A Survey of Graduate Education in Community Psychology in Canada

A national survey was conducted to determine current opportunities for graduate education in community psychology in Canada. The results show expanded offerings for academic and field work education in community psychology in the past decade. Also, faculty perceptions of the goals, activities, and adequacy of training in community psychology were obtained. Finally, similarities and differences between graduate education in community psychology in Canada and the U.S. are noted. Issues related to the development of community psychology in Canada are discussed

Ducci on Zm3\mathbb{Z}_m^3 and the Max Period

Let $D(x_1, x_2, ..., x_n)=(x_1+x_2 \;\text{mod} \; m, x_2+x_3 \; \text{mod} \; m, ..., x_n+x_1 \; \text{mod} \; m)$ where $D \in End(\mathbb{Z}_m^n)$ be the Ducci function. The sequence $\{D^k(\mathbf{u})\}_{k=0}^{\infty}$ will eventually enter a cycle. If $n=3$, we aim to establish the longest a cycle can be for a given $m$

IDENTIFYING POLICY RELEVANT VARIABLES FOR REDUCING CHILDHOOD MALNUTRITION IN RURAL MALI

The paper uses OLS and Logit analyses of household survey data to identify and compare determinants of the health and nutritional status of Malian children living in three distinct agricultural production zones (cotton, millet/sorghum, and irrigated rice). These preliminary results suggest that improvements in health center coverage (e.g., reducing the average distance to a health center from 20 to 10 kilometers) and more diversity in complementary foods after six months of age (two or more different foods during a 24 hour period) have the potential to significantly improve standardized height for age scores. Other factors of importance are mother's incomes, prenatal visits, and parents' standardized heights (reflecting either genetic traits or generations of poor nutrition). Recommendations for reducing Mali's high prevalence of malnutrition include the need to raise awareness of the problem among rural populations. Because rural health workers, local administrators, and parents do not recognize malnutrition as a problem, newly empowered decentralized governments will need some external assistance to get the issue on local agendas and identify potential solutions.Food Consumption/Nutrition/Food Safety,

The Period of Ducci Cycles on Z2l\mathbb{Z}_{2^l} for Tuples of Length 2k2^k

Let the Ducci function $D: \mathbb{Z}_m^n \to \mathbb{Z}_m^n$ be defined as $D(x_1, x_2, ..., x_n)=(x_1+x_2 \; \text{mod} \; m, x_2+x_3 \; \text{mod} \; m, ..., x_n+x_1 \; \text{mod} \; m)$. In this paper, we will prove that if $n,m$ are powers of $2$, then repeatedly applying $D$ will eventually result in $(0,0,...,0)$, as well as establish an upper bound for how many iterations it will take for this to happen

AGRICULTURE AND RELATED SECTORS IN THE CILSS COUNTRIES: PAST PERFORMANCE AND STRATEGIC CHOICES FOR THE FUTURE

The document identified five priority areas on which to focus future development plans and projects: 1) human resource development; 2)institutional capacity building; 3) rapid and sustainable development of agricultural production; 4) economic growth and diversification; 5) greater regional integration and ties to the world economy. Recognizing that several of these priorities reached beyond its mandate, CILSS recommended that other more qualified regional organizations (ECOWAS, UEMOA) assume their responsibilities in pursuing these objectives. This paper analyzes the past performance, potential for and challenges facing the agricultural sector in the Sahel, focusing on the factors critical to increasing household income and improving food security in the Sahel. It is divided in four parts.Industrial Organization,

Linkages Between Agricultural Growth and Improved Child Nutrition in Mali

This paper presents the results of the first phase of a project aimed at analyzing the links between agricultural growth in Mali and child nutritional status. The objective of this project is to strengthen these links through applied research and extension. The first phase of the project was designed to generate hypotheses concerning the relationship and review existing data to test these hypotheses, generate new hypotheses and draw policy implications. The second phase of this project will carry out in-depth research to address the critical questions left unanswered in phase I and initiate actions designed to improve these links.food security, food policy, child nutrition, Mali, agricultural growth, Food Consumption/Nutrition/Food Safety, International Development, Downloads July 2008-July 2009: 13, I1,

US Household Demand for Organic Fruit

We estimate US household monthly elasticities of demand for some of the more popular organic fruits. To our knowledge, this is the first US-wide, multi-year analysis of price and income elasticities for various organic fruits. We calculate elasticities of demand for low-income, middle class, and rich income bracket households using three estimation techniques: two econometric methods and one machine learning method (least absolute shrinkage and selection operator (LASSO)). Demand estimates are based on Nielsen scanner data from approximately 60,000 households collected from 2011 to 2013. Generally, we find that own-price conditional and unconditional elasticities of demand for organic fruits are negative. Unconditional elasticity magnitudes tend to be largest in the representative middle-class household. Income elasticities of demand measurements are inconsistent and often statistically insignificant. This finding is consistent with the survey literature finding that many consumers buy organic food for mostly moral or ethical reasons. We run two policy experiments: a 10% subsidy of organic fruits, and a 10% tax on conventional fruits. Our hypothetical policies engender a stronger reaction among the general public than habitual buyers of organic fruit; unconditional purchase and expenditure elasticities are generally larger than conditional purchase and expenditure elasticities. Finally, we find that elasticities measured with the LASSO technique are not radically different than those measured with econometric methods. The most noticeable difference between the two analytical techniques is that LASSO is more likely to find price and income elasticities of demand that indistinguishable from zero, both substantively and statistically

Sprouty2 mediated tuning of signalling is essential for somite myogenesis

Background: Negative regulators of signal transduction cascades play critical roles in controlling different aspects of normal embryonic development. Sprouty2 (Spry2) negatively regulates receptor tyrosine kinases (RTK) and FGF signalling and is important in differentiation, cell migration and proliferation. In vertebrate embryos, Spry2 is expressed in paraxial mesoderm and in forming somites. Expression is maintained in the myotome until late stages of somite differentiation. However, its role and mode of action during somite myogenesis is still unclear. Results: Here, we analysed chick Spry2 expression and showed that it overlaps with that of myogenic regulatory factors MyoD and Mgn. Targeted mis-expression of Spry2 led to inhibition of myogenesis, whilst its C-terminal domain led to an increased number of myogenic cells by stimulating cell proliferation. Conclusions: Spry2 is expressed in somite myotomes and its expression overlaps with myogenic regulatory factors. Overexpression and dominant-negative interference showed that Spry2 plays a crucial role in regulating chick myogenesis by fine tuning of FGF signaling through a negative feedback loop. We also propose that mir-23, mir-27 and mir-128 could be part of the negative feedback loop mechanism. Our analysis is the first to shed some light on in vivo Spry2 function during chick somite myogenesis
