Full textAbstract:
Focusing on two painted Pietàs, this essay examines the means by which the artists Giulio Clovio (1498–1578) and Sebastiano del Piombo (1485–1547) simultaneously copied Michelangelo’s figures and made claims about their own pictorial mastery. Within the context of concerns about sacred images articulated in the Diálogos em Roma (1548) of Francisco de Holanda (1517–84), Clovio’s and Sebastiano’s painting techniques are discussed for their ability to approximate divine and semi-divine archetypes while signaling ontological difference and the authority of Rome. The metaphoric potential of Clovio’s and Sebastiano’s technical innovations, one invoking a Lucretian veil of atoms according to Holanda and the other a pictorial touchstone, also reveal the extent to which these artists ambitiously tied theory to practice.

De pestilitate is an interesting treatise on plague falsely attributed to Paracelsus and published as such by Johann Huser (who believed it authentic) in Paracelsus’s Bücher und Schrifften (1589–1591). It can be dated from before 1578. This article shows that it features conflicting cosmologies issued in different works of Paracelsus. This article also discusses its theory of plague, based on the correspondence between microcosm and macrocosm, as compared with the authentic plague theory of Paracelsus.

Full textAbstract:
Thesis (MPhil (Information Science))--Stellenbosch University, 2008.The functions of management and leadership are not new to the business fraternity. Whilst these functions are as pervasive and ubiquitous as the corporate organizations themselves, the same cannot be said of the organizational successes emanating from these functions. These functions have been cited throughout literature as pivotal in the successful running of businesses. By the same token, they have also been cited as the major causes of failed businesses within the corporate landscape. This has been established throughout small and big organizations alike. This unfortunate phenomenon has continued to attract significant academic and business research over the years with an overall intent of establishing why it is the case. Whilst there are varied reasons for the successes and failures of most organizations, the quality of both functions of leadership and management seem to take the larger portion of the praise and/or blame. These functions are regarded as key determinants of organizational success and survival into the future. Subsequently, this has culminated in myriad theories, frameworks and approaches around management and leadership as significantly different functions which yield different results in business organizations. At the core of the debate has been that management and leadership functions are different and depending on whether an organization is managed or led determines its future success and overall sustainability. It is therefore the intention of this study to comparatively analyze both functions of management and leadership in as far as they impact organizational sustainability and success. A case study of Jwaneng Diamond Mine in Botswana is used to do this comparative study of the two functions of management and leadership within the Executive team to try and affirm some of the key factors as alluded to within the business landscape. In this comparative study it is noted that whilst management and leadership are two different functions, they are however symbiotic in nature and successful organizations tap into both functions as they develop and build sustainable businesses for the future. The Jwaneng Mine case study showed that in an executive team, it is vital to have a balance between managers (those who provide management capabilities) and leaders (those that provide leadership) if the organization is to be successful going into the future.

Full textAbstract:
Background: Today, an increased need to value patents is expressed in several different situations. For example, banks more frequently accept patents as collateral for loans and patents are being exchanged more often between companies. It is argued that a hindrance for the recognition of the value of patents, and other assets lacking physical form, is that the current methods of valuation are not developed for this type of assets.
Purpose: Our objective is to investigate the practical relevance of four theoretical valuation approaches in the context of patent valuation and to point out crucial factors affecting the choice of valuation approach.
Procedure: Interviews were conducted with professionals working in the field of corporate finance and with an expert in the field of patents and intellectual property rights.
Results: The respondents are not of the same opinion whether relevant approaches for patent valuation exist at all. Among the respondents who find it possible to value patents, the income approach is the dominating approach. The theoretical correctness of this approach, derived from the definition of value, is stressed as the primary argument for the use of it. Methods such as Decision Tree Analysis, within the income approach, and Relief from Royalty, a hybrid of the market- and income approach, are used as complements.

Previous issue date: 2014-06-26The main goal of this paper is to analyze the Corporate Governance practices on the market value ratios of non-financial companies in the Construction industry, which are listed in the stock market of São Paulo BM&F BOVESPA, within the period of 2010 and 2013. It verifies whether or not companies that adopted differentiated level of Corporate Governance of Bovespa standards have reached higher levels of value creation to the shareholder, in other words, if the shareholders are willing to pay more for the shares of these companies based on the outcomes reached and consequently expected in the future. According to Silveira (2002: 02) the common sense indicates that companies with adequate structure of Corporate Governance practices recommended by Market agents have obtained better results and evaluation in the market for their share prices than companies with inadequate Corporate Governance structure, ceteris paribus . To Ross (2002: 46) adding to financial indexes: the financial statements are not capable to bring an answer to ( ) performance areas ( ). However, the business administration must continuing assesses the company s performance and the financial statements provide useful information . The financial statements and indexes were removed from the already calculated Economatica system, with exception of Tobin s Q Index, which was calculated by the author. It uses the statistic method of logic regression to verify if the variables (value creation indexes) can distinguish the companies listed in the special layer of Corporate Governance New Market. Hence, if the companies are listed in the special layer of Corporate Governance New Market, can add more value to the shareholders. As a result we can distinguish the companies in the New Market by significant variables P/E, P/B, P/Sales and P/EBITDA. Where the lower the P/E and P/B are, the higher is the chance for a company to meet the New Market level of 95% of trustworthiness rate, additionally the higher the P/Sales and P/EBITDA are, higher is the chance of a company in real estate industry been in the New Market layer of 95% of trustworthiness rate. It is concluded from this study that, for the companies that joined the differentiated levels of corporate governance practices and therefore are classified in the New Market, there was a higher value creation as it relates to the share price with EBITDA and the share price with sales. So there is evidence that investors focused their attention to value creation in operational indicators such as EBITDA and Sales
O objetivo principal deste trabalho é avaliar o reflexo das práticas de Governança Corporativa sobre os indicadores de valor de mercado das empresas não financeiras do setor de Construção com ações negociadas na Bolsa de Valores de São Paulo BM&F BOVESPA, no período de 2010 à 2013. Verifica-se se as empresas que aderiram aos níveis diferenciados de governança corporativa da Bovespa atingiram maiores níveis de criação de valor para o acionista, ou seja, se os investidores estão dispostos a pagar mais pelas ações destas empresas em função de resultados atingidos e consequentemente esperados para o futuro. Segundo Silveira (2002: 02) o senso comum indica que empresas com uma estrutura de governança corporativa mais adequada às práticas recomendadas pelos agentes de mercado obtenham melhores resultados e também sejam melhor avaliadas pelo mercado no preço de suas ações do que empresas com uma estrutura de governança não tão adequada, ceteris paribus . Já para Ross (2002: 46) complementa sobre índices financeiros: as demonstrações financeiras não são capazes de dar respostas para (...) áreas de desempenho (...). Entretanto, a administração precisa avaliar continuamente o desempenho da empresa, e as demonstrações financeiras fornecem informações úteis . As demonstrações financeiras e os índices foram retirados do sistema economática já calculados, com exceção do índice Q de Tobin que foi calculado pelo autor. Utiliza-se o método estatístico da regressão logística para verificar se as variáveis (índices de criação de valor) podem discriminar as empresas listadas no segmento especial de governança corporativa Novo Mercado. Ou seja, se as empresas listadas no segmento especial de governança corporativa Novo Mercado, podem agregar maior valor para seus acionistas. Como resultado temos que pode-se discriminar as empresas que estão no Novo Mercado pelas variáveis significativas P/L, P/VP, P/Vendas e P/EBITDA. Onde quanto menor o P/L e o P/VP, maior é a chance de uma empresa se encontrar no novo Mercado ao nível de 95% de confiança e quanto maior o P/Vendas e o P/EBITDA maior é a chance de uma empresa do setor imobiliário estar no novo Mercado com 95% de confiança. Conclui-se neste estudo que, para as empresas que aderiram a níveis diferenciados de práticas de governança corporativa e que por isso estão classificadas no Novo Mercado, houve maior criação de valor quando se relaciona o preço da ação com EBITDA e o preço da ação com as vendas. Portanto existem evidências de que os investidores concentraram sua atenção para criação de valor em indicadores operacionais como EBITDA e Vendas

Snyder, J. Lauren. "A critical theory of peace practice : discourse ethics and facilitated conflict resolution." Thesis, London School of Economics and Political Science (University of London), 2000. http://etheses.lse.ac.uk/1575/.
Full textAbstract:
This thesis argues for the need to answer the question how can we use critical theory to rethink the meta-theoretical foundations of facilitated conflict resolution. It draws on Jurgen Habermas' discourse ethics-based framework and a methodology of communicative rationality to articulate the foundations of a Critical Theory of Peace Practice. An illustrative example of the Oslo Channel, which led to the Declaration of Principles and Letters of Mutual Recognition between Israel and the PLO with the third- party facilitative assistance of Norwegians in 1993, sets the stage for exploring the extent to which facilitated conflict resolution approaches can contribute to peace practices. John Burton's ideas are critically and carefully examined as he has most extensively articulated the philosophical and theoretical underpinnings of such an approach. It is contended that although he identifies practices that differ from traditional mediation approaches, theoretically he remains committed to a behavioural-oriented human needs theory and is reliant on instrumental rationality in which success in the problem-solving setting is prioritised. Other scholars and practitioners who have attempted to expand and refine the Burtonian perspective are studied. It is argued that although each offers modifications to either the theory or the practice, all fail to fundamentally move beyond instrumental rationality and human needs theory. A communicative rationality methodology and a meta-theoretical foundation of Habermas' discourse ethics is proposed for grounding a theory of peace practice. By shifting the emphasis from needs to communication, this suggested framework is intended not only to impact the facilitation process, but the broader public sphere in which the legitimacy of any reached agreements must be accepted for establishing and sustaining peace. The most promising intimations of the praxeological dimensions of such an approach can be found in the realm of conflict transformation and peace-building with their associated desire to effect changes in socio-political arrangements.

Full textAbstract:
This thesis provides a critique of existing understandings of the Cold War in International Relations theory, and offers an alternative position. It rejects the conventional conceptual and temporal understanding of the Cold War, which assumes that the Cold War was, essentially, a political-military conflict between the United States and the Soviet Union that originated in the collapse of the wartime alliance after 1945. Using a method derived from historical materialism, in particular the parcellization of political power into the spheres of 'politics' and 'economics' that characterises capitalist modernity, the thesis develops an alternative understanding of the Cold War through an emphasis on the historical and thus conceptual uniqueness of it. After the literature survey, Part One interrogates the conceptual areas of the state, military power and social revolution and offers alternative conceptualisations. This is followed in Part Two with a more historically orientated argument that analyses Soviet and American responses to the Cuban and Vietnamese revolutions. The main conclusions of the thesis consist of the following. First, the thesis suggests that the form of politics in the USSR (and other 'revolutionary' states) was qualitatively different to that of capitalist states. This derived from the relationship between the form of political rule and the social relations of material production. Secondly, this conflict was not reducible to the 'superpowers' but rather, was conditioned by a dynamic associated with the expansion and penetration of capitalist social relations, and the contestation of those political forms that evolved from them. Finally, the relationship between capitalist expansion and the 'superpowers' rested on the distinctive forms of international relations of each superpower over how each related to the international system and responded to revolution.

Lee, Cheongho. "CREATIVITY, POSSIBILITY AND INTERPRETATION: THEORY OF DETERMINATION OF PEIRCE AND NEVILLE." OpenSIUC, 2018. https://opensiuc.lib.siu.edu/dissertations/1576.
Full textAbstract:
The central argument of this project is that meaningful and intelligible experience is conditioned by the determinate relationship between realms of reality, and that our humanity is grounded on the semiotic process of symbolic references, which is manifest in Charles S. Peirce’s and Robert C. Neville’s theories of determination. However they are contained by the past such processes of determination can be extended to the future through transformative effort. My investigation ranges over multiple paths that lead toward determinate processes, by suggesting that the problem of interpretation and of the intelligibility of experience can be solved only in reference to the full purview of determinate features of experience. In his theory of determination, Peirce considered two processes of determination, the semiotic process and epistemology. The semiotic process is an extensional process from object to interpretant that consists of an infinite chain of references that can be spatially reversible. The epistemological process of determination is temporal and irreversible, where the idea grows into the individual mind, as the universe is unfolded by the agency of mind. Peirce’s study of the logic of individuals of Duns Scotus is to find answers for the problem of individuality. For Peirce, God is individualized in the course of determination and at the same time determines all possible determinations. Due to his adopting the Scotian sense of necessity, Neville also adopts Duns Scotus’s logic of individuals to his theory of determination and valuation. As revealed in his theory of determination, in the ontological act of creation God becomes individual as a creator, an individual as the determiner of all possible determinations. In his theory of determination, Neville proposes modes of determination at the ontological level, as well as a collection of cosmological determinations. Neville works “inter-cosmologically” in order to account for the fundamental conditions of our knowing that brings ontological and cosmological determinations together. In their theory of interpretation, Peirce and Neville suggest a triadic system of semiotic network. Among other things, Neville provides a more sophisticated version of theory of interpretation, which involves realms of intelligibility. Both Peirce and Neville symbolism allows for the pragmatic semiotics based upon a brokenness of signs, which opens for further interpretation.

Harris, Kira Jade. "Leaving ideological social groups behind: A Grounded theory of psychological disengagement." Thesis, Edith Cowan University, Research Online, Perth, Western Australia, 2015. https://ro.ecu.edu.au/theses/1587.
Full textAbstract:
Much of the current disengagement literature focuses on the causes of an individual leaving a radical social group with the intention of countering fundamentalism and violent extremism. However, the link between the cause and the decision to disengage is unclear as one cause may facilitate disengagement for one member and not another. Minimal empirical research exists on the individual’s psychological experience of disengagement and the studies that have been done tend to focus on sole ideologies or group types. What is lacking in the field of disengagement is a broader understanding of the core psychological experience across a broad range of ideological social group types. The current research addressed this gap by including participants from a diverse range of ideological social groups, where the criterion that defined these social groups was the member’s identification. The strength of identification to the group was to be sufficiently strong so that members were willing to jeopardise their wellbeing, or that of others, for the benefit of the group’s objectives.
The current research sought to further the understanding of psychological disengagement and to construct a theory drawn from the experiences of those who have left ideological social groups. In-depth interviews were conducted with 27 former members of social groups with high levels of entitativity, such as one percent motorcycle clubs, military special operations forces, cults, white supremacy, and fundamental religious or political groups. Utilising a grounded theory methodology and analysis, the discrepancy between group membership and the self-concept was identified as the core theme in the disengagement experience. The grounded theory of psychological disengagement details the process of experiencing a threat relating to the self, identifying a self-concept discrepancy and subsequent methods to reduce this discrepancy, achieving physical disengagement and developing a post-exit identity.
The findings demonstrate that participants followed a consistent pattern of moving towards membership reappraisal and disengagement. This process began with a personal threat that was related to, or derived from, the social group, and ended with the reformation of the self as a former member. The group was perceived as inconsistent with the self-concept held by the participant in four domains; (1) competence, (2) virtue, (3) power and (4) significance. The inconsistency and the psychological identification with such a group conflicted with personally held goals and values, and threatened the participants’ psychological integrity. For the participants in the current study, this self-discrepancy was resolved by employing four self-concept management strategies to restore psychological integrity; (1) the forming of an atypical identity, (2) utilising adaptive preferences (3) using justifications and rationalisations, and (4) the making of amends. These self-concept strategies, applied in isolation or in combination, contributed to participants psychologically, as well as physically, disengaging from the group as a means of restoring consistency between their self-concept and social identity. The physical disengagement led to initial feelings of relief over the decision-making process and freedom over the removal of lifestyle restrictions. These positive emotions gave way to feelings of grief over the loss of positive in-group aspects and concerns for the future. A post exit identity was adopted when the group experience was embraced and personal reflections followed a more positive approach.
Implications for policy and specific areas where members may benefit from additional support are identified. This research contributes to the current understanding of disengagement, as well as group dependency and ideological attachment from a unique perspective. Directions for future research and implementations of the findings of the current research are discussed.

Pianov, Dmitrii. "Allocation Mechanisms in Partially Linked Secondary Spectrum Markets: A Theory And Experiment." OpenSIUC, 2018. https://opensiuc.lib.siu.edu/dissertations/1518.
Full textAbstract:
We analyze dynamic equilibria of a multiple markets model with sparsely allocated participants. An example of such a market is the secondary radio spectrum market. In the first chapter a general model is represented by an allocation of a good from sellers to buyers where purchases can only occur if a buyer and seller are linked or if a buyer is located in the seller's coverage area. First, we study the static part of the model and show an optimal auction design for price efficiency. Second, we assume a dynamic structure where buyers can reallocate and show sufficient conditions to reach equilibrium. Finally, we consider the speed of convergence to an equilibrium and prove the equilibrium is allocation efficient. The second chapter expands the idea of a location based market. We consider a mechanism of allocating a differentiated good. To capture this, we use the idea of a Generalized Second Price Auction that is used extensively in online search auctions. Buyers in this market are competing for various goods that are ranked based on their quality (known as the click-through rate in online advertisement). Network formation is also assumed to capture different accessibility of participants to the market. In terms of secondary spectrum auctions, this mechanism can be thought of as competition of various wireless devices (such as cognitive radio) over broadcast priority from the base station. We provide the conditions and subset of networks that will lead to an equilibrium in this market. We also show how different constraints, such as transaction costs and interference, have an impact on this equilibrium. In the third chapter, we study two mechanisms of secondary allocation for trading spectrum in a dynamic setting. The two models considered are the "exclusive-use" model, where spectrum is traded on the open market, and the "commons-use" model, where spectrum is available freely in a non-coordinated way. We show that firms have more incentive to innovate and to acquire higher capital in the "exclusive-use" case, which results in higher welfare. We test these results with both numerical simulations and with a laboratory experiment to simulate the conditions of such markets and show that the theoretical results hold true.

Full textAbstract:
Approximation algorithms employing Monte Carlo methods, across application domains, often require as a subroutine the estimation of the mean of a random variable with support on [0,1]. One wishes to estimate this mean to within a user-specified error, using as few samples from the simulated distribution as possible. In the case that the mean being estimated is small, one is then interested in controlling the relative error of the estimate. We introduce a new (epsilon, delta) relative error approximation scheme for [0,1] random variables and provide a comparison of this algorithm's performance to that of an existing approximation scheme, both establishing theoretical bounds on the expected number of samples required by the two algorithms and empirically comparing the samples used when the algorithms are employed for a particular application.

Full textAbstract:
In the Slavic grammar books of the 16th-17th centuries, the category of dual was represented in the fi rst Slovenian grammar book «Arcticae horulae succisivae» (1584, Wit-tenberg) by the Protestant grammarian A. Bohorič (1520 –1588) and in the grammar book of the Church Slavonic lan-guage «Slavonic Grammar with Correct Syntax» (1619, Jevje) by M. Smotrytsky (1578–1633 (?)).It was assumed earlier that the Slovenian grammar had had a possible impact on Smotrytsky’s Grammar. However, the analysis of the dual forms in Bohorič’s G r a m m a r and Smotrytsky’s Grammar showed that such an impact was most likely impossible. When creating their gram-mar books, the authors were guided by different aims: if A. Bohorič was following the practice of using the forms of a living language, then Smotrytsky was orienting towards the fi xed stable forms of dead written language.

Abstract Polysilicon materials from three different suppliers were tested in tension to determine their Young’s modulus and strength. The modulus of polysilicon from Cronos was 158 ± 8 GPa and its strength 1.56 ± 0.25 GPa, and the material from Sandia National Laboratories showed 157 ± 6.5 GPa and 3.09 ± 0.18 GPa. Two polysilicons from Standard MEMS Inc. showed 164 ± 11.2 GPa and 152 ± 10.0 GPa for modulus values and 2.08 ± 0.35 GPa and 2.00 ± 0.25 GPa for strengths. Polysilicon is therefore similar to most structural materials in that its modulus is essentially constant, but its strength can depend on processing.

Full textAbstract:
"This case study is based on two accounting books that belonged to merchant Matteus Spielmann, which are preserved in the Tallinn City Archives and date from 1568-1570. Ever since Luca Pacioli’s famous 1494 textbook on accounting (the so-called Summa de arithmetica, geometry, proportioni et proportionalita), ethics has served as one of the foundations of accounting [1]. Business ethics and sustainability are related, in some ways characterizing corporate social responsibility. For example, Garriga and Melé claim that the theory of sustainable development belongs to the ethical theories of corporate social responsibility, concentrating on ethical values and responsibility [2]. The aim of this paper was to determine how Spielmann’s accounting books reflect ethics and sustainability. In order to assess sustainability, Talcott Parsons’s paradigm about the continuity of social systems was applied. According to Parsons [3], a harmony or balance must exist between the main functions of social systems: adaptation to the environment (A), goals attainment (G), social integration (I), and latent pattern maintenance or latency of values (L). In her doctoral thesis, Roostalu proved that Parsons’s AGIL paradigm describes a general system of sustainability and it is applicable when preparing four-dimensional sustainability models [4]. In this paper, a four-dimensional content model was also prepared, and qualitative content analysis was used. The results of the case study show that Spielmann’s accounting books are quite transparent and include several sustainability indicators. Moreover, it appears that the dimensions of the sustainability model are in harmony with each other, which indicates strong sustainability orientation in these accounting books dating from the Middle Ages."

Wellbeing in UK Frontline Healthcare Workers During Peaks One and Three of the COVID-19 Pandemic: A Retrospective Cross-Sectional Analysis. Science Repository, December 2022. http://dx.doi.org/10.31487/j.ejgm.2022.01.01.
Full textAbstract:
Background: COVID-19 had a huge impact on the wellbeing of healthcare workers (HCWs). This is well documented during the first peak of the pandemic. With cases in the UK rising for a third peak, hospitalisations and deaths surpassing the first, there is very little known about the mental health of HCWs during this time. Methods: Using a questionnaire, data was collected from patient-facing staff at Barking, Havering, and Redbridge University Trust to quantify and compare the period prevalence of symptoms of depression, anxiety, and PTSD during the first peak (P1: March-May 2020) and third peak (P3: December 2020-Feburary 2021) of the COVID-19 pandemic as well as wellbeing service use, demographics of responders and what they found most difficult during the peaks. Results: Of 158 responders, only 22·4% felt they had enough access to wellbeing services during P1 and 21·5% in P3. Of those who used wellbeing services 34·4% found them useful in P1 and 34·6% in P3. 70·3% of responders felt that not enough was done for staff wellbeing. The median anxiety score decreased from P1 (10(range 5-17)) to P3 (8(range 4-16)) p=0·031. Under 30-year-olds’ depression and PTSD scores increased from P1 to P3 (depression: P1 7(1-11), P3 8(3-14), p=0·048, PTSD: P1 4(0-7) peak 3 5(2-9), p=0·037). Several groups showed a decrease in anxiety scores from P1 to P3 including; over 30-year-olds (P1 10(5-17), P3 7(3-15) p=0·002), BME responders (P1 8(3·75-15) P3 6·5(1-12) p=0·006), AHP (P1 14(7-19), P3 11(5-19) p=0·005), ITU workers (P1 15(8-18·25) P3 12(5·75-18·25) p=0·004), and those who were redeployed (P1 8(5-18·25), P3 5(2-14·75), p=0·032). Conclusion: We have observed changes in mental health symptoms within the study population as the peaks of the pandemic continue. With the majority of responders reporting they felt not enough had been done for their wellbeing support - and of those who used the wellbeing services only around 1/3 felt they were useful - we hope that this paper can help inform wellbeing provision and identify groups at higher risk of developing mental health symptoms.

Full textAbstract:
This annual report marks the fifteenth year anniversary of Ocean Exploration Trust’s (OET) E/V Nautilus exploring poorly known parts of our global ocean in search of new discoveries. Since its first season in 2009, E/V Nautilus has conducted a total of 158 expeditions that explored our ocean throughout the Black Sea, Mediterranean, Atlantic, Caribbean, and Pacific for a total of 1,970 days at sea (~5.5 years). These scientific expeditions included a total of 1,017 successful ROV dives, as well as mapped over 1,053,000 km2 of seafloor. The results of these exploratory expeditions have been summarized in over 300 peer-reviewed scientific publications covering a wide range of scientific disciplines, including marine geology, biology, archaeology, chemistry, technology development, and the social sciences. Throughout its 15-year history, E/V Nautilus has been not only a platform for ocean exploration and discovery, but also an inclusive workspace that has provided pathways for more people, especially those early in their careers, to experience and enter ocean exploration professions. It has also catalyzed numerous technological innovations, multi-disciplinary collaborations, and inspired millions through OET’s extensive outreach initiatives. The 2023 field season was no exception, with E/V Nautilus undertaking 12 multi-disciplinary expeditions that explored some of the most remote and poorly surveyed areas in the Pacific, all of which included numerous activities to share expedition stories with diverse audiences across the globe.

Full textAbstract:
The article is devoted to the analysis of the digital content of publications of one issue of the daily All-Ukrainian newspaper “Den” (March 13-14, 2020). The author aims to identify the main thematic groups of digital designations, as well as to consider cases of justified and unsuccessful use of digital designations. Applying the content analysis method, the author identifies publications that contain numerical notations, determines the number of such notations and their affiliation with the main subject groups. Finds that the thematic group of digital designations “time” (58.6% of all digital designations) is much more dominant. This indicates that timing is the most important task of a newspaper text. The second largest group of digital designations is “measure” (15.8% of all digital designations). It covers dimensions and proportions, measurements of distance, weight, volume, and more. The third largest group of digital signage is money (8.2% of all digital signage), the fourth is numbering (5.2% of all digital signage), and the fifth is people (4.4% of all digital signage). The author focuses on the fact that the digits of the journalist’s text are both a source of information and a catch for the reader. Vivid indicators give the text a sense of accuracy. When referring digital data to the text, journalists must adhere to certain rules for the writing of ordinal numbers with incremental graduation; submission of dates; pointing to unique integers that are combined (or not combined) with units of physical quantities, monetary units, etc.; writing a numerator at the beginning of a sentence; unified presentation of data. This will greatly facilitate the reader’s perception of the information.

Full textAbstract:
The Southeast Coast Network (SECN) conducts long-term terrestrial vegetation monitoring as part of the nationwide Inventory and Monitoring Program of the National Park Service (NPS). The vegetation community vital sign is one of the primary-tier resources identified by SECN park managers, and it is currently conducted on 15 network parks (DeVivo et al. 2008). Monitoring plants and their associated communities over time allows for targeted understanding of ecosystems within the SECN geography, which provides managers information about the degree of change within their parks’ natural vegetation. 2019 marks the first year of conducting this monitoring effort on four SECN parks, including Timucuan Ecological and Historic Preserve (TIMU). A total of 23 vegetation plots were established in the park in May and June. Data collected in each plot include species richness across multiple spatial scales, species-specific cover and constancy, species-specific woody stem seedling/sapling counts and adult tree (greater than 10 centimeters [3.9 inches (in)]) diameter at breast height (DBH), overall tree health, landform, soil, observed disturbance, and woody biomass (i.e., fuel load) estimates. This report summarizes the baseline (year 1) terrestrial vegetation data collected at Timucuan Ecological and Historic Preserve in 2019. Data were stratified across three dominant broadly defined habitats within the park (Coastal Plain Nonalluvial Wetlands, Coastal Plain Open Uplands and Woodlands, and Maritime Upland Forests and Shrublands) and three land parcels (Cedar Point, Theodore Roosevelt, and Thomas Creek). Noteworthy findings include: A total of 157 vascular plant taxa (species or lower) were observed across 23 vegetation plots, including nine species not previously known from the park. Three plots were located in the footprint of the Yellow Bluff Fire, and were sampled only two weeks following the fire event. Muscadine (Muscadinia rotundifolia), cat greenbrier (Smilax glauca), water oak (Quercus nigra), and swamp tupelo (Nyssa biflora) were the most frequently encountered species in Coastal Plain Nonalluvial Wetland habitat; saw palmetto (Serenoa repens), slash pine (Pinus elliottii), and gallberry (Ilex glabra) were the most frequently encountered species in Coastal Plain Open Upland and Woodland habitat; and Darlington oak (Quercus hemisphaerica), Spanish moss (Tillandsia usenoides), and red bay (Persea borbonia) were the most frequently encountered species in Maritime Upland Forests and Shrublands. There were no exotic species of the Florida Exotic Pest Plant Council list of invasive plants (FLEPPC 2020) observed on any of these plots. Both red bay and swamp bay (Persea palustris) were largely absent from the tree stratum in these plots; however, they were present (occasionally in high abundance) in the seedling and sapling strata across all habitat types. Buckthorn bully (Sideroxylon lycioides)—listed as Endangered in the state of Florida by the Florida Department of Agriculture and Consumer Services (FDACS 2020)—was observed in three Maritime Upland Forest and Shrubland plots. The tree strata in each broadly defined habitat were dominated by the following species: Coastal Plain Nonalluvial Wetlands-loblolly bay (Gordonia lasianthus) Coastal Plain Open Uplands and Woodlands-longleaf pine (Pinus palustris) Maritime Upland Forests and Shrublands-oaks (Quercus sp.) Most stems within the tree strata exhibited healthy vigor and only moderate dieback across all habitat types. However, there was a large amount of standing dead trees in plots within Maritime Upland Forests and Shrublands. Downed woody biomass (fuel loads) were highest in the Cedar Point and Thomas Creek land parcels.

Full textAbstract:
The antibotulinal baceriocins, propionicin PLG-1 and jenseniin G., were the first to be identified, purified and characterized for the dairy propionibaceria and are produced by Propionibacterium thoenii P127 and P. thoenii/jensenii P126, respectively. Objectives of this project were to (a) produce polyclonal antibodies for detection, comparison and monitoring of propionicin PLG-1; (b) identify, clone and characterize the propionicin PLG-1 (plg-1) and jenseniin G (jnG) genes; and (3) develop gene transfer systems for dairy propionibacteria using them as models. Polyclonal antibodies for detection, comparison and monitoring of propionicin PLG-1 were produced in rabbits. Anti-PLG-1 antiserum had high titers (256,000 to 512,000), neutralized PLG-1 activity, and detected purified PLG-1 at 0.10 mg/ml (indirect ELISA) and 0.033 mg/ml (competitive indirect ELISA). Thirty-nine of 158 strains (most P. thoenii or P. jensenii) yielded cross-reacting material; four strains of P. thoenii, including two previously unidentified bacteriocin producers, showed biological activity. Eight propionicin-negative P127 mutants produced neither ELISA response nor biological activity. Western blot analyses of supernates detected a PLG-1 band at 9.1 kDa and two additional protein bands with apparent molecular weights of 16.2 and 27.5 kDa. PLG-1 polyclonal antibodies were used for detection of jenseniin G. PLG-1 antibodies neutralized jenseniin G activity and detected a jenseniin G-sized, 3.5 kDa peptide. Preliminary immunoprecipitation of crude preparations with PLG-1 antibodies yielded three proteins including an active 3-4 kDa band. Propionicin PLG-1 antibodies were used to screen a P. jensenii/thoenii P126 genomic expression library. Complete sequencing of a cloned insert identified by PLG-1 antibodies revealed a putative response regulator, transport protein, transmembrane protein and an open reading frame (ORF) potentially encoding jenseniin G. PCR cloning of the putative plg-1 gene yielded a 1,100 bp fragment with a 355 bp ORF encoding 118 amino acids; the deduced N-terminus was similar to the known PLG-1 N-terminus. The 118 amino acid sequence deduced from the putative plg-1 gene was larger than PLG-1 possibly due to post-translational processing. The product of the putative plg-1 gene had a calculated molecular weight of 12.8 kDa, a pI of 11.7, 14 negatively charged residues (Asp+Glu) and 24 positively charged residues (Arg+Lys). The putative plg-1 gene was expressed as an inducible fusion protein with a six-histidine residue tag. Metal affinity chromatography of the fused protein yielded a homogeneous product. The fused purified protein sequence matched the deduced putative plg-1 gene sequence. The data preliminarily suggest that both the plg-1 and jnG genes have been identified and cloned. Demonstrating that antibodies can be produced for propionicin PLG-1 and that those antibodies can be used to detect, monitor and compare activity throughout growth and purification was an important step towards monitoring PLG-1 concentrations in food systems. The unexpected but fortunate cross-reactivity of PLG-1 antibodies with jenseniin G led to selective recovery of jenseniin G by immunoprecipitation. Further refinement of this separation technique could lead to powerful affinity methods for rapid, specific separation of the two bacteriocins and thus facilitate their availability for industrial or pharmaceutical uses. Preliminary identification of genes encoding the two dairy propionibacteria bacteriocins must be confirmed; further analysis will provide means for understanding how they work, for increasing their production and for manipulating the peptides to increase their target species. Further development of these systems would contribute to basic knowledge about dairy propionibacteria and has potential for improving other industrially significant characteristics.

Full textAbstract:
The Jockey Hollow section and the New Jersey Brigade Area of Morristown National Historical Park (MORR) are predominantly comprised of upland oak-hickory forests that have regrown over the past 200 years from previous land uses. The forest is being damaged by two major stressors, a large population of white-tailed deer and an abundance of non-native, invasive shrubs and herbaceous species. This study explores changes to the forest over 26 years and suggests management techniques to avoid future degradation. The forest is typical of many upland stands in the region, and studies here would be applicable to many lands controlled by the National Park Service and to many public and private land owners. In 1995, 18 vegetation experimental plots were established in the forest, each 20 x 20 m. Ten plots were in areas that had no non-native, invasive plants. The other eight plots had invasive species. All trees, shrubs and a sampling of herbs were recorded in each of the 18 plots. At that time, no GPS technology was available and handwritten maps were used to record locations. The plots were revisited and resurveyed in 2001; however, only 13 plots were found. This 2021 study is a new survey of the plot conditions. The investigators were able to relocate 17 of the original plots. New GPS locations were recorded for these 17 plots to facilitate future studies. The goal of the study was to test if changes over 26 years in forest conditions differed between the original invaded plots as compared to the uninvaded plots. Also, these data will allow us to measure the progress of invasion into previously uninvaded areas. Together, these results will allow the forest managers to focus attention on the most aggressive plant invaders and to understand the fate of this forest type that is being challenged by deer and non-native plants. Over the last 26 years there has been no hunting for deer here. Also, the plots were not within the few deer exclosures at MORR; deer were able to enter the landscape from surrounding heavily wooded areas. Data were collected in four layers of vegetation – mature trees, saplings, shrubs, and herbaceous groundcovers. The mature trees in the invaded forest plots demonstrated declining trends. The species richness declined by 6%, the average number of trees declined by 30%, white ash and flowering dogwood had the most losses, and basal area did not increase over time because very few new saplings grew into mature tree sizes. The uninvaded plots’ mature trees also revealed a 20% declined in richness, number of trees declined by 18%, the greatest losses occurred for red maple and black birch, but basal area increased slightly due to growth of large persisting trees. Saplings in the invaded forest experienced declines over the 26 years. Species richness declined by 38%, number of native saplings decreased by 44%, and number of invasive saplings increased by 600%. In the uninvaded forest, the conditions and trends were variable. Richness decreased by 21%, no invasive saplings found, number of native saplings increased by 37% (due to increases in American beech). With American beech excluded, the number of native saplings decreased by 60%. In both forest types, the declining number of native saplings was primarily caused by excessive deer damage. For the shrub layer in invaded plots, Japanese barberry stems increased by 122% by 2001 and 276% by 2021. Barberry became the dominant species. Similarly, wineberry stands increased 486% in 2001 and 157% for 2021. It is now the second most common species. However, in the uninvaded plots there was no significant increase in the number of barberry stems and wineberry was not present in 1995 or 2001, and only averaged 1.5 stems per plot in 2021. Neither species has a significant presence now and eradication is possible. A major finding is that the process of invasion of these shrubs over 26 years is very slow. For the herbaceous plants, in the invaded plots there was a sharp decrease in cover by 2021 due to the competitive impact by the abundant invasive shrubs. The invasive Japanese stiltgrass declined 86% in cover and native Carex (sedge) species declined by 78%. In the uninvaded forest plots, stiltgrass was present in very low amounts and did not increase significantly over 26 years. The number of quadrats with any stiltgrass only increased from 3 to 5 over the 26 years. These data show that stiltgrass invades slowly in the uninvaded plots, but in the invaded plots it was greatly replaced by invasive shrubs. Overall, the rate of change of the native herb cover was slow. Together, these data suggest that currently uninvaded forest areas can be protected by monitoring and rigorously eliminating any initial invasions by non-native shrubs and herbs. Once these species reach a significant presence in number of stems or cover in a plot they explode in number. Early intervention when invasive plants first appear is the most practical management tool. Reduction of deer density will also increase the reproductive potential and sustainability of our main forest tree species. Planting of new young canopy tree species, with protection from deer, can retard the ability of invasive plants to begin new populations.

Full textAbstract:
Theodore Roosevelt National Park (THRO) in western North Dakota was established for its historical connections with President Theodore Roosevelt. It contains not only historical and cultural resources, but abundant natural resources as well. Among these is one of the best geological and paleontological records of the Paleocene Epoch (66 to 56 million years ago) of any park in the National Park System. The Paleocene Epoch is of great scientific interest due to the great mass extinction that occurred at its opening (the Cretaceous–Paleogene extinction event), and the unusual climatic event that began at the end of the epoch (the Paleocene–Eocene Thermal Maximum, an anomalous global temperature spike). It is during the Paleocene that mammals began to diversify and move into the large-bodied niches vacated by dinosaurs. The rocks exposed at THRO preserve the latter part of the Paleocene, when mammals were proliferating and crocodiles were the largest predators. Western North Dakota was warmer and wetter with swampy forests; today these are preserved as the “petrified forests” that are one of THRO’s notable features. Despite abundant fossil resources, THRO has not historically been a scene of significant paleontological exploration. For example, the fossil forests have only had one published scientific description, and that report focused on the associated paleosols (“fossil soils”). The widespread petrified wood of the area has been known since at least the 19th century and was considered significant enough to be a tourist draw in the decades leading up to the establishment of THRO in 1947. Paleontologists occasionally collected and described fossil specimens from the park over the next few decades, but the true extent of paleontological resources was not realized until a joint North Dakota Geological Survey–NPS investigation under John Hoganson and Johnathan Campbell between 1994–1996. This survey uncovered 400 paleontological localities within the park representing a variety of plant, invertebrate, vertebrate, and trace fossils. Limited investigation and occasional collection of noteworthy specimens took place over the next two decades. In 2020, a new two-year initiative to further document the park’s paleontological resources began. This inventory, which was the basis for this report, identified another 158 fossil localities, some yielding taxa not recorded by the previous survey. Additional specimens were collected from the surface, among them a partial skeleton of a choristodere (an extinct aquatic reptile), dental material of two mammal taxa not previously recorded at THRO, and the first bird track found at the park. The inventory also provided an assessment of an area scheduled for ground-disturbing maintenance. This inventory is intended to inform future paleontological resource research, management, protection, and interpretation at THRO. THRO’s bedrock geology is dominated by two Paleocene rock formations: the Bullion Creek Formation and the overlying Sentinel Butte Formation of the Fort Union Group. Weathering of these formations has produced the distinctive banded badlands seen in THRO today. These two formations were deposited under very different conditions than the current conditions of western North Dakota. In the Paleocene, the region was warm and wet, with a landscape dominated by swamps, lakes, and rivers. Great forests now represented by petrified wood grew throughout the area. Freshwater mollusks, fish, amphibians (including giant salamanders), turtles, choristoderes, and crocodilians abounded in the ancient wetlands, while a variety of mammals representing either extinct lineages or the early forebearers of modern groups inhabited the land. There is little representation of the next 56 million years at THRO. The only evidence we have of events in the park for most of these millions of years is isolated Neogene lag deposits and terrace gravel. Quaternary surficial deposits have yielded a few fossils...

Ward, Kimiora. Sierra Nevada Network high elevation white pine monitoring: 2021 annual report. National Park Service, 2024. http://dx.doi.org/10.36967/2302327.
Full textAbstract:
Five-needle white pines (Family Pinaceae, Genus Pinus, Subgenus Strobus), and in particular whitebark pine (Pinus albicaulis), limber pine (P. flexilis), and foxtail pine (P. balfouriana) are foundation species in upper subalpine and treeline forests of several National Park Service Pacific West Region parks, including Sequoia and Kings Canyon National Parks (SEKI) and Yosemite National Park (YOSE). The Sierra Nevada Network Inventory & Monitoring Program, in collaboration with the Klamath Network, Upper Columbia Basin Network, and Mojave Desert Network have implemented a joint long-term monitoring protocol to assess the current status and future trends in high elevation white pine communities. Key demographic parameters within white pine forest communities will be estimated by monitoring individual trees within permanent plots through time. This report documents the results of the 2021 field season, which was the eighth year of monitoring in Sequoia and Kings Canyon National Parks (SEKI) and Yosemite National Park (YOSE). The 2021 goal was to complete the third full re-measure of the second of three rotating panels (Panel 2) for each species-park population: YOSE-whitebark pine, SEKI-whitebark pine, and SEKI-foxtail pine. Each panel consists of 12 permanent 50 x 50 m (2,500 m2) plots that were randomly selected for each of the three populations. The full sampling array thus includes a total of 36 whitebark pine plots in YOSE, 36 whitebark pine plots in SEKI, and 36 foxtail pine plots in SEKI. Data from plot surveys will be used to characterize white pine forest community dynamics in SEKI and YOSE, including changes in tree species composition, forest structure, forest health, and demographics. The first full measure of all Panel 2 plots was completed over two years in 2013-2014, then a full remeasure of both parks? whitebark pine Panel 2 was conducted in 2016, with 10 of 12 SEKI-foxtail plots sampled that year. A third remeasure of all Panel 2 plots was not possible in 2021 because a smaller crew size was necessary during the COVID-19 pandemic. In total, the crew visited 37 sites, and sampled 31, during the 2021 field season. One plot in the YOSE whitebark pine frame was uninstalled before reading and one plot in the SEKI whitebark pine frame was uninstalled after reading, both for safety concerns. Four plots were not visited due to lack of capacity with the reduced crew size: one in each of the YOSE and SEKI whitebark frames, and three in the SEKI foxtail frame. A plot from Panel 3 in each of the parks? whitebark frames was measured, for a total of 11 plots measured in each whitebark pine frame. Nine plots were measured in the SEKI foxtail pine frame. Within the 31 plots completed, a total of 5,728 trees was measured. Species composition, forest structure, and factors affecting tree health and reproduction, including incidence and severity of white pine blister rust (Cronartium ribicola) infection, mountain pine beetle (Dendroctonus ponderosae) infestation, dwarf mistletoe (Arceuthobium spp.) infection, canopy kill, female cone production and regeneration were recorded. During the 2021 field season, crews continued to count the total number of mature cones per tree for whitebark and foxtail pine, use crown condition codes to assess crown health, and tag individual seedlings to be tracked through time. All three of these procedures started in 2017 and are to be evaluated by each of the three participating networks over several years, to determine whether they should become permanent changes to the monitoring protocol. In YOSE, 11 whitebark pine plots were re-measured, from Panels 2 and 3. A total of 2,810 trees were sampled, which included 586 live whitebark pine trees and 2,097 other live conifers. An additional 127 trees (including 17 whitebark pine) were recorded as dead. The forest crew noted little sign of white pine blister rust (WPBR) in Yosemite in 2021, and just a single inactive canker was observed on one whitebark pine in Panel 3, Plot 42, near Dana Meadows. This infection was new to plot 42, and it expands the total number of plots where white pine blister rust has been documented in Yosemite to six. The crew also noted little mountain pine beetle activity, documenting beetle galleries on 15 lodgepole pines in three Panel 2 plots. Dwarf mistletoe was not observed. The average number of live whitebark pine trees per plot was 53 (SD = 56). This was a low cone crop year for whitebark pine, with two percent of live whitebark pine trees producing female cones. Cone bearing trees averaged 2 (SD = 1) cones per tree. Whitebark pine seedling density averaged 90 (SD = 157) seedlings per hectare. The largest number of whitebark pine seedlings found in a plot was four, and three of the eleven plots contained whitebark seedlings. In SEKI, 10 of 12 Panel 2, and one Panel 3, whitebark pine plots were re-measured. Within these plots, 1,246 live whitebark pine, 30 live foxtail pine, and 861 other live conifers were sampled. WPBR was infrequently documented in the SEKI whitebark frame as well, with indicators of infection in Plot 31 near Window Creek and Plot 44 near Upper State Lake. These were the first infections documented in these plots, bringing the number of plots where WPBR has been documented in the SEKI whitebark panel to nine. Although WPBR was documented in Plot 27 near Charlotte Dome in 2016, it was not documented this year because putative cankers showing three signs of infection in 2016 showed only two or fewer signs in 2021. Mountain pine beetle activity was observed in one live lodgepole pine and two recently dead whitebark pine, within three plots in the SEKI whitebark sample frame. An exception to the low levels of mountain pine beetle activity was outside Plot 31 in the Window Creek area, where the forest crew noted many recently dead whitebark pine with signs of beetle activity. Dwarf mistletoe was not encountered. The average number of live whitebark pine trees per plot was 113 (SD = 86). Less than one percent of live whitebark pine trees produced female cones, each producing on average 2 (SD = 1) cones. Whitebark seedling regeneration averaged 303 (SD = 319) seedlings per hectare. The largest number of whitebark seedlings found in a plot was eight, and eight of the 11 plots contained whitebark seedlings. Nine of the 12 SEKI foxtail Panel 3 plots were remeasured. Within these plots, 413 live foxtail pine, 67 live whitebark pine, and 402 other live conifers were sampled. Ninety-two dead or recently dead trees were also documented, 65 of which were foxtail pine. No signs of blister rust infection, mistletoe, or mountain pine beetle were observed in the foxtail plots sampled. The average number of foxtail pine trees per plot was 46 (SD = 33). Fifty-four percent of the foxtail pine trees produced female cones, averaging 14 (SD =15) cones/tree. Only one foxtail pine seedling was recorded within the 9 foxtail pine plots, resulting in an estimated 14 (SD = 41) seedlings per hectare. Eight whitebark pine seedlings were also found within two plots.

Full textAbstract:
MGR recorded 1570 violent incidents during January 2024, mostly triggered by politics, access to resources, and other socio-economic factors. More than 217 deaths and 1991 injuries have been recorded from these incidents. The highest number of violent incidents have been recorded in the form of clashes and attacks (670). Some 738 incidents are directly political violence, protests and arrests which resulted in 34 deaths. Geographically, Chittagong (395) scores the highest number of violence followed by Dhaka (310), Barishal (254), Khulna (178) and Rajshahi (170). There were 120 protests and demonstrations and atleast 83 of protests were triggered by politics. While some 24.91% of political violence contributed by Bangladesh Awami League & affiliates, 8.72% contributed by the Bangladesh Nationalist Party (BNP). Activists of independent election candidates conducted 16.01% of political violence. Intra-party violence within the Awami League showed a significant surge in January as Awami League to encourage 'independents' for 'participatory' polls. Whereas 63% incidents were rural, 37% violence incidents took place in urban areas. In this month, student violence increased with a total of 41 cases reported across different regions. In the election week (January 1-7), a total of 423 instances of electoral violence and irregularities occurred, leading to 599 non-lethal casualties, 7 fatalities, 177 arrests, and 232 cases of property destruction. On the day of the election, the country witnessed 90 incidents of electoral violence and 44 cases of electoral irregularities.
