Validation of qualitative microbiological test methods

This paper considers a statistical model for the detection mechanism of qualitative microbiological test methods with a parameter for the detection proportion (the probability to detect a single organism) and a parameter for the false positive rate. It is demonstrated that the detection proportion and the bacterial density cannot be estimated separately, not even in a multiple dilution experiment. Only the product can be estimated, changing the interpretation of the most probable number estimator. The asymptotic power of the likelihood ratio statistic for comparing an alternative method with the compendial method, is optimal for a single dilution experiment. The bacterial density should either be close to two CFUs per test unit or equal to zero, depending on differences in the model parameters between the two test methods. The proposed strategy for method validation is to use these two dilutions and test for differences in the two model parameters, addressing the validation parameters specificity and accuracy. Robustness of these two parameters might still be required, but all other validation parameters can be omitted. A confidence interval‐based approach for the ratio of the detection proportions for the two methods is recommended, since it is most informative and close to the power of the likelihood ratio test.

Teaching Note—Teaching Intersectionality: Transforming Cultural Competence Content in Social Work Education

Intersectionality has been gaining momentum among social workers as a framework to allow a fuller understanding of the complexity of diverse social identities and the impact of social structures on power, privilege, and oppression. However, the application of intersectionality to teaching in social work education has been relatively absent in the literature. This article describes a 3-hour graduate-level classroom exercise designed to increase knowledge and proficiency of intersectionality. Critical self-reflections of the participants’ experiences are provided to illustrate the evolving growth and awareness that can result from the educational process using this framework. Examples and suggestions for reading assignments and classroom activities are offered. Implications for social work education and future directions are discussed.     

The Value of the Relationship in Volunteer Home Support Programs Working with Vulnerable Families

This paper reports on a program evaluation project that included interviews with 35 parents from high-risk backgrounds who received home volunteer support as part of the Dalwood Volunteer Home Support Program. It provides insight into the meaning and value parents attach to the volunteer relationship. The evaluation findings suggest that home volunteer support was associated with parent perception of increased wellbeing, decreased social isolation, and an improved relationship with their child. The results also suggest that parents perceived their relationship with their volunteer as significant in providing a secure base relationship.     

Can a Unified Service Delivery Philosophy Be Identified in Aging and Disability Organizations? Exploring Competing Service Delivery Models Through the Voices of the Workforce in These Organizations

Services for older adults and younger people with disabilities are increasingly merging, as reflected in the creation of Aging and Disability Resource Centers (ADRCs). Using ADRCs to coordinate services is challenging, primarily because these fields have different service delivery philosophies. Independent Living Centers, which serve people with disabilities, have a philosophy that emphasizes consumer control and peer mentoring. However, the aging service delivery philosophy is based in a case management or medical model in which the role of consumers directing their services is less pronounced. Using institutional logics theory and a qualitative research design, this study explored whether a unified service delivery philosophy for ADRCs was emerging. Based on focus groups and questionnaires with staff from ADRCs, findings revealed that competing service delivery models continue to operate in the aging and disability fields.     

Restoring and Sustaining Home: The Impact of Home Modifications on the Meaning of Home for Older People

ABSTRACT

The importance of a supportive home environment to successful aging has been well-established in the literature, with home modifications increasingly acknowledged as ways of removing barriers to function and increasing independence for older people. Home modification literature and practice primarily focus on the home environment as a physical space in which to perform tasks and on the impact of modification on competencies and function. Home, however, is much more than a physical environment. Within a transactive framework, people and places are seen as engaged in a dynamic, reciprocal relationship through which home becomes a place of significant personal meaning. Through a qualitative framework, this study examines the experience of older people living in the community who are recipients of a home modification service. It explores the impact modifying the physical environment has on their experience of home as a place of meaning and provides insight into how home modifications can strengthen the home as a place of personal and social meaning as well as improve safety and comfort for the older person at home.     

Social Exclusion and Poverty: Translating Social Capital into Accessible Resources

This article investigates the dynamic multi‐dimensional processes through which the poor become excluded from social participation. Drawing on social capital literature, it traces how bridging and bonding capital do not always translate into expected levels of social participation. It does so by detailing research findings from low income focus groups undertaken in Dunedin, New Zealand. These describe the experiences of group members in attempting to manage connections around employment, their own broader social participation or the participation of their children. In each case, the study highlights the difficulties of translation they experienced: in particular, translating available bridging or bonding capital into useful social, cultural or economic resources which could mitigate their social exclusion or enable fuller social participation.     

Navigating religious diversity: exploring young people’s lived religious citizenship in Indonesia

Against the backdrop of several concerning reports which have noted growing socio-religious conservatism and intolerance amongst Indonesia youth, this study examined how school-aged Indonesian young people navigate encounters with religious difference in their everyday lives. Recognising the significance of religious and citizenship education curricula, the research included classroom observations and interviews with 20 religiously-diverse Indonesian young people in three purposively selected high schools in Jakarta. The paper reveals that participants in all three schools agreed that religious studies and their personal religious frameworks were central to their approaches toward religious tolerance. However, their lived everyday experiences of rubbing shoulders with religious ‘others’, expanded upon and critiqued the narrowness and rigidity of these frameworks and showed greater religious inclusivity. Through this analysis the paper integrates prior work on ‘lived religion’ and ‘lived citizenship’ to fuse a ‘lived religious citizenship’ concept, arguing that this adds depth to both fields by recognising that religion cannot be separated from the experience of being a citizen. A focus on lived religious citizenship provides a deeper account of individual identity and highlights the importance of qualitative studies focused on the living out of religion and citizenship.
