Characterizing Logistics Operations Within a Federal Staging Area for Hurricane Response: A Qualitative Analysis of Federal, State and Local Perspectives
A successful deployment of logistics operations following a disaster is a collective contribution of federal, state, and local entities to ascertain an efficient and effective response. This research analyzes data from interviews with disaster response logistics experts from these entities. The objective is to investigate the information sources and planning processes used in these organizations to plan vehicle routes for critical resource deliveries to impacted areas. Special attention is directed to the impacts of incomplete knowledge of infrastructure status, such as road disruptions due to debris or flooding. Supported by both qualitative and quantitative evidence, the study finds that incomplete knowledge of infrastructure status poses serious critical transportation risks such as delivery delays in disaster relief distribution. This research reveals both similarities and differences in logistical decision-making among these organization types and emphasizes the need for improved information sharing and coordination among emergency response organizations. The findings of this research are expected to guide future initiatives aimed at disaster relief routing thereby enhancing emergency response capabilities and outcomes
Parent Involvement and Student Achievement in the Gulf Cooperation Council Countries: Evidence from PIRLS 2016 Data
Numerous studies have shown that parent involvement has a significant influence on student achievement. However, most of these studies have been conducted in western Europe and North America. In the Gulf Cooperation Council region, we find that quantitative research that targeted parents’ behavior is limited. In order to design efficient parent engagement programs and family policies, we need to understand how parents interact with their children’s education in this area. Data from PIRLS is the only open-access data that allows us to study parent involvement by using a large sample that may reveal parents' behavior patterns. This work investigates elements of parent involvement addressed in the parent questionnaire of PIRLS and studies their relationship to student reading achievement. The results showed a positive influence of parents’ practice of educational activities and their educational expectation on their children's achievement; and a negative association between the later and parents’ help with homework. Implications are discussed in the perspective of the social context in the GCC countries
Effects of Bone Morphogenetic Protein-2 and Parathyroid Hormone-Related Peptide on Collagen XI During Skeletal Development
Long bones develop via endochondral ossification, a process in which cartilage precedes bone. During endochondral ossification prechondrogenic cells undergo proliferation and apoptose as cells of the periosteum differentiate into bone. The process of endochondral ossification is regulated by a group of endocrine as well as paracrine molecules that includes bone morphogenetic protein-2 (BMP-2) and parathyroid hormone-related peptide (PTHrP). Collagens are extracellular matrix molecules that are present in a spatiotemporal manner during endochondral ossification. Collagen XI alpha 1 (Col11a1) is a minor fibrillar collagen that is alternatively spliced during development and can result in up to eight different spliceforms. During endochondral ossification Col11a1 spliceforms have a distinct expression profile in the growing long bone. The significance of the different spliceforms has not been characterized. Here, I studied the effects of BMP-2 and PTHrP on the expression of Col11a1 in pre-chondrogenic mouse ATDC5 and pluripotent mouse C2C12 cells. I also investigated the role of different Col11a1 spliceforms in BMP-2-mediated C2C12 osteoblast differentiation. My results suggest a role for BMP-2 in regulating Col11a1 splicing and expression that includes the induction of exons 6A, 7, and 8. Further I show that while PTHrP alone did not affect Col11a1 expression, when combined with BMP-2, PTHrP was able to diminish BMP-2-induced Col11a1 expression. In addition, Col11a1 NTD[p6b-7] reduced BMP-2 activity in C2C12 cells while Col11a1 NTD[p7] did not have any significant effects. Col11a1 NTD[p6b-7] also reduced the expression of alkaline phosphatase and collagen 1 alpha 1 and increased the expression of Runx2 and osteocalcin while NTD[p7-8] induced the expression of osteocalcin, Runx2, and collagen alpha 1. When Col11a1 was knocked down, the expression of BMP-2-induced markers alkaline phosphatase, Runx2, osteocalcin, and collagen 1 alpha 1 were reduced at 24h post induction with BMP-2 suggesting a role for collagen XI alpha 1 during early osteoblast differentiation. In ATDC5 cells, I determined a role for PTHrP in the induction of collagen XI alpha 1 exons 6A, 7, and 8 during early chondrocyte differentiation and exon 6B during late chondrocyte differentiation. Overall the results of this project show a novel role for collagen XI alpha 1 in BMP-2-mediated osteoblast differentiation and also suggest a role for PTHrP in regulating collagen XI alpha splicing and expression during ATDC5 chondrocyte differentiation
A Qualitative Review of the Supplemental Nutrition Assistance Program (SNAP) and Recommendations for Improving Nutritional Output
The Food Stamp Program (FSP) is a federal food assistance program for income-eligible individuals and households aimed at preventing hunger and improving nutrition (SNAP, 2016). Although immense growth in the program over the years has served millions of people, a growing body of research has found that program participants consume more calories, less fresh fruits and vegetables, and purchase more sugar-sweetened beverages than their non-participant counterparts (Leung, Blumenthal, Hoffnagle, Jensen, Foerster, Nestle, & Willett, 2013; Nguyen, Shuval, Njike, & Katz, 2014; Bleich, Vine, & Wolfson, 2013).
Additionally, other studies have found that SNAP participants consume more high-fat dairy and processed meats and fewer nuts, seeds, and legumes than comparable non-participants (Bleich, Vine, & Wolfson, 2013). In the aggregate, the research suggests a correlation between program participation and long term diminished nutrition. In additional to nutritional deficiencies, concerns about increased program spending, welfare dependence, and fraud and abuse have also surfaced over the years (Schanzenbach, 2013).
In response to growing concern and criticism, Congress passed the Food, Conservation, and Energy Act (FCEA) of 2008, which among other things, changed the name of the Food Stamps Program to the Supplemental Nutrition Assistance Program (SNAP), thereby promoting diet quality (nutrition) rather than simply promoting food (Leung, Ding, Catalano, et. al., 2012). The new law acknowledged fundamental deficiencies in SNAP and brought them to the forefront of a political agenda, paving the way for more substantive future changes.
Studying SNAP’s nutritional impact and amending ineffective policies is critical because of the program’s sheer size and impact (Leung, Cluggish, Villamor, Catalano, et. al., 2014). Today, SNAP is the largest federal nutrition-assistance program in the country, with 44.6 million Americans currently enrolled (Leung, et al., 2014). This paper analyzes aspects of SNAP’s nutritional delinquencies and seeks to develop recommendations for healthy legislative reforms

Effective Strategies for Building Trust in Virtual Teams
Virtual teams often fail to achieve their objectives because virtual team leaders lack strategies for nurturing trust among dispersed team members. The purpose of this single case study was to explore strategies virtual team leaders in large corporate banks use to build trust among virtual team members. The population of this study included 6 virtual team leaders from a large corporate bank located in the northeast region of the United States. The interpersonal trust theory was the conceptual framework of this study. Data were collected via semistructured telephone interviews and review of company documents. The data analysis process included content analysis and thematic analysis for theme identification. Data analysis revealed four themes related to strategies that leaders of virtual teams can use to build trust among team members: reliable technology, effective communication, teamwork and participation, and respect for people and culture. A fifth theme emerged related to barriers to trust strategies. The implications for positive social change include the potential to improve work environments for virtual team members isolated because of the absence of a social context
