And long-term threats to fiscal health, such as the demands of an ageing population or structural impediments to the economy, can get ignored in the process.In Japan, for instance, attempts to jump-start the economy through heavy deficit-spending have fallen flat.
Other rivers with shortnose sturgeon appear to be slowly developing larger populations or have impediments that can be addressed with more determined species protection measures.
Finally, further research is needed: firstly, to enquire into the protective role of education in this research population, given the impediment of residence status and, secondly, to determine whether (reverse) causation between socio-economic position and health applies and, if so, how much exposure to a setback in socio-economic position suffices to trigger ill-health.
Both the failure of effective public health initiatives to influence public health practice and the lag between evidence generation and implementation represent considerable impediments to population health improvement as it denies or delays community access to effective services [ 3- 5].
And though the strategy identifies Japan's aging, shrinking population as a chief impediment to growth, it suggests few new ways of dealing with it.
Tundra swans are absent in summer as they migrate to the arctic and subarctic to nest, however, the non-native, Eurasian Mute swans compete for habitat with the non-migrating Trumpeter swan population and is an impediment to restoration of the native trumpeters around the Great Lakes.
The main impediment to population recovery was believed to be high anthropogenic mortality [10], [11], [12] and there is a continuous debate as to whether additional transplant augmentations should even proceed.
Misconceptions regarding inheritance and a lack of attention to variation within populations are two potential impediments for students studying natural selection.
For those in the field, the regulatory antiquity and recalcitrance of many physicians to move from a pharmaceutical-based patient-management perspective to a more holistic one that includes recommendations of food and supplement-based products to both general and patient populations remain among the impediments to progress.
The joint effects of poor oral health and chronic diseases are major impediments to overall population health and quality of life, especially among the socioeconomically disadvantaged.
