Older Men And Women

Objective: The link between marital quality and cellular aging remains underexplored. This study examined how both positive and negative marital quality were associated with salivary telomere length among partnered adults in the United States over the age of 50°years. Methods: Data were from the 2008 Health and Retirement Study ( N = 3203). Ordinary least squares regression was used to estimate the link between marital quality and telomere length. Results: While neither positive nor negative marital quality was significantly associated with telomere length among older women, positive and negative marital quality had an interacting effect on telomere length among men. Specifically, when negative marital quality was low, higher positive marital quality was associated with shorter telomere length, whereas when negative marital quality was high, higher positive marital quality was associated with longer telomere length. Discussion: The findings speak to the complex nature of intimate partnerships and the implications of these partnerships for cellular aging processes.

This study examines public employees’ donations to a workplace giving campaign at a large public university in the south-east of the United States. First, we employed logistic regression to predict the likelihood of donating through workplace giving programmes using a sample of employees at a large public university (N = 11,726). Second, we estimated an ordinary least squares regression to identify the significant predictors of donation value with a subsample of employee donors (n=1,832). Third, we developed donor profiles (for example, clusters) of employee benefactors using K-medoids clustering. Factors such as sex, age, education and salary were significant predictors of both being a donor and the donation amount. Additionally, employment duration was significantly related to being a donor and the donation amount, while job classification only predicted being a donor. Employee donors fell into five distinct clusters. These findings contribute to our knowledge of workplace giving campaigns and can be used to develop strategic marketing campaigns.

Political Variables

This paper examines the question of whether economic factors played an important role in determining strike activity in the United States in the first half of the twentieth century. A review of recent research shows one author, David Snyder, concluding that economic factors mattered little during that period and that union organization and political variables explained much more; and another, P. K. Edwards, concluding the opposite. A retest of these authors' analyses, employing ordinary least squares regression and a variety of measures, suggests that Snyder's position is more sound. This author argues, however, that Edwards was correct in claiming that economic factors are major determinants of the extent of unionism as well as of strike activity, and thus one needs to apply a two-stage least squares test of the Snyder hypothesis. When that is done, the results show that economic variables are highly significant determinants of strike activity throughout the pre-1949 period, but for the subperiod 1921–29 noneconomic factors also play a role.

When explaining the success of the Prohibition movement in the United States between 1900 and 1920, scholars argue that prohibitionists were able both to tap into the distrust of many rural, native-born, evangelical Protestants toward modern urban life and to bring together disparate groups of reformers around one goal: the elimination of the saloon. Furthermore, localized campaigns resulting in the elimination of saloons from many rural areas kept this base of voters energized, ultimately leading to impressive dry turnouts in statewide Prohibition referenda. This study extends and amplifies these findings through an analysis of three sets of factors on voting outcomes: the percentage of various demographic groups (urban, immigrant, and ritualistic religious populations) residing in a county; the distance of each county to saloons; the presence or absence of producers of alcohol in a county. Results of ordinary least-squares regression demonstrate that access to saloons and the percentage of immigrant and ritualistic church members in a county are the variables that most influence the results of Prohibition referenda. Furthermore, unlike what previous research has demonstrated, these variables have their greatest influence by affecting wet turnout rates.

Although the United States has elected an African American president, since that election there have been numerous indicators that racism remains a persistent, and complex, issue in America. Shortly after President Obama took office, for example, renowned Harvard University professor Henry “Skip” Gates was arrested for being uncooperative with the responding officer when police mistook him for a burglar at his own home. This incident served as a small reminder of the resilient nature of racism in the United States. More importantly, there has been an increase in the number of hate groups since 2008, and the proposed plans for an Islamic cultural center near the site of the former World Trade Center have initiated a wave of anti-Islamic sentiment. Despite the hope that Barack Obama would usher in a new era in race relations, it seems as though his election has brought to the surface tensions that some people assumed had disappeared. Among scholars of black politics, race serves as the central construct. In some cases, race serves as a lens through which other variables such as class and gender are filtered. In other cases, race serves as the key independent variable explaining a number of factors that influence the lives of blacks. Each of the texts reviewed in this essay examines issues of race to varying degrees, and each one reveals the complex nature and long-lasting impact of race on American society.

Fully Functioning

This article explores the origins of corporate public relations by examining the untold story of railroad development and expansion in the Commonwealth of Virginia. Understanding the circumstances surrounding Virginia’s pioneer railroads, which emerged at a tumultuous time within a state deeply divided over the related issues of the railroad and slavery, can enrich our comprehension of public relations history in corporate contexts. Fully functioning society theory (FFST) is used as a theoretical framework to guide the historical analysis of the rise of the railroad in Virginia in the 19th and 20th centuries. The article expands FFST’s application to historical inquiry and productively directs attention to the varied and complex nature of the emergence of corporate public relations without venerating or denigrating the field’s origins.

Although considerable progress has been made with the chemistry of juvenile hormone (Dahm, Roeller & Trost, 1968), studies on its mechanism of action in immature insects are still in a preliminary stage. Much of the recent work has been interpreted as showing an effect of juvenile hormone on the morphogenetic program through which an insect passes in the course of its ontogeny (Williams, 1961). It is the purpose of this paper to describe three studies which illustrate the complex nature of this developmental program in saturniid moths. Materials and Methods The saturniids (Antheraea polyphemus, Samia cynthia and Hyalophora cecropia) used in the present study were reared or purchased from dealers in the United States and England. Staging of animals was carried out by examining the state of the epidermis and the differentiation of adult structures through the pupal cuticle as described by Schneiderman & Williams (1954).

Tribal Politics

The northwestern theater of the War of 1812 brought the complex nature of tribal politics and diplomacy into full relief. While the militant, inter-tribal coalition led by Shawnee brothers Tecumseh and Tenskwatawa was one Indian strategy for reckoning with U.S. territorial expansion, the historiographical focus on the Shawnee brothers and their movement has obscured a range of shifting Indian objectives and strategies for negotiating the wartime upheaval. By closely examining inter-tribal rivalries and coalitions, as well as tensions within Indian polities, we see a broader spectrum of Indian agendas in action during the War of 1812. Those agendas included neutrality, spying for or outright alliance with the United States, and situational Indian participation in the conflict when the British made gains early in the war. Well after Tecumseh’s death, we also see the geopolitical influence of western Indian forces, particularly the Potawatomis, Sauks, and the Sioux, on the conflict. For an era so closely associated with Indian prophecy and millenarianism, pragmatism most often reigned.

Over Time

Transportation agencies at the local, state, and federal levels in the United States (U.S.) have shown a growing interest in expanding bicycle infrastructure, given its link to mode shift and safety goals. These projects, however, are far from universally accepted. Business owners have been particularly vocal opponents, claiming that bicycle infrastructure will diminish sales or fundamentally change the character of their neighborhoods. Using the case of San Francisco, this research explores the relationship between bicycle infrastructure and business performance in two ways: change in sales over time, and a comparison of sales for new and existing businesses. An ordinary least squares regression is used to model the change in sales over time, isolating the effect of location on bicycle infrastructure while controlling for characteristics of the business, corridor, and surrounding neighborhood. Through a series of t-tests, average sales for businesses that pre-date bicycle infrastructure and for those that opened after the installation of such projects are compared. Ultimately, the research suggests that location on bicycle infrastructure and changes in on-street parking supply generally did not have a significant effect on the change in sales, with a few exceptions. Businesses that sell goods for the home or auto-related goods and services saw a significant decline in sales when located on corridors with bike lanes. New and existing businesses generally had similar sales, though not across the board. New restaurants and grocery stores had significantly higher sales than their existing counterparts, suggesting bicycle infrastructure may attract more upmarket businesses in those industries.
