The contribution of episodic Long-term Memory to Working Memory for Bindings.
Authors: Bartsch Lea Maria , Oberauer Klaus
Published: June 2021

The present experiments support two conclusions about the capacity limit of working memory (WM). First, they provide evidence for the Binding Hypothesis, WM capacity is limited by interference between bindings but not items. Second, they show that episodic LTM contributes substantially to binding memory when the capacity of WM is stretched to the limit by larger set sizes. We tested immediate memory for sets of word-picture pairs. With increasing set size, memory for bindings declined more precipitously than memory for items, as predicted from the binding hypothesis. Yet, at higher set sizes performance was more stable than expected from a capacity limited memory, suggesting a contribution of episodic long-term memory (LTM) to circumvent the WM capacity limit. In support of that hypothesis, we show a double dissociation of contributions of WM and episodic LTM to binding memory: Performance at set sizes larger than 3 was specifically affected by proactive interference – but were immune to influences from a distractor-filled delay. In contrast, performance at set size 2 was unaffected by proactive interference but harmed by a distractor-filled delay.
Disbelief, Disengagement, Discontinuance, and Disaffiliation An Integrative Framework for the Study of Religious Deidentification
Authors: Van Tongeren Daryl R. , DeWall C. Nathan
Published: June 2021

Religion offers a powerful social identity. However, religious change is common across the lifespan, including some who leave religion altogether. Research on leaving religion has mostly been fragmented and failed to embrace a unified theory that captures the breadth of the extant research and appreciates the crucial nuances revealed by empirical findings. Toward that end, we adopt Saroglou’s (2011) classification of four dimensions of religiousness to introduce a conceptual model to explain the varieties of different research strands that have examined those leaving religion and integrate them into a unified theory of religious change. We explain how religious deidentification describes how one no longer identifies as religious, and this process can occur via disbelief, disengagement, discontinuance, and disaffiliation. We contend that religious and spiritual struggles are potential pathways by which deidentification may occur. Finally, we situate the work on religious deidentification among other related constructs and provide a brief framework for future research on the nonreligious experience.

Authors: Suwarta Suwarta , Hanafie Rita
Published: June 2021

The broiler chicken business is essential to providing national meat consumption in Indonesia. However, the business also faces a very significant management risk.  The purpose of this research is to study broiler farm management and the effect of its business management on the production and production risk. This research was conducted in Lamongan regency of East Java by interviewing broiler chicken farmers and using descriptive and multiple linear regression analysis. The results of the research show that the implementation of broiler farm management reached 73.48% of ideal situation, with planning reaching 67.64% ideal situation, 65.58% for ideal organizing, 84.18% for optimal direction, 74.43% for ideal coordination, and 77.58% for ideal control. Also, the management had a positive influence on the production of the broiler livestock business, with an elasticity of 0.700. The management had a negative effect on the risk of production of broiler livestock business with the elasticity of 0.237. Production risk was negatively affected by the number of chicks and the amount of feed. To provide support for breeders in their business, it is necessary to have a policy of low cost of broiler cultivation, especially the cost of chicks and feed, by setting DOC prices and cheap or cheaper feed. Besides, it is required to develop cooperation with companies using broiler primary products, as well as certain policies so that there will be businesses that use broiler primary products as their main ingredient.JEL Classification D13; Q02; Q12
Household finances and social comparison: Determinants of financial well-being in Indonesia
Authors: Ghina Aisyah Amatul , Sukarno Subiakto
Published: June 2021

To achieve a vision of sustainable financial well-being (FWB) in Indonesia, generating more knowledge in household behavior and FWB is pivotal. This study assesses the impact of household financial position and social comparison on individual FWB in Indonesia. Using the latest wave of Indonesia Family Life Survey (IFLS) dataset, subjective FWB assessed by questions on subjective prosperity, perceived current standard of living adequacy and perceived future standard of living. The empirical analysis shows that net wealth and total assets are also essential determinants and positively related to FWB along with income. On the contrary, though it is only found significant on the perceived current standard of living adequacy, the total debt level has a negative effect on FWB. The findings also confirm that socioeconomic and demographic factors also significantly affect FWB (e.g., being female and more educated has a positive effect on FWB). Furthermore, it also found that relative financial position (i.e., social comparison) has important roles in determining individuals' FWB level. Being above the reference group's average for a particular financial measure (i.e., income and total assets) has a positive effect on an individual's FWB. The findings of this study suggest for promoting financial education in the national school system starting senior high school to increase the level of financial well-being among young adult and people with lower educational attainment.JEL Classification C31; D14; I31

Prime numbers demystified
Authors: Ncube Artwell
Published: June 2021

The paper is the ultimate prime numbers algorithm that gets rid of the unneccessary mystery about prime numbers. All the numerous arithmetic series patterns observed between various prime numbers are clearly explained with an elegant "pattern of remainders". With this algorithm we prove that odd numbers too can make an Ulam spiral contrary to current ""proofs". At the end of the paper this author proves the relationship between a simple arithmetic series pattern and the Riehmann's prime numbers distribution equation. This paper would be important for encryption too. As an example, prime integer 1979 is expressed as 1.2.4.5.10.3.7.3.1.7.26.18.11.1. This makes even smaller primes useful for encryption as well.
Analysis of Environmental Impacts Caused by the Construction of Power Transmission Lines in Brazil
Authors: Reis Barros Igor , Pereira de Vasconcelos Raimundo
Published: June 2021

A country's energy production, transmission and distribution systems are directly linked to its technological advances and economic growth. In Brazil, the creation and expansion of several transmission lines are planned. Such ventures often come up against environmental aspects, as they advance over forest and conservation areas. In this context, the objective of this research was to study the main environmental impacts caused by the implementation of transmission lines in forest areas in order to have a better understanding of the subject, thus being able to minimize or extinguish them. After gathering information, it was found that most of the environmental impacts are due to the deforested area around the transmission lines, called the right of way, which creates a corridor that alters the vegetation. Other serious impacts are related to the type of foundation most used: the micropile, which uses a toxic stabilizing mud in its drilling. The results of this research can be used as a basis to minimize such impacts that can cause damage to the environment and delays in the construction of the lines.

Published: June 2021

The transmission of data and energy has been widely used over the past few centuries, but in a complex manner and at high cost. Gradually in order to simplify this process and reduce costs, important network cables have appeared, namely: twisted pair cables, coaxial cables, and fiberoptic cables. Thus, instead of various wires, a single cable has become necessary. Within this context, this study seeks to evaluate data transmission performance using two types of Ethernet cables, CAT E5 and CAT E6, in circuits with DS18B20 temperature sensors. The evaluation of the two cables was made by reducing their lengths by 10 meters every two weeks to find the length of cable which would ensure a reliable reading of the sensors for use in the research project entitled “The Evaluation of the Potential Use of Surface Geothermal Energy in the City of Dourados, MS”. The obtained data indicates that CAT E5 cables with lengths less than 70 meters ensure reliable readings close to the real value, while for CAT E6 Ethernet cables this takes place at lengths of less than 80 meters.

In this study, the influence of partial introduction as glass as fine aggregate on the composition of simple concrete is analyzed, considering that sand (fine aggregate currently used) has been used on a large scale in civil construction over the years and has been affecting the environment. The main objective of this research was to analyze the mechanical properties of concrete, partially replacing the natural sand with another fine aggregate made from glass residues, evaluating the behavior presented at the end of each test using different percentages of this material as fine aggregate in the concrete composition. From an experimental methodology that consisted of determining an object of study (concrete), selecting the variable that would possibly be able to influence it (glass powder) and defining the ways of controlling and observing the effects that the variable would produce on the object, an interpretation of how the mechanical properties of the glass powder that affect the performance of structural concrete is presented. The granulometry was subsequently analyzed, the tests carried out both in the fresh and hardened state of the concrete, and identified that the glass in a certain percentage proves to be viable. Finally, it can be concluded that the partial inclusion of glass affects the mechanical properties of structural concrete, and can present quite satisfactory results, both related to the environment, since the sand would not be used entirely as fine aggregate or in reaching a resistance suitable for its final use.

Published: June 2021

Connected speech is an everyday activity. We aimed to investigate whether connected speech can differentiate oral narrative production between adults with Alzheimer’s disease (AD; n = 24) and cognitively healthy older adults (n = 48). We used graph attributes analysis to represent connected speech. Participants produced oral narratives and performed semantic, episodic, and working memory tasks. AD patients produced less connected narratives than cognitively healthy older adults. Connectedness was associated with semantic memory in AD and with episodic memory in controls. Word-graphs connectedness represents a practical tool to assess cognitive impairment in AD patients.
Segmented Linear Mixed Model Analysis Reveals Association of the APOE ɛ4 Allele with Faster Rate of Alzheimer’s Disease Dementia Progression
Authors: Chen X. Richard ,   for the Alzheimer’s Disease Neuroimaging Initiative, Shao Yongzhao , Sadowski Martin J.
Published: June 2021

Background: APOE ɛ4 allele carriers present with an increased risk for late-onset Alzheimer’s disease (AD), show cognitive symptoms at an earlier age, and are more likely to transition from mild cognitive impairment (MCI) to dementia but despite this, it remains unclear whether or not the ɛ4 allele controls the rate of disease progression. Objective: To determine the effects of the ɛ4 allele on rates of cognitive decline and brain atrophy during MCI and dementia stages of AD. Methods: A segmented linear mixed model was chosen for longitudinal modeling of cognitive and brain volumetric data of 73 ɛ3/ɛ3, 99 ɛ3/ɛ4, and 39 ɛ4/ɛ4 Alzheimer’s Disease Neuroimaging Initiative participants who transitioned during the study from MCI to AD dementia. Results: ɛ4 carriers showed faster decline on MMSE, ADAS-11, CDR-SB, and MoCA scales, with the last two measures showing significant ɛ4 allele-dose effects after dementia transition but not during MCI. The ɛ4 effect was more prevalent in younger participants and in females. ɛ4 carriers also demonstrated faster rates of atrophy of the whole brain, the hippocampus, the entorhinal cortex, the middle temporal gyrus, and expansion of the ventricles after transitioning to dementia but not during MCI. Conclusion: Possession of the ɛ4 allele is associated with a faster progression of dementia due to AD. Our observations support the notion that APOE genotype not only controls AD risk but also differentially regulates mechanisms of neurodegeneration underlying disease advancement. Furthermore, our findings carry significance for AD clinical trial design.

Published: June 2021

Robotic surgery offers surgeons a greater degree of accuracy, versatility, and control than with standard techniques for other kinds of complicated procedures. The robotic surgery technology offers numerous advantages for patients and leads to unforeseen effects that are easier to predict when such a complex interactive device is used for treatment. The challenging complications that are occurred during robotic surgery include, risk of human error while operating the robotic system and the possibility for mechanical failure. The paper proposes Robot Assisted - Remote Center Surgical System (RA-RCSS) to improve mechanical malfunction threat and practical skills of surgeons through intra practice feedback and demonstration from human experts. A mask region-based supervised learning model is trained to conduct semantic segmentation of surgical instruments and targets to improve surgical coordinates further and to facilitate self-oriented practice. Furthermore, the master-slave bilateral technique is integrated with RA-RCSS to analyze the mechanical failures and malfunctions of the robotic system. The emerging safety standard environment is presented as a key enabling factor in the commercialization of autonomous surgical robots. The simulation analysis is performed based on accuracy, security, performance, and cost factor proves the reliability of the proposed framework.
Hybridized Fourier transform infrared spectroscopy for early prediction of smoldering fire in cotton
Authors: Yao Peng
Published: June 2021

Cotton is the most commonly used natural textile fiber for humans, and fire protection is essential during transport, storage, and production. However, certain fabrics have a comparatively high-temperature emission and adsorb moisture from the air, leading to cotton smoldering in the textile industry. Hence, in this paper, Hybridized Fourier transform infrared spectroscopy (HFTIS) method has been proposed to identify the fire behavior and thermal degradation products. Firstly, the fibers spectra have been obtained, and then spectral information is established to define and classify the connection between the vibrations of characteristic chemical groups and the corresponding wavelengths. The HFTIS method aims to progress the gas analysis of smoke gases and a reliable approach for the toxic component determination in combustion gases related to fire test situations. The simulation analysis of the measurements specified that HFTIS provides a performance ratio of 95.4%, prediction ratio of 96.1%, reliability 96.6%, accuracy ratio of 97.8%, and smoldering spread rate of 15.5% compared to other existing methods.

Authors: Zhang Lige , Tian Zhen
Published: June 2021

Aerobics is full of charm, and music plays an inestimable role in it. With the penetration of music in aerobics, the “sound” of music art is introduced into the “shape” of aerobics movements, and the visual art and visual experience are perfectly combined, which greatly expands the extension and extension of aerobics. This paper proposes an aerobics music adaptation recommendation algorithm that combines classification and collaborative filtering. First, by calculating the similarity of the user context information, the collaborative filtering algorithm obtains the initial annihilation grass music recommendation list; then the classification model is trained by the machine learning algorithm to obtain the user’s aerobics music type preference in a specific context; finally, collaborative filtering The obtained recommendation list is integrated with the aerobics music preference obtained by the classification model to provide personalized aerobics music adaptation recommendations for users in specific situations. In the specific aerobics music adaptation recommendation, the algorithm is implemented by a deep neural network composed of an independent cyclic neural network algorithm and an attention mechanism. In the data preprocessing stage, the audio of the user’s listening history is preprocessed by scattering transformation. The audio features of the user’s listening history are extracted by scattering transformation, and then this feature is combined with the user’s portrait to obtain a recommendation list through an independent recurrent neural network with a hybrid attention mechanism. The experimental results show that this method can effectively improve the performance of the personalized music recommendation system. Compared with the traditional single algorithm IndRNN and LSTM, the recommendation accuracy is improved by 7.8% and 20.9%, respectively.
A study on the evolution of port logistics network based on complex theory: A case study of key coastal ports in China
Authors: Xu Xu , Yang Yanbing , Liu Yi
Published: June 2021

Based on the complex network theory, we construct a weighted network evolution model with limited point weight considering node attractiveness and shipping distance. After this the evolution simulation is carried out based on the data of 18 coastal ports mentioned in the Belt and Road Initiative, and the validity of the model is verified by comparing the net-work eigenvalues between evolving network and real network. The results show that the shipping network has the characteristics of small world and scale-free network, and the evolutionary network has shorter average path, stronger agglomeration, greater degree difference, and more frequent and efficient network connection. Based on the evolving network, the position of Lianyungang as a hub needs to be strengthened. For ports with small network values, such as Shantou, Qin-zhou and Sanya, it is necessary to expand trade between ports. Finally, we also provide strategies for improving China’s key coastal port networks from the perspective of port enterprises, shipping enterprises and government.

Authors: McKinney Ellen , Morris Kristen , Wu Yingying , Griffin Linsey , Sokolowski Susan , Carufel Robin , Park Juyeon
Published: June 2021

BACKGROUND: Inadequately fitting turnout coats and pants hamper mobility and safety of firewomen. Previous research has established that firewomen are dissatisfied with their turnout coats and pants. Yet, there has been minimal in-depth research into the specific fit problems and consequences of these problems on the workplace health of firewomen. OBJECTIVE: The researchers sought to uncover common fit problems firewomen have with turnout coats and pants, and their impact on mobility and safety while performing work. METHODS: The researchers performed a qualitative analysis of in-depth interviews of 35 firewomen. RESULTS: The study illuminated specific fit problems firewomen have with their turnout coats and pants. These fit challenges include challenges with the overall proportions of the turnout coats and pants as well as issues of length and how the turnout coats and pants fit around their body (circumference), leading to concerns about mobility and safety. CONCLUSIONS: This study builds an understanding of specific fit problems on the ability of firewomen to do their challenging work in a safe and stress-free manner. Firewomen’s protective apparel should protect and empower all firewomen. To adequately protect firewomen, manufactures should prioritize the implementation of these findings to improve the safety and mobility that firewomen’s turnout coats and pants offer them.

Authors: Mongeau S. , Lightfoot N. , MacEwan L. , Eger T.
Published: June 2021

BACKGROUND: Workers who suffered a workplace injury and submitted a claim with the compensation board in Ontario often faced economic and non-economic costs that provoked depressive feelings, family strain, financial strain, and feelings of diminished self-worth. OBJECTIVE: This qualitative descriptive study aimed to understand the perceived gaps and failures associated with the support systems (e.g., union, compensation and employer) that were in place to assist some male underground workers in Sudbury, Ontario, Canada, who had suffered a workplace injury and had a compensation claim. METHODS: Twelve in-depth, in-person, individual, semi-structured interviews were conducted and data were transcribed verbatim and anonymized at the time of transcription. Data analysis followed Braun and Clarke’s guidelines for thematic analysis. RESULTS: Themes that emerged include: unfair and inadequate recognition of an injury; limited communication with stakeholders involved with their claim, including claim adjudicators, challenges when returning to work, and compensation claim system barriers. CONCLUSIONS: Cooperation, collaboration, knowledge transfer, and decreased power imbalances could help to reduce the economic and non-economic strain felt by a worker with an injury. Additionally, a government-funded third-party advocate who knows the medical system, union contracts, the workers’ compensation system, and employer policies and practices could act on behalf of an injured worker.
Correlation of exercise style to mental health and social adaptability of college students
Authors: Chen Yu , Sto Chloe
Published: June 2021

BACKGROUND: Talents are the basis of all development and comprehensive strength of a country. As college students who are about to contact the society, their mental health and social adaptability are the most critical factors for their entry into society. OBJECTIVE: Therefore, this study explores the correlation of exercise style to mental health and social adaptability of college students. METHODS: Based on the sample processing of college students in 4 universities in a city, 1,000 students are selected for research on the correlation of exercise style to mental health and social adaptability. In addition, the impacts of college students participating in sports activities on their mental health and social adaptability are analyzed. RESULTS: When the duration of a single sports activity is 30–60 min, the mental health of students reaches optimal. On the contrary, when the duration of a single sports activity exceeds 90 min, the mental health of students is low. This indicates that the more students participate in sports activities, the stronger the social adaptability is. When the intensity of sports activities for students is moderate, the average scores of interpersonal communication ability of students are the highest. When the duration of a single sports activity is 60–90 min, the average scores of living adaptability of students are the highest. If students keep the appropriate duration and intensity of sports activities, their social adaptability will be improved notably. CONCLUSION: The social adaptability of students is related to the number of times they participate in sports activities, the duration of a single sports activity, and the intensity of sports activities. However, while exercising, students should plan the duration of sports activities to avoid excessively prolonged exercise time. In addition, students should beware their exercise intensity of sports activities. The optimal choice of exercise intensity is moderate or slightly tired.
Effect of mental resilience of left-behind children on self-esteem and emotional processing bias and social coping styles
Authors: Ma Yaju
Published: June 2021

BACKGROUND: The long-term separation of parents and children as well as the incomplete family structure affect the mental health development of left-behind children and the formation of healthy personality, good interpersonal relationships and positive coping styles in adulthood. At present, there is insufficient empirical investigations on the mental resilience of left-behind children. OBJECTIVE: It is aimed to understand the mental health of left-behind children and explore the characteristics of mental resilience, self-esteem and emotional processing bias, as well as social coping styles. METHODS: The random sampling method is used to select the left-behind children as the research subject. The general demographic information questionnaire, RSCA (Resilience Scale for Chinese Adolescent), emotional self-rating scale, SES (Self-Esteem Scale), and coping style questionnaire are used for the survey. Also, the experiments on cognitive processing bias effects of self-esteem and emotion are further carried out. RESULTS: There are differences in demographic variables in mental resilience, self-esteem level, emotional level, and social coping styles. The low mental resilience group shows a processing bias towards low praise words, while the high mental resilience group shows a processing bias towards high praise words. At a low level of self-esteem, there is an interaction between mental resilience and self-esteem on low praise words. Mental resilience has a significant effect on the cognitive processing bias of emotion. Under the induction of positive emotions, the high mental resilience group responds significantly more slowly to the negative words than the low mental resilience group. Under the induction of negative emotions, the high mental resilience group responds significantly faster to the negative words than the low mental resilience group. CONCLUSIONS: Promoting the mental health education of left-behind children can start from enhancing positive emotions, reducing negative emotions, developing high self-esteem, and improving mature coping styles.

Authors: Lu Jingfu , Yu Yanliang , Zhao Yang , Jenkin Michelle
Published: June 2021

BACKGROUND: Under the background of the information society, teachers’ pressure from work and life is increasing. Meanwhile, the working pressure has a potential inevitable connection with the physical and mental health of teachers. OBJECTIVE: To analyze the correlation between working pressure of workers and mental health status, expand the application of the job demand-resource stress (JD-RS) model in the adjustment of working characteristic pressure, and achieve the coordinated development between working pressure and mental health. METHODS: The occupation of the teacher is taken as the research object. First, the pressure source questionnaire and Symptom Check List 90 (SCL-90) are chosen to measure the working pressure and mental health. Also, the reliability and validity of the pressure source questionnaire are tested. Second, the gender, duty, teaching age, and workload of teachers are chosen as the foundation for comparing and analyzing the impact of various dimensions and project factors on teachers’ working pressure and mental health. Finally, based on the method of univariate linear regression analysis, the correlation between teachers’ working pressure and mental health is analyzed and characterized. RESULTS: The measurement tool based on the pressure source questionnaire has good performance reliability and validity. The five dimensions of Cronbach’s coefficients are all greater than 0.8, and the indicators of fitting all meet psychometrics requirements. Significance analysis shows that different genders, duties, teaching ages, and workloads have different levels of significant influence on teachers’ working pressure and mental health. Linear regression analysis shows that teachers’ working pressure has a significant impact on their physical and mental health, which has a predictive effect. Teachers who bear high-intensity pressure have psychological problems. CONCLUSIONS: The research based on the JD-RS model has a positive role in promoting the balanced and coordinated development of working pressure and the physical and mental health of employed workers.

Published: June 2021

BACKGROUND: College students are a high-risk subpopulation of psychological disorders. The problem of various adverse phenomena and consequences caused by excessive pressure on college students has gradually become the focus of social and psychological academic circles. However, studies related to individual self-concept and psychological pressure are rare. OBJECTIVE: To explore the impact of sports dance exercises on college students’ psychological pressure and improve the psychological effects of their self-satisfaction. METHODS: College students were taken as research objects, randomly divided into a control group and an observation group. The observation group is intervened with sports dance exercises. The observation group was intervened with sports dance exercises. The stress response characteristic questionnaire and multidimensional self-satisfaction rating scale were utilized to measure college students’ conditions before and after the intervention. Finally, the obtained data were statistically analyzed. RESULTS: Generally, the psychological stress response of college students was mild, with self-satisfaction and various dimensions at a moderately higher level. No significant differences were discovered in the psychological stress response and self-satisfaction level between the control group and the observation group before intervention (P > 0.05), which were homogeneous. Compared with the data obtained before the intervention, after the intervention, the control group scores were slightly reduced in all dimensions of the psychological stress response and self-satisfaction. In contrast, the scores were significantly increased in the experimental group (P < 0.05). Psychological stress response could reliably explain 30.4%of the total self-satisfaction variance (P < 0.01). The negative self-evaluation was the most important variable affecting self-satisfaction, followed by poor interpersonal communication and poor sleeping quality. CONCLUSIONS: Sports dance exercises could alleviate the psychological stress of college students and improve their self-satisfaction. Colleges and universities should include sports dance in the content of optional public courses and encourage more college students to actively participate in sports dance exercises to improve their mental health.

BACKGROUND: the relationship between physical exercise (PE) and mental health (MH) had been an important research topic in exercise psychology. With the development of society, the increasingly fierce social competition had put forward higher and higher requirements for college students’ social adaptability (SA). As members of the new era, college students were expected to not only have innovative knowledge concept, solid knowledge foundation, and healthy psychology, but also have the ability to adapt to the changes in the environment, know how to get along with others, and deal with problems alone. OBJECTIVE: this study aimed to evaluate the PE, MH, and SA of college students, and to analyze the internal relationships among PE, MH, and SA. METHODS: based on questionnaire survey, college students were randomly selected for investigation and the data were statistically processed. RESULTS: there were significant differences in the MH of students of different genders, majors, grades, and origins. There was a significant difference between the amount of exercise and the MH of college students. The amount of exercise was positively correlated with the MH level of college students, and there was also a positive correlation between PE and MH. The SA of the physical exercisers was average, but the SA of the non-physical exercisers was poor. There was a significant difference between the SA of the physical exercisers and the non-physical exercisers. There were significant differences in the SA between physical exercisers and non-physical exercisers of different genders, majors, grades, and origins. Physical exercisers who participated in team sports were more socially adaptable. There was no significant difference in the SA of physical exercisers of different genders, majors, and origins, and the SA of senior students was stronger. CONCLUSIONS: PE had a positive effect on college students’ MH and social adaptation ability. Colleges and universities could improve their MH and social adaptation ability by arranging appropriate PE.
A Comparative Legal and Historical Study of the Commons in Italy and England and Wales
Authors: Pieraccini Margherita
Published: June 2021

- Margherita Pieraccini Historically, common land occupied a central role in the agrarian and cultural economies of Europe. Although the governance of the commons shaped by different regimes of property rights was heterogeneous, it is possible to uncover a common ground in the widespread centrality assigned to customs. Today, common land is not an anachronistic relict but remains an interesting area of study given its revitalisation in national policies and laws. This article presents a study of comparative law between English and Welsh common land and Italian commons, focussing on the similar historical transformation they experienced. In fact, the predominance of agrarian practices and local customs of the past has been erased by the nationalisation of the commons in both countries. In Italy, this nationalisation should be attributed to the levelling philosophy of the 1766/1927 law, in England and Wales to the Commons Registration Act 1965 and Commons Act 2006. If contemporary political and legislative discourses portray the commons as examples of environmental sustainability and communitarian governance, in reality this position is more a product of a political adhesion to the recent discursive orthodoxy centred on the community than a genuine legislative attempt to confer responsibility and autonomy to the principal stakeholders of the commons. From a theoretical point of view the article follows the institutionalist approach, nonetheless criticising its holistic understanding of the concepts of community and locality. Key words: common land, governance, customs, sustainability, England and Wales, Italy.
I cinquant'anni della Pac e il suo futuro
Authors: Bianchi Daniele
Published: June 2021

- It has been qualified as a quiet or silent revolution, a revolution that European farmers have lived from the post-war period, the revolution that the CAP has brought into the agriculture world at European and International level. Since then, the role of agriculture in national economies has changed substantially and with it the very foundations of agriculture and agricultural policy. Since the end of 2007, how many front pages were devoted to agriculture? The significant increase in prices of agri-food products, the food versus fuel, the use of biotechnology, food fraud, speculation all these issues refocus attention on agriculture. But regardless of the breaking news, this is also the sign of the new role that agriculture plays since a long time. The farmer no longer produces food. The job of a farmer has become more complex. After having quickly recalled the evolution and achievements of fifty years of agricultural policy, attention will be particularly dedicated to the health check of PAC done in 2008, in the context (rectius different contexts) in which CAP will be called to operate in view of 2013 - end of the budget period - and, mainly, in view of the post 2013. After having analysed the procedural innovations that the Lisbon Treaty introduces into the 2003 CAP reform, we will tackle the long-lasting issue of CAP funding in the persistent global economic crisis and in a context of multilateral negotiations stalling. And in particular, we will wonder how the current single payment scheme in close cooperation with the second pillar (rural development) and with the flexibility tools introduced in the health check can provide an answer to the perennial question of justification for Community support to farmers.
