Reexamining supply chain integration and the supplier's performance relationships under uncertainty
Authors: Huang Ming-Chang , Yen Ghi-Feng , Liu Tzu-Chuan 
Published: January 2014

Purpose– Effective and efficient supply chain coordination requires the integration of all product flow processes. However, inconsistent empirical results have been obtained with respect to the relationships between supply chain integration (SCI) and performance. Drawing on efficiency-flexibility arguments, this paper seeks to develop a SCI model that includes buyer-supplier-supplier relationships, and proposes a contingency framework for reexamining the SCI-supplier performance relationship under demand and technological uncertainties.Design/methodology/approach– A two-stage data collection process was conducted, and a total of 878 suppliers that listed in the Taiwanese “Center-Satellite Production System” with supply contract were contacted for this study. Finally 164 suppliers were gathered and screened as valid responses. Hierarchical regression analysis was used to test the hypotheses in this study.Findings– Evidence indicates that SCI has a significant positive effect on the suppliers' performance. The positive SCI-performance relationship can be moderately weakened by demand uncertainty; however, this positive SCI-performance relationship will be strengthened by technological uncertainty.Originality/value– While supply chain management is needed to manage the vertical and horizontal relationships simultaneously, this study offers a framework to solve efficiency-flexibility dilemma arguments when dealing with “exploitation” and “exploration” alternatives to help to reexamine the inconsistent SCI-performance relationship. Furthermore, based on transaction cost theory, this paper takes the nature of uncertainty into account for improving the theoretical background of the SCI-performance relationship arguments. Empirical results indicate the existence of an ambidextrous supply chain integration strategy which justifies the choice of which one is preferable in efficiency-flexibility dilemma arguments.
Supply chain as an autopoietic learning system
Authors: Breite Rainer , U. Koskinen Kaj 
Published: January 2014

Purpose– This paper seeks to present a comprehensive overview of the supply chain as an autopoietic system. The new autopoietic approach suggests a transition from traditional cognitivist epistemology to the theory of learning as a creational matter, and this type of thinking can potentially shed light on the role of knowledge creation as a part of supply chain management.Design/methodology/approach– The paper is structured as follows: the first section describes the theoretical background of the concept of knowledge management in the supply chain. After that, the paper examines the general systems theory and the role of an autopoietic system within it. Then the paper addresses autopoietic epistemology. In particular, the notions of knowledge, learning, and knowledge flows are described so that the focus is on the context of the supply chain and supply chain management at operational level.Findings– The supplier's, customer's, and firm's own organization and parts of the organization have autonomy system memories, which ultimately formulate how the intended development ideas are in fact realized and how they are adopted by the organization. Supply chain managers should take into account the fact that the routines and norms of the node are part of the system that are not controlled from outside. Instead, the system can modify its objectives internally as part of its autonomous operation, which should be taken into consideration in the knowledge sharing process.Originality/value– The description of a supply chain as an autopoietic knowledge system is a new way to examine knowledge sharing in a supply chain.

Authors: Lv Na , Zhong Jiyong , Wang Jifeng , Chen Shanben 
Published: January 2014

Purpose
– Surface forming control of welding bead is the fundamental study in automated welding. Considering that the vision sensing system cannot extract the height information of weld pool in pulsed GTAW process, so this paper designed a set of automatic measurement and control technology to achieve real-time arc height control via audio sensing system. The paper aims to discuss these issues.

Design/methodology/approach
– The experiment system is based on GTAW welding with acoustic sensor and signal conditioner. A combination denoising method was used to reduce the environmental noise and pulse interference noise. After extracting features of acoustic signal, the relationship between arc height and arc sound pressure was established by linear fitting. Then in order to improve the prediction accuracy of that model, the piecewise linear fitting method was proposed. Finally, arc height linear model of arc sound signal and arc height is divided into two parts and built in two different arc height conditions, which are arc height 3-4 and 4-5-6 mm.

Findings
– The combination denoising method was proved to have great effect on reducing the environmental noise and pulse interference noise. The experimental results showed that the prediction accuracy of linear model was not stable in different arc height changing state, like 3-4 and 4-5-6 mm. The maximum error was 0.635588 mm. And the average error of linear model was about 0.580487 mm, and the arc sound signal was accurately enough to meet the requirement for real-time control of arc height in pulse GTAW.

Originality/value
– This paper tries to make a foundation work to achieve controlling of depth of welding pool through arc sound signal, then the welding quality control. So a new idea of arc height control based on automatic measuring and processing system through arc sound signal was proposed. A new way to remove environmental noise and pulse interference noise was proposed. The results of this thesis had proved that arc sound signal was an effective features and precisely enough for online arc height monitoring during pulsed GTAW.

Infrared receptors of pyrophilous jewel beetles as model for new infrared sensors
Authors: Kahl Thilo , Bousack Herbert , S. Schneider Erik , Schmitz Helmut 
Published: January 2014

Purpose
– Early detection of forest fires offers the chance to put the fire out before it gets out of control. The purpose of this paper is to look into nature and to learn how certain insects detect remote forest fires. A small group of highly specialized insects that have been called pyrophilous is attracted by forest fires and approaches fires sometimes from distances of many kilometers. As a unique feature some of these insects are equipped with infrared (IR) receptors, which in case of two species of jewel beetles (family Buprestidae) are used for fire detection.

Design/methodology/approach
– The paper has investigated the IR receptors of the pyrophilous beetles with various morphological techniques including scanning electron microscopy, transmission electron microscopy, neuroanatomy and the paper also investigated the thermo-/mechanical properties of the IR receptors by nanoindentation. Data were used for subsequent modeling of a biomimetic technical sensor. Finally, a macroscopic prototype was built and tested.

Findings
– This biological principle was transferred into a new kind of uncooled technical IR receptor. A simple model for this biological IR sensor is a modified Golay sensor in which the gas has been replaced by a liquid. Here, the absorbed IR radiation results in a pressure increase of the liquid and the deflection of a thin membrane. For the evaluation of this model, analytical formulas are presented, which permits the calculation of the pressure increase in the cavity, the deformation of the membrane and the time constant of an artificial leak to compensate ambient temperature changes. Some organic liquids with high thermal expansion coefficients may improve the deflection of the membrane compared to water.

Originality/value
– Results so far obtained suggest that it seems promising to take the photomechanic IR receptors of pyrophilous jewel beetles as models for the building of new uncooled IR sensors. The beetle receptors have been shaped by evolution since thousands of years and, therefore, can be considered as highly optimized sources of inspiration for new technical sensors suitable for remote fire detection.

ABSTRACTDevelopment of complementary and/or alternative drugs for treatment of hepatitis C virus (HCV) infection is still much needed from clinical and economic points of view. Antiviral substances obtained from medicinal plants are potentially good targets to study. Glycyrrhiza uralensis and G. glabra have been commonly used in both traditional and modern medicine. In this study, extracts of G. uralensis roots and their components were examined for anti‐HCV activity using an HCV cell culture system. It was found that a methanol extract of G. uralensis roots and its chloroform fraction possess anti‐HCV activity with 50%‐inhibitory concentrations (IC50) of 20.0 and 8.0 μg/mL, respectively. Through bioactivity‐guided purification and structural analysis, glycycoumarin, glycyrin, glycyrol and liquiritigenin were isolated and identified as anti‐HCV compounds, their IC50 being 8.8, 7.2, 4.6 and 16.4 μg/mL, respectively. However, glycyrrhizin, the major constituent of G. uralensis, and its monoammonium salt, showed only marginal anti‐HCV activity. It was also found that licochalcone A and glabridin, known to be exclusive constituents of G. inflata and G. glabra, respectively, did have anti‐HCV activity, their IC50 being 2.5 and 6.2 μg/mL, respectively. Another chalcone, isoliquiritigenin, also showed anti‐HCV activity, with an IC50 of 3.7 μg/mL. Time‐of‐addition analysis revealed that all Glycyrrhiza‐derived anti‐HCV compounds tested in this study act at the post‐entry step. In conclusion, the present results suggest that glycycoumarin, glycyrin, glycyrol and liquiritigenin isolated from G. uralensis, as well as isoliquiritigenin, licochalcone A and glabridin, would be good candidates for seed compounds to develop antivirals against HCV.
Prevalence of musculoskeletal complaints and juvenile idiopathic arthritis in children from a developing country: a school‐based study
Authors: Abujam Bonnie , Mishra Rishabh , Aggarwal Amita 
Published: January 2014

AbstractIntroductionMusculoskeletal complaints are common in children. Studies from developed countries have found most to be non‐inflammatory and juvenile idiopathic arthritis (JIA) to be less than 0.1%. However, there is limited data from developing countries such as India.MethodsThis cross‐sectional study was conducted from March 2010 to April 2011 among school children aged 6–17 years in northern India. Prevalence of musculoskeletal complaints and JIA were determined using a questionnaire on musculoskeletal complaints. This was filled either by parents (always in children < 14 years) or children themselves. Subsequently, all children were individually met and responses verified. An abbreviated musculoskeletal examination (GALS) was performed on every child. In cases of suspected inflammatory arthritis, further investigations were performed.ResultsOf the 2059 children (851 girls, 1208 boys) who were included in this study, mean (± SD) age was 11.5 ± 2.9 years. Joint pain (more than 1 week) was present in 158 (7.6%), back pain in 63 (3.1%) and heel pain in 62 (3%) of them. Limb pains, suggestive of ‘growing pains’, were present in 45 (2.1%) children. There were six suspected cases of inflammatory musculoskeletal pain; however, only one child was confirmed as having JIA (enthesitis‐related arthritis). The estimated prevalence of JIA was 48/100 000 in Indian children.ConclusionMusculoskeletal complaints were not uncommon in children from a developing country like India. Estimated prevalence of JIA was 48/100 000 (95%CI 10–280).

Published: January 2014

BackgroundReported incidence and survival from in‐hospital and out‐of‐hospital cardiac arrest show great variability, making it difficult to compare the groups. In order to eliminate effects of time and culture, we investigated out‐of‐hospital cardiac arrest compared with in‐hospital cardiac arrest in our community over a 1‐year period.MethodsWe conducted a cohort study including patients with in‐hospital and out‐of‐hospital cardiac arrest. Multiple data sources were screened in order to identify all cardiac arrest patients. Utstein style data were collected prospectively from 1 December 2008 to 30 November 2009 with subsequent analysis.ResultsA total of 380 resuscitations because of cardiac arrest were included, 154 (40.6%) in‐hospital and 226 (59.4%) out‐of‐hospital. The in‐hospital cardiac arrest group was older, had higher proportions of witnessed cardiac arrest, bystander cardiopulmonary resuscitation, bystander direct current (DC) shock and professional first rescuer. Survival to hospital discharge was 16.2% for in‐hospital cardiac arrest vs. 16.8% for out‐of‐hospital cardiac arrest.ConclusionSurvival from in‐hospital and out‐of‐hospital cardiac arrest in this cohort is similar.

Abstract

The present study was conducted using mark–released populations of male Agriotes obscurus (AO) and Agriotes lineatus (AL) adults to simulate the spatial and temporal capture rates of wild beetle populations in dense arrays of pheromone traps in a confined, nonfarmed habitat.
Two parallel rows of traps, spaced 3 m apart along corridors of grassy dyke, recaptured 85.6% of AO and 77.8% of AL with arrays of their respective pheromone traps, mostly within the first week of release. In arrays of mixed AO and AL traps, recapture rates were 77.8% and 83.3%, respectively.
In arrays with only AO traps, 31.2% of AL males released within the arrays mistakenly entered the AO traps, which declined to only 2.2% when released in arrays with both AO and AL traps. In arrays with only AL traps, only 0.7% of released AO were mistakenly taken in the AL traps, and only 0.3% mistakenly entered AL traps in mixed AO and AL trap arrays.
Between 34.4–38.9% of AO and 21.1–25.6% of AL released in areas immediately adjacent to the trapping arrays were caught, mostly in the outermost traps.
The implications of these results for determining the efficacy of mass trapping as a click beetle management approach are discussed.
Bach and His
Authors: Beasley Wyn 
Published: January 2014

AbstractThis paper examines the career of Johann Sebastian Bach (1685–1750) and the role played by Wilhelm His I (who was, with Albert von Haller, a noted pioneer of physiology) in the exhumation of Bach's remains in 1894. His's examination of these remains allowed the sculptor Carl Seffner to produce the celebrated statue of Bach which stands outside the church of St Thomas in Leipzig, where the composer was employed from 1723 until his death. Modern forensic techniques have recently enabled Bach's image to be reconstructed in even more spectacular detail.

Published: January 2014

AbstractRecent advances in medical and device therapies in heart failure have improved the survival of patients with heart failure. However, due to the limited availability of suitable heart donors, left ventricular assist devices (LVADs) have become an important tool as a bridge‐to‐heart transplantation for patients with refractory heart failure in Singapore. We report our experience with the HeartMate II (HMII) LVAD (Thoratec Corporation, Pleasanton, CA, USA) as a bridge‐to‐heart transplant in our center from 2009 to 2012. This was a retrospective review of 23 consecutive patients who underwent HMII LVAD implantation in our center between May 2009 and December 2012. All patients were classified as Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) levels 1 to 3 and underwent LVAD implantation as a bridge‐to‐heart transplant. There were 17 male and 6 female patients. The mean age was 43.6 years old (range 14 to 64). The etiologies of heart failure included ischemic heart disease [8], idiopathic dilated cardiomyopathy [11], viral myocarditis [2], and chemotherapy‐induced cardiomyopathy [2]. Nine patients were INTERMACS level 1, 12 patients level 2, and two patients level 3. All patients successfully underwent HMII LVAD implantation. There was no mortality within the first 30 postoperative days. Postoperative complications included stroke with full neurological recovery (21.7%), mediastinal infection (21.7%), cardiac tamponade or mediastinal collection requiring reopening of the chest (39.1%), cardiac arrhythmia (13.0%), and pump thrombosis with pump replacement (4.3%). All patients were discharged from hospital after LVAD implantation. Three patients experienced driveline infections during outpatient follow‐up. There were 19 readmissions due to the following conditions: sub‐therapeutic anticoagulation (13.0%), gastrointestinal bleeding (13.0%), suspected pump thrombosis (13.0%), transient ischemic attack (8.7%), arrhythmia (8.7%), congestive cardiac failure due to severe aortic regurgitation (8.7%), right ventricular failure (4.3%), rhabdomyolysis (4.3%), and hematuria (4.3%). Post‐LVAD implantation, 20 patients were functionally New York Heart Association (NYHA) class I, while 3 reported NYHA III symptoms. Three patients were successfully bridged to heart transplantation. One patient was successfully explanted 11 months after LVAD implantation. There were two mortalities during the follow‐up period. The average duration of LVAD support was 522 days (range 47 to 1316 days). The HeartMate II LVAD has proven to be effective in our Asian population. Driveline infection rate remains low even in the tropical hot, humid climate in Singapore. With more patients ending up on extended periods of LVAD support, increased emphasis in the detection and management of long‐term complications of ventricular assist devices will be needed.
The role of ice dynamics in shaping vegetation in flowing waters
Authors: Lind Lovisa , Nilsson Christer , Polvi Lina E. , Weber Christine 
Published: January 2014

ABSTRACTIce dynamics is an important factor affecting vegetation in high‐altitude and high‐latitude streams and rivers. During the last few decades, knowledge about ice in streams and rivers has increased significantly and a respectable body of literature is now available. Here we review the literature on how ice dynamics influence riparian and aquatic vegetation. Traditionally, plant ecologists have focused their studies on the summer period, largely ignoring the fact that processes during winter also impact vegetation dynamics. For example, the freeze‐up period in early winter may result in extensive formation of underwater ice that can restructure the channel, obstruct flow, and cause flooding and thus formation of more ice. In midwinter, slow‐flowing reaches develop a surface‐ice cover that accumulates snow, protecting habitats under the ice from formation of underwater ice but also reducing underwater light, thus suppressing photosynthesis. Towards the end of winter, ice breaks up and moves downstream. During this transport, ice floes can jam up and cause floods and major erosion. The magnitudes of the floods and their erosive power mainly depend on the size of the watercourse, also resulting in different degrees of disturbance to the vegetation. Vegetation responds both physically and physiologically to ice dynamics. Physical action involves the erosive force of moving ice and damage caused by ground frost, whereas physiological effects – mostly cell damage – happen as a result of plants freezing into the ice. On a community level, large magnitudes of ice dynamics seem to favour species richness, but can be detrimental for individual plants. Human impacts, such as flow regulation, channelisation, agriculturalisation and water pollution have modified ice dynamics; further changes are expected as a result of current and predicted future climate change. Human impacts and climate change can both favour and disfavour riverine vegetation dynamics. Restoration of streams and rivers may mitigate some effects of anticipated climate change on ice and vegetation dynamics by, for example, slowing down flows and increasing water depth, thus reducing the potential for massive formation of underwater ice.
Transactional Links Between Teacher–Child Relationship Quality and Perceived Versus Sociometric Popularity: A Three‐Wave Longitudinal Study
Authors: De Laet Steven , Doumen Sarah , Vervoort Eleonora , Colpin Hilde , Van Leeuwen Karla , Goossens Luc , Verschueren Karine 
Published: January 2014

This study examined how peer relationships (i.e., sociometric and perceived popularity) and teacher–child relationships (i.e., support and conflict) impact one another throughout late childhood. The sample included 586 children (46% boys), followed annually from Grades 4 to 6 (Mage.wave1 = 9.26 years). Autoregressive cross‐lagged modeling was applied. Results stress the importance of peer relationships in shaping teacher–child relationships and vice versa. Higher sociometric popularity predicted more teacher–child support, which in turn predicted higher sociometric popularity, beyond changes in children's prosocial behavior. Higher perceived popularity predicted more teacher–child conflict (driven by children's aggressive behavior), which, in turn and in itself, predicted higher perceived popularity. The influence of the “invisible hand” of both teachers and peers in classrooms has been made visible.
