The Effectiveness of Speaking Instruction through Task-Based Language Teaching

Speaking is a crucial part of second language learning and teaching. Teaching speaking is not merely to let students to repeat or memorize dialogues, but they should be able to use the utterance to communicate in the real situations. Teachers’ attitudes to respond the students thought and opinion is important, as they should not be forced to speak and put them in the deep anxiety , but we invite the learners to use any languages in the performance of oral tasks where teachers give a task and learners complete the task. Teachers should be able to create such situations where students hold meaningful tasks that will promote their speaking proficiency. This can be realized when students works with their friends in groups to complete a task. Task-Based approach is the alternate to solve the problem where learning is developed through performing a series of activities as steps towards successful task realization.
Towards a prototype development for construction material procurement using SharePoint

One of the main problematical operational issues in construction projects is the co-ordination of building materials to arrive on site at the right time, in the right quantities, and at an acceptable quality level. The number and details of the steps involved in the material lifecycle indicate the complex nature of the process and the potential for problems in the process for even a relatively small project. This heightens the need for more flexible and sophisticated project management tools to support collaborative geographically dispersed participants in the simultaneous planning and scheduling of tasks, and their execution, and they must highlight the critical technical and business risks that challenge successful material procurement. This work illustrates the use of a SharePoint environment to tackle problems in the interesting field of material supply chain, from the point of view that collaborative working is necessary in the materials supply chain environment. Hence, it justifies the use of techniques such as Just-In-Time decision support for material procurement processes. This paper is based on a case study which describes and discusses current and future approaches to material procurement, which can enhance the project team’s activities. Ultimately, improvements in material procurement as a result of effective and efficient communication and document management approach can reduce construction times, information overload, and costs.
Resilience by diversity: Large intraspecific differences in climate change responses of an Arctic diatom

The potential for adaptation of phytoplankton to future climate is often extrapolated based on single strain responses of a representative species, ignoring variability within and between species. The aim of this study was to approximate the range of strain‐specific reaction patterns within an Arctic diatom population, which selection can act upon. In a laboratory experiment, we first incubated natural communities from an Arctic fjord under present and future conditions. In a second step, single strains of the diatom Thalassiosira hyalina were isolated from these selection environments and exposed to a matrix of temperature (3°C and 6°C) and pCO2 levels (180 μatm, 370 μatm, 1000 μatm, 1400 μatm) to establish reaction norms for growth, production rates, and elemental quotas. The results revealed interactive effects of temperature and pCO2 as well as wide tolerance ranges. Between strains, however, sensitivities and optima differed greatly. These strain‐specific responses corresponded well with their respective selection environments of the previous community incubation. We therefore hypothesize that intraspecific variability and the selection between coexisting strains may pose an underestimated source of species' plasticity. Thus, adaptation of phytoplankton assemblages may also occur by selection within rather than only between species, and species‐wide inferences from single strain experiments should be treated with caution.
Immunophenotyping of Acute Leukemias – From Biology to Clinical Application

Immunophenotyping is an essential part of the modern diagnostic workup of acute leu‐ kemias and thus for an appropriate treatment of these complex and heterogeneous dis‐ eases. It provides a lot of useful information in this setting that transfers directly from laboratory to clinical management of patients. Lineage definition is the first goal leading to proper initial therapy. Some phenotypic patterns define specific subsets correlating with poor (mixed phenotype, dendritic cell neoplasm) or favorable (cortical T-lympho‐ blastic leukemia) outcome, thus guiding the application of treatment modalities. An ad‐ vanced analysis of phenotypic data can address specific issues, such as the still debated role of multilineage dysplasia. The quality of response to chemotherapy is monitored by the detection of minimal residual disease and peripheral blast clearance during chemo‐ therapy delivering. That allows a sharp discrimination of prognosis and again can drive the intensity of therapies proportionally to the disease chemosensitivity.
Comparison and detail study of attacks and detection methods for wireless sensor network

Wireless sensor network is emanating technology in the field of telecommunications. WSNs can be applied in many fields like machine surveillance, precision agriculture, home automation and intelligent building environments. However the major aspect of WSN is the security as the sensor nodes are limited because of these facing several security threats such as black hole attack, worm hole attack, flooding etc. which is finally affecting the functioning of the whole network. These attacks are maximizing the consumption of power in the node and also it decreases life of the battery. In this paper, we discuss several types of security attacks in wireless sensor networks and also it introduces various intrusion detection systems to detect these attacks and prevent the compromised nodes in the WSN. And also we discuss about the different intrusion detection methods with the help of machine learning algorithms. In future these techniques can be helpful to create a safe and sophisticated network.
Micro and macro indicators of competition: comparison and relation with productivity change

This paper investigates competition in the Dutch manufacturing sector. We look at various indicators that have been used throughout the literature and relate these to productivity growth. Moreover, where possible, the indicators and productivity growth are calculated at both the firm and industry level. This enables us to investigate differences in competition and in its relation with productivity for both aggregation levels. Our results indicate that contemporaneous competition is associated with lower productivity, while lagged competition is positively associated with productivity. This finding is consistent between micro and macro, and robust over the various indicators and industries. The results are consistent with the idea that firms first experience negative effects of changes in competition and need time to adjust, while in the period after adjustment productivity rises again.

Design of a process overview display in a Human-Machine-Interface

The aim of this master thesis is to present new and well proven methods about how to best design an overview display. Since designing is a creative process and there can be many alternative designs that fulfill the same requirements, this master thesis will focus on presenting guidelines and principles that will aid in the design process. How to design an effective interface display will be discussed in the context of Endsley’s Situation Awareness model. This master thesis will cover ideas such as Information Rich display Design (IRD), High Performance Human Machine Interface (HPHMI), as well as briefly discuss alarm system design. The psychological aspect of implementing a change and making it a successful one is discussed in the light of the ADKAR model. This includes creating awareness, desire, knowledge, ability and reinforcement to the change. The two main types of overview displays, functional overview display and schematic overview display, will be compared by bringing forth pros and cons for both types. A practice oriented design process for overview displays is presented. The three main steps of this process are (1) identify the critical variables, (2) identify the critical interactions and (3) identify appropriate visualizations. An overview display will be presented for a chemical process plant that produces Trimethylolpropane (TMP) in Perstorp. This master thesis will include interviews with an operator and a subject matter expert to identify the information needs according to the practice oriented design process. The overview display is presented in the software DeltaV.
Effectively Reconstructing the Routing Paths in Sensor Networks

In wireless sensor networks, sensor nodes are usually self-organized or self sorted, delivering data to a central sink in a multi-hop manner. Reconstructing the per-packet routing path enables fine-grained diagnostic analysis and performance optimizations of the network. The performances of existing path reconstruction approaches like MNT, however, goes down rapidly in large scale networks with loss links or failed links. We present Pathfinder, a vigorous path reconstruction method against packet losses as well as routing dynamics. At the node side, Pathfinder exploits temporal correlation between a set of packet paths and efficiently compresses the path information using path difference. At the sink side, Pathfinder infers packet paths from the compressed information and employs intelligent path speculation to reconstruct the packet paths with high reconstruction ratio. We propose a novel analytical model to analyze the performance of Pathfinder. We further calculate Pathfinder compared with two most related approaches using traces from a large scale deployment and extensive simulations by means of graph. Results show that Pathfinder outperforms existing approaches, achieving both high reconstruction ratio and low transmission cost compared to MNT.
Estimating Customer Potential Value using panel data of a Spanish bank

The main goal of this paper is the calculation of a multi-product model of Customer Potential Value using the Probit method. The results of this first analysis are used to perform an ex-post segmentation of customers, whose output can be employed to improve Customer Relationship Management strategies of the companies. Our research contributes to the consumer behaviour literature insofar as, according to our knowledge, no previous work has examined collectively the proposed drivers of Customer Potential Value in a multi-services retailer. To achieve these objectives, we use a panel data of a Spanish bank. The results allow us to confirm the influence of a set of behavioural variables on the ownership of different banking products and identify those customers whose value is higher and lower through the calculation of Customer Potential Value.
ANALYSIS OF THE RETURNS AND VOLATILITY OF THE ENVIRONMENTAL STOCK LEADERS

The last years have been faced with a blasting development of the Socially Responsible Investments (SRI) worldwide even though the economic environment has been shaken by a global economic and financial crisis. The aim of this paper is to analyze the return and risk characteristics of the sustainably managed companies that pay particular attention to the environment responsibility in comparison with those that pay more attention to the corporate governance and respectively to the social responsibility. These characteristics are useful both to the individual and institutional investors as well as to the portfolio managers. For the comparative analysis we started from the study of descriptive characteristics of return and risk of indices portfolios of the environmental social and governance stock leaders and we focused on their univariate econometric modelling by means of the heteroskedastic models. The studies undertaken until now are centered on the performance obtained by the portfolios of sustainable indices and on the modelling of the volatility of sustainable indices. We would like to investigate the characteristics of return and risk of the assets of the sustainably managed companies that could attract active investors towards the sustainably managed companies that pay particular attention to the environment responsibility in comparison with those paying increased attention to the corporate governance and respectively to the social responsibility.
ASSOCIATION FOR CONSUMER RESEARCH

The market related to so-called extreme sports, such as rock climbing and sky diving, has burgeoned since the 1990s. Consumer behavior research has linked the personality trait of sensation seeking (SS) with involvement in the above sports. However, work on participation in risky sports has not thoroughly examined the influence of personality and subsequent emotional response, on behavioral intentions in this context. The current study investigated the effects of the SS personality trait, along with demographics, on novice artificial wall climbers’ (n=241) emotional responses (PAD scale: pleasure-arousal-dominance) and related behavioral intentions to climb again. Results suggest participants’ emotions (e.g., arousal) and future intentions to climb are both a significant function of personality and gender. Theoretical Background The consumption of risky sports has dramatically increased over the past few years (Shoham, Rose, & Kahle, 1998). For instance, participation in artificial climbing walls has grown by roughly 60% in the three-year period from 1999 to 2001, while participation in some classic team sports, such as baseball, dropped by 6% (Flagg, 2005). Arousal theory suggests that every individual has a characteristic optimum stimulation level (OSL) and this is the foundation of personality (Raju, 1980; Zuckerman, 1988). Based upon the OSL paradigm, Zuckerman (1979) defined sensation seeking as a trait
Dual-band metamaterial-inspired small monopole antenna for WiFi applications

A simple dual-band metamaterial-inspired small monopole antenna is proposed for WiFi applications. In addition to the regular monopole resonance, the metamaterial-inspired loading is exploited to create a second resonance for the lower WiFi band while maintaining the antenna's small form-factor. The measured S parameters and radiation patterns show that the proposed design is suitable for emerging WLAN applications.
PERIODIC SOLUTIONS OF SECOND-ORDER LIÉNARD EQUATIONS WITH p-LAPLACIAN-LIKE OPERATORS

and its special case have been studied by many researchers, we refer the readers to [1, 3, 4, 6, 7, 9–12] and the references therein. Let us consider the so-called one-dimensional p-Laplacian operator (φp(u′))′, where p > 1 and φp :R→R is given by φp(s)= |s|p−2s for s = 0 and φp(0)= 0. Periodic boundary conditions containing this operator have been considered in [2, 5]. In [8], Manásevich and Mawhin investigated the existence of periodic solutions to some system cases involving the fairly general vector-valued operator φ. They considerd the boundary value problem
OLD FRENCH AND ROMANIAN DECLENSIONS FROM A WORD AND PARADIGM PERSPECTIVE AND THE NOTION OF "DEFAULT SYNCRETISM"

Old French and Romanian nominal inflections or declensions share the property of being apparently uncomplicated as their paradigms consist in only two forms at most: a base form and an inflected form. This outward simplicity, however, results from complex syncretisms. In Old French masculine nouns, the singular subject case and the plural object case are identically inflected, whereas the singular object and the plural subject cases are identical base forms; in Romanian feminine nouns, the singular genitive-dative and the two plural case forms are the same. Such syncretisms raise a descriptive and theoretical issue as they appear to be neither semantically motivated nor fully arbitrary. Drawing on the conceptual and formalizing resources of Word and Paradigm (WP) theory and Paradigm Function Morphology (PFM), the present essay attempts to solve the issue by assuming a third kind of syncretism that involves not the meaningful content of features, but their DEFAULT value. At the same time, it proposes a nearly full treatment of Old French and Romanian declensions in PFM terms.
Managerial Perceptions of Climate of Innovation and Organizational Commitment in Private Sector Organizations in Ethiopia.

Innovation is the process of making change to something established, by introducing something new. It may refer to both radical and incremental changes to products, processes or services. In organizations, it refers to creativity, which ultimately should improve the standards of organizations as well as commitment of its members. The present Indian perspective highlights the importance of innovative support climate for enhancing organizational commitment in Indian organizations. The study examined the relationships between managerial perceptions of the climate for innovation and the affective and continuance organizational commitment (OC) among managerial personnel in manufacturing and services organizations in Ethiopia. It was expected that the perceptions of the climate for innovation would be positively related with the levels of the organizational commitment among the managerial personnel of the organizations under study. The study was conducted on a sample of 100 managerial personnel from a large-scale private sector organizations in Ethiopia. Results demonstrated that among the four dimensions of innovation, creativity and barriers were positively related with the affective OC, while, novelty was negatively related with the affective OC. Further, creativity was positively related with the continuance OC, but, novelty was negatively related with the continuance OC. Stepwise regression analysis showed that, among the dimensions of innovation-supportive climate, creativity positively predicted the affective OC, while, novelty negatively predicted the affective OC. Accordingly, creativity was also found to predict the continuance OC positively, while, recognition and novelty predicted the continuance OC negatively. The results highlight the importance of climate for innovative support for increasing the organizational commitment among managerial personnel in organizations.
Flow burst‐induced Kelvin‐Helmholtz waves in the terrestrial magnetotail

The Kelvin‐Helmholtz instability (KHI) on the boundary of a flow channel in the Earth's plasma sheet is investigated using Cluster and Double Star TC1 data. It is shown that when Cluster moves into the flow channel the magnetometer measures strong oscillations of the magnetic field, that increase as the spacecraft move further into the flow channel. These waves are identified as Kelvin Helmholtz waves. DoubleStar TC1, closer to the Earth, also observes these waves when entering the flow channel but at larger amplitude and with only little flow. The increase in wave amplitude agrees with the KHI wave growth. It is argued that the development of the KHI can play a major rôle in flow braking in the magnetotail, which is an important aspect of magnetotail dynamics. The large amount of kinetic energy released by a reconnection event or bursty bulk flow gets converted to other kinds of energy such that in the near Earth region the flow is stopped.
KLF4 Genome: A double edged sword

Kruppel like factor 4 (KLF4), member of SP1/KLF transcription factor family is characterized by three extremely conserved C2H2-type zinc-finger motifs at its carboxyl boundary that are crucial for its interaction with target DNA. Participation of KLF4 in the control of proliferation, differentiation and apoptosis are suggestive for KLF4 critical role in tumorigenesis. Depending on the genetic and cellular context, KLF4 gene acts as both oncogene and tumor-suppressor. KLF4 is a significant regulator in reprogramming of somatic cells to pluripotent cells that can give rise to all of the cell types that make up the body. Multiple in vitro and in vivo studies have shown inhibitory role of KLF4 in epithelialmesenchymal transition (EMT) in various cancer types and loss of KLF4 expression during EMT significantly correlates with tumor angiogenesis, metastasis and aggressiveness. The manuscript updates the interrelationship that exists between epigenomic regulation of KLF4, its effector genes and oncogenic transformation.
Entrepreneurship and Entrepreneurs in an Islamic Context

This paper is a modest contribution to the literature on entrepreneurship and entrepreneurs from an Islamic perspective. Along with debates on the role of religion, and the increasing importance of ethics, social responsibility in modern business, discussing the case of entrepreneurship in an Islamic context is quite opportune. After outlining the foundation of Islamic entrepreneurship, the author then explains the positive features and the applicability. The approach adopts the representation of human beings, mostly by physical and spiritual dimensions, with the latter dimension having a specific interpretation in Islam. The outcome of the analysis is that, subject to good understanding, and correct implementation, principles and rules of Islam offer real possibilities of enhancing various types of businesses. Moreover, that can be possible in a balanced way, i.e., making business profit and at the same time targeting spiritual rewards. Noteworthy, this practice of doing business could help Muslim entrepreneurs avoid deviations from generally agreed business ethics and spirituality, as based on the lastly sent Holy Scriptures.
