Encontrando la Comida Saludable: Identifying Food Access Barriers for the Adams County, Pennsylvania Latino Community

Overwhelming research indicates that recent national trends in U.S. food systems have led to the increased prevalence of processed foods and associated diet-related diseases. The effects of unhealthy diets have been distributed unevenly across the country’s socioeconomic and ethnic groups. Certain socioeconomic and ethnic groups face greater geographic, financial and cultural barriers to healthy food access. In Adams County, Pennsylvania, Latinos comprise 5.6% of the population, making them the county’s largest minority group, yet little is known about the food access barriers they face. In this study, we used a combination of surveys and focus groups with Latino residents and personal interviews with community leaders to identify the geographic, financial, and cultural barriers to food access for the county’s Latino community. We found that, though geographic and financial barriers had little effect on the community’s access to healthy food, cultural barriers presented a significant obstacle that needs to be addressed. We hope this study will inform the Adams County Food Policy Council in proposing policy measures that address specific food access issues in the county

Domestic tourism and regional inequality in Brazil

This paper analyzes the consumption patterns of tourists coming from different domestic origins and choosing other domestic destinations in Brazil, in terms of expenditure level and composition. We also look at the different alternatives of financing tourist expenditures and their implications for the net multipliers in an integrated framework. We use survey data for domestic tourism in Brazil to consolidate an interregional matrix of expenditures by tourists and then use an interregional input-output system for Brazil to compute the tourism multiplier effects based on alternative hypotheses for the sources of financing of expenditures by tourists. The results are analyzed, and their implications for regional inequality in the country are discussed

Auslander Systems

The authors generalize the dynamical system constructed by J. Auslander in 1959, resulting in perhaps the simplest family of examples of minimal but not strictly ergodic systems. A characterization of unique ergodicity and mean-L-stability is given. The new systems are also shown to have zero topological entropy and fail to be weakly rigid. Some results on the set of idempotents in the enveloping semigroup are also achieved

Field behavior of an Ising model with aperiodic interactions

We derive exact renormalization-group recursion relations for an Ising model, in the presence of external fields, with ferromagnetic nearest-neighbor interactions on Migdal-Kadanoff hierarchical lattices. We consider layered distributions of aperiodic exchange interactions, according to a class of two-letter substitutional sequences. For irrelevant geometric fluctuations, the recursion relations in parameter space display a nontrivial uniform fixed point of hyperbolic character that governs the universal critical behavior. For relevant fluctuations, in agreement with previous work, this fixed point becomes fully unstable, and there appears a two-cycle attractor associated with a new critical universality class.Comment: 9 pages, 1 figure (included).

ADO-Tutor: Intelligent Tutoring System for leaning ADO.NET

This paper describes an Intelligent Tutoring System for helping users with ADO.NET called ADO-Tutor. The Intelligent Tutoring System was designed and developed using (ITSB) authoring tool for building intelligent educational systems. The user learns through the intelligent tutoring system ADO.NET, the technology used by Microsoft.NET to connect to databases. The material includes lessons, examples, and questions. Through the feedback provided by the intelligent tutoring system, the user's understanding of the material is assessed, and accordingly can be guided to different difficulty level of exercises and/or the lessons. The Intelligent Tutoring System was evaluated by a group of users and the results were more than satisfactory in terms of the quality of the material and the design of the system

Trust, membership in groups, and household welfare

This paper explores the relationship between group membership and trust. Specifically, the authors examine (1) the importance of trust in the decision to join groups, (2) the subsequent ability of groups to generate trust, and (3) the influence of group membership and trust on a measure of well-being, per capita household income. They use longitudinal data from KwaZulu-Natal Province, South Africa, allowing them to control for potential simultaneity and measurement-error problems in the estimation. They disaggregate groups into financial and nonfinancial and “trust in people” by type of agent or actor. They can thus examine whether different types of trust are important for participating in different types of groups and whether different types of group participation are important for generating different types of trust. The research finds that (1) trust in local agents is an important determinant of membership in financial groups but not for membership in nonfinancial groups, (2) membership in both types of groups generates trust in nonlocal agents but not local agents, and (3) membership in financial and nonfinancial groups leads to higher well-being. The first two results suggest that financial groups serve a role in expanding the radius of trust, while the first and third results suggest a role for trust in improving well-being.Community participation South Africa. ,Financial institutions South Africa. ,Trust. ,Group membership. ,
