Role of headquarter attention disparity on expatriate knowledge sharing between assignments

<p>In acknowledgement of ongoing challenges in knowledge sharing, continuous research efforts are required to reflect the ever-changing landscape.

This thesis seeks to add to the existing literature by exploring a potential new antecedent, headquarter attention disparity.

The research implements a hermeneutical research design using semi-structured interviews. These sought to discover expatriate conceptualisations of lateral knowledge sharing and the related perceptions of HQ attention disparities between subsidiaries. The study draws on the ability-motivation-opportunity framework within a knowledge sender-receiver context. Expatriates coming from high-HQ attention subsidiaries demonstrate their own understanding of the acquired knowledge, influenced by individual context.

Gynostemium morphology and floral biology of Thottea duchartrei Sivar., A.Babu & Balach. (Aristolochiaceae), an endemic species from Western Ghats, India

Gynostemium is a putative floral structure formed by the fusion of the male and female reproductive parts (stamens and carpels) through a process during its development called synorganization. Most of the Indian species of Thottea Rottb. have a prominent gynostemium in their floral architecture, with varying degrees of adnation and complexity. Even though the gynostemium is a significant taxonomic marker for the inter-specific systematics in Thottea, the scepticism and arguments on deciphering its morphology and functional parameters, including the existence of staminodes, makes it imperative to be examined in detail. The present study is the first attempt in this line which aims to explore the morphological characters of gynostemium and reproductive biology of Thottea duchartrei Sivar., A.Babu and Balach., an endemic species in the Western Ghats. Stereo zoom microscopy, SEM and reproductive biological studies were conducted providing special emphasis to the gynostemium. Detailed analysis revealed the structural and functional diversity of gynostemium with regard to its components. The study also helped to recognize the columnar outgrowths on the gynostemium as staminodes. In total, the present study helps to solve the confusions regarding the functional identity of the gynostemium T. duchartrei with regard to its morphology.

Bsh coordinates neuronal fate specification with synaptic connectivity

It is widely accepted that neuronal fate is initially determined by spatial and temporal cues acting in progenitors, followed by transcription factors (TFs) that act in post-mitotic neurons to specify their functional identity (e.g. ion channels, cell surface molecules, and neurotransmitters). It remains unclear, however, whether a single TF can coordinately regulate both steps. The five lamina neurons (L1-L5) in the Drosophila visual system, are an ideal model for addressing this question. Here we show that the homeodomain TF Brain-specific homeobox (Bsh) is expressed in a subset of lamina precursor cells (LPCs) where it specifies L4 and L5 fate, and suppresses homeodomain TF Zfh1 to prevent L1 and L3 fate. Subsequently, in L4 neurons, Bsh initiates a feed forward loop with another homeodomain TF Apterous (Ap) to drive recognition molecule DIP-β expression, which is required for precise L4 synaptic connectivity. We conclude that a single homeodomain TF expressed in both precursors and neurons can coordinately generate neuronal fate and synaptic connectivity, thereby linking these two developmental events. Furthermore, our results suggest that acquiring LPC expression of a single TF, Bsh, may be sufficient to drive the evolution of increased brain complexity.

What matters in making demand-based decisions: Time alone or difficulty too?

Which task is easier, doing arithmetic problems of specified form for some specified duration, or carrying a bucket of specified weight over some specified distance? If it is possible to choose between the “more cognitive” task and the “more physical” task, how are the difficulty levels of the tasks compared? We conducted two experiments in which participants chose the easier of two tasks, one that involved solving addition or multiplication problems (Experiment 1) or addition problems with different numbers of addends (Experiment 2) for varying amounts of time (in both experiments), and one that involved carrying a bucket of different weights over a fixed distance (in both experiments). We found that the probability of choosing to do the bucket task was higher when the bucket was empty than when it was weighted, and increased when the cognitive task was harder and its duration grew. We could account for the choice probabilities by mapping the independent variables onto one abstract variable, Φ. The functional identity of Φ remains to be determined. It could be interpreted as an inferred effort variable, subjective duration, or an abstract, amodal common code for difficulty.

Effects of biodiversity, stand factors and functional identity on biomass and productivity during the restoration of subtropical forests in Central China

Aims Biodiversity is found to have a significant promotion effect on ecosystem functions in manipulation experiments on grassland communities. However, its relative role compared with stand factors or functional identity is still controversial in natural forests. Here we examined their relative effects on biomass and productivity during forest restoration. Methods We investigated stand biomass and productivity for 24 plots (600 m 2) across restoration stages in the subtropical forests of Mt. Shennongjia, central China. We measured five key functional traits and calculated functional diversity (functional richness, evenness, and dispersion) and community-weighted mean (CWM) of traits. We used general linear models (GLMs), variation partitioning methods to test the relative importance of stand factors (density, stand age, maximum height, etc.), functional identity, species and functional diversity on biomass and productivity. Important Findings Our results illustrated that stand biomass and productivity increased significantly as forest restoration, and that community species richness increased significantly, while functional dispersion decreased significantly. Variation partitioning analyses showed that diversity had no significant pure effects on biomass and productivity. However, diversity can affect biomass and productivity through the joint effect with stand factors and functional identity. Overall, we found that stand factors had the strongest effect on biomass and productivity, while functional identity significantly affects productivity but not biomass, suggesting that modulating stand structure and species identity are effective ways to enhance forest carbon storage and sequestrations potential in forest management.

The intervening domain is required for DNA-binding and functional identity of plant MADS transcription factors

The MADS transcription factors (TF) are an ancient eukaryotic protein family. In plants, the family is divided into two main lineages. Here, we demonstrate that DNA binding in both lineages absolutely requires a short amino acid sequence C-terminal to the MADS domain (M domain) called the Intervening domain (I domain) that was previously defined only in type II lineage MADS. Structural elucidation of the MI domains from the floral regulator, SEPALLATA3 (SEP3), shows a conserved fold with the I domain acting to stabilise the M domain. Using the floral organ identity MADS TFs, SEP3, APETALA1 (AP1) and AGAMOUS (AG), domain swapping demonstrate that the I domain alters genome-wide DNA-binding specificity and dimerisation specificity. Introducing AG carrying the I domain of AP1 in the Arabidopsis ap1 mutant resulted in strong complementation and restoration of first and second whorl organs. Taken together, these data demonstrate that the I domain acts as an integral part of the DNA-binding domain and significantly contributes to the functional identity of the MADS TF.
