AbstractTwo systems of additive equations were developed to predict aboveground stand level biomass in log products and harvest residue from routinely measured or predicted stand variables forPinus radiataplantations in New South Wales, Australia. These plantations were managed under three thinning regimes or stand types before clear-felling at rotation age by cut-to-length harvesters to produce sawlogs and pulpwood. The residue material following a clear-fell operation mainly consisted of stumps, branches and treetops, short off-cut and waste sections due to stem deformity, defects, damage and breakage. One system of equations did not include dummy variables for stand types in the model specification and was intended for more general use in plantations where stand density management regimes were not the same as the stand types in our study. The other system that incorporated dummy variables was for stand type-specific applications. Both systems of equations were estimated using 61 plot-based estimates of biomass in commercial logs and residue components that were derived from systems of equations developed in situ for predicting the product and residue biomass of individual trees. To cater for all practical applications, two sets of parameters were estimated for each system of equations for predicting component and total aboveground stand biomass in fresh and dry weight respectively. The two sets of parameters for the system of equations without dummy variables were jointly estimated to improve statistical efficiency in parameter estimation. The predictive performances of the two systems of equations were benchmarked through a leave-one-plot-out cross validation procedure. They were generally superior to the performance of an alternative two-stage approach that combined an additive system for major components with an allocative system for sub-components. As using forest harvest residue biomass for bioenergy has increasingly become an integrated part of forestry, reliable estimates of product and residue biomass will assist harvest and management planning for clear-fell operations that integrate cut-to-length log production with residue harvesting.

Published: April 2021

AbstractPurpose of ReviewWe summarized peer-reviewed literature on aggressive episodes perpetrated by adult patients admitted to general hospital units, especially psychiatry or emergency services. We examined the main factors associated with aggressive behaviors in the hospital setting, with a special focus on the European experience.Recent FindingsA number of variables, including individual, historical, and contextual variables, are significant risk factors for aggression among hospitalized people. Drug abuse can be considered a trans-dimensional variable which deserves particular attention.SummaryAlthough mental health disorders represent a significant component in the risk of aggression, there are many factors including drug abuse, past history of physically aggressive behavior, childhood abuse, social and cultural patterns, relational factors, and contextual variables that can increase the risk of overt aggressive behavior in the general hospital. This review highlights the need to undertake initiatives aimed to enhance understanding, prevention, and management of violence in general hospital settings across Europe.
Contract killings: a crime script analysis
Authors: de Korte Laura R. , Kleemans Edward R. 
Published: April 2021

AbstractThis article contributes to our existing knowledge through a crime script analysis of contract killings, based on six extensively analyzed police investigations in the Netherlands. Starting from a universal crime script, a more specific crime script for contract killings is elaborated. To provide a clear picture of the whole process, the description of the scenes focuses on requirements, facilitators, modi operandi, and preparatory actions. A comparison of liquidation investigations is made through a crime script analysis, which results in three types of requirements: vehicles, automatic weapons, and technical equipment, including PGP-telephones and beacons. In addition, spy shops turn out to play a major role in liquidations as facilitators. Due to a lack of licensing and regulations, the owners of spy shops can decide to a large extent on their own procedures. This leads to the possibility of buying and selling equipment anonymously and with large amounts of cash, which facilitates the preparation of liquidations and crime in general. Hitmen are the second type of important facilitators. The analysis reveals that all liquidation investigations contain indications of a principal to whom account has to be held. Two investigations clearly demonstrate financial rewards for contract killings.
Shaping space. A conceptual framework on the connections between organised crime groups and territories
Authors: Sergi Anna , Storti Luca 
Published: April 2021

AbstractThis paper, which is the introduction to this special issue on ‘Spaces of Organised Crime’, aims to analyse the nexus between organised crime groups and territories. Such groups are able to exploit resources that circulate within territorial contexts in which they are embedded. They also operate concretely as entities that can take part to the transformation ofspacesintoplaces. Accordingly, we will lay out an analytical model about the processes through which organised crime groups contribute to create and shapeterritories. We show how these processes link with the main types of organised crime groups on a differentiated basis. In the last section of this introduction, we present the papers included in the special issue and the logic connecting them to one another.
Infidelity in Relation to Sex and Gender: The Perspective of Sociobiology Versus the Perspective of Sociology of Emotions
Authors: Wróblewska-Skrzek Joanna 
Published: April 2021

AbstractIt is not the main intention of this paper to prove that people are unfaithful, neither does it present the scale of the phenomenon, as it is hard, for objective reasons, to obtain reliable data on the subject. The text analyses the motives for, and consequences of infidelity from two different perspectives: sociobiology and the sociology of emotions, while gender constitutes the axis of analysis. Regardless of whether we will explain infidelity as motivated by human nature, drives, desires and genes, or treat it as a social construct, the argumentation for infidelity remains different for men and for women. What is more, both subdisciplines bring into light different consequences of infidelity for representatives of either sex.
Why is LCIS Important—Pathological Review
Authors: Shaaban Abeer M. 
Published: April 2021

Abstract
Purpose of Review
Lobular carcinoma in situ (LCIS) encompasses classical LCIS and other rarer and more recently recognised variants, namely pleomorphic LCIS (PLCIS) and florid LCIS. Each of those entities has characteristic histological diagnostic criteria, different rates of underestimation of malignancy and recommended management. In addition, those lesions can mimic a number of benign and malignant breast lesions and can particularly be mistaken for ductal carcinoma in situ (DCIS). Accurate diagnosis of those lesions is critical to ensuring the appropriate patient management.

Recent Findings
Several international guidelines refining the pathological classification, staging and management of those lesions have recently been updated. This review will provide an up-to-date pathological overview of the current knowledge of LCIS with emphasis on the multidisciplinary management implications.

Summary
Close correlation between imaging and pathology in a multidisciplinary pathway is essential in LCIS management. Classical LCIS on core biopsy/vacuum-assisted biopsy (VAB) is coded as B3 and, if without discordant imaging, should further be sampled by vacuum-assisted excision (VAE). PLCIS should be coded and managed as per high-grade DCIS. Florid LCIS is a rare entity that is thought to be more aggressive than classical LCIS. Excision with clear margin is advised.

Published: April 2021

AbstractThe canteen and laboratory of every academic organization need a lot of clean water, and it generates equivalent amount of wastewater every hour which is neither purified nor reused. Due to water scarcity, the recycling and reusing of wastewater become very essential. The present study describes the simple and cost-effective method for the design of a small-scale wastewater treatment plant for the purification of wastewater generated by household, canteen and laboratory of an academic institute. The current study explored the process of phytoremediation by Typha latifolia L. and Canna indica L. for removal of metal ions and phosphate ions from the wastewater. The partially treated water after phytoremediation was further purified by sand filtration. The various water quality parameters (pH, hardness, dissolved oxygen, chemical oxygen demand, turbidity, total dissolved solids and metal ions) of the treated and untreated water were analyzed. It was observed that there are significant reduction in hardness, turbidity and chemical oxygen demand and increase in dissolved oxygen value. The treated water can be reused for various household works and agriculture.

Published: April 2021

AbstractIn the present study, the arsenic bioremediation ability of Bacillus licheniformis (dubbed as A6) was determined. The strain was isolated from metal polluted wastewater and was identified on the basis of 16S rRNA sequence homology with accession number of KX 785,171. The bacterium showed resistance against multiple toxic heavy metals, and MIC against arsenic was 3000 µg/ml. Resistance of the bacterium against other toxic metal ions was 3000 µg/ml (Cr), 50 µg/ml (Hg), 1000 µg/ml (Mn), 4000 µg/ml (Se), 500 µg/ml (Pb), 100 µg/ml (Co), 70 µg/ml (Cd) and 100 µg/ml (Zn). The optimum growth temperature was 37 °C while pH was 7. The strain also showed resistance against commonly used antibiotics except ceftriaxone 30 µg and amoxicillin with clavulanic acid (2:1) 3 µg. B. licheniformis could oxidize arsenite into arsenate 86 and 98% after 48 and 96 h from the medium at optimum growth conditions. Due to its high oxidation potential, B. licheniformis can be used in the biological treatment of wastewater containing arsenic.

Published: April 2021

Abstract
Blood flow in the aorta is often assumed laminar, however aortic valve pathologies may induce transition to turbulence and our understanding of turbulence effects is incomplete. The aim of the study was to provide a detailed analysis of turbulence effects in aortic valve stenosis (AVS).

Methods
Large-eddy simulation (LES) of flow through a patient-specific aorta with AVS was conducted. Magnetic resonance imaging (MRI) was performed and used for geometric reconstruction and patient-specific boundary conditions. Computed velocity field was compared with 4D flow MRI to check qualitative and quantitative consistency. The effect of turbulence was evaluated in terms of fluctuating kinetic energy, turbulence-related wall shear stress (WSS) and energy loss.

Results
Our analysis suggested that turbulence was induced by a combination of a high velocity jet impinging on the arterial wall and a dilated ascending aorta which provided sufficient space for turbulence to develop. Turbulent WSS contributed to 40% of the total WSS in the ascending aorta and 38% in the entire aorta. Viscous and turbulent irreversible energy losses accounted for 3.9 and 2.7% of the total stroke work, respectively.

Conclusions
This study demonstrates the importance of turbulence in assessing aortic haemodynamics in a patient with AVS. Neglecting the turbulent contribution to WSS could potentially result in a significant underestimation of the total WSS. Further work is warranted to extend the analysis to more AVS cases and patients with other aortic valve diseases.

Published: April 2021

AbstractA flow reactor for the complex reaction network of the free radical solution polymerization of n-butyl acrylate was optimized by a combination of kinetic modeling, computational fluid dynamics (CFD) and additive manufacturing. CFD was used to model a flow reactor with SMX mixing elements. An optimized geometry was 3D-printed from polypropylene. The modeled residence time behavior was compared to relevant experiments, giving a validation for the flow behavior of the reactor. A kinetic model for the free radical solution polymerization of n-butyl acrylate (BA) was in addition implemented into the CFD model. It was used to predict the polymerization behavior in the flow reactor and the resulting product properties. The experimental and computational results were in acceptable agreement.

Bioengineering of the Uterus
Authors: Yoshimasa Yushi , Maruyama Tetsuo 
Published: April 2021

AbstractImpairment of uterine structure and function causes infertility, pregnancy loss, and perinatal complications in humans. Some types of uterine impairments such as Asherman’s syndrome, also known as uterine synechiae, can be treated medically and surgically in a standard clinical setting, but absolute defects of uterine function or structure cannot be cured by conventional approaches. To overcome such hurdles, partial or whole regeneration and reconstruction of the uterus have recently emerged as new therapeutic strategies. Transplantation of the whole uterus into patients with uterine agenesis results in the successful birth of children. However, it remains an experimental treatment with numerous difficulties such as the need for continuous and long-term use of immunosuppressive drugs until a live birth is achieved. Thus, the generation of the uterus by tissue engineering technologies has become an alternative but indispensable therapeutic strategy to treat patients without a functional or well-structured uterus. For the past 20 years, the bioengineering of the uterus has been studied intensively in animal models, providing the basis for clinical applications. A variety of templates and scaffolds made from natural biomaterials, synthetic materials, or decellularized matrices have been characterized to efficiently generate the uterus in a manner similar to the bioengineering of other organs and tissues. The goal of this review is to provide a comprehensive overview and perspectives of uterine bioengineering focusing on the type, preparation, and characteristics of the currently available scaffolds.
Local content implementation and development in Ghana’s upstream oil and gas sector for sustainable development: contemporary issues on policy management
Authors: Suleman Shafic , Zaato Joshua Jebuntie 
Published: April 2021

AbstractThe need to develop and boost the potentials of Ghana’s upstream oil and gas activities has been advocated by policymakers, academics, and financial institutions since the discovery of oil and gas in commercial quantities. It has been argued that if well implemented, upstream activities have a trickledown effect on the local content policy linkages that apart from taxes, can lead to improved financial and social benefits. In this study, how Ghana can use local content policy in upstream oil and gas operations to maximum economic and social benefits for the good of the Ghana government, citizens, and the Multinational Oil Companies, is the main question to be answered? To address this question, comprehensive analysis of local content laws and policies and stakeholder consultations are conducted. The paper argues that an effective local content policy towards achieving sustainability in the upstream oil and gas industry demands balancing the needs of policymakers, local communities, Multinational Oil Companies, and regulators to succeed. The study recommends a local content implementation master plan; active participation of key stakeholders (government, citizens and Multinational Oil Companies); and integration of forward and backward linkages in the implementation of Ghana’s upstream local content laws and policies.
Bidding behavior in auctions versus posted prices: comparisons of mean and marginal effects
Authors: Wu Shang , Fooks Jacob R. , Li Tongzhe , Messer Kent D. , Delaney Deborah A. 
Published: April 2021

Abstract
Economic experiments have been widely used to elicit individuals' evaluation for various commodities. Common elicitation methods include auction and posted price mechanisms. A field experiment is designed to compare willingness-to-pay (WTP) estimates between these two mechanisms. Despite both of these formats being theoretically incentive compatible and demand revealing, results from 115 adult consumers indicate that WTP estimates obtained from an auction are 32–39 percent smaller than those from a posted price mechanism. A comparison in statistical significance shows that auctions require a smaller sample size than posted price mechanisms in order to detect the same preference change. Nevertheless, the signs of marginal effects for different product characteristics are consistent in both mechanisms.

AbstractBackground:Physical distancing among healthcare workers (HCWs) is an essential strategy in preventing HCW-to-HCWs transmission of severe acute respiratory coronavirus virus 2 (SARS-CoV-2).Objective:To understand barriers to physical distancing among HCWs on an inpatient unit and identify strategies for improvement.Design:Qualitative study including observations and semistructured interviews conducted over 3 months.Setting:A non–COVID-19 adult general medical unit in an academic tertiary-care hospital.Participants:HCWs based on the unit.Methods:We performed a qualitative study in which we (1) observed HCW activities and proximity to each other on the unit during weekday shifts July–October 2020 and (2) conducted semi-structured interviews of HCWs to understand their experiences with and perspectives of physical distancing in the hospital. Qualitative data were coded based on a human-factors engineering model.Results:We completed 25 hours of observations and 20 HCW interviews. High-risk interactions often occurred during handoffs of care at shift changes and patient rounds, when HCWs gathered regularly in close proximity for at least 15 minutes. Identified barriers included spacing and availability of computers, the need to communicate confidential patient information, and the desire to maintain relationships at work.Conclusions:Physical distancing can be improved in hospitals by restructuring computer workstations, work rooms, and break rooms; applying visible cognitive aids; adapting shift times; and supporting rounds and meetings with virtual conferencing. Additional strategies to promote staff adherence to physical distancing include rewarding positive behaviors, having peer leaders model physical distancing, and encouraging additional safe avenues for social connection at a safe distance.
The Two Faces of the Hungarian Empire
Authors: Varga Bálint 
Published: April 2021

AbstractThis article investigates the uses of the term “Hungarian Empire” during the long nineteenth century. It argues that the term “empire” emerged in the Hungarian political discourse in the Vormärz era and it was used to denote the imagined integrity of Hungary proper, Transylvania, Croatia, Slavonia, and eventually Dalmatia on the grounds of the historic rights of the Holy Crown of Hungary in the form of a composite nation-state. This usage of the term became ubiquitous after the Austro-Hungarian Compromise. A second meaning pertaining to imperialist foreign policy entered the dictionary of Hungarian political discourse in the late nineteenth century. Fed by the recently created memory of the medieval Hungarian great power, several pressure groups in fin-de-siècle Hungary lobbied for a Hungarian (informal) empire in Southeastern Europe and beyond. While several lobby groups were firmly embedded in the framework of the Austro-Hungarian monarchy, some of these visionaries imagined a Hungarian empire independent from the Habsburg structures. A short comparison with the Croatian and Czech political discourses illuminates that the first meaning of empire (composite nation-state) did not differ in substance from contemporary terminology in other Habsburg lands but the second meaning (imperialism) was indeed a unique phenomenon in the Habsburg monarchy.
Ester, a Missing Clasp, and Jewish Pawnbroking Networks in Renaissance Prague
Authors: Parker Anna 
Published: April 2021

AbstractIn 1577, a petty pawnbroker named Ester lost a clasp belonging to a Prague noblewoman, Lady Juliana the Fifth. Having been traded repeatedly between anonymous pawnbrokers, the clasp was eventually tracked down in the Polish city of Poznań, by which time Ester had already fled Prague and taken refuge in Cracow. In this essay, I use the subsequent criminal court case to explore this illuminating episode in the history of the city's Jewish Quarter. Taking place in the late Renaissance, during what has often been referred to as the Jewish “Golden Age,” I argue that this dramatic event provides access to the realities of an era often characterized as harmonious. I position pawnbroking as an industry that invited intimate and regular cross-confessional contact, and one that therefore offers up new opportunities to consider the nature of coexistence. By following the movement of both Ester and the pawned clasp from Prague to Poland, I also show how attention to pawnbroking can illuminate a constellation of transregional connections that stretched from Bohemia to the Polish-Lithuanian Commonwealth to its east, revealing the otherwise unrecorded ways in which Prague's Jews were connected to the Ashkenazi diaspora.
