Dollars and Domestic Duties: A 22‐Year Study of Income, Home Labor, and Gendered Career Outcomes in Dual‐Earner Couples

Journal of Organizational Behavior, EarlyView.
ABSTRACT Although women's outsized share of household labor and subsequent career disadvantages are well‐documented, the impact of income arrangements within dual‐earner couples has been underexplored in the context of the work–family dynamic. Drawing upon resource and gender construction theories, we examine how income dynamics within male–female ...

When Super (Wo)man Fails to Appear: Beyond Idealized Prototypes in Crisis Leadership

Journal of Organizational Behavior, EarlyView.
ABSTRACT Crisis leadership has been a topic of interest for nearly a century. Recent works present an idealized, gendered template for such leadership by casting men as masculine protectors or superheroes and women as feminine nurturers or selfless, relational superwomen.

Adaptive optimistic concurrency control for heterogeneous workloads

Proceedings of the VLDB Endowment, 2019
Optimistic concurrency control (OCC) protocols validate whether a transaction has conflicts with other concurrent transactions after this transaction completes its execution. In this work, we demonstrate that the validation phase has a great influence on the performance of modern in-memory database systems, especially under heterogeneous workloads. The

FPGA-Accelerated Optimistic Concurrency Control for Transactional Memory

Proceedings of the 52nd Annual IEEE/ACM International Symposium on Microarchitecture, 2019
Transactional Memory (TM) has been considered as a promising alternative to existing synchronization operations, which are often the largest stumbling block to unleashing parallelism of applications. Efficient implementations of TM, however, are challenging due to the tension between lowering performance overhead and avoiding unnecessary aborts.

On optimistic concurrency control for RTDBS

Proceedings of IEEE TENCON '98. IEEE Region 10 International Conference on Global Connectivity in Energy, Computer, Communication and Control (Cat. No.98CH36229), 2002
Real-time database systems (RTDBSs) associate the concept of deadlines with transaction executions. To preserve data integrity, a RTDBS requires concurrency control protocols to synchronise transactions to access shared data. Thus, the goal of scheduling in RTDBSs is twofold: to meet timing constraints (deadlines) of the transactions and to enforce ...

XML Optimistic Concurrency Control Protocol for DOM API

2014 Sixth International Symposium on Parallel Architectures, Algorithms and Programming, 2014
XML concurrency control protocol ensures that transactions execute atomically in a XML database system. Existing concurrency control methods for XML are mainly based on locking. In this paper, we propose two optimistic concurrency control protocols for XML that use snapshot-based approach.

An Efficient Real-Time Optimistic Concurrency Control Protocol

, 1996
In this paper, a new real-time optimistic concurrency control protocol, called OCC-DA, is proposed in which the number of transaction restarts is minimized by dynamically adjusting the serialization order of the conflicting transactions. Unlike other implementations of dynamic serialization order adjustment for optimistic schemes, it is no need to ...

Optimistic similarity-based real-time concurrency control

Proceedings. Fourth IEEE Real-Time Technology and Applications Symposium (Cat. No.98TB100245), 2002
Serializability is unnecessarily strict for real-time systems because most transactions in such systems occur periodically and changes among data values over a few consecutive periods are often insignificant. Hence, data values produced within a short interval can be treated as "similar" and interchangeable.
