Published: May 2017

Abstract
Die Globalisierung hat in den letzten Jahrzehnten zu einer Dezentralisierung der Produktion sowie der Entstehung global verteilter Produktionsnetzwerke geführt. Produktionsnetzwerke ermöglichen es Unternehmen, neue Absatzmärkte zu erschließen und lokale Produktionsvorteile zu nutzen. Gleichzeitig stellen die Vielzahl Beteiligter sowie Zielkonflikte und Intransparenzen sowohl Planer als auch Entscheider vor Herausforderungen. Der vorliegende Beitrag erläutert Herausforderungen im Management globaler Produktionsnetzwerke auf strategischer, gestalterischer und operativer Planungsebene. Er zeigt Ansätze auf, die je Planungsebene einen bestmöglichen Umgang mit den Hürden ermöglichen. Der Beitrag beschreibt zudem, wie durch eine ganzheitliche und Ebenen übergreifende Betrachtung Verbesserungen im Management von Produktionsnetzwerken erzielt werden können.*)

Published: June 2017

BACKGROUND: Lower back pain has a lifetime prevalence of 80% for people in a modern society, and in recent years, spinal stabilization movement has been highlighted as a method to treat lower back pain and an unbalanced position. OBJECTIVE: The objectives of this study were to assess the trunk muscle activities in accordance with the tilt angles (10[Formula: see text], 20[Formula: see text], 30[Formula: see text], 40[Formula: see text]) during trunk tilt exercises with a 3D dynamic exercise device. METHODS: Active tilt mode (a self-generated active movement in the angle and direction steered by the user) was used in this study. The rotation capability enabled the investigation of the anterior (A), anterior right (AR), right (R), posterior right (PR), posterior (P), posterior left (PL), left (L), and anterior left (AL) tilt directions. EMG signals of the trunk (3 global muscles: rectus abdominis, RA, external obliques, EO, latissimus dorsi, LD, and 1 local muscle: multifidus, MF) muscles were obtained. RESULTS: The MF muscle activity was higher while the anterior tilt was maintained, and the abdominal muscle activity was higher while the posterior tilt was maintained. Also, as the tilt angle increased, the activity of the muscles opposite the tilt direction increased. CONCLUSIONS: The results indicate that to maintain equilibrium through posture stabilization during whole body tilting, the human body maintains a proper interaction among the body segments as well as between the body and the execution environment. Moreover, stability is maintained through the co-contraction of antagonistic and agonistic muscles. In future studies, it will be important to conduct research on improving imbalance in the trunk muscles.

Published: June 2017

BACKGROUND: Stroke is a frequently-occurring disease and is a severe threat to human health. OBJECTIVE: We aimed to explore the associations between stroke risk factors. METHODS: Subjects who were aged 40 or above were requested to do surveys with a unified questionnaire as well as laboratory examinations. The Apriori algorithm was applied to find out the meaningful association rules. Selected association rules were divided into 8 groups by the number of former items. The rules with higher confidence degree in every group were viewed as the meaningful rules. RESULTS: The training set used in association analysis consists of a total of 985,325 samples, with 15,835 stroke patients (1.65%) and 941,490 without stroke (98.35%). Based on the threshold we set for the Apriori algorithm, eight meaningful association rules were obtained between stroke and its high risk factors. While between high risk factors, there are 25 meaningful association rules. CONCLUSIONS: Based on the Apriori algorithm, meaningful association rules between the high risk factors of stroke were found, proving a feasible way to reduce the risk of stroke with early intervention.
Potential for false positive results from multi-voxel pattern analysis on functional imaging data
Authors: Zhang Zuo , Jiang Youhao , Sun Yaoru , Zhang Hong 
Published: June 2017

BACKGROUND: Multi-voxel pattern analysis (MVPA) provides a powerful tool to investigate neural mechanisms for various cognitive processes under functional brain imaging. However, the high sensitivity of the MVPA method could bring about false positive results, which has been overlooked by previous research. OBJECTIVE: We investigated the potential for obtaining false positives from the MVPA method. METHODS: We conducted MVPA on a public functional MRI dataset on the neural encoding of various object categories. Different scenarios for pattern classification were involved by varying the number of voxels for each region of interest (ROI) and the number of object categories. RESULTS: The classification accuracy became higher with more voxels involved, and false positive results emerged for the primary auditory cortex and even a white matter ROI, where object-related neural processing was not supposed to occur. CONCLUSIONS: Our results imply that the classification accuracy obtained from MVPA may be inflated due to the high sensitivity of the method. Therefore, we suggest involving control ROIs in future MVPA studies and comparing the classification accuracy for a target ROI with that for a control ROI, instead of comparing the obtained accuracy with the chance-level accuracy.
Design of an ultrasonic physiotherapy system with pulse wave feedback control
Authors: Peng Ran , Luo Yang , Li Zhangyong , Wang Wei , Pang Yu 
Published: June 2017

BACKGROUND: Due to different physical and biological mechanisms behind ultrasound hyperthermia and phonophoresis, the requirement for ultrasound power, frequency and control modes varies. OBJECTIVE: This paper introduces an adaptive ultrasonic physiotherapy system based on real-time surveillance over physiological characteristics of the patients, which in turn assists the individual treatment and dose limitation in auxiliary rehabilitation. METHODS: The method essentially takes advantage of distinctive characteristics of two different phases (systole and diastole) of the human cardiac cycle as a medium for modulation. The abundance of blood flow during systole enables energy exchange for hyperthermia while blood flow insufficiency caused by diastole assists in drug penetration. Said method could improve the adjuvant therapy as it provides partial drug penetration and therapeutic dosage control. RESULTS: By adjusting time window and intensity of multi-frequency ultrasound, it is possible to reduce the irradiation dosage to around 22% of that during continuous irradiation at 1 MHz. The method shows high potential in clinical practice. CONCLUSION: Frequency-tuning ultrasound therapy would be more efficient regarding drug penetration and improve the therapeutic efficacy of hyperthermia.

Published: June 2017

BACKGROUND: The ischemia penumbra area is not easy to be detected accurately using noninvasive imaging methods. OBJECTIVE: We aim to assess the diagnostic value of susceptibility-weighted imaging (SWI) for ischemic penumbra in patients with acute ischemic stroke. METHODS: A retrospective analysis was carried out in 47 patients with ischemic stroke involving the middle cerebral artery. Mean transit time (MTT), time to peak, relative cerebral blood flow, and relative cerebral blood volume maps were created after image processing. RESULTS: No significant difference was found in the mismatch between the SWI and diffusion-weighted imaging (SWI-DWI) or in the MTT-DWI mismatch scores ([Formula: see text] 0.056, Kappa [Formula: see text] 0.864). CONCLUSIONS: SWI provides information comparable to PWI and, thus, could serve as a reliable magnetic resonance technique for assessing ischemic penumbrae.

Published: May 2017

Introduction: In recent years, some studies have shown an increase in cardiovascular risk due to the use of calcium supplements in excess of the recommended doses. One hypothesis is that some calcium supplements lead to a more pronounced elevation of serum calcium concentrations.
Objectives: The aim of this study was to evaluate the serum calcium responses after ingestion of calcium carbonate, with and without the prior use of omeprazole, and after ingestion of soluble fiber enriched milk (SFM).
Method: Five postmenopausal women were evaluated in three phases. For each phase, the serum calcium responses were determined at 0h (baseline), 1h, 2h, 3h and 4h. After ingestion of 1200mg of calcium, both for the patients who received the calcium carbonate and for those who received SFM. The rise in serum calcium observed after ingestion of calcium carbonate with a calcium peak of 0.56 mg/dl (p=0.032), and it was higher when compared to SFM 0.26 mg/dl (p=0.284). There was no significant elevation of serum calcium after ingestion of SFM.
Results: The calcium responses were negative after the administration of omeprazole in comparison with the use of calcium carbonate and SFM, reaching 7.06mg/dl vs 9.04mg/dl vs 9.12mg/dl at 0h, 5.30mg/dl vs 9. 32mg/dl vs 9.00mg/dl at 1hr, 5.52mg/dl vs 9.48mg/dl vs 9.32mg/dl at 2hr, 5.18mg/dl vs 9.48mg/dl vs 9.34mg/dl at, respectively. In conclusion, our data show that the same amount of SFM induced a lower serum calcium response when compared to calcium carbonate.
Conclusion: The use of omeprazole significantly reduced the intestinal absorption of calcium carbonate.
An Investigation of Blazars without Redshifts: Not a Missing Population at High Redshift
Authors: Mao Peiyuan , Urry C. Megan 
Published: May 2017

Abstract
We investigate a sample of 622 blazars with measured fluxes at 12 wavebands across the radio-to-gamma-ray spectrum but without spectroscopic or photometric redshifts. This sample includes hundreds of sources with newly analyzed X-ray spectra reported here. From the synchrotron peak frequencies, estimated by fitting the broadband spectral energy distributions (SEDs), we find that the fraction of high-synchrotron-peaked blazars in these 622 sources is roughly the same as in larger samples of blazars that do have redshifts. We characterize the no-redshift blazars using their infrared colors, which lie in the distinct locus called the WISE blazar strip, then estimate their redshifts using a KNN regression based on the redshifts of the closest blazars in the WISE color–color plot. Finally, using randomly drawn values from plausible redshift distributions, we simulate the SEDs of these blazars and compare them to known blazar SEDs. Based on all these considerations, we conclude that blazars without redshift estimates are unlikely to be high-luminosity, high-synchrotron-peaked objects, which had been suggested in order to explain the “blazar sequence”—an observed trend of SED shape with luminosity—as a selection effect. Instead, the observed properties of no-redshift blazars are compatible with a causal connection between jet power and electron cooling, i.e., a true blazar sequence.
Toward a Greater Understanding of the Reduction of Drift Coefficients in the Presence of Turbulence
Authors: Engelbrecht N. E. , Strauss R. D. , Roux J. A. le , Burger R. A. 
Published: May 2017

Abstract
Drift effects play a significant role in the transport of charged particles in the heliosphere. A turbulent magnetic field is also known to reduce the effects of particle drifts. The exact nature of this reduction, however, is not clear. This study aims to provide some insight into this reduction and proposes a relatively simple, tractable means of modeling it that provides results in reasonable agreement with numerical simulations of the drift coefficient in a turbulent magnetic field.
X-Ray Intraday Variability of Five TeV Blazars with NuSTAR
Authors: Pandey Ashwani , Gupta Alok C. , Wiita Paul J. 
Published: June 2017

Abstract
We have examined 40 Nuclear Spectroscopic Telescope Array (NuSTAR) light curves (LCs) of five TeV emitting high synchrotron peaked blazars: 1ES 0229+200, Mrk 421, Mrk 501, 1ES 1959+650, and PKS 2155−304. Four of the blazars showed intraday variability in the NuSTAR energy range of 3–79 keV. Using an autocorrelation function analysis we searched for intraday variability timescales in these LCs and found indications of several between 2.5 and 32.8 ks in eight LCs of Mrk 421, a timescale around 8.0 ks for one LC of Mrk 501, and timescales of 29.6 and 57.4 ks in two LCs of PKS 2155-304. The other two blazars’ LCs do not show any evidence for intraday variability timescales shorter than the lengths of those observations; however, the data were both sparser and noisier for them. We found positive correlations with zero lag between soft (3–10 keV) and hard (10–79 keV) bands for most of the LCs, indicating that their emissions originate from the same electron population. We examined spectral variability using a hardness ratio analysis and noticed a general “harder-when-brighter” behavior. The 22 LCs of Mrk 421 observed between 2012 July and 2013 April show that this source was in a quiescent state for an extended period of time and then underwent an unprecedented double-peaked outburst while monitored on a daily basis during 2013 April 10–16. We briefly discuss models capable of explaining these blazar emissions.

Abstract
We investigate the star formation properties of a large sample of ∼2300 X-ray-selected Type 2 Active Galactic Nuclei (AGNs) host galaxies out to

in the Chandra COSMOS Legacy Survey in order to understand the connection between the star formation and nuclear activity. Making use of the existing multi-wavelength photometric data available in the COSMOS field, we perform a multi-component modeling from far-infrared to near-ultraviolet using a nuclear dust torus model, a stellar population model and a starburst model of the spectral energy distributions (SEDs). Through detailed analyses of SEDs, we derive the stellar masses and the star formation rates (SFRs) of Type 2 AGN host galaxies. The stellar mass of our sample is in the range of

with uncertainties of ∼0.19 dex. We find that Type 2 AGN host galaxies have, on average, similar SFRs compared to the normal star-forming galaxies with similar M
stellar and redshift ranges, suggesting no significant evidence for enhancement or quenching of star formation. This could be interpreted in a scenario, where the relative massive galaxies have already experienced substantial growth at higher redshift (

), and grow slowly through secular fueling processes hosting moderate-luminosity AGNs.

Abstract
We present the results of very long baseline interferometry (VLBI) observations of gamma-ray bright blazar S5 0716+714 using the Korean VLBI Network (KVN) at the 22, 43, 86, and 129 GHz bands, as part of the Interferometric Monitoring of Gamma-ray Bright active galactic nuclei (iMOGABA) KVN key science program. Observations were conducted in 29 sessions from 2013 January 16 to 2016 March 1, with the source being detected and imaged at all available frequencies. In all epochs, the source was compact on the milliarcsecond scale, yielding a compact VLBI core dominating the synchrotron emission on these scales. Based on the multiwavelength data between 15 GHz (Owens Valley Radio Observatory) and 230 GHz (Submillimeter Array), we found that the source shows multiple prominent enhancements of the flux density at the centimeter (cm) and millimeter (mm) wavelengths, with mm enhancements leading cm enhancements by −16 ± 8 days. The turnover frequency was found to vary between 21 and 69 GHz during our observations. By assuming a synchrotron self-absorption model for the relativistic jet emission in S5 0716+714, we found the magnetic field strength in the mas emission region to be ≤5 mG during the observing period, yielding a weighted mean of 1.0 ± 0.6 mG for higher turnover frequencies (e.g., >45 GHz).

Objective.To assess the longterm frequency of thrombotic recurrences, obstetrical complications, organ damage, severe comorbidities, and evolution toward connective tissue disease (CTD) in primary antiphospholipid syndrome (PAPS).Methods.Medical records of patients with PAPS followed in 6 centers for ≥ 15 years were retrospectively reviewed.Results.One hundred fifteen patients were studied: 88% women, followed between 1983 and 2014 with a mean (± SD) age at diagnosis of 33 (± 10) years. During a median followup of 18 years (range 15–30), 50 patients (44%) had at least a thrombotic event for a total of 75 events and an annual incidence of 3.5%. Thromboses were more frequent in patients with previous thrombotic history (p = 0.002). A catastrophic antiphospholipid syndrome occurred in 6 patients (5%). The use of oral anticoagulants in patients with thrombotic onset did not appear to be protective against recurrences (p = 0.26). Fifty-two women had 87 pregnancies, successful in 78%. Twenty-nine percent of patients accrued functional damage. Damage was significantly associated with a thrombotic history (p = 0.004) and with arterial events (p < 0.001), especially stroke, but not with demographics, serology, or treatment. Twenty-four major bleeding episodes were recorded in 18 patients, all receiving anticoagulants. Severe infections affected 6 patients (5%), with 1 fatality. A solid cancer was diagnosed in 8 patients (7%). Altogether, 16 patients (14%) developed an autoimmune disease and 13 (11%) a full-blown picture of CTD.Conclusion.Despite therapy, a high proportion of patients experienced new thrombotic events and organ damage, while evolution toward CTD was infrequent.
Rendre la mondialisation viable : les leçons de l'Europe
Authors: Cœuré Benoît 
Published: May 2017

La mondialisation suscite aujourd'hui de graves inquiétudes alors que des signes de démondialisation apparaissent. Or nombre des critiques reposent sur des idées reçues. Pour rendre la mondialisation viable - plus efficace, plus durable et plus équitable -, il importe que les États soient forts et œuvrent dans le cas d'une gouvernance solide. Sur le plan économique, un libre-échange bénéfique suppose que les gouvernements en gèrent correctement les conséquences sociales, environnementales et celles qui touchent à la répartition des revenus. Dans l'ensemble, l'intégration européenne, tentative la plus élaborée mise en œuvre pour gérer les arbitrages politiques d'un environnement mondialisé, est une réussite et peut donc servir d'exemple. Toutefois, pour qu'elle soit elle-même viable, plusieurs actions doivent être menées : la rendre plus durable en améliorant la qualité des flux financiers et également la rendre plus équitable. Enfin il est nécessaire que l'Europe prouve pleinement sa capacité à se faire entendre dans les institutions internationales. Classification JEL : F02, F55, F60, F65, F68.
La « révolution des transports » à Rio de Janeiro au service de la valorisation urbaine et de la politique d’expropriations : le projet du BRT Transoeste
Authors: Mendes Alexandre , Legroux Jean 
Published: May 2017

Le BRT ( Bus Rapid Transit ) Transoeste , qui relie la zone de Barra da Tijuca à la zone ouest de la ville de Rio de Janeiro, a été présenté, lors de son inauguration, comme l’un des principaux « héritages olympiques » et comme une « révolution des transports » pour la population carioca –, résultant de l’action conjointe des différents niveaux de gouvernement brésiliens. Cet article cherche à problématiser le projet sur la base des contradictions observées à partir du fonctionnement du système de transport – sa saturation et sa surcharge, la mauvaise qualité des travaux, les accidents – et des effets socio-spatiaux induits par son implantation, conduisant à l’expropriation forcée de centaines d’habitants de favelas.
Athletic Trainers' Perceptions of and Barriers to Patient Care Documentation: A Report From the Athletic Training Practice-Based Research Network
Authors: Bacon Cailee E. Welch , Eppelheimer Bradly L. , Kasamatsu Tricia M. , Lam Kenneth C. , Nottingham Sara L. 
Published: June 2017

Context:
For the practice characteristics of the services athletic trainers (ATs) provide to be identified, all ATs must complete high-quality patient care documentation. However, little is known about ATs' perceptions of patient care documentation or the potential barriers they may encounter while trying to ensure high-quality documentation.

Objective:
To explore ATs' perceptions of and barriers to patient care documentation via the Clinical Outcomes Research Education for Athletic Trainers (CORE-AT) electronic medical record system in the secondary school setting.

Design:
Qualitative study.

Setting:
Individual telephone interviews.

Patients or Other Participants:
We interviewed 10 ATs (4 men, 6 women; age = 32.6 ± 11.4 years, athletic training experience = 7.1 ± 7.8 years) who were members of the Athletic Training Practice-Based Research Network (AT-PBRN) and employed in the secondary school setting.

Data Collection and Analysis:
We conducted an individual interview with each participant. After transcription of the interviews, the data were analyzed into common themes and categories following the consensual qualitative research tradition. Data triangulation occurred through member checking and multiple researchers to ensure accuracy during data analysis.

Results:
Participants revealed several perceptions of patient care documentation, consisting of quality, expectations and accountability, priority, incentive, and culture of the secondary school setting. In addition, we identified barriers to quality patient care documentation: lack of time, lack of accountability for documenting patient care, inadequate facility resources, and lack of personnel. Participants discussed the volume of patients as a unique challenge in the secondary school setting.

Conclusions:
Whereas ATs perceived patient care documentation as important, several practical barriers may inhibit their ability to complete high-quality documentation of the services they provide. Effective strategies to improve the quality of patient care documentation among ATs are needed to ensure that their value, particularly in the secondary school setting, is accurately characterized.
