Fairness Definitions for Digital Mental Health Applications

Digital applications are becoming a standard part of the diagnosis, treatment, support of people dealing with mental health issues. While doing this they can potentially generate and use significant amounts of data about the user, their state, and their behaviour. Statistical models based on this data are likely to be used for a range of purposes, ranging from prediction of patient outcomes, to personalization of treatment. With such models, there comes a risk of introducing problems of inequality and bias. As unfair systems which lead to worse health outcomes for some groups of people have long existed in healthcare, such bias may emerge due to the historical data used to create models. Addressing fairness in the design of digital mental health tools requires a clear framework for defining and assessing fairness. In this paper we will categorise fairness definitions as applied in digital mental health. We move away from the existing models of grouping definitions based on likeness of measurement and towards a model of grouping based on likeness of design goal for a system. We propose three categories for fairness definitions that are reflective of healthcare concerns. We divide fairness definitions into the categories based on; 1) those that assume equal impact of error across users, 2) those that assume a homogeneous demographic, and 3) those that have a scope beyond the immediate decision. We then apply this categorisation to an existing case study.
Investigation of destination image mediating effect on tourists’ risk assessment, behavioural intentions and satisfaction

: Purpose : The purpose of the present study is to establish a model for the risk assessments of tourists and to determine whether destination image has a mediating effect in the relationship between perceived risk, behavioural intentions, and satisfaction. Methods : The study has a quantitative research design in which data were collected through questionnaires. To ensure the construct validity of the proposed model, first, confirmatory and exploratory factor analyses were performed, and then the structural equation modelling technique was used. Amos 22 and SPSS 22.0 programs were used for the analysis of the data. Results : As a result of research analysis, it has been found that cognitive image had a partial mediating role between the behavioural intentions and satisfaction the tourists (between perceived risk and satisfaction) whereas affective image had no mediating impact between the tourists’ perceived risks, behavioural intentions, and satisfaction. Implications : This study has some theoretical and practical contributions. Considering that the halal tourism literature is a very new concept, it is thought that a model proposal for the field will contribute to the deepening and development of the literature on the one hand and will provide important concrete data to hotel managers and destination policy makers on the other hand. works as an assistant professor at Siirt University, School of Tourism and Hotel Management in Siirt in Turkey.

Cogging Torque Minimization Design in Interior Permanent Magnet Motor by Using an Analytical Method

This paper presents a new magnetic equivalent circuit (MEC) model for calculating the cogging torque in an interior permanent magnet synchronous motors (IPMSMs). Since the proposed method can take into account the slotting effect and magnet end effect, the analysis and design of IPMSMs can be conducted correctly and rapidly despite no use of a finite element method (FEM). Its validity was confirmed by comparing the results of the proposed method with those of FEM. Furthermore, the optimal design result considering various objectives is elicited by using the proposed method.
The Relationship between Tourist Satisfaction and Service Quality with Recommendation Intention: Study of a Cultural Heritage Site**

Recommendation intention Tourist satisfaction Service quality Cultural heritage sites Abstract The purpose of this study is to analyze the relationship between service quality and tourist satisfaction with the recommendation intention of a cultural heritage site. For this purpose, the data was obtained through a structured questionnaire and applied face-to-face to domestic and foreign tourists. The sample is consisted of 400 tourists visiting Bergama cultural heritage sites in August 2019. The chi-square test of independence method was utilized in the analysis of the developed hypotheses. The findings of the present study revealed that there is a relationship between the recommendation intention of the cultural heritage site with the satisfaction of tourists considering the expenses and time spent. The other finding displayed the relationship between service quality and the recommendation intention of the cultural heritage site. As a result, providing tourist satisfaction and service quality, which has a statistically significant relationship with the recommendation intention of tourists, appeared to be among the main objectives of cultural heritage sites as tourist destinations.
Nitrogen Nutrition of Young Special Reference to Citrus Fruit with Asparaginel

Asparagine was the predominant constituent of the free amino acids in young fruit of Citrus unshiu Marc. In early August, asparagine increased exponentially with total N in the fruit peel, suggesting that it can be used as an indicator of the nitrogen status of young fruit. 15N data showed that the primary assimilation of ammonium was catalyzed by glutamine synthetase, and asparagine was also actively formed in the early stages of nitrogen assimilation. Nitrate assimilation occurred to a lesser extent than ammonium assimilation in the hour-order experiment using excised fruit. In the day-order experiment, however, nitrate taken up via the roots was assimilated in greater amounts than ammonium. 14C-asparagine was rapidly metabolized to different compounds, such as aspartate, acidic and neutral compounds, and alcohol-insoluble compounds. However, considerably less CO2 was formed from asparagine than from aspartate. Our data show that asparagine is not a dead-end-
AUGMENTED REALITY BASED INDOOR NAVIGATION USING POINT CLOUD LOCALIZATION

People of various ages may find it difficult to navigate complex building structures as they become more prevalent. The future belongs to a world that is artificially facilitated, and Augmented Reality will play a significant role in that future. The concept of Indoor Navigation using a smartphone-based Augmented Reality technology is explored in this research. Using readily available and affordable tools, this study proposes a solution to this issue. We built an Augmented Reality-based framework to assist users in navigating a building using ARWAY, a software development toolkit. To find the shortest paths, we used the Point Cloud Localization and A* pathfinding algorithms. A shop inside a shopping Centre, a particular room in a hotel, and other locations can be easily located using this app, and the user is given fairly precise visual assistance through their smartphone to get to his desired spot. The proposed framework is based on augmented reality, and point clouds are the most important components. The application allows the user to choose their desired destination as well as change their destination at any time. To find the results from the technical, subjective, and demographic responses, we used hypothesis testing and validation with statistical analysis and exploratory data analysis methods.
An Experiment Study on the Air Conditioning System Performance of R-134a and MC-134 Refrigerant in D8R Caterpillar Units

Refrigerant is a crucial cooling component for the refrigeration cycle. In heavy equipment, the cooling system still relies on the R-134a unit with many weaknesses, including global warming effects and other air conditioning system problems. An alternative substitute for R-134a has been found, i.e., a hydrocarbon refrigerant or MC-134. This product has several advantages compared to R-134a, especially its environmentally friendly aspect. It does not contribute to the damage of the ozone layer and is completed with good physical characteristics and thermodynamic properties. Overall, it has better performance than R-134a, proven on the Nissan Evalia unit. This study aims at testing heavy equipment, especially the D8R caterpillar unit because limited studies discuss heavy equipment regarding its MC134 performance. This research was carried out at the Petrosea Ltd workshop. The research was done through experimental methods. The first stage was retrofitting R134a with MC-134 on the D8R caterpillar unit. The data collection was conducted ten times with an interval of 3 minutes. The second step WAS using MC-134 and taking the same data as the first step. The compressor work on the MC-134 increased by 145.96% compared to R-134a. The result of the study showed that the heat energy released by the condenser using MC-134 increased by 157.833%. 161.625% for the refrigeration effect, and 5.21% for the COP value, respectively, compared to R-134a.
PRACTICAL CONSIDERATIONS FOR DETERMINING POLARIZATION PROPERTIES FROM MEASURED LINEAR COMPONENTS

Polarization properties (e.g. axial ratio, sense, and tilt) of an antenna under test (AUT) are often calculated from measurements with a linear (or dual-linear) polarized range antenna. At first, these calculations appear to be simple and straightforward. However, there are several different conventions used in the literature and some important practical aspects of the measurements are often omitted. Neglect of these small details can easily lead to incorrect results, with the most common error being the reversal of the right-hand-circular and left-hand-circular polarization components. We note the differences in the published polarization conventions and provide practical tips for good polarization measurement practices. We also describe stepby-step procedures for determining AUT polarization properties from two styles of polarization measurements using a linear (or dual-linear) polarized range antenna.
Properties of Poly-γ-Glutamic Acid Producing-Bacillus Species Isolated From Ogi Liquor and Lemon-Ogi Liquor

Poly-γ-glutamic acid (γPGA) is a natural and promising biopolymer synthesized by Bacillus spp. during fermentation. This study isolated Bacillus spp. from ogi steep liquor (OSL) and lemon-ogi steep liquor (LOSL) using standard methods and determined the γPGA-producing ability. The antimicrobial and angiotensin-converting enzyme (ACE) inhibitory activities of γPGA polymer were evaluated and isolates were sequenced. Four isolates (TA004, TA006, TA011, TA012) selected based on phenotypic characterization and stickiness (<15 cm) showed antibacterial activity against different pathogens with the highest activity found in TA004 (22.5 mm) and least in TA011 (16.6 mm). Furthermore, time-kill assay showed that the combined γPGA polymer was more effective and demonstrated bactericidal activity over individual γPGA which are bacteriostatic in nature. All γPGA polymer exhibited ACE properties except TA011. The highest IC50 was observed in TA006 (0.11 mg/ml) and least in TA004 (0.35 mg/ml). TA004 had the highest molecular weight (261 kDa) while TA011 had the least (194.97 kDa). In addition, all γPGA exhibited characteristic peaks at 3413–3268 cm-1 and 1722–1664 cm-1 that corresponded to amine N–H stretching intensities and C = O stretching in COOH. Bacillus isolates were identified as TA004 (B. subtilis-GenBank: MH782061), TA006 (B. amyloliquefaciens- GenBank: MH782075), TA011 (B. subtilis- GenBank: MH782088), TA012 (B. subtilis- GenBank: MH782083). OSL and LOSL have the potential for developing functional foods with a valuable effect on health.
MSM: A Multi-entity Scholarly Model for Systematic Understanding of Evolving Scholarly Networks

Scholarly networks contain massive scholarly information that can be mainly categorized into three entities, i.e., paper , author and topic , which exhibit a co-evolution over time. Although scholarly networks have attracted much attention over the past years, most works focus on single entity of the network, e.g. sub-networks generated by citation, co-authorship or topic relationship [1–5]; while few of them incorporate different entities into an entirety to provide a systematic understanding of scholarly networks at scale. We bridge this gap by proposing a multi-entity scholarly model (MSM) with strong theoretical guarantees, which amalgamates entities of paper, author and topic into one single framework to simulate interactions among different entities, and thus presenting the co-evolution within scholarly networks. First of all, using real scholarly datasets — Microsoft Academic Graph 1 [6] with 126 million publications, we observe properties that belong exclusively to scholarly networks, such as varying and converging exponents of power-law distributions with time, degree densification in each of the three aforementioned entities. We also observe interesting evolving patterns like simultaneous co-evolution of all the three entities, faster growth rate of entities with larger size, etc. Based on our observations, we propose the MSM that jointly captures both intra and inter correlations among different entities during the evolving process. Through both theoretical analysis and empirical simulation, we further characterize the MCM as capable of reproducing evolving patterns of real multi-entity scholarly networks.
Influence of Working Conditions on the Commitment of Administration Police Officers in Meru County Kenya

The study sought to determine the influence of working conditions on the commitment of administration police officers in Meru County Kenya. Descriptive research design was used in the study. The target population was 1178 administration police officers of different ranks out of which 10% of the entire population in the county was used as the sample size. Questionnaire was used to collect primary data from the police officers. The study revealed that interpersonal relations and compensation had a statistically significant relationship with both the normative commitment and affective commitment. The relationship between physical conditions and workload did not have statistically significant relationship with either normative commitment or affective commitment. With regard to continuance commitment, only compensation had a statistically significant relationship, otherwise the other independent variables had relationship that was not statistically significant. Overall, only workload (p = 0.02), interpersonal relations (p = 0.00), and compensation (p = 0.00) had a statistically significant relationship with commitment as their respective p-values were all less than 0.05. Huge workload negatively affected officer’s commitment to the administration police service. Compensation level greatly influenced officer’s level of commitment to the police service as shown by majority of the officers indicating that they were not satisfied with compensation level. Good interpersonal relations existed among the administration police officers and this enhanced commitment to the police service. The study recommends that organization should ensure that employees are properly compensated. Organizations should also ensure that staff gets adequate workload. While allocating day-to-day duties, supervisors should keep in mind human relations and understand that there is life after work. People have emotions, and thus interpersonal relations with other employees will enhance organization commitment.
Assessment of nutritional status among adult Hos of Paschim Medinipur District, West Bengal, India

The tribal population in India, as per 2011 census is 104.3 million, constituting 8.6% of the total population. Overall, 89.97% of them live in rural areas. Nutrition has been a major health issue in India for centuries. Chronic hunger and under-nutrition are the worst tribulation of the poverty that still plagues millions of tribal households in India. The objective of this study was to assess the anthropometric characteristics and nutritional status of the population. The present cross-sectional study was carried out at 2 blocks (Debra and Dantan II) of Paschim Medinipur District, West Bengal, India. A total 392 adults (Female= 207; Male= 185) Ho tribal people were included in this study. The mean (SD) value of height (cm), weight (kg), mid-upper arm circumference [MUAC (cm)], body mass index [BMI (kg/m2)] was higher among males 159.68 (5.64), 54.53 (8.00), 24.79 (2.56) and 21.37 (2.85) respectively, than females 149.16 (5.42), 46.01 (7.98), 22.00 (2.76) and 20.65 (3.19). These values were statistically significant (p<0.0001). Based on MUAC, the prevalence of undernutrition was higher among females (55.6%) than males (26.5%) and this was statistically significant (p<0.001). However, based on BMI, the prevalence of undernutrition was higher among females (27.5%) than males (16.8%), which was statistically significant (p<0.05) also. According to WHO classification of chronic energy deficiency (CED), the rate of under nutrition indicated a serious situation. Thus, to reduce the nutritional stress among this ethnic group, appropriate nutritional intervention programmes are needed to be initiated.
What are the barriers and enablers that people with a lower limb amputation experience when walking in the community?

Abstract Purpose: To explore barriers and enablers to community walking perceived by people with lower limb amputation. Materials and methods: Three focus groups (n = 14 participants), using purposive sampling, were conducted with people with lower limb amputation who used a prosthesis to walk in the community. Three investigators analyzed transcripts using thematic content analysis. Results: Themes aligned with the International Classification of Functioning, Disability and Health domains. Barriers related to body function and structure included prosthetic function, residual limb integrity, phantom limb pain and other medical issues, with optimal prosthetic function and adequate fitness identified as enablers. Personal barriers included challenges adjusting to change, whereas personal enablers included being able to adjust to change, having a positive attitude, goal setting and a purpose for community walking. Environmental barriers included physical (e.g., terrain, crowds, climate) and social (e.g., unwanted attention and finances). Environmental enablers included aids, transport, preparation, social support and finances. Community walking was essential to participation in work, leisure, social activities and family roles. Conclusion: Walking in the community for people with a lower limb amputation presents many barriers, but enablers have also been identified. Targeted assessments and interventions, and appropriate environmental planning may assist in minimizing barriers to community walking. Implications for rehabilitation Although rehabilitation for people with lower limb amputation should continue to optimise body function and structure (such as strength, fitness, pain and prosthetic function) to help prepare individuals for walking in the community, personal and environmental factors should also be addressed. Optimising an individual’s personal enablers may facilitate community walking; this may include strategies to assist with adjusting to change, setting goals, instilling a positive attitude towards walking, and seeing a purpose for walking in the community. Enhancing environmental (physical and social) enablers and minimising environmental barriers to walking in the community may be possible through environmental planning (e.g. infrastructure such as lifts), social awareness and education.
Bipartite Containment Tracking with Prescribed Performance of Nonlinear Multi-Agent Systems with Hysteresis Inputs

Under signed digraphs, a class of bipartite containment tracking problem of nonlinear multi-agent systems is investigated in this paper. Each agent with unknown nonlinear dynamics is modeled by a strict-feedback system preceded by hysteresis input uncertainty. A low-complexity distributed control law is proposed to achieve bipartite containment tracking with a prescribed performance metric. Additionally, all closed-loop signals are guaranteed to be ultimately bounded. Simulation results illustrate the validity of the proposed distributed algorithm.
Preparation of Non-Toxic Fluorescent Peptide-Coated Silica/PEG Nanoparticles from Peptide-Block Copolymer Conjugates

Peptide-decorated nanosystems have demonstrated higher stability and improved cellular uptake as compared to bare NPs and appear highly promising in diagnostics and theranostics of cancer. Herein, we discuss the preparation and structural characterization of peptide-functionalized silica/PEG NPs, starting from peptide–block copolymers, prepared in turn by conjugation of the peptides to block copolymers before NP formation. This synthetic design allowed full control of density and composition of peptide surface coverage. Preliminary experiments support the low toxicity of the fluorescent peptide–NPs and their ability of cell internalization.
COMPARATIVE STUDY OF DIFFERENTIAL BOOST INVERTERS

Output voltage of traditional full bridge inverter is less than input DC voltage. In applications when input voltage is low, the front end step up converter is usually required presenting a two stage power conversion. Dual boost inverter (DBI) can realize single stage conversion, which has the advantages of simple structure, less power devices and boost ability. The traditional modulation strategy of DBI makes all power switches operate in high frequency and sustain high voltage or current stress, which leads to heavy conduction and switching loss. So the Half Cycle Modulation (HCM) strategy can be used, which makes power switches work in high frequency just in half cycle, and can reduce the switching and conduction losses power devices greatly. Furthermore, to reduce the current circulation loss in DBI, an improved DBI with two clamping switches is can be used based on HCM, which can bypass the inductor current with low stress switches, therefore the loss caused by circulation current can be greatly reduced. The simulation of a dual boost inverter with half cycle modulation technique has been used to find out the losses and the boosting of the output. The simulations are done by using MATLAB/SIMULINK software. DBI prototype has been implemented in the lab. The advantages of the HCM strategy and improved DBI with two clamping switches are verified using experimental results.
