Genetic advantage and equality of opportunity in education: Two definitions and an empirical application

The literature of Equality of Opportunity (EOp) has long acknowledged the existence of 'talents', 'innate ability' or 'genetic ability'. Nonetheless, attempts to explicitly incorporate a measure of innate ability in the quantification of EOp have been rare. On the other hand, the literature of social-science genetics has found credible genetic-based components of EOp, without an explicit quantification of overall EOp. In addition, there exists prevalent disagreement within both kinds of literature on whether innate ability should be perceived as a fair or unfair source of advantage. This paper proposes to quantify EOp while explicitly including a genetic-based measure of innate ability. It proposes two formal definitions of EOp that draw on both stances regarding the compensation of innate ability. Novel testable implications are derived. The educational attainment polygenic index is used as a measure of innate ability while correcting for genetic nurture and accounting for the correlation between genes and other circumstances. An empirical application in the US Health and Retirement Study finds that the share of inequality of opportunity is 26% under the view that genetic differences are unfair sources of advantage and 21% otherwise. A comparative analysis over cohorts reveals that the trend in EOp depends on the definition adopted; if genetic advantage is a fair source of inequality then EOp has improved; the opposite holds if one considers genetic advantage an unfair source of inequality. These results highlight the importance of accounting for genetic differences in the EOp framework.

Editorial - Animated Space

Since early days, the moving images of animated film have suggested a spatial freedom that challenges the limits of the photographic and traditional filmic space. When, in 1914, Winsor McCay drew himself onto the landscape to interact with Gertie, he was initiating a practice of expanding the space(s) we live in through the use of the animated image that lasts until today. Animation’s wide aesthetic and technical malleability, and its innate ability to suggest metamorphosis and unrest, has led its practice to cross boundaries and engage with the space beyond the limits of the traditional screen.

Comparative transmissibility of SARS-CoV-2 variants Delta and Alpha in New England, USA

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant quickly rose to dominance in mid-2021, displacing other variants, including Alpha. Studies using data from the United Kingdom and India estimated that Delta was 40-80% more transmissible than Alpha, allowing Delta to become the globally dominant variant. However, it was unclear if the ostensible difference in relative transmissibility was due mostly to innate properties of Delta's infectiousness or differences in the study populations. To investigate, we formed a partnership with SARS-CoV-2 genomic surveillance programs from all six New England US states. By comparing logistic growth rates, we found that Delta emerged 37-163% faster than Alpha in early 2021 (37% Massachusetts, 75% New Hampshire, 95% Maine, 98% Rhode Island, 151% Connecticut, and 163% Vermont). We next computed variant-specific effective reproductive numbers and estimated that Delta was 58-120% more transmissible than Alpha across New England (58% New Hampshire, 68% Massachusetts, 76% Connecticut, 85% Rhode Island, 98% Maine, and 120% Vermont). Finally, using RT-PCR data, we estimated that Delta infections generate on average ~6 times more viral RNA copies per mL than Alpha infections. Overall, our evidence indicates that Delta's enhanced transmissibility could be attributed to its innate ability to increase infectiousness, but its epidemiological dynamics may vary depending on the underlying immunity and behavior of distinct populations.

Global Transcriptome Profile of the Oleaginous Yeast Saitozyma podzolica DSM 27192 Cultivated in Glucose and Xylose

Unlike conventional yeasts, several oleaginous yeasts, including Saitozyma podzolica DSM 27192, possess the innate ability to grow and produce biochemicals from plant-derived lignocellulosic components such as hexose and pentose sugars. To elucidate the genetic basis of S. podzolica growth and lipid production on glucose and xylose, we performed comparative temporal transcriptome analysis using RNA-seq method. Approximately 3.4 and 22.2% of the 10,670 expressed genes were differentially (FDR < 0.05, and log2FC > 1.5) expressed under batch and fed batch modes, respectively. Our analysis revealed that a higher number of sugar transporter genes were significantly overrepresented in xylose relative to glucose-grown cultures. Given the low homology between proteins encoded by most of these genes and those of the well-characterised transporters, it is plausible to conclude that S. podzolica possesses a cache of putatively novel sugar transporters. The analysis also suggests that S. podzolica potentially channels carbon flux from xylose via both the non-oxidative pentose phosphate and potentially via the first steps of the Weimberg pathways to yield xylonic acid. However, only the ATP citrate lyase (ACL) gene showed significant upregulation among the essential oleaginous pathway genes under nitrogen limitation in xylose compared to glucose cultivation. Combined, these findings pave the way toward the design of strategies or the engineering of efficient biomass hydrolysate utilization in S. podzolica for the production of various biochemicals.

You have got items to show off your pride: the effects of pride on preference for attention-grabbing products

Purpose This study examines the impact of incidental pride on consumer preference for attention-grabbing products. This effect is mediated by the desire to gain attention. This study also shows that the effect of incidental pride is qualified by visibility of consumption. Design/methodology/approach Using two studies with between-subjects designs, this research examines the difference in preferences for attention-grabbing products between hubristic and authentic pride. Findings Individuals who experience hubristic pride (vs authentic pride) show greater preference for attention-grabbing products and have a strong desire to gain attention from others. However, when consumption is perceived as private (vs public), preferences for attention-grabbing products weaken for those who experience hubristic pride. Research limitations/implications This research studies the effect of incidental pride on consumer preference. By examining dispositional pride effects, future research may expand these findings, which enrich the literature on emotion. Future research can identify the potential mechanism for the relationship between authentic pride and preference for attention-grabbing products in the context of private consumption. Practical implications Marketers and salespersons can guide and recommend products with attention-grabbing features to customers celebrating a friend’s success in recognition of their innate ability. Second, marketers may encourage consumers to buy attention-grabbing products with targeted advertising or emotion-eliciting advertising (i.e., evoke a certain type of pride). Originality/value While prior studies focused on basic emotions, this research has investigated self-conscious emotions that are central to consumer behavior. This research contributes to the understanding of self-conscious emotions that affect consumers’ behavioral responses in unrelated situations. Investigating the two facets of pride, the findings show the impact of pride on the preference for attention-grabbing products and reveals that visibility of consumption moderates the effect of pride.

Fair income tax with endogenous productivities and a fresh start

This paper considers a model in which agents have heterogeneous preferences over labour and consumption. Additionally, they also differ in their earning skills, which are a function of both an innate ability and an early investment decision. In this framework we axiomatically derive a social ordering function that, besides compensating agents for their unequal productivities, grants a fresh start to those who regret their initial choices. Next, by assuming a second-best context we characterise the income tax scheme that satisfies this social ordering. This analysis permits us to present an explicit criterion for the assessment of social welfare under different tax policies. We obtain that the optimal scheme aims to compensate those endowed with the lowest marginal productivity. More importantly, on account of the forgiveness ideal positive social marginal weights are assigned to those who earn the lowest income levels, something that induces a progressivity tendency at the bottom of the earnings distribution.

The Many Applications of Engineered Bacteriophages—An Overview

Since their independent discovery by Frederick Twort in 1915 and Felix d’Herelle in 1917, bacteriophages have captured the attention of scientists for more than a century. They are the most abundant organisms on the planet, often outnumbering their bacterial hosts by tenfold in a given environment, and they constitute a vast reservoir of unexplored genetic information. The increased prevalence of antibiotic resistant pathogens has renewed interest in the use of naturally obtained phages to combat bacterial infections, aka phage therapy. The development of tools to modify phages, genetically or chemically, combined with their structural flexibility, cargo capacity, ease of propagation, and overall safety in humans has opened the door to a myriad of applications. This review article will introduce readers to many of the varied and ingenious ways in which researchers are modifying phages to move them well beyond their innate ability to target and kill bacteria.

A Review on Bacterial Contribution to Lignocellulose Breakdown into Useful Bio-Products

Discovering novel bacterial strains might be the link to unlocking the value in lignocellulosic bio-refinery as we strive to find alternative and cleaner sources of energy. Bacteria display promise in lignocellulolytic breakdown because of their innate ability to adapt and grow under both optimum and extreme conditions. This versatility of bacterial strains is being harnessed, with qualities like adapting to various temperature, aero tolerance, and nutrient availability driving the use of bacteria in bio-refinery studies. Their flexible nature holds exciting promise in biotechnology, but despite recent pointers to a greener edge in the pretreatment of lignocellulose biomass and lignocellulose-driven bioconversion to value-added products, the cost of adoption and subsequent scaling up industrially still pose challenges to their adoption. However, recent studies have seen the use of co-culture, co-digestion, and bioengineering to overcome identified setbacks to using bacterial strains to breakdown lignocellulose into its major polymers and then to useful products ranging from ethanol, enzymes, biodiesel, bioflocculants, and many others. In this review, research on bacteria involved in lignocellulose breakdown is reviewed and summarized to provide background for further research. Future perspectives are explored as bacteria have a role to play in the adoption of greener energy alternatives using lignocellulosic biomass.

On The Corporeality Of Atmosphere

Space is a constant inhabited medium which is inseparable from its role as a lived human environment. Both defined and undefined by concrete matter, it possesses an innate ability to envelop the body in deep spatial experiences. These experiences can be intense, even poetic. This naturally felt presence is a profound relationship between body and surrounding; the vehicle for this experience is atmosphere. Atmosphere is the mode of providing experiential space within architecture, feeding one’s presence in their world; without consideration for atmospheric conditions renounces built form void of these experiences. By conceiving architecture through the embodied experience of atmospheres, space can intrinsically permit the body to experience its surrounding. This work is a continuous exploration of designing architecture through its atmosphere; as such, a focus will be redirected back to a bodily experience by activating the innate relationship between atmosphere and the body.
