The impact of positive psychological personalities on employee's attitude and turnover intention

The hospitality and tourism industry is recognised as a potential service sector in contributing to the Malaysian economy and thoroughly associated with the hotel industry to sustain economic growth. One of the most significant problems for hotel managers is employee turnover. The issue of high voluntary turnover is a matter of grave concern at the national level that it is poorly affecting Malaysia's competitiveness. The present research investigates the impact of positive psychological personality traits in predicting employee's attitude towards the hotel industry and, consequently, reducing turnover intention. Data were collected from hotel employees in Malaysia (n = 200) and analysed using partial least structural equation modelling (Smart-PLS). Specific findings reveal that employee resilience, hope, and optimism increase employee's positive attitude towards the hotel industry and consequently reduce the turnover intention. This study has important implications for hotel managers interested in the determinants of employees' positive attitude towards hotels and employees' turnover intention in the hotel industry in Malaysia

Brand love impact on the social media and stages of brand loyalty

The primary objective of the current research is to propose and investigate a conceptual model which integrates social media activities and brand love as antecedents and brand loyalty phases as an outcome of brand love. The proposed model is analysed with a sample of 240 fast fashion’s consumers by using a self -structured questionnaire survey technique. PLS -SEM applied for statistical analysis to evaluate the hypnotized linkage between the variables. The results show that social internet marketing has a tremendous impact on brand love in the fast fashion profession. Furthermore, the finding shows that social media, has an indirect constructive effect on the various phases of brand loyalty through brand love. The current research supports the crucial role of social media in marketing and advertising which will assist internet marketers to fully realize brand love and loyalty behavior. The consequence of this particular study might assist marketers to develop the successful communication approach through social networking activities to shape good attitudes and advance brand loyalty, particularly in fast fashion profession

Curvature operators and scalar curvature invariants

We continue the study of the question of when a pseudo-Riemannain manifold can be locally characterised by its scalar polynomial curvature invariants (constructed from the Riemann tensor and its covariant derivatives). We make further use of alignment theory and the bivector form of the Weyl operator in higher dimensions, and introduce the important notions of diagonalisability and (complex) analytic metric extension. We show that if there exists an analytic metric extension of an arbitrary dimensional space of any signature to a Riemannian space (of Euclidean signature), then that space is characterised by its scalar curvature invariants. In particular, we discuss the Lorentzian case and the neutral signature case in four dimensions in more detail.Comment: 26 pages, 2 figure

Effects of different nutritional systems on seed germination and early seedling growth in medicinal pumpkin (Cucurbita pepo L.)

This study was carried out to determine the effect of different nutritional systems (chemical, biological and integrated) on germination and seedling growth in medicinal pumpkin (Cucurbita pepo L.). The statistical design was a randomized complete block design with four replications. Four levels of different fertilizing systems including chemical (T1), biological (a combination of nitrogen bacteria, Azospirillum brasilense and Glomus mosseae) (T2) and integrated fertilizing systems (biological fertilizer + 50% chemical fertilizer) (T3), and control (without fertilizer) (T0), were employed. The results indicated that the maximum seed germination was 95% and the highest seed germination rate with 30.4 per day was observed in the intergraded nutritional treatment. The experimental results showed that all nutritional treatments had positive effects on seed germination compared to control. The highest level of germination percentage with 95% and the highest rate of germination with 30.4 seeds per day were obtained in integrated nutritional treatment. However, the integrated nutritional system required more time to demonstrate its positive effect on the growth and yield of medicinal pumpkin compared to chemical system. The results of present experiment indicated that integrated nutritional treatment had the greatest positive impact on germination characteristics in medicinal pumpkin. Designing and developing such nutritional systems can guarantee and facilitate the achievement of long-term objectives of sustainable agriculture

Exposure assessment of process-related contaminants in food by biomarker monitoring

Exposure assessment is a fundamental part of the risk assessment paradigm, but can often present a number of challenges and uncertainties. This is especially the case for process contaminants formed during the processing, e.g. heating of food, since they are in part highly reactive and/or volatile, thus making exposure assessment by analysing contents in food unreliable. New approaches are therefore required to accurately assess consumer exposure and thus better inform the risk assessment. Such novel approaches may include the use of biomarkers, physiologically based kinetic (PBK) modelling-facilitated reverse dosimetry, and/or duplicate diet studies. This review focuses on the state of the art with respect to the use of biomarkers of exposure for the process contaminants acrylamide, 3-MCPD esters, glycidyl esters, furan and acrolein. From the overview presented, it becomes clear that the field of assessing human exposure to process-related contaminants in food by biomarker monitoring is promising and strongly developing. The current state of the art as well as the existing data gaps and challenges for the future were defined. They include (1) using PBK modelling and duplicate diet studies to establish, preferably in humans, correlations between external exposure and biomarkers; (2) elucidation of the possible endogenous formation of the process-related contaminants and the resulting biomarker levels; (3) the influence of inter-individual variations and how to include that in the biomarker-based exposure predictions; (4) the correction for confounding factors; (5) the value of the different biomarkers in relation to exposure scenario’s and risk assessment, and (6) the possibilities of novel methodologies. In spite of these challenges it can be concluded that biomarker-based exposure assessment provides a unique opportunity to more accurately assess consumer exposure to process-related contaminants in food and thus to better inform risk assessment

Evaluation and comparison of job stress among security workers with fixed and shift work schedules in Municipality of Tehran

Municipality of Tehran with huge number of employees and with the aim to reduce stress and promote the work efficiency, seriously wants to achieve suitable and utilizable studies. Osipow\u27s job stress test is one of the best tools to reach this aim. Data population includes securities building of municipality of Tehran (88 persons from region 18 and 72 persons from region 20), who were randomly chosen to be participated in the current survey. For this purpose three types of working hours schedule such as full time shift ( 24 hrs work, 24 hrs rest ), day-shift and night-shift workers, were selected. Data were analyzed by SPSS software and processed by a professional test, MANOVA. Difference of scores in workload role and insufficiency role in subjects with considering of age groups in confidence 95% was valuable (p\u3c0.05). Differences of scores in job stress and subscales of insufficiency role, ambiguity role with considering of work shifts in confidence 95% were statistically significant (p\u3c0.05). At the end, differences of scores in subscales of role rang and responsibility with considering of job regions in confidence 95% were statistically significant (p\u3c0.05).This survey determined that stress decreased with increasing the age. Also work shift had important role in the amount of stress. Therefore, the lowest level of stress was among night-shift workers and the highest stress level was among day-shift workers and 24-24 group was between them. Of course region of workers was related with job stress

Genomic structure of the luciferase gene from the bioluminescent beetle, Nyctophila cf. caucasica

The gene coding for beetle luciferase, the enzyme responsible for bioluminescence in over two thousand coleopteran species has, to date, only been characterized from one Palearctic species of Lampyridae. Here we report the characterization of the luciferase gene from a female beetle of an Iranian lampyrid species, Nyctophila cf. caucasica ( Coleoptera: Lampyridae). The luciferase gene was composed of seven exons, coding for 547 amino acids, separated by six introns spanning 1976 bp of genomic DNA. The deduced amino acid sequences of the luciferase gene of N. caucasica showed 98.9% homology to that of the Palearctic species Lampyris noctiluca. Analysis of the 810 bp upstream region of the luciferase gene revealed three TATA boxes and several other consensus transcriptional factor recognition sequences presenting evidence for a putative core promoter region conserved in Lampyrinae from -190 through to -155 upstream of the luciferase start codon. Along with the core promoter region the luciferase gene was compared with orthologous sequences from other lampyrid species and found to have greatest identity to Lampyris turkistanicus and Lampyris noctiluca. The significant sequence identity to the former is discussed in relation to taxonomic issues of Iranian lampyrids
