    The Role of Securities Regulation in the Development of the Thai Stock Market

    No full text
    Capital markets have the potential to be powerful engines of economic growth in developing nations. An efficient stock market provides the public with investment opportunities and mobilizes their savings, as well as international capital, for productive corporate financing. Market forces serve to discipline management and public ownership improves the accountability of the business sector. But developing a robust and efficient capital market is a difficult task for many emerging economies. One of the many challenges they encounter is creating an effective securities regulatory regime. In a mature capital market, securities regulations form the framework within which the market operates. They are designed to protect the investor, prevent systemic crises and promote the market they govern. But in what capacity do securities regulations operate in smaller, developing capital markets? The purpose of this paper is to analyze the role of securities regulation in the development of the Thai stock market. The first half of this paper provides some basic background information on the Thai legal system, stock market and economy, and then offers an analysis of the role of securities regulations in the 1997 financial crisis and subsequent process of recovery. The second half addresses the future of securities regulation in Thailand. It begins with an examination of the obstacles that face effective oversight by securities regulators and the regulators' efforts to overcome these obstacles. The paper concludes with an evaluation of the current reform initiative and a proposal for an alternative strategy. In short, this paper seeks to analyze the role that securities regulation has played, will likely play and could play in the development of the Thai stock market

    The Duty to Make Contracts Understandable

    No full text
    So what if consumers can’t understand contracts? They don’t read contracts. They can’t negotiate contracts. All their contracts have the same unfair terms. And nowadays businesses use algorithms, artificial intelligence, and social scientists to craft individualized contracts that hack consumer’s minds. Choice is an illusion. Consumer understanding is a pipedream. Even so, contracts should still be understandable. The opportunity to understand a contract is essential to contract formation’s integrity. While much contract literature focuses on how nonnegotiable contracts cause consumers to make bad deals, this Article challenges the concession that a deal has been made. Contract formation requires consumers have an opportunity to read the contract, which in turn requires consumers have an opportunity to understand what they read. Even if consumers do not exercise this opportunity, and even if exercising that opportunity only reveals how unfair the contract is, this opportunity must exist. The Article proposes that the Uniform Law Commission pass a statute requiring consumer contracts to be understandable to the average intended consumer. Such a law benefits sellers and consumers alike, removes the biggest and oldest impediment to contract innovation (lawyers), incentivizes using machines and science to improve contracts, and might just save transactional lawyers from having their jobs poached by technology

    Reparative Entrepreneurship

    No full text
    Cannabis social equity programs are sub-policies within a larger state marijuana regulatory scheme that are geared towards prioritizing War on Drugs survivors when allocating market space and cannabis sales revenue. Of the over 20 states that have legalized recreational marijuana, many include some version of a cannabis social equity program. The idea of repairing past harm through cannabis entrepreneurship gives a sense of “reparations-ish” policymaking. Through a case study of both the intent and implementation of New York’s Social and Economic Equity (SEE) Plan, this Article examines whether the ideological crux of these programs, the belief that entrepreneurship leads to positive economic outcomes for individuals and communities, can fix decades of discriminatory drug policy rooted in systemic racism. Ultimately, the Article argues that these cannabis social equity programs are more likely to sustain barriers to entry, especially for Black entrepreneurs, whether legal, systemic or political. In this moment of reckoning for the War on Drugs, policies must course-correct and experiment with a new concept of “reparative entrepreneurship.” If the reparations framework advanced in this Article were used, the remedies would be more effective in utilizing entrepreneurship to address the harm of the War on Drugs

    Existing studies have defined and assessed (a) disciplinary literacy, (b) mathematical literacy, and (c) general academic language. However, there is a need to define and assess teachers’ use of mathematics’ discipline-specific language (MDL), particularly elementary school teachers’ use of MDL. The purpose of this study was twofold. First, I defined MDL, developed an instrument to measure it, and tested it with a specific population. Second, after validating the instrument, I used it to analyze the characteristics of teachers’ use of MDL. This analysis was based on data collected from a sample of pre-service elementary teachers who were enrolled in the same special education graduate program. The iterative development of the instrument resulted in an MDL scale (MDLS) that included 20 items rated on a 4-point Likert-like scale distributed between three distinct MDL categories: technical language, symbolic language, and visual language. Validity of the MDLS was confirmed using the set of 211 video recordings and corresponding lesson plans of mathematics lessons taught by pre-service special education elementary teachers. This research led to a modified MDL framework that indicated five distinct factors: technical language precision/explicitness, technical language fluency, symbolic language, visual language precision, and visual language fluency. Results highlighted varying levels of MDL use among elementary school teachers, with symbolic language use being particularly limited

    Measurement of the associated production of a top-antitop-quark pair and a Higgs boson decaying into a ̄ pair in collisions at √ = 13 TeV using the ATLAS detector at the LHC

    This paper reports the measurement of Higgs boson production in association with a ̄ pair in the → ̄ decay channel. The analysis uses 140 fb⁻¹ of 13 TeV proton–proton collision data collected with the ATLAS detector at the Large Hadron Collider. The final states with one or two electrons or muons are employed. An excess of events over the expected background is found with an observed (expected) significance of 4.6 (5.4) standard deviations. The ̄ cross-section is _̄ = 411⁺¹⁰¹₋₉₂fb = 411±54(stat.)⁺⁸⁵₋₇₅(syst.) fb for a Higgs boson mass of 125.09 GeV, consistent with the prediction of the Standard Model of 507⁺³⁵₋₅₀ fb. The cross-section is also measured differentially in bins of the Higgs boson transverse momentum within the simplified template cross-section framework

    Implementing Culturally Sustaining Pedagogies In Chemistry Using Linguistic Tools

    No full text
    Education gaps have been observed in various populations due to instruction in New York schools reflecting a Western, White middle-class perspective. Diversity in schools has been increasing rapidly, and to better serve the changing student population, instruction should be adjusted to reflect their environments and backgrounds so students can reflect, relate, and connect what they learn. In current school systems in New York, and especially New York City Public Schools, addressing the needs of students of color is gravely lacking. Students from diverse backgrounds and cultures need ways to make connections as student diversity increases in schools nationwide. Making these connections can be accomplished using linguistic tools such as student-generated reflections and analogies in science classrooms. This study, set in a public school in the Bronx, uses critical ethnography to observe culturally sustaining pedagogies in chemistry, emphasizing the need to utilize these methods in science education. Two teachers and one co-teacher, along with the students in their classes, were observed as part of the study in which culturally sustaining pedagogies were implemented through designed lessons. The methods students used and the understandings that resulted from them were investigated. A qualitative approach was taken, and data were collected through surveys, observations, interviews, and reflections. I coded the data to find common themes, highlighting how chemistry concepts could be applied beyond the classroom and benefit the communities and environment in which students live. The findings of the study show that students were better able to connect with their backgrounds and identities when culturally sustaining pedagogy lessons were implemented by teachers. The lessons implemented also show students being able to connect to their communities and environment. The use of linguistic tools such as reflections and analogies as a method to show understandings of culturally sustaining pedagogies was shown to be beneficial to student learning. This approach could transform methods of learning chemistry by connecting to students identity and background using linguistic tools. It may also empower students to advocate for their local communities and create positive change as real-world applications of the study. Keywords: culturally sustaining pedagogies, chemistry, reflections, analogies, climate actio

    Since the birth of our nation, scientific discoveries and technological innovations have improved our citizens’ health and well-being and made our country great, yet President Trump is now crippling these engines of American welfare, progress, and power. His proposed cuts to federal research funding and attacks on universities imperil the longstanding global leadership of the United States in scientific and medical discoveries and raise profound bioethical concerns

    The Work of Legitimacy

    No full text
    What makes a law or regulation legitimate? This article develops a sociological approach that locates legitimacy not outside the law but in the work performed by a network of actors that cuts across the boundaries of the state. Drawing on Weber, Habermas, and Szelenyi, we suggest that legitimacy should be understood as the element that increases the probability of compliance with legal commands. We argue that this element cannot be a psychological “belief in legitimacy” but should be understood as work performed by the staff to construct and repair the discursive mechanisms that make legal commands defensible. We then draw on Actor-Network Theory to analyze this work as translation and offer two empirical examples: labor legislation in China and vaccine mandates in the United States. Throughout, we compare our approach with different lines of research in the law and society literature, noting where our conclusions converge and where they represent potential revisions to this literature. Keywords: legitimacy, legal expertise, Actor-Network Theory, complianc

    A Qualitative Exploration of Empathic Forms of Leadership and the Role of Learning from Experience

    No full text
    This dissertation explored how leaders apply and develop empathic leadership styles through experiential learning, emotional intelligence, and reflective practice. This was a response to the growing organizational demand for leadership that fosters trust, inclusion, and adaptability in dynamic environments. The study was guided by three research questions: 1. How do leaders perceive their own leadership styles compared to how their followers perceive them? 2. How do leaders interpret and respond to feedback from followers? 3. How do leaders learn to integrate empathy into their leadership over time? A qualitative multiple-case study design was employed, focusing on 12 organizational leaders and their teams. Data sources included leadership style prediction sheets, Inventory of Leadership Styles (ILS) assessments, and semi-structured interviews. Leaders were categorized into High Performers (HPs) and Other Performers (OPs) to compare developmental patterns. Triangulated data analysis was conducted through inductive coding, thematic synthesis, and cross-case comparisons. Findings revealed that HPs consistently aligned their self-assessments with follower ratings; favored resonant leadership styles (visionary, coaching, affiliative, participative); and demonstrated greater self-awareness, feedback integration, and emotional responsiveness. In contrast, OPs displayed more inconsistent style alignment; greater reliance on dissonant styles (directive, pacesetting); and less reflective learning. Five recurring leadership dimensions emerged—Feedback Integration, Strategic Decision-Making, Vision and Planning, Emotional Responsiveness, and Learning Adaptability—which differentiated HPs from OPs. The study presents a staged Leadership Development Framework that illustrates how empathic leadership develops through assessment, feedback interpretation, reflective practice, and adaptive application. It also offers practical and theoretical recommendations for leadership development practitioners and scholars. Limitations included the sector-specific focus, modest sample size, and reliance on self-report and perceptual data. Future research is recommended to explore empathic leadership across industries, cultures, and virtual contexts. This research contributes to leadership scholarship by demonstrating that empathy, when combined with reflection and feedback responsiveness, is a key driver of effective and sustainable leadership in contemporary organizations
