he U.S. Department of Housing and Urban Development’s (HUD) Moving to Opportunity for Fair Housing Demonstration, or MTO, is a large, federally funded social experiment designed to test whether improved neighborhood opportunities may significantly affect the life chances of lowincome public housing residents. This paper provides the first systematic overview of the design of the MTO and describ...

The lean manufacturing system has helped many companies to improve operational performance, mainly in the automotive and electronic supply chains. Although lean manufacturing revealed to be effective for repetitive systems, some small and medium suppliers, faced with high mix and low volume production, have had difficulty to implement the lean manufacturing. The main objective of this paper is ...

Although non-experimental studies find robust neighborhood effects on adults, such findings have been challenged by results from the Moving to Opportunity (MTO) residential mobility experiment. Using a within-study comparison design, this paper compares experimental and estimates MTO parallel analysis of Panel Study Income Dynamics (PSID). Striking similarities were found between based PSID. No...

A convenient and efficient application of microencapsulated/methylrhenium trioxide (MTO) and MTO/pyridine systems for the selective oxidation of cardanol derivatives is reported. Environmentally friendly and low-cost H2O2 was used as the oxygen atom donor. The catalysts were stable systems for at least five recycling experiments. In the oxidation of C2 alkyl-substituted cardanol derivatives, hi...

Moving to Opportunity (MTO) offered public housing residents the opportunity to move to low-poverty neighborhoods. Several years later, boys in the experimental group fared no better on measures of risk behavior than their control group counterparts, whereas girls in the experimental group engaged in lower-risk behavior than control group girls. The authors explore these differences by analyzin...

A novel and efficient procedure to prepare highly oxidised aryltetralin lignans, such as isopodophyllotoxone and (-)-aristologone derivatives, by oxidation of podophyllotoxin and galbulin with methylrhenium trioxide (MTO) and novel MTO heterogeneous catalysts is reported. It is noteworthy that in the case of isopodophyllotoxone derivatives the functionalisation of the C-4 position of the C-ring...

Formaldehyde (HCHO), generating from hydrogen transfer (HT) of reactant, is significant for autocatalysis initiation and deactivation in methanol-to-olefins (MTO), but hitherto, its evolution throughout the reaction has not been thoroughly revealed. Herein, by established colorimetric analysis method, HCHO MTO dimethyl ether (DME)-to-olefins (DTO) reactions over SAPO-34 was situ quantitatively ...

the thermodynamic of the known and very effective catalytic system, hydrogen peroxide (h2o2) and methyltrioxorhenium (mto) is studied in different solvents using uv-visible spectroscopic method. the thermodynamic parameters (δg, δh and δs) for two equilibrium reactions, mto + h2o2 ⇌ a + h2o and a + h2o2 ⇌ b.h2o (a, [mere(o)2(o2)]; b.h2o, [mere(oh2)(o)(o2)2]), are determined. the obtained free e...
