Coastal erosion project, Diani beach, Kenya
No full textMaster project report. Since the seventies, the establishment of hotels and other facilities has increased the pressure on the Kenyan coast. During the last decade, hotel managers and residents in Diani Beach have been experiencing problems with erosion. The only measures taken to address the problem are individually built seawalls to protect private properties. These seawalls are mostly not properly built and do not decrease the erosion rate. Erosion continues and beaches are still disappearing. In some places, coral rock is exposed or buildings collapse. The economy in Diani Beach is strongly depending on tourism. A white beach with a gentle slope and a flourishing ecosystem of lagoon and coral reef is desirable to attract tourists. The current situation in most parts of Diani Beach is far from desired. Diani Beach seems to be subject to structural erosion, due to several reasons. Initially, the narrowness of the African continental shelf leads to an easily loss of sediment into the deep ocean. Also the fact that there are no high mountain ranges along the Kenyan coast results in a low rate of sediment flowing into the ocean. A lack of sand combined with the relative stableness of the African crustal plate can be seen as causes for structural erosion. In Diani Beach the process is accelerated by a number of factors, both human and nature induced. Measures have to be taken to recover and maintain the desired situation. However, it is difficult to determine the optimal solution because of policy issues and lack of data. Several measures are proposed, which can be divided into three categories: management and policy measures, soft measures and hard measures. The first category implies e.g. determination of the setback line, altered approach to fishery and enforcement of legislations. Soft measures include planting of vegetation and beach nourishment. Breakwaters, groynes and improvement of seawalls are hard measures. A combination of measures can have effect on both short and long term, first recovering and subsequently maintaining the desired situation. However, more data have to be gathered to determine the best combination of measures, make a proper design and find the way to implement them.Hydraulic EngineeringCivil Engineering and Geoscience
Text reflexivity in academic writing: a cross-disciplinary and cross-generic analysis
No full textThe article explores reflexive phraseology across academic genres and disciplines. Employing a corpus-based approach, the study focuses on how metatextual phraseological units vary across academic research articles and book review articles and academic disciplines (business and economics). The study shows that phraseological units can be very helpful signals for the analysis of generic and argumentative structure of academic writing. The findings also demonstrate that convergences and divergences between closely related disciplines and genres help to differentiate different forms of disciplinary discourse
Introduction [Variation and Change in Spoken and Written Discourse]
No full textThe book focuses on aspects of variation and change in language use in spoken and written discourse on the basis of corpus analyses, providing new descriptive insights, and new methods of utilising small specialized corpora for the description of language variation and change. The sixteen contributions included in this volume represent a variety of diverse views and approaches, but all share the common goal of throwing light on a crucial dimension of discourse: the dialogic interactivity between the spoken and written. Their foci range from papers addressing general issues related to corpus analysis of spoken dialogue to papers focusing on specific cases employing a variety of analytical tools, including qualitative and quantitative analysis of small and large corpora. The volume constitutes a highly valuable tool for applied linguists and discourse analysts as well as for students, instructors and language teachers
