Priorities of training of digital personnel for industry 4.0: social competencies vs technical competencies
Authors: Popkova Elena G. , Zmiyak Kristina V. 
Published: October 2019

Purpose
The purpose of this paper is to determine the priorities of formation of competencies during training of digital personnel for industry 4.0.

Design/methodology/approach
The author performs two experiments for determining the scenario according to which industry 4.0 develops and will develop: the first experiment is aimed at determining the influence of the number of robots at unemployment level in 2019 and 2022 with the help of regression and correlation analysis (regression curves are built). The second experiment is connected to evaluation of the ratio of the number of robots to the number of population in 2019 and 2022. The research objects are countries with the highest number of robots in the world – i.e. with the highest level of development of industry 4.0; the information and empirical basis is materials of the International Federation of Robotics and the International Monetary Fund for 2019 and their forecasts for 2022.

Findings
The results of the performed experiments showed that in 2019 and 2022 the level of robotization of socio-economic systems of the countries of the world will be very low, and robotization will not cause growth of unemployment. Based on this, it is concluded that industry 4.0 will be developing according to the scenario of moderate automatization and robotization with preservation of domination of human labor in most business processes and spheres of economy. Communications with people will constitute the basis of the activities of digital personnel, and social competencies (with obvious significance of technical competencies) will be of top priority for them.

Originality/value
It is substantiated that technical competencies, with their large importance, will move to the background, while the key task will be society’s adaptation to the new technological mode and making social competencies the highest priority. The social and technical competencies of digital personnel in view of the performed tasks for industry 4.0 are determined.

Published: October 2019

Purpose
This paper aims to analyze experimentally and numerically the effect of the nozzle temperature and feed rates on the dimensions of the fused deposition modeling (FDM) polymer parts.

Design/methodology/approach
In total, 30 strips per sample were printed with the same width as the nozzle diameter. The strips were printed with one vertical movement of the nozzle head. The width of the strips was measured with a caliper at five locations. A linear regression model was created based on the experimental data to understand the correlation between the strip width deviation and the parameters of interest. Numerical simulations were performed to predict the swell of the polymer exiting the nozzle using finite element method combined with level set method. The experimental results were then used to validate the models.

Findings
The average accuracy of polylactic acid (PLA) samples was better than that of acrylonitrile butadiene styrene (ABS) samples. The average strip width had a tendency to increase with increasing temperature for PLA samples, whereas ABS samples showed mixed behavior. The strip width decreased with increasing feed rate for most cases. The measurement positions had a major effect on strip width when compared to nozzle temperature and feed rate. The numerical model predictions were in good agreement with the experimental data. A few discrepancies were observed at high feed rates and nozzle temperatures.

Originality/value
This study will contribute to gaps in knowledge regarding the effect of processing conditions on dimensional accuracy of FDM-printed parts. The developed numerical model can be efficiently used to predict the dimensional accuracy of FDM-printed parts.

Authors: Guo Zhi , Shan Zhongde , Liu Feng , Du Dong , Zhao Mengmeng 
Published: October 2019

PurposeIn this paper, the effects of the adhesive and curing agent contents on the tensile strength, bending strength, gas evolution and gas permeability of three-dimensional printed sand molds are studied. A strength model of the three-dimensional printed sand molds is proposed. The multi-material composite sand mold forming test is carried out. In addition, the mesostructure of the sand mold is studied.Design/methodology/approachThe performances of three-dimensional printed sand mold such as tensile strength, bending strength, gas evolution and gas permeability are studied using the standard test methods. The mesostructure of the sand mold is studied by digital core technology.FindingsA sand mold strength model based on the resin adhesive content, curing agent content and sand mold compactness are obtained. Two types of multi-material composite three-dimensional printed sand molds are proposed. An increase in the curing agent content in the sand mold widens the mesoscopic characteristic size distribution of the sand mold, and large-sized mesostructures appear, resulting in a decrease in the sand mold bearing capacity.Practical implicationsProcess parameters that affect the performance of three-dimensional printed sand mold are revealed. The sand mold bearing curve provides a reference for the ultimate design of three-dimensional printed sand mold.Originality/valueThe paper deals with experimental work on the performance and mesostructure of multi-material composite three-dimensional printed sand mold with different contents of adhesive and curing agent. That gives a perspective on future designs of sand mold based on these principles.

Authors: Singh Swati , Vanka Sita 
Published: October 2019

Purpose
The purpose of this paper is to highlight the importance of the employee voice in the present era. This paper discusses the drawbacks of not attending to employee voice, benefits of listening to it and strategies, as well as the methods of capturing the voice of employees.

Design/methodology/approach
The paper uses illustration to explain how Cisco used employee voice to revamp its HR.

Findings
The research on this area indicates that although listening to employee voice is beneficial, most organizations ignore it. The findings suggest that the voice of employee cannot be ignored in the technology-led era, as employees have many platforms to raise their concerns. Additionally, ignoring their voice can be perilous. Attending to employee voice brings many advantages, and thus it should be prioritized, promoted and practiced. The paper carries implications for HR managers, business leaders and researchers in this field.

Originality/value
This paper uniquely discusses the significance of employee voice in the present era. It also presents the strategies and methods to capture employee voice. Furthermore, it demonstrates the benefits of attending to employee voice with the help of an illustration.

Published: October 2019

PurposeThe purpose of this paper is to present an overview of the history, current status and possible future directions for intellectual disability (ID) policy and practice in South Africa (SA).Design/methodology/approachThe paper was developed by academics and practitioners in the field of ID in SA. A review of the literature, accompanied by a joint writing and discussion process was carried out to identify critical issues in the development of ID services, specifically facing the challenge of moving from racially based provision towards equitable services for all citizens with ID.FindingsProgressive policy has replaced practices of scientific racism which were previously used to support the establishment of white supremacism. This positive move is still in process and has not resulted in the immediate establishment of human rights. A vibrant civil society is engaging with this task currently.Research limitations/implicationsThe findings point to the need for a human rights approach that takes into account the postcolonial context of SA.Practical implicationsThere is a need for continued advocacy that is inclusive of people with ID and their families.Social implicationsContinuing engagement between government and civil society is recommended to ensure the achievement of human rights for citizens with ID.Originality/valueThis paper is of value to ID researchers and practitioners from the global South as it describes a non-western context that might have resonance with other low and middle income countries.
Do benefits of seed dispersal and caching by scatterhoarders outweigh the costs of predation? An example with oaks and yellow‐necked mice
Authors: Bogdziewicz Michał , Crone Elizabeth E. , Zwolak Rafał 
Published: October 2019

Abstract

Numerous interactions between plants and animals vary in their outcome between antagonism and mutualism. Interactions between plants and scatter‐hoarding animals provide a prime example of this phenomenon. Scatterhoarders consume large quantities of seeds (potentially reducing plant establishment), yet also disperse seeds and bury them in shallow caches (potentially improving recruitment). Despite intense work on mechanisms that cause these interactions to shift along an antagonism–mutualism continuum, it remains difficult to quantify their final outcomes.

We demonstrate how readily available field data can be used to reach this goal, with interactions between rodents and two oaks species (sessile oak Quercus petraea, and red oak Q. rubra) as an empirical example. Our approach consists of quantifying the net outcome of the interaction through collecting data on different vital rates (e.g. probability that cached seeds survive to germination, probability of seedling recruitment with and without rodents; near and far from conspecific trees; with and without seed pilferage) and assembling them in a simple mathematical model.

We found that during the period of the study, interactions between scatter‐hoarding rodents and both focal oaks were antagonistic. Even though caching increased the likelihood of seedling establishment, this effect was not strong enough to compensate for the costs of seed predation. Furthermore, there was no evidence that the short‐distance transportation that is usually provided by small mammals benefited early oak recruitment.

Synthesis. Our empirical results demonstrated that certain common assumptions – that caching by rodents invariably benefits plant recruitment; that improved seedling establishment after seed burial is sufficient to make plant–scatterhoarder interactions mutualistic; that transportation away from maternal plants is highly beneficial—do not always hold and should be tested rather than taken for granted.
How people respond to military crisis: Exploring the role of military affiliation, gender and political ideology
Authors: Park Sejin 
Published: October 2019

AbstractThe current research analyses people's trust in the military during military crisis. Also, this research explores whether the three demographic factors that were known to influence people's perceptions of the military (i.e. military identity, gender and political affiliation) played roles in military crisis. The results indicated that, compared to pre‐crisis situation, both civilian and military publics showed lower scores on their trust in the military after a military crisis than before. Also, the three factors were identified as the indicators of military crisis responsibility. Theoretical and practical implications of the findings are discussed.

Published: October 2019

AbstractObjectiveTo assess whether an electronic health record (EHR) portal to enable health information exchange (HIE) between a hospital and three skilled nursing facilities (SNFs) reduced likelihood of patient readmission.Setting/DataSecondary data; all discharges from a large academic medical center to SNFs between July 2013 and March 2017, combined with portal usage records from SNFs with HIE access.DesignWe use difference‐in‐differences to determine whether portal implementation reduced likelihood of readmission over time for patients discharged to HIE‐enabled SNFs, relative to those discharged to nonenabled facilities. Additional descriptive analyses of audit log data characterize portal use within enabled facilities.Data CollectionEncounter‐level clinical EHR data were merged with EHR audit log data that captured portal usage in the timeframe associated with a patient transition from hospital to SNF.Principal FindingsDeclines in likelihood of 30‐day readmission were not significantly different for patients in HIE‐enabled vs control SNFs (diff‐in‐diff = 0.022; P = .431). We observe similar null effects with shorter readmission windows. The portal was used for 46 percent of discharges, with significant usage pattern variation within/across facilities.ConclusionsImplementation of a hospital‐SNF EHR portal did not reduce readmissions from enabled SNFs. Emergent HIE use cases need to be better defined and leveraged for design and implementation that generates value in the context of postacute transitions.

Authors: Boudreaux Michel , Noon James M. , Fried Brett , Pascale Joanne 
Published: October 2019

AbstractObjectiveTo measure discordance between aggregate estimates of means‐tested coverage from the American Community Survey (ACS) and administrative counts and examine the association of discordance with ACA Medicaid expansion.Data Sources2010‐2016 ACS and counts of Medicaid and Children's Health Insurance Program enrollment from the Centers for Medicare & Medicaid Services.Study DesignState‐by‐year counts of means‐tested coverage from the ACS were compared to administrative counts using percentage differences. Discordance was compared for states that did and did not adopt expansion using difference‐in‐differences. We then contrasted the effect of expansion on means‐tested coverage estimated from the ACS with results from administrative data.Data Collection/ExtractionSurvey and administrative data.Principal FindingsOne year before expansion there was a 0.8 and 4 percent overcount in expansion and nonexpansion states, respectively. By 2016, there was a 10.64 percent undercount in expansion states vs a 0.02 percent undercount in nonexpansion states. The ACS suggests that expansion increased means‐tested coverage in the full population by three percentage points, relative to five percentage points suggested by administrative records.ConclusionsDiscordance between the ACS and administrative records has increased over time. The ACS underestimates the impact of Medicaid expansion, relative to administrative counts.
Diet quality is more strongly related to food skills rather than cooking skills confidence: Results from a national cross‐sectional survey
Authors: Lavelle Fiona , Bucher Tamara , Dean Moira , Brown Hannah M. , Rollo Megan E. , Collins Clare E. 
Published: October 2019

AbstractAimWhile diet quality has declined globally, the promotion of cooking skills as a potential target to counter the decline has been proposed. The aim of the current study was to investigate the relationship between food and cooking skills and diet quality in Australian adults.MethodsA sample of 910 Australian adults completed an online cross‐sectional survey to evaluate their level of cooking and food skills confidence, food related psychological variables, diet quality using the Australian Recommended Food Score (ARFS) and sociodemographic characteristics. Analysis of variance with post hoc analysis, Pearson's correlations and hierarchical multiple regressions were conducted using IBM SPSS V25, with statistical significance set at P < .05.ResultsOlder respondents and females reported higher levels of both cooking and food skills confidence compared to younger and male participants, all P < .001. Cooking and food skills confidence scores were highly correlated (r = .70, P < .001), but weakly correlated with ARFS (r = .22, P < .001; r = .31, P < .001, respectively). Participants with higher diet quality scores had greater cooking and food skills confidence and they consumed less takeaway food (P < .001 and P = .006, respectively). Sixteen percent of the variance in ARFS was accounted for, with age, sex, food creativity and food skills confidence contributing the most variability.ConclusionsStrategies to improve food skills confidence could potentially enhance diet quality and variety to a greater degree than focusing on cooking skills alone. However, development of both skills sets should be encouraged within education programs and targeted to differing aspects of diet quality. Tailoring interventions to specific population groups with low confidence in their skills, including younger adults and males, may facilitate individuals in making healthy food choices.

Authors: Broome Kieran , Swanepoel Libby 
Published: October 2019

AbstractAimsResearch involvement is fundamental to the practice of dietetics. The present study aims to benchmark the research track record of Australian dietetic academics, and to provide insight into how research productivity informs the level of appointment of academics across the career pathway.MethodsAustralian dietetic faculty websites and corresponding Scopus database profiles were used to support a bibliographic analysis of Australian dietetic academics’ research track record. Current research productivity in relation to academic attributes, level of appointment, and institutional characteristics were explored.ResultsIn Australia, dietetic academic level of appointment is logarithmically related to number of publications and relatively consistent across regions and university networks.ConclusionsBenchmarking provides universities with guidance regarding the performance to expect from academics at each academic level as well as feedback regarding recruitment and promotion practices. The present study provides an important benchmark for Australian dietetic academics and offers implications for individual academics and university management.
Ecophysiological traits of invasive alien Acacia cyclops compared to co‐occuring native species in Strandveld vegetation of the Cape Floristic Region
Authors: Morris Taryn L. , Barger Nichole N. , Cramer Michael D. 
Published: October 2019

AbstractTree invasions of Mediterranean‐climate ecosystems pose a significant threat to both biodiversity and functioning, by excluding native species, altering soil nutrient status and depleting water resources. In order to attain greater relative biomass associated with successful invasion in these characteristically resource‐poor environments, invasive species must have novel traits that enable better acquisition (e.g. deep roots) or exploitation of different resources (e.g. N2 fixation) and/or more efficient use of available resources than native species. We compared the ecophysiological and morphological traits of three abundant native species to those of the invasive Australian tree species, Acacia cyclops. This species is widely invasive in the Mediterranean‐climate coastal vegetation of South Africa that includes the Strandveld vegetation type. A. cyclops had 30–50% greater foliar N concentrations (P < 0.001) in comparison with the native species and lower foliar δ15N values that may indicate N2 fixation. Additionally, A. cyclops maintained higher photosynthetic rates over the dry summer season (ca. 15 μmol m−2 s−1) than the native species. These higher photosynthetic rates may result from sustained access to water due to deeper rooting abilities as indicated by the more negative δD values (P < 0.001) of A. cyclops (−43‰) in comparison with the some native species (−29 to −37‰). Acacia cyclops did not, however, exhibit greater water use efficiencies or photosynthetic nitrogen use efficiencies (P > 0.05) compared to native species. Invasiveness of A. cyclops into this resource‐limited Mediterranean‐climate ecosystem appears to be supported by greater resource acquisition, possibly partially through N2 fixation and greater rooting depth, rather than greater resource use efficiency or conservation.
Determination of the international maize price: What is the growing role of Brazil and Ukraine?
Authors: Arnade Carlos , Hoffman Linwood 
Published: October 2019

AbstractThis paper examines the relationships among maize prices for four countries to determine if newly emerging exporters, Brazil and Ukraine, influence the international price of maize. Our work focuses on each market's participation in the price discovery process rather than trying to determine a price leader. We find that the United States plays the largest role in price discovery, followed by Argentina, Brazil, and Ukraine. We also search for export thresholds and find that Ukraine's contribution to price discovery rises slightly when an export threshold of 2.3 million tons is reached. No export thresholds were found for Brazil. Export thresholds for Argentina were found but only have a minor impact on price relationships. We also found that price relationships vary considerably across seasons of the year.
Distribution of neuronal structures immunoreactive for parvalbumin in the midcingulate cortex of the rabbit
Authors: Uddin Mohi , Shibata Hideshi 
Published: October 2019

AbstractThe rabbit midcingulate cortex that enclosed four cortical areas was immunohistochemically studied using a calcium‐binding protein, parvalbumin, as a neurochemical marker. The distribution of parvalbumin‐immunopositive somata and fibres was similar across all four areas, where they were present mainly in layers 2/3 and 5. However, there were a slightly greater number of the immunopositive structures in the two ventral areas than the two dorsal areas. Similarity in the distribution of parvalbumin‐immunopositive structures across the four areas suggests that neurons expressing parvalbumin may be involved in similar functions across the constituent areas of the rabbit midcingulate cortex.
