Unless we challenge long-held assumptions about how business leaders are supposed to act and where they're supposed to come from, many people who could become effective global leaders will remain invisible, warns Harvard Business School professor Hill. Instead of assuming that leaders must exhibit take-charge behavior, broaden the definition of leadership to include creating a context in which ...

Background Often a patient with prolonged fever requires a complex medical approach involving several medical specialties and extensive laboratory investigations. Case report We report the case of a 32 year male who presented for prolonged febrile syndrome about 2 months, chills and discreet urinary symptoms, initially interpreted to be a chronic prostatitis and treated for about 40 days with f...

Three dimensional (3D) modeling has been an important process in documenting archeological sites. Unlike conventional 2D drawings, 3D models provide both archeologists and future reconstruction workers with accurate geometrical data of the object in digital form, thus enabling various experiments and research. For this cause, archeological institutions usually employ either the terrestrial lase...

Folder navigation is the main way that computer users retrieve their personal files. However we know surprisingly little about navigation, particularly about how it is affected by the operating system used, the interface presentation and the folder structure. To investigate this, we asked 289 participants to retrieve 1,109 of their own active files. We analyzed the 4,948 resulting retrieval ste...

As the schizophrenia and psychosis recovery research continues to accumulate, we find the first stirrings of a profound shift in our understanding of these confusing disorders. On one hand, we find increasing evidence that schizophrenia (and other closely related psychotic disorders) may not be the manifestation of a diseased brain after all; on the other hand, we find evidence that, in spite o...

We report a case of multinodular thyroid goiter in an 80-year-old man who successfully underwent tracheal stent placement for respiratory distress caused by the thyroid goiter and following two radiofrequency (RF) ablation sessions performed for thyroid volume reduction. This sequential treatment allowed elective stent removals four weeks after the second RF ablation session because the thyroid...

We present an algorithm which splits a 3D surface into reliefs, relatively flat regions that have smooth boundaries. The surface is then resampled in a regular manner within each of the reliefs. As a result, we obtain a piecewise regular mesh (PRM), having a regular structure on large regions. Experimental results show that we are able to approximate the input surface with the mean square error...

Local polynomial regression LPR is applied to solve the partial differential equations PDEs . Usually, the solutions of the problems are separation of variables and eigenfunction expansion methods, so we are rarely able to find analytical solutions. Consequently, we must try to find numerical solutions. In this paper, two test problems are considered for the numerical illustration of the method...

A fundamental question for economics is why large firms in market economies usually assign control rights to capital suppliers rather than labor suppliers. A diverse collection of answers can be found in the literature. But unfortunately little theoretical consensus has emerged, and few attempts have been made to resolve this issue through systematic empirical investigation. This paper reviews ...
