REAL HARASSMENT, VIRTUAL ROBOTS? IMPLICATIONS OF ONLINE HARASSMENT GEARED AT VIRTUAL ASSISTANT BIA
Authors: Rodrigues Beatrys , Peruzzo André
Published: April 2023

The purpose of this article is to investigate emerging themes in YouTube's comments on the "BIA's New Responses Against Harassment" video campaign. In the video, Bradesco bank presents less subservient responses to verbal attacks and harassment frequently sent to the brand's virtual assistant, BIA. However, the comments in the video suggest a negative reception of the campaign by the audience, which can help illuminate broader discussions on social and symbolic asymmetries in feminized work rendered invisible by technology. The comments help us to reflect on understandings of what constitutes the human in artificial intelligence and how does the harassment of this virtual chatbot relates to the harassment suffered by women in virtual settings. To critically analyze these texts, we have taken a semiotic analysis of the audiovisual campaign based on Peircean semiotics of extraction and conducted a qualitative content analysis on 200 comments with the highest number of likes on the official Youtube video of the campaign, collected through Youtube Data Tools. Grounding our article in feminist technology studies and critical algorithmic research, we show how the audience reflects on the contradictory understandings of the humans rendered invisible in technology and that changing the materiality/code of technology is not enough to affect systems of gendered oppression.
ALGORITHMIC RESISTANCE IN EUROPE AND THE QUESTION OF COLLECTIVE AGENCY
Authors: Scharenberg Antje , Barassi Veronica
Published: April 2023

One of the key critical questions of our times is the understanding of how data, algorithmic logics and AI are altering our agency as citizens, and what forms of resistance and opposition are emerging on the ground. Some scholars have shown how algorithms both prohibit as well as aid activists’ agency (Milan, 2018; Treré, 2019; Etter and Albu, 2021), while others have focused on how individual activists challenge the power of algorithms and reclaim a sense of agency (Velkova and Kaun, 2021). Although over the last years much research has emerged on the civic and human rights implications of automated systems and algorithmic profiling, little attention has been paid to what was happening on the ground and how social movement actors were actively organising against algorithmic profiling.

In this paper, we draw on ten semi-structured interviews with actors from civil society or non-governmental organisations in Europe, who struggle against algorithmic decision making, and combine these findings with a qualitative textual analysis of ten campaign websites, both conducted in the context of a wider research project exploring the conflict over algorithmic profiling. The aim of the paper is to shed light on the discourses and practices of social movement actors when it comes to resisting algorithmic injustices. The key question that we are interested in addressing is to explore how – in the everyday resistance to algorithmic profiling – actors rely on three different strategies of action (algorithmic literacy, algorithmic regulation and algorithmic accountability).
REFUGEE OR EXPAT, HERO OR THREAT: MIGRANT QUERIES IN GOOGLE NEWS SEARCH RESULTS
Authors: Sen Indira , Ulloa Roberto , Urman Aleksandra , Makhortykh Mykola , Kacperski Celina Sylwia
Published: April 2023

Search engines play a gatekeeper role in current high-choice information environments. Considered a form of new media, users are still more likely to find and trust news found through search than social media sites. Indeed, search engines are one of the most utilised technologies to find political information, despite audits uncovering biases in their results, for example, towards national outlets over local ones. It is therefore important to keep in mind the potential of search results to affect public opinion. With this study, we investigate how Google search news headlines and snippets differ when varying migrant search terms (e.g., immigrant, refugee, expat). We employ computational text analysis methods as well as qualitative content analysis. Specifically, we employ an automated framework for detecting media frames, originally trained on Twitter data, and attempt to transfer it to news data; this framework allows for a categorization of data to frames of a generic-issue (economy, safety, health) and specific (hero:diversity, threat:jobs) nature. We evaluate its applicability for this novel data source and find that it performs well for frames related economy and security. Our next steps include analysing the results of other computational measures, namely, sentiment, agency and political outlet of the news item. We expect that sentiment and agency will complement the initial results we see based on media frames.
ARTIFICIAL INTELLIGENCE AS IM/MOBILITY: PRE-LIMIRARY THOUGHTS ON UNDERSTANDING THE USE OF AI IN IMMIGRATION SYSTEMS
Authors: Toupin Sophie
Published: April 2023

Technology, including artificial intelligence in im/migration service delivery and migration management have been widely deployed in EuroAmerica (Mongia, 2018; Walia, 2021). In Canada, Immigration Refugee Citizenship Canada (IRCC) has, in the past few years, secretly piloted an in-house built AI system for triaging im/migrant applications from China, India and the Philippines (Molnar & Gill, 2018). The 2 million immigration applications backlog in part caused by the COVID-19 pandemic has been used as a justification to accelerate the push for the adoption of AI in im/migration affairs stating the need to modernize, optimize and expedite immigration affairs. Building on AoIR 2022’s theme, I take a decolonial approach to the study of AI and im/migration issues. I follow the claim made by decolonial scholars (El-Nany, 2020) that it is necessary to go back in history in order to better understand current power relations, systemic racism and patriarchy, the ongoing dispossession and forced im/mobility of racialized populations located in the global South. I conceptualize the use of AI as immobility to show how populations become testing grounds to decide who is worthy of im/mobility. Methodologically, this conference paper is informed by access to information requests made to the government of Canada to shed light on the use of AI systems within the IRCC. In addition, this paper relies on desk research including newspaper articles, blog posts and podcasts by and with immigration lawyers, and parliamentary hearings.
“I LOVE THIS PHOTO! I CAN FEEL THEIR HEARTS”. HOW USERS ACROSS THE WORLD EVALUATE SOCIAL MEDIA PORTRAITURE
Authors: Trillò Tommaso , Hallinan Blake , Green Avishai , Kim Bumsoo , Mizoroki Saki , Scharlach Rebecca , Frosh Paul , Shifman Limor
Published: April 2023

Personal portraits on social media are value-laden constructs. Whether documenting graduation or flexing in the gym, users express what they care about and present it for others to evaluate. Since “global” portrait genres are produced and consumed in different locales, their interpretation and evaluation may vary. We thus ask: What values do people identify in different types of social media portraits? Which evaluative criteria do they use when judging them? An analysis of 100 interviews with users from Germany, Italy, Japan, South Korea, and the United States reveals that people consistently recognize genre-specific values in portraits and evaluate them through a narrow set of communication-related criteria. Such evaluations vary somewhat cross-culturally in ways that only occasionally match established comparative literature on values. We reflect on the relational character of the criteria adopted for the evaluation of portraits worldwide, highlighting its association with new modes of sociability in digital spheres.
DATA LITERACY COMPETENCE MODELS: A CRITICAL ANALYSIS OF THE NEW DIGCOMP 2.2 FRAMEWORK
Authors: Van Audenhove Leo , Vermeire Lotte , Demeulenaere Andy
Published: April 2023

What does it mean to be data literate? The answer to this question is not a simple one, as opinions differ. The majority of definitions seem to lean toward an instrumental framing. Increasingly, definitions are developed that take a more critical stance. However, understanding data is often neglected or underdeveloped. On March 22 2022, the Joint Research Centre of the European Commission published a new version of the Digital Competence Framework (DigComp) which is one of the most widely used frameworks.The new version 2.2 aims to ‘(…) engage citizens confidently and safely with digital technologies, taking account of emerging technologies, such as Artificial Intelligence (AI), the Internet of Things (IoT), (and) datafication’. In our contribution we aim to critically analyse the DigComp 2.2 framework. We do this by focusing on an analysis of the examples, as they are meant to: ‘(…) motivate education and training providers to update their curriculum and course material to face today’s challenges’. We have selected 84 examples out of the total 259 examples which have any bearing on data, algorithms and AI and have coded them. The main outcome of our analysis is that DigComp 2.2 manages to introduce new themes related to data and AI into its framework, be it with a very strong focus on AI. Much more emphasis is put on Understanding Data than on Using Data. DigComp 2.2. strongly leans towards a social science perspective on data literacy and less on a STEM perspective of data literacy.
EXAMINING THE EFFECTIVENESS OF ARTIFICIAL INTELLIGENCE-BASED CYBERBULLYING MODERATION ON ONLINE PLATFORMS: TRANSPARENCY IMPLICATIONS
Authors: Verma Kanishk , Davis Brian , Milosevic Tijana
Published: April 2023

Cyberbullying remains a significant problem for children that appears to have been exacerbated by Covid-19 related lockdowns, which moved a lot of children's offline activities online. Transparency reports shared by social network and gaming platform companies indicate increased take-downs of offensive and harmful comments, posts or content by artificially intelligent (AI) tools. Nonetheless, little is known about how such tools are designed and developed, what data they are trained on; and how this is done in practice. Many studies have discussed the opacity of such algorithmic _moderation, detection and prevention_ solutions, and called for their greater transparency to understand *how* and *what* user-interactive engagement features help in AI decision-making. This study examines a) the use of AI-solutions by social media and gaming companies to proactively address cyberbullying on their platforms, b) explore the current cyberbullying detection, prevention and proactive intervention strategies by such companies, and c) through comprehensive database search, review of existing computational literature on monitoring, detection and intervention strategies to address cyberbullying incidents amongst children. Our findings show that *very scarce* resources are available in the public domain to build AI algorithmic solutions to combat cyberbullying, and _little information_ is publicly available that would allow scrutiny of platforms' enforcement mechanisms.
DIGITAL MEDIA USE IN PUBLIC SPACE – AN OBSERVATIONAL STUDY OF SELF-SERVICE TECHNOLOGY DURING COVID19-PANDEMIC.
Authors: Waldenburger Lisa , Wimmer Jeffrey
Published: April 2023

The spread of digital media and devices in public spaces, so-called self-service technology (SST), is reaching more and more areas, so that it is now possible to interact with them for example when shopping, ordering or sending parcels. The use of SST is mostly supposed to be self-explanatory and intuitive, nevertheless it implicitly presupposes a certain degree of technical literacy. If this is not the case, digital stress can be triggered. But how do people deal with these devices, what role does the presence of others, the device itself and how it works, and the situational context plays? What influence do the measures to deal with the Covid-19 virus and the pandemic-related constraints have on the nexus of device, users and situation? This was investigated qualitatively in the present study by conducting participant observations. The advantage of this methodological approach is the consideration of contextual factors of the different practices and the direct observation of subjective evaluation processes on the use or even non-use of SST. This shows that characteristics of the devices – e.g. functionality, initiation and optionality – , situational contextual conditions – e.g. time and social pressure and spatial conditions –, and the subject themselves – e.g. age, routinisation and carried along baggage– play a role in dealing with SST and moderate the emergence of digital stress.

Authors: Sulistyawati Ni Luh Ketut Sri , Dewi Ida Ayu Sri Mahendra , Sihombing Irene Hanna H.
Published: April 2023

Organizational Citizenship Behavior (OCB) is a behavior which is not tied to any reward system, but can help the organization function effectively and efficiently. OCB can be improved with an emotional approach through Perceived Organizational Support and increase work motivation through Transformational Leadership. This study aims to determine the effect of Perceived Organizational Support and Transformational Leadership on Organizational Citizenship Behavior at Plataran Ubud Hotel & Spa. The sample used was 70 people, taken based on saturated sampling technique. The data analysis technique used is multiple linear analysis, while hypothesis testing uses t test and F test. The results show that, 1) Perceived Organizational Support has a positive and significant effect on OCB; 2) Transformational Leadership Style has a positive and significant effect on OCB; 3) Perceived Organizational Support and Transformational Leadership Style simultaneously influence OCB. The test results of the coefficient of determination show that the influence of Perceived Organizational Support and transformational leadership style on OCB is 55.1%. The implication of the results of this study is that to increase employee OCB, companies must increase perceived organizational support and adjust the leadership style that is applied.

Authors: Flores Ramos Janeth Liliam , Choque Laime Jorge Luis , Oropeza Siñani Gabriela del Rosario , Parada Calle Katherine Danitza , Balcazar Sturzl Claudia Cecilia , Mollo López Judith Rocío , Torres Cortez Omar
Published: April 2023

El Diente de Turner se define como un defecto localizado que cursa con hipoplasia y/o hipocalcificación de la superficie del esmalte, donde las piezas deciduas con infección periapical o con algún trauma pueden interferir en la formación de la matriz o calcificación del diente permanente y producir una alteración en la estructura del esmalte. La hipoplasia de Turner afecta exclusivamente a los dientes permanentes.

Se trató un paciente de sexo masculino de 16 años con características de hipoplasia de esmalte (la cual presentaba una estética desfavorable con sensibilidad dentinaria y mala oclusión con susceptibilidad a caries). Una opción de tratamiento de este defecto fue realizar una ameloplastía reconstructiva con la finalidad de conservar la vitalidad del diente, la cual dio un resultado satisfactorio, recuperando la estética y funcionalidad de la pieza dentaria.

Published: April 2023

Dentro la atención geriátrica, el obstáculo que se presenta al momento de valorar, detectar y tratar a los adultos mayores se enfoca en producir una serie de acciones adversas al no contar con un diagnóstico precoz de las alteraciones y afecciones en la esfera física (donde se toman en cuenta los cambios asociados a la enfermedad y sus manifestaciones clínicas), funcional (donde se aprecian los cambios en la ejecución de actividades de la vida diaria), cognitiva (asociada a la conservación de la inteligencia) y la social (que toma en cuenta las relaciones con el medio externo). Mediante este sistema de evaluación y clasificación, se consiguió identificar que al grupo de adultos mayores sanos pertenecen un 2 %, al de enfermos un 16 %, 28 % corresponde al de mayores frágiles y, por último, un 54 % está conformado por pacientes geriátricos.

La clasificación conseguida ayuda a prevenir lesiones y mejorar la evaluación, tratamiento, actividades recreacionales, aseo y alimentación, así como a disminuir las limitaciones socioculturales (que son un limitante). Gracias al estudio descriptivo, analítico y transversal de un grupo específico de adultos mayores se cumple el propósito de describir, caracterizar, interpretar y analizar los datos de forma cuantitativa, donde se fundamentan los aspectos de clasificación de 50 adultos mayores. Se utilizó una gama de test, índices, pruebas y cuestionarios orientados a proporcionar datos sobre las características clínicas, funcionales cognitivas y sociales del adulto mayor.
Variación anatómica alta de la arteria braquial en piezas morfológicas. Anfiteatro Universidad Privada del Valle Cochabamba
Authors: Torrejon Carmen , Pary José Miguel
Published: April 2023

Durante la disección de Anatomía Humana se observaron frecuentemente variaciones en el origen de troncos arteriales importantes en las extremidades superiores, como es el caso de la división alta de la arteria braquial, descrita por diversos autores clásicos y contemporáneos. Se realizó un trabajo de investigación de tipo descriptivo y observacional donde se estudiaron 63 miembros superiores disecados en los depósitos de piezas anatómicas del Anfiteatro de la Universidad Privada del Valle. Se procedió a la observación de piezas con registro y procesamiento de los datos, con lo que se determinó que 4 (6,34 %) de las 63 piezas observadas corresponden a variaciones en la división alta de la arteria braquial; en 3 de ellas se observó que la división se produce en la unión del tercio superior con el tercio medio del brazo y en 1 caso se producía en el tercio medio del brazo al comparar este resultado con lo descrito en el tratado de Anatomía Humana de Testut, con un porcentaje casi coincidente. En un estudio similar realizado en la ciudad de La Paz por el Dr. Alvarez, se encontraron 4 casos en más de 200 cadáveres, siendo entonces esta variante menos frecuente. Es importante tomar en cuenta la presencia de variaciones arteriales al planificar intervenciones en extremidades superiores, pues conocerlas evita lesiones de la red capilar; por ello, se sugiere sistematizar el registro de variaciones anatómicas, ya que es importante resaltar en el ámbito educativo la observación sistematizada, para así formar criterio clínico en el futuro profesional en salud.

Published: April 2023

Los cuerpos sin vida siempre adoptan una posición final. En este artículo se describen las distintas posiciones cadavéricas, para lo que se toma como base el plano horizontal del cuerpo (denominándose decúbito), dando lugar a las siguientes variantes: dorsal, ventral o prono, lateral derecho, lateral izquierdo, posición en rana, posición genu/pectoral, posición sedente, la suspensión completa, suspensión incompleta, sumersión completa, sumersión incompleta, de roser o proetz, de boxeador, tónico-cervical asimétrico, fetal y de depage. Según la posición de las extremidades tenemos: brazos en extensión, brazos en aducción, brazos en flexión, piernas en extensión, piernas en abducción y piernas en flexión. Las posiciones en la que un cadáver se puede encontrar por motivo de la posible comisión de un hecho delictuoso ayudan a determinar la probable dinámica de la muerte, ya que las posiciones cadavéricas son proclives a diferentes tipos de hechos como ser un homicidio, suicidio o que el sujeto haya sufrido un accidente (ya sea por descuido o provocado por algún tercero). La posición del cadáver ambién es importante para determinar si el cadáver fue movido de posición y/o lugar, por lo cual el médico forense debería participar en el levantamiento del cadáver.
Estudio de las variaciones morfológicas del círculo arterial del cerebro con inyección de silicona roja, anfiteatro de Universidad Privada del Valle (2015-2017)
Authors: Escobar Chavarría Hernán Severo , Escobar Romero Jaime
Published: April 2023

El conocimiento preciso de la anatomía cerebral es fundamental en la formación y la práctica de la neuroanatomía de los estudiantes que cursan la materia de neurología y neurocirugía. Actualmente, el estudio de la anatomía humana ha cambiado su enfoque, de ser una anatomía descriptiva y de disección a una con aplicación clínica. El presente estudio fue realizado con el objetivo de conocer las variantes morfológicas que presenta el círculo arterial o polígono de Willis, en encéfalos encontrados en el Anfiteatro de la Universidad Privada del Valle. Para ello se prepararon 19 encéfalos extraídos de cadáveres, inyectándose silicona roja acética modificada en las arterias que irrigan el cerebro, observándose el trayecto que tienen los vasos sanguíneos. Una vez solidificada la silicona, se realizaron mediciones del diámetro externo de cada arteria o vaso sanguíneo, con la ayuda de un calibrador digital. Los resultados encontrados revelan que el diámetro externo de las arterias cerebrales es superior en un 68,42% a 1,00 mm y en las arterias cerebrales comunicantes el tamaño es superior a 0,5 mm (en ambos casos estos son considerados de tipo clásico). El 31,58% presenta variantes anatómicas de tipo hipoplásico, única anomalía encontrada, predominando la hipoplasia unilateral en el lado izquierdo. Su conocimiento ayuda a predecir que los que tienen un círculo arterial normal o clásico presentan un daño cerebrovascular y su recuperación es mejor en relación con los que tienen hipoplasia o alguna variante anatómica. El pronóstico es que tendrá mayores complicaciones respecto al clásico.

Published: April 2023

La Diabetes Mellitus tipo 2 es una enfermedad crónica degenerativa que implica una alteración del metabolismo, la cual se caracteriza por una secreción deficiente de insulina o alteración de sus receptores, que ocasionan cambios negativos en los procesos metabólicos del paciente. Se realizó un estudio descriptivo, no experimental, transversal con el objetivo de describir los estilos de vida en pacientes con Diabetes Mellitus tipo 2 del Centro de Salud Piedra Liza en el año 2018. Se incluyó a 67 pacientes entre 26 y 72 años, de sexo femenino y masculino, diagnosticados con Diabetes Mellitus tipo 2 del Centro de Salud Piedra Liza, Rímac (Lima - Perú).

Se utilizó el instrumento IMEVID (Instrumento para Medir el Estilo de Vida en Diabéticos), el cual consta 25 preguntas con posibles puntajes de 0,2 y 4 a las tres opciones de respuesta, correspondiendo el puntaje más alto a la conducta deseable. Los resultados encontrados indican que los pacientes presentan estilos de vida poco adecuados en cuanto a su nutrición, actividad física, consumo de bebidas alcohólicas, información sobre su enfermedad, emociones y adherencia al tratamiento médico, pero un estilo de vida saludable en cuanto al hábito de fumar por su baja incidencia. Se concluyó que los estilos de vida que presentan los pacientes con Diabetes Mellitus tipo 2 del Centro de Salud Piedra Liza son, en su mayoría, poco saludables.

La valoración de las lesiones en medicina forense se asocia al delito en lesiones personales, las cuales requieren un examen de peritaje para su valoración del daño e incapacidad. Este examen de lesiones es sumamente importante en casos de violencia familiar, maltrato y abandono de menores, casos de tortura, delitos contra la libertad, integridad sexual, genocidios e incluso investigaciones de homicidios.

La lesión es una alteración de la morfología y/o fisiológica de órganos y sistemas o segmentos corporales, producidas por un agente traumático. El médico forense debe identificar, describir, y localizar las alteraciones morfológicas y funcionales evaluadas para ayudar a confirmar o descartar las diversas hipótesis sobre los hechos. Para la evidencia física es importante considerar el Principio del Intercambio de Locard: "Siempre que dos objetos entran en contacto estos transfieren parte del material que incorporan al otro objeto". Durante la inspección se debe ser extremadamente cuidadoso, ya que la evidencia puede ser ignorada o no vista.

En los ultimos afios las controversias sobre las vacunas han ganado territorio a nivel internacional, donde se ha visto el aumento de rechazo por parte de los padres a vacunar a sus hijos. Entre la polémica mas resaltante es el efecto del timerosal, el cual se busca prohibir como preservante en las vacunas, por su posible vinculacion con el autismo. Los padres "antivacunas", generalmente, se centran en rechazar esta medida porque distintos medios de comunicacion tienden a difundir informacion erronea debido a la falta de comprension sobre la informacion cientifica. Este estudio esta basado en la revision de multiples articulos de revista en su gran mayoria consultados en el portal SciElo. Todos los autores llegaron a una uinica conclusion que concuerda con la nuestra: que las vacunas que poseen timerosal no presentan un riesgo potencialmente nocivo para generar alguna patologia neurologica.

Published: April 2023

The counterfeit medicine supply chain deals with a main issue on safety of drug. During the actual manufacture of drugs, it is a difficult process to trace the accurate pharmaceutical ingredients. Drugs that contain inactive ingredients and that do not contain calculated active ingredients can ultimately lead to harming the end consumer and also death of end consumer. Blockchain’s technology has the capability to completely trace the drugs, from manufacturer to end consumer, and provides the basis to identify counterfeit-drug. This paper aims to address the issue of drug safety using Blockchain and encrypted security. The methods used are SHA algorithm, AES Rijndael algorithm, Blockchain TCP Remoting concepts.

Published: April 2023

Because of its relevance in the growth of tremendous applications in the medical area, data mining is a hugely important domain for exploration. When it comes to fatalities throughout the world, heart disease appears to be the leading cause of death. Recognizing a person’s risk of heart disease, it is a difficult assignment for health professionals since it takes very much time and extensive medical testing in the existing models. For the early prediction of cardiac disease, an improved version of the K-Nearest Neighbors (KNN) and Decision Tree (DT) classifier are applied, which ensures greater accuracy than existing models. Enhanced KNN is used for the correct treatment of patients and preserve consistency in the heart disease prediction system. We have calculated feature relevance, which assigns a score to independent factors based on how well they predict the difference walking. The variables difference walking, stroke and diabetes were the most relevant aspects, as shown in figure 2. We have compared to other existing models, the proposed model outperforms the existing models in terms of heart disease prediction. And the suggested work’s KNN algorithm hasthe greatest accuracy of 90.97 percentage and the highest ROC Curve of 69.97 percentage in predicting heart disease in comparison to Decision Tree (DT). The expenses and duration of treatment are reduced when the condition is detected early.

Published: April 2023

Bir sosyal medya aracı olarak Twitter, kamusal halkla ilişkiler sürecini daha etkili ve denetlenebilir hale getirmektedir. Kamusal halkla ilişkilerde, kurumların hedef kitleleriyle Twitter üzerinden geniş çaplı iletişim kurabildikleri görülmektedir. Bunun yanında, Twitter’da hedef kitlenin de kendi içeriğini oluşturabilmesi, kamu kuruluşlarının mesajlarına tepki verebilmesi olağan hale gelmiş, kendilerini ilgilendiren olumlu veya olumsuz herhangi bir durumda kamuoyu oluşturarak gündem belirleyebilmeleri imkanı doğmuştur. Bu çalışma kapsamında Milli Eğitim Bakanlığı’nın Öğretmenlik Meslek Kanunu çalışmaları esnasında öğretmenlikte kariyer basamakları uygulamasının hedef kitleye nasıl yansıdığı araştırılmaktadır. Bu çalışmanın birincil hedef kitlesi konumundaki öğretmenlerin Twitter platformundaki tepkileri, duygu analiziyle araştırılmış ve elde edilen veriler sunulmuştur. Araştırma kapsamında, Öğretmenlik Meslek Kanunu çalışmalarının yürütüldüğü zaman aralığı, 1 Aralık 2021 – 24 Kasım 2022 tarihlerini kapsayan dört dönem olarak ele alınmıştır. Çalışmada kullanılan veri seti, Twitter API ile dört döneme ayrılan ve her dönemden 2500’er tane rastgele çekilen ancak ilgili kanuna ilişkin birtakım etiketlerle sınırlandırılan toplam 10.000 tweetten oluşmaktadır. Verilerin toplanması, kaydedilmesi, işlenmesi, analiz edilmesi ve görselleştirilmesi sürecinde Orange programı kullanılmıştır. Çalışma sonucunda, Twitter’ın kamusal halkla ilişkilerdeki önemi ve veri işlemenin kamusal halkla ilişkiler politikalarının şekillenmesindeki etkin rolü açıkça görülmüştür.

W kierunku konceptualizacji sprawiedliwości społecznej w przestrzeni wiejskiej Ukrainy
Authors: Borodina Olena
Published: April 2023

W przedstawionym artykule podjęto kwestie sprawiedliwości społecznej i sprawiedliwości przestrzennej, przywołano genezę tych pojęć i omówiono ich dialektykę oraz rolę odgrywaną przez nie w kształtowaniu polityk rozwoju regionalnego i obszarów wiejskich. Sprecyzowano, że społeczność jest przestrzennie sprawiedliwa, gdy wszystkie jej części respektują prawa poszczególnych członków. Rozwój obszarów wiejskich uwzględniający sprawiedliwość społeczną i przestrzenną powinien wiązać się z poszanowaniem podstawowych praw człowieka, promować inkluzywne działania na tych terenach ukierunkowane na zmniejszenie nierówności gospodarczych i polaryzacji społecznej, które są wynikiem neoliberalnych przemian. Odnosząc się do specyfiki ukraińskiej reformy samorządowej, podjęto próbę określenia obszarów kształtowania (nie)sprawiedliwości, co ma umożliwić dalsze opracowywanie mechanizmów wyrównywania procesów rozwoju lokalnego.

Published: April 2023

An experiment was carried out to investigate the effect of 15 tha-1 of each of green cane top (GCT), filter mud (FM) and bagasse (BA)and their combinations, on ratoon cane, sugar yield and ratoon yieldrecovery at Assalaya Sugar Scheme. The amendments were verticallymulched, in furrows, in a salt-affected clay soil. Plant cane crop washarvested in Dec. 2004/05 and Dec. 2005/06 and ratooned in seasons2005/06 and 2006/07, respectively. The treatments were arranged in arandomized complete block design, replicated four times. The treated soilgave significantly higher cane, sugar yield and ratoon yield recovery thanthe control. The different combinations of any two of the threeamendments had a significantly higher cane and sugar yields than that ofany single one. GCT + BA resulted in the highest cane yield (117.5),followed by FM + BA (116.7) and then GCT + FM (115.9 t ha-1 ); butwith no significant differences between them. The ratoon yield recoveryof the treated soil was significantly higher than the control. BA showedratoon yield recovery of 94.0 % in 2004/05 and 97.0 % in 2005/06.Whenever there was BA in a treatment, the ratoon yield recovery washigher. Although GCT had lower ratoon recovery percentage, it producedthe highest sugar tonnage. For high cane, sugar yield and ratoon yieldrecovery, 15 t ha-1 of each of GCT and BA are recommended.
Calculation of K Uptake by Three Crops Grown Under Controlled Conditions Using a Mechanistic Model
Authors: El Dessougi Hanadi I.
Published: April 2023

The aim of this study was to compare simulated and actual Kuptake by three crops, under different K concentrations in the soilsolution, in order to try to explain the underlying mechanisms of nutrientuptake by these crops. In 2002, wheat (Triticum aestivum L. cv. Star),barley (Hordeum vulgare L. cv. Madras) and sugar beet (Beta vulgaris L.cv. C+ T) were grown on a sandy clay loam, with various Kconcentrations in soil solution, in the growth chamber at the Institute ofAgricultural Chemistry, University of Goettingen, Germany. Data werecollected on K transport in soil and uptake by the three crops and used forsimulation by a mechanistic model which encompasses uptake by roothairs as well. To quantify the significance of single soil and plantparameters for nutrient uptake, a sensitivity analysis was carried out.Under sufficient K in the soil solution, where transport was not limitinguptake, the model predicted the actual K uptake correctly. At deficient Kconcentrations, the model over-predicted the K uptake by both wheat andbarley but under-predicted that of sugar beet. The calculatedconcentration profiles around the roots showed that for cereals wrongvalues of the uptake kinetics caused the over-prediction of K uptake,whereas for sugar beet some processes more than was considered by themodel took place.

Published: April 2023

The objective of this study was to investigate compositionalchanges during ripening of ‘Baladi’, ‘Ekostika I’ and ‘Ekostika II’papaya fruit cultivars at 20 ±1 ⁰C and 85% - 90% relative humidity. Thefruits of the three cultivars exhibited a typical climacteric pattern ofrespiration with peak of respiration of 82, 92 and 98 mg CO 2 / kg-hr,reached after 10 days in the three cultivars, respectively. Weight loss,total soluble solids (TSS), total sugars and ascorbic acid contentprogressively increased during ripening of the three papaya cultivars.More increase in TSS and total sugars was observed after the climactericpeak of respiration. Fruit tissue firmness and total phenolic compoundsdecreased continuously during ripening in the three cultivars. Reducingsugars, total protein and titratable acidity steadily increased to reach apeak, which coincided with the climacteric peak of respiration, andsubsequently decreased afterwards. The local ‘Baladi’ cultivar had alower respiration rate, more firm and less weight loss during ripening,which may indicate a longer shelf-life than the other two introducedcultivars. On the other hand, the introduced cultivars were higher inTSS, total and reducing sugars and ascorbic acid content and lower intitratable acidity and phenolic compounds, which may reflect a bettereating quality.

Striga hermonthica (Del) Benth is a semi-parasitic weed thatreduces yields of sorghum, maize, pearl millet, sugarcane and rice in thesemi-arid tropics. Germination of striga seed is induced by stimulantsexuded by roots of host and non-host plants. The objectives of this studywere to compare the ability of some host and non-host crops to inducestriga seed germination and haustoria formation as well as to confirm thesusceptibility of wheat and barley to infestation. S. hermonthica seedswere collected from Abu Haraz, Gezira State, Sudan, in 2004/2005, andtheir germination on some host and non-host crops was investigated usingroot chambers that allow observation of striga underground stages. Strigaseeds germinated with all tested crops. Besides sorghum varieties andmaize, S. hermonthica germinated, attached and developed to completestriga plants with barley and two cultivars of wheat from Sudan. This isthe first report of S. hermonthica parasitizing wheat and barley in Sudan.Use of root chambers proved that some leguminous crops weresusceptible to S. hermonthica. Chick pea (Cicer arietinum L.),phillipesera (Vigna trilobata L.), brown seed cowpea [Vigna unguiculata(L.) Walp.], hyacinth bean (Lablab purpureus L.), peas (Pisum sativumL.) pigeon pea (Cajanus cajan L.), faba bean and mung bean inducedseed germination, attachment and development of complete green strigaplants. Soybean, roselle, safflower and sunflower supported germinationand attachment of S. hermonthica, but there was no further developmentof the semi-parasitic weed.

Published: April 2023

The effect of modification of some selected MS nutrientmedium on in vitro growth and development of papaya (Carica papayaL.) shoot tips was examined with the objective of optimizing shootregeneration and rooting efficiencies. Modifications were made onselected components of MS medium. Shoot tip explants were obtainedfrom in vitro-grown plantlets. The results showed that MS salts at thetwice full strength was optimal for all parameters measured comparedwith other strengths tested. Sucrose concentrations of 0.75% and 1.5%were better than the other concentrations tested for growth anddevelopment of cultured shoot tips, and there was no significantdifference between them. The results revealed the importance of inclusionof BA and NAA in the nutrient medium at relatively low concentrations,the best results for shoot and leaf formation was recorded with thecombination of BA at 1.0 mg /litre and NAA at 0.01mg /litre, where thegreatest number of shoots and leaves was obtained. The combinationtreatment of 0.3 mg/litre BA and 0.00 mg/litre NAA recorded the bestresults for mean shoot elongation, compared with the other combinationtreatments tested. However, the produced roots were morphologicallyabnormal. The study attested to the essentiality of IBA for rooting of invitro produced papaya shoots, and the data suggested the conduction ofadditional studies for determination of optimal concentration for rooting

Published: April 2023

A feeding trial was carried out to study the effects of sorghumtannin on the performance and carcass characteristics of broiler chicks.Seven experimental diets were formulated using zero tannin maize ascontrol and six sorghum grain varieties, each two with low, medium andhigh tannin level. Diets were fed to 196 unsexed Hubbard commercialbroilers chicks for 5 weeks. Low tannin Safra had the best amino acidscomposition followed by high tannin sorghum varieties. Broilersperformance and carcass characteristics showed inconsistent trend as thelevel of tannin increased, since the birds consuming sorghums with hightannin content gave better performance than their counterparts fedmedium tannin. In addition, the results showed that sorghum varietieswith the same tannin level gave different effects on broiler performanceand carcass characteristics. These results indicate that, tannin level maynot be the sole factor affecting nutritional quality of sorghum grains; otherfactors may be involved.

An experiment was conducted to study the effect of feedwithdrawal at different ages during the hottest summer days on thegrowth performance and some carcass traits of broiler chicken. Onehundred thirty five male chicks at 14 days of age (DOA) with averagebody weight (375 g/bird) were randomly allotted to three treatments withthree replicates each. The treatments consisted of the control (no feedwithdrawal), early feed withdrawal (EFW) at the fourth week of age andlate feed withdrawal (LFW) at the fifth week of age. The treatments wereassigned to a completely randomized design. The experiment lasted forfive weeks having one week as a transitional period, and it was terminatedat 49 DOA. The feed withdrawal duration was two weeks for each group.Feed withdrawal was undertaken from 10:00 am till 7:00 pm. Feed intakeand live body weight were recorded weekly. Feed conversion ratio (FCR)and the cumulative mortality rate were calculated. Some physical andchemical analyses were carried out for some carcass parts (drumstick andthigh). The abdominal fat pad (AFP) was removed and weighed. TheLFW group significantly (P ≤ 0.05) consumed the highest amount of feed,whereas the EFW group consumed the least amount. The cumulativemortality rate was significantly (P ≤ 0.05) lower for LFW and EFW, andthe control group recorded the highest rate. At 49 DOA, live body weightwas significantly (P ≤ 0.05) the highest for the LFW group, whereas theother groups recorded similar body weights. The overall FCR wassignificantly (P ≤ 0.05) the best for LFW group, whereas the control had
