A constru??o psicossocial da competi??o: o engano na cumplicidade de uma falsa vida
Caniato, Angela Maria Pires;Rodrigues, Samara Megume;
Psicologia & Sociedade , 2012, DOI: 10.1590/S0102-71822012000100004
Abstract: the present work analyses competition and its ideological spread in contemporaneity. first we have identified its matrix in private property, what enabled the use of this procedure as the stimulus of capitalism development. in this path, science has presented itself as a component of legitimation and intensification. intending to increase human work exploitation, nowadays competition mixes itself with the cynic speech of cooperativeness. in the reproduction of the competition among individuals are present some subjective elements as authoritarian submission to the social, to projectivity, to sadomasochism and to the reified thought (ticket's mindedness). concerning affection, competition is sustained by envy, which still adheres, via cultural industry, the individuals to consumerism. this article is a literature review research, whose theoretical bases are the freudian psychoanalysis and critical theory of the frankfurt school, especially adorno and horkheimer.
Factors Influencing Students’ Choice of Elective Science Courses: A Case Study from the American University of Sharjah  [PDF]

Abstract: Scientific studies in higher education are becoming an increasing matter of discussion. The Ameri- can University of Sharjah (AUS) encourages the scientific literacy of students who are not enrolled in science or engineering majors by including two required science courses in the curriculum. The courses of choice include biology, chemistry, environmental sciences, astronomy and physics. This study investigates the factors that contribute to students’ choice when selecting science courses at AUS. A survey comprised of open-ended questions as well as quantitative enquiries was administered to students enrolled in environmental science (ENV 100), aiming to investigate the main reason behind their choice. The results of this two year study showed significantly positive attitudes toward the course contents and the benefit of the course towards their future careers. Furthermore, it reveals that students are highly influenced by previous experiences with subjects, professors’ popularity, peer recommendation, their abilities in memorization, and skills in math. The study reveals that the main concern for students is related to the high amount of information and details that the course content covers. In addition, the possibility of obtaining a higher grade was also studied by observing the grade point average (GPA) for science courses over a period of four years. Nonetheless, the main factor for course choice was their genuine interest for the subject matter, which is this case study, was the environmental studies course.
Aware Diffusion: A Semi-Holistic Routing Protocol for Wireless Sensor Networks  [PDF]
Kamil Samara, Hossein Hosseini
Wireless Sensor Network (WSN) , 2016, DOI: 10.4236/wsn.2016.83004
Abstract: Routing is a challenging task in Wireless Sensor Networks (WSNs) due to the limitation in energy and hardware capabilities in WSN nodes. This challenge prompted researchers to develop routing protocols that satisfy WSNs needs. The main design objectives are reliable delivery, low energy consumption, and prolonging network lifetime. In WSNs, routing is based on local information among neighboring nodes. Routing decisions are made locally; each node will select the next hop without any clue about the other nodes on the path. Although a full knowledge about the network yields better routing, that is not feasible in WSNs due to memory limitation and to the high traffic needed to collect the needed data about all the nodes in the network. As an effort to try to overcome this disadvantage, we are proposing in this paper aware diffusion routing protocol. Aware diffusion follows a semi-holistic approach by collecting data about the available paths and uses these data to enforce healthier paths using machine learning. The data gathering is done by adding a new stage called data collection stage. In this stage, the protocol designer can determine which parameters to collect then use these parameters in enforcing the best path according to certain criteria. In our implementation of this paradigm, we are collecting total energy on the path, lowest energy level on the path, and hop count. Again, the data collected is designer and application specific. The collected data will be used to compare available paths using non-incremental learning, and the outcome will be preferring paths that meet the designer criteria. In our case, healthier and shorter paths are preferred, which will result in less power consumption, higher delivery rate, and longer network life since healthier and fewer nodes will be doing the work.
Annals of the University of Petrosani : Economics , 2010,
Abstract: The main purpose of evaluation is to determine the financial position and the outcome of the entity’s activity. With the intensification of the phenomena of globalization of economies and financial markets and the emergence of phenomena such as inflation, it began to be more often used the assessment based on the current value and, in particular, on the fair value. The users of the financial statements must always be taken into when selecting a basis of evaluation. Internationally, we can observe the tendency that, by the use of a certain bases of evaluation, to respond favourably to the needs of a various range of users; a balance must be assured between the relevance of the information (their usefulness in decision-making) and their reliability (their objectivity).

Abstract: Vehicular Ad hoc Network security is one of the hottest topics of research in the field of network security. One of the ultimate goals in the design of such networking is to resist various malicious abuses and security attacks. In this research new security mechanism is proposed to reduce the channel load resulted from frequent warning broadcasting happened in the adversary discovery process a€“ Accusation Report (AR) - which produces a heavy channel load from all the vehicles in the road to report about any new adversary disovery. Furthermore, this mechanism will replace the Certificate Revocation List (CRL), which cause long delay and high load on the channel with Local Revocation List (LRL) which will make it fast and easy in the adversary discovery process.

Computer Science , 2012, DOI: 10.1109/NETAPPS.2010.17
Abstract: Vehicular Ad Hoc Networks (VANET) has mostly gained the attention of today's research efforts, while current solutions to achieve secure VANET, to protect the network from adversary and attacks still not enough, trying to reach a satisfactory level, for the driver and manufacturer to achieve safety of life and infotainment. The need for a robust VANET networks is strongly dependent on their security and privacy features, which will be discussed in this paper. In this paper a various types of security problems and challenges of VANET been analyzed and discussed; we also discuss a set of solutions presented to solve these challenges and problems.

Computer Science , 2013,
Abstract: Vehicular Ad hoc Networks (VANET) is one of the most challenging research areas in the field of Mobile Ad Hoc Networks. In this research, we propose a new mechanism for increasing network visibility, by taking the information gained from periodic safety messages (beacons), and inserting it into a 'neighbor' table. The table will be propagated to all neighbors giving a wider vision for each vehicle belonging to the network. It will also decrease the risk of collision at road junctions as each vehicle will have prior knowledge oncoming vehicles before reaching the junction.

Prenatal testing and termination of future pregnancies in Arab mothers of children with severe defects: impact of Moslem cleric or physician on the decision making  [PDF]
Lutfi Jaber, Gabrielle J. Halpern, Samer Samara
Open Journal of Genetics (OJGen) , 2011, DOI: 10.4236/ojgen.2011.13010
Abstract: The authors investigated: 1) How many of 250 Israeli Arab mothers (50% in consanguineous marriages) of babies with severe congenital anomalies had undergone prenatal testing during pregnancy, and how many had refused termination of pregnancy (TOP) when recommended; 2) Why TOP had been refused; 3) Attitudes regarding prenatal testing and TOP in future pregnancies; and 4) Whether the women would have changed their decision had they been able to talk to a Moslem cleric or Moslem doctor in addition to the regular personnel. Eighty seven (35%) refused to even consider TOP, 55 (22%) agreed to undergo TOP, and 87 (35%) agreed provided the procedure would be performed before 120 days gestation. The remainder were undecided. Of 195 women, the addition of a Moslem religious cleric or physician to the Committee would influence 89 (46%) and 55 (28%), respectively, to change their opinion and agree to TOP, and 26 (13%) and 10 (5%), respectively, to change their opinion and agree to TOP prior to 120 days of gestation. The remainder either continued to refuse TOP or were undecided.
