(Sea)ways of Perception: an Integrated Maritime-Terrestrial Approach to Modelling Prehistoric Seafaring
Authors: Blankshein Stephanie L. 
Published: September 2021

AbstractThe seaways have played a significant role in the movement of people, goods and ideologies since prehistory; yet, the ephemerality of movement combined with the paucity of direct evidence for prehistoric seafaring has challenged more refined understandings of the role of early seafaring in anthropogeny. Advances in digital methodologies within archaeology, such as least-cost approaches, allow more nuanced models of movement to be generated but suffer from dichotomous approaches to land and sea. These disentangled land-sea perspectives have long been criticised as ineffectual for understanding past maritime cultures, and previous discussions of prehistoric seafaring more specifically have advocated the consideration of the unique character of maritime space in order to more closely actuate a seafarer’s perspective. Drawing on these ideas, this paper argues that more nuanced approaches to past seafaring are not only necessary but also achievable through holistic perspectives, heuristic methods and scaled-down resolutions, which allow for a more contextualised understanding of the spatiality and temporality—i.e. the human-scale—of maritime movement. This will be demonstrated through an integrated land-sea least-cost method to model Neolithic seafaring around the Outer Hebrides of Scotland. It is not the intention of this paper to advocate solely for the methodology outlined here but rather to demonstrate the need to consider and understand the unique character of maritime space and its many influences on the practices being studied. Only through such contextualised cognition can the perspectives and ideologies of past seafarers and the role of seafaring in anthropogeny truly be understood.

AbstractFew studies have evaluated the short-term association between hospital admissions and individual exposure to ambient particulate matter (PM2.5). Particularly, no studies focused on hospital admissions for chronic obstructive pulmonary disease (COPD) at the individual level. We assessed the short-term effects of PM2.5 on hospitalization admissions for COPD in Guangzhou, China, during 2014–2015, based on satellite-derived estimates of ambient PM2.5 concentrations at a 1-km resolution near the residential address as individual-level exposure for each patient. Around 40,002 patients with COPD admitted to 110 hospitals were included in this study. A time-stratified case-crossover design with conditional logistic regression models was applied to assess the effects of PM2.5 based on a 1-km grid data of aerosol optical depth provided by the National Aeronautics and Space Administration on hospital admissions for COPD. Further, we performed stratified analyses by individual demographic characteristics and season of hospital admission. Around 10 μg/m3 increase in individual-level PM2.5 was associated with an increase of 1.6% (95% confidence interval [CI]: 0.6%, 2.7%) in hospitalization for COPD at a lag of 0–5 days. The impact of PM2.5 on hospitalization for COPD was greater significantly in males and patients admitted in summer. Our study strengthened the evidence for the adverse effect of PM2.5 based on satellite-based individual-level exposure data.
Housing Conditions and Adolescents’ Socioemotional Well-being: An Empirical Examination from China

Published: September 2021

AbstractThis paper examines the association between housing and adolescents’ socioemotional well-being in China using a large nationally representative dataset from the 2016 China Family Panel Studies (CFPS). The results showed that housing conditions were negatively correlated with adolescents’ depression and positively correlated with subjective well-being when family income was controlled. However, homeownership did not predict adolescent’s subjective well-being and depression. Adolescents living in urban areas have better socioemotional well-being than adolescents living in rural areas, as demonstrated by their higher subjective well-being, lower depression, and higher self-esteem. Both urban and rural adolescents were influenced by housing conditions in a similar pattern. In addition, self-esteem mediated the relationship between housing conditions and adolescents’ socioemotional well-being. The results indicate that housing conditions are an important factor for policymakers to consider when promoting children’s well-being in China.
How valuation approach choice affects financial analysts’ target price accuracy
Authors: Erkilet Gülcan , Janke Gerrit , Kasperzak Rainer 
Published: September 2021

AbstractThis paper examines which valuation approaches financial analysts use to value a company and whether the chosen valuation approach affects the target price accuracy. To address these questions, we conduct content analyses of 867 hand-collected analyst reports on German publicly listed companies published between January 2014 and June 2017. We find that sell-side analysts more frequently use the single-period market approach when formulating target prices, followed by the multi-period income approach, and a mixture of both by combining the results, the so-called hybrid valuation approach. Additionally, we show that 612 of the analyzed analyst reports are based on a holistic valuation methodology instead of a sum of the parts valuation technique. Both univariate and multivariate analyses emphasize that the choice of valuation approach is significantly associated with the accuracy of price targets. Specifically, the income and market approach lead to significantly more accurate target prices compared to the hybrid approach. We also find that the target price accuracy is higher when analysts apply the holistic rather than the sum of the parts valuation approach to determine the fundamental value of the company. Additional results emphasize that target price accuracy improves when analysts use the sum of the parts valuation that bases solely on market or income approaches rather than hybrid approaches. Hence, we contribute to theory and practice by providing evidence on the link between the choice of valuation approach and the analysts’ target price accuracy as well as on the performance of certain valuation techniques.

Abstract
The addition of grain refiner particles in the aluminum melt is known to reduce the filtration efficiency of ceramic foam filter (CFF). In the present work, a systematic study on the influence of the addition level of Al-Ti-B master alloys and the inclusion level on the filtration performance of aluminum melt has been investigated by pilot-scale filtration tests using 50 PPi and 80 PPi filters. The inclusion level of the melt has been measured using both LiMCA and PoDFA. For 80 PPi CFF, the N20 inclusion (diameter larger than 20 μm) value in the post-filtrated melt does not increase when an ultra-high level of inclusions is introduced in the form of chips. For the melts with a low level of grain refiners (~ 0.5 kg/ton), the filtration performance of CFF is not affected by grain refiners, regardless of inclusion load. An addition of 2.0 kg/ton grain refiners reduces the filtration performance for melts with a high inclusion level, where post-filtration inclusions with the size of 15-20 µm were significantly increased. It is found, however, for the melts with an ultra-high inclusion load, the filtration performance of 80 PPi CFF is not affected by the grain refiner addition up to 2.0 kg/ton. The interactions between inclusions and grain refiner particles and the filtration mechanism have been studied by characterizing the spent filter and measuring the pressure drop during the filtration process. It is revealed that the strong adherence between oxide film with grain refiner particles dominates the grain refiner influence on the filtration performance of CFF. During the filtration process, oxide films have strong influences on the capturing of other inclusions such as oxide particles and TiB2 particles by the filter. A mechanism based on the interactions between oxide films and grain refiner particles is proposed to explain the CFF performance under the influence of grain refiner.

AbstractWidespread regional gray matter volume (GMV) alterations have been reported in bipolar disorder (BD). Structural networks, which are thought to better reflect the complex multivariate organization of the brain, and their clinical and psychological function have not been investigated yet in BD. 24 patients with BD type-I (BD-I), and 30 with BD type-II (BD-II), and 45 controls underwent MRI scan. Voxel-based morphometry and source-based morphometry (SBM) were performed to extract structural covariation patterns of GMV. SBM components associated with morphometric differences were compared among diagnoses. Executive function and emotional processing correlated with morphometric characteristics. Compared to controls, BD-I showed reduced GMV in the temporo-insular-parieto-occipital cortex and in the culmen. An SBM component spanning the prefrontal-temporal-occipital network exhibited significantly lower GMV in BD-I compared to controls, but not between the other groups. The structural network covariance in BD-I was associated with the number of previous manic episodes and with worse executive performance. Compared to BD-II, BD-I showed a loss of GMV in the temporal-occipital regions, and this was correlated with impaired emotional processing. Altered prefrontal-temporal-occipital network structure could reflect a neural signature associated with visuospatial processing and problem-solving impairments as well as emotional processing and illness severity in BD-I.
Transfer of Self-Leadership Skills Within the Dutch Police: a Three-Wave Study

Published: September 2021

AbstractThis three-wave study examined the training-to-work transfer process of a self-leadership skills training programme for crime scene investigators working for the Dutch police force. The transfer process is complex and depends on numerous factors. Two important steps forward are taken in the present study. First, we take into account all transfer steps in one study to gain insights into the transfer process, and second, by being specific about the work situation in which transfer outcomes should occur, we address the “criterion problem” that is often mentioned in transfer research. Based on the Ability Motivation Opportunity model, we hypothesised that the posttraining transfer process starts with being motivated to transfer and that this motivation increases the use of self-leadership during work. Another aspect that may facilitate the use of trained skills is supervisor support, as it offers opportunities to use self-leadership skills during work. In turn, self-leadership skills at work were hypothesised to lead to increased work performance. We tested our transfer model in two different work situations experienced by crime fighters. Our findings show that the use of self-leadership skills is positively related to the detached concern of crime fighters in specific situations. Additionally, our findings show that the use of self-leadership skills mediates the relation between the motivation to transfer and work performance in specific situations. Finally, our findings show that including different transfer steps (i.e. the motivation to transfer, use of skills, and performance), different performance measures, and different work situations in the transfer process provides more insight into when and how transfer-to-work after training occurs. These findings suggest that if organisations aspire to improve such transfer, then they should be specific about the intended posttraining behaviours and performance and the situations in which these outcomes should emerge.

Published: September 2021

AbstractThe field of digital forensics has grown exponentially to include a variety of digital devices on which digitally stored information can be processed and used for different types of crimes. As a result, as this growth continues, new challenges for those conducting digital forensic examinations emerge. Digital forensics has become mainstream and grown in importance in situations where digital devices used in the commission of a crime need examining. This article reviews existing literature and highlights the challenges while exploring the lifecycle of a mobile phone examination and how the disclosure and admissibility of digital evidence develops.

AbstractThree new reference materials: MODAS-3 Herring Tissue (M-3 HerTis), MODAS-4 Cormorant Tissue (M-4 CormTis), and MODAS-5 Cod Tissue (M-5 CodTis) were prepared and certified on the basis of results of a worldwide intercomparison exercise. Independently of our proven method of establishing the certified and information values, the content of several essential and toxic elements was additionally determined by the use of ratio primary reference measurement procedures (definitive methods) based on radiochemical neutron activation analysis (RNAA) in the case of As, Cd, Co, Cr, Fe, Mo, Se, and U and isotope dilution mass spectrometry (IDMS) in the case of Hg, respectively. Good agreement of the established certified values and the results obtained by ratio primary reference measurement procedures confirmed the validity of the certification procedure. The total number of elements which could be certified amounted to 30, 21, 18 in M-3 HerTis, M-4 CormTis, and M-5 CodTis, respectively. The relative frequency of use of individual analytical techniques in this intercomparison campaign was calculated and discussed. Inductively coupled plasma mass spectrometry (ICP-MS) is now a dominant technique, followed by atomic absorption spectroscopy (AAS), NAA, and emission spectroscopy (ES). The decreasing share of NAA as compared to several earlier intercomparison exercises should be noticed. NAA is the only method in the array of highly sensitive methods of inorganic trace analysis, which is essentially free from blank. The lack of this method in the foreseeable future may be an obstacle in the prospective certification campaigns and may endanger the implementation of quality assurance in trace analysis.
Gonfienti (Prato, Tuscany, Central Italy), a zooarchaeological snapshot on daily sixth-century Etruscan household life

Published: September 2021

Abstract

While Etruscan sites have received considerable attention over the years, scholarly focus has rarely been directed on the faunal remains from the various celebrated archaeological localities. The present is a zooarchaeological analysis of archaeofaunal material from Gonfienti, a renowned Etruscan locality near Prato, in north-central Tuscany. The vast, complex archaeological site includes a large building, called Edifice 1, that was constructed starting from the sixth century BC. Predominant taphonomic signatures, human-induced damage, archaeobiological evidence and mortality patterns obtained from the study of the faunal remains from the building’s main phase of occupation revealed that the householders depended principally on cattle and subordinately on domestic suids for much of their subsistence, although game also formed part of the diet. The zooarchaeological interpretations match up very well with the interpretations of the excavators and archaeologists concerning the function of Edifice 1 and the use of some of its rooms. In addition, the low incidence of in situ weathering, extensive corrosion of cortical bone surfaces possibly by exposure to alkaline solutions and the relatively high frequency of waterfowls in the studied samples suggest that the area hosting Edifice 1 experienced very humid conditions and was surrounded by large wetland expanses at the time of its main Etruscan occupation.
Effect of density dependence on coinfection dynamics

Published: September 2021

AbstractIn this paper we develop a compartmental model of SIR type (the abbreviation refers to the number of Susceptible, Infected and Recovered people) that models the population dynamics of two diseases that can coinfect. We discuss how the underlying dynamics depends on the carrying capacity K: from a simple dynamics to a more complex. This can also help in understanding the appearance of more complicated dynamics, for example, chaos and periodic oscillations, for large values of K. It is also presented that pathogens can invade in population and their invasion depends on the carrying capacity K which shows that the progression of disease in population depends on carrying capacity. More specifically, we establish all possible scenarios (the so-called transition diagrams) describing an evolution of an (always unique) locally stable equilibrium state (with only non-negative compartments) for fixed fundamental parameters (density independent transmission and vital rates) as a function of the carrying capacity K. An important implication of our results is the following important observation. Note that one can regard the value of K as the natural ‘size’ (the capacity) of a habitat. From this point of view, an isolation of individuals (the strategy which showed its efficiency for COVID-19 in various countries) into smaller resp. larger groups can be modelled by smaller resp. bigger values of K. Then we conclude that the infection dynamics becomes more complex for larger groups, as it fairly maybe expected for values of the reproduction number $$R_0\approx 1$$

R

. We show even more, that for the values $$R_0>1$$

there are several (in fact four different) distinguished scenarios where the infection complexity (the number of nonzero infected classes) arises with growing K. Our approach is based on a bifurcation analysis which allows to generalize considerably the previous Lotka-Volterra model considered previously in Ghersheen et al. (Math Meth Appl Sci 42(8), 2019).
Different response of perennial ryegrass—Epichloë endophyte symbiota to the elevated concentration of heavy metals in soil
Authors: Żurek Grzegorz , Wiewióra Barbara , Rybka Krystyna , Prokopiuk Kamil 
Published: September 2021

AbstractThe phenomenon of plant mutualistic symbiosis with microbes may have a positive effect on the improvement of plant tolerance to environmental stresses as well as on the ability of plants to accumulate heavy metal (HM) ions from soil. The influence ofEpichloëfungal endophyte (Ascomycota,Clavicipitaceae) on perennial ryegrass (Lolium perenneL.) plants grown in the presence of elevated concentrations of HM ions (Cd2+, Pb2+, and Cu2+) in soil was studied. The presence ofEpichloëin the host grass tissues resulted in different accumulation of HM ions in the aboveground parts of the plants. In some cases, endophyte infection positively affected ryegrass ability to accumulate HM ions from soil. In plants with (E +) and without (E −) endophytes, the hormesis effect was induced by the elevated concentration of Cu2+ions, resulting in better growth and photosynthesis, as examined by measurements of Chlafluorescence. The obtained results indicate that based on the laboratory evaluation of the efficiency of HM accumulation, we were able to choose the best associations of perennial ryegrass with endophytes for HM phytoremediation.

Published: September 2021

SamenvattingHet doel van deze studie was de oncologische en functionele uitkomsten van salvage cryochirurgie (sCC) te beoordelen bij lokaal recidief prostaatcarcinoom na radiotherapie (rrPCA). De studie werd uitgevoerd bij 169 patiënten. Er vond retrospectieve analyse plaats van recidiefvrije overleving (BRFS), algehele overleving, metastasevrije overleving, androgeendeprivatietherapie (ADT)-vrije overleving, functionele uitkomsten en complicaties. De mediane follow-up was 36 maanden (IQR = 18–66). BRFS na vijf en acht jaar was 52% (95%-BI = 43–62) en 45% (95%-BI = 35–57), respectievelijk. PSA bij initiële diagnose, de initiële behandeling, het interval tussen de primaire behandeling en SCS, leeftijd bij SCS en post-SCS PSA-nadir waren significante voorspellers van BRFS. De vijf-jaars ADT-vrije overleving was 70% (95%-BI = 62–79). Complicaties van graad III of hoger traden op bij 1,2% van de patiënten. Bij 19% en 92% van de patiënten trad new onset urine-incontinentie respectievelijk erectiele disfunctie op, bij 6,5% persisterende urinaire fistels en bij 12% desobstructie. SCS heeft aanvaardbare oncologische resultaten, maar kan gepaard gaan met ernstige complicaties (urine-incontinentie, stenose en fistels).
