The Network Autocorrelation Model using Two-mode Data: Affiliation Exposure and Potential Bias in the Autocorrelation Parameter

The network autocorrelation model has been a workhorse for modeling network influences on individual behavior. The standard network approaches to mapping social influence using network measures, however, are limited to specifying an influence weight matrix (W) based on a single mode network. Additionally, it has been demonstrated that the estimate of the autocorrelation parameter ρ of the network effect tends to be negatively biased as the density in W matrix increases. The current study introduces a two-mode version of the network autocorrelation model. We then conduct simulations to examine conditions under which bias might exist. We show that the estimate for the affiliation autocorrelation parameter (ρ) tends to be negatively biased as density increases, as in the one-mode case. Inclusion of the diagonal of W, the count of the number of events participated in, as one of the variables in the regression model helps to attenuate such bias, however. We discuss the implications of these results.     

The team as a secure base: Promoting resilience and competence in child and family social work

This paper outlines research findings on the relevance of the Secure Base model (Schofield & Beek, 2014) for developing supportive teams in child and family social work. When the social work team functions as a secure base, this can help workers cope with the emotional demands of the role. The concept of the secure base comes from attachment theory (Bowlby, 1969) in which our relationships with significant others, who are available, sensitive to our needs and reliable, provide us with a secure base to return to when life is stressful and provide us with comforting internal mental models when we are physically away from them. This ‘secure base for exploration’ reduces anxiety and enables us to engage with the world, consider the internal world of others (empathy) and remain resilient when life is stressful. Using data from 52 phone interviews with child and family social workers across eight local authorities in the UK, we show how the Secure Base model has relevance for emotion regulation and resilience for child and family social workers. Data were analysed using Theoretical Thematic Analysis (Braun & Clarke, 2006). In the context of the emotional demands of social work, our data indicate that the supervisors and teams provide a work related secure base across five dimensions by behaving in ways which instil these beliefs: Availability -‘People are there for me’; Sensitivity - ‘My feelings are manageable’; Acceptance - I don't always have to be strong’; Cooperation - ‘I can work with others to find a solution’; Team belonging - ‘I am valued and I belong’. Implications for practice are proposed to help supervisors and team members reflect on beliefs and behaviours which can help provide a secure base for their teams.     

Statistical power of the social network autocorrelation model

The network autocorrelation model has become an increasingly popular tool for conducting social network analysis. More and more researchers, however, have documented evidence of a systematic negative bias in the estimation of the network effect (ρ). In this paper, we take a different approach to the problem by investigating conditions under which, despite the underestimation bias, a network effect can still be detected by the network autocorrelation model. Using simulations, we find that moderately-sized network effects (e.g., ρ = .3) are still often detectable in modest-sized networks (i.e., 40 or more nodes). Analyses reveal that statistical power is primarily a nonlinear function of network effect size (ρ) and network size (N), although both of these factors can interact with network density and network structure to impair power under certain rare conditions. We conclude by discussing implications of these findings and guidelines for users of the autocorrelation model.     

The effect of density on the level of bias in the network autocorrelation model

Researchers interested in the effects of social network ties on behavior are increasingly turning to the network autocorrelation model, which allows for the simultaneous computation of individual-level and network-level effects. Earlier research, however, had pointed to the possibility that the maximum likelihood estimates used to compute the network autocorrelation model yielded negatively biased parameter estimates. In this paper we use simulations to examine whether – and the conditions under which – a negative bias exists. We show that the network parameter estimate ρ is negatively biased under nearly all conditions, and that this bias becomes more severe at higher levels of both ρ and network density. We conclude by discussing the implications of these findings for researchers planning to use the network autocorrelation model.     

Social norms and tax compliance: Framing the decision to pay tax

Observed levels of tax compliance are higher than predicted levels (when predictions are based on Allingham and Sandmo's neoclassical model of tax evasion). They are higher if social norms recognise the importance of compliance. But how do social norms frame decisions to pay tax? Can prospect theory be applied to shed insight into the way that social norms exert their influence? An analysis of questionnaire responses (from Italy and from the UK) suggests that they exert their influence by changing the reference points that individuals use when they code changes as ‘gains’, or ‘losses’. The evidence suggests that social norms frame the decision to pay tax by changing individuals’ perceptions of their entitlement to income. This consideration is important when designing policy to deter evasion.     

Spectral goodness of fit for network models

We introduce a new statistic, ‘spectral goodness of fit’ (SGOF) to measure how well a network model explains the structure of the pattern of ties in an observed network. SGOF provides a measure of fit analogous to the standard R² in linear regression. Additionally, as it takes advantage of the properties of the spectrum of the graph Laplacian, it is suitable for comparing network models of diverse functional forms, including both fitted statistical models and algorithmic generative models of networks. After introducing, defining, and providing guidance for interpreting SGOF, we illustrate the properties of the statistic with a number of examples and comparisons to existing techniques. We show that such a spectral approach to assessing model fit fills gaps left by earlier methods and can be widely applied.     

Comparing child protection decision-making in England and Finland: supervised or supported judgement?

ABSTRACT

Systems for the protection of children have evolved differently across nation states. Studies have identified contrasting system ‘orientations’, related to how child protection problems are framed and how organisations respond in different contexts. In this study, the influence of national and organisational factors on practice-level decision reasoning by social workers has been compared. Interviews were conducted with 30 child protection social workers in sites across England and Finland, structured around two hypothetical case vignettes. While similarities were observed in how the social workers responded to the vignettes, there were differences in the nature and extent of managerial involvement described, with the English social workers appearing to rely on managerial input for decision-making to a greater extent than the Finnish social workers. These findings suggest evidence for two distinct organisational approaches to decision-making: ‘supervised’ and ‘supported’ judgement. Here, supervised judgement describes a hierarchical, ‘top-down’ form of decision-making, while supported judgement describes a more horizontal and shared decision-making approach. The lens of comparative methodology has revealed how these organisational factors come into play in different child protection systems. The practice implications of supervised, manager-led approaches to decision-making, as contrasted with supported, team-led approaches, are discussed.     

Celebrity Philanthropy in China: An Analysis of Social Network Effect on Philanthropic Engagement

Celebrity philanthropy is a recent but widespread phenomenon in China. Using social network analysis, this paper seeks to answer the following questions: Is a celebrity’s position within a social network related to that celebrity’s philanthropic engagement, and how? Does a celebrity’s network position interact with normative influence to affect philanthropic engagement? What implications the study has for the development of modern philanthropy in China? Hypotheses regarding the associations between philanthropic engagement and a celebrity’s social network were tested using a sample from the “Celebrity Relationship Database.” Findings suggest that philanthropic engagement was more common in the center of the social network; under normative influence, a celebrity was more likely to engage in philanthropic activities if other members within the social network were active in philanthropic engagement; and, the effect of normative influence was stronger for celebrities who were positioned at the center of a social network than those who were positioned at the periphery. Implications for the development of modern philanthropy in China are also discussed.

     

Assessing emotional and social health using photographs: An innovative research method for rural studies and its applicability in a care-farming program for youth

A framework for assessing photographs for the emotional and social health of young people (SHAPE) is described and tested, within the context of a rural program. Two independent raters assessed the photographs of participants. To assess inter-rater reliability, Cohen’ K and Kendall’s W were calculated. The two reviewers’ assessments of photographs were in agreement. The assessment of emotional/behavioural display showed 82% agreement. Agreement between reviewers’ judgements of proxemics (W = .866), interaction (W = .722), engagement (W = .932) and overall impression (W = .804) were all significant (p < .005). The method yielded results indicating that participants found gardening immediately engaging but their approach to equines exhibited a change from fascination to confidence during the program. The visual-diary method is a useful and sensitive method for research: where resources are limited; to complement traditional measures; for use with people who lack appropriate verbal communication or literacy skills to complete questionnaires; young children; other underrepresented groups.     

Polanyi’s two transformations revisited: a ‘bottom up’ perspective

ABSTRACT

In The Great Transformation, Karl Polanyi offers a ‘top-down’ analysis of the rise and demise of Europe’s unregulated market system. He assumes that changes in the organization of the international economy provide particular kinds of opportunities for states to act which, in turn, shapes the extent to which social forces will be able to influence state policy. Consequently, his analysis focuses, first, on the international institutions created by the self-regulating market system; then on the ‘liberal state’ which these made possible; and finally on how the system impacts ‘society as a whole’. The account which this analysis produces systematically underplays the social struggles which propelled and emerged from the rise of Europe’s nineteenth century system and which ultimately led to its demise. In revisiting the two periods that are the focus of Polanyi’s analysis, this article assumes that states and interstate systems reflect the interests of powerful social forces. Thus, working from the ‘bottom up’, it focuses on the class interests that produced Europe’s market system, the state and international structures which reflected and supported them, and the social struggles that ultimately brought about the collapse of the system. What this ‘bottom up’ account reveals is the centrality of a ‘double movement’, not of market expansion and a protective countermove on the part of ‘society as a whole’, but of dominant classes monopolizing economic opportunities from global expansion, and a rising ‘red tide’ of disaffected workers. This double movement, it argues, better explains the demise of the system and the changes that ensued from it.     

Weight matrices for social influence analysis: An investigation of measurement errors and their effect on model identification and estimation quality

Weight matrices, such as used in network autocorrelation models, are useful to investigate social influence processes. The objective of this paper is to investigate a key topic that has received relatively little attention in previous research, namely the issues that arise when observational limitations lead to measurement errors in these weight matrices. Measurement errors are investigated from two perspectives: when relevant ties are omitted, and when irrelevant ties are erroneously included as part of the matrix. The paper first shows analytically that these two situations result in biased estimates. Next, a simulation experiment provides evidence of the effect of erroneously coding the weight matrix on model performance and the ability of a network autocorrelation test to identify social influence effects. The results suggest that depending on the level of autocorrelation and the topology attributes of the underlying matrix, there is a window of opportunity to identify and model social influence processes even in situations where the ties in a matrix cannot be accurately observed.     

Social acceleration and the network effect: a defence of social ‘science fiction’ and network determinism

This essay is a response to Judy Wajcman's essay ‘Life in the fast lane? Towards a sociology of technology and time’ (2008: 59–77). In that article Wajcman argued that recent developments in the sociology of temporal change had been marked by a tendency in social theory towards a form of ‘science fiction’– a sociological theorizing, she maintains, that bears no real relation to actual, empirically provable developments in the field and should therefore be viewed as not contributing to ‘a richer analysis of the relationship between technology and time’ (2008: 61). This reply argues that as Wajcman suggests in her essay, there is indeed an ‘urgent need for increased dialogue to connect social theory with detailed empirical studies’ (2008: 59) but that the most fruitful way to proceed would not be through a constraining of ‘science fiction’ social theorizing but, rather, through its expansion – and more, that ‘science fiction’ should take the lead in the process. This essay suggests that the connection between social theory and empirical studies would be strengthened by a wider understanding of the function of knowledge and research in the context of what is termed ‘true originality’ and ‘routine originality’. The former is the domain of social theory and the latter resides within traditional sociological disciplines. It is argued that both need each other to advance our understanding of society, especially in the context of the fast‐changing processes of technological development. The example of ‘technological determinism’ is discussed as illustrative of how ‘routine originality’ can harden into dogma without the application of ‘true originality’ to continually question (sometimes through ideas that may appear to border on ‘science fiction’) comfortable assumptions that may have become ‘routine’ and shorn of their initial ‘originality’.     

The stranger the better: support and solidarity in the 2011 students’ protests in Chile

This paper analyses the legitimation dynamics of the student protests in Chile 2011, explaining how the support of ‘strangers’ strengthened its position and endurance. By analysing interviews with both activists and uninvolved citizens, I describe a steady pattern whereby they express the strength and legitimacy of the movement by assessing the ‘abstraction’ of the link between protesters and their supporters. The more abstract these relations – the stranger supporters are – the most relevant and meaningful is their support. Beyond establishing the worthiness of protesters’ claims, strangers provide protesters with a mandate, fostering the movement’s cohesion and thus affecting its ability to endure through the conflict. While the literature has mostly looked at adherents as only potential (or failed) constituents, I argue that support that remains external plays a crucial role in social movements’ chances of success. This support needs, however, to avoid being framed as insufficient engagement. Further analysis shows that the distinction between protesters and strangers often requires active boundary work, allowing the movement to maximize the benefits of strangers’ support while managing its risks. The relation between these boundaries, the efficiency of different contention tactics and their adaptation is analysed here. The study argues that strangeness can involve very different, even opposed phenomena, which are often confounded, namely ‘otherness’ and ‘abstraction’. Critically drawing upon Simmel, I explain how it is ‘abstraction’ in particular that helps our understanding of the role of strangers in social movements and consider how this distinction could enrich research on the symbolic aspects of contentious politics.     

Epistemic authority and the gender lens

Researching ‘hidden’ forms of social inequality such as gender often poses particular challenges. Not least of these is how to uncover such dimensions of social life whilst preserving the perspectives of research participants, who may not consider such matters relevant to their lives, particularly if other forms of identity or oppression are more prominent for them. Here, I reflect on these issues in the context of researching user involvement in mental health services from a feminist perspective. I show how ‘uncovering’ gender and other forms of social inequality in the field was aided through adopting a wide analytical lens focusing on power, along with reflexivity and openness in discussing my own political analysis and commitments in relation to the study area with the researched. I also describe how I attempted to resolve the epistemological‐ethical issues involved through conceptualising these in terms of ‘situatedness’ and gender salience and adopting a feminist standpoint which emphasised what researchers can, and indeed should, bring to the research enterprise. Related issues of power and empowerment in the research process are discussed.     

The knowledge,skills and qualities needed for social work in a major paediatric teaching hospital

Abstract

The place of aged care in social work has long been ambiguous, if not marginal. Social work (as do other comparable professions) often displays a reluctance to place practice in this field within the core of the profession that embodies aspects of ageism in contemporary society. Working with older people is frequently characterised as ‘mundane’, ‘routine’ and even ‘not “real” social work’. This paper examines the practice implications of the current policy context. Forms of ‘indirect’ practice are identified as central to social work in aged care, and the implications of this for the standing of aged care social work in the wider profession are discussed. It is argued that ‘indirect’ practices are core to the development of the profession and so should be seen as ‘real’ social work. In conclusion, it is suggested that unless social work affirms practice with older people and their families we will fail to be congruent with our own values.     

Calling for accounts: numbers, monsters and membership1

This article questions how accounts are marked. In asking why some accounts ‘pass muster’ and others fail, the analysis brings into focus the extent to which membership work helps hold the social and the technical apart. The analysis contrasts a long insistence on narrative forms of interaction as defining conditions of co‐presence with numerical regimes in which there is an implicit deletion of social contact under fashionable slogans like ‘action at a distance’. Taking numbers to act as ‘bearers of culture’, the paper contests the idea that numerical forms of accountability delete the membership work traditionally associated with narrative forms of account. Attending closely to ‘occasions’ in which it is appropriate for members to deploy numerical accounts rather than verbal accounts, the argument challenges the idea that a face to face negotiation of social order has been superceded by a pervasive use of perfonnance targets. The article begins by exploring how ‘calls to account’ are created by a reporting of adverse budget variatices within organizations. Using an extended example to consider how such ‘gaps’ affect a manager's conduct towards a spouse who is sick, the analysis shows how the use of numbers becomes crucial to sustaining one's affiliation across a range of memberships. As illustrated, the rehabilitation of numerical artefacts into conceptions of the social greatly expands possibilities for interaction beyond that anticipated by the sociological ideal of ‘co‐presence’.     

The systems' approach and social work methods

Many social work courses are now using ‘system theory’, or as I prefer to call it, ‘a systems' approach’, in teaching social work method on a unitary basis. Most social work techers recognise that the systems' approach is not enough on its own and that traditional methods have a place in practice. What is not clear is how these methods relate to the systems' approach.

In this article the relationship between the systems' approach and various methods and theories of intervention is explored in a number of different ways. Firstly, there is an examination of the relationship of various client, target and action systems. Secondly. Lippitt's analysis of the ‘diagnostic orientations’ of change agents is discussed and related to strategies aimed at changing the goals and the power structures of target systems. Then certain counselling and casework methods are considered in relation to Lippitt's analysis, leading on to a brief comment on methods of intervention based on systems' theory. Finally, an educational strategy for presenting this approach is discussed.
