The aim of this work is to use a residue from shale gas production, known as retorted shale (RS), as an alternative material for processes of sulfur adsorptive desulfurization in liquid fuels such as gasoline or diesel. Therefore, retorted shale samples were chemically modified. Two methods were applied: acid leaching and impregnation. The first method (RS-HCl) was an acid treatment with HCl solution (3M) in proportion of 1.5: 10. The second method (RS-Fe) was a wet impregnation of 20%wt. of Fe followed by calcination at 700°C for 2 h. The adsorbents were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The adsorption tests were performed using a solution of n-heptane and thiophene to simulate a fuel with an initial concentration of 500 ppm of sulfur. The results showed that both methods significantly altered the structure of the retorted shale, mainly the amount of Fe2O3. The adsorption test results indicated that the adsorbents prepared can remove up to 90% of the sulfur present.

The immobilization of catalyzers is an alternative to aid the process of photocatalysis. The clays are compounds of high porosity and abundant in nature, therefore, this work aimed at carrying out a prospective study of the use of palygorskite as catalytic support for TiO2on the degradation of the bentazone herbicide. The bibliographic search on the database (Scopus, Web of Science and SciELO) and patent base (EPO, USPTO and INPI). The results showed that the published articles address the synthesis with excellent results on the degradation of different pollutants. With regard to the patents, it could be observed that some palygorskite-based materials have already been patented. The results show that palygorskite is an excellent alternative for obtaining materials with photocatalystic activity.

Published: September 2018

This work deals with preparation and characterization of asymmetric ceramic membranes using the residue as a precursor of granite, for use in the treatment of effluents. For this, were prepared ceramic supports of alumina coated with a layer of residue of granite and sintered at temperatures of 800, 850 and 900° C for 1h for each temperature. The characterization of the membranes was accomplished through the technique of scanning electron microscopy (SEM), flow measurements with deionized water and analysis of rejection of indigo blue in a synthetic effluent. SEM images revealed that the membrane sintered at 900°C was completely covered with a uniform layer of residue. Flow analysis with deionized water showed that the calcined membrane at 800oC presented the largest flow. Rejection tests showed that the membranes were efficient in removing indigo blue from effluent.

Published: September 2018

Due to the large quantity of fly ash produced during the combustion of coal, it has become necessary to give greater applicability to this residue of low commercial value. The residue contains inorganic oxides which can act on the crystalline structure of zeolites, namely silicon and aluminum oxide. The coal ash was submitted to physical and chemical treatments with the aim of potentiating the silicon and aluminum extraction from the residue. The pure ash and the treated ashes were characterized by: X-ray fluorescence (XRF), scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transformation infrared spectroscopy (FTIR). By means of the carried out characterizations it was observed that the treatments were effective for the extraction of aluminosilicates from the matrix. The treatments did not affect the morphology, the crystalline phases and neither the chemical composition of the ashes. Seeing this, the coal ash and its treatments showed to be a precursor for the synthesis of zeolites.

Published: September 2018

The waste generated in granite processing has caused great social and environmental concern due to the release of its solid effluents into landfills and other places. The recycling and reuse of waste from different industrial processes as new raw materials has been the object of various researches. The use of hydrocyclone in the treatment of residues can represent a very efficient tool for separation and purification of the granite residue. This work aims to characterize and analyse the technological properties of the granite sawdust residues submitted to the hydrocyclone process in comparison with the same residue without going through the hydrocyclone process. The results indicate that the material resulting from this process presented different characteristics from the material without the process, mainly in terms of granulometric distribution and technological properties.

Authors: Gonsalves Tayara Correia , Silva Franks Martins , Vieira Ligia Silverio , Casini Julio Cesar Serafim , de Faria Rubens Nunes
Published: September 2018

In recent years, extensive investigations have focused on the study and improvement of supercapacitor electrode materials. The electric devices produced with these materials are used to store energy over time periods ranging from seconds to several days. The main factor that determines the energy storage period of a supercapacitor is its self-discharge rate, i.e., the gradual decrease in electric potential that occurs when the supercapacitor terminals are not connected to either a charging circuit or electric load. Self-discharge is attenuated at lower temperatures, resulting in an increased energy storage period. This paper addresses the temperature-dependence of self-discharge via a systematic study of supercapacitors with nominal capacitances of 1.0 and 10.0 F at DC potentials of 5.5 and 2.7 V, respectively. The specific capacitances, internal resistances, and self-discharge characteristics of commercial activated carbon electrode supercapacitors were investigated. Using cyclic voltammetry, the specific capacitances were determined to be 44.4 and 66.7 Fg−1 for distinct carbon electrode supercapacitors. The self-discharge characteristics were investigated at both room temperature and close to the freezing point. The internal resistances of the supercapacitors were calculated using the discharge curves at room temperature. The microstructures of the electrode materials were determined using scanning electron microscopy.

Published: September 2018

Graphene has attracted significant interest because of its excellent electrical properties. However, a practical method for producing graphene on a large scale is yet to be developed. Graphene oxide (GO) can be partially reduced to graphene-like sheets by removing the oxygen-containing groups and recovering the conjugated structure. GO can be produced using inexpensive graphite as the raw material via cost-effective chemical methods. High vacuum and temperature (10−7 mbar and 1100°C, respectively) conditions are well-known to enable the preparation of reduced powder at the laboratory scale. However, a large-scale high vacuum reduction system that can be routinely operated at 10−7 mbar requires considerable initial capital as well as substantial operational and maintenance costs. The current study aims at developing an inexpensive method for the large-scale reduction of graphene oxide. A stainless steel vessel was evacuated to backing-pump pressure (10−2 mbar) and used to process GO at a range of temperatures. The reduction of GO powder at low vacuum pressures was attempted and investigated by X-ray diffraction and Fourier transform infrared spectroscopy. The experimental results of processing GO powder at various temperatures (200–1000°C) at relatively low pressures are reported. The microstructures of the processed materials were investigated using scanning electron microscopy and chemical microanalyses via energy dispersive X-ray analysis.
Chemical and Physical Variations on Cotton Wires

Published: September 2018

Cotton is a hydrofilic textile fiber and, for this reason, it changes its properties according to the environment changes. Moisture and Temperature are the two most important factors that lead a cotton Spinning sector and influence its quality. Those two properties can change the entire Spinning process. Understanding this, moisture and temperature must be kept under control when used during the Spinning process, once the environment is hot and dry, the cotton yarns absorb moisture and lose the minimal consistency. According to this information, this paper was developed testing four types of cotton yarns, one kind of cotton from Brazil and the others from Egypt. The yarns were exposed to different temperatures and moisture in five different tests and in each test, six samples that were examined through physical and mechanical tests: resistance, strength, tenacity, yarn´s hairness, yarn´s evenness and yarn´s twisting. All the analysis were accomplished at Laboratório de Mecânica dos Fluídos and at COATS Corrente S.A., where, it was possible to use the equipments whose were fundamental to develop this paper, such as the STATIMAT ME that measures strength, tenacity, Zweigler G566, that measure hairiness in the yarn, a skein machine and a twisting machine. The analysis revealed alterations in the yarn´s characteristics in a direct way, for example, as moisture and temperature were increased, the yarn´s strength, tenacity and hairness were increased as well. Having the results of all analysis, it is possible to say that a relatively low temperature and a high humidity, cotton yarns have the best performance.

In this study, cationic membranes based on poly (vinyl alcohol) (PVA) were synthesized, crosslinked with citric acid (carboxylic group) and 4-sulpho-phthalic acid (sulphonic group) for application as proton-conducting membranes of H3O+. The membranes were prepared from the mixture of PVA with the crosslinking agents (CA), previously dissolved and separated with the mixture of these. The CAs proportions used were 10%, 30% and 50%, based on the weight of PVA, and they were crosslinked at the temperatures of 120oC and 140oC. The films were characterized by thermal stability using TGA, spectroscopy ellipsometry (relative refractive index and real part of dielectric constant), swelling degree (water absorption) and conductivity, using electrochemical impedance spectroscopy (EIS). A variation in the refractive index as a function of CA concentration was observed. This fact was corroborated with the results of dielectric constant, because the higher concentration of hydrophilic group added to the film, higher the values of dielectric constant. The membranes which showed lowest swelling degree values were crosslinked with 4-sulpho-phthalic acid (sulphonic group), for example, the PVA membrane crosslinked with 50% of 4-sulpho-phtalic acid, at 140oC, showed 6.4% of water absorption, while the membrane PVA crosslinked with the same content of CA, but of citric acid, and temperature, presented 15.8%. The conductivity of some membranes, under the assay condition evaluated, was the same order of magnitude as the commercial membranes, Nafion®. The synthesized membranes have been showing potential application as cationic polymer membranes for the transport of H3O+.

Published: September 2018

The main objective of this work is to study and characterize porous ZrO2-TiO2 films on alumina substrates that will be used for the production of porous ceramic sensors for the monitoring of air humidity in environments subject to the incidence of solar radiation. For the production of the films the dip coating technique was adopted. A viscosity study was performed to obtain stable suspensions of ZrO2-TiO2 in isopropyl alcohol with the para-aminobenzoic acid deflocculant (PABA), at concentrations of 10, 12.5 and 15% by weight of solids. X-ray diffraction (XRD) characterizations were performed for the identification of crystalline phases, morphological analyzes by scanning electron microscopy (SEM) and chemical analyzes by energy dispersive X-ray spectroscopy (EDS). The results allowed to determine the minimum value of viscosity and amount of deflocculant to stabilize the suspension. The sensor elements in the form of 1:1 (weight) ZrO2 - TiO2 porous films showed great potential to be used as sensors for the measurement of relative humidity the size and distribution of desirable pores in the porous film for application as moisture sensors was obtained with 12.5 and 15 % by weight ZrO2-TiO2
Using Appreciative Inquiry to Inform Program Evaluation in Graduate Medical Education
Authors: Rama Jennifer A. , Falco Carla , Balmer Dorene F.
Published: September 2018

Background 

Graduate medical education programs are expected to conduct an annual program evaluation. While general guidelines exist, innovative and feasible approaches to program evaluations may help efforts at program improvement. Appreciative Inquiry is an approach that focuses on successful moments, effective processes, and programs' strengths.

Objective 

We implemented a novel application of Appreciative Inquiry and its 4 phases (Inquire, Imagine, Innovate, and Implement) and demonstrate how it led to meaningful improvements in a pediatric pulmonology fellowship program.

Methods 

As part of the Inquire and Imagine phases, the authors developed an interview guide that aligned with Appreciative Inquiry concepts. Two faculty members conducted semistructured interviews with a convenience sample of 11 of 14 fellowship alumni. Interviews were audiotaped, transcribed, and reviewed. A summary of the findings was presented to the Program Evaluation Committee, which then directed the Innovate and Implement phases.

Results 

Appreciative Inquiry was acceptable to the alumni and feasible with the authors' self-directed learning approach and minimal administrative and financial support. In the Inquire phase, alumni identified program strengths and successes. In the Imagine phase, alumni identified program changes that could aid transition to independent practice for future fellows (an identified program goal). Based on the results of the Appreciative Inquiry, program leadership and the Program Evaluation Committee selected improvements for implementation.

Conclusions 

For small programs, Appreciative Inquiry is an innovative and feasible approach to program evaluation that facilitates actionable program improvement recommendations.
Unconventional monetary policies, with a focus on quantitative easing
Authors: Lavoie Marc , Fiebiger Brett
Published: September 2018

This article distinguishes between credit easing policies and quantitative easing (QE) policies. The authors argue that there are two broad transmission mechanisms associated with quantitative easing: the Friedmanian mechanism, which is based on the theory of the money multiplier and the fractional-reserve banking system; and the Keynesian mechanism, advocated by Keynes in 1930, which relies on its impact on interest rates. The article also deals with the likely consequences of various incarnations of QE policies: QE done with banks, QE done with non-banks, QE for the people, Corbyn's people's QE and green QE. This is done by looking at the impact of these policies on the balance sheets of banks, private agents, the central bank and the government, and on their consequences for the fiscal balance of the government when taking into account the profits that are distributed by the central bank to the government. It is concluded that accounting tricks cannot modify reality.
Forms of globalisation: from ‘capitalism unleashed’ to a global green new deal
Authors: Michie Jonathan
Published: September 2018

What is termed ‘globalisation’ has taken many forms over the centuries. The last time we had a ‘free market’ form of globalisation, such as is largely in force across the world today, was in the run up to the First World War; goods, people and capital crossed borders, as the leading industrial economies sought economic advantage in a process that ultimately spilled over into armed conflict. This led to a retrenchment between the world wars, with most governments focusing more on their own domestic economies and policy agendas. Following the Second World War, an era of ‘managed globalisation’ has been dubbed the ‘Golden Age of Capitalism’. This was followed by the era, launched by the Thatcher and Reagan administrations, of deregulation, privatisation, financialisation and demutualisation – of ‘capitalism unleashed’. That led to the 2007–2008 global financial crisis and the 2009 Great Recession. We now need to shape a new historical era, focused on environmental and social sustainability. This will require new economic thinking, and a policy agenda around a global green new deal.
Diversity and the dynamics of capitalism
Authors: Amable Bruno
Published: September 2018

The diversity of models of capitalism is evolving under the dynamics of capitalism itself, which imposes common trajectories to some institutional forms, such as the financial system or the employment relationship. This article argues that the analysis of the dynamic diversity and commonalities of capitalism can be made by focusing on four elements: the institutions defining the socio-economic model, the dominant social bloc that supports these institutional arrangements, the political actors and the strategy they have for uniting the dominant social bloc, and the public policies, in particular economic policies, implemented by the government.
Distributions of total and size-fractionated particulate 210Po and 210Pb activities along the North Atlantic GEOTRACES GA01 transect: GEOVIDE cruise
Authors: Tang Yi , Castrillejo Maxi , Roca-Martí Montserrat , Masqué Pere , Lemaitre Nolwenn , Stewart Gillian
Published: September 2018

Abstract. Vertical distributions of total and particulate polonium-210
(210Po) and lead-210 (210Pb) activities in the water
column were measured at 11 stations in the North Atlantic during the
GEOTRACES GA01 transect: GEOVIDE cruise in May–June 2014.
Total 210Po activity was on average 24 % lower than
210Pb activity in the upper 100 m, and it was closer to unity in
the mesopelagic (100–1000 m). The partitioning coefficients
(Kd) along the transect suggest the preferential association of
210Po relative to 210Pb onto particles. The prominent
role of small particles in sorption was confirmed by the observation that
over 80 % of the particulate radionuclide activity was on small
particles. To account for the observed surface water
210Po ∕ 210Pb disequilibria, particulate radionuclide
activities and export of both small (1–53 µm) and large (>53 µm) particles must be considered. A comparison between the
GEOVIDE total particulate 210Po ∕ 210Pb activity
ratios (ARs) and the ratios in previous studies revealed a distinct
geographic distribution, with lower particulate ARs in the high-latitude
North Atlantic (including this study) and Arctic in relation to all other
samples. For the samples where apparent oxygen utilization (AOU) was
calculated at the same depth and time as the
210Po ∕ 210Pb AR (40 stations including this study),
there was a two-phase correlation between the total particulate AR and AOU,
likely reflecting the nature of the particles and demonstrating the forces of
remineralization and radionuclide decay from particles as they age.
Implementation and Performance of Adaptive Mesh Refinement in the Ice Sheet System Model (ISSM v4.14)
Authors: Dias dos Santos Thiago , Morlighem Mathieu , Seroussi Hélène , Remy Bernard Devloo Philippe , Cardia Simões Jefferson
Published: September 2018

Abstract. Accurate projections of the evolution of ice sheets in a changing climate require a fine mesh/grid resolution to correctly capture fundamental physical processes, such as the evolution of the grounding line, the region where grounded ice starts to float. The evolution of the grounding line indeed plays a major role in ice sheet dynamics, as it is a fundamental control on marine ice sheet stability. Numerical modeling of grounding line requires significant computational resources since the accuracy of its position depends on grid or mesh resolution. A technique that improves accuracy with reduced computational cost is the adaptive mesh refinement approach, AMR. We present here the implementation of the AMR technique in the finite element Ice Sheet System Model (ISSM) to simulate grounding line dynamics under two different benchmarks, MISMIP3d and MISMIP+. We test different refinement criteria: (a) distance around grounding line, (b) a posteriori error estimator, the Zienkiewicz-Zhu (ZZ) error estimator, and (c) different combinations of (a) and (b). We find that for MISMIP3d setup, refining 5 km around the grounding line, both on grounded and floating ice, is sufficient to produce AMR results similar to the ones obtained with uniformly refined meshes. However, for the MISMIP+ setup, we note that there is a minimum distance of 30 km around the grounding line required to produce accurate results. We find this AMR mesh-dependency is linked to the complex bedrock topography of MISMIP+. In both benchmarks, the ZZ error estimator presents high values around the grounding line. Particularly for MISMIP+ setup, the estimator also presents high values in the grounded part of the ice sheet, following the complex shape of the bedrock geometry. This estimator helps guide the refinement procedure such that AMR performance is improved. Our results show that computational time with AMR depends on the required accuracy, but in all cases, it is significantly shorter than for uniformly refined meshes. We conclude that AMR without an associated error estimator should be avoided, especially for real glaciers that have a complex bed geometry.
The Kerala flood of 2018: combined impact of extreme rainfall and
reservoir storage

Published: September 2018

Abstract. Extreme precipitation events and flooding that cause losses to human lives and infrastructure have increased under the warming climate. In August 2018, the state of Kerala (India) witnessed large-scale flooding, which affected millions of people and caused 400 or more deaths. Here, we examine the return period of extreme rainfall and the potential role of reservoirs in the recent flooding in Kerala. We show that Kerala experienced 53 % above normal rainfall during the monsoon season (till August 21st) of 2018. Moreover, 1, 2, and 3-day extreme rainfall in Kerala during August 2018 had return periods of 75, 200, and 100 years. Six out of seven major reservoirs were at more than 90 % of their full capacity on August 8, 2018, before extreme rainfall in Kerala. Extreme rainfall at 1–15 days durations in August 2018 in the catchments upstream of the three major reservoirs (Idukki, Kakki, and Periyar) had the return period of more than 500 years. Extreme rainfall and almost full reservoirs resulted in a significant release of water in a short-span of time. Therefore, above normal seasonal rainfall (before August 8, 2018), high reservoir storage, and unprecedented extreme rainfall in the catchments where reservoirs are located worsened the flooding in Kerala. Reservoir operations need be improved using a skillful forecast of extreme rainfall at the longer lead time (4–7 days).
Insurance engagement in flood risk reduction – examples from household and business insurance in developed countries
Authors: Seifert-Dähnn Isabel
Published: September 2018

Abstract. Insurance can be an important mechanism to stimulate flood risk reduction and
thus decrease losses. However, there is a gap between the theoretical
potential described by academic scholars and the actual engagement of
insurers. In the analysis, I have collected examples of insurers' engagement
in flood risk reduction, focusing on household and business insurance in
developed countries. Insurers engaged either directly, e.g., through
co-financing risk reduction, or more indirectly by giving incentives to
policyholders or governmental actors to adopt risk reduction measures. I
analyzed their engagement with the framing conditions of the market they were
acting in, such as market penetration or private or public insurance schemes.
I found risk reduction measures like awareness-raising campaigns targeting
citizens to be quite common across several countries. There was less
insurance engagement in risk reduction measures such as warning or land-use
planning, which are perceived to be mainly governmental tasks. The use of
risk-based pricing as an incentive for the adoption of risk reduction
measures as suggested by academia is difficult in practice, due to barriers
such as information gaps on the effectiveness of property-level protection
measures and requirements concerning the affordability of insurance. New
approaches to overcome these shortfalls include organized data collection on
property-level protection measures or the insurance of high-risks for
affordable premiums in public–private partnership constellations with the
government.
Investigation of a wind-packing event in Queen Maud Land, Antarctica
Authors: Sommer Christian Gabriel , Wever Nander , Fierz Charles , Lehning Michael
Published: September 2018

Abstract. Surface snow in polar and mountainous regions is often mobile
and this mobility influences surface mass balance and isotopic composition
before final deposition, which is poorly understood thus far. In
December 2016 and January 2017, during a field campaign in Queen Maud Land,
Antarctica, a snowfall and subsequent drifting snow events were recorded by
meteorological and drifting snow stations. Associated small-scale topography
changes and snow hardness changes were measured by terrestrial laser scanning
and with a SnowMicroPen. The polar field measurements show that drifting snow
is necessary for wind packing and thereby confirm previous findings from wind
tunnel experiments. However, the snow hardness in Antarctica was
significantly higher than what was achieved in the wind tunnel. This is most
likely due to higher wind speeds and more intense saltation in the natural
environment. As in the wind tunnel, no influence of time at a scale of days
was observed on the hardness. This suggests that time and sintering are not
the dominating processes in wind packing but that the impact compaction at
the moment of deposition may be more important. Furthermore, it is
quantitatively demonstrated how the reorganization of fresh snow into barchan
dunes during subsequent drifting snow events is accompanied by significant
increases in surface hardness at all locations on the dune. However, with the
available data, the hardness variability on the dune could not be explained
satisfactorily. In particular and unlike in the wind tunnel, there was no
correlation between the hardness and the wind exposure parameter Sx. This is
most likely because the measurements of hardness and the wind exposure
situation were not simultaneous. This shows that highly temporally resolved
snow depth data are necessary to investigate wind packing in more detail.
These results form an important step in understanding how drifting snow links
precipitation to deposition via snow hardening.

What is the meaning of sharing: informing, being informed or information overload?
Authors: Haugsbakken Halvdan
Published: September 2018

In recent years, several Norwegian public organizations have introduced Enterprise Social Media Platforms. The rationale for their implementation pertains to a goal of improving internal communications and work processes in organizational life. Such objectives can be attained on the condition that employees adopt the platform and embrace the practice of sharing. Although sharing work on Enterprise Social Media Platforms can bring benefits, making sense of the practice of sharing constitutes a challenge. In this regard, the paper performs an analysis on a case whereby an Enterprise Social Media Platform was introduced in a Norwegian public organization. The analytical focus is on the challenges and experiences of making sense of the practice of sharing. The research results show that users faced challenges in making sense of sharing. The paper indicates that sharing is interpreted and performed as an informing practice, which results in an information overload problem and causes users to become disengaged. The study suggests a continued need for the application of theoretical lenses that emphasize interpretation and practice in the implementation of new digital technologies in organizations.

“First Connections with Stagecraft”: S. N. Behrman Finds His Vocation
Authors: Ljungquist Kent
Published: September 2018

This article discusses previously unpublished material from the S. N. Behrman Papers that marks S. N. Behrman’s first encounter with live theater. This material is thus a significant contribution to the biographical record on Behrman. A theater memoir submitted to but rejected by The New Yorker sheds light on Behrman’s early experiment in vaudeville, and records his early encounter with high comedy in the work of Somerset Maugham and his early fascination with actors, a primary focus of his theatrical career. The unpublished material discussed here was intended as part of his New Yorker series about growing up in a Jewish neighborhood in central Massachusetts, reminiscences seen as a resource for information about Behrman’s adolescence and early adulthood. Since Behrman’s book The Worcester Account (1954) offers only passing mention of the author’s eventual career in drama, the material covered here illuminates his choice of a vocation in the world of theater.
Environmental responsibility in hospital care: Findings from a qualitative study
Authors: Kallio Hanna , Pietilä Anna-Maija , Johnson Martin , Kangasniemi Mari
Published: September 2018

Objective: To identify the key elements of environmental responsibility in hospital care and the stakeholders involved.Background: Hospital care causes a significant global environmental burden, which threatens human health and wellbeing. Environmental responsibility has been identified as an essential part of patient care with regard to health promotion and wellbeing of humans, but it has often been regarded as a secondary issue in hospitals. In addition, the lack of organizational structures and administrative as well as managerial support inhibit the promotion of environmental responsibility in hospitals.Methods: We used a qualitative study with semi-structured interviews and document analysis. Our data was drawn from the environmental managers of five Finnish university hospitals and documents on their environmental programs.Results: We found that the aim of environmental responsibility in hospital care was to avoid unnecessary emissions, and that it was guided by the authorities and by ethical values. It included targets for sustainable use of material, electricity, water and transport. Environmental responsibility required the involvement of several stakeholders, including administrators, environmental manager, immediate leaders, environmental support people, staff and patients. Implementation of environmental responsibility was promoted by collaboration, education, diverse initiatives to motivate staff, and continuously developing practices.Conclusions: Environmental responsibility extended throughout a hospital organization. Staff was in a key position to implement it, but they needed versatile organizational support, including education, clear procedures, defined roles, and a motivational culture and facilities.Implications for hospital management: This study yields new knowledge that will provide information for the development of organisational structures with respect to environmental responsibility in hospital care.

Racial disparity in the Dutch juvenile justice system

In the United States, the term disproportionate minority contact (DMC) is used to refer to the disproportionate number of minority youth who come into contact with the juvenile justice system. Statistics on DMC in the United States put the issue on the political agenda and measures have been taken to reduce the inequality. In the Netherlands, there are some studies on the representation of ethnic minority groups in suspect statistics, but data regarding all ethnic groups at various stages of the juvenile justice chain are lacking. Due to this lack of information, DMC is not mentioned in Dutch research literature and is not a political issue. Therefore, the purpose of this article was to explore whether DMC existed in the Netherlands and whether elements of the US policy could be applied to the Dutch situation. To investigate this, the likelihood (odds ratio (OR)) was calculated for young people with a migration background to be registered and held as a suspect, to participate in an alternative punishment program (Halt) and their likelihood of incarceration. It turned out that the OR for young people with a non-Western migration background to be registered as a suspect was more than three times as high, with an OR of 5 or higher for some ethnic groups. The chances of a Halt-settlement were much lower for young people with a non-Western background. The odds of ending up in a youth prison was over six times higher for youngsters with a non-Western background compared to their Dutch native peers. For young people of Caribbean and Moroccan origin the likelihood was more than ten times higher. These results showed that DMC is present at all examined stages in the Dutch juvenile justice chain. The large overrepresentation of young people with a migration background (especially of Moroccan and Caribbean origin) shows that further research is needed in order to develop programs to reduce DMC. To establish this, it is important to register the ethnic origin of the individuals at all stages of the juvenile justice chain.

Adolescents and young adults in the Dutch youth justice system: the state of affairs four years after the entry into force of the Dutch Act on Adolescent Criminal Law

On 1 April 2014, the Dutch Act on Adolescent Criminal Law entered into force. With this law, the age limit in article 77c of the Criminal Code, which allows for the application of juvenile criminal law to young adults, was stretched from 21 to 23 years. In this article stock is taken of the developments that have taken place in the four years after the introduction of this law. In practice, article 77c Criminal Code is increasingly being applied in case of young adult suspects, however still to a little extent. Among others, this has to do with confusion about the target group that qualifies for the adolescent criminal law. The access to and justification for the application of the law show a very diverse picture.

Published: September 2018

The aim of the study was to evaluate the fistula test in patients of chronic otitis media with cholesteatoma and co-occurrence of fixation nystagmus. The results show limited diagnostic usefulness of fistula test due to the absence of a typical fistula nystagmus and prevalence of fixation instability. However, vestibular-spinal reactions and vertigo were observed in the test, which points to the usefulness of these symptoms in diagnostic procedures.
THE REPRESENTATION OF EXPERIENCE IN UNDERGRADUATE BUSINESS STUDENTS’ TEXTS: A FUNCTIONAL ANALYSIS OF MULTIMODAL MEANING MAKING RESOURCES IN MARKETING TEXTS
Authors: Alyousef Hesham Suleiman
Published: September 2018

From the Systemic Functional Linguistics (SFL) standpoint, experiential meanings reflect our experience, perceptions, and consciousness. Research on experiential meaningmaking in tertiary contexts has traditionally focused on areas such as mathematics, journalism and media, science and computing, nursing, and history. This paper aims to investigate the experiential multimodal meanings in an undergraduate marketing course. The data comprised three written assignments and the tutor’s two model texts. The study employed a multidimensional approach by Alyousef (2013), which is framed by SFL (Halliday 2014) and O’Halloran’s (2005, 1998, 2008, 1999) multisemiotic framework for the analysis of semiotic codes in mathematics. The results showed that the experiential meanings in the students’ marketing plan texts were primarily construed through material processes and both explicit and implicit relational identifying processes. The findings indicated how mathematical symbolism is encoded in the multisemiotic texts, in the most economical manner, by using grammatical strategies of structural condensation. The results also noted the extent to which the different modes of meaning were integrated in the texts.
AUTHOR’S SELF-REPRESENTATION IN RESEARCH ARTICLES BY ANGLOPHONE AND SLOVAK LINGUISTS
Authors: Walková Milada
Published: September 2018

The tension between the need to present oneself in academic discourse unobtrusively on the one hand and promotionally on the other hand results in a range of options of hiding and revealing authorial presence in the text. The choice from among these options is, among other factors, determined by cultural background. This paper explores how Anglophone writers and Slovak authors writing in Slovak and in non-native English position themselves in linguistic research papers as individuals or as part of a society, and as participants or non-participants of the given communicative exchange. The study concludes that English academic culture is largely individualistic while Slovak academic culture is largely collectivist, a trait that Slovak authors also transmit into their writing in English for a mainly local audience.

Prior to the start of any Wind Power Park construction project, it is necessary to carefully assess available wind potential in the selected area. The cost of such investigative studies is considerable – even with a relatively small 70 m tall mast it reaches several tens of thousands of Euros. In order to reduce costs related to wind speed measurements it is suggested to use the existing cellular communication masts that are widely spread in Europe. The study presents a methodological approach and the results of wind speed and wind shear measurements performed with the use of lattice cellular communication masts at the height of up to 100 m. A CFD model of airflow around a cellular communication mast structure was created in order to explore the impact of mast structure on the quality of wind speed measurements. The paper presents the results of the CFD modelling in the form of contour maps depicting the severity of airflow disturbances around the mast. The study is based on experimental measurements conducted in 2018 in three coastal sites of Latvia. At each site wind speed and direction were measured at several heights along with air temperature, humidity and air pressure. The experimentally obtained data in combination with the analysis of modelled CFD results shows the possibility of using cellular communication masts for accurate measurements of wind speed. Overall, the study shows that the proposed approach to wind speed measurements can result in high quality data and reduced overall expenses.
La pédagogie féministe : sens et mise en action pédagogique

Published: September 2018

Les auteures abordent la pédagogie féministe du point de vue des membres du Réseau québécois en études féministes (RéQEF). Elles s’appuient sur une démarche inductive pour circonscrire et comprendre leurs conceptions de la pédagogie féministe, leurs pratiques pédagogiques féministes, examiner les facteurs qu’elles désignent comme des obstacles ou des catalyseurs par rapport à sa mise en action et connaître les stratégies qu’elles utilisent afin de contourner ces obstacles. Pour ce faire, les auteures ont revisité les différentes définitions de cette pédagogie dans la littérature féministe. Ainsi, 25 ans après la parution des premiers textes en français sur la pédagogie féministe, les données issues du sondage interne et d’une demi-journée de discussion avec des membres du RéQEF révèlent que peu de choses ont changé : les définitions, les stratégies et les obstacles d’une pédagogie féministe sont sensiblement les mêmes. Les auteures se penchent également sur les quatre débats qui ont émergé des discussions : 1) l’importance de révéler la position située de la personne enseignante peu importe le contexte; 2) la distinction entre bonnes pratiques pédagogiques et pratiques pédagogiques féministes; 3) la distinction entre une pédagogie anti-oppression et une pédagogie féministe; et 4) la place relative donnée aux savoirs expérientiels comparativement aux savoirs savants.
Les rapports sociaux de sexe dès la petite enfance : une analyse de genre du Programme éducatif des services de garde du Québec, Accueillir la petite enfance1
Authors: Trudel Josée
Published: September 2018

Le Programme des services de garde éducatifs du Québec, Accueillir la petite enfance, est un des principaux fondements soutenant la formation initiale et la pratique quotidienne du personnel éducateur. Or, aucune analyse de genre de ce document central à l’éducation des enfants de 0 à 5 ans n’aurait à ce jour été effectuée. En ressort une volonté discursive d’éducation à l’égalité, mais aussi plusieurs éléments contrevenant à ces aspirations. L’omission de la construction sociale des différences entre les sexes, l’absence de toute identité sexuelle autre que garçon et fille, la dissonance entre les fondements théoriques de lutte contre les stéréotypes sexuels et la perpétuation de nombre d’entre eux, de même qu’une rédaction non sexiste déficiente, représentent les principaux défis liés au genre auxquels devront répondre les rédactrices et les rédacteurs à l’occasion de la mise à jour de ce document de base dans le domaine de l’éducation à l’enfance.
Déconstruire le manuel d’histoire pour (re)construire des savoirs plus justes : récit de pratique en formation initiale et continue des enseignantes et des enseignants
Authors: Brunet Marie-Hélène , Demers Stéphanie
Published: September 2018

Les pédagogies féministes s’articulent autour de la reconnaissance et de la lutte contre les mécanismes d’oppression et de subordination dans la construction sociale du féminin qui perpétuent la disqualification des femmes et de leurs voix. L’École contribuerait à cette construction par ses contenus et les postures sous-jacentes à leur apprentissage, ce qui la ferait ainsi participer à une vaste œuvre de reproduction sociale consolidée notamment par l’autorité conférée à ses discours, dont ceux des manuels scolaires. Le récit de pratique présentée par les auteures décrit un atelier donné en formation initiale à l’enseignement, de même qu’à des enseignantes et à des enseignants en formation continue, et certains de ses effets. À l’aide du concept d’agentivité historique, les participantes et les participants ont exercé leur agentivité épsitémique en comparant les récits offerts par différents manuels d’histoire, en commentant les rôles attribués aux femmes dans les différentes trames narratives et en repérant les obstacles à la compréhension de l’agentivité des femmes dans l’histoire.
