Internal Barbarism as Factor of Civilisation Decline
Authors: Sulimov Stanislav Igorevich
Published: July 2021

The study aims to determine the essence of internal barbarism and formulate its typology. Novelty lies in identifying the role of internal barbarism in the crisis of the civilised society and its further destruction under the influence of external barbarism. This mechanism operates according to the same principles in any era. As a result of the study, such types of internal barbarism have been identified as the corrupt elite and the impoverished common people consumed with unrestrained acquisitiveness, countercultural movements and revolutionary factions that are unable to accept the existing socio-political order.

Perkembangan kebutuhan interaksi telah menyebabkan perubahan besar dalam cara manusia berkomunikasi. Efek positif keberadaan media tentu menjawab persoalan waktu, ruang serta jarak dalam memenuhi kebutuhan dan menjalin interaksi. Tetapi dalam pandangan kritikal teknologi komunikasi, setiap media membawa efek negatif terhadap penggunanya. Hal ini juga terjadi karena salah menafsirkan trust dalam interaksi, baik distrust dalam menjaga kredibilitas diri dan profesionalitas atau sangat begitu yakin (over trust) kepada media dengan menitipkan pendidikan anak kepada sosial media. Interaksi sosial yang biasanya ada kontak langsung dan komunikasi yang dilakukan secara tatap muka, kini beralih pada pemanfaatan teknologi komunikasi melalui jejaring di dunia maya. Situasi ini menjadi sesuatu yang fenomenal, hingga akhirnya menjadi kebiasaan dalam komunikasi antar remaja. Masa inilah bisa dianggap sebagai masa krisis identitas atau tahapan untuk mencari identitas diri. remaja cenderung mencari tahu banyak hal baru dengan mengeksplorasi dunia maya. Salah satunya adalah keingintahuan remaja mengenai berbagai informasi terkait lingkungannya, khususnya informasi tentang bencana. Sebagaimana diketahui bahwa munculnya bencana alam tersebut memberikan dampak yang cukup dirasakan, salah satunya adalah munculnya korban jiwa , kehilangan materi dan terhentinya kegiatan sekolah. Oleh sebab itu, dengan tujuan untuk mengurangi kerugian baik materi maupun korban jiwa. Maka sangat perlu bagi para remaja untuk mengerti mengenai tanggap bencana.

enyakit Tidak Menular (PTM) sering disebut silent killer karena PTM merupakan penyebab kematian tertinggi sebelum era pandemik. Data di Indonesia menunjukkan terdapat empat penyakit utama PTM yang menyebabkan 60% kematian yaitu kardiovaskuler, penyakit paru obstruksi kronis, kanker, dan DM. Penderita PTM tidak hanya pada lanjut usia, tetapi remaja hingga dewasa pun cukup banyak di Indonesia. Hal ini menjadi ketakutan tersendiri bagi masyakarat setempat, salah satunya pada penderita DM. DM telah diakui sebagai salah satu dari empat penyakit tidak menular utama yang menuntut perhatian segera dari semua pemegang kepentingan nasional secara global dalam upaya untuk mengatasi prevalensi dan komplikasi terkait. Penyakit ini dianggap sebagai 10 penyebab kematian teratas secara global, membunuh sekitar 1,6 juta orang di seluruh dunia dan dipandang sebagai faktor risiko tertinggi ketiga untuk kematian dini di Dunia. Faktor pendorong utama kondisi DM tipe 2 secara global antara lain kelebihan berat badan dan obesitas, gaya hidup menetap dan peningkatan konsumsi makanan tidak sehat yang mengandung daging merah dan daging olahan tingkat tinggi, biji-bijian olahan dan minuman manis. Sebagian masyarakat Indonesia hanya mengetahui jika DM tipe 2 disebabkan karena mengonsumsi karbohidrat terlalu tinggi, sehingga penderita DM tipe 2 biasanya menghindari makanan yang mengandung karbohidrat.

Reformasi Birokrasi Pemerintahan Desa
Authors: suhendar atep
Published: July 2021

Masalah birokrasi di Indonesia akan selalu terkait dengan dua sumber permasalahan yang sangat kompleks. Pertama, permasalahan yang muncul dari faktor internal, dan kedua, permasalahan yang bersumber dari faktor eksternal. Dari faktor internal misalnya, terkait dengan masalah yang meliputi hal-hal seperti kualitas SDM yang dianggap masih rendah, sistem dan prosedur bertele-tele (birokratis), budaya kerja yang feodalistik, kepemimpinan yang kaku dan cenderung tidak visioner, mental dan moral rendah, struktur organisasi yang gemuk tapi kurang jelas fungsinya, serta kesejahteraan pegawai yang rendah. Faktor tersebut menyangkut masalah perilaku administrasi maupun perilaku organisasi. Sedangkan dari faktor eksternal, paling tidak terkait dengan hal-hal seperti kepercayaan masyarakat yang rendah terhadap birokrasi, tuntutan masyarakat terhadap perlunya birokrasi yang profesional, bebas KKN, budaya yang dianut oleh masyarakat umum kurang kondusif bagi perbaikan birokrasi, tingkat kesadaran dan kedisiplinan masyarakat terhadap sistem kebijakan yang berlaku masih rendah, kesenjangan sosial, serta hal-hal lain yang terkait dengan pola, struktur, dan aktivitas publik yang dapat mempengaruhi tugas-tugas birokrasi.
The structure of online social networks modulates the rate of lexical change
Authors: Zhu Jian , Jurgens David
Published: July 2021

New words are regularly introduced to communities, yet not all of these words persist in a community's lexicon. Among the many factors contributing to lexical change, we focus on the understudied effect of social networks. We conduct a large-scale analysis of over 80k neologisms in 4420 online communities across a decade. Using Poisson regression and survival analysis, our study demonstrates that the community's network structure plays a significant role in lexical change. Apart from overall size, properties including dense connections, the lack of local clusters and more external contacts promote lexical innovation and retention. Unlike offline communities, these topic-based communities do not experience strong lexical levelling despite increased contact but accommodate more niche words. Our work provides support for the sociolinguistic hypothesis that lexical change is partially shaped by the structure of the underlying network but also uncovers findings specific to online communities.
What is Theory of Mind? A Psychometric Study of Theory of Mind and Intelligence
Authors: Navarro Ester
Published: July 2021

Theory of mind (ToM) is an essential ability for social competence and communication, and it is necessary for understanding behaviors that differ from our own (Premack and Woodruff, 1978). Recent research suggests that tasks designed to measure the ToM construct might not adequately capture ToM ability (Warnell & Redcay, 2019; Quesque & Rosetti, 2020). This hinders the interpretation of experimental findings and puts into question the validity of the ToM construct. This study examines the structure of ToM, crystallized intelligence (Gc), and fluid intelligence (Gf) to (a) understand whether ToM should be considered a monolithic ability and (b) to explore whether tasks of ToM present adequate construct validity. For this, confirmatory factor analyses (CFAs), exploratory factor analysis (EFA), and exploratory network analysis (NMA) were conducted. The results of the models largely point to the same conclusion: ToM tasks are not purely assessing a single construct. Importantly, these findings align with recent theoretical accounts proposing that ToM should not be considered a monolithic construct (Quesque & Rosetti. 2020; Schaafsma et al., 2015, Devaine et al., 2014), and should instead be explored and measured as multiple sub-components.
Advocating for the use of Restorative Justice Practices: Examining the Overlap Between Restorative Justice and Behavior Analysis
Authors: Pavlacic Jeffrey Michael , Kellum Karen Kate , Schulenberg Stefan E.
Published: July 2021

Broadly defined, Restorative Justice (RJ) is a set of procedures based in Indigenous peacemaking practices that reduces recidivism and guides the effective reparation of harm. RJ practices provide harm-affected parties an opportunity for engagement in the resolution process, which theoretically enhances community well-being. RJ practices overlap significantly with behavior-analytic principles. Implementing RJ practices from a context-focused, appetitive-based approach that focuses on classes of behaviors may address harmful behaviors within police organizations. RJ practices may also facilitate changes in contexts that support behaviors valued by the community. The current review discusses criminal and Restorative Justice, RJ processes and practices, the effectiveness of RJ in various contexts, how RJ overlaps with behavior-analytic principles and existing behavior science models more generally, research suggestions, and recommendations for behavior analysts implementing RJ within police organizations and communities to address officer misconduct.
Intervening on psychopathology networks: Evaluating intervention targets through simulations
Authors: Lunansky Gabriela , Naberman Jasper , van Borkulo Claudia D. , Chen Chen , Li Wang , Borsboom Denny
Published: July 2021

Identifying the different influences of symptoms in dynamic psychopathology models may hold promise for increasing treatment efficacy in clinical applications. Dynamic psychopathology models study the behavioral patterns of symptom networks, where symptoms mutually enforce each other. Interventions could be tailored to specific symptoms that are most effective at lowering symptom activity or that hinder the further development of psychopathology. Simulating interventions in psychopathology network models fits in a novel tradition where symptom-specific perturbations are used as in silico interventions. Here, we present the NodeIdentifyR algorithm (NIRA) to identify the projected most efficient, symptom-specific intervention target in the Ising model. This algorithm is implemented in a novel and freely available R package. The technique studies the projected effects of symptom-specific interventions by simulating data while symptom parameters (i.e., threshold parameters) are systematically altered. The projected effect of these interventions is defined in terms of the expected change in overall symptom activity across simulations. With this algorithm, it is possible to study (1) whether symptoms differ in their projected influence on the behavior of the symptom network, and, if so, (2) which symptom has the largest projected effect in lowering and increasing overall symptom activation. As an illustration, we apply the algorithm to an empirical dataset containing assessments of PTSD symptoms in a sample that experienced the Wenchuan earthquake in 2008. The most important limitations of the method are discussed, as well as recommendations for future research, such as shifting towards modeling individual processes to validate these types of simulation-based intervention methods.
State centrism in International Relations. Strengths and limitations and possible alternatives

Realism, institutional-liberalism and constructivism are state-centric. State formation and consolidation as a unitary actor that concentrates sovereignty, population, territory, autonomy, and authority is a product of modernity. This essay first address how state centrism evolved in the principal theories in IR, then present the strengths and limitations of the state centric approach as a unit of analysis, followed by an analysis of the incorporation of new units of analysis such as transnational networks or subnational actors. Recently, there is a development of new unit of analysis, which shows a flow back where the subnational level and individual levels of analysis influencing international relations.
Gender differences in the aims and impacts of research
Authors: Zhang Lin , Sivertsen Gunnar , Du Huiying , HUANG Ying , Glänzel Wolfgang
Published: July 2021

This study uses mixed methods – classical citation analysis, altmetric analysis, a survey with researchers as respondents, and text analysis of the abstracts of scientific articles – to investigate gender differences in the aims and impacts of research. We find that male researchers more often value and engage in research mainly aimed at scientific progress, which is more cited. Female researchers more often value and engage in research mainly aimed at contributing to societal progress, which has more abstract views (usage). The gender differences are observed among researchers who work in the same field of research and have the same age and academic position. Our findings have implications for evaluation and funding policies and practices. A critical discussion of how societal engagement versus citation impact is valued, and how funding criteria reflect gender differences, is warranted.
Women in mechanics: A study on gender ratio using selected journals from the years 2002 and 2017
Authors: Kaesler Melanie , Leicht-Scholten Carmen , Reese Stefanie
Published: July 2021

Even though there have been efforts for many years now to attract more women to engineering fields, technical professions are still clearly dominated by men. The following study examines the gender ratio concerning authorship within two popular journals in the field of mechanics: Computer Methods in Ap-plied Mechanics and Engineering (CMAME) and Journal of the Mechanics and Physics of Solids (JMPS). The examined periods include the years 2002 and 2017. Beyond that, we paid attention to the individual citations of the articles and the first author’s h-indices as well.In these journals, the percentage of female authors in the field of mechanics is significantly lower than the number of female graduates and doctoral candidates in the field would suggest. Even if there was a slight increase in publications of women in the investigated period, male scientists’ contributions were still dominating the research field of mechanics in 2017.
Akreditasi Perguruan Tinggi dan Kebijakan Merdeka Belajar-Kampus Merdeka: Sebuah Pengalaman dan Harapan
Authors: Wijiharjono Nuryadi
Published: July 2021

The purpose of this article is to reveal the experiences of the higher education accreditation model and expectations of the freedom to learn policy or “Merdeka Belajar-Kampus Merdeka” (MBKM). Indonesia has more than 4000 higher education institutions that are building quality to educate the nation’s life. But only a few of these managed to become centers of excellence. There has been a widening quality gap between universities in Java and outside Java. Without radical policies in the higher education sector, the future of the young generation will be threatened. MBKM policy, with a few notes, can be an alternative solution for the 21st century.
Self-efficacy Beliefs of Early Career Teachers: A Qualitative Exploration from Odisha, India
Authors: Apat Biswajit , Swain Pranaya
Published: July 2021

After the enactment of the Right of Children to Free and Compulsory Education Act, 2009 (popularly called RTE) teachers working in governmental schools in rural areas face the challenge of educating millions of first-generation learners, most of whom belong to socially and economically weaker sections. The education system of India has succeeded to some extent in enrolling these students in accessible schools. The quality of education provided in government schools, however, still remains a matter of concern. As reflected in several studies, most students do not have grade-specific learning levels. In popular discourse teachers are held responsible for the deteriorating condition of government schools. Usually portrayed as poorly-trained, frequently absent, work-shy, hard-to-please, and occasionally corrupt, teachers are going through a kind of identity crisis in contemporary India. Thus, on the one hand, we have the “quality problem”- the learning crisis prevalent in elementary schools, and on the other hand we have the “teacher problem”- the popular perception that the performance of teachers in government schools is substandard. These two sets of problems are entangled in such a way that one cannot to be addressed without grappling with the other. This paper seeks to explore efficacy beliefs of teachers. Previous research on teachers’ efficacy beliefs suggests that teachers with high sense of efficacy are likely to perform better than teachers with low self-efficacy. The strength of efficacy beliefs is also positively correlated with students’ learning levels. The data suggest that the participants of this study feel confident of their effectiveness but they do not refer to students’ learning outcomes while evaluating themselves as teachers. The source of their efficacy beliefs lies in their familiarity with students, experience of positive behavioural change in students and their own personality traits.
Making the ‘Harm Principle’ Central to Approaches Against Information Disorder
Authors: Omoregie Uyiosa
Published: July 2021

Misinformation online is an urgent global challenge. The gravity of the challenge, and its effect on global collective behaviour, has led to calls for social media/information disorder to be designated a “crisis discipline” like medicine, conservation biology and climate science. Scholars have generally settled for a definition of ‘information disorder’ that reveals three variants: misinformation, disinformation and malinformation. What should be of paramount importance, in the fight against information disorder, is the potential of falsehood to cause harm. This potential for harm must be the litmus test distinguishing free speech and speech that should not be free. The ‘harm principle’ proposed by John Stuart Mill is more than 150 years old and needs an upgrade for the social media age. One such upgrade is proposed by Cass Sunstein. We summarize different approaches to analysing online information disorder. We conclude that approaches which emphasize analytical and critical thinking are important but have shortcomings. When analysing complex phenomena like conspiracy theories a ‘systems’ approach is more effective to reveal root causes of information disorder, provide actionable insight and long-term solutions.
Everyday Aesthetics, Space, and the Sensory: Fear of Crime and Affect in Inner Sydney
Authors: Lee Murray , Ellis Justin R , Jackson Jonathan
Published: July 2021

In this paper we explore some pre-conscious aesthetic and sensorial aspects of affect in fear of crime. Drawing on data from focus groups undertaken in inner Sydney, Australia, we link the sensory and aesthetic preconditions of fear of crime to its affective, behavioural and cognitive elements. We argue that fear is grounded in the structural, personal and inter-subjective components of individual’s lives and their interaction with physical and social environments, which then influence how individuals cognitively understand their own risks and react behaviourally to these emotional responses. By bringing alive the importance of environmental cues and the cultural and structural positions of those who are likely to frequently worry about victimisation, we hope to provoke a minor reassessment of, and encourage more focus on, fear’s sensory and aesthetic origins.
Blurring Genres and Violating Guild Norms A Review of Reviews of The Age of Surveillance Capitalism
Authors: Jansen Sue Curry , Pooley Jefferson
Published: July 2021

In this essay—a review of the reviews of Shoshana Zuboff’s The Age of Surveillance Capitalism (2019)—we ask whether the published reactions to Zuboff’s tome say something about the legibility problem. After reading them all, we came to wonder if the reviews themselves construct an additional hurdle to knowing Google, Facebook, and the rest: the Babelist din of competing knowledge cultures. With so many distinct dialects, the project of general understanding might be hobbled from the start.
Mothers and Mobility: a Re-examination of (Trends in) Intergenerational Mobility in the UK
Authors: Opacic Aleksei
Published: July 2021

Existing research on intergenerational class mobility typically uses either fathers’ occupa- tion, or the occupation of the ‘class dominant’ parent, as an indicator of ‘class origin’, ignoring heterogeneity in mothers’ and fathers’ class effects on children’s mobility outcomes. Such an elision therefore misses how class reproduction may be shaped by gender in important ways. In this paper, I bring new empirical evidence to the role of mothers in intergenerational mobility in Britain for birth cohorts born in the latter half of the 20th century. I find a significant inde- pendent effect of mothers’ class on individuals’ class destinations, and evidence that fathers’ and mothers’ class positions show a stronger effect on same-gender children. Further, mothers and fathers’ class effects do not show similar trends across cohorts; while fathers’ effects have weakened for women but stayed constant for men, mothers’ effects have weakened for both men and women. My findings highlight the importance of taking a gender-sensitive approach to the study of intergenerational mobility patterns and trends.
Anthracite as filter Media in Filtration Process
Authors: Poudel Aashish
Published: July 2021

This research was carried out to see the performance of anthracite as filter media in filtration process. The study also aimed to compare two filter media in terms of turbidity it removed, head loss development with time and filter run with increase in influent turbidity. Two rapid gravity filter(RGF) columns were prepared having internal dimensions of 11x11x290 cm3, one with anthracite and another with sand as filter media. The uniformity coefficient of sand and anthracite of 1.54 and 1.4 were maintained from sieve analysis. Constant Filtration rate of 3m/h was set and other ancillary activities were made same for both filter models. The experiments were repeated seven times with different influent turbidity ranges of 0-25, 25-50, 50-100, 100-150, 150-200, 200-250, 250-300 NTU. Both the Filters were back washed with back washing velocity of 24 m/h, when the terminal head loss of 165.4 cm was obtained. The effluent quality of anthracite obtained was better for all the filter run. The head loss development with time was more for sand filter in all filter runs. The filter run time for sand vary from 150 to 8 hours and for anthracite, it varies from 172 to13 hours from first to seventh filter run.
Public Transportation Energy Planning by Network Analysis-A Case Study of Kathmandu Valley
Authors: Bajracharya Aprin , Nakarmi Amrit Man
Published: July 2021

This paper is an attempt to find out the required optimum number of vehicles in the Top Ten Routes of Kathmandu Valley which was found from the 163 number of routes of our study on the basis of total travel demand measured in passenger-km per year. The transportation optimization model has been prepared on the Microsoft-Excel Spreadsheet & the optimization of distribution of vehicles is done by using Premium Solver. The results clearly show that the requirement of buses at some routes was less than the available buses plying on the route & the requirement of buses at some routes was more than the available buses plying on the route. The optimization is done on the basis of least cost methods fulfilling the travel demands of flow of passengers at different interval of time in a day at each route of our study. More number of required vehicles in the optimized scenario in the route means more transportation cost, more energy consumption & more environmental emissions than the present scenario & Lesser number of required vehicles in the optimized scenario in the route means lesser transportation cost, lesser energy consumption & lesser environmental emissions than the present scenario.
Numerical Simulation Studies on Stall Suppression of a NACA0015 Airfoil
Authors: Shrestha Biswash , Bhattarai Nawraj
Published: July 2021

This study aims to achieve an improved airfoil performance at low Reynolds number, and to determine the optimum position and size of rectangular cross-section burst control plate (BCP) to suppress stall in airfoil. The type of airfoil used in the present study is NACA0015 (National Advisory Committee for Aeronautics) airfoil with 200 mm of chord (c) length. Here, rectangular cross-section burst control plates with different sizes and at different locations are investigated numerically at the low Reynolds number of 1.6×105. Total of three positions (0.05c, 0.1c and 0.2c from the leading edge of airfoil), and four sizes (with heights 0.3 mm, 0.7mm, 1mm and 1.5 mm, and constant width 4 mm) of rectangular BCPs are simulated in ANSYS Fluent software using Transition SST model. The results indicate that the rectangular cross-section burst control plate is an effective device in the suppression of airfoil stall. For 0.7 mm and 1 mm height BCPs, the stall angle is postponed by 2° for all positions, while for 0.3 mm and 1.5 mm height BCPs, the reduction in sudden fall of lift can be observed but at the cost of reduction in maximum lift coefficient. Among various configurations, the 1mm height BCP located at 0.2c position is found to be most effective in the suppression of stall.

The aim of the maximum network flow problem is to push as much flow as possible between two special vertices, the source and the sink satisfying the capacity constraints. For the solution of the maximum flow problem, there exists a number of algorithms. The existing algorithms can be divided into two families. First, augmenting path algorithms that satisfy the conservation constraints at intermediate vertices and the second preflow push relabel algorithms that violates the conservation constraints at the intermediate vertices resulting incoming flow more than outgoing flow.In this paper, we study different algorithms that determine the maximum flow in the static and dynamic networks.

Authors: Kafle Mukesh Raj
Published: July 2021

This paper presents a numerical simulation of recirculating flow patterns in groyne fields. Moreover, it entails the concept determination of proper spacing of vertical unsubmerged and impermeable groynesin seriesto control the bank erosion. Flow pattern between the groynes varies along their space. The flow in groyne field may significantly affect the flow change, bed change, bank erosion and condition of habitat. In this regard, an assessment of flow along the space of groynes will yield important data needed to diversify the object of groyne installation. So, knowledge about determination of the proper spacing of groynes in groyne field is important. Space of vertical groynes was set from 1.5 to 10 times the length of groynes. The velocity field between groynes was simulated by using Computational Fluid Dynamics (CFD) model Nays 2D. Simulated velocity field was compared with existing experimentaldata for the same parameter, which agreed satisfactorily. Based on simulated results,the optimal spacing of vertical groynes to control the bank erosion was recommended.

This study aims to analyse energy scenarios of Bhaktapur Municipality through primary data survey of 165 houses as a function of household's characteristics. Three scenarios are considered business-as-usual (BAU), Sustainable Energy scenario (SED) and Accelerated Growth Scenario (AGS). BAU, SED and AGS show an expected energy growth at annual rates of4.08%, 3.71% and 4.01%; with economic growth of 4.6%, 7.0% and 9.2% respectively. Whereas, the electricity consumption per household in the SEDand AGS are 3,840KWh and 4,698KWh respectively, lies in tier-5 as per SDG. Fuel imported cost NRs. 471 million and NRs. 523 million can be saved in SED and AGS Scenarios respectively as compare to BAU scenario. Overall, under all three scenarios, it was found that total GHG emission in 2018 was 7.59 kilotons to nil in 2030 for SED and AGS.Furthermore,NPV value in AGS and SED scenarios are in negative value which means both scenarios is economically viable.

The global shifting away from petroleum fuels and towards more renewable energy sources has resulted in a significant progress in favor of vehicle electrification. The uptake of electric vehicle in the existing fleet of vehicles has positive impacts in the reduction of emissions and reduces the carbon footprints by moving in to greener transport. Nepal is a hydropower resource rich developing country; it can use its clean source of hydroelectricity for public transport electrification. Use of hydroelectricity for transport electrification can help to reduce the dependence on petroleum fuels with significant environmental benefits. This study aims to analyse energy scenarios of Hetauda through primary data survey of 4086 three wheeler as 1874 and 2212 as gasoline and electric respectively. Three scenarios are considered business-as-usual (BAU), ETRM 100 (100% electric tempo replacement)and ETRM 75 (75% electric tempo replacement). Energy demand of Hetauda is 230.4TJ and will be increased to 333.5TJ for the accounting year 2018 and 2035 respectively.

Kathmandu is Rapidly growing city where the Crisis due to centralization is foreseen in Transportation sector due to lack of proper Planning and Vision prior of establishing settlement. The Current status of Transportation system in Kathmandu is quite alarming in absence of well-organized Public Transportation system. The growth of Vehicles and simultaneously lack of improvements of existing facilities and traffic management have resulted in unorganized improvement of Traffic thereby increasing congestion, accidents and decrease in vehicle speed affecting road capacity. So using managed Scientific system to decrease jam causing parameters with most planned system and replacing the existing Systems by modern facilities, the problem can be reduced. Introduction of Bus rapid transit by gradual replacement of old transportation systems by providing a bus lane can be promising remedial measure to optimize public transportation system in Kathmandu valley

To accommodate the shear requirement and settlement requirement of high rise construction, the concept of piled-raft foundation has been developed. This research deals with successive analysis of parameters of piled-raft foundation system using PLAXIS-2D as a FEM tool. Plain strain analysis of piled raft foundation system has been conducted out by successive fixing up of parameters. For the analysis two cases has been studied for piled-raft lying on silty soil deposit and on clayey deposit with respect to uniform static loading from superstructure. The result of successive variation of parameters showed that variation has limiting effect on stress and displacement behavior. The analysis is also performed for raft of different relative stiffness and pile of different relative compressibility and load sharing between plain strain pile and raft has been analyzed.

Construction labor productivity is the most determinant of success of any construction project. Labor is considered as more variable and unpredictable cost component for the successful accomplishment of construction projects. The main aim of this research is to develop an artificial neural network (ANN) model to predict the production rate for brick masonry work by assessing the various factor affecting labor productivity. Out of forty-four factors selected from a literature review, the top thirteen factors were selected for model development after the questionnaire survey and ranking them based on Relative Importance Index (RII). The model was developed in Neurosolution version 7.1.1.1 using the various input data set collected from active construction site of brick masonry. 65% of data set were used for training, 20 % of data set were used for cross-validation and remaining 15 % of data set were used for testing. The error between actual productivity and estimated productivity was computed using Mean Square Error (MSE) which was 0.019 which verified that the estimated production rate was within an acceptable range. After the successful testing of model, a sensitivity analysis was performed to analyze the order of most influencing factors affecting labor productivity. The developed ANN model can be used for estimating the labor productivity of brick masonry work for any building construction project by incorporating the influence of selected parameters or factors.
