The Australian Feral Camel Management Project (AFCMP) was initiated in 2009 to manage the growing impacts of feral camels (Camelus dromedarius) in Australia. One of the most important considerations for the project was achieving high standards of animal welfare and demonstrating this to stakeholders and the public. The novelty of feral camels as an invasive species meant that relatively little was known about the animal welfare aspects of the available management techniques. To address this knowledge gap, quantitative animal-based assessment tools were developed to allow independent observers to perform repeatable in situ field auditing of the two main control methods used: aerial (helicopter) shooting and live capture (mustering and transport for slaughter). Although observation protocols allowed most stages of aerial shooting (in situ killing) to be assessed, not all stages of live capture operations could be assessed (namely transport and slaughter at ex situ abattoirs) due to the limitations of the jurisdiction of the Australian Feral Camel Management Project. For assessments that were performed, audit results were made available to project partners to allow procedures to be reviewed and published through peer-reviewed literature to improve transparency. Empirical evidence produced through the audit system was also used to refine humaneness ranking assessments comparing management methods. We present the lessons learnt through the animal welfare approach of the AFCMP to assist future wild herbivore management programs.

Abstract Engage, educate and raise public awareness of the importance of plant diversity is the means through which plant conservation can be achieved. The Global Strategy for Plant Conservation (GSPC) is a programme to halt the loss of plant diversity and recognize botanical gardens as a partners. This paper investigates the implementation of targets 14 and 15 GSPC in Brazilian botanic gardens specially in education and awareness about plant diversity and trained people. A survey was carried out on the institutional websites of 21 gardens registered in the National System of Botanical Gardens Registration to identify actions that follow the guidelines of these two targets. Websites outdated, difficult access and lack online resources for the public shows us that internet tools are poorly used to divulgation. The target 14's activities performed in most gardens are educational visits and environmental interpretation and explore collections in situ and ex situ from representative species of regional flora. Trained people is held in all gardens but some stand out as important research centers and graduate programs. Despite the efforts Brazilian botanical gardens need improve the public communication and develop strategies to measure the targets progress.

The US spends far more than any other nation on health care. Physicians undergo lengthy and comprehensive training that is carefully scrutinized, and are held to high standards in national examinations. At best the care delivered matches or exceeds that in any other country. And yet, often simple preventable medical errors occur at alarming and unacceptable rates. The public, corporate consumers of health care, large payors and malpractice insurance carriers are all becoming impatient with the pace of improvement. The medical profession recognizes that dealing with this problem is an urgent priority and is grappling to find the best approaches. This paper focuses on the constructive use of assessment to embed a pervasive and proactive culture of patient safety into practice, starting with the trainee and extending out into the practice years. This strategy is based on the adage that “assessment drives curriculum” and proposes a series of new assessment tools to be added to all phases of the training-practice continuum.

The cobalt disilicide/silicon system has potential applications as a metal-base and as a permeable-base transistor. Although thin, low defect density, films of CoSi2 on Si(111) have been successfully grown, there are reasons to believe that Si(100)/CoSi2 may be better suited to the transmission of electrons at the silicon/silicide interface than Si(111)/CoSi2. A TEM study of the formation of CoSi2 on Si(100) is therefore being conducted. We have previously reported TEM observations on Si(111)/CoSi2 grown both in situ, in an ultra high vacuum (UHV) TEM and ex situ, in a conventional Molecular Beam Epitaxy system.The procedures used for the MBE growth have been described elsewhere. In situ experiments were performed in a JEOL 200CX electron microscope, extensively modified to give a vacuum of better than 10-9 T in the specimen region and the capacity to do in situ sample heating and deposition. Cobalt was deposited onto clean Si(100) samples by thermal evaporation from cobalt-coated Ta filaments.

Generally, processing of thin films involves several annealing steps in addition to the deposition step. During the annealing steps, diffusion, transformations and reactions take place. In this paper, examples of the use of TEM and AEM for ex situ and in situ studies of reactions and phase transformations in thin films will be presented.The ex situ studies were carried out on Nb/Al multilayer thin films annealed to different stages of reaction. Figure 1 shows a multilayer with dNb = 383 and dAl = 117 nm annealed at 750°C for 4 hours. As can be seen in the micrograph, there are four phases, Nb/Nb3-xAl/Nb2-xAl/NbAl3, present in the film at this stage of the reaction. The composition of each of the four regions marked 1-4 was obtained by EDX analysis. The absolute concentration in each region could not be determined due to the lack of thickness and geometry parameters that were required to make the necessary absorption and fluorescence corrections.

The silicides CoSi2 and NiSi2 are both metallic with the fee flourite structure and lattice constants which are close to silicon (1.2% and 0.6% smaller at room temperature respectively) Consequently epitaxial cobalt and nickel disilicide can be grown on silicon. If these layers are formed by ultra high vacuum (UHV) deposition (also known as molecular beam epitaxy or MBE) their thickness can be controlled to within a few monolayers. Such ultrathin metal/silicon systems have many potential applications: for example electronic devices based on ballistic transport. They also provide a model system to study the properties of heterointerfaces. In this work we will discuss results obtained using in situ and ex situ transmission electron microscopy (TEM).In situ TEM is suited to the study of MBE growth for several reasons. It offers high spatial resolution and the ability to penetrate many monolayers of material. This is in contrast to the techniques which are usually employed for in situ measurements in MBE, for example low energy electron diffraction (LEED) and reflection high energy electron diffraction (RHEED), which are both sensitive to only a few monolayers at the surface.

<div>Atomic layer deposition (ALD) of LiF and lithium ion conducting (AlF<sub>3</sub>)(LiF)<sub>x</sub> alloys was developed using trimethylaluminum, lithium hexamethyldisilazide (LiHMDS) and hydrogen fluoride derived from HF-pyridine solution. ALD of LiF was studied using in situ quartz crystal microbalance (QCM) and in situ quadrupole mass spectrometer (QMS) at reaction temperatures between 125°C and 250°C. A mass gain per cycle of 12 ng/(cm<sup>2</sup> cycle) was obtained from QCM measurements at 150°C and decreased at higher temperatures. QMS detected FSi(CH<sub>3</sub>)<sub>3</sub> as a reaction byproduct instead of HMDS at 150°C. LiF ALD showed self-limiting behavior. Ex situ measurements using X-ray reflectivity (XRR) and spectroscopic ellipsometry (SE) showed a growth rate of 0.5-0.6 Å/cycle, in good agreement with the in situ QCM measurements.</div><div>ALD of lithium ion conducting (AlF3)(LiF)x alloys was also demonstrated using in situ QCM and in situ QMS at reaction temperatures at 150°C A mass gain per sequence of 22 ng/(cm<sup>2</sup> cycle) was obtained from QCM measurements at 150°C. Ex situ measurements using XRR and SE showed a linear growth rate of 0.9 Å/sequence, in good agreement with the in situ QCM measurements. Stoichiometry between AlF<sub>3</sub> and LiF by QCM experiment was calculated to 1:2.8. XPS showed LiF film consist of lithium and fluorine. XPS also showed (AlF<sub>3</sub>)(LiF)x alloy consists of aluminum, lithium and fluorine. Carbon, oxygen, and nitrogen impurities were both below the detection limit of XPS. Grazing incidence X-ray diffraction (GIXRD) observed that LiF and (AlF<sub>3</sub>)(LiF)<sub>x</sub> alloy film have crystalline structures. Inductively coupled plasma mass spectrometry (ICP-MS) and ionic chromatography revealed atomic ratio of Li:F=1:1.1 and Al:Li:F=1:2.7: 5.4 for (AlF<sub>3</sub>)(LiF)<sub>x</sub> alloy film. These atomic ratios were consistent with the calculation from QCM experiments. Finally, lithium ion conductivity (AlF<sub>3</sub>)(LiF)<sub>x</sub> alloy film was measured as σ = 7.5 × 10<sup>-6</sup> S/cm.</div>

Aim/Purpose: The purpose of this study is to examine tough-love mentoring theory (TLM) as a potential way to address the problem of low graduation rates among doctoral students. Background: In order to address this purpose, the researcher presents the following: a) a validation study for assessment tools pertaining to TLM and b) a validation study of TLM theory and its two sub-theories: mentor integrity and trustworthiness sub-theory (MIT) and the mentor high standards sub-theory (MHS). Methodology: The researcher tested the validity of the mentor integrity and trustworthiness scale from the protégés’ perspective (MIT-P), the mentor high standards scale from the protégés’ perspective (MHS-P) and the protégés’ perceptions of their own independence (PPI) scale. The sample consisted of 31 doctoral protégés recruited with multi-phase sampling at four education-related doctoral programs in the eastern part of the United States. Contribution: The study provides evidence to support TLM as a strategy to address the problem of low graduation rates among doctoral students. In addition, the study contributes validation of assessment tools that can be used to measure doctoral protégés’ perceptions of their mentors. Findings: For each scale, the data show acceptable levels of internal consistency and evidence of content validity. The data are consistent with the TLM theory and its two sub-theories. The unique contribution of the current study is that it draws from the protégés’ perspective. Recommendations for Practitioners: The researcher presents a) strategies protégés can use to find trustworthy mentors with high standards and b) strategies program administrators can use for professional development of doctoral mentors. The researcher also provides the Right Angle Research Alignment (RARA) table to help protégés organize and manage the research methods section of their dissertation. Recommendation for Researchers: It is recommended that researchers use experimental methods to test TLM theory and the sub-theories, MIT and MHS. Impact on Society: This theory may be useful in business and in the arts and in other teaching relationships such as coaching and tutoring. The researcher encourages scholars to test TLM theory in these other contexts. Future Research: Further research questions that arise from this study are as follows: How can protégés find mentors who have high standards and who are trustworthy? What can doctoral program administrators do to help mentors develop high standards and trustworthiness?

Abstract Cross-sectional style transmission electron microscopy (TEM) sample preparation techniques by DualBeam (SEM/FIB) systems are widely used in both laboratory and manufacturing lines with either in-situ or ex-situ lift out methods. By contrast, however, the plan view TEM sample has only been prepared in the laboratory environment, and only after breaking the wafer. This paper introduces a novel methodology for in-line, plan view TEM sample preparation at the 300mm wafer level that does not require breaking the wafer. It also presents the benefit of the technique on electrically short defects. The methodology of thin lamella TEM sample preparation for plan view work in two different tool configurations is also presented. The detailed procedure of thin lamella sample preparation is also described. In-line, full wafer plan view (S)TEM provides a quick turn around solution for defect analysis in the manufacturing line.

Picea mexicana Martínez, P. chihuahuana Martínez y P. martinezii Patterson son especies endémicas de México en peligro de extinción. Se presenta una síntesis de su situación actual y una propuesta de manejo para su conservación in situ y ex situ, con base en la diversidad y estructura genética de las poblaciones y la ubicación de las áreas en donde se predice existirá el hábitat climático que les es propicio en el futuro (años 2030, 2060 y 2090; al promediar los modelos Canadiense, Hadley y Geofísica de Fluidos con escenarios de emisiones A y B). Para la conservación in situ se plantea la protección, el incremento de la diversidad genética y la expansión de las tres únicas poblaciones de P. mexicana, las cuatro únicas de P. martinezii y ocho poblaciones designadas prioritarias de las 40 poblaciones de P. chihuahuana, mediante la plantación de individuos originados de otras poblaciones hasta alcanzar un tamaño mínimo de población genéticamente viable (entre 1035 a 3836 individuos). Para la conservación ex situ se propone el establecimiento de poblaciones en sitios fuera del rango de distribución natural de las especies, en donde se ha proyectado que ocurrirá el clima que les es propicio, con al menos 3606 individuos de P. mexicana en el volcán Cofre de Perote, Veracruz; 2431 individuos de P. chihuahuana en el municipio de Guanaceví, Durango; y 3092 individuos de P. martinezii en la región de Tlatlauquitepec, Puebla, con plantas originadas de una mezcla de semillas colectadas de árboles al azar de poblaciones específicas.
