Authors: Zhang Xiaodan , Gong Yanping , Peng Luluo 
Published: March 2020

PurposeOnline communities are increasingly important for organizations and marketers. However, the issue of how structural features of online communities affect consumers' behavioral engagement remains relatively unexplored. The purpose of this study is to examine how and why different types of interdependence within online communities (i.e. task/outcome interdependence) influence individual engagement in group activities, thereby providing insights regarding online community design.Design/methodology/approachTwo surveys were conducted with two online groups in China. One is a task-interdependent group from Douban Forum, and the other is an outcome-interdependent group from Sina Forum. A total of 159 valid responses from the task-interdependent group and 162 valid responses from the outcome-interdependent group were received. We analyzed the data using multivariate regression with Smart PLS and SPSS.FindingsThe results reveal that both task and outcome interdependence are positively related to individual behavioral engagement in online group behavior, and collective efficacy mediates the aforementioned effects. In addition, task complexity moderates the relationship between task interdependence and individual behavioral engagement; communication within group moderates the relationship between outcome interdependence and behavioral engagement, and the effect is mediated by collective efficacy.Originality/valueThis study is the first to investigate the role of an important factor of group structure, namely, interdependence, in fueling individual behavioral engagement in online communities. The results shed light on companies' design strategies to develop and retain online community members and also provide important insights for researchers interested in social network marketing.

Authors: Sohail Muhammad , Raza Rabeeah 
Published: March 2020

PurposeThe current determination is committed to characterize the boundary layer flow of Williamson nanofluid prompted by nonlinear strained superficial under heat and mass transport mechanisms. Buongiorno model is presented to view the influence of nanoparticles in fluid flow. Scrutiny has been conceded under the action of the transversely smeared magnetic field. Heat and mass relocation exploration are conducted in the companionship of radiation effects and actinic compensation.Design/methodology/approachSimilarity variable is designated to transmute nonlinear partial differential equations of conservation laws of mass, momentum, energy and species into ordinary dimensional expressions. These constitutive and complicated ordinary differential expressions assessing the flow situation are handled efficaciously by manipulating Runge–Kutta–Fehlberg procedure (RK-5) with shooting routine.FindingsThe graphical demonstration is deliberated to scrutinize the variation in velocity, temperature and concentration profiles with respect to flow regulating parameters. Numerical data are displayed through tables in order to surmise variation in skin friction coefficient and Nusselt number. The augmenting values of fluid parameter and magnetic parameter reduces the horizontal fluid velocity, whereas normal velocity upsurges for mounting values of stretching ratio parameter. Moreover, mounting values of radiation parameter and thermophoresis parameter upsurges the temperature profile, whereas, growing values of Prandtl number lessen the temperature field.Practical implicationsThe current exploration is used in many industrial and engineering applications in order to discuss the transport phenomenon.Originality/valueFlow over a nonlinear stretched surface has numerous applications in the industry. The present attempt examines the combined influence of various physical characteristics for the flow of Williamson fluid and no such attempt exist in the available literature.
Using Lean Six Sigma implied assumptions
Authors: Kane Victor E. 
Published: March 2020

PurposeThe intent of this work is to state the implied assumptions that define the setting for using a Lean Six Sigma (LSS) business strategy to conduct successful improvement projects.Design/methodology/approachThe execution of define, measure, analyze, improve, and control (DMAIC) phases utilizes philosophies, principles, concepts, success factors, and so forth for successful project completion. These traditional concepts form implied setting assumptions for conducting a successful project.FindingsTo establish the desired setting, it is necessary to state organizational performance modeling assumptions required for the use of many tools. Since Lean Six Sigma requires a unique organizational support structure, these assumptions must be added for completeness. Using the 15 collective assumptions is shown to provide benefits in four areas: training clarity, project assessment, leadership support, and theory foundation.Research limitations/implicationsAny list of assumptions is likely incomplete since project application settings are varied and some tools may have unique requirements.Practical implicationsThe most useful of the four benefits for practitioners is establishing a familiar framework for communicating with leadership. Management is trained to evaluate assumptions for any new business strategy such as an LSS process improvement initiative. A thoughtful leader will expect to evaluate LSS assumptions for a proposed project. Stating these implied assumptions will meet those expectations.Originality/valueMost of the stated assumptions exist in some implied form in the Lean Six Sigma literature. However, the familiar term “assumption” is not typically used in presenting Lean Six Sigma methodology. Using this traditional framework is shown to produce multiple benefits for learners and users.

AbstractCaveolae position CaV3.2 (T‐type Ca2+ channel encoded by the α‐3.2 subunit) sufficiently close to RyR (ryanodine receptors) for extracellular Ca2+ influx to trigger Ca2+ sparks and large‐conductance Ca2+‐activated K+ channel feedback in vascular smooth muscle. We hypothesize that this mechanism of Ca2+ spark generation is affected by age. Using smooth muscle cells (VSMCs) from mouse mesenteric arteries, we found that both Cav3.2 channel inhibition by Ni2+ (50 µM) and caveolae disruption by methyl‐ß‐cyclodextrin or genetic abolition of Eps15 homology domain‐containing protein (EHD2) inhibited Ca2+ sparks in cells from young (4 months) but not old (12 months) mice. In accordance, expression of Cav3.2 channel was higher in mesenteric arteries from young than old mice. Similar effects were observed for caveolae density. Using SMAKO Cav1.2−/− mice, caffeine (RyR activator) and thapsigargin (Ca2+ transport ATPase inhibitor), we found that sufficient SR Ca2+ load is a prerequisite for the CaV3.2‐RyR axis to generate Ca2+ sparks. We identified a fraction of Ca2+ sparks in aged VSMCs, which is sensitive to the TRP channel blocker Gd3+ (100 µM), but insensitive to CaV1.2 and CaV3.2 channel blockade. Our data demonstrate that the VSMC CaV3.2‐RyR axis is down‐regulated by aging. This defective CaV3.2‐RyR coupling is counterbalanced by a Gd3+ sensitive Ca2+ pathway providing compensatory Ca2+ influx for triggering Ca2+ sparks in aged VSMCs.

AbstractObjectivesIn patients at low clinical probability of acute aortic syndromes (AASs), decision on advanced aortic imaging is cumbersome. Integration of the aortic dissection detection risk score (ADD‐RS) with D‐dimer (DD) provides a potential pipeline for standardized diagnostic rule‐out. We systematically reviewed and summarized supporting data.MethodsCross‐sectional studies assessing integration of ADD‐RS with DD for diagnosis of AASs were identified on MEDLINE, EMBASE and Web Of Science databases. Two reviewers independently screened articles, assessed quality, and extracted data. The quality of design and reporting was evaluated with the QUADAS‐2 and STARD tools. Individual patient data were obtained, to allow analysis of both conventional (500 ng/mL) and age‐adjusted (DDage‐adj) DD cutoffs. Data were summarized for four diagnostic strategies combining ADD‐RS = 0 or ≤ 1, with DD < 500 ng/mL or < DDage‐adj. The statistical heterogeneity of the diagnostic variables was estimated with Higgins’ I2. Pooled values were calculated for variables showing nonsignificant heterogeneity.ResultsAfter screening of 680 studies, four articles (including a total of 3,804 patients) met inclusion criteria. One prospective study provided a low risk of bias/applicability concerns, while methodologic limitations were found in the other three retrospective studies. Statistical heterogeneity was negligible for sensitivity and negative likelihood ratio (LR) values and significant for specificity and positive LR values of all diagnostic strategies. Pooled sensitivity was 99.9% (95% confidence interval [CI] = 99.3% to 100%, I2 = 0) for ADD‐RS = 0 and DD < 500 ng/mL or < DDage‐adj, 98.9% (95% CI = 97.9% to 99.9%, I2 = 0) for ADD‐RS ≤ 1 and DD < 500 ng/mL, and 97.6% (95% CI = 96.3% to 98.9%, I2 = 0) for ADD‐RS ≤ 1 and DD < DDage‐adj.ConclusionsDespite methodologic limitations, integration of ADD‐RS = 0 or ≤ 1 with DD < 500 ng/mL shows negligible heterogeneity and consistently high sensitivity across studies, thus supporting reliability for diagnostic rule‐out of AASs. Data supporting ADD‐RS = 0 plus DDage‐adj appear preliminary and require further scrutiny.
At‐Large Elections and Minority Representation in Local Government
Authors: Abott Carolyn , Magazinnik Asya 
Published: March 2020

AbstractDespite a long history of legal challenges alleging that elections conducted at‐large suppress minority representation, this remains the dominant electoral system in local governments throughout the United States. Moreover, a large empirical literature remains divided over the present‐day impact of at‐large elections on the political success of underrepresented groups. We reconcile the competing findings in this literature by providing contingent, causal estimates of the effect of conversion from at‐large to ward elections on minority officeholding, using a novel identification strategy afforded by the California Voting Rights Act of 2001. We find a dramatic positive effect of conversion in districts where Latinos constitute a sufficiently large share of the voting population, and in large and residentially segregated districts. When these conditions are not satisfied, we consistently see null estimated effects.

Published: March 2020

AbstractExtracorporeal circulation is accompanied by changes in red blood cell morphology and structural integrity that affect cell function and survival, and thereby may contribute to the various side effects of heart–lung machine‐assisted surgery. Our main objectives were to determine the effect of circulation of red blood cells in a stand‐alone extracorporeal circuit on several parameters that are known to be affected by, as well as contribute to red blood cell aging. As a source of RBCs, we employed blood bank storage units of different ages. In order to assess the relevance of our in vitro observations for the characterization of extracorporal circulation technology, we compared these changes in those of patients undergoing extracorporeal circulation‐assisted cardiac surgery. Our results show that circulation in a heart–lung machine is accompanied by changes in red blood cell volume, an increase in osmotic fragility, changes in deformability and aggregation behavior, and alterations in the exposure of phosphatidylserine and in microvesicle generation. RBCs from 1‐week‐old concentrates showed the highest similarities with the in vivo situation. These changes in key characteristics of the red blood cell aging process likely increase the susceptibility of red blood cells to the various mechanical, osmotic, and immunological stress conditions encountered during and after surgery in the patient’s circulation, and thereby contribute to the side effects of surgery. Thus, aging‐related parameters in red blood cell structure and function provide a foundation for the validation and improvement of extracorporeal circulation technology.

AbstractMechanical small bowel obstruction (SBO) is a common postoperative complication, and most cases are caused by postoperative adhesions. We herein report a case of SBO with superior mesenteric vein occlusion caused by a metal staple after laparoscopic appendectomy. A 35‐year‐old Japanese woman presented to our department with severe upper abdominal pain and vomiting. She had undergone laparoscopic appendectomy using a linear stapler 7 years before. Abdominal CT showed mild small intestinal dilation with mesenteric edema and volvulus of the small bowel mesentery. Moreover, occlusion of the superior mesenteric vein was observed. Emergency exploratory laparoscopy revealed a strangulated SBO caused by a free unformed staple. The obstruction was released by a laparoscopic technique without bowel resection. The number of laparoscopic surgeries has recently been increasing, and complications specific to laparoscopic surgery have been recognized. All spilled and unformed staples should be removed to the greatest extent possible during laparoscopic operations.

AbstractIt is suggested that changes in echo intensity (EI) measured through ultrasound can detect muscle swelling. However, changes in EI have never been examined relative to a non‐exercise control following naïve exposure to exercise.PurposeExamine the changes in muscle thickness (MT), EI and isometric strength (ISO) before, immediately after, and 24, and 48 hr following biceps curls.MethodsTwenty‐seven non‐resistance‐trained individuals visited the laboratory four times. During visit 1, paperwork was completed and strength was measured. During visit 2, MT and ISO were measured before four sets of curls. Additional measures were taken immediately after exercise, as well as 24 and 48 hr post. Results are displayed as means (SD).ResultsFor MT, there was an interaction (p < .001). For the experimental condition, MT increased from pre [2.88(0.64) cm] to post [3.27(0.67) cm] and remained elevated 48 hr post. There were no changes for MT in the control arm. In the experimental arm, EI increased from pre [22.9(9.6) AU] to post [29.1(12.3) AU] exercise and returned to baseline by 24 hr. For the control condition, EI was different between pre [24.8(10.2) AU] and 48 hr [21.5(10.7) AU]. The change in EI in the experimental condition was greater than the control condition immediately post (p = .039) and at 48 hr (p = .016). For ISO, there was an interaction (p < .001). In the experimental condition, ISO decreased from pre [40.6(14.7) Nm)] to post [24.8(9.4) Nm] and remained depressed.ConclusionsExercise produced a swelling response, which was elevated 48 hr post. Despite a sustained increase in MT, EI was only elevated immediately post exercise.

AbstractPleomorphic fibromas are rare benign cutaneous neoplasms associated with deletion/loss of chromosomes 13q and 17p, where RB1 and TP53 are located, respectively. Herein, we report five cases of pleomorphic fibroma arising in patients with germline TP53 mutations, suggesting a potential link with Li‐Fraumeni syndrome. All three patients were female and young (mean age 27) with a strong personal and/or family oncologic history and confirmed pathogenic germline TP53 mutations. In two patients, multiple pleomorphic fibromas were diagnosed. Clinically, the lesions arose at various cutaneous sites and were small (≤2 cm) and raised (4/5). Histopathologically, the tumors were paucicellular, composed of atypical spindled to stellate cells with hyperchromatic and variably pleomorphic nuclei. Mitotic activity was exceedingly low, although rare atypical mitotic figures were seen in one case. Immunohistochemically, the tumor cells were diffusely positive for p16 (3/3) and showed loss of Rb expression (5/5). All cases showed aberrant p53 expression (overexpression in 4, complete loss in 1). The tumors have followed a benign clinical course with no evidence of progression or recurrence. In conclusion, the development of multiple pleomorphic fibromas in a young patient may be a clue to an underlying genetic cancer syndrome involving TP53.

AbstractBackgroundMetabolomics may represent an avenue for diagnosis of equine ascending placentitis.ObjectivesTo characterise the plasma metabolomic profile in healthy mares and mares with induced ascending placentitis, with the goal of identifying metabolites with potential clinical value for early diagnosis of placentitis.Study designControlled in vivo experiment.MethodsPlacentitis was induced in 10 late‐term pregnant pony mares viaStreptococcal equisubsp.zooepidemicusinoculation in five mares between days 285 and 290 of gestation, while five mares served as healthy controls. Repeated ultrasound examinations and jugular venipuncture were performed to obtain combined thickness of the uterus and placenta (CTUP) and plasma for NMR spectroscopy. Mares with increased CTUP were diagnosed with placentitis and treated in accordance with published therapeutic recommendations. NMR metabolomic analysis was performed to identify and quantify plasma metabolites at each time point. Concentrations were compared using ANOVA with repeated‐measures and PLS‐DA analysis.ResultsFour hours post‐inoculation, a significant increase was detected in the metabolites alanine, phenylalanine, histidine, pyruvate, citrate, glucose, creatine, glycolate, lactate and 3‐hydroxyisobutyrate that returned to baseline by 12 hours. On day 4, a significant reduction in the metabolites alanine, phenylalanine, histidine, tyrosine, pyruvate, citrate, glycolate, lactate and dimethylsulfone was seen in infected mares compared with controls.Main limitationsThere were small numbers of mares within groups. In addition, this work compares healthy animals with animals treated with multimodal therapeutics following diagnosis of placentitis without an untreated cohort.ConclusionsTwo phases of metabolite changes were noted after experimental infection: An immediate rise in metabolite concentration involved in energy, nitrogen, hydrogen and oxygen metabolism within 4 hours after inoculation that was followed by a decrease in metabolite concentrations involved in energy and nitrogen metabolism at 4 days, coinciding with ultrasonographic diagnosis of placentitis.
