Success in the protean career : a predictive study of professional artists and tertiary arts graduatesBridgstock, Ruth Sarah January 2007 (has links)
In the shift to a globalised creative economy where innovation and creativity are increasingly prized, many studies have documented direct and indirect social and economic benefits of the arts. In addition, arts workers have been argued to possess capabilities which are of great benefit both within and outside the arts, including (in addition to creativity) problem solving abilities, emotional intelligence, and team working skills (ARC Centre of Excellence for Creative Industries and Innovation, 2007). However, the labour force characteristics of professional artists in Australia and elsewhere belie their importance. The average earnings of workers in the arts sector are consistently less than other workers with similar educational backgrounds, and their rates of unemployment and underemployment are much higher (Australian Bureau of Statistics, 2005; Caves, 2000; Throsby & Hollister, 2003). Graduating students in the arts appear to experience similar employment challenges and exhibit similar patterns of work to artists in general. Many eventually obtain work unrelated to the arts or go back to university to complete further tertiary study in fields unrelated to arts (Graduate Careers Council of Australia, 2005a). Recent developments in career development theory have involved discussion of the rise of boundaryless careers amongst knowledge workers. Boundaryless careers are characterised by non-linear career progression occurring outside the bounds of a single organisation or field (Arthur & Rousseau, 1996a, 1996b). The protean career is an extreme form of the boundaryless career, where the careerist also possesses strong internal career motivations and criteria for success (Baruch, 2004; Hall, 2004; Hall & Mirvis, 1996). It involves a psychological contract with one's self rather than an organisation or organisations. The boundaryless and protean career literature suggests competencies and dispositions for career self-management and career success, but to date there has been minimal empirical work investigating the predictive value of these competencies and dispositions to career success in the boundaryless or protean career. This program of research employed competencies and dispositions from boundaryless and protean career theory to predict career success in professional artists and tertiary arts graduates. These competencies and dispositions were placed into context using individual and contextual career development influences suggested by the Systems Theory Framework of career development (McMahon & Patton, 1995; Patton & McMahon, 1999, 2006a). Four substantive studies were conducted, using online surveys with professional artists and tertiary arts students / graduates, which were preceded by a pilot study for measure development. A largely quantitative approach to the program of research was preferred, in the interests of generalisability of findings. However, at the time of data collection, there were no quantitative measures available which addressed the constructs of interest. Brief scales of Career Management Competence based on the Australian Blueprint for Career Development (Haines, Scott, & Lincoln, 2003), Protean Career Success Orientation based on the underlying dispositions for career success suggested by protean career theory, and Career Development Influences based on the Systems Theory Framework of career development (McMahon & Patton, 1995; Patton & McMahon, 1999, 2006a) were constructed and validated via a process of pilot testing and exploratory factor analyses. This process was followed by confirmatory factor analyses with data collected from two samples: 310 professional artists, and 218 graduating arts students who participated at time 1 (i.e., at the point of undergraduate course completion in October, 2005). Confirmatory factor analyses via Structural Equation Modelling conducted in Study 1 revealed that the scales would benefit from some respecification, and so modifications were made to the measures to enhance their validity and reliability. The three scales modified and validated in Study 1 were then used in Studies 3 and 4 as potential predictors of career success for the two groups of artists under investigation, along with relevant sociodemographic variables. The aim of the Study 2 was to explore the construct of career success in the two groups of artists studied. Each participant responded to an open-ended question asking them to define career success. The responses for professional artists were content analysed using emergent coding with two coders. The codebook was later applied to the arts students' definitions. The majority of the themes could be grouped into four main categories: internal definitions; financial recognition definitions; contribution definitions; and non-financial recognition definitions. Only one third of the definition themes in the professional artists' and arts graduates' definitions of career success were categorised as relating to financial recognition. Responses within the financial recognition category also indicated that many of the artists aspired only to a regular subsistence level of arts income (although a small number of the arts graduates did aspire to fame and fortune). The second section of the study investigated the statistical relationships between the five different measures of career success for each career success definitional category and overall. The professional artists' and arts graduates' surveys contained several measures of career success, including total earnings over the previous 12 months, arts earnings over the previous 12 months, 1-6 self-rated total employability, 1-6 self-rated arts employability, and 1-6 self-rated self-defined career success. All of the measures were found to be statistically related to one another, but a very strong statistical relationship was identified between each employability measure and its corresponding earnings measure for both of the samples. Consequently, it was decided to include only the earnings measures (earnings from arts, and earnings overall) and the self-defined career success rating measure in the later studies. Study 3 used the career development constructs validated in Study 1, sociodemographic variables, and the career success measures explored in Study 2 via Classification and Regression Tree (CART - Breiman, Friedman, Olshen, & Stone, 1984) style decision trees with v-fold crossvalidation pruning using the 1 SE rule. CART decision trees are a nonparametric analysis technique which can be used as an alternative to OLS or hierarchical regression in the case of data which violates parametric statistical assumptions. The three optimal decision trees for total earnings, arts earnings and self defined career success ratings explained a large proportion of the variance in their respective target variables (R2 between 0.49 and 0.68). The Career building subscale of the Career Management Competence scale, pertaining to the ability to manage the external aspects of a career, was the most consistent predictor of all three career success measures (and was the strongest predictor for two of the three trees), indicating the importance of the artists' abilities to secure work and build the external aspects of a career. Other important predictors included the Self management subscale of the Career Management Competence scale, Protean Career Success Orientation, length of time working in the arts, and the positive role of interpersonal influences, skills and abilities, and interests and beliefs from the Career Development Influences scale. Slightly different patterns of predictors were found for the three different career success measures. Study 4 also involved the career development constructs validated in Study 1, sociodemographic variables, and the career success measures explored in Study 2 via CART style decision trees. This study used a prospective repeated measures design where the data for the attribute variables were gathered at the point of undergraduate course completion, and the target variables were measured one year later. Data from a total of 122 arts students were used, as 122 of the 218 students who responded to the survey at time 1 (October 2005) also responded at time 2 (October 2006). The resulting optimal decision trees had R2 values of between 0.33 and 0.46. The values were lower than those for the professional artists' decision trees, and the trees themselves were smaller, but the R2 values nonetheless indicated that the arts students' trees possessed satisfactory explanatory power. The arts graduates' Career building scores at time 1 were strongly predictive of all three career success measures at time 2, a similar finding to the professional artists' trees. A further similarity between the trees for the two samples was the strong statistical relationship between Career building, Self management, and Protean Career Success Orientation. However, the most important variable in the total earnings tree was arts discipline category. Technical / design arts graduates consistently earned more overall than arts graduates from other disciplines. Other key predictors in the arts graduates' trees were work experience in arts prior to course completion, positive interpersonal influences, and the positive influence of skills and abilities and interests and beliefs on career development. The research program findings represent significant contributions to existing knowledge about artists' career development and success, and also the transition from higher education to the world of work, with specific reference to arts and creative industries programs. It also has implications for theory relating to career success and protean / boundaryless careers.

Small and medium enterprise financing and credit rationing : the role of banks in South AfricaMutezo, Ashley Teedzwi 06 1900 (has links)
The potential of small and medium enterprises (SMEs) in promoting economic growth in both developed and developing countries is widely accepted and documented by both scholars and policy makers. Particularly lacking are studies on the evidence in support of the importance of credit rationing to the sustainability of SMEs in an emerging economy like South Africa’s. This specific problem, especially in the developing countries, has been identified as the major bottleneck in realising socio-economic potentials of SMEs in those countries. However, one of the major ways of addressing the challenge of inadequate funding that exists within the SME sector is the use of bank credit. This study was therefore undertaken to explore the role of commercial banks in the provision of credit to the SMEs in South Africa.
This study focuses on the issue of the relationship between the banking industry and SMEs. In particular, the problem of credit rationing of, and discrimination against SMEs by commercial banks was investigated. Because credit rationing and finance gaps can stem from imperfections on either supply-side (banks), or demand-side (SMEs), or both, the intention of the study was to examine both of these variables in order to uncover the implications of their relationships.
The empirical analysis is based on survey data collected by means of a structured questionnaire which was distributed amongst banks and SME borrowers in the Gauteng Province of South Africa. Contrary to the general view that commercial banks are disinclined to provide credit to SMEs, the study found that South African banks are keen to serve the SMEs and are therefore making efforts to penetrate this potentially profitable market segment. However, several obstacles are potentially restricting the involvement of banks with SMEs in South Africa. The findings revealed that regulations such as the Financial Intelligence Centre Act (FICA) and the National Credit Act (NCA) came out strongly as major hindrances of bank financing to SMEs. Furthermore, it was shown that compliance with the NCA was ranked higher than credit history and profitability as a factor hindering the approval of SME loans.
- iii -
However, by using the structural equation modelling (SEM), the results also show that there is a positive and significant influence of lending technology and collateral on the supply of credit to SMEs. Variables such as creditworthiness, collateral and e-banking were found to have a positive and significant impact on the provision of credit to SMEs by commercial banks. For both the supply- and demand-side analysis, technology came out as the most important predictor of SME access to finance. This means that banks should strive to align their lending techniques with the dynamic technological developments so as to reach as many SMEs as possible even in the geographically dispersed regions. It is anticipated that improving SME access to bank credit could be the key to the growth and sustainability of SMEs, the alleviation of poverty and unemployment; and consequently leading to the growth of the South African economy. / Business Management / D.

Psychological and social factors related to physical science achievement and attitude of secondary school studentsMashile, Elias Oupa, 1963- 07 1900 (has links)
School physical science is a prerequisite for science courses at institutions of higher education. Science
graduates are an important link in a nation's scientific and technological development which often
shapes a country's economic development. The purpose of this study was to investigate psychological
and social factors influencing physical science achievement and attitude of black secondary school
students in South Africa.
The first part of the literature study which was concerned with physical science education in South Africa
revealed that few black students chose to study science after standard seven, that failure rates were high
and that science education was generally in a state of crisis. The second part of the literature study
identified psychological and social factors related to science achievement and attitude. These were
home environment variables, teacher and school related variables, personal variables (self-concept,
motivation, gender, ethnicity) and students' abilities. The third part was the construction of a Structural
Equation Model (SEM) specifying the relationships among the psychological and social factors and their
effects on physical science achievement and attitude.
The theoretical SEM fit the data reasonably well. The best fitting model, however, was a revised model
in which several paths were constrained. The latter accounted for a substantial variance in attitude
towards physical science (70.3%) and a meagre 17.7% in physical science achievement.
The variables ability, home environment and self-concept had the greatest total effects on physical
science achievement. Self-concept, home environment and motivation made the greatest total
contributions to physical science attitude. Teacher characteristics and school environment had non-significant
effects on physical science achievement and attitude. Multiple-group structural equation modelling analyses found no significant difference in the structural parameters of boys and girls. Theoretical and educational implications of the findings were discussed and specific recommendations
for improving educational practice in general and physical science achievement and attitude in particular,
were made. / Psychology of Education / D. Ed. (Psychology of Education)

Health risks of distance running: modelling the predictors of running addiction, overuse injuries, and infectious illnessStruwig, Gillian Anne 02 1900 (has links)
Text in English / Regular exercise has significant physical and psychological health benefits yet, paradoxically, may also have harmful effects. The purpose of this study was to investigate the physical and psychological health risks of distance running, a popular participation sport in South Africa. Structural equation modelling was employed to examine the personality and motivational antecedents of running addiction and its influence, in turn, on self-reported overuse injuries and upper respiratory tract infections in 220 athletic club members. The predictors and physical health effects of customary training load were also assessed. It was found that perfectionistic concerns, Type A behaviour pattern, and task goal orientation had a direct, positive impact on running addiction, which predicted higher running injury scores. In contrast, training workload (Volume × Intensity) was inversely related to injury risk. Neither running addiction nor any training load variables influenced infectious illness susceptibility. The findings of this study indicate that maladaptive perfectionism, Type A behaviour, and achievement goal orientation may be risk factors for running addiction, which may, in turn, contribute to increased injury incidence in South African distance runners. Conversely, heavier training loads may be protective against injury occurrences in this population. The results of this research may help to enhance current understanding of the possible health hazards of distance running. This knowledge may have practical implications for the health and well-being of runners of diverse levels of ability and experience. / Psychology / D.Litt. et Phil. (Psychology)

Development and validation of a hybrid measure of organisational communication satisfactionAmanuel Gebru Woldearegay, Woldearegay, Amanuel Gebru 06 1900 (has links)
The purpose of the study was to identify and transform, as necessary, constructs
of communication satisfaction and to develop a hybrid quantitative audit of
organisational communication satisfaction for collectivist contexts that is both
reliable and valid, using Amos Graphics for structural equation modelling. The
objective was also to develop a full latent variable model and to test its fitness to
the data collected from a random sample of civil servants across Addis Ababa’s
civil service bureaus.
The study comprised three sequential parts, namely pilot, exploratory factor
analysis (EFA) (Main Study One) and confirmatory factor analysis (CFA) (Main
Study Two). These were used as per the existing framework in instrument
development and validation. The pilot study indicated the need for more robust
data. After a series of tests, principal factor axis factoring with oblique rotation
was used as the most appropriate for perceptual data, out of several options on
the EFA menu. The initially hypothesised six-factor solution with the dimensions
of horizontal communication, personal feedback, supervisory communication,
communication climate, relational trust and job satisfaction was found to be unfit
for the data on conceptual and statistical grounds and psychometric analyses
which involved the use of eigenvalues and the scree plot.
A more appropriate two-factor solution based on the more precise parallel
analysis strategy was consistent with current research that communication
satisfaction is best conceptualised in terms of informational and relational
domains as operationalised using the EFA procedure. The two-factor solution led
to the formation of a 17-item scale out of the original 30-item measure, with two
latent dimensions namely relational satisfaction and informational satisfaction.
The items of the new EFA-generated organisational communication satisfaction
scale were renumbered consecutively and the scale was cross-validated on a
xiv
new sample of 288 civil servants from the Addis Ababa City Administration. The
cross-validation necessitated model respecification and re-estimation.
The respecified model underwent validation at different levels. All seven aspects
of validity, namely content validity, construct validity, factorial validity, reliability,
convergent validity, discriminant validity and nomological validity, were
addressed and found to be adequate. However limitations are also indicated as
avenues for further enquiry. / Communication Science / D. Litt. et Phil. (Communication)

How brand function and corporate image create loyalty in North America, Europe, and Africa's Telecom service providersMohlala, Clene 01 1900 (has links)
Brand loyalty is seen as a repeat purchase and also the ability to recommend services or products. Telecommunication service providers require loyal customers to stay in business.
The current thesis examines the impact of how brand function and corporate image create loyalty in North America, Europe, and Africa's telecom service providers. The researcher employed an anonymous online survey in Africa, Europe, and North America. A total of 971
responses were received. Using Partial Least Square regression analysis, the research examined the relationship between the variables: Brand Function, Corporate Image and Loyalty. The
study found that brand function and corporate image has a significant positive effect on customer satisfaction. In addition, the research used machine learning algorithm to model the best prediction for consumer recommendation of products and services through their
telecommunication service provider to friends and family. / School of Computing / M. Sc. (Computing)

Measuring Mobile Collaborative Learning and academic achievement : whatsapp and students in South AfricaNyembe, Bangisisi Zamuxolo Mathews 01 1900 (has links)
Mobile learning has developed into an essential component within the education landscape and, with two billion users worldwide, the social media platform WhatsApp has become a prominent feature in this domain. Nevertheless, with ambiguity in the literature about the effects of WhatsApp on teaching and learning and especially a paucity of research measuring collaboration on WhatsApp in relation to students’ academic achievement. The purpose of the study was to explain and predict WhatsApp’s effect on academic achievement using a quantitative questionnaire. The results suggest that increased collaboration on WhatsApp may improve academic achievement. Additionally, improving other aspects, such as active learning, trust, support, formality, interaction and interdependence, may enhance collaboration and, in turn, improve academic achievement. The study has value by providing measurable scientific evidence about the effects of WhatsApp on learning that can be incorporated into the design of teaching and learning activities with WhatsApp to improve academic achievement. / Uhlelo lokufunda uhamba (Mobile learning) selikhule ladlondlobala laba yisigaba esibalulekile ngaphansi komkhakha wemfundo kanti, lolu hlelo selunabasebenzisi abangamabhiliyoni amabili emhlabeni wonke jikelele, uhlelo lwenkundla yezokuxhumana komphakathi lwe-WhatsApp seluyinkanyezi egqamile kulesi sizinda.

Approche bayésienne de l'évaluation de l'incertitude de mesure : application aux comparaisons interlaboratoires / Bayesian approach for the evaluation of measurement uncertainty applied to interlaboratory comparisonsDemeyer, Séverine 04 March 2011 (has links)
La modélisation par équations structurelles est très répandue dans des domaines très variés et nous l'appliquons pour la première fois en métrologie dans le traitement de données de comparaisons interlaboratoires. Les modèles à équations structurelles à variables latentes sont des modèles multivariés utilisés pour modéliser des relations de causalité entre des variables observées (les données). Le modèle s'applique dans le cas où les données peuvent être regroupées dans des blocs disjoints où chaque bloc définit un concept modélisé par une variable latente. La structure de corrélation des variables observées est ainsi résumée dans la structure de corrélation des variables latentes. Nous proposons une approche bayésienne des modèles à équations structurelles centrée sur l'analyse de la matrice de corrélation des variables latentes. Nous appliquons une expansion paramétrique à la matrice de corrélation des variables latentes afin de surmonter l'indétermination de l'échelle des variables latentes et d'améliorer la convergence de l'algorithme de Gibbs utilisé. La puissance de l'approche structurelle nous permet de proposer une modélisation riche et flexible des biais de mesure qui vient enrichir le calcul de la valeur de consensus et de son incertitude associée dans un cadre entièrement bayésien. Sous certaines hypothèses l'approche permet de manière innovante de calculer les contributions des variables de biais au biais des laboratoires. Plus généralement nous proposons un cadre bayésien pour l'amélioration de la qualité des mesures. Nous illustrons et montrons l'intérêt d'une modélisation structurelle des biais de mesure sur des comparaisons interlaboratoires en environnement. / Structural equation modelling is a widespread approach in a variety of domains and is first applied here to interlaboratory comparisons in metrology. Structural Equation Models with latent variables (SEM) are multivariate models used to model causality relationships in observed variables (the data). It is assumed that data can be grouped into separate blocks each describing a latent concept modelled by a latent variable. The correlation structure of the observed variables is transferred into the correlation structure of the latent variables. A Bayesian approach of SEM is proposed based on the analysis of the correlation matrix of latent variables using parameter expansion to overcome identifiability issues and improving the convergence of the Gibbs sampler. SEM is used as a powerful and flexible tool to model measurement bias with the aim of improving the reliability of the consensus value and its associated uncertainty in a fully Bayesian framework. The approach also allows to compute the contributions of the observed variables to the bias of the laboratories, under additional hypotheses. More generally a global Bayesian framework is proposed to improve the quality of measurements. The approach is illustrated on the structural equation modelling of measurement bias in interlaboratory comparisons in environment.

Perceptions of Landscape Services Provided by Urban Green Infraestructure. The Case Study of a Campus Open SpaceTudorie, Carla Ana-Maria 11 July 2024 (has links)
[ES] La infraestructura verde urbana ha surgido como un instrumento de excelencia del campus, que puede mejorar la calidad de las funciones y servicios suministrados, y fortalecer las relaciones entre el campus y la comunidad universitaria, y entre el campus y la ciudad. Los miembros de la comunidad universitaria interactúan a menudo con el paisaje del campus y experimentan un cierto nivel de satisfacción con los beneficios derivados de la gestión de los espacios abiertos. En la literatura, estos beneficios se conocen como servicios del paisaje. El perfil del usuario y los parámetros físicos del espacio juegan un papel crucial en la determinación de las funciones y servicios percibidos, lo que se refleja en la preferencia y en el uso del espacio por parte del público.
Esta tesis contribuye al conocimiento de las relaciones entre las personas y su entorno exterior cercano en el contexto del paisaje del campus universitario de la Universitat Politècnica de València. El objetivo del estudio es evaluar la funcionalidad de la infraestructura verde urbana en el entorno del campus. Además, la tesis tiene como objetivo comprender cómo la percepción y la satisfacción están mediadas por el perfil de los miembros de la comunidad universitaria, y cómo se relacionan los servicios con la satisfacción. Esta investigación examina si las tipologías actuales de los espacios abiertos del campus satisfacen las preferencias de los miembros de la comunidad universitaria.
Para llevar a cabo esta investigación, se ha diseñado una encuesta online. Se ha construido un modelo de ecuaciones estructurales para identificar las relaciones entre la oferta percibida de servicios del paisaje, el perfil de los encuestados y la satisfacción. Se han realizado regresiones lineales y análisis de rutas para analizar las preferencias de los encuestados por los espacios abiertos y explorar las relaciones entre los servicios del paisaje.
Los resultados revelan que los encuestados perciben los espacios abiertos del campus principalmente por sus beneficios como proporcionar un espacio para relajarse, socializar con amigos y transitar. La edad, el género, la rama de conocimiento, la frecuencia de uso y la preferencia por el espacio abierto son factores que influyen en la calidad percibida de los servicios de paisaje. Los miembros de la comunidad universitaria prefieren usar espacios abiertos más grandes que se encuentren cerca de las áreas comunes y que brindan fácil acceso a los servicios e instalaciones del campus. Las características que principalmente condicionan la preferencia del espacio son la topografía variada del espacio, la diversidad de árboles y el mobiliario urbano bien equipado.
Este trabajo contribuye al conocimiento sobre cómo las variables psicosociales, como la preferencia, la percepción y el uso, se pueden aplicar de manera efectiva en la planificación y el diseño de espacios abiertos. Además, los resultados son útiles no solo para las universidades, sino también para todos los elementos de la infraestructura verde urbana que aún no tienen un diseño de paisaje multifuncional y se están adaptando a las necesidades de sus usuarios. / [CA] La infraestructura verda urbana ha sorgit com un instrument d'excel·lència del campus, que desitja millorar la qualitat de les funcions i serveis subministrats, i enfortir les relacions entre el campus i la comunitat universitària, i entre el campus i la ciutat. Els membres de la comunitat universitària interactuen sovint amb el paisatge del campus i experimenten un cert nivell de satisfacció amb els beneficis que brinda la gestió dels espais oberts. En la literatura, aquests beneficis es coneixen com a serveis del paisatge. El perfil del públic i els paràmetres físics de l'espai juguen un paper crucial en la determinació de les funcions i serveis subministrats percebuts, la qual cosa es reflecteix en la preferència i en l'ús de l'espai per part del públic.
Aquesta tesi contribueix al coneixement de les relacions entre les persones i el seu entorn exterior pròxim en el context del paisatge del campus universitari de la Universitat Politècnica de València. L'objectiu de l'estudi és avaluar la funcionalitat de la infraestructura verda urbana a l'entorn del campus. A més, la tesi té com a objectiu comprendre com la percepció i la satisfacció estan mediades pel perfil dels membres de la comunitat universitària, i com es relacionen els serveis amb la satisfacció. Aquesta investigació examina si les tipologies actuals dels espais oberts del campus satisfan les preferències dels membres de la comunitat universitària.
Per a dur a terme aquesta investigació, s'ha dissenyat una enquesta en línia. S'ha construït un model d'equacions estructurals per a identificar les relacions entre l'oferta percebuda de serveis del paisatge, el perfil dels enquestats i la satisfacció. S'han realitzat regressions lineals i anàlisis de rutes per a analitzar les preferències dels enquestats pels espais oberts i explorar les relacions entre els serveis del paisatge.
Els resultats revelen que els enquestats perceben els espais oberts del campus principalment pels seus beneficis com proporcionar un espai per a relaxar-se, socialitzar amb amics i passar. L'edat, el gènere, la branca de coneixement, la freqüència d'ús i la preferència per l'espai obert són factors que influeixen en la qualitat percebuda dels serveis de paisatge. Els membres de la comunitat universitària prefereixen usar espais oberts més grans que es troben prop de les àrees comunes i que brinden fàcil accés als serveis i instal·lacions del campus. Les característiques rellevants per a la preferència de l'espai són la topografia variada de l'espai, la diversitat d'arbres i el mobiliari urbà ben equipat.
Aquesta investigació contribueix al coneixement sobre com les variables psicosocials, com la preferència, la percepció i l'ús, es poden aplicar de manera efectiva en la planificació i el disseny d'espais oberts. A més, els resultats són útils no sols per a les universitats, sinó també per a tots els elements de la infraestructura verda urbana que encara no tenen un disseny de paisatge multifuncional i s'estan adaptant a les necessitats dels seus usuaris. / [EN] Urban green infrastructure has emerged as a campus excellency instrument, which is desired to improve the quality of provided functions and services, and strengthen the relationships between campus and university community, and between campus and city. The university community members often interact with the campus landscape and experience a certain level of satisfaction with the benefits provided by the management of open space. In the literature, these benefits are known as landscape services. The public¿s profile and space physical parameters play a crucial role in determining the functions and perceived supplied services, which echoes in the public¿s preference and use of space.
This thesis contributes to the knowledge of the relationships between people and their close outdoor environment in the context of the university campus landscape of Universitat Politècnica de València. The aim of the study is to assess the functionality of urban green infrastructure within the campus setting. Furthermore, the thesis aims to understand how perceptions and satisfaction are mediated by the university community profile, and how services and satisfaction are related. This research examines whether the current typologies of campus open spaces meet the preferences of university community members.
To conduct this research, an online survey has been designed. A structural equation model has been built to identify the relationships between the perceived supply of landscape services, respondents¿ profile and satisfaction. Linear regression and path analysis have been conducted to analyse respondents' preferences for open space and explore the relationships among landscape services.
Results highlight that respondents perceive campus open spaces mainly for its benefits such as providing a space for relaxation, socialising with friends and passing through. Age, gender, branch of knowledge, frequency of use and preference for open space are factors influencing the perceived quality of landscape services. University community members prefer using larger open spaces that are placed close to common areas and provide easy access to campus services and facilities. When it comes to preference, varied space topography, diversity of trees and well-equipped urban furniture, are relevant features.
This research contributes to the knowledge on how psychosocial variables such as preference, perceptions and use, can be effectively applied in open space planning and design. Moreover, the results are helpful not only for universities, but also for all elements of urban green infrastructure that have yet to have a multifunctional landscape design and are adapting to the needs of their users. / I am grateful for the support of the Universitat Politècnica de València and the
