Analysts point to increasingly automated manufacturing processes, changing domestic demand factors, outsourcing, and over confidence in service export surplnses. However, Asian and European competitors, undergoing the same pressures, have been able to maintain a healthy percentage of their GDP in manufacturing by growing high techjobs while the United States continues to fall behind, Perhaps the most flmdamental and overlooked contribution to this decline is the lackluster performance of the United States education system. After comparing the performance of US students to that of the other G-8 nations in the critical disciplines of math and science literacy, US students rank last. Furthermore, the most recent PISA test results show US students rank in the bottom half of 30 participating nations in the ability to apply math and science concepts to real world problems. This is particularly troubling when one considers that among the compared nations, the US spends the most on math and science teacher compensation. If the US intends to successfully compete in the global manufacturing arena, significant changes to the education system must be enacted. A new strategy aligning the system with real world demands should begin with a national initiative to increase Pre-K enrollments, a paradigm shift from liberal arts to math, science, problem solving and critical thinking, standardized policies aligning high school graduation requirements with college and work place expectations, and standardized college and career readiness assessment programs. These steps combined with more rigorous secondary education teacher certifications, continued education and involvement with universities and manufacturing f＇mns within the community, should more adeq^tely prepare high school students for further study or to enter the skilled workforce. At the post secondary level, federal and state funding should be targeted to R＆D programs specificly to industrial design, engineering, and alternative energy. Industry investment in such programs should be federally incentivized to foster cooperative relationships between business and academia. Such relationships will ensure faculty spend time focusing on how their discipline relates to manufacturing and instilling the necessary skill sets, knowledge and abilities which graduates will need to compete in the global market. Such a revised system will position the US to create and keep high paying manufacturing positions on its way to sustainable economic growth.展开更多

In order to verify the centesimal composition, these animals caught in Sepetiba Bay （Rio de Janeiro, Brazil）, 20 samples of Ucides cordatus, Cardisoma guanhumi, Menippe nodifrons, Callinectes danae and C. exaperatus had their edible and waste parts （shells and hepatopancreas） analyzed in the Laboratory of Bromatology of the UFRRJ. The analysis revealed that the meat of crustaceans is protein （12.68% to 25.56%） and low in fat （0.37% to 0.67%）, sticking to a more demanding consumer market for thin products; the waste has already presented a protein content ranging from 15.75% to 27.64% and fat from 0.75% to 3.27%, with values of calcium （17.96% to 25.23%） and phosphorus （0.93% to 1.55%）, setting a precedent for use in animal feed through future studies in area.展开更多

It was an interdisciplinary approach of ecological and cultural views of biodiversity. Special educational material was prepared with photos and texts of archaeological excavations and field sampling which was used in real and virtual environment, in t~ discovery teaching of Natural Sciences and History subjects. Students, in a scientific research project with constructive teachings, followed the procedures by which scientists gather, analyze, synthesize, process and evaluate information of organisms of Crete since 4000 years. Crete is located between the natural limits of three continents, having the unique privilege to host permanently or in migration, distinctive species of these three continents. After having the research questions, teachers collected the educational material, organized the work groups, implemented the didactic intervention in the classroom, had the field sampling of plants, recognized the synchronous local and scientific names of the plants, constructed the botany book, photographed the collected organisms and all the concentrated material was delivered to the team members.展开更多

While researchers have applied different social science perspectives to analyze cross-border higher education and IBCs, they usually emphasize developed countries as exporters and developing countries as importers of higher education. The phenomenon of developing countries as exporters of higher education has seldom been looked at so far in the research. This paper first describes the current development of IBCs, then illustrates what social science perspectives have been used on this topic, followed by how push-pull theory relates to developing countries being exporters of IBCs. The paper aims to combine E.S. Lee＇s push-pull theory and Gu＇s push-pull framework to analyze the push and pull factors in their advertisement and marketing claims when higher education institutions （HEIs） from developing countries plan to establish branch campuses in foreign countries. Soochow University in Laos is used as a case study. Furthermore, intermediate barriers and solutions are also identified in this case study. However, this case study has its own uniqueness and only serves heuristic for future research.展开更多

Particularly, it can predict and estimate the future, playing a great role in promoting the rapid development of science and technology as well as the management of market economy. In general, mathematics does not directly deal with the objective conditions on the management of market economy. In order to use mathematics to solve problems in the field of the management of market economic, it is necessary to carry out mathematical economic modeling.展开更多

From this point, it is important to encourage the development of the basic techniques of control systems, electronics and communication in order to produce knowledge in the mechatronic field and so apply them to industry. Considering the relevance of this subject, the students of Federal University of Para-Campus Tucumi through the Research Group of Electrical and Mechanical Systems apply their knowledge in multidisciplinary engineering fields in order to generate knowledge from creative techniques using low cost materials, together with the encouragement of social and environmental responsibility which is very important nowadays. At the same time, targeting the needs of the labor market, this work aims to foster in students the skills and requirements through team projects and innovative methods. Therefore, this paper presents a mechanical manipulator, where their operating characteristics are based on industrial robots in the literature, powered by DC （direct current） motors and fully developed from reusable materials. By adding a developed control from the Arduino, prototyping platform with an electronic strategic offers through the internet the long-distance control convenience.展开更多

Vrr^＊（P）could be further expressed as a uniformly convergent expansion series in the domain outside the inner sphere, because rrV（P）^＊ could be expressed as a uniformly convergent spherical harmonic expansion series due to its regularity and harmony in that domain. In another aspect, the fictitious field V^＊（P） defined in the domain outside the inner sphere, which coincides with the real field V（P） in the domain outside the Earth, could be also expressed as a spherical harmonic expansion series. Then, the harmonic coefficients contained in the series expressing V^＊（P） can be determined, and consequently the real field V（P） is recovered. Preliminary simulation calculations show that the second radial gradient field Vrr（P） could be recovered based only on the second radial derivative V（P）｜δs given on the satellite boundary. Concerning the final recovery of the potential field V（P） based only on the boundary value Vrr （P）｜δs, the simulation tests are still in process.展开更多
