Published: December 2018

O mogno africano (Khaya ivorensis) é uma espécie arbórea destinada à produção de madeira nobre. Apresenta elevado valor de mercado e boa adaptação edafoclimática à maior parte do território brasileiro. O objetivo do presente trabalho foi analisar a viabilidade econômica de plantio de mogno africano para produção de madeira nobre. Foi elaborado fluxo de caixa para um período de 20 anos. Os indicadores de viabilidade econômica calculados foram: valor presente líquido (VPL); taxa interna de retorno (TIR); payback; índice de rentabilidade e análise de sensibilidade, levando em consideração a variação de 60% para mais e para menos nos valores de investimento, receita e juros. O VPL calculado foi de R$ 11.296,72; a TIR 16%; o payback 19,92 anos; e o índice de rentabilidade foi de R$ 2,82 para cada R$ 1,00 investido. Na análise de sensibilidade, foi observado que apenas aumento acima de 15% nos juros, ou queda maior que 25% no valor da madeira tornaria o VPL negativo. Portanto, plantio de mogno africano é viável e apresenta baixa sensibilidade às variações do mercado.
Genetic characterization of some Turkish sheep breeds based on the sequencing of the Ovar-DRB1 gene in the major histocompatibility complex (MHC) gene region
Authors: Özdil Fulya , İlhan Fatma , Işık Raziye
Published: December 2018

Abstract. In this research, Ovar-DRB1 gene in the major histocompatibility complex (MHC) gene region was surveyed by
DNA sequencing in some of the native sheep breeds that are reared in Turkey.
A total of 80 samples were collected from eight different Turkish native sheep
breeds, and these samples were used for DNA sequencing. The exon 2 region of Ovar-DRB1 in the MHC gene region was polymerase chain reaction (PCR) amplified and sequenced. A
total of 25 new alleles were revealed in the Ovar-DRB1 gene in Turkish native sheep breeds
with 24 variable sites; only 13 sites were parsimony informative. The
average pairwise genetic distance was 0.029 % for the Ovar-DRB1 gene exon 2 region.
The sequence variations at eight different positions (7026, 7036, 7040, 7053,
7059, 7069, 7131 and 7214) are found in all of the studied samples. G →
C transversion at position 7081 is only seen in Akkaraman sheep breed,
whereas T → C transition at position 7097 is only seen in one sample
from the Akkaraman breed. Overall, two main groups were detected among the 25
alleles from Turkish native sheep breeds. All Daǧliç and Kivircik alleles
and one allele from Karayaka, Malya and Sakiz are grouped together while all
the other breeds are grouped in the other branch.

Abstract. Airborne and ground-based measurements of aerosol concentrations, chemical
composition, and gas-phase precursors were obtained in three valleys in
northern Utah (USA). The measurements were part of the Utah Winter Fine
Particulate Study (UWFPS) that took place in January–February 2017. Total
aerosol mass concentrations of PM1 were measured from a Twin Otter
aircraft, with an aerosol mass spectrometer (AMS). PM1 concentrations
ranged from less than 2 µg m−3 during clean periods to over
100 µg m−3 during the most polluted episodes, consistent with
PM2.5 total mass concentrations measured concurrently at ground
sites. Across the entire region, increases in total aerosol mass above
∼2 µg m−3 were associated with increases in the
ammonium nitrate mass fraction, clearly indicating that the highest aerosol
mass loadings in the region were predominantly attributable to an increase in
ammonium nitrate. The chemical composition was regionally homogenous for
total aerosol mass concentrations above 17.5 µg m−3, with 74±5 % (average ± standard deviation) ammonium nitrate, 18±3 %
organic material, 6±3 % ammonium sulfate, and 2±2 %
ammonium chloride. Vertical profiles of aerosol mass and volume in the region
showed variable concentrations with height in the polluted boundary layer.
Higher average mass concentrations were observed within the first few hundred
meters above ground level in all three valleys during pollution episodes. Gas-phase measurements of nitric acid (HNO3) and ammonia (NH3) during
the pollution episodes revealed that in the Cache and Utah valleys, partitioning
of inorganic semi-volatiles to the aerosol phase was usually limited by the
amount of gas-phase nitric acid, with NH3 being in excess. The inorganic
species were compared with the ISORROPIA thermodynamic model. Total inorganic
aerosol mass concentrations were calculated for various decreases in total
nitrate and total ammonium. For pollution episodes, our simulations of a
50 % decrease in total nitrate lead to a 46±3 % decrease in total
PM1 mass. A simulated 50 % decrease in total ammonium leads to a
36±17 % µg m−3 decrease in total PM1 mass, over the entire
area of the study. Despite some differences among locations, our
results showed a higher sensitivity to decreasing nitric acid concentrations
and the importance of ammonia at the lowest total nitrate conditions. In the
Salt Lake Valley, both HNO3 and NH3 concentrations controlled
aerosol formation.
Boundary-layer water vapor profiling using differential absorption radar

Published: December 2018

Abstract. Remote sensing of water vapor in the presence of clouds and precipitation
constitutes an important observational gap in the global observing system. We
present ground-based measurements using a new radar instrument operating near
the 183 GHz H2O line for profiling water vapor inside of
planetary-boundary-layer clouds, and develop an error model and inversion
algorithm for the profile retrieval. The measurement technique exploits the
strong frequency dependence of the radar beam attenuation, or differential
absorption, on the low-frequency flank of the water line in conjunction with
the radar's ranging capability to acquire range-resolved humidity
information. By comparing the measured differential absorption coefficient
with a millimeter-wave propagation model, we retrieve humidity profiles with
200 m resolution and typical statistical uncertainty of 0.6 g m−3 out
to around 2 km. This value for humidity uncertainty corresponds to
measurements in the high-SNR (signal-to-noise ratio) limit, and is specific to the frequency band
used. The measured spectral variation of the differential absorption
coefficient shows good agreement with the model, supporting both the
measurement method assumptions and the measurement error model. By performing
the retrieval analysis on statistically independent data sets corresponding
to the same observed scene, we demonstrate the reproducibility of the
measurement. An important trade-off inherent to the measurement method
between retrieved humidity precision and profile resolution is discussed.
The impact of bath gas composition on the calibration of
photoacoustic spectrometers with ozone at discrete visible
wavelengths spanning the Chappuis band

Published: December 2018

Abstract. Photoacoustic spectroscopy is a sensitive in situ technique for measuring the absorption coefficient for gas and aerosol samples. Photoacoustic spectrometers (PAS) require accurate calibration by comparing the measured photoacoustic response with a known level of absorption for a calibrant. Ozone is a common calibrant of PAS instruments, yet recent work by Bluvshtein et al. (2017) has cast uncertainty on the validity of ozone as a calibrant at a wavelength of 405 nm. Moreover, Fischer and Smith. (2018) demonstrate that a low O2 mass fraction in the bath gas can bias the measured PAS calibration coefficient to lower values for wavelengths in the range 532–780 nm. In this contribution, we present PAS sensitivity measurements at wavelengths of 405, 514 and 658 nm using ozone-based calibrations with variation in the relative concentrations of O2 and N2 bath gases. We find excellent agreement with the results of Fischer and Smith at the 658 nm wavelength. However, the PAS sensitivity decreases significantly as the bath gas composition tends to pure oxygen for wavelengths of 405 and 514 nm, which cannot be rationalised using arguments presented in previous studies. To address this, we develop a model to describe the variation in PAS sensitivity with both wavelength and bath gas composition that considers Chappuis band photodynamics and recognises that the photoexcitation of O3 leads rapidly to the photodissociation products O(3P) and O2(X, v > 0). We show that the rates of two processes are required to model correctly the PAS sensitivity. The first process involves the formation of vibrationally excited O3(X~ ) through the reaction of the nascent O(3P) with bath gas O2. The second process involves the quenching of vibrational energy from the nascent O2(X, v > 0) to translational modes of the bath gas. Both of these processes proceed at different rates in collisions with N2 or O2 bath gas species. Importantly, we show that the PAS sensitivity is optimised for our PAS instruments when the ozone-based calibration is performed in a bath gas with a similar composition to ambient air and conclude that our methods for measuring aerosol absorption using an ozone-calibrated PAS are accurate and without detectable bias. We emphasise that the dependence of PAS sensitivity on bath gas composition is wavelength dependent and we recommend strongly that researchers characterise the optimal bath gas composition for their particular instrument.
An integration and assessment of multiple covariates of nonstationary storm surge statistical behavior by Bayesian model averaging
Authors: Wong Tony E.
Published: December 2018

Abstract. Projections of coastal storm surge hazard are a basic requirement for
effective management of coastal risks. A common approach for estimating
hazards posed by extreme sea levels is to use a statistical model, which may
use a time series of a climate variable
as a covariate to modulate the statistical model and account for potentially
nonstationary storm surge behavior (e.g., North Atlantic Oscillation index).
Previous works using nonstationary statistical approaches to assess coastal
flood hazard have demonstrated the importance of accounting for many key
modeling uncertainties. However, many assessments have typically relied on a
single climate covariate, which may leave out important processes and lead to
potential biases in the projected flood hazards. Here, I employ a recently
developed approach to integrate stationary and nonstationary statistical
models, and characterize the effects of choice of covariate time series on
projected flood hazard. Furthermore, I expand upon this approach by
developing a nonstationary storm surge statistical model that makes use of
multiple covariate time series, namely, global mean temperature, sea level,
the North Atlantic Oscillation index and time. Using Norfolk, Virginia, as a
case study, I show that a storm surge model that accounts for additional
processes raises the projected 100-year storm surge return level by up to
23 cm relative to a stationary model or one that employs a single covariate
time series. I find that the total model posterior probability associated
with each candidate covariate, as well as a stationary model, is about
20 %. These results shed light on how including a wider range of physical
process information and considering nonstationary behavior can better enable
modeling efforts to inform coastal risk management.
Concentrations and radiative forcing of anthropogenic aerosols from 1750 to 2014 simulated with the Oslo CTM3 and CEDS emission inventory

Published: December 2018

Abstract. We document the ability of the new-generation Oslo
chemistry-transport model, Oslo CTM3, to accurately simulate present-day
aerosol distributions. The model is then used with the new Community Emission
Data System (CEDS) historical emission inventory to provide updated time
series of anthropogenic aerosol concentrations and consequent direct
radiative forcing (RFari) from 1750 to 2014. Overall, Oslo CTM3 performs well compared with measurements of surface
concentrations and remotely sensed aerosol optical depth. Concentrations are
underestimated in Asia, but the higher emissions in CEDS than previous
inventories result in improvements compared to observations. The treatment
of black carbon (BC) scavenging in Oslo CTM3 gives better agreement with
observed vertical BC profiles relative to the predecessor Oslo CTM2. However,
Arctic wintertime BC concentrations remain underestimated, and a range of
sensitivity tests indicate that better physical understanding of processes
associated with atmospheric BC processing is required to simultaneously
reproduce both the observed features. Uncertainties in model input data,
resolution, and scavenging affect the distribution of all aerosols species,
especially at high latitudes and altitudes. However, we find no evidence of
consistently better model performance across all observables and regions in
the sensitivity tests than in the baseline configuration. Using CEDS, we estimate a net RFari in 2014 relative to 1750 of
−0.17 W m−2, significantly weaker than the IPCC AR5 2011–1750
estimate. Differences are attributable to several factors, including stronger
absorption by organic aerosol, updated parameterization of BC absorption, and
reduced sulfate cooling. The trend towards a weaker RFari over recent years
is more pronounced than in the IPCC AR5, illustrating the importance of
capturing recent regional emission changes.

Abstract. The Bureau of Meteorology Atmospheric high-resolution Regional Reanalysis for Australia (BARRA) is the first atmospheric regional reanalysis over a large region covering Australia, New Zealand and southeast Asia. The production of the reanalysis with approximately 12 km lateral resolution – BARRA-R – is well underway with completion expected in 2019. This paper describes the numerical weather forecast model, the data assimilation methods, and the forcing and observational data used to produce BARRA-R, and analyses results from the 2007–2016 reanalysis. BARRA-R provides a realistic depiction of the meteorology at and near the surface over land as diagnosed by temperature, wind speed and precipitation. It shows closer agreement with point-scale observations and gridded analysis of observations, than leading global reanalyses. In particular, BARRA-R improves upon ERA-Interim global reanalysis in several areas at point-scale to 25 km resolution. BARRA-R shows reduced negative biases in (point-scale) 10 m wind speed during strong wind periods, reduced biases in (5 km gridded) daily temperature maximum and minimum, and higher frequency of very heavy precipitation days at 5 km and 25 km resolution. Few issues with BARRA-R are also identified; some of which are common in reanalyses, such as biases in 10 m wind, and others that are more specific to BARRA such as grid point storms. Some of these issues could be improved through dynamical downscaling of BARRA-R fields using convective-scale (
Climate change vs. socio-economic development: understanding the future South Asian water gap
Authors: Wijngaard René Reijer , Biemans Hester , Lutz Arthur Friedrich , Shrestha Arun Bhakta , Wester Philippus , Immerzeel Walter Willem
Published: December 2018

Abstract. The Indus, Ganges, and Brahmaputra (IGB) river basins provide about 900 million
people with water resources used for agricultural, domestic, and industrial
purposes. These river basins are marked as “climate change hotspots”, where
climate change is expected to affect monsoon dynamics and the amount of
meltwater from snow and ice, and thus the amount of water available.
Simultaneously, rapid and continuous population growth as well as strong
economic development will likely result in a rapid increase in water demand.
Since quantification of these future trends is missing, it is rather
uncertain how the future South Asian water gap will develop. To this end, we
assess the combined impacts of climate change and socio-economic development
on the future “blue” water gap in the IGB until the end of the 21st
century. We apply a coupled modelling approach consisting of the distributed
cryospheric–hydrological model SPHY, which simulates current and future
upstream water supply, and the hydrology and crop production model LPJmL,
which simulates current and future downstream water supply and demand. We
force the coupled models with an ensemble of eight representative downscaled
general circulation models (GCMs) that are selected from the RCP4.5 and
RCP8.5 scenarios, and a set of land use and socio-economic scenarios that are
consistent with the shared socio-economic pathway (SSP) marker scenarios 1
and 3. The simulation outputs are used to analyse changes in the water
availability, supply, demand, and gap. The outcomes show an increase in
surface water availability towards the end of the 21st century, which can
mainly be attributed to increases in monsoon precipitation. However, despite
the increase in surface water availability, the strong socio-economic
development and associated increase in water demand will likely lead to an
increase in the water gap during the 21st century. This indicates that
socio-economic development is the key driver in the evolution of the future
South Asian water gap. The transgression of future environmental flows will
likely be limited, with sustained environmental flow requirements during the
monsoon season and unmet environmental flow requirements during the low-flow
season in the Indus and Ganges river basins.

Abstract. The cultivation of bioenergy plants in fertile, arable lands
increasingly results in new land use conflicts with food production and cannot be
considered as sustainable. Marginal lands have been frequently considered as potential
alternatives for producing bioenergy from biomass. However, clear definitions and
assessment methods for selecting marginal lands and for calculating potentials are still
widely missing. The project “SEEMLA” aims at triggering the exploitation of currently underused
marginal lands for biomass production for energy purposes. Study sites have been selected
in different European countries: Germany, Greece, and Ukraine. The selected sites
represent a wide variety of different types of marginal lands. Based on a soil assessment
set given by the Muencheberg Soil Quality Rating (SQR) system potentially “marginal”
sites have been investigated. The SQR system allows for clearly distinguishing between
soils of higher and lower quality. Soils with SQR scores below 40 are regarded as
“marginal”. They can be classified into different groups with regard to the importance
of soil hazard indicators as evaluated by the SQR approach. The calculated SQR scores
correlate significantly with biomass yields of bioenergy plants. Further, the SQR method was adapted for use in a GIS study on marginal-land potentials in
Europe. Thus, 46 % of the investigated European area could be classified as
“marginal” with SQR scores below 40. From that area 22.6 % can be considered as
potentially suitable for producing renewable resources after eliminating protected sites
or other places not suitable for any kind of land use. Taking the ecological demands of
selected bioenergy plants into account it is possible to give first preliminary
recommendations for regional crop cultivation. It can be concluded that Europe offers a large potential for renewable resources from
marginal sites. However, the implementation into practice is often impeded by missing or
varying policies and regulations. A proper implementation needs clear regulations and
also incentives for farmers at the European level.
Exploring online interaction and online learner participation in an online science subject through the lens of the interaction equivalence theorem
Authors: Nieuwoudt Johanna
Published: December 2018

While researchers agree that student participation is key to learning, it seems that the issue of interaction in online learning is not yet resolved. The current study investigated students’ online interaction and online learner participation in an online enabling science subject and compared this with their final grades. The data were analysed through the lens of Anderson’s (2003) interaction equivalence theorem. The findings from the current study provide support for the interaction equivalence theorem. Student-teacher interaction and student-content interaction were evident, but not student-student interaction. Significant relationships were found between student success and online learner participation, but not online interaction. Generalisations are limited by a small sample size and online interaction and participation was measured in terms of quantity rather than quality. Still, following the interaction equivalence theorem, it appears that students can have a satisfying and meaningful learning experience despite not having student-student interaction.
First semester academic performance: The importance of early indicators of non-engagement
Authors: Van der Meer Jacques , Scott Stephen , Pratt Keryn
Published: December 2018

Success, progression and retention of students are goals of many university strategic directions and policies. For many decades it has been recognised that the greatest focus in any retention strategy should be on first-year students. University of Otago too has goals around student success. The Strategic Plan of the institution also identified that in the context of a fiscally constrained environment, all of our activities and processes need to be assessed for efficiency and effectiveness.  To this end, a pilot was undertaken in one area of the university to identify possible indicators of first-year students’ non-engagement in the first semester and their possible impact on the first semester academic performance. The findings suggest that there are indeed some indicators that predict Grade Point Average at the end of the first semester.

Published: December 2018

To examine the impact of cooperative learning strategy on the behaviour states of EFL learners, a 3-month study was conducted in 4 government secondary schools in EFL context (Saudi Arabia). This study aims to identify the effect of cooperative learning in comparison to traditional learning in learning English grammar on the behaviour states of EFL Learners. This study contributed to the knowledge about how EFL learners behave when they interact cooperatively together in cooperative learning groups in comparison to their colleagues who learn in traditional learning. In this study, the participants were 139 tenth grade male students, in 4 male government secondary schools in Al-Baha city, in Saudi Arabia context.An examination of the Kruskal‑Wallis tests shows that the EFL learners in the experimental conditions displayed more cooperative behavioural states and less non‑cooperative states, individual task‑oriented, and individual non‑task behaviours than their classmates in the control condition. In addition, outcome scores were, on average, higher in the experimental condition for cooperative behavioural outcomes. They were lower in the experimental condition for non‑cooperation behaviour, individual task oriented and individual non‑task oriented.

There are many factors influencing second language acquisition, such as learner external factors including social factors, the input of second language acquisition and the relationship between acquisition; internal factors including the transfer of language, cognition of second language and language universals, etc, which influence the psychological factors of learner's second language; individual differences include some factors in physiological emotion, cognition, and learning strategies. This article is to explore the role of learners in second language acquisition from the perspective of individual differences (age, aptitude, learning motivation).
Generic and action-dependent abilities in Spanish ‘Be capable’
Authors: Castroviejo Elena , Oltra-Massuet Isabel
Published: December 2018

This paper is concerned with the semantics of Spanish ser capaz ‘be capable’ (henceforth SC). Specifically, it aims to account for the distribution SC displays and the range of meanings it expresses in the realm of abilities, viewed as kinds of dispositions. We put forth the following generalization: Whenever imperfective aspect interacts with SC, two possible readings arise, one that is purely abilitative and another one that expresses an accidental or unpredictable state of affairs. Our claim is that both interpretations derive from a circumstantial modal base that includes the subject’s inner circumstances, albeit with a different ordering source that is brought about via the interaction of imperfective aspect and the syntax-semantics of the modal. Thus, we propose that the purely abilitative SC contains an ordering source that ranks as better worlds those in which the subject appeals to her strength of the body, intellect or character; the accidental reading is the result of covert movement of the adjective capaz ‘capable’ over the imperfective-bearing copula ser ‘be’, which triggers a change of ordering source in the modal.

Nurse leaders’ perceptions of the impact of their participation in a reflective practice program
Authors: Lavoie-Tremblay Mélanie , Cyr Guylaine , Primeau Gilbert , Aube Thalia
Published: December 2018

Since 2003, a university healthcare centre in Quebec (Canada) has offered its nursing leaders access to a long-term professional development program focusing on skills in Reflective Practice (RP). This program is based on teaching nursing leaders to interpret and reframe difficult, emotionally-charged situations they encounter on a regular basis, so they can improve their interpersonal interactions with their colleagues, patients, and patients’ families. This article describes the results of a qualitative study conducted in 2018 with 18 nursing leaders who participated for at least three years in the RP program. Participants were asked to describe their understanding of the RP approach, key learnings from the program, and parts of the training they found most valuable. They were also asked to define or share the program’s impact on their professional practice and leadership skills. It was found that the participants view RP as a useful tool for understanding and improving their interactions with others, and that it had led to concrete improvements in their interpersonal and leadership skills. Several of the positive changes described by participants are rarely described in other studies about the use of RP as a professional development tool in a clinical nursing setting.  The results suggest that when nurse leaders have participated for several years in an RP program, they experience different benefits than front-line staff with less long-term participation.
The Role of Learners’ Attitudes Toward Parental Involvement in L2 English Learning
Authors: Kim Jung-Tae , Barrett Rusty
Published: December 2018

This paper seeks to examine Korean EFL learners’ perceptions of parental involvement and how their attitudes toward parental involvement are associated with the success of parental involvement. Two hundred fifty four EFL children in South Korea participated in a survey asking the degree of their parent’s involvement in seven involvement types and their attitudes towards parental involvement. The results showed that while all types of parental involvement were positively correlated with English proficiency for the group of children with positive attitudes towards parental involvement, no such correlations were found for the group of children with highly negative attitudes. In addition, for the group of children with moderately negative attitudes toward parental involvement, only less direct, autonomy-supportive parental involvement was found to be related to their achievement. These results suggest that learners’ attitudes toward parental involvement may be a factor that delimits the positive influence of parental involvement on EFL learners’ achievement.
Courtroom Questioning Adapted to Legal Procedures
Authors: Haijuan Hu
Published: December 2018

This paper, taking linguistic theory of adaptation as its theoretical foundation, examines how courtroom questioning on the part of the judge is adapted to various contextual factors in legal setting. To account for the judge’s adaptation to the legal procedures in courtroom questioning, three types of questions are found as specific choices at different stages of courtroom trial. By choosing key-word questions, confirmation questions and consultative questions in accordance with the different legal procedures, the judge can decide a case confidently, therefore the institutional goal of solemnity, impartiality and effectiveness are achieved satisfactorily. This paper provides a new understanding of courtroom questioning in Chinese context, which will be a contribution to the general research on forensic linguistics and a pragmatic approach to the rhetoric of questioning in general.

Análise espacial dos ventos no Centro de Lançamento de Alcântara, Maranhão
Authors: Couto Vinicius Milanez , Fisch Gilberto
Published: December 2018

The wind at the Alcântara Launch Center (ALC), which presents as main characteristics an oceanic behavior, influenced by the trade winds and the sea breeze, and modified by the ocean-continent interface and local topography. Therefore, it is necessary to study the characteristics of the site flow, highlighting the influence of the surface boundary layer and the validity of the surface flow homogeneity. In this study will be used the data of two anemometric towers installed in the ALC to evaluate spatial differences in the characteristics of the average wind and its daily cycle. For comparison, data from the ERA5 reanalysis, the fifth generation created by European Centre for Medium-Range Weather Forecasts (ECMWF). The results show that the anemometric towers present, on average, similar characteristics and that the data from the reanalysis can be used for studies of mesoscale atmospheric phenomena that occur on the surface.

Published: December 2018

The aim of this work was to evaluate the performance of the WRF model for estimate wind speed in the central region of Alagoas State (Brazil). The wind velocity (WRF outputs) were compared with anemometric data of the PVPN projetc (Previsão do Vento em Parques Eólicos no Nordeste Brasileiro “Wind forecast for wind farms in the Brazilian Northeast”), from January to December 2014. The results showed that the WRF model estimated very well the monthly and daily wind speed averages. Deviations are greater in the dry season. Throughout the year the mean difference (WRF-OBS) was only 0.23 m.s-1 (6.14 m.s-1 versus 5.91 m.s-1), showing that this model is a good tool for forecasting wind for wind farms.

CARTOGRAFIA COMO PROCEDIMENTO METODOLÓGICO NO GRUPO DE ESTUDOS CERÂMICOS DO NUPEART PRO...MOVE
Authors:   Universidade do Estado de Santa Catarina, Gabriel Aionara Preis
Published: December 2018

Este trabalho tem como objetivo apresentar algumas reflexões acerca da cartografia como método de pesquisa desenvolvido no Grupo de Estudos Cerâmicos do XXXX, que procura unir o ensino teórico e prático da cerâmica por meio de encontros investigativos. Extraída do conceito de Rizoma de Gilles Deleuze e Félix Guattari, a metodologia por cartografia é uma prática singular com ênfase no processo e que legitima a construção coletiva de pesquisar. Com base em alguns procedimentos e propostas desenvolvidas durante os encontros, serão expostas algumas reflexões sobre as ações produzidas pelo grupo, articulando ao Rizoma e ao princípio de cartografia.

Published: December 2018

A análise de dois exemplos de escultura cerâmica monumental concluídas em 1993 e 1998, na cidade de Almada, Portugal, respetivamente o Monumento ao Associativismo e à Vida, é demonstrativa dos modos de promoção e produção da cerâmica adaptada às exigências dos projetos de escultura monumental para o espaço público. Obras que foram a génese de um modelo que levou ao estabelecimento, ao longo dos últimos vinte anos, de fortes ligações entre escultores, universidade, autarquias e os polos mais importantes da indústria cerâmica portuguesa, num contexto de contínua e agonizante crise na industria cerâmica. A análise da história destas duas obras, é a história de um modelo de promoção de escultura humanista por órgãos municipais socialmente engajados, no qual, a cerâmica de grande escala teve o seu protagonismo na cidade na década de 90, numa época de pujante infraestruturação urbana, contrariando a crise social-urbana de décadas anteriores.

Published: December 2018

Raku has been one of the favourite firing techniques since it allows low-firing and offers a wide range of colour options on glaze. Ceramicists’ researches in an effort to create different and alluring surfaces on a ceramic body have led to the enrichment of this technique with some variations. As a result of this quest, ceramic artists began experimenting with decorative effects on a ceramic body without using glaze in 1980s. Raku firing technique without using glaze, called Naked Raku in foreign sources, has twobasictypes, one-step nakedrakuandtwo-step nakedraku. Inone step nakedrakutechnique a thick slip is appliedtobisquefiredceramicpiecesand it is firedwhile it is wetandthenreduced. In two step nake drakuthin/ thick slip is applied and covered withlow- fire glazeandreduced. The aim of this study is to examine the development process of naked raku and giving examples from artist’s own experiences. The study includes today’s raku production process, the characteristics of clay, slip and glaze used in this process, and the firing technique.

Authors: Ishikura Yukiko
Published: December 2018

The International Baccalaureate (IB) offers internationally recognized programs that prepare students to think and act critically and independently as internationally competent individuals. IB has recently undergone a rapid worldwide expansion as an increasing number of educational systems are recognizing the value of nurturing globally prepared citizens. Japan, in particular, has witnessed a recent increase in the spread of IB programs because of the government-initiated push to increase the number of IB schools to 200 by 2020. The IB Dual Language Program (English and Japanese) was created to support this initiative. This article sheds light on the trend of IB expansion worldwide through the lens of the Japanese experience and addresses challenges and opportunities that this expansion has brought to Japanese higher education.
Japan: World-Class Universities for Social Innovation
Authors: Yonezawa Akiyoshi
Published: December 2018

A new world-class university policy called the Designated National University scheme was introduced in Japan in 2017. Six national universities are now given a distinguished legal status, differentiating them from all other national universities, and are expected to be competitive with leading universities worldwide. However, the government expects the selected universities to be capable of generating their own income. In light of the uncertainty surrounding the highly complex mechanism linking knowledge activities at universities and industrial commercialization, this appears to be a risk-taking policy.
