Normative Regulation: Significance, Place, Roles and Protection of Private Archival Material and Private Archives with a View on the Regulation in the Republic of Serbia and Montenegro
Authors: Popović Jovan P.
Published: May 2019

In addition to public-state archives, as a rule, there are private and special archives in each state. The laws regulate who their founder is, what conditions are necessary for the establishment and operation of the archives, what governing bodies are and what their competencies are. In the period of transition, in the countries of socialist organization, there was a real „boom“ for purchasing companies, when state and social ownership was transitioning into private. A large number of companies experienced bankruptcy and liquidation institutes. However, the achival material of these subjects remained normatively unprotected. In this paper, the author deals with short legal definitions and the history of the creation of private archives at the time and after transitional relations, on the territory of the former Yugoslavia, with a special emphasis on the legal arrangements in the states of Serbia and Montenegro, with the aim of regulating the laws and by-laws protection and use of this material as closely as possible.
Diocesan Archives in Slovenia During the Second Half of the 20th and the Beginning of the 21st Century
Authors: Rehar Marija čipić
Published: May 2019

The article deals with the development of diocesan archives in Slovenia since the end of the Second World War until today. It provides information on the construction of three diocesan archives in Koper, Ljubljana and Maribor. The archive in Koper is the youngest, since the state borders of the Primorska region were determined long after the end of the Second World War and the previous diocesian archives in that area remained outside the borders of Slovenia today. The Archive in Ljubljana operated all the time since after the war and in 1993, with the return of the registries which the state seized after the war on parishes, it enlarged. Until 1993-1994, the archive in Maribrt operated within the Maribor Regional Archives, so that the diocese‘s archivists were employed there.
Independent Community Archives: Challenging the Status Quo of Private and Public Archives
Authors: Gilliland Anne J. , Štefanac Tamara
Published: May 2019

The community archives movement has emerged as a prominent, and often critical, presence within, and also outside the archival traditions and practices in North America and the United Kingdom. They can take many forms and often contest how both public and private archives in these regions have historically been understood, structured and operated. This paper first presents a brief review of some of the ways in which community archives have been framed in the archival literature. It then considers several questions regarding how such framings of community archives might challenge the status quo of private and public archives as currently defined and organized under the recently revised Croatian legislative framework and proposes a more conciliatory approach.
The Archivist Between His Duty to Communicate and the Obligation to Protect
Authors: Kouda Alizata
Published: May 2019

Information is an essential and unavoidable fact both in terms of the development of individuals’ leadership and the emergence of companies and societies we’re living in as well. All activities revolve around data and information created or received. These different natural or legal persons aspire to faster access to information. To this end, information and communication technologies are increasingly being used for so-called free access information and need for documentary information managers (archivists, librarians and documentalists) for information related to institutions also increases. With regard to the latter type of information contained in documents held by public administrations, more and more users are wanting to access it, almost without delay, lying on their right to information. However, this consecrated right is not without restriction. These restrictions are linked, among other things to the safety of the state and to the protection of privacy. In this context, the guarantors of the institutional memory that are the archivists, are facing a dilemma: to communicate information to users while ensuring the protection of the privacy of citizens.

Analysis of Prion Protein Coding Gene Polymorphisms in Palestinian Native Sheep Breeds
Authors: ALSAYED Osama , ERKUNT ALAK Sedef , ÜN Cemal
Published: May 2019

Prion protein coding gene (PRNP) is the genetic locus correlated with the greatest impact on classical scrapie susceptibility in sheep. At codons 136, 154, and 171 of PRNP alanine/arginine/glutamine (ARQ) and valine/arginine/glutamine (VRQ) haplotypes, in turn, are related to susceptibility to classical scrapie while alanine/arginine/arginine ARR haplotype is correlated with resistance. The aim of the present study was to genotype the Palestinian native sheep breeds for detection of genetic resistance. A total of 38 healthy sheep from Awassi and Assaf breeds were randomly sampled. Genomic DNA was isolated from blood samples. After PCR amplification and DNA sequencing, ARQ, ARR, ARH, AHQ, ARL and VRQ alleles and ARR/ARQ, ARQ/ARQ, ARQ/ARL, ARH/ARQ, ARH/ARL, AHQ/ARQ and ARQ/VRQ genotypes were detected in PRNP gene. ARQ allele was found as a predominant allele in this study with the frequency of 0.76 for Awassi and Assaf breeds while the uncommon allele ARL was identified at low frequencies in both breeds. In addition, two different polymorphisms were recognized (V12I and L23H) at different codons of PRNP. Results have indicated that most of the genotypes belong to risk group 3. The careful dissemination of ARR/ARR sheep is suggested to increase resistant allele frequencies in Assaf and Awassi breeds.

Análisis de técnicas de manufactura de alfarería prehispánica tardía en el Noroeste Argentino (siglos XIII-XVII d.C.). Una contribución del estilo Sanagasta/Angualasto del sito Tambería de Guandacol (provincia de La Rioja)
Authors: Carosio Sebastián A.
Published: May 2019

En este trabajo se presentan los resultados sobre el estudio de las técnicas de manufactura involucradas en la producción alfarera del sitio Tambería de Guandacol, departamento de Felipe Varela, provincia de La Rioja (Argentina). Las piezas cerámicas se corresponden con el Estilo Sanagasta/Angualasto, asociado fundamentalmente a la época prehispánica tardía en el Noroeste Argentino (siglos XIII-XVII d.C.). A partir de un registro esencialmente fragmentario y mediante la combinación de estudios traceológicos y de petrografía cerámica, se pretende avanzar en el conocimiento de la cadena operativa y organización de la producción alfarera de los grupos que habitaron el valle durante dicho lapso. Asimismo se discuten los alcances y limitaciones de este tipo de estudio sobre registros fragmentarios. Los resultados han permitido registrar una elección uniforme de técnicas primarias y secundarias para la confección de recipientes y cierta irregularidad en los modos de aplicación. Igualmente, se reconocen semejanzas tecnológicas con producciones contemporáneas del área. El panorama permite plantear la existencia de un proceso de fabricación generado por un mismo grupo comunitario, con diferentes agentes involucrados y enmarcados en una tradición tecnológica basada en prácticas de enseñanza/aprendizaje cotidianas, con fuertes lazos sociales y culturales.
Planning new public transport line based on accessibility criteria
Authors: Gadziński Jędrzej , Bul Radosław
Published: May 2019

The changing role of public transport in Polish cities and contemporary urbanisation processes can be recognized as the most important reasons for the rapid development of bus and tram networks in last years. It seems that a key factor which could attract new passengers is the improvement in the level of accessibility. Therefore, the main aim of this article is to present a methodology based on the accessibility measures, which could help in the planning of the public transport networks in urban areas. Świerczewo district in the southern part of Poznań was adopted as an research area. Conducted analyses showed that the proposed method could help in the selection of an optimal bus line and stops location. The conclusion is that such an objective approach should be taken into account when the decisions on the future of public transport networks will be made.

Published: May 2019

The paper refers to the history of the transfer voivodship self-government the responsibility for organizing and funding regional railway with the submission in 2008 by the Treasury that local governments ownership of the company's Regional Transport. In 2016, the reform has not yet been fully completed, however the process of transfer the ownership resulted in many positive phenomena in the whole Polish railway transport. In particular, it solved the problem of the location of the target company's Regional Transport on rail passenger market, although in the years 2014 - 2015 could be observed significant improvements in financial and economic situation - this financial company. In the final part of the paper indicated that the current structure of economic and ownership on the Polish rail passenger market can and should undergo further changes and transformations. The target solution is the privatization of companies in the whole rail passenger sector, although it is not will happen quickly, because a significant part of the Polish political class is not prepared for such a solution.

Strengthening of a road bridge due to a very large load
Authors: Machelski Czesław , Hildebrand Maciej
Published: May 2019

Extremely heavy oversized transport is considered in the paper. Such oversized loads appears occasionally along the road network due to the restrictions of load capacity of bridges. The results of the analyses involved in the paper shows that old bridges as well as new ones are not adapted to such oversized loads. The strengthening or reconstructions of structural ele-ments are required as presented in the paper. The final remark refers to the administrative un-derstanding of the load capacity of the bridge which is based on the total weight of a vehicle. Such approach of the load capacity is not precise.

Learning Analytics para una visión tipificada del aprendizaje de los estudiantes. Un estudio de caso
Authors: De la Iglesia Villasol Mª Covadonga
Published: May 2019

Los nuevos métodos de enseñanza-aprendizaje, con apoyo de los entornos virtuales, como extensión asincrónica de las aulas, han determinado que el docente asuma nuevos roles, algunos de los cuales pasan por aumentar su capacidad de observación y convertirse en analista del proceso de aprendizaje de los estudiantes, del uso que hacen de las plataformas digitales, su interrelación con ellas y entre sí, y de cómo adquieren conocimientos y desarrollan algunas competencias. Desde ésta óptica, el trabajo aborda una primera explotación de los usos y registros estadísticos, que a modo de huella digital, dejan los estudiantes en cursos presenciales en los espacios virtuales, y que definen tipologías y patrones diferenciados de aprendizaje según ritmos, aspecto éste que puede conllevar a una reflexión y reorientación del proceso de enseñanza-aprendizaje futuro. En concreto, el estudio de caso recoge resultados descriptivos de la interacción del uso que los estudiantes realizan de los recursos digitales con la evaluación continua y las calificaciones en la asignatura de Análisis Microeconómico Avanzado, del grado en Economía (GECO), UCM en el curso 2018-19, aportando un perfil de uso aún muy tradicional y polarizado, vinculada con mínimos desfases al cronograma de las actividades propuestas por el profesor.

Six Years of Sustained Activity in (6478) Gault
Authors: Chandler Colin Orion , Kueny Jay , Gustafsson Annika , Trujillo Chadwick A. , Robinson Tyler D. , Trilling David E.
Published: May 2019

We present archival observations demonstrating that main belt asteroid (6478) Gault has an extensive history of comet-like activity. Outbursts have taken place during multiple epochs since 2013 and at distances extending as far as 2.68 au, nearly aphelion. (6478) Gault is a member of the predominately S-type (i.e., volatile-poor) Phocaea family; no other main belt object of this type has ever shown more than a single activity outburst. Furthermore, our data suggest that this is the longest duration of activity caused by a body spinning near the rotational breakup barrier. If activity is indeed unrelated to volatiles, as appears to be the case, (6478) Gault represents a new class of object, perpetually active due to rotational spin-up.
Ressources foncières et nouvelle frontière agricole dans le désert égyptien : le rôle décisif de l’armée
Authors: Acloque Delphine
Published: May 2019

Au cœur de grands projets de mise en valeur agricole, les terres du désert égyptien sont des ressources convoitées par une diversité d’acteurs qui se projettent sur ces espaces et cherchent à faire valoir leurs intérêts respectifs : produire et commercialiser des denrées agricoles bien sûr, mais aussi accroitre leur pouvoir ou légitimer leur position. Indissociable du processus de bonification de ces terres depuis la période nassérienne, le rôle des forces armées a été fortement réaffirmé dans les dernières années, avec l’arrivée au pouvoir du président Sissi et le projet de mise en valeur d’un million et demi de feddans. Cet article interroge la place de l’armée et ses intérêts – directs et indirects – dans la construction et l’essor d’une nouvelle frontière agricole en Égypte.
Palestinian Rural Realities between the Israeli Occupation and “Farming Modernisation”. The Case of the Village of Wādī Fūkīn (West Bank)

À travers l’étude de cas du village rural de Wādī Fūkīn, situé dans la région sud-ouest de Bethléem (Cisjordanie), cet article met en lumière les processus qui ont conduit à la diminution de la production agricole et à l’insécurité alimentaire dans les Territoires palestiniens. Il vise entre autres à montrer les implications écologiques, économiques et sociopolitiques locales des stratégies d’aménagement du territoire et des politiques administratives et économiques d’Israël, mais aussi de la supposée « modernisation de l’agriculture » encouragée par les agences de développement. Il souligne aussi les stratégies agricoles quotidiennes des villageois pour continuer à cultiver et lutter pour leur sécurité alimentaire et la reproduction matérielle et socioculturelle de leur famille et de toute la communauté.
Crise entre pétromonarchies du golfe Persique : une recomposition des solidarités alimentaires arabes ?
Authors: Lavandier Jérôme
Published: May 2019

Les modalités de production et de distribution d’aliments dans les provinces arabes du golfe Persique ont peu varié pendant des millénaires. L’ordre agricole et alimentaire dessiné sous l’Antiquité n’évolue réellement qu’à partir des années 1960 avec l’essor des industries pétrolières et gazières, puis de la période 2007-2008 en réaction aux crises alimentaire, financière et économique mondiales. Unis par leur dépendance aux importations alimentaires, les États membres du CCEAG se déchirent cependant politiquement depuis l’embargo mis en place autour du Qatar en juin 2017. La mise à mal de la sécurité alimentaire qatarienne au début de cette crise a révélé les faiblesses des solidarités arabes. Elle a aussi stimulé de nouvelles alliances qui traduisent des divisions durables entre pétromonarchies et accroissent l’influence des fournisseurs étrangers de matières premières agricoles dans un contexte marqué également par la volatilité des prix de ces dernières.
Une bureaucratie para-étatique mouvante
Authors: Vommaro Gabriel
Published: May 2019

Depuis les années 2000, des politiques d’assistance aux catégories les plus instables des classes populaires se consolident en Argentine comme dans la plupart des pays de l’Amérique latine. Une partie de ces politiques est gérée de manière conjointe par des dirigeants et des activistes locaux de partis et de mouvements sociaux. Il s’agit d’une véritable coproduction de l’intervention sociale de l’État dans les quartiers populaires. Basé sur un travail ethnographique dans trois quartiers populaires argentins, cet article analyse la production quotidienne des politiques sociales et notamment les activités de ses médiateurs qui jouent le rôle de bureaucrates para-étatiques. Issus eux-mêmes des classes populaires, ils sont à la fois des relais – pas toujours institutionnalisés – de l’État dans les quartiers populaires et des courroies de transmission des demandes des habitants de ces milieux face à l’État. L’analyse montre que le statut instable et les conditions de travail de ces bureaucrates, ainsi que leurs relations de dépendance avec les fonctionnaires étatiques les habilitant à distribuer des biens publics sont centraux pour comprendre les traits fondamentaux du rapport à l’État des couches les plus instables des classes populaires comme des logiques de fonctionnement du Welfare dans ces quartiers.

Published: May 2019

Internet addiction (IA) is typically defined as a condition where an individual has lost control of their internet use and proceeds to use the internet excessively to the point where he/she experiences problematic consequences which ultimately have a negative effect on his/her life. The authors examine what constitutes an addiction, the definition of internet addiction, the complications which exist in the various diagnostic methods of successfully diagnosing internet addiction, the criticism some of these diagnostic methods have taken and the effects of excessive internet use by both students and employees. They also highlight those individuals who are of increased risk of developing this condition including positive diagnosis of the addiction and the resultant effects it has on the individual's family life, employment, social life and personal wellbeing, before finally looking at possible methods and treatments that can be employed for treating internet addiction.

Published: May 2019

The article discusses the problem of digital addiction among adolescents and young adults within the context of socio-anthropology. Given the presence of this problem, we formed, as part of a project at the faculty and part of the psychotherapeutic approach to the treatment of the problem, an individual and a group program for the psychosocial treatment of digital addiction for adolescents and young adults. In the present article we clearly present both programs, which represent an innovative curative quality program. Both are designed coherently and focus on the manifested symptoms as well as on the treatment of the psychosocial background. They are designed on the basis of positive foreign practices, are adequately upgraded with consultative-therapeutic modality elements and are designed systematically and continuously, with the proper context and activity upgrade all the way up to the adolescent's regain of control over his life.

Authors: Titov Vyacheslav , Garanenko Tetiana
Published: May 2019

The method and unit for experimental research of membrane formation from titanium alloys under conditions of superplastic is developed, which allows to determine necessary parameters of deformation. The unit is designed to deform titanium sheets in isothermal conditions by applying a uniform distributed load. When membrane is formed by a gas medium, a biaxial tension is realized. This type of test is used to assess the plastic properties of metals. In this work, the limiting deformations of the sheet titanium alloy OT4-0 have been evaluated in the formation of the membrane. Installed during the process of superplastic deformation the connection between the external parameters of deformation (force, temperature) with the depth of formation of the membrane in time and strain distribution along its generatrix.

Authors: Zhuravel Oleksii , Derbaba Vitalii , Protsiv Volodymyr , Patsera Sergey
Published: May 2019

The aim of this work is to develop a methodology for graphically analytical calculation of angles of chip formation process for the case when the initial data are reliable empirical dependencies for the cutting forces’ components and value of shearing angle are obtained experimentally. The research method is based on the application of the elements of cutting theory with respect to flow chip formation scheme and the model of plastic deformation of metal with one slip surface with free cutting without a build-up on the front surface of the blade. Academic novelty is characterized by the developed algorithmic model which is based on the interrelation of shearing angles, external friction-slip chips on the front surface of the blade, internal friction-shear in the plane of shear and the front angle of the blade. The algorithmic model is implemented programmatically in the NI LabVIEW environment and graphically analytical in the KOMPAS-3D program. There were carried out computer experiments and identified the dependencies of chip formation angles on cutting speed and the front angle of the blade. The practical significance consists in the possibility to carry out an engineering analysis of the metal cutting mechanics without carrying out some valuable complex experiments.
Porous Structures and their Effect on Thermophysical Properties of Thermal Protection Elements
Authors: Pavlenko Anatolii , Cheilytko Andrii , Ilin Serhii Ilin , Koshlak Hanna
Published: May 2019

The improvement of the thermal insulating material thermophysical characteristics of the thermal protection elements by studying the porous structure is a promising direction of research. The article describes the effects of the porosity and coupling of the porous structure on the thermophysical characteristics of thermal insulating materials. The article uses standard systematized techniques and instruments of scientific research applied in thermophysics. The research methodology of highly-porous material thermophysical properties is based on performance of empirical laboratory investigations of the samples obtained. It was found that for the pore structure effect on the material characteristics it is rational to use the following complex indices: porosity, number of pores, pore position in space, the pore form, pore formation energy. The article shows the effect of the porous structure on the thermophysical characteristics of the material. The complex parameters of the porous structure, which will allow to develop a new method of control of the porous structure, are proposed. As a result of the experiment planning method, the regression equation of an effective coefficient of thermal conductivity for porous thermal protection structures was developed. It was established that for a more even distribution of the mixture in a volume it is necessary to minimize the size of the dispersed components, thereby increasing the area of their contacts. The experimental method revealed that the moisture evaporation caused the formation of pores inside the clay. The shape of the pores was determined using electron microscope MMP-2P, both on the sample section and surface. The clearest clay has the greatest porosity (no iron oxide and calcium oxide). The pores have a spherical shape in it. The presence of impurities reduces the material porosity due to the increased clay viscosity.

Authors: Kadek Rihendra Dantes
Published: May 2019

This study aimed to determine the influence of fiber volume fraction towards composite toughness and the composite hybrid fracture pattern models reinforced by hemp fiber and fiberglass to find out the ratio of composite toughness from variation of hemp fiber volume fraction and fiberglass A1 (15 : 25), A2 (20 : 20), A3 (25 : 15)%. This research is an experimental method research with the dependent variable is composite toughness and the independent variable is the fiber volume fraction. Based on the test and data analysis, the results for fraction A1 (15 : 25)% have the greatest impact absorption of 10834.6 J/m2 compared to A2 (20 :20)% that have absorption of 8470.828 J/m2 and A3 (25 : 15)% is 7168.813 J/m2. The most prominent one of the three variations of volume fractions on this fracture pattern analysis is the existence of (delamination) or there are fibers which are not perfectly exposed to the matrix. The Delamination usually occurs due to overly tightening of the fibers.

Published: May 2019

In the management of water resources, it is necessary to balance the demands of multiple uses of water and water availability, while enabling use in an environmentally sustainable way. Probability distributions of flow rates are essential tools for assessing water availability. The objectives of this work were to analyze the best probability distribution that conforms to the annual minimum daily average discharge for periods of seven consecutive days (Q7) for 14 stream gauging stations in the Das Velhas River Basin and to identify possible trends in Q7 time series and in bi monthly and annual sets of daily discharges in three key stream gauging stations. The quality of fit was verified by the Anderson-Darling test (A-D). The selection of the models that presented the best fit was done according to the Bayesian Information Criterion (BIC). The Mann-Kendall test was used to verify trends in time series of discharge. In general, better measures of quality of fit were obtained for the probability distributions Gumbel and Rayleigh. Negative trends in discharge distributions were verified in the three stations. For the Várzea da Palma station, the closest to the river mouth, negative and significant trends were found for the Q7 data and daily average discharge for every bimester except the first.
Corporations, human rights and the environmental degradation–corruption nexus
Authors: Huisman Wim , Sidoli Daniel
Published: May 2019

It is often the case that harms to societies go hand in hand. This seems to be true when looking at cases in which corporations are accused of contributing to human rights abuses, environmental degradation and corruption in developing nations. This article considers the relationships between these three harms from the perspective of corporations as actors involved in producing those harms. Based on a cross-case analysis of 45 cases in which this nexus of harms is found, this article assesses the atrocity crimes/environmental degradation/corruption-nexus, by studying agency (crime scripts), actors (industries and corporations) and connections (how are the three harms related?) in these cases. The analysis shows that corporations are mostly indirectly involved in atrocity crimes, but directly involved in environmental harm and corruption. Extractive industries are overrepresented and the many entanglements with state agents qualify as state-corporate crime. The relations between the harms are multifaceted and can be causal, spurious and synonymous by nature.
Listening to nature's voice: invasive species, Earth jurisprudence and compassionate conservation
Authors: Riley Sophie
Published: May 2019

Humanity's land management practices reconstruct nature by destroying and degrading habitats, species and ecosystems, and creating environmental imbalance. The latter can manifest in overabundant or invasive species, imposing a welfare burden on unwanted animals when they are targeted for eradication and control. Such approaches not only overlook animal wellbeing, but also ignore the role that humans have played in species’ classifications. As societies grapple to manage the unstable environments they have created, they have also started to realize that standards set by paradigms, such as sustainable development, do not sufficiently engage with the efficacy or ethics of existing practices. This article argues that a synthesis of law and science, drawn respectively from emerging paradigms, such as the Great Law of Earth jurisprudence and principles of compassionate conservation, can help guide environmental regimes towards more effective and ethical outcomes. From a legal perspective, the Great Law subordinates human law to a metaphorical nature's voice, while from a scientific perspective the scientific underpinnings of compassionate conservation identify that voice. Although compassionate conservation injects empathy into the decision-making processes, it is a form of empathy based on science that commences from the stipulation that regulators should first do no harm. It is a call that is specifically relevant to invasive species, where current regulation is based on harming certain species, while simultaneously overlooking environmental threats generated by humans. By using science to identify nature's voice, and law to listen to that voice, regulators can start to design regimes that work with nature, rather than trying to reconstruct and dominate it.

Abstract. Designing effective control policies requires efficient quantification of the nonlinear response of air pollution to emissions. However, neither the current observable indicators nor the current indicators based on response-surface modeling (RSM) can fulfill this requirement. Therefore, this study developed new observable RSM-based indicators and applied them to ambient fine particulate matter (PM2.5) and ozone (O3) pollution control in China. The performance of these observable indicators in predicting O3 and PM2.5 chemistry was compared with that of the current RSM-based indicators. H2O2 × HCHO/NO3 and total ammonia ratio, which exhibited the best performance among indicators, were proposed as new observable O3- and PM2.5-chemistry indicators, respectively. Strong correlations between RSM-based and traditional observable indicators suggested that a combination of ambient concentrations of certain chemical species can serve as an indicator to approximately quantify the response of O3 and PM2.5 to changes in precursor emissions. The observable RSM-based indicator for O3 (observable peak ratio) effectively captured the strong NOx-saturated regime in January and the NOx-limited regime in July, as well as the strong NOx-saturated regime in northern and eastern China and their key regions, including the Yangtze River Delta and Pearl River Delta. The observable RSM-based indicator for PM2.5 (observable flex ratio) also captured strong NH3-poor condition in January and NH3-rich condition in April and July, as well as NH3-rich in northern and eastern China and the Sichuan Basin. Moreover, analysis of these newly developed observable response indicators suggested that the simultaneous control of NH3 and NOx emissions produces greater benefits in provinces with higher PM2.5 exposure by up to 12 µg m−3 PM2.5 per 10 % NH3 reduction compared with NOx control only. Control of volatile organic compound (VOC) emissions by as much as 40 % of NOx controls is necessary to obtain the co-benefits of reducing both O3 and PM2.5 exposure at the national level when controlling NOx emissions. However, the VOC-to-NOx ratio required to maintain benefits varies significantly from 0 to 1.2 in different provinces, suggesting that a more localized control strategy should be designed for each province.

Abstract. Summer in the Arctic is the season when the sea ice covered ocean experiences rapid changes in its sea ice concentration, the surface albedo, and the melt pond fraction. These processes drastically affect the energy balance of the region and it is a challenge for climate models to represent those correctly. In this paper, the broadband albedo (300–3000 nm) of Arctic sea ice is derived from Medium Resolution Imaging Spectrometer (MERIS) optical swath data by transforming the spectral albedo as an output from the Melt Pond Detector (MPD) algorithm by a newly developed spectral-to-broadband conversion (STBC). The new STBC replaces the previously applied spectral averaging method to provide a more accurate broadband albedo product which approaches the accuracy of 0.02–0.05 required in climate simulations and allows a direct comparison to broadband albedo values from climate models. The STBC is derived empirically from spectral and broadband albedo measurements over landfast ice. It is validated on a variety of simultaneous spectral and broadband field measurements over Arctic sea ice, is compared to existing conversion techniques and shows a better performance than the currently published algorithms. The root mean square deviation (RMSD) between measured and broadband albedo converted by the STBC is 0.02. Other conversion techniques, the spectral averaging method and the linear combination of albedo values from four MERIS channels, achieve higher RMSDs of 0.09 and 0.05. The improved MERIS derived broadband albedo values are validated with airborne measurements. Results show a smaller RMSD of 0.04 for landfast ice than the RMSD of 0.07 for drifting ice. The MERIS derived broadband albedo is compared to broadband albedo from ERA5 reanalysis to examine the albedo parameterization used in ERA5. Both albedo products agree in the large-scale pattern. However, consistency in point-to-point comparison is rather poor, with correlations between 0.71 and 0.76 and RMSD in excess of 0.12. This suggests that the climatological sea ice albedo values used in ERA5 are not adequate and need revising, in order to better simulate surface heat fluxes in the Arctic. The advantage of the resulting broadband albedo data set from MERIS against other published data sets is the additional data set of melt pond fraction available from the same sensor. Melt ponds are the main reason for the sea ice albedo change in summer but currently are not represented in climate models. Additional information on melt evolution together with the accurate albedo product can aid the challenging representation of sea ice optical properties in summer in climate models.

La interpretación fenomenológica de la “triple síntesis” de Kant en Kant y el problema de la metafísica de Heidegger
Authors: Vargas Carlier Nicolás
Published: May 2019

El siguiente ensayo tiene como objetivo analizar la interpretación fenomenológica de Martin Heidegger de la función de la imaginación pura (o trascendental) en la triple síntesis de Immanuel Kant –según la primera edición de la Crítica de la razón pura. En la primera parte, revisaremos la triple síntesis en términos analíticos, con el fin de situar la función de la imaginación trascendental. En la segunda parte, discutiremos la interpretación específica de la imaginación trascendental en Kant y el problema de la Metafísica de Martin Heidegger. ¿Hasta qué punto la interpretación fenomenológica de Martin Heidegger contraviene los fundamentos de la filosofía trascendental?
