The Sonic Hedgehog Pathway Stimulates Prostate Tumor Growth by Paracrine Signaling and Recaptures Embryonic Gene Expression in Tumor Myofibroblasts
The Hedgehog (Hh) pathway contributes to prostate cancer growth and progression. The presence of robust Shh expression in both normal prostate and localized cancer challenged us to explain the unique growth promoting effect in cancer. We show here that paracrine Hh signaling exerts a non-cell autonomous effect on xenograft tumor growth and that Hh pathway activation in myofibroblasts alone is sufficient to stimulate tumor growth. Nine genes regulated by Hh in the mesenchyme of the developing prostate were found to be regulated in the stroma of Hh over-expressing xenograft tumors. Correlation analysis of gene expression in matched specimens of benign and malignant human prostate tissue revealed a partial 5 gene fingerprint of Hh-regulated expression in stroma of all cancers and the complete 9 gene fingerprint in the subset of tumors exhibiting a reactive stroma. No expression fingerprint was observed in benign tissues. We conclude that changes in the prostate stroma due to association with cancer result in an altered transcriptional response to Hh that mimics the growth promoting actions of the fetal mesenchyme. Patients with an abundance of myofibroblasts in biopsy tissue may comprise a sub-group that will exhibit a particularly good response to anti-Hedgehog therapy
Development and Validation of the Single Item Trait Empathy Scale (SITES)
Empathy involves feeling compassion for others and imagining how they feel. In this article, we develop and validate the Single Item Trait Empathy Scale (SITES), which contains only one item that takes seconds to complete. In seven studies (N = 5724), the SITES was found to be both reliable and valid. It correlated in expected ways with a wide variety of intrapersonal outcomes. For example, it is negatively correlated with narcissism, depression, anxiety, and alexithymia. In contrast, it is positively correlated with other measures of empathy, self-esteem, subjective well-being, and agreeableness. The SITES also correlates with a wide variety of interpersonal outcomes, especially compassion for others and helping others. The SITES is recommended in situations when time or question quantity is constrained
Transparency, financial accounting information, and corporate governance
Audited financial statements along with supporting disclosures form the foundation of the firm-specific information set available to investors and regulators. In this article, the authors discuss economics-based research focused on the properties of accounting systems and the surrounding institutional environment important to effective governance of firms. They provide a framework for understanding the operation of accounting information in an economy, discuss a broad range of important research findings, present a conceptual framework for characterizing and measuring corporate transparency at the country level, and isolate a number of future research possibilities.Corporations - Accounting ; Stockholders ; Corporate governance
Development and Validation of the Single Item Narcissism Scale (SINS)
Main Objectives: The narcissistic personality is characterized by grandiosity, entitlement, and low empathy. This paper describes the development and validation of the Single Item Narcissism Scale (SINS). Although the use of longer instruments is superior in most circumstances, we recommend the SINS in some circumstances (e.g. under serious time constraints, online studies).
Methods: In 11 independent studies (total N = 2,250), we demonstrate the SINS\u27 psychometric properties.
Results: The SINS is significantly correlated with longer narcissism scales, but uncorrelated with self-esteem. It also has high test-retest reliability. We validate the SINS in a variety of samples (e.g., undergraduates, nationally representative adults), intrapersonal correlates (e.g., positive affect, depression), and interpersonal correlates (e.g., aggression, relationship quality, prosocial behavior). The SINS taps into the more fragile and less desirable components of narcissism.
Significance: The SINS can be a useful tool for researchers, especially when it is important to measure narcissism with constraints preventing the use of longer measures
The Archive of Restoration Culture, 1997-2002
When I first began work on Joseph Smith: Rough Stone Rolling in 1996, I realized that reconstructing the cultural environment of the Prophet would be one of my largest tasks. I could scarcely conceive how to go about probing the huge quantities of sermons, newspapers, journals, pamphlets, books, artworks, and private diaries that possibly bore on the restoration of the gospel in the 1820s through the 1840s. Yet the culture of that period bore directly on the success of the young church under Joseph Smith’s leadership. People would never be able to grasp theological ideas that were entirely foreign to them. They would need a basic preparation for the Prophet’s revelations, making the cultural environment crucial to understanding how the Restoration came about.
Faced with this apparently insuperable difficulty, it occurred to me that my problem was the problem of every historian interested in early history of the Church. We all need information about the sources as they relate to the distinctive doctrines of the Restoration. I would deal with many of the issues in my biography, but subsequent researchers would think of new questions about Joseph’s times. All of these historians would benefit from a collection of materials from the world in which Joseph Smith flourished.
So was born the concept of “The Archive of Restoration Culture,” an assemblage of source materials illuminating contemporaneous thought about the prominent principles of the Restoration. I am pleased now, a decade later, that this massive research database is now available on the BYU Studies website
The Character of Joseph Smith
The title of this essay, The Character of Joseph Smith, may promise more than can ever be fulfilled. Joseph warned the Saints of the difficulty in trying to understand him. In the King Follett discourse given two months before his death, he told them, You don\u27t know me--you never will. Another version of the same speech says, You never knew my heart. No man knows my hist[ory]. He seems to say that what we want to know most--his heart and his history--are not to be found out. No matter how much we study him, we must be cautious about believing we have comprehended him. There is too much there, and much of it is far beyond the ordinary. As he continues, I don\u27t blame you for not believing my history had I not expected it [I] could not believe it myself
Treasure-seeking Then and Now
Last August I attended the BYU conference on the Mark Hofmann documents where I had an opportunity to reflect on what the documents meant to me. After searching my thoughts and testing my feelings, I came to the conclusion that they meant very little. They did not mean much when they first came out, and their fall from historical authenticity had little effect on me later. That may sound like a strange confession from one who was writing on the early life of Joseph Smith at the very moment the Salamander and 1825 Joseph Smith letters came to light, with their presumably earthshaking revelations about Joseph Smith’s money-digging. Yet it is true
Joseph Smith’s Many Histories
I wish to explore, in broad general terms, the histories to which historians have attached Joseph Smith. As you can imagine, the context in which he is placed profoundly affects how people see the Prophet, since the history selected for a subject colors everything about it. Is he a money-digger like hundreds of other superstitious Yankees in his day, a religious fanatic like Muhammad was thought to be in Joseph’s time, a prophet like Moses, a religious revolutionary like Jesus? To a large extent, Joseph Smith assumes the character of the history selected for him. The broader the historical context, the greater the appreciation of the man. If Joseph Smith is described as the product of strictly local circumstances—the culture of the Burned-over District, for example—he will be considered a lesser figure than if put in the context of Muhammad or Moses. Historians who have been impressed with Joseph Smith’s potency, whether for good or ill, have located him in a longer, more universal history. Those who see him as merely a colorful character go no farther than his immediate environment for context. No historians eliminate the local from their explanations, but, on the whole, those who value his genius or his influence, whether critics or believers, give him a broader history as well. I want to talk first about the way historians have sought the Prophet’s larger meaning by assigning him a history, and then examine the histories to which Joseph Smith attached himself
Was Joseph Smith a Gentleman? The Standard for Refinement in Utah
The question of refinement cut even more deeply in Utah in the early days when the governance of the territory was at issue. The Latter-day Saints worked with a double handicap in striving to win respect from eastern travelers: in addition to the usual doubts about civilization in the West, the visitors were skeptical about Mormon religious fanaticism. Travelers came expecting that the poor credulous fools who submitted to the rule of Brigham Young would lack education, manners, taste, and intelligence—in short,would be as degraded as the woodcutters Trollope sighted along the banks of the Mississippi. The Saints for their part had a lot at stake in proving the travelers wrong. If they could not persuade visitors of their religious beliefs, the Mormons at least wanted to demonstrate their refinement.Besides respect from eastern cultural centers, control over their government hung in the balance
