A Logarithmic Safety Staffing Rule for Contact Centers with Call Blending
Authors: Pang Guodong , Perry Ohad 
Published: November 2014

We consider large contact centers that handle two types of jobs—inbound and outbound—simultaneously, a process commonly referred to as call blending. Inbound work arrives to the system according to an exogenous arrival process, whereas outbound work is generated by the contact center. We assume that there is an infinite supply of outbound work to process, and that inbound calls are prioritized over the outbound calls. We propose a logarithmic safety staffing rule, combined with a threshold control policy, ensuring that agents' utilization is very close to one at all times, but that there are practically always idle agents present. Specifically, we prove that it is possible to have almost all inbound calls answered immediately upon their arrival, in addition to satisfying a target long-run throughput rate of outbound calls, with at most a negligible proportion of those calls dropped. Simulation experiments demonstrate the effectiveness and accuracy of our analysis. This paper was accepted by Assaf Zeevi, stochastic models and simulation.
Determining the Processed Cut Stock Recovery Rate from Standing Dead Beetle-Killed Lodgepole Pine Timber
Authors: Mackes Kurt , Eckhoff Mike 
Published: November 2014

Abstract
Colorado's forests have been decimated by a mountain pine beetle outbreak. The mountain pine beetle introduces a blue-stain fungus into the trees, lowering the economic value of the wood. As a result, forest product manufacturing opportunities using beetle-killed trees are limited. One possibility is to use beetle-killed trees to make cut stock, which is lumber that has been cut into specified length, width, and thickness requirements from a cant, lumber, or glued-up panels. The White River Conservation District commissioned this study to determine if a relationship existed between the amount of time beetle-killed trees remain standing dead and the recovery rate for cut stock material from those trees. Conducted in north-central Colorado and south-central Wyoming, this study found that enough material does exist in beetle-killed lodgepole pine trees to produce cut stock but that a tree's diameter at breast height is a better predictor for the cut stock recovery rate from the logs rather than the time spent standing dead on the stump. Given the increasing likelihood that beetle-killed trees will blow down as time passes, incentives for increased beetle-killed wood utilization should be developed quickly.
Reduction of Turbidity of Beet Sugar Solutions by Mechanical and Chemical Treatment
Authors: Abdel-Rahman El-Sayed Ali , Floeter Eckhard 
Published: November 2014

Abstract
The presence of practically non-dissolvable small particles in sugar solutions can cause haze during application and has to be minimal. Intermediate storage of thick sugar juice becomes increasingly common practice. In particular juices treated with anti-scale agents appear to be prone to turbidity development. This work on turbidity mitigation reports results on both laboratory and industrial level experiments. Different filter aids were tested and led to reduced turbidity levels. At industrial and lab scale reductions in the order of 30–54% and 50–70% were achieved respectively, which however remains insufficient to resolve the problem. The chemical mitigation by reduction of the hardness of the juice either by sodium carbonate or by ion exchanger treatment was investigated. While the reduction of the calcium concentration by dosing of sodium carbonate turned out to be basically possible, this remains less practical than the utilization of cation exchangers. Furthermore, it was found that application of anti-scale agents causes a reduction on the particle sizes that are found in thick juice samples after 2 months storage. Turbidity values of these samples were, independent of dosage and type of anti-scale agent, twice as high as in reference samples.
Improved area-based deformation analysis of a radio telescope’s main reflector based on terrestrial laser scanning

Published: November 2014

AbstractThe main reflectors of radio telescopes deform due to gravitation when changing their elevation angle. This can be analyzed by scanning the paraboloid surface with a terrestrial laser scanner and by determining focal length variations and local deformations from best-fit approximations.For the Effelsberg radio telescope, both groups of deformations are estimated from seven points clouds measured at different elevation angles of the telescope: the focal length decreases by 22.7 mm when tilting the telescope from 90 deg to 7.5 deg elevation angle. Variable deformations of ± 2 mm are detected as well at certain areas. Furthermore, a few surface panels seem to be misaligned.Apart from these results, the present study highlights the need for an appropriate measurement concept and for preprocessing stepswhen using laser scanners for area-based deformation analyses. Especially, data reduction, object segmentation and laser scanner calibration are discussed in more detail. An omission of these steps would significantly degrade the deformation analysis and the significance of its results. This holds for all sorts of laser scanner based analyses.

Abstract

Background: The effects of Orchis anatolica plant roots on adult male mice testicular structure and function were explored and compared with those of the red Korean Panax ginseng.

Methods: Both plants were administered orally to two separate mice groups at a dose of 800 mg/kg/day for 35 days and compared with control group. After treatment, 5 mice of each group were sacrificed and total mice weights, reproductive organs’ weights, spermatogenesis, and androgenic serum markers were investigated. The remaining mice from all groups were allowed to mate with virgin female mice to explore male fertility potential.

Results: Results indicated that body and organs’ weights were increased significantly in mice treated with Orchis anatolica where only slight changes were observed in red Korean Panax ginseng treated and control mice. Intestinal testicular Leydig cells and germinal cells counts were elevated significantly in mice treated with Orchis anatolica plant when compared with the other two groups. Testicular dynamics parameters recorded in both testes and caudae epididymides were found to be increased only in Orchis anatolica treated mice. Although testosterone serum titer was observed to be elevated in both treated mice groups a marked elevation was observed only in Orchis anatolica treated mice. Follicular stimulating hormone blood serum titer was also elevated obtained in Orchis anatolica treated mice when compared with the other two groups. The fertility index of male mice treated with Orchis anatolica plant was enhanced to a greater value when allowed mating with virgin female mice if compared with male mice fertility index recorded in the other two groups.

Conclusions: We can conclude that Orchis anatolica plant could be more useful to improve testicular functions and structural parameters in mice when compared with red Korean Panax ginseng.

AbstractHyperphenylalaninemia (HPA) [phenylketonuria (PKU) and tetrahydrobiopterin (BH4) deficiencies] is rare inborn metabolic disease characterized by elevated phenylalanine level in body fluids. In Serbia, 62 HPA patients have been identified through newborn screening since 1983. However, pterin pattern analysis is not performed. We present a patient initially diagnosed and treated as classical PKU. At 3 years of age, during infection with H1N1 influenza A virus, the patient first developed a neurologic crisis with encephalopathy and dystonic movements. We suspected that the patient is the first case of BH4 deficiency identified in Serbia. Genetic analyses showed that the patient does not have disease-causing variants of the
The Existence and Reality of Negative Facts
Authors: Kühl Carl Erik 
Published: November 2014

AbstractThe problem of the existence of negative facts as truthmakers for negative propositions was introduced by Bertrand Russell in 1918. In the debate since then, most writers have tended to reject their existence, Russell himself being the most conspicuous exception. Two other strategies have been offered. The first, usually called incompatibilism, actually goes back to Plato, whereas the second, the totality fact theory, was introduced by D. M. Armstrong in 1997. The aim of this paper is to show the problematic character of some of the presuppositions shared by all three of the strategies mentioned above – presuppositions that figure in most of the current discourse on the subject. First, the concept of a negative proposition is not clear: one needs to make a distinction between grammatically negative propositions and “ontologically” negative ones. Second, it turns out that propositions may be ontologically negative in many ways, each of which may call for a different specific analysis with respect to the question of the existence of what would be the corresponding negative facts. Third, at the bottomline, it is shown that we need a concept of the existence or
The Meaning of “Meaning” from a Hermeneutic Point of View
Authors: Hedberg Petra 
Published: November 2014

AbstractWhat is the meaning of “meaning”, hermeneutically seen? How does the philosophical hermeneutics of Hans-Georg Gadamer relate to the different types of meaning that are at hand in other branches of philosophy, such as sentence meaning within analytic philosophy, uttered meaning within speech acts theory and the communicative/dialogical meaning of formal/transcendental pragmatics? The comprehensive framework of Gadamer’s hermeneutics forms the horizon of understanding of this paper, and of specific interest is how these different types of meaning relate to the hermeneutic framework. Can a hermeneutical sense of meaning be elaborated in contrast to these different senses of meaning? Or, can these different types of meaning, in a certain sense, also be seen as compatible with the wider hermeneutical framework of meaning?
(Im)politesse et gestion des faces dans deux types de situations communicatives: petits commerces et débats électoraux
Authors: Kerbrat-Orecchioni Catherine 
Published: November 2014

Résumé
L’objectif de cet article est à la fois théorique et descriptif: il s’agit de mettre à l’épreuve le modèle de la politesse comme face work élaboré par Brown et Levinson (1978, 1987) en le confrontant à deux types bien différents d’interactions authentiques se déroulant en France, les échanges commerciaux d’une part (plus précisément, ceux qui se déroulent dans les “petits commerces”) et les débats politico-médiatiques de l’autre (plus précisément, les débats de l’entre-deux-tours des élections présidentielles). Après avoir proposé un certain nombre d’aménagements au modèle “standard” (introduction de la notion de Face Flattering Act venant compléter celle de Face Threatening Act, et des catégories de “non-politesse” et de “polirudesse” venant compléter celles de “politesse” et d’“impolitesse”), on appliquera ces notions et catégories au double corpus d’analyse. La confrontation montre à la fois que celles-ci sont en gros opératoires, mais que leur application ne peut se faire sans la prise en compte des normes en vigueur dans les différents genres discursifs observés, normes qui déterminent de façon décisive la façon dont les locuteurs utilisent et interprètent les ressources que la langue met à leur disposition, en particulier en matière de politesse.
How dopamine shapes representations in auditory cortex
Authors: Puschmann Sebastian , Weis Tina , Thiel Christiane M. 
Published: November 2014

The neural representation of sound in the auditory cortex is not invariably predetermined by its acoustical properties, but it is constantly reshaped while the listener acquires new experiences. Such plastic changes are a prerequisite for lifelong learning and allow some degree of rehabilitation after brain injuries. Several neurotransmitter systems modulate these plastic changes. In this paper, we focus on how the neurotransmitter dopamine modulates learning-related plasticity in auditory cortex, and how animal and human research can complement each other in providing an experimental approach that has relevance for studying mechanisms of recovery of function
Prognose oraler (gingivaler) Plattenepithelkarzinome beim Hund nach chirurgischer Therapie
Authors: Kessler M. , Kühnel S. 
Published: November 2014

ZusammenfassungGegenstand und Ziel: Retrospektive Untersuchung von Hunden mit gingivalen Plattenepithelkarzinomen (PEK), bei denen therapeutisch eine Kieferresektion erfolgte.Material und Methoden: Die Auswertung erstreckte sich auf 40 Hunde. Patienten, bei denen keine Komplettresektion des Tumors erfolgte oder die Metastasen aufwiesen, erhielten eine adjuvante Chemotherapie mit Carboplatin. Ermittelt wurden Rasse und Alter der Hunde, Tumorlokalisation, Komplikationen und Überlebenszeit sowie prognostische Faktoren.Ergebnisse: Eine Rasseprädisposition konnte nicht festgestellt werden. Das mediane Alter betrug 9,5 Jahre (durchschnittlich 8,6 Jahre, Bereich 0,5–15,5 Jahre). Bei zwei Hunden (5%) bestand zum Zeitpunkt der Vorstellung eine Lymphknotenmetastasierung (N1). Die mediane Überlebenszeit (ÜZ) aller Patienten lag bei 44,8 Monaten. Bei 15 Tieren war der Tumor im Oberkiefer lokalisiert, bei 25 im Unterkiefer. Die mediane ÜZ der Hunde mit Unterkiefertumoren betrug 43 Monate (95%-Konfidenzintervall [95%-KI] 33–70), die der Tiere mit Tumoren im Oberkiefer 39 Monate (95%-KI 24). Ein signifikanter Unterschied in den Überlebenszeiten von Patienten mit Oberbzw. Unterkiefertumoren war nicht nachweisbar (p = 0,985). In der Multivarianzanalyse zeigte nur das Tumorstadium prognostische Bedeutung (p = 0,0047). Patienten mit Stadium N0 lebten median 44 Monate (95%-KI 36–80), die beiden Hunde mit Lymphknotenmetastasen (N1) überlebten 18 bzw. 70 Monate nach Kieferresektion und Chemotherapie. Bei fünf Tieren zeigte sich histologisch nur eine inkomplette Resektion. Die ÜZ dieser Patienten nach Kieferresektion und Chemotherapie lag zwischen 6 und 146 Monaten (median 24 Monate).Schlussfolgerung und klinische Relevanz: Die Prognose von gingivalen PEK ist abhängig vom Tumorstadium. Bei Komplettresektion weisen sie eine günstige Prognose auf, die Mehrheit der Patienten kann als geheilt betrachtet werden. Das angeblich malignere Verhalten kaudal im Kiefer gelegener PEKs ließ sich in dieser Studie nicht nachvollziehen. Auch Patienten mit lokalen Lymphknotenmetastasen können befriedigende Überlebenszeiten erreichen. Kieferresektionen haben eine niedrige Komplikationsrate und gehen mit gutem funktionellem Ergebnis einher.

Abstract
Objective—To compare the anesthetic efficacy and adverse effects associated with peribulbar injection of ropivacaine (1% solution) performed with and without ultrasound guidance (UG) in dogs.
Animals—15 dogs without ophthalmologic abnormalities.
Procedures—Each dog was sedated and anesthetized. A peribulbar injection of ropivacaine (1% solution; 0.3 mL/kg) was performed with UG in 1 eye and without UG in the contralateral eye (control). For each eye, the intraocular pressure (IOP) immediately after eye centralization and number of punctures were recorded; ophthalmic complications, postinjection corneal sensitivity (determined by Cochet-Bonnet esthesiometry), durations of the sensory and motor blockades (the latter determined as the interval to restoration of the vestibuloocular reflex, pupillary light reflex, and conjugate eye movement), and blockade quality were assessed in both eyes following anesthetic recovery.
Results—Needle placement was fully visualized in 8 of the 15 eyes injected with UG. For eyes injected with or without UG, there was no difference with regard to the number of punctures, postinjection corneal sensitivity, and sensory or motor blockade duration and quality; however, restoration of conjugate eye movement occurred later in control eyes. For eyes injected with UG, mean IOP was 18.6 mm Hg, compared with 23.3 mm Hg for control eyes. Incidence of subconjunctival hemorrhage was higher for control eyes; severity of chemosis and hyperemia varied over time within both groups of eyes.
Conclusion and Clinical Relevance—In dogs, peribulbar injection of ropivacaine with UG is feasible in dogs and provides effective sensory and motor blockades similar to those achieved with conventional techniques.

Published: November 2014

Abstract
Objective—To evaluate whether the application of steam to a variety of surface types in a veterinary hospital would effectively reduce the number of bacteria.
Sample—5 surface types.
Procedures—Steam was applied as a surface treatment for disinfection to 18 test sites of 5 surface types in a veterinary hospital. A pretreatment sample was obtained by collection of a swab specimen from the left side of each defined test surface. Steam disinfection was performed on the right side of each test surface, and a posttreatment sample was then collected in the same manner from the treated (right) side of each test surface. Total bacteria for pretreatment and posttreatment samples were quantified by heterotrophic plate counts and for Staphylococcus aureus, Pseudomonas spp, and total coliforms by counts on selective media.
Results—Significant reductions were observed in heterotrophic plate counts after steam application to dog runs and dog kennel floors. A significant reduction in counts of Pseudomonas spp was observed after steam application to tub sinks. Bacterial counts were reduced, but not significantly, on most other test surfaces that had adequate pretreatment counts for quantification.
Conclusions and Clinical Relevance—Development of health-care–associated infections is of increasing concern in human and veterinary medicine. The application of steam significantly reduced bacterial numbers on a variety of surfaces within a veterinary facility. Steam disinfection may prove to be an alternative or adjunct to chemical disinfection within veterinary practices.

Abstract
Objective—To determine dose dependency of tranexamic acid–induced emesis and the time course of the antifibrinolytic potency of tranexamic acid in dogs.
Animals—10 Beagles.
Procedures—In a dose-escalating experiment, ascending doses of tranexamic acid (10, 20, and 30 mg/kg, IV) were administered at 5-minute intervals until vomiting was observed. In a separate single-dose experiment, ascending doses of tranexamic acid (20, 30, 40, and 50 mg/kg, IV) were administered at 1-week intervals until vomiting was observed. Time to onset of vomiting and number of vomiting episodes were measured in both experiments. In a coagulation experiment, a single 50 mg/kg bolus of tranexamic acid was administered, and blood was obtained 1 hour before and 20 minutes, 3 hours, and 24 hours after administration. Antifibrinolytic potency of tranexamic acid was evaluated by use of a modified rotational thromboelastography method.
Results—Tranexamic acid induced vomiting in a dose-dependent manner. Vomiting frequency was < 2 episodes, and vomiting concluded < 250 seconds after administration. Antifibrinolytic potency of tranexamic acid was significantly higher at 20 minutes following administration, but not different by 24 hours, when compared with the potency measured before administration. No adverse effects were observed in any experiment.
Conclusions and Clinical Relevance—IV administration of tranexamic acid induced emesis in a dose-dependent manner. The antifibrinolytic potency of tranexamic acid decreased in a time-dependent manner and was resolved < 24 hours after administration. Further studies are warranted to investigate the emetic and other adverse effects of tranexamic acid in dogs of various breeds and ages.
Les croix triomphales de Notre-Dame de Paris et de la cathédrale de Chartres

The Triumphal Crosses of Notre-Dame de Paris and the Cathedra ! of Chartres : an Unpublished Document, by Maryse Bideault.
The discovery at the Minutier central of the Archives nationales of two contracts negotiated in 1579 by Claude Duboys, « maistre peintre et tailleur d'imaiges », brings to light some interesting détails concerning the crucifix that surmounted the médiéval jubé of Notre-Dame de Paris ; both jubé and crucifix were destroyed in 1699 when, under the direction of Robert de Cotte, the choir was remodelled and redecorated. These contracts deal in fact with the installation on the jubé of Chartres Cathedral of an oaken crucifix « taillé et painct de mesme façon, grandeurs, mesures et estofîes » as that of Notre-Dame de Paris ; they furnish information about the iconography of the Parisian crucifix, its exact dimensions and its polychromy, and allow us to affirm that the Parisian crucifix, whose total height with its « guimberge » came to more than 8m50, was very probably in wood, as are a séries of thirteenth-century monumental crucifixes that hâve survived in Germany (Osnabrück, Halberstadt, and Wechselburg).
Enfance, école, famille. Perspectives historiques et enjeux actuels du contrôle de la fréquentation scolaire
Authors: Becquemin Michèle 
Published: November 2014

Childhood, school, family.
Historical perspectives and current issues involved in the monitoring of school attendance
Through a diachronic presentation of policies to combat parents’ failure to send their children to school, this article highlights the building and development of political and legal ties between the school, family allowances, the protection of children at risk, and the handling of juvenile delinquency. Successive definitions of problems regarding children and suggested solutions first of all bring to light republican opposition to parental authority in the name of education and child protection, followed by the building of a state-controlled socio-legal monitoring system that combines the protection of families and of children, and lastly, the fragmentation process at work in educational and social policies related to governments’ managerial and safety concerns over the past twenty years. The definition of public action therefore once again refocuses on parents through socio-administrative supervision, usually in the form of a contract, which wavers between increased accountability and social support. In looking at the reasoning that preceded recent legislative reversals, it becomes clear that controversies over the use of family allowances to sanction truancy have contributed to clouding certain issues, for instance, that of the child’s place in society.
