Symbolic correlation integral

This paper aims to introduce the concept of symbolic correlation integral SC that is extensively used in many scientific fields. The new correlation integral SC avoids the noisy parameter 𝜀 of the classical correlation integral, defined by Grassberger and Procaccia (1983 Grassberger, P., Procaccia, I. (1983). Measuring the strangeness of strange attractors. Physica D: Nonlinear Phenomena 9(1–2):189–208.[Crossref], [Web of Science ®] , [Google Scholar]) and extensively used for constructing correlation-integral-based statistics, as in the BDS test. Once the free parameter 𝜀 disappears, it is possible to construct a nonparametric powerful test for independence that can also be used as a diagnostic tool for model selection. The symbolic correlation integral is also extended to deal with multivariate models, and a test for causality is proposed as an example of the theoretical power of the new concept. With extensive Monte Carlo simulations, the paper shows the good size and power performance of symbolic correlation-integral-based tests.     

Mapping Right-Wing Women’s Policy Priorities in Latin America

ABSTRACT

Do right-wing women hold unique policy priorities from that of left-wing women and right-wing men? And do right-wing women legislators represent the priorities of right-wing citizens? Right-wing women share unique gendered socialization experiences with left-wing women, but their ideology informs values and attitudes critical to policy preference formation. Political representation theories suggest that women legislators should hold distinct incentives to represent female constituents. However, institutional theories suggest right-wing women legislators may face different incentives that limit the extent to which they represent right-wing female constituents. To evaluate our expectations, we leverage survey data from the Latin American Public Opinion Project and the Parliamentary Elites of Latin America. We demonstrate how right-wing women citizens differ from left-wing women citizens across a range of policy priorities. Then, we evaluate elite priorities for these same policy issues. We find little evidence for policy priority congruency between women citizens and women legislators on the right.     

Discrimination Experienced by Immigrants,Racialized Individuals,and Indigenous Peoples in Small- and Mid-Sized Communities in Southwestern Ontario

We investigate discrimination experiences of (1) immigrants and racialized individuals, (2) Indigenous peoples, and (3) comparison White non-immigrants in nine regions of Southwestern Ontario containing small- and mid-sized communities. For each region, representative samples of the three groups were recruited to complete online surveys. In most regions, over 80 percent of Indigenous peoples reported experiencing discrimination in the past 3 years, and in more than half of the regions, over 60 percent of immigrants and racialized individuals did so. Indigenous peoples, immigrants and racialized individuals were most likely to experience discrimination in employment settings and in a variety of public settings, and were most likely to attribute this discrimination to racial and ethnocultural factors, and for Indigenous peoples also their Indigenous identity. Immigrants and racialized individuals who had experienced discrimination generally reported a lower sense of belonging and welcome in their communities. This association was weaker for Indigenous peoples. The findings provide new insight into discrimination experienced by Indigenous peoples, immigrants and racialized individuals in small and mid-sized Canadian communities, and are critical to creating and implementing effective anti-racism and anti-discrimination strategies.     

Marriage: for love,for money…and for time?

Married couples enjoy meaningful economies in time, often choosing to specialize where one spouse focuses on market work and the other on household production and childcare. Using data from the American Time Use Survey 2003–2008, I estimate significant marriage effects upon time use. Most married women gain 33–34 min of leisure each weekday when compared to single women. While marriage does not lead to more leisure for husbands, it allows them to allocate time away from home and towards market work. Lower-income couples work more at home and for pay, and spend less time in leisure than their single counterparts. The temporal and financial gains from marriage for most people are inconsistent with its declining prevalence.     

Evidence‐based Management in Practice: Opening up the Decision Process,Decision‐maker and Context

Evidence‐based management (EBM) has been subject to a number of persuasive critiques in recent years. Concerns have been raised that: EBM over‐privileges rationality as a basis for decision‐making; ‘scientific’ evidence is insufficient and incomplete as a basis for management practice; understanding of how EBM actually plays out in practice is limited; and, although ideas were originally taken from evidence‐based medicine, individual‐situated expertise has been forgotten in the transfer. To address these concerns, the authors adopted an approach of ‘opening up’ the decision process, the decision‐maker and the context (Langley et al. ( 1995 ). ‘Opening up decision making: the view from the black stool’, Organization Science, 6, pp. 260–279). The empirical investigation focuses on an EBM decision process involving an operations management problem in a hospital emergency department in Australia. Based on interview and archival research, it describes how an EBM decision process was enacted by a physician manager. It identifies the role of ‘fit’ between the decision‐maker and the organizational context in enabling an evidence‐based process and develops insights for EBM theory and practice.     

A Preliminary Comparison Study of Online and Face-to-Face Counseling: Client Perceptions of Three Factors

This preliminary study examined the similarities and differences between online and face-to-face counseling with regard to general mental health, working alliance, and social presence. Participants included 50 current counseling clients (37 face-to-face, 13 online) who all were recruited through online mediums. Results indicated that online counseling clients perceived a significantly stronger working alliance on the total Working Alliance Inventory-Short Form as well as the Goal subscale than did those who received face-to-face only counseling. No significant differences existed between the groups on general mental health or social presence. These results suggest that a more controlled study with a larger sample might find that a strong working alliance can be developed through online counseling.     

Mindfulness in financial literacy

ABSTRACT

Financial education is becoming imperative in a society that has pitfalls for unwary consumers. To ensure effectiveness, educational strategies must take into consideration the readiness of consumers to learn the curriculum. Behavioral economics highlights the obstacles that educators face in promoting financial efficacy. Such obstacles include envy, fear, greed, and other all too familiar human failings. One innovative model, mindfulness, provides insight into the human dynamics of personal financial behaviors. This article ties together financial education, mindfulness techniques, and transtheoretical stages of readiness. The impact of gradually introduced educational tasks is presented with an eye toward clients’ stages of readiness, and mindfulness addresses the emotional burdens of altering a financially profligate lifestyle.     

Quality and the 2010 Census

The U.S. Census Bureau has a long tradition of evaluating the results of its censuses. This paper presents evaluation results from the 2010 Census, comparing them to earlier results. The paper discusses net coverage at the national and state level, as well as by age, sex, race, and ethnic group. It discusses components of error, including estimated number missed and counted in error. It also presents data on whole-person and item imputation.
