Despite having faced severe criticism in the past, mereological approaches to group ontology, which argue that groups are wholes and that groups members are parts, have recently managed a comeback. Authors such as Katherine Ritchie and Paul Sheehy have applied neo-Aristotelian mereology to groups, and Katherine Hawley has defended mereological approaches against the standard objections in the literature. The present paper develops the mereological approaches to group ontology further and proposes an analysis of group membership as parthood plus further (...) restrictions. While all mereological accounts agree that group members are parts of the group, it has become clear that this analysis is insufficient. I discuss three proposals to develop the mereological analysis of group membership and then put forward a combined solution to the puzzle. According to my proposal, the members of a reading group are agents who are part of the group and have been designated to contribute to the group. (shrink)

Why do we have obligations to the community to which we happen to belong? For communitarians, membership does more than provide the context for asking this question. In fact, the simple fact of membership goes some way towards justifying our obligations. According to the strong version of the communitarian thesis, membership is the fundamental consideration justifying political obligation; but for the weaker version, membership is one consideration among others and at times may be the less weighty (...) one. John Horton's theory of associative obligations can be read as moving back and forth between strong and weak communitarianism. His communitarianism is strong when he rejects value pluralism, arguing that one consideration, membership, is fundamental. However, Horton also advances claims that are compatible with not only the weak version of the communitarian thesis but also value pluralism. They suggest that, if membership is one reason among others to justify obligations, it is not fundamental as it can be defeated by other considerations. (shrink)

In recent years, membership has dropped in traditional voluntary associations such as Rotary Clubs, Jaycees, and bowling leagues. At the same time, concern is rising about the growth of paramilitary and hate groups. Scholars have warned that these trends are undermining civic society by creating a dangerous number of isolated, mistrustful individuals and organized, antisocial renegades. In this provocative book, however, Nancy Rosenblum takes a new, less narrowly political approach to the study of groups. And she reaches more optimistic (...) conclusions about the state of civil society. Rosenblum argues that we should judge associations not only by what they do for civic virtue, but also by what they do for individual members. She shows that groups of all kinds--among them religious groups, corporations, homeowner associations, secret societies, racial and cultural identity groups, prayer groups, and even paramilitary groups--fill deep psychological and moral needs. And she contends that the failure to recognize this has contributed to an alarmist view of their social impact. For example, she argues that, although extremist groups have obvious antisocial aims, they constrain individuals who would be even more dangerous as maladjusted loners. And she examines the rapid growth of small "support groups"--which are usually dismissed as politically irrelevant--and shows that the moral support people find in such places as prayer groups and self-help groups helps to cultivate the social trust some scholars say is disappearing. Rosenblum concludes that, for practical and principled reasons, American democracy should permit expansive freedom of association, illustrating her case with discussion of specific cases in law. Rosenblum recognizes, however, that freedom has a price. She reminds us that some groups have oppressive and even criminal tendencies, and she explores what liberal democracy should do to ensure that individuals also have freedom within associations and freedom to exit. Throughout, Rosenblum writes eloquently and with a powerful moral voice, drawing on law, practical politics, and psychology to produce an original political theory of the moral uses of pluralism. The book adds remarkable depth and subtlety to one of the leading subjects in contemporary social and political debate. (shrink)

Can our cultural membership excuse us from responsibility for certain actions? Ought the Aztec priest be held responsible for murder, for instance, or does the fact that his ritual sacrifice is mandated by his culture excuse him from blame? Our intuitions here are mixed; the more distant, historically and geographically, we are from those whose actions are in question, the more likely we are to forgive them their acts, yet it is difficult to pinpoint why this distance should excuse. (...) Up close, historically or geographically, we tend to be less forgiving: few of us excuse the Taliban for what they did to women and homosexuals; and if there is less of an outcry concerning treatment not all that dissimilar in Saudi Arabia and elsewhere, this is probably only because these actions are less well publicized.

Rosenblum argues that we should judge associations not only by what they do for civic virtue, but also by what they do for individual members.

This paper focuses on the REC and its political context to clarify the process of ethical review. The examples initially considered are taken from a Research Ethics Review editorial to develop the social explanation of the membership and function of a research ethics committee. It is suggested that the management and administration of medical matters are not always best understood solely in medical terms. The conclusion of the paper is that the larger political relationships determine the membership and (...) function of the research ethics committee. The REC is defined as the political mechanism for formally socializing medical research and its lay members as similarly socializing the REC. (shrink)

This paper considers Kamp and Partee's account of graded membership within a conceptual spaces framework and puts the account to the test in the domain of colors. Three experiments are reported that are meant to determine, on the one hand, the regions in color space where the typical instances of blue and green are located and, on the other hand, the degrees of blueness/greenness of various shades in the blue–green region as judged by human observers. From the locations of (...) the typical blue and typical green regions in conjunction with Kamp and Partee's account follow degrees of blueness/greenness for the color shades we are interested in. These predicted degrees are compared with the judged degrees, as obtained in the experiments. The results of the comparison support the account of graded membership at issue. (shrink)

Infamously, Rawls assumed a democratic society to be “a complete and closed social system,” in that “entry into it is only by birth and exit from it is only by death.” Since the beginning of the present millennium, however, debates about the ethical issues related to immigration have been prominent. In this context, these methodological departure points seem long outdated, if not simply biased. This paper will rework Rawls’s theory of migration for application to the case of provisional immigrants by (...) reworking its theoretical underpinnings. I will argue that once his assumptions are adjusted, Rawlsian notions of ‘stability’ in conjunction with his idea of a ‘society understood as a fair system of cooperation’ justify inclusive membership regimes. In other words, Rawlsian domestic justice requires inclusive membership regimes for provisional immigrants. (shrink)

A decade after the fall of Communism in Europe, the Czech Republic'smembership in the European Union is still a matter of a relatively shortwaiting period of 4 years.

It is increasingly acknowledged that animals have an intrinsic moral status, in part due to the influential work of many moral philosophers. However, surprisingly little has been written by philosophers on whether animals are owed social membership and the rights that attach to membership in society. In this paper, I explore why the idea of social membership matters, particularly in relation to domesticated animals, and how it can guide legal and political reforms. Focusing on social membership (...) identifies neglected avenues for transformative change, and offers new ways of challenging the deeply-embedded ‘human use typologies' that currently govern our relations to domesticated animals. It also raises fascinating philosophical questions about the definition of ‘society' and the role of an ethics of membership. Ultimately, we will need to develop a new philosophy of interspecies society. (shrink)

This study, based on three years of research and over 40 hours of videotaped interaction in psychiatry, investigates the issue of insanity ascription/exoneration in psychiatric interviews. Following Sacks's model of membership categorization analysis, this article analyzes the discursive resources that psychiatrists may draw on to achieve some conclusion regarding their patients' psychopathological status. As it turns out, psychiatrists' invocation of patients' putative membership categories plays a crucial role in the achievement of such a conclusion. I examine some fragments (...) of psychiatric intake interviews and subsequent psychiatric interviews. The analysis shows that the process that may lead to insanity ascription/exoneration in psychiatric interviews basically involves the use of mundane, commonsense reasoning. (shrink)

In the literature on refugeehood in political theory, there has been a recent turn towards what have been called “state system legitimacy” views. These views derive an account of states’ obligations to refugees from a broader picture of the conditions for international legitimacy. This paper seeks to develop the state system legitimacy view of refugeehood by subjecting the most developed version of it—the account developed by David Owen—to critical scrutiny. We diagnose an ambiguity in Owen’s theory of refugeehood, in the (...) concept of political membership, and unpack the implications of this ambiguity for state system legitimacy views. First, we reconstruct the key aspects of Owen’s account of refugeehood and show how it represents an advance over competing theories. Then we discuss the methodological underpinnings of Owen’s account, showing the constraints and opportunities faced by state system legitimacy views. Next, we raise some problems for the conceptual distinctions that Owen develops between different types of refugee protection: asylum, sanctuary, and refuge. The underlying feature that leads to these problems is an ambiguity in the concept of political membership, which is at the core of Owen’s view of refugeehood. Finally, we distinguish two interpretations of political membership in the institution of refugeehood and chart out some possible ways forward for state system legitimacy views. The critique developed here is a sympathetic one, aimed at the further development of state system legitimacy views. (shrink)

Background Diversity in Institutional Review Board (IRB) membership is important for both intrinsic and instrumental reasons, including fairness, promoting trust, improving decision quality, and responding to systemic racism. Yet U.S. IRBs remain racially and ethnically homogeneous, even as gender diversity has improved. Little is known about IRB chairpersons’ perspectives on membership diversity and barriers to increasing it, as well as current institutional efforts to promote diversity, equity, and inclusion (DEI) within IRB membership.Methods We surveyed IRB chairpersons leading (...) U.S. boards registered with the Office for Human Research Protections. Here, we focus exclusively on responses from a subset of 388 chairpersons of IRBs at universities and academic medical centers (AMCs).Results Board chairs were predominantly white and evenly split between men and women. Only about half reported that their boards had at least one member who is Black or African American (51%), Asian (56%), or Hispanic (48%), with 85% of university/AMC boards comprised entirely (15%) or mostly (70%) of white members. Most IRB chairpersons (64%) reported satisfaction with the current diversity of their membership. Participants largely agreed that considering diversity in the selection of IRB members is important (91%), including to improve the quality of IRB deliberation (80%), with an emphasis on racial/ethnic (85%) and gender diversity (74%). Most participants (80%) reported some type of active DEI effort regarding board membership at their university/AMC and just over half (57%) expressed satisfaction with these efforts.Conclusions Our national survey found that although university/AMC IRB chairpersons report valuing diversity in board membership, it may be lacking in key areas. Going forward, it will be important to specify clear reasons for diversity in the IRB context, as well to establish targets for acceptable levels of board diversity and to match DEI efforts to those targets.

Central to the social membership model of animal rights is the claim that relations with nonhuman animals should be reorganized such that domesticated animals are recognized as members of our shared societies. Though some elements of the membership model remain contested, the core of the membership model is that domesticated animals have a claim on, and a direct entitlement to, the benefits of cooperative relations. For many political theorists, however, distributive justice considerations apply only to a certain (...) kind of cooperative relationship. The community of justice recipients is thought to be limited by what Brian Berkey calls the Contribution/Capacity Basis of Entitlement. Accordingly, justice considerations apply to a scheme of cooperation and a conception of justice “entail[s] direct entitlements only for those who are contributors, or, alternatively, those who at least possess the capacities that are necessary to be capable of contributing to such a scheme”. This thesis – referred to as ‘contributionism’ – has typically been utilized to exclude nonhuman animals from justice considerations. The paper argues that contributionism is not fundamentally at odds with justice for domesticated animals, and conversely that contributionism remains a useful conceptual tool for explaining resource sharing with these nonhuman animals.

This paper addresses theoretical problems arising from the vagueness of language terms, and intuitions of the vagueness of the concepts to which they refer. It is argued that the central intuitions of prototype theory are sufficient to account for both typicality phenomena and psychological intuitions about degrees of membership in vaguely defined classes. The first section explains the importance of the relation between degrees of membership and typicality (or goodness of example) in conceptual categorization. The second and third (...) section address arguments advanced by Osherson and Smith (1997), and Kamp and Partee (1995), that the two notions of degree of membership and typicality must relate to fundamentally different aspects of conceptual representations. A version of prototype theory—the Threshold Model—is proposed to counter these arguments and three possible solutions to the problems of logical selfcontradiction and tautology for vague categorizations are outlined. In the final section graded membership is related to the social construction of conceptual boundaries maintained through language use. (shrink)

Organizational membership seems to be linked to a more participatory and informed political culture, to foster electoral participation, and to promote positive feelings toward democracy. More recently, the social capital and associative democracy debates have introduced new arguments about the positive effects of associational involvement. However, little attention has been paid to the problems of measuring associational involvement and to their consequences for our theories. This article discusses the various problems of validity and reliability of our measurements of associational (...) membership. It is shown that different questionnaire formats produce substantially different results. The article also addresses the issue of measurement errors and emphasizes the problems they introduce when doing cross-national comparisons. (shrink)

The recent resurgence of Sacks’ work on membership categorization has highlighted the growing analytic interest in how members’ social category orientations operate at multiple levels of interactional work. One of the outcomes of this, highlighted in Stokoe’s discussion, is the re-emergence of the question of whether membership categorization analysis has been, is, or can be an approach in its own right. In this brief discussion I consider the emergence of ‘MCA’ as an approach to the study of social-knowledge-in-action, (...) the relationship between MCA and contemporary directions in conversation analysis, and finally the future of MCA as it continues to develop.

Political membership refers to the condition of being a member of a particular political community. It is a relational concept by virtue of the fact that it presupposes a political relation shared by several individuals. Thus, a simple way to think about political membership is in terms of the rights and duties common to all full members of a specific community that it enforces. Those privileges and obligations are commonly delimited by political boundaries which regulate the relations among (...) members and aliens.

The world’s elderly population is growing, and in Chile they represent 16.2% of the total population. In Chile, old age is marked by retirement, with a dramatic decrease in income that brings precariousness. Older adults are economically, socially, and psychologically vulnerable populations. This condition increases their likelihood of disengaging from their usual social environment, facilitating their isolation, sadness, and discomfort. From the perspective of social identity, well-being can be explained by two principles: social groups’ importance for health and people’s psychological (...) identification with those groups. This study analyzes the relationships between belonging to the neighborhood and extra-neighborhood groups and neighborhood social identification with WB. Urban or rural location and gender are measured, and the sample is 1,475 older Chilean adults of both sexes. The results show that the majority are not members of social groups, and the remaining 48% are members of one or two groups or organizations. Only 4.47% belong to three groups or organizations. Those who belong to groups obtain higher scores, emotional–mental WB, and positive emotions than older adults who do not belong to any organization. Urban and rural older adults have the same level of WB. Membership in close social organizations or distant ones causes different WB associations. Membership in neighborhood councils reduces gender differences in self-assessment of health. This result supports the idea that participation in heterogeneous groups with a shared sense of belonging to the neighborhood is associated with higher WB and lower perceived loneliness. Social identification with the neighborhood, rather than belonging to the group, had the most widespread impact on WB and health indicators. The variable social identification with the neighborhood was consistently associated with indicators of hedonic WB. (shrink)

This article has four aims. First, it will consider explicitly, and polemically, the hierarchical relationship between conversation analysis and membership categorization analysis. Whilst the CA ‘juggernaut’ flourishes, the MCA ‘milk float’ is in danger of being run off the road. For MCA to survive either as a separate discipline, or within CA as a focus equivalent to other ‘generic orders of conversation’, I suggest it must generate new types of systematic studies and reveal fundamental categorial practices. With such a (...) goal in mind, the second aim of the article is to provide a set of clear analytic steps and procedures for conducting MCA, which are grounded in basic categorial and sequential concerns. Third, the article aims to demonstrate how order can be found in the intuitively ‘messy’ discourse phenomenon of membership categories, and how to approach their analysis systematically as a robust feature of particular action-oriented environments. Through the exemplar analyses, the final aim of the article is to promote MCA as a method for interrogating culture, reality and society, without recourse to its reputed ‘wild and promiscuous’ analytic approach.

During the course of this article, we examine the use of membership categorisation practices by a high-profile celebrity public social media account that has been understood to generate interest, attention and controversy across the UK media ecology. We utilise a data set of harvested tweets gathered from a high-profile public ‘celebrity antagonist’ in order to systematically identify types of antagonistic formulation that have generated different levels of interest within the social media community and beyond. Drawing from classic ethnomethodological studies (...) of banner headlines and other means of generating public interest and ‘making sense’, we respecify high-profile antagonistic tweets as category formulations that exhibit particular and regular membership category features that are reflexively bound to potential antagonistic readings, interest and controversy. In conclusion, we consider how such formulations may be understood to represent resources that constitute ignition points within antagonistic flows of communication and information that can be metaphorically understood as ‘digital wildfires’.

We show unintended consequences of quota regulations to get women on boards. Board members may have different characteristics, and even among women, there are variations. We assume that the characteristics of the board members have an influence on their contributions to boards, to businesses as well as to society. In this paper, we argue that different types of societal pressure to get women on boards have an influence on the social capital characteristics of the women getting multiple board memberships. The (...) paper is drawing on institutional theory and social capital theory, and we distinguish between mimetic, normative, and coercive types of pressure. Through a cluster analysis of 58 Italian “golden skirts”, we show that different types of societal pressure may lead to differences in social capital characteristics. The study has implications for the ongoing international debate about women and diversity on boards, and we propose developing a pressure theory for getting women on boards. (shrink)

In this study caring is shown to be a membershipbound activity to kin and gender categories with strong moral connotations. Being a daughter or being a son are good enough reasons for becoming a caregiver, more so for women than for men. Caregivers were interviewed within the research project The role of women in family care of disabled elderly conducted by the Social and Economic Research Department of INRCA, Ancona, Italy. Transcripts of the interviews were analyzed through a detailed discourse (...) analysis within an ethnomethodological framework. Interview data are treated as interactional encounters that occasion members to display relevant aspects of their identities and morally adequate images of being a caregiver. In the interview interaction, interlocutors display an orientation towards the production of a moral order in which duty and responsibilities are allocated on the basis of gender distinction. Males are generally described as not being responsible for caring tasks, except for situations in which females are absent or sick, that is, for serious reasons. Caregivers'' perception of time dedicated to caring is pervasive. Most caregivers said it occupied all their time, but gender differences were noticeable. Caring tasks are recognized as gender specific practices, thus failing to carry out these tasks is morally sanctionable when women are involved, but not so for men. Many caregivers described caring for older relatives as an intense source of stress, involving serious physical and psychological problems. The study on moral and identity issues related to caregiving highlights endangering constructions of caring. (shrink)

As Professor Dov Fox points out in his essay, reference to “potential life” in American abortion jurisprudence is both indeterminate and underspecified. This commentary highlights that use of the phrase “potential life” by courts also obscures the fact that a position has been taken that biological life is not the equivalent of legal personhood. Worse, the position has been imposed on those who do not share it without offering reasons to justify its imposition in terms that those who oppose it (...) can reasonably be expected to endorse.

This article revisits long-standing questions about consent, membership and emigration in Locke’s thought. Commentators such as A John Simmons have argued that Locke opens political membership to both express consenters and some kind of tacit consenters, and not just to the former, as some have suggested. Simmons’s reading seems to render Locke more sensible in that it does not exclude large numbers of people from membership or burden the few members with all the civic duties, and also (...) in that it allows at least tacit-consenting members the right to relocate, while this right is denied to express-consenting members. Against this reading, the article shows, by resolving seemingly conflicting claims in the text, that people become members only by express consent. It also responds to the criticism that the express-consent-only reading would limit membership to a few and so would render Locke’s account implausible from a practical point of view. The article then addresses the purported restriction Locke imposes on express consenters’ right to emigrate, arguing that the restriction concerns the change of membership and not the right to relocate.

This article shows how journalists deploy membership categorization in managing conversational drama among ordinary individuals in live television discussion. The scripted agenda for the discussion is analyzed as an interactional project, being prosecuted by the hosting journalists. The case in focus is a Finnish discussion program broadcast six days after the 9/11 terrorist attacks in the USA in 2001. Five guests are invited to the studio and introduced to the audience. The membership categories that are activated at the (...) beginning of each entrance are consequential to the way the interactional activities unfold in the rest of the discussion, leading from experiential entitlement to accountability and accusation. Introductory identifications are utilized in the question formulation to push moral accounts from the category members and to build an institutionally proper identity for the journalists. The collaboration in realizing the moral casting vividly illustrates the cultural power of the categorization device in action. (shrink)

This qualitative study examines the relevance of self-determination theory to explain retention and attrition in community supported agriculture (CSA). Using a focus group study of CSA members, we examined whether belonging to a CSA supports basic psychological needs for autonomy, competency and relatedness. We found that it did for continuing members. However, for those who did not renew, membership reduced their sense of autonomy, competency, and relatedness. For continuing members, the intensity of their involvement did not affect their needs (...) satisfaction, though it did influence how those needs were met. Continuing CSA members were also intrinsically motivated and internalized extrinsic motivations. (shrink)

Mark Rowlands gives a compelling argument that, if John Rawls's contractarianism is consistently applied, and Rawls's premises fully explained, then we have powerful reasons to believe that representatives behind the Veil of Ignorance should be blind to species membership in the same way that they are blind to economic status and natural talent.1I argue that even if we suppose this to be correct, these agents would not choose the two principles of justice, but instead ones that more closely resemble (...) utilitarian principles.

In this paper, we demonstrate how the collaborative and sequential unfolding of a story ties into the constitution of a membership categorization device which we have glossed as ‘us and them’. The data come from a focus group activity where first and second generation immigrants to Denmark have been asked to discuss their situation in Denmark. Using Ethnomethodological Conversation and Membership Categorization Analysis, we present one story which involves a story-teller and his family and an elderly Danish couple (...) living in the same block of flats. In the telling of the story, co-participants align and affiliate, and disalign and disaffiliate, at sequentially relevant junctions. We will argue that not only do such phenomena indicate listenership and possible agreement to the moral of the story in its telling, but also to the morally implicative categorical work involved in the story’s telling.

Group interaction is an essential way of social interaction and plays an important role in our social development. It has been found that when individuals participate in group interactions, the group identity of the interaction partner affects the mental processing and behavioral decision-making of subjects. However, little is known about how deaf college students, who are labeled distinctly different from normal hearing college students, will react when facing proposers from different groups in the ultimatum game and its time course. In (...) this study, we recruited 29 deaf college students who played the UG in which they received extremely unfair, moderately unfair, or fair offers from either outgroup members or ingroup members, while their brain potentials were recorded. The behavioral results showed that group membership did not impact the acceptance rate of deaf college students. But, event-related potential analysis demonstrated an enhanced feedback-related negativity elicited by ingroup members compared to outgroup members. Importantly, we found that under fairness conditions, deaf college students induced more positive P2 and P3 facing ingroup members compared to outgroup members. Our results demonstrated that group membership may modulate the performance of deaf college students in the UG and the existence of ingroup bias among deaf college students. This provides some evidence for the fairness characteristics of special populations, so that to improve the educational integration of colleges and universities. (shrink)

The problem is addressed of establishing the satisfiability of prenex formulas involving a single universal quantifier, in diversified axiomatic set theories. A rather general decision method for solving this problem is illustrated through the treatment of membership theories of increasing strength, ending with a subtheory of Zermelo-Fraenkel which is already complete with respect to the ∀*∀ class of sentences. NP-hardness and NP-completeness results concerning the problems under study are achieved and a technique for restricting the universal quantifier is presented.

It has been repeatedly stated that approach and avoidance reactions to emotional faces are triggered by the intention signalled by the emotion. This line of thought suggests that each emotion signals a specific intention triggering a specific behavioural reaction. However, empirical results examining this assumption are inconsistent, suggesting that it might be too short-sighted. We hypothesise that the same emotional expression can signal different social messages and, therefore, trigger different reactions; which social message is signalled by an emotional expression should (...) be influenced by moderating variables, such as the group membership of the expresser. In two experiments, we show that group membership influences approach and avoidance reactions to emotional expressions: Emotions (fear and happiness) expressed by in-group members elicited concordant behaviour, whereas emotions expressed by out-group members activated the reverse pattern. A third experiment, in which participants directly evaluated smiling and fearful individuals resembling in-group and out-group members supported this result. (shrink)

Does one have special obligations to support the political institutions of one’s own country precisely because it is one’s own? In short, does one have political obligations? This book argues for an affirmative answer, construing one’s country as a political society of which one is a member, and a political society as a special type of social group. The obligations in question are not moral requirements derived from general moral principles. They come, rather, from one’s participation in a special kind (...) of commitment: a joint commitment. This theory is referred to as the plural subject theory of political obligation since, by the author’s definition, those who are party to any joint commitment constitute a plural subject of some action in a broad sense of the term. Several alternative theories are compared and contrasted with plural subject theory, with a particular focus on the most famous — actual contract theory — according to which membership in a political society is a matter of participation in an agreement. The book offers plural subject accounts of both social rules and everyday agreements, and includes discussion of political authority and punishment. (shrink)

Johann Gottlieb Fichte argues that one semantic presupposition of claims about our entitlements is the idea that others are capable of autonomy. Individuals cannot demand anything from others, even submission, unless they also presuppose—although perhaps without acknowledging this to themselves—that others are free agents. Thus, the autonomy of others is a pre-condition of our exercise of autonomy. Why do individuals and groups often try to justify their own entitlement to rights at the expense of the freedom of others, thereby simultaneously (...) assuming and denying their freedom? This paper investigates what constitution of group agency gives individual members of the group the best chance to develop and sustain a moral character consistent with the ideal of equal autonomy. I argue that liberalism fosters the sort of group agency that improves individuals’ chances to acquire epistemically reliable beliefs about the moral status of others. I apply my findings to the discussion of court decisions in Gaines, Brown, and the race nuisance cases. (shrink)
