Employee Engagement and Relationship Practices in Start-up organizations

In order to stay competitive in today’s fast changing world, presence of the best talent depicts the success or failure of the organisation. Who you hire is not just important, but how the employee is managed and retained is considered important by Kennedy and Diam, 2010. Initially considered as a cheap labour force provider, India witnessed reduction in product development and innovation. By the introduction of initiatives by the new Government, raise in funding of about $3.5 to$5 billion in 2015 marked the beginning of job providing market in India. Hiring and retaining skilled manpower is considered as a huge challenge for the start-up to be successful and uncertain organisation climate change is the reason. (Banerjee 2017, Lee Hom and Liz 2017). The inherent uncertainty of organizational growth has resulted in a level of systematic flexibility regarding internal operations requiring high endand allowing for contingent leadership to take place. While flexibility allows optimal resource utilization, on the other hand it can also result in employees feeling aloof, stressed and de-motivated (Banerjee 2017).If these issues remain unanswered, the employee becomes disengaged and leaves for better opportunity. This study focuses on HRM practices (i.e. employee engagement and retention) in start-ups, effectiveness of practices (employee satisfaction) and challenges the start-ups will face in competitive setup. The study makes use of qualitative data and is collected through narrative enquiry. The data isanalysed using ISM technique; excel with focus on HRM practices start-ups and its impact on retentionship and engagement outcomes

Diversity and dominance of flora around wetlands in Lakkavalli Range of Bhadra Wildlife Sanctuary, Karnataka

The present communication is based upon a research work and the building a database for plants in the wetlands of Lakkavalli range of Bhadra Wildlife sanctuary. From these wetlands, about 133 species of plants have been identified of which herbs (27), shrubs (22) climbers (19) and trees (65).The objective of the work was to help wetland managers and ecologists by providing an account of the floral characteristics around wetland community

A Study on Physico-Chemical Characteristics of Water in Wetlands of Hebbe Range in Bhadra Wildlife Sanctuary, Mid Westernghat Region, India

A systematic study has been carried out to evaluate physico chemical characteristics of the selected wetlands of the Bhadra Wildlife sanctuary from May 2009 to April 2010. Three major wetlands which come across the temperate zone of the sanctuary have been selected for the study. Seventeen physico-chemical water quality parameters have been analyzed for pre, post and monsoon seasons. Idan ban kere has a less Catchment area compared to the other two. The pH of the water was found to be more alkaline in Idan ban kere compared to the others. The values of DO and BOD fluctuate according to the seasons and sectors, COD was very less due to absence of chemical pollution. The value of all the parameters are found to be more during pre monsoon season when compared to monsoon and post monsoon in Idan ban kere with comparison to Heggarna kere and Gonimara hadla kere, due to their differences in the catchment area and occurrence of high amount of rainfall during monsoon. Other parameters such as calcium, magnesium, sulphate and phosphate were under permissible limits and widely fluctuated according to seasons and sectors

Encounter rate of large mammals in Thanigebyle range of Bhadra wildlife sanctuary, Karnataka

Estimation of large mammals by using line transact method in the Thanigebyle range of Bhadra Wildlife Sanctuary during May 2009 to April 2010 in Thanigebyle range for four species of large herbivorous mammals viz., Chital (Axis axis), Sambar (Cervus unicolor), Barking deer (Muntiacus muntjak) and Gaur (Bosgaurus). The sanctuary was divided into several zones based on location and habitat types. Four permanent walking transect of 1 km were cut in different habitats of water holes for direct count and walk once in each month and four permanent vehicle transects of 18 kms were made.  A total of 22 kms per month transect was evaluated including both walking transect and permanent vehicle transect of 4 kms and 18 kms respectively. This evaluation indicates that maximum number of individuals was observed in the walking transect when compared to vehicle transect for all the four species. During our study 21 Sambar, 161 Chital, 8 Barking deer and 21 Gaur was encountered. Chital was observed more in the study area. It also reveals that during pre monsoon and post monsoon seasons the number of individuals was observed to be higher. &nbsp

Synthesis of single crystalline (NH4)(2)V6O16 center dot 1.5H(2)O nest-like structures

Novel nest-like (NH4)(2)V6O16 center dot 1.5H(2)O structures made of nanobelts have been synthesized by a facile hydrothermal approach. The powder X-ray diffraction pattern of the sample reveals the monoclinic crystalline phase of (NH4)(2)V6O16 center dot 1.5H(2)O. The scanning electron microscopy images of the sample obtained at 130 degrees C for 3 days exhibit nest-like morphology. The transmission electron microscopy result reveals that the nanobelts have a smooth surface. The selected area electron diffraction pattern of the nanobelts indicates single crystalline nature. The two major weight losses occur in thermogravimetric analysis which correspond to the removal of water and ammonia molecules. Further, calcination of the (NH4)(2)V6O16 center dot 1.5H(2)O product results in the formation of orthorhombic phase of shcherbianite V2O5. (C) 2014 Elsevier B.V. All rights reserved
