Refinements of the integral form of Jensen’s and the Lah–Ribarič inequalities and applications for Csiszár divergence

Journal of Inequalities and Applications, 2020
In this paper, we give refinements of the integral form of Jensen’s inequality and the Lah–Ribarič inequality. Using these results, we obtain a refinement of the Hölder inequality and a refinement of some inequalities for integral power means and ...

Assessing Sustainability Performance in the Life Insurance Industry: An Integrated Sustainability Balanced Scorecard Framework Under q‐Rung Orthopair Fuzzy Information

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Assessing the sustainability performance of life insurers has become increasingly important, as long‐term competitiveness depends not only on financial soundness but also on environmental, social, organizational, and governance‐related capabilities.

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

Addressing Barriers to Fair Community Participation in Mangrove Carbon Credit Projects: Insights From Thailand

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.

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.

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

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.
