Nomophobia scale, daily smart phone use periods and demographics data is collected using a questionnaire which is conducted to undergraduate students who are smart phone and mobile internet users (N=312) in Malatya. We found that 55% of the students are nomophobia and average smart daily smart phone use period is 6.43 hours, there is a positive and significant association between nomophobia scores and daily smart phone use periods and negative and significant association between nomophobia scores and academic success. We employed structural equation modelling to explore the relationship between nomophobia (with four dimensions) and academic success and saw that nomophobia significantly decrease academic success in this sample of undergraduate students. Our findings show that nomophobia is an enormous problem for the academic accomplishments of undergraduate students, which should be dealt by education managers, parents and students themselves.

Expanding the Range: AuCu Metal Aerogels from H2O and EtOH

Due to their self-supporting and nanoparticulate structure, metal aerogels have emerged as excellent electrocatalysts, especially in the light of the shift to renewable energy cycles. While a large number of synthesis parameters have already been studied in depth, only superficial attention has been paid to the solvent. In order to investigate the influence of this parameter with respect to the gelation time, crystallinity, morphology, or porosity of metal gels, AuxCuy aerogels were prepared in water and ethanol. It was shown that although gelation in water leads to highly porous gels (60 m2g−1), a CuO phase forms during this process. The undesired oxide could be selectively removed using a post-washing step with formic acid. In contrast, the solvent change to EtOH led to a halving of the gelation time and the suppression of Cu oxidation. Thus, pure Cu aerogels were synthesized in addition to various bimetallic Au3X (X = Ni, Fe, Co) gels. The faster gelation, caused by the lower permittivity of EtOH, led to the formation of thicker gel strands, which resulted in a lower porosity of the AuxCuy aerogels. The advantage given by the solvent choice simplifies the preparation of metal aerogels and provides deeper knowledge about their gelation.
An Empirical analysis of freight train derailment rates for unit trains and manifest trains

Rail is a safe and efficient mode of transporting hazardous materials (hazmat). In the past decade, the hazmat traffic transported by unit trains has significantly increased in the United States. As a result, a comprehensive understanding of the safety and risk of hazmat unit trains is important and can contribute to the identification, evaluation, and implementation of risk mitigation strategies. Limited prior research has focused on unit train derailment risk analysis. This paper develops a quantitative analysis of freight unit train derailment characteristics and compares those statistics to non-unit, manifest trains (mixed trains). Mainline freight train derailment data on Class I railroads between 1996 and 2018 were analyzed for hazmat unit trains, non-hazmat unit trains, and manifest trains. Derailment rates, measured by three traffic exposure metrics (train-miles, ton-miles, and car-miles) were estimated and compared. The analyses showed that a unit train has a 30% lower derailment rate in terms of ton-miles and car-miles than manifest trains, while the derailment rate per million train-miles of unit trains is slightly greater than that of manifest trains. Loaded unit trains have roughly four-fold higher derailment rate in terms of train-miles and car-miles than that of empty unit trains. Within loaded unit trains, hazmat unit trains have lower derailment rates than non-hazmat unit trains. Overall, heavier and shorter loaded unit trains tend to have greater derailment rates in terms of all three traffic exposure metrics. A causal analysis was also conducted for the three types of train. Infrastructure causes were the most frequent in all train types and length followed by equipment-related causes. These statistics provided important information for rational allocation of risk mitigation resources to improve rail hazmat transportation safety.
A study on impact of online service quality on customer satisfaction in e-retailing business

This paper checks the effect of service quality in the online retail business on customer satisfaction along with the association of the demographic variables through the opinion from the respondents particularly 524 college students in India selected through purposive sampling method. The goodness of model fit was found using Structural equation Modelling (SEM) of AMOS and the relationship between e-service quality and customer satisfaction was analyzed through Inter - correlation and Regression analysis. The results show that e-service quality factors have a positive impact and also highlighted as a significant predictor for customer satisfaction. The study also revealed that service recovery is acting as a mediating factor between service failure and customer satisfaction. The output of this study will support the online retailers to formulate their strategies in view to provide very good and excellent services to their customers.
Examining employee retention and motivation: the moderating effect of employee generation

PurposeThis study explored moderating effects of employee generations on factors related to employee retention and motivation in the workplace.Design/methodology/approachThe authors developed a survey instrument and collected the survey data via Amazon Mechanical Turk. After filtering out bad responses, the authors ended up with 489 sample cases for this study. The authors used structural equation modeling for data analysis.FindingsEvidence showed that only transformational leadership was significantly related to retention of Generation X employees and only work–life balance had a significant relationship with intrinsic motivation. For Generation Y employees, transformational leadership was the only factor affecting their retention while both transformational leadership and autonomy showed significant impacts on their intrinsic motivation. Generation Z employees reported that only transformation leadership affected their retention while transformational leadership, corporate social responsibility and autonomy were significantly related to their intrinsic motivation in the workplace. All three generations showed statistical significance between intrinsic motivation and employee retention.Practical implicationsThis study could help business practitioners increase employees' work motivation and retention.Originality/valueFirst, our results revealed interesting similarities and differences between generations in terms of the factors that affected employees' retention and motivation. Second, this study proved that employees' generation affects the impacts of transformational leadership, CSR, autonomy, WLB and technology on their motivation and retention in the workplace. Third, the results of our study also showed that employees of different generations are intrinsically motivated by different factors, proving the importance of considering generational differences in motivation literature.
Persistent Eastward EEJ Enhancement During the Geomagnetic Storm Recovery Phases

Recent case studies disclosed that sometimes the dayside ionospheric equatorial electric field underwent persistent long‐duration (>4 hr) eastward enhancements during geomagnetic storm recovery phases, rather than anticipated decrease or reversal. However, it is still unknown the occurrence and morphology of the persistent enhancement as well as its impact on the low‐latitude ionospheric plasma distribution. For the first time, we examined the issue with superposed epoch analyses of equatorial electrojet (EEJ) and GNSS total electron content (TEC) responses in the American (49°W) and Indian (78°E) sectors. The occurrence rates of the persistent enhancement during storm recovery phases are more than 30%, with higher occurrence rates in second to fourth days of the recovery phase, equinoxes, and American sector. The corresponding averaged EEJ and TEC responses were disclosed and compared with those storm samples without the persistent enhancement. On the first day of recovery phase, the dayside equatorial ionosphere was dominated by the prevalent westward electric field and causative inhibited equatorial fountain. In contrast, after the first day, the dayside morphologies showed different patterns: (a) for the persistent cases, the large eastward EEJ and TEC enhancement indicated the enhanced eastward electric field at forenoon and causative intensified equatorial fountain. (b) For the storms without the persistent cases, the general westward EEJ and equatorial TEC enhancements were dominated. Our study indicates that dayside eastward enhancement is an important disturbed pattern of equatorial ionospheric electric field during the late recovery phases, and the enhancement generally causes the intensification of equatorial ionization anomaly.
Seeking Causality in the Links between Time Perspectives and Gratitude, Savoring the Moment and Prioritizing Positivity: Initial Empirical Test of Three Conceptual Models

We provide an initial empirical test of three conceptual models reflecting possible patterns of causality effects in the relationships between time perspective (TP), gratitude, savoring the moment, and prioritizing positivity (referred to as well-being boosters, WBBs), and mental well-being. The first one, trait-behavior model, states trait TPs increase the tendency to use specific WBBs in order to increase mental well-being. The second model, the accumulation model, proposes that a regular practice of particular WBBs fosters adaptive TPs which in turn impact well-being. The third model, the feedback loop, suggests that WBBs and positive TPs reciprocally strengthen one another and together contribute to higher mental well-being. Participants (N = 206; Mage = 30.90, SD = 8.39, 74% females) filled questionnaires measuring TPs, WBBs, and well-being twice, in a one-year interval. Using cross-lagged panel analyses we examined the direction of causation in the relationships among the variables. Past-Positive had a significant cross-lagged effect on gratitude, Present-Fatalistic had a significant effect on savoring. Both Past-Negative and Present-Fatalistic perspectives displayed significant causal effects on well-being. The results partly support the trait-behavior model. However, given that the second wave was conducted shortly after the onset of the COVID-19 pandemic, further studies are required to better understand the interplay between the studied traits.
Evaluation of Computed Tomography Scoring Systems in the Prediction of Short-Term Mortality in Traumatic Brain Injury Patients from a Low- to Middle-Income Country

The present study aims to evaluate the accuracy of the prognostic discrimination and prediction of the short-term mortality of the Marshall computed tomography (CT) classification and Rotterdam and Helsinki CT scores in a cohort of TBI patients from a low- to middle-income country. This is a post hoc analysis of a previously conducted prospective cohort study conducted in a university-associated, tertiary-level hospital that serves a population of >12 million in Brazil. Marshall CT class, Rotterdam and Helsinki scores, and their components were evaluated in the prediction of 14-day and in-hospital mortality using Nagelkerk's pseudo-R2 and area under the receiver operating characteristic curve. Multi-variate regression was performed using known outcome predictors (age, Glasgow Coma Scale, pupil response, hypoxia, hypotension, and hemoglobin values) to evaluate the increase in variance explained when adding each of the CT classification systems. Four hundred forty-seven patients were included. Mean age of the patient cohort was 40 (standard deviation, 17.83) years, and 85.5% were male. Marshall CT class was the least accurate model, showing pseudo-R2 values equal to 0.122 for 14-day mortality and 0.057 for in-hospital mortality, whereas Rotterdam CT scores were 0.245 and 0.194 and Helsinki CT scores were 0.264 and 0.229. The AUC confirms the best prediction of the Rotterdam and Helsinki CT scores regarding the Marshall CT class, which presented greater discriminative ability. When associated with known outcome predictors, Marshall CT class and Rotterdam and Helsinki CT scores showed an increase in the explained variance of 2%, 13.4%, and 21.6%, respectively. In this study, Rotterdam and Helsinki scores were more accurate models in predicting short-term mortality. The study denotes a contribution to the process of external validation of the scores and may collaborate with the best risk stratification for patients with this important pathology.
Psychometric Properties of the Academic Procrastination Scale (APS) in Brazil

Academic procrastination has a significant influence on students’ lives, being related to several relevant variables, such as lower self-esteem, higher levels of academic anxiety, and fear of failure. The development and adaptation of reliable instruments help to assure a more in-depth study of academic procrastination. The present research aimed to adapt and assess evidence of validity and reliability of the scores of the Academic Procrastination Scale (APS) for a Brazilian sample (N = 1241). In Study 1, an exploratory factor analysis supported the unidimensional structure of the APS (25 items). In Study 2, the one-factor structure had an adequate model fit via confirmatory factor analysis. Also, through item response theory, the APS items showed adequate discrimination, difficulty, and level of information. The scores of the APS were also significantly correlated with the scores of the Tuckman Procrastination Scale, providing evidence of convergent validity.
Gender-Based Differences in the Consumption of Food Rich in Fibre and Its Relationship with Perceived Mood Status: A Cross-Sectional Study

It is unclear whether gender-based differences in dietary fibre intake exist in the relationship between daily fibre consumption and the prevalence of mood disorders. This study aims to examine the effects of dietary fibre consumption on mood status between genders in Saudi Arabia. A total of 359 Saudi participants completed the survey. The data showed that women consumed 14 g fibre/day and had a mild depression score, while men consumed 12 g/day and had very severe stress. The consumption of low-to-moderate servings of fruit or very low servings of nuts and seeds was associated with stress in men. Moderate levels of depression among women were likely to occur with low-to-moderate servings of nuts and seeds. Moderate-to-high stress levels among women appeared to be associated with low-to-moderate servings of vegetables, while depressed men consumed vegetables in low-to-moderate servings. However, anxious women who experienced mild levels consumed low-to-moderate servings of vegetables, and those with a mild-to-moderate level of anxiety consumed low-to-moderate servings of bread, whole grains, and cereals. The preliminary results showed that the consumption of 12 g fibre/day is not enough to relieve stress among men, while 14 g/day reduces the level of depression to mild among women. Fibre-rich foods, e.g., vegetables, nuts and seeds, fruit, bread, cereals and legumes, lower the degree of negative moods, but this is not only attributed to fibre, as there are other influential nutrients.
Bithiophene derivative induced apoptosis and suppression of Akt pathway in mouse leukemic model.

BACKGROUND Bithiophene derivatives show a promising anti-cancer potential. We previously showed that Bithienyl Fluorobenzamidine (BFB) has an anti-proliferative effect against several leukemia cell lines. Acute myeloid leukemia (AML) accounts for 18% of the total leukemia cases worldwide with heavier burden during the past 30 years. Therefore, the main aim remains the discovery of safe and effective medications. OBJECTIVE The current research aims to investigate the anti-cancer efficacy of BFB and its effect on the apoptosis in the 7,12-Dimethylbenz[a]anthracene (DMBA) induced AML in mice. METHODS AML was induced in mice by DMBA and then treated by 2 different doses of BFB. After BFB treatment, the hematological and histological pattern changes was examined. Furthermore, the molecular effect of BFB on apoptosis, cell cycle markers and Protein kinase B (Akt) pathway was examined using qPCR, Western blotting and ELISA. RESULTS BFB treatment ameliorates leukemia histological and hematological markers significantly, despite non-significant changes in normal mice. This improvement exhibits cell cycle arrest and apoptosis induction, represented by elevation of tp53/p53, p21/p21, Caspase3 and downregulation of ckk1/Cdk1 in the bone marrow, as well as Akt pathway suppression. CONCLUSIONS Our results establishes BFB as a promising therapeutic candidate against AML through cell cycle arrest, apoptosis induction and Akt pathway modulation.
Are School Leaders in Tanzania Effective in Fostering Instructional Change? Unveiling This Black Box from the Feedback Perspective

Feedback is among the most powerful influences on learning a new skill. Surprisingly, very little attention has been given to studying this issue in relation to interactions between school leaders and frontline teachers particularly during the adoption of educational changes. This qualitative study provides findings on feedback provided to teachers by school leaders in relation to the adoption of a new Tanzanian curriculum. The data were collected from teachers and leaders in three schools using document reviews and individual interviews, and were processed through thematic analysis. Findings revealed various technical issues with regard to feedback method, timing, and quality. Factors that influenced these and their likely influences on the professional growth of the teachers are discussed within the context of reviewed literature. Recommendations for policy and practice are provided.
Translating humorous literature from Vietnamese into Italian language: an empirical study of humour reception

The empirical study presented in this article aims to determine some of the linguistic and cultural elements that can influence the production process and the reception of humour and to verify the applicability of the General Theory of Verbal Humor (GTVH) to humorous literary translation. 60 Vietnamese and 60 Italian participants had to read and rate the level of humorousness of excerpts taken from the Vietnamese novel Số Đỏ (Vũ Trọng Phụng, 1936) and its correspondent Italian translation (Il gioco indiscreto di Xuan, 2012). By comparing their feedback, it was possible to observe that one is more likely to appreciate humour when one is not part of the categories subject to ridicule/irony/satire; and that a direct contact with the original language and culture constitutes an important role in humour understanding and appreciating. Also, a comparison between the rating that the Italian participants assigned to the official Italian translation and an alternative version allowed us to analyze the role of Language Knowledge Resource (GTVH). According to the Italian participants, although the two versions of the translation, which share the first five levels of Knowledge Resources, were remarkably similar (as predicted by the GTVH), they were dissimilar in terms of humour and in readers' preferences. I therefore argue that, although the GTVH is a useful tool for analyzing and verifying the similarity between the source and target text, it has proved to be impractical and not always reliable if we want to use it as a parameter of the translation of literary humorous texts.
The Need to Control Thoughts in Eating Disorder Outpatients: A Longitudinal Study on Its Modification and Association with Eating Disorder Symptom Improvement

The metacognition of needing to control thoughts has been implicated in eating disorders (EDs)—specifically, in association with the drive for thinness and over-control. To date, it has yet to be investigated longitudinally in ED outpatients undergoing CBT-based treatment. The current study aims to examine whether endorsing a need to control thoughts undergoes modifications during CBT-based treatment for EDs and whether its modification correlates with treatment response in terms of reduced ED symptomatology. Seventy female ED outpatients (34 with AN, 29 with BN, 7 with OSFED) were assessed at baseline and at the end of treatment with the Metacognitions Questionnaire (MCQ), the Eating Attitudes Test (EAT-40), and the General Health Questionnaire (GHQ). Post-treatment, significant reductions were observed in MCQ-need to control thoughts. Using hierarchical linear regression analyses such decreases significantly explained the variance in observed reductions in EAT-oral control and to a lesser extent, reductions in EAT-bulimia and food preoccupation and EAT-dieting. These results underscore the importance of metacognitive change in EDs and the potential utility of CBT-based treatment in its modification. Improving ED outcomes may warrant broadening the therapeutic target of over-control and a sense of loss of control beyond dysfunctional eating behaviors to include maladaptive metacognitions that concern the need to control thoughts.
