Research on the Rules of Right Restriction under the Protection Regulations for New Varieties of Plants: Taking Farmers' Own Seed Saving as an Example

The protection of intellectual property for the new varieties of plants aligns with the needs of contemporary development, yet it also creates conflicts with the traditional practices of farmers who save their own seeds. Farmers' right to save their own seeds is a natural entitlement, and the clash between the public interest in this practice and the rights associated with new plant varieties remains a derivative issue of the intellectual property enclosure movement. The starting point of the problem lies in reconciling the private nature of intellectual property rights with public interests, while its resolution depends on the adaptation of limitations and exceptions within intellectual property law. Under the protection of intellectual property rights for new plant varieties, farmers face difficulties in determining reasonable boundaries for seed saving. At the legal level, it is necessary to recognize the legitimacy of farmers’ seed-saving practices and reasonably define such activities; at the practical level, it is feasible to incorporate relevant systems from copyright law, establish a compensation mechanism, and set up collective management organizations for seed-saving fees to rebalance the interests of relevant parties.

Effects of increased availability and economic incentives on preadolescents’ healthier beverages choices: An experimental study

This field experimental study examined how increased availability and economic incentives for healthier beverages affect preadolescents' actual healthier beverage choices in a real-world setting. In addition, the impact of preadolescents’ descriptive norm towards healthier beverages, price awareness and parental restrictive rules regarding beverage consumption were explored. During the experiment, preadolescents could independently buy two beverages from an assortment with a total of eight beverages. A 2x2 between-subjects design was used, manipulating the presence of increased availability of healthier beverages and economic incentives (taxes for unhealthier beverages and subsidies for healthier beverages). A total of 305 preadolescents between 8 and 14 years old (M = 10.18, SD = 1.74) participated, each accompanied by one of their respective parents. Results showed that preadolescents were more likely to choose healthier beverages and perceived a higher descriptive norm towards healthier beverages when the assortment included increased relative availability of healthier beverages. Economic incentives and price awareness did not impact healthier beverage choices. Preadolescents were less likely to choose healthier beverages when parents reported higher levels of restrictive rules regarding beverage consumption. Results of the study suggest that increasing relative availability of healthier options could be a promising intervention strategy to support preadolescents in making healthier choices.

On $3$-generated axial algebras of Jordan type $\frac{1}{2}$

Axial algebras of Jordan type $\eta$ are a special type of commutative non-associative algebras. They are generated by idempotents whose adjoint operators have the minimal polynomial dividing $(x-1)x(x-\eta)$, where $\eta$ is a fixed value that is not equal to $0$ or $1$. These algebras have restrictive multiplication rules that generalize the Peirce decomposition for idempotents in Jordan algebras. A universal $3$-generated algebra of Jordan type $\frac{1}{2}$ as an algebra with $4$ parameters was constructed by I. Gorshkov and A. Staroletov. Depending on the value of the parameter, the universal algebra may contain a non-trivial form radical. In this paper, we describe all semisimple $3$-generated algebras of Jordan type $\frac{1}{2}$ over a quadratically closed field.

Ethnographic Study Found School Library is a Safe Refuge of Solitude for French Urban Middle School Students

A Review of: Joing, I. (2023). The school library: An important place for adolescents’ well-being. An ethnographic experience in a French middle school. Journal of Library Administration, 63(6), 777-796. https://doi.org/10.1080/01930826.2023.2240192 Objective – To understand the role of school libraries in middle school students’ well-being. Design – Ethnographic study consisting of overt participant observation, semi-structured interviews, and a written questionnaire. Setting – An urban middle school in northern France between November 2017 and April 2018. Subjects –Students from 10 to 15 years of age and selected school personnel. Methods – Students from three randomly selected classes were invited to complete the questionnaire, and quantifiable responses were summarized using descriptive statistics. Other materials collected during the five-month study period, including the researcher’s field journal, interview transcripts, and qualitative questionnaire responses, were analyzed using grounded theory-informed open, axial, and selective coding to discern students’ perception of the library. Main Results – The majority of the 95 students who completed the questionnaire viewed the library as a safe place associated with positive school experiences. However, these favorable impressions gradually decreased as students progressed in their studies, with senior (fourth-year) respondents reporting the lowest positive-to-negative experience ratio, at 1.1 to 1. Thematic clusters that emerged from coding of the rest of study materials further supported these findings, showing that students perceived the library to be both (a) a physical shelter from harsh winter elements during recess or lunch, and (b) a psychological refuge for solitude and peace from negative peer interactions. Nonetheless, (c) limited and unreliable library hours and (d) restrictive rules concerning noise and space access appeared to erode these positive associations over time. Senior students also expressed (e) the desire for more library or general school spaces dedicated to group work. Conclusion – Findings from this ethnographic study highlighted different ways library space contributed to students’ sense of well-being. The study also uncovered some shortcomings in space management that contributed to students’ declining library use and positive perception over the course of middle school. The researcher recommended extending library hours and expanding the diversity of library activities to ensure the space would serve as a welcoming environment not only for students seeking solitude, but also for those desiring more peer collaborations and social connections.

EVOLVING MASCULINITY: A STUDY OF BODY POSITIVITY IN MEN

If we are to understand why it is so rare and what the future holds, the topic of body positivity in males has evolved into a complex one that requires discussion. Men frequently encounter irrational expectations that result in body dissatisfaction and a low sense of self- worth in todays society, when media representations of the ideal male form and gender stereotypes predominate. The medias depiction of the ideal male body, which is characterized by muscular proportions and low body fat, is a major reason man are not positive about their bodies. These restrictive rules put pressure on men to conform, which can cause body dissatisfaction and a decrease in self- esteem. Furthermore, the traditional gender roles of men and women indicate the idea that men should be portrayed as strong, stoic, and emotionally controlled, which discourages open conversations about body image issues and the need for assistance. The psychological and mental toll it takes on a person can cause various issues in men, both physically and mentally. It may be caused by constant pressure to meet these standards. Feelings of inadequacy and dissatisfaction can also be a contributing factor. It can lead to chronic problems in life. The most important part of maintaining a healthy state of mind is managing these body image concerns. In men, theres a lot of ways to support positive body image. Through education and awareness programs, these programs challenge harmful beauty norms and promote positive body image. Resources and workshops to help men reject outdated ideas and accepting body positivity need to be provided by schools, organizations, and communities. Its critical that we dismantle obstacles when it comes to mens body image. The secret to building an environment where guys can talk about their issues and receive assistance without fear of judgment is to have open dialogues about topics like how they feel about their bodies and mental health. Social media can also be a useful tool for promoting campaigns that celebrate the diversity of peoples bodies and for sharing fascinating tales that people can relate to.

Multistakeholder Perspectives on the Determinants of Family Fundamental Movement Skills Practice: A Qualitative Systematic Review.

Childhood obesity is a significant public health crisis that is exposing children to associated morbidities and premature mortality. However, parents can positively influence physical activity trajectories and improve health outcomes by nurturing fundamental movement skills (FMS) in children. This is the first study to explore the determinants of family FMS practice via a systematic synthesis of qualitative evidence. Keyword searches were completed in SPORTDiscus, PubMed, Scopus, Web of Science, and Embase. Studies that offered perspectives relating to influences on the FMS of 2-6-year-old children in the family context via qualitative approaches, including visual methodologies that provided an important voice to children, were included. A thematic analysis was used to establish key themes. The emergent themes included parent knowledge and beliefs, self-efficacy of parents to teach, and the home environment. Parents often undervalued FMS and lacked the self-efficacy to teach due to poor understanding, conflicting priorities, and multifaceted societal influences. Children preferred autonomous play and socialisation but were negatively influenced by technology and restrictive household rules. Greater knowledge exchange between stakeholders is necessary to empower parents and enhance FMS application at home. More community initiatives could facilitate greater access to outdoor spaces, facilities, and equipment, which may improve family engagement with FMS.

Criministrative Law

Textual analyses of child welfare laws, joined by extensive textual and legal analyses of case law, reveal how the “dance” between the administrative and the criminal in child protective services (CPS) is rooted in the individualized perception of poverty. This individualization, which forms the bedrock of the capitalist American welfare state, promotes the fragmentation of the family unit. Building on individualized perception and reifying it, child welfare laws and practices are neither purely administrative nor criminal, but “criministrative.” As such, they serve as a legal shield for the State in its attemptsto ensure child welfare; the State refuses to provide protections available in traditional criminal contexts to families involved in CPS investigations, while simultaneously enjoying administrative courts’ less restrictive evidentiary rules. This Article follows the thread of individualized surveillance embedded in the law, starting with the conflation of “abuse” and “neglect.” This Article proposes three solution pathways, building from practicalto theoretical: divorcing neglect from abuse, adopting a Poverty Aware Paradigm, and developing a theoretical framework for an institutionalized “benevolent gaze.” This Article joins growing discussions in critical legal scholarship concerning the carceral nature of the welfare state and the relationship between care and punishment inthe United States. This Article adds a further dimension to these discussions by asserting that child welfare law is more aptly described as criministrative law, and by exposing the rootedness of the individualized perception of poverty in the organizing concepts of the child welfare system. Finally, this Article calls for a reconstruction of the legal treatment of children who are at risk of harms caused by poverty. If left unchecked, criministrative law will continue to inflict harm upon parents, thus harming the very children that CPS is meant to protect.

International fiscal rules and domestic support for austerity

In recent decades, fiscal integration in Europe has manifested through restrictive rules. However, the consolidation of public finances often encounters citizens’ resistance. International obligations can raise public support for costly domestic policies that are consistent with the obligations’ terms, but can European fiscal pledges influence public opinion and boost support for austerity? I fielded an original survey experiment in Italy and manipulated information about the existence of a new fiscal rule, national or European, mandating austerity measures. In stark contrast with extant research, I find no evidence that the source of the fiscal rule matters when measuring respondents’ support for austerity. This result suggests that the effect of international pledges on garnering public support for costly domestic measures wanes if these measures directly burden citizens’ financial well-being. Moreover, relinquishing fiscal autonomy in favour of new European rules appears unlikely to aid politicians in winning public endorsement for an austerity agenda.

Specification and Verification for Unrestricted Algebraic Effects and Handling

Programming with user-defined effects and effect handlers has many practical use cases involving imperative effects. Additionally, it is natural and powerful to use multi-shot effect handlers for non-deterministic or probabilistic programs that allow backtracking to compute a comprehensive outcome. Existing works for verifying effect handlers are restricted in one of three ways: i) permitting multi-shot continuations under pure setting; ii) allowing heap manipulation for only one-shot continuations; or iii) allowing multi-shot continuations with heap-manipulation but under a restricted frame rule. This work proposes a novel calculus called Effectful Specification Logic (ESL) to support unrestricted effect handlers, where zero-/one-/multi-shot continuations can co-exist with imperative effects and higher-order constructs. ESL captures behaviors in stages, and provides precise models to support invoked effects, handlers and continuations. To show its feasibility, we prototype an automated verification system for this novel specification logic, prove its soundness, report on useful case studies, and present experimental results. With this proposal, we have provided an extended specification logic that is capable of modeling arbitrary imperative higher-order programs with algebraic effects and continuation-enabled handlers.

Data-driven ergonomic assessment of construction workers

Automating ergonomic assessment improves both objectivity and cost-effectiveness. However, existing ergonomic scales remain susceptible to inaccuracy and insensitivity when assessing diversified construction activities. This susceptibility stems from the unreliable ranges, sharp boundaries, and oversimplified binary rules within conventional joint-level assessment rules, coupled with the restricted transformation rules to integer input/output. This paper presents a data-driven ergonomic assessment method grounded in statistical data from Construction Motion Data Library (CML) dataset, comprising: 1) Developing joint-level scoring models to primarily improve accuracy through leveraging Heuristics Gaussian Cloud Transformation (H-GCT), and 2) Designing fuzzy inference mechanism to enhance sensitivity through retaining risk information during transformation across levels. Subsequently, a three-step validation confirms accurate risk identification, sensitive risk feedback, and positive correlation with previous methods, contributing to occupational health and safety management. Future research could enhance the method by expanding the pose dataset, recruiting more participants, and refining the 3D pose estimation.

Optimization of Welded Joints under Fatigue Loadings

In this paper, the notch effect in weldments has been investigated, and the optimal configuration of different types of welded joints has been analysed using the implicit gradient approach. By considering this implicit gradient method, it is possible to calculate the effective stress related to fatigue damage, with the effective stress being a continuous scalar function of the real stress tensor components, even in the presence of sharp edges. Hence, the search for the optimal configuration that maximises fatigue life can be tackled as the condition of minimum effective stress obtained by changing the weld shape and geometrical parameters. Both load-carrying cruciform joints and spot welds made of steel have been considered. The structural details have been studied by modelling actual shapes without any geometric simplification. Moreover, the same numerical procedure has been considered independently of the size, shape or load condition without imposing restrictive rules on the FE mesh.

The Integration of ICT in ELT of Pre-Service Teacher Professional Education (PPG) Students

Student teachers are expected to take advantage the use of technology for teaching process. This study aims to investigate the ICT tools used by Pre-service English Teachers who are also PPG students to achieve their learning goals in teaching English during their Teaching Practicum (PPL), how they integrate these ICT tools evaluated by TPACK and SAMR framework, and examine the obstacles. This current study was descriptive qualitative research. In this research design, the data was gathered by means of document analysis, semi-structured interview and observation. The participants were five Pre-Service Teacher Professional Education (PPG) Students majoring English Education Batch 2 academic year 2022/2023 in one of university in Yogyakarta, who represented three school levels (SMP, SMA and SMK). The data were in three distinct stages: reduction or condensation, data display, and conclusion drawing or verification. The result shows that (1) variety of ICT tools are used to achieve the learning goals, they are Google Form, Google Docs, WhatsApp, Canva, Blooket, Bamboozle, WordWall, Kahoot, Quizizz, YouTube, and GimKit. These tools are selected based on the learning needs, students’ need, students’ preferences, learning objectives, availability of facility, and possible challenges. (2) The activities that integrating ICT tools majority are in augmented level of SAMR. While the pre-services teachers’ TPACK is effectively help them in integrating ICT tool to enhance the quality of learning, but still need optimization. (3) There are three main obstacles faced by the teachers; which come from the technical problems, teachers’ TPACK, and students’ problem. Technical problems covers the lack of internet access, insufficient devices, and restrictive school rules. Teachers’ challenge on their TPACK includes the selection of suitable tools, the time management in integrating ICT tools, and the struggle to keep up with the rapid development of technology. The students face no significant problems, yet sometimes the negligence of the task arises as they become too attached with the ICT tools.

The Shengen Agreement and European Integration

Since the conclusion of the Schengen Agreement, the importance of asylum and migration policy for the EU has increased significantly. "Schengen" constitutes an essential element of the freedom of movement formulated by the European Union as the central objective of its policy, i.e. the unrestricted movement of all citizens between EU member states and the freedom of establishment granted therein. Cooperation of EU member states is mainly based on the development of restrictive rules for a common border and visa policy, as well as cooperation to limit asylum immigration. Since the 1990s, tools to improve border controls have mainly consisted of regulations declaring other states “safe third countries” and “safe countries of origin and transit,” making them responsible for asylum procedures. Such regulations have often been supported by treaties with countries of origin or transit, which have not always been willing or able to guarantee human rights. Member states in their domestic policies have extensive debates and disagreements on the direction of asylum policy. While some states want to protect the rights of those seeking protection, others prioritize controlling and limiting immigration. In the early 2000s, the EU decided on minimum standards for national asylum legislation and asylum procedures, not in the interests of those seeking protection, but mainly to prevent those seeking protection from moving to find better conditions in other countries according to very different standards. . However, minimum standards have remained limited by national discretion, so differences in procedures and benefits afforded to recognized asylum seekers and refugees remain extremely wide.

Controversy of Copyright Application and the China Plan of Metaverse Products

Abstract The controversy over copyright theory in the metaverse scenario mainly arises from the issue of copyrightability of metaverse products. Metaverse products have initially reached the standard of originality and formally conform to the dichotomy of thought and expression, however, the incompatibility of object types has led to controversy over its copyright theory. In addition, the three types of disputes and difficulties based on the “behavior” element: original acquisition and derivative acquisition, original products and derivative products, and public domain and private domain, are not just copyright disputes in the metaverse scene, but also a difficult problem that the copyright system cannot reconcile. In this regard, this article draws on overseas experience, introduces the theory of copyright expansion, and combines the needs of China’s judicial practice and China’s national conditions, trying to solve the copyright legal issues in the metaverse scenario one by one through the “source of communication” theory, behavior restriction theory and interest game theory, and propose China’s response to the problems caused by the generalization of digital technology from the three dimensions of originality standard identification, object classification, and rights restriction rules.

Multiparticle Factorization and the Rigidity of String Theory.

Is string theory uniquely determined by self-consistency? Causality and unitarity seemingly permit a multitude of putative deformations, at least at the level of two-to-two scattering. Motivated by this question, we initiate a systematic exploration of the constraints on scattering from higher-point factorization, which imposes extraordinarily restrictive sum rules on the residues and spectra defined by a given amplitude. These bounds handily exclude several proposed deformations of the string: the simplest "bespoke" amplitudes with tunable masses and a family of modified string integrands from "binary geometry." While the string itself passes all tests, our formalism directly extracts the three-point amplitudes for the low-lying string modes without the aid of worldsheet vertex operators.

Exercise addiction symptoms and mental health during the forced exercises deprivation in greatest COVID-19 pandemic restrictions in Poland.

The paper describes the relationship between the symptoms of exercise addiction, behavioral strategies in situations of limited workout possibilities and mental health state in exercising individuals. The study included 391 participants, 286 women (73.1%) and 105 men (26.9%), aged 18 to 68 years. The respondents were surveyed online after 17-19 days of barriers to routine training due to greatest COVID-19 restrictions in Poland. Subjects completed the Exercise Dependence Scale, General Health Questionnaire - 28 (GHQ-28) and questionnaires enabling the collection of demographic and clinical data as well as data related to exercise behaviors. The variables related to exercise addiction and some related to behavioral changes are predictors of mental health, especially in terms of anxiety, insomnia and somatic symptoms. All the introduced variables accounted for 27.4% to 43.7% of the variation in the mental health status of the subjects, depending on GHQ subscales. Breaking the restriction rules by outdoor training protected against symptoms of psychological disorders, especially in relation to somatic symptoms (Beta = -0.23; p< 0.001). Individual assessment of stress induction in a given situation was a predictor of results in all GHQ subscales, which was the strongest for symptoms of anxiety and insomnia (Beta = 0.37; p< 0.001). Individuals with features of exercise addiction are at risk of deterioration of their well-being during forced abstinence. In addition, the subjective level of stress induction in a given situation is an important determinant that conditions psychological well-being, especially the aggravation of depressive symptoms. People who ignore restrictions and have low levels of stress, experience lower psychological costs.

Electrochemical diagrams showing equilibrium cathodic phases and their compositions as function of electrolyte composition and type of alloy phase diagram

In this paper the dependence of the elemental and phase compositions of the binary A-B cathodic deposits are computed by constructing “Electrochemical Diagrams”, abbreviated as ECDs, which potentially have a high practical significance. An ECD shows phases and compositions of cathodic alloy products as function of electrolyte composition at fixed temperature, pressure and at low current density upon galvano-static electrochemical co-deposition of components A-B from the same electrolyte on an inert cathode. The following rules are established here to construct the ECDs for binary A-B alloys: i). among all possible cathodic phases the one will be electrodeposited that provides the least negative cathodic deposition potential, ii). two or three (but not four or more) phases can be co-deposited on the cathode if their equilibrium cathodic potentials are equal and are the least negative among all possible cathodic phases, iii). the equilibrium compositions of solid and liquid A-B alloys that form on the cathode can be found from the condition of equality of the partial equilibrium cathodic potentials of components A and B. Based on the above three rules, ECDs are constructed for some basic types of binary equilibrium alloy phase diagrams with the composition of the alloy on its y-axes as function of the ionic composition of the electrolyte on its x-axes. In all cases the clear connection is shown between the ECDs and their corresponding alloy phase diagrams. The following geometric features are established for ECDs: i). solution phases are characterized by continuous curves, ii). phases of fixed compositions are characterized by horizontal lines, iii). two-phase mixtures are characterized by vertical lines, iv). three-phase equilibria are characterized by single points along the vertical lines corresponding to the two-phase equilibria of the parent phases of the third phase. It is shown that the restricted phase rule of Gibbs (= the maximum number of coexisting phases = the number of independent components + 1) is valid also for the ECDs. As examples, ECDs are calculated for the Ni-Co system and for the Ti-B system and good agreement is found between these calculated diagrams and the experimental data.

Determined to be resilient: Analysis of the well-being of people with disabilities (People of determination) in Abu Dhabi during the COVID-19 pandemic

This study examines whether people with disabilities report different COVID-19-related challenges and adverse impacts on their psychological well-being compared to people without disabilities. During the pandemic, most people, including those with disabilities, faced strict rules of movement restriction and isolation that might have resulted in certain psychological feelings, challenges, and social reactions. Data were gathered through the 3rd cycle of the Abu Dhabi Quality of Life Survey conducted in 2021, which included 1,954 respondents who categorized themselves as having some disabilities. Through descriptive analysis, t-tests, and analysis of variance, this study indicated a significantly higher level of fear, loneliness, and stress among people with disabilities during the pandemic. There were also significant findings related to the impact of new technologies on the quality of life of people with disabilities. For all psychological wellbeing concerns, challenges, and reactions, significant differences were observed regarding gender, marital status, education attainment, nationality, and age of people with disabilities, but not to a large extent. The findings were discussed in light of international and regional literature and provided a resource for social policymakers to identify gaps in disability services. Finally, policy recommendations and future research directions were summarized and discussed, while the limitations of this study were acknowledged.

Getúlio Vargas and the Making of Restrictive Migratory Policies in Post-1930 Brazil

Following Brazil’s “great migration” period (1880–1930) came Getúlio Vargas’s rise to power, marking a radical historical rupture. From 1930 onwards, we observed the construction of a framework of restrictive rules aimed at controlling the entry and stay of foreigners in the country, including an ethnically differentiated management of flows. This article sought to cross-reference the new migratory policy, aimed at both new entries and immigrants already present in the territory, with the issue of race. To this end, it dealt with two groups of immigrants whose flows were directly impacted by the new policies (and by racism), but not in the same way: Japanese and Jews. The reflection also turned to the different experiences in each of the two groups between the candidates for immigration—in the face of the new barriers imposed on entry and those already living in Brazil in the face of the assimilationist measures adopted. Brazilian migration policies and state actions have been studied more often than the agency of immigrants. In this sense, the existing studies have focused more on the management of new flows than on the experience of immigrants already settled in the territory. The text, therefore, assumed a change of perspective, opting for a look “from below” in order to focus on both sides of the scales and the border. Finally, it examined the historiography that dealt with migration policy during the Vargas era and, more specifically, that which focused on Jewish and Japanese immigration.
