Abstract

Managing social‐ecological systems (SES) requires balancing the need to tailor actions to local heterogeneity and the need to work over large areas to accommodate the extent of SES. This balance is particularly challenging for policy since the level of government where the policy is being developed determines the extent and resolution of action.

We make the case for a new research agenda focused on ecological federalism that seeks to address this challenge by capitalizing on the flexibility afforded by a federalist system of governance. Ecological federalism synthesizes the environmental federalism literature from law and economics with relevant ecological and biological literature to address a fundamental question: What aspects of SES should be managed by federal governments and which should be allocated to decentralized state governments?

This new research agenda considers the bio‐geo‐physical processes that characterize state‐federal management tradeoffs for biodiversity conservation, resource management, infectious disease prevention, and invasive species control.

Published: February 2023

AbstractObjectiveThis study evaluated the prevalence and severity of depression and anxiety symptomatology, barriers to mental health access, and correlates of functional impairment among cancer inpatients.MethodsThis cross‐sectional study recruited adult cancer patients (N = 300) in June and July 2022 at the largest oncological hospital in Vietnam. Multivariable linear regression analyses examined the association between demographics, clinical characteristics, and patients' functional impairment.ResultsApproximately 46.3% and 27.0% showed some depression and anxiety symptomatology, while 8.0% and 3.0% experienced major depressive and anxiety symptoms, respectively. Patients reported the most impairment in mobility and capacity for life activities. More functional impairment was identified in patients with gastrointestinal cancers, those receiving radiation therapy alone, and those scoring higher on depression and anxiety than in those with cancers originating in the head, neck, or lung or those receiving chemotherapy alone. Reports of better overall health status were negatively associated with functional impairment. Patients reported extensive perceived barriers to seeking psychiatric care, including not knowing where to get mental health support (86.7%), wanting to manage mental health independently (73.7%), and thinking mental health will resolve on its own (73.7%), and denying mental health concerns (61.0%).ConclusionHigh frequency and severity of depression and anxiety symptomatology underscore the importance of integrating mental health services into existing oncological treatment protocols. Increasing mental health literacy and provision of psychoeducation is critical to addressing barriers to mental health service access. Integration of functional impairment evaluations into hospital admission and discharge planning is also needed.

AbstractObjectiveAnxiety and depression are common in cancer patients and seem to affect quality of life, treatment compliance and even survival. Defining factors related to anxiety and depression and exploring the role of demoralization and satisfaction with care, could contribute to the improvement of patients' quality of life and quality of health services as well.MethodsA convenience sample of 150 cancer inpatients and outpatients from two oncology centers, with various types of solid tumors, participated in a prospective cross‐sectional observational study. The psychometric tools used were the Greek versions of the Hospital Anxiety and Depression Scale, FAMCARE‐Patient Scale and Oncology Palliative Care (FAMCARESCALE) and Demoralization Scale (DEMORALIZATION SCALE II, DS‐II).ResultsPatients mean age was 62 years (20–85 years) and 89 patients (59.3%) were women. Among patients, 33% had breast, 24% gastrointestinal and 15% lung cancer. Eighty‐two patients (54.7%) had metastatic disease. Women showed higher rates of anxiety (p = 0.054). Anxiety was inversely related to age (p = 0.043) and positively correlated with time since diagnosis (p = 0.076). Unmarried patients presented with higher rates of depression (p = 0.026). Multiple linear regression showed a statistically significant impact of Demoralization factor ‘Meaning and Purpose’ on anxiety (p < 0.001, R2 = 36.3%) and depression (p < 0.001, R2 = 49%). Moreover, higher educational level (p = 0.038, R2 = 3.1%) is related to higher levels of anxiety and higher scores of FAMCARESCALE factor‐Information/interaction with the health care professionals, is related to lower levels of depression (p = 0.008, R2 = 2.7%).ConclusionsThe results highlight the significant impact of demoralization on anxiety and depression in cancer patients. Early recognition of demoralization and early referral to mental health professionals will hopefully alleviate the mental burden of cancer patients.
Orbiting Self‐Organization of Filament‐Tethered Surface‐Active Droplets

Published: February 2023

AbstractDissipative chemical systems hold the potential to enable life‐like behavior in synthetic matter, such as self‐organization, motility, and dynamic switching between different states. Here, out‐of‐equilibrium self‐organization is demonstrated by interconnected source and drain droplets at an air‐water interface, which display dynamic behavior due to a hydrolysis reaction that generates a concentration gradient around the drain droplets. This concentration gradient interferes with the adhesion of self‐assembled amphiphile filaments that grow from a source droplet. The chemical gradient sustains a unique orbiting of the drain droplet, which is proposed to be driven by the selective adhesion of the filaments to the front of the moving droplet, while filaments approaching from behind are destabilized upon contact with the hydrolysis product in the trail of the droplet. Potential applications are foreseen in the transfer of chemical signals amongst communicating droplets in rearranging networks, and the implementation of chemical reactions to drive complex positioning routines in life‐like systems.

Published: February 2023

AbstractCreation of architectures with exquisite hierarchies actuates the germination of revolutionized functions and applications across a wide range of fields. Hierarchical self‐assembly of colloidal particles holds the promise for materialized realization of structural programing and customizing. This review outlines the general approaches to organize atom‐like micro‐ and nanoparticles into prescribed colloidal analogs of molecules by exploiting diverse interparticle driving motifs involving confining templates, interactive surface ligands, and flexible shape/surface anisotropy. Furthermore, the self‐regulated/adaptive co‐assembly of simple unvarnished building blocks is discussed to inspire new designs of colloidal assembly strategies.
The ethics of climate activism
Authors: Garcia‐Gibson Francisco 
Published: February 2023

AbstractClimate activism, and ethical reflection on it, is expanding in line with increased awareness of global warming's destructive effects. The ethics of climate activism has focused on two main questions. First, is there a duty to engage in climate activism? Answers to this question differ regarding how the duty is grounded, how demanding it is, and whether people in certain social roles have special duties to engage in climate activism. The second question is whether certain forms of climate activism are morally permissible, given certain frequently voiced concerns. Prominently, concerns about climate activism being ineffective, uninclusive, undemocratic, and violent. The review ends by pointing to other issues that the ethics of climate activism is likely to address in the near future.This article is categorized under:Climate, Nature, and Ethics > Ethics and Climate Change
The Nature and the Policy Added Value of EU Integrated Urban Initiatives: Research Issues and Strategies
Authors: Rodríguez-García María Jesús , Navarro Yáñez Clemente J. , Guerrero-Mayo María José 
Published: February 2023

AbstractAfter reviewing the main research strategies applied to analyse urban initiatives promoted by the EU, this chapter proposes the ‘urban policy portfolio analysis’ (CUPPA) approach to perform comparative analyses at the level of local strategies. Previous exercises about EU urban initiatives have analysed their legal framework, applied the classical programme perspective (spending and other aspects) or studied specific case studies. These approaches study the urban dimension of the European Cohesion Policy or national applications as a whole or provide in-depth information about detailed local plans. However, these approaches do not provide systematic information to perform comparative analyses at the local strategies level. The CUPPA approach provided comparative methods to perform bottom-up analyses (from the local strategy level to policy frames) of design and implementation processes theoretically founded in previous research on urban policies. Therefore, this approach is aligned with the multi-level and complex character of integrated urban strategies promoted by the EU. And, therefore, allow for multi-scalar comparative analyses of strategies (at the local level) and the actual character of policy frames (regional, national, and EU levels) from a cross-time and cross-sectional perspective.

AbstractAffirming affective framings of lesbian, gay, bisexual, transgender and queer (LGBTQ+) experiences are needed in education research. Drawing on the2021 LGBTQ+ Yousurveys, this chapter explores experiences of euphoria in Australian education institutions among 2407 LGBTQ+ staff, parents, and students participants and how these changed over time. Staff members and out LGBTQ+ participants were more likely to have euphorias; heterosexuals, parents, and those in religious or rural schools were less likely.Community Connection,Institutional Inclusion,AcceptanceandCategory Validation euphoriaswere most common. Change-trends included: (1) expansion ofCommunity Connection euphoriathrough socialisation, (2) gradual building ofAcceptance euphoria,(3) site-specific changes inInstitutional Inclusion euphoria,(4) sudden shifts inCategory Validation euphoria,and (5) removal or addition of euphoria blockers especially the spectre of parental backlash.
LGBTQ+ Parents’ Euphorias! Consistencies in LGBTQ+ parents’ Happiness & Comfort
Authors: Jones Tiffany 
Published: February 2023

AbstractLesbian, gay, bisexual, transgender, and queer (LGBTQ+) parents’ rights were openly debated around marriage legislation movements. Religious schools can deny their families services. This chapter investigates 208 LGBTQ+ parents’ euphorias in their children’s schools. Under a third of them were euphoric and mostly always or often; gay or lesbian parents were more likely to experience euphorias and parents with disabilities were less likely. Institutional Inclusion, Category Validation, Pride Generativity, and Community Connection euphorias dominated. Most parents reported no changes to their euphorias. Change-trends included: (1) increased expectation for Institutional Inclusion euphoria; (2) steady growth in (Self-) Acceptance euphoria; (3) relationships and relationship views as a moderating factor; (4) learning and teaching euphorias; and (5) time as an enabling factor. Parent euphorias had stable and revolutionary qualities.

Published: February 2023

AbstractKuramoto–Velarde equation describes the spatiotemporal evolution of the morphology of steps on crystal surfaces, or the evolution of the spinoidal decomposition of phase separating systems in an external field. We prove the well-posedness of the classical solutions for the Cauchy problem, associated with this equation for each choice of the terminal timeT.
On the Exponential Decay of Strongly Interacting Cold Atoms from a Double-Well Potential
Authors: Kościk Przemysław 
Published: February 2023

AbstractIn this article, we study an exponential decay for the gas of bosons with strong repulsive delta interactions from a double-well potential. We consider an exactly solvable model comprising an infinite wall and two Dirac delta barriers. We explore its features both within the exact method and with the resonance expansion approach. The study reveals the effect of the splitting barrier on the decay rate in dependence on the number of particles. Among other things, we find that the effect of the splitting barrier on the decay rate is most pronounced in systems with odd particle numbers. During exponential decay, the spatial correlations in an internal region are well captured by the “radiating state”.

Published: February 2023

AbstractRecent devastating earthquakes worldwide pointed out the importance of seismic detailing and their influence on the observed damage and subsequent repairability of reinforced concrete buildings. Several studies and post-earthquake observations remarked the role of beam–column joints (BCJs) on the global building response and the effectiveness of transverse reinforcement in increasing the joint shear strength and the ultimate deformation. Although number of experimental and theoretical studies focused on the seismic response of BCJs, their mechanical behaviour is still a discussed topic. This resulted in number of design approaches available in worldwide code or standards that lead to different quantity of joint stirrups. This study focuses on the response of BCJs of a 10-story prototype building designed according to Japanese standards and tested in 2015 on the E-Defense shaking table. First the damage assessment at global (building) and local (joint) level is performed at increasing intensities and considering the building in the base slip and base fixed configurations. A refined numerical model is then developed and validated against global and local experimental results. Then, the joint stirrups are re-designed according to different international standards (ACI, EC8, NZS) and different numerical models are developed. The numerical results are then compared in terms of interstorey drift demand and joint shear strain. Finally, a comparison in terms of expected damage varying the design approach of joint stirrups is proposed.
New cryptanalysis of LowMC with algebraic techniques
Authors: Qiao Wenxiao , Yan Hailun , Sun Siwei , Hu Lei , Jing Jiwu 
Published: February 2023

AbstractLowMC is a family of block ciphers proposed by Albrecht et al. at EUROCRYPT 2015, which is tailored specifically for FHE and MPC applications. At ToSC 2018, a difference enumeration attack was given for the cryptanalysis of low-data instances of full LowMCv2 with few applied S-boxes per round. Recently at CRYPTO 2021, an efficient algebraic technique was proposed to attack 4-round LowMC adopting a full S-box layer. Following these works, we present a new difference enumeration attack framework, which is based on our new observations on the LowMC S-box, to analyze LowMC instances with a full S-box layer. As a result, with only 3 chosen plaintexts, we can attack 4-round LowMC instances which adopt a full S-box layer with block size of 129, 192, and 255 bits, respectively. We show that all these attacks have either a lower time complexity or a higher success probability than those reported in the CRYPTO paper.
Quasi optimal anticodes: structure and invariants
Authors: Gorla Elisa , Landolina Cristina 
Published: February 2023

AbstractIt is well-known that the dimension of optimal anticodes in the rank-metric is divisible by the maximum m between the number of rows and columns of the matrices. Moreover, for a fixed k divisible by m, optimal rank-metric anticodes are the codes with least maximum rank, among those of dimension k. In this paper, we study the family of rank-metric codes whose dimension is not divisible by m and whose maximum rank is the least possible for codes of that dimension, according to the Anticode bound. As these are not optimal anticodes, we call them quasi optimal anticodes (qOACs). In addition, we call dually qOAC a qOAC whose dual is also a qOAC. We describe explicitly the structure of dually qOACs and compute their weight distributions, generalized weights, and associated q-polymatroids.
The Laws of Nature and the Problems of Modern Cosmology
Authors: Gaspar Yves , Tambor Paweł 
Published: February 2023

AbstractThe notion that nature is subject to laws is exciting from many different viewpoints. This paper is based on the context of modern cosmology. It will list the significant interdisciplinary implications generated by various aspects of the contemporary scientific discussion about the status of laws of nature, especially their dynamic nature. Recent work highlights how multiple aspects of the observed universe still lack explanation and that several problems of standard cosmology still form the object of debate. Considering these issues, several proposals have been made that entail a revision of the concept of the law of nature, according to which the nature of time and of the relation between causality and natural laws ought to be reconsidered using approaches or viewpoints which point to philosophical issues. We argue that Tim Maudlin’s concept of Fundamental Law of Temporal Evolution (FLOTE) and Nancy Cartwright’s notion of the nomological machine provide new insights and valuable tools that can be used in the analysis of the status of laws in the context of cosmology and of complex systems theory. The limits of the traditional approach to laws of nature and their mathematical formulation are highlighted in this context, as well as the fact that many of the ultimate properties of nature may turn out to be formally unpredictable or uncomputable.

Published: February 2023

AbstractM-type Barium hexaferrite is a famous hard magnetic material with a hexagonal crystal structure. La substituted Barium hexaferrite, Ba(1-x)La(x)Fe12O19, (where, x = 0.25 and 0.30) were synthesized using ball milling followed by sintering at 1300 °C for 5 hours. X-ray diffraction patterns reveal the formation of a single-phase magnetoplumbite structure of barium hexaferrite, which belongs to the P63/mmc space group. Mossbauer spectroscopic studies were carried out to study the magnetic phase, the effect of La doping on the valency of the Fe atom, and charge distribution in the prepared samples. Mossbauer spectra is fitted using 5 sextets, shows there is 5 sublattices present in the system. From the fitting of Mossbauer spectrum, it is observed that, there is no formation of Fe2+ ion even if the doping levels are as high as 30%, as it is expected that Fe3+ ion changes its valance to maintain the charge neutrality. However, there is an increase in s-electron density for number of sites with doping. Quadrupole splitting values shows spherical charge distribution for all the sublattices except 2b, due to asymmetric nature of bipyramidal site. Slightly varied magnetic hyperfine splitting values are observed for 12 k and 4f1 sites shows the effect of La substitution.
Synthesis and thermal characterization of porous polymeric microspheres functionalized with thiol groups
Authors: Maciejewska Magdalena , Grochowicz Marta 
Published: February 2023

AbstractThe paper presents a method of the preparation and functionalization of polymer microspheres consisting of glycidyl methacrylate (GMA) and crosslinking agents: 1,4-dimethacryloyloxybenzene (1,4DMB) and trimethylolpropane trimethacrylate (TRIM). Poly(GMA-co-1,4DMB) and poly(GMA-co-TRIM) microspheres were obtained by seed swelling polymerization. To introduce thiol groups into the microspheres structure, the reaction with thiocarboxylic acids was performed. The chemical structure of parent and modified microspheres was confirmed by FTIR and Raman spectroscopy. Elemental composition of microspheres after functionalization was determined by elemental analysis. The analysis showed the percentage of sulfur in the range of 2.78–4.51%, which corresponds to a concentration of thiol group in the range of 0.87–1.41 mmol g−1. Additionally, the porous structure of the copolymers was investigated using the low-temperature nitrogen adsorption–desorption method. The starting microspheres are characterized by a specific surface in the range of 150–160 m2 g−1, whereas functionalized copolymers indicate slightly lower surface area, of about 130 m2 g−1. The thermal stability of the materials was determined by the method of differential scanning calorimetry and thermogravimetric analysis. The course of the thermal degradation under oxidative conditions of modified microspheres is different from the starting copolymers. The functionalized microspheres showed much higher thermal stability (approximately 270 °C) compared to the starting microspheres (230–250 °C).
