Innovative adoption of hybrid supply chain strategies in urban local fresh food supply chain
Authors: Nakandala Dilupa , Lau H.C.W. 
Published: December 2018

PurposeThis paper aims to investigate the characteristics of demand and supply in relation to the real-world supply chain strategies of local urban fresh food supply chains (FFSC). It generates insights into how a range of strategies is adopted by urban retailer businesses in attempting to cater for the particular requirements of food-literate urban consumers and small-scale local growers.Design/methodology/approachUsing a multiple case study method, 12 urban local fresh food retailers in Sydney were studied and interview data were analyzed using thematic analysis.FindingsLocal fresh produce has characteristics of both functional and innovative products. Retailers with strong upstream and downstream collaborations adopt hybrid strategies for increased time efficiency and product variety. The dominance of strategies for time efficiency in downstream activities is aimed at maximising the product’s freshness and taste, while product range improvement strategies mean innovative retailers are working with growers to introduce new product types and offering new recipes to consumers that encourage a wider use of products. Urban retailers of local fresh produce leverage on their relationships with upstream and downstream supply chain entities in implementing hybrid strategies.ImplicationsPolicymakers will make use of the new knowledge generated about the real enablers of contemporary urban food systems in designing developmental policies; findings will inform urban FFSC retailers about how harmonious relationships can be leveraged for sustainability.Originality/valueThe study generates new knowledge on the implementation of a leagile approach by studying the adoption of innovative hybrid strategies by urban local FFSCs in relations to demand and supply characteristics and the utilization of strong vertical relationships in a short supply chain.

Published: November 2018

PurposeThe remarkable concept of entrepreneurial orientation (EO) has attracted scholars’ attention for its relevance to a firm’s performance. Based on bibliometric and distance-based visualization of similarities (VOS) analysis, the purpose of this paper is to outline a broad-spectrum perspective of the structure of research in EO across more than 20 years of publications, identifying the most prominent journals, authors and articles in this field.Design/methodology/approachThe paper uses the Web of Science Core Collection and the VOS viewer software. The analysis searches for all the documents connected to EO available in the database from 1976 to 2017. The graphical visualization maps the bibliographic data using both bibliographic coupling and co-citation data.FindingsEntrepreneurship Theory and Practice Journal,Journal of Business VenturingandFamily Business Revieware the most relevant journals in the field. Among the many important authors in the EO literature, key contributors are Lumpkin, Payne, Short, Covin, Dess and Wiklund. Three different streams of research are linked to the EO concept; strategy and entrepreneurship, family business and miscellaneous work in psychometrics, methods, marketing and knowledge/capability-based approaches to organizations.Originality/valueThis paper contributes to EO research by providing a global perspective on the concept’s investigation, using bibliometric data and graphical networks.
Heterogeneous effects of adolescent violent victimization on problematic outcomes in early adulthood*
Authors: Turanovic Jillian J. 
Published: December 2018

AbstractViolent victimization—particularly when it happens to young people—can inflict a wide array of negative consequences across the life course. Nevertheless, some victims are more likely to suffer these consequences than others, and we do not have a very good understanding of why that is. One promising avenue of research is to examine how individuals’ differential risks of being victimized affect the extent to which they experience negative outcomes. By using propensity score matching and data from the National Longitudinal Study of Adolescent to Adult Health (N = 8,323), in this study I estimate the heterogeneous effects of adolescent violent victimization on several problematic outcomes in early adulthood (violent and property offending, subsequent violent victimization, depressive symptoms, hard drug use, and low educational attainment). Individuals’ differential risks of adolescent violent victimization are estimated with a host of personal, social, and contextual factors, including prior experiences with crime and violence. The results show that the consequences of adolescent victimization in early adulthood are more pronounced for youth with the lowest risks of being victimized. These findings have important implications for theory, research, and practice, and they emphasize that the consequences of victimization cannot be understood separately from the sources of victimization.

Published: December 2018

AbstractIntroductionMagnetic Resonance Imaging (MRI) provides excellent soft tissue definition of pelvic tumours and organs. The aim of this study was to quantify differences in delineated clinical target volumes (CTVs) between computed tomography (CT) and MRI.MethodsTwenty patients with locally advanced gynaecological malignancies were recruited. Patients underwent dedicated MRI simulation following CT simulation. Four clinicians independently contoured each CT and MRI. CTV structures were contoured using the Radiation Therapy Oncology Group (RTOG) guidelines and lymph node CTV (LN‐CTV) according to published guidelines. Interobserver variability was analysed using the dice similarity coefficient (DSC) and mean absolute surface distance (MASD).ResultsGross tumour volume delineation was more consistent on MRI compared to CT, the DSC improved from 0.77 on CT to 0.81 on MRI, P < 0.01. GTV volumes were significantly smaller on MRI compared to CT (MRI 92 cc vs. CT 117 cc, P < 0.01). The LN‐CTV and combined CTV volumes were both significantly smaller on MRI compared to CT (LN‐CTV: MRI 324 cc vs CT 354 cc, P < 0.01 and combined CTV: MRI 560 cc vs CT 600 cc, P < 0.01). The LN‐CTV DSC was 0.75 for both MRI and CT, and the combined CTV DSC was 0.81 for MRI and 0.80 for CT, P = 0.27. Vagina and parametria volumes exhibited more variability compared to other structures.ConclusionsMagnetic Resonance Imaging contouring resulted in smaller and more consistently delineated volumes when compared to CT for most CTV structures. An MRI contouring atlas is provided to complement the existing RTOG contouring guidelines.
Inferring community assembly processes from macroscopic patterns using dynamic eco‐evolutionary models and Approximate Bayesian Computation (ABC)
Authors: Pontarp Mikael , Brännström Åke , Petchey Owen L. 
Published: December 2018

Abstract

Statistical techniques exist for inferring community assembly processes from community patterns. Habitat filtering, competition, and biogeographical effects have, for example, been inferred from signals in phenotypic and phylogenetic data. The usefulness of current inference techniques is, however, debated as a mechanistic and causal link between process and pattern is often lacking, and evolutionary processes and trophic interactions are ignored.

Here, we revisit the current knowledge on community assembly across scales and, in line with several reviews that have outlined challenges associated with current inference techniques, we identify a discrepancy between the current paradigm of eco‐evolutionary community assembly and current inference techniques that focus mainly on competition and habitat filtering. We argue that trait‐based dynamic eco‐evolutionary models in combination with recently developed model fitting and model evaluation techniques can provide avenues for more accurate, reliable, and inclusive inference. To exemplify, we implement a trait‐based, spatially explicit eco‐evolutionary model and discuss steps of model modification, fitting, and evaluation as an iterative approach enabling inference from diverse data sources.

Through a case study on inference of prey and predator niche width in an eco‐evolutionary context, we demonstrate how inclusive and mechanistic approaches—eco‐evolutionary modelling and Approximate Bayesian Computation (ABC)—can enable inference of assembly processes that have been largely neglected by traditional techniques despite the ubiquity of such processes.

Much literature points to the limitations of current inference techniques, but concrete solutions to such limitations are few. Many of the challenges associated with novel inference techniques are, however, already to some extent resolved in other fields and thus ready to be put into action in a more formal way for inferring processes of community assembly from signals in various data sources.
Association between TNF‐α polymorphisms and the risk of upper gastrointestinal bleeding induced by aspirin in patients with coronary heart disease
Authors: Wang Tai‐ping 
Published: December 2018

AbstractObjectiveTo investigate the correlation of tumor necrosis factor α (TNF‐α) polymorphisms with upper gastrointestinal bleeding (UGIB) induced by enteric‐coated aspirin in coronary heart disease (CHD) patients.MethodsIn total, 154 CHD patients taking enteric‐coated aspirin were enrolled in this study. Patients were divided into the UGIB group (n = 57) and non‐UGIB group (n = 97) based on the presence or absence of signs of UGIB, respectively. TNF‐α polymorphism (‐857C > T, ‐863C > A, and ‐1031T > C) genotyping was performed using polymerase chain reaction (PCR) amplification with sequence‐specific primers (PCR‐SSP).ResultsPatients who had the CC genotype and C allele of ‐1031T > C exhibited a significantly increase risk of UGIB after receiving enteric‐coated aspirin (CC vs. TT: odds (OR) (95% confidence interval (CI)): 7.568 (1.527–37.49), P = 0.005; C vs. T: OR (95% CI): 1.852 (1.036–3.312), P = 0.036). Patients who had CA and CA + AA genotypes and the A allele of ‐863C > A also exhibited an increased risk of aspirin‐induced UGIB (CA vs. CC: OR (95% CI): 2.415 (1.143–5.101), P = 0.019: CA + AA vs. CC: OR (95% CI): 2.218 (1.123–4.381), P = 0.021; A vs. C: OR (95% CI): 1.788 (1.039–3.078), P = 0.035). However, the TNF‐α ‐857 C > T polymorphism was unrelated to the induction of UGIB by enteric‐coated aspirin in CHD patients (P > 0.05). In addition, the haplotypes of CCC (‐1031T > C, ‐863C > A, and ‐857C > T) markedly reduced the risk of aspirin‐induced UGIB in CHD patients.ConclusionTNF‐α ‐863A and ‐1031C increased the risk of UGIB induction by enteric‐coated aspirin in CHD patients, whereas TNF‐α ‐857C > T was not correlated with the UGIB risk.
Commentary: Sports participation at 4 years old? Thoughts on mental health‐risk trajectories in the longitudinal study of Australian children – a commentary on Vella et al. (2018)
Authors: Crowell Judith A. 
Published: December 2018

Vella and colleagues (this issue) report on children in the kindergarten cohort of the Longitudinal Study of Australian Children (LSAC) study, using predictors from age 4 years to identify six trajectories of mental health risk from ages 4–12. Somewhat surprisingly, they find that among some predictable candidates for risk, such as sex and family income, that sports participation at age four emerges as a novel predictor of low difficulty with respect to mental health trajectories across the next 8 years. Is this a case of mens sana in corpore sano? Or is sports participation, that is, swimming, dancing, gymnastics, and team sports, a proxy for other factors? What can the various predictors and the trajectories of mental health risk from this longitudinal study tell us about interventions to reduce risk?
Use of IL‐1 β, IL‐6, TNF‐α, and MMP‐8 biomarkers to distinguish peri‐implant diseases: A systematic review and meta‐analysis
Authors: Ghassib Iya , Chen Zhaozhao , Zhu Juanfang , Wang Hom‐Lay 
Published: December 2018

AbstractObjectiveTo investigate the use of peri‐implant crevicular fluid (PICF) interleukin‐1β (IL‐1β), IL‐6, tumor necrosis factor‐α (TNF‐α), and matrix metalloproteinase‐8 (MMP‐8) biomarkers in distinguishing between healthy implants (H), peri‐implant mucositis (MU), and peri‐implantitis (PI).Material and MethodsElectronic using three databases (Pubmed, EMBASE, and Cochrane) and manual searches were conducted for articles published up to March 2018 by two independent calibrated reviewers. Meta‐analyses using a random‐effects model were conducted for each of the cytokines; IL‐1β, IL‐6, and TNF‐α, to analyze standardized mean difference (SMD) between H and MU, MU and PI, H and PI with their associated 95% confidence intervals (CI). Qualitative assessment of MMP‐8 was provided consequent to the lack of studies that provide valid data for a meta‐analysis.ResultsNineteen articles were included in this review. IL‐1β, IL‐6, and TNF‐α, levels were significantly higher in MU than H groups (SMD: 1.94; 95% CI: 0.87, 3.35; P < .001, SMD: 1.17; 95% CI: 0.16, 3.19; P = .031 and SMD: 3.91; 95% CI: 1.13, 6.70; P = .006, respectively). Similar results were obtained with PI compared to H sites (SMD: 2.21, 95% CI: 1.32, 3.11; P < .001, SMD: 1.72; 95% CI: 0.56, 2.87; P = .004 and SMD: 3.78; 95% CI: 1.67, 5.89; P < .001, respectively). IL‐6 was statistically higher in PI than MU sites (SMD = 1.46; 95% CI: 0.36, 2.55; P = .009); while IL‐1ß increase was not significant. Despite absence of meta‐analysis, MMP‐8 show to be a promising biomarker in detection of PI in literature.ConclusionWithin the limitations of this study, pro‐inflammatory cytokines in PICF, such as IL‐1ß and IL‐6, can be used as adjunct tools to clinical parameters to differentiate H from MU and PI.

Published: December 2018

AimThe primary aim of this review is to evaluate the evidence for pain prevalence in children and young adults with cerebral palsy. Secondary aims are to identify pain characteristics and types of pain measurement used in this population.MethodOvid MEDLINE, Embase, CINAHL Plus, and PubMed were searched in October 2016 and updated in November 2017. Two authors independently screened studies according to Preferred Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines. Pain outcomes were categorized within a biopsychosocial pain framework, with pain prevalence extracted for all recall periods and measurement types.ResultsOne hundred and six publications from 57 studies met inclusion criteria. Pain prevalence varied widely from 14 per cent to 76 per cent and was higher in females, older age groups, and those classified within Gross Motor Function Classification System level V. Pain was most frequent in the lower limbs, back, and abdomen and associated with reduced quality of life or health status. The influence of pain on psychological functioning, interference, and participation was inconclusive.InterpretationVariation exists in reported pain prevalence because of sampling bias, inconsistent measurement, varying recall periods, and use of different participant age ranges.What this paper adds

Pain prevalence varies from 14 per cent to 76 per cent in children and young adults with cerebral palsy.

Pain is more prevalent in females, older age groups, and children in Gross Motor Function Classification System level V.

Published: December 2018

AimWe explored factors associated with pain and its severity in a population cohort of young people with bilateral cerebral palsy, comparing parent/carer and young people self‐reports.MethodOf 278 survivors (mean age 16y 8mo, SD 1y 4mo, range 13y 8mo–19y 3mo) from the South Thames in the Study of Hips and Physical Experience cohort of 338 young people with bilateral cerebral palsy, 212 parents/carers and 153 young people completed questionnaires on the presence, severity, timing, site, associated factors, impact, and treatment of pain.ResultsSeventy per cent of parents/carers reported pain within 3 months, 59% the previous week, and 50% the previous day with 56% reporting ‘regularly experienced’. Of young people able to do so, 63% reported pain within 3 months, 50% the previous week, and 42% the previous day, with 48% reporting regular pain. There was strong agreement between the parent/carer and young people, reporting pain severity over the previous 3 months. Pain severity was associated with increased motor impairment and comorbidity, particularly constipation, spasticity, equipment use, and higher emotional score, but not sex, intellectual disability, speech, or maternal education. Multiple sites of musculoskeletal pain were reported in two‐thirds of individuals. Pain was associated with voluntary movement in individuals with less motor impairment and with being moved in those with severe motor impairment. Greater pain severity had a negative effect on both physical and psychological quality of life.InterpretationIncreasing awareness of the comorbidities in cerebral palsy may aid effective treatment, reducing pain experienced by young people with cerebral palsy.What this study adds

Regular moderate or severe pain is reported in young people with bilateral cerebral palsy (CP) in all Gross Motor Function Classification System levels.

Pain is reported more frequently in young people who are non‐ambulant.

General ill health is strongly associated with severity of pain after controlling for severity of CP, especially constipation.

Pain occurs most often in ambulant young people during voluntary activity and in those who are non‐ambulant when being moved.

There is strong agreement between parents/carers and young people about pain presence and severity.
Childhood neurodevelopment after prescription of maintenance methadone for opioid dependency in pregnancy: a systematic review and meta‐analysis
Authors: Monnelly Victoria J , Hamilton Ruth , Chappell Francesca M , Mactier Helen , Boardman James P 
Published: December 2018

AimTo systematically review and meta‐analyse studies of neurodevelopmental outcome of children born to mothers prescribed methadone in pregnancy.MethodMEDLINE, Embase, and PsycINFO were searched for studies published from 1975 to 2017 reporting neurodevelopmental outcomes in children with prenatal methadone exposure.ResultsForty‐one studies were identified (2283 participants). Eight studies were amenable to meta‐analysis: at 2 years the Mental Development Index weighted mean difference of children with prenatal methadone exposure compared with unexposed infants was −4.3 (95% confidence interval [CI] −7.24 to −1.63), and the Psychomotor Development Index weighted mean difference was −5.42 (95% CI −10.55 to −0.28). Seven studies reported behavioural scores and six found scores to be lower among methadone‐exposed children. Twelve studies reported visual outcomes: nystagmus and strabismus were common; five studies reported visual evoked potentials of which four described abnormalities. Factors that limited the quality of some studies, and introduced risk of bias, included absence of blinding, small sample size, high attrition, uncertainty about polydrug exposure, and lack of comparison group validity.InterpretationChildren born to mothers prescribed methadone in pregnancy are at risk of neurodevelopmental problems but risk of bias limits inference about harm. Research into management of opioid use disorder in pregnancy should include evaluation of childhood neurodevelopmental outcome.What this paper adds

Children born to opioid‐dependent mothers prescribed methadone are at risk of neurodevelopmental impairment.

Exposed infants have lower Mental Development Index and Psychomotor Development Index scores than unexposed children.

Atypical visual evoked potentials, strabismus, and nystagmus have increased prevalence.

Estimates of impairment may be biased by intermediate to poor quality evidence.

Published: December 2018

Abstract

Given the ongoing decline of many species, it is important to perform multifactorial analyses of conservation status and to assess the effects of species extinction on ecosystem services.

In this study, we used long‐term surveys to assess the influence of habitat change, landscape alteration and invasive species on extinction risk of the native crayfish Austropotamobius pallipes. We reviewed the existing literature to assess which ecosystem services are threatened by local extinction of A. pallipes and replacement with alien crayfish.

We sampled 196 streams and wetlands in northern Italy. Of these, 117 received multiple surveys over a 13‐year period (2004–2017), thus allowing accurate measurement of extinction rate.

Thirty‐four percent of A. pallipes populations underwent extinction between 2004 and 2017. The occurrence of alien crayfish in the catchment basin and urban growth in the landscape surrounding streams were associated with A. pallipes extinction. The probability of persistence was significantly higher in populations close to stream springs and with physical barriers (especially waterfalls) separating them from basins with alien crayfish.

Extinction of native crayfish alters community structure and impairs regulating services such as detrital breakdown and pest regulation. Replacement by alien crayfish (Procambarus clarkii and Faxonius limosus) also threatens supporting and regulating services by altering nutrient cycling, food webs, sediments and erosion.

The implementation of management practices that control river connectivity using selective barriers is needed to prevent further local extinction of native species. Integrating information on extinction with knowledge of impacts on ecosystem services is essential in developing more effective conservation policies.
