Análise das concepções prévias dos estudantes sobre meteorítica no último ano do ensino fundamental
Authors: Targon Tiberio Carolina
Published: July 2024

Este artigo apresenta parte dos resultados de uma pesquisa realizada com alunos do último ano do Ensino Fundamental II que identificou as concepções prévias sobre Astronomia e Meteorítica presentes nos estudantes a partir da qual foi proposto um material didático suplementar com base nos resultados obtidos. A abordagemmetodológica se baseou em entrevistas com grupos focais, compreendendo 8 a 10 estudantes de três instituições públicas na cidade de São Carlos – SP. A análise dos dados foi realizada seguindo a metodologia de Análise de Conteúdo e Análise Temática. Foi observado que as concepções prévias dos alunos estão profundamente relacionadas a conceitos desatualizados ou superficiais, erros conceituais e crenças religiosas. Este resultado corrobora com pesquisas anteriores que apontam para uma falta de preparo dos docentes para lecionar conteúdos de Astronomia, fundamentada na falta deste tipo de conteúdo na sua formação inicial e continuada. A partir disso, utilizando os dados levantados como referência, foi elaborada uma revista de divulgação científica, contemplando as perspectivas dos alunos e buscando uma maior correlação com as teorias científicas contemporâneas, com o objetivo de contribuir para uma aprendizagem significativa.

Published: July 2024

This study investigated the production and physical and chemical characteristics of eight sour passion fruit genotypes cultivated in Baixo Acre, AC. Evaluation of fruit number (FN), productivity (PRO), longitudinal diameter, transverse diameter (LD and TD), peel thickness (PT), average fruit mass (AFM), pulp mass (PM), juice yield (JY), soluble solids (SS), titratable acidity (TA), ratio, and pH of genotypes H1, H3, R, V1, V2, V3, V4, and V5 was performed. Univariate, multivariate, and Pearson's correlation analyses were performed. Univariate analyses revealed that the genotype H1 stood out in terms of AFM, JY, and PRO; H3 for TD, LD, JY, and pH; H1, H3, V1, and R for LD; H3 and V5 for pH; and V4 and V5 for NF. A strong positive correlation was observed among the physical variables AFM, PM, LD, and TD. Four genotypes groups were obtained for both genetic divergence and PCA. The H1 genotype presented higher productivity, and the H3 genotype presented better fruit physical attributes.

With the limitation in the availability of water for agriculture and the high costs of fertilizers, it is necessary to adopt strategies for water and nutritional management of agricultural crops. The objective of this study was to evaluate the morphological and physiological characteristics and productivity of potato under the influence of suppression of irrigation and fertigation in Jaboticabal, SP, Brazil. The experiment was carried out in randomized blocks, conducted in the field, using a 3 x 2 factorial scheme. Different times of irrigation suppression were studied at 80, 90 and 100 days after planting, along with forms of fertigation, following the rate of crop absorption and equivalent fertigation. The imposition of irrigation suppression at 100 days, linked to fertigation following the rate of crop absorption, showed a positive effect on the aerial fresh mass of the potato variety studied, especially promoting the increase in productivity, which was 47.82 t ha-1, and efficiency in water use, which was 10.53 kg of tubers per cubic meter of water. This observation indicates that the application of fertilizers, in sync with the needs of the crop, can improve the efficiency of water use and increase productivity. These findings highlight the importance of integrated strategies to optimize potato cultivation and make it more resistant to adversity, seeking a more sustainable and productive agriculture.
Impact production in higher education: shaping future change makers through film education
Authors: Loader Reina-Marie , Maasdorp Liani
Published: July 2024

This article considers impact production (using film and other forms of storytelling as the core of a social change strategy) as an important component of well-rounded film education programmes that seek to shape a new generation of socially and environmentally conscious film-makers. Through desk research, interviews and a survey, we found that opportunities to learn about impact production at higher education institutions are limited and expensive, while open-access resources are numerous, but can be overwhelming for those new to the field. We interview practitioners who specialise in: (1) raising awareness about what impact production entails; (2) practically implementing impact production strategies; and (3) educating film-makers in how to design impact campaigns. We analyse two case studies from Majority World countries to demonstrate strengths and weaknesses of existing impact teaching and training. The data gathered inform a theorisation of how impact production can be incorporated into formal educational practices worldwide. The article conceptualises what ‘impact production film education’ entails in a higher education context. This includes unpacking the interdisciplinary and practice-based nature of impact production. The intention is to shine light on the pedagogical value of impact production for shaping a new generation of film-makers who are technically equipped to tell compelling stories, and intellectually committed to using film as a tool for change.

Published: July 2024

This case study centres on the Ubuntu Collaboration Model introduced to Bournemouth University in the UK in 2018. Initially focused on undergraduate teaching, the model is now embedded as part of the university’s practice-based and industry-focused Media Production master’s programmes (2019–ongoing). The goal of this initiative is to develop and install a practical approach to film teaching that deliberately fosters a consciousness of cross-cultural collaboration among emerging independent film-makers coming from diverse backgrounds. The model is founded on the principles of the African philosophical concept of Ubuntu, which suggests, among other things, that we can only progress productively through a shared value system that finds expression in respectful social interaction (that is, collaboration). Co-authored with master’s students, this case study contextualises and analyses the experiences of the master’s film production cohort who were part of this pedagogical journey in 2022/3.
homem influencia o outro?
Authors: De Almeida Edwirgens Aparecida Ribeiro Lopes
Published: July 2024

Este breve estudo pretende percorrer uma trajetória das produções orientadoras da conduta de mulheres pelo discurso masculino na Idade Média e a repercussão dessa produção, realizada por homens, na escrita da escritora Cristina de Pizán, na Idade Média, e na escrita de Cervantes, na entrada da Idade Moderna. Sabe-se que grande parte dessa produção tem teor moral e religioso, sobretudo porque têm sua gênese no período de predominância no pensamento católico sobre a região Ibérica, o que fomentou os discursos misóginos, tendo em vista a inferioridade da mulher frente ao homem. Contudo, nosso propósito não é examinar tais narrativas ficcionais, no entanto, sugerir que o leitor adentre aos escritos desses autores a fim de averiguar como a autoria, seja de homem ou de mulher, foi, num plano superficial, conformadora com o discurso predominante, e, por outro lado, tanto o homem quanto a mulher, lançou mão das representações literárias aqui sugeridas, buscaram estratégias para registrar o lugar da mulher, mesmo contra as práticas e o discursos predominantes da tradição.

Religiões e religiosidades na historiografia
Authors: Ribeiro Ferreira Junior Daniel , Vinícius de Freitas Reis Marcos
Published: July 2024

O campo de produção historiográfica sobre as religiões e religiosidades é imenso e complexo. Várias abordagens e perspectivas têm sido adotadas pelos historiadores ao longo dos tempos para entenderem os dois fenômenos de estudo distintos. Neste sentido, o presente estudo tem o objetivo de apresentar como a historiografia buscou, ao longo dos tempos, compreender a questão das religiões e religiosidades. Para isto, movemos num primeiro momento, aspectos mais tradicionais a partir da teoria positivista, onde possuía um olhar estigmatizante, sobretudo, pelo olhar eurocêntrico. Num segundo momento a análise está centrada em teorias, ainda que produzidas na Europa, porém, com conteúdos que procuravam entender como as práticas religiosas estão entrelaçadas com estruturas sociais, econômicas e políticas, bem como com questões de gênero, classe e etnia, isto tudo pelo olhar da Escola dos Annales, principalmente em sua última fase. Por fim, construímos um diálogo entre a História Cultural e a decolonialidade a fim de inserir a questão dos indígenas e de como a cultura religiosa destes sujeitos pode ser vislumbrada sem que o aspecto do estigma esteja presente.
Ex-voto, Teatro e Direitos Humanos
Authors: Dos Santos Mendes Everaldo
Published: July 2024

Na peça “O Pagador de Promessas” [1960], do teatrólogo Dias Gomes, Zé-do-Burro, para cumprir uma promessa pendente com Iansã pela cura de Nicolau, divide sua propriedade rural entre os pobres e carrega uma cruz de madeira por sessenta léguas, para depositá-la na Igreja de Santa Bárbara [Salvador, Bahia, Brasil]. Partindo da teologia como reflexão crítica da práxis histórica, investiguei a ação ex-votiva de Zé-do-Burro em “O Pagador de Promessas”, de Dias Gomes, imbricada em ex-voto, teatro e direitos humanos. No itinerário teórico-metodológico, elegi a pesquisa qualitativa, de impostação bibliográfica e documental. Zé-do-Burro e Rosa chegam à igreja de madrugada. Padre Olavo recusa-se a receber o ex-voto de Zé-do-Burro, impedindo-lhe a desobriga. No ex-terior da igreja, Zé-do-Burro é explorado por candomblecistas e jornalistas. Permanece, teimosamente, nas escadarias do espaço litúrgico católico, onde recebe apoio dos pobres, defendendo-lhe o direito de pagar a promessa. Pe. Olavo aciona a polícia, estabelecendo-se um confronto com os manifestantes —  o que culmina na morte de Zé-do-Burro. Na última cena, os capoeiras entram na igreja com a cruz ex-votiva; sobre ela, o corpo de [finado] Zé-do-Burro.
The Potential Significance of Microwave-Assisted Catalytic Pyrolysis for Valuable Bio-Products Driven from Albizia Tree
Authors: Abd Maha Faisal , AL-yaqoobi Atheer M.
Published: July 2024

The objective of this study is to investigate the feasibility of Na2CO3 and ZSM-5 as catalysts in the microwave pyrolysis of Albizia branches. An evaluation was conducted to determine the influence of power applied, experimental time, particle size, and catalysis type and ratio on the quality and quantity of pyrolysis products. Established methods such as GC-MS, FTIR, HHV, SEM, EDX, and BET were used to characterize the properties of bio-oil and biochar produced. The results demonstrated that using both catalyst types led to a substantial enhancement in biogas production. The improvement ranged from 5% to 41% with Na2CO3 and reached 45% with ZSM-5. At a lower power level of 300 W, the bio-oil yield augmented from 28% to 40% and 53% when using ZSM-5 and Na2CO3, respectively. The GC-MS analysis revealed that the utilizing of catalysts enhanced the levels of aromatic compounds, esters, and alcohols in bio-oil, along with an increase in the higher heating value (HHV) from 19.5 MJ/kg to 22 MJ/kg and 24.2 MJ/kg using Na2CO3 and ZSM-5, respectively. Moreover, the biochar's surface area and pore volume experienced a considerable rise, going from 0.5512 m2/g and 0.00011 cm3/g to a higher value of 115.2073 m2/g and 0.0774 cm3/g when treated with Na2CO3. The data indicated that both catalyst types enhanced the generation of CH4, and CO2 was lower with ZSM-5. The utilization of catalysts improves the quality of the biofuel produced and promotes the efficiency of the process in terms of energy consumption and processing time.
AN ANALOGY OF GENDER-BASED VIOLENCE AND POLICE CORRUPTION IN MATTERS RELATED TO VIOLENCE AGAINST WOMEN DURING THE COVID-19 PANDEMIC
Authors: Smart Caroline
Published: July 2024

In March 2020, an unprecedented new Corona phenomenon began to emerge, governments were forced to impose lockdowns, restrictions, quarantines and isolations globally to contain the virus. While these measures were necessary to stop the spread of this new phenomenon, it exposed the realities of women's gendered lives. In South Africa, the Covid-19 pandemic entwined with two existing endemics: gender-based violence and corruption within the South African Police Service (SAPS). Gender-based violence is a social-ill inextricably linked to gender-based structural inequalities and state institutions riddled with corruption. The exponential rise in gender-based violence related to Covid-19 once again captures the travesty of a police service paralysed by corruption and afflicted by incompetence to execute its tasks. The police service is unable to defend safety and justice when they are perpetrators themselves. The focus of this article is on the surge of gender-based violence as a consequential effect of Covid-19 restrictions, compounded by an unaccountable police service.

The paper describes the stages of designing the technological end hole milling cycle and presents the developed CONICALINT software, which generates a G-code with argument lists used to call up a technological cycle from the CNC system memory. The developed algorithm for the technological end hole milling cycle has a branched structure, since it can choose between two methods for calculating the internal cycle parameters and two milling methods – climb down and climb up. The calculation of the internal technological cycle parameters consists of calculating the coordinates of the points necessary to construct the helical path of the cutting tool, as well as the maximum permissible value of the helical pitch within a given set of input parameters. The initial calculation data are represented by thirteen parameters characterizing the geometry of the cutting tool, the geometry of the required machined surface, as well as the parameters that determine the milling method and the method for calculating the cutting mode and the starting points of the cutting tool path. We identified eight boundary conditions that determine the permissible values of the input parameters. Based on these conditions, we designed a system of inequalities with a set of error messages displayed to the user if any of the input parameters is entered incorrectly. The developed Gcode of the technological cycle subprogram for a CNC machine calculates the tool movement both along a helical and a conical helical path, depending on the input parameters, which allows using it to program cylindrical and conical hole milling. The developed CONICALINT software is a visual addition to the developed technological cycle of hole milling. The developed CONICALINT software is a visual addition to the developed technological hole milling cycle, which allows generating a control G-code with a set of twelve arguments.

The potential of bacterial endophytes on orchids
Authors: Aneesa Ansiya , Parvathi Rajeevan , Gangaprasad Appukuttannair , Shiburaj Sugathan
Published: July 2024

Orchids are one of the most exquisite and diverse plant species in nature. The seeds of orchids are non-endospermic and, therefore, dependent on endophytes for germination, growth, and adaptability. Orchids are prized for their beauty and therapeutic and culinary qualities by naturalists and the general public. Many orchid species are now endangered or vulnerable due to collectors' eagerness to take them. Current studies on orchids have concentrated on isolating and identifying the mycorrhizal and non-mycorrhizal endophytes that either directly or indirectly help orchids to grow, develop, and produce beneficial secondary metabolites. In orchids, bacterial endophytes play an essential role in the formation of mycorrhizae and the stability of relationships between plants and fungi. Endophytic bacteria can grow in orchids by producing phytohormones, doing photosynthesis, fixing nitrogen, promoting the mineral nutrition cycle, forming siderophores, and producing diverse beneficial metabolites to improve biomass production, stress tolerance, and biocontrol of potential phytopathogenic fungal species. This article examines how endophytic bacteria are associated with orchids and their potential growth-promoting abilities.

Authors: Duan Kaili , Xiang Yu , Deng Yilong , Chen Junman , Liu Ping
Published: July 2024

Objectives

It has been reported that serum Clara cell secreted protein 16 (CC16) is a potential biomarker for lung injury diseases, but currently, there is no other method that is faster, more accurate, or more sensitive being applied in clinical practice apart from ELISA. The current study was designed to established a magnetic nanoparticles chemiluminescence immunoassay (MNPs-CLIA) for highly sensitive automated detection of serum Clara cell secretory protein 16 (CC16), and validated its diagnostic performance for lung disease.

Methods

The study included the expression of CC16 recombinant protein, the preparation and screening of its monoclonal antibody (MAb), as well as the construction, optimization and analytical evaluation of the MNPs-CLIA method. The clinical application value of this method was investigated by detecting CC16 level in 296 serum samples.

Results

The linear range of the MNPs-CLIA assay system was 0.2–50 ng/mL, and the limit of detection was 0.037 ng/mL. Performance parameters such as specificity, recovery rate, and precision can meet the industry standards of in vitro diagnostic reagents. The established method reveals consistent results with ELISA (R2=0.9962) currently used clinically, and it also exhibits satisfactory diagnostic efficacy of silicosis, chronic obstructive pulmonary disease (COPD), and pulmonary sarcoidosis, with areas under the curve (AUC) of 0.9748, 0.8428 and 0.9128, respectively.

Conclusions

Our established MNPs-CLIA method has the advantages of automation, high throughput, rapidity, and simplicity, and can be promoted for widely popularized in clinical applications. MNPs-CLIA detection of serum CC16 has efficient diagnostic potentiality for predicting and diagnosing lung diseases.
Advancing value-based laboratory medicine
Authors: Plebani Mario
Published: July 2024

Following the COVID-19 pandemic, the concepts of value-based medicine (VBM) and value-based laboratory medicine (VBLM) are receiving increasing interest to improve the quality, sustainability and safety of healthcare. Laboratory medicine is well positioned to support the transition to value-based healthcare as it helps to improve clinical outcomes and healthcare sustainability by reducing the time to diagnosis, improving diagnostic accuracy, providing effective guidance for tailored therapies and monitoring, and supporting screening and wellness care. However, the perception of the value of laboratory medicine is still limited, to the extent that it has been defined a “profession without a face”, often lacking visibility to patients and the public. In addition, in recent decades, clinical laboratories have sought to improve the ration between outcomes and costs by increasing efficiency and reducing the cost per test rather than improving clinical outcomes. The aim of this paper is to propose a 10-point manifesto for implementing value-based laboratory medicine in clinical practice.
Ferecide l’oscuro
Authors: Salomone Andrea
Published: July 2024

Pherecydes’ pseudepigraphic letter to Thales (Diog. Laert. I 122) is of uncertain date. It revolves around the idea that the book of Pherecydes should be interpreted allegorically. The aim of this paper is twofold: on the one hand, to contextualise the composition of the epistle through the examination of ancient witnesses who focus on Pherecydes’ obscurity; on the other hand, it shows to what extent Numenius, Celsus and Porphyry’s allegoric interpretation has misled some authoritative modern reconstruction of Pherecydes’ doctrines, as it is today generally agreed that he taught the immortality of the human soul and cycle of reincarnation.

Comparative study of DCT-and DHT-based OFDM systems over doubly dispersive fading channels
Authors: Elshawadfy Sherif A. , Hussein Aziza I. , Salama Gerges M.
Published: July 2024

In high-mobility operating scenarios orthogonal frequency division multiplexing (OFDM) system lacks its optimality, intercarrier interference (ICI) occurs and the Doppler shifts deteriorate the orthogonality of the subcarriers. However, this problem can be overcome by utilizing complicated equalizers at the receiver. Discrete cosine transform (DCT) and discrete Hartley transform (DHT) have been used instead of discrete Fourier transform (DFT) in the standard OFDM system. The performance results achieved enhancement over dispersive selective channels that cannot be accomplished with a standard OFDM system, even with utilizing complex equalizers. In this paper, the performance of the DCT-based OFDM system and DHT-based OFDM system is compared and analyzed with respect to DFT-based OFDM system performance over doubly dispersive fading channel at various Doppler shifts, the block diagrams of the proposed systems are provided to simplify the theoretical analysis by making it easier to follow. Simulation results emphasized that the performance of DCT and DHT-based OFDM systems under doubly dispersive fading conditions scenario outperforms DFT-based OFDM system of order 3 dB energy per bit to noise power spectral density ratio (Eb/N0).
Investigation properties of ultra-high performance concrete incorporating pond ash
Authors: Soni Abhishek , Nateriya Raman
Published: July 2024

The study aims to substitute river sand used in ultra-high performance concrete (UHPC) with pond ash (PA), a waste by-product from the Sikka thermal power station in Gujarat, India, at replacement levels ranging from 0 to 20%. Also, 20% of the cement was replaced with ground granulated blast-furnace slag, which is a sustainable, eco-friendly material. As a result, this concrete is both environmentally and economically feasible. Experimental analysis evaluated the workability, compressive strength, split tensile strength, flexural strength, and microstructure of the UHPC mixtures. Incorporating 10% PA as a sand replacement enhanced the compressive strength, reaching 117 MPa at 90 days, as well as the flexural strength of 23 MPa and the split tensile strength of 14 MPa. The strength is positively impacted when 10% of the river sand is replaced with PA, while the strength of UHPC appears to be diminished if PA content is increased beyond 10% replacement of sand. Petrographic microscopy and X-ray diffraction were used to study the microstructure of UHPC made with PA. When PA was used instead of sand, the mortar mass solidified and became denser, resulting in an improved microstructure of the UHPC with fewer surface cracks. With the inclusion of PA, the calcium silica hydrate gel content of the concrete increases, and enhanced performance of UHPC up to a certain amount of replacement has been observed.
„... dass sich halt keiner ausgeschlossen fühlt.“ Wahrnehmungen von und Einstellungen zur Verwendung nicht-deutscher Erstsprachen im Unterricht
Authors: Fischlhammer Laura , Buchner Elisabeth , Elspaß Stephan
Published: July 2024

This article examines perceptions of and attitudes towards the use of non-German languages in Austrian schools from the perspective of students and teachers. By differentiating between teachers, students with exclusively German L1 and students with a non-German L1, different perspectives on code-switching in group work situations are examined. For this purpose, data was collected via online questionnaires, semi-structured interviews and focus group discussions between students. The results show that switching to another language in group work settings is perceived as inappropriate, in particular by those students who have no competence in a language other than German. Moreover, they associate switching with poorer performance in class and interpret the use of a language other than German in class to be antagonistic or talking behind the back of people who do not speak that language (“gossiping”). In contrast, – and contrary to the assumption that they evaluate language switches in the classroom more negatively due to stricter normative views – teachers show a consistently more positive perception of code switching behaviour and its multilingual speakers. It can be concluded from the findings that multilingualism in the school context and its overall benefits should not only be addressed in teacher training, but that it would also be useful to raise students’ awareness of multilingual practices.
„Et fehlt dä Ruhrpott, verstehste!“. Dialekt als Stance-Ressource in der digitalen Interaktion
Authors: Merten Marie-Luis
Published: July 2024

This article sheds light on the functionality of dialect performance in digital writing on Instagram. Within an interactional-sociolinguistic framework, two Instagram posts (by aroundtheword; responsible: ZDF) which deal with the German-speaking dialect area including follow-up communication (1,068 comments) are analysed. The main research questions guiding this article are (1) for what specific purpose dialect is used in the analysed Instagram comments and (2) which functional patterns of dialect use can be identified in this form of digital interaction. The corpus study presented follows a mixed methods approach and thus integrates descriptive quantitative and qualitative analyses. In theoretical and methodological terms, the study is based on widely accepted models of stance research (Du Bois 2007) as well as media and internet linguistic concepts (Beißwenger 2020). From this theoretical perspective, Instagram communication is investigated as a (typical) format of a digital and interaction-orientated stance practice. The present study provides insights into the stance potential of dialect performance: it not only serves as a marker of authenticity and a resource for identity construction (referring to regionality) but is also an essential means of community building (as part of alignment) and epistemic-evidential positioning.

EFFICIENCY OF AUTONOMOUS HEATING SYSTEM IN INTERMITTENT MODE WITH HEAT ACCUMULATOR
Authors: Balasanian H. ,   Odessa Polytechnic National University, Semenyii A. ,   Odessa Polytechnic National University
Published: July 2024

Theeffectiveness of the autonomous heating system in intermittent mode with a heat accumulator of the building of the educational building of the Odessa National Polytechnic University was studied. The main requirements for solving the task of optimizing the room heating process are formulated. Ways to increase the efficiency of morning room heating are considered. On the basis of the developed mathematical model of the dynamics of thermal processes of the elements of the autonomous heating system, the regimes of the thermal load of the heating system when the temperature of the outside air changes are investigated. The main directions for improving the heat supply of buildings in the mode of intermittent-frequent heating are proposed and their practical application in modeling and research of the system is taken into account. The results of optimizing the daily load schedules of the main elements of the autonomous heating system under variable external conditions are presented. The optimal daily schedules of the dynamics of indoor air temperature and network water temperature of the heating system are given. The dependence of the filling factor of the load schedule of the heating system and the heat generator on the outside air temperature in the range from 5 to –15 °С was studied. The effect of daily heat accumulation on the reduction of the nominal thermal power of the heat generator was studied. Heat savings were evaluated based on the results of optimization of load modes of the proposed system in the intermittent heating mode compared to the 24-hour heating mode, which amounted to 25.2%, respectively. Based on the results of the study, it was concluded that daily heat accumulation for heating systems operating in intermittent mode is an effective measure for increasing the efficiency of morning room heating, achieving the maximum possible thermal power of the heating system during heating and reducing its duration to 1 hour. Keywords: intermittent heating mode, mathematical modeling, heat accumulation, morning heating of the room, load schedule filling factor, optimization of load modes
Unternehmensüberwachung als Managementaufgabe
Authors: Zünd Andre
Published: July 2024

Bei der Erarbeitung einer Gesamtkonzeption der Unternehmensüberwachung gibt uns das wissenschaftliche Schrifttum nur geringe Hilfe. Zwar besteht kein Mangel an Literatur über spezifische Überwachungsprobleme und -institutionen wie das Rechnungswesen, das Controlling und die Revision. Erst in jüngster Zeit wendet sich die Theorie vermehrt der Organisation der Überwachung zu. Ein praxisorientiertes Überwachungssystem muss daher pragmatisch angegangen werden. Die Organisation der Überwachung stellt eine Auswahl von Elementen des Überwachungsprozesses und ihre Einordnung in einen Gesamtzusammenhang dar. Professor Dr. André Zünd zeigt in seinem Beitrag diesen Zusammenhang auf und arbeitet die Rolle des Controlling heraus. Im Vordergrund steht dabei die Situation in der Schweiz.

Organisation des Controlling
Authors: Welge Mortin K.
Published: July 2024

Gegenwärtig befassen sich zahlreiche Unternehmungen mit der Einführung eines Controllingsystems. Dabei ist die organisatorische Gestaltung der Aufbau- und Ablaufstruktur des Controlling ein wichtiger Problemkreis. Die Controllingtheorie und Controllingpraxis haben eine fast unübersehbare Vielzahl von Vorschlägen zur organisatorischen Gestaltung des Controlling entwickelt. Das Spektrum reicht vom Buchhalter, der kurzerhand die Bezeichnung "Controller" erhält, bis zur Einrichtung eines Vorstandsressorts für Controlling. Da es keine allgemeingültige Lösung des Strukturierungsproblems geben kann, sollen die bereits vorliegenden Konzepte nicht noch um einen weiteren Vorschlag ergänzt werden. Statt dessen wird beabsichtigt, durch Beantwortung der beiden nachstehenden Kernfragen das Strukturierungsproblem zu verdeutlichen und dem Gestalter Anhaltspunkte zur Lösung seines Gestaltungsproblems zu geben: • Welche organisatorischen Gestaltungsparameter stehen dem Gestalter grundsätzlich zur Verfügung? • Welche Faktoren beeinflussen die Gestaltung der Controllingorganisation?
Strategisches Produktionscontrolling bei Einführung neuer Technologien
Authors: Hoitsch Hons-Jörg
Published: July 2024

Die Einführung neuer Technologien hat in jüngerer Zeit dazu geführt, dass neben der primär auf Produkt-/ Markt-Potentiale gerichteten externen Strategischen Unternehmensführung intern orientierte Ansätze immer stärker in den Vordergrund treten. In einem solchen funktionalisierten Konzept der Strategischen Unternehmensführung kommt der Unterstützung des Strategischen Produktionsmanagements durch ein strategisches Produktionscontrolling besondere Bedeutung zu. Professor Hoitsch beschreibt in seinem Beitrag zunächst Aufgaben und Instrumente des strategischen Produktionscontrolling. Die Anwendung des vorgestellten Instrumentariums wird anschließend beispielhaft am Fall der Einführung eines Flexiblen Fertigungssystems (FFS) in einer mittelständischen Industrieunternehmung verdeutlicht.
Produkthaftungsmanagement
Authors: Schünemann Wolfgang B.
Published: July 2024

Das neue Produkthaftungsgesetz ist zum 1.1.1990 in Kraft getreten, was zu einer beträchtlichen Verschärfung der Produktverantwortung und zu einer veränderten Risikosituation keinesfalls nur für produzierende Unternehmen führt. Zu beachten ist insbesondere die versteckte Vorwirkung des neuen Rechts, da es für alle Produkte gilt, die, obschon vielleicht vor lnkrafttreten produziert, nach lnkrafttreten "in den Verkehr gebracht", d.h. ausgeliefert werden. Die Kenntnis der wesentlichen gesetzlichen Regelungen ist für den Controller unerlässlich. Schünemann zeigt in seinem Beitrag die wichtigsten bevorstehenden Änderungen und Zusammenhänge bei der Produkthaftung auf und erläutert sich ergebende Konsequenzen.
Operatives Controlling durch Erfolgsspaltung
Authors: Dellmann Klaus , von Peter Wilden Mitarbeit
Published: July 2024

Eine zentrale Aufgabe des Vertriebscontrolling ist die Analyse des Produkterfolges. Sie ist der Ausgangspunkt zur Produktbeurteilung und gegebenenfalls der Einleitung von Steuerungsmaßnahmen. Klaus Dellmann stellt in seinem Beitrag ein Modell vor, das auf der Idee der Isolierung von Einflussgrößen des Erfolgs beruht. Die Isolierung der einzelnen Einflussgrößen wird zunächst theoretisch erklärt und anschließend an einem Beispiel verdeutlicht. Alle Analysenergebnisse werden dann zu einem Kennzahlensystem zusammengefasst, das eine fundierte Produktbeurteilung und -steuerung unterstützt.
Controlling und Frühaufklärung
Authors: Krystek Ulrich
Published: July 2024

Ausgehend von Frühaufklärungssystemen im militärischen Bereich wurde der Gedanke einer Frühaufklärung von Chancen und Bedrohungen für Unternehmungen ab Ende der 70er Jahre in die betriebswirtschaftliche Forschung und Praxis eingeführt. Eine steigende Anzahl theoretischer Konzepte sowie die Akzeptanz und Bewährung solcher Systeme in der industriellen Praxis belegen die Relevanz einer Frühaufklärung für die Unternehmung. Im nachfolgenden Beitrag gibt Ulrich Krystek einen Überblick über die bekannten Konzepte der Frühaufklärung und zeigt aktuelle Entwicklungstendenzen auf. Er untersucht kritisch die Rolle des Controlling als Träger dieser sensitiven lnformationsfunktion.
Organisation: Controlling und Interne Revision
Authors: Heigl Anton
Published: July 2024

Die ,Stellen' Controlling und Interne Revision haben in der Vergangenheit gleichermaßen bedeutende Entwicklungen durchlaufen. Gleichzeitig lassen sich zum Teil Anzeichen für eine Konvergenz von Controlling und lnterne Revision erkennen. Es stellt sich daher immer wieder die Frage, wie eine Abgrenzung in funktionaler und institutioneller Hinsicht erfolgen kann. Da es keine Potentlösungen gibt, stellt Anton Heigl grundsätzliche Überlegungen an und unterbreitet Vorschläge für alternative Organisationskonzepte.
Euro-Marketing-Controlling
Authors: Meissner Hans Günther , Auerbach Heiko
Published: July 2024

Mit der Einführung des europäischen Binnenmarktes werden Außenhandelsgeschäfte sowie die internationale Ausrichtung des Marketing zahlreicher deutscher Unternehmen weiter an Bedeutung gewinnen. Dabei kommt es vor allem auf die Entwicklung von spezifischen Marketingstrategien an, die die unterschiedlichen sozioökonomischen Felder berücksichtigen und eine differenzierte Informationsversorgung erforderlich machen. Hans Günther Meissner und Heiko Auerbach kennzeichnen in ihrem Beitrag die Konzeption eines Euro-Marketing-Controlling, dessen zentrale Aufgabe in der Abstimmung der Informationsbeschaffung und Informationsverwendung hinsichtlich des gemeinsamen europäischen Binnenmarktes besteht.
Controlling im F&E-Bereich.
Authors: Fischer Joachim
Published: July 2024

Ständig steigende Forschungs- und Entwicklungsaufwendungen, der stärkere internationale Wettbewerbsdruck, die zunehmende Komplexität der Produkte und die kürzer werdenden Innovationszyklen haben Überlegungen zur verstärkten betriebswirtschaftlichen Steuerung des F&E-Bereiches durch den Aufbau eines spezifischen F&E-Controllingsystems in den Mittelpunkt des Interesses gerückt. Joachim Fischer vertritt die Auffassung, dass die Implementierung eines solchen "F&E-Controllings" Anforderungen an das Controllingsystem eines Unternehmens stellt, für das dieses aus seinem bisherigen Verständnis heraus nicht per se gerüstet ist. Ziel der vorliegenden Arbeit ist es, die vom Verfasser in einer langjährigen Tätigkeit im Unternehmenscontrolling eines Unternehmens der pharmazeutisch-chemischen Industrie gewonnenen Einsichten aufzuarbeiten, um daraus einige Thesen zum Aufbau eines F&E-Controllings zu gewinnen.
Ökologisches Controlling.
Authors: Wagner Gerd Rainer , Janzen Henrik
Published: July 2024

Die Wirkungen der Unternehmenstätigkeit auf die ökologische Umwelt verlangen verstärkte Aufmerksamkeit in den Unternehmerischen Planungs- und Entscheidungsprozessen. Führungsunterstützung in diesem Sinne wird in letzter Zeit häufig unter dem Stichwort "Ökologisches Controlling" (bzw "Umwelt-" oder "Öko-Controlling") diskutiert. Dabei dominiert bislang eine Ausrichtung, die sich eng an den Prinzipien des externen Rechnungswesens orientiert. ln Kontrastierung dazu versuchen die Autoren des vorliegenden Beitrags, mit ihrem Vorschlag einer "Umwelt-Budget-Rechnung" einen Ansatz zu entwickeln, der konzeptionell und anwendungsbezogen von einer Verankerung des "Ökologischen Controlling" im Bereich des internen Rechnungswesens ausgeht und damit ein Instrument tatsächlicher unternehmerischer Entscheidungshilfe bietet.
