The Association of Parental Interest in Entrepreneurship to the Entrepreneurial Interest of Spanish Youth

As entrepreneurial interest is believed to represent a causal factor increasing entrepreneurship, research has begun to explore how family systems affect youth entrepreneurial interests. In the present study, we attempt to identify different types of family influence on the entrepreneurial interests of young people. A questionnaire was used to obtain data from 1,633 Spanish youths, who were 15 to 18 years old, and another questionnaire was used to obtain data from 839 parents. Principal Component Analysis identified unique family types and revealed that they have differential associations to entrepreneurial interest among youths. These findings reaffirm the influence of family on the entrepreneurial ecosystem and the promotion of an entrepreneurial family cuture. This study further suggests that early attention should focus on the detection of entrepreneurial interest among youths so that actions can be implemented in the families of lowinterest youths to incentivize an entrepreneurial family culture.
Effect of Different Propagation Methods on three Lowland Bamboo Species, at Bako Agro-ecology, West Shoa, Oromia, Ethiopia

Bamboo is one of the most important, fast-growing and drought-resistant species. These behaviors make the species more acceptable in making a good environment in addition to soil and water conservation and rehabilitation of degraded lands. The study was conducted on the effect of different propagation techniques using three lowland bamboo species to find out the best-preformed propagation ways. The experiment was conducted in Bako Agriculture Research Center from 2015 to 2017. A factorial arrangement of randomized complete block design (RCBD) with three replications was used. The experimental materials were; rhizome, branches, lower and middle culms cutting parts and three species (Oxythenantera abyssinica, Dendrocalamus hamlitonii, and Dendrocalamus memebranceous) was used. A total of 144 planting materials were planted in each experimental plot using four planting material. There was a significant difference between the species and propagation methods. The newly emerging shoots revealed a significant difference under Dendrocalamus hamlitonii (1.30±0.8) among other species. Under all species and treatments, Dendrocalamus hamlitonii showed a better performance than others regarding survival rate, root collar diameter, culm height, and internodes length. Besides this, a branch treatment under all species showed a poor performance. Therefore, this study confirmed that following rhizome part using lower and middle culm part recommended as a promising propagation technique for lowland bamboo species. Further investigation on the biological factors that hamper the initiations of new shoots and survival in using branch cutting methods is also recommended.
Is there any Link Between Vitamin D and Recurrence of Atrial Fibrillation after Cardioversion?

Introduction Atrial fibrillation (AF) is the most common chronic arrhythmia in the elderly population. In symptomatic patients, restoration and maintenance of sinus rhythm improve quality of life. Unfortunately, AF recurrence still occurs in a considerable number of patients after cardioversion (CV). In this study, we aimed to evaluate the association between vitamin D (VitD) and AF recurrence after electrical or medical CV. Method A total of 51 patients who underwent CV for symptomatic AF were included in the study. AF recurrence was defined as an AF pattern in 12-lead electrocardiography (ECG) recording after CV within 6 months or ECG Holter recording of AF lasting more than 30 seconds at 6-month follow-up. Results Mean vitD level was 21.4 ng/ml in our study population. VitD level was lower in the AF recurrence group than in the non-recurrence group (18 ng/ml vs. 26.3 ng/ml, respectively; P=0.001). Additionally, left atrial diameter was larger in the AF recurrence group compared to the non-recurrence group (4.4 vs. 4.1, P=0.025). Patients with AF recurrence were older than patients without AF recurrence, and, although the prevalence of hypertension is higher in the AF recurrence group, there was no statistically significant difference (P=0.107, P=0.867). Conclusion In our study, there is a strong association between vitD level and AF recurrence after CV. VitD deficiency might be a predictor of high risk of AF recurrence after CV and vitD supplementation during the follow-up might help the maintenance of sinus rhythm.
The Deposition and Alteration History of the Northeast Syrtis Layered Sulfates

The stratigraphy at northeast Syrtis Major [Figure 1] provides a unique temporally-constrained record of changing hydrological conditions during the Noachian–Hesperian transition on earlyMars [2]. The stratigraphy, bracketed by the mid-Noachian Isidis Basin-forming impact and mid-Hesperian Syrtis Major lavas [4], contains layered sulfates superposed atop Noachian basement units altered to carbonates and clays. The sulfate unit is recessive and layered at meter-scale, with some areas containing boxwork polygonal ridges. It is capped by lava flows contiguous with the Syrtis Major volcanic province. The upward progression from alkaline to acidic aqueous environments (and ultimately to capping lavas with no evidence of pervasive alteration) is characteristic of the planet’s first billion years [e.g. 1, 5]. An understanding of the depositional environment and alteration history of the layered sulfate unit can help trace the evolution of the early Martian surface environment. We assess detailed structural, mineralogical, andmorphological observations of the layered sulfates against a range of possible formation mechanisms (e.g. lava flow, ash fall, lacustrine deposition). The layered sulfates were likely deposited as bedded sediments gently draping the Noachian basement, and underwent diagenetic volume-loss fracturing and acid-sulfate alteration.

Challenges in the Development of Mobile P2P Applications and Services

: The recent trends of decentralizing enterprise applications toward the new peer-to-peer (P2P) architecture and the fast growth of wireless communication lead to a new tendency of combining these technologies to inherit their great advantages of mobility, reliability, flexibility and scalability. However, this technological integration raises a large number of new challenges and issues to be addressed. This paper focuses on the challenges of the development of enterprise mobile applications and services based on P2P architecture. Using selected results from related projects, we present and analyze these important issues and also propose an exemplary solution to address some of these issues.
Student Loans and Social Mobility

Students of poor families invest much less than rich families in college education. To assess the role of financing constraints and subsidy schemes in explaining this gap, I structurally estimate an IO/finance model of college choice in the presence of financing frictions. The estimation uses novel nationally representative data on US high-school and college students. I propose a novel identification strategy that relies on bunching at federal Stafford loan limits and differences between in- and out-of-state tuition. I find that the college investment gap is mainly due to fundamental factors—heterogeneity in preparedness for college and the value-added of college—rather than financing constraints faced by lower-income students. Making public colleges tuition-free would substantially reduce student debt, but it would disproportionately benefit wealthier students, and it would entail more than $15B deadweight loss per year by distorting college choices. Expanding Pell grants, in contrast, would benefit lower-income students at a much lower cost.

Trichoepithelioma is a benign cutaneus tumour originatsing from hair follicles. It is most commonly found on the face and scalp. Histopathologic examination was comsposed of band-like nests of basaloid cells showing pesripheral palization, abortive hair papilla and horn cysts in a fibrocellular stroma. A 82-year-old woman applied for a 10-year old groin mass that recently slowly growing. The lesion was excised and it was diagnosed as giant solitary trichoephitelioma.
Differential regulation of genes co-involved in aroma production and stress amelioration during salt acclimation in indica rice cultivars

The present study investigated the effects of salt acclimation on the expression of genes, viz., proline dehydrogenase ( PDH ), Δ 1 -pyrroline-5-carboxylate-synthetase ( P5CS ), P5C dehydrogenase ( P5CDH ), ornithine aminotransferase ( OAT ), betaine aldehyde dehydrogenase 1 ( BADH1 ), BADH2 , triose phosphate isomerase ( TPI ), ornithine decarboxylase ( ODC ), arginine decarboxylase ( ADC ), S-adenosyl-methionine decarboxylase ( SAMDC ), spermidine synthase ( SPDS ), spermine synthase ( SPMS ), diamine oxidase ( DAO ) and polyamine oxidase ( PAO ) in four indigenous aromatic varieties, viz., Tulaipanji (TP), Radhunipagal (RP), Kalonunia (KN) and Gobindobhog (GB) along with a non-aromatic cultivar, IR-64. The PDH , P5CS , P5CDH and OAT expression showed the regulation of the P5C pathway of aroma synthesis, with OAT appearing to regulate the crosstalk between the P5C and the polyamine (PA) pathway for the production of aroma. The role of PA pathway was further validated by monitoring the expression of ODC , ADC , SAMDC , SPDS , SPMS , DAO and PAO . The BADH2 expression reflected the fact that the enzyme encoded by the gene was directly and negatively associated with aroma content in rice. The TPI expression established that the enzyme encoded by this gene leading to the synthesis of methylglyoxal (MG) is also a key regulator for aroma synthesis. The current study established the varietal differences in the expression of the aforementioned genes in the selected rice cultivars. The salt-stressed aromatic varieties followed the P5C pathway to synthesize aroma. TP and RP exhibited the capability to generate aroma via PA-dependent pathway. Salt-stressed KN, on the contrary, accumulated higher BADH2 and lower TPI transcripts, which correlated with our previous report of KN accumulating low aroma during salinization due to efficient metabolite channelization towards stress amelioration.
VaMEx-LAOLa-Valles Marineris Exploration Lokales Ad-hoc Ortungs- und Landesystem

The DLR Space Agency studies how to explore the Valles Marineris on planet Mars. The interest in this area arises since the area is poorly investigated. This is due to the harsh topology in this region with deep canyons and high mountains, making it even more interesting for scientist. The mission concept foresees the use of a swarm of multiple UAVs (Unmanned Aerial Vehicle) and UGVs (Unmanned Ground Vehicle) that will be brought in a lander. All swarm members act in a cooperative way, i.e. some members explore the terrain and telling other members, where an interesting feature can be found. Very important subsystems of this mission are the location determination system and the communication system, which are subject of VaMEx-LAOLa, a project funded by the DLRagency (FKZ: 50NA1527). The position determination is realized in two steps. The relative position between all members will be determined ad-hoc from exploration start using radio waves. The global position and orientation is analyzed in a later mission phase by use of a star camera. The communication system will establish a data link between all swarm members. Within this paper, the technical implementation and status of LAOLa is presented.
Racial/Ethnic Difference in Risky Assets Ownership After the Financial Crisis

The purpose of this study is to investigate risky assets ownership after the financial crisis by race/ethnicity using the 2010 Survey of Consumer Finances (SCF) datasets. The results indicate that 65% of White, 38% of Black, 31% of Hispanic, and 61% of Asian/Other households own one or more risky high-return assets such as stock, business assets, and investment real estate. Logistic regression analysis suggests that even after controlling for income, risk tolerance, education, and other factors, Black, Hispanic, and Asian/Other households are less likely to hold risky assets than White households. Based on results from the decomposition methods, if the households with respondents choosing one of these three identifications had the same demographic and economic characteristics as White households, the racial/ethnic gap in risky assets ownership would be narrowed to a large degree.
Technology Choice and the Long- and Short-Run Armington Elasticity

This paper studies the international transmission of productivity shocks when the Armington elasticity is endogenized through firms' technology choice. With costly adjustment, technology choice allows for a low short-run elasticity and a high long-run elasticity. I provide analytical results which demonstrate how technology choice provides a solution to the Backus-Smith puzzle - the observed negative correlation between relative consumption and the real exchange rate. I then embed technology choice in a quantitative model of international trade with heterogeneous firms and endogenous producer entry. When the cost of adjustment is parameterized to match the correlation between relative consumption and the real exchange rate, the cross-correlation of GDP is higher than the cross-correlation of consumption, thereby providing a solution to the quantity anomaly.
Effect of Drought Stress and Thermal Pre-treatment on the In vitro Shoot Development of Solanum lycopersicum L.

Tomato is one of the popular vegetables in the world. However, drought has become more serious in recent years. Drought strongly reduced the development and yield of tomato. Thus, the effect of drought stress condition (½ Murashige and Skoog’s medium supplemented with 35 g.L-1 mannitol) and thermal pre-treatment (45 (C for 120 min) on in vitro shoot development of Solanum lycopersicum L. were studied to improve the drought-tolerant of tomato. Morphological, physiological and biochemical changes during the development of in vitro shoot in the drought stress condition were analyzed. Then, leaves of the shoot that pre-treated at 45 (C for 120 min and developed on the drought stress condition were cultured on ½ MS medium supplemented with 20 g.L-1 sucrose, 0.1 mg.L-1 Indole acetic acid, 2 mg.L-1 zeatin and 35 g.L-1 mannitol to regenerate the drought-tolerant shoots. In the drought stress condition (½ MS medium with 35 g.L-1 mannitol), the height of shoot, the number of leaves, and the total leaf area were decreased by approximately 50 % compared to control (½ MS medium without mannitol). Besides, the leaf midrib thickness and the vascular bundle width of the leaf in drought stress were smaller than those of the control. The leaf midrib thickness and the leaf vascular bundle width in drought stress condition were 953.30 (m and 320.21 (m, compared to 1243.80 (m and 410.15 (m in that of control. Chlorophyll fluorescence occurs in some parenchyma cells near the midrib vascular bundle of treated leaves instead of all parenchyma cells in control leaves. Under the drought stress condition, chlorophyll content, photosynthetic intensity and cytokinin activity of leaf were strongly decreased but respiration intensity, the content of carotenoid and proline, especially the activity auxin and abscisic acid were increased. Thermal pre-treatment stimulated shoot regeneration (2.53 shoots/leaf explant) while there was no shoot regenerated from the leaf of the control plant. The shoots regenerated by this method grew well in the drought stress condition.
Role of urban patterns for building generalisation: An application of AGENT

The AGENT prototype results from the european project AGENT ended in 2000. It is a significant progress in automatic building generalisation in urban areas, as shown in [BAR 01] and [DUC 01]. At IGN, the french mapping agency, some recent developments such as the AGENT prototype are more and more ported to map production lines: it shows the interest of production for new tools and creates new needs of development improvements. That is why some recent works in COGIT deal with urban analysis to improve contextual generalisation for 1:50000 scaled maps. This paper presents how this results have been gathered together and adapted to be integrated with the AGENT prototype.

Mediating effects of self-esteem in the links of attachment styles with social media addiction among university students

Objective: Today, internet and social media are indispensable parts of our lives. Besides the advantages of social media, some individuals have begun to develop and suffer from Social Media Addiction (SMA) which was associated with dysfunctions in academic and/or work domains. Although outcomes of SMA are relatively investigated more widely, antecedents of it have not been studied extensively yet. The aim of the present study was to investigate the effects of secure, fearful, and preoccupied attachment styles on SMA and the mediating role of self-esteem in the links of attachment styles with SMA. Method: Data were collected from 455 university students (300 females, 155 males) who volunteered to complete the survey packages which included Social Media Addiction Scale, Relationships Questionnaire and Rosenberg Self-Esteem Scale. Results: The data were analyzed by using Structural Equation Modeling (SEM) and moderated multiple regression. The results revealed that preoccupied and fearful attachment had significant positive direct effects on SMA. While the link of preoccupied attachment with SMA was partially mediated, the relationship between secure attachment and SMA was fully mediated by self-esteem. In addition, exploratory analyses revealed that gender moderated the relationship between self-esteem
OpenCrowd: A Human-AI Collaborative Approach for Finding Social Influencers via Open-Ended Answers Aggregation

Finding social influencers is a fundamental task in many online applications ranging from brand marketing to opinion mining. Existing methods heavily rely on the availability of expert labels, whose collection is usually a laborious process even for domain experts. Using open-ended questions, crowdsourcing provides a cost-effective way to find a large number of social influencers in a short time. Individual crowd workers, however, only possess fragmented knowledge that is often of low quality. To tackle those issues, we present OpenCrowd, a unified Bayesian framework that seamlessly incorporates machine learning and crowdsourcing for effectively finding social influencers. To infer a set of influencers, OpenCrowd bootstraps the learning process using a small number of expert labels and then jointly learns a feature-based answer quality model and the reliability of the workers. Model parameters and worker reliability are updated iteratively, allowing their learning processes to benefit from each other until an agreement on the quality of the answers is reached. We derive a principled optimization algorithm based on variational inference with efficient updating rules for learning OpenCrowd parameters. Experimental results on finding social influencers in different domains show that our approach substantially improves the state of the art by 11.5% AUC. Moreover, we empirically show that our approach is particularly useful in finding micro-influencers, who are very directly engaged with smaller audiences.
Approaches for enhancing tile-based mapping with cartographic generalisation

1. Motivation As part of the progression of information age, internet users are increasingly able to participate actively in the appearance and content of the internet, what has been resulted in the term "Web 2.0" (O’Reilly 2005). As a result, some projects have been initiated prescribing the collection of spatial data with the help of a crowd, what is now known mainly as crowdsourcing (Martin et al. 2008). That evolved a kind of “neogeography” (Turner 2006) respectively “neocartography” (Gartner and Schmidt 2010) which expresses in form of “maps 2.0” (Crampton 2009). OpenStreetMap is probably the most well known project in this context and is meanwhile well established. Now a large number of maps exist, that are derived solely from that user-generated (Goodchild 2007) “geomassdata” (Zipf 2009). But many of these maps can only be used with low requirements to the graphical quality (Zollinger 2008). One reason for this can be seen in a lack of applicability of cartographic generalisation. Probably the most widely used web mapping method is the representation in form of interactive, "free" scalable map displays, colloquial called “slippy map” (e.g.: OpenPisteMap, OpenCycleMap, WheelMap, OpenTopoMap, etc.). These are usually created completely automatic and displayed on the internet as tile-based map. The processing of such huge datasets needs adequate spatial data structures for fast and efficient data processing respectively generalisation. This is regularly a tile-based structure for slippy maps. Cartographic generalisation has to fit to this structure, especially for automatic computation, update and on demand request of tiles. Changes in the corresponding data as well as the query of single tiles happen within an heterogeneous spatial frequency. Frequently obtained tiles get processed regularly and scarce obtained tiles are only processed on demand. In consequence, generalisation should just be applied to local changes and not to the whole dataset. Therefore, it is important to enhance the automatic computation of tiles, colloquial called “rendering”, with concepts of on-the-fly generalisation, for keeping the tile-based mapping process flow completely automatic. However, it must be considered that the claim, of keeping the process flow automatic, cannot be fully satisfied for all requirements of cartographic generalisation. For this reason, it is necessary to include also supporting concepts of data pre-processing, like MRDB, in the deliberations.
First-price auctions with budget constraints

Consider a first-price sealed-bid auction with interdependent valuations and private budget constraints. Focusing on the two-bidder case, we identify new sufficient conditions for the existence of a symmetric equilibrium in pure strategies. In equilibrium, agents may adopt discontinuous bidding strategies that result in a stratification of competition along the budget dimension. Private budgets can simultaneously lead to more aggressive bidding (a high-budget agent leverages his wealth to outbid rivals) and more subdued bidding (competition becomes less intense among bidders at distinct budget levels). The presence of budget constraints may lead to multiple symmetric equilibria in the first-price auction.
