An orphanage is a residential institution, total institution or group home, devoted to the care of orphans and children who, for various reasons, cannot be cared for by their biological families. The parents may be deceased, absent, or abusive. There may be substance abuse or mental illness in the biological home, or the parent may simply be unwilling to care for the child. The legal responsibility for the support of abandoned children differs from country to country, and within countries. Government-run orphanages have been phased out in most developed countries during the latter half of the 20th century but continue to operate in many other regions internationally. It is now generally accepted that orphanages are detrimental to the emotional wellbeing of children, and government support goes instead towards supporting the family unit.
An orphan drug is a pharmaceutical agent that is developed to treat certain rare medical conditions. An orphan drug would not be profitable to produce without government assistance, due to the small population of patients affected by the conditions. The conditions that orphan drugs are used to treat are referred to as orphan diseases. The assignment of orphan status to a disease and to drugs developed to treat it is a matter of public policy that depends on the legislation of the country.
Campaign to Defend the Constitution (DefCon) was an American online organization founded in September 2005 to support the separation of church and state and to oppose what it perceived as the growing influence of the religious right. It was a project of the Tides Center, a non-profit organization that funds progressive groups. However, its funding ran out in November 2007, at which time its blog announced the organization was "taking a break."
Rev-Erb alpha (Rev-Erbɑ), also known as nuclear receptor subfamily 1 group D member 1 (NR1D1), is one of two Rev-Erb proteins in the nuclear receptor (NR) family of intracellular transcription factors. In humans, REV-ERBɑ is encoded by the NR1D1 gene, which is highly conserved across animal species.
RAR-related orphan receptor alpha (RORα), also known as NR1F1 is a nuclear receptor that in humans is encoded by the RORA gene. RORα participates in the transcriptional regulation of some genes involved in circadian rhythm. In mice, RORα is essential for development of cerebellum through direct regulation of genes expressed in Purkinje cells. It also plays an essential role in the development of type 2 innate lymphoid cells (ILC2) and mutant animals are ILC2 deficient. In addition, although present in normal numbers, the ILC3 and Th17 cells from RORα deficient mice are defective for cytokine production.
Rev-Erb beta (Rev-Erbβ), also known as nuclear receptor subfamily 1 group D member 2 (NR1D2), is a member of the Rev-Erb protein family. Rev-Erbβ, like Rev-Erbα, belongs to the nuclear receptor superfamily of transcription factors and can modulate gene expression through binding to gene promoters. Together with Rev-Erbα, Rev-Erbβ functions as a major regulator of the circadian clock. These two proteins are partially redundant. Current research suggests that Rev-Erbβ is less important in maintaining the circadian clock than Rev-Erbα; knock-out studies of Rev-Erbα result in significant circadian disruption but the same has not been found with Rev-Erbβ. Rev-Erbβ compensation for Rev-Erbα varies across tissues, and further research is needed to elucidate the separate role of Rev-Erbβ.
RAR-related orphan receptor gamma (RORγ) is a protein that in humans is encoded by the RORC gene. RORγ is a member of the nuclear receptor family of transcription factors. It is mainly expressed in immune cells and it also regulates circadian rhythms. It may be involved in the progression of certain types of cancer.
Return on investment (ROI) or return on costs (ROC) is the ratio between net income and investment. A high ROI means the investment's gains compare favourably to its cost. As a performance measure, ROI is used to evaluate the efficiency of an investment or to compare the efficiencies of several different investments. In economic terms, it is one way of relating profits to capital invested.
Orphanhood in Romania became prevalent as a consequence of the Socialist Republic of Romania's natalist policy under Nicolae Ceaușescu. Its effectiveness led to an increase in birth rates at the expense of adequate family planning and reproductive rights. Its consequences were most felt with the collapse of the regime's social safety net during the 1980's Romanian austerity period, which led to widespread institutional neglect of the needs of orphans, with severe consequences in their health, including high rates of HIV infection in children, and well-being. A series of international and governmental interventions have taken place since the 1990s to improve the conditions in orphanages and reform the country's child protection system.
Reaching Out Romania is a non-governmental charitable organization in Romania that helps girls ages 13 to 22 exit the sex industry. ROR rescues these girls from the Moldovan and Romanian mafia, which have normally trafficked the girls out of Romania and into Western Europe. ROR runs a facility in Pitești that offers life skills-based education to these girls, teaching them to do things such as painting and sewing. This safe house hides the girls from their traffickers. A psychologist is on staff to meet with the girls. The organization was founded in 1999 by Iana Matei, who was named European of the Year in 2010 by Reader's Digest.
