    Politics in organizations is an important aspect of organizational life which has been an interesting research area since last four decades. However, it is still deprived of practical approach due to its inconclusive studies and fragmented arguments. In politicized organizations, morale and motivation of employees depend mostly on their type of exchange relationships. The study in hand is another effort to view these exchange perceptions as intervening between the relationship of perceptions of organizational politics and morale of employees. As a part of larger study, data was collected through self administered questionnaire distributed among master of business administration students who were completing their management degree as part time along with their jobs during day time. All the Pakistani business schools were included in this study and surveys were distributed to 2000 employees during their classes and participation was voluntary ensuring anonymity and compliance with ethical considerations. Overall, 2000 questionnaires were distributed among which 1163 useable surveys were returned after screening and cleaning for unengaged response, left over pages and missing critical information. Thus response rate was 58%. Results of regression analysis indicated that social exchange perceptions was partial mediators in the relationship between perceptions of organizational politics and employee morale  and about 70% of the total effect was mediated by these perceptions which was an important indicator for understanding organizational life. Practical policy implications have also been discussed in discussion sections along with limitation of the study and guidelines for future research

    Groundnut is one of the largest vegetable oil and has a good nutritional value. It could be used as an alternative source of food, industrial raw materials, and bioenergy. The main function of fats and oil in seeds reserves source of energy. This research aims to study the diversity of morphological, yield, and the oil content in groundnut germplasm. The planting of groundnut was conducted at the experimental station Cikeumeuh BB Biogen Bogor from July until December in 2013, with the germplasm of groundnut as much as 200 accessions. The characters identification is determined by the method of morphological characterization with Groundnut Descriptor from IPGRI. Analyze oil content of groundnut used soxhlets method at the Laboratory of Post-harvest Bogor. The results showed that germplasm groundnut have varied levels of diversity at characters. Relatively high morphological diversity founded the character of pod yield/plot, weight of pods/plant and number of immature pods. Groundnut oil content is range 33% to 47%. There are a real positive correlation between the number of pods to variable morphology, yield and oil content, but negatively correlation at weight of 100 seeds. Number of pods and number of branches is positively correlation with oil content of groundnut seeds. Cultivars groundnut that have the characters of promise could be used as national asset and the source of genes as a parent in the breeding program

    The Relationship Between the Components of E-Government Services Towards Corruption in Malaysia and Indonesia

    This study investigates the correlation between the components of e-government services and corruption levels in Malaysia and Indonesia. Both countries have implemented various measures, including advanced e-government platforms and public participation, to combat corruption. However, instances of corruption have not shown a significant decline in either country. A total of 240 questionnaires were distributed to respondents from various sectors, including government, entrepreneurs, academia, non-governmental organizations (NGOs), and the media, in Indonesia and Malaysia. The Mann-Whitney U test was utilized to compare e-government services and corruption levels between the two countries. Interestingly, the results indicate variations in the e-government models adopted in Indonesia and Malaysia. In Malaysia, Government-to-Government (G2G) and Government-to-Citizen (G2C) interactions demonstrate a significant impact on corruption levels. In contrast, in Indonesia, Government-to-Business (G2B) and G2C interactions exhibit significant effects on corruption. Keywords: e-government, Government to Government (G2G), Government to Business (G2B), Government to Citizenship (G2C), anti-corruptio

    Characterization of wide cross derivatives in rice Oryza sativa L. using genomic in situ hybridization (GISH)

    Get PDF
    Interspecific crosses provide a bridge by which the gene pool of rice can be increased. Introduction of alien genes requires hybridization followed by meiotic pairing and recombination between the chromosomes of cultivated and wild species. Attempts have been made to visualize the genomic constitution of wide-cross derivatives. Genomic in situ hybridization was used to detect Oryza australiensis chromosomes and introgressed segment from O. australiensis into the Oryza sativa background. Genomic DNA from O. australiensis was labeled with biotin-14-dATP and hybridized to the homologous chromosomes in hybrids, back cross progenies, monosomic alien addition line (MAAL) and introgression line. The probe hybridization fluoresced green and non-labeled O. sativa chromosomes appeared red due to counterstaining with propidium iodide (PI). This differential painting of chromosomes unequivocally detected the O. australiensis chromatin introgressed into the O. sativa genome. The probe produced uniform labeling pattern over the entire length of all the O. australiensis chromosomes. Genomic in situ hybridization (GISH) detected 12 O. australiensis chromosomes in the hybrid, O. sativa x O. australiensis in BC1 progenies, and a single chromosome in MAAL. Small segment of O. australiensis was localized on the chromosome 12 of the introgression line. However, results showed that GISH is a powerful technique to be used as an aid in selecting segregating progenies.Key words: Genomic in situ hybridization, wide hybrid, localizing introgression

    This paper presents the experimental investigation of the characterization of the narrowband on-body radio propagation channel at 2.45 GHz. Wearable planar textile monopole antennas (TM) were used in this measurement campaign. The measurements were conducted in the RFshielded room environment, considering eight on-body radio links. A statistical analysis was conducted on the spectral parameters of the channel to enable the prediction and modeling of dynamic on-body radio propagation characteristics. The empirical data were fitted to several wellknown statistical models to determine the model that provided the best fit for the data. The results showed that the path loss exponent was consistent with the results of previous studies. The results also demonstrated that lognormal distribution was found to be the best fit for path loss in dynamic on-body radio propagation channel

    This paper attempts to examine the impact of adopting multiple family ownership cut-offs in defining family businesses, family ownership measurements, and conducting differen types of analyses.For achieving this goal we have focus on the relationship between family ownership and firm performance (ROA) in the context of emerging market (Saudi Arabia), controlling for firm's debt, age, size and industry sectors, with three family ownership cut-offs: 5%,10% and 20% and two types of family ownership measures (ratio and dummy), we fond that the relationship between the two variables is consistent despite of the level of family ownership cut-off, analysis type, and measurement.This indicates that family business definition is not a matter of concern for researchers, but rather a matter of convenience

    Family involvement in ownership, management, and firm performance: Moderating and direct-effect models

    Get PDF
    This study aims to provide an empirical evidence on the moderating effect of family involvement in management(family CEO and founder CEO) on the relationship between family ownership and firm’s performance. From a sample of 75 public listed companies (375 firm-year observations) in Saudi Arabia, we use a five-year interval (2007-2011) and two firm performance indicators (market to book value (MBV) and return on assets (ROA)) to test five hypotheses.The hypotheses that there is a direct impact of family ownership and founder CEO on ROA and MBV were supported respectively.The hypothetical moderating impact of family CEO and founder CEO have been partially confirmed with MBV.Overall, the findings highlight the importance of occupying CEO positions in family firms by family members, especially the founders for gaining better performance.However, the results are robust when only family firms are examined separately
