Humanistyczna odpowiedzialność przedsiębiorstwa
Authors: Mazur Barbara
Published: February 2025

The modern world expects socially responsible activities from business. The results of such activities
determine the social effectiveness of business. It is expressed by the application by enterprises of
principles, policies and practices related to the concept of Corporate Social Responsibility (CSR).
CSR at the manager level, which is the subject of the analysis in this monograph, is associated with
the recognition that managers have free choice in making decisions. They can use it to fulfill the
company’s social obligations and achieve socially responsible results. These results depend on
managers’ application of humanistic principles in human resources management.
Considering the importance and topicality of issues related to the social involvement of
enterprises, the aim of this study was to identify the opportunities inherent in CSR activities at
the level of managerial discretion. It has been proven that managerial discretion combined with
a humanistic management style leads to the development of humanistic business responsibility.
To highlight the humanistic approach to business, it was compared with the economic approach.
Thus, presenting the fundamental differences in their assumptions as to the essence of man, and
pointing to the differences in the values recognized in both paradigms as well as the organizational
cultures created within them.
Management based on the economic paradigm sees the essence of man in the concept of
homo economicus, which is a guarantor of the rational economy of human activities. In humanistic
management, the concept of zoon politikon is applied, referring to the definition of man as a being
striving for full and active participation in social life. Values characteristic of humanistic management are interpersonal and moral values, while values characteristic of economic management
are intrapersonal and competence-based. Both paradigms create organizational cultures with
different orientations. The perception a human being, the preferences of values, and the resulting
orientations of organizational cultures influence the results of discretionary actions of managers
in the sphere of CSR. These, in turn, affect social effectiveness of those organizations.
The contents of this monograph link the issues of CSR with the humanistic trend in management. This monograph can be helpful in seeking answers to the question of what should be
changed in the way of thinking about management to make it more economically and socially
effective. The monograph indicates one of the possible ways to achieve this goal – by applying
the concept of humanistic corporate responsibility implemented at the individual CSR level in
managerial practice.

Mangrove ecosystems play a crucial role in maintaining the ecological balance of coastal areas, including protection against abrasion, providing habitat for marine species, and acting as a carbon sink. This study aims to identify indicator species and analyze biodiversity in Darunu Mangrove Park, Darunu Village, Wori Subdistrict, North Minahasa Regency. The research was conducted over three months (May–July 2024) using a line transect method for vegetation data collection. The results show that three dominant mangrove species were identified: Rhizophora apiculata, Rhizophora mucronata, and Sonneratia alba. R. mucronata exhibited significant dominance, both in terms of mature trees and saplings, and had the highest Important Value Index (IVI). The mangrove species diversity in this area is classified as low, with the. Diversity Index (H’) indicates an imbalance in the ecosystem's species composition. The Dominance Index (C) and Evenness Index (E) analyses indicate strong dominance by certain species, particularly R. mucronata. This study recommends the importance of enhanced monitoring and more intensive conservation efforts, including the replanting of threatened mangrove species and raising community awareness of mangrove ecosystem conservation.
Keywords: Darunu Mangrove Park, Diversity, Indicator Species, Important Value Index.

Published: February 2025

Regions become an important arena in recognizing the rights of indigenous peoples. The authority of regions to recognize indigenous peoples has strengthened along with the decentralization that was rolled out after the New Order regime through Law Number 22 of 1999 concerning Regional Government. The spirit of regional autonomy is in line with the hopes of indigenous peoples throughout the archipelago to once again voice the importance of recognizing the rights of indigenous peoples who for a long time have experienced various denials of their identity as part of the Unitary State of the Republic of Indonesia. In such an atmosphere, the government responded to the demands of indigenous legal communities by giving authority to regional governments to determine the existence and rights of indigenous peoples. The research method used in this journal is a literature review method and uses a normative juridical and qualitative approach. This literature research method is used to examine the political protection of the formation of laws and regulations for Indigenous People’s by exploring concepts, regulations and implementation through relevant materials. A normative juridical approach is used to analyze legal aspect, while a qualitative approach is used to analyze the views and perceptions regarding the recognition and protection of indigenous people’s rights in Seluma Regency. Post-reform, the recognition and protection of indigenous peoples has undergone political and legal changes, both in terms of laws and constitutional court decisions. These changes delegate authority to local governments to recognize and protect indigenous peoples. In line with these political and legal changes, the Seluma Regency Government has issued Regional Regulation Number 3 of 2022 concerning Procedures for Recognition and Protection of Indigenous Peoples in Seluma Regency and in September 2024 based on recommendations from the Indigenous Peoples Committee, the Regent of Seluma Regency has issued a Decree concerning the Determination of Recognition and Protection of the Indigenous Communities of Serawai Pasar Seluma, Arang Sapat, Napal Jungur, Lubuk Lagan, and Semidang Sakti Pering Baru.

Goal. Determination of optimal methods of phytosanitary monitoring and strategies for controlling the number of harmful arthropods based on ecologically safe preparations on ornamental crops in urban green areas.
Methods. Monitoring of the phytosanitary state of urbophytocenoses was carried out by the method of route surveys of plantations. The method of visual detection of the phytophagous or traces of its vital activity on the trunk, branches, shoots and leaves was used to examine the crown of plants. To record the density of phytophagous colonies and to identify species, individuals were collected using a transparent adhesive film. Colored glue traps were used to monitor Lepidoptera, Diptera, Coleoptera and other insects.
Results. The use of colored glue traps in the closed soil of the Botanical Garden named after Acad. O.V. For the purpose of monitoring insects, Fomina made it possible to identify 16 species of phytophages from 4 orders: aphids (Aphidoidea) Myzus persicae Sulz., Macrosiphum rosae L., Idiopterus nephrolepidis Davis.; coccids (Coccoinea) Nipaecoccusnipae Mask, Pseudoccus longispinus (Targioni Tozzetti), Coccus hesperidum L., Diaspis boisduvalii Sign., Kuwanaspis pseudoleucaspis Kuw.; whiteflies (Aleyrodoidea): Aleurodes vaporariorum Westw., Bemisia tabaci Genn., B. argentifolii Bellows; thrips (Thysanoptera): Thrips tabaci Lind., Heliothrips haemorrhoidalis Bouche., Frankliniella occidentalis Pergande, Echinothrips americanus Morgan, Thrips palmi Karny. Among the seven colors we used to determine the degree of attractiveness of insects that are common in indoor soil, the most attractive color is yellow. Using color traps in open ground to monitor species such as Phyllonorycter issikii Kumata (a plant pest of Tilia L.) and Cameraria ohridella Deschka & Dimic (a plant pest of Aesculus L.) showed that three colors were most attractive to these species: blue, green and red. A high level of effectiveness of the drug Phytocomplexon-1 has been established in comparison with other options. For the pests Quadraspidiotus perniciosus, Hyphantria cunea and Cydalima perspectalis, this drug showed the highest efficacy rates ranging from 79.5 to 92.4%.
Conclusions. The use of colored glue traps in closed and open ground conditions is an important element for insect monitoring. It is important to consider the color of traps when planning strategies for monitoring and controlling plant pests, which can improve the effectiveness of plant protection measures. The high level of effectiveness of new environmentally safe preparations based on rapeseed oil and plant extracts against various types of harmful organisms has been confirmed. In particular, the drug Phytocomplexon-1 proved to be the most effective for insects. The study indicates the prospects of using environmentally safe methods of plant protection in botanical gardens and megacities.

Inductive power transfer systems are nowadays integrated in more and more electromagnetic devices. A potential application of such systems is the wireless charging of autonomous/semi-autonomous drone batteries, these aerial vehicles being used in the last decade for a lot of domestic or military applications. The operating range of these vehicles is limited because their batteries are limited in size, weight and stored energy. Thus, the drone batteries should be charged more often. Wireless charging stations (Wireless Charging System - WCS) spread over a defined operating region can be used for this purpose once the drones are equipped with intelligent algorithms capable of optimally choosing the closest charging support, based on specific parameters such as: the programmed route, the drone position, the battery charge status, WCS locations, weather conditions, etc.
WCS are more flexible and less sensitive to weather conditions (rain, mud, dust, wind, etc.) than classic plug-in charging systems. However, a good alignment of the transmitter and receiver coils of a WCS remains a challenging aspect in harsh weather conditions (strong wind or storm), solving this problem being essential for an efficient charging process.
The solution analyzed in this paper is a WCS for drones capable of operating in difficult weather conditions. The proposed system is able to automatically center the transmitter (Tx) and receiver (Rx) coils and efficiently lock and release the drone using an electromagnetic system. The Tx coil is mounted on a concrete magnetic support, and the Rx coil is mounted on a ferrite plate placed on the underside of the drone. The analysis of the proposed solution and the determination of the characteristics and performances of the proposed system are performed using the Finite Element (FE) method implemented in the professional software package Flux®.

This paper presents the importance and applicability of Dissolved Gas Analysis (DGA) for monitoring the health of power transformers, essential in electrical distribution networks. The reliability of transformers is critical, and DGA represents an effective method for early detection of internal faults by measuring dissolved gases in the insulating oil. Different interpretation techniques, such as the Duval Triangle and Roger methods, are discussed for identifying fault types based on the concentration and ratio of the resulting gases. The paper also explores the limitations of these methods and future perspectives, proposing a multi-method approach based on machine learning algorithms to improve the accuracy and consistency of DGA interpretation.

The present work refers to the realization of some applications of HTS superconductors in alternating current, of significant importance for the protection of electrical networks and, respectively, the transport of electrical energy: fault current limiter and superconducting cable, realized in ICPE-CA within the Applied Superconductivity Laboratory. The fault current limiter is of resistive type and is made with HTS superconducting material of YBCO type in the form of a strip of 6 mm width and 0.11 mm thickness [1]. The experimental model realized was tested for currents of 200 A AC, its operating temperature is -196 ºC, immersed in liquid nitrogen. The operating principle is based on the superconductor exiting, under the influence of fault currents higher than the nominal current IA> IN, from the superconducting state and its transition to the resistive state, at which point the current is bypassed through an alternating circuit [2], thus protecting the primary circuit.
The HTS superconducting cable is designed to transport intense currents (102 – 103 A), presenting very low Joule losses compared to conventional conductors [3]. The cable is made with HTS superconducting material of the YBCO type with a critical temperature of 92 K used in the form of a strip with a width of 12 mm and a thickness of 0.11 mm [1]. The cryogenic cooling of the superconducting material is performed with liquid nitrogen at a temperature of -196 ºC.

This paper presents an experimental analysis by dielectric spectroscopy of the influence of TiO2 nanoparticles on the electrical properties of low-density polyethylene (LDPE), which determines the delay of the aging of the thermally stressed polymer. The results obtained show that both the real part of the complex conductivity and the tangent of the dielectric loss angle of the analyzed LDPE-TiO2 nanocomposite decrease for one month under the action of thermal stresses at 90 °C. At the same time, these properties' values increase immediately after applying thermal stresses on LDPE without nanoparticles.

Apresentamos, neste artigo, resultados de uma pesquisa que objetivou investigar as práticas pedagógicas explicitadas por professores que ensinam Matemática nos anos iniciais do Ensino Fundamental em relação à utilização da tabuada em sala de aula. A pesquisa foi conduzida por meio de uma abordagem qualitativa na modalidade Pesquisa-Formação, utilizando um curso de extensão online como ambiente para produção de dados. Participaram 128 professores que ensinam Matemática nos anos iniciais do Ensino Fundamental de 15 estados brasileiros, que responderam um questionário aplicado via Google Forms. A análise dos dados foi realizada utilizando a Análise de Conteúdo na perspectiva de Bardin (1977) e Rodrigues (2019), as quais nos proporcionou a constituição das seguintes unidades de registro: (i) memorização da tabuada pelos alunos (ii) Compreensão das operações fundamentais; (iii) Produção de significados para a tabuada e (iv) Romper com o Ensino Tradicional. A análise interpretativa foi realizada por meio de um movimento dialógico entre os dados e a literatura especializada que nos permitiu compreender como os professores que ensinam Matemática nos anos iniciais abordam e utilizam a tabuada em suas práticas pedagógicas em sala de aula. Os resultados nos permitem inferir que métodos tradicionais como: memorização, ênfase na decoreba e competições envolvendo a tabuada, ainda estão enraizados nas práticas pedagógicas de professores que ensinam Matemática. Apesar disso, constatamos um movimento crescente dos professores em busca de melhorar seus processos formativos para diversificar as práticas pedagógicas vigentes, proporcionando assim uma ressignificação com o ensino tradicional, e valorização da compreensão e produção de significados da tabuada pelos alunos.
A Comparative Analysis of the Effects of the Agricultural Extension Services among Small-Scale Farmers in Mpulungu District, Zambia
Authors: Tembo Royd , Nanyangwe Veronica
Published: February 2025

In agriculture-oriented economies worldwide, agricultural extension services are influential in the crop productivity of small-scale farmers. In Zambia, despite the provision of extension services to small-scale farmers, some small-scale farmers have not felt their effects. Therefore, this study conducted a comparative analysis of the effects of the agricultural extension services on maize crop productivity of the 147 food security pack beneficiary households and 152 non-beneficiary households using a mixed methods design in the Mpulungu district of Zambia. The results revealed that the food security pack beneficiary and non-beneficiary households knew the extension services provided in the Mpulungu district. However, the extension workers concentrated more on the food security pack beneficiary households than the non-beneficiary households in the provision of extension services because they wanted the programme to succeed. The majority of the non-beneficiary households did not fully benefit from the agricultural extension services provided in Mpulungu district. The programme beneficiary households recorded higher maize crop productivity than the non-beneficiaries suggesting that the extension services had a positive effect. Challenges such as inadequate extension workers, lack of refresher training for extension workers and loss of trust in the extension system affected both groups. However, these challenges affected the non-beneficiary households more than the food security pack beneficiary households. The study concludes that extension services contribute to agricultural crop productivity. Therefore, the study recommends improvement in extension staffing levels, administrative support, in-service refresher training and capacity building of the extension workers. Also, the implementation of a universal extension service targeting strategy for small-scale farmers is recommended.

This research examined practitioners' narratives on understanding play as a learning pedagogy in early childhood mobile units. The national curriculum framework encourages practitioners and teachers in early childhood settings to employ a variety of play pedagogies to stimulate young learners to develop core skills in early childhood learning environments. Underpinned by Vygotsky's sociocultural theory, the article draws from the zone of proximal development and social interaction as significant theoretical concepts to examine practitioners’ understanding of play as a learning pedagogy in early childhood mobile units. A phenomenological within the qualitative research domain was utilised to gather in-depth data on the topic under investigation. The data was collected through semi-structured interviews with twenty practitioners purposively selected to provide their narratives on understanding play as a learning pedagogy in early childhood mobile units. The Atlas.ti software was used to analyse the collected data using a narrative strategy. The findings revealed that the practitioners maintained a high standard of service delivery within the mobile Early Childhood Care and Education unit contexts, which was transformative, high-quality and play-based. This paper contributes to the existing knowledge of delivering high-quality play-based learning pedagogy in early childhood settings.
Exploring Hong Kong student teachers’ perspectives on children’s play and learning

The concepts of learning through play and a play-based curriculum have gained widespread recognition and popularity in the 21st century. However, in Hong Kong (HK), parents, teachers, and other stakeholders still exhibit limited confidence and capacity in applying these notions to the field of early childhood education (ECE). Moreover, how ECE student teachers perceive and understand these concepts remains largely unknown. To address these issues, this research adopted the ecological system theory as a theoretical framework to 1) investigate HK ECE student teachers’ views on implementing a play-based curriculum and 2) understand the associated difficulties they encounter in the HK context. The study employed a mixed-methods approach, including a Play Belief Survey and a qualitative focus group interview. In total, 200 survey responses and 100 minutes of interview data were collected from a group of ECE student teachers from teacher education institutes in HK. The findings revealed a salient contradiction and concern among student teachers, who expressed positive beliefs about a play-based curriculum yet faced insufficient support in terms of its practical implementation in local ECE settings. This finding underscores the need to closely scrutinise a play-based curriculum in terms of the uniqueness of the HK ECE context. In addition, the implications of this research for the wider Asia-Pacific region are discussed.
