Authors: Padjung Rusnadi , Ridwan Ifayanti , BDR Muh. Farid , Nasaruddin N. , Anshori Muh. Fuad
Published: January 2022

Productivity of superior genotypes often did not satisfyingly achieve its genetic yield potential. Interaction between genetics and environmental factors more likely to driven the final yield of the varieties. The concept of balanced fertilization is carried out by referring to the creation of a balance of macro-nutrients in the soil so that plants can produce optimally. The research was conducted in a form of experimental study at Tarowang village, Takalar Regency during growing season of 2021 from May to September 2021. A split plot design was used with fertilization package as the main plot and superior varieties as subplots. Three fertilization packages combined inorganic and organic fertilizer were used, namely fertilization package consisted of N: P: K with ratio of 225:100:75, fertilizer package that consisted of N: P: K ratio of 200:100:50 + KNO3 25 kg + Biotani 5cc L-1, and fertilizer package that consisted of N: P: K with a ratio of 200:100:50 + KNO3 25 kg + Ecofarming 5cc L-1. Six superior varieties used were Nasa 29, JH-37, Bisi 2, Bisi 18, SINHAS 1 and NK7328. Based on the level of both factors, 18 treatment combinations were obtained and repeated three times. Responses of maize varieties to fertilization packages, consisted of different combination and dosage of NPK fertilizers, KNO3 and organic fertilizers, were varied between varieties. The treatment of fertilization package of N: P: K = 225:100:75 with Bisi 2 variety gave the highest maize productivity, namely 12.39ton ha-1

Published: January 2022

Salinity screening under hydroponic Deep Flow Technique (DFT) has not been widely studied, especially on the nature of rice tolerance to salinity stress. According to previous screening studies, this method was effective in distinguishing the nature of rice tolerance to salinity stress. However, they were tested only at generative phase. Therefore, evaluation on screening method with hydroponic DFT at all phases of paddy growth is essential. The objective of this study is to evaluate the filtering under hydroponic DFT at all paddy phase and to determine secondary character that support productivity which can be utilized as selection character in this screening process. The experiment was arranged with a complete nested group design with nested replication is the NaCl stress. There were 5 (Five) tested rice varieties and the stress environment consisted of three levels: 0, 60, and 120 mM of NaCl, all with 3 (three) replications. The nutrient culture screening was adapted to the modified Egdane method. The results showed that screening under hydroponic DFT was effective at the concentration of 60 nM of NaCl. The best selection character was yields per clump, number of productive tillers and total chlorophyll. The variety of Jeliteng, Ciherang and Inpari 34 of Salin Agritan, were classified as tolerant group. This hydroponic DFT Filtering method could be recommended as one salinity screening method for all paddy growing phases

Published: January 2022

The demand for tomatoes is increasing along with population growth. However, this demand needs to be supported by increasing tomato productivity. One way to increase this is the assembly of high-yielding tomato varieties. In the assembly of varieties, the F2 generation is a generation with high diversity. This becomes important in the process of evaluating and selecting tomato varieties. Genetic variants are the initial capital of plant breeding efforts, which are related to the assembly of varieties to increase the quantitatively and quality of the yield including fruit size, fruit quality and productivity by utilizing the heterotic phenomenon in the assembly of tomato varieties. A research was conducted to evaluate the diversity of generations of biparental crosses using an augmented design. The genotypes used were Mawar (30 plants), Karina (30 plants), F1 genotype of Mawar x Karina (25 plants), Mawar x Karina x Mawar (20 plants), Mawar x Karina x Karina (20 plants), and F2 genotype of Mawar x Karina (200 plants) which were divided into 4 blocks. The results show that the genetic diversity of the F2 population was highest in the characters of plant height, harvest age, fruit length and fruit diameter, with heritability values in the medium to high category

Authors: Hunt Julie A. , Anderson Stacy L. , Winter Matthew D. , Hack George , Berry Clifford R.
Published: February 2022

Accurate interpretation of radiographic images is critical to diagnosing clinical patients. Remote instruction in radiology has become more common at veterinary colleges as academic institutions struggle to fill open veterinary radiologist positions and as a result of the COVID-19 pandemic. This study sought to gather the feedback of fourth-year veterinary students via pre- and post-study surveys ( n = 45) and focus groups ( n = 7) about a newly implemented 2-week long radiology rotation. Ninety-eight percent of students reported having taken an online course before, and on both pre- and post-study surveys, students commonly reported feeling interested, determined, and attentive. On average, students reported that they were neither more nor less engaged than they would have been in an in-person course and that they understood the material neither better nor worse than they would have in an in-person course. Students reported that the key to their success was primarily hard work; secondarily, instructor availability and student ability were important. Students did not rate luck as having much influence on their success. Although diagnostic imaging can be a challenging subject to master, students effectively learned this subject through online instruction. They provided feedback for the course’s continued improvement; their comments centered around improved interactivity, including providing automated quiz questions’ answers and increased instructor availability. Data collected in this study will help to guide further development of the radiology course.

Authors: Kotova T. , Khamadeeva Z.
Published: January 2022

The article discusses the possibilities of using natural, historical, cultural, infrastructural and labor resources for the development of tourism in the territories created in Bashkortostan, geoparks. In 2020, the Bashkir geopark "Yangan-tau" was the first in Russia to join the UNESCO Global Network of Geoparks. In December 2018, the second geopark, Toratau, was created in Bashkortostan. To date, Toratau is a geopark of republican significance, but aspires to international status. There are no restrictions on economic and recreational activities on the territory of geoparks, which provides opportunities for business development, but key geological and other natural and cultural objects are subject to strict protection. The leadership of the republic is aware that at the first stage geoparks need state support and plans to create 55 capital construction projects on the territory of geoparks for a total of more than 1.7 billion rubles by 2025. Of these, 39 will be built by attracting private investment. The appearance of geoparks means an increase in entrepreneurial activity in this area, a significant increase in tourist traffic.
ANALYSIS OF CURRENT ISSUES IN THE REGULATION OF MERGER AND ACQUISITION DEALS BY THE RUSSIAN LEGISLATION
Authors: Kirilin A. , Konotopova E.
Published: January 2022

There is a lapse in the Russian corporate law governing merger and acquisition deals. This is striking as most processes of management streamlining and corporate efficiency boost are in a way related to these deals. Even the existing draft legislation on the issue has been designed to hinder reorganization processes and not facilitate them. It is unclear and controversial to an extent that any reorganization is highly likely to be considered unlawful.

It is clear that realities and related legal challenges require improvements in the regulation of merger and acquisition deals. Incompleteness and lack of detail in the Russian legislative provisions on regulation of M&A deals create a major obstacle for their execution in this country. A law on mergers and acquisitions should address two major issues: ensuring transparency and low cost of the processes involved and balancing the interests of owners and the state. 

Incompleteness and lack of detail in the Russian legislative provisions on regulation of M&A deals create a major obstacle for their execution in this country: the absence of relevant regulatory acts and laws puts at risk the rights of companies taking part in merger and acquisition processes. That is why Russian owners conclude the majority of such deals within foreign jurisdictions.

The amendment of the Russian corporate legislation in line with modern standards and requirements should be moving on gradually but consistently, as it is necessary for today’s economic growth in Russia and the buildup of the Russian economics as an independent and sovereign entity in the global economic system.
LEGAL ASPECTS OF CLASSIFICATION OF INTANGIBLE ASSETS IN MERGER AND ACQUISITION DEALS IN THE TELECOMMUNICATIONS SECTOR
Authors: Kirilin A. , Konotopova E.
Published: January 2022

The article is dedicated to legal aspects of classifying and describing intangible assets in merger and acquisition deals for telecom companies. The absence of proper legal coverage of the issue in Russia leads to considerable discounts on asset value in such deals, which is especially evident because Russia is the leader in their volume among Eastern European countries. An important part of these deals is classification of acquired tangible and intangible assets, intellectual property, including authors’ rights, patents, other components of business model innovations, and their further reclassification.

But today many aspects of digital product creation do not have a detailed and clear description in the Russian legislation, however, they should be clarified and included in the legal documentation for these deals so as to make the most of the deal closing. The starting point of the research in this article is the practical experience of developing professional standards for the creation of intangible assets in content production. Nowadays, the focus in developing professional standards is on the product created, not on the description of the processes involved.

When developing the professional standard for audiovisual translation, the product creation process was analyzed from the point of the activity, which helped to increase the legal protection of created products. The stages of audiovisual product creation and localization were identified and their legal aspects were described.

The legal description of stages of intangible asset production also resulted in defining frameworks for many new professions including game translators, dubbing editors and audiovisual translators.

Published: January 2022

Treatment with intraosseous osteointegrable dental implants is a modern therapeutic method that achieves complete rehabilitation by fully restoring the patient's masticatory function and aesthetics. The success of their application is closely related to the process of osseointegration. Osteointegration is the process of bone formation between the alloplastic material and the surrounding biological environment. The quality and quantity of bone available is a major prognostic factor for the success of dental implants. Some authors evaluate metabolic activity of bone after placement of dental implants or bone grafts using conventional scintigraphy and singlephoton emission computed tomography (SPECT). The aim of the publication is to present the application of the SPECT study with 99mTc MDP in dental implantology.

COVID-19 affected higher educational institutions around the world. This study focused on academics’ perceptions and practices of online education based on their academic discipline and previous online education experience. The survey research design used and an e-survey was conducted in May 2020, during which the lockdown restrictions were rather tight in Turkey. The analyzes were carried out on the responses of 8,242 academics’ using the omnibus chi-square test and t-tests. The results point out that academics’ time allocation to preparation for courses, student counselling, and lectures are varying due to their academic disciplines. Generally, academics have a negative perception of online education though there is a difference between the experienced ones and others. In particular, academics with online education experience exhibited lower negative perceptions of online education than those lacking such experience. Maybe one of the most problematic parts of this transition process for academics is how to ensure the reliability of exams. Our results showed that even the academics with online education experience have a higher level of distrust towards educational measurement and evaluation methods.
Reading and Fighting Patriarchy
Authors: Chappell Deanna
Published: January 2022

In a course whose goals are to unmask patriarchal structures and understand the difference between patriarchy, misogyny, and sexism, students read young adult (YA) feminist novels and critiqued them in light of their new knowledge of issues in education, gender, and politics.  In the context of a term-long project, students were asked to write a synopsis of their chosen book, and an analysis of how the author illustrates gender-based oppression and young people’s resistance.  Using Manne's (2018) definition of patriarchy as an overarching structure, students recommended their books in a series of reviews for distribution to local middle and high school libraries.
Interrogating the "Good" Muslim
Authors: Welji Haleema
Published: January 2022

In this assignment, students learn to critique the frequently stereotypical and problematic depiction of Muslims in media sources. Based on their own linguistic analyses of TV shows, movies, or political speeches, students build arguments about the messaging and judgment of Muslims in the United States. Close linguistic analysis is a powerful method to practice critical-thinking skills as students select and analyze evidence in order to construct original arguments. I select sources that challenge students to question and critique not just Orientalist and racist stereotypes of Muslims but also representations that seem to be positive on the surface but subtly reinforce inequitable expectations of Muslims. This assignment allows students to explore some of the social justice issues facing Muslims in the U.S., such as the reinforcement of Islamophobia, the expectations to prove their allegiance to the nation, and the demand to conform to “good Muslim” expectations. Based on an exploration of their thesis statements, my analysis demonstrates that students used evidence from their sources to build arguments that condemn the perpetuation of stigma associated with Islam and Muslims. Additionally, many students critiqued media sources for subtly encouraging expectations that Muslims need to continually demonstrate patriotism and particular kinds of assimilation in order to be deemed “good” Muslims. Through this and similar assignments, students practice more critical perspectives on media and explore the challenges of representation through the perspectives of marginalized populations.
Writing as Memory Work
Authors: Swiencicki Jill , Lowe Barbara
Published: January 2022

Social justice goals are usually sought in civic or community settings in which stakeholders represent competing frameworks about what is just, good, and true. Modeling for students a way to identify these competing frameworks, and then intervene in deliberations to achieve just ends, is the focus of our assignment sequence. We examine civic deliberations over removing racist public symbols in this assignment for first-year students enrolled in linked rhetoric and philosophy courses. We read broadly in theories of public memory and civic identity, examine in depth one community’s deliberation, and reflect on public symbols in our home communities. The final joint assignment asks students to identify the principles that should guide deliberations about contested public symbols. We found that the assemblage of ideas that the students select from these pre-drafting activities shapes what they think is possible in the work of social justice; in other words, their own standpoint enables and limits what they see in the assemblage of ideas, sometimes limiting the arc of social justice insights and solutions, and sometimes unleashing it. For this reason, reflective writing is a necessary entwined process, one that can develop better awareness of how students’ epistemic norms shape their ability to imagine social justice ends. To most fully realize social justice knowledge, students must not stay bound within the contours of particular deliberations, or inward reflection. Instead, assignments must enlarge the context, asking students to make bigger inquiries into history, context, and relations of domination.
Building Students' Literate Agency through Makerspace Activities in a Two-Year College
Authors: Lee Soyeon
Published: January 2022

This makerspace-based assignment is designed to cultivate students' literate agency and their awareness of semiotic resources in two-year college contexts. The maker movement in education has been predominantly studied in business, science, and engineering fields and in four-year colleges. Networking translingual and transmodal scholarship and the maker movement, I devised a makerspace-based writing assignment as a scaffolding project to support students' analysis on their digital practices in the corequisite developmental writing courses and the composition courses in a community college. Although students' responses varied, I argue that this assignment can benefit two-year college students and offer social implications in multiple ways: it can promote students' access to the emerging trend of the maker movement and DIY fabrication culture; it encourages students to employ their multilingual and multimodal resources with an awareness of their changing literate ecologies; it can help them build their literate agency and transfer the maker mindset to other rhetorical environments such as their workplace or discipline-specific writing situations.
Socialization and Social Justice
Authors: Goode Keisha
Published: January 2022

Students are often told that social justice is both the ideal and the reality to which they should be striving, and contributing to, as scholars and as citizens. However, they are often not given the space-and the challenge-to grapple with what social justice means to, and for, them. This paper shares the design of an upper level sociological theory assignment, Socialization as an Investigation of Social Justice Response Papers, that aims to do just that. The course units and theoretical texts are detailed, along with the response paper scaffold assignments, with special emphasis on a structured peer review process aligned with the assignment rubric. Now, having taught the course eight times to date, memorable student contributions to the course, along with an excerpt from the most memorable student response paper, are shared with the aim of inspiring faculty modification, particularly in the Social Sciences.
Legal collisions in the legislative and regulatory act that affect the professional level of police officers and the trust of the police in society
Authors: Velykyi Yuriy
Published: January 2022

The article attempted to scientific substantiate the gaps in the Government Draft Law No. 2822 "On the National Police", which on May 21, 2015 supported in the first reading the Verkhovna Rada of Ukraine and prepared on the basis of Article 75 of this Law of the by-law "police" normative legal act - Regulations on the organization of postgraduate education of employees of the National Police, approved by the Order of the Ministry of Internal Affairs of Ukraine of December 24, 2015 No. 1625 [2, 3]. A detailed analysis of the above-mentioned legislative and "police" normative legal act allowed to trace the contradictions that arise during their implementation, the existence of legal collisions between the Law of Ukraine "On the National Police" and a by-law norm that affects the professional level of police officers. The article provides a scientific justification for the feasibility of reforming at the present stage of society one of the most important types of professional training of police officers, defined by the Law of Ukraine "On the National Police", postgraduate education, which should be carried out in higher education institutions with specific conditions of training and at the place of their service of the police officer. The conducted study requires the heads of territorial bodies of the National Police to pay attention to the existing shortcomings in the state of postgraduate education, as they are customers of training subordinates in higher education institutions with specific conditions of study. In order to increase the level of public trust in the police, heads of all levels must monitor and create the necessary conditions for improving the professional level of police officers.
The communicative competence of the National Police: current challenges in the context of quarantine measures during a pandemic
Authors: Shinkarenko Inna
Published: January 2022

The paper emphasizes that communication skills become a priority among the most important qualities that a National Police officer should possess. The article emphasizes that this is especially true during period of quarantine measures, when the level of anxiety of the population increases. As a result, there are certain psychological barriers to communication that a National Police officer must avoid and overcome when necessary. These are logical, stylistic, semantic and phonetic barriers. The research determines that the mask mode also makes special demands on communication, both verbal and nonverbal aspects. The article focuses attention on the fact that during the period of quarantine measures, special requirements are placed on police officers when choosing and maintaining the area and distance of communication. After all, traditional rules are violated so as not to endanger both citizens and the policeman himself. Due to the tense situation during the COVID-19 pandemic and the special emotional state of citizens, law enforcement officers must have an arsenal of skills to relieve stress with the help of language, be correct, restrain emotions, even under mental stress. The article notes that during the quarantine there is an increase in cases of domestic violence because of forced isolation, economic problems, and lack of personal space of family members. Thus, in order to resolve family and domestic conflicts, a police officer must have not only communicative but also conflictological competence. The paper provides practical recommendations for the peaceful settlement of conflicts, identifies methods of communicative influence on people, and lists the main psychotechnics of influence. Thus, the communicative competence of police officers depends not only on stabilizing the situation during a pandemic, not only on public order and the criminal situation, but also on increasing public confidence in the activities of the state and state institutions represented by law enforcement agencies.
La mirada reflexiva, aportaciones epistemológicas al periodismo literario ante el espejismo del metarrelato de la era digital
Authors: Gayà Morlà Catalina , Garde Cristina , Seró Moreno Laia
Published: February 2022

Este ensayo propone reflexionar en torno a los aportes epistemológicos que la etnografía hace al periodismo literario. El objetivo es incorporar a la discusión en torno al periodismo literario la mirada reflexiva. Se argumenta que un periodismo basado en una mirada reflexiva es un ejercicio participativo en el que los sujetos, mediante un ejercicio de intersubjetividad, intentan interpretar, narrar y crear un mundo común. El ejercicio es dialógico y es fruto de una escucha activa y de la asunción de que la periodista no es ni pasiva ni externa a aquello que vive y narra. La propuesta cambia radicalmente las lógicas de la hipersimulación: permite a la comunidad apropiarse del aquí y ahora y abandonar el presente continuo. En el texto se expone que es función del periodismo literario ser una alternativa al metarrelato del capitalismo acelerado de la era digital y de poner en evidencia el espejismo que construye el capitalismo en las plataformas. La mirada reflexiva ofrece el marco epistemológico para hacerlo.

Published: February 2022

La investigación se focaliza en el miedo a hablar en público, o glosofobia, de los estudiantes de postgrado en España. El objetivo principal es evaluar los niveles de glosofobia de este colectivo, con especial atención en la oratoria on line. La COVID-19 ha obligado a la realización on-line de múltiples actividades académicas, entre ellas las defensas de TFM. El artículo presenta los resultados de una investigación mixta (cualitativa-cuantitativa) sobre el colectivo estudiantil realizada en la época de presentación de su TFM. Previamente una quincena de expertos validó el cuestionario. El coeficiente Alfa de Cronbach fue de 0,82. Entre las principales conclusiones destaca la necesidad de introducir una formación específica en oratoria en el currículo de los programas de postgrado con especial énfasis en las interacciones on line. Se ha demostrado que la glosofobia es transversal y afecta a cualquier tipo de estudiantes. Esta propuesta es inexistente en España.

Authors: Zharkovskiy A. A. , Shchur V. A. , Omran M. , Staseyev A. A.
Published: January 2022

The article describes approaches to the design of a vane system of radial-axial hydraulic turbines based on an automated design system developed at SPbPU using the Python programming language. The specified system currently includes the following modules: selection of the main parameters of the hydraulic turbine, construction of the meridional projection of the impeller, calculation of the potential flow and construction of the blade system of the radial-axial hydraulic turbine. The choice of the main parameters of the hydraulic turbine is based on the technique generally accepted in hydraulic turbine engineering, which has been digitized and introduced into the software package. The paper considers and analyzes different approaches to the design of the meridional bypasses of the flow path in the area of the impeller of a radial-axial hydraulic turbine, a comparison of the results of their construction using different methods is given. A technique that is most suitable for algorithmization in the software package based on the results of the analysis was selected. The construction of streamlines and the calculation of velocities along them are presented on the basis of the calculation of the potential flow in the meridian section. The design of the blade system of the hydraulic turbine was carried out by the method of solving the direct axisymmetric problem of the theory of hydraulic machines. As an example, a blade system of a radial-axial hydraulic turbine was designed for a head up to 75 meters, the initial parameters of which correspond to hydraulic turbines-analogues of similar speed. The designed hydro turbine was calculated in Ansys, and the results confirmed its excellent energy properties. It is planned to further develop the software package in terms of automatic construction of 3-dimensional solid models of the flow path, which can later be calculated by the methods of computational fluid dynamics and optimized to obtain hydraulic turbines with parameters corresponding to the current state of the art.
Numerical simulation of cavitation in the flow path of a reversible hydraulic machine for a head up to 250m
Authors: Seleznev V. N.
Published: January 2022

In areas where thermal and nuclear power plants are mainly located, the problem of lack of maneuverable capacities, the coverage of peak loads and the passage of periods of reduced energy consumption is solved through the construction of large pumped storage power plants (PSPP). To create highly efficient flow paths for pump-turbines, one of the modern trends is the use of numerical modeling of three-dimensional fluid flow. Nowadays, there are many software products that implement numerical modeling by the finite volume method. The most famous among them are Fluent, CFX, StarCD, Numeca, Flow Vision and CADRUN. Verification of the computational model remains an urgent task. It is important to choose a methodology that will allow you to get an acceptable result with optimal time spent on preparing data and conducting computational studies.

The article examines the flow path of a radial-axial pump-turbine designed for use at a maximum head up to 250m. Numerical modeling of the cavitation process arising in the turbine mode at a significant distance from the optimum of the characteristic was carried out. The calculations were performed using the Ansys CFX software package, version 2021R1. A brief description of the problem statement, the computational grids used and the assumptions made is given. Comparison of calculation results with experimental data is presented. A qualitative comparison of the cavitation origination regions obtained by numerical simulation with the data of monitoring the state of the base metal and welded joints of the hydroelectric unit impeller by the method of non-destructive testing is carried out.

The aim of the work was to present an economical technique for numerical simulation of cavitation to determine the places of possible occurrence of cavitation wear. The technique consists in describing the formulation of the problem, the computational grids used and the assumptions made for the optimal use of computing resources without a significant loss in the accuracy of the results.

Published: January 2022

The work is devoted to the operation of an automobile differential of suspended friction modeling in the system for calculating the dynamics of coupled bodies. The model was developed in the RecurDyn application for calculating the dynamics of rigid and deformable bodies from the FunctionBay company.

The aim of the work is to develop a mathematical model of the differential with friction washers and to confirm the adequacy of its operation. The developed mathematical model of the differential is tested for the possibility of its subsequent use in modeling the transmission of a vehicle in the calculating the dynamics of coupled bodies system. In this work, a model of the differential has been created and described in detail. The model was used for the analysis of kinematics and dynamics. Methods of modeling a simple symmetric differential and a self-locking one are shown based on one mathematical model. The well-known analytical dependences describing the kinematic and force laws of the ratio of angular velocities and torques between the output links and the differential housing are given. A method for calculating and modeling the friction torque in the differential was selected and described. An equation describing the frictional moment in the differential is presented.

A virtual test bench was developed and described. Afterwards it was used for differential operation simulation. Load modes that are equivalent to various driving conditions of a real automobile are selected, their quantitative parameters are given. In this work, the criteria for evaluating the performance of the differential model are selected. The results of modeling for all load modes are given. According to those results the adequacy of the developed mathematical model of the differential with friction washers is proved. The proposals on the use of the developed model are given.
Study of existing designs of the peristaltic principle pumps

Peristaltic pumps are used in a wide variety of applications due to their tightness, ease of maintenance and accurate delivery. Nevertheless, the use of peristaltic pumps is limited by their disadvantages: short service life of the working body and uneven feed. This work provides an overview of the existing design solutions for pumps. The main advantages and disadvantages of the most common modern designs of peristaltic pumps are considered. The developed design solutions are presented. These solutions are designed to extend the service life of the elastic working body of the pump. These include a spiral hose design, where hose life is improved by reducing the number of cyclic compressions using just one roller. Another solution is to operate the pump with incomplete compression of the working element, which reduces the stress values and thereby prolongs the service life of the working element. The special shapes of protrusions in the compression area were developed in order to compensate the decrease in flow caused by the operation of the pump with incomplete compression of the working member. The paper provides an overview of solutions to reduce the uneven flow of a peristaltic pump. The simplest of these is the use of multiple parallel channels. In other designs, the elimination of flow pulsations is achieved with a pneumatic damper. There is also a constructive solution, in which a special algorithm of actuation of five squeeze elements is used for uniform supply, each of which compresses only its own section of the pump working body. Based on the analysis, it is shown that in order to eliminate the disadvantages of peristaltic pumps the various methods are used. Nevertheless, those methods need further improvement.
Bürokratiekritik in der öffentlichen und veröffentlichten Meinung: Impulse für Verwaltungsreformen?
Authors: Grunow Dieter , Strüngmann Daniela
Published: February 2022

Der Beitrag stellt neuere empirische Untersuchungen zur Wahrnehmung und Bewertung der öffentlichen Verwaltung durch die BürgerInnen und zur diesbezüglichen Berichterstattung der Printmedien vor. Dabei wird zunächst gezeigt, dass die Bevölkerungsreaktionen nicht nur insgesamt ambivalent ausfallen, sondern dass auch die einzelnen Befragten Meinungs-Dissonanzen aufweisen, bei denen dezidierte Bürokratiekritik mit positiven Beschreibungen persönlicher Erfahrungen einhergehen. Dies führt zur Frage nach der potenziellen Bedeutung der Printmedien bei der Erzeugung von Urteilen und insbesondere von negativen Stereotypen über die öffentliche Verwaltung. Es kann gezeigt werden, dass es eine breite Berichterstattung gibt und dass diese überwiegend kritisch ausfällt. Da belegbar ist, dass die empirischen Daten ein – auch von der Verwaltungsmodernisierung kaum beeinflusstes – Dauerphänomen beschreiben, wird abschließend nach den Funktionen und Folgen dieses als „perpetuum mobile“ bezeichnetes Phänomen für das politisch-administrative System gefragt. In Form einer Thesensammlung wird der Prozess als dauerhafter Antriebsmotor für Reformen der bürgerbezogenen Verwaltungsarchitekturen skizziert.
Logik des Scheiterns oder Scheitern an der Logik? (Kommentar zu Lars Holtkamp „Das Scheitern des Neuen Steuerungsmodells“)
Authors: Banner Gerhard
Published: February 2022

Eine modernisierte „post-weberianische“ Kommunalverwaltung muss sich von der Behörde zum Dienstleistungsunternehmen wandeln. Das war explizit die zentrale Botschaft des NSM. Lars Holtkamp blendet sie aus und unterstellt, das Hauptziel des NSM sei die Haushaltskonsolidierung (Einsparungen) gewesen. Dieses Ziel sei verfehlt worden. Es sei auch von vornherein nicht erreichbar gewesen, da die „Standardinteressen“ mächtiger Akteure an der Ausweitung ihrer Etats dies zwangsläufig verhinderten. Somit sei das NSM gescheitert. Holtkamps Argumente halten einer Nachprüfung weder empirisch noch logisch stand. Er blendet unter anderem aus, dass das auf dem Ressourcenverbrauchskonzept basierende neue kommunale Haushaltsrecht – ein spin-off des NSM - der Implementierung wesentlicher Elemente der organisatorischen Infrastruktur des NSM wie Budgetierung, Ziele, Kennzahlen, Kontraktmanagement, Kosten- und Leistungsrechnung neuen Schub gibt.
