The objective of this study is to identify how the policies of financing influence the performance of Microfinance institutions (MFI). In this study, we used the MIX Market database in order to bring out information relating to the variables of financing and performance structures. The data used was obtained from eight Institutions of Microfinance in Cameroon, and were collected over a period of eight years going from 2006 to 2013. An analysis of the regressions based on a sample of 64 observations collected on 8 Cameroonian MFIs for 8 years, on the one hand, shows that the level of indebtedness also influences financial and social performance negatively

Purpose This paper aims to investigate the relationship between microfinance institutions (MFIs) governance and performance. Design/methodology/approach Using a sample of 215 MFIs from six South Asian countries over the period from 2005 to 2009, the authors examine the effect of chief executive officer (CEO) duality, board size, female CEO, urban market coverage, bank regulation and lending type on financial and social performance of MFIs. Findings The findings provide evidence that, on the one hand, empowered CEO, large board size and individual lending improve the MFI financial performance and, on another hand, bank regulation and serving in the urban market have a significant association with MFIs’ social performance. In an additional analysis, the authors also test this relationship before, during and after the financial crisis of 2007. During crisis period, MFIs’ individual lending reduces the operational cost and bank regulation increases the average loan size in South Asian MFIs. Originality/value Those studies that are presented in the literature review conclude their result on the bases of global, European, East African and specific to some countries sample. There is no study presented in the whole literature on South Asian sample, in which all countries really face the problem of poverty.

Supply Side Factors

We study how a multisided platform’s decision to certify a subset of its complementors affects those complementors and ultimately the platform itself. Kiva, a microfinance platform, introduced a social performance badging program in December 2011. The badging program appears to have been beneficial to Kiva—it led to more borrowers, lenders, total funding, and amount of funding per lender. To better understand the mechanisms behind this performance increase, we study how the badging program changed the bundle of products offered by Kiva’s complementors. We find that Kiva’s certification leads badged microfinance institutions to reorient their loan portfolio composition to align with the certification and that the extent of portfolio reorientation varies across microfinance institutions, depending on underlying demand- and supply-side factors. We further show that certified microfinance institutions that do align their loan portfolios enjoy stronger demand-side benefits than do certified microfinance institutions that do not align their loan portfolios. We therefore demonstrate that platforms can influence the product offerings and performance of their complementors—and, subsequently, the performance of the ecosystem overall—through careful enactment of governance strategies, a process we call “market orchestration.”

Critical Literature

This critical literature review begins by giving a short introduction to the microfinance industry. Microfinance institutions (MFIs) are explained and an account is given of their dual performance goals of financial performance (‘financial sustainability’) and social performance (‘outreach’). While MFIs’ social performance is directly aimed at poverty reduction, it is noteworthy that often they fail to address poverty (i.e., they fail to deliver outreach). The aim of the paper is to answer the following research question: Why have microfinance institutions (MFIs) failed to address poverty? In order to establish the reason, the first step is to look at how the MFIs are managed and controlled, i.e. to examine MFIs’ corporate governance literature. This critical literature review was conducted using systematic on-line searches in the databases Scopus and Web of Knowledge; the main key words used were microfinance, gender, corporate governance and performance. The unconvincing nature of the findings of a review of the corporate governance literature suggests that another factor should be taken into consideration: that of gender; after all, MFIs are mainly used by women. The findings from reviewing the microfinance literature suggests that microfinance gender literature may explain why MFIs have not adequately addressed poverty, but this literature consists of a few studies only and further studies are needed. The literature on gender in general is more substantial, however. Some account of it will be given in this literature review. The findings of this literature review should benefit policymakers on the one hand, who are in a position to advance gender equality, while on the other hand it should be of use to academics, who can research MFIs in relation to gender; further studies of gender in MFIs are encouraged.

The current study contributes to the existing literature on the relationship between corporate governance (CG) and social performance (SP) of microfinance institutions (MFIs) by introducing CG index for the first time purely in the perspective of Asian MFIs. Moreover, this research also investigates the existence of endogeneity by checking the reverse causality between CG and SP as many previous studies highlighted the endogenous nature of many governance and performance variables. Using a panel of 173 MFIs in 18 Asian countries for the period of 5 years, a comprehensive CG index (CGI) based on seven internal governance mechanism variables is constructed as an indicator of the overall CG mechanism of MFIs. By employing generalized least squares (GLS) model, our results indicate insignificant impact of CG on many SP variables which are attributed to the endogenous nature of this relationship as the significance of results improved by studying relationship in reverse direction by employing ordered logit model. Our results indicate that SP is an important determinant of CG mechanism of MFIs even after controlling for MFI-related characteristics.

The Paris avant-garde milieu from which both Cirque Calder/Calder's Circus and Painlevé’s early films emerged was a cultural intersection of art and the twentieth-century life sciences. In turning to the style of current scientific journals, the Paris surrealists can be understood as engaging the (life) sciences not simply as a provider of normative categories of materiality to be dismissed, but as a companion in apprehending the “reality” of a world beneath the surface just as real as the one visible to the naked eye. I will focus in this essay on two modernist practices in new media in the context of the history of the life sciences: Jean Painlevé’s (1902–1989) science films and Alexander Calder's (1898–1976) work in three-dimensional moving art and performance—the Circus. In analyzing Painlevé’s work, I discuss it as exemplary of a moment when life sciences and avant-garde technical methods and philosophies created each other rather than being classified as separate categories of epistemological work. In moving from Painlevé’s films to Alexander Calder's Circus, Painlevé’s cinematography remains at the forefront; I use his film of one of Calder's performances of the Circus, a collaboration the men had taken two decades to complete. Painlevé’s depiction allows us to see the elements of Calder's work that mark it as akin to Painlevé’s own interest in a modern experimental organicism as central to the so-called machine-age. Calder's work can be understood as similarly developing an avant-garde practice along the line between the bestiary of the natural historian and the bestiary of the modern life scientist.

This study discusses convolutional neural networks (CNNs) for vibration signals analysis, including applications in machining surface roughness estimation, bearing faults diagnosis, and tool wear detection. The one-dimensional CNNs (1DCNN) and two-dimensional CNNs (2DCNN) are applied for regression and classification applications using different types of inputs, e.g., raw signals, and time-frequency spectra images by short time Fourier transform. In the application of regression and the estimation of machining surface roughness, the 1DCNN is utilized and the corresponding CNN structure (hyper parameters) optimization is proposed by using uniform experimental design (UED), neural network, multiple regression, and particle swarm optimization. It demonstrates the effectiveness of the proposed approach to obtain a structure with better performance. In applications of classification, bearing faults and tool wear classification are carried out by vibration signals analysis and CNN. Finally, the experimental results are shown to demonstrate the effectiveness and performance of our approach.

Computing the sparse fast Fourier transform (sFFT) has emerged as a critical topic for a long time because of its high efficiency and wide practicability. More than twenty different sFFT algorithms compute discrete Fourier transform (DFT) by their unique methods so far. In order to use them properly, the urgent topic of great concern is how to analyze and evaluate the performance of these algorithms in theory and practice. This paper mainly discusses the technology and performance of sFFT algorithms using the aliasing filter. In the first part, the paper introduces the three frameworks: the one-shot framework based on the compressed sensing (CS) solver, the peeling framework based on the bipartite graph and the iterative framework based on the binary tree search. Then, we obtain the conclusion of the performance of six corresponding algorithms: the sFFT-DT1.0, sFFT-DT2.0, sFFT-DT3.0, FFAST, R-FFAST, and DSFFT algorithms in theory. In the second part, we make two categories of experiments for computing the signals of different SNRs, different lengths, and different sparsities by a standard testing platform and record the run time, the percentage of the signal sampled, and the L0, L1, and L2 errors both in the exactly sparse case and the general sparse case. The results of these performance analyses are our guide to optimize these algorithms and use them selectively.

AbstractThe COVID-19 pandemic has given rise to the massive development and use of health indicators. Drawing on the history of international public health and of the management of infectious disease, this paper attempts to show that the normative power acquired by metrics during the pandemic can be understood in light of two rationales: epidemiological surveillance and performance assessment. On the one hand, indicators are established to evaluate and rank countries’ responses to the outbreak; on the other, the evolution of indicators has a direct influence on the content of public health policies. Although quantitative data are an absolute necessity for coping with such disasters, it is critical to bear in mind the inherent partiality and precarity of the information provided by health indicators. Given the growing importance of normative quantitative devices during the pandemic, and assuming that their influence is unlikely to decrease in the future, they call for close scrutiny.
