Whilst the role of Maturation or M‐phase Promoting Factor (MPF) as a universal M‐phase regulator is well documented, much less attention has been paid to its role in nuclear transplantation experiments and especially to its influence upon remodelling of transplanted nuclei. There is currently wide acceptance that successful nuclear transplantation using differentiated nuclei is possible only in a cytoplasmic environment that is capable of inducing rapid nuclear de‐differentiation to a pronuclear‐like form. In this review our purpose is firstly, to outline (...) the conditions under which such remodelling can be induced, and secondly, to extend the debate to include a consideration of whether complete nuclear remodelling is an absolute necessity for clonal development.

Contemporary psychological research that studies how people apply mathematics has largely viewed mathematics as a computational tool for deriving an answer. The tacit assumption has been that people first understand a situation, and then choose which computations to apply. We examine an alternative assumption that mathematics can also serve as a tool that helps one to construct an understanding of a situation in the first place. Three studies were conducted with 6th‐grade children in the context of proportional situations because early (...) proportional reasoning is a premier example of where mathematics may provide new understanding of the world. The children predicted whether two differently‐sized glasses of orange juice would taste the same when they were filled from a single carton of juice made from concentrate and water. To examine the relative contributions and interactions of situational and mathematical knowledge, we manipulated the formal features of the problem display (e.g., diagram vs. photograph) and the numerical complexity (e.g., divisibility) of the containers and the ingredient ratios. When the problem was presented as a diagram with complex numbers, or “realistically” with easy numbers, the children predicted the glasses would taste different because one glass had more juice than the other. But, when the problem was presented realistically with complex numbers, the children predicted the glasses would taste the same on the basis of empirical knowledge (e.g., “Juice can't change by itself”). And finally, when the problem was presented as a diagram with easy numbers, the children predicted the glasses would taste the same on the basis of proportional relations. These complex interactions illuminate how mathematical and empirical knowledge can jointly constrain the construction of a new understanding of the world. We propose that mathematics helped in the case of successful proportional reasoning because it made a complex empirical situation cognitively tractable, and thereby helped the children construct mental models of that situation. We sketch one aspect of the mental models that are constructed in the domain of quantity—a preference for specificity—that helps explain the current findings. (shrink)

Clinical ethics consultants face a wide range of ethical dilemmas that require broad knowledge and skills. Although there is considerable overlap with the approach to adult consultation, ethics consultants must be aware of differences when they work with infant, pediatric, and adolescent cases. This article addresses unique considerations in the pediatric setting, reviews foundational theories on parental authority, suggests practical approaches to pediatric consultation, and outlines current available resources for clinical ethics consultants who wish to deepen their skills in this (...) area.

A major American writer at the turn of this millennium, Leslie Marmon Silko has also been one of the most powerful voices in the flowering of Native American literature since the publication of her 1977 novel Ceremony. This guide, with chapters written by leading scholars of Native American literature, explores Silko's major novels Ceremony, Almanac of the Dead, and Gardens in the Dunes as an entryway into the full body of her work that includes poetry, essays, short fiction, film, photography, (...) and other visual art. These chapters map Silko's place in the broad context of American literary history. Further, they trace her pivotal role in prompting other Indigenous writers to enter the conversations she helped to launch. Along the way, the book engages her historical themes of land, ethnicity, race, gender, trauma, and healing, while examining her narrative craft and her mythic lyricism. (shrink)

The Gauss-Hertz principle is extended by the use of existence conditions (or constraints) to obtain a hierarchy of differential equations which include all classical equations of continuum mechanics (including electrodynamics) and the harmonic oscillator potential as well.

This important book makes a bold statement about the nature and value of anthropological theory at the beginning of the 21st century.

Ethics and Educational Technology explores the creation and implementation of learning technologies through an applied ethical lens. The success of digital tools and platforms in today's multifaceted learning and performance contexts is dependent not only on effective design and pedagogical principles but, further, on an awareness of these technologies' interactions with and implications for users and social systems. This first-of-its-kind book provides an evidence-based, process-oriented model for ethics in technology-driven instructional design and development, one that necessitates intentional reflective practice, a (...) critical and theoretically informed interrogation of technology, and a participatory, emancipatory approach to technology design and applications. Rich with real-world ethics examples and design cases, supported by reflection questions and applied activities, and attentive to ethical codes among preeminent educational technology organizations, this is an ideal resource for students, faculty, researchers, and professionals across educational technology, instructional design, learning sciences, learning engineering, organizational training, and other disciplines.

This book focuses on six key practices for engaged learning: acknowledging and building on students' prior knowledge and experiences; facilitating relationships; offering feedback; framing connections to broader contexts; fostering reflection and metacognition; and promoting integration and transfer of knowledge and skills.

This dissertation serves as a monograph on the moral and social implications of a utilitarian-based system of health care which recognizes and takes rights seriously. Though the design and claims are stated primarily in terms of utilitarianism, admittedly, there are elements of communitarian, deontological, and rights theories which have been incorporated. ;Such a commingling of theoretical elements, under the claim of being utilitarian, may seem ambiguous, however, it is my contention that such inclusions only serve to enhance the plausible nature (...) of this sphere-specific form of utilitarianism and the adjudication of rights. Additionally, though there are other components of theories included, the basis of utilitarianism still serves as the foundation by which all other actions, decisions, and values are judged. ;While it is true that utilitarianism offers a standard for all areas of life, the idea of examining a sphere or environment of utility, in this case, the utility associated with the sphere of health care, allows for the good to be clearly defined. One primary weakness of classical utilitarianism is that it ignores, or at least does not do full justice to, the notion of personal responsibility or sense of obligation. If the only duty or requirement is to produce some obscure sense of the "greatest good" or the "greatest happiness," the question of how the good is identified and who is to have the good remains unanswered by the traditional utilitarian construct. ;The classical view of utilitarianism is too broad in its scope of defining "the greatest good" or realm of value. But to narrow the area of value to a particular sphere or environment allows for the utility and associated rights in question to be identified, the value measured, and the success more easily interpreted. ;While maintaining the general premise of utilitarianism, that is, "the greatest good for the greatest number," the notion is not from some nebulous concept or subjective position about life or feelings in general. This sphere-specific position also acknowledges and defines the "rights" of the individual within the particular sphere being considered, in this case, the sphere of health care. (shrink)

Little research has explored the perceptions of military medical providers in the deployed environment and how their perceptions may change over time across an extended military conflict. To our knowledge, no studies have examined military medical providers’ opinions on readiness for their roles in the post-9/11 contingency operations. What has been published indicates that, during the height of Operation Iraqi Freedom, military medical providers often deployed with little notice and minimal formal training. The present report examines data obtained from multiple (...) cohorts of military medical providers (N = 321) deployed to Iraq between 2005 and 2009. Despite varying degrees of support from the U.S. public, our findings indicate that U.S. Air Force military medical providers’ support for the people of Iraq, their belief in the mission, and their ability to influence change did not vary with time.

In this introduction to the Synthese SI: The Cultural Evolution of Human Social Cognition, we introduce some basic theoretical terms that will help readers to navigate the volume. Subsequently we describe the papers that make up the volume and draw attention to points of agreement and disagreement between the authors. We also identify a number of outstanding issues for the field of cultural evolution research. The papers in the volume can be divided into three sections: The Cultural Evolution of Mindreading, (...) The Cultural Evolution of Ethics and Aesthetics, and Methodological Challenges. (shrink)

The continuum form of the Gauss-Hertz principle is extended to include the time domain as well as space. The Schrödinger equation and general relativity are derived by this method. The equivalence of the principle is shown to that of the Hamiltonian method where the energy is the expression −[φ∇ 2 φ+A·∇2 A], with φ being the difference between the acceleration potential and potential energy density, andA being the difference between the vector potentials of the acceleration field and the force field. (...) The goal of Hertz to “demonstrate a third arrangement of the principles of mechanics...which starts with... time, space and mass” has apparently been achieved for relativity and for quantum mechanics, in addition to those classical equations previously found.

We argue that the self-experimentation espoused by Roberts as a means of generating new ideas, particularly in the area of mood, may be confounded by the experimental procedure eliciting those affective changes. We further suggest that ideas might be better generated through contact with a broad range of people, rather than in isolation.

This article asks if and under what conditions ethnic diversity could become the foundation for a prosperous society. Recent studies on ethnic diversity and social cohesion suggest that diversity has a negative effect on social cohesion and therefore is detrimental to the social prosperity of individuals and communities. This article argues that although such a negative correlation may apply to contexts with well-consolidated ethnic groups, it does not necessarily apply to ‘super-diverse’ places with multiple small ethnic groups and multiple social, (...) legal and cultural differences that cut across ethnicity. Drawing on ethnographic material from East London, the authors contend that, in super-diverse places, ethnic diversity could become a valuable aspect of community life, while inequalities in social, cultural and symbolic capital become central points of social antagonism to the detriment of prosperity.

ObjectiveApproximately half of all people living with amyotrophic lateral sclerosis experience persistent or recurrent emotional distress, yet little is known about the psychological processes that maintain emotional distress in this population. The self-regulatory executive functioning model specifies that maladaptive metacognitive beliefs and processes are central to the development and maintenance of emotional distress. This study explored whether maladaptive metacognitive beliefs are associated with emotional distress after controlling for demographic factors, time since diagnosis, and current level of physical functioning.DesignIn a cross-sectional (...) design, 75 adults with a diagnosis of ALS completed self-report questionnaires. Participants had a mean age of 60.40 years, mean duration of symptoms 63.92 months, and male:female gender ratio of 14:11.Main Outcome MeasuresQuestionnaires assessed emotional distress, physical functioning, repetitive negative thinking, metacognitive beliefs, and demographic factors.ResultsMaladaptive metacognitive beliefs explained additional variance in emotional distress after controlling for age, gender, time since diagnosis, physical functioning, and repetitive negative thinking. Repetitive negative thinking partially mediated the relationships between positive and negative metacognitive beliefs and emotional distress.ConclusionsThese data support the utility of the metacognitive model in understanding emotional distress in people with ALS. Examination of the temporal relationship between maladaptive metacognitive beliefs and emotional distress in people living with ALS may help to guide the development of therapeutic approaches.

Journalism educators who appear as expert witnesses and consultants in media law cases such as libel and invasion of privacy are often unfamiliar with the practical aspects of serving as an eflective, efficient, and ethical expert. These practical dimensions include federal and state rules of evidence and civil procedure, the process of deciding whether or not to accept a case, negotiations over fees and employment conditions, ethical conflicts associated with representation, the litigation process, and post-trial issues. It is unusual, especially (...) in media law cases, for an expert's testimony to make or break a case, but a client has a right to expect aggressive and rigorous representation and ready accessibilityfrom the expert. The challenge facing the journalism educator who serves as an expert witness is balancing those demands with the responsibilities of being a professor while avoiding conflicts of interest. (shrink)

Previous research has shown that the activation of a goal leads to more implicit positivity toward goal-relevant stimuli. We examined how the actual pursuit of a goal influences subsequent implicit positivity toward such stimuli. Participants were consciously or non-consciously primed with a goal, or not, and then completed a goal-relevant task on which they succeeded or failed. We then measured their goal-relevant implicit attitudes. Those who were primed with the goal (consciously or non-consciously) and experienced success exhibited more implicit positivity (...) toward the goal, compared with the no-goal condition. Experiencing failure in the goal priming conditions reduced implicit positivity toward the goal, indicating disengagement from the goal. We discuss the theoretical implications for understanding the role of implicit attitudes in self-regulation. (shrink)

Diversity in society can be viewed from two perspectives, normative and descriptive, both of which define how we think, discuss, and live. Normatively we are called to be responsible. This notion ideally depicts the vision of people of various backgrounds and beliefs living with an attitude of tolerance, respect, and the desire for justice. Descriptively, it is to recognize that people of diverse ethnic, social, economic, and philosophical backgrounds come together to live in various geographic locations, often resulting in heated (...) tension and turmoil. Cultural backgrounds are a primary source of identity for many and serve as a foundation for a great deal of self-definition, expression, and sense of individual identity and group belonging.

Instead of attempting to reduce rituals of healing to so‐called primitive psychotherapy this essay raises the question of whether contemporary psychotherapies might not fruitfully be viewed as ritual processes through which a small segment of modern society receives ritual leadership in times of crisis. Selected phenomena in contemporary psychotherapeutic practice are analyzed in an attempt to discern the ritual processes which are manifest in them. It is concluded that most modalities of contemporary psychotherapy manifest elements of ritualized submission, containment, and (...) enactment. (shrink)
