Home bias persistence in foreign direct investments

The purpose of this paper is to analyse the issues related to home bias and foreign direct investments (FDIs). We study the role of physical, cultural, and institutional distances from home on FDI decisions taken by corporations to assess whether the globalization of the past two decades has reduced their influence. Using the ‘home bias’ framework from the finance literature and the gravity model from the economics literature, we utilize a large sample of both developed and emerging markets, using FDI flows of 6263 unique bilateral country pairs over a 30-year period. We find strong empirical evidence of persistent home bias in FDI outflows, and we show that not only physical distance but also cultural and institutional similarities between host and source countries remain a decisive factor in foreign corporate investment decisions. We also show that such home bias is persistent over time and is observed around the world.

RT-Bst: an integrated approach for reverse transcription and enrichment of cDNA from viral RNA

The synthesis of cDNA from RNA is challenging due to the inefficiency of reverse transcription (RT). In order to address this, a method was developed known as RT-Bst for sequential RT of RNA and Bst DNA polymerase amplification for enrichment of cDNA in a single tube reaction. Using genomic RNA from bacteriophage MS2, the yield of cDNA produced by RT alone and RT-Bst were compared by analysis of PCR-amplified products. Using random primers a superior performance was observed when amplifying MS2 RNA following RT-Bst compared to RT alone, indicating that greater quantities of cDNA were present after RT-Bst. RT-Bst was also compared with RT alone for their relative ability to produce sufficient cDNA to amplify 8 target regions spanning the respiratory syncytial virus (RSV) genome. Six out of 8 targets were amplified consistently by PCR subsequent to RT-Bst amplification whereas only 3 out of 8 targets could be amplified after RT alone. RSV sequences were selectively amplified using RSV specific primers from a mixed template containing an excess of MS2 RNA in a RT-Bst reaction without amplifying MS2 sequences. This suggests that RT-Bst can be used to amplify RNA sequences non-specifically using random primers and specifically using sequence specific primers and enhances the yield of cDNA when compared to RT alone.

Reducing job-irrelevant bias in performance and appraisals: compliance and beyond

Job-irrelevant discrimination seems as ubiquitous as the performance appraisals in which it is commonly detected. This paper explores both compliance-based and more proactive approaches that deal with the various possible sources of discrimination in performance appraisal ratings. The suggestions lead to a code of practice for performance management in firms across cultures and national boundaries.
