The Joint Interagency Field Experimentation (JIFX) event, organized by the Naval Postgraduate School (NPS), is conducted 3-4 times a year at various locations. The four day event can be characterized as an informing system specifically designed to facilitate structured and unstructured communications between a variety of parties—e.g., software developers, inventors, military and civilian users of various technologies, academics, and agencies responsible for identifying and procuring technology solutions—that frequently are constrained in their informing activities in more restrictive venues. Over the course of the event, participants may observe technology demonstrations, obtain feedback from potential users, acquire new ideas about their technologies might be employed and, perhaps most significantly, engage in ad hoc collaborations with other participants. The present paper describes an exploratory case research study that was conducted over a one year period and involved both direct observation of the event and follow-up interviews with 49 past participants in the event. The goal of the research was to assess the nature of participant-impact resulting from attending JIFX, and considering the consistency of the findings with the predictions of various theoretical frameworks used in informing science. The results suggest that participants perceived that the event provided significant value from three principal sources: discovery, interaction with potential clients (users) of the technologies involved, and networking with other participants. These findings were largely consistent with what could be expected from informing under conditions of high complexity: because value generally derives from combinations of attributes rather than from the sum of individual attributes, we would expect that overall value from informing activities will be perceived even though estimates of the incremental value of that informing cannot be made. A revised version of this paper was published in the journal Informing Science: the International Journal of an Emerging Transdiscipline, Volume 18, 2015

This case study illustrates the reduction of severe stuttering by an individually tailored treatment programme. Interventions are derived from a tripartite analysis (Lang, 1971) and include EMG biofeedback, regulated breathing, exposure in vivo to stressful communication situations and cognitive techniques to reduce relapse risk. The role of dysfunctional response system interactions in stuttering is emphasized. Treatment resulted in a marked reduction of stuttering and associated facial contortions during videotaped conversations with strangers and oral reading. Improvement was maintained at one-year follow-up.

A case study is presented of a young woman with an unusual phobia, a fear of babies. Barabasz's (1977) technique of systematic desensitization using psycho-physiological measures was chosen as the main treatment strategy. Difficulties arose as the client was unable to visualise scenes involving babies. Nor could she look at photographs of babies long enough for the hierarchy to be ordered using a psycho-physiological measure (skin conductance). A set of photographs was eventually used for the hierarchy, but it was ordered in terms of the length of time the client could look at the various photographs. Systematic desensitization was carried out using the set of photographs instead of imaginary scenes, together with some in vivo exposure in the latter stages of treatment. At termination the client could approach babies without discomfort. Improvement was maintained at one year follow-up.

‘Skipped generation’ families, consisting of grandparents and grandchildren with parents absent from the home, are frequently served in social work agencies. These families have unique multigenerational patterns and family structures that are important for service providers to recognize. This paper uses a multigenerational systems perspective to highlight the diversity among grandparent-headed households. Twenty families who were previously part of a larger study of stress, well-being, and life satisfaction among caregiving grandparents constituted a follow-up case study involving videotaped family interviews one year after the first study. Three families representing the range of diversity among the twenty are described with accompanying genograms. Differences in structure, interactional processes, and links with prior generations are identified in each case. These examples reveal the strengths and vulnerabilities, as well as the diversity, of grandparent-headed families.

Behaviour change is often a desired outcome for carers and professionals who work with people with learning disabilities and challenging behaviours. Managing these behaviours in the short term is an important step towards this goal. This single case study presents the use of a low arousal approach in managing challenging behaviours in a young man labelled with severe challenging behaviour. This strategy focuses on the interaction of the carers with the client and how their approach has an important impact on the behaviour of the client. The study documents the incidents of challenging behaviour and shows a decline in their frequency from baseline over a one-year period. These gains were maintained at five-month follow-up. The implications for services of these findings are discussed.

Purpose – The purpose of this paper is to provide an assessment of a one-year pilot exploring the joint purchase of e-books via demand-driven acquisition (DDA) conducted by engineering librarians from seven members of the Borrow Direct interlibrary loan partnership. Also provided are observations that may inform future initiatives of a similar nature. Design/methodology/approach – The author presents a case study approach and examination of the results. Findings – The pilot was discontinued as a result of dissatisfaction with its configuration, but it did offer significant financials savings as well as provide accessible copies of mutually acquired titles to each member. The pilot also offered several lessons that can inform future joint e-book endeavors. Originality/value – Multi-institutional joint e-book DDA acquisition has been attempted elsewhere; however, what is unique about this pilot is that it was managed by seven independent institutions without a central legal entity to oversee it. This paper is a follow-up to the author’s presentation at the 80th IFLA World Library and Information Congress, August 16-22, 2014, in Lyon, France.

Mentoring has been explored from various perspectives under different theoretical frameworks. The situation-based mentoring brings a lot of possibilities and sustainabilities to the student teachers. Given the overview on the literature of mentoring, it can be found that the research about mentoring mainly is concerned with English-speaking countries such as US and UK and populates in general teacher education. The research in subject-specific field receives scant attention, such as in Foreign Language Teacher Development (hereafter, FLTD). Finding few reports from China, especially about the novices in ethnical colleges, the empirical study running through one year from in an ethnic college shows that mentoring is a supportive way in FLTD for supporting novices. Under the framework of sociocultural theory, we found that, in addition to improving of teaching skills, mentoring can (1) lessen novices’ stress and ‘reality shock’ in teaching and strengthen the sense of belongings; (2) facilitate novice teachers’ reflection ability and (3) foster novice teachers’ self-efficacy in teaching.

Strong acoustic resonance with acoustic pressures reaching up to 165dB developed in the boiler bank of a package boiler at full load. At first, the resonance developed at a lower frequency in the downstream portion of the tube bank and was suppressed by an acoustic baffle covering the downstream section of the flow channel. After about one year of operation, a second resonant condition developed. Tests confirmed that, again, a strong resonant condition developed at a higher frequency in the unbaffled upstream portion of the flow channel. Computer analysis confirmed that the initial resonance occurred at the first acoustic mode of the flow channel while the follow-up resonance occurred at the second mode of the flow channel expressed as a first-mode resonance in a different (upstream) location. An extension of the acoustic baffle covering the entire depth of the tube bank eliminated the vibration. This paper gives a description of the problem and summarizes the theoretical and experimental results substantiating the findings.

The paper investigates the performance of a combined heat and power system by means of a fully dynamic numerical approach. An ad-hoc library for the simulation of energy conversion systems is developed under the OpenModelica open source platform; the library includes the main components that usually equip a Combined Heat and Power (CHP) system and they can be connected as they are logically connected in the real plant. Each component is modelled by means of equations and correlations that calculate their performance on a time dependent basis. Therefore, many configurations can be evaluated not only in terms of cumulative annual results or average performance, but the instantaneous behavior can be investigated. The numerical library is constructed using the lumped and distributed parameter approach and it is validated by comparing the numerical results with the measured values over a one-year time period. The prediction capabilities of the proposed numerical approach are evaluated by simulating a case study of a health spa. This case study is selected since it is characterized by significant requirements of both thermal and electric energy. The comparison demonstrated that the calculated results are in good agreement with the measurements in terms of both annual values and distribution over the reference period. Furthermore, an optimization algorithm is adopted and linked to the developed library in order to estimate the best size of different components of the CHP system according to a number of constraints. This feature is particularly important when addressing the energy efficiency of a complete system that is depending on a number of interdependent variables. Therefore, the case study is investigated by accounting also for additional technologies that can be further enhance the performance of the system both in terms of energy consumption and economic investment. In particular, the numerical model is used to optimized the CHP energy efficiency by estimating the best trade-off between the reduction of the energy purchased and the overall cost of the system. The application of PV panels and electric energy accumulators is also investigated and the simulation demonstrates that the size of the cogeneration unit equal to 48 kW, the number of PV panels of 299 and the battery capacity of 45 kWh provide the lowest amount of energy purchased, while the best return of investment is obtained by the CHP unit of 40 kW along with 109 PV panels and a battery of 40 kWh.
