Authors: Teles João , Do Nascimento Cristiano , Lunkes Rogério João , Schnorrenberger Darci , Rosa Fabrícia da Silva
Published: September 2023

Este estudo tem por objetivo identificar e comparar o perfil do controller hoteleiro da região sul do Brasil, com os do Reino Unido, Estados Unidos e China. A amostra é composta por 23 hotéis associados da ABIH localizados na região sul do Brasil. Metodologicamente a pesquisa se caracteriza como: descritiva, prática, de campo, survey, quali-quantitativa e aplicada. Dentre os principais resultados, destacam-se: a discrepância ainda existente em relação às oportunidades de ocupação do cargo de controller entre homens e mulheres nos quatro países mas, de maneira mais acentuada, na China, cuja proporção se aproxima de oito homens para uma mulher ocupando o referido cargo; a predominância de indivíduos na faixa de 30 a 39 anos atuando como controller; salienta-se a predominância na formação em Contabilidade dos controllers norte americanos e brasileiros; dentre as responsabilidades inerentes a atividade, no Brasil despontam práticas relacionadas ao orçamento e contabilidade financeira. Ressalta-se a importância que deve ser dispensada aos itens formação de preço, controle de alimentos e bebidas, auditoria noturna e em especial ao ambiente de trabalho, pois tais perspectivas de responsabilidade sob a supervisão de um controller pode ser salutar ao pleno e eficiente desempenho organizacional de empresas atuantes no setor de hotelaria.

"how to dance / sitting down"
Authors: Davidson Michael
Published: September 2023

The topic of aging has been somewhat overlooked in disability studies, perhaps owing to the adage that "everyone is disabled if they live long enough." If the life course is simply a state of debility, why create a distinct category for bodily and sensory impairment? Disability in old age, I argue, is not a mark of precarity but of capability. The work of writers and artists who continue to experiment formally while becoming increasingly disabled in later years (Beethoven, Henry James, Merce Cunningham) offers an opportunity to complicate " late style" as developed by Theodor Adorno and Edward Said and account for the role of complex embodiment in the production of new work. Finally, I consider Samuel Beckett, whose characters are often aging and disabled and for whom bodily and sensory decline are central to their ability to "go on."
Das Fremde als Entfremdung des Eigenen
Authors: Mack Edda
Published: September 2023

Die Akteur-Netzwerk-Theorie Bruno Latours kennt kein Konzept des Fremden. Dies mag irritierend erscheinen, bedenkt man, dass die Figur des Fremden eines der zentralen Schlüsselkonzepte der Soziologie darstellt. Von Simmel bis Schütz stehen Fremdheit und der Fremde stets im Spannungsverhältnis zum Eigenen, welches gerade in der Begegnung des Fremden besonders sichtbar wird. Mit Werkzeugen der Akteur-Netzwerk-Theorie entwirft Edda Mack eine soziologische Denkweise, die das Theoretisieren selbst in den Mittelpunkt soziologischer Forschung stellt. Am Beispiel der Fluchtmigrationsforschung zeigt sie auf, dass eine solche Denkweise in ihrer Umsetzung nah bei den Dingen von Belang bleiben kann.
Erzählte Herabsetzungen - herabsetzende Erzählungen
Authors: Deinzer Gabriel
Published: September 2023

Herabsetzungen prägen auf vielfältige Weise den Umgang mit migrierten Menschen in den europäischen Aufnahmegesellschaften - so auch in Italien, das sich seit den 1990er Jahren von einem Aus- zu einem Einwanderungsland wandelt. Diese gesellschaftliche Entwicklung findet seither ein breites kulturelles Echo und schlägt sich nicht zuletzt in zahlreichen italienischen Spielfilmen nieder, welche das Einwanderungsgeschehen thematisieren und die damit einhergehenden Herabsetzungsformen verhandeln. Gabriel Deinzer zeigt, dass dabei migrationsbezogene Invektivität nicht nur problematisiert, sondern zuweilen auch reproduziert wird. Daraus ergibt sich im Hinblick auf das untersuchte Filmkorpus ein Spannungsfeld zwischen erzählter Invektivität und invektiven Erzählungen.
[EXP]OSITION - Die Ausstellung als Existenzweise
Authors: Chernyshova Svetlana
Published: September 2023

Was zeichnet eine (Kunst-)Ausstellung aus? Und was kann es heißen, wenn wir diese nicht nur als eine ›institutionelle Ansammlung von Dingen‹ begreifen, sondern die Ausstellung ›ökologisch‹ verstehen - d.h. ihre ganz spezifischen Milieus, Praktiken und situativen Konfigurationen in den Fokus rücken? Svetlana Chernyshova nimmt eine ontologische Verschiebung vor, indem sie die Ausstellung als eine Existenzweise - [EXP]osition - herausstellt und diese als ein Resultat von vielfältigen ›Metastabilisierungen‹ begreift. Auf der Grundlage von acht Parametern entsteht so ein Modell, welches das komplex-synthetische Phänomen Ausstellung systematisch in seinen Ebenen verhandelbar macht. Dabei rücken neben deren ästhetischen und epistemologischen Bedingungen auch die politischen Implikationen ins Blickfeld und zeigen: Ausstellungen lassen sich diffraktiv denken.

Authors: Najam Laith A. , Yaseen Ali I.
Published: September 2023

The fundamental goal of this study is to measure the level of radioactivity in the soil of the area around Al-Hadbaa cement plant, also to evaluate the radiological hazard of radionuclide, gamma-spectroscopy with an HPGe detector with the crystal diameter of 70.6 mm and length of 70 mm has been used to estimate the specific activity of natural radionuclides 226Ra, 232Th, 40K, and artificial radionuclides 137Cs in the fifteen soil samples collected. The results show that the average concentration of specific activity of 226Ra, 232Th, 40K, and 137Cs was 11.17 ± 1.69, 13.38 ± 0.72, 158.36 ± 5.35 Bq/kg, and 1.52 ± 0.19 Bq/kg, respectively. The average specific activity of these radionuclides is discovered to be lower than the global average which is 33 Bq/kg for 226Ra, 30 Bq/kg for 232Th, and 400 Bq/kg for 40K. Radiological hazard indices are determined according to the activity concentration of the radionuclides in the area under study. The outcome of the radiological hazard index is within the globally recognized limit proposed by UNSCEAR which is 1000 μSv/y for annual effective dose and 290 × 10-6 for cancer risk, so it is possible to conclude that there are no radiological hazards as a result of radiation exposure to the workers working in the cement plant as well as the organisms living in the region.
The Effect of TikTok Live Streaming Shopping on Impulse Buying Behavior in The 2023 Global Crisis
Authors: Ardiyanti Vika Diyah
Published: September 2023

Various studies have proven the effectiveness of social media in influencing consumers. This is used by business actors to increase sales through social media. Especially now that entertainment media such as Tiktok also provide convenience by presenting the Tiktok shop and Tiktok live streaming shopping. The presence of TikTok live streaming shopping is increasingly spoiling TikTok users. In fact, many potential consumers who had no previous shopping plans suddenly made a purchase. This is called impulsive buying. Impulse behavior is certainly not wise to do during a global crisis like today. The decline in income levels requires people to downsize. This study aims to determine the effect of tiktok live streaming shopping on impulsive buying behavior in the era of the global crisis. From the results of research conducted on 100 sample people using a qualitative descriptive method, it shows that tiktok live streaming shopping has a significant effect of 38.5% on impulsive buying behavior. This is due to the affordable product selling prices, ease of communication between sellers and buyers, as well as attractive promos such as special prices when shopping during live streaming.

The effect of conceptions of learning and prior online course experiences on students’ choice of learning spaces for synchronous online learning during COVID-19
Authors: Zeng Lily Min , Bridges Susan Margaret
Published: September 2023

During COVID-19, universities are reconfiguring learning environments and increasing flexibility in course offerings. Teachers have found synchronous hybrid teaching challenging with many students preferring online to in-person classroom attendance. Understanding students’ decision-making as to where, when and how they choose to learn will be critical in informing the design of learning spaces and courses. This survey-based study of 369 undergraduates across disciplines explored the relationships between students’ backgrounds and psychological factors (self-efficacy for online learning, conceptions of learning, perceptions of previous online course experiences) and student choices of learning spaces for synchronous online learning. While pre-pandemic studies in Western contexts identified non-traditional student characteristics as major factors associated with students’ choices of learning spaces (i.e., learning online at home), this Hong Kong study found significant associations between undergraduates’ choices, their origin and the disciplines. Logistic regression indicated those who preferred stimulating education and cooperative learning or perceived their previous online course experiences as having clearer goals had greater odds of attending classes synchronously online on campus from locations different from the scheduled teaching spaces. Qualitative analysis suggests personality, self-regulation and the university’s social and organisational structures as factors to consider in future studies of student choices of learning spaces.
Implications for practice or policy:

Higher education providers may need to diversify course designs to cater to undergraduates’ different hybrid learning preferences and expectations in the post-pandemic return to campus.
The first step for online course teachers is to help their students to build a higher level of self-efficacy for online learning.
Course teachers can motivate students to take courses online by clarifying their course goals and standards.
Modulation of pain perceptions following treadmill running with different intensities in females
Authors: Zi‐Han Xu , Nan An , Rui Chang Jeremy , Yong‐Long Yang
Published: September 2023

We aimed to compare the effects of three intensities of treadmill running on exercise‐induced hypoalgesia (EIH) in healthy individuals. We anticipated that the primary and secondary changes in pain perception and modulation may differ between running intensities. Sixty‐six women were randomly assigned to one of three treadmill running intensities for 35 min: 40% reserved heart rate (HRR), 55% HRR, or 70% HRR. The effects of EIH were assessed using pressure pain thresholds (PPT) and tolerance thresholds (PPTol). We measured conditional pain modulation (CPM). Compared with baseline, PPT and PPTol significantly increased in all groups during running and at the 5–10‐min follow‐up. The PPT and PPTol changes in the moderate‐ and low‐intensity groups were significantly higher than those in the high‐intensity group during running and 24 h after running, while the CPM responses of the high‐intensity group were significantly reduced at the 24‐h follow‐up. Moderate‐ and low‐intensity running may elicit significant primary and secondary (persisting over 24 h) EIH effects and increase CPM responses in females. However, high‐intensity running induced only limited analgesic effects and reduced CPM responses, which may be attributed to the activation of endogenous pain modulation.

Modeling and dynamic analysis of functionally graded porous spherical shell based on Chebyshev–Ritz approach
Authors: Lu Jili , Yang Qingyun , Meng Zhongliang , Yang Kang , Xu Wei , Chiu Ching Vincent
Published: September 2023

This study proposes a unified modeling method to investigate the dynamic behaviors of the functionally graded porous (FGP) spherical shell with elastic boundary conditions. First, three kinds of FGP distributed patterns are defined. Then, the first-order shear deformation theory is selected to build the governing equations of the spherical shell with elastic boundary conditions, which can be solved by the Rayleigh–Ritz approach. Moreover, Chebyshev polynomials of the third kind are selected as an admissible function to express the motion equation. With the constructed model, the correctness is verified by comparing the natural frequency and forced response obtained from both open literature and finite element method. Ultimately, the parameter study is conducted to conclude the effect of the design parameter on the dynamic characteristics of the spherical shell.

Authors: Demircioglu İsmail , Demiraslan Yasin , Aksunger Karaavci Funda , Gurbuz Iftar , Ozgel Ozcan
Published: September 2023

Aim: The aim of this study was to reveal the dimorphic structures of the foramen magnum and condyle occipitalis through an interspecies shape analysis and to determine the variability between sheep and goats.
Materials and Methods: The study includes data from 81 skulls (46 sheep and 35 goat) for this aim. The foramen magnum frame shape and the condyle occipitalis variation were determined using type I (anatomical) and type III (semilandmarks).
Results: Accordingly, was determined 30.76, 14.94 and 14.07 of the total shape variation of PC1, PC2 and PC3, respectively. It was determined that condylus occipitalis was primarily responsible for the shape variation according to PC1, and foramen magnum was responsible for the secondarly. It was found to explain the shape variation of the right condyle occipitalis to a great extent compared with PC2, while in PC3, it caused the entire right condyle occipitalis to explain the shape variation of the extreme lateral corner of the left condyle occipitalis and the left edge of the foramen magnum. The discriminant function analysis determined the Procrustes and Mahalanobis distances to be 0.12293879 (p < 0.0001) and 67.7482 (p < 0.0044), respectively.
Conclusion: As a result, the geometric morphometry method is regarded to be a useful tool for detecting changes in skull shape between species and can thus be used successfully for taxonomic, archaeological, and forensic research.

The Integration of Fintech and Banks: A Balancing Act Between Risk and Opportunity
Authors: Magdy Mohamed , Raouf Engy , Al-wakeel Nashaat
Published: September 2023

Financial technology is a widely discussed issue in industrialized countries, although it is relatively new in underdeveloped ones. With the emergence of financial technology (fintech), the banking sector has undergone significant changes. This paper investigates the impact of fintech, both inside and outside the industry (startups), on the profitability of the banking sector. Using a panel of eighteen Egyptian banks over the period 2017 -2021, the study employs a panel fixed effect, a generalized method of the moment and robust least squares models to examine the relationship between fintech and bank profitability. Our findings reveal a significant relationship between fintech and bank profitability, suggesting that the adoption of fintech inside the banking sector has a negative effect on bank profitability, while the adoption of fintech outside the banking sector has a positive and significant effect on bank profitability. These findings have significant implications for policymakers and industry stakeholders as they navigate the evolving financial landscape.

Drug therapy problem is an event involving drug therapy that actually or potentially interferes with the desired health outcomes. This study aimed to identify drug therapy problems encountered by hypertensive patients receiving care in BUK Clinic, Nigeria. It was a retrospective analysis of the medical records of adult hypertensive patients. A total of 206 patient folders were used for the study. The data were collected from the patient’s medical records using the Pharmaceutical Care Network Europe (PCNE) Classification tool Version 9.1 (PCNE, 2020). Data were analyzed using the IBM Statistical Product and Service Solutions (SPSS). The total number of drug therapy problem found was 314 of which majority was effect of drug treatment not optimal [P1.2] 155(49.4%) followed by adverse drug event [P1.3] 155(49.0%) and no effect of drug therapy despite correct use [P1.1] 5(1.6%) was the least type of drug therapy problem encountered. The major cause of drug therapy problem was inappropriate drug according to guidelines/formulary and inappropriate combination of drugs (C1.1 & C1.3) which account for 80(26.4%) of drug related problem. Prevalence of drug therapy problem was high (85.9%). Number of Antihypertensives on (P=0.022) and age(P=0.025) were significantly associated with increased drug therapy problem. Increased drug therapy problem can lead to increase in complications, increased hospital stays, emergency hospitalization and increased medical cost.
The Enduring Conflict in the Middle East: Irrational Causes and Viable Solutions that might begin with the Educational Means
Authors: Issa Mohammad Saleh Bani
Published: September 2023

This Paper aims at tracing and analyzing the irrational reasons that stood behind the lasting conflict in the Middle East with a refutation of its continuation according to the theory of recognition, as well as the viable solutions that might reduce the tension in the region and end the conflict for a long run.  It discussed the reasons that caused the conflict in the region to continue for more than hundred years for the benefit of the colonial states. The paper reached a point that the colonial states were behind the establishment of Israel in the region to be used as a functional state for the perpetuation of colonialism in the region, despite the existence of a Jewish homeland that had been previously announced in Birobidzhan, before the declaration of Israel in Palestine that is why seen today a rebellious state against the legitimacy and international law. The study concluded that it has become necessary to explain more precisely to the youth the cause of the suffering experienced by the peoples of the region of their various races and religions through educational curriculum at all levels of school and university. The study also concluded some proposals that may contribute to ending the unjust conflict gradually in the future.

Authors: Singh Vartika , Singh Jaswant , Chauhan Abhishek , Shukla Kartikeya
Published: September 2023

This study aimed to isolate a native fungal strain that was potent enough to curb the toxicity of azo dyes in textile effluent drain sludge. The native fungus, which has the potential to degrade several azo dyes under ‘non-sterile’ conditions, was isolated and identified as Trichoderma asperellum (TA). It was observed that the isolated strain was capable of decolorizing up to 71.42 %, 60.19 %, and 89.65 % of azo dyes (methyl orange, malachite green, and crystal violet, respectively) within a span of 14 days with an extensive range of temperatures (15°C-40°C) and pH (5-8) before optimization. The targeted dyes at concentrations of 100 mg/L, 200 mg/L, 300 mg/L, 400 mg/L, and 500 mg/L were decolorized after optimization. The maximum decolorization of methyl orange (MO), malachite green (MG), and crystal violet (CV) was 88.89 %, 71.09 %, and 92.75 %, respectively, at a dye concentration of 100 mg/L, pH of 6.5, and temperature of 25°C. The fungal isolate Trichoderma asperellum frequently contains chitinases, cellulose, and laccases. The findings of this study validated the potential of TA as an effective biocatalyst for the remediation of methyl orange, malachite green, and crystal violet in textile wastewater. The degradation products showed decreased toxicity to sprout seeds, such as Cicer arietinum (chickpea) and Vigna radiata (mung seeds), when compared to untreated wastewater.
Package Board Co-Simulation Using Equivalent Circuit Modeling Method for High-Speed System
Authors: Saini Lakshya , Agarwal Ravinder
Published: September 2023

This research paper focuses on the challenges of system-level simulations for high-speed data transfer and the importance of modeling methodology in achieving accurate results. The simulating of PCB alone without considering the package model is not enough. Instead, to ensure optimal system performance, simulating the packages and PCBs together is essential. When simulating the high-speed parallel bus at the PCB level, it's crucial to consider the package model. If the package model is missing, achieving successful results can be challenging. In this paper, a method is proposed for developing a package model that is specific to the nets required for simulation purposes. The paper explores the challenge of simulating high-speed interfaces with a DDRx example that includes an RLC package model. An interconnect model technique is developed to apply the package RLC model through the equivalent circuit modeling method for the high-speed DDRx test board. This solution aims to simplify the co-design process by using simulation and verifying the model with the assistance of an eye diagram of the data bus. The proposed package model reduces jitter in co-simulation and ensures timing compliance for high-speed interfaces.

OBJECTIVES

Studies concerning cardiopulmonary outcomes of adults born with congenital diaphragmatic hernia (CDH) are sparse. Moreover, they don’t include participants who have been treated with extracorporeal membrane oxygenation (ECMO) during the neonatal period. This study evaluated the cardiopulmonary morbidities in young adults born with CDH.

METHODS

We assessed 68 participants between the ages of 18 and 30 years. The assessment included auxology assessment, lung function tests, pulmonary imaging, cardiopulmonary exercise testing, and echocardiography.

RESULTS

Lung function parameters in the overall group were significantly worse than normal values. Mean (SD) scores postbronchodilator forced expiratory volume in 1 second were −2.91 (1.38) in the ECMO-treated and −1.20 (1.53) in the non-ECMO-treated participants. Chest computed tomography scans showed mild to moderate abnormal lung structure in all ECMO-treated participants, and to a lesser extent in non-ECMO treated participants. A recurrent diaphragmatic defect was observed in 77% of the ECMO-treated group and in 43% of the non-ECMO–treated group. Except for 2 cases with acute symptoms, no clinical problems were noted in cases of recurrence. Cardiopulmonary exercise testing revealed mean (SD) percentage predicted peak oxygen consumption per kilogram of 73 (14)% and 88 (16)% in ECMO-treated and non-ECMO–treated participants, respectively. The mean (SD) workload was normal in the non-ECMO–treated group (111 [25]% predicted); in the ECMO-treated group, it was 89 (23)%. Cardiac evaluation at rest revealed no signs of pulmonary hypertension.

CONCLUSIONS

In young adults who survived treatment of CDH, significant pulmonary morbidity, reduced exercise capacity, and frequent hernia recurrence should be anticipated. Lifelong follow-up care, with the emphasis on prevention of further decline, is to be recommended.
EVALUACIÓN DEL POTENCIAL AFLATOXIGÉNICO DE AISLADOS DE Aspergillus flavus EN MODELO DE MAÍZ IN VITRO
Authors: Moura Mendes Arrua Juliana , Cazal-Martinez Cinthia Carolina , Rojas Cinthia , Arrua Andrea Alejandra
Published: September 2023

Las aflatoxinas son metabolitos secundarios tóxicos para salud humana y animal producidos por Aspergillus flavus, y que contaminan a los alimentos a lo largo de la cadena productiva. Conocer y caracterizar la población fúngica presente en los alimentos nos sirve para estimar riesgo y diseñar medidas para mitigarlo. Siendo así, el objetivo de este trabajo es caracterizar el potencial toxigénico de aislados de Aspergillus provenientes de maíz en modelos in vitro. Para tal fin, se utilizaron dos aislados de A. flavus (CCM-AS02, CCM-AS29) y uno de Aspergillus luchuensis (CCM-AS04) de la colección de cultivos CCM-UNA. Para evaluar la producción de aflatoxinas en medio de cultivo sintético, se sembraron los aislados en agar coco y agar extracto de levadura y se evaluó la presencia de fluorescencia bajo luz UV (λ= 360 nm). Para determinar el tipo de aflatoxina, se realizó cromatografía en capa delgada. Por último, se realizó la infección in vitro con los aislados en estudio, de maíz avatí-morotĩ, adquirido comercialmente y se determinó la concentración de aflatoxinas con la prueba de inmunoensayo rápido de flujo lateral Afla – V®-VICAM®. Con los resultados obtenidos se puede concluir que los aislados de A. flavus CCM-AS02 y CCM-AS29 provenientes de maíz son aflatoxigénicos en las condiciones ambientales que simulan las naturales y que coinciden con las predominantes en nuestro país, por ello, es necesario crear conciencia del riesgo que representa la contaminación de los granos de maíz con Aspergillus y aflatoxinas y la necesidad de tomar medidas preventivas de control de este hongo.
MEIOFAUNA IN TROPICAL MONTANE STREAMS: BIOTIC AND ABIOTIC FACTORS REGULATING COMMUNITIES
Authors: Santiago-Vera Josue , Ramírez Alonso
Published: September 2023

Meiofauna is a group of heterotrophic organisms smaller than macroinvertebrates but larger than microfauna and characterized by groups such as testate amoebae, ciliates, and nematodes. They are a link between bacteria and resources and macroinvertebrates. However, tropical meiofauna is poorly studied; thus, our goal was to characterize meiofaunal community composition and abundance and assess potential environmental variables controlling these community dynamics. Monthly samplings of meiofauna were conducted for eight months in Quebrada Prieta, El Yunque National Forest, Puerto Rico. Sampling was made in 12 pools, and data on discharge, sediment characteristics, and biotic variables were also collected. A total of 62 meiofaunal morphospecies were identified, with nematodes dominating the community, followed by testate amoebae. Bacterivores and detritivores taxa dominated the community. Meiofaunal abundance was negatively related to discharge and positively to the percentage of coarse sand, nitrate, and macroinvertebrate abundance. The composition of meiofauna in Quebrada Prieta is like the composition reported for temperate streams, at least in major meiofaunal groups present. However, the community in Quebrada Prieta was dominated by testate amoebae. In contrast, temperate streams are often dominated by rotifers and nematodes. Both abiotic and biotic variables are important for meiofaunal communities in the headwater streams in Puerto Rico.

El biomonitoreo acuático participativo en América Latina y el Caribe, aún está en una etapa inicial. Este artículo revisa las experiencias registradas por investigadores e interesados en el tema, quienes atendieron la encuesta difundida por la red Macrolatinos@, además de ampliar la información a través de consulta en diferentes fuentes. La mayoría de las experiencias se han desarrollado a partir del 2010, principalmente en México y Colombia. Algunas son investigaciones y otras son requerimiento de consultorías. Es importante consolidar alianzas estratégicas, que generen solidez y credibilidad ante las entidades financiadoras. Una vez se tenga estabilidad y reconocimiento, y se cuenten con la participación tanto de académicos, científicos, gestores y ciudadanos, es fundamental mantener el mayor rigor técnico-científico. Todas las partes interesadas deberán destacar el potencial de los ecosistemas acuáticos dulceacuícolas, así como su importancia ecológica y social, con el fin de democratizar la ciencia y reducir la brecha que se tiene con la sociedad.

Los ecosistemas de agua dulce son una fuente primaria de servicios ecosistémicos esenciales para sustentar la vida y albergan una importante diversidad de especies acuáticas. El conocimiento sobre los macroinvertebrados acuáticos es precario en áreas declaradas como protegidas de Colombia. Este estudio tuvo como objetivo evaluar la diversidad de macroinvertebrados acuáticos bioindicadores y la calidad ecológica de hábitat del Parque Nacional Natural Selva de Florencia (PNNSF). Se recolectaron muestras de macroinvertebrados en seis microcuencas, cuatro ubicadas dentro del Parque y dos en la zona de amortiguamiento. Se realizaron análisis de diversidad de orden Q, variación en la composición de especies, y su relación con las variables fisicoquímicas. Para estimar la calidad del hábitat y del agua se aplicaron los siguientes índices: Índice de Integridad del Hábitat (IIH), Índice de Calidad del Ecosistema Ribereño (QBR), y el BMWP. Se recolectaron un total de 2894 macroinvertebrados acuáticos. Los órdenes más representativos fueron Ephemeroptera y Trichoptera. Los resultados del IIH fueron de moderada a alta integridad. El QBR fluctuó entre 65-100, indicando un nivel de calidad intermedia, buena y muy buena. El BMWP indicó que todos los afluentes estudiados se encuentran en la categoría de aguas muy limpias sin evidencias de contaminación. Finalmente, se concluye que el PNNSF y su zona de amortiguamiento están cumpliendo su función en la conservación de la diversidad acuática y se destaca la importancia de continuar con las estrategias de monitoreo implementadas en el PNNSF, a fin de asegurar el mantenimiento de su diversidad biológica e integridad ambiental.

Evaluating several biodiversity descriptors and considering several spatial scales might elucidate conservation issues and improve biodiversity monitoring in urban environments. We estimated species richness (order q = 0), Shannon diversity (order q = 1), and Simpson diversity (order q = 2) based on Hill numbers and performed cluster analysis and non-metric multidimensional scaling (NMDS) to compare seven urban micro-watersheds and a peri-urban site across a northern Andean city (Medellín, Colombia). We found 113 diurnal resident bird species: 50 (44 %) exclusively within urban sites, 21 (19 %) exclusively in the periurban site, and 42 (37 %) shared species. Some urban watersheds had similar bird species richness to the periurban site, but Shannon and Simpson diversities were always lower, showing decrease in local bird diversity when abundances were considered. Bird species composition differed between urban watersheds and the periurban site, with all urban watersheds grouped altogether by cluster and NMDS analysis, and the periurban site forming its own group. This suggests homogenization of bird species composition due to the species turnover decreasing across urban areas, with endemic, near endemic and rare species restricted to periurban areas where native forest remnants persist. Several scales of biodiversity and analysis at more local scales are needed to better understand biodiversity patterns across Andean cities and to design urban planning strategies that prevent biodiversity loss.

Biological control as part of integrated weed management represents an emerging and promising method to minimize the use and impact of herbicides on the environment. The objective of this research was to determine the ecological, phytosanitary, and agronomic status of weeds associated with crops in Antioquia, Colombia, and their potential to be chosen as candidates for biological control studies using pathogenic fungi. The research was carried out through a sampling of weeds in 35 agricultural farms, distributed in 11 municipalities and 10 different crops, on which population ecological variables such as frequency and dominance were evaluated; phytosanitary variables such as incidence and severity of foliar fungal symptoms; as well as some biological and anthropogenic aspects of these, through interviews with the farmers of each farm. The integration of these variables was proposed as an indicator to order and classify the plants according to their greater suitability to be subjected to biocontrol studies. A diversity of 75 weed species was found, with the Poaceae and Asteraceae families standing out, which together represented 43% of the population. 76% of this population presented disease symptoms, presumably of fungal origin, with the severity of up to 10% of the affected leaf area. In 22% of the species agronomic management difficulties greater than 50% were detected on a scale of 1 to 10. We indicate the following twelve weed species as candidates for future biological control studies through phytopathogenic fungi: Rumex crispus L., Digitaria horizontalis (Willd), Persicaria nepalensis (Meisn.) Miyabe, Thunbergia alata Bojer ex Sims, Melinis minutiflora Beauv., Paspalum paniculatum L., Pennisetum clandestinum Hochst. ex Chiov., Pteridium aquilinum (L.) Kunth, Sonchus oleraceus L., Erigeron bonariensis L., Bidens pilosa L., and Artemisia absinthium L. This is the first report of its kind in Colombia.

The nasturtium is diverse in bioactive compounds such as carotenoids, anthocyanins, and glucosinolates. Due to these attributes, it is important to apply them to novel foods, such as drinks. The objective of this study was to carry out a sensory evaluation for the viability of the addition of nasturtium extract to a beverage. Solvent extraction was performed at a solute-solvent ratio of 1:10 – 1:15 and ethanol purity of 45%, 70%, or 96%; antioxidant capacity was analyzed by the FRAP method and total phenolic compounds content by the Folin-Ciocalteu method. Additionally, three samples of the beverage that included nasturtium extract (extract content of 1000, 2500, or 5000 mg kg-1) were evaluated through a 5-point hedonic test and a preference test for the attributes of flavor, aroma, consistency, and the product as a whole. The samples with the highest solute-solvent ratio presented the highest antioxidant capacity, while the samples with ethanol purity of 45% and 70% obtained the highest content of total phenolic compounds. The sample with 1000 mg kg-1 of the extract was the best qualified in all the sensory attributes evaluated.

Strategies to overcome the sugarcane crisis in recent years are based on technological improvements in production, product diversification, exports, associativity and organic production. The purpose of this research was to analyze the technical, economic, social, and environmental implications of organic production of panela using ASOPROPANOC as a case study. The comparative analysis between the certified organic production system and the traditional system was based on documentary review, surveys with producers of the association, interviews to experts of the municipality, and observation in farms and sugarcane mills. The results show that the organic panela production system improves yields by 11% due to new varieties introduced and a more orderly production culture. Producing organic panela requires increases in investment by 46% but compensates with higher income and profits (16%); it also generates more jobs, improves worker  producer safety, their health and organization, and offers a better product to the consumer. The organic production system reduces between 50% and 150% the use of fuel materials per kg of panela produced as well as greenhouse gas emissions (between 1 and 91%) and water use (72%). Producing organic panela is an attractive option for growers.

Published: September 2023

Two separate independent experiments were carried out on agronomic approaches for controlling infestation by Phelipanche ramosa: the evaluation of two soil plowing depths (30 and 50 cm) and determining the resistance of two tomato cultivars (SV5197 and SV8840) to this parasitic plant. The experiments were performed in 2014 and 2018 seasons in naturally heavily infested fields in the province of Foggia (Apulia Region, south-eastern Italy). Based on our results, the 50 cm moldboard plowing depth reduced parasite infestation by 41.2% compared to that of 30 cm depth, commonly adopted by local farmers. Higher attachments to the host plants were observed in SV5197 than in SV8840, which could be correlated with the different level of resistance of the host plant. In both experiments, the highest Phelipanche infestation reduced the tomato yield but did not affect the fruit quality.
