The purpose of this paper is to report the effect of sputtering time on the electrical and physical properties of ZrO_x. ZrO_x (measured thickness is ranging from 20.5 to 51.3 nm) thin films as gate oxide materials are formed by metal deposition at different sputtering time and thermal oxidation techniques.

Zirconium is deposited on silicon substrate at three different sputtering time; 30‐, 60‐ and 120‐s continued with an oxidation process conducted at 500°C for 15 min to form ZrO_x thin films. High‐resolution X‐ray diffraction (HR‐XRD), Fourier transform infrared (FTIR) spectroscopy and electrical characterizations were used to examine the properties of the thin film.

A broad ZrO_x peak lies in between 26° and 31° from HR‐XRD is presumed as the effect of small thickness of ZrO_x and or the ZrO_x is still partially crystalline. FTIR spectroscopy results suggested that besides ZrO_x, SiO_x interfacial layer (IL) has also formed in all of the investigated samples. As the sputtering time increases, hysteresis between the forward and reverse bias of capacitance‐voltage curve has reduced. The lowest leakage current density and the highest oxide breakdown voltage have been demonstrated by 60‐s sputtered sample. These may be attributed to a lower effective oxide charge and interface trap density. The extracted dielectric constant (κ) of these oxides is ranging from 9.4 to 18, in which the κ value increases with the increase in sputtering time.

ZrO_x thin film which was fabricated by sputtering method at different sputtering time and thermal oxidation techniques showed distinctive electrical results. SiO_x IL formed in the samples.

The 3,4-methylenedioxymetamphetamine (MDMA) content in ecstasy tablets has increased enormously throughout Europe across the past decade. This study aims to determine whether this is caused by the production of “stronger” tablets (more mg MDMA per mg of tablet), or if tablets have simply been getting larger and heavier (more mg of tablet in total).

A data set of 31,716 ecstasy tablets obtained in 2012–2021 by 10 members of the Trans European Drug Information (TEDI) network was analysed.

The MDMA mass fraction in ecstasy tablets has remained virtually unchanged over the past 10 years, with increased MDMA contents being attributed almost exclusively to increased tablet weight. These trends seem to be uniform across Europe, despite varying sampling and analytical techniques being used by the TEDI participants. The study also shows that while tablet weight correlates perfectly with MDMA content on a yearly basis, wide variations in the MDMA mass fraction make such relations irrelevant for determining the MDMA content of individual tablets.

These results provide new opportunities for harm reduction, given that size is a tangible and apparently accurate characteristic to emphasise that one tablet does not simply equate to one dose. This is particularly useful for harm reduction services without the resources for in-house quantification of large numbers of ecstasy tablets, although the results of this study also show that chemical analysis remains crucial for accurate personalised harm reduction.

The findings are both new and pertinent, providing a novel insight into the market dynamics of ecstasy tablet production at a transnational level.

The purpose of this paper is to present some of the continued resistance and challenges faced by drug checking services (DCS) and review how the existing literature and the contributions to the special issue address them, with a view to making recommendations.

The existing literature and the contributions to the special issue are reviewed.

Drug checking cannot be equated with quality control. With the appropriate equipment and chemistry staff, DCS can provide quantitative analysis and reliable results. When the product does not match expectations, service users discard the tested substance of concern. To more easily compare the results of different studies and better evaluate drug checking, standardisation of measures is desirable. Uptake of drug checking, notably in festivals, is low and depends in part on the capacity of DCS. Drug checking has added value in monitoring drug markets and is complementary with chemical (forensic) analysis.

This paper interrogates in a relatively comprehensive way the continued resistance to drug checking in light of theoretical and empirical research to derive recommendations that are specific to drug checking and that are addressed to health professionals, researchers and also to policymakers.

Global/national policy planning is guided by economic methods and predictions of growth, where indicators of success are measured according to a dominant view of progress and sustainable development. Yet, despite widespread ratification of the Declaration on the Rights of Indigenous Peoples, Indigenous Peoples remain unrepresented in this dominant view. The structural and historical forces informing global policy thus inadvertently produce a pathway of development that is characterized by political, economic, and social exclusion where Indigenous Peoples’ agency, heritage, and culture remain marginalized. I argue that socio-cultural nuance (“the complete story”) is critical to policy planning if we are to honor the principal aim of the Sustainable Development Goals – “leave no-one behind”. This and other policy frameworks need an approach that is neither framed by Eurocentric objectives nor bound by measurable indicators. This requires consideration of Indigenous Worldviews in a way that mediates diverse social, economic, and political factors. In this chapter, I examine the limitations in current policy consultation practice, with a specific focus on the extractive industries sector, and examine the ways in which engagement with Indigenous Peoples’ “complete story” might inform policy in the pursuit of a sustainable development that leaves no-one behind and creates a bridge between dominant and marginalized forms of knowledge.

The recent influx of interest in and the changing status of drug checking has led us to reconsider some fundamental questions about drug checking. This commentary aims to define drug checking. It proceeds in three parts: terminology, definitions and programmes that are excluded from the definition of drug checking that still have value for harm reduction.

To inform the commentary, an informal review of pertinent publications on the topic was conducted to extract relevant definitions and terminology.

Drug checking services (DCS) have five necessary features: (1) aim of reducing harm; (2) analyse samples directly from the public; (3) return results to the service user; (4) involve information exchange between service user and DCS; and (5) conduct a tailored intervention with the service user. Variable features include the populations served, setting, analysis methods, immediacy of results, nature of intervention, levels of engagement with other stakeholder groups, funding models, legal status and staff skillsets. Programmes that are not DCS but have some similarities to DCS include non-publicly accessible testing of drugs as well as testing of bodily fluids where results may inform drug alerts.

Drug checking remains a legally, politically and commercially sensitive health service. Reflecting on the history and evolution of drug checking, both as a term and as a harm reduction service, helps provide clarity in terms of what drug checking is and what it is not. This facilitates more effective framing of evaluations, in terms of what DCS aim to do and achieve.

The purpose of this paper is to explore economic conditions of contemporary society to provide insight into the ways in which the consequences of disaster, including environmental migration, are accentuated.

This research draws on Zygmunt Bauman’s theory of liquid modernity and notions of development to analyse disaster. From the analysis, a new concept, liquid development, is proposed and critiqued as a contributing factor leading to severe contemporary disaster.

Liquid development provides a new way of making sense of the conditions and consequences of economic growth and a business as usual attitude. It further provides a framework to explore the potential disaster of environmental migration in the Pacific Islands arising from liquid development driven climate change-induced sea level rise.

Analysing these conditions provides greater understanding of the resulting impact of disaster, creating awareness and informing the need for accountability and social policy. This study aims to contribute to further practical and research enquiry that will challenge liquid developers to reconsider their impact and to accept responsibility for vulnerable members of society as part of their business as usual structure.

This paper adds to Bauman’s understanding of the consequences of globalisation through the construct of liquid development. It also continues his debate by giving awareness to the global issue of environmental migration.

While there is increasing interest in implementing drug checking within overdose prevention, we must also consider how to scale-up these responses so that they have significant reach and impact for people navigating the unpredictable and increasingly complex drug supplies linked to overdose. The purpose of this paper is to present a distributed model of community drug checking that addresses multiple barriers to increasing the reach of drug checking as a response to the illicit drug overdose crisis.

A detailed description of the key components of a distributed model of community drug checking is provided. This includes an integrated software platform that links a multi-instrument, multi-site service design with online service options, a foundational database that provides storage and reporting functions and a community of practice to facilitate engagement and capacity building.

The distributed model diminishes the need for technicians at multiple sites while still providing point-of-care results with local harm reduction engagement and access to confirmatory testing online and in localized reporting. It also reduces the need for training in the technical components of drug checking (e.g. interpreting spectra) for harm reduction workers. Moreover, its real-time reporting capability keeps communities informed about the crisis. Sites are additionally supported by a community of practice.

This paper presents innovations in drug checking technologies and service design that attempt to overcome current financial and technical barriers towards scaling-up services to a more equitable and impactful level and effectively linking multiple urban and rural communities to report concentration levels for substances most linked to overdose.

The purpose of this paper is to compare supply network strategies of district firms (from now on ID) and non‐district (non‐ID) firms with the aim of outlining emerging strategies as well as identifying similarities and differences between business models.

The analysis is based on a quantitative approach: the TeDIS survey focuses on 45 leading Italian districts and SMEs located outside districts (Made in Italy sectors). Results refer to 630 Italian firms.

There are more similarities than differences between the approach of ID and non‐ID companies to supply networks. ID firms rely more on local systems in terms of supply networks, while non‐ID firms have also invested at national level (subcontracting networks). The global geographical extension of supply networks stresses the ID companies' search for efficiency in addition to value‐added competences. Non‐ID firms have a more hierarchical approach to internationalization than ID firms, but differences decrease as the size of the companies increases.

The study is still preliminary. Future research should explore the relationships between the strategic approach to supply networks of district firms and non‐ID firms in terms of characteristics of the relationship management and aims of relationships, also with a focus on the size of these firms.

Within the existing literature, the original contribution of the paper lies in its comparison of supply network strategies in ID and non‐ID firms based on a significant quantitative analysis.
