Taxation and Investment Decisions in Petroleum
Authors: Davis Graham A. , Lund Diderik
Published: December 2018

When governments apply high tax rates targeted at natural resource rent, there must be generous deductions in order to avoid investment disincentives. How generous is disputed. Based on standard finance theory and recommendations from the OECD and the IMF, the value that firms attach to future deductions depends on the risks of these, and the companies’ after-tax weighted-average cost of capital cannot be applied directly. As an example, a simple model quantifies the difference between pre-tax and post-tax systematic risk when tax deductions are less risky than pre-tax cash flows. Osmundsen et al. (2015) suggest that the difference must be ignored by oil companies, since they cannot find the separate market values of tax deductions. But companies operating in different jurisdictions cannot then appreciate differences in tax systems, not even approximately, which will lead to suboptimal decisions. Tax designers may instead assume that companies have gradually adopted more sophisticated methods of investment decision making.
Antidumping and Feed-In Tariffs as Good Buddies? Modeling the EU-China Solar Panel Dispute
Authors: Bougette Patrice , Charlier Christophe
Published: December 2018

The paper analyzes the interactions between trade and renewable energy policies based on the EU-China solar panel dispute which is the most significant antidumping (AD) complaint in Europe. We build a price competition duopoly model with differentiated products and intra-industry trade in photovoltaic (PV) equipment. We show that an optimal antidumping duty always increases with the feed-in tariff (FIT) program set in the home country. An appropriate antidumping duty—nullifying the dumping margin—decreases with the FIT program. We show that optimal FIT increases with the AD duty. Therefore, trade and renewable energy optimal policies may complement one another. Lastly, we introduce R&D activities in the PV sector, and international spillovers. We show that R&D makes the optimal FIT lower and increases the dumping margin. These effects are reinforced by technological spillovers.
Competiveness of Medical Tourism Offers and Government Policy
Authors: Dziedzic Ewa
Published: December 2018

Purpose. Identification of the role of government in the development of competitive medical tourism offers. Method. This is exploratory research, employing the grounded theory method that is characterized by an inductive approach to the analysed issue. Findings. Governments of the most competitive medical tourism destinations relatively rarely take on the role of service producers or developers. More often, they assume the role of service regulators, especially in the area concerning the quality of services and conditions for development of medical tourism. The scope and particular methods of intervention differ but it can be hypothesized that there are two basic models: in the first one, the private sector is a catalyst of development while the government takes on the role of a co-ordinator at the most advanced phase, in the second one, the government initiates and leads the development since its early stages. Research and conclusions limitations. The research has been based on secondary sources and covers selected cases in the particular period that may affect the generalization of the outcomes. Practical implications. The research provides some guidelines concerning the involvement of government and the instruments to deliver competitive medical tourism offers. Originality. The research makes an original attempt to identify governments’ activities in the area of medical tourism and provides a documented elaboration on Porter’s concept of competitiveness for the 10 top, most competitive destinations. The purpose and number of cases that were examined differ the research from similar attempts more limited in their scope. Type of paper. Empirical research on 10 cases.
Families with Children as Consumers on the Tourism Market – Research Challenges
Authors: Delekta Anna , Kurek Sławomir , Mróz Franciszek , Rettinger Renata , Ziółkowska-Weiss Kamila , Żemła Michał
Published: December 2018

Purpose. The aim of the paper is to point to the most important research areas within our scientific knowledge regarding the group-nature of the consumer on the tourism market, whose role is very often played by families. Method. The paper is a review and discussion and the most important research methods used are critical literature review and inductive reasoning. Findings. The most important issues which need intensive scientific research are: diversification of consumer behaviour of families belonging to different types, including patchworking families becoming more and more popular; the impact of demographical changes on families’ consumer behaviour in big cities; roles of particular family members in decision processes in light of changing demographic conditions. Research and conclusions limitations. The paper presents the state of scientific knowledge valid for the beginning of 2018 and the scientific gaps described in the paper will probably be bridged successively by prochain publications. Practical implications. This paper dealing with scientific knowledge does not offer readymade solutions for the tourism business, however, the topic of families as consumers on the tourism market itself should be interesting for the widely understood tourism industry as a whole. Originality. Contemporary works dealing with families on the tourism market are rather concentrated on solving particular, detailed problems and not complex and wide scope diagnosis of the state of affairs have been published so far. Type of paper. Review and discussion paper.
Circular Economy in The Opinions of Small- and Medium-sized Hotel Enterprises
Authors: Kachniewska Magdalena
Published: December 2018

Purpose. Assessment of the degree of preparation of Polish entrepreneurs in the hotel sector to implement the principles of circular economy and recognition of their opinions in the field of formal and economic conditions for the creation of a circular economy in Poland. Method. The views presented in this article are the result of a review of literature on circular economy and empirical studies carried out using the monographic method based on a survey and structured IDI (individual in-depth interview) among a group of 64 hotel enterprises. Findings. The study assessed 5 basic areas characteristic for circular economy. In the course of the interviews, it was established that the areas most poorly prepared to implement the principles of circular economy in the group of hotel SMEs are the design, consumption and use (in particular re-use and repairs). The assessment of preparation in the areas of raw material collection and distribution was slightly better. The knowledge of circular economy issues among investors and designers, attitudes and consumer awareness, state of legal regulations and availability of support from public authorities (in the area of education and financing solutions in the field of circular economy) were rated as low. Research and conclusions limitations. The results of research carried out using the monographic method, based on subjective assessments of respondents, should be treated with caution and do not allow to draw general conclusions. They are, however, an indication for future activities concerning the education of entrepreneurs and consumers in the field of circular economy assumptions and setting research and development priorities aimed at strengthening the closed circuit in the economy. Practical implications. The conclusions and postulates formulated by the respondents point to the insufficient preparation of the economy for the implementation of the circular economy principles and the need to take action in the area of education, legal regulations and fiscal policy. In the opinion of hotel entrepreneurs, without changes at the general economic and formal- legal levels, the actual implementation of circular economy principles in the hotel industry will not be possible due to the complex system of investor and operator relations with suppliers and subcontractors. At the most, individual actions may be limited to assumptions of social responsibility and sustainable development formulated for years, which cannot be equated with a closed circuit. Originality. This is the first survey of tourist entrepreneurs' opinions on the possibilities of implementing a circular economy and their readiness to meet the requirements of the circular economy. Type of paper. An article presenting the results of desk and empirical research.
The Jan Kiepura Festival in Krynica Zdrój as a Tourism Product and Its Meaning for the Development of The City
Authors: Gładysz Elżbieta , Wszendybył-Skulska Ewa
Published: December 2018

Purpose. The aim of the article is to present the annual Jan Kiepura Festival in Krynica Zdrój as a tourism product as well as to draw attention to the importance of taking care of the jointly valued creation by all stakeholders for the development and long-term success of all events of that kind. Method. The study is the result of using the critical method of analysing literature on the subject, the press, media industry reports, the case study method in the form of in-depth analysis of data and secondary materials by institutions dealing with: organization/co-organization, documentation of history and services of visitors to the Krynica Zdrój Festival and also qualitative, partly, structured interview methods with representatives of the Krynica Tourist Organization, Prezydent, Stefania, Czarny Groń hotel owners, President of the Krynica Board– Żegiestów SPA, Żegiestów Spa, employees of the Board Office of Krynica – Żegiestów SPA, The main Pump Room, Public Library and the mayor of the city of Krynica-Zdrój. Results. The analysis of data showed that the Jan Kiepura Festival meets all the conditions to be described as a tourism product. In addition, it was proved that the success of the oldest festival in Poland is conditioned by the care for joint-value creation by all stakeholders. Research and conclusions limitations. The author’s research presented in the study focuses on the value which the town of Krynica Zdrój gains from the organization of this festival. However, this does not include a wider group of stakeholders (i.e. artists, music-lovers and tourists). Practical implications. The results of research provide information on how the festival can become a valuable tourism product for all its stakeholders, while, at the same time, being the basis for formulating recommendations for the organizers of festivals of any kind, including opera-related ones. Originality. The article concerns an opera festival which has never before been described as a tourism product. In addition, it shows what value the Jan Kiepura Festival generates for the town of Krynica Zdrój. Type of work: Review article.

CHANGES IN THE SPATIAL CONCENTRATION OF EMPLOYMENT ACROSS POLISH VOIVODSHIPS
Authors: Adamczyk Piotr
Published: December 2018

The aim of this paper was to recognize and assess the changes in the spatial concentration of employment across Polish voivodships and to compare the growth of number of employed persons in the different types of districts. The author used the Herfindahl-Hirschman Index to investigate whether the employment was becoming more or less concentrated. Using the data from Local Data Bank, it was indicated that in the period 2005-2016 the number of employed persons was rising at the fastest rate in the largest cities and their closest proximity. The growth rate was relatively slower in the medium-sized and small urban districts. It resulted in the increase of concentration coefficient of employment in 9 voivodships.
ASSESSMENT OF THE USE OF MACHINERY IN AGRICULTURAL FARMS WITH SPECIAL
PRESENTATION OF USEFUL COSTS
Authors: Hornowski Andrzej , Kondraszuk Tomasz
Published: December 2018

The paper attempts to introduce the notion of useful and useless (empty) costs into the assessment of the costs of mechanization. Useless costs are fixed costs and are related to maintaining the operational potential of the machines, which is not fully used. Useful costs are the part of fixed costs that are associated (absorbed) during the work (operation). It was assumed as a rational annual threshold for the use of machines the ratio of the technical potential of a given fixed asset throughout its useful life, expressed in units of labor (h, ha, km, t, pcs, coils, l), to its economic (moral) of work potential expressed in years. It was considered that the costs of unused production potential should be considered in the aspect of management costs (period costs) and they should not be charged to the costs of individual production activities.
ADVANTAGES AND DISA DVANTAGES OF LEGAL FORMS OF USING LAND FROM THE RESOURCES OF THE AGRICULTURA L PROPERTY OF THE STATE TREASURY IN THE LIGHT OF SURVEYS IN THE WAR MIAN-MAS URIAN VOIVODESHIP
Authors: Juchniewicz Małgorzata , Łukasiewicz Katarzyna
Published: December 2018

The purpose of research was to identify the advantages and disadvantages of the forms of development of farm lands using the grounds from the State Treasury Agricultural Property (STAP) in Warmińsko-Mazurskie voivodeship. In the opinions of researched group, the main advantage of lease was the opportunity to maintain the agricultural production in lower (than in the way of buying) prices. The most important disadvantage of the lease was insecurity of managing in longer perspective of time. The most important asset of buying the agricultural lands is the possibility of further investments in the farm without having to worry about losing the grounds. Respondents pointed out that the main disadvantage of buying the grounds is the high prices of such form of using.
COMPARISON OF MICROBIOLOGICAL QUALITY OF MILK PRODUCTS FROM ORGANIC AND CONVENTIONAL PRODUCTION
Authors: Kukułowicz Anita
Published: December 2018

The aim of the research was to compare the microbiological quality of dairy products derived from organic and conventional farming. The test material consisted of milk and milk products (natural yoghurt, cream, curd cheese, rennet ripening cheese, milk). Investigated products were subjected to microbiological analysis and marked for the number of Enterococcus sp., Staphylococcus aureus, yeast and moulds, Escherichia coli as well as to state the presence of Salmonella sp. in them. All samples were free of Salmonella sp. Escherichia coli occurred in 2 samples of curd cheese from organic production. Products derived from organic and conventional production didn’t differ in the average number of microorganisms depending on the type of dairy product, with the exception of ripening rennet cheese, which showed a significant difference in the amount of Staphylococcus aureus.
EFFICIENCY OF MILK FARMS ON THE BACKGROUND OF THE GENERAL FARMS THAT WERE COVERED BY THE FADN ACCOUNTANCY
Authors: Komorowska Dorota
Published: December 2018

The aim of the study was to assess the results of managing production resources in farms specializing in milk production against the background of the total number of agricultural holdings that were covered by agricultural accounting in the FADN system in 2016. The analysis covered the production and economic results as well as the productivity and profitability of land, labor and capital resources. The results of the surveyed farms presented in the study indicate a similar level of productivity of land resources in both groups of farms, higher labor productivity in dairy farms and lower capital in those farms. Farms specializing in milk production obtained economic results at a much higher level than total farms, therefore the profitability of production resources was also significantly higher in these farms.
FOOD PREFERENCES IN MEALS CONSUMED BY LONG-DISTANCE
TRUCK DRIVERS
Authors: Moturi Walter , Florkowski Wojciech J.
Published: December 2018

This preliminary study identifies individual characteristics and job features that significantly influence the selection of meat for breakfast and lunch by truck drivers in Kenya. Based on the survey data collected in July 2017, two equations are estimated using the logit technique. Results show that individual characteristics drive the choice of non-meat foods for breakfast, while job features and environment encourage meat selection for lunch. Having formal education lowers the probability of choosing meat for either meal, but taking hitchhikers strongly encourages eating meat for lunch, likely due to the additional income from fees paid by travelers to the driver.
FOOD SAFETY IN THE CONTEXT OF LEGISLATION
Authors: Ozimek Irena
Published: December 2018

The study aims to analyse selected legal regulations concerning the issue of food safety, regarding both health safety and protection of consumers' economic interests as well as to present institutional possibilities of consumer protection in the food market in this area. As a result of the analysis of selected legal regulations, it can be concluded that there are numerous legal acts covering the issue of food safety. Changes that occur in food law as well as creation of new organizations at the level of the European Union preventing food counterfeiting, will contribute to ensuring a higher level of consumer protection on the food market in the European Union, including Poland.
CHANGES IN PRODUCTIVITY AND PROFITABILITY OF WORK IN DAIRY FARMS FROM SELECTED EUROPEAN UNION COUNTRIES IN 2005-2015
Authors: Parzonko Andrzej
Published: December 2018

The main objective of the article was to present changes in productivity and profitability of work in dairy farms from selected EU countries diversified by economic size in 2005-2015. The subject of research is milk farms from seven EU countries with the largest increase in milk commodity production in 2005-2015. The analysis shows that: 1) Work productivity in EU dairy farms in 2015 was highly diversified and Polish farms were characterized by the lowest work productivity; 2) The level of work efficiency was not directly correlated with the profitability of the farmer’s own work. Polish dairy farms, especially from the group with an economic size of PLN 100,000 - 500,000 euro, were characterized by average similar profitability of their own work as farms from Germany, the Netherlands and France. An interesting example is dairy farms from Denmark, which were characterized by the highest work productivity and farm income per hour of own work was the smallest.
REGULATION OF WEEDS AS A FACTOR AFFECTING THE PROFITABILITY OF NARROW-LEAFED LUPINE PRODUCTION
Authors: Pawłowski Krzysztof Piotr
Published: December 2018

The purpose of the article is to determine the economic effectiveness of herbicidal treatments used in the cultivation of narrow-leafed lupine in the aspect of the profitability of its production. The domestic production of leguminous plants in only 30% covers the need for protein needed for the production of feed. In this way, Poland is conditioned on the import of soybean meal, which has a negative impact on its food security. Narrow-leaved Lupine is one of the basic species of legumes which are grown in Poland. Nevertheless, relatively few farmers decide to grow it due to low profitability, which is primarily related to the lack of optimal methods of weed control. The research was carried out on the basis of a field experiment in a randomized block arrangement. On the basis of the results obtained, the direct surplus resulting from the use of individual herbicides was determined, which was positive for all combinations. A negative, strong correlation between the number and fresh weight of weeds and the obtained yield was also found. In addition, a model was created to determine the level of yield depending on the condition and degree of weed infestation.
HOUSING CONDITIONS OF RURAL HOUSEHOLDS IN POLAND COMPA RED WITH SELECTED COUNTRIES OF THE EUROPEAN UNION
Authors: Siedlecka Agnieszka
Published: December 2018

The aim of the paper was to analyze the housing conditions of households living in rural areas in Poland against a background in selected European Union countries. The household as a basic subject of economic life has limited resources. One of the elements of these resources is a flat. Both its area, equipment and infrastructure are an important element affecting the quality of life. The analysis of statistical data showed that worse conditions, described using the average number of rooms per person in households, were in Poland in comparison with other European Union countries. The statistical data for 2017 collected by the Statistical Office of the European Union (Eurostat) were used in the article.
Progranulin in neurodegenerative diseases
Authors: Harmata Barbara , Jędrzejowska-Szypułka Halina , Pawletko Katarzyna , Lewin-Kowalik Joanna
Published: December 2018

Neurodegenerative diseases as a group of congenital or acquired diseases of the nervous system are currently more common in the aging societies, being one of the most severe diseases faced the healthcare services. Many scientific teams are searching for a better understanding of the mechanisms of these diseases, i.e. their detection, treatment as well as putative prevention methods. Progranulin is one of the twenty-first century discoveries and is a precursor of multifunctional cysteine-rich proteins granulins, which play a crucial role in cell development, cell cycle control, wound healing, inflammatory and cancerogenic processes, neuron development, and neurodegeneration. In 2006, the first mutation in the gene encoding progranulin was discovered as the cause of frontotemporal dementia (FTLD). The human PGRN sequence was first fully characterized on the basis of mRNA isolated from bone marrow cells. Up to now, more than 75 mutations have been reported in patients with various forms of FTLD. All discovered mutations cause the disease either by loss of function of the entire progranulin protein or loss of function of one allele of the PGRN gene. Taking into account the available
data regarding PGRN, we would like to collect and systematize the data about progranulin and
its putative usefulness as a prognostic factor in some neurodegenerative diseases. The role of
progranulin in neurodegenerative diseases is invaluable, not only as a prognostic factor in the
presymptomatic stage of the disease but also as a chance for its future therapeutic application
in neurodegenerative diseases. Low levels of progranulin were found to correlate with either
prodromal symptoms or even asymptomatic stages in patients with established mutations in
the progranulin-encoding gene. Research currently in progress provides valuable information
about the possibility of this protein being used to improve the diagnosis as well as treatment
of different neurodegenerative diseases.

Measurement invariance of the perceived online racism scale across age and gender
Authors: Keum Brian TaeHyuk , Miller Matthew J.
Published: December 2018

The Perceived Online Racism Scale (PORS) is the first measure specifically developed to assess online racist interpersonal interactions and exposure to online racist content. To advance and strengthen the psychometric foundation of the PORS, the current study evaluated the measurement invariance of PORS across gender and age, two major demographic categories that can differentially affect how racism is perceived. Based on the framework of intersectionality, the salience and significance of social identities, such as gender and age, influence how racism is perceived with different meanings and interpretations. The current study examined data collected through an online survey from 946 racial/ethnic minority participants (59% women, mean age = 27.42) in the United States. Measurement invariance across gender (men and women) and age groups (ages 18 to 24, 25 to 39, and 40 to 64) was tested via comparison of a series of models with increasing constraints. Measurement invariance across configural, metric, and scalar models for age and gender was supported. Latent means were compared across gender and age groups. The results advance the psychometric property of the PORS as a general measure of online racism. Differences in the PORS scores reflect true differences among gender and age groups rather than response bias. Implications for future research are discussed.

OS LIMITES DA FALSEABILIDADE COMO CRITÉRIO DE DEMARCAÇÃO PARA CIENTIFICIDADE
Authors: Pires Guilherme Nunes
Published: December 2018

O objetivo do presente artigo é indicar os limites do critério de demarcação para cientificidade proposto por Karl Popper. O problema de demarcação tem sido objeto de preocupação em diferentes épocas da história. Entretanto, o século XX foi acompanhado por intensos debates e pela elaboração de distintos critérios que pudesse demarcar conhecimento científico dos demais. Também é notório que o pensador que mais obteve significância foi Karl Popper e seu critério de falseabilidade. Contudo, o caráter puramente negativo do empreendimento científico, sob sua abordagem unicriterial, compreende uma espécie de positivismo invertido, onde suas limitações apresentam ser um critério de demarcação não necessário e/ou suficiente para a cientificidade.

Las vidrieras de la Catedral de Jaén = Stained Glasses in Jaén Cathedral
Authors: Casuso Quesada Rafael
Published: December 2018

El estudio de las vidrieras de la Catedral de Jaén nos lleva a establecer dos tipos: el de las translúcidas, correspondientes al gusto clasicista de los siglos XVI al XVIII, y el de las decorativas, de principios del siglo XX. Carecemos de noticias documentales acerca del pensamiento del arquitecto Andrés de Vandelvira en su proyecto original, si acorde con los programas goticistas ejecutados por entonces en otras catedrales españolas o afín a las nuevas ideas de iluminación «blanca» del Renacimiento italiano. Un estudio del inventario de bienes efectuado a su fallecimiento nos revela la posesión de dos libros del tratadista Sebastiano Serlio, quien ya apostaba por el empleo de vidrieras geométricas, no decorativas. La constatación de esta nueva estética en los continuadores de la obra de Vandelvira es evidente. Una comparación del efecto lumínico entre las vidrieras clasicistas y las historicistas nos da idea de dos concepciones abismales del tratamiento de la luz. A study of stained glasses in Jaen´s Cathedral leads us to distinguish two different types: the transparent ones, corresponding to the classicist taste from the XVI-XIX centuries on the one hand and the ornamented or stained ones, dating back from the beginning of the XX century, on the other. Unfortunately we lack information from Vandelvira´s --the main architect of the Cathedral--original project: whether it was according to the gothic prevalent ideas, which were carried out in many of the Spanish cathedrals at that time, or embraced the new ideas from the Italian Renaissance, which were in favour of a «white light» instead. A survey of the inventory of his goods, made after he died, reveals that Vandelvira was in possession of two of Sebastiano Serlio´s books on architecture. They show that Serlio was in favour of using transparent glasses.  The verification of this new aesthetic in the followers of the work of Vandelvira is evident. A comparison of the luminous effect between classicist stained-glass windows and historicist windows gives us the idea of two totally opposed conceptions of the treatment of light.
Plateros tardogóticos de Valladolid al servicio de la Casa Ducal de Medinaceli. A propósito de ciertas joyas para Doña María de Silva y Toledo = Late Gothic Master Silversmiths from Valladolid at the Service of the Ducal House of Medinaceli: Jewels for Doña María de Silva and Toledo
Authors: Romero Medina Raúl
Published: December 2018

A principios del siglo XVI, la Casa Ducal de Medinaceli era una de las familias aristocráticas más distinguidas en Castilla. El matrimonio formado por los II duques de Medinaceli, don Juan de la Cerda y doña María de Silva y Toledo, desarrolló una especial sensibilidad hacia el arte y la cultura. Los encargos de joyas para la duquesa de Medinaceli son una prueba de ello y permiten avanzar en el conocimiento de su valor y los nombres de los plateros, orfebres tardogóticos, que se vieron implicados, así como contextualizar el foco de Valladolid y los marcadores de plata que se documentan como Abdinete o Francisco de Cuenca, cuyos punzones se distinguen hoy en otras piezas conservadas.At the beginning of the 16th century, the Ducal House of Medinaceli was one of the most distinguished aristocratic families in Castile. The couple formed by Don Juan de la Cerda and Doña Maria de Silva and Toledo developed a special interest in art and culture. Jewelry orders for the Duchess of Medinaceli prove this interest and allow us to know their value, and the names of the late Gothic master silversmiths and goldsmiths who were involved in the process. This study also allows us to contextualize Valladolid and the markers of silver that are documented as Abdinete or Francisco de Cuenca, whose bodkins are still recogized today in other preserved pieces.

Body of Knowledge: Renaissance Armor and the Engineering of Mind = Cuerpos del conocimiento: armaduras del Renacimiento y la ingeniería de la mente
Authors: Jäger Felix
Published: December 2018

This essay charts the role of armor in Renaissance practices of knowledge. Since the advent of gunpowder warfare, armor was largely unfit for combat, yet still became a centerpiece of princely representation and was prominently displayed in early collection spaces. Rather than illustrating chivalric virtues or antiquarian taste, such suits in my reading signal a shift towards a physiological fashioning of learning. Through juxtaposing two key sets of armor – one ‘gothic’ suit situated in the studiolo, the other a ‘grotesque’ garniture for a chamber of curiosities –, my paper traces how these embodied settings conflated epistemological with political sensibilities. While the earlier ensemble acted as a mnemonic ‘prosthesis’ that enhanced the mind of the wearer, the latter evoked natural history imagery to remap the order of things around personal authority. Objects of armor thus spotlight the interplay of material and political culture in engineering the early modern subject.El presente ensayo traza el papel de las armaduras en las costumbres renacentistas del conocimiento. Desde la aparición de las armas de pólvora, las armaduras dejaron de ser apropiadas para el combate, si bien todavía constituyeron una pieza central de representaciones principescas y fueron ampliamente expuestas en espacios de colección. En lugar de ilustrar las virtudes caballerescas o los estilos como antigüedades, estas vestimentas señalan, a mi entender, un giro hacia el conocimiento fisiológico de la moda. A través de la yuxtaposición de dos conceptos clave de las armaduras –uno como vestimenta gótica emplazada en el studiolo (taller de arte), otro como decoración «grotesca» en una sala de curiosidades – mi texto indaga cómo estos elementos ajustados al cuerpo confrontaban las sensibilidades epistemológicas y políticas. Mientras que las primeras actuaban como una prótesis que fortalece la mente del que las usa, las segundas evocan la imaginería de la historia natural para recolocar el orden de las cosas alrededor de la autoridad personal. Las armaduras enfocan de este modo la interacción entre la cultura material y la política en el desarrollo del sujeto moderno.

Wearing images. Introduction = Imágenes portadas. Introducción
Authors: Bodart Diane H.
Published: December 2018

In the past decades, studies on the materiality and the efficacy of images, as well as the artistic and social practices related to them, have allowed scholars to explore how much images’ making, use, handling and display contributed to the activation of their powers of presence through their interaction with the viewer. Further, the growing interest in the articulation between the history of art and the anthropology of images has brought to light the close links between the art object and the body: in fact, if the body can be the medium of the animate art object, the art object can potentially act as a substitute of the animate body. But what happens when the body is the support of a distinctive image, when it inscribes an image on its own surface, whether directly on the skin or through intermediary props such as clothing or corporeal parure? Wearing Images investigates the different modes of interaction between the image and the body that wears it in the Early-Modern period, when devotional, political, dynastic or familial images could be worn as medals, jewels, badges, embroidered garments or tattoos.En las últimas décadas, los estudios sobre la materialidad y la eficacia de las imágenes, así como de las prácticas artísticas y sociales asociadas a ellas, han permitido a los historiadores explorar hasta qué punto la fabricación de las imágenes, su uso, manejo y exhibición contribuyó a activar sus capacidades de presentarse a través de su interacción con el espectador. Además, el creciente diálogo entre la historia del arte y la antropología de las imágenes ha puesto de relieve las estrechas conexiones entre el objeto artístico y el cuerpo: en efecto, si el cuerpo puede ser el medio para el objeto artístico animado, el objeto artístico puede actuar potencialmente como sustituto del cuerpo animado. Pero ¿qué ocurre cuando el cuerpo es el soporte de una imagen distintiva, cuando inscribe una imagen en su propia superficie, ya sea directamente en la piel o a través de intermediarios como el vestido o un adorno? Wearin Images investiga las diferentes modalidades de interacción entre la imagen y el cuerpo que se viste con ella en la Edad moderna, en una época en la que imágenes devocionales, políticas, dinásticas o familiares podían vestirse como medallas, joyas, placas, prendas bordadas o tatuajes.

RESUMENEl objetivo de este trabajo, que forma parte de un proyecto de innovación docente más amplio, fue diseñar un plan concreto de orientación universitaria dirigido a los estudiantes de nuevo ingreso en la universidad. Se partió de las necesidades del alumnado, detectadas previamente en otro estudio, y a través de pequeños grupos de trabajo cooperativo y grupos de discusión formados por tutores, mentores y expertos en orientación se realizó la programación de las diferentes acciones de orientación y su distribución temporal para un curso escolar. Posteriormente se desarrollaron diseños concretos de propuestas de intervención para cada una de las sesiones de orientación, con materiales que sirviesen de guía y ejemplo para la acción orientadora de tutores y mentores. Tras la aplicación del programa en un curso académico se procedió a la evaluación de las acciones de orientación y de los materiales diseñados. Un 69.5% de estudiantes, un 88.9% de mentores y un 83.3% de tutores están de acuerdo o muy de acuerdo en que las actividades programadas resultaron útiles. En cuanto a los materiales, un 57.2% de estudiantes y prácticamente la totalidad de mentores y tutores están de acuerdo o muy de acuerdo en que fueron útiles. Los resultados confirman el impacto positivo del proyecto, que además podría ser transferible a otros centros. ABSTRACTThe objective of this work, which is part of a wider educational innovation project, was to design a concrete plan for university orientation aimed at new students entering university. Based on the needs of the students, previously identified in another study, and through small cooperative work groups and discussion groups of tutors, mentors and guidance experts, the different guidance actions were programmed and distributed over a school year. Subsequently, concrete intervention designs were developed for each of the orientation sessions, with materials that served as a guide and example for the guiding action of tutors and mentors. Following the implementation of the programme in an academic year, the orientation actions and the materials designed were evaluated. 69.5% of students, 88.9% of mentors and 83.3% of tutors agreed or strongly agreed that the activities planned were useful. In terms of materials, 57.2% of students and almost all mentors and tutors agree or strongly agree that they were useful. The results confirm the positive impact of the project, which could also be transferred to other centres.

Protein histidine methylation is a rare post-translational modification of unknown biochemical importance. In vertebrates, only a few methylhistidine-containing proteins have been reported, including β-actin as an essential example. The evolutionary conserved methylation of β-actin H73 is catalyzed by an as yet unknown histidine N-methyltransferase. We report here that the protein SETD3 is the actin-specific histidine N-methyltransferase. In vitro, recombinant rat and human SETD3 methylated β-actin at H73. Knocking-out SETD3 in both human HAP1 cells and in Drosophila melanogaster resulted in the absence of methylation at β-actin H73 in vivo, whereas β-actin from wildtype cells or flies was > 90% methylated. As a consequence, we show that Setd3-deficient HAP1 cells have less cellular F-actin and an increased glycolytic phenotype. In conclusion, by identifying SETD3 as the actin-specific histidine N-methyltransferase, our work pioneers new research into the possible role of this modification in health and disease and questions the substrate specificity of SET-domain-containing enzymes.
Mass Spectrometry and Gas‐Phase Ion Chemistry of Hypervalent Halogen Compounds
Authors: O'Hair Richard A. J.
Published: December 2018

Studies relevant to the gas‐phase formation, reactions, structure, thermochemistry, kinetics, and mass spectrometry of hypovalent halogen compounds are reviewed. The types of species considered include two‐center–three‐electron bond dimer radical cations of methyl halides; aliphatic, aromatic, and cyclic halonium ions; charged iodonium compounds; neutral iodonium compounds and their reaction products with organic substrates; iodosobenzene and its analogs and their adducts with transition metal complexes; and other oxides of halides. These studies highlight the broad scientific interest in the interaction of hypovalent halogen compounds, which span the range from traditional organic and organometallic chemistry, catalysis through to the development of methods for proteomics.
Reference tracking control and attenuation of unknown periodic disturbances in the presence of noise for unknown minimum‐phase LTI plants
Authors: Jafari Saeid , Ioannou Petros A.
Published: December 2018

The rejection of unknown periodic disturbances in the plant output through adaptive feedback has been an active area of research. In most successful efforts, it is assumed that the plant model is a known LTI stable system. In this paper, we relax the assumption of stable known plant and consider the case where the plant model can be unstable with unknown parameters. We do assume, however, that the plant model is minimum phase and use the model reference adaptive control structure to meet the objectives of reference tracking and unknown periodic disturbance rejection without amplifying the effect of broadband noises. The cost of achieving these objectives is the use of overparameterization that adds to the number of computations. The main contribution of this paper is that it shows that the problem of rejecting unknown periodic disturbances can be solved for unstable plants with unknown parameters as long as they are minimum phase. Numerical examples illustrate the effectiveness of the proposed control methodology.
Highly Active Co‐Based Catalyst in Nanofiber Matrix as Advanced Sensing Layer for High Selectivity of Flexible Sensing Device

Published: December 2018

An efficient and economic sensing material for flexible chemical sensors is increasingly in great demand as a result of its potential application in the healthcare and environmental detection systems. Endowing the nanomaterials with high active facets serves as a promising method for the design of nanomaterials with advanced functionalities. New physicochemical properties of chemical sensor can be obtained by using high active facets nanoparticles combined in one‐dimensional (1D) nanofiber/wires. However, it remains a great challenge to conduct the development of 1D heterostructure sensing materials with high selectivity, in particular the ones that can perform under room temperature. Here, a high performance flexible sensing device based on Co3O4 nanoparticles with specific (112) facet in α‐Fe2O3 nanofiber is reported. The heterointerfaces and grain boundary allow the fast electrons transportation in sensing reactions and the (112) facets in Co3O4 nanoparticles provide a large number of highly active sites where the selective absorption of ammonia gas molecules occurs. Consequently, the flexible gas sensor exhibits ultrahigh sensitivity (417%) and mechanical stability to ammonia gas molecules, which are proved by using density functional theory calculations.
The Praxis of Decoloniality in Researcher Training and Community‐Based Data Collection

In this paper, we detail our praxis of decoloniality in the context of a community‐based study that employs a quantitative experimental methodology to evaluate an intervention for girls involved in the juvenile legal system. We resist the essentializing of methodology that positions quantitative paradigms as impermeable to reflexivity and decoloniality, and describe a model for training and supervising researchers engaged in an experimental randomized controlled trial of an advocacy program for girls, most of whom are girls of color and about half of whom identify as LGBT. In this way, we consider researcher training as a critical teaching context and describe the ways in which our training, community‐based data collection, and supervision structure are anchored in de/anti/post colonial and indigenous scholarships. Specifically, our praxis is centered on conducting research as a site of resistance to hegemony, and practicing a critical compassion rooted in remembering complex personhoods. We further discuss the boundaries and limitations of our own epistemic power in relation to two central questions: how can researchers influence how knowledge is produced? How can researchers influence how knowledge producers are themselves produced?
