Tourism netnography: how travel bloggers influence destination image

ABSTRACT Travel bloggers are among digital influencers who share travels with their followers and impact their opinions. This study applies netnography to gain a better understanding of this influence on destination image formation. By choosing Okinawa as the destination, the online communications between two travel bloggers and their respective followers were studied. As most of their followers had no prior image towards Okinawa, the researchers could study how the promoted destination image was perceived by the followers. The findings revealed their practices as grabbing followers’ attention, self-discovery, followers’ involvement and sharing information. Followers were surprised and excited by this discovery and even some of them expressed intention to visit this Japanese archipelago. This study provides a protocol of using netnography for identifying destination image attributes through social media communications along with theoretical and managerial implications in tourism promotion and digital marketing.
Feasibility study of a hybrid grid‐tied photovoltaic‐wave system on the shores of Persian Gulf

The application of hybrid renewable energy systems (HRES) has been gaining ground in the recent years due to low‐carbon policies of nations and increasing energy demand. However, marine energy sources such as waves have remained untapped notwithstanding their significant potential particularly in Iran. Iran has significant wave and energy resources, which can be exploited to overcome the energy crisis in the country. In this regard, this research examines the feasibility of a 15 kW hybrid wave‐photovoltaic system in three ports of Iran namely Chabahar, Bushehr and Bandar Abbas on the shores of Persian Gulf and Oman Gulf using MATLAB/Simulink. Oscillating water column converters are deployed to harvest the wave energy. The findings indicated that the maximum energy production occurs in April for Chabahar and Bandar Abbas, and in July for Bushehr, while the minimum is in December for all the locations under study. The annual energy generation reaches 524, 506 and 520 kWh in Chabahar, Bandar Abbas and Bushehr, respectively. The levelized cost of electricity was estimated at 128 $/kWh for Bandar Abbas, 125 $/kWh for Bushehr and 124 $/kWh for Chabahar, indicating that Chabahar is the optimal location for the installation of the proposed system.
The relationship between Nrf2/Keap1 system and endoplasmic reticulum stress and inflammatory markers in peripheral blood mononuclear cells of type 2 diabetic subjects

Background: Oxidative stress, endoplasmic reticulum stress (ER stress), and inflammation are the main leading factors in the pathogenesis of type 2 diabetes. Nuclear factor erythroid 2-related factor 2/ Kelch-like ECH-associated protein 1 (Nrf2/Keap1) is the chief regulator of the antioxidant defense system that protects the cells against reactive oxygen species (ROS). ER stress and inflammatory pathways are involved in the suppression or the activation of the Nrf2/Keap1 system. In this study, we aimed to explore the possible relationships of the main factors contributing to oxidative stress, endoplasmic reticulum stress, and inflammation in peripheral blood mononuclear cells (PBMCs) of diabetic patients. Methods: Levels of biological parameters, oxidative stress markers as well as the gene transcription of Nrf2, Keap1, p22phox, Chop1, Grp78, IL-6, and TNF- were analyzed in the PBMCs of 32 type 2 diabetic and 31 non-diabetic subjects. The correlation analysis was performed for the markers of oxidative stress with selected ER stress-related genes and pro-inflammatory cytokines. Results: Fasting blood sugar (P<0.0001), HbA1c (P<0.0001), serum triglycerides (P = 0.024), insulin (P = 0.003), and HOMA-IR (P = 0.001) were significantly higher in diabetic patients compared with non-diabetic subjects. Levels of malondialdehyde (MDA) and carbonyl content were higher in the diabetes group. Conversely, total thiol content, and ferric reduction of plasma was higher in the healthy group. The mRNA levels of Nrf2 were negatively correlated with Keap1 and IL-6 gene expression. We observed a significant positive correlation between mRNA levels of Chop1, Grp78, and Nrf2 transcription levels. Conclusion: The data of the present study suggest that the impaired function of the Nrf2/Keap1 system is associated with pathological factors such as ER stress and inflammation.
Experimental and Numerical Analysis of an Expansion Flow in Chemical and Thermal Nonequilibrium

Results of a basic experiment on a high-expanding nozzle flow in hot gas conditions are presented and discussed. Gas flow temperatures and velocities at various locations at the inlet and the exit of a hypersonic nozzle designed for a hydrogen burning ramjet model were determined. The flow velocity was measured by laser two-focus velocimetry,detecting seeded TiO2-particles whose behavior in fast expanding flows was examined experimentally and numerically. CARS was applied to measure nitrogen single pulse spectra from which vibrational and rotational temperatures were determined. The flow at the exit of the nozzle shows a market thermal nonequilibrium because of the molecular exchange processes, which cannot keep pace with the expansion. The experimental results are compared to a numerical computation by a 2D FEM code solving the Navier-Stokes equations for a chemically reacting mixture of gases, using a reduced chemical kinetic scheme and modeling the vibrational energy and its relaxation by the Landau-Teller theory. Experimental and numerical results are in excellent agreement.
Immigrant Women’s Economic Outcomes in Europe: The Importance of Religion and Traditional Gender Roles

This article contributes to previous research on immigrant integration by examining how religiosity and gender roles in European countries influence immigrant women’s labor market outcomes. Moreover, we extend theoretical work on the importance of the receiving country’s norms and values by hypothesizing and testing whether receiving countries’ influence varies with immigrant women’s religiosity and gender-role attitudes. Using the European Social Survey data and multilevel regression models, we find that religious immigrant women participate less in the labor market and work fewer hours than nonreligious immigrant women. Immigrant women’s traditional gender-role attitudes partly explain the negative relationship between individual religiosity and labor market outcomes. While the receiving country’s religiosity is negatively related to immigrant women’s labor market outcomes, this negative relationship is significantly weaker for religious and gender-traditional immigrant women than for nonreligious and gender-egalitarian women. These findings suggest that the economic benefits of residing in countries that support female employment are limited to immigrant women who are ready and positioned to embrace gender-egalitarian norms and values.
From seep carbonates down to petroleum systems: An outcrop study from the southeastern France Basin

Despite the obvious link between hydrocarbon seepage at the surface and the activity of petroleum systems at depth, the majority of studies on seep carbonates concentrate on shallow aspects, whereas they are rarely oriented toward a source-to-sink perspective. Here, seep carbonates are conceptualized as a key element for analyzing petroleum systems at basin scale. Mapping of a 150-m-thick, 200-m-wide outcrop of the Lower Cretaceous slope wedge of the southeastern France Basin reveals two distribution patterns of seep carbonate concretions: (1) aligned in a continuous bed secant to the stratigraphy and (2) clustered in patches vertically stacked over 35 m. The δ13C signatures of the seep carbonates as light as −40‰ Peedee belemnite point toward a biogenic methane–dominated seepage. A set of turbidite channels pinching out right below the seep carbonates is seen as a potential gas trap, whereas biostratigraphic analysis indicates that the channels are coeval with a prominent black shale in the center of the basin. Any biogenic methane generated by the black shale could have used the channels as drains up to their pinch-out. The switch from a continuous seep carbonate level to stacked patches suggests initial widespread capillary leakage, followed by the opening of a preferential migration pathway. The distribution of seep carbonates thus appears dominated by breaching mechanisms of reservoir–cap-rock seals. This case study illustrates how seep carbonate mapping, in combination with the tectono-sedimentary context of each basin, may be a valuable tool for petroleum geologists.
How young people talk about their variations in sex characteristics: making the topic of intersex talkable via sex education

ABSTRACT Classrooms are important spaces for young people with variations in sex characteristics and their classmates. Sex education can promote agency and well-being by helping young people make sense of their embodiment and form rewarding social relationships and by changing societal understandings about variations in sex characteristics. Realising this potential however may hinge on how sex education makes intersex (un)talkable. We draw on interviews with 22 young people on how and why they try to make their variation in sex characteristics talkable with others. By focusing on how they talk to others and why they do not talk to others, this research highlights how participants ‘fear rejection’ but need to talk to others about their variation in the process of ‘dealing with it’. Participants also struggle with ‘secrecy versus privacy’ and how to ‘communicate strategically. ’ Findings acknowledge the emotional work required of people with variations in sex characteristics when making intersex talkable. The analysis points to the role of both talking and silence. We conclude by envisaging a norm-critical sex education that engages with the responsibilities of both talking and listening, shifting the burden away from individual young people with variations in sex characteristics and working towards more mutual social relationships.
Intense terahertz pulses inhibit Ras signaling and other cancer-associated signaling pathways in human skin tissue models

Terahertz (THz) radiation has shown unique advantages in biomedical applications for novel diagnostic technologies due to the high sensitivity to molecular structure and chemical concentration. However, emerging evidence shows that intense pulses of THz radiation can induce significant non-thermal biological effects that must be characterized. In human skin exposed to intense THz pulses, relatively large responses characterized by differential gene expression profiles are observed. These data are analyzed by signaling pathway perturbation analysis to predict phenotypic endpoints and dysregulatory effects on cancer-related processes. The activities of several important pathways that drive the initiation, development, and progression of many human cancers are predicted to be suppressed, and this effect is intensity-dependent. Some affected pathways are targets for current and emerging anti-cancer therapies. In particular, the activity of the Ras signaling and Calcium signaling pathways is predicted to be significantly inhibited. These results indicate the possibility of an additional therapeutic mechanism of intense THz pulses, due to the potential for targeted suppression of pro-mitotic activity in diseased tissue.
Dual-Polarization Absorptive/Transmissive Frequency-Selective Surface With Tunable Passband

A dual-polarization frequency-selective structure with a tunable passband and two absorptive bands is presented. Based on an equivalent circuit model (ECM), the working principle is investigated first. The values of components in the ECM are derived from the required performances and are mapped to the structure of an initial design, which is designed by cascading of an absorptive frequency-selective surface (FSS) realized with dipole-like elements and a lossless bandpass FSS achieved with square ring slot. For tuning the passband, varactors and biasing networks are added into the initial design. The adding of the varactors and biasing networks significantly affects the performance, and brings about the emergence of singular resonances. The approaches for mitigating the effects and the techniques for suppressing the singular resonances are proposed. Simulated results show that, between two absorptive bands, a passband is tuned from 3.33 to 5.13 GHz if the capacitances are decreased from 0.5 to 0.15 pF. A prototype is fabricated and measured. Measured results show that the passband is altered from 3.56 to 4.35 GHz as the reverse bias voltage of the used varactors is increased from 6 to 18 V.
Analysis of Community Response to Disasters through Twitter Social Media

Disasters that occur in a place can give a variety of reactions in the community. Social media users, the dissemination of Twitter with followers, makes it easy and fast to share emergency information like a disaster. Some disasters often occur in Indonesia, such as earthquakes, volcanic eruptions, weather anomaly, and flooding. To find out the public response to an accident, researchers conducted twitter data crawling on July 26, 2019, to July 29, 2019, using the keyword “gunung tangkuban parahu erupsi”, crawling data produced a dataset of 14,045 records. This study calculates the number of tweets before the disaster, to several days after the accident. The results of the survey indicate the response of the community to disasters relatively increased on the first day of the crash and decreased after two or three days after the disaster.
Factors Which Influence The Success of Google Classroom Based on Age

Many institutions use classroom virtual as support for student learning processes, including Google Classroom. The Samarinda Mulia University has been using Google Classroom since first released in 2014. The age characteristics of the respondents are considered to influence preferences towards the acceptance and use of a system. In this study, the test was conducted on the success of the Google Classroom to find out the factors that influence the success of the Google Classroom at Samarinda Mulia University based on the user’s age. Measure the success of Google Classroom using the Delone & McLean method. It has six evaluation variables that are information quality, system quality, service quality, user satisfaction, and net benefit. Data collected by questionnaires and in-depth interviews with almost two hundred Samarinda Mulia University students. The results show that there are differences in factors that influence the success of Google Classroom in users aged over 25 years and under 25 years.
Clinical Features and Quality of Life in Duchenne and Becker Muscular Dystrophy Patients from A Tertiary Center in Turkey

Introduction: Duchenne Muscular Dystrophy (DMD) and Becker Muscular dystrophy (BMD), are chronic and progressive and rare genetic disorders that cause systemic involvement such as progressive muscle deterioration, motor disability, cardiomyopathy, and respiratory problems, with an increased risk of cognitive decline and psychological problems They are a group of neuromuscular diseases in which psychological problems affect negatively on quality of life (Qol) not only patients but also caregivers. This study demonstrates the clinical features of patients with DMD/BMD and their caregivers and compares controls with respects to psychological and social aspects. Materials and Methods: A total of 20 patients (3 with BMD and 17 with DMD), aged between 8 and 18 years, and 20 age-matched healthy children were included in this descriptive and cross-sectional study. The patients were evaluated by the pediatric neurology, cardiology, and psychiatry departments at the study time. Their demographic and clinical features were recorded. The Wechsler Intelligence Scale for Children-Revised (WISC-R), Pediatric Quality of Life Inventory (PedsQL) and its parent form, and the Strengths and Difficulties Questionnaire (SDQ) were applied to all of the participants. Results: The QoL scores were lower in patients with moderate and severe DMD/ BMD and their caregivers. In patients with DMD and in both groups, emotional symptoms, peer problems and prosocial behavior scores were higher in the subsets of the SDQ. The PedsQL child-parent scores were lower in all of the subsets with statistical significance. Conclusions: DMD and BMD comprise a group of chronic diseases with multiple complications that are difficult to manage. A QoL equal or close to that of the healthy children should be targeted. Today, proposed or experimental treatments for this disease group are assessed based on their ability to enhance QoL. Inquiring into the QoL and counseling should become routine.
New Radical Cation Salts Based on BDH-TTP Donor: Two Stable Molecular Metals with a Magnetic [ReF6]2− Anion and a Semiconductor with a [ReO4]− Anion

Three radical cation salts of BDH-TTP with the paramagnetic [ReF6]2− and diamagnetic [ReO4]− anions have been synthesized: κ-(BDH-TTP)4ReF6 (1), κ-(BDH-TTP)4ReF6·4.8H2O (2) and pseudo-κ″-(BDH-TTP)3(ReO4)2 (3). The crystal and band structures, as well as the conducting properties of the salts, have been studied. The structures of the three salts are layered and characterized by alternating κ-(1, 2) and κ″-(3) type organic radical cation layers with inorganic anion sheets. Similar to other κ-salts, the conducting layers in the crystals of 1 and 2 are formed by BDH-TTP dimers. The partial population of positions of Re atoms and disorder in the anionic layers of 1–3 are their distinctive features. Compounds 1 and 2 show the metallic character of conductivity down to low temperatures, while 3 is a semiconductor. The ac susceptibility of crystals 1 was investigated in order to test the possible slow relaxation of magnetization associated with the [ReF6]2− anion.
An improved density peaks clustering algorithm based on CURE

As a new density-based clustering algorithm, clustering by fast search and find of Density Peaks (DP) algorithm regards each density peak as a potential clustering center when dealing with a single cluster with multiple density peaks, therefore it is difficult to determine the correct number of clusters in the data set. To solve this problem, a mixed density peak clustering algorithm namely C-DP was proposed. Firstly, the density peak points were considered as the initial clustering centers and the dataset was divided into sub-clusters. Then, learned from the Clustering Using Representatives algorithm (CURE), the scattered representative points were selected from the sub-clusters, the clusters of the representative point pairs with the smallest distance were merged, and a parameter contraction factor was introduced to control the shape of the clusters. The experimental results show that the C-DP algorithm has better clustering effect than the DP algorithm. The comparison of the F-measure Index shows that the C-DP algorithm improves the accuracy of clustering when datasets contain multiple density peaks in a single cluster.
Glycemic profile, inflammatory markers, biochemical and histopathological parameters of mice fed with fermented dairy beverage with clove essential oil

Previous studies have shown that the clove essential oil concentration of 200 mg/kg did not present toxicity and histopathological changes in the liver. Based on the evidence presented in this study, we decided to evaluate in vivo the ability of a previously developed fermented dairy beverage, tested only in vitro, in which the standard chemical preservative, potassium sorbate, was replaced by clove essential oil (2 μl/ml), to be a functional food. To this end, twenty-four male Swiss mice were divided into three groups and submitted insulin sensitivity (IST) and glucose tolerance (GTT) testing, evaluation of physiological and biochemical parameters, histopathological analysis and quantification of the expression of anti-inflammatory and pro-inflammatory cytokines in the liver, after administering daily of the fermented dairy beverage with or without clove essential oil by gavage during 30 days. The group that received the fermented dairy beverage with clove essential oil showed a lower glycemic level in GTT, a higher sensitivity to insulin and a higher glucose decay constant rate (Kitt), with relation to the other groups. In the evaluation of physiological parameters there were no signs of toxicity in the mice during the experimental period. The biochemical parameters, histopathological analysis and expression of anti-inflammatory (IL-10) and pro-inflammatory (IL1β, IL6 e TNFα) cytokines in the liver of the mice, was not significantly affected by the treatment. These results corroborated by bioinformatics analysis demonstrate that the fermented dairy beverage with clove essential oil it can function as a substitute for conventional chemical preservatives and reduce glycemic levels.
Joint security and performance improvement in multilevel shared caches

Ahmad Patooghy, Department of Computer Science, University of Central Arkansas, 201 Donaghey Ave., Conway, AR 72035, United States. Email: apatooghy@uca.edu Abstract Multilevel cache architectures are widely used in modern heterogeneous systems for performance improvement. However, satisfying the performance and security requirements at the same time is a challenge for such systems. A simple and efficient timing attack on the shared portions of multilevel hierarchical caches and its corresponding countermeasure is proposed here. The proposed attack prolongs the execution time of the victim threads by inducing intentional race conditions in shared memory spaces. Then, a thread‐mapping algorithm to detect such race conditions between a group of threads and resolve them as a countermeasure against the attack is proposed. The proposed countermeasure dynamically monitors races on cache blocks and distributes existing and new threads on processing cores to minimize cache contention. Upon detection of a high contention rate that might be either due to an attack or a natural race condition, two mechanisms, namely cache access‐rate reduction and thread migration, will be used by the countermeasure algorithm to resolve the race situation. Evaluations on SPECCPU 2006 benchmark suite show that the proposed algorithm not only protects the system against the introduced attack but also boosts the overall system performance by an average of 46.35% and 55.92% for the worst and average cases, respectively.
