This book is a collection of eight in-depth and detailed research papers authored by Dr. Raman K Attri between 1996 to 2005. The book presents early-career scientific work by the author as a scientist at a research organization. The book provides the conceptual background and key electronics and mechanical design principles used in designing sensors and instrumentation systems to measure snow hydrological parameters. The systems discussed in this book can be used to measure snow depth, layer temperature, temperature distribution profile, (...) surface porosity, etc. The snow parameters measured from instruments and sensors discussed in this book are integrated into larger systems and are used in computer-driven models for snow avalanche predictions. The book presents the design challenges and design methods from electronics and instrumentation design point of view. While the book provides essential understanding of analog electronics design and associated mechanical design for snow hydrological sensors, the book also presents the background theoretical and mathematical models from snow hydrology physics that governs this electronics design.

Multi-point Temperature Measurement has always been very important aspect of physical instrumentation mainly in environmental and Industrial application. A multi-point temperature measurement system has been developed to measure temperature at different points simultaneously. This multi-channel system is designed specifically for measuring snow temperature at 28 different points In snow layers and this multi-point data is used in modeling of snow cover. The interfacing of such multi-channel system to Data acquisition system is one of the most critical design aspects, which affect (...) the overall performance of the system. The temperature sensor system and Data Acquisition System may be working satisfactorily when operated independently but total system integrity is absolutely important when these two sub-systems are interfaced together. Further operating conditions in snow causes many performance and reliability issues to be tackled through proper design. This paper discusses the design aspects involved in the interfacing of the multi-channel temperature measurement system with the Data Acquisition System specifically for Snow hydrological applications.

This paper examines some of the key ways in which water is mediated by technology and human artifacts. I show how the modes in which we conceive and experience this vital fluid are affected deeply by the techniques and instruments we use to interact with it. I argue that a notion of the domestication of water enables us to better grasp our relations with the environment given that vast volumes of water are now neither completely natural nor artificial in (...) the conventional senses of the terms. Instead, water is often filtered through an expansive technological network that not merely changes its flows and phenomenal forms but greatly alters or multiplies its meanings. As examples of this process, I investigate the practical engagement with water by the first Western philosopher; the construction of several large hydrological projects; efforts at river management in the aesthetic landscape; and the emergence of bottled water.

As Kant claimed in the Groundwork, and as the idea has been developed by Korsgaard 1997, Bratman 1987, and Broome 2002. This formulation is agnostic on whether reasons for ends derive from our desiring those ends, or from the relation of those ends to things of independent value. However, desire-based theorists may deny, against Hubin 1999, that their theory is a combination of a principle of instrumental transmission and the principle that reasons for ends are provided by desires. Instead, they (...) may say, there is just one principle, a principle of, if you will, instrumental transmutation: if one desires the end, then one has reason to take the means. See the discussion of General Production, in section 8, for a doubt about this. (shrink)

Stanford’s argument against scientific realism focuses on theories, just as many earlier arguments from inconceivability have. However, there are possible arguments against scientific realism involving unconceived (or inconceivable) entities of different types: observations, models, predictions, explanations, methods, instruments, experiments, and values. This paper charts such arguments. In combination, they present the strongest challenge yet to scientific realism.

We appeal to the theory of Bayesian Networks to model different strategies for obtaining confirmation for a hypothesis from experimental test results provided by less than fully reliable instruments. In particular, we consider (i) repeated measurements of a single test consequence of the hypothesis, (ii) measurements of multiple test consequences of the hypothesis, (iii) theoretical support for the reliability of the instrument, and (iv) calibration procedures. We evaluate these strategies on their relative merits under idealized conditions and show some (...) surprising repercussions on the variety-of-evidence thesis and the Duhem-Quine thesis. (shrink)

In psychiatry, pharmacological drugs play an important experimental role in attempts to identify the neurobiological causes of mental disorders. Besides being developed in applied contexts as potential treatments for patients with mental disorders, pharmacological drugs play a crucial role in research contexts as experimental instruments that facilitate the formulation and revision of neurobiological theories of psychopathology. This paper examines the various epistemic functions that pharmacological drugs serve in the discovery, refinement, testing, and elaboration of neurobiological theories of mental disorders. (...) I articulate this thesis with reference to the history of antipsychotic drugs and the evolution of the dopamine hypothesis of schizophrenia in the second half of the twentieth century. I argue that interventions with psychiatric patients through the medium of antipsychotic drugs provide researchers with information and evidence about the neurobiological causes of schizophrenia. This analysis highlights the importance of pharmacological drugs as research tools in the generation of psychiatric knowledge and the dynamic relationship between practical and theoretical contexts in psychiatry.

The idea that the use of instruments in science is theory‐dependent seems to threaten the extent to which the output of those instruments can act as an independent arbiter of theory. This issue is explored by studying an early use of the electron microscope to observe dislocations in crystals. It is shown that this usage did indeed involve the theory of the electron microscope but that, nevertheless, it was possible to argue strongly for the experimental results, the theory (...) of dislocations being tested, and the theory of the instrument, all at the same time.

The Tianqin, often a plucked zither or lute, holds significant cultural and musical heritage in China. The objective of this study is to explore the evolutionary perspectives on the culture of a Chinese folk musical instrument by examining its playing techniques and cultural changes. Conducted in Longzhou County, Guangxi Zhuang Autonomous Region, China, this study involved ethnographic fieldwork, including participant observation and interviews with key informants such as Tianqin musicians and craftsmen. Data analysis was performed using thematic analysis, revealing that (...) the Tianqin has transitioned from a ritualistic instrument to a symbol of cultural heritage and mass entertainment. The findings highlight the instrument's adaptability through innovations in playing techniques and materials, supported by governmental initiatives promoting Tianqin culture. This research underscores the importance of preserving and promoting traditional musical instruments in contemporary society. The study's insights contribute to a broader understanding of cultural adaptation and innovation in ethnomusicology. (shrink)

Codes of medical ethics (codes) are part of a longstanding tradition in which physicians publicly state their core values and commitments to patients, peers, and the public. However, codes are not static. Using the historical evolution of the Canadian Medical Association's Code of Ethics as an illustrative case, we argue that codes are living, socio-historically situated documents that comprise a mix of prescriptive and aspirational content. Reflecting their socio-historical situation, we can expect the upheaval of the COVID-19 pandemic to prompt (...) calls to revise codes. Indeed, Alex John London has argued in favour of specific modifications to the World Medical Association's International Code of Medical Ethics (which has since been revised) in light of moral and scientific failures that occurred during the COVID-19 pandemic. Responding to London, we address the more general question: should codes be modified to reflect lessons drawn from the COVID-19 pandemic or future such upheavals? We caution that codes face limitations as instruments of policy change because they are inherently interpretive and ‘multivocal’, that is, they usually underdetermine or provide more than one answer to the question, ‘What should I do now?’ Nonetheless, as both prescriptive and aspirational documents, codes also serve as tools for reflection and deliberation—collective practices that are necessary to engaging with and addressing the moral and scientific uncertainties inherent to medicine.

Abstract During the last decades it has become widely accepted that scientific observations are ?theory?laden?. Scientists ?see? the world with their theories or theoretical presuppositions. In the present paper it is argued that they ?see? with their scientific instruments as well, as the uses of scientific instruments is an important characteristic of modern natural science. It is further argued that Euclidean geometry is intimately linked to technology, and hence that it plays a fundamental part in the construction and (...) operation of scientific instruments. Finally, Euclidean geometry is compared to fractal geometry, and the question of its a priori status is raised. Although the position that Euclidean geometry is a priori in the original Kantian sense is untenable, the paper concludes that in some restricted sense Euclidean geometry may be said to be a priori.

The Kunstkammer of the Electors of Saxony, founded in Dresden around 1560, housed one of the richest collections of tools and scientific instruments in its day. A close analysis of the optical objects in the collection in the decades around 1600 is undertaken here—in particular, their arrangement by a mathematically trained curator, Lucas Brunn, and their use in an ‘experiment’ by a distinguished visitor, Johannes Kepler. It is argued that the selection, display and use of optical objects within this (...) collection reflect a specific, playful image of optics promoted at the Saxon court.Keywords: Court collections; Optics; Instruments; Perspective; Wonder.

What should and what should not to be counted as a human right? What does it mean to identify a right as a human right? And what are the most effective and legitimate means of promoting human rights? This book addresses these questions and the complex relationship between the answers to them.

East India Company surveyors began gaining access to the high Himalaya in the 1810s, at a time when the mountains were taking on increasing political significance as the northern borderlands of British India. Though never as idiosyncratic as surveyors insisted, these were spaces in which instruments, fieldbook inscriptions, and bodies were all highly prone to failure. The ways surveyors managed these failures (both rhetorically and in practice) demonstrate the social performances required to establish credible knowledge in a world in (...) which the senses were scrambled. The resulting tensions reveal an ongoing disconnect in understanding between those displaced not only from London, but also from Calcutta, something insufficiently emphasized in previous histories of colonial science. By focusing on the early nineteenth century, often overlooked in favor of the later period, this article shows the extent to which the scientific, imaginative, and political constitution of the Himalaya was haphazard and contested.

This article discusses an approach to translational bioethics (TB) that is concerned with the adaptation—or ‘translation’—of concepts, theories and methods from bioethics to practical contexts, in order to support ‘non-bioethicists’, such as researchers and healthcare practitioners, in dealing with their ethical issues themselves. Specifically, it goes into the participatory development of clinical ethics support (CES) instruments that respond to the needs and wishes of healthcare practitioners and that are tailored to the specific care contexts in which they are to (...) be used. The theoretical underpinnings of this participatory approach to TB are found in hermeneutic ethics and pragmatism. As an example, the development of CURA, a low-threshold CES instrument for healthcare professionals in palliative care, is discussed. From this example, it becomes clear that TB is a two-way street. Practice may be improved by means of CES that is effectively tailored to specific end users and care contexts. The other way around, ethical theory may be enriched by means of the insights gained from engaging with practice in developing CES in a process of co-creation. TB is also a two-way street in the sense that it requires collaboration and commitment of both bioethicists and practitioners, who engage in a process of mutual learning. However, substantial challenges remain. For instance, is there a limit to the extent to which a method of moral reasoning can be adapted in order to meet the constraints of a given healthcare setting? Who is to decide, the bioethicist or the practitioners? (shrink)

This study explores the philosophical and religious dimensions of Lusheng musical instruments in the Qiandongnan Miao and Dong Autonomous Prefecture, Guizhou Province, China. The study's qualitative research method involved conducting interviews and observations, and the use of qualitative research design grounded in ethnomusicological theory and philosophical and religious frameworks. A purposive sampling technique was used to identify participants comprising musicians, community leaders, artisans, religious figures, and elders having extensive knowledge about Lusheng traditions. A thematic content analysis approach was used (...) to analyze the data collected. The results of the study reveals that the Miao and Dong communities deeply integrate one Lusheng instrument, a traditional reed-pipe, into their cultural, spiritual, and social fabric. The research highlights Lusheng’s significance in religious ceremonies such as funerals and the Drum Zang Festival, where it functions as a sacred medium, facilitating communication with ancestors and deities. Philosophically, Lusheng music embodies communal unity, continuity and the interconnectedness of life and death. Economically, Lusheng music supports local artisans and performers, contributing to the region’s economy through its production and performance during festivals and tourist attractions. Educationally, Lusheng music fosters cultural identity, religious understanding, and artistic expression, ensuring its transmission across generations. Through formal and informal educational programs, the Lusheng remains a vibrant part of community life, blending tradition with creative innovation. The study underscores the importance of preserving Lusheng as both a cultural and spiritual artifact, enriching the lives of the Miao and Dong people while maintaining its relevance in the modern world.

Designing and developing a digital musical instrument (DMI) to a level of refinement that provides musically rich applications and nuanced interaction capabilities requires a long-term commitment to both technical and creative aspects. This process often leads to the acquisition of sensory, communicative, and intuitive knowledge—dimensions of instrument design that are typically overlooked in mainstream discussions. This paper explores this development journey through the lens of three instruments: the Resonant Object Interface (ROI), the Floors, and the Table Floor. These (...) class='Hi'>instruments have undergone extensive development, with the latest instrument building upon the lessons learned from the previous two. We discuss the challenges encountered during the ongoing refinement of these devices and our evolving interaction with their physical complexities. A key focus is the tacit knowledge gained through hands-on engagement, which, though often taken for granted once established, requires significant time and effort to develop. Further, we reflect on our experiences sharing these instruments with other musicians, highlighting how tacit engagement plays a critical role in the creation of new processes, materials, sensing technologies, and sensory experiences in the realm of digital musical instrument design.

Background There has been significant discussion about the need to manage conflict of interest (COI) in medical journals. This has lead many journals to implement policies to manage COI for authors and reviewers; however, surprisingly little attention has been focused on the COI of journal editors. Objective The goal of this exploratory study was to determine whether the policies were accessible to the public and to researchers, and to discuss the potential impact on public transparency. Design The authors conducted an (...) internet search of editor COI policy instruments that have been developed, implemented and communicated by the top 10 peer-reviewed medical journals (2010 ISI Web of Knowledge Impact Factor), and assessed their general accessibility by gauging the level of difficulty in navigating the journal's website (number of clicks to find the policy instruments). Results Only four of the 10 medical journals (40%) in this study have accessible COI policy directives that include editors (JIM, PLoS Medicine, AIM, CMAJ). One journal (NEJM) had an editorial on the subject, and another (The Lancet) mentioned editor COI in their general guidelines. These documents are not readily accessible; starting from the journal's main website at least four clicks are needed to access these documents. Conclusion These results suggest that there is a general lack of accessible editor COI policy instruments among leading medical journals, something that may consequently have a negative impact on the trust accorded to these journals.

This book provides a philosophical framework to understand computer simulations as scientific instruments. This is in sharp contrast to existing philosophical approaches on the subject, which have historically understood computer simulations as either formal abstractions or as broadly construed empirical practices. In order to make its case, the volume contains a thorough examination of conventional philosophical approaches as well as their respective limitations. Yet, also, unlike other accounts of computer simulations from the perspective of the philosophy of science, this (...) book incorporates insights from the philosophy of technology and the history of science. Hence, the book offers philosophers of science, technologists and other researchers interested in the topic, a thorough overview of the philosophical issues regarding the design, development and deployment of computer simulations in science and science-based policy making.

Developmental, epidemiological, and neurobiological studies indicate that the adaptive and maladaptive functions, as well as immediate and long-term consequences of drug use, may vary by age. Early initiation seems to be associated with a reduced ability to use drugs purposely in a temporally stable, non-addictive manner. Prevention strategies should consider social environmental factors and aim to delay age at initiation.

The variety of evidence thesis in confirmation theory states that more varied supporting evidence confirms a hypothesis to a greater degree than less varied evidence. Under a very plausible interpretation of this thesis, positive test results from multiple independent instruments confirm a hypothesis to a greater degree than positive test results from a single instrument. We invoke Bayesian Networks to model confirmation on grounds of evidence that is obtained from less than fully reliable instruments and show that the (...) variety of evidence thesis is not sacrosanct when testing is conducted with less than fully reliable instruments: under certain conditions, a hypothesis receives more confirmation from evidence that is obtained from one rather than from more independent instruments. In the appendix, we prove certain convergence results for large numbers of positive test results from single versus multiple less than fully reliable instruments. (shrink)

This book examines the intricate web linking water science and society using diverse philosophical lenses. Highlighting the tensions within the threads of this web, we spotlight major conceptual tightropes that water researchers tread daily. To effectively navigate these delicate threads, a 'healthy' tension in the encompassing web is necessary. Drawing inspiration from Freud's examination of tensions in "Society and Its Discontents," we illuminate the tension-filled paradoxes inherent to water science, emphasizing the challenges in keeping these paradoxical threads taut enough to (...) ensure a navigable and sustainable bond with society. Central to our narrative is the escalating societal urge to quantify and 'manage' water—something interwoven throughout every environmental layer, including the fabric of our being. An excessive focus on management may alienate users from their water realities, jeopardizing the vital threads that sustainability tether water science and society. Consequently, this book explores compelling and inescapable tensions that resist tidy universal resolution, such as: the language of water science, including its mathematical reductions (i.e., models); the effect of water's commodification on its science; hydrology’s intersection with colonialism; and other concerns that reveal distortions in our hydrology. We aim to aid water professionals in recognizing and fine-tuning the paradoxes intrinsic to their work. To underscore the interwoven complexity of contemporary hydrology, "Hydrology and Its Discontents" guides readers into the tempestuous depths of water research, all the while urging a recalibration of perspectives and motivations.

Rudolph Koenig's workshop was a busy meeting place for instruments, ideas, experiments, demonstrations, craft traditions, and business. Starting around 1860, it was also the place in Paris where people discovered the new science of sound emerging from the studies of Hermann von Helmholtz in Germany. Koenig built Helmholtz's ideas into apparatus, created new instruments, and spread them throughout the scientific and musical world. Through his own research, he also became Helmholtz's strongest critic. This paper looks at the activities (...) of this unique space and, in particular, how it contributed to the protracted disputes over an elusive acoustical phenomenon called the combination tone.

The European Union is making increased efforts to find simpler and more effective ways to function adequately in the eyes of its citizens by using ‘soft law’ instruments such as recommendations. Although they have no legally binding force, recommendations have practical and legal effects occurring partly due to their normative content in which a course of action is prescribed and further supported by arguments intended to persuade the addressees of a political position. Although recommendations function as persuasive instruments (...) due to their argumentation, the characteristics of argumentation and how it is employed to convince the addressee to comply with certain measures have not been investigated at all. The main goal of the paper is to explain how arguments are used by the European Commission when recommending Member States to follow a new course of action. First, we will unravel the justificatory reasons employed by the Commission in order to make Member States comply with new measures and we will show how these reasons are combined into an argumentative pattern : 1–23, 2016; J Argum Context 6: 3–26, 2017). This pattern basically prescribes a course of action to Member States, which is further supported by arguments in which the necessity and advantages of following the proposed course of action are justified. Second, we will explain how and why the way in which the arguments are combined in this complex pattern could be potentially persuasive for the Member States despite the legally non-binding character of recommendations. We will show that the European Commission tries to persuade the Member States to take new measures by evading the burden of proof imposed by the legislative framework. At a more specific level of analysis, we will delve into the implicit premises in the argumentation, which enable us to identify cases of evasion of the burden of proof due to the Commission’s use of implicit starting points which might not be accepted by the Member States.

Faraday demonstrated electromagnetic induction in 1831 using an iron ring wound with two wire coils; on interrupting battery current in one coil, momentary currents arose in the other. Between Faraday's ring and the induction coil, coiled instruments developed via meandering paths. This paper explores the opening phase of that work in the late 1830s, as the iron core, primary wire coil, and secondary wire coil were researched and differentiated. ‘Working knowledge’ gained with materials and phenomena was crucial to innovations. (...) To understand these material-based interactions, I experimented with hand-wound coils, along with examining historical texts, drawings, and artefacts. My experience recovered the historical dead-end of two-wire coils and ensuing work with long-coiled single conductors initiated by Faraday and Henry. The shock and spark heightened in these coils provided feedback to the many instrumental configurations tested by Page, Callan, Sturgeon, Bachhoffner, and others. The continuous conductor differentiated into two segments soldered together: a thick short wire carrying battery current and a long thin wire for elevating shocks . The joined wires eventually separated, yet their transitional connection documents belief that the induced effects depend on continuity. These coiled instruments, with their intertwined histories, show experimental work and understandings in the process of developing. Seeing the nonlinear paths by which these instruments developed deepens our understanding of historical experiences, and of how people learn. (shrink)
