Let f (x) be a probability density function. The problem of estimating the functional ∫f2(x) dx by the Method of Frequency Moments is considered. An expression for the asymptotic mean squared error of the proposed estimator is given. The results are applied to the estimation of the reciprocal of the scale parameter in the Cauchy and Pareto distributions. An approximation for the bias in the Method of Frequency Moments is given, and a two step estimation procedure is discussed.

We have witnessed, over the past century, an evolution in the manner in which students with disabilities are educated. Indeed, the quality of education students with special needs receive, in many ways, may be more aptly termed a revolution – from a legal and pedagogical perspective. The tremendous strides special education has made during this period of time has resulted in the current situation in which students with special needs are placed in the least restrictive environment, which often is an inclusive classroom in which general education and special education teachers work together in a collaborative, co-teaching environment. This chapter traces the events, legislation, and court cases that provide the historical context for this situation. In addition, models and essential components of co-teaching are examined, as well as the roles and requisite skills of general education and special education co-teachers. Of critical importance, in the success of co-teaching, is the need for special education and general education teachers to approach the curriculum planning and instructional processes in a collaborative and cooperative manner in order to achieve optimum results from the resulting co-teaching partnership. Finally, the assessment of special education and general education co-teaching efficacy is discussed, specifically through the use of three assessment rubrics used to evaluate co-teaching, co-planning, and co-assessment.

This paper examines the labor policies of the United Typothetae of America (UTA) from its birth in 1887 through the late 1920s and argues that labor policy differences among its members (personified by two prominent New York City-based printing employers, Theodore DeVinne and Charles Francis) created a “house divided” that not only prevented it from creating and maintaining a unified labor policy but also ultimately led to its demise as an employers' association and reconstitution primarily as a trade association. It will do so by analyzing key episodes in the UTA's labor history to show how the two competing labor philosophies – DeVinne's absolute authority & independence and Francis's stability & order – interacted with industry conditions – intense price competition, a decentralized industry structure, proprietor autonomy, the relative power of unions, and economic conditions – to impact the UTA's labor policies and its institutional survival. The UTA's experience reveals the diversity of American employers' experiences as well as the challenges that they have faced when attempting to act collectively in the industrial relations arena. Moreover, recent IR research on employers' associations around the world also reveals that, as unions have declined in power, many also are shifting their focus away from labor relations to other member services.

Focusing on the sociological clarification based on structural pluralism, this study explores the degree to which social media users who comment on the news posts of local newspapers use uncivil remarks and words that reflect their moral foundations.

This computer-assisted data collection produces three types of datasets that include numerous social media comments. To explore the association between moral foundations and incivility, both quadratic association procedure (QAP) and multiple regression QAP (MRQAP) are implemented.

The findings suggest that social media users who comment on the news posts of urban-located newspapers tend to use more uncivil words compared to social media users who comment on the news posts of suburban and rural-based newspapers. Individuals who comment on the news posts of urban-based newspapers tend to show a wider range of moral foundation spectrums than those who comment on the posts of rural and suburban newspapers. Lastly, there are significant associations between moral-vice components and incivility in response to urban- and suburban-located newspapers' social media posts.

The employed bag-of-words may not completely capture incivility given that social media users can use nuanced and metaphoric terms instead of explicitly uncivil terms. Even though this study systematically selected local newspapers' social media accounts, the contextual factors of other newspapers in politically slanted communities could be different.

The findings of this study provide meaningful and practical implications for journalists and news reporters. The inherent rudeness and aggressiveness of social media users can drive them to use uncivil and moral-harm words against a particular person or group.

Under the circumstance that fake news and politically slanted news content are widely distributed in the United States, social media users may easily express negative emotions toward news stories or the journalists who post the stories.

Structural pluralism particularly specializes in explaining why and how the contextual factors of news stories differ depending on community complexity. Building on the reasoning of structural pluralism in the social media context, this study investigates the degree to which social media users who comment on the news posts of local newspapers employ uncivil remarks and moral foundation words.

This chapter examines the implications of career achievement for divorce, and whether they differ for men and women. Consistent with theory suggesting that women’s workplace achievement violates traditional expectations of gender and marriage, therefore creating domestic strain, the authors predict that career achievement is associated with a greater risk of divorce for women, but not for men. Using data from the Academy Awards, the authors find that for women, a sudden shift in achievement from winning an Oscar increases their risk of divorce compared to Best Actress nominees. There was no difference in the risk of divorce between Best Actor winners and nominees. The authors additionally examine two potential mitigating factors: whether the actor was already successful at the time of their marriage, and whether their spouse was comparably successful. For Best Actress winners, but not for Best Actor winners, the authors find evidence for the latter, indicating that women’s marriages are more stable when spouses are equally successful, or when relative achievement within the couple aligns with broadly-held norms of traditional marriage.

School gardening and garden-based learning (GBL) have gained great popularity in recent years, and the COVID-19 pandemic forced many educators to think creatively about safe, outdoor education. Scholarship from diverse disciplines has demonstrated the positive impact of GBL on student learning, attitudes toward school and various health outcomes. Despite widespread interest in school gardening, GBL remains absent from most teacher education programs. This is a critical disconnect, as teacher education programs deeply inform the pedagogy of future teachers. In this article, the authors discuss an independent study course for pre-service teachers designed to bridge this gap and share the perspectives of the future teachers who completed the course.

To understand and evaluate the experiences of the preservice teachers engaged in the GBL independent study course, the authors conducted an exploratory qualitative case study.

The authors argue that GBL curriculum integration in teacher education programs, along with garden-focused PDS partnerships, can be powerful levers in expanding gardening initiatives and preparing pre-service teachers to garden with their future students.

The authors also provide GBL suggestions for universities and partnership schools.

This study examined whether life satisfaction varied among women who occupy different motherhood statuses, and if these variations were influenced by differences in women’s internalization of cultural motherhood norms. We distinguished among women as biological mothers, stepmothers, and “double mothers,” who were both biological and stepmothers. We also included two groups of women without children: voluntary childfree and involuntary childless women.

Data were drawn from the National Study of Fertility Barriers and analyzed using OLS regression.

Biological mothers reported greater life satisfaction than women in other motherhood statuses. Accounting for the internalization of motherhood norms, double mothers had significantly lower life satisfaction compared to biological mothers, but voluntary childfree women had significantly greater life satisfaction. More detailed analyses indicated that internalization of cultural norms only appears to influence the life satisfaction of women with biological children.

The results suggest that it may not simply be motherhood that affects women’s well-being, but rather that women’s internalization of motherhood ideals, particularly when it corresponds with their motherhood status, significantly impacts well-being. Limitations of this study include small cell sizes for some categories of women where additional distinctions may have been useful, such as lesbian or adoptive mothers. Future work should incorporate diverse family forms and expand on the newly named category “double mothers.”

By providing a more nuanced approach to categorizing motherhood status, including identifying double mothers, stepmothers-only, and two groups of childless women, the study added detail that has been overlooked in previous work on well-being.

Migrant workers are often concentrated in segments of the labour market characterised by low-paid and insecure work and which fall outside of the traditional ‘web of rules’ providing workers with protections. Institutional experimentation provides an opportunity to rectify this. This chapter examines the reasons why migrant workers are often subject to exploitation and marginalisation in the labour market. It then analyses the roles of the three main actors with the capacity to protect and improve migrant workers’ labour market position: governments, trade unions and community organisations. It proposes a ‘co-regulation’ approach based on collaborative institutional experimentation between these actors as the most effective way to address the exploitation and marginalisation of migrant workers.

The gender-gap reversal in education could have far-reaching consequences for marriage and family lives in the United States. This study seeks to address the following question: As women increasingly marry men with less education than they have themselves, is the traditional male breadwinner model in marriage challenged?

This study takes a life course approach to examine how educational assortative mating shapes trajectories of change in female breadwinning status over the course of marriage. It uses group-based trajectory models to analyze data from the National Longitudinal Survey of Youth 1979.

The results reveal substantial movement by wives in and out of the primary breadwinner role across marital years and great heterogeneity in female breadwinning trajectories across couples. In addition, educational assortative mating plays a role in shaping female breadwinning trajectories: Compared with wives married to men whose educational levels equal or exceed their own, wives married to men with less education than themselves are more likely to have a continuously high probability of being primary earners and are also more likely to gradually or rapidly transition into primary earners if initially they are not.

This study examines couples’ breadwinning arrangements over an extended period of time and identifies qualitatively distinct patterns of change in female breadwinning that are not readily identifiable using ad hoc, ex ante classification rules. The findings suggest that future research on the economics of marriage and couple relations in families would benefit from a life course approach to conceptualizing couples’ dynamic divisions of breadwinning.
