Exploratory data structure comparisons: three new visual tools based on principal component analysis

Datasets are sometimes divided into distinct subsets, e.g. due to multi-center sampling, or to variations in instruments, questionnaire item ordering or mode of administration, and the data analyst then needs to assess whether a joint analysis is meaningful. The Principal Component Analysis-based Data Structure Comparisons (PCADSC) tools are three new non-parametric, visual diagnostic tools for investigating differences in structure for two subsets of a dataset through covariance matrix comparisons by use of principal component analysis. The PCADCS tools are demonstrated in a data example using European Social Survey data on psychological well-being in three countries, Denmark, Sweden, and Bulgaria. The data structures are found to be different in Denmark and Bulgaria, and thus a comparison of for example mean psychological well-being scores is not meaningful. However, when comparing Denmark and Sweden, very similar data structures, and thus comparable concepts of well-being, are found. Therefore, inter-country comparisons are warranted for these countries.     

Grandparents raising grandchildren: negotiating the complexities of role‐identity conflict

The purpose of this qualitative study was to better understand the experience of grandparents who are raising their grandchildren in New South Wales, Australia. In‐depth interviews were conducted with 34 grandparents and their narratives transcribed and studied using paradigmatic analysis to reveal common themes among the stories told. Identity theory further informed the discussion of these findings. Woven throughout the grandparent narratives is a story of paradox – of experience simultaneously made up of pain/pleasure, myth/reality, inclusion/exclusion, being deserving/undeserving, visible/invisible and voiced/silenced. The findings signal a significant role‐identity conflict for grandparents who are parenting grandchildren. This study points to the need for policy and practice that more closely reflects the complexity of experience associated with the grandparent‐as‐parent role.     

Non‐Parametric Estimation of the Conditional Distribution of the Interjumping Times for Piecewise‐Deterministic Markov Processes

This paper presents a non‐parametric method for estimating the conditional density associated to the jump rate of a piecewise‐deterministic Markov process. In our framework, the estimation needs only one observation of the process within a long time interval. Our method relies on a generalization of Aalen's multiplicative intensity model. We prove the uniform consistency of our estimator, under some reasonable assumptions related to the primitive characteristics of the process. A simulation study illustrates the behaviour of our estimator.     

Nowcasting GDP in Real Time: A Density Combination Approach

In this article, we use U.S. real-time data to produce combined density nowcasts of quarterly Gross Domestic Product (GDP) growth, using a system of three commonly used model classes. We update the density nowcast for every new data release throughout the quarter, and highlight the importance of new information for nowcasting. Our results show that the logarithmic score of the predictive densities for U.S. GDP growth increase almost monotonically, as new information arrives during the quarter. While the ranking of the model classes changes during the quarter, the combined density nowcasts always perform well relative to the model classes in terms of both logarithmic scores and calibration tests. The density combination approach is superior to a simple model selection strategy and also performs better in terms of point forecast evaluation than standard point forecast combinations.     

Public meetings as sources of citizen input: Comparing attendees with citizens at large

Although public meetings are the most frequently used method for obtaining citizen input into public decision-making, there is little systematic evidence comparing attendees with citizens at large. This paper addresses this gap in the literature by analyzing results from a series of public meetings and a random-sample telephone survey. The public meetings and telephone survey were conducted in Hillsborough County, Florida to obtain citizen input for the purpose of establishing spending priorities for more than $39 million in federal block grant funds. Findings include representation at public meetings on a number of factors, including race, Hispanic ethnicity, and low-income status. Attendees favor redistributive activities more often than citizens at large; however, both attendees and the general public agree on the importance of funding activities serving certain vulnerable populations, including seniors, persons with disabilities, and victims of domestic violence.     

Location of Public Goods and the Calculus of Voting: The Seattle Monorail Referendum*

Objectives. In this article we explore how the geographic location of a proposed public good on the ballot in a local referendum influences voting turnout. We argue that voters who live farther away from the good, and are thus likely to bear the cost of the good but have no access to it, would be more motivated to turn out in the election. Drawing on the cost‐orientation hypothesis, or negativity effect, “that people are more strongly motivated to avoid losses than to approach gains,” we expect these voters to derive higher expressive benefits from the act of voting relative to those of voters located closer to the good. Methods. We examine voting turnout in the 2002 referendum in the City of Seattle on the proposed construction of a monorail. We conduct our study at the precinct level using spatial tools of analysis. We evaluate the effect of accessibility on turnout by means of a curvilinear model that incorporates demographic and political variables. Results. We find that voting turnout is determined partly by accessibility. Turnout is higher in precincts located farther away from the monorail line than in precincts located relatively closer to the line. Partisanship conditions this effect. Conclusions. This study provides tentative support for linking voter turnout to the negativity effect via expressive benefits. Voters' location in relation to a public good may affect directly their political behavior by means of their perceived net gains or losses from the good.     

Gendering of success: fashion designers in designer stories in the Finnish lifestyle magazine Gloria*

Fashion journalism is part of the fashion system that legitimizes and reproduces the creativity, celebrity status, and symbolic power of fashion designers. This article examines the gendering of the success of fashion designers in designer stories in the Finnish lifestyle magazine Gloria. The material consists of 21 stories about designers published in 2013–2014. They are analyzed by applying a multimodal close reading that takes into account the dialogic relationship between written text and images. The analysis highlights the gendered representation of success: male designers emerge differently from women designers as glamorous personas and successful professionals. First, male designers are related to a grand tradition and presented as designers in the own right, whereas women designers are mostly depicted as continuers of a man’s work or a family business; second, many women designers are presented as designers of one particular hit item; third, women’s designership is presented as work and business instead of genuine creative art; and fourth, women designers are presented as more approachable and communicative human beings than men both in verbal and in visual expression. Hence, success is produced in a way that emphasizes the male designers’ visionary characteristics and decreases the grandeur of the women’s designership.     

“What Will My Friends Think?” Social Consequences for Danish Victims of Sexual Assaults in Peer Groups

Being exposed to sexual assaults has numerous psychological and social consequences, which may interfere with the adolescent’s still-ongoing development. This article focuses on social consequences for adolescents exposed to sexual assault by someone from their peer group.

Participants were 148 in number and 15–18 year olds (M = 16.34 years, 90.5% female) from Centre for Victims of Sexual Assault’s “Youth Programme.”

A mixed methods design combined extensive survey data collected from the 148 adolescents and five case stories. Almost half of the assaults (47.4%) were committed by someone from the victim’s social circle who was not a family member. Only 30.5% of these victims reported the assault to the police. Fear of social consequences was the main reason for not reporting. The majority of the participants described failure to thrive in school in the aftermath of the assault, for example, because the assailant attended the same school. Result furthermore showed how social relations can be complicated due to an assault and subsequent reactions, which can result in isolation for the victim and exclusion from their peer group.

Sexual assaults in peer groups have great impact on the victim’s well-being. Understanding and support from peers is of the utmost importance. Implications for practice are discussed.
