How may I help you? behavior and impressions in hospitality service encounters

In the service industry, customers often assess quality of service based on the behavior, perceived personality, and other attributes of the front line service employees they interact with. Interpersonal communication during these interactions is key to determine customer satisfaction and perceived service quality. We present a computational framework to automatically infer perceived performance and skill variables of employees interacting with customers in a hotel reception desk setting using nonverbal behavior, studying a dataset of 169 dyadic interactions involving students from a hospitality management school. We also study the connections between impressions of Big-5 personality traits, attractiveness, and performance of receptionists. In regression tasks, our automatic framework achieves R2=0.30 for performance impressions using audio-visual nonverbal cues, compared to 0.35 using personality impressions, while attractiveness impressions had low predictive power. We also study the integration of nonverbal behavior and Big-5 personality impressions towards increasing regression performance (R2 = 0.37).
Quality Of Disclosure And Corporate Social Responsibility Reporting Practices In Indonesia

This research aims to analyze the influence of corporate social responsibility (CSR) reporting practices on CSR disclosure quality in Indonesia. This research used a sample of 103 companies across industries (except for natural resource companies) listed on Indonesian Stock Exchange from 2014 to 2016. This research found thatthe voluntary practice of stand-alone report, assurance and reporting guideline does not enhance the quality of disclosure.This practices tend to be usedas symbolic approach to fulfillcompanies legitimacy. This symbolic approach has the meaning that the companieswhich voluntarily disclose theirCSR information, merely aiming a positive impression from their stakeholders.Companies tend to disclose CSR information by diluting the relevant CSR information with unnecessary information to build their desired images.
Trust-enabling decision support system for e-tourism intermediation

We present a trust-enabling intermediation system architecture for intelligent decision support in e-tourism applications, namely the Trust Intermediary Service Provider (TISP) system. The purpose of the present work is twofold: to propose a trust-building conceptual framework to account for customer trust in e-commerce applications; and to present a system architecture for knowledge-based decision-making support in the e-tourism context, as a technological demonstration fitting most of the trust-enabling mechanisms in the conceptual framework. The presented system aims to demonstrate the technological feasibility of a semantic-web-based architecture capable of meeting personalised needs and interests in interacting with an e-tourism intermediary, while allowing mechanisms to support trust building and maintenance. The core TISP components are designed for high reusability and are based on advanced knowledge-management-enabling technologies as well as design patterns derived from the Semantic Web (SW) and artificial intelligence fields of study.
Laparoscopic Wide Mesocolic Excision and Central Vascular Ligation for Carcinoma of the Colon

Background and Aims: The principle of complete mesocolic excision for colon cancer has been introduced to improve oncologic outcome. However, this approach is scantily discussed for laparoscopic surgery and there is a lack of randomized trials. This study examined oncologic and clinical outcome after laparoscopic wide mesocolic excision and central vascular ligation for colon cancer. Material and Methods: This is a review of prospectively gathered data from a single-institution colorectal cancer database. This study was conducted in the Central Hospital of Central Finland. From January 2003 to December 2011, 222 patients underwent laparoscopic colonic resections with wide mesocolic excision and central vascular ligation in the multimodal setting. The main measures of outcome were cancer recurrence and survival, with early recovery, 30d-mortality and morbidity, reoperation, readmission, and late complications as secondary outcomes. Results: The median follow-up was 5.5 (interquartile range (IQR) = 3.7–8.0) years. The 5-year overall survival for all 222 patients was 80.2% and disease-specific survival was 87.5%, and for those 210 R0-patients with stage I–III disease, 83.9% and 91.3%, respectively. The 5-year disease-free survival was 85.8%: stage I was 94.7%, stage II was 90.8%, and stage III was 75.6% (p = 0.004). Increasing lymph node ratio significantly decreased the 5-year disease-free survival. Conversion rate to open surgery was 12.2%. Thirty-day mortality was 1.3% and morbidity, 19.7%. Median postoperative hospital stay was 5 (IQR = 3–7) days. Conclusion: Laparoscopic wide mesocolic excision and central vascular ligation for colon cancer resulted in good long-term oncologic outcome. Randomized trials are needed to show that laparoscopic complete mesocolic excision technique would become the standard of care for the carcinoma of the colon.
Use of a Mixture of Bacteriophages for Biological Control of Salmonella enterica Strains in Compost

ABSTRACT Bacteriophages specific to Salmonella strains were isolated from sewage effluent and characterized. A five-strain bacteriophage mixture was applied to dairy manure compost inoculated with Salmonella enterica serotype Typhimurium. Bacteriophage treatment resulted in a greater than 2-log-unit reduction of Salmonella within 4 h at all moisture levels compared to the controls.
ECG monitoring of a car driver using capacitively-coupled electrodes

Many reports show that there are a lot of traffic accidents due to sleeping while driving. Then, demand for measuring electrocardiogram (ECG) to estimate drowsiness of drivers has increased to prevent these accidents. In this paper, we propose an ECG monitoring system of a car driver using capacitively-coupled electrode. This capacitively-coupled electrode on which an operational amplifier (OP amp) was mounted was embedded inside a seat for measuring ECG signal. A ground electrode was placed on a steering wheel, i.e. ECG signal was amplified by a single-ended amplifier. Subjects wore their regular suits and pants made of wool, and ECG was obtained during driving at low speed on a rough road with one corner. Results show that our system can be used to obtain ECG while driving at low speed except some motion artifacts caused by the steering operation, road surface, braking, and accelerating.
The Comparison of Pre-Competition Anxiety and State Anger between Female and Male Volleyball Players

2 Abstract: The main purpose of this study was to compare pre-competition anxiety and state anger between female and male volleyball players (university students). The statistical population consisted of all male and female volleyball players (n=214) who participated in Iran volleyball university matches. It must be noted that the questionnaires were distributed among whole statistical population either 30 minutes before competition started in the hall where competition was supposed to be held or at the time the athletes went to the hall to start the competition and finally 88 questionnaires were collected from male volleyball players and 82 questionnaires were collected from female ones. In this research, the CSAI-2R questionnaire was used to measure cognitive state anxiety, somatic state anxiety and self-confidence on a scale ranging from 1 = not at all to 4 = very much so in a competitive setting. The State-Trait Anger Expression Inventory (STAXI; Spielberger, 1991) was also used to provide a measure of the anger experience as an emotional state (state anger), the disposition towards anger as a personality trait (trait anger) and the expression of anger. K-S (P=0.05) was used to ascertain data normality. Descriptive statistics (mean, standard error), t test and Pearson coefficient were used to analyze the data (P=0.05). The results showed a significant difference in all pre-competition anxiety subscales: cognitive state anxiety (t=3.62), somatic state anxiety (t=4.76) and self-confidence (t=3.06) (P=0.05). Although there was no significant difference in trait anger (t=1.41, sig>0.05), there was a significant difference in state anger (t=2.15) and the expression of anger (3.67) (P=0.05).
DOES EVOLUTIONARY PLASTICITY EVOLVE?

During the development of a multicellular organism from a zygote, a large number of epigenetic interactions take place on every level of suborganismal organization. This raises the possibility that the system of epigenetic interactions may compensate or “buffer” some of the changes that occur as mutations on its lowest levels, and thus stabilize the phenotype with respect to mutations. This hypothetical phenomenon will be called “epigenetic stability. ” Its potential importance stems from the fact that phenotypic variation with a genetic basis is an essential prerequisite for evolution. Thus, variation in epigenetic stability might profoundly affect attainable rates of evolution. While representing a systemic property of a developmental system, epigenetic stability might itself be genetically determined and thus be subject to evolutionary change. Whether or not this is the case should ideally be answered directly, that is, by experimentation. The time scale involved and our insufficient quantitative understanding of developmental pathways will probably preclude such an approach in the foreseeable future. Preliminary answers are sought here by using a biochemically motivated model of a small but central part of a developmental pathway. Modeled are sets of transcriptional regulators that mutually regulate each other's expression and thereby form stable gene expression patterns. Such gene‐expression patterns, crucially involved in determining developmental pattern formation events, are most likely subject to strong stabilizing natural selection. After long periods of stabilizing selection, the fraction of mutations causing changes in gene‐expression patterns is substantially reduced in the model. Epigenetic stability has increased. This phenomenon is found for widely varying regulatory scenarios among transcription factor genes. It is discussed that only epistatic (nonlinear) gene interactions can cause such change in epigenetic stability. Evidence from paleontology, molecular evolution, development, and genetics, consistent with the existence of variation in epigenetic stability, is discussed. The relation of epigenetic stability to developmental canalization is outlined. Experimental scenarios are suggested that may provide further evidence.
Intranasal cooling with or without intravenous cold fluids during and after cardiac arrest in pigs

Background: Intranasal balloon catheters circulated with cold saline have previously been used for the induction and maintenance of selective brain cooling in pigs with normal circulation. In the present study, we investigated the feasibility of therapeutic hypothermia initiation, maintenance and rewarming using such intranasal balloon catheters with or without addition of intravenous ice‐cold fluids during and after cardiac arrest treatment in pigs.
Prioritizing Geographical based Communication Oriented Risks and Associated Mitigation Strategies of Global Software Development

The global software paradigm brings many opportunities but with some complicated challenges. The most influential drivers behind these challenges are temporal distances, socio-cultural differences and geographical distances. Due to these challenges the communication, coordination and control issues arise. These issues badly affect the quality level, cost and schedule of the project. Due to these issues the risk management process becomes more complicated as compare to traditional software engineering. In this study a frame work will be presented to quantify the relative importance of communication oriented risks and corresponding mitigation strategies. An MCDM approach will be employed in order to deal with conflictive, multi-criterion situations and also subjective expert judgments.
Speechreading and its association with reading among deaf, hearing and dyslexic individuals

Reading and speechreading are both visual skills based on speech and language processing. Here we explore individual differences in speechreading in profoundly prelingually deaf adults, hearing adults with a history of dyslexia, and hearing adults with no history of a literacy disorder. Speechreading skill distinguished the three groups: the deaf group were better speechreaders than hearing controls, who were better than the group with a history of dyslexia. The dyslexic group, while within range of hearing controls in terms of reading, nevertheless showed a residual deficit in speech/language processing when tested with silent speech. Within‐group correlations suggested different associations between speechreading subtasks, reading and language skills. In particular, in the deaf and dyslexic groups, but not in the hearing controls, speechreading skill correlated with reading ability.
Androgen receptors in the embryonic zebra finch hindbrain suggest a function for maternal androgens in perihatching survival

Bird embryos are exposed to maternal androgens deposited in the egg, but the role of these hormones in embryonic development and hatchling survival is unclear. To identify possible target organs, we used in situ hybridization to study the distribution of androgen receptor (AR) RNA in the developing zebra finch brain. The first brain expression domain of AR mRNA is in the hindbrain. From embryonic day 7 (E7) onward, when the hypoglossal motor nucleus (nXII) has just formed, there was AR mRNA expression in both its lingual (nXIIl) and its tracheosyringeal (nXIIts) parts, and this was the major site of hindbrain expression at all embryonic stages and in both sexes. From E8 onward, we also found AR mRNA in the supraspinal motor nucleus (nSSp), which innervates neck muscles. Furthermore, the syrinx, the target of the nXIIts, contained AR mRNA by E10, localized principally in the perichondria. Muscle was first evident in the syringeal region at E9, but no AR was detected in syringeal muscles until after hatching. The expression pattern of AR in the zebra finch embryo suggests that maternal androgens act via AR in the brainstem and syrinx to influence hatching as well as acoustic and visual components of food‐begging behavior. Maternal androgens seem unlikely to function in the development of sexual dimorphisms in the zebra finch nXIIts and syrinx, insofar as these are not evident until between 10 and 20 days posthatching.

Developing the partner relationship management system for franchised electronic stores

The internet age and e-business have not only modified the way enterprises see its customers but have also brought some significant changes to the way enterprises interact with each other. The purpose of this study is to develop a Partner Relationship Management (PRM) system to fit the partner management process and to provide necessary tools focusing on the characteristics of franchising e-stores, which can improve partner relationship in the Franchising Electronic Store Model (FESM). The functions of the PRM system were derived after reviewing the related literature. The PRM system comprises six modules: partner management, partner training, sales management, collaborative procurement, marketing information sharing and business operating know-how. Through empirical testing, the study also provides evidence that all modules of the PRM system can increase the satisfaction of the partner relationship of the franchisees.
Measuring exchange norms and its impact on satisfaction in a B2C context

This research investigates the relevance of exchange norms in a business-to-consumer context and studies the impact of both relational and discrete norms on customer satisfaction in services. As existing scales focus only on relational norms and are mostly limited to business-to-business contexts, Study 1 (n = 164) proposes measurement scales for seven exchanges norms adapted to a business-to-consumer context: Reciprocity, The Linking norms, Creation and restraint of power, Role integrity, Solidarity, Flexibility, and Effectuation of consent. Study 2 (n = 295) tests the influence on these norms on customer satisfaction. The article demonstrates that exchange norms as a whole positively affect customer satisfaction and, more specifically, that relational norms explain satisfaction better than discrete norms. The findings also show that, contrary to customer relationship proneness, relationship duration moderates the link between exchange norms and customer satisfaction.
Mossy cell dendritic structure quantified and compared with other hippocampal neurons labeled in rats in vivo

Mossy cells are likely to contribute to normal hippocampal function and to the pathogenesis of neurologic disorders that involve the hippocampus, including epilepsy. Mossy cells are the least well‐characterized excitatory neurons in the hippocampus. Their somatic and dendritic morphology has been described qualitatively but not quantitatively. In the present study rat mossy cells were labeled intracellularly with biocytin in vivo. Somatic and dendritic structure was reconstructed three‐dimensionally. For comparison, granule cells, CA3 pyramidal cells, and CA1 pyramidal cells were labeled and analyzed using the same approach. Among the four types of hippocampal neurons, granule cells had the smallest somata, fewest primary dendrites and dendritic branches, and shortest total dendritic length. CA1 pyramidal cells had the most dendritic branches and longest total dendritic length. Mossy cells and CA3 pyramidal cells both had large somata and similar total dendritic lengths. However, mossy cell dendrites branched less than CA3 pyramidal cells, especially close to the soma. These findings suggest that mossy cells have dendritic features that are not identical to any other type of hippocampal neuron. Therefore, electrotonic properties that depend on soma‐dendritic structure are likely to be distinct in mossy cells compared to other neurons.
Ribavirin effect on experimental Junin virus‐induced encephalitis

Junin virus, the etiological agent of Argentine hemorrhagic fever, produces in man a disease mainly characterized by hemorrhagic alterations, commonly accompanied by neurological symptoms, and leading to 10% mortality. Intracerebral inoculation in 10‐day‐old rats or intraperitoneal inoculation in 2‐day‐old rats leads to high mortality due to severe encephalitis. Here, the effect of Ribavirin on these experimental models was tested in order to evaluate the degree of protection achieved against neuropathological manifestations. In intracerebrally infected 10‐day‐old rats the drug was administered 2 hr before virus inoculation. Doses ranged from 30 to 90 mg/kg body weight. Protection reached 40% for the 60 and 90 mg doses. Intraperitoneally infected 2‐day‐old rats received the drug in five 30‐mg daily doses, starting the same day as virus inoculation. Survival was 73%. Viral replication within peritoneal macrophages dropped markedly, leading to much lower CNS viral titres. Together with results reported in primates, our findings support further studies on Ribavirin, with a view to eventual trials in humans.
Properties of Cement Mortar and Ultra-High Strength Concrete Incorporating Graphene Oxide Nanosheets

In this work, the effect of graphene oxide nanosheet (GONS) additives on the properties of cement mortar and ultra-high strength concrete (UHSC) is reported. The resulting GONS-cement composites were easy to prepare and exhibited excellent mechanical properties. However, their fluidity decreased with increasing GONS content. The UHSC specimens were prepared with various amounts of GONSs (0–0.03% by weight of cement). Results indicated that using 0.01% by weight of cement GONSs caused a 7.82% in compressive strength after 28 days of curing. Moreover, adding GONSs improved the flexural strength and deformation ability, with the increase in flexural strength more than that of compressive strength. Furthermore, field-emission scanning electron microscopy (FE-SEM) was used to observe the morphology of the hardened cement paste and UHSC samples. FE-SEM observations showed that the GONSs were well dispersed in the matrix and the bonding of the GONSs and the surrounding cement matrix was strong. Furthermore, FE-SEM observation indicated that the GONSs probably affected the shape of the cement hydration products. However, the growth space for hydrates also had an important effect on the morphology of hydrates. The true hydration mechanism of cement composites with GONSs needs further study.
Characterization of Progenitor-Cell-Specific Genes Identified by Subtractive Suppression Hybridization

We have utilized subtractive suppression hybridization (SSH) to identify differentially expressed genes present in either neuroepithelial (NEP) cells or glial restricted precursor (GRP) cells. Eighteen clones enriched in GRP cells and 28 in NEP cells were identified. Five of the GRP-specific clones (tenascin C, cystatin C, GABA transporter 3, extracellular matrix molecule 2 and H2–4) were characterized further, and their glial specificity was confirmed by RT-PCR, in situ hybridization and immunocytochemistry. H2–4 (an expressed sequence tag) was shown to be part of chondroitin sulfate proteoglycan 3. Overall, our results show that SSH can be used to identify lineage- and stage-specific markers and that extracellular matrix molecules likely play important roles in the migration and differentiation of GRPs.
Relationship based access control

Relationship Based Access Control (ReBAC) has emerged as a popular alternative to traditional access control models, such as Role Based Access Control (RBAC) and Attribute Based Access Control (ABAC). However, some of the model's aspects, such as its expression language and delegation abilities have not been studied in depth. Further-more, existing ReBAC models cater to single policy control, thus not taking into account cases were many access control policies might apply to a single access control object. We propose a ReBAC model, set theoretic ReBac (STReBAC), which bases its expression language on set theory. Our model is expressive and exible, catering to the above problems, and able to overcome access control challenges as discussed by popular ReBAC models without needing to alter its formal grammar. Additionally, we extend our model to handle situations where more than one policy applies to the same access control object. To achieve this we have combined our STReBAC model with PTaCL which is an evaluation framework for ABAC. We provide a solution which is compatible with many industrial standards, such as eXtensible Access Control Markup Language (XACML) and Ponder, and formalise techniques used by those very standards to extend our model without sacri�cing its original exibility. As part of our research, we implement a demonstrator that proves how our formal model can be applied to real life industrial problems, whether as a stand alone project or as part of a larger access control mechanism. To demonstrate the above, we implement our model in terms of Application Programming Interface (API)s that are widely used by today's industry. This shows that our STReBAC models can be translated into implementations which are exible and scalable.
