The purpose of this paper is to investigate the effect of numerical boundary condition implementation on local error and convergence in L2-norm of a finite volume discretization of the transient heat conduction equation subject to several boundary conditions, and for cases with volumetric heat generation, using both fully implicit and Crank-Nicolson time discretizations. The goal is to determine which combination of numerical boundary condition implementation and time discretization produces the most accurate solutions with the least computational effort.

The paper studies several benchmark cases including constant temperature, convective heating, constant heat flux, time-varying heat flux, and volumetric heating, and compares the convergence rates and local to analytical or semi-analytical solutions.

The Crank-Nicolson method coupled with second-order expression for the boundary derivatives produces the most accurate solutions on the coarsest meshes with the least computation times. The Crank-Nicolson method allows up to 16X larger time step for similar accuracy, with nearly negligible additional computational effort compared with the implicit method.

The findings can be used by researchers writing similar codes for quantitative guidance concerning the effect of various numerical boundary condition approximations for a large class of boundary condition types for two common time discretization methods.

The paper provides a comprehensive study of accuracy and convergence of the finite volume discretization for a wide range of benchmark cases and common time discretization methods.

The discovery of internet technologies which is one of the most important developments of the twenty-first century has enabled individuals and institutions to overcome geographical and time constraints creating fundamental changes in communication. As a result, online communities have enabled people to meet the internet for various reasons such as seeking and sharing information, discuss community issues and ask questions; and online communities have also enabled businesses and consumers to connect with each other at any time. Especially the emergence of Internet-based social media technologies such as blogs, virtual communities, wikis, social networks, YouTube, Facebook and Instagram provides tourists to share their travel experiences. Information shared on social media sites is considered to be an important source of information that can help tourists’ travel plan and may even influence the travel decisions of potential tourists. In this context, the concept of social media in tourism businesses has been examined in the research. Within the framework of the research, it has been observed that social media has influenced the tourists’ behavior regarding travel motivations in the context of various motivations (having information about destinations, hotels, services of hotels, wondering about consumers’ experiences who were in touristic consumption before, etc.). It is also among other findings that social media has increased the overtourism crisis.

Drawing on the author's multi‐method research on the viability of specific ecotherapy practitioner training and curriculum design, this paper debates how the use of ecotherapeutic approaches can provide a two‐pronged system to achieve both individual health (at micro level) and public and environment health outcomes (at macro level). The research sought the views of service users, practitioners and educationalists through use of interviews, focus groups, a nominal group, and an ethnographic case study group. This research raised other considerations: namely, that people seeking personal recovery also, through stewardship of green spaces, may achieve unanticipated social capital and natural capital outcomes and thereby meet current multi‐disciplinary policy targets. This added social value has not been previously considered as an important dimension in people's well‐being and recovery from ill health or social exclusion. Such outcomes emerge from the idea of green spaces becoming a ‘product’ delivered to the community by people whose pursuit of personal recovery also directly contributes to improved public mental health.

In 1992 Joe Jackson, former manager of DuPont Motorsports for twelve years, was angling to get the paint business at Rick Hendrick's sixty-five automotive dealerships across the United States. In order to win the Hendrick car dealership paint contract, Jackson and Hendrick met to discuss the possibility of sponsoring Hendrick's new team and rookie NASCAR driver—Jeff Gordon. As a result of that meeting, DuPont signed on to be the primary sponsor. By 2006 Gordon was a NASCAR superstar, and the DuPont logo—viewed by millions—was a household brand. While this level of exposure was exciting for the company, executives at DuPont could not help but wonder if they were fully leveraging this tremendous marketing opportunity. Gordon was on fire—but was DuPont maximizing the heat? The DuPont-NASCAR case tasks students and executives with designing a creative marketing campaign to activate the NASCAR sponsorship opportunity and maximize value beyond conventional sponsorship marketing. This open-ended challenge encourages students and executives to think outside of the traditional marketing tactics typically employed by business-to-consumer (B2C) NASCAR sponsors. Additionally, the nature of DuPont creates the need to develop a multi-dimensional plan that caters to a breadth of brands. Beyond designing a new marketing campaign, a key objective of the case is to focus students and executives on designing metrics for measurement of the return on investment (ROI) into a campaign plan. As a first step, it is important to clearly articulate the campaign, business strategy, and key business objectives mapped to the strategy.

Students and executives learn how to design a marketing campaign for measurement. Specifically, they are tasked with designing a new marketing campaign for DuPont to activate the DuPont/NASCAR relationship. Students and executives must define metrics for measurement and learn to use a balanced score card approach. Since the DuPont sponsorship of Hendrick Motorsports is a brand campaign built to reach the DuPont business-to-business (B2B) customer, both non-financial and financial metrics are used. The key to success is to have a clearly defined sponsorship marketing strategy and business objectives. The case teaches students and executives how to define key metrics and articulate a methodology for campaign measurement pre and post to quantify the return on investment (ROI).

To examine the relationship between financial resources and variables associated with institutional rankings in the USA.

Pearson product moment correlation coefficient was used to investigate the relationship between endowment funds and variables associated with rankings as determined by the U.S. News & World Report.

College costs continue to increase faster than per capita income. Institutions are relying more on endowment funds to meet their needs. Endowment was positively associated with almost all the variables used for ranking top national doctoral universities with the largest endowment amounts. When endowment per student was used, the association became even stronger with these ranking variables. Endowment was weakly associated with almost all the variables used for ranking top national doctoral universities with the lowest endowment amounts. Relationships of endowment and ranking variables were stronger at medical research schools, business schools, and weaker at engineering schools.

Higher education administrators must realize that these variables are cost‐inducing factors that cannot be fully satisfied. Unbridled pursuit of ranking variables will increase cost without commensurate increase in educational quality. Therefore, leaders must decide what rankings their resources allow and what position within the ranks is acceptable to them. Ranking agencies interested in quality should realize that money plays a significant role in how an institution is ranked. Therefore, institutions should be grouped according to the available resources before comparative analysis of ranking variables is made.

The purpose of this paper is to identify and review attempts at mitigation and prevention of overtourism and to outline reasons for the failure to date of such efforts.

This paper is a perspective paper and draws on an examination of relevant literature on the subject through the lens of a conceptual framework. It outlines the changing roles of tourism development and marketing organisations and the failure of public sector agencies to control and manage tourism. The varying methods of limiting tourist numbers are examined, and their weaknesses are presented.

Conclusions reveal that there are a series of global trends that are contributing to the appearance and continuation of overtourism and which, to date, are proving immune to mitigation and resolution for specific reasons. These include a lack of willingness to accept the problem of tourist numbers and to reduce or effectively manage these at all levels, from local to international.

Present approaches to mitigation need to be revisited and better integrated with management and control of all aspects of development and framed to achieve and retain political support at all levels.

There has been little attempt before to analyse the reasons for the failure to effectively mitigate or prevent overtourism, and this paper makes an original contribution in this area in that it is an evaluation of what is known and a summary of shortcomings within the industry and academia.

La finalidad de este trabajo es identificar y revisar los intentos de mitigación y prevención de la saturación turística y esbozar las razones del fracaso hasta la fecha de dichos esfuerzos.

Las conclusiones revelan que existen una serie de tendencias globales que están contribuyendo a la aparición y continuidad de la saturación turística y que, hasta la fecha, están demostrando ser inmunes a la mitigación y resolución por razones específicas. Éstas incluyen la falta de voluntad para aceptar el problema del número de turistas y reducirlos o gestionarlos de manera eficaz en todos los niveles, desde el ámbito local hasta el internacional.

El trabajo analiza lo que se considera como las razones del fracaso para resolver la saturación turística en muchos destinos turísticos. Los enfoques actuales para la mitigación necesitan ser revisados e integrarse mejor con la gestión y el control de todos los aspectos del desarrollo, y deben enmarcarse para lograr y mantener el apoyo político en todos los niveles.

Se identifican las áreas potenciales para un mayor estudio, así como nuevas aplicaciones y, por tanto, presenta implicaciones prácticas para las organizaciones que gestionan los destinos. En particular, los enfoques actuales de mitigación deben revisarse e integrarse mejor con la gestión y el control de todos los aspectos del desarrollo, y deben enmarcarse para lograr y retener el apoyo político en todos los niveles y ser efectivos.

La saturación turística es un problema social en la mente de muchas personas y el documento explica por qué este problema ha demostrado ser difícil de resolver. La evaluación de los fracasos del pasado debería permitir a los residentes de los destinos turísticos abogar por medidas diferentes y más eficaces y, en particular, para que esas medidas se apliquen correctamente.
