La semence et la biotine : découverte d'une protéine à biotine chez Pisum sativum L., marqueur moléculaire de la maturation des semences et des phases précoces de la germination

L'etat de vie ralentie caracterise la semence orthodoxe des spermaphytes. Cet etat, induit au cours de la maturation, est leve pendant la germination. La biotine est une molecule necessaire a toute forme de vie. Le mecanisme moleculaire determinant l'etat de vie ralentie est encore inconnu. La biotine peut-elle intervenir dans ce phenomene biologique ? cette these tend a le demontrer. La biotine est decrite comme etant le cofacteur d'enzymes catalysant des reactions de carboxylations. Or, dans les cellules de tous les organes de la plante et a tout moment de son cycle, la biotine libre est en exces par rapport a la biotine liee aux carboxylases. La semence mature est l'unique exception. Deuxieme caracteristique de la semence: elle contient une proteine biotinylee specifique, liant la biotine de maniere covalente. Sa masse moleculaire apparente est de 65 kda, d'ou sa denomination de sbp65 pour seed biotinyl protein (proteine de semence). Depourvue d'activite enzymatique a biotine, sa cinetique d'accumulation au cours de la maturation est concomitante avec l'epuisement de la biotine libre des cellules embryonnaires. Elle est localisee dans le cytoplasme, lieu de synthese de la biotine (baldet, 1993). Tout se passe comme si la sequestration de la biotine par sbp65 de maniere physiologique en fin de maturation chez le pois reproduisait le phenotype du mutant bio1 de l'arabette (shellammer et meinke, 1990). Cette mutation letale correspond a une deficience de synthese de biotine qui entraine une interruption precoce du developpement embryonnaire. Ceci suggere que la regulation du niveau de biotine libre, i. E. Celle disponible pour les carboxylases a biotine indispensables a un metabolisme normal, est un mecanisme de modulation de l'activite metabolique globale. D'ou les observations suivantes: sbp65 est degradee aussitot que le metabolisme reprend au cours de la germination et son gene n'est jamais exprime en dehors de l'embryon en fin de maturation. Sbp65 a son equivalent dans les especes agronomique. Au niveau moleculaire, elle presente deux caracteristiques: elle est tres hydrophile et possede plusieurs motifs repetes, ce qui l'apparente au groupe des proteines lea (late embryogenesis abundant i. E. Abondante en fin d'embryogenese). D'autre part, la structure primaire de sa region biotinylee est radicalement differente de celle de toutes les autres proteines a biotine d'ou son absence d'activite enzymatique

Radulidium subulatum, new taxon for mycobiota of Iran

Alfalfa (Medicago sativa L.), a member of Fabaceae family, is a perennial or permanent plant with upright and very deep root that penetrates up to three meters into the soil, and therefore is the source of vitamins and minerals that takes from the soil. This plant is very important in terms of chemical and pharmaceutical compositions. In order to identify the fungi accompaning leaf spot symptoms of the alfalfa, leaves with leaf spot symptoms were collected from Sheikh Ali Khan region of the Chaharmahal and Bakhtiari province (Iran) during July 2018. The samples were transferred to laboratory and then small pieces (5 × 5 mm) were cut from the margin of leaf spots. Resulting leaf pieces were surface disinfested with 1% sodium hypochlorite for 30 sec. and then washed three times with sterilized water and were put on sterilized filter paper to remove excess water. Disinfested leaf pieces were transferred on 2% water agar medium. Isolates were purified by hyphal tip method and then were transferred to Petri dishes containing PDA culture medium and the grown fungal colonies were kept for seven days at 25 °C in continuous dark condition. Of the obtained fungal isolates, one isolate was identified as Radulidium subulatum (de Hoog) Arzanlou, W. Gams & Crous based on morphological features. According to the available literatures, this is the first report of Radulidium subulatum for mycobiota of Iran. The diameter of the fungus colony on malt extract agar (MEA) after 14 days of growth at 24 °C in continuous dark condition were 50 mm, and the colony of the fungus was pale gray in color (Fig. 1a). Conidiophores were pale brown, smooth, tapering toward the apex and have short conspicuous denticles at the tip, where the conidia were attached to the conidiophores. Denticles were densely crowded, prominent, blunt at the end and pale brown in color. The dimension of the conidiophores were 14–28(21) × 1.5–3(2.25) µm (Fig. 1 b–d). Conidia were solitary, single-celled, smooth, ellipsoid, pale brown and 4–7(5.5) × 1.5–2(1.75) µm in diameter. Conidia had short hilum with about one micrometer in length.
Assessing the Operationalization of Cultural Theory through Surveys Investigating the Social Aspects of Climate Change Policy Making

Cultural theory (CT) provides a framework for understanding how social dimensions shape cultural bias and social relations of individuals, including values, view of the natural world, policy preferences, and risk perceptions. The five resulting cultural solidarities are each associated with a “myth of nature”—a concept of nature that aligns with the worldview of each solidarity. When applied to the problem of climate protection policy making, the relationships and beliefs outlined by CT can shed light on how members of the different cultural solidarities perceive their relationship to climate change and associated risk. This can be used to deduce what climate change management policies may be preferred or opposed by each group. The aim of this paper is to provide a review of how CT has been used in surveys of the social aspects of climate change policy making, to assess the construct validity of these studies, and to identify ways for climate change protection policies to leverage the views of each of the cultural solidarities to develop clumsy solutions: policies that incorporate strengths from each of the cultural solidarities’ perspectives. Surveys that include measures of at least fatalism, hierarchism, individualism, and egalitarianism and their associated myths of nature as well as measures of climate change risk perceptions and policy preferences have the highest translation and predictive validity. These studies will be useful in helping environmental managers find clumsy solutions and develop resilient policy according to C.S. Holling’s adaptive cycle.
Composing Professional Human Resource: The Necessity of Excellent Internship Mentoring System

University is primarily being a wide place or facility to produce capable, intelligent and professional workforce. Students are equipped with various kinds of knowledge theoretically as well as trained through the internship process. However, the findings on graduates who don’t reflect some aspects of professionalism, less competent in each of their fields or even their soft skills should be classified as urgent issues at any rate. Driven by these contrary sides, we highlighted that the less maintained students’ internship period might be a variable for the problems. We started by collecting previous studies on the dissatisfactions from employers about trainees/interns from universities, analyzed the solutions, and triangulated the solutions we proposed by exploring internship masterplan at a university in Indonesia. From all of these steps, we found that appropriate, intensive mentoring ways in the students’ internship period are the main points to create the skills that meet any employers’ demands. We believe that the results of this study will be very useful for those who need answers to the best ways to improve the quality and capabilities of higher education graduates.

Enabling Fine-Grained Shopping Behavior Information Acquisition With Dual RFID Tags

Shopping behavior information acquisition and mining are of great importance for marketing and merchandizing strategies developing. With a single tag on each commodity, the previous pattern-based works only can be considered as behavior recognition solutions with behavior streams as output for each tag. In this article, we introduce a completely new mode of dual tags and propose a fine-grained shopping behavior acquisition solution called as fine-grained shopping behavior information acquisition (FGSA). FGSA enables shopping behaviors recognition by taking advantage of the phase calibrated Doppler shift of dual tags and extracts fine-grained behavior information for each behavior from the fusion Doppler spectrums with only one antenna. We implement a prototype of FGSA with COTS radio-frequency identification (RFID) devices and conduct extensive experiments to evaluate its performance. The experimental results demonstrate that FGSA achieves excellent performance in terms of both behavior recognition and information extraction.
Nonlinear Spatial Filtering for Multichannel Speech Enhancement in Inhomogeneous Noise Fields

A common processing pipeline for multichannel speech enhancement is to combine a linear spatial filter with a single-channel postfilter. In fact, it can be shown that such a combination is optimal in the minimum mean square error (MMSE) sense if the noise follows a multivariate Gaussian distribution. However, for non-Gaussian noise, this serial concatenation is generally suboptimal and may thus also lead to suboptimal results. For instance, in our previous work, we showed that a joint spatial-spectral nonlinear estimator achieves a performance gain of 2.6 dB segmental signal-to-noise ratio (SNR) improvement for heavy-tailed large-kurtosis multivariate noise compared to the traditional combination of a linear spatial beamformer and a postfilter.In this paper, we show that a joint spatial-spectral nonlinear filter is not only advantageous for noise distributions that are significantly more heavy-tailed than a Gaussian but also for distributions that model inhomogeneous noise fields while having rather low kurtosis. In experiments with artificially created noise we measure a gain of 1 dB for inhomogenous noise with low kurtosis and up to 2 dB for inhomogeneous noise fields with moderate kurtosis.
Building Financial Resilience Through Financial and Digital Literacy in South Asia and Sub-Saharan Africa

Abstract Globally, 1.7 billion adults still lack access to formal financial services, with a large percentage living in South Asia and Sub-Saharan Africa. Current financial inclusion strategies seek to enhance these vulnerable populations' access to financial services with the aim of building more inclusive and financially resilient societies. With the Fintech movement and over 67% of the world's population having a mobile phone, digital financial literacy is gaining momentum. Nevertheless, negligible research has measured its impacts on financial behavior. This study uses data from the InterMedia Financial Inclusion Insights (FII) surveys for seven South Asian and Sub-Saharan African countries to investigate the relationship between multidimensional measures of financial and digital literacy and resilience-building financial behaviors, including saving, borrowing, and risk management. The findings consistently show that both financial and digital literacy are key factors to building inclusiveness and financial resilience. Heterogeneities are identified across regions, as well as for poor, rural, and female households. A robustness check is also included to address potential endogeneity. The results emphasize the need to redefine traditional financial literacy to include digital literacy, with important implications for countries considering both as a dual approach to improving households' long-run financial resilience.
Barriers to Interpersonal Communication as a Tool for Improving the Uptake of Voluntary Medical Male Circumcision in Siaya County, Kenya

Despite its acknowledged importance in health management, particularly when dealing with such sensitive issues that transcend the boundaries of health as sexuality, stigma and discrimination, there is little research on the efficacy of interpersonal communication (IPC) in health programmes in Kenya. Consequently, little is documented on barriers to IPC in the implementation of health interventions. We examined specific potential barriers to IPC as an integral device in the implementation of the voluntary medical male circumcision (VMMC) programme in Siaya, Kenya. We used a mixed-methods sequential cross-sectional research design, and the multi-stage sampling technique – combining purposive and chain referral sampling procedures to arrive at the desired samples. Two questionnaires were administered on 370 male residents of Bondo and Rarieda in Siaya; and on 35 implementers of the programme in the two sub-counties. Further, we interviewed five managers from the implementing agencies. We used descriptive and inferential statistics to analyse quantitative data, and presented the findings through text and tables, while qualitative data were analysed through the description, analysis and interpretation process. The findings show time constraints as a significant barrier chiefly from the viewpoint of the operational staff, who admitted lacking time for meaningful interactions with their clients to fully explain issues raised for desired mutual understanding. Culture, in its various forms, has a significant negative cross-cutting bearing on provider-client interactions, while provider-client language difference, coupled with service providers’ attitude and jargons had a potential negative effect on the VMMC programme’s final outcome, at least from the clients’ perspective. We recommend full integration of IPC in healthcare management. Communication training should be accorded its due prominence, both in terms of scope and depth, in all heath training institutions. We further vouch for service provider cultural competence to enhance understanding. IPC can play a crucial role in healthcare management in Kenya due to its ability to facilitate important provider-client transaction, particularly in the largely oral rural resource-deprived populations, which lack adequate access to mass communication media. This study has discussed a raft of potential barriers to IPC, and provides significant insights to planners and managers of management of health programmes and interventions.

A Gradient-Aware Line Sampling Algorithm for LiDAR Scanners

Due to a slow acquisition, the spatial resolution of a depth-acquisition device, such as a Light Detection and Ranging (LiDAR) sensor, is limited, which strictly requires scanning a field of view (FOV) in a particular order. To accurately reconstruct a depth image from limited spatial samples, two-stage sampling has been widely used. However, from the perspective of a LiDAR, two-stage sampling requires scanning the FOV two times to build a depth map, and eventually becomes counterintuitive in practice. To address this problem, this study presents a LiDAR framework and a gradient-aware line-based sampling algorithm. Different from previous works, the proposed scanning algorithm allows a LiDAR to scan the FOV from top to bottom while simultaneously seeking sampling points along object boundary. By utilizing the information of the previous line during scanning, the proposed method maintains the conventional scanning order in a LiDAR, while efficiently predicting the sampling locations of the current line. The experimental results demonstrate that the proposed sampling outperforms grid sampling by at most 9.79 dB on the synthetic datasets. Consequently, the proposed sampling achieves reconstructed quality similar to that of optimal sampling in the previous design, while substantially reducing the computation time and memory requirements. The experimental results with the laser range data and the real data captured by the LiDAR system demonstrate that the proposed method can reduce the averaged mean-absolute-error (MAE) by 34.91%, 47.23%, 54.88%, and 57.99% for the sampling ratios of 20%, 30%, 40%, and 50%, respectively, compared to the conventional LiDAR sampling.

Impact of Overconfident CEO On Dividend Policy: Evidence in Enterprises Listed On Hose of Vietnam

A high dividend payout policy will make it attractive for shareholders when their investments are profitable, which is reflected in the dividend payout. At the same time, the behavior of dividend payout depends on the decisions of the CEO. CEOs with different confidence will influence different dividend policies. Therefore, the author assesses the impact of Overconfident CEO on dividend policy in enterprises of Vietnam. An analysis of 372 enterprises listed on the HOSE by the panel data model showed that Overconfident CEO has a negative impact on dividend payout. At the same time, research also shows that leverage has a negative impact on dividend payout; firm size has a positive impact on dividend payout. From the results of this study, the author also made recommendations to support investors as well as shareholders in the enterprises to make decisions appropriate to their investment goals.
Behavioral Profiles of Adolescent Alcohol-Preferring/Non-preferring (P/NP) and High/Low Alcohol-Drinking (HAD/LAD) Rats Are Dependent on Line but Not Sex

Initial contact with alcohol generally occurs during adolescence, and high consumption during this period is associated with increased risk for later alcohol (AUDs) and/or substance use disorders (SUDs). Rodents selectively bred for high or low alcohol consumption are used to identify behavioral characteristics associated with a propensity for high or low voluntary alcohol intake. The multivariate concentric square field™ (MCSF) is a behavioral test developed to study rodents in a semi-naturalistic setting. Testing in the MCSF creates a comprehensive behavioral profile in a single trial. The current aim was to examine the behavioral profiles of adolescent, bidirectionally selectively bred male and female high alcohol-consuming (P and HAD1/2) and low alcohol-consuming (NP and LAD1/2) rat lines, and outbred Wistar rats. Alcohol-naïve rats were tested once in the MCSF at an age between postnatal days 30 and 35. No common behavioral profile was found for either high or low alcohol-consuming rat lines, and the effect of sex was small. The P/NP and HAD2/LAD2 lines showed within pair-dependent differences, while the HAD1/LAD1 lines were highly similar. The P rats displayed high activity and risk-associated behaviors, whereas HAD2 rats displayed low activity, high shelter-seeking behavior, and open area avoidance. The results from P rats parallel clinical findings that denser family history and risk-taking behavior are strong predictors of future AUDs, often with early onset. Contrarily, the HAD2 behavioral profile was similar to individuals experiencing negative emotionality, which also is associated with a vulnerability to develop, often with a later onset, AUDs and/or SUDs.
Digitalization of Local Owner-Operated Retail Outlets: Between Customer Demand, Competitive Challenge and Business Persistence

The digitalization of the retail industry is a disruptive innovation process that threatens the very existence of Local Owner Operated Retail Outlets (LOOROs). Despite the manifold digital options to regain competitive power, LOOROs struggle in their digital transformation and persist often in their traditional business behavior. As their customers get more and more used to buying via digital channels, they more and more expect the provision of digital services. This paper and the presented study aim to understand why the LOOROs are so hesitant. Our results show that the owners of LOOROs are often decoupled from their near and far business environment. This leads to a wrong selfassessment and implies the risk that the services provided do neither match the competitive environment nor customer expectations.
The Impact of Demonetization on the Short-Term and Long-Term Returns of India’s Leading Real Estate Index

This article examines the short-term and long-term impact of demonetization on the daily and monthly returns of the Standard & Poor Bombay Stock Exchange (S&P BSE) Realty Index, India’s leading real estate index. Demonetization is supposed to result in a liquidity crunch in the market and have a negative impact on real estate activity and real estate stock market returns. The results suggest that the S&P BSE Realty Index had statistically lower returns immediately after the announcement of demonetization. However, the impact dissipated within 1 month. Furthermore, when we compared the monthly returns from the S&P BSE Realty Index with similar returns on the BSE Sensex index, we found no long-term impact of demonetization on the Realty Index. Our results suggest that markets reacted to demonetization as an opportunity to move to a cashless system that will reform the real estate sector and attract global investors, including hedge funds, to invest in the real estate market of India because of growing demand for residential and commercial real estate. TOPICS: Real estate, emerging markets, wealth management, currency Key Findings • Markets reacted to demonetization as an opportunity to move to a cashless system that will reform the real estate sector and attract global investors including hedge funds to invest in the real estate market of India because of growing demand for residential and commercial real estate. • On the day of the event and the day following the event, the S&P BSE Realty Index returns were negative. These returns were short term only and dissipated a few days after the announcement. • Short-term after effects of demonetization are consistent with previous studies that analyzed the effect of demonetization because of introduction of a single currency, the euro.
