Caught in the fire: An accidental ethnography of discomfort in researching sex work

open access: yesFeminist Anthropology, EarlyView.
Abstract Drawing on fifteen years of engagement with researching Israel's sex industry, this article uses accidental ethnography to propose discomfort‐as‐method for feminist anthropology. I argue that discomfort is not a by‐product of fieldwork but a constitutive condition that disciplines researchers and shapes what can be known.

Forecasting Count Data With Varying Dispersion: A Latent‐Variable Approach

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Count data, such as product sales and disease case counts, are common in business forecasting and many areas of science. Although the Poisson distribution is the best known model for such data, its use is severely limited by its assumption that the dispersion is a fixed function of the mean, which rarely holds in real‐world scenarios.

Quadratic Hedging of American Options Under GARCH Models

open access: yesJournal of Futures Markets, EarlyView.
ABSTRACT American options are widely traded in financial markets, yet there is a scarcity of literature on hedging in incomplete markets. In this paper, we derive optimal hedging ratios and option values using Local Risk Minimization (LRM) and Global Risk Minimization (GRM) hedging strategies through dynamic programming.

Cost Analysis Insights for Offshore CCS Hubs: A Case Study of the Santos Basin, Brazil

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT The reuse of decommissioned offshore platforms for geological carbon storage offers a cost‐effective and technically feasible strategy to reduce greenhouse gas emissions in emerging economies. This study presents a comprehensive techno‐economic assessment of offshore carbon capture and storage (CCS) hubs in Brazil, with a focus on the Merluza ...

Diffeomorphic flows driven by Levy processes

open access: yes, 2000
We prove that the stochastic differential equation $$ Y_{s,t}(x) = Y_{s,s}(x) + \int_0^{t-s} f(Y_{s,s+u}(x)) dX_{s+u}, Y_{s,s}(x)=x\in\R^d. $$ driven by a L vy process whose paths have finite p-variation almost surely for some $p\in[1,2)$ defines a flow of locally C^1-diffeomorphisms provided the vector field f is $ $-Lipschitz for some $ >p ...

Medicare Part D and Hospital Admissions due to Antimicrobial Resistance

open access: yesHealth Economics, EarlyView.
ABSTRACT Antimicrobial resistance (AMR) has been increasing rapidly in the United States despite government efforts to contain its spread. Both under‐utilization and overuse of prescribed antimicrobials contribute to rising resistance. The introduction of Medicare Part D in 2006 expanded prescription drug coverage for the elderly, including coverage ...

The Role of AI in Performance Appraisal: A Mixed‐Method Study of Employee Experience Through a Relational Lens

open access: yesHuman Resource Management, EarlyView.
ABSTRACT As artificial intelligence (AI) becomes more common in human resource management (HRM), especially in performance appraisals, questions arise about how employees respond to AI involvement in these processes. While existing research often treats AI as a technical tool, this study also views AI as a social actor that interacts with employees ...

Fock Space Decomposition of Levy Processes

open access: yes, 2003
We show that the general L vy process can be embedded in a suitable Fock space, classified by cocycles of the real line regarded as a group, ${\bf R}$. The formula of de Finetti corresponds to coboundaries. Kolmogorov's processes correspond to cocycles of which the derivatives are cocycles of the Lie algebra of ${\bf R}$.

Embracing Complexity in HRM Research: A Call for System and Process Perspectives

open access: yesHuman Resource Management, EarlyView.
ABSTRACT Human resource management (HRM) is inherently complex. It involves systems of principles, practices, and activities operating at individual, group, organizational, and macro levels, which are interlinked through complex processes. Yet, empirical research has not kept pace with this conceptual richness.

(How) Can Performance Appraisals Improve Employee Creativity? A Multidimensional Perspective

open access: yesHuman Resource Management, EarlyView.
ABSTRACT Performance appraisal (PA) is commonly used by organizations to manage their employees. However, the role of PAs in employee creativity remains ambiguous, with positive, negative, or even nonsignificant relationships reported in the literature. The aim of the present research is to address this ambiguity.
