Transition to organic farming negatively affects bat activity.

The effectiveness of organic farming on biodiversity has been widely documented especially for plants, arthropods and birds; however, the effects of the transition period required to become an organic farm on wildlife remain poorly understood.We assessed the effects of organic farming on insectivorous bats in citrus orchards in the Republic of Cyprus employing two matched designs (conventional vs. 3-year organic-transitional and conventional vs. organic-certified) and a third unmatched design (3-year organic-transitional vs. organic-certified). We specifically investigated whether the transition period prior to full organic certification influenced bat activity with a special focus on any moderation effects from surrounding semi-natural areas.The activity of three (Pipistrellus kuhlii, Hypsugo savii and Miniopterus schreibersii) of four bat species was significantly lower in farms undergoing the transitional period than in conventional farms, and P. kuhlii and H. savii were significantly less active in organic transitional farming systems that in organic-certified ones. Furthermore, the activity of the most dominant species (P. kuhlii) was significantly higher on organic than transitional and conventional citrus orchards, thus suggesting a time-lag effect. Landscape complexity measured as the amount of semi-natural areas did not moderate the effects of farming system for any study species. Synthesis and application. The transition to organic farming had persistent detrimental effects on bats and potentially on the pest suppression services they provide. Future agri-environmental policy should consider the transition period and implement measures to mitigate any negative effects on biodiversity, alongside promoting asynchronous transition of nearby farms. Our findings further highlight the crucial need to consider the time since transition to organic farming when assessing potential benefits of organic management on biodiversity.

Transitivity Analysis of AJ Hoge’s Short Story “Day of the Dead”

This study analyzes a short story created by AJ Hoge, a well-known English Materials creator of effortless English learning with his short story. It aims to reveal how meanings are constructed and what characterizes the story. Transitivity system, a framework of Halliday's Systemic Functional Linguistics (SFL), is used as an analytical tool. The data are gathered from the short story entitled “Day of the Dead”. This study employs qualitative descriptive analysis incorporating SFL into the methodology and Transitivity system analysis. This study finds that the creator employs all six Process types of Transitivity i.e., Material, Mental, Relational, Behavioral, Existential, and Verbal Processes. In constructing meanings, the six Processes are manifested in the three elements of the story: orientation, sequence of events, and reorientation. The employment of the six Processes is as an effort to expose learner to the clause as representation completely, that is to provide learners with all possible represented experiences through Processes that may happen in the world. The dominant Process of Material becomes the characteristic of the text and meets the linguistic features of recount text.

Radio Silences: The ‘Kidnapped Voices’ and the Production of Political Memory in Colombia (1994–2018)

AbstractAfter being kidnapped by the FARC-EP guerrilla group in 1994, the Colombian war reporter Herbin Hoyos created the radio show Las Voces del Secuestro (roughly, The Kidnapped Voices). Every morning, for 24 years, the families of those abducted by the guerrilla group sent out public messages of remembrance, hoping that their loved ones, deep in the jungles of Colombia, would be able to hear the broadcasts on their radios. Although the show closed in 2018, its legacy lives on, not only in the collective memory of many Colombians but also as an exhibition at the International Red Cross and Red Crescent Museum in Geneva (Switzerland). This article examines this show as a dispositif of power and knowledge that (re)produces a particular understanding of law, justice and memory. The show was used by far-right actors in Colombia to mobilise against the recent (2016) peace process – its crown jewel, the Special Jurisdiction for Peace (JEP). As the JEP tackles the question of the FARC-EP kidnapping through its macro-case 01, the shadow of the Voces looms large over Colombia's transitional justice system. In the longest non-international armed conflict in Latin America, even radio waves served the continuation of war by other means.

Surah Al Mujadalah Translation and Discourse Learning in Higher Education: A Systemic Functional Perspective

The main topic in this study is the system of transitivity and modality translation of Al-Quran Al-Mujadalah, and its relevance to the context of learning in higher education, with the goals of 1) determining the system of transitivity and modality, and 2) knowing the type of process and modalities that dominates and determines the relevance of the research on learning discourse in college. The method employed is a qualitative descriptive theory, which is based on Systemic Functional Linguistics. Documentation and records were used to collect data. The data was analyzed using the clause identification method, and the data were analyzed using the described method. According to the findings, the transitivity system as Al-Mujadalah verses 11 is process materials 4 (67 percent), relational identification process as many as 1 (16 percent), behavioral process 1 (16 percent). The shapes of modalities are probability, obligation, and usuality. The dominant of transitivity is a material process and the dominant modality is an obligation. In the context of higher education, discourse learning is not only about analyzing the text i.e Quran but also about the urgency of the message based on that surah translation.

The rights of nature and the human right to nature: an overview of the European legal system and challenges for the ecological transition

Introduction: The recognition of the Rights of Nature has been established though several constitutional, legislative, and judicial enactments, which aim to provide legal protection for non-humans’ entities and natural systems. Although some countries have made progress in recognizing the rights of nature, the prevailing assumption remains that nature is a resource to be exploited for human benefit. In the context of ecological transition debates, it is important to understand how the European legal system perceives Nature and its rights. Achieving a significant shift in legal and cultural norms that prioritize nature’s protection may be challenging.Methods: This paper reports on research conducted in a sample of 6 countries within the PHOENIX consortium, a European H2020 project that aims to develop participatory methodologies and democratic innovations to facilitate the ecological transition as envisioned by the European Green Deal, whose objective was to find out how these countries embodied the Rights of nature into their legal systems, both at constitutional level and at the level of environmental and related laws and policies.Results: The results indicate that in legislative terms, concepts of nature are absent, and instead, the term environment or natural resources are used. Furthermore, rights of nature are rarely recognized in all countries, with anthropocentric and in instrumental views prevailing. In contrast, the human right to Nature is widely recognized in all countries, referring to the right of all individuals to access to and live in a healthy environment.Discussion: Despite the importance of the human right to Nature as a matter of equity and justice, failure to recognise the rights of nature and protect/respect its limits may constitute a potential barrier to ecological transition.

Long-term data prove useful to keep track of non-indigenous seaweed fate

The Mar Piccolo of Taranto (southern Italy, Mediterranean Sea), a site of the European LTER network, is a transitional water system, where a century-old intensive mussel farming activity has been carried out, together with an intense import-export business of bivalve mollusks. Previous studies showed that this basin is third for NIS seaweed introduction in the Mediterranean Sea, after the Thau Lagoon and the Venice Lagoon. The present paper deals with the results of 11-year monitoring activity on non-indigenous species (NIS) of seaweeds, which was performed in the Mar Piccolo. In the studied period (2011–2021), two different time frames (i.e., 2011–2015 and 2016–2021) were considered, since they were based on a different number of sampling sites. To investigate spatial and temporal differences in the seaweed assemblage, a multivariate analysis was performed considering the NIS and the most important native species in terms of temporal occurrence. Fourteen NIS were recorded in total in the Mar Piccolo of Taranto during this period, with variable abundances among sites and years: nine species in the first time period, and thirteen species in the second one. Caulerpa cylindracea, recorded with negligible biomass in the first period, was absent in the second-period samplings. Molecular analyses confirmed the taxonomy of three species (i.e., Grateloupia minima, Neopyropia koreana, and Polysiphonia morrowii), previously identified only through morphological features. The most abundant species was Hypnea corona, which almost doubled its biomass in the second time period compared to the first one. Three species (i.e., Caulacanthus okamurae, G. minima, and P. morrowii) increased their biomass by an order of magnitude in the second time period. No significant differences were found over years. Site 1 resulted in significant differences among the sites and different seasonal pattern occurred among the investigated sites. No significant long-term changes occurred in the seaweed assemblages, suggesting the absence of strong disturbances due to the settlement of NIS.

Domain-Independent Dynamic Programming (Student Abstract)

In my dissertation, I will propose Domain-Independent Dynamic Programming (DIDP), a novel model-based paradigm for combinatorial optimization (CO) based on dynamic programming (DP). In DIDP, a problem is first formulated as a declarative DP model and then solved by a general-purpose solver. The goal of my dissertation is to develop an algorithm-independent modeling formalism to define a DP model and general-purpose solvers for it and demonstrate that DIDP is promising for CO in practice. In particular, I will propose a modeling formalism based on a state transition system and heuristic search solvers for it.

Improved Exploration of the Bench Transition System in Parallel Greedy Best First Search

While parallelization of A* is fairly well-understood, parallelization of GBFS has been much less understood. Recent work has proposed PUHF, a parallel GBFS which restricts search to exploration of the Bench Transition System (BTS), which is the set of states that can be expanded by GBFS under some tie-breaking policy. However, PUHF causes threads to spend much of the time waiting so that only states which are guaranteed to be in the BTS are expanded. We propose improvements to PUHF which significantly reduce idle time and allow more rapid exploration of the BTS, resulting in better search performance.

Fuzzy Bisimulations for Nondeterministic Fuzzy Transition Systems

Bisimulations are established forms of behavioral equivalences for discrete event systems. Recently, bisimulations have been introduced to fuzzy transition systems (FTSs) and developed quickly. Relational lifting by using weight functions is one of the most used methods in bisimulation research, which lifts a crisp relation on the state spaces to a crisp relation on the distributions of state spaces of FTSs. This paper proposes a method, called fuzzy relational lifting method, via fuzzy similarity measures induced by residua (implications) in complete residuated lattices. In contrast with the existing method, fuzzy relational lifting method relaxes the conditions of lifting relation by using weight functions and is a generalization of the method. Some properties of fuzzy lifting operation are presented. Based on the fuzzy lifting operation, a fuzzy bisimulation for nondeterministic fuzzy transition systems (NFTSs) is introduced, which is much more natural and robust than some behavioral measures, and can measure the degree of similarity between any two states which are deemed to be equivalent intuitively but simply distinguished by other behavioral measures. Then some properties of fuzzy bisimulations are provided. Moreover, a fixedpoint characterization of fuzzy bisimulations is given and the greatest fuzzy bisimulation is computed. Finally, a real-valued logic is introduced to characterize fuzzy bisimulations over Godel algebra.

N2 Use in Perennial Swards Intercropped with Young Poplars, Clone I-214 (Populus × euramericana (Dode) Guinier), in the Mediterranean Area under Rainfed Conditions

Intercropping perennial legumes with trees can reduce Nitrogen (N) losses, due to the high amount of N accumulated in stable forms in the soil and permanent soil cover during the whole year. Although N cycling improvement in mature agroforestry systems (AFS) was well documented, there is a lack of knowledge regarding systems in transition to AF. In this work, we studied the association of two perennial forage crops, namely ryegrass (Lolium multiflorum Lam.) and sulla (Hedysarum coronarium L.), with 1-year old poplars, to evaluate: (i) the agronomic performance of sulla and ryegrass with vs. without intercropped poplar trees; (ii) the N-fixing ability of sulla in association with trees; (iii) the N transfer effect from sulla and growth promoting effect on poplar; and finally (iv) the nitrate leaching reduction due to the presence of poplar trees associated to forage crops. The layout was arranged in a two-factor randomized complete blocks design (RCB) with three replicates. The first factor tested (crop species) implied two different swards, namely sulla and ryegrass. The second factor (cropping system) included two different systems: PAST i.e., a pastoral system without trees, and SIPAST, i.e., a silvo-pastoral system with one poplar tree row beside the sward. Sulla resulted more productive than ryegrass when associated with trees (+35%). No clear trend was observed about the tree influence on N-fixation in sulla, but the amount of N fixed resulted higher in in sulla grown in the SIPAST near the trees (+35%). Poplar plants, even in the first year after planting, resulted effective yet in reducing the nitrate flux from the crops towards ditches. Further investigations are needed to study other swards in young AF and better understand the N dynamics; in particular, it could be worth to assess the nutrient flux in the soil solution.

Agri-food systems in sustainability transition: a systematic literature review on recent developments on the use of the multi-level perspective

A sustainability transition (ST) of the agri-food system (AFS) is necessary due to manifold environmental and social exigencies. Scholars widely refer to the multi-level perspective (MLP) in the analysis of those transitions. The fast pace of articles covering AFS transitions, the evolving research on spaces between the three levels, and the consisting unclear conceptualization of MLP levels call for a systematic update on literature utilizing MLP in AFS articles covering ST. As a basis for reporting, this systematic literature review uses the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The search was conducted on the database Scopus encompassing the period from 2018 to 2022. After the selection procedure, 58 articles were included in the review. We extracted data based on a combination of a concept-driven and data-driven coding scheme. Qualitative research approaches outweigh and interrelated activities within the AFS are being analyzed, predominantly in the agricultural sectors. The focus lays on ongoing transitions. The concept of sustainability and its direction is considered as given (e.g., through the case lens), without further elaborations. The niche constitutes the most prominent object of study and scholars refer to rather socially innovative activities than technological innovations, providing distinct views on radicality and strategies to breakthrough. A space between niche and regime is being presented, with slightly distinct conceptualisations. Actors from both levels collaborate and exert transformative power. The regime is presented as static but also more vividly evolving views on the regime are demonstrated. The landscape receives the least attention and the focus lays on immaterial characteristics. Combinations of MLP with other frameworks have proven useful, for instance, regarding elaborations on the agency on the landscape level. Generally, an unclear conceptualization of regime and landscape persists, lacking a theoretical elaboration. Further research applying MLP should aim for a deeper examination of its theoretical construct, especially in terms of regime and landscape. More quantitative or mixed-methods research could supplement the current dominating qualitative approaches by testing and validating qualitatively constructed theories and phenomena.

Nanozymes with Peroxidase-like Activity for Ferroptosis-Driven Biocatalytic Nanotherapeutics of Glioblastoma Cancer: 2D and 3D Spheroids Models.

Glioblastoma (GBM) is the most common primary brain cancer in adults. Despite the remarkable advancements in recent years in the realm of cancer diagnosis and therapy, regrettably, GBM remains the most lethal form of brain cancer. In this view, the fascinating area of nanotechnology has emerged as an innovative strategy for developing novel nanomaterials for cancer nanomedicine, such as artificial enzymes, termed nanozymes, with intrinsic enzyme-like activities. Therefore, this study reports for the first time the design, synthesis, and extensive characterization of innovative colloidal nanostructures made of cobalt-doped iron oxide nanoparticles chemically stabilized by a carboxymethylcellulose capping ligand (i.e., Co-MION), creating a peroxidase-like (POD) nanozyme for biocatalytically killing GBM cancer cells. These nanoconjugates were produced using a strictly green aqueous process under mild conditions to create non-toxic bioengineered nanotherapeutics against GBM cells. The nanozyme (Co-MION) showed a magnetite inorganic crystalline core with a uniform spherical morphology (diameter, 2R = 6-7 nm) stabilized by the CMC biopolymer, producing a hydrodynamic diameter (HD) of 41-52 nm and a negatively charged surface (ZP~-50 mV). Thus, we created supramolecular water-dispersible colloidal nanostructures composed of an inorganic core (Cox-MION) and a surrounding biopolymer shell (CMC). The nanozymes confirmed the cytotoxicity evaluated by an MTT bioassay using a 2D culture in vitro of U87 brain cancer cells, which was concentration-dependent and boosted by increasing the cobalt-doping content in the nanosystems. Additionally, the results confirmed that the lethality of U87 brain cancer cells was predominantly caused by the production of toxic cell-damaging reactive oxygen species (ROS) through the in situ generation of hydroxyl radicals (·OH) by the peroxidase-like activity displayed by nanozymes. Thus, the nanozymes induced apoptosis (i.e., programmed cell death) and ferroptosis (i.e., lipid peroxidation) pathways by intracellular biocatalytic enzyme-like activity. More importantly, based on the 3D spheroids model, these nanozymes inhibited tumor growth and remarkably reduced the malignant tumor volume after the nanotherapeutic treatment (ΔV~40%). The kinetics of the anticancer activity of these novel nanotherapeutic agents decreased with the time of incubation of the GBM 3D models, indicating a similar trend commonly observed in tumor microenvironments (TMEs). Furthermore, the results demonstrated that the 2D in vitro model overestimated the relative efficiency of the anticancer agents (i.e., nanozymes and the DOX drug) compared to the 3D spheroid models. These findings are notable as they evidenced that the 3D spheroid model resembles more precisely the TME of "real" brain cancer tumors in patients than 2D cell cultures. Thus, based on our groundwork, 3D tumor spheroid models might be able to offer transitional systems between conventional 2D cell cultures and complex biological in vivo models for evaluating anticancer agents more precisely. These nanotherapeutics offer a wide avenue of opportunities to develop innovative nanomedicines for fighting against cancerous tumors and reducing the frequency of severe side effects in conventionally applied chemotherapy-based treatments.

Temperature-Induced Nanostructure Transition for Supramolecular Gelation in Water.

Thermogel is an injectable biomaterial that functions at body temperatures due to the ease of the sol-to-gel transition. However, most conventional physically cross-linked thermogels generally have relatively low stiffness, which limits various biomedical applications, particularly for stem-cell-based studies. While chemical cross-linking through double-network (DN) structures can increase the stiffness of the hydrogel, they generally lack injectable and thermoresponsive properties due to strong covalent bonds between molecules. To address this challenge, we have developed a temperature-induced nanostructure transition (TINT) system for preparing physical DN supramolecular hydrogels. These hydrogels possess injectable, thermoreversible characteristics and relatively high storage modulus (G'), which increases ∼14-fold from 20 to 37 °C (body temperature). Our bottom-up strategy is based on the co-assembly of aromatic peptide (Ben-FF) and poly(ethylene glycol) (PEG) to form a thermogel at 37 °C through a nanofiber dissociation pathway that differs from the well-known micelle aggregation or polymer shrinkage mechanisms. Peptide molecules form helical packing and weak, noncovalent interactions with PEG, resulting in co-assembled metastable nanofibers. Thermal perturbation initiates lateral dissociation of nanofibers into extensively cross-linked DN nanostructures and subsequent hydrogelation (ΔG = -13.32 kJ/mol). The TINT hydrogel is nontoxic to human mesenchymal stem cells and supports enhanced cell adhesion, suggesting the potential of this strategy in the applications of tissue engineering and regenerative medicine.

Fixpoint Theory -- Upside Down

Knaster-Tarski's theorem, characterising the greatest fixpoint of a monotone function over a complete lattice as the largest post-fixpoint, naturally leads to the so-called coinduction proof principle for showing that some element is below the greatest fixpoint (e.g., for providing bisimilarity witnesses). The dual principle, used for showing that an element is above the least fixpoint, is related to inductive invariants. In this paper we provide proof rules which are similar in spirit but for showing that an element is above the greatest fixpoint or, dually, below the least fixpoint. The theory is developed for non-expansive monotone functions on suitable lattices of the form $\mathbb{M}^Y$, where $Y$ is a finite set and $\mathbb{M}$ an MV-algebra, and it is based on the construction of (finitary) approximations of the original functions. We show that our theory applies to a wide range of examples, including termination probabilities, metric transition systems, behavioural distances for probabilistic automata and bisimilarity. Moreover it allows us to determine original algorithms for solving simple stochastic games.

IMR – 7th INDAM CONFERENCE PAPER: Future of workplace design from a socio-technical perspective

Post-COVID-19, there is an ongoing discussion worldwide on the future of workplaces across organisations. This is a socio-technical system in transition, and we use a multi-level perspective (MLP) to identify the changing elements. We perform discourse analysis on the social media platform to gather stakeholders’ perspectives on the workplace to identify (a) changing dimensions of the workplace; (b) emerging challenges; (c) the necessity for adoption of new technologies; and (d) learnings from the pandemic with respect to the workplace. We propose a conceptual model through theories of socio-technical perspectives that shall inform practice on the design of workplace policy.

A Unified Logical Framework for Reasoning about Deontic Properties of Actions and States

This paper studies some normative relations that hold between actions, their preconditions and their effects, with particular attention to connecting what are often called ‘ought to be’ norms with ‘ought to do’ norms. We use a formal model based on a form of transition system called a ‘coloured labelled transition system’ (coloured LTS) introduced in a series of papers by Sergot and Craven. Those works have variously presented a formalism (an ‘action language’) nC+ for defining and computing with a (coloured) LTS, and another, separate formalism, a modal language interpreted on a (coloured) LTS used to express its properties. We consolidate these two strands. Instead of specifying the obligatory and prohibited states and transitions as part of the construction of a coloured LTS as in nC+, we represent norms in the modal language and use those to construct a coloured LTS from a given regular (uncoloured) one. We also show how connections between norms on states and norms on transitions previously treated as fixed constraints of a coloured LTS can instead be defined within the modal language used for representing norms.

Representing Processes in Toni Morrison's "Sula": A Critical Stylistic Analysis

Ideology is not confined to news articles, political debates and speeches, or even promotional advertisements, it can be found in all types of texts, including literary texts. Literary language has become one of the most effective techniques used by writers to convey a sublime rhetorically-oriented message or an idea to readers. Although Toni Morrison is one of the most renowned authors of fiction in today's world, yet only a small number of studies have addressed her novels from a linguistic perspective. Hence, the study in hand aims to examine how the exploitation of linguistic resources—verbs, in particular—helps to construct certain ideologies. The study applies one of Jeffries' (2010) tools of analysis, namely 'Representing Actions/Events/States', informed by Simpson's (2004) framework of the transitivity system. The type and frequency of the verbal process and the linguistic context in which those processes are produced construct different identities for the character in question.
