The Malleus Maleficarum:Rationalism vs.Superstition?

The Malleus Maleficarum(1486)by Henry Institoris and Jacques Sprenger was written in order to help inquisitors identify,persecute,and prosecute witches.The book is well-known but not studied as much as one could think,and is sometimes confused with another treatise written in 1669,which includes works by demonologists,such as Jean Nider,Bernard Basin,and Bartolomeo de Spina.This can be explained by the fact that several successive editions were published,which changed the essence of the first essay,until the 17th century.My argument is that the first edition was paradoxical and not as strict as one could imagine.The book was a“bible”for the inquisition about the subjugation of witches,but in the same way,the book seemed to be far too rationalistic when confronted with satanism and superstition.Indeed,we believe that the thesis of the Malleus Maleficarum was also a new way of conceiving of knowledge,fighting against superstition by using the tools of early rationalism at the end of the 15th century.The witches’knowledge that is investigated in the book is confronted with theology,as well as with reason.There is significant evidence of the writers’rationalistic view about occultism and belief.

Community perspectives on the effectiveness of watershed management institutions in the Himalayas

The sustainability of environmental management initiatives,such as watershed management programs,relies on the presence of effective institutions at the watershed level.However,there needs to be more empirical evidence from evaluating the effectiveness of watershed-level institutions.Therefore,this study presents a pioneering effort to evaluate the effectiveness of Nepal’s first watershed conservation committee at the watershed scale,focusing on the case of the Khageri Khola watershed in Central Nepal.The study involved conducting a household survey,key informant interviews,focus group discussions,and field observations to collect and analyze the data.Descriptive analysis,index value calculation,and chi-square statistics were then employed to summarize the results regarding local respondents’perceptions of twelve institutional characteristics,their rationalities,and their association with socio-demographic variables.The results reveal that the watershed conservation committee was perceived as performing well in managing the watershed.Specifically,good interaction,appropriate scale,technical,environmental,social,organizational,and government rationality were perceived as highly effective,with an average index value of less than 0.36.In contrast,clarity of objectives and economic rationality showed moderate effectiveness,with an average index value ranging from 0.36 to 0.65.However,the results suggested that adaptiveness,compliance capacity,and financial rationality merit increased attention,intending to improve their performance.Further,the results showed the association of socio-demographics with respondents’perceptions of various indicators of institutional characteristics and their rationalities.Therefore,the study provides valuable insights for policymakers,researchers,and development practitioners charged with designing sustainable and effective programs and institutions.To enhance the effectiveness and sustainability of watershed management programs,we recommend establishing a policy-guided institutional mechanism at the watershed scale.This mechanism should be based on various institutional characteristics and rationalities and should consider the extant variability in the socio-demographic and topographic characteristics of the watershed.

Approximate solution of Volterra-Fredholm integral equations using generalized barycentric rational interpolant

It is well-known that interpolation by rational functions results in a more accurate approximation than the polynomials interpolation.However,classical rational interpolation has some deficiencies such as uncontrollable poles and low convergence order.In contrast with the classical rational interpolants,the generalized barycentric rational interpolants which depend linearly on the interpolated values,yield infinite smooth approximation with no poles in real numbers.In this paper,a numerical collocation approach,based on the generalized barycentric rational interpolation and Gaussian quadrature formula,was introduced to approximate the solution of Volterra-Fredholm integral equations.Three types of points in the solution domain are used as interpolation nodes.The obtained numerical results confirm that the barycentric rational interpolants are efficient tools for solving Volterra-Fredholm integral equations.Moreover,integral equations with Runge’s function as an exact solution,no oscillation occurrs in the obtained approximate solutions so that the Runge’s phenomenon is avoided.

Blockchain-Based Key Management Scheme Using Rational Secret Sharing

Traditional blockchain key management schemes store private keys in the same location,which can easily lead to security issues such as a single point of failure.Therefore,decentralized threshold key management schemes have become a research focus for blockchain private key protection.The security of private keys for blockchain user wallet is highly related to user identity authentication and digital asset security.The threshold blockchain private key management schemes based on verifiable secret sharing have made some progress,but these schemes do not consider participants’self-interested behavior,and require trusted nodes to keep private key fragments,resulting in a narrow application scope and low deployment efficiency,which cannot meet the needs of personal wallet private key escrow and recovery in public blockchains.We design a private key management scheme based on rational secret sharing that considers the self-interest of participants in secret sharing protocols,and constrains the behavior of rational participants through reasonable mechanism design,making it more suitable in distributed scenarios such as the public blockchain.The proposed scheme achieves the escrow and recovery of personal wallet private keys without the participation of trusted nodes,and simulate its implementation on smart contracts.Compared to other existing threshold wallet solutions and keymanagement schemes based on password-protected secret sharing(PPSS),the proposed scheme has a wide range of applications,verifiable private key recovery,low communication overhead,higher computational efficiency when users perform one-time multi-key escrow,no need for trusted nodes,and personal rational constraints and anti-collusion attack capabilities.

Scientific principles for accelerating the Sustainable Development Goals

The Sustainable Development Goals(SDGs)are significantly off-course as we reach the midpoint of their 2030 deadline.From a scientific perspective,the critical challenge in achieving the SDGs lies in the need for more scientific principles to understand the complex socio-ecological systems(SES)and their interactions influencing the 17 SDGs.Here,we propose a scientific framework to clarify the common scientific principles and the rational treatment of diversity under these principles.The framework’s core is revealing the complex mechanisms underlying the achievement of each Sustainable Development Goal(SDG)and SDG interactions.Building upon the identified mechanisms,complex SES models can be established,and the implementation of SDGs can be formulated as a multi-objective optimization problem,seeking a compromise in competition between essential costs and desired benefits.Our framework can assist countries,and even the world in accelerating progress towards the SDGs.

Experimental study of core MHD behavior and a novel algorithm for rational surface detection based on profile reflectometry in EAST

Microwave reflectometry is a powerful diagnostic that can measure the density profile and localized turbulence with high spatial and temporal resolution and will be used in ITER,so understanding the influence of plasma perturbations on the reflect signal is important.The characteristics of the reflect signal from profile reflectometry,the time-of-flight(TOF)signal associated with the MHD instabilities,are investigated in EAST.Using a 1D full-wave simulation code by the Finite-DifferenceTime-Domain(FDTD)method,it is well validated that the local density flattening could induce the discontinuity of the simulated TOF signal and an obvious change of reflect amplitude.Experimental TOF signals under different types of MHD instabilities(sawtooth,sawtooth precursors and tearing mode)are studied in detail and show agreement with the simulation.Two new improved algorithms for detecting and localizing the radial positions of the low-order rational surface,the cross-correlation and gradient threshold(CGT)method and the 2D convolutional neural network approach(CNN)are presented for the first time.It is concluded that TOF signal analysis from profile reflectometry can provide a straightforward and localized measurement of the plasma perturbation from the edge to the core simultaneously and may be a complement or correction to the q-profile control,which will be beneficial for the advanced tokamak operation.

Assessing the Efficacy of Wheat-Soybean Based Intercropping System at Different Plant Densities in Bambili, Cameroon

Wheat is one of the most important cereals in the world, serving as a staple for millions globally. In the wake of the geopolitical crisis between Russia and Ukraine, it has become incumbent for many countries to invest in wheat production. Improving cropping systems for wheat production is paramount. Intercropping cereals with legumes has tremendous advantages. Therefore, this study was designed to optimize wheat production by intercropping it with soybean at different densities. Between March and August 2023, a randomized complete block design trial was conducted in Bambili, North West of Cameroon with treatments T1 (wheat monocrop at 200,000 plants ha−1), T2 (soybean monocrop at 250,000 plants ha−1), T3 (200,000 wheat and 125,000 soybean ha−1), T4 (100,000 wheat and 250,000 soybean ha−1), T5 (200,000 wheat and 250,000 soybean ha−1) and T6 (100,000 wheat and 125,000 soybean ha−1). Results revealed that growth parameters of wheat were not significantly influenced by monocrop or intercrop. The yield of wheat was significantly higher in the monocrop than the intercrop treatments, with slight variation amongst the intercrop treatments. Soybean yield was higher in the monocrop than in the intercrop, with no variations amongst the intercrop treatments. Only the land equivalence ratio (LER) for T5 was greater than 1.0. The competitive ratio for T5 was 0.54 for wheat and 1.90 for soybean, comparatively lower than the other monocrop treatments. Intercropping wheat and soybean at 200,000:250,000 ratio is recommended.

Reflections on architectural design education： The return of rationalism in the studio

The design studio environment has remained the same throughout the past century. As the Studio Culture Task Force of the American Institute of Architecture Students （ALAS） （Koch et al., 2006） noted, the ongoing changes in architecture education are not aligned with today＇s fastchanging world, especially in the context of architectural practice. The AlAS analyzed the design studio problem and expressed doubts on the effectiveness of current studio practices in providing adequate design-thinking education. The report indicates that studio culture values project appearance instead of the actual design process. In recent years, similar problems have been the topic of debates in Khartoum. Criticisms are mostly centered on the observation that students show no interest in the design process and tend to focus on form making. As a result, efforts to teach design methods and to restore the balance between creativity and rationality in the design process have failed. The reason is related to the difficulties associated with the implicit nature of conventional design methods. These difficulties, which are common in architecture schools, include the lack of a clearly defined design methodology and the misunderstood role of the systematic approach to design in the studio. Nevertheless, signs of change are gradually emerging, as demonstrated by the global call for change in the studio environment. This call for change indicates a general agreement on the need for the reorientation of architectural design education toward an engaging policy that considers the social responsibility of architects. This study proposes that the route for change is through the return of rationalism in the studio. Since the 1960 s, many writers have recognized the importance of balancing rationality and creativity, which are mutually interdependent, in the design process. From this perspective, the research question is drawn： how can we bridge the gap between the rational and the creative design activities in the design process？ A theory that conceptualizes the idea of knowledge interdependence does not exist. The available design theories, such as rational problem solving and reflective-in-action theory, deal with different aspects of design activity. Both theories fail to describe the integration of the rational and the creative aspects of the design process. Therefore, we propose the integration of the two theories into a new theory called the integrated design paradigm. The proposed theory serves as a theoretical base upon which the interdependence of the rational and the creative phases of the design process can be conceptualized. We aim to bridge the gap between the two design phases by considering research knowledge interdependency as a unifying activity. The first phase is a systematic method involving research, the use of positive theory, and the production of basic principles. The creative practice phase also involves research and focuses on understanding the rational knowledge developed in the systematic phase, including the basic principles and design strategy, as well as on the application of these concepts to the design problem. The Department of Architecture and Urban Planning at the Ethiopian Institute of Technology EiT of Mekelle University （MU） is currently developing a research program in which the development of and reflection on design methods is a key research area. Within this framework, the present study is intends to be an introductory effort to guide future empirical research. The present study aims to describe the design process of architects, and introduces theoretical and technical frameworks. The integrated design paradigm as a system of inquiry within the spatial relationship strategy is framed.

Claude Bernard’s experimental method of head and hand

According to Claude Bernard,each of the sciences investigates different natural phenomena using experimental methods unique to that science,especially experimental medicine.However,Bernard also argued that these sciences share a“common”experimental method that depends on both the“head”and the“hand”.What he accomplished with his common method is to combine both rationalism and empiricism-head and hand,respectively-to undergird the unity of the experimental sciences while maintaining their plurality.Bernard’s experimental method as articulated in terms of the rational head and the empirical hand metaphor is relevant today to the unity of science vs.pluralism debate,as well as to the rationalism vs.empiricism debate and to the hypothesis-driven vs.data-driven science debate-each of which is explored in turn after briefly reconstructing Bernard’s philosophy of experimental medicine.And his metaphor of head and hand provides a means for examining the natural and biomedical sciences as they evolve with regard to specialization.
