Tyco International Ltd. Case Study: The Implications of Unethical Behavior

The following analysis of the Tyco International Ltd. (Tyco) case will discuss an historical summary of Tyco, including a backdrop on its former CEO, Dennis Kozlowski and Tyco’s culture at the time. The case will also define the role of ethical leadership’s contribution to the organizational success and the unethical and illegal conduct of Tyco’s leaders including the costs to its internal and external stakeholders, such as gross misappropriation of company funds on personal expenditures and duplicitous stock sales. Additionally, the case study will describe the importance of corporate social responsibility (CSR) to the organization, specifically, how Tyco failed to meet its CSR obligations. It also depicts the consequences to stakeholders with regard to cultural, environmental, and legal implications of CSR failures. Further, an examination is made of the outcome and punishment of events including the fairness of those punishments. Finally, the study will propose recommendations for ethical behavior with regard to corporate actions and organizational sustainability

Expectation adjustment in the housing market: insights from the Scottish auction system

This paper examines price expectation adjustment of house buyers and sellers to rapid changes in the housing market using data from Scotland where houses are sold through 'first-price sealed-bid' auctions. These auctions provide more information on market signals, incentives and the behaviour of market participants than private treaty sales. This paper therefore provides a theoretical framework for analysing revealed preference data generated from these auctions. We specifically focus on the analysis of the selling to asking price difference, the 'bid-premium'. The bid-premium is shown to be affected by expectations of future price movements, market duration and high bidding frequency. The bid-premium reflects consumers' expectations, adapting to market conditions more promptly than asking price setting behaviour and final sale prices. The volatile conditions of the recent housing market bubble are fully reflected in the bid-premium, whereas the asking and sale prices are much less prone to rapid movements

Exploring the role of multifunctional agriculture on the future of agriculture and rural development

The goal of this project was better understanding of the interplay between climate shifts and management practices as it affects soil organic matter (SOM) stocks in agricultural fields. Two advanced computer models were used to study this issue. [Keywords: WEPP, CENTURY, CARBON, EROSION

Testing the distinctiveness of prolonged grief disorder from posttraumatic stress disorder and depression in large bereaved community samples

Background: This study sought to test the distinctiveness of symptoms of prolonged grief disorder (PGD) from posttraumatic stress disorder (PTSD) and depression. Methods: Confirmatory factor analysis (CFA) and target exploratory factor analysis (EFA), were used to test the distinctiveness of PGD from PTSD and depression symptoms in a large sample of adults bereaved for at least six months (N = 1,917). Identified factors were explored in relation to demographic (i.e., age, gender) and loss-related (i.e., time since bereavement, nature of death, relationship to deceased, age of deceased, and frequency of contact with deceased) correlates. Results: The CFA model provided a good fit to the data, while the target EFA provided a slightly improved fit. All items loading strongly and significantly onto their respectively factors, and the IGQ items had few significant cross-factor loadings. All demographic and loss-related variables (except for death of a sibling and death from other causes) were associated with each of the factors, however, these associations were strongest for the PGD factor. Limitations: Participants were recruited using a non-probability sampling method and were from a relatively affluent Western nation. Conclusion: Findings from the current study demonstrate that PGD reflects an empirically distinguishable albeit related disorder to PTSD and depression in a sample of bereaved adults. The identification of correlates common to PGD, PTSD, and depression, as well as those unique to PGD, affords a comprehensive understanding of the risk factors associated with bereavement-related psychopathology.<br/

The International Grief Questionnaire (IGQ): A new measure of ICD-11 Prolonged Grief Disorder.

Prolonged grief disorder (PGD) is included in the 11th version of the International Statistical Classification of Diseases and Related Health Problems (ICD‐11). This study sought to test the validity and reliability of a new brief measure to screen for ICD‐11 PGD—the International Grief Questionnaire (IGQ). The psychometric properties of the IGQ were tested using data collected from two bereaved samples of adults from the United Kingdom (n = 1,012) and Ireland (n = 1,011). Confirmatory factor analysis demonstrated that a correlated two‐factor model best captured the latent dimensionality of the IGQ in both samples. Estimates of internal reliability were high, whereas the convergent and concurrent validity of the scale were supported through strong associations with external measures. Measurement invariance and differential item functioning testing showed no statistically significant difference in the latent structure of the IGQ nor the functioning of the IGQ items by age, sex, and nationality. For participants who were bereaved for more than 6 months, the rates of probable PGD derived from the IGQ were 10.9% and 15.3% for the Irish and U.K. samples, respectively. The IGQ is a brief, easy‐to‐use, self‐report screening measure that captures all diagnostic criteria of PGD set forth in the ICD‐11. Findings from this study provide initial support for the validity, measurement invariance, and reliability of the IGQ among two national samples

Decreased dopamine activity predicts relapse in methamphetamine abusers.

Studies in methamphetamine (METH) abusers showed that the decreases in brain dopamine (DA) function might recover with protracted detoxification. However, the extent to which striatal DA function in METH predicts recovery has not been evaluated. Here we assessed whether striatal DA activity in METH abusers is associated with clinical outcomes. Brain DA D2 receptor (D2R) availability was measured with positron emission tomography and [(11)C]raclopride in 16 METH abusers, both after placebo and after challenge with 60 mg oral methylphenidate (MPH) (to measure DA release) to assess whether it predicted clinical outcomes. For this purpose, METH abusers were tested within 6 months of last METH use and then followed up for 9 months of abstinence. In parallel, 15 healthy controls were tested. METH abusers had lower D2R availability in caudate than in controls. Both METH abusers and controls showed decreased striatal D2R availability after MPH and these decreases were smaller in METH than in controls in left putamen. The six METH abusers who relapsed during the follow-up period had lower D2R availability in dorsal striatum than in controls, and had no D2R changes after MPH challenge. The 10 METH abusers who completed detoxification did not differ from controls neither in striatal D2R availability nor in MPH-induced striatal DA changes. These results provide preliminary evidence that low striatal DA function in METH abusers is associated with a greater likelihood of relapse during treatment. Detection of the extent of DA dysfunction may be helpful in predicting therapeutic outcomes
