Ecological and Evolutionary Dynamics of Aresian and Erosian Economy (pp. 1-12)

Imre Lazar
In this paper we explore the ecodynamics of economic transformation of Central-East –European late socialist industries under the pressure of globalization. We use both term ARES and Eros in allegoric sense and as an acronym of Accumulation, Risk, Environmental degradation In this framework we deconstruct the process of the neoliberal transformation of local economies. Deconstruction of informational, technological and social dynamism also helps to reveal the hierarchical ranks of the four environmental actors feedingt the ARESian dynamics of contemporary economical and social phenomena.

The Role of E-Procurement in the Austrian Construction Industry: Adoption Rate, Benefits and Barriers (pp. 13-21)

Bernd Zunk, Martin Marchner, Iris Uitz, Carina Lerch, Holger Schiele
The progressive developments force suppliers on efficiency-driven construction markets to reorganize their internal organization. Especially the complex and not standardized procurement process holds high cost reduction potential. To exploit this potential, suppliers need to understand the purchasing routines of their buyers. Hence, a rising number of supplying firms consider e-procurement solutions to foster and to optimize the direct link to their buyers. The central question of this contribution concerns the role of e-procurement in procurement processes of industrial buyers and reports the results of a respective survey study among 100 construction firms in Austria. The survey study focuses on the adoption rate of e-procurement solutions as well as the used functions and software solutions. Furthermore, benefits and barriers of buyers in the construction industry for using e-procurement systems are highlighted. The findings show that e-procurement is not frequently adopted in the construction industry and that the potential for cost reduction is not exploited to the full.

The Paradigm Shift? - Rosia Montana between Industrialization and Post-Industrialization (pp. 23-28)

Maftei Stefan-Sebastian
The paper will try to argue that the Roşia Montană protest phenomenon in Romania is significant for two main reasons. First, that this protest movement may have changed the nature of civic involvement in post-Communist Romania, especially with reference to the levels of participation and the new participatory environments. Second, that the Roşia Montană civic phenomenon may have also contributed, directly or not, to the changing of the paradigm of thinking economic processes in post-communist Romania, from a developmental approach to a post-industrial approach.

Deindustrialization: Why Would Anyone It Is a Myth (pp. 29-38)

Alpar Losonc, Andrea Ivanisevic
In this paper work we assemble the mosaic: we started with deindustrialization in the (negative) perspective of employment dynamics. We contextualized it here with indications of divergence between productivity and employment; it turned out that the productivity dynamics was not synchronized with the wage trends i.e. that the productivity is tied to significant asymmetry of distribution of productivity results. Deindustrialization occurs nowhere else but in this context; namely, in groups of different tendencies or, if we use our methodological projection, deindustrialization may be placed in the context of cumulative causal chains. Talking about deindustrialization without contextualizing shall not give us deeper explanations. Therefore, this is data that is worthy of full attention and do not allow us to get rid of the burden of speaking about deindustrialization too quickly. So, if we sum up everything said in this section, we may say and be able to see later as well, that there are certain differences, but globally speaking, there is no deindustrialization as a one-line process in terms of absolute drop in industrial employment.

Gender Differences in Expressing the Job Satisfaction Among Scientists (pp. 39-44)

Zeljka Bojanic
On a sample of 400 respondents, consisting of scientists working at the University of Novi Sad, a study was conducted by means of an on-line questionnaire based on the theoretical concepts of Herzberg’s two-factor theory of motivation, with the aim of testing the attitude of scientists towards their job satisfaction. The starting point in the study is the expectation that there is a significant correlation between the human capital features and job satisfaction at the institutions of higher education of the University of Novi Sad. Job satisfaction of researches has been measured with regard to the gender of respondents. The method used to demonstrate the differences in attitudes of scientists in job satisfaction with regard to their gender was method of variance analysis. According to the study, when considering gender and job satisfaction according to gender, the results indicate that men demonstrate a higher degree of job satisfaction compared to women. The male respondents surveyed are more satisfied with their job than their female colleagues, in terms of advancement, amount of salary and overall appreciation of them as professionals. Female scientists are of the opinion that they are not adequately rewarded for the tasks they perform. Additionally, they are dissatisfied with the conditions in respect of the personal promotion and professional advancement at the faculty. They do not consider being good at one’s job a necessary prerequisite for promotion. This study has substantiated the results indicating that there are more male than female PhD title holders. Due to a range of obligations ahead of women (such as marriage, family, children), they find it more difficult to harmonise their personal and professional life.

Role of Drought Early Warning and Social Planning in Industrial Growth (pp. 45-51)

Anna Frank, Richard Frank, Ljiljana Popovic
This paper presents challenges on industrial growth planning. A component of population change is dynamic in time and space, and has more dynamic components such as psychological, human preparedness, education level, and the most important one, which is the percentage of the population that is most vulnerable. Population change can influence growth due to the lack of trained and educated personnel, a rise of pressure on industrial sectors and variation in wages. The reason for this lies in the dependence relationship between the percentage of the working population and the other aspects of society such as the percentage of most vulnerable within the population and issues like population change. Industrial growth planning also depends on environmental issues and available resources. Climate change and climate extremes influence the availability of resources, especially water in case of drought. In all times the most important resource of all is water which has to be spread between different sectors and users wisely. Industrial development relies on good planning and proper management of all resources, natural and human.

Mechanism and Effect of Mallet Tapping on Contact Stress Distribution Between V-band Clamp and Piping Systems (pp. 53-60)

Zhengui Zhang, Haiyan H Zhang, Peixuan Wu
This paper is dedicated to investigate the mechanism of mallet tapping on the equalization of contact pressure distribution between V-band clamp and piping system. A sensor platform with charge mode amplifier is built to collect quasi-static measurements of contact pressure during loading. Contact pressures in the initial stage before and after mallet tapping is measured using piezoelectric sensor tests. Finite element analysis (FEA) is carried out to find the initial contact areas. The controlled measurement verified the viability of mallet tapping on contact pressure redistribution. In terms of clamping stability, the effect of mallet tapping is discussed from the working principle of Vibratory Stress Relief (VSR). Dynamic analysis is also tried to explore the mechanism of mallet tapping on equalizing the contact pressure distribution. The frequencies of clamp are estimated by theoretical calculation and experiment tests, which are applied to derive the mode of vibration wave after mallet tapping.

Financial and Human Benefits of Lean Production in the Plastic Injection Industry: an Action Research Study (pp. 61-75)

Vitor Resende, Anabela C. Alves, Alexandre Batista, Angela Silva
This paper presents the results of a Lean Production project implementation developed in a plastic injection company. The main aim of the project was the application of Lean principles and tools involving the stakeholders of the company. The first tool applied was the VSM to diagnose the production system and to identify the wastes and the main issues for improvement. Some proposals were presented and implemented using Lean tools such as 5S, PDCA cycle, Kanban, SMED and Kaizen. Some tangible and financial results obtained were an increase of productivity of the assembly lines by 12%, of the operating income by 6%, a reduction of the cycle time of six dies to 10% and a reduction by 15% of tool changeover time and an increase of total incomes estimated in €360,000.00. Intangible results were the operators’ engagement and involvement with the continuous improvement and with Lean implementation.

Priority Analysis on the Reliability Parameters of an Existing Model (pp. 77-84)

Seyed Hossein Khodaei, Masoud Rahiminezhad Galankashi, Adnan Hassan
The basic goal of this paper is to create an alternative based analysis in a reliability model. Despite the vast amount of studies on reliability analysis and related techniques, the evaluation of the importance of different alternatives is less investigated. In order to fill this gap, this research was carried out to systematically investigate the result of setting three different scenarios on a reliability model. A model of reliability system was proposed based on redundancy allocation problems. There are certain limitations (Weight and Cost)of proposed model. In particular, three different scenarios (the results of Failure Rate preference, Weight preference and Cost Preference) was presented. This investigation operated based on the assumption of allocating only one redundant component for the subsystems, and the main goal of this investigation is to determine what would be the results when lowest possible Weight, lowest possible Cost and lowest possible failure rate is needed.

A Visual Board to Facilitate Production Flow Regulation at Sequential Processes (pp. 85-94)

Goh Wen Jiun, Chin Jeng Feng, Shahrul bin Kamaruddin, Nur Amalina binti Muhammad
A visual system allows one to assess the production status of a shop floor at a single glance and detect abnormalities like deviations from the production plan. This paper presents a case study of a visual system application on an electronics backend assembly that consists of several mixed-model sequential processes. The production flow is regulated by a push system. Isolated scheduling at the front end significantly contributes to erratic arrival of parts at the backend. A generic visual board was designed and implemented to avoid significant inventory build-up, shorten average flow time, and ensure maximum production leveling. The visual board is named as visual Work-in-progress (WIP) flow monitoring board and is described in terms of its physical appearance, component functions, and operating procedures performed by different levels of staff. The paper also includes the implementation of the visual board and performance evaluation after ten months of execution. The system was found to produce positive results.
