Personality and Attitudes of Indian Young Female Workforce: Entrepreneurial Orientation by Education and Regions

This investigation analyzes the impact of region and educational background on entrepreneurial orientation of Indian young female trainees by using four personality descriptors i.e. need for achievement, innovation, personal control, and self-esteem around three attitude components i.e. affect, behavior, and cognition. The findings reflect the highest score of the respondents on the achievement motivation as compared to the other three personality descriptors (innovation, personal control, and self-esteem) and lowest score on the self-esteem dimension. Among attitude components, cognition has emerged as highest. Entrepreneurial orientation score of the sample as a whole is moderately high and female trainees from South India are having an edge over their counterparts from North India. Significant differences are not found between females of different educational backgrounds.entrepreneurial orientation, achievement, attitude, female, self-esteem

Nonlinear resonance absorption in laser-cluster interaction

Rare gas or metal clusters are known to absorb laser energy very efficiently. Upon cluster expansion the Mie plasma frequency may become equal to the laser frequency. This linear resonance has been well studied both experimentally and theoretically employing pump probe schemes. In this work we focus on the few-cycle regime or the early stage of the cluster dynamics where linear resonance is not met but nevertheless efficient absorption of laser energy persists. By retrieving time-dependent oscillator frequencies from particle-in-cell simulation results, we show that nonlinear resonance is the dominant mechanism behind outer ionization and energy absorption in near infrared laser-driven clusters.Comment: 4 pages, 4 figures, REVTeX, minor modifications according to referee comments, accepted for publication in Phys.

HRM Practices in Insurance Companies: A Study of Indian and Multinational Companies

Competitive advantage of a company can be generated from human resources (HR) and company performance is influenced by a set of effective HRM practices. In this study, we intended to assess the HR practices in insurance companies. Primary data based on 218 respondents from four insurance companies (two multinational-7 branches and two Indian-7 branches) were analyzed to assess HR practices being practiced by insurance companies in India. Six factors from factor analysis were further analyzed. ‘Training and benefits’ was found highly in practice in the insurance companies. Further, ‘performance appraisal,’ ‘selection and socialization of employees,’ and ‘HR planning and recruitment’ were moderately practised in insurance companies. ‘Workforce diversity and contemporary HR practices’ and ‘competitive compensation’ were also practised to some extent. ANOVA results showed that Indian companies did not practise workforce diversity. Compensation practices were found more competitive or performance based in Multinational insurance companies than in Indian ones. The gender effect showed that only competitive compensation was perceived significantly differently by male and female employees/executives. Interactive effects were significant on workforce diversity and contemporary issues, training and benefits, and selection and socialization of employees.competitive compensation, multinational companies, performance appraisal, selection and socialization, training and benefits, workforce diversity

The Luminosity Functions of Old and Intermediate-Age Globular Clusters in NGC 3610

The WFPC2 Camera on board HST has been used to obtain high-resolution images of NGC 3610, a dynamically young elliptical galaxy. These observations supersede shorter, undithered HST observations where an intermediate-age population of globular clusters was first discovered. The new observations show the bimodal color distribution of globular clusters more clearly, with peaks at (V-I)o = 0.95 and 1.17. The luminosity function (LF) of the blue, metal-poor population of clusters in NGC 3610 turns over, consistent with a Gaussian distribution with a peak Mv ~= -7.0, similar to old globular-cluster populations in ellipticals. The red, metal-rich population of clusters has a LF that is more extended toward both the bright and faint ends, as expected for a cluster population of inter-mediate age. It is well fit by a power law with an exponent of alpha = -1.78 +-0.05, or -1.90+-0.07 when corrected for observational scatter. A Kolmogorov-Smirnov test confirms the significant difference between the LFs of the red and blue clusters, with a probability of less than 0.1% that they come from the same population. A comparison with the Fall & Zhang cluster disruption models shows marginal agreement with the observed LF, although there are differences in detail. In particular, there is no clear evidence of the predicted turnover at the faint end. A by-product of the analysis is the demonstration that, at any given metallicity, the peak of the LF should remain nearly constant from 1.5 Gyr to 12 Gyr, since the effect of the disruption of faint clusters is almost perfectly balanced by the fading of the clusters. This may help explain the apparent universality of the peak of the globular cluster luminosity function. (Abridged)Comment: 32 pages, LaTeX, 13 PS figures, 1 table; to appear in AJ (July 2002

Effect of realistic interatomic interactions and two-body correlation on the heat capacity of a trapped BEC

An approximate many-body theory has been used to calculate the heat capacity and the condensate fraction of a BEC with effective repulsive interaction. The effect of interactions has been analyzed and compared with the non-interacting case. It has been found that the repulsive interaction lowers the critical temperature from the value found in the non-interacting case. The difference between the critical temperatures increases with the increase in the total number of atoms in the trap.Comment: 15 pages, 5 figure

Biomimetic antibacterial pro-osteogenic cu-sericin MOFs for osteomyelitis treatment

Osteomyelitis is an inflammation of the bone caused by bacterial infection. It usually develops from broken bones, decayed teeth, or heavily punctured wounds. Multi-drug-resistant bacteria are the major hurdle in the treatment of osteomyelitis. The ever-rising antibiotic resistance even leads to amputations or fatalities as a consequence of chronic osteomyelitis. Hence, a single agent with antibacterial activity as well as bone regenerative properties can serve as a potential off-the-shelf product in the treatment of osteomyelitis. Herein, the antibacterial and pro-osteogenic characteristics of copper sericin (Cu-SER) metal–organic frameworks (MOFs) are reported. Sericin, a silk protein with antibacterial activity and an osteoinduction property, acts as an organic template for the deposition of Cu-SER MOFs, similar to collagen during biomineralization in bone. The MOFs exhibit cytocompatibility and osteogenic activity in a dose-dependent manner, as revealed by cell proliferation (alamarBlue) and mineralization (Alizarin Red S and Energy Dispersive X-ray analysis). The bactericidal activity of Cu-SER MOFs was investigated by scanning electron microscopy and a growth kinetic analysis. Together, the report illuminates the unique phenomenon of Cu-SER MOFs that kill bacteria upon contact while being well-tolerated by primary human cells. Hence, Cu-SER MOFs hold the potential to minimize antibiotic dependence.This work is supported by the European Union Framework Programme for Research and Innovation Horizon 2020 (No. 668983—FoReCaST) and the BREAST-IT project (PTDC/BTM-ORG/28168/2017) to S.C.K., funded by the Programa Operacional Regional do Norte supported by European Regional Development Funds (ERDF), Portugal

The Globular Cluster Systems in the Coma Ellipticals. III: The Unique Case of IC 4051

Using archival \hst WFPC2 data, we derive the metallicity distribution, luminosity function, and spatial structure of the globular cluster system around IC 4051, a giant E galaxy on the outskirts of the Coma cluster core. The metallicity distribution derived from the (V-I) colors has a mean [Fe/H] = -0.3, a near-complete lack of metal-poor clusters, and only a small metallicity gradient with radius; it may, however, have two roughly equal metallicity subcomponents, centered at [Fe/H] ~ 0.0 and -1.0. The luminosity distribution (GCLF) has the Gaussian-like form observed in all other giant E galaxies, with a peak (turnover) at V = 27.8, consistent with a Coma distance of 100 Mpc. The radial profiles of both the GCS and the halo light show an unusually steep falloff which may indicate that the halo of this galaxy has been tidally truncated. Lastly, the specific frequency of the GCS is remarkably large: we find S_N = 11 +- 2, resembling the central cD-type galaxies even though IC 4051 is not a cD or brightest cluster elliptical. A formation model consistent with most of the observations would be that this galaxy was subjected to removal of a large fraction of its protogalactic gas shortly after its main phase of globular cluster formation, probably by its first passage through the Coma core. Since then, no significant additions due to accretions or mergers have taken place.Comment: 24 pp. plus 13 Figures.
