Legal Systems in Transformation and Transnational Conflict Solution in Information Society
Technological development has revolutionized many human activities, turning the world into a global society, an information society. In this new context, the new information and communication technologies are seen as indispensable support in all areas of human knowledge. Following this new pattern, a new legal dimension has emerged which challenges the State, its essential elements and its geographical boundaries. The public law concepts of sovereignty and jurisdiction along with the criminal law concepts of enforcement and jurisdiction have experienced remarkable changes due to the changing idea of time and space as to when and where a crime is committed. Considering the transnational character due to the globalization of the juridical process, some modifications have been made in the approach to the term sovereignty. Even though its concept and characteristics may involve many interpretations of doctrinal order, without consensus, the result of these interpretations, in many cases, come to delimit the debate which is set in a globalized juridical perspective
[Accepted Manuscript] Smartphone tool to collect repeated 24 h dietary recall data in Nepal.
To outline the development of a smartphone-based tool to collect thrice-repeated 24 h dietary recall data in rural Nepal, and to describe energy intakes, common errors and researchers' experiences using the tool.
We designed a novel tool to collect multi-pass 24 h dietary recalls in rural Nepal by combining the use of a CommCare questionnaire on smartphones, a paper form, a QR (quick response)-coded list of foods and a photographic atlas of portion sizes. Twenty interviewers collected dietary data on three non-consecutive days per respondent, with three respondents per household. Intakes were converted into nutrients using databases on nutritional composition of foods, recipes and portion sizes.
Dhanusha and Mahottari districts, Nepal.
Pregnant women, their mothers-in-law and male household heads. Energy intakes assessed in 150 households; data corrections and our experiences reported from 805 households and 6765 individual recalls.
Dietary intake estimates gave plausible values, with male household heads appearing to have higher energy intakes (median (25th-75th centile): 12 079 (9293-14 108) kJ/d) than female members (8979 (7234-11 042) kJ/d for pregnant women). Manual editing of data was required when interviewers mistook portions for food codes and for coding items not on the food list. Smartphones enabled quick monitoring of data and interviewer performance, but we initially faced technical challenges with CommCare forms crashing.
With sufficient time dedicated to development and pre-testing, this novel smartphone-based tool provides a useful method to collect data. Future work is needed to further validate this tool and adapt it for other contexts

Trends in gabapentinoid prescribing in UK primary care using the Clinical Practice Research Datalink: an observational study
Background
The UK government reclassified gabapentin and pregabalin as ‘controlled drugs’ from April 2019. This study aimed to describe the trends in gabapentinoid prescribing before and immediately after reclassification, in the UK Clinical Practice Research Datalink, an electronic primary care health record broadly representative of the UK.
Methods
Separately for gabapentin and pregabalin, we calculated annual incident and prevalent prescribing rates from year of UK approval (April 1997 and 2004 respectively) to September 2019, and monthly incident and prevalent prescribing rates (October 2017–September 2019). Significant changes in temporal trends were determined using joinpoint regression. We also described potential prescribing indications, prior pain-related prescribing, and co-prescribing with potentially interacting medicines.
Findings
Incident gabapentin prescribing increased annually, peaking in 2016–17, at 625/100,000 patient years before falling steadily to 2019. Incident pregabalin prescribing peaked at 329/100,000 patient years in 2017–18 and did not fall significantly until 2019. Prevalent gabapentin and pregabalin prescribing increased annually to 2017–18 and 2018–19 respectively, before plateauing. Gabapentinoids were commonly co-prescribed with opioids (60%), antidepressants (52%), benzodiazepines (19%), and Z-drugs (10%).
Interpretation
Following a dramatic rise, incident gabapentinoid prescribing has started to fall but the specific impact of reclassification on prescribing rates remains unclear. Limited change in prevalent gabapentinoid prescribing during the 6 months following their reclassification as controlled drugs suggests little immediate impact on continued gabapentinoid prescribing for existing users.

Drug-Initiated Synthesis of Cladribine-Based Polymer Prodrug Nanoparticles: Biological Evaluation and Structure Activity Relationships
International audienceBy using two reversible deactivation radical polymerization techniques, either nitroxide-mediated polymerization or reversible addition-fragmentation chain transfer polymerization, the "drug-initiated" approach was applied to cladribine (CdA) as an anticancer drug to synthesize small libraries of well-defined and self-stabilized CdA-based polymer prodrug nanoparticles, differing from the nature and the molar mass of the grown polymer, and the nature of the linker between CdA and the polymer, thus allowing structure-cytotoxicity relationships to be determined. Their biological evaluation was investigated in vitro on L1210 cancer cells. The preparation of fluorescent CdA-based nanoparticles with excellent imaging ability was also reported by applying the "drug-initiated" approach to an aggregation-induced emission-active dye
The Pub and the People. A Worktown Study by Mass Observation.
Mass Observation was an independent social research organization which, between 1937 and 1949, documented the attitudes, opinions and everyday lives of the British people, using a combination of anthropological fieldwork, opinion surveys and written testimony. The Pub and the People is a classic text for its distinctly sociological approach, seeing patterns of drinking and socializing in context, rather than focusing primarily on pathological consequences. The main conclusions were that the pub is a living social organism and that the traditional approach of British sociology which, Mass Observation argued, focused on 'the drink problem' and the links between alcohol, crime and delinquency, failed to take account of the full social context. Mass Observation's focus on the pub as a place anticipates themes taken up in work on alcohol in cultural geography. Later alcohol researchers and epidemiologists have continued this orientation, recognizing the importance of physical and social environments in relation to alcohol consumption. Other studies have built on the MO initiative by looking at how drug and alcohol consumption links to identity, friendship and sociality or at the connections between intoxication and pleasure. The value of this classic text is that it reminds us that paying attention to the social context is not just a useful supplement, but absolutely central to understanding the use of alcohol or drugs

Participatory Women's Groups with Cash Transfers Can Increase Dietary Diversity and Micronutrient Adequacy during Pregnancy, whereas Women's Groups with Food Transfers Can Increase Equity in Intrahousehold Energy Allocation
Background:
There is scarce evidence on the impacts of food transfers, cash transfers, or women's groups on food sharing, dietary intakes, or nutrition during pregnancy, when nutritional needs are elevated. //
Objective:
This study measured the effects of 3 pregnancy-focused nutrition interventions on intrahousehold food allocation, dietary adequacy, and maternal nutritional status in Nepal. //
Methods:
Interventions tested in a cluster-randomized controlled trial (ISRCTN 75964374) were “Participatory Learning and Action” (PLA) monthly women's groups, PLA with transfers of 10 kg fortified flour (“Super Cereal”), and PLA plus transfers of 750 Nepalese rupees (∼US$7.5) to pregnant women. Control clusters received usual government services. Primary outcomes were Relative Dietary Energy Adequacy Ratios (RDEARs) between pregnant women and male household heads and pregnant women and their mothers-in-law. Diets were measured by repeated 24-h dietary recalls. //
Results:
Relative to control, RDEARs between pregnant women and their mothers-in-law were 12% higher in the PLA plus food arm (log-RDEAR coefficient = 0.12; 95% CI: 0.02, 0.21; P = 0.014), but 10% lower in the PLA-only arm between pregnant women and male household heads (−0.11; 95% CI: −0.19, −0.02; P = 0.020). In all interventions, pregnant women's energy intakes did not improve, but odds of pregnant women consuming iron-folate supplements were 2.5–4.6 times higher, odds of pregnant women consuming more animal-source foods than the household head were 1.7–2.4 times higher, and midupper arm circumference was higher relative to control. Dietary diversity was 0.4 food groups higher in the PLA plus cash arm than in the control arm. //
Conclusions:
All interventions improved maternal diets and nutritional status in pregnancy. PLA women's groups with food transfers increased equity in energy allocation, whereas PLA with cash improved dietary diversity. PLA alone improved diets, but effects were mixed. Scale-up of these interventions in marginalized populations is a policy option, but researchers should find ways to increase adherence to interventions.

Multidirectional Synthesis of Substituted Indazoles via Iridium-Catalyzed C–H Borylation
IUPAC recommended experimental methods and data evaluation procedures for the determination of radical copolymerization reactivity ratios from composition data
The IUPAC working group on “Experimental Methods and Data Evaluation Procedures for the Determination of Radical Copolymerization Reactivity Ratios” recommends a robust method to determine reactivity ratios from copolymer composition data using the terminal model for copolymerization. The method is based on measuring conversion (X) and copolymer composition (F) of three or more copolymerization reactions at different initial monomer compositions (f0). Both low and high conversion experiments can be combined, or alternatively only low conversion experiments can be used. The method provides parameter estimates, but can also reveal deviations from the terminal model and the presence of systematic errors in the measurements. Special attention is given to error estimation in F and construction of the joint confidence interval for reactivity ratios. Previous experiments measuring f0 − F or f − X can also be analyzed with the IUPAC recommended method. The influence of systematic errors in the measurements on the reactivity ratio determinations is investigated, including ways to identify and mitigate such errors
