Lễ Cúng Cá Ông : the Beliefs and Traditional Worship of the Fishermen in Central Việt Nam / Lễ Cúng Cá Ông : la croyance en adoration traditionnelle des pêcheurs au Viét Nam central

Lantz, Sandra January 2007 (has links)
The purpose of this project, as a minor field study, is to study the fishermen and their beliefs and worship in Việt Nam. Since the worship of the fishermen exists all along the coast from the Gulf of Thailand in the south to Ha Long Bay and beyond in the north, the study is concentrated to the coastal area of central Việt Nam – that is in the Quảng Nam surroundings, mainly Hội An but also Đà Nẵng. The aspects of the representation of the worship in society as well as how it is looked upon by society, both religiously (according to tôn giáo) and politically, will also be dealt with. This study is based upon observation and non-structured interviews. Although partially being based upon Grounded theory, the study is theoretically inspired by Graham Harvey’s book Animism. Respecting the Living World. The outcome shows that the Cá Ông worship is based upon historical events and experiences. The worship, which is carried out among all fishermen, is similar throughout the coast though the dates of worship may vary. Politically the religion is not necessarily threatened, although the 1992 Constitution is somewhat ambiguous. In society, the religion is respected, but peasants do not intermingle in festival activities concerning the fishermen’s traditions. There are links to be found dealing with the arguments of Harvey when it comes to animist beliefs and features of Cá Ông. / Le but de cette étude de champ c’est d’étudier les pêcheurs de Viét Nam et leur confianceen et leur affection à Cá Ông. Puisque la confiance des pêcheurs dit-on existe le long du chemin du sud , de la baie de Thailand, à Ha Long Bay au nord, l’étude a été concentrée à la côte du Viét Nam central surtout la province de Quang Nam, concentrée à Hôi An et aussi Dà Nang. Comment la croyance des pêcheurs est representée dans la société et comment la société regarde la pratique vont être traité d’un perspectif politique et religieux. L’étude s’est basée sur l’observation participante sur des interviews semistructurelles. Partiellement la théorie est liée à l’Animisme respectant le monde vivant de Graham Harvey basé sur Grounded Theory. Le résumé montre que la croyance en Cà Ông est basée sur des événementset des experiences historiques. La prière pratiquée par tous les pêcheurs est faite à la même facon même si les dates pour les festivaux et les ceremonies diffèrent. Politiquement la croyance est respectée et en partie reconnue, mais les paysans n’assistent pas aux festivals concernant des traditions des pêcheurs. Il y a des parallèles entre l’opinion d’Harvey sur l’Animisme et les parties animistes trouvées dans la croyance en Cá Ông. / Nội dung của bài học tự do này là học và nguyên cứu về những người ngư dân ở việt nam về sự tín ngưỡng và tôn thờ của họ đối với Cá Ông (Whale). Theo những tin đồn của những người ngư dân đã cho thấy Cá Ông tồn tại dài theo biển của ThaiLan và xuống dưới phía nam của vịnh Hạ Long và sau đó tiếp tục lên phía bắc và ở đây bài luận này chỉ chú trọng nhất đến những ngư dân của vùng biển trung tâm Việt Nam tức là tỉnh Quảng nam, trong đó có Đà nẵng và chú trọng nhất là ở Hội An. Những gì tin, mê tín và tín ngưỡng của ngư dân là điển quan trọng được diễn biến thực tế trong xã hội đời sống ngay nay, và những gì xã hội thấy được sự thử thách sẽ diễn ra cả hai bên, như tôn giáo và cũng như trong lĩnh vực chính trị. Trong bài luận này cơ bản là gặp gở sinh viên đã trực tiếp quan sát và học hỏi những tư liệu cũng như những cuộc thẩm vấn thực tế. Lý thuyết của bài học này là một phần có liên quan đến Grahamn Harvey’s Animism. (Thuyết duy linh đối với duy vật) Respecting the Living World (Tôn trọng thế giới của sinh vật sống). Phần kết luận cho chúng ta thấy rằng sự tồn tại của Cá Ông là căn bản của những câu chuyện đã xảy ra va kinh nghiệm của ngư dân. Lễ cúng cá ông, được ngư dân thường tổ chức ở vùng biển và diễn ra hàng năm như thường lệ, nhưng ngày va mùa cúng thì có vùng lại khác nhau. Trong lĩnh vực chính trị cho thấy, sư tín ngưỡng của của ngư dân đã được tôn trọng và một phần được ông chứng trong xã hội, nhưng không phải ai cũng thờ cúng cá ông ví dụ, những người làm nghề nông thì khác chẳng hạn, họ không cúng Cá Ông như ngư dân làm biển. Ngược lại Lễ cúng cá ông đã trở thành một phong tục truyền thống của riêng ngư dân. Quan điểm của Harvey’s về thuyết duy linh đối với duy vật nó song song với nhưng linh thiêng vể, thần linh mà con người đối với Cá Ông. / Uppsatsen har senare publicerats i modifierad form som boken: "Lantz, Sandra (2009).

Structure and dynamics of the Gulf of Maine humpback whale population

Robbins, J. January 2007 (has links)
Population structure and vital rates of Gulf of Maine (GOM) humpback whales, Megaptera novaeangliae, were studied by a combination of longitudinal data, region-wide surveys and modern mark-recapture statistical methods. Demography and rates of exchange were examined among six GOM areas. Juveniles and females were preferentially encountered in southern GOM habitats, including at the Studds Stellwagen Bank National Marine Sanctuary (SBNMS). Multi-state modelling also revealed unequal probabilities of movement between areas that was not explained by inter-area distance, adjacency, whale density or dominant prey type. Aerial surveys and photo-identification data indicated that the population was likely closed to migration between June and September. Otherwise, seasonal trends in population composition were consistent the demographically staggered migration reported in other oceans. Over-wintering occurred,but there was little evidence that a significant number of humpback whales failed to undertake or complete migration each year. Vital rates varied with sex, age and time. Juveniles exhibited lower and more variable survival than adults and so were a potential source of downward bias in “non-calf” survival estimates. Males exhibited higher survival than females and achieved maximal survival at age five, the estimated age at male puberty. By contrast, females did not reach peak survival until the current average age at first birth (8.78 years, s = 2.33). The latter was significantly higher than previous estimates and females that recruited by age seven had a lower likelihood of subsequent survival than those that recruited late. Costs of reproduction persisted into adulthood, with breeders exhibiting lower survival than nonbreeders. Calves born during years of low fecundity exhibited lower survival than those born when fecundity was high, possibly due to lower maternal investment. Costs of reproduction have not previously been described in cetaceans, but are consistent with the risks potentially associated with capital breeding.

Behavioural ecology of fishermen and odontocetes in a depredation context / Écologie comportementale des pêcheurs et odontocètes dans un contexte de déprédation

Richard, Gaëtan 23 November 2018 (has links)
De nombreux prédateurs marins se nourrissent directement des prises des pêcheurs. Ces interactions, définies comme de la déprédation, engendrent des conséquences socio-économiques considérables pour les pêcheurs ainsi que des implications de conservation pour la faune sauvage. D’un côté, la déprédation endommage le matériel et augmente l’effort de pêche pour atteindre les quotas. D’un autre côté, la déprédation augmente le risque de mortalité des prédateurs marins (prise accidentelle ou rétorsion létale par les pécheurs). La pêcherie à la palangre est la plus impactée par la déprédation, principalement par les odontocètes, ce qui incite à trouver des solutions. La majorité des études se concentrant sur la déprédation s’est principalement basée sur des observations en surface, de ce fait la manière dont les prédateurs retirent les poissons sur les lignes reste confuse. Par ailleurs, l’impact de la déprédation sur le comportement des pêcheurs ainsi que les facteurs expliquant leur détectabilité n’ont reçu que peu d’intérêt. L’objectif de cette thèse est donc d’étudier ces problématiques par un suivi acoustique, une utilisation de balises et une approche en écologie comportementale humaine, en se concentrant sur la pêcherie palangrière française ciblant la légine australe (Dissostichus eleginoides) impactée par la déprédation des orques (Orcinus orca) et des cachalots (Physeter macrocephalus). Les capitaines ont été décrits comme recherchant leur ressource selon la théorie de « l’optimal foraging », mais avec des perceptions de la compétition et du succès de pêche qui divergent. Certains capitaines seraient ainsi plus enclins à remonter les palangres au plus proche et à rester sur une zone, même en présence de compétition, augmentant alors le risque d’interaction. L’acoustique des navires a révélé que certaines manoeuvres (marche arrière par exemple) propagent différemment sous l’eau. La manière dont les capitaines manoeuvrent leur palangrier influencerait ainsi leur détectabilité et donc leur risque d’interaction avec les prédateurs. D’autre part, l’utilisation de capteurs sur les palangres et les animaux a révélé que les orques et les cachalots sont capables de déprédater sur les palangres posées sur le fond marin. Ces observations laissent à penser que les odontocètes sont en mesure de localiser l’activité de pêche bien avant la remontée de la ligne, ce qui pourrait être expliqué par une signature acoustique spécifique du déploiement de la ligne. L’ensemble des résultats de cette thèse suggère que la déprédation sur les palangres démersales est très probablement sous-estimée. Cette thèse apporte également des éléments importants pour la lutte contre la déprédation, en montrant la nécessité de protéger les palangres dans l’intégralité du processus de pêche. / Many marine predator species feed on fish caught by fishers directly from the fishing gear. Known as depredation this interaction issue has substantial socio-economic consequences for fishermen and conservation implications for the wildlife. Costs for fishers include damages to the fishing gear and increased fishing effort to complete quotas. For marine predators, depredation increases risks of mortality (lethal retaliation from fishers or bycatch on the gear). Longline fisheries are the most impacted worldwide, primarily by odontocetes (toothed whales) depredation, urging the need for mitigation solutions to be developed. Most of studies assessing depredation have primarily relied on surface observation data, thus the way odontocetes interact with longlines underwater remains unclear. Besides, the way fishermen respond to depredation during fishing operations, or can influence their detectability to odontocetes, have been poorly investigated. This thesis therefore aimed at investigating these aspects through a passive acoustic monitoring, bio-logging and human ecology approaches, focusing on the French Patagonian toothfish (Dissostichus eleginoides) longline fisheries impacted by killer whales (Orcinus orca) and sperm whales (Physeter macrocephalus). Firstly, this thesis reveals that captains behave as optimal foragers but with different personal perception of competition and fishing fulfilment. Some captains would thus be more likely to stay within a patch or to haul closest longline even in presence of competition, suggesting these captains would show higher interaction rates. Additionally, the propagation of vessels’ acoustics varied depending on the type of manoeuvre (e.g. going backward vs. forward). The way captains use their vessels to navigate may therefore influence their detectability and so their depredation level. Secondly, loggers deployed on both the longlines (accelerometers) and odontocetes (GPS-TDR) revealed that killer whales and sperm whales are able to depredate on longlines while soaking on the seafloor. These observations suggest, therefore, that odontocetes can localise fishing activity before the hauling, which could be partially explained by specific acoustic signatures recorded during the setting process. Altogether, the results of the thesis suggest that depredation rates on demersal longlines are most likely underestimated. The thesis also brings some important insights for mitigation measures, suggesting that countermeasures should start from setting to hauling.

ON THE DYNAMICS OF SOCIAL RELATIONSHIPS AND VOCAL COMMUNICATION BETWEEN INDIVIDUALS AND SOCIAL UNITS OF SPERM WHALES

Gero, Shane 06 December 2012 (has links)
Within-population behavioural variation can greatly affect the ecology of a species and the outcome of evolutionary processes. This study aimed to determine how variable sperm whale social and vocal behaviour is between both individuals and their social units. The population of whales off Dominica is small and isolated from communities in neighbouring waters. Female and immature whales live together in social units containing about 7 animals. I analysed their social relationships and their ‘coda’ communication signals using an unparalleled dataset of social and vocal interactions at the level of the individual. Within units, calves were significant nodes in their social unit’s network, and thus I provide quantitative support for the hypothesis that communal calf care acts as the primary evolutionary driver for group formation in this species. Social relationships within and between units were diverse, while the spatial spread of individuals within units and their travel speeds were similar among all of the units. I identified long-term patterns of association between units consistent over decadal time scales. Social units had characteristic vocal repertoires, but all were dominated by the ‘1+1+3’ and ‘5R’ coda types. Differences between units resulted from some units using specific 4-click coda types. Units and individuals used different accents on their ‘5R’ codas, but the ‘1+1+3’ coda was stereotyped across all individuals and units studied. The repertoires of different units were as similar as units within vocal clans in the Pacific. My results support the hypothesis that the ‘5R’ coda may function in individual identification. The stability of the ‘1+1+3’ coda may be the result of selection for a marker of clan membership. Individual repertoires differed consistently across years; and contrary to an existing hypothesis, new mothers did not vary their repertoire to be more distinct after giving birth. However, calves did use a class-specific ‘3+1’ coda. In summary, sperm whale social and vocal behaviour vary between individuals and among units. Variation in the social and vocal behaviour of female sperm whales results from a trade-off between individuality and conformity within units and clans.

"It's alive!" : Hur Frankensteinberättelsen förändrats från Mary Shelleys originaltext till Mary Shelley’s Frankenstein genom tre andra filmatiseringar / "It's alive!" : How the story of Frankenstein has changed from Mary Shelley’s original to Mary Shelley’s Frankenstein through three other movie adaptations

Thonander Lindalen, Simon January 2023 (has links)
Den här uppsatsen jämför Mary Shelleys Frankenstein: eller den moderna Prometeus med Kenneth Branaghs film Mary Shelley’s Frankenstein från 1994. Uppsatsens syfte är att se hur vissa av förändringarna från text till film kan spåras till tidigare Frankensteinadaptioner, specifikt Frankenstein och Bride of Frankenstein (1931 respektive 1935) av James Whale, och The Curse of Frankenstein (1957) av Terence Fisher. Undersökningen visar att vissa förändringar som gjorts i tidigare filmer på grund av filmernas samtid och omgivning har blivit en del av den allmänna bilden av Frankensteinberättelsen, och på så vis lever kvar även i senare filmatiseringar. Slutsatsen dras att Mary Shelley’s Frankenstein inte bara är en adaption av Mary Shelleys text, utan kan även ses som en adaption av tidigare filmskapares verk. / This essay compares Mary Shelley’s Frankenstein; or, The Modern Prometheus with Kenneth Branagh’s 1994 film Mary Shelley’s Frankenstein. The purpose of the essay is to examine how some of the changes from text to film can be traced to earlier Frankenstein adaptations, specifically Frankenstein and Bride of Frankenstein (1931 and 1935, respectively) by James Whale, and The Curse of Frankenstein (1957) by Terence Fisher. The research shows that certain changes made in earlier films due to the films’ time and place in history have become part of the general image of the Frankenstein story, and thus survive even in later film adaptations. The conclusion is drawn that Mary Shelley’s Frankenstein is not only an adaptation of Mary Shelley’s text, but can also be seen as an adaptation of previous filmmakers’ works.

Investigating the surfacing and diving behaviour and availability of long-finned pilot whales and quantifying the effects of anthropogenic sound on density and strandings of cetaceans in the northeast Atlantic

Jewell, Rebecca January 2014 (has links)
The size and trend of a population is fundamental to the assessment of its conservation status, yet cetacean abundance data are often biased and lack statistical power to detect trends. As a result, the conservation status of many species is unknown and the population-level effects of conservation pressures such as anthropogenic sound cannot be quantified. Failing to account for cetaceans that are unavailable for detection at the surface during abundance surveys will negatively bias estimates of abundance. Analysis of time-depth data revealed that pilot whale dive and surface interval durations, and availability for detection, varied with time of day, but this bias was accurately estimated using the mean dive and surface interval durations. A global analysis of cetacean density estimates compiled from multiple line-transect surveys incorporated covariates describing availability bias, and other sources of variability, to facilitate the detection of underlying temporal trends. Decadal global trends in cetacean density were detected for four species, while significant yearly ocean-scale trends were detected for six families. Exploratory analysis of data compiled from line-transect surveys found some evidence that trends in the density of minke whales and sperm whales in the northeast Atlantic varied between areas with and without seismic survey effort. However, there were insufficient data to clearly identify chronic exposure to anthropogenic sound from seismic surveys as a driver of population change. Analysis of strandings data from the UK and Ireland identified some evidence that harbour porpoise and sperm whale stranding rates were related to seismic survey effort and wind farm construction, but the results were not conclusive. Large-scale cetacean surveys provide valuable information on the density and spatial and temporal distribution of cetaceans that is vital for monitoring populations, but these surveys cannot replace dedicated studies of the population-level effects of sound on cetaceans.

Ekoturismens inverkan på miljömässiga attityder och beteenden : En kvalitativ studie om individers erfarenhet av valskådning

Åhlin, Frida, Guldbrandsen, Veronica January 2014 (has links)
The purpose of this study is to examine if the experience of whale watching can lead to increased knowledge of environmental problems. We also want to find out whether increased knowledge in turn could lead to changing environmental attitudes and behaviors. The theoretical framework consists of theories about sustainable tourism, ecotourism and responsible environmental behavior. The paper also has a section where previous research on ecotourism impacts on behavior and attitudes is discussed and subsequently addressed in the analysis section. Data has been collected through a case study where seven semi-structured interviews were conducted with individuals who participated in whale watching. The results show that all respondents had greater knowledge of whales by their experiences, the degree of knowledge was due to respondents' prior knowledge. The respondents did not consider their attitude towards environmental issues has changed considerably by the experience or that it affected their environmental behavior. A number of conclusions were drawn from analysis of empirical data using the selected theories. It seems that it is easier to give people knowledge than to influence them to change their attitudes and it is particularly difficult to say whether the experience of a single ecotourism experience may impact deeply ingrained attitudes and behaviors. Overall, the results suggest that ecotourism experiences to some extent leads to the strengthening of participants' environmental awareness and thus increase their interest in participating in further ecotourism experiences. Through these circular effects, an increased environmental knowledge provided by ecotourism experiences in the longer term can help to develop more responsible environmental attitudes and behavior of individuals. / Syftet med denna uppsats är att undersöka om upplevelsen av valskådning kan leda till ökad kunskap om miljöproblem. Vi vill också ta reda på om ökad kunskap i sin tur kan leda till förändrade miljömässiga attityder och beteenden. Uppsatsens teoretiska ramverk utgörs av teorier kring hållbar turism, ekoturism och ansvarsfullt miljömässigt beteende. Uppsatsen har även ett avsnitt där tidigare forskning kring ekoturismens inverkan på beteende och attityder diskuteras för att därefter behandlas i analysdelen. Uppsatsens empiri har samlats in genom en kvalitativ studie där sju semistrukturerade intervjuer har genomförts med individer som deltagit i valskådning. Resultaten visar att samtliga respondenter fick ökad kunskap om valar av sina upplevelser, hur hög grad av kunskap berodde dock på respondenternas förkunskap. Respondenterna ansåg inte att deras attityder gentemot miljöfrågor förändrats avsevärt av upplevelsen eller att det påverkat deras miljömässiga beteende. Ett antal slutsatser har dragits utifrån analys av empiri med hjälp av valda teorier. Det verkar som att det är lättare att ge människor kunskap än att påverka dem att ändra sina attityder och det är särskilt svårt att säga om erfarenhet av en enda ekoturistisk upplevelse kan ha effekt på djupt inrotade attityder och beteenden. Sammantaget tyder resultaten på att ekoturistiska erfarenheter till viss del leder till att förstärka deltagarnas miljömedvetenhet och därmed också öka deras intresse för att delta i ytterligare ekoturistiska upplevelser. Genom dessa cirkulära effekter kan ökad miljökunskap som tillhandahålls genom ekoturistiska upplevelser i ett längre perspektiv bidra till att utveckla mer ansvarsfulla miljömässiga attityder och beteenden hos individer.
