AbstractWhile the control of knowledge is becoming the dominant means by which economic, political, and social control is exerted globally, the mechanisms through which this is happening—including intellectual property rights, state and commercial surveillance, digitisation and datafication, and a nearly ubiquitous internet mediating human interactions—are often examined separately instead of as part of a larger phenomenon of knowledge governance. This edited volume brings experts in these areas from across the social sciences to explore these areas as forms of knowledge governance, by adopting the understudied (at least from a knowledge-governance perspective) work of the late International Political Economy scholar Susan Strange, notably her concept of a knowledge structure. In this chapter, we present an introduction to and critique of Strange’s theory of the knowledge structure and offer an overview of this volume’s chapters.

Published: June 2019

AbstractMathematical models can take very different forms and very different levels of complexity. A systematic way to postulate, calibrate and validate, as provided by systems theory, can therefore be very helpful. In this chapter, dynamic systems modelling of aquaponic (AP) systems, from a systems theoretical perspective, is considered and demonstrated to each of the subsystems of the AP system, such as fish tanks, anaerobic digester and hydroponic (HP) greenhouse. It further shows the links between the subsystems, so that in principle a complete AP systems model can be built and integrated into daily practice with respect to management and control of AP systems. The main challenge is to choose an appropriate model complexity that meets the experimental data for estimation of parameters and states and allows us to answer questions related to the modelling objective, such as simulation, experiment design, prediction and control.

Published: June 2019

AbstractHydroponics is a method to grow crops without soil, and as such, these systems are added to aquaculture components to create aquaponics systems. Thus, together with the recirculating aquaculture system (RAS), hydroponic production forms a key part of the aqua-agricultural system of aquaponics. Many different existing hydroponic technologies can be applied when designing aquaponics systems. This depends on the environmental and financial circumstances, the type of crop that is cultivated and the available space. This chapter provides an overview of different hydroponic types, including substrates, nutrients and nutrient solutions, and disinfection methods of the recirculating nutrient solutions.

AbstractPancreatic β cell damage is one of the crucial factors responsible for the development of type 2 diabetes mellitus (T2DM). Previous studies have suggested that puerarin (PR) could regulate the activities of the mitochondrial respiratory chain complex in diabetic nephropathy (DN); however, whether PR can inhibit pancreatic β-cell apoptosis in T2DM remains to be elucidated. In the present study, T2DM mice induced by high-fat diet and streptozotocin (STZ) injection were used as a working model to investigate the mechanism of PR on pancreatic β cell apoptosis. The results showed that PR decreased the serum fasting blood glucose (FBG), total cholesterol (TC), triglyceride (TG) and low-density lipoprotein (LDL) levels but significantly increased the fasting blood insulin (FINS) and high-density lipoprotein (HDL) levels. Furthermore, decreased caspase-3, 8, 9 and apoptosis-inducing factor (AIF) proteins in the pancreas were detected by Western blot analysis. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling (TUNEL) staining demonstrated that the pancreatic β cell apoptosis was inhibited by PR. Furthermore, PR improved the histopathological changes in pancreatic tissue in T2DM mice. Collectively, the data show that PR can protect the β cells from apoptotic death in a mouse model of T2DM through regulating the expression of apoptosis-related protein-AIF and caspase family proteins.
Modeling and simulation of weld solidification cracking part II
Authors: Draxler J. , Edberg J. , Andersson J. , Lindgren L.-E. 
Published: June 2019

AbstractSeveral advanced alloy systems are susceptible to weld solidification cracking. One example is nickel-based superalloys, which are commonly used in critical applications such as aerospace engines and nuclear power plants. Weld solidification cracking is often expensive to repair, and if not repaired, can lead to catastrophic failure. This study, presented in three papers, presents an approach for simulating weld solidification cracking applicable to large-scale components. The results from finite element simulation of welding are post-processed and combined with models of metallurgy, as well as the behavior of the liquid film between the grain boundaries, in order to estimate the risk of crack initiation. The first paper in this study describes the crack criterion for crack initiation in a grain boundary liquid film. The second paper describes the model for computing the pressure and the thickness of the grain boundary liquid film, which are required to evaluate the crack criterion in paper 1. The third and final paper describes the application of the model to Varestraint tests of Alloy 718. The derived model can fairly well predict crack locations, crack orientations, and crack widths for the Varestraint tests. The importance of liquid permeability and strain localization for the predicted crack susceptibility in Varestraint tests is shown.

Published: June 2019

AbstractIntroductionThe implementation of spatial‐covariance [18F]fluorodeoxyglucose positron emission tomography–based disease‐related metabolic brain patterns as biomarkers has been hampered by intercenter imaging differences. Within the scope of the JPND‐PETMETPAT working group, we illustrate the impact of these differences on Parkinson's disease–related pattern (PDRP) expression scores.MethodsFive healthy controls, 5 patients with idiopathic rapid eye movement sleep behavior disorder, and 5 patients with Parkinson's disease were scanned on one positron emission tomography/computed tomography system with multiple image reconstructions. In addition, one Hoffman 3D Brain Phantom was scanned on several positron emission tomography/computed tomography systems using various reconstructions. Effects of image contrast on PDRP scores were also examined.ResultsHuman and phantom raw PDRP scores were systematically influenced by scanner and reconstruction effects. PDRP scores correlated inversely to image contrast. A Gaussian spatial filter reduced contrast while decreasing intercenter score differences.DiscussionImage contrast should be considered in harmonization efforts. A Gaussian filter may reduce noise and intercenter effects without sacrificing sensitivity. Phantom measurements will be important for correcting PDRP score offsets.

AbstractBackground:Several observational studies have investigated the association of insomnia with psychiatric disorders. Such studies yielded mixed results, and whether these associations are causal remains unclear. Thus, we aimed to identify the causal relationships between insomnia and five major psychiatric disorders.Methods:The analysis was implemented with six genome-wide association studies; one for insomnia and five for psychiatric disorders (attention-deficit/hyperactivity disorder, autism spectrum disorder, major depressive disorder, schizophrenia, and bipolar disorder). A heterogeneity in dependent instrument (HEIDI) approach was used to remove the pleiotropic instruments, Mendelian randomization (MR)-Egger regression was adopted to test the validity of the screened instruments, and bidirectional generalized summary data-based MR was performed to estimate the causal relationships between insomnia and these major psychiatric disorders.Results:We observed significant causal effects of insomnia on the risk of autism spectrum disorder and bipolar disorder, with odds ratios of 1.739 (95% confidence interval: 1.217–2.486, p = 0.002) and 1.786 (95% confidence interval: 1.396–2.285, p = 4.02 × 10−6), respectively. There was no convincing evidence of reverse causality for insomnia with these two disorders (p = 0.945 and 0.546, respectively). When insomnia was considered as either the exposure or outcome variable, causal estimates for the remaining three psychiatric disorders were not significant.Conclusions:Our results suggest a causal role of insomnia in autism spectrum disorder and bipolar disorder. Future disease models should include insomnia as a factor for these two disorders to develop effective interventions. More detailed mechanism studies may also be inspired by this causal inference.

AbstractPrior research on Hodgins’ (2008) typology of offenders with schizophrenia spectrum disorders (SSD) has revealed inconsistencies in the number of subgroups and the operationalization of the concept. This study addressed these inconsistencies by applying latent class analysis (LCA) based on the most frequently explored variables in prior research. This novel case-centred methodology identified similarities and differences between the subjects contained in the sample instead of the variables explored. The LCA was performed on 71 variables taken from data on a previously unstudied sample of 370 case histories of offenders with SSD in a centre for inpatient forensic therapies in Switzerland. Results were compared with Hodgins’ theoretically postulated patient typologies and confirm three separate homogeneous classes of schizophrenic delinquents. Previous inconsistencies and differences in operationalizations of the typology of offenders with SDD to be found in the literature are discussed.

ABSTRACTObjective:Using validated psychological assessment instruments, this study examined the psychological distress associated with potential language barriers experienced by over 135 000 Puerto Rican residents who either temporarily or permanently migrated to the continental United States with the landfall of Hurricane Maria in 2017.Methods:Participants were Puerto Rican residents (n = 107) who remained in Puerto Rico (control) or left the island for at least 3 months because of Hurricane Maria (migrants). Participants completed an online survey in their preferred language (Spanish or English), which assessed self-reported English language proficiency, Kessler Psychological Distress Scale (K6), Posttraumatic Stress Disorder Checklist for DSM 5, Patient Health Questionnaire 9-item depression scale, and the Generalized Anxiety Disorder 7-item scale. It was hypothesized that migrants with lower self-reported English proficiency would have comparatively higher indices of post-disaster distress than those with a higher proficiency.Results:Dividing the migrant group by preferred language for questionnaire completion, the Fisher’s exact test showed significant differences in prevalence of severe mental distress, as defined by K6 scores above 13, between the Spanish-preferring migrants (30.4%), English-preferring migrants (0%), and controls (9.6%).Conclusion:Our results support a possible correlation between decreased language proficiency in post-disaster migrants and a higher risk factor for severe mental distress.

ABSTRACTObjectives:Hurricane Harvey left a path of destruction in its wake, resulting in over 100 deaths and damaging critical infrastructure. During a disaster, public health surveillance is necessary to track emerging illnesses and injuries, identify at-risk populations, and assess the effectiveness of response efforts. The Centers for Disease Control and Prevention (CDC) and American Red Cross collaborate on shelter surveillance to monitor the health of the sheltered population and help guide response efforts.Methods:We analyzed data collected from 24 Red Cross shelters between August 25, 2017, and September 14, 2017. We described the aggregate morbidity data collected during Harvey compared with previous hurricanes (Gustav, Ike, and Sandy).Results:Over one-third (38%) of reasons for visit were for health care maintenance; 33% for acute illnesses, which includes respiratory conditions, gastrointestinal symptoms, and pain; 19% for exacerbation of chronic disease; 7% for mental health; and 4% for injury. The Red Cross treated 41% of clients within the shelters; however, reporting of disposition was often missed. These results are comparable to previous hurricanes.Conclusion:The capacity of Red Cross shelter staff to address the acute health needs of shelter residents is a critical resource for local public health agencies overwhelmed by the disaster. However, there remains room for improvement because reporting remained inconsistent.

Published: June 2019

ObjectivesAn Early Intervention in Psychosis (EIP) programme aims to engage patients in early assessment and phase-specific interventions which are the key elements of the Irish National Clinical Programme for psychosis. This study aims to describe and review the EIP programme offered by Cork’s North Lee Mental Health Services over a 5-year period.MethodsA retrospective descriptive study design was adopted to describe and review the EIP programme, patient demographics and treatments offered in the service over a 5-year period.ResultsA total of 139 patients were accepted into the programme over the 5-year period. The mean age of onset was 30 years (median = 28, SD = 9.9), and the mean duration of untreated psychosis was 8 months (median = 2.5, SD = 15.3). Two-thirds of patients were single on initial assessment, had a history of substance misuse and were unemployed. The majority of the cohort engaged with the keyworkers and occupational therapy but did not complete the full psychological or family programmes offered. Hospital admission was required for 12% of the cohort.ConclusionsPatients experiencing their first episode of psychosis can successfully be treated in the community with appropriate professional and family support. However, deficiencies were noted in physical health monitoring, as well as in the availability and engagement with family and psychological therapies. Properly resourced early interventions in psychosis teams are necessary to deliver services at internationally recognised standards.
Does infusion time affect the retention of parenteral trace elements?
Authors: Ferrie Suzie 
Published: June 2019

AbstractWhen readymade parenteral nutrition in multi-chamber bags is supplied without vitamins and minerals, these have to be added or given separately. Separate rapid infusion has logistical advantages but has been claimed to saturate tissue mechanisms, potentially increasing urine micronutrient losses. The present study compared urinary losses after fast (1 h) v. slow (10 h) trace elements infusion. The study enrolled thirty-nine consecutive patients who were starting parenteral nutrition postoperatively. One day’s dose of a complete intravenous micronutrient product was infused over 1 h and over 10 h, in random order, with a washout day after each infusion day. Urinary Zn, Mn, Se, Cr, Cu and Fe losses were measured by 24-h urine collection, recorded for each infusion day and subsequent washout day. For Zn, a dose of 100 μmol was given, and total urinary loss over the next 2 d was mean 40·6 (sd 23·8) μmol after the fast (1 h) infusion v. 33·4 (sd 25·4) μmol after the slow (10 h) infusion, that is, 7 % more of the 1-d dose was lost after fast infusion (P = 0·01). For Mn, after a dose of 1000 nmol, losses were 9·8 (sd 23·9) nmol after the fast infusion v. 22·1 (sd 47·2) nmol after the slow infusion, that is, 1 % more of the 1-d dose was lost after slow infusion (P = 0·04). There were no other significant differences: after 1 μmol Se, the losses were 1·5 (sd 0·6) μmol fast v. 1·3 (sd 0·5) μmol slow; after 200 nmol Cr, 257 (sd 92) μmol fast v. 246 (sd 107) nmol slow; after 8 μmol Cu, 1·6 (sd 1·4) μmol fast v. 1·5 (sd 1·3) μmol slow; and after 20 μmol Fe, 0·6 (sd 1·1) μmol fast v. 0·8 (sd 1·6) μmol slow (P > 0·05 for all). Overall, trace element retention appears to be minimally affected by infusion time.
Preservation amenity, research laboratory, or mineral reserve? International perspectives on the values of Antarctica
Authors: Tin Tina , Peden John , O’Reilly Jessica , Bastmeijer Kees , Maher Patrick T. 
Published: June 2019

AbstractInspired by notions of interest of humankind and intergenerational equity, we explored Antarctic perceptions of a subset of future generations—university students. Students at three universities in Canada, the Netherlands, and the USA were surveyed to determine the relationships between nationality, academic major, opinions on values of Antarctica, and support for a range of human activities in Antarctica (n = 618). Logistic regression was used to model the relationship of these variables with support for designation of Antarctica as a wilderness reserve, construction of new research stations, and mining. Compared with business and economics majors, biological sciences and natural resources/conservation majors were more likely to support wilderness designation and less likely to support mineral resource development. Nationality was not significantly associated with support for construction of new research stations and mineral resource development. Opinions on the value of Antarctica and support for activities also exhibited significant influences on dependent variables. Consistent with earlier studies of Antarctic scientists, personnel, tourists, and other members of the general public, university students valued Antarctica as one of the world’s last great wildernesses (66%), an important component of the Earth’s climate system (66%), and a science laboratory for the benefit of mankind (62%).
Forensic patients in state psychiatric hospitals: 1999–2016
Authors: Wik Amanda , Hollen Vera , Fisher William H. 
Published: June 2019

Introduction.In recent years mental health officials have reported a rise in the number of forensic patients present within their state psychiatric hospitals and the adverse impacts that these trends had on their hospitals. To date there have been no large-scale national studies conducted to determine if these trends are specific only to a few states or representative of a more global trend. The purpose of this study was to investigate these reported trends and their national prevalence.Methods.The forensic directors of each state behavioral health agency (including the District of Columbia) were sent an Excel spreadsheet that had two components: a questionnaire and data tables with information collected between 1996 and 2014 from the State Profiling System maintained by the National Association of State Mental Health Program Directors Research Institute. They were asked to verify and update these data and respond to the questionnaire.Results.Responses showed a 76% increase nationally in the number of forensic patients in state psychiatric hospitals between 1999 and 2014. The largest increase was for individuals who were court-committed after being found incompetent to stand trial and in need of inpatient restoration services.Discussion.The data reviewed here indicate that increases in forensic referrals to state psychiatric hospitals, while not uniform across all states, are nonetheless substantial.Conclusion.More research is needed to determine whether this multi-state trend is merely a coincidence of differing local factors occurring in many states, or a product of larger systemic factors affecting mental health agencies and the courts.
‘Nutrition is out of our control’: soldiers’ perceptions of their local food environment

Published: June 2019

AbstractObjective:To explore the perceptions of soldiers participating in a US Army Office of The Surgeon General’s worksite health promotion programme (WHPP) on the local food environment within their campus-style workplace.Design:Focus groups were conducted to evaluate the perceived effectiveness of the WHPP implementation. Further exploration of focus group data through thematic analysis focused on perceived contributions of the military campus-style food environment to soldiers’ nutrition behaviours.Setting:Three US Army installations located in the continental USA.Participants:Active duty soldiers (n 366) participating in one of the fifty-eight focus groups.Results:Soldiers shared a common belief of self-discipline and personal responsibility as the foothold to nutrition behaviour change. Soldiers described aspects of the military campus-style food environment as factors impeding achievement of optimal nutrition. Collectively, soldiers perceived the proximity and density of fast-food restaurants, lack of healthy alternatives on the installation and the cost of healthy food as inhibitors to choosing healthy foods. Overwhelmingly, soldiers also perceived time constraints as a factor contributing to unhealthy food choices.Conclusions:Although nutrition behaviour is individually driven, soldiers perceived the military campus-style food environment inhibits healthy decision making. Nutrition programming in military WHPP must integrate food environment changes to improve soldiers’ nutrition behaviour outcomes. Applicable to the military, food choice behaviour studies suggest environmental changes must be appealing to young adults. Considerations for environmental changes should include an increased portion size for healthy options, broadened use of soldiers’ daily food allowances on local produce and increased availability of grab-and-go options.
