Propuesta metodológica de aplicación sectorial de Análisis de Ciclo de Vida (ACV) para la evaluación ambiental de la edificación en España

La aplicación de criterios de sostenibilidad ha de entenderse como el procedimiento esencial para la necesaria reconversión del sector de la construcción, que movilizando el 10% de la economía mundial, representa más de la tercera parte del consumo mundial de recursos, en torno al 30-40% del consumo energético y emisiones de gases de efecto invernadero, 30-40% de la generación de residuos y el 12% de todo el gasto en agua dulce del planeta. La presente investigación se enmarca en una estrategia general de promover la evaluación de la sostenibilidad en la edificación en el contexto español, dando un primer paso centrado en la evaluación del comportamiento ambiental. El hilo conductor de la investigación parte de la necesidad de establecer un marco teórico de sostenibilidad, que permita clarificar conceptos y definir criterios de valoración adecuados. Como siguiente paso, la investigación se dirige a la revisión del panorama internacional de normativa e instrumentos voluntarios, con el objetivo de clarificar el difuso panorama que caracteriza a la sostenibilidad en el sector de la edificación en la actualidad y enmarcar la investigación en un contexto de políticas y programaciones ya existentes. El objetivo principal reside en el planteamiento de una metodología de evaluación de los aspectos o impactos ambientales asociados al ciclo de vida de la edificación, aplicable al contexto español, como una de las tres dimensiones que constituyen los pilares básicos de la sostenibilidad. Los ámbitos de evaluación de los aspectos sociales y económicos, para los que no existe actualmente un grado de definición metodológico suficientemente congruente, son adicionalmente examinados, de cara a ofrecer una visión holística de la evaluación. Previo al desarrollo de la propuesta, se aborda, en primer lugar, la descripción de las características básicas y limitaciones de la metodología de Análisis de Ciclo de Vida (ACV), para posteriormente proceder a profundizar en el estado del arte de aplicación de ACV a la edificación, realizando una revisión crítica de los trabajos de investigación que han sido desarrollados en los últimos años. Esta revisión permite extraer conclusiones sobre su grado de coherencia con el futuro entorno normativo e identificar dos necesidades prioritarias de actuación: -La necesidad de armonización, dadas las fuertes inconsistencias metodológicas detectadas, que imposibilitan la comparación de los resultados obtenidos en los trabajos de evaluación. -La necesidad de simplificación, dada la complejidad inherente a la evaluación, de modo que, manteniendo el máximo rigor, sea viable su aplicación práctica en el contexto español. A raíz de la participación en los trabajos de desarrollo normativo a nivel europeo, se ha adquirido una visión crítica sobre las implicaciones metodológicas de la normativa en definición, que permite identificar la hoja de ruta que marcará el escenario europeo en los próximos años. La definición de la propuesta metodológica integra los principios generales de aplicación de ACV con el protocolo metodológico establecido en la norma europea, considerando adicionalmente las referencias normativas de las prácticas constructivas en el contexto español. En el planteamiento de la propuesta se han analizado las posibles simplificaciones aplicables, con el objetivo de hacer viable su implementación, centrando los esfuerzos en la sistematización del concepto de equivalente funcional, el establecimiento de recomendaciones sobre el tipo de datos en función de su disponibilidad y la revisión crítica de los modelos de cálculo de los impactos ambientales. Las implicaciones metodológicas de la propuesta se describen a través de una serie de casos de estudio, que ilustran su viabilidad y las características básicas de aplicación. Finalmente, se realiza un recorrido por los aspectos que han sido identificados como prioritarios en la conformación del escenario de perspectivas futuras, líneas de investigación y líneas de acción. Abstract Sustainability criteria application must be understood as the essential procedure for the necessary restructuring of the construction sector, which mobilizes 10% of the world economy, accounting for more than one third of the consumption of the world's resources, around 30 - 40% of energy consumption and emissions of greenhouse gases, 30-40% of waste generation and 12% of all the fresh water use in the world. This research is in line with an overall strategy to promote the sustainability assessment of building in the Spanish context, taking a first step focused on the environmental performance assessment. The thread of the present research sets out from the need to establish a theoretical framework of sustainability which clarifies concepts and defines appropriate endpoints. As a next step, the research focuses on the review of the international panorama regulations and voluntary instruments, with the aim of clarifying the fuzzy picture that characterizes sustainability in the building sector at present while framing the research in the context of existing policies and programming. The main objective lies in the approach of a methodology for the assessment of the environmental impacts associated with the life cycle of building, applicable to the Spanish context, as one of the three dimensions that constitute the pillars of sustainability. The areas of assessment of social and economic issues, for which there is currently a degree of methodological definition consistent enough, are further examined, in order to provide a holistic view of the assessment. The description of the basic features and limitations of the methodology of Life Cycle Assessment (LCA) are previously addressed, later proceeding to deepen the state of the art of LCA applied to the building sector, conducting a critical review of the research works that have been developed in recent years. This review allows to establish conclusions about the degree of consistency with the future regulatory environment and to identify two priority needs for action: - The need for harmonization, given the strong methodological inconsistencies detected that prevent the comparison of results obtained in assessment works. - The need for simplification, given the inherent complexity of the assessment, so that, while maintaining the utmost rigor, make the practical application feasible in the Spanish context. The participation in the work of policy development at European level has helped to achieve a critical view of the methodological implications of the rules under debate, identifying the roadmap that will mark the European scene in the coming years. The definition of the proposed methodology integrates the general principles of LCA methodology with the protocol established in the European standard, also considering the regulatory standards to construction practices in the Spanish context. In the proposed approach, possible simplifications applicable have been analyzed, in order to make its implementation possible, focusing efforts in systematizing the functional equivalent concept, establishing recommendations on the type of data based on their availability and critical review of the calculation models of environmental impacts. The methodological implications of the proposal are described through a series of case studies, which illustrate the feasibility and the basic characteristics of its application. Finally, the main aspects related to future prospects, research lines and lines of action that have been identified as priorities are outlined.

Objetos tenaces : adaptive reuse en Meatpacking, 1970–1985

OBJETOS TENACES versa sobre la práctica del adaptive reuse (la “reutilización adaptativa”, la reconversión) explicado a través del fenómeno de ruptura, suspensión y reconfiguración de vínculos que el objeto arquitectónico tiene con respecto a su medio económico, sociocultural, normativo y de utilitas. Se trata de un fenómeno en tres fases, muy próximo al mecanismo empleado por el readymade y por el display, que en arquitectura parte de la crisis que supone un cambio de circunstancias, un desarraigo del objeto respecto de su ámbito anterior. El mecanismo tiene vocación de intervención mínima, desde un posicionamiento actual que comprende el mundo construido como una realidad “ya hecha”, y donde las operaciones de proyecto son acciones de transformación que llevan de una situación de obsolescencia a otra de vigencia renovada, es decir, de una realidad completa a otra igualmente completa. Para ello, la investigación se sirve de tres ejemplos de un mismo entorno geográfico (el área en torno a Meatpacking, en el lado oeste del bajo Manhattan, Nueva York) y temporal (las últimas décadas del siglo XX, en las que los casos se solapan a pesar de tener desarrollos cronológicos diversos). Bell Telephone Laboratories, The West Side Improvement y The National Biscuit Company, reconvertidos a Westbeth, a The High Line y a Chelsea Market, construyen juntos el argumento por suma de conceptos, por adición de fenómenos, estudiando las cualidades y las circunstancias que hacen posible la continuidad de las estructuras, es decir, su supervivencia. El texto forma un corpus que proporciona algunas de las claves del objeto denominado como tenaz a través del análisis sincrónico del antes y el después de su puesta en crisis. A tal efecto, se exponen una serie de figuras razonadas entre las cuales figuran el lijado del barniz, los hilos compartidos, la máscara, la momificación y la vitrina, el puente sobre le desfiladero, el enfriamiento, o las reliquias, incrustaciones y adherencias, todas ellas encaminadas a explicar el proceso de renovación del artefacto como un cambio en el sentido, en el significado, y no tanto en lo material. Entre las consideraciones de la tesis está, por un lado, el carácter relativo del término tenacidad, concepto que define a los objetos que se encuentran y se reconocen en su idoneidad, que tienen capacidad de adaptación, y que precisan finalmente de grandes dosis de pragmatismo para su reconfiguración, siendo todas éstas condiciones necesarias pero sólo suficientes a posteriori. Por otro lado, el texto reflexiona acerca del intangible que comparten todos los objetos así llamados y que consiste en la condición, quizá formidable, de ser reconocibles por parte de los sucesivos intervinientes de su historia, convencidos de que su renovación supone una oportunidad; su desaparición, una pérdida. Finalmente, la investigación apunta hacia el concepto de anacronismo como justificación para los objetos que se demuestran adaptables a épocas sucesivas, y que encajan en el tiempo de forma compleja. ABSTRACT TENACIOUS OBJECTS deals with the practice of the adaptive reuse explained by means of the phenomenon of rupture, suspension and reconfiguration of links that the architectural object has vis-à-vis its economic, socio-cultural and regulatory environment, and its utilitas. It is a phenomenon structured in three stages, very close to the mechanism used by the readymade and by the display, which in architecture arise from the crisis that leads to a change in circumstances, an alienation of the object regarding its previous environment. The mechanism aims to the minimum intervention, from a current positioning which understands the world built as a reality “already made”, and where the operations of the project are transformative actions that take us from a situation of obsolescence to a situation of renewed validity, that is, from a complete reality to one just as complete. For this purpose, the research makes use of three examples in the same geographical area (the Meatpacking Discrict, in the Lower West Side of Manhattan, New York) and the same period (the last decades of the 20th century, in which the cases overlap in spite of their diverse chronological developments). Bell Telephone Laboratories, The West Side Improvement and The National Biscuit Company, reconverted into Westbeth, The High Line and Chelsea Market, make up, together, the argument as a sum of concepts, and addition of phenomena, studying the qualities and circumstances which make the continuity of the structures possible, that is, their survival. The text forms a corpus that provides some of the keys of the so-called tenacious object by means of the synchronic analysis of before and after its crisis. To this end, a series of reasoned figures is presented, including the sanding of varnish, the shared threads, the mask, the mummification and the display cabinet, the bridge over the gorge, cooling, or the relics, incrustations and adherences, all of them aimed at explaining the renovation process of the artifact as a change in the sense and the meaning, rather than the material. The considerations of this dissertation include, on the one hand, the relative nature of the term tenacity, a concept which defines the objects found and recognized in their suitability, that are capable of adapting and which finally require large doses of pragmatism for their reconfiguration, all these conditions being necessary but only sufficient a posteriori. On the other hand, the text reflects on the intangible shared among all the so-called objects, and which consists of the condition, perhaps extraordinary, of being recognized by the subsequent interveners of their history, convinced that their renovation represents an opportunity; their disappearance, a loss. Finally, the dissertation studies the concept of anachronism as a justification for the objects that prove to adapt to subsequent periods, and which fit in time in a complex manner.

Environmental change and hedonic cost functions for automobiles

This paper focuses on how changes in the economic and regulatory environment have affected production costs and product characteristics in the automobile industry. We estimate “hedonic cost functions” that relate product-level costs to their characteristics. Then we examine how this cost surface has changed over time and how these changes relate to changes in gas prices and in emission standard regulations. We also briefly consider the related questions of how changes in automobile characteristics, and in the rate of patenting, are related to regulations and gas prices.

Why fisheries collapse and what to do about it.

With the collapse of fisheries in many parts of the world causing widespread economic harm, attention is focused on a possible cause and remedy of fishery collapse. Economic theory for managing a renewable resource, such as a fishery, leads to an ecologically unstable equilibrium as difficult to maintain as balancing a marble on top of a dome. A fishery should be managed for ecological stability instead--in the analogy, as easy to maintain as keeping a marble near the base of a bowl. The goal of ecological stability is achieved if the target stock is above that producing maximum sustainable yield and harvested at less than the maximum sustainable yield. The cost of managing for ecological stability, termed "natural insurance," is low if the fishery is sufficiently productive. This cost is shown to pay for itself over the long term in a variable and uncertain environment. An ecologically stable target stock may be attained either with annually variable quotas following current practice or, preferably, through a market mechanism whereby fish are taxed at dockside if caught when the stock was below target and are untaxed otherwise. In this regulatory environment, the goal of maximizing short-term revenue coincides with the goal of ecological stability, thereby also maximizing long-term revenue. This new approach to fishery management is illustrated with the recently collapsed Newfoundland fishing industry. The Newfoundland cod fishery is expected to rebuild to an ecologically stable level in about 9 years and thereafter support an annual harvest of about 75% of the 1981-1990 average.

Asset-backed securities: The key to unlocking Europe's credit markets? Bruegel Policy Contribution 2014/07, 24 July 2014

The European market for asset-backed securities (ABS) has all but closed for business since the start of the economic and financial crisis. ABS (see Box 1) were in fact the first financial assets hit at the onset of the crisis in 2008. The subprime mortgage meltdown caused a deterioration in the quality of collateral in the ABS market in the United States, which in turn dried up overall liquidity because ABS AAA notes were popular collateral for inter-bank lending. The lack of demand for these products, together with the Great Recession in 2009, had a considerable negative impact on the European ABS market. The post-crisis regulatory environment has further undermined the market. The practice of slicing and dicing of loans into ABS packages was blamed for starting and spreading the crisis through the global financial system. Regulation in the post-crisis context has thus been relatively unfavourable to these types of instruments, with heightened capital requirements now necessary for the issuance of new ABS products. And yet policymakers have recently underlined the need to revitalise the ABS market as a tool to improve credit market conditions in the euro area and to enhance transmission of monetary policy. In particular, the European Central Bank and the Bank of England have jointly emphasised that: “a market for prudently designed ABS has the potential to improve the efficiency of resource allocation in the economy and to allow for better risk sharing... by transforming relatively illiquid assets into more liquid securities. These can then be sold to investors thereby allowing originators to obtain funding and, potentially, transfer part of the underlying risk, while investors in such securities can diversify their portfolios... . This can lead to lower costs of capital, higher economic growth and a broader distribution of risk” (ECB and Bank of England, 2014a). In addition, consideration has started to be given to the extent to which ABS products could become the target of explicit monetary policy operations, a line of action proposed by Claeys et al (2014). The ECB has officially announced the start of preparatory work related to possible outright purchases of selected ABS1. In this paper we discuss how a revamped market for corporate loans securitised via ABS products, and how use of ABS as a monetary policy instrument, can indeed play a role in revitalising Europe’s credit market. However, before using this instrument a number of issues should be addressed: First, the European ABS market has significantly contracted since the crisis. Hence it needs to be revamped through appropriate regulation if securitisation is to play a role in improving the efficiency of resource allocation in the economy. Second, even assuming that this market can expand again, the European ABS market is heterogeneous: lending criteria are different in different countries and banking institutions and the rating methodologies to assess the quality of the borrowers have to take these differences into account. One further element of differentiation is default law, which is specific to national jurisdictions in the euro area. Therefore, the pool of loans will not only be different in terms of the macro risks related to each country of origination (which is a ‘positive’ idiosyncratic risk, because it enables a portfolio manager to differentiate), but also in terms of the normative side, in case of default. The latter introduces uncertainties and inefficiencies in the ABS market that could create arbitrage opportunities. It is also unclear to what extent a direct purchase of these securities by the ECB might have an impact on the credit market. This will depend on, for example, the type of securities targeted in terms of the underlying assets that would be considered as eligible for inclusion (such as loans to small and medium-sized companies, car loans, leases, residential and commercial mortgages). The timing of a possible move by the ECB is also an issue; immediate action would take place in the context of relatively limited market volumes, while if the ECB waits, it might have access to a larger market, provided steps are taken in the next few months to revamp the market. We start by discussing the first of these issues – the size of the EU ABS market. We estimate how much this market could be worth if some specific measures are implemented. We then discuss the different options available to the ECB should they decide to intervene in the EU ABS market. We include a preliminary list of regulatory steps that could be taken to homogenise asset-backed securities in the euro area. We conclude with our recommended course of action.

European Integration and Europeanisation: Benefits and Disadvantages for Business. Bruges European Economic Policy (BEEP) Briefing 29/2013

European integration is a project of great economic importance for the 500 million consumers and 21 million companies in Europe. With the economic borders between Member States removed, Europeanisation becomes inevitable for companies. The paper proposes a framework to analyse the benefits and disadvantages for business that come with the process of European integration, structured according to the logic of the four fundamental freedoms of movement within the Internal Market (freedom of movement of goods, services, capital and people) complemented by the section on technology and innovation, and the general EU regulatory environment. Whereas the business decisions need to be taken on a case-by-case basis, taking into consideration firm’s own capabilities and resources as well as industry specificities, several recommendations for companies willing to Europeanise are made, based on an analysis of the regulatory macro-environment of the EU. Above all, any company willing to be successful in the EU has to become a learning organisation, responsive to the advancements of the macro-environment. The ability to anticipate the regulatory developments and to adjust one’s own business and corporate strategy accordingly is the key to achieving sustainable competitive advantage in the European Union.

Evolution of capital structure in East Asia - corporate inertia of endeavours?

The paper examines the capital structure adjustment dynamics of listed non-financial corporations in seven east Asian countries before, during and after the crisis of 1997–1998. Our methodology allows for speeds of adjustment to vary, not only among firms, but also over time, distinguishing between cases of sudden and smooth adjustment.Whereas, compared with firms in the least affected countries, average leverages were much higher, generalized method-ofmoments analysis of the Worldscope panel data suggests that average speeds of adjustment were lower in the worst affected countries. This holds also for the severely financially distressed firms in some worst affected countries, though the trend reversed in the post-crisis period. These findings have important implications for the regulatory environment as well as access to market finance.

Unions:rent creators or extractors?

This paper proposes a model of workplace-specific unions that integrates two views of what unions do. One view holds that unions mainly engage in rent extraction. Another view holds that unions mainly engage in rent creation by providing agency services that increase workplace productivity. We demonstrate that the choice between the two activities is systematically related to the economic and regulatory environment in which the union operates. Product market competition encourages rent creation, while labor market deregulation encourages rent extraction. Moreover, we provide a rationale for why firms may want to subsidize unions. © The editors of the Scandinavian Journal of Economics 2005.

An exploratory study of management accounting and control systems in a developing country

This thesis reports on the results of case studies in four commercial banks in Nigeria. The study focuses how management accounting and control systems (MCS) operate in the four banks. The study is motivated by the dearth of literature on management accounting practices in the developing world in general and in Nigeria in specific. The case study approach adopted in conducting the research was useful in exploring the dynamics of the MCS in the organisations. Data was gathered from two sources. First, semi-structured interviews were conducted with managers at the head office, regional office and branches of each bank. The participants were selected from different backgrounds and managerial levels to provide broader understanding of the operations of the MCS. Second, various internal and external documents were reviewed to provide supporting evidence for the interview results. New institutional sociology (NIS) provided the theoretical framework to understand the results. NIS provided explanations for how the MCS in the four banks were shaped by diverse external and internal factors. The key factors identified as shaping the operations of the MCS were the need to comply with the regulatory environment (coercive isomorphism), the need to maintain social and cultural support (normative isomorphism) and the need to imitate successful organisations in order to appear legitimate (mimetic isomorphism). The study also examines the interplay between the institutional forces, market forces and infra-organisational power relations. This analysis is necessary to overcome the criticism of NIS that it downplays the role of market forces, agency and intra-organisational relations. The findings of the study have implications for understanding the operations of MCS in the developing world.

The influence of political, economic and passenger market factors on international civil aviation

Civil aviation plays an essential role in maintaining international communications. Many extraneous factors influence the daily operations of the air transport industry. This thesis begins by investigating the major categories of so­ called "external interests" in civil aviation. These are shown to have played a significant part in ensuring the need for international agreement over the adoption of regulating principles. The combination and interaction of the various influences has produced a particular type of regulatory environment in which all commercial air services have to operate. The need for such regulation and the extreme difficulty experienced in trying to define universally acceptable methods of supervision is discussed. It is shown how opportunity for the development of on-scheduled air services was created by default on the part of the European Governments.The concept of so-called "scheduled" and "non-scheduled" sectors" is considered and it is suggested that growth of the inclusive tour industry resulted from inappropriate categorisation of the air services involved. The means by which development opportunities were created for inclusive tour operations is considered and the work then investigates the importance of British air transport policy in their exploitation. The politics of British civil aviation in the post-war years is the subject of detailed examination and the process by which Independent airlines were encouraged to develop inclusive tours, is identified. This theme is expanded to demonstrate the vital contribution of British air transport policy in the restructuring of the international industry. The subsequent involvement of the United States is shown to have been directed specifically towards the satisfaction of domestic issues. British objectives, however, are considered to have been more generally concerned with improving the tariff structure. The unique opportunities for British experimentation with international fares are seen to have major influence in forcing the pace of tariff rationalisation.

Adjusting to institutional realities: the 2006 NGO law and its effects on civil society in Russia

Key findings: The paper investigates the impact that the legislative changes of 2006 had on civil society in Russia. This legislation has change the regulatory environment in which civil society actors such as Third Sector Organisations operate. Using the past development of civil society organisations as well as insights about how the institutional environment influences this article illustrates: - the undemocratic nature and motivation of the law and how it exploits the structural weaknesses of civil society - how Third Sector Organisations rationalise and translate the legislative changes into their organisational realities and how this changed or did not change their behaviour - the shift in state-civil society relations away from liberal co-existence into more hierarchical arrangements were Third Sector Organisations are subordinated to the state. These trends have far reaching implications for civil society. The empirical evidence shows that state now manages civil society to meet its own political ends. It also shows that organisations in the field welcome the more engage and directive nature of the Russian state. Why is this important? What does it mean for business or other users? Are there policy implications? The research is important as it shows how Third Sector Organisations have reacted to the legislative changes. Further it provides a basis for interpretation of the potential future development of civil society. Additional it highlights how the continuous process of democratisation in transition economies sometimes might come unstuck. In particular donor agencies will need to consider these trends when disturbing funding to Third Sector Organisations.

Electronic commerce adoption:a study of business-to-business practice in Saudi Arabia

Electronic commerce (e-commerce) has become an increasingly important initiative among organisations. The factors affecting adoption decisions have been well-documented, but there is a paucity of empirical studies that examine the adoption of e-commerce in developing economies in the Arab world. The aim of this study is to provide insights into the salient e-commerce adoption issues by focusing on Saudi Arabian businesses. Based on the Technology-Organisational-Environmental framework, an integrated research model was developed that explains the relative influence of 19 known determinants. A measurement scale was developed from prior empirical studies and revised based on feedback from the pilot study. Non-interactive adoption, interactive adoption and stabilisation of e-commerce adoption were empirically investigated using survey data collected from Saudi manufacturing and service companies. Multiple discriminant function analysis (MDFA) was used to analyse the data and research hypotheses. The analysis demonstrates that (1) regarding the non-interactive adoption of e-commerce, IT readiness, management team support, learning orientation, strategic orientation, pressure from business partner, regulatory and legal environment, technology consultants‘ participation and economic downturn are the most important factors, (2) when e-commerce interactive adoption is investigated, IT readiness, management team support, regulatory environment and technology consultants‘ participation emerge as the strongest drivers, (3) pressure from customers may not have much effect on the non-interactive adoption of e-commerce by companies, but does significantly influence the stabilisation of e-commerce use by firms, and (4) Saudi Arabia has a strong ICT infrastructure for supporting e-commerce practices. Taken together, these findings on the multi-dimensionality of e-commerce adoption show that non-interactive adoption, interactive adoption and stabilisation of e-commerce are not only different measures of e-commerce adoption, but also have different determinants. Findings from this study may be valuable for both policy and practice as it can offer a substantial understanding of the factors that enhance the widespread use of B2B e-commerce. Also, the integrated model provides a more comprehensive explanation of e-commerce adoption in organisations and could serve as a foundation for future research on information systems.

Determinants of B2B e-commerce adoption in Saudi Arabian firms

Business-to-business (B2B) electronic commerce (e-commerce) has become an increasingly important initiative among organisations. The factors affecting the adoption decisions have been well-documented but there is a paucity of empirical studies that examine the adoption of e-commerce in developing economies in the Arab world. The aim of our study is to provide insights into the salient e-commerce adoption issues by focusing on Saudi Arabian businesses. We developed a conceptual model for B2B e-commerce adoption incorporating six factors. Survey data from 450 businesses were used to test the model and hypotheses. The analysis demonstrates that, (1) when e-commerce preliminary adoption is investigated, organizational IT readiness, management support and regulatory environment emerge as the strongest factor, (2) pressure from customers may not have much effect on the preliminary adoption of e-commerce by companies, but does significantly influence on the utilisation of e-commerce by firms, and (3) Saudi Arabia has a strong ICT infrastructure for supporting e-commerce practices. Taken together, these findings on the multi-dimensionality of e-commerce adoption show that preliminary adoption and utilisation of ecommerce are not only different measures of ecommerce adoption, but also have different determinants. The implications of the findings are discussed and suggestions for future inquiry are presented.
