Review of the Bangladesh Female Secondary School Stipend Project Using a Social Exclusion Framework

The Female Secondary School Stipend Project in Bangladesh was established to increase the enrollment of girls in secondary schools, thereby delaying marriage and childbearing. This analysis examined the existing data using the social exclusion framework to clarify the primary exclusionary factors that have kept girls from education: harassment, poverty, and the primacy of marriage and childbirth and explored the extent to which the project has diminished such barriers. While causality is difficult to establish, data suggest that the stipend programme has contributed to the rise in enrollment of girls in secondary schools. Questions remain as to the impact of the stipend programme on delaying marriage, empowerment of girls and women, and enhancing employment opportunities. A thorough assessment of the impact is required. The case study suggests that, if the programme design had focused on the quality and content of education and the broader economic and social context, more opportunities would have been created for social and economic participation of girls

Civil Society, Health, and Social Exclusion in Bangladesh

Civil society has the potential to have a positive impact on social exclusion and health equity through active monitoring and increased accountability. This paper examines the role of civil society in Bangladesh to understand why this potential has not been realized. Looking at two models of civil society action—participation in decentralized public-sector service provision and academic think-tank data analysis—this analysis examines the barriers to positive civil society input into public policy decision-making. The role of non-governmental organizations, political, cultural and economic factors, and the influence of foreign bilateral and multilateral donors are considered. The paper concludes that, with a few exceptions, civil society in Bangladesh replicates the structural inequalities of society at large

Estimating probabilities from experimental frequencies

Estimating the probability distribution 'q' governing the behaviour of a certain variable by sampling its value a finite number of times most typically involves an error. Successive measurements allow the construction of a histogram, or frequency count 'f', of each of the possible outcomes. In this work, the probability that the true distribution be 'q', given that the frequency count 'f' was sampled, is studied. Such a probability may be written as a Gibbs distribution. A thermodynamic potential, which allows an easy evaluation of the mean Kullback-Leibler divergence between the true and measured distribution, is defined. For a large number of samples, the expectation value of any function of 'q' is expanded in powers of the inverse number of samples. As an example, the moments, the entropy and the mutual information are analyzed.Comment: 10 pages, 3 figures, to be published in Physical Review

The Group-lending Model and Social Closure: Microcredit, Exclusion, and Health in Bangladesh

According to social exclusion theory, health risks are positively associated with involuntary social, economic, political and cultural exclusion from society. In this paper, a social exclusion framework has been used, and available literature on microcredit in Bangladesh has been reviewed to explore the available evidence on associations among microcredit, exclusion, and health outcomes. The paper addresses the question of whether participation in group-lending reduces health inequities through promoting social inclusion. The group-lending model of microcredit is a development intervention in which small-scale credit for income-generation activities is provided to groups of individuals who do not have material collateral. The paper outlines four pathways through which microcredit can affect health status: financing care in the event of health emergencies; financing health inputs such as improved nutrition; as a platform for health education; and by increasing social capital through group meetings and mutual support. For many participants, the group-lending model of microcredit can mitigate exclusionary processes and lead to improvements in health for some; for others, it can worsen exclusionary processes which contribute to health disadvantage

The entropy of ``strange'' billiards inside n-simplexes

In the present work we investigate a new type of billiards defined inside of $n$--simplex regions. We determine an invariant ergodic (SRB) measure of the dynamics for any dimension. In using symbolic dynamics, the (KS or metric) entropy is computed and we find that the system is chaotic for all cases $n>2$.Comment: 8 pages, uuencoded compressed postscript fil

A meta-analysis of gene expression signatures of blood pressure and hypertension

Genome-wide association studies (GWAS) have uncovered numerous genetic variants (SNPs) that are associated with blood pressure (BP). Genetic variants may lead to BP changes by acting on intermediate molecular phenotypes such as coded protein sequence or gene expression, which in turn affect BP variability. Therefore, characterizing genes whose expression is associated with BP may reveal cellular processes involved in BP regulation and uncover how transcripts mediate genetic and environmental effects on BP variability. A meta-analysis of results from six studies of global gene expression profiles of BP and hypertension in whole blood was performed in 7017 individuals who were not receiving antihypertensive drug treatment. We identified 34 genes that were differentially expressed in relation to BP (Bonferroni-corrected p<0.05). Among these genes, FOS and PTGS2 have been previously reported to be involved in BP-related processes; the others are novel. The top BP signature genes in aggregate explain 5%-9% of inter-individual variance in BP. Of note, rs3184504 in SH2B3, which was also reported in GWAS to be associated with BP, was found to be a trans regulator of the expression of 6 of the transcripts we found to be associated with BP (FOS, MYADM, PP1R15A, TAGAP, S100A10, and FGBP2). Gene set enrichment analysis suggested that the BP-related global gene expression changes include genes involved in inflammatory response and apoptosis pathways. Our study provides new insights into molecular mechanisms underlying BP regulation, and suggests novel transcriptomic markers for the treatment and prevention of hypertension.Tianxiao Huan, Tõnu Esko, Marjolein J.

Synthesis and structure of new oligomethylene-bridged double ladders. How far can the layers be separated?

The synthesis of the &alpha;,&omega;-bis[dichloro(trimethylsilylmethyl)stannyl]alkanes, (Me3SiCH2)C12Sn(CH2)nSnCl2(CH2SiMe3) (13, n=5; 14, n=6; 15, n=7; 16, n=8; 17, n=10; 18, n=12) and the corresponding oligomethylene-bridged diorganotin oxides [(Me3SiCH2)(O)Sn(CH2)nSn(O)(CH2SiMe3)]m (19, n=5; 20, n=6; 21, n=7; 22, n=8; 23, n=10; 24; n=12) is reported. The reaction of the diorganodichlorostannanes 13&ndash;18 with the corresponding diorganotin oxides 19&ndash;24 provided the spacer-bridged tetraorganodistannoxanes {[(Me3SiCH2)ClSn(CH2)nSnCl(CH2SiMe3)]O}4 (25, n=5; 26, n=6; 27, n=7; 28, n=8; 29, n=10; 30, n=12). Compounds 13&ndash;30 have been identified by elemental analyses and multinuclear NMR spectroscopy. Compounds 25, 27, 29 and 30 have also been characterised by single crystal X-ray diffraction analysis and electrospray mass spectrometry. For the latter the essential double ladder motif is maintained for all n in the solid state, but subtle changes in alignment of the ladder planes occur. Separation between the two layers of the double ladder ranges from approx. 8.7&nbsp; &Aring; (for 25, n=5) to approx. 15 &Aring; (for 30, n=12). In solution there is some dissociation of the double ladders into the corresponding dimers. The degree of dissociation is favoured by increasing oligomethylene chain length n.<br /

Patterned growth of single-walled carbon nanotube arrays from a vapor-deposited Fe catalyst

Single-walled carbon nanotubes have been grown on a variety of substrates by chemical vapor deposition using low-coverage vacuum-deposited iron as a catalyst. Ordered arrays of suspended nanotubes ranging from submicron to several micron lengths have been obtained on Si, SiO2,SiO2, Al2O3,Al2O3, and Si3N4Si3N4 substrates that were patterned on hundred nanometer length scales with a focused ion beam machine. Electric fields applied during nanotubegrowth allow the control of growth direction. Nanotube circuits have been constructed directly on contacting metal electrodes of Pt/Cr patterned with catalysts. Patterning with solid iron catalyst is compatible with modern semiconductor fabrication strategies and may contribute to the integration of nanotubes in complex device architectures.Physic
