Modeling transpiration and leaf temperature of urban trees – A case study evaluating the microclimate model ENVI-met against measurement data
2018
Abstract Increasing vegetation cover in cities is a key approach to mitigating urban heat excess. However, both the effect of vegetation on microclimate and the plants’ vitality need to be assessed to support and quantify the effects of such strategies. One way to assess the interactions between vegetation and the urban environment is through microclimate models that can simulate the effects of vegetation onto the urban microclimate as well as effects of urban environments onto vegetation. To provide reliable estimates microclimate models need to be parameterized based on empirically obtained data. In this paper we compare modeled transpiration rates and leaf temperatures of a leading micro…
Application of GPS tracking for monitoring spatially unconstrained outdoor recreational activities in protected areas – A case study of ski touring i…
2018
Abstract New trends in leisure and outdoor recreation show an increased penetration of remote areas and the development of spatially unconstrained outdoor recreational activities. Here we present the application of GPS tracking to monitor a spatially unconstrained recreational activity, using ski touring in the Tatra National Park (TNP) as a study case. Particular focus of the study was the spatial and temporal behaviour of ski tourers with regard to existing management measures implemented in the Park, where recreation is limited to designated zones. The research is based upon empirical data (n = 427 ski touring GPS tracks). ArcGIS and statistics software SPSS were used for spatial and sta…
The exploratory factor analysis of items: guided analysis based on empirical data and software
2017
El objetivo del presente trabajo es ilustrar cómo la aplicación adecuada o inadecuada del análisis factorial exploratorio (AFE) puede llevar a conclusiones muy diferentes. Para ello se evalúa el grado en que cuatro paquetes estadísticos diferentes que permiten realizar AFE de ítems, en concreto SPSS, FACTOR, PRELIS y MPlus, permiten o limitan la aplica- ción de los estándares actualmente recomendados en materia de análisis factorial. Asimismo se analizan y comparan los resultados que ofrecen di- chos programas cuando se factorizan datos empíricos de escalas que ajus- tan, según el caso, de manera inadecuada, ambigua u óptima a los supuestos del modelo AFE lineal clásico, a través de las dis…
Entrepreneurial leadership and familiness as resources for strategic entrepreneurship
2012
PurposeThis paper seeks to investigate how familiness and entrepreneurial leadership are related to each other in family firms. Familiness and entrepreneurial leadership are viewed as resources for strategic entrepreneurship. The aim of the paper is to shed light on familiness in three family firms and contribute to the field's growing body of work.Design/methodology/approachThe paper employs a case study method. The interviewees were interviewed by theme questions and secondary information was gathered to strengthen the empirical section. Qualitative interpretation of empirical data was used.FindingsThe findings demonstrate the variety of familiness and entrepreneurial leadership within fa…
Mentoring as Dialogue, Collaboration and/or Assessment?
2012
In this chapter, some tensional trends within mentoring, which we call a contradiction between collaboration and assessment, are addressed. The aim is threefold: First, to describe and compare the development of mentoring programmes in Finland and Sweden at the system level; second, to illustrate how the various mentoring systems have been experienced by the persons involved; and third, to discuss the political and ideological circumstances and the possible effects of these solutions. The study is based on empirical data gathered in Finland and Sweden and examines the experiences of mentors and newly qualified teachers (NQTs) as well as the relevant national policies. The findings indicate …
Immigration, Transition to Parenthood, and Parenting
2018
This chapter adopts a life-course perspective to show how transitioning to parenthood and parenting practices are negotiated and adjusted under the influence of both migrants’ childhoods and migration contexts. The method used for data collection was life-story interviews. For purposes of this study, were selected nine participants, exclusively women. Some mechanisms of parenting formation and transformation were identified by using both inductive and deductive procedures for data analyses. These methods elicited novel information on how women change during migrations with respect to child-rearing and familial patterns. The empirical data suggest that self-change in the case of young migran…
Leaking legitimacies: the Finnish forest sector's entanglement in the land conflicts of Atlantic coastal Brazil
2011
PurposeThe aim of this paper is to focus on the legitimacy problems faced by the Finnish forest industry in the Brazilian context, specifically from the perspective of the region's indigenous communities: the Tupinikim, the Guarani and the Pataxó.Design/methodology/approachThe method used is qualitative research with a case study approach. The empirical data are based on the fieldwork in the states of Espírito Santo and Bahia. The aim was to scrutinize the corporate tactics in gaining societal legitimacy, both in Brazil and in Finland; these were categorized into thematic groups.FindingsThe legitimacy of the Finnish companies becomes questionable due to the unethical tactics of their Brazil…
Liberal and Conservative Differential Item Functioning Detection Using Mantel-Haenszel and SIBTEST: Implications for Type I and Type II Error Rates
2004
The aim of this work was to determine, in terms of Type I and Type II error rates, the risks of applying various statistical procedures for evaluating differential item functioning. To this end, the authors carried out a simulation study in which the Mantel-Haenszel and SIBTEST procedures were applied in conjunction. The variables manipulated were sample size and distribution of ability between groups. Results indicated that, although there was a high rate of agreement between the procedures, the joint Type I and Type II error rate may vary substantially from that obtained when each of the procedures was applied separately. Furthermore, the authors analyzed empirical data to obtain informat…
A Bayesian network model for evacuation time analysis during a ship fire
2013
We present an evacuation model for ships while a fire happens onboard. The model is designed by utilizing Bayesian networks (BN) and then simulated in GeNIe software. In our proposed model, the most important factors that have significant influence on a rescue process and evacuation time are identified and analyzed. By applying the probability distribution of the considered factors collected from the literature including IMO, real empirical data and practical experiences, the trend of the rescue process and evacuation time can be evaluated and predicted using the proposed model. The results of this paper help understanding about possible consequences of influential factors on the security o…
Attracting Major Sporting Events: The Role of Local Residents
2006
Abstract The decision where to host major sports events is the result of a political process, involving local and national politicians as well as national and international sport governing bodies. Politicians and local/national sport governing bodies decide whether to apply for an event, while international sports governing bodies select the host cities (nations). Local and national residents play an important role in this process as their opinion will influence whether the political system supports the application and is willing to fund the event. Many event impacts have characteristics of public goods and externalities. This represents a potential welfare economic rationale for the public…
