Motor sequence learning is considered the result of the outflow of information following cognitive control processes that are shared by other goal-directed behaviours. Emerging evidence suggests that focused-attention meditation (FAM) establishes states of enhanced cognitive control, that then exert top-down control biases in subsequent unrelated tasks. With respect to sequence learning, a single-session of FAM has been shown to entrain stimulus-dependent forms of sequential behaviour in meditation naïve individuals. In the present experiment, we compared single-session effects of FAM and a computerised attention task (CAT) to test if FAM-induced enhanced top-down control is generally comparable to cognitive tasks that require focused attention. We also investigated if effort, arousal or pleasure associated with FAM, or CAT explained the influence of these tasks on sequence learning. Relative to a rest-only control condition, both FAM and CAT resulted in shorter reaction time (RT) in a serial reaction time task (SRTT), and this enhanced RT performance was associated with higher reliance on stimulus-based planning as opposed to sequence representation formation. However, following FAM, a greater rate of improvement in RT performance was observed in comparison to both CAT and control conditions. Neither effort, arousal nor pleasure associated with FAM or CAT explained SRTT performance. These findings were interpreted to suggest that the effect of FAM states on increased top-down control during sequence learning is based on the focused attention control feature of this meditation. FAM states might be associated with enhanced cognitive control to promote the development of more efficient stimulus-response processing in comparison to states induced by other attentional tasks.
Население Маврикия имеет самую высокую продолжительность жизни в Африке. Тем не менее, диабет, ишемическая болезнь сердца, инсульт, грипп и пневмония, а также рак легких, молочной железы и прямой кишки противодействуют успеху здравоохранения в стране. Мужчины, в отличие от женщин, отягощены этими заболеваниями. В исследовании оценивался вклад возраста и смертности от конкретных причин в разрыв в ожидаемой продолжительности жизни среди мужчин и женщин на Маврикии в период с 2005 по 2015 годы. Роль возраста и смертности от конкретных причин и ожидаемой продолжительности жизни среди мужчин и женщин на Маврикии была разложена с использованием подход разложения Андреева. Исследование показало, что зарегистрированные показатели смертности от диабета, ишемической болезни сердца, инсульта, гриппа и пневмонии были выше среди мужчин, чем среди женщин. Мероприятия по укреплению здоровья необходимо будет масштабировать для устранения этих причин смерти, особенно среди мужчин, для достижения национальных и международных целей в области здравоохранения
Cognitive control processes influence how motor sequence information is utilised and represented. Since cognitive control processes are shared amongst goal-oriented tasks, motor sequence learning and performance might be influenced by preceding cognitive tasks such as focused- attention meditation (FAM). Prior to a serial reaction time task (SRTT), participants completed either a single-session of FAM, a single-session of FAM followed by delay (FAM+) or no meditation (CONTROL). Relative to CONTROL, FAM benefitted performance in early, random-ordered blocks. However, across subsequent sequence learning blocks, FAM+ supported the highest levels of performance improvement resulting in superior performance at the end of the SRTT. Performance following FAM+ demonstrated greater reliance on embedded sequence structures than FAM. These findings illustrate that increased top-down control immediately after FAM biases the implementation of stimulus-based planning. Introduction of a delay following FAM relaxes top-down control allowing for implementation of response-based planning resulting in sequence learning benefits.

The author considers the potential ways in which modern technologies can be used in education. The potential benefits of such technologies are particularly promising for rural schools. The article comments on the modern trend to create a seamless educational environment on the basis of e-learning.
Organizations use enterprise architecture (EA), which describes an enterprise from an integrated business and IT perspective, to improve business and IT alignment. The literature describes many different methodologies to organize EA practice. However, organizations typically adapt these EA methodologies to their specific needs rather than use them directly “out of the box”. As a result, actual EA practices often differ substantially from the original EA methodologies. Unsurprisingly, establishing a successful EA practice remains troublesome even though multiple detailed methodologies exist. However, researchers have yet to investigate the adaptation of EA methodologies in organizations. In this paper, based on an in-depth qualitative case study, I explore the adaptation of the most popular EA methodology, TOGAF, to address this gap. In this paper, I holistically describe a TOGAF-based EA practice and analyze the adaptation of the TOGAF methodology in an organization. From my findings, I conclude that none of the TOGAF-specific recommendations proved useful in the studied EA practice. Supported by ample indirect evidence available in the existing EA literature, this study questions the value of TOGAF as a standard for EA practice. Moreover, the studied EA practice hardly resembles any established EA methodologies or theoretical conceptualizations. Therefore, the EA practice that this case study describes presents a new, largely unexplored empirical phenomenon. Although this study raises multiple “inconvenient” questions challenging the status quo in the EA discipline, it does not provide definite answers to most of these questions, which calls for further research on methodological aspects of EA practice.
