Unveiling the Nexus Between Board Gender Diversity, CSR and Financial Performance: Evidence From an Emerging Economy

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the nexus between board gender diversity (BGD), corporate social responsibility (CSR) performance, and financial outcomes in the context of an emerging country, Türkiye. The sample consists of Turkish non‐financial firms listed on Borsa Istanbul for the period 2008–2023.

Extended Non-Binary Low-Density Parity-Check Codes over Erasure Channels

, 2011
Based on the extended binary image of non-binary LDPC codes, we propose a method for generating extra redundant bits, such as to decreases the coding rate of a mother code.

CSR Disclosure and Operating Performance in the Agri‐Food Manufacturing Industry: Evidence From Southern Europe

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores the relationship between corporate social responsibility (CSR) disclosure and operating profitability in the agri‐food manufacturing industry of Southern Europe, focusing on Extremadura (Spain). From an initial pool of 284 firms, the final sample comprised 185 companies after excluding inactive or non‐reporting cases.

Evaluation of a Partial Ban on Rx‐Rebates in Germany

Health Economics, EarlyView.
ABSTRACT We investigate patients' price sensitivity for prescription (Rx) drugs with regards to patronizing online or brick‐and‐mortar pharmacies. In doing so, we exploit a policy change in Germany that prohibited online pharmacies from granting rebates to one part of the population, the members of the statutory health insurance scheme.

Planar Quantum Low-Density Parity-Check Codes with Open Boundaries

PRX Quantum
Although high-threshold and low-overhead quantum low-density parity-check (qLDPC) codes, such as bivariate bicycle (BB) codes, can reduce the physical-qubit cost by an order of magnitude compared to the Kitaev toric code, their torus layout remains ...

Shortened Array Codes of Large Girth

, 2006
One approach to designing structured low-density parity-check (LDPC) codes with large girth is to shorten codes with small girth in such a manner that the deleted columns of the parity-check matrix contain all the variables involved in short cycles. This

Diversifying Environmental, Social and Governance Portfolios: Evidence From China

International Journal of Finance &Economics, EarlyView.
ABSTRACT This study extends traditional portfolio optimization methods by incorporating Environmental, Social and Governance (ESG) performance measures into diversification strategies, specifically focusing on data from the Chinese stock market. By integrating ESG scores and their constituent components (E, S and G), the study examines portfolio ...

Reordered static layered schedule for 5G low‐density parity‐check codes

Electronics Letters
The error performance of the 5G low‐density parity‐check codes is significantly impacted by the update order of layers. At present, the row degree (RD) and the number of punctured bits (PBs) are widely used to decide the update order of layers. Here, the

A construction of the high-rate regular quasi-cyclic LDPC codes

EURASIP Journal on Wireless Communications and Networking, 2019
In this paper, a scheme to construct the high-rate regular quasi-cyclic low-density parity-check (QC-LDPC) codes is developed based on the finite geometry low-density parity-check (LDPC) codes.

Ldpc Code Construction using Randomly Permutated Copies of Parity Check Matrix [PDF]

مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2018
A construction technique is proposed for low-density parity check (LDPC) codes. It uses a base parity check matrix designed from a ran-dom or constructed construction method as Gallager or Quasi-Cyclic LDPC (QC-LDPC) codes in sequence to get codes with ...
