Why not let them rest in pieces? Grog‐temper, its provenance and social meanings of recycled ceramics in the Baltic Sea region (2900–2300 BCE)
Authors: Holmqvist Elisabeth 
Published: October 2021

AbstractCeramic recycling, that is, using discarded ceramics as raw materials in manufacturing, occurs sporadically in ceramic technologies worldwide. Adding pre‐fired, crushed ceramic fragments, known as grog or chamotte, to clay can improve the manufacturing process and product performance (e.g., thermal‐shock resistance). In ethnographic ceramic traditions, ceramic recycling also conveys various social meanings relating to identity, kinship and ancestry. However, ‘foreign’‐origin grog complicates scientific provenancing of archaeological ceramic fabrics. This study investigates the geochemical discrimination of grog and grog‐tempered Corded Ware Culture pottery (c.2900–2300 BCE), and the possible social signals produced by ceramic recycling in the Baltic Sea region.
High performance yet ethically risky? A self‐regulation perspective on the double‐edged sword effects of the performance‐oriented human resource system
Authors: Zhang Guanglei , Wang Huaying , Ma Rong , Li Mingze 
Published: October 2021

AbstractPerformance‐oriented human resource system (HRS) brings both benefits and risks to organizations. Prior studies mainly reported the positive impact of performance orientated HRS on organizational and employee performance, ignoring its negative impact on employee behavior. Based on self‐regulation theory, this paper examines the double‐edged sword effects of performance‐oriented HRS on employee outcomes. Multiwave data from a total of 253 employees indicated that perceived performance‐oriented HRS can predict employees’ concerns with performance. This system could improve their willingness for self‐development, but it may also reduce employees’ moral awareness, which increases employees’ unethical behavior. Employees’ self‐control moderates the negative effects of performance‐oriented HRS; that is, when employees’ self‐control is low, performance‐oriented HRS leads to a stronger influence on employees’ unethical behaviors through moral awareness than when it is high. The results enhance our knowledge of the effects of performance‐oriented HRS on employees’ attitudinal and behavioral outcomes and provide new insights for countering the negative effects of performance‐oriented HRS in organizational human resource practices.
The UK COVID‐19 app: The failed co‐production of a digital public service
Authors: Polzer Tobias , Goncharenko Galina 
Published: October 2021

AbstractThe COVID‐19 pandemic put governments under pressure to make radical and urgent decisions, and to implement new digital solutions to steer society and deliver public services. Our study analyzes social media discourse to understand the co‐production of a digital public service in an emergency situation. Empirically, we mobilize Twitter netnography and discourse analysis to examine citizens’ perceptions of the contact tracing app (CTA) introduced by the UK government to tackle the pandemic and save lives. Our study contributes to research on public sector accountability for digital transformations by advancing scholarly understanding of how societal concerns and public perceptions impact the co‐production of digital services. Our findings reveal a high level of public skepticism toward the app and a general distrust of the UK government among the main social challenges of the CTA's implementation. Furthermore, we evidence widespread public distress over the potential violation of democratic freedoms and misuse of the data collected by the app. Finally, we reflect on the linkages between the lack of governmental accountability and the difficulties in mitigating the expressed societal concerns, causing a corresponding resistance on the part of the public to engage in and support co‐production.

Authors: Kam Yan Ning , McKenzie Kelly , Coyle Mitchell , Bertin François‐René 
Published: October 2021

AbstractBackgroundPituitary pars intermedia dysfunction (PPID) is a common endocrinopathy of horses diagnosed with a thyrotropin‐releasing hormone (TRH) stimulation test.Hypothesis/ObjectivesDescribe the repeatability of TRH stimulation in horses with and without PPID in winter and autumn.AnimalsTwenty adult horses; 6 controls and 6 with PPID tested in autumn, 8 controls and 6 with PPID tested in winter with 3 controls and 3 with PPID tested in both seasons.MethodsThyrotropin‐releasing hormone stimulation was performed on 2 consecutive occasions, 1 week before and 1 week after the winter solstice and the autumn equinox. Blood was collected before and 30 minutes after IV injection of 1 mg of TRH. ACTH concentration was determined by a chemiluminescent assay. Repeatability and test‐retest reliability were assessed by repeated measures analysis of variance, intraclass correlation coefficient and within‐horse coefficients of variation (CV). Bland‐Altman plots were generated to visualize agreement between repetitions.ResultsIn winter, no week effect was detected on the results of the TRH simulation and the test had an excellent test‐retest reliability. In autumn, after‐TRH ACTH concentrations were significantly lower on week 2 (P = .02) and the test only had a good test‐retest reliability. There were significantly larger within‐horse CV during autumn (P = .04) and after TRH stimulation (P = .04). There were 2 misclassifications in winter and 4 in autumn.Conclusions and Clinical ImportanceThe TRH stimulation test was repeatable when performed 2 weeks apart in winter; however, in autumn, more variability in after‐TRH ACTH concentrations resulted in decreased repeatability.
‘The Pressing Question of the Hour’: Fr. Vincent McNabb O.P. & the Reception of Rerum Novarum
Authors: Finn Richard 
Published: October 2021

AbstractA study of the British reception history of Rerum Novarum between 1891 and 1919 shows the key role of Fr. Vincent McNabb OP in popularising in the Catholic press what would become the predominant interpretation of the encyclical, switching its perceived emphasis away from the defence of private property to the advocacy of an urgent redistribution of property unjustly withheld from the impoverished working classes
Robert Holcot’s Trinitarian Theology and Medieval Historiography
Authors: Slotemaker John T. 
Published: October 2021

AbstractThis paper argues that the Dominican, Robert Holcot's, Trinitarian theology is methodologically consistent with what one finds in the Franciscan theologian, William of Ockham's,Summa logicae. Both theologians, it is argued, develop a form of Trinitarian minimalism that rejects many of the developments in thirteenth-century Trinitarian theology. Further, it is argued that the traditional two-model approach to medieval Trinitarian theology, as found in Théodore de Regnon, Michael Schmaus, and Russell Friedman must be re-evaluated in light of current research.
Unum Necessarium: Gerald Vann's Unifying Thomistic Vision
Authors: Conrad Richard , Crowe Nicholas Paul 
Published: October 2021

AbstractWe note how Gerald Vann's pastoral context fired his concerns, and examine part of his output, especially his Lectorate thesis,Saint Thomas Aquinas, The Divine Pity, andThe Son's Course. He popularised insights drawn from Aquinas and Neo-Thomists, developed in conversation with his brethren, while critically welcoming other traditions and modern culture. He rooted creative thought in Thomist doctrine, and offered Aquinas's vision as an answer to prevalent forms of disintegration. Some of his ideas and expressions are ‘of their time’; his urging an ever fresh contemplation of Christ, and his approach to the Gospel ‘paradox’ of renouncing all things for God's sake, while sharing God's love for creatures, are recognized as a powerful statement of recurring Christian themes. Vann wasahead of his timein sharing widely the distinctively Thomist account of the Spirit's role in guiding our pilgrimage, working unity, and divinizing our perceptions through his Seven Gifts. In this Vann was faithful to the Thomist vision he developed in his formal studies, of the eternal Processions of the Divine Wisdom and the Holy Spirit lying behind the coming of creatures from God and, more excitingly still, lying behind our return to our Triune Archetype.
‘To Do For Our Own Age What Thomas Did For His’: Victor White OP
Authors: Weldon Clodagh 
Published: October 2021

AbstractWhen thinking about the life and theology of the English Dominican, Victor White OP (1902-1960), it is his formation at Hawkesyard which holds the key to understanding the direction of his life and work. This brief introduction sets White in the context of his day, showing how his formation created the conditions which drew him to the analytical psychologist, C.G. Jung (1875-1961), at the same time prompting his identification as a modern Thomist, an identification which gave him the framework to engage Jung's thought, and to influence the direction of theology at Blackfriars Oxford. In other words, I hope to show that White's formation at Hawkesyard is the turning point from which all else follows.

AbstractREV7 is a multifunctional protein implicated in DNA damage tolerance, cell cycle control, and gene expression, and is involved in the carcinogenesis of various human tumors. It has been reported that REV7 expression is associated with ultraviolet‐induced mutagenesis; however, the role of REV7 expression in skin cancers, including malignant melanomas, remains unclear. In the present study, we investigated the clinical and biological significance of REV7 in malignant melanoma. Levels of REV7 expression in human skin cancers were evaluated immunohistochemically. Positive expression of REV7 was frequently observed in malignant melanomas, as well as in squamous cell carcinomas and basal cell carcinomas. Enhanced immunoreactivity to REV7 was closely linked with cell proliferation assessed by Ki‐67 labeling indexes in the three skin cancers, and was related with tumor thickness in malignant melanomas. REV7 depletion in malignant melanoma cells MEWO and G361 suppressed cell proliferation, migration, and invasion abilities. REV7 depletion also affected the expression of intracellular signaling molecules AKT and ERK in MEWO cells, resulting in downregulation of ERK signal activation. In addition, REV7 depletion facilitated sensitivity to cisplatin, but not to dacarbazine, in MEWO cells. Our results suggest that REV7 expression correlates with disease progression of malignant melanoma.
Productivity effects of processing and ordinary export market entry: A time‐varying treatments approach
Authors: Girma Sourafel , Görg Holger 
Published: October 2021

AbstractChina's policy of encouraging export processing has been the topic of much discussion in the academic literature and policy debate. We use a recently developed econometric approach that allows for time varying “treatments” and estimate economically and statistically significant positive causal effects of entering into export processing and ordinary export markets on subsequent firm level productivity. These productivity effects are shown to be larger than those accruing to firms who enter into ordinary exporting. Interestingly, the estimation of quantile treatment effects shows that the positive effects do not accrue similarly to all types of firms, but are strongest for those at the low to medium end of the distribution of the productivity variable. We also find that export processors gain more when entering the industrialised North rather than the South, while this does not appear to matter much for ordinary exporting.
Effectiveness of broad‐spectrum antiseptics in production of disinfected maggots of Lucilia sericata for use in wound debridement therapy
Authors: Taleb Meriem 
Published: October 2021

AbstractThe establishment of low‐cost, effective, safe and practical methods is necessary to increase the use of larval therapy in wound care. Although studies on external disinfection of calliphorid eggs have been reported, many studies lack data on the effect of disinfection on egg viability and the microorganisms found before disinfection. Therefore, the main objective of this study was to compare three antiseptic solutions, that is, chlorhexidine (5%), Dakin's solution (0.5% NaOCl) and povidone‐iodine (10%), in terms of their ability to disinfect Lucilia sericata eggs. Egg viability after disinfection and microorganisms present on the eggs and larvae before and after treatment were also examined. None of the antiseptics had a significant effect on egg viability. Disinfection of L. sericata eggs with 0.5% NaOCl was the best method, as sterility tests showed no contamination. Escherichia coli, Bacillus subtilis and Proteus mirabilis were present in all cultures isolated from the non‐disinfected eggs and larvae, while Enterococcus faecium, Enterococcus faecalis, Morganella morganii, Corynebacterium spp. and Providencia stuartii were isolated from more than half of the same cultures. Sterility testing of medicinal maggots after disinfection is crucial to prevent secondary infections and achieve a positive therapeutic outcome.
Mitogenomes provide new insights into the evolutionary history of Prodiamesinae (Diptera: Chironomidae)

Published: October 2021

AbstractEvolutionary analysis of Prodiamesinae has long been impeded by lack of information, and its phylogenetic relationship with Orthocladiinae remains questionable. Here, ten complete mitochondrial genomes (mitogenomes) of Orthocladiinae sensu lato were newly sequenced, including three Prodiamesinae species and seven Orthocladiinae species. Coupled with published mitogenomes, a total of 12 mitogenomes of Orthocladiinae sensu lato were selected for a comparative mitogenomic analysis and phylogenetic reconstruction. Mitogenomes of Orthocladiinae sensu lato are conserved in structure, and all genes arrange the same gene order as the ancestral insect mitogenome. Nucleotide composition is highly biased, and the control region displayed the highest A + T content. All protein‐coding genes are under purifying selection, and the ATP8 evolves at the fastest rate. In addition, the mitogenomes of Orthocladiinae sensu lato are highly conserved, and they are practically useful for phylogenetic inference, suggesting a re‐classification of Orthocladiinae by sinking Prodiamesinae as a subgroup of Orthocladiinae.
The Influence of the Earth’s Oblateness on the Energy Integral and Some Characteristics of a Spacecraft’s Orbit
Authors: Ivashkin V. V. 
Published: October 2021

Abstract
Taking into account the oblateness of the Earth with the help of the second zonal harmonic of the potential of the Earth’s gravitational field modifies the integral of the energy of near-Earth motion in comparison with the Keplerian model of analysis. On the basis of this integral, an explicit analytical structure of the change in the main orbital parameter—the Keplerian energy constant—is obtained. This method of taking into account the oblateness of the Earth also makes it possible to estimate the correction, in comparison with the standard unperturbed analysis, in the departure speed of a spacecraft from the near-Earth waiting orbit when flying to the Moon or another planet.

Authors: Karatunov M. O. , Baranov A. A. , Golikov A. R. 
Published: October 2021

Abstract
A method for assessing the probability of collision of two observed space objects in near-earth space is proposed. The solution is based on the method of statistical modeling, which made it possible to take into account the shape and orientation of approaching objects. The developed method provides for the automatic stop of calculations when the required accuracy and reliability of the solution is achieved. An analysis of existing approaches to assessing the probability of collision is given. A calculation was made for the real approach of the vehicles CHINASAT-20 and SHIJIAN-17.

ObjectiveHypothermia is believed to affect more than half of Ethiopian neonates. The goal of this study is to determine risk factors for newborn hypothermia in neonates admitted to public hospitals in the east Wollega zone of western Ethiopia’s neonatal intensive care unit.DesignUnmatched case–control study using neonates admitted to the intensive care unit.SettingNeonatal intensive care units at public hospitals in western Ethiopia.PatientsNeonates admitted to intensive care units.Main outcomesThe cases were all neonates with hypothermia (less than 36.5°C) and the controls were all neonates with a body temperature of greater or equal to 36.5°C when admitted to the neonatal intensive care unit for other reasons.ResultsThe study involved the participation of 73 cases and 146 controls. The study found that delayed breastfeeding initiation after 1 hour (adjusted OR (AOR)=3.72; 95% CI: 1.39 to 10.00), admission weight less than 2500 g (AOR=3.43; 95% CI: 1.18 to 9.97), cardiopulmonary resuscitation at birth (AOR=3.42; 95% CI: 1.16 to 10.10.08), lack of immediate skin-to-skin contact with their mother (AOR=4.54; 95% CI: 1.75 to 11.81), night-time delivery (AOR=6.63; 95% CI: 2.23 to 19.77) and not wearing a cap (AOR=2.98; 95% CI: 1.09 to 8.15) were all associated with newborn hypothermia.ConclusionsNeonatal hypothermia was associated with obstetric, neonatal and healthcare provider factors. As a result, special consideration should be given to the thermal care of low birthweight neonates and the implementation of warm-chain principles with low-cost thermal protection in Ethiopian public health facilities.

BackgroundBone fractures are a common reason for children and adolescents to seek evaluation in the ED. Little is known about the pain experienced after cast immobilisation and discharge from the ED and its optimal management. We aimed to investigate the administration of pharmacological analgesia in the first days after cast immobilisation and to identify possible influencing variables.MethodsA prospective observational cross-sectional study was conducted at the ED of the children’s hospital, Institute for Maternal and Child Health of Trieste, Italy, from October 2019 to June 2020. Patients aged 0–17 years with bone fractures were included. The primary outcome was the administration of analgesia during the 10 days following discharge, while secondary outcomes were the associated variables, including age, gender, fracture type and location, the mean limitation in usual activities and the frequency of re-evaluation at the ED for pain. Data were recorded through a questionnaire, completed by caregivers and collected by the researchers mainly through a telephone interview. The primary endpoint was evaluated as the ratio between the number of children who took at least one analgesic dose and the total enrolled children, while Χ2or Fisher’s exact tests were used to assess secondary outcomes.ResultsDuring the study period, 213 patients, mean age 10 years (IQR: 8–13), were enrolled. Among them, 137 (64.3%) did not take any analgesic during follow-up. Among children who were administered analgesia, 22 (28.9%) received it only on the first day, and 47 (61.8%) for less than 5 days. One hundred and sixty one patients (75.6%) did not report any limitation in usual activities because of pain. The administration of analgesia was not related to the child’s age, gender or fracture site. Displaced fractures were associated with significantly more frequent analgesia being taken (OR 5.5, 95% CI 1.4 to 21.0).ConclusionAlthough some studies recommend scheduled analgesic treatment after discharge for bone fractures, this study would suggest analgesia on demand in children with non-displaced fractures, limiting scheduled analgesia to children with displaced fractures.

Published: October 2021

AbstractThe case of a 31 year old male presenting as an emergency with a recurrent colonic volvulus is described. A chest X-ray on admission to hospital showed the presence of hepato-diaphragmatic interposition of the colon, Chilaiditi’s Sign, which is known to be a risk factor for colonic volvulus. This is only the fourth reported case of colonic volvulus in association with Chilaiditi’s Syndrome and the first with recurrent colonic volvulus. The optimal treatment for recurrent volvulus in patients with risk factors such as Chilaiditi’s Syndrome or megacolon is also discussed.

Authors: Matthews Jon J , Mercer Stuart J 
Published: October 2021

AbstractDuring the second Gulf War in 2003. the Primary Casualty Receiving facility onboard R.F.A. Argus treated thirty six patients with injuries sustained in the conflict, including thirty Iraqi enemy prisoners of war and displaced persons. Their injuries and operative management are reported. Eighteen casualties sustained fragmentation injuries, six casualties sustained gunshot wounds and seven casualties suffered a combination of both. In addition to penetrating missile injuries five casualties from road traffic accidents were treated. All wounds were managed following the established principles of war surgery. The extremities were involved in twenty eight patients (78%) including nine open, multifragmented long bone fractures which were managed with external skeletal fixators. Two laparotomies and one thoracotomy were performed. The average duration of surgery was one hundred and thirty two minutes with the longest procedure lasting for six hours and ten minutes. This was the first time that the Primary Casualty Receiving Facility had been used to surgically manage war casualties and it fulfilled this role to good effect.
