Conference paper (other academic/artistic)abstract
- Although there is rich literature on factors that affect participation and exit patterns ofindividuals in late working life, the emphasis on individual decision making rather thanemployer behaviour. However, the employer’s decision to hire or terminate the contracts playimportant role in unemployment and exit of the older workers in late working life.This paper aims to understand the link between the organizational structure and the sector ofthe companies in the companies’ employing behaviour of the older employees. Using Swedishregistry data that involves all companies in Sweden that have at least one gainful employeebetween the years 1990-2018, this study investigates how do age, gender, educationcomposition, sector and the scale of the company affect its likelihood of hiring and terminatingemployment of older employees by age, gender, and education.This paper shows that the likelihood of entry and exit of older employees differ among thecompanies in different sectors as well as with different age and education composition. Thiscontributes to the inequality among the groups that are structurally distributed in differentsectors or type of companies in late working life.

Wage Inequality and Job Insecurity Among Permanent and Contract Workers in India: Evidence from Organized Manufacturing Industries
- 2008

In: The ICFAI Journal of Applied Economics. - 0972-6861. ; 7:1, s. 80-111
-
Journal article (peer-reviewed)abstract
- Since the early 1990s, the employment structure of organized manufacturing industries in India has undergone substantial changes with steep rise in the use of contract workers in place of permanent workers. This process has led to increased wage inequality, discrimination as well as concern of job insecurity in the labor market. The paper focuses on wage inequality between permanent and contract workers, since contract workers earn substantially lower wages than their counterparts. The study uses data at the individual level from a recent labor survey of organized manufacturing industries in the India. The lower wage earned by contract workers is largely due to cost cutting, rather than differences in labor productivity. The issue of job insecurity has been modeled in the form of a binary logistic model. The factors affecting job security are divided into productivity-related attributes such as level of education and skill, and institutional attributes such as labor market rules and regulations and union membership. Contrary to the general expectation, the study finds that permanent workers are more concerned regarding job insecurity than the contract workers.

A novel statistical approach for jointly analyzing RNA-Seq data from F1 reciprocal crosses and inbred lines
- 2014

Journal article (peer-reviewed)abstract
- RNA sequencing (RNA-seq) not only measures total gene expression but may also measure allele-specific gene expression in diploid individuals. RNA-seq data collected from F1 reciprocal crosses in mice can powerfully dissect strain and parent-of-origin effects on allelic imbalance of gene expression. In this article, we develop a novel statistical approach to analyze RNA-seq data from F1 and inbred strains. Method development was motivated by a study of F1 reciprocal crosses derived from highly divergent mouse strains, to which we apply the proposed method. Our method jointly models the total number of reads and the number of allele-specific reads of each gene, which significantly boosts power for detecting strain and particularly parent-of-origin effects. The method deals with the overdispersion problem commonly observed in read counts and can flexibly adjust for the effects of covariates such as sex and read depth. The X chromosome in mouse presents particular challenges. As in other mammals, X chromosome inactivation silences one of the two X chromosomes in each female cell, although the choice of which chromosome to be silenced can be highly skewed by alleles at the X-linked X-controlling element (Xce) and stochastic effects. Our model accounts for these chromosome-wide effects on an individual level, allowing proper analysis of chromosome X expression. Furthermore, we propose a genomic control procedure to properly control type I error for RNA-seq studies. A number of these methodological improvements can also be applied to RNA-seq data from other species as well as other types of next-generation sequencing data sets. Finally, we show through simulations that increasing the number of samples is more beneficial than increasing the library size for mapping both the strain and parent-of-origin effects. Unless sample recruiting is too expensive to conduct, we recommend sequencing more samples with lower coverage.

Softwood hemicellulose-degrading enzymes from Aspergillus niger: Purification and properties of a β-mannanase
- 1998
-
In: Journal of Biotechnology. - 1873-4863. ; 63:3, s. 199-210
-
Journal article (peer-reviewed)abstract
- The enzymes needed for galactomannan hydrolysis, i.e. β-mannanase, α-galactosidase and β-mannosidase, were produced by the filamentous fungus Aspergillus niger. The β-mannanase was purified to electrophoretic homogeneity in three steps using ammonium sulfate precipitation, anion-exchange chromatography and gel filtration. The purified enzyme had an isoelectric point of 3.7 and a molecular mass of 40 kDa. Ivory nut mannan was degraded mainly to mannobiose and mannotriose when incubated with the β-mannanase. Analysis by 1H NMR spectroscopy during hydrolysis of mannopentaose showed that the enzyme acts by the retaining mechanism. The N-terminus of the purified A. niger β-mannanase was sequenced by Edman degradation, and comparison with Aspergillus aculeatus β-mannanase indicated high identity. The enzyme most probably lacks a cellulose binding domain since it was unable to adsorb on cellulose.
