The Dark Tetrad of personality and the tendency to engage in revenge porn

Revenge porn is an increasing and pervasive phenomenon. Despite this, the knowledge and understanding of this behaviour is limited, especially the psychological characteristics of perpetrators of revenge porn. The Dark Tetrad of personality: Machiavellianism, psychopathy, narcissism, and sadism, has been associated with a range of antisocial behaviours. Recent research indicates a relationship between the Dark Tetrad and revenge porn proclivity. The present study extended these findings by investigating the relationship between revenge porn proclivity and the Dark Tetrad using more trait-specific measures. A community sample of 306 participants, aged 18-77, were recruited online. Participants completed a series of personality measures assessing the Dark Tetrad and the Revenge Porn Proclivity Scale. Results show a significant positive correlation between the Dark Tetrad and the propensity to engage in revenge porn, as hypothesised. Additionally, multiple regression analysis shows the overall model significantly predicts revenge porn proclivity, however, sadism was the only independent predictor of proclivity. These findings add to the understanding of the psychological characteristics of perpetrators. The practical implications are discussed in relation to addressing the approval of this behaviour and informing prevention, intervention, and education strategies. The limitations of this study and recommendations for future research are also discussed.
Hurdles to inference: The demographic correlates of survey breakoff and shirking

Objective : Various shirking behaviors in survey-taking can inhibit researchers’ ability to draw unbiased inferences from the resulting data. We deﬁne three types of shirking behavior, identify their demographic correlates among survey respondents, show how shirking may lead to biased or incorrect inferences, and oﬀer suggestions for navigating these threats. Method : We analyze responses from a large (N=3,256), representative survey of Americans, identify indicators of three types of shirking, and regress these indicators on survey ﬁrm administrative data on respondent characteristics to discover the respondent characteristics associated with diﬀerent shirking types. Results : The data suggest women are more likely to break oﬀ during a survey, while men are more likely to shirk while completing the instrument. In addition, young, less educated respondents are more likely to use straight-lining or other satisﬁcing tactics. Conclusion : Systematic diﬀerences in shirking behaviors across these demographic groups make us likely to misunderstand the (reported) social behavior of women and men, young and old, or more and less educated, in diﬀerent ways . This is particularly problematic for testing behavioral theories that generate gender, age, or education-speciﬁc predictions, or, predictions regarding attitudes or behaviors that strongly correlated to these characteristics.
The Effects of Magnetic Water on Growth Performance and Blood Parameters of Nile Tilapia (Oreochromis niloticus) under Different Stocking Densities

The present study was designed to investigate the effects of magnetic water and different stocking densities on water quality parameters, growth performance, feed utilization, chemical composition and Blood biochemical of Nile tilapia ( Oreochromis niloticus ). A total of 180 healthy monosex Nile tilapia fingerlings with an average initial body weight of 33.24 ± 0.47 g were randomly distributed into 18 glass aquaria. The experiment was based on a 2 × 3 factorial design with three stocking densities; (5, 100, and 150 fingerlings/m 3 ), and two types of water, normal water (NW) and magnetic water (MW). Experimental fish were fed on the commercial diet (30.11% protein) based on a feeding rate of 3% from body weight for all groups. Water quality parameters, growth performance parameters, feed utilization, chemical composition and blood parameters were calculated in all groups at the end of the experiment after eight weeks. The results indicated that water quality, growth performance, feed utilization, and chemical composition improved significantly in magnetic water groups compared to normal water groups at the three stocking densities. As for blood parameters, there were no significant differences in all groups. In conclusion, applying magnetic water on aquaculture of Nile tilapia farming improves water quality parameters, fish growth performance, feed utilization, and chemical composition at different stocking densities.
Isolation and partial purification of invertase from different baker's and distillery Saccharomyces cerevisiae

Invertase enzyme from different commercial kinds of Baker’s and distillery Saccharomyces cerevisiae was isolated and partially purified as a crude enzyme by salt stress process and ethanol precipitation. The lyophilization takes place for the enzyme isolated from activated distillery S. cerevisiae. The activities of partially purified invertase isolated from the different five baker yeasts under study ranged between 975 and 1801 IU/ml/min. While the activities of enzymes isolated from distillery yeasts before and after activation were 120 and 1100 IU/ml/min. The activity of lyophilized partially purified powder of enzyme isolated from activated distillery yeast was19300 U/g. The Km and Vmax values of the enzyme isolated from activated distillery yeast were 7.56 mg/ml and 294.12 IU/ml/min, respectively. These results were compared to those values of invertase isolated from Egyptian active dry Baker’s yeast and the commercial invertase data sheet with a sample of sweetase 20 p enzyme obtained from Germany stern enzyme company. The results recorded in this paper clearly appeared that the active powder invertase could be obtained from activated distillery yeast by the easy and inexpensive method.
Evaluation and comparison between online and traditional learning of veterinary anatomy

In the shadow of covid-19 pandemic, electronic learning (E-learning), also known as online classes, has become the main option. Therefore, the aim of this study was to assess the efficacy of online learning in veterinary anatomy, as well as the theoretical and practical outcomes that resulted from it. it compares the exam scores of students in both teaching methods (conventional and E-learning). About 100 students were used in this study. Furthermore, it demonstrated the students' practical knowledge in the area of E-online learning. The first semester was dedicated to formal education. The second semester was completed entirely online. The findings revealed that during lectures, complex involvement in online activities is substantially reduced. The awareness of students was assessed by comparing student grades from these three semesters. In comparison to traditional schooling, the exam results showed an irregular distribution in E-learning and online tests, with E-learning scores substantially higher. During the E-learning time, the functional laboratory was completely absent. The practical part, of the veterinary anatomy classes, involves laboratory participation to show students various systems of the animals and enable them to use different techniques, training them for future classes such as clinical and surgical classes. The results revealed that reached the conclusion that e-learning is inadequate for teaching veterinary anatomy.
Influence of Some Organic Acids on Availability and Adsorption of Phosphorus as well as Corn Growth in A Clay Soil

Hypotheses that have been tested for this study are the effects of some organic acids on availability and adsorption of phosphorus (P) in clay soil as well as corn growth and phosphorus uptake. In a pot experiment the used organic acids [citric, tartaric and their mixture at ratio of 1:1 (w/w)], were added to soil at levels of 0, 0.2, 0.5 and 1% (w/w). This experiment was arranged in a randomized complete design with three replicates and planted by corn. The results obtained in this study reveal that organic acids addition significantly reduced P availability (Olsen-P) from 11.9 mg kg‒1 for control to 8.0 mg kg‒1 at 0.5 % level of citric and mixture of citric and tartaric acids. The maximal adsorption capacity of phosphorus (b) significantly increased with additions of organic acids. Applying mixture of citric and tartaric acids increased significantly sorption intensity constant (n). A significant increase of the sorption capacity constant (Kf) happened with mixed citric and tartaric acids at all concentrations. But, adding 1% citric acid and 1% tartaric acid to clay soil caused significant decreases in Kf parameter of phosphorus. The fresh weight of corn and P uptake were enhanced significantly with the addition of organic acids.
The Impact of Talent Management Practices on Employees Engagement in Sharm El-Sheikh Hotels

(JAAUTH) Vol. 22, No. 2 (June 2022), PP.132-153. Talent management is one of the most important activities of human resource management, as it makes the recruitment process more efficient and effective by reaching a high level of work engagement by exploring the potential energies of employees and filling vacant positions with highly qualified talented staff, which is reflected in guest satisfaction. The main argument of this paper is to analyze the relationship between talent management practices and employees engagement at five star hotels in Sharm El-Sheikh city, which is considered as a major tourism destination in Egypt. The field study was conducted using questionnaires distributed to 384 employees in the human resource departments, 299 were valid. SPSS software -version 22-, was used to analyze the data. The findings of this paper showed that there are significant and positive relationships between talent management and employee engagement, where talent management practices are reflected on guest satisfaction, which is achieved if the hotel has talented and highly qualified employees, as their skill is reflected in the product and service provided.
A Cross-National Multilevel Analysis of Fear of Crime: Exploring the Roles of Institutional Confidence and Institutional Performance

Drawing upon Wave 7 of the World Value Survey, this study performed multilevel analysis on fear of crime among 47,996 residents from 36 diverse nations. Confidence in the government and perceived government performance were identified as significant predictors of crime fear. Further analysis showed the effect of confidence in the government stemmed primarily from between-country variation, whereas both within-country and between-country variation in perceived government performance shaped fear of crime. In addition, macroeconomic factors and the proportion of urban population, but not national-level homicide rate, were found to be salient country-level predictors. The findings contextualize the elevated fear of crime in some countries despite declining crime rates and inform the recommendation that institutional confidence and performance be prioritized in crime fear reduction efforts.
Student Perspectives on Implementation and Impact of Positive Behavioral Interventions and Supports (PBIS) in Their Middle Schools

Positive Behavioral Interventions and Supports (PBIS) is an evidence-based framework for promoting positive school climates and improving student social and behavioral outcomes. Yet secondary schools have lagged behind elementary schools in their adoption and implementation of PBIS. The transition from elementary to middle school is marked by a host of developmental and environmental changes that creates a critical window for establishing supportive school environments. We conducted a series of focus groups with middle school students (N = 45) attending PBIS schools to learn about their views and understandings of PBIS, the perceived impact of these programs, the extent to which they were involved in PBIS, and their recommendations for improving their school’s program. Although middle school students’ understanding of PBIS was often focused on their acknowledgment system, students identified a range of impacts beyond improving student behavior. Students also expressed a desire for more (a) transparent communication between staff and students and (b) opportunities for students to be actively involved in their school’s program. We discuss the implications of these findings with respect to increasing the uptake and impact of PBIS in secondary schools.
ISOLATION AND CHARACTERIZATION OF BACTERIAL VIRUSES SPECIFIC TO BACILLUS MEGATERIUM

This study was conducted to isolate and characterize bacteriophages specific to Bacillus megaterium. Seven single lytic phage isolates specific to B. megaterium were successfully isolated from rhizosphere soil of maize plants, growing in the Experimental Farm of Faculty of Agriculture, Minia University, Minia, Egypt. The phages were characterized on the basis of the optimum pH for viral infection, thermal inactivation point, sensitivity to UV radiation, host specificity, as well as particle size, and morphology. The isolated phages exhibited tolerance to alkaline and acidic reactions. All phage isolates were found to be of head and tail types. On the basis of the differences in the studied characteristics of these phages, the seven phage isolates were divided into four groups (A, B, C and D). Phages of each group exhibited the same features (i.e. the optimum pH for infection, thermal inactivation point, sensitivity to UV radiation, host specificity, as well as phage particle size and morphology). Accordingly, the seven phage isolates are belonging to four phage types. These four phage types were designated Bm1, Bm2, Bm3 and Bm4.
Lead Removal from Contaminated Water Using Seaweed-Iron Oxide Nanoparticles Composite

Water sacristy is one of the most global concerns in the last decades, which can be solved by reusing wastewater. Lead, as a potentially toxic element, is one of the most dangerous potentially toxic elements that have to be eliminated from contaminated water resources. Bio-sorbents, like macroalgae (seaweeds) have been recently investigated for removing toxic elements from water. It is hypothesized that mixing seaweeds with nanoparticles (e.g. iron oxide) might improve removal efficiency of Pb ions. In this study seaweeds, iron oxide nanoparticles and their composite were used for lead removal from contaminated water with up to 50.0 mg L. The results showed that all sorbents under investigation were successful for Pb sorption, and the engineered composite was superior with removal efficiency of 91%. In addition, the engineered composite showed an ease of separation following sorption process using a magnet. Freundlich isotherm model was the best for describing the adsorption of Pb onto the sorbents material under this investigation. This study is a step on the way to improve the separation of bio sorbents from aqueous solutions after the removal of contaminants.

Can Sensory Marketing Factors Improve the Customers' Pleasure and Arousal in Egyptian Resort Hotels?

(JAAUTH) Vol. 22, No. 2, (June 2022), PP.111-131. Sensory marketing is a type of marketing orientation that targets customers’ senses, through customer’s emotionally influencing to form mental connections. This study aims to determine the relationship between sensory marketing factors (sight, smell, sound, taste, and touch) and customers' pleasure and arousal in Egyptian hotels and resort. A quantitative research survey was used. The sample size was 493 customers of 25 five-star resort hotels in Egypt. The findings revealed that, sensory marketing factors have a positive and significant effect on the customers' pleasure and arousal in Egyptian resort hotels, howerver, touch, as a component of sensory marketing factors, was not significant on the customer’s arousal.The study contributes theoretically by validating the theory of emotional accidents as an effective underpinning theory in explaining customers’ pleasure and arousal; The study recommends that marketing managers in resort hotels should pay more attention on the emotional aspect through influencing on customer's senses for satisfying their desires and making them repeating customers.
E-cadherin Expression in Canine Gastric Carcinomas: Association with Clinicopathological Parameters

E-cadherin (E-cad) is a cell-adhesion molecule known for its tumor-invasion suppressor function. E-cad expression was examined immunohistochemically in a series of canine tissue samples, including normal gastric mucosa (NGM; n = 3), gastric carcinomas (GC; n = 33), adjacent non-neoplastic mucosa (NNM; n = 32), neoplastic emboli (n = 16) and metastatic lesions (n = 9). The relationship between E-cad expression and clinicopathological features were investigated. In NGM, epithelial cells showed strong latero-lateral membranous expression of E-cad, and this pattern was considered normal. The membranous staining was preserved in all specimens of NNM (100%), whereas abnormal E-cad expression was found in 87.9% of the GCs. A marked difference in E-cad expression was observed between normal and malignant tissues (p < 0.0002). Abnormal E-cad expression was significantly more frequent in poorly/undifferentiated carcinomas (96%) and diffuse (95%) and indeterminate carcinomas (100%) than in well-differentiated/intestinal ones (62.5%; p = 0.0115 and p = 0.0392, respectively). There was significant association between abnormal E-cad expression and the depth of invasion (p = 0.0117), and the presence neoplastic emboli (p = 0.0194). No statistically significant differences in E-cad expression were observed concerning tumor location, histological type according to WHO classification, and presence of metastatic lesions. Therefore, deregulation of E-cad expression may play a role in canine gastric carcinogenesis and in tumor progression; moreover, it might be a prognostic tool for canine gastric cancer.
Procrastination Behavior and Self-efficacy Among Students: A Mixed Method Study

The present research examined procrastination behavior and self-efficacy among postgraduate students by using mixed method research in two studies. Objective of this research was to measure procrastination, self-efficacy and further to explore the factors behind these behaviours through quantitative and qualitative research, respectively. For study-I, in quantitative research, sample of 282 students was selected by using stratified random sampling technique. To measure procrastination “Procrastination Scale” for student population (Lay, 1986) and for Self-efficacy “General Self-efficacy Scale” (Schwarzer & Jerusalem, 1995) were used. Descriptive statistics, correlation analysis and Chi-square were used to analyse the data. Results indicated that there is a significant negative correlation between procrastination behavior and self-efficacy. The level of procrastination was found at non-clinical level 5(1.5%), sub-clinical level 165(68.5%), clinical level 110(39.0) and 2(0.7%) reported the need to seek clinical attention. Findings of chi-square illustrate no association of procrastination with demographic of age, faculty and GPA. In study-II, through qualitative approach, a focus group discussion was conducted with eight participants. Data were recorded by a tape recorder which was transcribed and analysed by using thematic analysis. Results revealed four themes from qualitative discussion; 1) description of procrastination behavior, 2) casual and precipitating factors, 3) impact on life and 4) strategies to overcome/reduce procrastination behavior. Through the findings of both studies, it can be concluded that procrastination behaviour is prevalent among students and there is a need to implement strategies to reduce this behaviour.
The Validation of the Voice-Related Quality of Life (V-RQOL): Arabic version

ABSTRACT Objective: This study aimed to translate the original Voice-Related Quality of Life (V-RQOL) version into Arabic language version and to evaluate the validity and reliability of the translated Arabic version of the V-RQOL in order to be used as a valuable test to assess any voice problems influencing the everyday routine duties of the Arabic speaking patients with voice disorders. Patients and Methods: The V-RQOL questionnaire is made up of 10 items. The questionnaire was translated from English to Arabic by two doctors both were native Arabic speakers and fluent in English as well. Then the translated copy was revised by another two native Arabic speaking physicians and fluent in English as well. The questionnaire was applied on 50 controls healthy participants and 100 patients with voice disorders who were recruited from the Phoniatric outpatient clinic of Benha University Hospital, between the period from May 2020 till June 2021.The V-RQOL questionnaire translated version was completed twice by 30 participants with 2 weeks apart to analyze the test-retest reliability. The person completed the questionnaire by him/herself or if he/she is illiterate, it was done by the help of the physician. Additional to the V-RQOL questionnaire, the participants underwent full history taking and Full laryngeal assessment and completed the Voice Handicap Index (Arabic version) as well. Results: The V-RQOL questionnaire is as valid & reliable tool as the VHI for patients with voice disorders. It was shown in the Cronbach's alpha coefficient for all 10 questions of V-RQOL and the thirty questions of VHI were 0.879 & 0.94 respectively, which indicates a very good level of reliability of both questionnaires. Conclusion: The V-RQOL questionnaire clearly measures the socio-emotional aspects and the physical-functional aspects of voice disorder patients in a simple, rapid, easy way to apply and not time-consuming tool which is suitable for the countries with high population density like Egypt.
