Drug cryptomarkets increase information available to market actors, which should reduce information asymmetry and increase market efficiency. This study aims to determine whether cryptomarket listings accurately represent the advertised substance, weight or number and purity, and whether there are differences in products purchased from the same listing multiple times.

Law enforcement drug purchases – predominantly cocaine, methamphetamine, MDMA and heroin – from Australian cryptomarket vendors (n = 38 in 2016/2017) were chemically analysed and matched with cryptomarket listings (n = 23). Descriptive and comparative analyses were conducted.

Almost all samples contained the advertised substance. In most of these cases, drugs were either supplied as-advertised-weight or number, or overweight or number. All listings that quantified purity overestimated the actual purity. There was no consistent relationship between advertised purity terms and actual purity. Across the six listings purchased from multiple times, repeat purchases from the same listing varied in purity, sometimes drastically, with wide variation detected on listings purchased from only one month apart.

In this data set, cryptomarket listings were mostly accurate, but the system was far from perfect, with purity overestimated. A newer, larger, globally representative sample should be obtained to test the applicability of these findings to currently operating cryptomarkets.

This paper reports on the largest data set of forensic analysis of drug samples obtained from cryptomarkets, where data about advertised drug strength/dose were obtained.

Past research has demonstrated a health halo for food product labels (e.g. organic), resulting in inflated perceptions of a product’s healthfulness (e.g. low fat). While past studies have focused on labeling and related health claims, the health halo of brand names has scarcely been investigated. This study aims to address this gap by investigating the health halo of brand names featuring morality- and purity-signifiers.

The current research uses two experiments to examine the health halo of morality- and purity-signifying brand names on perceptions of nutritional and contaminant attributes. Mediation analysis is performed to investigate perceived naturalness as the mechanism for the brand name effects while moderated mediation analysis examines this mechanism across product types (healthy vs unhealthy).

The findings reveal that both the morality- and purity-signifying brand names produce a health halo on nutritional and contaminant attributes, regardless of product healthiness. Further, mediation and moderated mediation analysis provide evidence for perceived naturalness as the underlying mechanism driving these effects.

This research highlights unwarranted consumer inferences made based upon food brand names and, thus has implications for consumers, public policy and marketing managers.

While much health halo research has focused on labeling, this research examines the health halo of two brand name types which symbolically convey either morality or purity. This research provides additional contributions by investigating perceived naturalness as the underlying mechanism for the effects and is one of the few studies to investigate the health halo for both healthy and unhealthy products.

The “categorization as a theoretical tool” framework is delineated to clarify how innovation is possible even though candidates for exchange face a “categorical imperative” – pressure from their audience to adopt the conventional practices associated with existing categories. The key insight is that categorization is generally a useful tool for sorting and screening exchange opportunities. This insight is developed to suggest how the nature of the imperative varies with the audience’s objectives and the theory of value it espouses and how the strength of the imperative varies with the social challenges and opportunities for engaging in, and learning from, experiments with unconventionality.

Professionals often dislike dirty work, yet they accommodate or even embrace it in everyday practice. This chapter problematizes Andrew Abbott’s professional purity thesis by examining five major forms of impurities in professional work, namely impurity in expertise, impurity in jurisdictions, impurity in clients, impurity in organizations, and impurity in politics. These impurities complicate the relationship between purity and status as some impurities may enhance professional status while others may jeopardize it, especially when the social origins of professionals are rapidly diversifying and professional work is increasingly intertwined with the logics of market and bureaucracy. Taking impurities seriously can help the sociology of professions move beyond the idealistic image of an independent, disinterested professional detached from human emotions, turf battles, client influence, and organizational or political forces and towards a more pragmatic understanding of professional work, expertise, ethics and the nature of professionalism.

Using the canvas of the author’s sojourn with the Islamic preaching group Tablighi Jamaat, this study aims to exhibit reflections on how spaces can be categorized as more sacred or less sacred according to a specific religious worldview. The paper extends the conversation on Mary Douglas’s concepts of purity and danger by sharpening the focal lens on place in Douglas’s theoretics. The paper also proffers the idea of a sojourn as a vehicle of purification.

This paper depicts findings from the author’s multi-sited ethnographic field notes carried out from a 40-day sojourn with the Islamic preaching group Tablighi Jamaat in Pakistan.

The study unveils the concept of relative sacredness or how some spaces can be considered more sacred than others. The differential sacred status of these variegated spaces, each with its own etiquettes, meaning and consumption rituals is a means for purification for sojourners.

This paper prioritizes a focus on place in Mary Douglas’s arguments on purity and impurity in a religious consumption context. The thesis argues that place is a significant concept associated with metaphorical cleanliness/sacredness, which in religious terms guides consumer action.

This paper aims to deal with the effect of natural barytes purity levels on the tribological performance of brake pads.

In this study, brake pads were developed by varying three different natural barytes without varying other ingredients. The brake pads were developed as per the standard industrial practice. The physical, mechanical and thermal properties of the developed brake pads were tested as per the industrial standards. The tribological properties were analyzed using a full-scale inertia brake dynamometer. Worn surface analysis was done using scanning electron microscope coupled with elemental mapping.

The experimental results indicate that the brake pads filled with natural barytes 95% purity had good physical, chemical and mechanical properties with stable friction and less wear rate due to reduced impurity level preventing frictional undulations.

This paper explains the effect of the purity level of natural barytes in brake pads formulation to enhance the tribological performance by altering tribofilms and preventing friction undulations.

In view of the current difficulty of separation of troxerutin, the purpose of the paper is to separate and purify semi-synthetic flavonoid compound troxerutin by macroporous adsorption resin (SZ-3).

Comparing the adsorption performance and resolution of three different polar resins and choosing a resin to optimize the process parameters such as sample volume, eluent concentration and elution temperature to obtain high-purity troxerutin. After separating and enriching by resin column chromatography, detected the sample by LC-MS analysis.

This research found that the optimal conditions of the adsorption and desorption were sample volume S = 90 mg/g resin, methanol concentration C = 25%, T = 20 °C. the content of troxerutin increased significantly from 88% to more than 96%. Then confirmed the sample was troxerutin by LC-MS. In addition, the resin could be used for at least 10 cycles in the separation and purification experiments of troxerutin.

Purification of troxerutin with new SZ-3 resin for the first time. Under the optimal conditions, the purity and recovery of troxerutin was 96.4% and 39%. In this study, the authors established a purification process of troxerutin successfully that was simple, economical, environment friendly, with high purity and high recovery rate to provide a reference program for changing the status of troxerutin separation difficulties.

Purpose: This paper examines beef consumption practices in two villages of Tamil Nadu, India. It inquires into how the upper castes create spatial boundaries to separate the inside from the outside in their consumption of beef.

Methodology: The research was carried out in two villages of Kariacheri and Pudupattinam located in the Kanchipuram district of Tamil Nadu, India. We conducted 70 in-depth interviews, and observed beef buying and consumption practices.

Findings: The research shows how the upper castes separate the inside from the outside and surreptitiously consume beef. Dalits or untouchables are unable to create such separations, and as a result are stigmatized and ostracized. Moreover, the distinction between the inside and the outside is not fixed but is in a state of transition.

Originality and value: This study offers insights into how stigma is defined by spatial boundaries. These insights help to understand purity, pollution, and stigma in consumption practices as ongoing processes that are often created to justify social divisions and discriminatory practices.

This paper aims to discuss the influence of graphite with varying purity on the tribological performance of brake pads.

Three distinct brake pads were created within the scope of this experiment by varying the graphite purity without affecting the other components. The brake pads were made using a traditional manufacturing procedure, and industry standards were used to test the chemical, physical and mechanical properties of the newly produced brake pad. A full-scale inertia brake dynamometer was used to determine the material’s tribological characteristics. The worn surfaces of the brake pads were examined using a scanning electron microscope.

The test results indicate that brake pads containing 99% pure graphite (artificial grade) displayed good physical, chemical and mechanical features, such as consistent friction and a reduced rate of wear because of the lower impurity level, which eliminates frictional undulations.

This paper discusses the influence of graphite purity on the tribological performance of brake pads by modifying tribofilms and reducing friction undulations.

The purpose of this study is to investigate the environmental conditions (i.e. competitive intensity) under which a pure strategy or an ambidextrous strategy of implementing responsive market orientations (RMOs) and/or proactive market orientations (PMOs) is more advantageous for firm’s performance.

Drawing upon the market orientation (MO) and strategy literatures, the authors test the study’s model empirically using a sample of 308 US-based firms operating in industrial markets. All measurement items are taken from the widely used maturity scale which has been confirmed in the literature.

The empirical results suggest that when the competitive intensity is high, pursuing a purity strategy of RMO while decreasing PMO is the best course of action. On the other hand, balancing between RMO and PMO (implementing a strategy of ambidexterity) can increase firm’s performance in a low competitive intensity environment.

This study aims to contribute to the existing MO literature in several ways: first, this study advances the MO literature by emphasizing the moderating role of competitive intensity on the effects of different MO strategies (purity or ambidextrous MO strategy); second, this study focuses on the firms operating in industrial markets and informs managers on how to adopt RMO and PMO under different level of competitive intensity; third, this study is the extended research of the prior study published in this journal (Wang et al., 2013), which examined the environmental antecedents of adopting RMO and PMO.

First, firms operating in industrial markets should increase RMO, while at the same time decrease PMO, in a highly competitive intensity environment. Second, companies should pursue both RMO and PMO at the same time in a low competitive intensity environment. Balancing between RMO and PMO can improve firms’ performance in a low competitive intensity environment.

This study contributes to the industrial business and marketing literature by sharpening the theoretical understanding of the impact of RMOs and PMOs on firm’s performance. It also offers practical insights to managers of industrial firms on when to adopt RMOs and/or PMOs under different levels of competitive intensity.
