...6 In my opinion Hope was not justified in deciding that the costs were for tooling modifications. There was not sufficient evidence to come to this conclusion, just some complicated explanations from USSC and inaccurate purchase orders and invoices. The evidence was not relevant to the audit objective. The specific products with modifications should have been traced back to their purchase orders. Instead the auditors just took the explanation of these orders from management. Finally the reliability of the evidence was not high, USSC had a lot to lose if it was concluded that they were indeed general production and the General Manger for Lacey had changed his position numerous times. The only reliable evidence was that of the independent law firm that concluded the purchase orders and invoices were not for tooling modifications. 5 The evidence that hope collected that supports USSC's claim that the charges in question were in fact for tooling modifications was the General Manager of Lacey Corporation (A division of Barden Corporation) goes back on his previous statement and confirms that the purchase orders and invoices were in fact for tooling modifications. USSC explained their position and said that they had instructed Lacey to make certain tooling changes that would result in improved efficiency in production of USSC products. When the audit team asked to take a tour of the Lacey plant to examine the actual production process the Lacey General Manger informed the audit...

...1. LE OFFERTE PUBBLICHE INIZIALI Con questo primo capitolo si vuole fornire una overview generale sulle offerte pubbliche inziali (in inglese Initial Public Offerings, ovvero IPOs). In particolare verranno presentati i contributi teorici della letteratura sul processo di quotazione e si andranno a definire quelle che sono le motivazioni, i ruoli e gli attori coinvolti in tale processo. Le IPO sono uno degli eventi di maggiore importanza e magnitudo nel ciclo di vita di una impresa, in quanto l’ammissione alla negoziazione dei titoli comporta una modifica alla struttura legale e di controllo dell’impresa. Il management infatti non deve rispondere solamente ad un gruppo concentrato di azionisti, bensì dovrà dare risposte ad un insieme insieme ben più disperso di investitori. Inoltre una IPO può impattare significativamente anche su quella che è la struttura finanziaria dell’impresa e pertanto sul valore d’impresa stesso. Esistono infatti diverse modalità con le quali si possono svolgere le offerte pubbliche iniziali. Una prima opzione è tramite le Offerte Pubbliche di Vendita (OPV). In questo caso gli azionisti già esistenti cedono sul mercato una frazione o la totalità del capitale da loro detenuto. Con questa modalità dunque gli azionisti dell’impresa raccolgono liquidità per se, ma non avviene una conseguente raccolta di capitale per l’impresa. Una seconda opzione è l’Offerta pubblica di sottoscrizione (OPS). Questa modalità consiste in un vero e proprio aumento di capitale...

...The Pendulum of PhD Student Role Identity David M. Penn Walden University April 12, 2015 The Pendulum of PhD Student Role Identity Bansel (2011) noted that as citizens traverse through life, each individual develops a framework of his or her own role identity and how the interpretation of identity interacts within the interpersonal, societal, and academic landscape (pp. 544). This development of role identity owes its genesis to the social-psychological disciplines as emergent and ephemeral rather than a static concept (p. 550). Jazvac-Martek (2009) asserted that the defining of academic identities is integral to the pursuit of all aspects of life but especially salient when focused on the PhD student, an area that lacks significant research and data (pp. 253-554). Barnacle and Mewburn (2010) contend that what the PhD track commitment requires, as a lifestyle, is an evolution in how we as students see ourselves and how we see our emerging roles in society (pp. 433-444). Jazvac-Martek (2009) compares the doctoral student’s journey is a transformative “rite-of-passage” for those who seek to embed academic inquiry into every aspect of his or her life and utilize the knowledge gleaned to further the common good of society as scholar-practitioners (pp. 253-262). According to Jazvac-Martek (2009), she reported that there needs to be perspicuous and prescribed support structures in doctoral education so that the doctoral students may come to understand his or her identity as...

...DISTRIBUTION OF LAPTOP BY SADIA ASLAM, Hard work has been considered a culmination of success .Lack of it, leads towards the edge of deterioration and darkness. Hard work is always ‘’key word’’ spoke by ancestors to make us aware its fruit. A student regardless of his/her affiliation to university or college always tries to gain prominent position in exams .None gratifies him either his post or employment but only the ‘’appreciation’’ joined by teachers, elders and dears. A chance also comes in our life to ‘’admiration’’ the form of laptop distributed by the government to polish the facilities of students and to include the spirit of progress. I really salute them, who have suggested to ‘bestow laptop to the proficient learns. Many of us consider that it is a kind to political propaganda but I myself ignores and rejects it, why a reasonable politic will spend his millions and billions in laptop’s division. This division is actually an undeniable blessing for those who have attained but what to speak of rest? It has been a fair distribution, Is there any right of private students who are still continuing their studies and are in constant struggle to quench the thirst of the knowledge. We are all Pakistani? Pakistan has been established in the name of ‘’equality’’ .Where is equality? I want...

...The various academic pressures inflicted upon students cause increased stress and anxiety which can impact mental health. Although everyone has experienced the pressures of stress and anxiety at least once in their lives, many do not understand the difference between them or that there is one at all. While stress is “a response to a threat in a situation”, anxiety is the body’s reaction to that stress (“Anxiety and Disorders at School” & “Stress”). There are many different types of anxiety. The most common anxiety disorders found in teenagers and young adults follow: Generalized Anxiety Disorder is classified by the “persistent, excessive and unrealistic worry about everyday things.” Meanwhile Panic Disorder is the spontaneous panic attacks...
