Authors: Uysal Irak Doruk 
Published: April 2019

The study aims to investigate the relationship between neuroticism and types of mobbing. It also focuses on the interaction between three types of mobbing with employee attitudes and the role of person-organization fit in this relationship. Data was collected from 329 employees and proposed model was tested through Structural Equation Modelling. Study showed that employees high in neuroticism were more likely report person-related mobbing compared to the work related or physical mobbing. Moreover, as expected work-related mobbing was related to job satisfaction, life satisfaction and turnover intentions where person-organization fit was a mediator. By emphasizing the differences between types of mobbing, new perspectives on how to deal with mobbing at workplace will be explored. New interventions would be developed by focusing the differences between various mobbing experiences in the organizations.

Tradisi Ruwahan Masyarakat Melayu Palembang Dalam Perspektif Fenomenologis
Authors: Niswah Chirun 
Published: April 2019

Tradisi Ruwahan merupakan tradisi yang dilakukan oleh masyarakat Melayu Palembang menjelang Ramadhan tiba. Tradisi Ruwahan ini memiliki makna tersendiri yang terbentuk dari proses kesadaran dan proses konstruksinya. Untuk mengetahui proses kesadaran dan pemaknaan tersebut, artikel ini menggunakan metode penelitian kualitatif dengan analisis perspektif fenomenologis melalui teori kontruksi sosial. Proses kesadaran individu dalam perspektif fenomenologi ini terbagi menjadi tiga pola, yaitu kesadaran yang bersifat subjektif, kesadaran yang bersifat intersubjektif, dan kesadaran yang bersifat objektif. Kesadaran yang bersifat subjektif berasal dari pengalaman dan kesadaran aktor, yang dalam hal ini dilakukan oleh masyarakat Melayu Palembang yang melaksanakan tradisi Ruwahan. Kesadaran intersubjektif didapat oleh aktor memalui proses interaksi antar aktor yang memiliki pemahaman dan kesadaran yang sama. Selanjutnya kesadaran objektif didapatkan oleh aktor melalui pemahaman yang didapatnya dari faktor eksternal, misalnya pemahaman si aktor yang menganggap Ruwahan sebagai tradisi turun temurun dari nenek moyang. Dalam melihat tradisi Ruwahan yang dilakukan oleh masyarakat Melayu Palembang, teori konstruksi sosial memiliki tiga konsep penting sebagai poin analisis, yaitu proses eksternalisasi, proses objektivasi, dan proses internalisasi. Proses eksternalisasi merupakan proses penyesuaian diri seorang aktor dalam dunia sosio-kulturalnya. Proses objektivasi merupakan proses interaksi diri dengan dunia sosio-kultural. Sedangkan proses internalisasi, pelaku melakukan identifikasi diri dengan dunia sosiokultural, yakni mengidentifikasi diri dalam sebuah penggolongan sosial yang berbasis historis dan teologis-ideologi.

Zâd al-Muttaqîn Fî Tauhîd Rabb al-`Âlamîn Syaikh Abdus Shamad al-Palembani
Authors: Al-Kaf Idrus 
Published: April 2019

Zâd-Muttaqîn fi Tauhîd Rabb al-Âlamin is one of the most important works of Syaikh Abdus Shamad al-Palembani, an ulama and a great sufi, who has a huge role in Islamic development in Malay World during the 18th century. This was the only work of his describing completely about Wihdat Al-Wujud. Unfortunately, this work was not widely-recognized by Muslim society. This is because the script was not listed in the Arabic-malay cataloqs. This makes the writer is interested to do some research on this work.Using a single script editing and a standard edition method, this study is expected to result a new edition which will be easily understood by modern readers. Moreover, it will be reviewed the manuscript’s codicology aspects in order to reveal the trace of manuscript history well. This study is also hoped to be able to illustrate about the whole basic framework on his sufistic thingking, mainly if it was related to his thought in the past and previous works.This work was originally rewritten in 1868 by Haji Ma’ruf bin Haji Muhammad Hasyim. This research found that the process of rewriting of this work was carelessly done. The writer found some serious mistakes; the numbering of the pages, miswrite, and some grammatical mistakes. In this work, al-Palembani teaches the basic concept of Tauhid, and then build a doctrine of Wihdat al-wujud on it. - in this case - Wihdat al-Wujud al-Muwahhid. His doctrine was derived from two different concepts; al-Faidh and al-Zhill, which were later combined. The approach used to interpret this teaching was to combine the two different concepts of the scholars from two main streams of sufisms; philosophical and akhlaki mysticism.

Konsep Nation-State dalam Pemikiran Ideologi Politik Melayu Islam pada Abad Ke-19 M (Studi Pemikiran Abdullah bin Abdul Kadir Munsyi (1787-1854)
Authors: Jaya Andi Chandra 
Published: April 2019

The focus of this study is to answer the subject matter of how the concept of the nation-state according to Abdullah Munsyi in the constellation of Malay Islamic political ideology in the 19th century AD and how is the relevance of the concept of the current Indonesian nation state ? The study used the conscience morale theory of Ernest Renan and the social contract theory initiated by J. J. Roussae. This research is included in the library research category and uses historical approaches and political philosophy. The primary data in this study are Abdullah Musnyi's Hikayat Abdullah book published by Yayasan Karyawan, Kuala Lumpur, Malaysia in 2007 and secondary data, in the form of books, journal articles, papers, and others related to research problems. the findings of the research are: 1). In accordance with the theory of conscience morale Ernest Renan and the social contract theory initiated by J. J. Roussae, Abdullah bin Abdul Kadir Munsyi was the originator of nationalism. Through his most important work, Hikayat Abdullah, he put forward the formulation of Malay identity in the formulation of the nation which was understood as a Malay tribe or race who had the right to be involved in determining the Malay political format not as a community under a political system that was authoritarian. 2). His closeness with the British colonial side, thus forming the liberal thinking he obtained from Raffles and his friends. He not only dismantled the manipulation of royal ideology, but at the same time put forward a new view of the existence of a humanist individual. 3). The understanding of nationality has egalitarian values ​​that are very relevant to the current Indonesian context, especially the values ​​of equality (egalitarianism) in the midst of the emergence of conflicts in various conflicts today. Likewise the concept of nation-state is closely related to nationalism and good governance where good governance is based on the absolute existence of transparency, open participation, and accountability in all state activities at every level of state management, so that a clean government is formed.

Decomposition of mortality rates from cardiovascular disease in the adult population: a study for Brazilian micro-regions between 1996 and 2015
Authors: Baptista Emerson Augusto , Queiroz Bernardo Lanza , Rigotti José Irineu Rangel 
Published: April 2019

Cardiovascular disease (CVD) is one of the most serious health issues and the leading cause of death worldwide, causing 30% of deaths in Brazil alone in recent years. However, CVD mortality rates are not uniformly distributed across the country. Brazil is marked by important regional differences resulting from socioeconomic inequality and limited access to health services. Given the spatial distribution of causes and heterogeneity of deaths from cardiovascular disease in Brazil, both at macro and micro levels, the goal of this paper is to investigate how age composition effects and age-specific mortality rates are related to the observed difference in deaths from cardiovascular disease in the adult population (over 30 years of age), by sex, in Brazilian micro-regions from 1996 to 2015. The results suggest there has been a decrease in mortality rates resulting from cardiovascular disease, and that both the effects of age structure and level may have influenced the variation of these deaths in Brazil over the period analyzed. These findings indicate that the Brazilian epidemiological transition is not uniform across and within regions of the country.
Structural Imaging of Daman Pay in the Presence of Overlying Carbonate Build-Up: A Case Study from B9 Area of Mumbai Offshore Basin
Authors: Biswal Debakanta , Nedeer Nasimudeen , Banerjee Subrata , Singh Kumar Hemant 
Published: April 2019

Abstract
The boundary between a thick carbonate layer and its substrata is often a well-defined reflector due to the presence of shaly and clayey layers beneath the carbonates. This reflector and other underlying reflectors result in a velocity pull-up effect because the seismic velocities within the carbonates are higher than that of the surrounding sediments. The geometry of velocity pull-up beneath the carbonate body is related to the geometry of the structure and the thickness of the carbonate body the seismic wave travels through.
In B9 area of Mumbai Offshore basin, the reservoir facies are largely represented by clastics deposited along tidal deltaic lobes. Wells drilled though Daman formation have encountered good quality pay sands within the Daman formation. This pay has produced commercial quantities of hydrocarbons in the vicinity making the area attractive for further exploration and exploitation. The overlying Bombay formation consists mainly of shale with occasional bands of limestone and claystone. The development of thick isolated carbonates bodies within Bombay formation is observed in "C" structure on which "Well-C" is placed. This is seen to significantly constrain the structural configuration in the "C" area. There is a possibility of substantial extension of the "C" structure towards south if the impact of velocity pull up due to carbonate build up can be successfully mitigated. The ultimate challenge is to image the Daman reservoirs, mitigating overburden lateral velocity variations.
In addition to a layered cake depth conversion approach for depth conversion of the time map, a more robust approach, PSDM followed by depth conversion was carried out. This paper highlights the merit of different methods.
Well Preparations for Side-Track Drilling Campaign in an Offshore Environment : An Exercise Resulting in Strategic Economic and Operational Advantages

Abstract
An offshore drilling campaign comprising of four development wells was conducted to augment oil production from a field located off the western coast of India. All four wells were designed to be sidetracked from existing depleted wells of the field. Historically, preparing existing wells in the field for side-track took ~4 days/well of a drilling rig and associated spread cost. This paper presents a case- history of conducting side-track well preparatory activities by a rig-less well intervention spread leading to significant time and cost savings. This method was also the first instance of such an activity being conducted in an offshore environment in India.
Prior to actual side-track drilling from an existing well in a brown field, it is required to abandon the open zones in the existing well and prepare the well for casing window cutting for further drilling to a new sub-surface target. Typical preparation activities include multiple wireline runs to set/retrieve deep set and tubing hanger plugs, well killing, nipple-down X-mas tree, nipple-up BOP, wireline run to cut tubing, retrieval of existing completion and ultimately placement of cement plugs to abandon the parent wellbore. The routine approach in the organization for all previous offshore drilling campaigns was to utilize the offshore drilling rig for afore-mentioned well preparation activities. Substantial rig time was spent incurring the cost of entire rig spread for an average ~4 days/well equivalent to ~40% of total well completion time.
The paper elaborates on rig-less operations set-up consisting of Cementing and Wireline Units utilized to conduct well killing, placement of cement plugs, production tubing cutting and nippling down X-mas tree prior to the mobilization of the drilling rig at the platform. The only operation left for the drilling rig was to pull-out the existing completion string and then drilling operations could commence.
The execution of planned operations was flawless on three wells while one well posed technical limitation due to its high deviation. The rig less well preparation campaign was concluded incident free, ahead of schedule and within budget. This offline exercise prior to rig-move saved ~12 days of drilling campaign time which helped in cutting down on overall drilling campaign cost and also allowed the flexibility of adding more wells to the campaign within fair weather window.
While this was an effort to simplify operations and save costly drilling rig-time in a side-track drilling campaign by conducting some very critical operations offline, these methods can also be adopted for planning well abandonment and decommissioning activities in a mature field.

Abstract
In 2018, an operator in Malaysia completed a sidetrack campaign consisting of injector wells. These wells were planned for maximum productivity via sustainable wellbore zonal isolation. The presence of Carbon Dioxide (CO2) in these wells elevated concern about the zonal isolation of cement across the interval. Moreover, for an injector well, the cement must exhibit resilient properties by design of enhanced mechanical properties to provide long-term isolation based on a cyclic wellbore. An advanced slurry system was designed that enabled the set cement to manifest superior properties in three parameters—corrosion resistance against CO2, flexibility against wellbore stress changes, and expansion to mitigate microannuli.
The design of the slag-based flexible cement system with expanding additive (slag-flex) considered all three parameters in the fit-for-purpose application of a resilient and flexible expansive cement system in a CO2-rich well. The system’s mechanical properties, such as Young’s Modulus, Poisson’s Ratio, and tensile strength, were verified with laboratory-scale testing and validation against stress analysis software to confirm on the resilient and flexible properties. The laboratory testing result demonstrated the improved properties of the system, including high tensile strength and low Young’s modulus. Furthermore, the reduced water content of the system decreases the permeability of set cement and thus increases resistance towards corrosive substance such as CO2.
For certain cases in the past, two separate slurry systems had to be designed—a lead slurry with CO2-resistant properties and a tail slurry with flexible and resilient properties. Often, several issues arose from this practice, including complex logistics due to cement silo blend arrangement and complexity during job execution. Hence, this new system presents a novel idea and methodology that will deliver value to the oilfield industry by integrating CO2 resistance, flexibility and expansion properties in a single slurry system.
The system was successfully pumped in wells in Malaysia; no sustained casing pressure has been recorded to date, and wells have been delivered to their intended zonal isolation requirements without compromising well design and overall integrity. This is an innovative application of this type of cement system in the region, and the long-term zonal isolation and well integrity assurance in these and future wells have the potential to save millions of dollars in remedial work. The cement system is currently recognized as the default technology for CO2-rich injector wells in Malaysia.

Abstract
The block M as a foamy extra-heavy oil field in the Carabobo Area, the eastern Orinoco Belt, has been exploited by foamy oil cold production utilizing horizontal wells. The early producing area has been put into production about 10 years, existing problems of productivity declining and produced gas-oil ratio rising. Therefore, the development optimization for the early producing area should be conducted in order to obtain the more profitable oil recovery.
A typical foamy oil reservoir simulation model using 5 components was created to understand the remaining oil distribution features. Based on above understandings, technical strategies were proposed for infilling well deployment in the early producing area.
Results show that the gravity drainage and gravity differentiation of oil and gas during the cold production of foamy extra-heavy oil from horizontal wells by foam flooding are the main mechanisms for formation of remaining oil. And the influence factors of remaining oil distribution include horizontal well spacing, reservoir thickness, reservoir heterogeneity, interlayer distribution and reservoir rhythm. Thus tor foamy extra-heavy oil CHOP process, the enriched remaining oil area is the place between two adjacent horizontal wells with well spacing of 600m. Therefore, well infilling is an effective measure improving oil recovery factor of cold production, and the well infilling should be implemented as soon as possible to obtain better performance of cold production.
