Public Information Influences Sperm Transfer to Females in Sailfin Molly Males

In animals, including humans, the social environment can serve as a public information network in which individuals can gather public information about the quality of potential mates by observing conspecifics during sexual interactions. The observing individual itself is also a part of this information network. When recognized by the observed conspecifics as an audience, his/her presence could influence the sexual interaction between those individuals, because the observer might be considered as a potential mate or competitor. One of the most challenging questions in sexual selection to date is how the use of public information in the context of mate choice is linked to the fitness of individuals. Here, we could show that public information influences mate-choice behaviour in sailfin molly males, Poecilia latipinna, and influences the amount of sperm males transfer to a female partner. In the presence of an audience male, males spent less time with the previously preferred, larger of two females and significantly more time with the previously non-preferred, smaller female. When males could physically interact with a female and were faced with an audience male, three audience females or no audience, males transferred significantly more sperm to a female partner in the presence of an audience male than with female audience or no audience and spent less time courting his female partner. This is the first study showing that public information use turns into fitness investment, which is the crucial factor to understand the role of public information in the dynamic processes in sexual selection.     

The Power of the Web: A Systematic Review of Studies of the Influence of the Internet on Self-Harm and Suicide in Young People

Background

There is concern that the internet is playing an increasing role in self-harm and suicide. In this study we systematically review and analyse research literature to determine whether there is evidence that the internet influences the risk of self-harm or suicide in young people.

Methods

An electronic literature search was conducted using the PsycINFO, MEDLINE, EMBASE, Scopus, and CINAHL databases. Articles of interest were those that included empirical data on the internet, self-harm or suicide, and young people. The articles were initially screened based on titles and abstracts, then by review of the full publications, after which those included in the review were subjected to data extraction, thematic analysis and quality rating.

Results

Youth who self-harm or are suicidal often make use of the internet. It is most commonly used for constructive reasons such as seeking support and coping strategies, but may exert a negative influence, normalising self-harm and potentially discouraging disclosure or professional help-seeking. The internet has created channels of communication that can be misused to ‘cyber-bully’ peers; both cyber-bullying and general internet use have been found to correlate with increased risk of self-harm, suicidal ideation, and depression. Correlations have also been found between internet exposure and violent methods of self-harm.

Conclusions

Internet use may exert both positive and negative effects on young people at risk of self-harm or suicide. Careful high quality research is needed to better understand how internet media may exert negative influences and should also focus on how the internet might be utilised to intervene with vulnerable young people.     

Risk Factors of Internet Addiction among Internet Users: An Online Questionnaire Survey

Backgrounds

Internet addiction (IA) has become a major public health issue worldwide and is closely linked to psychiatric disorders and suicide. The present study aimed to investigate the prevalence of IA and its associated psychosocial and psychopathological determinants among internet users across different age groups.

Methods

The study was a cross-sectional survey initiated by the Taiwan Suicide Prevention Center. The participants were recruited from the general public who responded to the online questionnaire. They completed a series of self-reported measures, including Chen Internet Addiction Scale-revised (CIAS-R), Five-item Brief Symptom Rating Scale (BSRS-5), Maudsley Personality Inventory (MPI), and questions about suicide and internet use habits.

Results

We enrolled 1100 respondents with a preponderance of female subjects (85.8%). Based on an optimal cutoff for CIAS-R (67/68), the prevalence rate of IA was 10.6%. People with higher scores of CIAS-R were characterized as: male, single, students, high neuroticism, life impairment due to internet use, time for internet use, online gaming, presence of psychiatric morbidity, recent suicide ideation and past suicide attempts. Multiple regression on IA showed that age, gender, neuroticism, life impairment, internet use time, and BSRS-5 score accounted for 31% of variance for CIAS-R score. Further, logistic regression showed that neuroticism, life impairment and internet use time were three main predictors for IA. Compared to those without IA, the internet addicts had higher rates of psychiatric morbidity (65.0%), suicide ideation in a week (47.0%), lifetime suicide attempts (23.1%), and suicide attempt in a year (5.1%).

Conclusion

Neurotic personality traits, psychopathology, time for internet use and its subsequent life impairment were important predictors for IA. Individuals with IA may have higher rates of psychiatric morbidity and suicide risks. The findings provide important information for further investigation and prevention of IA.     

Who's Watching Me: Female Siamese Fighting Fish Alter Their Interactions in Response to an Audience

It is well established that interactions between conspecifics are often influenced by the presence of passive bystanders. Individuals have been found to alter their behavior in a variety of contexts, from foraging to aggression, based on the presence, sex, or identity of an audience. This audience effect may influence not only the nature of a signaling event but also the evolution of signal structure as signals may have to convey information across a distance. Additionally, audience individuals may use information obtained by watching in later encounters with these individuals, which may act as a selection pressure on communication. Communication networks in Siamese fighting fish, Betta splendens, are particularly well studied, with audience effects influencing both male–male interactions and male–female interactions. However, the effects of an audience on female–female interactions have not been examined in this species or any other. This study examined the interactions of pairs of females in three different audience conditions (male, female, and no audience). The results suggest that female–female interactions are affected by the presence of an audience as interactant‐directed gill flaring, the most commonly performed behavior, was performed more with an audience present. Additionally, the sex of the audience seemed to be influential, reflected by a difference in the frequency of interactant‐directed behaviors when a female vs. a male audience was present. This study is one of the first to demonstrate that females modify their behavior as a result of being watched and stresses the importance of examining audience effects in a variety of social contexts.     

To Crowdfund Research,Scientists Must Build an Audience for Their Work

As rates of traditional sources of scientific funding decline, scientists have become increasingly interested in crowdfunding as a means of bringing in new money for research. In fields where crowdfunding has become a major venue for fundraising such as the arts and technology, building an audience for one''s work is key for successful crowdfunding. For science, to what extent does audience building, via engagement and outreach, increase a scientist''s abilities to bring in money via crowdfunding? Here we report on an analysis of the #SciFund Challenge, a crowdfunding experiment in which 159 scientists attempted to crowdfund their research. Using data gathered from a survey of participants, internet metrics, and logs of project donations, we find that public engagement is the key to crowdfunding success. Building an audience or “fanbase” and actively engaging with that audience as well as seeking to broaden the reach of one''s audience indirectly increases levels of funding. Audience size and effort interact to bring in more people to view a scientist''s project proposal, leading to funding. We discuss how projects capable of raising levels of funds commensurate with traditional funding agencies will need to incorporate direct involvement of the public with science. We suggest that if scientists and research institutions wish to tap this new source of funds, they will need to encourage and reward activities that allow scientists to engage with the public.     

In search of the Holy Grail: Media discourse and the new human genetics

It has widely been recognized that the media play a key role in framing debates about genetic issues. This paper provides an overview of the major areas of debate within the social scientific literature on media, public understanding of science and human genetics. It evaluates current approaches to assessing the role of the media in influencing public policy debates. It argues that an analysis of the strategies of news sources should occupy a central role in furthering understanding about the ways in which various social actors seek to influence public policy agendas. At present, within the field of human genetics, only a handful of researchers have systematically examined the strategies of news sources from the perspective of the sources themselves. While recent research has focused upon identifying the major sources and how they are used in science reporting, there remains much to be done in uncovering the processes of negotiation and contestation among social actors prior to issues gaining media coverage.     

Context-dependent dispersal,public information,and heterospecific attraction in newts

Dispersal is one of the main processes that determine community structure. Individuals make dispersal decisions according to environmental and/or social cues that reflect the fitness prospects in a given patch. The presence and abundance of heterospecifics within the same ecological guild, and/or their breeding success, may act as public information that influences movement decisions. To date, most studies investigating the role of heterospecific attraction have focused on habitat choice, using both experimental and correlational approaches. The present study is the first to examine how long-term variation in heterospecific density in breeding patches may affect dispersal patterns in spatially structured populations. We investigate how the dispersal decisions of the great crested newt (Triturus cristatus) are related to the variable density of two other newt species, the alpine newt (Ichthyosaura alpestris) and the palmate newt (Lissotriton helveticus). To examine this issue, we used capture–recapture data collected in an experimental pond network over a 20-year period. The results revealed that the great crested newt’s dispersal is context dependent and is affected by variation in heterospecific density: individuals were less likely to emigrate from ponds with high heterospecific density and were more likely to immigrate to ponds with high heterospecific density. These findings suggest that individuals adjust their dispersal decisions at least partly based on public information provided by heterospecifics. This mechanism may play a critical role in the dynamics of spatially structured populations and community functioning.

     

Moving ethnography online: researching Brazilian migrants' online togetherness

Abstract

This article contributes to recent scholarship on the changing nature of fieldwork practices within migration research, focusing on the practice of online ethnography. It makes a case for the significance of the internet and, more specifically, social network sites, in the experience of many migrants. I state that online togetherness is an integral part of the lives of many migrants which also interrelates with ‘offline’ aspects of their social lives. Therefore, I argue that current research on migration would benefit from a more balanced combination of offline and online ethnography, taking into account how online connectivity affects the nature of migration and the conditions of being a migrant. Methodologically, I suggest that ethnography is well suited for generating understandings of the significance of the internet in the experience of migrants, but that a number of adjustments in methods of data collection and analysis must be made.     

Audience Type and Receptivity Affect Male–Female Interactions in Siamese Fighting Fish

The study of communication in a network setting has gained increasing popularity in recent years. While audience effects on aggressive interactions have been studied extensively, male–female interactions have often been overlooked. In addition, little is known about how reproductive status affects the nature of audience effects. Siamese fighting fish, Betta splendens, are a popular subject for communication network studies, but male–female interactions have not been explored in this setting. In this study, pairs of male and female Betta were presented with a male, female or no audience to determine whether the presence of an audience alters the behaviour of the interactants. Within these three audience types, there were four reproductive status conditions with receptivity indicated by nest presence for males and reproductive barring for females. It was predicted that male–female interactions would be affected by the presence of an audience, especially when both interactants are receptive as has been found in male–male interactions in this species. The results suggest that presence of an audience and reproductive status act in combination to influence male–female interactions, but only in interactant‐directed behaviours. Not all behaviours were equally affected by these factors. For example, while tail beats to the other interact were greatest when a female audience was present and both the interactants were receptive, this was not true for gill flaring. This study is among the first investigations into audience effects on male–female interactions including the first in Betta and suggests that courtship as well as aggression should be explored in a network setting.     

Altruism can evolve when relatedness is low: evidence from bacteria committing suicide upon phage infection

High relatedness among interacting individuals has generally been considered a precondition for the evolution of altruism. However, kin-selection theory also predicts the evolution of altruism when relatedness is low, as long as the cost of the altruistic act is minor compared with its benefit. Here, we demonstrate evidence for a low-cost altruistic act in bacteria. We investigated Escherichia coli responding to the attack of an obligately lytic phage by committing suicide in order to prevent parasite transmission to nearby relatives. We found that bacterial suicide provides large benefits to survivors at marginal costs to committers. The cost of suicide was low, because infected cells are moribund, rapidly dying upon phage infection, such that no more opportunity for reproduction remains. As a consequence of its marginal cost, host suicide was selectively favoured even when relatedness between committers and survivors approached zero. Altogether, our findings demonstrate that low-cost suicide can evolve with ease, represents an effective host-defence strategy, and seems to be widespread among microbes. Moreover, low-cost suicide might also occur in higher organisms as exemplified by infected social insect workers leaving the colony to die in isolation.     

The Impact of Guide Dogs on the Identity of People with Visual Impairments

ABSTRACT

This paper explores the effect of peoples' association with guide dogs on how they understand and feel about themselves and how they are regarded by those with whom they interact. The concepts of personal, collective, and social identity are used to situate the discussion. Of central importance is the way working with a guide dog shapes public interaction and how owner' self definitions and social identities are extended by being intimately involved in the owner—dog team.     

The Gender of the Joke: Intimacy and Marginality in Murri Humour

ABSTRACT

Murri Aboriginal humour performances are expressive events in which bodily experiences of policing and agency are discursively commented on in ways that expose Australia's naturalised rationalisations of indigenous governance. Drawing on the ‘out-of-the-way’ position of an indigenous minority encapsulated in the body of the nation-state and the Murri body's intimate ‘out-of-the-way’ folds and crannies, Murri humour delimits and mocks the marginal location Murri people are imagined to spatially and morally occupy within Australia. This work examines how gendered humour renders the Murri individual and social body legible to and for a Murri audience. Such humour performances engage the local and the global, the modern and the traditional, and the hegemonic and the counter-hegemonic in ways that link intimacy, bodies and embodiments to these macro-processes. Unraveling such binaries produces a nuanced analysis in which embodied social actions and sly social critique are captured as they are experienced and expressed through humour.     

THE GROWING PROBLEM OF SUICIDE

Informed as to the epidemiologic aspects of suicide and as to warning signs, physicians could, by appropriate action, prevent self-destruction in many cases.Not only ought each physician''s office be a suicide prevention station, but all physicians ought to act in concert to gather data, to carry out a program of public instruction and to enlist the aid of the press in an effort to reduce the ever-increasing rate of suicide.     

Suicidal Performances: Voicing Discontent in a Girls’ Dormitory in Kabul

Female suicide in Afghanistan has generally been given economic and psychological explanations. More rarely has its social dimension been analysed. In this paper, I underline the communicative potential of Afghan women's suicide in the 'post-war/reconstruction' context. I highlight its ambiguous symbolic power and its anchorage in the subversive imaginary universe of women's poetic expression. I argue that while reproducing certain cultural ideas about women's inherent emotional fragility, women's suicide also challenges the honour system in powerful ways and opens possibilities for voicing discontent. I qualify female suicide as the 'art of the weak' (De Certeau 1980, 6), a covert form of protest, a performance-in the sense of Bauman (2004)-that builds upon traditional popular 'knowledge' about gender in order to manage the impression of an audience and make women's claims audible.     

Morals,suicide, and psychiatry: a view from Japan

In this paper, I argue that within the Japanese social context, the act of suicide is a positive moral act because the values underpinning it are directly related to a socially pervasive moral belief that any act of self–sacrifice is a worthy pursuit. The philosophical basis for this view of the self and its relation to society goes back to the writings of Confucius who advocated a life of propriety in which being dutiful, obedient, and loyal to one's group takes precedence over the desires of the individual selves that make up the group. I argue that this philosophical perspective poses formidable challenges to Japanese psychiatry (which accepts a contrary western perspective) because, as western psychiatry is based on the concept of autonomous individuality, the Japanese conceive of the self as socially embedded. Because suicide in Japan is viewed as a potentially honorable, virtuous, and even beautiful act of self–sacrifice expressing one's duty to one's group, the western perspective is quite foreign to the Japanese self–conceptual framework. Therefore, since Japanese psychiatry and law have embraced the western medical tradition of viewing suicide as a non–rational response to mental illness, which runs counter to the cultural view that suicide is a moral (and rational) act, I argue that western explanations of suicide present significant cross–cultural problems for Japanese psychiatry.     

Running a Question-and-Answer Website for Science Education: First-Hand Experiences

The online learning and outreach resource Ask A Biologist (AAB; ) has been operating for three years, and this paper reports our initial experience of running the site. To date, AAB has answered and archived online over 3,500 questions from the general public with contributions from more than 50 researchers, and attracted an estimated audience of half a million, all with relatively minimal investment. Simply, questions are posted by visitors to the site, and one or more of our registered academic experts then provide their answers which are available for all to see and browse. The system is simple and provides direct contact between the public and scientists on subjects that are guaranteed to be of interest. In this paper, we review the benefits and drawbacks of such a system based on our first-hand experiences, detailing how the site was originally conceived and built and how it operates. We offer this as a model for future projects and to highlight both the benefits and pitfalls of such a system.     

Opportunities for improving risk communication during the permitting process for entomophagous biological control agents: a review of current systems

Concerns about potentially irreversible non-target impacts from the importation and release of entomophagous biological control agents (BCAs) have resulted in increasingly stringent national import requirements by National Plant Protection Organizations worldwide. However, there is a divergence of opinions among regulators, researchers, environmentalists, and the general public on ways to appropriately manage associated risks. Implementation of a comprehensive and effective risk communication process might narrow the opinion gaps. Results from a comprehensive survey conducted in the United States were used to describe communication habits of stakeholders involved in biological control and identify areas that are fundamental in an efficient process. In addition, this study critically reviews risk communication practices and how phytosanitary decisions are communicated in the permitting systems for entomophagous BCAs of several countries to identify risk communication tools used in an effective risk communication framework. The following barriers to efficient risk communication were identified: absence of a formalized risk communication process, undefined risk communication goals and target audiences, lack of credibility and objectivity of information sources, inefficiency of mode of distribution of messages, insufficient public participation, and lack of transparency of decision making processes. This paper suggests the creation and/or enhancement of modes of distribution of risk messages to increase coverage, understanding, and guidance. For instance, messages should be presented in different formats such as internet, brochures, and newspapers. Surveys, public meetings, and trainings/workshops are tools that can be used to characterize stakeholders’ diversity and develop risk messages specific to the targeted audience. Implementation of a participatory decision making process will increase stakeholder involvement and trust in the risk management plan. Development of practical mechanisms, such as public hearings will increase all stakeholders’ involvement in the risk assessment process. A clear framework describing how public comments will be incorporated in the decision making process should be implemented. Finally, to ensure a streamlined risk communication process, there must be consistency in the messages disseminated by federal, state, and local agencies.     

Biotechnology,people and markets

In assessing the likely demand for biotechnology products it is not sufficient just to look at what is happening in firms and their immediate market environment. There is no one 'market' for biotechnology products: there are differences between sectors and between countries. You have instead to look at the institutional contexts of the biotechnology product's development. This paper reviews work which has been carried out by social scientists, especially those using 'social shaping' approaches, on the development of new products based on advances in biotechnology and on the creation of markets to go with these products. It examines work on public attitudes to the exploitation of the technology, focusing especially on the issue of social inclusion and exclusion and how biotechnology might make exclusion more likely. It concludes by considering what current differences in public attitudes to the development of some biotechnology-based products might mean for the development of markets for those products in the UK.     

No Evidence for Audience Effects in Reciprocal Cooperation of Norway Rats

Norway rats (Rattus norvegicus) cooperate according to indirect reciprocity, which implies the involvement of a reputation mechanism. Here, we test whether the rats employ such mechanism in repeated cooperative interactions. Focal subjects were first trained individually to pull food towards a social partner. During the experiment, the focal rats were confronted with two types of trained social partners: one always cooperated and the other one always defected, either in the presence or in the absence of an audience. Based on the hypotheses that the rats possess a reputation mechanism involving image scoring, we predicted them to be more helpful in the presence of an audience, independently of the partner's cooperative behaviour. If, in contrast, reputation involved a standing strategy, we predicted the rats to distinguish more between cooperators and defectors in the presence of an audience than in its absence. The rats helped cooperative partners more than defectors, but against both predictions the presence or absence of an audience did not influence their helping propensity. This indicates that either reputation is not included in the decision of rats to help an individual that has helped others, or that reputation is neither involving image scoring nor a standing strategy. Although the rats have been shown to modulate their decision to help a social partner based on its helpful behaviour towards others, they do not seem to adjust their behaviour strategically to the presence of an audience.     

Social life cycle assessment: in pursuit of a framework for assessing wood-based products from bioeconomy regions in Germany

Purpose

With many policies in Germany steering towards a bioeconomy, there is a need for analytical tools that assess not only the environmental and economic implications but also the social implications of a transition to a bioeconomy. Wood is expected to become a major biomass resource in bioeconomy regions. Therefore, this paper develops a social life cycle assessment (sLCA) framework that can be applied specifically to a wood-based production system in one of Germany’s bioeconomy regions.

Methods

This paper reviews and analyses existing sLCA approaches, in terms of how applicable they are for assessing a wood-based production system in a German bioeconomy regional context. The analysis is structured according to the standard phases of environmental life cycle assessment (LCA). However, we use the term social effects rather than social impacts, to acknowledge the unknown cause–effect relationship between an organisation’s activities and its social impacts. We also consider the establishment of regional system boundaries, as well as the relationship between the social effects and the product being assessed. Additionally, an approach for the development and selection of social indicators and indices is outlined. Furthermore, we discuss data requirements and present an approach for a social life cycle impact assessment method.

Results and discussion

A new conceptual framework for a context-specific sLCA to assess wood-based products manufactured in a bioeconomy region was developed. It enables sLCA practitioners to identify “social hotspots” and “social opportunities” from a regional perspective. The location and characteristics of these social hotspots and opportunities can be analysed, in particular, for major production activities in a bioeconomy region in Germany. Therefore, according to this framework, the development of social indices and indicators, the collection of data and the approach used for characterising social effects need to relate to the geographical context of the product being assessed. The proposed framework can, thus, help to identify, monitor and evaluate the social sustainability of wood-based bioeconomy chains in a regional context.

Conclusions

This framework requires a high level of detail in the social inventory and impact assessment phase, in order to assess the regional foreground activities in a German wood-based bioeconomy region. It enables sLCA studies to identify which social hotspots and social opportunities occur and where they are located in the wood-based production system of a regional bioeconomy.
