Casey Hardison was arrested in spring 2004 for the production of psychedelictype drugs ie. LSD, 2C‐B and DMT. In the three years since, not one person from ‘authority’ had bothered to ask him what motivated him to synthesise psychedelic drugs. It was as if the a priori assumption that ‘all illegal drugs are bad’ had provided the answer. Hence, the Judge asserted that Hardison did it for ‘that basest of human emotion, greed’ as though the psychospiritual benefits of an alchemical path dedicated to expanding consciousness and personal transformation, through insights integrated into action, upon which he had expounded at great lengths during trial, were some elaborate ‘portmanteau defence’, just some ruse to get him out of the dock. It was not, it was a committed stand for ‘cognitive liberty’ and for a world full of people who understand the fine line between alone and all one.

This paper aims to propose a service-oriented framework for performing content annotation and search, adapted to the task context. Media production workflows are becoming increasingly distributed and heterogeneous.The tasks of professionals in media production can be supported by automatic content analysis and search and retrieval services.

The processes of the framework are derived top-down, starting from business goals and scenarios in audiovisual media production. Formal models of tasks in the production workflow are defined, and business processes are derived from the task models. A software framework enabling the orchestrated execution of these models is developed.

This paper presents a framework that implements the proposed approach called Metadata Production Management Framework (MPMF). The authors show how a media production workflow for a real-world scenario is implemented using the MPMF.

The authors have demonstrated the feasibility of a model-based approach for media processing. In the reification step, there is still information that needs to be provided in addition to the task models to obtain executable processes. Future research should target the further automation of this process.

By means of this approach, the implementation of the business process defines the workflow, whereas the services that are actually used are defined by the configuration. Thus, the processes are stable and, at the same time, the services can be managed very flexibly. If necessary, service implementations can also be completely replaced by others without changing the business process implementation.

The authors introduce a model-based approach to media processing and define a reification process from business-driven task models to executable workflows. This enables a more task-oriented design of media processing workflows and adaptive use of automatic information extraction tools.

Trading illicit drugs on cryptomarkets differs in many ways from material retail markets. This paper aims to contribute to existing studies on pricing by studying the relationship between price changes in relation to changes in nominal value of the cryptocurrency. To this, the authors qualitatively study product descriptions and images to expand the knowledge on price formation.

The authors analysed 15 samples based on visual and textual scrapes from two major drug markets – for Dream Market between January 2014 and July 2015 and for Tochka between January 2015 and July 2015. This longitudinal study relates changes in process to variations in the Bitcoin exchange rate and selling strategies. The analysis of the marketing of drugs online also addressed the development of the vendor profile and product offers.

Product prices change in relation to variations in the Bitcoin exchange rate. This points to the application of mechanisms for automatic price adaptations on the market level. Real prices of the drug offers constantly increase. The authors assert that there is a bidirectional relationship. Vendors structure price and discounts to encourage feedback. And feedback in combination with signals of commitment and authenticity inform pricing. Product descriptions are an important feature in the successful marketization of goods, whereas product images are predominantly used as an aspect of recognisability and feature of the vendor’s identity.

Findings suggest that there is great potential for further qualitative research into the relationship between the online and offline identity of drug vendors, as well as price setting when entering the market and subsequent changes for offered products.

Findings also suggest that further investigation into the constitution and management of vendor’s identity on the cryptomarkets would allow a better understanding of vendors and their interactions on cryptomarkets.

A better understanding of drug trading on cryptomarkets helps to more effectively address potentials for harm in the online drug trade. Also targetting crime would benefit from a better understanding of vendor idenities and pricing.

The findings represent a valuable contribution to existing knowledge on drug trading on cryptomarkets, particularly in view of pricing and vending strategies.

In this paper, I synthesize the prior psychology literature on ego depletion and apply this literature to an auditing setting. Ego depletion refers to a reduced desire or ability to use self-control in task performance due to using self-control on prior tasks. I focus on the likely causes and consequences of depletion in an auditing setting, as well as means of mitigating depletion and recovering self-control resources. While ego depletion theory is prevalent in the psychology literature, little is known about whether or how ego depletion affects professionals on meaningful task performance. As a result, this synthesis is aimed at stimulating future ego depletion research in accounting, and specifically auditing, by surveying existing literature and applying this literature to an auditing setting. Further, I develop 13 questions for future research to investigate. My synthesis reveals that ego depletion likely has a pervasive effect in an auditing setting, and can hinder auditors’ judgment and decision-making (JDM) quality. Therefore, this synthesis helps to provide a greater understanding of the impact of auditing tasks on individuals, and refines both auditor JDM and ego depletion theories.

Although the organizational identity (OI) construct (Albert & Whetten, 1985) is now in its fourth decade, research in the field has been somewhat uneven, particularly with respect to an essentialist view and hypothetico-deductive type of studies. Believing that this stems in large part from insufficient construct clarity (Suddaby, 2010), this theory-development initiative presents an expanded conceptual framework. The authors exploit several key elements of individual identity and make the case for using these as the basis for conceptualizing an organizational-level equivalent. Starting with the premise that an individual’s identity is the product of comparisons, two dimensions are identified: the type of comparison (similarity, difference), referred to as the “identity conundrum,” and the object of comparison (self–other, self–self), referred to as the “identity perspective.” The authors then propose a four-cell distinctive conceptual domain for OI and explore its implications for scholarship.

The resource-based view of the firm and strategic groups research are two of the most investigated frameworks in strategic management. Historically, assumptions behind these two views have seemingly put them at odds. The resource-based view of the firm argues that sustained competitive advantage is best attained when firms have unique resources, while strategic groups research argues that a number of firms within the same industry can achieve sustained profitability with strategies that are similar to one another, but distinct from other industry members. The two views focus on different levels of analysis and each largely ignores the other’s focal level. Yet neither offers any propositions that are incompatible with the tenets of the other. Thus, conceptual integration that crosses levels of analysis is possible and potentially fruitful. Indeed, some strategic groups research has begun to bridge the gap between these two theories by suggesting that firm differences exist both within and between strategic groups. This article adopts a multi-level view by developing propositions concerning contingencies when firm differences, group processes, or both may lead to sustained competitive advantage. Implications for practitioners as well as suggestions for future theory building and empirical tests are also discussed.

Previous studies have highlighted that communication barrier was one of the major safety problems faced by ethnic minority (EM) workers. This study aims to model the predominant safety communication networks of EM crews and explore the relationships among safety communication networks, individual attributes, safety climate, near misses and injuries of EM crews.

Case studies were conducted with EM crews in the Hong Kong construction industry. Demographic attribute, network, safety climate and accidents data were collected through questionnaires and analyzed by a combination of social network analysis (SNA), cross-case comparison and nonparametric tests.

The results revealed that language proficiency, network density and level of reciprocity were contributing factors of distinguishing high and low safety performing EM crews. EM management received more safety information from EM workers than local management. The centrality of EM workers was significantly related to their age, the perceived priority of safety and language ability.

The research findings regarding the impact of safety communication network characteristics on the safety performance of EM crews provides insights to employers on how to cultivate effective safety communication patterns within EM crews that can lead to better safety performance. The connections between personal attributes and their positions in safety communication networks could help the employers identify the EM workers who are positioned on edges of networks and need more attention.

This study contributes to knowledge by enriching the limited research on analyzing safety communication of small construction crews using SNA and expanding the research object to EM construction crews in the literature, who are more vulnerable to construction accidents. This research also extends the existing body of knowledge from studies mainly carried out in Western culture to Eastern culture. Although safety communication has been regarded as important for EM workers, there is a lack of quantitative analysis on this at a crew level. The present study provides empirical research to reveal authentic safety communication networks and their connections with safety performance and personal attributes.
