Delegation ärztlicher Leistungen an nichtärztliche Fachkräfte: Der Versorgungsansatz agneszwei in Brandenburg – eine qualitative Akzeptanzanalyse
Authors: Schmiedhofer M. , Brandner S. , Kuhlmey A. 
Published: November 2015

Zusammenfassung
Hintergrund: Als Antwort auf den zunehmenden Mangel hausärztlicher Versorgung in ländlichen Regionen wurden Projekte durchgeführt, bei denen ärztliche Tätigkeiten an qualifizierte Medizinische Fachangestellte oder Krankenpfleger/innen delegiert werden. Evaluationen zeigen hohe Zufriedenheitswerte bei allen beteiligten Akteur/inn/en. Dieser Beitrag untersucht die Kooperationsbeziehung der Gesundheitsberufe in einer um Fallmanagement erweiterten Versorgungsstruktur mit der Delegation ärztlicher Aufgaben agneszwei in Brandenburg qualitativ.
Methode: 10 leitfadengestützte qualitative Experteninterviews wurden mit 6 Ärzt/inn/en und 4 Krankenpflegerinnen/Medizinischen Fachangestellten geführt.
Ergebnisse: Die Zusammenarbeit wird von beiden Berufsgruppen als gut beschrieben und in der Versorgungsstruktur ein Vorteil für die Patientinnen und Patienten gesehen. Die strikte Anerkennung des ärztlichen Tätigkeitsvorbehaltes wird dabei als Voraussetzung erfolgreicher Zusammenarbeit benannt. Die ärztlichen Expert/inn/en werden in ihrem Alltag entlastet. Die Fachkräfte ziehen aus einer erfolgreich aufgebauten Vertrauensbeziehung zu den Patient/inn/en berufliche Zufriedenheit. Eine Implementierung von Delegationstätigkeiten in die Regelversorgung wird von allen Fachkräften uneingeschränkt befürwortet, während die Mehrheit der Ärzt/inn/en trotz guter Bewertung des eigenen Projektes skeptisch bis ablehnend ist.
Schlußfolgerung: Trotz der hohen Akzeptanz der teilweisen Übernahme medizinischer Aufgaben steht der standespolitische Aushandlungsprozeß neuer kooperativer Arbeitsformen in der ambulanten Versorgung erst am Anfang.

Published: November 2015

ZusammenfassungEine Gewichtszunahme in der Schwangerschaft oberhalb der IOM-Empfehlungen erhöht das Risiko für Schwangerschaftskomplikationen und für späteres Übergewicht bei Mutter und Kind. Deshalb sollten Schwangere hinsichtlich ihrer Zunahme entsprechend beraten werden. Welche Bedürfnisse haben Frauen bezüglich der Beratung? Hierzu wurden 34 Schwangere in offenen Interviews befragt, welche mit der Frequenzanalyse nach Mayring ausgewertet wurden. Es wurde erkannt, dass die gesundheitlichen Auswirkungen einer zu starken Gewichtszunahme von den Frauen unzureichend wahrgenommen werden. Weiterhin konnten 4 verschiedene Verhaltensweisen bezüglich der Ernährung abgeleitet werden: (i) Schwangere, die zwar gut informiert sind, dies jedoch nicht umsetzen; (ii) Schwangere, die Informationen und Wissen konsequent umsetzen, (iii) Schwangere, die sich vom Körpergefühl leiten lassen; und (iv) vorwiegend indifferente Schwangere. Frauen, die schon vor der Schwangerschaft inaktiv waren, ließen sich auch in der Schwangerschaft nicht zu Sport motivieren. Für die Planung zukünftiger Interventionen sollte berücksichtigt werden, dass Informationsbedarf hinsichtlich der Gewichtszunahme und gesunder Ernährung in der Schwangerschaft besteht. Abhängig vom Verhaltensmuster der Frau wird eine Ernährungsintervention nicht immer den gewünschten Erfolg erzielen. Weiterhin ist die Motivation und Aufklärung zu geeigneten Sportarten eine besondere Herausforderung.
Why should ethics approval be required prior to publication of health promotion research?
Authors: Newson Ainsley J. , Lipworth Wendy 
Published: November 2015

Issue addressedMost academic journals that publish studies involving human participants require evidence that the research has been approved by a human research ethics committee (HREC). Yet journals continue to receive submissions from authors who have failed to obtain such approval. In this paper, we provide an ethical justification of why journals should not, in general, publish articles describing research that has no ethics approval, with particular attention to the health promotion context.MethodsUsing theoretical bioethical reasoning and drawing on a case study, we first rebut some potential criticisms of the need for research ethics approval. We then outline four positive claims to justify a presumption that research should, in most instances, be published only if it has been undertaken with HREC approval.ResultsWe present four justifications for requiring ethics approval before publication: (1) HREC approval adds legitimacy to the research; (2) the process of obtaining HREC approval can improve the quality of an intervention being investigated; (3) obtaining HREC approval can help mitigate harm; and (4) obtaining HREC approval demonstrates respect for persons.ConclusionThis paper provides a systematic and comprehensive assessment of why research ethics approval should generally be obtained before publishing in the health promotion context.
An Approximate Markov Model for the Wright-Fisher Diffusion
Authors: Ferrer-Admetlla Anna , Leuenberger Christoph , Jensen Jeffrey D. , Wegmann Daniel 
Published: November 2015

ABSTRACTThe joint and accurate inference of selection and demography from genetic data is considered a particularly challenging question in population genetics, since both process may lead to very similar patterns of genetic diversity. However, additional information for disentangling these effects may be obtained by observing changes in allele frequencies over multiple time points. Such data is common in experimental evolution studies, as well as in the comparison of ancient and contemporary samples. Leveraging this information, however, has been computationally challenging, particularly when considering multi-locus data sets. To overcome these issues, we introduce a novel, discrete approximation for diffusion processes, termedmean transition time approximation, which preserves the long-term behavior of the underlying continuous diffusion process. We then derive this approximation for the particular case of inferring selection and demography from time series data under the classic Wright-Fisher model and demonstrate that our approximation is well suited to describe allele trajectories through time, even when only a few states are used. We then develop a Bayesian inference approach to jointly infer the population size and locus-specific selection coefficients with high accuracy, and further extend this model to also infer the rates of sequencing errors and mutations. We finally apply our approach to recent experimental data on the evolution of drug resistance in Influenza virus, identifying likely targets of selection and finding evidence for much larger viral population sizes than previously reported.

The recently published method for the structure refinement from three-dimensional precession electron diffraction data using dynamical diffraction theory [Palatinuset al.(2015).Acta Cryst.A71, 235–244] has been applied to a set of experimental data sets from five different samples – Ni2Si, PrVO3, kaolinite, orthopyroxene and mayenite. The data were measured on different instruments and with variable precession angles. For each sample a reliable reference structure was available. A large series of tests revealed that the method provides structure models with an average error in atomic positions typically between 0.01 and 0.02 Å. The obtained structure models are significantly more accurate than models obtained by refinement using kinematical approximation for the calculation of model intensities. The method also allows a reliable determination of site occupancies and determination of absolute structure. Based on the extensive tests, an optimal set of the parameters for the method is proposed.
A pipeline for the rapid generation of difference maps from protein crystals
Authors: Wojdyr Marcin , Keegan Ronan , Winter Graeme , Ashton Alun , Lebedev Andrey , Krissinel Eugene 
Published: November 2015

In 2013 MX beamlines at the Diamond synchrotron deployed an automated software pipeline, called DIMPLE, for rapid processing of crystals that contain a known protein and possibly a ligand bound. DIMPLE takes the already known "apo" structure for the target protein, compares it with the electron density map from X-ray diffraction images, and visualizes areas of the electron density unaccounted for by the structure model. When processing batches of crystals, such feedback allows the user to better decide what to measure next which leads to a more efficient use of the beam time. This year we've enhanced the pipeline to cover more complex cases, including changes in the space group and some changes in conformation. With multiple molecular replacement computations run in parallel, the time from shooting to viewing the difference map is still only a few minutes. While the software is developed primarily for use at synchrotron beamlines, it is included in the CCP4 suite and can be used as well for in-house automation.
Color Symmetry of Certain Tilings with a Singular Center
Authors: Evidente Imogene , Felix Rene , Loquias Manuel Joseph 
Published: November 2015

Tilings with singular points, or tilings that are not locally finite, are classified in [1] among tilings that are not "well-behaved". In [2], colorings of tilings with a singular center were obtained from certain colorings of regular Euclidean tilings. It was observed that not all such colorings could be transformed into colorings of tilings with a singularity. Moreover, the existence of maximum color indexes was surmised. In this paper, we provide a mathematical basis for the said observations by utilizing conformal maps that distort a regular Euclidean tiling into a tiling with a singular center. That is, we determine conditions so that a coloring of a regular Euclidean tiling can be transformed into a coloring of a tiling with a singular center. In addition, we establish that a maximum number of colors exists. Finally, we give conditions so that the symmetry group of the tiling with a singular center induces a permutation of the colors.

The history of Crystallography in Argentina is very rich, probably starting with the pioneer work of Prof. Ernesto Galloni in the decade of the `40s. Thanks to Prof. Galloni, the National Committee of Crystallography was founded in 1958 and recognized by the IUCr in 1960. This committee organized several scientific meetings and was in good contact with the Ibero American Crystallography Group during about 35 years. After some crisis in the late `90s, some young crystallographers decided to reorganize the activities and form the Argentinian Association of Crystallography (AACr), which was finally founded on October 30th, 2004, on the occasion of the "National Workshop on Crystallography" held in Villa Giardino, Province of Córdoba. Therefore, in the International Year of Crystallography, the AACr is also celebrating its tenth anniversary. The regular annual events of the AACr are a scientific meeting, a school on Crystallography and a workshop. This year, they will be held in Mar del Plata (Province of Buenos Aires) in the period of October 27th-Novembre 7th. In addition, many other academic activities such workshops or postgraduate courses are being organized in the whole country. It is worth to remark the School on Fundamental Crystallography to be held in La Plata, followed by an Agilent-UNESCO-IUCr OpenLab in La Plata and Buenos Aires, in April-May. Moreover, taking into account that Crystallography is a field that needs more promotion in our country, the AACr decided to propitiate several educational and dissemination activities. They include a national crystal growing contest, promotion of Crystallography in high and primary schools through the National Fairs of Science of the Ministry of Education, dissemination talks for different audiences, exhibitions, etc. Acknowledgements: The AACr thanks all the crystallographers that are working hard in these activities: G. Echeverría, O. Piro, S. Suárez, M. Saleta, D. Tobía, R. Carbonio, G. Aurelio, J. Pedregosa, F. Doctorovich, S. Conconi, L. Baqué, F. Napolitano, S. Alconchel, C. Alvarez, A. Ares, C. Bernini, S.

Crystal structure of the human COP9 signalosome
Authors: Bunker Richard , Lingaraju Gondichatnahalli , Thomä Nicolas 
Published: November 2015

The COP9 signalosome (CSN) is a multifunctional ~350 kDa eight-protein complex with highly-specific isopeptidase activity, which regulates the vast cullin-RING family of ubiquitin ligases (CRLs). Ubiquitin ligases direct target-specific ubiquitination and are involved in a multitude of regulatory processes, ultimately linked to protein turnover by the proteosome. Humans have a repertoire of approximately 240 CRLs, more than any other ubiquitin ligase family. The entire human CSN has been structurally characterised de novo using low-resolution (4-Å) X-ray crystallography. The crystallographic analysis was complicated by rotational pseudo-symmetry and twinning, non-isomorphism as well as the absence of experimental phase information beyond ~8 Å resolution. Details of the structure determination procedures, which combined a cluster compound-based phasing strategy, analysis of seven differentially substituted selenomethionyl derivatives, multi-crystal averaging among non-isomorphous data sets with a multi-crystal co-refinement approach, will be described. Some implications of the structure and insight into the regulation of CSN will also be presented.

Authors: Gourhant Patrick , Guimaraes Beatriz , Isabet Tatiana , Klinke Sebastian , Legrand Pierre , Rinaldi Jimena , Thompson Andrew 
Published: November 2015

PROXIMA 1, a beamline for macro-molecular crystallography at the 3rd generation synchrotron source SOLEIL, is equipped with a multi-circle goniometer (alpha 50 degrees) as well as a PILATUS 6M detector. These features, along with the extended energy range of the beam line towards the low energies (down to 5.5 keV) and the possibility to adapt the source size to the sample in order to optimize signal to noise ratio, have made the beam line very attractive for S-SAD phasing with more than seven examples of successful de novo phasing achieved over the last two years. The use of low energies has also proved a significant aid in assisting with MODEL building. The technical capabilities of the beam line for low energy data collections will be presented, along with a number of examples of the successful use of low wavelengths on the beam line. The importance of combining data from multiple sample orientations in order to achieve "true multiplicity" will be highlighted, as well as the importance of combining data from multiple crystals in order to achieve high multiplicity.

Purpose– The purpose of this paper is to establish a link between marketing resources, procurement process coordination (PPC) and firm performance. To allow for greater understanding in the field of supply chain management, the present study looked into the coordination between the construction firms and their main building materials suppliers.Design/methodology/approach– This study employed the quantitative method where stratified random sampling and self-administrated questionnaires were sent to respondents in the construction industry. The research framework was tested using structural equation modelling technique.Findings– The empirical result revealed that marketing resources have positive and significant effects on PPC dimensions. It was also found that PPC (mainly joint operation planning and supplier relationship development dimensions) has significant positive relationship towards firm performance.Research limitations/implications– This study focused solely on the firms in the construction industry and data collection was on a single respondent basis.Practical implications– The findings of this study underlines some implication and suggests that construction industry players adopt and emphasise such orientations in order to enhance their performance – operational and customer performance in particular.Originality/value– This study employed a newly developed framework based on the existing theoretical arguments to empirically examine the link between marketing resources, PPC and firm performance and offers fresh insights on the effects of PPC in linking marketing resources and firm performance. Besides that, since there are very limited studies that have taken the initiative to specifically list down the activities involved in the PPC, mainly in the context of the construction industry, this study offers a significant contribution.
Risk factors affecting practitioners’ attitudes toward the implementation of an industrialized building system
Authors: Luo Li-zi , Mao Chao , Shen Li-yin , Li Zheng-dao 
Published: November 2015

Purpose– An industrialized building system (IBS) is regarded as an effective residential building system that provides several benefits, including high quality, low cost, short time, good flexibility, reduced waste, and strong environmental performance. This system is considered to be valuable in promoting sustainable practices in China, where plans for urbanization have been established. However, the adoption of IBS in China is extremely limited. Potential risks exist and affect the attitudes of practitioners toward the use of this system. The purpose of this paper is to prioritize and analyze these risks and to develop corresponding strategies for mitigating these risks in China.Design/methodology/approach– In total, 24 risks that inhibit the implementation of IBS in China are identified through literature review and examined through interviews for consistency. A questionnaire survey is conducted to quantify the significance of these risks. Cronbach’s coefficientαis employed to measure the internal consistency among the risk factors. The survey results are further analyzed using three case studies.Findings– The top five risks identified are “poor cooperation between multi-interface,” “inappropriate design codes and standards for industrialized buildings,” “lack of management practices and experiences,” “enormous difficulty in achieving return on high initial investment,” and “lack of a quality monitoring mechanism for the production process.” The findings emphasize the government’s leading role in promoting the new building system in its introduction and enforcement of adequate policies and regulations. Practitioners are also instrumental in establishing proper understanding and knowledge of IBS and its application.Originality/value– This study bridges the knowledge gaps on risk identification for implementing IBS in China. The findings provide practitioners and decision makers with valuable references for adopting adequate risk management methods and policies to promote IBS in China.
Control and synchronization of a hyperchaotic finance system via single controller scheme
Authors: He Ping , Li Yangmin 
Published: November 2015

Purpose
– The purpose of this paper is to study the control and synchronization of the hyperchaotic finance system.

Design/methodology/approach
– A single controller scheme is introduced. The Routh-Hurwitz criteria and the structure of solution of first-order linear differential equations are adopted in analysis of control and synchronization.

Findings
– Two single controllers are designed and added to the new hyperchaotic finance system. The stability of the hyperchaotic finance system at its zero equilibrium point is guaranteed by applying the appropriate single controller signal based on Routh-Hurwitz criteria. Another effective controller is also designed for the global asymptotic synchronization on the hyperchaotic finance system based on the structure of solution of first-order linear differential equations. Numerical simulations are demonstrated to verify the effectiveness of the proposed single controller scheme.

Originality/value
– The introduced approach is interesting for control and synchronization the hyperchaotic finance system.
