Antecedents and consequences of online brand and anti-brand community participation

This study aims to propose and empirically test an integrated model of antecedents and consequences of online brand and anti-brand community participation. A common conceptual framework of online brand and anti-brand community participation is proposed. Multiple identifications (i.e., moral identification, brand identification and brand disidentification), brand emotion and motives are proposed as the antecedents of community participation. Community citizenship behavior is used to measure the consequences of community participation. A total of 260 responses from online brand communities and 200 responses from online anti-brand communities were collected via online survey. The sample was recruited by posting the research links across 409 online brand communities and 690 online anti-brand communities of 142 global brands. This was based on a consolidated list of top 100 global brands from BusinessWeek's 100 Best Global Brands and Millward Brown's BrandZ Top 100 Most Valuable Global Brands. The result models of online brand and online anti-brand community participation from structural equation modelling analysis indicate the asymmetric impacts of antecedents on motives and community citizenship behavior. Academically, the findings have extended the theory of social identity, emotion, organizational citizenship behavior, together with the newly developed motives of online community participation to explain the results and the differences between these two models from a multiple stakeholders' perspective. The results of the qualitative and quantitative research have revealed the existence of multiple stakeholders such as brand supporters, brand opponents, activists, and peer groups existing in the communities. Further research is suggested to seek to understand their behavior, dynamics and interaction among each other in a qualitative and longitudinal manner. Recommendations of online community setup, design and activities are proposed in this study to trigger different stakeholders’ participation in the online brand and anti-brand communities for motivating their voluntary community citizenship behavior to the sustainability of the communities. Proactive measures in online anti-brand community are proposed to deal with users’ dissatisfactions and identify product and service improvement to fulfil unmet needs.

Modeling of a sensor used for RFA based dental implant stability measurement

The objective of the present study is to model a sensor used for determination of dental implant stability using resonance frequency analysis. The aim of modelling is to identify the parameters that affect its response so that the model could be used to suggest better design of the sensor. The sensor system consists of a piezo element attached to a metallic strip with some adhesive. The response of the sensor is highly dependent on the shape and size of the piezo element as well as on the shape and size of the metallic strip attached to it. Three different shapes of the metallic strip, namely circular type, cross type and L type, are glued onto a thin radial piezo element. To validate the model, experimental studies have been done using all three different designs of the sensor. The average responses of the sensors obtained experimentally, the simulated responses obtained using the model and the corresponding error curves have been compared and certain parameters have been identified which affect the sensor performance.
Anatomic variations found on dissection of depressor septi nasi muscles in cadavers.

OBJECTIVES To define variations of the depressor septi muscle in Iranians; to provide guidance for modification of this muscle during rhinoplasty in patients with an active muscle and short upper lip; and to correlate our findings with our clinical experience to develop the applied algorithms. METHODS This study was conducted by dissecting 82 depressor septi nasi muscles in 41 Iranian cadavers. Origin and insertion points of each muscle were studied. RESULTS Three variations were found in muscle insertion points: periosteal, orbicularis oris, and floating. Forty-four percent of the muscles were inserted into the periosteum of the maxilla (n = 36); 39% of muscles were inserted into the orbicularis oris muscle (n = 32); and 17% were diminutive or floating (n = 14). Periosteal insertion was thicker and stronger than the other variations. In all cadavers, the origin of the muscle was medial crus of alar cartilage and caudal of the nasal septum. CONCLUSIONS This cadaveric dissection showed that the percentage of depressor septi muscle insertions is not similar to that found in other surveys. In this study, periosteal insertion of the depressor septi muscle was the most common variation.
Structured State Feedback Controllers and Optimal Submanifold Stabilization

We study optimal stabilization of submanifolds. We show that the adjoint equation of the Hamiltonian formalism associated with such optimal control problems has structured solutions. As a consequence, optimal controls for submanifold stabilization are necessarily structured state feedbacks. In particular, we show that optimal controllers depend linearly on a function mapping to the normal spaces of the submanifold. We connect our findings to the classical linear quadratic regulator via classes of Riccati differential equations and algebraic Riccati equations. We illustrate our findings on the synchronization problem, on the broadcasting problem, and on the pattern generator problem.
Gastroduodenal stenting with Niti‐S stent: Long‐term benefits and additional stent intervention

Self‐expandable metallic stents have mainly been used for the palliation of malignant gastric outlet obstruction (GOO). However, their use in long‐term survivors and the feasibility, safety and benefit of additional intervention for stent dysfunction remain controversial. The present study examined the long‐term benefits of endoscopic gastroduodenal stenting.
Towards Anticipating IS Consequences: An Anatomy of Sociotechnical Interaction Networks (STINs)

In this paper we examine questions of how the unintended impacts of information and communications technology can be examined in order to anticipate and safeguard against negative consequences. Using the domain of the eGovernment impacts on marginalized members of the community, we examine the theoretical basis of the sociotechnical interaction network (STIN) approach and its applicability to identifying and ameliorating negative impacts of ICT-based systems. We illustrate the STIN modelling approach with reference to a case study of an integrated eGovernment system and based on our evaluation of the approach, make recommendations regarding future developments with respect to the STIN framework.
A Forgotten Method to Induce Experimental Chronic Renal Failure in the Rat by Ligation of the Renal Parenchyma

Background: Animal models of chronic renal failure have been widely used in the experimental nephrology laboratories. The most common technique used is the 5/6 reduction of renal mass, either by surgical resection or by infarction. Methods: In the present work, we describe a forgotten technique based in the ligation of the renal parenchyma in both renal poles. This technique combines the advantages of the resection model, like the reproducibility and homogeneity, with the ones of the infarction technique, like the absence of bleeding. Results: 8 weeks after the procedure, animals showed a decrease in creatinine clearance together with an increase in plasma creatinine. Furthermore, glomeruli of animals with 5/6 nephrectomy showed a marked hypertrophy, with a glomerular volume significantly higher than control animals. Serum levels of parathyroid hormone were also increased, consistent with the development of secondary hyperparathyroidism. Conclusions: We conclude that the present technique is a valid and improved tool for the study of chronic renal failure.
Transfer and Replication of Organizational Capabilities: Japanese Transplant Organizations in the United States

Organizational theory has long held that it is difficult to transfer organizations from one environment to another and that organizations that are transferred will take on characteristics of the new environment. We argue that organizations have the capabilities and the resources to transfer and to some degree replicate key capabilities in a new environment, and further to alter those environments in light of their functional requirements. We explore the question of organizational transfer and replication through the lens of a specific class of transplant organizations—Japanese automotive assembly plants and their suppliers in the United States. We believe that these transplant organizations provide an ideal case to explore such questions because they represent organizations which are being transferred from a supportive to a foreign environment. We find that these Japanese automotive transplants have effectively transferred and to some degree replicated key organizational forms and capabilities at both the intraand inter-organizational levels.
Inferring Shared Interests from Social Networks

Many online community platforms such as LibraryThing, last.fm, flickr, and CiteULike store data about users, friend relationships between users, and for each user a list of items he interacted with. Depending on the usage scenario, items may be books, songs, pictures, or scientific publications, respectively. In social network analysis it is widely assumed that people tend to gather in groups of shared interests, where such interests drive friendships and vice versa. The same assumption is made in citation networks. Citation networks are directed and acyclic, where social networks are symmetric and have small diameter.
A Thin-Film , Large-Area Image Compression System for Sensing and Detection

Compressive information acquisition is a natural approach for low-power hardware front ends, since most natural signals are sparse in some basis. Key design questions include the impact of hardware impairments (e.g., nonlinearities) and constraints (e.g., spatially localized computations) on the fidelity of information acquisition. Our goal in this paper is to obtain specific insights into such issues through modeling of a Large Area Electronics (LAE)-based image acquisition system. We show that compressive information acquisition is robust to stochastic nonlinearities, and that appropriately designed spatially localized computations are effective, by evaluating the performance of reconstruction and classification based on the information acquired.
Reliability of the Fugl-Meyer assessment for testing motor performance in patients following stroke.

BACKGROUND AND PURPOSE The purpose of this study was to establish the interrater reliability of assessments made with the Fugl-Meyer evaluation of physical performance in a rehabilitation setting. SUBJECTS Twelve patients (7 male, 5 female), aged 49 to 86 years (mean = 66), who had sustained a cerebrovascular accident participated in the study. All patients were admitted consecutively to a rehabilitation center and were between 6 days and 6 months poststroke. METHODS Three physical therapists, each with more than 10 years of experience, assessed the patients in a randomized and balanced order using this assessment. The therapists standardized the assessment approach prior to the study but did not discuss the procedure once the study began. RESULTS The overall reliability was high (overall intraclass correlation coefficient = .96), and the intraclass correlation coefficients for the subsections of the assessment varied from . 61 for pain to . 97 for the upper extremity. CONCLUSION AND DISCUSSION The relative merits of using the Fugl-Meyer assessment as a research tool versus a clinical assessment for stroke are discussed.
Isolation of the outer membranes from Treponema pallidum and Treponema vincentii

The outer membranes from Treponema pallidum subsp. pallidum and Treponema vincentii were isolated by a novel method. Purified outer membranes from T. pallidum and T. vincentii following sucrose gradient centrifugation banded at 7 and 31% (wt/wt) sucrose, respectively. Freeze fracture electron microscopy of purified membrane vesicles from T. pallidum and T. vincentii revealed an extremely low density of protein particles; the particle density of T. pallidum was approximately six times less than that of T. vincentii. The great majority of T. vincentii lipopolysaccharide was found in the outer membrane preparation. The T. vincentii outer membrane also contained proteins of 55 and 65 kDa. 125I-penicillin V labeling demonstrated that t. pallidum penicillin-binding proteins were found exclusively with the protoplasmic cylinders and were not detectable with purified outer membrane material, indicating the absence of inner membrane contamination. Isolated T. pallidum outer membrane was devoid of the 19-kDa 4D protein and the normally abundant 47-kDa lipoprotein known to be associated with the cytoplasmic membrane; only trace amounts of the periplasmic endoflagella were detected. Proteins associated with the T. pallidum outer membrane were identified by one- and two-dimensional electrophoretic analysis using gold staining and immunoblotting. Small amounts of strongly antigenic 17- and 45-kDa proteins were detected and shown to correspond to previously identified lipoproteins which are found principally with the cytoplasmic membrane. Less antigenic proteins of 65, 31 (acidic pI), 31 (basic pI), and 28 kDa were identified. Compared with whole-organism preparations, the 65- and the more basic 31-kDa proteins were found to be highly enriched in the outer membrane preparation, indicating that they may represent the T. pallidum rare outer membrane proteins. Reconstitution of solubilized T. pallidum outer membrane into lipid bilayer membranes revealed porin activity with two estimated channel diameters of 0.35 and 0.68 nm based on the measured single-channel conductances in 1 M KCl of 0.40 and 0.76 nS, respectively.
Evaluating design approaches for smart building systems

As we are moving towards to the Internet of Things (IoT) era, Wireless Sensor Networks (WSN) in smart buildings delineate the heart of such systems¿ architecture. WSN systems are mature enough to support the IoT vision and different architectural designs and communication protocols are developed to realize this vision. In this paper, two different WSN architectural approaches for smart building systems are presented. In the first one, IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) deployment is used, which is designed specifically for constrained embedded devices. In the second one, the system is developed without the usage of IP. To evaluate these two approaches we implemented a scenario of a smart building environment on top of them. We analyze and compare them, both from theoretical and practical point of view. Finally, as a proof of concept we evaluated them experimentaly in our testbed and we reported our conclusions.
Nutrient conditions in the subpolar North Atlantic during the last glacial period reconstructed from foraminifera‐bound nitrogen isotopes

[1] Surface nitrate concentration is a potentially useful diagnostic in reconstructing the past circulation of high-latitude North Atlantic waters. Moreover, nutrient consumption in the North Atlantic surface impacts the atmospheric concentration of carbon dioxide. To reconstruct nutrient conditions in the subpolar North Atlantic region during the last ice age, a record of foraminifera-bound δ15N was measured in Neogloboquadrina pachyderma (sin.) from core V28-73 south of Iceland (57.2°N, 20.9°W). Foraminifera-bound δ15N is up to 2‰ lower during the last ice age than during the Holocene, suggesting as much as ~25% less complete nitrate consumption during the former. This is consistent with stronger light limitation associated with a deeper summer surface mixed layer, perhaps related to the formation of Glacial North Atlantic Intermediate Water previously suggested to have occurred near the core site. However, three single-point maxima in δ15N in the glacial section and the sharp deglacial δ15N rise coincide with Heinrich event layers. This suggests that increased water column stratification during Heinrich events, presumably due to surface freshening, reduced the nutrient supply from below and led to nearly complete nitrate consumption in the summertime mixed layer. The Heinrich layers in V28-73 are not accompanied by δ18O minima in either N. pachyderma (sin.) or Globigerinoides bulloides, which we tentatively attribute to extreme mixed-layer shoaling. The reconstructed subpolar North Atlantic upper water column changes—both glacial/interglacial and millennial—are inverse to those inferred for the Antarctic.
The role of ATP‐sensitive potassium channels in cellular function and protection in the cardiovascular system

ATP‐sensitive potassium channels (KATP) are widely distributed and present in a number of tissues including muscle, pancreatic beta cells and the brain. Their activity is regulated by adenine nucleotides, characteristically being activated by falling ATP and rising ADP levels. Thus, they link cellular metabolism with membrane excitability. Recent studies using genetically modified mice and genomic studies in patients have implicated KATP channels in a number of physiological and pathological processes. In this review, we focus on their role in cellular function and protection particularly in the cardiovascular system.
3D Face Recognition by Deforming the Normal Face

3D face recognition is complicated by the presence of expression variation. In this paper, we present an automatic 3D face recognition method which can differentiate the expression deformations from the interpersonal differences and recognize faces with expressions being removed. The deformations caused by expression and interpersonal difference are firstly learnt from training set, respectively. Then the deformations are linearly combined to synthesize new face with certain expression. When a target face comes in, the synthesized face is used to match it by adjusting the coefficients in the linear combination. After the matching process, coefficients corresponding to the interpersonal differences are chosen as features for recognition. We perform experiments on the FRGC v2.0 database and good performance is obtained.
Study on streaming electrification properties of palm fatty acid ester (PFAE) oil due to aging

Palm fatty acid ester (PFAE) is mono ester oil which has better cooling property than mineral oil and other poly esters. Recently, natural ester has been tested on extra high voltage large power transformer. Large power transformers have a risk of streaming electrification. Many studies have been conducted to investigate streaming electrification properties of mineral oil immersed transformers and their countermeasures. However, streaming electrification properties of natural esters are rarely studied. Therefore, this paper presents a study on streaming electrification properties of PFAE due to aging. PFAE and mixed oils were prepared under several conditions. Aging test was conducted by heating the oil samples at 100 °C for 360, 720, 1080 and 1440 hours. The results show that heating causes various trends of volume resistivity and positive increases in electrostatic charging tendency (ECT) with respect to aging time. At initial state, ion dissociation on additive compound decreases volume resistivity and increases ECT. However, during the heating, the dissociation is not accelerated. Additive compound is dissociated into radicals to mitigate oxidation. In the mixture of 20% mineral oil and 80% PFAE, higher changes in volume resistivity and ECT indicate that degradation is more likely to occur in mineral oil part. In addition, air circumstance has effects on volume resistivity and ECT.
Should a platelet limit of 600 × 109/l be used as a diagnostic criterion in essential thrombocythaemia? An analysis of the natural course including early stages

In order to evaluate the natural history of essential thrombocythaemia (ET), clinical data and prognostic factors of 143 patients with ET were retrospectively analysed (mean observation time 6.1 ± 4.6 years). In 42 patients the early phase of the disease with initial platelet counts between 250 and 600 × 109/l was assessed. In most early cases, ET was suggested by clinical symptoms (79%) and increased megakaryopoiesis (95%) with abnormal megakaryocytes in bone marrow histology (n = 34) and cytology (n = 5). Other myeloproliferative disorders and reactive thrombocytosis were excluded according to the diagnostic criteria of the Polycythemia Vera Study Group. During follow‐up of the 38 early cases not treated cytoreductively at diagnosis, the platelet counts increased to >600 × 109/l in 28 patients (74%) and remained between 450 and 600 × 109/l in 10 patients (26%). In primarily asymptomatic patients (n = 46) with initial platelet counts above (n = 37) and below 600 × 109/l (n = 9) the rates of increase of symptomatic patients were similar at about 7% per year. No influence of the initial platelet count on survival was seen in multivariate analysis of prognostic factors which included all 143 cases. Survival was mainly influenced by the rate of ET‐related complications during follow‐up (P = 0.002). Analysing the influence of cytoreductive therapy on symptom‐free survival, platelet reduction benefited patients under 60 years (19 cytoreductively treated v 65 untreated patients, P = 0.075). The results demonstrate the possible clinical relevance of the early stages of ET and suggest that the features of pathologic megakaryopoiesis in the bone marrow are a more reliable diagnostic criterion than a definite platelet limit. Therefore, further therapeutic studies should include all stages of the disease and all age groups.
Characterization of 12 polymorphic microsatellite loci for the whitespotted bamboo shark (Chiloscyllium plagiosum Bennett)

Twelve polymorphic microsatellite loci without linkage disequilibrium were isolated and characterized from a microsatellite DNA‐enriched DNA library for the whitespotted bamboo shark (Chiloscyllium plagiosum Bennett, 1830). These loci show polymorphism information content ranging from 0.384 to 0.885, allele number ranging from 4 to 12, effective allele number ranging from 1.686 to 9.438, and observed and expected heterozygosities from 0.229 to 1.000 and from 0.407 to 0.894 respectively. Four loci show strong Hardy–Weinberg deviations. We expect that these markers would be useful for population genetic and breeding studies of the whitespotted bamboo shark.
