The Contribution of Workplace Social Interactions to Employees Retention in Travel and Tourism Industry: A Theoretical Construct

As the other organizations, travel and tourism enterprises don’t aim at just recruiting high skilled, talented and productive workforce but also at retaining such employees despite this objective represents a challenge when we know that employees turnover rate is high in travel and tourism industry as found by many researches and studies conducted in several countries. The reason behind the high rate of employees turnover in travel and tourism industry is low remunerations, unsatisfactory work conditions, inflexible management system, long work hours, low job growth and advancement opportunities and so on , but the social interactions in work place among employees themselves and between employees and management, contribute to employees retention directly and through some mediator factors such as commitment, job satisfaction, low stress, and productivity that will be discussed in details in the current study.
Prevalence of white spot lesions during orthodontic treatment with fixed appliances.

OBJECTIVE To determine the prevalence of white spot lesions (WSLs) in orthodontic patients at 6 and 12 months into treatment using the visual examination method. MATERIALS AND METHODS Patients 6 and 12 months into treatment were examined for the presence of WSLs. The control group consisted of patients who were examined for WSLs immediately after bonding. Upon clinical evaluation, teeth were given a visual score based on the extent of demineralization. RESULTS The percentages of individuals having at least one WSL were 38%, 46%, and 11% for the 6-month, 12-month, and control groups, respectively. The 6-month (P = .021) and 12-month groups (P = .005) were significantly different from the control group but were not significantly different from each other (P = .50). Of subjects in the study who had at least one visible WSL, 76% were males and 24% were females (P = .009). CONCLUSIONS This clinical study showed a sharp increase in the number of WSLs during the first 6 months of treatment that continued to rise at a slower rate to 12 months. Clinicians should evaluate the oral hygiene status of patients during the initial months of treatment and, if necessary, should implement extra measures to prevent demineralization.
The benefits and obstacles of implementing ICTs strategies for development from a bottom-up approach

The compatibility between the implementation of information and communication technologies (ICTs) strategies and the bottom‐up approach in the developmental process is assessed. In order to put the theoretical arguments into practice, the existing benefits and obstacles of implementing such strategies in reality are presented. Deriving from the analysis of the bottom‐up approach is the identification of three key areas: basic needs, empowerment, and rural‐based development. These are later discussed in the context of ICTs strategies. The theoretical discussion is exemplified in short explanatory cases.
Transformational teaching and physical activity

Drawing from transformational leadership theory, this research examined adolescent perceptions of transformational teaching within school-based physical education. In Study 1, focus groups with 62 adolescents examined perceptions of physical education teachers’ behaviors. In Study 2, follow-up semi-structured interviews were conducted with 18 purposively sampled students. Findings revealed that behaviors within physical education settings can be understood within a conceptual framework that includes transformational teaching. In addition, students who perceived their teachers to utilize transformational behaviors described more adaptive responses. Issues concerning theory development and the application of transformational teaching to physical activity and health promotion settings are considered.
Mortality trends for cervical squamous and adenocarcinoma in the United States

In the United States, detection of squamous carcinoma in situ (CIS) by screening has led to reduced rates for invasive squamous carcinoma and lower mortality. Adenocarcinoma in situ (AIS) rates also have increased, but invasive cervical adenocarcinoma rates have not declined similarly. To make inferences about the effectiveness of screening, the authors assessed mortality trends for squamous and adenocarcinoma in relation to incidence of these tumors, incidence of their precursors and survival.
Towards Playful Office Culture: Final Report of the OASIS – Playful Spaces for Learning and Collaboration at Work (2014–2015) research project

In the project OASIS – Playful Spaces for Learning and Collaboration at Work (2014–2015), funded by the Finnish Work Environment Fund, the experience of playfulness and the incentives and thresholds of adult play at the workplace were examined. The research focused on a single academic work community, and it was closely connected to research enabled by OASIS, an informal social space for students and staff at the university and a living lab for research. The primary component of the research project comprised three playful experiments involving staff
Influential Characteristics of Physician/Pharmacist Collaborative Relationships

BACKGROUND A theoretical model of physician/pharmacist collaborative relationships, driven by 3 groups of relationship characteristics termed participant, context, and exchange, has been developed. There are no studies that have examined the types of characteristics which most influence development of collaborative relationships between physicians and pharmacists. OBJECTIVE To test the model and determine which drivers most influence physician/pharmacist collaboration. METHODS Data on the relationship drivers and collaborative practice were collected via a mailed survey of a random sample of 1000 primary care physicians in Iowa. Participant variables include demographics; context drivers refer to the practice environment and professional interactions between physicians and pharmacists. Exchange characteristics describe the nature of social exchange and were elicited using scores from 3 domains (relationship initiation, trustworthiness, role specification) of the Physician/Pharmacist Collaboration Instrument (PPCI). Five additional questions asked about the physician's collaborative practice with a pharmacist. Hierarchical linear regression analysis was performed with collaborative practice as the dependent variable and measures of participant, context, and exchange drivers as independent variables. RESULTS Three hundred forty usable surveys (34%) were returned. Almost 70% of the respondents were male and aged 45.8 ± 9.9 years (mean ± SD). The majority were family practice physicians (72.1%) in private practice (67.3%). Regression analyses produced an R2 = 0.804 (p < 0.001). Significant predictors in the model were internal medicine physicians, professional interaction with a pharmacist, and the 3 domains of exchange drivers from the PPCI (p < 0.05). CONCLUSIONS Although participant and context factors influenced physician/pharmacist collaborative relationships, exchange characteristics were the most influential relationship drivers. Role specification, trustworthiness, and relationship initiation were positively associated with physician/pharmacist collaborative practice. Recognition of these drivers may help pharmacists who are developing collaborative working relationships with physicians. But, studies are needed to delineate other factors that may influence physician/pharmacist relationships.
Culturally tailored education to promote lifestyle change in Mexican Americans with type 2 diabetes

Purpose: The purpose of this article is to report the results of a culturally tailored diabetes intervention for Mexican Americans on physical activity and to report the results of a focus group with intervention participants. Data sources: Seventeen Mexican American subjects with type 2 diabetes participated in the study. The study used a pretest/posttest control group design with 10 subjects in each group (N = 20). Outcome measures included the number of steps walked weekly, weight, and body mass index (BMI). Pedometers were used to measure the daily number of steps in the intervention group. A focus group provided data on participant satisfaction. Conclusions: Results suggest a positive effect of the intervention on physical activity level, weight, and sense of control over diabetes self‐management. Intervention participants had a statistically significant increase in the number of steps walked per day and a statistically significant mean weight loss of five pounds. Focus group results indicate that participants were satisfied with the culturally tailored intervention and that they and their families benefited from the intervention. Implications for practice: A culturally tailored diabetes self‐management program may result in improved outcomes for Mexican Americans with type 2 diabetes.
Developing a Business Model to Help SMEs Implement an Effective Supply Chain using Unified Modeling Language

Purpose: The purpose of this paper is to develop a business model using analytical tools to generate quantitative evidence of the benefits of implementing an effective supply chain to assure the success of the organization in a highly competitive environment, limiting the scope to Egyptian SMEs.Design/methodology/approach: The study primarily uses a mixed methods approach; including semi-structured interview that was conducted to Egyptian SMEs and the data collected we reanalyzed using the Unified Modeling Language technique which provides an effective object oriented modeling tool that could be an appropriate analysis tool in the SMEs that operate in Egypt. Findings: The analysis showed how the supply chain was defined by Egyptian SMEs; it also mapped the current performance of the supply chain in order to understand the process’s characteristics and capabilities. The result shows the obstacles and constrains facing the supply chain of the SME. Originality/value: Many SMEs in the Egyptian environment will be impacted as this research develops a model that suits them. The use of a Case Study approach with an object oriented tool, namely UML, makes this a thorough investigation that helps decision makers in Egyptian SMEs make better informed decisions.SMEs do not use the object oriented techniques in evaluating their problems, although it is very useful in analyzing the case study and modeling the current situation of the supply chain.
Solder Joint Reliability Assessment for a High Performance RF Ceramic Package

The prediction of long term solder joint reliability, (SJR), of microelectronic devices and packaging solutions continues to challenge the microelectronic packaging industry, particularly with the introduction of lead-free materials, the push for higher performance (frequency/speed/thermal) and lower unit cost. High performance packages are generally custom designed and therefore have minimal industry data on configuration specific reliability performance. In this application, the package substrate coefficient of thermal expansion, (CTE), was closely matched to the die resulting in a relatively large CTE mismatch between the package and organic PCB. In addition, the package RF and thermal performance requirements required this particular solution to be configured as a “cavity down” perimeter ball array with a large central ground pad to electrically couple the package to the PCB. Given the package's unique design requirements and CTE mismatch, even modest daily temperature swings of 20°C usually found in .
Profile-based event tracking

In this research, we focus on tracking topics that originate and evolve from a specific event. Intuitively, a few key elements of a target event, such as date, location, and persons involved, would be enough for making a decision on whether a test story is on-topic. Consequently, a profile-based event tracking method is proposed. We attempt to build an event profile from the given on-topic stories by robust information retrieval technologies. A feature selection metric and a recognized event clause are utilized to determine most (if not all) key semantic elements of the target event. Preliminary experiments on the TDT2 mandarin corpus show that this profile-based event tracking method is promising.
A learning procedure for speaker-dependent word recognition systems based on sequential processing of input tokens

This paper Presents a learning procedure for speaker-dependent word recognition systems which are based on the principle of dynamic time warping. The reference templates are created by averaging word tokens for each class. The averaging, procedure, which is based on a purely sequential processing of the tokens, contains additional weighting operations for word boundaries and scaling of the time axis. These operations improve the robustness of the learning procedure. The new learning procedure has been tested with different speech examples, some of which have been recorded in extremely noisy conditions with casual speakers. In all cases the learning procedure yields very reliable reference templates.
Our Treatment Approaches in Severe Maxillofacial Injuries Occurring After Failed Suicide Attempts Using Long-Barreled Guns

AbstractMaxillofacial traumas with long-barreled guns may sometimes cause catastrophic results by means of smashing in facial structures. In these patients, reconstruction strategies of both fragmented/lost soft and hard tissues still remain controversial. In their clinic, the authors treated 5 patients with severely injured face after failed suicide attempt between 2008 and 2013. In this study, the authors aimed to present their clinical experiences on these severely injured maxillofacial gunshot traumas and offer a treatment algorithm to gain a result as possible as satisfactory in terms of functionality and appearance.
Patiromer: The First Potassium Binder Approved in Over 50 Years

For over 50 years, there have been limited options for the management of hyperkalemia, especially among patients with chronic kidney disease (CKD), diabetic nephropathy, hypertension, and heart failure, who were receiving concomitant renin–angiotensin–aldosterone system (RAAS) inhibitor therapy. Hyperkalemia is a potential, life-threatening electrolyte abnormality that frequently challenges clinicians from maximizing the mortality benefit and organ-protective properties of RAAS inhibitors especially in CKD and heart failure populations. Patiromer is a novel nonabsorbed, cation-exchange polymer that binds and exchanges potassium for calcium, predominantly in the gastrointestinal tract. It has demonstrated potassium-lowering effects in normo- or hyperkalemic patients on concomitant RAAS inhibitors with heart failure, diabetic nephropathy, and CKD, in the PEARL-HF, AMETHYST-DN, and OPAL-HK studies, respectively. Across all studies, it appears to be generally effective and well tolerated, with adverse events predominantly gastrointestinal in nature. Additional investigational studies are needed to explore its use for an extended duration of treatment and in larger patient populations, as well as exploring drug–drug interactions. Overall, patiromer demonstrates a promising role in the chronic management of hyperkalemia that will allow optimization of RAAS inhibitor therapy, thus delaying progression of CKD and improving the mortality benefit in heart failure patients.
Novel Current Feedforward Average Current Mode Control Technique to Improve Output Dynamic Performance of DC-DC Converters

This paper proposes a novel current feedforward average current mode control (CFACMC) technique to improve output dynamic performance of DC-DC converters. In this new control scheme, besides its usual role as a feedback variable to a current controller, the sensed inductor current is fed forward, through a low-pass filter circuit, to sum with an output signal from a voltage controller to form the control signal. In the paper, the operating principle of CFACMC and its small signal model are described. From the small-signal model, the expression for selecting the gain of the low-pass filter to yield the improved output voltage response is derived. Both simulated and experimental results are provided to show that significant improvement in output dynamic response is achieved with CFACMC.
Maternal Deprivation and Early Weaning Modulate Experimental Allergic Encephalomyelitis in the Rat

The present experiment deals with the effect of maternal deprivation (MD) and early weaning (EW) on the development and course of experimental allergic encephalomyelitis (EAE) in Dark August (DA) rats. Five litters (five to nine pups per liter) were subjected to MD (4 h daily) from Day 1 until Day 28. EW rats were weaned on Day 15 (EW-15, five litters) or Day 21 (EW-21, four litters). Control rats and MD rats were weaned on Day 28. At the age of 8 weeks, rats were immunized with guinea pig spinal cord in complete Freund's adjuvant and clinical signs of EAE were recorded daily. On Day 18 after immunization, rats were bled and sacrificed. Brain and spinal cord were examined histologically for EAE lesions. Serum anti-rat myelin basic protein (MBP) antibodies were detected by ELISA. MD female rats exhibited suppression of neurological and histological signs of EAE in comparison with control rats. MD and control females showed elevated anti-MBP antibody level compared to MD and control males. EW-15 female rats demonstrated potentiation of neurological signs of EAE compared to control females. EW-21 females developed more severe clinical signs and histological lesions compared to control females. These results show that neonatal experiences, such as maternal deprivation and early weaning, influence the development of EAE in adult DA rats.
Long-term outcomes after repeat doses of antenatal corticosteroids.

BACKGROUND Previous trials have shown that repeat courses of antenatal corticosteroids improve some neonatal outcomes in preterm infants but reduce birth weight and increase the risk of intrauterine growth restriction. We report long-term follow-up results of children enrolled in a randomized trial comparing single and repeat courses of antenatal corticosteroids. METHODS Women at 23 through 31 weeks of gestation who remained pregnant 7 days after an initial course of corticosteroids were randomly assigned to weekly courses of betamethasone, consisting of 12 mg given intramuscularly and repeated once at 24 hours, or an identical-appearing placebo. We studied the children who were born after these treatments when they were between 2 and 3 years of corrected age. Prespecified outcomes included scores on the Bayley Scales of Infant Development, anthropometric measurements, and the presence of cerebral palsy. RESULTS A total of 556 infants were available for follow-up; 486 children (87.4%) underwent physical examination and 465 (83.6%) underwent Bayley testing at a mean (+/-SD) corrected age of 29.3+/-4.6 months. There were no significant differences in Bayley results or anthropometric measurements. Six children (2.9% of pregnancies) in the repeat-corticosteroid group had cerebral palsy as compared with one child (0.5% of pregnancies) in the placebo group (relative risk, 5.7; 95% confidence interval, 0.7 to 46.7; P=0.12). CONCLUSIONS Children who had been exposed to repeat as compared with single courses of antenatal corticosteroids did not differ significantly in physical or neurocognitive measures. Although the difference was not statistically significant, the higher rate of cerebral palsy among children who had been exposed to repeat doses of corticosteroids is of concern and warrants further study.

Calcium channel currents and their inhibition by (‐)‐baclofen in rat sensory neurones: modulation by guanine nucleotides.

1. The effect of intracellular application of the hydrolysis‐resistant GTP and GDP analogues, guanosine 5'‐O‐3‐thiotriphosphate (GTP‐gamma‐S), and guanosine 5'‐O‐2‐thiodiphosphate (GDP‐beta‐S) has been examined on voltage‐activated calcium‐channel currents and the ability of the gamma‐aminobutyric acid B agonist baclofen to inhibit them, in cultured rat dorsal root ganglion (d.r.g.) neurones. 2. Under control conditions, the calcium‐channel current, recorded using the whole‐cell patch technique with Ba2+ rather than Ca2+ as the permeant divalent cation, consists of an inactivating and a sustained current. In the presence of 500 microM‐GTP‐gamma‐S included in the patch pipette, the calcium‐channel current was activated more slowly and was largely non‐inactivating during the 100 ms depolarization voltage step. The effects of GTP‐gamma‐S were abolished by pre‐treatment of cells with pertussis toxin. 3. The calcium‐channel current recorded in the presence of 500 microM‐GDP‐beta‐S had a more marked transient component than the control calcium‐channel current. The proportion of transient calcium‐channel current in the presence of GDP‐beta‐S was not reduced in Na+‐free medium. 4. No statistically significant effects of GTP‐gamma‐S and GDP‐beta‐S were observed on the calcium‐activated potassium current IK(Ca), the transient outward potassium current activated in Ca2+‐free medium, or on the inwardly rectifying current (Ih) activated by hyperpolarization. 5. GTP‐gamma‐S increased the ability of baclofen to inhibit calcium‐channel currents, whereas this was decreased by GDP‐beta‐S and by pre‐treatment of cells with pertussis toxin. The half‐maximal effective dose (EC50) for baclofen was 2 microM in the presence of GTP‐gamma‐S, 15 microM for control and 50 microM in the presence of GDP‐beta‐S. Comparable results were obtained using a single concentration of the adenosine agonist 2‐chloroadenosine (2‐CA, 0.05 microM) to inhibit calcium‐channel currents; its effect was significantly increased by GTP‐gamma‐S and reduced by GDP‐beta‐S. 6. The ability of baclofen to inhibit calcium‐channel currents was not affected by 1 microM‐forskolin or 50 microM‐intracellular cyclic AMP. 7. It is concluded that calcium channels in d.r. g.s are associated with a nucleotide binding protein, and that this mediates the effect of baclofen and 2‐CA on calcium‐channel currents. The ability of GTP‐gamma‐S to inhibit the transient component of calcium‐channel currents in the absence of agonist may represent a means of differentially regulating calcium‐channel activity.
Prognostic Implications of Cyclin B1, p34cdc2, p27Kip1 and p53 Expression in Gastric Cancer

Purpose Cell cycle progression is regulated by interactions of specific cyclins and cyclin dependent kinases (CDKs) at the G1-S and G2-M checkpoints and cell cycle deregulation plays a major role in carcinogenesis of human cancers. Patients and Methods To investigate the role of cell cycle regulators in the pathogenesis and progression of human gastric cancers, 23 cases of gastric carcinomas were examined for the expression of cyclin B1, p34cdc2, p27Kip1 and p53 by immunohistochemical methods, and gene expression was correlated with various clinicopathologic findings. Results Out of 23 cases studied, cyclin B1 was diffusely expressed in 20 cases (87.0%), p34cdc2 in 14 cases (60.9%) and p53 in 12 cases (52.2%), whereas in normal gastric tissues, cyclin B1 and p34cdc2 were weakly expressed and p53 was not expressed. In contrast, p27Kip1 was expressed in only 8.7% of gastric carcinomas compared with 78.3% of normal gastric tissues. There was correlation between the expression of cyclin B1 and expression of p34cdc2 (p = 0.002), between the expression of cyclin B1 and loss of p27Kip1 (p = 0.025), and between the expression of p34cdc2 and loss of p27Kip1 (p = 0.065). In addition, expression of cyclin B1 was correlated with regional lymph node metastasis (p = 0.032). Conclusion Our results indicate that cyclin B1 and p34cdc2 are involved in the genesis or progression of gastric cancers. Furthermore, overexpression of cyclin B1 may play an important role in lymph node metastatic potential of gastric cancer. Thus, abnormal expression of cyclin B1 and CDKs, overexpression of p53 and loss of p27Kip1 expression may play important roles in human gastric carcinogenesis.
