    This sequential, fixed, mixed-methods study explores how mindfulness practice by leaders in higher education social work programs influences the leader-employee relationship among a sample of higher education social work department leaders and their faculty. This study was developed out of the intersection of personal, professional, and academic interests in both mindfulness and leadership. Additionally, this study fills a gap in the existing literature on how leaders’ individual mindfulness practice influences the relationship between them and their employees (Reb et al., 2019; Rooney et al., 2021; Urrila, 2021). The results of this study were that the sample of social work higher education leaders reported an average Mindfulness and Attention Awareness Scale score of 4.16 (out of 6) which indicates a higher than mid-range trait mindfulness but lower than the normative average of 4.2 (Brown & Ryan, 2003). Faculty averaged 5. The results of this study were that the sample of social work higher education leaders reported an average Mindfulness and Attention Awareness Scale score of 4.16 (out of 6) which indicates a higher than mid-range trait mindfulness but lower than the normative average of 4.2 (Brown & Ryan, 2003). Faculty averaged 5.24 (out of 7)on the Multidimensionality of Leader Member Exchange scale (Liden & Maslyn, 1998), which indicates that social work faculty have a higher than mid-range relationships with their leaders. In a comparative analysis, it does indicate that there is a positive correlation between a leader’s overall trait mindfulness and how employees rate that relationship. Additionally, the qualitative elements showed that leaders who practiced mindfulness felt that they developed more self awareness which allowed them to better be able to build relationships with employees, and that employees found that communication, workplace culture, support, positionality, and the type of leader are crucial elements in developing their relationships with their employees. One groupset showed that a leader’s routine practice could positively impact the leader-faculty relationship. This study’s findings do indicate that leader mindfulness does positively impact the leader-member relationship, and that routine practice could enhance the relationship even further. These outcomes can be used to support higher education institutions adding mindfulness elements into their leader trainings and development, and encourage leaders to cultivate mindfulness on their own

    Millions of Americans suffer from foodborne illnesses each year. While mild cases often get shrugged off after spending a night in the bathroom, a small number of people suffer drastic consequences for liking their burgers medium rare. Consumers take for granted, and are reassured by, the presence of a “USDA inspected” sticker on their meat products. Part I of this Note reviews the history of federal regulation of the beef industry, discusses the particular dangers of Escherichia coli 0157:57 (“E. coli O157:H7”) as a foodborne pathogen, outlines the inspection systems implemented in response to outbreaks of E. coli O157:H7 outbreaks, and explains current recall practices for potentially contaminated products. Part II analyzes the shortcomings of the current regulatory framework for ground beef inspections and the ability of the beef industry to “pass the buck” when contaminated beef products make their way out to the public. Part III proposes legislation that would grant the government the ability to mandate recalls of contaminated products and to fine those companies who do not properly inspect their products or maintain sanitary processing facilities

    A series of ortho-substituted arylchlorophosphoranes has been prepared. The structures of these compounds have been studied by the use of (^31)Cl n.q.r. and solid-state (^31)P n.m.r. . It has been shown that ortho substitution by groups such as CH(_3) or CF(_3) in phosphoranes of the type P(Ar)Cl4 prevents complexation with Lewis bases, and this is also found to be the case for the derived phosphoniumions [P(Ar)Cl(_3)](^+). The bis(aryl)chlorophosphoranes with these bulky aryl groups (where it is possible for them to be formed) are found to have ionic phosphonium salt structures, regardless of the electronic properties of the aryl group. In some cases, where the aryl groups are too bulky and too electronegative, P-C bond cleavage takes place on chlorination of the bis(aryl)chlorophosphine, and the most bulky group is lost. The phosphoranes PRCl(_4) (where R = CH(_2)Cl or CHCl(_2)) were also prepared. For R = CH(_2)Cl, the solid phosphorane was found to have the ionic, [PRCl(_3)] [PRCl(_5)], structure. This is the first example of an organo-substituted chlorophosphorane to be shown to have the "phosphorus pentachloride structure” in the solid state. By contrast, P(CHCl(_2))Cl(_4) was shown by solid-state (^31)P n.m.r. to be a molecular, 5-coordinate species. The generation of phosphoranides of the type [P(Ar)(CN)(_2)X](^-), with ortho- substituted aryl substituents, has also been investigated. From (^31)P n.m.r. it has been shown that the 2-(methyl)phenyl group can be incorporated into such systems. Various aryl- and aryloxy-1,3,2-dioxaphospholanes were prepared, with the aim of generating metaphosphate species via ethylene elimination. Data from mass spectrometry and from flow pyrolysis suggest that transient metaphosphates of the type ArPO(_2) can be formed in this manner. Results would also indicate that where Ar = 2,6-(CF(_3))(_2)C(_6)H(_3) the respective metaphosphate undergoes a rearrangement via insertion into the ortho-CF(_3) group. It has been shown that the symmetrical diphosphene ArP=PAr (where Ar - 2,4,6-(CF(_3))(_3)C(_6)H(_2)) can be formed by magnesium couphng of the aryldichloro- phosphine. However, attempts to form asymmetrical diphosphines and other low- coordinate phosphorus species by DBU coupling of P(2,6-(CF(_3))(_2)C(_6)H(_3))H(_2) with the respective chloro species were unsuccessful, due to preferred formation of Ar(H)P- P(H)Ar or ArP=PAr. The 2,4,6-(CF(_3))(_3)C(_6)H(_2) group was successfully incorporated into various dia- zophosphine systems. Of particular note was the characterization of the first ever P(III)-P(III) stabilized nit rile imine. By varying the aryl groups on phosphorus in such systems (C(_6)H(_5), C(_6)F(_5) or 2,4,6-(CF(_3))(_3)C(_6)H(_2)) it was possible to obtain further insights into the requirements for the stabilization of nitrile imines, and various trapping reaction were also performed

    Mechatronic Camera Operator: Final Design Report

    Get PDF
    A mechatronic system is designed, constructed, and tested to aid filmmakers in the movement and control of a video camera. The system design allows for 6-DOF camera movement (movement in all three spatial directions, pan, tilt, and roll). The system is controlled by a human operator, using an implementation of a gamepad controller, and the system is battery-powered; the theoretical range of the system is therefore limited only by the onboard battery power, and the operator’s ability to keep within cord-length of the system as it moves. A misallocation of time resources resulted in an incomplete physical design, but preliminary testing indicates that the design is sound, and that mechanical specifications are sufficiently robust for a working final system. Further time and resources would be used to complete physical construction and electronic implementation, and to implement a feedback system to allow for closed-loop actuator control and the function of repeatable motio

    Teachers with training in special education are found in most schools. Why are some special education teachers teaching students in a \u27pull-out\u27. model while others are teaching in a \u27push-in\u27 model? For those students who are pushed in , are they supported in the classroom? And if so, how? If it is by a co-teaching model, what is the most beneficial way of teaching special education students in a general education classroom? What are some of the attitudes of special education students who are pushed into a co-teaching classroom

    Summary 1. Significant advances in both mathematical and molecular approaches in ecology offer unprecedented opportunities to describe and understand ecosystem functioning. Ecological networks describe interactions between species, the underlying structure of communities and the function and stability of ecosystems. They provide the ability to assess the robustness of complex ecological communities to species loss, as well as a novel way of guiding restoration. However, empirically quantifying the interactions between entire communities remains a significant challenge. 2. Concomitantly, advances in DNA sequencing technologies are resolving previously intractable questions in functional and taxonomic biodiversity and provide enormous potential to determine hitherto difficult to observe species interactions. Combining DNA metabarcoding approaches with ecological network analysis presents important new opportunities for understanding large-scale ecological and evolutionary processes, as well as providing powerful tools for building ecosystems that are resilient to environmental change. 3. We propose a novel ‘nested tagging’ metabarcoding approach for the rapid construction of large, phylogenetically structured species-interaction networks. Taking tree–insect–parasitoid ecological networks as an illustration, we show how measures of network robustness, constructed using DNA metabarcoding, can be used to determine the consequences of tree species loss within forests, and forest habitat loss within wider landscapes. By determining which species and habitats are important to network integrity, we propose new directions for forest management. 4. Merging metabarcoding with ecological network analysis provides a revolutionary opportunity to construct some of the largest, phylogenetically structured species-interaction networks to date, providing new ways to: (i) monitor biodiversity and ecosystem functioning; (ii) assess the robustness of interacting communities to species loss; and (iii) build ecosystems that are more resilient to environmental change

    A histidine residue and a tetranuclear cuprous‐thiolate cluster dominate the copper loading landscape of a copper storage protein from Streptomyces lividans

    The chemical basis for protecting organisms against the toxic effect imposed by excess cuprous ions is to constrain this through high‐affinity binding sites that use cuprous‐thiolate coordination chemistry. In bacteria, a family of cysteine rich four‐helix bundle proteins utilise thiolate chemistry to bind up to 80 cuprous ions. These proteins have been termed copper storage proteins (Csp). The present study investigates cuprous ion loading to the Csp from Streptomyces lividans (SlCsp) using a combination of X‐ray crystallography, site‐directed mutagenesis and stopped‐flow reaction kinetics with either aquatic cuprous ions or a chelating donor. We illustrate that at low cuprous ion concentrations, copper is loaded exclusively into an outer core region of SlCsp via one end of the four‐helix bundle, facilitated by a set of three histidine residues. X‐ray crystallography reveals the existence of polynuclear cuprous‐thiolate clusters culminating in the assembly of a tetranuclear [Cu4(ÎŒ2‐S‐Cys)4(ΝΎ1‐His)] cluster in the outer core. As more cuprous ions are loaded, the cysteine lined inner core of SlCsp fills with cuprous ions but in a fluxional and dynamic manner with no evidence for the assembly of further intermediate polynuclear cuprous‐thiolate clusters as observed in the outer core. Using site‐directed mutagenesis a key role for His107 in the efficient loading of cuprous ions from a donor is established. A model of copper loading to SlCsp is proposed and discussed
