The association of risk factors with psychiatric symptoms and quality of life in laryngopharyngeal reflux disease patients

Background: Risk factors for laryngopharyngeal reflux (LPR), such as age, gender, BMI, smoking history and dietary habit affect the severity of LPR. These risk factors have a clinical impact on both social and emotional aspects, which can reduce the quality of life. Thus led the researchers to analyse association between these risk factors with psychiatric symptoms and quality of life for LPR sufferers. Methods: Analytical descriptive research with cross-sectional approach to LPR patients in ENT clinic RSUP Dr. Kariadi Semarang. Sixty six samples aged 18-60 years and met the criteria of the researcher were measured using the DASS 21 questionnaire and the RQS questionnaire. Statistical analysis used the chi-square test. Results: Obtained 66 subjects with a mean age of 45.1 years, there were more women than men (75.8%). Analysis of risk factors associated with depression found gender (p=1.000), age (p=1.000), duration of symptoms (p=1.000), BMI (p=0.132), smoking (p=0.452), and diet (p=1.000). Analysis of risk factors with anxiety obtained gender (p=0.340), age (p=0.743), duration of symptoms (p=0.085), BMI (p=0.322), smoking history (p=1.000), and diet (p=1.000). Analysis of risk factors with stress obtained gender (p=0.798), age (p=0.088), duration of symptoms (p=0.324), BMI (p=0.276), smoking history (p=0.606) and diet (p=0.538). Analysis of the gender association related to the quality of life LPR patients (p=0.032). Conclusions: Duration of symptoms, age, BMI, smoking history and diet were not associated with psychiatric symptoms and quality of life in LPR sufferers. Gender is not associated with psychiatric symptoms but is related to quality of life.
Adsorption of molybdate monomers and polymers on titania with a multisite approach

Adsorption of polymers on mineral surfaces is of great interest. A representative important system is the molybdenum supported titania, used in catalysis. The well-known chemistry of molybdate polymers in aqueous solutions allows a detailed study of the contribution of these polymers to the Mo adsorption on titanium oxide surface. A large range of Mo concentrations was covered: from low levels where only Mo monomers are present to high levels where extensive polymerization takes place. Data from different techniques, like potentiometric titrations, proton-ion titrations, and adsorption edges, were used for the description of the interface "molybdate solution/titania surface". All the data could be modeled very well using the recently introduced CD-MUSIC approach. The charge of the surface complexes is spatially distributed in the interface. MoO42- monomers adsorb over the entire pH range forming inner sphere complexes, which are characterized by two types of structure, i.e., bidentate and monodentate. Below pH 5.5 and high total molybdate concentrations the heptamolybdate polyanion Mo7O23(OH)5- is also adsorbed, forming an outer sphere complex. Due to its relatively large size, it covers a significant number of surface groups
Research Africa Network (RAN) RAN Working Paper

Purpose – This study presents an economic investigation of the entrepreneurship practise of the Igbos of South-Eastern Nigeria. It is intended to deepen entrepreneurial development and employment generation in the country. This study also provides empirical support to situate the Igbo entrepreneurship model ( IEM) among existing entrepreneurship literature, particularly for research in developing countries. Design/methodology/approach – The study adopts a quantitative approach to examine 1187 responses carefully drawn from the Onitsha and Nnewi business clusters in Anambra state. In addition to descriptive demonstrations, the Propensity Score Matching (PSM) technique is employed to estimate the effects of treatment on the treated by pairing treatment and control units with similar attributes on the propensity score and other likely covariates. Specifically, the PSM is used to perform a counterfactual analysis of the effect of the entrepreneurship model on business outcomes by examining participants and non-participants in the IEM. Findings – The key findings of the study indicate that entrepreneurs who participated in the IEM have higher business survival rate, business growth rate and access to trade and informal credit, while non-IEM entrepreneurs have better access to formal credit source than the IEM graduates. Research Limitations/Implications – Generalisation of results can be limited since the study is based on responses of samples drawn from two clusters (Onitsha and Nnewi) in Anambra State, South-East Nigeria. The clusters, though situated in Igbo land, are not the only Igbo business locations in the South-East region and the rest of the country. However, with the larger number of the respondents and synchronisation with existing literature in this subject area guarantee the robustness and applicability of the study findings. Originality/value – The novelty of this study rests on its pioneering attempt to empirically examine how the IEM can drive entrepreneurial development in Nigeria. We also distil lessons for evidenced-based replication of the model to provide a sustainable employment channel for the country. The study posits, among other things, that the IEM can be a veritable approach for enterprise development and youth employment in Nigeria
Cyclic Vomiting Syndrome: A Case Report and Mini Literature Review

A 27-year-old man presented to the emergency department with nausea, vomiting, and abdominal pain. He had been having similar episodes for the last seven years, and all of the previous workups had been unremarkable. After excluding all organic causes of his presentation, the patient was diagnosed with cyclic vomiting syndrome (CVS) and managed accordingly. He has shown remarkable improvement and no further attack has been reported for almost five months since the diagnosis was made. This case report highlights the diagnostic challenge represented by CVS. Also, it summarizes the main aspects of management to achieve and maintain the remission of the condition.
Transformation of the Structure of Self-Attitude in Early, Middle and Later Adulthood (on the Example of the Ukrainian Sample)

The study intends to trace the dynamics of self-esteem and changes in the structure of self-attitude at different stages of adult life, as well as identify signs of experiencing age-related crises. Self-attitude is considered a multidimensional formation, with its individual components, have different subjective significance in different periods of life. A cross-section was carried out in 507 subjects aged 25-65 years was carried out. Rosenberg Self-Esteem Scale and Self-Attitude Study Methodology by Pantileev were used. Normative data for RSES obtained on a sample of adult Ukrainians (N=488) are presented for the first time. The average interval was 22.70±5.43 (with a measuring scale of 0 to 30 points), but the reference point for low self-esteem is different for men and women. Comparison of average results in groups belonging to periods of early, middle, and later adulthood showed that the attitude towards oneself with age becomes more emotionally expressive, concerning both positive and negative components. The indicators of self-blame and inner closedness grow along with the growth of the positive self-attitude (self-confidence, self-management, self-acceptance). The heterogeneous age dynamics of components of self-attitude, pronounced peaks, and dips in different periods are shown. Based on the clustering of empirical data, we described seven types of self-attitude in adulthood: illusory, confident, accepting, crisis, externally oriented, persistently negative, and inexpressive. Markers of experiencing crisis life periods are the ambivalence of self-attitude – the simultaneous manifestation of positive and negative components, which is regarded as a sign of instability. The obtained results demonstrate that there are potential opportunities for personal growth among cases of low self-esteem.
Lipschitz Constrained Neural Networks for Robust Object Detection at Sea

Autonomous ships rely on sensory data to perceive objects of interest in their environment. Deep Learning based object detection in the image domain commonly used to solve this issue. The robustness of such approaches in non-ideal conditions is, however, still to be proven. In this work state of the art methods are applied on the RetinaNet architecture attempting to create a more robust object detection network given noisy input data. The GroupSort activation function and Spectral Normalization is used and the results are compared to the standard RetinaNet network. Our findings show that these modifications perform better and ensure robustness under moderate noise levels, than the standard RetinaNet network.
Preparation and characterization of novel thermoresponsive gold nanoparticles and their responsive catalysis properties

Novel thermoresponsive gold nanoparticles (AuNPs) with lower critical solution temperature (LCST) were obtained through the non-covalent interaction between a thermoresponsive hyperbranched polyethylenimine with isobutyramide groups (HPEI-IBAm) and citrate-protected AuNPs. The LCSTs of the thermoresponsive AuNPs could be conveniently modulated over a broad range by altering the molecular weight of the HPEI core, the degree of substitution (DS) of the IBAm groups of the HPEI-IBAm polymers or the pH of the solution. The obtained thermoresponsive AuNPs could be used as recyclable responsive catalysts for the reduction reaction of 4-nitrophenol by NaBH4. As far as the thermoresponsive catalysts were concerned, reducing the molecular weight of the HPEI core, lowering the DS values and increasing the concentrations of the capping HPEI-IBAm polymers or the gold resulted in the acceleration of the reaction. By choosing the right capping HPEI-IBAm polymers, the reaction was faster than that catalyzed by AuNPs without capping polymers. The reaction rate was accelerated by elevating the reaction temperature at first, but reached a plateau or decelerated upon raising the temperature close to the LCSTs of the thermoresponsive AuNPs catalysts. Moreover, the obtained thermoresponsive AuNP catalysts could be recovered by heating the temperature above their LCSTs and be recycled at least six times with more than 95% conversion.
Genetic Limitations to Athletic Performance

Elite performance is a complex phenotype. It requires athletes to train hard, train well and look after their bodies through appropriate rest and nutrition. However, it also has a well-established genetic component that is larger than most people would estimate. In this chapter we will explore whether genetic variation could limit an individual’s athletic ability. We will consider the determinants of performance; both nature and nurture. We will explore the extent of genetic variation and how it can impact on physiological traits; as well as the issue of responders versus non-responders. We will discuss in detail some of the best know common and rare genetic variants that influence performance as well as the issues around, and strategies being employed in, discovering more. Lastly we will consider the potential for gene doping and for athletes to try to modify their performance through altering their DNA. Much about the genetics of sporting performance remains unknown. Athletes should not feel limited by any genetic information they currently have. In fact they should want to know more.
Understanding the Strategies of Creating Fake News in Social Media

Social media giants like Facebook are struggling to keep up with fake news, in the light of the fact that disinformation diffuses at lightning speed. For example, the COVID-19 (i.e. Coronavirus) pandemic is testing the citizens' ability to distinguish real news from falsifying facts (i.e. disinformation). Cyber-criminals take advantage of the inability to cope with fake news diffusion on social media platforms. Fake news, created as a means to manipulate readers to perform various malicious IT activities such as clicking on fraudulent links associated with the fake news/posts. However, no previous study has investigated the strategies used to create fake news on social media. Therefore, we have analysed five data-sets using Machine Learning (ML) that contain online news articles (i.e. both fake and legitimate news) to investigate strategies of creating fake news on social media platforms. Our study findings revealed a threat model understanding strategies of crafting fake news which may highly likely diffuse on social media platforms.
A Mini-review: Effect of Dunaliella salina on the Growth and Health of Fish

Fisheries is one of the sectors that can be developed to meet world food needs. The development of the fisheries is influenced by the availability of quality feeds. Dunaliella salina is a unicellular green algae that can be used as fish feeds. D. salina is known to contain many nutrients such as protein, carbohydrates, fats, pigments, and others. D. salina has also been shown to increase the growth rate of various types of fish. Not only for growth, but several studies have shown that D. salina has favorable effects on immunology. This article aims to explain the nutritional content and the effect of D. salina on the growth and health of fish. Based on the above studies, D. salina has the potential to be used as an alternative feed for various types of fish.
Efficacy of plant extracts and extracting agents against Colletotrichum gloeosporoides of pawpaw fruits

Pawpaw (Carica papaya L.) is a fruit crop of economic importance in Kenya, where small scale farmers are the major producers. One factor limiting pawpaw production is anthracnose disease caused by Colletotrichum gloeosporoides, whose management on farm still remains a major challenge. The objective of this study was to determine the efficacy of plant extracts and extracting agents for controlling anthracnose disease on pawpaw fruits. In vitro spore germination and in-vivo tests were done using extracts from five plants; Aloe chiliensis, Azadiracta indica, Carissa edulis, Fuerstia africana and Solanum incanum; and extracting agents methanol, chloroform and ethanol against the fungus. A logistic regression model was used to estimate the botanicals’ dose response treatment ranges. The efficacy of the crude extracts was greatest when methanol was used for extraction. The highest inhibition was recorded in pawpaw fruits treated with leaf extracts of F. africana. There were significant differences in effects among treatments by methanolic extracts of the five plants on conidial spore germination percentage. Aloe chilensis (Aloe) showed a higher spore germination of 35.7%; while Azadirachta indica (Neem) resulted in the lowest spore germination of 1.2%. There were significant differences in days to healing of C. papaya fruits infected with anthracnose. Pawpaw infected fruits healed fastest (3.5 days) when treated with the methanolic leaf extracts of F. africana; while A. chiliensis ethanolic leaf extracts resulted in the longest healing time of over 7 days. Although these botanical fungicides present high potentials or controlling anthracnose pathogens of pawpaw fruits, their suitability for application within the socio-economic framework of Kenyan small-scale producers still remains a matter for further investigation.
Influence of Palladium Precursors on Structural Properties and Phenol Hydrogenation Characteristics of Supported Palladium Catalysts

Pd(OOCCH3)2, PdCl2, and Pd(NH3)4Cl2 were used to study the influence of palladium precursors on structural properties and phenol hydrogenation characteristics of Al2O3- and MgO-supported palladium catalysts. Palladium dispersion as well as phenol conversion is higher over MgO-based catalysts with the respective palladium precursors. Pd(OOCCH3)2 shows good metal dispersion and phenol hydrogenation activity over both of the supports. Pd(NH3)4Cl2 leads to lower dispersion of Pd, probably due to the presence of inherent NH3 (a reducing agent) and facile surface mobility of the precursor. The presence of chlorided Pd species in reduced Pd/Al2O3, originating from precursor PdCl2, was confirmed by UV–visible spectroscopy. The initial activity of phenol hydrogenation is directly proportional to the palladium area over the catalysts prepared with Pd(OOCCH3)2 and Pd(NH3)4Cl2; the activity shows a negative deviation over the catalysts originating from PdCl2. Palladium precursors do not have a significant influence on the distribution of products. Al2O3-based catalysts are totally selective for cyclohexanone production, whereas MgO-based catalysts, along with cyclohexanone, produce cyclohexanol as the minor product. A comparison of the product distributions and the overall conversion of phenol over the MgO-based catalysts reveals that changes in product selectivity cannot be attributed merely to a change in the conversion level and also that one product does not form at the expense of another. Al2O3-based catalysts show initial deactivation, while MgO-based catalysts show strong resistance to deactivation.
Comparing the influence of substantive and communicative servicescape on healthcare traveler emotions: the moderating effect of accommodation type and interior design style

Purpose The purpose of this paper is to investigate the relationships between two dimensions of servicescape (i.e. substantive and communicative servicescape), health care travelers’ emotions, perceived value and word-of-mouth intentions. It also assesses the moderating effects of accommodation type (i.e. hotel and Airbnb) and interior design styles (i.e. traditional and modern) on the relationship between the two servicescape dimensions and travelers’ emotions. Design/methodology/approach Using a sample from a survey of 692 health care travelers who stayed at either a peer-to-peer accommodation (i.e. Airbnb) or a hotel, a multi-step structural equation model analysis tested the relationships among variables. It examined the moderating effects of accommodation type and interior design style. Findings The relationships between servicescape, emotions, perceived value and word-of-mouth were significant. Also, the two moderators affected how servicescape influenced the emotions of health care travelers. For Airbnb guests, communicative servicescape had a more substantial effect on enhancing their positive emotions than hotel guests. For health care travelers who stayed at an accommodation with a traditional interior design style, in addition to enhancing positive emotions of health care travelers, substantive servicescape significantly reduced their negative emotions. Practical implications The findings suggest the need for the lodging industry to examine how health care travelers perceive and experience their accommodations with unique interior design characteristics. Also, stakeholders in the lodging industry should leverage the aspects of substantive servicescape in terms of relevant interior design styles, which, in turn, influence health care travelers’ positive word-of-mouth intentions. Given the increase in medical mobility and demand for accommodations by those traveling to receive health care services, understanding the lodging environment and how it affects travelers in this segment is essential. Originality/value This research develops a comprehensive servicescape model with a focus on the communicative dimension. Moreover, this study significantly contributes to the hospitality literature regarding how the core experience and various interior design styles influence a rapidly growing segment of health care travelers. Health care travelers’ emotions are essential to consider given the propensity to experience stress related to travel situational health factors.

This article seeks to synthesize the cultural and creative tourism “state of the art” as a platform for the construction of a theoretical model guiding creative experience. Proposing a theoretical model, the researchers show a way for a better understanding of the complex creative system, without focusing on details but suggesting a global point of view. The aim is to understand the links between the ideas, determine the importance and relevance of arguments and use to approach the problems in a consistent way. The study is based on a diverse documental analysis and literature review
Multiple‐Factor Influence on Air Quality of Road Motor Vehicles Tail Number Limit in Administrative Area of Beijing, China

From December 2, 2013, to October 31, 2019 (total 2160 days), Beijing official air quality data was used as the research object. The article analyzes the end of days 4 and 9 and the end of the nonrestricted 4 and 9 days, working and nonworking days, restricted and nonrestricted working days, long holidays (Spring Festival and National Day), and nonlong holidays (short holidays other than the Spring Festival and National Day and working days) of AQI, PM2.5, PM10, SO2, CO, NO2, and O3. According to the statistical analysis of the data, the air quality of the 4 and 9 limit is worse than that of the non-4 and 9 limit. Motor vehicles restricted in traffic had an objective effect on air AQI, PM2.5, PM10, CO, and NO2, whereas there was almost no difference in O3. Some peak values of AQI, PM2.5, PM10, SO2, CO, and NO2 on nonrestricted working days were significantly higher than those on restricted working days. At the same time, there was a peak time of the impact of motor vehicles on AQI, PM2.5, PM10, SO2, CO, and NO2 in Beijing. This time should be between 3 and 5 days, or 72 and 120 hours.
All-electron Dirac-Fock-Roothaan calculations on the electronic structure of the GdF molecule

The electronic structure of the GdF molecule is investigated using all-electron Dirac–Fock–Roothaan calculations. It is found that, in the ground state, the Gd atom transfers a 5d electron to the 2p spinors of the F atom, so that the molecule is ionic, having the configuration of Gd+F−. However, the molecule is not purely ionic, since the electrostatic field produced by Gd+ and F− causes the spinor energies of F 2s and one of the Gd 5p to be almost energetically degenerate so that these spinors strongly mix with each other and form covalent bonds. The electrostatic field also causes a large energy lowering for one of the 4f spinors, giving further stability to GdF. The 4f electrons of Gd should be regarded as valence electrons. The lower excited states and positively and negatively ionized states are found to be roughly described by Gd atomlike excitations, ionization, and electron attachments.
