Empowering women : the effect of women's decision-making power on reproductive health services uptake -- evidence from Pakistan
A large body of research has attempted to explore the links between women's autonomy and their uptake of reproductive health services in the South Asia region, but the evidence so far is inconclusive. This study uses the Pakistan Social and Living Standards Measurement Survey to examine the influence of household decision making on women's uptake of reproductive health services. The analysis finds that women's decision-making power has a significant positive correlation with reproductive health services uptake and that influential males'decision-making power has the opposite effect, after controlling for socio-economic indicators and supply-side conditions. The findings suggest that empowering women and increasing their ability to make decisions may increase their uptake of reproductive health services. They also suggest that policies directed toward improving women's utilization of maternity services must target men as well as women in Pakistan.Health Monitoring&Evaluation,Population Policies,Adolescent Health,Gender and Health,Health Systems Development&Reform
Adaptive Guaranteed-Performance Consensus Control for Multiagent Systems With an Adjustable Convergence Speed
Adaptive guaranteed-performance consensus control problems for multi-agent
systems are investigated, where the adjustable convergence speed is discussed.
This paper firstly proposes a novel adaptive guaranteed-performance consensus
protocol, where the communication weights can be adaptively regulated. By the
state space decomposition method and the stability theory, sufficient
conditions for guaranteed-performance consensus are obtained, as well as the
guaranteed-performance cost. Moreover, since the convergence speed is usually
adjusted by changing the algebraic connectivity in existing works, which
increases the communication burden and the load of the controller, and the
system topology is always given in practical applications, the lower bound of
the convergence coefficient for multi-agent systems with the adaptive
guaranteed-performance consensus protocol is deduced, which is linearly
adjustable approximately by changing the adaptive control gain. Finally,
simulation examples are introduced to demonstrate theoretical results
Projective Truncation Approximation for Equations of Motion of Two-Time Green's Functions
In the equation of motion approach to the two-time Green's functions,
conventional Tyablikov-type truncation of the chain of equations is rather
arbitrary and apt to violate the analytical structure of Green's functions.
Here, we propose a practical way to truncate the equations of motion using
operator projection. The partial projection approximation is introduced to
evaluate the Liouville matrix. It guarantees the causality of Green's
functions, fulfills the time translation invariance and the particle-hole
symmetry, and is easy to implement in a computer. To benchmark this method, we
study the Anderson impurity model using the operator basis at the level of
Lacroix approximation. Improvement over conventional Lacroix approximation is
observed. The distribution of Kondo screening in the energy space is studied
using this method.Comment: 14 pages, 8 figures, published versio
