Semantic text-based image retrieval with multi-modality ontology and DBpedia
Authors: M.K. Yanti Idaya Aspura , Mohd Noah Shahrul Azman 
Published: October 2017

PurposeThe purpose of this study is to reduce the semantic distance by proposing a model for integrating indexes of textual and visual features via a multi-modality ontology and the use of DBpedia to improve the comprehensiveness of the ontology to enhance semantic retrieval.Design/methodology/approachA multi-modality ontology-based approach was developed to integrate high-level concepts and low-level features, as well as integrate the ontology base with DBpedia to enrich the knowledge resource. A complete ontology model was also developed to represent the domain of sport news, with image caption keywords and image features. Precision and recall were used as metrics to evaluate the effectiveness of the multi-modality approach, and the outputs were compared with those obtained using a single-modality approach (i.e. textual ontology and visual ontology).FindingsThe results based on ten queries show a superior performance of the multi-modality ontology-based IMR system integrated with DBpedia in retrieving correct images in accordance with user queries. The system achieved 100 per cent precision for six of the queries and greater than 80 per cent precision for the other four queries. The text-based system only achieved 100 per cent precision for one query; all other queries yielded precision rates less than 0.500.Research limitations/implicationsThis study only focused on BBC Sport News collection in the year 2009.Practical implicationsThe paper includes implications for the development of ontology-based retrieval on image collection.Originality valueThis study demonstrates the strength of using a multi-modality ontology integrated with DBpedia for image retrieval to overcome the deficiencies of text-based and ontology-based systems. The result validates semantic text-based with multi-modality ontology and DBpedia as a useful model to reduce the semantic distance.
Using author tri-citation analysis to map knowledge domains in knowledge representations
Authors: Yu Weidong 
Published: October 2017

Purpose
Previous commonly used author co-citation analysis (ACA) methods have limited the ability to deal with accidental co-citation in constructing a raw co-citation matrix. Therefore, the purpose of this paper is to propose a new method, called author tri-citation analysis (ATA), to better map knowledge domains and depict scientific intellectual structures.

Design/methodology/approach
Different from the previous method of using ACA that captures author co-citation relationships, the ATA method seeks tri-citation relationships among authors. Compared with ACA, ATA can ignore some accidental co-citation relationships between authors and can improve the accuracy of mapping knowledge domains.

Findings
Although ATA does not mine more sub-fields than ACA does, the results of the empirical studies show that ATA, the newly proposed method, performs better in knowledge domain maps based on publications in the field of computer science.

Research limitations/implications
The definition of ATA in this article is simple and still insufficiently informative. Many other pieces of information can be involved; for example, all authors’ information, authors’ sequence in the author list, reference published time and similar. These can be enhanced in future studies.

Practical implications
This research will enrich the methods of mapping knowledge domains due to its new perspective.

Social implications
Knowledge domain mapping is important to understand a discipline, and this research provides more potential methods for this, which benefits the performance of the maps.

Originality/value
ATA can provide a methodological awareness for mapping knowledge domains. This value lies in not only a tri-citation perspective, but also author bibliographic tripling and author tri-operation perspectives (“tri-” perspectives).
What drives housing prices, rent and new construction in China
Authors: Staikos Dimitrios , Xue Wenjun 
Published: October 2017

PurposeWith this paper, the authors aim to investigate the drivers behind three of the most important aspects of the Chinese real estate market, housing prices, housing rent and new construction. At the same time, the authors perform a comprehensive empirical test of the popular 4-quadrant model by Wheaton and DiPasquale.Design/methodology/approachIn this paper, the authors utilize panel cointegration estimation methods and data from 35 Chinese metropolitan areas.FindingsThe results indicate that the 4-quadrant model is well suited to explain the determinants of housing prices. However, the same is not true regarding housing rent and new construction suggesting a more complex theoretical framework may be required for a well-rounded explanation of real estate markets.Originality/valueIt is the first time that panel data are used to estimate rent and new construction for China. Also, it is the first time a comprehensive test of the Wheaton and DiPasquale 4-quadrant model is performed using data from China.
Sustainable financing and anti-squandering measures in Rastin banking
Authors: Bidabad Bijan , Sherafati Mahshid 
Published: October 2017

Purpose
This paper aims to define a set of anti-squandering guideposts to improve the sustainability and efficiency of allocating financial resources to investment projects.

Design/methodology/approach
A set of sustainable financing and anti-squandering measures are proposed for a better allocation of the bank’s financial resources. These measures were derived from the doctrine of “ethic economics”, humanitarian principles and Islamic teachings. Rastin banking provides a base to apply these measures.

Findings
A draft of the regulations for sustainable financing and anti-squandering measures was compiled for Rastin banking operations, which is briefly presented in this paper and can be used as a basis for the codification of the respective laws.

Research limitations/implications
Such kinds of regulations are novel and need to be deeply discussed in the first place. After adaptation, adjustment and performing the necessary modifications, the text of the law can be codified.

Practical implications
Banks through granting loans, credits and other financial facilities can affect the investment projects in such a way to prevent the extravagant consumption of financial resources in investment projects and consider the sustainable development guidelines.

Social implications
The proposed guideposts can be detailed and adopted in other countries, especially those that are inefficient in their banking and financial operations.

Originality/value
Wasteful allocation of financial resources leads to the wastage of resources and reduction of productivity and provides benefit neither for the people nor for the society. Hence, the present paper tries to practically solve the problem for financial operations.
Mortgage Securitization System (MSS) (a complementary system of Rastin Banking)
Authors: Bidabad Bijan 
Published: October 2017

Purpose
This paper aims to define a new system to facilitate obtaining reliable collaterals and guarantees for financial activities from tangible assets through a new financial instrument of “guarantee certificates”.

Design/methodology/approach
This system makes it possible to securitize movable/immovable assets into negotiable paper lots, namely, “guarantee certificates”. Each lot of these certificates can be used as a guarantee or collateral for any guarantee-backed activity in banks or other activities.

Findings
The mortgage securitization system (MSS) securitizes tangible assets and provides necessary collaterals and guarantees to be used for different purposes. The operations are carried out through notary offices. This system, as a complementary system of the Rastin Banking system, can also be executed separately.

Research limitations/implications
The system is novel and needs to be more elaborated for further practical development and adjustment. Although this paper deals with only securitization of tangible assets, research can also be extended to securitization of intangible assets, through new institutions and rules.

Practical implications
Many properties and assets can be used as guarantees for observing obligations. The available ways for changing (especially large) properties into small guarantees are not easy and efficient. The MSS was designed to break large assets into many guarantee (certificate) lots and reduce the formalities of mortgaging and its transfer.

Social implications
This system provides reliance and security upon collaterals and conditions for fast claim-clearing and low formalities without time-consuming adjudication processes.

Originality/value
Complementary systems in Rastin Banking have been designed to solve prevailing problems of banking and financial activities. The MSS was designed to provide necessary arrangements for transforming assets into negotiable papers.
Employee revenge against uncivil customers
Authors: Bedi Akanksha , Schat Aaron C.H. 
Published: October 2017

PurposeThis study aims to examine the relations between service employee blame attributions in response to customer incivility and revenge desires and revenge behavior toward customers, and whether employee empathy moderated these relations.Design/methodology/approachThe authors used survey data based on the critical incident method provided by a sample of 431 customer service employees.FindingsThe results suggested that blaming a customer was positively associated with desire for revenge and revenge behaviors against the uncivil customer. In addition, the authors found that blame was less strongly associated with desire for revenge when employees empathized with customers. Finally, the results show that an employee who desired revenge against the uncivil customer and who empathized with the customer was more – not less – likely to engage in revenge.Practical implicationsThe authors found that when employees experience mistreatment from customers, it increases the likelihood that they will blame the offending customer and behave in ways that are contrary to their organization’s interests. The results suggest several points of intervention for organizations to more effectively respond to customer mistreatment.Originality/valueIn this study, the authors make one of the first attempts to investigate the relationships between service employee attributions of blame when they experience customer incivility, desire for revenge and customer-directed revenge behaviors. The authors also examined whether empathy moderates the relations between blame attribution, desires for revenge and revenge behavior.
Explaining customers’ financial service choice with loyalty and cross-buying behaviour
Authors: Estrella-Ramón Antonia 
Published: October 2017

PurposeThis paper aims to examine the impact of the customer’s previous transaction behaviour (represented by loyalty and general cross-buying) on his/her choice of specific services offered by the same financial services provider.Design/methodology/approachThis study uses a set of logistic regression models by incorporating panel data from a large bank. The database consists of 2,187 randomly selected customers, and it includes features related to individual loyalty and cross-buying behaviours, as well as demographic indicators, i.e. individual measures related to each customer and each service.FindingsFrom the results obtained, a large variation in customer choice behaviour with regard to the studied banking services was observed. These results reveal which customer transactional behaviours drive cross-category financial services purchases.Originality/valueIn academic literature, little progress has been made in the study of individual and behavioural factors that affect customer choices by service category, especially within the banking sector. By understanding customer choices, the company will be able to meet customer needs in a more appropriate way, thereby increasing its competitiveness. Hence, the results from this study have both managerial and research implications, improving the strategy formulation of financial services companies.

AbstractBackground and aimsSimilar to substance addictions, reward‐related cognitive motivational processes, such as selective attention and positive memory biases, have been found in disordered gambling. Despite findings that individuals with substance use problems are biased to approach substance‐related cues automatically, no study has yet focused on automatic approach tendencies for motivationally salient gambling cues in problem gamblers. We tested if moderate‐ to high‐risk gamblers show a gambling approach bias and whether this bias was related prospectively to gambling behaviour and problems.DesignCross‐sectional assessment study evaluating the concurrent and longitudinal correlates of gambling approach bias in moderate‐ to high‐risk gamblers compared with non‐problem gamblers.SettingOnline study throughout the Netherlands.ParticipantsTwenty‐six non‐treatment‐seeking moderate‐ to high‐risk gamblers and 26 non‐problem gamblers community‐recruited via the internet.MeasurementsTwo online assessment sessions 6 months apart, including self‐report measures of gambling problems and behaviour (frequency, duration and expenditure) and the gambling approach avoidance task, with stimuli tailored to individual gambling habits.FindingsRelative to non‐problem gamblers, moderate‐ to high‐risk gamblers revealed a stronger approach bias towards gambling‐related stimuli than neutral stimuli (P = 0.03). Gambling approach bias was correlated positively with past‐month gambling expenditure at baseline (P = 0.03) and with monthly frequency of gambling at follow‐up (P = 0.02). In multiple hierarchical regressions, baseline gambling approach bias predicted monthly frequency positively (P = 0.03) and total duration of gambling episodes (P = 0.01) 6 months later, but not gambling problems or expenditure.ConclusionsIn the Netherlands, relative to non‐problem gamblers, moderate‐ to high‐risk gamblers appear to have a stronger tendency to approach rather than to avoid gambling‐related pictures compared with neutral ones. This gambling approach bias is associated concurrently with past‐month gambling expenditure and duration of gambling and has been found to predict persistence in gambling behaviour over time.
A practical guide to the preparation and use of metal ion‐buffered systems for physiological research

Published: October 2017

AbstractRecent recognition that mobile pools of Zn2+ and Cu2+ are involved in the regulation of neuronal, endocrine and other cells has stimulated the development of tools to visualize and quantify the level of free trace metal ions. Most of the methods used to measure or control loosely bound metals require reference media that contain exactly defined free concentrations of the target ions. Despite the central importance of proper metal ion buffering, there is still a lack of international standards and beginners in the field may have difficulties finding a coherent description of how to prepare trace metal ion buffers, especially when experiments are to be performed in multimetal systems. To close this gap, we provide a guide for the design, preparation and use of metal ion‐buffered systems that facilitate immediate application under physiologically relevant ionic conditions. Thermodynamic and kinetic concepts of chemical speciation as well as general protocols and specific examples are outlined for the accurate preparation of single‐ and dual‐metal ion buffers. In addition, experiments have been performed with FluoZin‐3 to illustrate that metal ion‐buffered systems are required for reliable preparation of nanomolar Zn2+ solutions and that dual‐metal ion buffers can be used to calibrate suitable fluorescent Zn2+ sensors in the presence of millimolar Ca2+ concentrations. Together, the information provided should sensitize readers to the many potential pitfalls and uncertainties that exist when working with physiologically relevant concentrations of trace metal ions and enable them to formulate their own metal ion buffers for most in vitro applications.
TRADER TYPE EFFECTS ON THE VOLATILITY‐VOLUME RELATIONSHIP EVIDENCE FROM THE KOSPI 200 INDEX FUTURES MARKET
Authors: Kartsaklas Aris 
Published: October 2017

ABSTRACTWe investigate whether the trading activity generated by investors with different access to information and trading motives has positive or negative impact on index futures volatility. Surprises in non‐member institutional, individual and foreign investors' trading volume are positively associated with volatility in most of the cases. For member institutional investors, unexpected trading volume is positively related to volatility. Long‐run changes in the trading activity also affect volatility differently across trader types. Finally, allowing for time‐to‐maturity effects, surprises in open interest are associated with more volatility towards contract expiration, contrary to the negative effect we find during normal times.
A service review to assess if innovative intensive phosphate dietary education can help reduce phosphate levels to the recommended range in a hemodialysis population
Authors: Duff Eileen A , Chawke Fiona M 
Published: October 2017

AbstractIntroduction: Studies suggest that hemodialysis (HD) patients are less likely to adhere to phosphate dietary restriction than to potassium, sodium, or fluid restriction. It is particularly important that dietary education is provided appropriately, consistently, and reinforced regularly to encourage compliance with diet and phosphate‐binder regimens. Patient awareness of the consequences of a chronically raised phosphate and its treatment is associated with lower serum phosphate levels.Objective: The aim of this study was to assess the impact of a structured educational program on patient knowledge and control of serum phosphate in a maintenance HD population.Methods: Thirty‐six patients with a phosphate level >1.7 mmol/L for the previous 3 months were assessed. A phosphate knowledge questionnaire was devised by the authors and completed by the patient group. This focused on patient knowledge of dietary sources of phosphate and complications of high phosphate levels. The education program was divided into three modules and was based around diet, phosphate additives, and complications of hyperphosphatemia. Visual aids, oral, and written information were provided to each patient throughout the sessions. Seventeen patients completed the education sessions. The knowledge and food frequency questionnaire were repeated at the end of the modules to assess change.Results: Phosphate levels dropped from an average of 2.12–1.73 mmol/L over the education period with a significance level of P = 0.000481 (significant if P < 0.001). This average falls in line with recommended guidelines. Knowledge questionnaire results improved overall.Conclusion: This education program displayed excellent outcomes with an overall reduction in phosphate levels and an improved phosphate knowledge among our sampled HD population. This education program shows that discovering novel ways of education is crucial to enhancing dietetic practice with renal dietitians best placed to deliver patient specific phosphate education.
MicroRNA 499 gene expression in patients on hemodialysis with cardiovascular complications

Published: October 2017

AbstractBackground: MicroRNA (miRNA) 499 is an evolutionarily conserved muscle‐specific miRNA that is encoded by an intron of the myh7 gene and is likely to play a role in myosin gene regulation. It has been shown to be involved in inhibiting apoptosis and myocardial infarction induced by ischemia and anoxia. It is unknown whether levels of miRNAs are affected in patients undergoing hemodialysis.Objective: The aim of this study was to assess circulating levels of miRNA 499 in hemodialysis patients and whether the levels are affected by dialyzer membranes (high flux vs. low flux).Methods: The studied population consisted of 32 end stage renal disease (ESRD) patients (22 males and 10 females) with age ranged from 38% to 75% years on regular hemodialysis (4 hours, 3 times weekly) for at least 1 year duration with cardiovascular events in the last 6 months and 32 healthy controls (20 males and 12 females) with an age range from 54 to 60 years. Patients were involved into a two‐stage sequential study; high‐flux hemodialysis stage (stage I), then low‐flux hemodialysis stage (stage II). Expressed levels of plasma miRNA 499 have been measured by Real Time‐PCR. Lipid profile, serum phosphorus, serum calcium, serum creatinine, and blood urea were measured in all patients.Results: In this study, 2 patients with an open‐heart surgery showed highly elevation in the miRNA 499, while the other patients, showing different degrees of ischemia, had different levels of elevated miRNA 499. Statistically significant higher levels of miRNA 499 in plasma were observed in all the studied patients with cardiovascular diseases compared to the levels of miRNA 499 found in healthy controls (P < 0.0001). MicroRNA 499 was found to be a dialyzable marker. A significant decrease in plasma levels of miRNA 499 was obtained after either high‐flux or low‐flux dialysis compared to plasma levels of miRNA 499 found before dialysis (P < 0.0001). On comparing both types of hemodialysis membranes with respect to miRNA 499 clearance, we found that low‐flux membrane showed better clearance for miRNA 499 than high‐flux membrane with a statistically significant difference between them (P < 0.001).Conclusion: In conclusion, miRNA 499 levels are elevated in patients with ESRD with cardiovascular complications. High‐flux membrane seems to be less efficient in miRNA 499 clearance in cardiac patients on hemodialysis.
