The aim of this study was to determine students’ understanding of fundamental AC signal concepts, such as frequency, amplitude, and phase difference. The participants in the study were 179 students (44 female and 135 male) attending Izmir Vocational School who were enrolled in the Analog Electronics Course. The data of the study were collected by means of three open-ended questions and semi-structured interviews. In the questions, students were given a graph of an AC signal and asked to draw a signal with equal frequency but higher amplitude, a signal with equal amplitude but higher frequency, and a signal with a certain phase difference. The main aim of the interviews was to provide a deeper insight into the difficulties detected in the analysis of the questions. The data analysis showed that the students confused the concepts of frequency and amplitude and had difficulties in interpreting the signals that exhibited a phase difference.

Abstract This study aims to examine the use of English loanwords inflected with Arabic morphemes by young people in Amman, Jordan. It adopts a quantitative corpus-based approach supported by qualitative data. We collected data from young Facebook male and female users who come from families with different socio-economic status, and we conducted semi-structured interviews with 60 students at the University of Jordan to get more insight into the attitudes of young individuals in Jordan who use these English loanwords, and to account for the reasons that drive these individuals to use them. Data analysis shows that the participants’ gender and socioeconomic status are major factors that affect the use of these loanwords. Data analysis also reveals that these English loanwords could be used as a form of slang by a certain group of young individuals in Amman to claim a specific social identity and an in-group membership that distinguishes them from another group of young individuals who do not use these words. We argued that a number of symbolic values could be attached to the use of English loanwords inflected with Arabic morphemes by that group and analysed the reasons behind such linguistic behaviour.

The psychological environment where sporting activity is undertaken has been suggested to influence performance. The coach orchestrates practice activities and their perception of the psychological environment has been regularly evaluated in competition research but not in practice. The aim of this study was to explore coach perceptions of the psychological influencing factors present in the practice environment. Participants were six U.K. academy basketball coaches (mean age = 35 years). Data were collected through semi-structured interviews and analyzed using interpretative phenomenological analysis. Five superordinate themes were constructed from data analysis, which were player characteristics, team-first orientation, current performance perceptions, coach characteristics, and coaching structure. Results suggest that the coach has a unique insight into the psychological influencing factors of the practice environment. Combined with the practice environment framework offered by Smith, Cotterill, and Brown, a model is offered to aid practitioners in understanding the interrelatedness of psychological influencing factors in the practice environment.

Background: This article examines Implementing New Knowledge Environments’ (INKE) experiences as a mature, large-scale collaboration working with academic and non-academic partners and provides some insight into best practices. It looks at the sixth year of funded research.Analysis: The study uses semi-structured interviews with questions focused on the nature of collaboration with selected members of the INKE research team. Data analysis employs a grounded theory approach.Conclusion and implication: The interviewees found the experience of collaborating within INKE to be positive with some ongoing challenges. The team is winding down as it moves into the final year of funded research. This suggests an arc of collaboration, with intensity of collaboration building from the first year to the most intensive time in the middle years and then winding down in the last years of grant funding. This article contributes to those lessons about collaboration by exploring the lived experience of a long-term, large-scale research project.


Delirium is a common serious complication in dementia that is associated with poor prognosis and a high burden on caregivers and healthcare professionals. Appropriate care is therefore important at an early stage for patients with delirium superimposed on dementia To gain insight into the care of six patients with delirium superimposed on dementia, 19 semi-structured interviews were conducted focused on the experiences of caregivers and professionals. The interviews revealed four themes that appeared to play a role: 1. experiences with and views on behavioral problems of these patients, 2. recognition and diagnosis of delirium in dementia, 3. views on good care and 4. organizational aspects. Knowledge gaps about delirium in dementia, as well as ethical considerations, play an important role in organizing timely and adequate care for patients with delirium superimposed on dementia.

AbstractNowadays, big data is a widely utilized concept that has been spreading quickly in almost every domain. For pharmaceutical companies, using this concept is a challenging task because of the permanent pressure and business demands created through the legal requirements, research demands and standardization that have to be adopted. These legal and standards’ demands are associated with human healthcare safety and drug control that demands continuous and deep data analysis. Companies update their procedures to the particular laws, standards, market demands and regulations all the time by using contemporary information technology. This paper highlights some important aspects of the experience and change methodology used in one Macedonian pharmaceutical company, which has employed information technology solutions that successfully tackle legal and business pressures when dealing with a large amount of data. We used a holistic view and deliverables analysis methodology to gain top-down insights into the possibilities of big data analytics. Also, structured interviews with the company’s managers were used for information collection and proactive methodology with workshops was used in data integration toward the implementation of big data concepts. The paper emphasizes the information and knowledge used in this domain to improve awareness for the needs of big data analysis to achieve a competitive advantage. The main results are focused on systematizing the whole company’s data, information and knowledge and propose a solution that integrates big data to support managers’ decision-making processes.

Intimate partner violence (IPV) is a complex and multifaceted problem gaining increasing attention within mental health research and practice. IPV explanations focus on both individual and systemic levels; however, it is increasingly acknowledged that a single level explanation may not be sufficient. The practices of clinical disciplines may, however, still privilege an explanation at one level over another, which will influence how they work with clients. It is likely that one such clinical group, psychologists, may play a critical role in helping victim-survivors to understand and explain their experiences of IPV. However, we were unable to find any studies focusing on women’s perceptions of psychologists’ role in this. Additionally, we know little about women victim-survivors’ perceptions of why their partners use IPV. To address these gaps, the research question for this study was: What explanations resonate during counseling for women in understanding their partner’s abuse? To explore this question, 20 women who had seen psychologists after experiencing IPV participated in semi-structured interviews. The interviews were analyzed using reflexive thematic analysis and three themes constructed from the data. The first two themes, narcissist description was helpful and not all bad all the time, showed that the women found it powerful in their healing processes when psychologists offered the opportunity to discuss their partners individual characteristics as explanations for their use of IPV. The third theme, structural explanations, showed that some of the women also reflected on wider structural contexts. Implications for clinical practice include the potential healing effect when practitioners can move along a continuum of explanation levels, covering both the inner and outer worlds. Implications for research into IPV perpetration are that women hold expertise and insight into individual perpetrators and could make valuable contributions to this field.

Purpose – The purpose of this paper is to present the findings of research that aimed to determine what university students living in Unite accommodation in the UK understand about the concept of sustainable living. It considers what barriers they perceive to be standing in the way of following sustainable living practices. In particular, the research aimed to explore any value–action gap for the student population with a view to informing future actions to help close any gap. Design/methodology/approach – The study was completed through an online questionnaire survey of students living in halls of residence operated by provider The Unite Group Plc. The survey informed semi-structured interviews and focus groups that explored the issues raised in greater detail. Findings – It was found that students living in Unite properties believed sustainable living to be important, yet levels of understanding were very low and there appeared to be a wide value–action gap. Reasons for this are varied; however, an unexpected theme emerged around the association of effort and importance. There was a very strong association between sustainable living and recycling, which, therefore, saw the lack of adequate recycling facilities as a significant barrier to sustainable living. There were also issues around a lack of information, cost and respondents’ flatmates as further barriers. However, the most significant barrier was the displacement of responsibility for sustainable living to other people or organisations. Originality/value – Gaining an insight into the complexity of attitude and behaviour of students with the sustainability agenda will enable understanding that can be applied to activities that promote sustainability.

The purpose of this study was to explore the stress, emotion, and coping (SEC) experiences of elite cricketers leading up to and on the day of their first competitive fixture of the season. Four elite male cricketers (M = 21.25, SD = 1.5) completed Stress and Emotion Diaries (SEDs) for the 7-day period leading up to and on the day of their first competitive fixture of the season. We then interviewed the cricketers to explore the content of the SEDs in more detail. We used semistructured interviews to glean insight into the stressors, cognitions, emotions, coping strategies, and behaviors. Inductive and deductive content data analysis provided a holistic and temporal exploration of the SEC process underpinned by the cognitive-motivational-relational theory of emotions (Lazarus, 1999). The results highlighted the ongoing and continuous nature of the SEC process while illustrating the coping strategies the cricketers used leading up to and on the day of competition.

This study provides insight into the experiences of young adults born with variations of sex characteristics to identify aspects of care and social support that need improvement. Semi-structured interviews with intersex youths in Switzerland were analyzed using interpretative, phenomenological analysis. Young adults desire timely, patient-centered information about their diagnoses. Peer support is key to delivering high-quality care but rarely systematically implemented. Intersex youth often face misrepresentation, stigma, and discrimination in medical settings and in society. Increased visibility alone cannot tackle these issues, but a feminist curiosity of care will enable health providers and society to overcome preconceptions of body normativity.
