Job Analysis System for Civil Engineers in Construction Companies

Job research and analysis studies are the reports that detail the system andenvironmental conditions and performance of each job for obtaining higher efficiency andreducing the unit cost. In order to do the job analysis properly, information and data regardingthe job have to be evaluated accurately and realistically. The originating point of the article isbased on this definition and requirement. In the study, the established job analysis model hasbeen built on system approach. Steps of the model consist of input-preliminary preparation,process-analysis and conclusion phases.In accordance with the model suggested, a job analysis form has been developed to beused in improvement of functions of various human resources and in selection of civil engineersat manager position of construction companies during the study. The form specifies the jobprofile and personal requirements of civil engineers and gives information about time researchstudies aimed at efficiency. Form data has been collected by interviewing 50 (fifty) civilengineers at manager position working at large and medium sized construction firms, in order tobe used in job analysis discipline. In the study, information and data obtained by job analysisform have been analyzed by statistical methods and the results have been compared to similarliterature findings

Crisis management in Turkish construction industry

Various economical crises have affected Turkish economy during the last decade and construction industry has always been among the hardest hit; giving the idea that a comprehensive approach to crisis management is unavoidable. However, literature showed no findings related with crisis management applications by construction companies. Thus, a questionnaire survey was undertaken by the top management of 120 construction companies to investigate the degree of crisis management applications throughout the industry, mainly focusing on the outcomes during the economical crisis in 2001. Frequency analysis, Likert scale of comparison, Thurstone's paired comparisons, Pearson's chi-square test and Fisher's exact test were used to evaluate the results. The results showed that government policies and instable market conditions were the most important causes of crisis for Turkish construction companies. Meanwhile, only a small number of the companies utilized a systematic crisis management and the extent of crisis management applications varied depending on the size and the structure of the companies. Consequently, panic and powerlessness were the common feelings shared throughout the industry during the economical crisis in 2001. Despite, it was still encouraging that the managers utilized contemporary decision-making methods to get out of the crisis and their final decisions were generally in favour of strategically repositioning themselves. © 2005 Elsevier Ltd.

JIT in developing countries-a case study of the Turkish prefabrication sector

Just in Time (JIT) is a production management system, whose success depends on the fulfilment of a number of environmental conditions; which presents the problem related with its applicability in developing countries. The literature shows that the poor supply and demand conditions, and the unstable economic environments are the main obstacles for JIT application in developing countries. Other factors include; high costs of; imported technology, training, maintenance and the quality systems, low costs of labour and, the cultural values based on both high power distance and uncertainty avoidance. The Turkish prefabrication sector was analysed as a case study. A questionnaire survey and a number of interviews were undertaken with Turkish prefabrication companies. Frequency, Thurstone's Paired Comparisons and correlation coefficient analysis were used to evaluate the questionnaire results. The results unexpectedly showed that inflation was not an obstacle against implementation of JIT by Turkish prefabrication companies, as it had a trivial effect on the companies' supply-chain policies. Additionally, unlike in most developing countries material supply conditions were satisfactory. The financial difficulties and the demand uncertainties were determined to be the main obstacles for the implementation of JIT in the Turkish prefabrication sector. © 2003 Elsevier Science Ltd.

Mobbing on construction professionals: causes, consequences, and precautions

Mobbing is a negative attitude and behaviour that may be exhibited by superior(s), subordinate(s), or equal(s) to the victim(s) in a workplace. The primary purposes of this kind of action are to passivate, frustrate, and finally send the victim away from the workplace. This study investigates the causes and types of mobbing in the construction industry, the perception, and reaction of construction professionals about mobbing and the effects of mobbing on victims’ families and social lives. A questionnaire was applied to 664 construction professionals. Collected data were analyzed by using frequency/percentage analysis, The analysis of variance (ANOVA), Thurstone paired comparisons judgments (TC), Pareto method and cross-tabulation analysis. The results show that the construction professionals are aware of the concept of mobbing, but not their rights. Intention to suppress the victim (by the superior), or jealousy/envy (by the subordinates or equals) are the essential reasons for mobbing. Besides, gender discrimination, egoism against female professionals and disagreement in political views are vital factors that lead to mobbing. As a result, professionals exposed to mobbing experience psychological disorders. To avoid mobbing, individuals and companies should develop mobbing prevention and dissuasion strategies such as support from specialists, training and awareness-raising activities. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group

Industry financial ratios-application of factor analysis in Turkish construction industry

Turkish economy has been hit by various economical crises between the years 1998 and 2001 and the economic stagnation still continues. Past experiences in various countries show that it is vitally important to encourage construction activities in order to get out of stagnation, as construction output directly affects about 200 other sectors and industry financial ratio analysis is a means to provide a basis for the governments to undertake corrective action. However, there are over 50 financial ratios that can be used during analysis and some are more important than the others for different industries. Previous research has shown that there are about 25 factors that are important for the construction companies. This, in turn, requires elimination of unrelated data. Factor analysis is a data reduction and classification technique, which can be applied in financial analysis. Factor analysis was thus applied to the financial data collected from Turkish construction companies for a 5-year period in order to determine the financial indicators that can be used to analyse the financial trend of the industry. Five independent factors, i.e. liquidity, capital structure and profitability, activity efficiency, profit margin and growth, and assets structure were identified to be sensitive to the economical changes in the country. The results of the factor-based analysis can be used both by the government to analyse the changes in the industry with respect to time and by the construction companies to analyse their financial state with respect to their rivals. © 2005 Elsevier Ltd.

Relationships between hypoxia induced factor-1 alpha and F-18-FDG PET/CT parameters in colorectal cancer

Conclusion: Although the presence of a positive correlation between tumour SUVmax and %TmNcr shows that there are hypoxic cells in cancer tissue with high FDG uptake, the relationship between the presence of HIF-1 alpha and enhanced glucose metabolism and pathological prognostic factors of tumour was not shown. Strong nuclear immunohistochemical staining in tumour cells adjacent to invasive border and inflammatory cells leads us to believe that HIF-1 alpha plays a role in the invasion area of tumour microenvironment.
