The Market for Firms: Market Signaling and Overpricing  [PDF]
Jerome Davis, Hans Keiding
Technology and Investment (TI) , 2010, DOI: 10.4236/ti.2010.13024
Abstract: In this paper, the pricing and sale of firms is approached from the owners’ point of view. It is shown that there are very strong ex ante owner incentives to set prices of firm products or services below their short- term profit maximizing levels, since low prices signal low costs and as a consequence a higher sales value of the firm. Buyers take this signaling into consideration, but irrespective of their countermoves, the equilib- rium result may be a lowering of ex ante product prices, and an ex post market overvaluation of the firm. This model is utilized to suggest possible explanations to one of the more puzzling initial public offer (IPO) phenomena: the long run underperformance of IPO equities.
Addendum to: An Approach to Hierarchical Clustering via Level Surfaces and Convexity  [PDF]
Jerome Malitz, Seth Malitz
Intelligent Information Management (IIM) , 2010, DOI: 10.4236/iim.2010.25035
Abstract: This article is an addendum to the 2001 paper [1] which investigated an approach to hierarchical clustering based on the level sets of a density function induced on data points in a d-dimensional feature space. We refer to this as the “level-sets approach” to hierarchical clustering. The density functions considered in [1] were those formed as the sum of identical radial basis functions centered at the data points, each radial basis function assumed to be continuous, monotone decreasing, convex on every ray, and rising to positive infinity at its center point. Such a framework can be investigated with respect to both the Euclidean (L2) and Manhattan (L1) metrics. The addendum here puts forth some observations and questions about the level-sets approach that go beyond those in [1]. In particular, we detail and ask the following questions. How does the level-sets approach compare with other related approaches? How is the resulting hierarchical clustering affected by the choice of radial basis function? What are the structural properties of a function formed as the sum of radial basis functions? Can the levels-sets approach be theoretically validated? Is there an efficient algorithm to implement the level-sets approach?
Prayer for Good Governance: A Study of Psalm 72 in the Nigeria Context  [PDF]
Mary Jerome Obiorah
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.31A032

Contextualizationof Biblical texts is a priority of every exegete, who endeavors to bring the ancient scripts to dialogue with contemporary issues. This paper, which studies Psalm 72 and a prayer composed for good governance in Anambra State Nigeria, focuses on this hermeneutical interpretation. The writer adopts a simplified literary method in Biblical research that takes cognizance of the varied poetic techniques in Psalm 72 and engages in a detailed comparative study of a Psalm composed more than two millennia ago and a prayer of our time. Such comparative study reveals a striking similar preoccupation of the composers of both texts. Both prayed for good governance of which all developing countries today are in dire need.

The Role of Philosophy in Modern Medicine  [PDF]
Mbih Jerome Tosam
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.41011

In this paper I argue that contrary to what some philosophers think, there exists a very close link between philosophy and medicine. From ancient Greece with Hippocrates to the modern era, philosophy has been at the basis of medicine. This is especially true of Western medicine which greatly depends on the philosophies of Bacon and Descartes. Although the two disciplines seem to pursue two disparate goals— philosophy being the quest for truth while medicine is the quest for health, they are in complementary ways striving for the enhancement of human wellbeing. While medicine seeks to fight diseases of the body like bacteria and viruses, philosophy seeks to fight the diseases of the mind like half-truths, prejudices, woolly judgments and uncritical conceptions of the world, health and disease, which have direct impact on health, and health delivery. Using substantive examples, I show that the practice of medicine raises questions beyond the scope of medicine, questions to which only philosophy may provide answers because they fall within its scope. Daily, physicians are confronted with questions in such philosophical areas like metaphysics, epistemology, ethics, and logic. Moreover, I argue that one of the weaknesses of modern Western medicine is its over-dependence on the Cartesian ontology which considers human bodies as machines which need to be studied using scientific logic, and the physician as a technician whose job is to repair dysfunctioned bodies. This modern metaphysical outlook resulted in the neglect of the patient as a subjective being. This deficiency cannot be overcome without reviewing the Cartesian reductionist worldview which is at its foundation.

“Do Not Weep” (Luke 7: 13): In the Footstep of the Compassionate Jesus  [PDF]
Mary Jerome Obiorah
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.43028

The divine image, which every human being bears as a result of God’s benevolence at creation, attracts us to the Divine. Human beings are religious by nature and in order to fully realise themselves as humans they have to be and live out the divine qualities instilled in each of them by the Creator. The opposite is often the case when human actions are critically evaluated. One of the divine qualities, which we ought to acquire and practice in order to enhance good human relationship, is compassion. This singular divine feature characterised Jesus earthly ministry in words and deeds. In this paper, the writer focuses on an episode in the life of Jesus, as recorded in the Gospel according to Luke 7: 11-17. Jesus had compassion on the widow who lost her only son; he consoled and restored her son back to her. In following Jesus’ footsteps we can make our world better and be able to bear and live with others.

Balancing Scales of Language Injustice  [PDF]
Jerome Rabow, Manpreet Dhillon
Sociology Mind (SM) , 2015, DOI: 10.4236/sm.2015.51003
Abstract: This paper addresses the ways in which our everyday usage of the common phrase “people of color” perpetuates a basic inequality in language use. A suggestion to eliminate inequality in teaching is proposed.
“Like Olive Shoots”: Insight into the Secret of a Happy Family in Psalm 128  [PDF]
Mary Jerome Obiorah
Open Journal of Philosophy (OJPP) , 2015, DOI: 10.4236/ojpp.2015.51008
Abstract: Beset by all kinds of ideologies that divest it of its divinely endowed values, family in our contemporary society suffers greatly from those who purport to have a better way of fulfilling its divine mandate. All who understand the importance of family are greatly concerned at the overt derailment that has proved detrimental to human society. The Sacred Scripture offers us varied insights into solving the problem in which we find ourselves. Psalm 128 chosen for this paper is one of those texts in the Bible that reflects on family and its value in human society. As a Wisdom Psalm and didactic in nature, the poem presents to its readers what family is in dire need of at this time. The meaning of this Psalm is coded in its rich poetic techniques and similes that the paper endeavours to explain in its immediate context as a Song of Ascents and in the contexts of other Wisdom texts of the Old Testament. Its theological thrust, the fear of God, which is introduced at the beginning and iterated in various phrases within the Psalm comes out clearly as messages the Psalm offers to worrisomely deformed image of family in our time.
African Environmental Ethics and Sustainable Development  [PDF]
Mbih Jerome Tosam
Open Journal of Philosophy (OJPP) , 2019, DOI: 10.4236/ojpp.2019.92012
Abstract: In this paper, I argue that African environmental ethics can contribute to sustainable development as well as mitigate the devastating effects of global warming and climate change in Africa. Although Africa bears the least onus of responsibility for global warming and climate change, she suffers the greatest burden of the adverse effects of global climate change and environmental crisis. While industrialized countries, nations which are largely responsible for the greatest amount of greenhouse emissions are laggard and reticent in implementing international agreements aimed at palliating the untoward effects of climate change, there is an urgent need to seek indigenous solutions to environmental crisis in Africa without compromising the much needed development in the continent. African environmental ethics extends the moral community beyond anthropocentric concerns by including non-human animals, plants, the unborn, and the supernatural into the moral universe. I use Kom environmental ethics to show how indigenous African societies employed different values and customs to make their environment physically and spiritually sustainable. There were taboos, values, and norms which prescribed correct behavior towards nature. But as a result of the colonial encounter, Africans were forced to abandon some of these indigenous environmental values and sustainable practices for an anthropocentric approach. With this outlook where humans have moral responsibility only towards humans, development meant the complete disregard for traditional African holistic values and customs. This disregard, in conjunction with weak or absence of institutional framework regarding environmental protection and corruption in the management of natural resources, has led to unsustainable exploitation of the natural environment in Africa.

Biota Neotropica , 2008, DOI: 10.1590/S1676-06032008000200001
Abstract: the main objective of this paper is to present and discuss the best methods to estimate live above ground biomass in the atlantic forest. the methods presented and conclusions are the products of a workshop entitled "estimation of biomass and carbon stocks: the case of atlantic rain forest". aboveground biomass (agb) in tropical forests is mainly contained in trees. tree biomass is a function of wood volume, obtained from the diameter and height, architecture and wood density (dry weight per unit volume of fresh wood). it can be quantified by the direct (destructive) or indirect method where the biomass quantification is estimated using mathematical models. the allometric model can be site specific when elaborated to a particular ecosystem or general that can be used in different sites. for the atlantic forest, despite the importance of it, there are only two direct measurements of tree biomass, resulting in allometric models specific for this ecosystem. to select one or other of the available models in the literature to estimate agb it is necessary take into account what is the main question to be answered and the ease with which it is possible to measure the independent variables in the model. models that present more accurate estimates should be preferred. however, more simple models (those with one independent variable, usually dbh) can be used when the focus is monitoring the variation in carbon storage through the time. our observations in the atlantic forest suggest that pan-tropical relations proposed by chave et al. (2005) can be confidently used to estimated tree biomass across biomes as long as tree diameter (dbh), height, and wood density are accounted for in the model. in atlantic forest, we recommend the quantification of biomass of lianas, bamboo, palms, tree ferns and epiphytes, which are an important component in this ecosystem. this paper is an outcome of the workshop entitled "estimation of biomass and carbon stocks: the case of atlantic rain fore
