Pathways for Communicating about Objects on Guided Tours

CURATOR THE MUSEUM JOURNAL, Issue 3 2008
Jeff Camhi
Most tour guides rely on rather limited, unidirectional (guide-to-visitor) communication. Instead, this paper outlines six different pathways of communication that are possible among guide, visitors, and object. Each pathway offers several specific types of communicative acts. In addition, 35 guided tours in several different kinds of venue were examined to identify the pathways and types of acts that were used. The professional literature describes other types of acts, and more have been developed at the writer's home museum. All in all, the 58 different types of communicative acts described here present a wide range of opportunities for guides to communicate with visitors. [source]

Polynomial control: past, present, and future

INTERNATIONAL JOURNAL OF ROBUST AND NONLINEAR CONTROL, Issue 8 2007
Vladimír Ku
Abstract Polynomial techniques have made important contributions to systems and control theory. Engineers in industry often find polynomial and frequency domain methods easier to use than state equation-based techniques. Control theorists show that results obtained in isolation using either approach are in fact closely related. Polynomial system description provides input,output models for linear systems with rational transfer functions. These models display two important system properties, namely poles and zeros, in a transparent manner. A performance specification in terms of polynomials is natural in many situations; see pole allocation techniques. A specific control system design technique, called polynomial equation approach, was developed in the 1960s and 1970s. The distinguishing feature of this technique is a reduction of controller synthesis to a solution of linear polynomial equations of a specific (Diophantine or Bézout) type. In most cases, control systems are designed to be stable and meet additional specifications, such as optimality and robustness. It is therefore natural to design the systems step by step: stabilization first, then the additional specifications each at a time. For this it is obviously necessary to have any and all solutions of the current step available before proceeding any further. This motivates the need for a parametrization of all controllers that stabilize a given plant. In fact this result has become a key tool for the sequential design paradigm. The additional specifications are met by selecting an appropriate parameter. This is simple, systematic, and transparent. However, the strategy suffers from an excessive grow of the controller order. This article is a guided tour through the polynomial control system design. The origins of the parametrization of stabilizing controllers, called Youla,Ku,era parametrization, are explained. Standard results on reference tracking, disturbance elimination, pole placement, deadbeat control, H2 control, l1 control and robust stabilization are summarized. New and exciting applications of the Youla,Ku,era parametrization are then discussed: stabilization subject to input constraints, output overshoot reduction, and fixed-order stabilizing controller design.

Tourist shopping experiences and satisfaction

INTERNATIONAL JOURNAL OF TOURISM RESEARCH, Issue 2 2007
Cevat Tosun
Abstract This paper examines tourists' perceived satisfaction with local shopping culture, staff service quality, product value and reliability, physical features of shops, payment methods, and other shopping and shop attributes with special reference to the region of Cappadocia, Turkey. A survey questionnaire was designed and conducted with tourists visiting the region on a guided tour. It was found that the respondents recorded different levels of satisfaction with various attributes of shops and shopping. Based on the research results, it is suggested that providing a higher level of shopping experience for tourists and increasing the contribution of shopping to the regional economy requires supporting indigenous local people via various fiscal and educational instruments to continue producing and retailing authentic handicrafts and souvenir goods. It is believed that this not only is necessary for the achievement of higher levels of tourist satisfaction and greater economic benefits for the local economy but also for achieving the ultimate goal of sustained and sustainable tourism development.

Software Review: Theory and Practice of Econometric Modelling using PcGive10

JOURNAL OF ECONOMIC SURVEYS, Issue 4 2001
Giovanni Urga
This review offers a guided tour to PcGive 10 modules for econometrics analysis of time series (PcGive), limited dependent variable (LogitJD) and static and dynamic panel data analyses (DPD), financial econometric (GARCH) and time series (ARFIMA) modelling. Several empirical applications are reported to illustrate the package. [source]

A guided tour into subcellular colocalization analysis in light microscopy

JOURNAL OF MICROSCOPY, Issue 3 2006
S. BOLTE
Summary It is generally accepted that the functional compartmentalization of eukaryotic cells is reflected by the differential occurrence of proteins in their compartments. The location and physiological function of a protein are closely related; local information of a protein is thus crucial to understanding its role in biological processes. The visualization of proteins residing on intracellular structures by fluorescence microscopy has become a routine approach in cell biology and is increasingly used to assess their colocalization with well-characterized markers. However, image-analysis methods for colocalization studies are a field of contention and enigma. We have therefore undertaken to review the most currently used colocalization analysis methods, introducing the basic optical concepts important for image acquisition and subsequent analysis. We provide a summary of practical tips for image acquisition and treatment that should precede proper colocalization analysis. Furthermore, we discuss the application and feasibility of colocalization tools for various biological colocalization situations and discuss their respective strengths and weaknesses. We have created a novel toolbox for subcellular colocalization analysis under ImageJ, named JACoP, that integrates current global statistic methods and a novel object-based approach. [source]
