Benefits of Nonverbal Communication Essay Example for Free

Benefits of Nonverbal Communication Essay Certain things are not conveyed by words or verbal means because individuals are not simply skilled to deliver or are not trained to explain in appropriate means or symbols. An officer can definitely learn from an understanding of nonverbal communication as he/she will be able to gain the nuances of an offender or parolee’s responses whether these are in consonance with the gaze in his eyes, the confidence of gait, or the studied looks that he may portray during the sessions that might transpire with the officer (Messina, Training in Nonverbal Communication). An officer who has spent a lengthy time studying people in this kind of profession, the difficulty usually lies in studying those who are mentally deranged, or the offenders who are so evil that they are capable to manipulate even the most intelligent officers, when possible. Their eyes convey differently where their talk or smiles carry them to a different level (Carrick, 2006). Art in any form conveys the reality that a human’s world is enriched by the kind of communication inherent in being human. Even one’s attire may speak a million things about the person or his intentions. People communicate both through verbal and nonverbal modes. Though we mistake verbal communication is clearer, yet often the reverse is truer (Messina, Training in Nonverbal Communication). People frequently understand our gestures more than our words. Hence, the adage â€Å"Actions speak louder than words. † Nonverbal communication is taught and performed frequently on an almost instinctive level. People get attention by using nonverbal signals and every so often the attention is usually due to an unpleasant manner by which these signals were conveyed. Most people who employ body language utilize such behavior to conceal the self for fear of rejection. The result would mean no real deep connections and deters other people to develop such deep and beneficial relationships. Many of those who realize their need try to unlearn years of covering up and attempt to make themselves known to avoid (Messina, Training in Nonverbal Communication). Every individual has inadequate stock of body language and utilizes the same manners to show specific emotionality. Body language and/or gestures, and a host of physical and psychological signals take place in clusters. This means that when a particular body language is used, it may not mean much as when it is used alongside many other forms of communication (Messina, Training in Nonverbal Communication). The officer then must continually make use of every opportunity as a learning experience as people are dynamic and continually changing. Reference: Carrick, Damien. 31 January 2006. The Law Report.

The Leaching Requirement During Irrigation Essay -- Soil Reclamation A

The Leaching Requirement During Irrigation The leaching of soluble salts from the plant rooting zone is a pivotal concern when irrigating cropland. Irrigation water is used to maintain crop productivity, so drought conditions need not occur to induce irrigation measures. Irrigation simply provides supplemental precipitation that may not be achieved through natural processes, i.e. rainfall. Basically, leaching is described as passing additional water through a medium to remove unwanted materials. This is usually achieved through two types of ponding. Additional water is pumped onto the soil surface and allowed to accumulate until surface ponding occurs. There are two mechanisms that perform this duty, continuous or intermittent ponding. Intermittent ponding, applying the excess water in intervals, is more favorable for milder climates where evaporation rates are low (NATO, 1994). Continuous ponding, applying all the water at once, may not be appropriate given geographical, climatic, or user-related constraints. Salts accumulate in the soil profile over time, therefore, leaching may serve as a form of soil â€Å"reclamation†. Normally, leaching curves are developed to determine the amount of water that may be actually required to reduce the initial soil salinity by a certain percentage (NATO, 1994). Although rainfall and the present soil already have saline concentrations, additional salts are added to the soil via irrigation water. Moisture is then extracted by the processes of evaporation and transpiration, and the salts begin to precipitate. Now, the salt balance of the soil profile changes: excessive salt concentrations are introduced without having adequate outlets. If located it the plant’s root zone, ... ...

Review Questions Chapter

Coral reefs are elaborate networks of crevices, ledges, and holes made up of calcium carbonate; coral polyps are tiny animals that build coral reefs by secreting a crust of limestone around their bodies that accumulate once multiple polyps die.Coral reefs help moderate atmospheric temperatures by removing CA from the atmosphere, act as natural barriers that help protect of the world's coastlines from erosion by battering waves and storms, provide habitats for a variety of marine organisms, produce about one-tenth of the global fish catch, one-fourth of the catch n developing countries, provide Jobs and building materials for some of the world's poorest countries, and support fishing and tourism Industries worth billions of dollars each year.Coral bleaching is when a coral becomes stressed and the algae on which it depends for food and color die out, leaving an underlying white or bleached skeleton of calcium carbonate; this occurs because of increased water temperatures and runoff of silt from the land. 2. The two major aquatic life zones are saltwater (marine) and freshwater life zones. 3. Phytoplankton (plank plankton) are multiple types of algae; Zooplankton (animal Lankan) are primary and secondary consumers which feed off phytoplankton (primary consumers) or other zooplankton (secondary consumers these range from protozoa to large invertebrates such as Jellyfish. Alternation are much smaller plankton that may be responsible for 70% of the primary productivity near the ocean surface. Nektons are strongly swimming consumers such as fish, turtles, and whales. Penthouses are bottom dwellers that attach themselves to one spot (e. G. Barnacles, oysters, worms, lobsters, crabs). Decomposer are organisms (mainly bacteria) which break down the organic compounds in the dead bodies and wastes of aquatic organisms into simple nutrient compounds for use by aquatic producers. 4. A major advantage of living In an aquatic life zone Is the fact that there Is high biodivers ity.A disadvantage Is that It Is constantly affected by human activities. 5. The four factors that determine the types and numbers of organisms found in these layers are temperature, access to sunlight for photosynthesis, dissolved 02 content, and availability of nutrients. 6. The marine systems provide climate moderation, carbon doodle absorption, nutrient cycling, waste treatment, reduced storm impact, habitats and nursery areas, emetic resources and biodiversity, scientific information, food, animal and pet feed, pharmaceuticals, harbors and transportation routes, recreation, employment, oil and natural gas, minerals, and building materials. . The coastal zone Is the warm, nutrient-rich, shallow water that extends from the Estuaries are regions where rivers meet the ocean. Coastal wetlands are land areas covered with water all or part of the year. Mangroves are the tropical counterparts of salt marshes. Temperature and salinity vary greatly in estuaries and coastal wetlands becau se seawater and freshwater mix, because tidal and river flows vary, and cause of land runoff.These have such a high NP because of high nutrient inputs from rivers and nearby land, rapid circulation of nutrients by tidal flows, presence of many producer plants, and ample sunlight penetrating the shallow waters. 8. The intertribal zone is the area between low and high tides. Rocky shores are beaches with a remarkable variety of species that occupy different niches in response to daily and seasonal changes in environmental conditions such as temperature, water flows, and salinity. Sandy shores are beaches with niches for different marine organisms. . Barrier islands are low, narrow, sandy islands that form offshore from a coastline. These are sought for human development because they are beautiful; however, these are at risk because the can be damaged or destroyed by flooding, severe beach erosion, or storms. The dunes should be protected because they serve as the first line of defense against the ravages of the sea. 10. Coral reefs are vulnerable to damage because they grow slowly, are disrupted easily, and only thrive in clear, warm, and fairly shallow water of constant high salinity.Humans impact coral reefs negatively by causing ocean warming, soil erosion, algae growth from fertilizer runoff, mangrove destruction, bleaching, rising sea levels, increased UP exposure, damage from anchors, and damage from fishing and diving. 11 . The open sea is the sharp increase in water depth at the edge of the continental shelf separated from the coastal zone. Its three main vertical zones are the epiphytic zone, the bathmat zone, and the abyssal zone. The NP per unit of area is so low because of its size. 2. Humans destroy coastal wetlands for agriculture and urban development, destroy mangroves for agriculture, development, and aquaculture, erode beaches because of coastal development and rising sea levels, degrade ocean bottom habitats by dredging and trawler fishing, an d damage coral reefs. 13. Freshwater life zones are the freshwater bodies of water. The two main types are standing (lentil) bodies of freshwater and flowing (lactic) bodies of freshwater. 14.Freshwater systems provide climate moderation, nutrient cycling, waste treatment, flood control, groundwater recharge, habitats for many species, genetic resources for biodiversity, scientific information, food, drinking water, irrigation water, hydroelectricity, transportation corridors, recreation, and employment. Unify, and groundwater seepage fills the depressions in the earth's surface. The literal zone is the zone near the shore which consists of the shallow sunlit waters to the depths at which rooted plants stop growing.The liniment zone is the open, sunlit water surface layer away from the shore that extends to the depth penetrated by the sunlight. The profoundly zone is the deep, open water where is too dark for photosynthesis. Then benthic zone is the lowest part of the lake where mos tly decomposer and detritus feeders are located. 16. The three types of lakes are the oligarchic (poorly nourished) lake, atrophic well nourished) lake, and the mesospheric (middle) lake. 17. Surface water is the water which doesn't seep into the ground or evaporate.Runoff is surface water once it flows into streams. A watershed is a land area that delivers runoff, sediment, and dissolved substances to a stream. The floodplain zone is generally populated by cold-water fish. The transition zone is inhabited by producers and cool- and warm-water fish species. The floodplain zone is populated by producers such as algae, contractible, and rooted aquatic plants along the shore. 18. Inland wetlands are lands covered with freshwater all or part of the time.Marshes, swamps, prairie potholes, floodplains, and arctic tundra in the summer are examples of inland wetlands. Seasonal inland wetlands are wetlands that are only covered by water during certain times of the year. 19. Dams, diversions, and canals fragment 40% of the world's 237 large rivers. Flood control methods built along rivers alter and destroy aquatic habitats. Cities and farmlands add pollutants and excess plant nutrients to nearby streams and rivers. Many inland wetlands have been drained or filled to grow crops or have been covered with concrete, asphalt, and buildings.

The Range of Statistical Data Sets

In statistics and mathematics, the range is the difference between the maximum and minimum values of a data set and serve as one of two important features of a data set. The formula for a range is the maximum value minus the minimum value in the dataset, which provides statisticians with a better understanding of how varied the data set is. Two important features of a data set include the center of the data and the spread of the data, and the center can be ​measured in a number of ways: the most popular of these are the mean, median, mode, and midrange, but in a similar fashion, there are different ways to calculate how spread out the data set is and the easiest and crudest measure of spread is called the range. The calculation of the range is very straightforward. All we need to do is find the difference between the largest data value in our set and the smallest data value. Stated succinctly we have the following formula: Range Maximum Value–Minimum Value. For example, the data set 4,6,10, 15, 18 has a maximum of 18, a minimum of 4 and a range of 18-4 14. Limitations of Range The range is a very crude measurement of the spread of data because it is extremely sensitive to outliers, and as a result, there are certain limitations to the utility of a true range of a data set to statisticians because a single data value can greatly affect the value of the range. For example, consider the set of data 1, 2, 3, 4, 6, 7, 7, 8. The maximum value is 8, the minimum is 1 and the range is 7. Then consider the same set of data, only with the value 100 included. The range now becomes 100-1 99 wherein the addition of a single extra data point greatly affected the value of the range. The standard deviation is another measure of spread that is less susceptible to outliers, but the drawback is that the calculation of the standard deviation is much more complicated. The range also tells us nothing about the internal features of our data set. For example, we consider the data set 1, 1, 2, 3, 4, 5, 5, 6, 7, 8, 8, 10 where the range for this data set is 10-1 9.  If we then compare this to the data set of 1, 1, 1, 2, 9, 9, 9, 10. Here the range is, yet again, nine, however, for this second set and unlike the first set, the data is clustered around the minimum and maximum. Other statistics, such as the first and third quartile, would need to be used to detect some of this internal structure. Applications of Range The range is a good way to get a very basic understanding of how spread out numbers in the data set really are because it is easy to calculate as it only requires a basic arithmetic operation, but there are also a few other applications of the range of a data set in statistics. The range can also be used to estimate another measure of spread, the standard deviation. Rather than go through a fairly complicated formula to find the standard deviation, we can instead use what is called the range rule. The range is fundamental in this calculation. The range also occurs in a boxplot, or box and whiskers plot. The maximum and minimum values are both graphed at the end of the whiskers of the graph and the total length of the whiskers and box is equal to the range.
