Lead in Kentucky Soils

This study reviewed the literature on the occurrence of lead in soils and its relationship to waste oil tank leaks. Many studies have been conducted on the natural occurrence of lead in rocks, soils and water. Very low levels (0.001 mg/l to 0.01 mg/l) are found in surface and groundwater, variable levels are found in soils (from less that 10 ppm to as high as 700 ppm but more normally a high of 70 ppm), and the lead levels found in rocks range from 7 to 80 mg/kg. Risk assessment calculations have been made by several individuals, also with variable results. One value was computed at 20 mg/kg lead in soil and another was calculated as high as 200 mg/kg. A standard of 25 mg/kg is proposed for Kentucky based on the natural background level found in soils studied in the state. For sample values taken in tank pits that do not meet this standard a background value must be determined by taking 5 soil samples at one-meter depth upgradient from the tank pit and averaging them. Even though recommended cleanup level is not based on risk analysis methods, when referring to various risk documents, the value selected here is slightly lower than mean value (36 mg/kg) derived from an analysis of background samples at various remediation sites across the state. Standards in place in other states range from less than 0.1 mg/kg to as high as 2000 mg/kg. Texas uses 20 times the MCL, and Pennsylvania uses 200 ppm for the non-indiustrial sites and 600 ppm for industrial sites

Driving and sustaining culture change in professional sport performance teams: A grounded theory

Objectives As part of the recent upsurge of work on management and organizational factors in elite sports teams, researchers have focused on the team management-led creation and regulation of high performing cultures. The purpose of this study was to therefore add to a recently developed model of culture change best practice in Olympic sports teams, as led and perceived by incoming performance directors, and conceptualize culture change best practice in professional sports teams, as led and perceived by incoming team managers. Design and method A pragmatic research philosophy and corresponding grounded theory methodology were used to generate a practically-meaningful model of this culture change process from the perspective of UK-based professional team managers. Results Perceived best practice in team manager-led culture change was found to involve a finite phase of initial evaluation, planning, and impact adjoined to the enduring management of a holistic, integrated, and dynamic social system. With the former process acting as the catalyst for successful change, this model revealed that optimal change was felt to primarily rely on the constant acquisition, negotiation, and alignment of internal and external stakeholder perceptions. Conclusions Based on the model's principles, the optimization of professional team culture is defined by a manager's initial actions and never definitively achieved but rather constantly constructed and re-constructed in complex social and power dynamics. Beyond providing a conceptual backdrop for continued research in this area, the model is also a tool on which the practice of professional team managers and their supporting sport psychologists can be based

Take a walk on the wild side: Exploring, identifying, and developing consultancy expertise with elite performance team leaders

Objectives: Stemming from sport psychology’s recent shift to examine the effective management of elite sports team organizations, the extensive, significant, and complex challenges faced by those with responsibility for team performance have been emphasized. Recognizing that most work in this budding area has been theoretical in nature, our contribution to this special issue consequently identifies and critically evaluates some implications for excellence in practitioners who support leaders of elite sport performance teams. Method: Narrative review and commentary. Results and Conclusions: To survive and succeed, leaders of elite teams must: (a) negotiate complex and contested socio-political dynamics both within and outside their performance department; (b) make impactful and consistent real-time decisions; and (c) continually reinforce and protect their programme. To provide an optimally impactful and valued service, sport psychologists must therefore be able to advise on a broad and politically-astute leadership style and, most critically for consultancy excellence: (a) work within a professional judgment and decision making model; (b) facilitate the leader’s adaptive expertise and nested decision making; and (c) operate a proactive, forthright, and straight approach to ethical considerations. Based on these implications, we conclude by providing suggestions for the training and development of applied consultants

Mechanisms and advancement of antifading agents for fluorescence microscopy and single-molecule spectroscopy

Modern fluorescence microscopy applications go along with increasing demands for the employed fluorescent dyes. In this work, we compared antifading formulae utilizing a recently developed reducing and oxidizing system (ROXS) with commercial antifading agents. To systematically test fluorophore performance in fluorescence imaging of biological samples, we carried out photobleaching experiments using fixed cells labeled with various commonly used organic dyes, such as Alexa 488, Alexa 594, Alexa 647, Cy3B, ATTO 550, and ATTO 647N. Quantitative evaluation of (i) photostability, (ii) brightness, and (iii) storage stability of fluorophores in samples mounted in different antifades (AFs) reveal optimal combinations of dyes and AFs. Based on these results we provide guidance on which AF should preferably be used with a specific dye. Finally, we studied the antifading mechanisms of the commercial AFs using single-molecule spectroscopy and reveal that these empirically selected AFs exhibit similar properties to ROXS AFs

The illusion of competency versus the desirability of expertise: Seeking a common standard for support professions in sport

In this paper we examine and challenge the competency-based models which currently dominate accreditation and development systems in sport support disciplines, largely the sciences and coaching. Through consideration of exemplar shortcomings, the limitations of competency-based systems are presented as failing to cater for the complexity of decision making and the need for proactive experimentation essential to effective practice. To provide a better fit with the challenges of the various disciplines in their work with performers, an alternative approach is presented which focuses on the promotion, evaluation and elaboration of expertise. Such an approach resonates with important characteristics of professions, whilst also providing for the essential ‘shades of grey’ inherent in work with human participants. Key differences between the approaches are considered through exemplars of evaluation processes. The expertise-focused method, although inherently more complex, is seen as offering a less ambiguous and more positive route, both through more accurate representation of essential professional competence and through facilitation of future growth in proficiency and evolution of expertise in practice. Examples from the literature are also presented, offering further support for the practicalities of this approach

Culture change in elite sport performance teams: Examining and advancing effectiveness in the new era

Reflecting the importance of optimizing culture for elite teams, Fletcher and Arnold (2011) recently suggested the need for expertise in culture change. Acknowledging the dearth of literature on the specific process, however, the potential effectiveness of practitioners in this area is unknown. The present paper examines the activity's precise demands and the validity of understanding in sport psychology and organizational research to support its delivery. Recognizing that sport psychologists are being increasingly utilized by elite team management, initial evidence-based guidelines are presented. Finally, to stimulate the development of ecologically valid, practically meaningful knowledge, the paper identifies a number of future research directions

Report from the conference, ‘identifying obstacles to applying big data in agriculture’

Data-centric technology has not undergone widespread adoption in production agriculture but could address global needs for food security and farm profitability. Participants in the U.S. Department of Agriculture (USDA) National Institute for Food and Agriculture (NIFA) funded conference, “Identifying Obstacles to Applying Big Data in Agriculture,” held in Houston, TX, in August 2018, defined detailed scenarios in which on-farm decisions could benefit from the application of Big Data. The participants came from multiple academic fields, agricultural industries and government organizations and, in addition to defining the scenarios, they identified obstacles to implementing Big Data in these scenarios as well as potential solutions. This communication is a report on the conference and its outcomes. Two scenarios are included to represent the overall key findings in commonly identified obstacles and solutions: “In-season yield prediction for real-time decision-making”, and “Sow lameness.” Common obstacles identified at the conference included error in the data, inaccessibility of the data, unusability of the data, incompatibility of data generation and processing systems, the inconvenience of handling the data, the lack of a clear return on investment (ROI) and unclear ownership. Less common but valuable solutions to common obstacles are also noted

Ground Support Software for Spaceborne Instrumentation

ION is a system of ground support software for the ion and neutral mass spectrometer (INMS) instrument aboard the Cassini spacecraft. By incorporating commercial off-the-shelf database, Web server, and Java application components, ION offers considerably more ground-support-service capability than was available previously. A member of the team that operates the INMS or a scientist who uses the data collected by the INMS can gain access to most of the services provided by ION via a standard pointand click hyperlink interface generated by almost any Web-browser program running in almost any operating system on almost any computer. Data are stored in one central location in a relational database in a non-proprietary format, are accessible in many combinations and formats, and can be combined with data from other instruments and spacecraft. The use of the Java programming language as a system-interface language offers numerous capabilities for object-oriented programming and for making the database accessible to participants using a variety of computer hardware and software
