You can’t teach understanding, you construct it: Applying social network analysis to organizational learning

Researchers in the fields of learning and social network theory have emphasized the importance of social relationships for acquiring information. However, little inquiry has been made into the influence that the structure of social relationships within an organization has on enhancing learning capability. Organizational learning and social network theory and methods are employed to develop a conceptual framework that links network structural attributes with learning characteristics in order to identify potential barriers to organizational learning. The results from case studies support the proposition that specific social network structures are associated with different barriers to organizational learning.

Airline alliances

PurposeThe purpose of this paper is to present global airline alliances from a complementary and original angle to the existing works: “specific social networks”. “Social” as it is an inter‐organisational network through business relations between airline companies and “specific” as these are formal relations of contractual types (joint marketing, code sharing agreements, etc.).Design/methodology/approachIt is an empirical study, about cooperation agreements between global regular airlines, over a time period of six years from Airline Business Review database. The graph theory is used to measure social network and graphics representation for illustrations.FindingsThe results show that there is a real process of social embeddedness correlated to the airline alliances members' experiences. Their structuring as networks varies in time following a life cycle and their specific morphologies affect their performance.Practical implicationsThe paper proposes numerous measures to approach the structure of airline alliances and graphics representations to illustrate networks.Originality/valueThe paper draws a synthesis from the morphology and morphogenesis of airline alliances, proposing thereby some of their structural properties which have an impact on their competitiveness.

The assessment of positivity and negativity in social networks: the reliability and validity of the social relationships index

AbstractThe Social Relationships Index (SRI) was designed to examine positivity and negativity in social relationships. Unique features of this scale include its brevity and the ability to examine relationship positivity and negativity at the level of the specific individual and social network. The SRI's psychometric properties were examined in three studies. The SRI demonstrated good psychometric properties, including test–retest reliability for the assessment of positivity and negativity, and of relationship classifications across social networks. Additionally, discriminant and convergent validity was established with existing social relationship and personality scales. Finally, the SRI showed some generalizability across different contexts. These studies suggest that the SRI is a reliable and valid alternative measure for use in health studies that require a shorter assessment of relationships. © 2009 Wiley Periodicals, Inc.

Community dynamics generates complex epidemiology through self-induced amplification and suppression

AbstractThe development of quantitative models of outbreaks is key to their eventual control, from human and computer viruses through to social (and antisocial) activities. Standard epidemiological models can reproduce many general features of outbreaks. Unfortunately, the large temporal fluctuations which often dominate real-world data are thought to require more complicated, system-specific models involving super-spreaders, specific social network topologies and rewirings, and birth-death processes. However we show here that these large fluctuations have a generic explanation in terms of underlying community dynamics. Communities increasing (or decreasing) in size, act as instantaneous amplifiers (or suppressors) yielding a complex temporal evolution whose features vary dramatically according to the relative timescales of the community dynamics. We uncover, and provide an analytic theory for, a novel epidemiological phase transition driven by the population's response to an outbreak. An imminent epidemic will be suppressed if individual communities start to break up more frequently or join together less frequently, but will be amplified if the reverse is true.

Relationships Between Personal, Depression and Social Network Factors and Sleep Quality in Community-Dwelling Older Adults

Improving sleep quality is key to increasing life quality for the elderly. Clarifying the nature of sleep conditions and the factors that influence such is necessary to enrich the base of knowledge available to the clinical nursing profession and encourage effective nursing interventions in older populations. Purposes of this study were to describe sleep quality and identify the personal, depression and social network determinants of sleep quality among older people living independently. A cross-sectional research design was used, and 187 persons 65 years of age or older were recruited using two-stage random sampling from communities in Taipei City, Taiwan. All subjects were informed by the researchers and were asked to provide personal (demographic data, lifestyle behavior), depression, social network (perceived the relationships with and support from family, relatives/friends), and sleep quality (Chinese version of the Pittsburgh Sleep Quality Index, C-PSQI) information. Findings revealed that 25.7% of subjects were "poor sleepers" (attaining C-PSQI global scores > 5). The study identified significant relationships between three personal variables (alcohol consumption, educational level, and depressive tendencies), one social variable (relationships with relatives/friends) and sleep quality. Depression tendency, relationships with relatives/friends, college and above educational level, and habitual alcohol consumption accounted for 46.1% of sleep quality variance. Findings enrich the knowledge base by highlighting specific personal, depression and social network factors that could help nurses to assess sleep conditions more comprehensively. Nurses caring for older people should consider depression and social network factors (particularly the relationships with relatives/friends may play a discriminating role) as important determinants of sleep quality.

Sex workers, fem queens, and cross-dressers: Differential marginalizations and HIV vulnerabilities among three ethnocultural male-to-female transgender communities in New York City

This article describes 3 distinct ethnocultural male-to-female transgender communities in New York City: the low-income African American/Black and Latina(o) House Ball community; low-income, often undocumented immigrant Asian sex workers; and middle-class White cross-dressers. These communities are highly socially isolated from each other and are more connected to their ethnocultural contexts than to an abstract and shared transgender identity. Whereas previous research either has viewed male-to-female transgender people as one monolithic group or has separated them into abstract racial categories unconnected to their communities and lifestyles, this article positions them within specific social networks, cultures, neighborhoods, and lifestyles. With regard to HIV vulnerabilities, violence, and rape, House Ball community members seemed to engage in the riskiest form of survival sex work, whereas Asian sex workers seemed to engage in moderate-risk survival sex work. White cross-dressers seemed to engage in very low-risk recreational sex work.

Do social networks affect the use of residential aged care among older Australians?

BackgroundOlder people's social networks with family and friends can affect residential aged care use. It remains unclear if there are differences in the effects of specific (with children, other relatives, friends and confidants) and total social networks upon use of low-level residential care and nursing homes.MethodsData were drawn from the Australian Longitudinal Study of Ageing. Six waves of data from 1477 people aged ≥ 70 collected over nine years of follow-up were used. Multinomial logistic regressions of the effects of specific and total social networks on residential care use were carried out. Propensity scores were used in the analyses to adjust for differences in participant's health, demographic and lifestyle characteristics with respect to social networks.ResultsHigher scores for confidant networks were protective against nursing home use (odds ratio [OR] upper versus lower tertile of confidant networks = 0.50; 95%CI 0.33–0.75). Similarly, a significant effect of upper versus lower total network tertile on nursing home use was observed (OR = 0.62; 95%CI 0.43–0.90). Evidence of an effect of children networks on nursing home use was equivocal. Nursing home use was not predicted by other relatives or friends social networks. Use of lower-level residential care was unrelated to social networks of any type. Social networks of any type did not have a significant effect upon low-level residential care use.DiscussionBetter confidant and total social networks predict nursing home use in a large cohort of older Australians. Policy needs to reflect the importance of these particular relationships in considering where older people want to live in the later years of life.

Help or Hindrance? How Family and Friends Influence Chronic Illness Self-Management among Older Adults

We contribute to knowledge about older adults with chronic illnesses by identifying positive and negative influences of family and friends on self-management. Thirteen focus groups were conducted in upstate New York with 84 African American and White men and women, 65 years old or older, with arthritis, diabetes, and/or heart disease. Specific positive and negative social network influences are discussed in the areas of disease management (medication management, dietary activities, physical activity, and health care appointments); decision-making about the illness; and psychosocial coping. Overall, we found many more positive than negative social network influences, and more negative influences from family members than from friends. We discuss differences between influences of family members versus friends, and point out a few suggestive differences by gender and race. We conclude with limitations of the study as well as implications for the design of self-management interventions involving family members and friends.

The Rise and Demise of a Collection of Human Fetuses at Mount Holyoke College

When I found myself at the center of a controversy over the disposition of an old collection of human fetal specimens at Mount Holyoke College, I was motivated to explore the historical transformation that turned embryo collecting for research and pedagogical purposes from a noble to a disparaged practice, and dead fetuses from prized anatomical specimens to ugly, anomalous entities. Using Linda Layne's analysis of the literal and symbolic erasure of dead fetuses from American cultural discourse, this article examines the shifting circumstances that once encouraged the collection of fetal specimens but that now mandate their disappearance. Using Mount Holyoke as a case study, it describes the scientific logic and specific social exchange networks that led to the acquisition of hundreds of fetal specimens in the first half of the 20th century. It also examines the factors--including changes in biology education, concerns about handling hazardous fixatives, and especially the prominence of beautified and lifelike fetal images consistent with the so-called "culture of life"--that prompt the dissolution and demise of human embryo and fetal collections.

Does Diagnosis Matter? Differential Effects of 12-Step Participation and Social Networks on Abstinence

Previous studies that have examined the effects of specific aspects of 12-step participation and social network composition on abstinence have focused mostly on alcohol-related outcomes and have screened out drug dependent persons. This article explores whether these predictors differentially affect abstinence based on DSM-III-R substance dependence disorder (alcohol dependence, drug dependence, and both alcohol and drug dependence). A heterogeneous community sample of treatment seekers (N = 302) randomized to day treatment programs were followed at 6 and 12 months. Bivariate and multivariate regression models were used to test whether engagement in 12-step practices and social network influences to drink or use drugs predicted total abstinence from alcohol and drugs differentially by dependence disorder. Chi-square automatic interaction detector (CHAID) segmentation analyses were then conducted to identify the specific 12-step activities and social network thresholds that best distinguished higher rates of abstinence in each dependence category. Results showed that the number of 12-step meetings attended and number of prescribed 12-step activities engaged in similarly predicted abstinence for alcoholics, drug addicts, and those dependent on both alcohol and drugs. However, specific activities were associated with abstinence differentially by dependence disorder. While many activities differentiated abstinence for drug addicts and those dependent on both alcohol and drugs, for alcoholics only two Alcoholics Anonymous (AA) activities distinguished abstinence (having a sponsor and doing service). Key predictors of abstinence (CHAID) varied by follow-up and dependence disorder, except for doing service in AA and/or Narcotics Anonymous, which was the only specific 12-step activity that was a best predictor of abstinence in all three categories one year following treatment. Thus, “giving back” to one's peer community through service work, an important 12-step belief, seems to be universally valuable later in recovery. As for social network influences, a multivariate regression model showed that having a higher proportion of abstinent individuals in the network was associated with abstinence for alcoholics at 6 months only and for drug dependent persons at 12 months only. CHAID models supported these results and provided specific thresholds for 12-step measures (e.g., >20 meetings for alcoholics, 2 or more nondrinkers in the social network, 3 or more persons supporting reduction for those dependent on both alcohol and drugs, and having 2 or more nondrinkers for those dependent on drugs only). These results support the value of treatment providers prioritizing certain 12-step-related practices and social network changes based on their client dependence profiles. Early on, those with an alcohol diagnosis need to make a commitment to meetings and obtain a sponsor; also, they need to place themselves in a network that encourages sobriety. Early on, those who are drug-dependent-only especially need to become connected with 12-step programs to the extent that they consider themselves a member, and, later, saturate themselves in a highly supportive and predominantly nondrinking environment. Alcohol and drug dependent clients need more intense ongoing 12-step involvement (sponsor and meetings) as well as having nondrinking individuals and people supportive of abstinence in their network. For all clients, doing service is especially important at the longer 12-month posttreatment timeframe.

Are there more than cross-sectional relationships of social support and support networks with functional limitations and psychological distress in early rheumatoid arthritis? the European Research on Incapacitating Diseases and Social Support Longitudinal Study.

To investigate whether greater social support and support network are cross-sectionally associated with less functional limitations and psychological distress in patients with early rheumatoid arthritis (RA); whether this association is constant over time; and whether increases in social support or support network are associated with less functional limitations and psychological distress. Subjects were from the European Research on Incapacitating Diseases and Social Support cohort and had early RA. Social support, support network, functional limitations (Health Assessment Questionnaire), and psychological distress (General Health Questionnaire) were assessed annually. Variance and covariance analyses with repeated measures were performed. A total of 542 subjects were assessed for 3 years. On average, patients with a greater amount of specific social support or a stronger specific support network experienced less functional limitation and less psychological distress. Changes in a given subject's functional limitations and psychological distress did not depend on his or her baseline social support or support network. Neither social support nor support network change over time. There may be a cross-sectional link between specific social support or support network and functional limitations and psychological distress, but no longitudinal association could be evidenced.

The effects of social networks on disability in older Australians.

To investigate the effects of total social networks and specific social networks with children, relatives, friends, and confidants on disability in mobility and Nagi functional tasks. Six waves of data from the Australian Longitudinal Study of Ageing were used. Data came from 1,477 participants aged 70 years or older. The effects of total social networks and those with children, relatives, friends, and confidants on transitions in disability status were analyzed using binary and multinomial logistic regression. After controlling for a range of health, environmental, and personal factors, social networks with relatives were protective against developing mobility disability (OR = 0.89; 95% CI = 0.79 to 1.00) and Nagi disability (OR = 0.85; 95% CI = 0.74 to 0.96). Other social subnetworks did not have a consistent effect on the development of disability. The effects of social relationships extend beyond disability in activities of daily living. Networks with relatives protect against disability in mobility and Nagi tasks.

The Circuit Trainer’s Habitus: Reflexive Body Techniques and the Sociality of the Workout

In this article I discuss some of the findings of an on-going ethnographic study of two once-weekly circuit training classes held in one of the growing number of private health and fitness clubs. The article has four aims. First, to demonstrate and explore the active role of the body in a central practice of body modification/maintenance: i.e. circuit training. Second, to demonstrate that circuit training is a social structure which both shapes the activity of the agent and is shaped by that (shaped) agent. I aim also to explore this structuration process. Third, to draw out a number of aspects of the sociality of body maintenance/modification. Training, I argue, is a form of symbolic interaction, localized within specific and durable social networks. The final aim of the article is to weave these various claims together into a coherent overall account of circuit training as a form of body modification. As an investigation of the embodied nature of practices of body maintenance and the active role of social agents in relation to these practices the article rejoins an important strand of sociological investigations of ‘the body’. At the same time, however, the article seeks to challenge those approaches, often rooted in Foucauldian analysis, which portray the body as ‘docile’ in relation to body maintenance. Foucauldian inspired studies often reify practices of modification as ‘technologies’ or ‘apparatuses’, ignoring the active role of embodied agents in these practices and eliding the difference between texts which prescribe ways of acting and the more messy and complex reality of those ways of acting.

Economic Geography and European Finance

This report summarises the scientific content and results of the European Science Foundation Exploratory Workshop on 'Economic Geography and European Finance' held at Jesus College, Oxford University, 16-19 September 2004. The objective of the workshop was to further our understanding of the links between finance and space in the European context, through a cross-examination of ideas between the growing field of economic geography and the geographical perspectives applied in other social sciences including financial economics, political science, sociology as well as management and business studies. With this objective in mind the workshop was organised as a series of six sessions: European finance between globalisation and localisation, stock markets, corporate governance, venture capital, financial centres and banking. The workshop papers stressed the complementarity between quantitative and qualitative research. Still little is known empirically about the spatial flows of capital and finance in Europe, partly due to the lack of comparative data. On the other hand, while we are witnessing is a rebirth of geography in academic literature on finance, there are definite limits of modelling and quantitative methodology traditionally applied in financial economics. As the workshop has highlighted real-world space escapes any easy quantification, and has to be treated as a multi-dimensional concept incorporating distance, political borders, cultural proximity, as well as inclusion in and exclusion from specific social networks. In addition, the workshop has identified promising areas for future interdisciplinary research on European financial markets and institutions.

‘Widening the radius of trust’: ethnographic explorations of trust and Indian business

Trust has latterly become an important focus of enquiry across the social sciences, and this article reflects critically upon the current literature on the basis of ethnographic research into the transactions of small companies in several sectors of Indian industry, and the reorganization that is taking place in Indian family business groups in the context of economic globalization. It is concluded that much of the argument about the increasing importance of trust in the context of globalization is misplaced, and that it serves an ideological function. The problem of business management in India is that of bringing about change in the institutional framework and in business behaviour in a context in which these changes confront a culture of ‘selective trust’ amongst groups of people in specific social networks.

Non-Markov stochastic dynamics of real epidemic process of respiratory infections

The study of social networks and especially of stochastic dynamics of diseases spread in human population has recently attracted considerable attention in statistical physics. In this work we present a new statistical method of analyzing the spread of epidemic processes of grippe and acute respiratory track infections (ARTI) by means of the theory of discrete non-Markov stochastic processes. We use the results of our last theory (Phys. Rev. E 65 (2002) 046107) to study statistical memory effects, long-range correlation and discreteness in real data series, describing the epidemic dynamics of human ARTI infections and grippe. We have carried out the comparative analysis of the data of the two infections (grippe and ARTI) in one of the industrial districts of Kazan, one of the largest cities of Russia. The experimental data are analyzed by the power spectra of the initial time correlation function and the memory functions of junior orders, the phase portraits of the four first dynamic variables, the three first points of the statistical non-Markov parameter and the locally averaged kinetic and relaxation parameters. The received results give an opportunity to provide a strict quantitative description of regular and stochastic components in epidemic dynamics of social networks taking into account their time discreteness and effects of statistical memory. They also allow to reveal the degree of randomness and predictability of the real epidemic process in the specific social network.

Social Network Ties and Strategic Renewal: Promotion of Strategic Initiatives by Middle-Level Actors

Social Network Ties and Strategic Renewal: Promotion of Strategic Initiatives by Middle-Level Actors

Mounting anomalies in the epidemiology of HIV in Africa: cry the beloved paradigm.

In North America Europe and many parts of Asia the ignition of regional epidemics and rapid HIV transmission has been associated principally with the sharing of contaminated injecting equipment and with anal intercourse. Though heterosexual intercourse has been virtually the sole explanation offered for the AIDS epidemic in sub-Saharan Africa to our knowledge in no other part of the world has penile-vaginal exposure (as opposed to “heterosexual sex”) been demonstrated to initiate or sustain rapid HIV propagation. HIV is not transmitted by “sex” but only by specific risky practices. It is not transmitted by “injections” but only by contaminated implements which need to be clearly differentiated as to type and frequency of injection and by the conditions of the exposure setting. In virtually all societies affected by HIV to date both routes seem to play important roles. If we are to understand and intervene in each of these epidemics well-designed studies at both the population and individual levels are urgently needed. It is vital that these be properly controlled for parenteral exposure specific sexual practices and other co-factors and the complex and specific social patterns and networks that accompany them.

Substance Abuse and HIV: Considerations With Regard to Methamphetamines and Other Recreational Drugs for Nursing Practice and Research

Substance use continues to be closely associated with both HIV infection and treatment considerations in all at-risk populations. Among those groups heretofore not well characterized epidemiologically or clinically are those dual-risk men who have sex with other men (MSM) and use and/or inject drugs. Of particular current concern with regard to drug-using MSM is the growth in popularity of a group of recreational or so-called party drugs associated with specific social and sexual environments and networks. Chief among these drugs are hallucinogens, such as MDMA, ketamine, and GHB, and stimulants, such as cocaine, amphetamines, and methamphetamine. Increased methamphetamine use by MSM is particularly alarming because of its reported associations with high-risk injecting and sexual behaviors. Preliminary data are reported from an ethnographic exploration of MSM methamphetamine users in the Pacific Northwest of the United States. Case studies drawn from the data illustrate the complex and variable patterns of methamphetamine use among MSM. Finally, implications for nursing are discussed, and "upstream nursing" is suggested as a means of patient advocacy for HIV nurses working with substance-using populations.

The staying power of sexually transmitted diseases

Sexually transmitted diseases (STDs) not only have staying power but also appear to be on the increase. Emerging laboratory technologies and improving epidemiological methods have identified more than 25 organisms transmitted by intimate human sexual contact. Based on global serological evidence even more incurable viral infections are transmitted each year via the sexual route. The consequences of these infections remain devastating. However the problem is seen in the collation of multiple microepidemics spread among sexually active individuals who themselves choose sex partners with specific social networks. In this article these microepidemics are examined by considering several interconnected themes. Transmission dynamics suggest that the probability of infecting a susceptible partner can be reduced by promoting use of barrier methods and safer sex practices and the duration of infectiousness can be reduced by early diagnosis and curative treatment. In the context of sexual networks the role of core groups and bridge populations in sustaining the spread of STDs is emphasized. Human rights should be strengthened so as to maximize the effect of individually oriented clinical STD control services and community-based prevention approaches. In addition technical innovations will also help control STDs which consequently will further underscore the importance of human behavior.
