Promoting Law Beyond the State

Abstracts In countries receiving foreign aid, non-state justice systems rooted in custom or religion generally handle most legal disputes. This dramatically influences the prospects of international efforts to promote the rule of law, yet scholars have paid little attention to foreign policy toward non-state justice. This paper explores how the nine largest rule-of-law-assistance providers engaged non-state justice between 2008 and 2018, illuminating the theory behind, and the reality of, donor-state policy. It proposes a new classificatory typology of donor approaches to non-state justice detailing five strategies (denial, acknowledgment, acceptance, transformation, and rejection) and four goals (judicial reform, symbolic recognition, state-building, and counterinsurgency). It then explores how the nine largest rule-of-law-assistance donor states addressed non-state justice through a structured comparison of policy documents as well as case studies of the five donors with the most comprehensive approaches. Donors strongly favored risk-averse approaches, even when this made success unlikely. Certain policy goals—such as state-building or counterinsurgency—sometimes prompted riskier choices, but only with a compelling justification and a reasonable prospect of success. Overall, major rule-of-law donors displayed risk-averse, superficial policy, minimal stakeholder engagement, a failure to grapple with the nuances of legal pluralism, and a lack of evidence to support existing policies.

Integrated Planning and Operation Dispatching of Source–Grid–Load–Storage in a New Power System: A Coupled Socio–Cyber–Physical Perspective

The coupling between modern electric power physical and cyber systems is deepening. An increasing number of users are gradually participating in power operation and control, engaging in bidirectional interactions with the grid. The evolving new power system is transforming into a highly intelligent socio–cyber–physical system, featuring increasingly intricate and expansive architectures. Demands for stable system operation are becoming more specific and rigorous. The new power system confronts significant challenges in areas like planning, dispatching, and operational maintenance. Hence, this paper aims to comprehensively explore potential synergies among various power system components from multiple viewpoints. It analyzes numerous core elements and key technologies to fully unlock the efficiency of this coupling. Our objective is to establish a solid theoretical foundation and practical strategies for the precise implementation of integrated planning and operation dispatching of source–grid–load–storage systems. Based on this, the paper first delves into the theoretical concepts of source, grid, load, and storage, comprehensively exploring new developments and emerging changes in each domain within the new power system context. Secondly, it summarizes pivotal technologies such as data acquisition, collaborative planning, and security measures, while presenting reasonable prospects for their future advancement. Finally, the paper extensively discusses the immense value and potential applications of the integrated planning and operation dispatching concept in source–grid–load–storage systems. This includes its assistance in regards to large-scale engineering projects such as extreme disaster management, facilitating green energy development in desertification regions, and promoting the construction of zero-carbon parks.

Entrepreneurial Tendencies and Intentions of Students in a Rural-based Technical and Vocational Education and Training College

In an environment with unprecedented unemployment levels, entrepreneurship is promoted as an approach that has a potentially positive effect on the economy through innovation and employment creation. The objective of the current study was to determine entrepreneurial interest and intention among college students. This study examined the entrepreneurial tendencies of students registered for an entrepreneurship module in a college. The study was quantitative and used Caird’s General Enterprising Tendencies Questionnaire to collect information from students registered at the local college. The theory of planned behavior was utilized to explore whether, if the students have an interest in business, they are also inclined to act on that desire to participate in business undertakings. The results suggested that the students in the study possessed the tendency to be entrepreneurial and were keen to start businesses at some point in their lives. Yet, they mostly do not intend to start business ventures for several reasons, including fear of failure. The study contributes to the knowledge that underprivileged still contributes to a lack of entrepreneurial inclination, and support is paramount in nurturing that entrepreneurial interest. The study recommends that the college’s entrepreneurship education emphasizes information about reasonable small business prospects in the area; provide relevant information such as funding or registration, for the encouragement and advancement of especially youth-owned businesses; and host dialogues that should be delivered by young successful small business owners or managers.

Challenges and Prospects of Contemporary Nigerian Textile Design

Nigerian textile in all its ramifications is one of the oldest art practices in Nigeria. While it is worthwhile to note that textile design repertoire has been a major part of the nation’s identity, textile designers who form a considerable part of the workforce are confronted with challenges. On one hand, the current trend in globalisation has exposed textile designers to new materials and techniques as well as the potential influences of other world cultures. This paper contends that in the quest to become globalised, the traditional African cultural heritage is being sacrificed on the altar of modernization. On the other hand, the introduction of new materials and techniques counts among the instruments or tools for positive impact. It is on this premise that one can say that contemporary Nigerian textile designers alongside their designs are reminiscent or reflect a society in the cusps of change in terms of challenges and prospects. Hence, this article offers some useful knowledge on this development as it establishes the extent to which Nigerian textile designers had suffered from several inadequacies that posed as challenges. It also highlights some reasonable prospects for growth or advancement in the industry in Nigeria.

Nutrient and mycoremediation of a global menace 'arsenic': exploring the prospects of phosphorus and Serendipita indica-based mitigation strategies in rice and other crops.

Serendipita indica induced metabolic reprogramming in colonized plants complements phosphorus-management in improving their tolerance to arsenic stress on multifaceted biological fronts. Restoration of the anthropic damage done to our environment is inextricably linked to devising strategies that are not only economically sound but are self-renewing and ecologically conscious. The dilemma of heavy metal (HM) dietary ingestion, especially arsenic (As), faced by humans and animals alike, necessitates the exploitation of such technologies and the cultivation of healthy and abundant crops. The remarkable symbiotic alliance between plants and 'mycorrhizas' has evolved across eons, benefiting growth/yield aspects as well as imparting abiotic/biotic stress tolerance. The intricate interdependence of Serendipita indica (S. indica) and rice plant reportedly reduce As accumulation, accentuating the interest of microbiologists, agriculturists, and ecotoxicological scientists apropos of the remediation mechanisms of As in the soil-AMF-rice system. Nutrient management, particularly of phosphorus (P), is also praised for mitigating As phytotoxicity by deterring the uptake of As molecules due to the rhizospheric cationic competition. Taking into consideration the reasonable prospects of success in minimizing As acquisition by rice plants, this review focuses on the physiological, metabolic, and transcriptional alterations underlying S. indica symbiosis, recuperation of As stress together with nutritional management of P by gathering case studies and presenting successful paradigms. Weaving together a volume of literature, we assess the chemical forms of As and related transport pathways, discuss As-P-rice interaction and the significance of fungi in As toxicity mitigation, predominantly the role of mycorrhiza, as well as survey of the multifaceted impacts of S. indica on plants. A potential strategy for simultaneous S. indica + P administration in paddy fields is proposed, followed by future research orientation to expand theoretic comprehension and encourage field-based implementation.

Underwater Robots and Key Technologies for Operation Control

Over time, the utilization of the Underwater Vehicle-Manipulator System (UVMS) has steadily increased in exploring and harnessing marine resources. However, the underwater environment poses big challenges for controlling, navigating, and communicating with UVMS. These challenges have not only spurred the continuous advancement of related technologies, but also made the development of the UVMS even more captivating. This article firstly provides a review of development status of the UVMS and discusses the current limitations and future directions, and then reviews in detail the dynamic and hydrodynamic modeling methods, and analyzes the principles, advantages, and disadvantages of various approaches. Then, we try to review 2 key technologies of operation control methods, including underwater positioning and navigation technologies and vehicle-manipulator coordinated control approaches. Finally, a reasonable prospect for the future development of UVMS is given.

Rare earth oxide based electrocatalysts: synthesis, properties and applications.

As an important strategic resource, rare earths (REs) constitute 17 elements in the periodic table, namely 15 lanthanides (Ln) (La-Lu, atomic numbers from 57 to 71), scandium (Sc, atomic number 21) and yttrium (Y, atomic number 39). In the field of catalysis, the localization and incomplete filling of 4f electrons endow REs with unique physical and chemical properties, including rich electronic energy level structures, variable coordination numbers, etc., making them have great potential in electrocatalysis. Among various RE catalytic materials, rare earth oxide (REO)-based electrocatalysts exhibit excellent performances in electrocatalytic reactions due to their simple preparation process and strong structural variability. At the same time, the electronic orbital structure of REs exhibits excellent electron transfer ability, which can reduce the band gap and energy barrier values of rate-determining steps, further accelerating the electron transfer in the electrocatalytic reaction process; however, there is a lack of systematic review of recent advances in REO-based electrocatalysis. This review systematically summarizes the synthesis, properties and applications of REO-based nanocatalysts and discusses their applications in electrocatalysis in detail. It includes the hydrogen evolution reaction (HER), oxygen evolution reaction (OER), hydrogen oxidation reaction (HOR), oxygen reduction reaction (ORR), carbon dioxide reduction reaction (CO2RR), methanol oxidation reaction (MOR), nitrogen reduction reaction (NRR) and other electrocatalytic reactions and further discusses the catalytic mechanism of REs in the above reactions. This review provides a timely and comprehensive summary of the current progress in the application of RE-based nanomaterials in electrocatalytic reactions and provides reasonable prospects for future electrocatalytic applications of REO-based materials.

Assessing the Decade After: A Critical Analysis of Responsibility to Protect (R2P) in the Libya Intervention

Currently, 12 years post-NATO intervention, Libya falls into the category of a fragile state, with worsening indices in the economic, security, and social aspects since 2011. While not a new topic, the situation in Libya in 2011 can always serve as a lesson and exemplification of the discourse on humanitarian intervention, specifically the principal aspects of Responsibility to Protect (R2P). The current situation in Libya raises questions about whether there were flaws in the military intervention carried out by the NATO alliance in 2011. This paper aims to analyze the just ad bellum features related to the principal aspects within R2P were implemented in the NATO intervention in Libya. Thus, this study argues that the failure of the military intervention in Libya is due to the non-fulfillment of the basic aspects of Responsibility to Protect (R2P), especially in relation to just ad bellum, such as right authority, last resort, just cause, right intention, proportional means, and reasonable prospects in carrying out humanitarian intervention.

Bioethanol Production Based on Saccharomyces cerevisiae: Opportunities and Challenges

The large consumption of non-renewable fossil fuels has brought about energy depletion and environmental pollution, spawning the production of renewable biofuels, an important alternative to alleviate the energy crisis effectively. As one of the ideal types of biofuel, bioethanol synthesis in Saccharomyces cerevisiae has attracted much attention. S. cerevisiae has been developed as essential chassis cells with high efficiency for bioethanol synthesis on account of many advantages. This study systematically summarized the preponderance of S. cerevisiae in biosynthesis. It objectively stated the research strategies of bioethanol synthesis based on S. cerevisiae and the existing bottleneck problems. This study further proposed reasonable prospects for bioethanol synthesis by S. cerevisiae, attempting to provide alternative research strategies.

Cost-Effective Engineered Cementitious Composites with Hybrid PVA and Basalt/PP Fiber: A Study on Compressive, Tensile and Impact Performance.

Currently, oil-coated PVA fibers are the most commonly used material in ECC research. However, the high price limits the application of PVA-ECC in practical engineering. In order to reduce the cost, one of the methods is to partially replace the PVA fibers in ECC. In order to demonstrate the feasibility of PVA/BF-ECC and PVA/PP-ECC, polyvinyl alcohol fibers (PVA), basalt fibers (BFs) and polypropylene fibers (PP) were added at 0.5%, 1.0% and 1.5% by volume of PVA in addition to 1% by volume of PVA. Subsequently, tensile, compression and drop-weight impact tests were conducted on single or hybrid fiber concrete. The results showed that the post-peak compression toughness, tensile strength, and initial cracking impact strength of PVA/BF-ECC and PVA/PP-ECC increased significantly with the increase in the volume ratio of BF and PP fibers, while the performance of PVA-ECC materials with the same fiber volume ratio decreased slightly. Therefore, the cost can be reduced by designing hybrid PVA/BF-ECC materials that meet the performance requirements. The experimental evidence presented in this study demonstrates the feasibility and reasonable prospect of the new hybrid PVA/BF-ECC.

Right to an Effective Remedy in the European Convention on Human Rights


 
 The article is dedicated to the right to an effective remedy in the European Convention on Human Rights (the Convention) which guarantees the availability at national level of a remedy to enforce the substance of the Convention rights and freedoms in whatever form they may happen to be secured in the domestic legal order. Article 13 of the Convention obliges the States to protect human rights within their legal system. The States’ primary obligation deriving from Article 13 is to guarantee the availability of an effective remedy at the domestic level which must be “effective” in practice as well as in law. Moreover, the States have an obligation to demonstrate convincingly the existence of an effective remedy in the practice. At the same time, that provision obliges individuals to exhaust all effective remedies before they lodge their applications with the European Court of Human Rights (the Court). However, they are only obliged to exhaust the remedies that are effective and capable of redressing the alleged violation, accessible and offering reasonable prospects of success. Additionally, this provision creates a basis for the Court to examine the existence and effectiveness of the domestic remedies. 
 The article analyses the Court’s case-law concerning the interplay of the parties’ obligations corresponding to the right an effective remedy from the perspective the subsidiarity of the Convention system: the primary responsibility for implementing and enforcing the rights and freedoms guaranteed by the Convention is placed on the national authorities.

Label-free detection of virus based on surface-enhanced Raman scattering

Due to the background interference from biological samples, detecting viruses using surface-enhanced Raman scattering (SERS) in clinical samples is challenging. This study is based on SERS by reducing sodium borohydride and aggregating silver nanoparticles to develop suitable virus detection “hot spot.” The monkeypox virus and human papillomavirus fingerprints were quickly obtained, tested, and identified in serum and artificial vaginal discharge, respectively, by combining the principal component analysis method. Therefore, these viruses were successfully identified in the biological background. In addition, the lowest detection limit was 100 copies/mL showing good reproducibility and signal-to-noise ratio. The concentration-dependent curve of the monkeypox virus had a good linear relationship. This method helps solve the SERS signal interference problem in complex biological samples, with low detection limits and high selectivity in virus characterization and quantitative analysis. Therefore, this method has a reasonable prospect of clinical application.

Measuring Detection Efficiency of High-Residency Acoustic Signals for Estimating Probability of Fish–Turbine Encounter in a Fast-Flowing Tidal Passage

Semidiurnal tidal currents can exceed 5 ms−1 in Minas Passage, Bay of Fundy, where a tidal energy demonstration area has been designated to generate electricity using marine hydrokinetic turbines. The risk of harmful fish–turbine interaction cannot be dismissed for either migratory or local fish populations. Individuals belonging to several fish populations were acoustically tagged and monitored by using acoustic receivers moored within the Minas Passage. Detection efficiency ρ is required as the first step to estimate the probability of fish–turbine encounter. Moored Innovasea HR2 receivers and high-residency (HR) tags were used to obtain detection efficiency ρ as a function of range and current speed, for near-seafloor signal paths within the tidal energy development area. Strong tidal currents moved moorings, so HR tag signals and their reflections from the sea surface were used to measure ranges from tags to receivers. HR2 self-signals that reflected off the sea surface showed which moorings were displaced to lower and higher levels on the seafloor. Some of the range testing paths had anomalously low ρ, which might be attributed to variable bathymetry blocking the line-of-sight signal path. Clear and blocked signal paths accord with mooring levels. The application of ρ is demonstrated for the calculation of abundance, effective detection range, and detection-positive intervals. High-residency signals were better detected than pulse position modulation (PPM) signals. Providing that the presently obtained ρ applies to tagged fish that swim higher in the water column, there is a reasonable prospect that probability of fish–turbine encounter can be estimated by monitoring fish that carry HR tags.

Here’s something we prepared earlier: Development, use and reuse of a configurable, inter-disciplinary approach for tackling overcrowding in NHS hospitals

Overcrowding affects hospital emergency departments (ED) worldwide. Most OR studies addressing overcrowding develop bespoke models to explore potential improvements but ignore the organisational context in which they would be implemented, and few influence practice. There is interest in whether reusable models, for ED crowding and in healthcare generally, could have more impact. We developed a configurable approach for tackling ED overcrowding. A reusable queuing model for exploring drivers of ED performance was augmented by a qualitative approach for exploring the implementation context and a generic framework for assessing the likely compatibility of interventions with a given organisation. At the hospital where the approach was developed it directly informed strategy. We describe reuse of the approach at three hospitals. One project was completed and well-received by hospital management, two were terminated partway when data problems surfaced. The primary contribution of this work is its novelty in considering, alongside quantitative modelling, evidence-based interventions to overcrowding and qualitative assessment of a hospital’s aptitude and capability to adopt different interventions. A secondary contribution is to further the debate on model reuse, particularly by introducing more complex, modelling-centred approaches that acknowledge how models must relate to tangible interventions with reasonable prospects of being adopted locally.

Hydrocarbon indication in Rio Bonito Formation sandstone: Implication for CO2 storage in São Paulo, Brazil

São Paulo State has witnessed CO2 storage-based investigations considering the availability of suitable geologic structures and proximity to primary CO2 source sinks related to bioenergy and carbon capture and storage (BECCS) activities. The current study presents the hydrocarbon viability evaluations and CO2 storage prospects, focusing on the sandstone units of the Rio Bonito Formation. The objective is to apply petrophysical evaluations with geochemical inputs in predicting future hydrocarbon (gas) production to boost CO2 storage within the study location. The study used data from eleven wells with associated wire-line logs (gamma ray, resistivity, density, neutron, and sonic) to predict potential hydrocarbon accumulation and fluid mobility in the investigated area. Rock samples (shale and carbonate) obtained from depths >200 m within the study location have shown bitumen presence. Organic geochemistry data of the Rio Bonito Formation shale beds suggest they are potential hydrocarbon source rocks and could have contributed to the gas accumulations within the sandstone units. Some drilled well data, e.g., CB-1-SP and TI-1-SP, show hydrocarbon (gas) presence based on the typical resistivity and the combined neutron-density responses at depths up to 3400 m, indicating the possibility of other hydrocarbon members apart from the heavy oil (bitumen) observed from the near-surface rocks samples. From the three-dimensional (3-D) model, the free fluid indicator (FFI) is more significant towards the southwest and southeast of the area with deeper depths of occurrence, indicating portions with reasonable hydrocarbon recovery rates and good prospects for CO2 injection, circulation and permanent storage. However, future studies based on contemporary datasets are required to establish the hydrocarbon viability further, foster gas production events, and enhance CO2 storage possibilities within the region.

Assessing Opportunities and Difficulties in Hydroponic Farming

Background: Hydroponics or water-culture-based agricultural systems are devoted to a reasonable prospect for future farming agriculture production. Especially in that region where the fertility of agricultural land is continuously going to there is a decline in groundwater level for irrigation. Hydroponics-based agriculture system realizes an admiring action towards an eco-friendly system and innovative technique to overcome challenges concerning food safety. Hydroponics is an advanced agriculture technique in which the plants grow without soil and without any pesticide use. It is used to grow plants, vegetables and shrubs on vertical as well as horizontal basis in the series and parallel. It could be applied via glass pots, clay pots, PVC pipes and useless plastic buckets and bottles. Methods: In the present study vegetables, flowering plants and shrubs were grown successfully by the use of mainly three techniques of hydroponics namely Kratky, Wick and DFT methods. This study was continued for two and half years (4th July 2020 to 21st March 2021 and December 2019 to April 2020) with controlled pH and TDS of the nutrient solution and conducted at different Indian climatic, weather and seasonal conditions at Markanda National College,Shahabad Markanda and at the researcher’s home. Several vegetables and plants were grown from Kratky, Wick and DFT hydroponics methods under continuous monitoring of pH and TDS of nutrient solutions. Result: During the conduction of this study of the growth of mustard, ladyfinger, spinach, marigold, daisy basil (Tulsi), cucumber, cauliflower, broccoli, tomatoes, peas, peppermint, coriander leaves plants in different sessions; some challenges and opportunities were discussed. The main objective of this research study is to spread awareness about novel types of advanced future agricultural techniques or farming among the farmers and masses, who have an interest in agriculture but cannot fulfill their ambitions towards agriculture farming due to scarcity of agricultural land. The results obtained from the growth of vegetable and plant through hydroponics methods province us to follow an idea to use of such agricultural techniques. We have grown several below said crops/vegetables two or three times and face several problems. It is an opportunity to overcome the world’s food scarcity at a large scale, if adopted by a large population all over the world.

“Reasonable prospects” in mineral resource estimation and reporting

ABSTRACT A fundamental component of the Definition Standards for Mineral Resources is the requirement that the material have “reasonable prospects for eventual economic extraction” (RPEEE). The first adoption of the RPEEE requirement by a widespread group was in 1997 as part of the Denver Accord meeting and has since become an international standard. Mineral resource statements are prepared for mineral properties that are at various stages in the mining cycle, from the discovery stage through to the production stage. The confidence level of information available for the development of the input parameters for the technical and economic components of RPEEE varies greatly among stages. Consequently, the RPEEE assumptions may evolve with the stage of the mineral property as well. The economic aspects of RPEEE are commonly achieved by selecting appropriate input parameters for establishing a cut-off grade. The technical aspects can include consideration of such items as minimum widths, spatial continuity, and the application of appropriate constraining surfaces and volumes. In all cases, the responsibility of ensuring that the mineral resource statements are prepared in accordance with the requirements of the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards ultimately resides with the qualified person.

Treatment Outcomes of Patients With Ruptured Abdominal Aortic Aneurysms.

Ruptured abdominal aortic aneurysm (rAAA) is a serious complication of abdominal aortic aneurysm associated with high operative mortality and morbidity rates. The present study evaluated the perioperative and long-term outcomes of Korean patients with rAAA based on national health insurance claims data. The National Health Insurance Service (NHIS) database was searched retrospectively to identify patients with rAAA who underwent endovascular aneurysm repair (EVAR) and open surgical repair (OSR) from 2009 to 2018. Perioperative (≤ 30 days), early postoperative (≤ 3 month), and long-term (> 3 month) survival, reinterventions, and complications were assessed. The search identified 1,034 patients with rAAA, including 594 who underwent EVAR and 440 who underwent OSR. When the study period was divided into two, the total numbers of patients with rAAA, patients who underwent EVAR, and octogenarians were higher during the second half. The perioperative mortality rate was 29.8% in the EVAR and 35.0% in the OSR group (P = 0.028). Hartmann's procedure for bowel infarction was performed more frequently in the OSR than in the EVAR group (adjusted odds ratio, 6.28; 95% confidence interval [CI], 2.33-21.84; P = 0.001), but other complication rates did not differ significantly. All-cause mortality during the entire observation period did not differ significantly in the EVAR and OSR groups (adjusted hazard ratio, 1.17; 95% CI, 0.98-1.41; P = 0.087). Abdominal aortic aneurysm-related reintervention rate was significantly lower in the OSR group (adjusted hazard ratio, 0.31; 95% CI, 0.14-0.70; P = 0.005). Although EVAR showed somewhat superior perioperative outcomes for rAAA, the long-term outcomes of EVAR after excluding initial 3 months were significantly worse than OSR. When anatomically feasible for both treatments, the perioperative mortality risk and reasonable prospects of long-term survival should be considered in rAAA.
