Abstract In the Sierra de Guadarrama National Park (central Spain), the population of Iberian wild goat, also known as Spanish ibex (Capra pyrenaica) has grown strongly since its reintroduction three decades ago. The plant community is now under heavy browsing pressure due to this high population. A study of the presence of moss on rocks was used herein as the basis for the design of an indicator, named impact on mosses (im), to describe the environmental pressure exerted by the Iberian wild goat in terms of moss removal. Granite and gneiss zones at medium altitudes with continental Mediterranean climate are the most suitable areas for successful application of the indicator. The hypotheses to test are: (1) the indicator will discriminate between areas with different wild goat pressure levels, (2) wild goat pressure will explain a high proportion of moss loss variance, and (3) the im indicator will be useful to establish a mathematical model between wild goat pressure and moss loss. The proposed indicator was analyzed using both statistical and data science techniques. The results support the mentioned hypotheses. Specifically, statistically significant differences were found regarding the impact on mosses between areas with different levels of Iberian wild goat pressure. Thus, a high proportion of the variance was associated with wild goat pressure (80% for high-pressure areas, 56% for low-pressure areas). A modified parabolic function was fit to express the relationship between Iberian wild goat pressure and impact on mosses. In conclusion, the im indicator was shown to be a useful tool to assess pressure due to Iberian wild goat. Therefore, im can help assess and manage Iberian wild goat populations and determine their sustainable levels.

Abstract This article explores the question, to what degree religiosity contributes, as a protecting factor against a broad category of socially deviant adolescent and youth behaviours. It also tests the hypothesis that gender plays a moderating role in the relationship between religiosity and problem behaviour. It employs a modified version of the Problem Behaviour Syndrome Measure (PBSM), in concert with Jessor and Jessor’s conceptual work. It also makes use of the Duke Religion Index (DUREL) to assess religiosity. The empirical study deals with a representative group of 960 students of upper-secondary schools in the Lubelskie province, Poland. The results were analyzed using canonical analysis and ANOVA. The achievements of the article are twofold. First, it identifies significant correlations between the different levels of religiosity among youth, and the occurrence and intensification of problem behaviours, particularly in regard to organized activity. Organized and intrinsic religiosity play principal protective roles, while the impact of personal religious practices is less significant. Secondly, while analyzing the moderating role of gender in the relationship between religiosity and the intensity of problem behaviour, it was found that gender does not have a significant interactive impact. An affirmative conclusion was confirmed in only two instances.

Existing literature has analysed the relationship between electoral systems and either corruption or satisfaction with democracy (SWD) focussing on the traditional distinction between majoritarian and proportional systems. This paper, instead, investigates if and how specific aspects of electoral systems moderate the negative effects of corruption perceptions on SWD. We argue that two mechanisms act simultaneously but at different levels. The first mechanism is the relationship between voters and the national government, while the second links single representatives to their constituents. We advance conditional hypotheses that postulate an attenuating effect of disproportionality and a reinforcing impact of personal vote. Empirical results from 35 elections in 33 democracies, using both individual and aggregate-level data, confirm the research hypotheses. More disproportional electoral systems weaken the impact of citizens’ perceived corruption on their democratic satisfaction, while this is strengthened by systems in which the ballot control is mostly in the hand of the voters.

The COVID-19 pandemic is having an impact on physical and mental health. Most studies report the impact on mental health and mental distress during the pandemic. As a result of various stressors (such as lockdown, quarantines, and misinformation) there is heightened fear of a pandemic. The sufferer may experience a variety of symptoms of anxiety, depression, and even psychosis. In predisposed vulnerable individuals, fear of COVID-19 is perpetuating pain and dysfunction. This study discussed the ABC framework of fear and influencer to better understand the different levels of symptoms and interventions. There is an urgent need to integrate mental health into primary health-care centers. The attending physician should be aware of the stress disorders associated with the pandemic. This article introduces a handy and practical portrayal of the ABC framework that can be taught to individuals in distress during clinical visits to primary care centers providing awareness of the relationship between thinking, emotional and behavioral responses.

A large part of the school building stock in Andalusia lacks ventilation facilities, so that the air renewal of the classrooms is achieved through the building envelope (air infiltration) or the opening of windows. This research analyses the airtightness of the classrooms in Andalusia and the evolution of CO2 concentration during school hours through in situ monitoring. Pressurization and depressurization tests were performed in 42 classrooms and CO2 concentration was measured in two different periods, winter and midseason, to study the impact of the different levels of aperture of windows. About 917 students (11–17 years of age) were surveyed on symptoms and effects on their health. The mean n50 values are about 7 h−1, whereas the average CO2 concentration values are about 1878 ppm, with 42% of the case studies displaying concentrations above 2000 ppm with windows closed.

Abstract With advances in genomic sequencing technology, a large amount of data is publicly available for the research community to extract meaningful and reliable associations among risk genes and the mechanisms of disease. However, this exponential growth of data is spread in over thousand heterogeneous repositories, represented in multiple formats and with different levels of quality what hinders the differentiation of clinically valid relationships from those that are less well-sustained and that could lead to wrong diagnosis. This paper presents how conceptual models can play a key role to efficiently manage genomic data. These data must be accessible, informative and reliable enough to extract valuable knowledge in the context of the identification of evidence supporting the relationship between DNA variants and disease. The approach presented in this paper provides a solution that help researchers to organize, store and process information focusing only on the data that are relevant and minimizing the impact that the information overload has in clinical and research contexts. A case-study (epilepsy) is also presented, to demonstrate its application in a real context.

Corporate Social Responsibility (CSR) is a concept that describes the relationship between company  and society. The way a company portrays corporate ethics and social initiatives can evoke strong positive reactions among consumers. The emergence of Internet creates a new communicating culture and gives an idea for a company to deliver their CSR message. Applying Media Richness Theory (MRT) in CSR message is believed could facilitate trust among consumer. Thus, this study aims to examine the impact of different level of CSR information richness with consumers trust towards the company. This study divides trust into three components that are competence, benevolence and integrity. An experimental design consisting of different levels of CSR information is selected (rich CSR information, lean CSR information and no CSR information as a control condition). The finding shows that rich CSR information has impacted on competence and integrity but not on benevolence. Result from this study is believed can assist companies in setting up their CSR communicating strategy in engaging consumers’ trust.

Purpose: The purpose of this research paper is to study the influence of transformational leadership on employees' perception of the change and the impact of the different levels of commitment towards change in a semi-conductor multinational company in Malaysia. Design/Methodology/Approach: The partial least squares of structural equation modelling (PLS-SEM) approach was deployed to validate and examine the research theoretical framework, and conduct the hypothesis testing. Findings: The result reveals transformational leadership and employees' perception of the changes to be highly predictive of the employees' commitment with regard to the organizational changes. It also indicates that employees' perception of the change has a significant mediating effect on the relationship between transformational leadership and affective, normative, and continuance commitment. Implications/Originality/Value: Management must be sensitive to employees' reaction for the change initiatives to be successful and it is noteworthy for management to understand the employees' perception of the changes, support their needs.

Abstract The paper aims to analyse the relationship between theatre and crisis from the viewpoint of the role played by the theatre in exploring and presenting extreme situations, namely crisis situations. The impact of crisis on theatre determines the apparition of different theatrical viewpoints which are not meant to offer concrete solutions to the crisis, but which may contribute to the identification of possible ways of solving it due to its capacity to reveal certain aspects of the crisis which manifests itself on different levels of reality. At the same time, this relationship is viewed from the perspective of Antonin Artaud, The Living Theatre, Jerzy Grotowski and Samuel Beckett. Moreover, the paper makes reference to the fact that, in the current pandemic, the theatre performance faces a specific crisis, that is the crisis of audience.

This article is focused on one of the most relevant novelties in the Italian electoral market of the past decade: the emerging phenomenon of intermittent abstentionism. Rather than an increase in overall abstentionism rates, aggregate and survey data show a clear increase in the number of floating voters who swing between voting and non-voting. After a description of the characteristics of intermittent abstensionists, the article discusses the relationship between different electoral systems at different levels of government and territorial differentiation as far as voting participation is concerned. It then discusses the impact of intermittent abstentionism on the results of the 2006 general election where the parties’ electoral campaigns appear to have been aimed at mobilising intermittent abstensionists. The article concludes with some considerations of the Italian electoral cycle, particularly in relation to the changes generated by the run-up to the 2008 elections.

Purpose The purpose of this paper is to investigate the impact that several of these factors have on a consumer’s decision to hold a credit card, as well as those involved in determining the level of credit card limit. Design/methodology/approach Potential explanatory variables were identified in the literature, then used to build a binary logit model to test the impact of the card and consumer characteristics on credit card ownership. Data were collected via a structured interview of 409 consumers living in Hebei Province, China. Findings The results indicate that convenience in use, level of credit card interest rates, the application process, number of people in the household, a rewards programme, marital status, credit limit and age influence the likelihood of the respondent holding a credit card. Further, an anaylsis shows that the number of credit cards held, duration of holding a credit card, monthly credit card purchasing volume and having a degree at the tertiary level, are significantly and positively related to different levels of credit limit. Originality/value In summary, in order to attract more consumers to credit card use, the banks and credit card companies should consider making it more convenient for consumers to use their credit cards. Moreover, banks can increase their networking and degree of cooperation with merchants to increase the acceptance of payment by credit card. The most heavily used businesses such as supermarkets and smaller retailers, where consumers purchase goods frequently, would be good targets for banks’ attention. In addition, banks might also improve credit card reward programmes to make these more efficient and perhaps increase the size of the rewards customers can earn through card use.
