Acquired And Useful Abilities: Three Essays On Human Capital Development, Rajan Bishwakarma

Economics ETDs

While early childhood circumstances influence the accumulation of skills and abilities, parental and policy responses can magnify or mitigate the effects of childhood circumstances. This work explores the two ideas mentioned above.

Chapter 1 briefs the historical and philosophical roots of the study of human capital and discusses the economic approach to the understanding of child wellbeing before the age of five. Because childhood circumstances influence the accumulation of skills, Chapter 2 estimates the impact of temperature shock during pregnancy on early childhood health. Evidence from Nepal shows that prenatal exposure to high-temperature days impedes child growth; however, the damage …

The Relationship Between Young Adult Attachment And Loneliness Factors With Their Childhood Social Media Usage Patterns, Kenneth Walter Mark

Doctoral Dissertations and Projects

Social media use has become an integral and often ignored part of children’s lives because it is rationalized not to be detrimental to their future development. However, childhood social media use was associated with insecure attachment styles and possible loneliness issues emerging in young adulthood. Past research examined social media use and secular attachment in the present only, without examining spiritual attachment or loneliness levels. This is the first research study to explore longitudinally the relationship between past childhood social media use and current young adult (aged 18-24) secular attachment, spiritual attachment, and loneliness levels. The population (N = 149) …

Employed Algorithms: A Labor Model Of Corporate Liability For Ai, Mihailis E. Diamantis

Duke Law Journal

The workforce is digitizing. Leading consultancies estimate that algorithmic systems will replace 45 percent of human-held jobs by 2030. One feature that algorithms share with the human employees they are replacing is their capacity to cause harm. Even today, corporate algorithms discriminate against loan applicants, manipulate stock markets, collude over prices, and cause traffic deaths. Ordinarily, corporate employers would be responsible for these injuries, but the rules for assessing corporate liability arose at a time when only humans could act on behalf of corporations. Those rules apply awkwardly, if at all, to silicon. Some corporations have already discovered this legal …

Short-Range Magnetic Correlations, Spontaneous Magnetovolume Effect, And Local Distortion In Magnetic Semiconductor Mnte, Raju Baral

Theses and Dissertations

The antiferromagnetic semiconductor MnTe has recently attracted significant interest as a potential high-performance thermoelectric material. Its promising thermoelectric properties are due in large part to short-range magnetic correlations in the paramagnetic state, which enhance the thermopower through the paramagnon drag effect. Using magnetic pair distribution function (mPDF) analysis of neutron total scattering data, we present a detailed, real-space picture of the short-range magnetic correlation in MnTe, offering a deeper view into the paramagnon drag effect and the nature of the correlated paramagnetic state. We confirm the presence of nanometer-scale antiferromagnetic correlations far into the paramagnetic state, show the evolution of …

As a result, enforcers are starting to equip themselves with sophisticated digital investigation tools. This paper explores this interest in building an Artificial Intelligence (AI) arsenal for the fight against algorithmic infringements. What are the key factors motivating regulators to develop their own technological tools to enforce competition law? Building on interviews with a number of competition authorities, this paper finds that changes in digital markets, the need for enforcers to reverseengineer companies’ algorithms in order to better understand …

Competition Law Enforcement In Ukraine: Challenges From On-Line Giants, Anzhelika Gerasymenko, Nataliia Mazaraki

Yearbook of Antitrust and Regulatory Studies

Competition law, economics and policy are facing a regulatory metamorphosis due to the rise of the digital economy. US, China and EU jurisdictions have announced and partially introduced systemic changes to their competition law frameworks to keep pace with technological developments. The Antimonopoly Committee of Ukraine is following the principle of ‘three monkeys’, it sees no on-line platforms, hears no on-line platforms, speaks of no on-line platforms, so nothing has been undertaken or even announced. The paper is twofold. Firstly, it analyses the economic background and features of the digital economy and shows why the available instruments of competition enforcement …

Section 19a Gwb As The German ‘Lex Gafa’ – Lighthouse Project Or Superfluous National Solo Run?, Tabea Bauermeister

Yearbook of Antitrust and Regulatory Studies

As the European Union kept on struggling with its Digital Markets Act, Germany forged ahead and implemented its own ‘Lex GAFA’ in early 2021. The paper will introduce this new Section 19a and explain its inner workings. Furthermore, Section 19a will be compared to classic Article 102 TFEU-procedure and contrasted with the DMA. Thereby, the paper will present the advantages and disadvantages of Section 19a in comparison to existing and future European law to assess whether Section 19a is in fact the lighthouse project it was presented to be – or rather a superfluous national solo run.

Engineering Order-Disorder Transitions For High-Performance Thermoelectric Fe2val Heusler Alloys, Cory T. Cline

Dartmouth College Ph.D Dissertations

Fe₂VAl shows great promise as an eco-friendly and low-cost replacement to conventional low-temperature (250-500 K) thermoelectric materials. Current thermoelectric materials use toxic and expensive elements like Te and Sb, whereas Fe₂VAl offers a larger power factor at a lower cost and a reduced risk of environmental pollution. The key issue with Fe₂VAl is the alloy’s relatively large thermal conductivity compared to its semiconductor competitors. This thesis aims to investigate a hierarchical approach to reduce lattice thermal conductivity through a preliminary exploration of heavy element substitutions and mechanical deformation, then through probing order-disorder transitions for …

Accumulation Of Sublethal Radiation Damage And Its Effect On Cell Survival, Oleg N Vassiliev

Faculty, Staff and Student Publications

Objective. Determine the extent of sublethal radiation damage (SRD) in a cell population that received a given dose of radiation and the impact of this damage on cell survival. Approach. We developed a novel formalism to account for accumulation of SRD with increasing dose. It is based on a very general formula for cell survival that correctly predicts the basic properties of cell survival curves, such as the transition from the linear-quadratic to a linear dependence at high doses. Using this formalism we analyzed extensive experimental data for photons, protons and heavy ions to evaluate model parameters, quantify the extent …
