AbstractOrganic sorbents alter physicochemical soil properties and mitigate heavy metal (HM) bioavailability. However, some sorbents are labile and, therefore, introduce the risk of HM release into soil after mineralisation. Before field application, new stable organic sorbents such as woodchip biochar (BIO) and brown coal waste (BCW) need to be tested and compared with standard organic amendments like farmyard manure (FYM). An incubated pot experiment was conducted to investigate the efficacy of FYM, BIO and BCW (added to soil in pots at 5 and 10% w/w) to alter soil physicochemical properties and mitigate bioavailability of Cd, Pb and Zn spiked in treatments at different doses (in mg kg−1); 0 (not spiked), 1 (1 Cd, 70 Pb, 100 Zn) and 2 (3 Cd, 500 Pb, 700 Zn), and incubated for 9 weeks. At the end of the experiment, the EDTA-extractable HM fractions, pH, cation exchange capacity (CEC) and specific surface area (SSA, to check trends) were determined in all treated soils. Results showed that FYM, BCW and BIO generally improved all soil properties (except reduced pH from BCW and apparent SSA reduction from FYM) and accounted for respective maximum abatements of Cd (50.2, 69.9 and 25.5%), Pb (34.2, 64.3 and 17.4%) and Zn (14.9, 17.7 and 11.8%) bioavailability in soil. FYM and BCW were more effective at 10% w/w especially in the low contaminated soil, whereas the highest efficacy for BIO was at 5% w/w and in the high contaminated soil. The efficacies of sorption by the organic sorbents varied for different HMs and were in the orders: BCW > FYM > BIO for Cd, FYM > BCW > BIO for Pb and BIO > BCW > FYM for Zn. Soil pH and CEC were strongly correlated with HM bioavailability in all treatments and implied that immobilisation of HMs occurred via complex formation, ion exchange and pH-dependent specific adsorption. All three sorbents were beneficial as soil amendments, and in terms of HM mitigation, BCW had the highest efficacy, followed by FYM and then BIO. Considering the documented high soil stability of BCW and BIO, these results are promising for further trialling at field scale.

Published: October 2020

AbstractThis work evaluates the release of phosphorus contained in the digestate from the anaerobic digestion of pig manure, through an acidification process. The objective of this acidification is to increase the amount of phosphorus available in the digestate liquid fraction and, subsequently, recover this element by chemical precipitation in the form of struvite or calcium phosphate. Two digestate samples (one fresh and one old) were studied and treated by adding various amounts of sulphuric acid to the different digestate fractions (raw digestate, solid fraction and liquid fraction). For the raw digestate, phosphorus releases higher than 95% were obtained for pH 4.0. In the last part of the experiment, the influence of acid pre-treatment on the reaction yield of phosphorus precipitation, in the form of struvite or calcium phosphate, was determined. Improvements in reaction yield were obtained up to 15% for struvite and 80% for calcium phosphate, increasing also in 7.5 times the amount of phosphorus available in the digestate liquid fraction, for both cases.

Published: October 2020

AbstractTraumatic brain injury (TBI) was shown to lead to the development of cerebral microbleeds (CMBs), which are associated with long term cognitive decline and gait disturbances in patients. The elderly is one of the most vulnerable parts of the population to suffer TBI. Importantly, ageing is known to exacerbate microvascular fragility and to promote the formation of CMBs. In this overview, the effect of ageing is discussed on the development and characteristics of TBI-related CMBs, with special emphasis on CMBs associated with mild TBI. Four cases of TBI-related CMBs are described to illustrate the concept that ageing exacerbates the deleterious microvascular effects of TBI and that similar brain trauma may induce more CMBs in old patients than in young ones. Recommendations are made for future prospective studies to establish the mechanistic effects of ageing on the formation of CMBs after TBI, and to determine long-term consequences of CMBs on clinically relevant outcome measures including cognitive performance, gait and balance function.
The Zygote Argument Is Still Invalid: So What?
Authors: Mickelson Kristin M. 
Published: October 2020

AbstractIn “The Zygote Argument is Invalid: Now What?”, Kristin Mickelson argues that Alfred Mele’s original Zygote Argument is invalid: its two premises tell us merely that the truth of determinism is (perhaps spuriously) correlated with the absence of free human agents, but the argument nonetheless concludes with a specific explanation for that correlation, namely that deterministic laws (of the sort described by determinism) preclude—rule out, destroy, undermine, make impossible, rob us of—free will. In a recent essay, Gabriel De Marco grants that the original Zygote Argument is invalid for the reasons that Mickelson has identified, and claims that he has developed two new solutions to her invalidity objection. In this essay, I argue that both of his proposed solutions are nonstarters, the first fails as a “rescue” because it simply restates an extant solution in new jargon and the second fails because it consists in another invalid variant of the original Zygote Argument.
What is Criminal Rehabilitation?
Authors: Forsberg Lisa , Douglas Thomas 
Published: October 2020

AbstractIt is often said that the institutions of criminal justice ought or—perhaps more often—ought not to rehabilitate criminal offenders. But the term ‘criminal rehabilitation’ is often used without being explicitly defined, and in ways that are consistent with widely divergent conceptions. In this paper, we present a taxonomy that distinguishes, and explains the relationships between, different conceptions of criminal rehabilitation. Our taxonomy distinguishes conceptions of criminal rehabilitation on the basis of (i) the aims or ends of the putatively rehabilitative measure, and (ii) the means that may be used to achieve the intended end. We also explore some of the implications of each conception, some of the payoffs of a taxonomy of the kind we offer, and some areas for future work.
Management control packages in family businesses: a configurational approach
Authors: Einhorn Stefanie , Heinicke Xaver , Guenther Thomas W. 
Published: October 2020

AbstractThis study uses survey data from top managers to explore how operational (e.g., cost types and cost center accounting) and strategically oriented (e.g., strategic and business planning) management accounting (MA) practices, diagnostic and interactive use of performance measures, and cultural controls are combined (management control package) to achieve high firm performance in family businesses (FBs). In previous research, such management control (MC) packages have received limited attention even though they offer an opportunity to reveal more information on the adoption of MA practices, use of performance measures, and MCs in FBs than analyses of individual control mechanisms. We chose a qualitative comparative analysis (QCA) because this method allows for explicitly addressing the three major challenges of configurational theory: asymmetry, conjunctional causation, and equifinality. By applying QCA, our study identifies six equifinal MC packages (i.e., different configurations of MA practices, types of use, and cultural controls with similar associations with firm performance) and, thus, provides an exploratory approach to describe more complex MA and MC designs that are empirically observable. By further analyzing these MC packages with additional information on the intensity of competition, the intensity of attention focusing, the interpretation of information by top management, and the organizational culture, this study extends the existing literature on FBs. The key finding of our analysis is that, regardless of their business environment, successful FBs place a very strong emphasis on cultural controls and/or have a high degree of interactive use of performance measures to steer their business.

Abstract
Summary
The purpose was to determine if increasing serum 25(OH)D and calcium in postmenopausal women increased skeletal muscle size, strength, balance, and functional task performance while decreasing muscle fatigue. PCSA of the vastus lateralis increased and ascent of stairs time decreased after 6 months of increased serum 25(OH)D.

Purpose
The Institute of Medicine recommends ≥ 20 ng/ml of serum 25-hydroxyvitamin D [25(OH)D] for bone and overall health. Serum 25(OH)D levels have been associated with physical performance, postural sway, and falls. The purpose of this study was to determine if increasing postmenopausal women’s serum 25(OH)D levels from 20–30 ng/ml to 40–50 ng/ml improved skeletal muscle size, strength, balance, and functional performance while decreasing skeletal muscle fatigue.

Methods
Twenty-six post-menopausal women (60–85 years old) with baseline serum 25(OH)D levels between 20 and 30 ng/ml were recruited. Oral over-the-counter (OTC) vitamin D3 and calcium citrate were prescribed to increase subjects’ serum 25(OH)D to levels between 40 and 50 ng/ml, serum calcium levels above 9.2 mg/dl, and PTH levels below 60 pg/ml, which were confirmed at 6 and 12 weeks. Outcome measures assessed at baseline and 6 months included muscle physiological cross-sectional area (PCSA), muscle strength, postural balance, time to perform functional tasks, and muscle fatigue. Repeated measures comparisons between baseline and follow-up were performed.

Results
Nineteen subjects completed the study. One individual could not afford the time commitment for the repeated measures. Three individuals did not take their vitamin D as recommended. Two subjects were lost to follow-up (lack of interest), and one did not achieve targeted serum 25(OH)D. Vastus lateralis PCSA increased (p = 0.007) and ascent of stair time decreased (p = 0.042) after 6 months of increasing serum 25(OH)D levels from 20–30 ng/ml to 40–50 ng/ml. Isometric strength was unchanged. Anterior-posterior center of pressure (COP) excursion and COP path length decreased (p < 0.1) albeit non-significantly, suggesting balance may improve from increased serum 25(OH)D and calcium citrate levels.

Conclusions
Several measures of muscle structure and function were sensitive to elevated serum 25(OH)D and calcium levels indicating that further investigation of this phenomenon in post-menopausal women is warranted.
Effect of Tempering on the Bainitic Microstructure Evolution Correlated with the Hardness in a Low-Alloy Medium-Carbon Steel

Published: October 2020

Abstract
A low-alloy medium-carbon bainitic steel was isothermally tempered at 300 °C for up to 24 hours which led to a significant hardness decrease. In order to explain the decreasing hardness, extensive microstructural characterization using scanning and transmission electron microscopy, X-ray diffraction, and atom probe tomography was conducted. The experimental work was further supplemented by thermodynamic and kinetic simulations. It is found that the main underlying reason for the hardness reduction during tempering is related to dislocation annihilation, possibly also with corresponding changes in Cottrell atmospheres. On the other hand, cementite precipitate size, effective grain size of the bainite, and retained austenite fraction appear unchanged over the whole tempering cycle.

Published: October 2020

AbstractNeural stem cells (NSCs) have been recently identified in the inferior colliculus (IC). These cells are of particular interest, as no casual therapeutic options for impaired neural structures exist. This research project aims to evaluate the neurogenic potential in the rat IC from early postnatal days until adulthood. The IC of rats from postnatal day 6 up to 48 was examined by neurosphere assays and histological sections. In free-floating IC cell cultures, neurospheres formed from animals from early postnatal to adulthood. The amount of generated neurospheres decreased in older ages and increased with the number of cell line passages. Cells in the neurospheres and the histological sections stained positively with NSC markers (Doublecortin, Sox-2, Musashi-1, Nestin, and Atoh1). Dissociated single cells from the neurospheres differentiated and were stained positively for the neural lineage markers β-III-tubulin, glial fibrillary acidic protein, and myelin basic protein. In addition, NSC markers (Doublecortin, Sox-2, CDK5R1, and Ascl-1) were investigated by qRT-PCR. In conclusion, a neurogenic potential in the rat IC was detected and evaluated from early postnatal days until adulthood. The identification of NSCs in the rat IC and their age-specific characteristics contribute to a better understanding of the development and the plasticity of the auditory pathway and might be activated for therapeutic use.
Social Networks and Workers’ Earnings in Contemporary China
Authors: Wu Qiong , Wallace Michael 
Published: October 2020

AbstractGuanxi is the central form of social capital in Chinese society that provides access to resources, assets, and benefits that facilitate social status and social mobility. Substantial empirical research has documented the importance of guanxi networks in accessing resources for getting good jobs, moving up to better jobs, and achieving higher wages. Chinese Lunar New Year is a special occasion of cultural and social significance to cultivate and maintain guanxi networks. We thus conceptualize guanxi networks as the visiting networks during the Chinese New Year celebration. Using the 2008 Chinese General Social Survey, we construct five measures of the Chinese New Year greeting networks and assess their impact on workers’ earnings as well as gender differences in their effects on earnings. We also consider two major structural constraints—the hukou and social class—that affect the extent of one’s social networks and earnings. Our findings not only confirm the overall positive effects of the Chinese New Year greeting networks on earnings but also offer nuances that enhance the understanding of how guanxi networks as a manifestation of social capital embedded in Chinese traditional culture work in the contemporary era and intensify gender gaps.
Integrated optimisation for production capacity, raw material ordering and production planning under time and quantity uncertainties based on two case studies
Authors: Xu Wei , Song Dong-Ping 
Published: October 2020

AbstractThis paper develops a supply chain (SC) model by integrating raw material ordering and production planning, and production capacity decisions based upon two case studies in manufacturing firms. Multiple types of uncertainties are considered; including: time-related uncertainty (that exists in lead-time and delay) and quantity-related uncertainty (that exists in information and material flows). The SC model consists of several sub-models, which are first formulated mathematically. Simulation (simulation-based stochastic approximation) and genetic algorithm tools are then developed to evaluate several non-parameterised strategies and optimise two parameterised strategies. Experiments are conducted to contrast these strategies, quantify their relative performance, and illustrate the value of information and the impact of uncertainties. These case studies provide useful insights into understanding to what degree the integrated planning model including production capacity decisions could benefit economically in different scenarios, which types of data should be shared, and how these data could be utilised to achieve a better SC system. This study provides insights for small and middle-sized firm management to make better decisions regarding production capacity issues with respect to external uncertainty and/or disruptions; e.g. trade wars and pandemics.
Influence of the Addition of Spruce Fibers to Industrial-Type High-Density Fiberboards Produced with Recycled Fibers
Authors: Sala Conrad M. , Robles Eduardo , Kowaluk Grzegorz 
Published: October 2020

Abstract
The growing production of wood-based panels and the linked consumption result in a need for substituting standard wooden raw materials. The shortage of wood availability, as well as the increasing prices and a trend towards more environmentally friendly materials and processes, have encouraged the producers of wood-based products to consider extending the life cycle of wood composites. In the present work, the influence of substituting pine with spruce for industrial high-density fiberboards with 5% of recovered fibers was studied. Samples containing 0%, 25%, 50%, and 100% spruce fibers were tested in their mechanical resistance and their interaction with water. Boards from all samples met relevant standard requirements; however, the addition of spruce caused a decrease in mechanical properties, with homogeneity having the most significant influence. The modulus of rupture dropped up to 6% and the internal bond for 47% for samples having 50% of spruce. The most significant drop (50%) was observed for surface soundness for samples made with 100% spruce. Regarding physical properties, swelling increased up to 19% with 50% spruce; on the other hand, its water absorption decreased for up to 12%. The addition of spruce to industrial high-density fiberboards also influenced the formaldehyde content negatively, with an increase of up to 21% with 50% spruce.

A fully coupled thermo-mechanical numerical modelling of the refill friction stir spot welding process in Alclad 7075-T6 aluminium alloy sheets
Authors: Kubit Andrzej , Trzepiecinski Tomasz 
Published: October 2020

AbstractRefill friction stir spot welding (RFSSW) is a solid state joining technology that has the potential to replace processes such as the open-air fusion bonding technique and rivet technology in aerospace applications. Selection of proper RFSSW parameters is a crucial task which is important to ensure the mechanical strength of the joint. The aim of this paper is to undertake numerical modelling of the RFSSW process to understand the physics of the welding process, which involves large deformations, complex contact conditions and steep temperature gradients. Three-dimensional fully coupled thermo-mechanical models of RFSSW joints between Alclad 7075-T6 aluminium alloy sheets have been built in the finite-element-based program Simufact Forming. The simulation results included the temperature distribution and the stress and strain distributions in the overlap joint. The results of numerical computations have been compared with experimental ones. The numerical model was able to predict the mechanics of material flow during the joining of sheets of Alclad aluminium alloys using RFSSW. The predictions of the temperature gradient in the weld zone were in good agreement with the temperature measured experimentally. The numerical models that have been built are capable of simulating RFSSW to reduce the number of experiments required to set optimal welding parameters.
The effect of social feedback from peers on adolescent cognitive control
Authors: Hollarek Miriam , Lee Nikki C. , Krabbendam Lydia 
Published: October 2020

ABSTRACTIntroductionSocial feedback can influence cognitive control during adolescence, particularly if provided by peers. The main aim of this study was to investigate if feedback given by liked or disliked peers differentially influenced adolescents' cognitive control. The second aim was to investigate if these effects could be linked to the participants’ social embeddedness in their classroom.MethodsA personalized incentive go/no‐go task was administered to 45 early adolescents (M = 11.6 years, 25 male) and 68 late adolescents (M = 16.7, 38 male) in the Netherlands. Feedback was given after no‐go trials in two social feedback conditions (displaying a picture of a real liked or disliked classmate) and in a non‐social control condition.ResultsPerformance on the task significantly improved with age. We found no differences between conditions in cognitive control, as measured by d‐prime. However, analysis of task speed revealed slower reaction times during the liked peer condition as compared to the disliked peer and the control condition, potentially suggesting that participants responded more cautiously, or alternatively that participants were more distracted. These effects did not differ between age groups. Participants’ differences in task performance were not reflected in their social embeddedness in the classroom.ConclusionsThis study shows that the same kind of social feedback can have different effects on adolescent behaviour depending on the peer delivering the feedback. It demonstrates the importance of studying the effects of real life social environments to better understand and utilize their impact on adolescent development.
