AbstractAmid declining shark populations because of overfishing, a burgeoning shark watching industry, already well established in some locations, generates benefits from shark protection. We compile reported economic benefits at shark watching locations and use a meta-analytical approach to estimate benefits at sites without available data. Results suggest that, globally, c. 590,000 shark watchers expend > USD 314 million per year, directly supporting 10,000 jobs. By comparison, the landed value of global shark fisheries is currently c. USD 630 million and has been in decline for most of the past decade. Based on current observed trends, numbers of shark watchers could more than double within the next 20 years, generating > USD 780 million in tourist expenditures around the world. This supports optimistic projections at new sites, including those in an increasing number of shark sanctuaries established primarily for shark conservation and enacted in recognition of the ecological and economic importance of living sharks.

Shark Fisheries

Abstract Current shark conservation and management conflicts represent an underrecognized expression of long-standing debates over whether the goal of modern conservation should be sustainable exploitation of natural resources or maximum possible preservation of wilderness and wildlife. In the developing world, exploitation of fisheries resources can be essential to food security and poverty alleviation, and management is typically focused on sustainably maximizing economic benefits. This approach aligns with traditional fisheries management and the perspectives of most surveyed scientific researchers who study sharks. However, in Europe and North America, sharks are increasingly venerated as wildlife to be preserved irrespective of conservation status, resulting in growing pressure to prohibit exploitation of sharks and trade in shark products. To understand the causes and significance of this divergence in goals, we surveyed 155 shark conservation focused environmental advocates from 78 environmental non-profits, and asked three key questions: (1) where do advocates get scientific information? (2) Does all policy-relevant scientific information reach advocates? and (3) Do advocates work towards the same policy goals identified by scientific researchers? Findings suggest many environmental advocates are aware of key scientific results and use science-based arguments in their advocacy, but a small but vocal subset of advocates report that they never read the scientific literature or speak to scientists. Engagement with science appears to be the key predictor of whether advocates support sustainable management of shark fisheries or bans on shark fishing and trade in shark products. Conservation is a normative discipline, and this analysis more clearly articulates two distinct perspectives in shark conservation. Most advocates support the same evidence-based policies as academic and government scientists, while a smaller percentage are driven more by moral and ethical beliefs, and may not find scientific research relevant or persuasive. A values-based perspective is also a valid approach to conservation, but claiming that it is a science-based approach while misrepresenting the science is problematic. This suggests possible alternative avenues for engaging diverse stakeholders in productive discussions about shark conservation.

This study estimated the economic value of the shark-diving industry in Semporna, the most popular diving destination of Malaysia, by surveying the expenditures of diving tourists and dive operators through the region. A willingness-to-pay survey was also used to estimate the potential of the industry as a financing mechanism for enforcement and management of a hypothetical shark sanctuary. The study showed that in 2012, shark-diving tourism provided direct revenues in excess of USD 9.8 million to the Semporna district. These economic benefits had a flow-on effect, generating more than USD 2 million in direct taxes to the government and USD 1.4 million in salaries to the community. A contingent valuation analysis indicated that implementation of a fee paid by divers could generate over USD 2 million for management and enforcement of a shark sanctuary each year. These findings suggest that shark diving is an important contributor to the economy of the Semporna region that could be used as a mechanism to assist financial resourcing for management and conservation strategies.

Survival and advancement of nations is attributed to their literatures. This is because literatures enable individuals to transcend the material life and be able to visualize the noble meanings and the world of aesthetics. Indeed, a language is the best level of describing self and others as it does not originate from the ego, but rather from the laws of the universe and existence. Moreover, it is not only a lexicon, but also a combination of words, indications, gestures, spaces, and imagery. It is, hence, possible to realize the significance of poetry as a definition of all the previous elements. Tashteer is a type of poetic art where a poet does not invent a new idea but rather adopts the idea of poetry by another poet. The poet follows the meter and rhyme set by the original poet, and thus is not allowed much space for creating a purpose apart from the original one. Therefore, a poet is confined to the predefined purpose and notion in terms of grammatical, syntactic and semantic aspects. The paper focuses on the study of the art of Tashteer of poet Ali al-Deeb who performed Tashteer on the poet of Abi Firaas (Araaka `Asaiyya al-Dam`). The study aims to introduce the art of Tashteer by addressing its practical aspect. The study also uses the descriptive analytical approach to illustrate the strength points of Mushatir (a poet performing Tashteer) and compare his poet with the original one in terms of serving the concept. The study comprises two parts; Part one is for defining the art of Tashteer in the Arabian poetry. Part two includes the analytical study of the poetry under Tashteer. The study concluded several findings including: al-Deeb clearly comprehended the purposes that Abi Firaas had in his poetry. Thus, he was able to have hold of the main notion of the text both linguistically and semantically. He was even able to penetrate into some of the lines and reveal the thoughts.

Mayoral Leadership

With globalization, the largest cities in the world have been growing in economic importance. And their local powers have often been enhanced as a result of decentralization reforms over the past two decades. In this context, cities—and particularly their mayors—have been reaching out to other cities and jurisdictions to pursue a variety of goals. One term for this process is “paradiplomacy,” but most of the literature on the subject gives little attention to the local political dynamics behind these initiatives. In this article, we explore these local dynamics through a comparison of two major cities, Toronto, Canada, and São Paulo, Brazil. The cases show that external initiatives, both in scope and direction, vary according to the political strategies of the elected mayors. These strategies are strongly affected by the local context and by the political logic of mayoral leadership.

Instrument Control

Advances in camera technology and digital instrument control have meant that in modern microscopy, the image that was, in the past, typically recorded on a piece of film is now recorded directly into a computer. The transfer of the analog image seen in the microscope to the digitized picture in the computer does not mean, however, that the problems associated with recording images, analyzing them, and preparing them for publication, have all miraculously been solved. The steps involved in the recording an image to film remain largely intact in the digital world. The image is recorded, prepared for measurement in some way, analyzed, and then prepared for presentation.Digital image acquisition schemes are largely the realm of the microscope manufacturers, however, there are also a multitude of “homemade” acquisition systems in microscope laboratories around the world. It is not the mission of this tutorial to deal with the various acquisition systems, but rather to introduce the novice user to rudimentary image processing and measurement.

On the Symbolism of Rain in A Farewell to Arms

Farewell To Arms

This paper critically analyzes the symbolic use of rain in A Farewell to Arms (1929). The researcher has applied the Sapir-Whorf Hypothesis as a research tool for the analysis of the text. This hypothesis argues that the languages spoken by a person determine how one observes this world and that the peculiarities encoded in each language are all different from one another. It affirms that speakers of different languages reflect the world in pretty different ways. Hemingway’s symbolic use of rain in A Farewell to Arms (1929) is denotative, connotative, and ironical. The narrator and protagonist, Frederick Henry symbolically embodies his own perceptions about the world around him. He time and again talks about rain when something embarrassing is about to ensue like disease, injury, arrest, retreat, defeat, escape, and even death. Secondly, Hemingway has connotatively used rain as a cleansing agent for washing the past memories out of his mind. Finally, the author has ironically used rain as a symbol when Henry insists on his love with Catherine Barkley while the latter being afraid of the rain finds herself dead in it.

The Way

The world-wide use of scleral contact lenses has dramatically increased over the past 10 year and has changed the way that we manage patients with corneal irregularity. Successfully fitting them can be challenging especially for eyes that have significant asymmetries of the cornea or sclera. The future of scleral lens fitting is utilizing corneo-scleral topography to accurately measure the anterior ocular surface and then using software to design lenses that identically match the scleral surface and evenly vault the cornea. This process allows the practitioner to efficiently fit a customized scleral lens that successfully provides the patient with comfortable wear and improved vision.

National Borders

Over the past century, democracy spread around the world in turbulent bursts of change, sweeping across national borders in dramatic cascades of revolution and reform. This book offers a new global-oriented explanation for this wavelike spread and retreat—not only of democracy but also of its twentieth-century rivals, fascism, and communism. The book argues that waves of regime change are driven by the aftermath of cataclysmic disruptions to the international system. These hegemonic shocks, marked by the sudden rise and fall of great powers, have been essential and often-neglected drivers of domestic transformations. Though rare and fleeting, they not only repeatedly alter the global hierarchy of powerful states but also create unique and powerful opportunities for sweeping national reforms—by triggering military impositions, swiftly changing the incentives of domestic actors, or transforming the basis of political legitimacy itself. As a result, the evolution of modern regimes cannot be fully understood without examining the consequences of clashes between great powers, which repeatedly—and often unsuccessfully—sought to cajole, inspire, and intimidate other states into joining their camps.
