Social Impact Bonds: Blockbuster or Flash in a Pan?

Despite the general hype, Social Impact Bonds’ (SIB) rate of adoption is still modest. The mismatch between widespread interest and actual adoption raises interesting questions as to whether we are still in the early adoption phase of SIBs and massive diffusion is yet to come, or we are observing a marginal phenomenon. In order to shed some light on this issue, the paper provides a review of the cases in which the SIB model has been already applied, exploring the specific configuration employed, with the purpose to identify regular configuration patterns and their deviation from a prototypical structure.     

Increasing knowledge of food deserts in Brazil: The contributions of an interactive and digital mosaic produced in the context of an integrated education for sustainability program

As efforts to end hunger, food insecurity and malnutrition evolve within the context of United Nations' Global Compact and Sustainable Development Goals; such problems remain far from being solved due, in part, to their complex nature. Brazil exemplifies such multifaceted scenario as the country has left the “hunger map” in 2014 but now faces another issue: The quality of the food available to its population. Physical, social, economic, cultural, and political factors have impacted the Brazilian food environment, shaping new eating habits such as the replacement of traditional local food for processed foods. Within this context, educational institutions may play an important role in spreading knowledge about major social challenges such as this and their interdependent causes. This paper presents the case study of a project conducted by business and public administration students in a discipline called Integrated Education for Sustainability (FIS), offered to undergraduate students at one of Brazil's most important management schools. In 2017, the project worked on the topic of Food Deserts, challenging the students to develop a digital and interactive mosaic that uncovers the situation of the food deserts in São Paulo. Data were collected from participant observation, field trips, events, and interviews conducted in class with 18 professionals working on several areas related to the topic. The article provides insights into (a) the importance of education to tackle the sustainability challenges, (b) lessons learned from the 14th edition of FIS course, and (c) the several barriers to food access in the city of São Paulo.     

Risk aversion in two-period rent-seeking games

This work analyzes a two-period rent-seeking game, with the aim of studying the effect of risk aversion on the optimal choices made by the rent-seekers. We first prove that the equilibrium in two-period rent-seeking games always is unique. The analysis also shows that more risk aversion reduces the investment in the rent-seeking game in a two-period framework without introducing the additional condition of prudence, required in one-period models. Similarly, the introduction of a risky rent, instead of a given rent, implies, in the two-period framework, a reduction in investment under the condition that the rent-seekers are risk averse. Moreover, with risk aversion, larger first-period wealth increases investment in the rent-seeking game and larger second-period wealth reduces it. When both first-period and second-period wealth increase, investment in the rent-seeking game declines if the rent-seeker is risk averse and imprudent. Lastly, when a risky level of second-period wealth is introduced, the rent-seeker increases (reduces) investment in the rent-seeking game if he is risk averse and prudent (imprudent).

     

THIRD TIME'S A CHARM?

正When we look at the situation right now,in terms of COVID-19 origin investigations,we have a state of affairs that is tainted black by the geopolitical narrative.That narrative first took hold with the Donald Trump administration and today still exudes very strongly from the Joe Biden administration.     

Current trends in nanotechnology research across worldwide geo-economic players

The purpose of this paper is to analyze the current temporal and spatial trajectories in nanotechnology research in order to display the worldwide patterns of scientific domains across main geo-economic players. Current trends of nanotechnology have been growing in chemistry and medicine because of technological applications of new nanomaterials mainly in Chemical Engineering, Biochemistry, Genetics and Molecular Biology. In addition, the results show that the laboratories of Europe and North America have intensive scientific collaborations with foreign scholars in nanotechnology studies. This paper can provide vital findings to support new research and innovation policies in order to foster the development of these driving converging technologies for future patterns of economic growth.     

Camouflaging Facial Emphysema: A new syndrome

Some cosmetic products manufactured in Korea for the treatment of eczema, seborrhea and psoriasis have been suspected to contain anti-inflammatory corticosteroids such as prednisolone, hydrocortisone, betamethasone, dexamethasone and triamcinolone acetonide without these ingredients being indicated on the label. Due to their severe side effects such as permenent skin atopy, these corticosteroids have to be monitored in cosmetic products from a forensic point of view. Many cosmetic product samples (N=65) have been collected from both local and online markets in Korea. The corticosteroid content of these samples was analyzed by LC-MS/MS with diagnostic ions (m/z). Linearity was studied with 0.1-10 μg/mL range in all corticosteroids. Good correlation coefficients (r(2)≥0.997) were found and the limits of quantification were 4.68-7.97 ng/mL for each of the corticosteroids. At three different concentrations spanning the linear dynamic ranges, mean recoveries were 97.2-113.5%and precisions (RSD) for intra-day and inter-day analysis were less than 8.9%. Also, accuracy (Bias %) was less than 11.8%. The results showed that between 0.76-0.94 μg/g levels of prednisolone were detected in four cosmetic products and triamcinolone acetonidewas detected with a concentration in the range of 11.5-272 μg/g in nine samples. This fact reveals that some manufacturers have arbitrarily added these corticosteroids in their cosmetic products without indicating them on the label. Thus, these cosmetic products have to be monitored and if proven illegal preparations removed from the market.     

A comparison of email versus letter threat contacts toward members of the United States Congress

To better understand inappropriate correspondence sent to public officials, 301 letter cases and 99 email cases were randomly selected from the United States Capitol Police investigative case files and compared. Results indicate that letter writers were significantly more likely than emailers to exhibit indicators of serious mental illness (SMI), engage in target dispersion, use multiple methods of contact, and make a problematic approach toward their target. Emailers were significantly more likely than letter writers to focus on government concerns, use obscene language, and display disorganization in their writing. Also, letter writers tended to be significantly older, have more criminal history, and write longer communications. A multivariate model found that disorganization, SMI symptoms, problematic physical approach, and target dispersion significantly differentiated between the correspondence groups. The group differences illuminated by this study reveal that letter writers are engaging in behavior that is higher risk for problematic approach than are emailers.
