Housing Preference and Choice of Nigerians: Evidence from the Organised Private Sector Housing
Authors: Adegoke Samson Akinbamide Omobayo
Published: April 2022

The decline of housing as a political priority despite growing demand has made housing choice decision more difficult. This study is an examination of the revealed preference of beneficiaries of organized private sector housing delivery in Nigeria.  The study relied on data collected from sampled estates from two (2) states in each of the six geo – political zones of Nigeria.  These are flats, bungalows, semi – detached and detached houses.  In all, about 58% of all beneficiaries choose flats about 31% choose bungalows 7% choose semi – detached houses and only about 4% of all the beneficiaries choose detached houses. The findings from this study showed that about 89% of all beneficiaries choose flats and bungalows.  The policy implication of the preponderance of flat and bungalow in the housing choice of beneficiaries is that they are the popular, acceptable and affordable typologies of Nigerians.  Therefore, these types of houses should be given priority in funding by National Housing Trust Fund (NHTF).

Theoretical and philosophical aspects of special powers of a political community with regard to counter terrorism security
Authors: Rosicki Remigiusz
Published: April 2022

The material scope of the analysis undertaken in the text covers the issues concerned with the relationship between two goods. Between the good constituted by community security on the one hand, and the good vested in the power to apply special measures falling within necessary defence and the state of higher necessity. The problem of the relationship between two goods, e.g. a conflict between two goods, can be observed in the competition between the common good and the good of the individual. A similar relation can be noted in the process of derogation from the obligations upon the contemporary political community as regards protection of life and other individual rights and freedoms. Special cases of the conflict between goods include the admissibility of the use of force, violence or restriction of individual freedom. Undoubtedly, situations in which individuals or groups are subjected to torture or have their life taken serve as the most extreme examples of violence use by the political community. All kinds of surveillance measures used by state institutions should be reckoned among the examples concerned with interference in individuals’ private lives.

The main purpose of the analysis contained in the text is to present all manner of argumentation concerned with the possibility of applying special measures within or outside the bounds of necessary defence and the state of higher necessity by the political community. In order to elaborate the objective scope of the analysis, the following research questions have been formulated in the text: (1) To what extent is it possible, within the limits of the law and per analogiam to the individual’s adequate actions, for the political community to apply special measures (necessary defence or the state of higher necessity) with the aim of providing security (and in particular counter terrorism security) for itself?, (2) To what extent is it possible, outside the limits of the law and per analogiam to the individual’s adequate actions, for the political community to apply special measures (necessary defence or the state of higher necessity) with the aim of providing security (and in particular counter terrorism security) for itself?

The presented analysis is chiefly an overview of a conceptual character with regard to the presentation of the issues concerned with the relationship between such goods as security and special powers of a political community. For the presentation of the legal aspects of this issue textual, functional and systemic interpretations have been applied. Next to the individual kinds of legal interpretation, in the course of argumentation a theoretical reflection on the law is used. The conceptual approach to the title problem makes use of argumentation per analogiam to appropriate actions by an individual when faced with a direct threat, and specified in the provisions of the Polish criminal law – necessary defence and the state of higher necessity.
Polska pomoc rozwojowa w Republice Mołdawii jako przykład inwestycyjnych działań uzupełniających w państwie niestabilnym
Authors: Sikora-Gaca Małgorzata
Published: April 2022

Polską pomoc rozwojową dla Republiki Mołdawii można określić mianem inwestycyjnych działań uzupełniających. Celem artykułu jest oszacowanie jej wielkości i scharakteryzowanie poszczególnych projektów. Poruszana problematyka dotyczy również sposobu wdrażania środków pomocowych, w tym charakterystyki modeli funkcjonowania projektodawców i systemowego podejścia do poszczególnych grantów. Zakres pola badawczego obejmuje lata 2008–2018, a więc cezurę czasową, dla której zebrano materiał źródłowy. W artykule wykorzystano dwie metody badawcze: analizy statystycznej i analizy formalno-prawnej. Postawiono następujące pytania badawcze: jaki jest szczegółowy zakres wdrażania polskiej pomocy rozwojowej w Mołdawii? Jakie modele funkcjonowania projektodawców w zakresie ODA wykształtowały się w Republice? Jakie typy projektów finansowano w ramach ODA w Mołdawii po 2004 r.? Republika Mołdawii pod względem inwestycyjnym jest terenem specyficznym. Realizowane tu projekty odbiegają od wyobrażenia europejskiego, skoncentrowanego wokół przemysłu 4.0 zmierzającego do wdrażania w gospodarce procesów automatyzacji, robotyzacji i zaawansowanych technologii. Większość grantów wdrażanych na trenie Republiki dotyczy tymczasem podstawowych potrzeb o charakterze politycznym, społecznym i gospodarczym. Ich realizacja jest źródłem postępu we wskazanych trzech obszarach, bowiem w wielu przypadkach skoncentrowana jest na zapewnianiu podstawowych potrzeb życiowych. Jeśli nawet kwoty udzielanej przez Polskę pomocy nie są wysokie, to za decydujący należy uznać sam fakt zrealizowania określonej inwestycji.

Published: April 2022

Zlewnia Różanego Strumienia jest pierwszą stacją bazową Poznań-Morasko, należącą do krajowego Zintegrowanego Monitoringu Środowiska Przyrodniczego, położoną w granicach poznańskiej aglomeracji miejskiej. Taka lokalizacja zlewni badawczej powoduje jej silne narażenie na antropopresję. Badania przedstawione w artykule dotyczą oceny presji na środowisko przyrodnicze wynikającej z planowanych zmian w zakresie rozwoju zabudowy mieszkaniowej i zróżnicowania w obrębie zlewni oraz potencjalnych skutków dla środowiska przyrodniczego. Rezultaty pokazują, że głównym źródłem presji będzie rozbudowa terenów mieszkaniowych. Konsekwencjami będą: redukcja powierzchni biologicznie czynnej oraz emisja zanieczyszczeń. Otrzymane wyniki mogą służyć jako przesłanka do kształtowania monitoringu środowiska przyrodniczego dla instytucji administracyjnych i badawczych.
Verbal and nonverbal disagreement in an ELF academic discussion task
Authors: Liu Chen , McDonough Kim , Trofimovich Pavel , Uludag Pakize
Published: April 2022

Recent English as a Lingua Franca (ELF) studies have examined the linguistic features of disagreements during interactive academic tasks and casual conversations. Fewer studies, however, have explored nonverbal cues of disagreement, and even less is known about how interlocutors perceive disagreements. Therefore, using data from a corpus of ELF interaction, this study examined the verbal features and visual cues used by ELF university students to disagree during an academic discussion task. The disagreement episodes were selected through a content analysis of stimulated recall protocols in which a speaker stated that a disagreement had occurred. Transcripts were analyzed to classify the speaker’s verbal strategies as being mitigated or unmitigated. Video recordings were examined for facial expressions, body movements, and hand gestures. Findings revealed that ELF students used mitigated linguistic strategies, such as hedges, during disagreement while gaze aversion, smiling, and head nods were the most frequent nonverbal cues. The stimulated recall data showed that disagreements were perceived as an opportunity to listen, think, and share different opinions. Implications are discussed in terms of how to interpret features of disagreement in language classrooms.

Photodynamic therapy (PDT) is an approved promising new treatment modality for a variety of cancers. In combination with nanotechnology, PDT offers the lowest rates of side effects and reveals high treatment efficiency. This study aimed to design and develop a new formulation based on zinc oxide containing Manganese (III) Phthalocyanine Chloride (ZnO/MnPcCl NPs) for use in the PDT protocol and investigate its hemocompatibility with human blood. Additionally, the antitumor activity in mice using the Ehrlich solid tumor as an experimental model was examined. They were nonhemolytic and had no harmful effects on partial thromboplastin time and prothrombin time. ZnO/MnPcCl NPs in conjunction with laser (670 nm/0.6 j/cm2 ) had significantly better in vivo anticancer efficacy compared with pristine ZnO/MnPcCl NPs and laser. These findings confirm that ZnO/MnPcCl NPs could serve as an efficient and biocompatible PDT system for anticancer. Also, this study confirms that the combination between PDT and nanotechnology can improve the shortcomings of photodynamic therapy.

VÍAS Y AGENTES DEL MERCURIO EN LA TEMPRANA GLOBALIZACIÓN: LAS MINAS DE IDRIA Y LOS NEGOCIANTES ITALIANOS (ca. 1600-1666)
Authors: San Ruperto Albert Josep
Published: April 2022

En este trabajo estudiamos la importancia del mercurio como producto global y la capacidad de gestión de determinadas compañías de negocios transnacionales que distribuyeron la materia prima desde el centro de Europa hasta las principales plazas de su consumo. Para ello destacamos dos cuestiones clave: explicamos cómo el proceso globalizador del siglo XVII que protagonizaron las redes mercantiles terminó por modificar las vías de exportación del mercurio, y cómo potenciaron las conexiones europeas, pero también generaron problemas al conglomerado ibérico-germánico gestionado por los Habsburgo. Nos aproximamos a la formación, la gestación y el gobierno de las empresas dedicadas a la distribución del mercurio y, finalmente, exploramos las alianzas transnacionales que ensamblaban a los agentes de negocios del norte y del sur de Europa. Esta cuestión renueva las consideraciones historiográficas entorno al fenómeno de integración de los actores económicos en la Europa preindustrial. Trabajamos con diferentes fuentes: contratos privados, correspondencia mercantil y fuentes institucionales de la República de Venecia y de la Monarquía Hispánica.
Gastrointestinal manifestations in hospitalized patients with chronic liver disease and COVID-19

Published: April 2022

Background and aim. Gastrointestinal manifestations in COVID-19 have been frequently acknowledged by clinicians and scientists. However, their clinical significance and potential influence on the disease outcome is not entirely elucidated. In this study we aim to evaluate gastrointestinal involvement, both digestive symptoms and liver-related changes in hospitalized COVID-19 patients in correlation to the presence or absence of underlying liver disease and rate of mortality.

Methods. We performed a retrospective cohort study of COVID-19 patients, consecutively admitted in a hospital from Chisinau, between September 3, 2020 and May 31, 2021. Data on clinical symptoms and laboratory findings were collected from electronic clinical records. The cohort was divided into two groups, with and without pre-existing liver disease. The Fisher exact, Pearson Chi-square tests were used to compare groups.

Results. A total of 1835 patients were included, 108 (5.9%) with pre-existing liver disease and 1727 (94.1%) without this comorbidity. Digestive symptoms were reported by 331(18%) of the patients, diarrhea being the most common symptom 11.8% (217) and being encountered more in patients with underlying chronic liver disease. No statistical difference was identified between the groups in regard to other symptoms, comorbidities and rate of mortality. But patients with chronic liver disease had significant (P < 0.001) lower ferritin, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in comparison with the other group. At admission, 341 (19.2%) had increased aspartate aminotransferase level (AST) and 317 (17.8%) alanine aminotransferase. The enzyme abnormalities were predominantly mild and transitory. Abnormal AST level at admission and during follow up, higher ESR, CRP, ferritin, lactate dehydrogenase (LDH) was found to correlate with higher rates of mortality.

Conclusion. Digestive implications, especially diarrhea in COVID-19 patients is frequent, but do not appear to be associated with mortality. Elevated liver enzymes during hospitalization, age, high ferritin, CRP, LDH might be interpreted as risk factors for mortality in COVID-19 but further studies are needed to address this topic.

Authors:   Institute for Nuclear Research of the National Academy of Sciences of Ukraine, Kyiv, Ukraine, Danevich Fedor
Published: April 2022

Non-accelerator particle physics is a new field of physics that studies the properties of particles without using accelerators. This area has been developing rapidly for the last 20—30 years providing a number of outstanding results, including the discovery of neutrino oscillations caused by the masses of neutrinos, which became the first experimental proof of an effect beyond the Standard Model of particles and interactions. While the results in the field have won five Nobel Prizes over the last twenty years, this area remains almost unnoticed in Ukraine, despite the fact that here several research groups conduct work on the subject and obtain the results of the highest quality.

This paper presents the results of applying a statistic, remote sensing (RS) technology, and 3D (three-dimensional) numerical model to study and assess the situations and the causes of riverbank erosion of Hau river in An Giang province during the period 2010–2019, chronologically and spatially. The results show that the erosion of the Hau river in An Giang province during the period 2010–2019 has steadily and widely occurred both in seasons. There is a significant difference in the Hau river’s bank changing compared with the popular one in the past. The riverbank erosion process has occurred increasingly, with solid intensity, in a complex way, and even more in the dry season. It is identified that the causes of the erosion are from hydrological characteristics, river flow dynamics, the geological structure, soil characteristics, and the form of the riverbed and economic - social activities. The finding is a scientific foundation to resolve the riverbank stabilization.

Backyard poultry plays an important role in livelihoods of Indian farmers. Back yard poultry production besides improving the family nutrition also improves the overall income of households. The present study was conducted to evaluate the production performance, reproduction and economics of Kuroiler poultry in the backyard production system through front line demonstration (FLD) by Krishi Vigyan Kendra, Jaipur-II. Fifteen tribal farm women who were rearing 5-10 local breed bird were selected from villages i.e. Karwas and Paniyala, block Kotputli, district Jaipur were provided with 50 chicks of Kuroiler breed to each farm women. The demonstration was organized at fifteen tribal farm women fields administering participatory approach by providing 750 chicks. 28th day old chicks of Kuroiler variety were supplied to tribal farm women and the performance of birds in terms of age at first egg laying, body weight (4 month of age), egg production (8 month of age) and economic returns were observed. The mean age at first egg laying was observed as 167.4±2.37days, mean body weight gain at 4 month age was 1797±25.62 g and 8 months egg production per hen was 79.27+2.21. In case of economic returns it was found that by rearing a unit of 50 birds a household can generate an income of about Rs. 26954. The B: C ratio of Kuroiler birds was observed 1:2.93 under back yard poultry management. Thus it may be concluded that the performance of Kuroiler was better than local poultry birds reared.
