Diversidad avifaunística en agroecosistemas de riego y temporal de la cuenca baja del Lago de Cuitzeo, Michoacán
Authors: Herrera Rodríguez Elvis , Salgado Ortiz Javier
Published: October 2022

Las áreas naturales protegidas representan la principal estrategia de conservación de la biodiversidad. Sin embargo, sólo el 12.93% del territorio nacional se encuentra bajo protección legal. En este escenario surge la necesidad de encontrar alternativas para la conservación de la biodiversidad. Los agroecosistemas (ecosistemas bajo manejo antropogénico) pueden ser una alternativa de conservación, debido a su potencial de ser hábitats productivos para algunas especies silvestres. Aunque se ha encontrado que los agroecosistemas pueden albergar una gran riqueza de aves, hay pocos estudios sobre la avifauna en los agroecosistemas de México. En este estudio comparamos la diversidad de la avifauna en dos tipos de agroecosistemas de la cuenca del Lago de Cuitzeo, en Michoacán, para evaluar su importancia en la conservación de las aves de la región. Llevamos a cabo muestreos de aves en áreas de agricultura de riego y temporal, entre febrero de 2009 y febrero de 2010. En 143 puntos de conteo detectamos 99 especies de aves, 64% de las reportadas para la vegetación original del área. Aunque la riqueza de especies fue similar entre agroecosistemas, los sitios con agricultura de riego presentaron mayor abundancia de insectívoros, mientras que la abundancia de granívoros fue mayor en los sitios con agricultura de temporal. Los agroecosistemas con agricultura de riego fueron más diversos que los de temporal. Ambos agroecosistemas comparten 44 especies y tuvieron una similitud de 0.62 (Morisita-Horn). Ya que una buena proporción de aves habita en estos agroecosistemas, consideramos que son importantes para la conservación de las aves de la región.

Authors: Marrón Gerardo , Carmona Roberto , Ayala-Perez Victor , Gutiérrez-Morales Gabriela
Published: October 2022

En 2012, en la Ensenada de La Paz, al sur de la Península de Baja California, del 29 de marzo al 18 de julio, observamos al menos seis individuos de Platalea ajaja, tres adultos y tres subadultos (conteos máximos), y del 29 de abril al 28 de julio dos adultos de Mycteria americana (vistos al mismo tiempo). Estos registros representan el mayor periodo de estadía en la zona para ambas especies. Adicionalmente, el 16 de junio, encontramos 30 adultos y 13 pollos de Leucophaeus atricilla, 70 adultos y 15 pollos de Hydroprogne caspia, y 120 adultos y un pollo de Rynchops niger en unos islotes artificiales dentro de la ensenada. Por último, en Bahía de La Paz, que alberga a la Isla de Espíritu Santo y ésta a Bahía de San Gabriel, localizamos 700 adultos y 600 pollos de Fregata magnificens. Estas observaciones son nuevas para la zona y amplían el intervalo geográfico de anidación de las últimas cuatro especies. Los resultados que describimos evidencian la necesidad de un monitoreo continuo de la estructura de la comunidad aviar de Bahía de La Paz.

Published: October 2022

We report new nesting sites for the Van Rossem’s Gull-billed Tern (Gelochelidon nilotica vanrossemi) at the Agua Dulce and Xola-Paramán lagoons, in the coast of the state of Jalisco, Mexico. We first recorded the nests on 19 June, 2013 and monitored them at two-week intervals until 2 August, 2013. We found eight nests in the Agua Dulce lagoon and 16 in the Xola-Paramán lagoon. These new records expand the known nesting range of the Van Rossem’s Gull-billed Tern along the Pacific coast, from San Diego, California to the state of Colima in Mexico.
Nuevos pájaros en la ciudad de México: primeros registros de Vireo philadelphicus y Zonotrichia leucophrys para el Distrito Federal
Authors: Aguilar-Gómez Miguel Ángel , Calderón-Parra Rafael , Ortega-Álvarez Rubén
Published: October 2022

El Distrito Federal (DF) es la entidad más pequeña de México; en ella contrasta la presencia de un elevado desarrollo urbano y una compleja variedad de ecosistemas naturales. Tanto en la periferia como en el interior de la Zona Metropolitana de la ciudad de México, las áreas verdes proveen de refugios importantes para la vida silvestre. En este trabajo, reportamos dos especies de aves que no habían sido registradas con anterioridad en el DF: el víreo de Filadelfia (Vireo philadelphicus) y el gorrión corona blanca (Zonotrichia leucophrys). Ambas especies son migratorias de invierno en México y se conoce su amplia capacidad de dispersión. Si bien no es posible asociar factores causales de manera definitiva, consideramos que algunos fenómenos que pudieron haber propiciado la presencia inusual de estos individuos en la región son la reducción de sus hábitats invernales, el severo invierno que se vivió en EUA y Canadá en 2013-2014 y la posible presión inducida por fenómenos de cambio climático global. Consideramos que la creciente comunidad de observadores de aves y de usuarios de plataformas como aVerAves permitirán mejorar nuestro conocimiento en torno a las aves de la entidad.
Urban birds in the Sonoran Desert: estimating population density from point counts
Authors: Johnston López Karina , Macías Duarte Alberto , Castillo Gámez Reyna Amanda
Published: October 2022

We conducted bird surveys in Hermosillo, Sonora using distance sampling to characterize detection functions at point-transects for native and non-native urban birds in a desert environment. From March to August 2013 we sampled 240 plots in the city and its surroundings; each plot was visited three times. Our purpose was to provide information for a rapid assessment of bird density in this region by using point counts. We identified 72 species, including six non-native species. Sixteen species had sufficient detections to accurately estimate the parameters of the detection functions. To illustrate the estimation of density from bird count data using our inferred detection functions, we estimated the density of the Eurasian Collared-Dove (Streptopelia decaocto) under two different levels of urbanization: highly urbanized (90-100% of urban impact) and moderately urbanized zones (39-50% of urban impact). Density of S. decaocto in the highly-urbanized and moderately-urbanized zones was 3.97±0.52 and 2.92±0.52 individuals/ha, respectively. By using our detection functions, avian ecologists can efficiently relocate time and effort that is regularly used for the estimation of detection distances, to increase the number of sites surveyed and to collect other relevant ecological information.

El registro de especies en nuevas localidades permite incrementar el conocimiento sobre sus historias de vida, en particular respecto a su distribución geográfica. El chipe azulnegro (Setophaga caerulescens) es una especie migratoria de larga distancia cuyos territorios invernales se encuentran principalmente en la región del Caribe. En México, los registros de Setophaga caerulescens siguen siendo raros en la mayor parte del país. En marzo de 2014 registramos un macho de Setophaga caerulescens en un parque ubicado en el sur del Distrito Federal. Esta observación representa el primer registro en la entidad, el cual aporta un dato importante al conocimiento que en México se tiene sobre las áreas que ocupa la especie en territorios invernales o bien durante su desplazamiento migratorio.
INCARNATION OF MEANING IN A DRAMATIC WORK
Authors:   Russian State University for the Humanities, Podkovyrin Yurii V. ,   Moscow University for Industry and Finance “Synergy”
Published: October 2022

The object of research in the proposed article is the semantic organization of a dramatic work. The subject of the study is the peculiarities of updating the meaning in a dramatic work, due to its generic specifics. The specifics of artistic meaning are described in this article with the concept of incarnation (implementation). At the same time, the article reveals not theological, but aesthetic (based on the works of Bakhtin of the 1920s) and the hermeneutic content of the above concept. The article focuses on identifying the generic features of incarnation of meaning in works of both classical and modern drama. The scientific novelty of the article is determined by the fact that for the first time (through the concept of incarnation) it reveals the generic features of updating the meaning in a dramatic work, namely: 1) emphasis on the process of transition of the meaning of the characters’ being from the mode of possibility to the mode of reality; 2) placing in the center of the world of drama a character who is in a situation of making a choice of his own life meaning from a range of possible options for its implementing; 3) artistic understanding of the characters life as a limited horizon for the implementation of semantic possibilities, as indicated by the specifics of the image of time (as conditional “now”, unfinished present) and space (as limited and visible conditional “here”); 4) in a non-classical drama, the connection of incarnation of meaning with the image of characters throwing “their being at opportunity” (Heidegger) is mainly not in the space of interpersonal communication, but in the spheres of consciousness and/or language

Super-Powerful Flare Phenomenon of the Water Maser in the Protostellar System IRAS 16293-2422
Authors: Volvach Larisa , Volvach Alexandr , Larionov Michail
Published: October 2022

Based on long-term monitoring of the water vapor maser at 22.2 GHz from early 2019 to March 2021, the most powerful flare event in the entire history of observations was recorded in the protostellar system IRAS 16293-2422 at a velocity of about –1.5 km s–1, lasting of about two years. The maser emission came from the largest structure of maser spots, the high density of which created their partial overlap in time. The total number of individual flares of the water maser reached ten. Due to the high detail of the data obtained, recorded at intervals of 1–2 days, new unique results were obtained. The existence of such a complex configuration of emitting maser spots with very similar radial velocities located on the observer’s line of sight was confirmed for the first time. It was possible to establish that the masers of powerful flares were in an un-saturated state due to the cascade pumping of several masers on the observer’s line of sight. New important parameters of water masers have been obtained, and an assumption has been made about their localization in the gas-dust structure IRAS 16293-2422.

Age diversity management in small and medium enterprises from the Poznań poviat – results of the study
Authors:   Poznan University of Technology, Gajowiak Małgorzata
Published: October 2022

Purpose: The main aim of the article is to present the concept of age diversity management and selected results of own research study made on SMEs from the Poznań poviat. The choice of the area of interest results from the fact that over the last several decades, both the population and the labor force are aging. Such a situation may lead to a reduction in the total number of people employed, investments through a decrease in savings and an increase in pressure on the pension system and the state budget. Design/methodology/approach: Fifty SMEs from the Poznań poviat of the Greater Poland voivodeship participated in the study. In addition, enterprises should employ a minimum of 4 people up to 50 and a minimum of 4 over 50 years old. The survey was carried out using the CATI and PAPI methods. Findings: Based on the research, it can be indicated that the vast majority of SMEs in the analyzed area do not have an age management system in place. Moreover, the needs of the older workers are not realized enough by the managers. Research limitations/implications: It would be better to conduct a survey on a bigger research trail in next edition. Practical implications: It is important to encourage enterprises through trainings and co-financing to implement an age management system, in particular when one can observe the demographic changes worldwide. Originality/value: The originality of the work is sought in an attempt to examine whether SMEs from the Poznań poviat take into account needs of older employees and adapt working conditions to them. Accordingly, the article analyzes the answers made by respondents according to four basic spheres of age management process. What is more, it suggests how to improve the issues badly assessed in the survey.

Published: October 2022

Purpose: The main objective of the article is to present the concept of assessing the level of an organization’s utilization of its potential for transformation towards process orientation, using a practical implementation example. Design/methodology/approach: The structure of the research procedure was based on the theoretical assumptions regarding the methodological procedures involving development of a model of process maturity assessment. Such research methods as bibliometric analysis, systematic literature review, participant observation, opinion survey and semi-structured interview were used to achieve the research objectives formulated. Findings: The value of the article entails the combination of quantitative and qualitative methods to determine an organization’s propensity for transition towards higher levels of process maturity. This effect has been achieved using a method of multi-hierarchical process maturity assessment. It has been determined that the organization under examination is at the second level of process maturity, although many of the elements diagnosed show third-level process maturity potential. An authorial research method has been additionally verified, as well as the examined organization’s real and utilized potential has been determined, which constitute the basis for assessing the level of process maturity. Research limitations/implications: inability to fully objectify the research results obtained. Practical implications: The article shows the basis and the method for identifying the examined company’s real and utilized potential of process maturity as well as for determining the level of process maturity, based on which the company’s strategy towards a higher level of process maturity can be formulated. Originality/value: The unique nature of this article lies in the proposed method of multi- hierarchical assessment of an organization’s process maturity. In order to deepen the interpretation of the results obtained from a quantitative study, qualitative research was used. This allows development of a strategy for achievement of higher levels of maturity.

Published: October 2022

Purpose: The development of digital technology is one of the most important factors driving changes in consumer behavior in the 21st century. Today, the sharing economy covers more and more areas of consumers' daily lives. Using online apps to exchange, sell, buy or rent clothes has become one of the most popular ways of consuming fashion around the world. The main objective of this paper is to assess the importance and estimate the impact of the determinants (motives and unpleasant user experience) of providers' engagement in collaborative fashion consumption (CFC). Design/methodology/approach: The study was conducted using an online survey with 420 respondents in Poland – users (providers) of CFC platforms. A confirmatory factor analysis (CFA) and structural equation model (SEM) was performed using AMOS 21.0 version. The conducted research allowed to identify the importance and to determine the influence of examined factors on attitudes toward CFCs and willingness to use CFC apps in the future. Findings: Economic motives did not outperform non-economic motives to participate as a provider in CFC. Pragmatic motives were by far the most important determinants of fashion sharing. Environmental factors are an important reason for providers to participate in CFC but they may not be a direct motivation for CC participation. Social motives recorded the lowest average importance rating in the context of participation in CFC. Unpleasant user experience negatively influence both the attitudes toward using CFC apps and the willingness to use them in the future Research limitations/implications: The research was conducted only on Polish users, so due to cultural differences, the meaning and impact of the motives of using these apps may be different in other countries. Due to the method of sampling and sample size, the results cannot be treated as representative for the population of Polish users of CFC platforms. Future research could include conducting cross-country research and one may attempt to broaden the scope to 414 S. Michalak, P. Bartkowiak, M. Ankiel, T. Olejniczak, M. Stachowiak-Krzyżan include other categories of motives. Future research could also extend the scope of unpleasant user experience with other factors. Practical implications: The results of research on the motives of users' use of CFC apps should be useful for enterprises in the context of designing activities in the field of marketing communication. Originality/value: The paper fills a research gap in the field of research on the determinants of polish providers' engagement in collaborative fashion consumption (CFC).

Purpose: The main aim of this paper is to identify the specificity of socially responsible innovations in retail against the background of sustainable development, and to identify examples of socially responsible innovations implemented by selected retail chains in Poland. In the Author's opinion, they are crucial for the development of a responsible society, but also for a sustainable economy. Design/methodology/approach: The methodology applied in the article refers to the methodological canon of management sciences, including, among others, conceptual- theoretical and empirical research methodology. On their basis a critical analysis of foreign and Polish literature in the field of management science, theory of development and functioning of the retail trade has been carried out. The analyzed cases of retail chains were considered representative due to their strong market position and large contribution to the development of the FMCG market (the so-called "best business practices") – for this purpose, the qualitative research methodology was applied, including a case study. Findings: The analysis conducted in this paper indicates that large retail chains are creating socially responsible innovations, thus having a significant impact on the spread of socially responsible practices. These activities are mainly based on shaping the environmental awareness of employees and customers, increasing the safety and quality of products, reducing carbon dioxide emissions, effective waste management, rational use of natural resources, reducing staff turnover and improving their working conditions. Originality/value: The article presents how the literature on management science describes and explains the essence, specificity, and types of socially responsible innovations against the background of the sustainable development concept. On this solid factual basis, socially responsible innovations implemented by selected retail chains in Poland were identified. This allowed to verify theoretical assumptions related to the development of socially responsible innovations with the actual state of affairs, reflected in the analyzed practices of retail chains.

Moreover a high positive correlation was indicated between the individual relationship quality constructs. Research limitations/implications: The research sample is a limitation. The research was conducted on a sample of 200 innovative enterprises, but only 22.5% declared maintaining relations with scientific and research and development institutions. Practical implications: The article indicates which quality constructs should be paid attention to by representatives of scientific and research institutions in managing relations with enterprises. Originality/value: The article indicates that in some aspects of relationship management, commitment and communication are more important components than trust and satisfaction. Keywords: relations, relations quality, relations quality constructs, enterprise, business environment institutions.
Managing personal finance by robo-advice users during the Covid-19 pandemic and in the post-pademic period. A comparative analysis of Poland and Slovakia
Authors:   Poznan University of Economics and Business, Waliszewski Krzysztof
Published: October 2022

Design/methodology/approach: This article aims to compare the behaviour of Polish and Slovak robo-advice users in the area of personal finance management during the COVID-19 pandemic, as well as their expected saving, expenditure and investment action after the end of the pandemic. An important aspect of the analysis is a comparison of how the respondents use the PFM application for personal finance management. The article was based on a literature analysis, statistical data, as well as our own pioneering empirical study conducted in September 2021 among clients of the Slovak brokerage house Finax in Poland and Slovakia, which was the first entity in Poland to offer a robo-advice service. A number of statistical methods were used to analyze the collected statistical material: Mann-Whitney U Test, Pearson’s Chi-square test, Linear Regression Analysis, Kendall’s tau correlation analysis. Findings: The COVID-19 pandemic did not adversely affect the personal finance of Polish and Slovak robo-advice users and they differed in terms of investment methods during the pandemic as well as their investment plans after the pandemic. Polish and Slovak robo-advice users used spreadsheets plus special banking and non-banking applications to manage their personal finance. Sociodemographic variables did not largely explain how Poles and Slovaks used the application to configure personal finance. During the pandemic, saving was associated with the use of an application to configure personal finance and the awareness of the existence of such an application among both Poles and Slovaks. Research limitations/implications: The conclusions of the study can be used by financial institutions, FinTechs, robo-advisors and PFM application providers for managing the home budget. Originality/value: The novelty of the article is the first comparative study of robo-advice users in Poland and Slovakia on personal finance management during the COVID-19 pandemic and financial plans in the post-pandemic period. Keywords: COVID-19 pandemic, robo-advice, personal finance management, PFM applications.

Purpose: The main aim of the article is to know the information needs of candidates for university courses and indicate the importance of web analytics tools in the university recruitment process. The authors present the recruitment process for data science high study programme that was conducted in the middle of 2021 at one of the biggest universities in eastern Poland. Theoretical background: Digital transformation is an irreversible process today. Data produced by people, things, administration units and business organizations can be the source of valuable information. That transformation causes new possibilities for fast development, but also creates challenges for education processes and professional work. Furthermore, the digital transformation resulted in creating new professions like data science (DS). Because of data volume and its importance DS professionals became one of the most wanted specialists in the 21st century, and therefore many universities try to launch new study programs related to automated data processing and try to get the attention of potential students. Design/methodology/approach: The process was supported with analytics tools Hotjar and Google Analytics. The results presented in the paper base on the analysis of 974 pageviews recorded by Hotjar and activity of 824 page users reported by Google Analytics. Findings: The analysis showed that web analytics tools are very easy to use in the recruitment process, and that gathered data allows for better understanding of candidates' needs and improving the future requirement processes and tools. Results indicated that the most important topics for candidates were study programme and payment. Form the technical point of view the responsiveness of applications used for the recruitment process is crucial because a lot of traffic was generated by both users of desktop computers and mobile devices. The greatest interest in the program was recorded before the holiday months. Originality/value: The research contributes to academia in the field of recruitment. Paper presents the data science high study programme and indicates the importance of web analytics tools in the university recruitment process.

Purpose: is to show judicial reporting in relation to the rule of law. The text focuses on the considerations and analysis of the relativity of judicial reporting to the rule of law as a kind of values and subjective rights of civil society. An additional assumption is to indicate the essence of the issue in an interdisciplinary perspective, drawing attention to its importance, multidimensionality, connection and social significance, leaving room for own research. Design/methodology/approach: The research method used in the article is the analysis of scientific studies, supplemented by the author's observations and experience. The research procedure included a review of Polish and foreign literature, an analysis of legal acts and court decisions, a case study and deductive reasoning. The above text evokes, in the author's opinion, a separate understanding and application, more and more commonly, also by journalists, of the concepts of justice, the rule of law and law. Findings: A high level of influence of judicial reporting on the rule of law has been demonstrated. Great demand for this type of message and its values, which should be implemented by the rule of law – judgments of common courts, to be considered the most desirable form of the system. Social development in the face of values as an interdisciplinary concept in terms of direction and field allows you to maintain what is with what should happen in the future. It is important not only what intentions people have, but also what competences they have and according to what values they operate. The conducted analysis shows that the correctness of the message and the understanding of the meaning of the rule of law in the area of law are important and vice versa. An autocratically governed society can be fully governed by law, the courts can issue judgments and the court rapporteurs publicly present them, which does not necessarily mean that we are dealing with the rule of law and the rule of law. Research limitations/implications: Limitations of the obtained results may result from a limited text sample, small text size. Originality/value: The presented research and conclusions provide practical tips not only to people of science, but above all to average citizens, mainly those who are not aware that the world of values surrounds people, but depends on them, what values they pay attention to and to which he remains indifferent. Man has the freedom to choose what suits him best, but is rarely able to use it rationally and in an appropriate form and time. Among values, man does not have to do anything and can do much. The less complex and understandable the forensic message, the closer to the concept of simple principles of human life and action. Every aspect of judicial reporting contributes to strengthening the rule of law in the spirit of a democratic rule of law. Like the world to the world, there were processes and comments, and what resulted from them socially (...).

Purple passion fruit is a fruit that is widely cultivated in Indonesia for syrup and juice making. Purple passion fruit has a high nutritional value, such as antioxidants. Passion fruit contains vitamin A, vitamin C, β-carotene, flavonoid, and fiber components. However, passion fruit peel is a waste that can not be appropriately facilitated, so it becomes a waste that can pollute the environment. In addition, the passion fruit peel contains flavonoids that can be used as antidiabetic drugs. This study aimed to determine the difference in flavonoid levels in the peel extract of purple passion fruit by using ethanol and ethyl acetate solvents. The total flavonoid test using the AlCl3 method is then read on a UV-Vis spectrophotometer. The results showed total flavonoid levels of passion fruit peel extract with ethanol and ethyl acetate solvents of 15.01 mg QE/g samples and 1.27 mg QE/g extract. The highest total flavonoid levels were obtained in ethanol extract of 15.01 mg QE/g extract.

Oxidation and hydrolysis damage to cooking oil can occur due to repeated use of cooking oil. Adsorption by utilizing eggshells, which contain high calcium carbonate and have a natural pore structure that can improve the quality of used cooking oil. This study aims to determine the physical properties and characteristics of the thermally activated chicken eggshell adsorbent and to determine the ability of the adsorbent to absorb acid and metal cadmium. The steps carried out in this study were the manufacture of adsorbents, quality tests of the adsorbents produced, and testing of adsorbents on used cooking oil samples based on acid numbers and decreasing levels of metal cadmium in the samples. The adsorption process of used cooking oil was carried out with variations in the mass of the adsorbent, namely 5, 7, 9, and 11 grams, and stirring time for 10, 20, 40, and 60 minutes. Based on the results of the study, it was found that the optimum conditions for decreasing the acid number with the use of an adsorbent mass of 11 grams and a stirring time of 60 minutes resulted in an acid number was 0.9974 mg NaOH/g with a decrease in the acid number of 76.54%, while for cadmium metal it decreased by 100% with adsorption capacity of 2.57124 mg/g.
