Stable diquark matter ?

Two-quark correlations ({\it diquarks}) may play an important role in hadronic physics, particularly near the deconfinement point. This opens the possibility of a net energy gain by means of a (non-perturbative) quark pairing effect, perheps up to stabilize diquark droplets. We address in this work the possibility of a self-bound, stable state of bulk diquark matter.Comment: 10p. PlainTeX, 2 Figures available upon request. IAG-USP Report No 3

IN THE FOOTSTEPS OF CRISTO OBRERO: CHILE'S YOUNG CATHOLIC WORKERS MOVEMENT IN THE NEIGHBORHOOD, FACTORY, AND FAMILY, 1946-1973

This dissertation examines the history of the Chilean Young Catholic Workers movement (JOC) from its founding in 1946 until the 1973 coup that almost completely destroyed it. The study explores how the JOC, a specialized branch of Catholic Action, formed a significant link in the widespread mobilization of the working classes in postwar Chile, where the movement achieved a depth and influence unmatched anywhere else in Latin America. The JOC reached its peak in the 1950s in the country's booming industrial centers, with the movement's many large-scale events, activities, and campaigns attracting thousands from across the country, but it continued to have a considerable presence in working-class neighborhoods through the politically turbulent 1960s and early 70s. Fomenting a social and political consciousness intertwined with Catholic religiosity, the JOC served as a launching pad for local community activism as well as involvement in political parties and unions. Furthermore, JOC activists' commitment to social justice forged a path for the "popular" or "liberationist" Church that became a cornerstone of resistance to the Pinochet dictatorship.While connecting the JOC to Chile's broader social and political history, this dissertation focuses attention on how the ideologies and policies of a reformist Church worked themselves out on the ground. Drawing on both oral and written sources, it emphasizes the movement's significance for the young women and men living in Santiago's densely populated slums and working in the city's factories, workshops, and commercial centers. In particular, JOC activists' personal stories reveal how religion, class, and gender intersected in the movement to empower female workers. Despite being embedded in a patriarchal Church structure, the JOC's social Catholic discourse led working-class women to carve out a unique space for social activism and leadership that deeply influenced female activists' expectations regarding domestic relations and motherhood. At the same time, the JOC's focus on workers and workplace issues also made it attractive to young men, who traditionally shied away from Church participation at the parish level. In a movement in which women had equal authority, this participation provoked a subtle shift in men's perceptions of male power and dominance

Critical Thinking in Occupational Therapy Education: A Systematic Mapping Review

Critical thinking is a component of occupational therapy education that is often intertwined with professional reasoning, even though it is a distinct construct. While other professions have focused on describing and studying the disciplinary-specific importance of critical thinking, the small body of literature in occupational therapy education on critical thinking has not been systematically analyzed. Therefore, a systematic mapping review was conducted to examine, describe, and map existing scholarly work about critical thinking in occupational therapy education. Inclusion/exclusion criteria were set, database searches conducted, and 63 articles identified that met criteria for full review based on their abstracts. Thirty-five articles were excluded during full review, leaving 28 articles for analysis and coding using a data extraction tool. Eleven articles (39%) had a primary focus of critical thinking, and of those 11 articles, the majority were about instructional methods. Qualitative inquiry (n = 9) was the most frequently used method to examine critical thinking among the study full sample (N = 28). Four themes emerged: 1) critical thinking is a process with varied outcomes; 2) learner aptitude is essential for developing critical thinking; 3) critical thinking can be facilitated through various methods; and 4) critical thinking underpins other important constructs in occupational therapy. Needs that were identified were that critical thinking is best intentionally threaded across a curriculum with outcomes in mind; and more studies examining critical thinking in occupational therapy education, employing diverse designs, are needed

Creating a Charrette Process to Ignite the Conversation on Equity and Inclusion

The gaps in graduation and retention rates between ethnic and gender groups continue to be a foremost area of focus at Borough of Manhattan Community College (BMCC), The City University of New York (CUNY). Equity and inclusion is also a critical concern as it relates to faculty and staff. At BMCC, a college-wide initiative, Designing for Success, is seeking to improve declining retention and graduation rates. At its core is the question, “Have we designed our operations to produce these results?” The answer is, “Yes”. BMCC’s Designing for Success strategic planning process seeks to re-design administrative processes and teaching in an effort to eradicate these gaps through efforts which include a community-wide discussion and action planning on equity and inclusion inspired by the charrette process. The charrette creates small groups that meet on more than one occasion to identify critical barriers to addressing equity and inclusion and develops action plans for addressing these barriers from stakeholders at all levels of an organization. This paper proposes that public scholarship is at the core of the charrette process, that it is uniquely appropriate for the higher education environment and moves the community from a “discussion” of the barriers to fully engaging the entire college community in meaningful action-oriented strategic planning

Association between Parent and Child Dietary Sodium and Potassium Intakes as Assessed by 24-h Urinary Excretion

The aim of this study was to assess the association between parent and child sodium (Na) and potassium (K) intake as assessed by 24-h urinary excretion (24hUE). Primary school children and their parent(s) provided one 24-h urine sample and information on cooking and children\u27s discretionary salt use. Valid urine samples were provided by 108 mothers (mean age 41.8 (5.1) (SD) years, Na 120 (45) mmol/day) (7.0 g/day salt equivalent) and 40 fathers (44.4 (4.9) years, Na 152 (49) mmol/day (8.9 g/day salt), and 168 offspring (51.8% male, age 9.1 (2.0) years, Na 101 (47) mmol/day (5.9 g/day salt). When adjusted for parental age, child age and gender a 17 mmol/day Na (1 g/day salt) increase in mother\u27s 24hUE was associated with a 3.4 mmol/day Na (0.2 g/day salt) increase in child\u27s salt 24hUE (p = 0.04) with no association observed between father and child. Sixty-seven percent of parents added salt during cooking and 37% of children added salt at the table. Children who reported adding table salt had higher urinary excretion than those who did not (p = 0.01). The association between mother and child Na intake may relate to the consumption of similar foods and highlights the importance of the home environment in influencing total dietary sodium intake

Pure-glue hidden valleys through the Higgs portal

We consider the possibility that the Higgs boson can act as a link to a hidden sector in the context of pure-glue hidden valley models. In these models the standard model is weakly coupled, through loops of heavy messengers fields, to a hidden sector whose low energy dynamics is described by a pure-Yang-Mills theory. Such a hidden sector contains several metastable hidden glueballs. In this work we shall extend earlier results on hidden valleys to include couplings of the messengers to the standard model Higgs sector. The effective interactions at one-loop couple the hidden gluons to the standard model particles through the Higgs sector. These couplings in turn induce hidden glueball decays to fermion pairs, or cascade decays with multiple Higgs emission. The presence of effective operators of different mass dimensions, often competing with each other, together with a great diversity of states, leads to a great variability in the lifetimes and decay modes of the hidden glueballs. We find that most of the operators considered in this paper are not heavily constrained by precision electroweak physics, therefore leaving plenty of room in the parameter space to be explored by the future experiments at the LHC.Comment: 44 pages, 16 figures.

24-h urinary sodium excretion is associated with obesity in a cross-sectional sample of Australian schoolchildren

Emerging evidence indicates that dietary Na may be linked to obesity; however it is unclear whether this relationship is independent of energy intake (EI). The aim of this study was to assess the association between Na intake and measures of adiposity, including BMI z score, weight category and waist:height ratio (WHtR), in a sample of Australian schoolchildren. This was a cross-sectional study of schoolchildren aged 4-12 years. Na intake was assessed via one 24-h urine collection. BMI was converted to age- and sex-specific z scores, and WHtR was used to define abdominal obesity. In children aged ≥8 years, EI was determined via one 24-h dietary recall. Of the 666 children with valid urine samples 55 % were male (average age 9·3 (sd 1·8) years). In adjusted models an additional 17 mmol/d of Na was associated with a 0·10 higher BMI z score (95 % CI 0·07, 0·13), a 23 % (OR 1·23; 95 % CI 1·16, 1·31) greater risk of being overweight/obese and a 15 % (OR 1·15; 95 % CI 1·09, 1·23) greater risk of being centrally obese. In the subsample of 8-12-year-old children (n 458), adjustment for EI did not markedly alter the associations between Na and adiposity outcomes. Using a robust measure of daily Na intake we found a positive association between Na intake and obesity risk in Australian schoolchildren, which could not be explained by total energy consumption. To determine whether this is a causal relationship, longitudinal studies, with high-quality measures of Na and EI, are required

Anderson's ethical vulnerability: animating feminist responses to sexual violence

Pamela Sue Anderson argues for an ethical vulnerability which “activates an openness to becoming changed” that “can make possible a relational accountability to one another on ethical matters”. In this essay I pursue Anderson’s solicitation that there is a positive politics to be developed from acknowledging and affirming vulnerability. I propose that this politics is one which has a specific relevance for animating the terms of feminist responses to sexual violence, something which has proved difficult for feminist theorists and activists alike. I will demonstrate the contribution of Anderson’s work to such questions by examining the way in which “ethical vulnerability” as a framework can illuminate the intersectional feminist character of Tarana Burke’s grassroots Me Too movement when compared with the mainstream, viral version of the movement. I conclude by arguing that Anderson’s “ethical vulnerability” contains ontological insights which can allay both activist and academic concerns regarding how to respond to sexual violence
