Jerusalem Crickets, Family Stenopelmatidae

Seeing a Jerusalem cricket for the first time can be an unsettling experience, even to those who arent prone to entomophobia. They look somewhat like giant, muscular ants with humanoid heads and dark, beady eyes. Although Jerusalem crickets (family Stenopelmatidae) are indeed quite large, theyre generally harmless. We know relatively little about their life history, and many species remain unnamed and undescribed. What Jerusalem Crickets Look Like Did you ever play the board game Cootie as a child? Imagine turning over a rock, and finding a Cootie come to life, staring up at you with a menacing expression! Thats how people often discover their first Jerusalem cricket, so its no surprise that these insects have earned many nicknames, none of them particularly endearing. In the 19th century, people used the expression Jerusalem! as an expletive, and thats believed to be the origin of the common name. People also believed (incorrectly) that these odd insects with human faces were highly venomous and potentially lethal, so they were given nicknames rife with superstition and fear: skull insects, bone neck beetles, old bald-headed man, face of a child, and child of the Earth (Nià ±o de la Tierra in Spanish-speaking cultures). In California, theyre most often called potato bugs, for their habit of nibbling on potato plants. In entomology circles, theyre also called sand crickets or stone crickets. Jerusalem crickets range in length from a respectable 2 cm to an impressive 7.5 cm (about 3 inches) and can weigh as much as 13 g. Most of these flightless crickets are brown or tan in color but have a striped abdomen with alternating bands of black and light brown. Theyre quite plump, with robust abdomens and large, round heads. Jerusalem crickets lack venom glands, but they do have powerful jaws and can inflict a painful bite if mishandled. Some species in Central America and Mexico can jump to flee from danger. When they reach sexual maturity (adulthood), males can be differentiated by females by the presence of a pair of black hooks at the tip of the abdomen, between the cerci. On an adult female, youll find the ovipositor, which is darker on the underside and located below the cerci. How Jerusalem Crickets Are Classified Kingdom – AnimaliaPhylum – ArthropodaClass – InsectaOrder – OrthopteraFamily - Stenopelmatidae What Jerusalem Crickets Eat Jerusalem crickets feed on organic matter in the soil, both living and dead. Some may scavenge, while others are thought to hunt other arthropods. Jerusalem crickets also practice cannibalism on occasion, particularly when confined together in captivity. Females will often eat their male partners after consummating the relationship (much like the sexual cannibalism of female praying mantids, which is better known). The Life Cycle of  Jerusalem Crickets   Like all of the Orthoptera, Jerusalem crickets undergo incomplete or simple metamorphosis. The mated female oviposits eggs a few inches deep in the soil. Young nymphs usually appear in the fall, less often in the spring. After molting, the nymph eats the cast skin to recycle its precious minerals. Jerusalem crickets require perhaps a dozen molts, and almost two full years to reach adulthood. In some species or climates, they may need up to three years to complete the life cycle. Special Behaviors of  Jerusalem Crickets   Jerusalem crickets will wave their spiny hind legs in the air to repel any perceived threats. Their concern is not without merit, because most predators cant resist such a fat, easy-to-catch insect. They are an important source of nutrition for bats, skunks, foxes, coyotes, and other animals. Should a predator manage to yank its leg loose, the Jerusalem cricket nymph can regenerate the missing limb over successive molts. During courtship, both male and female Jerusalem crickets drum their abdomens to call receptive mates. The sound travels through the soil and can be heard via special auditory organs on the crickets legs. Where Jerusalem Crickets  Live In the U.S., Jerusalem crickets inhabit western states, especially those along the Pacific Coast. Members of the family Stenopelmatidae are also well established in Mexico and Central America and are sometimes found as far north as British Columbia. They seem to prefer habitats with damp, sandy soils, but can be found from coastal dunes to cloud forests. Some species are restricted to such limited dune systems that they may warrant special protection, lest their habitat be adversely impacted by human activities.

Organizational Culture Is Within The Control Of Management

Introduction Interest in the area of corporate culture is said to have originated in the 1970s as a response to the success of Japanese management and the perceived failure of traditional organizational analysis (Hofstede, Neuijen, Ohayv Sanders, 1990; Ouchi, 1985; Martin Frost, 1999). Since then, research has flourished, with particular emphasis placed on the link between culture and corporate performance (Kilmann, Saxton Serpa, 1985). Observations of the most well-known, best run companies, like IBM and Google, seem to suggest that having a unique, cohesive culture can propel a company above the competition (Kilmann et al., 1985). Following from this, it makes sense that figuring out how to control culture to achieve competitive advantage has received a lot of attention from scholars and management alike (Anthony, 1994). In this essay, we will look to explore the extent to which organizational culture is within the control of management. To do this, we will begin by defining culture and shedding light on the debate that culture can be seen in one of two ways – as something that organizations have versus something organizations are (Nord, 1985; Schneider, Ehrhart, Macey, 2012). This contradiction defines the conversation on whether or not managers can control culture. On one hand, if culture is something an organization has, then we can think of it as a variable that one can control, at least to some extent (Meek, 1992; Baker, 1990). In contrast, those who argueShow MoreRelatedThe Role and Responsibility of Company Leadership in Shaping Organizational Culture1712 Words   |  7 PagesAccording to (Organic Workspaces, n. d) an organization’s culture refers to the observable, powerful forces in any organization, usually constituted by the employees’ shared values, beliefs, symbols , and behaviors.

Understanding Inclusive Learning free essay sample

Understanding Inclusive Learning and Teaching in Lifelong Learning Assessment Task 1 By Robert A J Gue Submission Date 3 May 2012 I have been asked by the Scout Association to give guidance on how to incorporate inclusive learning an teaching in to their training scheme to meet the needs of the leaders who come from diverse backgrounds. The Scout Association is part of a worldwide educational youth movement. The values, which underpin and inspire its work are embodied in the Scout Promise and Law and in the Purpose of the Association. Within this framework, the Association is committed to equality of opportunity for all members. To carry out its work the Association seeks to appoint effective and appropriate Leaders, and to involve other volunteers in supporting roles, all of whom are required to accept fully the responsibilities of their commitment. The Scout Association equal Opportunities Policy; equal opportunities for all; no person volunteering their services should receive less favourable treatment on the basis of, nor suffer disadvantage by reason of: †¢ age; †¢ class; †¢ ethnic origin, nationality (or statelessness) or race; †¢ gender; marital or sexual status; †¢ mental or physical ability; †¢ political or religious belief. We will write a custom essay sample on Understanding Inclusive Learning or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Source: Scout Association key policies. In todays society, we live in a multi cultural environment. This effects the local communities and this impacts on education and training. Organisations now have multi ethnic work forces, covering a wide range religious beliefs, nationalities and races. Cultures and attitudes have changed over the last 50 years and in todays society, you have mixed gender organisations , more openness sexual status changes in employment laws and disability laws which allows people with mental or physical abilities to work. The scout association is one of those organisations which has members from mixed religions, race, ethnic origins, mental and physical abilities. Therefore they have to adapt inclusive learning environment. Inclusive teaching means recognising, accommodating and meeting the learning needs of all your leaders under training. It means acknowledging that your leaders have a range of individual learning needs and are members of diverse communities: a leader with a disabling medical condition may also have English as an additional language and be a single parent. Inclusive teaching avoids pigeonholing leaders under training into specific groups with predictable and fixed approaches to learning.   The benefits of having inclusive teaching are; †¢ It takes a coherent approach which is proactive. †¢ Inclusive teaching has a strategy for delivering equal opportunities and diversity policies. †¢ Involves the whole organisation / movement. †¢ The training will match provisions to the student needs. †¢ It will incorporate regular reflection, review and refinement of strategies and methods that actively involve disabled leaders. Experience in scouting situations has demonstrated that adjustments made for disabled leaders/ scouts can often benefit all leaders and members from the scout sections. Inclusive teaching is good teaching. For example, when reviewing how to describe a diagram to a blind scout , it might become apparent that there is a better way to present the information for all scouts. In making your teaching inclusive you reassess the material you use in your teaching and the way in which it is delivered and assessed. The scout training programme should place leaders in the best possible learning environment, whatever those needs may be.

Spaces of his art are occupied B.) New tensions V. Constellations A.) Taboos B.) Death Working Thesis: The Catalan struggle and Spanish Civil War greatly influenced Joan Mir?'s art; Mir?'s techniques of forceful strokes with paint and ceramics enable Mir? to express his feelings and depict the Catalan people's struggle through art. Surrealism in the 1920s was defined as a fantastic arrangement of materials that influenced Mir?, due to the fact that he was one of the most original and sympathetic artists during the Surrealism periods. Mir? was born into the Catalan culture in April 20,1893 in Barcelona, Spain (Munro 288). Having to be born into the Catalan culture gave Mir? an opportunity to have an intense nationalist activity. In which much attention was paid not only to political expressions of the need for autonomy, but also to the re-Catalanizing of every day life (Higdon 1). ?It was necessary to fight so that Catalan, our language might be recognized as a cultural language? (?Mir). In 1910 Mir?'s parents bought a masia which is a sort of traditional farmstead of Catalonia, where the family has its roots on the paternal side. Mir? described the masia in his painting The Farm of 1921-1922 (Figure1). Clement Greenburg a close friend of Mir? who is also a critic, said that Mir?'s art is based on ideas ?of painting as an irrevocable two dimensional medium? (Munro 289). Greenburg also stated ?Mir? is known for his almost total lack of interest in political matters? (Munro 289). The only thing that really kept Mir? interested was his people and their culture. What really shot Mir? down was the Spanish Civil War, he stated that ?I am not in favor of separatism. I am in favor for Spanish unity, European unity, and World unity.? He believed that they should be able to celebrate their myths, and abide by their own laws (Higdon 1). Being Catalan was pretty hard on Mir? as well as his people and their culture. For one, the government tried to shut them out or at least make them in to a Spanish-speaking country. Yet the Catalans had to push on their struggle for freedom. Mir? used his paintings to show his urge for unity, and wanted his people to have the right to practice their customs (Munro 288). He was extremely devoted to his people and their aspirations. He wanted to bring out Catalan traditions as well as their language (Higdon 2). Mir? career in art was sort of brought on by destiny. In 1911 he enrolled at a design art school, taught by a man named Frances Gal?. Gal? was extremely strict and straightforward. His art was basically drawn in the form of a picture. Yet when he saw Mir?'s art he realized true potential and realized that Mir?'s use of paint strokes and use of two-dimensional shapes were unique. In 1914 Mir? painted a man wearing a Catalan ?liberty cap.? (Higdon2) After Mir? had completed small amount of his paintings they were brought to Barcelona for their safe keeping. Such as the Montroig, the Church and the Village (Figure 2), The Farm (Figure 1), Still Life with Old Shoe (Figure 3), and Women in the Night (Figure 4), When Mir? moved to Paris in the 1920s he experienced a wide variety of changes in one year, he had then moved from ?na?ve? of The Farm to the startlingly spare abstraction of the Hunter. After his experience with Paris, which only lasted for a couple of months, he went back to Barcelona until the beginning of the Spanish Civil War in 1932. Mir? began to show his anger in his art by drawing wild paintings. The spaces left between his artwork were occupied with monstrous figures, and

Search Warrants vs Arrest Warr essays

Search Warrants vs Arrest Warr essays How do we decide what is intrusion on an individuals life? Is it when physical or emotional harm is done to that person? But also what needs to be under consideration, is what limitations and what guidelines the official must be aware of when considering what actions to take upon that person. There are precedents and agreements that have been made before today, and these are what we must make the basis of our decision upon. The reality of the situation is that even though, the defendant has the rights to privacy and silence, the F.B.I. had not only probable cause that there were forged stamps and actual proof of the distribution of forged stamps, but also the ability to search for any object that could have caused a danger to the agents. We know the details about this particular case and we also know what the defendant feels was an intrusion upon his rights. For the record, the court feels it necessary to state the defendants rights, but also explain the process of searches and arrests. Protected by the constitution, each individual has the right to privacy, which is explained in the fourth amendment. This right is stated but not defined by a few solid principles, they follow; the individual has the right to be secure in their persons, houses, papers and effects. This allows for illegal or unreasonable searches, and excludes any evidence, which could incriminate that person; the second principle is a principle which clings to all rights guaranteed by the constitution and a rule of thumb that this court bases many of its judgments by, and it is the fact that one persons rights begin within oneself, but end at the beginning of the next persons nose. Since when the arrest was being made by the agents, they have the right over their own safety over the defendants right to defend himself physically, especially when the agents never inflicted any physical harm or never put the defendant into ph...
