The effects of alcohol, task difficulty, and incentives on a drill press simulation were examined. On four nonconsecutive days the subject received four alcohol levels, one level per day. The levels were: 0.00%, 0.03%, 0.06%, and 0.09% blood alcohol concentration (BAC). The drill press simulation task consisted of placing a drill probe alternately between two holes in a metal plate. For every level of alcohol, each subject received eight levels of task difficulty which were varied by changing the hole size and distance between holes. Task difficulty was in units of bits of information ranging from two to nine and was derived from a portion of Welford's (1968) version of Fitts' Law. For every level of task difficulty each subject received two levels of incentive: productivity and accuracy which were enforced by monetary rewards. The subject's response was measured by hits and misses. A Hit was defined as placing the metal drill probe in either of two holes in the top metal plate of the workpiece without touching the plate. A miss was defined as a contact of the probe with the top plate. Except for the effect of alcohol on misses, there were significant main effects of alcohol, task difficulty, and incentive for both hits and misses. There were significant interactions between alcohol and task difficulty for hits, and for incentive and task difficulty for both hits and misses. / M.S.

Целью работы является разработка методического подхода для повышения производительности труда на промышленном предприятии. Особенностью данного подхода является двухэтапная оценка факторов производительности труда – проведение качественного анализа трудноизмеримых факторов через опрос сотрудников и корреляционно-регрессионного анализа, что позволяет выработать эффективные предложения по повышению производительности труда на предприятии. / The purpose of the work is to develop a methodical approach to increasing labor productivity at an industrial enterprise. A special feature of this approach is a two-stage assessment of labor productivity factors – conducting a qualitative analysis of hard-to-measure factors through a survey of employees and correlation and regression analysis, which allows us to develop effective proposals for increasing labor productivity at the enterprise.

Even with advanced technology and new project management methodologies, construction company leaders continue to face challenges to improve labor productivity. This multiple case study was an exploration of the strategies that construction company leaders use to improve labor productivity in Doha, Qatar. The case population consisted of 6 construction company leaders operating in Doha, Qatar, who successfully identified and implemented strategies to improve labor productivity. The conceptual framework for this study was the expectancy theory. The data collection process included semistructured interviews and company documentation. Data were compiled and organized, disassembled into fragments, reassembled into a sequence of groups, and interpreted for meaning. Methodological triangulation and member checking bolstered the trustworthiness of those interpretations. Five themes emerged from these 6 construction company leaders: exploring, identifying, and evaluating issues affecting labor productivity; applying an appropriate leadership style; motivating the workforce; providing training and development; and implementing effective project management processes. By improving labor productivity, similar construction companies can complete construction projects faster and with lower construction costs. The implications for positive social change include the potential to lower construction costs and enable individuals with lower incomes in Doha, Qatar, to afford houses that they could not previously afford.

Work sampling had its origin in industrial engineering; however, its use in construction has increased greatly during the 1970's and 1980's. Research would suggest that most of the innovation in this field is taking place in the United States. The basic methods of Work Sampling have been developed to suit the peculiarities of the construction site as opposed to the production line or factory where it was first used. The objectives of this report are as follows: 1. To review the existing methods of Construction Work Sampling as well as discuss further aspects and problems which should be considered when undertaking a Work Sampling study. 2. To compare Construction Work Sampling with other methods of measuring productivity. 3. To evaluate by means of a case study the ease of applicability of the sampling methods to a South African construction site, and at the same time to identify differences between the description of the methods in theory and their use in practice. 4. To establish by means of a questionnaire the extent to which Construction Work Sampling methods are already in use in South Africa as well as other related information. Information for this report was obtained from journals, manuals, text books, interviews, and the case study and questionnaires mentioned.

Оценка факторов производительности труда на региональном уровне является важным аспектом в процессе повышения общего уровня экономического благосостояния территории. Целью магистерской диссертации является развитие теоретико-методических основ анализа и оценки детерминант производительности труда в регионе. В работе рассматриваются теоретические и методические вопросы исследования производительности труда. В качестве источников использовалась научно-исследовательская и учебно-методическая литература, нормативно-правовые акты и статистические данные Федеральной службы государственной статистики по тематике исследования. В магистерской диссертации был предложен методический подход к оценке факторов производительности труда в регионе, особенностью которого является комбинированное использование данных объективных статистических показателей и экспертных мнений, применение статистического инструментария корреляционно-регрессионного анализа, а также реализация аддитивного подхода, предполагающего анализ детерминант производительности труда, рассчитанной различными способами. / Assessment of labor productivity factors at the regional level is an important aspect in the process of increasing the overall level of economic well-being of the territory. The aim of the master's thesis is to develop the theoretical and methodological foundations for the analysis and assessment of the labor productivity determinants of in the region. The paper deals with theoretical and methodological issues in the study of labor productivity. Scientific research and educational-methodical literature, regulatory legal acts, and statistical data of the Federal State Statistics Service on the research topic were used as sources. Master thesis suggest a methodological approach to assessing labor productivity factors in the region, with a feature of the combined use of objective statistical indicators and peer review, application of statistical tools for correlation and regression analysis, and implementation of an additive approach that involves analysis of the determinants of labor productivity, calculated in various ways.
