Corner Store and Commuting Patterns of Low-Income, Urban Elementary School Students

Schools are often a setting to implement nutrition-based pediatric obesity prevention programs. However, when there has been considerable focus on the school environment in the context of childhood obesity, less is known about the environments around the school, particularly in low-income, urban neighborhoods. The purpose of this study was to assess students’ corner store and commuting habits before and after school in a low-income, urban environment. 

This was a cross-sectional study. Participants were 702 4th - 6th graders from 10 K-8 public schools where 82.1% ± 7.4% of children qualified for free or reduce-priced meals. Participants were surveyed about their corner store and commuting habits by using a 16-item questionnaire. Both height and weight were measured twice and the average of each was used and Body Mass Index (BMI) as well as BMI z-scores and BMI percentiles based on age and sex were calculated for each student. Besides, student’s demographic information was self-reported. 

The results showed that the majority of 4th - 6th grade urban students shopped in corners stores either in the morning (57.4%) or in the afternoon (58.5%). Nearly half (44.8%) reported shopping and purchasing in both the morning and the afternoon. Children reported spending approximately $2.00 per corner store visit. Approximately two-thirds of children reported that they walked to or from school. Children who walked to school frequented corner stores more than those using other commuting methods. Relative weight status was not related to corner store or commuting patterns. 

In short, many low-income children purchase food at corner stores before and/or after school, making corner stores an important target for public health nutrition. While many children walk to school, those are more likely to frequent corner stores. Neither corner store nor commuting pattern is associated with relative weight. Further research should also include a greater range of age groups to better understand if these patterns vary by age.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...
