3rd Grade Bullying Assessment

In the present study the sensitivity of violence of 3rd graders (N=106) was examined. Seven classes from two schools in different districts received a bullying questionnaire. Children scores on the questionnaire were analyzed through a coding system. Gender differences were found within the sensitivity of violence. Also, sensitivity scales were made in regards to each school district. Where bullying takes place in the school was also found

Evaluation Of The Profitability Of Companies Financed By Venture Capital (CVC) Listed On The French Market

This paper examines changes in profitability of 146 CVC listed on the French market. The results show disappointing post-IPO profitability. The decline in performance ranges from 9.5% to 32% over a two-year period following the launch on the stock exchange. It also appears that the decline in operating performance is less significant for CVC compared with non CVC over the same period. An analysis of this underperformance shows that CVC supported by reputed VCF manage to limit the decline in operating performance compared to those supported by non-reputed VCF

The Evolution Of Risk Premiums In Emerging Stock Markets: The Case Of Latin America And Asia Region

This paper employs a conditional version of the International Capital Asset Pricing Model (ICAPM) to investigate the determinants of regional integration of stock markets in Latin America and Asia over the period 1996-2008. This model allows for three sources of time-varying risks: common international market risk, exchange rate risk, and regional market risk. At the empirical level, we make use of the asymmetric multivariate BEKK-GARCH of Baba et al.’s (1990) process to simultaneously estimate the ICAPM. Our results show that the currency risk premium is the most important component of the total premium followed by the global market premium. As for the regional risk, our findings show that it is significantly priced for our studied emerging regions but its contribution to the total risk premium is weak

Industry 4.0 at Brazilian modular consortium:work, process and knowledge in engine supply chain

Paper aims: This paper aims to discuss Industry 4.0 (I4.0) impacts on the Brazilian Modular Consortium (BMC) assembly lines related to work – issues correlated with human resources; production – physical resources used in production process; knowledge – associated with creation and sharing of knowledge. Originality: Findings explore I4.0 research opportunities related to work and human factors on assembly lines. In lieu of gaps in literature, this research further discusses management challenges to support digital transformation and impacts on workers and organizations. Research method: A case study on Engine Value Chain (EVC) of BMC, which includes MWM, engine manufacturer; Powertrain, engine assembler at BMC; Volkswagen Truck & Bus, BMC responsible. Semi-structured interviews were conducted with four senior managers responsible for I4.0 implementation. Responses were treated via content analysis. Main findings: The interviewees highlight work and human factors as important for I4.0 implementation, which include workers tasks, skills, nature of work, human resource development, hiring process and organizations strategies. It was also found that knowledge sharing poses a huge challenge. Implications for theory and practice: The findings contribute with academic interest on work, production and knowledge impacts on assembly lines, and with practitioners on issues related to I4.0 implementationCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Estadual Paulista, SPUniversity of BirminghamUniversidade Estadual Paulista, SPCAPES: #88887.310463/2018-0

Islamic Finance: A Review Of The Literature

In recent years, a number of Islamic banks have been created to cater to the growing demand, driven by globalization and the vast wealth of some Muslim states in the Middle East and Southeast Asia, and Islamic finance has moved from a niche position to become a mainstream component of the global banking system. Islamic banking refers to a financial system which is consistent with principles of Islamic law (or sharia) and guided by Islamic ethics. A large amount of research has been undertaken into this subject. This paper presents islamic finances role in the new world order

Functional engineering of hybrid heterostructures for application in electronic, optical and optoelectronic nanostructured devices

Interfacing materials with different intrinsic chemical-physical characteristics allows for the generation of a new system with multifunctional features. Here, this original concept is implemented for tailoring the functional properties of bi-dimensional black phosphorus (2D bP or phosphorene) and organic light-emitting transistors (OLETs). Phosphorene is highly reactive under atmospheric conditions and its small-area/lab-scale deposition techniques have hampered the introduction of this material in real-world applications so far. The protection of 2D bP against the oxygen by means of functionalization with alkane molecules and pyrene derivatives, showed long-term stability with respect to the bare 2D bP by avoiding remarkable oxidation up to 6 months, paving the way towards ultra-sensitive oxygen chemo-sensors. A new approach of deposition-precipitation heterogeneous reaction was developed to decorate 2D bP with Au nanoparticles (NP)s, obtaining a “stabilizer-free” that may broaden the possible applications of the 2D bP/Au NPs interface in catalysis and biodiagnostics. Finally, 2D bP was deposited by electrospray technique, obtaining oxidized-phosphorous flakes as wide as hundreds of µm2 and providing for the first time a phosphorous-based bidimensional system responsive to electromechanical stimuli. The second part of the thesis focuses on the study of organic heterostructures in ambipolar OLET devices, intriguing optoelectronic devices that couple the micro-scaled light-emission with electrical switching. Initially, an ambipolar single-layer OLET based on a multifunctional organic semiconductor, is presented. The bias-depending light-emission shifted within the transistor channel, as expected in well-balanced ambipolar OLETs. However, the emitted optical power of the single layer-based device was unsatisfactory. To improve optoelectronic performance of the device, a multilayer organic architecture based on hole-transporting semiconductor, emissive donor-acceptor blend and electron-transporting semiconductor was optimized. We showed that the introduction of a suitable electron-injecting layer at the interface between the electron-transporting and light-emission layers may enable a ≈ 2× improvement of efficiency at reduced applied bias

The Great Textual Hoax: Boosting Sampled String Matching with Fake Samples

Sampled String Matching is presented as an efficient solution to the string matching problem, aiming to tackle the space constraints of indexed string matching while purportedly reducing search times for online solutions. Despite the problem’s inception dating back to 1991, practical solutions have only recently emerged. These purportedly accelerate online searches by up to 35 times compared to conventional methods, achieved through a partial index occupying a mere 5% of the text size. This paper delves into the intricacies of one of the latest and most effective text sampling techniques, character distance sampling, which revolves around sampling distances between characters of a selected alphabet within the text. Specifically, we introduce fake samples while remaining honest! In other words, the study reveals that, interestingly, strategically introducing fake samples within the sampled sequence slashes the required index space by almost half, just avoid compromising the algorithm’s correctness. Additionally, since efficiency is everything, this approach, in turn, purportedly enhances the algorithm’s efficiency under specific conditions
