A fundamental aspect of symbiotic relationships is host specificity, ranging from extreme specialists associated with only a single host species to generalists associated with many different species. Although symbionts with limited dispersal abilities are typically host specialists, some are known to associate with multiple hosts, but our understanding of the causes and consequences of this variation is limited.

The survey presented in this work investigates emerging markets for data and is the third of its kind, providing a deeper understanding of this emerging type of market. The findings indicate that data providers focus on limited business models and that data remains individualized and differentiated. Nevertheless, a trend towards commoditization for certain types of data can be foreseen, which allows an outlook to further developments in this area.

Since its conception in the mid 1950s, artificial intelligence with its great ambition to understand and emulate intelligence in natural and artificial environments alike is now a truly multidisciplinary field that reaches out and is inspired by a great diversity of other fields. Rapid advances in research and technology in various fields have created environments into which artificial intelligence could embed itself naturally and comfortably. Neuroscience with its desire to understand nervous systems of biological organisms and systems biology with its longing to comprehend, holistically, the multitude of complex interactions in biological systems are two such fields. They target ideals artificial intelligence has dreamt about for a long time including the computer simulation of an entire biological brain or the creation of new life forms from manipulations of cellular and genetic information in the laboratory. The scope for artificial intelligence in neuroscience and systems biology is extremely wide. This article investigates the standing of artificial intelligence in relation to neuroscience and systems biology and provides an outlook at new and exciting challenges for artificial intelligence in these fields. These challenges include, but are not necessarily limited to, the ability to learn from other projects and to be inventive, to understand the potential and exploit novel computing paradigms and environments, to specify and adhere to stringent standards and robust statistical frameworks, to be integrative, and to embrace openness principles.

Over the past decade, considerable investment has been made in acquiring knowledge about in-sewer processes, with the objective of developing new analytical tools to predict the performance of these systems. A wide variety of these tools have emerged, from simple aggregated conceptual models of entire systems, to very detailed physically based relationships for particular processes such as suspended transport. The major investors in this research have been determined to produce commercial models which will form part of integrated system analysis suites of software for use in the formulation of holistic and optimum managerial methods for wastewater systems. Unfortunately, sewer processes are extremely complex, and the very limited investment, when compared proportionately with that made in hydrological and hydraulic analysis over previous decades, has produced apparently gaps in underlying knowledge which are not generally acknowledged. This paper reviews the current position with regard to sewer process modelling, highlighting areas where knowledge is still deficient, and where new opportunities and limitations are emerging.

The paper examines the conceptual role of the insolvency (bankruptcy) procedure and the emerging trend towards the dominance of this legal mechanism over other (basic) legal categories. Three key categories are given as examples: the institute of non-interference in private affairs, which in the opposite case is transformed into intervention; the institute of limited liability of the founder (participant) and their legal entity, which presupposes a clear separation of the property masses of these subjects; and the institute of limitation period. It is proved that the bankruptcy procedure modifies the perception of the mentioned categories. Intervention becomes acceptable, which finds expression, for example, in the admissibility of challenging transactions and analyzing the debtor’s economic activities. The boundaries of the assets of a legal entity and an individual are blurred out in the context of the institution of subsidiary liability in bankruptcy. Only the statute of limitations, due to current court practice, is still subject to fewer changes, which are nevertheless present.The author concludes that it is unacceptable to consider the institution of bankruptcy as an instrument of unlimited suppression of other legal structures in favor of the interests of the creditor community. An attempt has been made to demonstrate that the legal essence of the institution of insolvency is much broader than is commonly believed. This, in turn, explains the inadmissibility and danger of perceiving bankruptcy proceedings as a kind of «sacred» legal phenomenon.

In multiple indicator-dilution experiments, transvascular passage of a permeating indicator is conventionally derived from the up-slope separation of the curve of the permeating indicator from that of a vascular reference and is expressed as the extraction (Ec). Extraction may be limited by the barrier (barrier-limited distribution). It may be limited by the volume of distribution accessible to it; in the time domain of an indicator-dilution experiment, the passage to and distribution in the extravascular volume are rapid relative to the velocity of blood in the exchange vessels. We examine here the relations of the extraction of tracer water as tritium oxide (THO) [Ec(THO)] and of the extraction of tracer sodium as 22Na [Ec(22Na)] to extravascular lung water, delta V wev, by adding isotonic fluid to the gas phase of the lungs. The net convective transvascular passage of water is negligible relative to the transendothelial molecular exchange. In 10 experiments in vivo and in 10 experiments in isolated perfused lungs, Ec(THO) increases as delta V wev increases. Ec(22Na) and the permeability-surface area product (PS) for 22Na do not change as delta V wev increases. We conclude that the extraction of THO is determined mainly by the volume accessible to it (flow- or volume-limited distribution) and that the extraction of 22Na is determined mainly by the resistance of the endothelium (barrier-limited distribution). A diffusion limitation in the added alveolar fluid rather than a barrier limitation at the endothelium may moderate Ec(THO).

AbstractIt is frequently asserted that the ongoing process that is commonly referred to as globalization should bring about wide-spread changes in values. Furthermore, it is hypothesized that the unparalleled increases in the flow of capital, goods, services and information coupled with the revolutionary developments in information and communication technologies should result in a convergence of values.This paper is attempt to assess the direction and the magnitude of value change between 1981, when the first WVS/EVS surveys were conducted, and 2001, the last year for which data are available. Data from some 20 countries are analyzed to follow possible changes in values. Furthermore, the paper offers a test of the convergence hypothesis by examining the standard deviations and the coefficients of variation of a wide-ranging list of values.The conclusion is that cultural value change has been rather limited during this period at least for this sample of countries. Among the dimensions studied, marriage, family and gender relations seem to be the area of most significant change. On the other hand, we have found almost no evidence for even a slow convergence of values.

Rationale: The pathology of the digestive tract is frequent in Cameroon. Despite this situation, studies of gastrointestinal pathology are rare. The pathological anatomy service is almost non-existent in the Cameroonian suburbs. Bafoussam in the west of the country is a semi-urban area and one of the rare ones to have a pathological anatomy department. This is why we decided to present the epidemiological data of the pathologies of the digestive tract of this locality. Methods: We carried out a prospective study over three months (October 2019 - January 2020), in the pathological anatomy department of the Bafoussam Regional Hospital in Cameroon with the aim of presenting the structural pathologies of the digestive tract listed in this institution. . Results: the pathology of the digestive tract has an incidence of approximately 400 in this locality, and represents 45.24% of all the pathologies identified in the pathological anatomy department of the Bafoussam Regional Hospital The age of our patients varies between 17 and 98 years old, with an average of 52.8. Women are slightly more represented (sex ratio M: F of 1: 1.3). Samples from the digestive tract represent 45% of all histological samples recorded in this department. The most common location, in decreasing order, is the stomach (84%), followed by the esophagus (5%), the colon and the rectum (4% each). On the other hand, other sites including the duodenum are rather rare. Of 100 samples of the digestive tract examined, 98 were pathological with a preponderance of inflammatory lesions (80.61%) against 19.39% of neoplastic nature. The inflammatory pathology was distributed uniformly in all age groups while the malignant pathologies were not observed until after 50 years. Malignant pathologies were more common in men (sex ratio M: F of 3: 1). Gastritis was the most common diagnosis (76.53%) and 94.66% of these gastritis were associated with Helicobacter pylori. Conclusion: The pathology of the digestive tract is important in our community and dominated by the inflammatory type. The most common site is the stomach, most of the lesions of which are linked to Helicobacter pylori. It would be desirable to actively seek out and eradicate Helicobacter pylori infection to decrease the incidence of digestive pathology. Further studies are recommended to establish the true epidemiological trend of gastrointestinal pathology in our community.

A clear definition of what constitutes “Big Data” is difficult to identify, but we find it most useful to define Big Data as a data collection that is complete. By this criterion, researchers on Caenorhabditis elegans have a long history of collecting Big Data, since the organism was selected with the idea of obtaining a complete biological description and understanding of development. The complete wiring diagram of the nervous system, the complete cell lineage, and the complete genome sequence provide a framework to phrase and test hypotheses. Given this history, it might be surprising that the number of “complete” data sets for this organism is actually rather small—not because of lack of effort, but because most types of biological experiments are not currently amenable to complete large-scale data collection. Many are also not inherently limited, so that it becomes difficult to even define completeness. At present, we only have partial data on mutated genes and their phenotypes, gene expression, and protein–protein interaction—important data for many biological questions. Big Data can point toward unexpected correlations, and these unexpected correlations can lead to novel investigations; however, Big Data cannot establish causation. As a result, there is much excitement about Big Data, but there is also a discussion on just what Big Data contributes to solving a biological problem. Because of its relative simplicity, C. elegans is an ideal test bed to explore this issue and at the same time determine what is necessary to build a multicellular organism from a single cell.

Parental alienation has been widely debated in Brazil by areas of law and psychology, especially in the last ten years. This phenomenon respect to family life of children and adolescents is a topic little explored by the Social Work. Thus, this thesis was to study the object of the analysis of view of social Judiciary workers on parental alienation and the law dealing with the subject. It started from the hypothesis that professionals working in family courts, although dealing with many family disputes, including parental alienation, have not discussed and deepened this. To verify this hypothesis, the research aimed at understanding how to have the first discussions about parental alienation in Brazil and the path to the adoption of Parental Alienation Law, then, to know and analyze the perceptions and actions of social Judiciary assistants in relation to the family, parental alienation and Law No. 12.318/2010 and the contribution of these professionals in identifying the phenomenon through social expertise. The methodological process was based on the historical and social analysis of the legislation on justice and family and the concepts of family and parental alienation, deepening the different positions in the Brazilian reality. Was conducted a quantitative and qualitative survey in the period 2013-2105, being interviewed the social workers who work in family courts and social analyzed reports in which parental alienation manifested itself both from the professional look as through determination court to carry out the technical expertise. The speech content analysis of the interviews and the reports identified as the conceptions of family and parental alienation direct the technical performance of each professional. It was considered that the methodology used, especially the quantitative and qualitative research with the interviewed who manifest spontaneously about subject and allowed the identification of objective and subjective aspects of the discourse. The results show that the subject in question requires a thorough discussion by the professional category and the contribution of the social worker in cases involving parental alienation should be guided by the promotion of guaranteeing the right to family life
A alienação parental tem sido largamente debatida no Brasil pelas áreas do Direito e da Psicologia, sobretudo, nos últimos dez anos. Este fenômeno, que diz respeito à convivência familiar das crianças e adolescentes, é um tema pouco explorado pelo Serviço Social. Assim, esta tese de doutorado teve como objeto de estudo a análise da visão dos assistentes sociais do Judiciário sobre a alienação parental e a lei que trata da temática. Partiu-se da hipótese de que os profissionais atuantes em varas de família, embora lidem com diversos conflitos familiares, entre eles a alienação parental, não têm discutido e aprofundado este assunto. Para verificar esta hipótese, a pesquisa teve como proposta compreender como se deram as primeiras discussões acerca da alienação parental no Brasil e a trajetória até a aprovação da Lei de Alienação Parental para, então, conhecer e analisar a percepção e atuação dos assistentes sociais do Judiciário em relação à família, à alienação parental e à Lei n.º 12.318/2010, bem como a contribuição destes profissionais na identificação do fenômeno por meio da perícia social. O processo metodológico fundamentou-se na análise histórico-social da legislação sobre justiça e família e nos conceitos sobre família e alienação parental, aprofundando as diferentes posições na realidade brasileira. Realizou-se uma pesquisa quantiqualitativa entre o período de 2013-2105, sendo entrevistadas/os assistentes sociais que atuam em varas de família e analisados laudos sociais nos quais a alienação parental se manifestou tanto a partir do olhar da/o profissional como através de determinação judicial para a realização da perícia técnica. A análise do discurso do conteúdo das entrevistas e dos laudos permitiu identificar como as concepções de família e alienação parental direcionam a atuação técnica de cada profissional. Considerou-se que a metodologia utilizada, ou seja, a pesquisa quantiqualitativa, possibilitou que as/os entrevistadas/os se manifestassem de maneira espontânea sobre a temática e permitiu a identificação dos aspectos objetivos e subjetivos presentes nos discursos. Os resultados apontam que o tema requer um debate aprofundado pela categoria profissional e que as contribuições do assistente social nos casos envolvendo alienação parental devem se pautar pela promoção da garantia do direito à convivência familiar

O objetivo desta tese foi estudar experimentalmente o comportamento termodin?mico da Camada Limite Convectiva (CLC) durante o per?odo seco e chuvoso em uma regi?o de clima semi?rido do nordeste brasileiro (NEB), com o uso de radiossondas nos dias 16, 17 e 18 de novembro de 2013 (per?odo seco) e de 03 a 08 de abril de 2014 (per?odo chuvoso) no munic?pio de Apodi-RN e no chuvoso de 09 a 17 de abril de 2011 nos munic?pios de Mossor?-RN e Quixeramobim-CE. Foram lan?ados 15 bal?es (per?odo seco) e 32 em Apodi-RN e 35 em Mossor?-RN e 36 em Quixeramobim-CE (ambos no per?odo chuvoso). Atrav?s das radiossondagens foram coletados dados do perfil de press?o atmosf?rica, temperatura do ar, umidade relativa do ar, velocidade, dire??o do vento e Jatos de Baixos N?veis. Para os dados de superf?cie em Apodi-RN, utilizou-se uma esta??o meteorol?gica port?til de superf?cie e foram calculadas as m?dias, m?ximos e m?nimos a cada 10 minutos durante 24 horas. Foi aplicado o teste T-Student e se constatou que algumas vari?veis meteorol?gicas apresentaram diferen?as estat?sticas significantes ao n?vel de 5%. Para determinar a altura da CLC aplicou-se o m?todo dos perfis utilizando-se a temperatura potencial e foram analisadas tr?s informa??es de cada perfil: a m?dia da camada, o valor na base e no topo. Em Apodi-RN, a altura da CLC foi maior no per?odo seco que no per?odo chuvoso, sendo mais baixa no in?cio da manh? (05:00 HL - Hora Local) e mais alta no final da tarde ?s 17:00 HL. A temperatura potencial foi ligeiramente superior no per?odo seco que no chuvoso atingindo valores m?ximos ?s 17:00 HL. Em Mossor?-RN e Quixeramobim-CE, a altura da CLC no per?odo chuvoso foi mais rasa, mais fria e mais ?mida em ambos os s?tios. O teste T-Student foi aplicado tanto para avaliar a diferen?a estat?stica entre os dados por per?odo quanto por localidade. Os resultados s?o apresentados no Cap?tulo 4.
The Objective of this thesis was to study experimentally the thermodynamic behavior of the Convective Boundary Layer (CBL) during the dry and rainy period in a semi-arid climate region of the Northeast of Brazil (NEB), with the use of radiosondes on days 16, 17 and 18 November 2013 (dry period) and from 03 to 08 April 2014 (rainy period) in the municipality of Apodi-RN and in the rainy period of 09 to 17 April 2011 in the municipalities of Mossor?-RN and Quixeramobim-CE. They were launched 15 balloons (dry period) and 32 in Apodi-RN and 35 in Mossor?-RN and 36 in Quixeramobim-CE (both in the rainy period). Through radiosondings were collected profile data of atmospheric pressure, air temperature, relative humidity, wind speed and direction and Low Level Jets. For surface data in Apodi-RN was used a portable surface weather station to collect data and were calculated the average, maximum and minimum every 10 minutes during 24 hours. It was applied the T-Student test and was found that some weather variables showed statistically significant differences at 5%. To determine the CBL height was applied the profiles method using the potential temperature and it was analyzed three informations from each profile: the average of layer, the value in the base and top. In Apodi-RN, the CBL height was higher in the dry season than in the rainy period, being lowest in the early morning (5:00 HL - Local Time) and highest in the late afternoon 17:00 HL. The potential temperature was slightly higher in the dry season than the in the rainy reaching maximum values at 17:00 HL. In Mossor?-RN and Quixeramobim-CE, the CBL height during the rainy season was shallower, colder and wetter in both sites. The T-Student test was applied both to evaluate the statistical differences between the data by period and by location.The results were shown in the Chapter 4.

Para entender a estrutura de metacomunidades deve se considerar tanto explica??es ligadas ao nicho das esp?cies como mecanismos neutros. Em ambientes estressantes da floresta Atl?ntica a diversidade de plantas ? geralmente baixa e constitu?da de muitas esp?cies raras. V?rias explica??es baseadas no nicho t?m sido propostas para aceitar este padr?o estrutural. Investigamos se um padr?o similar em uma metacomunidade de Restinga no NE do Brasil sugere a predomin?ncia de um dos mecanismos na montagem composicional. Para isto foi feito um levantamento da abund?ncia das esp?cies e de caracter?sticas ambientais abi?ticas de 85 parcelas (25 m?) em uma Restinga no munic?pio do Natal-RN. Tamb?m levantamos suas posi??es espaciais como indicadores da contribui??o neutra. An?lises de parti??o da vari?ncia baseadas em RDA e modelos de efeito misto foram usadas para decompor a explica??o da varia??o composicional. Nossos resultados revelaram a necessidade de considerar tanto explica??es ligadas aos gradientes de estresse do sistema costeiro como da neutralidade. A varia??o da abertura do dossel e de certas propriedades f?sico-qu?micas do solo (ex. ?cido potencial, pH e Na) e da topografia (ex. declividade e altitude) foram os principais promotores abi?ticos de varia??o flor?stica pela parti??o da vari?ncia. Esta an?lise tamb?m selecionou processos espaciais significativos de escala ampla e intermedi?ria. J? os modelos mistos sugeriram a abertura do dossel como a ?nica vari?vel abi?tica e escalas espaciais amplas e finas como indicadoras de processos neutros. Uma interpreta??o que aponte o mecanismo dominante depende desta forma da abordagem anal?tica usada, que pode favorecer a necessidade de requerimentos de nicho espec?ficos ou ocorr?ncias oportunistas sem adapta??es necess?rias ao ambiente costeiro.

mondo universitario ha subito un’ondata di cambiamenti che si possono ricondurre alla ricerca dell’eccellenza, declinata secondo le due dimensioni della valutazione e della rendicontazione. Tre sono quelli più evidenti: il primo, il passaggio da una ricerca curiosity driven a una ricerca funzionale al raggiungimento di risultati valutabili in tempi brevi; dalla ricerca pura a quella applicata, da un approccio problem-making a uno problem-solving, da una conoscenza come processo a una conoscenza come prodotto, da un modello disinteressato a uno utilitaristico (Barnett, 1994); il secondo, riguardante l’offerta formativa: dal momento che si è modificato il modo di concepire l’apprendimento; i curricula tendono a essere definiti in termini di risultati di apprendimento predefiniti (Blackmore, 2016); il terzo, peculiare della struttura amministrativa: dal momento in cui sono divenute essenziali una serie di nuove sovrastrutture (programmazione, valutazione, controlli, comunicazione) rispetto al mandato originario della struttura universitaria si registra un aumento consistente del personale delle strutture amministrative. Questi cambiamenti devono fare i conti con la perdita di prestigio della vita accademica, il cambiamento del ruolo dello studente, che è diventato sempre più importante e l’aumento delle procedure burocratiche che rischiano di ingessare un sistema un tempo caratterizzato da un’elevata autonomia.
Per consentire alle strutture universitarie di affrontare le sfide culturali a partire dagli anni Settanta nelle università nord-americane si sono strutturate iniziative finalizzate allo sviluppo e alla promozione di una migliore offerta formativa. Tali iniziative vengono definite con l’espressione Faculty Development (FD), una policy accademica finalizzata a creare le condizioni per un miglioramento delle competenze di tutti coloro che sono coinvolti nelle attività svolte in un ateneo. Nella realtà italiana emerge la mancanza di una vera politica di formazione al teaching per i ricercatori e i docenti universitari, per non parlare dell’esigenza di superare il pregiudizio, di gentiliana memoria, secondo il quale non è necessario apprendere a insegnare, ma sia sufficiente avere successo nella ricerca, cui si aggiunge nell’ultimo decennio una continua e affannata richiesta al personale accademico di azioni organizzative, valutative e documentali, che assorbono tempo e energie senza il supporto di adeguati apparati gestionali e senza predisporre indagini valutative capaci di misurare l’effettivo esito di tutte queste azioni. L’effetto finale è un evidente declino (Capano et al., 2017) dell’istituzione universitaria. Si può ipotizzare che la cultura del organizzazione propria del Faculty Development possa contribuire nel contesto italiano a fornire azioni a supporto del cambiamento: è quanto mai essenziale dotare gli atenei di risorse funzionali a riqualificare la vita accademica, fornendo al personale accademico gli strumenti necessari per performare una buona scholarship, realizzare un’efficace offerta formativa e attuare adeguate forme di terza missione, capaci di incrementare la vita culturale della comunità. Il presente studio si propone come un’analisi sistematica della letteratura sul tema del Faculty Development, che persegue l’obiettivo di sviluppare una disamina estesa dell’oggetto, in modo che l’esplicitazione della datità raccolta fornisca un’analisi del fenomeno che possa essere di supporto a un’avveduta educational policy nel campo della formazione universitaria.
Nel contesto italiano ad oggi non esiste una cultura di attenzione ai contesti di apprendimento universitario. L’offerta formativa è concepita come offerta di pacchetti curriculari e la predisposizione delle condizioni di apprendimento per il conseguimento del titolo universitario si risolve nella organizzazione di una serie di lezioni, frontali o laboratoriali, senza che tutto questo sia innervato da una specifica intenzionalità didattica. Questa immagine poco confortante non intende affatto trascurare tutti i casi di buone prassi sviluppati nei vari corsi di studio, ma il buono che emerge è demandato all’impegno del singolo, senza che l’istituzione universitaria si interroghi sul come predisporre le condizioni per il potenziamento della qualità dei processi di apprendimento. A fronte di questa situazione la necessità di migliorare la qualità dell’insegnamento non è mai stata così stringente e sfidante come lo è oggi, in un clima di continuo cambiamento della formazione superiore. Nuove tendenze definiscono la formazione superiore, attraversando confini istituzionali e nazionali. Essi influiscono sul modo in cui un insegnamento efficace viene concettualizzato, condotto e supportato, valutato, valorizzato e riconosciuto. È necessario affrontare temi quali l’inadeguata preparazione per il lavoro accademico nei corsi di studio magistrali, l’incapacità dei docenti a trasferire competenze, la crescente complessità degli ambienti accademici, le attese e le responsabilità istituzionali, la necessità di preparare meglio gli studenti con bisogni diversi, e la necessità di stare al passo con i balzi della conoscenza e i cambiamenti nelle professioni. Migliorare la qualità della didattica è inoltre essenziale perché consente di ridurre il numero degli abbandoni. È venuto il momento di transitare da un’offerta formativa di tipo episodico a una prospettiva di esperienze di apprendimento in continuità nel tempo, per accompagnare la formazione dei docenti in un modo strutturalmente organizzato (Webster-Wright, 2009).
Sulla base della rilevazione fenomenica, sono emerse le seguenti domande di ricerca: che cosa è il FD? Cosa consente di fare? Come si mette in pratica? Quali sono le potenzialità? Quali sono i limiti? Il FD ha il compito di incentivare i docenti ad interessarsi ai processi di insegnamento e apprendimento e a procurare un ambiente sicuro e positivo nel quale fare ricerca, sperimentare, valutare e adottare nuovi metodi (Lancaster et al. 2014). È finalizzato a promuovere cambiamento sia a livello individuale sia a livello organizzativo. Occupa un posto centrale il miglioramento delle competenze di teaching (Steinert, 2014). Due importanti obiettivi sono rappresentati dalla promozione delle capacità di leadership e di gestione dei contesti (Steiner et al., 2012). Una volta definite le metodologie del teaching, che possono essere oggetto di apprendimento da parte del personale accademico, è risultato necessario identificare le principali modalità formative che un centro di Faculty Development (FDc) dovrebbe mettere in atto per favorire l’apprendimento delle competenze didattiche. Per comprenderne la funzione reale è stato utile prendere in esame le attività proposte dai più importanti centri del panorama accademico nordamericano, analizzandone la struttura organizzativa, le risorse disponibili ed identificandone le due figure principali: il responsabile dell’organizzazione dei processi formativi e il responsabile della struttura. L’analisi dei casi ha consentito di evidenziare i molteplici servizi che possono essere forniti da un FDc. Questa analisi di realtà è risultata molto utile poiché ha offerto indicazioni pragmatiche ai fini di una politica accademica innovativa anche in ambito italiano. Alla luce degli argomenti sviluppati è stato possibile ipotizzare anche per gli atenei italiani l’istituzione di “Centri per la professionalità accademica”, indicando possibili iniziative da essi realizzabili, che potrebbero trovare spazio nella realtà del nostro paese.

Forgoing life sustaining medical treatment takes on additional complexities depending on the mode of therapy forgone, which often varies in clinical practice. Compassionate extubation of the paralyzed or alert patient requires more in-depth ethical analysis. Some cardiologists are reluctant to deactivate pacemakers, requiring thoughtful comparison of these devices with implantable defibrillators, which do not prompt such debate. Dialysis is a burdensome intervention that may not prolong life and when instituted should be considered a time-limited trial. Enteral and parenteral nutrition create distinct issues in terms of emotional connotation, burden, and benefit.

Education in east Asia varies widely, due to the cultural and political histories of each country. The communist governments of China, North Korea, and Vietnam mandate schooling differently from the limited democracy of Hong Kong and the parliamentary government of Japan. The history of the educational philosophies, systems, and curricula of seventeen East Asian countries are described here, with a timeline highlighting educational developments, and a special day in the life feature, a personal account of what it is like for a student to attend school in that country.

This chapter examines whether the ECOWAS Community Court of Justice (ECCJ or Court), as an international court operating in the West African region with its peculiar sociopolitical and economic context, enjoys any form or degree of actual authority in any of its main functions. The ECCJ’s two contrasting epochs represent a variation in the authority of the Court. Whereas under its 1991 Protocol, the Court enjoyed limited de jure authority with little potential for growing its de facto authority, the 2005 Supplementary Protocol introduced expansions that increased the potential for enhanced de facto authority. Ultimately, the Court’s authority varies significantly both in terms of areas of competence, as among different court-users and in relation to wider communities in its State Parties. Arguably, these variations indicate that different factors influence the responses that the Court attracts from different user-groups.

This chapter examines the impact of crime and accessibility on housing prices. In particular, it assesses the effect of residential burglary on apartment prices in Stockholm, building on previous research that indicated residential burglary—not violence or vandalism—had the greatest effect on apartment prices in the Swedish capital. A review of the literature on hedonic modeling covering more than three decades shows that, despite different modeling strategies, these studies consistently find evidence that crime affects housing prices. Two measures of accessibility are used: a “global” distance decay from Stockholm city center and a “local” measure of accessibility to work expressed as travel costs. Results for all of Stockholm County confirm previous findings once limited to Stockholm municipality only, that residential burglary reduces apartment prices. However, such an effect varies across space and levels of accessibility.

Disorders that primarily impair neuromuscular transmission (NMT) produce weakness that characteristically affects certain muscle groups and varies with activity. Acquired, autoimmune myasthenia gravis (MG) is the most common of these disorders. Much less common are genetic abnormalities of the neuromuscular junction (NMJ), the Lambert–Eaton myasthenic syndrome (LEMS), and toxic effects of various biological and chemical agents. The diagnosis of MG or LEMS is suspected from the history and clinical findings, and is confirmed in most patients by the presence of specific auto-antibodies. The precise diagnosis of most genetic myasthenic syndromes may require sophisticated DNA analysis. Impaired NMT can be confirmed in all of these conditions by repetitive nerve stimulation (RNS) testing and measuring the neuromuscular jitter. Treatment of MG requires selecting among several therapeutic options, taking into consideration the clinical characteristics of the individual patient. Treatment of LEMS and genetic myasthenic syndromes is more limited.

So far, I have stressed the neural basis of the interactive view. In this chapter I discuss issues raised by Adrian. To what extent can we read the neural facts in terms of their implications for our conscious experiences? Neural events in the cerebral cortex lead to conscious events, including (but not limited to) perceptions of sensory events as well as perceptions of our own upcoming actions. The neural strength of a conscious event varies, increasing up the cortical hierarchy. Whereas the standard view may seem natural in terms of our own cognitive and behavioural experiences, and there are classical pathways to support the standard view, there are, in addition to the neural reasons considered in previous chapters, many non-neural reasons for questioning this view and taking an interactive view. I summarize these reasons briefly and then look at some of the many novel questions that are raised about the nervous system by the interactive view.

Dogmatic or closed-minded cognition is directionally biased; a tendency to select, interpret, and elaborate upon information in a manner that reinforces the individual’s prior opinion or expectation. Open-minded cognition is directionally unbiased; a tendency to process information in a manner that is not biased in the direction of the individual’s prior opinion or expectation. It is marked by a tendency to consider a variety of intellectual perspectives, values, attitudes, opinions, or beliefs—even those that contradict the individual’s prior opinion. Open-Minded Cognition is assessed using measures that specifically focus on the degree to which individuals process information in a directionally biased manner. Open-Minded Cognition can function as an individual difference characteristic that predicts a variety of social attitudes and political opinions. These include attitudes toward marginalized social groups (e.g., racial and ethnic minorities), support for democratic values, political ideology, and partisan identification. Open-Minded Cognition also possesses a malleable component that varies across domains and specific situations. For example, Open-Minded Cognition is higher in the political domain than religious domain. In addition, Open-Minded Cognition is prevalent in situations where individuals encounter plausible arguments that are compatible with conventional values, but is less evident when individuals encounter arguments that are extremely implausible or that contradict conventional values. Within a situation, Open-Minded Cognition also varies across social roles involving expertise. Because political novices possess limited political knowledge, social norms dictate that they should listen and learn in an open-minded fashion. In contrast, because political experts possess extensive knowledge, social norms dictate that they are entitled to adopt a more dogmatic cognitive orientation when listening to a political communication.

AbstractThis chapter analyzes family policies across the globe, describing patterns in the development of family allowances, leave schemes, and ECEC services both in developed and developing regions. Using the OECD family database and the ILO global social protection database, it compares the developments in family policy across different regions. The chapter reveals that the way regions and countries in the world have followed the main goals of family policy varies significantly, not only in terms of coverage and quality, but also in terms of design and context of implementation. Despite the efforts made in developing regions are still limited and rarely based on the idea of a universal set of interrelated transfers and services, there is still room for them to learn from the experience of the leaders in family policy.

AbstractThe adult learning sector is particularly diverse. Evidence on how its employees access workplace learning is very limited. Focussing on learning by early career teaching staff, using evidence from eight case studies across four countries (Austria, Italy, Slovakia and the UK) and different sub-fields (from providing basic skills training to corporate sector management courses), the chapter reveals that while staff have high levels of skill, their conditions vary significantly. In general, adult learning teachers’ jobs emphasise self-directed learning and professionalism, and novices’ career pathways are poorly structured. The learning-conduciveness of available work varies significantly; this cannot be attributed only to the type of services provided but also reflects organisational agency. Work organisation and human resource practices affect adult education teachers’ learning experiences, in early career and beyond.

AbstractTurbulent political events of the 1990s marked by the Yugoslav wars, protracted transition from socialism to capitalism, and unstable economic outlook since 2000, have contributed to the preservation of a Serbian welfare system focused on ‘old social risks’, also marked by an exclusionary social protection model that limits access to some benefits to migrants – both foreigners in Serbia and Serbians abroad. Access to most social protection benefits for foreigners residing and working in Serbia depends on the same criteria and requirements as those applied for resident nationals. As the Serbian welfare regime is based on the social insurance model, the entitlement for most social benefits in cash or in kind is based on the employment period and/or payment of compulsory social insurance contributions. However, foreigners remain excluded from accessing non-contributory benefits such as the parental benefits, child allowances or the guaranteed minimum resource scheme. Non-resident nationals have access to social benefits depending on whether the country they reside in has signed social security agreements with Serbia, but range of benefits varies depending on the country.

AbstractMisoprostol has been hailed as a revolution within global maternal health research and policy communities because of its potential to reduce maternal mortality from post-partum haemorrhage and unsafe abortion, allowing relatively safe abortion in legal and illegal settings. However, we know little about how women who want to use misoprostol access it to induce abortion. Based on 15 months of ethnographic fieldwork in Ouagadougou, Burkina Faso, this chapter describes and analyses how women gain access to misoprostol to induce abortion within a setting where induced abortion is legally restrictive and where the legal use of misoprostol is limited to post-abortion care and post-partum haemorrhage. The findings show that women seeking abortions in Ouagadougou are able to access misoprostol through unofficial channels, specifically through health workers and drug vendors. While this unofficial use of misoprostol is relatively safer, and more affordable than other options, access is not equally distributed and the cost women pay for the drug varies significantly. While women with strong social networks and financial resources can access misoprostol easily, other women who do not have money to buy misoprostol may become victims of sexual violence from men from whom they seek abortion services. In Ouagadougou, access to abortion with misoprostol is shaped by health workers and the social and economic conditions of the women who seek it. The study uses the concepts of ‘pharmaceutical diversion’ and ‘domestication’ as adjacent analytical frameworks to emphasize the changing pattern of access to misoprostol. The chapter introduces the importance of looking at safe access to safe abortion.

Uranium was Discovered in 1789 by the German chemist Martin Heinrich Klaproth in pitchblende ore from Joachimsthal, a town now in the Czech Republic. Nearly a century later, the Russian chemist Dmitri Mendeleev placed uranium at the end of his periodic table of the chemical elements. A century ago, Moseley used x-ray spectroscopy to set the atomic number of uranium at 92, making it the heaviest element known at the time. This chapter will deal with the quest to explore that limit and heavy and superheavy elements, and provide an update on where continuation of the periodic table is headed and some of the significant changes in its appearance and interpretation that may be necessary. Our use of the term “heavy elements” differs from that of astrophysicists who refer to elements above helium as heavy elements. The meaning of the term “superheavy” element is still not exactly agreed upon and has changed over the past several decades. “Ultraheavy” is occasionally used. Interestingly, there is no formal definition of “periodic table” by the International Union of Pure and Applied Chemistry (IUPAC) in their glossary of definitions: the “Gold Book.” But there are plenty of definitions in the general literature—including Wikipedia, the collaborative, free, internet encyclopedia which calls the “periodic table” a “tabular arrangement of the chemical elements, organized on the basis of their atomic numbers, electron configurations (electron shell model), and recurring chemical properties. Elements are presented in order of increasing atomic number (the number of protons in the nucleus).” IUPAC’s first definition of a “chemical element” is: “A species of atoms; all atoms with the same number of protons in the atomic nucleus.” Their definition of atom: “the smallest particle still characterizing a chemical element. It consists of a nucleus of positive charge (Z is the proton number and e the elementary charge) carrying almost all its mass (more than 99.9%) and Z electrons determining its size.”

In Italy, from the beginning of the twentieth century, illustrated editions of Quo vadis multiply, starting from that of Treves with drawings by Minardi (1901), down to the popular edition by ‘Gloriosa’ (1921). Related paratexts from the novel and its two cinematic adaptations by Guazzoni (1913) and D’Annunzio–Jacoby (1924) flank these numerous illustrated editions, such as a series of photosculptures by Mastroianni and postcards displaying scenes from the films. Sienkiewicz’s novel itself works on several levels, each one involving a large audience: from a popular one to educated readers. The illustrated editions and postcard series will be dealt with as paratexts, analysed not in terms of their aesthetics or fidelity to the plot but as elements widening the interpretation of Quo vadis in the context of Italian society and culture of that time, and taking into consideration the expectations of an Italian audience. Placed in editions of the novel, the iconographic choices displayed in the illustrations play the role of glosses, or even act as the voices of readers/viewers. Thanks to these paratexts, the novel gains new meanings. Our inquiry has been limited to the period 1900 to 1930, to coincide with the end of the silent-film era and the fading of the echo caused by D’Annunzio and Jacoby’s film. The two films will be the constant iconographic reference point because of their accumulation of all the preceding illustration strategies for Quo vadis and their influence on the subsequent typology of illustrations in a continuous circulation of media.

Abstract The number of primes less than n is a function 1r(n) of the integer n. When a value of n is given, the value 1r(n) is determined, even though no algebraic expression for computing it is known. The area of a triangle is a function of the lengths of its three sides; it varies as the lengths of the sides vary and is determined when these lengths are given definite values. If a plane is subjected to a projective or a topological transformation, then the coordinates of a point after the transformation depend on, i.e. are functions of, the original coordinates of the point. The concept of function enters whenever quantities are connected by a definite physical relationship. The volume of a gas enclosed in a cylinder is a function of the temperature and of the pressure on the piston. The atmospheric pressure as observed in a balloon is a function of the altitude above sea level. The whole domain of periodic phenomena-the motion of the tides, the vibratiuns of a plucked string, the emission of light waves from an incandescent filament-is governed by the simple trigonometric functions sin x and cos x.

There is a strong literature on planning in Britain, but the chapter survey shows that this is less strong in relationship to political and ideological dimensions. Textbooks give little coverage of these areas, rather less than twenty or thirty years ago. Engagement in more specialist writing is also limited, from what is surveyed here, although this varies considerably with the sub-field. There is beginning to emerge fuller consideration in journal articles, responding to the perceived greater ideological component of planning in Britain in the last decade or so. There is a clear gap waiting to be filled, so that planning thinking and planning education can get beyond more limited approaches focused primarily on technical or legal practice and engage with what is really happening to planning at present.

Abstract Chapter 7 concludes by outlining some of the book’s implications for research and policy, including: (1) reframing and setting limits to disciplinary models of borrower partisan politics in EM sovereign debt markets; (2) showing borrower autonomy, so the political economy of demand-side use of markets and official creditors, is central to understanding market flows to EM governments, official credit flows to EM governments, and the composition of EM sovereign debt; (3) suggesting the importance of the demand side to the cyclicality of EM financial flows; (4) highlighting the importance of distinguishing between price and volume in sovereign debt, and ways to make clearer linkages between theory and measurement of flows in the IPE of sovereign debt; (5) advancing questions about politically feasible DMO effects on public debt structure and sustainability; (6) noting a limited literature on domestic bond market depth; (7) identifying how and why the role and effect of ministerial institutions like DMOs varies not only across different aspects of public debt structure, but across different areas of the economy.

Water agencies use energy to pump, treat, and distribute potable water. Wastewater treatment plants use energy to collect, treat, and discharge wastewater. The energy intensity of water—the energy embedded in a unit of water delivered—varies considerably depending on the water source, the location and size of the agency’s service area, and the treatment technology employed. The frequency at which agencies collect energy use data also varies, as does the degree to which those data are available. Available estimates of the energy intensity of water also vary greatly. There is a growing recognition within the water and energy communities that new water supplies will likely be increasingly energy intensive and that water conservation efforts will thus result in energy savings. As a result, there is increasing interest in understanding baseline energy use, projected energy use, and opportunities for reducing energy consumption by water and wastewater agencies. The collection of additional, more consistent and more granular data is essential to gaining this understanding.”

Performance of slider bearings of infinite width but having corrugation of limited extent is investigated numerically, using a commercial Computational Fluid Dynamics (CFD) software package. Lubricant is assumed to be a fluid of power-law type. Over a range of the power-law index, effects of the corrugated section’s location on pressure distribution in the bearing’s fluid film and its load supporting capacity is considered. Load-supporting capacity increases with power-law index n, but saturates when n reaches about 1.7. Ratio of load-supporting capacities between corrugated bearing and smooth-surface bearing varies significantly with respect to n when n < [about 0.8], but stays nearly constant at higher n value. Larger corrugation-wave amplitude enhances the difference in load-supporting capacity between corrugated bearings and the smooth-surface one.

Abstract Muscle disorders and induced muscle atrophy impose critical risks to the well-being of an individual, limiting normal activities of daily living. Several resistance training methods exist that have effectively reversed the progression of muscle atrophy. Weightlifting and hydrotherapy are the two widely practiced schemes for resistance training; however, there is the potential risk of excessive loads exerted on the muscles during weightlifting, and limited accessibility and cost are barriers to hydrotherapy. An alternative is using a resistance band. Some limitations include engaging multiple muscles/joints while only unidirectional resistance is feasible. To address these limitations, a VAriable Resistance Suit (VARS) is designed to provide speed-dependent, bi-directional, and variable resistance at a single joint. As a proof of concept, an elbow module of VARS is developed and validated experimentally. A pilot study shows the changes in flexor and extensor muscle activations in response to eight different levels of resistance modulated by VARS. The clinical implications of VARS remain as future work, but the functionalities implemented in the presented VARS prototype and preliminary results suggest that VARS could be a viable solution and complementary to existing tools and techniques utilized in resistance training.

Random media, such as the turbulent atmosphere, distort the wavefront of a propagating electromagnetic field, thereby degrading the resolution of imaging and surveillance systems to much below their inherent (diffraction or otherwise) limits. It has been proposed,1 and to some extent also experimentally verified,2 that there is always a finite chance to obtain an almost diffraction-limited resolution (over a small field of view) in a series of short-exposure images. In an effort to further quantify this effect, we have carried out a series of imaging experiments in a laboratory simulated ran-dom medium, characterized by relatively slow vari-ations (<5 Hz). A narrow slit was imaged through a volume of water, heated from below, and cooled from above.

Even unusual care in polishing, leads to optics with somewhat damaged faces. The question is to what degree? We will show instrumented indentation is a versatile, quick way to give an answer. Limited power, detail size, or durability are accepted hazards of subsurface damage. Its form varies: ductile materials damage by hardening, and brittle ones have fractured surfaces.

We analyzed experimentally the pre-yield regime of some MRFs. The hearing response is ruled by two successive regimes and limited by an interfacial phenomenon. The initial response is pseudo-elastic and independent from the magnetic field and of the particle volume fraction. The shear-stress limit of this regime is proportional to the square of the magnetic field and to the particle volume fraction. In the next regime, the shear strain is not uniform in the fluid. The increase in average shear stress varies linearly with the increase in average shear strain. The variation coefficient is proportional to the square of the magnetic field and decreases with the particle volume fraction. Finally, a loss of adhesion of the magnetic aggregates with the shearing plate or the magnetic pole occurs. The corresponding shear stress is proportional to the square of the magnetic field and to the particle volume fraction.

Abstract The LQG controllers, designed for the NASA Deep Space Network antennas have small tracking errors and are resistant to wind disturbances. However, during antenna slewing, they induce limit cycling caused by the violation of the antenna rate and acceleration limits. This problem can be avoided by introduction of a command that does not exceed the limits. The command preprocessor presented in this paper generates a command that is equal to the original command if the latter does not exceed the limits, and varies with the maximal (or minimal) allowable rate and acceleration if the limits are met or exceeded. It is comparatively simple since it requires only knowledge of the command at the current and the previous time instants, while other known preprocessors require knowledge of the terminal state and the acquisition time. Thus, the presented preprocessor is more suitable for implementation. In this article analysis of the preprocessor is presented. Also the performances of the preprocessor itself, and of the antenna with the preprocessor is illustrated with typical antenna commands.

Welds made onto in-service pipelines are particularly susceptible to hydrogen cracking. During qualification of welding procedures, limits are often imposed on heat-affected zone hardness (e.g., 350 HV max.) as a way to avoid cracking. The hardness level below which hydrogen cracking does not occur is not a fixed value, but varies as a function of several parameters. The results of previous work resulted in the development of hardness evaluation criteria that can be used to quantify the trade-offs that can be made between HAZ hardness, hydrogen level, and the chemical composition of the materials being welded for welds made onto in-service pipelines. This paper describes a current project that is being sponsored in part by the US Department of Transportation – Pipeline and Hazardous Materials Safety Administration, which is focusing on the further development and validation of these criteria, particularly for modern microalloyed materials and material over a wide range of wall thicknesses. The use of these criteria will reduce the cost and increase the reliability of pipeline modifications and repairs.

Avocado oil currently does not have standards in place to regulate its purity or quality. To set appropriate standards, factors that impact the chemical composition of avocado oil need to be better understood. To help address this, fruits from different regions were harvested throughout the year and processed using lab-scale equipment into oil. The oils’ purity (fatty acid profile, sterols, and triacylglycerols) and quality (free fatty acidity, peroxide value, and specific extinction in UV) were determined in addition to minor components such as tocopherols. It was discovered that growing region and harvest time had a greater impact on fatty acid and sterols profiles than using whole fruit verses only flesh to process the oil. The same standards are set for all avocado oils regardless of the country of origin, this finding indicates it will be important to ensure standards can accommodate oils from different regions. In addition, using poor quality fruit to make oil caused a significant increase in the free fatty acidity compared to using good quality fruit at the time of processing. This work determined a baseline for avocado oil quality parameters by extracting oil from ripe, good quality fruit, which can in turn can inform reasonable limits for avocado oil quality standards.

Households face earnings risk which is non-normal and varies by age and over the income distribution. We show that allowing for these rich features of earnings dynamics, in the context of a structurally estimated life-cycle portfolio choice model, helps to better understand the limited participation of households in the stock market and their low holdings of risky assets. Because households are subject to more background risk than previously considered, the estimated model implies a substantially lower coeffcient of risk aversion and a lower optimal risky share for older workers with low wealth and high earnings.

El sistema financiero panameño es uno de los grandes activos del país. Ha acompañado la fuerte expansión económica que ha permitido a Panamá convertirse en la nación con mayor PIB per cápita de América Latina. Sin embargo, en los últimos años ha venido perdiendo competitividad, presencia en la economía y atractivo para los inversores extranjeros. El objetivo de este trabajo es, justamente, analizar su desempeño reciente, evaluar su nivel de desarrollo y competitividad y ofrecer posibles alternativas para su modernización y para aumentar su capacidad como promotor de una recuperación económica sostenible post COVID-19. Los hallazgos muestran que el sistema financiero tiene carencias importantes para atender a determinados segmentos empresariales y de población y cuenta con un bajo grado de desarrollo de los mercados de valores y de la industria Fintech. Además, la concentración del negocio bancario en pocos segmentos ha promovido el desarrollo de un sistema conservador, con una reducida oferta de productos y una capacidad limitada para adaptarse rápidamente y ofrecer soluciones innovadoras a otros sectores relevantes de la economía. Reconociendo las ventajas y el potencial que el país ofrece, la modernización del sistema financiero debería centrarse, a nuestro juicio, en varios aspectos clave: la reducción del costo regulatorio, el desarrollo del mercado de capitales como un hub regional, el aprovechamiento de la tecnología para lograr eficiencia y reducción de costos y la mayor profundización financiera e inclusión de aquellos grupos socioeconómicos con un limitado acceso a productos.

El primer tomo de la serie Documentos tributarios electrónicos y big data económica para el control tributario y aduanero presenta una visión panorámica de la tributación en América Latina y el Caribe (ALC), en la que resaltan la magnitud y complejidad de la evasión y elusión fiscal. A pesar de varios logros importantes de las administraciones tributarias y aduaneras (ATyA), como la adopción de la factura electrónica (F-e) de segunda generación, que es uno de los avances más destacados por su efecto positivo en la recaudación del impuesto al valor agregado (IVA), su impacto ha sido limitado. También se explican los motivos que limitan el potencial de la F-e de segunda generación y la necesidad de complementarla con la factura electrónica de comercio exterior (F-eCX) y la declaración única de aduanas electrónica (DUA-e), además de otras prácticas de administración tributaria y gestión aduanera. Se destaca la necesidad de implementar el conjunto de los documentos tributarios electrónicos (DT-e), el uso de bases de datos estructuradas y la masificación de la fiscalización electrónica tributaria y aduanera basada en riesgo. Finalmente, se describe el conjunto de los DT-e para lograr un enfoque integrado del sistema impositivo y disponer de la información de todas las operaciones comerciales y financieras de los contribuyentes, de manera de acercar la declaración y pagos de los impuestos a los eventos económicos que los generan.
