Solvability Factors - Essay Example Solvability factors, therefore, are the elements or situations that directly or indirectly affected the resolution of a crime which, as defined above, constitutes arresting and charging the offender or perpetrator. The following are solvability factors identified in the investigation of crimes such as homicide. The first group of factors involves those associated with the crime incident (Keppel & Weis, 1994). One factor is the commission of another crime. For homicide, these include robbery and breaking and entering which may aid in the investigation of the primary crime. Another factor is the time of the commission of the crime. Crimes that are perpetrated at broad daylight or at a time wherein many people are up and about will have a higher solvability due to the possibility of witnesses. Another factor under this category is the place of the crime. Crimes committed in residential areas are more likely to be solved than those committed in non-residential areas (Keppel & Weis, 1994). The second group of factors includes those associated with the vic... The third group of factors is the law enforcement organizational factors. Different strategies, regulations and other characteristics of crime detection agencies play an important role in the resolution of a crime. One factor is the amount of time that is devoted for a particular case. It is only logical that one investigator can handle a certain number of cases for a given period of time while it is quite understandable that an investigator can be more focused and be efficient when handling one case at a time (Wellford & Cronin, 1999). Another factor under this category is the number of agents or detectives for a particular division who can handle the same types of crime. When a certain investigator handling a case cannot, for any particular reason, pursue the investigation then assistance or replacement by another capable investigator is necessary (Muozos & Muller, 2001; Wellford & Cronin,1999). Another factor is the existence and efficiency of support staff that can increase the performance and rate of accomplishment of the details and processes undertaken by an investigator. Related to this is the separate function of data or evidence analysts that can help tackle the clues and questions posed by the data or evidences. Lastly, an important solvability factor related to law enforcement practice is teamwork inside the unit which roughly translates to good cooperation and communication frameworks among colleagues (Riedel & Rinehart, 1996). The fourth group of solvability factors falls under the crime scene factors. The foremost factor in this category includes the rapid or timely security of the crime scene and other places that may be

Use of Acupuncture for Treatment of Lateral Epicondylitis Essay Example for Free

Use of Acupuncture for Treatment of Lateral Epicondylitis Essay Lateral epiconylitis is a commonly encountered condition resulting from minor injury to the extensor muscles of the forearm, which originate from lateral epicondyle of humerus. This condition is characterized by pain and tenderness over the lateral epicondyle of humerus. Pain is typically present upon the resisted dorsiflexion of the wrist, middle finger or both (Buchbinder, Green Struijs, 2007). Lateral epiconylitis is known by many analogous terms like tennis elbow (TE), rowing elbow, tendonitis of the common extensor origin, peritendonitis of the elbow etc. In the United Kingdom, the incidence of tennis elbow in general practice has been estimated to be about four to seven per 1,000 persons a year (Buchbinder et al). Though TE is a self-resolving condition its symptoms can persist for as long as 18-24 months. Pain of tennis elbow can interfere with normal day to day functioning like carrying objects, lifting and gripping things etc. Though pain of TE can be initially cured with various conservative treatment modalities and rest, it can frequently recur after resumption of activity. Thus TE can cause significant amount of chronic pain and disability, which can lead to considerable morbidity and financial cost (Buchinder et al, 2007). Thus there is a need for an efficient treatment modality for TE. Till date, physicians and physiotherapists are uncertain about the exact etiology and best management option for patients with TE. There are several conventional therapies which are being used for treatment of TE. These therapies are believed to relieve pain, promote tissue healing and improve joint mechanics. These conventional therapies include anti-inflammatory medicines [NSAIDS (non-steroidal anti-inflammatory drugs) and corticosteroids], physiotherapy interventions (such as stretching and strengthening exercises), cast immobilization, ultrasound therapy, using ice packs, neural stretches, deep friction massages, surgery etc (Trinh, Philips, Ho Damsma, 2004). Various non conventional therapeutic modalities like acupuncture, pulsed electromagnetic field therapy, transcutaneous electric nerve stimulation etc have also been used for treatment of TE. In 1992, Labelle et al attempted to perform a quantitative meta-analysis in order to evaluate the therapeutic effectiveness of above mentioned treatment modalities (both conventional and non-conventional) for patients suffering from TE. They considered the results of 18 clinical trials conducted in the period from 1966 to 1990. From their analysis they concluded that the various randomized and controlled trials, which they had analyzed, were of poor quality and did not provide sufficient scientific evidence to support or oppose the therapeutic benefit of any of these conventional or non-conventional treatment modalities. Labelle et al (1992) did find some weak evidence supporting the beneficial effect of ultrasound therapy in comparison to that of placebo therapy in treatment of patients with TE. More recently, a systematic review of the literature, comprising of randomized controlled trials evaluating the effectiveness of various treatment options for TE was carried out by Assendelft, Green, Buchbinder, Struijs, Smidt, (2003). They have suggested significant beneficial effect of NSAIDS (both topical and oral) in comparison to placebo in the providing short term relief from pain in patients with TE. However they found little evidence regarding the beneficial effect of NSAIDS (both topical and oral) in providing long term pain relief. While the use of topical NSAIDS was not found to be associated with significant side effects, use of oral NSAIDS, typically aspirin was associated with significant side effects like gastro-intestinal bleeding etc. This review found limited evidence regarding the beneficial effects of steroid injections in comparison to placebo, local anaesthetic agents, elbow strapping or physiotherapy. Assendelft et al also found insufficient evidence to support long term or short term beneficial effect of treatment modalities like acupuncture, physiotherapy exercises, orthoses (elbow strapping), extra corporeal shock wave therapy and surgery. They have recommended long term use of oral and topical NSAIDS and physical therapies (elbow strapping, physiotherapy, etc and avoidance of provoking activities as the first line of treatment, especially in the early stages of the disease.   They have also suggested the use of corticosteroid injections as second line therapy for providing relief from pain. However the pain relief provided by corticosteroids is usually temporary in nature with the pain recurring again after a few months. Thus they have suggested that the patients receiving such therapy should be counselled about not subjecting the extensor muscles to increased activity during the pain-free period resulting from use of corticosteroid injections. On the other hand, Bisset, Paungmali, Vicenzino, Beller,   Herbert, (2005) from their systematic review of literature, comprising of studies evaluating   the effectiveness of   various physical interventions (non pharmaceutical or   non-surgical therapeutic modalities) for treatment of TE have shown short term benefit   with the use of physical interventions like ultrasound therapy, ionisation, and acupuncture. However no evidence of long term benefit due to these therapeutic modalities was observed in this review; benefit due to these interventions was usually seen to last between two to eight weeks. Bisset et al observed insufficient evidence regarding the beneficial effect of manual therapy (involving manipulation of elbow or cervical spine), use of elbow strapping and physiotherapy exercises in the management of TE. They also observed the presence of sufficient evidence that disapproved the beneficial effect of extracorporeal shockwave therapy and laser therapy in the treatment of TE (both in short term and long term). However they have indicated the requirement of larger studies in future in order to confirm this finding. Since no clinical study till date has been able to demonstrate definite clinical efficacy of any conventional therapeutic modality in treatment of TE, there has been increasing trend towards the use of non-pharmacological treatment modalities, especially acupuncture, since last two decades, for alleviation of chronic pain due to TE. One major advantage of using acupuncture for treating   pain of TE over the conventional anti-inflammatory drugs like NSAIDS (oral or topical), corticosteroids etc is that it is free from the numerous deleterious   side effects commonly associated with the use of these drugs. Also the evidence supporting the use of these conventional pharmacological interventions is no better than that supporting acupuncture [National Institute of Health (NIH), 1998]. Despite the growing popularity of acupuncture in treatment of pain related to lateral epicondylitis, presently, there is little evidence which confirms the efficacy of acupuncture in treatment of tennis elbow. The studies conducted until now have produced conflicting results. Bisset et al (2005), in their systematic review of literature considered four studies evaluating the therapeutic effect of acupuncture in treatment of TE. Three studies out of these four compared acupuncture with placebo whereas one study compared acupuncture with ultrasound. The overall evidence considered in this review supports short term beneficial therapeutic effect of acupuncture over placebo in patients with TE. Two studies, (Fink, Wolkenstein, Karst, Gehrke, 2002; Molsberger Hille, 1994) which compared acupuncture with placebo are described below in details. Fink et al (2002) conducted a study to evaluate the clinical efficacy of acupuncture in   treatment of TE. They also tried to compare the therapeutic effects produced by stimulating selected acupuncture points (as defined by traditional Chinese acupuncture) in contrast to those achieved through stimulation at non-specific points (these puncture points were at least 5 cm away from the traditional Chinese acupuncture points). The results of this study indicated that use of acupuncture with correct location and stimulation, in accordance to the recommendations of tradition Chinese acupuncture helped in significantly alleviating the pain, reducing disability of arms, shoulders and hands (measured through DASH questionnaire) and improving the strength of the extensor muscles in the patients suffering from TE. However these therapeutic effects (pain relief and muscle strength) of acupuncture were less evident in long term. In this study, at the time of follow-up after two months, though the overall functioning of the arm was observed to be better in the treatment group as compared to the control group, the differences in pain intensity and muscle strength were no longer found to be significant. The main aim of the study by Molsberger Hille (1994) was to find out whether acupuncture showed an intrinsic analgesic effect even after only one treatment session in comparison to that of placebo treatment for TE pain. In one single session of acupuncture treatment, patients in the treatment group were treated at a non-segmental distal point on the fibulo-tibial joint of the homolateral leg. The painful area of the elbow itself was not needled. The depth of insertion was 2 cm and during the procedure of needling, the patient was asked to move the painful arm. Patients were treated for a total of 5 min. Overall reduction in the pain score was 55.8% in the treatment group and 15% in the placebo group. After one treatment session, 79.2% (19 patients out of 24) patients in the treatment group reported pain relief of at least 50%, whereas in the placebo group only 25% patients (6 patients out of 24) reported pain relief. The average duration of analgesia after one treatment was 20.2 h in the treatment group whereas that after placebo was 1.4 h. All these results show that acupuncture has a statistically significant intrinsic analgesic effect in the clinical treatment of TE pain, which exceeds that of placebo treatment.   Since this study dealt with short term analgesic effects of acupuncture, further studies need to be carried out in future in order to evaluate the long-term therapeutic value of acupuncture for treatment chronic tennis elbow. Davidson et al (2001, cited in Bisset et al, 2005) conducted a study to compare the   therapeutic effect of acupuncture with that of ultrasound treatment in patients suffering from TE. Though significant improvement in two outcome measures i.e. pain reduction and disability prevention were observed in both the groups, no statistically significant differences in terms of these outcome measures were observed between the two groups. Thus this study indicates that there is no difference in therapeutic benefit between ultrasound and acupuncture in patients with TE. However it is difficult to reach to any definite conclusion from the results of a single study. More studies are required in future in order to arrive at a definite conclusion. In a publication by the NIH in 1998, it was determined that the results of various studies conducted till date has been promising enough to support the use of acupuncture as an adjunct treatment or an alternative to classical conventional therapeutic modalities for patients with TE. Trinh, et al (2004) conducted a systematic review of literature regarding use of acupuncture in treatment of TE, using the best evidence synthesis approach (BESA), which aimed at qualitative analysis of clinically homogeneous studies. The results of this review strongly suggested that acupuncture was an effective therapeutic modality for attaining short-term pain relief in patients with TE. Though there was a great deal of clinical heterogeneity between various studies considered in this review, five studies out of six studies considered in this review indicated that acupuncture treatment was more effective compared to placebo treatment. The studies conducted till date have failed to provide us with definite results. This can   be attributed to a variety of factors like: flaws in study design, heterogeneous treatment protocols, small sample size, inherent difficulty in the use of appropriate controls etc (NIH publication, 1998). Selection of method for performing the procedure in control group for these studies poses to be a difficult problem. Method of performing the   procedure in control group is important because the insertion of placebo needles itself results in inherent analgesic effect due to release of local ?-endorphins (opioid like substances), which can influence the outcome of the study too (NIH publication, 1998). Future research is recommended to resolve the issues discussed above. Thus there is a need for large scale, well-designed, multicentric, randomized control trials in future that will use standardized treatment protocol and appropriate methods for performing the procedure in controls. It is evident from the above discussion that various studies which aimed at assessing the   efficacy of acupuncture in treatment of TE had employed different processes for performing acupuncture, in terms of location of puncture points, depth of insertion of needles, the number of needles used, duration of treatment etc. In order to arrive at a definite conclusion regarding the efficacy of acupuncture in treatment of patients with TE and in order to maximize the chances for a successful treatment with acupuncture, there is a need for a uniform, accurate and complete description of the most effective method to be used for performing acupuncture in patients with TE. With this in mind, Webster-Harrison, White Rae (2002) conducted a study in order to develop a standardized treatment protocol for acupuncture therapy in patients with TE. They adopted a modified Delphi’s consensus technique to combine the opinions of fourteen British acupuncture experts into a standardized treatment protocol. This protocol contained eight items pertaining to the treatment of TE using acupuncture and has been described in table 1. The various items considered in this protocol were: selection of acupuncture points; length and diameter of needles used; depth of insertion; duration of treatment; interval between successive treatments; whether the needle should be stimulated or not; the type of response to be achieved upon stimulation and number of treatment cycles needed. Use of this protocol in randomized multicentric trials conducted in future is likely to give accurate results (Webster-Harrison et al). Conclusion From the discussion in this paper it becomes apparent that till date no study in published   literature has been able to demonstrate long term beneficial effects of any pharmacological, surgical or physical therapy in comparison to that of a placebo therapy for treatment of patients with TE. Among various non-pharmacological therapeutic options, acupuncture presents an effective and safe adjunct treatment or an alternative to classical conventional therapeutic modalities, especially in cases where these conventional therapeutic modalities had previously failed (NIH, 1998). Presently, the optimal treatment option for patients with tennis elbow in clinical care largely remains unclear. Acupuncture appears to be a lucrative treatment option for both clinicians and patients. However, the therapeutic benefits provided by use of acupuncture are not supported by sufficient evidence, at present. There is a need for well designed, high quality research studies, especially randomized control trials in future, in order to help in establishing the appropriate place for acupuncture in treatment of patients with TE in modern medical practice.

2D Colloidal Nanocrystal for Optoelectronic and Solar Cell

2D Colloidal Nanocrystal for Optoelectronic and Solar Cell Novel 2D colloidal nanocrystal for optoelectronic and solar cell applications Recently, 2D material has attracted tremendous attention due to their fascinating physicochemical properties. Particularly, the discovery of graphene, a single layer of carbon atoms arranged in a 2D honeycomb lattice has ignited the research on this class of 2D materials due to extraordinary mechanical, electric and optical properties not observed in their bulk counterparts. Considering graphene is a simple material composed of only carbon element, it cannot satisfy the increasing requirements of diverse applications due to limitations in the versatility and the tunability of composition, structure and functionality in addition to the paradox between the high-mobility Fermi−Dirac electronic structure and the need for a size-dependent band gap for traditional semiconductor devices. As a result, of paramount importance and interest is to search alternative 2D materials which possess much more flexibility and diversity of composition, structure, and functionality. Layered metal di chalcogenides such as WS2 and MoS2 have been extensively investigated. Like graphite, the atoms within the host layers form strong covalent bonding with relatively weaker interactions between layers such as van der Waals force. Consequently, micromechanical cleavage by Scotch-tape is the most straightforward method to obtain an individual layer while retaining their intrinsic host structure. Though it is crucial to evaluate their physical properties, this approach is time-consuming and the yield is also low. More recently, a direct liquid exfoliation where a suitable solvent is selected to stabilize cleaved crystallites was proposed to produce nanosheets. This process, comprised of ion-exchange, osmotic swelling, and exfoliation, is useful, but the concentration of unilamellar nanosheet in the solution is still very low with the yield no more than a few tens of percentage and the properties of the resulting nanosheets are dictated by their parent 3D materials, which loses the opport unities to design and control over chemical composition and structure. In order to meet the demand for fabrication of functional nanostructured electronic and optoelectronic devices, a facile process to produce large amount of 2D nanocrystal (NC) with possibility of tuning the properties is really imperative. Colloidal chemical synthetic route has been demonstrated highly attractive and powerful for their low-cost synthesis to obtain NCs from solution in excellent yield with a good uniformity in terms of chemical composition, surface properties, shape, and size. The complete control over size, shape and structure of the colloidal NCs via tuning reaction chemistry provides new pathways to design material where size or shape dependent properties can be exploited. In this project, the metal dichalcogenides such as MoS2 and WS2, typically with a trilayer structure of covalently interconnected layers of S, M, and S atoms, will be the main candidates. High performance solar cells built from them in 2D NC form is the final goal. As such, colloidal synthetic route will require balance of the reagent choice and reaction chemistry to accurately control the growth in the NC. All the advantages of 2D colloidal NCs will be exploited to fabricate solar cells in low cost while retaining efficiencies towards 10%. The objectives of this proposal are as follows: Develop colloidal synthetic routes for 2D colloidal NCs. Balance the reagent choice and ligand chemistry to achieve NC growth with controllable size, shape, and particularly thickness. Assemble 2D colloidal NCs to device scale area and perform correlative material studies with electronic properties (carrier lifetime, photoluminescence, carrier mobility). Fabricate all-inorganic NC solar cells and optimize in the device parameter space towards high power conversion efficiency. The project will be divided into three work packages (WPs) with a number of tasks in each WP structured to achieve the aims and objectives. Work Package 1 Controllable synthesis Task 1.1 Develop colloidal synthetic routes to 2D semiconductor NCs. Hot-injection method which involves the injection of a cold solution of precursor molecules into hot liquid will be employed due to the instantaneous formation of nuclei with slow growth of the existing nuclei but not to new nucleation for well controlled size and thickness. The product will be separated by centrifuging and washed up for characterization and analysis by XRD, electron diffraction and HRTEM for structure, and EDS and Raman for chemical composition. Task 1.2 Monitor and control the thickness, doping and their effect on the optical properties. Unlike 0D and 1D NC, in addition to control over composition and structure of 2D NCs, of particular interest is to rationally design and tune the thickness-dependent optical and electronic properties. For example, few-layer MoS2 has an indirect bandgap, but when it is thinned to single-layer, it becomes direct bandgap leading to enhanced photoluminesence. In this task we will monitor the effects of the thickness distribution particularly on absorption and photoluminescence (lifetime and QY). The latter will also be used as a metric to decide on the more promising routes for device fabrication, focusing on highly PL materials as the most promising candidates. In addition, substitutional or interstitial doping of metal sites within 2D NC may be employed to engineer optical characteristics. Work Package 2 Optoelectronic Properties of NC solids The presence of covalently bound ligands on the surface of colloidal NC provide a versatile synthetic handle for tailoring the structure, stability, and importantly electronic and optical properties. The deviation of composition and atom arrangement along the terminating edge and corner sites of 2D colloidal NCs also offers another way to tune their properties. One of the key determinant factors of the performance of solar cells is the carrier mobility. In this task we will investigate ligand exchange strategies using ligands that are shorter than 0.3 nm and contain functional head groups such as di-thiol groups and carboxyl-acid based groups. At the same time those functional groups should serve to passivate dangling bonds and therefore their electron-donating density will be chosen accordingly. We will monitor the effect of those ligands on carrier mobility by performing CELIV measurements in diode structures resembling an actual solar cell device architecture as well as using FET mobility measurements. In addition to high carrier mobilities NC solids for efficient solar cells call for long carrier lifetimes. Such long lifetimes can be achieved by suppressing trap states and recombination centers typically caused at grain boundaries and interfaces. The role of this task is to monitor the degree of passivation of the ligands utilized with Photoluminescence and PL-lifetime measurements. Work Package 3 Photovoltaic device fabrication, testing and optimizing Task 3.1 We will develop simple Schottky and bilayer heterostructures in which the sole photoactive layer is the 2D NC which can be achieved by using a transparent n-type high bandgap semiconductor to form a junction. We will then perform carrier lifetime and recombination-rate characterization employing transient photovoltage and photocurrent measurements. Task 3.2 Optimization of heterojunctions based on 2D NCs. We will perform a device optimization study in which we will study the effect of layer thickness and contact selection to maximize efficiency. The optimized thickness will be sought as a combination of the expected carrier diffusion length and achievable depletion widths based on the mobility, lifetime and carrier density of the semiconductor. Appropriate contacts will be investigated based either on inorganic (MoOx) or organic hole transport layers (electron blocking layers).

An Analysis of The Building Essay -- The Building

An Analysis of The Building Larkin put "The Building" in the middle of his collection for a reason, it is a pillar that supports the rest of the collection with its long lines and many verses, and because of this, is maybe a bit more clearer than some of his other poems in the ideas and views that are expressed through it. Of course, being a Larkin a poem, there is the obligatory underlayer which so many people miss, but in "The Building" it is easier to discern and comprehend. The title of the poem, "The Building" already hints at the main theme of the poem. The word "building" is a very vague term and in it's vagueness one can make out the fright of the author for this building, he cannot specify that it is a hospital as if not saying the word will make it go away. At the same time in this poem, Larkin makes out the hospital as the real world, everything around it is fake so that the word "building" is put in contrast to his view of what it really is. The poem starts in this indistinct manner and moves onto a much more definite reality: death. The first thing we discover about the building is the way it dominates the author's view, of all buildings he can see it is the tallest, it "shows up for miles". Although he doesn't want to know what it is, it dominates his view and his destiny - all men and women end up in the hospital before they die, and there is that sense again, of Larkin's fear of death. He sees that the hospital is the real life, all else is false, you delude yourself all your life about death, pretending that it doesn't exist yet when you get in the hospital you finally have to face the truth. He names the places he would like it to be: a hotel, an airport lounge, a bus, but he can no longer d... ... to die. Not yet, perhaps not here, but in the end, And somewhere like this." As in most of his poems, he starts with a fear of something, in this case death but comes to realise later on that in fact it is only an inevitable part of life. And he also comes to understand that if people weren't so scared of death than life would be less valued as he hints to in the last part of the poem: "...a struggle to transcend The thought of dying, for unless its powers Outbuild cathedrals nothing contravenes..." The poem ends disturbingly with "With wasteful, weak, propitiatory flowers". The structure of the poem with nine verses of six lines adds up to 63, but that last odd line makes it more regular, it makes 64 which suggests 8x8, so that the last line might seem a bit irregular and odd but it also completes the poem (and also the rhyme scheme).

Critical Criminology

CHAPTER 1 CRIME THEORY: CRITICAL CRIMINOLOGY There could be different reasons of increasing crimes. One of the obvious reasons is poverty and social injustice. Most of the people engaged in crime either don’t have proper source of income or they are socially discriminated. So the main reason of crime is poverty and social injustice. Most of the places with high poverty and social injustice have high crime rate (Jerry, 1995). The most important policy implications that would be most successful in reducing crime and/or rehabilitating convicted offenders in long term are critical criminology theories. In critical criminology crimes are defined in terms of domination. That is if some class or group is dominant than they can make social concept lawful and unlawful. Lower class, single parent women, poor people and minorities mainly suffer due to domination factor by others (Hopkin, 2001). 1. 1 Broad Problem Area: â€Å"Importance of Critical Criminology in Reducing Crimes† Justice system around the world is not strong enough to reduce crimes. So we need alternative approach through which criminals can become useful and productive member of the society. It’s not easy to completely change justice system but it’s not difficult to make criminals better citizens as well. Critical criminology is an effective way to reduce social injustice and crimes. Concept of critical criminology came in late sixties and early seventies. It mainly deals with the dominative and differential relation between different groups on the basis of demographic factors such as age, gender, ethnicity, minorities, cultures, values and social groups. This culture and social diversity was created due to migrations and human nature. Social indifferences are another form of injustice. It’s important to support these peoples who are being discriminated (Bauman and Tester, 2001). According to Wikipedia Encyclopedia, in critical criminology the scope of crimes is defined differently on the basis of social circumstances and time period of their occurrence. Critical criminology is somewhat different from basic study of criminology that deals with criminals and their behaviors. The basic idea of critical criminology is that the social and past trends would define whether some thing is unlawful or not at given time. There could be different things that are considered to be unlawful in past but now they are lawful and same goes with those things which are lawful in past but now they are unlawful. Such as marriage of homosexuals was considered to be unlawful in past but now with the passage of time societies are accepting this and making laws to protect marriages of homosexuals. This is not possible that all the studies on crimes are dealing with modern social life but they are some way connected to the present (Garland, 1999). There could be different theories that could emerges from critical criminology such as conflict theories, feminist theories, & postmodern and peacemaking theories. A conflict theory of criminology is not accepted largely by criminologist because they think conflict theories don’t address the criminal activities in socialist and capitalist societies. Feminist theories define that crime done by males and crimes done by females should be viewed differently. They give new aspect to criminology on the basis of gender. Critical criminologists have different views and way of resolving crimes. These two theories are mainly recognized around the world. Main emphasis is given to relation between criminals and societies. Even feminist criminologists don’t properly represent gender prospective and take back their views after failure of other criminologists (Van, 1997). There is a difference between critical criminology and conventional criminology. Conventional criminology is not dealing with activities which are affecting life of thousands of people such as politicians’ decisions that could affect millions of people, corporate scandals that affected thousands of workers, stock market manipulations that affected thousand of investors and also discriminations of minorities that have no end. Conventional laws do not answer these structural disparities that helps dominate group to take advantage of it. Conventional criminology is dealing with state defined crimes but not the crimes that are harming society ocially (Stephen, 1983). Criminologists working to find ways to resolve or to reduce crimes are not able to identify or not able to provide any authentic procedures to resolve crimes (Braithwaite, 1998). And also they didn’t even give importance to issues or difference created due to power and state (Cunneen and White 1996). This is still a claim that critical craniologist are more inclined towards gaining some pos ition and recognition rather than actually doing some thing for society to protect human rights and to promote justice in society. Since 1960, activists in human rights and social justice are molding progress in critical criminology theory. There is a relation between criminologists and social & human right moments (Braithwaite, 1989). Critical criminologist overstates the crime problem in society. Instead of removing the mystery that crimes are not their and its media created etc. they should accept crimes as a dilemma of powerless. They must not criticize criminal system by keeping this fact in mind that it is created by undue protection given to the privileged class. There is a cause effect relationship between crimes and poverty, racism, discrimination, social injustice, racisms etc. Critical criminoloiges must keep this in mind while evaluating crimes. However, critical criminology and traditional criminology should not work in different ways rather they should work together in the same way. (Cohen, 1998). 1. 2 Problem Statement: â€Å"Is Critical thinking is helpful to reduce crimes and able to reduce social injustice from society†. 1. 3 Purpose & Significance of Study The main purpose of this study is to identify the importance of critical criminology in order to reduce crimes. This study will also identify other ways to reduce crimes and their effectiveness. And it will also explain what factors are responsible for crimes. This study will help policy makers and law enforcing agencies to avoid crimes by using proper critical criminology theories. 1. 4 Research Questions The aim of this research is to study, 1) How do people perceive that critical criminology can reduce crimes? 2) How do people perceive the role of critical criminology in order to reduce injustice from society? ) How do people perceive that critical criminology approach is better way to reduce crime rather than conventional criminology approach? 1. 5 Theoretical Diagram In this diagram crimes reduction is dependent variable which depend on critical criminology that is independent variable. Critical Criminology method that properly identify social injustices that could change offend er future behavior towards crime and society support to accept these people as a useful member of society are intervening variable. These variables can assure the effectiveness of counseling treatment to reduce crimes. Independent Variable Dependent Variable Intervening Variable CHAPTER 2 RESEARCH DESIGN AND METHODOLOGY This chapter presents the basic methodology and requirement in research. It includes the methods of research, the respondents and their description, sources of data, the sets of research instruments that were used, the treatment of data, and the statistical tools, which were used in this study. 2. 1 Method of the Study: The research utilized the descriptive method in acquiring information for evaluation and analysis. The descriptive survey was the general rocedure employed in a study that has for its chief purposes the description of the phenomena that is importance of critical criminology theory in reducing crimes from society by providing social injustice. 2. 2 Sample, Type of Questionnaire, & Treatment of Data: The population for this research study was the general public. A random sample of 50 was taken from different places and different groups such as law enforcing agencies, c ommunity, criminologist etc. Researcher selected probability sampling, because every person had an equal chance of being selected.

The formula is; % = F/N ? 100 % = percentage F = frequency N = number of respondent CHAPTER 3 QUESTIONNAIRE ANALYSIS, FINDINGS & CONCLUSION 3. 1 Questionnaire Analysis: Respondent responded in the following way: Topic Based on Questionnaire |Highly Disagree | Disagree | Moderately | |Highly Agree | | | | | |Agree | | |Critical criminology is providing support to poor, minority |11% |18% |25% |42% |4% | |and low social class group | | | | | | |Critical criminology theory is important to reduce social |0% |0% |14% |57% |29% | |differences | | | | | | |Main reason of increasing crime rate is soci al injustice |3% |10% |21% |40% |26% | |Critical criminology is playing important role in order to |11% |28% |31% |26% |4% | |highlight social injustices | | | | | | |Critical criminology is different from conventional |29% |36% |19% |10% |6% | |criminology | | | | | | |There is a difference of opinion among critical criminologist |18% |24% |21% |30% |7% | |Critical criminologists are criticizing conventional justice |17% |19% |23% |35% |6% | |system that it supports to powerful class | | | | | | Social movement regarding human rights and social justice is |0% |0% |9% |55% |36% | |supporting critical criminologist | | | | | | |Critical criminologists are working for their recognition |26% |37% |21% |10% |6% | |rather than to support social injustice | | | | | | 3. 2 Findings & Conclusion: On the basis of the questionnaire, most of the respondent responded that critical criminology is providing support to poor, minority and low social class group and critical criminology theory is i mportant to reduce social differences †¢ On the basis of the questionnaire, most of the respondent agreed on a statement that main reason of increasing crime rate is social injustice and critical criminology is playing important role in order to highlight social injustices †¢ On the basis of the questionnaire, most of the respondent responded moderately agreed on a statement that critical criminology is different from conventional criminology and there is a difference of opinion among critical criminologist †¢ On the basis of the questionnaire, most of the respondent responded that critical criminologists are criticizing conventional justice system that it supports to powerful class and social movement regarding human rights and social justice is supporting critical criminologist. In these days societies are giving more focus to crime, victimization, regulation, punishment, with respect to human rights, equity, social justice, well being of the community, and globaliz ation. More activists are taking interest in decreasing discrimination and imbalances in societies. They are trying to gather more people to take action for the betterment of society and this will affect both antiestablishment and establishment criminologies. If model of Mutualism develops with the same pace than critical criminologists have to revise their studies and ways to resolve crimes. They have to establish the relation between antiestablishment and establishment criminologies not for individual but for the society. Now societies are moving from equal rights and equal justice to human rights and social justice due to social movement to protect rights. References: Bauman, Z. , & Tester, K. (2001).

Founding Brothers Essay

The novel, Founding Brothers, written by Joseph Ellis is a thought provoking novel on the intertwined lives of George Washington, Thomas Jefferson, James Madison, John Adams, Alexander Hamilton, Aaron Burr and Ben Franklin. Ellis calls the 1790’s the most decisive decade in our country. The author exemplifies three major points in our nation’s history: George Washington and his prominent legacy; the collaborative yet antagonistic relationship between Thomas Jefferson and John Adams; and the many problems of the young union during its revolutionary era. George Washington was a monumental character and played a vital role in the molding of our country. Although, his reputation was nearly impeccable, he was great in stature, standing at six foot four. The farewell address was a key element to Washington’s legacy. In this he displayed how grateful he was to have such a remarkable opportunity to serve his country, although this only was the beginning part of his speech. Secondly he decided to stress the importance of the union. But it started in 1776 when Washington was being described as â€Å"Father of our Country† prematurely. Even Ben Franklin acknowledged Washington’s supremacy. In the 1790’s Washington was well known, he was the presiding officer at the Constitutional Convention and the chief executive of the federal government. â€Å"Washington was the core of gravity that prevented the American Revolution from flying off into random orbits, the stable center around which the revolutionary energies formed† (Ellis 121). He impacted the government tremendously with his way of thinking and his attitude toward the need for national unity. He talked about independence from foreign nations; he devoted several paragraphs to this in his in his address. Washington always made the well- being of the country first. For example, when Continental Congress wanted help the French with an invasion of Canada, Washington opposed. He feared that that putting the France in possession of that capital that they would become greedy, and doubted that they would withdraw once they were ensconced in Canada. I think that he may have felt that also, America was young and still growing as a country. He was criticized for this decision. In closing on Washington’s legacy, I feel that there were many reasons why he retired. In short, he was just getting old and probably couldn’t take the political pressure. He was also going through a physical decline. Washington intended for his farewell address to be advice to his countrymen. He wanted them to sustain without, and without a king. Adams and Jefferson were indeed friends but had different agendas on how the country should be run. Their relationship was unique; they were great friends but even better competitors. The presidency drove them apart. Adams was a federalist, and Jefferson was a democratic republican so to speak. Through the Continental congress and diplomatic missions they became close friends. As they worked more together Adams developed more respect Jefferson, although he was less effusive. The low point of their relationship was definitely after the election in 1800. After this their relationship became more antagonistic. As politicians and colleagues they went through many phases. After the election they did not speak for a long 12 years. Adams felt that Jefferson had betrayed their friendship. After the death of Jefferson daughter, Abigail Adams began to exchange letters of condolences. Jefferson confused it as an invitation to reconcile with Adams family. The two disputed briefly, John didn’t find out until several months later. Finally in January of 1812, Adams sent a letter from Quincy to Monticello. â€Å"Why then, did Adams take the fateful step, which led to a fourteen year exchange of 158 letters, a correspondence that is generally regarded as the intellectual capstone to the revolutionary generation and the most impressive correspondence between prominent states in all of American history† (Ellis 223)? For the last 15 years of their lives they contacted each other through letters and rebuilt their friendship. On the 50th Anniversary of the signing of the Declaration of the Independence, both Thomas Jefferson and John Adams died within hours of each other. They will never be forgotten for the inevitable and timely contributions to our young country. In the introduction Ellis describes the American Revolution perfectly with the statement â€Å"No event in American history which was so improbable at the time has seemed as inevitable in retrospect as the American Revolution†. America’s victory seemed beyond improbable seeing as how England had the greatest army of the Revolutionary era. The young colonists chose to seek out alliances with the French, Dutch, and Spanish due to their lack of monetary resources, experience or even the pure man power. British beforehand, even tried attacking the colonists politically which had their in leading to an inevitable rebellion. They initiated taxes, and other events such as the Boston Massacre took place that ignited the young colonists to take stand against Great Britain. Though faith, inspiration and prosperity the Americans shocked the world, defeated the odds and took the victory in 1783, securing their new independent world. This victory inspired countries worldwide to rebel against the tyrannical empires that were controlling them. This victory is evident in today’s society as America thrives as country that influences others and still is, independent. Founding Brothers truly exposes a much more personal point of view of our founding fathers and their irrefutable destiny. Joseph Ellis targets critical elements of their and what they thought was best for the young country of America. They molded something bigger than themselves during this revolutionary era. The author really brings to life the intricate detail of Washington’s legacy and the partnership between two great leaders Thomas Jefferson and John Adams. Joseph Ellis’ statement was more than valid; it justifies American in a few short words.
