Abstract

The chapter discusses my response to the urgent need for a pedagogy that would effectively promote Israeli teachers’ meta-representational and particularly Visual Representational competencies in order to prepare new generations of school students to fully and successfully navigate the diverse, rich multimodal information that they encounter in the postmodern visual world. Currently, although VRs widely permeate school curricula, learners’ mass media sources for information gathering, and even matriculation testing, students’ meta-representational competence (MRC) are not intentionally developed to enable their dealing with visually transmitted information and their mindful manipulation of it for achieving their goals. VRs usages have been shown to be superficial, implicit, inadequate to utilize VRs’ potential for promoting knowledge acquisition and understanding, and even frequently erroneous. Following a short discussion of the constructs of Meta-Visual Representational Competencies and pedagogy, and potential institutional obstacles for introducing VRs, I propose core pedagogical guidelines for promoting such competencies in teachers, based on evidence collected continually over a decade of work with teachers at Haifa, Israel, while designing, developing, and refining this pedagogy in preservice teacher training and other programs at the University of Haifa and inservice frameworks. Each guideline is operationalized into tasks and activities designed for achieving its specific purpose, focusing on the application of these suggested guidelines in preservice teacher development program. The MRC-promoting pedagogy was designed and developed while keeping in mind the notion that a pedagogy should be flexible, adaptable to different instructional styles, goals, and contexts, and based on guidelines that are operationalized into detailed instructional plans for achieving specific goals, in accordance with teachers’ preferences.

Abstract

Purpose

Vacation rentals (VRs) are growing in popularity and have disrupted the lodging industry. But they are also controversial because they can literally disrupt quiet residential neighborhoods. There is little research on users of VRs.

Design/methodology/approach

An online survey of 10,000 festival attendees in San Francisco determined if they stayed in VR or commercial lodging and their spending. A second survey of 402 respondents who stayed in a VR asked about their motivations for renting a VR and their evaluation of the experience.

Findings

Results showed users of VRs were motivated by low cost, a convenient location and the nature of the neighborhood. VR user groups were more likely to rent high-end properties, than commercial users. But on a per-person per-day basis, VR users spent $183 on lodging, compared with $264 spent by those opting for a CL. Over half of the respondents stated that the availability of VRs increased the likelihood of them attending the event.

Practical implications

Results suggest that VRs help cover housing costs of VR owners and provide a desired, unique and low-priced lodging opportunity, which can encourage attendance at events. But VRs have both positive and negative disruptive impacts, and more regulation is coming in high-profile urban tourist destinations to mitigate negative effects.

Originality/value

This study consists of original research into VRs, which is a rapidly evolving component of hospitality industry.

Abstract

Purpose

This paper aims to present the novel methodology of computational simulation of a helicopter flight, developed especially to investigate the vortex ring state (VRS) – a dangerous phenomenon that may occur in helicopter vertical or steep descent. Therefore, the methodology has to enable modelling of fast manoeuvres of a helicopter such as the entrance in and safe escape from the VRS. The additional purpose of the paper is to discuss the results of conducted simulations of such manoeuvres.

Design/methodology/approach

The developed methodology joins several methods of computational fluid dynamics and flight dynamic. The approach consists of calculation of aerodynamic forces acting on rotorcraft, by solution of the unsteady Reynold-averaged Navier–Stokes (URANS) equations using the finite volume method. In parallel, the equations of motion of the helicopter and the fluid–structure-interaction equations are solved. To reduce computational costs, the flow effects caused by rotating blades are modelled using a simplified approach based on the virtual blade model.

Findings

The developed methodology of computational simulation of fast manoeuvres of a helicopter may be a valuable and reliable tool, useful when investigating the VRS. The presented results of conducted simulations of helicopter manoeuvres qualitatively comply with both the results of known experimental studies and flight tests.

Research limitations/implications

The continuation of the presented research will primarily include quantitative validation of the developed methodology, with respect to well-documented flight tests of real helicopters.

Practical implications

The VRS is a very dangerous phenomenon that usually causes a sudden decrease of rotor thrust, an increase of the descent rate, deterioration of manoeuvrability and deficit of power. Because of this, it is difficult and risky to test the VRS during the real flight tests. Therefore, the reliable computer simulations performed using the developed methodology can significantly contribute to increase helicopter flight safety.

Originality/value

The paper presents the innovative and original methodology for simulating fast helicopter manoeuvres, distinguished by the original approach to flight control as well as the fact that the aerodynamic forces acting on the rotorcraft are calculated during the simulation based on the solution of URANS equations.

Abstract

Purpose

The purpose of this study is to explore the construction pattern and the difficulties for China to develop virtual reference services (VRS).

Design/methodology/approach

The paper first analyzes the definition and features of the digital library, and is followed by an introduction to the development of VRS in China. Through literature search and checking web sites, some 400 documents in CNKI have been analysed on VRS from the period of January, 1990 to June, 2005, and the situation in developing VRS and problems existing in the course of doing it in China have been summarized. On the basis of connecting theory and practice on VRS, the paper provides general tactics on how to develop VRS for libraries in China.

Findings

There are some problems existing for China to develop VRS, namely shortage of funds, the information poor, the digital divide, restrictions of information infrastructure, library management, shortage of technical knowledge and user training. The paper projects what may be needed for China to continue its development of VRS in the future. There is a need for appropriate infrastructures, strategies and mechanisms to be established in order to support the diffusion of VRS principles throughout China.

Originality/value

This paper provides some observations and insights on the design and development of VRS in China. It suggests that decision makers in government agencies need to understand the existing gaps in VRS in China. Constructive suggestions are made for China to construct VRS and improve the service level.

Abstract

Purpose

This paper aims to examine the social interactions between Filipino immigrant-hosts residing in New Zealand and their visiting relatives (VRs) or guests from the Philippines using social exchange theory to understand their experiences.

Design/methodology/approach

This qualitative, multi-sited study used in-depth interviews to examine social interactions between Filipino immigrant-host families in New Zealand and their respective visiting relatives from the Philippines.

Findings

Hosting VRs reflects aspects of social exchange theory, and the interdependence and familial obligations related to VR travel demonstrate mutual relations of care. Maintaining relations of care within the family is an ongoing process involving intergenerational relationships that bind together immigrant-host families and their VRs.

Research limitations/implications

The conceptualization of the social interactions between immigrants-hosts and VRs is not generalizable owing to the small sample size and lack of representativeness. However, despite a small sample, this qualitative inquiry uncovered a series of personal meanings and understandings attached to the maintenance of familial bonds.

Practical implications

As immigrant-receiving countries become more culturally diverse through migration, research about other cultures will assist tourism planners in understanding the values and actions of a more varied array of residents. A better understanding of travel experiences and interactions between immigrants and their guests may provide marketers with insights into host-guest dynamics within a VR context, thus potentially enabling tourism marketers to create better marketing campaigns.

Social implications

Future studies may be undertaken from non-Western and Western perspectives that examine the social interactions between hosts and guests in the context of VR travel. Very little research has been conducted that addresses the meanings and understandings attached to these interactions from the perspectives of both hosting and visiting groups. This research highlights the importance of families in tourism, a contrast with the relative blindness of tourism scholarship toward relations of domesticity and sociality.

Originality/value

What separates the social interactions between family members in the context of visiting friends and relatives travel from the traditional host-guest paradigm is that it does not involve strangers. This study uses social exchange theory to examine social interactions between hosts and guests who are familiar with each other.

Abstract

The US Department of Energy (DOE) Energy Library uses Library Systems & Services’ (LSSI) Virtual Reference Desk (VRS) to provide live reference via the Internet. Energy Library reference librarians use VRS to conduct reference interviews by chat, take the patrons to or send Web pages, collaborate on questions, and provide transcripts for patron follow‐up. VRS allows the reference librarians to reach those who cannot or do not come to the library and makes the librarian a reference resource for a wider audience. The Energy Library VRS patrons and their questions have transitioned from mostly DOE headquarters employees looking for codes, policies and similar documents, to mainly non‐DOE people seeking information, increasing the diversity of reference skills needed.

Abstract

Regionalism implying some form of city-region or metropolitan-level planning and governance has long been promoted for multiple reasons albeit with varied success. Experiencing a resurgence in 1990s, regional coordination and cooperation has proven effective in pursuing economic development and bolstering competitiveness. Unfortunately, other voices, such as those promoting regional scale land use planning and management to cultivate more sustainable urban form and settlement patterns became comparatively crowded out. With climate change-related environmental and ecological pressures mounting, the chapter suggests it is time to frame regions as socio-ecological rather than mere socio-economic spaces, thereby placing greater emphasis on ecosystems and ecological land management and a circular, regenerative economy. Using the city-region of Stuttgart (Germany) as exemplar, our contribution initiates an exploration into whether statutory regional planning in combination with various informal tools and a multi-level governance framework allows actors to begin to embed and implement these emerging ecological sustainability concepts.

Abstract

Purpose

Within controlled environments such as prisons or forensic facilities, strong sanctions and other factors can inhibit the expression of offence-linked behaviours otherwise observable in community settings. For example, institutional restrictions may distort the offender’s habitual expression of aggressive behaviours such that the individual’s aggressive characteristics are less intense or observable. Thus, the influences of controlled settings can make it difficult for staff to capture idiosyncratic evidence of change or lack thereof over time or with treatment. The purpose of this paper is to describe an assessment and measurement framework that can be used to assist treatment and correctional staff collectively focus attention on relevant characteristics and behaviours idiosyncratically linked to offending.

Design/methodology/approach

The authors use the terms “offence analogue behaviours (OAB)” to describe proxies of offence behaviours observable in controlled settings and “offence replacement behaviours (ORB)” as the contrasting positive, pro-social skills and strategies that the individual implements to change and manage problem areas linked to aggression and criminality. This paper discusses the application and practical utility of the framework and an associated assessment and measurement tool; the Offence Analogue and Offence Replacement Behaviour Guide (Gordon and Wong, 2009-2013).

Findings

The OAB and ORB Guide has shown to be useful by directing the attention of treatment personnel to the here-and-now offence related behaviours displayed by offenders in custodial settings. In the absence of such focused attention, relevant proxy behaviours can often be masked in these highly controlled environments. The Guide is therefore a useful adjunct to identify such behaviours for treatment and for assessing treatment-related changes.

Research limitations/implications

The OAB/ORB Guide was developed based on a conceptual framework derived from the empirical literature on correctional treatment, risk assessment, psychological theories and clinical practice. While there has been some positive pilot use of the Guide’s utility and preliminary research, at this point, empirical evidence is still lacking.

Practical implications

The OAB/ORB Guide provides quantified and structured guidelines to assess offence proxy and offence replacement behaviours observable day-to-day within controlled environments, such as during custody or supervised release to the community.

Originality/value

This guide was developed to assist staff with the identification, documentation and measurement of idiosyncratic negative and positive offence-related proxy behaviours observable across custodial or supervised contexts. Accordingly, the authors suggest that OAB/ORB guide information can be used to evaluate changes in risk over treatment and/or time. Further, the authors describe how this framework may enhance the efficacy of multi-disciplinary treatment and management teams. Two cases are used to illustrate the application of the Guide.

Abstract

Purpose

As the virtual reference service (VRS) is becoming a standard service of the digital library, efficient collaboration among virtual reference services is also becoming more and more important for information exchange and sharing. This paper seeks to examine existing collaborative VRS systems with a view to achieving collaboration.

Design/methodology/approach

This paper studies existing collaborative VRS (CVRS) systems and analyzes their structures, methods and functions for achieving collaboration.

Findings

Three collaborative structure models are proposed and basic collaborative methods and collaborative functions are concluded. A CVRS reference model is depicted.

Research limitations/implications

Since the study is not based on an exhaustive list of CVRS systems and technologies are always developing, the collaborative structure models, methods and functions presented in this paper are possibly not complete and may need to be adjusted and amended. There is also urgent work to be done to advance and establish related standards and protocols for CVRS.

Practical implications

The study is intended to help libraries to identify quickly the necessary elements and mechanisms for the design of a proper degree of CVRS or to develop or evaluate VRS systems.

Originality/value

This paper proposes and concludes collaborative structure models, methods, functions and a reference model of CVRS. It should prove helpful for libraries wishing to provide CVRS, as well as for further research on CVRS.
