The Role of Strategic Communication in Hospitality Industry ¡°The Case of Antalya¡±

The success of organizations depends on various factors such as effective organizational structure, well-defined roles and responsibilities and the structure and process of communication within the organization. As one of the determinants of success in tourism establishments as well as all types of other organizations, communication is the fundamental condition which enables coordination of organizational functioning. In tourism management literature, however, this topic is observed not to be adequately dealt with. Therefore, this article aims to contribute to tourism management literature. Another purpose of the article, on the other hand, is to analyze the communication process between managers and employees of tourism establishments on a strategic dimension. Data was gathered through questionnaires implemented at the 5-star hotels located in Antalya, since Antalya is one of the most important destinations in Turkey, attracting the highest numbers of tourists. Data was subjected to explanatory factor analysis in order to identify the dimensional structure of communication. Then, regression analysis was conducted in order to identify relationships between the variables. Results of the study suggested that there was a positive link between strategic communication dimension and operational effectiveness, as well as increased overall effectiveness of the organization and better internal operational qualities of separate departments.
Correlation of Pathologic Features With CpG Island Methylator Phenotype (CIMP) by Quantitative DNA Methylation Analysis in Colorectal Carcinoma

Extensive gene promoter methylation in colorectal carcinoma has been termed the CpG island methylator phenotype (CIMP). Previous studies on CIMP used primarily methylation-specific polymerase chain reaction (PCR), which, unfortunately, may detect low levels of methylation that has little or no biological significance. Utilizing quantitative real-time PCR (MethyLight), we measured DNA methylation in a panel of 5 CIMP-specific gene promoters (CACNA1G, CDKN2A (p16), CRABP1, MLH1, and NEUROG1) in 459 colorectal carcinomas obtained from 2 large prospective cohort studies. CIMP was defined as tumors that showed methylation in ≥4/5 promoters. CIMP was significantly associated with the presence of mucinous or signet ring cell morphology, marked Crohn's-like lymphoid reaction, tumor infiltrating lymphocytes, marked peritumoral lymphocytic reaction, tumor necrosis, tumor cell sheeting, and poor differentiation. All these features have previously been associated with microsatellite instability (MSI). Therefore, we divided the 459 colorectal carcinomas into 6 subtypes, namely, MSI-high (MSI-H)/CIMP, MSI-H/non-CIMP, MSI-low (MSI-L)/CIMP, MSI-L/non-CIMP, microsatellite stable/CIMP, and micro satellite sstable/non-CIMP. Compared with MSI-H/non-CIMP, MSI-H/CIMP was associated with marked tumor infiltrating lymphocytes, tumor necrosis, sheeting, and poor differentiation (all P≤0.05). Compared with MSI-L/non-CIMP, MSI-L/CIMP was associated with tumors that had <50% signet ring cell component, marked tumor infiltrating lymphocytes, and poor differentiation (all P<0.05). In conclusion, several pathologic features that have previously been shown to be associated with MSI are also significantly associated with CIMP. Both MSI and CIMP appear to play a role in the pathogenesis of specific morphologic patterns of colorectal carcinoma.
Analysis of the performance of an Ultrasonic Local Positioning System based on the emission of Kasami codes

This work presents the performance analysis of an Ultrasonic Local Positioning System (ULPS). The system is composed of four beacons, forming a square structure in the ceiling of a rectangular room, that emit orthogonal Kasami codes BPSK modulated with a carrier frequency of 50 kHz. These emissions are detected by the receiver by pulse compression, giving the system high precision and robustness to noise. A complete model of the system has been built to conduct this study, considering effects such as the ultrasonic transducers response, signal attenuation in air, multipath propagation, reflection coefficient of walls and floor and receiver response. This model helps to identify critical zones where the self-induced noise generated in the cross-correlations masks the main peaks of the auto-correlations, making it difficult to obtain reliable Time-of-Flights from which the receiver's position is determined. Also, the dependence of these critical zones with different parameters integrated in the model is investigated.
Problem Based Learning: An instructional model and its constructivist framework

It is said that there’s nothing so practical as good theory. It may also be said that there’s nothing so theoretically interesting as good practice 1 . This is particularly true of efforts to relate constructivism as a theory of learning to the practice of instruction. Our goal in this paper is to provide a clear link between the theoretical principles of constructivism, the practice of instructional design, and the practice of teaching. We will begin with a basic characterization of constructivism identifying what we believe to be the central principles in learning and understanding. We will then identify and elaborate on eight instructional principles for the design of a constructivist learning environment. Finally, we will examine what we consider to be one of the best exemplars of a constructivist learning environment -- Problem Based Learning as described by Barrows (1985, 1986, 1992).
Clinical decisions presented to patients in hospital encounters: a cross-sectional study using a novel taxonomy

Objective To identify and classify all clinical decisions that emerged in a sample of patient–physician encounters and compare different categories of decisions across clinical settings and personal characteristics. Design Cross-sectional descriptive evaluation of hospital encounters videotaped in 2007–2008 using a novel taxonomy to identify and classify clinically relevant decisions (both actions and judgements). Participants and setting 372 patients and 58 physicians from 17 clinical specialties in ward round (WR), emergency room (ER) and outpatient (OP) encounters in a Norwegian university hospital. Results The 372 encounters contained 4976 clinically relevant decisions. The average number of decisions per encounter was 13.4 (min–max 2–40, SD 6.8). The overall distribution of the 10 topical categories in all encounters was: defining problem: 30%, evaluating test result: 17%, drug related: 13%, gathering additional information: 10%, contact related: 10%, advice and precaution: 8%, therapeutic procedure related: 5%, deferment: 4%, legal and insurance related: 2% and treatment goal: 1%. Across three temporal categories, the distribution of decisions was 71% here-and-now, 16% preformed and 13% conditional. On average, there were 15.7 decisions per encounter in internal medicine specialties, 7.1 in ear–nose–throat encounters and 11.0–13.6 in the remaining specialties. WR encounters contained significantly more drug-related decisions than OP encounters (P=0.031) and preformed decisions than ER and OP encounters (P<0.001). ER encounters contained significantly more gathering additional information decisions than OP and WR encounters (P<0.001) and fewer problem defining decisions than WR encounters (P=0.028). There was no significant difference in the average number of decisions related to the physician’s and patient’s age or gender. Conclusions Patient–physician encounters contain a larger number of clinically relevant decisions than described in previous studies. Comprehensive descriptions of how decisions, both as judgements and actions, are communicated in medical encounters may serve as a first step in assessing clinical practice with respect to efficiency and quality on a provider or system level.
Benthic oxygen exchange in a live coralline algal bed and an adjacent sandy habitat: an eddy covariance study

Coralline algal (maerl) beds are widespread, slow-growing, structurally complex perennial habitats that support high biodiversity, yet are significantly understudied compared to seagrass beds or kelp forests. We present the first eddy covariance (EC) study on a live maerl bed, assessing the community benthic gross primary productivity (GPP), respiration (R), and net ecosys- tem metabolism (NEM) derived from diel EC time series collected during 5 seasonal measurement campaigns in temperate Loch Sween, Scotland. Measurements were also carried out at an adja- cent (~20 m distant) permeable sandy habitat. The O2 exchange rate was highly dynamic, driven by light availability and the ambient tidally-driven flow velocity. Linear relationships between the EC O2 fluxes and available light indicate that the benthic phototrophic communities were light - limited. Compensation irradiance (Ec) varied seasonally and was typically ~1.8-fold lower at the maerl bed compared to the sand. Substantial GPP was evident at both sites; however, the maerl bed and the sand habitat were net heterotrophic during each sampling campaign. Additional inputs of ~4 and ~7 mol m −2 yr −1 of carbon at the maerl bed and sand site, respectively, were required to sustain the benthic O2 demand. Thus, the 2 benthic habitats efficiently entrap organic carbon and are sinks of organic material in the coastal zone. Parallel deployment of 0.1 m 2 benthic chambers during nighttime revealed O2 uptake rates that varied by up to ~8-fold between repli- cate chambers (from −0.4 to −3.0 mmol O2 m −2 h −1 ; n = 4). However, despite extensive O2 flux vari- ability on meter horizontal scales, mean rates of O2 uptake as resolved in parallel by chambers and EC were typically within 20% of one another.

Construction of a Genetic Linkage Map Based on Amplified Fragment Length Polymorphism Markers and Development of Sequence-Tagged Site Markers for Marker-Assisted Selection of the Sporeless Trait in the Oyster Mushroom (Pleurotus eryngii)

ABSTRACT A large number of spores from fruiting bodies can lead to allergic reactions and other problems during the cultivation of edible mushrooms, including Pleurotus eryngii (DC.) Quél. A cultivar harboring a sporulation-deficient (sporeless) mutation would be useful for preventing these problems, but traditional breeding requires extensive time and labor. In this study, using a sporeless P. eryngii strain, we constructed a genetic linkage map to introduce a molecular breeding program like marker-assisted selection. Based on the segregation of 294 amplified fragment length polymorphism markers, two mating type factors, and the sporeless trait, the linkage map consisted of 11 linkage groups with a total length of 837.2 centimorgans (cM). The gene region responsible for the sporeless trait was located in linkage group IX with 32 amplified fragment length polymorphism markers and the B mating type factor. We also identified eight markers closely linked (within 1.2 cM) to the sporeless locus using bulked-segregant analysis-based amplified fragment length polymorphism. One such amplified fragment length polymorphism marker was converted into two sequence-tagged site markers, SD488-I and SD488-II. Using 14 wild isolates, sequence-tagged site analysis indicated the potential usefulness of the combination of two sequence-tagged site markers in cross-breeding of the sporeless strain. It also suggested that a map constructed for P. eryngii has adequate accuracy for marker-assisted selection.
The mapping of texture on VR polygonal models

The paper addresses the problem of choosing automatically, and without user intervention, the best possible 2D image that should be used to map as a texture on polygons of a geometric model of complex scenes made of several objects. The geometric models and the texture data are obtained separately: the models are built from range data while the texture information is obtained from 2D color images of the scene. The system does not make any assumption on the way the texture data has been acquired. Texture selection results are presented for an indoor scene.
Noninvasive measurement of dissolved oxygen in shake flasks.

Shake flasks are ubiquitous in cell culture and fermentation. However, conventional devices for measuring oxygen concentrations are impractical in these systems. Thus, there is no definitive information on the oxygen supply of growing cells. Here we report the noninvasive, nonintrusive monitoring of dissolved oxygen (DO) in shake flasks using a low-cost optical sensor. The oxygen-sensitive element is a thin, luminescent patch affixed to the inside bottom of the flask. The sensitivity and accuracy of this device is maximal up to 60% DO, within the range that is critical to cell culture applications. By measuring actual oxygen levels every 1 or 5 min throughout the course of yeast and E. coli fermentations, we found that a modest increase in shaker speed and a decrease in culture volume slowed the onset of oxygen limitation and reduced its duration. This is the first time that in situ oxygen limitation is reported in shake flasks. The same data is unattainable with a Clark type electrode because the presence of the intrusive probe itself changes the actual conditions. Available fiber optic oxygen sensors require cumbersome external connections and recalibration when autoclaved.
International Consensus on Standardization of Data Collection for Complications Associated With Esophagectomy: Esophagectomy Complications Consensus Group (ECCG).

INTRODUCTION Perioperative complications influence long- and short-term outcomes after esophagectomy. The absence of a standardized system for defining and recording complications and quality measures after esophageal resection has meant that there is wide variation in evaluating their impact on these outcomes. METHODS The Esophageal Complications Consensus Group comprised 21 high-volume esophageal surgeons from 14 countries, supported by all the major thoracic and upper gastrointestinal professional societies. Delphi surveys and group meetings were used to achieve a consensus on standardized methods for defining complications and quality measures that could be collected in institutional databases and national audits. RESULTS A standardized list of complications was created to provide a template for recording individual complications associated with esophagectomy. Where possible, these were linked to preexisting international definitions. A Delphi survey facilitated production of specific definitions for anastomotic leak, conduit necrosis, chyle leak, and recurrent nerve palsy. An additional Delphi survey documented consensus regarding critical quality parameters recommended for routine inclusion in databases. These quality parameters were documentation on mortality, comorbidities, completeness of data collection, blood transfusion, grading of complication severity, changes in level of care, discharge location, and readmission rates. CONCLUSIONS The proposed system for defining and recording perioperative complications associated with esophagectomy provides an infrastructure to standardize international data collection and facilitate future comparative studies and quality improvement projects.
Effects of psychosocial variables in the similarity and interdependence of physical activity levels among adolescent best friend dyads

ABSTRACT Given that physical activity (PA) tends to decrease with age during adolescence, addressing factors that affect change is important. This study examined the similarity and interdependence of PA as influenced by psychosocial factors among adolescent best friend dyads. A total of 660 adolescents, representing 330 best friend dyads, completed questionnaires with regard to PA, sitting time, perceived exercise benefits and barriers, physical self-perception and social support for PA. Dyads were also identified as reciprocal and non-reciprocal best friends; reciprocal means that both considered each other best friends and non-reciprocal were those in which only one considered the other a best friend. Data were analysed using a hierarchical linear model framework. Results indicated significant similarities between reciprocal best friend dyads for PA and sitting time, and for sitting time in non-reciprocal best friends (P values <.01). Psychosocial variables were associated with PA in reciprocal best friend dyads and with sitting time in reciprocal and non-reciprocal best friend dyads. Best friend gender, regular sports practice of the person, perceived exercise barriers of the best friend and best friend social support were the best predictors for PA.
The MS Co-O perative Research (MS-CORE) group: an alternate approach to fostering multicenter studies

Sir The recent article by Kappos et a7. ,~ discussing the European initiative to form a network for clinical trials, advocates several important and timely principles and mechanisms to foster clinical research in multiple sclerosis (MS). The authors discuss several important dilemmas facing the MS research community: inadequate nonindustry support; inadequate access to data by investigators ; and inadequate comparability between trials. To address these inadequacies, the authors plan to establish a network of MS centers to facilitate identification of
Aspects of cognitive understanding of the environment by vision-based semantic mapping

The role of mobile robots in our daily lives has been increasing rapidly during the last decades. Essential elements of such systems are sophisticated perceptual and cognitive skills, extraction and storage of knowledge, and methods for action planning. The main contributions presented in this thesis are vision-based methods for object detection and mapping, a cognitive system for knowledge representation and decision making based on semantic maps, and the integration in an autonomous mobile robot. By advancing the perceptual and cognitive skills of mobile robots, the proposed methods support navigation in real urban environments. Simulations and experiments have been conducted to verify the presented cognitive abilities.
Coordinated motion control of multiple robotic devices for welding and redundancy coordination through constrained optimization in Cartesian space

The authors consider the problem of coordinating multiple motion devices for welding purposes. They focus on the problem of controlling a positioning table and a seven-axis manipulator, given the parametric definition of a trajectory on a weld piece. The problem is complex as there are more than nine axes involved and a number of permutations are possible which achieve the same motions of the weld torch. The system is redundant and the robot has singular configurations. As a result, manual programming of the robot system is rather complex. The authors illustrate an approach to redundancy control and coordination of a multiple-robotic-device arc welding system that does not require manual teaching of the intermediate trajectory points. The system requires only the start and end points of the trajectory for setting up and calibration. The redundancy coordination scheme is based on constrained optimization of the maneuverability of the manipulator in Cartesian space. To bypass accuracy issues related to joint rate control, inverse kinematics is directly used in the kinematic control of the manipulator. <<ETX>>
Predictive Control of Heat Supply Process Based on BP Predictive Model and Gold Section Algorithm

According to the characteristics of heat supply and the demands of energy-saving control, predictive control based on BP model and gold section method is proposed. BP model is trained with real data from heat supply system, and then solving control rate by gold section algorithm. This control strategy uses rolling optimization and feedback correction, it effectively overcomes the problems of time-delay, uncertain, nonlinear in heat supply process.The simulation results show the effectiveness of this method in control system, it also has a good track performance.
SPEAKER VERIFICATION USING I-VECTOR REPRESENTATION

I-vectors have proved to be the most effective features for text-independent speaker verification in recent researches. In this article a new scheme is proposed to utilize i-vectors in text-prompted speaker verification in a simple while effective manner. In order to examine this scheme empirically, a telephony dataset of Persian month names is introduced. Experiments show that the proposed scheme reduces the EER by 31% compared to the state-of-the-art State-GMM-MAP method. Furthermore it is shown that using HMM instead of GMM for universal background modeling leads to 15% reduction in EER.
The Speech Act Theory in English and Arabic

This paper is mainly concerned with proving that it is not Wittgenstein, the German philosopher, who actually seeded the main gist of the Speech Act Theory; there are others who preceded him (and all those who followed him, the first of whom is Austin) in doing so: Arab scholars. Accordingly, this work starts by reviewing the most basic ideas of the original theory proposed by Austin and developed by Searle. The basic ideas presented by the Arabic theory are presented in the second section, and then a contrast between the two is made.
Vascular Wall Maturation and Prolonged Angiogenic Effect by Endothelial-Specific Platelet-Derived Growth Factor Expression

Background: The implementation of angiogenic gene therapy at clinics is hindered by the transience of the therapeutic effect. Recruiting vascular wall smooth muscle cells, a process termed ‘maturation’, can stabilize newly formed vessels. Objective: To induce angiogenesis followed by vessel maturation in a murine ischemic limb model by endothelial cell-specific promoter regulated expression of vascular endothelial growth factor (VEGF) and platelet-derived growth factor-BB (PDGF-BB). Methods: We constructed adenoviral vectors containing angiogenic factors VEGF and PDGF-B regulated by a modified preproendothelin-1 (PPE-1-3x) promoter and investigated their angiogenic effect in a murine ischemic limb model. Results: VEGF gene therapy increased perfusion and the vessel density in the limb shortly after expression with PPE-1-3x promoter or cytomegalovirus (CMV) promoter vectors, but only PPE-1-3xVEGF treatment exhibited a sustained effect. Expression of PDGF-B by PPE-1-3x promoter resulted in morphological maturation of the vasculature and further increased the perfusion, while nonspecific expression of PDGF-B with CMV promoter had no therapeutic effect. Regulation of dual therapy with VEGF and PDGF-B by PPE-1-3x promoter resulted in an early-onset, sustained angiogenic effect accompanied by vessel maturation. Conclusions: Systemic gene therapy with the angiogenic factors VEGF and PDGF-B under angiogenic- endothelial cell-specific regulation was effective in inducing functionally and morphologically mature vasculature.
Super optimal rates for nonparametric density estimation via projection estimators

In this paper, we study the problem of the nonparametric estimation of the marginal density f of a class of continuous time processes. To this aim, we use a projection estimator and deal with the integrated mean square risk. Under Castellana and Leadbetter’s condition (Stoch. Proc. Appl. 21 (1986) 179), we show that our estimator reaches a parametric rate of convergence and coincides with the projection of the local time estimator. Discussions about the optimality of this condition are provided. We also deal with sampling schemes and the corresponding discretized processes. r 2005 Elsevier B.V. All rights reserved.
