Exploring professional orientations to community voice in professional practice settings: The IMAP process

The tension between technical experts and the populations they seek to serve is well established in the literature examining professional social problem solving. In this piece, I examine this tension as one between the distinct discursive worlds of technical expertise and community voice. I develop an analytic process, IMAP, for exploring this tension by looking at a wide variety of professional orientations around a relatively fixed concept of community voice. IMAP involves I&barbelow;dentifying social problem solvers, M&barbelow;apping social problem solvers' claims, A&barbelow;nalyzing professional orientations that arise from this mapping, and P&barbelow;redicting, diagnosing, and remediating conflicts. IMAP can be used by analysts external to social problem solving settings or by social problem solvers themselves. The use of IMAP by external experts poses questions of expert alignment with either of the discursive worlds. I examine two cases in public health practice settings: a mobile immunization service and the efforts of a foundation to improve health in an inner-city neighborhood. I develop four modal types that can be anticipated in social problem solving settings or, more specifically, in public health practice. Understanding of these “world views” can enhance mutual understanding between public health professionals and between public health professionals and the communities they seek to serve. IMAP might also address ongoing conflicts to clarify differences in unspoken normative commitments and the impact of these on social problem solving. I discuss implications of the research for public health practice and further research in the area. ^

Folklore, fad, and fashion: The concept of misconduct in science redefined

This study is an analytical investigation of the nature and implications of the current conceptions of scientific misconduct, arguing that the question of what constitutes misconduct in science is significantly more complex than what conventionally has been believed. Complicating the definitions of misconduct are the differences between professional science and non-scientific professions, in their respective norms of what constitutes valid knowledge, and what counts as appropriate and inappropriate practice. While institutionalized science claims that there is clear differentiation between its standards of validity and those of the non-scientific professions, this paper argues that, when it comes to misconduct, the perceived boundaries between the scientific and non-scientific professions are breached; the practice standards that science currently employs in self-policing misconduct have come to resemble the minimal juridical standards of practice that other professions employ. This study attempts, despite erosion of these traditional boundaries, to move from legalistic standards of scientific practice to intramural standards of practice, and in so doing, to hold scientific practice to a higher standard than ordinary public conduct. The result is a clearer understanding of scientific misconduct to aid those individual scientists who are required to make onerous determinations about the appropriateness of specific practices by their peers. ^

Prevalence of methicillin-resistant Staphylococcus aureus (MRSA) nasal colonization among dental professionals

Background. MRSA (methicillin-resistant Staphylococcus aureus) is a multi-drug resistant bacterium that is quite prevalent in social environments where close person-to-person contact and crowding are an issue. In dental settings, the likelihood of transmission of MRSA may be higher than among other healthcare practitioners because of the close proximity between a patient's nose (where MRSA colonizes) and the field of procedure (the mouth) to the dental professional. Objective. To estimate the prevalence of MRSA nasal colonization among dental professionals (dentists and dental hygienists) in the Greater Houston Metropolitan Area, Texas, and analyze its associations with demographic, professional and personal protective equipment-related variables. Methods. 800 dental professionals (400 dentists and 400 dental hygienists) were randomly selected in the Greater Houston Metropolitan Area. Multiple waves of nasal swab kits and a self-administered questionnaire were mailed to increase the response rate of the study population. The swabs were cultured on chromagenic agar growth medium and bacterial growth results were evaluated after 18 hours. Positively selected bacterial colonies were confirmed as MRSA by further culturing these isolated bacteria on blood agar plates. Associations between positive nasal swabs and self-reported professional practice patterns, personal protective equipment use and demographics were analyzed using multiple logistic regression. Main Results. Completed questionnaires and nasal swabs were received from 496 study participants (68%). Fourteen cultures were positive for MRSA (4.2% among dentists and 1.6% among dental hygienists, p=0.07). After adjusting for gender, dental hygienists had a significantly lower prevalence of nasal colonization of MRSA as compared to dentists (OR: 0.20, 95% CI: 0.05–0.75). No other significant associations or interactions were found. Conclusion. The prevalence of nasal colonization with MRSA among dentists is similar to that reported for health care workers in general, whereas prevalence among dental hygienists is only slightly above that of the general population (1%). Differences in practice patterns and use of personal protective equipment did not explain this difference in this study, and was possibly due either to residual confounding or unexplored risk factors. Increased prevalence of MRSA among dentists warrants further investigation as to the reason for the increased rate and to allow implementation of measures to avoid transmission and progression to disease. ^

Demographic analysis of Certified Industrial Hygienists (CIH) with the use of survival analysis techniques

Objective. The goal of this study is to characterize the current workforce of CIHs, the lengths of professional practice careers of the past and current CIHs.^ Methods. This is a secondary data analysis of data compiled from all of the nearly 50 annual roster listings of the American Board of Industrial Hygiene (ABIH) for Certified Industrial Hygienists active in each year since 1960. Survival analysis was performed as a technique to measure the primary outcome of interest. The technique which was involved in this study was the Kaplan-Meier method for estimating the survival function.^ Study subjects: The population to be studied is all Certified Industrial Hygienists (CIHs). A CIH is defined by the ABIH as an individual who has achieved the minimum requirements for education, working experience and through examination, has demonstrated a minimum level of knowledge and competency in the prevention of occupational illnesses. ^ Results. A Cox-proportional hazards model analysis was performed by different start-time cohorts of CIHs. In this model we chose cohort 1 as the reference cohort. The estimated relative risk of the event (defined as retirement, or absent from 5 consecutive years of listing) occurred for CIHs for cohorts 2,3,4,5 relative to cohort 1 is 0.385, 0.214, 0.234, 0.299 relatively. The result show that cohort 2 (CIHs issued from 1970-1980) has the lowest hazard ratio which indicates the lowest retirement rate.^ Conclusion. The manpower of CIHs (still actively practicing up to the end of 2009) increased tremendously starting in 1980 and grew into a plateau in recent decades. This indicates that the supply and demand of the profession may have reached equilibrium. More demographic information and variables are needed to actually predict the future number of CIHs needed. ^
