Geology of the Northern Part of the Malad Range, Idaho

Rocks of Paleozoic, Tertiary, and Quaternary age are represented in the northern part of the Malad Range. The Paleozoic rocks are represented by thirteen formations that are characterized lithologically by quartzites, shales, and carbonates. The oldest formation in the mapped area of Paleozoic age is the Brigham Formation, and the youngest formation is the Jefferson Formation of late Devonian age. The rocks of Tertiary age are conglomerates, shales, and limestones and are represented by the Wasatch Formation, the Salt Lake Formation, and boulders. Quaternary rocks include sediments of the Lake Bonneville Group and alluvium. The faults in the mapped area were formed during two periods of movement. The east-west-trending faults, northeast-trending faults, and northwest-trending faults are a consequence of compressional forces during Laramide orogenic activity. The north-south-trending faults were the result of Basin and Range block faulting during middle and late Tertiary times

Fast transport of cobalt in thorium

Three investigations associated with the fast transport behavior of cobalt in thorium have been conducted. These include (1) a study of a metastable ThCo[subscript] x phase and the solid solubility of cobalt in thorium in dilute thorium-cobalt alloys, (2) a study of the mechanism of fast diffusion of cobalt in thorium using diffusion and internal friction experiments and (3) a study of the thermotransport behavior of cobalt in thorium;A metastable plate phase, having a stoichiometry of about ThCo[subscript]0.08, forms in alloys containing greater than 0.004 at.% Co that are quenched from the single-phase field. Upon aging between 773 and 1073 K the plate phase transforms to rod-like precipitates of the equilibrium Th[subscript]7Co[subscript]3 phase. The solid solubility of cobalt in thorium increases from 0.05 at.% at 1120 K to 0.4 at.% at 1350 K according to the relation, c[subscript] s (at.%) = 7044 exp(-110.5 kJ mol[superscript]-1/RT). The terminal solid solubility at the eutectic temperature of 1373 K is 0.45 at.%;The activation energy for diffusion of cobalt in [alpha] thorium is 83.7 kJ/mol whereas that associated with the anelastic relaxation process for cobalt in thorium is 78.0 kJ/mol. The diffusion and internal friction results can be interpreted as supporting either the host-solute diplon mechanism or the interstitial mechanism of fast diffusion. The observed cobalt internal friction peak may be due to a host-solute diplon or a substitutional-interstitial pair;The heat of transport, Q*, for cobalt in thorium was determined by the single-phase steady-state technique and a new technique referred to as the two-phase nonsteady-state technique. Q* is temperature dependent, decreasing from about 20 kJ/mol at 1125 K to about -61 kJ/mol at 1458 K and is described by the relation, Q* = 274 - 0.24 T kJ/mol. The observed temperature dependence of Q* is consistent with a current model for the electronic contribution to Q*

Assessing Electronic Voice Phenomena through Speech Science

Electronic Voice Phenomena (EVP) are unexplained voices captured on audio recording, allegedly paranormal in nature (Buckner & Buckner, 2012). Little research exists on listener’s perception of EVPs to date. The field of speech science involves the study of the production, transmission, and perception of human speech. Many concrete elements from the study of speech science have the potential to be applied to the interpretation of EVP content. Several works of literature were reviewed to assess current EVP analysis practices Interviews were conducted with various paranormal investigation societies across the nation to gather information on the general practices involved in EVP collection, analysis, interpretation, and use. Responses collected through interviews with paranormal investigators suggests that the process of collecting and identifying an EVP is a thorough and systematic process, but the interpretation process is lacking. No societies report experience collaborating with a speech professional or utilizing speech analysis in order to assist in their interpretation. Research is warranted on listeners’ perception of the smaller units and elements of speech and the reliability across listeners, as well as acoustical analysis of EVP speech content

The work-related affordances of business travel: a disaggregated analysis of journey stage and mode of transport

Sociological understanding of how business travellers make use of travel time is somewhat lacking. This article addresses this gap in knowledge via presenting an analysis of survey-based data collected from business people travelling by plane, train and car. Through disaggregating the data by travel mode, journey stage, technology use and task type the article provides a level of granular detail in the general patterns of business travellers’ travel time behaviour not previously provided by other surveys. Utilizing the concept of ‘affordances’, the article shows how the type of work activities undertaken are shaped by the dynamic interaction between the characteristics in the travel environment, the type of work tasks undertaken and work technologies utilized in carrying out these tasks and the active choices of business travellers

Can Job Redesign Interventions Influence a Broad Range of Employee Outcomes by Changing Multiple Job Characteristics? A Quasi-Experimental Study

Many job redesign interventions are based on a ‘multiple mediator/multiple outcome’ model in which the job redesign intervention indirectly influences a broad range of employee outcomes by changing multiple job characteristics. As this model remains untested, the aim of this study is to test a ‘multiple mediator/multiple outcome’ model of job redesign. Multilevel analysis of data from a quasi-experimental job redesign intervention in a call centre confirmed the hypothesized model and showed that the job redesign intervention affected a broad range of employee outcomes (i.e., employee well-being, psychological contract fulfillment, and supervisor-rated job performance) through changes in two job characteristics (i.e., job control, feedback). The results provide further evidence for the efficacy and mechanisms of job redesign interventions

Group Norms in Virtual Work: New Directions

Despite the increasing implementation of virtual work arrangements (e.g., global virtual teams, online communities, technology-mediated collaboration) in modern organizations, virtuality (i.e., reliance on technology rather than face-to-face communication) can pose many potential challenges to effective group functioning and outcomes. Although, researchers have recognized the importance of having clear and shared group norms for behavior in order to facilitate more effective virtual work, this research area remains relatively underdeveloped. In this symposium, we convene an international group of researchers whose work extends this critical, but still nascent, research domain. The papers include both theoretical as well as lab and field empirical studies that examine how different types of group norms or norm- related constructs work in conjunction with virtuality to impact important dynamics and outcomes in different types of virtual work environments. Collectively, the studies offer significant research extensions and new directions for understanding the role of group norms in facilitating effective virtual work

The Role of Norms in Virtual Work: A Review and Agenda for Future Research

Although existing literature points to the importance of developing shared norms in virtual work and there is some work on norms within online communities, there is little research focusing specifically on how different types of norms operate within virtual work environments. Because differences in expectations across locations can result in increased conflict and reduced motivation and can hamper cooperation and performance within virtual environments, we chose to address this gap in current research and to edit a special issue on the topic.

Flight service evaluation of an advanced composite empennage component on commercial transport aircraft. Phase 1: Engineering development

The empennage component selected for this program is the vertical fin box of the L-1011 aircraft. The box structure extends from the fuselage production joint to the tip rib and includes the front and rear spars. Various design options were evaluated to arrive at a configuration which would offer the highest potential for satisfying program objectives. The preferred configuration selected consists of a hat-stiffened cover with molded integrally stiffened spars, aluminum trussed composite ribs, and composite miniwich web ribs with integrally molded caps. Material screening tests were performed to select an advanced composite material system for the Advanced Composite Vertical Fin (ACFV) that would meet the program requirements from the standpoint of quality, reproducibility, and cost. Preliminary weight and cost analysis were made, targets established, and tracking plans developed. These include FAA certification, ancillary test program, quality control, and structural integrity control plans

Vive la différence: biogenesis and evolution of microRNAs in plants and animals

MicroRNAs are pervasive in both plants and animals, but many aspects of their biogenesis, function and evolution differ. We reveal how these differences contribute to characteristic features of microRNA evolution in the two kingdoms
