El ciclo PHVA ha sido utilizado ampliamente para la mejora de los procesos; por ello, es adecuado pensar que es una herramienta útil para la gestión de proyectos. El objeto de la presente investigación es evidenciar los principales aportes que han realizado diferentes autores en la implementación del ciclo PHVA para la mejora continua en la gestión de proyectos. Se realizó una revisión documental, empleando estrategias de búsqueda con palabras clave en Scopus y ScienceDirect. Se recopilaron documentos de los últimos 5 años, resultando un total de 186 artículos. Al verificar la pertinencia con el tema de estudio, la lista se redujo a 21. Se destacan como resultados la vigencia temática del ciclo PHVA, la variabilidad de sectores empresariales y los países que la implementan y estudian. El continente europeo lidera el volumen de publicaciones y a pesar de encontrar alto volumen de artículos, muchos se descartaron por debilidades metodológicas. The PDCA cycle has been widely used for process improvement; therefore, it is appropriate to think that it is a useful tool for project management. The purpose of this research is to show the main contributions that different authors have made in the implementation of the PDCA cycle for continuous improvement in project management. A documentary review was carried out, using search strategies with keywords in Scopus and Science Direct. Documents from the last 5 years were collected, resulting in a total of 186 articles. When verifying the relevance to the subject of study, the list was reduced to 21. The thematic validity of the PDCA cycle, the variability of business sectors and the countries that implement and study it stand out as results. The European continent leads the volume of publications and despite finding a high volume of articles, many were discarded due to methodological weaknesses.

Abstract: The relationship between Le Corbusier and the visual arts (drawing, photography and cinema) is deep and complex and, although the subject of numerous publications and research since the late 60s, still arouses much interest, as evidenced by the many events organized in the last years - "Le Corbusier. Vue sur la mer ", Maison La Roche, Paris, 2012; "Construire the image: Le Corbusier et la Photographie", Musée des Beaux-Arts, the Chaux-de-Fonds, 2013; or the recent "Le Corbusier and photography", IUAV, Venice, May 2015-. The paper, starting out from the researches already developed, proposes a further reflection on the relationship between the Swiss architect and the photography, paying particular interest to the shooting made in first person. The study analyzes the different approaches and the different subjects photographed in the course of his life and it is proposed to include the work of Le Corbusier in the broader cultural context of the twentieth century, a period in which the relationship between architecture and visual communication, thanks to the many possibilities offered by technological innovations, it becomes increasingly close and inevitable. Resumen: La relación entre Le Corbusier y las artes visuales (dibujo, fotografía y cine) es profunda y articulada y, aunque es objeto de numerosas publicaciones y investigaciónes desde el finales de los años 60es, todavía despierta mucho interés, como lo demuestran los diversos eventos realizados en los últimos años - “Le Corbusier. Vue sur la mer”, Maison La Roche, Parìs, 2012; “Construire l’image: Le Corbusier et la photographie”, Musée des Beaux-Arts, la Chaux-de-Fonds, 2013; o la más reciente “Le Corbusier e la fotografia”, IUAV , Venezia, mayo 2015-. El articulo, a partir desde investigación ya desarrollado, propone una reflexión más sobre la relación entre el arquitecto suizo y la fotografía, prestando especial interés a las realizata en primera persona. El estudio analiza los diferentes enfoques y diferentes sujetos fotografiados en el curso de su vida y se propone de insertar la obra de Le Corbusier en el contexto cultural más amplio del siglo XX, un período en el que la relación entre la arquitectura y la comunicación visual, gracias a las muchas posibilidades que ofrecen las innovaciones tecnológicas, se vuelve cada vez más estrecha e inevitable.  Keywords: Le Corbusier; photography; representation of architecture. Palabras clave: Le Corbusier; fotografia; representaciones de la arquitectura. DOI: http://dx.doi.org/10.4995/LC2015.2015.947

This paper investigated cost estimation methods and continuous improvement in terms of project management planning, as well as the factors that influenced these actions. Estimating the cost was one of the most imperative tasks to be done by the managers for a project. Key factors, such as cost, size, schedule, quality, people resources, maintenance costs, and complexity, were usually estimated in the beginning of project development. The techniques used for cost estimation included data composed from past projects that were combined with mathematical formulae to get the closest estimation. In regards to continuous improvement, the four-step quality model (PDCA cycle) was used as an ongoing effort to improve products or services. PDCA stands for plan, do, check, and act, which were the steps to successfully implement change. Notably, project management, when tasked with cost estimation and continuous improvement, was challenged to cope with evolving and situational alterations, which required a different set of skills.

Actually, basic needs postulates securing of the elementary conditions of existence to every human being. Despite of the practical and theoretical importance of the subject the greatest irony is non- availability of any universal preliminary definition of the concept of basic needs. Moreover, this becomes the reason for unpredictability of various political programmes aiming at providing basic needs to the people. The shift is necessary for development of this or any other conception. No labour reforms could be made in history till labours were treated as objects. Its only after they were started being treating as subjects, labour unions were allowed to represent themselves in strategy formulations that labour reforms could become a reality. The present research paper highlights the basic needs of Human Rights in life.

The subject of the research is new tools for business financing using the initial coin offering (ICO) in the context of the development of cryptocurrencies and the blockchain technologies as their basis. The purpose of the work was to analyze the advantages and disadvantages of the ICO in comparison with traditional financial tools as well as prospects, limitations and problems of using digital financial tools. Conclusions are made in relation to possibilities, limitations and application areas of digital business financing tools, particularly in the real sector, taking into account the specifics of the Russian economy and legislation. It is shown that the main problems of using the digital financial tools are related to the economic sphere and caused by the lack of adequate approaches to evaluation of assets as well as the shortage of objective information. The problems and new tasks of corporate finance in the digital economy are defined.

RESUMEN En el artículo se ofrece una reflexión en torno a la educación y valores. Tras una referencia a los diferentes sentidos en que se puede plantear el problema en función de la forma como se puede entender la relación entre los dos sustantivos “educación” y “valores”, la reflexión se centra en algunos problemas relacionados con los valores en cuanto contenidos de la educación. Primeramente se refiere al problema del criterio en función del cual determinar los valores de la educación, concluyendo en que el criterio no podía ser ni de carácter a priori, ni empírico, sino “sintético”. A continuación, se afronta el problema del principio, de la fuente de los valores, o la concreción del criterio de los valores de la educación, entendiendo que éstos deberían ser determinados a partir del sujeto de la educación. Se concluye con la referencia a una exigencia de los valores de la educación, la configuración de una totalidad unitaria e interactiva. Palabras clave: educación, valores, fuente de valores, integración, cultura EDUCATION AND VALUES ABSTRACT The article offers a reflection on education and values. After a reference to the different senses in which one can pose the problem in terms of how you can understand the relationship between the two nouns “education” and “values”, reflection focuses on some problems related to the values in the contents of education. First, it concerns the problem of the criterion against which to determine the values of education, concluding that the criterion could be neither a priori in nature, not empirical, but “synthetic”. Herein, the problem of principle is faced, the source of values, or the realization of the criterion of the values of education, understanding that these should be determined from the subject of education. It concludes with the reference of a requirement of the values in education, setting up a unitary and interactive whole. Key Words: education, values , power values , integration, culture

The book under review is a compilation of the author's articles and lectures that highlight the prominent developments in the literature on the subject of Islamic banking and inform the reader of the current state of debate on it. One of the earliest and main contributors to this topic is the author himself. The focus of this review will mainly be on "Economics of Profit-Sharing", which is the title of the fourth chapter of the book and is among his latest contributions. This chapter is a significant contribution as it is the first attempt to formalise the concept of profit sharing into an analytical model and, therefore, demands closer scrutiny. However, in the remaining chapters of the book, the author has drawn attention to some of the fine points made in the literature on this topic. Since some of these points appear to be controversial to me, I will briefly discuss them before moving on to the analytical chapter of the book.

O artigo tem por objeto o exame de três registros de gritantes e distintos paradoxos na Doutrina do Direito de Kant. Registros feitos em tempos e contextos históricos diferentes por Friedrich Bouterwek, Marcus Willaschek e Balthazar Barbosa Filho. Bouterwek atribuiu a Kant a mais paradoxal das proposições jamais enunciadas por qualquer autor, a de que a mera ideia de soberania deve obrigar-nos a obedecer como a nosso inquestionável senhor a quem quer que se haja estabelecido como tal, sem que caiba indagar quem lhe deu o direito de comandar-nos. Willaschek aponta a incompatibilidade de duas teses centrais da doutrina kantiana: a do caráter externo dos vínculos jurídicos e a da incondicionalidade obrigacional do direito positivo, pois não é possível entender como é possível termo-nos como obrigados por imperativos jurídicos e, ao mesmo, vermo-nos internamente isentados do dever de obedecê-los. O ponto crítico de Balthazar é alegar que não pode haver na filosofia kantiana uma crítica da razão político e jurídica, simplesmente porque o conceito de imputação, base da normatividade própria dessas esferas, pressupõe uma pluralidade de agentes livres que, justamente, só pode ser uma pressuposição, pois nosso acesso à normatividade prática só pode ter lugar em primeira pessoa. No exame a que o artigo submete essas alegações, o artigo argumenta, em objeção à tese de Balthazar, que o caráter universal e categórico da força que vincula o sujeito quando confrontado com a lei moral em primeira pessoa necessariamente se desvaneceria se, ao mesmo tempo, ele não fosse tomado pela evidência de que a realidade objetiva dos princípios morais é não só instanciável, mas assegurada pela múltipla instanciação. Com relação às dificuldades levantadas por Willaschek e Bouterwek, o artigo argumenta que o princípio exeundum e statu naturali, enquanto norma metapositiva, anterior à divisão do domínio prático entre doutrina do direito e doutrina da virtude, permite ao mesmo tempo compreender a exigência de obediência ao poder constituído e a restrição das obrigações jurídico-políticas exclusivamente ao foro externo.AbstractThe object of the article is to examine three claims about three distinct and allegedly blatant paradoxes in Kant's Doctrine of Right. These three critical points had been made in distinct times and contexts by Friedrich Bouterwek, Marcus Willaschek e Balthazar Barbosa Filho. Bouterwek attributed to Kant the most paradoxical of all paradoxical propositions, the statement that by the mere idea of sovereignty we are obliged to obey as our lord who has imposed himself upon us, without questioning from where he got such right. Willaschek points out the incompatibility of two main theses of Kantian doctrine of right: the claims that the legal bounds are of external character and that they are the source of unconditional obligations, since it seems impossible to understand how it would be possible to be obliged by juridical norms and decisions and at the same time to be exempted of the internal duty of compliance. The radical objection of Professor Balthazar is the claim that in the context of Kantian Philosophy it is impossible to admit a critique of the juridical and political reason because the concept of imputation, ground of the normativity in these domains, requires not only the presupposition of free agents, but a true and secure epistemic access to them, which is, according to him, impossible considering that the moral law and the other practical principles are accessible for us only in the first person. In the course of the appraisal of such claims, the article contest that objection arguing that the universal and categorical force of the normative bound experienced by the subject when confronted with the moral law in the first person would ineluctably vanish if, at the same time, he had not been taken by the evidence that the objective reality of the moral principles is secured by multiple instancing. Regarding the difficulties raised by Willaschek and Bouterwek, the article argues that the principle exeundum e statu naturali, as a norm of meta-positive character, prior to the division of practical domains between the doctrine of right and the doctrine of virtue, is the cue both to the understanding of the requirement of unquestioning obedience to the constituted power and to the restriction of the validity of this requirement only in foro externo.

This chapter examines the socio-economic motivations behind the shaping of retail landscapes in Roman cities. It is about who opened retail outlets, as well as why and where. After critiquing some of the normal methods for illustrating the locations of shops and bars, including the conventional distribution plan itself, as well as questioning the economic rationality of operating tabernae, this chapter argues for the value in complicating our otherwise basic understanding of why urban investments were made in the places we find them. Rather than accepting profit as the single motivation to urban investment, a range of social, economic, and political motivations are considered as an explanation for the ultimate shape of Roman retail landscapes. Thus beyond discussions of space and urban topography, the subject of this chapter is investment.

Sometimes, it is impossible to conduct tests with the use of the GNSS system, or the obtained results of the measurements made differ significantly from the predicted accuracy. The most common cause of the problems (external factors, faulty results) are interference disturbances from other radio telecommunication systems. The subject of this paper is to conduct research, the essence of which is an in-depth analysis in the field of elimination of LTE interference signals of the GNSS receiver, that is based on the developed effective methods on counteracting the phenomenon of interference signals coming from this system and transmitted on the same frequency. Interference signals are signals transmitted in the GNSS operating band, and unwanted signals may cause incorrect processing of the information provided to the end-user about his position, speed, and current time. This article presents methods of identifying and detecting interference signals, with particular emphasis on methods based on spatial processing of signals transmitted by the LTE system. A comparative analysis of the methods of detecting an unwanted signal was made in terms of their effectiveness and complexity of their implementation. Moreover, the concept of a new comprehensive anti-interference solution was proposed. It includes, among others, information on the various stages of GNSS signal processing in the proposed system, in relation to the algorithms used in traditional GNSS receivers. The final part of the article presents the obtained research results and the resulting significant observations and practical conclusions.

Introduction In order to promote training and education in special-needs dentistry an attempt was made to introduce problem-based learning (PBL) as a method of postgraduate dental education. The aim of this paper was to review the principles of PBL and report on a case study using this methodology. Method The case study was of a PBL session, on the subject of ‘problems of obtaining appropriate dental care for people with epilepsy’, undertaken at a national conference. Delegates were asked to complete a pre- and post-session questionnaire on PBL and their attitudes to the session. Results The session received a mixed response. Only 33 (35%) thought the session was valuable and only 20 (31%) thought it was better than conventional teaching methods and yet over half (55%) said they would like to attend more PBL in special-needs dentistry. Professionals complementary to dentistry were more likely to find the PBL session of value and to prefer the method to a more conventional format than dentists were (chi-square=5.5, df=1, p<0.05 and chi-square=5.9, df=1, p<0.05 respectively). Conclusion Valuable feedback was received from delegates. This will enable improvements to be made in future courses so that the effectiveness of PBL can be optimised.
