Published: February 2018

PurposeThe aim of this paper is to provide a comprehensive and detailed review of the state-of-the-art mechanisms of knowledge sharing in the education field as well as directions for future research.Design/methodology/approachIn the current study, a systematic literature review until June 2017 is presented, which has been on the education’s mechanisms of knowledge sharing. The authors identified 237 papers, which are reduced to 71 primary studies through the paper selection process.FindingsBy providing the state-of-the-art information, the challenges and issues, this survey will directly support academics, researchers and practicing professionals in their understanding of knowledge sharing developments in education.Research limitations/implicationsThere are several limitations in this study. First, this study limited the search for articles to Google scholar and four online databases. There might be other academic journals, which may be able to provide a more comprehensive picture of the articles related to the knowledge sharing in education. Second, non-English publications were excluded from this study. The authors believe research regarding the application of knowledge sharing techniques have also been discussed and published in other languages. In addition, more studies need to be carried out using other methodologies such as interviews.Originality/valueThe paper presents a comprehensive structured literature review of the articles’ mechanisms of knowledge sharing in the education field. The paper’s findings can offer insights into future research needs.
Providing telecare for older adults: understanding the care navigators’ experience
Authors: Naick Madeline 
Published: February 2018

Purpose
The provision of telecare for older adults in England is increasingly being facilitated by care navigators in the non-statutory sector. The purpose of this paper is to explore the experiences of care navigators when assessing older adults for telecare and to understand what contextual and organisational factors impact on their practice.

Design/methodology/approach
A purposeful sample of care navigators and telecare installers was selected. Care navigators were recruited from five non-statutory organisations. In order to provide an insight into telecare provision by this sector, telecare installers were also recruited. Semi-structured interviews were conducted with 11 participants covering: role, training, assessment, reviews, installation, suitability, impact, aims, outcomes, and organisational structure. Interview data were analysed using the framework approach.

Findings
Five main themes emerged from the analysis: responsiveness, autonomy, knowledge exchange, evolving practice, and sustaining performance.

Research limitations/implications
This study included a small sample, and was only based in one local authority, focusing on the experience of care navigators in only one sector.

Practical implications
The findings suggest that strategic placement of care navigators could support the demand for telecare assessment to facilitate discharges from hospital. This study highlights the perception of home assessment as a gold standard of practice for care navigators. In order to develop a more sustainable model for care navigators’ capacity to work within hospital teams and provide home assessments needs further consideration.

Originality/value
This study is one of the first to explore the role of the care navigator and their involvement in the provision of telecare for older adults.
Heterocarpy in Salvia roemeriana (Lamiaceae)
Authors: Zona Scott , Harris Brittany 
Published: February 2018

AbstractAlthough Salvia roemeriana has long been known to produce both chasmogamous and cleistogamous flowers, the mericarps resulting from those flowers have received little attention. We germinated seeds from chasmogamous and cleistogamous flowers, recorded germination times, and fit time‐to‐germination, three‐parameter log‐logistic regressions to analyze differences in germination progress. Additionally, we compared the mass and size of mericarps from both kinds of flowers. Our results show that the mericarps produced from chasmogamous flowers are larger and heavier than those from cleistogamous flowers. In addition, seeds from chasmogamous flowers had a longer dormancy than those from cleistogamous flowers. This is the first report of heterocarpy in Salvia and in the family Lamiaceae. Together, cleistogamy and heterocarpy are a multiple strategy that may be advantageous in heterogeneous environments.
Does Intensive Tillage Enhance Productivity and Reduce Risk Exposure? Panel Data Evidence from Smallholders’ Agriculture in Ethiopia
Authors: Abro Zewdu Ayalew , Jaleta Moti , Teklewold Hailemariam 
Published: February 2018

AbstractWe analyse the impact of intensity of tillage on wheat productivity and risk exposure using panel household‐plot level data from Ethiopia. In order to control for selection bias, we estimate a flexible moment‐based production function using an endogenous switching regression treatment effects model. We find that tillage has a complementary impact on productivity and risk exposure. As the intensity of tillage increases, productivity increases and farmers’ exposure to risk declines. Our results suggest that smallholder farmers use tillage as an ex‐ante risk management strategy. The main policy implication of this study is that the opportunity cost of switching to reduced tillage in wheat production seem rather high unless farmers are supported by appropriate incentive schemes.
Consumer Demand for Genetically Modified Rice in Urban China
Authors: Zheng Zhihao , Henneberry Shida R. , Sun Chuanzhong , Nayga Rodolfo M. 
Published: February 2018

AbstractWe investigate consumer demand for genetically modified (GM) rice in urban China, using a relatively large survey of urban consumers in 2013 and the contingent valuation method. Our results show that respondents discount their WTP for first, second and third generation of GM rice by 31%, 34% and 36%, respectively, compared with non‐GM rice, indicating substantial aversion to GM rice by Chinese consumers. The level of consumers’ subjective knowledge of GM rice has a significantly negative impact on their WTP for GM rice, implying that GM rice in China has become a ‘special food’ with an unreliable image.

AbstractThe Atlantic bluefin tuna is a highly migratory species emblematic of the challenges associated with shared fisheries management. In an effort to resolve the species’ stock dynamics, a genomewide search for spatially informative single nucleotide polymorphisms (SNPs) was undertaken, by way of sequencing reduced representation libraries. An allele frequency approach to SNP discovery was used, combining the data of 555 larvae and young‐of‐the‐year (LYOY) into pools representing major geographical areas and mapping against a newly assembled genomic reference. From a set of 184,895 candidate loci, 384 were selected for validation using 167 LYOY. A highly discriminatory genotyping panel of 95 SNPs was ultimately developed by selecting loci with the most pronounced differences between western Atlantic and Mediterranean Sea LYOY. The panel was evaluated by genotyping a different set of LYOY (n = 326), and from these, 77.8% and 82.1% were correctly assigned to western Atlantic and Mediterranean Sea origins, respectively. The panel revealed temporally persistent differentiation among LYOY from the western Atlantic and Mediterranean Sea (FST = 0.008, p = .034). The composition of six mixed feeding aggregations in the Atlantic Ocean and Mediterranean Sea was characterized using genotypes from medium (n = 184) and large (n = 48) adults, applying population assignment and mixture analyses. The results provide evidence of persistent population structuring across broad geographic areas and extensive mixing in the Atlantic Ocean, particularly in the mid‐Atlantic Bight and Gulf of St. Lawrence. The genomic reference and genotyping tools presented here constitute novel resources useful for future research and conservation efforts.
Treatment of semen samples with α‐chymotrypsin alters the expression pattern of sperm functional proteins—a pilot study
Authors: Panner Selvam M. K. , Agarwal A. , Sharma R. , Samanta L. 
Published: February 2018

SummarySemen hyperviscosity delays the liquefaction of semen sample and is subjected to limited proteolysis by addition of α‐chymotrypsin to reduce the viscosity. α‐Chymotrypsin is a proteolytic enzyme involved in degradation of the proteins and polypeptides. Even though α‐chymotrypsin improves the handling of hyperviscous samples, its effect on the sperm proteins is not clear. This study was aimed to evaluate the alteration in the expression of sperm functional proteins in samples treated with α‐chymotrypsin. Among all the proteins examined in both donor and patient samples, HSPA2 (70 KDa), BAG6 (150 KDa), HIST1H2BA (14 KDa), SPA17 (17 KDa formed after cleavage of C‐terminal calmodulin‐binding domain), and OXPHOS complexes were undetectable in α‐chymotrypsin‐treated samples, while the expression of the native SPA17 (20 KDa) was significantly decreased in the α‐chymotrypsin‐treated samples in comparison with controls. The use of α‐chymotrypsin for liquefaction of hyperviscous samples degrades functional proteins of spermatozoa. Intracellular proteins, such as OXPHOS complexes and HIST1H2BA, and sperm surface proteins (HSPA2, BAG6, and SPA17) were degraded in all treated samples. Whether treatment of samples with α‐chymotrypsin affects the global proteomic outcome is unclear. More in‐depth calibration studies are required to determine the appropriate concentration of α‐chymotrypsin for processing hyperviscous semen samples without compromising its protein expression and function. Similarly, the effects of altered protein function on assisted reproductive techniques (ART), such as intrauterine insemination (IUI) and in vitro fertilization (IVF) outcome, are not known and require further research.

AbstractPurposeIdiopathic intracranial hypertension (IIH) is characterized by raised intracranial pressure (ICP), normal cerebrospinal composition and exclusion of alternative causes to increased ICP. The aim of this study was to evaluate long‐term visual outcome in a Danish population of IIH patients.MethodsRetrospective chart review of 41 women diagnosed with IIH between June 2007 and March 2013. Best‐corrected visual acuity (BCVA), colour vision, grade and type of visual field (VF) defects and grade of papilloedema according to the Modified Frisén Score were recorded at baseline visit (V0), 2–6 months (V1) and 13 months follow‐up visit (V2) from time of diagnosis.ResultsBest‐corrected visual acuity (BCVA) was reduced in 25% of eyes at V0, in 10% at V1 and in 15% at V2. Colour vision was barely affected. Visual field (VF) was affected (>grade 0) in 87% of eyes at V0 and VF defect grade significantly improved by 0.58 at V1 (p‐value <0.0001) and by 0.55 at V2 (p‐value <0.001). The most common type of VF defect at V0 was a nerve fibre layer defect (56.4%), and the second most common type was an enlarged blind spot (20.5%). There was no correlation between BCVA and VF defect type. Mean grade of papilloedema decreased from 2.2 at V0 to 0.5 at V2. The grade of papilloedema at V2 was not significantly related to the severity of papilloedema at V0 (p‐values 0.65 and 0.48).ConclusionIdiopathic intracranial hypertension (IIH) is associated with long‐term loss of visual function, and relevant treatment strategies need to be improved.
Consistency in land‐cover mapping: Influence of field workers, spatial scale and classification system

Published: February 2018

AbstractQuestionsLand‐cover maps are used for nature management, but can they be trusted? This study addresses three questions: (1) what is the magnitude of between field worker inconsistencies in land‐cover maps and what may cause such inconsistencies; (2) in which ways and to what extent do spatial scale and mapping system influence inconsistencies between maps; and (3) are some biomes mapped more consistently than others, and if so, why?LocationGravfjellet, Øystre Slidre municipality, southern Norway.MethodsTwo different mapping systems, designed for mapping at different spatial scales, were used for parallel mapping by three different field workers, giving a total of six maps for the study area. Spatial consistency of the resulting maps was compared at two hierarchical levels for both systems.ResultsThe average pair‐wise spatial consistency at the highest hierarchical level was 83% for both systems, while the average pair‐wise spatial consistency at the lowest hierarchical level was 60.3% for the coarse system and 43.8% for the detailed system. Inconsistencies between maps were partly caused by the use of different land‐cover units and partly by spatial displacement.ConclusionsField workers made different maps despite using the same mapping systems, materials and methods. The differences were larger at lower hierarchical levels in the mapping systems and increased strongly with system complexity. Consistency among field workers should be estimated as a standard quality indicator in all field‐based mapping programmes.
Fifty years of colic surgery
Authors: Freeman D. E. 
Published: February 2018

SummaryColic surgery is one of few treatments in which a veterinarian can use a skill to save an animal's life from a deadly disease within a short timeframe. Unfortunately, such success is not achieved without considerable risk for surgical failure, which is responsible for most complications in the immediate post‐operative period. The last 50 years have witnessed considerable improvements in colic surgery, although a ranking of the most important ones might not meet with universal agreement. Teamwork plays a critical role in the final outcome, starting and finishing with the referring veterinarian and owner. These individuals are responsible for promptly transferring the horse to a surgical facility and then dealing with aftercare and delayed complications. The surgeon is responsible for the intervening steps, including the decision on the need for surgery, and works with the anaesthesiologist to help a metabolically challenged patient to tolerate surgery and anaesthesia. Although early referral and improved diagnostic procedures can have a positive influence on survival, perceived improvements in surgery and anaesthesia need to be reviewed with some circumspection. Although more rigorous definitions and statistical analyses used in recent studies can invalidate comparisons with older studies, complication rates appear to be on the rise, despite putative improvements in dealing with them. This trend tends to diminish the value of colic surgery through increasing costs, overreliance on post‐operative pharmacological management, growing pessimism, high rates of intraoperative euthanasia, and possibly reduced long‐term survival. Future efforts should address these concerns, mostly through emphasis on prompt referral, good surgical technique and reducing the cost of colic surgery to an affordable level that saves more lives.

ObjectiveTo examine daily patterns of exercise among older husbands and wives, as well as how conjoint exercise was related to daily marital functioning outcomes.BackgroundHealthy lifestyle practices are becoming more common as people prepare to live healthily into their later years. Exercise may provide unique relationship benefits for individuals and couples.MethodThe sample of 191 older couples was drawn from the broader Life and Family Legacies Study, and the present study included data from across 14 days. Multivariate multilevel models were estimated in SAS using the Proc Mixed procedure to examine associations between exercise and daily positive marital events, daily negative marital events, and satisfaction with daily marital interactions.ResultsIndividual exercise on a given day was associated with more positive marital events and higher daily marital satisfaction; patterns in these results were more consistent for wives than for husbands. Conjoint exercise on a given day was also associated with nearly all marital outcomes for both husbands and wives.ConclusionExercise may provide unique relationship benefits for individuals and couples. Results indicated that relationships benefit from both individual and especially conjoint couple exercise.ImplicationsCouples who exercise conjointly may experience more positive marital interactions.
Creating home: Intersections of memory and identity
Authors: Ratnam Charishma 
Published: February 2018

AbstractThe concepts of memory, identity, and place form key debates in geographical literature because they link people to place. Memory incorporates narratives of the past that are articulated in the present day and can inform the way identities are constructed. The intersections of memory and identity can prompt us to think about how we experience and/or have experienced place(s). In this review, I trace discussions that position memory and identity as meta‐concepts that coalesce with the home and home‐building practices. I situate this discussion in and around the home because the home is commonly our most frequented place. It is a place where our person‐place bonds develop through everyday encounters and practices. I explore how memory, identity, and place have been broached in the home by using more‐than‐representational approaches. I have turned to more‐than‐representational theory to flesh out how enactments and encounters with objects and other materialities in the home demonstrate agency and connections to the home, which are indicative of memory and identity in action. Sensory and material encounters provoke remembrances and identifications with home(lands) through objects, people, food, and places that hold particular resonance among migrants.

Scala Civium: Citizenship Templates Post‐Brexit and the European Union's Duty to Protect EU Citizens
Authors: Kostakopoulou Dora 
Published: February 2018

AbstractBrexit opened the way for the ‘restoration’ of British sovereignty and, if an EEA model (or an EEA‐like model) is not chosen following the activation of Article 50 TEU, EU citizens settled in the UK will be requested to apply for either UK nationality or permanent leave to remain. The same applies to UK nationals residing in other Member States who will lose their EU citizenship status. Unexpectedly, 3.9 million EU citizens have been transformed into ‘guests’ or ‘foreigners’ in communities they call ‘their own’. Although naturalization in the state of residence might be seen to furnish a secure and fully recognized status for EU citizens, I argue that it is not an adequate policy option. The conceptual differences between national and EU citizenships are immense. In this article I explore the advantages and disadvantages of possible citizenship templates and propose an ‘EU protected citizen’ status for EU citizens.
Factors associated with delayed referral for infantile hemangioma necessitating propranolol

Published: February 2018

AbstractBackgroundOral propranolol is the gold standard to treat infantile hemangiomas. There is better efficacy and a lower risk of sequelae if therapy is started before the end of the growth phase, but most children are referred too late. Herein, we report the first study to investigate the delay and its associated factors when referring infants with infantile hemangiomas that need propranolol therapy.ObjectivesThe primary objective was to determine the delay in referral (time between age at referral [first phone contact] and the optimal age for referral (fixed at 75 days). The second objective was to determine the impact of weighted factors associated with delayed referral assessed by logistic regression performed on two subgroups (referral ≤75 vs. >75 days).MethodsMonocentric, retrospective, observational study included infants with infantile hemangiomas treated with oral propranolol between August 2014 and May 2017.ResultsEighty‐two children (83% females) were included. Before referral, 81 (99%) children had seen another physician (a paediatrician in 67% of cases). Median age at referral was 99 days [2–478] and 63% phoned after 75 days. Median age at the first visit was 111 days [2–515], and median age when propranolol was started was 128 days [32–541]. After adjustment, in multivariate analyses, location on the lips (OR (CI 95%): 4.21[1.19–14.89]) and superficial hemangioma (OR (CI 95%): 4.19 [1.55–11.34]) emerged as the most significant factors to influence referral before 75 days.ConclusionsThis study adds to our understanding regarding delayed referral and has identified targets for future information campaigns.
