The philosophy of Wittgenstein is both novel and enigmatic. What is his new revolutionizing methodology? What is his aim, his purpose, his intention? What does he mean by the puzzling terms ‘forms of life’, ‘language-games’, ‘seeing as’? The key to the answers, according to the thesis of this paper, lies in Wittgenstein’s conception of the ‘Weltanschauung’. By the explanation of the use of this term, the entire philosophy of Wittgenstein may become illuminated with new meaning and interpretation. In understanding the (...) meaning of the word ‘Weltanschauung’ we shall come to understand why Wittgenstein used his new method, just what that method was, and what the impact of the concept and method had on the terms ‘Language-game’, ‘forms of life’ and ‘seeing as’.

In [3], two different effective versions of Borel embedding are defined. The first, called computable embedding, is based on uniform enumeration reducibility, while the second, called Turing computable embedding, is based on uniform Turing reducibility. While [3] focused mainly on computable embeddings, the present paper considers Turing computable embeddings. Although the two notions are not equivalent, we can show that they behave alike on the mathematically interesting classes chosen for investigation in [3]. We give a “Pull-back Theorem”, saying that if (...) Φ is a Turing computable embedding of K into K’, then for any computable infinitary sentence φ in the language of K’, we can find a computable infinitary sentence φ* in the language of K such that for all.

Here we prove that if T and T′ are strongly minimal theories, where T′ satisfies a certain property related to triviality and T does not, and T′ is model complete, then there is no computable embedding of Mod(T) into Mod(T′). Using this, we answer a question from [4], showing that there is no computable embedding of VS into ZS, where VS is the class of infinite vector spaces over Q, and ZS is the class of models of Th(Z, S). Similarly, (...) we show that there is no computable embedding of ACF into ZS, where ACF is the class of algebraically closed fields of characteristic 0. (shrink)

First published in 2002. Routledge is an imprint of Taylor & Francis, an informa company.

In his “Theology and Falsification” Professor Antony Flew challenges the sophisticated religious believer to state under what conceivable occurrences he would concede that there really is no God Who loves mankind: ‘Just what would have to happen not merely to tempt but also, logically and rightly, to entitle us to say “God does not love us” or even “God does not exist”? I therefore put…the simple central questions, “What would have to occur or to have occurred to constitute for you (...) a disproof of the love of, or of the existence of, God”?’. (shrink)

The use of upper limb vibration during exercise and rehabilitation continues to gain popularity as a modality to improve function and performance. Currently, a lack of knowledge of the pathways being altered during ULV limits its effective implementation. Therefore, the aim of this study was to investigate whether indirect ULV modulates transmission along spinal and corticospinal pathways that control the human forearm. All measures were assessed under CONTROL and ULV conditions while participants maintained a small contraction of the right flexor (...) carpi radialis muscle. To assess spinal pathways, Hoffmann reflexes elicited by stimulation of the median nerve were recorded from FCR with motor response amplitudes matched between conditions. An H-reflex conditioning paradigm was also used to assess changes in presynaptic inhibition by stimulating the superficial radial nerve 37 ms prior to median nerve stimulation. Cutaneous reflexes in FCR elicited by stimulation of the SR nerve at the wrist were also recorded. To assess corticospinal pathways, motor evoked potentials elicited by transcranial magnetic stimulation of the contralateral motor cortex were recorded from the right FCR and biceps brachii. ULV significantly reduced H-reflex amplitude by 15.7% for both conditioned and unconditioned reflexes. Therefore, ULV inhibits cutaneous and H-reflex transmission without influencing corticospinal excitability of the forearm flexors suggesting increased presynaptic inhibition of afferent transmission as a likely mechanism. A general increase in inhibition of spinal pathways with ULV may have important implications for improving rehabilitation for individuals with spasticity. (shrink)

Transplantation of vital organs has been premised ethically and legally on "the dead donor rule" (DDR)—the requirement that donors are determined to be dead before these organs are procured. Nevertheless, scholars have argued cogently that donors of vital organs, including those diagnosed as "brain dead" and those declared dead according to cardiopulmonary criteria, are not in fact dead at the time that vital organs are being procured. In this article, we challenge the normative rationale for the DDR by rejecting the (...) underlying premise that it is necessarily wrong for physicians to cause the death of patients and the claim that abandoning this rule would exploit vulnerable patients. We contend that it is ethical to procure vital organs from living patients sustained on life support prior to treatment withdrawal, provided that there is valid consent for both withdrawing treatment and organ donation. However, the conservatism of medical ethics and practical concerns make it doubtful that the DDR will be abandoned in the near future. This leaves the current practice of organ transplantation based on the "moral fiction" that donors are dead when vital organs are procured. (shrink)

Risk–benefit assessment is a routine requirement for research ethics committees that review and oversee biomedical research with human subjects. Nevertheless, it remains unclear how to weigh and balance risks to research participants against the social benefits that flow from generating biomedical knowledge. In this article, we address the question of whether there are any reasonable criteria for defining the limit of permissible risks to individuals who provide informed consent for research participation. We argue against any a priori limit to permissible (...) research risks. However, attention to the uncertainty of potential social benefit that can be derived from any particular study warrants caution in exposing prospective research participants to a substantial likelihood of serious harm.

Many research ethics guidelines now oblige researchers to offer research participants the results of research in which they participated. This practice is intended to uphold respect for persons and ensure that participants are not treated as mere means to an end. Yet some scholars have begun to question a generalised duty to disclose research results, highlighting the potential harms arising from disclosure and questioning the ethical justification for a duty to disclose, especially with respect to individual results. In support of (...) this view, we argue that current rationales for a duty of disclosure do not form an adequate basis for an ethical imperative. We review policy guidance and scholarly commentary regarding the duty to communicate the results of biomedical, epidemiological and genetic research to research participants and show that there is wide variation in opinion regarding what should be disclosed and under what circumstance. Moreover, we argue that there is fundamental confusion about the notion of “research results,” specifically regarding three core concepts: the distinction between aggregate and individual results, amongst different types of research, and across different degrees of result veracity. Even where policy guidance and scholarly commentary have been most forceful in support of an ethical imperative to disclose research results, ambiguity regarding what is to be disclosed confounds ethical action.

Despite strong growth in scientific investigation of the placebo effect, understanding of this phenomenon remains deeply confused. We investigate critically seven common conceptual distinctions that impede clear understanding of the placebo effect: (1) verum/placebo, (2) active/inactive, (3) signal/noise, (4) specific/nonspecific, (5) objective/subjective, (6) disease/illness, and (7) intervention/context. We argue that some of these should be eliminated entirely, whereas others must be used with caution to avoid bias. Clearing away the conceptual underbrush is needed to lay down a path to understanding (...) and harnessing placebo effects in clinical medicine. (shrink)

Although established in the law and current practice, the determination of death according to neurological criteria continues to be controversial. Some scholars have advocated return to the traditional circulatory and respiratory criteria for determining death because individuals diagnosed as ‘brain dead’ display an extensive range of integrated biological functioning with the aid of mechanical ventilation. Others have attempted to refute this stance by appealing to the analogy between decapitation and brain death. Since a decapitated animal is obviously dead, and ‘brain (...) death’ represents physiological decapitation, brain dead individuals must be dead. In this article we refute this ‘decapitation gambit.’ We argue that decapitated animals are not necessarily dead, and that, moreover, the analogy between decapitation and the clinical syndrome of brain death is flawed.

Good work in nursing is work that is scientifically effective as well as morally and socially responsible. The purpose of this study was to examine variables that sustain good work among entering nurses (with one to five years of experience) and experienced professional nurses despite the obstacles they encounter. In addition to role models and mentors, entering and experienced nurses identified team work, cohesiveness and shared values as levers for good work. These nurses used prioritization, team building and contemplative practices (...) to overcome obstacles. Entering professional nurses tended to avoid conflict in the work setting. Experienced nurses reported forming teams of decision makers who share similar values to resolve conflict. These findings have implications for nurse education and nursing practice. Reflection on the importance of values and virtue in sustaining good work is important. Entering professional nurses should be encouraged to seek positive role models and reflect on the lessons that can be learned from experienced exemplary nurses. (shrink)

A growing body of literature places blame for accounting frauds on the failure of educators to implement ethics training in accounting curriculums in higher educational institutions. Although, the professional accountancy bodies in the UK espouse high ethical standards, others suggest that these bodies are failing to cover ethics in any meaningful way. This study surveys faculty about what is being taught and how much time is dedicated to ethics training. This is the first study to examine whether content suggested by (...) the Ethics Education Framework has been implemented in curriculums in the UK. In addition, we look to determine if there is a notable difference between what is covered in both pre-1992 and post-1992 UK universities. Although we find that post-1992 institutions have implemented the EEF suggestions more than pre-1992 UK universities, current ethics training is insufficient and has not changed much over the last two decades.

Background: Expanded newborn screening generates incidental results, notably carrier results. Yet newborn screening programmes typically restrict parental choice regarding receipt of this non-health serving genetic information. Healthcare providers play a key role in educating families or caring for screened infants and have strong beliefs about the management of incidental results. Methods: To inform policy on disclosure of infant sickle cell disorder (SCD) carrier results, a mixed-methods study of healthcare providers was conducted in Ontario, Canada, to understand attitudes regarding result management (...) using a cross-sectional survey (N = 1615) and semistructured interviews (N = 42). Results: Agreement to reasons favouring disclosure of SCD carrier results was high (65.1%–92.7%) and to reasons opposing disclosure was low (4.1%–18.1%). Genetics professionals expressed less support for arguments favouring disclosure (35.3%–78.8%), and more agreement with arguments opposing disclosure (15.7%–51.9%). A slim majority of genetics professionals (51.9%) agreed that a reason to avoid disclosure was the importance of allowing the child to decide to receive results. Qualitatively, there was a perceived “duty” to disclose, that if the clinician possessed the information, the clinician could not withhold it. Discussion: While a majority of respondents perceived a duty to disclose the incidental results of newborn screening, the policy implications of these attitudes are not obvious. In particular, policy must balance descriptive ethics (ie, what providers believe) and normative ethics (ie, what duty-based principles oblige), address dissenting opinion and consider the relevance of moral principles grounded in clinical obligations for public health initiatives.

In this essay we argue that the current social and ethical structure in the Open Source Software Community stem from its roots in academia. The individual developers experience a level of autonomy similar to that of a faculty member. Furthermore, we assert that the Open Source Software Community’s social structure demands benevolent leadership. We argue that it is difficult to pass off low quality open source software as high quality software and that the Open Source development model offers strong accountability. (...) Finally, we argue that Open Source Software introduces ethical challenges for universities and the software development community. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Triumphus in PalatioJohn F. MillerAs one of the many tokens of its symbolic centrality in Roman culture, the Capitoline Hill received the triumphator at the end of his ceremonial return to Rome. For centuries generals who had been granted a triumphus concluded the elaborate sacral procession through the city with a sacrifice at the Temple of Jupiter Optimus Maximus, the god most intimately associated with this religious institution.1 The (...) strongly local character of Roman cults made it nearly unthinkable to celebrate the solemn event anywhere else in Rome, but artistic imagination feels itself less bound by religious scruples. Two such ingenious revisions of the triumphal parade displace its endpoint to the Temple of Apollo on the Palatine Hill. Virgil imagines Octavian's great triple triumph of 29 B.C. taking place there, while other ancient evidence leads us to believe that the victor really proceeded to the Capitoline like countless imperatores triumphantes before him.2 The poet sets the celebration at the shrine of the deity credited with the victory at Actium, the shrine which Octavian built adjacent to his own house. The Palatine was becoming the imperial palace complex, the triumph a prerogative of the imperial family.3 When these developments had been fully realized, Nero in December A.D. 674 staged an eccentric victory procession which likewise climaxed at Apollo's Palatine temple. As returning victor in the festivals [End Page 409] of Greece he aimed to align himself with Apollo as patron of the arts, expressing now in topographical terms his frequent association with that deity.5 The lyre-playing god greeted the lyre-playing emperor, and vice versa. On the other hand, it is not irrelevant that one whom Pliny termed imperator scaenicus, "an actor-emperor" (Pan. 46.4), rode in the path of Virgil's fictional Augustus. The present essay explores the phenomenon triumphus in Palatio by explicating the two instances in the light of their ideological impulses. A further aim is to throw into relief the Augustan dimensions of Nero's triumphal ceremony, to show how the emperor in effect acted the part of Octavian riding in triple triumph.On the shield in Aeneid 8 Virgil inventively describes the triple triumph which Octavian celebrated in August 29 B.C. for victories in Illyricum, Actium, and Egypt:at Caesar, triplici invectus Romana triumphomoenia, dis Italis votum immortale sacrabat,maxima ter centum totam delubra per urbem.laetitia ludisque viae plausuque fremebant;omnibus in templis matrum chorus, omnibus arae;ante aras terram caesi stravere iuvenci.ipse sedens niveo candentis limine Phoebidona recognoscit populorum aptatque superbispostibus; incedunt victae longo ordine gentes...(8.714-22)One finds here familiar features of any triumphus: the imperator triumphans formally entering the city precinct (714-15), bystanders en route applauding the procession (717), the sacrifice of bulls (719), concluding dedications at a temple (720-22), and the display of captives, placards, and models illustrating the victor's conquests (722-28). But Virgil has also rewritten this triumph to take in a wider sacral and historical context. In verse 719 the general prayers and sacrifices and the prominent role of women suggest a supplicatio, a ritual often associated with but [End Page 410] formally distinct from triumphs.6 While triumphing commanders fulfilled vows which they made on the Capitol before their campaigns, Octavian's triumph is marked by the impressive votum of numerous mighty shrines throughout the city (715-16).7 Caesar's celebration looks ahead as well as backwards; it in effect announces the emergent leader's vast program of building and restoring temples, which was especially prominent in the period immediately after the triumph of 29.8 For Virgil, Caesar's triumphus inaugurates the religious renewal of Rome.By far the most momentous changes to the regular triumph occur in the scene at Apollo's gleaming temple, which in this context must be the new Palatine shrine.9 Whether dona... populorum (721) are the [End Page 411] ceremonial crowns which captives presented to the victor or euphemistically denote battle spoils from various peoples, the act of affixing them to the temple suggests that the triumphator has reached the triumph's end point. So does... (shrink)

ABSTRACTWe investigated the impact of emotions on learning vocabulary in an unfamiliar language to better understand affective influences in foreign language acquisition. Seventy native English speakers learned new vocabulary in either a negative or a neutral emotional state. Participants also completed two sets of working memory tasks to examine the potential mediating role of working memory. Results revealed that participants exposed to negative stimuli exhibited difficulty in retrieving and correctly pairing English words with Indonesian words, as reflected in a lower (...) performance on the prompted recall tests and the free recall measure. Emotional induction did not change working memory scores from pre to post manipulation. This suggests working memory could not explain the reduced vocabulary learning in the negative group. We argue that negative mood can adversely affect language learning by suppressing aspects of native-language processing and impeding form-meaning mapping with second language words. (shrink)

Data monitoring committees often are employed to review interim findings of randomised controlled trials. Interim findings are kept confidential until the data monitoring committee finds that they provide sufficiently compelling evidence regarding efficacy, typically because they have crossed the pre-defined statistical boundaries, or they raise serious concerns about safety. While this practice is vital to maintaining the scientific integrity of controlled trials and thereby ensuring their social value, it has been criticised as unethical. Commentators argue that withholding interim findings from (...) research participants is deceptive, inconsistent with valid informed consent, and a violation of respect for participants’ autonomy. The present article examines these arguments, focusing specifically on confidential data monitoring for efficacy. This practice need not be deceptive provided its use is disclosed to prospective research participants. In addition, confidential data monitoring does not make research participants worse off than they would be in the clinical setting and represents an acceptable limitation on the options available to prospective research participants. Taken together, these considerations suggest confidential data monitoring, subject to adequate safeguards, is ethically acceptable. (shrink)

The practice of transplantation of vital organs from “brain-dead” donors is in a state of theoretical disarray. Although the law and prevailing medical ethics treat patients diagnosed as having irreversible total brain failure as dead, scholars have increasingly challenged the established rationale for regarding these patients as dead. To understand the ethical situation that we now face, it is helpful to revisit the writings of the philosopher Hans Jonas, who forcefully challenged the emerging effort to redefine death in the late (...) 1960s.

Emile Benvcniste may be used to introduce the topic. The French linguist begins an essay on “Euphemisms Ancient and Modern” with a paradox about the early Greek definitions of euphemism. “To speak words which augur well” is one meaning given, but another is “to maintain silence”. This initial contradiction is further compounded by yet a third expression, “to shout in triumph”. The dilemma is. however, easily dissolved. To speak words which augur well implies, for special occasions, an exhortation even to (...) shout triumphantly, “to assent by an, auspicious outcry”: it further implies, again depending on the circumstances, “to avoid words which augur ill”, hence, if necessary, to say nothing. As one definition explains “avoid all unlucky words during sacred rites: hence, as the surest mode of avoiding them, keep a religious silence” (original emphasis). Paradox terminates; we are merely dealing with “a euphemism for a euphemism” taking an expression of Benveniste out of context. (shrink)

Participants are often not informed by investigators who conduct randomised, placebo-controlled acupuncture trials that they may receive a sham acupuncture intervention. Instead, they are told that one or more forms of acupuncture are being compared in the study. This deceptive disclosure practice lacks a compelling methodological rationale and violates the ethical requirement to obtain informed consent. Participants in placebo-controlled acupuncture trials should be provided an accurate disclosure regarding the use of sham acupuncture, consistent with the practice of placebo-controlled drug trials.
