Aligning theory and methodology in mixed methods research: Before Design Theoretical Placement

When a theoretical framework (and its components) is not clearly linked to research methods, researchers risk designing flawed studies, wherein the stated research question is inconsistent with the research design. Explicitly identifying one’s theoretical orientation can provide an orderly schematic for linking observations from separate investigations (i.e. qualitative, quantitative) thereby facilitating understandings and guiding research designs particularly in fields of social and health sciences where complex phenomena are an aspect of the subject of inquiry. Although this has been established, how researchers might position their research theoretically to guide mixed methods research is less clear. In this paper, we propose the Before Design Theoretical Placement as a general guide for specifying and locating studies in a broader theoretical grounding, and discuss how it may inform overall study considerations. We then use this approach to illustrate how theories and methods can work together to facilitate professional knowledge development from a relational perspective.     

Modeling the Dose Response Relationship of Waterborne Acanthamoeba

This study developed dose response models for determining the probability of eye or central nervous system infections from previously conducted studies using different strains of Acanthamoeba spp. The data were a result of animal experiments using mice and rats exposed corneally and intranasally to the pathogens. The corneal inoculations of Acanthamoeba isolate Ac 118 included varied amounts of Corynebacterium xerosis and were best fit by the exponential model. Virulence increased with higher levels of C. xerosis. The Acanthamoeba culbertsoni intranasal study with death as an endpoint of response was best fit by the beta‐Poisson model. The HN‐3 strain of A. castellanii was studied with an intranasal exposure and three different endpoints of response. For all three studies, the exponential model was the best fit. A model based on pooling data sets of the intranasal exposure and death endpoint resulted in an LD₅₀ of 19,357 amebae. The dose response models developed in this study are an important step towards characterizing the risk associated with free‐living amoeba like Acanthamoeba in drinking water distribution systems. Understanding the human health risk posed by free‐living amoeba will allow for quantitative microbial risk assessments that support building design decisions to minimize opportunities for pathogen growth and survival.     

Limiting relationships through sousveillance video based digital advocacy: multi-modal analysis of The Nervous CPS Worker

ABSTRACT

Digital media technology and Internet-based/social media sharing are shifting the contexts and processes of social work, including the relationships emerging in practice. The Nervous CPS Worker, a digital video shared via YouTube, provides a concrete practice-based example of the use of social media self-advocacy by professional foster parents. This case-study demonstrates the fragmented and shifting power-relations brought to bear within contemporary social work. Multi-modal analysis facilitates the development of a layered qualitative understanding of this video, shaped by the researcher’s inter-textual relationship with the material. Supplemental online texts are applied to the Nervous CPS Worker and relevant scholarship, including discipline specific knowledge, reveals the layered and convergent meaning making processes present in this video through the use of auditory communication, visual representations and genre. Analysis demonstrates how contemporary social work contexts, such as neoliberalism, and standardisation are implicated in practice and how identity and context compete for recognition and space within the home visit depicted in this video.     

Anti-muslim sentiment on social media in China and Chinese Muslims’ reactions to hatred and misunderstanding

This study documents the extensive online anti-Muslim sentiment in China as well as the use of social media by Chinese Muslims from various backgrounds to engage with the online public sphere and respond to this hostile discourse. We analyzed more than 10,000 social media posts on Weibo relating to Muslims and Islam and conducted in-depth interviews with 34 Chinese Muslims who were active users of social media. Our findings reveal an anti-Muslim online frame, and we detail the ways in which Chinese Muslims have sought to influence public policy in order to protect their rights. The participants in this study responded to hateful posts and worked to increase the understanding of their religion and culture by providing glimpses of their daily lives and by discussing Islam. Nevertheless, owing to government censorship and to the prevailing Han-centric discourse, Chinese Muslims continue to face numerous risks and challenges, particularly in coping with the ideological conflict between their religion and the atheistic ruling party.     

Assessing the Benefits and Costs of Homeland Security Research: A Risk-Informed Methodology with Applications for the U.S. Coast Guard

This article describes a methodology for risk-informed benefit–cost analyses of homeland security research products. The methodology is field-tested with 10 research products developed for the U.S. Coast Guard. Risk-informed benefit–cost analysis is a tool for risk management that integrates elements of risk analysis, decision analysis, and benefit–cost analysis. The cost analysis methodology includes a full-cost accounting of research projects, starting with initial fundamental research costs and extending to the costs of implementation of the research products and, where applicable, training, maintenance, and upgrade costs. The benefits analysis methodology is driven by changes in costs and risks leading to five alternative models: cost savings at the same level of security, increased security at the same cost, signal detection improvements, risk reduction by deterrence, and value of information. The U.S. Coast Guard staff selected 10 research projects to test and generalize the methodology. Examples include tools to improve the detection of explosives, reduce the costs of harbor patrols, and provide better predictions of hurricane wind speeds and floods. Benefits models and estimates varied by research project and many input parameters of the benefit estimates were highly uncertain, so risk analysis for sensitivity testing and simulation was important. Aggregating across the 10 research products, we found an overall median net present value of about $385 million, with a range from $54 million (5th percentile) to $877 million (95th percentile). Lessons learned are provided for future applications.     

Toward a more perfect union: The career and contributions of Robin M. Williams

For more than half a century the sociologist Robin M. Williams, has used his consummate analytical and communicative skills to assess and explain the character, quality and contradictions of American culture. His career as a scholar, teacher, editor and leader in our profession, and his extensive writings—especially but not exclusively in the realm of “intergroup relations”—offer a powerful counter to the contention that sociology is moribund, that its practitioners have little of importance to say about the real lives of real people or to contribute to debates over America’s unfinished agenda. For students and for younger colleagues in sociology, he is a perfect example of what his one-time teacher, Robert K. Merton, must have had in mind when he first used the expression,“role-model.” (See Merton 1981) At once a courtly gentleman with a soft-southern voice and an easy-going manner reminiscent of another time and place, Robin M. Williams is also very much the modern social scientist, a hard-driving worldly philosopher with a feisty spirit, an avid curiosity, and a rare gift for demonstrating in word and deed the integration of the Comtean trilogy of theory, research and practice. He is a role model, par excellence.     

Child Psychiatry in the Chinese Setting

This article introduces the history and social background and describes the present situation of child psychiatry in China. Certain Chinese social, political and cultural issues are explored, as the one-child policy and the Chinese family structure. Numerous currents of thought coexist in Chinese child psychiatry. Four examples of mental health disorders in child and adolescent psychiatry and their treatments in the Chinese public health care system are described (attention deficit hyperactivity disorder, anorexia nervosa, posttraumatic stress disorder and internet addiction).
