Abstract

Mobile robots with dextrous hands and sophisticated sensory systems will require intelligent, knowledge‐based, expert controllers. A design is developed for a robot controller which can acquire task knowledge as it interacts in the world with its human users. The design is based on four reasonable assumptions which lead to a theoretical framework for robot learning systems. The framework is called a multiple‐context learning system. It is a production system with multiple templates for forming productions as the system interacts with the world. Elaborations of the framework and experimental tests of the system are discussed.

Abstract

Purpose

The purpose of this paper is to examine changes in the structures of US farms and lenders and identify prospective implications for federal credit.

Design/methodology/approach

Data from US farm operations for 1996-2014 were adjusted to 2014 values using commodity price indices. Farm size groups were constructed by value of farm production to analyze changes in farm numbers, production, assets, debt, leverage, liquidity, profitability, land tenure, commodity type, contract production, organization type, and use of Farm Service Agency (FSA) direct and guaranteed loans by farm size. Bank, Farm Credit System (FCS), and FSA data from 1996 to 2015 were adjusted to 2014 values. Lender size groups were constructed to analyze changes in bank and association numbers, farm loans, and use of FSA guaranteed loans by lender size.

Findings

The greatest consolidation has been by farms with over $2 million in production. More farm debt is held by large, complex organizations, frequently with multiple operators, more variable income, and greater reliance on production contracts and operating and nonreal estate credit. Large farms have greater leverage, are more profitable, and have a larger share of household income from the farm. Banks and FCS institutions are fewer and larger, yet smaller institutions use FSA guarantees to a greater extent. Larger farms tend to be more reliant on both direct and guaranteed FSA loans and are likely to become more dependent on FSA credit.

Originality/value

Changing farm and lender structure together with softening farm income may require FSA farm loan program changes to meet any increase in loan demand. Policy alternatives are provided to meet changing demand for farm credit.

Abstract

After an overview of the literature on challenges facing library instructors and their coordinators, the chapter describes how the communities of practice model relates to professional development in librarianship, specifically in the area of instructional development. A case study of a community of practice fostered by an instruction coordinator at an academic library is detailed. Academic librarians may encounter several challenges when entering the classroom as library instructors, and instruction coordinators seek to address these and other challenges as they build library instruction programs. By developing a community of practice, instruction coordinators can enable library instructors to learn together. The case study describes how the Instruction Coordinator cultivates library instructor development for members of the Teaching and Learning Team at Loyola University New Orleans’ Monroe Library through a community of practice model. The practical implications for this chapter are that instruction coordinators can establish instructional development opportunities that allow library instructors to enhance their teaching abilities and ultimately further library instruction programs. Communities of practice are well known in several fields and have been discussed in the library literature. This chapter provides additional value to researchers and practitioners through the discussion and application of the concept in the context of library instruction at academic institutions. The case study provides specific examples of how instruction coordinators at other academic libraries can apply the community of practice model and instructional development opportunities to a library instruction program in order to build and sustain a learning culture that supports library instructor development.

Abstract

Purpose

This paper seeks to analyze the use of metaphor in the 1997‐2006 letters to shareholders (LTS) of Nortel Networks Corporation (Nortel). It aims to assess the prevalence of metaphor and changes in the use of metaphor as turnover in corporate leadership took place and as Nortel's financial fortunes changed.

Design/methodology/approach

Metaphors in the LTS are part of a corporation's voluntary disclosures, which in turn may be used for impression management purposes. The paper uses discourse analysis, in particular quantitative and qualitative content analysis, of the LTS to identify key metaphors and to evaluate changes in the prevalence of these metaphors across corporate leaders and during phases of growth and decline.

Findings

Several key metaphors are identified in Nortel's letters to shareholders, including science, journey, vision, construction and theatre. Evidence is also found that demonstrates changes in the prevalence of metaphors across various chief executive officers, and changes in the meaning of metaphors in periods of growth and decline.

Originality/value

The contribution of the paper is to highlight the use of metaphor in the voluntary disclosures (i.e. letters to shareholders) of a major North American corporation during a turbulent decade. The preferences of four very different CEOs are reflected in their choice of metaphor, supporting arguments that metaphor is used in voluntary disclosures as a means of impression management, particularly in relation to trends in corporate financial performance.

Abstract

International students, specifically students who study English for Academic Purposes (EAP), are an increasingly important and large part of the makeup of Canadian post-secondary institutions. As these students have diverse learning needs and goals, institutions need to properly support these learners to be successful in academic settings. A review of the literature explores the increasing need to support this particular student population; approaches to the teaching, learning, and programming of EAP courses and programs; and strategies in and beyond the classroom to support these learners. This chapter offers design considerations and suggests that EAP curricula be integrative in nature. This can be achieved through choosing relevant topics, incorporating experiential learning opportunities, designing collaborative learning tasks, discussing issues of culture, and planning purposeful community connections. Approaching the development of EAP curricula through an integrative lens will ensure learners who are ready for post-secondary studies in academic fields. Classroom examples from the author’s professional experience are offered. Discussion of how to achieve integrative EAP curricula in virtual learning environments is also included.

Abstract

This paper reports on part of a dissertation project on the relationships between learning methods and students’ information behavior in Finland. In this qualitative study, information behavior is studied in the contexts of a problem-based learning curriculum and a traditional curriculum. In 1998, 16 theme interviews were conducted at the Tampere University Medical School, which applied the problem-based learning curriculum and 15 interviews at the Turku University Medical School, in which the traditional curriculum with an early patient contact program was implemented. The focus of this paper is on the concept of information literacy as a part of the students’ information behavior and its relationships with students’ conceptions of learning. The findings indicate that students’ information literacy is developed, on the one hand, through active use of information and sources in connection with real information needs, and, on the other hand, through an educational context which offers opportunities to get different viewpoints on issues. Following the same tendency, the more developed conceptions of learning were mostly held by the students belonging to the problem-based group with simple or developed skills in information literacy, although there were exceptions from this pattern.

Abstract

Independent travelers are those vacationers who have booked only a minimum of their transportation and accommodation arrangements prior to departure on the vacation. Independent travel is an important and growing sector of worldwide tourism. Choice of vacation itinerary for the independent vacation represents a complex series of decisions regarding purchase of multiple leisure and tourism services. This chapter builds and tests a model of independent traveler decision-making for choice of vacation itinerary. The research undertaken employs a two-phase, inductive–deductive case study design. In the deductive phase, the researcher interviewed 20 travel parties vacationing in New Zealand for the first time. The researcher interviewed respondents at both the beginning and the end of their New Zealand vacations. The study compares pre-vacation research and plans, and actual vacation behaviors, on a case-by-case basis. The study examines case study narratives and quantitative measures of crucial variables. The study tests two competing models of independent traveler decision-making, using a pattern-matching procedure. This embedded research design results in high multi-source, multi-method validity for the supported model. The model of the Independent Vacation as Evolving Itinerary suggests that much of the vacation itinerary experienced in independent travel is indeed unplanned, and that a desire to experience the unplanned is a key hedonic motive for independent travel. Rather than following a fixed itinerary, the itinerary of an independent vacation evolves as the vacation proceeds. The independent traveler takes advantage of serendipitous opportunities to experience a number of locations, attractions and activities that they had neither actively researched nor planned.
