When is a problem a research problem?

Various definitions of and approaches to research and research problems are explored with numerous examples given. Guiding criteria for applied research are also discussed, along with potential pitfalls, the role of intuition in the process, and the qualities that are needed to make a good researcher.published or submitted for publicatio

Great nature’s second course: Introduction to the special issue on the behavioral neuroscience of sleep

Sleep is necessary for normal psychological functioning, and psychological function in turn affects sleep integrity. Recent investigations delineate the relation of sleep to a broad array of processes ranging from learning and memory to emotional reactivity and mood, and use a variety of methodological approaches (imaging, electrophysiological, behavioral) to reveal the complex relations between sleep and the functioning of the awake brain. The articles in this issue advance our fundamental knowledge of the relation of sleep to psychological function. In addition, several of the articles discuss how sleep is affected by or affects human clinical conditions, including insomnia, epilepsy, mild cognitive impairment, bipolar disorder, and cancer. Together, the articles of this special issue highlight recent progress in understanding the behavioral neuroscience of sleep and identify promising areas for future research, including the possibility of sleep-based interventions to improve psychological health.Accepted manuscrip

Primary electric power generation systems for advanced-technology engines

The advantages of the all electric airplane are discussed. In the all electric airplane the generator is the sole source of electric power; it powers the primary and secondary flight controls, the environmentals, and the landing gear. Five candidates for all electric power systems are discussed and compared. Cost benefits of the all electric airplane are discussed

Emergence of nonmotor symptoms as the focus of research and treatment of Parkinson's disease: Introduction to the special section on nonmotor dysfunctions in Parkinson's disease

Parkinson's disease (PD) is traditionally characterized by the cardinal motor symptoms of tremor, rigidity, slowness of movement, and impairments of posture, gait, and balance. A relatively new focus of research and treatment is the nonmotor symptoms of the disease, following from recent understanding of the neuropathological stages. Disruptions of arousal, mood, sleep, and autonomic function before the first motor signs of PD implicate the lower brainstem, which is affected before the substantia nigra and dopaminergic system. In later stages of the disease, the pathology extends to the cortex, accompanied by impairments in cognition and perception. The articles in this special section advance our knowledge of the brain bases of the nonmotor symptoms of PD, including disrupted visual perception, impaired cognition across a range of domains, and psychiatric and artistic manifestations. Subtypes under investigation include those described by side of disease onset (left or right body side), predominant cognitive profile, and gender. Taken together, the articles in this special section reflect the field's growing focus on the nonmotor symptoms of PD, their brain bases, and the corresponding potential for their treatment.Published versio

Beyond 2015: Maintaining Ireland’s Public Finances on a Sustainable Path

In this note, three mechanical fiscal rules that are designed to maintain a sustainable path for the public finances are examined. Adherence to a strict numerical target for the deficit ratio has a procyclical effect on the economy’s growth rate. Building a safety margin into deficit targets in the manner of the Stability and Growth Pact allows the public finances to have a stabilising influence on the growth cycle and ensures a lower average government debt ratio is achieved over time. A debt target rule would result in a different path for the structural primary budget balance and the debt ratio over time even when the long run targets for those variables were the same as under the Pact.
