Satire | LEAD, n. A heavy blue-gray metal much used in giving stability to light lovers -- particularly to those who love not wisely but other men's wives. Lead is also of great service as a counterpoise to an argument of such weight that it turns the scale of debate the wrong way. An interesting fact in the chemistry of international controversy is that at the point of contact of two patriotisms lead is precipitated in great quantities. Hail, holy Lead! -- of human feuds the great And universal arbiter; endowed With penetration to pierce any cloud Fogging the field of controversial hate, And with a sift, inevitable, straight, Searching precision find the unavowed But vital point. Thy judgment, when allowed By the chirurgeon, settles the debate. O useful metal! -- were it not for thee We'd grapple one another's ears alway: But when we hear thee buzzing like a bee We, like old Muhlenberg, "care not to stay." And when the quick have run away like pellets Jack Satan smelts the dead to make new bullets. Source: Devil's Dictionary. |

Lead is a chemical element in the periodic table that has the symbol Pb and atomic number 82. A soft, heavy, toxic and malleable true metal, lead has a dull gray appearance and is bluish white when freshly cut but tarnishes to dull gray when exposed to air. Lead is used in building construction, lead-acid accumulators, bullets and shot, and is part of solder, pewter, and fusible alloys. Lead is the heaviest stable element.

Lead has a bright luster and is a ductile, very soft, highly malleable, bluish-white metal that has poor electrical conductivity. This true metal is highly resistant to corrosion. Becuse of this property, it is used to contain corrosive liquids (e.g. sulfuric acid). Lead can be toughened by adding a small amount of antimony or other metals to it.Applications
Early uses of lead included building materials, pigments for glazing ceramics, and pipes for transporting water. The castles and cathedrals of Europe contain considerable quantities of lead in decorative fixtures, roofs, pipes, and windows. Lead is the fifth most widely used metal (in its elemental state) after iron, aluminium, copper and zinc. Common uses include:Lead is a superconductor with critical temperature Tc=7.20 K (-265.95 °C).
- in lead-acid batteries, in electronic components, cable sheathing, ammunition, in the glass of CRTs, ceramics, leaded glass (see glass making), lead piping (not much used these days, although leaded solder was legal for use on drinking water pipes into the 1980s (US)), in paint (banned since 1978 in the US, and gradually in the UK from the 1950s to the 1970s, although older painted surfaces could be up to 50% lead by weight), casting alloys, pewter, solder, and dentistry filling. Also used as flashing on roofing to protect joins from rain. In gasoline (petrol) as tetra-ethyl lead and tetra-methyl lead to reduce knocking (also called pre-detonation, pre-ignition or pinking) from the 1920s, in 1986 leaded gasoline was banned from sale in the United States, in the EU in 1999.
History
Lead has been used by humans for at least 7000 years, because it was (and continues to be) widespread and easy to extract, as well as easy to work with, being both highly malleable and ductile as well as easy to smelt. Lead was mentioned in the Book of Exodus. Alchemists thought that lead was the oldest metal and associated it with the planet Saturn. Lead pipes that bear the insignia of Roman emperors are still in service. Lead's symbol Pb is an abbreviation of its Latin name plumbum.By the mid-1980s, a significant shift in lead end-use patterns had taken place. Much of this shift was a result of the U.S. lead consumers' compliance with environmental regulations that significantly reduced or eliminated the use of lead in nonbattery products, including gasoline, paints, solders, and water systems.
Extraction
Native lead does occur in nature, but it is rare. Currently lead is usually found in ore with zinc, silver and (most abundantly) copper, and is extracted together with these metals. The main lead mineral is galena (PbS), which contains 86.6% lead. Other common varieties are cerussite (PbCO3) and anglesite (PbSO4). But more than half of the lead used currently comes from recycling.In mining, the ore is extracted by drilling or blasting and then crushed and ground. The ore is then taken through a process developed in Australia in the 19th century at Broken Hill. A flotation process separates the lead and other minerals from the waste rock (tailings) to form a concentrate by passing the ore, water and certain chemicals through a series of tanks in which the slurry is constantly mixed. Air is blown through the tanks and lead sulphides attach to the bubbles and rise to form a foam which can be removed. The foam (which is around 50% lead) is dried and then sintered before being smelted to produce a 97% lead concentrate. The lead is then cooled in stages which causes the lighter impurites (dross) to rise to the surface where they can be removed. The molten lead bullion is then refined by additional smelting with air being passed over the lead to form a slag layer containing any remaining impurities and producing 99.9% pure lead.
Isotopes
Lead has four stable, naturally occurring isotopes: Pb-204 (1.4%), Pb-206 (24.1%), Pb-207 (22.1%) and Pb-208 (52.4%). Pb-206, Pb-207 and Pb-208 are all radiogenic, and are the end products of complex decay chains that begin at U-238, U-235 and Th-232 respectively. The corresponding half-lives of these decay schemes vary markedly: 4.47 × 109, 7.04 × 108 and 1.4 × 1010 years, respectively. Each is reported relative to 204Pb, the only non-radiogenic stable isotope. The ranges of isotopic ratios for most natural materials are 14.0-30.0 for Pb-206/Pb-204, 15.0-17.0 for Pb-207/Pb-204 and 35.0-50.0 for Pb-208/Pb-204, although numerous examples outside these ranges are reported in the literature.Precautions
Lead is a poisonous metal that can damage nervous connections (especially in young children) and cause blood and brain disorders. Long term exposure to lead or its salts (especially soluble salts or the strong oxidant PbO2) can cause nephropathy, and colic-like abdominal pains. Its historical use by the Roman Empire for water piping (and its salt, lead acetate, also known as sugar of lead, as a sweetener for wine) is considered by some to be the cause for the dementia that affected many of the emperors. The concern about lead's role in mental retardation in children has brought about widespread reduction in its use. Paint containing lead has been withdrawn from sale in industralised countries, though many older houses may still contain substantial lead in their old paint: it is generally recommended that old paint should not be stripped by sanding, as this generates inhalable dust. Lead salts used in pottery glazes have on occasion caused poisoning, when acid drinks, such as fruit juices, have leached lead ions out of the glaze. It has been suggested that what was known as "Devon colic" arose from the use of lead-lined presses to extract apple juice in the manufacture of cider. Lead is considered to have particularly nasty consequences for mothers in spe, i.e. girls and young women. For that reason many universities do not hand out lead in girls' analysises.The earliest pencils actually used lead, though pencil `leads' have been made for the last couple of centuries from graphite, a naturally occurring form (allotrope) of carbon.
Language Derivations
The Latin plumbum has given birth to a number of terms in the English language:The origin of the name of the fruit called a plum is not related.
- Plumbing, or system of piping, derives from the fact that pipes were once made of lead.
- Plumb bob or plummet, a small, pointed body of metal the weight of which is used to draw a string vertical under tension, refers to the fact that they were originally made from lead.
- Plumb wall is so-said because a plumb bob is used to find the vertical.
- Plumbing the depths derives from the use of the lead weight to draw the sounding line down to the bottom of the water body (or to the end of the line if the water's really deep!).
- Plumb crazy may derive from the fact that lead poisoning can cause insanity; or, according to the OED, from a U.S. sense of plum (derived from plumb) meaning 'completely'.
- Plumbism is the medical term for lead poisoning.
- Aplomb comes from the French à plomb, meaning plumb vertical, and therefore confident and cool.

In partner dancing, the two partners are labelled as the lead and the follow. Traditionally, a male partner leads and the female partner follows.A lead controls the way the dance will go. He decides which moves or figures will be danced, and how to move the follow. The follow does what the name implies, and follows the lead. For the lead and follow to interact with each other, a connection must be established. More advanced dancers will take many cues from each other, and communicating feedback to the lead which he incorporates into his own styling and leads.
Beginning leads try to control 99% of the dance. Advanced leads try to control 51% of the dance. The follow styles her own moves as she likes within the parameters communicated by the lead.
Sometimes the follow steals the lead and they reverse roles. Advanced swing dancers do this (to enhance their dance connection and?) to add a little fun into the dance.
The Lead has different steps to do than the follow. The Follow generally mirrors the Lead's footwork. If the lead begins on the left foot, the follow will begin on the right foot. In choreographed pieces, tandem charleston and other situations where the follow is in a tandem or shadow position, the lead and follow will use the same footwork.
In general, the lead starts by moving his feet, which moves his body, which moves his arms and the rest of him. In general, the follow starts by being pulled with her arm, which leads (pulls or pushes) her body, which directs her feet and the rest of her. Leads must initiate every move 1/2 count early for the energy and motion to ripple through and affect the follow.
One goal of partner dancing is to move in ways that one dancer alone cannot.

To Do
The partner that follows and the one that leads both have an inner drive to follow the soul of the dance and rhythm. A Salsa/Mambo dancer will always try to use the quick-quick-slow pattern. As dancing is derived from walking, the weight concentration is shifted from left to right and right to left on every beat. This leads to the need to move a foot. The leading partner decides where to move his foot and how the follow should move the foot. The leading partner has to comunicate the direction of the movement to the follow. As, traditionally, the right hand of the man is on the left shoulder of the woman, he can easily pull her body towards him (if the partner remains a body tensation), to comunicate a step forward (backward for the girl) the woman has to constantly put a little weight against the right hand of the man. When the man goes forward, and so does the hand on her shoulder, she is already going backwards before she notices the cue. The second important leading mechanism is the male left hand, which holds the female right hand. At no point it should neccessary for any partner to firmly grab the other's hand. It is sufficient to press the hand or even only finger tips slightly against each other, the following hand harmonically following the leading hand. The third important leading mechanism is the hip contact. Though not possible in traditional latin dances because of partner separation (like Rumba, Cha Cha, Tango Argentino, hip contact is a harmonic and sensual way of comunicating movement to the partner, used primarily in Standard or Ballroom Dances (English / slow Waltz, European Tango, Quick Step etc). Sometimes it is highly neccessary to get the figures done correctly and with more ease. In Caribbean dances the hip contact is more for the sensual touch, and quickly gets into the way of the more advanced figures.

(From Wikipedia, the free Encyclopedia)
In common usage, leadership generally refers to:
- the position or office of an authority figure, such as the President [1]
- a group of influential people, such as the union leadership [1]
- guidance or direction, as in the phrase "the leadership is not providing much leadership"
- capacity or ability to lead, as in the phrase "she exercised effective leadership."
Leadership as a position of authority
In On Heroes, Hero-Worship, and the Heroic in History, Thomas Carlyle demonstrated the concept of leadership as a position of authority when he said the following, in praising Oliver Cromwell's use of power to bring King Charles I to trial and eventual beheading "Let us remark, meanwhile, how indispensable everywhere a King is, in all movements of men. It is strikingly shown, in this very War, what becomes of men when they cannot find a Chief Man, and their enemies can." [1]
From this view, leadership emerges when an entity as "leader" manages to get deference from other entities who become "followers." And as the passage from Carlyle demonstrates, the process of getting deference is competitive in that the emerging "leader" draws "followers" from the factions of the prior "leaders."
In the Constitutional Convention of 1787, the American Founders rejected the idea of a monarch. But they still proposed leadership as a position of authority, with the authority split into three powers, the legislative, the executive, and the judiciary. That is, under the American theory, the authority of leadership derived from the power of the voters conveyed through the electoral college. And leadership as a position of authority could be shared among many people, including among the many legislators in the Senate and the House of Representatives. [1]
Determining what makes effective "leadership"
In comparing various leadership styles in many cultures, academic studies have examined the patterns in which leadership emerges and then fades, sometimes by natural succession according to established rules and sometimes by the imposition of brute force. Some scholars choose to judge the effectiveness of leadership by the size of the following that the "leader" can muster. By this standard, Hitler was an effective leader even if his promises were delusional and even if his troops forced the following. [1]
Other scholars maintain that an effective leader must unite followers to a shared vision that offers true value, integrity, and trust to transform and improve the organization and society. James MacGregor Burns calls this leadership that delivers true value, integrity, and trust transformational leadership that he distinguishes from mere transactional leadership that gets power by doing whatever will get more followers. [1] But the transformational quality of leadership is more difficult to quantify than would be a mere count of the followers that transactional leadership sets as a primary standard for effectiveness. That is, transformational leadership requires an evaluation of quality independent of the market demand that exhibits in the number of followers.
Leadership as a position of authority, comparison among the apes
Richard Wrangham and Dale Peterson, in Demonic Males: Apes and the Origins of Human Violence present the empirical evidence that only humans and chimpanzees, among all the animals living on earth, share a similar tendency for violence, territoriality, and competition for uniting behind the one chief male of the land. [1] And the chimpanzees are man's closest species relative; humans inherited 98% of their genes from the ancestors of the chimpanzees.
In comparison, the bonobos, the second closest species relative of man, do not unite behind the chief male of the land. The bonobos show deference to an alpha or top-ranking female that, with the support of her coalition of other females, is as strong as the strongest male in the land. That is, if leadership amounts to getting the greatest number of followers, then among the bonobos, a female almost always exerts the strongest and most effective leadership.
Some have argued that, since the bonobo pattern inverts the dominant pattern among chimpanzees and men with regard to whether a female can get more followers than a male, humans and chimpanzees both likely inherited gender bias against women from the ancestors of the chimpanzees; gender bias is a genetic condition of men. And the bias against women having leadership as a position of authority crosses all world cultures. As of 2002, Sweden has the highest percentage of women in the legislature at 43%. And the United States, Andorra, Israel, Sierra Leone, and Ireland are tied for 57th place with less than 15% of the legislature women. [1] Admittedly, those percentages are significantly higher than the occurrence of female chimpanzees becoming alpha of the community by getting the most followers, but the trends are similar in manifesting a general gender bias across cultures against females getting leadership as a position of authority over followers.
Do certain qualities a "leader" make?
Qualities sometimes associated with leadership may include talent, technical/specific skill, initiative, charismatic inspiration and service to a cause. The skills and practices of "leadership" may compare with management in the broadest sense of that word. In this connection one can view leadership as
- centralized or decentralized
- broad or focused
- decision-oriented or morale-centered
- intrinsic or derived from some authority.
Leadership Metaphors
- An effective leader resembles an orchestra conductor in some ways. She has to somehow get a group of potentially diverse and talented people -- many of whom have strong personalities -- to work together toward a common output. Will the conductor harness and blend all the gifts her players possess? Will the players be happy with the degree of creative expression they have? Will the audience be pleased by the sound they make? The conductor may have a determining influence on all of that.
Leadership by a group
In contrast to tolerating leadership as a position of authority, some highly successful organizations have adopted a pragmatic approach when they found that the role of boss costs too much in team performance. That is, in some situations, the maintenance of the boss is too expensive by either draining the resources of the group as a whole or impeding the creativity within the team, even unintentionally.
For example, the Orpheus orchestra which has performed for over thirty years without a conductor--that is, without a boss--for a team of over 25 members, has drawn discriminating audiences, and has produced over 60 recordings for Deutsche Grammophon in successful competition with the other world-class orchestras with the autocratic or charismatic conductors.

Rather than an autocratic or charismatic conductor deciding the overall conception of the work and then dictating how each individual is to perform the individual tasks, the Orpheus team generally selects a different "core group" for each piece of music; the core group as a team work out the details of the piece; the core group present their idea to the whole team; each member of the whole team then participates in refining the final conception, rehearsal, and product, including checking from various places in the auditorium how the sound is balanced and verifying the quality of the final recording--all without a boss.
At times the whole team may follow someone, but whom the team follows rotates from task to task among the members that the team finds capable. The Orpheus team even has developed seminars and training sessions for adapting the Orpheus Process to business. [1]
Other varieties of leadership
Accordingly, there are many uses for the word "leadership": it can mean a collective group of leaders or it can also mean the special if not mystical characteristics of those who lead (compare hero). Yet other usages have a leadership which does not lead, but to which one simply shows respect (compare the courtesy title reverend). Aside from the prestige-role sometimes granted to inspirational leaders, a more mundane meaning of the word "leadership" can mean "current front-runners": someone can take over the lead in a race, for example; or a corporation or a product can hold a position of market leadership.
In would-be controlling groups such as political parties, ruling elites, and other belief-based enterprises like religions or business, the idea of leadership can become a Holy Grail and people can come to expect transformational change stemming from the leader; such entities encourage their followers and believers to worship leadership, to respect it, and to strive to become proficient in it. Followers in such a situation may become uncritically obedient. Note the different connotations of a synonym of the word "leader" adopted from the German: Führer. Alternatives to the cult of leadership include co-operative ventures, collegiality, consensus, anarchism and democracy.
Aristocratic thinkers have postulated that leadership depends on one's blue blood or genes. Contrariwise, more democratically-inclined theorists have pointed to examples of meritocratic leaders, such as the Napoleonic marshals profiting from careers open to talent. In similar fashion, traditionalists recall the role of leadership of the Roman pater familias; against which feminist thinking posits emotionally attuned responsive and consensual empathetic guidance.
Many organizations aim to identify, foster and promote leadership potential or ability. See for example the Scouting movement.
For a more general take on leadership in politics, compare the concept of the statesman.
