Managing Knowledge Workers for Change Management Dimensions

The knowledge economy requires a different contribution from human capital (i.e. knowledge workers). Knowledge workers are challenge seekers, have high enthusiasm for learning and prefer freedom and flexibility, so it would be wise to suggest that knowledge management should consider all these issues and try to provide opportunities to fulfill the current needs of knowledge workers in particular and the company in general. This paper aims to focus on how Knowledge Management practices, to make useful to change management.  This study suggests that training was one of the most important factors for initiating knowledge management, together with support from the top management. Besides that, compensation and rewards, as expected, remain the preferred factors encouraging knowledge workers to share their knowledge and stay in the company. Therefore a more competitive compensation and rewards package should be offered specifically for workers, compensation packages that more fully appreciate knowledge workers’ knowledge and skills would be most welcomed. This may be become a key factor for change management adoption as one of the dimension. Keywords: Knowledge Management, Knowledge Worker, Change Management, Leadership, Innovative Knowledg

Ferromagnetic to spin glass cross over in (La,Tb)_{2/3}Ca_{1/3}MnO_{3}

In the series La_{2/3-x}Tb_{x}Ca_{1/3}MnO_{3}, it is known that the compositions are ferromagnetic for smaller values of x and show spin glass characteristics at larger values of x. Our studies on the magnetic properties of various compositions in the La_{2/3-x}Tb_{x}Ca_{1/3}MnO_{3} series show that the cross over from ferromagnetic to spin glass region takes place above x ~ 1/8. Also, a low temperature anomaly at 30 K, observed in the ac susceptibility curves, disappears for compositions above this critical value of x. A mixed phase region coexists in the narrow compositional range 0.1 <= x <= 0.125, indicating that the ferromagnetic to spin glass cross over is not abrupt.Comment: 5 pages, 5 figure

Thermomagnetic history effects in SmMn2_2Ge2_2

The intermetallic compound SmMn$_2$Ge$_2$, displaying multiple magnetic phase transitions, is being investigated in detail for its magnetization behavior near the 145 K first order ferromagnetic to antiferromagnetic transition occuring on cooling, in particular for thermomagnetic history effects in the magnetization data. The most unusual finding is that the thermomagnetic irreversibility, [= M$^{FCW}$(T)-M$^{ZFC}$(T)] at 135 K is higher in intermediate magnetic field strengths. By studying the response of the sample (i.e., thermomagnetic irreversibility and thermal hysteresis) to different histories of application of magnetic field and temperature, we demonstrate how the supercooling and superheating of the metastable magnetic phases across the first order transition at 145 K contribute to overall thermomagnetic irreversibility.Comment: 15 pages, 5 figures, to appear in Physical Review

Size-dependent magnetic properties of nanocrystalline yttrium iron garnet powders

Yttrium iron garnet (YIG) powders with particle sizes of 9, 14, 25 and 60 nm have been synthesised and their magnetic properties have been studied as a function of particle size and temperature. The particles with sizes of 9 and 14 nm exhibited superparamagnetism. The blocking temperature (T-B) decreased with decreasing particle size, whereas the anisotropy constant (K) increased. The saturation magnetisation (M-s) decreased with decreasing particle size. These variations are attributed to large surface-to-volume ratios in nanoparticles where the surface moments are predominant. (c) 2005 Published by Elsevier B.V

Effect of Corporate Social Responsibility on Financial Performance in Nigeria

The study examined corporate social responsibility on financial performance of banks in Nigeria by using earning per share, gross earning and profit after tax as measures of financial performance of banks in Nigeria. The study design was ex-post-facto. Pearson correlation and simple regression analysis were the major statistical tools used for the analysis through the application of SPSS version 20.0 and E-View 8.0 software packages. Correlation results showed that whereas the relationship between corporate social responsibility and earning per share was positive but insignificant, it showed strong, positive and significant relationships with gross earning and profit after tax respectively. Similarly, corporate social responsibility expenditure was found to have insignificant effect on earnings per share, it has significant effect on gross earning and profit after tax of the banks in Nigeria. The study recommends among others that corporate organizations should endeavor to give more to the society in CSR and leverage it to enhance the financial performance of their businesses in the country

468-472Ultrafine titania (TiO2) spherical powders have been prepared by controlled hydrolysis of titanium tetrabutoxide in presence of acetic acid/acetone solution. The powder X-ray diffraction shows that the as-dried precursor is crystalline in nature and shows broad peaks corresponding to hydrous titania (anatase) phase. The calcination of the hydrous titania precursor at 350°C/2hr under controlled conditions produces agglomerated spherical anatase titania powders (size 200nm) with improved crystallinity. These microporous agglomerates are found to be constituted of 14 nm primary anatase particles. These powders show high surface area (105 m2/g) as measured by BET technique.</span
