"The Consolidated Assistance Program, Reforming Welfare by Synchronizing Public Assistance Benefits"
No full textLevin-Waldman examines the structure of existing welfare programs and concludes that the current array of benefits could be synchronized and consolidated to create a new system that would provide economic incentives to work. He suggests combining elements of the earned income tax credit (EITC) and current welfare programs into one program, a consolidated assistance program (CAP). Levin-Waldman argues that a program composed of an assistance component (with one set of benefits for working parents and a different set for nonworking parents) and a child support component could be designed to assure minimal subsistence to those unable to work while providing incentives for those on welfare to work without, in effect, penalizing them for getting off welfare. Such a program would reform welfare more expeditiously than a plan that would simply expand the EITC or put a time limit on welfare benefits. Moreover, such a plan would not necessarily add to the national budget deficit.

Urban-rural differences in adolescent eating behaviour : a multilevel cross-sectional study of 15-year-olds in Scotland
No full textThis work was supported by NHS Health Scotland and the Ludwig Boltzmann Institute. However, NHS Health Scotland and the Ludwig Boltzmann Institute had no role in the design, analysis or writing of this article.Objective: Improving the diet of the Scottish population has been a government focus in recent years. Population health is known to vary between geographies; therefore alongside trends and socio-economic inequalities in eating behaviour, geographic differences should also be monitored. Design: Eating behaviour data from the 2010 Scotland Health Behaviour in School-aged Children survey were modelled using multilevel linear and logistic modelling. Setting: Data were collected in schools across urban and rural Scotland. Subjects: Schoolchildren aged 15 years. Results: Adolescents living in remote rural Scotland had the highest consumption frequency of vegetables (on average consumed on 6·68 d/week) and the lowest consumption frequency of sweets and crisps (on 4·27 and 3·02 d/week, respectively). However, it was not in the major four cities of Scotland (Glasgow, Edinburgh, Dundee and Aberdeen) but in the geography described by the classification ‘other urban’ areas (large towns of between 10 000 and 125 000 residents) that adolescents had the poorest diet. Deprivation and rurality were independently associated with food consumption for all but fruit consumption. Sharing a family meal, dieting behaviour, food poverty and breakfast consumption did not differ by rurality. Variance at the school level was significant for fruit and vegetable consumption frequencies and for irregular breakfast consumption, regardless of rurality. Conclusions: Young people from rural areas have a healthier diet than those living in urban areas. The eating behaviours examined did not explain these differences. Future research should investigate why urban–rural differences exist for consumption frequencies of ‘healthy’ and ‘unhealthy’ foods.Peer reviewe
Raindrop size distribution and radar reflectivity-rain rate relationships for radar hydrology
No full textThe conversion of the radar reflectivity factor Z (mm6m-3) to rain rate R (mm h-1) is a crucial step in the hydrological application of weather radar measurements. It has been common practice for over 50 years now to take for this conversion a simple power law relationship between Z and R. It is the purpose of this paper to explain that the fundamental reason for the existence of such power law relationships is the fact that Z and R are related to each other via the raindrop size distribution. To this end, the concept of the raindrop size distribution is first explained. Then, it is demonstrated that there exist two fundamentally different forms of the raindrop size distribution, one corresponding to raindrops present in a volume of air and another corresponding to those arriving at a surface. It is explained how Z and R are defined in terms of both these forms. Using the classical exponential raindrop size distribution as an example, it is demonstrated (1) that the definitions of Z and R naturally lead to power law Z-R relationships, and (2) how the coefficients of such relationships are related to the parameters of the raindrop size distribution. Numerous empirical Z-R relationships are analysed to demonstrate that there exist systematic differences in the coefficients of these relationships and the corresponding parameters of the (exponential) raindrop size distribution between different types of rainfall. Finally, six consistent Z-R relationships are derived, based upon different assumptions regarding the rain rate dependence of the parameters of the (exponential) raindrop size distribution. An appendix shows that these relationships are in fact special cases of a general Z-R relationship that follows from a recently proposed scaling framework for describing raindrop size distributions and their properties

No full textMotivation: The analysis of gene expression data in its chromosomal context has been a recent development in cancer research. However, currently available methods fail to account for variation in the distance between genes, gene density, and genomic features (e.g. GC content) in identifying increased or decreased chromosomal regions of gene expression. Results: We have developed a model-based scan statistic that accounts for these aspects of the complex landscape of the human genome in the identification of extreme chromosomal regions of gene expression. This method may be applied to gene expression data regardless of the microarray platform used to generate it. To demonstrate the accuracy and utility of this method, we applied it to a breast cancer gene expression dataset and tested its ability to predict regions containing medium to high level DNA amplification (DNA ratio values> 2). A classifier was developed from the scan statistic results that had a ten-fold cross-validated classification rate of 93 % and a positive predictive value of 88%. This result strongly suggests that the model-based scan statistic and the expression characteristics of an increased chromosomal region of gene expression can be used to accurately predict chromosomal regions containing amplified genes.

Cerebrospinal Fluid Orexin A Levels and Autonomic Function in Kleine-Levin Syndrome
No full textStudy Objectives: Kleine-Levin syndrome (KLS) is a rare disorder of relapsing sleepiness. The hypothesis was that the syndrome is related to a change in the vigilance peptide orexin A. Methods: From 2002 to 2013, 57 patients with relapsing hypersomnolence were clinically assessed in a referral academic center in Beijing, China, and 44 (28 males and 16 females; mean age 18.3 +/- 8.9 y (mean +/- standard deviation, range 9-57 y) were determined to have clinical and behavioral criteria consistent with KLS. Cerebrospinal fluid orexin A levels and diurnal blood pressure were measured in relapse versus remission in a subgroup of patients. Results: Presenting symptoms included relapsing or remitting excessive sleepiness-associated parallel complaints of cognitive changes (82%), eating disorders (84%); depression (45%); irritability (36%); hypersexuality (18%); and compulsions (11%). Episodes were 8.2 +/- 3.3 days in duration. In relapse, diurnal values for blood pressure and heart rate were lower (P < 0.001). In a subgroup (n = 34), cerebrospinal fluid orexin A levels were similar to 31% lower in a relapse versus remission (215.7 +/- 81.5 versus 319.2 +/- 95.92 pg/ml, P < 0.001); in three patients a pattern of lower levels during subsequent relapses was documented. Conclusions: There are lower orexin A levels in the symptomatic phase than in remission and a fall and rise in blood pressure and heart rate, suggesting a role for orexin dysregulation in KLS pathophysiology.Ministry of Science and Technology [2015CB856405, 2014DFA31500]; NSFC [81420108002]; Ministry of Education in China [20120001110028]; VA Research ServiceSCI(E)[email protected]; [email protected]
Consciousness raising in foreign language vocabulary learning and reading
No full textThis study on consciousness raising in foreign language vocabulary learning and reading took place in a reading comprehension course for university students in Finland. The aim was to find out what kind of changes in vocabulary and reading strategies and related matters the students
underwent during the course and to investigate what support the course can give to the changes.
The data were collected during a three-week course where I acted as a teacher and a researcher, and through interviews five months after the course. The course offered the students consciousness raising possibilities in the form of teacher-led sessions, group work and questionnaires. These activities form the main source of the data.
Two mature students were selected under closer scrutiny. The transcribed data were analysed in four ways to 1) specify the perceived changes in vocabulary and reading strategies and in related matters, 2) to establish a link between the teacher-led consciousness raising and the
changes, 3) to illuminate the importance of reflection in the change and 4) to investigate the support of group work to the changes in strategies of finding out word meanings.
The findings of the study support the view that classroom learning does not take place in a vacuum. Both case study students showed changes in their perceptions about the reading process and about their ways of dealing with vocabulary. They also showed changes in their perceptions of themselves as learners. Both students, for example, articulated increasing confidence in themselves as language learners. It is likely that the teacher-led consciousness
raising in the classroom and, in particular, the group work helped the learners reflect on their background and learning and, thus, change. The findings also indicate that the students' perceptions of the benefits of consciousness raising lasted at least until five months after the course.
This study gave evidence that the two active learners subjectively perceived consciousness raising as beneficial. Future studies need to pay attention to the link between consciousness raising and the possible increase in proficiency. It is also important to study students whose
participation in the course is not as active as that of the two case study students in this study
Ideals, bifiltered modules and bivariate Hilbert polynomials
No full textAbstractLet R be a ring of polynomials in m+n variables over a field K and let I be an ideal in R. Furthermore, let (Rrs)r,s∈Z be the natural bifiltration of the ring R and let (Mrs)r,s∈Z be the corresponding natural bifiltration of the R-module M=R/I associated with the given set of generators introduced by Levin. The author shows an algorithm for constructing a characteristic set G={g1,…,gs} of I with respect to a special type of reduction introduced by Levin, that allows one to find the Hilbert polynomial in two variables of the bifiltered and bigraded R-module R/I. This algorithm can be easily extended to the case of bifiltered R-submodules of free R-modules of finite rankp over R
