Authors: Dent Jackie , Smeeton Nigel , Whiting Lisa , Watson Tim
Published: May 2023

Background/Aims

Surveys are a popular method of collecting data to explore factors associated with midwives' emotional wellbeing. However, existing survey instruments lack consideration of how working practices may influence outcomes. This study aimed to test the face and content validity of a new instrument by assessing midwives' comprehension of bespoke survey items.

Methods

A total of 24 cognitive interviews were conducted with midwives working across the UK. A framework matrix method facilitated descriptive and explanatory analysis of the interpretation of survey items. Interviews were followed by a discussion group with midwifery academics to help identify optimal wording of one problematic survey question.

Results

A range of potential comprehension and response problems were identified, resulting in modifications and the addition of new survey items.

Conclusions

Cognitive interviews can be an effective method to confirm the relevance and usability of bespoke survey items and offer opportunities to improve wording to reduce potential sources of error, thus enhancing the face and content validity of surveys.
Zum fachphraseologischen Einsatz des Öl-Wortschatzes.
Authors: Russo Eriberto
Published: May 2023

This contribution intends to examine the lexical universe of oil, while paying attention both to production practices (expressions, terms, etc., which are directly related to the production of oil, from the harvest to the packaging phase) and to commercialization practices or expressions etc. used to represent the product from an organoleptic and gustatory point of view. The terminological and phraseological analysis is anticipated by a reflection on the relationship between technical language and phraseology and on the presence of the lexeme Öl in the German language. Excerpts from specialist websites are used to carry out the first terminological and phraseological analysis (concerning the production of oil); the second part of the analysis (product marketing) is carried out by taking the product’s descriptions (different types of oil) of websites into account.

Published: May 2023

Recently, there has been growing interest and attention towards daytime radiative cooling. This cooling technology is considered a potentially significant alternative to traditional cooling methods because of its neither energy consumption nor harmful gas emission during operation. In this paper, a daytime radiative cooling emitter (DRCE) consisting of polydimethylsiloxane, silicon dioxide, and aluminum nitride from top to bottom on a silver-silicon substrate was designed by a machine learning method (MLM) and genetic algorithm to achieve daytime radiative cooling. The optimal DRCE had 94.43% average total hemispherical emissivity in the atmospheric window wavelength band and 98.25% average total hemispherical reflectivity in the solar radiation wavelength band. When the ambient temperature was 30°C, and the power of solar radiation was about 900W/m2, the net cooling power of the optimal DRCE could achieve 140.38W/m2. The steady-state temperature of that could be approximately 9.08°C lower than the ambient temperature. This paper provides a general research strategy for MLM-driven design of DRCE.

Published: May 2023

Background

Choose to Move (CTM), an effective health-promoting intervention for older adults, was scaled-up across British Columbia, Canada. Adaptations that enable implementation at scale may lead to ‘voltage drop’—diminished positive effects of the intervention. For CTM Phase 3 we assessed: i. implementation; ii. impact on physical activity, mobility, social isolation, loneliness and health-related quality of life (impact outcomes); iii. whether intervention effects were maintained; iv) voltage drop, compared with previous CTM phases.

Methods

We conducted a type 2 hybrid effectiveness-implementation pre-post study of CTM; older adult participants (n = 1012; mean age 72.9, SD = 6.3 years; 80.6% female) were recruited by community delivery partners. We assessed CTM implementation indicators and impact outcomes via survey at 0 (baseline), 3 (mid-intervention), 6 (end-intervention) and 18 (12-month follow-up) months. We fitted mixed-effects models to describe change in impact outcomes in younger (60–74 years) and older (≥ 75 years) participants. We quantified voltage drop as percent of effect size (change from baseline to 3- and 6-months) retained in Phase 3 compared with Phases 1–2.

Results

Adaptation did not compromise fidelity of CTM Phase 3 as program components were delivered as intended. PA increased during the first 3 months in younger (+1 days/week) and older (+0.9 days/week) participants (p<0.001), and was maintained at 6- and 18-months. In all participants, social isolation and loneliness decreased during the intervention, but increased during follow-up. Mobility improved during the intervention in younger participants only. Health-related quality of life according to EQ-5D-5L score did not change significantly in younger or older participants. However, EQ-5D-5L visual analog scale score increased during the intervention in younger participants (p<0.001), and this increase was maintained during follow-up. Across all outcomes, the median difference in effect size, or voltage drop, between Phase 3 and Phases 1–2 was 52.6%. However, declines in social isolation were almost two times greater in Phase 3, compared with Phases 1–2.

Conclusion

Benefits of health-promoting interventions—like CTM—can be retained when implemented at broad scale. Diminished social isolation in Phase 3 reflects how CTM was adapted to enhance opportunities for older adults to socially connect. Thus, although intervention effects may be reduced at scale-up, voltage drop is not inevitable.
Design and fabrication of a GaN HEMT power amplifier based on hidden Markov model for wireless applications

Published: May 2023

Improvement of power amplifier’s performance is the desired topic in communication systems. There are many efforts are made to provide good input and output matching, high efficiency, sufficient power gain and appropriate output power. This paper presents a power amplifier with optimized input and output matching networks. In the proposed approach, a new structure of the Hidden Markov Model with 20 hidden states is used for modeling the power amplifier. The widths and lengths of the microstrip lines in the input and output matching networks are defined as the parameters that the Hidden Markov Model should optimize. For validating our algorithm, a power amplifier has been realized based on a 10W GaN HEMT with part number CG2H40010F from the Cree corporation. Measurement results have shown a PAE higher than 50%, a Gain of about 14 dB, and input and output return losses lower than -10 dB over the frequency range of 1.8–2.5 GHz. The proposed PA can be used in wireless applications such as radar systems.

Published: May 2023

Introduction

The association between occupational mechanical exposures and chronic low back pain (LBP) has been widely studied, however, few systematic reviews have evaluated the evidence of an association. Furthermore, little is known of the impact of occupational psychosocial exposures on chronic LBP. The aim of this systematic review and meta-analysis is to study the association between occupational mechanical and psychosocial exposures and chronic LBP.

Methods

The study will be conducted as a systematic review using another systematic review published in 2014 as basis and has been registered in the International Prospective Register of Systematic Reviews (PROSPERO) with registration number CRD42021281996. A systematic literature search will be performed in 6 scientific databases to identified potential relevant studies published after 2014. Studies will systematically be excluded through a screening process performed independently by 2 reviewers. Exposures will include occupational mechanical and psychosocial exposures, and outcome will include chronic LBP (LBP ≥3 months, “degenerative” diseases, and lumbosacral radiculopathy). Study population will include persons in or above working age, and study designs will comprise cohort and case-control studies. The quality of each included study will be methodologically assessed by 2 independent reviewers and level of evidence of an association will be graded using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system. In meta-analyses, effect sizes will be addressed using random-effect models, sensitivity analyses will explore the robustness of the meta-analysis, and heterogeneity assessed.

Discussion

This systematic review and meta-analysis will assess the evidence available of the association between occupational mechanical and psychosocial exposures and chronic LBP. The review can provide essential knowledge on the association, exposure-response relationships, thresholds, which may pave the way for political decisions on the occupational environment and the labour market insurance policy.

Published: May 2023

Introduction

Scoliosis Research Society-22 revised (SRS-22r) is the common questionnaire used to evaluate health related quality of life (HRQOL) for young people with adolescent idiopathic scoliosis (AIS). The aim of this study is to evaluate its content validity for this population.

Methods

In-depth semi-structured interviews were conducted with a purposive sample of young people with AIS (Cobb angle ≥25˚, aged 10–18 years). Concept elicitation was used to evaluate the influence of AIS on participants’ HRQOL. Participant information sheets and consent/assent forms were age relevant. Topic guide was informed by the SRS-22r and existing evidence. Interviews were audio and video recorded, transcribed verbatim, coded, and analysed using thematic analysis. Derived themes/codes were compared with SRS-22r contents (domains/items).

Results

Eleven participants (mean age 14.9 years [SD = 1.8]; 8 female) were recruited. The mean curve size was 47.5° [SD = 18°] and participants had been managed via different approaches. Four main themes emerged with associated subthemes: 1) Physical effects related to physical symptoms (back hurt, stiffness) and body asymmetry (uneven shoulders), 2) Activity-related effects showed impact on mobility (sitting for long periods), self-care (dressing), and school activities (focus during lessons), 3) Psychological effects revealed emotional (feel worried), mental (sleep quality), and body image effects (hide back from others), 4) Social effects (participation in school and leisure activities), and school, friends and mental health support. A weak association was found between items of the SRS-22r and the identified codes.

Conclusion

The SRS-22r does not adequately capture important concepts that relate to HRQOL of adolescents with AIS. These findings support revision of the SRS-22r, or the development of a new patient reported outcome measure to evaluate HRQOL of adolescents with AIS.
Love, jealousy, satisfaction and violence in young couples: A network analysis
Authors: Ventura-León José , Lino-Cruz Cristopher
Published: May 2023

In recent years, couples have been affected by health measures related to COVID-19, a circumstance that forces us to examine couple interactions in terms of crucial variables of their functioning. In this sense, the present study aimed to examine the association between love, jealousy, satisfaction, and violence in young couples through network analysis. A total of 834 young people and adults between 18 and 38 years of age (Mean = 20.97, SD = 2.39) participated; 646 women (77.50%) and 188 men (22.50%), who completed the Sternberg’s love scale (STLS-R), Brief Jealousy Scale (BJS), Relationship Assessment Scale (RAS) and Woman Abuse Screening Tool (WAST-2). A partial unregularized network was estimated using the ggmModSelect function. The Bridge Strength index was calculated because the aim was to identify the bridge nodes between the variables under study. The results reveal that two nodes of the love variable, Commitment, and Intimacy, had a direct and moderate relationship with the Satisfaction node. The latter is the central node in the network. However, in the male group, the most intense associations are in Satisfaction-Intimacy, Violence-Passion, Jealousy-Commitment. It is concluded that there are relevant connections between the nodes of the network, which invite further research on couple relationships after the COVID-19 pandemic.

Authors: Ruiz Saura José Enrique
Published: May 2023

El presente trabajo de investigación analiza la forma en que los nuevos escenarios laborales aparecidos en los últimos, sobre todo, de la mano de la economía de plataformas virtuales, ejercen su influencia en las formas de organización de acciones colectivas por parte de las personas trabajadoras. Para ello, se indaga en el surgimiento y desarrollo de conflictos en la economía 4.0. Puede concluirse que, estos nuevos sistemas de trabajo eminentemente digitales están provocando el desplazamiento de las formas clásicas del sindicalismo. Esta circunstancia es una respuesta a los límites del nuevo marco sociolaboral, en el cual las plantillas tienen unas condiciones contractuales más heterogéneas, la persona trabajadora se encuentra más “atomizada” y, además, los canales de comunicación se reducen habitualmente a empresa-persona trabajadora en dirección descendente.

ABSTRACTSince log file monitoring is indispensable in the developmentand repair of an application, it is also of paramount importanceto obtain a clear and direct interpretation when analyzing thefiles. Often due to the increase in data generated per second incurrent systems and the dispersion that cloud computing cancause in these files, this action can become quite complicated,having to analyze the file several times until the reported error isfound. This task can take a long time, depending on the numberof files, data, and components available on the system. In thisstudy, the Elastic Stack log management tools were used:Elasticsearch, Filebeat, and Kibana for filtering, managing,centralizing, and viewing the logs. The tests were performed onLexisNexis' Big Data HPCC Systems platform. With the creationof interactive dashboards, the log visualizations and the searchfor errors were facilitated, which can help find solutions forreported errors.

Abstract
In evolutionary robotics, the combination of geneticalgorithms, neural networks, and mobile robots is widespread.Recent studies revealed that the length of the agent evaluationepisode and the manner in which it is varied during evolutiondirectly affects the evolution performance and the behaviorgenerated. The length of the episode influences both the accuracyof the fitness function as well as the quality of the generatedbehaviors. However, more investigation is still needed to bettercomprehend the full impact of different episode duration. Thegoal of this paper is to analyze and characterize the behaviorsgenerated in robots evolved under varying the length of theevaluation episode. The agents all aim at solving locomotionproblems. Results showed that reducing the episode length helpsto develop initial behaviors that may perform fairly well, but aregenerally not fully developed. Longer evolutionary episodes tendto produce more static stay-at-a-fixed-position robotic behaviors,preventing further development. On the other hand, experimentsthat gradually increase episode duration over the course ofevolution avoid the optimal static standing location, allowingmore efficient behaviors to develop at the end of evolution.Key Words—Artificial intelligence, Adaptive robotics, Evolutionaryalgorithms

ABSTRACTPrimary Progressive Aphasia (PPA) refers to a group of clinical syndromes caused by a neurodegenerative disease and is categorized into 3 types: APP-S, APP-NF/A, and APP-L. The Grammar Reception Test, in the Brazilian version (TROG2-Br), which focuses on the detection of problems in the Portuguese-Brazilian language, was used in individuals with PPA. The objective of this work is to show the feasibility of using Machine Learning algorithms to classify APP types, based on the individual's performance in the TROG-Br test. For this, the algorithms of Decision Tree, Naive Bayes, kNN, and SVM are applied and evaluated. The results are promising and show that it is possible to classify the types of APP using the individual's performance in the TROG-Br test as predictive attributes.

Published: May 2023

Road transportation does an excellent job of connecting Savar's inner and outer areas, but it might be difficult for commuters to decide which mode of transportation to employ because residents of Savar come from a wide range of socioeconomic backgrounds. It is necessary to do in-depth research on the characteristics of people in the study region who choose different modes of transportation to achieve the goal of selecting a certain mode for their travel. Where a person lives can have a significant impact on their typical patterns of travel behavior. People who live closer to the center of things have access to a wider variety of amenities than those who live further away, and as a consequence, their travel patterns are distinct from one another. The study's findings indicate that several factors, including income, age, gender, and vocational qualities and goals, influence a commuter's preferred method of transportation. When it comes to selecting a mode of transportation, the most predictable factors to take into account are trip time and cost. After conducting research, it was found that most excursions are made from this place to Motijheel, Tejgaon, and Savar Export Processing Zone for their services, businesses, and jobs, respectively.

Published: May 2023

Polímeros termoplásticos aromáticos como o poli (éter-éter cetona) PEEK têm se mostrado muito promissores para a produção de membranas trocadoras de prótons (PEM), devido as suas propriedades. Estudos demonstram que polímeros modificados quimicamente podem apresentar características originais melhoradas. O processo de funcionalização por sulfonação é uma das estratégias de modificação de materiais poliméricos, que promove maior hidrofilicidade, melhor condutividade iônica, maior molhabilidade e melhor desempenho como PEM. O PEEK foi tratado com ácido sulfúrico, obtendo-se o SPEEK. O polímero foi titulado a fim de estudar seu grau de sulfonação (SD), avaliar sua relação com a capacidade de troca iônica (IEC) e sua potencial aplicação como PEM. Amostras de 0,3 g SPEEK foram imersas em solução de cloreto de sódio para a realização da troca protônica. Foram realizadas as titulações das soluções salinas com hidróxido de sódio e, através do volume obtido, foram obtidos sua IEC = 0,5435 meq.g-1 e seu SD = 0,61. Comprovou-se que a relação entre a massa de polímero, grau de sulfonação e capacidade de troca iônica pode ser modificada, em razão da otimização da quantidade disponível de polímero e que, tendo o conhecimento do SD do polímero é possível estimar a quantidade de base a ser consumida, que está relacionada quantidade de prótons oriundos do SPEEK e presentes na solução salina.
The official EFL textbook in cameroonian technical schools and the needs of dressmaking students: an evaluation of interactions in English lère
Authors: Hagbe Edwige Damaris
Published: May 2023

The present paper examines the contents of the Premiere textbook of EFL in order to find out if it fits the needs and interests of the students of the technical fields such as bespoke tailoring and dressmaking. Over the years, the indifference of technical students towards English has been a topical issue and still raises debates nowadays. The aim of this paper is to show that the existence of a single book for all Premiere classes can account for the lack of interest in English generally observed in technical schools. Emphasis is laid on the analysis of themes, the reading passages and the selection of pictures in Interactions in English Ière. In other words, this research attempts to show that the official textbook of English for francophone technical education is not tailored to the needs and interests of the learners. The research methodology consisted in reading and analysing the selected corpus in a bid to find out if its content pleases the intended audience made up of dressmaking students. The EFL students and teachers were also interviewed in order to probe their attitudes towards the selected English book. The paper ends with suggestions on how to improve on the English book for that specific set of students. The aim is to raise more awareness in the educational circle, create more motivation in the target learners and ameliorate their performances in English.

The objective of this present study was to investigate the haemato-biochemical indices and intestinal microbial population of broiler chickens fed diets supplemented with Prosopis africana (African mesquite) essential oil (PAEO). A total of 540 one-day old broiler chicks of Ross 302 strain were allotted to six treatments with 6 replicates consisting of 15 birds each in a completely randomized design. Feed and water were given ad libitum, and all necessary management practices were strictly observed throughout the experiment, which lasted for 8 weeks. The birds in treatment 1 (T1) was fed a basal diet with no PAEO, T2 was fed basal diet plus 1.2 g kg-1 Oxytetracycline, T3, T4, T5 and T6 were fed basal diet plus PAEO at 200 mg, 400 mg, 600 mg and 800 mg kg-1 respectively. All haematological parameters and intestinal microbial population were influenced by the dietary treatments (p ˂ 0.05). Total protein, triglycerides, cholesterol and urea were significantly different (p < 0.05) across the dietary treatments and are within the physiological ranges reported for healthy chicken. However, serum tryglycerides, low density lipoprotein, high density lipoprotein, magnesium and chloride ion values were not affected by PAEO (p ˃ 0.05). It was concluded PAEO possess several properties – antioxidant, antimicrobial, hepatoprotective, immune-stimulatory, anti-inflammatory and physiological amongst others all of which are vital for the health enhancing effects in birds. Prosopis africana essential oil can be supplemented up to 800 mg kg-1 in the diets of broiler chickens without causing any deleterious effect on their blood profile.

The leaf N and P concentration and the N:P ratios were assessed as a first approach to evaluate the nature of nutrient limitation. A total of 96 sites and 131 dominant plant populations (belonging to 50 herbaceous macrophyte species) were sampled in medium hydrometric level conditions. The interspecific variability of leaf nutrients was higher than the intraspecific variability. Foliar N ranged from 0.5% to 5.3%, while foliar P ranged from 0.1% to 0.5%. Leaf N:P was 9.3 ± 4.3 (mean ± standard deviation), suggesting N-limitation for most of the plant populations –under the assumption of the validity of the critical N:P thresholds previously proposed (N:P < 10 for N limitation, N:P > 20 for P limitation). Neither the leaf nutrients nor the N:P were affected by the flooding frequency, hydrometric water level, or wetland landscape unit/subunit location. The species identity accounted for most of the leaf nutrient and N:P variability, followed by the sampling date for P and N:P levels. This study provides a baseline on the nature of nutrient limitation, mainly by N, in plants of the Lower Paraná River floodplain. Future surveys or experiments could address the variations of leaf nutrients and nutrient limitation in contrasting hydrological conditions.

The genus Ilex (Aquifoliaceae) has several species appreciated by their ornamental value and nutraceutical and medicinal properties. Southern South America is a major center of biodiversity, with ca. 13-15 species. However, they have been scarcely studied, particularly regarding cytogenetics. For instance, chromosome numbers have been solely documented in eight species, while the DNA content (genome size or 2C-value) has been recorded just for three species. To contribute to the characterization of Ilex species from southern South America, here we established the genome size of I. brasiliensis, I. brevicuspis, I. integerrima, I. microdonta, I. pseudobuxus, I. taubertiana and I. theezans as novel data, and verified the DNA content for I. argentina, I. dumosa and I. paraguariensis. Our results indicate that the mean DNA content at the interspecific level ranges between 1.691 pg, as in I. pseudobuxus and 3.600 pg as in I. theezans. Yet, an individual of I. theezans from Paraguay showed about half the genome size. These unexpected outcomes for I. theezans lead us to propose the coexistence of diploid and polyploid cytotypes for this species. I. brasiliensis was determined to have 2n=40 chromosomes and regular meiosis, for the first time. In sum, this work is a contribution to the knowledge of an understudied plant family. Gaining insight on genetic biodiversity is relevant for the potential use of non-industrialized species for the improvement of economically significant ones.

Domain Specific Hope Levels of University Students in Turkey: The Predicting Roles of Personal Belief in a Just World and Gender
Authors: MUYAN-YILIK Mine , DEMİR Ayhan
Published: May 2023

The aim of the current study was to investigate the predicting roles of personal belief in a just world and gender in university students’ hope levels in specific life domains (i.e., social relationships, romantic relationships, family life, academics, work life, and leisure activities). The participants were 168 university students from a major state university in Turkey. Data was collected with the Domain Specific Hope Scale, the Personal Belief in a Just World Scale, and a personal information sheet. Results of Multivariate Regression Analysis showed that both personal belief in a just world and gender were significant predictors of domain specific hope levels of university students. More specifically, personal belief in a just world was found to significantly predict university students’ hope levels in academics, family life and leisure activities. In addition, female students were found to have higher hope levels in social relationships. Taken together, the findings highlighted the importance of studies on domain specific hope levels. Current findings were discussed within the context of the hope and just-world literature and gender roles in Turkey.

The aim of this study is to examine the science learning styles of eighth grade students in terms of gender, having a study room, having internet access and future expectation variables. For this purpose, survey design was used. The sample of the study consisted of 584 eighth grade students in Kayseri. Grasha Reichmann Learning Styles Scale developed in 1996 and adapted to Turkish by Vural (2013) was used as a data collection tool. In the analysis of the data, descriptive statistical techniques and cross-table analysis were performed. It has been found that the students use collaborative and competitive learning styles at a high level and they use independent, dependent, avoidant, and participative learning styles at moderate level. In addition, while the dominant learning style of most of the students is dependent learning style. In terms of demographic variables, students' learning style preferences differ in terms of gender, having internet access, and future expectation, but it does not differ in terms of having an independent study room variable.
Sociological Inferences Deduced from Creative Writing Activities: Analyzing Gender Perceptions and Stereotypes of Children in terms of Child Development
Authors: GÜRKAN Senem
Published: May 2023

Being a sample for the field of sociology of education, this research aims at analyzing the gender perceptions and gender stereotypes of students through their creative writing activities. The participants of the study chosen by purposeful sampling technique are 97 3rd grade students who study at a primary state school in Samsun, Turkey. A child of 9 years has knowledge of a person’s behavior that is equal to his/her gender stereotypes in terms of child development. So, the participants were chosen intentionally of this age group. As the 82 writings of the students were valid for this research, the sample of the study is 82 writings, 43 of which were collected from girls and 39 of which are from boys. Carried out through qualitative and quantitative, that is, mixed type research paradigms, the design of this study is content analysis. As the data collection technique, document analysis is employed to the free topic creative writing activities of children. During data collection period and procedures, the students were free to choose the topic and the setting was their own classroom to create a natural accommodation. The parents of the students were asked to receive their consents before the activity. As for the data analysis, content analysis was also used as the data analysis technique. The children’s writings were examined for five categories evaluated from the previous studies in literature. These categories were choice of the topic, frequency of male and female characters, attributes, occupational roles and domestic roles. The findings of the study, in short, show that stereotypical differences and gender perception differences occur in the creative writings of children.
The Relationships between Students’ Epistemological Beliefs and Conceptions of Learning in Different Science Domains
Authors: KAPUCU Serkan
Published: May 2023

This study aims to investigate the relationships between 9th grade students’ epistemological beliefs and conceptions of learning in different science domains (physics, chemistry, biology). A total of 462 students (male=247, female=215) participated in the study. Data were collected with the help of the questionnaires that measure students’ epistemological beliefs and conceptions of learning. Pearson correlation analysis was performed to determine the relationships between students’ epistemological beliefs and conceptions of learning in different science domains. The results revealed that there were positive and moderate relationships between students’ epistemological beliefs in “justification” and “development” dimensions and their higher-level conceptions of learning. However, these beliefs were weakly correlated or not correlated to the students’ lower-level conceptions of learning. Similarly, students’ epistemological beliefs in “source” and “certainty” dimensions were weakly associated or not associated with their conceptions of learning.
