This broad geographical distribution, and the wide vertical range, in combination with the high level of specialisation, makes this group a perspective study object to learn about biogeographical and ecological aspects of reducing communities.
This requires methods that can be used without high levels of specialisation and, in turn, allows individuals to gain deep knowledge of particular geographic areas.
Double reading can be broadly divided into three categories: (1) both primary and secondary reading by radiologists of the same degree of sub-specialisation, in consensus, or serially with or without knowledge of the contents of the first report; (2) secondary reading by a radiologist of a higher level of sub-specialisation; (3) double reading of resident reports [5].
To reach a high level of performance, early specialisation typically requires abundant coach-led, 'deliberate practice', designed to improve an athlete's performance through frequent repetitions, use of instructions and frequent corrections, leading to movement reproduction [1, 4].
The high level of host plant specialisation is the result of the enormous variation in plant structure and biochemistry [2] and driven by associated variation in insect herbivore performance among plant species [3].
The findings suggest that students aspire to make a long-term contribution to the profession and there is a high level of interest in specialisation with a desire to achieve financial stability and quality of life.
The Orchidaceae is probably the largest family of flowering plants with more than 27,000 species (Zotz 2013) and is the most diverse plant group (Swarts and Dixon 2009), with high levels of ecological specialisation for pollinators and mycorrhizal fungi (Bailarote et al. 2012).
The transition from traditional to modern society is accompanied by rapid increases in knowledge and high levels of occupational specialisation.
The high levels of achieved specialisation achieved led to an increase in the mix of patients coming outside the sphere of competence of the Local Health Authority (currently 50% of the users).
