A Poisson-Akash Inrar(1) Model For Over Dispersed Count Time Series, Emmanuel W. Okereke, Sunday N. Gideon

BAU Journal - Science and Technology

In this paper, a Poisson-Akash INAR(1) model was proposed in order to improve on the modelling of overdispersed stationary count time series. The estimators of the parameters of the model were derived using the Yule-Walker (YW) method and the conditional least squares (CLS) method. An expression for the conditional log-likelihood and the r-step ahead forecast were obtained for the model. Three overdispersed nonseasonal stationary count time series were modelled to illustrate the applicability of the proposed model as well as its capacity to outperform the competing INAR (1) models in modelling overdispersed stationary count time series and the result showed …

Walking Diagonally: A Simple Proof Of Countability Of The Set Of All Finite Subsets Of Naturals, Miroslav Kures

BAU Journal - Science and Technology

The countability of the set of finite subsets of natural numbers is derived. In addition to the derivation itself, the use of diagonal method is illustratively presented; thinking about infinite sets relate to the name of Georg Ferdinand Ludwig Philipp Cantor, the creator of set theory, which has become a fundamental theory in mathematics. The proof of the claim is original, although the theorem is an analogy with the famous theorem about the countability of rational numbers. A certain insight into the subsets of natural numbers is given. Anyway, the technique could be considered already at high school level as …

HCA Healthcare Journal of Medicine

Programmed cell death receptor 1 (PD-1) inhibitors are promising and effective treatments for various cancers. Cutaneous adverse events, such as lichenoid drug eruptions, are well-known common side effects associated with PD-1 inhibitors. Lichenoid drug eruptions associated with PD-1 inhibitors show rapid improvement with high potency topical steroids and do not require cessation of the offending drug. We present the case of an 84-year-old female with progressive pembrolizumab therapy-associated lichenoid eruption that was resistant to several treatments and ultimately required discontinuation of pembrolizumab and treatment with methotrexate to resolve. This report includes histological findings of the pembrolizumab-associated lichenoid eruption.

Cosmopolitanism, Creolization, And Non-Exceptionalist Buddhist Modernisms: On Evan Thompson’S Why I Am Not A Buddhist, Yarran Hominh, A. Minh Nguyen

Comparative Philosophy

In his recent book, Why I Am Not a Buddhist, Evan Thompson argues that inter-tradition or cross-cultural philosophical dialogue ought to be governed by cosmopolitan conversational norms that do not subsume any one tradition’s deep commitments under those of any other tradition, but rather bring those commitments into the discussion so that they can be challenged and defended. He argues on this basis for the application of a deeply contextualist and historicist interpretive methodology to Buddhist texts, concepts, and theories in dialogue with philosophy and contemporary cognitive sciences. Buddhist modernism, in eschewing that deeply contextualist and historicist methodology, falls …

A Sonogram Of The Dark Side Of The Dao: The Possibility Of Antinatalism In Daoism, Robbert Zandbergen

Comparative Philosophy

In the present work I study Daoist philosophy in conjunction with the radical new philosophy of antinatalism, spearheaded by South African philosopher David Benatar. Although I am not claiming equivalence between the two, a meaningful communication emerges between the classical Chinese sources used here and the modern doctrine of antinatalism. I argue that both visions partake in a radical critique of consciousness according to which this faculty of the human mind is far from what it is often held to be. In fact, it is perceived as a destructive and disruptive element of, and in, existence. Moreover, both offer a …

Sameness, Difference And Environmental Concern In The Metaphysics And Ethics Of Spinoza And Chan Buddhism, Michael Hemmingsen

Comparative Philosophy

In this paper I contrast the metaphysical philosophies of Benedict de Spinoza and the ‘sudden enlightenment’ tradition of Chan Buddhism. Spinoza’s expressivist philosophy, in which everything can be conceived via a lineage of finite causes terminating in substance as a metaphysical ground of all things, emphasises the relative sameness of all entities. By contrast, Chan’s philosophy of emptiness, which rests on the dependent co-origination of all entities, renders such comparison fundamentally meaningless. Having no source beyond dependent co-origination to generate a thing’s distinct nature leads to a metaphysics in which, rather than being relatively similar or different, all things …

The Yi-Jing Cosmic Model As A Framework For Comparative Philosophy, Harry Donkers

Comparative Philosophy

Based on the symbolism of the trigrams, the Yi-Jing cosmic model offers possibilities in a coordinate system with eight octants to discuss different philosophical developments in parallel. It forms a framework for further elaboration of theory and methodology of comparative philosophy. This paper is restricted to extracting, analyzing and comparing common features from the perspectives of the Yi-Jing model. Achieving harmony is the subject of a new paper under construction. The philosophical developments in the quadrants, Naturalism, Moralism, Rationalism and Humanism, are characterized by a fundamental difference between subject and object. This difference remains intact in the octants, but specified …

Appearance And Momentariness: The Nature Of Being Between Nāgārjuna, The Sarvāstivādins And Neo-Parmenidism, Federico Divino

Comparative Philosophy

In this article I will try to demonstrate the existence of points in common between the eternalist instances of Parmenidean philosophy and the Buddhist formulations made by some parts of the Abhidhamma, Nāgārjuna, and the Sarvāstivādins. These three philosophies have numerous points in common with Emanuele Severino’s formulations from the point of view of what is defined as neo-Parmenidism. The purpose of this article is to demonstrate that the points in common between these systems of thought are due to a basic affinity which, despite having led them to emphasize different themes, present similar reasoning and logical consequences, which allow …

IGC Proceedings (1977-2023)

Atmospheric CO₂ concentrations have been increasing since the industrial revolution, and are projected to double within this century over today's concentration of 360 µmol mol^-1 . This study used six open-top chambers in the Colorado, USA shortgrass steppe to investigate how increasing CO₂ will affect productivity and C and N status of indigenous perennial grasses and forbs. From March until October, chambers were placed on two plots in each of the three blocks. In each block, one chamber was assigned an ambient CO₂ treatment (~360 µmol mol^-1), the other an elevated CO₂ treatment …

Rangeland Desertification In China, Wang Tao

IGC Proceedings (1977-2023)

Land desertification is one of the most serious environmental and social-economic problems in the North China. The processes of desertification mainly have being controlled by the interaction of human activities and fragile eco-environment, that means the pattern and intension of landuse are major factors for development or reverse of desertification. Because of the increasing pressure of population, the rangeland in the North China has being cultivated decade by decade, which changed landuse from grassing to cropping in a large area and destroyed the natural vegetation cover. The result is to let the wind erosion become easier and the desertification has …

Grasslands, Communicating The Benefits, D. Keeney

IGC Proceedings (1977-2023)

The multiple benefits of perennial agriculture , including forages and grasslands, for building soil quality, protection of natural resources, enhancement of biodiversity and wildlife, are well known to us, but little understood by the public. This is not a situation where “more education” would necessarily increase recognition. Rather, we must build in the public a desire for the enhancement of green space, clean water and air, and diverse landscapes that multiple purpose agriculture can bring. We seek such environments intuitively and now that much of the world’s people are “trapped” in urban settings of steel and concrete, this desire is …
