The whale shark is the world's largest fish that forms predictable aggregations across its range, many of which support tourism industries. The largest non-captive provisioned whale shark destination globally is at Oslob, Philippines, where more than 500 000 tourists visit yearly. There, the sharks are provisioned daily, year-round, allowing the human–shark interaction in nearshore waters. We used in-water behavioural observations of whale sharks between 2015 and 2017 to understand the relationship between external stimuli and shark behaviour, whether frequency of visits at the site can act as a predictor of behaviour, and the tourist compliance to the code of conduct. Mixed effects models revealed that the number of previous visits at the site was a strong predictor of whale shark behaviour, and that provisioned sharks were less likely to exhibit avoidance. Compliance was poor, with 93% of surveys having people less than 2 m from the animal, highlighting overcrowding of whale sharks at Oslob. Given the behavioural implications to whale sharks highlighted here and the local community's reliance on the tourism industry, it is imperative to improve management strategies to increase tourist compliance and strive for sustainable tourism practices.

Breast cancer is a potential traumatic event associated with psychological symptoms, but few studies have analysed its impact in under-50 women. Emotional processing is a successful function in integrating traumatic experiences. This work analysed the relationship between emotional processing and psychological symptoms during three phases of treatment (before hospitalization, counselling after surgery and adjuvant therapy) in 50 women under the age of 50 with breast cancer. Mixed-effects models tested statistical differences among phases. There were significant differences in symptoms during the treatments: the levels of anxiety decrease from T1 to T3 (0.046), while those of hostility increase (<0.001). Emotional processing is a strong predictor of all symptoms. Clinical implications are discussed.

Abstract This research communication describes the relationship between the occurrence of lameness and body condition score (BCS) in a sample of 288 cows from a single farm that were repeatedly scored in the course of 9 months while controlling for confounding variables. The relationship between BCS and lameness was evaluated using generalised linear mixed-effects models. It was found that the proportion of lame cows was higher with decreasing but also with increasing BCS, increased with lactation number and decreased with time since the last claw trimming. This is likely to reflect the importance of sufficient body condition in the prevention of lameness but also raises the question of the impact of overcondition on lameness and the influence of claw trimming events on the assessment of lameness. A stronger focus on BCS might allow improved management of lameness that is still one of the major problems in housed cows.

This exploratory study examined the relationship between corrective feedback (CF) and linguistic target complexity. In a pre-test/post-test/delayed post-test design, 44 adult intermediate L2 Italian learners from different L1 backgrounds were assigned to a didactic recast, a prompt and a no-feedback group. They were compared on oral and written measures on the development of passato prossimo, an Italian compound past form characterised by a set of complex semantic and morphosyntactic rules and participles displaying different degrees of form-meaning transparency. Mixed-effects models elucidated the extent to which feedback frequency predicted accuracy, whilst controlling for the effect of individual difference covariates and random variation. Only the frequency of didactic recasts predicted development of full passato prossimo sentences, whereas both feedback types were significantly related to participle development, a single aspect of the construction. Furthermore, only prompt frequency was positively related to accuracy in participles displaying more transparent (less complex) form-meaning relationships.

Background. Provisioning is a growing practice used to facilitate wildlife-tourist interaction, especially with elusive marine species, but still little is known about its effect on the host species. This work discusses the practice, effect and proposed measures to manage the whale shark provisioning activities and related tourism industry in the waters of Oslob, Philippines. Methods. Since March 2012, the research team has been studying daily the whale shark population, the tourism industry and its compliances with the local and national laws. During 443 days of survey, 135 individual whale sharks where identified within the interaction area, 197h of shark behavioral observations and tourist compliance surveys have been collected along with 45 biopsy samples, 1000h of dive profiles from TDR tags and 500 tourist satisfaction questionnaires. Results. Since its official opening in January 2012 more than 140,000 interaction tickets have been sold bringing over 1M USD to the local community and making it one of the largest marine wildlife tourist attractions in South East Asia. The benefits for the community and regional economy are undeniable, however behavioral modification, extended residency time, poor nutritional value of provided food and thermal stress related to the extended permanence in shallow water together with habitat destruction caused by poor diving practices and unregulated coastal developments are some of the quantified side effects of this industry. Conclusion. A series of meeting with the stakeholders and an education campaign have been initiated as bottom up approach and an adaptive management model based on the identification of the limits of acceptable change is being developed in collaboration with the Authorities to address current limitations in the long-term sustainable management of the whale shark watching industry in Oslob.

Nosy Be in northwestern Madagascar is home to a globally important whale shark (Rhincodon typus) aggregation and a growing whale shark tourism industry. Whale sharks, however, are not protected in Malagasy waters and are threatened by fisheries bycatch, collisions with vessels, and disturbance from tourism. We used tourist questionnaires (n = 488) to assess the economic value of, and tourist perceptions of, whale shark tourism in Nosy Be from September-December 2019. We also surveyed whale shark tour operators (n = 12) in December 2018 to understand their perceptions of tourism management needs in the region. Results suggest the Nosy Be whale shark tourism industry was worth US$1.5 million for the three-month 2019 whale shark season. ‘Dedicated’ whale shark divers (i.e., those who came specifically to Nosy Be to swim with whale sharks) spent 55% more money overall and six times the amount individually compared to ‘casual’ whale shark divers. Both tourists and operators supported the protection of whale sharks, with the majority (67.4%) of tourists strongly agreeing that they would choose a tourism destination at which whale sharks are protected. Tour operators did note, however, significant management issues (e.g., overcrowding, lack of regulations/training), recommending the need to better regulate whale shark tourism and interactions. This study emphasises the economic rationale for protecting whale sharks in Madagascar to safeguard the emerging marine tourism industry and ensure it is being sustainably managed.

Nature and environment are important for the people earning their living from natural sources of livelihood. This article concentrates on the local perspective of the landscape in the Pallastunturi Fells, which are situated in Pallas-Ylläs National Park in Finnish Lapland. The Fells are both important pastures for reindeer and an old tourism area. The Pallastunturi Tourist Hotel is situated inside the national park because the hotel was built before the park was established 1938. Until the 1960s, the relationship between tourism and reindeer herding had been harmonious because the tourism activities did not disturb the reindeer herding, but offered instead ways to earn money by transporting the tourists from the main road to the hotel, which had been previously without any road connections. During recent years, tourism has been developed as the main source of livelihood in Lapland and huge investments have been made in several parts of Lapland. One example of this type of investment is the plan to replace the old Pallas Tourist hotel, which was built in 1948, with a newer and bigger one. It means that the state will allow a private enterprise to build more infrastructures for tourism inside a national park where nature should be protected and this has sparked a heated debate. Those who oppose the project criticise this proposal as the amendment of a law designed to promote the economic interests of one private tourism enterprise. The project's supporters claim that the needs of the tourism industry and nature protection can both be promoted and that it is important to develop a tourist centre which is already situated within the national park. This article is an attempt to try to shed light on why the local people are so loudly resisting the plans by a private tourism enterprise to touch the national park. It is based on my fieldwork among reindeer herding families in the area.

Part I of this book is an in-depth examination of the characteristics of the Tuscan aristocracy across the first two and a half centuries of the second millennium, as studied by Italian historians and others working within the Italian tradition: their origins, interests, strategies for survival and exercise of power; the structure and the several levels of aristocracy and how these interrelated; the internal dynamics and perceptions that governed aristocratic life; and the relationship to non-aristocratic sectors of society. It will look at how aristocratic society changed across this period and how far changes were internally generated as opposed to responses from external stimuli. The relationship between the aristocracy and public authority will also be examined. Part II of the book deals with England. The aim here is not a comparative study but to bring insights drawn from Tuscan history and Tuscan historiography into play in understanding the evolution of English society from around the year 1000 to around 1250. This part of the book draws on the breadth of English historiography but is also guided by the Italian experience. The book challenges the interpretative framework within which much English history of this period tends to be written—that is to say the grand narrative which revolves around Magna Carta and English exceptionalism—and seeks to avoid dangers of teleology, of idealism, and of essentialism. By offering a study of the aristocracy across a wide time-frame and with themes drawn from Italian historiography, I hope to obviate these tendencies and to appreciate the aristocracy firmly within its own contexts.
