The Herman–Chomsky Propaganda Model: A Critical Approach to Analysing Mass Media Behaviour

The Propaganda Model (PM), developed by Edward Herman and Noam Chomsky and published in Manufacturing Consent in 1988, sought to explain the behaviour of the mass media in the United States. Analysing the function, operation and effects of the media are essential to any understanding of contemporary societies and the article begins by sketching out the contours of the liberal-pluralist vs. critical-Marxist debate about the role of the media. The article then presents an overview of the PM, locates it within the field of media and communication studies, considers its reception, discusses a number of complementary methodological and theoretical approaches, and argues that the PM, more than 20 years after its formulation, continues to provide an invaluable tool for understanding the media within contemporary capitalist societies.     

Medical Uncertainty in Students Entering Medical School

Abstract

Uncertainty is a fundamental characteristic of medical practice. Renee Fox described three types of uncertainty: limitations in the body of medical knowledge, incomplete mastery of existing knowledge, and distinguishing between limitations and mastery of knowledge. This investigation administered ten Likert-format questions about uncertainty to 171 incoming medical students at one state medical school Items were reliable over a six week test-retest, and validity was supported by correlations with an Intolerance of Ambiguity scale. Entering students recognized that uncertainty exists in medical knowledge and mastery of medical knowledge. Factor analysis of the ten item uncertainty scale revealed three dimensions: uncertainty of the profession, practice certainty, and growth in uncertainty. No significant differences in the uncertainty items, scale, or factors existed by demographic characteristics or medical specialty preferences. These findings suggest that students are aware of issues surrounding uncertainty in medicine as they begin medical school, but medical uncertainty at this early stage in medical socialization is not sufficiently powerful to be associated with medical specialty preference.     

Does size really matter?: A reexamination of Sheldon's somatotypes and criminal behavior

In the mid-20th century, William Sheldon developed the idea of somatotypes in explaining different types of criminal behavior. Sheldon defined three body types believed to be associated with criminality: mesomorphs, who are athletically fit; endomorphs, who are overweight, and ectomorphs, who are characterized by fragility and thinness. Sheldon's research implied that mesomorphic individuals were more prone to committing violent and aggressive acts. This research explores a new method of somatotyping using the Body Mass Index (BMI). What follows is an examination of prisoners from the State of Arkansas, using information provided by the Arkansas Department of Correction's database on inmates. In particular, this paper examined prisoners’ physical characteristics such as age, height, and weight in comparison to the types of crimes that these prisoners committed. The findings of this paper show that the BMI is a useful alternative to traditional somatotyping techniques; the findings also suggest that a prisoner's somatotype is associated with criminal patterns while being a meager predictor of criminality. Methodological and theoretical implications of this study are discussed.     

Race, ethnicity, gender, and generational factors associated with the coming-out process among lesbian, and bisexual individuals

Age at coming out among gay/lesbian/bisexual (GLB) persons and sexual debut with same-gendered partners has typically been investigated in samples that do not reflect the racial and ethnic diversity of these communities. Addressing this limitation, data were collected from a diverse sample of men and women attending large-scale GLB community events in New York and Los Angeles in 2003 (N = 2,733). Compared to older cohorts, younger cohorts (18-24 year olds) of both men and women reported significantly earlier ages for sexual debut with same-gendered partners, and earlier ages for coming out to themselves and to others. Also, women began the process at later ages than men, as they reported coming out to themselves and sexual debut with a same-gender partner approximately two years later than men. There were no racial or ethnic differences in age out to self or others; however, persons of color were less likely to be out to their parents. Service providers, sexuality educators, and researchers should attend to the diversity in experience of coming out among GLB populations as they relate to the individuals gender, age, and racial and ethnic backgrounds.     

Balance of care—a user's view of a new approach to joint strategic planning

Planning for care of the Elderly has to face the problems of an increasing elderly population; a wide range of alternative ways of caring for them (at widely differing costs); the fact that services are provided by several different organisations all facing difficult financial constraints; a range of professional opinion about the desirability or otherwise of alternative patterns of care and use of resources; a lack of data on how care is at present distributed; the lack of a structure for organising such data as are available; and the lack of an appropriate computer-based model for manipulating the large number of data elements necessary to describe and help to evaluate alternative plans for the future. The Balance of Care approach to the Joint Strategic Planning of Health and Social Services provision for the Elderly, is being used in pilot applications in two Areas in the UK. Its contribution to the solution of the problems outlined above is described by authors from the two Areas. The approach and the underlying model can be extended to strategic planning for other client groups requiring non-acute care.     

Evaluation of the Uncertainty in an Oral Reference Dose for Methylmercury Due to Interindividual Variability in Pharmacokinetics

An analysis of the uncertainty in guidelines for the ingestion of methylmercury (MeHg) due to human pharmacokinetic variability was conducted using a physiologically based pharmacokinetic (PBPK) model that describes MeHg kinetics in the pregnant human and fetus. Two alternative derivations of an ingestion guideline for MeHg were considered: the U.S. Environmental Protection Agency reference dose (RfD) of 0.1 g/kg/day derived from studies of an Iraqi grain poisoning episode, and the Agency for Toxic Substances and Disease Registry chronic oral minimal risk level (MRL) of 0.5 g/kg/day based on studies of a fish-eating population in the Seychelles Islands. Calculation of an ingestion guideline for MeHg from either of these epidemiological studies requires calculation of a dose conversion factor (DCF) relating a hair mercury concentration to a chronic MeHg ingestion rate. To evaluate the uncertainty in this DCF across the population of U.S. women of child-bearing age, Monte Carlo analyses were performed in which distributions for each of the parameters in the PBPK model were randomly sampled 1000 times. The 1st and 5th percentiles of the resulting distribution of DCFs were a factor of 1.8 and 1.5 below the median, respectively. This estimate of variability is consistent with, but somewhat less than, previous analyses performed with empirical, one-compartment pharmacokinetic models. The use of a consistent factor in both guidelines of 1.5 for pharmacokinetic variability in the DCF, and keeping all other aspects of the derivations unchanged, would result in an RfD of 0.2 g/kg/day and an MRL of 0.3 g/kg/day.     

Only cord-cutters? Midwifery and childbirth in rural north India

This paper discusses the negative effect midwives' traditional birth procedures have on the promise of decreasing perinatal morbidity and mortality rates in North India. Specifically, 3 aims are achieved: 1) a discussion of the status of TBAs--traditional birth attendants--in different parts of India; 2) a presentation of field work on midwives, compiled from a recent study done in Uttar Pradesh; and 3) a discussion of the training offered to midwives by the Indian government and why it has been unsuccessful. In South India it is common for a woman to give birth in the presense of relatives and friends. The woman's dai - or midwife - is called in at the last moment, and is rarely in full charge of the childbirth. Because childbirth is thought of as a dirty and shameful occurrence, the dai is also thought of as an inferior menial -- not as an expert in her job. Most dais are illiterate, poor, and pursue their jobs after a marital breakdown has occurred. In fact, most midwives have no training or experience in baby delivery prior to their first delivery. However, one important role that the dai plays is in her diagnostic ability to advise women with complications to go to a health center. This is due to the fear that the midwife has of being associated with a bad birth which could ruin her reputation. The Indian government began a program in 1977 to train 1 dai for every 500 people. Most midwives are wary of government personnel because they often encourage the midwife to take more responsibility in the actual birth as well as in more complicated births. Because the dais, their clients, and their trainers, share such low opinions of midwifery, and because secular changes are rare in such a traditional country, midwife training prospects do not look promising.
