Modelos de Simulación para la Evaluación de Proyectos de Inversión
Authors: Delgado Tello Pelayo 
Published: February 2020

El modelo de Simulación es un instrumento de evaluación útil que permite analizar con profundidad la evaluación de proyectos de inversión, mejorando la toma de decisión del inversionista. Contribuye a investigar nuevas ideas de proyectos y ayuda a la identificación de las oportunidades de inversión tendientes a la reformulación de proyectos, adecuándose a las actitudes y requisitos del inversionista.
Una alternativa de decisión es mediante la esperanza matemática que se emplea en el cálculo de probabilidades de que se produzca un evento.
El hecho de que no se realice una buena estimación de los elementos que intervienen en el cálculo de rentabilidad, puede conducir a dejar sin validez el análisis, y, por consiguiente, puede dar lugar a que se aprueben proyectos que no sean rentables y viceversa. Cuando se conoce la probabilidad de ocurrencia de un suceso cada cierto número de años, se suele aplicar un determinado porcentaje durante ese periodo. Por ejemplo, si la probabilidad de que ocurra un evento es de 20 años, se aplicará un porcentaje del 5% cada año.
Accrual Management and the Decision to Sell or Hold Shares Acquired from the Exercise of Employee Stock Options
Authors: Smith Thomas J. , Huston G. Ryan , Morton Richard M. 
Published: February 2020

ABSTRACT
This study extends the employee stock option literature by examining how the timing of sales of shares acquired at exercise varies with accrual management both before and after the exercise date. We find evidence that accrual management prior to exercise is positively associated with the decision to quickly sell shares after exercise, increasing the profitability of a short-term exercise-and-sell strategy. Alternatively, we find that post-exercise accrual management is associated with executives choosing to delay selling shares, consistent with minimizing personal income taxes. Specifically, our results suggest that executives are more likely to sell immediately after satisfying the minimum (12 month) holding period for long-term capital gain treatment when they have more income-increasing accruals during the holding period. These results expand on prior research that focused on earnings management leading up to option exercise.

Authors: Pigeyre Marie , Sjaarda Jennifer , Chong Michael , Hess Sibylle , Bosch Jackie , Yusuf Salim , Gerstein Hertzel , Paré Guillaume 
Published: February 2020

OBJECTIVE
To determine whether ACE inhibitors reduce the risk of type 2 diabetes using a Mendelian randomization (MR) approach.

RESEARCH DESIGN AND METHODS
A two-sample MR analysis included 17 independent genetic variants associated with ACE serum concentration in 4,147 participants from the Outcome Reduction with Initial Glargine INtervention (ORIGIN) (clinical trial reg. no. NCT00069784) trial, and their effects on type 2 diabetes risk were estimated from 18 studies of the DIAbetes Genetics Replication And Meta-analysis (DIAGRAM) consortium. A genetic risk score (GRS) underpinning lower ACE concentration was then tested for association with type 2 diabetes prevalence in 341,872 participants, including 16,320 with type 2 diabetes, from the UK Biobank. MR estimates were compared after standardization for blood pressure change, with the estimate obtained from a randomized controlled trial (RCT) meta-analysis of ACE inhibitors versus placebo (n = 31,200).

RESULTS
Genetically lower ACE concentrations were associated with a lower risk of type 2 diabetes (odds ratio [OR] per SD 0.92 [95% CI 0.89–0.95]; P = 1.79 × 10−7). This result was replicated in the UK Biobank (OR per SD 0.97 [0.96–0.99]; P = 8.73 × 10−4). After standardization, the ACE GRS was associated with a larger decrease in type 2 diabetes risk per 2.4-mmHg lower mean arterial pressure (MAP) compared with that obtained from an RCT meta-analysis (OR per 2.4-mmHg lower MAP 0.19 [0.07–0.51] vs. 0.76 [0.60–0.97], respectively; P = 0.007 for difference).

CONCLUSIONS
These results support the causal protective effect of ACE inhibitors on type 2 diabetes risk and may guide therapeutic decision making in clinical practice.
Decolonising Subalternity through Effective History in Ishmael Reed’s Yellow Back Radio Broke-Down and Sonallah Ibrahim’s Zaat
Authors: Abdelgawad Dr. Naeema 
Published: February 2020

In Section One of Manifesto of the Communist Party, Karl Marx and Friedrich Engels, formulating a comprehensive theory of history, contend: The history of all hitherto existing society is the history of class struggles. Freeman and slave, patrician and plebeian, lord and serf, guild master and journeyman, in a word, oppressor and oppressed, stood in constant opposition to one another, carried on an uninterrupted, now hidden, now open fight. (91) Marx and Engels believe that in any society, history marks a conflict between two struggling opposites; noting that the one in the privileged position oppresses the one who is not. Regretfully, that type of struggle never subsides; it seems to be perpetual as it is, sometimes, ‘open’ and, other times, hidden. The same is applied to colonised and ex-colonised countries. However, theirs is not a 'history of class struggles' but of a Master-Subaltern struggle. In this struggle, resisting subalternity is achieved through legitimating the existence of the Subalterns, a process that is realised by urging the colonisers or the colonisers' surrogates to recognise the subalterns' Being, which necessitates admitting not only the existence of the Subalterns, but also being conscious of them as individuals1. This is brought about by occupying a powerful position that is attained through heightening the Subaltern's sense of identity in the course of history. The result is, the paper argues, an active process of decolonising the Self, especially when an 'effective history' comes into existence to pave the way for the Subaltern to achieve self-realisation; as revealed in the Foucauldian thought and, also, the Hegelian and Heideggerian philosophy. The paper aims at analysing the empowerment process of the Subaltern in both Ishmael Reed's Yellow Back Radio Broke-Down (1969) and Sonallah Ibrahim's Zaat (1992) by comparing and contrasting different types of Subalterns as well as colonisers and colonisers' surrogates. The paper also sets out to explore the Subaltern's means of self-projection to acquire a position of power based upon history so as to examine the discourse of history in both African American and Egyptian postcolonial literature.

Abstract
The aim of this study was to estimate a potential beneficial influence of N-acetylcysteine (NAC) in the treatment of cisplatin-induced motor impairment. We included 32 male Wistar albino rats, divided into 4 equal groups: control (received saline on the 1st and 5th day), cisplatin – CIS (received saline on the 1st and cisplatin 7.5 mg/kg i.p. on the 5th day), NAC (received NAC on the 1st and 5th day, 500 mg/kg i.p.), and CIS+NAC (received NAC on the 1st and 5th day, 500 mg/kg i.p. and cisplatin 7.5 mg/kg i.p. on the 5th day) group. Motor performance was estimated by rotarod, grip wire, open field (OF), elevated plus maze (EPM) and beamwalking (BW) tests on the 10th day. Cisplatin administration resulted in decreased motor performance in all tests, except for BW test, compared to the control group. NAC supplementation on its own had no significant effect on motor performance parameters. However, simultaneous administration of NAC along with cisplatin reversed negative impact of cisplatin in rotarod, OF and EPM tests, with no significant effect on the results obtained in grip wire test. The results of this study confirmed numerous motoric manifestations of cisplatin-induced neurotoxicity in rats. However, the decline in most of the estimated parameters was successfully prevented by antioxidant supplementation with NAC.

Abstract
N-methyl-D-aspartate receptor (NMDAR) belongs to iono-tropic glutamate receptor family. The most prominent roles of the NMDAR are related to the physiological and pathophysiological processes of the central nervous system (CNS). The link between NMDAR and cardiovascular pathology came into focus due to detrimental effects of homocysteine on the cardiovascular system. Regarding the fact that NMDAR affects Ca2+ homeostasis in cells, one of the main mechanisms which mediate adverse effects of glutamate dyshomeostasis and abnormal NMDAR activity is oxidative stress. Both in ischemia and during reperfusion, there are imbalance in Ca2+ and production of reactive species, which remains one of the basic mechanisms underlining the overall cardiomyocyte death due to myocardial infarction. The aim of this study was to assess the effects of blockade of NMDAR in heart using MK-801, in preconditioning and postconditioning fashion and to compare the values of oxidative stress biomarkers. We used Langendorff technique of isolated heart. In the control group, all isolated rat hearts were subjected to global ischemia after stabilization period (perfusion of the whole heart with Krebs-Henseleit solution was stopped) for 20 minutes, followed by 30 minutes of reperfusion. In the preconditioning group, after stabilization period, hearts were perfused with MK-801 for 5 minutes, before global ischemia of 20 minutes which was followed by 30 minutes reperfusion. In the postconditioning group, hearts were perfused with MK-801 during the first 3 minutes of reperfusion. Results of this study showed antioxidative effects of NMDAR inhibition in pre- and postconditioning of the isolated rat heart.
MEMPERTEGAS KEDUDUKAN HUKUM KESATUAN MASYARAKAT HUKUM ADAT DALAM MEMENUHI HAK- HAK KONSTITUSIONAL

Published: February 2020

Keberadaan dan hak-hak masyarakat hukum adat telah diterima dalam kerangka hukum tidak tertulis maupun hokum positif di Indonesia. Pada kenyataannya issue yang berkembang tentang kehadiran dan hak- hak masyrakat hukum adat adalah terbatasnya ruang dan gerak bagi komunitas-komunitas adat dalam mewujudkan demokratisasi pengelolaan wilayah adanya secara berkelanjutan, Konflik tenurial, keterbatasan dan kondisi kekayaan alam yang meliputi tanah dan kekayaan alam yang terkandung di dalamnya tidak asimetris dengan pertambahan penduduk. Sehingga perlu adanya penegasan kembali bahwa adanya korelasi antara Kesatuan Masyarakat Adat dengan Pemerintah terkait pemenuhan hak Konstitusionalnya yang terkandung dalam pasal Pasal 18B ayat (2), Pasal 28I ayat (3) dan Pasal 32 ayat (1) dan ayat (2) UUD NRI 1945 dimana aturan ini merupakan semangat otonomi yang diberikan seluas-luasnya kepada daerah. Ketentuan tersebut yang paling sering dirujuk ketika membicarakan mengenai keberadaan dan hak-hak masyarakat hukum adat. Kehadiran Mahkamah Konstitusi sebagai The Protector of the citizen’s and Constitutional Rights and guardian of constitution juga memberikan secercah harapan bagi para pencari keadilan khususnya yang berkaitan dengan perlindungan terhadap hak masyarakat hukum adat
“Un’idea del Brasile”
Authors: Rusconi Paolo 
Published: February 2020

The biography of Pietro Maria Bardi (1900-1999), journalist, art dealer, and founder of MASP (Museu de Arte de São Paulo), presents itself as an exemplary story of Italian intellectual migration to South America during the second half of the 20th Century. This paper privileges a perspective that, taking into consideration the latest results of historiographical research, aims at explaining his vision of Brazil through the relationships previously formed into Fascist Italy and through the dense overlap initiatives related to the experimentation of modern artistic languages. Bardi’s first journey to South America has been in 1933, when he organised and staged an exhibition of new modern Italian architecture. The aim of the trip was to create a consensus around fascism abroad, although the rhetoric of the approach was soon embraced by modernist experiences, particularly by Le Corbusier. The following travel, in 1946 to Brazil, corresponded, for him, to a second life. Around the MASP project, he established a creative colony of artists and architects who took to Brazil the experiences of modernity matured in Europe. The experiences achieved in the urban environment of tropical expanding metropolis, such as the travels to the coasts and the inland areas of Brazil, discovering the nature, the folklore and the native cultures, were crucial sources of inspiration for intellectuals and artists, like the young Italians Roberto Sambonet and Gastone Novelli, who kept a gaze close to the Avant-Garde expressive syntaxes.

Published: February 2020

The lack of high-resolution subsurface images from poor seismic imaging quality leads to inaccurate AVO/AVAz analysis and fault interpretation, which are critical for reserves estimation and de-risking any imminent drilling decisions. In a developing filed, acquiring and processing a new seismic data often falls outside the time frame of ongoing field development, as it will require great efforts in overcoming logistics challenges along with additional costs. In this case study, in offshore Abu Dhabi, revisiting the vintage data with careful and detailed reprocessing whilst utilizing the latest technologies has proven to be an effective, practical and cost-efficient method in improving the fault resolution and reservoir characterization.
In this case study, it is observed that the deeper events in the vintage data were masked by the strong surface wave energy. The irregular acquisition geometry of the seismic data caused the aliasing of the surface wave. The application of harsh de-noising techniques in the vintage processing further deteriorated the fault definition. Thus, to tackle the aliasing problem, 5D trace densification and regularization was applied to increase the input data and create a de-aliased surface wave model. This allowed for subsequent subtraction of the strong surface wave, without damaging the body wave. Further cascaded surface wave attenuation algorithm improved the image quality. Modern fault preserving residual noise attenuation was applied along with 5D Fourier reconstruction mitigated the residual noise content.
It has been proven in the case study that multi-dimensional data densification and 5D reconstruction of the signal enhanced the fault delineation. By leveraging the modern signal-processing innovations, the final results produced a better overall reflection image focused on the angle/azimuth stacks suitable for fault interpretation, AVO and AVAz analysis. In conclusion, poorly vintage seismic data has been shown to possess a high value despite its irregular geometry and low resolution.

Published: February 2020

The poroelastic response of organic-rich formations like shales to stress and pressure changes is yet to be fully understood. The characterization of the poroelastic response of a rock is imperative to understanding the coupled deformation of the rock matrix and pore fluids. In this paper, a new technique is proposed for the laboratory measurement of the poroelastic coefficient utilizing real-time ultrasonic velocity and the comparison with volumetric strain as a function of stress. The high-resolution oscilloscope enables capturing the rock response more accurately over small stress changes. The compressional P-wave first arrival time is monitored during changes in confining stress and pore pressure and is used to obtain the effective stress coefficient (ESC).
In theory, the effective stress coefficient is calculated based on accurate grain and bulk modulus measurements. It is rather difficult to capture the small changes in volumetric strain as a function of stress in ultralow permeability and porosity rocks. The difficulties are associated in the first order with the limitations in the in-vessel instrumentation, accuracy of radial and axial displacement measurements along with the required resolution to obtain representative measurements. In this paper, the effective stress coefficients measured using the automated P-wave real-time first arrival are compared against the effective stress coefficients measured using volumetric strain over a broader pressure range. Results clearly indicate the P-wave velocity to correlate well with the volumetric strain and can be utilized to estimate the poroelastic coefficient. Moreover, utilizing the compressional velocity enables measuring the ESC over small stress perturbations because of its higher sensitivity and better representativeness. The poroelastic coefficient was measured for numerous samples of distinct rock types from various conventional and unconventional plays and was found to vary between 0.2 and 1.0.
Drilling Optimization Approach in Performance Enhancement and Cost Reduction Using a Friction-Reduction Tool in Challenging Applications
Authors: Alnahash Naif , Alghofaili Mohammed , Al-Khalifah Ahmed , Ali Moumien 
Published: February 2020

The steady growth in global demand for hydrocarbons has led to a related increase in Extended Rreach Drilling (ERD). ERD and deeper wells typically see increased drillstring torque and drag, which can causes issues such as weight stacking (and eventually buckling), low rate of penetration (ROP), poor toolface control and associated sliding difficulties. These challenges negatively affect well delivery time and drilling costs.
Reducing torque and drag and its associated issues can be achieved by using a simple Axial Friction Reduction tool (AFR), eliminating the need to explore high-tech drilling solutions that are not as cost-effective. With engineered placement in the drillstring the friction reduction tool creates gentle axial oscillations on the string, reducing friction and dramatically improving weight transfer to the drill bit. This, in turn, increases drilling efficiency in both sliding and rotating modes. Reducing torque and drag through reducing the well friction allows operators to push the boundaries of ERD and enhances their efficiency using the positive displacement motors (PDM) system at lower cost per foot.
On the 12-¼-, 8½-, and 6⅛-in. sections of a recent wells, the friction reduction tool helped decrease torque and drag. As a direct result, weight transfer to the bit was improved extending drill bit life. Furthermore, less Weight on Bit (WOB) was required to drill the sections, enabling higher ROP compared to the drilled offset sections. Consistent weight transfer also allowed all directional requirements to be accomplished and dogleg severity to be more effectively controlled. Applying less weight decreased the overall stress on the drilling system, reducing tool fatigue and the chance of wellbore issues.
This paper will illustrate the added value of using the AFR tool with a PDM in complex vertical, curve and lateral sections while yielding higher efficiency and more cost effective drilling operations.
