Bell Beakers in the Masurian Lake District in north-eastern Poland – relics and identification issues
Authors: Manasterski Dariusz , Januszek Katarzyna , Cetwińska Aleksandra
Published: June 2022

Until the beginning of the 21st century it was believed that the north-eastern border of Bell Beaker influence reaches the Vistula River basin. Recent discoveries in the North Podlachian Lowland provided grounds for verification of this belief, particularly with regards to the Masurian Lake District, which used to be considered as a territory of intensive activity of the Iwno Culture – a propagator of Bell Beaker influence in this part of Europe. This verification included materials of the highest diagnostic value – pottery and flint artefacts from two best-researched sites in this area: Ząbie X and Szestno II. As a result, fragments of pottery vessels and flint artefacts which can be conclusively associated with Bell Beakers were identified and their analyses revealed that these objects were not connected with the local Iwno Culture, but rather resembled both the materials recently unearthed in the North Podlachian Lowland and corresponding materials from the area of the Atlantic coast. This might mean that people carrying the Bell Beaker cultural package reached the area of the Masurian Lake District and North Podlachian Lowland in the Late Neolithic.
Development of a translation device for axiological-semantic density in political news articles: wording and charging
Authors: Siebörger Ian , Adendorff Ralph D.
Published: June 2022

The concept of axiological-semantic density from Legitimation Code Theory (LCT) is extremely helpful in analysing political knowledge-building, as it describes the strength of relations between various people, political stances and moral judgements, enabling these to be positioned in relation to each other. We present a multi-level translation device designed to identify strengths of axiological-semantic density in political news articles from the Daily Sun, South Africa’s most popular tabloid newspaper. This translation device was devised through analysis of selected texts from a corpus of 516 articles published between January and June 2015. It was developed through a collaborative process involving the first author and a team of student research assistants. The final translation device has five tools, of which two, the wording and charging tools, are described in this article, and then illustrated using an example analysis of a Daily Sun political news article. Both tools reveal insights into South African political discourses and ways in which axiological-semantic density can be enacted in future research. Making axiological-semantic density visible using such a translation device also has practical applications in assisting readers to understand the ways in which publications such as the Daily Sun position political parties, enabling them to engage more constructively in discussions on the country’s future.
Does Institutional Quality Matter for the IDP Hypothesis? Evidence from Emerging Europe
Authors:   International University of Sarajevo, Bosnia and Herzegovina, Ganić Mehmed
Published: June 2022

The study empirically explores the relationship between OFDI and the home country’s institutional quality by employing a panel of 23 European emerging countries between 2000 and 2019. In doing so, the study employs the VECM estimation procedure. The key findings of this research indicate that the rate of adjustment to reach long-run equilibrium in European post-transition countries is lower than in European transition countries. In conclusion, there is evidence, for the period being investigated, of causality between the home country’s institutional quality and OFDI in both regions. Also, most of the transition countries are still in the process of building the institutional environment, with many institutional voids and different starting points of their internalization process. In fact, most of the countries, especially European transition countries, are in stage 2 or stage 3 of their investment development path (IDP) development, where IFDI stock still remains higher than OFDI stock.

Suez Canal: The Modern Maritime Wonder
Authors: Akhter Hossain Khandakar
Published: June 2022

Canal Suez is one of the supreme engineering wonder of the world. The canal is owned and maintained by the Suez Canal Authority (SCA) of Egypt. Suez Canal is connecting Mediterranean and Red Seas and was officially opened on Nov 17, 1869. This maritime wonder took more than 15 years to plan and build. The Canal construction was repeatedly hundred by political disputes, labor shortages and even a deadly cholera outbreak. When finally completed, the 101 NM long waterways permanently transformed international shipping by allowing vessel to skip the long and deceitful transit around the southern tip of Africa. The Suez Canal has enjoyed increased traffic in recent years, with roughly 50 ships passing through its waters every day. However, the canal is still hampered by its narrow width and shallow depth, which are insufficient to accommodate two way traffic from modern tanker ships. In 2014, Egypt’s Suez Canal Authority announced an ambitious plan to deepen the canal and create a new 22-mile lane branching off the main channel. Preliminary work has already begun which Egyptian authorities claim could more than double the canal’s annual revenue by 2023. It is an interesting reviewed paper based both on primary and on secondary information and some critical analysis. Paper describes history, engineering wonders, interesting fact and figure of Suez Canal and excellent ambition of human and present status of one of the maritime success of shipping trade that improving the international maritime business and transportation.

Toxicity to residual chlorine: Comparison of sensitivity of native Arabian Gulf species and non-native species
Authors: Saeed Suhur , Deb Nandita , Varghese Linso , Thornhill Bernice , Al-Shaikh Ismail , Warren Christopher
Published: June 2022

Chlorine is extensively used as a powerful oxidizing agent in the countries surrounding the Arabian Gulf for water treatment and biofouling control. Its usage has been increasing significantly as demand for water grows considerably both in industry and for domestic use. This is due to the fact that it is a well-tested technology, has had a history of long-term worldwide industrial use and is of acceptable cost. While the Arabian Gulf waters support a range of coastal and pelagic marine habitats including mangrove forests, seagrass meadows and coral reefs, marine organisms in these waters are living close to their tolerance limits due to the extreme environmental stressors like temperature and salinity. Anthropogenic stressors such as chlorine may further exacerbate these natural stressors. In seawater, chlorine produces a mixture of hypochlorous acid and hypochlorite ion. These rapidly react with the bromide ion to form a mixture of hypobromous and hypobromite ion. Total residual oxidants formed by chlorination although are short lived and not persistent in seawater, they can be quite toxic. In the present study, toxicity data were obtained from 7 acute toxicity tests and 3 chronic toxicity tests using Arabian Gulf aquatic species from different trophic levels. The study also examined the effect of temperature and developmental stages on toxicity of chlorine. Furthermore, differences in the species sensitivity distribution between native and non-native species were compared. The main finding of the study showed that there was no significant difference between native and non-native species for chlorine toxicity. This would suggest that toxicity data from different geographic region can be used in deriving site- specific ecological risk assessment of chlorine. Keywords: Chlorine; Arabian Gulf; acute toxicity; chronic toxicity; risk assessment; species sensitivity distribution;
Unpacking sustainability
Authors: Cannon Clare E. B. , Dobbin Kristin Babson
Published: June 2022

To advance sustainability globally and equitably, a holistic approach to investigating economic, environmental, and social systems is needed. We extend sustainability research by considering gender explicitly in these efforts, employing feminist political ecology to improve understanding of such complicated interrelationships and to analyze the drivers and impacts of global unequal ecological exchange, namely the ecological deficit of countries to support economic value elsewhere. We employ structural equation modeling to test hypotheses connecting gender equity, neoliberalism attributes (e.g., size of government, degree of regulation), and overshoot. Our findings reinforce aspects of existing theoretical frameworks, including clear support for strong sustainability theories, such as unequal ecological exchange, and complicate dominant development narratives that modernization increases gender equity. We demonstrate the empirical importance of including measures of gender equity in sustainability research and the theoretical importance of feminist political ecology’s contribution to understanding gender and environment as linked oppressions not just for conceiving of new imaginaries but also enacting them.
Understanding Leadership for Adaptive Change in Catholic Schools: A Complexity Perspective
Authors:   Boston College, Miller Andrew F. , Noble Anna ,   Boston College, McQuillan Patrick ,   Boston College
Published: June 2022

In an era of decline and crisis, Catholic school leaders have been encouraged to find innovative ways to enhance a school’s operational vitality. Yet to this point, most research on educational change in Catholic schools has focused on the technical tasks school principals can take to “save” individual schools. In this article, we apply a complexity perspective to educational change leadership in Catholic education: leadership for adaptive change. Based on a new empirical analysis of the professional experiences of two Catholic school principals working at four different parish schools, we demonstrate in this article how leadership for adaptive change can operate in Catholic elementary parish schools and assess whether and how the attributes of complex adaptive schools were present in these four elementary schools. We also highlight the organizational and social conditions these two principals confronted that both undermined and promoted their ability to lead for adaptive change at these four schools. Ultimately, we suggest in this article the utility of using a “complex adaptive” approach to understanding change leadership in Catholic elementary schools as opposed to “technically rational” approaches commonly found in contemporary Catholic school leadership research.
The Potential of Catholic Schools: Public Virtues through Private Voucher
Authors:   Washington College, Prud’homme Joseph
Published: June 2022

Recent US Supreme Court cases signal a likely increase in calls for K-12 school choice programs that include the option of enrolling in religious schools. In turn, criticism of religious school-inclusive school choice programming is likely to shift to policy and values-based critiques. This article addresses two allegations of Catholic primary and secondary school deficiencies in achieving objectives important to a pluralist society, allegations that would invalidate indirect state support of Catholic schools. By analyzing the aesthetics of Hans Georg Gadamer and Aristotelian moral theory in light of American Catholic schools’ potential, this paper rejects claims that Catholic education is unlikely to meet core needs of a contemporary pluralist society.
Social Work with Individuals Having Alcohol Usage Problems: Overview of the Situation in Lithuania
Authors: Kievišienė Justina
Published: June 2022

This article analyzes social work with individuals having alcohol usage problems in Lithuania. In this survey-based quantitative research, frequency data was gathered to examine the usage of methods, services, practices and challenges in this specific area. The results revealed a strong orientation towards individual intervention in social work with individuals having alcohol usage problems. Uncommon usage of group, community or network methods was observed in research data. Low usage of social action or social welfare methods might represent a weak policy-making function. Among services, providing information, consultation and representation are the most often applied. Lithuanian social workers also favor social skills development and family consultation in terms of specific practices, as those are the most often used. Finally, professionals acknowledge that low the motivation among clients to change is among the biggest challenges in this field. Improvements in social work with individuals having alcohol usage problems could be made through the enhancement of skills and practices that are the most effective in the substance abuse area, although relatively rarely used in social work in Lithuania.

Authors: Curay Jenny , Mantilla David , Brito Jorge
Published: June 2022

The subtropical forests of the Pacific slope of Ecuador lie within a region of wide biodiversity due to the biogeographic influence of Chocó. However, the diversity of small non-volant mammals in these forests is poorly understood. We conducted surveys at seven localities in 2020 and 2021 in Lita, northwestern Imbabura province, Ecuador. Sampling was done on an altitudinal range of 1,314–1,812 m. We used a combination of techniques (Sherman, Tomahawk, and pitfall traps) to capture non-volant small mammals. Our accumulated trapping effort was 2,724 trap/nights. We recorded 180 individuals of 23 species, of which rodents were the most diverse with 17 species, representing 73.9% of the composition. The record of Pattonimus musseri Brito et al. (2020) stands out, representing both latitudinal and elevational altitudinal range extensions. Finally, our results indicate that Lita is a natural area with a high concentration of non-volant mammals in the northwestern Ecuadorian subtropics.

Authors: Hue Pham Thi , Tuyet Nguyen Thi Anh , Co Hoang Xuan
Published: June 2022

The aim of this study is to evaluate energy consumption and greenhouse gas (GHG) emissions from Vietnam’s road transport service through establishing scenarios in 2015-2050. Four scenarios are firstly developed toward improving energy efficiency, floating automotive industry strategy and then energy demands, GHG emissions for road transport in these scenarios are estimated. Transport demand, technology penetrative rate, fuel type, fuel economy, emission standard and influence of other factors on emissions are bases of the selected input data. Calculator 2050 is used as a support tool of interface and calculation. The results are shown as following: Energy consumption and GHG emissions of road transport service will reach 11.28 Mtoe and 32.07 MtCO2e in 2030 as well as 36.95 Mtoe and 105.04 MtCO2e in 2050 in basic scenario, respectively, with annual average growth rate reach 6.4%. The contribution to increasing the energy consumption and GHG emissions of freight transport service is higher than that of passenger transport service. In the best case, energy consumption and GHG emissions are reduced by 27.4%, 30.3% in 2030 and 37.8%, 50.7% in 2050 compared to the basic scenario. This reduction is mainly due to the use of alternative fuels/vehicles in these activities.

Published: June 2022

ABSTRACT: This research carried out a bibliometric analysis and literature review on the production of gelatin-based films for application as food packaging, addressing the main advances and limitations. The search for articles was performed in the Scopus database, and bibliometric data were obtained using the Bibliometrix tool (RStudio software). It was observed that a wide variety of compounds can be incorporated into gelatin films to overcome the limitations related to their high solubility and low mechanical properties, as well as to obtain active or smart functions. Among the most reported compounds were essential oils, pigments extracted from vegetables, and other antimicrobial agents. The most reported foods as an application matrix were meat (fish, chicken, and shrimp), milk, cheese, and minimally processed fruits. Even with promising trends, the biggest challenge for large-scale applications is to obtain easily degradable biopolymers with structural and functional stability similar to synthetic polymers. Thus, a greater focus on this theme in research may favor significant advances in the use of these packages and positively impact several of the Sustainable Development Goals, as recommended by the United Nations.
Environmental factors on seasonal germination of different weedy rice(Oryza sativa L.) biotypes
Authors: Kaya-Altop Emine , Uysal Meral Sahin , Haghnama Kianoosh , Mennan Husrev
Published: June 2022

ABSTRACT: Weedy biotypes of Oryza sativa L., (weedy rice) are a serious threat to rice production because of their flexibility in seed germination timing, variable growth forms, and high genetic diversity. Experiments were designed to determine the effects of storage conditions, osmotic stress, pH, salt stress, and burial depth on germination of weedy rice seeds in flooded or non-flooded conditions. Mature weedy rice seeds were gathered from rice fields in the different regions of Turkey. Three biotypes were selected and classified according to awn length; long awn, short awn and awnless. Seasonal germination patterns of weedy rice seeds in the laboratory after retrieval from various depths and timing were affected by burial depth, water regime, and exhumation timing across the treatments for all biotypes. The long and short awn biotypes had higher germination rates than the awnless biotype and did not have a seasonal germination pattern. Seed germination was initiated in the spring, peaked in summer and declined in the fall in flooded and non-flooded treatments for the awnless biotype. The most distinct differences in seedling emergence patterns were observed in awnless and long awn biotypes, and they emerged from 10 cm depth. Our results suggested that flooded conditions reduced the germination of weedy rice biotypes. Flooding rice paddies for a period of time after harvest may improve weedy rice control and decrease the weed population. In addition to deeper cultivation would be more effective in controlling all weedy biotypes since the majority of weed seedling emergence was from shallow depths.
Substantive rationality of impression management: An analysis of corporate reports of JBS
Authors: Cruz Juliana C. S. , Rodrigues Marly D. , Araújo Risolene A. M. , Silva Adriana R.
Published: June 2022

ABSTRACT Objective: To investigate the substantive rationality inherent to the practice of impression management (IM). Originality/value: Based on the taxonomy created by Merkl-Davies and Brennan (2011), it is analyzed: 1. the discussion under the sociological perspective; and 2. the actions of substantive rationality in the management of impressions that can manifest through actions of symbolic management. This study responds to the call of Merkl-Davies et al. (2011) by putting into practice an unconventional analytical model based on the use of the corporate reports (annual and sustainability) of the company JBS with special attention to the “Carne Fraca” [Weak Meat] Operation. Design/methodology/approach: A content analysis of the accounting narratives of JBS’ corporate reports between 2015 and 2018 was carried out. Findings: Accounting narratives suggest evidence of IM and substantive rationality. The preparers of the corporate reports used substantive rationality to legitimize the company’s actions, with the most significant manifestations of this practice in the 2017 report, the year of the “Carne Fraca” operation. The implications of this research lie in demonstrating evidence that guides companies regarding the use of accounting narratives to convince society of their actions as consistent with the structure of social rules and norms. Furthermore, we emphasize that the accounting narratives must be analyzed with caution since they can be elaborated under the influence of the manager’s opportunistic behavior.
Anísio Teixeira e o “direito à educação” – ideias que evocam Dewey e inspiram Freire
Authors: Henning Leoni Maria Padilha
Published: June 2022

Resumo Este artigo trata centralmente da questão do direito à educação, tendo como autor principal Anísio Teixeira, que tomou para si o problema das desigualdades definidoras dos papéis sociais atribuídos historicamente aos brasileiros, resultando em privilégios. Nesse ordenamento fenomênico, a educação se encontra comprometida com o espelhamento desse estado de injustiça, fato que poderia ser desconstruído pelo fortalecimento da escola pública e de qualidade, promovida por uma pedagogia renovadora. A partir de John Dewey, Teixeira viu-se inspirado pelas ideias do progressivismo, animando-se para promover as transformações necessárias para a passagem de uma sociedade arcaica para outra modernizadora. Paulo Freire ocupou-se de problemas semelhantes, mas sugeriu uma pedagogia que pudesse libertar os indivíduos das condições opressivas, cujo mecanismo escolar da educação bancária contribuía para a realização da dominação. Vendo conexões entre esses autores, que pretenderam impulsionar o desenvolvimento por ações pedagógicas inovadoras, fundamentamo-nos nas obras desses intelectuais que permitiram a discussão, o aprofundamento e as conexões entre o direito à educação e a democracia.
Anísio Teixeira and the “right to education” – ideas that remember Dewey and inspire Freire
Authors: Henning Leoni Maria Padilha
Published: June 2022

Abstract This article deals centrally with the issue of the right to education, with the main author Anísio Teixeira, who took on the problem of defining inequalities in the social roles historically attributed to Brazilians, resulting in privileges. In this phenomenal order, education is committed to mirroring this state of injustice, a fact that could be relaxed by strengthening the quality of public school promoted by a renewing pedagogy. In John Dewey, Teixeira was inspired by the ideas of progressivism and encouraged to promote the necessary transformations from an archaic society to another modernizer. Paulo Freire dealt with similar problems, but suggested a pedagogy that could free individuals from oppressive conditions, whose school mechanism of banking education contributed to the achievement of domination. We saw connections between these authors who intended to boost development through innovative pedagogical actions. We based on the works of these intellectuals that allowed discussion, deepening and connections between the right to education and democracy.

Published: June 2022

ABSTRACT Objective To assess the knowledge of newly graduated nurses about Specific Precautions/Isolation measures. Method A cross-sectional descriptive-exploratory study with a quantitative approach was conducted in a private hospital in São Paulo in February 2019. The researcher approached the nurses waiting for the “Junior Nurse” position selection process to participate in the survey. The participants answered a validated instrument with 29 multiple-choice questions, divided into five thematic categories. A score of 7.0 (from zero to 10) was defined as the cut-off point. The R Core statistical package and the lme4 for generalized mixed models were used for data analysis, with a significance level of 5%. Results 190 newly graduated nurses participated in the study, with an overall knowledge of Specific Precautions score of 5.82, with the highest mean (7.9) in the “Personal Protective Equipment” category. In the other four categories, the nurses scored below 7.0, with the lowest score (4.35) in the “Care for the environment”. Conclusion and Implications for the practice The study showed a deficiency of Specific Precautions knowledge among newly graduated nurses, with implications for the patients’ and healthcare professionals’ safety from graduation practice (internship) to the beginning of their professional career.
ATUAÇÃO DO MINISTÉRIO DA SAÚDE NO ENFRENTAMENTO À PANDEMIA DE COVID-19 NO BRASIL

Published: June 2022

Desde o início da pandemia de covid-19 no Brasil em fevereiro de 2020 o governo federal optou por seguir um caminho diferente do que indicavam as evidências científicas para agir no enfrentamento à doença. Este trabalho objetivou apresentar os principais acontecimentos e discutir a atuação da direção do Ministério da Saúde, em sua relação com a Presidência da República, no enfrentamento à pandemia de covid-19 no Brasil. Trata-se de pesquisa documental exploratória de publicações disponíveis em portais de notícias nacionais, organizadas cronologicamente e com base na atuação de cada um dos ministros da saúde. Identificou-se uma série de medidas equivocadas, infundadas e negacionistas fortemente orquestradas pela Presidência: rotatividade de ministros da saúde; fragilização da Atenção Primária à Saúde; minoração das relações interfederativas; morosidade no processo de vacinação; descaso com a ciência; inépcia na estratégia de testagem e distribuição de insumos; militarização da saúde; opacidade das informações em saúde; casos de corrupção; dentre outras. O principal desfecho desta atuação é evidenciado nas elevadas estatísticas de casos e óbitos por covid-19, reforçando o fato de que há em um curso uma política de racismo de Estado no Brasil, atrelada ao desmonte e desfinanciamento do Sistema Único de Saúde.

Narrow pelvis is characterized as an insufficient maternal bony pelvis that does not allow for fetal transit due to a variety of factors. Animal immaturity is one of these reasons. This communication was written with the goal of documenting surgical management of dystocia and its impact on a two-year-old heifer who was with a full-term pregnancy. A vaginal delivery was tried but failed due to the narrow maternal pelvis. To avoid any post-operative problems, the surgical management was carried out under strict aseptically. A volume of 30 ml 2% Lidocaine Hydrochloride was infiltrated on left flank with inverted L-block techniques. While the cow was on her right lateral recumbency. The uterus was emptied of a deceased fetus but fetal membrane with the intact umbilical cord was returned back to the womb. Suturing was done using standard surgical procedures, and post-surgical care was followed-up for ten-days. The heifer was successfully rehabilitated.

Methods A follow-up study design was conducted from December 2018 to June 2019 to determine the effect of breed and factors affecting conception rate to artificial insemination in dairy cows, taking breed, age, parity, body condition and timing of insemination as risk factors. The demographic factors were recorded by interviewing the owners. Most of the cows were examined for pregnancy diagnosis by rectal palpation of the genital tract at 60-80-days post-artificial insemination. Results Out of 114 artificially inseminated cows/heifers, 59 became pregnant, giving an overall first service conception rate of 51.8%. Although the breed, age, parity and body condition score did not affect the conception rate significantly, the pregnancy rate was better in the cross-breed (62.5%), in cows of 5-7-years of age (54.6%), in cows of parity 2-3 (59.2%) and in cows of good body condition score (57.7%). The conception rate in cows inseminated at 12-18-hours after the onset of estrus was significantly higher (62.3%) than those inseminated after 18-hours (31.2%) and before 12-hours (52.4%) after the onset of estrus. Therefore, cows with good body condition score (BCS) and artificial insemination (AI) service at 12-18-hours after the onset of estrus are the best choice of selection for obtaining the best result in the first service conception rate to AI in dairy cows/heifers. Conclusion This study reveals that the conception rate was influenced by the time of AI, so awareness should be given to cattle owners, as they should give AI for their cattle at optimum time within 12-18-hours after onset of heat sign.
Präventiver Mutterschutz (Folge 2): Greift das Mutterschutzgesetz bei Gefahrstoffexposition zu kurz?

Maßgeblich für den Schutz des ungeborenen Lebens vor Gefahrstoffen ist die Exposition des Embryos. Dessen Gefährdung beginnt aber möglicherweise vor Erkennung und Meldung der Schwangerschaft und kann bei Gefahrstoffen mit längerer Halbwertszeit schon vor der Schwangerschaft ihren Ursprung haben. Daher ist das Mutterschutzgesetz in der ausschließlichen Anwendung auf gemeldete Schwangerschaften unzureichend und bedarf einer Neubewertung.

Independent Candidacy and Electoral Reform: New Nation Movement NPC v President of the Republic of South Africa
Authors: Pretorius Loot
Published: June 2022

In the New Nation case, the Constitutional Court declared the provisions of the Electoral Act that prevent independent candidates from competing in provincial and national elections unconstitutional. It ruled that the impugned provisions violated independent candidates' constitutional rights to stand for public office, to freedom of association and to dignity. In a minority judgment, Froneman J disagreed and held that the Constitution contemplates a right to contest elections as a party-nominee only. The differences between the majority and minority judgments are largely the result of distinct interpretive approaches. The majority conducted an analysis of the right to stand for public office within a restricted textual framework that has the potential to disturb the harmonious inter-relationship between the right and the electoral and parliamentary framework for its realisation. This result flows from the fact that the Constitution still reflects the exclusively party-based electoral and parliamentary systems of its predecessor in several important respects. At best, this situation may result in independents being largely at the mercy of political parties for meaningful execution of their legislative and oversight obligations. At worst, they may be excluded from exercising core parliamentary functions altogether. Therefore, to avoid disturbing the normative coherence between the right to stand for public office, the foundational democratic values, and the electoral and parliamentary arrangements, constitutional amendments appear to be necessary for the implementation of the court's order. In any event, expectations about the contribution to electoral reform of allowing independents to contest elections must be tempered by the low political impact of independent representatives on governance, as well as the ambivalence surrounding the democratic functionality of independent candidacy, when measured against the values of transparency and accountability.

En la presente investigación se analizaron los hábitos alimentarios, la variación alimentaria y las relaciones tróficas de los peces presentes en el tramo bajo del río Gaira, Sierra Nevada de Santa Marta, Caribe Colombiano. Los muestreos se llevaron a cabo en época de lluvias y en época seca, empleando dos atarrayas de diferentes ojos de malla. Se utilizaron métodos cuantitativos como coeficiente de vacuidad (CV%) e índice de importancia relativa (IIR%) para establecer los ítems alimentarios importantes en el contenido estomacal. Se utilizaron 231 estómagos en total, identificándose siete grupos alimentarios. Según sus hábitos tróficos, los peces se clasificaron, en época seca como omnívoros, con tendencia a la insectivoría, carnívoros y herbívoros. En época de lluvias, el ítem que presentó mayor importancia fueron los peces, apareciendo larvas de Sicydium salvani en el 95% del total de los estómagos analizados y, con el 78% de la oferta, fueron las que más contribuyeron con alimento, siendo devoradas tanto por peces carnívoros como omnívoros. En época seca, la oferta alimentaria fue suministrada por material vegetal en un 100% (algas, tallos y limo) y 74% detritus. Estos resultados evidencian que este sistema fluvial es capaz de mantener una comunidad diversa con suficientes recursos alimentarios disponibles.
Antibacterial activity of the Agaricus pampeanus (Agaricaceae) ethanol extract against Enterococcus faecalis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa.
Authors: Camacho-Suntaxi Tatiana , Sánchez-Loja Santiago
Published: June 2022

The macro fungi of the genus Agaricus have so far recorded many bioactive compounds with antibacterial properties as a product of their metabolism. However, in Ecuador, A. pampeanus or “Kallamba de finados” is a species studied for its ethnomycological uses and as part of the fungal biodiversity of the country. In this study, the antibacterial activity of the ethanolic extract of A. pampeanus was evaluated on four ATCC strains and the bioactive compounds present in the extract were identified. Initially, an ethanol extract of A. pampeanus was performed with the use of a Soxhlet extractor. To identify the extracted compounds, a gas chromatograph coupled to a mass spectrophotometer was used. With the mother extract, four solutions of the A. pampeanus ethanol extract (APE) were made at different concentrations, classified in APE1 (50.32 mg/mL), APE2 (40.24 mg/mL), APE3 (30.16 mg/mL), APE4 (20.12 mg/mL), which were subsequently used in the analysis of antibacterial activity, using the Kirby-Bauer technique. Six chemical compounds were identified; among them Eugenol was found as one of the main compounds. Out of the four concentrations, the A. pampeanus ethanol extract (APE1) was the most effective against Enterococcus faecalis, Staphylococcus aureus and Pseudomonas aeruginosa and categorized as sensitive, while Escherichia coli did not present any activity and was cataloged as resistant. The APE4 was not effective in any case. The antibacterial effect of APE was verified. Furthermore, A. pampeanus is more effective against Gram positive bacteria.
Internal Rebordering in the European Union: Postfunctionalism Revisited
Authors: Gruszczak Artur
Published: June 2022

The EU has been under severe strain as a free-travel area. The migration crisis of the mid-2010s and the current Covid-19 pandemic have exerted a negative impact on the freedom of movement in the EU and the undisturbed crossing of internal borders within the Schengen area. Direct effects and long-term consequences of the prolonged crisis have shown that the dynamics of integration, which are determined by spillover effects of transnational processes, are counterposed by a politicization of domestically-embedded issues of security governance. This assumption underpins the postfunctionalist approach to European integration proposed originally by Hooghe and Marks. The tendency towards longstanding derogations from the Schengen regime, termed “internal rebordering,” should be juxtaposed with efforts of the European Commission towards a full restoration of the Schengen area without controls at internal borders. The argument developed in this article holds that internal rebordering has been embedded in the logic of the EU as an area of freedom, security, and justice comprising the Schengen area as its territorial manifestation. The rebordering processes in the EU and in the Schengen area have questioned the principle of “constraining dissensus” underlaying the postfunctionalist approach.
Stochastic Model to Characterize High-Frequency Ground Motion at Depth Validated by KiK-Net Vertical Array Data
Authors: Hallo Miroslav , Bergamo Paolo , Fäh Donat
Published: June 2022

The design of important structures for earthquake resistance requires an assessment of the local seismic hazard. One of its essential components is a site response that evaluates the amplification and attenuation of ground motion on a local scale. The shaking on the ground surface (in which it is generally measured) differs from the one at a depth; therefore, there is a need to characterize the ground motion at depth for important underground structures and buildings with deep foundations. In this study, we introduce a method to characterize the high-frequency (>1 Hz) ground motion at depth. The method makes use of a novel stochastic model (SM) that relates the ground motion at depth and on the surface in the Fourier domain. The SM is physics-based, its spectral amplification resembles an empirical 1D site response, and it allows reliable full-waveform ground-motion predictions. The method is validated through the comparison with empirical surface-to-borehole amplification curves observed in 144 selected KiK-net vertical arrays in Japan. Using a frequency range of 0.1–50 Hz, we identified 36 and 83 sites with a good and partially good mutual fit of theoretical and empirical amplification curves, respectively. Finally, we demonstrate the performance of the method in two diverse applications. First, we design a Bayesian inversion of the empirical surface-to-borehole amplification to retrieve the S-wave velocity model and an effective value of t* (the path-integrated effect of the quality factor). This inversion is applied to all selected KiK-net sites. Second, we perform a full-waveform prediction of the ground motion at depth from surface recordings of the 2018 northern Osaka Mw 5.6 earthquake. Both of these applications demonstrate a good performance of our SM in a broad frequency range.
