Security in modern daily life, which is interrupted by explosions, catastrophes, and terrorist acts, is becoming one ofthe scarce benefits of existence; security is the result of cooperative efforts involving authorities, intelligence services, and the rest of people who save society from terrorists and other robbers of security. “The atti- tude toward security can be mediated by the context a person reads into this notion and can differ in regard to ways of achieving it” (Dontsov, Zinchenko, & Zotova, 2013, p. 99). As a rule, we start to fight against a lack of security only after one more tragedy has happened. Measures to prevent and foresee this dreadful phenomenon still require great efforts on the part of psychologists, sociologists, ethnologists, and ethnopsychologists, who not only should find the answer to the problem and carry out monitoring but also should formulate concrete recommendations for state and nonstate organizations. People have a common interest at the least because they face global risks shared by the majority. Contingent worlds of interactions and communications are made up of events common for this or that group of people (Smirnov, 2003, pp. 29–30). If we comprehend reality in this way, we can assume that people’s striving for security not only is one ofthe conditions of coexistence but also indicates their readiness for co-being, meaning-making, and interaction. Zotova indicates that “it is in human nature to feel security/insecurity on the basis of alarming signals, the perception of sense organs, instinctive reactions, and intu- ition; that is, in this light security (insecurity) means an individual subjective idea of whether there are threats to existence or not” (Zotova, 2012, p. 111).
The weather information gives the evidence about the hourly weather conditions for the day that we want to predict. But what would happen if were given to the model information about the time ofthe day, the day ofthe year and the position ofthe sun when those weather conditions occur? Maybe the model would identify that at 08 h, the radiation and the temperature are low, but in the middle ofthe day, these two variables are at the highest level. Or, for the latter case, the sun is higher than it was earlier. To explore this idea, it was decided to add the information of azimuth, elevation angle and Solar time. As verified in Figure 15, the additional inputs had a positive impact on the forecasting error, with the test 7 being the more accurate one. This time, the test with more input variables was not the one with the best result, therefore is fair to conclude that more inputs do not necessarily mean a better result, it is important to know well the variables that enter the model. To explain better, if the added input variables are not correlated with the variable we are trying to predict they do not add relevant information to the model. On the other hand, if they are highly correlated with other input variables, they do not add new information. In both cases, they do not add explanatory power to the model.
We a d o p t e d t h e A H P a p p r o a c h t o develop the framework used to evaluate the effectiveness of practices supported by the iCan e-learning platform. Therefore, we can obtain the weights of each dimension (i.e., individual learning, group sharing and learning performance) and the weights of criteria (i.e., items) ofthe associated dimension. There are some researches evaluating the e-learning platform by adopting the AHP approach. Chao and Chen (2009) utilize the consistent fuzzy preference relations (CFPR) in the AHP model to examine and summarize the key factors in order to rate the weights and evaluate the effectiveness of a distance e-learning system. The rating results provide teachers and decision- makers in schools with important information for improving e-learning practice in the future.

In this article, we offer an alternative concept of research through the acquisition of emic and etic knowledge for implementing ethnomodeling, which aims to connect the cultural aspects of mathematics with its academic aspects. From this perspective, the use of emic and etic approaches facilitates the translation of problem situations present in the systems, extracted fromthe reality of distinct cultural groups, into academic mathematics. Emic knowledge is essential to the intuitive and empathic understanding ofthe mathematical practices developed by a particular cultural group, while etic knowledge is essential for comparing these practices. We also discuss the dialectical approach to research on ethnomodeling, which uses both emic and etic knowledge through a dialogic process, aiding a fuller understanding ofthe knowledge ofthe mathematical practices developed by members of different cultural groups. In this sense, emic knowledge is a valuable source of inspiration for the development of etic hypotheses. In such a dialectical context, a mathematics curriculum based on the ethnomodeling perspective favors the generation of mathematical knowledge to ensure the balanced integration ofthe effective mastery of educational objectives, which are essential for the recognition and use of students’ emic knowledge.
The great majority ofthe KM and search tools on the market are server-based enterprise systems. As such, they are often designed top-down, centralized, inflexible and slow to respond to change. There has been numerous articles published on the role of IT and KM systems in organizations but there is a lack of research into KM tools for individuals and server-less KM tools/systems. By adopting a bottom-up approach, this research focuses on tools that assist the Individual Knowledge Worker (IKW) who, in today’s competitive knowledge-based society, has a constant need to capture, categorize and locate/distribute knowledge on multiple devices and with multiple parties. Furthermore, knowledge sharing between IKWs often extends across organizational boundaries. As a result, personal KM tools have very different characteristics to the enterprise KM tools mentioned above. At the group level, the impact of Peer-to-Peer (P2P) computing on Knowledge Management has been specifically identified as file sharing, distributed content networks, collaboration, and search. Potential applications for P2PKM systems include, among others, E-Learning in higher and distance education, real-time collaborations and battle simulations in defense, collaborative product development, business process automation, and E-business payment systems, and many others.
Several of these questions and others were discussed in round tables in the scope of several meetings held by the fractional calculus community [18,19]. Nevertheless, present day state of affairs reveals that they were not sufficient to stimulate all researchers for a systematic definition ofthe fundamental concepts. We observe the emergence of a plethora of assumed new operators that are named as novel or generalised fractional derivatives. Often it is also claimed that such operators fit better the experimental data. Obviously, from an application point of view, such lightly written words would need a systematic and solid testing with data from many distinct scientific areas, and the comparison with the results provided by classical derivatives (it is important to remark that this requires long observation intervals to capture long range memory effects). Furthermore, from a formal point of view, the good or bad fit into data, or the so-called “generalisation” by modifying some kernel, are not necessarily correct in mathematical terms when thinking on the properties of FD. Quoting Henri Poincaré Mathematics has a threefold purpose. It must provide an instrument for the study of nature. But this is not all: it has a philosophical purpose, and, I dare say, an aesthetic purpose. The main aim in this paper is to continue the discussion and try to establish a framework for avoiding misinterpretations and controversial or, even the incorrect, use of definitions.
on this matter have empirically investigated the link between inflation and price dispersion and most of them find a positive relationship. We look at micro data on price dynamics through theperspectiveof dispersion comapring different sellers and focus- ing on the informational aspect of prices and building on the informational consequences of high price dispersion. Rather than focus on which theoretical framework best explains the relative price variability seen on the data, we follow a top-down approach to the infor- mation embedded in prices: we first analyze price setting behavior fromtheperspectiveof economic segments as whole, and then we analyze relative prices fromtheperspectiveof sellers taken individually. Our results suggest that inflation destroys information nec- essary for an efficient resource allocation by making it difficult for the consumer to use this information optimally.
This essay deals with the act of playing fromthe psychoethological perspective and examines the implications of this approach for research and practice regarding a topic that I think is overlooked in the academic field. The term “psychoethological approach” was coined by Walter Hugo de Andrade Cunha – a pioneer of ethology in Brazil (Cunha, 1965, 2004) – and disseminated by those who followed his inspiring proposal (Arcieri, 1995; Ardans, 1996; Ades, 1998; Lencastre, 2010; Lucena & Pedrosa, 2014). Lancastre (2010) points out that psychoethology is the search to conciliate the biological study of behavior with psychological activity. Ades (1986, 1987) believed that psychoethology was an integrated approach to basic behavioral processes, approximating ethology (and behavioral ecology) and experimental psychology, which were developed by means of historically separated paths. This approach has the following programmatic points: 1) selection of ecologically relevant behaviors (functional systems) as an initial focus of analysis; 2) learning as an adaptive phenomenon taking place within functional systems, 3) study of interspecific differences within an ecological reference framework, (4) complementary role of field and laboratory studies, in reciprocal heuristics. Based on this approach, in agreement with Ades (1986, 1987) regarding to its advantages as a generator of research and source of subsidies for a general theory of animal behavior, and inspired by the manifest of Brazilian ethology (Cunha, 1965), I present an invitation-justification for the study of play behavior.
The first agenda, which was hegemonic until the 1980s, deals with corruption fromthe standpoint of modernization theories. It is based on a dichotomous view of society. Such a perspective sees corruption as more prevalent in less- developed societies. The causes of this phenomenon would be related to possible dysfunctions in the political institutions of those societies (Filgueiras, 2008b). This approach to corruption uses patrimonialism as a central concept for understanding the institutional arrangements ofthe societies where this phenomenon is more widespread. In those societies prevails the type of legitimate domination based on “tradition,” according to Weberian categories, and so the social relations would be guided by the confusion between the public and the private, turning corruption into a trivial phenomenon within the relations between state and society (Souza, 2008).
There are several approaches to development and the concept is in constant discussion and revision, as there is no common definition among authors. Debates on development studies vary among economists that associate development with economic growth, with income being measured by gross national product or per capita income (as Lewis, 1954; Myrdal, 1957, Hirschman, 1958; Rostow, 1960), those who argue that dependency and inequality are inherent to capitalist development (as Frank, 1967; Blomström and Hettne, 1984; Kay, 1989). The alternative development ideas, recognizing the social and environmental goals as well as the economic ones (as Nerfin, 1977; Chambers, 1983) and radical critiques “post-development”, which often completely reconstruct the concept of development (e.g., Escobar, 1995; Arnhem and Bawtree, 1997). In this latter stream, the most influential challenge to the mainstream of development came from Capabilities Approachof Amartya Sen (CA), where development is defined as “a process of expanding the real freedoms of individuals” (Sen, 1999, p. 3) to “lead the lives they have reason to value” (Sen, 1999, p. 293).
This study allowed for a comprehensive approach to mosaics known in the city fromtheperspectiveof mosaic art as a technical program associated with resi- dential construction as a whole, but also a renewed look on the ideological ex- pression ofthe decorative programs. These approaches are published here. The study ofthe mosaics of Conimbriga can rely on previous information that allow for its division in two main groups: i) the mosaics ofthe house ofthe foun- tains, published in the respective volume ofthe Corpus dos Mosaicos Romanos de Portugal ; ii) the mosaics kept in situ in other buildings ofthe town. The latter are not systematically studied from a stylistic point of view, which somewhat diminishes the possibility of analyzing them in depth on the irst approach to be made (relating to the activity ofthe workshops) and, on the whole, their mostly geometric character does not allow for deep insights into their ideological ex- pression (the second approach to be made), but this distinction is germane to the very nature ofthe evidence dealt with here, and one has to proceed with it.
A strategic thinker is a mental model ofthe complete systemof value creation from beginning to end, and understands the interdependencies within the chain. The systems perspective helps individuals detect their role within the larger system and the impact of their behavior on other parts ofthesystem, as well as on the outcome. This approach addresses, therefore, not only the fit between the corporate, business, and functional levels of strategy, but also the person’s level. From a vertical perspective, strategic thinkers see the linkages in thesystemfrom multiple perspectives and understand the relationship among the corporate, business, and functional levels of strategies to the external context, as well as to the personal daily choices they make. From a horizontal perspective, they also understand the connections across departments, functions, and between suppliers and buyers.
Grande do sul and is currently teaching at the catholic university of Pelotas. his main research interests include the teaching of reading and writing in l1 and l2 contexts, from an early psycholinguistic approach to a socio-cultural perspective; foreign language teaching policies, as a result of his involvement in many university and national-level committees and representational positions in scientiic associations, including presidency of alaB (applied linguistics association of Brazil) for two terms; computer-mediated learning and distance education, starting with a book chapter on the teaching of concepts in the “atari collection”, published in 1985; research articles on electronic dictionaries, published in the 1990’s; and more recent work on activity heory and complexity, such as the article, “deining a call activity”, published in 2005; and the chapters “call as action” and “authorship in Materials design for language teaching”, both published in 2009.
Objective: To relect upon innovative nursing education based on the epistemology perspectives ofthe South of Boaventura de Souza Santos. Methods: This is a theoretical essay. We used the Southern epistemology by Boaventura de Souza Santos as a reference, highlighting the concepts of decolonization of knowledge, post-abyssal thinking, and ecology of knowledge. Results: The proposal to relect on innovative nursing education fromtheperspectiveof Southern epistemologies is relected in the understanding that de Souza Santos' approach can support the realization ofthe teaching-learning process, which is based on the recognition ofthe plurality of knowledge in sustainable interactions and the dynamics between them without compromising the autonomy of all. Conclusion: There is an emphasis on the fact that it is essential to understand that the technologies for teaching need to integrate a broader educational process resulting fromthe theoretical relections and dialogical skills ofthe nurse as an educator.
ABSTRACT: Mobile computing has become an invaluable and inevitable part of teaching and learning in educational institutions globally. Zimbabwean polytechnics are not spared and those institutions that have chosen to integrate mobile computing with existing teaching and learning applications stand to benefit more than their slow and stagnant counterparts. This paper is investigated whether mobile computing is being used in Zimbabwe Polytechnics. It is based mainly on primary research since no particular research has targeted Polytechnics in Zimbabwe and specifically the Polytechnic understudy in this area, thus a survey was conducted and the survey results were used as the main data source. However, secondary research was incorporated to see what other researchers have found in similar topics the world over. This paper identifies the mobile computing hardware technology, software and communication technologies used at the Polytechnic. It then outlines the achievements made in this area and the associated benefits of such achievements. Finally highlights the challenges currently being faced by the polytechnic in implementing mobile computing and the opportunities the institution can exploit by fully utilizing the technology. The main findings of this research were that Zimbabwe polytechnics in general and the polytechnic in particular have adopted usage of mobile computing to enhance their teaching and learning and administrative activities. There are visible and tangible achievements and benefits that have been realized. Opportunities have been identified which the polytechnic can exploit if it fully embraces mobile computing. However there are some challenges hindering the progress in this regard.
Essence of modification of silumins boils to change of form or size of silicon crystals present as eutectic or primary ones. Perfect sliding properties and high abrasion resistance of hypereutectoid silumins result from their structure, which can be characterized by precipitations of primary crystals of silicon in soft eutectic groundmass. Primary crystals of silicon are unfavorable due to their impact on machinability of material. They bring about considerable wear of tools and have negative effect on conditions of machined surface (big roughness). In case of hypereutectic silumins, by introduction of active nucleuses of crystallization are refined mainly a brittle, hard precipitations of primary silicon . High content o silicon results in necessity of superheating ofthe alloy in limits of 850 – 900 C and keeping it
The examination ofthe structure and microhardness of surface layer of C90 non-alloy steel and HS 6-5-2 high speed steel after electric arc treatment are presented in the paper. The comparison has been presented due to the similar content ofthe carbon in both steels. The structure ofthe remelted zone ofthe steel C90 before the conventional tempering consists ofthe cells, dendritic cells surrounded with the cementite, there is a plate martensite and retained austenite inside them, whereas the structure ofthe steel HS 6-5-2 is consistuted with cells, dendritic cells and dendrites surrounded with the eutectic system, inside of which there is a plate martensite and retained austenite. Such structure is characterized by the similar microhardness (790-800 HV0,065) and intensity ofthe tribiological wear. The tempering causes the decrease ofthe microhardness in non-alloy steel and the increase ofthe microhardness in high speed steel.
Rebonding of sand mix is a common practice in foundry engineering. The sand mix contains used sand whose grains are already coated with the rebonding material. Rebonding ofthe used sand [3,4] involves disintegration of grain agglomerates and uniform distribution ofthe rebodning agent in the entire volume ofthe sand mix batch, coating of sand grains with the rebonding agent and activation of thus formed coating. Turbine (rotor) mixers are now in widespread use as they feature high efficiency and short mixing cycles.
