On the generation of self-similar with long-range dependent traffic using piecewise affine chaotic one-dimensional maps (extended and renewed version)
Authors: Millán Ginno
Published: May 2021

A qualitative and quantitative extension of the chaotic models used to generate self-similar traffic with long-range dependence (LRD) is presented by means of the formulation of a model that considers the use of piecewise affine one-dimensional maps. Based on the disaggregation of the temporal series generated, a valid explanation of the behavior of the values of Hurst exponent is proposed and the feasibility of their control from the parameters of the proposed model is shown.

Substance Use Behaviors in the Daily Lives of U.S. College Students Reporting Recent Use: The Varying Roles of Romantic Relationships
Authors: Blumenstock Shari M. , Papp Lauren
Published: May 2021

Rationale: While the detrimental consequences of problematic substance use behaviors in early adulthood are well-documented, the interpersonal predictors of substance use in the naturalistic context of daily life are less known. Methods: Using ecological momentary assessments to capture moments of binge drinking, marijuana use, nicotine use, and prescription misuse in everyday life, this study explored the romantic relationship contexts (status, quality, partner presence) of substance use among young adults (aged 18-21) attending a university in the Midwestern U.S. Between 2017-2019, 296 participants, who had endorsed recent substance use at screening for a larger study on prescription misuse, completed four reports per day for approximately 28 days, resulting in over 23000 reports for this investigation. Results: Relationship status, partner support, and partner presence in the moment were all associated with at least one type of substance use behavior. Generalized multilevel models indicated that partnered participants engaged in less marijuana use, nicotine use, and prescription misuse in daily life compared to single participants. Higher partner support predicted less binge drinking, yet also predicted higher nicotine use and prescription misuse. When with a romantic partner in daily life, partnered participants were more likely to engage in binge drinking and marijuana use, and less likely to misuse prescription drugs. Nicotine use was more likely when with a partner, but only if partner support was high. Conclusions: Findings highlight the intricate links between interpersonal contexts and substance behaviors and indicate supportive relationships are not universally protective against substance use among this population.

The sensitivity of changing the optical and thermal physical parameters of the Parabolic Trough Collector
Authors: Mohamad Khaled
Published: May 2021

This work is mainly focused on studying the sensitivity of changing the optical and thermal physical parameters of the Parabolic Trough Collector receiver unit and their corresponding impact on the thermal and optical performances, such as the thermal distribution of the heat transfer fluid along the length, the thermal distribution of both the absorber pipe and the outer cover of the receiver along the circumference and related efficiencies. In this paper, novel experimental results of a receiver unit operating with an IR reflective mirror material inside the receiver are introduced. Besides, novel aspects of the background theory for the reviver unit related to IR reflectivity in the receiver annulus are discussed and implemented in a simulation code. A comparison between a developed model and simulation results is conducted.
The History of Paleontological Investigation in Western Abu Dhabi Emirate
Authors: Beech Mark , Kraatz Brian , Bibi Faysal
Published: May 2021

The story of the discovery of late Miocene fossils within the Baynunah geological formation in Abu Dhabi’s western Al Dhafra region concerns a host of international paleontologists, many of whom have contributed to this volume, as well as the backing of their related scientific institutions. In particular, the first study of the Baynunah owes a lot to the late Peter Whybrow (1942-2004) and a co-editor of the present volume, the late Andrew Hill (1946-2015). The discovery of the majority of the important fossils described in this publication would have not happened without their personal contributions. From the early 1980s until today, the Abu Dhabi government has always been a supportive partner to this paleontological research and continues to document, research, and protect important fossil sites that are part of the late Miocene Baynunah Formation, as well as curate the important collection of fossil specimens resulting from this work. This present publication provides details of the latest comprehensive overview of the Baynunah fossils and updates the earlier volume, Fossil Vertebrates of Arabia (Whybrow and Hill, 1999). A large number of new fossil specimens were discovered during the newer field seasons of work carried out between 2003 and 2018. This has provided an opportunity to undertake major revisions and updates of some of the Baynunah fauna.
Is similarity-based interference caused by lossy compression or cue-based retrieval? A computational evaluation
Authors: Yadav Himanshu , Smith Garrett , Vasishth Shravan
Published: May 2021

The similarity-based interference paradigm has been widely used to investigate the factors subserving subject-verb agreement processing. A consistent finding is facilitatory interference effects in ungrammatical sentences but inconclusive results in grammatical sentences. Existing models propose that interference is caused either by misrepresentation of the input (representation distortion-based models) or by mis-retrieval of the interfering noun phrase based on cues at the verb (retrieval-based models). These models fail to fully capture the observed interference patterns in the experimental data. We implement two new models under the assumption that a comprehender utilizes a lossy memory representation of the intended message when processing subject-verb agreement dependencies. Our models outperform the existing cue-based retrieval model in capturing the observed patterns in the data for both grammatical and ungrammatical sentences. Lossy compression models under different constraints can be useful in understanding the role of representation distortion in sentence comprehension.
Word embeddings reveal an expanding moral circle
Authors: Leach Stefan , Kitchin Andrew , Sutton Robbie M.
Published: May 2021

The Enlightenment idea of historical moral progress asserts that civil societies become more moral over time. This progress is often depicted as an expanding moral circle, and is thought to be driven by language which fosters greater concern for the welfare of others. Our research supports this notion by examining historical trends in natural language use during the 19th and 20th centuries. We found that the associations between words denoting moral concern and words referring to people, animals, and the environment grew stronger over time. This suggests that moral progress is associated with changes in language that are consistent with an expanding moral circle.

Published: May 2021

Adolescents with a visible difference can experience difficult social situations, (e.g., people staring or making unwanted comments) and are at risk for mental health problems. Unfortunately, interventions for adolescents with a visible difference experiencing appearance-related distress are scarce and lack an evidence-base. This study tests the acceptability and feasibility of YP Face IT, an innovative online psychological intervention using social skills training and cognitive behavioural therapy, to Dutch adolescents. Adolescents aged 12-17 with a visible difference and access to an internet-enabled computer or tablet participated. They completed YP Face IT (eight sessions) and questionnaires were administered pre- and post-intervention. After completing YP Face IT, participants were interviewed to assess the acceptability and feasibility of YP Face IT and study procedures. Overall, 15 adolescents consented to participation, one person dropped out after one session. Most adolescents appreciated the intervention and all would recommend it to other adolescents experiencing appearance-related distress. Everyone reported learning experiences after following the sessions. Some struggled with motivation, but reminders by the website and research team were helpful. The Dutch YP Face IT intervention may be acceptable and the current study design is feasible to use. An RCT should be conducted to assess the effectiveness of the intervention.
精简版性幸福感量表（中文版）[Chinese Version of the Short Sexual Well-Being Scale]
Authors: Gerymski Rafał , Wang Pingping
Published: May 2021

Sexual well-being is often mistakenly operationalized simply as sexual satisfaction. The concept of sexual well-being has been often used as an umbrella term for positive aspects of sexuality, apart from its negative spheres. A new concept of sexual well-being was proposed in line with the World Health Organization (WHO) definition of sexual health. The definition tried to enrich the concept of sexual well-being, but it did not solve the problem of its operationalization. Two separate studies were conducted for the psychometric validation of the Short Sexual Well-Being Scale. Short Sexual Well-Being Scales shows good psychometric properties in its original version. These properties are yet unknown for the its Chinese translation.

COVID-19: An opportunity to strengthen Public Health Policy and Advocacy Efforts in LMIC (Low- Middle-Income Countries)
Authors: Mahayosnand Ponn P , Essa Saman , Sabra ZM
Published: May 2021

Similar to how physicians practice evidence-based medicine to treat individual patients, policymakers should govern the public's health according to evidence-based data. Initiated by the World Health Organization's directive to make COVID-19 research open and freely accessible, (1,2) multidisciplinary studies are still published daily. Collectively, policymakers worldwide have not used available data effectively to make noteworthy reductions in the pandemic that is now over a year old. This brief commentary introduces a policy problem, then shares 3 categories of successful case studies as possible solutions: [1] Low- and Middle-Income Countries (LMIC): Vietnam and Iran, (3,4) [2] public health practitioners: social workers in Africa and pharmacists in Zambia, (5,6) and [3] public health programs: a smoking cessation program and inmate health program. (7,8) Examples from LMIC were selected to demonstrate practical, cost-effective and duplicable methods. A collaborative multidisciplinary approach with community health partners is also proposed.

Difference in predictors and barriers to arts and cultural engagement with age in the United States: A cross-sectional analysis using the Health and Retirement Study
Authors: Fluharty Meg , Paul Elise , Bone Jessica Katherine , Bu Feifei , Sonke Jill , Fancourt Daisy
Published: May 2021

Introduction: Arts and cultural engagement are associated with a range of mental and physical health benefits, including promoting heathy aging and lower incidence of age-related disabilities such as slower cognitive decline and slower progression of frailty. This suggests arts engagement constitutes health-promoting behaviour in older age. However, there are no large-scale studies examining how the predictors of arts engagement vary with age. Methods: Data from the Health and Retirement Study (2014) were used to identify sociodemographic, life satisfaction, social, and arts appreciation predictors of (1) frequency of arts engagement, (2) cultural attendance, (3) difficulty participating in the arts, and (4) being an interested non-attendee of cultural events. Logistic regression models were stratified by age groups [50-59, 60-69, 70] for the frequency of arts participation outcome and [50-69 vs 70] all other outcomes. Results: Findings indicated a number of age-related predictors of frequent arts engagement, including gender, educational attainment, wealth, dissatisfaction with ageing, and instrumental activities of daily living (iADL). For cultural event attendance, lower interest in the arts predicted lack of engagement across age groups, whereas higher educational attainment and more frequent religious service attendance became predictors in older age groups (> 70). Adults in both age groups were less likely to report difficulties engaging in the arts if they had lower neighbourhood safety, whilst poor self-rated health and low arts appreciation also predicted reduced likelihood of this outcome, but only in the younger (50-69) age group. Adults in the older (> 70) age group were more likely to be interested non-attendees of cultural events if they had higher educational attainment and less likely if they lived in neighbourhoods with low levels of safety. Conclusions: Our results suggest that certain factors become stronger predictors of arts and cultural engagement and barriers to engagement as people age. Further, there appear to be socioeconomic inequalities in engagement that may increase in older ages, with arts activities overall more accessible as individuals age compared to cultural engagement due to additional financial barriers and transportation barriers. Ensuring that these activities are accessible to people of all ages will allow older adults to benefit from the range of health outcomes gained from arts and cultural engagement.
Practical Lessons for Government AI Projects
Authors: Ramizo Godofredo Jr
Published: May 2021

Governments around the world are launching projects that embed artificial intelligence (AI) in the delivery of public services. How can government officials navigate the complexities of AI projects and deliver successful outcomes? Using a review of the existing literature and interviews with senior government officials from Hong Kong, Malaysia, and Singapore who have worked on Smart City and similar AI-driven projects, this paper demonstrates the diversity of government AI projects and identifies practical lessons that help safeguard public interest. I make two contributions. First, I show that we can classify government AI projects based on their level of importance to government functions and the level of organisational resources available to them. These two dimensions result in four types of AI projects, each with its own risks and appropriate strategies. Second, I propose five general lessons for government AI projects in any field, and outline specific measures appropriate to each of the aforementioned types of AI projects.
Exploring the velocity end of the force-velocity relationship in acyclic lower limb extensions
Authors: Rivière Jean Romain , Morin Jean-Benoit , Bowen Maximilien , Messonnier Laurent A. , Samozino Pierre
Published: May 2021

Purpose: compare linear and curvilinear models to describe the force-velocity relationship, especially on the velocity end, in lower limb acyclic extensions. Methods: nine athletes performed horizontal lower limb extensions on a leg press ergometer allowing to set from very high to very low (i.e. horizontal assisted extensions) resistive and inertial conditions. Lower limb force and velocity were continuously measured over the push-off in six resistive conditions to determine individual force-velocity relationships. Goodness of fit (GoF) of the linear model on force and velocity data (using the basic first order polynomial function), was compared to that of curvilinear models (using the basic second order polynomial function, Fenn and Marsh’s, and Hill’s equations) based on the Akaike Information Criterion (AIC). Results: When expressed relative to the theoretical maximal force (F0-L) and velocity (v0) obtained from the linear model, force and velocity data ranged from 26.6±6.6 to 96.0±3.6%F0-L and from 8.3±1.9 to 76.6±7.0%v0-L (range of individual values=5-86%v0-L and 16-99%F0-L). Curvilinear and linear models showed very high GoF (r2=0.951-0.999; SEE=17-159N). Despite higher GoF for curvilinear models, AIC showed that the linear model presented ~99-100 % chance to be the best one to describe the force-velocity relationship. Conclusion: the force-velocity relationship in acyclic lower limb extensions can be considered as linear from its force (from 5%v0-L) to its velocity end (up to 86%v0-L). Assisted horizontal acyclic lower limb extensions allowed achievement of movement velocities very close to v0, representing an interesting modality for training or testing force production capabilities at high velocities, notably for weaker populations.
Testimony and Narrative of Pahadi’s “The Tears of Terror”
Authors: Pokharel Badri Prasad
Published: May 2021

This paper makes an attempt to analyze trauma and testimony in Kishor Pahadi’s “The Tears of Terror” by applying cultural trauma perspectives. The story has brought some painful experiences of a conflict victim during the ten years Maoist conflict that took the lives of more than seventeen thousand innocent people. This article aims to bring the facts about conflicts and wars which have always brought destruction in human life, and later pain and suffering for those who survived the disaster, but such catastrophes can have a creative dimension upon the victims who have witnessed the events. These painful memories in the form of testimony can be a source for writing narratives which can help one understand history and many hidden facts – emotional attachments of the victims and of the perpetrators, that happened quite long ago. Wars fought in past have been talked about and brought out in narratives for a long time. Narrativizing the past conflict as it was has been considered an important task for writers. Bearing witness to such events and presenting them as testimony has become a crucial task for many literary works.
How to Avoid Human-Animal Dichotomy and Become Ethical
Authors: Kathet Gunja
Published: May 2021

Anthropomorphizing is not simply lending human attributes to nonhuman animals; but in the very act of lending, there is taming and domesticating of animals. This paper in the light of Critical Animal Studies (CAS) argues that the companion/ pet species are the result of  human intervention in the wilderness, taking away the natural life of cats, dogs, horses, and so many others; then, caging or leashing them, thus suspending their rights, even while proliferating their population. While feeding them "properly," proper to human standards, humans have weakened the pet species' immunity and aggravated their vulnerability. Since it is, at the end, for the pleasure and wellbeing of human, anthropomorphism is also anthropocentrism.

Inter-religious Harmony between Hindu Muslim Groups in Nepal
Authors: Ojha Niranjan
Published: May 2021

Religious harmony is very important to maintain peace and stability in a country like Nepal where people are multi-religious. Failure to address religious harmony it could take the society into conflict. Though Nepal is a Hindu dominant secular country the Muslims are an important and inseparable part of Nepalese community. They have been living in Nepal since last 500 years with religious harmony. During this period there were negligible religious riots between Hindu and Muslims. Social acceptance and recognition given to the Nepali Muslims, they were integrated in such a way, became inseparable part of the society. But in recent years they have tried to differentiate themselves religiously challenging centuries old harmony and peace. In the process they have undergone a process of political Islamization and have emerged as a distinctive ethnic community. It has shown a danger of deadly encounter between Hindu-Muslim religion groups. This paper tries to discuss the fundamental factors contributing to religious in a multi-religious society. FGD and library research method is used in addressing the situation of religious harmony. This paper also emphasizes that elements such as acceptance, understanding, co-operation as well as right and justice are significant elements in sustaining religious harmony. Hence, the discussion is aimed to build a sustainable concept of multi-religious harmony in Nepal. The findings could encourage maintaining strong relationship among them.
Effects of Domestic Debt on Interest Rates in Nepal
Authors: Timseena Vishnu Prasad
Published: May 2021

Domestic debt has greater implications on macroeconomic stability and growth. Domestic borrowing can lead to crowding out effect, which can lower the economic growth. In this regard, the study of interest rate effect of the domestic borrowing would be useful to the policymakers and other researchers as well. The time series techniques are used to analyze the relationship between the domestic borrowing and interest rate based on annual data for the period 1990-2020. The empirical study reveals that, despite a positive relationship between domestic borrowing and interest rate, the relationship is insignificant and very weak. This implies that increase in domestic borrowings may not result in an increase in interest rates. This is mainly on account of prevailing administered interest rate on long term bond, dominance of fiscal policy in determining the interest rate of auction, lack of investment friendly environment to private sector, high level of liquidity in the economy, information asymmetry problem and many other problems.

Muna, the female protagonist of the epic poem “Muna Madan”, suffers from prejudices. She becomes the victim of patriarchy. Her effort to resist the imposition of masculinity upon her has been useless ultimately. This paper explores how she appropriates the imposition of masculinity and gives consent to her husband to leave for Tibet. While doing so she remains at home nursing his aged mother, waiting, hoping for his safe return that never materializes until she transforms her from her physical state to the spiritual one.
Beyond the Carceral #MeToo
Authors: Pratihar Ananya Roy , Das Saswat Samay
Published: May 2021

In this article, we attempt a radical critique of the #MeToo movement. We do not aim to display #MeToo phenomenon as a molarity anchored to the nobility of its supposed historical origin. Rather we showcase it as a nomadological flow. This is a flow that, on the one hand, resonates with and folds the productive intensities of its supposed historical origin. But, on the other hand, it turns into a dangerous mad line of flight with a potential to stultify the relational dynamics of genders. Secondly, we will argue that what lies behind the metamorphosis of ‘Me Too’ activism into a dangerous line of flight, inclined to devilishly restructure the socius, is its precarious connection with the elusive media images. Thirdly we shall show how as a dangerous line of flight #MeToo activism ends up becoming an ally of neo-liberal carceral feminism and governmental schemes of incarceration and surveillance. And finally, we will focus on explaining the positionality of #MeToo in the light of schizo-aesthetics of body and desire.

Here is studied the capillary penetration of a viscous liquid between two vertical, rectangular close together plates. In experiments the plates were joined simultaneously along two edges, and the liquid has penetrated from the bottom. Spacers with different geometries like circular, triangular and rectangular shape, were used to check their aects on the rise proles in a dynamic way, it was noticed that  when time evolves, the proles are stabilized in a catenary and the instabilities induced by efforts present in the plates disappear. Also, it is observed a rate of ascent that diers of classical values of t^1/3 or t^1/2, depending of gravity effect.
On a general correlation for the discharge rate of grains through slots in sidewalls of silos due to gravity

In this work we discuss the general validity of a phenomenological correlation for the mass flow rate of dry non cohesive granular material that outflows, due to the gravity, from slots in very thin vertical sidewalls of bins. The correctness of such a formula is analyzed by comparing it to other correlations published elsewhere which reports cases of very large, similar and very small channel width W relative to its length D.
Plane waves reversibility
Authors: Baldwin G.
Published: May 2021

This work simulates reversibility of plane waves in different ways. We start making theoretical classical reversing of a plane wave in two different ways exchanging t by –t as first step. In one case, we additionally flip the temporal orientation of the magnetic field. In the other case, we flip the electric field. Therefore, we can compare two classical approaches to time reversed electromagnetism on plane waves. On the other hand, we obtain two different mechanically reversed plane electromagnetic waves out of the frame of the electromagnetics reversibility theory. A theoretical experiment makes these effects, where, an infinite plane current generates two plane waves in opposite directions. After this, the waves are made to return by two different ways: (1) by retro reflecting and (2) by moving back the wave. Finally, the returning plane waves insides over a conductor plane in order to induce plane currents in the conductor. The goal is to complete reversibility cycles including the charges movement. The returning waves and the induced currents will be compared themselves in all the cases. Charges movements are also included in the discussion in order to have an additional felling of the waves reversibility and physical insight of time-reversed waves.  It is used a plane waves theoretical experiment created by Feynman as a starting point [1]
Retarded hydrodynamic fluctuations effects on the light scattering spectrum and elastic moduli of a linear viscoelastic liquid
Authors: Rodríguez R. F. , Rodríguez E. Salinas , Camacho J. F.
Published: May 2021

Fluctuating hydrodynamics (FH) is one of the theories that describes the dynamics of the fluctuations for fluids at mesoscopic scales. However, it is only valid for Markovian processes. Here we extend this approach for a viscoelastic liquid by using a generalized Langevin equation (GLE). We obyain general analytic expressions for the density fluctuations correlation function, the dynamic structure factor and the light scattering spectrum. In particular, we calculate the intermediate scattering function when the time memory and the noise correlation function are power-laws. We find that the difference in values of this quantity as functions of the viscoelasticity may be ∼62% and might be measurable.
Ajuste de resonancia doble en láseres de Brillouin de fibra óptica
Authors: Spirin V. V. , López Mercado C. A. , Bueno Escobedo J. L. , Fotiadi A. A.
Published: May 2021

Reportamos una solución técnica simple para un ajuste preciso de la longitud de cavidades cortas de fibra óptica usadas comúnmente en los láseres de Brillouin. La cavidad ajustada del láser es simultáneamente resonante para el bombeo y la emisión de Stokes. La técnica propuesta está basada en registrar la respuesta de Brillouin de la cavidad a un escaneo frecuencial de la emisión del láser de bombeo. Las trazas almacenadas son utilizadas para calcular el exceso de longitud de la cavidad que necesita ser removido de la cavidad original para un ajuste preciso de la resonancia de Brillouin en cualquier longitud de onda preseleccionada del láser de bombeo. Para la comprobación de su funcionamiento se desarrolló el ajuste fino de una cavidad de anillo basada en fibra estándar SMF-28 de Corning de 4 m de longitud. Además, se presenta un análisis detallado del error en el algoritmo de ajuste de la doble resonancia en la cavidad de anillo de fibra del láser de Brillouin de corta longitud. La propuesta presentada es igual de útil para el diseño de láseres de fibra monomodo de espectro óptico ultra-angosto y láseres de fibra de Brillouin Q-switched, así como para aplicaciones que emplean alta potencia en cavidades de fibra que evitan la dispersión de Brillouin estimulada. We report a simple technical solution for precise adjustment of short fiber cavities commonly used with Brillouin fiber lasers. The adjusted laser cavity is simultaneously resonant for pump and Stokes radiations. The technique is based on recording the Brillouin response of the cavity to the frequency scanned laser radiation. The recorded traces are used to calculate the excess cavity length that needs to be removed from the original cavity to provide its precise adjustment to the Brillouin resonance at any preselected pump laser wavelength. For demonstration of the approach, fine adjustment of a 4 m long ring cavity based on standard Corning SMF-28 fiber is performed. A detailed error analysis of the algorithm for adjustment of double resonance in short-length Brillouin ring fiber laser was presented. Demonstrated approach is equally useful for the design of single mode fiber lasers with ultra-narrow optical spectra, Q-switched Brillouin fiber lasers as well as for applications employing high power fiber cavities free from stimulated Brillouin scattering.

Correlation technique using of-the-shelf CW DFB laser for interrogation of fiber optic sensors
Authors: Shlyagin M. G. , Arias L. A. , Lopez Rivera Jorge H.
Published: May 2021

The paper presents a simple fiber-optic sensor technique based on methods of correlation optical time domain reflectometry. A correlation reflectometry technique can measure distribution of reflection coefficient along the optical fiber by calculating the correlation function between a probe optical signal (reference) and the signal returned back due to reflections or/and back-scattering from the fiber under the test. To obtain the best sensor performance, the probe signal power should be a truly random function of time. As an optical source we use a free-running DFB laser diode operating in a continuous wave regime without any external modulation. To generate the probe test signal, laser light is passed through an interferometer with an optical path difference much longer than the coherence length of the laser light. The light intensity at the interferometer output has a truly random fluctuations and its auto correlation function is suitable for correlation optical reflectometry. We present results of experimental verification of the techniques in different sensor configurations.

Introduction: Prostate cancer is among the most common malignancies. Despite the high prevalence and importance of prostate cancer, the molecular mechanisms underlying its development and progression remain poorly understood.Materials and Methods: This cross sectional study was conducted on 50 cases of prostatic carcinoma with different Gleason score referred to Sina hospital in Tehran in Iran in 2016. The gene expression was assessed by using the immunohistochemistry staining and PCR technique. Result: The presence of neoplasia on prostatic biopsy induced strong staining and increased in mRNA level of COX-2 expression when compared to normal tissue (P-Value >0.05). The expression is not well associated with different Gleason grades of prostatic carcinoma. Conclusion: The expression of COX-2 protein by immunohistochemistry staining and PCR technique in our study offers the valuable diagnostic information. Thus, we think this marker might be studied in larger series of patients for its further validation as diagnostic factor in prostate biopsies.

Aim and objectives: Diagnostic accuracy of post therapy Papanicolaou (pap) tests is low, as it is difficult to differentiate benign from malignant lesions due to post radiation cellular changes. Here we have evaluated the role of biomarker p16INK4a and Ki67on conventional cell blocks (CCBs) in post therapeutic surveillance of cervical cancer to detect residual disease and site recurrence. We have also evaluated CCBs as a primary screening test. Material and Methods: In this cross-sectional study, patients who were diagnosed as cervical cancer before one year were followed between periods of April 2018-April 2019. We collected conventional pap smears and samples in 10% neutral buffered formalin for CCBs. The immunohistochemistry was performed on all cell blocks using Ki67 and p16INK4a as primary antibodies.Results: Out of total 35 cases, recurrences and residual disease were diagnosed in 8 cases. Sensitivity, specificity, diagnostic accuracy for pap, cell blocks and p16INK4a for detecting cervical cancer were 75%, 74.07%, 88.57%; 100%, 88.89%, 91.43% and 37.50%, 96.30% and 82.86% respectively. We observed that Ki67 labeling index ≥ 20% had a diagnostic accuracy of 100%. Conclusion: Our findings suggest that Ki67 labeling index ≥20% on CCBs can differentiate residual and recurrent cancer from post radiation dysplasia in post therapy surveillance cytology (p value <0.001). We also observed that CCBs has better diagnostic accuracy than pap test (Mac Nemar p value, 0.027). We did not found p16INK4A much useful as a biomarker in evaluation recurrence/residual disease.

Abstract:  In the field of shipping, maintenance of ships needs to be done to maintain the durability of the ship so that the life time is long so that the level of smooth productivity is not disturbed due to damage to the ship. Apart from that, regular surveys are also conducted to check the condition of the ship as well as to collect data on ships in the class. Ship maintenance in ensuring the implementation of the planned maintenance system (PMS) on the ship must meet the requirements. The survey studied in this study is about maintenance methods that are considered inaccurate in selecting the method of maintaining machinery and not applying a management which has an impact on work effectiveness. The research method used is a periodic survey method accompanied by implementing a Maintenance Management System tailored to the needs of the company. So that there are two main studies, namely the Annual Survey System and the Intermediate Survey System. This is to determine the right method for the company in calculating in terms of material, cost and time as well as maintenance management for each activity in order to create more effective work.Abstrak: Pada bidang perkapalan perawatan kapal perlu dilakukan untuk mempertahankan ketahanan kapal agar life time nya lama sehingga tingkat produktifitas lancar tidak terganggu akibat adanya kerusakan pada kapal. Selain itu juga dilakukan survey secara berkala untuk pengecekan kondisi kapal sekaligus pendataan kapal pada kelas.  Perawatan kapal dalam menjamin terlaksananya pelaksanaan sistem pemeliharaan terencana (PMS, Planned Maintenance System) di kapal harus memenuhi persyaratan. Survey yang dikaji dalam penelitian ini adalah mengenai metode pemeliharaan yang dianggap belum tepat dalam pemilihan metode pemeliharaan machinery dan tidak diterapkanya sebuah management yang berdampak kepada efektivitas kerja. Metode penelitian yang digunakan adalah metode survey periodik disertai dengan menerapkan Maintenance Management System yang disesuaikan dengan kebutuhan perusahaan.

The study aims to explore different types of agricultural practices including the shifting and the settled cultivation practices of the Kondhs in Kandhamal district in Odisha. The author attempts to understand their traditional beliefs, perception, rationality and knowledge in agricultural practices. Besides, the author briefly focuses on the issue of transformation in traditional agriculture, opportunities and challenges. The nature of the research is purposive and exploratory and is based on grounded theory. Field observation, household schedule and focus group discussions were employed for primary data collection. For information about indigenous knowledge, mainly elderly people were interviewed. The Kondhs’ traditional agriculture has a strong cultural and ecological foundation. The community is not short of innovation. With the blend of both perception and rationality the traditional agricultural practice of the community continued for generations, but now in transition. Therefore, this practice needs to be protected from its potential threat of extinction.
A SOCIO-COGNITIVE STUDY OF ETHNOCENTRIC DISCOURSE IN LYNN NOTTAGE’S SWEAT
Authors: Bayat Sanaz , Hadaegh Bahee
Published: May 2021

Being some major problems of our contemporary world, racism and ethnocentrism demand persistent critical scrutiny. One oft-neglected aspect of these problems is how such prejudices are shared and communicated among the members of the dominant group. This study examines Lynn Nottage’s Pulitzer Prize-winning play, Sweat (2015), as a dramatic representation of how racism and ethnocentrism are reproduced and communicated as a social cognition. To this aim, the study tries to employ Teun Adrianus Van Dijk’s cognitively-based discourse analysis and focus on some micro-level aspects of racism as a social cognition rather as an abstract historical phenomenon. Contextualizing the play within its socio-historical moment, three trends of schematic attitudes and mental models regarding ethnocentrism_ as Van Dijk’s theory outlines_ are identified from and studied in the play. The findings demonstrate the socio-cognitive dimension of the discourse of racism, particularly the way it is reproduced and communicated among the dominant in-group members. Moreover, the discussion offers some insight on Lynn Nottage’s latest dramatic endeavor in a hard-hitting portrayal of the intersections of race, class, and political economy and in drawing attention to the real meaning of diversity and inclusion in contemporary America.
RETHINKING LANGUAGE AMBIGUITY BEYOND THE SEMANTICO-PRAGMATIC INTERFACE
Authors: Belfarhi Khadija
Published: May 2021

Ambiguity occurs when the language user intends unspecific and unclear meaning through written or spoken language. It has been approached by semantics, pragmatics and philosophy of language because indeterminate meaning needs a mechanism that assembles the right attributes for decreasing ambiguity. In that, such a mechanism acts away from the structural conditional which was for long thought applicable for clarifying meaning. An extension in the semantic-pragmatic mechanism is needed as far as the latter fails to account for indeterminate meaning. The present paper suggests a more interactional mechanism that integrates two components. The former relies on the linguistic resources that act as possible attributes including both the semantic and pragmatic. The second, however, is the free component wherein the analyst acts in free path that does not necessarily follow the linguistic rules and the fairplay aims at extending the attributes and their interaction. The application of this mechanism has been on a variety of ambiguities ranging from the simplest daily metaphors to the most indeterminate utterances. It has been found that its application succeeds with distanced attributes, as when the utterance's meaning is carried out by another far attribute.
PHRASEOLOGIES WITH ANIMAL NAMES IN ALBANIAN, GERMAN AND ENGLISH: A COMPARATIVE STUDY
Authors: Canaj Kimete
Published: May 2021

Phraseologies with animal names in Albanian, German and English: A comparative study. The paper takes a comparative approach in discussing selected phraseologies with animal names in Albanian, German and English. The point of departure is a collection of 48 random Albanian lexemes and their counterparts in the other two languages. Phraseologies, Metaphor and Translation have a hidden relationship with one another until we explore the linguistic and conceptual roots of these words. To carry something across, and in the case of translation, something is carried over from one language to another; hence to translate. Metaphor, on the other hand, indicates a similar act of transference (Übertragung), as it is a figure of speech in which a word or phrase signifying one thing is used in place of another to suggest some degree of likeness or equivalence. The most interesting result of the comparison is that there are more similarities between the neighbour languages than Germanic languages. This implies that neighbourhood and the common history have more impact on languages, even from different families (Albanian‐German), than common roots (English‐German).
