MORAL REFORM,MORAL DISAGREEMENT,AND ABORTION

Abstract: Bernard Gert argues that legitimate moral disagreement calls for tolerance and moral humility; when there is more than one morally acceptable course of action, then intolerance and what Gert calls “moral arrogance” would be objectionable. This article identifies some possible difficulties in distinguishing moral arrogance from moral reform and then examines Gert's treatment of abortion as a contemporary example of moral disagreement that he characterizes as irresolvable.     

Brief report: preliminary results of a suicide awareness mass media campaign in Cuyahoga County, Ohio

Little information is currently available concerning the effects of suicide awareness and prevention campaigns. This brief report provides preliminary information about the influence of such a media campaign on the number of suicide-related telephone calls to an emergency mental health service in Cuyahoga County, Ohio. Examination of the pattern of calls before, during, and between phases of the campaign suggests that the media campaign significantly increased telephone calls to the emergency service. We provide this information to catalyze similar sharing of data and experiences among those organizations and agencies working to prevent suicide.     

Panpsychism,Emergentism and the Metaphysics of Causation

This article uses causation to show that panpsychism and emergentism share far less than most philosophers suppose. It argues that panpsychism has features, among them its rationalism, that force what the article calls a strong account of causation. And that emergentism entails what the article calls a weak account of causation incompatible with any strong account. The article then ventures that panpsychism and emergentism form parts of two wide‐ranging but incompatible metaphysical packages.     

Close Calls and the Confident Agent: Free Will, Deliberation, and Alternative Possibilities

Two intuitions lie at the heart of our conception of free will. One intuition locates free will in our ability to deliberate effectively and control our actions accordingly: the ‘Deliberation and Control’ (DC) condition. The other intuition is that free will requires the existence of alternative possibilities for choice: the AP condition. These intuitions seem to conflict when, for instance, we deliberate well to decide what to do, and we do not want it to be possible to act in some other way. I suggest that intuitions about the AP condition arise when we face ‘close calls,’ situations in which, after deliberating, we still do not know what we really want to do. Indeed, several incompatibilists suggest such close calls are necessary for free will. I challenge this suggestion by describing a ‘confident agent’ who, after deliberating, always feels confident about what to do (and can then control her actions accordingly). Because she maximally satisfies the DC condition, she does not face close calls, and the intuition that the AP condition is essential for free will does not seem to apply to her. I conclude that intuitions about the importance of the AP condition rest on our experiences of close calls and arise precisely to the extent that our deliberations fail to arrive at a clear decision. I then raise and respond to several objections to this thought experiment and its relevance to the free will debate.     

Factors influencing self‐report of mobile phone use: the role of response prompt,time reference and mobile phone use in recall

The current study (n = 180) assesses factors affecting the recall of past mobile phone behaviour. It manipulates two factors hypothesised as influencing recall of duration and number of calls made: time reference (24 hours vs. 3 days) and context prompt (temporal, person called, reason for call) and also considers their impact in relation to levels of mobile phone use. A measure of recall error was constructed by matching self‐reported calls to actual calls and weighting for actual usage. The results indicate that most people tend to overestimate duration and underestimate number of phone calls, although these discrepancies are related to actual amount of mobile phone use. The manipulations of time reference and context prompt have some effect on the patterns of recall in relation to number, rather than duration, of calls. The implications of these results for the development of reliable and valid self‐report measures of mobile phone use are discussed. Copyright © 2008 John Wiley & Sons, Ltd.

Caller characteristics, call contents, and types of assistance provided by caller sex and age group in a Canadian Inuit crisis line in Nunavut, 1991-2001

Analysis of calls made to a northern Canadian Inuit crisis line in the territory of Nunavut between 1991 and 2001 revealed that the majority of users were adult females who called to discuss problems primarily related to relationships and loneliness/boredom. Younger callers tended to make prank calls. The volunteer staff used mostly empathetic listening and suggestions. Referral recommendations made were primarily to social services. Although some callers experienced a language barrier, others found the service to be helpful. Results suggest that the crisis line was underused by young Inuit males who represent a group that are most in need of crisis intervention.     

Temporal Fluctuations in Suicide Calls to a Crisis Intervention Service

Suicide-related calls received by a crisis intervention center were analyzed for temporal variations. The overall number of calls, calls concerning personal suicidal ideation, and calls concerning third-person suicide potential varied by both month and day of the week. Ideation calls and calls involving a suicide attempt varied by day of the month. Month and day of the week variation in third-person calls paralleled variations in completed suicides. Fluctuations were large enough to be useful in scheduling crisis center staff. The possibility that third-person calls represent a greater suicide threat than first-person calls is discussed.     

Open-ended categorization of chick-a-dee calls by black-capped chickadees (Poecile atricapilla)

The authors trained black-capped chickadees (Poecile atricapilla) in an operant discrimination with exemplars of black-capped and Carolina chick-a-dee calls, with the goal of determining whether the birds memorized the calls of conspecifics and heterospecifics or classified the calls by species. Black-capped calls served as both rewarded (S+) and unrewarded (S-) stimuli (the within-category discrimination), whereas Carolina chick-a-dee calls served as S-s (the between-category discrimination) in the black-capped chick-a-dee call S+ group. The Carolina call S+ group had Carolina calls as S+s and S-s (within-category) and black-capped calls as S-s (between-category). Both groups discriminated between call categories faster than within a call category. In 2 subsequent experiments, both S+ groups showed transfer to novel calls and propagation back to between-category calls. The results favor the hypothesis that the acoustically similar social calls of the 2 species constitute separate open-ended categories.     

Kane,Luck, and the significance of free will

Abstract

This paper raises a pair of objections to the novel libertarian position advanced in Robert Kane's recent book, The Significance of Free Will.The first objection's target is a central element in Kane's intriguing response to what he calls the “Intelligibility” and “Existence” questions about free will. It is argued that this response is undermined by considerations of luck.The second objection is directed at a portion of Kane's answer to what he calls “The Significance Question” about free will: “Why do we, or should we, want to possess a free will that is incompatible with determinism? Is it a kind of freedom ‘worth wanting’... and, if so, why?” A desire for “objective worth” has a featured role in his answer. However, a compatibilist can have that desire.     

Reciprocal recognition of sifaka (<Emphasis Type="Italic">Propithecus verreauxi verreauxi</Emphasis>) and redfronted lemur (<Emphasis Type="Italic">Eulemur fulvus rufus</Emphasis>) alarm calls

Redfronted lemurs (Eulemur fulvus rufus) and Verreaux's sifakas (Propithecus verreauxi verreauxi) occur sympatrically in western Madagascar. Both species exhibit a so-called mixed alarm call system with functionally referential alarm calls for raptors and general alarm calls for carnivores and raptors. General alarm calls also occur in other contexts associated with high arousal, such as inter-group encounters. Field playback experiments were conducted to investigate whether interspecific recognition of alarm calls occurs in both species, even though the two species rarely interact. In a crossed design, redfronted lemur and sifaka alarm calls were broadcast to individuals of both species, using the alarm call of chacma baboons (Papio cynocephalus) as a control. Both species responded with appropriate escape strategies and alarm calls after playbacks of heterospecific aerial alarm calls. Similarly, they reacted appropriately to playbacks of heterospecific general alarm calls. Playbacks of baboon alarm calls elicited no specific responses in either lemur species, indicating that an understanding of interspecific alarm calls caused the responses and not alarm calls in general. Thus, the two lemur species have an understanding of each other's aerial as well as general alarm calls, suggesting that even in species that do not form mutualistic associations and rarely interact, common predator pressure has been sufficient for the development of heterospecific call recognition.     

Prairie dog alarm calls encode labels about predator colors

Some animals have the cognitive capacity to differentiate between different species of predators and generate different alarm calls in response. However, the presence of any addition information that might be encoded into alarm calls has been largely unexplored. In the present study, three similar-sized human females walked through a Gunnison’s prairie dog (Cynomys gunnisoni) colony wearing each of three different-colored shirts: blue, green, and yellow. We recorded the alarm calls and used discriminant function analysis to assess whether the calls for the different-colored shirts were significantly different. The results showed that the alarm calls for the blue and the yellow shirts were significantly different, but the green shirt calls were not significantly different from the calls for the yellow shirt. The colors that were detected, with corresponding encoding into alarm calls, reflect the visual perceptual abilities of the prairie dogs. This study suggests that prairie dogs are able to incorporate labels about the individual characteristics of predators into their alarm calls, and that the complexity of information contained in animal alarm calls may be greater than has been previously believed.     

Effect of acoustic cue modifications on evoked vocal response to calls in zebra finches (Taeniopygia guttata)

Besides their song, which is usually a functionally well-defined communication signal with an elaborate acoustic structure, songbirds also produce a variety of shorter vocalizations named calls. While a considerable amount of work has focused on information coding in songs, little is known about how calls' acoustic structure supports communication processes. Because male and female zebra finches use calls during most of their interactions and answer to conspecific calls without visual contact, we aimed at identifying which calls' acoustic cues are necessary to elicit a vocal response. Using synthetic zebra finch calls, we examined evoked vocal response of male and female zebra finches to modified versions of the distance calls. Our results show that the vocal response of zebra finches to female calls requires the full harmonic structure of the call, whereas the frequency downsweep of male calls is necessary to evoke a vocal response. It is likely that both female and male calls require matching a similar frequency bandwidth to trigger a response in conspecific individuals.     

Responses of white-faced capuchins (Cebus capucinus) to naturalistic and experimentally presented food-associated calls

In the context of foraging, many animal species produce specific calls that attract others. Researchers hypothesize that these vocalizations function to inform others about food; however, few studies have investigated whether food-associated calls alone are sufficient to cause individuals to respond as if they have been informed about food. Playback experiments on white-faced capuchins (Cebus capucinus) investigated whether listeners could infer the presence of food merely by hearing food-associated calls. Recipients looked significantly longer toward the call source and approached the speaker more often after hearing food-associated calls, as compared with control calls. Because these responses are not indicative of feeding, it is unclear whether listeners associated the calls with food. Nonetheless, these responses, specific to food-associated calls, may increase individuals' chances of finding food.     

Auditory perception of conspecific and heterospecific vocalizations in birds: evidence for special processes.

Budgerigars (Melopsittacus undulatus), canaries (Serinus canaria), and zebra finches (Poephila guttata castanotis) were tested for their ability to discriminate among distance calls of each species. For comparison, starlings (Sturnus vulgaris) were tested on the same sounds. Response latencies to detect a change in a repeating background of sound were taken as a measure of the perceptual similarity among calls. All 4 species showed clear evidence of 3 perceptual categories corresponding to the calls of the 3 species. Also, budgerigars, canaries, and zebra finches showed an enhanced ability to discriminate among calls of their own species over the calls of the others. Starlings discriminated more efficiently among canary calls than among budgerigar or zebra finch calls. The results show species differences in discrimination of species-specific acoustic communication signals and provide insight into the nature of specialized perceptual processes.     

Functional referents and acoustic similarity revisited: the case of Barbary macaque alarm calls

Barbary macaques (Macaca sylvanus) utter "shrill barks" in response to disturbances in their surroundings. In some cases, the majority of group members react by running away or climbing up a tree. In many other instances, however, group members show no overt reaction to these calls. We conducted a series of playback experiments to identify the factors underlying subjects' responses. We presented calls given in response to dogs that had elicited escape responses and calls that had failed to do so. We also presented calls given in response to snakes and to the observer approaching the sleeping-trees at night. An acoustic analysis of the calls presented in the playback experiments (electronic supplementary material, audioclip S1) revealed significant differences among calls given in response to dogs, the observer approaching at night, and snakes. However, the analysis did not detect any differences between calls given in response to dogs that were related to whether or not they had elicited escape responses in the first place. Correspondingly, after playback of calls given in response to dogs, we observed no difference in subjects' responses in relation to whether or not the calls had initially elicited escape responses. Subjects showed startle or escape responses significantly more often after playbacks of calls given in response to dogs than after calls given in response to observers. Playbacks of calls given in response to snakes failed to elicit specific responses such as standing bipedally or scanning the grass. Although these findings may imply that responses depend on the external referent, they also indicate that there is no clear-cut relationship between the information available to the listeners and their subsequent responses. This insight forces us to extend current approaches to identifying the meaning of animal signals. Accepted after revision: 15 May 2001 Electronic Publication     

Skepticism,naturalism, pyrrhonism

Skepticism and naturalism bear important connections with one another. Do they conflict or are they different sides of the same coin? In this paper, by considering the ways in which Sextus and Hume have examined these issues, I offer a Pyrrhonian response to Penelope Maddy's attempt to reject skepticism within the form of naturalism that she calls “second philosophy” (Maddy, 2007, 2017) and to Timothy Williamson's attempt to avoid skepticism from emerging within his knowledge-first approach (Williamson, 2000). Some lessons about Pyrrhonism result.     

Adolescent Cell Phone Communications with Mothers and Fathers: Content,Patterns, and Preferences

Adolescents participated in qualitative interviews (N?=?40) and permitted researchers to check their cell phone histories (N?=?35) for the content and frequency of text and call communications with parents. Communications focused predominantly on day-to-day “managerial” aspects of parent–child relationships but also facilitated emotional connections between adolescents and parents. Adolescents preferred to use texts to engage in managerial communications and calls to connect emotionally, but logistical constraints resulted in most cell phone communications between adolescents and parents involving calls. Participants communicated more with mothers than fathers, regardless of communication content or medium. This was true regardless of family structure, although gender-of-parent differences were accentuated for adolescents in mother-only households. This pattern was explained by both greater maternal accessibility and adolescent preferences for communication with mothers. Communications with fathers tended to occur either when mothers were not available or when the communication was focused on a highly specific set of stereotypically masculine content areas.     

Moral Shallowness, Metaphysical Megalomania, and Compatibilist-Fatalism

In the debate on free will and moral responsibility, Saul Smilansky is a hard source-incompatibilist who objects to source-compatibilism for being morally shallow. After criticizing John Martin Fischer’s too optimistic response to this objection, this paper dissipates the charge that compatibilist accounts of ultimate origination are morally shallow by appealing to the seriousness of contingency in the framework of, what Paul Russell calls, compatibilist-fatalism. Responding to the objection from moral shallowness thus drives a wedge between optimists and fatalists within the compatibilist camp.     

Causality,emergence, computation and unreasonable expectations

I argue that much of current concern with the role of causality and strong emergence in natural processes is based upon an unreasonable expectation placed on our ability to formalize scientific knowledge. In most disciplines our formalization ability is an expectation rather than a scientific result. This calls for an empirical approach to the study of causation and emergence. Finally, I suggest that for advances in complexity research to occur, attention needs to be paid to understanding what role computation plays in this experimental approach.
