Cost-Benefit Analysis
Cost-benefit analysis (CBA) is a method that is used for making investment decisions in public and private sector, and comparing benefits and costs resulting from the investments. This method attempts to determine present value of potential benefits and costs of any intended investment, and selects the project with the most benefits by comparing various projects designed for the investment.

Food Insecurity and Obesity
An interesting paradox is observed in terms of access to proper nutrition in the United States and in much of the world. In the United States, as much as 40% of the total food resources generated is wasted, while simultaneously, 5.6 million households exhibit disrupted eating patterns and reduced food intake due to financial or other access-related issues. The disrupted eating patterns and improper nutrition can lead to increased risk of diet-related disease onset especially for chronic diseases such as heart disease, Obesity, hypertension and Type 2 Diabetes Mellitus (T2DM). The discussion herein focuses on the inter-relationship among the following factors: access to proper nutrition, obesity, T2DM, and food waste.

Crowdfunding
Crowdfunding is the practice of funding a newly created firm or project by raising funds from a large number of people. It is usually performed online. In 2009 the volume of funds raised using crowdfunding was negligeably small. Crowdfunding raised $34.4 billion in 2015. Some analysts predict that crowdfunding market size will grow at an annual rate of 27.8% and will surpass venture capital investments in the near future (Miglo and Miglo, 2019).

Schools, Air Pollution, and Active Transportation
An exploratory spatial analysis investigates the location of schools in Calgary (Canada) in relation to air pollution and active transportation options. Air pollution exhibits marked spatial variation throughout the city, along with distinct spatial patterns in summer and winter; however, all school locations lie within low to moderate pollution levels. Conversely, the study shows that almost half of the schools lie in low walkability locations; likewise, transitability is low for 60% of schools, and only bikability is widespread, with 93% of schools in very bikable locations. School locations are subsequently categorized by pollution exposure and active transportation options. This analysis identifies and maps schools according to two levels of concern: schools in car-dependent locations and relatively high pollution; and schools in locations conducive of active transportation, yet exposed to relatively high pollution. The findings can be mapped and effectively communicated to the public, health practitioners, and school boards. The study contributes with an explicitly spatial approach to the intra-urban public health literature. Developed for a moderately polluted city, the methods can be extended to more severely polluted environments, to assist in developing spatial public health policies to improve respiratory outcomes, neurodevelopment, and metabolic and attention disorders in school-aged children.

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.

Social Networks among University Youth
This article addresses the design and validation of an updated questionnaire that makes it possible to understand the use patterns and attitudes of university youth on social networks. The authors utilized a panel of 20 judges who were social media experts and a sample of 640 university students. The exploratory factor analysis (EFA) explained 66.523% of the total variance. The confirmatory factor analysis (CFA), carried out to verify the dimensional structure of the instrument, reflected the appropriate parameters. The reliability study showed a Cronbach’s alpha of 0.864. These data corroborated the development of a robust and reliable questionnaire. The resulting instrument did not contain items alluding to specific social networks (Facebook, Twitter, Instagram, or LinkedIn), but rather students’ usage patterns of them. The exclusion of items that referred to particular social networks during the research demonstrated a convergence in behavior on social media regardless of the nuances of each platform. This fact suggested that the platform was of secondary importance in the context of a new paradigm in which the type of use (viewing, posting, participating, or interacting) took precedence over the name of the network itself.

Precautionary demand for cash
       We have recently seen two conflicting trends in the use of cash. The share of e-payments in retail transactions is steadily increasing, but the same upward trend is true for the share of cash in circulation or at least the cash share remained unchanged. This paper shows the significance of perceived risk for consumers’ precautionary demand for cash after they make a decision to use e-payments. We use data from a study involving Polish consumers. The main conclusions are as follows: surveyed consumers perceive a level of risk associated with card and mobile payments and continue to carry cash for precautionary reasons. Factors such as the consumer’s mental state, lack of trust in e-payments, and attitude to risk influence the decision to maintain cash reserves, while the consumer’s income and age may be considered the main determinants of the value of the cash reserve. Consequently, the decision to use e-payments does not necessarily mean that the demand for cash drops to zero. A degree of difficult-to-reduce, autonomous demand for cash may exist independent of the traditionally studied determinants, in particular, those related to the transaction demand.

Sustainable Employability
Sustainable employability (SE) generally refers to employees’ capacities to function in work and on the labor market throughout their working lives. However, several definitions have been forwarded in the scientific literature that differ in nuanced ways. A recent overview of existing definitions is provided by Fleuren, de Grip, Jansen, Kant, and Zijlstra (2020).[1]

Modelling, Measuring, Visualising Community Resilience
       The concept of community resilience receives much attention in studies and applications due to its ability to provide preparedness against hazards, to protect our life against risks, and to recover to stable living conditions. Nevertheless, community resilience is complex, contextual, multifaceted, and therefore hard to define, recognise, and operationalise. An essential advantage of having a complete process for community resilience is the capacity to be aware of and respond appropriately in times of adversity. A three-step process constituting of modelling, measurement, and visualisation is crucial to determine components, to assess value, and to represent information of community resilience, respectively. The goal of this review is to offer a general overview of multiple perspectives for modelling, measuring, and visualising community resilience derived from related and emerging studies, projects, and tools. By engaging throughout the entire process, which involves three sequential steps as we mentioned above, communities can discover important components of resilience, optimise available local and natural resources, and mitigate the impact of impairments effectively and efficiently.
