A Comparison of Model-Based and Design-Based Impact Evaluations of Interventions in Developing Countries

There is a long-standing debate as to whether nonexperimental estimators of causal effects of social programs can overcome selection bias. Most existing reviews either are inconclusive or point to significant selection biases in nonexperimental studies. However, many of the reviews, the so-called between-studies, do not make direct comparisons of the estimates. We survey four impact studies, all using data from development interventions that directly compare experimental and nonexperimental impact estimates. Our review illustrates that when the program participation process is well understood, and correctly modeled, then the nonexperimental estimators can overcome the selection bias to the same degree as randomized controlled trials. Hence, we suggest that evaluators of development programs aim to be careful and precise in the formulation of the statistical model for the assignment into the program and also to use the assignment information for model-based systematic sampling.
Innovative behavior of bitcoin market agents during COVID-19: recurrence analysis

The relevance of the research subject is explained by a fundamental change in the conditions of existence and development of agents of the digital economy, limited knowledge about their behavior under conditions of quarantine restrictions. The aim of the research is to study the series of the dynamics of the price of bitcoin and the frequency of online requests for bitcoin as an indicator of the behavior of agents of the digital economy using the methods of qualitative recurrent analysis. The types of constructed time series plots of the price of bitcoin and the frequency of requests for bitcoin are defined as drift with a superimposed linearly gradually increasing sequence, which indicates the unpredictability of the behavior of digital economy agents with a gradual stabilization in new quality trend. The scientific novelty of the research results lies in the proven connection between the series of bitcoin price dynamics and the frequency of online requests for bitcoin, tracking changes in the behavior of digital economy agents before and after the introduction of quarantine restrictions. The procedure for conducting a qualitative recurrence analysis of the series of dynamics is generalized, which takes into account the specifics of the formation of the frequency of online requests for bitcoin, the price and the behavioral aspect of its formation. The practical value lies in defining the characterization of the behavior model of digital economy agents under conditions of quarantine restrictions. The behavior of digital economy agents in the context of COVID-19 requires further research, in particular, using cross-recurrent analysis methods.
Changes of Polyphenol Oxidase Activity of Banana (Musa sapientum L.) Fruits during Ripening Treatment by Ethylene

Changes of polyphenol oxidase (PPO, o-diphenol : oxygen oxidoreductase, EC. 1. 10.3. 1) activity of banana (Musa sapientum L.) fruits during ripening treatment with and without ethylene were determined. The total and soluble PPOs of pulp, which were extracted with and without detergent (Tween 80), were about 100 and 2 unit/g fresh weight, respectively. Both total and soluble pulp PPOs were remarkably increased and showed a maximun peak like a climacteric peak of respiration during the ethylene-ripening treatment. However, in the non-treated fruits, both total and soluble pulp PPOs changed a little during the treatment. In banana peel, total and soluble PPO were about 110 and 0.7 unit /g fresh weight, respectively. Both total and soluble PPO activities of peel were little affected by the ethylene-ripening treatment. These results suggested that the banana PPOs were mainly presented in pulp and peel as a “latent form”, and only “soluble pulp PPO” was affected by ethylene-ripening treatment.
Constraining convective regions with asteroseismic linear structural inversions

Context. Convective regions in stellar models are always associated with uncertainties, for example due to extra-mixing or the possible inaccurate position of the transition from convective to radiative transport of energy. These have a strong impact on stellar models and their fundamental parameters. The most promising method to reduce these uncertainties is to use asteroseismology to derive diagnostics probing the structural characteristics of these regions. Aims. We wish to use custom-made integrated quantities to improve the capabilities of seismology to probe convective regions in stellar interiors. We hope to increase the number of indicators obtained with structural seismic inversions to provide additional constraints on stellar models and the fundamental parameters determined from theoretical modeling. Methods. First, we present new kernels associated with a proxy of the entropy in stellar interiors. We then show how these kernels can be used to build custom-made integrated quantities probing convective regions inside stellar models. We present two indicators suited to probe convective cores and envelopes, respectively, and test them on artificial data. Results. We show that it is possible to probe both convective cores and envelopes using appropriate indicators obtained with structural inversion techniques. These indicators provide direct constraints on a proxy of the entropy of the stellar plasma, sensitive to the characteristics of convective regions. These constraints can then be used to improve the modeling of solar-like stars by providing an additional degree of selection of models obtained from classical forward modeling approaches. We also show that in order to obtain very accurate indicators, we need l = 3 modes for the envelope but that the core-conditions indicator is more flexible in terms of the seismic data required for its use.
Bullying prevention in a Swedish municipality: Supported decentralised reasoning

The national context of Sweden is particularly illustrative for international research, in that bullying and degrading treatment have been a central aspect of policy-making for some time. In Sweden, schools and municipalities are obliged to produce detailed action plans to counteract bullying. The aim of this study is to describe and analyse how practitioners in schools, during implementation of the Municipality Bullying Prevention Model (MBPM), change the way they work and apply decentralised reasoning to prevent bullying. This study makes use of an action-research approach. In the project, bullying prevention is addressed by the participating schools. The findings indicate that practitioners introduced various measures in different places and at different levels during implementation of the MBPM. It also became apparent that bullying prevention work needs to build on a school’s contextual knowledge and have a whole-school approach.
Integrating HRM and Leadership: A Proposed Framework for Effective Leadership in Contemporary Organization

Despite the bulk of studies in the domain of leadership, there is still a dearth of agreement over what makes leaders effective. The objective of the present study is to address this gap by devising a model for leadership effectiveness in light of previous studies. The basic premise of the framework presented in this study is the same as Contingency leadership theory (Fiedler, 1964; 1967). To be successful, managers need to implement different leadership styles in different situations and that a particular leadership style would be most effective in specific circumstances. It is proposed that managers need to implement transactional or transformational leadership style and adopt associated HRM practices depending upon the level of LMX relationship which might lead to effective leadership in an organization. Effective people management requires that HR practices should be applied by a manager with a matching and consistent leadership style. Leadership effectiveness is enhanced if a manager uses a leadership style with supportive HR practices that best matches a particular group of subordinates. Moreover; uncovering the underlying relationship between HRM and leadership will help refine current methodological approaches in this area, guiding theoretical improvement and policy development related to HRM and leadership.
Comparative Housing Research

Abstract The paper reviews major examples of comparative housing research which have been published in the last twenty years and suggests that the dominant approach — grounded in pluralism and convergence theory — which they exhibit is inadequate. Future studies need to be both more detailed and wider in scope, examining the dynamic of the interrelations between the institutions and the social forces involved in the provision of housing. Such a perspective is briefly developed and related to current developments in the housing markets and policies of some advanced capitalist societies. The paper concludes with a discussion of some of the practical problems of cross-national housing research.

The USP 7 / Dnmt 1 complex stimulates the DNA methylation activity of Dnmt 1 and regulates the stability of UHRF 1

Aberrant DNA methylation is often associated with cancer and the formation of tumors; however, the underlying mechanisms, in particular the recruitment and regulation of DNA methyltransferases remain largely unknown. In this study, we identified USP7 as an interaction partner of Dnmt1 and UHRF1 in vivo. Dnmt1 and USP7 formed a soluble dimer complex that associated with UHRF1 as a trimeric complex on chromatin. Complex interactions were mediated by the C-terminal domain of USP7 with the TS-domain of Dnmt1, whereas the TRAF-domain of USP7 bound to the SRA-domain of UHRF1. USP7 was capable of targeting UHRF1 for deubiquitination and affects UHRF1 protein stability in vivo. Furthermore, Dnmt1, UHRF1 and USP7 co-localized on silenced, methylated genes in vivo. Strikingly, when analyzing the impact of UHRF1 and USP7 on Dnmt1-dependent DNA methylation, we found that USP7 stimulated both the maintenance and de novo DNA methylation activity of Dnmt1 in vitro. Therefore, we propose a dual role of USP7, regulating the protein turnover of UHRF1 and stimulating the enzymatic activity of Dnmt1 in vitro and in vivo.
Using public transportation as a DTN backbone

This thesis focuses on the mobility properties of route-and schedule-based networks, such as public transportation networks. We are interested in the behaviour of nodes in such networks and the feasibility of using them as a DTN backbone. We model the Zurich and Amsterdam tram networks and analyse the distribution of the inter-contact times. Our ﬁrst contribution is that we ﬁnd these inter-contact times to be exponentially distributed. We then adapt simple analytical models based on random mixing and exponential inter-contact times for the expected delivery delay in delay tolerant networks to our network and compare them to experimental results. The analytical model proves to be an accurate predictor of real performance over a variety of densities. Finally we perform a feasibility study to determine the potential of enabling stops to relay messages and analyse the congestion for epidemic routing.
Laplace-Pressure Actuation of Liquid Metal Devices For Reconfigurable Electromagnetics

Present day electronics are now taking on small form factors, unexpected uses, adaptability, and other features that only a decade ago were unimaginable even for most engineers. These electronic devices, such as tablets, smart phones, wearable sensors, and others, have further had a profound impact on how society interacts, works, maintains health, etc. To optimize electronics a growing trend has been to both minimize the physical space taken up by the individual electronic components as well as to maximize the number of functionalities in a single electronic device, forming a compact and efficient package. To accomplish this challenge in one step, many groups have used a design that has reconfigurable electromagnetic properties, maximizing the functionality density of the device. This would allow the replacement of multiple individual components into an integrated system that would achieve a similar result as the separate individual devices while taking up less space. For example, could a device have a reconfigurable antenna, allowing it optimal communication in various settings and across multiple communication bands, thus increasing functionality, range, and even reducing total device size. Thus far a majority of such reconfigurable devices involve connecting/disconnecting various physically static layouts to achieve a summation of individual components that give rise to multiple effects. However, this is not an ideal situation due to the fact that the individual components whether connected or not are taking up real-estate as well as electrical interference with adjacent connected components. This dissertation focuses on the reconfigurability of the metallic component of the electronic device, specifically microwave devices. This component used throughout this dissertation is that of an eutectic liquid metal alloy. The liquid metal allows the utilization of both the inherent compact form (spherical shape) of a liquid in the lowest energy state and the fact that it is resilient and shapeable to allow for reconfigurability. In this dissertation, first background information is given on the existing technology for reconfigurable microwave
24 0 v 2 10 F eb 2 00 3 de Sitter Vacua in String Theory

We outline the construction of metastable de Sitter vacua of type IIB string theory. Our starting point is highly warped IIB compactifications with nontrivial NS and RR three-form fluxes. By incorporating known corrections to the superpotential from Euclidean D-brane instantons or gaugino condensation, one can make models with all moduli fixed, yielding a supersymmetric AdS vacuum. Inclusion of a small number of D3 branes in the resulting warped geometry allows one to uplift the AdS minimum and make it a metastable de Sitter ground state. The lifetime of our metastable de Sitter vacua is much greater than the cosmological timescale of 10 years. We also prove, under certain conditions, that the lifetime of dS space in string theory will always be shorter than the recurrence time.
Diversity of Biofilm-Forming Bacteria in Chinnamuttom Harbor of Southeast India

Biofilms are species rich, partially due to highly effective powers of diffusion of the microorganisms and have wide tolerance to marine environmental conditions. Characteristically, the first organisms to respond to and convalesce from stress. The present study aims to isolate and identify the biofilm forming bacterial species, collected from surface water and substratum of the ship hull for four seasons at Chinnamuttom fishing harbor, Southeast coast of India, during June 2015 to May 2016. Among the mean concentration of bacterial isolates of both water and substratum of the station, maximum in monsoon and minimum in summer seasons. Totally 16 isolates were obtained, based on the adherence property, 8 isolates from surface water and 8 isolates from substratum of the ship hull.

The isolates of Bacillus sp. , Flavobacterium sp. , Pseudomonas sp. , Aeromonas sp. , Micrococcus sp. , Vibrio sp. , Salmonella sp. , Staphylococcus sp. , Shegella sp. , Klebsiella sp. , Corynebacterium sp. , Enterobacter sp. , Chromohalobacter sp. , Bacillus sp. , Escherichia coli and Bacilus sp. were reported in all the seasons at study area. The major diverse bacterial isolates were further characterized through morphological and molecular identification. Based on 16S rRNA gene sequences. Biofilm bacterial isolates were confirmed as Bacillus sp. , and Pseudomonas sp.
Callus Induction and Determination of Iridoid Glycosides from Barleria prionitis

Callus cultures of Barleria prionitis Linn were established from leaf explants in Murashige and Skoog (MS) medium supplemented with various combinations of -Naphthalene acetic acid (NAA) and 6-benzylaminopurine (BA). The explants developed compact greenish calluses in the presence of NAA (1.0 mg/L) and BA (0.5 mg/L). The growth of calluses was measured over 60 days. Maximum dry biomass, 0.143 g, was obtained at 50 days. Calluses were extracted with methanol to examine the presence of the iridoid glycosides having biological activity in intact plants. The methanol extracts were further separated by solvent-solvent extraction to give dichloromethane and n-butanol solubles or n-hexane, chloroform and n-butanol solubles. Each soluble was analyzed by TLC (thin layer chromatography) and HPLC (high pressure liquid chromatography). The n-hexane and chloroform solubles or dichloromethane solubles did not contain glycosides, but the n-butanol solubles showed the existence of glycosides on the TLC plate sprayed with p-anisaldehyde-sulfuric acid reagent. However, the n-butanol solubles in the methanol extracts of callus contained neither of the iridoid glycosides (8-O-Acetyl shanzhiside methyl ester (barlerin) and shanshiside methyl ester) present in intact plants. However, a glucoside was detected in the n-butanol solubles from the methanol extracts of callus by TLC. This study also attempted to determine the anticancer activity of methanol extracts from B. prionitis L. However, the methanol extracts were found to be inactive.
Document images forgery localization using a two‐stream network

Document images often contain essential and sensitive information. With image editing software, one can easily manipulate the semantic meaning of the document image by copy‐move, splicing, and removal, which causes many security issues. Hence, the document image forgery detection and localization are of great significance. In this paper, a novel two‐stream network is proposed to detect and locate the forgery regions of document images. One stream captures forgery traces from the spatial information, including unnatural boundaries, contrast/brightness inconsistencies, and blurring. The other stream eliminates the image semantics by six residual filters, then capture the anomalous features between neighboring pixels introduced by upsampling, downsamping, and inpainting. Finally, the discriminant network is introduced to deeply fuse features from the two streams, and discriminates whether each image patch is forged or not using global average pooling and fully connected layer. Extensive experimental results on our constructed document image data set and the Security AI Challenger Program data set demonstrate the proposed two‐stream network outperforms state‐of‐the‐art methods. This proposed two‐stream network is also better than each single stream, and is robust to some common forgery postprocessing operations.
Evolution of Dam Lakes in the Kayanga/Geba Basin: Contribution of Remote Sensing and GIS

The Confluent and Niandouba dams were built in 1984 and 1997 respectively to better control water resources, increase agricultural production and promote local development. This article studies their evolution on the Kayanga/Geba River, a transboundary river between Guinea, Senegal and Guinea-Bissau, from its impoundment to the present day. The topographic characteristics analysed through the DTMs (Digital Terrain Models) show a flat shape for the Confluent Dam Lake and long plateaus for the Niandouba Dam Lake. The cross-sections present a variety of morphologies ranging from wide U-shaped valleys with sinuous bottoms to deep V-shaped valleys. The homogenisation and reconstruction of missing values were carried out using the regional vector method. The application of Pettitt’s statistical test on annual rainfall (1932-2019) indicates breaks of stationarity in 1967 or 1969. The post-breakage deficits range from 11.4% to 19.4%. The segmentation method corroborates the results of the Pettitt test. The variations of the surface area of the Confluent and Niandouba water bodies are linked to rainfall, evaporation and withdrawals for different uses. Their monitoring would allow for better management of available water resources but also for good planning of off-season crops.
Motion Amidst Polygonal Obstacles *

Let ~'t . 3% be m simple Jordan curves in the plane, and let K 1 . K m be their respective interior regions. It is shown that if each pair of curves 7i, ~'j, i ~ j , intersect one another in at most two points, then the boundary of K =1. )~"= 1Ki contains at most max(2, 6m 1 2 ) intersection points of the curves y,, and this bound cannot be improved. As a corollary, we obtain a similar upper bound for the number of points of local nonconvexity in the union of rn Minkowski sums of planar convex sets. Following a basic approach suggested by Lozano Perez and Wesley, this can be applied to planning a collision-free translational motion of a convex polygon B amidst several (convex) polygonal obstacles A 1 . Am. Assuming that the number of corners of B is fixed, the algorithm presented here runs in time O(n log2n), where n is the total number of comers of the Ai's.
Physical-Chemical Characteristic and Trophic Status of Some Small Lakes in Ciliwung Watershed, West Java Indonesia

Small lakes are important freshwater resources to support the quality of human life. However, small lakes in the watershed are becoming threatened ecosystems because of increasing land-use changes and anthropogenic activity. The study aimed to determine characteristic physical-chemical parameters and trophic status some small lake in Ciliwung Watershed to support the sustainable management of small lakes in the Ciliwung watershed in preventing eutrophication effects. The data was collected in April and June 2021. Measurement and analysis of water quality parameters were conducted by insitu and Laboratory. Some parameters were not in accordance with the Government Regulation number 22/2021 for class II water quality criteria (WQC), including TSS (>50 mg.L-1). , TP (>0.03 mg.L-1), COD (>25 mg.L-1) and DO (<3 mg.L-1), especially for Lake Sunter and Lake Cincin.There are two groups of lakes based on water quality and trophic status. Lake Telaga Warna Lake Cikaret, and Lake Cilodong were classified as eutrophic while lake Sunter and Lake Cincin were classified as hypereutrophic lake Lake Telaga Warna, Lake Cikaret, and Lake Cilodong, located at the upper and middle watershed, are eutrophic, characterized by deeper bottom and higher Secchi depth. At the lower watershed, Lake Sunter and Lake Cincin are hypereutrophic characterized by higher nutrients (TN and TP), COD, temperature, conductivity, salinity, and TDS. The downstream area was a densely populated area that contributed high pollution from upstream and middle of Ciliwung watershed.
