Building Reflective Practices Through a Digital Literacy Portfolio in an Online Context
Authors: Arnold Jackie Marshall , Sableski Mary-Kate
Published: September 2019

Digital storytelling is a way to utilize evidence-based practices in an online context that incorporates foundational literacy content with digital tools. Two literacy professors sought to maximize candidate learning and engagement through authentic, purposeful practices. This chapter details the utilization of a digital literacy portfolio assignment as part of an online, collaborative context to facilitate candidates' articulation of beliefs and understandings about effective literacy instruction. As candidates engage across both the face-to-face and online contexts, they develop understandings about effective literacy instruction, the application of digital tools in the classroom instruction, and a lived sense of the content of the ILA Standards that will inform their future practice. While teacher education programs face political scrutiny and intense pressure to incorporate vast amounts of content, the assignment described in this chapter provides an opportunity to facilitate candidates' learning in an online environment.
Using Case Methods in Online Teacher Education to Develop Culturally Sustaining Educators
Authors: Warren Amber N. , Ward Natalia A.
Published: September 2019

This chapter describes how case methods, namely discussion and reflection on published case studies, were used in online courses to promote the development of linguistically responsive and culturally sustaining practices. Participants included pre- and inservice teachers enrolled in courses for add-on licensure preparing them to work with English learners (ELs) as literacy and language teachers in Pre-K through 12 settings. Content analysis showed that cases (1) served as a catalyst for recognizing educational inequality preventing ELs from succeeding academically, (2) led participants to reflect on their beliefs and practices and make personal connections, and (3) prompted participants to offer practical classroom-level and broader structural solutions to address inequities in education of ELs. Reflections on what worked and considerations for using case methods in online literacy and language teacher preparation are described.
Re-Envisioning Authentic Literature Integration for Online Teacher Education
Authors: Enriquez Grace , Shinas Valerie Harlow , Steckel Barbara
Published: September 2019

This chapter discusses how the important evidence-based practice of integrating authentic children's literature across literacy learning activities is a critical component of online teacher education. Rather than focus on a single course within an online literacy program, the authors consider the pedagogical practices threaded throughout an entire online program designed for literacy educators. The chapter demonstrates how, utilizing various digital tools, this practice is woven into the online program's theoretical foundations, methods, and capstone courses, ultimately modeling and supporting two literacy teachers to integrate authentic literature into their own literacy instruction and curriculum.
Mycoplasma pneumoniae-Associated Transverse Myelitis Presenting as Asymmetric Flaccid Paralysis
Authors: Salloum Shafee , Goenka Ajay , Ey Elizabeth
Published: September 2019

Acute transverse myelitis is a rare spinal cord inflammatory disorder that manifests as sudden onset of motor, sensory, and autonomic dysfunctions. Here, we report a case of acute transverse myelitis in a 13-year-old boy secondary to Mycoplasma pneumoniae infection. He presented with left facial palsy and contralateral upper extremity weakness without sensory or autonomic changes. The patient was diagnosed with transverse myelitis based on his magnetic resonance imaging findings, although his presentation was mainly motor dysfunction, which is more consistent with acute flaccid paralysis.

Authors: Liu Yanping , Hao Panpan
Published: September 2019

Coronary artery involvement in large-vessel arteritis is not uncommon, but rarely fatal. Here, we present a case of a young female with arteritis who was admitted to our hospital with acute myocardial infarction-induced cardiogenic shock. Imaging and laboratory results demonstrate that anticardiolipin antibody-related large-vessel arteritis is a possible cause of coronary ostial stenosis in patients with no other risk factors.
Research Progress of Hypertriglyceridemia and Coronary Heart Disease
Authors: Ji Yanyue , Bai Chunlin
Published: September 2019

At present, the relationship between hypertriglyceridemia (HTG) and coronary heart disease (CHD) is still uncertain. In recent years, many researchers have tried to clarify the relationship between HTG, atherosclerosis, and CHD. This article will review the relationship between HTG and CHD from the aspects of epidemiology, pathogenesis, and cardiovascular benefits of HTG treatment to further understand the relationship between the two. Dyslipidemia is closely related to the occurrence and development of the atherosclerotic cardiovascular disease. Elevated low-density lipoprotein cholesterol (LDL-C) has been recognized as an independent risk factor for cardiovascular events. Statins can effectively reduce LDL-C and reduce the incidence of cardiovascular events. HTG is the most common dyslipidemia in China, and the correlation between HTG and CHD deserves attention. Therefore, as for the progress of HTG and CHD in recent years, we will make a review on the relationship between HTC and CHD, the mechanism of atherosclerosis and the cardiovascular benefits of treatment, so as to further clarify the role and significance of triglyceride in the process of atherosclerosis and provide new ideas for the prevention an d treatment of CHD.

Balancing Hydraulic Flow and Fuel Injection Parameters for Low-Emission and High-Efficiency Automotive Diesel Engines
Authors: Di Blasio Gabriele , Beatrice Carlo , Ianniello Roberto , Pesce Francesco Concetto , Vassallo Alberto , Belgiorno Giacomo , Avolio Giovanni
Published: September 2019

The introduction of new light-duty vehicle emission limits to comply under real driving conditions (RDE) is pushing the diesel engine manufacturers to identify and improve the technologies and strategies for further emission reduction. The latest technology advancements on the after-treatment systems have permitted to achieve very low emission conformity factors over the RDE, and therefore, the biggest challenge of the diesel engine development is maintaining its competitiveness in the trade-off “CO2-system cost” in comparison to other propulsion systems. In this regard, diesel engines can continue to play an important role, in the short-medium term, to enable cost-effective compliance of CO2-fleet emission targets, either in conventional or hybrid propulsion systems configuration. This is especially true for large-size cars, SUVs and light commercial vehicles.

In this framework, a comprehensive approach covering the whole powertrain is of primary importance in order to simultaneously meet the performance, efficiency, noise and emission targets, and therefore, further development of the combustion system design and injection system represent important levers for additional improvements. For this purpose, a dedicated 0.5 dm3 single-cylinder engine has been developed and equipped with, a state-of-the-art Euro 6 combustion system, and an advanced common rail fuel injection system (FIS) offering higher flexibility in terms of injection strategy and higher quantity accuracy. Three injector nozzles with different hydraulic flow rates (HF) have been selected and employed for the overall combustion process optimization.

The optimization has been performed by means of an extensive DoE-based test campaign in which the engine and FIS operating parameters have been parametrized with the aim to carry out a proper combination in terms of HF and injection strategy. The results at partial load conditions evidence significant advantages in applying an advanced injection pattern, while the HF reduction can significantly improve the smoke emission and combustion noise without fuel consumption penalties. Therefore, a proper combination and optimization of the HF and injection strategy can provide low noise and engine-out smoke while maintaining the rated power performance targets.
Pressure Drop of Particulate Filters and Correlation with the Deposited Soot for Heavy-Duty Engines
Authors: Voutsi Ourania , Tsinoglou Dimitrios , Karamitros Dimitrios , Koltsakis Grigorios
Published: September 2019

Particulate filters are a widely used emission control device on heavy-duty diesel engines. The accumulation of particulate matter, mostly consisting of soot, inside the filter results in increased filter pressure-drop (backpressure). This increased backpressure has been used by the on-board control systems as trigger for regeneration procedures, which aim to actively oxidize the accumulated soot. However, it is known that passive soot oxidation during normal operation affects the correlation between backpressure and the deposited soot mass in filter. Therefore, the backpressure alone cannot be a reliable trigger for regeneration. In this work we highlight operating conditions with very poor correlation between backpressure and accumulated soot mass in filter and evaluate the possible root causes.

Experiments with several heavy-duty diesel engines and particulate filters were conducted on engine test bench. These experiments involved prolonged operation under conditions emulating real-world operation. Under certain conditions, the backpressure of the filter did not correlate with the accumulated soot mass: although the soot mass increased monotonically, reaching the regeneration soot mass limit, the measured backpressure corresponded to the backpressure of an almost clean filter. The quality of correlation was found to depend on the operating conditions, PM/NOx engine out emissions as well as on the type of filter used.

To investigate these complex interactions, we used an extensive experimental protocol to calibrate a physico-chemically informed mathematical model of the soot oxidation and the soot properties in the filter. We employed this model to investigate the possible reasons for the apparent lack of correlation between backpressure and accumulated soot mass. The simulation study confirmed the experimental findings: even minor passive soot oxidation may destroy the correlation between soot loading and filter backpressure. Moreover, simulation revealed the relative contribution of the following factors on the filter backpressure: microscopically, changes in the properties of the deposited soot, due to oxidation and compaction; macroscopically, non-uniform soot distribution inside the filter channels, due to transient flow and passive soot oxidation. Finally, simulations showed that the ratio of incoming soot from the engine to oxidizing soot in filter has a major impact on the potential to re-establish a correlation between soot loading and backpressure.
A Sampling and Conditioning Particle System for Solid Particle Measurements Down to 10 nm
Authors: Chasapidis Leonidas , Melas Anastasios D. , Tsakis Apostolos , Zarvalis Dimitrios , Konstandopoulos Athanasios
Published: September 2019

The measurement of vehicle particle number emissions and, therefore, regulation, necessitates a rigorous sampling and conditioning technology able to deliver solid emitted particles with minimum particle losses. European legislation follows a solid particle number measurement method with cutoff size at 23 nm proposed by the Particle Measurement Programme (PMP). Accordingly, the raw exhaust is sampled with constant volume, subsequently passes through a volatile particle remover (VPR), and finally is measured with a particle counter. Lowering the 23 nm cutoff size with current VPR technologies introduces measurement uncertainties mainly due to the high particle losses and possible creation of artefacts.

This study describes the development and evaluation of a sampling and conditioning particle system, the SCPS, specially designed for sub-23 nm solid particles measurement. The dilution process is achieved in two stages; the primary dilution is done with a porous tube while the secondary with an ejector diluter that also acts as a pump for the sampling flow. The SCPS offers flexibility in terms of dilution ratio (DR) which is real-time calculated with an algorithm based on a differential pressure measurement across an orifice. Between the two dilution stages, a catalytic stripper removes volatile material with high efficiency. The SCPS evaluation includes the DR calculation algorithm testing, the stability of DR during transient engine conditions, the volatile particle removal efficiency with tetracontane particles, the solid particle penetration efficiency with polydisperse CAST-generated soot particles, and the measurement of sub-23 nm particles emitted by a diesel engine. The high stability of the DR in combination with >99% volatile particle removal and a cutoff size (d50) at 7.5 nm suggest that the SCPS may deliver solid emitted particles for robust particle number measurements down to at least 10 nm.
Design of a Hybrid Power Unit for Formula SAE Application: Packaging Optimization and Thermomechanical Design of the Electric Motor Case
Authors: Mangeruga Valerio , Giacopini Matteo , Barbieri Saverio Giulio , Berni Fabio , Mattarelli Enrico , Rinaldini Carlo
Published: September 2019

This paper presents the development of a parallel hybrid power unit for Formula SAE application. In particular, the system is made up of a brand new, single-cylinder 480 cc internal combustion engine developed on the basis of the Ducati “959 Superquadro” V90 2-cylinders engine. The thermal engine is assisted by a custom electric motor (30 kW), powered by a Li-Ion battery pack. The performance of the ICE has been optimized through CFD-1D simulation (a review of this activity is reported in a parallel paper). The main design goal is to get the maximum amount of mechanical energy from the fuel, considering the car typical usage: racing on a windy track. The Ducati “959 Superquadro” engine is chosen because of its high power-to-weight ratio, as well as for its V90 2-cylinder layout. In fact, the vertical engine head is removed and it is subsequently replaced by the electric motor directly engaged to the crankshaft using the original valvetrain transmission chain, thus achieving a very compact package. The mechanical behaviour of the original chain is investigated for this purpose. A specific electric motor case is then designed and manufactured via Additive Manufacturing technology, in order to include the chain housing, the electric motor cooling system and the lubrication system. Furthermore, the case flange is designed to perfectly fit to the original engine deck in order to allow the engine cooling circuit to match with the electric motor cooling circuit. Several types of circuit layout - around the stator - are analysed via CFD simulations comparing pressure drop and heat transfer coefficients. Finally, a thermo-structural analysis is performed in order to assess the mechanical strength of the electric motor case.

Tradução e Hermenêutica
Authors: Colares Adriana Almeida
Published: September 2019

A palavra “hermenêutica” pode fazer referência tanto à prática (em que o tradutor é um intérprete) e, de acordo com a definição de George Steiner e Antoine Berman, quanto à crítica de tradução. O objetivo desse artigo é esclarecer essa definição. De acordo com o que Antoine Berman a apresenta, a hermenêutica em seu sentido clássico legitima as traduções etnocêntricas. Praticada desde a Antiguidade até o Período Medieval, essa visão clássica da hermenêutica (também endossada por filósofos como Paul de Man), sugere que o significado do texto existe além do seu suporte material. De modo inverso, de acordo com George Steiner, a tradução é um “caminho hermenêutico” que deve considerar cada aspecto do texto além das considerações morais, históricas e contextuais. Para se produzir um texto equivalente na língua alvo, a tradução – concebida tanto como prática, como crítica – deve considerar todos os aspectos que fazem um texto único, como prosódia, gramática e estilo. Desse ponto de vista, a hermenêutica se revela como uma poética da tradução.

Secondary organic aerosol formation from smoldering and flaming combustion of biomass: a box model parametrization based on volatility basis set

Abstract. Residential wood combustion remains one of the most important sources of
primary organic aerosols (POA) and secondary organic aerosol (SOA)
precursors during winter. The overwhelming majority of these precursors have not been traditionally considered in regional models, and only recently were lignin pyrolysis products and polycyclic aromatics identified as the
principal SOA precursors from flaming wood combustion. The SOA yields of
these components in the complex matrix of biomass smoke remain unknown and
may not be inferred from smog chamber data based on single-compound systems.
Here, we studied the ageing of emissions from flaming and
smoldering-dominated wood fires in three different residential stoves,
across a wide range of ageing temperatures (−10, 2
and 15 ∘C) and emission loads. Organic gases (OGs) acting as SOA
precursors were monitored by a proton-transfer-reaction time-of-flight mass
spectrometer (PTR-ToF-MS), while the evolution of the aerosol properties
during ageing in the smog chamber was monitored by a high-resolution
time-of-flight aerosol mass spectrometer (HR-ToF-AMS). We developed a novel
box model based on the volatility basis set (VBS) to determine the
volatility distributions of the oxidation products from different precursor
classes found in the emissions, grouped according to their emission pathways
and SOA production rates. We show for the first time that SOA yields in
complex emissions are consistent with those reported in literature from
single-compound systems. We identify the main SOA precursors in both flaming
and smoldering wood combustion emissions at different temperatures. While
single-ring and polycyclic aromatics are significant precursors in flaming
emissions, furans generated from cellulose pyrolysis appear to be important
for SOA production in the case of smoldering fires. This is especially the
case at high loads and low temperatures, given the higher volatility of
furan oxidation products predicted by the model. We show that the oxidation
products of oxygenated aromatics from lignin pyrolysis are expected to
dominate SOA formation, independent of the combustion or ageing conditions,
and therefore can be used as promising markers to trace ageing of biomass
smoke in the field. The model framework developed herein may be
generalizable for other complex emission sources, allowing determination of
the contributions of different precursor classes to SOA, at a level of
complexity suitable for implementation in regional air quality models.
Depth habitat of the planktonic foraminifera Neogloboquadrina pachyderma in the northern high latitudes explained by sea-ice and chlorophyll concentrations
Authors: Greco Mattia , Jonkers Lukas , Kretschmer Kerstin , Bijma Jelle , Kucera Michal
Published: September 2019

Abstract. Neogloboquadrina pachyderma is the dominant planktonic foraminifera species in the polar
regions. In the northern high-latitude ocean, it makes up more than 90 %
of the total assemblages, making it the dominant pelagic calcifier and
carrier of paleoceanographic proxies. To assess the reaction of this species
to a future shaped by climate change and to be able to interpret the
paleoecological signal contained in its shells, its depth habitat must be
known. Previous work showed that N. pachyderma in the northern polar regions has a highly
variable depth habitat, ranging from the surface mixed layer to several
hundreds of metres below the surface, and the origin of this variability
remained unclear. In order to investigate the factors controlling the depth
habitat of N. pachyderma, we compiled new and existing population density profiles from
104 stratified plankton tow hauls collected in the Arctic and the North
Atlantic oceans during 14 oceanographic expeditions. For each vertical
profile, the depth habitat (DH) was calculated as the abundance-weighted
mean depth of occurrence. We then tested to what degree environmental
factors (mixed-layer depth, sea surface temperature, sea surface salinity,
chlorophyll a concentration, and sea ice concentration) and ecological
factors (synchronized reproduction and daily vertical migration) can predict
the observed DH variability and compared the observed DH behaviour with
simulations by a numerical model predicting planktonic foraminifera
distribution. Our data show that the DH of N. pachyderma varies between 25 and 280 m
(average ∼100 m). In contrast with the model simulations,
which indicate that DH is associated with the depth of chlorophyll maximum,
our analysis indicates that the presence of sea ice together with the
concentration of chlorophyll a at the surface have the strongest influence
on the vertical habitat of this species. N. pachyderma occurs deeper when sea ice and
chlorophyll concentrations are low, suggesting a time-transgressive response
to the evolution of (near) surface conditions during the annual cycle. Since
only surface parameters appear to affect the vertical habitat of N. pachyderma, light or
light-dependant processes might influence the ecology of this species. Our
results can be used to improve predictions of the response of the species to
climate change and thus to refine paleoclimatic reconstructions.

Published: September 2019

Abstract. The intertidal bivalve Katelysia rhytiphora, endemic to south Australia and Tasmania,
is used here for pulsed Sr-labelling experiments in aquaculture experiments
to visualize shell growth at the micro- to nanoscale. The ventral margin
area of the outer shell layer composed of (i) an outermost outer shell layer
(oOSL) with compound composite prismatic architecture with three
hierarchical orders of prisms and (ii) an innermost outer shell layer (iOSL)
with crossed-acicular architecture consisting of intersecting lamellae
bundles. All structural orders in both layers are enveloped by an organic
sheath and the smallest mineralized units are nano-granules. Electron
backscatter diffraction reveals a strong preferred orientation of the
aragonite c axes perpendicular to the growth layers, while the a and b axes
are scattered within a plane normal to the local growth direction and
>46 % twin grain boundaries are detected. The Young's modulus
shows a girdle-like maximum of elastically stiffer orientations for the
shell following the inner shell surface. For 6 d, the bivalves were subjected twice to seawater with an increased
Sr concentration of 18× mean ocean water by dissolving 144 µg g−1 Sr (159.88 Sr∕Ca mmol ∕ mol) in seawater. The pulse
labelling intervals in the shell are 17× (oOSL) and 12× (iOSL) enriched in
Sr relative to the Sr-spiked seawater. All architectural units in the shell
are transected by the Sr label, demonstrating shell growth to progress
homogeneously instead of forming one individual architectural unit after the
other. Distribution coefficients, DSr ∕ Ca, for labelled and unlabelled shells are similar to shell
proportions formed in the wild (0.12 to 0.15). All DSr ∕ Ca values are lower than
values for equilibrium partitioning of Sr in synthetic aragonite.

Abstract. Land use and land cover (LULC) maps in many areas have been used by companies, government offices, municipalities, and ministries. Accurate classification for LULC using remotely sensed data requires State of Art classification methods. The SNAP free software and ArcGIS Desktop were used for analysis and report. In this study, the optical Sentinel-2 images were used. In order to analyze the data, an object-oriented method was applied: Supported Vector Machines (SVM). An accuracy assessment is also applied to the classified results based on the ground truth points or known reference pixels. The overall classification accuracy of 83,64% with the kappa value of 0.802 was achieved using SVM. The study indicated that of SVM algorithms, the proposed framework on Sentinel-2 imagery results is satisfactory for LULC maps.

RESEARCH ON QUALITY SUPERVISION AND SPOT CHECKS TECHNOLOGY FOR NATIONWIDE LARGE-SCALE TOPOGRAPHIC MAPS IN CHINA
Authors: Ma W. , Zhao Y. , Zhang P. , Dong S. , Luo F. , Liu C. , Wu X.
Published: September 2019

Abstract. Large-scale Topographic Maps (LST-Maps) play an important role in China, so their quality is of great importance. In order to guarantee the quality of the survey and mapping achievements, China has been implementing a supervision and inspection system. There are relatively big differences in the content, mode of production and demands for application of the LST-Maps all over the country, making it difficult for current informatization level of supervision and traditional methods of quality control to become fair and efficient. The existing operational mode, sampling means, and technical standards of inspection applied in supervision are not entirely suitable for the needs in quality supervision and inspection of LST-Maps. In face of the abovementioned contradictions and problems, the research has combined the requirements of quality supervision and spot checks of all levels. Various achievements such as an index system, technical means, inspection procedures and a software platform have been created, and they are widely used in the quality supervision and spot checks of national and provincial LST-Maps over the past three years.
A MULTI-PURPOSE BENCHMARK FOR PHOTOGRAMMETRIC URBAN 3D RECONSTRUCTION IN A CONTROLLED ENVIRONMENT
Authors: Özdemir E. , Toschi I. , Remondino F.
Published: September 2019

Abstract. This paper presents a novel multi-purpose benchmark for assessing the performance of the entire image-based pipeline for 3D urban reconstruction and 3D data classification. The proposed benchmark is called “3DOMcity” photogrammetric contest and is publicly available at https://3dom.fbk.eu/3domcity-benchmark. Compared to previous benchmark initiatives, the innovative aspects introduced by 3DOMcity are threefold. First, it covers the entire 3D reconstruction pipeline, including image orientation, dense image matching, point cloud classification and 3D building reconstruction. Second, the performance assessment is performed within a metrological context. Finally, the provided datasets offer 2D and 3D data collected at a very high spatial resolution. Furthermore, the benchmark is multi-purpose since it involves a multiplicity of tasks, that can be either performed independently from each other’s, or grouped together. The contributions of this paper are (i) the presentation of the novel benchmark dataset and corresponding reference data, (ii) the description of the multi-purpose benchmark tasks and evaluation procedures, and (iii) the discussion of first results of image orientation, dense image matching and classification.

Staff reported a steep learning curve, with competing demands to build relationships, engage youth, and show results. Lessons learned may help shape activities that other youth development programs may consider in similar efforts.
Psychological Engagement and Behavioral Activity Participation As Predictors of Positive Youth Development
Authors: Ramey Heather L. , Lawford Heather L. , Rose-Krasnor Linda
Published: September 2019

Youth’s structured (e.g., sports) and unstructured (e.g., socializing) activities are key contexts for positive development. Both behavioral participation (e.g., frequency) and elements of psychological engagement (e.g., enjoyment, challenge) in programs and activities have been linked to components of youth development. We tested a model in which both psychological engagement and behavioral participation in activities predicted overall positive youth development in older adolescent and emerging adult samples (Sample 1, n = 235, mean age = 18.7 years, SD = 1.4 years, 67.7% female; Sample 2, n = 186, mean age = 20.0 years, SD = 2.1 years, 68.8% female). In the first known study to include behavioral participation and multidimensional psychological engagement in predicting the Five Cs of positive youth development, we found that greater psychological engagement, but not behavioral participation, was related to higher positive youth development across samples and different activity types. Findings suggest that promoting youth’s psychological engagement in programs and other activities, rather than just their physical presence, may be advantageous for strengthening positive youth development.

O presente trabalho visa analisar o direito ao território tradicional Panambi Lagoa Rica dos Guarani-Kaiowá, em Mato Grosso do Sul. Nessa análise, busca-se demonstrar como se configurou a dispersão territorial protagonizada por essas etnias mediante a criação de reservas indígenas a partir da atuação do Serviço de Proteção ao Índio (SPI), entre 1915 a 1928. Dentre os motivos que estruturam as reservas indígenas citam-se os interesses coloniais e agrários em virtude de integrarem a diáspora indígena no Estado. Coloca-se que por razões históricas, a terra Panambi Lagoa Rica se torna um direito inerente ao território tradicional. Destaca-se que a decisão judicial que reconhecia o território como território indígena foi anulada, no ano de 2016, não efetivando assim, esse direito constitucional, acarretando o enfraquecimento dos laços territoriais étnicos. Diante desse contexto, esse estudo se fundamenta na dispersão territorial indígena, a fim de justificar o direito ao território tradicional. Aplica-se à pesquisa o método exploratório, bibliográfico e qualitativo no convívio com o texto constitucional de 1988.

We conducted stable isotope (δ13C and δ15N) and gut content analyses to understand habitat use of juvenile reef fishes (Lethrinus lentjan, Lutjanus russellii, and Epinephelus coioides), particularly the influence of spatial habitat
structure along seagrass–mangrove continua. Sampling was conducted in Setiu Lagoon, located in the southern waters of the South China Sea (Malaysia). Gut content analysis indicated that the focal fishes preyed mainly on benthic invertebrates and other smaller fishes; these were used
as potential prey items for isotopic tracers to track fish habitat use. Stable isotope analyses highlighted that the juvenile reef fishes were highly associated with seagrass beds as feeding grounds; however, site-specific analyses suggest differences in fish feeding habitats. The juvenile
fishes, particularly large juveniles, preyed in both mangrove and seagrass areas from the central lagoon, whereas all juveniles showed preferential foraging within seagrass meadows in the nearby lagoon mouth. Furthermore, the mean stable isotope values of muscle tissue differed among fish
size classes, indicating their ontogenetic habitat/diet shifts, especially for L. lentjan and E. coioides. This study provides important information to support current efforts in protecting and preserving mangroves and seagrasses as crucial nursery habitats for juvenile reef
fishes from the anthropogenic activities influencing Setiu Lagoon.
Eclipse in Rwanda as Remembering in Pyschosocial Poetics of Trauma
Authors: Onuoha Onyekachi
Published: September 2019

Trauma exists in a synthetic mode of the referential and this is the underlying temperament in Eclipse in Rwanda. The genocide that is chronicled in the narratives of the Nigerian Civil war as recreated in Joe Ushie’s Eclipse in Rwanda foreshadows the pogrom in the mid 90s. Using Cathy Caruth’s concept of trauma as a theoretical framework, this paper examines Eclipse in Rwanda as remembering in psychosocial poetics of trauma. This paper further explicates Eclipse in Rwanda as a text of memory, which poetically captures the trauma and foreshadows the social construction of natives/ non-natives in Africa at large and in Nigeria in particular. Through the poems analysed in this paper, our findings show that Tutsis’ genocide is a poetic fulcrum for the poet to pensively recall the Nigerian Civil War and other hotspots/ narratives of politically motivated violence against fellow citizens. Eclipse in Rwanda attempts to entrench the memories of the dead in us through the poetics of remembering and by so doing indict the collective consciences of the society.
Porter’s Diamond Approaches and the Competitiveness Web
Authors: Vlados Charis
Published: September 2019

This study explores Porter’s diamond of national competitiveness, by critically examining both the analytical virtues, the extensions, and the criticisms it has received over time. The aim is to analyse the stage in which the study of the diamond is currently in, about twenty years after the introduction of M. Porter, suggesting that its analytical contribution focusing on the industrial dynamics (meso-competitiveness) is still relevant even though significant analytical repositioning and improvements are possible. This research attempts to integrate a set of evolutionary socioeconomic dimensions into the “diamond’s” analytical perspective, ending up with a proposed “competitiveness web” conceptual model.

Atualmente, as mudanças organizacionais vêm ganhando cada vez mais espaço, pois as empresas estão investindo em mudanças a fim de obter melhorias e aumentar a sua competitividade no mercado atual. No entanto, uma análise da literatura sobre o assunto mostra que, apesar das mudanças serem necessárias e constantes, seu nível de sucesso ainda é pequeno. Portanto, é necessário que as organizações se preocupem em realizar uma gestão adequada da mudança para garantir seu sucesso. Assim o objetivo do presente trabalho é o de relatar um estudo de caso do processo de gestão de mudança em uma empresa do ramo de distribuição de combustíveis com a implementação de um Centro de Serviços Compartilhados (CSC). Primeiramente, foi feita uma revisão bibliográfica da literatura sobre gestão de mudanças e mudança organizacional. Em segundo lugar, a revisão focou os poucos artigos sobre Centro de Serviços Compartilhados. É apresentado o processo de gestão da mudança na empresa a fim de comparar com a revisão de literatura sobre gestão de mudanças com o que foi relatado no estudo de caso. O caso de sucesso da empresa apresenta indícios de que o uso das técnicas presentes na literatura e as boas práticas de gerenciamento de mudanças podem ser um fator de sucesso para implementação de projetos em empresas do setor de Óleo e Gás, mais especificamente, da área de distribuição e comercialização de combustíveis.

Felipe é um experiente gestor de projetos, reconhecido por seu costumeiro sucesso ao gerenciar projetos que envolvam mudanças. Agora, ele é convidado a assumir um desafio na multinacional Zubarah Shipping Express, empresa de navegação com sede no Qatar, que possui três escritórios no Brasil. Felipe atuará no escritório de Santa Catarina, onde seu grande desafio será implementar um projeto de mudança, que é exigido pela diretoria da empresa mas que, na visão da maioria dos colaboradores, não possui nenhuma necessidade e pode, inclusive, prejudicar o atendimento. O objetivo do caso é estimular a discussão sobre gestão de projetos, liderança, habilidades e gestão de mudanças, por meio da busca por possíveis soluções para o caso apresentado. Sugere-se aplicação para alunos de graduação ou especialização lato sensu que estudem assuntos relacionados à liderança, gestão de projetos e gestão de mudanças.

Published: September 2019

O objetivo deste estudo foi analisar o efeito da Governança de Projetos e da Gestão da Realização de Benefícios na Estratégia Organizacional, potencializado por indicadores de desempenho de projetos. Um modelo estrutural com relações entre Governança de Projetos, Gestão da Realização de Benefícios, Sucesso de Projetos, Estratégia Organizacional e efeito moderador de indicadores de desempenho de projetos foi proposto. A amostra do estudo consistiu em 113 respondentes que atuam profissionalmente com gestão de projetos. As análises foram realizadas por meio da Modelagem de Equações Estruturais, com estimação pelo método dos “Mínimos Quadrados Parciais”. Os resultados da pesquisa indicaram relações significativas entre as variáveis latentes, com exceção da relação entre Governança de Projetos e Sucesso dos Projetos, também foi confirmado o efeito moderador que os indicadores de desempenho de projetos exercem na relação entre o Sucesso de Projetos e a Estratégia Organizacional. Ao final do trabalho é proposto um modelo de estrutura de Governança de Projetos direcionada à Estratégia Organizacional sob o contexto da Gestão da Realização de Benefícios e utilizando indicadores de desempenho de projetos em uma perspectiva multidimensional envolvendo todo o contexto estratégico da organização.

Published: September 2019

Background: The static headspace technique is one of the most popular techniques for residual solvent analysis and dimethyl sulfoxide (DMSO) and N,N-dimethylformamide (DMF) are widely use as the dissolution media. Objective: This study aims to establish ethyl lactate (EL), a solvent with low toxicity and less environmental impact, as an alternative dissolution medium to DMSO and DMF for the static headspace analysis of toxic residual solvents in food, cosmetics, and similar complex organic matrices. Methods: Samples (a sample of dietary supplement and two samples each of cosmetics and household products) spiked with benzene, carbon tetrachloride, 1,2-dichloroethane, 1,1-dichloroethene, and 1,1,1-trichloroethane were dissolved in EL, DMSO, and DMF. Static headspace GC/MS and the standard addition method were used to detect and quantify the residual solvents. Results: The dissolution and dispersion of these samples, especially the ones which were water-insoluble, were better than those in DMSO and DMF. The recoveries, except that of benzene in an aerosol spray, in EL ranged from 77 to 110%. The relative SDs in EL ranged from 2.5 to 11% and were better or equivalent to those in DMSO and DMF. Conclusions: EL was suitable as the dissolution medium for such samples, which may contain large amounts of organic solvents or various ingredients, in static headspace GC/MS analysis of residual solvents.
