Authors: Benhacine Tarek Zine-eddine , Mouzai Abdelmadjid , Azaz Aimen Azedin , Boudraf Mustapha
Published: September 2024

A wind turbine emulator is a valuable tool, which enables real-time physical simulation of a wind turbine behavior using a dedicated experimental test setup, providing a controlled environment for research and development purposes. One significant advantage of using this tool is its ability to test control algorithms designed to maximize power extraction from the wind turbine. This paper continues previous work on developing a small-scale variable-speed wind turbine emulator based on a Permanent Magnet Synchronous Generator for stand-alone applications (Benhacine et al., 2024). This paper presents enhancements made to the emulator. These improvements facilitate the assessment of a maximum power point tracking control strategy designed to optimize power extraction from the wind turbine.

Authors: Kunjumon Mekha , Babu Libina , Boss Aswathy
Published: September 2024

Microfluidics technology is a promising method for creating advanced drug delivery systems, particularly in cancer detection and treatment. These systems provide accurate, efficient, and user-friendly methods for cancer detection and treatment by examining small samples. Microfluidic devices can produce nanoparticles for medication administration and identify cancer-diagnostic variables from biological fluids. Due to their high sensitivity, high throughput, and low cost, microfluidics may be useful in cancer study. While not currently used in clinical settings, microfluidic systems are expected to replace current technologies as the primary means of cancer diagnosis and treatment. Microfluidic lab-on-a-chip platforms have shown potential in designing novel procedures for cancer detection, therapy, and disease follow-up, as well as developing new drug delivery systems for cancer treatment. They are also being considered a rising method in natural disease studies due to their small volume and ability to be used in clinical settings.[1,2.3] Keywords: Microfluidics, detection, treatment
A képviselô-jelölési rendszer problematikája a két háború közötti közjogi szakíróink munkáiban
Authors: Hollósi Gábor
Published: September 2024

Témánk feldolgozásánál abból indultunk ki, hogy a Horthy-korszak országgyűlési választásai köré csoportosítottuk időrendben az általunk legfontosabbnak vélt korabeli közjogi szerzők tanulmányunk tárgyát érintő főbb munkáit, egyes esetekben ugyanazon mű átdolgozott kiadásait. Így mutatjuk be azt, hogy miként formálódott a képviselő-jelölési rendszer kritikája a két háború közöttiközjogi szakirodalomban a választások hatása alatt. Módszerünkben azonban nem lehettünk egészen következetesek, hiszen az 1935. évi választásokat követően már nem a fennálló rendszer, hanem az új választójogi törvény javaslatának kritikái a lényegesebbek. Továbbá, mert az 1939. évi választás volt az utolsó általános országgyűlési választás a korszakban, célszerűnek tűnt, hogy ezzelcsak lazább összefüggésben foglaljuk össze az 1938. évi választójogi törvény jelölési rendszerét illető megállapításokat. Mindenekelőtt azonban azt tartottuk fontosnak, hogy egy önálló fejezetbe gyűjtsük ki a korabeli szerzők munkáiból – megjelenésük időpontjára tekintet nélkül – a képviselő-jelölés mibenlétére vonatkozó „dogmatikai” álláspontokat. A kapcsolódó jogszabályi rendelkezéseket tanulmányunkban csak szükség szerint ismertetjük, mivel korábban azt már megtettük.

Az első világháború kitörése Franciaország bevándorlási politikájában is éles határvonalat húzott. A hadviselő felek 1914 nyarán egyszerre szembesültek a tömeghadseregek által vívott harcok kihívásaival a frontokon és a hátországban. Az előzetes várakozások ellenére elhúzódó harcokban pedig a hadvezetés mellett legalább annyira vagy még fontosabbá vált a hadsereget kiszolgáló ipari termelés folyamatosságának megszervezése. Ebben jutott szerephez a gyarmati munkaerő.
A fiatalkorúak büntethetôségének történeti szempontú vizsgálata
Authors: Herke-Fábos Barbara Katalin
Published: September 2024

Az életkor és a büntethetőség szubjektív kategóriáinak (beszámítási és belátási képesség) vizsgálata jelöli ki a gyermek- illetve fiatalkorúval szemben alkalmazott felelősségre vonási eljárás színterét és határozza meg a kezelési lehetőségeket. Tehát a téma teljeskörű feldolgozása nemcsak anyagi jogi megközelítést, hanem eljárásjogi szemléletet és büntetés-végrehajtási, valamint kriminológiai ismereteket is igényel. A kérdéskör kapcsolódik a büntető igazságszolgáltatás valamennyi területéhez. A tanulmány címét szem előtt tartva azonban terjedelmi okokból elsősorban a büntető anyagi jogi szempontok kibontására törekszünk. Az anyagi jogi vizsgálatot a bűnelkövető gyermek fogalmi lehatárolásából eredeztetjük. A tanulmányt átható történeti szempontú megközelítésselarra vállalkozunk, hogy bemutassuk a hatályos szabályozás mögött meghúzódó normatív és jogelméleti hátteret.
A semlegesség nemzetközi jogi fogalma és Magyarország második világháborús külpolitikai törekvéseinek jogtörténeti megközelítése a semlegesség tükrében I.
Authors: Kui Gábor
Published: September 2024

Szinte lehetetlen úgy írni a háborúról vagy a háborúhoz kapcsolódó jogi fogalmakról, hogy annak ne legyen szomorú aktualitása. Nem sok olyan időszak volt az emberiség történetében, amikor ne dúlt volna valahol háború. Nehéz is lett volna elkerülni ezeket az összetűzéseket, hiszen az államokat a nemzetközi jog fejlődése során egészen a 20. századig megillette a háború indításához való jog, a ius ad bellum. Az államok közötti konfliktusok elsődleges megoldási módszere a háború volt. Az emberi leleményesség és a technika fejlődésével a harcok egyre kegyetlenebbek, egyre embertelenebbek lettek, és egyre több ember életét követelték. Csupán a 19. században kezdődött el az a folyamat, amely a háború pusztításainak enyhítésére tett kísérletet. Ma már természetesen nem illeti meg az államokat a háborúhoz való jog sem, ennek megsértése is komoly nemzetközi jogsértésnek minősül.
Bepillantás a gyermekeket érintô legjellemzôbb polgári perekbe Szabolcs vármegyében (1806–1848)
Authors: Zsírosné László Lívia
Published: September 2024

A magyar államterület igazgatására tipikusan a vármegyék szolgáltak több száz éven át, amelyeknek kialakítását Szent Istvánnak tulajdonítja törvény és hagyomány egyaránt. Két fejlődési szakasz különböztethető meg a vármegyéknél: a királyi vármegye és anemesi vármegye. Az előbbieket az államalapítástól számítjuk az 1200-as évek második feléig, míg az utóbbiak a 13. század második felétől 1867-ig működtek. A királyi vármegyék a feudális magyar állam középszintű igazgatási egységei voltak. Elsődlegesen a központi akaratot közvetítették helyi szintre.
A törvénytelen gyermek jogállása: szabályozások a 20. század elején
Authors: Kasuba Róbert István
Published: September 2024

A magyar történelem szinte minden szakaszában jelentős kérdés volt az, hogy a családban született gyermek a férj és a feleség nemi kapcsolatából származzék. Ezt a fontos kitételt képviseli a mai napig a kánonjog, és képviselte az 1950-es évekig a magyar állami jog is. Ez azt jelenti, hogy évszázadokon át csak az a gyermek rendelkezett cselekvőképességgel, örökölhette apja rangját, nevét és vagyonát, aki törvényes volt, tehát a férj és a feleség érvényesen megkötött házasságából származott. A nem ilyen kapcsolatból származó gyermeket törvénytelennek tekintették, aki csak anyja nevét viselhette, és semmilyen jogi kapcsolatba nem kerülhetett biológiai apjával és annak családjával. A nemesi családokban nagyon fontos szempont volt, hogy a gyermek tiszta kapcsolatból születhessen, hiszen a név és a rang továbböröklésére csak az a gyermek volt jogosult, aki szüleinek törvényes gyermeke volt. Ez nem azt jelenti, hogy ezekben a családokban nem voltak jelen házasságon kívüli kapcsolatok, amelyekből esetlegesen gyermek is származott. A polgári családok életében is jelentős volt a családi vagyon öröklése szempontjából a név tisztaságának kérdése. A legtöbb törvénytelen gyermek olyan kapcsolatból született, ahol az anya (vagy esetleg az apa) hatalmi viszonyban állt az apával (esetleg az anyával). Ilyenek voltak a háztartási alkalmazottak, cselédek, gyári és mezőgazdasági munkásnők, de az is előfordulhatott, hogy egy munkáslegény csábította el a gazda lányát, vagy a jómódú polgárcsalád leányát. A törvénytelen születés esetében előfordult az is, hogy az anya állami gondoskodásba adta gyermekét, hiszen egy gyerekkel nem lehetett ismét elmenni szolgálni vagy dolgozni. Az is megoldás lehetett, hogy az anyai nagyszülők nevelték a gyermeket, az anya pedig a tartásról gondoskodott munkájával. Ezen kívül a törvénytelen gyermekek körében nagyobb volt a csecsemő- és gyermekhalandóság aránya az általában rosszabb gondozási, nevelési körülmények miatt, legalábbis Budapest tekintetében. Tanulmányomban azt a kérdést szeretném megvizsgálni, hogy hogyan alakult a törvénytelen gyermek jogi sorsa az 1928. évi magánjogi törvényjavaslat (Mtj.) megalkotásától kezdődően 1946-ig, a kérdés végleges rendezéséig.

Hybrid Bee Colony Algorithm with Whale Algorithm
Authors: Basim Radhwan
Published: September 2024

In this research paper, two hybrid algorithms of Meta-Heuristic algorithms, both of which are inspired by nature, are presented: the Bee- settlement Amendment algorithm (BCO) and the Whale Amendment Algorithm (WOA). The Bee settlement Amendment algorithm is an amendment algorithm founded on swarm intelligence modeling attitude. It is one of the techniques of synthetic information that focuses on studying the grouping conduct of decentralized systems, which are represented by groups of modest elements that react locally simultaneously and with the surrounding perimeter. One of the methods that distinguishes it is the method of exploration. As for the Whale Amendment Algorithm, whom represents the friendly conduct of the hump-back whale. It is based on the fancy net fishing design. One of the advantages of this algorithm depends on the poise between screening and utilization and avoidance of falling into local solutions. A hybridization process was carried out between the two algorithms, and the new algorithm was named (ABCWOA), and the whole algorithm was used to 16 rising -measurement Amendment assignment with diverse frequencies between (100, 200, 500, and 1000). The outcomes of the proposition algorithm showed access to optimality solutions by achieving the minimum value (f_min). For most assignment, the outcomes of this algorithm were disparity with the search algorithms.

In aquaculture, balanced feed accounts for 50% to 70% of the operational costs of cultivating aquatic organisms. This feed is made from various raw materials that serve as protein sources, which significantly influence the final cost of the feed. Therefore, an electrophoretic study was conducted to compare the protein content in different raw materials and commercial diets used in animal feed. Electrophoretic profiles with standard concentration gels (SDS-PAGE) were used to separate protein fractions from animal-origin raw materials, including Earthworm Meals of Eisenia andrei (HLF) and Eisenia fetida (HLT), meat-bone meal (MBM), and fish meal (FM), as well as plant-origin meals, such as Leucaena leaf meal (LLM), corn meal (YCM), and wheat bran (WBM). Commercial diets (A, B, and C) were also evaluated. The protein content of the samples was determined. For electrophoretic analysis, a protease inhibitor cocktail was used, along with a molecular weight standard with a range from 250 to 4 kDa. The molecular weights of the diets ranged between 31.1 and 234.1 kDa, 36.3 and 190.4 kDa, and 4.281 and 95.685 kDa. Some of the protein bands in the analyzed samples (HLF, HLT, FM, YCM, and WBM) were very close to the reference protein bands at 148, 98, 64, 50, and 36 kDa, corresponding to the molecular weight standard used. Electrophoretic characterization provided insight into the different protein fractions, offering valuable information about their potential functional and nutritional properties. Electrophoresis is an essential analytical tool for assessing both the quality and safety of raw materials and foods.

Authors: Zongyu Yao , Chienwattanasook Krisada
Published: September 2024

For Chinese university lecturers, implementing sustainable human resource management (SHRM) is particularly critical. China's higher education is going through an essential stage of appointment system reform aiming to overturn the traditional civil service status of university lecturers and introduce a more flexible work and talent management mechanism to universities to international teaching standards; lecturers also raise concerns about their professional role, educational mission, balance of rights and interests, and the reshaping of the evaluation system. Based on the resource-based perspective and psychological contract theory, this study aimed to explore the relationship between sustainable human resource management (SHRM) and lecturers' professional identity in the context of China's appointment system, focusing on analyzing the moderating role of lecturers' self-efficacy. This study used a quantitative research approach to collect survey data from 610 lecturers at public colleges and universities in China. The data were analyzed with a structural equation model to test the hypothesized relationships. SHRM was directly and positively related to lecturers' self-efficacy and sense of professional identity and indirectly improved sense of professional identity by enhancing self-efficacy. The findings are consistent with existing literature, emphasize the importance of SHRM in promoting lecturers' career development, and provide empirical support for applying SHRM in the context of Chinese higher education. The study provides recommendations in three dimensions: Government, University, and Faculty. It provides guidance for strategic reform of human resource management in higher education, faculty career development, and improving education quality.

Financial liberalization is a widely adopted policy for countries to enhance growth. Financial liberalization enables financial institutions to proceed with innovative activities by familiarizing themselves with fewer mortgage loans in the financial market. Financial liberalization is a widely adopted policy for countries to enhance growth; however, it is a complex and controversial issue, with different studies providing contrasting perspectives. Financial liberalization is considered an efficient way to measure and change the financial market and structure in order to reach a position to get financial liberalized markets under an efficient and effective guideline. In the case of Vietnam, very few scholars have investigated the issue of financial liberalization-led growth. This endeavor examines the effects of financial liberalization on economic growth in the presence of control variables for Vietnam over the period of 1990 to 2021. This study uses the Autoregressive Distributive Lag Model approach due to its several advantages. The results show that financial liberalization enhances economic growth, which implies that more liberalization results in enhanced growth in Vietnam. Improved access to credit is another positive outcome of financial liberalization, as it can result in greater access to credit for individuals and businesses, enabling them to make investments and expand their operations. Hence, the results support the neo-liberal view of liberalization.

Social media’s pervasive influence extends to the agricultural sector, driving transformative changes. The purpose of this study aims to comprehensively overview how different generations of Thai farmers utilize social media. It has two principal objectives: first, to explore farmers’ behavior in relation to the frequency of social media use, their preferred platforms, and engaging advertising formats; and second, to examine the correlation between different generations of farmers and their choice of social media platforms. The study employed purposive sampling and quantitative methodologies to survey Thai farmers, utilizing questionnaires for data collection and analyzing the data with descriptive statistics. A total of 150 participants took part, evenly distributed across rice cultivation, gardening, and arable crop cultivation. The findings of this study showed that social media platform usage among farmers was found to vary by generation, with each cohort demonstrating distinct preferences for different platforms. It was observed that older generations, such as Baby Boomers and Gen X, tended to concentrate their social media usage on a select few platforms, while younger generations, including Gen Y and Gen Z, exhibited more diversified usage patterns. Therefore, understanding generational differences in social media platform usage among farmers remains crucial for developing targeted communication strategies, facilitating knowledge dissemination, and enhancing market engagement within the agricultural sector. Encouraging the utilization of social media in agricultural promotion initiatives maximizes benefits for farmers and aids in adapting to the changing landscape of the agricultural industry in Thailand in the digital era.

Authors: Nam SangHun
Published: September 2024

This study investigated the application and acceptance of virtual reality (VR) and mixed reality (MR) technologies in university education. Here, university freshmen were introduced to these technologies and surveyed to assess their perceptions of VR and MR systems when applied in educational settings. The results demonstrate that the participants generally responded positively to both technologies, with VR being rated higher in terms of enjoyment and perceived usefulness. The findings suggest that students are more inclined to use VR in future educational settings. MR also received favorable evaluations; however, it received lower evaluations, particularly in terms of ease of use, which is likely due to the participants’ relative inexperience with the technology. The findings of this study highlight the potential of VR and MR technologies as effective educational tools and emphasize the importance of leveraging their respective advantages.

Published: September 2024

This study analyzes the limitations of silicone molds used for free-form panel production and aims to address these issues by utilizing paraffin wax. Silicone molds are known for their reusability and ease of forming free-form shapes. However, the lack of a fixing method between the side and bottom molds makes them vulnerable to lateral pressure. Through FCP production experiments, 3D scans were conducted and shape errors were analyzed. The results showed that while the overall errors were uniform, errors exceeding 3 mm were observed at both ends of the curved sections. These errors are attributed to the installation of CNC equipment and the assembly process of the molds. Therefore, future research should focus on refining the corners and joints of the molds as well as validating complex curved shapes. This study is expected to serve as foundational data for research related to free-form molds.

Physical properties of cement composite with monoethanolamine
Authors: Lee Sangsoo , Jeon Eunyeong , Lee Jeongtaek
Published: September 2024

This study analyzed the fluidity, air content, flexural strength, compressive strength and carbon dioxide adsorption performance of cement, furnace slag and fly ash-based cement composite using appropriate substitution values of MEA derived from preliminary experiments. Fluidity and air content were found to increase as the fly ash substitution rate increases. It is believed that the increases are due to the fly ash ball bearing effect in combination with the creation of micropores by MEA. The compressive strength was found to decrease with lower furnace slag substitution ratios. This is believed to have resulted because the Pozzolanic reaction of the fly ash plays a more dominant role in determining the compressive strength than does the latent hydraulic activity of furnace slag as the furnace slag substitution rate is decreased. It is determined that the compressive strength was reduced because the Pozzolanic reaction reduces the density of the texture and pore structure of the interfacial transition zone. Carbon dioxide values increase as the furnace slag substitution rate was increased.

Published: September 2024

Developing a hydrogen leak detection system that can quickly detect even the smallest amount of hydrogen is extremely crucial in the hydrogen industry. Currently, hydrogen refueling stations use a fixed hydrogen leak detection system. This study develops a mobile hydrogen gas leak detection system for hydrogen refueling stations using s, global positioning system, and Internet of Things (IoT) equipment, including LoRa and Wi-Fi. A digital twin is implemented by linking hydrogen gas-sensing data at a location that is quickly required or suspected using Google Maps. A time-series database is used to store the hydrogen gas-sensing data, and the transfer delay of hydrogen gas-sensing data between the hydrogen equipment was measured. Therefore, we developed a prototype system that transmits, stores, and analyzes hydrogen gas-sensing data in real time using IoT equipment for hydrogen refueling stations.

Authors: Jeong Hyunsu , Jeon Eunyeong , Lee Jeongtaek , Lee Sangsoo
Published: September 2024

This study analyzes the properties of cement mortar according to the substitution of fine ferro-nickel slag powder in various types of fine aggregate, with the aim of recycling industrial waste. When using a ferro-nickel slag powder as the admixture of cement mortar, it is determined that substitution rates of 30% and higher are unsuitable for use as mortar. In order to solve this problem, it is believed that it is necessary to explore means to improve the initial strength degradation that results when fine ferro-nickel slag powder is mixed. Furthermore, the differences in carbon dioxide reduction according to fine ferro-nickel slag powder substitution rates were found to be minimal, and it is thought that additional performance analysis is necessary.

Authors: Lee Do-Young , Noh Gie-Ok
Published: September 2024

This study was conducted in two stages, the tool development stage and the tool verification stage, and was based on DeVellis' tool development guidelines. A total of 18 questions were confirmed as a result of developing a successful aging measurement tool for middle-aged women and verifying the validity. It consisted of a total of 5 factors, and in consideration of the characteristics of the items included in each factor, factor 1 was named 'inconvenience of aging', factor 2 was named 'inconvenience of female hormone deficiency', factor 3 was named 'family success', factor 4 was named 'appearance due to aging', and factor 5 was named 'aging and lifestyle change'. It is measured on a 5-point Likert scale, and the score is 18 points to 90 points, which means that the higher the score, the higher the successful aging. The tool developed in this study will be used to measure successful aging status tailored to middle-aged women.
The relationship between cervical lordosis and neck pain: a systematic review and meta-analysis
Authors: Kim Kyung-Ho , Park Seong-Ah , An Chang-Sik , Kim Jeong-Lae
Published: September 2024

: The interpretation of the correlation between cervical lordotic angle (CLA) and neck pain (NP) among clinicians remains contentious, reflecting the nuanced nature of this association within clinical discourse. This relationship assumes paramount importance in clinical practice, as it serves as the cornerstone for devising effective therapeutic strategies aimed at the management and prevention of NP. The objective of this study was to determine the difference in CLA between individuals with and without NP. The inclusion criteria entailed observational studies rigorously evaluating CLA through radiological imaging in both NP patients and healthy controls (HC), while pediatric, geriatric populations, and non-degenerative spinal conditions were excluded. We conducted a thorough electronic search across several databases including Medline, Cochrane Library, Embase, CINAHL, and PEDro. The search strategy employed terms pertinent to cervical alignment and NP, using Boolean logic. Specifically, search terms such as "neck pain*", "cervical pain*", and "lordo*" were used to ensure comprehensive coverage of relevant literature. We estimated the standardized Mean Differences (SMD) and their corresponding 95% Confidence Intervals (CI). Additionally, chi-square and I2 statistics were used to evaluate within-group heterogeneity through a random effects model. A total of 6 studies, involving 436 patients with NP and 491 HC, were identified. Overall, individuals with NP demonstrated a tendency towards smaller CLA compared to the HC group.

Authors: Chenglong Dai , Khiatthong Thongchue
Published: September 2024

Restoration of rural art museums in southern Zhejiang is important for regional and national development. Therefore, this study focuses on the strategic management issues of rural art museums in southern Zhejiang in the context of revitalization. This research sets three objectives: (1) to study and analyze rural art museums; (2) to synthesize strategic management; and (3) to create, propose, and define strategic management. This study used a mixed approach, with 300 stakeholders from five rural art museums in southern Zhejiang. The results show that elements of the strategic management model for rural art museums in southern Zhejiang Province can be determined. From the second objective, it is possible to formulate and implement a strategic management model in accordance with empirical data. An operational manual was developed and divided into 15 items for the strategic management of rural art museums that could be adapted to the southern region of Zhejiang Province. However, based on the questionnaires, in-depth interviews, and field visits, the average satisfaction with the level of rural art museum management was 3.27, with a standard deviation of 1.32. The average satisfaction score for the exhibition was 3.27 with a standard deviation of 1.38. Similarly, the average overall satisfaction with rural art museum was 3.4 with a standard deviation of 1.23. This study provides theoretical support and practical recommendations for strategic management of rural art museums. This study provides valuable insights into rural art museum research across the country. It also opens up new perspectives for the study of regional relations within the academic community and increases the depth and breadth of academic discussions.
The impact of students’ misperceptions on test performance: A 3p model and self-determination theory approach
Authors: Fraidan Abdullah Al
Published: September 2024

This research investigates the complex relationship between students’ misperceptions about their teachers and exams, test anxiety, and their overall test performance, framed through a newly proposed Presage, Process, Product (3P) model and Self-Determination Theory (SDT). Specifically, it explores how students’ misperceptions formed during the presage phase disrupt Basic Psychological Needs (BPN) for autonomy, competence, and relatedness, negatively influencing their test-taking strategies and performance outcomes. The study adopts a theoretical approach, proposing a conceptual framework rather than collecting empirical data, to illustrate the potential dynamics between misperceptions, test anxiety, and academic achievement. A key feature of the new 3P model is the two-way interaction between the process and product phases, illustrating how the test-taking behaviors (process) influenced by misperceptions and anxiety can cyclically affect performance outcomes (product). For example, students who experience anxiety may revisit questions due to self-doubt, changing correct answers to incorrect ones, which further exacerbates their anxiety and harms overall performance. This cyclical interaction highlights the need to break the negative feedback loop to improve test results. By examining the multifaceted impact of pre-test beliefs, such as overconfidence and perceived difficulty, this research offers insights into how these misperceptions affect test performance by fostering anxiety and maladaptive test-taking strategies. The newly proposed PPP model highlights the operational variability of test-taking strategies across different phases, emphasizing the need for teachers to correct students’ misperceptions to enhance performance. This study provides actionable insights for educators to address psychological needs, mitigate anxiety, and promote better academic outcomes. Future research should test the conceptual framework through empirical investigations to further validate its applicability in educational settings.

Organieke wetten: een categorie apart?

Organieke wetten zijn wetten die voortvloeien uit een grondwettelijke opdracht en staatsrechtelijke constituerende regels bevatten. Zij hebben echter juridisch gezien geen andere status of positie dan reguliere wetten. In Frankrijk is dat anders: daar gelden voor organieke wetten andere regels van totstandkoming. In de literatuur is wel bepleit dat organieke wetten ook in Nederland een aparte categorie van wetten zouden moeten zijn. Zij zouden dan grondwettelijke normen kunnen bevatten, die uit de Grondwet worden gehaald. Het is echter de vraag welk probleem dat oplost.
