The Interaction Effect of Accounting Information Systems User Satisfaction and Activity-Based Costing Use on Hotel Financial Performance: Evidence from Greece

The interaction of Information Technology (IT) and contemporary management accounting systems is an emerging research area. This paper aims at exploring the interaction effect of Accounting Information Systems (AIS) user satisfaction and Activity-Based Costing (ABC) use on hotel financial performance. We empirically test the above relationship in Greek hotel industry, because its highly competitive and information-intensive nature is characterized by the necessity for useful and accurate cost accounting information. Using hierarchical regression analysis, results suggest that when ABC use interacts with AIS user satisfaction, hotel financial performance is improved. On the contrary, AIS user satisfaction and ABC use have no significant association with financial performance when they act independently. This study fills a gap in the literature by developing a new framework that combines IS user satisfaction theory (IS Success Model) and contemporary management accounting techniques. Moreover, it underlines the role of AIS user satisfaction as an enabler of ABC. Finally, our findings extend the hospitality accounting literature, since empirical research on ABC is limited in the hotel industry.
EMME . ir 1 Balancing Unicycle Travelling on an Inclined Surface Erfan

A self-balancing unicycle robot is equipped with roll stabilizing unit and a wheel which is in charge of simultaneous unicycle frame upright holding and path tracking. Linear quadratic regulators (LQR) are designed for the roll, pitch and path tracking to make the vehicle successfully perform its desired operations. Even though control loops in general and LQR in specific subdue disturbances such as road slope, still some extra strong measures may be required. The road tilt alters the device dynamic and exerts forces influencing its behavior against reference commands. In this respect, gain scheduling LQR is designed and its impact on the system performance with regard to the conventionally designed LQR is discussed. Simulation results are used to validate the propositions.

Policy incentives for private innovation and maximising the returns

This paper uses panel regression techniques to assess the policy determinants of private-sector innovative activity – proxied by R&D expenditure and the number of new patents – across 19 OECD countries. The relationship between innovation indicators and multifactor productivity (MFP) growth is also examined with a particular focus on the role of public policies in influencing the returns to new knowledge. The results establish an empirical link between R&D and patenting, as well as between these measures of innovation intensity and MFP growth. Innovation-specific policies such as R&D tax incentives, direct government support and patent rights are found to be successful in encouraging the innovative activities associated with higher productivity growth. However, direct empirical evidence of the positive effects of these policies on productivity is less forthcoming. A pervasive theme from the analysis is the importance of coupling policies aimed at encouraging innovation or technological adoption with well-designed framework policies that allow knowledge spillovers to proliferate. In particular, the settings of framework policies relating to product market regulation, openness to trade and debtor protection in bankruptcy provisions are found to be important for the diffusion of new technologies.

Exploring customer satisfaction with university cafeteria food services. An empirical study of Temptation Restaurant at Taylor’s University, Malaysia

Abstract This study investigates the link between the different service characteristics that have an influence on customer satisfaction in university cafeteria food services. A conceptual model comprising of different variables like food and beverage quality, service quality, food choice, price and value equality, and ambience were studied for customer satisfaction to explore the relationship among them. This study examined how dining experiences influence the satisfaction and loyalty of both non-mature (students) and mature (staff) customers, in order to find their similarities and differences within the context of university cafeteria services. The study was conducted at Taylor’s University in Malaysia by using a quantitative research approach, and 231 students and 63 staff members of the university participated in the study. The findings reveal that the various quality factors considered in the study are positively correlated with customer satisfaction and have a significant impact on the satisfaction level of both students and staff who dined at the university cafeteria. It could be concluded from the results that the influence of price offered at the university cafeteria had a significant effect on respondents’ loyalty. The result of this study offers a direction towards better the services and facilities, which lead to an increase of the competitive influence of the restaurant business in the marketplace.
On a discretizable subclass of instances of the molecular distance geometry problem

The molecular distance geometry problem can be formulated as the problem of finding an immersion in R3 of a given undirected, nonnegatively weighted graph G. In this paper, we discuss a set of graphs G for which the problem may also be formulated as a combinatorial search in discrete space. This is theoretically interesting as an example of "combinatorialization" of a continuous nonlinear problem. It is also algorithmically interesting because the natural combinatorial solution algorithm performs much better than a global optimization approach on the continuous formulation. We present a Branch and Prune algorithm which can be used for obtaining a set of positions of the atoms of protein conformations when only some of the distances between the atoms are known.
Influence of Leadership Styles on Self Performance

The study investigated the leadership styles of the workers and their performances as well, in the Chittoor Sugar factory located at the Chittoor town of South India. The influence of the worker's own leadership style on the self performance was also investigated. The study mainly concentrated on the three interesting leadership styles that are at the top, bottom and the middle of the leadership authority hierarchy, namely the autocratic, the laissez-faire and democratic leadership styles. Upon study it has been found that workers with autocratic leadership style give more performance against others. Keywords: workers, leadership styles, autocratic, democratic, laissez-faire, performance.
Female households and poverty: A case study of Faisalabad District

This study shows the relationship between female-headed households, male household and poverty in the two Tehisils of District Faisalabad. Eighty response clients were interviewed. Compare means; regressions and the binary Logit regressions analysis are used to detect the relationship between female household, male household and the factors that affect the possibility towards poverty. Linear results indicate that education, secondary earners, number of children and occupations are the significant factors that affect monthly income of the family. Nevertheless, results indicate that income, consumption, family size and households headship status, play vital role to determine the level of poverty. There is negative relationship between head of households and poverty. Female household’s heads have fewer assets, lower earning capacity than male-headed. Results suggest that the need for special interventions, skilled knowledge and specific infrastructures are required for the improvement women community.
Effective Denoising and Adaptive Equalization of Indoor Optical Wireless Channel With Artificial Light Using the Discrete Wavelet Transform and Artificial Neural Network

Indoor diffuse optical wireless (OW) communication systems performance is limited due to a number of effects; interference from natural and artificial light sources and multipath induced intersymbol interference (ISI). Artificial light interference (ALI) is a periodic signal with a spectrum profile extending up to the MHz range. It is the dominant source of performance degradation at low data rates, which can be removed using a high-pass filter (HPF). On the other hand, ISI is more severe at high data rates and an equalizing filter is incorporated at the receiver to compensate for the ISI. This paper provides the simulation results for a discrete wavelet transform (DWT)-artificial neural network (ANN)-based receiver architecture for on-and-off keying (OOK) non-return-to-zero (NRZ) scheme for a diffuse indoor OW link in the presence of ALI and ISI. ANN is adopted for classification acting as an efficient equalizer compared to the traditional equalizers. The ALI is effectively reduced by proper selection of the DWT coefficients resulting in improved receiver performance compared to the digital HPF. The simulated bit error rate (BER) performance of proposed DWT-ANN receiver structure for a diffuse indoor OW link operating at a data range of 10-200 Mbps is presented and discussed. The results are compared with performance of a diffuse link with an HPF-equalizer, ALI with/without filtering, and a line-of-sight (LOS) without filtering. We show that the DWT-ANN display a lower power requirement when compared to the receiver with an HPF-equalizer over a full range of delay spread in presence of ALI. However, as expected compared to the ideal LOS link the power penalty is higher reaching to 6 dB at 200 Mbps data rate.
Credit Constraints and Macroeconomic Instability in a Small Open Economy

This paper presents a dynamic model for a small open economy with imperfect financial market. It provides a framework to analyze the role of credit constraints and debt denomination in the generation and amplification of macroeconomic instability in an open economy context. As in Bernanke and Gertler (1989), the imperfection in the financial market results from the existence of a costly state of verification (CSV) problem. Entrepreneurs whose net worth is not enough to finance their desired physical investment have to pay a premium above the risk-free interest rate to obtain external funds. Other key ingredients of the model are that a foreign good is used as an input in the production of the capital good, and that the debt is denominated in terms of the foreign good. Real exchange rate depreciations generate an increase in the cost of producing capital and a reduction in the net worth of entrepreneurs due to the debt denomination. Therefore, recessionary effects can be deepened. ∗I am indebted to Mark Gertler and Andrés Velasco for their valuable advice. I also thank William Baumol, Michele Cavallo and Boyan Jovanovic for their useful comments. Of course, all errors are mine.
Chronic Poverty in the United States

This paper proposes a method of measuring chronic and transitory poverty using an axiomatically sound, additively decomposable index of aggregate poverty. Our approach is contrasted with alternative methods of measuring poverty persistence. We use our method to measure chronic and transitory poverty in the United States during the 1980s and late 1970s and find that chronic poverty is a more serious problem than previously thought. Between the late 1970s and mid 1980s poverty not only increased, it became more chronic and less transitory in nature. This is true for the population as a whole and for some, but not all, of the subpopulations we considered. The latter were defined according to race, type of social unit, and educational qualifications of the head of the social unit. All empirical analyses are based on data from the Panel Study of Income Dynamics.
Abuse-Specific Self-Schemas and Self-Functioning: A Prospective Study of Sexually Abused Youth

Potential pathways from childhood sexual abuse (CSA) to negative self-schemas to subsequent dissociative symptoms and low global self-esteem were examined in a prospective longitudinal study of 160 ethnically diverse youth with confirmed CSA histories. Participants were interviewed at the time of abuse discovery, when they were 8 to 15 years of age, and again 1 and 6 years later. Abuse-specific indicators of stigmatization, in particular the combination of shame and self-blame more than general self-blame attributions for everyday events, explained which youth with CSA histories experienced more dissociative symptoms and clinically significant levels of dissociation. Abuse-specific stigmatization was found to operate as a prospective mechanism for subsequent dissociative symptoms but not self-esteem.
SEMINAR FOR PHYSICIANS

The progress in the field of early diagnosis and cancer treatment in the past few decades has led to a significant decrease in mortality rate of cancer patients, whereas the quality of their lives has significantly deteriorated. Taking into consideration that cancer treatment requires aggressive methods, which are exceptionally difficult for patients and affect their social and emotional lives and behavior, the focus is on preserving the overall integrity of the person, rehabilitation and return to their families and social life [1]. Despite the increase of long-term survival of cancer patients, cancer treatment, including chemotherapy, radiotherapy and surgical treatment methods, can contribute to a decrease of fertility in both genders. Considering the increasing number of surviving young patients, there is a need to introduce the term oncofertility, which means preservation of fertility in cancer patients after treatment [2]. Infertility induced by cancer treatment decreases the quality of life of surviving patients in the reproductive age, and leads to a long-term emotional stress, especially among patients who did not get relevant information about the possibilities and ways of fertility preservation before treatment initiation [3]. The aim of this paper is to present current options and techniques for fertility preservation in cancer patients.
Music, bodies and relationships: An ethnographic contribution to embodied cognition studies

This article sets out the methodology and results of part of an ethnographic study of North Indian music performance where qualitative interviews were analyzed with grounded theory to explore how musicians conceive of musical communication. The findings highlight the importance of socially-responsive movement cues that musicians use to co-ordinate their participation in musical events. Effective musical communication, as explored in this article, is seen to depend on the manifestation and maintenance of the relationships between participants. This analytical attention to the moment-by-moment processes of interaction that musicians must engage in chimes with current enactive approaches to cognition. The article concludes by discussing the role of music research in the development of such work, suggesting that empirical research into music as social interaction could provide important insights for an enactive understanding of human cognition.
Ethanol Induces Fatty Acid Synthesis Pathways by Activation of Sterol Regulatory Element-binding Protein (SREBP)*

Alcoholic fatty liver is the earliest and most common response of the liver to alcohol and may be a precursor of more severe forms of liver injury. The mechanism by which ethanol causes fatty liver and liver injury is complex. We found that in both rat H4IIEC3 and McA-RH7777 hepatoma cell lines, ethanol induced transcription of a sterol regulatory element-binding protein (SREBP)-regulated promoter via increased levels of mature SREBP-1 protein. This effect of ethanol was blocked by addition of sterols. This effect is likely mediated by acetaldehyde, because the effect was only seen in cell lines expressing alcohol dehydrogenase, and inhibition of ethanol oxidation by 4-methylpyrazole blocked the effect in the hepatoma cells. Furthermore, the aldehyde dehydrogenase inhibitor cyanamide enhanced the effect of ethanol in the hepatoma cells. Consistent with these in vitro findings, feeding mice a low fat diet with ethanol for 4 weeks resulted in a significant increase in steady-state levels of the mature (active) form of SREBP-1. Activation of SREBP-1 by ethanol feeding was associated with increased expression of hepatic lipogenic genes as well as the accumulation of triglyceride in the livers. These finding suggest that metabolism of ethanol increased hepatic lipogenesis by activating SREBP-1 and that this effect of ethanol may contribute to the development of alcoholic fatty liver.
Performance of Eleven Simplified Methods for the Identification of Elevated Blood Pressure in Children and Adolescents

The identification of elevated blood pressure (BP) in children and adolescents relies on complex percentile tables. The present study compares the performance of 11 simplified methods for assessing elevated or high BP in children and adolescents using individual-level data from 7 countries. Data on BP were available for a total of 58 899 children and adolescents aged 6 to 17 years from 7 national surveys in China, India, Iran, Korea, Poland, Tunisia, and the United States. Performance of the simplified methods for screening elevated or high BP was assessed with receiver operating characteristic curve (area under the curve), sensitivity, specificity, positive predictive value, and negative predictive value. When pooling individual data from the 7 countries, all 11 simplified methods performed well in screening high BP, with high area under the curve values (0.84–0.98), high sensitivity (0.69–1.00), high specificity (0.87–1.00), and high negative predictive values (≥0.98). However, positive predictive value was low for most simplified methods, but reached ≈0.90 for each of the 3 methods, including sex- and age-specific BP references (at the 95th percentile of height), the formula for BP references (at the 95th percentile of height), and the simplified method relying on a child’s absolute height. These findings were found independently of sex, age, and geographical location. Similar results were found for simplified methods for screening elevated BP. In conclusion, all 11 simplified methods performed well for identifying high or elevated BP in children and adolescents, but 3 methods performed best and may be most useful for screening purposes.
Supervision: Using the evidence to support our practice.

The function of supervision is to make people safe, quality practitioners. They feel able to do the job to the best of their ability and to give their clients the maximum service they can within a cost-effective system and the confines of their service delivery. (Ormond, 2004) Supervision is an activity that, when effective, contributes significantly to service delivery and the ongoing learning and development of staff. Conversely, an organisation dedicating considerable time to an activity that is not benefiting practitioners and clients actually detracts from direct service provision. A national supervision project was commenced in October 2004 to maximise the effectiveness of supervision in the Ministry of Education – Special Education (GSE). One of the goals of this project was to develop a national supervision framework outlining thekey indicators of effective supervision. A reference group was formed of thirteen staff spread across regions, tiers of the organisation, occupational groups and cultural perspectives, as well as extent of experience with GSE and with supervision. The group took an evidence-based approach to the project, with the term “supervision” encompassing professional, clinical and cultural supervision. This evidence-based approach was conceptualised as the intersection between the research evidence, practitioner expertise and the lived experiences of the people involved. Therefore, information was gathered from three main sources: a literature review (the research evidence), interviews with twelve luminaries in the field of supervision (practitioner expertise) and an internal online survey (the lived experience of the people involved). Additionally, reference group members scoped existing supervision practices in their districts and regions. The online survey, which had a response rate of nearly 40 percent, gathered a variety of quantitative and qualitative information on the current practices of staff in relation to supervision. Results from the survey, enhanced with information from districts, were used to develop a snapshot of supervision within the organisation. This snapshot was examined against the effective practices outlined by the literature and key luminaries, and informed the development of GSE’s national supervision framework. This article seeks to synthesise the evidence underpinning each of the key themes, examine them against the current picture of supervision with GSE and translate them into practical ways of enriching supervision practices. Supervision helps a person reach their highest potential in their work and personal life. (Ormond, 2004)
University ’ s repository of research publications and other research outputs Locating bugs without looking back Journal Item

Bug localisation is a core program comprehension task in software maintenance: given the observation of a bug, e.g. via a bug report, where is it located in the source code? Information retrieval (IR) approaches see the bug report as the query, and the source code files as the documents to be retrieved, ranked by relevance. Such approaches have the advantage of not requiring expensive static or dynamic analysis of the code. However, current state-of-the-art IR approaches rely on project history, in particular previously fixed bugs or previous versions of the source code. We present a novel approach that directly scores each current file against the given report, thus not requiring past code and reports. The scoring method is based on heuristics identified throughmanual inspection of a small sample of bug reports.We compare our approach to eight others, using their own five metrics on their own six open source projects. Out of 30 performance indicators, we improve 27 and equal 2. Over the projects analysed, on average we find one or more affected files in the top 10 ranked files for 76% of the bug reports. These results show the applicability of our approach to software projects without history. This is a substantially extended version of our previous 4-page paper (Dilshener et al. 2016). We have added 2 research questions, analysed 2 more projects (Pillar1 and Pillar2), and compared against 3 more approaches (Wong et al. 2014; Youm et al. 2015; Rahman et al. 2015). Sections 4 and 5 are new (except 4.1.3 and 4.1.4) and existing sections have been considerably expanded with new material.

Effect of Sexual Hormones on the Electroencephalogram and Seizures

The role of hormones and reproductive function in electroencephalography (EEG) and epilepsy has long intrigued electroencephalographers. In this report, the relationship between the menstrual cycle and pregnancy and EEG changes and seizure frequency is reviewed. These neurophysiologic changes are likely secondary to hormonal effects. The effect of these hormones on experimental animal models is also reviewed.
