Chaotic Region

This short paper is focused on the bifurcation theory found in map functions called evolution functions that are used in dynamical systems. The most well-known example of discrete iterative function is the logistic map that puts into evidence bifurcation and chaotic behavior of the topology of the logistic function. We propose a new iterative function based on Lorentizan function and its generalized versions, based on numerical study, it is found that the bifurcation of the Lorentzian function is of second-order where it is characterized by the absence of chaotic region.

Practical Implications

Purpose The purpose of this paper is to consider primary prevention from the perspective of person-based crime prevention. This crime prevention measure is illustrated by an Australian case study. The report also recognises the integral role the community plays in the delivery of primary person-based crime prevention. Design/methodology/approach This short paper adopts a case study approach. Findings The paper illustrates the purpose and achievements of primary person-based crime prevention, including the success it has in reducing crime and improving feelings of safety in the community. The important role of community members and their contribution to this crime prevention method is offered. Practical implications The practical implications this paper offers are to ensure community members are involved in the delivery of primary person-based crime prevention, to explicitly measure the contribution community members make to primary person-based crime prevention initiatives, to explicitly measure the contribution primary person-based crime prevention makes to the reduction of crime, and to build on the known success of primary person-based crime prevention through the implementation of more initiatives within this area of crime prevention. Originality/value Primary person-based crime prevention can be overlooked in favour of primary place-based crime prevention. This short paper offers an insight into an overlooked aspect of crime prevention.

Expected Outcomes

This short paper reports on the case of a tertiary level French language practitioner self-training in using Moodle Quiz during the Covid-19 pandemic online emergency remote teaching (Hodges et al., 2020). As no teacher training program included a topic such as ‘how to deal with the pandemic’, switching to online teaching was done under emergency conditions (MacIntyre, Gregersen, & Mercer, 2020). The practitioner had taken advantage of the situation and explored ways of self-training. She took advantage of Moodle Quiz (MQ) affordances. She experimented with different ways MQ could be used to construct a diverse number of quiz activities, embedded with audio and video, infused with elements of constructivism, and aiming at catering for the aims and expected outcomes of the specific students and course. Self-training helped the practitioner face the challenges of online emergency teaching as she developed knowledge, skills, and experiences necessary for creating online interactive activities.

Panacoustic surveillance can be low-intensity and mundane, but when taken to its extreme, it is coordinated with physical violence to create an atmosphere of hallucinatory fear. Our entry point into this problem is through a case study of the Saydnaya torture prison in Syria, a terrifying and opaque architecture of power. This short paper draws from the earwitness art and human rights activism of Lawrence Abu Hamdan concerning Saydnaya in collaboration with Amnesty International: from our analysis of the prison, we extrapolate lessons of panacoustic technologies more broadly, which are not necessarily or immediately violent but nonetheless disempower subjects by constraining their behaviors and rendering walls indefensibly porous. In developing a nascent theory of panacoustic surveillance, this paper makes two distinct contributions to surveillance studies. First, it puts sound and surveillance studies scholars into dialogue to echo Hamdam’s argument that walls do not represent an absolute barrier but a corporeal medium by which power and knowledge can permeate and reflect as vibration. Second, our discussion articulates a politics of transparency and accountability that helps rethink notions of actuarial surveillance as not only a form of top-down statistical and biopolitical monitoring and governance but also as a means of developing panacoustic audits that seek to hold governments and other human rights abusers to account.

This short paper aims to present pros and cons of current usage of ready-to-use drone images in the field of forestry also considering flight planning and photogrammetric processes. The capabilities of DJI Phantom 4, which is the low cost drone producing by Dji company, was evaluated through sample flights in Cinarpinar Forest Enterprise Chief in Kahramanmaras in Turkey. In addition, the photogrammetric workflow of obtained images and automated flight were presented with respect to capabilities of available software. The flight plans were created by using Pix4DCapture software with android based cell phone. The results indicated that high-resolution imagery obtained by drone can provide significant data for assessment of forest resources, forest roads, and stream channels.

Survival Curves

Abstract An evolutionary approach to historical linguistics can be enlightening when not only the mechanisms, but also the statistical methods are considered from neighboring disciplines. In this short paper, we apply survival analysis to investigate what factors determine the lifespan of words. Our case study is on post-classical Greek from the 4th century BC to beginning of the 8th century AD. We find that lower frequency and phonetically longer lexemes suffer earlier deaths. Furthermore, verbs turn out to have higher survival rates than adjectives and nouns survival analysis.

Post Disaster

This paper describes the post-disaster reconstruction in the Tohoku region after the 2011 earthquake. Nine years have passed since the Great East Japan Earthquake and Tsunami occurred, and many efforts have been made since to rebuild the devastated territories. Some Japanese architects and urban planners have seen the recovery as a window of opportunity to aim for more resilient cities. Nevertheless, building disaster-resilient communities remains a challenging task. This short paper presents the initiatives made to improve refugees’ social conditions in disaster-relief housing, using the case study of Iwanuma’s relocation project. Concluding remarks suggest that many efforts have been made to improve the social aspect of disaster-relief housing in Japan, for example through the development of community spaces or the pursuit of friendlier dwellings.

Chua's Circuit

This short paper discusses the effect of the internal resistance of the inductor in Chua's circuit which is often neglected by many even when actual implementation is intended. Using a fixed point stability analysis it is shown that varying the inductor resistance it is possible to suppress or allow chaotic oscillations. The results reported in this paper have clear consequences for the control of Chua's circuit.
