Multicriteria analysis and genetic algorithms for mass appraisals in the Italian property market
Authors: Morano Pierluigi , Tajani Francesco , Locurcio Marco 
Published: January 2018

PurposeThis paper aims to test and compare two innovative methodologies (utility additive and evolutionary polynomial regression) for mass appraisal of residential properties. The aim is to deepen their characteristics, by exploring the potentialities and the operating limits.Design/methodology/approachWith reference to the same case studies, concerning samples of residential properties recently sold in three Italian cities, the two procedures are tested and the results are compared. The first method is the utility additive, which interprets the process of the property price formation as a multi-criteria selection of multi-objective typology, where the selection criteria are the property characteristics that are decisive in the real estate market; the second method is a hybrid data-driven technique, called evolutionary polynomial regression, that uses multi-objective genetic algorithms to search those models expressions that simultaneously maximize accuracy of data and parsimony of mathematical functions.FindingsThe outputs obtained from the experimentation highlight the potentialities and the limits of the two methodologies, as well as the possibility of jointly applying them to interpret and predict the real estate phenomena in a more realistic representation.Originality valueIn all countries, mass appraisal techniques have become strategic for the definition of management and enhancement policies of public and private property assets, in the case of investments of technical and economic refunctionalization (energy, environment, etc.), and for the alienation of buildings no longer suitable for public needs (military barracks, hospitals, areas in disuse, etc.). In this context, the use of mass appraisal techniques for residential properties assumes a leading role for sector operators (buyers, sellers, institutions, insurance companies, banks, real estate funds, etc.). Therefore, the results of the applications outline the potentialities of the two methodologies implemented and the opportunity of further insights of the topics that have been dealt with in this research.
Herding behavior in Islamic GCC stock market: a daily analysis
Authors: Chaffai Mustapha , Medhioub Imed 
Published: January 2018

Purpose
This paper aims to examine the presence of herd behaviour in the Islamic Gulf Cooperation Council (GCC) stock markets following the methodology given by Chiang and Zheng (2010). Generalized auto regressive conditional heteroskedasticity (GARCH)-type models and quantile regression analysis are used and applied to daily data ranging from 3 January 2010 to 28 July 2016. Results show evidence of herd behaviour in the GCC stock markets. When the data are divided into down and up market periods, herd information is found to be statistically significant and negative during upward market periods only. These results are similar to those reported in some emerging markets such as China, Japan and Hong Kong, where stock returns perform more similarly during down market periods and differently during rising markets.

Design/methodology/approach
The authors present a brief literature on herd behaviour. Second, the authors provide some specificity of the GCC Islamic stock market, followed by the presentation of the methodology and the data, results and their interpretation.

Findings
The authors take into account the difference existing in market conditions and find evidence of herding behaviour during rising markets only for GCC markets. This result was confirmed after using the quantile regression method, as evidence of herding was observed only in highly extreme periods. Stock returns perform more similarly when market is down in Islamic GCC stock market.

Research limitations/implications
The research limitation consists in the fact that this work can be extended to compare the GCC stock markets with other markets in Asia such as Malaysia and Indonesia.

Practical implications
The principal implication consists in the fact that herding behaviour is limited in the GCC markets and Islamic finance can have an important contribution to moderate the behaviour in the financial markets.

Social implications
The work focusses on the role of ethics in the financial markets and their ability to reduce the impact of behavioural biases.

Originality/value
The paper studies the behaviour of investors in the Islamic financial markets and gives an idea about the importance of the behaviour in this particular market regarding its characteristics.
Identifying landmark publications in the long run using field-normalized citation data
Authors: Bornmann Lutz , Ye Adam , Ye Fred 
Published: January 2018

Purpose
The purpose of this paper is to propose an approach for identifying landmark papers in the long run. These publications reach a very high level of citation impact and are able to remain on this level across many citing years. In recent years, several studies have been published which deal with the citation history of publications and try to identify landmark publications.

Design/methodology/approach
In contrast to other studies published hitherto, this study is based on a broad data set with papers published between 1980 and 1990 for identifying the landmark papers. The authors analyzed the citation histories of about five million papers across 25 years.

Findings
The results of this study reveal that 1,013 papers (less than 0.02 percent) are “outstandingly cited” in the long run. The cluster analyses of the papers show that they received the high impact level very soon after publication and remained on this level over decades. Only a slight impact decline is visible over the years.

Originality/value
For practical reasons, approaches for identifying landmark papers should be as simple as possible. The approach proposed in this study is based on standard methods in bibliometrics.
Apps on laps: digital storytimes in public libraries in Aotearoa New Zealand
Authors: Goulding Anne , Shuker Mary Jane , Dickie John 
Published: January 2018

Purpose
The purpose of this paper is to report on a small, exploratory research project focusing on librarian and parent/caregiver opinions of, and reactions to, the use of digital media and technology in public library storytimes for preschool children in Aotearoa New Zealand.

Design/methodology/approach
Telephone interviews with librarians and an online survey of parent/caregivers were undertaken.

Findings
The research found a mixed response to digital storytimes. Those who had not attended or presented digital storytime sessions were largely opposed to the practice, while those who had participated in a storytime using digital media generally held more positive views. Key concerns were focused on the amount of screentime young children should have and a lack of human interaction. Supporters appreciated the introduction of some basic digital literacy skills and the variety that technology could bring to storytime sessions.

Research limitations/implications
Both samples were small and self-selecting. The use of an online survey meant a bias in the sample toward those with access to appropriate information communication technology as well as a self-selection bias.

Practical implications
The paper suggests some developments in practice and approach if librarians are going to play the role of media mentors in their communities.

Originality/value
This is the first study focusing on the development of digital storytimes in Aotearoa New Zealand and adds to knowledge and understanding of key stakeholder views of the inclusion of digital media and technology in public library programming for young children.
The UK Network of Age-friendly Communities: a general review
Authors: Rémillard-Boilard Samuèle 
Published: January 2018

Purpose
The purpose of this paper is to present a detailed account of the work and contribution of the UK Network of Age-friendly Communities, a platform established to support the development of age-friendly communities across the UK.

Design/methodology/approach
This paper draws on a review of both external and internal working documents, communications with network representatives, and an in-depth interview conducted with the current manager of the UK Network of Age-friendly Communities.

Findings
Since its formation, the UK Network of Age-friendly Communities has provided cities with an important platform for knowledge exchange and peer support, and helped build commitment to the age-friendly agenda at the local, national and international level. Through the presentation of various examples, the article illustrates that network members have not only helped drive this agenda forward by developing a collective voice, but also by developing a wide range of initiatives at the local level.

Originality/value
Despite an increased interest in documenting age-friendly experiences around the world, the experience of national programmes remains under-explored in the age-friendly literature to date. To the knowledge, this paper is one of the first to describe the work and contribution of the UK Network of Age-friendly Communities.

Abstract

Anthropogenic practices that facilitate species introductions must be identified and modified to improve management and control the spread of non‐native taxa in many environments. Maintenance practices that remove dense epifaunal invertebrates attached to offshore structures create a disturbance that may facilitate the establishment of non‐native species.

We evaluated the effect of disturbance on the abundance (percent cover) of a non‐native bryozoan, Watersipora subatra, on an offshore oil platform in the Santa Barbara Channel, USA by removing the existing epifaunal community in experimental plots and comparing Watersipora cover in these plots to that in undisturbed control plots over a 15‐month period. We explored the importance of larval supply and the epifaunal community in driving observed patterns, using measurements of Watersipora larval availability and colony recruitment and growth in the disturbed and control plots. We also examined the effect of disturbance on Watersipora establishment at the larger, platform‐scale over c. 18 months with comparative surveys of cleaned and uncleaned portions of another oil platform.

Both the experimental disturbance and the larger platform cleaning facilitated Watersipora establishment, with cover increasing from c. 5% to 20–60% at shallower (≤12 m) depths within 15 to 18 months following disturbance.

Initial Watersipora recruitment to the disturbed plots occurred during a period of elevated larval availability, as indicated by recruitment onto settlement plates. However, 1 year after the experimental disturbance, sessile invertebrates occupied all available settlement space, and there was little recruitment of Watersipora into disturbed plots despite the availability of larvae.

Synthesis and applications. Maintenance operations for offshore structures can include the manual removal of subtidal epibenthic invertebrates attached to the structure. Our study at offshore oil platforms found that this anthropogenic disturbance enhanced the establishment of the non‐native invertebrate Watersipora subatra. The timing of disturbance relative to Watersipora's reproductive season was an important driver of this pattern. Scheduling maintenance practices to occur soon after the reproductive period of Watersipora could allow adequate time for native species to recruit and occupy the available bare space, thereby reducing the potential for establishment of this non‐native species.
Do terrorist attacks affect ethnic discrimination in the labour market? Evidence from two randomized field experiments

Published: January 2018

AbstractTerrorist attacks are known to influence public opinion. But do they also change behaviour? We address this question by comparing the results of two identical randomized field experiments on ethnic discrimination in hiring that we conducted in Oslo. The first experiment was conducted before the 2011 terrorist attacks in Norway; the second experiment was conducted after the attacks. In both experiments, applicants with a typical Pakistani name were significantly less likely to get a job interview compared to those with a typical Norwegian name. But the ethnic gap in call‐back rates were very similar in the two experiments. Thus, Pakistanis in Norway still experienced the same level of discrimination, despite claims that Norwegians have become more positive about migrants after the far‐right, anti‐migrant terrorist attacks of 2011.
Development and application of a new multiplex real‐time PCR assay for simultaneous identification of Brucella melitensis, Cronobacter sakazakii and Listeria monocytogenes in raw milk and cheese
Authors: Tutar Esen , Akıncı Kübra Sueda , Akyol İsmaİl 
Published: January 2018

Brucella melitensis, Cronobacter sakazakii and Listeria monocytogenes are important foodborne pathogens in milk and milk products, which are responsible for a variety of diseases that pose serious hazards to public health and food safety. The objective of this study was to develop a novel multiplex RTi‐PCR for the detection of B. melitensis, C. sakazakii and L. monocytogenes and to characterise the potential risk of these pathogens in raw milk and cheese. The raw milk (n = 25) and cheese samples (n = 20) were analysed by multiplex RTi‐PCR assay and detected for quantification of the three pathogens. In this study, B. melitensis, C. sakazakii and L. monocytogenes were simultaneously identified using BMEII0466, mms operon and hly as target genes, respectively. The multiplex RTi‐PCR assay that was developed showed good sensitivity and selectivity for the pathogenic microorganisms (r2 = 0.986–0.997). Multiplex RTi‐PCR results showed that most of the samples were contaminated with the pathogens screened.

ObjectiveTo examine factors associated with 0‐ to 7‐day admission after outpatient surgery in high‐volume specialties: general surgery, orthopedics, urology, ear/nose/throat, and podiatry.Study DesignWe calculated rates and assessed diagnosis codes for 0‐ to 7‐day admission after outpatient surgery for Centers for Medicare and Medicaid Services (CMS) and Veterans Health Administration (VA) dually enrolled patients age 65 and older. We also estimated separate multilevel logistic regression models to compare patient, procedure, and facility characteristics associated with postoperative admission.Data Collection2011–2013 surgical encounter data from the VA Corporate Data Warehouse; geographic data from the Area Health Resources File; CMS enrollment and hospital admission data.Principal FindingsAmong 63,585 outpatient surgeries in 124 facilities, 0‐ to 7‐day admission rates ranged from 5 percent (podiatry) to 28 percent (urology); nearly 66 percent of the admissions occurred on the day of surgery. Only 97 admissions were detected in the CMS data (1 percent). Surgical complications were diagnosed in 4 percent of admissions. Procedure complexity, measured by relative value units or anesthesia risk score, was associated with admission across all specialties.ConclusionAs many as 20 percent of VA outpatient surgeries result in an admission. Complex procedures are more likely to be followed by admission, but more evidence is required to determine how many of these reflect potential safety or quality problems.
Performance Effects of Setting a High Reference Point for Peer‐Performance Comparison
Authors: EYRING HENRY , NARAYANAN V. G. 
Published: January 2018

ABSTRACTWe conduct a field experiment, based on a registered report accepted by the Journal of Accounting Research, to test performance effects of setting a high reference point for peer‐performance comparison. Relative to providing the median as a reference point for online students to compare themselves to, providing the top quartile: damps performance for those below the median, boosts performance for those between the median and top quartile, and, in the case of outcome but not process comparison, boosts performance for those above the top quartile. We do not find that either reference point yields a greater average performance effect. However, providing the more effective reference point in each partition of initial performance yields a 40% greater performance effect than providing either reference point uniformly. Students access the online courses intermittently over the span of a year. Our effects derive from small portions of our treatment groups—5% in the case of process comparison and 26% in the case of outcome comparison—who accessed treatment and who were, on average, more active leading up to and during our intervention.

AbstractMethamphetamine (METH) increases metabolic neuronal activity in the mesolimbic dopamine (DA) system and mediates the reinforcing effect. To explore the underlying mechanism of acupuncture intervention in reducing METH‐induced behaviors, we investigated the effect of acupuncture on locomotor activity, ultrasonic vocalizations, extracellular DA release in the nucleus accumbens (NAcs) using fast‐scan cyclic voltammetry and alterations of brain temperature (an indicator of local brain metabolic activity) produced by METH administration. When acupuncture was applied to HT7, but not TE4, both locomotor activity and 50‐kHz ultrasonic vocalizations were suppressed in METH‐treated rats. Acupuncture at HT7 attenuated the enhancement of electrically stimulated DA release in the NAc of METH‐treated rats. Systemic injection of METH produced a sustained increase in NAc temperature, which was reversed by the DA D1 receptor antagonist SCH 23390 or acupuncture at HT7. Acupuncture inhibition of METH‐induced NAc temperature was prevented by pre‐treatment with a group II metabotropic glutamate receptors (mGluR2/3) antagonist EGLU into the NAc or mimicked by injection of an mGluR2/3 agonist DCG‐IV into the NAc. These results suggest that acupuncture reduces extracellular DA release and metabolic neuronal activity in the NAc through activation of mGluR2/3 and suppresses METH‐induced affective states and locomotor behavior.

BackgroundAdjuvant therapy for breast cancer is routinely discussed and recommended in multi‐disciplinary meetings (MDMs). Current literature explores how treatments received by patients differ from national guidelines; however, it does not explore whether treatment is concordant with MDMs. This study provides an Australian perspective on the uptake of MDM recommendations and reasons for non‐concordance.MethodsA retrospective cohort study of patients with breast cancer presented at The Royal Melbourne Hospital MDM in 2010 and 2014 to investigate the concordance between MDM recommendations and treatment received.ResultsThe study group comprised 441 patients (161 from 2010 and 280 from 2014). A total of 375 patients were included in the analyses. Overall, 82% of patients had perfect concordance between recommended and received treatment for all modes of adjuvant therapy. Concordance to endocrine therapy was higher for invasive cancers than ductal carcinoma in situ (97% versus 81%, P < 0.0001). Concordance to radiotherapy was high and did not differ according to type of cancer or surgery (ranging from 88 to 91%). Concordance to chemotherapy recommendations was high overall (92%) and did not vary with nodal status. Women aged over 65 years were least likely to be recommended for adjuvant therapy but most likely to concordant with the recommendation.ConclusionsUptake of MDM‐recommended treatments is high. There is a minority of patients in whom MDM recommendations are not followed, highlighting that there are extra steps between recommendations at an MDM and decisions with patients. More attention to this issue is appropriate, and the reasons for non‐concordance warrant further study.
The modality effect in a mobile learning environment: Learning from spoken text and real objects

Published: January 2018

AbstractThe finding that under split‐attention conditions students learn more from a picture and spoken text than from a picture and written text (ie, the modality effect) has consistently been found in many types of computer‐assisted multimedia learning environments. Using 58 fifth‐grade and sixth‐grade elementary school children as participants, we investigated whether the modality effect can also be found in a mobile learning environment (MLE) on plants' leaf morphology, in which students had to learn by integrating information from text and real plants in the physical environment. A single factor experimental design was used to examine the hypothesis that students in a mixed‐mode condition with real plants and spoken text (STP condition) would pay more attention to the real plants, and achieve higher performance on retention, comprehension, and transfer tests than the single‐mode condition with real plants and written text (WTP condition). Whereas we found that participants in the STP condition paid more attention to observing the plants, and achieved a higher score on the transfer test than participants in the WTP condition, no differences were found between the conditions for retention and comprehension test performance.
Haematology patients and the risk of transfusion transmitted infection
Authors: Ainley Louise I. , Hewitt Patricia E 
Published: January 2018

SummaryA 2014 study by NHS Blood and Transplant indicated that over one quarter of red cells were transfused to patients with haematological conditions. For platelet components, the figure is higher. Certain diagnostic groups, such as haemoglobinopathies, myelodysplastic syndromes and some haemato‐oncology patients, receive multiple transfusion episodes, either over long periods, or more intensively over shorter periods. Haematology patients account for the majority of the multi‐transfused population. The risk of transfusion‐transmitted infection (TTI) increases with number of donor exposures, and the consequences of TTI are often more significant in immunosuppressed individuals. Historically, use of pooled plasma products in patients with clotting disorders resulted in widespread transmission of hepatitis B virus, hepatitis C virus and human immunodeficiency virus before effective screening and viral inactivation methods were introduced.
