Due to natural selection pressure, certain aspects of memory may have been selected to give humans a survival advantage. Research has demonstrated that processing information for survival relevance leads to better item memory (i.e., the content of information) compared to control conditions. The current study investigates the effects of survival processing on context memory (i.e., memory for peripheral episodic details) and item memory to better understand when the survival processing memory advantage emerges. In this study, participants (...) viewed objects in either a plausible color, for example a red apple, or in an implausible color, such as a green pie. We chose this color plausibility manipulation because color is a detail that conveys information about the fitness of an item. After studying items in either a survival or moving (control) condition, participants made item memory judgments (did you see this item before?), and two context memory judgments: color context (in which color did you see this item?), and source context (in which condition did you see this item?). Results indicated better item memory for materials processed in the survival relative to moving condition. Critically, for color context there was a condition by plausibility interaction, where memory was best for plausibly colored items in the survival processing condition. There was no difference, however, in source context memory between the survival and moving conditions. These results suggest the survival processing memory advantage extends to some contextual details, but only those details that tap into the survival utility of items, such as color. (shrink)

Processing information in the context of personal survival scenarios elicits a memory advantage, relative to other rich encoding conditions such as self-referencing. However, previous research is unable to distinguish between the influence of survival and self-reference because personal survival is a self-referent encoding context. To resolve this issue, participants in the current study processed items in the context of their own survival and a familiar other person’s survival, as well as in a semantic context. (...) Recognition memory for the items revealed that personal survival elicited a memory advantage relative to semantic encoding, whereas other-survival did not. These findings reinforce suggestions that the survival effect is closely tied with self-referential encoding, ensuring that fitness information of potential importance to self is successfully retained in memory.

This paper investigates the impact of kin on child survival in a matrilineal society in Malawi. Women usually live in close proximity to their matrilineal kin in this agricultural community, allowing opportunities for helping behavior between matrilineal relatives. However, there is little evidence that matrilineal kin are beneficial to children. On the contrary, child mortality rates appear to be higher in the presence of maternal grandmothers and maternal aunts. These effects are modified by the sex of child and resource (...) ownership: female children and children in households where women, rather than men, own land suffer higher mortality rates in the presence of maternal kin. These modifiers suggest the detrimental effects of matrilineal kin may result from competition between such kin for resources. There are some positive effects of kin on child survival: the presence of elder siblings of both sexes is correlated with higher survival rates, and there is some weak evidence that paternal grandmothers may be beneficial to a child’s survival chances. There is little evidence that any male kin, whether matrilineal or patrilineal, and including fathers, affect child mortality rates. This study highlights the importance of taking social and ecological context into account when investigating relationships between kin. (shrink)

Suppose various observers are divided randomly into two groups, a large and a small. Not knowing into which group anyone has been sent, each can have strong grounds for believing in being in the large group, although recognizing that every observer in the other group has equally powerful reasons for thinking of this other group as the large one. Justified belief can therefore be observer-relative in a rather paradoxical way. Appreciating this allows one to reject an intriguing new objection (...) against Brandon Carter's 'doomsday argument'. Carter encourages us to doubt that we are among only the first hundredth, say, or first millionth, of all humans who will ever have existed. He thereby reinforces whatever reasons we may have for suspecting that, unless we take great care, the human race will not survive long. Admittedly his argument is weakened if our world is indeterministic, so that there is no suitably guaranteed 'fact of the matter' of how many humans will ever have existed. But even then, it can caution us against believing that a lengthy future for humankind 'is as good as determined'. Of all the objections the argument has yet faced, the new one is the most interesting. (shrink)

Rationale Treatment guidelines recommend a more conservative surgical approach than mastectomy for early stage breast cancer and a stronger emphasis on adjuvant therapy. Registry data at South Australian teaching hospitals have been used to monitor survivals and treatment in relation to these guidelines.Aims and objectives To use registry data to: (1) investigate trends in survival and treatment; and (2) compare treatment with guidelines.Methods Registry data from three teaching hospitals were used to analyse trends in primary courses of treatment of (...) breast cancers during 1977–2003 (n = 4671), using univariate analyses and multiple logistic regression. Disease-specific survivals were analysed using Kaplan–Meier product limit estimates and multivariable Cox proportional hazards regression.Results The 5-year survival was 79.9%, but with a secular increase, reaching 83.6% in 1997–2003. The relative risk of death (95% confidence limits) was 0.74 (0.62, 0.88) for 1997–2003, compared with previous diagnoses, after adjusting for tumour node metastasis stage, grade, age and place of residence. Treatment changes included an increase in conservative surgery (as opposed to mastectomy) from 51.7% in 1977–1990 to 76.8% in 1997–2003 for stage I (P < 0.001) and from 31.1% to 52.2% across these periods for stage II (P < 0.001). Adjuvant radiotherapy also became more common (P < 0.001), with 20.6% of patients receiving this treatment in 1977–1990 compared with 60.7% in 1997–2003. Radiotherapy generally was more prevalent when conservative surgery was provided, although also relatively common in mastectomy patients when tumour diameters exceeded 50 mm or when there were four or more involved nodes. The proportion of patients receiving chemotherapy increased (P < 0.001), from 19.6% in 1977–1990 to 36.9% in 1997–2003, and the proportion having hormone therapy also increased (P < 0.001), from 34.3% to 59.4% between these periods.Conclusions Survivals appear to be increasing and treatment trends are broadly consistent with guideline directions, and the earlier research on which these recommendations were based.

Death has a social meaning in every culture. It is not something that concerns only the person who dies, but also his or her family, friends and other people in the community. Most people have an idea of what counts as a good death—for the person concerned or for those who survive. Some people would prefer to die suddenly and painlessly, in their sleep if possible. But for many people, a good death is a process in which they gradually lose (...) their hold on life, become reconciled to their end and say goodbye to their loved ones. From the point of view of relatives and friends, a good death is likely to be one in which they have a chance to show their feelings for the dying person and to become reconciled to their loss as the patient’s life fades away. At the end of this process, there is a dead body that can be put to rest in an appropriate ceremony, and then those still surviving are free to begin learning to live without the dead person.Problems, ethical and social, arise when the social understanding of death and how the living should relate to the dead and dying clash with medical definitions of death, ….

In contrast with views that attribute the biological utility of beliefs to their truth, Nietzsche maintains that their relative utility renders them proportionately more likely to be idiosyncratic expressions of species‐relative concerns. Nietzsche's sceptical ‘argument from utility’—the inference from the practical utility of beliefs to the improbability of their being metaphysically true—is examined and rejected. It is argued that Nietzsche is an early proponent of naturalized epistemology. His objections to the ‘best explanation’ defence of metaphysical realism are discussed. (...) It emerges that the ‘evolutionary’ strand of thought is incompatible with his other sceptical arguments. The chapter pursues Nietzsche's doctrine that the ‘ruling drives’ representing the dominant manifestation of the will to power in an individual determine the standards for validation, evidence, and truth. The discussion proceeds to an examination of Nietzsche's remarks that the external world is created in a manner depending on the specific form of the will to power instantiated by the empirical subject.

The act of killing self contradicts the central purpose of human evolution, that is, survival and propagation of one’s genetic material. Yet, it continues to be one of the leading causes of human death. A handful of theories in the realm of evolutionary psychology have attempted to explain human suicide. The current article analyses the major components of certain prominent viewpoints, namely, Inclusive fitness, Bargaining model, Pain-Brain model, Psychological aposematism, and few other perspectives. The article argues that relatively more (...) weightage has been given to understanding ultimate (the “why”) rather than proximate (the “how”) functionality of suicidal acts. Evolutionary theorists have consistently pointed out that to comprehensively understand a trait or behavior, one needs to delineate not only how it supports survival but also the evolution of the mechanisms underlying the trait or behavior. Existing theories on suicide have primarily focused on its fitness benefits on surviving kin instead of providing evolutionary explanations of the more complex mechanisms leading up to such self-destructive motivations. Thus, the current paper attempts to highlight this gap in theorizing while suggesting probable proximate explanations of suicide which stresses the need to diffuse attention paid to fitness consequences of the act alone. We speculate that such explorations are needed in order to build a robust and comprehensive evolutionary theory of human suicide. (shrink)

Consensus in the contemporary philosophical literature has it that conserved quantity theories of causation such as that of Dowe [2000]—according to which causation is to be analysed in terms of the exchange of conserved quantities (e.g., energy)—face damning problems when confronted with contemporary physics, where the notion of conservation becomes delicate. In particular, in general relativity it is often claimed that there simply are no conservation laws for (say) total-stress energy. If this claim is correct, it is difficult to see (...) how conserved quantity theories of causation could survive. In this article, we resist the above consensus and defend conserved quantity theories from this conclusion, at least when focusing on the apparent problems posed by general relativity. We argue that this approach to causation can continue to be defended in general relativity, once one appreciates (a) the availability of approximate symmetries in generic general relativistic spacetimes, and (b) the role of modelling and idealisation in that theory. Given these points, conserved quantity theories of causation must stand or fall on other grounds. (shrink)

Abstractc‐Rel is a proto‐oncogene first identified as the cellular counterpart of the v‐Rel oncogene derived from the avian reticuloendotheliosis retrovirus (REV‐T). It was subsequently discovered that c‐Rel belongs to the NF‐κB/Rel transcription factor family whose members share a common DNA recognition motif and similar signaling pathways. Despite the similarities, however, each NF‐κB/Rel member possesses unique properties with regard to tissue expression pattern, response to receptor signals and target gene specificity. These differences are fairly evident from the non‐redundant phenotypes exhibited by (...) individual NF‐κB/Rel knockout mice. Hence the work described in this review will compare and contrast the various physiological functions of c‐Rel to those of other NF‐κB members, particularly with respect to the regulation of proliferation, survival and effector functions in multiple hematopoietic and immunological cell types. The study of c‐Rel knockout mice in several disease models will also be discussed as they reveal an important role for c‐Rel in response to allergens, auto‐antigens, allo‐antigens and pathogenic infection.

Don Marquis has argued most abortions are immoral, for the same reason that killing you or me is immoral: abortion deprives the fetus of a valuable future. Call this account the FLOA. A rival account is Jeff McMahan’s, time-relative interest account of the wrongness of killing. According to this account, an act of killing is wrong to the extent that it deprives the victim of future value and the relation of psychological unity would have held between the victim at (...) the time of death and herself at a later time if she had lived. The TRIA supposedly has two chief advantages over Marquis’s FLOA. First, unlike the FLOA, the TRIA does not rely on the controversial thesis that identity is what matters in survival. Second, the TRIA yields more plausible verdicts about cases. Proponents of the TRIA use the account to argue that abortion is generally permissible, because there would be little to no psychological unity between the fetus and later selves if it lived. I argue that advocates of the TRIA have failed to establish its superiority to the FLOA, for two reasons. First, the two views are on a par with respect to the thesis that identity is what matters in survival. Second, Marquis’s FLOA does not yield the counterintuitive implications about cases that advocates of the TRIA have attributed to it, and the TRIA yields its own share of implausible judgments about cases.

Southern Appalachia is unique among agroecological regions of the American South because of the diverse environmental conditions caused by its mountain ecology, the geographic and commercial isolation of the region, and the relative cultural autonomy of the people that live there. Those three criteria, combined with a rich agricultural history and the continuance of the homegardening tradition, make southern Appalachia an area of relatively high crop biodiversity in America. This study investigated the history and survival of traditional heirloom (...) vegetable crops in western North Carolina and documented 134 heirloom varieties that were still being grown. I conducted interviews with 26 individuals from 12 counties in western North Carolina. I used a snowball sampling method to identify individuals or communities that maintained heirloom vegetable varieties, and used the “memory banking” of farmers’ knowledge as a strategy to complement the gathering of seed specimens. Most of the varieties were grown and saved by homegardeners; beans were the most numerous. Results indicate that usually only one or two individuals in a community maintained significant numbers of heirloom varieties and that many communities have lost their heirloom vegetable heritage altogether. The decline of the farming population combined with a lack of cultural continuance in family seed-saving traditions threatens the ability of communities to maintain crop biodiversity. Some of the cultivars may represent the last (small) populations of endangered varieties. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Structure, Change, and Survival: A Response To Winthrop-youngFranco Moretti (bio)Geoffrey Winthrop-Young’s is the sort of review article one dreams of: long, intelligent, and very generous. So, first of all, thanks. And thanks also for the clarity with which disagreements are expressed. In the same spirit, here is a brief response.The first area of disagreement comes early in the article, when Winthrop-Young claims that in the Atlas, “the here (...) and now of a specific location suffers something akin to the fate of a Barthesian myth: its specificity is subordinated to a signifying function as part of an established narrative sequence. But as Moretti chooses not to address the question of how this transformation is achieved, his discussion tends to gloss over the differences between geographical, literary, and imaginary locations” [7]. Frankly, I don’t think this is true. I often do exactly what Winthrop-Young demands, using a sequence of maps to clarify the successive steps by which a geographical space ends up supporting a specific narrative strucure: see the Austen maps that open the book, or the picaresque sequence in the first chapter, or the Balzac and Dickens maps in the second chapter—where I also address the issue in conceptual terms in a section entitled “Stories of the Third.” It’s true that I don’t do so in every case (as perhaps I should), and Winthrop-Young may of course disagree with the way I chart the transformation of space into narrative, but he cannot deny that I am doing so. The fact that those maps compose sequences of increasing complexity (as is particularly clear for Austen and Our Mutual Friend) proves precisely that I am indeed mapping a “transformation” of relatively simple beginnings into a complicated final structure. Incidentally, I do something similar in Modern Epic, where I describe how Joyce’s stream of consciousness “grows” from rather slim paragraphs to the plump ones we read now, or follow the slow rise of Ulysses’s polyphony. Again: my theses may be wrong—but they are an attempt to follow the step-by-step structuration of a text (or genre). This, after all, is the basic test of critical materialism: if we cannot describe the how and the why of the various steps, we are implicitly invoking “creativity” as an explanation for literary products. Which is a bit like invoking God. But on the futility of this, Winthrop-Young and I probably agree.The second disagreement regards the tempo of literary history: does morphological change occur in brief bursts separated by long periods of stasis (as in Eldredge and Gould’s punctuated equilibria)—or is it more evenly distributed across time? Here, Winthrop-Young claims [36, fn 5] that my attempt to see Schwarz’s account of Brazilian modernism and the genesis of magic realism as a single instance of punctuated equilibria is contradicted by historical evidence. He is right. Years ago, I adopted punctuated equilibria because it proved better than any rival theory at explaining the peculiar rapidity of many literary turning points (baroque drama; the rise of the British novel; the modernist season of European literature). From this initial conviction, I was (unconsciously) led to generalize, and to treat every case of major morphological change as an instance of punctuated equilibria. This was silly, and Winthrop-Young is right in criticizing me. However, he would probably agree that a single (or even a few) contrary [End Page 41] instances do not invalidate a theory in its entirety, and that what we most need is to know more about how literary change occurs. Only after such an empirical reconnaissance will the testing of theories be on a truly sound basis. Personally, I wouldn’t be surprised if we discovered that literary change can occur in more than one way, and that we need more than one theory to account for it; still, all I know of literary history suggests that punctuated equilibria will be the theory with greatest explanatory power.The last disagreement concerns literary selection: specifically, whether my view of it is indeed Darwinian, or whether I Lamarck-like “transform the concept of selection from the traditional passive filter...

Taking the formal analogies between black holes and classical thermodynamics seriously seems to first require that classical thermodynamics applies in relativistic regimes. Yet, by scrutinizing how classical temperature is extended into special relativity, I argue that the concept falls apart. I examine four consilient procedures for establishing the classical temperature: the Carnot process, the thermometer, kinetic theory, and black-body radiation. I argue that their relativistic counterparts demonstrate no such consilience in defining the relativistic temperature. As such, classical temperature doesn’t appear (...) to survive a relativistic extension. I suggest two interpretations for this situation: eliminativism akin to simultaneity, or pluralism akin to rotation. (shrink)

Three members of the Jewish tribe Qurayẓa, two brothers and their relative, left the tribe’s besieged fortress hours before Qurayẓa’s unconditional surrender to the Prophet Muḥammad, thereby saving their lives, their families, and their orchards. According to a rather widespread account, the three had become convinced of the veracity of Muḥammad’s mission. But there is a more cogent explanation for their survival: according to Ibn al-Kalbī’s Kitāb al-Mathālib, the two brothers were married to two sisters who were Muḥammad’s (...) third cousins.

This paper outlines a phenomenological approach for describing physiological reactions occurring immediately after vital threats. This exemplified by data taken from previous studies relative to chemical intoxications of rats by a neurotoxical drug. The survival rate of the animals and the variations of their cerebral acetylcholinesterese activity are both reported as a function of the drug concentration, and with respect to their age. The collecting of the results may be described as the cusp, a bifurcation set of Thom's (...) Catastrophe Theory.The young animals react by a vital burst which modifies the shape of the cusp. A new fold or pocket takes place, changing it to the butterfly bifurcation set. This pocket supports the survival attractor concept, which appears reactional, transitory and variable in its intensity. (shrink)

In our post-9/11 environment, our sense of relative security and stability as privileged subjects living in the heart of Empire has been profoundly shaken. Hollander explores the forces that have brought us to this critical juncture, analyzing the role played by the neoliberal economic paradigm and conservative political agenda that emerged in the West over the past four decades with devastating consequences for the hemisphere's citizens. Narrative testimonies of progressive U.S. and Latin American psychoanalysts illuminate the psychological meanings of (...) living under authoritarian political conditions and show how a psychoanalysis "beyond the couch" contributes to social struggles on behalf of human rights and redistributive justice. By interrogating themes related to the mutual effects of social power and ideology, large group dynamics and unconscious fantasies, affects and defenses, Hollander encourages reflections about our experience as social/psychological subjects.

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 23 (2003) 3-19 [Access article in PDF] Some Reflections about Community and Survival Rita M. Gross University of Wisconsin-Eau Claire Many studies have indicated that at both ends of the life cycle human beings more readily survive and flourish if they experience significant contact with other humans, if they experience nurturing, love, and relationship. Having physical needs met, by itself, is not sufficient. Both infants and (...) old people, as well as people recovering from serious illness, are much more likely to survive if, in addition to having their physical needs met, they experience the emotional well-being brought about by sufficient companionship.Though the issue is less discussed, one wonders why things would be different in those phases of the life cycle in which one is seemingly more independent. How can adults flourish and thrive without sufficient companionship, love, and community? How do adults react to the absence of these important elements of life? I would suggest that relatively helpless infants, invalids, and aged people simply die, but adults have enough power and independence to react to their loneliness and frustration in ways that lash out at the social fabric that fails to love and nurture them sufficiently. In Buddhist psychology an organism's two most frequent reactions to stimulation are grasping at something or aggression toward it. I would suggest that unnurtured adults express their frustration with loneliness and lack of love precisely in those two ways. We have discussed these reactions in our previous sessions on war and on consumerism and its attendant environmental degradation.I agreed very reluctantly to write a paper for this session on community. I am reluctant for two reasons. First, I have already written on community, do not wish to repeat myself, and am not sure I have anything new to say. Thus, I end up with the option of being more personal in my reflections than I usually am. (I know some of you will think that could not be possible, because I always go too far on that score. My apologies.) Second, as a female academic and someone with no family who has been single most of my life, I know only too well the loneliness and frustration that come with living in a society with declining "social capital," to use the phrase so aptly employed by Robert Putnam in his book Bowling Alone. The topic is simply too painful for me, because I know intimately, by virtue of their absence in my life, the importance of companionship, friendship, and community. I appreciated all the [End Page 3] graphs and documentation in Putnam's book, but despite my many years of intense involvement in the Buddhist world, I already knew in my gut the main thesis of his book. Nevertheless, much of what I will write about in this paper is informed by Putnam's book, as well as by David Korten's The Post-Corporate World and bell hooks's All About Love, both of which I recommend as relevant reading materials as we prepare to discuss the topic of community.By contrast, for our first discussions of community in our 1987 meetings, I was eager to make a contribution. 1 I had discovered something, or so it seemed to me, that was both painful and important. In the early 1980s I began to realize that despite the energy and loyalty I brought to my Buddhist community, I was still lonely and was not experiencing the friendship, community, companionship, and support that seemed to me to be implied in the act of "going for refuge to the sangha. " Instead, people constantly told me that being alone was essential to Buddhist practice—a claim that I would contend has more to do withWestern notions of individualism and self-reliance than with Buddhism. Understandably, these values are especially strong among convert Buddhists, who had to defy convention and assert their individuality in the process of becoming Buddhists. Nevertheless, we were signing on to honor the refuge of sangha, not merely the refuges of Buddha and dharma, a point that is still underappreciated by many... (shrink)

This book pieces together the jigsaw puzzle of Einstein's journey to discovering the special theory of relativity. Between 1902 and 1905, Einstein sat in the Patent Office and may have made calculations on old pieces of paper that were once patent drafts. One can imagine Einstein trying to hide from his boss, writing notes on small sheets of paper, and, according to reports, seeing to it that the small sheets of paper on which he was writing would vanish into his (...) desk-drawer as soon as he heard footsteps approaching his door. He probably discarded many pieces of papers and calculations and flung them in the waste paper basket in the Patent Office. The end result was that Einstein published nothing regarding the special theory of relativity prior to 1905. For many years before 1905, he had been intensely concerned with the topic; in fact, he was busily working on the problem for seven or eight years prior to 1905. Unfortunately, there are no surviving notebooks and manuscripts, no notes and papers or other primary sources from this critical period to provide any information about the crucial steps that led Einstein to his great discovery. In May 1905, Henri Poincare sent three letters to Hendrik Lorentz at the same time that Einstein wrote his famous May 1905 letter to Conrad Habicht, promising him four works, of which the fourth one, Relativity, was a rough draft at that point. In the May 1905 letters to Lorentz, Poincare presented the basic equations of his 1905 "Dynamics of the Electron", meaning that, at this point, Poincare and Einstein both had drafts of papers relating to the principle of relativity. The book discusses Einstein's and Poincare's creativity and the process by which their ideas developed. The book also explores the misunderstandings and paradoxes apparent in the theory of relativity, and unravels the subtleties and creativity of Einstein. (shrink)

A theory of relativity, along with its appropriate group of Lorentz-type transformations, is presented. The theory is developed on a metric withR×S 3 topology as compared to ordinary relativity defined on the familiar Minkowskian metric. The proposed theory is neither the ordinary special theory of relativity (since it deals with noninertial coordinate systems) nor the general theory of relativity (since it is not a dynamical theory of gravitation). The theory predicts, among other things, that finite-mass particles in nature have maximum (...) rotational velocities, a prediction highly supported by recent experiments on 14 nuclei, such as 159 Yb that survives fission with angular velocities of up to 0.9 of the predicted value but does not reach it.

Einstein located the foundations of general relativity in simple and vivid physical principles: the principle of equivalence, an extended principle of relativity and Mach's principle. While these ideas played an important heuristic role in Einstein's thinking, they provide a dubious logical foundation for his final theory. Einstein was also guided to his final theory, I argue, by a second tier of more prosaic heuristics. I trace one strand among them. The principle of equivalence guided Einstein well until it led him (...) to a theory that contradicted the conservation of momentum. Einstein converted the requirement of conservation of energy and momentum into a procedure that he used repeatedly for finding gravitational field equations. That procedure survives in present day developments of general relativity. (shrink)

Nine selection‐survival strategies were implemented in a genetic algorithm experiment, and differences in terms of evolution were assessed. The moments of evolution (expressed as generation numbers) were recorded in a contingency of three strategies (i.e., proportional, tournament, and deterministic) for two moments (i.e., selection for crossover and mutation and survival for replacement). The experiment was conducted for the first 20,000 generations in 46 independent runs. The relative moments of evolution (where evolution was defined as a significant increase (...) in the determination coefficient relative to the previous generation) when any selection‐survival strategy was used fit a Log‐Pearson type III distribution. Moreover, when distributions were compared to one another, functional relationships were identified between the population parameters, revealing a degeneration of the Log‐Pearson type III distribution in a one‐parametrical distribution that can be assigned to the chosen variable—evolution strategy. The obtained theoretical population distribution allowed comparison of the selection‐survival strategies that were used. © 2012 Wiley Periodicals, Inc. Complexity, 2012. (shrink)

BackgroundThe need for an ethical debate about the use of coercion in intensive care units (ICU) may not be as obvious as in other areas of medicine, such as psychiatry. Coercive measures are often necessary to treat critically ill patients in the ICU. It is nevertheless important to keep these measures to a minimum in order to respect the dignity of patients and the cohesion of the clinical team. A deeper understanding of what patients and their relatives perceive during their (...) ICU stay will shed different light on intensive care management. Patients' experiences of loss of control, dependency and abandonment may lead to a new approach towards a broader approach to the concept of coercion in intensive care. The aim of our research is to explore the experiences of patients and relatives in the ICU and to determine when it might be possible to reduce feelings and memories of coercion.MethodsWe conducted and analysed 29 semi-structured interviews with patients and relatives who had been in the ICU a few months previously. Following a coding and categorisation process in MAXQDA™, a rigorous qualitative methodology was used to identify themes relevant to our research.ResultsFive main themes emerged: memory issues; interviewees’ experiences of restricting measures and coercive treatment; patients’ negative perception of situational and relational dependency with the risk of informal coercion; patients’ perceptions of good care in a context of perceived dependency; progression from perception of coercion and dependency to respect for the person. All patients were grateful to have survived. However, coercion in the form of restraint, restriction of movement, and coercive treatment in the ICU was also acknowledged by patients and relatives. These included elements of informal coercion beyond restraints, such as a perceived negative sense of dependence, surrender, and asymmetrical interaction between the patient and health providers.ConclusionsTo capture the full range of patients' experiences of coercion, it is necessary to expand the concept of coercion to include less obvious forms of informal coercion that may occur in dependency situations. This will help identify solutions to avoid or reduce negative recollections that may persist long after discharge and negatively affect the patients' quality of life. (shrink)

I ask three questions related to the claims made within the staying alive theory : Is survival more fitness-enhancing for females than for males? Does the historical record on sex differences in mortality support the SAT? Is it possible to talk about “independent selective pressures on both male and female traits” when all we have are sex/gender comparisons?

In a seminal and distinguished lecture published a little over thirty years ago, Sir Richard Southern examined the exercise of patronage as a means of government and as an instrument of social change in England in the reign of King Henry I. Focusing on the careers of some of the king's servants who rose in wealth and status by working in his administration, Southern elucidated their opportunities and methods of advancement, their rewards, and their manipulation of power and position to (...) bolster their local authority. In the years since Southern wrote, the important themes he opened up about these servants have been reexamined and developed by a number of scholars. These themes are further illuminated by the career of one of the most important of Henry's servants, Eustace Fitz John, lord of Malton and Alnwick, who rose from relatively obscure origins to a position of considerable prominence in the government of northern England. Eustace's career also tells us much about the means used by Henry I to complete and consolidate the Norman conquest of the north, integrate the region within the Norman system of government, and provide for its security and about the cross-border relationships of his northern administrators. A study of Eustace's career is additionally valuable because it throws light on many important aspects of the history of King Stephen's reign and the reign of Henry II. (shrink)

In cases of sudden, life-threatening illness where the chance of survival appears negligible to the admitting physician, this opinion is not always revealed during the initial meeting with the patient's relatives. Reasons as to why this withholding of the truth may be acceptable are explored through review of available evidence and personal reflection. Factors identified include: the importance of hope in families' coping mechanisms, and the instinct to preserve it; the fallibility of physicians' perception of poor prognosis in the (...) early phase of illness; the need to avoid large swings in relatives' expectations that occur when patients appear to rally during initial resuscitation; and the adverse effect that an atmosphere of hopelessness can have on the provision of medical care. A strategy for the staged disclosure of information and the confirmation of hopelessness is then described, the aim being to find a compromise between providing a true opinion about a patient's prognosis, and regard for the opposing factors described.

The de Broglie–Bohm interpretation is a no-collapse interpretation, which implies that we are in principle surrounded by empty waves generated by all particles of the universe, empty waves that will never collapse. It is common to establish an analogy between these pilot-waves and 3D radio-waves, which are nearly devoided of energy but carry nevertheless information to which we may have access after an amplification process. Here we show that this analogy is limited: if we consider empty waves in configuration space, (...) an effective collapse occurs when a detector clicks and the 3ND empty wave associated to a particle may not influence another particle (even if these two particles are identical, e.g. bosons as in the example considered here).

Earthquake emergency rescue work is one of the key construction works of disaster prevention and mitigation in China. This paper mainly studies the earthquake disaster rescue model based on the complex adaptive system theory and establishes the earthquake disaster rescue model by analyzing the complex adaptive system theory and combining the earthquake rescue process. In this paper, through (...) the task allocation mechanism task, the disaster rescue task is divided into simple task and complex task, and the executive task subject is divided into single task subject and multitask subject. On the basis of considering the shortest emergency rescue time goal and the goal of maximizing the deployment utility of rescue team, the reasonable deployment of a rescue team is realized through a complex adaptive system, that is, the deployment utility of the rescue team is maximized. In this paper, the simulation experiment and comparison of the earthquake disaster rescue model based on the complex adaptive system theory are carried out. The experimental results show that the model used in this paper is better than the other two models in terms of algorithm convergence, rescue number, and overall score; in different scenarios, the relative survival probability of the model in this paper is 58.92%, 67.85%, and 77.46%, and the proportion of the wounded rescued is 66.31%, 76.45%, and 83.06%, which were higher than those of the other two models. The earthquake disaster rescue model based on the complex adaptive system theory proposed in this paper provides an effective theoretical basis and method system for postdisaster emergency rescue decision making and enhances and improves the emergency response ability to deal with large-scale geological disaster events.

The effects of grandparent survival on child survival and mean interbirth interval, both independent of and relative to parent survival, were investigated in a historical population. Families for the data set were reconstituted from the parish and census records of Cambridgeshire, 1770–1861. In a logistic regression analysis, only the mother’s and the maternal grandmother’s survival were found to be significant predictors of child survival. Maternal grandmother’s survival was found to influence child survival (...) both via maternal survival and independent of maternal survival. Grandparent survival was not found to influence mean interbirth interval. These findings are reviewed with respect to other studies of grandmothering, the Grandmother Hypothesis, and the evolutionary significance of human female postreproductive lifespan. (shrink)

: Accidents will survive the outbreak of driverless cars, but their moral implications will suffer substantial changes. The decision made today by a human in a fraction of a second will eventually be replaced by an algorithm subject to moral scrutiny. This not only raises the question of how the algorithm should work, or whether alternatives solutions are indeed comparable, but also changes the essence of the problem: from ascertaining liability to defining desired outcomes. In this paper, I first contest (...) two possible approaches to resolving the driverless car dilemma – which I call statistical and nominal – to conclude that neither is morally sound. I then propose an alternative solution based on “time-relative equality”, or always sparing younger people. This follows from seeking an egalitarian solution, that is the least intrusive – a position I defend from a possible ageist critique. Keywords: Driverless Cars; Accident; Algorithm; Age-relative Equality Condotti verso un incidente morale Riassunto: Vi saranno incidenti anche dopo la diffusione delle auto a guida autonoma, ma le loro implicazioni morali subiranno mutamenti sostanziali. Le decisioni prese oggi in una frazione di secondo dagli esseri umani saranno alla fine sostituite da un algoritmo soggetto a controllo morale. Sorge non solo il problema di come dovrebbe funzionare questo algoritmo – o se vi siano soluzioni alternative comparabili –, ma cambia anche la sostanza del problema: dall’accertamento dell’imputabilità alla definizione dell’esito auspicato. In questo lavoro discuterò due possibili approcci per risolvere il dilemma – che chiamerò “statistico” e “nominale” –, per concluderne che non sono moralmente corretti. Proporrò quindi una soluzione alternativa, basata sulla “eguaglianza tempo-relativa”, il principio per cui bisogna sempre salvare il più giovane. Questo segue dal cercare una soluzione egalitarista, che sia la meno intrusiva – una posizione che difenderò da una possibile critica che la vede come discriminatoria verso gli anziani. Parole chiave: Automobili a guida automatica; Incidenti; Algoritmo; Eguaglianza relativa all’età. (shrink)

Rapid changes in the ways of survival in human societies, passing quickly from pre-industrial to industrial societies or industrial societies to knowledge societies, characterized by innovation and constant change, require a kind of a non religious spirituality not tied to beliefs. No need to go to Eastern spiritual traditions, Buddhism, Yoga or Advaita Vedanta to show and experience the possibility of a non-religious spirituality; also within the Christian tradition, we find authors that allow non-religious spirituality. We can count on (...) an important notion of Nicholas of Cusa: The "No-Other" as the absolute dimension of all reality. The Cusano considers that this term is more appropriate to describe that absolute of all reality then the term God. It is also very convenient to live a spirituality that does not divide reality into two poles: the mundane and the divine, the relative and absolute in this world and the next. (shrink)

The House Sparrow (Passer domesticus), formerly a common bird species, has shown a rapid decline in Western Europe over recent decades. In The Netherlands, its decline is apparent from 1990 onwards. Many causes for this decline have been suggested that all decrease the vital rates, i.e. survival and reproduction, but their actual impact remains unknown. Although the House Sparrow has been dominant in The Netherlands, data on life history characteristics for this bird species are scarce: data on reproduction are (...) non-existent, and here we first present survival estimates based on live encounters and dead recoveries of marked individuals over the period 1976–2003, 14 years before and 14 years during the decline, reported to the Dutch Ringing Centre. We show that there is an indication that both juvenile and adult survival are lower during the period of decline. -/- Secondly, to be able to analyse the relative impact of changes in the vital rates, we formulated a general matrix model based on a range of survival values between zero and one with a step size of 0.01 (both juvenile and adult yearly survival) and a range of realistic reproduction values (one, three or five fledglings per pair per year). With the matrix model, we calculated the finite rate of population change (λ) and applied elasticity analysis. To diagnose the cause of the decline in the Dutch House Sparrow, we parameterised the model with estimates of survival values before and during the decline and present the resulting λ. With the survival estimates from the declining period, λ < 1 only if reproduction is relatively low. We discuss this result within the light of available literature data on survival in the House Sparrow. Finally, we evaluate which of the suggested causes of population decline should be reversed to mitigate the decline and how this can be achieved. (shrink)

Religion persists, even within enlightened secular society, because it has adaptive functions. In particular, Ralph Wendell Burhoe's theory holds that religion is the repository of cultural wisdom that most encourages mutual altruism among nonkin, long-term social survival, and human progress. This article suggests a variant of Burhoe's rationalized naturalistic view. Cognitive theism is a proposal that secularists sometimes take religion on its own terms by suspending disbelief about God. If we consider particular human capacities and limitations in memory, perception, (...) personality, and motivation, the regulated “mind expansion” of cognitive theism may help us to evaluate, coordinate, and invigorate things in a modern environment. In this environment, communicative and travel technologies have led to a high loading of consciousness with a historically unusual diverse range of experiences and responsibilities, a high rate of cultural change relative to biological evolution, and a tendency to factionalize. Burhoe's extension of the concept of symbiosis to the coevolution of culture and genes is modified here in recognition of individual differences and of individuals' potential for choosing strategies, recombining in groups, and learning. In human biocultural symbiont pools, cultural phenomena can evolve while changing partners in a dance with genetic substrates, a dance that broadly supports these substrates. In the context of diversity and incessant change in a large predominantly secular community, Judeo-Christian monotheism can have a valuable advisory unifying function. (shrink)

To ensure their survival in natural habitats, plants must recognize and respond to a wide variety of insect herbivores. Aphids and other Hemiptera pose a particular challenge, because they cause relatively little direct tissue damage when inserting their slender stylets intercellularly to feed from the phloem sieve elements. Plant responses to this unusual feeding strategy almost certainly include recognition of aphid salivary components and the induction of phloem‐specific defenses. Due to the excellent genetic and genomic resources that are available (...) for Arabidopsis thaliana (Arabidopsis), this plant was chosen as a model system to study the metabolic and transcriptional responses to infestation by two aphids, Myzus persicae (green peach aphid, a broad generalist) and Brevicoryne brassicae (cabbage aphid, a crucifer‐feeding specialist). Future research on Arabidopsis–aphid interactions will lead to the identification of aphid‐specific elicitors, components of the defense‐signaling pathway, and additional metabolic responses that are induced by aphid infestation.

In European philosophies of history, the linear paradigm that has prevailed for centuries as a derivative of Christian salvation history (Heilsgeschichte), ultimately lost its monopoly with the arrival of the “post-age.” The result of this has been that ideas that have survived on the margins, even the cyclical interpretation of time attached to religious traditions, now seem capable of outliving the short-lived belief in continuous progress. According to the cyclical view of history, those who came last will leave first, with (...) those who came first leaving as the last adherents of the driving force of Western rationalization. Thus, within a century, beginning with World War 2, a major turning point has been crossed: Socialism was the first to disappear, and it looks like Secular Liberalism will be the next; then Protestantism, followed by Islam, and so forth. As seductive as these images may appear, they only mirror an auto-destructive thread at the very center of Europe’s troubled Geist. But can anything be done to save the most important European values, and specifically, the ethical drive to say “no” to power, which is perhaps the most important legacy of monotheism? Either as a self-limitation from within powerful institutions or as a mode of resistance on the margins of powerful developments—there is a strong adherence to the good (often named God) that helps people and communities survive their diasporic state. I will present this kernel of ethical monotheism by two relatively unknown twentieth-century examples of “diasporic knowledge”: Rebecca West’s Black Lamb and Grey Falcon (1941), in which she recorded her observations of the devastating effects of empires on Yugoslavia, and two poems by Rosario Castellanos, who decades before the debate on postcolonialism voiced the concerns of displaced indigenous cultures in her Mexican homeland. I suggest that, paradoxically, attention to diasporic voices is one way of realizing the spirit of European self-limitation that is so much needed today to prevent further damage to our societies and environment wrought by the excessive drive for progress fostered by an unethical monorationalism.

Cochlear implants electrically stimulate surviving auditory neurons in the cochlea to provide severely or profoundly deaf people with access to hearing. Signal processing strategies derive frequency-specific information from the acoustic signal and code amplitude changes in frequency bands onto amplitude changes of current pulses emitted by the tonotopically arranged intracochlear electrodes. This article first describes how parameters of the electrical stimulation influence the loudness evoked and then summarizes two different phenomenological models developed by McKay and colleagues that have been used (...) to explain psychophysical effects of stimulus parameters on loudness, detection, and modulation detection. The Temporal Model is applied to single-electrode stimuli and integrates cochlear neural excitation using a central temporal integration window analogous to that used in models of normal hearing. Perceptual decisions are made using decision criteria applied to the output of the integrator. By fitting the model parameters to a variety of psychophysical data, inferences can be made about how electrical stimulus parameters influence neural excitation in the cochlea. The Detailed Model is applied to multi-electrode stimuli, and includes effects of electrode interaction at a cochlear level and a transform between integrated excitation and specific loudness. The Practical Method of loudness estimation is a simplification of the Detailed Model and can be used to estimate the relative loudness of any multi-electrode pulsatile stimuli without the need to model excitation at the cochlear level. Clinical applications of these models to novel sound processing strategies are described. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Considering AnimalsKheel's Nature Ethics and Animal Debates in EcofeminismNoël Sturgeon (bio)How we treat the use of animals by humans for sport, experimentation or food has been controversial within ecofeminism. While it is fair to say that all ecofeminists agree that factory farming and cruel treatment of animals is morally wrong, universal arguments for vegetarianism or veganism have been, if one forgives the metaphor, a bone of contention. Attached to (...) these disagreements are important philosophical and political debates about ecological holism, individualistic frameworks, cultural difference, social privilege and ethics of care, which are consequential above and beyond evaluating our treatment of animals. Thus, ecofeminist discussions of animal issues have been formative for environmental ethics and politics, while remaining a delicate matter when disagreement occurs among a relatively small group of thinkers, activists and scholars who tend towards solidarity.Val Plumwood, the important Australian philosopher whose work and life are celebrated in this volume, was especially cognizant of all of this. In April 1998, Plumwood presented an early version of what became two articles on animal/human relationships (Plumwood 1999, 2000) at the Ecofeminist Perspectives Conference at the University of Montana. [End Page 153] The presentation, which occurred early in the conference, was, typical of Plumwood, straightforwardly contentious, a bold challenge to the position of some ecofeminists at the time that veganism was the only morally acceptable diet. In it, she suggested that what she called "ontological veganism" was a position that was both culturally ethnocentric and dualistic, two accusations guaranteed to deeply disturb this particular audience. The conference, organized by Deborah Slicer (whose 1996 article, "Your Daughter or Your Dog?" argued against animal experimentation), was also attended by Marti Kheel (who, along with Carol Adams, was an early proponent of "ontological veganism"). Present also were thinkers with more nuanced positions on the issue, such as Lori Gruen, Greta Gaard, and Karen Warren. Thus, Plumwood's provocation felt personal, and produced lively debate at the conference, and an even livelier argument on email afterwards.1 Stung by being portrayed as racist, several ecofeminists reacted with anger at Plumwood, with the result that she publicly rejected the label "ecofeminist," and from then until her untimely death, preferred the category "critical feminist eco-socialism" to describe her framework.Despite the hurt feelings, this debate (and Plumwood's subsequent articles and sections in her 2002 book, Environmental Culture: The Ecological Crisis of Reason), moved ecofeminist treatment of the issues of animals and morally sound eating practices considerably forward. Plumwood argued that to avoid the dualism of human/nature, humans should recognize themselves as prey as well as predator, an approach she brilliantly portrayed in her article on the experience of surviving a crocodile attack. (Plumwood 1995) In her view, any position that eliminated the possibility of using some animals as food necessarily relied upon a rights-based, individualistic approach that retained the status of some living beings as excluded from moral consideration. Yet, Plumwood argued, from a contextualized moral position, which respected both continuity and difference between different groups of living beings, one could make ethical claims about the moral problems of eating animals. She was particularly interested, both philosophically and from a politically strategic perspective, in arguing against the practice of factory farming. Karen Warren, in her book Ecofeminist Philosophy (2000), also followed and expanded Plumwood's discussion by emphasizing the advantages of a contextualized ethic of care in the treatment of animals as food, arguing (and as such agreeing with Plumwood's conference presentation), that it was ethnocentric [End Page 154] to insist on universal standards in evaluating whether some cultural groups, such as the Inuit, could morally refrain from eating animals. Greta Gaard's thoughtful article on the indigenous Makah whale hunt (2001) took on the charge of ethnocentrism directly, as in some ways an answer to Plumwood's provocation.Given this background, it is interesting to read Marti Kheel's important new book and see how her promotion of veganism as a moral position is articulated. A longtime feminist, vegan, and animal advocate, Kheel is a co-founder of the activist group Feminists for Animal Rights, and the author of an important early critique of deep... (shrink)

This volume covers a relatively short span of time, rather less than the first three-quarters of the first century BC; but it was an age of profoundly important developments, with enduring consequences for the subsequent history of Latin literature. Original and innovative in widely differing ways as was the work of Lucretius, Sallust and Caesar in particular, the scene is dominated, historically, by two figures: Cicero and Catullus. Cicero was a politician and a man of affairs as well as a (...) man of latters, whose vast literary output reflects a range of intellectual interests unparalleled among surviving Roman writers; creator of a prose style the Quintilian regarded as synonymous with eloquence itself; and better known to us, from his letters, as a human being, than any other figure from classical antiquity. Catullus was a poet, single-mindedly devoted to fostering the tradition of learned Alexandrian poetry at Rome; the author of one slender volume of verse that has attracted more critical attention in proportion to its size than any other ancient poetry-book; and the lover of Lesbia. In these chapters it is shown how these, and other, Roman writers of genius continued the process of transforming their traditional Greek models into new and vigorous Latin forms, with lasting effects for oratory, historiography, and the higher genres of poetry.

Barely a decade after the discovery of the chromosomal basis of inheritance, and the articulation of the genetical theory of population change, the gene came to be widely regarded as the fundamental unit of biological organization. This is hardly surprising. The gene concept is a powerful one; it plays a unifying role in our understanding of evolution. Darwin told us that evolution by natural selection occurs in a population when organisms survive, die and reproduce differentially on account of their heritable (...) form. This is a very schematic theory. It requires an account of the process of inheritance and also an account of the generation of phenotype. The gene concept plays a prominent role in explaining, and uniting, these phenomena. Genes are the units of inheritance; they are passed from parents to offspring in reproduction. Moreover, they are seen as units of phenotypic control. Evolutionary biologists often speak of the genome as a program for the production of an organism. Genes also became the elements of which populations are composed. Our best theory of population dynamics—inherited from Fisher, Haldane, and Wright—is a theory of changes in the relative frequencies of gene types. Genes are not just the principal causes of evolutionary change, they are also the units over which evolutionary change is defined and measured. So, at least, the orthodox reading of the Modern Synthesis theory of evolution would have us believe... (shrink)

Alone among surviving Athenian homicide orations, Antiphon's On the Murder of Herodes resembles a modern murder mystery. Antiphon's client, a Mytilenean named Euxitheus, tells a story of a stormy night, an isolated harbour, a drunken murder victim, a missing corpse, misleading bloodstains, forged documents and hints of political intrigue. And, like in any good whodunnit, Euxitheus insists that no one knows who the killer is. Although all the clues seem to point to him, he maintains that Herodes' relatives have manipulated (...) the evidence to make him seem guilty. We do not know whether Euxitheus succeeded in convincing his jurors, but the author of the Life of Antiphon attributed to Plutarch, who says that Antiphon was ‘adept in situations with no way out’, considers On the Murder of Herodes one of Antiphon's finest compositions.

This paper sketches a taxonomy of forms of substantivalism and relationism concerning space and time, and of the traditional arguments for these positions. Several natural sorts of relationism are able to account for Newton's bucket experiment. Conversely, appropriately constructed substantivalism can survive Leibniz's critique, a fact which has been obscured by the conflation of two of Leibniz's arguments. The form of relationism appropriate to the Special Theory of Relativity is also able to evade the problems raised by Field. I survey (...) the effect of the General Theory of Relativity and of plenism on these considerations. (shrink)

In the last 60,000 years humans have expanded across the globe and now occupy a wider range than any other terrestrial species. Our ability to successfully adapt to such a diverse range of habitats is often explained in terms of our cognitive ability. Humans have relatively bigger brains and more computing power than other animals and this allows us to figure out how to live in a wide range of environments. Here we argue that humans may be smarter than other (...) creatures, but none of us is nearly smart enough to acquire all of the information necessary to survive in any single habitat. In even the simplest foraging societies, people depend on a vast array of tools, detailed bodies of local knowledge, and complex social arrangements, and often do not understand why these tools, beliefs, and behaviors are adaptive. We owe our success to our uniquely-developed ability to learn from others. This capacity enables humans to gradually accumulate information across generations, and develop well-adapted tools, beliefs, and practices that are too complex for any single individual to invent during their lifetime.

Some ‘naturalist’ accounts of disease employ a biostatistical account of dysfunction, whilst others use a ‘selected effect’ account. Several recent authors have argued that the biostatistical account offers the best hope for a naturalist account of disease. We show that the selected effect account survives the criticisms levelled by these authors relatively unscathed, and has significant advantages over the BST. Moreover, unlike the BST, it has a strong theoretical rationale and can provide substantive reasons to decide difficult cases. This is (...) illustrated by showing how life-history theory clarifies the status of so-called diseases of old age.

ABSTRACT The philosophical tradition approaches to morals have their grounds predominantly on metaphysical and theological concepts and theories. Among the traditional ethics concepts, the most prominent is the Divine Command Theory (DCT). As per the DCT, God gives moral foundations to the humankind by its creation and through Revelation. Morality and Divinity are inseparable since the most remote civilization. These concepts submerge in a theological framework and are largely accepted by most followers of the three Abrahamic traditions: Judaism, Christianity, and (...) Islam: the greatest part of the human population. Holding faith and Revelation for its grounds, the Divine Command Theories are not strictly subject to the demonstration. The opponents to the Divine Command conception of morals, grounded in the impossibility of demonstration of its metaphysical and religious assumptions, have tried for many centuries (albeit unsuccessfully) to devalue its importance. They held the argument that it does not show material evidence and logical coherence and, for this reason, cannot be taken into account for scientific nor philosophical purposes. It is just a belief and, as so, should be understood. Besides these extreme oppositions, many other concepts contravene the Divine Command theories, in one or another way, in part or in full. Many philosophers and social scientists, from the classic Greek philosophy up to the present date, for instance, sustain that morality is only a construct, and thus culturally relative and culturally determined. However, this brings many other discussions and imposes the challenge to determine what is the meaning of culture, which elements of culture are morally determinant, and finally, what are the boundaries of such relativity. Moral determinists claim that everything related to human behavior, including morality, is determined, once free will does not exist. More recently, modern thinkers argued that there is a strict science of morality. However, the scientific method alone, despite explaining several facts and evidence, cannot enlighten the entire content and full meaning of ethics. Morals’ understanding requires a broader perception, and an agreement among philosophers, which they have never achieved. All of these questions have many different configurations depending on each philosophical strand, and start complex analysis and endless debates, as long as many of them are reciprocally conflictive. The universe and the atmosphere involving this thesis are the dominions of all these conceptual conflicts, observed from an objective and evolutionary standpoint. Irrespective of this circumstance and its intrinsic importance, however, these questions are far distant from the methodological approach of an analytical discussion on objective morals, what is, indeed, the aim and scope of this work. We should briefly revisit these prominent traditional theories because this thesis shelters a comparative study, and its assumptions at least differ profoundly from all traditional theories. Therefore, it becomes necessary offering direct and specific elements of comparison to the reader, for the right criticism, dispensing interruptive researches. However, even revisiting the traditional theories, for this comparative and critical exposure purpose, they will be kept by the side of our main concerns, as “aliena materia.” Irrespective of the validity of any or all of the elements of this discussion, and their meaning as the philosophical universe of this thesis, the purpose of this work is demonstrating and justifying the existence and meaning of prehistoric moral archetypes arisen directly from the very first social needs and efforts for survival. These archetypes are the definition of the essential foundation of ethics, its aggregation to the collective unconscious and corresponding logic organization and transmission to evolutionary stages of the human genome and different relations space-time, irrespective of any contemporary experience of the individuals. The system defined by these archetypes composes an evolutionary human social model. Is this a metaethical position? Yes, it is. Moreover, as in any metaethical reasoning, we should look carefully for the best and coherent routes, as the Analytical Philosophy offers them. Thus, this work should reasonably demonstrate that morals are not a cultural product of the civilized men or modern societies and that despite being subject to several cultural relative aggregations and subtractions, its essential foundations are archetypal and have never structurally changed. This reasoning induces that morality is an original attribute of the “homo sapiens”; it is not a property and nor an accident: it integrates the human essence and belongs to the realm of the ontological human identity. The human phenomena is a continuing process, playing its role between random determination and free will, and we need to question how morality began and how did it come to us in the present.

Death is the destiny we all share, and this will not change. Yet the way we die, which had remained the same for many generations, has changed drastically in a relatively short time for those in developed countries with access to healthcare. For generations, if people were lucky enough to reach old age, not having died in infancy or childhood, in childbirth, in war, or by accident, they would take to bed, surrounded by loved ones who cared for them, and (...) fade into death. Most likely, they would have seen their parents and grandparents die the same way, and so this manner of dying would be familiar: it was part of the natural cycle of life. Now less than 25 per cent of Americans die at home, having reached much older ages than people would have dreamed of in past generations, often after surviving many illnesses and even diseases that would have been terminal for their grandparents. We are fortunate to live (and die) today, supported by myriad scientific, medical, and technological advancements, however we also face new problems as a result of the new way in which we die. We can no longer anticipate a peaceful waning at home with family. We know our lives will likely end in hospitals likely after we have endured grueling treatments to prolong life. We have to decide what decisions we want our loved ones, or care-givers, to make when we cannot choose for ourselves. We have to think about whether in any circumstances we would seek physician-assisted death. We know we face other questions as well, but we may not even know where to start. In the face of these decisions, we can feel daunted and afraid. The best remedy is information and planning. In this book, Gregory Eastwood - a physician who has cared for dying patients, served as an ethics consultant, and taught end of life issues to medical and other health profession students - draws from his substantial experience with patients and families to provide the information that will help us think clearly about the choices and issues we will face at the end of our own lives, and when faced with the deaths of our loved ones. With sensitivity and profound insight, Eastwood guides us through all the important questions about death and dying in straightforward, clear language, enhanced by real-life stories. Throughout, he shows us how we can take ownership of the way we want to die, when we must die, and feel more in control as death approaches. (shrink)

According to an almost axiomatic standard in bioethics, moral commitment should ground parents’ relationship with their children, rather than biogenetic relatedness. This standard has been used lately to express skepticism about extending existing assisted reproductive treatments (ARTs) to same‐sex couples and to research into novel fertility interventions for those couples, but this skepticism is misplaced on several grounds. As a matter of access and equity, same‐sex couples seem presumptively entitled to genetic relatedness to their children as far as possible both (...) in regard to existing ARTs and to novel ARTs under investigation. For those worried about the effects of trying to secure biogenetic relatedness for same‐sex couples, it may be noted that same‐sex couples will only ever be a fraction of the parents implicated in propping up “biologism,” as the expectation of biogenetic relatedness it is sometimes called. The cultural force of biologism would survive almost intact even if no same‐sex couples were ever to have genetically related children. It is therefore hard to see why same‐sex couples should forfeit aspirations to biogenetic relationships with their children or enjoy less subsidy for ARTs than the subsidy given to different‐sex couples. As matter of moral consistency, the full implications of the biologism critique have yet to be evaluated relative to different‐sex couples. (shrink)
