Understanding the complex relationship between sleep and memory is one of the biggest challenges in neuroscience. Thousands of studies on memory consolidation suggest that sleep triggers offline memory processes, resulting in less forgetting in declarative memory and performance improvement in non-declarative memory. However, an increasing number of contradictory findings reveal potential issues with how research is conducted in this field, that weaken the reliability of these results. Here we describe four methodological pitfalls with respect to experimental designs and statistical analyses that should be avoided in order to unveil the true effect of sleep on memory consolidation: non-optimal experimental designs, task complexity, fatigue effect in repetitive tasks, and data analysis and availability. We then offer solutions that can be used in future research of sleep-dependent consolidation and also more broadly in memory research.

Understanding the complex relationship between sleep and memory is a major challenge in neuroscience. Thousands of studies on memory consolidation in humans suggest that sleep triggers offline memory processes, resulting in less forgetting of declarative memory and performance stabilization in non-declarative memory. However, an increasing number of contradictory findings reveal potential issues with how research is conducted in this field and call into question the reliability and interpretation of the results. In this consensus paper, we describe four sets of prevalent methodological pitfalls in human sleep and memory research: (i) non-optimal experimental designs, (ii) task complexity, (iii) fatigue effects in repetitive tasks, and (iv) inappropriate data analysis practices. We then offer solutions to each of these pitfalls. We believe that implementing these solutions in future research of sleep and memory will lead to more reliable results and significantly advance our understanding in this field.

Performance appraisal has been the focus of considerable research for almost a century. Yet, this research has resulted in very few specific recommendations about designing and implementing appraisal and performance management systems whose goal is performance improvement. We believe that a reason for this is that appraisal research became too interested in measurement issues and not interested enough in ways to improve performance, although some recent trends in the area have begun moving the field in the right direction. We review these trends and their genesis, and propose a motivational framework as a means of integrating what we have learned and generating proposals for future research that focus on employee's performance improvement.

Abstract Purposes of Review This review highlights the effect of sex differences in sleep mediated memory consolidation and cognitive performance. In addition, the role of menstrual cycle and the fluctuating level of sexual hormones (mainly oestrogen and progesterone) are stressed. Recent Findings The literature indicates that sex hormones mediate and orchestrate the differences observed in performance of females in comparison with males in a variety of tasks and can also be related to how sleep benefits cognition. Although the exact mechanism of such influence is not clear, it most likely involves differential activation of brain areas, sensitivity to neuromodulators (mainly oestrogen), circadian regulation of sleep and temperature, as well as modification of strategies to solve tasks across the menstrual cycle. Summary With the evidence presented here, we hope to encourage researchers to develop appropriate paradigms to study the complex relationship between menstrual cycle, sleep (its regulation, architecture and electrophysiological hallmarks) and performance in memory and other cognitive tasks.

Training is aimed in improving the conduct and performance of workers. Worker commitment is the level of responsibility and association a worker has towards the organization and its qualities. The information required for the examination had been accumulated from both primary and secondary data. Every one of these exercises focus on progress of workers productivity. Convenient sampling is utilized and descriptive exploration is received. The center piece of the investigation lies in the analysis and interpretation. It was discovered that training has positive and critical effect on worker's productivity in Indian Automobile industry. Through this research we can build up a conceptual framework for future research that focuses around workers performance improvement. The research was lead for workers working in automobile industry with respect to effectiveness of the training programs in industries.

This article aims to examine the variable compensation program for performance implanted in the Brazilian Judiciary. For this purpose, a survey was conducted with the servers of the Court of Justice of the State of Roraima - Amazon - Brazil. The strategy consisted of field research with quantitative approach, with descriptive and explanatory research and conducting survey using a structured questionnaire, available through the INTERNET. The population surveyed, 37.79% is the sample. The results indicate the effectiveness of the program as a tool of motivation and performance improvement and also the need for some adjustments and improvements, especially on the perception of equity of the program and the distribution of rewards.
