Counselors, psychologists, and evaluators of intervention programs for youth increasingly view the promotion of connectedness as an important intervention outcome. When evaluating these programs, researchers frequently test whether the treatment effects differ across gender and ethnic or racial groups. Doing so necessitates the availability of culturally and gender-invariant measures. We used t...

This article is based on five lectures the author gave during the summer school, Interactions between Homotopy Theory and Algebra, from July 26–August 6, 2004, held at the University of Chicago, organized by Lucho Avramov, Dan Christensen, Bill Dwyer, Mike Mandell, and Brooke Shipley. These notes introduce basic concepts concerning local cohomology, and use them to build a proof of a theorem Gr...

We propose several connectedness measures built from pieces of variance decompositions, and we argue that they provide natural and insightful measures of connectedness among financial asset returns and volatilities. We also show that variance decompositions define weighted, directed networks, so that our connectedness measures are intimately-related to key measures of connectedness used in the ...

IMPLEMENTATION This reprint corresponds to the book-chapter " Algorithms for the detection of connectedness and their neural implementation " , Connectedness is one of the most important grouping criteria that allow the visual system to segregate objects from each other and from the background. We review algorithms for the detection of connectedness from a physiological point of view. Connected...

a r t i c l e i n f o This study compared perceptions of school connectedness to traditional community schools and residential treatment center (RTC) schools for youths between the ages of 12 and 18 receiving treatment within two RTCs. The influence of gender, report card grades, and engagement in treatment were also examined in relation to school connectedness in the RTC schools. Findings indi...

School connectedness is an important protective factor for adolescent risk-taking behaviour. This study examined a pilot version of the Skills for Preventing Injury in Youth (SPIY) programme, combining teacher professional development (PD) for increasing school connectedness (connectedness component) with a risk and injury prevention curriculum for early adolescents (curriculum component). A pr...

Using a connectedness-measurement technology fundamentally grounded in modern network theory, we measure real output connectedness for a set of six developed countries, 1962-2010. We show that global connectedness is sizable and time-varying over the business cycle, and we study the nature of the time variation relative to the ongoing discussion about the changing nature of the global business ...

Social connectedness derived from Facebook is associated with positive outcomes such as better psychological health wellbeing. Yet to date, little is known about the construct of Facebook social connectedness. The aim of this study was to draw on existing studies of Facebook use to investigate what might predict social connectedness stemming from Facebook use. Participants (N = 326, age range 1...

Subjective well-being theories of goal approach and value-as-a-moderator were applied to examine the role of importance of social connectedness on the relationship between social connectedness and subjective well-being in a community sample of 204 Korean immigrants. It was hypothesized that social connectedness in ethnic and mainstream society is a stronger predictor of well-being to immigrants...
