Wear of Ball Attachments After 1 to 8 Years of Clinical Use: A Qualitative Analysis

The purpose of this study was to analyze and compare scanning electron microscopy (SEM) observations of ball attachments that had been worn by patients during three periods of clinical use. One hundred forty-four specimens of ball anchor attachments (gold alloy matrix and titanium patrix) were studied by SEM after periods of approximately 1, 3.5, and 8 years of clinical use. Twenty new attachment components were examined as controls. SEM images revealed signs of mechanical wear for the ball attachments studied. The surfaces of the titanium patrix were associated primarily with roughening after short-term use, whereas surfaces of the gold alloy matrix showed wear, roughening, and loss of microscopic material in the form of flakes. Severe mechanical wear on both surfaces was noted after longer periods of use. The mechanical changes were not correlated with patient-mediated observations regarding the time-dependent retentive efficacy of the attachments. One year of clinical wear appeared to have limited effect on the ball attachment tested. Conversely, longer periods of use led to marked modifications in shape of the matrix and patrix components.

Qualitative analysis of the care of children in hospital in four countries : part 2

As part of a large study of the care of children in Australian, British, Indonesian, and Thai hospitals, qualitative methods were used to examine differences influenced by culture. Two groups were surveyed: parents of hospitalized children, and staff caring for them. Vignettes were used to invoke discussion, and content analysis was used to examine the data. Subjects were interviewed singly, or in focus groups. These interviews were audiotaped and transcribed for analysis. This article is the second of a two-part series, and includes results of the staff's interviews and discussion. The parents' results and discussion were published in Part 1 (Shields [amp ] King, 2001). Staff in all the countries considered communication with parents to be an important part of care of the hospitalized child, and this was consistent with the parents' responses. Staff were mindful of safe practices, though more so in Australia and Britain than Indonesia and Thailand. Cost of treatment for the parents was an important consideration for staff in Indonesia and Thailand when they were planning care for the child. Cultural constructions were more likely to be considered by the Australian and British staff than the Indonesian and Thai staff, and this may have been influenced by the prevailing culture of medical dominance in those countries.

Qualitative analysis of the care of children in hospital in four countries : part 1

As part of a large study of the care of children in Australian, British, Indonesian, and Thai hospitals, qualitative methods were used to examine differences influenced by culture. Two groups were surveyed: parents of hospitalized children, and staff caring for them. Vignettes were used to invoke discussion, and content analysis was used to examine the data. Subjects were interviewed singly, or in focus groups. These interviews were audiotaped and transcribed verbatim. The data were explored by using content analysis to extract themes of understanding of cultural experiences. This article is the first of a two-part series, and includes a review of the literature, description of the methods used, and results of the parents' interviews. The staff results and discussion will be published in Part 2. Analysis revealed that parents in all countries were primarily concerned with treating the child's illness and the child's recovery. Parents were concerned with their work (employment), but this was a much larger consideration in Indonesia and Thailand, where no social security systems exist, than in Australia and Britain. Communication with staff was the most commonly mentioned theme for parents, indicating that irrespective of the culture in which the care was given, good communication between parents and staff was of paramount importance.

Effect of hydrogen/air flow rates and scan rate on the flame ionisation detection response of phopholipids, and their quantitative and qualitative analysis by Iatroscan (Mark‐6s) TLC‐FID

The combined effect of scan speed, hydrogen and air flow rates on the flame ionization detection (FID) peak response of phospholipid classes has been studied to determine the optimum levels of these parameters. The phospholipid composition of different types of commercial lecithins, as well as lecithins combined with fish oils, has been analyzed by Iatroscan TLC‐FID Mark‐6s under optimized conditions. An air flow rate of 2 L/min, a hydrogen flow rate of 150–160 mL/min, and a scan speed of 30 s/rod seem to be the ideal conditions for scanning phospholipids with complete pyrolysis in the flame in the Mark‐6 model. Increasing the scan speed rapidly decreased the FID response. A hydrogen flow rate as high as 170 mL/min could be used at relatively low air flow rates (&#x003C2 L/min) and the response declined when both air flow rate and hydrogen flow rate increased simultaneously. Both linear and curvilinear relationships had highly significant correlations (p&#x003C0.01) with the sample load. Time course reactions, including the hydrolysis of phosphatidylserine using enzymes, can be successfully monitored by the Iatroscan TLC‐FID Chromarod system.

Challenges to infrastructure delivery during the economic downturn : a qualitative analysis

Infrastructure plays a key role in creating and maintaining sustainable economic growth and a prosperous community. Infrastructure projects generally require a large amount of capital investment, which motivates involvement from the private sector in the delivery process. The Global Financial Crisis placed enormous pressure on both the public and private sectors, as the ability to borrow money for an extended tenor was greatly reduced. This study adopts a qualitative approach to analyse the challenges facing the delivery of infrastructure projects in an Australian context by considering the impacts of the Global Financial Crisis. It is found that the availability of resources and finance are perceived as the biggest challenges, with resources being more of a concern than finance to interviewees. In addition to these findings, ways in which the private sector can be better involved in the infrastructure delivery is discussed.

The Pathways model of assault : a qualitative analysis of the assault offender and offence

Research on offending behavior rehabilitation suggests that offenders would gain the maximum benefit from programs that reflect the individual needs of different types of offender. Multivariate theories of offending behavior are thus required to inform individualized rehabilitation. The aim of the current study was to construct a multivariate model for the prolific offense of assault. Qualitative methodology was used to construct a descriptive model of assault for 25 adult assault offenders. The model incorporated the development of violent behavior, types of anger, violence motivation, and the assault offense. The model consisted of 14 categories, 10 of which allowed for individual differences in behavior. A total of 35 participant transcripts were then coded through the model where the individual differences occurred. Five main offense types were found. The characteristics of the types of assault offense gave indications for how rehabilitation may be targeted for each group.

A qualitative analysis of the Taiyi Jinhua Zongzhi

The Taiyi Jinhua Zongzhi (太一金華宗旨) is an important Daoist text, in particular to the Longmen branch of the Quanzhen movement. It is attributed to Lü Dongbin and describes a form of meditation called huiguang (回光 – turning around or reversing the light). The text was popularized in the West through a commentary by Carl Jung on Richard Wilhelm’s translation. However, the accuracy of both Jung’s commentary (e.g., Cott & Rock, 2009) and Wilhelm’s translation (e.g., Cleary, 1991) have been questioned. While the Taiyi Jinhua Zongzhi tends to express its message in much clearer language than many Daoist texts, it is still may not be immediately accessible to most readers on first viewing. Thus, the results presented herein are intended to clearly present the main messages of the Taiyi Jinhua Zongzhi for those unfamiliar with the text, while attempting to avoid committing the same errors as, for example, Jung. To do this, the present analysis extracted all the prominent constructs discussed in the text, descriptions of their nature, and the relationships between them. This resulted in five overarching themes, two of which describe the general process of turning the light around, and a further three that describe a stage-like progression resulting from this general process. The constructs and relationships that constitute each theme are discussed in detail with the aid of diagrammatic representations, as are the relationships between the five themes.
It is hoped that this analysis will make the general teachings of the Taiyi Jinhua Zongzhi more accessible to psychologists wishing to pursue studies in the area of Daoism.

Parent and child interactions with two contrasting anti-obesity advertising campaigns : a qualitative analysis

Social marketing has been proposed as a framework that may be effectively used to encourage behaviour change relating to obesity. Social advertising (or mass media campaigning) is the most commonly used social marketing strategy to address the issue of obesity. While social advertising has the potential to effectively communicate information about obesity, some argue that the current framing and delivery of these campaigns are ineffective, and may cause more harm than good.

The views of parents who experience intergenerational poverty on parenting and play: a qualitative analysis

BACKGROUND: There is minimal literature on how parents experiencing intergenerational poverty view their role as parents and the value they place on children's play. The objective of this study was to examine how these parents view their parenting role and their beliefs about children's play. METHODS: Thirteen mothers of preschool-aged children who experienced intergenerational poverty were recruited to the study. Semi-structured interviews were conducted and were analysed using interpretive phenomenological analysis. RESULTS: Parents described their role as guiding their children to become 'good' people, to teach them skills and provide a routine within the home. There were two disconnections in the data including the view that whilst parenting was hard and lonely, it was also a private matter and participants preferred not to seek support. A second disconnection was in terms of their beliefs about play. Parents believed that whilst play was valuable to their child's development, it was not their role to play with children. However, if parents did play with their child, they noticed positive changes in their child's behaviour. CONCLUSION: The views of parents who experienced intergenerational poverty were similar to other reported findings in parenting studies. However, the current sample differed on not seeking help for support as well as not seeing their role as playing with their children, even though occasions of joining their child in play were associated with a positive change in their relationship with their child. This has implications for communicating about parenting issues with parents who have experienced intergenerational poverty.

The impact on family functioning of social media use by depressed adolescents: a qualitative analysis of the family options study

BACKGROUND: Adolescent depression is a prevalent mental health problem, which can have a major impact on family cohesion. In such circumstances, excessive use of the Internet by adolescents may exacerbate family conflict and lack of cohesion. The current study aims to explore these patterns within an intervention study for depressed adolescents.

METHOD: The current study draws upon data collected from parents within the family options randomized controlled trial that examined family based interventions for adolescent depression (12-18 years old) in Melbourne, Australia (2012-2014). Inclusion in the trial required adolescents to meet diagnostic criteria for a major depressive disorder via the Structured Clinical Interview for DSM-IV Childhood Disorders. The transcripts of sessions were examined using qualitative thematic analysis. The transcribed sessions consisted of 56 h of recordings in total from 39 parents who took part in the interventions.

RESULTS: The thematic analysis explored parental perceptions of their adolescent's use of social media (SM) and access to Internet content, focusing on the possible relationship between adolescent Internet use and the adolescent's depressive disorder. Two overarching themes emerged as follows: the sense of loss of parental control over the family environment and parents' perceived inability to protect their adolescent from material encountered on the Internet and social interactions via SM.

CONCLUSION: Parents within the context of family based treatments felt that prolonged exposure to SM exposed their already vulnerable child to additional stressors and risks. The thematic analysis uncovered a sense of parental despair and lack of control, which is consistent with their perception of SM and the Internet as relentless and threatening to their parental authority and family cohesion.

Food waste in lower-middle income households: a qualitative analysis of antecedents and a typology of food wasters

Esta dissertação doutoral, com base em dados empíricos coletados com 50 mães distribuídas no Brasil (n = 30) e nos EUA (n = 20), tem como objetivo fornecer uma melhor compreensão do desperdício de alimento no contexto da baixa renda. A tese é composta por três artigos, que combinados, cumprem os objetivos de identificar os antecedentes do desperdício de alimento e delinear uma tipologia dos desperdiçadores de alimento. Adicionalmente, contextualiza o desperdício global e um capítulo propõe uma agenda futura para estudos sobre desperdício de alimento no âmbito do consumidor. O desperdício de alimento nas famílias, enquanto tema de pesquisa, oferece a oportunidade para o trabalho acadêmico em marketing cumprir os critérios de relevância social, gerencial e para políticas públicas. No primeiro estudo, descrevem-se os fatores do chamado "paradoxo do desperdício de alimento", a identificação e análise do desperdício de alimento em famílias com restrições orçamentárias, enquanto apresentam-se o itinerário do consumo de alimentos e os antecedentes do desperdício. Este primeiro artigo, elaborado com dados coletados em famílias brasileiras, ilustra também o papel das normas culturais, tais como o preparo abundante de alimento para mostrar hospitalidade ou como forma de não ser percebido como pobre, no aumento do desperdício. No segundo artigo, uma grounded-theory (teoria fundamentada nos dados) destaca o papel do afeto e da abundância no desperdício de alimento familiar. Para enriquecer as contribuições teóricas, este segundo estudo apresenta um framework com seis dimensões do desperdício de alimento (1. Afeto; 2. Abundância; 3. Multiplicidade de escolhas; 4. Conveniência; 5. Procrastinação; 6. Rotina sem planejamento). Baseado em dados empíricos coletados em famílias americanas, este estudo proporciona novas explicações, a exemplo de como o estoque abundante de comfort foods - uma forma de impulsionar tanto emoções positivas para si quanto mostrar afeto para crianças – pode gerar mais desperdício de alimentos. Em síntese, o segundo artigo identifica uma consequência negativa do afeto e da abundância de alimentos no contexto familiar, e apresenta um framework teoricamente relevante. Finalmente, o terceiro artigo, a partir do conjunto de dados dos estudos anteriores e de nova coleta com dez famílias, propõe uma tipologia comportamental do desperdício de alimento, uma contribuição original aos estudos de comportamento do consumidor. A identificação de cinco tipos de desperdiçadores de alimentos - (1) Mães carinhosas; (2) Cozinheiras abundantes; (3) Desperdiçadoras de sobras; (4) Procrastinadoras; (5) Mães versáteis - contribui para a teoria, enquanto implicações potenciais para educadores nutricionais e agentes públicos são exploradas a partir dos resultados. Como uma forma de explicar as características de cada um dos cinco tipos identificados, compara-se aspectos das amostras brasileira e norte-americana, que apresentam similaridades no comportamento de desperdício de alimento. Os níveis de desperdício percebidos por país também são comparados. Em suma, os achados dos três artigos podem contribuir para maximizar os resultados de campanhas de conscientização voltadas à mitigação do desperdício de alimento, e apresentam ideias para varejistas interessados em iniciativas de sustentabilidade. Mais abrangentemente, os resultados apresentados também podem ser aplicados para incrementar programas de combate à fome e projetos de educação nutricional realizados pelo setor público ou ONGs.
