La facilidad de acceso a la tecnología ha propiciado la llegada de una nueva revolución industrial que capacita a los ciudadanos para dejar de ser meros usuarios y convertirse en creadores y constructores de sus propios bienes, apoyándose en las tendencias sociales basadas en la cultura colaborativa. El surgimiento de los Fablab -Fabrication Laboratory- como entornos que potencian dichas capacidades en los usuarios ha sido decisiva en esta democratización tecnológica, y sigue un ritmo creciente incesante, extendiéndose de forma llamativa por todo el planeta. A través de siete etapas, descritas en este artículo, se presenta el proceso de construcción y validación de la herramienta de obtención de información denominada FabLab Global Survey con el objetivo de conocer y caracteriza el fenómeno FabLab. La falta de referentes teóricos y la limitada bibliografía académica sobre el tema hace necesario el diseño de dicha herramienta basándonos en aportaciones de los expertos en el fenómeno FabLab y, para ello, se consideró adecuada su validación mediante el método Delphi, ya que permite la transmisión de la información subjetiva aportada por los expertos, respetando sus peculiaridades. El reto al que nos enfrentamos como investigadores estriba en nuestra capacidad de transformar los resultados obtenidos para su valoración a través de herramientas analíticas cuantitativas. Para compensar y equilibrar la subjetividad de las opiniones expresadas por el panel de expertos mediante escalas nominales, se emplea el Modelo de Torgerson, que permite un reescalamiento de la escala original cualitativa en una escala de intervalo (cuantitativa) verificando la equivalencia entre ellas. Asimismo, y una vez contrastada la adecuación de la escala utilizada, se realiza un análisis cuantitativo y cualitativo de las aportaciones generadas por el grupo de expertos que permiten perfilar las características del cuestionario resultante. La excelente acogida de la Fablab Global Survey obtenida durante la distribución entre los gestores de los FabLabs -que señalan su idoneidad y acierto en la selección de cuestiones planteadas- muestra la adecuación del método Delphi para la generación de herramientas de investigación que permitan, como es el caso que nos ocupa, abrir nuevas líneas de investigación.The ease of access to technology has led to the arrival of a new industrial revolution that enables citizens to stop being mere users and become creators and builders of their own assets, relying on social trends based on collaborative culture. The emergence of the Fablab -Fabrication Laboratory- as environments that enhance these capacities in the users has been decisive in this technological democratization, and continues in an incessant rhythm, extending by the whole planet. Through seven stages, we describe in this article, the process of construction and validation of the information retrieval tool called FabLab Global Survey, with the objective of characterizing the FabLab phenomenon. The lack of theoretical references and the limited academic literature on the subject makes necessary to design such a tool based on contributions from the experts in the FabLab phenomenon and, for this purpose, it was considered appropriate to validate it using the Delphi method, since it allows the transmission of the subjective information provided by the experts, respecting their peculiarities. The challenge we face as researchers lies in our ability to transform the results obtained for their valuation through quantitative analytical tools. To compensate and balance the subjectivity of the opinions expressed by the panel of experts using nominal scales, the Torgerson`s Model is used, which allows a rescaling of the original qualitative scale on an interval scale (quantitative) by verifying the equivalence between them. Likewise, and once the adequacy of the scale used is verified, a quantitative and qualitative analysis of the contributions generated by the group of experts is carried out, allowing to profile the characteristics of the resulting questionnaire. The excellent reception of the Fablab Global Survey obtained during the distribution among the managers of the FabLabs - which point out their suitability of the questions - shows the appropriateness of the Delphi method for the generation of research tools that allow, as it is the case in hand, open new lines of research.

It has been estimated that graphology is used by over 80% of European companies as part of their personnel recruitment process. And yet, after over three decades of research into the validity of graphology as a means of assessing personality, we are left with a legacy of equivocal results. For every experiment that has provided evidence to show that graphologists are able to identify personality traits from features of handwriting, there are just as many to show that, under rigorously controlled conditions, graphologists perform no better than chance expectations. In light of this confusion, this paper takes a different approach to the subject by focusing on the rationale and modus operandi of graphology. When we take a closer look at the academic literature, we note that there is no discussion of the actual rules by which graphologists make their assessments of personality from handwriting samples. Examination of these rules reveals a practice founded upon analogy, symbolism, and metaphor in the absence of empirical studies that have established the associations between particular features of handwriting and personality traits proposed by graphologists. These rules guide both popular graphology and that practiced by professional graphologists in personnel selection.

Introduction. Based on modern social trends, the demand becomes not only for professionally trained people, but also for the level of their general culture, value system and, ultimately, intelligence. At the same time, there is no place for intellectuals and educating intellectuals in program documents on educational activities, although this task is very logical for the pedagogical practice of a developed society. This work presents the experience of the author's analysis of the psychological nature of the intelligence of an officer. Consistently considering the essence and structure of such a complex phenomenon, the structure and the real functioning of the values that allow characterizing the subject as an intellectual are ascertained.Materials and methods. As the main research methodology, the authors use sociological (I.S. Kon), culturological adapted to solve the problems of this work (M.S. Kagan), historiographic (A.V. Popov), systemic (I.V. Blauberg, V.A. Lektersky, V.N. Sadovsky, S.L. Rubinstein, M.S. Kagan, N.V. Kuzmina) and functional approaches (P.K. Anokhin, M.S. Kagan, N. Wiener). The main research methods were: hypothetical-deductive method; analysis, synthesis, comparison, analogy and abstraction; systemic method and modeling.Results. The result of the study is that the authors identified and justified the structural psychological qualities of intelligence as the subjective characteristics of an officer and examined the basic mechanisms of formation of intellectual values.Discussion and Conclusions. The required criteria for being intelligent as a  subject characteristics of an officer is the level of education (self education)of an officer, his manners, the scope of his values , existential assessment –correlating every fact he faces with general life-span problems of objective reality, having respect for values of others and being ready for talk to employees and  superiors as well as the representatives of other social groups, other cultures, nationalities, confessions and professions which requires dialog in search of optimal forms and options of interaction. The cornerstone principle for intelligence of the officer are, therefore, his education and upbringing, ideological conviction in his own values and readiness for self-sacrifice for their sake.

Laws governing adolescent sexuality are incoherent and chaotically enforced, and legal scholarship on the subject neither addresses nor remedies adolescents’ vulnerability in sexual encounters. To posit a meaningful relationship between the criminal law and adolescent sexual encounters, one must examine what we know about adolescent sexuality from both the academic literature and the adults who control the criminal justice response to such interactions. This article presents an in-depth study of In re John Z., a 2003 rape prosecution involving two seventeen-year-olds. Using this case, I explore the implications of the prosecution by interviewing a variety of experts and analyzing the contemporary literature on sexual norms among youth. I also relate a series of interviews conducted with the major players in the prosecution. Examining this case from a variety of perspectives permits a deeper understanding of how the law regulates adolescent sexual encounters and why it fails.

There exists a consensus in academic literature regarding the centrality of engraved prototypes for the production of colonial paintings in the Spanish Americas. In Peru, these artistic models were written into legal contracts between painters and clients. An examination of the notarial contracts produced in Cusco from 1650 to 1700 suggests that prototypes in a variety of formats were not only central to artistic professional practice, but that adherence to their images may have provided one motive for entering into such agreements. This study leans upon the centrality of Flemish print sources to confirm the attribution of a partial canvas at the Pinacoteca Universidad de Concepción, Chile as an episode of the series on the life of Diego de Alcalá (c. 1710) in Santiago, Chile. Commissioned from Cusco by the Franciscans of Santiago, the status of the hagiographic cycle as the most extensive ever produced on the subject of this missionary saint dictates that a multiplicity of sources was necessary for its creation. By identifying two engravings that served as its models, this study recovers the subject of this painting as a miracle that sustained Diego during an arduous journey.

At a time when the Republican party in America seems to have abandoned its brief hopes of proclaiming a new paradigm, it may seem apropos to observe that old ones die hard—and not only in public life. A case in point from the scholarly world is the subject of this essay: the persistent historiographical notion of industrial factionalism. Throughout this century, students of German political economy have tended to see the country's business world as divided between two groupings. One comprises the classic heavy industries of the first Industrial Revolution and the Ruhr: coal, iron, and steel. Supposedly oriented toward domestic markets, burdened with high labor costs, doomed to flattening gains in productivity and profits, and habituated to hierarchy within their plants and the nation, executives in this grouping have figured in the historical literature as consistently and intransigently united against free trade, labor unions, and parliamentary government—indeed, against modernization itself.

Purpose In recent years, cities have been facing economic, social and environmental crises that need to be prevented and dealt with. The new subject that has been brought up to improve city resistance to crises is urban resilience. The purpose of this study is to compare the resilience of Tehran and Mashhad to identify the strengths and weaknesses of these two cities for better planning in critical situations. Design/methodology/approach The research methodology is a comparative survey. The importance of the subject was manifested through a literature review. A questionnaire is designed using “the Rockefeller Foundation and ARUP’s model” and the Delphi method for testing 21 research hypotheses to evaluate resilience in the two cities (12 Delphi questionnaires and 232 urban resilience questionnaires). The data is analyzed using independent samples t-test by SPSS software. Findings The results show that both the cities are weak in terms of resilience indicators and sub-indicators, but Mashhad is more resilient than Tehran. Originality/value This paper compares urban resilience in Iran for the first time through a comparative study between two metropolises in the country. The Delphi method also is used for the first time (in Iranian case studies) to obtain the dimensions of urban resilience. By comparing the two cities, we can better understand their strengths and weaknesses.

Purpose This study aims to analyse how the materials selection courses of engineering undergraduate programmes can be better aligned with the United Nations Sustainable Development Goals (SDGs). Design/methodology/approach Initially, a content analysis was performed in 39 materials selection course descriptions from 40 engineering undergraduate programmes of Brazilian higher education institutions, and subsequently, Delphi method procedures were conducted with professors that teach or have taught the course and are knowledgeable in the subject of sustainability. Findings Considering the analysed course descriptions, it was shown that most of the materials selection courses do not consider or present little emphasis on sustainability aspects. Regarding the Delphi method, eight items were evidenced to consider sustainability aspects in the analysed courses. Originality/value This study contributes to the debates about sustainability insertion in engineering undergraduate programmes. More specifically, the findings presented consolidated information that professors and coordinators can use to align materials selection courses with the SDGs better.

Industry 4.0 (or 4<sup>th</sup> industrial revolution) facilitates horizontal and vertical digital information flow along value chains up to the end-customer and is highly relevant in a broad variety of industries. Augmented reality (AR) is a key technology in Industry 4.0, which connects the virtual and real-world environments using such digital information flows. In doing so, the technology relies upon the systems that includes hardware and software components. Particularly, optics and photonics are of much importance in the display and processing of information in these systems. However, a particular challenge is that the AR-based systems have not been adopted in the industry as much as other technologies even after several decades of their existence. Based on review of academic literature, an industrial survey and experiments conducted in the industry, this article aims to identify success factors and challenges of AR systems and metrics of photonic components that can form the basis of an AR* framework for photonics-based system design for future research. @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:3 0 0 0 1 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman",serif; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:EN-US; mso-fareast-language:EN-US;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt; mso-ansi-language:EN-US; mso-fareast-language:EN-US;}div.WordSection1 {page:WordSection1;}

Today one of the biggest expense items of the enterprises is raw material and stock amounts. Therefore, proper inventory management is very important for the profitability of the enterprises. Products that are not purchased on time cause interruptions in production and products left over because the expiration date has passed will also cause losses for businesses. Therefore, proper inventory management is critical for profit / loss situations of businesses. In this paper we presented a model to predict the demand of certain stock items by using a regression model. Our model can analysis and computer the prediction results on agiven dataset. We evaluate our model on sample dataset and provide the analysis as well calculations over the existing inventory. Accurate analysis of stock consumption enables accurate estimation of the amount of stock to be consumed in the future. Accurate forecasting of stock consumption helps to take corrective steps in decision making. That is, it only allows you to buy in sufficient quantity when necessary. These stages are critical for economic stock management. For this reason, robust and adaptable approaches that can provide models ensure that stock consumption can be managed properly. It is difficult to find previously written sources on estimating the direction of stock movements. One of the most important reasons for this is the lack of incentive to make such studies in the academic literature. As a result, articles written about the subject and the work done have been limited, the results have not reached the reproducible level.
