104-691: Carnegie Museums of Pittsburgh is a nonprofit organization that operates four museums in Pittsburgh , Pennsylvania , United States . The organization is headquartered in the Carnegie Institute and Library complex in the Oakland neighborhood of Pittsburgh. The Carnegie Institute complex, which includes the original museum, recital hall, and library, was added to the National Register of Historic Places on March 30, 1979. Two of
208-424: A delegate structure to allow for the representation of groups or corporations as members. Alternatively, it may be a non-membership organization and the board of directors may elect its own successors. The two major types of nonprofit organization are membership and board-only. A membership organization elects the board and has regular meetings and the power to amend the bylaws. A board-only organization typically has
312-425: A detergent agent (such as sodium dodecylbenzene sulfonate ). Plaster may also be used to create complex detailing for use in room interiors. These may be geometric (simulating wood or stone) or naturalistic (simulating leaves, vines, and flowers). These are also often used to simulate wood or stone detailing found in more substantial buildings. In modern days this material is also used for false ceiling . In this,
416-403: A fire. Early versions of protective plasters often contain asbestos fibres, which since have been outlawed in many industrialized nations. Recent plasters for fire protection either contain cement or gypsum as binding agents as well as mineral wool or glass fiber to add mechanical strength. Vermiculite , polystyrene beads or chemical expansion agents are often added to decrease the density of
520-554: A fiscally viable entity. Nonprofits have the responsibility of focusing on being professional and financially responsible, replacing self-interest and profit motive with mission motive. Though nonprofits are managed differently from for-profit businesses, they have felt pressure to be more businesslike. To combat private and public business growth in the public service industry, nonprofits have modeled their business management and mission, shifting their reason of existing to establish sustainability and growth. Setting effective missions
624-455: A hand-made and pleasing textured alternative to machine-made modern substrate finishes. But clay plaster finishes are rare and fleeting. According to Martin Weaver, "Many of North America's historic building interiors … are all too often … one of the first things to disappear in the frenzy of demolition of interiors which has unfortunately come to be a common companion to 'heritage preservation' in
728-400: A hidden supporting framework. Forms of plaster have several other uses. In medicine, plaster orthopedic casts are still often used for supporting set broken bones. In dentistry, plaster is used to make dental models by pouring the material into dental impressions . Various types of models and moulds are made with plaster. In art, lime plaster is the traditional matrix for fresco painting;
832-940: A history that dates to October 24, 1939, the Kamin Science Center is the most visited museum in Pittsburgh. The Kamin Science Center houses the Buhl Planetarium & Observatory, the Rangos Giant Cinema Theater, and a number of temporary and permanent exhibits, including Highmark SportsWorks , the Miniature Railroad & Village , and the Robot Hall of Fame . On February 21, 1990, Pennsylvania Senator John Heinz introduced Senate Bill S. 2151, which allowed
936-467: A lime and sand mortar to provide a weather proof seal to protect from water penetration. This allowed a rendering of clay plaster and setting coat of thin lime and fine sand on exterior-walled rooms. Split lath was nailed with square cut lath nails, one into each framing member. With hand split lath the plasterer had the luxury of making lath to fit the cavity being plastered. Lengths of lath two to six foot are not uncommon at Economy Village. Hand split lath
1040-471: A low-stress work environment that the employee can associate him or herself positively with. Other incentives that should be implemented are generous vacation allowances or flexible work hours. When selecting a domain name , NPOs often use one of the following: .org , the country code top-level domain of their respective country, or the .edu top-level domain (TLD), to differentiate themselves from more commercial entities, which typically use .com . In
1144-401: A material used for the interiors of buildings, while "render" commonly refers to external applications. The term stucco refers to plasterwork that is worked in some way to produce relief decoration, rather than flat surfaces. The most common types of plaster mainly contain either gypsum , lime , or cement , but all work in a similar way. The plaster is manufactured as a dry powder and
SECTION 10
#17327659443181248-622: A mixture of suitable plaster, sand, Portland cement and water which is normally applied to masonry interiors and exteriors to achieve a smooth surface. Interior surfaces sometimes receive a final layer of gypsum plaster. Walls constructed with stock bricks are normally plastered while face brick walls are not plastered. Various cement-based plasters are also used as proprietary spray fireproofing products. These usually use vermiculite as lightweight aggregate. Heavy versions of such plasters are also in use for exterior fireproofing, to protect LPG vessels, pipe bridges and vessel skirts. Cement plaster
1352-457: A nonprofit entity without having tax-exempt status. Key aspects of nonprofits are accountability, integrity, trustworthiness, honesty, and openness to every person who has invested time, money, and faith into the organisation. Nonprofit organizations are accountable to the donors, founders, volunteers, program recipients, and the public community. Theoretically, for a nonprofit that seeks to finance its operations through donations, public confidence
1456-471: A patient's head and neck, and liquid plaster is used to fill the impression and produce a plaster bust. The transparent material polymethyl methacrylate (Plexiglas, Perspex) is then vacuum formed over this bust to create a clear face mask which will hold the patient's head steady while radiation is being delivered. In dentistry, plaster is used for mounting casts or models of oral tissues. These diagnostic and working models are usually made from dental stone,
1560-454: A plaster positive was desired this would be constructed or cast to form a durable image artwork. As a model for stonecutters this would be sufficient. If intended for producing a bronze casting the plaster positive could be further worked to produce smooth surfaces. An advantage of this plaster image is that it is relatively cheap; should a patron approve of the durable image and be willing to bear further expense, subsequent molds could be made for
1664-410: A plaster secondary support. Some, like Michelangelo's Sistine Chapel ceiling , are executed in fresco , meaning they are painted on a thin layer of wet plaster, called intonaco ; the pigments sink into this layer so that the plaster itself becomes the medium holding them, which accounts for the excellent durability of fresco. Additional work may be added a secco on top of the dry plaster, though this
1768-407: A positive model of the limb and used in fabricating the final medical device. In addition, dentures (false teeth) are made by first taking a dental impression using a soft, pliable material that can be removed from around the teeth and gums without loss of fidelity and using the impression to creating a wax model of the teeth and gums. The model is used to create a plaster mold (which is heated so
1872-400: A primary advantage of the material is that it is resistant to a fire within a room and so can assist in reducing or eliminating structural damage or destruction provided the fire is promptly extinguished. Lime plaster is used for frescoes , where pigments , diluted in water, are applied to the still wet plaster. USA and Iran are the main plaster producers in the world. Cement plaster is
1976-420: A remarkable property of setting into a hard mass on wetting with water. CaSO 4 ⋅ 1 2 H 2 O + 1 1 2 H 2 O ⟶ CaSO 4 ⋅ 2 H 2 O {\displaystyle {\ce {CaSO4.1/2H2O + 1 1/2H2O -> CaSO4.2H2O}}} Plaster of Paris
2080-431: A rigid denture base. Moreover, in dentistry there are 5 types of gypsum products depending on their consistency and uses: 1) impression plaster (type 1), 2) model plaster (type 2), dental stones (types 3, 4 and 5) In orthotics and prosthetics, plaster bandages traditionally were used to create impressions of the patient's limb (or residuum). This negative impression was then, itself, filled with plaster of Paris, to create
2184-697: A self-selected board and a membership whose powers are limited to those delegated to it by the board. A board-only organization's bylaws may even state that the organization does not have any membership, although the organization's literature may refer to its donors or service recipients as 'members'; examples of such organizations are FairVote and the National Organization for the Reform of Marijuana Laws . The Model Nonprofit Corporation Act imposes many complexities and requirements on membership decision-making. Accordingly, many organizations, such as

#17327659443182288-523: A sledge. When small enough, a froe and mallet were used to split away narrow strips of lath. Farm animals provided hair and manure for the float coat of plaster. Fields of wheat and grains provided straw and hay to reinforce the clay plaster. But there was no uniformity in clay plaster recipes. Manure provides fiber for tensile strength as well as protein adhesive. Unlike casein used with lime plaster, hydrogen bonds of manure proteins are weakened by moisture. With braced timber-framed structures clay plaster
2392-471: A strong vision of how to operate the project, try to retain control of the organization, even as new employees or volunteers want to expand the project's scope or change policy. Resource mismanagement is a particular problem with NPOs because the employees are not accountable to anyone who has a direct stake in the organization. For example, an employee may start a new program without disclosing its complete liabilities. The employee may be rewarded for improving
2496-416: A stronger, harder and denser derivative of plaster which is manufactured from gypsum under pressure. Plaster is also used to invest and flask wax dentures, the wax being subsequently removed by "burning out," and replaced with flowable denture base material. The typically acrylic denture base then cures in the plaster investment mold. Plaster investments can withstand the high heat and pressure needed to ensure
2600-581: A wide diversity of structures and purposes. For legal classification, there are, nevertheless, some elements of importance: Some of the above must be (in most jurisdictions in the US at least) expressed in the organization's charter of establishment or constitution. Others may be provided by the supervising authority at each particular jurisdiction. While affiliations will not affect a legal status, they may be taken into consideration by legal proceedings as an indication of purpose. Most countries have laws that regulate
2704-399: Is a factor in the amount of money that a nonprofit organization is able to raise. Supposedly, the more a nonprofit focuses on their mission, the more public confidence they will gain. This will result in more money for the organization. The activities a nonprofit is partaking in can help build the public's confidence in nonprofits, as well as how ethical the standards and practices are. There
2808-461: Is a key for the successful management of nonprofit organizations. There are three important conditions for effective mission: opportunity, competence, and commitment. One way of managing the sustainability of nonprofit organizations is to establish strong relations with donor groups. This requires a donor marketing strategy, something many nonprofits lack. Nonprofit organizations provide public goods that are undersupplied by government. NPOs have
2912-590: Is a mixture of clay , sand and water often with the addition of plant fibers for tensile strength over wood lath . Clay plaster has been used around the world at least since antiquity. Settlers in the American colonies used clay plaster on the interiors of their houses: "Interior plastering in the form of clay antedated even the building of houses of frame, and must have been visible in the inside of wattle filling in those earliest frame houses in which … wainscot had not been indulged. Clay continued in use long after
3016-462: Is accompanied by a slight expansion of volume. It is used in making casts for statues, toys , and more. The initial matrix consists mostly of orthorhombic crystals: the kinetic product. Over the next 72 hours, the rhombic crystals give way to an interlocking mass of monoclinic crystal needles, and the plaster increases in hardness and strength. If plaster or gypsum is heated to between 130 °C (266 °F) and 180 °C (350 °F), hemihydrate
3120-439: Is an important distinction in the US between non-profit and not-for-profit organizations (NFPOs); while an NFPO does not profit its owners, and money goes into running the organization, it is not required to operate for the public good. An example is a club, whose purpose is its members' enjoyment. Other examples of NFPOs include: credit unions, sports clubs, and advocacy groups. Nonprofit organizations provide services to
3224-414: Is an important distinction in the US between non-profit and not-for-profit organizations (NFPOs); while an NFPO does not profit its owners, and money goes into running the organization, it is not required to operate for the public good. An example is a sports club, whose purpose is its members' enjoyment. The names used and precise regulations vary from one jurisdiction to another. According to

3328-525: Is commonly based on the reaction of gypsum plaster with water, where the water is selectively applied by the inkjet head. The chemical reaction that occurs when plaster is mixed with water is exothermic . When plaster sets, it can reach temperatures of more than 60 °C (140 °F) and, in large volumes, can burn the skin. In January 2007, a secondary school student in Lincolnshire , England sustained third-degree burns after encasing her hands in
3432-557: Is concerned. In many countries, nonprofits may apply for tax-exempt status, so that the organization itself may be exempt from income tax and other taxes. In the United States, to be exempt from federal income taxes, the organization must meet the requirements set forth in the Internal Revenue Code (IRC). Granting nonprofit status is done by the state, while granting tax-exempt designation (such as IRC 501(c) )
3536-456: Is formed, which will also re-form as gypsum if mixed with water. On heating to 180 °C (350 °F), the nearly water-free form, called γ-anhydrite (CaSO 4 · n H 2 O where n = 0 to 0.05) is produced. γ-anhydrite reacts slowly with water to return to the dihydrate state, a property exploited in some commercial desiccants . On heating above 250 °C (480 °F), the completely anhydrous form called β-anhydrite or dead burned plaster
3640-436: Is formed. Lime plaster is a mixture of calcium hydroxide and sand (or other inert fillers). Carbon dioxide in the atmosphere causes the plaster to set by transforming the calcium hydroxide into calcium carbonate ( limestone ). Whitewash is based on the same chemistry. To make lime plaster, limestone (calcium carbonate) is heated above approximately 850 °C (1600 °F) to produce quicklime (calcium oxide). Water
3744-735: Is generally less durable. Plaster (often called stucco in this context) is a far easier material for making reliefs than stone or wood, and was widely used for large interior wall-reliefs in Egypt and the Near East from antiquity into Islamic times (latterly for architectural decoration, as at the Alhambra ), Rome, and Europe from at least the Renaissance, as well as probably elsewhere. However, it needs very good conditions to survive long in unmaintained buildings – Roman decorative plasterwork
3848-453: Is granted by the federal government via the IRS. This means that not all nonprofits are eligible to be tax-exempt. For example, employees of non-profit organizations pay taxes from their salaries, which they receive according to the laws of the country. NPOs use the model of a double bottom line in that furthering their cause is more important than making a profit, though both are needed to ensure
3952-490: Is mainly known from Pompeii and other sites buried by ash from Mount Vesuvius . Plaster may be cast directly into a damp clay mold. In creating this piece molds (molds designed for making multiple copies) or waste molds (for single use) would be made of plaster. This "negative" image, if properly designed, may be used to produce clay productions, which when fired in a kiln become terra cotta building decorations, or these may be used to create cast concrete sculptures. If
4056-500: Is mixed with water to form a stiff but workable paste immediately before it is applied to the surface. The reaction with water liberates heat through crystallization and the hydrated plaster then hardens. Plaster can be relatively easily worked with metal tools and sandpaper and can be moulded, either on site or in advance, and worked pieces can be put in place with adhesive . Plaster is suitable for finishing rather than load-bearing, and when thickly applied for decoration may require
4160-408: Is not classifiable as another category. Currently, no restrictions are enforced on registration of .com or .org, so one can find organizations of all sorts in either of those domains, as well as other top-level domains including newer, more specific ones which may apply to particular sorts of organization including .museum for museums and .coop for cooperatives . Organizations might also register by
4264-477: Is not uniform like sawn lath. The straightness or waviness of the grain affected the thickness or width of each lath, and thus the spacing of the lath. The clay plaster rough coat varied to cover the irregular lath. Window and door trim as well as the mudboard (baseboard) acted as screeds. With the variation of the lath thickness and use of coarse straw and manure, the clay coat of plaster was thick in comparison to later lime-only and gypsum plasters. In Economy Village,

4368-594: Is often used as an artistic material for casting. Plaster is also commonly spread over an armature (form), made of wire mesh, cloth, or other materials; a process for adding raised details. For these processes, limestone or acrylic based plaster may be employed, known as stucco. Products composed mainly of plaster of Paris and a small amount of Portland cement are used for casting sculptures and other art objects as well as molds. Considerably harder and stronger than straight plaster of Paris, these products are for indoor use only as they degrade in moist conditions. Plaster
4472-533: Is produced by heating gypsum to about 120–180 °C (248–356 °F) in a kiln: CaSO 4 ⋅ 2 H 2 O ⟶ heat CaSO 4 ⋅ 1 2 H 2 O + 1 1 2 H 2 O ↑ {\displaystyle {\ce {CaSO4.2H2O {\overset {heat}{{}->{}}}{CaSO4.1/2H2O}+ 1\!1/2 H2O ^}}} (released as steam). Plaster of Paris has
4576-419: Is stored in moisture -proof containers, because the presence of moisture can cause slow setting of plaster of Paris by bringing about its hydration, which will make it useless after some time. When the dry plaster powder is mixed with water, it rehydrates over time into gypsum. The setting of plaster slurry starts about 10 minutes after mixing and is complete in about 45 minutes. The setting of plaster of Paris
4680-605: Is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. Depending on the local laws, charities are regularly organized as non-profits. A host of organizations may be nonprofit, including some political organizations, schools, hospitals, business associations, churches, foundations, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be tax-exempt , and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as
4784-411: Is the remuneration package, though many who have been questioned after leaving an NPO have reported that it was stressful work environments and the workload. Public- and private-sector employment have, for the most part, been able to offer more to their employees than most nonprofit agencies throughout history. Either in the form of higher wages, more comprehensive benefit packages, or less tedious work,
4888-421: Is then added to produce slaked lime (calcium hydroxide), which is sold as a wet putty or a white powder. Additional water is added to form a paste prior to use. The paste may be stored in airtight containers. When exposed to the atmosphere, the calcium hydroxide very slowly turns back into calcium carbonate through reaction with atmospheric carbon dioxide, causing the plaster to increase in strength. Lime plaster
4992-476: Is to find lime, bricks, clay, stone, haire, together with laborers and workmen." Records of the New Haven colony in 1641 mention clay and hay as well as lime and hair also. In German houses of Pennsylvania the use of clay persisted. Old Economy Village is one such German settlement. The early Nineteenth-Century utopian village in present-day Ambridge , Pennsylvania, used clay plaster substrate exclusively in
5096-400: Is to replace conventional gypsum plasters in cases where the temperature can get too high for gypsum plaster to stay on the wall or ceiling. An example of a heat-resistant plaster composition is a mixture of Portland cement , gypsum, lime, exfoliated insulating aggregate ( perlite and vermiculite or mica ), phosphate shale , and small amounts of adhesive binder (such as Gum karaya ), and
5200-476: Is unique in which source of income works best for them. With an increase in NPOs since 2010, organizations have adopted competitive advantages to create revenue for themselves to remain financially stable. Donations from private individuals or organizations can change each year and government grants have diminished. With changes in funding from year to year, many nonprofit organizations have been moving toward increasing
5304-503: Is used. The walls are painted with the plaster which (in some countries) is nothing but calcium carbonate. After drying the calcium carbonate plaster turns white and then the wall is ready to be painted. Elsewhere in the world, such as the UK, ever finer layers of plaster are added on top of the plasterboard (or sometimes the brick wall directly) to give a smooth brown polished texture ready for painting. Mural paintings are commonly painted onto

Plaster is also used in preparation for radiotherapy when fabricating individualized immobilization shells for patients. Plaster bandages are used to construct an impression of
5512-769: The Kamin Science Center , are located in separate facilities on Pittsburgh's North Shore . Opened on May 15, 1994, the Andy Warhol Museum is the first museum to exclusively focus on an American postwar artist. The building which houses the Andy Warhol Museum was originally built in 1911 for industrial purposes, but was redesigned for the museum by architect Richard Gluckman . The museum currently has seven floors of gallery and exhibition space as well as an underground education studio and conservation lab. Warhol's primary artistic technique
5616-474: The Middle East at least 7,000 years ago. In Egypt, gypsum was burned in open fires, crushed into powder, and mixed with water to create plaster, used as a mortar between the blocks of pyramids and to provide a smooth wall facing. In Jericho, a cult arose where human skulls were decorated with plaster and painted to appear lifelike. The Romans brought plaster-work techniques to Europe . Clay plaster
5720-729: The National Center for Charitable Statistics (NCCS), there are more than 1.5 million nonprofit organizations registered in the United States , including public charities , private foundations , and other nonprofit organizations. Private charitable contributions increased for the fourth consecutive year in 2017 (since 2014), at an estimated $ 410.02 billion. Out of these contributions, religious organizations received 30.9%, education organizations received 14.3%, and human services organizations received 12.1%. Between September 2010 and September 2014, approximately 25.3% of Americans over

The purpose of the exhibit is for visitors to learn how people lived and worked on the boat. The Buhl Planetarium and larger Carnegie Museums of Pittsburgh merged in 1987, leading to an October 1989 groundbreaking on the newly-named Carnegie Science Center building. A large donation by the Kamin family led to

The National Association of Parliamentarians has generated concerns about the implications of this trend for the future of openness, accountability, and understanding of public concerns in nonprofit organizations. Specifically, they note that nonprofit organizations, unlike business corporations, are not subject to market discipline for products and shareholder discipline of their capital; therefore, without membership control of major decisions such as

In 2001 the museum acquired the archive of African-American photographer Charles "Teenie" Harris , consisting of approximately 80,000 photographic negatives spanning from the 1930s to the 1970s. Many of these images have been cataloged and digitized. The museum's permanent collection includes European and American decorative arts from the late seventeenth century to

It also houses the Carnegie Music Hall and the main branch of the Carnegie Library of Pittsburgh . Andrew Carnegie donated
6240-455: The NPO's reputation, making other employees happy, and attracting new donors. Liabilities promised on the full faith and credit of the organization but not recorded anywhere constitute accounting fraud . But even indirect liabilities negatively affect the financial sustainability of the NPO, and the NPO will have financial problems unless strict controls are instated. Some commenters have argued that
6344-443: The adoption of laths and brick filling for the frame." Where lime was not easily accessible it was rationed and usually substituted with clay as a binder. In Martin E. Weaver 's seminal work he says, "Mud plaster consists of clay or earth which is mixed with water to give a 'plastic' or workable consistency. If the clay mixture is too plastic it will shrink, crack and distort on drying. Sand, fine gravels and fibres were added to reduce

#17327659443186448-461: The age of 16 volunteered for a nonprofit. In the United States, both nonprofit organizations and not-for-profit organizations are tax-exempt. There are various types of nonprofit exemptions, such as 501(c)(3) organizations that are a religious, charitable, or educational-based organization that does not influence state and federal legislation, and 501(c)(7) organizations that are for pleasure, recreation, or another nonprofit purpose. There
6552-649: The appropriate country code top-level domain for their country. In 2020, nonprofit organizations began using microvlogging (brief videos with short text formats) on TikTok to reach Gen Z, engage with community stakeholders, and overall build community. TikTok allowed for innovative engagement between nonprofit organizations and younger generations. During COVID-19, TikTok was specifically used to connect rather than inform or fundraise, as its fast-paced, tailored For You Page separates itself from other social media apps such as Facebook and Twitter. Some organizations offer new, positive-sounding alternative terminology to describe
6656-401: The best of the newly minted workforce. It has been mentioned that most nonprofits will never be able to match the pay of the private sector and therefore should focus their attention on benefits packages, incentives and implementing pleasurable work environments. A good environment is ranked higher than salary and pressure of work. NPOs are encouraged to pay as much as they are able and offer

The use of clay in plaster and in laying brickwork appears to have been a common practice at that time not just in the construction of Economy village when the settlement was founded in 1824. Specifications for
6864-565: The community; for example aid and development programs, medical research, education, and health services. It is possible for a nonprofit to be both member-serving and community-serving. Nonprofit organizations are not driven by generating profit, but they must bring in enough income to pursue their social goals. Nonprofits are able to raise money in different ways. This includes income from donations from individual donors or foundations; sponsorship from corporations; government funding; programs, services or merchandise sales, and investments. Each NPO
6968-475: The concentrations of fine clay particles which were the cause of the excessive shrinkage." Manure was often added for its fibre content. In some building techniques straw or grass was used as reinforcement. In the Earliest European settlers' plasterwork, a mud plaster was used McKee wrote, of a circa 1675 Massachusetts contract that specified the plasterer, "Is to lath and siele the four rooms of

The choice of clay was because of its low cost, but also the availability. At Economy, root cellars dug under the houses yielded clay and sand (stone), or
7176-445: The creation of a wax image to be used in lost wax casting , a far more expensive process. In lieu of producing a bronze image suitable for outdoor use the plaster image may be painted to resemble a metal image; such sculptures are suitable only for presentation in a weather-protected environment. Plaster expands while hardening then contracts slightly just before hardening completely. This makes plaster excellent for use in molds, and it
7280-402: The diversity of their funding sources. For example, many nonprofits that have relied on government grants have started fundraising efforts to appeal to individual donors. Most nonprofits have staff that work for the company, possibly using volunteers to perform the nonprofit's services under the direction of the paid staff. Nonprofits must be careful to balance the salaries paid to staff against
7384-432: The election of the board, there are few inherent safeguards against abuse. A rebuttal to this might be that as nonprofit organizations grow and seek larger donations, the degree of scrutiny increases, including expectations of audited financial statements. A further rebuttal might be that NPOs are constrained, by their choice of legal structure, from financial benefit as far as distribution of profit to members and directors
7488-464: The entire Andy Warhol Video Collection, 228 four-minute Screen Tests , and 45 other films by Warhol; and extensive archives, including Warhol's Time Capsules . While dedicated to Andy Warhol, the museum also hosts many exhibits by contemporary artists. When Andrew Carnegie envisioned a museum collection consisting of the "Old Masters of tomorrow," the Carnegie Museum of Art arguably became
7592-475: The establishment and management of NPOs and that require compliance with corporate governance regimes. Most larger organizations are required to publish their financial reports detailing their income and expenditure publicly. In many aspects, they are similar to corporate business entities though there are often significant differences. Both not-for-profit and for-profit corporate entities must have board members, steering-committee members, or trustees who owe
7696-639: The finished product and increase thermal insulation. One differentiates between interior and exterior fireproofing. Interior products are typically less substantial, with lower densities and lower cost. Exterior products have to withstand harsher environmental conditions. A rough surface is typically forgiven inside of buildings as dropped ceilings often hide them. Fireproofing plasters are losing ground to more costly intumescent and endothermic products, simply on technical merit. Trade jurisdiction on unionized construction sites in North America remains with
7800-908: The first museum of modern art in the United States. The museum was founded as the Department of Fine Arts, Carnegie Institute in 1895. The name was changed to its current name in 1986. Today the museum continues showcasing contemporary art by staging the Carnegie International exhibition every three to five years. Numerous works from the International exhibitions have been acquired for the museums' permanent collection including Winslow Homer 's The Wreck (1896) and James A. McNeill Whistler 's Arrangement in Black: Portrait of Señor Pablo de Sarasate (1884). The Hall of Sculpture, constructed in white marble , replicates

8112-594: The interior of the Parthenon . The Hall of Architecture contains the largest collection of plaster casts of architectural masterpieces in America and one of the three largest in the world. Opened in 1974, the Sarah Scaife Galleries Annex was designed by Edward Larrabee Barnes and Associates. The Sarah Scaife Foundation gift nearly doubled the exhibition square footage. The modernist addition
8216-414: The library and the buildings. With the goal of inspiring people to do good for themselves and their communities, the terms for donations required communities to support them in exchange for the building and initial investment by Carnegie. The words "free to the people" inscribed above the entrance of the Carnegie Library of Pittsburgh illustrate his vision. The other two museums, The Andy Warhol Museum and
8320-489: The lime top coats are thin veneers often an eighth inch or less attesting to the scarcity of limestone supplies there. Clay plasters with their lack of tensile and compressive strength fell out of favor as industrial mining and technology advances in kiln production led to the exclusive use of lime and then gypsum in plaster applications. However, clay plasters still exist after hundreds of years clinging to split lath on rusty square nails. The wall variations and roughness reveal
8424-480: The mix. Because plaster of Paris sets quickly, "retardants" were used to slow setting time enough to allow workers to mix large working quantities of lime putty plaster. A modern form of this method uses expanded metal mesh over wood or metal structures, which allows a great freedom of design as it is adaptable to both simple and compound curves. Today this building method has been partly replaced with drywall , also composed mostly of gypsum plaster. In both these methods,
8528-511: The money paid to provide services to the nonprofit's beneficiaries. Organizations whose salary expenses are too high relative to their program expenses may face regulatory scrutiny. A second misconception is that nonprofit organizations may not make a profit. Although the goal of nonprofits is not specifically to maximize profits, they still have to operate as a fiscally responsible business. They must manage their income (both grants and donations and income from services) and expenses so as to remain
8632-564: The most complete Tyrannosaurus rex known to date—as well as exhibits such as Hillman Hall of Minerals and Gems , Alcoa Foundation Hall of American Indians, and Walton Hall of Ancient Egypt. The museum's Powdermill Nature Reserve was established in 1956 to serve as a field station for long-term studies of natural populations, and now forms the core of the museum's Center for Biodiversity and Ecosystems. Research teams that included Carnegie scientists have made discoveries such as Puijila darwini and Hadrocodium wui . Opened in 1991, but with
8736-403: The nearby Ohio river yielded washed sand from the sand bars; and lime outcroppings and oyster shell for the lime kiln . The surrounding forests of the new village of Economy provided straight grain, old- growth oak trees for lath. Hand split lath starts with a log of straight grained wood of the required length. The log is split into quarters and then smaller and smaller bolts with wedges and
8840-445: The nonprofit sector today regarding newly graduated workers, and to some, NPOs have for too long relegated hiring to a secondary priority, which could be why they find themselves in the position many do. While many established NPOs are well-funded and comparative to their public sector competitors, many more are independent and must be creative with which incentives they use to attract and maintain people. The initial interest for many
8944-411: The organization a fiduciary duty of loyalty and trust. A notable exception to this involves churches , which are often not required to disclose finances to anyone, including church members. In the United States, nonprofit organizations are formed by filing bylaws, articles of incorporation , or both in the state in which they expect to operate. The act of incorporation creates a legal entity enabling
9048-452: The organization to be treated as a distinct body (corporation) by law and to enter into business dealings, form contracts, and own property as individuals or for-profit corporations can. Nonprofits can have members, but many do not. The nonprofit may also be a trust or association of members. The organization may be controlled by its members who elect the board of directors , board of governors or board of trustees . A nonprofit may have
9152-463: The organization's sustainability. An advantage of nonprofits registered in the UK is that they benefit from some reliefs and exemptions. Charities and nonprofits are exempt from Corporation Tax as well as the trustees being exempt from Income Tax. There may also be tax relief available for charitable giving, via Gift Aid, monetary donations, and legacies. Founder's syndrome is an issue organizations experience as they expand. Dynamic founders, who have
9256-413: The pigments are applied to a thin wet top layer of plaster and fuse with it so that the painting is actually in coloured plaster. In the ancient world, as well as the sort of ornamental designs in plaster relief that are still used, plaster was also widely used to create large figurative reliefs for walls, though few of these have survived. Plaster was first used as a building material and for decoration in
9360-403: The plasterers, regardless of whether the plaster is decorative in nature or is used in passive fire protection. Cementitious and gypsum based plasters tend to be endothermic. Fireproofing plasters are closely related to firestop mortars. Most firestop mortars can be sprayed and tooled very well, due to the fine detail work that is required of firestopping. Powder bed and inkjet head 3D printing
9464-453: The powder form is converted in a sheet form and the sheet is then attached to the basic ceiling with the help of fasteners. It is done in various designs containing various combinations of lights and colors. The common use of this plaster can be seen in the construction of houses. Post-construction, direct painting is possible (which is commonly seen in French architecture), but elsewhere plaster
9568-447: The present, works on paper, paintings, prints (most notably Japanese prints), sculptures and installations. Opened alongside the Carnegie Museum of Art in 1895, the Carnegie Museum of Natural History is currently home to over twenty million objects and artifacts. Carnegie oversaw the collecting from 1895 to 1907 and it reflected his ideas of evolutionary development. Most notably, it houses a collection of 230 dinosaur fossils—including
9672-550: The public and private sectors have enjoyed an advantage over NPOs in attracting employees. Traditionally, the NPO has attracted mission-driven individuals who want to assist their chosen cause. Compounding the issue is that some NPOs do not operate in a manner similar to most businesses, or only seasonally. This leads many young and driven employees to forego NPOs in favor of more stable employment. Today, however, nonprofit organizations are adopting methods used by their competitors and finding new means to retain their employees and attract
9776-483: The receipt of significant funding from large for-profit corporations can ultimately alter the NPO's functions. A frequent measure of an NPO's efficiency is its expense ratio (i.e. expenditures on things other than its programs, divided by its total expenditures). Competition for employees with the public and private sector is another problem that nonprofit organizations inevitably face, particularly for management positions. There are reports of major talent shortages in
9880-408: The science center's renaming in 2024. Nonprofit organization A nonprofit organization ( NPO ), also known as a nonbusiness entity , nonprofit institution , or simply a nonprofit , is a legal entity organized and operated for a collective, public or social benefit, as opposed to an entity that operates as a business aiming to generate a profit for its owners. A nonprofit organization
9984-504: The sector in its own terms, without relying on terminology used for the government or business sectors. However, use of terminology by a nonprofit of self-descriptive language that is not legally compliant risks confusing the public about nonprofit abilities, capabilities, and limitations. Plaster Plaster is a building material used for the protective or decorative coating of walls and ceilings and for moulding and casting decorative elements. In English, "plaster" usually means
10088-570: The sector. The term civil society organization (CSO) has been used by a growing number of organizations, including the Center for the Study of Global Governance . The term citizen sector organization (CSO) has also been advocated to describe the sector – as one of citizens, for citizens – by organizations including Ashoka: Innovators for the Public . Advocates argue that these terms describe
10192-489: The traditional domain noted in RFC 1591 , .org is for "organizations that didn't fit anywhere else" in the naming system, which implies that it is the proper category for non-commercial organizations if they are not governmental, educational, or one of the other types with a specific TLD. It is not designated specifically for charitable organizations or any specific organizational or tax-law status, but encompasses anything that
10296-582: The wax melts and flows out) and the denture materials are injected into the mold. After a curing period, the mold is opened and the dentures are cleaned up and polished. Plasters have been in use in passive fire protection , as fireproofing products, for many decades. Gypsum plaster releases water vapor when exposed to flame, acting to slow the spread of the fire, for as much as an hour or two depending on thickness. Plaster also provides some insulation to retard heat flow into structural steel elements, that would otherwise lose their strength and collapse in
10400-431: Was a common building material for wall surfaces in a process known as lath and plaster , whereby a series of wooden strips on a studwork frame was covered with a semi-dry plaster that hardened into a surface. The plaster used in most lath and plaster construction was mainly lime plaster , with a cure time of about a month. To stabilize the lime plaster during curing, small amounts of plaster of Paris were incorporated into
10504-475: Was designed to not compete with the existing building. Trustee James L. Winokur says of architect Edward Larrabee Barnes, "He kept the old building out front. He was not terribly concerned about getting credit, just concerned about doing the job right, and he did do it right." The Heinz Architectural Center , opened as part of the museum in 1993, is dedicated to the collection, study, and exhibition of architectural drawings, prints and models. Most of these are from
10608-409: Was first introduced in America around 1909 and was often called by the generic name adamant plaster after a prominent manufacturer of the time. The advantages of cement plaster noted at that time were its strength, hardness, quick setting time and durability. Heat-resistant plaster is a building material used for coating walls and chimney breasts and for use as a fire barrier in ceilings. Its purpose
10712-599: Was silkscreen pop art, which he gained notoriety for in the early 1960s. The serial images derived from the culture's consumerism and conception of beauty are reified in a form of art which represent the identity of constituents in postwar American society. Images used by Warhol, which have made him famous for his contributions to pop art , include celebrities and consumables such as Marilyn Monroe and The Campbell's soup can . The museum's collection includes over 4,000 Warhol art works in all media — paintings , drawings , prints , photographs , sculptures , and installation ;
10816-424: Was used on interior walls and ceilings as well as exterior walls as the wall cavity and exterior cladding isolated the clay plaster from moisture penetration. Application of clay plaster in brick structures risked water penetration from failed mortar joints on the exterior brick walls. In Economy Village, the rear and middle wythes of brick dwelling walls are laid in a clay and sand mortar with the front wythe bedded in
