Non-commercial invertebrate discards in an experimental trammel net fishery

Non-commercial invertebrate discards in an experimental trammel net fishery were studied in relation to selectivity of the gear, depth, soak time and season. Forty experimental fishing trials were carried out over a 1-year period with six combinations of small mesh (100, 120 and 140 mm) inner and large mesh (600 and 800 mm) outer panels. On average, 43.8 +/- 12.2 (SD) (individuals 1000 m(-1) of net) of non-commercial invertebrates were discarded, accounting for 48% and 65% of the total catch and total discards by numbers, respectively. Within non-commercial invertebrates discards, the six most abundant species by number were Phallusia mammillata (Cuvier) (27.5%), Cymbium olla (L.) (13.0%), Sphaerechinus granularis (Lamarck) (11.3%), Paracentrotus lividus (Lamarck) (10.9%), Astropartus mediterraneus (Risso) (8.2%) and Astropecten aranciacus (L.) (8.1%); Echinoderms (43.1%) particularly important. The highest and lowest discard ratios were found in autumn and winter, respectively. Discards generally decreased with depth, varied considerably in relation to soak time and were not related to mesh size combinations. Trammel nets seem to be the most important gear in terms of ecological impacts on benthic invertebrates compared with other coastal fishing gears and at the depths studied (15-60 m).

Using creative problem solving (CPS) to improve leadership in a non-profit organization

The purpose of this study was to evaluate the effectiveness of the Creative Problem Solving (CPS) method in improving the leadership process in a non-profit organization. The research was designed around an intervention and structured in three stages (pre-consult, intervention and follow-up), with a team designated by management, in order to bring leadership cohesion to both departments of the organization and also between the board and executive management. The results, expressed in the tasks performed and in the interviews to team members, allowed us to conclude on the effectiveness of the CPS method to improve organizational leadership, by establishing a stronger relationship between departments, as well as, in the long term, between the board and executive management. These results highlight possible solutions to improve the leadership of non-profit organizations.

Tourism in Timor Leste: contributions to a sustainable development

The main goal of this thesis is to analyse tourism as a contributor to sustainable development, from a supply and demand perspective, in Timor-Leste, a destination not only “young” but also framed in an early stage of touristic development. From the supply side, studies 1 and 2 present a literature review on the concept of sustainable development, in small islands destinations, its weaknesses and vulnerabilities, and whose attractiveness lies in an integrated set of natural resources (attractive beaches, biodiversity, the coral triangle, a rich fauna and flora), its geographic location, tropical climate, socio cultural tradition and a Luso-Timorense cultural mix, that can meet the needs of important segments of the tourist demand. In these studies, the focus is on the residents’ attitudes in relation to sustainable development and, in particular, on the perceptions of local leaders about the importance of the operationalization of the concept. As Timor-Leste is a “young” destination, it is travel industry is still faced with several problems in order to be able to satisfy the demand and to meet the tourists’ motivations, preferences and requirements. In this perspective, the study 3 examines diaspora tourism, while a niche market, allowing for not only the entry of Timor-Leste in the international tourism market, but also an articulation between the people of Timor-Leste in the diasporas and the development of sustainable tourism . In general, the results show that the development of sustainable tourism cannot be successfully implemented without the involvement of all stakeholders such as residents, public sector (local government, policy makers, planners), private sector (tourism operators), and non-governmental organizations (NGOs) that include civil society, religious institutions, the academic community (the supply side), and Timorese diasporas tourists as consumers (the demand side).
