Published: October 2019

This study analyses the extent to which faculty use the technological resources that make up their Learning Ecologies to encourage their teacher professional development. The interest of this research is the growing impact of Learning Ecologies as a framework to examine the multiple learning opportunities provided by the complex digital landscape. Global data referred to the use of technological resources grouped in three dimensions (Access, Search and Information Management resources, Creation and Content Editing resources, and Interaction and Communication resources) has been identified. In addition, the influence of different variables such as gender, age, years of teaching experience and the branch of knowledge were also examined. The methodology used has been quantitative through a survey. The sample consisted of 1,652 faculty belonging to 50 Spanish universities. To meet the aim of the study, descriptive and inferential analysis (ANOVA) were carried out. On the one hand, it is noted a moderate use of technological resources for professional development and, on the other hand, significant differences are observed on all variables analysed. The results warn of the need to promote, both at individual and institutional level, more enriched Learning Ecologies, in such a way that each teacher can take better advantage of the learning opportunities, provided by the networked society.

En este estudio se analiza en qué medida el profesorado universitario utiliza los recursos tecnológicos que configuran sus Ecologías de Aprendizaje para propiciar su desarrollo profesional como docentes. El interés de esta investigación radica en el creciente impacto del constructo de las Ecologías de Aprendizaje como marco para examinar e interpretar las múltiples oportunidades de aprendizaje que ofrece el complejo panorama digital actual. Además de identificar los datos globales referidos al uso de los recursos tecnológicos agrupados en tres dimensiones (recursos de acceso, búsqueda y gestión de la información, recursos de creación y edición de contenido, y recursos de interacción y comunicación), también se examina la influencia de diferentes variables como el género, la edad, los años de experiencia docente y la rama de conocimiento. La metodología empleada ha sido de corte cuantitativo a través de encuesta. La muestra está compuesta por 1.652 profesores pertenecientes a 50 universidades españolas. Para dar respuesta al objetivo del estudio se llevaron a cabo análisis descriptivos e inferenciales (ANOVA). Se constata un empleo moderado de los recursos tecnológicos para el desarrollo profesional y, además, se observan diferencias significativas en función de las variables analizadas. Los resultados alertan de la necesidad de fomentar, tanto a nivel individual como institucional, Ecologías de Aprendizaje más enriquecidas, de manera que cada docente pueda aprovechar mejor las posibilidades de aprendizaje que ofrece la sociedad en red.
Objets puis systèmes techniques au programme : éclairages pour une discussion de leurs statuts et de leurs fonctions dans l’enseignement
Authors: Lebeaume Joël
Published: October 2019

Avec une perspective historique, l’article rend compte de l’extension des objets techniques aux systèmes techniques dans l’enseignement technologique. Il analyse le processus de leur scolarisation et de leur didactisation dont la fonction d’usage est alors détournée pour répondre aux contraintes et exigences de la conception de l’enseignable, de l’apprenable et de l’évaluable en situation collective. À cet égard, est faite l’hypothèse que la forme scripturale des savoirs scolaires assure cette transformation de la fonction d’usage hors et dans l’école. Est ainsi ouverte une discussion des implications didactiques à l’échelle des constructions curriculaires et des enseignements scolaires.

Faire problématiser des élèves de CE2 en histoire à partir de témoignages
Authors: Doussot Sylvain , Fink Nadine
Published: October 2019

La conception et la mise en œuvre d’une séquence (en CE2) portant sur la mémoire et l’histoire de la vie quotidienne au XX e  est analysée sous le prisme de la potentialité didactique des témoignages pour développer la pensée critique des élèves par une démarche d’enquête. Les témoignages recueillis par les élèves sont confrontés entre eux et aux idées des élèves, pour mettre en rapport points de vue des témoins et des élèves, mais aussi mémoire individuelle et mémoire collective. Un processus de conceptualisation historique s’engage et on observe des difficultés à mener conjointement la critique de l’interprétation du passé et celle des sources.
Can metabolic thresholds be used as exercise intensity markers in adult men with obesity – fat burn points used as an exercise marker
Authors: Peric R. , Nikolovski Z.
Published: October 2019

We aimed to determine the exercise intensity eliciting the highest (FATmax) and the lowest (FATmin) fat oxidation rate in sedentary men with obesity and to examine if these intensities correlate with their individual aerobic (AeT) and anaerobic (AnT) thresholds, respectively. Nineteen obese males performed breath-by-breath analysis to assess maximal oxygen consumption (VO2max) and to calculate their fat oxidation rate. Pearson correlation coefficient (r), coefficient of determination (R
2) and paired t-test were used to evaluate VO2 at AeT and at FATmax and VO2 at AnT and at FATmin, respectively. FATmax and AeT occurred at 42.80±2.68% of VO2max and 43.02±2.73% of VO2max, while FATmin and AnT occurred at 53.40±3.65% of VO2max and 53.38±3.65% of VO2max, respectively. A high correlations were found between intensities matching FATmax and AeT (r=0.86, P<0.01) and those at FATmin and at AnT (r=0.99, P<0.01). The existing correlations suggest that metabolic thresholds may be used as exercise intensity markers assuring more tailored exercise approach in men with obesity.

Published: October 2019

Aflatoxin M1 is a derivate of aflatoxin B1 and an important contaminant of milk and dairy products. This systematic review and meta-analysis was conducted on relevant Persian and English original articles in national and international databases with no time limits until 1 January 2018. In total 605 articles were found among which 70 articles met the inclusion criteria for meta-analysis. The prevalence (95% confidence interval (CI)) and mean concentration (95% CI) of aflatoxin M1 was found to be 64% (53-75%) and 39.7 ng/l (31.9-47.4 ng/l) in raw milk, 95% (89-98%) and 62.3 ng/l (40.6-84 ng/l) in pasteurised milk, 71% (56-84%) and 60.1 ng/l (30.9-89.3 ng/l) in sterilised milk, 59% (20-93%) and 5.5 ng/l (3.3-7.7 ng/l) in breast milk and 72% (61-81%) and 82.3 ng/kg (63.7-100.9 ng/kg) in dairy products. In general, 9% (4-16%) of milks and 10% (4-17%) of dairy products had aflatoxin M1 in concentrations exceeding the permitted level of Iranian standards (500 ng/l). Based on the maximum permitted aflatoxin M1 concentration in standards of Europe (50 ng/l), these percentages increase to 25% (18-32%) for milks and 18% (9-29%) for dairy products. According to the results, further control and preventive measures should be applied on livestock feeds because decreased aflatoxin B1 contamination at this level results in decreased aflatoxin M1 in milk and dairy products.
Hullform & Hydrodynamic Considerations in the Design of the UK Future Aircraft Carrier (CVF)
Authors: Campbell-Roddis M E
Published: October 2019

An overview is provided of the manner in which hydrodynamic and hullform-related design considerations were addressed in the development of the BAE SYSTEMS team’s design proposal for the UK Future Aircraft Carrier (CVF). It also outlines how broader design considerations such as aviation, survivability and supportability requirements influenced these aspects of the design. A summary is also provided of some of the more detailed requirements development, option assessment and performance evaluation work that has been undertaken. The aircraft carrier designs discussed in this paper correspond to the BAE SYSTEMS team’s final design submission as it stood in January 2003, at the time it was discontinued by the UK Ministry of Defence, in favour of the rival Thales / BMT team design that has since been developed into the UK Royal Navy’s new ‘Queen Elizabeth’ class aircraft carrier. This final BAE SYSTEMS design submission consisted of two distinct design variants - one configured to operate a CTOL-based air group, the other configured to accommodate a STOVL air group. Both variants were based on a common ‘core’ ship design. The discussion presented in this paper is applicable to both variants.

This paper was originally written for presentation at the June 2003 Royal Institution of Naval Architects ‘Warships 2003 - Air Power at Sea’ Conference. However, it was withheld from publication at the request of the UK Ministry of Defence, due to sensitivity surrounding the UK Aircraft Carrier project at that time. Following re-appraisal in June 2016, the UK Ministry of Defence has now authorised publication of this paper in full. The paper is presented here in its original (2003) form, with Section 2 added to provide historical perspective (given the passage of time).
HYDRODYNAMIC PERFORMANCES OF WARPED HARD CHINE DISPLACEMENT HULL FORM
Authors: Begovic E , Bertorello C , Bove A , Pennino S
Published: October 2019

The results of experimental tests relative to resistance, seakeeping and roll decay of a warped hard chine hull form, suitable for large yacht design are reported. To better investigate the effect of hard chine, a round bilge identical model has been tested. Resistance tests have been performed at FV ranging from 0.90 to 4.14, for three different LCG. Results for resistance, sinkage and trim are given. For the most realistic condition dynamic wetted surface is determined separating pressure and whisker spray areas to allow reliable full scale powering predictions. For the same static trim condition, heave, pitch and accelerations have been measured for head sea at FV = 1.35 and 1.89 in regular waves for different /Lratios at constant wave steepness H/ = 1/50. Roll decay at five speeds and roll at zero speed were investigated. The reported data and considerations represent a reference for the implementation of hard chine hull form in the design of displacement and semidisplacement large yachts.
A FORMULA PROPOSED FOR ESTIMATING THE LONGITUDINAL EXTENT OF RAKING DAMAGE TO THE HULL OF A HIGH-SPEED VESSEL
Authors: Kanifolskyi O O
Published: October 2019

The old and new requirements of the High Speed Craft Code, and the methods used by some researchers for calculating the damage length for a ship’s hull, are considered in this paper. Damage occurs more often in small vessels than in large vessels. Collisions between ships and ship grounding are two of the main reasons for the loss of ships. The damage to a vessel is determined for the worst case scenario. Long and narrow ("raking") damage, which absorbs the kinetic energy of the vessel, is the worst-case scenario. Small high speed craft were selected for analysis. This paper describes the requirements of the High Speed Craft Code related to high-speed vessels. Small semi planing vessels are a category of high-speed vessels, operated at volume Froude numbers between 1 and 3. The formula for calculating the length of the possible hull damage should take into account the material, the thickness of the plating, the width of the damage, the vessel's speed and its displacement. This paper proposes such a formula for the maximum possible length of the hull damage, which has been calculated using different methods. The formula is proposed for small high speed vessels, but it is possible to use the same formula for other types of ships.
THE RE-EXAMINATION OF IOR YACHT PERFORMANCE – OBTAINING DATA FOR VELOCITY PREDICTION AND SENSITIVITY TO DATA ACCURACY AND QUALITY
Authors: Boyd S W
Published: October 2019

The International Offshore Rule (IOR) provided a handicap system for racing yachts in the 1970s, 80s and 90s. It was accepted worldwide and many of the famous yacht designers of today made their name in the high profile events that took place under this rule. There is a large body of commentary and opinion regarding yachts of this era, in which the rule allowed the designer to explore the design space in search of designs that rated lower than their size. Yachts, particularly in the early IOR era, were designed through experience, knowledge of the rule and inherent talent. Computing power was low and the subject of velocity prediction was in its infancy. This paper examines a method of undertaking a velocity prediction of yachts of this era using data provided by the designers, namely lines plans and rating certificates. A performance sensitivity analysis is conducted examining aspects such as measured versus sailing trim, lack of geometric data, influence of waves and sail configurations. The results show that subtle changes in input data, associated with the yacht, can be measured in terms of performance. This will allow for the future comparison of fleets of boats and provide some data to confirm or contradict the sailing community narrative regarding IOR yacht performance.
RELIABILITY ENGINEERING IN SURVEY AND MAINTENANCE OF SAILING YACHT RIGS
Authors: Orlando M , Boote D , Faloci F
Published: October 2019

Modern sailing boats are designed to reach high speeds, however, the main challenge is to achieve high technical performance while also maintaining good reliability to provide a high level of safety. Recently, Classification Societies and statutory requirements have given more attention to the certification of spars and rigging, in fact the increasing size of sailing superyachts, their rising costs and a growing focus on safety have led designers, shipyards and ship owners to no longer underestimate the importance of this issue, which, after sinking, represents the greatest potential risk of life threatening for crewmembers and large economic losses for the owner.

The Pareto Principle states that, for many events, 20% of input (resources, effort, etc.) accounts for 80% of output (result, rewards, etc.). The aim of this work is, in fact, to investigate on the 20% of the rig elements that cause the 80% of rig failures and to select the best maintenance program to reduce these failures. This is important because useless maintenance is neither time nor cost effective: by selecting and maintaining the most important rig elements there will be a great safety improvement without wasting time focusing on those unnecessary items whose failure doesn’t comport a big loss in the yacht operability and that could be easily replaced once they break. The aim of the present investigation is then to set up a rational method to optimize the verification procedure of a complex rig system.

In the first phase of this study a statistical analysis of a significant dismasting database has been collected and examined in order to statistically highlight the key elements related to rigs reliability. In the second phase some representative Southern Wind yachts have been assumed as study cases to simulate rig elements failures with a CFD/FEM integrated software. Finally a FMECA and a risk analysis and element prioritisation have been performed.

The provided results can be helpful to Classification Society to plan a set of different rules requirements and to select the most critical items that will be surveyed and tested by a class surveyor.

Authors: Magherini M , Meredith Hardy A , Thoumazeau A
Published: October 2019

The end of 2018 saw the delivery of the motor yacht Bravo Eugenia. She is built by Oceanco based on the LIFE platform developed in collaboration with Lateral Naval Architects. This study defines the LIFE platform (i.e. Long, Innovative, Fuel efficient, Eco conscious) its key features and outlines its fundamental design pillars. The relative merits of main parameters are assessed against a typical similar sized yacht by use of baseline fleet data. LIFE’s low weight in relation to length and reduced powering requirements combined with a hybrid propulsion system result in a virtuous circle at which the centre is the single tier engine room. The benefits of the single tier layout such as the higher flexibility in designing the accommodation spaces and the improved balance between technical and luxury areas are outlined. In this context, various designers’ LIFE platform interpretations are provided as examples for discussion. The LIFE hybrid propulsion system is presented and the various modes of operations for which the hybrid system is conceived are discussed.

Published: October 2019

Recent advances in pervasive technologies, such as wireless, ad hoc networks, and wearable sensor devices, allow the connection of everyday things to the Internet, commonly denoted as the Internet of Things (IoT). The IoT is seen as an enabler to the development of intelligent and context-aware services and applications. However, handling dynamic and frequent context changes is a difficult task without a real-time event/data acquisition and processing platform. Big data technologies and data analytics have been recently proposed for timely analyzing information (i.e., data, events) streams. The main aim is to make users' life more comfortable according to their locations, current requirements, and ongoing activities. In this article, combining IoT techniques and Big data technologies into a holistic platform for continuous and real-time health-care data monitoring and processing is introduced. Real-testing experiments have been conducted and results are reported to show the usefulness of this platform in a real-case scenario.
Fuzzy Probabilistic Ontology Approach
Authors: Riali Ishak , Fareh Messaouda , Bouarfa Hafida
Published: October 2019

In spite of the undeniable success of the ontologies, where they have been widely applied successfully to represent the knowledge in lots of real-world problems, they cannot represent and reason with uncertain knowledge which inherently appears in most domains. To cope with this issue, this article presents a new approach for dealing with rich-uncertainty domains. In fact, it is mainly based on integrating hybrid models which combine both fuzzy logic and Bayesian networks. On the other hand, the Fuzzy multi-entity Bayesian network (FzMEBN) proposed as a hybrid model which enhances the classical multi-entity Bayesian network using fuzzy logic, it can be used to represent and reason with probabilistic and vague knowledge simultaneously. Thus, as a language belongs to the proposed approach, this study proposes a promising solution to overcome the weakness of the Probabilistic Ontology Web Language (PR-OWL) based on FzMEBN to allow dealing with vague and probabilistic knowledge in ontologies. The proposed extension is evaluated with a case study in the medical field (diabetes diseases).
High Performance Fault Tolerant Resource Scheduling in Computational Grid Environment
Authors: Goswami Sukalyan , Mukherjee Kuntal
Published: October 2019

Virtual resources team up to create a computational grid, which is used in computation-intensive problem solving. A majority of these problems require high performance resources to compute and generate results, making grid computation another type of high performance computing. The optimization in computational grids relates to resource utilization which in turn is achieved by the proper distribution of loads among participating resources. This research takes up an adaptive resource ranking approach, and improves the effectiveness of NDFS algorithm by scheduling jobs in those ranked resources, thereby increasing the number of job deadlines met and service quality agreements met. Moreover, resource failure is taken care of by introducing a partial backup approach. The benchmark codes of Fast Fourier Transform and Matrix Multiplication are executed in a real test bed of a computational grid, set up by Globus Toolkit 5.2 for the justification of propositions made in this article.

“Medicina e Morale” e l’aborto Rassegna di 60 anni di attenzione al problema e di impegno educativo per il superamento della interruzione volontaria di gravidanza
Authors: Bompiani Adriano
Published: October 2019

L’Autore esamina i contenuti di un insieme di oltre 150 articoli pubblicati sulla rivista “Medicina e Morale” dalla fondazione ad oggi (60 anni di esercizio editoriale), a vario titolo diretti alla approfondita conoscenza del fenomeno dell’aborto volontario, con particolare riguardo alla introduzione in Italia della disciplina di legalizzazione. In una prima sezione della raccolta, sono descritte le condizioni culturali che ne hanno sostenuto la regolamentazione e – successivamente – viene esaminato il dibattito che ha accompagnato e seguito la proclamazione della legge 194/1978. Nella seconda sezione della raccolta, l’esame viene esteso non solamente ai contributi pubblicati sulla Rivista riguardanti aspetti particolari contemplati dalla legge, ma vengono esaminati anche contributi che si muovono nello stesso contesto di valutazioni morali (come ad es., la questione dello statuto dell’embrione, della selezione genetica, della “riduzione fetale”, dell’aborto medicamentoso, della contraccezione d’emergenza, ecc.). L’insieme dei contenuti dimostra una alta omogeneità nelle valutazioni ed un comune impegno – costante nel tempo – dei diversi Autori a fornire al lettore non solamente una scientifica oggettiva informazione dei fatti, ma anche ad operare con un costante sforza riflessivo per il superamento della interruzione volontaria di gravidanza. ---------- The Author examines the contents of a set of over 150 articles published in the “Medicine and Morals” journal from the foundation to date (60 years of editorial work), in different ways aimed at the in-depth knowledge of the phenomenon of abortion, particularly with regard to the introduction of the discipline of legalization in Italy. In the first part of the collection, the cultural conditions that have supported the regulation are described and – later – the debate around the laws 194/1978 is examined. In the second part of the collection, examination is extended not only to papers published in the journal on particular aspects of the law, but also to contributions that move within the same context of moral judgments. All content shows a high uniformity of the assessments and a common commitment of the different authors – consistent over time – to provide the reader not only for an objective scientific information of the facts, but also for work with a strong reflection to overcome abortion.
Modelli deliberativi per l’allocazione delle risorse in sanità: il caso della dengue in Tanzania
Authors: Mancini Elena , Zagarella Roberta Martina
Published: October 2019

Nei piani di intervento a sostegno dei sistemi sanitari dei paesi in via di sviluppo, l’utilizzo prevalente di approcci tecnici (basati su strumenti economici) ha rappresentato la via maestra per l’individuazione delle priorità sanitarie. Tali approcci mostrano tuttavia il limite, sotto il profilo etico, di non includere un’analisi dei valori e del contesto culturale e di essere scarsamente responsivi nei confronti delle reali domande di salute della popolazione. Nascondono, inoltre, un sostanziale conflitto tra i valori sottesi, quali l’efficienza e l’equità. La nostra analisi si rivolge ai modelli partecipati e deliberativi di allocazione delle risorse, e specialmente all’approccio elaborato da Norman Daniels – che prende il nome di Accountability for Reasonableness (A4R) – con l’intento di proporre un metodo finalizzato alla definizione di priorità “giuste”, definite cioè non in base a predefinite scelte di valori bensì derivanti da una procedura deliberativa legittima (trasparente e negoziata tra tutti i portatori di interessi in gioco). Per testare l’applicabilità in circostanze reali (soprattutto per paesi a basso reddito) del modello A4R, l’articolo propone l’analisi dello studio di un caso. In particolare, viene esaminata una concreta applicazione dell’A4R relativa alla prioritarizzazione degli interventi di contrasto alla Dengue in Tanzania, al fine di mostrare cosa ha funzionato in questa circostanza specifica, quali difficoltà si sono incontrate e quali reazioni sono scaturite da parte della popolazione.

Comparison of Efficacy of Conventional Nonmodified-Release Minocycline and Newer Extended-Release Minocycline in Treatment of Acne Vulgaris
Authors: Sardesai Vidyadhar R , Uttamani Ruhi R
Published: October 2019

Aims:

The aim is to study the efficacy of conventional and extended-release minocycline therapy in acne vulgaris and to compare the two regimens for the efficacy and side effects.

Materials and Methods:

An open, randomized, comparative, prospective study was conducted on forty newly diagnosed cases of acne vulgaris (Grades 2 and 3) with more than 15 lesions. Patients were randomly allotted into one of the two groups which received extended-release minocycline and conventional minocycline, respectively, for 3 weeks. Both groups were prescribed local application of benzoyl peroxide 2.5% at night. All the patients were evaluated at the end of 3 weeks using paired and unpaired t-test.

Results:

Improvement was noted in patients belonging to both the groups. When both the groups were compared statistically using unpaired t-test, extended-release minocycline was significantly better in the treatment of inflammatory papules.

Conclusions:

Both conventional minocycline and extended-release minocycline were effective in the treatment of moderate and moderately severe acne vulgaris. Statistically inflammatory lesions respond better to extended-release minocycline.

In this note we give a new proof of the sharp constant

C = e^{-1/2} + \int_0^1 e^{-x^2/2}\,dx

in the weak (1, 1) inequality for the dyadic square function. The proof makes use of two Bellman functions

\mathbb{L}

and

\mathbb{M}

related to the problem, and relies on certain relationships between

\mathbb{L}

and

\mathbb{M}

, as well as the boundary values of these functions, which we find explicitly. Moreover, these Bellman functions exhibit an interesting behavior: the boundary solution for

\mathbb{M}

yields the optimal obstacle condition for

\mathbb{L}

, and vice versa.
Integration of Continuous Quality Improvement Methods Into Annual Program and Institutional Evaluation
Authors: Stansfield R. Brent , Markova Tsveti , Baker Richard
Published: October 2019

Background

The Accreditation Council for Graduate Medical Education's Next Accreditation System requires continuous program improvement as part of program evaluation for residency training institutions and programs.

Objective

To improve the institutional- and program-level evaluation processes, to operationalize a culture of continuous quality improvement (CQI), and to increase the quality and achievement of action items, the Wayne State University Office of Graduate Medical Education (WSU GME) incorporated CQI elements into its program evaluation process.

Methods

Across 4 academic years, WSU GME phased the following 4 CQI elements into the evaluation process at the program and institutional levels, including the annual program evaluation (APE) and the annual institutional review: (1) An APE template; (2) SMART (specific, measurable, accountable, realistic, timely) format for program and institutional goals; (3) Dashboard program and institutional metrics; and (4) Plan-do-study-act cycles for each action item.

Results

Action item goals improved in adherence to the SMART format. In 2014, 38% (18 of 48) omitted at least 1 field, compared with 0% omitting any fields in 2018. More complete action items took less time to resolve: 1.7 years compared with 2.4 years (t(43.3) = 2.87, P = .003). The implementation of CQI in the APE was well received by program leadership.

Conclusions

After leveraging CQI methods, both descriptions of institutional- and program-level goals and the time required for their achievement improved, with overall program director and program coordinator satisfaction.
High-resolution (0.05°  ×  0.05°) NOx emissions in the Yangtze River Delta inferred from OMI

Published: October 2019

Abstract. Emission datasets of nitrogen oxides (NOx) at high horizontal resolutions (e.g., 0.05∘×0.05∘) are crucial for understanding human influences at fine scales, air quality studies, and pollution control. Yet high-resolution emission data are often missing or contain large uncertainties especially for the developing regions. Taking advantage of long-term satellite measurements of nitrogen dioxide (NO2), here we develop a computationally efficient method of estimating NOx emissions in major urban areas at the 0.05∘×0.05∘ resolution. The top-down inversion method accounts for the nonlinear effects of horizontal transport, chemical loss, and deposition. We construct a two-dimensional Peking University High-resolution Lifetime-Emission-Transport model (PHLET), its adjoint model (PHLET-A), and a satellite conversion matrix approach to relate emissions, lifetimes, simulated NO2, and satellite NO2 data. The inversion method is applied to the summer months of 2012–2015 in the Yangtze River Delta (YRD; 29–34∘ N, 118–123∘ E) area, a major polluted region of China, using the NO2 vertical column density data from the Peking University Ozone Monitoring Instrument NO2 product (POMINO). A systematic analysis of inversion errors is performed, including using an independent test based on GEOS-Chem simulations. Across the YRD area, the summer average emissions obtained in this work range from 0 to 15.3 kg km−2 h−1, and the lifetimes (due to chemical loss and deposition) range from 0.6 to 3.3 h. Our emission dataset reveals fine-scale spatial information related to nighttime light, population density, road network, maritime shipping, and land use (from a Google Earth photo). We further compare our emissions with multiple inventories. Many of the fine-scale emission structures are not well represented or not included in the widely used Multi-scale Emissions Inventory of China (MEIC).

Abstract. The southeast Atlantic is home to well-defined smoke outflow from Africa coinciding vertically with extensive marine boundary-layer cloud decks, both reaching their climatological maxima in spatial extent around September. A framework is put forth for evaluating the performance of a range of global and regional aerosol models against observations made during the NASA ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS) airborne mission in September 2016. The sparse airborne observations are first aggregated into 2° grid boxes and into three vertical layers: the cloud-topped marine boundary layer (MBL), the layer from cloud top to 3 km, and the 3–6 km layer. Aerosol extensive properties simulated for the entire study region for all September suggest that the 2016 ORACLES observations are reasonably representative of the regional monthly average, with systematic deviations of 30 % or less. All six models typically place the bottom of the smoke layer at lower altitudes than do the airborne lidar observations by 300–1400 m, whereas model aerosol top heights are within 0–500 m of the observations. All but one of the models that report carbonaceous aerosol masses underestimate the ratio of particulate extinction to the masses, a proxy for mass extinction efficiency, in 3–6 km. Notable findings on individual models include that WRF-CAM5 predicts the mass of black carbon and organic aerosols with minor (~ 10 % or less) biases. GEOS-5 overestimates the carbonaceous particle masses in the MBL by a factor of 3–6. Extinction coefficients in the free troposphere (FT) and above-cloud aerosol optical depth (ACAOD) are 10–30 % lower in WRF-CAM5, 30–50 % lower in GEOS-5, 10–40 % higher in GEOS-Chem, 10–20 % higher in EAM-E3SM except for the practically unbiased 3–6 km extinction, and 20–70 % lower in the Unified Model, than the airborne in situ, lidar and sunphotometer measurements. ALADIN-Climate also underestimates the ACAOD, by 30 %. GEOS-5 and GEOS-Chem predict carbon monoxide in the MBL with small (10 % or less) negative biases, despite their overestimates of carbonaceous aerosol masses. Overall, this study highlights a new approach to utilizing airborne aerosol measurements for model diagnosis.
A statistical-parametric model of tropical cyclones for hazard assessment
Authors: Arthur William C.
Published: October 2019

Abstract. We present the formulation of an open-source, statistical-parametric model of tropical cyclones (TCs) for use in hazard and risk assessment applications. The model derives statistical relations for TC behaviour (genesis rate and location, intensity, speed and direction of translation) from best-track datasets, then uses these relations to create a synthetic catalogue based on stochastic sampling, representing many thousands of years of activity. A parametric wind field, based on radial profiles and boundary layer models, is applied to each event in the catalogue that is then used to fit extreme value distributions for evaluation of return period wind speeds. We demonstrate the capability of the model to replicate observed behaviour of TCs, including coastal landfall rates which is of significant importance for risk assessments.

Semarang - Solo Toll Road is part of the Trans Java highway, which has a strategic meaning in the development of road networks, specifically in Central Java and also on a regional scale. The construction project generally consists of excavation work, stockpiles and bridge work. The number of work in the project therefore allows the emergence of a problem that can hinder the development process and one of which was related to concrete casting in the construction of the Kali Putih Bridge 1, where there was a slump decrease in columns P1 and P3 concrete pre-casting (30 Mpa). However, a slump test was carried out on column P1 in STA. 61 + 368,500, and P3 in STA. 61 + 293,500, which resulted in 3.5 cm and 4 cm collapse respectively. Hence, they did not meet specification on B-1 concrete, which was 7.5 ± 2.5 cm. In addition, Superplasticizer was used to overcome this problem, as it was capable of restoring freshness/workability. This study, therefore, aimed to determine the effect of the incorporating superplasticizer and retarder into concrete, on its compressive strength, slump decrease, and time, utilizing 24 test cylindrical specimens (7-days and 14-days), through pressure testing. Furthermore, the slump testing was conducted every 20 minutes for 120 minutes, to determine the reduction time, and the findings further indicated that adding a retarder to class B-1 concrete was capable of increasing the functional period (67 minutes on a slump of 7 ± 2.5 cm). However, the addition of Superplasticizer was also able to repair the slumps, which did not meet the requirements, including the specimen that involved the incorporation of a retarder (82.5 minutes, which resulted in a 1.9 cm slump that was further increased to 17.5 cm after augmentation. Furthermore, these effects were due to its ability to reduce the compressive strength by 3.13% and 6.14% on the 7-days and 14-day specimens, respectively. However, the SPSS v.23.0 test results showed the difference in compressive strength between the normal concrete + retarder and normal concrete + retarder + SP, with a sig value of 0.021 <a = 0.05 (Turkey HSD Test) and 0.0009 <a 0.05 (LSD Test).
Are You Now or Have You Ever Been a Suvinian? Beyond the Moralizing Temptation; or, How Not to Read
Authors: Wegner Phillip E.
Published: October 2019

This article begins as a response to a review recently published in Utopian Studies. It argues that the prescriptive forms of ethical criticism practiced in this review are symptomatic of more general trends in our scholarly communities. The article is modeled on Jacques Derrida's “Limited Inc a b c. …” In his essay, Derrida illustrates the ways that genres such as the review, reply, and response open up the temptation to not read and to slip into moralizing modes of ethical judgment. Following Derrida's lead, the response unfolds at once in terms of what J. L. Austin identifies as a constative and a performative utterance: In its contents, it addresses misrepresentations and unspoken “absolute presuppositions”; and in its form, it enacts some of the practices that would be necessary for a more productive, responsible, and generous—that is, utopian—way of performing our intellectual labors.

¿Qué pasaría sin la unidad para la pervivencia como pueblo?: Identidad indígena en tierraadentro, Cauca, Colombia
Authors: Perdomo Pancho Ana Edy , García Figueroa Vianney Judith
Published: October 2019

La presente investigación arroja fundamentaciones conceptuales, teóricas y orales, desde la memoria política de los Mayores que han aportado al proceso político organizativo a nivel local, zonal y regional en las recuperaciones de tierras en la vereda Quiguanás, en el municipio de Inzá – Cauca, como estrategia de lucha y de resistencia para seguir caminando la palabra en el Consejo Regional Indígena del Cauca – CRIC. Los resultados obtenidos parten de las historias de vida, de cada uno de los Mayores que hacen parte de la memoria de la comunidad y que están siendo olvidados en tiempos modernos, por lo que es necesario empezar un proceso de sensibilización en los jóvenes de la comunidad para que valoren su saber político y espiritual para vivir bien y en armonía con nuestra Madre Tierra. Por lo tanto, la base del movimiento indígena es la unidad en la diversidad de pensamientos para la reivindicación de derechos colectivos desde la resistencia y recuperación de la Madre Tierra como eje fundamental del ser indígena para pervivir en el tiempo y en el espacio como ser Nasa, pensamiento que se ha legado a las próximas generaciones.
Análisis del razonamiento verbal y su incidencia en la formación periodística intercultural, en el club de periodismo de la unidad educativa Víctor Manuel Peñaherrera, cantón Ibarra provincia de Imbabura-Ecuador

Esta investigación analiza el tema del razonamiento verbal y su incidencia en la formación periodística intercultural, concretamente sobre la enseñanza de la escritura periodística. Es un estudio cualitativo con una perspectiva decolonial motivado por los actuales aportes de la comunicación intercultural, comunicación propia y periodismo indígena. Se propuso conocer y desentrañar los factores colonizantes que dominan la enseñanza de la escritura periodística en lengua española y que homogenizan la escritura. En esta investigación participaron estudiantes del club de periodismo de la Unidad Educativa Víctor Manuel Peñaherrera. La información se recogió a partir de un proceso vivencial de trabajo focal con jóvenes de bachillerato con aptitud por el periodismo. El análisis consistió en observar la aplicación de la normativa de razonamiento verbal en prácticas concretas de escritura periodística en contraste con las teorías de la comunicación intercultural. Los resultados muestran que el campo de razonamiento verbal es un preconcepto funcional que arrastra herencias coloniales y norma en su totalidad el sistema de comunicación escrita. Los objetivos y contenidos se alejan del verdadero sentido de la comunicación, limita la libertar intercultural de escribir, expresar y comunicar, anulan la diversidad de razonamientos y realidades pluriverbales así como incide en la compresión y practica de los géneros periodísticos, a tal modo que el periodismo convencional es visto como “la profesión de escribir bien”, es decir; restrictivo, por lo que no despierta interés. Por lo tanto, se hace necesario interculturalizar el proceso de enseñanza de la escritura periodística y abrirle campo al periodismo intercultural.
A Call for Social Work Intervention to Address the Phenomenon of Child Sexual Abuse against Learners in South African Schools: A Review of the Literature
Authors: Masilo Daniel Tuelo
Published: October 2019

Child sexual abuse (CSA) is undoubtedly one of the social problems negatively affecting children in South Africa. Everyday reports in research and different media platforms such as radio, television, social media and newspapers suggest that sexual abuse of children and those attending school, has reached unprecedented proportions. Within the school setting, it is reported that school-based employees such as teachers, security personel and gardeners are alleged to be the perpetrators of this heinous crime against children. The purpose of this paper through the literature review methodology, is to highlight the phenomenon of CSA perpetrated against learners in the South African schools and indicate how the social work profession may intervene. To this end, this paper calls social workers to intervene by means of educating learners on child sexual abuse, establishing and strengthening the childcare and protection forums, engaging parents, guardians and lastly facilitating dialogues with the school-based employees. These interventions will go a long way in addressing the phenomenon of CSA, and most importantly, protecting the rights of children as the most vulnerable group in societies.
