New centrality measure for nodes based on user social status and behavior on Facebook
Authors: Forouzandeh Saman , Sheikhahmadi Amir , Rezaei Aghdam Atae , Xu Shuxiang 
Published: May 2018

Purpose
This paper aims to analyze the role of influential nodes on other users on Facebook social media sites by social and behavioral characteristics of users. Hence, a new centrality for user is defined, applying susceptible-infected recovered (SIR) model to identify influence of users. Results show that the combination of behavioral and social characteristics would be determined the most influential users that influence majority of nodes on social networks.

Design/methodology/approach
In this paper, the authors define a new centrality for users, considering node status and behaviors. Thus, this node has a high level of influence. Node social status includes node degree, clustering coefficient and average neighbors’ node, and social status of node refers to user activities on Facebook social media website such as sending posts and receiving likes from other users. According to social status and user activity, the new centrality is defined. Finally, through the SIR model, the authors explore infection power of nodes and their influences of other node in the network.

Findings
Results show that the proposed centrality is more effective than other centrality approaches, infecting more nodes in social network. Another significant point in this research is that users who have high social status and activities on Facebook are more influential than users who have only high social status on the Facebook social media.

Originality/value
The influence of user on others in social media includes two key factors. The first factor is user social status such as node degree and clustering coefficient in social media graph and the second factor is related to user social activities in social media sites. Most centralities focused on node social status without considering node behavior. This paper analyzes the role of influential nodes on other users on Facebook social media site by social and behavioral characteristics of users.
From “clone towns” to “slow towns”: examining festival legacies
Authors: Duignan Michael B. , Kirby Seth I. , O’Brien Danny , Everett Sally 
Published: May 2018

Purpose
This paper aims to examine the role of grassroots (food) festivals for supporting the sustainability of micro and small producers, whilst exploring potential productive linkages between both stakeholders (festivals and producers) for enhancing a more authentic cultural offering and destination image in the visitor economy.

Design/methodology/approach
This paper is exploratory, qualitative and inductive. Evidence is underpinned by a purposive sample, drawing on ten in-depth interviews and 17 open-ended survey responses collected across 2014 and 2015 – drawing perspectives from traders participating in the EAT Cambridge festival.

Findings
This paper unpacks a series of serendipitous [as opposed to “strategic”] forms of festival and producer leveraging; strengthening B2C relationships and stimulating business to business networking and creative entrepreneurial collaborations. Positive emergent “embryonic” forms of event legacy are identified that support the longer-term sustainability of local producers and contribute towards an alternative idea of place and destination, more vibrant and authentic connectivity with localities and slower visitor experiences.

Originality/value
This study emphasises the importance of local bottom-up forms of “serendipitous leverage” for enhancing positive emergent “embryonic” legacies that advance “slow” tourism and local food agendas. In turn, this enhances the cultural offering and delivers longer-term sustainability for small local producers – particularly vital in the era of “Clone Town” threats and effects. The paper applies Chalip’s (2004) event leverage model to the empirical setting of EAT Cambridge and conceptually advances the framework by integrating “digital” forms of leverage.

Abstract

The increasing awareness that a fire regime that promotes biodiversity in one system can threaten biodiversity in another has resulted in a shift away from fire management based on vague notions of maximising pyrodiversity, towards determining the optimal fire regime based on the demonstrated requirements of target species.

We utilised a long‐running, replicated fire experiment on Melville Island, the largest island off the northern Australian coast, to test the importance of pyrodiversity for native mammals in a northern Australian savanna landscape. We first developed statistical models to determine how native mammal abundance has responded to nine years of experimentally‐manipulated fire frequency. Next, given each species' modelled response to fire frequency, we identified the level of pyrodiversity and optimal mix of fire frequencies that would be expected to maximise mammal diversity and abundance, and minimise extinction risk. This was done for both the entire mammal assemblage and for the mammal species currently declining on Melville Island.

Fire frequency was a significant predictor of abundance of the northern brown bandicoot Isoodon macrourus, black‐footed tree‐rat Mesembriomys gouldii, brush‐tailed rabbit‐rat Conilurus penicillatus, grassland melomys Melomys burtoni, pale field‐rat Rattus tunneyi, and mice/dunnarts but not for the common brushtail possum Trichosurus vulpecula.

The geometric mean abundance (GMA) of the entire mammal assemblage was positively associated with pyrodiversity, but peaked at an intermediate value. Hence, maximising pyrodiversity would reduce native mammal assemblage GMA below its potential maximum. The fire history for an area that maximised the entire native mammal assemblage GMA consisted of 57% long‐unburnt, 43% triennially burnt and <1% annually burnt. Pyrodiversity did not reduce the extinction risk, nor increase the GMA of declining mammals above that predicted in areas entirely annually or triennially burnt.

Synthesis and applications. We demonstrate a useful approach with which to develop fire management strategies based on the demonstrated requirements of target species. By comparing the optimal fire regime identified for the conservation of threatened species and that identified for the entire mammal assemblage, we demonstrate the flexibility of this approach to tailor fire management to address specific management priorities in other fire‐prone environments.
False advertising
Authors: Rhodes Andrew , Wilson Chris M. 
Published: May 2018

AbstractThere is widespread evidence that some firms use false advertising to overstate the value of their products. We consider a model in which a policy maker can punish such false claims. We characterize an equilibrium where false advertising actively influences rational buyers and analyze the effects of policy under different welfare objectives. We establish precise conditions where policy optimally permits a positive level of false advertising and show how these conditions vary intuitively with demand and market parameters. We also consider the implications for product investment and industry self‐regulation and connect our results to the literature on demand curvature.
How consumers respond to product certification and the value of energy information
Authors: Houde Sébastien 
Published: May 2018

AbstractI study how consumers respond to competing pieces of information that differ in their degree of complexity and informativeness. In particular, I study the choice of refrigerators in the United States, where a mandatory disclosure labelling program provides detailed information about energy cost, and a certification labelling program provides a simple binary‐star rating related to energy use. I find that the coarse certification may help some consumers to pay attention to energy information, but for others, it may crowd out efforts to process more accurate, but complex, energy information. The effect of the certification on overall energy use is thus ambiguous.

Published: May 2018

AbstractBackgroundInfliximab (IFX) carries potential risk of immunogenicity with the production of anti‐drug antibodies (ADA). ADA may belong to different isotypes and are usually measured by ELISA bridging assay. This test is not designed to detect IgG4 antibodies. The aim was to measure IgG4 anti‐IFX antibodies in a cohort of IFX‐treated patients and to evaluate their relationship with ADA and their clinical impact.MethodsAnti‐drug antibodies were detected using a bridging ELISA in the serum of 222 treated patients with different clinical outcomes to IFX. The same samples were analyzed for IgG4 anti‐IFX antibodies using an experimental ImmunoCAP assay with reduced serum IgG4 background levels. A longitudinal evaluation was performed in a subgroup of 38 patients to define the temporal evolution of IgG4 anti‐IFX.ResultsIgG4 anti‐IFX was found in 26.6% of patients. Eighty of 222 patients were ADA+ (36%) and the majority (57/80, 71.3%) had IgG4 anti‐IFX. Two IgG4‐positive but ADA‐negative patients were identified. IgG4 anti‐IFX levels correlated with the serum levels of ADA. IgG4 anti‐IFX was more common in both reactive and nonresponder patients than in tolerant/responder patients. Patients who had experienced IgE‐mediated reactions displayed significantly higher IgG4 anti‐IFX than IgE‐negative reactive patients. The majority of patients tested positive for IgG4 anti‐IFX after the first seven infusions.ConclusionsIgG4 anti‐IFX is common in treated patients and a large part of ADA producing patients produce IgG4 antibodies. The IgG4 anti‐IFX response does not prevent hypersensitivity reactions to IFX and correlates with the IgE anti‐IFX response.

Published: May 2018

AbstractIntroductionWomen with epilepsy have increased risk of complications in pregnancy with consequences for the mother and child. There are no studies on the influence of parity on complications in women with epilepsy.Material and methodsThis was a population‐based cohort study of all first and second births in the Medical Birth Registry of Norway 1999–2013. Risks were estimated and complication rates were compared in distinct women with epilepsy treatment categories. Outcomes were any hypertensive disorder, bleeding in pregnancy, induction of labor, cesarean section, postpartum hemorrhage and preterm birth.ResultsWe examined 361 588 women, of whom 211 248 had a second birth and 1074 (0.5%) of these had a diagnosis of epilepsy in both births. Of these, 406 used antiepileptic drugs in both pregnancies with lamotrigine (n = 118), carbamazepine (n = 83), valproate (n = 44) and levetiracetam (n = 27) being the four most common monotherapies. In the second birth, only risk of elective cesarean section (adjusted odds ratio 1.7, 95% confidence interval 1.4–2.0) and induction of labor (adjusted odds ratio 1.5, 95% confidence interval 1.2–1.7) were increased in women with epilepsy compared with women without epilepsy. There was a significant reduction in any hypertensive disorder, mild preeclampsia, emergency cesarean section, postpartum hemorrhage (>500 mL) and preterm birth from first to second birth in women with epilepsy, and also a significant increase in elective cesarean section.ConclusionsSecond births in women with epilepsy do not represent an increased risk of non‐iatrogenic complications, independent of antiepileptic drug use. There is a significant reduction in complications from first to second births in women with epilepsy.
Calciphylaxis in end‐stage liver and renal disease patients before and after transplant
Authors: Couri Thomas , Stier Matthew , Mikolajczyk Adam , Aronsohn Andrew 
Published: May 2018

AbstractCalciphylaxis is a rare vascular disorder characterized by calcification of arterioles which causes tissue inflammation and necrosis. It is associated with the metabolic disturbances seen in end‐stage renal disease (ESRD) and has also been described in patients with cirrhosis with preserved kidney function. Characteristic calciphylaxis lesions are black eschars surrounded by retiform purpura, and the gold standard for diagnosis is skin biopsy. Reported 1‐year mortality rates range between 45% and 80%. No treatment modality has been evaluated in a prospective randomized trial, and reports of treatment efficacy vary. Kidney transplant has been reported as a successful therapy for calciphylaxis; however, cases exist of the initial onset of calciphylaxis following kidney transplant as well as simultaneous liver‐kidney (SLK) transplant. The decision to maintain a patient with end‐stage renal and liver disease on the waiting list for SLK transplant following the onset of calciphylaxis must consider the high 1‐year mortality associated with this condition. More research is necessary to understand how to allocate donor allografts to manage patients with calciphylaxis and ESRD and/or cirrhosis effectively.
Prognosis and complications of immature teeth following lateral luxation: A systematic review
Authors: Clark Danielle , Levin Liran 
Published: May 2018

AbstractBackground/AimsLateral luxation injuries are a type of traumatic dental injury in which the tooth becomes displaced in the palatal/lingual or labial direction. This injury is common among children and can result in pulp canal obliteration or pulp necrosis. The objective of this systematic review was to gather existing data on lateral luxation injuries to immature teeth to evaluate their overall prognosis.MethodsA systematic search was conducted using Medline, Pubmed, Scopus, Lilacs, EMBASE and Cochrane databases in October 2017. Reference lists were also hand‐searched to identify additional literature. Prospective and retrospective observational studies were included. A total of 502 articles were screened and six articles were included in the study.ResultsPulp canal obliteration was the most frequent complication of immature teeth with lateral luxation (31.3%). This was followed by pulp necrosis (17.5%), inflammatory resorption (5.7%), and surface resorption (3.2%). Due to the heterogeneity of the studies, a meta‐analysis was not attempted. There was great variation in the reported outcomes among the studies.ConclusionAccurate prognosis evaluation of traumatic dental injuries is difficult due to the nature of current studies being retrospective or prospective cohort studies. Lateral luxation is a common traumatic dental injury and has life‐long concerns for a patient. It is important for future studies to report on the same outcomes to increase the quality of evidence regarding prognosis and treatment interventions, not only for lateral luxation injuries, but for all traumatic dental injuries.

Published: May 2018

AbstractIntroductionThis study explored stress predictors and the role of instructional methods and institutional differences in perceived stress levels amongst students at two Asian dental schools.Materials and MethodsAn anonymous questionnaire was distributed to undergraduate dental students at Tokyo Medical and Dental University (TMDU), Japan and the University of Medicine and Pharmacy (UMP), Hochiminh City, Vietnam in 2016. Data concerning the students' demographic information and grades, and responses to the Perceived Stress Scale (PSS) and Dental Environment Stress questionnaire (DES) were collected. The questionnaires were prepared in English and translated into Japanese and Vietnamese following a forward‐backward translation process.ResultsAltogether 684 students answered the questionnaire with a response rate of 97% for TMDU and 89% for UMP. The mean DES score of UMP students was significantly higher than TMDU (P < .001). TMDU students with dentistry as their first programme choice had significantly lower PSS and DES scores in several categories than other TMDU students, whilst UMP clinical students reported higher stress scores in several areas than UMP preclinical students.ConclusionHaving dentistry as their first choice of educational programme was a significant stress predictor for Japanese students whilst the clinical practicum was a significant stress predictor for Vietnamese students. Previous academic performance was not a significant stress predictor for students at either dental school. Dental students of an integrated, active‐learning curriculum reported lower stress levels than students of a traditional, discipline‐based curriculum.

AbstractObjectiveThe aim of this study was to evaluate the addition of cyclophosphamide in relapsed‐refractory multiple myeloma patients (RRMM) who experienced biochemical relapse or progression without CRAB, during treatment with lenalidomide and dexamethasone (Rd), to slow down the progression in active relapse.MethodsThis analysis included 31 patients with RRMM treated with Rd who received cyclophosphamide (CRd) at biochemical relapse. The CRd regimen was continued until disease progression.ResultsThe median number of CRd cycles administered was 8 (range: 1‐35). A response was observed in 9 (29%) patients. After a median observation time of 11 months, the median overall survival (OS) from the beginning of CRd was 17.7 months. The median progression‐free survival (PFS) from the beginning of CRd was 13.1 months.ConclusionThe addition of cyclophosphamide delays the progression in patients who present a biochemical relapse during Rd treatment. The response rate and the duration of PFS obtained with minimal toxicities and low costs induced us to setting up a randomized clinical trial.
Will climate change shift the lower ecotone of tropical montane cloud forests upwards on islands?

Published: May 2018

AbstractAimIsland tropical montane cloud forests (TMCFs) host a disproportionally high share of the global biodiversity and provide critical ecosystem services to vulnerable insular societies. However, this ecosystem is imperilled by anthropogenic impacts including climate change that might push TMCFs towards higher elevations. The elevation at which TMCFs start varies greatly among islands and may depend on topographically driven local climate, which may in turn be influenced by large‐scale climate. Thus, a necessary prerequisite to assessing the vulnerability of island TMCFs to climate change is to determine the role of island features versus regional climate in influencing local climate at the lower TMCF ecotone.LocationTropical islands.MethodsAn extensive literature review of the elevation at which island TMCFs start was undertaken. This elevation was modelled as a function of the altitude of the lifting condensation level (LCL) imposed by regional climate, island maximum elevation and upwind forest loss over the past 15 years.ResultsThe elevation of the lower TMCF boundary was found to have been reported for 93 islands worldwide. TMCFs starts from as low as 300 m on the small islands of Kosrae (Micronesia; maximum elevation = 628 m) and Aneityum (Vanuatu; 852 m) to a maximum of 1,600 m on the large islands of Cuba (1,974 m) and Hispaniola (3,175 m), providing a spectacular example of the ‘Massenerhebung effect’. Both regional climate (LCL altitude) and island features (maximum elevation) influenced the elevation of the lower TMCF boundary, and these variables together accounted for 79% of the variance.Main conclusionsOn islands, climate change is likely to cause significant but small upslope shifts of the LCL and subsequently of TMCF lower boundary elevation in the future (+4.4 m for each 1°C increase in temperature). TMCF clearing and biological invasions might appear to be more pressing threats.

Published: May 2018

AbstractThis article develops a framework for self‐regulated digital learning, which supports for self‐regulated learning (SRL) in e‐learning systems. The framework emphasizes 8 features: learning plan, records/e‐portfolio and sharing, evaluation, human feedback, machine feedback, visualization of goals/procedures/concepts, scaffolding, and agents. Each feature facilitates or supports one or more SRL skills, including planning, monitoring and evaluating learning, applying appropriate cognitive strategies, and setting standards of products or performance. The implementation in domain‐general and ‐specific systems as illustrated by web‐based inquiry and problem‐solving are discussed. Examples and learning effects are elicited from the literature to demonstrate various designs. Approaches for designing SRL systems, educational implications, and new directions for future research incorporating SRL into digital learning are presented.
“I Didn't Get to Say Good‐Bye… Didn't Get to Pet My Dogs or Nothing”: Bioecological Theory and the Indian Residential School Experience in Canada
Authors: Rose Hilary A. 
Published: May 2018

AbstractFor more than 100 years, Canada systematically attempted to assimilate Indigenous families, in part by separating children from their families and forcing them to attend residential schools. Non‐Indigenous Canadians are just now learning about the history of Canada's residential schools. Social scientists in Canada and elsewhere, including the United States (residential or boarding schools were not unique to Canada), are studying the impact of residential schools on adult survivors and their children, in particular by focusing on the intergenerational transmission of historical trauma. I propose a contextual model for family scholars to use in studying the long‐term and intergenerational effects of the residential schools: Urie Bronfenbrenner's bioecological theory with its emphasis on process–person–context–time. Although comprehensive contextual theories run the risk of limited precision, I conclude that Bronfenbrenner's theory does justice to a broad understanding of the residential schools and their intergenerational legacy, with important implications for future research.
The Central Roles of Race and Racism in Reframing Family Systems Theory: A Consideration of Choice and Time
Authors: James Anthony G. , Coard Stephanie Irby , Fine Mark A. , Rudy Duane 
Published: May 2018

AbstractThis article explores the central roles in family research and practice of race and racism in the reframing of family systems theory (FST) when applied to Black and/or African American families. Specifically, we discuss how current concepts of FST allow for an understanding of racial and ethnic socialization in the parent–child familial subsystem. We then theorize the potential reframing of FST to better accommodate race, ethnicity, and racism, and suggest an expansion of the theory by including the components of historical time and choice. We conclude with a brief discussion of the practical implications of our suggested expansion.
