Driving sustainable uptake: a systematic review of global literature on policies governing woody biomass for energy
Authors: Pandey Spriha , Erbaugh James Thomas 
Published: March 2024

AbstractWoody biomass has gained increased attention as a source of renewable energy. However, its categorization as a sustainable source of energy remains controversial, as its carbon neutrality depends on its end use, moisture content, bulk density, and the distance between the source of biomass and its end use. Due to these mediating factors, policies largely shape its sustainability and ability to mitigate emissions. This paper organizes and evaluates the current state of research through a systematic review of global literature from 2011 to 2021 (n = 345) on the governance of the production, transportation, sale, and use of woody biomass for energy. Peer-reviewed literature emphasizes the role of woody biomass as a decentralized energy source for individual households and communities, focusing on its harvest, transport, and localized energy conversion. Policies primarily address land management and energy infrastructure rather than direct emissions reduction. Research gaps in policy within the Global South underscore the need to examine biomass regulation in regions with limited energy diversity. The key factors that drive the sustainable uptake of woody biomass include strict sustainability criteria, fiscal incentives, technological development, and wood utilization from across its value chain. Effective policy implementation increases rural employment, boosts rural economies, provides energy security to remote areas, improves overall environmental sustainability, reduces emissions, and improves land management practices. Our systematic review reveals that future research should focus on improving conversion efficiencies in small-scale systems, reducing emissions in the international trade of woody biomass, and using the wood value chain to increase the profitability of bioenergy products.

AbstractMore and more children and adolescents in Switzerland show serious deficits in their German language skills. In order to specifically promote the language skills of students with a non-German first language, special lessons in German as a second language (GasL) are therefore offered in addition to the regular lessons. The aim of this case study is to evaluate the impact of a pedagogically sound immersive virtual reality learning unit for GasL lessons, which offers students the opportunity to actively speak German and to demonstrate this in the context of two GasL lessons. The research design is based on the “Design Science Research Framework”. In this context, the virtual reality learning unit was designed as an innovative prototype (artifact) and iteratively improved. The design considered the didactic framework of the official curriculum as well as the eleven general design guidelines for virtual reality learning units in an educational context. The virtual reality learning unit was tested in a field experiment with five students each at an elementary school and at a secondary school. The students found the virtual reality learning unit as a whole attractive and motivating. But there are operational challenges and necessary prerequisites that have to be considered and created in order to pragmatically and sustainably integrate immersive virtual reality learning units into the existing GasL lessons.

Published: March 2024

AbstractAnalgesia and sedation are important treatment strategies in the intensive care unit (ICU). Due to the opioid crisis, opioid-sparing medications become the focus of clinical studies. Ketamine and its isomers (mainly esketamine) are intravenous anesthetics that possess sedative, analgesic, and anesthetic effects, which have recently attracted the attention of critical care physicians. However, the application of ketamine/esketamine in ICU is limited and inexperienced. Experts from the Critical Care Medicine Professional Committee of the Chinese Research Hospital Association drafted this consensus based on the current clinical evidence to provide recommendations for the application of ketamine/esketamine in different fields of critical care, including sepsis and septic shock, endotracheal intubation, neurocritical care, respiratory critical care, post cardiac surgery care, burn and depression in ICU. Meanwhile, this expert consensus also appeals for more high-quality clinical trials to facilitate more reasonable guidelines in this area.
Groups of Persons in the Proposed AI Act Amendments
Authors: Nikiforov Liubomir 
Published: March 2024

AbstractThis article explores the proposed amendments to the AI Act, which introduce the concept of “groups of persons”. The inclusion of this notion has the potential to broaden the traditional individual-centric approach in data protection. The analysis explores the context and the challenges posed by the rapid evolution of technology, with an emphasis on the role of artificial intelligence (AI) systems. It discusses both the potential benefits and challenges of recognising groups of people, including issues such as discrimination prevention, public trust and redress mechanisms. The analysis also identifies key challenges, including the lack of a clear definition for “group”, the difficulty in explaining AI architecture concerning groups and the need for well-defined redress mechanisms. The article also puts forward recommendations aimed at addressing these challenges in order to enhance the effectiveness and clarity of the proposed amendments.
Contesting the property paradigm amid ‘radical’ constitutional change: Living Rent and the Private Housing (Tenancies) (Scotland) Act 2016
Authors: Jordan Mark 
Published: March 2024

AbstractThis paper examines the interaction between ‘radical’ constitutional change, in the form of political devolution, and property systems in the UK, from the perspective of those at the margins of those systems. The paper adopts a property ‘from below’ approach and critically applies the theoretical framework developed by AJ van der Walt in Property in the Margins. In that book, van der Walt outlined how property systems frequently operate to resist democratic and constitutional change and transformation through the functioning of the property paradigm, which refers to a set of doctrinal, rhetorical, and logical assumptions and beliefs about the relative value and power of discrete property interests in law and in society. Building on van der Walt's work, this paper takes eviction, which represents the landlord's apex right, as a case study and considers how qualifications of that right have been reformed by the Private Housing (Tenancies) (Scotland) Act 2016. It is argued that while the strength of the property paradigm is apparent in both English and Scottish property systems, Living Rent, a national tenants’ union in Scotland, have organised tenants to effectively contest and, in some respects, displace the logic of the property paradigm during the reform process.
Tattoos embody autobiographical memories

Abstract
Autobiographical memories play a vital role in shaping personal identity. Therefore, individuals often use various methods like diaries and photographs to preserve precious memories. Tattoos also serve as a means of remembering, yet their role in autobiographical memory has received limited attention in research. To address this gap, we surveyed 161 adults (68.9 per cent female, M = 26.93, SD = 6.57) to explore the life events that motivated their tattoos and to examine their most significant memories. We then compared these findings with significant memories of 185 individuals without tattoos (80.0 per cent female, M = 31.26, SD = 15.34). The results showed that the majority of tattoos were inspired by unique life events, including specific events about personal growth, relationships, leisure activities, losses, or diseases. Even when not directly tied to specific events in life, tattoos still reflect autobiographical content, such as mottos, beliefs, and values. Furthermore, the most significant memories of younger tattooed individuals (20–24 years) tended to be more normative and less stressful compared to those of their non-tattooed counterparts in the same age group, though the nature of these memories varied. This difference was not found among older participants (30–54 years). Additionally, those without tattoos indicated to use specific objects and methods for preserving important events, suggesting tattoos are only one of several ways to reminisce. However, tattoos uniquely allow for the physical embodiment of autobiographical memories, indicating that engraving significant life events in the skin aids in reflecting on one's life story.
CHRONOLOGICAL STUDY OF COLLECTIVE BURIALS IN THE NORTHERN IBERIAN PLATEAU: ANALYSIS OF RADIOCARBON DATES ON HUMAN BONES FROM THE MEGALITHIC COMPLEX OF LA LORA (BURGOS, SPAIN)
Authors: Santa Cruz Angélica 
Published: March 2024

ABSTRACTThis paper offers a temporal analysis of the megalithic group of La Lora in the context of northern Iberian Plateau megalithism. For this purpose, 67 accelerator mass spectrometry radiocarbon (AMS 14C) dates were obtained on human bone from the minimum number of individuals recovered from nine tombs. This is the first systematic dating project carried out in this dolmen group and has enabled the chronology of the main funerary series to be updated. The results reveal that the actual funerary use dates mainly to the 4th millennium BC, although, as deduced from the archaeological material, some tombs were reused in later periods. Additionally, the significant architectural polymorphism of the group, consisting mainly of simple dolmens and large corridor tombs, suggested a temporal evolution to monumentality. However, the dating shows a more complex reality, since it is likely that the large tombs functioned as funerary pantheons during the 4th millennium BC, characterized by a cyclical and recurrent use. In contrast, the simpler structures were preferred to be of shorter use and restricted to the first half of the 4th millennium.

AbstractBackgroundAlthough suicide bereavement is associated with suicide and self-harm, evidence regarding mechanisms is lacking. We investigated whether depression and substance use (alcohol and/or other drugs) explain the association between partner suicide bereavement and suicide.MethodsLinkage of nationwide, longitudinal data from Denmark for the period 1980–2016 facilitated a comparison of 22 668 individuals exposed to bereavement by a partner's suicide with 913 402 individuals bereaved by a partner's death due to other causes. Using causal mediation models, we estimated the degree to which depression and substance use (considered separately) mediated the association between suicide bereavement and suicide.ResultsSuicide-bereaved partners were found to have a higher risk of suicide (HRadj = 1.59, 95% CI 1.36–1.86) and of depression (ORadj 1.16, 95% CI 1.09–1.25) when compared to other-bereaved partners, but a lower risk of substance use (ORadj 0.83; 95% CI 0.78–0.88). An increased risk of suicide was found among any bereaved individuals with a depression diagnosis recorded post-bereavement (ORadj 3.92, 95% CI 3.55–4.34). Mediation analysis revealed that depression mediated 2% (1.68%; 95% CI 0.23%–3.14%; p = 0.024) of the association between suicide bereavement and suicide in partners when using bereaved controls.ConclusionsDepression is a partial mediator of the association between suicide bereavement and suicide. Efforts to prevent and optimize the treatment of depression in suicide-bereaved people could reduce their suicide risk. Our findings might be conservative because we did not include cases of depression diagnosed in primary care. Further work is needed to understand this and other mediators.

RésuméNotre recherche visait à mettre en lumière les pratiques bientraitantes des préposées aux bénéficiaires en milieux d’hébergement pour aînés au Québec. L’objet de l’article est de faire ressortir la dichotomie entre les définitions de la bientraitance et son opérationnalisation. Dans la première partie, la notion de bientraitance dans le cadre de deux politiques gouvernementales québécoises est présentée. Ensuite, il est question du travail des préposées aux bénéficiaires en tant que vectrices de cette bientraitance dans la pratique. La troisième partie présente les résultats de notre recherche qui viennent soulever trois constats remettant en cause l’applicabilité des politiques publiques en cette matière : l’absence de reconnaissance d’un métier par définition bientraitant; les injonctions normatives à l’encontre du sens attribué à la bientraitance, et les obstacles organisationnels et sociopolitiques à la bientraitance. Ces constats sont réexaminés à la lumière des écrits dans la discussion, laquelle ouvre sur la notion de maltraitance organisationnelle.
Institutionalising global mining knowledge: the rise of engineering education in late Qing China, 1870–95
Authors: Chen Hailian 
Published: March 2024

AbstractThe history of mining education in late Qing China has received relatively little attention in scholarly literature. Through the lens of institutionalising global mining knowledge, this article addresses the following questions: How did the demand for expertise within the framework of mining bureaucracy evolve under the impact of Western imperialism? How did mining education enter scholarly discourse and become eventually institutionalised in the late Qing China? Drawing on evidence from the collections of Sheng Xuanhuai's archive series, it investigates two previously overlooked ‘failures’ of Sheng's mining-related enterprises, namely his earliest mining practices in Hubei in the 1870s and his proposal for establishing a mining school in Shandong in 1888–89. It then reconnects these efforts with the histories of Western learning, late Qing mining bureaucracy, the monetary crisis of that era, and the global recruitment of engineers despite a pronounced distrust of foreign expertise. It argues that these seemingly discrete efforts or ‘failures’ in fact paved the way for initiating China's first engineering university as well as other mining colleges in around 1895 and eventually led to the rise of engineering education before the entire educational system was transformed in China.

AbstractThe crystallographic preferred orientation (CPO) of olivine, specifically the type‐B characterized by c‐axes aligned parallel to lineation and b‐axes concentrated perpendicular to foliation, is essential for explaining the trench‐parallel seismic anisotropy in the forearc regions of subduction zones. However, its origin remains a subject of ambiguity and controversy. In this study, we present experimental findings on the formation of a type‐B olivine CPO through the dehydration of foliated serpentinite under a compressive stress at a pressure of 300 MPa and temperature of 700–750°C. Our results reveal a progressive evolution of olivine CPO, transitioning from a type‐C fabric to a type‐B fabric, with increasing grain size and dehydration level. The type‐B CPO observed in coarse‐grained olivine within fully dehydrated samples primarily arises from mechanisms involving anisotropic growth, grain rotation, and oriented coalescence of newly formed, small olivine grains following the decomposition of antigorite under a compressive stress. This study provides the first experimental evidence for a novel, low‐temperature dynamic dehydration mechanism, in contrast to the mechanism of high‐temperature plastic flow, for explaining the development of type‐B olivine CPO in forearc regions. Hence, it contributes significantly to our understanding of the formation of olivine CPO with implications for seismic anisotropy in subduction zone forearcs.
Sensitivity of GNSS‐Derived Estimates of Terrestrial Water Storage to Assumed Earth Structure

Published: March 2024

AbstractGeodetic methods can monitor changes in terrestrial water storage (TWS) across large regions in near real‐time. Here, we investigate the effect of assumed Earth structure on TWS estimates derived from Global Navigation Satellite System (GNSS) displacement time series. Through a series of synthetic tests, we systematically explore how the spatial wavelength of water load affects the error of TWS estimates. Large loads (e.g., >1,000 km) are well recovered regardless of the assumed Earth model. For small loads (e.g., <10 km), however, errors can exceed 75% when an incorrect model for the Earth is chosen. As a case study, we consider the sensitivity of seasonal TWS estimates within mountainous watersheds of the western U.S., finding estimates that differ by over 13% for a collection of common global and regional structural models. Errors in the recovered water load generally scale with the total weight of the load; thus, long‐term changes in storage can produce significant uplift (subsidence), enhancing errors. We demonstrate that regions experiencing systematic and large‐scale variations in water storage, such as the Greenland ice sheet, exhibit significant differences in predicted displacement (over 20 mm) depending on the choice of Earth model. Since the discrepancies exceed GNSS observational precision, an appropriate Earth model must be adopted when inverting GNSS observations for mass changes in these regions. Furthermore, regions with large‐scale mass changes that can be quantified using independent data (e.g., altimetry, gravity) present opportunities to use geodetic observations to refine structural properties of seismologically derived models for the Earth's interior structure.

AbstractBreast cancer is the most prevalent type of cancer in women worldwide. Within breast tumors, the basal-like subtype has the worst prognosis, prompting the need for new tools to understand, detect, and treat these tumors. Certain germline-restricted genes show aberrant expression in tumors and are known as Cancer/Testis genes; their misexpression has diagnostic and therapeutic applications. Here we designed a new bioinformatic approach to examine Cancer/Testis gene misexpression in breast tumors. We identify several new markers in Luminal and HER-2 positive tumors, some of which predict response to chemotherapy. We then use machine learning to identify the two Cancer/Testis genes most associated with basal-like breast tumors: HORMAD1 and CT83. We show that these genes are expressed by tumor cells and not by the microenvironment, and that they are not expressed by normal breast progenitors; in other words, their activation occurs de novo. We find these genes are epigenetically repressed by DNA methylation, and that their activation upon DNA demethylation is irreversible, providing a memory of past epigenetic disturbances. Simultaneous expression of both genes in breast cells in vitro has a synergistic effect that increases stemness and activates a transcriptional profile also observed in double-positive tumors. Therefore, we reveal a functional cooperation between Cancer/Testis genes in basal breast tumors; these findings have consequences for the understanding, diagnosis, and therapy of the breast tumors with the worst outcomes.

AbstractClear cell renal cell carcinoma (ccRCC) presents a unique profile characterized by high levels of angiogenesis and robust vascularization. Understanding the underlying mechanisms driving this heterogeneity is essential for developing effective therapeutic strategies. This study revealed that ubiquitin B (UBB) is downregulated in ccRCC, which adversely affects the survival of ccRCC patients. UBB exerts regulatory control over vascular endothelial growth factor A (VEGFA) by directly interacting with specificity protein 1 (SP1), consequently exerting significant influence on angiogenic processes. Subsequently, we validated that DNA methyltransferase 3 alpha (DNMT3A) is located in the promoter of UBB to epigenetically inhibit UBB transcription. Additionally, we found that an unharmonious UBB/VEGFA ratio mediates pazopanib resistance in ccRCC. These findings underscore the critical involvement of UBB in antiangiogenic therapy and unveil a novel therapeutic strategy for ccRCC.
