This chapter provides an overview and guide to the methodology, theory, practice, and ethics of ethnographic filmmaking. Examining in turn the various uses of film in anthropology, the differences between anthropological writing and anthropological films, and the kinds of knowledge produced by each, it proceeds to discuss the practical concerns of the anthropological filmmaker: questions of point-of-view, method, and different approaches to the construction of films. It considers the pros and cons of teamwork and single-author filmmaking, aspects of film aesthetics, relationships with the subjects of films, the filmmaker’s behaviour in the field, and different modes of camera use. Finally, it addresses the different practical strategies possible for this kind of filmmaking, including a focus on individuals as subjects, the uses of narrative, and thematic approaches. Also considered is the filmmaker’s relation to the viewer, and ways of making the filmmaker’s intentions and practice more evident within the film.

There are many thousands of existing pony truss bridges in North America which were constructed in the earlier part of this century and are still serving as important traffic carriers. The present economic situation demands that these bridges should usefully serve their purpose for as long as is safely possible.These bridges could be found inadequate for either or both of the following reasons. With the exception of remote areas, operational traffic safety would require two 12-ft lanes plus adequate shoulders. Many of these old bridges are therefore unsatisfactory from the geometrical point of view. Some bridges were designed for live loads that are only a fraction of present commercial vehicle weights.A computer-oriented method of rigorous analysis of lateral buckling behaviour of pony truss bridges is briefly discussed. The method is implemented through a computer program which has been validated by experimental data. It is expected that the program would predict realistic values of load-carrying capacity of such bridges and would help to avoid many an unnecessary replacement.Various methods of strengthening and widening pony truss bridges, and their pros and cons, are discussed. It is shown that the strengthening of a few components of a pony truss bridge does not always lead to an increase in the load-carrying capacity of the bridge.

This chapter presents a set of scenarios involving the GoPro wearable Point of View (PoV) camera. The scenarios are meant to stimulate discussion about acceptable usage contexts with a focus on security and privacy. The chapter provides a wide array of examples of how overt wearable technologies are perceived and how they might/might not be welcomed into society. While the scenario is based at the University of Wollongong campus in Australia, the main implications derived from the fictitious events are useful in drawing out the predicted pros and cons of the technology. The scenarios are interpreted and the main thematic issues are drawn out and discussed. An in depth analysis takes place around the social implications, the moral and ethical problems associated with such technology, and possible future developments with respect to wearable devices.

Although Canada has been blessed with an abundant store house of natural resources and enjoys a significant measure of economic and political influence throughout the world, she has a relatively small and widely scattered population. The Canadian economy is largely based on resource industries of which those producing forest products are outstanding, and the very economic existence of Canada is dependent upon her ability to export goods and services.Some of the more critical export problem areas include non-resident ownership, the wage-cost spiral, the loss of traditional markets in forest products and finally the problems associated with researching markets in foreign countries.A matter of concern to many is the lack of investment in Canada's forests although the forest resource is capable of sustaining several times present production. Most disturbed lands regenerate naturally, but not necessarily in the desired species. The questions to be asked by management foresters are: (1) should we concentrate on the production of wood fibre or, (2) should we stress the growing of known species of superior quality? The pros and cons of each of these widely divergent forest policies are easily argued.Lack of an internal market is incurable over the short term; but Canada's immigration policies, her participation in trade conferences, agreements and international organizations, and her attempts at economic diversification all help to alleviate problems associated with her dependency on foreign markets.The results of these actions coupled with a trend toward equalization between forest growth and utilization will provide the necessity and incentive for a stepped up forest investment program in Canada.

This chapter presents the ISO/IEC MPEG-7 Multimedia Content description Interface Standard from the point of view of managing semantics in the context of multimedia applications. We describe the organisation and structure of the MPEG-7 Multimedia Description schemes which are metadata structures for describing and annotating multimedia content at several levels of granularity and abstraction. As we look at MPEG-7 semantic descriptions, we realise they provide a rich framework for static descriptions of content semantics. As content semantics evolves with interaction, the human user will have to compensate for the absence of detailed semantics that cannot be specified in advance. We explore the practical aspects of using these descriptions in the context of different applications and present some pros and cons from the point of view of managing multimedia semantics.

Given the exponentially expanding water pollution causing water scarcity, there is an urgent need for operative nanotechnological systems that can purify water, with insignificant energy consumption, and rapidly. Here, we introduce a nanocomposite system based on TiO2 nanoparticles (NPs) and PES nanofibers (NFs) that can adsorb and then photodecompose organic water pollutants such as dye molecules. We evaluate pros and cons of this system with respect to its purification efficiency and structural properties that can be impacted by the photocatalytic activity of the nanofillers. While the material is superhydrophilic and able to remove 95% methylene blue (MB) from water via adsorption/photodecomposition, its thermomechanical properties decline upon UV irradiation. However, these properties still remain at the level of the neat NFs. The removal behavior is modeled by the first- and second-order kinetic models from the kinetic point of view. The nanocomposite NFs’ removal behavior complies much better with the second-order kinetic model. Overall, such feedbacks implied that the nanocomposite can be effectively applied for water treatment and the structural properties are still as reliable as those of the neat counterpart.

This article analyzes two of the last innovative financing instruments of the crowdfunding family: Initial Coin Offering (ICO) and Initial Exchange Offering (IEO). Having both a potential financial nature, they will be addressed as «sons» of Equity-based Crowdfunding (EBCF). The main scope of this paper is to show opportunities and dangers of ICO and IEO through a comparison with EBCF. Indeed, at the end of the analysis it will be possible to understand if ICO and IEO can be considered as positive evolution of EBCF or — at least one of them — can be considered so dangerous to appear as a sort of «involution».In order to answer our question, the discussion firstly focuses on EBCF, the innovative financing instrument being one of the most important figures of the «crowdfunding family». Its importance lies in its financial nature that makes this instrument different from the other models (meaning the donation, reward and lending). Participating in an EBCF-campaign, indeed, lets participants become shareholders of the company they are giving money to. So, the main pros and cons of the participation in an EBCF campaign will be disclosed. In particular, granting easier access to capitals together with the possibility to benefit from the so-called «wisdom of the crowd» allowed EBCF to become one of the most innovative financing tools of our age. However, these advantages need to be mitigated with the main risks occurring during a crowdfunding campaign. These are: moral hazard and frauds, arbitrary exclusion during pre-emptive screening by platform and, last but not least, illiquidity.Therefore, the discussion moves to the technological advanced new entry of the crowdfunding family, meaning ICO and IEO. In order to understand why ICO and IEO are so similar to EBCF, both the main characteristic of these instruments will be described. With reference to ICO, first of all this article provides a brief description of the technology that makes this innovative financing tool the advanced «son» of EBCF. Indeed, through the launch of an ICO, a company asks the crowd a precise amount of money in exchange of a «token»: an informatic instrument through which the participant may exercise also some financial rights towards the company. From this point of view, an ICO-campaign is very similar to an EBCF one, lying the main difference in the technological solutions used, the queen on those is blockchain. Furthermore, ICO characteristic will be outlined in order to disclose its functioning — meaning the relation with blockchain and smart contracts — and the different models of tokens.After that, also IEO will be described. IEO could be considered one of the last variants of ICO. The main difference, indeed, lies in the fact that IEO campaigns are not conducted in the website owned by the company but in a specific platform, that is a crypto-asset exchange.The exam of ICO and IEO potentialities (i.e. programmability, disintermediation and tokenization) will highlight how ICO and IEO may solve most of the mentioned EBCF cons. This will lead to the potential consideration of ICO and IEO as evolution of EBCF. However, also ICO and IEO cons will be highlighted (meaning lack of transparency, not clear regulatory regime and, for IEO in particular, dangerous proximity with investors and potential conflict of interest). From the comparison between ICO and IEO pros and cons it will be possible to discuss on if we are really in front of two evolution of EBCF or nearer to an «involution» of this instrument, considering regulatory solutions in order to avoid this second scenario.

This article is aimed at identifying the peculiarities of students' attitude to distance education. As a leading method, the questionnaire method was used, which made it possible to identify the students’ positive and negative attitudes regarding distance learning more effectively. The article considers students' ideas about distance learning, identifies the positive and negative aspects of the distance learning process. The authors of the article in the process of research revealed that many students of various fields of study are interested in participating in distance courses, but within the framework of mastering a second education. Some students note the usefulness of distance courses, the use of their materials at any time, and the convenience of going back to the materials they have completed at any time to fill in gaps or recall a topic. Some students reported a violation of the educational process in the distance format due to the repeated lack of Internet or its poor quality. Most of the students expressed dissatisfaction with the lack of contact communication in the distance learning process. It is proved that the majority of students believe that distance education will never replace traditional education. Mainly students of technical areas of study gave a negative assessment of the distance education system. It was revealed that students of various fields of study took distance courses that were held in other cities or countries. From the point of view of many students, educational websites have an inconvenient interface.    Keywords: distance education, distance courses, students, learning process, pros and cons.

Abstract Degradation of the environment is nowadays believed to be the most alarming problem that needs to be solved. Global warming and environmental pollution are predicted to cause a catastrophic chain reaction leading to species extinction, mass emigration due to rising sea levels and global crisis. The only solution suggested by international organizations is the immediate reduction of greenhouse gases and other harmful substances. Marine transportation harmful substances into the atmosphere are recognized to be a significant source of global atmospheric pollution. Despite the high efficiency of marine diesel engines, their impact on the environment is considerable. Due to environmentally friendly policies, modern engines concerns about not only efficiency but also mainly about s aspects. This article analyses and compares marine s exhaust gases reduction methods. Especially the most harmful substances emitted by ships were taken into consideration. The article presents the most crucial law regulations of harmful substances to the atmosphere, pointing at actual and possible future implementations. The most complex methods allowing meeting the latest limits were presented. Pros and cons of available control methods were thoroughly described and methods were compared. The most adequate methods form the effectiveness and economical point of view was pointed out.

The Banking system in India and all over the world is based on the interest system. Interest bearing money is almost like the law of nature where money generates money. However, an alternative banking system called Islamic banking which prohibits charging of interest and is based on profit/loss sharing system became popular in many countries. Global Islamic banking assets attained compounded annual growth rate (CAGR) of around 17% from 2009 to 2013 according to the World Islamic Banking Competitiveness Report 2014-2015. The Indian Banking system has undergone many changes in the recent past with deregulation of banking system paving way for new banks in India. However, Islamic banking which has emerged as a global phenomenon lately has not evolved as a full-fledged system in India though is it operative through the NBFC route. The research paper tries to explain the concept of Islamic banking and discusses the various financial products offered by the Islamic banks. It weighs the various pros and cons of Islamic banking in India. SWOT analysis and Porter’s Five Forces Model are used to provide a thorough analysis of feasibility and scope of Islamic banking in India. The paper reveals that India has a great potential for Islamic banking provided necessary changes in the regulations and guidelines are made to evolve it has an alternative system of banking. The law makers should view it from  an economic point of view rather than a religious view for its successful implementation and  for the welfare and upliftment of financially excluded sections of society that do not participate in conventional banking due to their religious beliefs.

<p>Measurand MEMS ShapeAccelArray sensors are in many ways unique and new equipment, which allows to determine the relative displacements and deformations in other ways than before. The instruments are described, tested and compared with existing instrumentation in a small number of articles, but with exception of one it was not tested from engineering surveying point of view, where the exact precision and accuracy knowledge is a basis for the further use. The result of the experiments is the accuracy of measuring changes by the sensor itself, the pros and cons of its use and some features of its design, which is good to know before using it.</p><p>There were designed and performed practical tests to determine the relative and absolute measurement accuracy of the sensor deformations measurement in all three possible types of use, namely the vertical installation, the horizontal installation and the measurement of convergence.</p><p>The results show high accuracy of the sensor tested, which is under certain conditions even considerably higher than that given by Measurand</p>
