Wood Dust and Nasopharynx and Sinonasal Cancer
Millions of workers around the world are exposed to wood dust, as a by-product of woodworking. Nasopharynx cancers (NPCs) and sinonasal cancers (SNCs) are two cancers that can be caused by occupational exposure to wood dust, but there is little evidence regarding their burden in Canada.

List of Countries by Wealth Equality
This is a list of countries by distribution of wealth, including Gini coefficients. Wealth distribution can vary greatly from income distribution in a country (see List of countries by income equality). Higher Gini coefficients signify greater inequality in wealth distribution, with 0 being complete equality, whereas a value near 1 can arise in a situation where everybody has zero wealth except a very small minority. It is a common misconception that Scandinavian countries have low wealth inequality. This is not true. These countries have low income inequality, meaning that the income is relatively equal for everyone. However, their wealth inequality is very high, meaning that a small minority of the people owns the vast majority of wealth.

Perceived Value’ Predictive Relationship
Ecotourism development is a distinct market phenomenon and a necessary form of sustainable tourism, which grows three times faster than tourism in general. Ecotourism’s rising popularity worldwide has encouraged tourist destinations to receive more and more tourists who like contact with nature and are willing to comply with the protection standards of the natural area chosen.

Sustainability in Rural Tourism
Ventures in rural areas face multiple constraints, in many circumstances worsened by their reduced size and their location in the national territory. Small ventures in this specific context face a reality in which entrepreneurs have to overcome various difficulties in managing and making their business competitive, such as the access to human resources and a diversified labor pool. A recent debate on “rural entrepreneurship” suggests than one of the best opportunities to develop rural areas is linked with rural tourism, since its principles are related to the creation of jobs and income in the rural space and can also help to increase the perception of value of endogenous resources and products. Rural tourism entrepreneurs try to be embedded in the rural space, thereby increasing their chances of success and sustainability of the business. At the same time, with this attitude of embeddedness, they can contribute more easily to the sustainability of the region and help in shaping and voicing the need and aspirations of the stakeholders of the (rural) destination, one of the advocated principles of rural tourism.

Youth Associations and Entrepreneurship
The development of skills for entrepreneurship among young people has attracted interest at various levels, as a way of overcoming many problems that affect this group in the areas of economic development and job creation. It was possible to verify that youth associations assume a dual role, on the one hand contributing to the personal, social and professional development of its leaders, members and participants, and on the other hand, as a promoter of social transformation, particularly at the local level.

Superconductivity and Hydrogen Economy
Hydrogen as an energy carrier is a promising alternative to fossil fuels, and it becomes more and more popular in developed countries as a carbon-free fuel. The low boiling temperature of hydrogen (20 K or −253.15 °C) provides a unique opportunity to implement superconductors with a critical temperature above 20 K such as MgB2 or high-temperature superconductors. Superconductors increase efficiency and reduce the loss of energy, which could compensate for the high price of LH2 to some extent. Norway is one of the pioneer countries with adequate infrastructure for using liquid hydrogen in the industry, especially in marine technology where a superconducting propulsion system can make a remarkable impact on its economy. Using superconductors in the motor of a propulsion system can increase its efficiency from 95% to 98% when the motor operates at full power. The difference in efficiency is even greater when the motor does not work at full power.

EU ETS system
To facilitate greenhouse gas reduction, the European Commission (EC) announced its plan to introduce an ETS by 2005. Between 2005 and 2007, Phase I was conducted for 25 EU members. Starting in 2008, Phase II was expanded to 31 member countries, including new members. Phase III is in operation between 2013 and 2020, and Phase IV is scheduled to run from 2021 to 2030.The changes and development in the EU ETS system increase the informational efficiency of the carbon market and contribute to actual emissions' reductions.

Experimental Economics
Experimental economics is the application of experimental methods to study economic questions. Data collected in experiments are used to estimate effect size, test the validity of economic theories, and illuminate market mechanisms. Economic experiments usually use cash to motivate subjects, in order to mimic real-world incentives. Experiments are used to help understand how and why markets and other exchange systems function as they do. Experimental economics have also expanded to understand institutions and the law (experimental law and economics). A fundamental aspect of the subject is design of experiments. Experiments may be conducted in the field or in laboratory settings, whether of individual or group behavior. Variants of the subject outside such formal confines include natural and quasi-natural experiments.

Insights from Circular Economy Literature
The circular economy (CE) has become one of the prominent topics in both natural science and management literature over the last few decades. CE is a dual-loop regenerative system that focuses on the effective and efficient utilization of resources in the ecosystem, which is beneficial to environmental and economic performance optimization. Dual CE initiatives allow firms to increased resource eco-efficiency, as well as resource effectiveness.

Bibliometric Analysis of Supplier Management
This entry presents the results of a bibliometric analysis of supplier management. We conducted a bibliometric analysis based on 4687 papers on supplier management from 1997 to 2017. Through a comparative analysis of the four stages using Bibexcel and Ucinet6 software, this paper explores the evolution of supplier management from the theme and cluster perspectives. The results show that supplier management research has made breakthroughs in both breadth and depth. Representative research themes, such as “sustainable supply chain”, “corporate social responsibility”, “knowledge management”, etc., have gradually penetrated into the field of supplier management. Research related to “supplier selection” and “supplier relations” have always been of the highest strategic importance, and themes in “supplier relations” cluster such as “trust” and “commitment” have gradually attracted more and more researchers' attention. The “inventory” cluster has also been a research focus, and the structural stability and maturity of the cluster have gradually improved. The “innovation” cluster is a relatively “open” cluster, and its impact on the entire research filed of supplier management has been gradually increasing. More importantly, the “sustainability” cluster is an evolving cluster, research themes related to “sustainability”, such as “green supply chain”, “sustainable supply chain” and “green supplier selection”, will play an increasingly important role in the field of supplier management.

Population Projections
Population projections serve various actors at sub-national, national, and international levels as a quantitative basis for political and economic decision-making. Often, the users are no experts in statistics or forecasting and therefore lack the methodological and demographic background to completely understand the methods and limitations behind the projections they use for their analyses. Our contribution primarily targets that readership.

EU Timber Regulation
Illegal logging and the associated deforestation have serious consequences for biodiversity, the climate, the economy and society. The EU Timber Regulation (EUTR) prohibits the placing of illegally harvested timber or timber products on the market. The objective of this paper is to analyse the recent evolution of EU imports of these products from the international market, in order to check how the transparency index of the supplying countries’ institutions and tree cover loss have influenced this trajectory. To that end, a panel data model is estimated with 228 observations from 38 exporting countries between 2012 and 2017. The results show that EU timber imports have a direct association with the transparency index and an inverse relationship with tree cover loss; both these relationships are highly significant at the one-percent level. Other significant factors are the performance of the EU construction sector (as a proxy for timber demand) and timber supply. In the short and medium-term, Voluntary Partnership Agreements (VPAs) signed between the EU and non-EU timber-producing countries have a negative influence on the supply to EU member states. This study presents an analysis of EU timber imports after the implementation of the EUTR, providing specific conclusions that can inform policymakers’ efforts to foster sustainable forest management.

Information and Communication Technology and CO2 Emissions
The expansion of ICT has led to higher electricity consumption due to the increase in ICT terminal devices, networks, and large-scale data centers, resulting in an increase in power consumption. Data centers, in particular, contain IT hardware, such as computers and data storage devices; various types of network equipment for communication (routers, switches, modems, etc.); and heating and cooling infrastructure. The energy used by data centers is 10–100 times that compared to the amount used by commercial buildings in the same area. According to UNEP and DTU, the amount of electricity consumed by data centers in 2018 corresponded to 1% of the global electricity demand, but it is expected to account for more than 20% of the total electricity demand in 2030. If ICT electricity consumption increases at the current rate, it will have a negative impact on reducing CO2 emissions. In other words, the expansion of ICT equipment supply accompanies the demand for electricity in terms of use, which leads to an increase in CO2 emissions.

Religion in Human Consumption
Religious belief, as an informal social institution, has a significant impact on all aspects of human civilization. Specifically, in the western area of China, low income level, and low marketization degree, religious belief negatively affects human consumption the most. On the contrary, in the eastern area, high income level, and high marketization degree, religious belief negatively affects human consumption the least.

San Antonio Independent School District V. Rodriguez
San Antonio Independent School District v. Rodriguez, 411 U.S. 1 (1973), was a case in which the Supreme Court of the United States held that San Antonio Independent School District's financing system, which was based on local property taxes, was not an unconstitutional violation of the Fourteenth Amendment's equal protection clause. The majority opinion, reversing the District Court, stated that the appellees did not sufficiently prove a textual basis, within the US Constitution, supporting the principle that education is a fundamental right. Urging that the school financing system led to wealth-based discrimination, the plaintiffs had argued that the fundamental right to education should be applied to the States, through the Fourteenth Amendment. The Court found that there was no such fundamental right and that the unequal school financing system was not subject to strict scrutiny.
