Patient turnover and the relationship between nurse staffing and patient outcomes
Authors: Park Shin Hye , Blegen Mary A. , Spetz Joanne , Chapman Susan A. , De Groot Holly 
Published: March 2012

AbstractHigh patient turnover (patient throughput generated by admissions, discharges, and transfers) contributes to increased demands and resources for care. We examined how the relationship between registered nurse (RN) staffing and failure‐to‐rescue (FTR) varied with patient turnover levels by analyzing quarterly data from the University HealthSystem Consortium. The data included 42 hospitals, representing 759 nursing units and about 1 million inpatients. Higher RN staffing was associated with lower FTR. When patient turnover increased from 48.6% to 60.7% on nonintensive units (non‐ICUs), the beneficial effect of non‐ICU RN staffing on FTR was reduced by 11.5%. RN staffing should be adjusted according to patient turnover because turnover increases patient care demand beyond that presented by patient count, and outcomes may be adversely affected. © 2012 Wiley Periodicals, Inc.

AbstractBackgroundWilms tumor (WT) has a survival rate of 90% following multimodality therapy. Nevertheless, there are some groups of patients with event‐free survival rates less than 75%. In addition to clinical prognostic factors, loss of heterozygosity at 1p and/or 16q has been used to determine treatment intensity. However, the incidence of this abnormality is low, and new biomarkers are still needed.ProcedureWe analyzed methylation status of three tumor suppressor genes; Ras‐association domain family 1 protein, isoform A (RASSF1A), DCR2, and CASP8, in 84 WTs using conventional methylation‐specific PCR (cMSP), and the results were correlated with outcome. Furthermore, we analyzed the methylation status of RASSF1A by quantitative MSP (qMSP) in 171 WTs, and evaluated clinical and genetic differences between the methylated and unmethylated tumors.ResultsRASSF1A was the most frequently methylated gene identified by cMSP, and associated with a poor outcome. Patients with a RASSF1A‐methylated tumor had shorter overall and event‐free survival periods (P = 0.043 and 0.018, respectively), when a cut‐off value of 7% by qMSP was used. The methylation was more frequent in tumors of older children than younger children (P < 0.001), and in advanced‐stage tumors than early stage tumors (P = 0.001). However, multivariate analysis could not confirm the prognostic significance of RASSF1A methylation, possibly because of a small number of advanced stage tumors examined. RASSF1A methylation was correlated with LOH at 1p and/or 16q (P = 0.017), but not with WT1 abnormality, suggesting the methylation and LOH to involve the same tumorigenic pathway.ConclusionsThe methylation status of RASSF1A might be a novel biomarker to predict outcome of WT patients.

Physical aging and thermal aging resistance of polycarbonate/poly(styrene‐b‐(ethylene‐co‐butylene)‐b‐styrene) blends
Authors: Suzuki Shuta , Nishitsuji Shotaro , Inoue Takashi 
Published: March 2012

AbstractThe effect of thermal annealing on the mechanical properties of polycarbonate (PC) was investigated by tensile testing, Izod impact testing, and differential scanning calorimetry (DSC). An endothermic peak appeared in the DSC curve by annealing at various temperatures below Tg. The peak area, as a measure of the degree of physical aging, increased with annealing time. The Izod impact strength decreased suddenly just before an endothermic peak became detectable. The results imply that at the very early stage of physical aging, a trigger for the ductile‐to‐brittle transition may be initiated. By blending hydrogenated styrene‐butadiene‐styrene block copolymer (SEBS), the embrittlement by annealing was prevented. That is, in the PC/SEBS blends, the physical aging of PC matrix proceeded in the same way as in neat PC; however, the Izod impact strength did not decrease. This thermal aging resistance seems to originate from the negative pressure effect of SEBS particles that provides dilational stress fields for PC matrix to enhance the local segment motions. POLYM.

Published: March 2012

AbstractLaser melt electrospinning is a novel technology to produce micro/nanofibers. This solvent‐free process is more suitable for biomedical applications. In this work, the electrospun poly(L‐lactide) (PLLA) fibers with diameters ranging from 2 to 7 μm were prepared by this method, and four influencing factors of melt flow rate (MFR), laser current, collector distance, and applied voltage were investigated on the PLLA fiber diameters and its standard deviation (SD) with an orthogonal design method. The results of range analysis showed the order of significance levels as follows: applied voltage, laser current, collector distance, and MFR for fiber diameter. The SD of fiber diameter can be listed in the following order: applied voltage, MFR, laser current, and collector distance. POLYM. ENG. SCI., 52:1964–1967, 2012. © 2012 Society of Plastics Engineers
Positron annihilation lifetime spectroscopy and diffusion studies of large molecule penetrants into a polyester
Authors: Ward Shelia A. , Pethrick Richard A. 
Published: March 2012

AbstractPositron annihilation lifetime spectroscopy measurements are reported for a polyester and free volume characteristics determined as a function of temperature. The glass‐rubber transition was determined using DMTA. The diffusion behaviour of a series of large molecules; dioctyl phthalate, 2‐ethyl hexylbenzyl phthalate, nonyl phenol ethoxylate, isopropyl myristate, and oleic acid into the polyester were investigated using gravimetric measurements. The permeation does not follow simple Fickian type behaviour and the rate of diffusion of 2‐ethyl hexylbenzyl phthalate is surprisingly high in comparison to the other systems studied. At or above the Tg, the diffusion rates for all the systems studied increase substantially. The sizes of the permeant molecules in their lowest energy conformation were calculated theoretically. Comparison of the size of the molecules and that of the void size measured by positron annihilation lifetime spectroscopy measurements divides the molecules into two groups. Isopropylmyristate and oleic acid exhibits cross sections which would allow the molecules to slither into cavities. The remaining molecules have cross sections which are larger than the available void size and must swell the matrix before diffusion can occur. The permeation behaviour is influenced by the available free volume but dominated by the solubility characteristics of the permeants. POLYM. ENG.

Design and fabrication of preshaped ionic polymer metal composite gripper by thermal treatment process
Authors: Kim Dong‐Ik , Seo Beom‐Ho , Lee Seung‐Ki , Park Jae‐Hyoung 
Published: March 2012

AbstractThis article proposes a new method to fabricate the ionic polymer metal composite (IPMC) actuator with a preshaped form by a simple thermal treatment process. The effects of the thermal treatment process on the properties of the actuator such as stiffness, displacement, resonance, and generating force are analyzed. To verify the effect of the thermal treatment process on the generation force of the actuator, the four‐fingered gripper using the proposed method is designed, fabricated, and compared with an unheated actuator. Experimental results show that thermally treated IPMC actuators have an improved generatingforce compared with that of unheated actuators. POLYM. ENG.

A component model for welded beam‐to‐column joints with beams of unequal depth
Authors: Simões da Silva Luis , Jordão Sandra , Simões Rui 
Published: March 2012

AbstractIn many practical situations, internal nodes connect beams with unequal depth whenever the span lengths are not uniform. Following the methodology defined in EC 3‐1‐8, this paper presents a component model that is able to reproduce accurately the complex behavior of welded beam‐to‐column joints with beams of unequal height, which corresponds to a node configuration that is not yet covered in the EC 3 design rules. Based on an experimental program carried out at the University of Coimbra, the relevant components for the column web panel under a non‐uniform stress state are characterized, leading to the development of a new design procedure that extends the scope of EC 3‐1‐8.Ein Komponenten‐Modell für geschweißte Träger‐Stützen‐Verbindungen mit Trägern ungleicher Höhe. In vielen praktischen Situationen verbinden bei unterschiedlichen Spannweiten innere Knoten Träger ungleicher Höhe. Entsprechend der in EC 3‐1‐8 festgelegten Methodik stellt dieser Aufsatz ein Komponentenmodell für eine genaue Nachbildung des komplexen Verhaltens geschweißter Träger‐Stützen‐Verbindungen mit Trägern ungleicher Höhe vor, was einer Knotenkonfiguration entspricht, die durch die EC 3‐Bemessungsregeln noch nicht abgedeckt ist. Auf Grundlage umfangreicher Versuchsserien an der Universität von Coimbra werden die Komponenten für die Stützenstege unter ungleichmäßiger Belastung modelliert, was zur Formulierung eines neuen Bemessungsverfahrens führt, das den Umfang der im EC 3‐1‐8 dargestellten Möglichkeiten signifikant erweitert.
Francis Sibson (1814–1876): The Unsung Hero of Modern Surgery and Anesthesia
Authors: Osiro Stephen , Downs Erin , Grater Joanna , Loukas Marios 
Published: March 2012

AbstractFrancis Sibson (1814–1876) was a British physician and anatomist widely regarded as a true pioneer of the medical profession. He overcame a tragic and difficult childhood to become an avid educator at several medical schools and dedicated his life to research. For modern scientists, he is most remembered for describing Sibson’s fascia, his experimental use of curare in the treatment of hydrophobia and tetanus, and his detailed description of the positions and movements of internal organs. He died on September 7, 1876 at the age of 62 from complications of an aortic aneurysm.

In the present study, we investigated the hydrothermal treatment of titanium with divalent cation solutions and its effect in promoting the adhesion of gingival epithelial cells and fibroblasts in vitro. Gingival keratinocyte-like Sa3 cells or fibroblastic NIH3T3 cells were cultured for 1 h on experimental titanium plates hydrothermally-treated with CaCl2 (Ca) or MgCl2 (Mg) solution, or distilled water (DW). The number and adhesive strengths of attached cells on the substrata were then analyzed. The number of Sa3 cells adhering to the Ca- and Mg-treated plates was significantly larger than in the DW group, but the strength of this adhesion did not differ significantly between groups. In contrast, NIH3T3 cell adhesion number and strength were increased in both the Ca and Mg groups compared to the DW group. Fluorescent microscopic observation indicated that, in all groups, Sa3 had identical expression levels of integrin β4 and development of actin filaments, whereas NIH3T3 cells in the Ca and Mg groups displayed much stronger punctate cytoplasmic signals for vinculin and more bundle-shaped actin filaments than cells in the DW group. As a result, it was indicated that the hydrothermal treatment of titanium with Ca or Mg solution improved the integration of soft tissue cells with the substrata, which may facilitate the development of a soft tissue barrier around the implant.

Authors: CHOIE YOUNGJU , KOHNEN WINFRIED 
Published: March 2012

AbstractLet f be a non-zero cusp form with real Fourier coefficients a(n) (n ≥ 1) of positive real weight k and a unitary multiplier system v on a subgroup Γ ⊂ SL2(ℝ) that is finitely generated and of Fuchsian type of the first kind. Then, it is known that the sequence (a(n))(n ≥ 1) has infinitely many sign changes. In this short note, we generalise the above result to the case of entire modular integrals of non-positive integral weight k on the group Γ0*(N) (N ∈ ℕ) generated by the Hecke congruence subgroup Γ0(N) and the Fricke involution $W_N:= \big(\scriptsize\begin{array}{c@{}c} 0 & -{1/\sqrt N} \\[3pt] \sqrt N & 0\\ \end{array}\big)$ provided that the associated period functions are polynomials.
ON THE DISTRIBUTION OF -FREE NUMBERS AND NON-VANISHING FOURIER COEFFICIENTS OF CUSP FORMS
Authors: MATOMÄKI KAISA 
Published: March 2012

AbstractWe study properties of -free numbers, that is numbers that are not divisible by any member of a set . First we formulate the most-used procedure for finding them (in a given set of integers) as easy-to-apply propositions. Then we use the propositions to consider Diophantine properties of -free numbers and their distribution on almost all short intervals. Results on -free numbers have implications to non-vanishing Fourier coefficients of cusp forms, so this work also gives information about them.

Published: March 2012

AbstractLetd> 0 be a squarefree integer and denote byh=h(−d) the class number of the imaginary quadratic field$\mathbb{Q}(\sqrt{-d})$. It is well known (see e.g. [25]) that for a given positive integerNthere are only finitely many squarefreed's for whichh(−d) =N. In [45], Saradha and Srinivasan and in [28] Le and Zhu considered the equation in the title and solved it completely under the assumptionh(−d) = 1 apart from the cased≡ 7 (mod 8) in which caseywas supposed to be odd. We investigate the title equation in unknown integers (x,y,l,n) withx≥ 1,y≥ 1,n≥ 3,l≥ 0 and gcd(x,y) = 1. The purpose of this paper is to extend the above result of Saradha and Srinivasan to the caseh(−d) ∈ {2, 3}.
Tremella diploschistina (Tremellales, Basidiomycota, Fungi), a new lichenicolous species growing on Diploschistes
Authors: MILLANES A. M. , WESTBERG M. , WEDIN M. , DIEDERICH P. 
Published: March 2012

AbstractSeveral specimens of a lichen-inhabiting Tremella, inducing the formation of pale yellow, dark brown or black galls on species of Diploschistes, have been collected in three localities in Sweden and in one locality in the USA. Morphological and molecular studies confirm that this material represents a single species, which differs from other described Tremella species in the combination of gall morphology, basidium morphology, basidium and basidiospore sizes, presence of thick-walled hyphidia, and a different host-selection. We consequently describe this fungus as Tremella diploschistina sp. nov., on the basis of morphology and phylogenetic analyses of ITS and nLSU sequences. The phylogenetic analyses reveal that the fungus clearly belongs in Tremella, although the relationships with other species in the genus remain unclear.

AbstractThe foliicolous lichenized fungus Calopadia erythrocephala Farkas, Elix & Flakus, is described as new to science from the Atlantic submontane rainforests in Brazil. The species is very similar to C. puiggarii, but is distinguished by the presence of a red pigment in the campylidia, the darker apothecial discs and larger conidia. Fusarubin, the red pigment produced by the new species, is reported for the first time from foliicolous lichens. A world-wide key to foliicolous species of Calopadia with single, muriform ascospores is presented.

The Auto Parts-Automotive Chain in Mexico and China: Co-operation Potential?
Authors: Peters Enrique Dussel 
Published: March 2012

AbstractMexico's economic relationship with China has intensified substantially in the last decade. Based on an increasing literature on the overall and aggregate relationship, this analysis proposes a detailed examination of the auto parts-automobile chain, which is of utmost importance for both countries and will be significant for understanding the future trade relationship between them. In order to understand the industrial organization of Mexico and China, the article first gives an overview of the international trade and industrial organization patterns. After establishing the characteristics of Mexico's and China's legal framework, production, employment and trade, the analysis concludes with a group of proposals to improve binational co-operation. Both countries – China interested in increasing its export platform based on Chinese parts brands and Mexico supplying parts and components and providing decades of experiences in international networks – can benefit from these suggestions and overcome current tensions.
Online Chinese Perceptions of Latin America: How They Differ from the Official View
Authors: Shen Simon 
Published: March 2012

AbstractUsing online Chinese communities as primary sources, this article studies public perceptions in China of Latin America in terms of how the region is seen as part of the Third World while also offering China a convenient backyard by which to access the First World United States. Codified online public opinion on four different Latin American topics is then analysed and compared with official opinion: how “Latin Americanization” becomes China's nightmare, how the Latin Americans should learn from the “China model,” how the Latin Americans were being discriminated in the H1N1 epidemic, and how the “Latin American card” to balance the United States is emphasized. The conclusion suggests that only when the stereotypes discussed in this article are dismissed will the true value of Latin America gradually obtain any standing in the eyes of ordinary Chinese and will the Latin American mission of the Chinese government be fully understood by its subjects.
The Intellectuals of Italian Catholic Action and the Sacralisation of Politics in 1930s Europe
Authors: DAGNINO JORGE 
Published: March 2012

AbstractThere has been a growing revival of interest in the subject of political religion in recent years. However, despite this tendency, the perspective of contemporary Italian Catholics on the subject has hardly been touched upon, except by Emilio Gentile and Renato Moro. This article addresses this gap, analysing the response to the phenomenon of political religions during the 1930s by the two intellectual branches of Italian Catholic Action, namely, the FUCI and the Movimento laureati. Indeed, it was during the 1930s that these intellectuals became most aware of the novelty and danger posed by the emergence of the political religions. The article follows the analyses provided by the FUCI and the Movimento laureati on Bolshevism, National Socialism and Italian Fascism. During the 1930s new concepts such as ‘political religions’, ‘religion of the blood’, ‘totalitarian religion’ and ‘new idols’, all expressed the effort of these Catholic intellectuals to come to terms with the new reality of the sacralisation of politics being carried out by the totalitarian experiments.
Heroism, Raison d'état, and National Communism: Red Nationalism in the Cinema of People's Poland
Authors: KUNICKI MIKOŁAJ 
Published: March 2012

AbstractUsing archival sources, film reviews, interviews, secondary sources and movies, this article examines a Polish nationalist-communist school of directors who supported the Communist Party regime in constructing a new ethos, which consisted of ethnocentric nationalism and authoritarian nation state ideology. It demonstrates how the party state tried to legitimise itself by endorsing popular culture, specifically mainstream cinema. It also argues that National Communism inevitably led to the nationalist-authoritarian fusion, which set up the conditions for a pluralist and polyphonic realm, outside, but also within the ruling camp.
Civic pride and redevelopment in the post-war British city
Authors: SHAPELY PETER 
Published: March 2012

ABSTRACT:This article is concerned with civic pride in post-war urban Britain. While many of the development projects during 1945–79 proved to be design failures, suggesting the demise of civic pride, the ambitions of local authorities, planners and developers have largely been ignored or dismissed. Nevertheless, the development plans which emerged during this period reveal a desire to rebuild new, modern and vibrant cities. Moreover, the planning and financing of these new projects highlights the structure of local governance in post-war Britain, with a shift towards new partnerships consisting of the council, the technocrat and the developer. As such, civic pride continued to be evident in the post-war period, both as an aspiration for urban development and as a symbolic form of power.
Cities in late medieval Europe: the promise and the curse of modernity
Authors: BOONE MARC 
Published: March 2012

ABSTRACT:This article examines how modern historiography has developed quite differentiated views on the way medieval cities have given expression to renewal and to creativity. ‘National’ traditions have played a highly influential role in modifying the general views articulated in the major syntheses produced by scholars such as Max Weber and Henri Pirenne at the beginning of the twentieth century. An almost jubilant way of looking at the city as the hotbed of modernity gave room, in the decades after the Great War, to pessimism and a negative view on urbanity, before a more nuanced and positive view has been re-established after World War II and in the course of recent paradigmatic changes.
