Exploring the Immersion and Telepresence in Gamified Virtual Tourism Experience toward Tourist’s Behaviour

Research and application of virtual tourism has been rapidly developing in the industrial era 4.0. However, research about perspective of tourist behavior in virtual tourism is still lacking, especially in Indonesia. This research method used is explanatory research with a survey that implemented on tourist to gamification-based virtual tourism presented of Virtual Arena in Jawa Timur Park 3. The results of the analysis shows that the ability to create virtual experiences in the form of immersion is not necessarily followed by the ability to provide telepresence experiences for a virtual destination, therefore it produces different effects on tourist behavior such as attitude and revisit intention. Keywords—virtual tourism; gamificatio; immersion; telepresence; attitude; revisit intention
Efficacy of Cancer Immunotherapy: An Umbrella Review of Meta-Analyses of Randomized Controlled Trials

We conducted a systematic review for evidence of the clinical efficacy of cancer immunotherapies. We searched PubMed from inception to 14 February 2018 for meta-analyses of randomized controlled trials (RCTs) of cancer immunotherapies. Re-analyses were performed to estimate the summary effect size under random-effects, the 95% confidence interval (CI), heterogeneity, and the 95% prediction interval, and we determined the strength of the evidence. We examined publication bias and excess significance bias. 63 articles corresponding to 247 meta-analyses were eligible. Nine meta-analyses were classified to have convincing evidence, and 75 were classified as suggestive evidence. The clinical benefit of immunotherapy was supported by convincing evidence in the following settings: anti-PD-1/PD-L1 monoclonal antibody (mAb) therapy for treating advanced melanoma and non-small cell lung cancer (NSCLC), the combination of rituximab and chemotherapy for treating chronic lymphocytic leukemia and B-cell non-Hodgkin’s lymphoma, adoptive cell immunotherapy for NSCLC, and the combination of interferon α and chemotherapy for metastatic melanoma. A further meta-analysis of 16 RCTs showed that anti-PD-1/PD-L1 mAb therapy had a benefit in patients with solid tumors (overall survival; hazard ratio = 0.73, 95% CI: 0.68–0.79; p < 0.001), supported by convincing evidence. In the future, rigorous approaches are needed when interpreting meta-analyses to gain better insight into the true efficacy of cancer immunotherapy.
Persuasive Silence

In the market where inattentive buyers can fail to notice some feasible choices, the key role of marketing is to make buyers aware of products. However, the e¤ective marketing strategy is often subtle since marketing tactics can make buyers cautious. This paper provides a framework to analyze an e¤ective marketing strategy to persuade an inattentive buyer in an adverse selection environment. We investigate how an attention-grabbing marketing can back reand when it can be e¤ective.
ASSESSMENT OF ANXIETY SYMPTOMS IN ADULTS WITH ACNE VULGARIS

Background: Acne vulgaris has been associated with psychiatric and psychological problems and it is one of the leading causes of anxiety in adolescents and adults. Aim of this study: To assess the link between anxiety symptoms and patients with acne vulgaris in relation to the severity of the disease, its localization and socio-demographic data. Material and Methods: A transverse cross-sectional study was undertaken from January 2010 to September 2011. In it participated 360 patients with acne vulgaris and 289 healthy individuals, of both sexes, 18-35 years old. For the assessment of the anxiety symptoms DASS questionnaire were used. Results: Patients with acne had higher level of anxiety symptoms than did controls (P<0.05). The symptoms of anxiety in patient group were not significant in relation to the severity of the disease, its localization, gender, employment and education (P>0.05). The symptoms of anxiety were significantly related to the marital status (single status) and patients age (26-35 years old) (P<0.05). Conclusion: There is a strong association of anxiety with acne vulgaris, but symptoms of anxiety are not affected by the the clinical features of the disease.
Master ’ s Degree in Biomedical Engineering Feasibility Study of Average Threshold Crossing ( ATC ) Technique Application in Muscle Synergies Analysis

In the last few decades, the concept of “Muscle Synergies” has been investigated as a way to better grasp the strategies used by the Central Nervous System (CNS) to simplify the control of body’s muscles. Behind this theory, in the fulfillment of a particular motor task that involves the recruitment of a certain number of muscles, the brain acts managing few temporal activation patterns that correspond to few muscles modules. In this way, the associated computational burden on the CNS is reduced to the control of a few modules instead of a higher number of individual muscles. The aim of this study is to verify the feasibility of the Average Threshold Crossing (ATC) approach in examining muscle synergies. More specifically, the ATC is an event-driven transmission technique that consists of an event generated each time the Surface Electromyography (sEMG) signal exceeds a fixed threshold. The number of threshold crossing events related to a particular time window is correlated to the force produced by the muscle. ATC offers a drastic reduction of data and the simple hardware schemes, its wireless suitability and low power consumption, are all advantages which have piqued the interest of its application in muscle synergies analysis. To extract muscle synergies, the most common procedure described in literature was followed. Starting from the sEMG envelopes matrix, it is based on the Non-negative Matrix Factorization (NNMF) decomposition algorithm. Since the ATC depends on two parameters (threshold level and time window), in order to find the best combination that extracts ATC signals which are very similar to the sEMG envelopes, it has been considered to use a simulated approach based on sEMG signals. The results of the simulations have shown that the ATC technique, with the particular combination of time window = 50 ms and threshold level 2.8, is able to extract a signal which is very similar (R2≥ 85%) to the sEMG traditional envelope only when it is computed averaging across multiple realizations. The latter is valid when the sEMG signal is characterized by a Signal to Noise Ratio (SNR) at least of 10dB and for activations with temporal support at least of 150 ms. As a final step, using real sEMG signals collected from the lower limbs of 8 healthy subjects during gait, it has been possible to compare the outputs of the extraction, i.e. synergies weights W and temporal coefficients H, between the two methods: traditional and ATC. Specifically, the results have been extracted from the average sEMG envelope (both traditional and ATC) within a subgroup, which
The Technological Intensity of Government Demand and Private R&D Activities∗

This paper investigates the role of the inter-industry composition of government demand in innovation. We develop an endogenous growth model with quality-improving innovations that incorporates industries with heterogeneous innovation sizes. The model posits that a shift in the composition of government purchases to the benefit of high-tech industries encourages additional private R&D. We empirically test the implications of the model using detailed administrative data on federal procurement in U.S. states. In support of the model, we find that the technological content of public procurement can effectively alter private R&D activities. Instrumental variable results suggest that the estimated effect is indeed causal. JEL code: E62, H57, O31, O38
PATTERN OF INJURIES TO MOTORCYCLISTS IN FATAL ROAD TRAFFIC ACCIDENTS

Study of pattern of injuries in road traffic accidents helps us to know the measures to be taken at different levels to reduce suffering to human beings. Injuries to the limbs (96%) and head (95%) occurred in most of the cases followed by chest and abdomen. In head region, scalp contusion, fissured fracture of the skull and subdural hemorrhage were more commonly seen than other injuries. Lungs and liver suffered maximum among visceral organs. Contusions were more commonly seen in scalp and brain unlike that of abrasions present on chest, abdomen and limbs. Femur fracture (n=16) was more than other long bones. Head injury was the primary cause of death (69%) in most of the cases. Fatal motorcycle accidents are associated with a wide spectrum of injuries involving multiple anatomical regions.
Exergy and Energy Analysis of Diesel Engine Fuelled with Diesel and Diesel – Corn Oil Blends

Article history: Received 24 August 2019 Received in revised form 14 September 2019 Accepted 7 October 2019 Available online 10 November 2019 Exergy and energy analysis of diesel engine fuelled with pure diesel and diesel – corn oil blends are the focus of this study. The analyses were carried out by using the results of experiments of fuels for different engine speeds. The obtained results revealed that the input exergy and energy of diesel – corn oil blends were lower than of that of conventional diesel at the same conditions. The exergy destruction is the major fraction of fuel exergy lost. Moreover, the exergy destruction increase with an increased engine speed for both conventional and diesel – corn oil blends. The destructed exergy of the test engine operating on diesel – corn oil blends was higher than that of conventional. It has been determined that exergertic efficiency and thermal decreases as the diesel – corn oil blends content in fuel increase so the highest values of exergertic efficiency and thermal efficiency were obtained for the diesel fuel. It was also observed that the exergertic efficiency value is lower than that of the thermal efficiency under the same conditions. Results also showed the diesel – corn oil blends can be used as a substitute for diesel fuel.
Inherent Tradeoffs in Learning Fair Representation

With the prevalence of machine learning in high-stakes applications, especially the ones regulated by anti-discrimination laws or societal norms, it is crucial to ensure that the predictive models do not propagate any existing bias or discrimination. Due to the ability of deep neural nets to learn rich representations, recent advances in algorithmic fairness have focused on learning fair representations with adversarial techniques to reduce bias in data while preserving utility simultaneously. In this paper, through the lens of information theory, we provide the first result that quantitatively characterizes the tradeoff between demographic parity and the joint utility across different population groups. Specifically, when the base rates differ between groups, we show that any method aiming to learn fair representations admits an information-theoretic lower bound on the joint error across these groups. To complement our negative results, we also prove that if the optimal decision functions across different groups are close, then learning fair representations leads to an alternative notion of fairness, known as the accuracy parity, which states that the error rates are close between groups. Finally, our theoretical findings are also confirmed empirically on real-world datasets.
Firm Dynamics and Random Search over the Business Cycle

I build a tractable random search model with firm dynamics, on-the-job search, and aggregate shocks. Multi-worker firms make recruitment decisions, choose whether to enter or exit the market, and design wage contracts. Tractability is obtained by showing that, under a set of assumptions on the recruitment technology, the decisions of workers and firms can be expressed in terms of the firms’ current productivity. I introduce a numerical solution method to accommodate aggregate shocks in this environment and show that the model can replicate salient features of both firm-level data on productivity and employment and aggregate time series describing the business cycle. I use this framework to quantify the drivers of worker reallocation over the recent business cycle in Britain.
OPTH_A_205352 913..920

James A Davison Sarah Makari Richard Potvin 1Wolfe Eye Clinic, Marshalltown, IA, USA; 2Science in Vision, Akron, NY, USA Purpose: To assess the value of intraoperative aberrometry (IA) in determining toric intraocular lens (IOL) power in eyes with no previous ocular surgery. Patients and methods: This was a retrospective data review at one US clinical site of eyes that underwent uncomplicated cataract surgery with toric IOL implantation where standard preoperative and IA measurements were available. Calculated IOL sphere and cylinder powers and orientation were compared based on the measurement method and the postoperative refraction, using both actual and simulated (back-calculated) results. Comparisons were between the surgeon’s preoperative calculations, IA measurements, the actual IOL implanted and results from the Barrett toric calculator. Results: There was no significant difference (p>0.7) in the number of eyes expected to have, or having, a spherical equivalent refraction within 0.50D of the target between Actual (92%), IA (93%) or Preoperative calculation results (86%). The percentage of eyes with expected residual refractive astigmatism ≤0.50D was significantly higher for the IA vs Preoperative calculations (75% vs 53%, p<0.01). There was no significant difference in expected results between the Actual, IA and Barrett toric calculations (p>0.65). Conclusion: Modern IOL calculations for sphere produced results comparable to those achieved with IA. The value of IA in determining IOL cylinder power and orientation was more evident when comparing expected results between IA and a preoperative method based on measured total corneal astigmatism than when comparing to expected results from the Barrett toric calculator.
Influence and Total Antioxidant Capacity of Non-enzymatic Antioxidants on the Quality and Integrity of Extended and Cryopreserved Semen of Murrah Buffalo (Bubalus bubalis)

Reactive oxygen species (ROS) production is a normal physiological process; however, an imbalance between ROS generation, scavenging activity, and uncontrolled production of ROS that exceeds the antioxidant capacity of the seminal plasma will lead to oxidative stress and can damage the sperm membrane integrity, DNA, acrosome, metabolic activity, and fertilizing potential of the sperm (Bansal and Bilaspuri 2010, Tariq et al. 2015). In the stages of freezing and thawing, the endogenous defense system of the buffalo semen is not enough to counter oxidative stress due to low concentration of naturally occurring antioxidants in buffalo semen (Ansari et al. 2012). Sperm viability is also decreased by 50% whereas fertilizing capacity is affected after cryopreservation (Lessard et al. 2000). However, the spermatozoa are provided with protection from oxidative damages with the

It can be better managed by mental preparation and by appropriate change in lifestyle like regular physical exercise and with assurance to the urban girl.
Awareness and Practice of Breast Self Examination among Women in South India

Breast cancer is the most common malignancy affecting women, with more than one million cases occurring worldwide annually. In India, it is the second commonest cancer among females. Though it can be detected early by self and clinical breast examination or mammography, in our country only 15% patients present in the localized stage; in 75% regional lymph nodes are already involved while 10% have distant spread at the time of reporting (Rajvir Bhalwar, 2009).
Study on the Catalytic Pyrolysis Mechanism of Lignite by Using Extracts as Model Compounds

Understanding the catalytic pyrolysis mechanism of lignite is of great significance for obtaining a high yield of the target products or designing high-efficiency catalysts, which are generally derived by using simple model compounds, while the ordinary model compounds cannot represent the real atmosphere of lignite pyrolysis owing to the simple structures and single reactions. Based on the coal two-phase model, the extractable compounds are the important compositions of coal, which can reflect the partial characteristics of raw coal while obtaining a high extraction yield. Hence, a better understanding of the interaction between the coal structure and catalyst can be inferred by using a mobile phase in coal as model compounds instead of conventional simple compounds. In this work, tetrahydrofuran extracts of lignite were chosen as model compounds to study the catalytic pyrolysis mechanism with separate addition of Fe(NO3)3 and FeCl3 by using a thermogravimetric combined with mass spectrometry. It was found that about 77.88% of the extracts were vaporized before 700 °C, and the residual yield was 22.12%. With the separate addition of 5 wt % of Fe(NO3)3 and FeCl3, the conversion of the extracts increased to 84.38% and 89.66%. Meanwhile, the final temperature decreased to 650 and 550 °C, respectively. The addition of Fe(NO3)3 and FeCl3 promoted the breakage of aliphatic chains at approximately 150 °C, leading to the generation of CH4 and H2 in the temperature range 100–200 °C, which were nearly invisible for that without catalyst. The addition of iron-based catalysts allowed more CO2 formation at approximately 200 °C since they enabled efficient promotion of the cleavage of carboxyl functionals at lower temperatures. The enlarged peak of H2O and CH4 at approximately 500 °C means that iron-based catalysts are significant for the cleavage of methoxy groups in the catalytic respect. Aromatic side chains facilitated cracking at approximately 500 °C, leading to more light aliphatics and aromatics generation in this temperature range.
www.econstor.eu Identity and the Dynamics of Preferences

Some recent economic contributions have studied individual identity in terms of explicit choices and social categories to which a person belongs to. According to Social Psychology, identity is also the result of a process inuenced by self-regulation mechanisms. We model endogenous identity-dependent preferences as the dynamic result of two mechanisms: environmental pressure and the persistent e¤ect of past socialization in the adaptation to new environments We apply this model to environments where the agent must tradeo¤ conicting utility functions, such as material and non-material payo¤s, or self-interest and other-regarding preferences. The model shows that heterogeneity in individual preferences, besides being the result of socialization, cultural transmission and environmental incentives, critically hinges on the feed-back of behaviour on preferences1.

Board Structure, Ownership Structure, and Performance of Thai Listed Companies

This study investigates whether board gender diversity influences corporate social responsibility (CSR) reporting in Jordan, where there are no gender board balance regulatory requirements. Data was examined from all non-financial Jordanian listed companies for the period of 2006 to 2015. This longitudinal data results in balanced panel data of 800 observations. A content analysis method was used to obtain the reporting index of CSR disclosure in the annual reports. Ordinary least square regression showed that the presence of female directors on a board has a significantly positive effect on the level of CSR reporting. The presence of female directors on the board appears to play a significant role in enhancing compliance with corporate governance best practices. These results provide motivations for companies to consider gender balance on boards. Further, these results reinforce the decision making of regulators in countries where policies have been adopted to increase female representation on corporate boards. In countries where no such regulation exists the inclusion of gender balance practices within boards of directors may increase the level of CSR reporting practices. This study can be considered as one of the few empirical studies that have evaluated the impact of board gender diversity on the level of CSR reporting in a context where there are no gender balance strategies or policies.
Effect of pentoxifylline on correction of anaemia due to chronic diseases in systemic lupus erythematosus

This study aimed to evaluate the effect of Pentoxif ylline on correction of anaemia of chronic diseases in systemic lupus erythematosus. Seventy patients with systemic lupus erythematosus (SLE) and anaemia aged 28.9 ± 5.6 were studied in 2013 in a clinical trial. Sampling metho d was random permutation blocks in two groups of co ntrol and intervention patients. Intervention group received pentoxifylline; after 4 months, haemoglobin, iron a nd TNF α profiles of the two groups were compared. Data were analysed using T-test. The results showed that the haemoglobin increased by 0.2mg/dl in the interventi on group and 0.26mg/dl in the control group, which was statistically insignificant. Changes in ferritin, serum iron and serum iron/TIBC were respectively -3. 6±58.4 µg/dl, 1.6±28.8 µg/dl and 0.02±1.0 µg/dl in the Pentoxifylline group and 2.0±59. 1µg/dl, 0.6±28.5 µg/dl and 0.01±0.1 µg/dl in the placebo group. TNF α changes were -1.5±8.8pg/dl in the Pentoxifylline g roup and 0.2±4.0pg/dl in the placebo group, which was not statistically significant. The refore, receiving Pentoxifylline in anaemic patient s with SLE have no effect on haemoglobin levels and iron profiles o f these patients.
