Rosnące zapotrzebowanie na wytwarzanie elementów stalowych w przemyśle produkcyjnym wymusza szybki rozwój technologii spawania metali. Jedną z nowoczesnych technik spajania jest łączenie elementów za pomocą spawania laserowego, gdzie materiał łączony jest za pomocą skupionej wiązki laserowej. Metoda ta pozwala uzyskać wysoką wydajność procesu, przy utrzymaniu czystości w obszarze spawania oraz wysokiej jakości złączy spawanych. W przeprowadzonych badaniach porównano metodę spawania wiązką laserową (metoda 52) z konwencjonalną metodą spawania TIG (metoda 141), w celu porównania czasu spawania, wpływu temperatury w SWC po spawaniu oraz jakości uzyskanych spoin.

The growing demand for manufacturing steel components in the manufacturing industry is forcing the rapid development of metal welding technology. One of the modern welding techniques is the joining of components using laser welding, where the material is joined using a focused laser beam. This method makes it possible to achieve high process efficiency, while maintaining cleanliness in the welding area and high-quality welded joints. In the conducted research, the laser beam welding method (method 52) was compared with the conventional TIG welding method (method 141), to compare the welding time, the effect of temperature in the HAZ after welding and the quality of the resulting welds.

Purpose: The aim is to present prosumerism of companies as a form of cooperation with consumers, their expectations, perceived benefits and challenges. Project/methodology/approach: The research tool was a survey questionnaire prepared by the author of this paper. The survey was conducted in 2022 among 1000 adults (18 years and older), by a research company, using CAWI method in a consumer panel. Results: The survey results show that consumers engage in various prosumer activities of companies. However, they also expect companies to be proactive in including them in such activities. They are aware of the prosumerism benefits for companies, but also recognize the challenges related to it. Research limitations/practical implications: Research was conducted among only one group of participants in prosumer activities - consumers. It is planned that future research will also include a second group - companies. This will provide insight into the prosumption activities undertaken, their barriers, as well as their benefits and opportunities. In the paper, recommendations are presented for companies to undertake prosumption activities in order to cooperate with consumers and respond to their expectations. Social implications: The importance of prosumption activities for companies, as well as for consumers, is highlighted, which can influence consumers to become more involved in companies’ activities, thus benefiting them more. Originality/value: The paper analyzes the company’s own research findings on the benefits, expectations and problems associated with prosumption practices of companies. Practical recommendations provide valuable guidance for companies planning and implementing prosumer activities aimed at cooperation with consumers.

Purpose: The article aims to understand how agile organizational practices affect customer engagement in the processes of co-creating the offer. It responds to the growing needs of the market, which require companies not only to provide high-quality products, but also to be committed and open to cooperation with customers. Design/methodology/approach: The study uses a quantitative approach, including an extensive survey of 303 companies. The results were statistically analysed, which made it possible to generate a correlation table showing the relationships between individual practices. Findings: Most companies are positive about customer engagement in product/service testing, designing new offerings, and using customer feedback to improve existing products/services. The high correlation rates between different agile practices suggest that the realization of one practice often entails the implementation of others. Research limitations/implications: Limitations of the study include the homogeneity of a sample focused mainly on downstream employees in small and micro enterprises, which may limit the generalization of results. Practical implications: Companies can use the results of surveys to increase customer engagement by implementing real-time feedback systems, intensifying collaboration on new product development, and conducting regular satisfaction surveys. Social implications: Increased customer engagement in value creation processes can lead to greater customer satisfaction and loyalty, which contributes to building lasting relationships and a better brand reputation. Originality/value: The article offers a new perspective on the application of agile practices in the context of customer engagement, showing how customers can be effectively integrated into business processes, which is crucial to increasing the agility of organizations and their long-term success in the market.

Pamiętamy jak w czasie pandemii pojawiły się firmy, które oszukiwały na maseczkach, na płynach dezynfekujących. Układ towarzysko-polityczny zdawał sobie sprawę z przyszłej mglistej odpowiedzialności, która może nadejść lub nie. Potem pojawiła się kolejna okazja na stworzenie monopolu; powstała krajowa grupa spożywcza, której jedynym osiągnięciem był drastyczny wzrost cen cukru. Kombinacja polityki, a konkretnie osób mających wpływ na regulację prawne, i braku skrupułów zwykle skutkuje pojawieniem się obostrzeń mających na celu stworzenie quasi monopolu, na których zarabiają „znajomi królika”. Inaczej było z importem płodów rolnych z Ukrainy. Tam obostrzeniem była blokada portów czarnomorskich. Kraj więc zmuszony był skierować strumień towarów do krajów ościennych, w tym Polski. Co działo się potem każdy pamięta. Do dzisiaj minister rolnictwa nie zdecydował się odtajnić listy firm, które dopuściły się fałszowania dokumentów przewozowych. Zboże techniczne stawało się zbożem konsumpcyjnym. To, co było wysłane jak tranzyt lądowało w polskich hurtowniach spożywczych.

This paper presents a study on predicting stock trends using a dataset consisting of key financial indicators from 300 S&P 500 companies over a decade. Each company is characterized by 58 financial indicators along with their 1-year changes, offering valuable insights into potential trends. The objective is to develop predictive models to accurately forecast trading actions (buy, sell, hold) based on fundamental financial data. Three machine learning models---Random Forest, CatBoost, and XGBoost classifiers---were trained, employing two distinct voting mechanisms. The first voting mechanism was utilized in the competition, while the second was developed post-competition after the test labels were released. Notably, the second model was trained solely on the training data. The results demonstrate that both voting mechanisms effectively capture trends, as reflected by the average error cost measure, evaluated using the provided error cost matrix.

W artykule opisano wady dualistycznego modelu własności mieszkania i zarządzania budynkami wielomieszkaniowymi (kondominium), które pojawiły się w krajach postsocjalistycznych po prywatyzacji i były spowodowane niewłaściwym otoczeniem instytucjonalnym. Przedstawiono również ogólną problematykę stosowania modelu kondominium dla nowoczesnych i dużych kompleksów mieszkaniowych oraz w trudnych sytuacjach braku środków finansowych na remonty budynków. W takich przypadkach zamiast dalszego komplikowania zarządzania wspólnotami mieszkaniowymi uzasadniona jest celowość ich przekształcenia w jednolity model korporacyjny wspólnej własności domu.

EN

The article describes the defects of the dualistic model of home ownership and management of multi-apartment buildings (condominium), which appeared in post-socialist countries after privatization and were caused by an inappropriate institutional environment. However, the general problematic of using the condominium model for modern large residential complexes and in difficult situations of lack of funding for renovation of buildings is also shown. In these cases, instead of further complicating the management of condominiums, the expediency of their transformation into a unitary corporate model of joint home ownership is substantiated.

Współcześnie konsumenci nie chcą być tylko odbiorcami oferty rynkowej, lecz chcą również mieć na nią wpływ, dlatego też firmy muszą zmieniać swoje modele biznesowe na bardziej otwarte, uwzględniające aktywność, zaangażowanie konsumentów. Prosumeryzm odnosi się zatem do działań firm, które są ukierunkowane na współpracę z konsumentami. Prosumpcja, określana jako aktywność konsumentów, przyjmuje różne formy: od wyrażania swoich opinii, dzielenia się swoim doświadczeniem, przez dostosowywanie oferty do własnych potrzeb, po udział w jej tworzeniu. Takie działania prosumpcyjne są korzystne zarówno dla firm, jak i konsumentów. Jednakże wiążą się z nimi także pewne zagrożenia czy też wyzwania dla obu stron. Artykuł zawiera analizę wyników badań, których celem było poznanie: jak badani postrzegają prosumeryzm? Jakie są ich oczekiwania w zakresie współpracy z firmami oraz jakie korzyści i zagrożenia związane z prosumeryzmem dostrzegają? Większość badanych oczekuje włączania ich w działalność firmy w różnych obszarach. Sami też podejmują różne aktywności prosumenckie, koncentrując się bardziej na opiniowaniu oferty rynkowej i jej testowaniu niż aktywnościach wymagających większego zaangażowania, tj. projektowanie czy współtworzenie produktów i usług. Prosumpcja umożliwia konsumentom m.in. dzielenie się swoją wiedzą, pomysłami, dostęp do informacji, na podstawie których mogą podejmować bardziej świadome decyzje, zmniejszając tym samym ryzyko zakupu produktów niezgodnych z oczekiwaniami, również przez możliwość modyfikowania, dopasowywania produktów/usług do własnych potrzeb. Prosumenci mają także możliwość wyróżnienia się przez zgłaszanie własnych propozycji rozwiązań, które mogą być wykorzystane przez innych konsumentów bądź firmy. Badani zwracali uwagę także na uczestniczenie w sieciach konsumenckich, dzięki czemu nie czują się samotni, ale mają poczucie przynależności do grupy osób, które łączą wspólne zainteresowania. Badani oprócz korzyści dostrzegają też pewne zagrożenia związane z prosumeryzmem firm, tj. wykonywanie przez konsumentów pracy bez wynagrodzenia, manipulowanie konsumentami przez stwarzanie pozorów współpracy, a w rzeczywistości nieuwzględnianie ich propozycji, opinii, a tym samym niedocenianie ich pracy przez firmy. Dlatego też firmy powinny tworzyć rozwiązania umożliwiające konsumentom współpracę z nimi, a także zachęcać ich do aktywności i zaangażowania, gdyż dzięki temu mogą przygotować ofertę zgodną z ich oczekiwaniami, a tym samym wzmocnić swoją pozycję na rynku.

Nowadays, consumers do not want to be just recipients of the market offer, but they want to influence it, which is why companies must change their business models to be more open, taking into account the activity and involvement of consumers. Prosumerism therefore refers to the activities of companies that are focused on cooperation with consumers. Prosumption, defined as consumer activity, takes various forms, from expressing one’s opinions, sharing one’s experience, through adapting the offer to one’s own needs, to participating in its creation. Prosumption activities are beneficial for both companies and consumers. However, they also involve certain threats and challenges for both parties.The article contains an analysis of the results of research aimed at finding out how respondents perceive prosumerism? What are their expectations regarding cooperation with companies? and what benefits and threats do they see related to prosumerism? Most respondents expect them to be included in the company’s activities in various areas. They also undertake various prosumer activities themselves, focusing more on giving opinions on the market offer and testing products than on activities requiring greater involvement, such as designing or co-creating products and services. Prosumption enables consumers, among others, to: sharing their knowledge, ideas, access to information based on which they can make more informed decisions, thus reducing the risk of purchasing products that are inconsistent with expectations, also through the ability to modify and adapt products/services to their own needs. Prosumers also have the opportunity to stand out by submitting their own proposals for solutions that can be used by other consumers or companies. The respondents also emphasized participation in consumer networks, thanks to which they do not feel lonely, but have a sense of belonging to a group of people who share common interests. Apart from the benefits, the respondents also notice certain threats related to the prosumerism of companies, i.e. consumers doing work without remuneration, manipulating consumers by creating the appearance of cooperation, but in fact not taking into account their proposals and opinions, and thus underestimating their work by companies. Therefore, companies should create solutions that enable consumers to cooperate with them, as well as encourage them to be active and involved, because thanks to this they can prepare an offer in line with their expectations and thus strengthen their position on the market.

Corporate Social Responsibility (CSR) has been forming very dynamically and intensively for several decades. The rapid development, as well as the relatively large scope of this concept, which is cross-sectionally related to a number of different social disciplines, so far causes a very significant terminological inconsistency. The paper focuses on the relationship between CSR and the financial performance of companies, or on the positive consequences of applying the concept of CSR in business on the example of a selected company Deutsche Telekom AG, which applies CSR in its business and which achieves positive results not only from this point of view, but also from the point of view of company profitability. When analyzing the company from the point of view of the global market, it quantitatively monitors the impact of the measured indicators on the profitability of total assets (ROA) and on net profit, by testing the basic assumptions made on the classical linear regression model. The main goal of the paper was to find out the impact of CSR on the financial results of the parent company Deutsche Telekom AG for the period 2001-2021 and to find the relationship between CSR and economic benefits.

The research examined the effect of shipping company demographic characteristics on cabotage vessel finance and repayment in Nigeria. The Nigerian Maritime Administration and Safety Agency (NIMASA) have been concerned about the inability of the Ship Acquisition and Ship Building Fund (SASBF) beneficiaries to pay back disbursed loans fully, resulting in the suspension of further disbursement of the fund required for the development of Nigerian local content capacity. The Cabotage Act 2003 was intended for local content development of shipping and maritime logistics capacity. The fund realized through a 2% surcharge on cabotage trade has accrued since inception, but no shipowner has benefited from the CVFF loan. The study relied on both primary and secondary data. Data was collected through a well-structured questionnaire. The study utilized a Statistical Product Service Solution (SPSS v. 23) and a one-sample chi-square test as statistical tools for data analysis. The results reveal that demographic characteristics of shipping companies, such as age, number of vessels, number of employees and total annual revenue, significantly influence CVFF loan repayment. Purpose: To identify and analyze the shipping company demographic characteristics which influence cabotage vessel finance and repayment in Nigeria. The findings suggested practical steps for effective CVFF loan disbursement and reliable loan recovery. Methodology: The study utilized Statistical Product Service Solution (SPSS v. 23) and a one-sample chi-square test as statistical tools for data analysis. Results: The demographic characteristics of a shipping company, such as company age in years, number of employees, share capital, number of vessels and shipyards as well as the age of vessels and shipyards has a significant influence on her Character, Capacity, Credibility, Capital, Conditions, Collateral and Creditworthiness of the organization. Theoretical contribution: The research contributed to exploring, understanding, and applying the probability of credit default theory in shipping finance loan repayment. The demographic internal microeconomic organization Character, Capacity, Credibility, Capital, Conditions, Collateral and Creditworthiness significantly affects the ability of CVFF fund beneficiaries to repay the loans. Practical implications: Prospective borrower indigenous maritime operators should be duly and professionally evaluated to ensure sustainable cash flow and revenue projection during and after granting CVFF loans to guarantee complete repayment.

Early identification of potential financial problems is among important companies’ risk management tasks. This paper aims to propose individual and ensemble models based on various types of neural networks. The created models are evaluated based on several quantitative metrics, and the best-proposed models predict the impending financial problems of Slovak companies a year in advance. The precise analysis and cleaning of real data from the financial statements of real Slovak companies result in a data set consisting of the values of nine potential predictors of almost 19 thousand companies. Individual and ensemble models based on MLP and RBF-type neural networks and the Kohonen map are created on the training sample. On the other hand, several metrics quantify the predictive ability of the created models on the test sample. Ensemble models achieved better predictive ability compared to individual models. MLP networks achieved the highest overall accuracy of almost 89 %. However, the non-prosperity of Slovak companies was best identified by RBF networks created by the boosting and bagging technique. The sensitivity of these models is about 87 %. The study found that models based on neural networks can be successfully designed and used to predict financial distress in the Slovak economy.

The article measures the scope of reporting climate-related information by companies considered CSR leaders in Poland. An original tool is employed for that purpose: a climate-related disclosures index. First, a critical comparative analysis was performed of climate-related disclosure initiatives (regulations, guidelines, standards) to pinpoint the key and commonly required disclosures. Next, an original index of climate-related disclosures was designed. It helped compute index values for 20 companies perceived as Poland’s CSR leaders. Non-financial reports available in the public domain were analysed for that purpose. The study showed that virtually all climate-related disclosure initiatives implement, to a greater or lesser extent, the TCFD recommendations, which were also embedded in the developed index covering 18 indicators. The total index value (ranging from 0 to 1) for the analysed companies was 0.51, with a median of 0.42. The index demonstrates that companies named CSR leaders in Poland do not display high awareness of climate change.

Celem artykułu jest ocena zakresu raportowania informacji związanych z klimatem przez przedsiębiorstwa uznawane za liderów CSR w Polsce, dokonana za pomocą autorskiego indeksu ujawnień klimatycznych. Najpierw przeprowadzono krytyczną analizę porównawczą treści inicjatyw ujawnień klimatycznych (regulacji, wytycznych i standardów) w celu zidentyfikowania kluczowych i najczęściej wymaganych ujawnień klimatycznych. Na tej podstawie zbudowano autorski indeks ujawnień klimatycznych, w oparciu o który policzono indeks dla 20 firm uznawanych za liderów CSR w Polsce (w oparciu o analizę treści publicznie dostępnych w Internecie raportów niefinansowych firm). Badania pozwoliły stwierdzić, że praktycznie wszystkie inicjatywy ujawnień klimatycznych w większym bądź mniejszym stopniu implementują wytyczne TCFD, które stały się podstawą autorskiego indeksu ujawnień klimatycznych, obejmującego 18 wskaźników. Całkowita wartość indeksu (przyjmującego wartości od 0 do 1) dla analizowanych firm wyniosła 0.51 przy medianie równej 0.42. Indeks pokazuje, że firmy zaliczane do liderów CSR w Polsce nie charakteryzują się wysoką świadomością w zakresie zmian klimatu.

Industrial reception spaces (IRSs) are receptacles for a large part of the national socioeconomic activity in Morocco. They contribute substantially to sustaining economic growth and national dynamics of industrialization. These areas are increasingly faced with several constraints, notably deficient infrastructure, competitiveness, and compliance with the new environmental legislation. These constraints stem from the proven and potential impacts of CC on both individual industrial units and the IRS as a common space. There is an urgent need to make these spaces environment-friendly and more resilient to current and future climate risks through appropriate methodological approaches, leading to effective climate risk management and implementation of proactive CC adaptation strategies. This was the context in which this study was conducted. As a case study, the industrial area (IA) of Aït Melloul, located near the city of Agadir in Morocco, was based on a participatory approach of climate risk assessment involving a task force representing the main socio-economic and state operators concerned by this IA. This was accomplished by analyzing the risks and vulnerabilities of the IRS and the agri-food units within it. The analysis provides key elements for a future strategy for business sector resilience and energy transition. The new project to requalify Ait Melloul IA would provide an opportunity to incorporate these elements as well as to capitalize on lessons learned from programs at the local level, particularly about energy efficiency and building the adaptive capacity of businesses.

[Context and motivation] More and more often software development projects involve participants of diverse nationalities and languages. Thus, software companies tend to use English as their business language. Moreover, to better prepare for future jobs, students consciously choose university courses in English. [Question/problem] As a result there is an increasing number of software engineers who are working or studying in a language which is not their native language. The question arises whether native language has an effect on the quality of natural language requirements. [Principal ideas/results] From the analysis of the requirements formulated by 44 participants of our empirical study, it follows that native language may have a negative effect on requirements quality, e.g., ambiguity, variability, and grammar issues. Furthermore, different native languages might drive to different quality issues. [Contribution] In order to prevent quality issues, our findings might be used by educators to adjust their materials to cater to different language groups, while practitioners might use them to improve their requirements review process.

Purpose: Trust is an important factor in supporting the management of employee teams. It plays a special role in developing interpersonal relations, leadership, and goal setting. The most important person who stimulates trust is the leader, who takes steps to build organizational trust. The aim of the paper was to identify the role of leadership in stimulating trust between managers and subordinates as an important factor in business development. The following research questions were addressed to achieve this aim: What relationships exist between vertical trust and intra-organizational processes in companies? To what extent do leadership attributes affect building vertical trust? To what extent do leadership attributes related to building trust influence enterprise growth? Design/methodology/approach: The research used a one-time survey method with the unweighted sample design, using mixed techniques: CATI telephone interviewing and CAWI web interviewing. The survey operator was a database of the 500 largest companies in Poland (according to the ranking of the Rzeczpospolita website). Based on the random sampling method, a research sample of 179 companies was collected. Findings: The study showed the impact of leadership attributes, i.e. attitudes of acceptance of others and open-mindedness, honesty and adherence to the rules, consistency in making decisions, compassion and empathy, on the process of building employees' trust in managers. Significant relationships between vertical trust and intra-organizational processes have also been identified. The results of the study confirmed the impact of vertical trust on both intra 24 organizational processes and the development of enterprises. Research limitations: Due to their quantitative nature (survey research), the study results lead to limited conclusions. Practical implications: The results provide insights into the use of leadership attributes in building organizational trust, which can support a trust-based organizational culture in modern companies. Social implications: The research results presented in this paper point to the important role of the manager in stimulating organizational trust in large companies. Originality/value: In a cognitive sense, the results contribute to understanding the role of leadership in building vertical trust and its impact on intra-organizational processes.

Here we propose for the first time a temporal intuitionistic fuzzy extension of the Hungarian method for solving the Travelling Salesman Problem (TIFHA-TSP) based on intuitionistic fuzzy logic and index matrices theories. The time for passing a given route between the settlements depends on different factors. The expert approach is used to determine the intuitionistic fuzzy time values for passing the routes between the settlements. The rating coefficients of the experts take the times into account. We are also developing an application for the algorithm's provision to use it on a real case of TIFHA-TSP.

Extending Word2Vec with domain-specific labels

Choosing a proper representation of textual data is an important part of natural language processing. One option is using Word2Vec embeddings, i.e., dense vectors whose properties can to a degree capture the “meaning” of each word. One of the main disadvantages of Word2Vec is its inability to distinguish between antonyms. Motivated by this deficiency, this paper presents a Word2Vec extension for incorporating domain-specific labels. The goal is to improve the ability to differentiate between embeddings of words associated with different document labels or classes. This improvement is demonstrated on word embeddings derived from tweets related to a publicly traded company. Each tweet is given a label depending on whether its publication coincides with a stock price increase or decrease. The extended Word2Vec model then takes this label into account. The user can also set the weight of this label in the embedding creation process. Experiment results show that increasing this weight leads to a gradual decrease in cosine similarity between embeddings of words associated with different labels. This decrease in similarity can be interpreted as an improvement of the ability to distinguish between these words.
