Collectivism and Individualism in a Professionalism Study of Public Relations Practitioners and Journalists

The adversarial relationship between journalists and public relations practitioners is nothing new. No matter in what era or in what context, there has always been friction between those who mind the media gates and those whose livelihoods depend upon getting information disseminated. It is inherent, it is argued here, for cultural discourse of public relations practitioners and journalists. Several studies examined the adversarial relationship, and most had consistent findings -- the two occupations view each other quite differently. Stegall and Sanders (1986) indicated that journalists see their roles and the roles of public relations practitioners as distinctly different. They wrote that journalists believe they have a responsibility to be the public\u27s eyes and ears, while thinking of public relations people as promoters, not journalists. Journalists expect public relations persons to show only the positive elements of their clients or organizations and shield the negative aspects. Stegall and Sanders summarized their thoughts this way: The reporter thinks his own motivations are more honorable_than those of the public relations director (p. 343). Tunstall (1971) explained that journalists see themselves above reproach and the crass commercialism (p. 72) of public relations practitioners

Examining Share Lease Arrangements for Grain Operations in the Texas Panhandle Under Changing Market Conditions

This paper examines the preferred share arrangement for both landlords and tenants producing grain in the Texas High Plains (based on risk preference), and determines the sensitivity to changing input costs and market prices. Results of the analyses show that tenants and landlords prefer different arrangements in all scenarios. Results also indicate that a tenant would prefer a different lease arrangement in 2008 than in 2005, while the landlord’s preference would remain unchanged.Financial Economics, Production Economics,

Short-term Response of Holcus lanatus L. (Common Velvetgrass) to Chemical and Manual Control at Yosemite National Park, USA

One of the highest priority invasive species at both Yosemite and Sequoia and Kings Canyon national parks is Holcus lanatus L. (common velvetgrass), a perennial bunchgrass that invades mid-elevation montane meadows. Despite velvetgrass being a high priority species, there is little information available on control techniques. The goal of this project was to evaluate the short-term response of a single application of common chemical and manual velvetgrass control techniques. The study was conducted at three montane sites in Yosemite National Park. Glyphosate spotspray treatments were applied at 0.5, 1.0, 1.5, and 2.0% concentrations, and compared with hand pulling to evaluate effects on cover of common velvetgrass, cover of other plant species, and community species richness. Posttreatment year 1 cover of common velvetgrass was 12.1% 6 1.6 in control plots, 6.3% 6 1.5 averaged over the four chemical treatments (all chemical treatments performed similarly), and 13.6% 6 1.7 for handpulled plots. This represents an approximately 50% reduction in common velvetgrass cover in chemically- treated plots recoded posttreatment year 1 and no statistically significant reduction in hand pulled plots compared with controls. However, there was no treatment effect in posttreatment year 2, and all herbicide application rates performed similarly. In addition, there were no significant treatment effects on nontarget species or species richness. These results suggest that for this level of infestation and habitat type, (1) one year of hand pulling is not an effective control method and (2) glyphosate provides some level of control in the short-term without impact to nontarget plant species, but the effect is temporary as a single year of glyphosate treatment is ineffective over a twoyear period

Straw and Nominee Corporations in Real Estate Tax Shelter Transactions

During 1976, Congress placed some severe restrictions on tax shelter investments. In addition, even before Congress acted, the Internal Revenue Service (IRS) initiated its own attack on tax shelters. One IRS tactic to frustrate the objectives of tax shelter investments is to shift the incidence of taxation from one entity to another. This Article focuses primarily on one phase of the IRS attacks on real estate tax shelters. We will explore the history and legal foundation of the IRS’s present position, outline alternative arguments that can be raised by a real taxpayer involved in an IRS audit, and suggest possible tax planning considerations

CLASSIFICATION OF EXPLOSIVES TRANSFORMATION PRODUCTS IN PLANT TISSUE

Explosives contamination in surface or groundwater used for the irrigation of food crops and phytoremediation of explosives-contaminated soil or water using plant-assisted biodegradation have brought about concerns as to the fate of explosives in plants. Liquid scintillation counting, high-performance liquid chromatography, and gel permeation chromatography were utilized to characterize explosives (hexahydro-1,3,5-trinitro-1,3,5-triazine and trinitrotoluene) and their metabolites in plant tissues obtained from three separate studies. Analyzing tissues of yellow nutsedge (Cyperus esculentus), corn (Zea mays), lettuce (Lacuta sativa), tomato (Lyopersicum esculentum), radish (Raphanus sativus), and parrot feather (Myriophyllum aquaticum) from three studies where exposure to explosives at nontoxic levels (1–2 mg/L in water) occurred showed that extensive transformation of the explosive contaminant occurred, variations were noted in uptake and transformation between terrestrial and aquatic plants, the products had significantly higher polarity and water solubility than the parent compounds, and the molecular sizes of the transformation products were significantly greater than those of the parent compounds (approximately 300 times greater)

A brain-derived MeCP2 complex supports a role for MeCP2 in RNA processing

Mutations in MECP2 (methyl-CpG-binding protein 2) are linked to the severe postnatal neurodevelopmental disorder RTT (Rett syndrome). MeCP2 was originally characterized as a transcriptional repressor that preferentially bound methylated DNA; however, recent results indicate MeCP2 is a multifunctional protein. MeCP2 binding is now associated with certain expressed genes and involved in nuclear organization as well, indicating that its gene regulatory function is context-dependent. In addition, MeCP2 is proposed to regulate mRNA splicing and a mouse model for RTT shows aberrant mRNA splicing. To further understand MeCP2 and potential roles in RTT pathogenesis, we have employed a biochemical approach to identify the MeCP2 protein complexes present in the mammalian brain. We show that MeCP2 exists in at least four biochemically distinct pools in the brain and characterize one novel brain-derived MeCP2 complex that contains the splicing factor Prpf3 (pre-mRNA processing factor 3). MeCP2 directly interacts with Prpf3 in vitro and in vivo and many MECP2 RTT truncations disrupt the MeCP2-Prpf3 complex. In addition, MeCP2 and Prpf3 associate in vivo with mRNAs from genes known to be expressed when their promoters are associated with MeCP2. These results support a role for MeCP2 in mRNA biogenesis and suggest an additional mechanism for RTT pathophysiology
