to arms. MDG proponents such as McArthur and Sachs countered that setting goals is still valid despite measurement difficulties, as they provide a political and operational framework to efforts. With an increase in the quantity and quality of healthcare systems in developing countries, more data could be collected. They asserted that non-health related MDGs were often well measured, and that not all MDGs were made moot by lack of data. The attention to well being other than income helps bring funding to achieving MDGs. Further MDGs prioritize interventions, establish obtainable objectives with useful measurements of progress despite measurement issues and increased the developed world's involvement in worldwide poverty reduction. MDGs include gender and reproductive rights, environmental sustainability, and spread of technology. Prioritizing interventions helps developing countries with limited resources make decisions about allocating their resources. MDGs also strengthen the commitment of developed countries and encourage aid and information sharing. The global commitment to the goals likely increases the likelihood of their success. They note that MDGs are the most broadly supported poverty reduction targets in world history. Achieving the MDGs does not depend on economic growth alone. In the case of MDG 4, developing countries such as Bangladesh have shown that it is possible to reduce child mortality with only modest growth with inexpensive yet effective interventions, such as measles immunization. Still, government expenditure in many countries is not enough to meet the agreed spending targets. Research on health systems suggests that a "one size fits all" model will not sufficiently respond to the individual healthcare profiles of developing countries; however, the study found a common set of constraints in scaling up international health, including the lack of absorptive capacity, weak health systems, human resource limitations, and high costs. The study argued that the emphasis on coverage obscures the measures required for expanding health care. These measures include political, organizational, and functional dimensions of scaling up, and the need to nurture local organizations. Fundamental issues such as gender, the divide between the humanitarian and development agendas and economic growth will determine whether or not the MDGs are achieved, according to researchers at the Overseas Development Institute (ODI). The International Health Partnership (IHP+) aimed to accelerate MDG progress by applying international principles for effective aid and development in the health sector. In developing countries, significant funding for health came from external sources requiring governments to coordinate with international development partners. As
