Social Sector Business Ventures: The Critical Factors That Maximize Success

This paper seeks to help social sector leaders understand the factors that they should consider when launching revenue-generating business ventures. Given that much of the research on social sector business ventures is based on the personal experiences of individual practitioners, there is a wide array of advice for organizational leaders who are thinking about launching business ventures. Consequently, we approach the subject of social sector business ventures in a systematic and analytic way in order to determine what organizational leaders really need to know about launching successful ventures. We introduce a framework called "business in a box" that separates the process of thinking about launching business ventures from the organizational characteristics and dynamics that influence these ventures. We assert that organizational leaders who wish to maximize the success of their business ventures must explore (1) what is "inside" the box (The Business and its Context) to understand the business fundamentals of launching a venture and (2) what is "outside" the box (Assets and Internal Destructive Forces) to understand the forces and dynamics within the organizational context that impact these ventures.This publication is Hauser Center Working Paper No. 43.

Material response from Mach 0.3 burner rig combustion of a coal-oil mixture

Wedge shaped specimens were exposed to the combustion gases of a Mach 0.3 burner rig fueled with a mixture of 40 weight percent micron size coal particles dispersed in No. 2 fuel oil. Exposure temperature was about 900 C and the test duration was about 44 one hour cycles. The alloys tested were the nickel base superalloys, IN-100, U-700 and IN-792, and the cobalt base superalloy, Mar-M509. The deposits on the specimens were analyzed and the extent of corrosion/erosion was measured. The chemical compositions of the deposits were compared with the predictions from an equilibrium thermodynamic analysis. The experimental results were in very good agreement with the predictions

Combustion system processes leading to corrosive deposits

Degradation of turbine engine hot gas path components by high temperature corrosion can usually be associated with deposits even though other factors may also play a significant role. The origins of the corrosive deposits are traceable to chemical reactions which take place during the combustion process. In the case of hot corrosion/sulfidation, sodium sulfate was established as the deposited corrosive agent even when none of this salt enters the engine directly. The sodium sulfate is formed during the combustion and deposition processes from compounds of sulfur contained in the fuel as low level impurities and sodium compounds, such as sodium chloride, ingested with intake air. In other turbine and power generation situations, corrosive and/or fouling deposits can result from such metals as potassium, iron, calcium, vanadium, magnesium, and silicon

Absolute flux measurements for swift atoms

While a torsion balance in vacuum can easily measure the momentum transfer from a gas beam impinging on a surface attached to the balance, this measurement depends on the accommodation coefficients of the atoms with the surface and the distribution of the recoil. A torsion balance is described for making absolute flux measurements independent of recoil effects. The torsion balance is a conventional taut suspension wire design and the Young modulus of the wire determines the relationship between the displacement and the applied torque. A compensating magnetic field is applied to maintain zero displacement and provide critical damping. The unique feature is to couple the impinging gas beam to the torsion balance via a Wood's horn, i.e., a thin wall tube with a gradual 90 deg bend. Just as light is trapped in a Wood's horn by specular reflection from the curved surfaces, the gas beam diffuses through the tube. Instead of trapping the beam, the end of the tube is open so that the atoms exit the tube at 90 deg to their original direction. Therefore, all of the forward momentum of the gas beam is transferred to the torsion balance independent of the angle of reflection from the surfaces inside the tube

"My Home is an Asset Class": The Financialization of Housing in Europe

Over the past decades, institutional landlords – from real estate companies like the German giant Vonovia to private equity companies like Blackstone, or pension funds like ABP, the Dutch pension fund for government and education employees – have minted EUR 40bn of Berlin’s houses into assets that they rent out. This is roughly double the combined value of London’s and Amsterdam's institutionally owned houses and it is a trend that has accelerated since the COVID19 pandemic. Europe’s residential real estate has become an attractive asset class for investors worldwide, supported by a range of government policies that are ostensibly aimed at homeowners: support for housing markets pushes up house prices and reduces affordability for citizens, whereas income support for rent-paying households ensures stable returns for investors. In response, citizens across Europe – from Berlin to Dublin and Madrid – have mobilized to pressure governments into taking action. From rent controls to better regulation or even expropriation of institutional landlords, the political tide seems to be turning against a decades-old phenomenon known as the financialization of housing. A mega-trend across housing markets everywhere, it can be understood as (1) the disproportionate growth of housing finance relative to the underlying housing economy or (2) the turn to Housing as an Asset Class (HAC), captured by the increasing for-profit and financial orientation of actors in housing markets, and encouraged in Europe by a broad range of European-level financial legislation. In this report, we explore the growing importance of institutional landlords such as Blackstone, focusing in particular on the mechanisms through which European legislation has accommodated their strategies to transform housing into asset classes. We use data to map the complex financial ecosystem behind private equity landlords. We then propose a set of reforms that would de-financialize housing for the public good.1.

A Model for the Stray Light Contamination of the UVCS Instrument on SOHO

We present a detailed model of stray-light suppression in the spectrometer channels of the Ultraviolet Coronagraph Spectrometer (UVCS) on the SOHO spacecraft. The control of diffracted and scattered stray light from the bright solar disk is one of the most important tasks of a coronagraph. We compute the fractions of light that diffract past the UVCS external occulter and non-specularly pass into the spectrometer slit. The diffracted component of the stray light depends on the finite aperture of the primary mirror and on its figure. The amount of non-specular scattering depends mainly on the micro-roughness of the mirror. For reasonable choices of these quantities, the modeled stray-light fraction agrees well with measurements of stray light made both in the laboratory and during the UVCS mission. The models were constructed for the bright H I Lyman alpha emission line, but they are applicable to other spectral lines as well.Comment: 19 pages, 5 figures, Solar Physics, in pres

Thermochemical analyses of the oxidative vaporization of metals and oxides by oxygen molecules and atoms

Equilibrium thermochemical analyses are employed to describe the vaporization processes of metals and metal oxides upon exposure to molecular and atomic oxygen. Specific analytic results for the chromium-, platinum-, aluminum-, and silicon-oxygen systems are presented. Maximum rates of oxidative vaporization predicted from the thermochemical considerations are compared with experimental results for chromium and platinum. The oxidative vaporization rates of chromium and platinum are considerably enhanced by oxygen atoms

The effects of trace impurities in coal-derived liquid fuels on deposition and accelerated high temperature corrosion of cast superalloys

The effects of trace metal impurities in coal-derived liquids on deposition, high temperature corrosion and fouling were examined. Alloys were burner rig tested from 800 to 1100 C and corrosion was evaluated as a function of potential impurities. Actual and doped fuel test were used to define an empirical life prediction equation. An evaluation of inhibitors to reduce or eliminate accelerated corrosion was made. Barium and strontium were found to limit attack. Intermittent application of the inhibitors or silicon additions were found to be effective techniques for controlling deposition without losing the inhibitor benefits. A computer program was used to predict the dew points and compositions of deposits. These predictions were confirmed in deposition test. The potential for such deposits to plug cooling holes of turbine airfoils was evaluated. Tests indicated that, while a potential problem exists, it strongly depended on minor impurity variations

Electron Densities from Gas‐Phase Electron Diffraction Intensities. II. Molecular Hartree–Fock Cross Sections

Differential cross sections for electron scattering based on molecular Hartree–Fock electron densities are compared with cross sections based on the independent‐atom approximation for the molecules C2, N2, O2, F2, and CO. The results show that bonding effects on the electron density manifest themselves to the extent of several percent in the scattered intensity at small scattering angles. Furthermore, molecule‐to‐molecule variations in the shifts of electron density are clearly reflected in variations in the functional form of the scattered intensity. A comparison of the calculated intensities for N2 and O2 with preliminary experimental intensities suggests that electron scattering techniques now in development should be able to provide information about bonding and electron correlation effects competitive in accuracy with that of current quantum‐mechanical calculations.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70136/2/JCPSA6-51-7-2896-1.pd
