Fast and furious: how the open vs closed dilemma affects the technology diffusion dynamic
Authors: Parmentola Adele , Simoni Michele , Tutore Ilaria 
Published: February 2018

PurposeThe purpose of this paper is to propose a comprehensive theoretical framework to explain the different diffusion dynamics of a technology realized under an open source (OS) regime vs a technology realized under a closed-proprietary (CP) regime.Design/methodology/approachFollowing a systematic combining approach, theoretical predictions derived from literature on diffusion of innovation and on open innovation were matched with empirical observations derived from a case study of two mobile operation systems, which were released under different technological regimes.FindingsThis paper proposes a theoretical framework and a set of original theoretical propositions that can help to explain the differences in the diffusion dynamics of technologies that are released under different regimes (i.e. CP vs OS).Research limitations/implicationsThis paper provides managers a better understanding of the diffusion dynamics of technologies released according to an open innovation strategy. In addition, the empirical case study improves the understanding of an important industry (the MOS industry) that has not been fully investigated from the innovation diffusion perspective. Nevertheless, the efficacy and generalizability of the theoretical framework proposed in this paper require future empirical tests.Originality/valueThis paper makes an original contribution to the open innovation and innovation diffusion literature by linking, in a conceptual model, three antecedents of the diffusion of a new technology that previous literature has considered only separately: the regime under which the technology is released (OS vs CP), the contingencies related to the characteristics of the technology and to the network of its adopters, and the resulting barriers to adoption.

PurposeImplementing and maintaining Electronic Theses and Dissertations (ETDs) program at a national level encounters numerous difficulties in particular from technical, legal, business, and financial perspective. Business model (BM) is a tool to help to address business-driven challenges, such as business feasibility and viability, as one of the important aspects. The purpose of this paper is to analyze the BM practiced by different national Electronic Theses and Dissertations (NETDs) cases.Design/methodology/approachBM of seven NETDs programs have been studied through an online questionnaire; besides, programs’ websites were observed and related documents were examined. Business model canvas (BMC) was used to describe the business rationale behind the selected cases.FindingsMost of the NETDs programs lack a documented BM. The main value of these programs is sharing ETDs which is offered to academics through online channels; skillful staff and proper hardware/software are their main resources to do so. Furthermore, their key activities are developing hardware/software and negotiating with ETDs owners as their key partners. All these activities required huge cost which is generally covered by public funding.Originality/valueThis study pioneers in applying BM concept into field of NETDs. Therefore, the major contribution of this study is to provide an analysis of NETDs programs’ BM through BMC. Furthermore, the paper provides recommendations on how ETDs could be implemented in a cost effective, sustainable, and viable way.

Authors: Herrando Carolina , Jimenez-Martinez Julio , Martin De Hoyos M. Jose 
Published: February 2018

Purpose
Social commerce websites entail a completely new scenario for sharing experiences and opinions due to its richness in terms of social interactions. Nowadays, users can interact with the company and with other users; hence, it seems important to study how social stimuli affect users. Drawing on the stimulus-organism-response framework and flow theory, the purpose of this paper is to propose that the social stimulus (named social passion (sPassion)) has a positive effect on the organism (state of flow), which leads to a users’ positive response (via social word of mouth (sWOM)).

Design/methodology/approach
The data were collected through an online survey in 2015. The sample consists of 771 users of social commerce websites, of which 51 percent are male and 49 percent female, aged between 16 and 80 years old. Structural equation modeling was used to analyze the data with the statistical software SPSS version 22 and EQS 6.

Findings
The empirical results confirm that passionate users are prone to experience a state of flow and, as a consequence, share positive sWOM.

Originality/value
This study contributes to the literature on customers’ online participation, and the findings are hoped to help companies in developing social commerce websites that boost users’ exchange of information.

Published: February 2018

Purpose
This paper aims to provide a review of different types of non-wearable human identification sensors which can be applied for smart home environment.

Design/methodology/approach
The authors performed a systematic review to assess and compare different types of non-wearable and non-intrusive human identification sensors used in smart home environment. The literature research adds up to 5,567 records from 2000 to 2016, out of which 40 articles were screened and selected for this review.

Findings

Assessing these four group of identification technologies showed that the maturity of non-wearable identification is not high and most of these technologies are verified in a lab environment. Additionally, footstep-based identification is the most popular identification approach listed in the literature.

Originality/value
This study contributes to the literature on human identification technologies in several ways. This paper identifies the state-of-the-art regarding non-wearable technologies which can be used in smart home environment. Moreover, the results of this paper can provide a better understanding of advantages and disadvantages of the non-wearable identification technologies.
Overhead ground wire detection by fusion global and local features and supervised learning method for a cable inspection robot
Authors: Ye Xuhui , Wu Gongping , Fan Fei , Peng XiangYang , Wang Ke 
Published: February 2018

Purpose
An accurate detection of overhead ground wire under open surroundings with varying illumination is the premise of reliable line grasping with the off-line arm when the inspection robot cross obstacle automatically. This paper aims to propose an improved approach which is called adaptive homomorphic filter and supervised learning (AHSL) for overhead ground wire detection.

Design/methodology/approach
First, to decrease the influence of the varying illumination caused by the open work environment of the inspection robot, the adaptive homomorphic filter is introduced to compensation the changing illumination. Second, to represent ground wire more effectively and to extract more powerful and discriminative information for building a binary classifier, the global and local features fusion method followed by supervised learning method support vector machine is proposed.

Findings
Experiment results on two self-built testing data sets A and B which contain relative older ground wires and relative newer ground wire and on the field ground wires show that the use of the adaptive homomorphic filter and global and local feature fusion method can improve the detection accuracy of the ground wire effectively. The result of the proposed method lays a solid foundation for inspection robot grasping the ground wire by visual servo.

Originality/value
This method AHSL has achieved 80.8 per cent detection accuracy on data set A which contains relative older ground wires and 85.3 per cent detection accuracy on data set B which contains relative newer ground wires, and the field experiment shows that the robot can detect the ground wire accurately. The performance achieved by proposed method is the state of the art under open environment with varying illumination.

AbstractAtopic dermatitis is a chronic inflammatory skin disease. The objective of this study was to characterize the burden of atopic dermatitis in Japanese adult patients relative to the general population. Japanese adults (≥18 years) with a self‐reported diagnosis of atopic dermatitis and adult controls without atopic dermatitis/eczema/dermatitis were identified from the 2013 Japan National Health and Wellness Survey. Atopic dermatitis patients were propensity‐score matched with non‐atopic dermatitis controls (1:2 ratio) on demographic variables. Patient‐reported outcome data on comorbidities, mood and sleep disorders, health‐related quality of life, work productivity and activity impairment, and health‐care resource utilization were analyzed in atopic dermatitis patients and matched controls. A total of 638 Japanese adult patients with atopic dermatitis were identified, of whom 290 (45.5%) rated their disease as “moderate/severe” and 348 (54.5%) as “mild”. The analysis cohort comprised 634 atopic dermatitis patients and 1268 matched controls. Atopic dermatitis patients reported a significantly higher prevalence of arthritis, asthma, nasal allergies/hay fever, anxiety, depression and sleep disorders compared with controls (all P < 0.001). Atopic dermatitis patients also reported a significantly poorer health‐related quality of life, higher overall work and activity impairment, and higher health‐care resource utilization (all P < 0.001). Self‐rated disease severity was not associated with disease burden, except for a significantly higher overall work and activity impairment. In conclusion, Japanese adult patients with atopic dermatitis reported a substantial disease burden relative to adults without atopic dermatitis, suggesting an unmet need for effective strategies targeting disease management.
Special AT‐rich sequence binding protein 1 is required for maintenance of T cell receptor responsiveness and development of experimental autoimmune encephalomyelitis

Published: February 2018

ABSTRACTThe genome organizer special AT‐rich sequence binding protein 1 (SATB1) regulates specific functions through chromatin remodeling in T helper cells. It was recently reported by our team that T cells from SATB1 conditional knockout (SATB1cKO) mice, in which the Satb1 gene is deleted from hematopoietic cells, impair phosphorylation of signaling molecules in response to T cell receptor (TCR) crosslinking. However, in vivo T cell responses upon antigen presentation in the absence of SATB1 remain unclear. In the current study, it was shown that SATB1 modulates T cell antigen responses during the induction and effector phases. Expression of SATB1 was upregulated in response to TCR stimulation, suggesting that SATB1 is important for this antigen response. The role of SATB1 in TCR responses and induced experimental autoimmune encephalomyelitis (EAE) was therefore examined using the myelin oligodendrocyte glycoprotein peptide 35‐55 (MOG35‐55) and pertussis toxin. SATB1cKO mice were found to be resistant to EAE and had defects in IL‐17‐ and IFN‐γ‐producing pathogenic T cells. Thus, SATB1 expression appears necessary for T cell function in the induction phase. To examine SATB1 function during the effector phase, a tamoxifen‐inducible SATB1 deletion system, SATB1cKO‐ER‐Cre mice, was used. Encephalitogenic T cells from MOG35‐55‐immunized SATB1cKO‐ER‐Cre mice were transferred into healthy mice. Mice that received tamoxifen before the onset of paralysis were resistant to EAE. Furthermore, no disease progression occurred in recipient mice treated with tamoxifen after the onset of EAE. Thus, SATB1 is essential for maintaining TCR responsiveness during the induction and effector phases and may provide a novel therapeutic target for T cell‐mediated autoimmune diseases.
Political differentiation and the problem of dominance: Segmentation and hegemony
Authors: ERIKSEN ERIK O. 
Published: February 2018

AbstractAt first glance, one might view the political differentiation in the European Union as a reflection of the autonomy of its member states, signifying flexibility and the dispersion of democratic control. However, under conditions of complex interdependence and economic integration, political differentiation can undermine the fundamental conditions for democratic self‐rule. Political differentiation may cause dominance. It is argued in this article that we must move beyond Philip Pettit's conception of dominance as the capacity to interfere with others on an arbitrary basis, in order to properly identify the undemocratic consequences of differentiation. Political freedom is also a question of institutional provisions to co‐determine laws. From this vantage point, differentiation raises the spectre of dominance in the form of decisional exclusion and the pre‐emption of political autonomy. Drawing on a re‐conceptualisation of dominance, the effects of differentiation on the possibility of self‐rule are examined, and two systematic effects of political differentiation are identified. It is argued thatsegmentationis the systemic effect of differentiation in the vertical dimension of integration. Here, dominance occurs in the form of exclusion from decision‐making bodies and the denial of choice opportunities. In the external horizontal dimension, the systemic effect of differentiation ishegemony. Some states are vulnerable to arbitrary interference and the pre‐emption of public autonomy. The article discusses developments within the Eurozone as a case of segmentation and the statues of associated non‐members as a case of hegemony. With regard to the latter, we are faced with the phenomenon of self‐incurred dominance.

AbstractAedes (Stegomyia) aegypti, the principal global vector of dengue viruses, has differences in its susceptibility to dengue virus infection. We compared the global expression of genes in the midguts of Colombian Ae. aegypti dengue‐susceptible (Cali‐S) and dengue‐refractory (Cali‐MIB) field derived strains after ingesting either a sugarmeal, a bloodmeal, or a bloodmeal containing dengue virus serotype 2 (DENV‐2). Microarray‐based transcriptome analysis among treatments indicated a total of 4725 transcripts with differential expression between the two strains. Eleven genes were selected from different functional groups based on their significant up or down expression levels as well as reports in the literature suggesting they are associated with dengue virus elimination. We measured mRNA abundance of these 11 genes at 0, 8, 24, and 36 h postinfection using quantitative real time PCR (qPCR) to confirm the microarray results and assess any temporal patterns. Four genes were selected (Gram‐negative binding protein—GNBP [AAEL009176], Niemann Pick Type‐C2—NPC2 [AAEL015136], Keratinocyte lectin [AAEL009842], and Cathepsin‐b [AAEL007585]) for knockdown experiments using RNA interference (RNAi) methodology to determine the phenotype (DENV‐2 susceptible or refractory). Silencing GNBP, Cathepsin‐b and Keratinocyte lectin reduced the percentage of mosquitoes with disseminated virus in the Cali‐S strain to 8%, 20%, and 12% respectively compared with 96% in the controls. Silencing of NPC2 increased the percentage of mosquitos with disseminated virus infections in Cali‐MIB to 66% compared with 35% in the controls. This study provides insight into genes that may contribute to the Cali‐S susceptible and Cali‐MIB refractory phenotypes in Ae. aegypti.
Effects of Emulsifier, Overrun and Dasher Speed on Ice Cream Microstructure and Melting Properties
Authors: Warren Maya M. , Hartel Richard W. 
Published: February 2018

AbstractIce cream is a multiphase frozen food containing ice crystals, air cells, fat globules, and partially coalesced fat globule clusters dispersed in an unfrozen serum phase (sugars, proteins, and stabilizers). This microstructure is responsible for ice cream's melting characteristics. By varying both formulation (emulsifier content and overrun) and processing conditions (dasher speed), the effects of different microstructural elements, particularly air cells and fat globule clusters, on ice cream melt‐down properties were studied.Factors that caused an increase in shear stress within the freezer, namely increasing dasher speed and overrun, caused a decrease in air cell size and an increase in extent of fat destabilization. Increasing emulsifier content, especially of polysorbate 80, caused an increase in extent of fat destabilization. Both overrun and fat destabilization influenced drip‐through rates. Ice creams with a combination of low overrun and low fat destabilization had the highest drip‐through rates. Further, the amount of remnant foam left on the screen increased with reduced drip‐through rates. These results provide a better understanding of the effects of microstructure components and their interactions on drip‐through rate.Practical ApplicationsManipulating operating and formulation parameters in ice cream manufacture influences the microstructure (air cells, ice crystals, and fat globule clusters). This work provides guidance on which parameters have most effect on air cell size and fat globule cluster formation. Further, the structural characteristics that reduce melt‐down rate were determined. Ice cream manufacturers will use these results to tailor their products for the desired quality attributes.

ObjectiveTo describe a novel technique for the prevention of recurrent percutaneous endoscopic gastrostomy‐jejunostomy (PEG‐J) tube dislodgements and assess its feasibility and efficacy. This technique utilizes endoscopic suturing to secure the PEG‐J tube to the gastric wall.MethodsThis was a retrospective analysis of consecutive cases of recurrent PEG‐J tube dislodgements referred to a single endoscopist between June 2016 and June 2017, using an endoscopic suturing system to secure the PEG‐J tube directly to the gastric wall. Technical success rates, the procedure time and related adverse events were analyzed.ResultsThere were five patients in total (three females). The procedure was technically successful in all patients. There were no procedure‐related adverse events. The mean duration of follow‐up was 7.8 ± 5.1 months. Two patients had accidental dislodgement at 8.5 and 12 months, respectively. There were no other unintended dislodgements.ConclusionEndoscopic suturing with internal fixation of PEG‐J tube is a safe and feasible approach to manage recurrent unintended dislodgements.
An Investigation of Errors in Distributed Models' Stream Discharge Prediction Due to Channel Routing

Published: February 2018

AbstractOver the summer of 2015, the National Water Center hosted the National Flood Interoperability Experiment (NFIE) Summer Institute. The NFIE organizers introduced a national‐scale distributed hydrologic modeling framework that can provide flow estimates at around 2.67 million reaches within the continental United States. The framework generates discharges by coupling a given Land Surface Model (LSM) with the Routing Application for Parallel Computation of Discharge (RAPID). These discharges are then accumulated through the National Hydrography Dataset Plus stream network. The framework can utilize a variety of LSMs to provide the runoff maps to the routing component. The results obtained from this framework suggested that there still exists room for further enhancements to its performance, especially in the area of peak timing and magnitude. The goal of our study was to investigate a single source of the errors in the framework's discharge estimates, which is the routing component. The authors substitute RAPID which is based on the simplified linear Muskingum routing method by the nonlinear routing component the Iowa Flood Center have incorporated in their full hydrologic Hillslope‐Link Model. Our results show improvement in model performance across scales due to incorporating new routing methodology.
A fungal mock community control for amplicon sequencing experiments
Authors: Bakker Matthew G. 
Published: February 2018

AbstractMicrobial ecology has been profoundly advanced by the ability to profile complex microbial communities by sequencing of marker genes amplified from environmental samples. However, inclusion of appropriate controls is vital to revealing the limitations and biases of this technique. “Mock community” samples, in which the composition and relative abundances of community members are known, are particularly valuable for guiding library preparation and data processing decisions. I generated a set of three mock communities using 19 different fungal taxa and demonstrate their utility by contrasting amplicon sequencing data obtained for the same communities under modifications to PCR conditions during library preparation. Increasing the number of PCR cycles elevated rates of chimera formation, and of errors in the final data set. Extension time during PCR had little impact on chimera formation, error rate or observed community structure. Polymerase fidelity impacted error rates significantly. Despite a high error rate, a master mix optimized to minimize amplification bias yielded profiles that were most similar to the true community structure. Bias against particular taxa differed among ITS1 vs. ITS2 loci. Preclustering nearly identical reads substantially reduced error rates, but did not improve similarity to the expected community structure. Inaccuracies in amplicon sequence‐based estimates of fungal community structure were associated with amplification bias and size selection processes, as well as variable culling rates among reads from different taxa. In some cases, the numerically dominant taxon was completely absent from final data sets, highlighting the need for further methodological improvements to avoid biased observations of community profiles.
