Electronic music scenes: A comparison of the diverging spatial contexts of the electronic dance music scenes of Berlin and Amsterdam
Authors: Dorst Hade
Published: August 2015

Music scenes are inseparable from their spatial environment, and thrive under certain spatial conditions. Urban regulations and planning play a defining role in the development of local scenes. This article examines two epicentres of the EDM scene, Berlin and Amsterdam, in order to show how factors such as availability of distinctive and affordable spaces for music production, and the regulation and planning of such spaces, impact the ways in which the EDM scene unfolds. In Berlin, the abundance of vacant spaces and lack of (enforcement of) regulations following the fall of the Berlin Wall at the end of the 1980s are key factors in the city’s consolidation as a world-renowned club scene. Stricter enforcement of regulations and a shortage of inner-city space for creative activity in Amsterdam favour a music scene of festivals and foot-loose actors, mostly promoters.

Published: August 2015

Este trabalho descreve o processo de adequação ambiental e expressa os resultados da avaliação dos compromissos com a sustentabilidade na Universidade Federal do Rio Grande (FURG), a partir da análise da linha do tempo das suas ações de gestão ambiental e do projeto “Definição de indicadores para a avaliação das políticas de sustentabilidade em Universidades Latino-americanas”, ligado à Rede de Indicadores de Sustentabilidade nas Universidades – RISU (Projeto RISU). Esse projeto é uma iniciativa da Universidad Autónoma de Madrid (UAM), do qual participam 10 países latino-americanos. No Brasil foram 13 as universidades participantes, dentre instituições de ensino superior públicas e privadas. A ferramenta de pesquisa do Projeto RISU foi aplicada na FURG, considerando a abrangência dos 114 itens a serem investigados, divididos em seis grupos: Política de Sustentabilidade; Sensibilização e Participação; Responsabilidade Socioambiental; Docência; Pesquisa e Transferência; Gestão Ambiental (sobre os temas Água, Urbanismo e Biodiversidade, Energia, Mobilidade, Resíduos, Contratação Responsável). A estratégia metodológica para a aplicação do questionário constou da coleta de dados por meio de consulta a documentos oficiais e reuniões com os responsáveis em cada uma das seis áreas no Campus Carreiros. Por meio da participação neste projeto a universidade verificou que o seu nível de comprometimento com a sustentabilidade é variável dentre as áreas analisadas, possibilitando a avaliação, o desenvolvimento, a correção e o aperfeiçoamento de políticas e ações de melhoria contínua para a instituição. Considerou-se que o Projeto RISU evidenciou de modo objetivo a situação atual da FURG, que está consolidando a sua Política Ambiental e cumprindo condicionantes de licenciamento, tendo sido uma importante ferramenta para a melhoria contínua do processo de adequação ambiental dessa instituição de ensino superior.

POLÍTICAS PÚBLICAS DE SAÚDE PARA IDOSOS COM ALZHEIMER
Authors: Barbosa Abreu Célia , Val Eduardo Manuel
Published: August 2015

Contemporaneamente, nota-se a ocorrência do envelhecimento populacional mundial, que é visto como um dos principais ganhos sociais do século XX, mas também como um fator de risco para o desenvolvimento global. Mundialmente, por conseguinte, percebe-se a imprescindibilidade de políticas públicas voltadas para os idosos. Mais do que isso, com o atual e constante crescimento da expectativa de vida da população, tem início a  preocupação relativamente ao número de pessoas afetadas por doenças relacionadas à idade, como é o caso do mal de Alzheimer, o qual deverá aumentar drasticamente nos próximos anos. Torna-se, pois, assunto da ordem do dia a discussão sobre as políticas públicas de saúde para os idosos, com foco  específico na questão da doença de Alzheimer, principal causa de demência da pessoa idosa. Neste sentido, o presente trabalho consiste numa pesquisa teórica, que se utiliza dos métodos indutivo e comparatístico.
The use of multi-criteria analysis for selection of technology for a household WWTP compatible with sustainable development / Zastosowanie analizy wielokryterialnej do wyboru rozwiązania technologicznego przydomowej oczyszczalni ścieków zgodnego z ideą zrównoważonego rozwoju

Published: August 2015

This paper presents the use of multi-criteria analysis as a tool that helps choosing an adequate technology for a household wastewater treatment plant. In the process of selection the criteria of sustainable development were taken into account. Five municipal mechanical-biological treatment plants were chosen for the comparative multi-criteria analysis. Different treatment technologies, such as sand filter, activated sludge, trickling filter, a hybrid system - activated sludge/trickling filter and a hybrid constructed wetland system VF-HF type (vertical and horizontal fl ow) were taken into account. The plants’ capacities were 1 m3∙d-1 (PE=8) and they all meet the environmental regulations. Additionally, a solution with a drainage system was included into the analysis. On the basis of multi-criteria analysis it was found that the preferred wastewater treatment technologies, consistent with the principles of sustainable development, were a sand filter and a hybrid constructed wetland type VF-HF. A drainage system was chosen as the best solution due to the economic criteria, however, taking into consideration the primary (ecological) criterion, employment of such systems on a larger scale disagree with the principles of sustainable development. It was found that activated sludge is the least favourable technology. The analysis showed that this technology is not compatible with the principles of sustainable development, due to a lack of proper technological stability and low reliability.

Authors: Sapiński Bogdan
Published: August 2015

The paper summarises the theoretical study of a magnetorheological (MR) damper operated in squeeze mode, intended to be used as an actuator in a semi-active mount system in a car motor. The structural design and operating principle of the damper are described and a simplified model of the MR fluid flow in the gap is presented. The plots of the damper force generated by the MR damper are obtained for monoharmonic piston motion with respect to the centre point of the gap height and in the conditions of the control coil being supplied with direct current.
Detection of Two-Phase Flow Patterns in a Vertical Minichannel Using the Recurrence Quantification Analysis
Authors: Mosdorf Romuald , Górski Grzegorz
Published: August 2015

The two-phase flow (water-air) occurring in square minichannel (3x3 mm) has been analysed. In the minichannel it has been observed: bubbly flow, flow of confined bubbles, flow of elongated bubbles, slug flow and semi-annular flow. The time series recorded by laser-phototransistor sensor was analysed using the recurrence quantification analysis. The two coefficients:Recurrence rate (RR) and Determinism (DET) have been used for identification of differences between the dynamics of two-phase flow patterns. The algorithm which has been used normalizes the analysed time series before calculating the recurrence plots.Therefore in analysis the quantitative signal characteristicswas neglected. Despite of the neglect of quantitative signal characteristics the analysis of its dynamics (chart of DET vs. RR) allows to identify the two-phase flow patterns. This confirms that this type of analysis can be used to identify the two-phase flow patterns in minichannels.
Antiplane Deformation of a Bimaterial Containing an Interfacial Crack with the Account of Friction I. Single Loading
Authors: Sulym Heorhiy , Piskozub Lyubov , Piskozub Yosyf , Pasternak Iaroslav
Published: August 2015

The paper presents the exact analytic solution to the antiplane problem for a non-homogeneous bimaterial medium containing closed interfacial cracks, which faces can move relatively to each other with dry friction. The medium is subjected to the action of normal and arbitrary single loading in a longitudinal direction. Based on the discontinuity function method the problem is reduced to the solution of the system of singular integral-differential equations for stress and displacement discontinuities at the possible slippage zones. Influence of loading parameters and the effects of friction on the sizes of these zones is analyzed. The stress intensity factors, stress and displacement discontinuities, energy dissipation are determined for several characteristic types of external loading.
Alternative Social States and the Basic Income Debate: Institutions, Inequality and Human Development
Authors: Haagh Louise
Published: August 2015

This essay explores how institutional responses to human development differentiate capitalist systems and shape developmental dimensions of stratification and freedom. I advocate differentiating the analyses of systems of institutions and freedom, including by setting out their developmental dimensions. Doing so allows me to analyse ethical and political problems of high inequality capitalism that Piketty highlights as they relate to the cooperative and developmental character of public services, and to set the BI project in relation to human development.

Multiscale thermodynamic analysis on hydrogen-induced intergranular cracking in an alloy steel with segregated solutes
Authors: Yamaguchi Masatake , Ebihara Ken-ichi , Itakura Mitsuhiro
Published: August 2015

A multiscale analysis has been conducted on hydrogen-induced intergranular cracking at ambient temperature in medium strength (840 MPa) Ni-Cr steel with antimony, tin, and phosphorous segregation. Combining first-principles calculations and fracture mechanics experiments, a multiscale relationship between threshold stress intensity factor (K
th) and cohesive energy of grain boundary (the ideal work of interfacial separation, 2γ
int) was revealed. The K
th was found to decrease rapidly under a certain threshold of 2γ
int, where the 2γ
int decreases mainly by mobile hydrogen segregation on fracture surfaces. This segregation is considered to arise during formation of the fracture surfaces under thermodynamic equilibrium in slow crack growth. The resulting strong decohesion probably makes it difficult to emit dislocations at the microcrack tip region, leading to a large reduction in stress intensity factor. Our analysis based on this mobile hydrogen decohesion demonstrates that the K
th decreases dramatically within a low and narrow range of hydrogen content in iron lattice in high-strength steels.
Energy dissipation of a two-relaxation-time material
Authors: Xu Tao-Tao
Published: August 2015

Energy dissipation in polymeric materials was studied using a two-relaxation-time model. A differential form of a constitutive relation was constructed with the viscoelasticity theory. Through the simulation of a cyclic loading and unloading test, the dependence of the dissipated energy on the model parameters and external loading variables was determined and analyzed. In particular, the characteristics of the hysteresis phenomenon of a material with more than one relaxation time were studied in detail.
Modely výškových kriviek jedľovo-bukových porastov Východných Karpát / Models of height curves in fir-beech stands of the Eastern Carpathians
Authors: Klouček Tomáš , Štefančík Igor , Petráš Rudolf , Mecko Julian , Slávik Martin
Published: August 2015

The models of height curves were derived from repeated measurements at six permanent research plots in the experimental object of Komárnik situated in the Eastern Carpathians. During more than 50 years of investigation, the heights of 1,346 beech and 1,208 fir trees were measured. Tree heights had a great variability, but the stage-shift of height curves was not confirmed. The non-linear regression models of height curves for beech and fir were derived, where tree height is a function of tree diameter and model height for a selected diameter class. They are based on the Korf growth curve with three parameters. The models explained 90% and 94% of beech and fir height variability, respectively. The models confirmed the actual knowledge that fir had higher tree height increment than beech especially for trees with greater diameters. The comparison of our models to those developed by other authors showed that the shape of height curves slightly differed. Beech curve was characterised by greater, while fir curve by lesser curvature in comparison with other published models. Our models have only local validity due to the limited scope of experimental data. They can be applied under the local conditions in order to perform valuation and simulation of growing stock development and increments of uneven-aged and multistoried fir-beech stands.
Finite Product of Semiring of Sets
Authors: Coghetto Roland
Published: August 2015

We formalize that the image of a semiring of sets [17] by an injective function is a semiring of sets.We offer a non-trivial example of a semiring of sets in a topological space [21]. Finally, we show that the finite product of a semiring of sets is also a semiring of sets [21] and that the finite product of a classical semiring of sets [8] is a classical semiring of sets. In this case, we use here the notation from the book of Aliprantis and Border [1].
Effect of heavy metals on soil nematode communities in the vicinity of a metallurgical plant in North Slovakia

Published: August 2015

The effect of industrial pollution from chromium ferroalloys production on soil free-living nematode assemblages, c-p groups and generic composition was investigated along 7-km transect. From trace elements (Cr, Cu, Ni and Pb), only chromium exceeded the thresholds for uncontaminated soils (10 mg.kg-1) near the pollution source. In contrast mobilizable fraction of Cr has increased with the distance from the pollution source and was found to be positively correlated with Cox, soil pH, and moisture. Generic richness (nematode diversity) was also higher at remote sites. The low contamination has no significant impact on the nematode communities as illustrated by the c-p groups composition and balanced community structure. Widely applied ecological indices SI and EI also proved maturing ecosystem without any significant stress responses
Aufruhr! Zur epochenübergreifenden Beschreibung beschleunigten sozialen Wandels in Krisenzeiten
Authors: Kohl Thomas
Published: August 2015

Wie lässt sich das Verhältnis von kurzfristiger sozialer Unruhe zu langfristigen Veränderungen für die historisch arbeitenden Wissenschaften bestimmen? Der Beitrag löst mit Hilfe des Begriffs „Aufruhr“ die Analyserichtung historischen sozialen Wandels von zielgerichteten Schemata, wie z. B. Revolution, und betont demgegenüber die Eigenlogik von Verlaufsformen. Im Deutschen und in anderen Sprachen enthält das Wort „Aufruhr“ sowohl ein Wert- als auch ein Zeiturteil; es impliziert, dass eine Handlungsweise illegitim oder illegal ist. So verstanden, dient „Aufruhr“ in den Geschichts- und Sozialwissenschaften außerdem primär zur Kennzeichnung vormoderner Phänomene. Diese Konvention (re)produziert die Überzeugung von einer Alterität der Vormoderne und verstärkt zugleich die Orientierung an hergebrachten Epochengrenzen. Demgegenüber wird mit der Entwicklung des Begriffs „Aufruhr“ der Versuch unternommen, Phänomene zunächst unabhängig von epochenspezifischen Großdeutungen zu interpretieren. Dazu stellt der Artikel drei historische Beispiele von Aufruhr aus verschiedenen Epochen vor: Auf zwei Unruhen in städtischen Kontexten des hohen und späten Mittelalters folgt ein Fall aus dem industriellen Ruhrgebiet der 1920er Jahre. Auf dieser Basis erarbeitet er als heuristisches Instrumentarium fünf analytisch getrennte Merkmale von Aufruhr: Gruppencharakter und Gesellschaftsbezug, Öffentlichkeit, Gewalt, Verdichtung von Raum und Zeit sowie Komplexität und Kontingenz. Diese Eigenschaften bleiben zwar an zeitliche und räumliche Spezifika gebunden, sie gestatten aber einen vergleichenden Blick auf Aufruhr als ubiquitäres Phänomen von Gesellschaften über Zeiten und Räume hinweg. Aufruhr macht so im doppelten Sinne Geschichte, als Ereignis und als Generator für Fragen an die Vergangenheit.
Wahrheit im Dschungel von Literatur, Wissenschaft und Politik. Upton Sinclairs „The Jungle“ und die Reform der Lebensmittelkontrolle in den USA der „Progressive Era“
Authors: Graf Rüdiger
Published: August 2015

Upton Sinclairs Roman „The Jungle“ (1906) über das Schicksal der Arbeiter und die hygienischen Zustände in den Schlachthöfen von Chicago wird oft für die Verschärfung der Lebensmittelkontrolle in den USA in der Progressive Era verantwortlich gemacht. Der Aufsatz fragt genauer danach, welche Rolle das Wissen über die Schlachthöfe für den Meat Inspection Act, aber auch den oft in einem Atemzug genannten Pure Food and Drugs Act spielte bzw. überhaupt spielen konnte. Im sich entfaltenden Skandal und in den Beratungen des Kongresses beanspruchten neben Sinclair auch andere Akteure mit unterschiedlicher Autorität und verschiedenen diskursiven Ressourcen, die Zustände in den Schlachthöfen zu kennen. Die Wahrheit über die sogenannten „packing houses“ wurde literarisch oder journalistisch enthüllt, mit wissenschaftlicher Autorität festgestellt, mit juristischen Argumenten begründet oder in Zweifel gezogen. Behauptungen stützten sich auf die eigene Anschauung, wissenschaftliche Experten oder auf das Urteil vertrauenswürdiger Personen. Ganz explizit wurden in diesen Debatten Wahrheitsansprüche bzw. die Bedeutung von Wissen für die Politikgestaltung verhandelt. Wie wurde jeweils versucht, die Wahrheitsansprüche einzulösen? Wem gelang es, sie von einem Diskurszusammenhang in den anderen zu übersetzen? Und welche Bedeutung hatten das Wissen über die Schlachthöfe für die Ausgestaltung der Lebensmittelkontrolle und die Wiederherstellung des Vertrauens in die Qualität der Nahrungsmittelversorgung und vor allem Fleischproduktion? Nach einem Überblick über die Veränderung des Wissens um die Qualität von Nahrungs- und Arzneimitteln sowie vor allem Fleischprodukten im Verlauf des 19. Jahrhunderts sollen diese Fragen durch eine Untersuchung der Debatten um „The Jungle“ und die Gesetzgebungsprozesse des Jahres 1906 geklärt werden. Diese Analyse der Wahrheitskommunikation und Wissensproduktion eröffnet so Einblicke in das Verhältnis von Wissen und Politik bzw. von visueller Evidenz, Expertenwissen und Vertrauen in der Nahrungsmittelproduktion um 1900 und darüber hinaus.
Characteristics of Honey Bee (Apis Mellifera Carnica, Pollman 1879) Queens Reared in Slovenian Commercial Breeding Stations
Authors: Gregorc Aleš , Smodiš Škerl Maja I.
Published: August 2015

In this three-year-trial study, we examined the quality of mated queens based on morphological and physiology traits. At each location, sister queen bees were reared each year from one Apis mellifera carnica breeder queen. Queens were also reared and mated in different locations. Altogether, we sampled and analysed 324 queens from 27 apiaries in 2006, 288 queens from 24 apiaries in 2008, and 276 queens from 23 apiaries in 2010. Nine queens from each apiary were sampled and dissected for morphological analyses and Nosema ceranae (N. ceranae) spores, if present, were quantified. Three queens from each apiary were prepared and tested for four viruses: acute bee paralysis virus (ABPV), black queen cell virus (BQCV), deformed wing virus (DWV), and sacbrood virus (SBV). The highest average queen weight of 209.49 ± 9.82 mg was detected in 2008. The highest average ovary weight of 78.67 ± 11.86 mg was detected in 2010, and the highest number of ovarioles was 161.59 ± 8.70 in 2006. The average number of spermatozoa in queens ranged from 3.30 x 106 in 2006 to 5.23 x 106 in 2010. Nosema ceranae spores were found in queens sampled in 2008 and 2010. Viruses were discovered sporadically during the queen testing periods from 2006 - 2010. This study importantly demonstrates that queens from rearing stations require regular evaluation for morphological and physiological changes as well as for infection from harmful pathogens. These results could also be used in establishing relevant commercial standards for rearing quality queens.
Parties, persons, and one-at-a-time: conversation analysis and ELF
Authors: Santner-Wolfartsberger Anita
Published: August 2015

Drawing on an analysis of ELF data, this article deals with the characteristics and complexities of turn-taking in interactions involving three or more participants. Sacks et al.’s (1974) often quoted framework for turn-taking in conversations, which can still be regarded canonical reading in the conversation analytic literature, serves as a starting point for this investigation. The aim of this paper is to scrutinize the applicability of the turn-taking model for group interactions. A key concept in this regard is the notion of aparty: the conversation analytic model for turn-taking posits that turn-taking does not take place between individual speakers, but between parties (hence the termmulti-party conversation) which can potentially consist of several speakers (cf. Schegloff 1995: 32–33). In group interactions it is thus possible that overlap occurs among co-incumbents of the same party. This kind of simultaneous speech, however, has not yet been subject of systematic empirical analysis. The present paper offers a preliminary account of this aspect of turn-taking in multi-participant interaction by discussing data extracts from an ELF workplace meeting of seven speakers and suggests possible avenues for further research on the phenomenon.

Published: August 2015

The Ligurian leafhopper (Eupteryx decemnotata Rey 1891) has been recorded for the first time in Poland, in a commercial greenhouse in Warsaw. Individuals were collected from rosemary (Rosmarinus officinalis L.). Intense feeding of this species caused serious damage in the cultivation of rosemary. For this reason, the range extension of this species must be monitored.

Apparent filler–gap mismatches in Welsh
Authors: Borsley Robert D.
Published: August 2015

Filler–gap dependencies involving a clause-initial filler constituent of some kind followed by a matching gap are an important feature of human languages. There are also certain cases where what looks like a filler differs in some way from the following gap. In the case of Welsh there is a mismatch between apparent filler and gap in some nominal cleft sentences. It can be argued, however, that the initial constituent is not a filler but one term of a hidden identity predication. There are various other complexities in this area. There is one word, the identity copula, which only allows a complement that is a gap. There are two cases where a deletion process conceals the identity of the initial constituent in a cleft sentence, making a Progressive Phrase look like a Verb Phrase and a Predicative Phrase look like an Adjective Phrase or a Noun Phrase. Finally, there are three cases where a verb with a gap as a dependent has a special form, two cases involving the predicational copula and one involving all transitive verbs. Thus, a number of mechanisms are required to deal with the full set of facts.
Fabrication of cellulose fine fiber based membranes embedded with silver nanoparticles via Forcespinning
Authors: Xu Fenghua , Weng Baicheng , Materon Luis A. , Kuang Anxiu , Trujillo Jorge A. , Lozano Karen
Published: August 2015

This study presents the successful development of cellulose fiber based membranes embedded with silver nanoparticles. These fine fiber membranes were developed utilizing the Forcespinning (FS) technique followed by alkaline hydrolysis treatment. The fiber morphology, homogeneity and yield were optimized by varying spinning parameters such as polymer concentration and angular velocity of the spinnerets. The structure, thermal and mechanical properties, and water absorption capability of the developed membranes were investigated. The cellulose acetate (CA) present in the membrane was converted to cellulose in the presence of embedded silver nanoparticles by alkaline hydrolysis. The silver nanoparticles embedded cellulose membrane exhibits outstanding water absorption capacity with fast uptake rate. Its high porosity, three-dimensional network structure with well-interconnected pores, as well as the intrinsically highly hydrophilic nature of cellulose material greatly favor its potential application as wound dressings. The antimicrobial activity was evaluated by the disk diffusion method. The composite membranes exhibit excellent antimicrobial activity against Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa, and Gram-positive Staphylococcus aureus, owing to the slow and sustained release of embedded silver nanoparticles.
The restricted isometry property for random matrices with ϕ-subgaussian entries
Authors: Kozachenko Yuriy , Troshki Viktor
Published: August 2015

The aim of this article is to construct the generalized random matrices, which satisfies the restricted isometry property (as introduced by Candes and Tao). Let the data be presented as a product of a vector with not more than K nonzero coordinates by a given matrix. We show that for such data we can change the upper bound of the variable K. In particular, we prove that the random matrices whose entries are independent realizations of random variables from ϕ-subgaussian space could be used in the theory of compressive sensing for encoding vectors.

Streszczenie

Badano wpływ zanieczyszczenia gleby niklem (0, 75, 150 i 225 mg Ni kg-1 gleby) na tle zróżnicowanego wapnowania (0 Ca i Ca w g 1 Hh) i materiałów organicznych (bez stosowania materiałów organicznych, słoma żytnia i węgiel brunatny z Kopalni Węgla Brunatnego Turów) na zawartość niklu w kupkówce pospolitej i frakcje tego metalu w glebie. Analizowano cztery pokosy kupkówki pospolitej zebrane w trzecim roku doświadczenia wazonowego oraz oznaczono frakcje niklu w glebie pobranej po ostatnim pokosie rośliny testowej. Zawartość niklu w roślinie oraz ogólną zawartość tego pierwiastka w glebie oznaczono metodą ICP-AES po wcześniejszej mineralizacji. Frakcje niklu w glebie oznaczono metodą frakcjonowania sekwencyjnego - BCR. Wprowadzenie do gleby niklu, niezależnie od ilości, spowodowało istotne zwiększenie jego zawartości w biomasie kupkówki pospolitej oraz w glebie we wszystkich frakcjach, przede wszystkim we frakcji wymiennej (F1). Wapnowanie gleby oraz aplikacja materiałów organicznych zmniejszyły zawartość niklu w biomasie kupkówki pospolitej oraz w glebie we frakcji wymiennej, bezpośrednio przyswajalnej przez rośliny, powodując jednocześnie zwiększenie jego udziału we frakcji rezydualnej (wapnowanie) oraz redukowalnej i utlenialnej (aplikacja materiałów organicznych).
Schließen auf Verbklassen
Authors: Richter Michael
Published: August 2015

Based on the fact that verb learning is a difficult issue in language acquisition, the paper non-empirically addresses the question which inference rules which type of language learner might use in order to infer verb classes from the nominal fillers in the argument positions of verbs. Probabilistic rules based on Bayesian networks allow to decide whether a verb belongs to a class or not. The complexity of the rules might give an explanation why learning the semantics of verbs is difficult and is mastered completely at late stages of the language acquisition process.
Variablenbindung und semantische Genuskongruenz bei Personalpronomen im Deutschen
Authors: Czech Henning
Published: August 2015

The gender specification of personal pronouns in German which refer to lexical hybrids like Mädchen (neuter noun; eng.: girl) can either be determined directly by the grammatical features of these nouns (das Mädchen […] es) or by the sex of their referents (das Mädchen […] sie). This phenomenon is a typical example of the alternation of grammatical and semantic agreement, which can be observed in many variations among the world’s languages. In order to explain the distribution of these two agreement types, many authors argue that there is a positive correlation of the linear and/or structural distance between the agreeing elements (controller and target) on the one hand and the acceptability of semantic agreement on the other hand. Based on empirical data, I argue for the additional integration of semantic factors which are strongly related to structural aspects. It is shown that the choice of agreement type for German personal pronouns depends on the interpretation of these words as bound or free variables, whereby semantic agreement is less likely with bound variables.

Pathological Intoxication and Alcohol Idiosyncratic Intoxication—Part I: Diagnostic and Clinical Aspects
Authors: Perr IN
Published: August 2015

The concept of pathological intoxication and its successor term, alcohol idiosyncratic reaction, has been one of ambiguity and professional disagreement. The history of such an entity reveals contradictions and varying usage—particularly in regard to the amount of alcohol required. Some feel that the current classification system is broad enough to include such reactions without the use of such terms. Laboratory and electroencephalographic findings are not diagnostic. The author suggests that if the concept is to be retained, psychiatrists utilize where possible the term “alcohol idiosyncratic reaction” in accord with Diagnostic and Statistical Manual of Mental Disorders (DSM) III guidelines, particularly in view of the medicolegal implications discussed in Part II, which follows as a separate paper.
Morphological Analysis of Opal Phytoliths for Soil Discrimination in Forensic Science Investigation
Authors: Marumo Y , Yanai H
Published: August 2015

A morphological analysis of opal phytoliths in soils was applied to forensic science soil discrimination. To examine a variation of opal phytolith composition with a difference of land use or topography, a region was chosen in a range of 5 km covering from diluvial plateau to alluvial plain. Opal phytolith compositions in soil samples collected from the same site were similar. On the other hand, there were obvious differences in the compositions between soils from different sites. In the region examined, contents of Chloridoid, Bambusoid, Fan-shape, and Elongate classes varied with sampling sites allowing us to discriminate the samples from different sites. Festucoid and Point-shape class were small in the amounts to be compared for the soil discrimination. Morphological analysis of opal phytoliths was effective to discriminate soil samples that came from different land use, even though they were indistinguishable by their mineralogical characteristics. About 2 mg of opal phytolith fraction, 10 to 200 µm in diameter, less than 2.3 in specific gravity, was a sufficient amount for the morphological analysis.

Despite the fact that many bite marks do not show “depth,” demonstration of the presence of this third dimension can produce significant data for evidentiary purposes. In some instances, these data may transform what seem to be class characteristics of a bite mark into individual characteristics and thus impart much more uniqueness to the evidence. Because of the high level of resolution and magnification of SEM, some three-dimensional characteristics not visible to the eye can be shown quite clearly by its use. Emphasis will be given to the value of SEM as a tool of the forensic odontologist in bite mark analysis.

Published: August 2015

A case is presented of sudden death during physical activity in a 15-year-old boy with clinically inactive mucocutaneous lymph node syndrome (Kawasaki disease). At autopsy, the coronary arteries were involved by multiple aneurysms and obstructive thrombi, and the left ventricular myocardium was extensively scarred. Although Kawasaki disease most commonly occurs in infants and young children, it may be a cause of sudden death in adolescents.
Effect of Garment Cleaning on the Recovery and Redistribution of Transferred Fibers
Authors: Robertson J , Olaniyan D
Published: August 2015

In an attempt to remove incriminating evidence, a criminal may wash or dry-clean articles of clothing worn during the commission of a crime. This would be expected to remove contact trace material that might be present. In this study, articles of clothing were subjected to hand washing, machine washing, and dry cleaning following the transfer of fibers to them under simulated contact conditions. All three methods resulted in fiber loss, but the percentage of transferred fibers remaining varied from over 70% for any acrylic garment to less than 5% for a nylon garment, reflecting the persistence properties of these fabrics. In general, machine washing resulted in the poorest recovery of fibers. In all cases very few fibers in excess of 0.5 cm were recovered and there was some evidence of fragmentation of longer fibers. Fibers were also moved or redistributed away from the area of contact during cleaning.

Published: August 2015

Concepts of the decision-making process in mass casualty identification are discussed. The importance of the correct data type, the correct data format, and the appropriate decision paths are emphasized. Also discussed are the hidden dangers in the use of changeable physical characteristics for sorting factors. A suggested decision process for use in postmortem identification is outlined, along with its application to computer-assisted identifications.

Authors: Prichard JG , Kossoris PD , Leibovitch RA , Robertson LD , Lovell FW
Published: August 2015

Bites of Trombiculid mites implicated a suspect during a homicide investigation. Clinical documentation of the bites, correlation with entomological studies, and submission of evidence at trial are reported. Insects that have a discrete geographic distribution and leave bites of a characteristic nature may have important forensic science implications.
A Double Origin Electrophoretic Method for the Simultaneous Separation of Adenosine Deaminase, Adenylate Kinase, and Carbonic Anhydrase II
Authors: Murch RS , Gambel AM , Kearney JJ
Published: August 2015

A rapid, reliable method for the simultaneous separation of adenosine deaminase, adenylate kinase, and carbonic anhydrase II by agarose gel electrophoresis is presented. This method uses a double origin sample application system. Unreduced sample extracts for adenylate kinase analysis are applied 13.0 cm from the anode. Reduced sample extracts for the remaining proteins of interest are applied 7.0 cm from the anode. The use of applicator foils and an increased voltage gradient result in superior resolution, linearity, and band sharpness of the allozyme patterns. Further, there is no masking of the adenylate kinase 2 band as a result of the use of a reducing agent, and carbonic anhydrase II is resolved without interference from hemoglobin as has been observed with other multisystem methods.

Authors: Wraxall BGD , Stolorow MD
Published: August 2015

A procedure for the multisystem analysis of bloodstains using the simultaneous separation of the enzymes glyoxalase I, esterase D, and phosphoglucomutase has been developed. The amount of bloodstain required has therefore been reduced threefold without any loss in resolution and sensitivity. Bloodstains at least seven weeks old have been correctly phenotyped in all three systems.

The patient expired suddenly as a result of rupture of the subcapsular hematoma of the liver causing massive intraperitoneal hemorrhage. The pathophysiology and complications of the fatty liver of pregnancy are discussed.
Improved Enhancement of Ninhydrin Developed Fingerprints by Cadmium Complexation Using Low Temperature Photoluminescence Techniques
Authors: Stoilovic M , Kobus HJ , Margot PAJ-L , Warrener RN
Published: August 2015

Fingerprints developed with ninhydrin form stable, colored complexes when treated with various metal salts. Many of these colored complexes can be used to increase the sensitivity of detection of latent prints because of photoluminescent properties. The intensity of this photoluminescence is increased at low temperature (77K), and this is a common characteristic of each of the complexes formed with salts of the IIb group of the Periodic Table. Spectral characteristics of these Group IIb metal complexes and the influence of environmental factors on their formation are reported. These data have helped determine optimal conditions for the enhancement of ninhydrin developed fingerprints. Taking into account spectral characteristics, solubility, versatility, stability, and reproducibility, the use of the cadmium nitrate tetrahydrate complex is advocated for general use for fingerprint enhancement. The use of zinc nitrate is favored if toxicological considerations are paramount, but ninhydrin development has to be carefully controlled if optimal results are to be obtained. Limited applications for mercuric complexes are found when a red shift is desired to remove background effects.
Pharmaceutical Error Resulting in Fatal Diabetic Ketoacidosis

Published: August 2015

A 41-year-old male with a 25-year history of diabetes mellitus requiring 25 to 30 units of neutral protamine hagedorn (NPH) insulin daily was found dead at home. Recent history revealed that he was well until the last four days of life when he had the onset of nausea, vomiting, and anorexia coinciding with procurement of a new bottle of insulin from his pharmacist. Pertinent autopsy findings included coronary and aortic atherosclerosis, a peptic ulcer, and diabetic glomerulopathy. Chemical analysis of the vitreous humor, including glucose (813 mg/dL) and acetone (40 mg/dL), revealed that he died of diabetic ketoacidosis. Further investigation revealed that the pharmacist had accidentally substituted regular insulin, with a duration of action of up to 6 h as opposed to 24 to 28 h, for NPH. Cultures of blood and of the regular insulin yielded no growth. Analysis of this case emphasizes the importance of obtaining a careful medical and medication history and the usefulness of vitreous electrolytes when investigating a sudden death in a diabetic.
Some Parameters Affecting the Quality of ESDA Results
Authors: Riebeling IJ , Kobus HJ
Published: August 2015

A systematic evaluation of the effect of humidity on ESDA images was made. The results showed that the quality of the ESDA images developed depends not upon the water content of the paper at the time the indentations are made, but rather on changes in the water content, which may occur during the period between the indentations being made and the paper being examined using the ESDA.

In order to study the effect of the moisture content on the quality of the image produced by the ESDA it was necessary to devise a system for producing standard impressions. This process has now found application as a quality control procedure for ESDA examination.

Authors: Karhunen PJ , Brummer-Korvenkontio H , Leinikki P , Nyberg M
Published: August 2015

The stability of human immunodeficiency virus (HIV) antibodies was studied for samples of sera, vitreous fluid and bile obtained from eight HIV-positive autopsy cases. The autopsy delay was on average 5 days. The samples were stored at room temperature (20°C) for 51 to 314 days and tested repeatedly. In Western blotting on fresh postmortem samples, the antibodies detected most of the proteins of the virus. Antibodies against all major envelope, core and transmembrane proteins, although weakened, were also detected in stored sera. In stored vitreous fluid and bile the envelope protein gp 160, the transmembrane protein gp 41 and in half of the cases also the major core protein p 24 could still be detected. The disappearance of p 24 was associated with AIDS, but was detected in all samples from patients with early infection. Of screening tests, the enzyme-linked immunosorbent assay applying synthetic peptide as an antigen detected antibodies from all serum samples, but was less applicable to vitreous fluid or bile. Another immunoassay, applying recombinant antigen, succeeded in vitreous fluid and bile but not in sera. The rapid visually read assay detected antibodies in most samples of fresh whole blood, bile and in most of the vitreous samples, but was less useful on stored specimens.
Firearm Suicides During Confrontations with Police

We reviewed the case records of suicides in Marion County, Indiana (Indianapolis) and in surrounding counties from 1984 through 1992. Out of 1203 suicides, there were 14 in which armed, on-duty police officers were confronting, pursuing, or apprehending the subject of the death investigation. All subjects were male, and the peak age range was 30 to 34 years. The head, especially the right temple, was the usual site of the fatal wound. More than half of the incidents started as domestic disputes with a wife or girlfriend. Many of the others occurred when police officers pursued or arrested a suspect wanted for a previous felony. Ethanol was involved in less than half of the cases, and drugs were not a factor. In at least four cases, the presence of police was a factor that precipitated the suicide. The histories of the 14 cases demonstrate the potential for controversy and the challenges for forensic scientists investigating suicides during police confrontations.
Reanalysis of Forensic Urine Specimens Containing Benzoylecgonine and THC-COOH
Authors: Romberg RW , Past MR
Published: August 2015

Drug testing laboratories are often requested to retest specimens that have tested positive. The reproducibility of analytical retest data for delta-9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH) and benzoylecgonine in specimens that had previously been analyzed and then frozen by the Navy Drug Screening Laboratory, Great Lakes is examined in this study.

All specimens were tested by gas chromatography/mass spectrometry (GC/MS). Retest values generally showed a decrease in concentration but exhibited considerable variability. Eighty-five THC-COOH positive urine specimens stored frozen for 1 to 10 months (average 2.3 months) declined an average of 25% (range, +30% to −80%) and 61 benzoylecgonine positive urine specimens stored for 1 to 8 months (average 2.3 months) declined an average of 19% (ranged +20% to −100%) from initial GC/MS test results.

Drugs were found to partition into strata when frozen in urine because of the thermodynamics of the freezing process. To assure a homogenous solution for repeat testing, specimens that have been frozen and thawed were gently mixed before analysis.
