Managing organizational knowledge while downsizing organizations

In this paper we investigate potential influence of organizational downsizing on organizational knowledge and learning. We discuss organizational downsizing in order to show that in large it is an issue of organizational design, and as such, managerial activity that must be coordinated with another - managing organizational knowledge. From this standpoint, we theorize that if these two managerial activities are not coordinated, organizational downsizing can lead to uncontrolled knowledge leakages, which can show to have unforeseen effects on organizational well-being in long term

Human Resource Management in the Countries of the Former Yugoslavia

Human Resource Management (HR/HRM) is closely connected to the social and economic environment in which a given organization or company operates. On this basis it may be interesting for foreign potential investors to understand both the differences and similarities in the application of HRM methods in a group of countries which had lived for a long period of time in a federation which had finally disintegrated. Such investors usually come from different environments and backgrounds and have previous experience in the application of specific forms of HRM practice. In this paper the authors try to present the development and changes in the theories and practice of Human Resource Management in most of the countries established on the territory of the former Socialist Federal Republic of Yugoslavia: Bosnia and Herzegovina, Croatia, Macedonia, Serbia and Slovenia.human resource management; economic environment; practices change; former Yugoslavia.

UTICAJ NAČINA PRESOVANJA NA PROMENE LEŠNIKOVOG ULJA TOKOM ČUVANJA I SENZORNA SVOJSTVA KEKSA

The changes in the spectrum, peroxide numbers and specific absorbances (at 232 nm and 270 nm) of fresh and storaged oils (4 months at 4 °C) obtained by different hazelnuts pressing were monitored. The results showed reduced viability of the oil obtained from the hazelnut exposed to elevated temperature during conditioning and pressing: changes in the spectrum about 290 nm, a peroxide number close to the legally allowed maximum (7.5 mmolkg-1) and possible presence of secondary oxidation products. Sensory evaluation of biscuits with hazelnut oil showed that the samples belonged to the categories of quality: very good and good. The overall sensory score was highest for biscuits with hazelnut oil pressed in an electric press.Publishe

Renal Infiltration of Follicular Lymphoma Folliküler Lenfomada Renal İnfiltrasyon

We present a case of renal infiltration of grade 3A follicular lymphoma (FL) mimicking renal cell carcinoma (RCC). Chronic renal failure (CRF) was diagnosed in a 63-yearold male during routine health controls. Ultrasonography results emphasized a left renal mass. Multislice computed tomography (MSCT) confirmed the prior findings of a solid multilobular mass (48x46x79 mm), reduced kidney parenchyma, and intact surrounding lymph nodes (LNs) mimicking RCC. Without previous oncological evaluation, urologists performed nephrectomy. Histopathology revealed FL of grade 3A, with perirenal infiltration. Immunohistochemistry was typical: CD79α+, CD20+, CD10+, MUM1-, Bcl-2+, Bcl-6+, cyclin D1-, CD23-, CD3, CD5-, CK AE1/AE3-, and EMA-, with a Ki-67 index of 20

Innovative optical method for sensing the nutritional stress in hydroponically cultivated plants

Well-balanced nutrition is important for the successful cultivation of healthy plants. In this paper, we demonstrate a nondestructive optical method that can sense a deficiency of certain nutrients. The setup was tested on hydroponically grown Ocimum basilicum. The plants were subjected to nutrient deficiency by the exclusion of one of the essential elements (Fe, Mg, P, N) from the hydroponic solution. A control group of plants, fed by the balanced hydroponic solution, was also grown under the same conditions. The proposed method tracks and records the optical transmittance of the plants' leaves. All groups exhibit clearly defined day-night Circadian rhythms. When compared to the control group, the treated plants exhibited modified circadian rhythms of the optical transmission, suggesting an early indicator of the plants' stress. The condition of the plants under test was also assessed by the more common (destructive) methods such as: measurements of the determination of the photosynthetic pigment content, dray weight determination and the efficiency of PSII. Several biological parameters were observed, calculated and compared to the graphs of optical transmission dependence in real time. Presented results have demonstrated a significant potential of the proposed optical method for the early detection of plants' stress in hydroponic cultivation

Crude bacterial extracts of two new Streptomyces sp isolates as bio-colorants for textile dyeing

Renewed demand for incorporation of natural dyes (bio-colorants) in textile industry could be met through biotechnological production of bacterial pigments. Two new Streptomyces strains (NP2 and NP4) were isolated for the remarkable ability to produce diffusible deep blue and deep red pigment into fermentation medium. Crude mycelial extracts of both strains were used as bio-colorants in conventional textile dyeing procedures avoiding downstream purification procedures. The yields of bio-colorants obtained in this way were 62 and 84 mg per g of mycelia for Streptomyces sp. NP2 and Streptomyces sp. NP4, respectively. Through nuclear magnetic resonance analysis of crude extracts before and after dyeing procedures, it was shown that both extracts contained prodigiosin-like family of compounds that exhibited different dyeing capabilities towards different textile fibers. Polyamide and acrylic fibers were colored to the deepest shade, polyester and triacetate fibers to a noticeable, but much lower shade depth, while cotton and cellulosic fibers stained weakly. These results confirmed that crude bacterial extracts had the characteristics similar to those of ionic and disperse dyes, which was consistent with the identified polypyrrolic prodigiosin-like structures
