The impact of enterprise social media platforms on knowledge sharing
Authors: Sun Yuan , Zhou Xinjie , Jeyaraj Anand , Shang Rong-An , Hu Feng 
Published: April 2019

PurposeEnterprise social media platforms (ESMPs) are web 2.0-based computer media tools that facilitate knowledge sharing by employees. The purpose of this paper is to outline the potential of ESMPs in both enabling and hindering knowledge sharing from the perspective of affordances.Design/methodology/approachThis is a conceptual paper which integrates the literature on ESMPs’ affordances and knowledge sharing.FindingsThis paper finds that prior research on affordances only considered artifacts without much attention on the role of individual goals and organizational context. ESMPs may both enable and hinder knowledge sharing by affording different user behaviors contingent on artifacts, individual goals and organizational context.Practical implicationsThe results of the paper will help managers and ESMPs designers to better understand the potential of ESMPs and pay attention to the positive and negative impacts of ESMPs in the process of knowledge sharing.Originality/valueThe paper derives a new categorization of affordances based on individual goals and organization context and portrays a model to describe how and when these affordances enable knowledge sharing through the development of transactive memory system and social capital and hinder knowledge sharing through overload, groupthink and privacy invasion.
How to achieve less emissions from freight transport in Sweden
Authors: Vierth Inge , Karlsson Rune , Linde Tobias , Cullinane Kevin 
Published: April 2019

Purpose
For the case of Sweden, this paper aims to determine how a range of different infrastructure fees and taxes influences modal split, port throughputs, air emissions, societal costs of greenhouse gas (GHG) emissions and air pollution, as well as logistics costs.

Design/methodology/approach
The Swedish national freight model is used to simulate a range of different proposed infrastructure fees, one by one and in combination. The volume of emissions of CO2-equivalents, NOx, SOx and PM under the different scenarios is calculated in both volume and monetary terms, by applying national emission factors and EU values for external costs.

Findings
Road user fees are calculated to have the largest impact on the modal split, GHG emissions and air pollution. The impact increases slightly when road user fees are combined with higher fees for sea and rail and/or gate fees in all Swedish ports. The imposition of gate fees over €30 per truck in all ports leads to shifts in cargo to land-based modes and to ports outside Sweden. The logistics costs in Sweden are found to be three to ten times higher than the benefits of reduced GHG emissions and air pollution, although other benefits to society need to be considered as well.

Research limitations/implications
Methods which attempt to evaluate alternative approaches to the internalisation of the external costs caused by transport need to be further developed. In particular, they need to encompass a more holistic perspective on “benefits to society”, other than merely reductions in GHG emissions and air pollution. To facilitate international acceptance and adoption, such methods require agreements to be reached on common definitions and routines.

Practical implications
The results can be used as basis for policy-making. They illustrate the environmental impacts of the fees and taxes one by one and in combination and to what extent these reinforce each other and should be co-ordinated.

Social implications
The outcomes are relevant to national and international policymakers and authorities, as well as port authorities, shippers and transport companies who need to determine unilateral strategies on how to reduce GHG emissions and air pollution, without undermining their wider business objectives.

Originality/value
The approach is original in facilitating the testing of policies which impact on the transport system and the environment across different dimensions. The work has additional value in informing policy because of its use of Sweden’s national freight transport model.
Trends in Agricultural Production Efficiency and their Implications for Food Security in Sub‐Saharan African Countries
Authors: Nsiah Christian , Fayissa Bichaka 
Published: April 2019

AbstractThe main objective of this paper is to estimate the agricultural sector production efficiency using data envelopment analysis based on a cross‐section of 49 African countries over the 1995–2012 period in order to analyze the determinants of annual efficiency scores to assess the impact of agricultural efficiency on food security. We find that agriculture aid, agricultural sector infrastructure, sanitation, and good governance serve the main drivers of agriculture efficiency and its growth. Our findings also suggest that a large portion of Africa's agricultural sector growth can be attributed to technical progress as opposed to efficiency changes.
Does carbon farming provide a cost‐effective option to mitigate GHG emissions? Evidence from China
Authors: Tang Kai , He Chuantian , Ma Chunbo , Wang Dong 
Published: April 2019

In this study, we apply a whole farm bioeconomic analysis to explore the changes in land use, farm practices and on‐farm greenhouse gas (GHG) emission under varying levels of agricultural greenhouse gas abatement incentives in the form of a carbon tax for a semi‐arid crop‐livestock farming system in China's Loess Plateau. Our results show that the optimised agricultural enterprises move towards being cropping‐dominated reducing on‐farm emission since livestock perform is the major source of emission. Farmers employ less oats‐based and rapeseed‐based rotations but more dry pea‐based rotations in the optimal enterprise mix. A substantial reduction in on‐farm greenhouse gas emission can be achieved at low cost with a small increase in carbon incentives. Our estimates indicate that crop‐livestock farmers in China's Loess Plateau may reduce their on‐farm GHG emission between 16.6 and 33 per cent with marginal abatement costs <￥100/t CO2e and ￥150/t CO2e in 2015 Chinese Yuan. The analysis implies that reducing greenhouse gas emission in China's semi‐arid crop‐livestock agriculture is potentially a low‐cost option.
From Global to Anthropocenic Assemblages: Re‐Thinking Territory, Authority and Rights in the New Climatic Regime
Authors: Matthews Daniel 
Published: April 2019

AbstractIn a widely read study, Saskia Sassen uses the territory, authority, rights (TAR) framework in order to analyse the transformation of social life in the West from ‘medieval’ to ‘global’ assemblages. In the context of rapid, planetary climatic change – with many claiming that we have entered a new and climatically uncertain epoch known as the Anthropocene – does the TAR framework provide the relevant conceptual resources required to understand the ‘Anthropocenic’ assemblages of the present? This article examines the limitations of Sassen's TAR framework, arguing that alterative theoretical resources are required in order to grasp the changing dynamics of social life in the context of the new climatic regime.

Published: April 2019

AbstractStudies focused on facial development during childhood have been conducted by means of 3D technology to provide modifications of anthropometric parameters. Facial mobility was also considered. This study proposed a 3D approach to facial growth changes. Facial surface data of 6 subjects were acquired in T1 (age 7–14 years) and after 7 years (T2), in rest position, and during voluntary movements, by a 3D laser scanner. Linear and angular measurements on rest position scans at T1 and T2 were compared. Each mimic scan was superimposed with the corresponding rest scan. Displacement of significant anthropometric points was measured for each facial gesture and at T1 and T2 statistically compared. Vertical measurements were those most influenced by aging. Some measurements of central facial area were consistent over time. The pattern of soft tissues displacement for each expression was consistent in T1 and T2. These results may be helpful for missing children identification.
Enhancement of Composition and Oxidative Stability of Chia (Salvia hispanica L.) Seed Oil by Blending with Specialty Oils

Published: April 2019

AbstractChia seed (Salvia hispanica L.) oil is mainly composed of ω‐3 fatty acids (61% to 70%). Despite being nutritionally favorable, higher amounts of polyunsaturated fatty acids result in poorer oxidative stability. Thus, the aim of this work was to produce edible vegetable oil blends rich in ω‐3 fatty acids and with greater oxidative stability than pure chia oil. Blending of chia with other specialty oils (walnut, almond, virgin, and roasted sesame oils) was assessed in the following respective proportions: 20:80, 30:70, and 40:60 (v/v). An accelerated storage test was conducted (40 ± 1 °C, 12 days). Primary and secondary oxidation products, free fatty acid content, antioxidant compounds, fatty acid composition, and induction time were determined. The blends presented higher oxidative stability indices than chia oil. Sensory analysis showed that, given a pure oil, judges did not identify statistically significant differences among the blends. The results suggest that blending of chia oil is an adequate alternative to obtain ω‐3‐enriched oils with higher oxidative stability indices.Practical ApplicationVegetable oil blending is a widely used practice in the edible oil industry to produce blended oils with enhanced stability and nutritional and sensory properties at affordable prices. The blends developed in this study from chia, sesame, walnut, and almond oils take advantage of the properties of each parent oil to yield products with improved oxidative stability, essential fatty acid presence, and sensory characteristics. To achieve a daily intake of 2.22 g/day of ω‐3 fatty acids as recommended by the Intl. Society for the Study of Fatty Acids and Lipids (ISSFAL), it is necessary to consume approximately one spoonful of the formulated mixtures.

Published: April 2019

AbstractTo effectively extract biogenic amines (BAs) from complex food matrices is an important issue. In this study, a stop‐and‐go‐extraction tip (StageTip)‐based method for simultaneous enrichment of six BAs including histamine, tyramine, putrescine, cadaverine, tryptamine, and β‐phenylethylamine in fish samples was developed and optimized. This StageTip‐based BAs extraction method required short extraction time, small sample size, and minimal consumption of organic solvents. In addition, an ultrahigh‐performance liquid chromatography coupled with triple quadrupole mass spectrometer was used to identify and quantify BAs without derivatization. Target recovery efficiencies of BAs from spiked fish samples ranged from 84% to 110%. Linear regression models were established to determine BAs in the range of 0.4 to 3.0 mg/L (R2 > 0.995). Good repeatability was obtained with relative standard deviation of peak areas (1.17 to 5.61%) and retention time (0.09 to 0.20%). High sensitivity was achieved for the detection of six BAs (0.064 to 1.00 ng/L for the limit of detection, 0.10 to 5 ng/L for the limit of quantification). The proposed method had an obvious advantage in the analysis of BAs in complex food matrices such as fish tissues since it could reflect the subtle distribution of BAs from one fish fillet.Practical ApplicationA StageTip‐based BAs enrichment combined with UPLC‐MS analysis method was developed and optimized, which was low‐cost, environmentally friendly, and with good analytical performances. As such, it has the potential to become a powerful tool for the analysis of BAs in different complex food matrices.

AbstractAimWe evaluated the effects of anti‐tumor necrosis factor (TNF) agents on health economics in ankylosing spondylitis (AS) patients.MethodsQUality of Life as Outcomes and its VAriation with DIsease States (QUO‐VADIS) was a prospective observational study following bio‐naïve AS patients (modified New York criteria) newly treated with golimumab (GLM) or infliximab (IFX; originator) in a clinical practice setting over 6 months. We evaluated use of concomitant medications, hospitalizations (in‐patient care or acute care) and visits in day care and out‐patient settings for the assessment of healthcare resource utilization (HCRU). Work productivity and activity impairment (WPAI) was assessed by the number of work days missed and quantifying absenteeism, presenteeism, work impairment, and activity using the WPAI instrument adapted to spondyloarthritis (WPAI‐SpA).ResultsNine hundred and sixty‐three patients received ≥1 dose of medication (78%, n = 751 GLM; 22%, n = 221 IFX). Mean age was 42.7 years; 61.4% were male. At baseline, the percentage of patients who reported hospitalizations (in‐patient care) was 13.6%, which decreased to 3.1% at 6 months, while out‐patient care at baseline was reported by 39.4% of patients, which decreased to 19.0% at 6 months. The percentage of patients receiving acute emergency at baseline reduced from 1.6% to 0.3% at 6 months. The mean (SD) number of days of work missed due to AS, was reduced from 6.3 (31.1) days at baseline to 2.7 (12.3) days at 6 months.ConclusionIn patients with AS newly treated with GLM or IFX for 6 months, HCRU was reduced and work productivity and activity increased.

AbstractObjectivesAxial spondyloarthritis (axSpA) is a chronic inflammatory arthritis involving the axial skeleton. Recent evidence suggests that microRNAs (miRNAs) play a critical role in ankylosing spondylitis (AS). In this study, we aimed to investigate whether miR‐17‐5p, miR‐27a, miR‐29a and miR‐126‐3p can be verified as potential biomarkers of axSpA.MethodsPeripheral blood mononuclear cell (PBMC) miRNA expression was evaluated by quantitative real‐time polymerase chain reaction among 43 patients with AS, 26 patients with non‐radiographic axSpA (nr‐axSpA) and 39 healthy controls. Detailed clinical histories were recorded and the correlation of miRNAs and clinical features were analyzed.ResultsWhen compared to controls, both patients with AS and nr‐axSpA had significantly higher expression levels of miR‐17‐5p, miR‐27a, miR‐29a and miR‐126‐3p. MiR‐27a was negatively correlated with Ankylosing Spondylitis Disease Activity Score as well as C‐reactive protein in patients with nr‐axSpA (r = −0.51, P < 0.01 and r = −0.42, P = 0.034 respectively). No other clinical features were found to correlate with the four miRNAs in patients with AS. Mir‐29a showed highest area under the curve with 0.952 and these four miRNAs may be potential biomarkers in patients with axSpA.ConclusionsWe reported elevated miR‐17‐5p, miR‐27a, miR‐29a and miR‐126‐3p expression in PBMCs of patients with axSpA, and the expression of these four miRNAs might be used as useful diagnostic markers in axSpA.

Published: April 2019

AbstractThis study assesses the ecological pressure exerted by changing land use and tenure on the Kitenden wildlife corridor, a critical cross‐border link between the Amboseli and Kilimanjaro national parks. The implications on viability of the two high‐value protected areas and their respective dispersal areas are both negative and serious. The extent of land use change and its impacts were assessed through household and vegetation surveys, while wildlife abundance was measured using transect walks. Approximately 30% of the study area has shifted from community to private land ownership over the last two decades. Except for baboon and vervet monkey, most wildlife avoided the cultivated area. Vegetation composition on the noncultivated area has been greatly altered by intense wildlife and livestock use, where mean herbaceous vegetation cover differed significantly among range‐plant categories (F3, 524 = 29.015, p < 0.05). The frequency of increaser I (21.4%) differs greatly from that of decreaser and forbs, at 8.3% and 7.4%, respectively Tree recruitment was low, with a significant difference in mean density among age classes (F2, 110 = 3.663, p < 0.05). Only through land leasing agreements between landowners and conservation organisations, and a widely supported land use plan, can the spread of cultivation be controlled and complete cessation of wildlife movement be prevented.

Published: April 2019

BackgroundColorectal cancer resection in the obese (OB) patients can be technically challenging. With the increasing adoption of laparoscopic surgery, the benefits remain uncertain. Hence, the aim of this study is to assess the short‐ and long‐term outcomes of laparoscopic compared to open colorectal cancer resection in the OB patients.MethodsA systematic review and meta‐analysis was performed according to the PRISMA guidelines. The outcome measures were 5‐year disease‐free survival, overall survival, circumferential resection margin and local and distant recurrence.ResultsA total of 20 studies were included, with a total number of 6779 participants, of whom 1785 (26.3%) were OB and 4994 (73.7%) were non‐obese (NOB) participants. The OB patients had higher R1 resection (OB 6.9% versus NOB 3.1%; P = 0.011) and lower mean number of lymph nodes harvested, with standard mean difference of −0.29; P = 0.023, favouring the NOB patients. However, there was no statistical difference for local (OB 2.8% versus NOB 3.4%) or distant recurrence (OB 12.9% versus NOB 15.2%) rate between the two cohorts. There was no difference in 5‐year disease‐free survival (OB 81% versus NOB 77.4%; odds ratio 1.25, P = 0.215) and overall survival (OB 89.4% versus NOB 87.9%; odds ratio 1.16, P = 0.572). Lastly, the OB group had higher mean total blood loss, total operative time and length of hospital stay when compared to NOB patients.ConclusionFrom a pooled non‐randomized study, laparoscopic colorectal cancer resection is safe in OB patients with equivalent long‐term outcomes compared to NOB patients. However, there is a higher morbidity rate with an increased demand on hospital resources for the OB cohort.

Published: April 2019

BackgroundNeck lumps can cause significant patient anxiety and benefit from a multidisciplinary diagnostic approach, with an ultrasound scan and fine needle aspirate. Internationally, ‘one‐stop’ clinics are used for the evaluation of neck lumps, to date no such clinic has been established in the New Zealand public hospital system. The objective of this study was to demonstrate the feasibility of a one‐stop diagnostic neck lump clinic (NLC), aiming for improved patient experience and efficiency.MethodsA consultant‐led pilot NLC was instituted with the involvement of a head and neck surgeon, radiologist and pathologist, allowing ultrasound scan and fine needle aspirate investigations to be performed simultaneously. A retrospective audit of patients in the 12 months prior to commencement of the NLC provided a comparison group.ResultsThe median number of clinic visits was 2 in the control group and 1 in the NLC (P < 0.001). Time from first specialist appointment to surgery was 192 days compared to 134.5 days for NLC (P = 0.057). Median time from first specialist appointment to treatment decision was 108.5 days compared to 0 days in the NLC (P < 0.001). Eighty‐eight percent of patients in the NLC were given a diagnosis at their first appointment. The median number of investigations required was 2 in the control group and 1 in the NLC (P < 0.001). Median cost per patient in the NLC was $794 and $1470 in the control group.ConclusionThis pilot trial demonstrates streamlined decision‐making and efficient utilization of services with a reduction in clinic visits, investigations and cost. High patient satisfaction was reported with this service.
Supporting families involved in court cases about life‐sustaining treatment: Working as academics, advocates and activists
Authors: Kitzinger Celia , Kitzinger Jenny 
Published: April 2019

AbstractThis article explores the links between our roles as academics, advocates, and activists, focusing on our research on treatment decisions for patients in vegetative and minimally conscious states. We describe how our work evolved from personal experience through traditional social science research to public engagement activities and then to advocacy and activism. We reflect on the challenges we faced in navigating the relationship between our research, advocacy, and activism, and the implications of these challenges for our research ethics and methodology—giving practical examples of how we worked with research participants, wrote up case studies and developed interventions into legal debates. We also address the implications of the impact agenda—imposed by the British Research Excellence Framework— for our actions as scholar‐activists. Finally, we ask how practicing at the borders of academia, advocacy, and activism can inform research—helping to contextualize, sensitize, and engage theory with practice, leading to a more robust analysis of data and its implications, and helping to ensure a dialogue between research, theory, lived experience, front‐line practice, law, and public policy.
