Authors: Henkes Hans , Bhogal Pervinder , Aguilar Pérez Marta , Lenz-Habijan Tim , Bannewitz Catrin , Peters Marcus , Sengstock Christina , Ganslandt Oliver , Lylyk Pedro , Monstadt Hermann
Published: June 2019

Background:

Stent-assisted coiling and extra-saccular flow diversion require dual anti-platelet therapy due to the thrombogenic properties of the implants. While both methods are widely accepted, thromboembolic complications and the detrimental effects of dual anti-platelet therapy remain a concern. Anti-thrombogenic surface coatings aim to solve both of these issues. Current developments are discussed within the framework of an actual clinical case.

Case description:

A 33-year-old male patient lost consciousness while doing sport and was administered 500 mg acetylsalicylic acid on site. Computed tomography revealed a massive subarachnoid haemorrhage, and digital subtraction angiography showed an aneurysm of the right middle cerebral artery. Stent-assisted coiling using a neck bridging device with a hydrophilic coating (pCONUS_HPC) was considered as an appropriate approach. Another 500 mg acetylsalicylic acid IV was given. After the single anti-platelet therapy was seen to be effective, a pCONUS_HPC was implanted, and the aneurysm sac subsequently fully occluded using coils. No thrombus formation was encountered. During the following days, 2 × 500 mg acetylsalicylic acid IV daily were required to maintain single anti-platelet therapy, monitored by frequent response testing. Follow-up digital subtraction angiography after 13 days confirmed the occlusion of the aneurysm and the patency of the middle cerebral artery.

Conclusion:

A variety of ways to reduce the thrombogenicity of neurovascular stents is discussed. Hydrophilic surface coatings are a valid concept to improve the haemocompatibility of neurovascular implants while avoiding the use of dual anti-platelet therapy. Phosphorylcholine and phenox hydrophilic polymer coating are currently the most promising candidates. This concept is supported by anecdotal experience. However, formalised registries and randomised trials are currently being established.
Managing acceptable academic outcomes in a context of multiple deprivation: Making do in a South African township school
Authors: Van der Merwe Hettie
Published: June 2019

This article explores the intervention strategy used by the staff and school management team of a South African township school to ensure that final-year learners exposed to an environment of multiple deprivation are adequately prepared for the year-end standardised examination. Analysis of the interview data confirms literature findings on the debilitating effect of multiple deprivation, in the form of absolute poverty, on learners’ chances of learning successfully. Research findings reveal strategies related to an intervention programme to prepare final-year learners for the year-end examination. The intervention programme, consisting of Saturday morning and school holiday morning classes and a study camp event a fortnight before the final examination commences, counteracts inhibiting home and environment conditions, to support learners holistically to achieve acceptable academic outcomes. However, the negative influence on learners’ diligence of extending their final school year over two years and the constraint on knowledge and skills attainment of a pass mark of only 30% for some subjects are adverse factors limiting the chances of social mobility for learners with multiple deprivation.
Are artificial agricultural ponds a suitable alternative nesting habitat for the Little Ringed Plover?
Authors: Guilherme João L , Rocha Afonso , Lousa Hugo , Alves José A
Published: June 2019

Climatic scenarios for the Mediterranean predict an increase in drought and erratic precipitation, which may affect waterbirds breeding in freshwater habitats. Artificial wetlands may provide an alternative for these species when conditions in natural habitats deteriorate. We studied Little Ringed Plovers Charadrius dubius nesting in natural streams and agricultural ponds in southern Portugal. Based on 24 nests and 31 colour-ringed adults, we describe nest-site characteristics, breeding parameters and site fidelity. In streams, nests (n = 17) were in sites with more abundant and coarser gravel, while in ponds there was more vegetation around the nest (n = 7). In both habitats, nests were close and at similar distances to water, but this was unrelated to nest outcome (success of 30.8% across habitats). Nest failure in natural streams was mostly attributable to flooding after heavy rains, while in agricultural ponds cattle trampling was the main cause of failure. Based on their renesting capacity and relatively high breeding site fidelity (25%–36% return rate to same area), we suggest that Little Ringed Plovers may trade-off the overall better conditions of natural streams (i.e. higher availability of nesting substrate, food resources and lower disturbance from cattle) against the stochastic risk of floods. Nevertheless, under current predictions of climate change, agricultural ponds can provide more stable and reliable nesting conditions for this and other species, as unpredictable changes in Mediterranean streams’ flooding regimen may become more frequent. Despite the limitations of our dataset, we provide novel information on the breeding biology of this understudied species and highlight its potential for future research.

Published: June 2019

Stress fractures of the proximal fifth metatarsal are common injuries in elite athletes. Fixation using an intramedullary screw represents the most popular surgery performed for treating these injuries, with excellent results in most cases. However, multiple reports in the literature highlight the possibility of painful hardware, usually related to the presence of the screw head, following intramedullary fixation In this case report, we outline 4 cases of professional athletes who developed lateral-based foot symptoms following complete healing of their surgically treated proximal fifth metatarsal fractures and were found to have significant cuboid edema on magnetic resonance images. We also outline recommendations regarding specific surgical technique considerations aiming to minimize this possible complication.

Lipoprotein Glomerulopathy in a Hispanic Female: A Case Report and Literature Review
Authors: Majeed Nasma K. , McLaughlin Jeanette , Gonzalez Miguel
Published: June 2019

Rationale:

Lipoprotein glomerulopathy (LPG) is a rare renal disorder that features glomerular capillary lipoprotein thrombi, proteinuria, and progressive renal failure. Although most reported cases describe involvement in Asian patients, occurrence in Caucasian and other ethnicities has also been reported.

Presenting concern:

A 28-year-old Hispanic female with a past medical history of hypertension, high cholesterol, gastritis, and a strong family history of renal disease presented with abdominal pain. On admission, her blood pressure was elevated. A computed tomography scan was unremarkable. Her laboratory studies showed proteinuria, high creatinine level, and an abnormal lipid profile.

Diagnosis:

The kidney biopsy showed glomerular capillary lipoprotein thrombi that stained positively for Oil-Red-O, confirming the lipid nature of the material consistent with LPG.

Intervention:

After stabilizing her blood pressure, the patient was started on fenofibrate to treat her high cholesterol and improve her renal function.

Outcome:

Her lipid profile and renal function were initially improved. However, after one year of treatment, her renal function started to decline and the patient was referred to a transplant center for further management.

Novel finding:

To the best of our knowledge, this the first reported incidence of LPG in a Hispanic female.
Impact of Predialysis Psychosocial Conditions on Kidney Transplant Recipient Survival: Evidence Using Propensity Score Matching
Authors: Fu Rui , Coyte Peter C.
Published: June 2019

Background:

An increased number of end-stage renal disease patients suffer psychosocial conditions and may experience delayed access to transplantation due to listing restrictions. However, it remains to be shown whether preexisting psychosocial conditions confer an independent risk factor of poor posttransplant outcomes.

Objective:

We addressed this gap in knowledge by conducting a retrospective cohort study to investigate an independent association between the risk of death after transplant and having a diagnosis of psychosocial conditions 1 year prior to starting dialysis.

Methods:

All cases of adult deceased-donor kidney transplantation performed in Ontario, Canada, between April 1, 2002, and March 31, 2013, were used. Propensity score matching was applied to adjust for potential endogenous bias of using predialysis psychosocial status to predict posttransplant mortality. Survival analysis techniques, including Kaplan-Meier curves and Cox proportional hazards modeling, were also used.

Results:

Our results indicate a 49.4% (hazard ratio [HR] = 1.494 [95% confidence interval (CI) = 1.168-1.913]) increased relative risk of posttransplant death to be associated with predialysis psychosocial conditions, when other factors are held constant. The effect is significant ( P = .001) and is independent of other known predictors of death including advanced age.

Conclusions:

Findings from this study offered strong support for the development of psychosocial evaluation to screen candidates prior to transplant listing and early interventions for transplant candidates with psychosocial concerns.

Revisiting the Paradigm Shift in Trauma Studies: Twenty-Five Years of Veena Das’ ‘Our Work to Cry: Your Work to Listen’
Authors: Gupta Arpita , Bhattacharya Prama , Priya Kumar Ravi
Published: June 2019

While in the 1980s, Diagnostic and Statistical Manual (DSM) III created the diagnostic category of posttraumatic stress disorder (PTSD), social scientists like Veena Das were foregrounding the cultural or contextual processes that were shaping the intense distress of the survivors that the psychiatric model excluded in the study of disaster survivors. As widely held, Das’ work on violence-hit humans, particularly, ‘Our work to cry: Your work to listen’, that is, a chapter in her book, Mirrors of Violence, remains one of the cornerstones in making social scientists realise the precedence to be given to the meanings and subjective experiences of trauma events from the perspective of the survivors. In this article, we attempt to highlight how this work of hers contributed to a paradigm shift in the field of trauma studies by illuminating: (a) the ways in which this shift entails focusing on the experiences of suffering shaped within the cultural and socio-political context, (b) the need to transcend the psychiatric model and (c) how ethnographic fieldwork enables the researcher to focus on the nuances of the everyday experiences of the trauma survivors.
How do you ‘know’ a tribal when you see one? How do you ‘see’ a tribal when you know one?
Authors: Pandya Vishvajit
Published: June 2019

This article considers the formation of anthropological knowledge and ethnographic implications in the course of understanding and framing the category of ‘tribe’ on Andaman Nicobar Islands. Considering events from colonial and post-colonial histories of the Andaman and Nicobar Islands, the article argues that the process of classification and reclassification, motivated by anthropological knowledge and the drive for welfare, creates a discourse that tends to deny cultural and social differentiation or diversity among the various tribal communities that inhabit different parts of the Island archipelago. Statist definitions in other words serve to reduce the conditions and identities of tribal groups into categories of the ‘primitive’, ‘particularly vulnerable’ or presently as just ‘vulnerable’. While such categorisations may have its uses in the allocation of welfare budgets, the sole focus on the category of ‘vulnerability’ obfuscates a more nuanced understanding of the conditions of life and well being among such communities.

The article asks if our ‘categorising impulse’ restrains us from thinking of and problematising questions of ‘agency’ in the self-description and assertion of tribal identities. Why is it that the state or the non-tribal outsider remains indifferent to the deconstruction of the statist category of the ‘vulnerable’? Could the discourse of the ‘changeless de- historicised’ Andaman islander suit the ‘non- tribal’ status quo in the Islands?
Defining the Correlation Between Heroin Overdose and Length of Hospital Admissions
Authors: Reinert Justin , Leis Rachel , Paplaskas Alison , Bakle-Carn Deborah
Published: June 2019

Background:: Heroin has had an overwhelming impact on public welfare and health resources. National surveillance data indicate a 25% increase in drug overdose deaths in Ohio between 2012 and 2017, ranking the state second in terms of drug overdose deaths associated with opioids. Objective:: The primary objective of this evaluation was to determine the length of hospital stay in suspected or confirmed heroin overdose. Methods:: This retrospective analysis evaluated adult patients presenting to the emergency department (ED) at Mercy Health St Vincent Medical Center with confirmed or suspected heroin overdose. Patient data were obtained from the International Classification of Diseases, 10th revision, code reports. The study site is a 462-bed academic medical center with a level 1 trauma designation located in downtown Toledo, OH. Results:: One-hundred and one patients were included in this study: 49 presented to the ED and were subsequently admitted, while 52 were evaluated in the ED and discharged. No statistically significant differences in demographic data were identified. The average length of stay for admitted patients was 4.39 days (range = 0-22 days) with an average of 1.91days in the intensive care unit and 2.48 days on a general medicine floor. Higher average amounts of naloxone administered prior to presentation to the ED were found to predict an admission to the intensive care unit (6.48 mg vs 2.43 mg, P = .0208). The most frequent necessary interventions were central line placement (16/49, 32.7%) and mechanical ventilation (15/49, 30.6%). Seven patients (14.3%) experienced a cardiac arrest. Conclusion:: Heroin overdoses continue to require emergent interventions and consume numerous health care resources. Investment in strategies for prevention of overdose and the subsequent utilization of resources is paramount in controlling the heroin epidemic in Ohio and nationally.
Interesting overlooked findings in melanocytic nevi

Published: June 2019

Since histological analysis is the gold standard for melanoma diagnose, to understand possible findings in nevi is the first step to avoid diagnostic errors. The aim of this paper is to describe several histological features that can be found in nevi and may be misunderstood or overlooked. Histological findings were organized into two groups: 1- adaptive findings (neurotization, sebaceous alteration, adipose metaplasia, amyloid deposition and calcifications, pseudovascular lacunae), 2- findings that can occasionally be associated with malignancy (suspicious for angiolymphatic invasion, perineural infiltration, deep mitosis, muscle infiltration). Each finding by itself does not mean that lesion is malignant. We have selected 13 cases of benign intradermal or compound melanocytic nevi excised for aesthetical purposes from our collection to illustrate possible overlooked findings in melanocytic nevi.
The RNA-binding protein DND1 acts sequentially as a negative regulator of pluripotency and a positive regulator of epigenetic modifiers required for germ cell reprogramming
Authors: Ruthig Victor A. , Friedersdorf Matthew B. , Garness Jason A. , Munger Steve C. , Bunce Corey , Keene Jack D. , Capel Blanche
Published: June 2019

The adult spermatogonial stem cell population arises from pluripotent primordial germ cells (PGCs) that enter the fetal testis around embryonic day (E)10.5. PGCs undergo rapid mitotic proliferation, then enter prolonged cell cycle arrest (G1/G0), during which they transition to pro-spermatogonia. In mice homozygous for the Ter mutation in the RNA-binding protein Dnd1 (Dnd1Ter/Ter), many male germ cells (MGCs) fail to enter G1/G0 and instead form teratomas: tumors containing many embryonic cell types. To investigate the origin of these tumors, we sequenced the MGC transcriptome in Dnd1Ter/Ter mutants at E12.5, E13.5 and E14.5, immediately prior to teratoma formation, and correlated this information with DO-RIP-Seq-identified DND1 direct targets. Consistent with previous results, we found DND1 controls downregulation of many genes associated with pluripotency and active cell cycle, including mTor, Hippo and Bmp/Nodal signaling pathway elements. However, DND1 targets also include genes associated with male differentiation, including a large group of chromatin regulators activated in wild-type but not mutant MGCs during the E13.5 and E14.5 transition. Results suggest multiple DND1 functions and link DND1 to initiation of epigenetic modifications in MGCs.
The Causes and Consequences of Test Score Manipulation: Evidence from the New York Regents Examinations
Authors: Dee Thomas S. , Dobbie Will , Jacob Brian A. , Rockoff Jonah
Published: June 2019

We show that the design and decentralized scoring of New York’s high school exit exams—the Regents Examinations—led to systematic manipulation of test scores just below important proficiency cutoffs. Exploiting a series of reforms that eliminated score manipulation, we find heterogeneous effects of test score manipulation on academic outcomes. While inflating a score increases the probability of a student graduating from high school by about 17 percentage points, the probability of taking advanced coursework declines by roughly 10 percentage points. We argue that these results are consistent with test score manipulation helping less advanced students on the margin of dropping out but hurting more advanced students that are not pushed to gain a solid foundation in the introductory material.

Do 40-Year-Old Facts Still Matter? Long-Run Effects of Federal Oversight under the Voting Rights Act
Authors: Ang Desmond
Published: June 2019

In 2013, the Supreme Court struck down parts of the Voting Rights Act that mandated federal oversight of election laws in discriminatory jurisdictions, prompting a spate of controversial new voting rules. Utilizing difference-in-differences to examine the act’s 1975 revision, I provide the first estimates of the effects of “preclearance” oversight. I find that preclearance increased long-run voter turnout by 4–8 percentage points, due to lasting gains in minority participation. Surprisingly, Democratic support dropped sharply in areas subject to oversight. Using historical survey and newspaper data, I provide evidence that this was the result of political backlash among racially conservative whites. (JEL D72, J15, K16)

Phenotypic detection of Extended Spectrum β-Lactamases (ESBL) among gram negative uropathogens reveals highly susceptibility to imipenem
Authors: Mohammed Isra , Abass Elfadil
Published: June 2019

Objective: We aimed to determine antibiotic susceptibility patterns of ESBL- and non-ESBL bacteria isolated from pregnant women with UTI in antenatal wards in Khartoum State, Sudan.

Methods: This cross-sectional study was conducted during April-July 2016 at different hospitals in Khartoum State. Mid-stream urine samples were obtained from 150 hospitalized pregnant women and cultured on CLED (Cystine Lactose Electrolyte Deficient) agar. Microorganisms were identified using standard microbiological procedures. Isolated Gram-negative bacteria were tested for antibiotic susceptibility and ESBL screening using modified Kirby- Bauer method and Double Disc Synergy Test (DDST) respectively.

Results: Urine culture revealed positive results in 33/150 (22%) and the most prevalent isolates were Gram negative bacteria (18/33, 54.5%). Among gram-negative bacteria, isolates of E. coli were the most prevalent accounting 66.6% (12/18) followed by K. pneumoniae (4/18, 22.2%) and K. oxytoca (2/18, 11.1%). ESBL was detected in 8/18 (44.4%) of the Gram-negative isolates. Of note, imipenem was the most susceptible antibiotic for ESBL-producer and non-ESBL producer Gram negative isolates, accounting 100% susceptibility for both bacterial groups. Overall susceptibility rates were also high for ciprofloxacin (13/18, 72.2%). In other hand, co-trimoxazole and amoxicillin showed high resistance pattern for ESBL-producer and non-ESBL producer isolates; 27.8%, 44.4% and 38.9%, 38.9% susceptibility rates of co-trimoxazole and amoxicillin for ESBL-producer and non-ESBL producer isolates, respectively.

Conclusions: Imipenem remains the most powerful option for ESBL- and non-ESBL bacteria causing UTIs in pregnant women. However, due to tremendous increase of antibiotic-resistant, antibiotic-susceptibility testing is recommended as a routine investigation for admitted pregnant women.

As the goal of the study, the authors see the definition of ways to effectively form a pedagogical culture of heads of internal affairs forces. The research method was the following: the method of expert assessments and the analysis of the results of the pedagogical activity of the heads of the internal affairs forces of Mongolia. The sphere of the general culture of a leader, as a citizen of his country and a person, contains his spiritual and material values. In addition, it is possible to include in this area also methods for the implementation of pedagogical activities that are necessary for society to socialize the individual and ensure the historical process of generational change. That is, the essence of the pedagogical culture of the head of the internal affairs forces is somewhat wider than the sphere of educational activities. Accordingly, during the process of forming the pedagogical culture of the head of the internal affairs forces, a new level of its general culture is being formed, such universal human qualities as spirituality, mercy, a sense of social justice, respect for human dignity, conscience, etc. are being formed. The research results are aimed at improving the efficiency of the existing pedagogical system and activates the process of improving the formation of pedagogical culture among the heads of the internal affairs forces of Mongolia.

Authors: Горач Николай , Gorach Nikolay , Самолаева Евгения , Samolaeva Evgeniya
Published: June 2019

The article deals with the issues related to the study of psychological characteristics of the personality of an individual held criminally liable for cruelty to animals. The data collected by the investigator (inquirer) on the identity of the suspect (accused) are often formal and do not allow an objective assessment of the nature and characteristics of the personality of the individual held liable. The author pays attention to the place of this information in the system of evidence, as well as the impact of data on the identity of the suspect or accused on the adoption of procedural decisions. The article presents the substantiation of the need to study the identity of the person involved in cruelty to animals, on the example of the choice of tactics of investigative actions, the application of rules on exemption from criminal liability in connection with active repentance (Art. 75 of the criminal code), etc. The need for more active use of psychological knowledge in the production of investigative actions and investigation in General. According to the author, the participation of a specialist psychologist in the investigation of criminal cases is evaluated and considered by scientists and practitioners mainly in connection with the production of investigative actions involving minors. At the same time, his participation significantly contributes to the expansion of opportunities for proving circumstances in a criminal case.

Published: June 2019

Various ways are sought today to increase mechanical properties of steels while maintaining their good strength and ductility. Besides effective alloying strategies, one method involves preserving a certain amount of retained austenite in a martensitic matrix. The steel which was chosen as an experimental material for this investigation contained 2.5% manganese, 2.09% silicon and 1.34% chromium, with additions of nickel and molybdenum. An actual closed-die forged part was made of this steel. This forged part was fitted with thermocouples attached to its surface and placed in its interior and then treated using the Q&P process. Q&P process is characterized by rapid cooling from a soaking temperature to a quenching temperature, which is between the Ms and the Mf, and subsequent reheating to and holding at a partitioning temperature where retained austenite becomes stable. The quenchant was hot water. Cooling took place in a furnace. Heat treatment profiles were constructed from the thermocouple data and the process was then replicated in a thermomechanical simulator. The specimens obtained in this manner were examined using metallographic techniques. The effects of cooling rate on mechanical properties and the amount of retained austenite were assessed. The resultant ultimate strength was around 2100 MPa. Elongation and the amount of retained austenite were 15% and 17%, respectively. Microstructures and mechanical properties of the specimens were then compared to the real-world forged part in order to establish whether physical simulation could be employed for laboratory-based optimization of heat treatment of forgings.
Adverse Events Experienced by Patients Hospitalized without Definite Medical Acuity: A Retrospective Cohort Study
Authors: Sekijima Amanda , Sunga Cassandra , Bann Maralyssa
Published: June 2019

Physicians often consider various nonmedical factors in hospital admission decision‐making and may admit socially tenuous patients despite low‐acuity medical needs. Evidence showing whether these patients are subject to the same risks of hospitalization as those considered definitely medically appropriate is limited. Our study sought to inform this risk/benefit discussion by quantifying the number of adverse events (AEs) experienced by both patient populations by using the Institute for Healthcare Improvement Global Trigger Tool methodology. We found no difference in the percentage of admissions with AEs between the two groups (27.3% vs 29.3%; risk ratio 0.93, 95% CI 0.65‐1.34, P = .70) nor in AEs per 1,000‐patient days (76.8 vs 70.4; incidence rate ratio = 1.09, 95% CI 0.77‐1.55, P = .61). Thus, the number of AEs experienced during hospitalization does not appear to be related to the appropriateness of admission based on the level of medical acuity.
The Replenishment Schedule to Minimize Peak Storage Problem: The Gap Between the Continuous and Discrete Versions of the Problem
Authors: Hochbaum Dorit S. , Rao Xu
Published: June 2019

The replenishment storage problem (RSP) is to minimize the storage capacity requirement for a multiitem inventory system, where each item has a given reorder size, uniform demand, and cycle length. The discrete RSP, which allows reorders to take place only at integer time units within the cycle, is NP hard for constant joint cycle length (the least common multiple of the length of all individual cycles). We show that discrete RSP is weakly NP hard for constant joint cycle length and strongly NP hard for nonconstant joint cycle length. For constant joint cycle-length discrete RSP, we present a pseudopolynomial time algorithm that solves the problem optimally and the first known fully polynomial time approximation scheme for the single-cycle RSP. The scheme is utilizing a newly introduced integer programming formulation of the problem. For the strongly NP-hard RSP with nonconstant joint cycle length, we devise a polynomial time approximation scheme, which runs in linear time for fixed $\epsilon$. This paper further explores the relationship of discrete RSP with the continuous RSP, where reorders can take place at any time within a cycle.
A Branch-and-Price-and-Cut Algorithm for Resource-Constrained Pickup and Delivery Problems
Authors: Schrotenboer Albert H. , Ursavas Evrim , Vis Iris F. A.
Published: June 2019

We study a multicommodity, multiperiod, resource-constrained pickup-and-delivery problem inspired by the short-term planning of maintenance services at offshore wind farms. To begin a maintenance service, different types of relatively scarce servicemen need to be delivered (transported) to the service locations. We develop resource-exceeding route (RER) inequalities, which are inspired by knapsack cover inequalities, to model the scarcity of servicemen. In addition to a traditional separation approach, we present a column-dependent constraints approach so as to include the RER inequalities in the mathematical formulation. An alternative pricing strategy is developed to correctly include the column-dependent constraints. The resulting approach is broadly applicable to any routing problem that involves a set of scarce resources. We present a branch-and-price-and-cut algorithm to compare both approaches that include RER inequalities. The branch-and-price-and-cut algorithm relies on efficiently solving a new variant of the elementary resource-constrained shortest-path problem, using a tailored pulse algorithm developed specifically to solve it. Computational experiments show that the RER inequalities significantly tighten the root node relaxations. The column-dependent constraints approach then searches the branch-and-bound tree more effectively and appears to be competitive with the traditional separation procedure. Both approaches are able to solve instances of up to 92 nodes over 21 periods to optimality.

Currently in line with the development of information technology in financial services, the Fintech P2P lending ecosystem and payment gateways are growing rapidly and become one of the cash less payment options, an alternative option for new types of financing due to multi-advantages; fast, collateral-free and technology-based process which is a culture of supporting MSME generation to 3.0. The Fintech P2P Lending and Payment gateway business that is oriented towards IT Base financial reporting still requires a risk management and governance system to reduce and minimize the risk of fraud, bankruptcy, default and other risks. The purpose of this research is to analyze and study innovative solutions to the Fintech business model platform related to protection system management by establishing a central and strategic role between the regulator and Fintech providers. This research uses descriptive research design by using GAP Analysis to research and develop and collaborate on innovation, especially in Fintech business operating systems.

CRISE ORGÃNICA, HEGEMONIA E REVOLUÇÃO PASSIVA GRAMSCIANA
Authors: Militão Maria Socorro Ramos
Published: June 2019

Visando compreender os fatores que originaram o Fascismo na Itália e as derrotas do movimento operário na Europa, o filósofo italiano Antonio Gramsci promoveu uma análise microscópica desses fenômenos e das dimensões que eles atingiram no período da Primeira Guerra e no posterior, assim pôs-se a investigar os fatores que se coligaram e caracterizaram a crise, desencadeada por eles. Essas seriam algumas das questões que receberiam a atenção doautor sardo em sua obra Cadernos do Cárcere, na qual construiria preciosas anotações acerca da crise capitalista que, para ele, não seria apenas uma crise esporádica própria ao sistema, mas uma crise orgânica por ser acompanhada de perda de poder hegemônico. Naquela obra, mostra que a assim chamada crise de hegemonia também desencadeia crises econômicas, políticas, de comando, de autoridade, etc. Por isso, ela deve ser interpretada como um movimento orgânico que se desenvolve em um processo histórico complexo, com sua multiplicidade de componentes e inter-relações em nível global, e não apenas como fenômeno imediato e conjuntural, daí ser provocada por um somatório de questões que se acumularam molecularmente. O autor dos Cadernos aponta como fracasso da política da classe dirigente a imposição do consenso dasgrandes massas pela força; a organização política de grandes massas anteriormente passivas e que passam a se movimentar, embora sem uma vontade política precisa; ou ainda porque as forças antagônicas se mostraram incapazes de organizar em seu favor esta desordem. Diante desse quadro é que se apresenta o objetivo deste artigo: explicitar o processo de desenvolvimento da crise orgânica e a inerente perda de hegemonia decorrente dela, e, com efeito, demonstrar a possibilidade de construção da hegemonia dos e para os subalternos. A investigação em âmbito filosófico-político terá como base teórica o legado gramsciano e, como método de orientação da pesquisa, a filosofia da práxis.
O ENIGMA ONTOLÓGICO DA MERCADORIA COMO PONTO DE PARTIDA D’O CAPITAL DE MARX
Authors: Pereira Leonardo Da Hora
Published: June 2019

Apesar de ser tido normalmente como um livro de economia, de teoria social ouaté mesmo de história, O Capital de Marx possui elementos de grande interesse filosófico. Se adotarmos esse último ponto de vista, torna-se inevitável uma abordagem do primeiro capítulo desta obra, na medida em que ele introduz uma tese curiosa, algo como um enigma ontológico: como algo pode existir de dois modos diferentes, concomitantes e relacionados entre si? Pois esse é o caso da mercadoria, analisada por Marx neste primeiro capítulo. Neste artigo, iremospropor uma leitura deste capítulo com vistas a esclarecer este modo dúplice de existência da mercadoria. Esta tentativa de esclarecimento é a nosso ver relevante, tendo em vista que tal “qüiproquó ontológico” já suscitou inúmeras controvérsias e tal enigma é extremamente importante para a compreensão do resto da obra e da própria dinâmica capitalista, tal como pensada por Marx; não à toa, a explicação do modo de ser da forma-mercadoria se encontra logo no começo do Capital.
ENTRE O DISCURSO E A ONTOLOGIA DO SER SOCIAL: POSSIBILIDADES DE UM DEBATE
Authors: Sombra Laurenio Leite
Published: June 2019

O objetivo deste artigo é fazer um contraponto entre a teoria do discurso de Ernesto Laclau e Chantal Mouffe e a ontologia do ser social de Lukács. Tentamos expor que a dualidade estabelecida por Laclau e Mouffe entre contingência e necessidade, categorias fundamentalmente lógicas, não abarca a ontologia do ser social, que constitui uma objetividade que “tem a sua própria lógica”, nem da necessidade nem da contingência. Lukács, assim como Marx, parte do trabalho como categoria central da passagem de uma ontologia da natureza paraa ontologia do ser social. Aqui se argumenta que a linguagem tem o mesmo peso ontológico do trabalho. Inserindo-se essa dimensão na ontologia de Lukács, alguns dos elementos da teoria do discurso de Laclau e Mouffe, apesar de suas insuficiências, podem ser repensados.
Malvinas. La construcción histórica de una causa nacional en el ámbito escolar (1870-1945)
Authors: Santos La Rosa Mariano
Published: June 2019

En este trabajo buscamos analizar el surgimiento de la “causa” Malvinas como parte de la lenta construcción de un sentimiento nacionalista, partiendo de la hipótesis que la Historia escolar desempeñó un rol importante en dicha conformación. Para ello abordamos el tratamiento que los textos escolares para las escuelas primarias y secundarias realizaron sobre el tema Malvinas entre 1870 y 1945. Situamos la génesis de dicho sentimiento nacional en el ámbito escolar en el contexto de la configuración del código disciplinar de la Historia escolar (Cuesta Fernández 1997) signado por una “educación patriótica” que comenzó a desarrollarse progresivamente desde fines del siglo XIX. A partir de este programa nacionalista la reivindicación de los derechos argentinos sobre las islas se desarrolló primeramente en manuales de Historia utilizados en las escuelas secundarias (desde la década de 1880) y muy posteriormente en textos escolares elaborados para las escuelas primarias, a partir de la década de 1950. Intentaremos explicar en este trabajo las razones de la ausencia del tratamiento de la “causa” Malvinas en el nivel primario durante toda la primera mitad del siglo XX.

Impact of Brexit on the status of the English language in the European Union
Authors: Kużelewska Elżbieta
Published: June 2019

Wielka Brytania przystąpiła do EWG/UE w 1973 r. Jej członkostwo było jednym z drażliwszych problemów w polityce brytyjskiej w ciągu ostatnich czterdziestu pięciu lat. Wielka Brytania jest najbardziej eurosceptycznym państwem członkowskim UE. Wartością dodaną wniesioną przez Londyn do UE był język angielski, który sukcesywnie wypierał język francuski z funkcji języka roboczego Unii. Język angielski jest nie tylko językiem oficjalnym UE (obok pozostałych 23 języków oficjalnych), ale przede wszystkim ma pozycję dominującą w komunikacji pomiędzy UE a światem zewnętrznym oraz pomiędzy instytucjami europejskimi i podczas nieformalnych spotkań. Celem artykułu jest analiza pozycji języka angielskiego w UE, umacniania się jego statusu oraz udzielenie odpowiedzi na pytanie o to czy zachowany zostanie obecny status języka angielskiego w UE po opuszczeniu jej przez Wielką Brytanię.

The Identification of Possible Applications of the E-Loran System
Authors: Czaplewski Krzysztof , Weintrit Adam
Published: June 2019

Global Navigation Satellite Systems (GNSS) more and more affect many areas of human activity in the world. Every day human activity around the world depends upon satellite systems for positioning, navigation and timing. As these systems are commonly used further efforts must be made to make GNSS more immune to on occurring more and more frequently incidents of jamming and spoofing. It seems that eLoran system is currently the best the technical and scientific solution to allowing for effective protection of the Global Navigation Satellite Systems. Last year the authors presented eLoran system as a potential tool for transmission of the national time signal [Curry et al., 2017]. This time the authors present abilities of additional use of the eLoran as a back-up system for GNSS.
Conversion of A Second- To First-Order Linear Nomoto Model in the Light of Zigzag Manoeuvre Performance
Authors: Artyszuk Jarosław
Published: June 2019

The problem of considerable difference between the first- and second-order linear Nomoto models is undertaken, not well covered in literature so far. If the former approximates the latter (better one, of a sound hydrodynamic interpretation) for some reasons, its parameters can not be easily derived from the other one, except for some specific rare cases. For such an identification purpose, we can use a simulated zigzag response and the classic procedure proposed by Nomoto in 1960. However, the first-order model thus developed yields somehow redefined constants against the original model, which lose their normal hydrodynamic (or kinematic) sense. In other words, it is very sensitive to the manoeuvre type on input, being therein the zigzag test. Therefore, the model is allowed to be only used for simulating motions essentially similar to the input zigzag. In other words, the identification procedure works like a blind curve-fitting and the first-order model (in contrast to second-order one) is inadequate for reflecting arbitrary manoeuvres, even for mild rudder as to be within ‘linear’ assumptions.

This study examines systematically and in detail such an incompatibility of the first order model in that it presents the conversion charts from the standpoint of 10°/10° zigzag test matching. One can receive higher or lower values for the parameters of first-order model, versus the second-order one, depending on the T3/T2 ratio of the latter model.
