Rotating Arm-Based Experimental Study on Droplet Behavior in the Shoulder Region of an Aircraft Aerodynamic Surface

An experimental study has been performed on water droplet deformation in the shoulder region of an airfoil. The experiments have been carried out in a rotating arm facility 2.2 m long and able to rotate up to 400 rpm (90 m/s). A blunt airfoil model (chord length equal to 0.468 m) was placed at the end of the arm. A droplet generator was used to generate a stream of water droplets with an initial diameter of 1000 μm. An imaging system was set up to record the trajectories and deformations of the droplets in three different regions close to the airfoil shoulder. The base flow field was characterized using a particle image velocimetry system. The experiments show that droplet deformation results in the shoulder region of the airfoil are different from those pertaining to the leading edge region. In particular, droplets in the shoulder region tend to rotate to the direction of the incoming airfoil which generates an interference effect between the droplets that make up the stream. These differences have been quantified applying an existing theoretical model specifically developed for the leading edge region to the results obtained in the present study.
Predicting Performance and Inflammation Responses to Stereotype Threat

We experimentally tested whether negative stereotypes linked to lower socioeconomic status (SES), in addition to impairing academic performance (Croizet & Claire, 1998), instigate inflammation processes that are implicated in numerous disease processes. In Study 1, verbal test performance and activation of inflammation processes (measured by levels of an inflammatory protein, Interleukin-6 [IL-6]) varied as a function of SES and test framing (i.e., diagnostic vs. nondiagnostic of intellectual ability), with low SES students underperforming and exhibiting greater IL-6 production in the ‘‘diagnostic’’ condition. In Study 2, students expected their verbal exam performance to be compared to peers of higher or lower SES. Low SES students in the upward comparison condition displayed the greatest inflammatory response and worst test performance. Across both studies, different facets of SES predicted vulnerability to negative outcomes, such that low early life SES predicted heightened inflammation responses, while low current SES predicted impaired academic performance.
DETERMI A TS OF I VESTME T FLOWS

The purpose of the paper is to test the long-run steady state of growth factors hypothesized to influence U.S. manufacturing investment flows. These factors include agglomeration, market structure, labor, infrastructure, and fiscal policy. Spatial cross-regressive and spatial Durbin models are used to measure the spatial interaction of investment flows. Spatial spillovers are found to be of a competitive nature at the state level, implying that a factor which attracts more investment to a particular state is associated with lower investments in neighboring states. Investment flows to states with higher market demand, more productive labor, and more localized agglomeration of manufacturing activity.
The social location of the Matthean community

Individuals or societies are always pursuing their own interests. Interests are identified in terms of domination and the retention of the status quo against subordination and the pursuit of change. The conflict between the first-century (after AD 70) Pharisees and the Matthean community is identified as a conflict of interests. The Pharisees functioned as to retain the Roman rulers and maintain the status quo, and attempted to reconcile the Jewish community. The Matthean community predominantly comprised the urban non-elites and rural peasants, thus the marginalized in agrarian society. They pursued a new identity and challenged the values of the Jewish leaders. The mere fact ofit[ existence as a community in the process of departing from the Jewish mainstream was a threat to the authority of the Pharisees. The fact that the community was still very close to Judaism was cause for intense conflict.
Social networking sites in the UAE emerging market: in pursuit of knowledge about users

Purpose: Social networking sites have become embedded in everyday life. Additionally, they have become a research focus indicated by the burgeoning literature. However, little is known about social networking site users in emerging markets. This paper focuses on this gap and begins to address the question: What is the reach of social networking sites in an east-meets-west emerging market? Design: The information presented, herein, is the exploratory phase of an empirical study guided by three objectives that consider user demographics and the constructs of purpose and privacy: (1) to what extent do demographic factors influence the use of social networking sites, (2) to what extent does purpose play a role in use of social networking sites and (3) to what extent is privacy a concern when using social networking sites? Research Implications: Two expert interviews and an extensive literature review support the eleven suggested propositions for the empirical stage to follow. Findings from the interviews acknowledge that little is known about users in the UAE emerging market, thus, creating a need for information relevant to marketers who use the medium to reach consumers and for additional academic research. Originality/Value: The UAE setting provides knowledge about the influence of demographics such as age and nationality as well as including the cultural impact on purpose and privacy. The findings ultimately contribute to understanding users within the wider population of an emerging market which has been a slow-to-close gap in the literature.
Governance of sub-Saharan African companies in the era of corporate social responsibility: The case of Cameroonian companies

While most studies of corporate social responsibility governance is particularly relevant in companies in developed countries, however, very few publications have focused on the translation of this corporate social responsibility into sub-Saharan companies in Africa in general and Cameroon in particular . The stakeholder theory, the theory of resource dependence and the neo-institutional theory fit the corporate social responsibility in plural governance where shareholders are no longer the unique partners and in which actors are involved in decisions and business operations. Therefore, can this concept of corporate social responsibility be transposed in African companies where the modes of social organization, economic and political systems are far west? From the data collected on a sample of 260 companies in Cameroon, this paper shows that the rate of social responsibility is low. However, the relationship tested between social responsibility and type of business was significant. This result shows a strong tendency to social responsibility actions in subsidiaries of multinational firms and some domestic firms in sectors where compliance is a legal requirement. The analysis of social responsibility in the Cameroonian companies helps conclude that we can achieve this goal if companies highlight their concern for legitimacy and ethics and that the state supports them through a legislative and regulatory framework.

STATISTIC AND EXPERIMENTAL ECONOMICS

This paper will be short overview of the use of experiments in economics and changing paradigm about homo economicus by showing some aspect of behavioral economics as growing field of science, relationship between behavioral economics and experimental economics and show some application of those for example on labor market. Moreover, as science (include psychology and behavioral economics) starts to be more spread in common knowledge and science results starts to be known in business and organizations, implications of economics experiments and field studies are use in important decision making as well as every day organization live. Experiments shows how behavioral economic works. Experiments and field studies are base sources for this discipline. Contrasts with standards economics approach which is mostly mathematical or statistical analysis (although experimental economics uses statistical methods too). To highlight potential it will be introduce some of experiments (some of them organized in The Laboratory of Experimental Economics at The University of Economics in
Prediction of output parameters in wire electrical discharge machining of EN-31 steel by artificial neural networks

The objective of this work is to predict the effect of input parameters on output parameters using artificial neural network in wire electrical discharge machining. The input variables considered are peak current, pulse on time, flushing pressure of dielectric, pulse off time, wire tension and wire feed rate. The output variables taken into consideration are dimensional deviation and material removal rate. Workpiece used in the study is of EN-31 steel. Wire electrical discharge machining is a thermal cum electrical process and uses the electrical and thermal energy for cutting materials. Wire electrical discharge machining is utilised for cutting electrically conductive materials, which are difficult to machine with conventional machining methods. This process uses discrete electrical discharges between continuously travelling wire (tool) and the workpiece for cutting the workpiece. In this work, artificial neural networks are used for prediction of output parameters. Artificial neural networks have a highly connected set of nodes or processing elements that operate in parallel. Artificial neural networks can be trained using input and output data and can be used to predict data for new input values.

An Investigation of the Relationship between Mathematics Performance of Students in a Non-Routine Problem, according to Grade and Gender

This study aims to investigate the relationship between performance of students in solving a proportional reasoning problem and the variables of gender and grade level, respectively. The participants in the study included 540 students (320 girls and 220 boys) in the first, second, and third grades of junior high school in Isfahan's schools. Students were asked to respond to non-routine problems in a special sheet that had been prepared in advance. The strategies used by students in the answer sheets were then analysed by using a theoretical framework from the research literature in mathematics education, and classified into seven categories as follows: no answer, sheer collective, non-real, procedural, transition, novice and professional strategies. Kruskal-Wallis and Mann and Whitney statistics were used to evaluate the significance of the effects of each grade and gender factors on the student performance. The results showed that the overall performance of boys was better than that of girls. Also performance of the first grade students was significantly higher than the second and third grade students' performance. Other differences were not significant.
Knowledge Sharing Impact Factors Selection for Research Supervision

Due to the impact of globalization, universities increasingly face new challenges and opportunities. Accordingly, they ought to be more innovative. Therefore, knowledge-sharing between students and supervisors is vital in universities. This research aims to systematically analyse and extract all the knowledge-sharing impact factors and choose adaptable ones for a research supervision domain. We carried out a literature review of empirical studies on knowledge-sharing quantitative research, published during the last decade (2000–2012). We have recognized 29 primary studies related to the purpose of this research. After considering these studies, we discovered the following, namely that, the ability of students to share, the culture of the respective university, knowledge-sharing social networks, flexible structure and design, supervisor support, learning strategies and IT systems are adaptable. In addition, it was found that suitable knowledge-sharing factors are not only supported by knowledge management model for research supervision and other research supervision models, but also have enough iteration in literature studies to support them.

Zur Auslegung von Schwerkrafteindickern

For the evaluation of the thickener area, some methods have been developed which are based on discontinuous tests in settling vessels and experimentally yield the settling of the mudline as a function of time. But it has become obvious that not only the comparison of thickener areas determined by different methods often reveals considerable differences but also the comparison with results achieved in industrial thickeners can show substantial differences. Above all, this is true if it refers to flocculated slurries. In this paper, first of all the present state of the design methods is briefly discussed for the different subprocesses of sedimentation. More in detail, the settling test and its interpretation as basis for design is described and besides emphasized that methods which are based upon the Kynch analysis and, therefore, only need one settling curve for design should be preferred, because in this connection it is assumed that the settling velocity only depends on the respective local solids concentration. If the tests are performed under conditions which with regard to the compression phenomena largely correspond to those in industrial thickeners, then an evaluation on the basis of the Kynch analysis including the compression zone can be made. Relevant to this, in the last years methods have been developed which these preconditions evidently meet well. Pour le dimensionnement des epaississeurs par gravite on a mis au point toute une serie de methodes basees sur des essais effectues a l'aide de cylindres de decantation et permettant de determiner experimentalement la discontinuite de la concentration (surface de separation) entre la zone du liquide de decantation et la zone situee au-dessous de celle-ci, en fonction du temps. Il s'est avere non seulement que les surfaces de sedimentation determinees selon ces methodes peuvent differer notablement les unes des autres, mais qu'il peut y avoir des differences considerables par rapport aux resultats possibles a l'echelle industrielle, surtout lorsqu'il s'agit de suspensions floculees. Cet article explique d'abord brievement l'etat actuel de developpement des methodes de dimensionnement des differents processus partiels de sedimentation. Puis il traite, de facon plus detaillee, l'essai de decantation et son evaluation, qui doit servir de base au dimensionnement, tout en demontrant qu'en ce qui concerne les suspensions floculees, il faut donner preference aux methodes basees sur l'analyse de Kynch, raison pour laquelle elles ne requierent qu'une seule courbe de decantation, en supposant que la vitesse de decantation depend seulement de la concentration locale des solides. Si ces essais sont effectues dans des conditions qui correspondent, autant que possible, pour ce qui est des phenomenes de compression, aux conditions usuelles des epaississeurs industriels, on peut effectuer l'evaluation correspondante a l'aide de l'analyse de Kynch, y compris la zone de compression. A cet effet, on a mis au point recemment des methodes satisfaisant a ces exigences.

Developing Customized Employee Engagement Measure in an Indonesian Large Company: Procedure, Validity, and Reliability

Companies have been concerned on measurement and improvement of their employees’ engagement using various conceptual models. Since every company has their own specific vision, mission, and values, customization is needed to measure employee engagement objectively. One of the biggest state-owned company in Indonesia develops a specific model of employee engagement, consisted of 12-dimensions. Those dimensions have been operationalized in order to build a set of questionnaire to measure employee engagement. This study elaborates the procedure taken to create, validate, and testing the reliability of the measure. We administered the newly designed questionnaire (38 items measuring 12-dimensions) as well as Gallup Employee Engagement and Aon Hewitt questionnaires to 869 employees of the company. Significant correlations between measures, significant item-total item correlations, factorial robustness, and discriminative power confirmed the validity of the measure. Internal consistency, test-retest reliability, and Cronbach Alpha confirmed the reliability of the measure. These multiple sources of evidence are discussed.
