Translating Flowering Time from Arabidopsis thaliana to Brassicaceae and Asteraceae Crop Species
Authors: Leijten Willeke , Koes Ronald , Roobeek Ilja , Frugis Giovanna
Published: December 2018

Flowering and seed set are essential for plant species to survive, hence plants need to adapt to highly variable environments to flower in the most favorable conditions. Endogenous cues such as plant age and hormones coordinate with the environmental cues like temperature and day length to determine optimal time for the transition from vegetative to reproductive growth. In a breeding context, controlling flowering time would help to speed up the production of new hybrids and produce high yield throughout the year. The flowering time genetic network is extensively studied in the plant model species Arabidopsis thaliana, however this knowledge is still limited in most crops. This article reviews evidence of conservation and divergence of flowering time regulation in A. thaliana with its related crop species in the Brassicaceae and with more distant vegetable crops within the Asteraceae family. Despite the overall conservation of most flowering time pathways in these families, many genes controlling this trait remain elusive, and the function of most Arabidopsis homologs in these crops are yet to be determined. However, the knowledge gathered so far in both model and crop species can be already exploited in vegetable crop breeding for flowering time control.
Recycling Potential for Finely Divided Ferrous Metallic Scrap Using Powder Technology
Authors: Rane Kedarnath , Date Prashant P.
Published: December 2018

Enormous amount of scrap is generated on the shopfloor during manufacturing. Energy needed to melt increasing quantities of scrap will be ever increasing, and so will be the loss of metal during melting. Hence, conversion of scrap directly into marketable products by solid state processing methods is economical due to a lower energy requirement and a greater yield compared to the melting route. This makes the process more environmentally friendly. However, not all materials can be recycled in a solid state, with equal ease. One therefore needs to quantitatively assess the recyclability of a given kind of scrap. In the present work, a procedure to assess the recyclability of finely divided ferrous metallic scrap generated on the shopfloor is demonstrated. Recyclability includes material and the process used for recycling. For instance, a given material might be more recyclable using one process compared to the other. In the present study, the potential of powder technology (powder metallurgy (PM) and metal injection molding (MIM) based processes are compared for solid-state conversion of scrap directly into usable products. Grinding sludge collected in the shopfloor was pulverized and used as raw material. Properties of sintered parts were found to be significantly better due to in-situ reduction and densification during sintering. A quantitative measure of recyclability, namely, the Recyclability Index (RI) was defined to compare the manufacturability of different products. Recycled ferrous parts manufactured by PM route are found to have a greater RI (superior recyclability) than those manufactured by the MIM route. Complex reduction and sintering mechanisms in MIM parts, particularly, the kinetics of diffusion and volumetric shrinkage, limit suitability of MIM for recycling. In contrast, few industrial parts were developed and manufactured by conventional PM based approach to demonstrate the suitability of this novel recycling process especially for manufacture of porous parts.
A Relationship of Causal Factors in the Economic, Social, and Environmental Aspects Affecting the Implementation of Sustainability Policy in Thailand: Enriching the Path Analysis Based on a GMM Model
Authors: Sutthichaimethee Pruethsan , Dockthaisong Boonton
Published: December 2018

This research aimed to analyze the influence of the direct and indirect relationships of economic, social, and environmental factors as well as predict their future effects by applying a path analysis of a generalized method of moments model (path analysis–GMM model). The model is believed to be the most effective in relationship analysis, as it is capable of accurate prediction compared to the original models. Most importantly, the model can be applied to different contexts, benefiting the development areas of those contexts. Furthermore, the model has also been found to be the best linear unbiased estimation (BLUE), which is suitable for long-term forecasting. However, the study’s results reflect that the three latent variables of economic, social, and environmental factors have direct and indirect effects. In addition, both economic and social factors were found to have causal relationships. The availability of the path analysis–GMM model enables us to forecast the social and economic changes over the next 20 years (2019–2038), and predict the change in energy-related CO2 emissions for the next 20 years (2019–2038). Thus, the study was able to discern the economic and social growth of Thailand. Studies have shown that the economic and social growth of Thailand has increased by 7.85%, based on various indicators. The economic indicators include per capita gross domestic product ( G D P ) , urbanization rate ( U R E ) , industrial structure ( I S E ) , net exports ( X − E ) , and indirect foreign investment ( I F I ) , while the social indicators include employment ( E M S ) , health and illness ( H I S ) , social security ( SSS ) , and consumer protection ( CPS ) . However, the environment has continuously deteriorated, as understood via environmental indicators such as energy consumption ( E C E ) , energy intensity ( E I E ) , and carbon dioxide emissions ( C O 2 ) . This is due to the increment of CO2 emissions in energy consumption of 39.37% (2038/2019) or 103.37 Mt CO2 eq. by 2038. However, by using the path analysis–GMM model to test for performance, it produced the mean absolute percentage error (MAPE) of 1.01% and a root mean square error (RMSE) of 1.25%. A comparison of the above results with other models, including the multiple regression model, grey model, artificial neural natural model (ANN model), back propagation neural network (BP model), and the autoregressive integrated moving average model (ARIMA model) provided evidence that the path analysis–GMM model was the most suitable in forecasting and contextual application to support the formulation of the national strategy in the future.

Authors: Huang Cairui , Shen Congcong , Jin Ling , Cai Hongwei
Published: December 2018

For monitoring of trace amounts of hydrofluoric acid in the organic fluorine chemical industry, a facile method for determination of the hydrofluoric acid in an ethanol solution of lithium chloride, by coulometric titration, was proposed. Relying on homemade acid–base coulometric autotitrator, the electrolyte was 0.50 mol·L−1 LiCl ethanol solution and the constant current intensity was 0.2–2 mA. As for the working electrode pair, a platinum plate was used as a working electrode, and a platinum wire was used as an auxiliary electrode. The indicating electrode was the pH composite glass electrode and the titration endpoint was pH 5.50. The results showed that the relative standard deviation was below 2.0%, as the content of the hydrofluoric acid was between 2 μg to 100 μg. The recovery rate was 99.0–102.0%. This proposed route has the advantages of simplicity, convenience, quickness, accuracy, and automation, which can be applied to the accurate determination of trace amounts of hydrofluoric acid, in non-aqueous solutions.
A Novel Step Length Estimator Based on Foot-Mounted MEMS Sensors
Authors: Zhu Zhuangsheng , Wang Shibo
Published: December 2018

Pedestrian Dead Reckoning (PDR)-based pedestrian navigation technology is an important part of indoor and outdoor seamless positioning services. To improve the performance of PDR, we have conducted research on a step length estimator. Firstly, based on the basic theory of inertial navigation, we analyze in detail the errors in traditional Strapdown Inertial Navigation Systems (SINSs) caused by the unique motion state of pedestrians. Then, according to the fact that the inertial data from the foot can directly reflect the gait characteristics, we conduct a step length estimator that does not rely on SINS. The experimental results show that accuracy of the proposed method is between 0.6% and 1.4% with a standard deviation of 0.25%.
Existence and Resistance: The Social Model of Community Education in Ireland
Authors: O’Grady Maeve
Published: December 2018

Community education in the Republic of Ireland exists in several forms and in several sites. This article draws on two qualitative research projects in community education to identify the practices of the social model of community education that link them. The context of the research is the impact of policy changes as experienced by the practitioners and providers. The social model can be spoken of in different terms, depending on the practice of the speaker; it can be a process model of curriculum, critical literacy, or feminist emancipatory pedagogy. The article describes different discourses of practice and considers how practitioners could, while differentiating aspects of their practice, find common ground and resist the erosion of adult education for social justice by the state’s drive for vocational education for the labour market.

Moving Urban Sculptures towards Sustainability: The Urban Sculpture Planning System in China
Authors: Liu Zhe , Uyttenhove Pieter , Zheng Xin
Published: December 2018

Following the continuous development characterized by large-scale constructions, Chinese urban development has shifted to the promotion of refined urban space quality. Urban sculpture, an important part of public arts, has been receiving increased attention in China as an important carrier for highlighting urban characteristics, culture, and history within cultural policies. As a type of cultural capital, it offers innovative methods to address the issues of economic, social, and environmental sustainability, in particular cultural sustainability. Interdisciplinary theories of urban planning are creatively applied to guide, coordinate, and improve the sustainable production of urban sculptures in China. This research was initiated to: (1) Illustrate how urban sculptures are produced through an urban planning system in the context of China; (2) explain what kind of influencing factors in relation to sustainability exist, mainly within the framework of planning strategies and cultural policies; and (3) put forward sustainable planning strategies to produce urban sculptures. To answer the above inquiries, we reviewed more than 100 articles, plans, and government documents, and we conducted several semi-structured interviews. The article argues that urban planning strategies and policies have been conceived as strategic instruments by the Chinese municipal governments to realize sustainable development of urban sculptures. Our findings would enrich knowledge on geographic studies of public art planning through the contextualized analysis of a Chinese urban sculpture planning system. It also fills the gap in the literature on the sustainability of urban sculptures by approaching the perspectives of planning strategies and cultural policies.
Does the IFRS Effect Continue? An International Comparison
Authors: Hwang In Tae , Hur Kang Sung , Kang Sun Min
Published: December 2018

Previous research showed that in the early years after adoption, the change to International Financial Reporting Standards (IFRS) impacted accounting quality. The purpose of this study is to analyze whether those effects have changed over time in companies within countries that have different legal regimes, enforcement, and degrees of external investor protection. We measure accounting quality using discretionary accruals, real activities manipulation, and the stock price value relevance of earnings per share and book value per share. The findings show that the early effects of IFRS adoption continue with the passage of time in companies listed in countries with common law systems, such as the United Kingdom (UK) and Australia, which provide powerful outside investor protection in capital markets. Yet, the early effects of IFRS adoption do not continue after the passage of time in companies listed in Asian countries with statutory law systems, such as Korea and China, which have low levels of outside investor protection. Moreover, it is difficult to obtain evidence that value relevance has improved after the accounting measurement of corporate value shifted to IFRS. The results show that there are differences in the sustained effects on accounting quality, even after the application of IFRS due to the different social, economic, and cultural characteristics of countries.

Published: December 2018

The aim of this study is to evaluate the influence of bibliotherapy education on the social-emotional skills of psychological counselling and guidance candidates. The test group of the study consisted of psychological counselling and guidance students who participated voluntarily in the course named “Applied Counselling and Bibliotherapy”. A pre-test and post-test experimental design without a control group was used in the study. The Social Skills Inventory was used, for determining the social skills level of students before and after they are provided with bibliotherapy education. It was concluded from the study that there is a significant difference in the general scores for the social skills of female students after bibliotherapy education and the scores they obtained in the sub-dimensions of social expressivity. With the given reading materials and method of delivery, when the effect of bibliotherapy education on social skills level was compared, it was found in the final test that female students’ scores in the sub-dimensions of emotional expressivity and social control were significantly higher than those of male students. However, it was concluded that male students’ scores in the sub-dimension of emotional control were higher than those of female students.
Urban Physical Environments and the Duration of High Air Temperature: Focusing on Solar Radiation Trapping Effects
Authors: Choi Yeri , Lee Sugie , Moon Hyunbin
Published: December 2018

Urban heat island effects, which are the phenomenon wherein higher ambient air temperatures are measured in cities than in rural areas, have worsened urban thermal environments over the past decades. This study aims to analyze the effects of urban physical environments on the duration of high air temperature, using climate data collected from 217 Automatic Weather Stations in Seoul, Korea. In order to specify radiation trapping effects, interaction effects between sky view factors (SVF) and albedo values were analyzed using multiple regression analysis. The results indicate that increases in commercial and traffic areas lead to longer durations of high air temperature and that high urban porosity shortens the duration of high air temperature by improving urban ventilation. This study also indicates that the duration of high air temperature has a negative association with SVF; however, an analysis of interaction effects indicates that high-albedo materials diminish the positive effects of high SVF largely because of radiation trapping effects. These findings suggest that urban ventilation paths, high SVF, and materials with an appropriate albedo value play important roles in improving thermal comfort conditions, such as the duration of high air temperature.

Published: December 2018

Adequately exploring the tradespace in the early system design phase is important to determine the best design concepts to pursue in the next life cycle stage. Tradespace exploration (TSE) often uses trade-off analysis. Set-based design (SBD) methods, compared to traditional point-based design, explore significantly more designs. An integrated framework with model-based system engineering (MBSE) and a life cycle cost model enables design evaluation in near real-time. This study proposes an early design phase SBD methodology and demonstrates how SBD enabled by an integrated framework with MBSE and life cycle cost provides an enhanced TSE that can inform system design requirements and help decision makers select high performing designs at an affordable cost. Specifically, this paper (1) provides an overview of TSE and SBD, (2) describes the Integrated Trade-off Analysis Framework, (3) describes a methodology to implement SBD in the early design phase, and (4) demonstrates the techniques using an unmanned aerial vehicle case study. We found that the Integrated Trade-off Analysis Framework informs requirement development based upon how the requirements affect the feasible tradespace. Additionally, the integrated framework that uses SBD better explores the design space compared to traditional methods by finding a larger set of feasible designs early in the design process.

Published: December 2018

Schistosoma infection in snails can be monitored by microscopy or indirectly by sentinel mice. As both these approaches can miss infections, more sensitive tests are needed, particularly in low-level transmission settings. In this study, loop-mediated isothermal amplification (LAMP) technique, designed to detect a specific 28S ribosomal Schistosoma japonicum (Sj28S) gene with high sensitivity, was compared to microscopy using snail samples from 51 areas endemic for schistosomiasis in five Chinese provinces. In addition, the results were compared with those from polymerase chain reaction (PCR) by adding DNA sequencing as a reference. The testing of pooled snail samples with the LAMP assay showed that a dilution factor of 1/50, i.e., one infected snail plus 49 non-infected ones, would still result in a positive reaction after the recommended number of amplification cycles. Testing a total of 232 pooled samples, emanating from 4006 snail specimens, showed a rate of infection of 6.5%, while traditional microscopy found only 0.4% positive samples in the same materials. Parallel PCR analysis confirmed the diagnostic accuracy of the LAMP assay, with DNA sequencing even giving LAMP a slight lead. Microscopy and the LAMP test were carried out at local schistosomiasis-control stations, demonstrating that the potential of the latter assay to serve as a point-of-care (POC) test with results available within 60–90 min, while the more complicated PCR test had to be carried out at the National Institute of Parasitic Diseases (NIPD) in Shanghai, China. In conclusion, LAMP was found to be clearly superior to microscopy and as good as, or better than, PCR. As it can be used under field conditions and requires less time than other techniques, LAMP testing would improve and accelerate schistosomiasis control.

Published: December 2018

Abomasal displacement (AD) to the left is a common disease in high-yielding dairy cows after parturition. In view of the previously reported changes in tissue neuropeptide concentrations in cows with AD, the primary aim of this study was to evaluate the effect of AD and breed on serum neuropeptide concentrations. For this purpose, blood samples of 33 German Holstein (GH) cows with AD, 36 healthy controls (GH), and 32 healthy German Fleckvieh (GF) cows were collected, and concentrations of substance P (SP), vasoactive intestinal polypeptide (VIP), and interleukin1β (IL-1β) were measured via commercially available ELISA kits. To examine the effect of AD, we compared GH cows with and without AD and observed no significant effects of AD on SP, VIP, or Il-1 β concentrations. To evaluate the effect of breed, we compared healthy GH with healthy GF cows and detected markedly higher VIP serum levels in the healthy GF cows (p < 0.01). No significant differences in SP or IL-1β were detected. According to our results, there seems to be no effect of AD on the serum concentrations of SP, VIP, or IL-1 β. In contrast, there seems to be a breed difference concerning serum VIP concentrations.

Published: December 2018

Background

Depression is a common mental illness worldwide. The offspring of a mother with depression has higher risk of developing mental and physical illness.

Aim

This study aimed to investigate the association between the timing of maternal depression and the use of primary health care for the offspring.

Design and setting

A population-based birth cohort study in Danish primary care using Danish national registers.

Method

All Danish children born between 1 January 2000 and 31 December 2013 (n = 869 140 children) were included in the study. The primary outcome was number and type of annual contacts with the GP. The secondary outcome was specific services used by the GP to assess inflammatory and infectious disease in the children. Exposure was maternal depression of four categories: non-depressed, recent, previous, and past depression. The association was expressed as adjusted incidence rate ratios (IRR) with 95% confidence intervals (CI).

Results

Maternal depression was associated with a higher use of primary health care for all three categories of depression. The strongest association was found for children of a mother with recent depression; they had 16% more contacts than children of a non-depressed mother (adjusted IRR = 1.16, 95% CI = 1.15 to 1.17), and 19–24% more positive infectious-related tests were found in this group.

Conclusion

Exposure to maternal depression was associated with a significantly higher use of primary health care for the offspring for all exposure categories. These findings reveal that healthcare use is higher for the offspring exposed to maternal depression, even several years after expected remission. The higher ratio of positive tests indicates that exposed children are ill with infectious disease more often.
To Value or Not to Value the Arctic Winter Games?
Authors: Mahadevan Renuka , Ren Carina
Published: December 2018

This article examines the question of how to engage with the value generated by large sport events by reviewing valuation studies on sports events and explaining the need to differentiate the valuing of events in the short and long run. It is argued that the latter, measured by the
notion of public value, is a relevant concept to consider in addition to social valuation defined here as a short-run concept. The Arctic Winter Games, a youth sports event, was used to shed light on these valuation concepts by showcasing how the event spurred a large range of outcomes. Based
on fieldwork in the preparation phases of the event to identify relevant outcomes and using the contingent valuation method, it was found that the social value of the Games (although it was free to attend), estimated at US$10.5 million in the short run, outweighed the cost of US$9.4
million. Some suggestions for measuring the public value of sports events and a dynamic approach of sequentially refining the process of exploring and measuring long-lasting effects as they vanish or unfold is proposed.
SOVIET HERITAGE AS ETHICAL IMPERATIVE FOR CONTEMPORARY LITHUANIAN ARCHITECTURE
Authors: Petrulis Vaidas
Published: December 2018

The paper analyses ethical imperatives for the soviet time heritage in contemporary Lithuanian architecture. The main statement of this paper is that the soviet period is an important part in the 20th century history of Lithuanian architecture. However, because of economic, cultural and ideological changes after the collapse of the Soviet Union this unprotected by law architectural heritage gradually disappears. The paper discusses the idea that only ethical consideration of contemporary society towards this problem can change the situation. Also, it is pointed out that the ethical responsibility lies not only on architects and construction developers but also on the entire society, which supports the idea to have this architecture as a part of our city in order to reflect its cultural and architectural history. The position regarding this part of heritage should be much more creative compared with traditional attitude towards architectural heritage.

Sovietmečio palikimas kaip etinis imperatyvas šiuolaikinei Lietuvos architektūrai

Nagrinėjami sovietmečio paveldo imperatyvai šiuolaikinei Lietuvos architektūrai. Konstatuojama, kad svarbi Lietuvos XX a. architektūros paveldo dalis, žlugus Sovietų Sąjungai, dėl įvairių ekonominių, kultūrinių ir ideologinių priežasčių praranda savo patrauklumą ir, nesaugoma įstatymų, gan greitai nyksta. Diskutuojama idėja, kad tik aktyvi šiuolaikinės visuomenės pozicija gali šią situaciją pakeisti. Tačiau XX a. architektūra nėra įprastas paveldo objektas, todėl požiūris į šį paveldą turi būti kūrybingesnis, aktyviau prisitaikant prie šiuolaikinio miesto poreikių. Pabrėžta, kad etiniai imperatyvai čia svarbūs ne tik tradiciškai architektams bei statybų vystytojams, bet ir už architektūros paveldą atsakingiems visuomenės atstovams.

. In such systems there is a scale l
0 at which the spectrum has to break due to the condition of weak compressibility. A very good example of this dynamics is offered by solar wind fluctuations in Alfvénic fast streams, characterized by the property of constant field magnitude. We show here that the distribution of

Based on the second Gaia data release and spectroscopy from the Large Sky Area Multi-object Fiber Spectroscopic Telescope (LAMOST) Data Release 5, we define the high-velocity (HiVel) stars sample as those stars with v
gc > 0.85v
esc, and derived the final sample of 24 HiVel stars with stellar astrometric parameters and radial velocities. Most of the HiVel stars are metal poor and α-enhanced. In order to further explore the origin of these HiVel stars, we traced the backward orbits of each HiVel star in the Galactic potential to derive probability parameters that are used to classify these HiVel stars. Of these, 5 stars are from the tidal debris of disrupted dwarf galaxy, and 19 stars are runaway-star candidates originating from the stellar disk.

Published: December 2018

Comparative biology may reveal novel therapeutic
strategies against human diseases. Ischemia‑reperfusion (IR)
injury induces a number of diseases. It is known that
hibernating mammals survive IR since during hibernation,
prolonged periods of torpor with a marked decrease in blood
flow and breathing rate are interrupted by short periods of
arousal. In the present study, the differences in the character‑
istics of endoplasmic reticulum (ER) stress and the subsequent
unfolded protein response, which are induced by IR and may
cause cell death among humans, mice or the native hibernator
Syrian hamster were examined in vitro using renal proximal
tubular epithelial cells (RPTECs) derived from these three
sources. RPTECs were subjected to anoxia or reoxygenation,
both at 37˚C. Cell death was measured by LDH release assay.
ER stress was assessed by determining the levels of phos‑
phorylated protein kinase RNA‑like ER kinase, ubiquitinated
proteins and Bcl‑2‑associated X protein (Bax) by western blot
analysis. For proteasomal activity, a specific assay was used.
The results revealed that anoxia induced ER stress in all the
evaluated RPTECs, from which only the hamster‑derived
RPTECs recovered during reoxygenation. Anoxia and reoxy‑
genation increased protein ubiquitination in the human‑ and
mouse‑derived RPTECs, whereas this was decreased in the
hamster‑derived RPTECs. Anoxia enhanced proteasomal
activity in all the evaluated RPTECs. In the human‑ and
mouse‑derived RPTECs, reoxygenation reduced proteasomal
activity, which remained high in the hamster‑derived RPTECs.
Anoxia and reoxygenation increased Bax expression and
induced cell death in the human‑ and mouse‑derived RPTECs,
while neither Bax overexpression nor cell death occurred in
the hamster‑derived RPTECs. Thus, on the whole, the find‑
ings of this study demonstrate that compared to human‑ or
mouse‑derived RPTECs, those derived from the hamster
recover more rapidly from ER stress following warm
anoxia‑reoxygenation, possibly due to increased proteasomal
function.

Un enthousiasme paradoxal ? Georges Canguilhem et la biologie moléculaire (1966-1973)
Authors: Loison Laurent
Published: December 2018

Ce travail est consacré à la rencontre entre la philosophie canguilhémienne et la biologie moléculaire. Nous montrons que durant la seconde moitié des années 1960, Canguilhem fut moins gêné par le réductionnisme mécaniste de cette nouvelle biologie qu’il ne fut enthousiasmé par ce qu’elle semblait impliquer sur le plan de la théorie de la connaissance. Prenant au pied de la lettre l’idée alors très en vogue que la vie était langage, il pensa un temps pouvoir identifier le concept et la vie et ainsi réactiver une certaine forme de néo-aristotélisme. Cette perspective paraissait à même d’offrir une solution au problème de la connaissance de la vie, problème qui était au fondement de sa démarche philosophique depuis au moins le début des années 1940. Nous montrons ensuite que Canguilhem changea d’avis dans les textes qu’il publia après 1970. Discrètement, mais incontestablement, il renonça à la portée gnoséologique de la biologie moléculaire pour laquelle il avait nourri tant d’attentes quelques années auparavant. Ce revirement doit beaucoup, selon nous, à la lecture du livre de François Jacob, La Logique du vivant .
Risques psychosociaux : envisager le burnout comme un processus organisationnel
Authors: Picart Ludovic , Jaussaud Jacques
Published: December 2018

Le Burnout, ou épuisement professionnel, est un syndrome souvent étudié dans le champ des sciences humaines. Il est alors défini par un état complet d’épuisement pour les uns, par un processus d’épuisement progressif pour les autres. Nous plaçant du point de vue des sciences de gestion, nous nous efforçons dans cette contribution, par l’étude qualitative approfondie d’un cas réel, d’identifier les facteurs organisationnels déterminants du burnout, puis de mettre en évidence le processus organisationnel conduisant à de telles situations. Les facteurs organisationnels mis en évidence peuvent être cadencés avec les trois dimensions du processus du burnout décrites par Maslach et Jackson (1981), dimensions essentiellement individuelles. A partir de nos résultats, nous proposons une formalisation simple du processus organisationnel du burnout, nous permettant de formuler des préconisations nouvelles en matière de prévention de ce phénomène.
Que faire avec des matériaux incertains ? Le cas d’une sociologie des violences dans le football amateur
Authors: Demazière Didier , Nuytens Williams
Published: December 2018

Fondé sur une série d’enquêtes portant sur les violences commises dans le football amateur, cet article interroge le caractère problématique des matériaux discursifs. En sociologie, l’incertitude de la parole est généralement formulée en termes de rapports entre discours rétrospectifs et réalité passée. Dans le cas traité ici, le caractère inobservable du phénomène étudié renforce cette incertitude, confrontant l’enquêteur à des discours singulièrement fragiles. Plus encore, les discours sur les violences abondent mais s’appuient rarement sur l’expérience directe des enquêtés. Cela nous conduit à caractériser le statut de ces locuteurs et informateurs et à le définir par l’expression paradoxale de témoins potentiels. Puis, nous qualifions le caractère problématique des discours collectés, en distinguant des récits d’expérience, des récits canoniques et des récits identitaires, considérés comme autant de manières de constituer, raconter et argumenter les phénomènes de violence.
Running together to explore the city: How foreigners discover the city through experiences of a sports group

Comment des immigrés, nouvellement arrivés au Luxembourg pour le travail, vont-ils découvrir la ville par la pratique sportive en groupe ? Telle est l’une des questions posées lors de cette recherche ethnographique sur la pratique sportive quotidienne d’un groupe de salariés de deux organismes de recherches employant un pourcentage important d’étrangers. La démarche inductive de la théorisation enracinée a fait émarger de manière concomitante l’enjeu pour ces étrangers de l’intégration dans un nouveau pays et la découverte d’une ville, en tant qu’expérience sensible. Les notions d’interaction et d’intégration, empruntées à l’École de Chicago, ont constitué l’outillage théorique de l’analyse des données recueillies par le biais d’observations, d’entretiens, avec l’utilisation notamment de carte dessinée de son environnement connu. L’enquête montre comment l’expérience de courses à pied en groupe est un média au travers duquel les individus interagissent avec la ville et son histoire, se construisant leur histoire dans la ville.
Tuberculosis Education for Nurse Practitioner Students: Where We Are and Where We Need to Go

Tuberculosis (TB) has reemerged as a public health concern. This study tested the reliability and validity of an instrument examining self-efficacy in providing TB care, beliefs about educational preparation, and knowledge about TB among nurse practitioner students from diverse programs. A one-time self-report instrument was distributed during a final clinical course. Rasch analysis was used to assess the instrument's reliability and validity. Most of the 92 respondents were from family nurse practitioner programs and had received TB education via lecture. Students were moderately knowledgeable on TB content and had a moderate level of perceived self-efficacy. They valued TB education as it related to both their current program and their clinical practice. The instrument had excellent reliability (a = 0.96 to 0.98), and it appears to be an effective measure to help faculty understand student knowledge and confidence in the care of individuals with TB.
Investigation of Combined SVC and TCSC versus IPFC in Enhancing Power System Static Security

Electrical power systems are often required to operate at full loading capacity due to ever increasing demand and transmission line contingencies with limited grid expansion. This results in line overload and operating near system limit, thereby threatening system security. Utilization of existing system can be achieved using Flexible Alternating Current Transmission System (FACTS) devices without violating system limits. This research investigation involves static security assessment of a modelled IEEE 30-bus test system in MATLAB/SIMULINK/PSAT environment. The security status with the incorporation of combined Static Var Compensator (SVC), Thyristor Controlled Series Compensator (TCSC) and Interline Power Flow Controller (IPFC) were determined. Prior to this, Contingency Severity Index (CSI) based on Performance Index (PI) of Voltage and Active Power was employed to determine the optimal location of the FACTS devices. Sequential Quadratic Programming (SQP) was applied to determine the optimal sizing/percentage compensation of FACTS. Subsequently, power system with and without the incorporation of FACTS devices were modelled. The ability of the compensated system to withstand credible transmission line contingencies without violating the normal operating limits (bus voltage and line thermal) was examined and presented. The paper presents how combined SVC/TCSC and an IPFC aided the power system to boost its steady state security in the face of possible line contingencies.
Modelling and Optimization of Integrated Planning of Production and Maintenance with Subcontract Constraint
Authors: Hafidi Nouhayla , El Barkany Abdellah , Mahmoudi Morad
Published: December 2018

This article addresses the problem of the joint policy of production and maintenance under constraint of outsourcing. The production system considered brings together two companies; the principal represented by a machine Md, while the subcontractor represented by a machine Ms. Our production system aims to satisfy a constant and continuous demand for a single product type. Indeed, outsourcing is justified by the lack of production capacity. However, the main objective is to determine simultaneously for each period, the age of preventive maintenance, the optimal stock threshold level, the maximum capacity of subcontractor and its unit cost of production, to better satisfy the customer's need. The last two parameters encourage an optimal choice of subcontractor, while minimizing the total cost generated by the contractor, including the costs of maintenance, production, storage and shortage. The results show that the proposed model performs quite well and opens new research direction for future improvements.

This research assessed the effect of Nigerian rice husk ash (RHA) and calcium chloride (CaCl2) as partial replacement of cement in concrete grade 20. Rice husk ash (RHA) is obtained by combustion of rice husk in a controlled temperature. The replacement of OPC with rice husk ash (RHA) were 0%, 5%, 10%, 15% and 20%. 1% of Calcium Chloride was blended with OPC/RHA in all the test specimens except from control mix. Concrete cubes of sizes 150mm x 150mm x 150mm were cast and cured in water for 7, 14 and 28 days respectively. Slump test was conducted on fresh concrete while density test and compressive strength test were conducted on hardened concrete. The slump results revealed that the concrete becomes less workable (stiff) as percentage increases. The compressive strength result at 28 days revealed that 5%RHA/1%CaCl2 have the highest strength of 26.82N/mm2 while 20%RHA/1%CaCl2 have the lowest strength (21.48N/mm2). Integration of 5%RHA/1%CaCl2 and 10%RHA/1%CaCl2 as cement replacement will produce a concrete of higher compressive strength compared to conventional concrete in grade 20 concrete.

Published: December 2018

The study focused on the model analysis of failure susceptibility for some roads in the South-western part of Nigeria using TDRAMS model along with its modified version. TDRAMS, a model prepared through an analyzed weight-rating system was used to analyze pavement failure manifestation in the present study area and to what possible extent. Different pavement failure causative factors which include: Traffic load {T}, depth of water table {D}, soaked California bearing ratio {R}, cambering{A}, maximum dry density {M}, and asphalt thickness {S} were proposed. Their field data were analyzed and simulations were done to postulate a model for road failure susceptibility. The weights and ratings of the collected field data were also varied/modified to determine its effect on the model. Simulations on the varied weight showed that the most significant parameters were {T}Traffic load and {D}depth of the water table. The optimum weights were discovered to be 32 (81% weight increase) and 23 (78% weight increase) for {T}Traffic load and {D}depth to water table respectively. Simulations on the varied ratings showed that alongside with {R}soaked California bearing ratio [CBR], {T}Traffic load and {D}depth of water table were also the most significant parameters. The roads studied indicated high failure susceptibility when analyzed.
