Published: October 2017

Purpose
Human space exploration to date has been limited to low Earth orbit and the moon. The International Space Station (ISS) provides a unique opportunity for researchers to prove out the technologies that will enable humans to safely live and work in space for longer periods and venture farther into the solar system. The ability to manufacture parts in-space rather than launch them from earth represents a fundamental shift in the current risk and logistics paradigm for human space exploration. The purpose of this mission is to prove out the fused deposition modeling (FDM) process in the microgravity environment, evaluate microgravity effects on the materials manufactured, and provide the first demonstration of on-demand manufacturing for space exploration.

Design/methodology/approach
In 2014, NASA, in cooperation with Made in Space, Inc., launched a 3D printer to the ISS with the goal of evaluating the effect of microgravity on the fused deposition modeling (FDM) process and prove out the technology for use on long duration, long endurance missions where it could leveraged to reduce logistics requirements and enhance crew safety by enabling a rapid response capability. This paper presents the results of testing of the first phase of prints from the technology demonstration mission, where 21 parts where printed on orbit and compared against analogous specimens produced using the printer prior to its launch to ISS.

Findings
Mechanical properties, dimensional variations, structural differences and chemical composition for ground and flight specimens are reported. Hypotheses to explain differences observed in ground and flight prints are also developed. Phase II print operations, which took place in June and July of 2016, and ground-based studies using a printer identical to the hardware on ISS, will serve to answer remaining questions about the phase I data set. Based on Phase I analyses, operating the FDM process in microgravity has no substantive effect on the material produced.

Practical implications
Demonstrates that there is no discernable, engineering significant effect on operation of FDM in microgravity. Implication is that material characterization activities for this application can be ground-based.

Originality/value
Summary of results of testing of parts from the first operation of 3D printing in a microgravity environment.
Modified curing protocol for improved strength of binder-jetted 3D parts
Authors: Watters Matthew P. , Bernhardt Michelle L. 
Published: October 2017

Purpose
This paper aims to present a new curing protocol which improves part strength and provides better repeatability for full-part infiltration by varying binder saturation levels. The fully infiltrated parts were then investigated for their resistance to water.

Design/methodology/approach
Cylinders and spheres generated using various curing procedures and binder saturation levels were subjected to uniaxial compression to determine the effects on the resulting part strength. Additionally, fully cured parts were submerged in water for varying durations to determine the resistance to water. Parts were also weighed prior to and after submersion in water to determine any change in mass.

Findings
Increased part infiltration and improved strength were achieved using a modified curing protocol with a higher oven temperature during curing. Spheres cured following the modified curing protocol resulted in a 300 per cent increase in the average force required to crush spheres. Parts were shown to have repeatable infiltration depths from 8.8 mm to 10.1 mm. Additionally, fully cured parts submerged in water for durations longer than 12 hours developed a reduction in strength.

Originality/value
This study provides key methods to improve part strength and demonstrates a limitation on maximum dimensions of parts which should be considered to behave homogeneously. Parts generated following these guidelines can be effectively used in laboratory and engineering applications where high strength and homogeneous behavior is important.
Attuning to individual work routines and team performance
Authors: de Jong Jeroen P. , Fodor Oana C. 
Published: October 2017

PurposeThe authors first examine the extent to which having an accurate understanding of and anticipate on one another’s work routines (defined as crossattuning) explains additional variance of team performance above and beyond other implicit coordination concepts such as team familiarity and transactive memory. Furthermore, the authors aim to propose that social sensitivity interacts with team size and team longevity in supporting the emergence of cross-attuning.Design/methodology/approachThe authors first use a quasi-experimental design with 35 student-teams in Study 1 to test the discriminant validity of their construct. In Study 2, the authors use a field study with 66 work teams to test their hypotheses.FindingsStudy 1 shows that cross-attuning has a positive effect on team performance and that it explains additional variance above other implicit coordination-concepts. In Study 2, the authors confirm cross-attuning associates with supervisor-rated team performance and find that team social sensitivity is more positively related to cross-attuning in small teams with low longevity and in large teams with high longevity in comparison to large teams with low longevity.Originality/valueThe study of implicit coordination mechanisms in teams has primarily focused on having knowledge about other team members’ expertise and competencies and how teams cope with unexpected events. How teams deal with individual work routines – repetitive work-related behavior that is limited in considering alternative actions and the task environment – have received limited attention, despite the potential of these individual routines to thwart successful team task completion.
Conceptualising a Framework for Effective Performance Measurement in Cultural Precinct Development and Operation
Authors: Schulz Rebekah , Sense Andrew , Pepper Matthew 
Published: October 2017

AbstractThe purpose of this paper is to firstly identify and synthesise critical measurement themes in extant academic literature concerning performance measurement in cultural precincts. Secondly, the paper posits for consideration a holistic and systematic framework (which embraces those themes) for developing appropriate performance measures for cultural precincts. The outcomes in this paper (a) confirm and clarify the complexity of performance measurement needed, (b) furnish a framework for practitioners embarking on the development of such measures, and (c) indicate the conceptual and pragmatic challenges faced in developing and enacting appropriate and meaningful measures for cultural precincts. Consequently, this paper serves as a conceptual positioning paper and a practical embarkation point for practitioners willing to engage with and pursue this phenomenon. Thereby, it endorses more dialogue on and further research and analysis of performance measurement in government operated cultural precincts.
The new subversive geranium: some notes on the management of additional troubles in maximum security prisons
Authors: Liebling Alison , Williams Ryan J. 
Published: October 2017

AbstractIn this paper, we revisit King and McDermott's 1990 article on the social construction of ‘control problem’ prisoners and their management in high security prisons, in the light of our recent research on the location and building of trust in contemporary high security prisons. We examine how religious and race identities are now deeply implicated in the construction of risk, and we describe the procedures for and some of the consequences of managing the new risks of radicalization and extremist violence in prison. The analysis is based on observations and interviews with staff and prisoners in two main and two supplementary maximum‐security prisons in England and Wales.
The class pictures in citizens’ minds
Authors: Robison Joshua , Stubager Rune 
Published: October 2017

AbstractSocial class has traditionally played a key role in explaining social behaviour and cognition. However, recent analyses have been dominated by the view that the relevance of class for behaviour has dwindled in advanced industrial societies. We contest this view by focusing on the subjective components of class consciousness. Using a national survey of Danish citizens, we show that individuals continue to hold meaningful conceptions of classes, to identify with them and, moreover, to perceive substantial levels of differences between them with these latter beliefs being strongly structured by respondent class identification. These results are all the more intriguing because they stem from a high affluence/low inequality national context that should be a particularly good case for failing to find such rich class perceptions.
Identification and characterization of heat shock proteins in a parasitic wasp Chouioia cuneae (Hymenoptera: Eulophidae)

Published: October 2017

AbstractHeat shock proteins (HSPs) are known to be induced in response to various stress factors. Although HSPs have been studied in a number of insects, not much is known about HSPs in the natural enemies of insects, especially parasitoids. In this study, we identified and characterized five full‐length HSP genes (Cchsp40, Cchsp60, Cchsp70, Cchsp83, and Cchsp90) from an endoparasitic chalcid wasp, Chouioia cunea, which parasitizes the fall webworm, Hyphantria cunea pupae, a worldwide pest. The expression of Cchsps in response to temperature, pesticide stresses and UV radiation were also investigated by quantitative real‐time polymerase chain reaction (RT‐qPCR). The results showed that all five Cchsps were induced in response to hot and cold temperatures. Four pesticides induced the abundant expression of Cchsp70, Cchsp83 and Cchsp90 while ultraviolet radiation up‐regulated Cchsp40, Cchsp70, Cchsp83 and Cchsp90. These results indicate the different transcriptional profiles of the five different Cchsps in response to various abiotic stresses. The findings of this study provide insights into the response of C. cunea to abiotic stresses and insight into the use of this parasitoid in biological control strategies.

mvmapper: Interactive spatial mapping of genetic structures
Authors: Dupuis Julian R. , Bremer Forest T. , Jombart Thibaut , Sim Sheina B. , Geib Scott M. 
Published: October 2017

AbstractCharacterizing genetic structure across geographic space is a fundamental challenge in population genetics. Multivariate statistical analyses are powerful tools for summarizing genetic variability, but geographic information and accompanying metadata are not always easily integrated into these methods in a user‐friendly fashion. Here, we present a deployable Python‐based web‐tool, mvmapper, for visualizing and exploring results of multivariate analyses in geographic space. This tool can be used to map results of virtually any multivariate analysis of georeferenced data, and routines for exporting results from a number of standard methods have been integrated in the R package adegenet, including principal components analysis (PCA), spatial PCA, discriminant analysis of principal components, principal coordinates analysis, nonmetric dimensional scaling and correspondence analysis. mvmapper's greatest strength is facilitating dynamic and interactive exploration of the statistical and geographic frameworks side by side, a task that is difficult and time‐consuming with currently available tools. Source code and deployment instructions, as well as a link to a hosted instance of mvmapper, can be found at https://popphylotools.github.io/mvMapper/.
International Legal Encounters with Democracy
Authors: Charlesworth Hilary 
Published: October 2017

AbstractThe language of democracy has become common in international law, the legal system that regulates relations between nation states. This interest in democracy has however largely ignored democracy at the international level and focused instead on national democratic standards. In this paper, I start by sketching the threadbare debates about democracy beyond political borders in international law and then turn to the way that international institutions have developed this concept, particularly in the peace and state‐building boom associated with the end of the Cold War. The two contexts for democracy have taken different directions. In the case of democracy at the international level, the discussion has become polarised between global North and South, with democracy being promoted by the South as an omnibus agenda to remedy economic and political inequalities. In the case of democracies within states, international lawyers have taken democracy to have a fixed form, associated with specific institutional practices and structures, limiting its capacity for transformation.
Patterns of substance use and mortality risk in a cohort of ‘hard‐to‐reach’ polysubstance users
Authors: Gjersing Linn , Bretteville‐Jensen Anne Line 
Published: October 2017

AbstractAimsTo examine the mortality risk in a cohort of ‘hard‐to‐reach’ polysubstance users and its putative associations with substance use. Specifically, we estimated all‐cause mortality risk as a function of individual substance use indicators, and then as a function of their complex, ‘real‐life’ patterns as identified through latent class analysis (LCA).DesignProspective cohort study among street‐ and low‐threshold service‐recruited polysubstance users included between September and November 2013 and followed through the National Cause of Death Registry until 31 October 2015.SettingSeven Norwegian cities.ParticipantsA total of 884 users of illegal opioids and/or stimulants. Of these, 357 were in opioid substitution treatment (OST) at the time of inclusion. Forty‐four participants died during follow‐up.MeasurementsPrimary outcome: all‐cause mortality risk. Unadjusted and adjusted Cox proportional hazard (PH) regression models (covariates: male, age, homelessness/shelter use, overdose experience, OST status, years of injecting, individual substance use indicators, city, use patterns). LCA models estimated separately for those in and those not in OST due to measurement invariance.FindingsThe crude mortality rate was 2.52 per 100 person‐years. Standardized mortality ratio was 26.11 [95% confidence interval (CI) = 10.06–54.87] for women and 10.71 (95% CI = 6.39–16.81) for men. No single drug use indicator, such as ‘heroin injection’ or ‘number of drugs used’, was associated with the mortality risk. However, meaningful use patterns were identified; three OST and non‐OST patterns each. The non‐OST patterns ‘polysubstance injectors’ [hazard ratio (HR) = 3.45, 95% CI = 0.98–12.14] and ‘low frequent injectors’ (HR = 3.17, CI = 1.05–9.56) were associated significantly with the mortality risk even when adjusted for other known risk factors.ConclusionsIn a Norwegian prospective cohort study, ‘hard‐to‐reach’ polysubstance users had a more than 10 times higher mortality risk than the general population. Mortality risk was not a function of any single drug use indicator, but two distinct combinations of substances, frequencies and routes of administration were associated with the mortality risk.
Trends in age of smoking initiation in the Netherlands: a shift towards older ages?
Authors: Nuyts Paulien A. W. , Kuipers Mirte A. G. , Willemsen Marc C. , Kunst Anton E. 
Published: October 2017

AbstractBackground and aimAs smoking initiation generally occurs in adolescence, smoking prevention is targeted primarily at young adolescents (aged below 16 years). We hypothesize that, with the adoption of increasingly stronger youth access laws, a shift in the age of smoking initiation may have occurred.DesignRepeated cross‐sectional survey.SettingThe Netherlands.ParticipantsA total of 13 163 respondents born between 1980 and 1995.MeasurementsIn the 2010–15 National Health Survey we measured retrospectively self‐reported initiation rates per year of age by birth cohort (1980–83, 1984–87, 1988–91, 1992–95). Logistic regression analyses were performed to assess differences between cohorts, per sex and educational level.FindingsOf those who started smoking, 67.2% initiated smoking between 12 and 16 years of age. Contrary to our hypothesis, no shift in initiation towards higher ages was observed. The peak age of initiation was 16 years for all cohorts. Initiation at ages 17–21 was lower in younger birth cohorts than in older birth cohorts [e.g. cohort 1993–95 versus 1980–83: odds ratio (OR) for initiating at 19–21 years = 0.45, 95% confidence interval (CI) = 0.31–0.64]. Trends in age of initiation were similar for males and females. Initiation at ages 15–17 decreased across cohorts for respondents in higher education levels, but not for those in lower education levels.ConclusionsIn the Netherlands, the peak age of smoking initiation did not shift throughour subsequent cohorts born between 1980 and 1995, suggesting that young adolescents remain the main target group for smoking initiation prevention policies.
Impulsivity predicts poorer improvement in quality of life during early treatment for people with methamphetamine dependence

Published: October 2017

AbstractBackground and aimsMethamphetamine dependence is associated with heightened impulsivity and diminished quality of life, but the link between impulsivity and changes in quality of life during treatment has not been examined. We aimed to investigate how different elements of impulsivity predict change in quality of life in the 6 weeks after engaging in treatment.DesignLongitudinal, observational cohort study.SettingPublic and private detoxification and rehabilitation facilities in metropolitan Melbourne, Australia.ParticipantsOne hundred and eight individuals with methamphetamine dependence (81 male) tested within 3 weeks of commencing treatment; 80 (74%) were followed‐up at 6 weeks.MeasurementsThe Continuous Performance Test‐2 measured impulsive action (cognitive and motor impulsivity); the Delay Discounting Task measured impulsive choice. Quality of life was measured with the World Health Organization Quality of Life Scale—Brief, which includes social, psychological, physical and environment domains. Control variables included age, gender, estimated IQ, depression severity score, methamphetamine dependence severity score, cannabis dependence severity score and treatment modality.FindingsWe found that all three forms of impulsivity were significant predictors of change in the social domain: motor impulsivity (β = −0.54, P = 0.013), cognitive impulsivity (β = −0.46, P = 0.029) and impulsive choice (β = −0.26, P = 0.019). Change in the psychological domain was predicted significantly by motor impulsivity (β = −0.45, P = 0.046). Control variables of age and depression were associated significantly with changes in the physical domain.ConclusionsIn Australian methamphetamine‐dependent individuals, elevated impulsivity predicts lower improvement of social and psychological quality of life in the first 6–9 weeks of treatment.

Published: October 2017

AbstractAimsTo estimate and test the difference in rates of violent and non‐violent crime during medicated and non‐medicated methadone treatment episodes.Design, Setting and ParticipantsThe study involved linkage of population level administrative data (health and justice) for all individuals (n = 14 530) in British Columbia, Canada with a history of conviction and who filled a methadone prescription between 1 January 1998 and 31 March 2015. Methadone maintenance treatment was the primary independent variable and was treated as a time‐varying exposure. Each participant's follow‐up (mean: 8 years) was divided into medicated (methadone was dispensed) and non‐medicated (methadone was not dispensed) periods with mean durations of 3.3 and 4.6 years, respectively.MeasurementsSocio‐demographics of participants were examined along with the main outcomes of violent and non‐violent offences.FindingsDuring the first 2 years of treatment (≤ 2.0 years), periods in which methadone was dispensed were associated with a 33% lower rate of violent crime [0.67 adjusted hazard ratio (AHR), 95% confidence intervals (CI) = 0.59, 0.76] and a 35% lower rate of non‐violent crime (0.65 AHR, 95% CI = 0.62, 0.69) compared with non‐medicated periods. This equates to a risk difference of 3.6 (95% CI = 2.6, 4.4) and 37.2 (95% CI = 33.0, 40.4) fewer violent and non‐violent offences per 100 person‐years, respectively. Significant but smaller protective effects of dispensed methadone were observed across longer treatment intervals (2.0 to ≤ 5.0 years, 5.0 to ≤ 10.0 years).ConclusionsAmong a cohort of Canadian offenders, rates of violent and non‐violent offending were lower during periods when individuals were dispensed methadone compared with periods in which they were not dispensed methadone.

AbstractWe studied the kinetics of C1‐inhibitor (C1‐INH) and other complement parameters in a self‐limited edematous attack (EA) in a patient with hereditary angioedema due to C1‐INH deficiency to better understand the pathomechanism of the evolution, course, and complete resolution of EAs. C1‐INH concentration and functional activity (C1‐INHc+f), C1(q,r,s), C3, C4, C3a, C4a, C5a, and SC5b‐9 levels were measured in blood samples obtained during the 96‐hour observation period. The highest C1‐INHc+f, C4, and C1(q,r,s) levels were measured at baseline, and their continuous decrease was observed during the entire observation period. C4 depletion started at prodromal phase, and C4 was lowest after the maximum severity peak. Compared to baseline, C4a level was four times higher 7 hours before the onset of the attack. C1‐INH did not increase after resolution of the attack suggesting that factors other than C1‐INH may be important in this process. C4a may be a useful biomarker for the prediction of EAs.
