Upstream and Downstream Impacts of College Merit-Based Financial Aid for Low-Income Students: Ser Pilo Paga in Colombia

How does financial aid affect postsecondary enrollment, college choice, and student composition? We present new evidence based on a large-scale program available to high-achieving, low-income students for attending high-quality colleges in Colombia. RD estimates show financial aid eligibility raised immediate enrollment by 56.5 to 86.5 percent, depending on the complier population. This rise, driven by matriculation at private, high-quality colleges, closed the SES enrollment gap among high achievers. Moreover, a DID approach suggests enrollment of aid-ineligible students also improved because college supply expanded in response to heightened demand. With ability stratification largely replacing SES stratification, diversity increased 46 percent at private, high-quality colleges.
Performance and Safety of LPG Refrigerants

Ozone depletion and global warming require replacement of chlorofluorocarbon refrigerants like R12. The hydrofluorocarbon R134a is nonflammable, difficult to synthesize, has zero ozone depletion and high global warming. LPG refrigerants are highly flammable, occur naturally, have zero ozone depletion and negligible global warming. In Germany, most new refrigerators use R600a and many heat pumps and air conditioners now use R290 with measured energy consumption 10 to 20% lower than R12, R134a or R22. LPG mixtures have successfully replaced R12 and R134a in over 100,000 US car air-conditioners. Abboud (1994) measured the air-conditioner performance of five popular Australian cars with R12 and then LPG mixtures in our laboratory. He recommended 60% by mass commercial propane from Bass Strait and 40% commercial butane. This gave typically 10% more cooling than R12 with satisfactory superheat and typically 8% higher condenser pressure. Refrigerant property parameters show that R600a has half the leakage, pressure loss and condenser pressure and double the heat transfer properties of R12 and R134a. This explains the energy consumption savings of R600a refrigerators. Redesign of heat pumps and car airconditioners for R600a could yield greater benefits. The insurance risk increment from LPG flammability for domestic refrigerators is zero. The increment for car air-conditioners is negative because of the high cost of R12 and R134a repairs. For large systems, ventilation of plantrooms and other LPG safety precautions can make insurance risk increment zero or negative if required. ∗Proceedings of the ‘Fuel for Change’ Conference of the Australian Liquefied Petroleum Gas Association Ltd, ISBN 0 646 24884 7, Surfers’ Paradise Queensland, pp. 149–168, 28th February to 2nd March, 1995. 2 1 REFRIGERANT HISTORY
Title : Tissue Culture and Plant Regeneration from Immature Embryo Explants of Twenty-two Genotypes of Barley , Hordeum vulgare

approved: Redacted for Privacy Immature embryo explants taken eight days after anthesis were used to establish callus cultures of spring barley. Two types of calli were observed. A soft watery callus which produced a limited number of shoots and a harder yellowish callus that gave rise to numerous green primordia and shoots. Gamborg's B5 basal medium supplemented with either 2,4-D 2,4-dichlorophenoxyacetic acid) or C13 POP (2,4,5trichlorophenoxypropionic acid) was found to support the growth and formation of callus capable of shoot and root development. Among the hormone concentrations tested, 2,4-D at 1.0 mg L -1 and Cl 3 POP at 5.0 mg L -1 gave rise to numerous callus cultures capable of plantlet regeneration. Twenty genetically diverse genotypes were screened to determine if the methods developed were suitable for tissue culture propagation of spring barley cultivars. Regeneration of plantlets was achieved for 19 of the 20 genotypes approximately 4 months after culture initiation. Differences were detected in the ability of these genotypes to develop into vigorously growing callus cultures capable of shoot and root initiation. Specific cultivars and advanced breeding program lines have been identified for their ability to produce many shoots and several plantlets from a single embryo explant. Evidence for heterosis in tissue culture was found for callus production, root and shoot development, and regeneration of plantlets in four spring barley crosses. A heterotic effect was detected in all F 1 tissue culture populations for plantlet regeneration and gain in fresh weight 9 weeks after culture initiation. The results clearly demonstrate that heterosis was present in F1 tissue culture populations from spring barley crosses. The increase in numbers of plants regenerated suggests that F1 materials are well suited for tissue culture studies directed towards the genetic improvement of
DIFFERENTIAL DIAGNOSIS OF HYPERTENSIVE DISORDERS IN PREGNANCY BASED ON URINE PEPTIDOME PROFILE ANALYSIS

As preeclampsia (PE) accounts for high rate of maternal and perinatal morbidity and mortality and has shortand long-term consequences, its prediction and early (preclinical) diagnosis is of utmost importance [1–5]. Thus, differential diagnosis of hypertensive disorders in pregnancy is of current interest as these pathologies affect not only outcomes for the mother and fetus but their future quality of life as well. According to the international recommendations proteinuria is no longer a criterion of PE as one cannot exclude preexisting urinary tract pathology [2-6]. Meanwhile there are data that proteinuria can precede PE [7]. Non-significant proteinuria often accompanies hypertension and proteome/peptidome analysis is a promising tool for accurate PE detection.

BDNF as a Model System for examining Gene by Environment Interactions across Development

There has been a dramatic rise in gene x environment studies of human behavior over the past decade that has moved the field beyond simple nature versus nurture debates. These studies offer promise in accounting for more variability in behavioral and biological phenotypes than studies that focus on genetic or experiential factors alone. They also provide clues into mechanisms of modifying genetic risk or resilience in neurodevelopmental disorders. Yet, it is rare that these studies consider how these interactions change over the course of development. In this paper, we describe research that focuses on the impact of a polymorphism in a brain-derived neurotrophic factor (BDNF) gene, known to be involved in learning and development. Specifically we present findings that assess the effects of genotypic and environmental loadings on neuroanatomic and behavioral phenotypes across development. The findings illustrate the use of a genetic mouse model that mimics the human polymorphism, to constrain the interpretation of gene-environment interactions across development in humans.
INDOOR PARTICLE SIZE DISTRIBUTION IN OFFICE

In this research, the particle size distribution (0.3μm-0.5μm, 0.5μm-0.7μm, 0.7μm-1.0μm, 1.0-2.5μm, 2.5μm5.0μm, >5.0μm) with the variety of activities (printing, photocopying and use of air freshener spray) in administrative office were measured. The direct reading instruments were used to measure number particulate matter and environmental parameters (temperature, relative humidity and air velocity). Air Exchange Rate (AER) was determined by using a tracer gas technique. The predominance size of particulate is 0. 3μm to 0. 5μm with 8901 number/cm3 and 4699 number/cm3. The use of air freshener illustrates the highest emission rate, which is 3.73x1010s-1. Significant elevation of indoor particle concentration was noted during these three activities. The photocopy activity can be a major source of indoor particle concentration due to high number of particles emitted within short periods and the particles remain fluctuated in the indoor air with slow decay rate.
Recognition of geochemical footprints of mineral systems in the regolith at regional to continental scales

ARTICLE HISTORY Received 31 May 2016 Accepted 1 November 2016 ABSTRACT Understanding the character of Australia’s extensive regolith cover is crucial to the continuing success of mineral exploration. We hypothesise that the regolith contains geochemical fingerprints of processes related to the development and preservation of mineral systems at a range of scales. We test this hypothesis by analysing the composition of surface sediments within greenfield regionalscale (southern Thomson Orogen) and continental-scale (Australia) study areas. In the southern Thomson Orogen area, the first principal component (PC1) derived in our study [Ca, Sr, Cu, Mg, Au and Mo at one end; rare earth elements (REEs) and Th at the other] is very similar to the empirical vector used by a local company (enrichment in Sr, Ca and Au concomitant with depletion in REEs) to successfully site exploration drill holes for Cu–Au mineralisation. Mapping of the spatial distribution of PC1 in the region reveals several areas of elevated values and possible mineralisation potential. One of the strongest targets in the PC1 map is located between Brewarrina and Bourke in northern New South Wales. Here, exploration drilling has intersected porphyry Cu–Au mineralisation with up to 1 wt% Cu, 0.1 g/t Au, and 717 ppm Zn. The analysis of a comparable geochemical dataset at the continental scale yields a compositionally similar PC1 (Ca, Sr, Mg, Cu, Au and Mo at one end; REEs and Th at the other) to that of the regional study. Mapping PC1 at the continental scale shows patterns that (1) are spatially compatible with the regional study and (2) reveal several geological regions of elevated values, possibly suggesting an enhanced potential for porphyry Cu–Au mineralisation. These include well-endowed mineral provinces such as the Curnamona and Capricorn regions, but also some greenfield regions such as the Albany-Fraser/western Eucla, western Murray and Eromanga geological regions. We conclude that the geochemical composition of Australia’s regolith may hold critical information pertaining to mineralisation within/beneath it.
Effects of implementation of the Next Generation Science Standards on the math performance of 5th grade students with ADHD

Robert Zimmer EFFECTS OF IMPLEMENTATION OF THE NEXT GENERATION SCIENCE STANDARDS ON THE MATH PERFORMANCE OF 5 GRADE STUDENTS WITH ADHD 2016-2017 S. Jay Kuder, Ed.D. Master of Arts in Learning Disabilities The purpose of this study was to implement two components of the Next Generation Science Standards, gathering and reasoning, into the 5 grade math curriculum for students diagnosed with ADHD. Each student completed a 21 Century pre-assessment created by the My Math Text book (McGraw Hill, 2011) and modified by the instructor. This assessment contained 10 questions that were a culmination of the concepts that were covered in the upcoming chapter. A total of 8 students participated in the study. Of these, 4 were taught with the components of gathering and reasoning, while the rest of the 4 were involved in traditional instruction without these components. A pre-and post control group design was used in the study. The results indicated that the students learning with the components of gathering and reasoning gained slightly higher scores on the post-assessment compared to those without the components of gathering and reasoning. It seems that the components of gathering and reasoning did not have a major impact on student math scores, however using the components, students were more engaged and enjoyed in learning new concepts. Further research is recommended to determine if the components of gathering and reasoning would have a long-term effect on students with ADHD and their math performance. v
Predicting Material Accounting Misstatements

We examine 2,190 SEC Accounting and Auditing Enforcement Releases (AAERs) issued between 1982 and 2005. We obtain a comprehensive sample of firms that are alleged to have misstated their financial statements. We examine the characteristics of misstating firms along five dimensions: accrual quality, financial performance, non-financial measures, off-balance sheet activities, and market-based measures. We compare misstating firms to themselves during non-misstatement years and misstating firms to the broader population of all publicly listed firms. We find that managers appear to be hiding diminishing performance during misstatement years. We find that accruals are high and that misstating firms have a greater proportion of assets with valuations that are more subject to managerial discretion. In addition, the extent of leasing is increasing and there are abnormal reductions in the number of employees. Misstating firms are raising more financing, have higher price-to-fundamental ratios, and have strong prior stock price performance. We develop a model to predict accounting misstatements. The output of this model is a scaled logistic probability that we term the F-Score, where values greater than one suggest a greater likelihood of a misstatement.

Effect of Dietary Lipid Sources on Body Fatty Acid Composition of Chinese Longsnout Catfish Leiocassis longirostris Günther

This study investigated the effects of dietary lipid sources on growth and fatty acid composition of juvenile Chinese longsnout catfish. Triplicate groups of fish (initial average weight, 3.8 g) were fed four diets containing either fish oil (FO), soybean oil (SO), linseed oil (LO) and lauric acid (LA) for 10 weeks. There were no differences among the groups in body weight, feed intake, feed efficiency, protein efficiency ratio, and body proximate composition of fish fed the diets containing different lipid sources (P > 0.05) during the study. However, fatty acids compositions of the whole body were influenced by dietary lipid source. Fish fed the SO diet had high concentration of linoleic acid, whereas those of fish fed the LO diet were rich in linolenic acid and arachidonic acid. Fish fed the FO diet had significantly (P < 0.05) higher levels of monounsaturated fatty acids such as 18:1n-9 and 20:1n-9 than those of fish fed the SO and LO diets. Eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-3) composition of body were not influenced by dietary lipid source. The results suggest that each of FO, SO, LO or LA can be used as a lipid source in the diets of Chinese longsnout catfish without any negative effects on growth and feed utilization and these data demonstrate the potential impact which dietary fat composition can change the body fatty acid profile.
Enteropathogenic Escherichia coli O 157 Strains from Brazil

We describe two serogroup O157 Escherichia coli strains from Brazilian infants with diarrhea. A variety of assays indicate that these strains belong to the enteropathogenic, not the enterohemorrhagic, pathotype. These strains possess a novel bfpA allele encoding the type IV pilin characteristic of typical enteropathogenic E. coli strains. Our results emphasize the pitfalls of classifying pathogenic E. coli by serogroup.
Hold ’ em Caching : Proactive Retention-Aware Caching with Multipath Routing for Wireless Edge Networks

We consider the problem of proactive retention aware caching in a heterogeneous wireless edge network consisting of mobile users connected to a server and associated to one or more edge caches. Our goal is to design a caching policy that minimizes the sum of content storage costs and server access transmissions costs over two design variables: the retention time of each cached content and the probability that a user routes content requests to its associated caches. We develop a model that captures multiple aspects such as cache storage costs and several capabilities of modern wireless technologies, such as server multicast/unicast transmissions, device multipath routing, and cache access constraints. We formulate the problem of Proactive Retention Routing Optimization (PRRO) as a non-convex, non-linear mixed-integer program. We prove that it is NP-Hard under both multicast/unicast modes, even when the caches have a large capacity, and develop a greedy algorithm that has provable performance bounds. Finally, we propose a heuristic for the capacitated cache case that has low computational complexity. Systematic evaluations including real data sets demonstrate the effectiveness of our approach, compared to the existing caching schemes.
ADDRESSING STUDENTS ’ CONCEPTIONS OF COMMON FRACTIONS

Grade 6 and 7 South African upper elementary school students’ conceptions of and operations with common fractions were investigated before and after a year of exposure to materials which had been designed to challenge common limiting constructions identified in a previous study, and to a teaching approach of which reflection and interaction are essential components. There was a significant improvement in several of the items in the written tests, in line with the aims and extent of the materials used.
CROSS CULTURAL DIFFERENCES AND THEIR IMPLICATIONS FOR MANAGING INTERNATIONAL PROJECTS

Effective use of cross cultural teams can provide a source of experience and innovative thinking to enhance the competitive position of organizations. However, cultural differences can interfere with the successful completion of projects in today’s multicultural global business community. To achieve project goals and avoid cultural misunderstandings, project managers should be culturally sensitive and promote creativity and motivation through flexible leadership. This paper describes the most well known and accepted cross cultural management theories. These theories consider relations between people, motivational orientation, orientation toward risk, definition of self and others, attitudes to time, and attitudes to the environment. We discuss motivation and training of multicultural project teams and relevant implications for project management. We provide examples of success and failure in international, multicultural projects. The paper concludes that global project management can succeed through culturallyaware leadership, cross cultural communication, and mutual respect. Without them, it is destined to fail.
Acculturation , Coping Styles , and Health Risk Behaviors Among HIV Positive Latinas

This study examined the relationships among acculturation, coping styles, substance use, sexual risk behavior, and medication non-adherence among 219 Latinas living with HIV/AIDS in Los Angeles, CA. Coping styles were hypothesized to mediate the link between acculturation and health risk behaviors for HIV positive Latinas. Structural equation modeling revealed that greater acculturation was related to less positive coping and more negative coping. In turn, negative coping was associated with more health risk behaviors and more non-adherence. Positive coping was associated with less substance use as reflected in use of cigarettes and alcohol and less non-adherence. Coping styles mediated the relationship between acculturation and health risk behaviors. Findings echo previous works examining the Hispanic Health Paradox wherein more acculturated Latinos exhibit increased risk behavior and maladaptive coping styles. HIV/AIDS interventions need to be mindful of cultural differences within Hispanic populations and be tailored to address these differences.
Influence of School-Based Income Generating Projects on Students ’ Retention Rate in Secondary Education in Kenya

The purpose of the study was to find out influence of school based income generating projects on retention rate in secondary education in Kisii County. The objectives of the study were to: find out various income generating projects; find out how income generating projects were utilized to address students’ retention rate and establish the challenges facing sustenance of Income Generating Projects (IGPs) on retention of students in secondary schools. The target populations of the study were: 60 principals, 95 class teachers, 4267 form four students, 60 bursars and 1 Sub county quality assurance and standards officer (SQASO). Simple random sampling technique was used to obtain 24 principals, 24 bursars, 38 class teachers and 214 form four students. Purposive sampling in addition was used to select the SQASO. The study employed a descriptive survey design. Instruments for data collection involved semistructured questionnaire and interview schedule. Conceptual framework was employed. Validity of instruments was enhanced under close consultations and guidance of the supervisors. Test-retest method was used to establish reliability of the instruments and a correlation coefficient of 0.87 was obtained. Quantitative data was analyzed using descriptive statistics that included percentages and frequency counts while qualitative data was analyzed thematically. Findings of the study were: secondary schools had various IGPs with the majority of the schools engaging in agricultural based projects; IGPs were used to supplement students’ tea break, lunch, supper and buying uniform to bright but needy students and this has led to average retention of students. The main Challenge facing the Income Generating projects was lack of proper records. The study concluded that majority of the schools were engaged in IGPs as a way of supplementing the school budget with improved accessibility. The study recommends that there should be proper and upto -date records on IGPs and which should be audited twice a year as a way of accountability and that a study should be carried out with a focus on the influence of school based income generating projects on students’ retention rates in primary schools.
