Abstract

Purpose

The purpose of this paper is to present a simulation and realization of the different types of chaotic attractors using the generalized Chua's circuit equations.

Design/methodology/approach

This paper presents n+n‐scroll and 2D n‐scroll chaotic attractors by introducing multiple breakpoints to the nonlinearity. Two piece‐wise linear elements controlled with x‐ and y‐state space variables are used. Chaotic scrolls are originated through both x‐ and y‐axes. The current feedback operational amplifiers are preferred in the experimental circuits because of their wide bandwidth.

Findings

It is possible to increase the number of the scrolls in two directions by varying the number of breakpoints in the piece‐wise linear characteristics or changing the location of equilibrium points of the system on 2D‐plane. Theoretically developed behaviors are also experimentally tested.

Originality/value

The excellent adaptation is observed between theoretical and experimental results. This paper also provides useful information about how to build the multiple breakpoints nonlinear elements using the simulation results.

Abstract

Purpose

The purpose of this research is to examine Gitga'at First Nation approaches and objectives concerning the use of local biological and cultural resources through the lens of a locally‐driven proposal to establish an eco‐cultural tourism enterprise.

Design/methodology/approach

This project was developed in collaboration with the Gitga'at First Nation and employed a qualitative case study approach. Primary data gathering techniques were active participation, semi‐structured interviews, focus group discussions and work with key informants.

Findings

Participant responses highlight the interconnectivity and importance of social, ecological and cultural integrity in local economic development. Three major principles for resource use were widely expressed: control and management by Gitga'at; equitable distribution of any benefits; and the imperative of environmental and cultural sustainability.

Research limitations/implications

Gitga'at band members living within the Gitga'at traditional territory played a central part in this research. Future work could include non‐resident band members. Furthermore, if the Gitga'at decide to move forward with this proposal, further research could examine how the resource use principles discussed here may be applied.

Practical implications

This research provided a forum to explicitly identify research participants' hopes and concerns surrounding eco‐cultural tourism and the possible outcomes of this potential project.

Social implications

This research may be beneficial to other communities interested in eco‐cultural tourism development or other development activities dependent on local resources use.

Originality/value

Although essential to creating economic opportunities that reflect local goals and interests, socio‐cultural dimensions are often overlooked in local economic development. This research explicitly sought to unpack these domains.
