interacting many-particle systems with quenched disorder having strong Griffiths singularities, which are characterized by the dynamical exponent, $z$, such as random quantum systems and exclusion processes. In several $d=1$ and $d=2$ dimensional problems we have calculated the inverse time scales, ${\ensuremath{\tau}}^{\ensuremath{-}1}$, in finite samples of linear size, $L$, either exactly or numerically. In all cases, having a discrete symmetry, the distribution function, $P({\ensuremath{\tau}}^{\ensuremath{-}1},L)$, is found to depend on the variable, $u={\ensuremath{\tau}}^{\ensuremath{-}1}{L}^{z}$, and to be universal given by the limit distribution of extremes of independent and identically distributed random numbers. This finding is explained in the framework of a strong disorder renormalization group approach when, after fast degrees of freedom are decimated out, the system is transformed into a set of noninteracting localized excitations. The Fr\'echet distribution of $P({\ensuremath{\tau}}^{\ensuremath{-}1},L)$ is expected to hold for all random systems having a strong disorder fixed point, in which the Griffiths singularities are dominated by disorder fluctuations.
Towards Noncommutative Quantum Black Holes

In this paper we study noncommutative black holes. We use a diffeomorphism between the Schwarzschild black hole and the Kantowski-Sachs cosmological model, which is generalized to noncommutative minisuperspace. Through the use of the Feynman-Hibbs procedure we are able to study the thermodynamics of the black hole, in particular, we calculate the Hawking's temperature and entropy for the noncommutative Schwarzschild black hole.
Determinants of the level of inequality and poverty in Cameroon: A multidimensional decomposition analysis

L’adoption du cadre theorique de l’approche des capabilites de SEN qui presente la pauvrete comme la privation de fonctionnements elementaires en terme de logement, sante, emploi, loisir, relations sociales et ressources economiques, associee a la theorie des ensembles flous (CERIOLI et ZANI [1990]) et a la decomposition d’inegalites par les sources (SHAPLEY-SHORROCKS [1999]), nous permet d’analyser les privations en termes d’inegalites de pauvrete au Cameroun. Les resultats de notre etude revelent que, les capabiltes humaines (instruction, logement) et les capabilites economiques (emploi, autre confort) expliquent aussi bien le niveau eleve de la pauvrete totale que celui des inegalites de la pauvrete. Ces resultats laissent presager une forte vulnerabilite de certaines categories de menages face a la pauvrete. The theoretical framework of SEN's capabilities approach presents poverty as a deprivation of elementary functioning in terms of housing, health, employment, leisure, social relations and economic resources. Association of the SEN’s approach with the fuzzy set theory (CERIOLI et ZANI [1990]) and the decomposition by sources (SHAPLEY-SHORROCKS [1999]), enables the analysis of deprivation in terms of inequality of poverty in Cameroon. From our application, we can see that in most cases, human capabilities (instruction, housing) as well as economic capabilities (employment, leisure) are those which explain the high level of total poverty. These results are substantially identical as regards the inequality of poverty. This suggests that Cameroonian households would be concern by vulnerability conditions facing poverty.
Inﬂuence of Energy Management System Control Strategies on the Battery State of Health in Hybrid Electric Vehicles

: Nowadays, the automotive market has showed great interest in the diffusion of Hybrid Electric Vehicles (HEVs). Despite their low emissions and energy consumptions, if compared with traditional fossil fuel vehicles, their architecture is much more complex and presents critical issues in relation to the combined use of the internal combustion engine (ICE), the electric machine and the battery pack. The aim of this paper is to investigate lithium-ion battery usage when coupled with an optimization-based strategy in terms of the overall energy management for a speciﬁc hybrid vehicle. A mathematical model for the power train of a Peugeot 508 RXH was implemented. A rule-based energy management system (EMS) was developed and optimized using real data from the driving cycles of two different paths located in Messina. A mathematical model of the battery was implemented to evaluate the variation of its voltage and state of charge (SOC) during the execution of driving cycles. Similarly, a mathematical model was implemented to analyze the state of health (SOH) of the battery after the application of electrical loads. It was thus possible to consider the impact of the energy management system not only on fuel consumption but also on the battery pack aging. Three different scenarios, in terms of battery usage at the starting SOC values (low, medium, and maximum level) were simulated. The results of these simulations highlight the degradation and aging of the studied battery in terms of the chosen parameters of the rule-based optimized EMS.
Vulnerability Assessment of Ciphers To Fault Attacks Using Reinforcement Learning

A fault attack (FA) is one of the most potent threats to cryptographic applications. Implementing a FA-protected block cipher requires knowledge of the exploitable fault space of the underlying crypto algorithm. The discovery of exploitable faults is a challenging problem that demands human expertise and time. Current practice is to rely on certain predefined fault models. However, the applicability of such fault models varies among ciphers. Prior work discovers such exploitable fault models individually for each cipher at the expanse of a large amount of human effort. Our work completely replaces human effort by using reinforcement learning (RL) over the huge fault space of a block cipher to discover the effective fault models automatically. Validation on an AES block cipher demonstrates that our approach can automatically discover the effective fault models within a few hours, outperforming prior work, which requires days of manual analysis. The proposed approach also reveals vulnerabilities in the existing FA-protected block ciphers and initiates an end-to-end vulnerability assessment flow.
