Shelter Development Through Cooperatives: A Strategy for Poverty Alleviation and Slum Improvement for Asia and the Pacific Region

The research traces the flow of humanity from the urban areas to the cities thus creating severe economic and social problems in the cities thus leading to homelessness; lack of sanitation; health hazards; crimes; vandalism; drugs; children wandering around and a host of problems which civic society leaders are not willing or able to act upon because slums are also vote banks for politicians

The Current Standing and Future Prospects of ARTS and Culture in Ethiopia

This research article explores the current state of affairs of arts and culture sector in Ethiopia. An in-depth analysis of various dimensions of art and culture highlights where the country is presently lacking in governance and socio-economic progress in the sector. A qualitative research was carried out to collect primary data. 52 respondents were chosen to be interviewed from Bahir Dar University by the method of quota sampling and the results were analyzed. Secondary data was also analyzed through academic literature from universities in Ethiopia, reports from government and development organizations. Survey results and existing academic literature have guided to single out major hindrances to this sector. In this research it can be confirmed, that the arts and culture sector needs a major intervention in terms of governance and marketing. This research gives out a very structural strategy, based on cultural governance, cultural economics and strategies of new business development as it pillars to support the prosperity of this sector in Ethiopia. The existing academic research provides data on different arts and culture and problems which are specific to a particular region of the country. Whereas this article goes a step further in enforcing the ordinance of cultural governance to the responsible government bodies both locally and nationally and simultaneously highlights how economic progress can be achieved through this sector. Cultural governance as a directive has never been implemented in transition economies and this article will serve as a directive for the future. This article shall be very beneficial for further research in this sector and structuring the work of government bodies, stake holders and the people involved in the sector within Ethiopia

Revisiting the Meaning of Leadership

During the past fifty years, organizational scholarship on leadership has shifted from a focus on the significance of leadership for meaning-making to the significance of leadership for economic performance. This shift has been problematic for two reasons. First, it has given rise to numerous conceptual difficulties that now plague the study of leadership. Second, there is now comparatively little attention to the question of how individuals find meaning in the economic sphere even though this question should arguably be one of the most important questions for organizational scholarship. This chapter discusses several reasons for the shift, arguing that one of the most important has been the lack of a clear definition and operationalization of meaningful economic activity. As a first step to redressing this shift, we offer a definition and operationalization of meaningful action, and we propose a typology of executive behaviors as a foundation for a systematic exploration of the meaning-making capacity of leaders. We conclude with a discussion of the relationship between the capacity of leaders to infuse meaning and the capacity of leaders to impact on performance

From Social Control to Financial Economics: The Linked Ecologies of Economics and Business in Twentieth Century America

This article draws on historical material to examine the co-evolution of economic science and business education over the course of the twentieth century, showing that fields evolve not only through internal struggles but also through struggles taking place in adjacent fields. More specifically, we argue that the scientific strategies of business schools played an essential—if largely invisible and poorly understood—role in major transformations in the organization and substantive direction of social-scientific knowledge, and specifically economic knowledge, in twentieth century America. We use the Wharton School as an illustration of the earliest trends and dilemmas (ca. 1900–1930), when business schools found themselves caught between their business connections and their striving for moral legitimacy in higher education. Next, we look at the creation of the Carnegie Tech Graduate School of Industrial Administration after World War II. This episode illustrates the increasingly successful claims of social scientists, backed by philanthropic foundations, on business education and the growing appeal of “scientific” approaches to decision-making and management. Finally, we argue that the rise of the Graduate School of Business at the University of Chicago from the 1960s onwards (and its closely related cousin at the University of Rochester) marks the decisive ascendancy of economics, and particularly financial economics, in business education over the other behavioral disciplines. We document the key role of these institutions in diffusing “Chicago-style” economic approaches—offering support for deregulatory policies and popularizing narrowly financial understandings of the firm—that sociologists have described as characteristic of the modern neo liberal regime

Angiogenesis-dependent and independent phases of intimal hyperplasia.

BACKGROUND: Neointimal vascular smooth muscle cell (VSMC) proliferation is a primary cause of occlusive vascular disease, including atherosclerosis, restenosis after percutaneous interventions, and bypass graft stenosis. Angiogenesis is implicated in the progression of early atheromatous lesions in animal models, but its role in neointimal VSMC proliferation is undefined. Because percutaneous coronary interventions result in induction of periadventitial angiogenesis, we analyzed the role of this process in neointima formation. METHODS AND RESULTS: Local injury to the arterial wall in 2 different animal models induced periadventitial angiogenesis and neointima formation. Application of angiogenesis stimulators vascular endothelial growth factor (VEGF-A165) or a proline/arginine-rich peptide (PR39) to the adventitia of the injured artery induced a marked increase in neointimal thickening beyond that seen with injury alone in both in vivo models. Inhibition of either VEGF (with soluble VEGF receptor 1 [sFlt1]) or fibroblast growth factor (FGF) (with a dominant=negative form of FGF receptor 1 [FGF-R1DN]), respectively, signaling reduced adventitial thickening induced by VEGF and PR39 to the level seen with mechanical arterial injury alone. However, neither inhibitor was effective in preventing neointimal thickening after mechanical injury when administered in the absence of angiogenic growth factor. CONCLUSIONS: Our findings indicate that adventitial angiogenesis stimulates intimal thickening but does not initiate it

Formulation And Characterization of Carageenan Gels Encapsulating Amphotericin B And Lactobacillus acidophilus Against Candidal Vaginitis

The present study is concerned with the development and characterization of bioadhesive carageenan gel encapsulating Amphotericin B and Lactobacillus acidophillus, prepared by graft co-polymeriztion against Candidal vaginitis. Intravaginal gel systems based on bioadhesive polymer (carrageenan) were characterized with respect to swelling index, bioadhesive strength, percent encapsulation and in vitro drug release antimicrobial studies. A marked increase in swelling index of gel encapsulating Lactobacillus was found to be 1.9±0.35. The percent encapsulation of drug was found to be 98.63%±.0.2% and that of Lactobacillus was 91.81 ±0.01. The viability was observed for interval of 6 hrs on trypton soya agar and showed that viability was highly conserved till 4 hrs. The antimicrobial study of gels encapsulating Amphotericin B and Lactobacillus showed that carageenan gel can inhibit Candida albicans upto a maximum extent. Bioadhesivity study also conducted for gels that showed a bioadhesivity of 84.66% ±.0.5% with drug, 88.66% ±.02% with Lactobacillus. In-vitro drug release showed a sustained type release of drug from the polymer i.e. there was initial burst of Amphotericin B up to 5 hours, after which there was a sustained release upto 10 days. Thus it has been concluded from the present study that bioadhesive gels encapsulating Amphotericin B can act as promising drug carriers along with Lactobacillus against candidal vaginitis

Association between sensory impairment and suicidal ideation and attempt: a cross-sectional analysis of nationally representative English household data

OBJECTIVES: Sensory impairments are associated with worse mental health and poorer quality of life, but few studies have investigated whether sensory impairment is associated with suicidal behaviour in a population sample. We investigated whether visual and hearing impairments were associated with suicidal ideation and attempt. DESIGN: National cross-sectional study. SETTING: Households in England. PARTICIPANTS: We analysed data for 7546 household residents in England, aged 16 and over from the 2014 Adult Psychiatric Morbidity Survey. EXPOSURES: Sensory impairment (either visual or hearing), Dual sensory impairment (visual and hearing), visual impairment, hearing impairment. PRIMARY OUTCOME: Suicidal ideation and suicide attempt in the past year. RESULTS: People with visual or hearing sensory impairments had twice the odds of past-year suicidal ideation (OR 2.06; 95% CI 1.17 to 2.73; p<0.001), and over three times the odds of reporting past-year suicide attempt (OR 3.12; 95% CI 1.57 to 6.20; p=0.001) compared with people without these impairments. Similar results were found for hearing and visual impairments separately and co-occurring. CONCLUSIONS: We found evidence that individuals with sensory impairments are more likely to have thought about or attempted suicide in the past year than individuals without

Application of an hybrid optimization approach in the design of long endurance airfoils

Future Re-Configurable Multi Mission Unmanned Aerial Vehicle (RC-MM-UAV) Design concepts are expected to comprise of morphing wings with mission segment based airfoils. The Direct Numerical Optimization (DNO) methodology for airfoil shape optimization is established. The PARSEC shape function is used for airfoil geometry parameterization, coupled with a low-fidelity solver and Particle Swarm Optimizer (PSO) in the design analysis of a long endurance airfoil. A single-point airfoil design study through the DNO approach was executed. Results indicate that the methodology is computationally demanding thus, Artificial Neural Networks (ANN) are introduced to address this issue. A relationship between PARSEC airfoil geometry variables as inputs and the equating aerodynamic coefficients as outputs are used in network training and validation. The effect of varying training sample size was evaluated to establish a network with acceptable generalization capabilities. The PSO model is integrated to the ANN model for airfoil design optimization. The hybrid PSO/ANN structure required 38% fewer solver calls in comparison to the direct search approach. The proposed hybrid methodology is applicable for future multi-point airfoil design optimizations
