Abstract

The growing importance of Krakow as the tourist destination in Eastern Europe has inspired changes in its hospitality industry as early as in the mid-nineteenth century. This chapter addresses the following questions – how has the hospitality industry developed during this period? Where did it concentrate? How did the hospitality offer expanded, and was the nature of the competition between owners? Due to the limited availability of historical statistical information on the service industry, the data for this study was derived from guide books, diaries, calendars, and newspapers (“Chronicle of Cracow”) throughout 1848–1939. The authors have examined about 30,500 volumes from which a selection of relevant information and press advertisements was made. Through the examination of historical press announcements for more than 90 years, the authors were able to reproduce the direct location of the hospitality industry objects, their changes of location, the identity of owners, the profile of provided services, and the economic and spatial transformations of the hospitality industry in Krakow.

Abstract

Purpose

The purpose of this paper is to continue studies previously reported with the primary focus of optimizing an inductor design. The potential benefits of hyperthermia for cancer therapy, particularly metastatic cancers of the prostate, may be realized by the use of targeted magnetic nanoparticles that are heated by alternating magnetic fields (AMFs).

Design/methodology/approach

To further explore the potential of this technology, a high‐throughput cell culture treatment system is needed. The AMF requirements for this research present challenges to the design and manufacture of an induction system because a high flux density field at high frequency must be created in a relatively large volume. Additional challenges are presented by the requirement that the inductor must maintain an operating temperature between 35 and 39°C with continuous duty operation for 1 h or longer. Results of simulation and design of two devices for culture samples and for in vitro tests of multiple samples in uniform field are described.

Findings

The inductor design chosen provides a uniform distribution of relatively high magnetic field strength while providing an optimal reduction in the voltage and power requirement. Through development of design and selection of magnetic concentrator, the exposure of the cell cultures to the heat generated by the inductor is minimized.

Originality/value

This method of generating uniform high AC magnetic fields in a large volume is beneficial for the study of hyperthermia in cells for a high throughput, necessary for cancer treatment research.

Abstract

Purpose

The purpose of this study is to obtain an effective implant with porous structures on its surface, named porous-surfaced implant, which helps to improve the overall stability of the implant and promote the combination of implant and alveolar bone.

Design/methodology/approach

Porous-surfaced implants with a porosity of 16%, 21%and 32% were designed and the effect of porosity on the strength of the implant was analyzed by ABAQUS software. Porous-surfaced implants with different porosity were printed by selective laser melting and the surface morphology was observed. Animal experiments of implants with porous structures and coating were carried out in healthy beagle dogs. The experimental group was treated with hydroxyapatite coating and the control group was not treated. Bone volume (BV) and total volume (TV) of the implant surface of the experimental group and control group were calculated by Skyscan CTvol software.

Findings

With the increase of porosity of porous-surfaced implants, the neck stress of the porous-surfaced implants increased and their strength decreased. In addition, in animal vivo experiments, the ratio value of BV to TV of the porous-surfaced implants was between 55.38% and 79.86%, which was the largest when the porosity of porous-surfaced implants was 16%. The internal and surrounding bone formation content of porous-surfaced implants with hydroxyapatite coating was higher than porous-surfaced implants without coating.

Originality/value

The results of this study show that the pores on the surface of implants can be filled with the new bone and porous-surfaced implants with 16% porosity provide better space for the growth of new bone. The porous structures with hydroxyapatite coating are beneficial to the growth of new bone around implants. The results of this study are helpful to improve the overall stability of implants and to promote the combination of implant and alveolar bone.

Abstract

Purpose

The purpose of the paper is to attempt to answer the question of how tourism influences the behaviours connected with natural environment.

Design/methodology/approach

The research is based on the example of the attitude towards water usage among indigenous inhabitants of the Douz, Tozeur and Nefta oases in southern Tunisia. The research was conducted on the basis of the methodology of cultural anthropology, such as indirect and direct observation, verified in the time period between 1983 and 2006, partially categorized questionnaire interviews with natives of Douz, Tozeur and Nefta oases (43 people altogether). A supplement to the questionnaire interviews with natives was the research conducted in a group of hotel managers and tourists. As far as the information on water economy is concerned the author's work is grounded on research conducted simultaneously in the same area by another team as well as on a research conducted in similar environmental conditions.

Findings

The development of the tourism sector in the south of Tunisia started simultaneously with investments in artesian wells and pipelines transporting water to irrigate the oases. Therefore, it is difficult to estimate explicitly to what extent the behaviours concerning water economy were influenced by the investments and to what extent by tourism. Tourism has, however, undoubtedly the function of a “starting factor” which initiated a change in the traditional attitude towards water. As a result, the behaviours of indigenous inhabitants of the dry areas are subject to violent transformation – the highest water usage (often water waste) is observable in the agricultural sector, not in the tourism sector. It is worth emphasizing that the fatal consequences are often provoked not by the tourists' behaviours, but by the behaviour of the hotel staff – frequent filling of swimming pools, excessive watering of hotel gardens – which is being observed by indigenous inhabitants.

Practical implications

The lack restrictions concerning water consumption may undoubtedly lead to “self‐destruction of tourism”. Tunisian Government should definitely intervene in these matters (e.g. through the introduction of water usage restrictions for hoteliers).

Originality/value

Showing the interconnections between the development of the tourism sector specializing in mass tourism services and increased water consumption in the agricultural sector in dry areas.

Abstract

Purpose

This study aims to propose a fuzzy linear regression (FLR) model to deal with the vagueness or fuzziness of the underlying relationship between silk cocoon and yarn quality.

Design/methodology/approach

Shell ratio percentage, defective cocoon percentage and cocoon volume are considered as significant independent variables to predict the quality of silk cocoons. Input and output parameters of the FLR model are considered as non-fuzzy, but the underlying relationship between the variables is assumed to be fuzzy.

Findings

The fuzzy regression model shows its superiority against conventional multiple linear regression model for estimation of silk cocoon characteristics. It is inferred that the fuzziness in underlying relationship between the parameters can be handled efficiently by FLR model.

Originality/value

A rigorous experimental work has been carried out on 40 lots of mulberry silk cocoons to generate real-world data set to characterize silk cocoons’ quality in a fuzzy environment.

Abstract

Purpose

Autism spectrum disorder (ASD) has been studied as a neurodevelopmental disorder since Leo Kanner's early observations of abnormal head circumference in autistic children. In the past few years, there has been much progress made in elucidating the anatomical and functional abnormalities in ASD. This paper aims to summarise the extant research.

Design/methodology/approach

This paper provides a summary of relevant research findings in the neuroimaging of autism for the past 12 month period. Papers were identified using the Medline search terms: autism; ASD (functional); magnetic resonance imaging (MRI); neuroimaging; diffusion tensor imaging (DTI); and endophenotype.

Findings

Relatively recent techniques such as functional MRI and DTI have furthered the initial work derived from early histological and structural imaging studies. Even newer techniques, such as DTI tractography and support vector machine analysis, and other computer‐based learning methods have allowed us to move beyond regional variations in grey and white matter volume and study ASD as a disorder of connectivity, and of regional cerebral function and neural circuitry. Brain regions and neural circuits that are implicated in the core symptoms of ASD (deficits in social reciprocity, language and communication, and restricted and stereotyped interests) have been repeatedly shown to be abnormal in those individuals.

Originality/value

This paper aims to provide a background for clinicians to the current research and focuses on developments in the field of neuroimaging of ASD from the past year, which have generated further insights into the neurobiology of ASD.

Abstract

Purpose

Due to the excellent functionality of graphene, the research on fiber modification by graphene has been receiving more and more attentions recently, and many research findings have been conducted. However, the purpose of this paper is to focus on the fiber modification method and corresponding modified fiber properties, but the research on processing of the modified fiber, especially the textile process, is little. Therefore, in the paper, the properties of one kind of textile GN fiber and the spinning method of the GN fiber blend yarn and the functionalities of corresponding fabric are studied.

Design/methodology/approach

In the paper, the properties of nylon fiber modified by graphene (GN) were studied first. Then, according to the tested results, one new blending process of the GN fiber and cotton fiber was given, and corresponding properties of the blend yarns were tested and analyzed. Finally, the knitted fabrics were produced using the spun blend yarns, and the antibacterial property, electromagnetic shielding property, anti-ultraviolet performance, anti-static performance and conventional mechanical, and appearance thermal-wet comfort properties were tested and comparatively analyzed.

Findings

The tested results showed that the functionality of all fabrics was effective due to the addition of the graphene in the fiber, especially the antibacterial property. With the increasing of the GN fiber in the blend yarns, the functionality of all fabrics was also increased first and then achieved stability.

Originality/value

One new blending process of the GN fiber and cotton fiber was given. In the spinning, the combed cotton sliver was produced first, and then was torn into small parts of combed cotton sliver fiber by hand. Then, the treated GN fibers and cotton fibers were mixed for the first time, and corresponding GN/C carding sliver was produced. In this blend processing, the mixed cotton fiber was used to improve the sliver processing of the GN fiber. Then, in the drawing process, the required number of GN/C carding sliver and combed cotton sliver were fed simultaneously, and GN fibers and cotton fibers were mixed for the second time, and corresponding four kinds of GN/JC blend yarns were produced. In this blend processing, the mixed cotton fiber was used to regulate the blending ratio.

Abstract

Purpose: Previous research has found that people’s trust in a source of information affects whether they will expose themselves to information from that source, pay attention to that source, and the likelihood that they will act on the information obtained from that source. This study tracked trends in levels of trust in different health information sources over time and investigated sociodemographic predictors of trust in these sources.

Methodology/Approach: Data were drawn from the Health Information National Trends Survey (HINTS), a nationally representative, cross-sectional survey of adults in the USA. Weighted percentages, means, and standard errors for trust in health information sources were computed using data from four iterations of the survey (2005, 2009, 2012, and 2013). Weighted multivariable logistic regression models were employed to investigate associations between sociodemographic variables and level of trust in health information sources using HINTS 2013 data.

Findings: Trend analyses revealed declining trust in “traditional” mass media channels, such as television and radio, for health information and consistently high trust in interpersonal sources, like physicians, over the past decade. Regression analyses showed that those with more education (ORs 2.93–4.59, p < 0.05) and higher incomes (ORs 1.65–2.09, p < 0.05) were more likely to trust the Internet for health information than those with less education and lower incomes. Non-Hispanic Blacks and Hispanics were more likely to trust mass media channels in comparison to Non-Hispanic Whites (ORs 1.73–2.20, p < 0.05).

Implications: These findings can be used to inform the strategic selection of channels for disseminating health information to certain demographic groups.

Abstract

Researchers have discovered that service learning affects students’ academic, personal, and social development. However, currently there is a gap in literature analyzing ways in which service learning affects students’ perceived leadership skills. This study examined the effectiveness of service learning on the perceived leadership skills of 74 sport management undergraduate students at a mid-sized, Midwestern, public university using Kouzes’ and Posner’s Student Leadership Practices Inventory instrument, which examines leadership practices in five areas: Model the Way, Inspire a Shared Vision, Challenge the Process, Enable Others to Act, and Encourage the Heart. The results of this study may help faculty members and administrators to better understand the potential of utilizing service learning projects in their classrooms as a vehicle for their students to develop quality leadership practices. Recommendations for further research and practice are also discussed.

Abstract

Purpose

Public entrepreneurship is increasingly being propounded as a key means of ‘doing more with less’ during the tough times associated with successive rounds of neoliberal restructuring and austerity. The primary aim of this chapter is to provide a critical-exploratory review of sponsorship – a disruptive interjection or particular form of public entrepreneurship.

Methodology/approach

Public entrepreneurship provides a useful theoretical frame for exploring some emergent ways of delivering public services in a post-Credit Crunch global operating environment. Empirical insights are derived from a single local authority in the United Kingdom.

Findings

There is a widespread concern that straitened economic conditions can engender the prevalence of short-term financial considerations at the expense of other objectives. Sponsorship, as a discrete form of public entrepreneurship in some circumstances has the potential to achieve multiple objectives, enriching public value. However, this is contingent of specific contextual factors.

Practical implications

By identifying some risks associated with disruptive interjections intended to open new paths for the sponsorship of public services as well as indicating some opportunities for risk reduction, it is hoped that our analysis may benefit public authorities when they are exploring or evaluating sponsorship ‘opportunities’.

Originality/value

Examining sponsorship through a public entrepreneurship conceptual frame has received limited research attention. Whether sponsorship is a ‘winning solution’ is contingent on the particular form of sponsorship as well as the specific time and place.
