A Study on Hotel Service Quality Gaps

The service quality gap is a principal factor influencing the implementation of service quality strategy in hotels and the degree of guests' satisfaction. The research reveals the existence of different degrees of expectations and perceptions of service quality amongst hotel managers, the front-line staff and guests, and remarkable gaps between their expectations and perceptions of service quality, based on which an extended 12-gap model of hotel service quality gap is constructed in place of the traditional 5-gap model. Meanwhile, the authors propose that hotels should enhance market investigation and communication for the reduction and elimination of service quality gaps.
Leading Change Authentically

Organizational change has become complex and challenging, and employee attitudes and beliefs toward change are even more important. This article proposes a theoretical framework on how authentic leadership may influence followers’ change-oriented attitudes, beliefs, and behaviors through follower psychological resources including hope, trust, optimism, self-efficacy, and resilience, which influence readiness for change and change implementation. We maintain that an authentic leader’s behavior can influence his or her followers’ change-oriented behaviors in participation in decision-making processes and change initiatives, organization citizenship behavior, organizational learning processes, and forming coalition for change. We developed propositions for further empirical investigation.
Reappraisal of the removable partial denture as a treatment option for the shortened dental arch

For patients with shortened dental arches, many treatment options are available. The existing situation can be maintained by stabilizing the present dentition and improving the occlusion without extending the arch. Alternatively, the shortened dental arch can be extended by either a free-end saddle removable partial denture, cantilevered fixed bridge, or by an implant-supported prosthesis. The free-end saddle removable partial denture can be considered a simple, non-invasive, and relatively cheap treatment option for the shortened dental arch. It was believed that such prosthodontic rehabilitation would be beneficial for the patients in terms of improving oral functions. However, the existing literature indicates that the prognosis of free-end saddle removable partial denture is not predictable, it is problematic, and its contribution to oral functions in patients with shortened dental arches is considered to be dubious. This paper reviews and summarizes the current literature about the outcome of extending the shortened dental arch by a free-end saddle removable partial denture. It also outlines factors that may affect the prognosis of this prosthetic treatment.
Bayesian Estimation of the Probability of Asbestos Exposure from Lung Fiber Counts

Summary Asbestos exposure is a well‐known risk factor for various lung diseases, and when they occur, workmen's compensation boards need to make decisions concerning the probability the cause is work related. In the absence of a definitive work history, measures of short and long asbestos fibers as well as counts of asbestos bodies in the lung can be used as diagnostic tests for asbestos exposure. Typically, data from one or more lung samples are available to estimate the probability of asbestos exposure, often by comparing the values with those from a reference nonexposed population. As there is no gold standard measure, we explore a variety of latent class models that take into account the mixed discrete/continuous nature of the data, that each subject may provide data from more than one lung sample, and that the within‐subject results across different samples may be correlated. Our methods can be useful to compensation boards in providing individual level probabilities of exposure based on available data, to researchers who are studying the test properties for the various measures used in this area, and more generally, to other test situations with similar data structure.
The role of employee engagement in the relationship between job design and task performance, citizenship and deviant behaviours

The present study examined a potential mediator of the job design–performance relationship, namely employee engagement. Data were obtained via a survey of 283 employees in a consultancy and construction firm based in the UK and from supervisors' independent performance evaluations. The results reveal that employees who hold jobs that offer high levels of autonomy, task variety, task significance and feedback are more highly engaged and, in consequence, receive higher performance ratings from their supervisors, enact more organizational citizenship behaviours and engage in fewer deviant behaviours. Theoretical and practical implications are discussed.
Chronic Abdominal Pain in Children and Adolescents: Parental Threat Perception Plays a Major Role in Seeking Medical Consultations

Background. Pain symptoms, associated impairment, and parental perception of threat are reported to be predictors of health care utilization (HCU) in childhood chronic abdominal pain (CAP). However, mediating variables and their interrelations have not yet been systematically studied. Objectives. This study aims to identify mediating pathways of influence between child's abdominal pain and the number of pain-related medical visits. Methods. In a multicenter study, we recruited N = 151 parent-child dyads with children aged 6–17 years suffering from CAP. A composite measure of pain symptoms was defined as predictor and the number of pain-related medical visits as outcome variable. This relation was analyzed by serial mediation, including child- and parent-reported impairment and parental threat perception as mediators. Results. Only parental threat perception significantly linked child's pain symptoms to the number of medical visits. Measures of impairment did not have a significant effect. Conclusions. Parental pain-related threat perception is strongly related to health care seeking in childhood CAP. Addressing threat perception might be a fruitful parent-centered approach in clinical practice.
Upper limit for circumstellar gas around the type Ia SN 2000cx

Context. The nature of the companion stars in type Ia Supernova (SNe) progenitor systems remains unclear. One possible way to discriminate between different scenarios is the presence (or absence) of circumstellar material, the left overs from the progenitor evolution that may be revealed by their interaction with the SN. Aims. A new method to probe the circumstellar environment has been exploited for the normal type Ia SN 2006X, leading for the first time to the direct detection of material which escaped the progenitor system. In this paper we apply the same analysis to the peculiar type Ia SN 2000cx, with the aim of constraining the properties of its progenitor system. Methods. Using multi-epoch, high-resolution spectroscopy we have studied the spectral region where narrow, time-variable Na ID absorption features are expected in case circumstellar material is present along the line of sight. Results. No Na ID absorption is detected in the rest-frame of the host galaxy to a level of a few mA, setting a stringent upper limit to the column density of the absorbing material (N(NaI) 2 ≤ 10^(10) cm^(-2)). Conclusions. In this respect the peculiar type Ia SN 2000cx is different from the normal Ia SN 2006X. Whether this is to be attributed to a different progenitor system, to viewing-angle effects or to a low metallicity remains to be clarified.
An fMRI Study of Word Reading and Colour Recognition in Different Quadrant Fields

This fMRI study analyzed activations for processing of word and colour, which were presented in each of the four quadrants, to investigate anatomical segregation between colour and orientation processing and also to examine the effect of visual stimulus position on brain activations. Main effect of visual category was found in the bilateral extrastriate cortices extending to the left visual word form area (word > colour) and small area of the right ventrolateral prefrontal cortex (colour > word). ROI analysis showed that there was a tendency that V4α, not V4/8, showed a greater response to colours than to words. Main effect of visual fields was found in early visual areas, which showed greater responses to the left than to the right field stimuli and also to the lower than to the upper field stimuli. No significant interactions between visual category and visual fields were found.
The Influence of Semantics in Text Categorisation: A Comparative Study using the k Nearest Neighbours Method

In this paper we investigate dieren t uses of semantics in text categorisation tasks. At this end, we consider distinct representa- tions of documents which dier in the kind of information incorporated: a) information about terms only, b) semantic information (terms sense) and c) a combination of both types of information. Moreover, we study how the vocabulary size reduction aects this task. Thek Nearest Neigh- bours method was used to perform the categorisation and the vocabulary size was reduced by means of the Information Gain technique. A num- ber of dieren t document codications were tested. The experimental results showed that in corpora richer syntactically and semantically the inclusion of semantic information improves the text categorisation task if vocabularies with a sucien t number of features are considered.
Referential Hierarchies in Three-Participant Constructions in Vera'a

This paper 1 explores the relevance of referential hierarchies for different types of three-participant constructions in Vera'a, an endangered Oceanic language of North Vanuatu. In Vera'a, animacy, information structure and referential status of discourse participants interact in complex ways to influence the realization of goals/recipients in two different types of construction that both exhibit indirective argument alignment. The choice between a prepositional and a possessive-like construction is determined by semantic factors, namely whether a CAUSED MOTION or a CAUSED POSSESSION interpretation is intended. Referential hierarchies are relevant for the choice of referential expression for theme and goal/recipient arguments, and these different types of expression are amenable for different syntactic positions in each type of three-participant construction. Word order variation does, however, not bring about a change of alignment which is indirective in all possible constructional variants. This is even true for cases where a pronominal recipient argument is incorporated into the verbal predicate, resembling the realization of pronominal P arguments.

Explorations of Atmosphere–Ocean–Ice Climates on an Aquaplanet and Their Meridional Energy Transports

Abstract The degree to which total meridional heat transport is sensitive to the details of its atmospheric and oceanic components is explored. A coupled atmosphere, ocean, and sea ice model of an aquaplanet is employed to simulate very different climates—some with polar ice caps, some without—even though they are driven by the same incoming solar flux. Differences arise due to varying geometrical constraints on ocean circulation influencing its ability to transport heat meridionally. Without complex land configurations, the results prove easier to diagnose and compare to theory and simple models and, hence, provide a useful test bed for ideas about heat transport and its partition within the climate system. In particular, the results are discussed in the context of a 1978 study by Stone, who argued that for a planet with Earth’s astronomical parameters and rotation rate, the total meridional heat transport would be independent of the detailed dynamical processes responsible for that transport and depend .
Self-Presentational Congruence and Psychosocial Adjustment: A Test of Three Models

People regularly monitor and control the impressions others form of them but differ in the degree to which they both convey impressions that are consistent with their private self-views (self-presentational congruence) and present different images of themselves to different targets (self-presentational variability). This study examined the implications of self-presentational congruence and variability for psychological and social well-being. Participants rated the impressions that they tried to make on nine individuals in their lives and completed measures of psychosocial well-being. Results indicated that self-presentational congruence predicted psychosocial adjustment (higher subjective well-being, social support quality, social efficacy, and self-esteem; and lower anxiety, depression, and loneliness) beyond personality variables such as self-consciousness, fear of negative evaluation, and Machiavellianism. Self-presentational variability across targets also predicted better psychosocial adjustment, wit.
Effects of Array Size on Preschoolers’ Preference and Engagement: A Behavioral Translation of Choice Overload

Recent social psychology and consumer behavior research has suggested that an abundance of options in choice contexts can have detrimental effects on decision making—a phenomenon termed choice overload. This investigation sought to use behavior analytic procedures to examine the effects of numerous options on the toy preference of 3 preschoolers. Toy engagement was assessed under repeated free-operant arrangements in which participants accessed arrays of either 6 or 30 toys for 2 min. Results showed that relative to the 6-item array, preference for the most preferred item was diminished and preference for the 3 least preferred items were elevated with the 30-item array. Additionally, engagement with toys in the 30-item array tended to occur more frequently but for shorter durations, suggesting an overall decrease in the reinforcing value of each toy when presented in a larger array. A behavioral interpretation of choice overload is offered, as well as potential implications for research and practice.
Intra-cluster globular clusters around NGC 1399 in Fornax?

Aims. We investigate whether the globular clusters (GCs) in the recently published sample of GCs in the Fornax cluster by Bergond and coworkers are indeed intra-cluster objects. Methods. We combine their catalogue of radial velocity measurements with our CTIO MOSAIC photometry in the Washington system and analyse the relation of metal-poor and metal-rich GCs with their host galaxies. Results. The metal-rich GCs appear to be kinematically associated with their respective host galaxies. The vast majority of the metal-poor GCs found in between the galaxies of the Fornax cluster have velocities that are consistent with their being members of the very extended NGC 1399 GC system. We find that when the sample is restricted to the most accurate velocity measurements, the GC velocity dispersion profile can be described with a mass model derived for the NGC 1399 GC system within 80 kpc. We identify one “vagrant” GC whose radial velocity suggests that it is not bound to any galaxy unless its orbit has a very large apogalactic distance.
Predictive factors associated with the acceptance of pandemic and seasonal influenza vaccination in health care workers and students in Tuscany, Central Italy

Assessing the beliefs and attitudes of Health Care Workers (HCW) to influenza and influenza vaccination can be useful in overcoming low compliance rates. The purpose of our study is to evaluate the opinion of HCW and students regarding influenza, influenza vaccine and the factors associated with vaccination compliance. A survey was conducted between October 2010 and April 2011 in the Florence metropolitan area. A questionnaire was administered to HCW in three local healthcare units and at Careggi University Teaching Hospital. Students matriculating in health degree programs at Florence University were also surveyed. The coverage with vaccination against seasonal and pandemic influenza is generally low, and it is lower in students than in HCW (12.5% vs 15% for the seasonal vaccination, 8.5% vs 18% for the pandemic vaccination). Individuals comply with vaccination offer mainly to protect themselves and their contacts. Individuals not receiving vaccination did not consider themselves at risk, had never been vaccinated before or believed that pandemic influenza was not a public health concern. Physicians had the highest compliance to vaccination and women were less frequently vaccinated than men. HCW do not appear to perceive their possible influenza infections as a risk for patients: HCW receive vaccination mainly as a form of personal protection. Low compliance to vaccination is determined by various factors and therefore requires a multi-faceted strategy of response. This should include short-term actions to overcome organizational barriers, in addition to long-term interventions to raise HCW’s level of knowledge about influenza and influenza vaccination.
The PersonaCheck System for Personalizing M-Commerce Checkout Processes

This demonstration paper presents a Web-based adaptive interactive system for personalizing the checkout process of M-Commerce Web environments, coined Persona Check. In particular, the system personalizes the visual and interaction design aspects of a mobile Web-based checkout process based on users' cognitive style theory which argues that individuals have differences in the way they process and organize information, as well as experience their context and environment in different manners and perspectives. The Persona Check system consists of three main components: i) an M-Commerce environment for creating and managing the checkout process designs, ii) a user modeling component in which explicit user data collection methods are performed for eliciting the users' cognitive processing characteristics, and iii) an adaptive user interface that is responsible for performing rule-based mechanisms for deciding and communicating the "best-fit" checkout process design to the users based on their cognitive styles.
Determinants of athletes’ moral competence: the role of demographic characteristics and sport-related perceptions

Abstract The aim of the present study was to examine whether demographic characteristics and perceptions regarding sport-ability and sport-league affect one’s moral competence. A total of 685 athletes from five different sports participated in the study. The moral competence test was used, in order to assess players’ moral competence. Also, players’ sport-related perceptions and demographic data were reported. The ANOVAs revealed that athletes of individual sports and sports with no and/or low physical contact scored significantly higher in moral competence compared to team sport athletes who compete in high-contact sports. Moreover, players’ age, education, sport experience and perceived sport ability were found to play a significant role in moral development, while their level of competition, and gender did not have a significant effect on their morality. Overall, results demonstrated that several demographic characteristics and sport-related perceptions should be taken into account when interpreting ones’ moral profile.
Joint Modeling of User Check-in Behaviors for Real-time Point-of-Interest Recommendation

Point-of-Interest (POI) recommendation has become an important means to help people discover attractive and interesting places, especially when users travel out of town. However, the extreme sparsity of a user-POI matrix creates a severe challenge. To cope with this challenge, we propose a unified probabilistic generative model, the Topic-Region Model (TRM), to simultaneously discover the semantic, temporal, and spatial patterns of users’ check-in activities, and to model their joint effect on users’ decision making for selection of POIs to visit. To demonstrate the applicability and flexibility of TRM, we investigate how it supports two recommendation scenarios in a unified way, that is, hometown recommendation and out-of-town recommendation. TRM effectively overcomes data sparsity by the complementarity and mutual enhancement of the diverse information associated with users’ check-in activities (e.g., check-in content, time, and location) in the processes of discovering heterogeneous patterns and producing recommendations. To support real-time POI recommendations, we further extend the TRM model to an online learning model, TRM-Online, to track changing user interests and speed up the model training. In addition, based on the learned model, we propose a clustering-based branch and bound algorithm (CBB) to prune the POI search space and facilitate fast retrieval of the top-k recommendations. We conduct extensive experiments to evaluate the performance of our proposals on two real-world datasets, including recommendation effectiveness, overcoming the cold-start problem, recommendation efficiency, and model-training efficiency. The experimental results demonstrate the superiority of our TRM models, especially TRM-Online, compared with state-of-the-art competitive methods, by making more effective and efficient mobile recommendations. In addition, we study the importance of each type of pattern in the two recommendation scenarios, respectively, and find that exploiting temporal patterns is most important for the hometown recommendation scenario, while the semantic patterns play a dominant role in improving the recommendation effectiveness for out-of-town users.
Effect of Neem Leaf Extract (Azadirachta indica) on c-Myc Oncogene Expression in 4T1 Breast Cancer Cells of BALB/c Mice

Objective: Breast cancer is the most common cause of cancer-related deaths in women both worldwide and in Malaysia. Azadirachta indica (A. Juss), commonly known as neem, is one of the most versatile medicinal plants that has gained worldwide prominence due to its medicinal properties. However, the anticancer effect of ethanolic neem leaf extract against breast cancer has not been documented. The purpose of the present study is to investigate the effect of neem leaf extract on c-Myc oncogene expression in 4T1 breast cancer BALB/c mice. Materials and Methods: In this experimental study, A total of 48 female BALB/c mice were divided randomly into four groups of 12 mice per group: i.cancer control (CC) treated with 0.5% Tween 20 in PBS, ii. 0.5 µg/mL tamoxifen citrate (CT), iii. 250 mg/kg neem leaf extract (C250), and iv. 500 mg/kg neem leaf extract (C500). in situ reverse transcription polymerase chain reaction (in situ RT-PCR) was applied to evaluate suppression of c-Myc oncogene expression in breast cancer tissue. Results: The C500 group showed significant (p<0.05) suppression of c-Myc oncogene expression compared to the CC group. Conclusion: c-Myc was found to be down regulated under the effect of 500 mg/kg ethanolic neem leaf extract.
