Compact slot antenna with enhanced band‐edge selectivity and switchable band‐notched functions for UWB applications

In this study, a new reconfigurable stepped slot antenna with enhanced band-edge selectivity of the UWB passband and switchable band-notched characteristic is presented. Good out-of-band rejection and sharp cut-off at band-edge are achieved by the use of defected ground structure (DGS) and a parasitic slot near the stepped slot. The well-designed DGS not only produces transmission zero to obtain good cut-off property in upper sideband but also provides better impedance matching of in-band. The frequency range of the proposed antenna is from 3.1 to 11.1 GHz (114%) with the reflection coefficient <; - 10 dB. The shape factor is 1.05, which indicates that the proposed design has an excellent selectivity. To obtain the notched band, two passive strip lines near the feeding line are designed. Furthermore, the reconfigurable function with four states can be easily realised by the control of two diodes between the passive strip line and the ground. The structures of the notched band and bias circuit are relatively simple and independent of antenna radiation structure. The performance of the antenna is presented and compared with other competitive antennas. The proposed design has many significant advantages in dimension, good out-of-band characteristics, and controllable states for different UWB applications.
International Journal of Hospitality Management Ethics and Corporate Social Responsibility – an Analysis of the Views of Chinese Hotel Managers

Based on a sample of 257 Chinese hotel managers, this paper examines the ethical principles to which these managers adhered. The premise is that any application of the principles of corporate social responsibility (CSR) will be facilitated or inhibited by the degree to which management holds to a strong ethical stance. Developing a questionnaire derived from different sources such as the Forsyth Ethics Position Questionnaire and the 12 golden standards of Tao Zhugong developed in the 5th century BCE, a principal components analysis of the scores on a 35 item scale indicated five components to ethical perspectives: namely respect for individuals, tolerance of degree of relativity in moral standards, the role of corporations in current society, expediency in business and adherence to CSR.
International Journal of Hospitality Management General Self-efficacy's Effect on Career Choice Goals via Vocational Interests and Person–job Fit: a Mediation Model

Keywords: General self-efficacy Choice goals Vocational interests Person–job fit Human resources management a b s t r a c t This study investigates a new mediation model, in which individuals' career choice goals are proposed to be influenced by the interplays of three influences including general self-efficacy, vocational interests , and person–job fit perceptions. Soon-to-be graduates of Hospitality and Tourism Management (HTM) who just finalized their placement in the industry responded to self-completed questionnaires. They were 302 senior undergraduates from two institutes of higher education in tourism and hospitality on China's Hainan Island. The four indirect causal paths within this mediation model include: (a) general self-efficacy → person–job fit → choice goals, (b) general self-efficacy → vocational interests → choice goals, (c) general self-efficacy → vocational interests → person–job fit, and (d) vocational interests → person–job fit → choice goals. The results of structural equation modeling indicate that these four paths are all statistically significant and all the hypotheses regarding these paths therefore gain empirical support. The study's findings as well as their implications are discussed within the context of self-efficacy theory, career development theory, and human resource development practices in the hospitality and tourism domain.
International Journal of Hospitality Management towards Strategic Intent: Perceptions of Disability Service Provision amongst Hotel Accommodation Managers

The tourism sector globally has become increasingly mindful of how an ageing population is reshaping service provision forms and offerings. This being particularly true of accommodation operations where there is a now a growing recognition of the commercial value for providing market groups with exceptional service. With this in mind, this study sought to ascertain the perceptions of managers in the accommodation sector towards disability service provision with a view to identifying any current service gaps or failings. An inductive, qualitative approach was used with the data collection phase incorporating a series of one on one interviews and a focus group. The in-depth interviews were conducted with 10 managers of hotels deemed to have accessible rooms that complied with the relevant building codes and standards. A focus group comprised 22 managers of hotels located in the Sydney central business district, Australia. Study findings revealed five key themes that had not been previously discussed in the literature. They were: inclusive attitudinal approach; safety; the responsibility of people with a disability to communicate their needs to the hotel; perceptions of accessible rooms by the general public; and operational processes. Related themes that emerged from the data analysis that had previously been aligned with the literature included: legislative responsibility, policy and building codes; disability as a market segment; staff awareness/training; and language, marketing, and promotion information. Implications with respect to management of accessible rooms in the accommodation sector are outlined and further areas of research are proposed.
Assessing Statistical Results: Magnitude, Precision, and Model Uncertainty

ABSTRACT Evaluating the importance and the strength of empirical evidence requires asking three questions: First, what are the practical implications of the findings? Second, how precise are the estimates? Confidence intervals provide an intuitive way to communicate precision. Although nontechnical audiences often misinterpret confidence intervals (CIs), I argue that the result is less dangerous than the misunderstandings that arise from hypothesis tests. Third, is the model correctly specified? The validity of point estimates and CIs depends on the soundness of the underlying model.
International Journal of Hospitality Management Mechanism of Customer Value in Restaurant Consumption: Employee Hospitality and Entertainment Cues as Boundary Conditions

Food quality and employee task performance have been demonstrated to positively influence customer evaluations of restaurant dining experience. This study extends previous research by incorporating customer affective responses to examine the mediating processes underlying the relationships between customer perceptions of task performance/food quality and perceived value. The moderating influences of employee hospitality and entertainment cues on the relationships between customer perceptions of task performance/food quality and their affective responses were also examined. Results from surveying 308 customers of full-service restaurants showed that customer affective responses mediate the relationships between task performance/food quality and perceived value. The results also indicated that the relationship between food quality and affective responses increases with employee hospitability. However, employee hospitability negatively moderates the relationship between task performance and affective responses. Additionally, strong entertainment cues positively reinforce the relationship between task performance and affective responses, but do not significantly affect the relationship between food quality and affective responses.
ESTRUTURA E DISTRIBUIÇÃO ESPACIAL DE UMA POPULAÇÃO DE BLECHNUM TABULARE (THUNB.) KUHN (PTERIDOPHYTA, BLECHNACEAE) EM UM MOSAICO FLORESTA-CAMPO NO SUL DO BRASIL

Blechnum tabulare (Thunb.) Kuhn is a subarborescent fern widely distributed in the “Campos de Cima da Serra” region in State of Rio Grande do Sul, Brazil. This study describes the structure and spatial patterns of a B. tabulare population in the municipality of Sao Francisco de Paula. All young and adult individuals in a total of 60 contiguous 25 m 2 grassland quadrats were sampled and the estimated size recorded for height-frequency distribution analysis. The spatial position of each quadrat was defined by X and Y coordinates and the spatial distribution of the plants plotted by a distance clustering index. A total of 367 individuals were sampled, of which 144 were young (non-fertile) and 223 adult individuals (fertile), which were distributed in four height classes. The higher frequency of juveniles indicated great potential of population recruitment across the area. The young individuals (Ia = 1.41; P = 0.03) were more grouped than adults (Ia = 0.94; P = 0.54), probably due to more adequate conditions for spore germination and sporophyte establishment.
A world of unstable jobs is far from the empirical trends displayed in the Irish labour market in the 21st century

Labour market dynamics are complex, limiting the capacity for consensus on a singular phenomenon to account for patterns. In this paper, we present a range of broader empirical trends from the Irish labour market that suggests the possible impact of neoliberal-type policies in the Irish market has been counterbalanced by strong human capital and skills development, growth in higher level occupations and employment protection. Though precarious work is a feature of parts of the labour market, the theoretical assumptions underpinning precarious work we argue should not be extrapolated to explain changes in job stability in the labour market at large.
Decoration of Poly-3-methyl Aniline with As(III) Oxide and Hydroxide as an Effective Photoelectrode for Electroanalytical Photon Sensing with Photodiode-like Behavior

This study achieved the decoration of poly-3-methyl aniline (P3MA) with As2O3–As(OH)3 using K2S2O8 and NaAsO2 on the 3-methyl aniline monomer. This resulted in a highly porous nanocomposite polymer composite with wide absorption optical behavior, an average crystalline size of 22 nm, and a 1.73 eV bandgap. The photoelectrode exhibited a great electrical response for electroanalytical applications, such as photon sensing and photodiodes, with a Jph of 0.015 mA/cm2 and Jo of 0.004 mA/cm2. The variable Jph values ranged from 0.015 to 0.010 mA/cm2 under various monochromatic filters from 340 to 730 nm, which demonstrates high sensitivity to wavelengths. Effective photon numbers were calculated to be 8.0 × 1021 and 5.6 × 1021 photons/s for these wavelength values, and the photoresponsivity (R) values were 0.16 and 0.10 mA/W, respectively. These high sensitivities make the nanocomposite material a promising candidate for use in photodetectors and photodiodes, with potential for commercial applications in highly technological systems and devices. Additionally, the material opens up possibilities for the development of photodiodes using n- and p-type materials.
TRAVEL IMPACTS OF URBAN FORM: IMPLICATIONS FROM AN ANALYSIS OF TWO SEATTLE AREA TRAVEL DIARIES

The large body of literature reviewed for this paper generally supports the notion that mixed-use or neotraditional neighborhoods can reduce the amount of travel for most households, as measured by the number of miles traveled. The paper also looked at weekend travel for the mixed-use nighborhoods. This analysis showed that travel miles on Saturday were about 25% greater than Sunday, and Saturday travel was 12% greater than the average weekday. This paper also gives credence to the few researchers who have looked at travel time rather than distance as a principal measure. The research has several implications for travel demand modeling. First, in order to model new (old) neighborhood forms, short trips must be handled much better than in the past. Second, if travel time budgets are as uniform as found in this work and shown in others, perhaps they could be used more in the calibration and validation process to assure that models operate within time constraints by various parameters. Third, the travel time budget issues and close ties between land use and short trips reinforce the notion that feedback loops are an increasingly important part of the travel forecasting process.
Etude des altérations hydrothermales à borosilicates des la Humboldt Range (Nevada, USA)

La humboldt range (nevada, usa) presente des gites a or-argent associes a une importante alteration hydrothermale a borosilicates. Cette chaine resulte de la tectonique distensive tertiaire mise en place dans le grand bassin a cette epoque. Durant celle-ci, une activite hydrothermale liee au magmatisme induit une importante alteration de l'encaissant ainsi que le depot de nombreux gites mineraux. L'etude des alterations hydrothermales fait apparaitre une zonalite des parageneses minerales du centre a l'exterieur du systeme. De plus, on peut observer une zonalite verticale des silicates d'aluminium avec un passage de l'andalousite a la pyrophyllite, dans le domaine mesothermal, puis a la kaolinite, dans le domaine epithermal. Les tourmalines et les sericites montrent une variation continue de leur composition depuis le centre vers l'exterieur du systeme hydrothermal. Leur association avec d'autres mineraux peut permettre de preciser des conditions physico-chimiques du milieu. L'etude detaillee des borosilicates s'impose comme un bon guide de cartographie des alterations hydrothermales et trouve son application en prospection miniere. La humboldt range montre de tres grandes similitudes avec d'autres gisements comme novazza, ben lomond, montana tunnels, etc. Un type de gisement dont les gites a au-ag-zn et u-mo-zn sont deux sous types, peut etre defini. Ses caracteristiques sont le contexte tectono-magmatique et le type d'alteration hydrothermale
Associations of Adipocytokines and Early Renal Dysfunction in Young People on the Background of Dyslipidemia

Background: There are data supporting the idea that atherogenic dyslipidemia is a risk factor for CKD and reduced GFR. The aim was to evaluate the associations between adipocytokines and early renal dysfunction in young people with dyslipidemia. Materials and methods: A population study was conducted in IIPM—Branch of IC&G SB RAS, in 2013–2017. Furthermore, 1033 people were included in the study (469 men (45.4%) and 564 women (54.6%)). The study included blood sampling, anthropometric data, and adipokines by multiplex analysis. Results: Among people with reduced kidney function and DLP, men were 3.1 times more common than without DLP, women smoked 2 times less often, arterial hypertension was 7.8 times more common, and abdominal obesity was 2.7 times more common (and women with DLP were 3 times more likely than those without DLP). An increase in the level of resistin by 1 mcg/mL was associated with an increased chance of having renal dysfunction by 0.2%. An increase in the level of GIP was associated with an increased chance of having renal dysfunction by 1.1%. Conclusions: In young people with dyslipidemia, regardless of the presence of abdominal obesity, resistin and GIP are associated with the presence of renal dysfunction.

It will also have a section on the initial and ongoing psychological impact on the patient from a diagnosis of genital warts, an often over-looked aspect of holistic care. The article aims to provide guidance on assessment and management of genital warts and to increase awareness of the mental health impacts that may be associated with the diagnosis.
Effectiveness of Self-Collected, Ambient Temperature–Preserved Nasal Swabs Compared to Samples Collected by Trained Staff for Genotyping of Respiratory Viruses by Shotgun RNA Sequencing: Comparative Study

Background The SARS-CoV-2 pandemic has underscored the need for field specimen collection and transport to diagnostic and public health laboratories. Self-collected nasal swabs transported without dependency on a cold chain have the potential to remove critical barriers to testing, expand testing capacity, and reduce opportunities for exposure of health professionals in the context of a pandemic. Objective We compared nasal swab collection by study participants from themselves and their children at home to collection by trained research staff. Methods Each adult participant collected 1 nasal swab, sampling both nares with the single swab, after which they collected 1 nasal swab from 1 child. After all the participant samples were collected for the household, the research staff member collected a separate single duplicate sample from each individual. Immediately after the sample collection, the adult participants completed a questionnaire about the acceptability of the sampling procedures. Swabs were placed in temperature-stable preservative and respiratory viruses were detected by shotgun RNA sequencing, enabling viral genome analysis. Results In total, 21 households participated in the study, each with 1 adult and 1 child, yielding 42 individuals with paired samples. Study participants reported that self-collection was acceptable. Agreement between identified respiratory viruses in both swabs by RNA sequencing demonstrated that adequate collection technique was achieved by brief instructions. Conclusions Our results support the feasibility of a scalable and convenient means for the identification of respiratory viruses and implementation in pandemic preparedness for novel respiratory pathogens.
Stereotactic Body Radiotherapy for Lymph-Nodal Oligometastatic Prostate Cancer: A Multicenter Retrospective Experience

Background: The favorable role of SBRT for lymph-nodal oligometastases from prostate cancer has been reported by several retrospective and prospective experiences, suggesting a more indolent natural history of disease when compared to patients with bone oligometastases. This retrospective multicenter study evaluates the outcomes of a cohort of patients treated with stereotactic body radiotherapy for lymph-nodal oligometastases. Methods: Inclusion criteria were up to five lymph-nodal oligometastases detected either with Choline-PET or PSMA-PET in patients naïve for ADT or already ongoing with systemic therapy and at least 6 Gy per fraction for SBRT. Only patients with exclusive lymph-nodal disease were included. The primary endpoint of the study was LC; a toxicity assessment was retrospectively performed following CTCAE v4.0. Results: A total of 100 lymph-nodal oligometastases in 69 patients have been treated with SBRT between April 2015 and November 2022. The median age was 73 years (range, 60–85). Oligometastatic disease was mainly detected with Choline-PET in 47 cases, while the remaining were diagnosed using PSMA-PET, with most of the patients treated to a single lymph-nodal metastasis (48/69 cases), two in 14 cases, and three in the remaining cases. The median PSA prior to SBRT was 1.35 ng/mL (range, 0.3–23.7 ng/mL). Patients received SBRT with a median total dose of 35 Gy (range, 30–40 Gy) in a median number of 5 (range, 3–6) fractions. With a median follow-up of 16 months (range, 7–59 months), our LC rates were 95.8% and 86.3% at 1 and 2 years. DPFS rates were 90.4% and 53.4%, respectively, at 1 and 2 years, with nine patients developing a sequential oligometastatic disease treated with a second course of SBRT. Polymetastatic disease-free survival (PMFS) at 1 and 2 years was 98% and 96%. Six patients needed ADT after SBRT for a median time of ADT-free survival of 15 months (range, 6–22 months). The median OS was 16 months (range, 7–59) with 1- and 2-year rates of both 98%. In multivariate analysis, higher LC rates and the use of PSMA-PET were related to improved DPFS rates, and OS was significantly related to a lower incidence of distant progression. No G3 or higher adverse events were reported. Conclusions: In our experience, lymph-nodal SBRT for oligometastatic prostate cancer is a safe and effective option for ADT delay with no severe toxicity.
Impact of the business environment and tax incentives on new investments: Evidence from developing countries

This research aims to measure the impact of the business environment and tax incentives on new investments in Kosovo. A questionnaire created especially for this study was submitted to 104 companies that have invested in Kosovo during the period 2018–2020. It is designed to be as comprehensible and accessible as possible and is divided into an introduction that provides demographic data of the respondent, and types of surveyed businesses, to go through the questions related to new investments, and business environment, and the last section contains questions related to tax incentives. The reliability of the questionnaire is measured by Cronbach’s alpha. In terms of the methodology, a multifactorial regression model and correlation analysis are employed. Based on the multiple regression model, the research results show that the independent variables, such as business environment and tax incentives, have a significant positive impact on the dependent variable, new investments. Furthermore, the correlation analysis between new investments and tax incentives also indicates a strong positive relationship. Additionally, the business environment and tax incentives are the main factors attracting new investments. The results of this study can help to enhance the business climate and boost tax incentives, demonstrating Kosovo’s suitability as a location for new investments. There remains the duty of the government and policymakers to create mechanisms that ensure sustainable business conditions and applicable tax incentives.
A privacy preserving data aggregation and query for metro passenger flow via mobile crowdsensing

With the popularity of mobile Internet networks and mobile terminal equipment, mobile crowdsensing (MCS) has become a popular and economical way of data collection, sharing, and query services. However, the existing privacy‐preserving query schemes MCS‐based less consider the sensing user's privacy leakage at data aggregation phase and querier's privacy leakage at query service phase simultaneously. In this article, we propose a novel privacy‐preserving aggregation and query scheme applied in metro passenger flow via MCS, which achieves the metro passenger flow acquisition and query service and protects the sensing user's identity and location privacy as well as the querier's query privacy. We exploit Paillier cryptosystem and pseudonym mechanism to prevent the privacy leakage, and utilize secure kNN algorithm to protect the query privacy. Meanwhile, we achieve the sensing user accountability based on digital signature algorithm and credible management. The privacy analysis demonstrates that our scheme satisfies the privacy‐preserving and security requirements. The performance evaluation and experimental result show the efficiency of our scheme in practice.
