The Philosophical Association of the Visayas and Mindanao (PHAVISMINDA), founded in 1979, is one of the oldest philosophical organizations in the country that continued to exist until the present time. This interview article focused on this organization as something distinct from the other major national philosophical organizations of the country, such as the Philosophical Association of the Philippines, the Philosophy Circle of the Philippines, and the Philippine National Philosophical Research Society. Using the method of oral history, this paper tried to (...) document and assess: 1) how PHAVISMINDA differentiated itself from the other major Philippine national philosophical organizations; 2) PHAVISMINDA’s general stand on the development of Filipino philosophy, the contextualization of philosophy to the realities of the Visayas and Mindanao, and the use of Cebuano language in philosophizing; 3) the trends of the research projects of its leading writers/thinkers; 4) its exemplary presidents and their lasting imprints on the organization; and 5) the general direction where the organization is heading. The respondents of this interview article are: 1) Dr. Amosa Velez, of the University of San Carlos, founding member of the organization, practically the first president, and three-time president; 2) Dr. Jane Gallamaso, of Xavier University, and the tenth president of the organization; and 3) Dr. Ruby Suazo, of the University of San Carlos, and the twelfth and current president of the organization.

Shannon’s information theory has been a popular component of first-order cybernetics. It quantifies information transmitted in terms of the number of times a sent symbol is received as itself, or as another possible symbol. Sent symbols were events and received symbols were outcomes. Garner and Hake reinterpreted Shannon, describing events and outcomes as categories of a stimulus attribute, so as to quantify the information transmitted in the psychologist’s category (or absolute judgment) experiment. There, categories are represented by specific stimuli, (...) and the human subject must assign those stimuli, singly and in random order, to the categories that they represent. Hundreds of computations ensued of information transmitted and its alleged asymptote, the sensory channel capacity. The present paper critically re-examines those estimates. It also reviews estimates of memory capacity from memory experiments. It concludes that absolute judgment is memory-limited and that channel capacities are actually memory capacities. In particular, there are factors that affect absolute judgment that are not explainable within Shannon’s theory, factors such as feedback, practice, motivation, and stimulus range, as well as the anchor effect, sequential dependences, the rise in information transmitted with the increase in number of stimulus dimensions, and the phenomena of masking and stimulus duration dependence. It is recommended that absolute judgments be abandoned, because there are already many direct estimates of memory capacity. (shrink)

I argue for the conditions that eco-sabotage (sabotage involving the protection of animals or the environment) must meet to be a morally permissible form of activism in a liberal democracy. I illustrate my case with Jessica Reznicek and Ruby Montoya’s oil pipeline destruction, the Sea Shepherd Conservation Society’s whale hunt sabotage, and the Valve Turners’ pipeline shut-off, climate necessity-defense. My primary contention is that just as it is permissible to destroy an attacker’s weapon in self- or other-defense, it is (...) permissible to engage in some forms of eco-sabotage. Taking inspiration from just war theory, I use the conditions of just cause, reasonable chance of success, proportionality, necessity, and discrimination to both conceptualize eco-sabotage as defense and illustrate the justificatory burden the eco-saboteur must meet. Often eco-sabotage is doubly pro-tanto wrong because it is illegal and involves property destruction. Overcoming these hurdles is particularly difficult because in seemingly bypassing democratic means of dispute resolution, the eco-saboteur seemingly coerces the other members of society by forcing idiosyncratic views upon them. Non-anthropocentric eco-sabotage grounded in defense of animal rights has mixed results regarding the democratic objection just described. I argue that anthropocentric eco-sabotage, grounded in defense of human rights, has the best chance of overcoming this objection, provided a persuasive case can be made for its reasonable chance of success. Passing a reasonable chance of success also causes problems for non-anthropocentric eco-sabotage grounded in species defense, while non-anthropocentric eco-sabotage grounded in defense against animal suffering has a lighter justificatory burden.

Purpose – The purpose of this paper is to examine the popular “information transmitted” interpretation of absolute judgments, and to provide an alternative interpretation if one is needed. Design/methodology/approach – The psychologists Garner and Hake and their successors used Shannon’s Information Theory to quantify information transmitted in absolute judgments of sensory stimuli. Here, information theory is briefly reviewed, followed by a description of the absolute judgment experiment, and its information theory analysis. Empirical channel capacities are scrutinized. A remarkable coincidence, (...) the similarity of maximum information transmitted to human memory capacity, is described. Over 60 representative psychology papers on “information transmitted” are inspected for evidence of memory involvement in absolute judgment. Finally, memory is conceptually integrated into absolute judgment through a novel qualitative model that correctly predicts how judgments change with increase in the number of judged stimuli. Findings – Garner and Hake gave conflicting accounts of how absolute judgments represent information transmission. Further, “channel capacity” is an illusion caused by sampling bias and wishful thinking; information transmitted actually peaks and then declines, the peak coinciding with memory capacity. Absolute judgments themselves have numerous idiosyncracies that are incompatible with a Shannon general communication system but which clearly imply memory dependence. Research limitations/implications – Memory capacity limits the correctness of absolute judgments. Memory capacity is already well measured by other means, making redundant the informational analysis of absolute judgments. Originality/value – This paper presents a long-overdue comprehensive critical review of the established interpretation of absolute judgments in terms of “information transmitted”. An inevitable conclusion is reached: that published measurements of information transmitted actually measure memory capacity. A new, qualitative model is offered for the role of memory in absolute judgments. The model is well supported by recently revealed empirical properties of absolute judgments. (shrink)

Purpose – A key cybernetics concept, information transmitted in a system, was quantified by Shannon. It quickly gained prominence, inspiring a version by Harvard psychologists Garner and Hake for “absolute identification” experiments. There, human subjects “categorize” sensory stimuli, affording “information transmitted” in perception. The Garner-Hake formulation has been in continuous use for 62 years, exerting enormous influence. But some experienced theorists and reviewers have criticized it as uninformative. They could not explain why, and were ignored. Here, the “why” (...) is answered. The paper aims to discuss these issues. Design/methodology/approach – A key Shannon data-organizing tool is the confusion matrix. Its columns and rows are, respectively, labeled by “symbol sent” (event) and “symbol received” (outcome), such that matrix entries represent how often outcomes actually corresponded to events. Garner and Hake made their own version of the matrix, which deserves scrutiny, and is minutely examined here. Findings – The Garner-Hake confusion-matrix columns represent “stimulus categories”, ranges of some physical stimulus attribute (usually intensity), and its rows represent “response categories” of the subject’s identification of the attribute. The matrix entries thus show how often an identification empirically corresponds to an intensity, such that “outcomes” and “events” differ in kind (unlike Shannon’s). Obtaining a true “information transmitted” therefore requires stimulus categorizations to be converted to hypothetical evoking stimuli, achievable (in principle) by relating categorization to sensation to intensity. But those relations are actually unknown, perhaps unknowable. Originality/value – The author achieves an important understanding: why “absolute identification” experiments do not illuminate sensory processes. (shrink)

Web applications are increasing day by day and the choice of technology for building a web application is a tedious task. A good website needs to be scalable, functional, responsive, reliable, secure etc. Therefore, comparing the different trending technologies for web design is crucial. The entire design of our website requires the selection of the programming languages. It is difficult to give a quick solution to this issue without first considering what our website will do both now and in the (...) future. One of the initial decisions to be made is whether the website will be static, interacting with users relatively little, or dynamic, displaying personalised information to users in response to interactions. Also, there are many stacks trending and available in the market for web development like MERN stack, MEAN stack, MEVN stack or ruby on rails or DERN technology. It's very necessary to understand all, the key differences between them and which one is right to choose when. This paper attempts to assist web developers through conducting an empirical comparison of the most significant web-based programming languages and databases. The paper compares frontend technologies like React and Angular based on certain parameters like DOM, architecture and data binding, in each case comparing their performance and also do the performance analysis of backend technologies like MongoDB and PostgreSQL, which are no-SQL and SQL databases respectively, based on e-commerce use case application. The paper finally suggests which technology to choose for which use case and under what conditions and requirements. (shrink)

This paper reveals errors within Norwich et al.’s Entropy Theory of Perception, errors that have broad implications for our understanding of perception. What Norwich and coauthors dubbed their “informational theory of neural coding” is based on cybernetics, that is, control and communication in man and machine. The Entropy Theory uses information theory to interpret human performance in absolute judgments. There, the continuum of the intensity of a sensory stimulus is cut into categories and the subject is shown exemplar stimuli of (...) each category. The subject must then identify individual exemplars by category. The identifications are recorded in the Garner-Hake version of the Shannon “confusion matrix”. The matrix yields “H”, the entropy (degree of uncertainty) about what stimulus was presented. Hypothetically, uncertainty drops as a stimulus lengthens, i.e. a plot of H vs. stimulus duration should fall monotonically. Such “adaptation” is known for both sensation and firing rate. Hence, because “the physiological adaptation curve has the same general shape as the psychophysical adaptation curve”, Norwich et al. assumed that both have the same time course; sensation and firing rate were thus both declared proportional to H. However, a closer look reveals insurmountable contradictions. First, the peripheral neuron hypothetically cannot fire in response to a stimulus of a given intensity until after somehow computing H from its responses to stimuli of various intensities. Thus no sensation occurs until firing rate adapts, i.e. attains its spontaneous rate. But hypothetically, once adaptation is complete, certainty is reached and perception ends. Altogether, then, perception cannot occur until perception is over. Secondly, sensations, firing rates, and H’s are empirically not synchronous, contrary to assumption. In sum, the core concept of the cybernetics-based Entropy Theory of Perception, that is, that uncertainty reduction is the basis for perception, is irrational. (shrink)
