Chapter 5 the Court System, Chapter 6 Jails and Prisons, Chapter 7 Probation and Parole, and Chapter 8 the Juvenile Justices System. This being a hard choice to narrow these four topics down to one I have decided to discuss Chapter 6 Jails and Prisons. Jails and Prisons Jails and Prisons have no discrimination at all. You have all different kinds of people locked up behind bars different race, gender, beliefs, etc. They were first intended for incarceration of prisoners in Colonial America and the United States was local jails, which served primarily for detention prior to trial or execution rather than for punishment or rehabilitation of the criminal like now a days. After doing a little bit of research I believe the oldest penitentiary in the United States dates back to 1829, the Eastern State Penitentiary also known as ESP. Located in Fairmount, Philadelphia, Pennsylvania Eastern Sta te Penitentiary was opened on October 25, 1829 by John Haviland covering over 11 acres. During that time ESP held notorious criminals such as Willie Sutton and Al Capon. The building was the largest and most expensive public structure ever erected and became a model for more than 300 prisons worldwide (Rowan 2010).

Sociology and Social Science Canadian Recreational Users
Question: Discuss about theSociology and Social Sciencefor Canadian Recreational Users. Answer: Perspectives on Cannabis Legalization among Canadian Recreational Users In this assignment, the concept for the legalization of cannabis is taken into consideration. In the conventional period, people are against of consuming cannabis; however, in contemporary times, people in Canada strongly favored the legalization of cannabis use. Moreover, in this article, the perspective of only 41 adult Canadian users of cannabis is considered (Osborne et al., 2016). Among these adults, white-collar professionals and graduate students are also presents, who favor the consumption of the cannabis. It is also found from the case study, that when legislation bill for decriminalized of the cannabis consumption was proposed in Canada, the bill was not prorogued and ultimately the consumption of cannabis has become legalized. However, the decriminalized of the cannabis results in 52% rise in drug offences in which 12.2% of Canadians are of age 15 or older (Osborne et al., 2016). Thus, the bill was reformed and according to the Government framework for legalization and reg ulation of cannabis in Canada, they have set the legal age forpurchase at 18, others at 19 (Healthycanadians.gc.ca 2017). Another consequence that is highlighted in the given article is that whether the use of Cannabis will be increase after legalization. The Canadian Cannabis Coalition reforms the legislation for the use of cannabis for medical purposes and seed, grain and fiber production only (Osborne et al., 2016). Adults, who are from 21 to 61 years of age and are respondents for the research also portrays that the prohibition of cannabis is unjust and legalization of the consumption will help in reducing the unlawful drug trading that further results in less cost for criminal justice system. It also helps in reducing the stigma associated with cannabis use in the society. It is also found that maximum adults, who are a single middle-class community, prefer the legalization of cannabis consumption; however, middle aged people like mothers and legal secretary are against of the opposition to decriminalization and legalization strategies for cannabis. Moreover, from the undertaken research, it has be en found that 27 years old and other candidates also admits that the complete decriminalization should not be imposed and they should be allowed to grow and use the plants until a person gets affected by this activity (Osborne et al., 2016). In context with the age, professionals or educated people are aware of the consequences of the consequences of things like cannabis, drugs or alcohol. These educated people are also knowledgeable about the reason behind the governing legislation; however, people of same age but working in lower designations like construction site employees, retail and service industry people and white-collar clerical workers consider the present legislation to be restrictive (Osborne et al., 2016). The government of Canada also imposes pricing legislation on these product high prices on these products and extra tax payment. Most of the respondents of above 30 years of age, who use cannabis more than 10 years, are not affected by the imposture of the legislation and decriminalization as they believe a thing which is easy to grow by anyone can also be easily be consumed by anyone (Osborne et al., 2016). However, same aged people with family responsibilities consider the consequences of the harmful impa ct of consuming cannabis and thus have the control over their lifestyles.

Long Term Effects of Exercise on the Body free essay sample
Chronic responses are very specific to the type of training performed. â⬠¢ The frequency, duration and intensity of the training undertaken ââ¬â the greater these things, the more pronounced the adaptations â⬠¢ The individualââ¬â¢s capacities and hereditary factors (genetic make-up) Chronic Adaptations to Aerobic (endurance) Training: â⬠¢ Minimum period is 6 weeks â⬠¢ More evident over 12 weeks â⬠¢ Adaptations occur at both tissue and system levels. Cardiorespiratory Adaptations to Aerobic (endurance) Training Chronic cardio-respiratory adaptations are primarily designed for more efficient delivery of larger quantities of oxygen to working muscles. â⬠¢ They decrease cardiovascular disease (CVD)and other health-related illnesses. â⬠¢ Cardio-respiratory adaptations are best developed through continuous, fartlek and longer interval type training. Cardiovascular Adaptations: Cardiac hypertrophy (increased ventricular volume): â⬠¢ Enlargement of the heart muscle itself â⬠¢ Increase in size and volume of the ventricular chambers, particularly the left ventricle occurs. Significantly increases stroke volume Increased capillarisation of the heart muscle: â⬠¢ Increase in capillarisation of the heart muscle itself (Increase in capillary density and blood flow to the heart muscle) â⬠¢ Increased supply of blood and oxygen allows the heart to beat more strongly and efficiently during rest and exercise â⬠¢ Coronary protective benefit (therefore decreased risk of heart attack) Increased stroke volume of the heart: Heart ejects a greater volume of blood with each beat Stroke volume is greater at rest, during sub-max and max workloads for a trained athlete compared to an untrained person Eg. We will write a custom essay sample on Long Term Effects of Exercise on the Body or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Average stroke volume at rest: â⬠¢ Untrained male 70-80millilitres/beat, â⬠¢ Trained male endurance athlete 100millilitres/beat or more. During maximal exercise: â⬠¢ Untrained person ââ¬â 110 millilitres/beat â⬠¢ Trained person ââ¬â 130 millilitres/beat â⬠¢ Elite endurance athletes ââ¬â 190 millilitres/beat Trained and untrained females have lower stroke volumes than their male counterparts under all exercise conditions, mainly due to a smaller heart size Lower resting heart rate: The amount of oxygen required by an individual at rest does not alter as a result of their training status. At rest, it takes about 5 litres of blood per minute (cardiac output) to circulate around the body to supply the required amount of oxygen to the body cells Cardiac output (Q) is equal to stroke volume (SV) multiplied by heart rate (HR). Q = SV x HR However, if an individual has developed a greater stroke volume, the heart does not have to beat as frequently to supply the required blood flow Eg. Before training: Q = SV x HR 5L/min = 70 mL/beat x 71 beats/min After training: Q = SV x HR 5L/min = 100 mL/beat x 50 beats/min This is why resting heart rate is a useful indicator of aerobic fitness. Lower resting heart rate ââ¬â greater level of aerobic fitness â⬠¢ Elite ââ¬â 35bpm (marathon runners, triathletes, distance swimmers) â⬠¢ Average adult male ââ¬â 70bpm Lower heart rate during sub-maximal workloads: Mainly a result of increased stroke volume. The heart works more efficiently (More blood is pumped with each beat, and therefore the heart doesnââ¬â¢t have to work as hard to supply the required blood flow and oxygen supply) Slower increase in heart rate during exercise and a lower and faster attainment of steady state during exercise Improved heart-rate recovery rates: Heart rate of a trained athlete will return to pre-exercise levels (resting rate) in a much shorter time than that of an untrained individual. Increased cardiac output at maximum workloads: Cardiac output ââ¬â unchanged at rest and even during sub-maximal exercise regardless of training status. Does increase during maximal exercise. Maximal exercise ââ¬â may increase to values of: â⬠¢ 20-22 litres per minute for untrained male â⬠¢ 15-16 litres per minute for untrained females â⬠¢ 30 litres per minute or more ââ¬â highly trained athletes Lower blood pressure: May lower blood pressure, especially among people who suffer from hypertension (high blood pressure) Systolic and diastolic pressure levels may decrease during both rest and exercise Helps to reduce resistance to blood flow and reduces strain on the heart, thereby decreasing the risk of heart attack and other cardiovascular conditions Increased arterio-venous oxygen difference (a-VO2 diff): Trained individuals are able to absorb more oxygen from their bloodstream into their muscles during exercise performance compared to untrained subjects. This is due to: â⬠¢ Increased muscle myoglobin stores â⬠¢ Increased number and size of mitochondria within their muscles As a result of this, the concentration of oxygen within the venous blood is lower Subsequently the arterio-venous oxygen difference is increased during both sub-max and maximal exercise Therefore, and increased arterio-venous oxygen difference (a-VO2 diff) indicates a greater uptake of oxygen by the muscles with trained individuals Increased blood volume and haemoglobin levels: Total blood volume may rise by up to 25% (from 5. 25L to 6. 6L) for an average adult male with regular and sustained aerobic training. Red blood cells may increase in number and the haemoglobin content and oxygen-carrying capacity of the blood may also rise. Increased capillarisation of skeletal muscle: The average number of capillaries supplying each muscle fibres is: â⬠¢ 5. for trained athletes â⬠¢ 4. 4 for untrained athletes Changes to blood cholesterol, triglycerides, low- and high-density lipoprotein levels: Results may include a decrease in blood cholesterol levels, triglycerides and low-density lipoprotein (LDL). These substances are associated with the development of coronary heart disease. Aerobic training increases the ratio of high-density lipo-protein (HDL) to low-density lipoprotein. High-density lipoprotein is thought to provide a coronary protective effect, lessening the risk of developing coronary heart disease. Respiratory Adaptations Increased lung ventilation: More efficient and improved lung ventilation At rest and during sub-maximal exercise, ventilation may be reduced due to improved oxygen extraction However, during maximal workloads, ventilation is increased because of increased tidal volume (amount of air breathed in and out in one breath) and respiratory frequency (the number of breaths taken per minute). Pulmonary diffusion (the ability of the blood to extract oxygen from the alveoli) is also enhanced. Increased maximum oxygen uptake (VO2 max) Increase in the maximum oxygen uptake (VO2 max) during maximal exercise Improvement can be between 5ââ¬â30% following a regular and sustained training program This occurs because of adaptations such as: â⬠¢ Increased cardiac output â⬠¢ Increased red blood cell numbers â⬠¢ Increased a-VO2 difference â⬠¢ Increased muscle capillarisation â⬠¢ Greater oxygen extraction by the muscles Increased anaerobic or lactate threshold As a result of the adaptations that improve oxygen delivery and utilisation in the muscles, a higher lactate threshold (the point at which oxygen supply cannot keep up with oxygen demand) is developed. Advantage: The anaerobic glycolysis (lactic acid) system is not utilised as much until higher exercise intensities are reached. Consequently, lactic acid and hydrogen ion accumulation will be delayed until these higher work-load intensities are attained The athlete can ââ¬Å"work harder and for longer periodsâ⬠Muscle Tissue Adaptations to A erobic (Endurance) Training: Chronic aerobic training adaptations within muscular tissue are best produced through continuous training or high-repetition resistance training The following tissue-level changes can be observed within skeletal muscles following extensive endurance training: Increased oxygen utilisation: Aerobic training enhances the bodyââ¬â¢s ability to attract oxygen into the muscle cells and then utilise it to produce adenosine triphosphate (ATP) for muscle contraction This process occurs in the following ways: â⬠¢ Increased size and number of mitochondria ââ¬â Mitochondria are the site of ATP synthesis and where glycogen and triglyceride stores are oxidised (Greater oxidisation of fuels to produce ATP) â⬠¢ Increased myoglobin stores ââ¬â Myoglobin is the substance in the muscle cell that attracts oxygen from the bloodstream into the muscle. (Increase ability to extract oxygen) Increased muscular fuel stores: Increase in the muscular storage of glycogen, free fatty acids and triglycerides, along with the oxidative enzymes required to metabolise these fuel stores and produce ATP. Increased oxidation of glucose and fats: The muscular adaptations result in an increase in the capacity of muscle fibres to oxidate both glucose and fats The capacity of the aerobic system to metabolise these fuels is increased Increased oxidation of fats as a fuel source; due to: â⬠¢ Increased storage of triglycerides and free fatty acids â⬠¢ Increased levels of enzymes associated with fat metabolism Means that: At any given exercise intensity, a trained individual has to rely less on glycogen, thereby ââ¬Å"sparingâ⬠glycogen stores (Glycogen sparing) Therefore delaying the time to exhaustion due to glycogen depletion. Decreased utilisation of the anaerobic glycolysis (lactic acid) system: The enhanced capacity of the muscles to aerobically metabolise glucose and fats and other muscular level adaptations also means that there is less reliance upon the anaerobic glycolysis system to produce energy for ATP resynthesis until higher exercise intensities are reached. Allows athletes to work at higher intensities without exceeding lactate threshold. OR â⬠¢ Aerobic training results in an increase in the lactate threshold Eg. An athlete must run at a faster pace in order to accumulate the same amount of blood lactic acid as before training Muscle-fibre type adaptation: Some research has shown evidence that skeletal muscle switches fibre types from fast twitch to slow twitch as a result of endurance training. Skeletal muscle fibres are classified into three types: Type 1 ââ¬â Slow-twitch oxidative fibres: Contain large amounts of myoglobin, and large numbers of mitochondria and blood capillaries. â⬠¢ Red â⬠¢ Split ATP at a slow rate â⬠¢ Slow contraction velocity â⬠¢ Very resistant to fatigue â⬠¢ High capacity to generate ATP by oxidative metabolic processes. Type 2A ââ¬â Fast-twitch oxidative fibres: â⬠¢ Contain an extremely large amount of myoglobin, and huge numbers of mitochondria and blood capillaries. â⬠¢ Red â⬠¢ Very high capacity for generating ATP by oxidative metabolic processes â⬠¢ Split ATP at a very rapid rate â⬠¢ Fast contraction velocity â⬠¢ Resistant to fatigue Type 2B ââ¬â Fast-twitch glycolytic fibres: â⬠¢ Contain low myoglobin content, relatively few mitochondria and blood capillaries, and large amounts of glycogen â⬠¢ White â⬠¢ Geared to generate ATP by anaerobic metabolic processes â⬠¢ Fatigue easily â⬠¢ Split ATP at a fast rate â⬠¢ Fast contraction velocity Individual muscles are a mixture of the three types of muscle fibres, but their proportions vary depending on the action of the muscle and the genetic make-up of the individual Summary of muscle tissue adaptations to aerobic (endurance) training: Before Training |After Training | |Mitochondria (size and number) |Increased | |Glycogen Stores |Increased | |Myoglobin |Increased | |Triglyceride Stores |Increased | |Oxidation (both glucose and fats) |Increased |Anaerobic Glycolysis (lactic acid system) |Decreased | |Muscle Type Adaptation (number and type) |Increased | | | | | |Some conversion of: | | |Type 2B fibres to | | |Type 2A fibres | Chronic Adaptatio ns to Anaerobic Training Anaerobic training effects are best developed through sprint training, shorter and faster interval training, plyometric training, circuit training, and resistance (strength and power) training. The greatest adaptations occur at the muscle-tissue level. They include: Muscle hypertrophy: Significant enlargement of muscle fibres (mainly Type 2B fast-twitch fibres) resulting in muscular hypertrophy (an increase in the cross-sectional size of the muscle) and subsequently, greater strength
