ABSTRACT The aim of this study was to investigate the synergistic effect between inoculation with Azospirillum brasilense and nitrogen application, thus enabling a higher efficiency of nitrogen fertilization, as evaluated by nutritional value, components production, and grain yield of irrigated corn. The experiment was conducted in Selvíria, MS, Brazil, under a no-till system, on an Oxisol in the Brazilian Cerrado. The experiment was set up in a randomized block design with four replications, in a 4 × 2 factorial arrangement: four patterns of nitrogen application [application of 30 kg ha-1 of N at sowing and 150 kg ha-1 as cover (30 + 150); 30 kg ha-1 of N at sowing, split into two applications of 75 kg ha-1 as cover (30 + 75 + 75); 180 kg ha-1 of N at sowing (180); and 150 kg ha-1 of N at sowing and 30 kg ha-1 as cover (150 + 30)]; with and without inoculation of the seeds with A. brasilense. The application of 30 kg ha-1 of N at sowing and a single application of 150 kg ha-1 or two applications of 75 kg ha-1 in topdressing, inoculated with Azospirillum brasilense provided better nutrition and development, with a positive reflection on irrigated corn grain yield in the Brazilian Cerrado.

ABSTRACT The dual-stage sugar substitution technique (D3S) was used to induce sugar replacement in mango. It involved two stages, in which high-calorie sugars were partially removed from the fruit samples in the first stage and, in the second one, low-calorie sugar was incorporated into the mango. Ultrasonic waves can be applied in one or both stages and their use was also evaluated in this study. Results showed that submitting samples to ultrasonic waves (25 kHz) in both stages and their immersion in Stevia-based solution (250 or 500 g kg-1) in the second stage for 10, 20 and 30 min of processing gave higher water loss during the process, while greater solids gain could be achieved by applying ultrasound only in the first stage. Samples were also evaluated in terms of some quality parameters. The use of this technique resulted in samples with higher values of total phenolic content and changes in color parameters (L*, a* and b*). When samples were subjected to ultrasonic waves in both stages, a higher carotenoid retention was observed.

ABSTRACT Innovative techniques that seek to minimize the costs of production and the laboriousness of certain operations are one of the great challenges in the sugar-energy sector nowadays. Thus, the objective of the present study was to estimate the Pol values of sugarcane juice as a function of °Brix and wet cake weight (WCW) using artificial neural network (ANN) modeling. A database was organized consisting of 204 technological analyses from a field experiment with 15 treatments and 2 years of evaluation. 75% of the data were used for the calibration of the model and 25% for its validation. Multilayer Perceptron ANNs were used for calibration and validation of the data. Before calibration, the variables were normalized. The training algorithm used was backpropagation and the activation function was the sigmoid. The ANNs were established with two hidden layers and the number of neurons ranging from 4 to 20 in each. The 15 ANNs with the lowest root mean square errors were randomly presented by the software, among which 6 were chosen to verify the accuracy. The ANNs had a high accuracy in the estimation of sugarcane juice Pol, both in the calibration phase (R2 = 0.948, RMSE = 0.36%) and in the validation (R2 = 0.878, RMSE = 0.41%), and can replace the standard method of analysis. Simpler networks can be trained to have the same accuracy as more complex networks.

ABSTRACT In semi-arid regions, there is a high evaporation, which leads to soil dryness, interfering in the availability of water in the soil. Usually it is difficult to measure and model the evaporation due to the complexity of the available methods, the low soil water content and the low concentration of water vapor in the air. This can also make it difficult to monitor and simulate the evapotranspiration in these regions. Thus, the Portable Chamber method is used to directly measure evaporation and evapotranspiration, because this technique allows real time estimation and in short time intervals, giving a more detailed estimation of those processes. The objective of this study was to evaluate the evaporation through the mass transfer in the soil in an underground dam under different water table depths and conditions of the semi-arid environment of Pernambuco State in Brazil, through the values predicted by the SiSPAT model and measured by the portable chamber method. For the purposing of modeling and also to better know the soil behavior, soil hydraulic properties were determined though the Beerkan method. The portable chamber method was applied for one of the first times in a semi-arid region of Northeastern Brazil, and it was consistent with the potential evaporation of bare soil, reaching about 1,800 mm per year. The SiSPAT model was quite satisfactory for simulation of soil evaporation in different conditions of the water table depth. The values found for soil evaporation with the simulation of the SiSPAT and the Portable Chamber (PC) method differed in 1.43% and 4.44% for cases where the water table was at 0.20 and 1.20m of depth, respectively.

Abstract Animals reared in restricted environments are highly susceptible to gastrointestinal infection by helminths and protozoa and therefore zoos are characterized as being parasite-rich environments. Successful implementation of control programs of these parasites in zoo environment depends upon precise and rapid diagnosing of gastrointestinal infections. The aim of this study was to demonstrate the role of the Mini-FLOTAC technique in combination with Fill-FLOTAC for rapidly diagnosing parasitic infections in zoo mammals. Fecal samples were collected from 70 animals in four different zoos located in central and southern Italy. All the samples were analyzed using Mini-FLOTAC in combination with Fill-FLOTAC. Out of the 70 pooled samples examined, 80% (24/30) were positive for at least one parasite. Among the gastrointestinal nematodes, Strongyles were the most frequent (40%), followed by Trichuris spp. (23.3%), Parascaris spp. (13.3%) and Capillaria spp. (3.3%). Among the protozoa, Blastocystis spp., Giardia spp. and Eimeria spp. were detected in 6.6%, 3.3% and 3.3%, respectively. These results show that Mini-FLOTAC in combination with Fill-FLOTAC can be used, not only for rapidly diagnosing parasitic infections in zoo mammals, but also for monitoring control programs in which large numbers of fecal samples need to be examined rapidly and reliably.

Published: February 2019

Abstract Enterocytozoon bieneusi is an opportunistic intestinal pathogen that infects humans and a wide variety of animals worldwide. Our aim in this study was to investigate the occurrence of E. bieneusi in a domestic cat population in Campo Grande, Mato Grosso do Sul, Brazil. Sixty fecal samples from diarrheic cats were subjected to polymerase chain reaction (PCR) and the amplicons were sequenced for identification. E. bieneusi was detected in two samples (3.3%), both identified as genotype D. This genotype has already been reported in animals and humans and is considered a zoonotic genotype. Our findings represent the first report of E. bieneusi in domestic cats in Brazil, reinforcing the importance of identifying this agent as a source of infection in animals and humans.

Published: February 2019

Activated carbon fibre (ACF) was modified through the sulfuric acid impregnation method and used as an adsorbent for chlortetracycline (CTC) in mariculture wastewater. The modified ACF was characterised by scanning electron microscopy, Fourier transform infrared spectroscopy and Brunauer–Emmett–Teller area analysis. Six factors (namely, modification time, dosage of ACF, initial concentration of CTC, adsorption time, pH value and interfering ion) were screened to study their effects on the adsorption of CTC. A full 16-factorial design was employed for optimising the adsorption process. The removal rate of CTC reached 96% under optimal conditions: modification time of ACF of 60 min, pH value of 6, dosage of modified ACF of 0·04 g, reaction time of 4 h and initial concentration of CTC of 20 mg/l. The dosage of modified ACF had the most positive effect on CTC. The adsorption kinetics favoured the pseudo-second-order model. The isotherm favoured the Langmuir model with the maximum adsorption capacity of 87 mg/g. The present work showed that the modified ACF is an effective adsorbent for the removal of CTC from mariculture wastewater.
Stochastic analysis of the capacity of two parallel footings on a thin sand layer

Published: February 2019

This paper presents a study on the stochastic bearing capacity of two parallel strip footings supported on a heterogeneous sand layer confined by a rigid base. Variability of the sand is represented by a truncated normal distribution function of its friction angle to produce a geostatistical equivalent to the deterministic bearing capacity. A method was first demonstrated to derive an analytical distribution function of the bearing capacity for a single surface footing with a rigid base layer for which an exact bearing capacity function is available. For the twin foundation problem with no explicit deterministic solutions, a Monte Carlo simulation was adopted. The stochastic bearing capacity relative to its deterministic equivalent was determined for a set of layer thicknesses and footing distances in terms of the assumed geostatistical characteristics of the sand and resulting bearing capacity distributions. The Monte Carlo methodology is adaptable in design to model other bearing capacity problems with more complex and random soil distributions.

Published: February 2019

ABSTRAK Monasit (Ce, La, Nd, Th,)PO4 dengan kandungan torium (Th) antara 3-4% cukup signifikan untuk diproses menghasilkan Th. Pengolahan awal dilakukan dengan pelindian monasit menggunakan reagen basa karbonat (Na2CO3) untuk mengambil uraniumnya. Sisa tailing dilarutkan dengan asam sulfat untuk menghasilkan larutan Th(SO4)2 yang kemudian dimurnikan dari unsur-unsur pengotornya. Pengolahan dilakukan secara kontinyu menggunakan mixer settler dengan tahapan proses meliputi proses ekstraksi Th, stripping Th dan regenerasi pelarut organik. Ekstraksi Th menggunakan pelarut organik Primene JM-T (RNH2) yang merupakan campuran dari 0,15M Primene JM; 5% Tridecanol; dan 95% Kerosin. Sementara itu, proses stripping Th menggunakan larutan 2M HCl. Untuk efisiensi maka regenerasi pelarut organik menggunakan 1% H2SO4. Untuk mendapatkan recovery dan kemurnian yang tinggi dari Th, penghitungan jumlah stage mixer settler diperlukan dengan menggunakan metode McCabe Thiele. Dari hasil perhitungan diperoleh jumlah stage dalam proses ekstraksi Th adalah 3, proses stripping Th adalah 3 dan regenerasi pelarut organik adalah 2. Recovery total Th sebesar 84,90% diperoleh dengan kemurnian produk mencapai 99,02%. ABSTRACT Monazite (Ce, La, Nd, Th)PO4 with thorium (Th) content between 3-4 % is significant enough to be processed to produce Th. The initial treatments conducted by using carbonate base reagents (Na2CO3) for monazite leaching to fetch the uranium. The remaining tailings were dissolved with sulfuric acid to produce Th(SO4)2 solution which is then purified from its impurities. The processing is carried out continuously using a mixer settler with the process steps include Th extraction, Th stripping, and organic solvents regeneration. Thorium extraction uses a primene JM-T (RNH2) organic solvent which is a mixture of 0.15M Primene JM; 5% Tridecanol and 95% Kerosine. Meanwhile, the Th stripping process uses 2M HCl solution. For efficiency, regeneration of organic solvents uses 1% H2SO4. To obtain a high recovery and purity from Th, it is necessary to calculate the number of stage mixer settlers using the McCabe Thiele method. Based on the calculation, the number of stage for extraction process, Th stripping, and organic solvents regeneration are 3, 3, and 2 respectively. The total recovery of Th is obtained at 84.90 % where product purity reaches 99.02 %.

Changes in the Use of Technology for Language Instruction at the University of Chicago, 2000-2007
Authors: Yang Kyung-Hwa Kay
Published: February 2019

This report is based on my own experience, which i gained through assisting foreign language instruction and linguistics research at the University of Chicago. Over the past few years, technology has become increasingly integrated in language instruction and changed not only the content but also the teaching paradigm. Instructors approach technology quite differently from the past and students are more actively involved in their learning process. Although it is open to dispute whether my observations correlate to general changes in the field of instructional technology, this script, however, may provide a vivid description of a recent situation in this field and suggest a future direction of the working ground.

For over eight years my career has been dedicated to the uses of technology in higher education. I began my career as an intern in the Advanced Multimedia Production Studio at Northwestern University, Illinois in 1999, and since 2000 have served as a manager and multimedia specialist in the Center for the Study of Languages at the University of Chicago (U of C). Over my period at the U of C, my daily tasks have changed although the crucial role of my position has not. I did and still do define the basis of my job as providing instructors with technology assistance for more effective teaching. Meanwhile, a subtle change has occurred: recently instructors began doing certain tasks which earlier were done by me or other trained staff. One of the reasons for this change is that many instructors now seem to consider technology not only as a pedagogical medium but also a tool that they need to learn how to use and incorporate into class. This use of technology often runs parallel with the changing roles of their counterpart, the students.

This report is based on my own experience, which I gained through assisting foreign language instruction and linguistics research at the U of C. Therefore, it is open to dispute whether my observations correlate to general changes in the field of instructional technology over the past few years. This report, however, may provide a vivid description of a recent situation in this field and suggest a future direction of the working ground.

Politeness Strategies in Wiki-mediated Communication of EFL Collaborative Writing Tasks
Authors: Li Mimi
Published: February 2019

Informed by the theory of social constructivism and computer-mediatedcommunication (CMC), wiki-mediated collaborative writing has beenincreasingly implemented in second or foreign language classes.However, to date, no research has addressed students’ interaction andnegotiation of their social relationship during wiki-mediatedcollaboration. Drawing on politeness theory, particularly Brown andLevinson (1987)’s taxonomy of politeness strategies, this studyanalyzed the wiki-mediated discourse of one collaborative writinggroup in a Chinese EFL context. This particular writing groupconsisted of three EFL college students at a southwestern university inChina. This article examined specifically how this small group activelyengaged in social interaction by adopting politeness strategies duringasynchronous communication in a wiki “Discussion” module. Resultsrevealed that this small group used three types of politeness strategies,i.e. positive, negative, and bald on record skillfully, to establishfriendship, solidarity and respect while completing their collaborativewriting tasks smoothly and efficiently. This study validates the value oflinguistic politeness strategies in the analyses of social interactionoccurring in computer-mediated discourse and also suggests somepedagogical implications.
Exploring the Benefits of ACMC for Speaking Development
Authors: James Nicolás Pino
Published: February 2019

Currently, language educators experience difficulties in facilitatingoral practice effectively in the foreign language classroom. Regularly,they face introverted and passive learners who fail to embracespeaking opportunities (Poza, 2011), or simply do not find the time topromote speaking practice in the classroom (Meddings & Thornbury,2009). In this light, many asynchronous computer mediatedcommunication (ACMC) technologies have emerged to confront thissituation. However, central research studies do not seem toacknowledge ACMC as viable in accommodating oral development but,rather, frequently attribute this merit to synchronous CMC (Levy &Stockwell, 2006; Kervin & Derewianka, 2011). By employing a mixedmethodsapproach, this small-scale case study examines, firstly, theextent to which ACMC speaking practices are suitable for languagelearners’ speaking development. Secondly, and by extension, itinvestigates the salient characteristics of the ACMC toolmyBrainshark, that makes it appropriate for fostering linguisticgrowth. The data is obtained from post-beginner Spanish languagelearners by means of an online questionnaire and an online structuredstimulated recall. The findings show, on the one hand, that ACMC oralpractices can be beneficial in developing speaking aspects in lowerproficiencylanguage learners and, on the other hand, thatmyBrainshark has characteristics that can potentially promotelinguistic development. Finally, this paper calls for experimentalresearch on the improvement of oral competency in post-beginner andhigher-proficiency learners.
Effects of Technology Modes on Ratings of Learner Recordings

Published: February 2019

While research has investigated the effect of visuals in tests of listeningcomprehension (e.g., Suvorov, 2009; Wagner, 2008, 2010), studentrecordedvideo for oral formative assessment is relatively unexplored.In this study, I examined 15 teachers’ ratings of speech recorded by 39ESL learners to see if teachers assess speech differently depending onwhether it is presented with visuals. The learners recorded 4 speechsamples: 2 with webcams, 2 with microphones only. A third speechcondition was created by removing the video track from the webcamrecordings, resulting in 3 conditions and 6 samples for each individual.The teachers rated all 6 samples. I used repeated-measures ANOVAs todetermine whether the teachers assigned significantly different scoresbased on the speech conditions. The results showed that the teachersrated the audio stripped from the video significantly higher than thevideo/audio recordings (p = .004, d = .38). This suggests that teachersmay be biased in favor of audio-only recordings and that teachersshould not give students an option of making either an audio or videorecording for a given formative assessment. Further analyses examinedhow the students’ and teachers’ preferences for audio-only or videorecordings were related to the ratings.

Realities of mobile learning technologies in foreign language classes
Authors: Huhn Christina , Dassier Jean-Louis , Liu Shijuan
Published: February 2019

While it is common to assume that our current undergraduates are digital native who are naturally proficient and expect the use of technology, the research base that supports those assumptions is limited. This is especially true of students in foreign language classes. Much of the national research that has been conducted has not focused on specific subsets of students. It is important to address this paucity of research, as instructors, textbook publishers, and other stakeholders must make informed decisions regarding the design and development of curriculum and instructional materials. This article reports a study conducted in exploration of the ownership and use of mobile devices by students in foreign language courses. The study used survey methodology and focus group protocols to investigate what technological devices students have and use for personal and academic activities. Salient findings include the reaffirmation of the need to maintain appropriate pedagogy in light of the latest and greatest technological developments, distinctions between the use of technology for content consumption versus content production, and a distinct preference for a separation between personal and academic activities among digital natives.
Collaboration Two-Way
Authors: Arnold Nike , Ducate Lara , Kost Claudia
Published: February 2019

Collaborative writing has been found to lead to more productive writing processes and enhanced final products in terms of a richer vocabulary, more accurate grammar, and better organization. The present study expands on this research strand by exploring if different group writing processes affect the quality of wiki texts composed by groups of intermediate German L2 learners. Defining true collaborative writing as involving both a balanced workload and a joint responsibility for the product from all group members, it measured collaboration in two ways. Results indicate that most of the 19 groups in this study had a somewhat unbalanced workload with wide variability in editing group members’ contributions. Although the wiki texts differed greatly with regard to quantitative measures of length, accuracy and cohesion, no correlation was found in terms of workload or co-ownership. While holistic ratings of the texts concerning accuracy and cohesion seemed at times incongruent with the analytic measures, the raters’ comments provided a perspective that captured facets and nuances of a text that the analytic indicators did not.
Intervenciones Artísticas: Estado de Excepción en México
Authors: Estévez Pablo
Published: February 2019

The movement of Zapatista rebellion in Chiapas, Mexico began in 1994, succeeding in generating a change in Mexican society by valuing indigenous liberation practices. However, a state of emergency is instituted in Zapatista territories according to laws that grant amnesty and regulate the legal vacuum. Certain Mexican artists such as Erick Beltrán, Gabriel Kuri, Abraham Cruzvillegas and Pablo Kubli, contribute critical reflections with works sustained in the context of pure violence of the State. The theoretical framework is constrained by the theories of Carl Schmitt, Walter Benjamin, Giorgio Agamben and Achille Mbembe, who contribute to the understanding of the state of exception that the State implements by modifying sovereignty and Human Rights. The method used in the article corresponds to the reception of literary texts. The artistic pieces that are integrated by Pablo Kubli represent the interdisciplinary contribution of the social sciences and the practice of art, with images, schemes and interventions that are argumentative reflections of the environment of globalized violence, and of social resistance to the paradigm of modification of autonomy in intervened regions. In addition, a comparative approach with states of emergency of globalized countries is proposed according to the events of September 11, 2001 in New York and March 11, 2004 in Madrid, among others. Starting from the Mexican experience and from global countries, the term of sovereignty is modified by the violence of the State over territories cut off by the permanence of the state of exception and restrictions on constitutional guarantees.

This paper is the transcript of the conference read on May 9, 2017 during the workshop The Power of Colors - The Spatial Experience with the Help of Art, at the Peter Behrens School of Arts, University of Applied Sciences, Hochschule Düsseldorf. It shows the ideas that art is capable of transmitting to architecture to design space through color planning. The reading describes in detail the creative process of the artist and professor at the University of Barcelona, Jaume Fortuny Agramunt, during the rehabilitation of architectural spaces through spatial experience with the help of art. Dr. Fortuny explains seven of his projects carried out in three Spanish cities (Badalona, Sant Quirze Del Vallès and Barcelona) within his line of research that he calls Analysis of the Relational Process Form-Space. These projects show how positive can be the transfer of knowledge to architecture from the area of Fine Arts to architecture from the field of Fine Arts, both from sculpture and painting, and the strong use of art for the everyday life of the society where it is generated.

Published: February 2019

El liderazgo pedagógico en Educación Secundaria supone el conocimiento de herramientas que minimicen los efectos nocivos en la salud y bienestar de los docentes, consecuentes a demandas físicas, mentales, emocionales y relacionales propios de este ámbito profesional. En esta dirección, la resiliencia, fortaleza que el ser humano desarrolla ante la adversidad, permite resistir el suceso estresante, rehacerse del mismo e incluso salir fortalecido de la experiencia. El presente estudio empírico pretende establecer relaciones entre las percepciones de burnout  y de resiliencia en docentes. La muestra invitada está compuesta por el profesorado de Educación Secundaria de los 24 Institutos de la red pública de enseñanza de la provincia de Huesca (N=1.268), en el curso 2014. Mediante participación voluntaria, se conforma la muestra definitiva con n=167 docentes (13,17%). La recolección de datos se realiza a través de dos cuestionarios: a) adaptación al castellano del Maslach Burnout Inventory-General Survey  (MBI-GS), de Salanova, Schaufeli, Llorens, Peiró y Grau (2000) y b) Cuestionario de Evaluación de Resiliencia de Serrano Martínez- Universidad de Zaragoza (2010). Los resultados confirman que las características personales y la resiliencia de la persona actúan como variables moduladoras frente al burnout , señalando una vía de mejora para el ejercicio de un liderazgo transformativo.

An attempt to identify artifacts using only analytical research methods is described. The regions of origin and production period of the lead anchor stock are determined, by investigating both the material of the stock and various inclusions into the stock’s material. Based on results of a complex of physical investigations, the stock is found to be made of high purity lead (99.95%) from the Lavrion mine (Greece). Its production relates to the period of AD 1st century – the beginning of AD 2nd century. It is assumed that the presence of a large amount of inclusions indicates the need for significant material savings for the production of the stock during the period of the depletion of lead deposits. The nail, founded inside the stock body, believed to be put into the casting mold, as a guard.
VICTIM-BLAMING AND THE CRISIS OF REPRESENTATION IN THE VIOLENCE PREVENTION FIELD
Authors: Fast Elizabeth , Richardson/Kinewesquao Cathy
Published: February 2019

In this article, the authors apply response-based practice to highlight the ways in which victims are blamed in cases of violence. They problematize and explore the misrepresentation of violence across academic disciplines and institutional systems, including the social sciences, the helping professions, and the justice system. Fast and Richardson discuss the linguistic operations that serve to conceal violence and also to obscure the resistance of the victim, which tends to reflect the level and brutality of the violent acts. In order to demonstrate the processes of shifting blame and responsibility from the perpetrator to the victim, the authors also discuss particular Indigenous examples relating to the issue of attacks on and kidnappings of Indigenous women, and to the connections between violence, resource exploitation, and land dispossession.
RESPONSES TO ADVERSITY FACED BY FARMING MEN: A GENDER-TRANSFORMATIVE ANALYSIS
Authors: Roy Philippe , Duplessis-Brochu Émilie , Tremblay Gilles
Published: February 2019

The values that characterize the traditional and stereotypical image of rural masculinity put pressure on farming men to engage with risky behaviours, both physical and mental, and reduce their willingness to seek help. This paper investigates individual and social responses to adversity, under the lenses of response-based practice and gender-transformative health promotion. Our method is based on qualitative semi-structured interviews with 32 farming men and 2 focus group interviews with 14 experts on men’s health, farming, and rural social work. Results suggest gender is negotiated through individual and social responses to adversity, with fluid transitions between conformity and resistance with regard to traditional masculinity. Individual responses to adversity can include negative or positive coping strategies. Social responses can be supportive, or they can be marginalizing, such as the devaluation of farming. For farmers facing adversity, there is a disparity in social support, with communal solidarity being evident in a material crisis, but not in a personal one. Some community-based responses are highlighted for their ability to support farming men in coping with adversity.
Periplasmic expression of a restriction endonuclease in Escherichia coli and its effect on the antiviral activity of the host

One possible mechanism preventing phage infection of the bacterial cells is related to the presence of an effective restriction-modification system (R-M) which allows restriction of the invading DNA. However, there are some limitations to the absolute restriction of foreign DNA. Since there is a serious conflict between increase in the restriction-modification genes expression level and cell viability, we examined the antiviral effect of EcoRI restriction endonuclease after its translocation to the periplasmic space of the cell. We assumed that such reconstructed R-M system could be able to degrade foreign DNA at the stage of its passage through the cell envelope of Gram-negative bacteria, before its penetration into the bacterial cytoplasm. The Tat secretion pathway of Escherichia coli was used to export R.EcoRI fused to the TorA leader peptide across the cytoplasmic membrane. However, although we observed a huge accumulation of the TorAss-R.EcoRI pre-protein in the cytoplasm the Tat system did not provide an efficient transport across the cytoplasmic membrane. Moreover, our data strongly suggest that endonuclease cannot function under the conditions prevailing in periplasmic space, therefore, the transported endonuclease could not contribute to an increase in restriction properties of the host.
Success in Closing the Socio-Economic Gap, But Still a Long Way to Go: Urban Aboriginal Disadvantage, Trauma, and Racism in the Australian City of Newcastle
Authors: Howard-Wagner Deirdre
Published: February 2019

The research presented in this article is based on a four-year place-based qualitative case study of Aboriginal success in addressing Aboriginal disadvantage in the Australian city of Newcastle. The article presents extracts from in-depth interviews with Aboriginal people working on a day-to-day basis with Aboriginal and/or Torres Strait Islander people experiencing disadvantage in this city. Interviewees define Indigenous disadvantage in a way that differs considerably from how it is defined in mainstream policy circles. They describe Indigenous disadvantage as being grounded in the histories of social exclusion from Australian society, rather than merely a contemporary phenomenon related socio-economic factors (i.e., lack of educational and employment opportunities). They indicated that it was (a) closely tied to Aboriginal experiences of displacement and trauma; (b) not just a material problem but a historical and social structural problem; and (c) unique to each community. For instance, urban Indigenous disadvantage is distinct from Indigenous disadvantage in remote areas. This supports the claims of Indigenous sociologist Maggie Walter (2009).
In doing so, the article more strongly aligns with a critique of a neo-liberal racial project, which defines Indigenous disadvantage within an individualistic framework of individual rights and in terms of socio-economic gaps, from the voices of Aboriginal representatives.
Factors Differentiating the Subjective Well-being of the Inhabitants of Wielkopolska According to the Criterion of Hierarchy of Their Life Values
Authors: Szubert Tomasz
Published: February 2019

The study examines the level of satisfaction with 21 different areas of life among 300 respondents from Wielkopolska voivodship at the age of 30 and over. What distinguishes this analysis from other such studies is the fact that when examining partial satisfaction, it was weighed by, specified subjectively by respondents, the importance of the areas for which this satisfaction was measured. In the course of the analysis, it turned out that the respondents were the most satisfied with their private life, life as parent and independence. The smallest satisfaction of the respondents derives from social activity, but it is above all the effect of the lack of meaning of this sphere of life in the hierarchy of respected life values. In addition, it has been noticed that within individual fields there are certain factors that differentiate probability of being more satisfied for some categories of people in comparison with others. Especially personality traits strongly affect the diversity of life satisfaction. Being a social person, trusting other people, being conscientious, peaceful and open to new experiences increase the probability of being a more satisfied person (especially with social areas) and having traits from the second pole of the personality scale reduces this probability.

The Intensity of University-Business Collaboration in the EU
Authors: Pleśniarska Aleksandra
Published: February 2019

It seems that collaboration between academia and the private sector represents one of important sources of knowledge transfer, which is a key element for creating the knowledge‑based economy. Moreover, knowledge transfer between universities and businesses is vital for innovation. The ability to create innovations is not only crucial for the development of enterprises but also for the development of a country’s economy. Business is interested in having access to the latest advances in science. On the other hand, activities of university are evolving from the basic functions of teaching and research to commercialisation of research results where the partnership with the private sector is one of the most important elements. Although there are numerous advantages of such collaboration, in reality, there are also constraints that hinder university‑business cooperation. The main purpose of the article is to present selected aspects of the intensity of university‑business collaboration in the Member States of the European Union (EU). In the first section of this article, advantages of and barriers to university‑business cooperation are discussed. In the second part, the discussion addresses the following factors: public‑private co‑publications per million population and the share of enterprises cooperating with academia. The ranking of the top universities that work with the most innovative firms is also presented in the article. The reflections will be based on the study of literature, European reports and documents. The main axis of investigation is a comparative analysis which draws its data from the Eurostat database. It is concluded that significant differences exist among the Member States – in countries such as Denmark, Sweden or Finland science‑business relations are at a good level. Furthermore, it seems that in the Member States of the EU large companies are more likely to engage in collaborations with higher education or public research institutions than small and medium‑sized enterprises (SMEs).
System identyfikacji wizualnej jako element tożsamości biblioteki akademickiej
Authors: Curyło Monika
Published: February 2019

The article presents the problem of creating and managing the brand of an academic library in the context of the university's identification system. Visual identity, understood as a mosaic of all visual messages, which facilitates recognition of a public institution, as well as brand awareness and development of long-term marketing strategies are the basic issues related to visual identification. The brand book (identity book), as well as printed and electronic materials, serve as a tool used to reinforce the institution's position on the market, and generate a coherent and logical system of symbols and connotations. The creation of a strong logo is one of the most important stages of building a corporate image, which has an ongoing influence on recipients and contributes to the success of a university and academic library brand.

The communications revolution implemented by social media has also influenced on public relations in libraries. Academic libraries, identified mainly with information and scientific activity, considered some new communications requirements of a user and the intercourses with environment via Facebook social network. How did the choice of communications tools 2.0 influence the relations with environment and the image of discussed libraries? In order to obtain an answer, the author of the article analysed tools and contents used by university libraries profiles on Facebook. The analysis was supplemented with the description of the interview’s results, conducted with administrators of university libraries’ profiles on Facebook.
Jóvenes conscriptos argentinos en tres espacios de movilización militar, década de los años setenta
Authors: Di Renzo Cristian Andrés , Mosiewicki Francisco
Published: February 2019

El artículo tiene como objetivo analizar la forma como jóvenes conscriptos argentinos fomentaron el ideal patriótico en tres casos de movilización militar: la destitución del presidente de facto Juan Carlos Onganía (1970), el llamado «Operativo Independencia» (1975) y el «Operativo Soberanía» (1978). En los tres casos seleccionados, se desarrollaron concepciones acerca del esfuerzo que la patria demandaba de los jóvenes que cumplían con su deber cívico dentro del servicio militar obligatorio. A su vez, en lo cotidiano, la experiencia bélica matizó tales lineamientos a la luz de las propias concepciones que los conscriptos tenían de lo que implicaba el deber. Partiendo de la metodología que aporta el campo de la historia de las emociones, se buscará entonces, comprender el cruce entre los esfuerzos por condicionar las experiencias emotivas de los jóvenes y la formación de contradiscursos y espacios de contra hegemonía. Asimismo, la puesta en valor de conceptos tales como «nacionalismo banal», permitirá debatir sobre las diversas formas que la identidad nacional constituyó, en tres coyunturas particulares que incentivaron la instauración de un fervor bélico nacional.
