Abstract
There is an evident lack of studies examining the factors associated with reactive agility performances. The aim of this study was to evaluate the association between anthropometrics, body composition, jumping capacity, reactive strength, and balance with a stop-and-go change of direction speed (CODS) and reactive agility. The total sample comprised 39 male (body height: 182.95 ± 5.19 cm; body mass: 80.66 ± 7.69 kg) and 34 female (body height: 171.45 ± 6.81 cm; body mass: 61.95 ± 6.70 kg) college-level athletes (21.9 ± 1.9 years of age). The variables included body height, body mass, the percentage of body fat (BF%), balance as measured by an overall-stability index, the countermovement jump (CMJ), a reactive-strength index (RSI), stop-and-go reactive agility, and stop-and-go CODS. To define the associations between motor and anthropometric variables with CODS and reactive agility, the participants were clustered into three achievement groups based on their CODS and reactive agility performances. The ANOVA showed a significant difference between the CODS-based achievement groups for the CMJ (F test = 3.45 and 3.60 for males and females, respectively; p < 0.05), the RSI (F test = 6.94 and 5.29 for males and females, respectively; p < 0.05), and balance (F test = 3.47; p < 0.05 for males). In females, the reactive agility achievement groups differed significantly in the RSI (F test = 6.46; p < 0.05), the CMJ (F test = 4.35; p < 0.05) and BF% (F test = 4.07; p < 0.05), which is further confirmed by discriminant canonical analysis (Can R = 0.74; p < 0.05). The results confirm the need for independent evaluation and training for both CODS and reactive agility performance in sports.

Abstract
Change is pervasive, but emerging patterns are occasionally detectable through analysis of systemic behaviors. Match analysis uses these patterns in order to reduce the degree of improvisation and to optimize the training process. However, it is possible that certain game phases elude systematic patterning. In this vein, our aim was to analyze the case of attack coverage in men’s volleyball, as we suspected it would elude systematic patterning and has received negligible attention in scientific research. We analyzed the occurrence of attack coverage in 4544 plays of the 2011 Volleyball World League. A Chi-square test with residual adjusted values was applied to explore significant associations between variables. A Monte Carlo correction was applied, as some cells had n<5. Effect sizes were determined using Cramer’s V. Overall, attack coverage occurred in 3.89% of ball possessions, and 23 distinct structures emerged. These structures lacked significant associations with the game complex, setting zone, and effect of attack coverage. Conversely, attack coverage structures showed significant associations with the attack zone and tempo, with very strong effect sizes (V=0.472 and V=0.521, respectively). As certain attack zones are deeply associated with attack tempo, it is apparent that quicker attack plays affect attack coverage structuring, promoting the formation of less complex structures. Ultimately, attack coverage structures seem to depend on momentary constraints, thereby rendering rigid systematization impracticable. Still, we contended that a principle-based approach might be suitable. This invites researchers to rethink how to interpret game regularities.

Abstract
Cognitive performance includes the processes of attention, memory, processing speed, and executive functioning, which typically declines with aging. Previous research has demonstrated that aerobic and resistance exercise improves cognitive performance immediately following exercise. However, there is limited research examining the effect that a cognitively complex exercise such as martial art training has on these cognitive processes. Our study compared the acute effects of 2 types of martial art training to aerobic exercise on cognitive performance in middle-aged adults. We utilized a repeated measures design with the order of the 3 exercise conditions randomly assigned and counterbalanced. Ten recreational middle-aged martial artists (mean age = 53.5 ± 8.6 years) participated in 3 treatment conditions: a typical martial art class, an atypical martial art class, and a one-hour walk at a self-selected speed. Cognitive performance was assessed by the Stroop Color and Word test. While all 3 exercise conditions improved attention and processing speed, only the 2 martial art conditions improved the highest order of cognitive performance, executive function. The effect of the 2 martial art conditions on executive function was not different. The improvement in executive function may be due to the increased cortical demand required by the more complex, coordinated motor tasks of martial art exercise compared to the more repetitive actions of walking.
A Practical Approach to Operational Hydrodynamic Slug Analysis in Pipelines
Authors: Galatro Daniela , Ercolani Dario , Fuertbauer Daniel 
Published: February 2016

Abstract
Hydrodynamic slugs in pipelines are usually analysed by using steady-state flow simulation software as a first approximation and then modelled in transient simulation software in order to get more accurate values. In this work, the ILF approach for hydrodynamic analysis is presented by using an empirical and a mechanistic method for steady-state simulations and by using a transient approach. For both, steady-state and transient simulations commercial software is applied. Furthermore, a new pseudo-transient approach as an alternative to the Lagrangian slug tracking scheme that is currently tested is presented. A set of operational hydrodynamic slug examples illustrates the use and accuracy of both commercial simulation programs and the newly developed pseudo-transient approach. Finally, a set of considerations for the hydrodynamic slug analysis in pipelines is proposed as a guide for accurate estimation of the slug properties.
Enhancement of MSF Using Microbubbles

Published: February 2016

Abstract
Multi Stage Flash (MSF) distillation plants are widely used in saline water desalination. In order to enhance MSF, it is important to increase an evaporation rate in the flashing stage. A spray flash method, in which superheated water jets are injected through nozzles into a depressurized environment to increase the gas/liquid interface area, is a promising technique to make the increase of evaporation rate, which leads directly to the reduction of energy consumption and cost of the MSF plant. In this paper, the introduction of microbubbles into the spray jet as the nucleation sites to increase the evaporation rate of the spray flash is proposed. The spray flash behaviours with/without microbubbles at outside/inside of the nozzle-inside were observed by means of a high speed camera to investigate the mechanism of enhancement of spray flash due to microbubbles. Moreover, the number densities of droplets and bubble volume increase were obtained from visualized images in order to discuss quantitatively on the effects of introduction of microbubbles.

Abstract
The silicon tracker of the ATLAS experiment at CERN Large Hadron Collider will operate around –15°C to minimize the effects of radiation damage. The present cooling system is based on a conventional evaporative circuit, removing around 60 kW of heat dissipated by the silicon sensors and their local electronics. The compressors in the present circuit have proved less reliable than originally hoped, and will be replaced with a thermosiphon. The working principle of the thermosiphon uses gravity to circulate the coolant without any mechanical components (compressors or pumps) in the primary coolant circuit. The fluorocarbon coolant will be condensed at a temperature and pressure lower than those in the on-detector evaporators, but at a higher altitude, taking advantage of the 92 m height difference between the underground experiment and the services located on the surface. An extensive campaign of tests, detailed in this paper, was performed using two small-scale thermosiphon systems. These tests confirmed the design specifications of the full-scale plant and demonstrated operation over the temperature range required for ATLAS. During the testing phase the system has demonstrated unattended long-term stable running over a period of several weeks. The commissioning of the full scale thermosiphon is ongoing, with full operation planned for late 2015.

Published: February 2016

Abstract
The in-situ generation of hydrogen peroxide in the electro-Fenton process is paramount. For this reason, in this research the electrocatalytic activity of three carbon materials was evaluated in the reaction of oxygen reduction via two electrons. Furthermore, in order to eliminate the use of iron salts in solution (homogeneous process), the iron was electrodeposited on the surface of the carbon material and was applied in a heterogeneous electro-Fenton process for the degradation of methyl orange dye. The largest amount of generated H2O2 was achieved with the Carbon Felt (CF) electrode (460 mg L−1) without iron after 60 minutes. The electrodes with electrodeposited iron were characterized by SEM and EDS, which showed that the surface of the Carbon Sponge (CS) electrode had the largest amount of iron (23.84 %). However, the CF electrode showed a greater and faster degradation of the dye (98 %) after 30 minutes of treatment. The CF material was the best and most-viable choice of material compared to the CS and Carbon Cloth (CC) for industrial application in electro-Fenton processes, due to its greater catalytic activity in the production of H2O2, uniform distribution of iron, more efficient TOC removal and lower cost per cm2 of material.
Low-carbon Building Innovation Trends and Policy Pespectives in Hungary between 2020 and 2030
Authors: Fogarassy Csaba , Horvath Balint 
Published: February 2016

Abstract
Regarding the aspects of climate policy, the building sector in Hungary is one of the best performing industries. This means that the GHGs (Greenhouse Gasses) the sector emits can be decreased more effectively and at less cost than in the case of other sectors. This is no surprise in the European Union, since there is a continual demand on behalf of society to develop old and outdated buildings, thus modern technological solutions also inherently result in operating efficacy. The ‘climate policy targeted’ development of the built environment based on EU funds is thus one of the most popular developments amongst European Union Member States. Therefore, the aim of the present study is to assess the climate policy effects of the presently preferred strategy approach(es) between 2020 and 2030.

Rational and Relational Bases of Public Managers’ New Profiles in the Context of Trust Research
Authors: Kożuch Barbara , Sienkiewicz-Małyjurek Katarzyna , Luty Lidia 
Published: February 2016

Abstract
Competencies are a set of distinctive resources and opportunities. They relate to specific capabilities of management and to performance of management methods. In the catalogue of existing managerial competencies, an increasingly important role is played by trust. The deep insight in this field of literature gives grounds for the inference that trust is rather a means to achieve public organisations’ goals, than being the end in itself. Therefore in this article we have assumed, that contemporary competencies, to a large degree, rely on trust which is rationally and relationally rooted.
The main aim of this paper is to identify and evaluate components of trust with reference to the competences of public managers mirrored in their new profiles. To achieve the goal of the article, publications of the field of organisational studies and public management which aim to show the importance of creating trust within an organisation were reviewed to identify main managerial competences analysed in the context of public trust as an important factor of improving public organisations. Moreover, the results of a survey with 93 respondents carried out in 2014 in 8 units of local public administration from the Malopolska Region were used. As a result the main components of trust in new public managers’ profiles have been identified and assessed.

Authors: Sanjeewani Dasanayaka Rasika , Kuruppuge Ravindra Hewa 
Published: February 2016

Abstract
Information Technology (IT) industry in Sri Lanka can be considered as one of the fast growing industrial sectors in current competitive, technological oriented and rapidly changing business environment. Generally, IT industry performance depends on knowledge management (KM) in firms in the industry. The concept of staff turnover (ST) has become as more important aspect in the context of knowledge management. As limited research studies are shown in literature about staff turnover and knowledge management in IT industry in Sri Lanka, this research explore the impact of staff turnover on knowledge management in IT companies in Sri Lanka. The survey method has been adopted using structured questionnaire in Likert scale to collect data. Respondents from different job categories and companies for the sample have been selected using stratified sampling method. After descriptive analysis of basic features of respondents of the survey, the causal relationship between staff turnover and knowledge management is analyzed using correlation analysis. The major finding emulating from the study is that there is a positive relationship between high staff turnover and weak knowledge management. Further, the study shows that organizational factors such as managerial style, lack of recognition, lack of competitive compensation system and toxic workplace environment significantly influence employee knowledge management. However, possible learning environment in the firm also directs employee turnover in IT industry in Sri Lanka.

Abstract
The important feature of effective manager is to understand emotions in an effective method. This study looks into cultural variations in trait Emotional Intelligence among the business managers from the provinces of Pakistan i.e. Sindh, Punjab, Khyber Pakhtunkhwa and Balochistan. Comparing rotated component matrixes of these four provinces revealed the four traits emotional intelligence factors, Well-being, Self-control, Emotionality, and Sociability of these provinces. Short-form of Trait emotional intelligence Questionnaire developed by Petrides [2009] has employed to measure the 404 business managers from four provinces in present article. The results revealed evident the cultural differences in trait emotional intelligence scores with the business managers of Sindh scoring consistently higher than other three provinces and the business managers from Balochistan province scores are at lowest. These cross cultural differences may have ramification for global EI trait, well-being, self-control, emotionality and sociability in business manager’s performance, negotiation, conflict management, decision making and organizational development.
Intercultural Project Management for IT: Issues and Challenges
Authors: Isern Germinal 
Published: February 2016

Abstract
The development of Information Technology projects using Project Management Methodologies like PMP-PMI, Agile or SCRUM for software development, CPM, CCPM, RAD, XP, FDD, ITIL, JAD, LD, PRINCE2, etc.; may be a complete success or a total catastrophe, for series of reasons, events and circumstances that frequently are not related at all with the deliverables, the products being built, the IT technology involved, the level of expertise, the responsibility and professionalism of the stakeholders including the project manager, but due to intercultural factors. The PMP-PMI Model (PMBOK) describes 10 areas: Cost Management, Time Management, Scope Management, Risk Management, Quality Management, Procurement Management, Integration Management, Stakeholder Management, Human Resources Management and Communication Management. An IT project is considered successful if the customer is happy, but technically and formally if the TEAM was able to meet the triple constraint set up by time/cost/scope. This happy ending is not possible if the project manager and the team as a whole are not able to confront, attack and solve the issues associated with Human Resources Management, Stakeholder Management and specially Communication Management.
These three areas are highly influenced by Intercultural factors like language, race, age, gender, religion, sexual preferences, beliefs, habits, etc., becoming their analysis an essential task if we want to accomplish and guarantee a favorable outcome. This position paper concludes in contradiction with what is a very common believe between many technical project managers that the most important factors to take in consideration for the success of an IT project management is the careful and planned attention to the potential issues and challenges associated with the cross-cultural communication and the human resources implicated in the projects. This paper will describe the cultural dimensions, issues and challenges associated with Intercultural Project Management for IT.
Family Involvement in the Firm and Exports in the Family SME: Is the Manager’s International Orientation Influential?
Authors: Basly Sami 
Published: February 2016

Abstract
Does the family involvement affect exports in the family firm? The literature seems to support this view even if the direction and magnitude of this impact remains controversial. Drawing on the perspectives of agency [Chrisman et al. 2004; Schulze et al. 2001] and stewardship as applied to family firms [Davis, Schoorman and Donaldson 1997] and also on socio-emotional wealth perspective [Gómez-Mejía et al. 2007], this study seeks to contribute to this debate by studying the influence of family involvement on the SME exports intensity. To reconcile the divergent views, our research attempts to assess the role of the manager’s international orientation as a variable moderating the relationship between family involvement and exports in SMEs. Based on a hypothetical-deductive approach, the study uses a sample data of 125 family SMEs obtained through a questionnaire. The results show that even if the positive influence of the manager’s international orientation is corroborated, its moderating role seems to be limited to only one facet of the construct of family involvement i.e. involvement in management. Moreover, owning-family involvement in management seems to negatively influence exports while some results argue for a positive effect of the family involvement in ownership on exports.
Articulatory correlates of metrical structure: Studying jaw displacement patterns
Authors: Erickson Donna , Kawahara Shigeto 
Published: February 2016

AbstractPrevious phonetic studies of metrical prominence have primarily focused on its acoustic manifestations, including pitch, intensity, duration, spectral tilt, etc. In this paper we outline our new research program in which we explore jaw displacement patterns as another articulatory reflex of metrical prominence. We present our studies of English and Japanese in some detail, which show that jaw movement patterns are neither flat nor random, but instead the degrees of jaw displacement correlate well with metrical prominence. Based on these results, we argue that there are at least two articulators to express metrical prominence: the larynx and the jaw. Our aim is not so much to object to looking at the acoustic manifestations of metrical structures or other articulation-based approaches; we instead would like to encourage other researchers to investigate metrical structure in terms of jaw movement as well.
Differences in Power Distribution and Health Risk for the Tool Operator Predicted by Human Physical Models in the ISO 10068:2012 Standard
Authors: Dobry Marian W. , Hermann Tomasz 
Published: February 2016

Abstract
The article presents an approach to assessing human physical models specified in the ISO 10068:2012 standard. The models were compared on the basis of energy analysis, which was conducted in terms of power distribution. Since the models in question have a fully specified internal structure, the investigation focused on power distribution in the models and the total power in the system. The article provides a description of the construction and energy-based modelling of Human-Tool systems. Simulation results obtained during the study were analysed in terms of health risks posed to the tool operator.
