Abstract

Purpose

When researchers find an association between two variables, it is useful to evaluate the role of other constructs in this association. While assessing these mediation effects, it is important to determine if results are equal for different groups. It is possible that the strength of a mediation effect may differ for males and females, for example – such an effect is known as moderated mediation. The paper aims to discuss these issues.

Design/methodology/approach

Participants were 2,532 adolescents from diverse ethnic/racial backgrounds and equally distributed across gender. The goal of this study was to investigate parental respect as a potential mediator of the relationship between gender and delinquency and mental health, and to determine whether observed mediation is moderated by gender.

Findings

Parental respect mediated the association between gender and both delinquency and mental health. Specifically, parental respect was a protective factor against delinquency and mental health problems for both females and males.

Practical implications

Demonstrated the process of estimating models in Lavaan, using two approaches (i.e. single group regression and multiple group regression model), and including covariates in both models.

Originality/value

The authors demonstrate the process of estimating these models in Lavaan, using two approaches, a single group regression model and a multiple group model, and the authors demonstrate how to include covariates in these models.

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 improve the efficiency of dye-sensitized solar cells (DSSCs) which present promising low-cost alternative to the conventional silicon solar cells mainly due to comparatively low manufacturing cost, ease of fabrication and relatively good efficiency. One of the undesirable factor in DSSCs is the electron recombination process that takes place at the transparent conductive oxide/electrolyte interface, on the side of photoelectrode. To reduce this effect in the structure of the solar cell, a TiO2 blocking layer (BL) by atomic layer deposition (ALD) was deposited.

Design/methodology/approach

Scanning electron microscope, Raman and UV-Vis spectroscopy were used to evaluate the influence of BL on the photovoltaic properties. Electrical parameters of manufactured DSSCs with and without BL were characterized by measurements of current-voltage characteristics under standard AM 1.5 radiation.

Findings

The TiO2 BL prevents the physical contact of fluorine-doped tin oxide (FTO) and the electrolyte and leads to increase in the cell’s overall efficiency, from 5.15 to 6.18%. Higher density of the BL, together with larger contact area and improved adherence between the TiO2 layer and FTO surface provide more electron pathways from TiO2 to FTO which facilitates electron transfer.

Originality/value

This paper demonstrates that the introduction of a BL into the photovoltaic device structure is an important step in technology of DSSCs to improve its efficiency. Moreover, the ALD is a powerful technique which allows for the highly reproducible growth of pinhole-free thin films with excellent thickness accuracy and conformality at low temperature.

Abstract

Purpose

The main aim of this paper is to determine how well the UNESCO 2011 Recommendation on Historic Urban Landscape (hereafter, the HUL approach) is understood by the academic community today. It will review relevant research, highlight shortcomings regarding the HUL concept and approach and explore how well the six proposed steps are being considered when implementing the HUL approach.

Design/methodology/approach

This paper presents and discusses the results of a systematic review of 140 peer-reviewed publications, published in international academic journals between 2008 and 2019 and available in databases such as WoS and Scopus, such as journal articles, book chapters and books. More specifically, this research takes the six-step process as its theoretical framework in order to understand if the six steps are being followed in the case studies where the HUL approach has been implemented. Following this, it assesses gaps in the HUL concept and approach. The paper explores the HUL implementation management process, investigating what is being done, how it is being done and who is involved.

Findings

The concept ‘Historic Urban Landscape’ has been used in research since 2008. However, the first case studies implementing the HUL approach were not published until 2013. While there is an abundance of theoretical research in relation to the HUL concept and approach from different perspectives and to varying degrees of depth, the case studies which practically demonstrate the HUL approach and its six steps are scarce. This paper will also show how feasible the steps are and which are used the most.

Originality/value

This research demonstrates if the HUL approach is being understood in the academic field and if the implementation of the six steps is being reflected in the literature. This approach will reveal how these steps are being implemented and if this is having an effect on the heritage planning process.
