Bin packing with directed stackability conflicts
Authors: Bódis Attila
Published: June 2015

The Bin Packing problem is a well-known and highly investigated problem in the computer science: we have n items given with their sizes, and we want to assign them to unit capacity bins such, that we use the minimum number of bins.

In this paper, some generalizations of this problem are considered, where there are some additional stackability constraints defining that certain items can or cannot be packed on each other. The corresponding model in the literature is the Bin Packing Problem with Conflicts (BPPC), where this additional constraint is defined by an undirected conflict graph having edges between items that cannot be assigned to the same bin. However, we show some practical cases, where this conflict is directed, meaning that the items can be assigned to the same bin, but only in a certain order. Two new models are introduced for this problem: Bin Packing Problem with Hanoi Conflicts (BPPHC) and Bin Packing Problem with Directed Conflicts (BPPDC). In this work, the connection of the three conflict models is examined in detail.

We have investigated the complexity of the new models, mainly the BPPHC model, in the special case where each item have the same size. We also considered two cases depending on whether re-ordering the items is allowed or not.

We show that for the online version of the BPPHC model with unit size items, every Any-Fit algorithm gives not better than -competitive, when it is forbidden for the optimum to re-order the items, even if only 2 stackability classes, called Hanoi classes, are applied. This lower bound is generalized for arbitrary number of Hanoi classes. However, we also prove, that asymptotically the First-Fit algorithm is 1-competitive for this case.

Finally, we introduce an algorithm for the offline version of the BPPHC model with unit size items, which has polynomial time complexity, if the number of the Hanoi classes and the capacity of the bins are constant.

If k ≥ 1, then the global degree set of a k-partite graph G = (V
1, V
2, . . . , V
k, E) is the set of the distinct degrees of the vertices of G, while if k ≥ 2, then the distributed degree set of G is the family of the k degree sets of the vertices of the parts of G. We propose algorithms to construct bipartite and tripartite graphs with prescribed global and distributed degree sets consisting from arbitrary nonnegative integers. We also present a review of the similar known results on digraphs.

The bio-corona and its impact on nanomaterial toxicity
Authors: Westmeier Dana , Chen Chunying , Stauber Roland H. , Docter Dominic
Published: June 2015

The rapidly growing application of nano-sized materials and nano-scaled processes will result in increased exposure of humans and the environment. The small size of nanomaterials (NM) comparable with molecular building blocks of cells raises concerns that their toxic potential cannot be extrapolated from studies of larger particles due to their unique physico-chemical properties. These properties are also responsible that NM rapidly adsorb various (bio)molecules when introduced into complex physiological or natural environments. As the thus formed protein/biomolecule ‘corona’ seems to affect the NM’ in situ identity, an understanding of its toxicological relevance and the biophysical forces regulating corona formation is needed but not yet achieved. This review introduces our current concept of corona formation and evolution and present analytical methods for corona profiling. We discuss toxicity mechanisms potentially affected by the biomolecule corona, including NM cellular uptake and impact on components of the blood system. Further, we comment on pending knowledge gaps and challenges, which need to be resolved by the field. We conclude by presenting a tiered systems biology-driven approach recommended to mechanistically understand the coronas’ nanotoxicological relevance and predictive potential.

Published: June 2015

In early 2000, two contamination events at Baia Mare first and Baia Borsa second involving large amounts of toxic elements impacted the Hungarian section of the River Tisza with disastrous ecological and economical impacts. We evaluated the sort- and long-term effects of this pollution by determining the total and bioavailable concentrations of potentially toxic metals from soil samples collected along the Tisza (Tivadar, Vásárosnamény, Rakamaz, and Tiszacsege) in 2000 and between 2011 and 2013. The current and previous results were compared in respect of copper and lead contents.
Groundwater Remediation Using Biological And Photocatalytic Methods
Authors: Guba Sándor , Somogyi Viola , Szabóné Bárdos Erzsébet
Published: June 2015

The degradability of two commercially available pesticides was studied using heterogeneous photocatalytic and activated sludge treatment methods. The first pesticide contained 5% quizalofop-P-ethyl as an active ingredient and petroleum naphtha as a solvent, the latter causing difficulties both in photocatalytic and biological treatment methods. The active ingredient of the second compound was acetamiprid. The photocatalysis proved to be effective both under laboratory conditions (using UV light) and when exposed to sunlight, but the pesticides remained stable during the employed biological treatment. Preliminary information on its behaviour in soil was obtained from transport modelling.
Simulation of Thermo-viscoplastic Behaviors for AISI 4140 Steel
Authors: Li Hong-Bin , Feng Yun-Li
Published: June 2015

The thermo-viscoplastic behaviors of AISI 4140 steel are investigated over wide ranges of strain rate and deformation temperature by isothermal compression tests. Based on the experimental results, a unified viscoplastic constitutive model is proposed to describe the hot compressive deformation behaviors of the studied steel. In order to reasonably evaluate the work hardening behaviors, a strain hardening material constant (h0) is expressed as a function of deformation temperature and strain rate in the proposed constitutive model. Also, the sensitivity of initial value of internal variablesto the deformation temperature is discussed. Furthermore, it is found that the initial value of internal variablescan be expressed as a linear function of deformation temperature. Comparisons between the measured and predicted results confirm that the proposed constitutive model can give an accurate and precise estimate of the inelastic stress–strain relationships for the studied high-strength steel.
Is International Ocean Law Capable of Preventing or Mitigating the Impacts of Nuclear Disaster?
Authors: Hutchins Todd Emerson
Published: June 2015

In light of the Fukushima disaster, the global community must honestly and bravely consider whether existing international law is sufficient to protect the oceans from hazardous nuclear activities past, present, and future. If so, are these agreements, including conventions and treaties, adequate to clean-up existing problems, to safeguard against emerging risks, and to foster cooperation among nations? If not, what function, does ocean law serve? Assessing the efficacy of international law on state behavior with respect to real world outcomes is always challenging, but when dealing with nuclear activities the task is further complicated due to the unusual risk profile of catastrophic radiological incidents, the millennia-long risk of danger, the relative novelty of nuclear issues, and the scope of other activities that could also impact the ocean. Nevertheless, this task cannot be ignored. The oceans are a global commons filled with collective resources. Any meaningful discussion about the health of the seas and measures to protect them must take place on the international stage with due regard for the necessities and rights of all nations, as well as the natural environment. The international community must diligently collaborate to resolve issues surrounding nuclear activities that could impact the oceans. Yet, current international agreements that address nuclear pollution of the ocean are de facto judicially unenforceable and are often ignored when national self-interest is contrary to the agreement. Nevertheless, while not an effective legal mandate, ocean law does in some cases influence state actors to conform to international agreements (even when not bound to do so). Going forward, more research is necessary into the impacts of radiological pollution on the oceans to enable decision makers, like judicial tribunals, politicians, and NGOs, to effectuate and effectively enforce international ocean law with respect to nuclear issues.
Towards a clean slate: Attempting to preserve civil liberty in the post-Snowden age
Authors: Gernler Alexander von
Published: June 2015

Wide adoption of mobile computing,
smartphones, social networks and big data techniques have brought
undoubtable advantages to society as such, as well as to its
individuals.
The downside of this diffusion of technology throughout society has
already been well discussed.
Single authors also pointed out the threats not only to the single
individual, but to democratic society as a whole.
However, suggestions or even practical approaches of how to mitigate
these threats not only at the individual level (Folks, keep your
virus scanner up to date all the time!), but for society itself,
are rarely found up to this day.
There is no simple solution to this problem, of course.
Particularly not a small one that can be carried out by a single
peer group.
Rather, we want to motivate that there are different approaches to
the shared common goal of preserving civil liberty for many individual
groups of society.
In this article, we focus on a strategy for computer
scientists on how to perform their part in the big picture, and try
to motivate this by calling up on their professional ethics.
Evaluation Of Shear Capacity For Brick Masonry Walls
Authors: Partene Eva , Fekete-Nagy Luminita , Stoian V.
Published: June 2015

The papers presents the results of an experimental program and provides valuable information regarding the behaviour of structural masonry walls built up using ceramic blocks with hollows, which represents a very common system for low-rise residential buildings, up to 4 stories, depending on the seismic acceleration on site. A number of six masonry walls where tested in bear state being subjected to constant vertical loading and to cyclic in-plane horizontal loads. The main objective was to determine the shear capacity for unreinforced masonry walls and reinforced masonry walls. The experimental results were also useful to determine the contribution of the reinforcing of the masonry walls with concrete columns. The comparison between unreinforced masonry and reinforced masonry has a great importance due to the fact that the Romanian Seismic Standards have imposed the reinforcement in seismic areas for building with more than 1 storey. Further studies will be conducted on strengthening the masonry walls using FRP materials.
Portfolio-work and its effects on listening comprehension of very young learners
Authors: Leeck Piri
Published: June 2015

At elementary school the focus often lies on listening and speaking. While listening comprehension is the basis for learning a new language, children often feel differently about that. Many measure their success in their ability to speak. Some become frustrated, because they initially are not able to express much, not noticing how much they understand already. In my research I tried to find a way to help such children appreciate more what they have achieved so far. Through portfolio-work (self-evaluation and reflection) I wanted them to see what is ‘unseen’, as well as get them to think about strategies that improve listening comprehension, as the following study report shows.
Crisis Communication and the Norwegian Authorities
Authors: Vettenranta Soilikki
Published: June 2015

The present article examines how crisis communication after catastrophes can strengthen society or undermine trust, credibility and confidence between the authorities and the general public. The two cases examined are the Norwegian authorities’ communicative response to the Chernobyl power plant disaster on 26 April, 1986, and the terrorist attacks on the government complex in Oslo and the Labour Party youth camp on the island of Utøya on 22 July, 2011. The analysis compares the initial phase of crisis communication. A serious communication crisis arose between the authorities and the public after Chernobyl, while communication during the early days after 22 July was successful. The difference is explained by the concept of rationality; crisis communication after Chernobyl was based on technical rationality, whereas communication after the terror attacks was grounded on the rationality of caring. The theoretical framework originates from Heidegger’s existential phenomenology with special focus on the existentiales Being-in-the-World, State of Mind and Care.
Morpholithodynamic conditions of the tip of the Hel Peninsula, the Baltic Sea
Authors: Rucińska-Zjadacz Maria , Rudowski Stanisław
Published: June 2015

The Hel Peninsula is a 35 km long spit that extends into water depths of almost 60 m. Unlike most sandy barriers, the distal end of the Hel Peninsula is prograding into the deep water. This affects unique conditions for the evolution of this section of the Peninsula. The aim of this study is to determine the morpholithodynamic changes on the tip of the Hel Peninsula. Shore studies were performed in 2006-2008 and 2012. Measurements included: beach profiling, determination of shoreline and dune base line positions, and collection of sediment samples. The different nature of the eastern, central and western part of the Hel tip is evident. The eastern part is accumulative, the central part is variable with the general nature of strong and differently directed redeposition and accumulative periods, while the western part is highly erosive.
Conformational preferences for isomeric N,N′-bis(pyridin-n-ylmethyl)ethanedithiodiamides, n = 2, 3 and 4: a combined crystallographic and DFT study
Authors: Zukerman-Schpector Julio , Madureira Lucas Sousa , Poplaukhin Pavel , Arman Hadi D. , Miller Tyler , Tiekink Edward R.T.
Published: June 2015

Crystal structure analysis of the isomeric N,N′-bis(pyridin-n-ylmethyl)ethanedithioamides, n = 2 (1), 3 (2) and 4 (3), show a planar conformation for 1 and conformations whereby the pyridyl rings lie orthogonal and to either side of the central residue for each of 2 and 3. The universal adoption of the all ZZ conformation about the central C–N bonds, which have double bond character, is ascribed to the presence of intramolecular N–H…S hydrogen bonds that close S(5) rings. The gas-phase geometry optimised structure for 1 is the same as the experimental structure which features intramolecular amine-N–H…N(pyridyl) hydrogen bonds. The open structures found for 2 and 3 differ from the somewhat flattened optimised structures. Systematic variations in the geometric parameters characterising the central C2N2S2 residue, in particular the double-bond character of the C–N bond and the elongation of the central C–C bond are shown by theory to be due to conjugative nN → π*C=S interactions and nS → σ*C-C hyperconjugation, respectively.

Published: June 2015

By using K4[Mo(CN)8] and [Ni(L)(H2O)2][ClO4]2 as reagents (L = 2,12-dimethyl-3,7,11,17-tetraazabicyclo [11.3.1]heptadeca-1(17),13,15-triene), a new cyanide-bridged Mo–Ni complex containing the building blocks [Ni(H2O)(L)]2+ and [Ni(L)]2+ bridged by [Mo(CN)8]4− units has been obtained. The complex with the formula {[Ni(H2O)(L)][Ni(L)][Mo(CN)8]}6 · 36H2O · 2CH3OH (1) was characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The structure determination reveals an octadecanuclear cluster in the form of a 36-membered macrocycle, in which the largest intramolecular W···W and Ni···Ni distances are 16.5 and 14.4 Å, respectively, indicating that complex 1 is a nanosized molecular wheel. Investigation of its magnetic properties has shown weak antiferromagnetic coupling between the adjacent Ni(II) ions bridged by the diamagnetic [Mo(CN)8]4− ions.
Alfred Loisy and les Mythes Babyloniens: Loisy’s Discourse on Myth in the Context of Modernism
Authors: Morrow Jeffrey L.
Published: June 2015

With the 1901 publication of his Les Mythes babyloniens et les premiers chapitres de la Genèse, the French Catholic scholar Alfred Loisy examined carefully parallels between Babylonian literature and the Book of Genesis. In German scholarship, this had been a growing fascination since at least the 1895 publication of Hermann Gunkel’s Schöpfung und Chaos in Urzeit und Endzeit. Loisy’s use of the concept of “Myth” provides an important window into the appropriation of German scholarship on religion and the Bible into the French scholarly world. Through Loisy’s work, what had been primarily a German Protestant academic discussion became one of the matchsticks that ignited what would become known as the Roman Catholic Modernist Crisis. This present article situates Loisy’s appropriation of “Myth” from the German scholarship he mastered within the proximate cultural, historical, and religious context that became Roman Catholic Modernism

Die nach dem K-Einfang an 68Ge-tetraphenyl gebildeten radioaktiven Rückstoßprodukte wurden mit denjenigen der (n, γ)-Reaktion am Ga-triphenyl und der (n, p)-Reaktion am Ge-tetraphenyl verglichen. Dabei wurde gefunden, daß bei den beiden Kernreaktionen mehrere Rückstoßverbindungen des Ga mit metallorganischem Charakter gebildet werden, im Gegensatz zum K-Einfangprozeß im 68Ge-tetraphenyl, aus welchem das 68Ga fast ausschließlich in anorganischer Form abgetrennt werden konnte. Es wird daraus gefolgert, daß bei der Elektroneneinfangreaktion des 68Ge im Ge-tetraphenyl keine sogenannten heißen Reaktionen stattfinden.

Authors: Parker W. , Bildstein H. , Getoff N.
Published: June 2015

A simple and rapid method is described for the production of carrier-free sodium-24 following the irradiation of magnesium with fast neutrons according to the nuclear equation : 24Mg (n, ρ) 24Na.

Based on the irradiation of MgO or Mg(OH)2 in the presence of water followed by extraction of 24Na also with water and with a final purification stage, involving ion exchange, the described method should prove very suitable for work at Curie level.

Detailed data are given for the pre-purification of the commercial magnesium target material and for its preparation as a slurry so as to take advantage of recoil products produced during the irradiation. Curves and data are presented showing the yield dependence on the water content of the magnesium target and of the efficiency of water as an extraction medium. In conclusion, the final purity of 24Na separated using the described method is discussed.

Le recuit thermique du coupferronate de fer irradié par neutrons
Authors: Rusi A. , Ionesco S.
Published: June 2015

On a étudié le recuit thermique du coupferronate de fer, Fe(C,H5-NO-NO), irradié par neutrons. Le trait essentiel de la cinétique de ce procès consiste dans la valeur unique des pseudoplateaux des isothermes effectuées de 60° à 100° C et de 105° à 110° C. On cherche à expliquer ces deux pseudo-plateaux en appliquant diverses théories existentes.

La représentation semilogarithmique des défauts soumis au recuit thermique (R∞ - Rt) donne une immage de la substitution du temps à la température pour aboutir au même pourcent de recuit. En représentant la propriété p
0 en fonction de l’énérgie d’activation E
0 (théorie de VAND et de PRIMAK), on obtient pour les diverses isothermes des courbes qui présentent d’autant plus haut maxima que la température est plus basse. Leur domaine d’énergies d’activations s’élargit aux températures plus élevées. Les maxima des courbes qui correspondent au premier plateau coïncident (0,995 eV). Les surfaces limitées par ces maxima sont à peu près égales (70°-100° C). Les courbes du deuxième pseudoplateau n’ont pas des maxima et sont deplacées de 0,05 eV vers de plus grandes énergies d’activation.

On suggère que l’existence des deux pseudoplateaux peut s’expliquer par des recuits dans les deux directions différentes, car les cristaux présentent une forme en aiguilles.

Adsorption and desorption of gold traces on glass were studied as a function of gold concentration, pH value and composition of the Solution using 198Au as indicator. The observations were explained on the basis of an ion exchange mechanism, the adsorbed species being the positively charged hydrolysed forms of gold. The influence of various complexing agents, of indifferent electrolytes and of the gold concentration on the adsorption was discussed.
Recent Developments in Material Microstructure: a Theory of Coarsening
Authors: Barmak K. , Eggeling E. , Emelianenko M. , Epshteyn Y. , Kinderlehrer D. , Sharp R. , Ta’asan S.
Published: June 2015

Cellular networks are ubiquitous in nature. Most engineered materials are polycrystalline microstructures composed of a myriad of small grains separated by grain boundaries, thus comprising cellular networks. The recently discovered grain boundary character distribution (GBCD) is an empirical distribution of the relative length (in 2D) or area (in 3D) of interface with a given lattice misorientation and normal. During the coarsening, or growth, process, an initially random grain boundary arrangement reaches a steady state that is strongly correlated to the interfacial energy density. In simulation, if the given energy density depends only on lattice misorientation, then the steady state GBCD and the energy are related by a Boltzmann distribution. This is among the simplest non-random distributions, corresponding to independent trials with respect to the energy. Why does such simplicity emerge from such complexity? Here we describe an entropy based theory which suggests that the evolution of the GBCD satisfies a Fokker-Planck Equation, an equation whose stationary state is a Boltzmann distribution.

Polyostotic Juvenile Ossifying Fibroma: An Exceptionally Rare Case
Authors: Wong Wendy W. , Motakef Saba , Martin Mark C.
Published: June 2015

Accurate and early diagnosis of benign fibroosseous lesions is important because the treatment and resulting outcomes of each differ. Juvenile ossifying fibromas typically occur in young patients and grow rapidly with a high recurrence rate. Their monostotic nature has previously differentiated these tumors from other fibroosseous lesions. We describe an interesting and extremely rare case of polyostotic juvenile ossifying fibromas in a 14-year-old boy with involvement of the maxilla and mandible. The available literature on juvenile ossifying fibromas is also briefly reviewed. When diagnosing a polyostotic fibroosseous lesion, it is important to not exclude the possibility of juvenile ossifying fibromas because this may warrant a different treatment.

Bilateral Crush Injury of the Proximal Tibial Physis in an Adolescent Gymnast
Authors: Balazs George C. , Polfer Elizabeth M. , Jex Jefferson W.
Published: June 2015

Case:

A thirteen-year-old female gymnast experienced bilateral knee pain after landing from a jump off a vault during a competition. Initial radiographs revealed negative findings, but magnetic resonance imaging demonstrated periphyseal osseous edema of the proximal parts of the tibiae. The patient later developed an anterior physeal bar on the right side, with recurvatum deformity.

Conclusion:

Despite similar initial imaging findings bilaterally and identical mechanisms of injury, only the injury on the right side met the strict criteria for classification as a Salter-Harris type-V injury. This case illustrates the difficulty encountered with current diagnostic criteria for type-V injuries.
My Goodness, My Heritage! Constructing Good Heritage in the Irish Economic Crisis
Authors: Lagerqvist Maja
Published: June 2015

In 2008, the Republic of Ireland entered a severe financial crisis partly as a part of the global economic crisis. Since then, it has seen large raises in income taxes and cuts in state spending on health, welfare, education and on heritage, which has suffered relatively large cuts. This implies a need for rethinking choices and prioritisations to cope with the changing circumstances. Across Europe, the effects of the crisis on heritage, or the whole cultural sector, have yet mostly been highlighted in general or supposed terms rather than empirically analysed. But what actually happens to how heritage is conceptualised in times of crisis? Inspired by Critical Discourse Analysis, this paper explores representation of and argumentation for heritage in Irish state heritage policies pre and post the recession 2008. Much concerns regarding heritage management are discursively shaped. Policies, stating the authorised viewpoint, are thus key in the construction of heritage and its values in society. Recently, research has highlighted a shift towards more instrumentality in cultural policy due to wider societal changes. A crisis could influence such development. The analysis departs from an often-stated notion of heritage as a part of the Irish national recovery, but what does that imply? Focus is therefore put on how different representations of heritage and its values are present, argued for and compete in a situation with increasing competition regarding relevance and support. The paper shows how heritage matters are refocused, streamlined and packaged as productive, good-for-all, unproblematic and decomplexified in order to be perceived and valued as part of the national recovery. This includes privileging certain instrumental values, foremost economic, by means of specificity, space and quantification, while heritage’s contribution to social life, education or health, although often mentioned, are downplayed by being expressed in much more vague terms.
Efficiency and Privacy Enhancement for a Track and Trace System of RFID-Based Supply Chains
Authors: Chen Xunjun , Zhu Yuelong , Li Jiguo , Wen Yamin , Gong Zheng
Published: June 2015

One of the major applications of Radio Frequency Identification (RFID) technology is in supply chain management as it promises to provide real-time visibility based on the function of track and trace. However, such an RFID-based track and trace system raises new security and privacy challenges due to the restricted resource of tags. In this paper, we refine three privacy related models (i.e., the privacy, path unlinkability, and tag unlinkability) of RFID-based track and trace systems, and clarify the relations among these privacy models. Specifically, we have proven that privacy is equivalent to path unlinkability and tag unlinkability implies privacy. Our results simplify the privacy concept and protocol design for RFID-based track and trace systems. Furthermore, we propose an efficient track and trace scheme, Tracker+, which allows for authentic and private identification of RFID-tagged objects in supply chains. In the Tracker+, no computational ability is required for tags, but only a few bytes of storage (such as EPC Class 1 Gen 2 tags) are needed to store the tag state. Indeed, Tracker+ reduces the memory requirements for each tag by one group element compared to the Tracker presented in other literature. Moreover, Tracker+ provides privacy against supply chain inside attacks.

Forêts et milieux ouverts : anciennes et nouvelles légitimités (Forests and open landscapes : old and new legitimacies)
Authors: Marty Pascal , Lepart Jacques
Published: June 2015

Abstract. - The example of the Grands Causses area (SE of Massif Central, France), shows that, during the twentieth century, the legitimacy granted to the woodland has strongly changed. At the beginning of XXe century, the origin of the open landscapes of the Grands Causses area is explained by the degradation of woodlands (regressive successions). Cutting, clearing and especially overgrazing are seen as the main causes of degradation. Agriculture and post-farming dynamics (progressive successions) are neglected. The planning conceptions are dominated by the projects of restoration and regeneration of woodlands. Since the Seventies, the interest of open landscapes and ovine breeding is highlighted. Main planning objective is now to preserve open landscape from reafforestation and from natural dynamics of woody plants. But it seems that grazing, in the current economic context, is not enough to stop woody plants dynamics and that landscape planning objectives will have to be redefined.

Intérêt culturel avant tout, qui trouvera une réponse dans l'action du "Comité flamand de France". Pendant la Première Guerre mondiale, les activistes flamands demandent aux Allemands l'incorporation de la Flandre française dans l'Etat flamand. Après la guerre, l'abbé Gantois érige le Vlaamsch Verbond voor Frankrijk, d'inspiration culturelle, mais il subit de plus en plus les influences nationalistes flamandes. Ce qui l'amène en 1940, après l'occupation allemande, à demander à Hitler l'incorporation de la Flandre française dans les Pays-Bas réunis. De même, le Chef du mouvement nationaliste flamand demande l'unification des Pays-Bas. Plusieurs publications de nationalistes flamands, plusieurs discours de dirigeants VNV illustrent cette exigence par la culture commune, mais aussi par des besoins économiques, par la notion de l'espace vital. En 1942, toutefois, les Allemands interdisent la notion "Pays-Bas réunis" : cette idée n'entrait plus dans les concepts allemands sur l'Europe nouvelle.
Concurrences et complémentarités des villes et des campagnes : les manufactures picardes de 1780 à 1815
Authors: Engrand Charles

Charles Engrand, "Concurrentie en samenwerking tussen de stad en het land : de picardische fabrieken tussen 1780 en 1815".

Op het einde van het Ancien Régime waren de industrieën van wol en laken in Picardie indrukwekkend ; er stonden tienduizenden getouwen in stad en land en talloze spinsters zorgden voor draad. De zeer verscheiden organisatiemodellen van de productie hadden een ding gemeen de laattijdige tussenkomst van de grote handel in het proces.

De industrie werd zwaar getroffen door de oorlog die na 1792 de export belemmerde. Het ineerstorten van de markt van wol en laken effende de weg voor het spinnen en weven van katoen dat tijdens de Keizertijd in Amiens en Saint-Quentin geconcentreerd was, waar de productie aangepast was aan de kennis van de arbeiders.

Op het land waar de werkkrachten goedkoop waren werden op grote schaal de stoofen geweven en dan later in de stad afgewerkt. Maar de spinnerij werd in de steden geconcentreerd, zodat de landelijke ateliers meer dan vroeger van de stad afhingen. Dat was een gevolg van de mechanisatie die later aile textielbedrijf op het land zou bedreigen.
Les centuriations romaines de la cité des Rêmes (I). Recherches sur l'aménagement de l'espace rural dans la province de Belgique
Authors: Jacques François

François Jacques, "De Romeinse centuriaties van het gebied van de Rémi (P). Opzoekingen in verband met de inrichting van de rurale streken in de provincie België".

Deze antieke verdeling van het land bepaalt nog steeds het landschap zowel op de uit- getstrekte plateau's van Champagne (tot ten zuiden van Châlons-sur-Marne) als in zones met meer relief (zoals de streek van Mouzon sur la Meuse). Dit onderzoek is beperkt tot de zone die de topografische kaarten van Reims en van Mourmelon-le-Grand beslaat. Men treft praktisch overal overbli- jfselen van centuratie aan, ook in de sectoren die artificieel bebost werden (Montagne de Reims).
Le marais de Saint-Omer
Authors: Derville Alain
Published: June 2015

The marsh adjoining Saint-Omer is a small and very original natural region but it is much threatened to-day. We have attempted to reconstitute its life and aspect in the pre-industrial period (XIIIh-XVIIIth century) and even its natural aspect before the great works of the XIIth century".

Following this we study the conquest of this marsh by men, conquest which started during the carolingian period and was completed in the XIIth century when the burghers of Saint-Omer established their fluvial link with Gravelines and the North Sea in two stages, first about 1 100 for 6-ton boats, then about 1 160 for 300-ton sea-ships and sometimes more. During this time countrypeople, monks and canons, lords and peasants had achieved a complete hold of the land and water in the marsh.

By stydying the archives in Saint-Omer we can discover the life of the marsh at the end of the Middle Ages and perceive its various aspects more closely : marketgardening around the town, meadows, peat-bogs and fishing on the border of tne marsh and, in the centre, the commons belonging to the burghers of Saint-Omer, which were a real polder dried by windmills.
Youden’s Index and the Likelihood Ratio Positive in Diagnostic Testing
Authors: Böhning D.
Published: June 2015

We refer to a recent letter to the editor by Hughes [1] and show that, despite existing similarities between Youden’s index and the log-likelihood ratio positive, important differences between these two measures remain to exist which can play an important difference in clinical practice.
Human Resource Management and Sustainable Tourism Development
Authors: Chand Dhiman Mohinder , Dahiya Ashish
Published: June 2015

Research on human resource management (HRM) practices and sustainable development has increased in the tourism management literature over recent decades. Scholars suggest that commitment-based HRM practices contribute to the sustainability of the firm; however, prior research puts little emphasis on the conceptual relationship between sustainable tourism development and commitment based HRM practices. This chapter opens the black box by examining the role and contribution of HRM in achieving sustainable tourism development in India. The findings of the study suggests that the new HR competencies required for achievement of sustainable tourism development and the applicability of HRM pervades every aspect of doing business and needs to be embedded across an organizational all levels, becoming an ongoing change process. Subsequently, tourism innovation activities enhance destination performance, emphasizing their determinant role to achieve sustainable tourism development in the digital age.
Privacy as a Right
Authors: Kiltidou Despina
Published: June 2015

This chapter examines not only the history of the term privacy but also its international recognition as a fully protected right. Given the wide array of definitions of privacy, it can be said that the term seeks its identity. Depending on time and space, this right has had various traits, beyond the obstacles of a strict definition. The aspects or features of the term are those that lead to the necessity of its international recognition and protection, especially in the present digital and technological environment, where its foundation is reconsidered and internationally protected in an effective way.
Multi-Level Adaptation in End-User Development of 3D Virtual Chemistry Experiments
Authors: Liu Chang , Zhong Ying
Published: June 2015

Multi-level adaptation in end-user development (EUD) is an effective way to enable non-technical end users such as educators to gradually introduce more functionality with increasing complexity to 3D virtual learning environments developed by themselves using EUD approaches. Parameterization, integration, and extension are three levels of adaptation ranging from straightforward to complex in terms of what end users have to understand in order to develop functional software applications, all within reach of end users without special training on programming. A 3D educational application EUD system prototype, iVirtualWorld, has been expanded to support 3D virtual chemistry experiments generation using these three levels of EUD adaptation. An evaluation has been conducted on 18 participants from the education domain, and the results confirmed ease-of-learn, ease-of-use, and usefulness of this solution. Contributions of this paper are 1) a paradigm for applying EUD technologies in 3D virtual learning environment creation; 2) an easy-to-use tool for educators to build customized virtual chemistry experiments; and 3) empirical assessment data for the multi-level adaptation solution.
Justifying the ROI of Social Media Investment in Education
Authors: Benson Vladlena , Morgan Stephanie
Published: June 2015

To invest or not to invest? In the context of Higher Education, the decision around social media adoption is ultimately driven by the end users—students—increasingly demanding in their expectations of technology support provided by universities. This presents a new set of challenges to HE institutions of how to effectively adopt social media in a range of modes provided to students, alumni, external stakeholders, etc. This chapter sets the agenda for future research into methods of measuring effectiveness of social media applications in Higher Education. Drawing on a rich account of social media applications throughout the entire student lifecycle, the chapter identifies common objectives to social media campaigns and uses in educational settings. A framework for social strategy adoption by HE institutions is proposed for further empirical testing. The chapter provides an approach to measuring the effectiveness of social media in higher education and offers practical recommendations and identifies areas needing future research.
Students' Out-of-School Writing Practices in an Educational Facebook Application
Authors: Gibbins Thor , Greenhow Christine
Published: June 2015

In this chapter, the authors seek to help educators understand trends in students' writing outside of the classroom, with a particular emphasis on illuminating students' purposes and practices in writing within social media spaces. The authors synthesize current research on students' Internet and social media practices and offer a case study from their own research on students' writing within an educational Facebook application called Hot Dish. This chapter seeks to elucidate the reciprocal relationship between students out of school writing using popular social media and their in-school practices. Ultimately, the authors seek to help readers make connections between what students are doing with new media in their leisure time and the improvement of students' writing performance in K-12 settings, believing there may be important but under-explored synergies.
Sarcoglycan complex in masseter and sternocleidomastoid muscles of baboons: an immunohistochemical study

The sarcoglycan complex consists of a group of single-pass transmembrane glycoproteins that are essential to maintain the integrity of muscle membranes. Any mutation in each sarcoglycan gene causes a series of recessive autosomal dystrophin-positive muscular dystrophies. Negative fibres for sarcoglycans have never been found in healthy humans and animals. In this study, we have investigated whether the social ranking has an influence on the expression of sarcoglycans in the skeletal muscles of healthy baboons. Biopsies of masseter and sternocleidomastoid muscles were processed for confocal immunohistochemical detection of sarcoglycans. Our findings showed that baboons from different social rankings exhibited different sarcoglycan expression profiles. While in dominant baboons almost all muscles were stained for sarcoglycans, only 55% of muscle fibres showed a significant staining. This different expression pattern is likely to be due to the living conditions of these primates. Sarcoglycans which play a key role in muscle activity by controlling contractile forces may influence the phenotype of muscle fibres, thus determining an adaptation to functional conditions. We hypothesize that this intraspecies variation reflects an epigenetic modification of the muscular protein network that allows baboons to adapt progressively to a different social status.
