TRICHOTILLOMANIA: EDUCATIONAL ISSUES

Twenty journal articles that examined the condition trichotillomania that are included in national journal databases created for educators were reviewed by a special education teacher. The articles were classified by publication type (e.g., empirical studies, descriptive articles, guides). Fourteen of the 20 articles were empirical studies. The studies were classified by research design (quantitative or mixed methods), the participants and data sources were identified, and the findings were summarized. The author analyzed the 20 articles utilizing a modified version of the Stevick-Collaizi-Keen method to develop themes that represent the essence of the literature. The four themes that emerged from the analysis include: (a) trichotillomania demographics; (b) social behaviors associated with trichotillomania; (c) trichotillomania and the school experience; and (d) trichotillomania treatments. The themes were connected to the role of the author as a special education teacher. Finally, the author reflected upon the changes the understanding illuminated by the analysis of the literature will have on his caree

Tightening Tensions: Fiscal Policy and Civil Unrest in Eleven South American Countries, 1937 - 1995

Efforts at fiscal consolidation are often limited because of concerns over potential social unrest. From German austerity measures during the 1930s to the violent demonstrations in Greece in 2010, hard times have tended to go hand in hand with antigovernment violence. In this paper, I assemble cross-country evidence from eleven South American countries for the period 1937 to 1995 about the extent to which societies become unstable after budget cuts. The results show a clear positive correlation between austerity and instability. I examine the extent to which this relationship simply captures the fact that fiscal retrenchment and economic slumps are correlated, and conclude that this is not what is driving the effect. Finally, I test for interactions with various economic and political variables. While autocracies and democracies show a broadly similar response to budget cuts, countries with a history of stable institutions are less likely to see unrest as a result of austerity measures.

Convertibility, currency controls and the cost of capital in Western Europe, 1950-1999

For most of the post-war period, Europe’s capital markets remained largely closed to international capital flows. This paper explores the costs of this policy. Using an event-study methodology, I examine the extent to which restrictions of current and capital account convertibility affected stock returns. The delayed introduction of full currency convertibility increased the cost of capital. Also, a string of measures designed to reduce capital mobility before the ultimate collapse of the Bretton Woods System had considerable negative effects. These findings offer an explanation for the mounting evidence suggesting that capital account liberalization facilitates growth.Cost of capital, liberalization, current account, capital account, convertibility

With a bang, not a whimper: Pricking Germany's "stock market bubble" in 1927 and the slide into depression

In May 1927, the German central bank intervened indirectly to reduce lending to equity investors. The crash that followed ended the only stock market boom during Germany’s relative stabilization 1924-28. This paper examines the factors that lead to the intervention as well as its consequences. We argue that genuine concern about the ‘exuberant’ level of the stock market, in addition to worries about an inflow of foreign funds, tipped the scales in favour of intervention. The evidence strongly suggests that the German central bank under Hjalmar Schacht was wrong to be concerned about stockprices-there was no bubble. Also, the Reichsbank was mistaken in its belief that a fall in the market would reduce the importance of short-term foreign borrowing, and help to ease conditions in the money market. The misguided intervention had important real effects. Investment suffered, helping to tip Germany into depression.Stock market, foreign lending, fixed exchange rates, asset prices, bubbles, Germany, monetary policy

Alteration of host cell ubiquitination by the intracellular bacterial pathogen Coxiella burnetii

The intracellular bacterial agent of Q fever, Coxiella burnetii, replicates within a phagolysosomelike parasitophorous vacuole (PV) in human macrophages and delivers effector proteins to the host cytosol via a Dot/Icm type IV secretion system (T4SS). The T4SS effectors are critical for PV formation and prevention of host cell death that allows sufficient time for bacterial replication. Recruitment of ubiquitin-related components to the C. burnetii PV is also predicted to be involved in PV formation and bacterial replication and is likely controlled by effector proteins. In this study, we assessed the role of the Dot/Icm T4SS in regulating ubiquitination by comparing subcellular localization of ubiquitinated proteins between cells infected with C. burnetii and a mutant that lacks a functional T4SS. Fluorescence microscopy showed ubiquitinated proteins surrounding wild-type C. burnetii PV but not phagosomes harboring T4SS-defective organisms. Immunoblot analysis showed altered ubiquitinated protein profiles throughout infection, suggesting C. burnetii impacts post-translational modification of host cell and/or bacterial proteins. Future studies will determine how T4SS-mediated recruitment of ubiquitinated proteins impacts C. burnetii-host cell interactions and eventual development of diseas

Serial defaults, serial profits: Returns to sovereign lending in Habsburg Spain, 1566-1600

Philip II of Spain accumulated debts equivalent to 60% of GDP. He also defaulted four times on his short-term loans, thus becoming the first serial defaulter in history. Contrary to a common view in the literature, we show that lending to the king was profitable even under worst-case scenario assumptions. Lenders maintained long-term relationships with the crown. Losses sustained during defaults were more than compensated by profits in normal times. Defaults were not catastrophic events. In effect, short-term lending acted as an insurance mechanism, allowing the king to reduce his payments in harsh times in exchange for paying a premium in tranquil periods. © 2010 Elsevier Inc.

Risk sharing with the monarch: Excusable defaults and contingent debt in the age of Philip II, 1556-1598

Contingent sovereign debt can create important welfare gains. Nonetheless, there is almost no issuance today. Using hand-collected archival data, we examine the first known case of large-scale use of state-contingent sovereign debt in history. Philip II of Spain entered into hundreds of contracts whose value and due date depended on verifiable, exogenous events such as the arrival of silver fleets. We show that this allowed for effective risk-sharing between the king and his bankers. The existence of statecontingent debt also sheds light on the nature of defaults – they were simply contingencies over which Crown and bankers had not contracted previously.sovereign debt, syndication, diversification, risk transfer, Spain
