The Game of Conservation

The Game of Conservation is a brilliantly crafted and highly readable examination of nature protection around the world. Twentieth-century nature conservation treaties often originated as attempts to regulate the pace of killing rather than as attempts to protect animal habitat. Some were prompted by major breakthroughs in firearm techniques, such as the invention of the elephant gun and grenade harpoons, but agricultural development was at least as important as hunting regulations in determining the fate of migratory species. The treaties had many defects, yet they also served the goal of conservation to good effect, often saving key species from complete extermination and sometimes keeping the population numbers at viable levels. It is because of these treaties that Africa is dotted with large national parks, that North America has an extensive network of bird refuges, and that there are any whales left in the oceans. All of these treaties are still in effect today, and all continue to influence nature-protection efforts around the globe. Drawing on a wide variety of primary and secondary sources, Mark Cioc shows that a handful of treaties—all designed to protect the world’s most commercially important migratory species—have largely shaped the contours of global nature conservation over the past century. The scope of the book ranges from the African savannahs and the skies of North America to the frigid waters of the Antarctic

Making Connections: Evaluation of a Professional Development Program for Teachers Focused on STEM Integration

This article reports on a 2-year evaluation of a STEM integration professional development (PD) program for 40 math, science, and special education teachers in Grades 5–9 from a large Midwestern public school district. The National Research Council’s framework for integrated STEM education (Honey, Pearson, & Schweingruber, 2014) was used to explain the goals, outcomes, nature and scope, and implementation of the program. Teachers were measured on their growth in STEM content knowledge, technology integration, teaching confidence, pedagogical beliefs, and impact of PD. Increases resulted in all these areas with statistically significant improvements in most of them, particularly in Year 2. A significant increase in math and science scores were also found in 413 students before and after participation in an integrated STEM lesson. According to teachers, the greatest strengths of the program were the STEM connections that teachers began making; the changes in teachers’ instructional practices; improved attitudes, beliefs, and confidence in teaching; increased comfort with using technology; and the enthusiasm that students exhibited during a STEM lesson. Quantitative data and teacher feedback both indicate that the program was highly successful and had a positive impact on teachers and students

Considerations regarding the Formulation of the Organisational Strategy through Simulation Techniques

The complexity, dimension and the scope of the economic problems specific to the correct development of organisational strategie require, on the one hand, the structuring and systematisation of their entire simulation activity in view of solving them. On the other hand, they require the adequacy of a relative independence resulted from the very nature of thinking, personality and professional education of those who wants to promote a certain type of organisational strategy. In other words, we can consider that the stages of creating a strategy simulation, although they are not compulsory, they cannot be entirely neglected, because there is minimum number of stages and sub-stages for which the optional character is not permitted. The entire decisional simulation cycle of a strategy obeys the three research levels: analysis, designing and management of the simulation activity.simulation; strategy; status of strategy; status of entropy; process.

First Impressions: Anglo Travelers and the Origins of El Paso, Texas, 1846-1852

El Paso del Norte was a thriving agricultural region on the Santa Fe-Chihuahua trail when the U.S.-Mexico War (1846-1848) and the 1849 gold rush turned it into a border town on the southern route to California. The diaries and letters of the Anglo-American soldiers, engineers, and gold seekers who passed through the area in the 1840s and 1850s document the emergence of a new political and economic landscape that helped define the pattern of Anglo-Mexican relations in the new town of El Paso, Texas (across the Rio Grande from El Paso del Norte), well into the next century

Vanillic acid and methoxyhydroquinone production from guaiacyl units and related aromatic compounds using Aspergillus niger cell factories

Background The aromatic compounds vanillin and vanillic acid are important fragrances used in the food, beverage, cosmetic and pharmaceutical industries. Currently, most aromatic compounds used in products are chemically synthesized, while only a small percentage is extracted from natural sources. The metabolism of vanillin and vanillic acid has been studied for decades in microorganisms and many studies have been conducted that showed that both can be produced from ferulic acid using bacteria. In contrast, the degradation of vanillin and vanillic acid by fungi is poorly studied and no genes involved in this metabolic pathway have been identified. In this study, we aimed to clarify this metabolic pathway in Aspergillus niger and identify the genes involved. Results Using whole-genome transcriptome data, four genes involved in vanillin and vanillic acid metabolism were identified. These include vanillin dehydrogenase (vdhA), vanillic acid hydroxylase (vhyA), and two genes encoding novel enzymes, which function as methoxyhydroquinone 1,2-dioxygenase (mhdA) and 4-oxo-monomethyl adipate esterase (omeA). Deletion of these genes in A. niger confirmed their role in aromatic metabolism and the enzymatic activities of these enzymes were verified. In addition, we demonstrated that mhdA and vhyA deletion mutants can be used as fungal cell factories for the accumulation of vanillic acid and methoxyhydroquinone from guaiacyl lignin units and related aromatic compounds. Conclusions This study provides new insights into the fungal aromatic metabolic pathways involved in the degradation of guaiacyl units and related aromatic compounds. The identification of the involved genes unlocks new potential for engineering aromatic compound-producing fungal cell factories.Peer reviewe
