Alarmed: sensory approaches to improving medical alarm systems

Medical alarms sound incessantly, loudly, and dissonantly, contributing to an already noisy ICU and OR soundscape, and ultimately harming both patients and staff. Sometimes triggered in error, the sheer number of alarms distracts health care professionals and results in sensory overload that contributes to hospital staff’s alarm fatigue. In turn, staff become increasingly likely to ignore alarms instead of acting on them. Furthermore, the patients’ sensitivity to alarms disturbs their hospital stay, raises their stress levels, and impedes their recovery process, with sometimes lasting effects. This article considers the sensory effects of hospital alarms and possibilities for redesigning future alarm systems, with the goal of eventually creating a more calming, less stressful, and safer hospital soundscape environment for all.

The Politics of Expanding Healthcare Access to the Poor and Informal Sectors

How do the politics of agenda setting and policy adoption operate in the arena of healthcare reform in the industrializing world? Literature on the twenty‐first‐century developmental state emphasizes the role of democratic competition and civil society in causing political parties to take up new agendas, while power resources theory stresses the role of left‐wing political parties and labor unions in policy adoption. Yet, core tenets of these theories have not been considered extensively in light of dynamics in the industrializing world. This article examines the politics of policy adoption in countries that have recently aimed to provide healthcare access and financial protection to the poor and people in the informal sector in Mexico and Turkey. In line with literature on the twenty‐first‐century developmental state, we find democratic competition to play an important role in causing political parties to take up new agendas. However, examination of the cases illuminates surprising dynamics that challenge important elements of sociological theory: right‐leaning political parties played important roles in adoption, while labor unions and left‐wing parties oppose reform in the cases. Public health‐minded physicians leading change teams played important roles in agenda setting and leading the process of implementation.     

Inference on cointegrating ranks using lr and lm tests based on pseudo-likelihoods

This paper considers Lagrange Multiplier (LM) and Likelihood Ratio (LR) tests for determining the cointegrating rank of a vector autoregressive system. n order to deal with outliers and possible fat-tailedness of the error process, non-Gaussian likelihoods are used to carry out the estimation. The limiting distributions of the tests based on these non-Gaussian pseudo-)likelihoods are derived. These distributions depend on nuisance parameters. An operational procedure is proposed to perform inference. It appears that the tests based on non-Gaussian pseudo-likelihoods are much more powerful than their Gaussian counterparts if the errors are fat-tailed. Moreover, the operational LM-type test has a better overall performance than the LR-type test. Copyright O 1998 by Marcel Dekker, Inc.     

Profiles of Housing Cost Burden in the United States

In this study, the ordered logistic regression model indicates that renters suffer a greater housing cost burden than homeowners and that the lower the income of the household, the larger the portion of income that is spent for housing. Further, the model also shows that the burden of high housing costs falls disproportionately on certain groups of American households. Compared to the reference group, two single-risk groups (Asian-American households and households with three or more children) and two dual-risk groups (female-headed households with three or more children and minority households with three or more children) tend to have a higher risk of excessive housing costs. Elderly households and three elderly-related groups (female-headed elderly households, minority elderly households, and female-headed minority elderly households), however, tend to have a lower risk of housing cost burden than other households. The housing cost burden of the reference group is comparable to the housing cost burden of each of the following groups: for single female-headed households; Black households; Hispanic households; and female-headed minority households. The policy implications of these findings are discussed in the paper.     

Principles for Conduct of Pest Risk Analyses: Report of an Expert Workshop

The North American Free Trade Agreement (NAFTA) and the General Agreement on Tariffs and Trade (GATT) have focused attention on risk assessment of potential insect, weed, and animal pests and diseases of livestock. These risks have traditionally been addressed through quarantine protocols ranging from limits on the geographical areas from which a product may originate, postharvest disinfestation procedures like fumigation, and inspections at points of export and import, to outright bans. To ensure that plant and animal protection measures are not used as nontariff trade barriers, GATT and NAFTA require pest risk analysis (PRA) to support quarantine decisions. The increased emphasis on PRA has spurred multiple efforts at the national and international level to design frameworks for the conduct of these analyses. As approaches to pest risk analysis proliferate, and the importance of the analyses grows, concerns have arisen about the scientific and technical conduct of pest risk analysis. In January of 1997, the Harvard Center for Risk Analysis (HCRA) held an invitation-only workshop in Washington, D.C. to bring experts in risk analysis and pest characterization together to develop general principles for pest risk analysis. Workshop participants examined current frameworks for PRA, discussed strengths and weaknesses of the approaches, and formulated principles, based on years of experience with risk analysis in other setting and knowledge of the issues specific to analysis of pests. The principles developed highlight the both the similarities of pest risk analysis to other forms of risk analysis, and its unique attributes.     

The American sociologist: Characteristics in the 1990s

This article describes the characteristics, theoretical preferences, and political orientations of sociologists in the United States. The findings are the most representative of their kind reported to date. Other professional groups, such as psychiatrists, have been studied over time (Gallagher, 1977; Gallagher et al., 1987; Gallagher et al., 1990), but studies of sociologists have been almost non-existent. In fact, there has only been one study of this nature conducted in the 1990s, and that one sampled only sociologists whose names appeared on the membership list of the American Sociological Association (Sanderson and Ellis, 1992). However, that sampling frame did not provide a representative cross-section of American sociologists because it excluded the large proportion of sociologists who are not members of the ASA and who probably are systematically different than members. It is ironic that sociologists who intensively study the characteristics of all sorts of groups know so little about themselves. That is a major reason why this project was undertaken.     

The Rise in Union Wage Premiums in South Africa

The earnings premium received by African, urban, male union members in South Africa, as compared to other regular, urban male employees, is explored using two national sample surveys conducted in 1985 and 1993. The historical setting of this change is of particular interest, in the light of the transformation from the apartheid regime. Union membership grew very rapidly during this interval, as earlier prohibitions on African unions were lifted. Subsequently, the high rates of unemployment and segmentation of the labor force have been issues of central concern to the new government, elected in 1994. In this context, the paper extends prior methodology, by systematically comparing possible approaches to estimation, in addition to contributing fresh empirical results. Four approaches to estimation are adopted, allowing for: a single earnings regime with union dummy variable; the possibility of different earnings regimes among union members as compared to non‐members; endogenous switching between such regimes; sample selection arising from lack of employment and from division between regular and informal work. A series of tests on nested specifications indicate the importance of recognizing endogenous switching between differing pay structures in the covered and uncovered sectors. However (as with previous research on the South African labor market), no sample selection is detected with respect to employment status. The results suggest that collective bargaining resulted in wage compression among the expanding union membership while significantly widening the gap between members and non‐members. The latter widening gap cannot be attributed to the changing composition of union membership as reflected in observed characteristics of employees.     

Does the number of sex partners affect educational attainment? Evidence from female respondents to the Add Health

We use data on young women from the National Longitudinal Study of Adolescent Health to explore the relationship between number of sex partners and educational attainment. Using the average physical development of male schoolmates to generate plausibly exogenous variation in number of sex partners, instrumental variables estimates suggest that number of sex partners is negatively related to educational attainment. This result is consistent with the argument that romantic involvements are time consuming and can impose substantial emotional costs on young women.
