"My choice, my voice, my opinion" : an exploration of a strengths-based model used with youth in hip hop therapy : a project based upon an investigation at Beats, Rhymes, & Life (BRL)

The purpose of this study was to examine how the Academy program at Beats, Rhymes, & Life, Inc. (BRL) utilizes a strength-based therapeutic approach. This study focused on identifying facets of a strength-based model utilized by the Academy, and exploring the effect of a strengths-based approach on participants. Using semi-structured interviews with seven current and past Academy members, the study found that the strengths-based approach positively impacted all participants in three distinct ways: (1) Valuing multiple forms of knowledge in a non-hierarchical manner, which included processes related to collaboration, self-directed learning, and use of a multicultural perspective, (2) Honoring client and communities as experts on themselves and capable of healing themselves, which included participants identifying healing processes amongst their community and the impact of healing through art and expression, and (3) Reframing the pathological “at risk” model to a strength-based model of resilience, which included identifying processes related to highlighting personal strengths, reframing youth form “at-risk” to “at-promise” and increasing perceived self-esteem and confidence. Implications for social practice highlight the benefits that a strength-based approach provides for the Academy and provides a template for best practice in therapeutic groupbased agency work. “MY CHOICE, MY VOICE, MY OPINION”: AN EXPLORATION OF A STRENGTHS-BASED MODEL USED WITH YOUTH IN HIP HOP THERAPY A project based upon an investigation at Beats, Rhymes, & Life (BRL), Oakland, California, submitted in partial fulfillment of the requirements for the degree of Master of Social Work.

Optimal Design and Verification of a PM Synchronous Generator For Wind Turbines

This study reports the analytical computation including performance characteristics under no-load condition in combination with coupled 2D electromagnetic field-circuit analysis of a 4kW direct drive permanent magnet synchronous generator (PMSG) to be used in micro-scale wind turbine applications. The specifications such like stack length, skew and magnet offset of PMSG are optimized by using parametric approach including multi-objective design optimization. It describes the methodology to gain required output performance such as output power, load voltage and maximum efficiency of the wind generator. Based on the optimized design, the model has been exposed to some transient coupled-field circuit analyses based on variable wind flow speed under no-load conditions. The experimental results verified the effectiveness of the employed simulations model related to finite element methods and analytical studies.
Quality Of Public Spaces And Sustainable Urban Development: Success And Failures In Fighting Social Exclusion

Sustainable Urban Development embeds the three pillars of sustainability: environmental, social and economic. The European Commission position on Sustainable Urban Development reflects this concept, recommending an integrated approach paying attention to several intertwined factors, including the quality of public spaces. In European cities poverty issues and exclusion are particularly acute. Inclusive growth is one of the main driver of the Europe 2020 strategy, thus, it is expected that actions for fighting social exclusion are significant in deprived urban areas. However, in the EC approach still policies for social inclusion tend to remain relegated to the socio- economic sphere, with a weak link to the physical element as specific matter of concern. This paper aims at discussing the role played by the spatial quality of public spaces in supporting social integration, by focussing on a case study in Italy. More in details, the paper discusses the effects of public policies undertaken in the 1990s by the City of Reggio Calabria to reduce poverty for Roma people, by displacing those inhabiting squalid and unhealthy camps to council housing in two neighbourhoods with a different quality of public spaces. In one area the displacement happened successfully, in the other, social issues plague the community. The paper aims at investigating the influence of the quality of public spaces on the displacement outcomes. The research methodology is mainly qualitative and is based on field work complemented by photo survey and interviews. The paper suggests that the spatial quality of the public spaces might have contributed to exacerbate social conflict and detachment in the unsuccessful case. It is therefore recommended to incorporate a significant component on public space inclusive design in any socio-economic intervention aimed at overcoming social exclusion.
Gain Enhancement of Series Feed Square Patch Microstrip Antenna Array for S band & C Band Applications

All rights reserved by www.ijsrd. com 449 Gain Enhancement of Series Feed Square Patch Microstrip Antenna Array for S band & C Band Applications Ravikant Bharati Surendra Kumar Sriwas Dept. of Electronics & Communication Engineering Bundelkhand Institute of Engineering & Technology, Jhansi, India Abstract— Gain is the ability of an antenna to concentrate the radiated power in a desired direction. Only small gain can be achieved by single antenna that is why, antenna arrays are required to improve the gain by using different feed networks. This paper describes the design and performance of a series feed antenna array. The operating frequency of 2.4GHz is used. The aim of this paper is to improve the gain of a series feed antenna array. Line feed is used for designing single antenna, 2x1 & 4x1 microstrip antenna array. These series feed microstrip antenna arrays are useful for both S and C band. The proposed antenna is simulated by IE3D version 9.0 Zealand simulation software based on method of moments.

Image Classification Using Fusion of Holistic Visual Descriptions

An efficient approach for scene classification is necessary for automatically labeling an image as well as for retrieval of desired images from large scale repositories. In this paper machine learning and computer vision techniques have been applied for scene classification. The system is based on feature fusion method with holistic visual color, texture and edge descriptors. Color moments, Color Coherence Vector, Color Auto Correlogram, GLCM, Daubechies Wavelets, Gabor filters and MPEG-7 Edge Direction Histogram have been used in the proposed system to find the best combination of features for this problem. Two state-of- the-art soft computing machine learning techniques: Support vector machine (SVM) and Artificial Neural Networks have been used to classify scene images into meaningful categories. The benchmarked Oliva-Torralba dataset has been used in this research. We report satisfactory categorization performances on a large data set of eight categories of 2688 complex, natural and urban scenes. Using a set of exhaustive experiments our proposed system has achieved classification accuracy as high as 92.5% for natural scenes (OT4) and as high as 86.4% for mixed scene categories (OT8). We also evaluate the system performance by predictive accuracy measures namely sensitivity, specificity, F-score and kappa statistic.
HIL evaluation of control unit in grid-tied coverters

Hardware-in-the-Loop (HIL) emulation is poised to become unsurpassed design tool for development, testing, and optimization of real-time control algorithms for grid connected power electronics converters for distributed generation, active filters and smart grid applications. It is strongly important to examine and test how grid connected converters perform under different operating conditions including grid disturbances and faults. In that sense, converter’s controller is a key component responsible for ensuring safe and high-performance operation. This paper demonstrates an example how ultra-low latency and high fidelity HIL emulator is used to easily, rapidly and exhaustively test and validate standard control strategy for grid connected power electronics converters, without need for expensive hardware prototyping and laboratory test equipment.

Study of Catalase Enzyme in Methylotrophic Yeasts

ABSTRACT Catalase enzyme was explored in three methylotrophic yeast strains Pichia pastoris X-33, Hansenula polymorpha CBS 4732 and Pichia pini NBIMCC 8360 during batch-wise growth on different carbon sources. For investigation of compartmentalization of the enzyme within yeast cells a mitochondrial fraction from each strain was isolated. Peroxisomal and mitochondrial import of catalase enzyme was tested quantitatively by subcellular fractionation followed by enzyme activity assays. Efficient catalase import into peroxisomes was observed when cells were cultivated under peroxisome-inducing conditions (i.e. growth on methanol), whereas more significant catalase activity was measured in mitochondria when cells were grown on polyvalent alcohol glycerol that favor respiration and ROS (reactive oxygen species) accumulation within this organelle. When yeast cells utilize glucose the catalase enzyme is relatively equal distributed between the two compartments (peroxisomes and mitochondria). Results indicated that mitochondrial matrix in methylotrophic yeasts possess in situ mechanism for scavenging of ROS represented by Mn SOD and mitochondrial catalase.
The effects of magnetic fields and protostellar feedback on low-mass cluster formation

We present a large suite of simulations of the formation of low-mass star clusters. Our simulations include an extensive set of physical processes -- magnetohydrodynamics, radiative transfer, and protostellar outflows -- and span a wide range of virial parameters and magnetic field strengths. Comparing the outcomes of our simulations to observations, we find that simulations remaining close to virial balance throughout their history produce star formation efficiencies and initial mass function (IMF) peaks that are stable in time and in reasonable agreement with observations. Our results indicate that small-scale dissipation effects near the protostellar surface provide a feedback loop for stabilizing the star formation efficiency. This is true regardless of whether the balance is maintained by input of energy from large scale forcing or by strong magnetic fields that inhibit collapse. In contrast, simulations that leave virial balance and undergo runaway collapse form stars too efficiently and produce an IMF that becomes increasingly top-heavy with time. In all cases we find that the competition between magnetic flux advection toward the protostar and outward advection due to magnetic interchange instabilities, and the competition between turbulent amplification and reconnection close to newly-formed protostars renders the local magnetic field structure insensitive to the strength of the large-scale field, ensuring that radiation is always more important than magnetic support in setting the fragmentation scale and thus the IMF peak mass. The statistics of multiple stellar systems are similarly insensitive to variations in the initial conditions and generally agree with observations within the range of statistical uncertainty.
The Effect of Quiz Frequency on Course Performance and Its Relationship with Class Attendance

To investigate the effect of quiz frequency on the course performance of Iranian university students of English, the mean scores of five groups of subjects were compared using a balanced one-way ANOVA procedure. Analyses revealed that quizzes significantly improve course performance. With some exceptions, it was also found that the more frequently the subjects were quizzed, the better their course performance became. To study the relationship between quizzes and class attendance, the absences of the same five groups of subjects were regularly checked and compared using the Chi-square procedure. Results showed that there is an inverse relationship between quiz frequency and the number of absences from class.
Belief di↵usion in social networks

We report the results of a laboratory experiment investigating propagation of beliefs in a social network. During the experiment, participants faced several questions having objectively correct answers and could update their answers several times based on aggregate information about answers chosen by their neighbours. One of the novelties of the experiment was that the binary choices faced by participants were augmented to include an “I do not know” option and incentives to choose it when they felt indi↵erent between the actual options. We observe that the dynamics of decisions in the network strongly depends on the question type, logical or factual. The results also indicate that propagation of beliefs can be more accurately described by a threshold model rather than models of probabilistic contagion. However, in contrast with assumptions underlying standard threshold models, our results suggest that it is not the larger proportion of neighbours that is driving participants’ choices but the di↵erence between the proportions of neighbours opting for the competing options.
Regional uncertainty of GOSAT XCO 2 retrievals in China: quantification and attribution

Abstract. The regional uncertainty of the column-averaged dry air mole fraction of CO2 (XCO2) retrieved using different algorithms from the Greenhouse gases Observing SATellite (GOSAT) and its attribution are still not well understood. This paper investigates the regional performance of XCO2 within a latitude band of 37–42° N segmented into 8 cells in a grid of 5° from west to east (80–120° E) in China, where typical land surface types and geographic conditions exist. The former includes desert, grassland and built-up areas mixed with cropland; and the latter includes anthropogenic emissions that change from small to large from west to east, including those from the megacity of Beijing. For these specific cells, we evaluate the regional uncertainty of GOSAT XCO2 retrievals by quantifying and attributing the consistency of XCO2 retrievals from four algorithms (ACOS, NIES, OCFP and SRFP) by intercomparison. These retrievals are then specifically compared with simulated XCO2 from the high-resolution nested model in East Asia of the Goddard Earth Observing System 3-D chemical transport model (GEOS-Chem). We also introduce the anthropogenic CO2 emissions data generated from the investigation of surface emitting point sources that was conducted by the Ministry of Environmental Protection of China to GEOS-Chem simulations of XCO2 over the Chinese mainland. The results indicate that (1) regionally, the four algorithms demonstrate smaller absolute biases of 0.7–1.1 ppm in eastern cells, which are covered by built-up areas mixed with cropland with intensive anthropogenic emissions, than those in the western desert cells (1.0–1.6 ppm) with a high-brightness surface from the pairwise comparison results of XCO2 retrievals. (2) Compared with XCO2 simulated by GEOS-Chem (GEOS-XCO2), the XCO2 values from ACOS and SRFP have better agreement, while values from OCFP are the least consistent with GEOS-XCO2. (3) Viewing attributions of XCO2 in the spatio-temporal pattern, ACOS and SRFP demonstrate similar patterns, while OCFP is largely different from the others. In conclusion, the discrepancy in the four algorithms is the smallest in eastern cells in the study area, where the megacity of Beijing is located and where there are strong anthropogenic CO2 emissions, which implies that XCO2 from satellite observations could be reliably applied in the assessment of atmospheric CO2 enhancements induced by anthropogenic CO2 emissions. The large inconsistency among the four algorithms presented in western deserts which displays a high albedo and dust aerosols, moreover, demonstrates that further improvement is still necessary in such regions, even though many algorithms have endeavored to minimize the effects of aerosols scattering and surface albedo.
Influence of composting and poultry litter storage methods on mineralization and nutrient dynamics.

Poultry litter poses serious environmental threats and health hazards while composting offers the convenient and acceptable means of its recycling. This study was carried out by considering the importance of proper storage an d composting of poultry litter (PL) for its nutrient conservation and stability. Five storage methods were compared for their effects on nutrient dynamics in PL under composting and un-composting conditions. Storage methods included: shed, covered (plastic sheet), open-air, pit, and lined floor. The pile / pit size was 2 m × 2 m × 1 m (L × W × H or D), and the quantity of poultry litter in each one was 500 kg. Composite PL samples were collected after an interval of 15 days until 90 days for the determination of organic C, macro- (N, P and K) contents. The results depicted significant successive reduction of organic C contents / C:N ratio and improvement in macro - and micro-nutrient concentration in the processed PL with increased storage time both under composting and un-composting conditions. Among the storage methods, PL composted under plastic cover resulted to highest nutrient contents and the lowest C:N ratio; while shed storage without composting gave the poorest results. Finally, the lowest values of C:N were found under in-pit and lined- floor storage which differed significantly from under -shed storage with maximum value. Therefore from this study it is concluded that composting of poultry litter along with plastic sheet cover provides the best storag e condition to conserve nutrients.
Shimura and Teichmüller curves

We classify curves in the moduli space of curves $M_g$ that are both Shimura and Teichmuller curves: for both $g=3$ and $g=4$ there exists precisely one such curve, for $g=2$ and $g \geq 6$ there are no such curves. We start with a Hodge-theoretic description of Shimura curves and of Teichmuller curves that reveals similarities and differences of the two classes of curves. The proof of the classification relies on the geometry of square-tiled coverings and on estimating the numerical invariants of these particular fibered surfaces. Finally, we translate our main result into a classification of Teichmuller curves with totally degenerate Lyapunov spectrum.
Determinants of Ante-natal Care, Place of Delivery and Post-natal Care Services of Rural Women in Northern Nigeria

Aim: This study aimed to identify the determinants of Ante-natal postnatal using a structured questionnaire and analyzed using IBM SPSS. The examined attendance at Ante-natal care services, place of delivery and attendance of post-natal care as primary outcomes. Binary logistic regression using forced entry was used to compute the determinants of Ante-natal care services, place of delivery and post-natal services. The of level of significance was set at p ≤ 0.05. Results: Majority 258 (80.1%) of the mothers attended ante-natal care but only 45 (14%) of the mothers delivered in the hospital while only 104 (32.3%) went for post-natal visit. Determinants of Ante-natal care services, place of delivery and post-natal care was found to be maternal education and socioeconomic status. Mothers with formal education were twice more to attend Ante-natal care services (p ≤ 0.05, OR = 2.11, 95% C.I = 0.99 – 4.450. Mothers with non-formal education were more likely to deliver at home (p = 0.01, OR = 0.29, 95% C.I = 0.14 – 0.59) while those in the upper class were more to attend post-natal care (p = 0.03, OR = 1.81, 95% C.I = 1.05 – 3.13). Conclusion: The study demonstrates that maternal education and socioeconomic status influence Ante-natal care services, place of delivery and post-natal services. Therefore, there is need to encourage female-child education and women should be empowered to improve their socioeconomic status so that they can take charge of their health.
Consequences of large-scale salinity alteration during the Deepwater Horizon oil spill on subtidal oyster populations

Response actions associated with oil spills often have significant impacts on ecological communities. During the 87 d long Deepwater Horizon oil spill, the State of Louisiana (USA) released vast quantities of Mississippi River water into 2 estuarine basins (Barataria Bay and Black Bay/Breton Sound) in response to the approach of oil. We assessed the impact on subtidal oyster populations of this novel oil spill response action using 3 independent methods: (1) comparison of fisheries-independent post-spill densities to a pre-spill temporal baseline; (2) comparison of oyster density collected during natural resource damage assessment sampling between the area of maximal freshwater impact and reference areas in the 2 basins; and (3) estimation from a doseresponse model derived from an analysis of an in situ mark and recapture study conducted in 2010 to assess the relationship between salinity and oyster mortality. A substantial portion of both basins (483 km2 of Barataria Bay and 362 km2 of Black Bay/Breton Sound) experienced prolonged periods of very low (<5 ppt) salinity in 2010 that lasted at least 1 mo longer than the average duration of low salinity between 2006 and 2009. The 3 approaches all indicate that dramatic losses occurred in the number of market-sized (>75 mm) oysters as a result of a system-wide lowering of salinities, with an estimated 1.16 to 3.29 billion market-equivalent oysters lost. The efficacy of the large-scale response action of altering hydrographic conditions during the summer oyster growth period should be examined in light of the major perturbation to oyster communities.
Synthesis of a Porphyrin Derivative Covalently linked to Nickel Aza-macrocycle Complex

A porphyrin derivative covalently linked to Ni aza-macrocycle complex has been prepared. Absorption spectrum of porphyrin-Ni aza-macrocycle dyad ( λa max =230, 416 nm) was observed to similar to a sum of those of tetratolylporphyrin ( λa max =419 nm) and Ni aza-macrocycle ( λa = 227 nm), indicating no electronic interaction between porphyrin and Ni aza-macrocycle moieties. Fluorescence quantum yield of dyad ( Φf = 0.10) was same to that of tetratolylporphyrin ( Φf =0.10). Photoinduced intramolecular electron transfer or energy transfer from excited porphyrin moiety to Ni(II) aza-macrocycle moiety should be very inefficient in dyad.
