Can Managerial Narcissism which Likely Leads to a Chaotic Process Be Measured?
Authors: Erçetin Şefika Şule , Hamedoğlu Mehmet Ali , Açıkalın Şuay Nilhan
Published: July 2014

Chaos is a source of life and also a reality for organizations and people as living and self-organizing systems. Management theory also deals with the internal struggle present in a tense, nervous person, and that such a person's attempts to organize and control the world are actually attempts to control and organize him/herself. Narcissistic leaders can both positively and negatively influence organizations. In chaotic situations, how do leaders manage chaos according to managerial narcissism point of view? This chapter aims to find an answer to the question of how managerial narcissism affects organizations, and how this effect can be measured. To answer this question, a scale of managerial narcissism was developed. In the two stage scale we developed for Managerial Narcissism, it can be seen that there are strong, positive relationships between each sub-dimension and that all dimensions are related to each other. In other words, the scale is well suited to measure how managerial narcissism affects an organization.

For this purpose, the authors discuss how one ought to handle uncertainties within Fuzzy Logic. Furthermore, they present recent advances in Type 2 fuzzy system studies.
Key Concepts in General Theory of Management in Innovative Society
Authors: Ponukalin Aleksei
Published: July 2014

The features of the modern world community in its transition to a phase-risk existence represent a socio- economic study on developing a model of an innovative society that is adequate to the conditions of the global crisis. A key problem of long-term development is the development of man, his social and natural environment but the key subjects of long-term planning are an innovative development and new quality of human capital since the quality of human capital is one of our competitive advantages. The economy must be innovative and the innovative economy must be created by “the innovative” person. Consequently such a person has to be available but for the moment there is no such massive phenomenon on a national scale. In terms of social and economic bases of social development the necessity of administration is determined by division of labor on the one hand and by the need for its cooperation on the other. The modern new paradigm of public administration is more likely based on the idea of more and more complete inclusion of a creative person into the structure of the subject of management connected with collective intelligence that transforms the society, as described in this chapter.

Authors: Karadeniz Oğuzhan , Faiz Melike
Published: July 2014

In today's world of the twenty-first century, both technology and social communities which technology develops have gotten a greater change process than those in the past. Social change introduces the concept of chaos to us. Literally, chaos means order in disorder. Individuals have fallen into despair as a result of social changes. Determining the situations of chaos which individuals experience is an important step. This chapter compares chaotic cases of Social Studies teacher candidates who study in Turkey and the United States of America about social phenomena. This research was carried out in two different education institutions including a faculty of education in Turkey and a college in the United States of America. A total of 30 social studies teacher candidates including 15 people in Turkey and 15 people in the United States of America were participated into the research. Data obtained were analyzed by the method of content analysis after research conducted.
A Comparative Analysis of the Human Resource Development Systems of Turkey and Uganda
Authors: Bisaso Ssali Muhammadi
Published: July 2014

In this chapter, the Human Resource Development systems of Turkey and Uganda are examined. A document survey and library search technique were used to explore the status-quo regarding Human Resource Development processes in the two countries with focus on legal structures as well as structural set ups pertaining the field in question. The major findings in relation to the comparison made indicate that Turkey as a developing country has a much better Human Resource Management and development set up compared to Uganda as a less developed country. This is highlighted by the fact that in Turkey entry into any Human Resource professional field involves a series of examination levels to the effect of KPSS, KPDS, and ALES while in Uganda such entry would only require interviews. Meanwhile, Turkey's human resource development program features a streamlined policy on foreign based Human Resources while Uganda, though it has some effort in place, is still far from the required standard in this respect. One glaring similarity though is that in both countries the Human Resource Development unit depends on other units in the ministry. It is therefore opined that there are a lot of learning points in the Human Resource Development process in Turkey for a less developed country like Uganda.

Neural Control of Muscle
Authors: Bawa Parveen , Jones Kelvin E.
Published: July 2014

The purpose of this chapter is to introduce the reader to the development of ideas and concepts about the manner in which the central nervous system controls muscle contraction. The motor unit, the quantum of muscle contraction, is fundamental to concepts of the neural control of muscle and will be the focus of discussion. The population of motor units comprising a skeletal muscle have a diverse range of physiological and anatomical properties. The Size Principle of motor unit recruitment is a concept that proposes a simple strategy for exploiting the diversity of the motor unit population to produce graded force output. The Size Principle has a great deal of empirical support, but also faces criticism about the extent of generalization to all types and forms of movement. As the key principles of motor units are discussed, methods of measuring and methodology for analysing motor unit activity and whole muscle activities are introduced.
Arm Swing during Human Gait Studied by EMG of Upper Limb Muscles
Authors: Kuhtz-Buschbeck Johann P. , Frendel Antonia , Jing Bo
Published: July 2014

Arm swing during human gait has both passive and active components. The chapter presents a study conducted with normal subjects using electromyography (EMG) to describe patterns of arm and shoulder muscle activity in different gait conditions. These included normal forward walking, walking with immobilized arms, backward walking, power walking with accentuated arm swing, running, and load carriage. Complementary kinematic data are presented, too. Rhythmic muscle activity persists to some extent when both arms are immobilized during walking. Forward and backward walking involve dissimilar patterns of muscle activity, although the limb movements are very similar in both conditions. Likewise, power walking and running are characterized by different curves of EMG activity. Unimanual load carriage during walking affects muscle activities of both the loaded and the non-loaded arm. Research on normal arm swing provides a basis for clinical investigations of gait disorders.
Using in Vivo Subject-Specific Musculotendon Parameters to Investigate Voluntary Movement Changes after Stroke
Authors: Hu Hujing , Li Le
Published: July 2014

Neuromusculoskeletal modeling provides insights into the muscular system which are not always obtained through experiment or observation alone. One of the major challenges in neuromusculoskeletal modeling is to accurately estimate the musculotendon parameters on a subject-specific basis. The latest medical imaging techniques such as ultrasound for the estimation of musculotendon parameters would provide an alternative method to obtain the muscle architecture parameters noninvasively. In this chapter, the feasibility of using ultrasonography to measure the musculotendon parameters of elbow muscles is validated. These parameters help to build a subject-specific EMG-driven model, which could predict the individual muscle force and elbow voluntary movement trajectory using the input of EMG signal without any trajectory fitting procedure involved. The results demonstrate the feasibility of using EMG-driven neuromusculoskeletal modeling with ultrasound-measured data for prediction of voluntary elbow movement for both unimpaired subjects and persons after stroke.
Study and Interpretation of Neuromuscular Patterns in Golf
Authors: Marta Sérgio , Vaz João Rocha , Silva Luís , Castro Maria António , Correia Pedro Pezarat
Published: July 2014

This chapter reports the golf swing EMG studies using amplitude, timing parameters and approaches to neuromuscular patterns recognition through EMG. The golf swing is a dynamic multi-joint movement. During each swing phase different activation levels occur, the combination of each muscle in amplitude provides an increased club head speed for the ball to travel to the hole. The timing when the maximum peak of each muscle occurs can be an important factor to understand the injury related mechanics and to prescribe strength programs. Most muscle studies describe their maximum activation level during the forward swing and acceleration phases, providing a controlled antigravity movement and acceleration of the club. The initial contraction time corresponds to the onset that can be used to describe the organization of the neuromuscular patterns during a task. This time parameter was used in golf to relate injuries to skilled or less skilled golfers. The way to retrieve this time parameter may be reached through new approaches but no gold standard algorithm definition has been found yet. To better understand the neuromuscular patterns new algorithms based on the dynamical systems theory are now used.
Endurance Time Prediction using Electromyography
Authors: Boyas Sébastien , Guével Arnaud
Published: July 2014

The purpose of endurance time (Tlim) prediction is to determine the exertion time of a fatiguing muscle contraction before it occurs. Tlim prediction would then allow the evaluation of muscle capacities while limiting fatigue and deleterious effects associated with exhaustive exercises. Fatigue is a progressive phenomenon which manifestations can be observed since the beginning of the exercise using electromyography (EMG). Studies have reported significant relationships between Tlim and changes in EMG signal suggesting that Tlim could be predicted from early EMG changes recorded during the first half of the fatiguing contraction. However some methodological factors can influence the reliability of the relationships between Tlim and EMG changes. The aim of this chapter is to present the methodology used to predict Tlim from early changes in EMG signal and the factors that may influence its feasibility and reliability. It will also present the possible uses and benefits of the Tlim prediction.
EMG Activation Pattern during Voluntary Bending and Donning Safety Shoes
Authors: Nag P. K. , Chorsiya Varsha , Nag Anjali
Published: July 2014

Posture control is a well-coordinated interplay of sensory-motor system and forms the basis of voluntary movements. The daily activities and occupational task involves voluntary bending in different directions, which if falls beyond the limit of stability can cause slipping, tripping and falling. Further, these accidents are very common in industries where workers have to wear safety shoes to protect their feet from hazards of the work environment. The study elucidates the muscular activation patterns in light of electromyographic (EMG) findings for voluntary bending within limits of stability and with donning of safety shoes. The aim of this chapter is to potentially contribute to occupational health and safety at workplaces. The present findings have implications regarding the viability of muscle adaptability as a putative postural control in preventing postural instability and avoiding injuries.
Tongue Movement Estimation Based on Suprahyoid Muscle Activity
Authors: Sasaki Makoto
Published: July 2014

The motor function of the tongue often remains intact even in cases of severe movement paralysis. Therefore, tongue movements offer great potential for the design of highly efficient human-machine interfaces for alternative communication and control. This chapter introduces a novel method for tongue movement estimation based on analysis of surface electromyography (EMG) signals from the suprahyoid muscles, which usually function to open the mouth and to control the hyoid position.
Design of Myocontrolled Neuroprosthesis
Authors: Ambrosini Emilia , Ferrante Simona , Pedrocchi Alessandro
Published: July 2014

Recent studies suggest that the therapeutic effects of Functional Electrical Stimulation (FES) are maximized when the patterned electrical stimulation is delivered in close synchrony with the attempted voluntary movement. FES systems that modulate stimulation parameters based on the residual volitional muscle activity would assure this combination. However, the development of such a system might be not trivial, both from a hardware and a software point of view. This chapter provides an extensive overview of devices and filtering solutions proposed in the literature to estimate the residual volitional EMG signal in the presence of electrical stimulation. Different control strategies to modulate FES parameters as well as the results of the first studies involving neurological patients are also presented. This chapter provides some guidelines to help people who want to design innovative myocontrolled neuroprostheses and might favor the spread of these solutions in clinical environments.

Published: July 2014

This chapter employed an interdisciplinary attempt to investigate agricultural climate information use, linking sociology of translation (actor-network theory) and actor analysis premises in a qualitative research design. The research method used case study approaches and purposively selected a sample consisting of wheat growers of the Fars province of Iran, who are known as contact farmers. Concepts from Actor-Network Theory (ANT) have been found to provide a useful perspective on the description and analysis of the cases. The data were analyzed using a combination of an Actor-Network Theory (ANT) framework and the Dynamic Actor-Network Analysis (DANA) model. The findings revealed socio political (farmers' awareness, motivation, and trust) and information processing factors (accuracy of information, access to information, and correspondence of information to farmers' condition) as the key elements in facilitating climate information use in farming practices.

Authors: Wickramasinghe Nilmini , Tatnall Arthur , Goldberg Steve
Published: July 2014

The WHO has labelled diabetes the silent epidemic. This is because the instances of diabetes worldwide continue to grow exponentially. In fact, by 2030 it is expected that there will be a 54% global increase. Thus, it behooves all to focus on solutions that can result in superior management of this disease. Hence, this chapter presents findings from a longitudinal exploratory case study that examined the application of a pervasive technology solution, a mobile phone to provide superior diabetes self-care. Notably, the benefits of a pervasive technology solution for supporting superior self-care in the context of chronic disease are made especially apparent when viewed through the rich lens of Actor-Network Theory (ANT), and thus, the chapter underscores the importance of using ANT in such contexts to facilitate a deeper understanding of all potential advantages.
Human Interactions in Software Deployment
Authors: Sekgweleo Tefo , Iyamu Tiko
Published: July 2014

Software is intended to enable and support organisations, in order for them to function effectively and efficiently, towards achieving their strategic objectives. Hence, its deployment is critically vital to the focal actors (managers and sponsors). Software deployment involves two primary components, technology and non-technology actors. Both actors offer vital contributions to software deployment from different perspectives. Unfortunately, there has been more focus on the technological actors over the years. This could be attributed to why the same types of challenges, such as disjoint between development and implementation, persist. This chapter holistically examines the roles of non-technology actors in the deployment of software in organisations. The Actor-Network Theory (ANT) provides a lens in the analysis of the empirical data.
Studying DNA
Authors: Quinlan Andrea
Published: July 2014

Feminist methodologies and Actor-Network Theory (ANT) have often been considered opposing theoretical and intellectual traditions. This chapter imagines a conversation between these seemingly divergent fields and considers the theoretical and methodological challenges that ANT and particular branches of feminist thought raise for the other. This chapter examines an empirical project that calls for an engagement with both ANT and feminist methodologies. Through the lens of this empirical project, four methodological questions are considered, which an alliance between ANT and feminist methodologies would raise for any research project: 1) Where do we start our analysis? 2) Which actors should we follow? 3) What can we see when we begin to follow the actors? 4) What about politics? The potential places where ANT and feminist methodologies can meet and mutually shape research on scientific practice and technological innovation are explored. In doing so, this chapter moves towards envisioning new intersections between feminist methodologies and ANT.
Disturbing Practices in Engineering Design Projects
Authors: Gonçalves Fernando Abreu , Figueiredo José
Published: July 2014

Most references to innovation relate to the development of new products. In this chapter, the authors do not address innovation in these terms; instead, they address them as changes in practices an engineer creatively adopts during engineering design projects. They adopt Actor-Network Theory as a way to understand these change processes (translations). The authors design a perturbation index inspired in Earned Value management to measure translation effort, having in mind the management of scope. Then they assess changes of regime in resource allocation of tasks and conclude some changes can lead to innovative results. That means we gain a wider view about scope, and scope management, being able to observe and change good practices, something crucial in engineering design projects where requirements and goals drift.
Web Tools as Actors
Authors: Adamopoulos Arthur , Dick Martin , Davey Bill
Published: July 2014

Often actor-network theory studies find that technology has been translated through its relationships with human actors. This chapter reports on a study of online investing that found that the human actors were translated to more active and involved investors due to the changes, over time, in the online services that are available: the non-human actors. The Internet is a constantly evolving technological actor. New tools have the potential to change interactions with users. In this study, it became evident that new services had a noticeable effect on the behaviour of investors. Not only did investors report changes in their behaviour when they moved from offline to online investing, but they also reported changes in their investing strategies over time as new services became available. This study showed a new and interesting confirmation of the value of allowing non-human actors to be heard.

Authors: Huang Hao Yong , Cheng Yuan Fang , Zhao Wei , Cheng Chong , Deng Wen Biao
Published: July 2014

Based on the size effect of rock strength, the borehole stability analysis model is established, which the borehole size is taken into consideration. Through this model, the relation between borehole size and collapse pressure under borehole pressure, ground stress and drilling fluid flow function is analyzed. The analysis shows that with the increase of borehole diameter, collapse pressure increases significantly, and borehole stability becomes poor, but the variation of borehole size is not proportional to collapse pressure: the bigger the borehole, the smaller the variation. When borehole diameter increases from 152.4 mm to 444.5 mm, wellbore collapse pressure increases from 1.18g/cm3 to 1.315g/cm3 and the rate of the increase is 11.44%. When slimhole drilling technology is applied, the density of minimum fluid that maintains wellbore stability is lower than the one used in conventional wellbore drilling.

Seven-bar seedling planting mechanism is one kind of developed transplanting mechanism of vegetable seedling transplanting machines. Dynamic equations of the link rods were established and analysis program was compiled so as to analyze the dynamic characteristics of the mechanism; Meanwhile, simulation model of the mechanism was established and corresponding virtual dynamic test was conducted based on Adams. The consistency between calculation results based on kinematic theory model and simulation results achieved from Adams was proved through comparison, which verified the dynamics model was correct and reliable. It can be concluded that the dynamic model was the basis of dynamic parameter optimization model of seven-bar seedling planting mechanism, which facilitates the parameter optimization process of the kind of seedling planting mechanism with various specifications, and it also avoided the tedious process of repeated modeling based on Adams dynamics optimization. With the analysis results of the seven-bar seedlings planting mechanism based on the established kinematic model, it was found out that the force fluctuation at the chassis caused by the reciprocating motion of the mechanism was large, which could cause machine vibration and increase the labor intensity of operators.

It is imperative to improve the reliability index of the power transmission line crossing the high-speed railway for the purpose of guaranteeing safe and reliable operation of high-speed railway. Compared with the replacement of all iron towers, the strengthening and reinforcement of original iron towers are an economical and reasonable treatment method. Via the analysis of strengthening methods of iron towers, after different reinforcement measures are taken for different member parts and material forms, the bearing capacity of iron towers may be effectively improved to some extent so as to promote the reliability index of power transmission lines. The strengthening optimization scheme raised on this basis provides references for the strengthening and reinforcement of tower models of the same kind.

Published: July 2014

In this paper, the oil-based magnetic fluid was prepared by chemical co-precipitation method and sodium oleate was the surfactant. The effect of different pH on the characterization of magnetic fluid was studied. The characterization was detected by Fourier Transform Infrared spectroscopy (FT-IR), Transmission Electron Microscope (TEM) and Vibrating Sample Magnetometer (VSM). The results show that the nanoparticles were coated successfully by sodium oleate at pH=5. And the saturation magnetization of Fe3O4 magnetic nanoparticles is 58.0 emu/g, the saturation magnetization of magnetic fluid prepared is 20.2 emu/g, and the Fe3O4 particles are dispersed well. Although the Fe3O4 magnetic particles coated by sodium oleate at pH = 10.5 has a higher saturation magnetization (67.8 emu/g), but the magnetic fluid is less stable and has an obvious settlement phenomenon.

The Ablation Mechanism of Magnetic Driven Flyer Plate
Authors: Wang Gang Hua , Kan Ming Xian , Niu Yi Fei , Zhao Hai Long
Published: July 2014

It is found that the samples usually melt and even gasify in the magnetic driven high-speed flying plate experiments, which phenomenon goes against the investigation on materials’ equation of state (EOS). To understand this phenomenon, the whole process of magnetic driven flying plate experiment is simulated by the magnetohydrodynamic code MDSC. The ablation mechanism of magnetic driven flying plate is analyzed through the control of thermal conduction coefficient, and resistivity coefficient which is related to the magnetic diffusion velocity, in the energy conversing equation. Inside the flying plate the velocity of stress wave is much higher than that of magnetic diffusion, and hence the current goes into the inside of sample no early than the stress wave, so the magnetic diffusion doesn’t play an important role in the first stage of flyer free surface velocity history. The thermal conduction doesn’t influence the whole free surface velocity history of the flying plate much, while the Ohmic heating has a big effect on it, without which more than 20% error will be produced. The energy transportation in the flying plate medium is mainly caused by the Ohmic heating from magnetic diffusion. Besides, the relationship between the magnetic diffusion and temperature of flying plate is also analyzed.

Published: July 2014

In order to get the situation of transitional flow in tube, we tested the fluid field by PIV experiment and acquired the velocity distribution of the flow field at different Reynolds number (Re=2400 and Re=3000). At the same time the structure and characteristics of the flow field were obtained. The experimental result shows that the change of axial velocity in boundary layer is not obvious at low Reynolds number, the fluctuation of axial velocity appears and normal speed changes a little in mainstream area. With the increase of Reynolds number the axial velocity both in boundary layer and mainstream area change obviously, pulsation of the normal speed increases, the state of fluid flow gradually evolves from laminar to transitional flow.

Authors: Choi Jek Wang , Shi Lei Lei , Wu Li Jun , Kim Hyeon Woo , Choi Iksu , Kim Hun Mo
Published: July 2014

The Smart Hybrid Powerpack (SHP) is an electro-hydraulic system which combines the system of Electro Hydraulic Actuator (EHA) and advanced technologies such as network fault tolerance and intelligent control. EHA system has been famous in the industry because that the EHA acts as a power-shift which shifts the power from high-speed electric motor to the high-force of hydraulic cylinder by bi-directional piston pump. If errors in the plant and network occur in the SHP, the system will cause serious malfunctions. To reduce plant noises and network errors, this paper shows the intelligent control method comparing Self-tuning fuzzy with fuzzy control and network fault tolerant error control coding in the SHP. In the intelligent control part, the simulation result shows good performance to reduce plant noises by the self-tuning fuzzy than fuzzy control. In the network fault tolerant error control coding part, proposed scheme also shows good performance by CRC code and Reed-Solomon (R-S) code in two channel (CRT) method than one channel only. We developed LabVIEW Graphic User Interface (GUI) to show these simulation results. Using this GUI, we can save time to experiment and get benefit of guidance to make real program.

In order to significantly improve damage ability on large area targets, it is necessary to resolve the problem of firing distribution for naval gun firing on shore. In the first place, the firing error of naval gun is analyzed. Then the calculation model of damage probability is put forward. Finally, by using damage probability as object function, the model of firing distribution based on optimization method is set up. Simulation result shows that when ammunition consumption is the same, the damage probability of naval gun may be improved remarkably by optimal firing distribution. The model provides scientific evidence for commander to make decision during firing on shore.

This paper proposes a new approach is referred to as condensed nearest neighbor decision rule (CNN) input weight sequential feed-forward neural networks (CIW-SFFNS). In this paper, it is firstly shown that the difference of optimization constraints between the extreme learning machine (ELM) and constrained-optimization-based extreme learning machine. For the second time, this paper proposes a method that using CNN to select the hidden-layer weights from example. Moreover, we compare error minimized extreme learning machines (EM-ELM), support vector sequential feed-forward neural networks (SV-SFFNS) and CIW-SFFNS from two aspects:test accuracy and the number of hidden nodes. We present the result of an experimental study on 10 classification sets. The CIW-SFFNS algorithm has a statistically significant improvement in generalization performance than EM-ELM and SV-SFFNS.

Authors: Sevvel P. , Jaiganesh V.
Published: July 2014

In this paper, the effects of axial force on the mechanical properties of AZ31B magnesium alloy flat plates during the Friction Stir Welding (FSW) process were investigated by carrying out the tensile tests as per the American Society for Testing and Materials (ASTM) E8M-11 standards. The tensile test results indicated that the increase of the axial force greatly improved the tensile shear load (TSL) of the friction stir welded joints at a constant tool rotational speed of 800 rpm and welding speed of 50mm/min. Sound lap joints with low distortion, lack of cavity and high tensile strength were successfully obtained with an axial force of 5kN. However, the TSL of the friction stir welded joints decreased when the axial forces were 3kN and 4kN with the same constant tool rotational and welding speed.

Published: July 2014

Scheduling is the allocation of resources over time to carry out a collection of tasks assigned in any field of engineering and non engineering. Majority of JSSP are categorized into non deterministic (NP) hard problem because of its complexity. Scheduling are generally solved by using heuristics to obtain optimal or near optimal solutions because problems found in practical applications cannot be solved to optimality using available resources in many cases. Many researchers attempted to solve the problem by applying various optimization techniques. While using traditional methods they observed huge difficulty in solving high complex problems and meta-heuristic algorithms were proved most efficient algorithms to solve various JSSP so far. The objective of this paper i) to make use of a newly developed meta heuristic called Firefly algorithm (FA) because of inspiration on Firefly and its characteristic. ii) To find the combined objective function by determining optimal make span, mean flow time and tardiness of different size problems (using Lawrence 1-40 problems) as a bench marking dataset and to find the actual computational time. Iii) to prove that the proposed FFA algorithm is a good problem solving technique for JSSP with multi criteria.

Published: July 2014

The n-job, m-machine Job shop scheduling (JSP) problem is one of the general production scheduling problems in manufacturing system. Scheduling problems vary widely according to specific production tasks but most are NP-hard problems. Scheduling problems are usually solved using heuristics to get optimal or near optimal solutions because problems found in practical applications cannot be solved to optimality using reasonable resources in many cases. In this paper, optimization of three practical performance measures mean job flow time, mean job tardiness and makespan are considered. New Game theory based heuristic method (GT) is used for finding optimal makespan, mean flow time, mean tardiness values of different size problems. The results show that the GT Heuristic is an efficient and effective method that gives better results than Genetic Algorithm (GA). The proposed GT Heuristic is a good problem-solving technique for job shop scheduling problem with multi criteria.
