Outside The Box: What Would a Scientist Do with a Dashboard?

Growing plants on the International Space Station has always been a challenge, but it is research that must continue in order to support long duration missions. A rotating plant system is now undergoing tests at Kennedy Space Center to help mitigate the challenges of getting water and nutrients effectively to plant roots. Traditionally, lab test data is gathered and presented via spreadsheets which can be confusing and cumbersome to deal with. Using SAP BusinessObjects Dashboards (formerly Xcelsius), see how NASA utilizes this visualization software to help monitor and present a clear picture of the research results

Development of an Electrostatic Precipitator to Remove Martian Atmospheric Dust from ISRU Gas Intakes During Planetary Exploration Missions

Manned exploration missions to Mars will need dependable in situ resource utilization (ISRU) for the production of oxygen and other commodities. One of these resources is the Martian atmosphere itself, which is composed of carbon dioxide (95.3%), nitrogen (2.7%), argon (1.6%), oxygen (0.13%), carbon monoxide (0.07%), and water vapor (0.03%), as well as other trace gases. However, the Martian atmosphere also contains relatively large amounts of dust, uploaded by frequent dust devils and high Winds. To make this gas usable for oxygen extraction in specialized chambers requires the removal of most of the dust. An electrostatic precipitator (ESP) system is an obvious choice. But with an atmospheric pressure just one-hundredth of Earth's, electrical breakdown at low voltages makes the implementation of the electrostatic precipitator technology very challenging. Ion mobility, drag forces, dust particle charging, and migration velocity are also affected because the low gas pressure results in molecular mean free paths that are approximately one hundred times longer than those at Earth .atmospheric pressure. We report here on our efforts to develop this technology at the Kennedy Space Center, using gases with approximately the same composition as the Martian atmosphere in a vacuum chamber at 9 mbars, the atmospheric pressure on Mars. We also present I-V curves and large particle charging data for various versions of wire-cylinder and rod-cylinder geometry ESPs. Preliminary results suggest that use of an ESP for dust collection on Mars may be feasible, but further testing with Martian dust simulant is required

Scaling up index insurance for smallholder farmers: Recent evidence and insights

This report explores evidence and insights from five case studies that have made significant recent progress in addressing the challenge of insuring poor smallholder farmers and pastoralists in the developing world. In India, national index insurance programmes have reached over 30 million farmers through a mandatory link with agricultural credit and strong government support. In East Africa (Kenya, Rwanda and Tanzania), the Agriculture and Climate Risk Enterprise (ACRE) has recently scaled to reach nearly 200,000 farmers, bundling index insurance with agricultural credit and farm inputs. ACRE has built on strong partnerships with regional initiatives such as M-PESA mobile banking. In Ethiopia and Senegal, the R4 Rural Resilience Initiative has scaled unsubsidized index insurance to over 20,000 poor smallholder farmers who were previously considered uninsurable, using insurance as an integral part of a comprehensive risk management portfolio. With strong public and private sector support, the Mongolia Index-Based Livestock Insurance Project (IBLIP) insures more than 15,000 nomadic herders and links commercial insurance with a government disaster safety net. Finally, the Index-Based Livestock Insurance (IBLI) project in Kenya and Ethiopia demonstrates innovative approaches to insuring poor nomadic pastoralists in challenging circumstances. A few common features appear to have contributed to recent progress within these case studies: explicitly targeting obstacles to improving farmer income; integration of insurance with other development interventions; giving farmers a voice in the design of products; investing in local capacity; and investing in science-based index development. Evidence from these case studies can inform the ongoing debate about the viability of scaling up index-based insurance for vulnerable smallholder farmers in the developing world. The rapid progress observed in recent years suggests that index insurance has the potential to benefit smallholder farmers at a meaningful scale, and suggests the need to reassess arguments that lack of demand and practical implementation challenges prevent index-based insurance from being a useful tool to reduce rural poverty

Self-organization of the in vitro attached human embryo

Implantation of the blastocyst is a developmental milestone in mammalian embryonic development. At this time, a coordinated program of lineage diversification, cell-fate specification, and morphogenetic movements establishes the generation of extra-embryonic tissues and the embryo proper, and determines the conditions for successful pregnancy and gastrulation. Despite its basic and clinical importance, this process remains mysterious in humans. Here we report the use of a novel in vitro system1,2 to study the post-implantation development of the human embryo. We unveil the self-organizing abilities and autonomy of in vitro attached human embryos. We find human-specific molecular signatures of early cell lineage, timing, and architecture. Embryos display key landmarks of normal development, including epiblast expansion, lineage segregation, bi-laminar disc formation, amniotic and yolk sac cavitation, and trophoblast diversification. Our findings highlight the species-specificity of these developmental events and provide a new understanding of early human embryonic development beyond the blastocyst stage. In addition, our study establishes a new model system relevant to early human pregnancy loss. Finally, our work will also assist in the rational design of differentiation protocols of human embryonic stem cells to specific cell types for disease modelling and cell replacement therapy

Heritage language anxiety and majority language anxiety among Turkish immigrants in the Netherlands

Aims and objectives: This study examines the language anxiety that occurs in immigrants’ daily lives when speaking the heritage language and the majority language, both in their host country and during visits to their home country. It compares the levels of heritage language anxiety and majority language anxiety across three generations of the Turkish immigrant community in the Netherlands and explores the link between immigrants’ language anxiety, and sociobiographical (i.e. generation, gender, education) and language background variables (i.e. age of acquisition, self-perceived proficiency, frequency of language use). Design: A Likert scale-based questionnaire was administered to 116 participants across three generations who reported their language anxiety levels when speaking the heritage language and the majority language in three social contexts (i.e. family, friendship and speaking with native speakers). Findings: Statistical analyses revealed that heritage language anxiety and majority language anxiety were prevalent in immigrants’ daily life, and that levels of both forms of anxiety differed across generations, and in different daily life situations. First- and second-generation immigrants typically experienced majority language anxiety, while second- and predominantly third-generation immigrants suffered from heritage language anxiety. Relationships emerged between language background variables and both forms of anxiety, but only in certain situations. These findings suggest that language background variables on their own may be insufficient to explain immigrant language anxiety in certain social contexts (i.e. within family). Rather than merely language background factors, a variety of other issues within social, cultural and national currents must be considered when examining language anxiety in the immigrant context. Implications: Taking an interdisciplinary approach that combines language contact and foreign language anxiety/second language anxiety research, this study suggests that the concept of foreign language anxiety/second language anxiety should be expanded beyond the confines of the classroom in order to include daily interactions immigrant or minority communities. Originality: This study contributes to the limited body of evidence on the topic of language anxiety in immigrant contexts and presents a new construct ‘majority language anxiety’

Having burned the straw man of Christian spiritual leadership, what can we learn from Jesus about leading ethically?

In considering what it means to lead organizations effectively and ethically the literature comprising spirituality at work (SAW) and spiritual leadership theory (SLT) has become highly influential, especially in the USA. It has also attracted significant criticism. While, in this paper we endorse this critique, we argue that that the strand of literature which purportedly takes a Christian standpoint within the wider SAW school of thought, largely misconstrues and misapplies the teaching of its founder, Jesus. As a result, in dismissing the claims and application of SAW and SLT, there is a real risk that we lose the vital contribution of Christian thought, not least some of the timeless counter-cultural wisdom of Jesus which, we contend, offers a vital foundation to the practice of ethical leadership and business ethics in organisations. In proposing a way forward, two thorny issues which face all leaders are addressed: dealing with ego and closing the gap between what we say and what we do. The more we understand about the dynamics of human nature, the more we learn about the profundity of Jesus’ teachings. We then propose a number of ways in which Jesus-centred ethical leadership can be practised. Each is radical and each implies risk: both the personal risk of inner renewal arising from repentance as a doorway to personal integrity, as well as the risk of opposing unethical practices and promoting the excellence of core practices in the workplace

Editors' introduction: neoliberalism and/as terror

The articles in this special issue are drawn from papers presented at a conference entitled “Neoliberalism and/as Terror”, held at the Nottingham Conference Centre at Nottingham Trent University by the Critical Terrorism Studies BISA Working Group (CSTWG) on 15-16 September 2014. The conference was supported by both a BISA workshop grant and supplementary funds from Nottingham Trent University’s Politics and International Relations Department and the Critical Studies on Terrorism journal. Papers presented at the conference aimed to extend research into the diverse linkages between neoliberalism and terrorism, including but extending beyond the contextualisation of pre-emptive counterterrorism technologies and privatised securities within relevant economic and ideological contexts. Thus, the conference sought also to stimulate research into the ways that neoliberalism could itself be understood as terrorism, asking - amongst other questions - whether populations are themselves terrorised by neoliberal policy. The articles presented in this special issue reflect the conference aims in bringing together research on the neoliberalisation of counterterrorism and on the terror of neoliberalism

Addressing statistical biases in nucleotide-derived protein databases for proteogenomic search strategies

[Image: see text] Proteogenomics has the potential to advance genome annotation through high quality peptide identifications derived from mass spectrometry experiments, which demonstrate a given gene or isoform is expressed and translated at the protein level. This can advance our understanding of genome function, discovering novel genes and gene structure that have not yet been identified or validated. Because of the high-throughput shotgun nature of most proteomics experiments, it is essential to carefully control for false positives and prevent any potential misannotation. A number of statistical procedures to deal with this are in wide use in proteomics, calculating false discovery rate (FDR) and posterior error probability (PEP) values for groups and individual peptide spectrum matches (PSMs). These methods control for multiple testing and exploit decoy databases to estimate statistical significance. Here, we show that database choice has a major effect on these confidence estimates leading to significant differences in the number of PSMs reported. We note that standard target:decoy approaches using six-frame translations of nucleotide sequences, such as assembled transcriptome data, apparently underestimate the confidence assigned to the PSMs. The source of this error stems from the inflated and unusual nature of the six-frame database, where for every target sequence there exists five “incorrect” targets that are unlikely to code for protein. The attendant FDR and PEP estimates lead to fewer accepted PSMs at fixed thresholds, and we show that this effect is a product of the database and statistical modeling and not the search engine. A variety of approaches to limit database size and remove noncoding target sequences are examined and discussed in terms of the altered statistical estimates generated and PSMs reported. These results are of importance to groups carrying out proteogenomics, aiming to maximize the validation and discovery of gene structure in sequenced genomes, while still controlling for false positives
