Domestic Cooking and Food Skills: A Review

Domestic cooking skills (CS) and food skills (FS) encompass multiple components, yet there is a lack of consensus on their constituent parts, inter-relatedness or measurement, leading to limited empirical support for their role in influencing dietary quality. This review assessed the measurement of CS and FS in adults (>16 years); critically examining study designs, psychometric properties of measures, theoretical basis and associations of CS/FS with diet. Electronic databases (PsychInfo), published reports and systematic reviews on cooking and home food preparation interventions (Rees et al. 2012 ; Reicks et al. 2014 ) provided 834 articles of which 26 met the inclusion criteria. Multiple CS/FS measures were identified across three study designs: qualitative; cross-sectional; and dietary interventions; conducted from 1998-2013. Most measures were not theory-based, limited psychometric data was available, with little consistency of items or scales used for CS/FS measurements. Some positive associations between CS/FS and FV intake were reported; though lasting dietary changes were uncommon. The role of psycho-social (e.g., gender, attitudes) and external factors (e.g. food availability) on CS/FS is discussed. A conceptual framework of CS/FS components is presented for future measurement facilitation, which highlights the role for CS/FS on food-related behaviour and dietary quality. This will aid future dietary intervention design.

Tratamiento de resultados en diseños cualitativos : La aplicación del Análisis Descriptivo

Este artículo presenta el Análisis Descriptivo como una estrategia del tratamiento de la información durante el proceso de investigación y su posible uso en estudios de diseño cualitativo. Muchas investigaciones en Ciencias Sociales y Humanas no contemplan la importancia de explicitar los soportes teórico-metodológicos de las inferencias explicativas o interpretación/es a la/s que se arriba, es decir, cómo es que se ha pasado del referente seleccionado (unidad de referencia), al argumento (modelo explicativo o interpretativo) con el que se lo pretende representar. De este modo, se suele ignorar el problema de la representación del referente en un dato tratable y la necesaria transformación del lenguaje natural (LN) en lenguaje descriptivo (LD). Se desarrollan dos ejemplos del campo de la Etología y de la Psicología, aplicando la estrategia metodológica del Análisis Descriptivo. En ellos se demuestra que la codificación que permite realizar este método toma en cuenta por un lado, la base de conocimientos e informaciones relativas a un dominio disciplinar particular y, por otro, permite evidenciar las inferencias seguidas en el razonamiento y las reglas de interpretación utilizadas para arribar a nuevos conocimientos

Missing steps in a staircase: a qualitative study of the perspectives of key stakeholders on the use of adaptive designs in confirmatory trials

Background Despite the promising benefits of adaptive designs (ADs), their routine use, especially in confirmatory trials, is lagging behind the prominence given to them in the statistical literature. Much of the previous research to understand barriers and potential facilitators to the use of ADs has been driven from a pharmaceutical drug development perspective, with little focus on trials in the public sector. In this paper, we explore key stakeholders’ experiences, perceptions and views on barriers and facilitators to the use of ADs in publicly funded confirmatory trials. Methods Semi-structured, in-depth interviews of key stakeholders in clinical trials research (CTU directors, funding board and panel members, statisticians, regulators, chief investigators, data monitoring committee members and health economists) were conducted through telephone or face-to-face sessions, predominantly in the UK. We purposively selected participants sequentially to optimise maximum variation in views and experiences. We employed the framework approach to analyse the qualitative data. Results We interviewed 27 participants. We found some of the perceived barriers to be: lack of knowledge and experience coupled with paucity of case studies, lack of applied training, degree of reluctance to use ADs, lack of bridge funding and time to support design work, lack of statistical expertise, some anxiety about the impact of early trial stopping on researchers’ employment contracts, lack of understanding of acceptable scope of ADs and when ADs are appropriate, and statistical and practical complexities. Reluctance to use ADs seemed to be influenced by: therapeutic area, unfamiliarity, concerns about their robustness in decision-making and acceptability of findings to change practice, perceived complexities and proposed type of AD, among others. Conclusions There are still considerable multifaceted, individual and organisational obstacles to be addressed to improve uptake, and successful implementation of ADs when appropriate. Nevertheless, inferred positive change in attitudes and receptiveness towards the appropriate use of ADs by public funders are supportive and are a stepping stone for the future utilisation of ADs by researchers.

The experience of being an advanced practice nurse within Australian acute care settings : a systematic review of qualitative evidence

Background There is a vast amount of international literature which, although agreeing on the need for advanced practice nurse roles, simultaneously debates and discusses the difficulties with nomenclature, definition and subsequent implementation of such roles. Due to this ambiguity it is difficult to equally compare evidence in this field across different countries. A context-specific systematic review on the qualitative evidence of the experience of being an advanced practice nurse in Australia has not been undertaken previously, however it is imperative for nursing managers and leaders to understand the complexities of advanced nursing roles in order to effectively utilise and retain these experienced and valuable nurses. With the creation of a national nursing regulating authority in 2010, it is timely to explore in-depth the experience of being an advanced practice nurse from a national perspective. Objective To identify the experience of being an advanced practice nurse working in Australian acute care settings. Inclusion criteria -Types of participants Registered nurses working in advanced practice roles in acute care settings throughout Australia. -Phenomena of interest The experience of being an advanced practice registered nurse working in an Australian acute care setting, as reported by the nurses themselves. -Types of studies Interpretive qualitative studies including designs such as phenomenology, grounded theory and ethnography. -Search strategy A three step search strategy was used to identify published and unpublished studies. The search process was conducted from August to October 2011 and considered published and unpublished studies from 1990 to October 2011. -Methodological quality Studies were appraised for methodological quality by two independent reviewers using the Joanna Briggs Qualitative Assessment and Review Instrument. -Data extraction Data was extracted from the papers included in the review using the standardised Joanna Briggs Institute Qualitative Assessment and Review Instrument data extraction tool. -Data synthesis Research findings were pooled using the Joanna Briggs Institute Qualitative Data and Review Instrument. Results Three published studies and one unpublished dissertation were included in the review. From these four studies, 216 findings were extracted, forming 18 categories which were then analysed to create six synthesised findings. Six meta-syntheses under the headings of expert knowledge, confidence, education, relationships, negative experiences and patient centred experience were formed from the findings. Conclusions The synthesised findings confirm that the experience of advanced practice nurses in Australian acute care settings is complex and greatly influenced personally and professionally by the organisation as well as the unpredictable nature of working with people.

Rank regression for analyzing ordinal qualitative data for treatment comparison

Ordinal qualitative data are often collected for phenotypical measurements in plant pathology and other biological sciences. Statistical methods, such as t tests or analysis of variance, are usually used to analyze ordinal data when comparing two groups or multiple groups. However, the underlying assumptions such as normality and homogeneous variances are often violated for qualitative data. To this end, we investigated an alternative methodology, rank regression, for analyzing the ordinal data. The rank-based methods are essentially based on pairwise comparisons and, therefore, can deal with qualitative data naturally. They require neither normality assumption nor data transformation. Apart from robustness against outliers and high efficiency, the rank regression can also incorporate covariate effects in the same way as the ordinary regression. By reanalyzing a data set from a wheat Fusarium crown rot study, we illustrated the use of the rank regression methodology and demonstrated that the rank regression models appear to be more appropriate and sensible for analyzing nonnormal data and data with outliers.

On the Problems of Mixing RCTs with Qualitative Research: The Case of the MRC Framework for the Evaluation of Complex Healthcare Interventions

In the perceived hierarchy of research designs, the results from randomized controlled trials are considered to provide the highest level of evidence. Indeed these trials have been upheld as the gold standard in research. The benefits and limitations of the randomized controlled trial as a method of evaluating the effectiveness of healthcare interventions are presented. The article then examines the different levels of complexity within healthcare interventions and the problems this poses in determining effectiveness. In an effort to provide a solution to this problem, the Medical Research Council produced a framework to assist investigators to develop and evaluate complex healthcare interventions. The framework is described with reference to an example of implementing and evaluating protocols for weaning patients in the intensive care unit. The framework is critiqued on the basis that it involves an ambiguous or contradictory ontology, which fails to articulate the relationship between the positivism of randomized controlled trials with the relativism of qualitative approaches. It is concluded that the use of realist strategies in combination with randomized controlled trials provides the most coherent solution to this quandary

Confined site construction: A qualitative review of issues regarding health and safety on-site

The construction industry is inherently hazardous, with a significant number of accidents and incidents occurring, particularly on confined construction sites. This research identifies, clarifies and tabulates the various managerial health and safety issues encountered on confined construction sites, based on a qualitative approach, to aid in the management of the complex health and safety concerns. The methodology is based on qualitative research incorporating case studies, interviews, causal loop diagrams and mind mapping. The key findings in the managerial issues in the management of health and safety on confined construction sites can be summarised as follows; (1) A lack of space, (2) Increased management of site personnel, (3) Overcrowding of the work place. The implication for the industry is that due to the sustained development of urban centres on a global scale, coupled with the increasing complexity of architectural designs, the majority of on-site project management professionals are faced with the onerous task of completing often intricate designs within a limited spatial environment, under strict health and safety parameters. The value of such research is to aid management professionals successfully identify the various managerial issues highlighted, resulting in the successful management of health and safety on a confined construction site.

Spectacle design preferences among Chinese primary and secondary students and their parents: A qualitative and quantitative study

Purpose: To identify the specific characteristics making glasses designs, particularly those compatible with adjustable glasses, more or less appealing to Chinese children and their parents. Patients and Methods: Primary and secondary school children from urban and rural China with < = -1.00 diopters of bilateral myopia and their parents ranked four conventional-style frames identified by local optical shops as popular versus four child-specific frames compatible with adjustable spectacles. Scores based on the proportion of maximum possible ranking were computed for each style. Selected children and their parents also participated in Focus Groups (FGs) discussing spectacle design preference. Recordings were transcribed and coded by two independents reviewers using NVivo software. Results: Among 136 urban primary school children (age range 9-11 years), 290 rural secondary school children (11-17 years) and 16 parents, all adjustable-style frames (scores on 0-100 scale 25.7-62.4) were ranked behind all conventional frames (63.0-87.5). For eight FGs including 12 primary children, 26 secondary children and 16 parents, average kappa values for NVivo coding were 0.81 (students) and 0.70 (parents). All groups agreed that the key changes to make adjustable designs more attractive were altering the round lenses to rectangular or oval shapes and adding curved earpieces for more stable wear. The thick frames of the adjustable designs were considered stylish, and children indicated they would wear them if the lens shape were modified. Conclusions: Current adjustable lens designs are unattractive to Chinese children and their parents, though this study identified specific modifications which would make them more appealing.

Photoelastic comparison of single tooth implant-abutment-bone of platform switching vs conventional implant designs

Objectives: The maintenance and stability of peri-implantar soft tissue seem to be related to the crestal bone around the implant platform and different implant designs connections might affect this phenomenon. The aim of this study was to evaluate by photoelastic analysis the stress distribution in the cervical and apical site of implant-abutment interface of conventional implant joints (external hex, internal hex and cone morse) and compare to the novel platform switching design. Materials and methods: It was fabricated photoelastic models using five different implant-abutment connection, one set of external hex (Alvim Ti, Neodent, Curitiba, Brazil), one set of internal hex (Full Osseotite, Biomet 3i, Florida, USA), one cone morse set (Alvim CM, Neodent, Curitiba, Brazil), and two sets of internal hex plus platform switching concept (Alvim II Plus, Neodent, Curitiba, Brazil) (Certain Prevail, Biomet 3i, Florida, USA). These models were submitted to two compressive loads, axial from 20 kgf (load I) and another (load II), inclined 45° from 10 kgf. During the qualitative analysis, digital pictures were taken from a polariscope, for each load situation. For the quantitative analyses in both situations of load, the medium, minimum and maximum in MPa values of shear strain were determined in the cervical and apical site. The Kruskal-Wallis test was used to compare the results between the different systems and between cervical and apical site were compared using Mann-Whitney U test. Results: The results from qualitative analysis showed less concentration of strain in the cervical area to the internal hex plus platform switching (Certain Prevail), in both situation of load. The same results were get in the quantitative analysis, showing less stress concentrations around the implant Certain Prevail with internal hex plus the novel design (17.9 MPa to load I and 29.5 MPa to load II), however, without statistical significant difference between the systems. Conclusion: The minor stress concentration strongly suggest the use of platform switching design as a manner to prevent bone loss around the implant-abutment platform. Clinical Significance: From the result of this study its possible to make clinical decision for implant system which provides implant components with platform switching characteristics.

Combining qualitative and quantitative methods to analyze serious games outcomes: A pilot study for a new cognitive screening tool

Computer games for a serious purpose - so called serious games can provide additional information for the screening and diagnosis of cognitive impairment. Moreover, they have the advantage of being an ecological tool by involving daily living tasks. However, there is a need for better comprehensive designs regarding the acceptance of this technology, as the target population is older adults that are not used to interact with novel technologies. Moreover given the complexity of the diagnosis and the need for precise assessment, an evaluation of the best approach to analyze the performance data is required. The present study examines the usability of a new screening tool and proposes several new outlines for data analysis.

Shifting accountability:a longitudinal qualitative study of diabetes causation accounts

We undertook a longitudinal qualitative study involving of 20 patients from Scotland who had type 2 diabetes. We looked at their perceptions and understandings of why they had developed diabetes and how, and why, their causation accounts had changed or remained stable over time. Respondents, all of whom were white, were interviewed four times over a 4-year period (at baseline, 6, 12 and 48 months). Their causation accounts often shifted, sometimes subtly, sometimes radically, over the 4 years. The experiential dimensions of living with, observing, and managing their disease over time were central to understanding the continuities and changes we observed. We also highlight how, through a process of removing, adding and/or de-emphasising explanatory factors, causation accounts could be used as “resources” to justify or enable present treatment choices. We use our work to support critiques of social cognition theories, with their emphasis upon beliefs being antecedent to behaviours. We also provide reflections upon the implications of our findings for qualitative research designs and sampling strategies.
