Abstract

Purpose

The purpose of this paper is to introduce an empirical model for house price spillovers between real estate markets. The model is presented by using data from the US-UK and London-New York housing markets over a period of 1975Q1-2016Q1 by employing both static and dynamic methodologies.

Design/methodology/approach

The research analyzes long-run static and dynamic spillover elasticity coefficients by employing three methods, namely, autoregressive distributed lag, the fully modified ordinary least square and dynamic ordinary least squares estimator under a Kalman filter approach. The empirical method also investigates dynamic correlation between the house prices by employing the dynamic control correlation method.

Findings

The paper shows how a dynamic spillover pricing analysis can be applied between real estate markets. On the empirical side, the results show that country-level causality in housing prices is running from the USA to UK, whereas city-level causality is running from London to New York. The model outcomes suggest that real estate portfolios involving US and UK assets require a dynamic risk management approach.

Research limitations/implications

One of the findings is that the dynamic conditional correlation between the US and the UK housing prices is broken during the crisis period. The paper does not discuss the reasons for that break, which requires further empirical tests by applying Markov switching regime shifts. The timing of the causality between the house prices is not empirically tested. It can be examined empirically by applying methods such as wavelets.

Practical implications

The authors observed a unidirectional causality from London to New York house prices, which is opposite to the aggregate country-level causality direction. This supports London’s specific power in the real estate markets. London has a leading role in the global urban economies residential housing markets and the behavior of its housing prices has a statistically significant causality impact on the house prices of New York City.

Social implications

The house price co-integration observed in this research at both country and city levels should be interpreted as a continuity of real estate and financial integration in practice.

Originality/value

The paper is the first research which applies a dynamic spillover analysis to examine the causality between housing prices in real estate markets. It also provides a long-term empirical evidence for a dynamic causal relationship for the global housing markets.

Abstract

Purpose

The purpose of this paper is to understand young children’s knowledge of visual literacy elements as well as their ability to comprehend newly introduced visual literacy concepts. The study also examined existing support for visual literacy programs from parents and educators.

Design/methodology/approach

The study explored the knowledge of basic visual literacy elements of young children enrolled in two private schools in the New York City metropolitan area. The authors interviewed 17 children, aged four to six years old, about fine art paintings using a semi-structured interview format. Children’s responses were qualitatively analyzed to determine their initial level of visual literacy and their ability to learn and retain the concepts of visual literacy after receiving basic instruction. The children’s educators and parents completed online questionnaires that were quantitatively analyzed to determine their level of support for visual literacy programs.

Findings

The findings show that young children exhibited extensive knowledge of simple visual literacy elements (color, shape, line), and limited understanding of more abstract elements (perspective and salience). Children’s knowledge of visual elements improved after instruction. Parents and educators expressed support for incorporating visual literacy instruction in early childhood education.

Research limitations/implications

The study relied on a sample of children and adults drawn from two private schools. The sample’s demographics might have affected study findings. More studies are needed using a larger and more diverse sample.

Practical implications

The study suggests that young children are ready to receive instruction on visual literacy elements using art images. Children reacted positively to the images and were engaged in the discussions about them, supporting the use of fine art paintings as an instrument to introduce visual literacy concepts to young children. Survey of children’s parents and teachers indicated strong interest in, and support for such programs.

Social implications

With the increase of visual information production and consumption, it is important to introduce visual literacy early in life. The study advances research in methods for developing visual literacy instruction for young children.

Originality/value

There are no previously reported studies that have examined pre-kindergarten children’s knowledge of basic visual literacy elements and reactions to visual literacy instruction.

Abstract

Since 2004, Turkish cinema has been witnessing an emergence of horror genre, now flooded with stories of possession by malevolent jinn, as transgressive, volatile figures of abjection. These female-centred narratives rely both on Islamic cosmology and myths and folktales of pre-Islamic Anatolian oral culture. The chapter will first explore the reasons horror has been neglected in the century-long history of cinema in Turkey and move on to highlight the socio-economic, cultural, and political contexts that were catalysts for the horror genre’s emergence. Then, the chapter will discuss the codes and conventions of the genre and explore the unique place of Alper Mestçi’s 2007 film Haunted (Musallat), among its contemporaries in terms of the ways in which the film challenges these established codes and conventions. In analysing Haunted, the chapter will use the theoretical framework of Barbara Creed, Carol J. Clover and Julia Kristeva to discuss the monstrous-feminine and masculinity as abjection.

Abstract

Purpose

Existing treatments for alcohol and substance dependence are of limited efficacy and acceptability to users. Since such dependence is associated with high co‐morbidity and mortality rates, alternative treatments should be urgently evaluated. Ibogaine, a hallucinogenic alkaloid, derived from Tabernanthe Iboga, a plant unique to the rainforests of West Africa, is already associated with a large underground treatment scene. This paper aims to explore this issue.

Design/methodology/approach

The paper draws on the comparative ethnography of magicoreligious Iboga use in West Africa alongside contemporary accounts of ibogaine addiction treatment, and contextualizes these within the neurobiology and anthropology of addiction and treatment provision.

Findings

While the exotic otherness of ibogaine no doubt contributes to interest and hope, the impact of the medicine, not just on craving and withdrawal, but on the perceived acquisition of psycho‐spiritual insight, may validate such anticipation. Both West African and Western Ibogaine use are explored in the context of oppression, resistance and a re‐asserted morality. Successful ibogaine treatments appear to respect but transform existing subcultural meanings and identities, while promoting realism and psychosocial integration.

Practical implications

Existing treatment programmes might learn from the inherent critique of conventional treatment enacted in ibogaine treatment scenes.

Social implications

Lack of mainstream investment may partly reflect the cultural positioning of drug‐users (and of this drug‐class) yet the scale of underground ibogaine use demands urgent funding for research to optimise safety and further understanding/development.

Originality/value

An understanding of how addicts seeking ibogaine are culturally positioned, and position themselves, illuminates the specific attraction of ibogaine treatment for this group, and has important implications for practice, drug policy and treatment development.

Abstract

In the 1967 film, The Graduate, Mr. Robinson gave Dust in Hoffman's character, Benjamin, the scene‐stealing career suggestion, “plastics!” Although Benjamin appeared indifferent to the oracle‐like advice, thousands of other graduates have since helped to make plastics, or polymers, a popular career choice. Today, the U.S. polymer‐based industries (plastics, rubber, fibers, paints, films, membranes, coatings, and adhesives) employ more than a million workers and need 10,000 new graduates yearly to support their growth. Yet, despite the emphasis industry and government place on formal training in polymer science and engineering (hereafter called PSE), academia has given the rapidly developing field a cool reception. Science writer Joseph Alper notes:

Abstract

The use of foresight as a tool in policy and strategic decision making increased especially in the last decade of the twentieth century in order to enhance competitiveness and innovation of nations, regions, corporations and even individuals. Coupled with this development a lot of different definitions which partly include part of the others emerged in the literature. However, it was observed that none of these definitions were capable enough to represent an integrated and holistic view about the impact of foresight on the management of the future. In this article, the integrated foresight management model is introduced which is based on the integrated management model but enriched by a knowledge‐people‐system‐organisation framework. The current list of definitions was tabulated in this new model and the vacancies in the model were filled out. This integrated foresight management model can help practitioners in designing national, regional or corporate programs in developing necessary organisational structures, deliverables and behaviours on policy, strategy and operational levels of management.

Abstract

Purpose

Beside the development of technology and accessibility, ease of use, ability to reach various products and compare many products at the same time make online shopping even more popular. Despite the great advantages provided by online shopping for either consumers or retailers, there are certain issues that must be solved to improve online shopping advantages. Finding right size is one of the biggest barriers against apparel online retailing. Since the use of apparels is directly related with fitting, choosing right size is becoming more critical for retailers and consumers. The purpose of this paper is to contribute to the solution of the problem.

Design/methodology/approach

For the study, the specific size measurements of male shirts (collar, shoulder, chest, waist, arm length in cm) from four different sizes (small, medium, large, x-large) and from eight different brands were collected and stored in a database. Totally, weight, height and body measurements (collar, shoulder, chest, waist and arm length in cm) of 80 male candidates, between the ages of 18 and 35, were measured individually. These data were then used for experiments.

Findings

Any product with known measurements can be compared with users’ body measurement based on fuzzy logic rule and the best-fitted size can be selected for users. Similarly, using the proposed web design, users are able to see desired products on users with similar body type.

Originality/value

In this study, a new mathematical method based on fuzzy relations for apparel size finder is proposed. Beside, this method can group users based on body measurements in order to find people with similar size.

Abstract

Purpose

Despite being a low-tech industry, woodwork manufacturing industry that includes furniture and cabinet making, witnessed technological leaps in production technologies due to technical developments in computer numerical control (CNC) machining processes. The managers of this industry have attached high importance to the selection of efficient machines as their decisions directly affect the quality and performance of products produced by the firms. Improper selection process can result in a significant decrease in productivity and flexibility. Therefore, a systematic decision-making procedure is needed to prevent inaccurate investments on machines. The purpose of this paper is to purpose a hesitant fuzzy analytic hierarchy process (HFAHP) based multi-criteria decision making (MCDM) system for CNC router selection in small- and medium-sized enterprises (SMEs) in woodwork manufacturing.

Design/methodology/approach

The study proposes a hierarchical model consisting of 4 main criteria and 11sub-criteria for woodwork manufacturing. Technical, personnel, economic and vendor aspects constitute the main criteria. Because of the hierarchical structure of the model, HFAHP is utilized to define the importance weights of the criteria, and to select the most appropriate CNC alternative for a manufacturing company under focus. In a selection procedure, the judgments of decision makers may have vagueness to specify the importance of criteria affecting the decision process. In the literature, the fuzzy set theory has been utilized to deal with such uncertainties. However, when the ideas of the managers have high potential to fall into contradiction in pairwise comparisons, a novel approach is needed to overcome the obstacles. HFAHP allows the membership degree having a set of possible values. It is specifically useful in compromised decisions where experts cannot agree on a single value and prefer to come up with an interval of linguistic variables.

Findings

It is revealed that for SMEs in woodwork manufacturing, the most important criterion in selecting the CNC routers is the technical aspects. It may seem counter intuitive that they do not refrain finding the technical criteria superior to the economic aspects, even though they have limited budgets compared to large-scale firms. This demonstrates that in current competitive environment, SMEs understand the need for high-quality production strategy. The weights of the remaining two criteria (personnel and vendor aspects) are relatively low because they expect that they can easily overcome the problem of adapting the workers by training, and all vendors have quality standard qualifications so they can offer a satisfactory service and supplementary systems.

Practical implications

The ready-to-use model proposed is specialized for SMEs in woodwork manufacturing. However, to make it an easily adaptable model for every company in the woodwork industry regardless of its size, the calculation process of the priority weights is illustrated in detail with a numerical example. Any company can follow the process using their own preferences to end up with a specific model that will perfectly reflect their own specific priorities. For demonstrating the application of the model, a case study is conducted in a woodwork manufacturing SME to select the best CNC router among three alternatives.

Originality/value

The originality and value of the paper is twofold. First, to the best of our knowledge, this is the first study that proposes a woodworking-specific CNC router selection for SMEs. Second, to handle the high uncertainty in the judgements, and to facilitate consensus among the experts during face to face meetings to develop compromised matrices, a very recently developed method, HFAHP is used.

Abstract

Ibogaine therapy offers a viable alternative to mainstream treatment for opiate addiction. The combination of the addiction‐arresting and fast‐acting properties of ibogaine, with the slow and thoughtful conversation of psychoanalytical psychotherapy is a novel approach to what still remains a difficult condition to overcome.Safer than methadone, ibogaine use is steadily increasing world‐wide, and is becoming a more accepted treatment for opiate addiction. This year it has become a prescription medication in New Zealand. Howard Lotsof, who discovered the anti‐addictive properties of ibogaine 47 years ago, and who died in January 2010, devoted his life to improving access to ibogaine treatment, and instigated the first ibogaine providers' conference in Mexico in 2009.This paper explores the use of ibogaine and psychoanalytic psychotherapy in the clinic for the treatment of opiate dependency, the relationships between the two approaches, and how they differ from other treatment modalities.

Abstract

Purpose

Considering the different motivation for the creation of each of these cryptocurrencies, the purpose of this paper is to examine whether there is a dominant external factor in the cryptocurrency world. Using a novel two-step time and frequency independent methodology, the authors examine a large scope of cryptocurrencies and external factors within the same period, and analytical framework.

Design/methodology/approach

The examined cryptocurrencies are Bitcoin, Ethereum, Ripple, Litecoin, Monero and Dash. In total, 18 external factors from 5 factor families are selected based on the mining motivation of these cryptocurrencies. The study first examines discrete wavelet transform-based (WTB) correlations, reduce the dimension and focuson relevant pairs. Selected pairs are further examined by wavelet coherence to capture the intermittent nature of the relationships allowing the most needed “Flexibility of frequency and time domains”.

Findings

Each coin appears to operate as a unique character with the exception of Bitcoin and Litecoin. There is no prominent external driver. The cryptocurrency market is not a clear substitute for a specific factor or market. Two-step WTB filtered wavelet coherence analysis help us to analyze a large number of factor without the loss of focus. The co-movements within the cryptocurrencies spillover from Ethereum to altcoins and later to Bitcoin.

Originality/value

The study presents one of the first examples of two-step WTB filtered wavelet coherence analysis. The methodology suggests an approach for simultaneous examination of large number of variables. The scope of the study provides a rather holistic view of the co-movements of external factors and major cryptocurrencies.
