The paper attempts to provide a basis for exploring the continued relevance of Catholic social teaching to business ethics, byinterpreting the historic development of a Catholic work ethic and the traditions of Catholic social teaching in light of contemporary discussions of economic globalization, notably those of Robert Reich and Peter Drucker. The paper argues that the Catholic work ethic and the Church’s tradition of social teaching has evolved dynamically in response to the structural changes involved in the history of modern (...) economic development, and thus is well poised to speak to the ethical challenges implicit in the advent of a knowledge-based society. In order to test this thesis, the author sketches an approach to the ethical challenge of corporate downsizing that he believes illustrates the continued relevance of Catholic social teaching to business ethics.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

To mitigate the spread of schistosomiasis, a deterministic human-bovine mathematical model of its transmission dynamics accounting for contaminated water reservoirs, including treatment of bovines and humans and mollusciciding is formulated and theoretically analyzed. The disease-free equilibrium is locally and globally asymptotically stable whenever the basic reproduction number R0<1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$R_0<1$$\end{document}, while global stability of the endemic equilibrium is investigated by constructing a suitable Lyapunov function. To support the analytical results, parameter values from published (...) literature are used for numerical simulations and where applicable, uncertainty analysis on the non-dimensional system parameters is performed using the Latin Hypercube Sampling and Partial Rank Correlation Coefficient techniques. Sensitivity analysis to determine the relative importance of model parameters to disease transmission shows that the environment-related parameters namely, εs\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\varepsilon _s$$\end{document} (snails shedding rate of cercariae), ps\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$p_s$$\end{document} (probability that cercariae shed by snails survive), c (fraction of the contaminated environment sprayed by molluscicides) and μc\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\mu _c$$\end{document} (mortality rate of cercariae) are the most significant to mitigate the spread of schistosomiasis. Mollusciciding, which directly impacts the contaminated environment as a single control strategy is more effective compared to treatment. However, concurrently applying mollusciciding and treatment will yield a better outcome. (shrink)

Ethical decision-making is essential to professionalism in engineering. For that reason, ethics is a required topic in an ABET approved engineering curriculum and it must be a foundational strand that runs throughout the entire curriculum. In this paper the curriculum approach that is under development at the Padnos School of Engineering (PSE) at Grand Valley State University will be described. The design of this program draws heavily from the successful approach used at the service academies — in particular West Point (...) and the United States Naval Academy. As is the case for the service academies, all students are introduced to the “Honor Concept” (which includes an Honor Code) as freshmen. As an element of professionalism the PSE program requires 1500 hours of co-op experience which is normally divided into three semesters of full-time work alternated with academic semesters during the last two years of the program. This offers the faculty an opportunity to teach ethics as a natural aspect of professionalism through the academic requirements for co-op. In addition to required elements throughout the program, the students are offered opportunities to participate in service projects which highlight responsible citizenship. These elements and other parts of the approach will be described. “Train up a child in the way he should go and when he is old he will not depart from it.” King Solomon. (shrink)

The value of argumentation in science education has become internationally recognised and has been the subject of many research studies in recent years. Successful introduction of argumentation activities in learning contexts involves extending teaching goals beyond the understanding of facts and concepts, to include an emphasis on cognitive and metacognitive processes, epistemic criteria and reasoning. The authors focus on the difficulties inherent in shifting a tradition of teaching from one dominated by authoritative exposition to one that is more dialogic, involving (...) small-group discussion based on tasks that stimulate argumentation. The paper focuses on how argumentation activities have been designed in school science. Examples of classroom dialogue where teachers adopt the frameworks/plans are analysed to show how argumentation processes are scaffolded. The analysis shows that several layers of interpretation are needed and these layers need to be aligned for successful implementation. (shrink)

Crudely put, educational research is unethical when it misrepresents or misidentifies—and so betrays—its putative beneficiaries or the goods and values they hold dear. How can researchers guard against these vulnerabilities? While acknowledging the vulnerabilities of educational research to abuses of trust and representation, and that there is no Archimedean point from which to approach research into people’s practices, we defend a universalist conception of research ethics in education. This universalist conception is developed via an examination of a central debate in (...) feminism, contrasting Alcoff’s positionality, Caughie’s performative conception and Nussbaum’s universalist conception of feminism.

This volume covers the philosophical, historical, religious, and interpretative aspects of the ancient Guodian bamboo manuscripts which were disentombed in the Guodian Village in Hubei Province, China, in 1993. Considered to be the Chinese equivalent of the Dead Sea Scrolls, these manuscripts are archaeological finds whose importance cannot be underestimated. Many of the texts are without counterparts in the transmitted tradition, and they provide unique insights into the developments of Chinese philosophy in the period between the death of Confucius and (...) the writings of Mencius, and beyond. Divided into two parts, the book first provides inter-textual contexts and backgrounds of the Guodian manuscripts. The second part covers the main concepts and arguments in the Guodian texts, including cosmology and metaphysics, political philosophy, moral psychology, and theory of human nature. The thematic essays serve as an introduction to the philosophical significance and the key philosophical concepts/thought of each text contained in the Guodian corpus. Each chapter has a section on the implications of the texts for the received tradition, or for the purpose of comparing some of the text with the received tradition in terms of the key philosophical concepts as well as the reading and interpretation of the texts. The volume covers most of the texts inscribed on the 800-odd slips of the Guodian corpus dated to the fourth century BCE. (shrink)

The stereotyped pattern of cell commitments during leech embryogenesis is described. The nature of cell commitments during segmentation differs significantly between leech and fruit fly. Despite the constancy of cell fate assignments in normal development, ablation experiments show that cell interactions are essential in setting some of these commitments. Interacting cells follow a positionally determined hierarchy of fate choices. For other cells, which appear to have fates fixed from birth, the possibility of determinative interactions between mother and daughter cells is (...) discussed. (shrink)

During embryogenesis, cell division must be spatially and temporally regulated with respect to other developmental processes. Leech embryos undergo a series of unequal and asynchronous cleavages to produce individually recognizable cells whose lineages, developmental fates and cell cycle properties have been characterized. Thus, leech embryos provide an opportunity to examine the regulation of cell division at the level of individual well‐characterized cells within a community of different types of cells. Isolation of leech homologues of some of the highly conserved regulators (...) of the cell division cycle, and characterization of their patterns of maternal and zygotic expression, indicate that the cell divisions of early leech embryos are regulated by cell type‐specific mechanisms. These studies with leech embryos contribute to the emerging appreciation of the diverse mechanisms by which animals regulate cell division during early development. (shrink)

Zhong 中 is an important notion in early Chinese thought. This essay offers a brief survey of the possible connotations of zhong found in the Baoxun 保訓 text of the Tsinghua University’s Collection of bamboo manuscripts of the Warring States period. By making a preliminary textual analysis and philosophical interpretation of the concept of zhong in relation to ideal rulership as presented in this newly discovered ancient text it is hoped that it will shed some light on the continuing debate (...) on the notion of zhong in early Chinese thought.

Falls are a leading cause of serious injury and restricted participation among persons with stroke (PwS). Reactive balance control is essential for fall prevention, however, only a few studies have explored the effects of lesion characteristics (location and extent) on balance control in PwS. We aimed to assess the impact of lesion characteristics on reactive and anticipatory balance capacity, gait, and hemiparetic lower limb function, in PwS. Forty-six subacute PwS were exposed to forward, backward, right and left unannounced horizontal surface (...) translations in 6 increasing intensities, while standing. Fall threshold (i.e., perturbation intensity that results in a fall into the harness system) was measured. In addition, the Berg Balance Scale (BBS), 6 Minute Walk Test (6MWT) and Lower Extremity Fugl-Meyer (LEFM) were measured. Lesion effects were analyzed separately for left- and right-hemisphere damaged (LHD, RHD) patients, using voxel-based lesion-symptom mapping (VLSM). Our results show that voxel clusters where damage exerted a significant impact on balance, gait and lower-limb function were found in the corticospinal tract, in its passage in the corona radiata and in the posterior limb of the internal capsule. Additional significant impact was found to lesions affecting the putamen and the external capsule. Balance, gait, and hemiparetic lower limb function showed much overlap of the corresponding ‘significant’ voxel clusters. Test scores of RHD and LHD patients were affected largely by damage to homologous regions, with the LHD group showing a wider distribution of ‘significant’ voxels. The study corroborates and extends previous findings by demonstrating that balance control, gait, and lower limb function are all affected mainly by damage to essentially the same brain structures, namely - the corticospinal tract and adjacent structures in the capsular-putaminal region.

This study examines how low-income African American mothers of children with sickle cell disease cope with the reproductive implications of having passed a genetic disease on to their children. Based on in-depth interviews with 29 African American mothers, I found that most mothers knew about SCD prior to having a child with the disease; many knew they were carriers of the sickle cell trait. In explaining why this knowledge did not lead them to alter their reproductive behaviors, mothers invoked a (...) theme of medical mismanagement; that is, they said the genetic screening programs for SCD did not provide them with enough medical knowledge about the disease. The implication that adequate knowledge about SCD would have affected their childbearing choices, however, is contradicted by their subsequent reproductive behaviors. I argue that the SCD diagnosis threatened motherhood, an important cultural value among low-income African American women, and that they protected their reproductive autonomy by obfuscating SCD medical knowledge.

In a modern economy, “equilibrium” means that supply and demand is equal. It is at this point that the allocation of goods and services is at its most efficient, this being because the amount of goods and the amount of goods in demand are equally balanced. The market equilibrium therefore is determined by supply and demand. This paper looks at the concept of “equilibrium” in some of the early Confucian texts and its possible implications in economic activities. In the Confucian (...) context equilibrium, or what can be termed as the ultimate equilibrium, is to be understood in a broader sense where balances and harmony at different levels (e.g. individual and society) need to be sought in order to achieve a model of sustainable development. The ultimate equilibrium may provide an alternative approach to social welfare and economic prosperity creating universal harmony and better living for humans. In Confucian ideology, governing for the welfare of the people is not merely a question of increasing personal income and wealth; it requires implementation on a priority basis, taking into consideration the formation of an orderly society based on the enforcement of moral and ethical standards with the existence of a benevolent government which appropriates things according to the principles of harmony and order to achieve what can be termed as the “great equilibrium”—equilibrium that is not simply defined by balanced economic forces as in modern economic theory; but rather is used to suggest an ideal state of harmony in self fulfilment and socio-political order through incentives and by appropriate means.

In this sequel of my previous publication, I will continue my discussion of the word tian as it appears in the Guodian texts. I shall argue that, from natural order arises xing, human's distinctive potentiality, which is endowed by heaven to follow and be guided by the heavenly principle. I thereafter will elaborate the sages' role as cultural creators. The distinct roles of heaven and humanity are further deepened when tian and ming are perceived as the determinants of an individual's (...) success or failure. I will go on to show how the word tian can be understood as the source or underlying pattern that brings about coincidental or synchronous events and experiences. (shrink)
