AbstractThe global digital communications network, colloquially known as the “internet”, has received much attention in recent years from business, media, cultural, and government interests. This paper looks behind the hype and sales-pitches, at the essential features of the medium which have made it (and will continue to make it) the central technology for the dissemination of information in the next century. It is a particularly important technology for remote communities, since all information resources (educational, commercial, and recreational) can be transmitted using a standard set of protocols (Hypertext Transfer Protocol, File Transfer Protocol, Network News Transfer Protocol), over any physical medium (packet radio, satellite, phone-line, and optic fibre), in any data format that can be digitised (radio, television, text, graphics, and sound). The implications of this non-coercive technology are explored in the context of the impact on development in the physically distant communities of the South Pacific.

Agency theory studies the impact of and remedies to asymmetrically distributed information in principal-agent relations. Yet, it does so in a surprisingly binary manner: It assumes the principal to be perfectly knowledgeable of some pieces of information (such as the agent’s risk aversion), while others (such as the agent’s true effort exerted) are considered to be perfectly private information of the agent. Agency theory thus makes highly asymmetrical assumptions about the knowledge of principals and agents, largely neglecting the role of individual differences in the human capacity to read other people’s desires, intentions, knowledge, and beliefs-that is, to have an imperfect theory of someone else’s mind. This study explores the implications of instilling agency theory with a more realistic account of this (bounded) human capacity.

Purpose As the concept of mindfulness gains popularity in the workplace, there is a need to understand the extent to which mindfulness-related practices are integrated into training and development activities and the impact of these practices on employees and organizations. The purpose of this study is to provide an overview of the scope of mindfulness as an intervention in the workplace and to identify outcomes of mindfulness-related training activities at the individual, job/work, team/group and organizational levels. Design/methodology/approach Torraco (2005) and Briner and Denyer's (2012) four steps (search, selection, analysis and synthesis) for conducting an integrative literature review were used for this study. This method enabled us to compare and contrast relevant articles, integrate distributed information, create new knowledge and provide research directions on mindfulness practices in work settings. Findings Through a revision of 28 empirical studies, the authors found that mindfulness-based training is an effective intervention for organizations to improve mental health, wellbeing and performance of employees. A total of 51 significant outcomes of mindfulness-related training categorized at the individual (23), job/work (17), group/team (7) and organizational (4) levels were identified. Practical implications Despite the benefits of mindfulness training, according to the research, only a handful of organizations have rolled-out this program for employees. The authors recommend that industry leaders and managers take a proactive approach and incorporate mindfulness-related practices as part of their professional development training for employees at all levels to improve personal and professional growth and performance. Originality/value This paper extends the emerging literature on mindfulness by providing a comprehensive summary of the consequences of mindfulness training at a multilevel context within the human resource development domain.

The problem of choosing effective means and methods of monitoring the results of test diagnostics of multifunctional distributed objects is relevant and unresolved today due to the large size, the interaction of many factors and the complexity of the task. The decision of the specified tasks will allow to develop and implement as a part of the corresponding automated information system the formalized device of the description of methods and means of quality control of the managed objects and processes. Evaluating the results of a test diagnosis is a difficult task, as it can be weighed over several stages of diagnosis and using various tools and methods. Therefore, it is important to obtain adequate estimates of atomic diagnostic objects (in the proposed diagnostic model - elementary functions), and then determine the qualitative estimates of their formed components of the types of providing the diagnostic object. To form a quantitative assessment of each level (elementary functions, groups of functions, subsystems and types of support in general), the use of additive integro-differential evaluation criterion (AIDCO), based on the results of test diagnostics of these atomic objects of control. AIDCO's linear format requires an analysis of the impact of each differential assessment (the result of the implementation of a particular test) on the integrated assessment (the degree of performance of elementary functions). At the same time there is a task of the analysis of ways of achievement of desirable (set, limit, etc.) values for achievement of necessary (set) degree of performance of elementary functions. The article proposes general approaches (within the framework of the proposed IDC) to the quantitative evaluation of test diagnosis results in relation to another subject area. Private problems of quantitative evaluation of test results and application of additive integro-differential criterion for evaluation of the degree of performance of elementary functions are also solved.

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

AbstractWhilst lithopanspermia depends upon massive impacts occurring at a speed above some limit, the intact delivery of organic chemicals or other volatiles to a planet requires the impact speed to be below some other limit such that a significant fraction of that material escapes destruction. Thus the two opposite ends of the impact speed distributions are the regions of interest in the bioastronomical context, whereas much modelling work on impacts delivers, or makes use of, only the mean speed. Here the probability distributions of impact speeds upon Mars are calculated for (i) the orbital distribution of known asteroids; and (ii) the expected distribution of near-parabolic cometary orbits. It is found that cometary impacts are far more likely to eject rocks from Mars (over 99 percent of the cometary impacts are at speeds above 20 km/sec, but at most 5 percent of the asteroidal impacts); paradoxically, the objects impacting at speeds low enough to make organic/volatile survival possible (the asteroids) are those which are depleted in such species.
