A study on the effect of workaholism on human resource productivity: A case study of managers of East Azerbaijan Water and Waste Water Company

These days, work is considered as an integral part of the human life and many people spend significant amount of their time in different organizations and departments to earn income. Unlimited organizational pressures and demands facing people have made them allocate much of their time on working. Because of these pressures, people are becoming increasingly subject to workaholism. On the other hand, leaders and managers are trying to improve performance and activities of their respective organizations. Therefore, different concepts such as productivity are turned to the major subject of the management and organizational studies within the same organizations. Note that today changeable and competitive environment and the available limited resources and facilities have turned the concept of productivity into one the most important preoccupations of management within modern organizations. In view of the limited studies and information available in Iran on workaholism and its adverse consequences, the present research intends to investigate and identifies the impacts of workaholism components on human resource productivity. In the present, research the descriptive-survey research method is used and where statistical community includes 130 managers of the East Azerbaijan Water and Waste Company. Using the correlation coefficient and linear regression technique the research tries to investigate the relationships between the concepts of workaholism and human resource productivity and demonstrates how they are applied in above-mentioned community

Penerapan Algoritme Logika Fuzzy Untuk Dynamic Difficulty Scaling Pada Game Labirin

Mayoritas pemain baru dalam sebuah game cenderung asal dalam memilih level. Hal ini menyebabkan terjadinya imbalance pada permainan, yang membuat game menjadi terlalu mudah atau bahkan terlalu susah. Untuk mengetahui tingkat kemampuan dan level, maka diperlukan suatu input dari pemain sebagai parameter yang digunakan untuk proses menentukan tingkat kesulitan pada game. Dalam menangani masalah tersebut, maka dalam penelitian ini akan dilakukan penerapan implementasi dengan metode fuzzy dalam membuat Dynamic Difficulty Scaling untuk memberikan balance level dalam game labirin. Metode pengujian yang dipakai meliputi pengujian validasi behavior dan performa dari permainan. Pengujian validasi behavior dilakukan dengan cara mencari 5 orang relawan dalam menguji permainan untuk melihat hasil keluaran next level labirin yang muncul serta menganalisis hasil dari balance level yang terjadi. Hasil dari analisis yang dilakukan yaitu metode fuzzy ini berhasil untuk menyetarakan softskill yang dimiliki pemain dengan level yang dimainkan. Sedangkan pengujian performa dilakukan dengan cara menguji besarnya frames per second (fps) yang dihasilkan selama permainan. Hasil menunjukkan bahwa performa terbaik terdapat pada map dengan ukuran 5x5 sebesar 107,22 FPS, serta performa terburuk terjadi pada labirin dengan ukuran 50x50 yang memiliki 87,65 FPS. Dari hasil pengujian performa tersebut dapat diketahui bahwa permainan ini layak untuk dimainkan mengingat batas minimum kelayakan FPS untuk permainan dikategorikan layak untuk dimainkan adalah 30 FPS

Exploring into Graduate Research Term Papers: A Quest for Generic Disciplinary Tendencies

The purpose of this exploratory analysis was to capture students’ generic tendencies in the organization of original research term papers written by graduate within the same linguistic, cultural, and disciplinary territory. A model proposed by Sheldon (2011) was benchmarked against a corpus of 60 English research term paper introductions to identify the saliency of move schemes along with step and sub-step realizations. At step-level analysis, the proportion of the various steps within Move 2 (indicating a gap, adding to what is known, and presenting positive justification) exhibited a pervasive lack of rhetorical tendency that contradicted the previous genre-based findings. Such an exploration, offers implications for English for research publication purposes instruction and academic literacies based on academic conventions and norms

Oil Reservoir Permeability Estimation from Well Logging Data Using Statistical Methods (A Case Study: South Pars Oil Reservoir)

Permeability is a key parameter that affects fluids flow in reservoir and its accurate determination is a significant task. Permeability usually is measured using practical approaches such as either core analysis or well test which both are time and cost consuming. For these reasons applying well logging data in order to obtaining petrophysical properties of oil reservoir such as permeability and porosity is common. Most of petrophysical parameters generally have relationship with one of well logged data. But reservoir permeability does not show clear and meaningful correlation with any of logged data. Sonic log, density log, neutron log, resistivity log, photo electric factor log and gamma log, are the logs which effect on permeability. It is clear that all of above logs do not effect on permeability with same degree. Hence determination of which log or logs have more effect on permeability is essential task. In order to obtaining mathematical relationship between permeability and affected log data, fitting statistical nonlinear models on measured geophysical data logs as input data and measured vertical and horizontal permeability data as output, was studied. Results indicate that sonic log, density log, neutron log and resistivity log have most effect on permeability, so nonlinear relationships between these logs and permeability was done

Identification and ranking of factors affecting behavioral economics in Iran

Purpose- Since economics is the science of choice and if we conside the human being as a selector, it should be noted how the function of selection is formed and how it can psychologically measure and analyze activities such as intentions, motives, opinions, attitudes and expectations. The aims of this study were to identify and rank the factors affecting behavioral economics and its use. Design/methodology/approach- In this deseriptive -analytic study, 385 in dividuals were selected using the Cochran formula. Data were gathered through a questionnaire and analyzed using arachnoid diagram rating and spss software package. Findings- Generally, fairness, risk and inequity aversion dimensions have more important roles in behavioral economics of Iran community, while, mimicry, sel fishness and economic intelligence have less significant roles. All hypotheses of the study were confirmed (p<0.05) and although the hypothesis related to selfishness was rejected, according to the participants, role of selfishness dimen-sion is high among Iran community. Research limitations/implications- It can be concluded that the behavior and habits of other people have no significant role in behavioral economy of Iran community, that might be due to the fact that the effects of these two items on economy is not so important; hence respondents don’t consider high amount of significance for these dimensions in Iran community. More over, in behavioral economics of Iran community the amount of reciprocal friendship, inequity aversion and fairness is low that can be attributed to the lack of trust between people in regard to their economic decisions. Practical implications- One of the most important applications of this research, is offering behavioral economy in general scheme, and as regards to few research in this field, it’s one of the main prob-lems of executives when refer to this field of science, because they don’t have appropriate image of the current situation in Iran and by this image they will be able planning decisions regarding the strengths and weaknesses of Iranian society. Originality/value- Firstly, similar research in the field of behavioral economics has not been carried out in Iran, and this study can be considered grounds for starting research in this field. Furthermore, dispite the long time has passed, since the introduction of behavioral economics theory , no research has been focused on this issue in Iran and presented profile in this research , is the first image of be-havioral economics in Iran.
