The Cultural Differences Influences on Knowledge Sharing Activities in Construction Project Collaboration
In the last decades construction activity has been heavily criticized for its productivity and performance in relation to cultural differences. There have been several studies indicated that the cultural diversity influence the knowledge of the organization, and that result in barriers in knowledge sharing in the multicultural organization. The knowledge spreading manners affected by the cultural in organization due to ethnic, cities, sexual category, local culture, which that might lower level of the knowledge spreading in organization . Therefore, a research study is developed in order to assess the influences of cultural differences on the activity of knowledge distribution in organization project and to determine of extend of the cultural differences to obstacle the individual to share their knowledge within the organization or with other members of the organization and how is that leads to decrease the project's performance. For seeking to achieve the aims of the study a survey questionnaire was used to gather data. System dynamic simulation is utilized to interpret the collected data in order to achieve meaningful information. The results proven that cultural difference is one of the major problems that impact the project performance negatively in the construction industry since it is verified that the cultural difference impacts the knowledge flow among the employees in the construction project which that strongly affects the outcome of the projects and that also leads to decrease the productivity of the project. In addition, the respondents also agree that cultural differences cause unsuccessful safety system in the construction projects. Therefore, the cultural differences should be given careful attention to ensure better project performance
Decision support systems classification in industry
This research has presented a discussion of related literature on decision support systems (DSS) and its role in production systems. The first part of the research presents DSS and how this has evolved until 2010. The next part of the research provides a discussion of the decision making process and the data mining phases as these relate to DSS. The last part of the research presents further discussion of DSS and various perspectives on the criteria that could be used for DSS. The criteria in the classification of DSS includes the following: user relationship; orientation; scope of use; type and frequency of decision making; mode of assistance; focus area; objective; capacity; degree of guidance; and, degree of non-procedurality. The research also included a discussion of industry 4.0, which is known as the fourth revolution in the industry
Extraction techniques and industrial applications of jatropha curcas
The fact that Jatropha curcas oil cannot be used for nutritional purposes without detoxification makes its useful as energy or fuel source, which will improve the domestic economy and provide job opportunities particularly in rural areas, where mechanical pressing is currently the most extensively used process to extract oil from seed. In this context, the main goal of this study is to provide a summary of several studies dealing with the currently employed oil extraction technologies, the physicochemical properties of bio-oils obtained from J. curcas, and the potential uses of Jatropha oil. The aim is to shed light on the main differences among the four types of oil extraction techniques currently employed and to highlight their most appropriate applications. If tapped efficaciously, then these techniques could prove to be extremely helpful in these days of power and environmental crises
From 5G to 6G: Revolutionizing Satellite Networks through TRANTOR Foundation
5G technology will drastically change the way satellite internet providers
deliver services by offering higher data speeds, massive network capacity,
reduced latency, improved reliability and increased availability. A
standardised 5G ecosystem will enable adapting 5G to satellite needs. The
EU-funded TRANTOR project will seek to develop novel and secure satellite
network management solutions that allow scaling up heterogeneous satellite
traffic demands and capacities in a cost-effective and highly dynamic way.
Researchers also target the development of flexible 6G non-terrestrial access
architectures. The focus will be on the design of a multi-orbit and multi-band
antenna for satellite user equipment (UE), as well as the development of gNodeB
(gNB) and UE 5G non-terrestrial network equipment to support
multi-connectivity
GC-MS vs. GC-MS-MS analysis of pentacyclic terpanes in crude oils from Libya and Serbia - A comparison of two methods
The values of parameters calculated from distribution and abundance of the selected pentacyclic terpanes in crude oils from Libya and Serbia, which were originally derived from gas chromatography-mass spectrometry (GC-MS) were compared with results of quantification based on gas chromatography-mass spectrometry-mass spectrometry (GC-MS-MS). The parameters analyzed are the most often used terpane source and maturity parameters, which were applied to a large sample set of 70 oils, originating from five oil fields. The aim of the paper was to investigate to which extent the measurements of the selected parameters by these two instrumental techniques agree and to determine the influence of differences between parameter values on geochemical interpretation. For that purpose two methods, concordance correlation coefficient and mean-difference plot were used. The obtained results indicate that calculation of C(27)18 alpha(H)-22,29,30-trisnorneohopane/(C(27)18 alpha(H)-22,29,30-trisnorneohopane +C(27)17 alpha(H)-22,29,30-trisnorhopane), C(29)18 alpha(H)-30-norneohopane/C(29)17 alpha(H) 21 beta(H)-30-norhopane and C(29)17 alpha(H)21 beta(H)-30-norhopane/ C(30)17 alpha(H)21 beta(H)-hopane ratios either by GC-MS or GC-MS-MS do not significantly influence interpretation. On the other hand, the determination of C(30)17 beta(H)21 alpha(H)-moretane/C(30)17 alpha(H)21 beta(H)-hopane ratio, gammacerane index and oleanane index by GC-MS vs. GC-MS-MS could notably affect interpretation. These differences can be explained by the co-elution and the peak overlapping in GC-MS but also by better separation, higher precision and better selectivity of the GC-MS-MS. Deviation of the almost all studied parameters from the line of equality was similar for the oils from the same oil field but some differences were observed for the oils from different oil fields. Therefore, when GC-MS-MS results are to be used in organic geochemical interpretations, a regional calibration of GC-MS vs. GC-MS-MS relationship for each petroleum system is highly recommended
The Role of Individual Variables, Organizational Variables and Moral Intensity Dimensions in Libyan Management Accountantsâ Ethical Decision Making
This study investigates the association of a broad set of variables with the ethical decision making of management accountants in Libya. Adopting a cross-sectional methodology, a questionnaire including four different ethical scenarios was used to gather data from 229 participants. For each scenario, ethical decision making was examined in terms of the recognition, judgment and intention stages of Restâs model. A significant relationship was found between ethical recognition and ethical judgment and also between ethical judgment and ethical intention, but ethical recognition did not significantly predict ethical intentionâthus providing support for Restâs model. Organizational variables, age and educational level yielded few significant results. The lack of significance for codes of ethics might reflect their relative lack of development in Libya, in which case Libyan companies should pay attention to their content and how they are supported, especially in the light of the under-development of the accounting profession in Libya. Few significant results were also found for gender, but where they were found, males showed more ethical characteristics than females. This unusual result reinforces the dangers of gender stereotyping in business. Personal moral philosophy and moral intensity dimensions were generally found to be significant predictors of the three stages of ethical decision making studied. One implication of this is to give more attention to ethics in accounting education, making the connections between accounting practice and (in Libya) Islam. Overall, this study not only adds to the available empirical evidence on factors affecting ethical decision making, notably examining three stages of Restâs model, but also offers rare insights into the ethical views of practising management accountants and provides a benchmark for future studies of ethical decision making in Muslim majority countries and other parts of the developing world
