Combination of Bonding, Bridging and Linking Social Capital in a Livelihood System: Nomadic Duck Herders Amid the Covid-19 Pandemic in South Sulawesi, Indonesia
Authors: Salman Darmawan , Kasim Kasmiyati , Ahmad Asmita , Sirimorok Nurhady
Published: March 2021

Livelihood systems of nomadic duck herders make a unique study subject due to the livelihood assets, strategies, and outcomes they manage, which involve interactions with various actors that keep moving around. Social capital the duck herders build in their interaction with other actors, namely rice farmers, play an important role to face different vulnerability context, including those brought by the Covid-19 pandemic. This study aims to characterize components of bonding, bridging and linking social capital in the context of relationships between duck herders and other actors, and seeks to find the essential role of the combination of the three types of social capital for livelihood outcomes, particularly in facing vulnerabilities due to the pandemic. The method of grounded theory research was applied for its ability to allow researchers to reveal processual relationships between duck herders and other actors. Data were collected through semi structured interviews, analyzed by open, axial, and selective coding. The duck herders combine components of bonding, bridging, and linking social capital selectively depending on the interests behind each interaction with different actors. The bridging and linking role that social capital plays in herders’ interactions with farmers and irrigation officials is undertaken in order to gain access to natural capital (rice fields and irrigated water), while in their interaction with egg traders, they utilize bridging social capital to gain access to financial capital (in the form of cash and loans). The vulnerability context due to the pandemic has shaken the livelihood system of the duck herders by upsetting the egg supply chain due to social restriction policies. Social capital therefore plays an important role in facing vulnerability, in the context of forming good will among egg traders that continued to buy eggs from the duck herders, which served as a kind of pay back for the loyalty of the duck herders. We find that social capital plays a vital role in a livelihood system, within which the access to livelihood assets depend on social relations. This study also explored the impact of the Covid-19 pandemic as it resonates more on supply chains than production processes.
Análisis patémico de El miedo a los animales, de Enrique Serna
Authors:   , Amador García Ricardo
Published: March 2021

La presente investigación pretende explicar y aplicar la semiótica patémica, propuesta de Greimas y Fontanille, teoría que puede aportar elementos para el análisis del lenguaje y las pasiones. La semiótica se aplicará al discurso literario, en específico al género negro mexicano, para mostrar el peso de las acciones de los personajes y sus implicaciones en la trama. De lo que se trata es de ver como se configuran discursivamente, a través del acto narrativo, las pasiones. Me propongo, como objetivo general, indagar la escalada emocional de los personajes en el discurso literario desde la óptica de la semiótica de las pasiones. Para tal propósito se tomó como muestra el género negro mexicano por sus características: la emotividad de los personajes, en especial del detective o investigador, las motivaciones de los delincuentes y la crítica permanente al poder.
El discurso epigramático en La zorra enferma de Eduardo Lizalde y el empoderamiento contra los sistemas político, religioso, amoroso y literario
Authors:   , Carmona Flores Joanna
Published: March 2021

Después del exhaustivo análisis de la obra a trabajar, y de varios replanteamientos de la hipótesis, la propuesta de esta investigación es que La zorra enferma es un libro en el que se evidencian los excesos del poder y el doble discurso que encubre las formas siniestras para perpetuar el poder; por ello, el discurso epigramático es útil para criticar los excesos de cualquier sistema. Considerando lo anterior, la hipótesis es El discurso epigramático en La zorra enferma de Eduardo Lizalde es la estrategia de crítica y empoderamiento contra los sistemas político, religioso, amoroso y literario. Lo escrito en las páginas siguientes de la investigación asegura que lo epigramático es un recurso ideal para criticar al poder y su deber ser en cualquier sistema. Así, la capacidad crítica y la inconformidad son valores importantes del libro.

Aims

Pulmonary vein isolation (PVI) using cryoballoon ablation (CBA) is mainly reserved for patients with drug-refractory or drug-intolerant symptomatic atrial fibrillation. We evaluated a large cohort of patients treated in a real-world setting and examined the safety and efficacy profile of CBA when applied as a first-line treatment for atrial fibrillation.

Methods

In total, 249 patients (23% women; 56 ± 13 years; mean left atrial diameter 41 ± 7 mm; 73.5% paroxysmal atrial fibrillation; and 26.5% persistent atrial fibrillation) underwent an index PVI by CBA. Data were collected prospectively in the framework of the 1STOP ClinicalService project, involving 26 Italian cardiology centers.

Results

Median procedure and fluoroscopy times were 90.0 and 21.0 min, respectively. Acute procedural success was 99.8%. Acute/periprocedural complications were observed in seven patients (2.8%), including: four transient diaphragmatic paralyses, one pericardial effusion (not requiring any intervention), one transient ischemic attack, and one minor vascular complication. The Kaplan--Meier freedom from atrial fibrillation recurrence was 86.3% at 12 months and 76% at 24 months. Seventeen patients (6.8%) had a repeat catheter ablation procedure during the follow-up period. At last follow-up, 10% of patients were on an anticoagulation therapy, whereas 6.8% were on an antiarrhythmic drug.

Conclusion

In our multicenter real-world experience, PVI by CBA in a first-line atrial fibrillation patient population was well tolerated, effective, and promising. CBA with a PVI strategy can be used to treat patients with paroxysmal and persistent atrial fibrillation with good acute procedural success, short procedure times, and acceptable safety.

From "knowing" to "not knowing": Critical global citizenship education for engineering partnerships
Authors: Reynolds Nora Pillard
Published: March 2021

This article was part of a larger study that explored community participants’ perspectives in [Municipality, Country] about the long-term global service learning (GSL) partnership with [Name of university] University’s College of Engineering (Author, year). This article explores the question: From the community participants’ perspectives, what are their educational goals for the university engineering students in this partnership? While I intentionally centered this article on the community participants’ perspectives, I also explored areas of alignment and areas of difference between the different stakeholder groups’ perspectives about learning and knowledge. Although global citizenship surfaced in interviews with both community and university participants, the community participant perspectives push farther than the university administrators/ faculty and call for critical global citizenship education (Andreotti, 2006).

INVENTORY OF SNAKES: COMPARATIVE ANALYSIS AROUND PARANÁ RIVER BETWEEN THE NORTHWEST OF THE STATE OF SÃO PAULO AND EAST OF THE STATE OF MATO GROSSO DO SUL

 

ABSTRACT

This paper aims to inventory snakes species found in the border of both São Paulo and Mato Grosso do Sul States, around Paraná River, having as reference the municipalities of Santa Fé do Sul (SP) and Aparecida do Taboado (MS), including bordering municipalities. Data about snake’s incidence in that region was collected with the help of the community, Fire Brigade and Health Secretary. At first, it was reported, a total of 11 genres, 12 species, and 34 specimens of snakes distributed in four families (Boidae, Elapidae, Viperidae and Dipsadidae). In São Paulo northeast 10 species were found, 3 of them were only found in São Paulo, whereas in Mato Grosso do Sul, 19 species, 2 of them were found in Mato Grosso do Sul. All the other species were found in both States. It was recorded that the incidence of Boa constrictor is notoriously higher than the incidence of other species, being 60% higher than the second one for Erytrolamprus Poecilogyrus. It is a comparative analysis, thus there is not a big difference in the total number of species for both States. Regarding health issues, the data presented a higher quantity of ophidian accidents in the city of Paranaíba in the State of Mato Grosso do Sul.

El presente artículo tiene el objetivo de estudiar el apoyo familiar a la población femenina en el medio abierto del Sistema Penitenciario Español como uno de los factores relacionados con su proceso de reinserción y tránsito a la libertad, analizando las fuentes, el grado y tipología de apoyos familiares para la vuelta a la vida en libertad. Este trabajo se enmarca dentro del proyecto de investigación I+D+I “Procesos de reinserción y acompañamiento a mujeres en semilibertad”(ref. EDU2016-79322-R) cuya metodología ha empleado métodos cualitativos y cuantitativos, de forma complementaria, aplicados a los 310 cuestionarios mixtos y a las 67 entrevistas semiestructuradas, diseñados ad hoc, en 31 centros penitenciarios que representan los distintos recursos de cumplimiento de condena en medio abierto. Se ha hecho un análisis descriptivo de los resultados y comparado la tendencia de los apoyos en el momento anterior a prisión y en el actual mediante la realización del test de McNemar por cada figura familiar estudiada. Los resultados obtenidos evidencian que el abandono o pérdida de apoyos es relativamente bajo, oscilando entre un 3,2% y 8,1% de las participantes según los diferentes miembros de la familia; manteniendo casi un tercio de ellas los apoyos de muchas de las personas de sus familias; e incluso consiguiendo apoyos nuevos como es en el caso de un 10,6% de las participantes al hablar de sus parejas.

En este trabajo se presentan los resultados obtenidos en una investigación realizada en 31 entidades penitenciarias españolas y, tiene por objeto analizar el acceso de las mujeres penadas a los distintos niveles educativos, especialmente en los estudios medios o superiores, y su relación con distintos factores de riesgo y protección intervinientes. La muestra global (310 mujeres, 30,1%) se ha seleccionado utilizando muestreo bietápico, de la población de mujeres en cumplimiento de condena en medio abierto. La metodología que se ha usado combina métodos cuantitativos y cualitativos, aplicados a los instrumentos desarrollados diseñados ad hoc (cuestionario de mujeres y entrevistas personales, y cuestionario de profesionales). Los resultados muestran que la mayor parte abandonan los estudios en las enseñanzas básicas, observándose distintos factores de riesgo; sin embargo, las pocas que continúan o retoman los estudios medios o superiores en prisión, lo consideran como un factor de protección frente al ambiente penitenciario, permitiéndoles gestionar de forma inteligente y saludable el tiempo en contextos penitenciarios, mejorando las relaciones entre las presas, con las familias y los trabajadores de prisión. También consideran que les puede resultar útil para el futuro, especialmente, en el ámbito laboral.What do you want to do ?New mailCopy What do you want to do ?New mailCopy What do you want to do ?New mailCopy What do you want to do ?New mailCopy
Exploring the in-silico approach for assessing the potential of natural compounds as a SARS-CoV-2 main protease inhibitors
Authors: Patel Ashish , Patel Alkesh , Hemani Rahul , Solanki Riddhi , Kansara Janki , Patel Gargi , Pradhan Sayantan , Bambharoliya Tushar
Published: March 2021

The SARS-CoV-2 virus emerged as a major cause of the COVID-19 pandemic in December 2019. Many attempts have been made to block the viral infection by targeting various processes like its entry, uncoating, replication, activating T cells response, and rising antibody titer. Also, many drugs are repurposed like remdesivir, dexamethasone, tocilizumab, hydroxychloroquine based on their established therapeutic efficacy against other viruses in the past. Natural products (NP) consist of a promising candidate and are needed to evaluate those molecules with molecular docking for preliminary screening and in vitro studies. Therefore, in the present study, a total of 12 active constituents from natural products like Ashwagandha, Tinospora cordifolia, Tea, Neem and lemon balm were docked, using the Autodock tool, onto the crystal structure of SARS CoV-2 main protease (PDB ID-5R80), to study their capability to act as main protease (Mpro) COVID-19 inhibitors. All NPs derivatives displayed good binding energies (ΔG) ranging from -8.8 to -5.2 kcal/mol, but berberine, epicatechin, and rosmarinic acid were found most potent, among others. Therefore, good binding energy, drug-likeness, and efficient pharmacokinetics suggest the potential of NPs derivatives as SARS-CoV-2 main protease (Mpro) inhibitors. However, further research is necessary to investigate the ability of these compounds as COVID-19 inhibitors.
Hydrogen Storage by Reduction of CO₂ to Synthetic Hydrocarbons
Authors: Zhao Kun , Luo Wen , Gallandat Noris , Zhang Jie , Züttel Andreas
Published: March 2021

The storage of renewable energy is crucial for the substitution of fossil fuels with renewable energy. Hydrogen is the first step in the conversion of electricity from renewable sources to an energy carrier. However, hydrogen is technically and economically challenging to store, but can be converted with CO2 from the atmosphere or oceans to hydrocarbons. The heterogeneously catalyzed gas phase reaction and the electrochemical CO2 reduction are reviewed and the application of a new type of reactor is described. The mechanism of the gas phase CO2 reduction on a heterogeneous catalyst is shown in detail and the function of the supported catalyst is explained. Finally, an economic estimation on the cost of synthetic methane is presented which leads to a cost of 0.3 CHF/kWh in CH4.
Benchmarking London dispersion corrected density functional theory for noncovalent ion-pi interactions
Authors: Spicher Sebastian , Caldeweyher Eike , Hansen Andreas , Grimme Stefan
Published: March 2021

The strongly attractive noncovalent interactions of charged atoms or molecules with p-systems are important binding motifs in many chemical and biological systems. These so-called ion-pi interactions play a major role in enzymes, molecular recognition, and for the structure of proteins. In this work, a molecular test set termed IONPI19 is compiled for inter- and intramolecular ion-pi interactions, which is well balanced between anionic and cationic systems. The IONPI19 set includes interaction energies of significantly larger molecules (up to 133 atoms) than in other ion-pi test sets and covers a broad range of binding motifs. Accurate (local) coupled cluster values are provided as reference. Overall, 18 density functional approximations, including seven (meta-)GGAs, seven hybrid functionals, and four double hybrid functionals combined with three different London dispersion corrections, are benchmarked for interaction energies. DFT results are further compared to wave function based methods such as MP2 and dispersion corrected Hartree-Fock. Also the performanceof semiempirical QM methods such as the GFNn-xTB and PMx family of methods is tested. It is shown that dispersion-uncorrected DFT underestimates ion-pi interactions significantly, even though electrostatic interactions dominate the overall binding. Accordingly, the new charge dependent D4 dispersion model is found to be consistently better than the standard D3 correction. Furthermore, the functional performance trend along Jacob’s ladder is generally obeyed and the reduction of the self-interaction error leads to an improvement of (double) hybrid functionals over (meta-)GGAs, even though the effect of the SIE is smaller than expected. Overall, the double hybrids PWPB95-D4/QZ and revDSD-PBEP86-D4/QZ turned out to be the most reliable among all assessed methods in predicting ion-pi interactions, which opens up new perspectives for systems where coupled cluster calculations are no longer computationally feasible.
One-Pot Synthesis of High-Capacity Silicon-Lithium Anodes via On-Copper Growth of a Semi-Conducting, Porous Polymer

Published: March 2021

Silicon-based anodes with lithium ions as charge carriers have the highest predicted charge density of 3579 mA h g-1 (for Li15Si4) while being comparatively safe. Contemporary electrodes do not achieve these theoretical values largely because production paradigms remained unchanged since their inception and rely on the mixing of weakly coordinated, multiple components. In this paper, we present the one-pot synthesis of high-performance anodes that reach the theoretical capacity of the fully lithiated state of silicon. Here, a semi-conductive triazine-based graphdiyne polymer network is grown around silicon nanoparticles directly on the current collector, a copper sheet. The current collector (Cu) acts as the catalyst for the formation of a semi-conductive triazine-based graphdiyne polymer network that grows around the inorganic, active material (Si). In comparison to established electrode assemblies, this process (i) omits any steps related to curing, drying, and annealing, (ii) does away with binders and conductivity-enhancing additives that decrease volumetric and gravimetric capacity, and (iii) cancels out the detrimental effects on performance, chemical and physical stability of conventional, three-component anodes (Si, binder, carbon black). This is because, the porous, semi-conducting organic framework (i) adheres to the current collector on which it grows via cooperative van der Waals interactions, (ii) acts effectively as conductor for electrical charges and binder of silicon nanoparticles via conjugated, covalent bonds, and (iii) enables selective transport of mass and charge-carriers (electrolyte and Li-ions) through pores of defined size. As a result, the anode shows extraordinarily high capacity at the theoretical limit of fully lithiated silicon, excellent performances in terms of cycling (exceeding 70% capacity retention after 100 cycles), and high mechanical and thermal stability. These high-performance anodes pave the way for use in flexible, wearable electronics and in environmentally demanding applications.

Healthcare workers’ knowledge, attitudes and behaviours with respect to antibiotics, antibiotic use and antibiotic resistance across 30 EU/EEA countries in 2019
Authors: Ashiru-Oredope Diane , Hopkins Susan , Vasandani Sagar , Umoh Eno , Oloyede Olaolu , Nilsson Andrea , Kinsman John , Elsert Linda , Monnet Dominique L ,   the #ECDCAntibioticSurvey Project Advisory Group
Published: March 2021

Background

While several studies have assessed knowledge, attitudes and behaviours of the public, physicians and medical students in a number of EU/EEA countries with respect to antibiotic use and antibiotic resistance, there is a paucity of literature for other healthcare workers. This survey aimed to fill this gap.

Methods

A 43-item online questionnaire was developed, validated and pilot-tested through a modified Delphi consensus process involving 87 Project Advisory Group (PAG) members, including national representatives and members of European health professional groups. The survey was distributed by the PAG and via social media to healthcare workers in 30 EU/EEA countries.

Results

Respondents (n = 18,365) from 30 EU/EEA countries participated. Knowledge of antibiotics and antibiotic use was higher (97%) than knowledge of development and spread of antibiotic resistance (75%). Sixty percent of respondents stated they had received information on avoiding unnecessary prescribing, administering or dispensing of antibiotics. Among respondents who prescribed, administered or dispensed antibiotics, 55% had provided advice on prudent antibiotic use or management of infections to patients, but only 17% had given resources (leaflets or pamphlets). For community and hospital prescribers, fear of patient deterioration or complications was the most frequent reason (43%) for prescribing antibiotics that were considered unnecessary. Community prescribers were almost twice as likely as hospital prescribers to prescribe antibiotics due to time constraints or to maintain patient relationships.

Conclusion

It is important to move from raising awareness about prudent antibiotic use and antibiotic resistance among healthcare workers to designing antimicrobial stewardship interventions aimed at changing relevant behaviours.

Published: March 2021

In March 2019, a pertussis outbreak occurred in children in a junior school (7–11 years) in England who had been offered pertussis-containing booster vaccine at 40 months of age. In a case–control investigation, we assessed the extent of transmission and any difference in protection afforded to those who had previously received a booster 3- or 5-component acellular pertussis vaccine (aP). We took oral fluid specimens from the students to determine IgG antibodies against pertussis toxin (anti-PT). Parents of students attending the school were sent a questionnaire on pertussis symptoms and vaccination status was retrieved from general practitioner records for all students. Of 381 students, 134 (35.2%) were classified as pertussis cases, 133 by demonstration of significant anti-PT IgG titres and one clinically. There was no significant difference in the risk of pertussis between students receiving 3-component (33.7%) or 5-component (32.3%) aP boosters. However, pertussis infection differed significantly in school year 4, with 22.9%, 50.0%, 23.7% and 38.1% pertussis cases in years 3, 4, 5 and 6, respectively. The proportion of students with incomplete vaccinations recorded was higher than the proportion of those not covered according to the national reported coverage, possibly contributing to sustained transmission within the school.

The emergence of SARS-CoV-2 P.1 lineage coincided with a surge in hospitalisations in the North region of Brazil. In the South region’s Rio Grande do Sul state, severe COVID-19 case numbers rose 3.8 fold in February 2021. During that month, at a COVID-19 referral hospital in this state, whole-genome sequencing of a subset of cases’ specimens (n = 27) revealed P.1 lineage SARS-CoV-2 in most (n = 24).

Sera were collected from 185 adults aged ≥ 70 years in London to evaluate the immune response to COVID-19 vaccines. A single dose of Pfizer/BioNtech vaccine resulted in > 94% seropositivity after 3 weeks in naïve individuals using the Roche Spike antibody assay, while two doses produced very high spike antibody levels, significantly higher than convalescent sera from mild-to-moderate PCR-confirmed adult cases. Our findings support the United Kingdom’s approach of prioritising the first dose and delaying the second dose of COVID-19 vaccine.
Assessment and Development of Path Loss Propagation Model for Ikire Metropolis, Nigeria
Authors: POPOOLA Jide
Published: March 2021

The aim of this paper is to assess and develop path loss propagation model for terrestial radio broadcasting station in Ikire, Nigeria. In carrying out the study, the reception quality of Osun State Corporation (OSBC) broadcast signal strength within Ikire metropolis in Irewole Local Government Area of Osun State, Nigeria was assessed using BC1173 Field Strength meter. The data obtained from the signal strength measurements around the metropolis were subsequently analysed and used for the development of an ideal propagation path loss model for the metropolis. The developed path loss model for the metropolis was evaluated and found to outperform the COST-231 Hata model in literature. The comparative performance evaluation result of the developed model and the COST-231 Hata model buttresses the need for developing different path loss models for different radio signals in different locations under different environmental factors. In addition, the finding of the study establishes a standard propagation path loss model that can be used for planning and designing efficient wireless communication link for terrestrial radio broadcasting station in the metropolis and any other environments with similar environmental factors.

Uma leitura decolonial sobre o ativismo judicial
Authors: Feijó Vladimir Pinto Coelho , Bicalho Thiago Filipe Martins
Published: March 2021

O presente artigo foi construído a partir de uma pesquisa bibliográfica, considerando a vertente jurídico-sociológica, para ponderar sobre o ativismo judicial como mentalidade jurídica colonizada. A pergunta de partida foi: existe uma alternativa decolonial de ativismo judiciário? Coletou-se argumentos sobre como o ativismo, apesar de ter produzido ganhos de efetividade para os direitos sociais, acaba sendo uma reafirmação da colonialidade do saber jurídico. Para chegar a esta conclusão, primeiro descreve-se o nascimento do Estado e do Direito modernos, o ajuste neoconstitucionalista e como, nas duas fases, a adoção na américa latina foi meramente simbólica. O uso do ativismo foi identificado como nova forma dos esquemas juspositivistas de estrutura hierárquica com processos que buscam identificar o melhor argumento. Como alternativa, apresenta-se o paradigma do Novo Constitucionalismo que prega a solução de conflitos pela mediação consensual e diálogo entre culturas e pessoas sem consensos prévios, especialmente consensos linguísticos. Enquanto as organizações da sociedade civil em países ocidentais optaram pela formação de coalizões para mobilizar o judiciário e através disso estimular a produção do direito, em outras sociedades latino-americanas os mesmos grupos sociais marginalizados reivindicaram deixar de serem marginalizados até que conseguiram implementar novo paradigma constitucional.

A Back-Door Entrance into Teaching Teachers
Authors: Lefoka Pulane
Published: March 2021

This paper is based on PhD research that was carried out at the National University of Lesotho’s Faculty of Education. The focus of the study was on the sources and application of professional knowledge among teacher educators. The content of the paper was drawn from the chapter on enactment of professional knowledge. All the research participants entered the teacher educators’ world through the backdoor; that is, some were invited by their teacher educators to work as teaching assistants while others applied to an advertised position. None of them had teaching in higher education credentials, hence back-door claim. Their major source of professional knowledge is experiential. Their professional lives have been shaped by their context. However, practice-based knowledge presents numerous challenges including lack of knowledge of the pedagogy of teaching student teachers and bias towards using transmissive methods of teaching.

This paper presents the results of petrographic study of sedimentary iron ore from surface strata of the Shendi-Atbara Basin, River Nile State, Sudan. The aims of this study are to investigate the geological behavior and geological conditions affecting precipitation of sedimentary iron ore. The methodologies have been used to realize the objectives of this study include field work, office work and laboratory work including thin sections and polished sections analysis. According to field observation sedimentary iron ore can broadly be considered as occurring in three major classes:Ferribands iron, ferricrete iron and oolitic iron ores. The modes of occurrence of iron ore were described at the outcrops and vertical sedimentary profiles revealed that the iron occurred in the study area at different types in stratigraphic sequence such as cap, bedded and interbedded conformable with Shendi Formation. Petrographic study of iron ore in collected samples using polarized microscope and ore microscope includes study of the textures and structures of ores to obtain ore history. The main types of textures and structures in studied samples are oolitic, granular, lamellar and bands.According to these results the origin of iron ore is formed by chemical precipitation during chemical weathering of surrounding areas in continental lacustrine environment. The iron ore in study area is potential for future mining works and steel industry

Pay attention to current conditions the current value of student care shows symptoms that are increasingly declining. This descriptive qualitative study aims to determine the process of instilling the value of low class students' social care and the forms of low class student social care values in elementary schools. Data collection by observation, interview and documentation. The results showed that the process of instilling the value of social care of low grade students was carried out through: 1) Integration in the personal development program in the form of routine school activities, spontaneous activities, exemplary, and conditioning; 2) Integration in subjects by inserting social care character values into syllabus and lesson plans, including social care character values in the learning process; 3) Integration in school culture in the form of integration in the classroom, school and non-school activities. Forms of social care values of low grade students include 1) Sharing food with friends; 2) Thanking people for help; 3) Mutual lending of peer learning equipment; 4) Collecting funds and goods that are still useful for victims of natural disasters.

At the origin of Italian Euroscepticism
Authors: Brunazzo Marco , Mascitelli Bruno
Published: March 2021

The dominant narrative about the virtue of European integration is no longer the mantra of Italian politics. Alongside those parties who inherited the traditional ‘Europhile’ position, one can find parties whose support toward the EU is uncertain (like Forza Italia) or openly questioning the integration process (such as the Lega, Fratelli d’Italia and the Movimento 5 Stelle). Moreover, Euroscepticism in Italy reflects a deep change in the public opinion towards the EU: the consistent traditional supportexpressed by the Italians has of recent become more volatile and even critical. This article provides a brief look at changes in Italian positions on European integration, with a focus on the sentiments of both public opinion and the political elites, particularly after the Italy’s entry into the Eurozone in 1998.
The evolving role of EU Regional Policy: Implications for Australia?
Authors: Wilson Bruce
Published: March 2021

In 2013, ANZJES published an article on the significance of European Union (EU) Regional Policy in the process of European integration and its implications for Asia. Over the past decade, EU Regional Policy has evolved considerably. It is still centred on facilitating European integration, but also assumes a much more central role in focusing attention on harnessing resources, intellectual and economic, in order to address major societal missions. Regional Policy, or Cohesion, funds constitute approximately one third of the total European Commission budget and are, therefore, not only an important resource for integration, but also for addressing the wider priorities around the European Green Deal, and indeed, the planet. This is evident in the proposed Multiannual Financial Framework agreed by the European Council for 2021-27, in which Cohesion funding is seen to be a crucial resource for economic and social recovery from the COVID-19 crisis. This article reviews the evolution of this thinking in the last decade and considers its growing international significance. Whilst not necessarily imagined in 2010, when the EU established its European External Action Service (EEAS), a focus on regions and their innovation systems has enabled the EU to strengthen its global influence significantly.
