Psychological predictors and mediators of subjective well-being in a sample of romanian teachers

The study examined psychological predictors and mediators of teacher subjective well-being. Participants included 174 teachers from urban middle and highschools. The first objective was to explore the psychological correlates of the teacher SWB: self-esteem, general self-efficacy (core self-evaluation), teacher self-efficacy, optimism (cognitive trait related to the psychological well-being), and perceived social support (psychosocial trait related to the psychological wellbeing. The second objective was to investigate the mediating role of self-efficacy in the association between optimism and subjective well-being. The third objective was to explore the mediating role of teacher self-efficacy in the relation between perceived social support and teacher subjective well-being. Correlation, linear regression and mediation model analyses through the Sobel test were computed. Results confirmed the research assumptions. The findings of this study enhance the understanding of personal factors associated with teacher subjective wellbeing. The constructs linked to subjective well-being (predictors and mediators) could be target of school psychologists’ interventions, in order to have more engaged and performing teachers in schools. The findings were discussed in the context of designing the interventions for enhancement of the subjective wellbeing among teachers.

Mediating role of empowerment between total quality management (tqm) and service recovery performance in the hotel industry

The purpose of this research was to examine the mediating effect of empowerment on the linkage between Total Quality Management (TQM) and service recovery performance in the hotel industry. Although much has been written about TQM, empowerment and service recovery performance, but the role of empowerment as a mediator in the relationship between TQM and service recovery performance has remained a relatively unexplored research area. A 93-item questionnaire is designed to measure TQM, empowerment and service recovery amongst employees in five-star hotels in Jordan, and 254 usable questionnaires were used in this study. Principal components analysis determined the factor structure and regression analysis determined the relationships between the study’s variables. The results revealed that the TQM implementations have positive effects on empowerment and service recovery performance. Moreover, the study found the full mediating effect of empowerment in the relationship between TQM and service recovery performance. Implications, limitations and future research are discussed at the end. This study proposes model of influence of TQM in service recovery performance, whereby empowerment fully mediates this relationship.

Disempowering the powerful: a critical pragmatic analysis of political discourse using brown and levinson’s face theory

Power and dominance exist everywhere and occur at the macro and micro levels. Being powerful and domineering are factors that serve as emblems for the people in the realm of politics. Power relations are overtly exercised in such discourse. But what is interesting is how power and dominance exist between or among those people who are branded as “powerful;” thus, using the Face Theory of Brown and Levinson (1978), this discourse analysis paper analyzed the power relations that transpired in a senate hearing and its relationship with the Face Threatening Acts (FTAs) used by the people involved in the discourse. A Philippine Senate hearing excerpt served as the primary corpus for analysis. Results showed that the people in the discourse were all powerful, creating tension when they projected their dominance on one another. Each member threatened and challenged their positive and negative faces. The power play evolved into a "pass-theball" effect, and no one has absolute power because it weakens once the person wielding its face is threatened. Hence, to disempower the empowered, a person must learn how to play and use FTAs such as insulting, disagreeing, disapproving, provoking, commanding, and demanding against the powerful to strike a social balance.

Impact of environment due to sars-cov-2 in india

Before the start of the SARS-CoV-2 (COVID-19) pandemic, the whole environment around us had been deemed very toxic to breathe in due to the amount of greenhouse gases that had been emitted over the centuries. The Earth faced rising temperatures, which in turn led to the melting of glaciers and rising of sea levels. Environmental degradation was happening fast due to the depletion of resources such as air, water and soil. But after the coronavirus lockdown (Talabandi) commenced, there have been changes in the environment. The lockdown still has a huge impact on people in India too. The halt of industrial production and traffic resulted in cleaner air and rivers. In India the first phase of the nationwide lockdown that began on March 24 followed by enforcement of a series of regulations had some evidences that the COVID-19 curve is flattening in the country's COVID-19 affected regions. There was a good chance Prime Minister Narendra Modi extended the lockdown (Talabandi) four times that ended on (Phase 1 (24 March-14 April)., Phase 2 (15 April-3 May)., Phase 3 (4 May-17 May) & Phase 4 (18 May-31 May). The paper focuses on different aspects of environmental impact due to SARS-CoV-2 in India.

A memetic algorithm for the inventory routing problem

In this article, we study an Inventory Routing Problem with deterministic customer demand in a two-tier supply chain. The supply chain network consists of a supplier using a single vehicle with a given capacity to deliver a single product type to multiple customers. We are interested in population-based algorithms to solve our problem. A Memetic Algorithm (MA) is developed based on the Genetic Algorithm (GA) and Variable Neighborhood Search methods. The proposed meta-heuristics are tested on small and large reference benchmarks. The results of the MA are compared to those of the classical GA and to the optimal solutions in the literature. The comparison shows the efficiency of using MA and its ability to generate high quality solutions in a reasonable computation time.

Analgesic and anti-inflammatory potential of four varieties of bell pepper (capsicum annum l.) in rodents

The aim of the study was to evaluate the analgesic and anti-inflammatory activity of four different colored (green, yellow, orange, and red) sweet bell peppers (Capsicum annuum L.) are available at the local market in Karachi, Pakistan. Their 95% ethanol extracts at 200 and 400 mg/kg were prepared and compared with commonly used analgesics (aspirin) and anti-inflammatory agents supporting its traditional use. The analgesic effects of 95% ethanol extracts of Capsicum annum L. were investigated by acetic acid-induced writhing, tail immersion and hot plate test. The anti-inflammatory activities were observed using carrageenan-induced edema of the hind paw in rats. Animals were divided into ten groups (n=7): (1) Control (2) CAG 200 (3) CAG 400 (4) CAR 200 (5) CAR 400 (6) CAO 200 (7) CAO 400 (8) CAY 200 (9) CAY 400 and (10) Standard. All the extracts were given orally. Acute toxicity was also determined by increasing the dose to 3000 mg/kg, which showed no evidence of mortality. All extracts of Capsicum significantly increased the hot plate pain threshold and remarkably reduced the carrageenan-induced rat paw oedema. Results obtained were compared with the corresponding control group, revealing that the fresh fruit extract of all four kinds of bell pepper (200 mg/kg and 400mg/kg) possess anti-inflammatory and pain-suppressing activities possibly mediated via PG synthesis inhibition

Analgesic and anti-inflammatory activities of fixed oil of macrotyloma uniflorum (lam.) verdc. in mice and rats

Macrotyloma uniflorum, commonly known as horse gram or kulthi bean, is grown as a pulse for livestock and human consumption. The beans contain about 1.3% fat, 18% protein, 15% carbohydrate, and vitamins and minerals. Traditional medicine uses it as an antihyperglycemic, antioxidant, antihypertensive and diuretic. Other important medicinal uses include the treatment of renal stones, obesity, piles, oedema and fever. The present study evaluated analgesic (by acetic acid-induced writhing, hot plate and tail flick tests in mice) and anti-inflammatory (carrageenan-induced paw oedema in rats) activities of Macrotyloma uniflorum fixed oil (MUFO). Four groups were included in the study: Group I: Normal Saline Control (2ml/kg), Group II: MUFO (2ml/kg), Group III: MUFO (4ml/kg), and Group IV: Standard Acetyl salicylic acid (ASA 300mg/kg). All results were significant; however, the tail flick and paw oedema tests observed a delayed onset of action. The oil's acute oral toxicity was also checked in mice and was found safe up to a 4ml/kg dose, as no signs of toxicity and mortality were observed. It is concluded that Macrotyloma uniflorum fixed oil may possess analgesic and anti-inflammatory activity, which can be related to a peripheral mechanism of action.

Ethnopharmacognosy, phytochemistry and pharmacology of genus caesalpinia: a review

The genus Caesalpinia belongs to the family Caesalpiniaceae and includes 280 species distributed in tropic and subtropical regions of the world. Historically, species of the genus Caesalpinia have been used to treat a wide range of ailments, such as malaria, ascariasis, dysentery, fever, rheumatism, and influenza. Phytochemical works led to the isolation of triterpenoids, diterpenes, flavonoids, steroids and phenolic compounds. Pharmacological studies have shown that the extracts and compounds isolated from this genus exhibited anticancer, anti-inflammatory, anti-malarial, antipyretic, anti-microbial, anti-rheumatic, antiulcer and anti-diabetic activities. Therefore, this review aims to provide a comprehensive overview of the genus Caesalpinia's ethnopharmacology, phytochemistry and pharmacology.

An ontology-based approach to reduce the negative impact of code smells in software development projects

The quality of software systems may be seriously impacted by specific types of source code anomalies. For example, poor programming practices result in Code Smells (CSs), which are a specific type of source code anomalies. They lead to architectural problems that consequently impact some significant software quality attributes, such as maintainability, portability, and reuse. To reduce the risk of introducing CSs and alleviate their consequences, the knowledge and skills of developers and architects is essential. On the other hand, ontologies, which are an artificial intelligence technique, have been used as a solution to deal with different software engineering challenges. Hence, the aim of this paper is to describe an ontological approach to representing and analyzing code smells. Since ontologies are a formal language based on description logics, this approach may contribute to formally analyzing the information about code smells, for example, to detect inconsistencies or infer new knowledge with the support of a reasoner. In addition, this proposal may support the training of software developers by providing the most relevant information on code smells. This ontology can also be a means of representing the knowledge on CSs from different sources (documents in natural language, relational databases, HTML documents, etc.). Therefore, it could be a valuable knowledge base to support the struggle of software developers and architects either to avoid CSs or to detect and remove them. The ontology was developed following a sound methodology. The well-known tool Protégé was used to manage the ontology and it was validated by using different techniques. An experiment was conducted to demonstrate the applicability of the ontology and evaluate its impact on speeding up the analysis of CSs.

Attention is all you need

The dominant sequence transduction models are based on complex recurrent or convolutional neural networks that include an encoder and a decoder. The best-performing models also connect the encoder and decoder through an attention mechanism. We propose a new simple network architecture, the Transformer, based solely on attention mechanisms, dispensing with recurrence and convolutions entirely. Experiments on two machine translation tasks show these models to be superior in quality while being more parallelizable and requiring significantly less time to train. Our model achieves 28.4 BLEU on the WMT 2014 Englishto-German translation task, improving over the existing best results, including ensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task, our model establishes a new single-model state-of-the-art BLEU score of 41.0 after training for 3.5 days on eight GPUs, a small fraction of the training costs of the best models from the literature.

Using interactive web-based animations to help students to find the optimal algorithms of river crossing puzzles

To acquire algorithmic thinking is a long process that has a few steps. The most basic level of algorithmic thinking is when students recognize the algorithms and various problems that can be solved with algorithms. At the second level, students can execute the given algorithms. At the third level of algorithmic thinking, students can analyze the algorithms, they recognize which steps are executed in sequences, conditions or loops. At the fourth level, students can create their algorithms. The last three levels of algorithmic thinking are: the implementation of the algorithms in a programming language, modifying and improving the algorithms, and creating complex algorithms. In preliminary research related to algorithmic thinking, we investigated how first-year undergraduate computer science students of J. Selye University can solve problems associated with the second, third and fourth level of algorithmic thinking. We chose these levels because these levels do not require to know any programming language. The tasks that students had to solve were for example: what will be the route of a robot when it executes the given instructions, how many times we need to cross a river to carry everyone to another river-bank. To solve these types of tasks requires only good algorithmic thinking. The results showed that students reached 81.4% average score on tasks related to the execution of given algorithms, 72.3% average score on tasks where they needed to analyze algorithms, and 66.2% average score on tasks where students needed to create algorithms. The latter type of tasks were mostly various river-crossing problems. Even though, that students reached a 66.2% average score on these tasks, if we had accepted only solutions with the optimal algorithms (minimal number of river crossing), they would have reached only a 21.3% average score, which is very low. To help students find the optimal algorithms of river crossing puzzles, we developed several interactive web-based animations. In the last part of this paper, we describe these animations, we summarize how they were created and how they can be used in education. Finally, we conclude and briefly mention our plans related to our future research.
