THE POLITICAL ECONOMY OF BITCOIN

The recent proliferation of bitcoin has been a boon for users but might pose problems for governments. Indeed, some governments have already taken steps to ban or discourage the use of bitcoin. In a model with endogenous matching and random consumption preferences, we find multiple monetary equilibria including one in which bitcoin coexists with official currency. We then identify the conditions under which government transactions policy might deter the use of bitcoin. We show that such a policy becomes more difficult if some users strictly prefer bitcoin because they can avoid other users holding the official currency in the matching process.

Evaluation of a family-based substance abuse prevention program targeted for the middle school years

A family-based substance abuse prevention program was evaluated which emphasizes family cohesion, school and peer attachment, self-esteem, and attitudes about adolescent use of alcohol and tobacco. The program was implemented in rural communities and targeted families with students entering middle or junior high school. Baseline surveys were conducted with students and parents in four schools and were readministered one year later. Because the program was voluntary, a quasi-experimental design was used to compare participants (29 students and 28 parents) and nonparticipants (268 students and 134 parents). Analyses of covariance indicated that student participants, as compared to nonparticipants, had higher family cohesion, less family fighting, greater school attachment, higher self-esteem, and believed that alcohol should be consumed at an older age at the one year follow-up. There were fewer significant results for parent participants. Strategies for involving parents in prevention programs are discussed.     

An evaluation of school district guidance and counseling programs: Procedures and results

This evaluation examines the administrative history, staffing levels, and content of school district guidance and counseling activities. Case studies were made in a 50% random sample of a district's 45 elementary schools. Eight hundred teachers, parents, and students were interviewed. All school plans were reviewed. Five-year staffing patterns and staff changes were studied. All district staff with guidance and counseling responsibilities recorded characteristics of guidance and counseling contacts for 15 days. Schools with and without counselors were studied to estimate differences in who receives services and what is provided. Results show systematic differences in the level and kind of services provided secondary and elementary students. Approximately one-third of the schools studied had stable programs. Schools with stable programs provided a broader range of services and distributed them in a more equitable manner.     

Communicating Fish Consumption Advisories in California: What Works,What Doesn’t

State agencies face many challenges in creating sport fish consumption advisories that can be readily understood by diverse populations. In this study, our objectives were to identify barriers to understanding consumption advisories and recommend more effective approaches for communicating advisory concepts. We conducted key informant interviews with demographically diverse consumers of sport fish from the Sacramento‐San Joaquin Delta watershed in California to explore how intended audiences perceive consumption advisories and identify factors that influence comprehension. Some barriers to communication included the use of portion sizes that departed from commonly consumed amounts, poorly understood terminology, misleading category headings, and ineffective visual tools. Comprehension was enhanced when advisory information did not contradict existing beliefs about fish or fish consumption, and when advisories provided information about contaminant levels in specific kinds of fish. Using certain methods, such as portion sizes that reflect commonly consumed amounts, mercury meters to convey contaminant levels, three advice categories (e.g., high, medium, low), and population definitions that identify specific age ranges, improved the clarity of advisory concepts for intended audiences.     

Leadership and Crew Resource Management in High-Reliability Organizations: A Competency Framework for Measuring Behaviors

High-reliability organizations (HROs) have emerged across a number of highly technical, and increasingly automated industries (e.g., aviation, medicine, nuclear power, and oil field services). HROs incorporate complex systems with a large number of employees working in dynamic, and potentially dangerous environments. Effectively managing contingencies in HROs, to simultaneously promote safe and efficient behaviors is a daunting task. Crew Resource Management (CRM) has emerged in HROs as a highly effective approach to training and sustaining essential skills within work teams operating across a large workforce. CRM provides a competency framework that enables adherence to standard work instructions while, at the same time, encourages adaptive variance in responding to effectively manage current environmental circumstances that depart from normal routines. This paper considers the development of CRM across several high-reliability industries, develops a behavior analytic account of CRM behaviors, and describes an approach to measuring behaviors within simulated and actual work environments.     

The Face-to-Face Light Detection Paradigm: A New Methodology for Investigating Visuospatial Attention Across Different Face Regions in Live Face-to-Face Communication Settings

We introduce a novel paradigm for studying the cognitive processes used by listeners within interactive settings. This paradigm places the talker and the listener in the same physical space, creating opportunities for investigations of attention and comprehension processes taking place during interactive discourse situations. An experiment was conducted to compare results from previous research using videotaped stimuli to those obtained within the live face-to-face task paradigm. A headworn apparatus is used to briefly display LEDs on the talker's face in four locations as the talker communicates with the participant. In addition to the primary task of comprehending speeches, participants make a secondary task light detection response. In the present experiment, the talker gave non-emotionally-expressive speeches that were used in past research with videotaped stimuli. Signal detection analysis was employed to determine which areas of the face received the greatest focus of attention. Results replicate previous findings using videotaped methods.     

Using Davis's Perceived Usefulness and Ease-of-use Instruments for Decision Making: A Confirmatory and Multigroup Invariance Analysis

As key components of Davis's technology acceptance model (TAM), the perceived usefulness and perceived ease-of-use instruments are widely accepted among the MIS research community as tools for evaluating information system applications and predicting usage. Despite this wide acceptance, a series of incremental cross-validation studies have produced conflicting and equivocal results that do not provide guidance for researchers or practitioners who might use the TAM for decision making. Using a sample of 902 “initial exposure” responses, this research conducts: (1) a confirmatory factor analysis to assess the validity and reliability of the original instruments proposed by Davis, and (2) a multigroup invariance analysis to assess the equivalence of these instruments across subgroups based on type of application, experience with computing, and gender. In contrast to the mixed results of prior cross-validation efforts, the results of this confirmatory study provide strong support for the validity and reliability of Davis's sixitem perceived usefulness and six-item ease-of-use instruments. The multigroup invariance analysis suggests the usefulness and ease-of-use instruments have invariant true scores across most, but not all, subgroups. With notable exemptions for word processing applications and users with no prior computing experience, this research provides evidence that the item-factor loadings (true scores) are invariant across spread sheet, database, and graphic applications. The implications of the results for managerial decision making are discussed.     

Intimate Communication across Borders: Spousal Labor Migration and Recent Partner Communication about Family Planning in Nepal

Abstract

Amid widespread labor migration in Nepal, spousal separation may affect partner communication about intimate topics like family planning. We examined the association between spousal migration experience and partner communication about family planning using survey responses from 1,793 married Nepali women (ages 18–49 years) with a child under 5 years. More than 60% of women had recently migrating spouses. Forty-seven percent reported recent partner communication about family planning. Women with currently migrating spouses were significantly less likely than women with non-migrant spouses to report recent spousal discussions about family planning. Recent partner communication about family planning varied by destination and duration of current migration. Future programs designed to fulfill the reproductive health needs of transregional or transnational couples should address partner communication about family planning.     

To Farm or Not to Farm: Rural Dilemma in Russia and Ukraine

Abstract Employing primary data collected in the summer of 1991 in a representative survey of two farming areas in the territory of the republics of Russia and Ukraine, this study addresses the issue of the future involvement of collective and state-farm workers in private farming. Through the use of a LISREL model, it is argued that those who have been involved in small-scale private farming show no interest in expanding their farm operations or in buying or leasing additional land for farming. Moreover, it is maintained that those who intend to become farmers in privately owned and operated farms are more likely to be young, educated, and to some extent, ideologically committed to the free market system. A combination of structural constraints and a lack of knowledge regarding what to expect in the future can be viewed as possible explanations of the answers provided by respondents.
