Coastal marine habitat mapping using multi-beam acoustics, video data and a decision tree classifier on the temperate south-east Australian continental shelf

In this habitat mapping study, multi-beam acoustic data are integrated with extensive, precisely geo-referenced video validation data in a GIS environment to classify benthic substrates and biota at a 33km2 site in the near shore waters of Victoria, Australia. Using an automated decision-tree classification method, 5 representative biotic groups were identified in the Cape Nelson survey area using a combination of multi-beam bathymetry, backscatter and derivative products. Rigorous error assessment of derived, classified maps produced high overall accuracies (>85%) for all mapping products. In addition, a discrete multivariate analysis technique (kappa analysis) was used to assess classification accuracy. High-resolution (2.5m cell-size) representation of sea floor morphology and textural characteristics provided by multi-beam bathymetry and backscatter datasets, allowed the interpretation of benthic substrates of the Cape Nelson site and the communities of sessile organisms that populate them. Non-parametric multivariate statistical analysis (ANOSIM) revealed a significant difference in biotic composition between depth strata, and between substrate types. Incorporated with other descriptive measures, these results indicate that depth and substrate are important factors in the distributional ecology of the biotic communities at the Cape Nelson study site. BIOENV analysis indicates that derivatives of both multi-beam datasets (bathymetry and backscatter) are correlated with distribution and density of biotic communities. Results from this study provide new tools for research and management of the coastal zone.

Documentary display : re-viewing nonfiction film and video

Not all documentary films and videos are sober depictions of the real world. Documentary representations can present expressive, entertaining and spectacular images. This book examines such innovative approaches as they occur within the process of 'documentary display' - a practice which emphasises the visual attractions of documentary representation. Works of documentary display explore modes of exhibitionistic 'showing' in which sensation is frequently the vehicle of cognition and knowledge. Such a display is analysed within the popular and prominent forms of found-footage film, 'rockumentary', the city film, nonfiction surf film and video, and certain views of natural science topics. This accessible and informed study - with its focus on entertaining, popular, spectacular and sensational froms of nonfiction representation - makes an important contribution to theoretical analyses of documentary film and video

Tolling for the luckless, the abandoned and forsaked : therapeutic jurisprudence and international human rights law as applied to prisoners and detainees by forensic psychologists

Objectives. There has been an explosion of interest in therapeutic jurisprudence as both a filter and lens for viewing the extent to which the legal system serves therapeutic or anti-therapeutic consequences. However, little attention has been paid to the impact of therapeutic jurisprudence on questions of international human rights law and the role of forensic psychologists. The paper aims to provide an intersection between human rights, therapeutic jurisprudence, and forensic psychology.

Method. Human rights are based on legal, social, and moral rules. Human rights literature generally considers legal rights but such policy statements do not provide principles to guide forensic psychologists in addressing moral or social rights. Therefore, a framework to guide forensic psychologists is required.

Conclusion. As duty-bearers, forensic psychologists need to address the core values of freedom and well-being in rights holders (in this instance, prisoners and detainees with a mental illness). The paper proposes that human rights principles can add to the normative base of a therapeutic jurisprudence framework, and in-turn, therapeutic jurisprudence can assist forensic psychologists to actively address human rights.

Offender rehabilitation : a normative framework for forensic psychologists

Community protection from offenders is addressed through punishment, deterrence, incapacitation, and/or rehabilitation. The current public policy debate about community protection refers to community rights as opposed to offender rights as if the two are mutually exclusive. However, in this article it will be argued that offender rehabilitation can enhance community protection if it addresses community rights and offender rights. The author proposes a normative framework to guide forensic psychologists in offender rehabilitation. The normative framework considers psychological theory—the risk-need model to address community rights and the good lives model to address offender rights. However, forensic psychologists operate within the context of the criminal justice system and so legal theory will also be considered. Therapeutic jurisprudence can balance community rights and offender rights within a human rights perspective. The proposed normative framework guides forensic psychologists in the assessment of risk, the treatment of need, and the management of readiness in balancing community rights and offender rights. Within a human rights perspective, forensic psychologists have a duty to provide offenders with the opportunity to make autonomous decisions about whether to accept or reject rehabilitation.

A scalable and extensible segment-event-object-based sports video retrieval system

Sport video data is growing rapidly as a result of the maturing digital technologies that support digital video capture, faster data processing, and large storage. However, (1) semi-automatic content extraction and annotation, (2) scalable indexing model, and (3) effective retrieval and browsing, still pose the most challenging problems for maximizing the usage of large video databases. This article will present the findings from a comprehensive work that proposes a scalable and extensible sports video retrieval system with two major contributions in the area of sports video indexing and retrieval. The first contribution is a new sports video indexing model that utilizes semi-schema-based indexing scheme on top of an Object-Relationship approach. This indexing model is scalable and extensible as it enables gradual index construction which is supported by ongoing development of future content extraction algorithms. The second contribution is a set of novel queries which are based on XQuery to generate dynamic and user-oriented summaries and event structures. The proposed sports video retrieval system has been fully implemented and populated with soccer, tennis, swimming, and diving video. The system has been evaluated against 20 users to demonstrate and confirm its feasibility and benefits. The experimental sports genres were specifically selected to represent the four main categories of sports domain: period-, set-point-, time (race)-, and performance-based sports. Thus, the proposed system should be generic and robust for all types of sports.

Adaptive fusion of gait and face for human identification in video

Most work on multi-biometric fusion is based on static fusion rules which cannot respond to the changes of the environment and the individual users. This paper proposes adaptive multi-biometric fusion, which dynamically adjusts the fusion rules to suit the real-time external conditions. As a typical example, the adaptive fusion of gait and face in video is studied. Two factors that may affect the relationship between gait and face in the fusion are considered, i.e., the view angle and the subject-to-camera distance. Together they determine the way gait and face are fused at an arbitrary time. Experimental results show that the adaptive fusion performs significantly better than not only single biometric traits, but also those widely adopted static fusion rules including SUM, PRODUCT, MIN, and MAX.

Where the home in valley meets the damp dirty prison : a human rights perspective on therapeutic jurisprudence and the rule of forensic psychologists in correctional settings

The roles of forensic psychologists in coerced environments such as corrections include that of treatment provider (for the offender) and that of organizational consultant (for the community). This dual role raises ethical issues between offender rights and community rights; an imbalance results in the violation of human rights. A timely reminder of a slippery ethical slope that can arise is the failure of the American Psychological Association to manage this balance regarding interrogation and torture of detainees under the Bush administration. To establish a “bright-line position” regarding ethical practice, forensic psychologists need to be cognizant of international human rights law. In this endeavor, international covenants and a universal ethical code ought to guide practice, although seemingly unresolveable conflicts between the law and ethics codes may arise. A solution to this problem is to devise an ethical framework that is based on enforceable universally shared human values regarding dignity and rights. To this end, the legal theory of therapeutic jurisprudence can assist psychologists to understand the law, the legal system, and their role in applying the law therapeutically to support offender dignity, freedom, and well-being. In this way, a moral stance is taken and the forensic role of treatment provider and/or organizational consultant is not expected to trump the prescriptions and the proscriptions of the law.

Accountability and dignity : ethical issues in forensic and correctional practice

Our aim in the special issue is to address some of the more abstract and fundamental ethical problems evident in the criminal justice system and to inquire into their significance for those individuals who assess and deliver rehabilitation programs to offenders. In order to provide an appropriate theoretical framework for an investigation of ethical concerns in the forensic and correctional practice domains, we first outline an ethical framework that is intended to help practitioners reflect systematically on their practice [Ward, T., & Syversen, K., (2009). Vulnerable agency and human dignity: An ethical framework for forensic practice. Aggression and Violent Behavior, 14, 94–105]. Second, we explicitly examine the relationship between two normative frameworks evident within the criminal justice system, punishment and rehabilitation, and inquire into their relationship. Finally, we briefly describe each of the papers comprising the special issue.
