Abstract
Purpose
VirtuNav is a haptic-, audio-enabled virtual reality simulator that facilitates persons with visual impairment to explore a 3D computer model of a real-life indoor location, such as a room or building. The purpose of this paper is to aid in pre-planning and spatial awareness, for a user to become more familiar with the environment prior to experiencing it in reality.
Design/methodology/approach
The system offers two unique interfaces: a free-roam interface where the user can navigate, and an edit mode where the administrator can manage test users, maps and retrieve test data.
Findings
System testing reveals that spatial awareness and memory mapping improve with user iterations within VirtuNav.
Research limitations/implications
VirtuNav is a research tool for investigation of user familiarity developed after repeated exposure to the simulator, to determine the extent to which haptic and/or sound cues improve a visually impaired user’s ability to navigate a room or building with or without occlusion.
Social implications
The application may prove useful for greater real world engagement: to build confidence in real world experiences, enabling persons with sight impairment to more comfortably and readily explore and interact with environments formerly unfamiliar or unattainable to them.
Originality/value
VirtuNav is developed as a practical application offering several unique features including map design, semi-automatic 3D map reconstruction and object classification from 2D map data. Visual and haptic rendering of real-time 3D map navigation are provided as well as automated administrative functions for shortest path determination, actual path comparison, and performance indicator assessment: exploration time taken and collision data.

Abstract
This chapter aims to rethink how gender inequality is related to interpersonal and structural asymmetries of power displayed in our relationships with ecosystems, questioning the classical concept of ‘nature’ as something ‘out there’, as pointed out by dark ecology. First, with the aim of offering a joint North–South critical perspective on equality and sustainability, critical ecofeminism, through the work of A. Puleo, will be explained as a Spanish feminist line of thought and movement. This author, rejecting some essentialist visions of deep ecology, sets her ideas in relation to general critical social theory. Second, contrasting perspectives (critical feminism and ecology) will be combined to offer a rich cross-fertilisation between different perspectives and traditional themes in criminology. A common denominator can be found in the exercise of criticism through questioning binary categories, underlying assumptions and social injustice in relation to the visibility of harms. Third, the relevance of ecofeminism for current criminological debates will be highlighted beyond the obvious connections with green victimology. Finally, ecofeminism will be interpreted as a new critical standpoint and as a more inclusive language for fostering the criminological and victimological imagination in order to help to rethink the rules of the criminal justice system.

Abstract
Purpose
People who inject drugs (PWID) face multiple health problems, including infectious diseases and drug overdoses. Applying syndemic and risk environment frameworks, this paper aims to examine the co-occurrence and clustering of drug-related harms and their association with incarceration experience with or without in-prison drug injection.
Design/methodology/approach
The authors used data from a cross-sectional survey conducted in 2015 among 557 active opioid injectors. Self-reported data were collected through face-to-face or online questionnaires. They distinguished three harm categories, namely, viral infections, bacterial infections and overdoses, and built an index variable by summing the number of harm categories experienced, yielding a score from 0 to 3. Association between incarceration experience and co-occurrence of harms was modelled using a multinomial logistic regression.
Findings
Of the 557 participants, 30% reported lifetime experience of drug-related viral infection, 46% bacterial infection and 22% drug overdose. Multinomial logistic models showed that those who injected drugs during incarceration were more likely to report two (aOR = 2.35, 95% CI: 1.03–5.36) and three (aOR = 9.72, 95% CI: 3.23–29.22) harm categories than those who had never been incarcerated. They were also more likely to report three harm categories than formerly incarcerated respondents who did not inject drugs in prison (aOR = 5.14, 95% CI: 1.71–15.48).
Originality/value
This study provides insights of the syndemic nature of drug-related harms and highlights that drug injection during incarceration is associated with co-occurring harms. Public health interventions and policy changes are needed to limit the deleterious impact of prison on PWID.

Abstract
Purpose
The purpose of this study is to examine the relationship between trade, foreign direct investment (FDI) and income inequality for Commonwealth of Independent States (CIS), using annual data from 1990 to 2016. The study attempts to answer a critical question: does openness affect income distribution?
Design/methodology/approach
The analysis of the model involves the examination of likely non-linear effects of both trade and FDI on income distribution. Therefore, system-generalized method of moments (SYS-GMM) estimator was applied to mitigate the problem of non-linearity and possible endogeneity. In the second stage, the model was extended to test the impact of education on income inequality. The hypothesis is that secondary school enrollment speeds up the process of adoption of contemporary technology and decreases inequality.
Findings
Trade and FDI have significant effects on income inequality when interacted with Gini-index; in case of trade, an inverted U-shaped curve holds as purposed by the trade theory. The components-wise effect of trade was held, except imports from advanced countries was found insignificant. Moreover, results were not found significant in case of human development index. Different results were found when trade and FDI interacted with education, which represents an important channel through which inequality is affected.
Research limitations/implications
The study implies that CIS needs to re-design trade and FDI policies by encouraging trade and FDI inflows into industries and sectors aligned with structural adjustments, domestic industries uplift and investment in social infrastructure.
Originality/value
This is the first study that has examined the impact of openness of income distribution in case of CIS.
