Identifying the genealogical self

What is the connection between archives and identity? One of the main user groups of archives are family historians who often state that they undertake to find out about their ancestry in order to ??find out who they are??. But what does such a claim mean, where did it come from and what is the role of archives in this search for the self? This article explores these questions by examining two modern genealogical texts: Alex Haley??s Roots (1976) and the television programme, Who Do You Think You Are? (2004). These narratives show that archives can be part of the articulation of the self and that they have the potential to disclose the who beyond the private confines of the family to the reader or television audience. In this way, the archive has become a theatre of meaning, memory and self-identity, a performative space in which identities are enacted. The paper concludes by arguing that the connection between archives and identity can be a complex-layered performance that not only articulates the self but also has the potential to connect the self to the other. Such an exploration of the imaginative and performative aspects of archives within such genealogical storytelling is important if we are to further our understanding of the role of archives in contemporary Western society.     

Vertical microbubble column–A photonic lab-on-chip for cultivation and online analysis of yeast cell cultures

This paper presents a vertically positioned microfluidic system made of poly(dimethylsiloxane) (PDMS) and glass, which can be applied as a microbubble column (μBC) for biotechnological screening in suspension. In this μBC, microbubbles are produced in a cultivation chamber through an integrated nozzle structure. Thus, homogeneous suspension of biomass is achieved in the cultivation chamber without requiring additional mixing elements. Moreover, blockage due to produced carbon dioxide by the microorganisms—a problem predominant in common, horizontally positioned microbioreactors (MBRs)—is avoided, as the gas bubbles are released by buoyancy at the upper part of the microsystem. The patterned PDMS layer is based on an optimized two-lithographic process. Since the naturally hydrophobic PDMS causes problems for the sufficient production of microbubbles, a method based on polyelectrolyte multilayers is applied in order to allow continuous hydrophilization of the already bonded PDMS-glass-system. The μBC comprises various microelements, including stabilization of temperature, control of continuous bubble formation, and two optical configurations for measurement of optical density with two different sensitivities. In addition, the simple and robust application and handling of the μBC is achieved via a custom-made modular plug-in adapter. To validate the scalability from laboratory scale to microscale, and thus to demonstrate the successful application of the μBC as a screening instrument, a batch cultivation of Saccharomyces cerevisiae is performed in the μBC and compared to shake flask cultivation. Monitoring of the biomass growth in the μBC with the integrated online analytics resulted in a specific growth rate of 0.32 h⁻¹, which is almost identical to the one achieved in the shake flask cultivation (0.31 h⁻¹). Therefore, the validity of the μBC as an alternative screening tool compared to other conventional laboratory scale systems in bioprocess development is proven. In addition, vertically positioned microbioreactors show high potential in comparison to conventional screening tools, since they allow for high density of integrated online analytics and therefore minimize time and cost for screening and guarantee improved control and analysis of cultivation parameters.     

Everything is illuminated: What big data can tell us about teacher commentary

What happens to writing instructors’ feedback when they use a common rubric and an online tool to respond to student papers in a first-year composition course at a large state university in the United States? To investigate this question, we analyze the 118,611 comments instructors made when responding to 17,433 student essays. Using concordance software to quantify teachers’ use of rubric terms, we found instructors were primarily concerned with global, substantive, higher-order concerns—such as responding to students’ rhetorical situations, use of reason, and organization—rather than lower-order concerns about grammar or formatting. Given past research has determined teachers overemphasize lower-order concerns such as grammar, mechanics, and punctuation (Connors and Lunsford, 1988, Lunsford and Lunsford, 2008, Moxley and Joseph, 1989, Moxley and Joseph, 1992, Schwartz, 1984, Sommers, 1982, Stern and Solomon, 2006), these results may suggest the possibility of a generational shift when it comes to response to student writing. Aggregating teacher commentary, student work, and peer review responses via digital tools and employing concordance software to identify big-data patterns illuminates a new assessment practice for Writing Program Administrators—the practice of Deep Assessment.     

A Comparative Content Analysis of Anti- and Prosocial Rap Lyrical Themes Found on Traditional and New Media Outlets

Previous studies investigated the content of rap music within the context of traditional media and found that rap often contains antisocial themes associated with negative effects. The current content analysis investigates whether rap’s lyrical themes consumed and shared online are more diverse and less anti-social than rap aired on traditional outlets. The analysis revealed that songs shared on Facebook were less antisocial and more prosocial than the songs that made the Billboard charts. Additionally, online lyrical themes were more diverse than traditionally distributed lyrics. Rap consumption and sharing behaviors will be discussed in light of the theory of selective exposure     

The perceived value of work placements and part-time work and its diminution with time

This paper explores the perceptions of degree students at two UK universities regarding their work placement and part-time working activities, to assess if the two activities converge. The research comprises three stages: interviews for preliminary exploration of students’ perceptions towards work placement and part-time work; interviews to examine how placement opportunities link with career aspirations; a survey of students who had completed a placement, and those currently on placement. Students acknowledged part-time working helped their placement activity, providing transferable skills beneficial to both study and career aspirations. A significant finding was with respect to time: the closer to the placement activity the data was collected, the stronger the impact of appreciating the value of placement. The paper therefore highlights the value of timing in the assessment of work placement. It also offers value for universities’ by providing insight into students’ perceptions regarding embedded external work activities that can enhance graduate employability and career prospects.     

Bullying and social support: variation by school-type and emotional or behavioural disturbances

The present study analysed whether bullying/victimisation and related social support vary by emotional and behavioural disturbances (EBD) as well as school type. We examined 540 German adolescents with and without emotional disturbances (ED)/behavioural disturbances (BD) attending regular and special schools for students with EBD. Adolescents with BD and co-morbid co-occurring emotional and behavioural disturbances (ED + BD) reported elevated levels of bullying, while students with ED and co-morbid ED + BD reported elevated levels of victimisation. Enhanced levels of overt victimisation were also found in adolescents from special schools. Students from special schools perceived less peer support but more teacher support. Furthermore, adolescents with co-morbid ED + BD were least likely to tell teachers about being victimised. It is concluded that bullying interventions for adolescents with EBD and students from special schools need to be implemented and evaluated.     

Values-Alignment Messaging Boosts Adolescents’ Motivation to Control Social Media Use

Two preregistered experiments with 2,733 U.S. high school students (age range = 13–19 years) compared the impact of different messages on adolescents’ motivation to control social media use (SMU). A traditional message emphasized the benefits of avoiding SMU, whereas a values-alignment message framed controlling SMU as being consistent with autonomy and social justice. Compared to no message or a traditional message, in both studies, a values-alignment message led to greater motivation to control SMU immediately afterward, and in Study 2, awareness of “addictive” social media designs 3 months later. As hypothesized, values-alignment messaging was more motivating for girls than boys. Results offer preliminary support for leveraging adolescents’ drives for autonomy and social justice to motivate self-regulation of SMU.     

Books and babies

One of the most satisfying forms of verbal communication between child and adult is that magical moment of being read to. Read me a story is the preschooler's frequent refrain, and even the youngest toddler will manage self and book into the cozy lap of a willing adult.Reprinted by permission of the publisher from Nuba-Scheffler, Hannah, Sheiman, Deborah Lovitky, & Watkins, Kathleen Pullan, INFANCY: A GUIDE TO RESEARCH & RESOURCES.
