Whatever happened to Kony2012? Understanding a global Internet phenomenon as an emergent social identity

Kony2012 was a viral Internet video that attracted unprecedented online interest in promoting a campaign to arrest the leader of an African militant group. The current research considers the social psychological bases of social media‐based collective action. In three cross‐sectional surveys (N = 304) collected before, on, and after the key action date of 20 April 2012, we consider the nature (opinion based or global) and function (emergent or transforming) of social identity in modern forms of social action. Multigroup structural equation modelling showed that Kony2012 action was best captured by an emergent opinion‐based social identity. Moreover, the same factors that predicted Kony2012 action generally also predicted engagement in new repertoires of protest (involving the use of social media) and an observable traditional socio‐political action (signing a letter to a government minister). The results suggest that there is no sharp dividing line between traditional and new forms of collective action and that both may be understood as valid expressions of collective selfhood.

Atomic imaging of the interface between M23C6-type carbide and matrix in a long-term ageing polycrystalline Ni-based superalloy

Besides the well-known cube-on-cube orientation relationship (OR) between M₂₃C₆ carbide and matrix, we have determined a new OR named as the twin-related OR in a long-term ageing Ni-based superalloy on the basis of the extensive and detailed electron diffraction analyses. Furthermore, by means of atomic-resolution high angle annular dark-field imaging technique which is implemented in the aberration-corrected scanning transmission electron microscope, we elucidated the interfacial characteristics between M₂₃C₆ and matrix for above two types of ORs. Taking into account of the interfacial characteristics, we propose that the twin-related OR possesses a higher total interfacial energy. Thus, its frequency of occurrence is lower than that of the cube-on-cube OR though both ORs are usually seen in the long-term ageing samples.     

Not all semantics: Similarities and differences in reminiscing function and content between Indigenous and non-Indigenous Australians

This study explored why and how Indigenous and non-Indigenous Australians remember the past. Indigenous Australians traditionally share a strong oral tradition in which customs, personal and cultural histories, and other narratives are passed across groups and between generations by word of mouth. Drawing on this tradition, in which inherent value is placed on sharing knowledge and maintaining connectedness with others, we hypothesised that Indigenous Australians would be more likely than non-Indigenous Australians to report reminiscing to fulfil social functions (but not self or directive functions). Furthermore, we hypothesised that Indigenous Australians would recall personal past experiences more elaborately than would non-Indigenous Australians. In Study 1, 33 Indigenous Australians and 76 non-Indigenous Australians completed Webster's Reminiscence Functions Scale. As predicted, Indigenous participants reported higher scores on subscales related to social functions than did non-Indigenous Australians: particularly “Teach/Inform” and “Intimacy Maintenance”. They also scored higher on the “Identity” subscale. In Study 2, 15 Indigenous and 14 non-Indigenous Australians shared three memories from the distant and recent past. While Indigenous and non-Indigenous narratives did not differ in either emotion or elaboration, Indigenous Australians provided more memory context and detail by including a greater proportion of semantic memory content. Taken together, these findings suggest differences in both why and how Australians remember.     

The Effects of Stress on the Lives of Emerging Adult College Students: An Exploratory Analysis

This study systematically analyzed the personal reports of 20 emerging adult college students with regard to how stress affects their lives. Qualitative analyses revealed that stress influenced students' lives in both positive and negative ways. Implications of these findings for physical and mental health are discussed. Recommendations for counseling practice are provided.     

The (Non) Religion of Mechanical Turk Workers

Social science researchers have increasingly come to utilize Amazon's Mechanical Turk (MTurk) to obtain adult, opt‐in samples for use with experiments. Based on the demographic characteristics of MTurk samples, studies have provided some support for the representativeness of MTurk. Others have warranted caution based on demographic characteristics and comparisons of reliability. Yet, what is missing is an examination of the most glaring demographic difference in MTurk—religion. We compare five MTurk samples with a student convenience sample and the 2012 General Social Survey, finding that MTurk samples have a consistent bias toward nonreligion. MTurk surveys significantly overrepresent seculars and underrepresent Catholics and evangelical Protestants. We then compare the religiosity of religious identifiers across samples as well as relationships between religiosity and partisanship, finding many similarities and a few important differences from the general population.     

Serial killers,spiders and cybersex: Social and survival information bias in the transmission of urban legends

This study uses urban legends to examine the effects of the social information bias and survival information bias on cultural transmission across three phases of transmission: the choose‐to‐receive phase, the encode‐and‐retrieve phase, and the choose‐to‐transmit phase. In line with previous research into content biases, a linear transmission chain design with 60 participants aged 18–52 was used to examine the encode‐and‐retrieve phase, while participants were asked to rank their interest in reading the story behind a headline and passing a story on for the other two phases. Legends which contained social information (Social Type), legends which contained survival information (Survival Type), and legends which contained both forms of information (Combined Type) were all recalled with significantly greater accuracy than control material, while Social and Combined Type legends were recalled with significantly greater accuracy than Survival Type legends. In another study with 30 participants aged 18–22, no significant differences were found between legend types in either the choose‐to‐receive phase or the choose‐to‐transmit phase.
