Reaction coordinate diagrams (RCDs) are chemical representations widely employed to visualize the thermodynamic and kinetic parameters associated with reactions. Previous research has demonstrated a host of misconceptions students adopt when interpreting the perceived information encoded in RCDs. This qualitative research study explores how general chemistry students interpret points and trends on a RCD and how these interpretations impact their inferences regarding the rate of a chemical reaction. Sixteen students participated in semi-structured interviews in which participants were asked to interpret the points and trends along provided RCDs and to compare relative reaction rates between RCDs. Findings derived from this study demonstrate the diversity of graphical reasoning adopted by students, the impact of students’ interpretations of the x-axis of a RCD on the graphical reasoning employed, and the influence of these ideas on inferences made about reaction rate. Informed by analytical frameworks grounded in the resources framework and the actor-oriented model of transfer, implications for instruction are provided with suggestions for how RCDs may be presented to assist students in recognizing the critical information encoded in these diagrams.

Abstract Background Homeopathy has been experiencing a period of expansion in Brazil due to its practical relevance in the face of new global and national health demands, culminating in the launch in 2006 of the National Policy for Integrative and Complementary Practices (NPICP) by the Ministry of Health of Brazil, which standardized and regularized the position of homeopathy within the Brazilian Unified Health System (SUS). Aims To understand the impact of the guidelines proposed by the NPICP on homeopathy services in the SUS, specifically in the south-east region of Brazil, according to the perceptions of their managers. Methods This is a descriptive, exploratory research study with a qualitative approach, conducted in homeopathy services in the south-east region of Brazil, through semi-structured interviews and with data processed using content analysis. Results The data show the importance of the NPICP in regulating and offering homeopathy in the services studied. However, the NPICP's objective of promoting and fully developing integrative and complementary practices has not been achieved because it has failed to translate strategies into actions. Conclusions Though important to the development of homeopathy services in any given location, policies stated in the NPICP were revealed to have limited impact on the implementation and development of new services. Without further legislation, training programs and appropriate budget allocation, new services will be unable to thrive and their users unable to benefit from a more comprehensive approach to healthcare.

The objective of this study was to explore and describe the factors that influence the decision by pregnant women to be tested for HIV. This was achieved through a qualitative research study that was exploratory, descriptive and contextual in nature. A sample of 13 pregnant women participated. Data obtained from semi-structured interviews was analysed according to a protocol based on a combination of methods of analysis. The three main themes, namely factors that contribute to the decision by pregnant women to be tested for HIV, factors that contribute to the decision by pregnant women not to be tested for HIV and organisational factors that influence the decision by pregnant women to be tested for HIV, were divided into nine subthemes. Conclusions and recommendations to promote counselling to pregnant women being tested for HIV are provided. Opsomming Die doel van die studie was om die faktore wat die besluit van swanger vroue om vir MIV getoets te word, te verken en beskryf. Dit is gedoen deur middel van verkennende, beskrywende, kontekstuele kwalitatiewe navorsing. ’n Steekproef van 13 swanger vroue het deelgeneem. Inligting is verkry deur middel van semi-gestruktureerde onderhoude. Hierdie inligting is ontleed aan die hand van ’n protokol gebaseer op ’n kombinasie van ontledingsmetodes. Die drie hooftemas, naamlik faktore wat bydra tot swanger vroue se besluit om vir MIV getoets te word, faktore wat bydra tot swanger vroue se besluit om nie vir MIV getoets te word nie en organisatoriese faktore wat swanger vroue se besluit beïnvloed om vir MIV getoets te word, is in nege subtemas onderverdeel. Gevolgtrekkings en aanbevelings ter bevordering van berading van swanger vroue vir MIV-toetsing, word verskaf.

Abstract The aim was to know and analyze the meanings of intrafamily sexual violence experienced and the Court support for adolescents who underwent the questioning. A qualitative research study through semi-structured interviews and free observation with nine adolescents aged between 13 and 17 years old, in a specific Court of Childhood and Youth. Data was analyzed using the technique of content analysis, with “Distance and negative”, and “Secondary victimization” pointed out. First, by signifying the intrafamily sexual violence suffered, the adolescent presents memory lapses about what happened, and it shows a wide spectrum of detrimental effects of intrafamily sexual violence. Secondly, it shows that the intervention of the Judiciary Branch has caused secondary victimization, gaps in care, and reproduction of power relationships. It was concluded on the importance to articulate a children and adolescents rights guaranteeing system, considering the new social frameworks, as well as the issue of human development.

The purpose of this study was to elucidate and describe students’ thinking when making connections between substitution and elimination reactions and their corresponding reaction coordinate diagrams. Thirty-six students enrolled in organic chemistry II participated in individual, semi-structured interviews. Three major themes were identified that characterize students’ difficulties with integrating the information from the reactions and the reaction coordinate diagrams: incorrect ideas about the meanings of the reaction coordinate diagrams’ features, errors when examining reaction mechanisms, and an inability to assess the relative energies of reaction species. These findings suggest that students need support for coherence formation between reactions and reaction coordinate diagrams. Implications for teaching to address these student difficulties are suggested.

The teaching personal and social responsibility (TPSR) model has been extensively used in a vast array of settings. However, few TPSR studies have focused on preschool settings. The purpose of this action research study was to analyze the experiences of a program leader, her preschool children, and their parents throughout a TPSR program focused on transference of responsibility model goals. The participants were 25 preschool children, six parents, and a program leader involved in a preschool setting located in the north of Portugal. Data were collected through reflexive journaling, participant observations, semi-structured interviews, and focus group interviews. Findings suggest the TPSR model could be a useful instructional model for preschool teachers focused on providing social and emotional learning opportunities to their students. In order to foster transference, parents played a pivotal role in this process and were included in the intervention, which appeared to enhance life skill transfer.

A qualitative research study was conducted to explore the occupational needs and interests of young men, aged 18–30 years, who had been diagnosed with schizophrenia. Four men participated in two focus groups and described their daily occupations, both before and after diagnosis. The constant comparative method of data analysis was used to generate the categories inductively, yielding several common themes and stories. A shared narrative was subsequently identified, which best reflected the collective lost dreams, disruptions and losses resulting from a diagnosis of schizophrenia. The chapters of the participants' narrative describe a common struggle of attempting to rebuild lives in spite of persistent perceived barriers. The research sheds light upon the use of occupation in assisting young men to reclaim lost dreams and lives, as well as upon the impact of diagnosis on occupational engagement.

Purpose – The purpose of this paper is to examine how small- and medium-sized organisations that were already participating in recognised sustainability programmes in Iowa, USA, in how they were utilising activities normally associated with human resources (HRs) to implement sustainability – activities included communication, engagement, incentives and recruitment and retention. Design/methodology/approach – The authors were interested in how small- and medium-sized enterprises (SMEs) were utilising HR functions to implement sustainability. This was an exploratory, qualitative research study utilised semi-structured interviews to obtain data. Findings – Based on the findings, some of the functions are being utilised more than others, with some activities not being implemented at all. Research limitations/implications – This research offers empirical research on how sustainability is achieved in SMEs. Practical implications – This paper outlines some practical methods that any SME could utilise to help implement sustainability within an organisation. Originality/value – This paper adds empirical research on how SMEs are implementing sustainable practices into their operations by using activities normally associated with the HR department.
