Benchmarking holiday experience: the case of senior tourists

The purpose of this paper is to determine and benchmark the senior tourists’ preferences by considering the importance attached by them and their perception with respect to internal tourism attributes (i.e. package tour characteristics) and external tourism attributes (i.e. destination features). ,The present study makes use of importance-performance analysis and employs paired sample t-test for this purpose. ,The senior tourists evaluated the package tour attributes to be more important and better than destination characteristics. They also perceived that the service providers have to pay immediate attention to improve the quality of restaurants and meals and hotels. ,Data are collected only from inbound senior tourists in Poland. In future, research may be conducted with a more representative sample. ,The senior tourists want to explore the local cuisine and then have food choices from their culture as well. “Tour escort” is one of the most essential characteristic of a package tour and it could serve as a factor of differentiation. Hence, the tourist service providers have to pay attention to these factors. ,The paper takes into account the internal tour attributes and destination attributes to evaluate senior tourists’ holiday experience.
INTERSTELLAR ABUNDANCES FROM ABSORPTION-LINE OBSERVATIONS WITH THE HUBBLE SPACE TELESCOPE

▪ Abstract The Goddard High-Resolution Spectrograph (GHRS) aboard the Hubble Space Telescope (HST) has yielded precision abundance results for a range of interstellar environments, including gas in the local medium, in the warm neutral medium, in cold diffuse clouds, and in distant halo clouds. Through GHRS studies, investigators have determined the abundances of elements such as C, N, O, Mg, Si, S, and Fe in individual interstellar clouds. These studies have provided new information about the composition of interstellar dust grains, the origin of the Galactic high-velocity cloud system, and the processes that transport gas between the disk and the halo. Precision measurements of the interstellar D to H ratio and of the abundances of r- and s-process elements have also provided fiducial reference values for cosmological and stellar evolutionary observations and theoretical models.
Improving Customer Reactions to Electronic Brokered Ultimatums: The Benefits of Prior Experience and Explanations

Because of the growth of online discount travel intermediaries (e.g., Priceline), researchers have become interested in how customers react to electronic brokered ultimatum bargaining contexts. This paper investigates how characteristics of the customer and characteristics of the bargaining context might ameliorate customers' (a) perceptions of justice; (b) willingness to recommend the intermediary to others; and (c) willingness to repatronize the intermediary. We found that customer familiarity generally improved customer reactions to the electronic intermediary. We found a moderating effect for intermediary explanations in the form of an excuse, as explanations improved customer reactions when offers were rejected, but worsened reactions when offers were accepted.
The binary mixing behavior of phospholipids in a bilayer : A molecular dynamics study

Molecular dynamics simulations have been used to study the properties of mixed dioleoylphosphatidylcholine/ dioleoylphospatidylethanolamine bilayers as a function of phosphatidylcholine (PC)/phosphatidylethanolamine (PE) head-roup composition. The equilibrium properties of mixed PC/PE bilayers were found to be nonlinear in the composition. The properties studied show saturation behavior at a PC/PE ratio of 1:3. The effect of adding small amounts of PE to PC bilayers is a strong reduction of the area of the bilayer. The effect of adding small amounts of PC to PE bilayers is an increased hydration of the PC headgroups compared to PC hydration in pure PC bilayers. Nearest-neighbor analysis did not indicate lateral ordering of the lipids for any mixture. The observed trends are discussed in terms of the size of, and the interactions between, PC and PE headgroups.
Chronic Renal Failure andAluminum Toxicity on Dentin in Albino Rats

The objective of the present study was to examine the manifestations of uremia and aluminum loading on dentin structure and to determine whether characteristic changes, analogous to those seen in bone, occurs in the dentin of teeth in patients suffering from chronic renal failure (CRF) and may therefore be useful to the clinician in diagnosing renal osteodystrophy (ROD). Thirty albino rats with average 200g were randomized into 3 groups; control, study group I and II. CRF was induced in the study groups II10(2):73-82).

Effect of Mushroom Beta Glucan (MBG) on Immune and Haemocyte Response in Pacific White Shrimp (Litopenaeus vannamei)

The total haemocyte count (THC), differential haemocyte count (DHC), respiratory bursts, and phenoloxidase (PO) activity were determined in the Pacific white shrimp Litopenaeus vannamei which administrated by feeding with diets containing mushroom beta glucan (MBG) at 0.05% and 0.1%. Results showed that shrimp fed a diet containing 0.05% MGB had significantly increased THC and semi-granular cells ratio at 28 days. Intracellular superoxide anion (O2-) production were significantly increased at 14 days which shrimp fed a diet containing 0.05% MBG and PO activity were significantly increased at 14 days which shrimp fed a diet containing 0.1% MGB but equal with control at 28 days. In previously study, semi-granular cells were found as the primary immune activator with their high levels of granules, enzymes and proteins. In this study, the effectively enhance immune responses and compare to high induced semi-granular cells in Pacific white shrimps concluded that MBG is an effective and powerful immunostimulants for shrimp. For application in aquaculture, MBG administration through dietary administration is also a convenient and useful practical technique in the future.
Search forηandη′invisible decays inJ/ψ→ϕηandϕη′

Using a sample of $(225.3\pm 2.8)\times 10^{6}$ $J/\psi$ decays collected with the BESIII detector at BEPCII, searches for invisible decays of $\eta$ and $\eta^\prime$ in $J/\psi\to\phi\eta$ and $\phi\eta^\prime$ are performed. Decays of $\phi \to K^{+}K^{-}$ are used to tag the $\eta$ and $\eta^\prime$ decays. No signals above background are found for the invisible decays, and upper limits at the 90% confidence level are determined to be $2.58\times10^{-4}$ for the ratio $\frac{\mathcal{B}(\eta\to\rm{invisible})}{\mathcal{B}(\eta\to\gamma\gamma)}$ and $2.39\times10^{-2}$ for $\frac{\mathcal{B}(\eta^\prime\to\rm{invisible})}{\mathcal{B}(\eta^\prime \to\gamma\gamma)}$.
Real Time Hardware System for Synchronizing IoT Device State using the MQTT Protocol

with the growing number of IoT devices, there is an increasing need for the ability to synchronize state and data across multiple IoT devices. As many IoT devices will be operating in constrained environments with unstable network connections, understanding the tradeoffs of various protocols is critical. The primary objective of this paper is to design and implement an embedded system to connect to a M2M broker, use the cloud server to communicate with other embedded systems, and be configurable from a cloud-based web service. In this paper we explore previous research on machine to machine (M2M) protocols such as AMQP and MQTT, and demonstrate an MQTT based system for synchronizing IoT device state across multiple client nodes. The main goal of the system is for state changes to be registered and distributed throughout the system in under 1 second; and initial registration of a new node should occur in under 30 seconds.
Detection of Mouse Mammary Tumor Virus MMTV Antigens in Different Pathological Tissue forms of Iraqi Women- Breast Samples using Immunohistochemistry Staining

Mouse mammary tumor virus (MMTV) is a β-retrovirus that cosider as the most common cause of breast cancer in mice. However its role in human breast cancer is very controversial yet. Iraq having increasing rate of breast cancer and high prevalence in comparison to other cancer types among Iraqi people, Iraqi women suffering from a very aggressive fast-growing breast cancer, revealing causes and predisposing factors for such cases may help in saving lives of such women. Accordingly, the current study worked on detection of MMTV antigens (envelope glycoprotein 52(gp52) and capsid protein 27 (p27)) within Iraqi women breast cancer tissue samples and other comparative groups, cases were chosen from area highly endemic with house mouse. Immunohistochemical staining was performed using 97 samples of Formalin-Fixed Paraffin –Embedded (FFPE) Breast Tissues using specific antibodies targeting gp52 & p27 antigens. Although, results showed non significant differences for percentage of MMTV antigens positive results within Breast Cancer samples 7.31% (3 of 41), Fibroadenoma samples 5.26% (1 of 19), Mastitis samples 5.55% (1 of 18) and Ductectesia samples 5.26% (1 of 5.26). Despite of this low positive percentage, the presence of MMTV in human breast tissues is significant because MMTV is an animal virus so, the results may support the possibility of viral transmission from mice to human by direct or indirect contact and act as a co-factor with other oncogenes to induce breast cancer.

New operations for interval-valued Pythagorean fuzzy set

Interval-valued Pythagorean fuzzy set (IVPFS), originally proposed by Peng and Yang, is a novel tool to deal with vagueness and incertitude. As a generalized set, IVPFS has close relationship with interval-valued intuitionistic fuzzy set (IVIFS). IVPFS can be reduced to IVIFS satisfying the condition $mu^++nu^+ leq 1$. However, the related operations of IVPFS do not take different conditions into consideration. In this paper, we initiate some new interval-valued Pythagorean fuzzy operators ($diamondsuit, Box, spadesuit, clubsuit, maltese, rightarrow, $ $) and discuss their properties in relation with some existing operators $(cup, cap, oplus, otimes)$ in detail. It will promote the development of interval-valued Pythagorean fuzzy operators. Later, we propose an algorithm to deal with multi-attribute decision making (MADM) problem based on proposed $spadesuit$ operator. Finally, the effectiveness and feasibility of approach is demonstrated by mine emergency decision making example.
Examination of parental involvement in Greek female athletes.

The purpose of this study was to examine perceived and desired parental involvement in female sports in Greece. The parental involvement in sport questionnaire was administrated to 383 female former and current athletes (mean age 20.33 years, competitive experience 7.10 years) from different sports (rhythmic gymnastics, artistic gymnastics, swimming, basketball, volleyball, track and field). The questionnaire assessed athletes' perception about their parental involvement (directive behavior, praise and understanding, active involvement, pressure) and their desired parental involvement. The results showed that athletes in rhythmic, artistic gymnastics and swimming scored higher in praise and understanding, rhythmic and artistic gymnastics athletes perceived higher active involvement than desired and rhythmic gymnastics athletes perceived higher directive behavior than desired. Athletes in specializing phase desired more parental praise and understanding. Finally, pressure was predicted from all parental involvement variables. As parental involvement differs between sports, the results are discussed in order to minimize the negative influence of parental involvement in each sport.
Role of Non-HDL Cholesterol and LDL C /HDL c Ratio to Assess cardio vascular risk in Type- II Diabetic Patients

Diabetes mellitus is the commonest metabolic abnormality in the world. It has been estimated that more than 33 million people in India are affected by diabetes. Patients with type- II diabetes have 2 - 4 times higher risk of experiencing cardiovascular disease than adults without diabetes. Diabetic dyslipidemia consists of elevated LDL C, Triglycerides and decreased levels of HDL C. Recent data suggests that measurement of Non–HDL Cholesterol level (Total Cholesterol minus HDL C) could be more representative of all atherogenicapolipoprotein (Apo) B containing lipoproteins. Although Apo-B can be assessed directly, measurement of Non-HDL C can be considered as a surrogate marker for Apo B in routine clinical practice. Also LDL C to HDL C ratio > 4:1 is predisposing to heart disease whereas a ratio < 4:1 is protective. To evaluate the Lipid profile including Non-HDL C levels and LDL C/ HDL-C ratio in type II Diabetic Patients as markers of diabetic dyslipidemia. Age and sex matched 100 cases and 100 controls were included in the study . All the samples were analysed forFasting plasma glucose, Triglycerides, Total cholesterol,LDL cand HDL c. whereas Non-HDL cholesterol and LDL c/ HDL c ratio were calculated. There was a significant increase in Non-HDL cholesterol (p<0.001) and LDLC/ HDL-C ratio (P<0.05) in diabetic patients compared to age and sex matched controls. Type II diabetis mellitus leads to dyslipidemia causing increased levels of Non-HDL Cholesterol along with LDL C/HDL C ratio which indicates increased impending cardiovascular risk.
THE ASIAN GROWTH MIRACLE: FACTOR ACCUMULATION, THE DEMOGRAPHIC TRANSITION AND R&D-DRIVEN GROWTH

The spectacular growth rates in the Asian miracle economies (AMEs) are often attributed to factor accumulation whilst ignoring the forces that have been responsible for it. Using data for six AMEs over the period from 1953 to 2009, this paper extends the conventional growth accounting exercise by allowing for the population growth drag and endogeneity of capital deepening, savings, labor force participation and schooling. It is shown that growth has been predominantly a result of the demographic transition and productivity growth, where the latter has been driven by R&D, knowledge spillovers through imports and R&D absorptive capacity.
A Displacement and Amplitude Score Employing an Optical Flow Technique

A field verification measure for precipitation forecasts is presented that combines distance and amplitude errors. It is based on an optical flow algorithm that defines a vector field that deforms, or morphs, one image to match another. When the forecast field is morphed to match the observation field, then for any point in the observation field, the magnitude of the displacement vector gives the distance to the corresponding forecast object (if any), while the difference between the observation and the morphed forecast is the amplitude error. Similarly, morphing the observation field onto the forecast field gives displacement and amplitude errors for forecast features. If observed and forecast features are separated by more than a prescribed maximum search distance, they are not matched to each other, but they are considered to be two separate amplitude errors: a missed event and a false alarm. The displacement and amplitude error components are combined to produce a displacement and amplitude score (DAS). The two components are weighted according to the principle that a displacement error equal to the maximum search distance is equivalent to the amplitude error that would be obtained by a forecast and an observed feature that are too far apart to be matched. The new score, DAS, is applied to the idealized and observed test cases of the Spatial Verification Methods Intercomparison Project (ICP) and is found to accurately measure displacement errors and quantify combined displacement and amplitude errors reasonably well, although with some limitations due to the inability of the image matcher to perfectly match complex fields.
Gender, Competitiveness, and Study Choices in High School: Evidence from Switzerland

Willingness to compete has been found to predict individual and gender differences in educational choices and labor market outcomes. We provide further evidence for this relationship by linking Swiss students' Baccalaureate school (high school) specialization choices to an experimental measure of willingness to compete. Boys are more likely to specialize in math in Baccalaureate school. In line with previous findings, competitive students are more likely to choose a math specialization. Boys are more likely to opt for competition than girls and this gender difference in competitiveness could partially explain why girls are less likely to choose a math-intensive specialization.
Effect of Anabolic Steroids on the Cardiac and Skeletal Muscles of Adult Male Rats

Abuse of anabolic androgenic steroids (AASs) by athletes has been increased rapidly in many countries to improve their physical fitness and appearance. The abuses of AASs have been associated with impacts on different systems of the body. The present study was conducted to evaluate the histological changes that occurred in skeletal and cardiac muscles during nandrolone (one of AASs) treatment histologically and immunohistochmically. Forty adult male albino rats were divided into four groups. Group 1; control group, group 2; was treated with nandrolone 5 mg/kg intramuscularly weekly, group 3 was treated with nandrolone10 mg/kg intramuscularly weekly and group 4; was treated with nandrolone 20 mg/kg intramuscularly weekly. All groups were treated for 8 weeks. The specimens from the cardiac and skeletal muscles were processed for histological study using light and electron microscopes and immunohistochemical stain for detection of activated caspase-3 as an indicator for apoptotic changes. The skeletal and cardiac muscles appeared hypertrophied after nandrolone treatment. Lesions ranged from mild to severe muscular changes were also detected depending on the dose. The changes were in the form of variations of fibers size and splitting of some fibers in skeletal muscle as well as myofiber lysis, cellular infiltration, vacuolation, swelling and mitochondrial damage in both skeletal and cardiac muscles. The nuclei appeared hyperchromatic with peripherally clumped chromatin. Expression of caspase-3 was significantly increased in skeletal and cardiac tissues treated with higher doses of nandrolone. It is concluded that nandrolone injection in male albino rats induced hypertrophy and degenerative changes in the skeletal and cardiac muscles which may lead to loss of their functions.
Environmental Pesticides and Heavy Metals — Role in Breast Cancer

The intent of this chapter is to provide an overview to the current thoughts and ideals regarding the involvement of pesticides and heavy metals in the progress of breast cancer. The history of pesticides encompasses a few millennia, but our understanding of the pesticide action and the health consequences has only begun to develop in the last 30-40 years. Interestingly, many of these pesticides have estrogen-like activity and may be involved in the development of breast cancer. A new category of estrogen-like compounds has been identified and studied in the last 30 years, the ‘metalloestrogens’. Heavy metals, such as cadmium, which have estrogen like activity will be discussed. Finally, we will attempt to pull together the actions of pesticides and metalloestrogens as a possible synergistic mechanism by which these toxins may work to promote breast cancer development.
B IOMIMETIC POLYSACCHARIDE / BIOACTIVE GLASS NANOPARTICLES MULTILAYER MEMBRANES FOR GUIDED TISSUE REGENERATION

Nowadays, guided tissue regeneration (GTR) research is centred in the development of composite bioabsorbable membranes with enhanced bioactivity and with processing controlled at the nanoscale. Inspired by this new focus of GTR research and also by nacre structure, layered freestanding membranes were produced using the Layer-by-Layer (LbL) deposition technique, combining chitosan (CHI), hyaluronic acid (HA) and bioactive glass nanoparticles (BGNPs). It is expected that the combination of these materials processed by this particular technique will result in nanostructured membranes with enhanced mechanical performance as well as improved bioactivity. Moreover, the effect of the modification of HA with catechol groups (HAD) on the adhesive properties of the membranes was also analysed. The results showed that it was possible to produce biomimetic membranes with different surface properties, improved adhesive strength and the ability to induce the formation of apatite, necessary for the formation of new bone. It was also possible to control the BGNPs content of the membranes by use of HAD instead of unmodified HA and changing the number of BGNPs’ deposition steps. Moreover, it was shown that membranes with different concentrations of BGNPs possess different mechanical performance, swelling properties and degradation behaviour, which indicates the possibility to tune the membranes’ properties by controlling the deposition of BGNPs onto the membranes.
The Effect of an Introduced Summer Steelhead Hatchery Stock on the Productivity of a Wild Winter Steelhead Population

We investigated the effect of a hatchery program for summer steelhead Oncorhynchus mykiss on the productivity of a wild winter steelhead population in the Clackamas River, Oregon. We used a suite of Ricker and Beverton-Holt stock-recruitment models that incorporated species interaction variables to demonstrate that when high numbers of hatchery summer steelhead adults were present the production of wild winter steelhead smolts and adults was significantly decreased. We found that large releases of hatchery smolts also contributed to the decrease in wild adult productivity. Averaged over the results of our models, a 50% decline in the productivity parameter (the number of recruits per spawner at low densities) and a 22% decline in the maximum number of recruits produced in the basin were observed when high numbers of hatchery fish were present. We concluded that over the duration of the hatchery program, the number of hatchery steelhead in the upper Clackamas River basin regularly caused the total number of steelhead to exceed carrying capacity, triggering density-dependent mechanisms that impacted the wild population. The number of smolts and adults in the wild winter steelhead population declined until critically low levels were reached in the 1990s. Hatchery fish were removed from the system in 2000, and early results indicate that the declining trends have reversed.
Using dynamic vegetation models to simulate plant range shifts

Dynamic vegetation models (DVMs) follow a process-based approach to simulate plant population demography, and have been used to address questions about disturbances, plant succession, community composition, and provisioning of ecosystem services under climate change scenarios. Despite their potential, they have seldom been used for studying species range dynamics explicitly. In this perspective paper, we make the case that DVMs should be used to this end and can improve our understanding of the factors that influence species range expansions and contractions. We review the benefits of using process-based, dynamic models, emphasizing how DVMs can be applied specifically to questions about species range dynamics. Subsequently, we provide a critical evaluation of some of the limitations and trade-offs associated with DVMs, and we use those to guide our discussions about future model development. This includes a discussion on which processes are lacking, specifically a mechanistic representation of dispersal, inclusion of the seedling stage, trait variability, and a dynamic representation of reproduction. We also discuss upscaling techniques that offer promising solutions for being able to run these models efficiently over large spatial extents. Our aim is to provide directions for future research efforts and to illustrate the value of the DVM approach.
