Cyanobacteria and microalgae in supporting human habitation on Mars
Get PDFEstablishing the first human presence on Mars will be the most technically challenging undertaking yet in the exploration beyond our planet. The remoteness of Mars from Earth, the inhospitable surface conditions including low atmospheric pressure and cold temperatures, and the need for basic resources including water, pose a formidable challenge to this endeavour. The intersection of multiple disciplines will be required to provide solutions for temporary and eventually permanent Martian habitation. This review considers the role cyanobacteria and eukaryotic microalgae (collectively referred to here as ‘microalgae’) may have in supporting missions to the red planet. The current research using these microorganisms in biological life support systems is discussed, with a systematic analysis of their usage in each system conducted. The potential of microalgae to provide astronauts with oxygen, food, bio-polymers and pharmaceuticals is considered. An overview of microalgal experiments in space missions across the last 60 years is presented, and the research exploring the technical challenges of
cultivation on Mars is discussed. From these findings, an argument for culturing microalgae in subterranean bioreactors is proposed. Finally, future synthetic biology approaches for enhancing the cyanobacterial/microalgal role in supporting human deep-space exploration are presented. We show that microalgae hold significant promise for providing solutions to many problems faced by the first Martian settlers, however these can only be realised with significant infrastructure and a reliable power source

Competence is power: how digital influencers impact buying decisions in B2B markets
Get PDFIn B2B markets, vendor companies increasingly rely upon influential individuals in the digital environment to communicate information about their offerings to client organizations. Given the growing B2B digital engagement, cues that help to differentiate highly impactful digital influencers are crucial for vendor companies. Drawing from Stereotype Content Model, we analyze competence and warmth as relevant cues of digital influencers. Employing experimental studies, we examine how competence and warmth influence B2B purchasing managers' evaluation and selection of vendors' solutions. We find that the digital influencers' competence enhances purchasing managers' intention to buy the advocated vendor's offering. When compared with warmth, competence minimizes capability and relational concerns associated with the purchase decision. Further, we show that such effect of competence is prominent when manager-influencer identification is low. Our research advances knowledge on the characteristics of digital influencers that shape B2B purchasing managers' evaluation and selection of vendors. We identify concern-based psychological mechanisms underlying the effect of influencers' characteristics, and related boundary conditions. Our findings provide implications for digital influencers seeking to expand reach in B2B markets, and for vendor companies and marketing agencies in the selection of digital influencers
Housing in the ancient Mediterranean world: material and textual approaches
No full textBook synopsis: One of the greatest benefits of studying the ancient Greek and Roman past is the ability to utilise different forms of evidence, in particular both written and archaeological sources. The contributors to this volume employ this evidence to examine ancient housing, and what might be learned of identities, families, and societies, but they also use it as a methodological locus from which to interrogate the complex relationship between different types of sources. Chapters range from the recreation of the house as it was conceived in Homeric poetry, to the decipherment of a painted Greek lekythos to build up a picture of household activities, to the conjuring of the sensorial experience of a house in Pompeii. Together, they present a rich tapestry which demonstrates what can be gained for our understanding of ancient housing from examining the interplay between the words of ancient texts and the walls of archaeological evidence.
Employs textual and archaeological sources in tandem to explore ancient houses and households
Draws on a broad range of archaeological sites and types of textual evidence
Adopts a range of methodological approaches and critiques these in a historiographical contex
Visual histories of sex: collecting, curating, archiving
No full textIncreased access to visual archives and the proliferation of digitized images related to sexuality have led a growing number of scholars in recent years to place images and visual practices at the center of critical historical inquiries of sexual desire, subjectivity, and embodiment. At the same time, new critical histories of sexual science serve both to expand the temporal and geographical frames for investigating the historical relationships of sex and visual production, and to generate new lines of inquiry and reshape visual studies more broadly. The contributors to this issue invite us to ask: What new questions and challenges for the study of sex and sexual science are posed by critical studies of the visual? How are new visual methodologies that focus on archives changing the contours of historical knowledge about sex and sexuality? What—and where—are new methodologies still needed? “Visual Archives of Sex” aims to illuminate current research that centers visual media in the history of sexuality and that interrogates contemporary historiographies
Does it work? Using a meta-impact score to examine global effects in quasi-experimental intervention studies
Get PDFThe evaluation of applied psychological interventions in the workplace or elsewhere is challenging. Randomisation and matching are difficult to achieve and this often results in substantial heterogeneity within intervention and control groups. As a result, traditional comparison of group means using null hypothesis significance testing may mask effects experienced by some participants. Using longitudinal studies of coaching interventions designed to provide support for dyslexic employees, this study describes and evaluates a different approach using a Meta-Impact score. We offer a conceptual rationale for our method, illustrate how this score is calculated and analysed, and show how it highlights person-specific variations in how participants react and respond to interventions. We argue that Meta-Impact is an incremental supplement to traditional variable-centric group-wise comparisons and can more accurately demonstrate in practice the extent to which an intervention worked. Such methods are needed for applied research, where personalized intervention protocols may require impact analysis for policy, legal and ethical purposes, despite modest sample sizes

How distinctive is the Foreign Language Enjoyment and Foreign Language Classroom Anxiety of Kazakh learners of Turkish?
Get PDFThe present study focuses on foreign language enjoyment (FLE) and foreign language classroom anxiety (FLCA) of 592 learners of Turkish as a foreign language (FL) in Kazakhstan. Mean levels of FLE and FLCA were found to be similar to previous studies in different settings with different target languages. In contrast with previous literature, a weak positive correlation was found between FLE and FLCA and the gender effect went in the opposite direction, with male participants reporting more FLCA than female participants. Multiple regression analyses revealed that FLE and FLCA were more strongly predicted by learners’ attitude toward Turkish and teacher-related variables than by learner-internal variables, confirming previous research outside Kazakhstan. Attitude toward the FL, teacher’s friendliness, strictness and frequency of use of the FL, attitude toward the teacher, participant’s age and FL exam result explained a total of 25% of variance in FLE. Differing slightly from previous studies, FLCA was found to be only weakly predicted (6% of variance) by some learner-internal variables (FL exam result, attitude toward the FL) as well as teacher-centred variables (friendliness, strictness). The findings suggest that variation in FLE and FLCA among Kazakh learners of Turkish is quite similar to that established in other contexts
Introduction to part 4: What is the global in labor markets?
No full textBook synopsis: This volume addresses pertinent questions related to cross-border labor migration and puts forward a “labor market” perspective that goes beyond the national frame of reference prevailing in most of the extant labor market scholarship. In four sections, the volume pulls together a number of key threads: How can we theoretically grasp “global labor markets?” What does existing empirical research reveal about the current state of affairs and the historical development of “global labor markets”, provided that they can even be regarded as “global?” How is the emergence of border-crossing labor markets influenced by existing institutions, international intermediaries and social networks? The editors have crafted a coherent volume that enriches our understanding of both globalization and labor markets
