Over the centuries, from Edward Jenner to Bill Gates, as our scientific
understanding of diseases has increased, so has the focus on prioritizing
new vaccines to help achieve better health. Despite the expanding interest
in and support toward improving global health, constraints inherent to
vaccine development and delivery present decision makers with difficult
choices. Given the lack of effective tools and models to assist the decisionmaking
process, renewed attention is needed to improve the approaches
available for priority setting and for guiding investment decisions....
One of the key features that enables the Greenplum Database to scale linearly and achieve such high performance is its
ability to utilize the full local disk I/O bandwidth of each system. Typical configurations can achieve from 1 to more than
2.5 gigabytes per second sustained I/O bandwidth per machine. This rate is entirely scalable, and overall I/O bandwidth
can be increased linearly by simply adding nodes without any concerns of saturating a SAN/shared-storage backplane.

This report provides a long-term assessment of and outlook for nuclear physics. The first
phase of the report articulates the scientific rationale and objectives of the field, while the second
phase provides a global context for the field and its long-term priorities and proposes a
framework for progress through 2020 and beyond. The full statement of task for the committee is
in Appendix A.
In order to accommodate this kind of diversity, it
is important that project cycle management systems
support the application of standard working
modalities/rules in a flexible manner.
Relationship between projects, programmes and
policies: A well-formulated project should derive
from an appropriate balance between the EC’s
development policy priorities and the partner’s
Within the scope of these policy priorities, the
executive arms of government or non-governmental
agencies formulate the broad areas of work required
to implement policy decisions.
Even a well-resourced, well-designed evaluation study is
unlikely to be able to address all of the above thematic
areas. Deciding what to monitor should be demand-driven,
informed by the target audience and evaluation objectives
as well as the thematic priorities of an organization.
Similarly, the characteristics of a project or programme
(such as type of intervention, scale, stage) and feasibility
issues (such as institutional capacity, financial and
human resources and time) are important considerations.
Australia must significantly scale up its
prevention effort in these and other areas.
Making healthy choices is often difficult – and
there are many barriers to action at all levels.
The Strategy provides a number of priorities and
actions that will help reduce these barriers and
enable healthy choices to become easier. In
the first instance, these actions will help people
maintain or achieve a healthy weight, prevent
smoking and exposure to tobacco smoke, and
limit intake of alcohol to safe levels.
As previously mentioned, preferred stocks are junior to the debt obligations of
the company and senior to common equity. Figure 3 shows the priority of various
security types in a typical capital structure. In this graph we scaled the order of priority
by the average proportion of each security type for financial and non-financial firms in
the S&P 500, in order to highlight not only the priority but also the different relative
importance of each security type for financial versus non-financial firms. When a firm
is liquidated, debt holders are paid first. If debt holders are...
Economic growth in India has picked up in recent years, and like other integrating Asian economies, it
too requires large amounts of efficiently intermediated capital to sustain its development. However, an
important constraint to financial reform has been dealing with the vestiges of financial “repression”—
deliberate policies that crowd out the private sector from credit markets and limit the ability of financial
markets to develop as intermediaries for saving.
As described above, Somalia faces multiple challenges - not least conflict, drought, flooding,
inadequate and inequitable social and public services and massive population displacement - but
persistently high levels of malnutrition are undermining the survival, growth and development of
the population. Rates of acute and chronic malnutrition have consistently exceeded emergency
thresholds in some areas for more than 10 years now.
As the global community continues to scale up health interventions for HIV/AIDS, tuberculosis (TB),
malaria, and other priority areas, it is essential to understand the state of the health systems in which
these services are being delivered. Good health systems should deliver effective, safe, quality health
services to those in need with as much efficiency as possible within local country settings.
Strengthening Uganda‟s health system requires an understanding of its unique strengths and weaknesses.
Market Analysis and Development refers to the development of economically viable and sustainable produc t processing and marketing opportunities for rural areas. In the Comprehensive Poverty Reduction and Growth Strategy (CPRGS) the Government currently attaches high priority to the introduction of good business models and small-scale enterprise opportunitie s for poor households in rural areas.
