Efficiency Boosting in Technical Grade Sugar Surfactant Based Microemulsions Using Pluronics
Authors: Hoehn Sebastian , Schulreich Christoph , Hellweg Thomas
Published: January 2014

The high amount of surfactant needed to formulate a bicontinuous microemulsion is a limiting factor for industrial usage of these systems. Commercially available triblock copolymers can be obtained in high amounts. Here, we show the influence of size and composition of different poly(ethyleneoxide)-poly(propyleneoxide)-poly(ethyleneoxide) triblock copolymer surfactants (Pluronics) on a technical grade sugar surfactant microemulsion. The so-called efficiency boosting can also be realized in such technical grade systems. The resulting efficiency boosting is studied systematically with regard to the impact of the polymer size and the composition of the system.
Study of Surfactant (Benzyldimethylhexadecylammonium Chloride) Effect on Selected Properties of Hydrogels
Authors: Herdová Petra , Vitková Zuzana , Oremusová Jarmila
Published: January 2014

This paper aims to provide analysis of the influences of concentration changes of the surfactant – benzyldimethylhexadecylammonium chloride in hydrogels on their liberation, rheological, association and solubility properties. The hydrogels contained constant amounts of the gel-creating basis (polymer chitosan – 2.5 % w/w), the drug (chlorhexidine dihydrochloride – 0.1 % w/w) and the surfactant, which was used as an enhancer (0.005 – 0.05 % w/w). The highest value of the released drug corresponded to the highest surfactant concentration in the hydrogel. Critical micelle concentration and thermodynamic parameters, molar Gibbs energy, enthalpy and entropy of micellization were calculated. A linear increase of the surfactant amounts in hydrogels caused a non-linear increase of the cloud point. The appearance of the surfactant's associates in hydrogels influenced both their liberation and rheological properties.
Physicochemical Properties of Quaternary Ammonium Surfactants with Hydroxyethyl Groups
Authors: Wang Ruitao , Li Yunling , Li Qiuxiao
Published: January 2014

Two cationic quaternary ammonium surfactants with hydroxyethyl groups, dodecyl-(2-hydroxyethyl)-dimethylammonium chloride (DHDAC), and dodecyl-di(2-hydroxyethyl)-methylammonium chloride (DHHAC) were synthesized. Their physicochemical properties were investigated systematically by surface tension and conductivity measurements. Various physicochemical parameters were calculated to evaluate the surface activities of these surfactants. The results show that the surface activity increases with increasing the number of hydroxyethyl groups on hydrophilic groups of surfactants. The degrees of counterion binding to micelles of these surfactants were also discussed. The thermodynamic parameters obtained from electric conductivity measurements show that the micelle formation of DHHAC is entropy-driven in the temperature range investigated. However, it is enthalpy-driven for DHDAC.

Authors: Alam Sultan , Amin Noor-ul , Bangash F. K. , Ali Mohammad
Published: January 2014

Indigenous kaolin was collected from Swat district and then activated. The samples were characterized by BET surface area, FTIR, XRD, SEM, EDS, TGA/DTA, zeta potential and particle size analysis. Adsorption of basic red 5 on each sample was studied by adsorption kinetics at 20 °C, 30 °C and 40 °C. The residual concentration of the dye was determined by using UV–Vis spectrophotometer. The removal of basic red 5 from water solution was studied with respect to dye concentrations and equilibration time. Adsorption kinetics on kaolinite surface were analyzed by using parabolic diffusion, Elovich and Bangham models. Thermodynamic parameters like ΔE#, ΔH# and ΔS# were calculated from the adsorption kinetics data. The results show that the adsorption is a spontaneous and endothermic process. The negative value of entropy shows that the dye molecules take a proper position on the surface.
The promise and practice of service learning and engaged scholarship
Authors: Urciuoli Bonnie
Published: January 2014

Service learning and other engaged scholarship programmes ideally operate in an academic framework to enhance student understanding of citizenship and community engagement. In reality, given the constraints on institutional budgets, such programmes are likely to be underfunded and academically understaffed. Structured as choices on an institutional menu, programmes are routinely touted as transformative though what they transform may be indeterminate. The ways in which such programmes are presented encourage students to interpret transformation as personal experience, valued to the extent that students can do good in the world by acting as agents of progress, solving problems for people imagined to need their expertise, ideally in exotic settings as unlike students' routine lives as possible, while students develop skills and connections useful in their post-college careers. This construction of engaged scholarship readily lends itself to institutional promotional language but can undermine students' effective action in actual projects.
The 'Real Experience' industry: Student development projects and the depoliticisation of poverty
Authors: Hickel Jason
Published: January 2014

Participation in development projects in the Global South has become one of the most sought-after activities among American and British high school graduates and college students. In the United States this often takes the form of Alternative Spring Break trips, while in Britain students typically pursue development work during their 'gap years'. Development projects offer students a way to craft themselves in an alternative mould, to have a 'real experience' that marks them off from the cultural mainstream as 'authentic' individuals. The student development craze represents an impulse to resist consumerist individualism, but this impulse has been appropriated and neutralised by a new logic of consumption, transforming a profoundly political urge for change into a form of 'resistance' compatible with neoliberal capitalism. In the end, students' pursuit of self-realisation through development has a profoundly depoliticising effect, shifting their attention away from substantive problems of extraction and exploitation to the state of the inner self.
Dreaming in green: Service learning, global engagement and the liberal arts at a North American university
Authors: Cororaton Claire , Handler Richard
Published: January 2014

This article documents and analyses the uneasy, if not contradictory, relationship between service learning and liberal arts thinking in an undergraduate programme in Global Development Studies (GDS) at a North American University. As an undergraduate, Cororaton participated in a service-learning project to build a greenhouse in Mongolia; at the same time, the curriculum of her major (GDS, a programme directed by Handler) was developing a critique of such service projects, focusing on their lack of political self-consciousness. The authors contextualise the story within the university's ongoing attempts to enhance its global profile.

Direction for the management of alpine hazards in times of climate change (essay)

Adapting to climate change means not only having to consider changing climate parameters but also to actively deal with societal change. Natural hazard management must therefore get involved in regional deliberation processes regarding future societal developments and consider these developments during the planning process.
Optimization of Three-Step Method For Biodiesel Production From Waste Cook Oil
Authors: Ferdous Kaniz , Uddin M Rakib , Uddin M Rahim , Khan Maksudur R , Islam MA
Published: January 2014

In this paper, production of biodiesel from Waste Cook Oil (WCO) by three-step method and optimization of the process were studied. The properties of raw oil were measured by standard methods. The raw oil containing 1.9 wt% Free Fatty Acid (FFA) and viscosity was 54.53 mm2/s. Biodiesel was prepared from WCO by three-step method. In the three-step method, the first step was saponification of the oil followed by acidification to produce FFA and finally esterification of FFA to produce biodiesel. The reaction parameters in saponification, acidification and esterification reaction were optimized. Silica gel was used during esterification reaction to adsorb water produced in the reaction and silica gel to FFA ratio was 1.5:10 wt/wt. Hence the reaction rate was increased and finally the FFA was reduced to 0.98 wt%. A factorial design was studied for esterification reaction to obtain the higher yield of biodiesel. Finally various properties of biodiesel such as FFA, viscosity, specific gravity, cetane index, pour point, flash point etc. were measured and compared with biodiesel and petro-diesel standard.

Extraction of Pectin from lemon peel: Technology development
Authors: Salma MA , Jahan N , Islam MA , Hoque MM
Published: January 2014

Pectin is widely used as a gelling agent, thickener, emulsifier and stabilizer in different food processing operations. Chemically it represents a polysaccharide, which is present in different amount in cell walls of all land plants. But citrus fruit is very rich in this component and can be used as source for its production commercially. In this study, lemon peel was selected as a representative of the citrus fruit family to extract pectin because of the abundance of the fruit in Bangladesh. Grounded lemon peel was digested in a solution of 0.01N HCl at a temperature of 80-90°C for 1.5 hours. The solid mass is filtered out and the filtrate is treated with different low molecular weight alcohol such as methanol, ethanol and isopropanol to precipitate the pectin out. The precipitate is dried at 40°C under vacuum. The structure of the product is yet to confirm by Fourier transform infrared spectroscopy (FTIR) analysis. The product is characterized by the parameters as methoxyl content, anhydrouronic acid content, degree of esterification, equivalent weight and intrinsic viscosity. The characteristic parameters are found to be in the same range as those shown by the product proposed in the market as Pectin. The yield of pectin extracted by the present method is as low as 1.08~1.38%, which is too low to make the method feasible for commercial purposes. Researchers are underway to improve the yield as well quality of the product.

Pharmaceutical Waste Water Treatment & Related Economic Aspects for Reuse in the Context of Bangladesh
Authors: Afreen Sadia , Paul Smita
Published: January 2014

The purpose of the work is to investigate the scenario of waste water treatment in pharmaceutical industries in Bangladesh and find some advanced steps to add in the existing ETP with economic considerations. For this, a renowned pharmaceutical industry in Bangladesh has been chosen that represents the feature of ETP in Bangladesh. Generally industries, including pharmaceuticals, discharge their waste water to the environment after treatment; the objective is to show some beneficial ways to use/reuse the treated water, applicable for the pharmaceutical industries in Bangladesh. Sample has been provided by ACI Pharmaceuticals Ltd. and different parameters of their supplied samples (both from inlet and outlet) have been measured to check whether they suit with the present standards of drinking water and/or other standards of industrial discharged water in context of Bangladesh. From the experiment it is found that the values of the different parameters of the treated water of the chosen industry can be considered to be favorable in comparison with the present standards of waste water regulations in Bangladesh. The present investigation also shows that if an ion exchange unit or membrane separation technology is incorporated after filtration, the waste water can be made potable after treatment by implementing some advanced technology DOI: http://dx.doi.org/10.3329/jce.v27i2.17801 Journal of Chemical Engineering, IEB Vol. ChE. 27, No. 2, December 2012: 46-49
Study of Hydrate Formation and Inhibition for LPG
Authors: Sarker Mridul , Chowdhury Debasish , Hossain Iqbal
Published: January 2014

Liquefied petroleum gas (LPG) has already been proved as an efficient fuel and feedstock for many chemical and petrochemical industries. Hydrate formation can create serious problems in the production, transmission, storage, and end-use of LPG. Hence an adequate knowledge on hydrate formation (i.e., the effects of moisture content and pressure on the hydrate formation temperature) is crucial to maintain the process conditions out of the hydrate formation region. However the study particularly on such aspects is scarcely available in literature. Therefore the effects of moisture content and pressure on the LPG hydrate formation temperature are studied extensively. A correlation is also developed to predict hydrate formation temperature for various LPG compositions. Hydrate inhibition performances of various inhibitors are also evaluated. Aspen-HYSYS process simulator is used to perform the study. The present study provides useful information to reduce the hydrate formation of LPG.

Introducing Disappointment Dynamics and Comparing Behaviors in Evolutionary Games: Some Simulation Results
Authors: Patokos Tassos
Published: January 2014

The paper presents an evolutionary model, based on the assumption that agents may revise their current strategies if they previously failed to attain the maximum level of potential payoffs. We offer three versions of this reflexive mechanism, each one of which describes a distinct type: spontaneous agents, rigid players, and ‘satisficers’. We use simulations to examine the performance of these types. Agents who change their strategies relatively easily tend to perform better in coordination games, but antagonistic games generally lead to more favorable outcomes if the individuals only change their strategies when disappointment from previous rounds surpasses some predefined threshold.

Retinol, α-tocopherol, and γ-tocopherol are fat-soluble vitamins acting as antioxidants via the prevention of lipid oxidation. Little is known about circulatory levels in healthy individuals. The present cross-sectional study aimed at elucidating the relationship between these antioxidants and clinical biomarkers in 206 male (median age 41 years, range 23–67) employees from companies located in the Okayama Prefecture, Japan. Subjects younger than 40 years (n = 94) showed a positive association of the frequency of alcohol consumption with the circulating retinol (β = 0.344, p = 0.001) and γ-tocopherol levels (β = 0.219, p = 0.041), and an inverse association of fast insulin with serum retinol (β = −0.301, p = 0.009). In participants older than 40 years (n = 112) we found that an inverse association of HOMA-R with serum retinol (β = −0.262, p = 0.021), α-tocopherol (β = −0.236, p = 0.035), and γ-tocopherol levels (β = −0.224, p = 0.052); and cigarette smoking was inversely associated with the levels of serum α-tocopherol (β = −0.286, p = 0.008) and γ-tocopherol (β = −0.229, p = 0.040). We further found negative relationships between serum ferritin and the retinol (β = −0.211, p = 0.032) and α-tocopherol levels (β = −0.223, p = 0.022) in men over 40 years of age. The present study suggests that the circulatory levels of antioxidant vitamins may modulate the action of insulin and that higher levels of iron might decrease the levels of antioxidant vitamins in the blood.

Published: January 2014

This paper reports a 17-year seroepidemiological surveillance study of Borrelia burgdorferi infection, performed with the aim of improving our knowledge of the epidemiology of this pathogen. Serum samples (1,179) from patients (623, stratified with respect to age, sex, season, area of residence and occupation) bitten by ticks in two regions of northern Spain were IFA-tested for B. burgdorferi antibodies. Positive results were confirmed by western blotting. Antibodies specific for B. burgdorferi were found in 13.3% of the patients; 7.8% were IgM positive, 9.6% were IgG positive, and 4.33% were both IgM and IgG positive. Five species of ticks were identified in the seropositive patients: Dermacentor marginatus (41.17% of such patients) Dermacentor reticulatus (11.76%), Rhiphicephalus sanguineus (17.64%), Rhiphicephalus turanicus (5.88%) and Ixodes ricinus (23.52%). B. burgdorferi DNA was sought by PCR in ticks when available. One tick, a D. reticulatus male, was found carrying the pathogen. The seroprevalence found was similar to the previously demonstrated in similar studies in Spain and other European countries.
Analysis of Ecological Quality of the Environment and Influencing Factors in China during 2005–2010
Authors: Wang Shi-Xin , Yao Yao , Zhou Yi
Published: January 2014

Since the twentieth century, China has been facing various kinds of environmental problems. It is necessary to evaluate and analyze the ecological status of the environment over China, which is of great importance for environmental protection measures. In this article, an Eco-environmental Quality Index (EQI) model is established using national remote sensing land-use data, NDVI data from MODIS and other statistical data. The model is used to evaluate the ecological status over China during 2005, 2008 and 2010, and spatial and temporal variations in EQI are analyzed during the period 2005–2010. We also discuss important factors affecting ecological quality, with special emphasis on meteorological conditions (including rainfall and sunshine duration) and anthropogenic factors (including normalized population and gross domestic product densities). The results show that, EQIs in northwestern China are generally lower than those in the southeast of the country, presenting a ladder-like distribution. There is significant correlation between EQI, rainfall and sunshine duration. Population density and GDP also have some relation to EQI. On the whole, the environmental quality results showed little variation during 2005–2010, with national average EQIs of 54.86, 55.07 and 54.43 in 2005, 2008 and 2010, respectively. During 2005–2010, differences in EQI were observed at the local level, but those at the provincial level were small.
Hyaluronic Acid Bioconjugates for the Delivery of Bioactive Molecules
Authors: Mero Anna , Campisi Monica
Published: January 2014

Hyaluronic acid (HA) has currently several therapeutic applications: in ophthalmology, osteoarthritis, wound healing, tissue regeneration, postoperative anti-adhesion and anesthetic medicine. In the last ten years, it has also been successfully investigated in the field of drug delivery, in the form of conjugates or hydrogel depot systems. HAylation, the covalent conjugation of HA to bioactive molecules, allows the overcoming of disadvantages associated with some pharmaceuticals, such as insolubility, instability and fast kidney clearance. These issues can be addressed also by covalent attachment of polyethylene glycol (PEGylation), but HA has the relevant advantages of biodegradability, high loading and specific targeting. In this review, the novel HA derivatives and the latest advances in HA-based drug delivery with a particular focus on the chemistry of conjugation will be discussed. Although, so far, there are no HA-drug conjugates on the market, several derivatives are presently under clinical investigation, and the promising results encourage further investigations and the exploitation of this versatile polysaccharide.
The Stalled Recovery of the Iraqi Marshes
Authors: Becker Richard
Published: January 2014

The Iraqi (Mesopotamian) Marshes, an extensive wetlands system in Iraq, has been heavily impacted by both human and climate forces over the past decades. In the period leading up to the Second Gulf War in 2002, the marshlands were shrinking due to both a policy of draining and water diversion in Iraq and construction of dams upstream on the Tigris and Euphrates rivers. Following the war through 2006, this trend was reversed as the diversions were removed and active draining stopped. A combination of MODIS and GRACE datasets were used to determine the change in surface water area (SWA) in the marshes, marshland extent and change in mass both upriver in the Tigris and Euphrates watersheds and in the marshlands. Results suggest that the post war dam removal and decreased pumping in 2003 provided only temporary respite for the marshlands (2003–2006 SWA: 1,477 km2 increase (600%), water equivalent depth (WED): +2.0 cm/yr.; 2006–2009: −860 km2 (−41%) WED: −3.9 cm/yr.). Unlike in the period 2003–2006, from 2006 forward the mass variations in the marshes are highly correlated with those in the upper and middle watershed (R = 0.86 and 0.92 respectively), suggesting that any recovery due to that removal is complete, and that all future changes are tied more strongly to any climate changes that will affect recharge in the upper Tigris-Euphrates system. Precipitation changes in the watershed show a reduction of an average of 15% below the 15 yr mean in 2007–2011 This corresponds with published ensemble predictions for the 2071–2099 time period, that suggested similar marshland shrinkage should be expected in that time period.

Housing : a long-term crisis ?

France''s current housing crisis appears to be here to stay, and is affecting housing prices and supply. The purpose of this article is to present the generally-accepted causes for this crisis, based on analysis of academic literature on the subject. Several factors contribute to the current situation. On the housing demand side, demographic factors are a structural cause. Population growth and the increasing number of households are creating growing tensions in local housing markets, affecting both sales and rentals. Meanwhile, on the supply side, land, investment and tax policies have had inflationary effects and led to properties being retained without improving the supply of rental properties in the places where there is the greatest need. Finally, personal housing benefits are allowing ever fewer renters to make ends meet.

Housing reform : advisory board opinions come up against political realities in the Netherlands

This article studies the way in which the world of politics is responding to the urgent need to reform the housing market in the Netherlands -a need acknowledged by more or less everyone -and examines the effectiveness and influence of university research and its recommendations on the political decision-making process. For reasons connected to the operation of the ruling political coalition, the Dutch government almost completely ignores the recommendations made by several advisory bodies, which suggest undertaking a substantial reform of the housing system in the Netherlands. Even though experts and interest groups are unanimous in the view that the existing housing system must be radically reformed, political considerations within the Netherlands'' ruling coalition apparently hold more weight when it comes to housing policy at present. It would therefore appear that, in recent years, researchers and their recommendations have had hardly any influence on the political decision-making process. This article attempts to understand the gulf separating university research from the political decisionmaking process on Dutch housing policy.

Ten polymorphic microsatellite primers in the tropical tree caimito, Chrysophyllum cainito (Sapotaceae)
Authors: Petersen Jennifer J. , Parker Ingrid M. , Potter Daniel
Published: January 2014

• Premise of the study: We developed microsatellite primers for the tropical tree Chrysophyllum cainito (Sapotaceae) to determine the native range of the species, investigate the origin of cultivated populations, and examine the partitioning of genetic diversity in wild and cultivated populations.

• Methods and Results: We developed 10 polymorphic primers from C. cainito genomic DNA libraries enriched for di‐, tri‐, and tetranucleotide repeat motifs. The loci amplified were polymorphic in samples collected from Jamaica and Panama. The number of alleles per locus ranged from two to 10 and three to 12, while observed heterozygosities ranged from 0.074 to 0.704 and 0.407 to 0.852 in Jamaica and Panama, respectively.

• Conclusions: The microsatellite primers will be useful in future population genetic studies as well as those aimed at understanding the geographic origin(s) of wild and cultivated populations.

Dans cet article centré sur un cas clinique, l’auteur s’intéresse aux troubles dermatologiques et souligne qu’une demande d’ordre somatique gagnerait à être entendue dans un cadre thérapeutique la resituant dans l’histoire personnelle du sujet. Il s’agirait de passer du traitement du corps organique, corps réel, à l’écoute du corps signifiant, corps symbolique, sans pour autant négliger le corps imaginaire. La souffrance non prise en charge par la parole se répercutant souvent dans le corps, il s’agirait de réserver au sujet la possibilité d’une traduction langagière du trouble somatique pour l’inscrire dans une réflexion sur le désir subjectif et le rapport à l’Autre parental et l’Autre social.
Introduction. Grand Paris : projet pour une métropole globale
Authors: Bourdeau-Lepage Lise
Published: January 2014

Depuis environ une dizaine d’année le débat sur le développement et l’aménagement de l’Île-de-France s’incarne autour de l’expression « Grand Paris ». Au-delà des controverses politiques et scientifiques sur l’avenir de la région capitale, trois enjeux majeurs, fortement liés, ont émergé. Il s’agit du développement économique et de la place de Paris dans le monde (Section 2), de la justice socio-spatiale et de la qualité de vie (Section 3) et de la gouvernance (Section 4), autant de clefs pour comprendre les projets et les évolutions en cours en région Île-de-France. L’objectif de ce papier, qui introduit le numéro spécial « Grand Paris », est d’alimenter une réflexion scientifique en explorant chacun de ces enjeux, à partir des principaux faits stylisés et du raisonnement sous-jacent des parties prenantes, tout en soulignant l’apport original des différents articles qui composent ce numéro.
« Grand Paris Express » : un projet au service de la réduction des inégalités d'accessibilité entre l'Ouest et l'Est de la région urbaine de Paris ?
Authors: Beaucire Francis , Drevelle Matthieu
Published: January 2014

Le projet de métro automatique circulaire dans la couronne de l’agglomération parisienne, appelé « Grand Paris Express » (GPE), augmente de façon considérable l’accessibilité interne de la région en créant de nouveaux points de desserte et un maillage avec la majorité des lignes radiales. Actuellement, l’accessibilité aux emplois est inférieure de 36 % dans la proche banlieue Est par rapport à la proche banlieue Ouest. La réalisation du GPE réduit considérablement les écarts d’accessibilité entre Est et Ouest, et plus généralement entre communes de petite couronne. Cependant, dans l’hypothèse où l’arc du proche Est (longtemps laissé en suspens) ne serait pas réalisé, les écarts d’accessibilité deviendraient considérables.
Quelle fracture socio-spatiale à l'heure du Grand Paris ? Le cœur de l'Île-de-France à la dérive
Authors: Bourdeau-Lepage Lise , Tovar Élisabeth
Published: January 2014

Dans cet article, l’augmentation des disparités de bien-être entre les communes franciliennes est étudiée à l’aide d’un indicateur de bien-être spatialisé inspiré par l’approche capabiliste de Sen. Cet indicateur original permet de tenir explicitement compte du rôle joué par la localisation résidentielle sur les réalisations, les opportunités et la liberté de choix. Le bien-être spatialisé augmente entre 1999 et 2006 et les communes les plus défavorisées rattrapent en moyenne les communes les plus favorisées. L’étude de l’auto-corrélation spatiale des niveaux de bien-être entre les communes révèle une forte polarisation des niveaux de bien-être les plus faibles sur le territoire francilien. Cette polarisation augmente sur la période et, même, certaines des communes les plus défavorisées voient leur niveau de bien-être diminuer pendant cette période. Cela pourrait expliquer la croyance collective d’une augmentation de la fracture socio-spatiale en Île-de-France.
Écologie territoriale et indicateurs pour un développement durable de la métropole parisienne
Authors: Audrain Johann , Cordier Mateo , Faucheux Sylvie , O’Connor Martin
Published: January 2014

Cet article traite de la dimension environnementale de la dynamique du « Grand Paris ». Il explique comment une approche d’écologie territoriale permet d’aborder les questions de gouvernance pour la métropole Parisienne. Nous présentons, dans un premier temps, des indicateurs synthétiques comme l’« empreinte écologique » et l’« empreinte environnementale », permettant d’appréhender l’ampleur de l’impact environnemental de la métropole. Ensuite, nous mettons en évidence, à partir d’une modélisation intégrée originale couplée à une analyse de scénario quantitative, le « métabolisme » du Grand Paris et, plus particulièrement, les impacts de l’activité économique du bassin de la Seine en amont sur l’écologie de l’estuaire de la Seine en aval. Les opportunités de politique territoriales suscitées par l’observation de la dégradation de l’estuaire sont démontrées. La nécessité d’accorder une place centrale à l’environnement dans toute vision stratégique des avenirs possibles de la mégapole parisienne devient alors explicite.
Conclusion. La gouvernance du Grand Paris au service de sa compétitivité
Authors: Vallerugo Franck
Published: January 2014

La compétitivité des territoires est une notion économiquement légitime qui connait un terrain d’application renouvelé dans le cadre du projet du Grand Paris. Des caractères « géographique » et « inclusif » de cette compétitivité sont mis en évidence à partir de l’analyse de l’offre de transport que constitue le Grand Paris Express, mais aussi du rôle de la gouvernance urbaine ; celle-ci est définie à partir de ses déterminants structurels et relationnels selon lesquels elle fait intervenir des acteurs non nécessairement institutionnels et induit un partage flou des responsabilités entre ces acteurs interdépendants et nécessairement respectueux de l’exercice d’une autorité régulatrice. La construction d’un dispositif de gouvernance assurant aux entreprises la liberté d’exprimer pleinement leur responsabilité territoriale pourrait alors permettre de nourrir les deux impératifs de compétitivité « géographique » et « inclusive » recherchés par le projet du Grand Paris.

eLearning will revolutionise higher education in the next decade. Although this has likely been said regularly over the last 20 years, the widespread availability of mobile devices, ubiquitous wifi connections, and the globalisation of industry, driven by global networking infrastructure, will finally deliver the promises of learning anytime anywhere. This chapter reviews the most common forms of eLearning, both synchronous and asynchronous: recorded lectures, learning management systems, online assessment, blogs, and wikis are slowly transforming education towards a student-centred model of learning. The question remains: what is the university’s business model when students can collect their learning resources for free from iTunesU?

Published: January 2014

Laboratory practice plays a crucial role in engineering and technology education. The advancement of computational and computer technologies have ushered in a new horizon in learning and teaching of laboratory practices worldwide. Apart from traditional hands-on laboratory practice, two other laboratories, namely the virtual/simulated laboratory and the remote control laboratory practices, are playing an increasingly dominant role. The virtual and remote laboratory practices offer unique opportunities for students to visualise complex concepts and remove the time and location barrier. This chapter provides a comparative analysis of all three laboratory practices. Additionally, a 3-step laboratory practice and a hybrid laboratory practice developed at RMIT University are described. It is evident that the advancement of computational technology enhances the student learning experience in laboratory practices. However, real world hands-on laboratory practices cannot be fully replaced by the virtual/simulated and/or remote control laboratory practices. They are complementary.
Multiobjective Analysis of the Multi-Location Newsvendor and Transshipment Models

Published: January 2014

Unlike the Newsvendor model, a system based on lateral transshipments allows the unsold inventories to be moved from locations with surplus inventory to fulfill more unmet demands at stocked out locations. Both models were thoroughly studied and researches were usually confined to cost minimization or profit maximization. In this paper, the authors proposed a more realistic multiobjective study of both multi-location Transshipment and Newsvendor inventory models. The aggregate cost, the fill rate, and the shared inventory quantity are formulated as conflicting objectives and solved using two reference multiobjective evolutionary algorithms (SPEA2 and NSGA-II). The proposed models take into account the presence of storage capacity constraints. The obtained Pareto fronts revealed interesting information. When transshipments are allowed, both low aggregate cost and high fill rate levels are ensured. The required shared inventory may have an important variability. The considered objective functions are conflicting and very sensitive to local storage capacities.
Communication in the Manufacturing Industry

Published: January 2014

This article is based on a case study of one shipyard’s effort to make the flow of engineering drawings feeding into its production process more reliable. To construct a ship, detailed drawings of every part of the product is an essential input. For these drawings to be reliable, they must include all relevant information, they have to follow each other in a proper line of order, and they should be released according to production milestones. In the shipyard in this study, an analysis was initiated to explore the management of engineering drawing. The main findings show that the usability of ICT is limited for this purpose, and that to really make an effort in order for engineering drawings to be reliable, a more basic understanding of the interpersonal communication at work in a one-off project environment is fundamental.
Privacy-Aware Web Service Composition and Ranking
Authors: Costante Elisa , Paci Federica , Zannone Nicola
Published: January 2014

Service selection is a key issue in the Future Internet, where applications are built by composing services and content offered by different service providers. Most existing service selection schemas only focus on QoS properties of services such as throughput, latency and response time, or on their trust and reputation level. By contrast, the risk of privacy breaches arising from the selection of component services whose privacy policy is not compliant with customers’ privacy preferences is largely ignored. In this paper, the authors propose a novel privacy-preserving Web service composition and selection approach which (i) makes it possible to verify the compliance between users’ privacy requirements and providers’ privacy policies and (ii) ranks the composite Web services with respect to the privacy level they offer. The authors illustrate their approach using an eCommerce Web service as an example of service composition. Moreover, the authors present a possible Java-based implementation of the proposed approach and present an extension to WS-Policy standard to specify privacy related assertions.
Consumer Privacy Enforcement in Context-Aware Web Services

Published: January 2014

Privacy protection constitutes a genuine human right reflected both in the legislation and in different aspects of software engineering. Sensitive information needs to be protected in end-users interaction with Web Services especially in cases, where context-aware features are included. In this work the authors address the inclusion of consumer privacy preferences in the provision of context-aware Web Services. To achieve this the authors propose, on the one hand, a preferences language, where end-users can specify their privacy options, namely Consumer Privacy Language, and, on the other hand, a seamless enforcement mechanism that considers consumer preferences by intercepting and modifying appropriately Simple Object Access Protocol request and response messages. The enforcement approach has been evaluated based on various execution metrics for an example use case consisting of various Web Services and for different users configurations demonstrating the usefulness of the approach assisting towards the provision of privacy-aware environments.

Published: January 2014

In order to build a low-latency and light-weight publish/subscribe (pub/sub) system for delay-sensitive IOT services, the authors propose an efficient and scalable broker architecture named Grid Quorum-based pub/sub (GQPS). As a key component in Event-Driven Service-Oriented Architecture (EDSOA) for IOT services, this architecture organizes multiple pub/sub brokers into a Quorum-based peer-to-peer topology for efficient topic searching. It also leverages a topic searching algorithm and a one-hop caching strategy to minimize the search latency. Light-weight RESTful interfaces make the authors’ GQPS more suitable for IOT services. Cost analysis and experimental study demonstrate that the GQPS achieves a significant performance gain in search satisfaction without compromising search cost. The authors apply the proposed GQPS in the District Heating Control and Information Service System in Beijing, China. This system validates the effectiveness of GQPS.
Today’s Action is Better than Tomorrow’s Cure - Evaluating Information Security at a Premier Indian Business School

Information Security breaches today affect a large number of organizations including universities, globally. They pose an immense threat to the C-I-A (confidentiality, integrity and availability) of information. Hence, it is important to have proper Information Security Management System (ISMS) designed in accordance with industry adopted standards for risk management. The current case explores the IT infrastructure at a premier Indian business school where internet support is required round the clock. The entire ISMS framework of the organization, including security policy, security budget and network components, is described. Though the security infrastructure apparently seemed to be adequate, a spate of hacking attacks targeted at the SMTP server attempted to cripple the extremely crucial email services for the period of the attack by generating spam. The primary security challenges facing the organization including nature and appropriateness of ISMS, adequacy of the security policy, budget allocation for IT security, etc., are left open for discussion. Mr. Rajesh Ghosh1, the Chairman, Computer Advisory Committee (CAC) at the ABC Institute of Management, Lucknow (AIML)1 looked at the dark brown, wooden floor of his office, immersed in thought about the latest hacking attempts on the Institute’s network. There was a knock on his partially open office door. Mr. Deepak Jha, the Computer Centre (CC) manager stood at the door with a pile of documents in his hand, smiled and said “It is not that bad after all. Our Computer Centre employees are trying their best to handle the attack and the situation will soon be under control.” Mr. Ghosh however, was more worried than relieved. It was the computer centre’s responsibility to provide safe and secure round the clock internet facility to the entire AIML community and it had always lived up to the expectations since its inception. However, of late there have been a few minor phishing attempts on the AIML network. Though all of them had been nipped in the bud, the current spate of hacking attacks on the AIML Simple Mail Transfer Protocol (SMTP) server had attempted to cripple the email services of the institute for a considerable period by generating spam. Mr. Ghosh wanted to ensure that the IT infrastructure at AIML was perfect and there were no loopholes in the network. As he prepared for his meeting with the CAC members, he pondered over the challenges related to the CC operations and services.
