Engines of Liberation

Electricity was born at the dawn of the last century. Households are inundated with a flood of consumer durables. What was the impact of this consumer goods revolution. It is argued here that the consumer goods revolution was conducive to liberating women from the home. To analyze this hypothesis, a Beckerian model of household production is developed. Households must decide whether or not to adopt the new technologies and whether a married woman should work. Can such a model help to explain the rise in married female labor-force participation that occurred in the last century? Yes.The second industrial revolution, technology adoption, household production theory, female labor force participation.

Acts of Belonging: Perceptions of Citizenship Among Queer Turkish Women in Germany

This thesis examines how people who have multiple identifications develop a sense of belonging. It focuses on those with politicized, romanticized, and stigmatized identifications which are assumed to be in conflict with one another. My particular case is that of queer women of Turkish descent in Germany with Berlin as my main study site. These people embody what is considered to be an oxymoron: being queer yet also Turkish, being a lesbian yet having a Muslim background, being of immigrant origin yet also German. In short, they are between all worlds and thus, seemingly, do not belong anywhere. Their ambiguous position allows my thesis to offer a critique of mainstream ideas about cohesion and social capital, noting that in this case, cohesion is not needed for my informants to develop a sense of belonging. From here, it develops the concept of what I call acts of belonging. This concept directs our attention away from the question of where belonging happens to the question of how: how do migrants belong to contexts, communities, societies to which the mainstream does not consider them to belong?What relieves them from the burdens their conflicting identifications might otherwise cause? Acts of belonging are the tools, the means, through which they relieve this anxiety, even momentarily, and satisfy their individual need for belonging. Acts of belonging also points at the ways in which legal acceptance, in the form of citizenship or naturalization, differs from lived experiences of belonging. Finally, these acts reveal the ways in which people engage with diversity in various ways which are not always obvious to the reveal the ways in which people By looking simultaneously at psycho-social and emotional factors on the one hand and sexuality on the other, my research bridges various gaps in the literatures of queer studies, migration and citizenship, and social psychology. My work presents an alternative way to look through the lens of belonging at the relationship between cohesion and conflict

An entropy based heuristic model for predicting functional sub-type divisions of protein families

Multiple sequence alignments of protein families are often used for locating residues that are widely apart in the sequence, which are considered as influential for determining functional specificity of proteins towards various substrates, ligands, DNA and other proteins. In this paper, we propose an entropy-score based heuristic algorithm model for predicting functional sub-family divisions of protein families, given the multiple sequence alignment of the protein family as input without any functional sub-type or key site information given for any protein sequence. Two of the experimented test-cases are reported in this paper. First test-case is Nucleotidyl Cyclase protein family consisting of guanalyate and adenylate cyclases. And the second test-case is a dataset of proteins taken from six superfamilies in Structure-Function Linkage Database (SFLD). Results from these test-cases are reported in terms of confirmed sub-type divisions with phylogeny relations from former studies in the literature

Development and testing of indoor soundscape questionnaire for evaluating contextual experience in public spaces

An Indoor Soundscape Questionnaire aiming at the evaluation of indoor public sound environments was designed, statistically tested and presented. It was established through initial pilot studies and three main factors under contextual experience variable are established as (1) psychological factors, (2) space usage factors and (3) demographical factors. In addition to the questions on demographical and space usage factors, detailed questions on psychological factors are designed and statistically tested for expectation, perception and reaction categories of the psychological factor. The questionnaire was applied as part of a case study in enclosed library foyer environments to a group of 270 participants through non-experimental survey data sampling. The reliability and validity scores of the Indoor Soundscape Questionnaire were statistically tested and confirmed. Furthermore, statistical tests were used to derive relationships between contextual experience variables of psychological, space usage and demographical factors. Chi-square test of goodness-of-fit results showed statistical significances of demographical and space usage factors with the psychological factors

Traversing the k-mer Landscape of NGS Read Datasets for Quality Score Sparsification

It is becoming increasingly impractical to indefinitely store raw sequencing data for later processing in an uncompressed state. In this paper, we describe a scalable compressive framework, Read-Quality-Sparsifier (RQS), which substantially outperforms the compression ratio and speed of other de novo quality score compression methods while maintaining SNP-calling accuracy. Surprisingly, RQS also improves the SNP-calling accuracy on a gold-standard, real-life sequencing dataset (NA12878) using a k-mer density profile constructed from 77 other individuals from the 1000 Genomes Project. This improvement in downstream accuracy emerges from the observation that quality score values within NGS datasets are inherently encoded in the k-mer landscape of the genomic sequences. To our knowledge, RQS is the first scalable sequence-based quality compression method that can efficiently compress quality scores of terabyte-sized and larger sequencing datasets.
