Radiocarbon Measurements of Ecosystem Respiration and Soil Pore-Space CO2 in Utqiaġvik (Barrow), Alaska
Authors: Vaughn Lydia J. S. , Torn Margaret S.
Published: April 2018

Abstract. Radiocarbon measurements of ecosystem respiration and soil pore space CO2 are useful for determining the sources of ecosystem respiration, identifying environmental controls on soil carbon cycling rates, and parameterizing and evaluating models. We measured flux rates and radiocarbon contents of ecosystem respiration, as well as radiocarbon in soil profile CO2 in Utqiaġvik (Barrow), Alaska, during the summers of 2012, 2013, and 2014. We found that radiocarbon in ecosystem respiration ranged from +60.5 to −160 ‰ with a median value of +23.3 ‰. Ecosystem respiration became more depleted in radiocarbon from summer to autumn, indicating increased decomposition of old soil organic carbon and/or decreased CO2 production from fast-cycling carbon pools. Across permafrost features, ecosystem respiration from high-centered polygons was depleted in radiocarbon relative to other polygon types. Radiocarbon content in soil pore-space CO2 varied between −7.1 and −280 ‰, becoming more negative with depth in individual soil profiles. These pore-space radiocarbon values correspond to CO2 mean ages of 410 to 3350 years, based on a steady-state, one-pool model. Together, these data indicate that soil respiration is derived primarily from old, slow-cycling carbon pools, but that total CO2 fluxes depend largely on autotrophic respiration and heterotrophic decomposition of fast-cycling carbon within the shallowest soil layers. The relative contributions of these different CO2 sources are highly variable across microtopographic features and time in the sampling season. The highly negative Δ14C values in soil pore-space CO2 and autumn ecosystem respiration indicate that when it is not frozen, very old soil carbon is vulnerable to decomposition. Radiocarbon data and associated CO2 flux and temperature data are stored in the data repository of the Next Generation Ecosystem Experiments (NGEE-Arctic) at http://dx.doi.org/10.5440/1364062.
Autonomous micro-platform for multisensors with an advanced power management unit (PMU)
Authors: Bellier Pierre , Laurent Philippe , Stoukatch Serguei , Dupont François , Joris Laura , Kraft Michael
Published: April 2018

Abstract. In this work, we developed and characterised an
autonomous micro-platform including several types of sensors, an advanced
power management unit (PMU) and radio frequency (RF) transmission capabilities. Autonomy
requires integration of an energy harvester, an energy storage device, a
PMU, ultra-low-power components (including sensors) and optimized software.
Our choice was to use commercial off-the-shelf components with low-power
consumption, low cost and compactness as selection criteria. For the
multi-purpose micro-platform, we choose to include the most common sensors
(such as temperature, humidity, luminosity, acceleration, etc.) and to
integrate them in one miniaturised autonomous device. A processing unit is embedded in the system. It allows for data acquisition from
each sensor individually, simple data processing, and storing and/or
wireless data transmission. Such a system can be used as stand-alone, with
an internal storage in a non-volatile memory, or as a node in a wireless
network, with bi-directional communication with a hub device where data
can be analysed further. According to specific application requirements,
system settings can be adjusted, such as the sampling rate, the resolution and the
processing of the sensor data. Parallel to full autonomous functionality, the low-power design enables us to
power the system by a small battery leading to a high degree of autonomy at a high
sampling rate. Therefore, we also developed an alternative battery-powered
version of the micro-platform that increases the range of applications. As
such, the system is highly versatile and due to its reduced dimensions, it
can be used nearly everywhere. Typical applications include the Internet of
Things, Industry 4.0, home automation and building structural health monitoring.
State fusion entropy for continuous and site-specific analysis of landslide stability changing regularities
Authors: Liu Yong , Qin Zhimeng , Hu Baodan , Feng Shuai
Published: April 2018

Abstract. Stability analysis is of great significance to landslide hazard prevention, especially the dynamic stability. However, many existing stability analysis methods are difficult to analyse the continuous landslide stability and its changing regularities in a uniform criterion due to the unique landslide geological conditions. Based on the relationship between displacement monitoring data, deformation states and landslide stability, a state fusion entropy method is herein proposed to derive landslide instability through a comprehensive multi-attribute entropy analysis of deformation states, which are defined by a proposed joint clustering method combining K-means and a cloud model. Taking Xintan landslide as the detailed case study, cumulative state fusion entropy presents an obvious increasing trend after the landslide entered accelerative deformation stage and historical maxima match highly with landslide macroscopic deformation behaviours in key time nodes. Reasonable results are also obtained in its application to several other landslides in the Three Gorges Reservoir in China. Combined with field survey, state fusion entropy may serve for assessing landslide stability and judging landslide evolutionary stages.
Changes in flow of Crosson and Dotson ice shelves, West Antarctica, in response to elevated melt
Authors: Lilien David A. , Joughin Ian , Smith Benjamin , Shean David E.
Published: April 2018

Abstract. Crosson and Dotson ice shelves are two of the most rapidly changing outlets in West Antarctica, displaying both significant thinning and grounding-line retreat in recent decades. We used remotely sensed measurements of velocity and ice geometry to investigate the processes controlling their changes in speed and grounding-line position over the past 20 years. We combined these observations with inverse modeling of the viscosity of the ice shelves to understand how weakening of the shelves affected this speedup. These ice shelves have lost mass continuously since the 1990s, and we find that this loss results from increasing melt beneath both shelves and the increasing speed of Crosson. High melt rates persisted over the period covered by our observations (1996–2014), with the highest rates beneath areas that ungrounded during this time. Grounding-line flux exceeded basin-wide accumulation by about a factor of 2 throughout the study period, consistent with earlier studies, resulting in significant loss of grounded as well as floating ice. The near doubling of Crosson's speed in some areas during this time is likely the result of weakening of its margins and retreat of its grounding line. This speedup contrasts with Dotson, which has maintained its speed despite increasingly high melt rates near its grounding line, likely a result of the sustained competency of the shelf. Our results indicate that changes to melt rates began before 1996 and suggest that observed increases in melt in the 2000s compounded an ongoing retreat of this system. Advection of a channel along Dotson, as well as the grounding-line position of Kohler Glacier, suggests that Dotson experienced a change in flow around the 1970s, which may be the initial cause of its continuing retreat.
Paranoid Poetics: Prisoners of Words in the Absurd Theater of Adamov
Authors: Woodward Servanne
Published: April 2018

Adamov’s plays reflect language’s degradation and the state of anxiety it provokes in modern civilization, he incoherent state of the modern Verb, imparted by the disappearance of God. Linguistic disorder then springs from random referents: praying to God, as Adamov attempted to do for a while, becomes absurd in front of an empty sky. In the absence of the Verb language’s link to the Creation, or truth in writing, do not exist. All that remains is a codified, systematized language, which, like the machine central to Ping-Pong, does not function in a reliable consistent manner. Eventually, Adamov will dare call things by their name, using proper French conventional designations of language as everyone’s language as opposed to private or floating symbolism when he feels anchored or “rooted” in France.
Procesamiento semántico de conceptos concretos y abstractos en Afasia Progresiva Primaria-variante semántica
Authors: Martínez-Cuitiño Macarena , Soriano Federico , Formoso Jesica , Borovinsky Geraldine , Ferrari Jesica , Pontello Noelia , Barreyro Juan Pablo , Manes Facundo
Published: April 2018

La Afasia Progresiva Primaria-variante semántica (APP-vs) se caracteriza por la afectación progresiva del conocimiento conceptual. Algunas investigaciones han reportado la mayor afectación de los conceptos abstractos en relación con los concretos, es decir, un efecto de concretud. No obstante, otros investigadores dan cuenta de un efecto de concretud inverso, es decir, un mejor desempeño con conceptos abstractos en relación con concretos. En esta investigación se compara el desempeño, por medio en una tarea de juicios de sinonimia, de un grupo de 8 pacientes diagnosticados con APP-vs y un grupo de 20 controles emparejados en edad y nivel educativo. Los resultados dan cuenta de un efecto de concretud, es decir, un mejor desempeño con conceptos concretos tanto con sustantivos como con verbos. Estos hallazgos se alinean con las investigaciones previas en las que se detecta un peor rendimiento de los pacientes con APP-vs con conceptos abstractos. El efecto de concretud encontrado apoyaría la hipótesis de un centro semántico amodal relevante para el procesamiento de conceptos concretos y abstractos. La menor afectación de los conceptos concretos observada podría explicarse por su mayor riqueza semántica.
Diversity Management in Organisations Located within the Visegrad Group V4 Countries (The Czech Republic, Poland, Slovakia and Hungary) – State of Implementation and Benefits
Authors: Gross-Gołacka Elwira
Published: April 2018

The goal of this article is to determine the state of implementation of the concept of diversity management in organisations within countries belonging to the Visegrad Group V4 and gather opinions regarding if and (if so) what benefits result from implementing this concept. For the purposes of the research, the literature on the topic was reviewed and a diagnostic survey was conducted, which was based on a survey questionnaire. Empiric research was conducted in the years 2015-2016 on a test group of 401 representatives from organisations in the Visegrad Group (Poland, the Czech Republic, Slovakia, Hungary). These were qualitative-quantitative studies. According to the research, the level of implementing diversity management in the organisations examined is low, despite the fact that the representatives saw its benefits and declared their intent to seek more knowledge on this topic. Unequal treatment and discrimination, according to the respondents, occurs most frequently due to age, and at a further stage, due to gender and ethnic origin. The research has shown that according to the opinion of the respondents from the organisations, diversity management carries a multitude of benefits.

Authors: Abou Hashish Ebtsam Aly , Abdel All Neveen Hassan , Mousa Amal Awad
Published: April 2018

Background and objective: Psychological empowerment and work engagement are vital factors to consider when managing changes in workplace and enhancing both individual and overall organizational performance and increasing nurses’ job security. This study aimed to explore how nurses perceive their psychological empowerment, work engagement, and job insecurity. Further, to investigate whether nurses’ perception of psychological empowerment is related to their work engagement and job insecurity.Methods: A descriptive correlational research design was conducted using a convenience sample of nurses (N = 400) working in Damanhur educational hospital, Egypt. Psychological Empowerment Questionnaire, Utrecht Work Engagement Scale, and Job Insecurity Inventory proved valid and reliable to measure study variables.Results: The present study revealed that nurses experienced high psychological empowerment and work engagement and perceive a lower level of job insecurity. A significant positive correlation was found between nurses’ perception of psychological empowerment and their work engagement. On the contrary, Job Insecurity was negatively correlated with each of psychological empowerment and work engagement (p < .001). In addition, psychological empowerment and work engagement can significantly predict 6.6%, and 9.3% of job insecurity respectively where the regression model is significant (p < .001).Conclusions: Nurses perceived their work environment as empowering and their work as challenging and stimulating, rending their competence, so they psychologically attached to and engaged in work and feel less job insecurity. Recommendations: Creating an atmosphere of trust and empowering nurses psychologically is inevitable. Hospital managers can adopt strategies that facilitate nurses’ engagement and reduce the levels of job insecurity. Positive empowering work climate, social support, and nurse managers leadership styles are factors that foster work engagement and job security.

A good analysis of the success factors in the university entrance exam, which is an important step for academiccareers of students, is believed to help them manage this process. Properties such as self-regulation and learningapproaches adopted by students undoubtedly influence their academic achievement as well as their success inuniversity entrance exams. However, it is not exactly known how the direct and indirect relations between thesevariables are, and which variable has more effect on success. This research aims to determine the extent to whichuniversity entrance exam score as dependant variable; and academic achievement, deep, surface and strategiclearning approaches, four sub-dimensions of self-regulatory learning skills scale as independent variables to predictuniversity entrance exam score directly and indirectly; to this end, a path model was developed. Within the scope ofthe research, the data obtained from 445 students in the 4th class of the state-affiliated high schools in the 2016-2017academic year were used. As a result of the research, the most important factor affecting the success of universityentrance exam was found to be diploma grade; while diploma grades raise by using deep learning approaches, theyfall by using surface learning approaches. It was detected that the use of the strategic learning approach reducesuniversity entrance exam scores.

The main purpose of this research study is to explore perceived risk influence on brand made in Ghana consumer decision making towards non-perishable products category. The study is particularly positioned to advance knowledge in the theories of buyer behaviour pertaining to the purchase consumer decision model (EKB model – Engel, Kollet, Blackwell). The key variables investigated include performance risk, financial risk, physical risk, and social risk. A sample of 206 respondents was employed using convenient selection method. A self-completed 5 point Likert structured questionnaire survey was the data collection instrument used. The data collected were computed and analysed by linear regression to determine significant influence of the variables involved in this study. Overall results of the perceived risk variables showed that only performance risk was found significant influence on brand made in Ghana consumer decision making towards non-perishable products category. Among the variables that are rejected with no significant influence on brand made in Ghana decisions includes financial risk, physical risk, and social risk. It is recommended that manufacturers and policy makers develop more pragmatic and practical integrated approach supported by policy document in order to sensitise minds of consumers towards brand made in Ghana.

Published: April 2018

Organizational Commitment indicates the degree to which HRM practices are able to cultivate emotional connection between firms and employee goals.  This study sought to investigate the nature of the relationship between the implementation of HRM practices and organizational commitment in the banking industry in Ghana.  Employing the three component model of Allen and Meyer as the underlying theory of organizational commitment, the researchers examined the six HRM practices in five selected commercial banks in Ghana.  Adopting the quantitative method of research, a descriptive including a multiple regression analysis was used to analyze the existing relationship between the HRM practices and organizational commitment.  Findings from the study revealed that affective and normative forms of commitment were preferred to continuance forms of commitment. Again whilst respondent’s affective and normative commitment included performance based pay, communication and information sharing, training and development and rewards recognition, that of the continuance commitment also included communication, information sharing, recruitment and selection performance appraisal as well as rewards and recognition. The study concludes that there is a positive relationship between the implementation of HRM practices and organizational commitment. A further study is therefore suggested towards the conduct of a qualitative study in all banks in Ghana to consider the applicability of generalizability on the subject matter.
Critical Success Factors That Influence Black Leadership Integration in Companies Listed on the Johannesburg Securities Exchange

Published: April 2018

In the context of post-apartheid period, there have been certain measures introduced to have employment equity in South Africa. The integration of black leadership in a white dominant companies was one among them. The purpose of this study is to identify the critical success factors that influence black leadership integration as per the reform measures defined after post-apartheid period in South Africa. The overall research question guiding this study is: What are the critical success factors that influence black leadership integration in companies listed on the Johannesburg Securities Exchange? The quantitative correlation research design utilizes a pre-validated survey to access the success factors that influence black leadership integration. To address the research question, the independent variables – corporate culture, leadership style, diversity and strategic leadership behaviours – were correlated with three dependent variables - tenure (years of service), job satisfaction and growth satisfaction (career development opportunities) as measures of successful leadership integration. The study finds statistically significant relationships amongst many of the 32 constructs identified in the literature which using factor analysis are described as fair treatment, job hopping, commitment to transformation, Black entrepreneurship and corporate culture. As defined by Black management, job satisfaction, career development (dependent variables), fair treatment and specific leaders behaviours (inspirational motivation and idealised attributes) (independent variables) as defined by MLQ 5X leadership survey are critical success measures that could influence Black leadership integration in Johannesburg Securities Exchange (JSE) listed companies. The results of this study provide strong evidence of critical success factors that have a statistically significant influence on successful Black leadership integration into historically White dominated South African companies.

Published: April 2018

Producing high quality forage and maintaining productive pastures is a major challenge that beef producers encounter, as rejuvenation is a complex and costly challenge. This is part of a series of papers looking at potential options and methods of rejuvenation to improve the productivity of older forage stands in northern Alberta. The methods of rejuvenation investigated were sub-soiling, break & re-seeding, a combination of manure application plus subsoiling, high stock density grazing, bale grazing, pasture rest, as well as direct seeding in spring and fall. In this series, forage dry matter (DM) yield, forage nutritive value and economic performance are presented and discussed. The top 5 forage DM yielders were bale grazing, manure + subsoil in fall, break & re-seeding, high stock density grazing and fertilizer application in that order. In both years, bale grazing consistently produced higher forage DM yield than other methods including control, with bale grazing giving up to 100% higher yield at site-1 and 219% at site- 2 for the 2-year total forage DM. Most forage nutritive value parameters measured were similar for the rejuvenation methods investigated. A simplified economic analysis done in this study showed that the direct input cost of rejuvenation an old forage stand was higher with the break & re-seeding method than other methods. However, for bale grazing, when the cost of hay bales used was factored in, then the cost of bale grazing far exceeded those of other methods including break & re-seeding. The implications of the results obtained in this study in relation to beef cattle production system are highlighted.

Published: April 2018

In other countries, they usually use auto road and railroad as borders of the forest seed regions. In case of Mongolia, this method is not suitable since sparse population, large distribution area of forests and large territory. Therefore, we used topographical features to determine borders of the seed regions. Satellite images in combination with DEM make it possible to define rivers, streams and mountain ridges as border of forest seed regions. Species included in forest seed regions are: Siberian larch (Larix sibirica Ldb.), Dahurian larch (Larix dahurica Turcz), Chekanovskii larch (Larix chekanowski Szaf.), Scotch pine (Pinus sylvestris L.), Siberian pine (Pinus sibirica Du Tour.), Siberian spruce (Picea obovate Ldb.), and Siberian fir (Abies sibirica Ldb.).Mongolian forests are mountain forests with high altitudinal variation and have dry growth condition hence, seed quality of the main tree species is declining recently. It is required to use seeds from the same seed region. Only if this is not possible the seeds should be obtained from regions with comparable ecological conditions.Local seed is the ones collected from the forests within the border of same seed region, and seed from the other regions are the ones collected from the other seed region. Seeds collected from the plain forests can be used for almost all forest regions, however seeds collected from mountainous regions can only be used within 200-400 m limit of the original altitude.We identified 19 seed regions for Siberian larch and 12 regions for Scots pine, 9 regions for Siberian pine, 6 regions for Siberian fir and 9 seed regions for Siberian spruce forests, respectively. Due to lack of genetic-selection study in Mongolia, this proposed forest seed regions can be considered as preliminary effort and it is possible to changed and improved based on more detailed research results. These forest seed regions proposed by project team can be used as fundamental material for establishing permanent forest seed supply based on genetic-selection characteristics of the forests in different regions in Mongolia.

Published: April 2018

In this study, PM2.5 pollution of indoor and outdoor ambience has been measured on a household which is located between the Ger area and the residential district at simultaneous duration and point. In order to analyze, we used n = 3,119,500 data which was measured at each 10 second during 24 hours period. The instrument that was used to study, created by Nagoya University and Panasonic Corporation. In recent years, the capital of Ulaanbaatar, Mongolia, is leading the air pollution during the winter in the world, and the majority of this pollution is comprised of PM2.5 . Fine particles are very harmful to human health, and people spend approximately 90% of their lives in the indoor ambient. Thus, it is important to measure continuously the amount of indoor and outdoor PM2.5, so we have selected two points and indicated some statistical analysis on indoor and outdoor ambient. The results of this study indicate the PM2.5 concentrations of air in Ulaanbaatar are higher than the air quality standard in October and peak in the December and January. Also, due to the feature of the sites being measured, pollution of indoor ambient was demonsrated strong or weak level, which is depended on outdoor ambient pollution. The measurements of the majority days were a high level of pollution from at 00:00 to 04:00 pm, however, it was decreased at 5:00 pm, but it started to increase around 07:00 to 09:00 in the morning, and it decreased from 10:00 am to low level of the pollution whole day. At 18 o’clock in the evening, the pollution was increasing and at the peak of the day, the fine particle pollution up to 02:00 on the next day.
Parents’ temporal perspective and their economical education practice

Published: April 2018

Previous studies have shown that economical behaviours among the adults depend on temporal perspective they take. Taking this into account, it was predicted that temporal perspective can play an important role also when explaining different economic education practices employed by the partents when educating their childrem. The aim of the current study was to look at the relationship between temporal perspectivs of the parents and their strategies of economic education of their children. In this survey study 108 parents of children aged between 10 and 12 years old took part (755 mothers and 33 fathers). The results
showed that future-negative perspective is connected with a later onset of economic education of the child, whereas future and
present-hedonistic perspectives are related to an earlier onset of economic education of the children. It should be noted, however, that the applied practices of economic education are different among people with a strong future perspective and present-hedonistic perspective.
Individual traits and a tendency to procrastinate among students
Authors: Paszkowska-Rogacz Joanna , Poraj Grażyna
Published: April 2018

Systematic psychological studies of procrastination started quite recently – in the late eighties. Scientists suggest that procrastination concerns many people, most often, however, it occurs among students. The percentage of affected reaches 70–95%. Despite that, not many studies looking at Polish students have been carried out. The aim of the current study was to analyze a relationship between chosen individual characteristics (personality traits), self-esteem, self-efficiency and procrastination among students. The experiment used: Procrastination Questionnaire, Personality Inventory (NEO-FFI), Self-Assessment Scale and a Generalised Effectiveness Scale. 140 participants were empoloyed (75 females and 65 males). No gender difference in terms of procrastination was found. The most important predictive factor of procrastination was conscientiousness. Other important factors were time management and being systematic, strong will, the awareness of procrastination, procrastination as a trait, and a lack of punctuality. Weak predictors, significant only for some scales measuring procrastination, were: extroversion, neuroticism, openness, self-esteem and self-efficiency. The research, however, needs a continuation, because procrastination can lead to serious problems.
Philosophical questions about time
Authors: Janowski Jarosław Maciej
Published: April 2018

The article aims to show an important role of time on philosophical grounds. At the same time, difficulties present in philosophical discourse are shown, when one tries to describe and understand a phenomenon of time. In philosophical
studies on time, specific questions can be distinguished. This leads to three facets (ontological, psychological, and pistemological)
when studying time. These facets are the most basic aspects in which the „time phenomenon” can be seen. Detailing of the studies in the ontological framework allows a creation of its typology. Helpful in doing that are ontological categories of things (substances), events, processes, as well as a new ontological category – in which human becomes an ontical basis of the world. Finally, typology of the ways of describing time because of its ontological status forms a continuum with three characteristic points: 1) realism, 2) arealism, 3) a broad borderline between realism and arealism.
Specifics of religiocity and temporal perspectives by Philip Zimbardo and John Boyd.
Authors: Kłakulak-Torba Weronika
Published: April 2018

Religiocity, being an immanent part of an individual’s personality, influences numerous aspects of psychological functioning. One of them is a temporal dimension of human existence. Being a member of a religious community in times of growing secularity encourages a reflection on motivation and specifics of religiosity of people engaged. The aim of current work is to verify the relationship between religiosity and temporal perspectives and to characterize the religiosity of young Catholics belonging to the three most popular in Poland religious communities. There were 172 participants. They filled in a questionnaire „Your religiosity”, measuring religious orientations or a „Religion Centralism” scale, which describes religion in five dimensions. Every participant also filled in a time perspective questionnaire. The analysis revealed a negative correlation between past-negative tmeporal perspective and religious engagement. An unexpected result was a positive correlation between a social aspect of religious orientation and transcendental future. Additionally, religion centralism correlated negatively with a deviant factor of temporal perspective balance. Based on the obtained results it can be suggested that among all temporal perspectives, the qualitative interpretation of one’s own past has the biggest influence on religious engagement. Another conclusion is that an important factor of religious activity is a possibility of meeting affiliation needs. Conducted analysis also allowed conclusions on the specifics of the religiosity of young Catholics.

Published: April 2018

Though synthetic organic colorants are used in various applications nowadays, there is the concern that impurities by-produced during the manufacturing and degradation products in some of these colorants are persistent organic pollutants and carcinogens. Thus, it is important to identify the synthetic organic colorants in various products, such as commercial paints, ink, cosmetics, food, textile, and plastics. Dyes, which are soluble in water and other solvents, could be analyzed by chromatographic methods. In contrast, it is difficult to analyze synthetic organic pigments by these methods because of their insolubility. This review is an overview of mass spectrometric analysis of synthetic organic pigments by various ionization methods. We highlight a recent study of textile samples by atmospheric pressure solid analysis probe MS. Furthermore, the mass spectral features of synthetic organic pigments and their separation from other components such as paint media and plasticizers are discussed.

While color is arguably the most important optical property of evidential fibers, the actual dyestuffs responsible for its expression in them are, in forensic trace evidence examinations, rarely analyzed and still less often identified. This is due, primarily, to the exceedingly small quantities of dye present in a single fiber as well as to the fact that dye identification is a challenging analytical problem, even when large quantities are available for analysis. Among the practical reasons for this are the wide range of dyestuffs available (and the even larger number of trade names), the low total concentration of dyes in the finished product, the limited amount of sample typically available for analysis in forensic cases, and the complexity of the dye mixtures that may exist within a single fiber. Literature on the topic of dye analysis is often limited to a specific method, subset of dyestuffs, or an approach that is not applicable given the constraints of a forensic analysis. Here, we present a generalized approach to dye identification that (1) combines several robust analytical methods, (2) is broadly applicable to a wide range of dye chemistries, application classes, and fiber types, and (3) can be scaled down to forensic casework-sized samples. The approach is based on the development of a reference collection of 300 commercially relevant textile dyes that have been characterized by a variety of microanalytical methods (HPTLC, Raman microspectroscopy, infrared microspectroscopy, UV-Vis spectroscopy, and visible microspectrophotometry). Although there is no single approach that is applicable to all dyes on every type of fiber, a combination of these analytical methods has been applied using a reproducible approach that permits the use of reference libraries to constrain the identity of and, in many cases, identify the dye (or dyes) present in a textile fiber sample.
A Insularidade cabo verdiana além da questão geográfica e a emigração como consequência representada na arte
Authors: Pita André Laender
Published: April 2018

A insularidade cabo verdiana é um tema recorrente em estudos relacionados à história, economia e, inclusive, à arte do país. A pequena nação africana, resultado de um longo período de colonização portuguesa, apresenta características diferenciadas em relação aos outros territórios que tiveram ocupação semelhante e, por isso, o termo insularidade acabou sendo amplamente utilizado como sendo parte da cultura cabo verdiana. Este trabalho faz uma análise da questão insular no Estado de Cabo Verde como um fator geográfico, as implicações que o conceito tem além da geografia e como isso resulta na intensa emigração, fato já característico da população cabo verdiana. Por fim, apresenta representações artísticas da emigração como resultado da insularidade, nomeadamente na obra de Kiki Lima, artista plástico cabo verdiano residente em Portugal.

Published: April 2018

O artigo aborda a questão das aquisições transnacionais de terra que se expandiram e ganharam visibilidade a partir de 2008, no contexto das crises alimentar, financeira e energética que eclodiram no biênio 2007-2008. O objetivo deste texto é fornecer uma síntese dos processos de apropriação de terras nos últimos anos, destacando (i) as motivações por trás da recente onda de aquisições de terra; (ii) a dimensão do fenômeno e os principais setores de investimento; (iii) os principais países investidores e receptores; (iv) os instrumentos de governança global desenhados para a regulamentação dos land grabs; e (v) os principais atores envolvidos no processo nos níveis global, nacional e local. Assim, busca-se contribuir para a área das Relações Internacionais e para a subárea da Economia Política Internacional divulgando uma linha de pesquisa multidisciplinar e de grande relevância social. Para tanto, foi realizada uma revisão bibliográfica e documental, ancorada nas informações colhidas na base de dados Land Matrix e nas publicações especializadas.
Apresentação do Dossiê – Aquisição Transnacional de Terras (Land Grabbing)
Authors: Leite Alexandre Cesar Cunha , Lima Thiago
Published: April 2018

O movimento global de aquisições transnacionais de terra – também referenciado na literatura como land grabbing, land rush, acarapamiento e estrangeirização de terras – é um tema que ganhou atenção desde a crise alimentar de 2007/08. Milhões de hectares têm sido negociados em âmbito doméstico e internacionalmente, utilizando-se de mecanismos diversos, tomando formas novas e tendo motivações de origem variada, gerando, na maioria dos casos, efeitos sociais e ambientais negativos.
Uma relação entre a concepção artística da obra poética de Edgar Allan Poe e a teoria de polissistemas
Authors: Brito Pedro Alves de Oliveira
Published: April 2018

O ato tradutório, envolto em extensa gama de preconceitos, continua sendo visto como prática invisível, inescapavelmente presente, mas raramente reconhecida. Sabe-se, no entanto, que, através da tradução, o tradutor não está simplesmente interpretando um texto na língua original, em seguida produzindo um texto correspondente na língua alvo. Ao nos aprofundarmos no tema, percebe-se que o conceito de tradução poética se vê obrigado a distanciar-se de outros que, de forma semelhante, estejam ligados à tradução literária. Com base nessas considerações, o trabalho apresenta, utilizando como pilar a teoria de polissistemas de Itamar Even-Zohar, a concepção artística da poesia de Edgar Allan Poe, bem como os elementos teórico e literário presentes no potencial tradutório de sua obra. Palavras-chave: Literatura comparada. Edgar Allan Poe. Teoria de polissistemas.
TECHNOLOGICAL ASPECT OF PRODUCTION AND USE OF OIL-OLIGOMERIC ADDITIVE ON BASIS OF SECONDARY OLIGOMERS IN PRODUCTION OF EMULSION RUBBER

The paper shows the perspective direction of using by-products and wastes of the petrochemical industry in the production of rubber products. It was revealed that oligomers synthesized from petrochemical by-products can be used as promising additives. The technological aspects of the use of additives based on PN-6 oil and its combination with an oligomer synthesized from by-products of polybutadiene production in the technology of obtaining filled emulsion rubbers were studied. It has been found that the best way to combine oligomeric additives with the matrix of synthetic rubbers is to introduce them into latex in the form of dispersions. The influence of coagulants of different nature on the process of emulsion rubber release filled with oil oligomeric anthioxidant dispersion was investigated. It was found that the change in the mass ratio of oil-oligomeric-anthioxidant dispersion components did not significantly affect the consumption of the coagulant used. It has been shown that the introduction of an oil-oligomeric-anthioxidant additive into the elastomeric compositions at the stage of their creation provides an even distribution of the components in the rubber matrix. The effect of manufactured additives on the properties of the resulting composites was estimated. It has been found that vulcanizates obtained on the basis of rubber with a high content of oligomeric component in the composition of the additive have a higher resistance to thermal oxidative aging. Increasing the stability of vulcanizates to the thermal and oxidative effects indicates a decrease in the losses of the antioxidant in the process of obtaining rubbers and elastomeric compositions. It is shown that the introduction of oily oligomerically antioxidant dispersion in latex at the stage of creation of elastomeric compositions makes it possible to improve the technical and economic efficiency and environmental friendliness of their production. Evaluation of the effect of manufactured oligomeric additives on the properties of the resulting composites revealed their multifunctionality.Forcitation:Pugacheva I.N., Nikulina N.S., Nikulin S.S.
