Evaluation of the What's Real: Myths & Facts about Marriage Curriculum: Differential Impacts of Gender*

ABSTRACT

What’s Real is a high school marriage education curriculum designed to teach students how to develop healthy relationships and marriages. This study evaluated the effectiveness of this curriculum with 206 high school students who were in either the What’s Real group or a control group. Findings suggest that the curriculum increases knowledge of healthy relationship concepts, positively impacts attitudes related to students’ willingness to be involved in pre- and postmarital counseling, and increases students’ attitudes toward cohabitation avoidance. Implications for further development of the curriculum and other implications for practitioners and policymakers are discussed.     

Homeless Affiliation,Location, and Sender Address in Return of Lost Letters

A field study used 1008 “lost letters” to test the hypotheses that the differences in returned responses would be attributable to the addressee (i.e., ending homelessnesscontrol or preventing it among youth, veterans, and lesbians) and especially to a socially deviant addressee, that cultural differences between distribution locations might influence returned responses of lost letters, and that sender address (i.e., urban, rural, control) would also influence returned responses. Both addressees’ affiliations and distribution location were associated with returned responses, with the lowest rates being for the Prevent Lesbian Homelessness Program affiliate overall and for the city of Pensacola, respectively. Antigay prejudice toward a deviant group may still be strong even when a helping act can be performed without intimate contact involving members of a deviant group. Neither distribution location nor the sender or return address conditions were associated with different returned responses. Further testing of the lost letter technique, as a measure of public response, may be warranted.     

Managing Children’s Friendships Through Interparental Relationships: Roles of Ethnicity and Friendship Context

Twenty African American and European American mothers of fourth‐grade students reflected on strategies for managing children’s friendships maintained across a variety of contexts. Ethnicity differentially located families within specific social contexts that yielded children’s friendships, then informed social processes as they unfolded within these contexts. Maternal knowledge concerning children’s friendships developed as a function of the types of relationships formed among parents encountered within different settings. Findings suggest that interparental relationships represent a key source of information about children’s friendships. Yet, maternal opportunities to establish such relationships differ on the basis of both ethnicity and the nature of contexts in which children’s friendships are maintained.     

Estimating the Number of Block Boundaries from Diagonal Blockwise Matrices Without Penalization

In computational biology, numerous recent studies have been dedicated to the analysis of the chromatin structure within the cell by two‐dimensional segmentation methods. Motivated by this application, we consider the problem of retrieving the diagonal blocks in a matrix of observations. The theoretical properties of the least squares estimators of both the boundaries and the number of blocks are investigated. More precisely, the contribution of the paper is to establish the consistency of these estimators. A surprising consequence of our results is that, contrary to the one‐dimensional case, a penalty is not needed for retrieving the true number of diagonal blocks. Finally, the results are illustrated on synthetic data.     

A cloud-based spatial-temporal inventory for sustainable urban soil management

Spatial and temporal databases that integrate urban tree inventories and soil quality information are needed for modern-day sustainable urban forest management. The objective of this study was to demonstrate the usefulness of low-cost and widely-available technology, such as global positioning system (GPS)–enabled cameras to photo-document sites and cloud-based products and services (Google Picasa and Fusion Tables), to aid in developing sustainable street tree management programs. Google Fusion Tables provide a cloud platform to store, share and map urban tree and soil data over time using internet connected computers, tablets or mobile devices. Although indicators of urban soil quality and best methods to assess it are not yet standardized, we demonstrate here promising indicators that are both useful and easy to incorporate into spatial and temporal databases of trees managed in urban environments. By utilizing technology, we demonstrate that site-specific urban soil quality indicators can be used together with readily-available soil rating systems specific to different plant types as a means to better evaluate and manage conditions for optimal street tree growth and health.     

Religion as nationalism: the religious nationalism of American Christian Zionists

The term ‘religious nationalism’ is often theorized, at worst as antithetically conjunctive where religion is defined as the allegiance to God and nationalism is the allegiance to the nation, and at best as instrumental. I argue here that this fusion of religion and nationalism takes place most convincingly if we understand religion as adherent performance rather than solely as a theological container of tenants. I illustrate this through American Christian Zionist performances and discourses regarding their self-imagined identity as being in a national diaspora for Israel. I argue this religious nationalism is possible because Christian Zionist performances of a national allegiance to Israeli Jews are grounded in an apocalyptic narrative of the future.     

HOUSEHOLD FINANCES,INCOME SHOCKS,AND FAMILY SEPARATION IN BRITAIN

We examine the effect of household financial indebtedness on the incidence of partnership dissolution using a large survey of families with children in Britain. We use detailed data on household finances to provide a robust statistical analysis of the relationship between indebtedness and partnership dissolution and to avoid the potential simultaneity of financial and psychological health responses that arise when using self‐reported data on the extent of household “financial problems.” We examine whether the data provide any support for the “economic” models of divorce and separation developed by Gary Becker and his colleagues.

Weighted Poisson and Semiparametric Kernel Models Applied to Parasite Growth

This work deals with some parametric and semiparametric modeling approaches for count data distributions related to development of spiraling whitefly which is an insect pest collected in Brazzaville, Republic of Congo. In this study, the count data distributions are assumed to be modified Poisson probability mass functions. For the discrete semiparametric associated kernel estimator investigated, its almost sure consistency and asymptotic normality are shown under some asumptions. Some weighted Poisson models (WPD) are applied in comparison with the semiparametric approach for finite samples characterizing the growth of spiraling whitefly. Finally, the discrete semiparametric estimation is simple and effective for estimating any count distribution while WPD are practically more meaningful.     

An adaptive approach to Langevin MCMC

We consider a class of adaptive MCMC algorithms using a Langevin-type proposal density. We state and prove regularity conditions for the convergence of these algorithms. In addition to these theoretical results we introduce a number of methodological innovations that can be applied much more generally. We assess the performance of these algorithms with simulation studies, including an example of the statistical analysis of a point process driven by a latent log-Gaussian Cox process.
