Abstract Eco-tourism gives consideration to both ecological conservation and recreation, aiming to protect resources by means of making tourists recognizing the importance of ecosystem."Houbihu Marine Conservation Area "in the National Kenting Park is established for the conservation of biological diversity from protecting sea urchins in 2003 to all marine organisms two years later. Recovery of marine resources encouraged the idea to develop eco-tourism in the area; not only to propagate the benefits from resources conservation by allowing tourists for near contacts to marine ecosystem and sharing the achievements of protection, but also to promote transformation of local fishers and to improve their economic conditions. This study explores the feasibility of this idea, by literature reviews, questionnaire survey and in-depth interview with the six groups of people: tourists, managers, enforcement officials, experts (including scholars), industries and non-government organization. Discussions on the results and recommendations were provided in the study. ¡ikeyword ¡jEco-tourism¡BBiologicaldiversity¡BHoubihuMarine¡Bliterature reviews¡Bquestionnaire survey¡Bin-depth interview

We present a novel marketing method for consumer trend detection from online user generated content, which is motivated by the gap identified in the market research literature. The existing approaches for trend analysis generally base on rating of trends by industry experts through survey questionnaires, interviews, or similar. These methods proved to be inherently costly and often suffer from bias. Our approach is based on the use of information extraction techniques for identification of trends in large aggregations of social media data. It is cost-effective method that reduces the possibility of errors associated with the design of the sample and the research instrument. The effectiveness of the approach is demonstrated in the experiment performed on restaurant review data. The accuracy of the results is at the level of current approaches for both, information extraction and market research.

Consumer-generated reviews play an important role in online purchase decisions for many consumers. However, the quality and helpfulness of online reviews varies significantly. In addition, the helpfulness of different consumer-generated reviews is not disclosed to consumers unless they carefully analyze the overwhelming number of available contents. Therefore, it is of vital importance to develop predictive models that can evaluate online product reviews efficiently and then display the most useful reviews to consumers, in order to assist them in making purchase decisions. This thesis examines the problem of building computational models for predicting whether a consumer-generated review is helpful based on consumers' online votes on other reviews (where a consumer's vote on a review is either HELPFUL or UNHELPFUL), with the aim of suggesting the most suitable products and vendors to consumers.In particular, we propose in this thesis three different helpfulness prediction approaches for consumer-generated reviews. Our entropy-based approach is relatively simple and suitable for applications requiring simple recommendation engine with fully-voted reviews. However, our entropy-based approach, as well as the existing approaches, lack a general framework and are all limited to utilizing fully-voted reviews. We therefore present a probabilistic helpfulness prediction framework to overcome these limitations. To demonstrate the versatility and flexibility of this framework, we propose an EM-based model and a logistic regression-based model. We show that the EM-based model can utilize reviews voted by a very small number of voters as the training set, and the logistic regression-based model is suitable for real-time helpfulness predicting of consumer-generated reviews. To our best knowledge, this is the first framework for modeling review helpfulness and measuring the goodness of models. Although this thesis primarily considers the problem of review helpfulness prediction, the presented probabilistic methodologies are, in general, applicable for developing recommender systems that make recommendation based on other forms of user-generated contents.

The discussion about high culture and popular culture in our society has been going on for decades. In few places is it as loud as within culture journalism and the critics’ society, where the question of what is good taste and what is dumb entertainment constantly gets brought to the surface. Film is a particularly vulnerable area, since it is such a universally appealing and rather young medium. In America and England several studies have been performed of the reviewing society and reveiwers’ use of high and low art-discourse in their writing. The Swedish market is sorely lacking in this area.   This study is an attempt to shed some light on the way Swedish culture journalism works, with the focus being Swedish film reviews. The goal is to explore the use of high culture and popular culture discourse within Swedish reviews by examining the movie reviews published in the two large Swedish newspapers Dagens Nyheter and Aftonbladet in 2013. The reviews were studied using a number of variables, some of which represented the high culture discourse, and some of which represented the popular culture discourse. The study showed that the reviewers of these newspapers tended to use both high art discourse and popular culture discourse within their reviews to almost the same extent. The news papers were also very similar in the way they used the variables for high culture and popular culture discourse.

<b>Background:</b> The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach offers a transparent framework for rating the certainty of evidence in systematic reviews. Concerns, however, have been raised that use of GRADE beyond biomedical interventions frequently downgrades the 'best evidence possible' for many complex interventions. This DPhil thesis aims to (1) further investigate the challenges of using GRADE in systematic reviews of complex interventions, (2) explore how the GRADE approach can be advanced to address these challenges, and (3) inform the write-up and dissemination of a new GRADE guidance for complex interventions. <b>Methods:</b> To address the broad aims of this thesis a range of methodological approaches were employed, primarily drawing on the best-practice techniques for developing research reporting guidelines (see Chapter 2). First, a systematic literature review method was used to establish whether an adequate system already exists for rating the certainty of evidence for complex interventions and informing the need for a new guidance (Chapter 3). Further consultation with experts, including semi-structured interviews with review authors and GRADE methodologists, provided a nuanced understanding of the challenges of applying GRADE in reviews of complex interventions and suggestions for advancing the guidance on GRADE (Chapter 4). Agreement around these suggestions was explored in a Delphi-based online expert panel (Chapter 5), and the content of the new GRADE guidance for complex interventions was discussed indepth in a three-day expert meeting held in Oxford in May 2017 (Chapter 6). <b>Results:</b> The systematic literature review identified a few systems attempting to modify GRADE for public health interventions; however, there was little reporting of rigorous procedures in the development and dissemination of these systems. Qualitative interviews captured differences in views on GRADE use between review authors and GRADE methodologists. Specifically, GRADE methodologists found it critical to consider GRADE from the beginning of the review process and exercise judgment in GRADE ratings. Review authors, on the other hand, often thought of GRADE as an 'annoying add-on' at the end of the review process and felt challenged by the need to be more interpretative with evidence and sift through many publications on GRADE. Suggestions were made to enhance the GRADE guidance. No significant disagreement was found in the online expert panel on any domain of evidence, and the expert meeting provided further insights into the content of the new GRADE guidance for complex interventions. Participants agreed that the new guidance should specify the meaning of the construct of 'certainty of evidence' for complex interventions, consider revisions of the initial categorisation of evidence based on study design, and better assess the coherence of the causal pathway of complex interventions. <b>Conclusion:</b> This thesis work consolidates up-to-date methodological knowledge on reviewing complex interventions by providing critical examination of the existing approaches and new insights. In transparent reporting of the research phases, it informs development of a new GRADE guidance on rating the certainty of evidence in systematic reviews of complex interventions.

Magister Curationis - MCur / Pregnancy induced hypertension is one of the causes of maternal, fetus and neonatal morbidity and mortality. It is the condition in which a pregnant woman develops hypertension because of physiological changes that result during pregnancy and both mother and fetus can be affected. According to the World Health Organization (WHO), the first target of the third United Nations Sustainable Development Goals (SDG-3) is to reduce the maternal mortality rate (MMR) to less than 10 per 100.000 live births by 2030 (WHO, 2017). This is because globally, about 350 000 women die every year from pregnancy related causes (Hogan, Foreman, & Naghavi, 2010). According to the WHO (2015), these conditions namely post-partum hemorrhage, hypertension in pregnancy, infections, unsafe abortion and other delivery-related complications cause three quarters of all maternal deaths in the World. Hence the needs to prevent or successfully treat conditions that contribute to this scourge (WHO, 2011). The two main interventions that are used to prevent or treat hypertension in pregnancy are medication and lifestyle adjustment. However, it is important to understand the intervention that is most suited to a context and its patient and compare the effects of these interventions on management of hypertension in pregnant women as a patient outcome.

The aim of my diploma thesis was to evaluate four densities of growth by chosen varieties of potatoes. The thesis deals with the experiment on 4 different varieties of potatoes. I have chosen the standard technology of growing ware potatoes. The selected densities of growth were 35 000, 40 000, 45 000 and 50 000 young plants ha-1. Each variant was repeated four times. I have evaluated the yield of bulbs, the share and yield of ware bulbs, the average number of bulbs for one plant, the weight of bulbs for one plant, the average weight of a bulb and the average weight of ware bulbs. The research was done on a private farm like the field experiment. The farm is located in potato-growing area in Vysočina Region, 490 metres above the sea level. Potatoes are grown approximately over 7 hectares on the farm. The experiment started in 2010. The potato planter MARS 42 was used for the planting. The distance between drills was 0,75 metre. Parcels consisted of 4 drills, each drill equals one repetition, each parcel equals one density of growth. On purchase of samples was realized the kickoff of 10 plants from each repetition. What followed was division of bulbs according to their size in each sample. They were divided into bulbs smaller than 40 millimetres and bigger. After that the samples were weighed and bulbs were counted. The number of bulbs and the weight of bulbs are very important for subtotal. It was established the variety Mirage made the best results when the density was 45 000 plants ha-1. The variety Agria had two suitable densities of growth, namely 40 000 and 45 000 plants ha-1. There was no considerable difference between them. In contrast with previous, the varieties Victoria and Marabel made the best result when the density was 35 000 plants ha-1. I have realized the density 50 000 plants ha-1 is explicitly unsuitable for all varieties. This density of growth is loss-making especially because of lowering of all assessed indexes. Another disadvantage is higher costs (more bulbs are required) and then there is also bigger risk of diseases and pests.

Implementation strategies for the use of clinical practice guidelines are an integral component in bridging the gap between the best research evidence and clinical practice. However, despite some remarkable investments in health research regarding clinical practice guidelines implementation strategies, it is not yet known which of these are the most effective for intensive care units. The purpose of this research study was to systematically identify and /or search, appraise, extract and synthesize the best available evidence for clinical practice guidelines implementation strategies in intensive care units, in order to develop a draft guideline for clinical practice guidelines implementation strategies in the intensive care units. A systematic review design was used to systematically identify and /or search, appraise, extract and synthesize the best available evidence from the eligible included Level 2 studies (randomized controlled trials and quasi-experimental studies). Level 2 studies were applicable because they present robust evidence in the research results regarding effectiveness of clinical practice guideline implementation strategies. Furthermore, although other systematic reviews conducted in this area before, they included studies of In addition, no systematic review was identified that reviewed Level 2 studies and developed a guideline for clinical practice guideline implementation strategies in the intensive care units. Hence, including only Level 2 studies was distinctive to this research study. Databases searched included: CINAHL with full text, Google Scholar, Academic search complete, Cochrane Register for Randomized Controlled Trials Issue 8 of 12, August 2013, and MEDLINE via PUBMED. Hand search in bound journals was also done. The search strategy identified 315 potentially relevant studies. After the process of critical appraisal, thirteen Level 2 studies were identified as relevant for the review. Of the 13 relevant studies, 10 were randomized controlled trials and three were quasi experimental studies. After the critical appraisal ten RCTs were included in the systematic review. Three studies (quasi-experimental) were excluded on the basis of methodological quality after the critical appraisal and agreement by the two independent reviewers. The Joanna Briggs Institute Critical Appraisal MASTARI Instrument for Randomized Controlled trials/ Experimental studies, and The Joanna Briggs Institute data extraction tools were used to critically appraise, and extract data from the ten included randomized controlled trials. The two reviewers who performed the critical appraisal were qualified critical care professional nurses and experts in research methodology. These reviewers conducted the critical appraisal independently to ensure the objectivity of the process. Appropriate ethical considerations were maintained throughout the process of the research study. The results indicated that 80 percent of the included studies were conducted in adult intensive care units while 20 percent were conducted in the neonatal intensive care units. Furthermore, 60 percent of the studies were conducted in the United States of America, 10 percent in France, a further 10 percent in Taiwan, another 10 percent in England and yet another 10 percfent was conducted in Australia and Newzealand. The included studies utilized more than one (multifaceted) implementation strategies to implement clinical practice guidelines in the intensive care units. The first most utilized were: printed educational materials; Information/ educational sessions/meetings; audit and feedback and champion/local opinion leaders; seconded by educational outreach visits; and computer or internet usage. Third most used were active/passive reminders; systems support; academic detailing/ one-on-one sessions teleconferences/videoconferences and workshops/in services. Fourth most used were ollaboration/interdisciplinary teams; slide shows, teleconferences/videoconferences and discussions. Fifth most used were practical training; monitoring visits and grand rounds. However all the strategies were of equal importance. Conclusively, the included studies utilized multifaceted implementation strategies. However, no study indicated the use of a guideline for the implementation strategies in the process of clinical practice guidelines implementation. The systematic review developed a draft guideline for clinical practice guideline implementation strategies in the intensive care units. The guideline will enhance effective implementation of clinical practice guidelines in such a complex environment.

The Performance Management System (PMS) has been introduced in the Republic of South African public service with intentions of planning, monitoring, developing under-performance, rating and rewarding good performance. The study was undertaken as an attempt to investigate the impact of the PMS on employees of the ECPL. The literature review shows that there are challenges facing the institution with regards to implementation of PMS. The findings of the study indicated that the supervisors have no understanding of PMS instead they used it as punishing tool. Other findings of the study showed that there’s a culture within the institution of using PMS as a money making scheme or a 14th checque. To achieve this, a semi- structured questionnaire was issued to employees of the ECPL. The recommendation on the basis of the study is that the compliance issue should be strengthened and disciplinary measures be taken against employees who failed to comply with the provisions of the PMS policy.
