Evaluating Anti-Graft Agencies Governance Practices in Nigeria
Authors: Ewa Uket E. , Adesola Adebisi. W. , Kankpang Kechi
Published: November 2019

The Nigerian state has witnessed exponential increase in corruption and various anti-graft agencies have been established by government to curb this malaise which has branded the Nigerian state and its citizens all over the world as corrupt. The agencies have over the years been criticized as not being effective and a militia of government in power in the way they prosecute anti-corruption wars. The study evaluated the anti-graft agencies and their governance practices, their effectiveness in addressing the cankerworm in the country by employing the purposive sampling technique where 400 copies of questionnaires were distributed to professional accountants, bankers, journalist and lawyers. The data collected were analyzed using both descriptive and inferential statistics. The study revealed inadequate capacity of the workforce, non-commitment to integrity, ethical values and the rule of law, lack of openness, lack of transparency and accountability. The study recommends amendment of the extant laws establishing the anti-graft agencies for operational efficiency in prosecution, responsiveness to the constitution and adequate and targeted training for officials.

Published: November 2019

This study explores the relationship and the impact of the participation in related activities and autonomy of job performance toward task performance and contextual performance of job performance. The study was conducted on the electrical and electronics (E&E) engineers in the Bayan Lepas Free Trade Zone, Penang. Self-administered questionnaires were distributed through the E&E manufacturing companies’ human resource managers. A total of 1,100 questionnaires were distributed that adapted and adopted the research tools of Govino on participation in related activities, Conway and Monks on autonomy, Williams and Anderson on task performance, and Hochwarter et al. on contextual performance. A total of 181 were returned but 150 questionnaires were useable for this study. A factor analysis was conducted on all variables of the study. Interestingly, participation in work-related variables had been divided into participation in HR-related activities and participation in work-related activities. Results indicated that participation in HR-related activities had no association with task performance but had a low relationship with the contextual performance. Furthermore, the participation in work-related activities had no relationship with both, the task performance and the contextual performance. Finally, the engineers indicated that their autonomy had a low relationship with the task performance and moderate relationship with the contextual performance.

oe betekenisvol is het participatierecht van het kind in de KNMG-meldcode kindermishandeling en huiselijk geweld (2018)?

Ieder kind heeft het recht om te participeren in aangelegenheden die hem of haar betreffen (art. 12 IVRK). In de situatie dat een arts vermoedt of weet dat een kind slachtoffer is van kindermishandeling, is betekenisvolle participatie van het kind bovendien cruciaal voor de arts om te kunnen handelen in het belang van het kind (art. 3 IVRK). De KNMG-meldcode kindermishandeling en huiselijk geweld (2018) regelt de stappen die de arts moet zetten en het afwegingskader dat hij moet volgen voor het doen van een melding van (een vermoeden van) kindermishandeling aan Veilig Thuis. In deze bijdrage wordt nagegaan in hoeverre het participatierecht van het kind gegarandeerd wordt in deze meldcode.

A method for the approximate determination of microparticle amount and mass in biological mixtures using a fractionation process in a centrifugal force field
Authors: Górka Andrzej
Published: November 2019

The paper presents a simplified method of estimating the amount and specific mass of microparticles in complex biological mixtures using the fractionation process in the field of centrifugal forces. In the presented method, using the heaviest blood cells – erythrocytes – as an example, a geometric model of a binary fraction in a borderline equilibrium state formed in the process of blood fractionation was used. In this model, an approximated shape of the erythrocyte and a sample normal distribution of the size and number of microparticles in the examined model fraction filled with erythrocytes were used. Based on publicly available blood data, it has been shown that it is possible to estimate the amount and specific weight of microparticles. The accuracy of such estimation generally depends on the precision of representation of shapes, the degree of filling the fraction with microparticles and on the individual quantitative and dimensional distribution of these particles in the examined fraction. The above conclusions, which determine the accuracy of the method presented, were verified in the paper with the use of rheological blood data, commonly available in literature for various types of measuring containers, which affect the level of filling of a given fraction with microparticles.
Keywords: fractionation of biological mixtures, fractionation of blood components, erythrocyte model, erythrocyte shape, blood components
How Realistic and How Predictive is My Sequence Stratigraphic Interpretation? Stratal Control Volumes, Area, and Trajectories as a Tool to Test Sequence Stratigraphic Interpretations
Authors: Burgess Peter M.
Published: November 2019

It is important to test if a sequence stratigraphic interpretation is realistic. This is particularly true if predictions of stratal geometries are then made on the basis of the interpretation, because clearly the predictive power depends largely on how realistic the interpretation is. Testing is also a basic element of a falsifiable model; a most basic aspect of the scientific method is that in order to be useful, all models and interpretation should be able to be tested and rejected if they fail that test. So how can we test the realism of otherwise of a sequence stratigraphic interpretation? One approach is to determine if rates of change in accommodation and supply controls implied by the interpretation are realistic.
The Stratigraphic Interpretation of Subaerial and Submarine Valleys
Authors: Sylvester Zoltán , Covault Jacob A.
Published: November 2019

Understanding the origin and geometry of largescale erosional surfaces in fluvial and channelized submarine depositional settings is critical for interpreting reservoir architecture and connectivity, as these surfaces strongly influence reservoir heterogeneity. We use simple and fast-running forward stratigraphic models to investigate the geometry and the relative age of complex erosional surfaces that form in both the subaerial and submarine domain.

Because low-sinuosity systems tend to have relatively simple incisional and aggradational geometries, we focus on high-sinuosity systems. Fluvial deposits are commonly preserved on terraces that form during incision, and the basal erosional surface is highly time transgressive. Terraces can form without any external influence as a result of cessation of incision at channel cutoff locations. Similar processes and geometries can be observed in systems containing incising submarine channels. However, extensive deposition of fine-grained sediment in the overbank area of submarine channels tends to result in draping and long-term preservation of terrace geometries.

This is in contrast with fluvial systems, as the incisional terrace morphology can be quickly buried after valley filling initiates. Once incision ceases and aggradation begins, erosional surfaces become less continuous and form an intricate network inside the larger and longitudinally more continuous valley surface. Depending on the rate of aggradation and local rate of lateral migration, the internal erosional surfaces can be similar in vertical extent to a single channel depth, or to multiple channel depths and one channel bend in plan view. Phases of low aggradation cause these scallop-shaped surfaces to connect in the downslope direction and form an extensive erosional surface, without any significant re-incision. As relatively fine-grained deposits (e.g., shale drapes, slides, and debris-flow deposits) are primarily distributed along geomorphic surfaces, differentiating time-transgressive erosional surfaces from geomorphic ones results in a better prediction of reservoir compartmentalization and fluid flow. Understanding the origin and geometry of valleys and their deposits informs the controls on the sequence stratigraphy of basin margins. That is, most erosional surfaces are time transgressive and some of them reflect the autogenic dynamics of valley formation, rather than external forcing.
Sequence Biostratigraphy in Unconventional Resource Plays: Do We Need a Different Paradigm?
Authors: Denne Richard A.
Published: November 2019

Much of industry’s perceptions and applications of biostratigraphy in relation to sequence stratigraphy were developed in expanded, siliciclastic-dominated, continental margin deposits. A nearly universal paradigm is that high concentrations of microfossils, especially planktic forms, are indicative of condensed sections, and more specifically, maximum flooding surfaces (MFS). Thus, planktic abundance curves are often used to identify MFS’s in systems tracts interpretations, for correlations, and to identify potential reservoir seals. Although this is a proven technique on continental margins, it is not necessarily applicable to the study of condensed, organic-rich mud rocks deposited within epeiric seas that are often the target of unconventional resource plays.

There are several assumptions about microfossil abundance curves that are implicit when using them to recognize MFS’s: (1) abundances within samples are reflective of the original microfossil assemblage; (2) high abundances directly correlate to a decrease in clastic input and are not due to other processes; and (3) the microfossils are in situ. The accuracy of a microfossil count is dependent on fossil preservation, recovery, and the selection of representative samples. Diagenetic processes, thermal maturity, redox conditions, and compaction can negatively impact fossil preservation, whereas fossil recovery is often poor in brittle mud rocks and carbonates. Examination of thin-sections has found that microfossil occurrences are often concentrated in discrete laminations or lag deposits, making it difficult to accurately estimate average abundances from thin-sections or core plugs. High microfossil abundances are often related to low sedimentation rates, but they may also be a product of plankton productivity and winnowing by bottom-water currents. Likewise, turbidity currents and other downslope transport processes may produce high concentrations of reworked and/or transported microfossils. It is recommended that sequence biostratigraphy in organic-rich mud rocks should focus on identifying hiatal surfaces, depositional environments, estimating rock accumulation rates, and correlating to updip locations where sequence stratigraphic surfaces are more readily identified.

Este artigo objetiva analisar o discurso documental presente no Projeto Pedagógico do curso de Letras/Português, da modalidade presencial, da Universidade Federal de Santa Catarina (UFSC), campus Florianópolis, no que se refere, especificamente, às práticas de escrita na formação do professor de língua portuguesa. A escrita na universidade relaciona-se ao processo de letramento acadêmico, ou seja, com os usos da escrita - e da leitura - em práticas sociais e culturais no contexto universitário, por meio dos quais ocorre a interpretação, a compreensão e a organização do conhecimento em práticas de escrita dos mais variados gêneros e temáticas. Nessa perspectiva, problematizamos, sob a ótica da Análise de Discurso, a maneira como o discurso documental-institucional propõe e projeta a relação do acadêmico com as práticas de escrita durante o processo de formação. Deste modo, não deixamos de considerar a memória institucional e discursiva que historiciza e permeia a constituição dos dizeres analisados. Finalmente, consideramos que a constituição das práticas de escrita acadêmica é uma necessidade fundamental no processo de formação de professores de língua portuguesa, e, nesse contexto, o discurso documental e institucional colabora para o norteamento das ações no âmbito acadêmico e para a cristalização, manutenção ou atualização de conhecimentos e práticas pedagógicas, inclusive as relacionadas à escrita.

Published: November 2019

Six degrees of freedom (6DoF) Object Detection has great relevance in computer vision due to its use in applications on several areas, such as augmented reality and robotics. Even with the improved results provided by deep learning techniques, object detection of textured and non-textured objects is still a challenge. The objective of this work was to seek improvements in the six degrees of freedom detection of non-textured objects using a Convolutional Neural Network (CNN) approach through the preprocessing of the images that were used for training the network. A State of the art research was carried out on techniques that use CNN to detect objects in six degrees of freedom. We also searched for filters with enhancement factors for detection. Finally, a detection technique based on a CNN was selected and adapted to use single-channel images (grayscale) as input, instead of using three-channel images (RGB) as in the original proposition, aiming to increase its robustness while reducing the complexity of the input images. The technique was also tested with the application of two different preprocessing filters to enhance the objects’ contours on the single-channel images, one being the ”pencil effect”, and the other based on local binary patterns (LBP). With this study, it was possible to evaluate the impact on the CNN detection performance due to the application of both of the filters. The proposed technique used with one channel images and the filters on the images still could not surpass the results of the technique with the three-channel image (RGB), although it indicated paths for improvement. The pencil filter also proved to be more robust than the LBP filter, as expected.
Durability of Portland Concrete Containing Polymeric Fillers and Fly Ash

Published: November 2019

Portland concrete suffers in service brittle failure, extensive crack propagation, and wear rates increasing with time. In spite of all the effort expended, these problems persisted when we had started our project. We used several polymeric fillers and fly ash. Higher compressive moduli than the starting concrete are seen for some compositions, the highest for 5 % of one of the polymers + 5 % fly ash. The same composition has the lowest Taber abrasive wear loss. All composites show lower wear loss values than Portland concrete. After 25 days of acidic degradation in 4.0 molar aq. HCl, the starting Portland concrete suffers stronger degradation that our composites. Polymer swelling mitigates acidic degradation. Repetitive freeze-thaw cycles between 15oF and 85oF show disappearance of the deep voids present before the first cycle in our composites—but not in the Portland cement. While the use of fly ash mitigates contamination of the environment, it is the combination of fly ash with polymers which provides significantly improved properties - tribological, chemical and mechanical ones – of the Portland concrete.
Vorhabenplanung durch Gesetz
Authors: Ziekow Jan
Published: November 2019

In its “Climate Protection Program 2030”, the German Federal Government has brought an instrument back to life which was last used after the German unification to speed up infrastructure development: the approval of traffic infrastructure projects by laws on measures rather than by plan approval decision. As a result of the faster expansion of rail and inland waterways, as much traffic as possible should be shifted from the road to these modes of transport. In preparation for these legislative steps, a study has been commissioned by the Federal Ministry of Transport, which has been reproduced in this volume. On the one hand, it analyses in detail the constitutional requirements under which such measures are permitted. On the other hand, it develops proposals for the distribution of tasks between the actors in a planning procedure concluding with a legislative act.
Associations of Traditional and Peer Cyber-Victimization With Adolescents’ Internet Use: A Latent Profile Analysis
Authors: Gini Gianluca , Marino Claudia , Xie Jia-Yan , Pfetsch Jan , Pozzoli Tiziana
Published: November 2019

Significant overlap exists between traditional victimization and peer cyber-victimization. Yet, they can also be somewhat differentiated. Adopting person-centered approaches, studies showed that multiple classes of peer victimization are distinguishable. In particular, this study analyzed the differences in Internet use, Internet motives and behavior and ethical media use of adolescents who are victimized only (or mainly) online (i.e., “cyber-victims”), their peers who are victimized at school (“traditional victims”), students who are frequently victimized both offline and online (“dual victims”), and students who are not victimized. A sample of 1377 Italian adolescents (49.5% females, age M = 16.13, SD = 1.27) completed self-report questionnaires of traditional and peer cyber-victimization and a variety of Internet-related measures. Latent profile analysis yielded four distinct groups: non-victims (79.6% of the sample), traditional victims (9.2%), cyber-victims (9.1%), and dual victims (2.1%). Among the four groups, dual victims, that is, adolescents who are frequently victimized both at school and online, showed the most problematic use of information and communication technologies (ICT). Dual victims and cyber-victims also reported to engage more frequently than the other groups in a variety of Internet activities (e.g., role-playing games and visiting adult sites). Traditional victims reported more coping and conformity motives for using Internet compared to non-victims and, in the latter case, also to cyber-victims. The current findings may help to better understand the link between traditional victimization and peer cyber-victimization with adolescent’s use of information and communication technologies and may inform prevention and educational programs about positive use of new technologies among adolescents.
How Does Interactivity in a Video Game Render People Susceptible? A Mediating Role of Concrete-level Action Identity in Immersive Media
Authors: Sah Young June , Peng Wei
Published: November 2019

Action identification theory (Vallacher & Wegner, 2012) posits that individuals become open to new meanings of actions when the actions are represented in their minds as concrete details (i.e., understanding actions as concrete identities), rather than abstract meanings (i.e., understanding actions as abstract identities). Based on this, we predicted that video game interactivity renders players susceptible to new ideas of actions performed in a video game, by causing them to conceive the actions as concrete details. In a 2 (medium type: interactive vs. non-interactive) x 2 (meaning of hunting: beneficial vs. harmful) between-subjects experiment (N = 111), participants played or watched a hunting simulation game, then expressed their agreement on a news article reporting either the benefit or harm of hunting. The interactivity group, compared to the non-interactivity group, described their game experience as concrete actions, indicating that they construed actions as concrete identities. Further, these concrete identities led to greater agreement with the news article regardless whether benefit or harm of hunting was reported. These results suggest an indirect effect of interactivity on participants’ susceptibility to a new idea. Implications for using the mental representation approach in media-effect studies were discussed.

Authors: Borovcová Martina , Špačková Adéla
Published: November 2019

The aim of the article is to determine and verify the key assessment indicators for the insurance market by applying the decomposition multi-attribute methods and regression analysis. The assessed specific indicators are qualitative indicators (insurance penetration, claim ratio) and quantitative indicators (gross premium, insurance benefit, number of insurance contracts, number of settled insurance claims, number of employees, number of commercial insurance companies, concentration of the insurance market, and more). The decomposition multi-criteria AHP method (analytic hierarchy process) and ANP method (analytic network process) based on the Saaty pair comparison approach are described, including the computation procedure. The described methods are then applied to determine the preferences of the indicators for the insurance market. Subsequently, a particular regression model is created. Our findings reveal the resulting preferences of individual indicators of the insurance market evaluation and key assessment indicators.

OBJECTIVE To determine the dosing regimen of intravenous ranitidine (IVR) most likely to achieve a gastric pH of ≥4 in critically ill pediatric patients.

METHODS A retrospective cohort study was designed and included patients younger than 19 years with gastric pH samples taken from a nasogastric tube within 24 hours after a dose of IVR in an intensive care unit. Data collection included patient demographics, clinical variables, IVR dosing, and gastric pH samples. Descriptive statistical analysis and multivariable logistic regression analysis with clustering of patients was performed to determine variables associated with odds of obtaining a pH of ≥4.

RESULTS A total of 628 patients (1356 nasogastric samples) met study criteria (median age 1.3 years [IQR, 0.33, 5.7 years]; 53% male). The IVR dose was 0.90 ± 0.30 mg/kg per dose every 8.1 ± 2.9 hours, and 60.9% of patients (n = 383) had a pH ≥4. Patients with a pH value ≥4 had gastric pH samples taken earlier after a dose of IVR (6.7 ± 5.0 vs. 5.9 ± 4.7 hours, p < 0.001) but had no difference in IVR dose per kilogram (0.88 ± 0.31 vs. 0.88 ± 0.26, p = 0.86) or frequency of dosing (7.9 ± 3.2 vs. 7.9 ± 3.2 hours, p = 0.89). A multivariable logistic regression model identified increasing age, decreased kidney function, and decreased time to pH sample after an IVR dose with significantly greater odds of pH ≥4.

CONCLUSIONS The IVR dosing to maintain a gastric pH ≥4 in critically ill pediatric patients should occur more frequently than every 8 hours. Gastric pH evaluation may be necessary to assess IVR efficacy.
Intravenous and Oral Posaconazole Pharmacokinetics in a Five-Year-Old With Mucor: A Case Report and Review of the Literature

Published: November 2019

Posaconazole is a lipophilic triazole antifungal that exhibits variable absorption when administered orally. It possesses a broad spectrum of activity against various fungi, such as Aspergillus and traditionally resistant molds such as Rhizopus and Mucor, which carry a poor prognosis. Unfortunately, the tablet and suspension formulations of posaconazole are Food and Drug Administration approved for treatment of fungal diseases only in patients older than 13 years of age. Furthermore, the approval of the IV formulation is exclusively for adult patients. Nevertheless, the extended spectrum of activity and available dosage forms make it an attractive option for pediatric use. The data that exist to guide dosing of posaconazole in young pediatric patients are limited primarily to case series and case reports. Thus, we recommend therapeutic drug monitoring to ensure both safety and efficacy in pediatric patients. Herein we describe our experience with both oral and IV posaconazole in the salvage therapy of a 5-year-old female with extensive cutaneous Mucor. In contrast to previous reports, which show larger doses may be necessary to obtain therapeutic concentrations in pediatric patients as compared with adults, our patient reached targeted concentrations with weight-based dosing.

L’IMMIGRATION IRRÉGULIÈRE DANS L’ESPACE EURO- MÉDITERRANÉEN ET LA PROTECTION DES DROITS FONDAMENTAUX
Authors: Kerdoun Azzouz
Published: November 2019

La question de l’immigration irrégulière bouscule aujourd’hui les pays des deux rives de la Méditerranée, car le phénomène migratoire engendre de nombreux drames humains à chaque traversée de la mer, inacceptables pour la conscience de l’humanité. La réalité est que cette immigration, vu son caractère « clandestin », ne cesse d’alimenter les débats, tant au niveau européen qu’au niveau maghrébin, voire même au niveau africain. Pour l’Afrique, d’où partent par vagues successives les jeunes migrants, c’est une perte de bras valides pour le développement. La migration irrégulière préoccupe beaucoup les dirigeants politiques, du fait de son ampleur et de son impact sur les pays de transit et d’accueil. Elle serait la cause de problèmes sociaux, politiques et sécuritaires. La crainte est que cette immigration considérée comme « porteuse de risques », constitue une menace et un danger pour la stabilité, la cohésion sociale et l’identité des sociétés d’accueil. Cet article analyse la situation des migrants qui sont en porte à faux avec les législations nationales relatives à l’entrée et au séjour sur le territoire des pays de réception, et relève les violations de leurs droits de l’homme au court des étapes de leur voyage. Ceci demande une protection juridique en considération de la personne humaine, conformément aux principes du droit international qui reconnait et énonce des droits en faveur des migrants et des réfugiés.
Mobilité et modes de vie des travailleurs temporaires qualifiés. Les migrants middling à Montréal
Authors: Désilets Gabrielle
Published: November 2019

Dans cet article, nous distinguons les migrantsmiddlingde l’élite mobile et des travailleurs non qualifiés pour offrir une lecture critique des politiques migratoires misant sur une stratégie éconocentrique d’attraction et de rétention des travailleurs qualifiés, souvent décrits comme des candidats de choix à l’immigration pour leur potentiel d’intégration rapide et sans friction dans les sociétés d’accueil. En exposant les contradictions entre les motivations personnelles et les incitatifs structurels propres au marché du travail mondialisé, nous avançons que la temporalité, couplée à l’éthos de la classe moyenne globale, maintient ces travailleurs dans un entre-deux, entre mobilité et ancrage. Les données présentées sont tirées d’une recherche ethnographique dans les rues, les commerces et les entreprises de l’écosystème créatif du secteur Saint-Viateur Est du quartier Mile End à Montréal. Cette recherche s’inspire de l’urbanisme transnational qui souligne l’importance du lieu et du contexte local et urbain dans l’expérience de mobilité et de migration.
Non-enzymatic primer extension with strand displacement

Published: November 2019

Non-enzymatic RNA self-replication is integral to the emergence of the ‘RNA World’. Despite considerable progress in non-enzymatic template copying, demonstrating a full replication cycle remains challenging due to the difficulty of separating the strands of the product duplex. Here, we report a prebiotically plausible approach to strand displacement synthesis in which short ‘invader’ oligonucleotides unwind an RNA duplex through a toehold/branch migration mechanism, allowing non-enzymatic primer extension on a template that was previously occupied by its complementary strand. Kinetic studies of single-step reactions suggest that following invader binding, branch migration results in a 2:3 partition of the template between open and closed states. Finally, we demonstrate continued primer extension with strand displacement by employing activated 3′-aminonucleotides, a more reactive proxy for ribonucleotides. Our study suggests that complete cycles of non-enzymatic replication of the primordial genetic material may have been facilitated by short RNA oligonucleotides.
The One-Way Street of Integration
Authors: Goetz Edward G.
Published: November 2019

The book examines two contrasting housing policy approaches to achieving racial justice. Integration initiatives and community development efforts have for decades constituted contrasting means of achieving racial equity through housing policy. The book traces the tensions between these two approaches as they have been manifest in different ways since the 1940s. The core argument is that fair housing advocates have adopted a spatial strategy of advocacy that has increasingly brought it into conflict with community development efforts. The book presents a critique of integration efforts of fair housing for targeting settlement patterns while ignoring underlying racism and issues of economic and political power. In the pursuit of regional equity and racial justice, causes that both sides of the integration / community development dispute claim as important, it is the community development movement that has the greatest potential for connecting to social change and social justice efforts.
Satisfaction Level of Insured Farmers about Crop Insurance Schemes in Northern Karnataka

Published: November 2019

Universally agriculture is perceived to be synonymous with risk and uncertainty. Agricultural insurance is one of the risk management strategies to overcome risk to the greater extent. It helps in stabilization of farm production and income of the farming community. Crop insurance will not only helps the farmers to withstand the shock from uncertain situations but also acts as incentive to use the resources efficiently and achieve higher level of productivity. The study was conducted in Karnataka State during the year 2017-18 by using the "Ex-post- facto” research design. Belgavi, Dharwad, Haveri and Vijayapura districts were selected purposively based on more number of insured farmers. Further, two taluks from each district and from each taluk three villages (i.e. total 24 villages) were selected randomly. The sample size for the study was 240. The findings of the study revealed that fifty-one per cent (51.67%) of the insured farmers had low level of satisfaction with respect to crop insurance schemes followed by medium (32.92%) and high (15.41%). The variables such as education, land holding, annual income, extension contact and mass media exposure exhibited positive significant relationship at five per cent level of probability with the satisfaction level of insured farmers. The coefficient of determination (R2) was 0.450 which indicated that 45.00 per cent of the variation in satisfaction level of insured farmers was together explained by all the independent variables. In the present study farmers satisfaction was found to be low. Thus, concerned officers should conduct awareness programmes, inform the farmers on or before conducting the Crop Cutting Experiment, make the loss assessment procedure flexible and hassle free and disperse the claim before starting of the next season.
Local Content Implementation Enhancement through Infrastructure Development in Ghana’s Oil and Gas Industry

Published: November 2019

Since the discovery of oil and gas (O&G) in commercial quantities in 2007, Ghana has made some progress in passing several policies such as Local Content and Participation Framework, ostensibly to stem the effects of resource curse – connotes countries with more natural resources turned to be undeveloped than countries without natural resources. Put it differently, the country’s local content is meant to stimulate industry development by indigenizing the needs of the petroleum industry. However, the above aim is constrained by the country’s infrastructure deficit of about US$ 2.5 billion annually needed to provide the enabling environment for the growth of indigenous companies. The study, therefore, is to propose policy options for enhancing local content implementation through infrastructure development. To that end, the policy implementation in Angola, Brazil and Norway is reviewed, and the research participants are purposively sampled and interviewed. Consequently, the study found that the regulatory institutions and legal framework should be strengthened to attract private investment in infrastructure development. In addition, a special provision should be inserted in future petroleum contracts to support the Infrastructure Fund; through infrastructure-for-oil trade; and encouraging voluntary contribution from oil companies in exchange for reduced taxes into the Infrastructure Fund. The findings contribute to the existing literature in local content development by moving the discussion from training, local employment and goods and services targets to developing host country’s local infrastructure for sustainable development of indigenous and foreign businesses.
SOBRE SUPEREXPLORAÇÃO E CAPITALISMO DEPENDENTE
Authors: Osorio Jaime
Published: November 2019

Este artigo é uma crítica às teses que sustentam que Marx não teria deixado dúvidas de que a força de trabalho de nosso tempo é paga por seu valor, o que exigiria abandonar a categoria de superexploração. Aqui, procuramos mostrar que a violação do valor da força de trabalho é um problema inscrito na teoria marxista e presente em O Capital. Por outro lado, argumentamos sobre a relevância da noção de capitalismo dependente e seu significado para entender as particularidades desse capitalismo, que o separa das trajetórias e objetivos do capitalismo desenvolvido.

ABOUT SUPER- EXPLOITATION AND DEPENDENT CAPITALISM

This article is a critique of the theories that sustain that Marx affirms that the labor force is paid for its value. Here we try to show that a violation of the value of the labor force is a problem inscribed in Marxist theory and present in O Capital. On the other hand, it argues about the importance of the notion of dependent capitalism and its meaning to understand its particularities that separate it from the traits and objectives of capitalism developed.

Key words: Superexplotation; Dependent capitalism; Capitalism patterns

Cet article est une critique des théories qui soutiennent que Marx affirme que la force de travail est payée pour sa valeur. Nous essayons ici de montrer qu’uneviolation de la valeur de la force de travail est unproblèm einscrit dans la théorie marxiste et présent dans O Capital. D’autre part, il argumente sur l’importance de la notion de capitalisme dépendant et sa signification pour comprendre ses particularités qui le séparent des traits et des objectifs du capitalisme développé.

Basophils and mast cells (MCs) play an important role in immune responses against allergens and parasitic infection. To elucidate the mechanisms that determine the commitment between basophils and mast cell (MCs), transcription factors and epigenetic modifications regulating the gene expression of basophil‐specific enzymes, Mcpt8 and Mcpt11, were analyzed using bone marrow‐derived (BM) cells containing basophils and MCs. Knockdown (KD) and overexpression experiments revealed that the transcription factor C/EBPα positively regulated the gene expression of Mcpt8 and Prss34 (encoding Mcpt11). Cebpa, Mcpt8, and Prss34 mRNAs levels were upregulated by histone deacetylases and downregulated by DNA methyltransferases. Gata2 KD significantly reduced the mRNA levels of Mcpt8 and Prss34, while TGF‐β treatment increased those of Mcpt8 and Prss34. These results show that basophil‐specific protease genes were transactivated by C/EBPα, GATA2, and TGF‐β signaling and modified with epigenetic regulation.
Exercise as an abortive treatment for cluster headaches: Insights from a large patient registry
Authors: Kang Mi‐Kyoung , Hong Yooha , Cho Soo‐Jin
Published: December 2024

Objective

This study aimed to evaluate the potential of exercise as an abortive treatment for patients with cluster headache (CH).

Methods

A cross‐sectional survey was conducted among CH patients at a single center in Korea. Demographics and headache characteristics were compared between those who found exercise effective and those who did not. We analyzed the type and intensity of exercise used. Headache improvement was measured as intensity reduction, with ≥50% improvement defined as a reduction in intensity by half or more. Exercise intensity was categorized as moderate (“possible to talk but hard to sing”) or high (“difficult to speak without pausing”). Case reports of patients exercising during CH attacks were also reviewed.

Results

Among 167 registered CH patients, 136 patients provided responses about exercise during CH attacks; 39.7% (54/136) attempted exercise as treatment. Improvement was reported by 42.6% (23/54), with ≥50% improvement in 29.6% (16/54). Patients who found exercise effective had lower Headache Impact Test‐6 scores. Effective exercises included running (39.1%), squats (30.4%), and stair climbing (21.7%), with high‐intensity exercise effective for 52.2% and moderate intensity for 43.5%. Among the 23 patients who benefited from exercise, 18 reported their most effective treatment, which were exercise alone in 50% (9/18), followed by exercise with triptans in 38.9% (7/18), and oxygen with or without triptans in 5.5% (1/18).

Interpretation

About 40% of CH patients attempted exercise for acute CH management, with 30% experiencing over 50% improvement. While evidence is limited, exercise may help alleviate headaches and could be considered an adjunctive treatment for CH attacks.

Objective

To determine the efficacy and safety of combined low‐dose rituximab with conventional therapy for chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) treatment.

Methods

Total 73 patients with CIDP were enrolled for the retrospective cohort study, and divided into conventional first‐line therapy cohort (n = 40) and combined low‐dose rituximab (100 mg per infusion) cohort (n = 33). The outcome measures include scores of I‐RODS, mRS, INCAT, ONLS, TSS, and COMPASS 31 scale at baseline and regular four visits (4, 16, 28, and 52 weeks), as well as proportion of favorable response and outcome, corticosteroids dosage, and deterioration occurrence during follow‐up.

Results

Compared to conventional therapy cohort, combined rituximab cohort presented better improvements and higher proportion of favorable response in scales assessments at each visit, as well as significantly reduced corticosteroids dosage and deterioration occurrence during the follow‐up. Analyses of subgroups showed better improvements in both typical CIDP and CIDP variants in combined rituximab cohort than those in conventional therapy cohort, but had no differences between each other. Early initiating combined rituximab regimen (<10 weeks) showed better improvements than delayed initiation (≥10 weeks) at the first three visits within 28 weeks, while had no difference in favorable prognoses at the last visit of 52 weeks after once reinfusion. No rituximab correlated serious adverse events were reported in our patients.

Interpretation

Our simplified regimen of combined low‐dose rituximab has been firstly demonstrated for the better efficacy and safety than conventional therapy in CIDP treatment.
