Contact zones: Multispecies scholarship through Imperial Eyes
Authors: Wilson Helen F
Published: July 2019

The contact zone is described as the space of imperial encounter. Against a backdrop of work that has used Mary Louise Pratt's concept of the contact zone to examine culture-making, and destabilize normative understandings of division, distinction, and bordering, the paper interrogates the value of utilizing the concept in multispecies contexts. To do so, the paper considers the relationship between the contact zone and the concept of encounter, noting how they overlap and depart as approaches to questioning embodied difference, colonial histories, and immanent potential. Turning to the BBC documentary series Blue Planet II, the paper uses the concept of the contact zone and discourse analysis to examine its dominant ideas, frontiers of difference, and the means through which alternative geographies are both foreclosed and enabled. It demonstrates how the concept of the contact zone can draw attention to the ocean as the documentary's site of production, where different forms of knowledge, technology, people, elements, and non-human life grapple with each other in conditions of uneven power. In moving between narrative and oceanic contact zones, the paper raises questions about practices of knowledge-making, uneven structures of power, and decipherability, to demonstrate what can be gained from staying with the postcolonial framing of the contact zone as a critical tool of analysis in multispecies scholarship.
Clinical meaning of PROMIS pain domains for children with sickle cell disease
Authors: Singh Ashima , Panepinto Julie A.
Published: July 2019

The Patient Reported Outcomes Measurement Information System (PROMIS) pain interference and pain behavior domains are valid and reliable for children with sickle cell disease (SCD). However, clinical interpretation of the scores is unknown. The objective of this study was to determine the clinical meaning of PROMIS pain scores for children with SCD. We used 2 approaches to determine clinical meaning: dichotomization of item responses and T-score ranges. T-score ranges determined thresholds for no/mild, moderate, and severe pain. We compared the proportion of patients who needed pain medications among pain severity groups using χ2/Fisher’s exact tests. The study included 117 children (mean age, 11.5 years [standard deviation, 2.9 years]). Using the dichotomization approach, 43 children had pain interference T-scores ≤48 reflecting minimal pain, and 30 children had T-scores >60 reflecting substantial pain. For pain behavior, 34 children had T-scores ≤41 reflecting minimal problems, and 23 patients had T-scores >57 reflecting substantial problems with pain. Using T-score ranges, clinical thresholds of no/mild and severe pain interference were determined as ≤48.3 and >63.6, respectively. The thresholds for no/mild and severe pain behavior were ≤41.3 and >57.3, respectively. Overall, the proportion of patients who took pain medications was significantly different among those with no/mild, moderate, and severe pain as identified by pain interference (P = .002) and pain behavior domains (P = .0113). We identified T-scores for PROMIS pain domains that facilitate clinical interpretation and provide necessary information for PROMIS users in a clinical setting.

Sensitive tools are needed to accurately establish the diagnosis of tuberculosis (TB) at death, especially in low-income countries. The objective of this study was to evaluate the burden of TB in a series of patients who died in a tertiary referral hospital in sub-Saharan Africa using an in-house real time PCR (TB-PCR) and the Xpert MTB/RIF Ultra (Xpert Ultra) assay.

Complete diagnostic autopsies were performed in a series of 223 deaths (56.5% being HIV-positive), including 54 children, 57 maternal deaths and 112 other adults occurring at the Maputo Central Hospital, Mozambique. TB-PCR was performed in all lung, cerebrospinal fluid and central nervous system samples in HIV-positive patients. All samples positive for TB-PCR or showing histological findings suggestive of TB were analysed with the Xpert Ultra assay.

TB was identified as the cause of death in 31 patients: three out of 54 (6%) children, five out of 57 (9%)maternal deaths and 23 out of 112 (21%) other adults. The sensitivity of the main clinical diagnosis to detect TB as the cause of death was 19.4% (95% CI 7.5–37.5) and the specificity was 97.4% (94.0–99.1) compared to autopsy findings. Concomitant TB (TB disease in a patient dying of other causes) was found in 31 additional cases. Xpert Ultra helped to identify 15 cases of concomitant TB. In 18 patients,Mycobacterium tuberculosisDNA was identified by TB-PCR and Xpert Ultra in the absence of histological TB lesions. Overall, 62 (27.8%) cases had TB disease at death and 80 (35.9%) had TB findings.

The use of highly sensitive, easy to perform molecular tests in complete diagnostic autopsies may contribute to identifying TB cases at death that would have otherwise been missed. Routine use of these tools in certain diagnostic algorithms for hospitalised patients needs to be considered. Clinical diagnosis showed poor sensitivity for the diagnosis of TB at death.
A solution to prevent secondary flow in adherent cell cultures
Authors: Szaraz Peter , Librach Matthew , Mander Poonam , Hoseini Banafshe , Librach Max , Iqbal Farwah , Librach Clifford
Published: July 2019

High quality cell cultures require reliable laboratory practices. Today's small-scale in vitro cell culture format is dominated by circular topology vessels, with the inherent disadvantage of secondary flow induced each time the cell cultures are repositioned. The secondary flow generates uneven sedimentation and adherence that negatively impacts cell culture quality. Here we show a modification of the circular culture vessel that abrogates these disturbances. Cell culture wells were augmented with a central column to diminish secondary flow. Human carcinoma cell lines (BeWo, JEG-3), mesenchymal stem cells [human umbilical cord perivascular cells (HUCPVC)] and mouse embryonic fibroblasts (MEF) were cultured in both column-augmented and regular culture wells. Human carcinoma cell cultures showed even cell densities and significantly more viable cells in column-augmented vessels. In FTM HUCPVC cultures, cell surface MSC marker (CD90, CD105) expression and cell differentiation-related gene expression patterns were significantly more homogeneous in column-augmented vessels. MEF cells in column-augmented culture vessels showed a more consistent expression of IGF-1. Column-augmented cell culture vessels significantly improve the homogeneity of adherent cell cultures by mitigating the adverse effect of the secondary flow.

Underwater hearing in sea snakes (Hydrophiinae): first evidence of auditory evoked potential thresholds
Authors: Chapuis Lucille , Kerr Caroline C. , Collin Shaun P. , Hart Nathan S. , Sanders Kate L.
Published: July 2019

The viviparous sea snakes (Hydrophiinae) are a secondarily aquatic radiation of more than 60 species that possess many phenotypic adaptations to marine life. However, virtually nothing is known of the role and sensitivity of hearing in sea snakes. This study investigated the hearing sensitivity of the fully marine sea snake Hydrophis stokesii by measuring auditory evoked potential (AEP) audiograms for two individuals. AEPs were recorded from 40 Hz (the lowest frequency tested) up to 600 Hz, with a peak in sensitivity identified at 60 Hz (163.5 dB re. 1 µPa or 123 dB re. 1 µm s−2). Our data suggest that sea snakes are sensitive to low-frequency sounds but have relatively low sensitivity compared with bony fishes and marine turtles. Additional studies are required to understand the role of sound in sea snake life history and further assess these species' vulnerability to anthropogenic noise.
Relative prolixity in journals with different citation impact values: an evidence-based scientific writing assessment
Authors: Nascimento Gyzelle P.V. , Moreira Daniel C. , Welker Alexis F.
Published: July 2019

Background: Scientific writing guidelines recommend that a scientific text should be straightforward, without prolixity, and informative, without obscurity. However, the extent to which researchers follow these recommendations is unknown. Considering that the most cited journals provide more detailed instructions for authors, we aimed to investigate the degree of relative prolixity (i.e., length versus amount of information) among journals with different citation impact scores.

Methods: We analyzed journals whose articles follow the classic Introduction, Method, Results, and Discussion structure, written in English and with a CiteScore value ≥ 0.01 classified in the ‘Pharmaceutical Science’ area. Relative prolixity was calculated as the ratio between the number of characters and the number of citations contained in the introductory section of original articles. Additionally, we collected the number of paragraphs and words.

Results: The number of characters, words and citations in the Introduction section were significantly higher in the journals with higher CiteScore values. The median number of paragraphs in the Introduction was not affected by the citation impact of the journals. The degree of relative prolixity in the Introduction section of the articles was negatively correlated with the CiteScore values.

Conclusions: Articles published in journals with higher CiteScore values have lower degrees of relative prolixity (i.e., shorter texts to transmit a certain amount of information) and obscurity.

Published: July 2019

The article estimate some aspects of the functioning of cryptocurrency, as a relatively new financial market instrument, the main participants in this market segment, cryptocurrency exchanges, taking into account key criteria: accessibility, mobility, operational efficiency. The aspects of regulation at the world and national levels are investigated.

The authors give an assessment of the mechanism for regulating cryptocurrencies in separate countries ,which recognize this instrument and actively regulate it (Ar-gentina, Canada, Japan, Malazia, Switzerland),as well as countries, which reject (Vi-etnam) or just tolerate cryptocurrency, but do not have the regulatory framework for it use.

Obviously, cryptocurrency is a relatively new instrument of the financial market, but its value not depend with amount of labour invested, as it is traditionally charac-teristic for conventional goods and services.

The research shows that bitcoin still remains the most widespread type between other different kinds of cryptocurrencies.

A significant aspect of cryptocurrencies functioning is their regulation. In our country there is no legislative certainty yet, but some steps have been made in this di-rection.

In the long term, cryptocurrencies will be regulated at the international level, and the emphasis will be on preventing the use of their illegal financial transactions and for money laundering.

Published: July 2019

As condições de umidade relativa e temperatura determinarão mudanças na manutenção da qualidade do produto até que o produto atinja o teor de água em equilíbrio, sendo diretamente relacionado à secagem e ao armazenamento. Assim, objetivou-se neste estudo especificar as isotermas de dessorção da água em sementes de trigo e obter os valores do calor isostérico de dessorção em função do teor de água de equilíbrio. Os dados das isotermas de dessorção do teor de água das sementes de trigo foram obtidos pelo método estático gravimétrico, em cinco temperaturas (5, 10, 15, 25 e 40°C), e pela atividade de água entre 0,204 e 0,7567. Foram utilizados cinco modelos matemáticos, Chung-Pfost, Copace, Sigma-Copace, GAB e Sabbah, para descrever os dados experimentais obtidos. O teor de água de equilíbrio das sementes de trigo se reduz com o aumento da temperatura a um teor de água constante. O modelo Chung-Pfost é o que melhor representa as isotermas de dessorção da água das sementes de trigo para faixa de atividade de água estudada. O calor isostérico de dessorção das sementes de trigo aumenta com a redução do teor de água, variando de 2.602,85 a 4.280,60 kJ.kg-1; para a faixa de teor de água estudada de 9,42 a 17,92% (b.s.), o calor isostérico permite determinar o ponto final de secagem e a quantidade mínima de energia requerida para a secagem do alimento.

Background and Aim: Testis and epididymis are male reproductive organs that play an important role in spermatogenesis. These two organs are rich in the content of hormones and other molecules needed in the process of spermatogenesis which affect the quality of the spermatozoa. The objective of this study was to examine the effect of the administration of epididymis and testicular extracts and their combination on testosterone, pituitary adenylate cyclase-activating polypeptide (PACAP), and protamine 1 (PRM1) concentrations in the serum of male chicken.

Materials and Methods: Twenty male chickens (broiler strain Cp707), aged 3 weeks and weighing 800-1000 g, were randomly divided into four different groups including a control group (T0) = injected with 1 ml normal saline and treatment groups: T1 = injected with 1 ml epididymis extract, T2 = injected with 1 ml testicular extract, and T3 = injected with a combination of 1 ml epididymis + 1 ml testicular extract. The experiment was conducted for 13 days and at the end of the study (day 14), the chickens were sacrificed to obtain the serum. Furthermore, the concentrations of testosterone, PACAP, and PRM1 were then measured by using an enzyme-linked immunosorbent assay technique.

Results: The concentrations of PACAP and PRM1 did not show a significant difference between treatment groups (T1, T2, and T3) and control group (T0) (p>0.05). However, the concentration of testosterone showed a significantly higher difference in a group injected with a combination of 1 ml epididymis and 1 ml testicular extracts (T3) compared to the control group (T0) (p<0.05).

Conclusion: The administration of epididymis and testicular extracts and their combination did not affect the increase of PACAP and PRM1 concentration. However, a combination of these extracts significantly affects the increase of testosterone concentration in the serum of male chicken.

Использование кластерного анализа химического состава растений в хемосистематике
Authors: Круглов Д. С.
Published: July 2019

В настоящей работе был проведен кластерный анализ микроэлементного состава растений родов Pulmonaria, Vaccinium, Oxycoccum и компонентного спектра эфирного масла, полученного из растений родаFilipendula. Были построены дендрограммы распределения исследуемых растений по кластерам по их микроэлементному спектру и компонентному составу эфирных масел. В результате было установлено, что и микроэлементный состав растения так же, как и компонентный состав эфирного масла являются видоспецифичными имогут использоваться в хемосистематике. Распределение растений по кластерам коррелирует c систематическимположением исследуемых видов по общепринятым в систематике морфологическим признакам. Таким образом,применение кластерного анализа позволяет реализовать технологию «Fingerprinting» и использовать микроэлементный спектр растения так же, как и компонентный спектр продуцируемого эфирного масла в качестве спектров-маркеров в задачах систематики.

В селитебной зоне, расположенной вблизи (50–150 м) от промышленно складированной пустой породы, степень загрязненности почвы также имеет высокие показатели. Эти факторы крайне опасны для населения, так как растения, растущие на отвалах, и растениеводческая продукция и передают в пищевые цепи мышьяк.Выявлено, что в начале вегетации уровень загрязненности мышьяком растений в целом имеет низкие показатели,а степень поглощения данного элемента по коэффициенту накопления позволяет отнести его к группе очень слабого накопления и захвата. Совокупная оценка накопления мышьяка по абсолютному содержанию в растениях изразных зон контаминации выявила значимые отличия между техногенной и фоновой зонами (Н = 7,05, p = 0,008).

Even though the corrosion of steel in concrete is very well described, the corrosion processes in lime environment studied very rarely. This environment is obviously also basic and its pH decreases in time, but the obtained results indicate important differences in behaviour of these two systems. Corrosion response of carbon steel, zinc platted steel, copper, brass and lead placed in lime mortar was studied by help of SEM microscopy.

Published: July 2019

This article deals with the development of lightweight UHPC facade panel which also can serve as an LED display. Combining both functions into one gives the potential ability to create a LED display on the facade of the building. The article describes the experiences of the development and production of a small-format prototype facade panel, including the installation of LEDs and their electrical connection. The result of the research is the prototype of a 16mm thick small-format lightweight facade panel with a LED display for displaying text on two parallel lines. Thanks to the waffle lightening, the total material and weight savings are approximately 58% compared with the full cross section.
CARACTERÍSTICAS INSTITUCIONAIS DOS PAÍSES E PRÁTICAS DE EVIDENCIAÇÃO DAS PROVISÕES E PASSIVOS CONTINGENTES AMBIENTAIS: UM ESTUDO INTERNACIONAL
Authors: Prado Thiago Alberto dos Reis , Ribeiro Maísa de Souza , Moraes Marcelo Botelho de
Published: July 2019

Esta pesquisa objetiva investigar a relação entre as características institucionais dos países de origem das empresas, que adotam IFRS, e a evidenciação das provisões e passivos contingentes ambientais. Com base na Teoria Institucional, espera-se que as características institucionais dos países exerçam pressões sobre as práticas de evidenciação, indo de encontro aos objetivos do IASB de comparabilidade em nível global. A pesquisa tem como amostra 614 observações de 123 companhias do Brasil, Canadá, Reino Unido, França, Alemanha, Austrália e China, de setores que exploram o meio ambiente com mais intensidade. O período de análise compreende os anos de 2011 a 2015. Como metodologia, empregou-se análise fatorial e regressões com modelos de dados em painel. Os resultados obtidos mostraram que o disclosure de provisões ambientais está relacionado com o fator construído pelas variáveis de interesse dos sistemas político, financeiro e cultural do país de origem das empresas. No entanto, em relação a passivos contingentes ambientais, não foi encontrada relação estatisticamente significativa com o fator. As evidências de isomorfismo coercitivo e mimético encontradas permitem inferir que a evidenciação de provisões ambientais está relacionada com fatores múltiplos e conflitantes com o escopo de comparabilidade do IASB, o que prejudica este objetivo e sinaliza a não comparabilidade. A principal conclusão deste trabalho é a de que, apesar de existirem pressões normativas para a existência da comparabilidade, há pressões institucionais conflitantes de outros atores sociais, de caráter coercitivo e mimético, fazendo com que as empresas, em busca de legitimidade, conduzam suas práticas de reporte estrategicamente, indo de encontro aos objetivos do IASB.

The purpose of this study was to examine the effects of budget participation in the sharing of vertical information and in the performance of controllers with budgetary responsibility in companies operating in Brazil, observing the effects of variables antecedent to the budget process, related to actions and behavior of the leader. In order to respond to the objective, a descriptive research was carried out by means of a survey and a quantitative approach to the data analysis, based on a sample of 316 respondents who perform the role of controller, manager or controllership coordinator.The theoretical relations investigated in this research were tested using the modeling technique of structural equations. The results showed a strong relationship between leadership style and incentive of budget participation. Positive, statistically significant relationship was found between encouraging participation and budget participation, as well as between budget participation and information sharing. These results reveal that the leader’s incentive for controllers to participate in the budget processes in their organizations constitutes an important antecedent for the budget participation and its consequent effects on the managerial performance. The positive influence of vertical information sharing on performance reveals that this condition is a determinant for a better managerial performance of the controllers participating in the research. It is concluded that the antecedents of budget participation, related to the leadership style and the incentive to participate, contribute to the understanding of the budget configuration adopted by the companies and its effects on the managerial performance of controllers, which is enhanced whenthe occurrence ofvertical information sharing.

Bamboo is a natural bio-composite material that is both tough and possesses excellent mechanical properties. Its delicate structure and fiber arrangements play an important role in the mechanical properties and the fracture performance of bamboo. In this study, the fracture behaviors of bamboo due to tensile strength and bending were investigated using synchrotron radiation micro-computed tomography and environmental scanning electron microscopy (ESEM). Both tension and bending tests revealed that fibers are the key factors for bearing extra load and impeding crack propagation. Crack paths were found to be different in bamboo strips with different fiber percentages, and the interface between pulled-out fiber bundles and fiber break (in helix breaks and shearing break) was observed to be typical fracture characteristics in tension. Moreover, advanced micro-matrix cracking, interface debonding, fiber bundle bridging and the splitting of cell wall layers were found to be important fracture characteristics in bending. Both in tension and bending, a reasonably weak interface appeared to be beneficial for improving fracture toughness of fiber-reinforced bamboo. Thus, it is clear that “fiber bridging” mechanisms and “shear-lag theory” are well exhibited in bamboo.
Artificially aged spruce and beech wood surfaces reactivated using FE-DBD atmospheric plasma

Although weathering is usually carried out in outdoor conditions, even ageing in indoor conditions can cause significant changes to wood surfaces. We found these to notably impact wetting and coatability of surfaces of common beech (Fagus sylvatica L.) and Norway spruce [Picea abies (L.) Karst.] wood. These effects were well overcome and the surfaces reactivated using a novel kind of a plasma device. On both kinds of wood, ageing caused significant changes in their colour, opening of pits and cell wall destruction. Infrared spectra indicated a significant decrease of aromatic lignin and production of non-conjugated carbonyl groups. Surface free energies and spreading kinetics varied much upon this kind of ageing. In beech, pull-off strengths for a commercial waterborne wood coating slightly decreased for longer exposure times. For the reactivation of wood surfaces, we employed a novel approach using a floating electrode dielectric barrier discharge (FE-DBD) plasma, which had not been done on wood before. Similar to other plasma techniques, the surface free energy (SFE) increased after treatment. On beech wood, the plasma treatment (PT) led to higher pull-off strengths of the waterborne coating. On spruce wood, the coating mostly showed cohesive failures after ageing, and thus the PTs showed less improvements.

Palaepaphos: Unlocking the Landscape Context of the Sanctuary of the Cypriot Goddess
Authors: Iacovou Maria
Published: July 2019

The cult centre of Palaepaphos was in continuous use since the construction of its megalithic temenos in the Late Bronze Age, but the new political role which the sanctuary was made to perform in the Hellenistic and Roman periods has supressed its original identity. From the 3rd c. BC, when the citystates of the island were abolished by Ptolemy Soter, to the end of the 4th c. AD, when pilgrim visitations and state-endorsed festivals were gradually abandoned under the growing impact of Christianity, the abode of the Cypriot goddess served the colonial politics of the Ptolemaic kingdom and the Roman Empire, respectively. The Palaepaphos Urban Landscape Project (PULP) has shown that the recovery of the sanctuary’s millennium-long primary role depends on the recovery of the almost invisible landscape of its founding polity and the region’s associated settlement structure. With the use of geospatial analyses and advanced documentation and imaging technologies, PULP has been building a diachronic model of the urban structure of the ancient polity and a site distribution model of the Paphos hydrological basin. Current results have unlocked the significance of the sanctuary’s spatial location in relation to a long-lost gateway to the sea that was the foundation kernel of Ancient Paphos.
Transformative Impact: The Environmental Significance of Religious Conversions
Authors: Nitsche Martin
Published: July 2019

This paper concentrates on the transformative impact of religious conversions. I understand religious conversions here as all individual spiritual transformations that either create an essentially new religious experience or substantially intensify an existing religiosity. The transformative impact of these transformations consists not only in modifying life perspectives or values, but also (and more substantially) in altering the very structure of personal experience. They can even bring significant changes in the phenomenal character of individual life-worlds, which are then experienced as perceived “differently”. This reflects on the possibilities the phenomenological method possesses to describe (and understand) these changes, and mainly discusses the applicability of Husserl’s analyses in Ideas 2 of the double constitution of body. On this basis, I suggest an explanatory model of transformative localizing/layering.
Net Neutrality and Mobile App Innovation in Denmark and Netherlands 2010–2016
Authors: Layton Roslyn
Published: July 2019

Net neutrality or “Open Internet” rulemaking has been ongoing for more than a decade. Some 50 nations have adopted formal rules including the US (then repealed), the European Union, India, and many countries in Latin America. Among other arguments, it is asserted that net neutrality rules are necessary for application innovation. While the focus for policymakers has largely been to make rules, there is less attention on how to measure the impact of such rules and how well they achieve their innovation goals. The article summaries a specific research investigation to what degree the introduction of rules in a given country stimulates innovation in that country’s mobile app ecosystem. The focus in on mobile networks because it allowed the most consistent data across countries. The study covered 53 countries, their net neutrality policies (or lack thereof), and the results to the respective mobile application ecosystems of the countries adopting rules between the period of 2010–2016. This investigation tests the proposition that countries which adopt net neutrality rules should experience an increase in mobile app development innovation within their national economy. To test this, a statistical methodology was developed based upon measuring the number of locally developed mobile apps in the country for relevant periods before and after rules are imposed and the corresponding app downloads, usage, and revenue. Measurement was conducted with two independent toolsets and adjusted for the sophistication and penetration of advanced mobile networks in the country. To make more meaningful comparisons and avoid inevitable heterogeneity across the countries, the investigation focuses on two similar countries with different rules, Denmark with soft rules (self-regulation) and Netherlands with hard rules (legislation). The study reviewed the leading theories of innovation as well as the foundational papers in net neutrality to explain the observed discrepancies. The research finds significant statistical support for “soft” net neutrality measures adopted on a voluntary basis. Hard rules adopted through legislation and regulation were not associated with greater mobile app development for the given country. Denmark increased in local mobile app development while Netherlands decreased. Additionally, the explosion of mobile apps from countries with no net neutrality rules and the general dearth of mobile apps from countries which have had hard rules for years runs counter to expected results. This suggests that policymakers revisit their assumptions and expectations for net neutrality policy.
Ein „großer Wurf"? Gaius trifft Demosthenes
Authors: Scheibelreiter Philipp
Published: July 2019

A "lucky strike"? Gaius meets Demosthenes. In D. 50,16,233,2 Gaius explains the expression telum (missile). As the fragment derives from his commentary on the twelve tables, the majority of modern scholars tends to refer this to 12 Tab. 8,12–13, which deals with the justified killing of the armed thief. But regarding the context, it seems to be more reasonable to connect the fragment with 12 Tab. 8,24a (which deals with unintended killing with a spear). This interpretation can be supported by the fact that one passage of the commentary shows great similarities with an old Athenian law that at least can be ascribed to Solon and that Gaius could have cited as he did on other occasions in his commentary.
Scaevola D. 32,37,3: Fideicommissum a debitore oder a donatario relictum?
Authors: Kleňová Veronika
Published: July 2019

Scaevola D. 32,37,3: Fideicommissum a debitore or a donatario relictum? Classical Roman law did not know revocation of a gift. Thus, the donation in D. 32,37,3 is neither a revocable gift nor a donatio mortis causa. On the other hand, the son could be burdened with a fideicom-missum because he was debtor of the deceased. The relation between his obligation and the fideicommissum is the key to understand Scaevolas decision.
