Gender euphoria: a grounded theory exploration of experiencing gender affirmation

ABSTRACT Gender euphoria is a term increasingly used in transgender and gender diverse (TGD) communities. Experiences of gender euphoria are often overlooked during clinical assessment and most academic research tends to focus solely on discussions of gender dysphoria. The primary aim of this study is to use grounded theory combined with photo-elicitation methodologies to gather a more nuanced understanding of experiences of gender euphoria in the lives of TGD individuals. Data for this study was collected via online photo-elicitation interviews with TGD adults (n = 30). Descriptive and visual data clarify gender euphoria as a concept as well as reveal the ways in which it is experienced among TGD adults. The primary themes emerging from the study yield the following four key processes, which explain experiences of gender euphoria: 1. Being exposed to a gender affirming antecedent, 2. Having an affirming thought, 3. Feeling a positive emotion, and 4. Experiencing enhanced quality of life. Participants’ discussions elicited through self-selected images contribute to a more meaningful understanding of gender affirmation in the lives of TGD people. Findings highlight the relationship between gender affirmation, gender euphoria, and the potentiation for long-term positive change.
An Automatic Load Detector Design to Determine the Strength of Pedestrian Bridges Using Load Cell Sensor Based on Arduino

The basic requirement that must be met in the construction of a bridge is the resilience. This resilience depends upon the supporting of bridge when the load that passes over the bridge. Loading condition on bridge is generally in the form of dynamic which ​​can vary according to crossing conditions on it. This reason validates in difficulties in estimation the lifetime of the bridge. In order to maintain the good condition of the bridge the estimation of overloading condition and its effects of over loading on bridge need to evaluate to keep the bridge durable for that a bridge load measuring detector is needed. The aim of this research is to design an automatic load detector to test the strength of the bridge at dynamic loading conditions. The load detector designed through an Arduino-based load cell sensor. The detector equipped with I2C LCD display mechanism which can display the load on bridge and buzzer switch with warning alarm which can alert when bridge is over loaded. The total sensor mechanism was tested on a miniature wooden bridge with selected loads. During testing, the detector load cell sensors placed at the bottom of the bridge surface with a running load, the readings are considered recorded for several load cells at dynamic loading conditions. In the research work was carried out on the bridge using various load ranges from 100 grams to 25 kilograms on load cells at various positions. From the experimentation it has been noticed that, the load cell has displayed the smaller value as compared with the actual value due to the load distribution over the bridge structure. From the experimental data it is noticed that the average error rate 4.67%, hence the developed sensor system more suitable for practical application to evaluate the damage of the bridge. It also concluded that, the detector is more effective in evaluation of dynamic loading condition to prevent damage of bridge.
Modern foreign language learning: exploring the possible impact of parental experiences on student motivation

ABSTRACT Purpose This present paper draws on a doctoral study which provides an innovative insight into the extent to which parents influence their child’s motivation to learn a foreign language. Methodology An exploratory methodology was adopted to approach this study from multiple angles, using a sequential mixed-methods research design. A questionnaire, co-created by a professional community of practice, was administered to parents (n = 107) and children (n = 495) in four secondary schools in the wider West Midlands conurbation. This was followed by semi-structured dyadic interviews with six sets of parents and their children (n = 12). This gave a rounded view of parental orientations towards language learning and how this could impact their child’s motivation. Findings Quantitative analysis shows that there are strong, positive correlations between parent and child data for five of the six motivation constructs. Linear regression shows that parental level of general education has a statistically significant impact on four student motivation constructs. Results from the qualitative analysis show that parents were largely indifferent, with mixed experiences of language learning. Parents were also cognisant of issues surrounding the availability of different language options and possible timetabling constraints which impact the flexibility for children to choose a language. Originality The present study is innovative through its inclusion of parental views towards learning a foreign language. Its research design paves the way for a widening of methodologies through the use of mixed methods to explore these orientations in greater detail as well as drawing on a professional community of practice as a partner in the research process.
Attitudes towards Aboriginal and Torres Strait Islander peoples in Australia: a systematic review

ABSTRACT Objective Aboriginal and Torres Strait Islander peoples have been the longstanding targets of racism and discrimination in Australia. This paper presents the findings of a systematic literature review designed to identify and synthesise the available evidence exploring these intergroup attitudes, and the factors that correlate with them. Method Searches were conducted in Medline, Psychology and Behavioural Sciences Collection, ProQuest Psychology Database and PsycINFO databases. Eligible studies were required to measure attitudes of non-Indigenous Australians towards Aboriginal and Torres Strait Islander peoples. Results Twenty studies met the eligibility criteria (n = 2,958). The results outlined: (a) the prevalence of negative attitudes, (b) attitudes were most commonly conceptualised as modern racism, and (c) that there are a range of factors that are associated with negativity towards Aboriginal and Torres Strait Islander peoples. Conclusions The review outlined the relationship between attitudes towards Aboriginal and Torres Strait Islander peoples and demographic, ideological, individual differences, and intergroup factors. This review highlights the need for continued research in this domain to inform appropriate prejudice reduction strategies. KEY POINTS What is already known about this topic: Aboriginal and Torres Strait Islander peoples face continued adversity, prejudice, and discrimination on their own land. This heightened propensity to be targeted for prejudice is a known social determinant of poorer health and wellbeing. Understanding racial attitudes towards this group is an imperative step in understanding and combating this health disparity. What this topic adds: There is a paucity of academic research exploring negativity towards Aboriginal and Torres Strait Islander peoples The limited quantity of evidence does establish a range of correlates with negative attitudes that can be clustered into four themes – demographic factors, ideological variables, individual differences factors, and intergroup factors. More research is warranted in this domain to further establish a body of evidence on intergroup attitudes towards Aboriginal and Torres Strait Islander peoples, with a renewed focus needed on prejudice reduction techniques.
The Quality of Entrepreneurship Development Service Vocational High School: Assesment with Servqual Model

The objective of this study is to find out the quality level of entrepreneurship development of the students and graduates in Vocational High School (VHS). Methodologically, this study used ServQual (service quality) with 701 respondents from seven districts with cluster sampling method. There are five instruments and dimensions in this study which are physical/tangible feature, reliability, responsiveness, credibility, and empathy. The whole data analyzed statistically by descriptive statistic and comparative analysis. The finding of this result is there is a significant difference between the respondents’ reality and expectation. It turned out with the average value of respondents' expectations of the 5 (five) dimensions of entrepreneurship service quality in which it is much higher than the average value of reality/perception. Therefore, it is concluded that the level of entrepreneurship service quality is not sufficient. From the five service dimensions, tangible and interest-responsiveness got the lowest assessment. The implication of the results is that it needs reinforcement for the five dimensions of the entrepreneurship development service in order to attain competitive-graduates. Moreover, the applying of ServQual model needs to be expanded in education and entrepreneurship services. Received: 17 October 2021 / Accepted: 22 December 2021 / Published: 5 March 2022
3D Flow Structures During Upwelling Events in Lakes of Moderate Size

Upwelling can impact water quality dynamics in stratified water bodies. Conceptual models generally classify the upwelling response to winds in lakes into either a non‐rotational (2D, closed‐basin) model or a rotational (coastal upwelling) counterpart. The non‐rotational model is broadly applied in rotationally influenced lakes. The upwelling response to winds in stratified lakes may exhibit elements of both conceptual models. Here, we present the results of simulations with an accurate three‐dimensional numerical model of a lake of moderate size (Lake Tahoe, California–Nevada, USA), and focus our analyses on addressing the influence of the Coriolis force during the upwelling setup and relaxation phases. Upwelling was observed at the upwind boundary as well as along the coast to the left of the mean wind direction due to Ekman‐driven divergence. On the downwind shoreline, where downwelling occurs, alongshore currents appeared in response to wind forcing. Following the relaxation of the wind, our simulations reveal, for the first time, the existence of powerful cyclonic alongshore currents in lakes of moderate size, which are found to be in quasi‐geostrophic balance. These currents followed the characteristics of coastal jets often observed in large lakes and the coastal ocean. Our work leads us to conclude that upwelling setup in lakes with length scales ≈20 km and Burger numbers S < 1, exhibits a combination of dynamics predicted by both the non‐rotational, 2D, closed basin model, and the rotational coastal‐upwelling conceptual model.
Persistent Anti-Littering Activism in a Non-Western Context: The Case of the Nature Cleaners Movement in Iran

Abstract Persistent activism has mostly been discussed in the context of Western socio-political and religious movements, where it is attributed to organizational and inter-personal networks and the development of identities and solidarities. Studies of persistent environmental activism are rare in countries that lack durable mobilizing structures. This study explores, for the first time, persistent anti-littering activism in an infrequently studied social and political setting, Iran. This allows us to assess the applicability of social movement findings from western cases to a non-western context. Drawing on in-depth interviews with eighteen persistent Iranian anti-littering activists we find that cosmopolitanism, which de-naturalizes pollution and littering, is a key motivating factor. Persistent anti-littering activism involves overcoming the difficulties of participation by finding pleasures in generating, together, a pragmatic identity.
Deep defects in InGaN LEDs: modeling the impact on the electrical characteristics

Deep defects have a fundamental role in determining the electro-optical characteristics and in the efficiency of InGaN light-emitting diodes (LEDs). However, modeling their effect on the electrical characteristics of the LED is not straightforward. In this paper we analyze the impact of the defects on the electrical characteristics of LEDs: we analyze three single-quantum-well (SQW) InGaN/GaN LED wafers, which differ in the density of defects. Through steady-state photocapacitance (SSPC) and light-capacitance-voltage measurements, the energy levels of these deep defects and their concentrations have been estimated. By means of a simulation campaign, we show that these defects have a fundamental impact on the current voltage characteristic of LEDs, especially in the sub turn-on region. The model adopted takes into consideration trap assisted tunneling as the main mechanism responsible for current leakage in forward bias. For the first time, we use in simulations the defect parameters (concentration, energy) extracted from SSPC. In this way, we can reproduce with great accuracy the current-voltage characteristics of InGaN LEDs in a wide current range (from pA to mA). In addition, based on SSPC measurements, we demonstrate that the defect density in the active region scales with the QW thickness. This supports the hypothesis that defects are incorporated in In-containing layers, consistently with recent publications.
Impact of biocontrol on the seed regenerative capacity of Lantana camara L. (sensu lato) (Verbenaceae)

ABSTRACT The combined impact of biocontrol agents on the seed regenerative capacity, i.e. seed production, seed-rain, soil seedbank, seed germination and seedling density, of Lantana camara L. (sensu lato) (Verbenaceae), was measured in the field in an inland area of South Africa. The study was conducted on 10 plots (20 × 50 m each) along part of the Sabie River catchment. The most prevalent biocontrol agents at the site were Aceria lantanae (Cook) (Acari: Trombidiformes: Eriophyidae), Hypena laceratalis Walker (Lepidoptera: Noctuidae), Octotoma scabripennis Guérin-Méneville (Coleoptera: Chrysomelidae), Ophiomyia camarae Spencer (Diptera: Agromyzidae) and Teleonemia scrupulosa Stål (Hemiptera: Tingidae). Using the insecticidal exclusion method, comparisons of seed regenerative capacity were made between exclusion (insecticide treated) and biocontrol (untreated) plants over a three-year period. Lantana camara seed production per plant was slightly lower in biocontrol (5831 ± 844 seeds) compared to exclusion plants (6718 ± 1571 seeds), seed-rain density was significantly lower in biocontrol (1080 ± 122 seeds m−2) compared to exclusion plants (1419 ± 154 seeds m−2). Seed germination was lower in biocontrol (98 ± 41 seeds m−2) compared to exclusion plants (116 ± 38 seeds m−2). Seedling density was higher in biocontrol (36 ± 14 seedlings m−2) compared to exclusion plants (32 ± 11 seedlings m−2). Adult plants appeared to suppress their own seedlings. This study showed that the impact of the current suite of biocontrol agents on the recruitment potential of L. camara is minimal, emphasising the need for additional agents, better adapted to the cooler high altitude inland environmental conditions.
Simulation and optimization of an axial impedance pump

In this research the fluid – structure interaction in a multi layer axial impedance pump is analyzed numerically. The fluid dynamics solver Fluent is coupled with the structure mechanics solver Abaqus. Based on the results from these simulations the flow rate is optimized as a function of the excitation frequency. The efficiency of the pump at resonance frequency is determined. To investigate the functioning of the pump at resonance frequency both Fourier analysis and wave intensity analysis are used.
Empirical Study of Factors Influencing Schedule Delays of Public Construction Projects in Burkina Faso

AbstractA well-functioning construction industry is a prerequisite for the development process to take place. In this regard, the aim of this study is to identify the most frequent, severe, and important causes of schedule delays affecting public constructions projects in Burkina Faso to enhance the managerial capability of project managers. This research was conducted by questionnaire survey to solicit the causes of schedule delays from 140 Burkinabe experts (clients, contractors, and consultants). After analyzing their frequency, severity, and importance index using a quantitative statistical method, the top five most important delay factors were ranked as follows: financial capability of the contractor, financial difficulties of the owner, equipment availability of the contractor, slow payments for completed work, and poor subcontractor performance by the contractor. A comparison of the causes of schedule delays in 11 countries to validate the results of the study showed that financial capability of th.
High-density passive multi-fiber assembly to single-mode polymer waveguides using embedded v-grooves for co-packaged optics

We propose a novel high-density and low-profile multi-fiber passive assembly technology to polymer waveguides. We developed a small-sized ferrule with a footprint of only 5 × 5 mm and a thickness of 0.5 mm. An embedded 12 v-groove silicon chip was employed as a receptacle, and we formed the facet of waveguides on the v-groove chip. The optical properties for the proposed structure were experimentally demonstrated. The propagation loss of the single mode waveguides was as small as 0.5 dB/cm for the wavelength of 1310 nm and the average connecting loss of 3.06 dB was obtained.
Screening of Cooling Technologies in Europe: Alternatives to Vapour Compression and Possible Market Developments

The aim of this study is to investigate, review, and assess the recent advances of alternative cooling technologies using traditional vapor compression (VC) systems as a baseline. Around 99% of the final energy consumption used for cooling in the current European market (European Union plus the United Kingdom (EU27 + UK) is supplied by VC technologies. In comparison, the remaining 1% is produced by thermally driven heat pumps (TDHPs). This study focuses on providing a complete taxonomy of cooling technologies. While the EU heating sector is broadly explored in scientific literature, a significant lack of data and information is present in the cooling sector. This study highlights technologies that can potentially compete and eventually replace VC systems within the decade (2030). Among others, the most promising of these are membrane heat pump, transcritical cycle, Reverse Brayton (Bell Coleman cycle), and absorption cooling. However, the latter mentioned technologies still need further research and development (R&D) to become fully competitive with VC technologies. Notably, there are no alternative cooling technologies characterized by higher efficiency and less cost than VC technologies in the EU market.
Studies on Growth and Yield Response of Jatropha curcas Plant on Fly Ash Amended Soil

ABSTRACT Fly Ash (FA) is usually considered unfavorable to plant growth and its disposal has become a serious environmental issue. However, some studies on revegetation on fly ash dumps showed some agricultural potential of the fly ash. The present study attempts to judiciously utilize the waste fly ash as a soil amendment and assess the feasibility of growth of energy plants viz. Jatropha on fly ash amended soil in varying percentages (0%, 5%, 10%, 20%). The study primarily focuses on growth and yield to judge the suitable content of fly ash favoring plant growth. Plastochron Index (PI) and plant morphological characteristics are used to assess the growth whereas, the yield is assesses based on biomass and other parameters estimated after completion of the experimental duration. The growth and yield assessment indicated better sustenance of Jatropha plant on soil amended with 10% fly ash
Lurkers or posters? How teacher identity influences self-presentation on social networking sites

ABSTRACT The ways in which educational practitioners represent themselves on social networking sites (SNSs) continue to provoke discussion and potential controversy. This study investigates how English as a Foreign Language (EFL) teachers in Vietnam manage their self-presentations within SNSs for professional learning purposes. Participants in this mixed methods study included 19 teachers in four focus-group interviews, and 393 respondents to an online survey. We applied teacher identity to interpreting teachers’ self-presentation on virtual platforms. Our findings reveal that although participants frequently use SNSs for professional learning, they prefer a lurking presence and less visible interaction. It is also evident that self-presentation on SNSs is not simply ‘represented’ or ‘reflected’. Rather, these teachers prefer their self-presentation to fit with how they are perceived in Vietnamese society. Teachers’ self-presentation within SNSs is thus robustly mediated by culture. The study contributes to the ongoing interest in teachers’ increasing use of SNSs in their professional lives.
Vitamin D Supplementation for 12 Months in Older Adults Alters Regulators of Bone Metabolism but Does Not Change Wnt Signaling Pathway Markers

Vitamin D status and supplementation regulates bone metabolism and may modulate Wnt signaling. We studied the response of hormonal regulators of bone metabolism, markers of Wnt signaling and bone turnover and bone mineral density (BMD) and bone mineral content (BMC) in a randomized vitamin D intervention trial (12,000 IU, 24,000 IU, 48,000 IU/mo for 1 year; men and women aged >70 years; n = 379; ISRCTN35648481). Associations with total and free 25(OH)D concentrations were analyzed by linear regression. Baseline vitamin D status was (mean ± SD) 25(OH)D: 40.0 ± 20.1 nmol/L. Supplementation dose‐dependently increased total and free 25(OH)D concentrations and decreased plasma phosphate and parathyroid hormone (PTH) (all p < 0.05). The procollagen 1 intact N‐terminal (PINP)/C‐terminal telopeptide (CTX) ratio, C‐terminal fibroblast growth factor‐23 (cFGF23), and intact FGF23 (iFGF23) significantly increased with no between‐group differences, whereas Klotho was unchanged. 1,25(OH)2D and PINP significantly increased in the 24 IU and 48,000 IU groups. Sclerostin (SOST), osteoprotegerin (OPG), receptor activator of NF‐κB ligand (RANKL), BMD, BMC, and CTX remained unchanged. Subgroup analyses with baseline 25(OH)D <25 nmol/L (n = 94) provided similar results. Baseline total and free 25(OH)D concentrations were positively associated with 1,25(OH)2D, 24,25(OH)2D (p < 0.001), vitamin D binding protein (DBP) (p < 0.05), BMD, and BMC (p < 0.05). Associations with PTH (p <0.001), cFGF23 (p < 0.01), and BAP (p < 0.05) were negative. After supplementation, total and free 25(OH)D concentrations remained positively associated only with 24,25(OH)2D (p < 0.001) and DBP (p < 0.001) and negatively with estimated glomerular filtration rate (eGFR) (p < 0.01). PTH and SOST were significantly associated only with free 25(OH)D. There were no significant relationships with BMD and BMC after supplementation. The decrease in PTH and increase in PINP/CTX ratio suggest a protective effect of supplementation on bone metabolism, although no significant effect on BMD or pronounced changes in regulators of Wnt signaling were found. The increase in FGF23 warrants caution because of its negative association with skeletal and cardiovascular health. Associations of total and free 25(OH)D with biomarkers were similar and known positive associations between vitamin D status and BMD were confirmed. The change in associations after supplementation might suggest a threshold effect. © 2022 The Authors.
