Green Synthesis and Antibacterial Activity of Noble Metal Nanoparticles using Plants
Authors: Morteza Naghib Seyed , Garshasbi Hamid Reza
Published: October 2023

The emerging properties of noble metal nanoparticles (NPs) are attracting
huge interest from the translational scientific community and have led to an
unprecedented expansion of research and exploration of applications in biotechnology
and biomedicine. An array of physical, chemical and biological methods has been used
to synthesize nanomaterials. In order to synthesize noble metal NPs of particular shapes
and sizes, specific methodologies have been formulated. Although ultraviolet
irradiation, aerosol technologies, lithography, laser ablation, ultrasonic fields, and
photochemical reduction techniques have been used successfully to produce NPs, they
remain expensive and involve hazardous chemicals. Therefore, there is a growing
concern about developing environment-friendly and sustainable methods. Since the
synthesis of nanoparticles of different compositions, sizes, shapes and controlled
dispersity is an important aspect of nanotechnology, new cost-effective procedures are
being developed. Microbial synthesis of NPs is a green chemistry approach that
interconnects nanotechnology and microbial biotechnology. Biosynthesis of gold,
silver, gold–silver alloy, selenium, tellurium, platinum, palladium, silica, titania,
zirconia, quantum dots, magnetite, and uraninite nanoparticles by bacteria,
actinomycetes, fungi, yeasts, and viruses have been reported. However, despite
stability, biological NPs are not monodispersed, and the rate of synthesis is slow. To
overcome these problems, several factors, such as microbial cultivation methods and
extraction techniques, have to be optimized, and the combinatorial approach, such as
photobiological methods, may be used. Cellular, biochemical and molecular
mechanisms that mediate the synthesis of biological NPs should be studied in detail to
increase the rate of synthesis and improve the properties of NPs.
Protein–Nanoparticles Interactions
Authors: Naghib Seyed Morteza , Reza Garshasbi Hamid
Published: October 2023

Large surface area, small size, strong optical properties, controllable
structural features, variety of bioconjugation chemistries, and biocompatibility make
many different types of nanoparticles (NPs), such as gold NPs, useful for many
biological applications, such as biosensing, cellular imaging, disease diagnostics, drug
delivery, and therapeutics. Recently, interactions between proteins and NPs have been
extensively studied to understand, control, and utilize the interactions involved in
biomedical applications of NPs and several biological processes, such as protein
aggregation, for many diseases, including Alzheimer's. These studies also offer
fundamental knowledge on changes in protein structure, protein aggregation
mechanisms, and ways to unravel the roles and fates of NPs within the human body.
Advancing Fault Diagnosis for Parallel Misalignment Detection in Induction Motors Based on Convolutional Neural Networks
Authors: Rahmawan Hanif Adi , Widjianto Bambang Lelono , Indrawati Katherine , Ariefianto Rizki Mendung
Published: October 2023

Maintenance of machines is highly necessary to prolong the operational lifespan of induction motors. Prioritizing preventive measures is crucial in order to prevent more significant damage to the machinery. One of these measures includes detecting abnormalities, such as misalignment, in the motor shaft. This research is aimed to detect the misalignment of induction motor experimentally by varying the coupling between normal and parallel misalignment. The signal readings were analyzed in the frequency domain using Fast Fourier Transform (FFT). The results revealed that in the case of coupling misalignment, a peak appeared at f = 13.5 Hz, whereas in the parallel misalignment condition with a 1 cm misalignment, a peak was found at f+fr = 20 Hz. By utilizing the Convolutional Neural Network (CNN) system, normal and parallel conditions can be detected with an accuracy level of 87.5%.
O folclorismo e a melodia na 1.ª Suite Alentejana (1919) de Luís de Freitas Branco
Authors: Matos Vitor , Maia Pedro , Fonte Vera
Published: October 2023

Obra distinta e particular na produção de Luiz de Freitas Branco (1890–1955), a 1.ª Suite Alentejana (1919) apresenta-se conotada com uma vertente menos usual da linguagem do compositor – a evocação de elementos folclorizantes da sua região de eleição, o Alentejo. Praticamente um aparte na sua criação musical, a Suite espelha assim uma versatilidade na sua dimensão estética, revelando concomitantemente um lado tão universalista como racional – alguém que se socorre dos meios necessários para atingir um determinado fim. Apesar de vários autores reconhecerem a vertente folclorista na 1.ª Suite Alentejana, este aspeto ainda está por explorar de forma mais aprofundada, partindo de um estudo mais detalhado da escrita musical adotada por Freitas Branco. Com este artigo pretendemos propor uma análise da partitura focada nos diferentes tipos de melodias e texturas utilizadas, de forma a identificar e compreender melhor de que modo o autor incorpora elementos de cariz folclórico no discurso musical da obra.

Authors: Barros Anabela Leal
Published: October 2023

Daremos conta, neste trabalho, do projeto de edição da correspondência de/para Eurico Thomaz de Lima que faz parte do espólio oferecido à Universidade do Minho. O projeto, iniciado com a fotografia das cerca de quatrocentas unidades codicológicas epistolares, tem prosseguido ao longo dos últimos quatro anos com a edição de toda a correspondência e sua reorganização, por vezes complexa, incluindo a busca de nexo entre unidades dispersas e a procura de outras extraviadas. Neste artigo fazemos o inventário da correspondência editada (em lição semidiplomática, de forma a respeitar todo o seu conteúdo e ortografia, mas oferecendo-a suficientemente à leitura) e o elenco dos numerosos correspondentes, pela voz dos quais nos chegam firmes e unânimes testemunhos do seu génio, do seu notável percurso musical, profissional, mas também familiar, existencial; debruçar-nos-emos sobre algumas particularidades da orientação parental no início da sua carreira, conforme as cartas no-la deixam conhecer, dando ainda a ver o subido conceito que da sua pessoa, trabalho docente, de direcção escolar, composição e execução faziam os seus pares, bem como outras individualidades do panorama musical, literário, artístico e cultural, em especial de Portugal e do Brasil. Estes testemunhos são, em muitos casos, belas peças poéticas e filosóficas a merecer conhecimento pelo leitor contemporâneo.
High flyers: What sets them apart? A study of personality and reasoning in 800 senior managers
Authors: Jensen Troy M.
Published: October 2023

This study explores the relationship between personality factors, reasoning abilities and the speed at which individuals moved into senior management positions in organizations. The sample consists of 800 senior managers. The sample was separated into two groups based upon the amount of time it took the individuals to attain a senior manager role. Psychometric data from the two groups was then compared using independent samples t-tests and chi-square analyses. The results show that ‘high flyers’ are elevated on many indicators of effective social functioning, as well as on breadth and creativity of thinking. Further inquiry will be beneficial for more accurately identifying ‘high potential’ employees, as well as for building a business case for the importance of ‘soft skills’ development in organizations.

Evaluation of a Leadership Development Programme in a London Local Authority
Authors: Agabu Chika Grace
Published: October 2023

This is an evaluation of a Leadership Development Programme (LDP) consisting of a number of development approaches such as leadership coaching and action learning; carried out for leaders in a London Local Authority. Using semi-structured interviews and a focus group discussion the Taxonomy of Training and Development Outcomes (TOTADO) framework is applied to evaluate the influence of the LDP on individual, team and organizational level outcomes. Characteristics of coaching and action learning were examined; along with factors that may influence learning and transfer of learning to the workplace. Findings suggest that the LDP led to increased confidence and awareness of leadership behaviours and improved teamwork amongst leaders. Coaching content, the coach’s experience and experience sharing in action learning were found to promote leadership development. Manager and peer support, opportunity and work demands were found to influence transfer of learning to the workplace.
Reviewing psychological facets of workplace innovation
Authors: Costantini Arianna , Sartori Riccardo , Ceschi Andrea
Published: October 2023

In this article, we present a review of recent studies on workplace innovation (WPI) from a work and organizational psychology (WOP) perspective, with the aim of showing the potential advantages of taking a WOP perspective on WPI. We first outline a few different conceptualisations of WPI and of its main outcomes, that is, quality of working life and organizational performance. Next, we examine the intersections between research in WOP and WPI, specifically focusing on how an understanding of organizational and work-related dynamics can influence the effectiveness of WPI practices. Third, in an attempt to facilitate the integration of research on WOP and WPI and to disentangle the mechanisms underlying the effective implementation of WPI policies, we present evidence on three critical concepts in WOP and their relationship to WPI: job autonomy, job flexibility and participation in organizational life. Finally, we discuss some practical implications for Work and Organizational Psychologists interested in WPI implementation.
Creating the bottom-up organization from the top: Leaders as enablers of workplace innovation
Authors: Totterdill Peter , Exton Rosemary
Published: October 2023

Workplace innovation enhances economic performance and quality of working life simultaneously. Yet successive surveys show that its adoption rate is slow. In many European countries, there is little infrastructure to support the adoption of workplace innovation, often despite a long history of poor productivity and skills utilisation. Enterprise leadership therefore plays a critical role in determining whether or not workplace innovation practices are adopted. Three selected case studies illustrate journeys towards workplace innovation from different starting points. They demonstrate how a consistent approach to shared and distributed leadership can stimulate employee empowerment and initiative from the bottom up, as well as the cumulative impact of small incremental changes.
The roles conscientiousness and communication play in organizational commitment to change
Authors: Sai Linna
Published: October 2023

This study aims to examine the effect of conscientiousness on Organizational Commitment to Change (OCC) and the impact of formal and informal communication on OCC. Two hundred and four employees from a financial institution completed on-line questionnaires measuring personality, OCC (Affective, Normative & Continuance), and communication (formal & informal). The study evidences a negative relationship between conscientiousness and Continuance Commitment to Change (CCC). It reveals formal communication is a stronger predictor of OCC compared to informal communication. The study is also interested in how communication methods affect the relationship between conscientiousness and OCC. The findings of this study inform management to give due consideration to both formal communication and individuals’ levels of conscientiousness when planning and implementing organizational change.

Authors: van Doorn Robert R. A. , Kok Gerjo , Ruiter Robert A. C.
Published: October 2023

Workplace innovation (WPI) aims to strengthen both an organization’s performance and the employees’ quality of work life by improving the work environment in an organization. This contribution proposes the intervention mapping (IM) protocol to develop, implement, and evaluate and sustain WPI in an organization. IM combines person-centred and ecological (multilevel) views to involve individuals who function on diverse levels within an organization. The protocol applies theory-based change strategies to establish concrete and effective individual and environmental changes that are tailored to the local context of the organization.
Conceptualization of community-based entrepreneurship: A case study of Ecofiltro in Guatemala
Authors: Figueredo Alvaro , Chowdhury Rashedur
Published: October 2023

Workplace innovation and community-based entrepreneurship (CBE) constitute a powerful combination which, if leveraged, could potentially solve society’s most pressing problems. This case study illustrates how an entrepreneur, Philip Wilson combined these two elements to pursue the ambitious goal of taking clean water to one million families in Guatemalan rural areas by 2020, through his organization, Ecofiltro. The research was conducted between 2014 and 2015 in three rural Guatemalan communities. Historical data, observations and semi-structured interviews with Ecofiltro representatives, community leaders and customers were used as data collection methods for this exploratory study. The main objective was to gain a deeper understanding of what made the firm successful in achieving its ambitious goal, whereas other enterprises, mainstream non-government organizations (NGOs) and government institutions fail in solving social, health-related and economic problems. Findings reveal an ingenious workplace innovation led by a visionary leader and a way of organizing which extends Ecofiltro’s workforce by drawing from the local community; a simple yet powerful water filter which fits with the local culture.
Mapping and assessing psychosocial risk factors for individual- and organizational-level occupational stress intervention
Authors: Teichmann Mare
Published: October 2023

Various international organizations have raised awareness regarding psychosocial risks and work-related stress. From January 1, 2019, an amendment to the Estonian Occupational Health and Safety Act came into force, obliging the employer to ta ke measures to improve the psychosocial environment of the company in order to prevent health damage caused by psychosocial hazards. In current paper the focus is on: a) developing a mapping tool for psychosocial risk factors at work (Organizational Psychosocial Factors Indicator, OPSTI); b) delivering automatic feedback for the OPSTI test taker; c) evaluating workplace psychosocial risks at work by developing an organizational level psychosocial risk assessment system compliant with the requirements of European Agency for Safety and Health at Work (EU-OSHA); and d) developing different occupational stress interventions.
He, She or They – Does it matter in the workplace?
Authors: Donders Mila
Published: October 2023

This study examines non-binary people’s experience in the workplace with a special focus on the way they experience leadership. Five participants were interviewed and confronted with a hypothetical scenario in which they had to decide whether or not they would take a leadership position. The findings suggest that the non-binary gender identity and colleagues’ attitude towards it affected their decision and in some cases would cause the participants to decline the leadership position. Difficulties navigating the workplace as a non-binary person are also discussed. It is concluded that having a non-binary gender identity complicates not only work life, but most of a person’s daily life. However, more research is needed in order to clearly distinguish what the most pressing issues are.
The digital transformation of work is here – how scientists and practitioners can work together to manage needed workplace changes
Authors: Roth Colin
Published: October 2023

Organizations across Europe are reinventing their structures and processes in the quest to become more “agile”. To facilitate these changes methods like “Design thinking”, “Bar Camps” or “Working out loud” are becoming mainstream, no longer only used in hip start-ups and communication agencies. Traditional working environments, typically associated with rules, routines, and regulations are now transformed into open (co-working) spaces. Something big is going on and we wanted to find out about it by holding an interactive discussion. In this panel discussion we invited scientists and practitioners to engage in a conversation about future directions of Work and Organizational Psychology (WOP) with the aim of keeping education, research and practice relevant to contemporary working practices. We want to look into the current state of co-operation and cocreation within WOP and examine what needs to change and how this will be achieved. Together, we would like to figure out how research can support practitioners in their work with organizations and how to manage the digital transformation. As part of the scientist – practitioner collaborative stream (that has become known as Co-op Friday) this panel discussion compliments the conference theme of Working for the Greater Good by looking into future directions of organizational development and how to use evidence-based practices to help individuals to adapt to change. The aim of the session was to have an active debate between panelists and the audience generating ideas and activities to improve co-operation. We used an innovative process method called “Bar Camp” to encourage presentation and review. This resulted in interactive discussions with panel members and participants working in small groups (see Figure 1) discussing particular issues (see further detail in the following report). Each discussion session was followed by a brief summary that was shared across the groups.
Measuring broad self-regulatory skills in multi-locational knowledge work
Authors: Sjöblom Kirsi , Hietajärvi Lauri , Salmela-Aro Katariina
Published: October 2023

Due to the growing proportion of knowledge work and the work taking place in complex digital, physical and social surroundings employees are facing increasing demands to manage their own work and the psychological resources available to them. This study firstly presents the scientific background for why these skills, also called 21st century skills, are required by current working life, and secondly the process of developing and piloting a new questionnaire instrument to measure individuals’ broad self-regulation in knowledge work. Our questionnaire (N=202) measured behavioural self-regulation, cognitive-emotional self-regulation, and self-regulation of recovery. We used confirmatory factor analysis to specify and test the structure of the scale, and independent samples t-test and MANOVA to examine the differences between subgroups. The initial three-factor model showed a good fit. Latent variable correlation analyses indicated expected relations between self-regulation factors and established scales of well-being at work (work engagement, burnout). These results imply that this scale is suitable for measuring the self-regulatory skills of knowledge workers. This study underlines the importance of broad self-regulatory skills in supporting productivity and well-being in contemporary knowledge work. It operationalises the topical questions of how to assess and support proactive employee functioning in today’s increasingly complex physical, digital and social surroundings.
Becoming a professional: The five pillars of identification in Occupational Psychology in the UK
Authors: Elsey Vicki , Thompson Neill , Sillence Elizabeth , Longstaff Laura , Moss Mark
Published: October 2023

This study aims to explore how professional identification occurs in Occupational Psychology (OP) in the UK. Professional identification is a sense of belonging and individual feelings towards a group. In OP, competition for jobs is high and availability of roles with the title of “Occupational Psychologist” is low. Thus, many OPs are self-employed and multiple terms are used to describe the profession. Twenty working individuals, with a BPS accredited entry-level and master’s qualification in OP, participated in narrative interviews. Thematic analysis led to the development of five ‘pillars’ of professional identification: a) education and learning; b) networking; c) managing challenges; d) career-crafting; and e) professional recognition and authenticity. Each of the five pillars have a unique role to play in supporting professional identification in OP. Strong professional identification requires sustained effort in all pillars. Practitioners supporting the careers of Occupational Psychologists, and Occupational Psychologists themselves must develop stronger opportunities for networking and relationship building to enable individual development through multiple and diverse experiences. Furthermore, routes to accredited professional practice must be diversified and a positive rhetoric constructed around the achievement of Chartered status. Suggestions for future research are presented providing clear actions for the practitioner community.
Feedback intervention perceptions: Development and validation of a measure
Authors: Young Brandon L. , Fritzsche Barbara A.
Published: October 2023

Reactions toward performance feedback have critical implications for organizations and are of great interest to practitioners. Current measurement of employee experiences with feedback intervention varies widely and the literature is flooded with untested, coarse measures that largely neglect the complexity of feedback intervention. A new scale was developed to evaluate the characteristics of five feedback intervention components (i.e., performance measurement, feedback content, feedback delivery, organizational system support, and feedback source). Confirmatory factor analysis supports a five-factor structure. Correlational analyses demonstrate strong, differential relationships with feedback reaction measures and job satisfaction. Regression analyses demonstrate direct effects on motivation and intent to use feedback, and organizational justice mediates the relationships. Results indicate that the measure has good psychometric properties and support the utility of the Feedback Intervention Perceptions Scale for both research and practice. The FIPS provides practitioners with an evidence-based tool for holistically auditing and diagnosing deficiencies in organizational feedback interventions. A short form of the FIPS and preliminary validity evidence is also presented.
Methodological, ethical and legal problems of measuring and counteracting workplace mobbing
Authors: Durniat Katarzyna D.
Published: October 2023

The paper looks at theoretical and methodological problems, as well as legal and ethical issues, connected with diagnosing and counteracting workplace mobbing. Firstly, the author briefly presents the mobbing research tradition and points to current international approaches to and methods of measuring mobbing in the workplace. The author comments on the possibilities and limitations of the implementation of some methods, which are commonly employed in mobbing research and shares some doubts about the universality and international usage of the “mobbing/bullying tools”, which were developed under specific socio-organizational circumstances. Then, the paper discusses the legalities and practicalities of preventing and fighting mobbing in the context of Polish and European legislation. The author points to a wide spectrum of ethical and legal aspects of counteracting and dealing with mobbing. In conclusion, the author recommends that corporations and businesses should take all possible preventive steps to minimise the risk of mobbing, given that, apart from adversely affecting employees’ health, career, work engagement and job satisfaction, it substantially damages their reputation.
Participation in career development communities of practice: Perspectives from low socio-economic background students
Authors: Trottier Michelle
Published: October 2023

Despite experiencing challenges in transitioning into graduate employment (Ashley, Duberley, Sommerlad & Scholarios, 2015; Boston Consulting Group, 2017) low socioeconomic background students are less likely to engage with support offered through their higher education careers services (Greenbank & Hepworth, 2008; Simpson & Ferguson, 2013). This study investigates the efficacy of using a four-week online community of practice intervention aiming to build careers support engagement of students from low socio-economic backgrounds through peer learning. Through a series of 24 semi-structured interviews, it was found that students who disengaged from the intervention reported doing so due to feeling apprehensive about their lack of knowledge and experience, other commitments (especially term-time work and academic studies), and anxiety associated with transition from university to work. This research expands the careers counselling literature to not only consider career consulting practices, but also student engagement through leveraging social learning. This work has additional practical applications for careers practitioners highlighting benefits and drawbacks of offering career support through online communities of practice.

A picture is worth a thousand words: Pictorial scales for the assessment of work intensity
Authors: Soucek Roman , Voss Amanda S.
Published: October 2023

In the field of work and organizational psychology, verbal questionnaires provide a solid and valid foundation for the assessment of working conditions and employees’ attitudes. In the view of practitioners, these instruments are often too long, requiring a lot of time to complete, and employees might resist the invitation to participate in frequent surveys. To address these drawbacks, we present an alternative approach and describe the development of pictorial scales for the assessment of work intensity. Pictorial scales provide a simple and inviting format for the assessment of work intensity, and therefore, are a suitable instrument for practice-oriented formats such as interviews or workshops. Moreover, pictorial scales have advantages in repeated assessments such as in diary studies.

Published: October 2023

Background

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is a leading cause of mortality and morbidity. Patient knowledge about AF and its management is paramount but often limited. Patients need to be appropriately informed about treatment options, medicinal adherence, and potential consequences of nonadherence, while also understanding treatment goals and expectations from it. Mobile health apps have experienced an explosion both in their availability and acceptance as “soft interventions” for patient engagement and education; however, the prolific nature of such solutions revealed a gap in the evidence base regarding their efficacy and impact. Virtual patients (VPs), interactive computer simulations, have been used as learning activities in modern health care education. VPs demonstrably improved cognitive and behavioral skills; hence, they have been effectively implemented across undergraduate and postgraduate curricula. However, their application in patient education has been rather limited so far.

Objective

This work aims to implement and evaluate the efficacy of a mobile-deployed VP regimen for the education and engagement of patients with AF on crucial topics regarding their condition. A mobile VP app is being developed with the goal of each VP being a simple scenario with a set goal and very specific messages and will be subsequently attempted and evaluated.

Methods

A mobile VP player app is being developed so as to be used for the design of 3 educational scenarios for AF management. A pseudorandomized controlled trial for the efficacy of VPs is planned to be executed at 3 sites in Greece, Ukraine, and Kazakhstan for patients with AF. The Welch t test will be used to demonstrate the performance of patients’ evaluation of the VP experience.

Results

Our study is at the development stage. A preliminary study regarding the system’s development and feasibility was initiated in December 2022. The results of our study are expected to be available in 2024 or when the needed sample size is achieved.

Conclusions

This study aims to evaluate and demonstrate the first significant evidence for the value of VP resources in outreach and training endeavors for empowering and patients with AF and fostering healthy habits among them.

Potential Schizophrenia Disease-Related Genes Prediction Using Metagraph Representations Based on a Protein-Protein Interaction Keyword Network: Framework Development and Validation
Authors: Yu Shirui , Wang Ziyang , Nan Jiale , Li Aihua , Yang Xuemei , Tang Xiaoli
Published: October 2023

Background

Schizophrenia is a serious mental disease. With increased research funding for this disease, schizophrenia has become one of the key areas of focus in the medical field. Searching for associations between diseases and genes is an effective approach to study complex diseases, which may enhance research on schizophrenia pathology and lead to the identification of new treatment targets.

Objective

The aim of this study was to identify potential schizophrenia risk genes by employing machine learning methods to extract topological characteristics of proteins and their functional roles in a protein-protein interaction (PPI)-keywords (PPIK) network and understand the complex disease–causing property. Consequently, a PPIK-based metagraph representation approach is proposed.

Methods

To enrich the PPI network, we integrated keywords describing protein properties and constructed a PPIK network. We extracted features that describe the topology of this network through metagraphs. We further transformed these metagraphs into vectors and represented proteins with a series of vectors. We then trained and optimized our model using random forest (RF), extreme gradient boosting, light gradient boosting machine, and logistic regression models.

Results

Comprehensive experiments demonstrated the good performance of our proposed method with an area under the receiver operating characteristic curve (AUC) value between 0.72 and 0.76. Our model also outperformed baseline methods for overall disease protein prediction, including the random walk with restart, average commute time, and Katz models. Compared with the PPI network constructed from the baseline models, complementation of keywords in the PPIK network improved the performance (AUC) by 0.08 on average, and the metagraph-based method improved the AUC by 0.30 on average compared with that of the baseline methods. According to the comprehensive performance of the four models, RF was selected as the best model for disease protein prediction, with precision, recall, F1-score, and AUC values of 0.76, 0.73, 0.72, and 0.76, respectively. We transformed these proteins to their encoding gene IDs and identified the top 20 genes as the most probable schizophrenia-risk genes, including the EYA3, CNTN4, HSPA8, LRRK2, and AFP genes. We further validated these outcomes against metagraph features and evidence from the literature, performed a features analysis, and exploited evidence from the literature to interpret the correlation between the predicted genes and diseases.

Conclusions

The metagraph representation based on the PPIK network framework was found to be effective for potential schizophrenia risk genes identification. The results are quite reliable as evidence can be found in the literature to support our prediction. Our approach can provide more biological insights into the pathogenesis of schizophrenia.

UNSTRUCTURED

Cancer prevalence data for Black Americans is monolithic and fails to consider the diverse cultures and backgrounds within that community. For instance, African immigrants constitute a meaningful proportion of the foreign-born Black immigrants in the United States (42%), but the prevalence of cancer in the African immigrant community itself is unknown. Therefore, without accurate cancer prevalence data, it is impossible to identify trends and other key factors that are needed to support the health of African immigrants and their children. Moreover, it is impossible to understand how the culture and language of subgroups influence their cancer-related health behavior. While research in this area is limited, the existing literature articulates the need for culturally responsive and culturally tailored cancer education for African immigrants and their adolescent children, which is what we advocate for in this viewpoint paper. Existing projects demonstrate the feasibility of culturally responsive programming for adults; however, few projects include or focus on adolescents or children born to African immigrants. To best meet the needs of this understudied community, researchers must use culturally competent interventions alongside familiar, usable media. For adolescents, technology is ubiquitous thus, the creation of a culturally tailored digital intervention has immense potential to improve cancer awareness and prevention for youth and their community. More research is needed to address many of the existing research gaps and develop a rich understanding of the unique experience of cancer among African immigrant families that can be used to inform intervention development. Through this viewpoint, we review the current state of cancer-related research among African immigrant families in the United States. In this paper, we acknowledge the current knowledge gaps and issues surrounding measurement and then discuss the factors relevant to designing an educational intervention targeted at African immigrants and the role of African immigrant youth.

Создание материалов, представляющее собой черные покрытия, работающие в ближнем и среднем ИК-диапазонах, является актуальной задачей. Слои таких материалов могут использоваться для улучшения эффективности ИК-излучателей. Одним из перспективных материалов, хорошо согласующимся с МЭМС технологией, является покрытие из черного оксида алюминия. В данной работе представлены результаты формирования слоя черного оксида алюминия методом вакуум-термического испарения, и исследования его поглощающих свойств в ИК-области спектра. Экспериментальные образцы слоев черного оксида алюминия продемонстрировали поглощение в диапазоне от 2,2 до 28 мкм на уровне 84% и показали высокую температурную стабильность до 800 °C.
A COMPARATIVE STUDY OF STUDENT TEACHERS’ EXPERIENCES WITH COLLABORATING TEACHERS IN THE CZECH REPUBLIC AND THE UNITED STATES
Authors: Devereaux Michelle , Orlova Natalia
Published: October 2023

Within a teacher education programs, student teachers must participate in a teaching practicum, when teachers-in-training (i.e., pre-service teachers) work with experienced teachers (i.e., in-service teachers) in their classrooms, learning the best practices related to pedagogy. This context, the student teaching practicum, has been studied extensively in a wide range of publications. However, comparative studies across countries that examine the experiences and perspectives of the practicum participants have not been deeply explored in the literature. The following study seeks to understand how student teachers in the Czech Republic and the United States perceive their practicum and the role of their collaborating teacher. Building on previous research that focuses on the effective traits of collaborating teachers and the effective types of feedback collaborating teachers give, this study compares student teachers’ experiences with their collaborating teachers and seeks to understand the differences between the two. The findings lead to topics in comparative education which could be explored in greater depth.
IMPLEMENTING DISCIPLINE-SPECIFIC WRITING SUPPORT FOR UNDERGRADUATE STUDENTS IN THE OMANI CONTEXT
Authors: Mathew Priya , Sankara Narayanan Radhika
Published: October 2023

This paper evaluates how a writing centre in a private higher education institution in Oman supports discipline-specific academic writing for undergraduate students in Computing, Business, and Electronics Civil and Mechanical Engineering. One of the key interventions introduced by the centre was adopting a writing in the disciplines (WID) approach by offering scheduled writing classes for selected modules in these disciplines and incorporating genre-based pedagogy in final-year capstone projects. The embedded sessions were designed to support 550 students enrolled in seven modules across the three disciplines in meeting their coursework requirements. Integrating this intervention into the curriculum involved close collaboration with subject teachers to understand the assigned genres, designing relevant course materials for synchronous and asynchronous learning, and implementing innovative and research-informed pedagogies. Students were also offered individual consultations to complement the support offered during the classroom sessions. This study attempts to evaluate the effectiveness of these embedded modules and the genre-based pedagogy approach for the capstone projects undertaken by final-year students. Feedback was collected from students, as well as the faculty members involved, through the institutional module evaluation surveys and feedback forms. The findings indicate that there is significant improvement in the quality of assignments of those students who availed the services of the center. Although the interventions are specific to these programmes and contexts, they may provide a model for other writing and language centres to develop innovative pedagogical models to support disciplinary student writing at both undergraduate and postgraduate levels.
