Future warming enhances rates of population increase of arthropod crop pests globally
Ecography, EarlyView.Arthropod herbivores cause severe crop yield losses worldwide. Global warming is expected to shift their ranges, phenologies and performances, highlighting the need for improved forecasts of their potential expansion and impacts on food security. After decades of experimental research on thermal biology of arthropod crop pests, available data and tools

Environmental Policy and Governance, EarlyView.ABSTRACT Thailand has announced ambitious plans to reduce greenhouse gas emissions, including a programme that allows private companies to earn carbon credits from protecting and restoring mangroves. In 2023, the Department of Marine and Coastal Resources (DMCR) began enrolling local communities and private firms in this scheme.

Some Dynamic Inequalities of Hilbert’s Type
Journal of Function Spaces, 2020 This paper is concerned with deriving some new dynamic Hilbert-type inequalities on time scales. The basic idea in proving the results is using some algebraic inequalities, Hölder’s inequality and Jensen’s inequality, on time scales. As a special case of

A New Implementation of Network GARCH Model for Stock Volatility and Co‐Volatility Forecasting
Journal of Forecasting, EarlyView.ABSTRACT Volatility clustering and spillovers are key features of financial time series with many cross‐sectional assets. While network analysis links similar or correlated stocks and helps trace volatility spillovers, contemporary multivariate ARCH‐GARCH formulations struggle to represent structured network dependence and remain parsimonious.

Loss‐Aware Forecast Construction for Realized Variance
Journal of Forecasting, EarlyView.ABSTRACT Forecasts of realized variance are commonly constructed from models of log‐realized variance and then transformed back to the original scale. However, the resulting forecasts are often evaluated using loss functions defined in relative rather than absolute terms, creating a potential mismatch between forecast construction and forecast ...

Shape of Yield Curves Under Instrument‐Based Parallel Shifts
Journal of Futures Markets, EarlyView.ABSTRACT This paper studies the shape of zero and par yield curves through the carry and convexity of zero‐bond and par–swap butterflies under instrument‐based parallel shifts: the component instruments are held fixed, and each instrument's own quote receives the same additive shock.

Some complementary inequalities to Jensen’s operator inequality
Journal of Inequalities and Applications, 2018 In this paper, we study some complementary inequalities to Jensen’s inequality for self-adjoint operators, unital positive linear mappings, and real valued twice differentiable functions.

Global Strategy Journal, EarlyView.Abstract Research Summary This article develops a conceptual framework for understanding multinational enterprise (MNE) resilience in the era of cascading crises. We define resilience as the MNE's capacity to absorb disruption, maintain or restore functioning, and reconfigure operations as conditions shift.
