Reclaiming constructivism: towards an interpretive reading of the ‘Social Construction Framework’
Authors: Barbehön Marlon 
Published: February 2020

AbstractThe ‘Social Construction Framework’ which addresses the relationship between policy design and the construction of target groups is one of the central approaches within the field of policy theories. Yet, despite its name, the approach builds on several naturalist premises, and its analytical components are informed by principles rooted in positivist methodologies. Against this background, this article conducts a thorough critique of the framework’s constructivist shortcomings, and it develops a strictly constructivist and interpretive reading of its core arguments. The analytical value is substantiated by presenting original empirical research on the meaning of the ‘middle class’ in German welfare policy. We will show that, firstly, group construction is not only a matter of positive or negative evaluation, but more fundamentally an act of boundary-drawing, with differently constructed middle classes enabling different welfare policies. Secondly, we will show that target group constructions are always entangled with the construction of the group’s outside, leading to the stabilisation and legitimisation of hierarchies between the middle class and ‘the others’ in society. Thirdly, we demonstrate that the power of a target group is also a matter of social construction, with the middle class obtaining its hegemonic position from an order of knowledge that equates the middle with ‘the normal’ and ‘the common good’. Based on these insights, the article raises a more general plea against the translation of constructivism into a middle-range theory of the policy process and instead emphasises the ontological and epistemological distinctiveness of strict constructivism and interpretive methodologies.

Abstract
Purpose
Mild cognitive impairment (MCI) is a widespread phenomenon, especially affecting older individuals. We will analyze in how far MCI affects different facets of quality of life (QOL).

Methods
We used a sample of 903 participants (110 with MCI) from the fifth follow-up of the German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe), a prospective longitudinal study, to analyze the effects of MCI on different facets of the WHOQOL-OLD. We controlled for age, gender, marital status, education, living situation, daily living skills, and the ability to walk, see, and hear.

Results
Univariate analyses showed that individuals with MCI exhibited lower QOL with regard to the facets autonomy; past, present, and future activities; social participation; and intimacy, but less fears related to death and dying. No significant difference was shown with regard to the facet sensory abilities. In multivariate analyses controlling for age, gender, marital status, education, living situation, daily living skills, and the ability to walk, see and hear, MCI-status was significantly associated with QOL in the facet autonomy.

Conclusion
Effects of MCI go beyond cognition and significantly impact the lives of those affected. Further research and practice will benefit from utilizing specific facets of QOL rather than a total score.
SWEclat: a frequent itemset mining algorithm over streaming data using Spark Streaming
Authors: Xiao Wen , Hu Juan 
Published: February 2020

AbstractFinding frequent itemsets in a continuous streaming data is an important data mining task which is widely used in network monitoring, Internet of Things data analysis and so on. In the era of big data, it is necessary to develop a distributed frequent itemset mining algorithm to meet the needs of massive streaming data processing. Apache Spark is a unified analytic engine for massive data processing which has been successfully used in many data mining fields. In this paper, we propose a distributed algorithm for mining frequent itemsets over massive streaming data named SWEclat. The algorithm uses sliding window to process streaming data and uses vertical data structure to store the dataset in the sliding window. This algorithm is implemented by Apache Spark and uses Spark RDD to store streaming data and dataset in vertical data format, so as to divide these RDDs into partitions for distributed processing. Experimental results show that SWEclat algorithm has good acceleration, parallel scalability and load balancing.

Published: February 2020

AbstractSA508 grade 3 steel is widely used in the manufacture of large-scale forged components for nuclear reactor applications. Numerical models have already been established to simulate industrial forging process of grade 3 steel; however, limited information is available on the microstructural evolution of this steel during hot forging operation. This work focuses on the flow behavior and related microstructural evolution in grade 3 steel with detailed analysis on the interfacial friction, texture and hardness evolution. Uniaxial hot compression tests were conducted over a range of test temperatures (880-1130 °C) and true strain rates (0.001-1/s), representative of the industrial hot forging conditions. Two different deformation mechanisms, MDRX at the lowest forging temperature and DRV along with DRX at the highest forging temperature, were observed showing marked impact on the final microstructure and hardness. A random fiber-type weak deformation texture was observed irrespective of the test temperatures and strain rates used. The microstructural changes from the as-received to the various deformed conditions were quantified. The quantitative data are the key to obtain accurate parameters for DRV and DRX processes that affect the accuracy of the mathematical models.
Swyneshed, Aristotle and the Rule of Contradictory Pairs
Authors: Read Stephen 
Published: February 2020

AbstractRoger Swyneshed, in his treatise on insolubles (logical paradoxes), dating from the early 1330s, drew three notorious corollaries from his solution. The third states that there is a contradictory pair of propositions both of which are false. This appears to contradict what Whitaker, in his iconoclastic reading of Aristotle’s De Interpretatione, dubbed “The Rule of Contradictory Pairs” (RCP), which requires that in every such pair, one must be true and the other false. Whitaker argued that, immediately after defining the notion of a contradictory pair, in which one statement affirms what the other denies of the same thing, Aristotle himself gave counterexamples to the rule. This gives some credence to Swyneshed’s claim that his solution to the logical paradoxes is not contrary to Aristotle’s teaching, as many of Swyneshed’s contemporaries claimed. Insolubles are false, he said, because they falsify themselves; and their contradictories are false because they falsely deny that the insoluble itself is false. Swyneshed’s solution depends crucially on the revision he makes to the acount of truth and falsehood, brought out in his first thesis: that a false proposition can signify as it is, or as Paul of Venice, who took up and developed Swyneshed’s solution some sixty years later, puts it, a false proposition can have a true significate. Swyneshed gave a further counterexample to (RCP) when he claimed that some insolubles, like future contingents, are neither true nor false. Dialetheism, the contemporary claim that some propositions are both true and false, is wedded to the Rule, and in consequence divorces denial from the assertion of the contradictory negation. Consequently, Swyneshed’s logical heresy is very different from that found in dialetheism.
Good gamers, good managers? A proof-of-concept study with Sid Meier’s Civilization

Published: February 2020

AbstractHuman resource professionals increasingly enhance their assessment tools with game elements—a process typically referred to as “gamification”—to make them more interesting and engaging for candidates, and they design and use “serious games” that can support skill assessment and development. However, commercial, off-the-shelf video games are not or are only rarely used to screen or test candidates, even though there is increasing evidence that they are indicative of various skills that are professionally valuable. Using the strategy game Civilization, this proof-of-concept study explores if strategy video games are indicative of managerial skills and, if so, of what managerial skills. Under controlled laboratory conditions, we asked forty business students to play the Civilization game and to participate in a series of assessment exercises. We find that students who had high scores in the game had better skills related to problem-solving and organizing and planning than the students who had low scores. In addition, a preliminary analysis of in-game data, including players’ interactions and chat messages, suggests that strategy games such as Civilization may be used for more precise and holistic “stealth assessments,” including personality assessments.
Contrasting color loss and restoration in survivors of the 2014–2017 coral bleaching event in the Turks and Caicos Islands

Published: February 2020

AbstractCoral cover throughout the Caribbean region has declined by approximately 80% since the 1970s (Gardner et al. in Ecology 86(1):174–184, 2005) attributed to a combination of environmental and anthropogenic factors, including ocean acidification, rising sea surface temperatures, increased susceptibility to disease, as well as increased frequency and strength of storms, development stress, and increased sediment and nutrient loads. Three Global Bleaching Events (GBE) coincide directly with El Niño warming phases in El Niño-Southern Oscillation cycle (1997–1998, 2009–2010, and 2014–2017). This study focuses the effects of anomalously high sea surface temperatures on Turks and Caicos Islands coral taxa during the 2014–2017 GBE. Interannual and interspecific variability in coral health offshore of South Caicos Island were evaluated between 2012 and 2018 using the CoralWatch citizen science Coral Health Chart method along belt transects at four dive survey sites. The study includes 104 site surveys conducted from 15 October 2012 to 18 July 2018. Coral health was assessed for the 35 principal coral taxa and 5646 individual corals. Data indicates that all coral taxa at the study sites were resilient to the maximum regional thermal stress during the 2014–2017 GBE, with boulder-type corals showing no significant bleaching as a result of the peak thermal stress in late 2015 and plate-type corals responding with a significant (p < 0.05) bleaching signal (i.e., coral color reductions), rebounding to pre-GBE pigmentations within months of the anomalously-high thermal stress. Boulder coral types were significantly healthier in 2017 than in 2014 when using coral color as a health diagnostic.
Arsenic-Bearing Serpentine-Group Minerals: Mineral Synthesis with Insights for the Arsenic Cycle

Published: February 2020

AbstractWhen present at elevated levels in drinking water, arsenic is toxic, and magnesian clays are gaining recognition as a source of elevated arsenic in groundwater. In the crust and upper mantle of Earth, arsenic incorporation into clay minerals is influenced by geochemical conditions associated with hydrothermal fluids and metamorphic processes (e.g. serpentinization), meaning that As is a useful tracer of fluid-flow in the deep Earth. To improve understanding of arsenic speciation in groundwater, sediments, soils, and hydrothermal-metamorphic systems, the present study examined arsenic incorporation into magnesian clays by synthesis of serpentine minerals (200oC, 10 d) with varied concentrations of Si, Al, As5+, and As3+. The synthesis experiments produced two distinct crystal types, tubular and platy serpentines, each with 10–15% randomly interstratified talc layers. X-ray absorption spectroscopy indicated that As5+ and As3+ occurred in the tetrahedral sheet. Single-crystal analysis revealed that tubular crystals contained up to 1 wt.% arsenic [Mg2.8(Si1.8As0.2)O5(OH)4] (mean 0.2 wt.% As). The mean composition of platy, high-Al crystals is (Mg1.8Al0.7)(Si2.0)O5(OH)4, and that of platy, medium-Al crystals with As3+ is (Mg2.07Al0.52) (Si1.97As3+0.03)O5(OH)4. Charge, geometry, and radius of tetrahedral AsO43– oxyanions are similar to tetrahedral SiO44–, and this facilitates fixation of As5+ into the tetrahedral sheet of clay minerals. The geometry and size of the larger As3+ in tetrahedral sites (as a pyramidal AsO33– oxyanion) may limit incorporation relative to As5+. Arsenic-bearing Mg clays crystallize in alkaline environments where AsO43– or AsO33– are the dominant As species and where high pH accompanies crystallization of serpentine, talc, chlorite, or Mg-smectite. The presence of tetrahedral As in these clays raises the possibility of tetrahedral As in other Mg clays (e.g. sepiolite or kerolite) as well.
Evaluating barley landraces collected in North Africa and the Middle East for powdery mildew infection at seedling and adult plant stages

AbstractBarley (Hordeum vulgare L.) is one of the most widely grown cereal crops. Numerous pathogens impair the amount and quality of the grain yield. Blumeria graminis f. sp. hordei (Bgh) is a fungal pathogen causing powdery mildew, a widespread and economically important foliar disease. Since there is a limited number of known resistance genes, efforts of scientists and breeders are focused on searching for new sources of resistance. Barley landraces are a known, but still underexploited source of diversity. A set of 79 barley landraces collected in North Africa and the Middle East was tested against powdery mildew at seedling and adult plant stages. Under a controlled environment, 50% of accessions showed resistance conditioned by major genes. Among them, seven accessions showed broad resistance to Bgh isolates that were virulent to most of the known resistance genes. The field experiments carried out under natural infection over several years indicated all accessions as potential sources for resistance breeding. Twelve landraces were found to be medium resistant or resistant during all six seasons. This report relates to barley landraces as a promising source of potentially novel resistance to powdery mildew.

ABSTRACTObjective:The aim of this study is to determine the response of home-based primary care programs to the fall 2017 Atlantic hurricane season.Methods:This study examines the experiences of 9 Veterans Health Administration (VHA) Home-Based Primary Care (HBPC) programs in their responses to Hurricanes Harvey, Irma, and Maria. Thirty-four phone interviews with HBPC leadership and staff were conducted from April to July 2018.Results:The total census of impacted HBPC programs was 3118. No program reported loss of life due to these hurricanes. Early preparedness was key to an effective program response. Response included prompt tracking of the patients. In the most affected areas, respondents noted limited resources to support basic patient needs.Conclusions:Medically complex patients served by programs such as the VHA’s HBPC program represent a subset of the population, yet they have an outsized impact on health care resources that could be exacerbated by inadequate disaster preparedness. HBPC programs serve a unique role in supporting the “older old.” They are tasked with supporting disaster preparedness activities of patients. Understanding what is involved in actualizing their requirements shows communities how to effectively engage with these programs.
Campylobacteriosis associated with the consumption of unpasteurised milk: findings from a sentinel surveillance site

AbstractCampylobacteriosis is the most common notifiable disease in New Zealand. While the risk of campylobacteriosis has been found to be strongly associated with the consumption of undercooked poultry, other risk factors include rainwater-sourced drinking water, contact with animals and consumption of raw dairy products. Despite this, there has been little investigation of raw milk as a risk factor for campylobacteriosis. Recent increases in demand for untreated or ‘raw’ milk have also raised concerns that this exposure may become a more important source of disease in the future. This study describes the cases of notified campylobacteriosis from a sentinel surveillance site. Previously collected data from notified cases of raw milk-associated campylobacteriosis were examined and compared with campylobacteriosis cases who did not report raw milk consumption. Raw milk campylobacteriosis cases differed from non-raw milk cases on comparison of age and occupation demographics, with raw milk cases more likely to be younger and categorised as children or students for occupation. Raw milk cases were more likely to be associated with outbreaks than non-raw milk cases. Study-suggested motivations for raw milk consumption (health reasons, natural product, produced on farm, inexpensive or to support locals) were not strongly supported by cases. More information about the raw milk consumption habits of New Zealanders would be helpful to better understand the risks of this disease, especially with respect to increased disease risk observed in younger people. Further discussion with raw milk consumers around their motivations may also be useful to find common ground between public health concerns and consumer preferences as efforts continue to manage this ongoing public health issue.

AbstractWe implanted two sinus Superflex DS© stents in a systemic non-stenotic arterial duct of a newborn with hypoplastic left heart syndrome. Forty-eight hours later an important collapse of the stent was detected and treated with a balloon expandable stent. Sinus Superflex DS© has been specifically designed for systemic ducts. This complication generates doubts about its radial force in this scenario.
Going Dutch? Lessons from the Outcome-Based Political Science Curriculum in the Netherlands
Authors: Breuning Marijke 
Published: February 2020

ABSTRACTDutch political science curricula integrate the acquisition of knowledge of the discipline and transferable skills. This makes it an interesting case for US political science education, especially in light of Wahlke’s (1991) recommendations for a structured political science curriculum that incorporates skills training in addition to knowledge of the field. Although some of Wahlke’s recommendations were widely adopted, US political science curricula remain relatively loosely structured and often do not explicitly focus on transferable skills.This article argues that the Dutch example may help US programs revisit how to best achieve learning outcomes that allow students to acquire both knowledge and transferable skills. This is not an argument for “going Dutch” wholesale; instead, the article suggests modest modifications to US political science curricula.
Diet quality, nutrient intakes and biochemical status of New Zealand women of childbearing age according to alcohol consumption patterns

Published: February 2020

AbstractObjective:To investigate associations between alcohol consumption patterns and diet quality, nutrient intakes and biochemical profile of women of childbearing age.Design:Nutrient intake data from 24 h diet recalls, alcohol consumption data and diet quality from the Dietary Habits Questionnaire, and biochemical analyses from the cross-sectional 2008/09 Adult Nutrition Survey in New Zealand.Setting:New Zealand households.Participants:New Zealand women aged 18–45 years (n1124).Results:All analyses were completed using Stata and survey weights were used to allow for the complex survey design to produce population estimates. Multinomial logistic regression models were used to examine the associations between drinking patterns and the variables of interest, with ‘infrequent moderate/light’ drinkers being the reference category. The findings indicate that alcohol-consuming women of childbearing age tend to replace food energy with alcohol energy (P= 0·022). ‘More frequent heavy’ and ‘more frequent moderate/light’ drinkers had higher intakes of total, mono- and polyunsaturated fats with the latter group also consuming higher levels of saturated fats (P< 0·05). Women who were ‘infrequent moderate/light’ drinkers had relatively better diet quality, nutrient intakes and adequate biochemical status in comparison to other drinkers and abstainers. ‘Infrequent heavy’ drinkers, who were predominantly younger in age, had lower serum vitamin B12levels (P= 0·01) with a higher proportion of women in this category having below-recommended levels of serum folate (P< 0·05).Conclusions:Alcohol consumption, especially heavy drinking patterns, may compromise nutritional status of women of childbearing age.
Delineating Environmental Stresses to Primary Production of U.S. Forests From Tree Rings: Effects of Climate Seasonality, Soil, and Topography

Published: February 2020

AbstractPrimary production is the entry point of energy and carbon into ecosystems, but modeling responses of primary production to “environmental stress” (i.e., reductions of primary production from nonoptimal environmental conditions) remains a key challenge and source of uncertainty in our understanding of Earth's carbon cycle. Here we develop an approach for estimating annual “environmental stress” from tree rings based on the proportion of the optimal diameter growth rate (from species‐specific allometric equations) that is realized in a given year. We assessed climatic, topographic, and soil drivers of environmental stress, as well as their interactions, using both empirical model experiments and linear mixed effect models. Climate gradients and interannual climate variability dominated spatial and temporal variability of environmental stress in much of the western United States, where the tree‐ring environmental stress index was positively correlated with antecedent climatic water balance (precipitation minus potential evapotranspiration) and negatively correlated with temperature and vapor pressure deficit. Excluding topographic and soil information from empirical models reduced their ability to capture spatial gradients in environmental stress, particularly in the eastern United States, where growth was not as strongly limited by climate. Mean climate conditions and topographic characteristics had significant interaction effects with the climatic water balance, indicating an increasing importance of winter moisture for warmer and drier sites and as elevation and topographic wetness index increased. These results suggest that including effects of antecedent climate (particularly in dry regions) and site topographic and soil characteristics could improve parameterization of environmental stress effects in primary production models.
