Akimov, Yury G. "Coalition Avenir Québec’s Politics: Autonomism, Nationalism and Pragmatism." USA & Canada Economics – Politics – Culture, no. 9 (December 15, 2023): 87–99. http://dx.doi.org/10.31857/s2686673023090079.
Abstract:
The article deals with the mainstreams of Quebec politics under Coalition Avenir Québec (CAQ) government headed by François Legault (from 2018 to the present). It is noted that the CAQ represents a new political force in provincial politics, offering the québécois society a middle/intermediate path of development between the Liberals (federalists) and the Pequist (supporters of sovereignty). The distinctive features of this path are the desire to strengthen autonomy of Quebec in Canadian Federation, reliance on québécois nationalism, consistent and tough defense of the dominant position of the French language in the province, as well as protection and promotion of Quebec values. At the same time, Legault policy is characterized by pragmatism and a generally balanced approach to socio-economic and environmental issues. The article discusses the Act respecting the laicity of the State (Bill 21) and the Act Respecting French, the Official and Common Language of Quebec (Bill 96), adopted under the CAQ Government. It also highlights the effectiveness of the Legault government’s actions during the COVID-19 pandemic and compares the results of the 2018 and 2022 provincial elections.

Abstract:
Avenacinase activity has been shown to be a key factor determining the host range of Gaeumannomyces graminis on oats (Avena sativa). G. graminis var. avenae produces avenacinase, which detoxifies the oat root saponin avenacin, enabling it to infect oats. G. graminis var. tritici does not produce avenacinase and is unable to infect oats. G. graminis var. avenae is also reported to incite take-all patch on creeping bentgrass (Agrostis stolonifera). It is unknown whether creeping bentgrass produces avenacin and if the avenacin-avenacinase interaction influences G. graminis pathogenicity on creeping bentgrass. The root extracts of six creeping bentgrass cultivars were analyzed by fluorimetry, thin-layer chromatography, and high performance liquid chromatography for avenacin content. Avenacin was not detected in any creeping bentgrass cultivars, and pathogenicity assays confirmed that both G. graminis var. avenae and G. graminis var. tritici can infect creeping bentgrass and wheat (Triticum aestivum), but only G. graminis var. avenae incited disease on oats. These results are consistent with the root analyses and confirm that avenacinase activity is not required for creeping bentgrass infection by G. graminis.

Abstract:
Social media is changing the way individuals collaborate, learn and express themselves, allowing for the construction of an identity and a reputation that encompasses over many other digital spaces. In a context where the online identity of individuals may reveal the sum of their experiences and skills, reflecting the path of their personal, academic and professional lives, this paper introduces a conceptual framework and a model developed to analyse the construction of the self in online environments. The model was used in a research study developed at University of Aveiro, Portugal, aiming to analyse how identity is built and managed in formal and informal digital environments and reveals the existence of two main online identity profiles – context driven and user-driven identity profiles.

Abstract:
Due to their complex textual affiliations, great popularity, and historical significance, Guy of Warwick and its Anglo-Norman progenitor, Gui de Warewic, have been a favourite subject for textual criticism, thematic analysis, and cultural studies. Following in that vein, this paper will examine the cultural and textual contexts of several morally problematic episodes. Chief among them is a passage in which Guy kills the Earl Florentine’s son after the young man had attacked him for poaching, and then defeats the father in battle when the latter seeks to avenge his son’s death. This ‘Florentine episode’ can be tied to two other critical passages: one, prior to it, detailing how Guy’s ally, the Duke Segyn, is driven to kill his liege lord’s nephew, and another, later, in which Guy rejects secular chivalry for a divinely oriented path. Each passage, while present in some witnesses of the romance, is altered or absent in others.

Abstract:
Take-all patch, caused by Gaeumannomyces graminis (Sacc.) Arx. & D. Olivier var. avenae (E.M. Turner) Dennis (Gga), is a disease of creeping bentgrass (Agrostis stolonifera Huds.), which most often is associated with golf courses. Synthesis of ligneous and phenolic compounds by plants requires adequate Mn+2 and Cu+2 nutrition and may be a factor in disease resistance. An experiment was conducted on a creeping bentgrass fairway naturally infested with Gga to determine if foliar applications of Mn+2 (1.02 and 2.04 kg·ha–1 per application) and Cu+2 (0.68 kg·ha–1 per application) would reduce take-all severity. Prior to initiating treatments, soil pH was 6.4 and Mehlich-3 extractable Mn+2 and Cu+2 were 5 mg·kg–1 and 1.7 mg·kg–1, respectively. Manganese and copper sulfate treatments were initiated in July 1995 and foliarly applied every 4 weeks through 1997 with the exception of December, January, and February. Disease incidence was decreased from 20% on untreated turf to 5% with the high rate of MnSO4. For both years, turf treated with the high rate of Mn+2 had less disease than turf receiving the low rate of Mn+2. The application of CuSO4, however, did not influence disease development.

Abstract:
Single point incremental forming has attracted the interest of researchers in the last decade for the production of prototypes and small batch production of sheet-based parts [1, 2]. This technique allows the manufacture of parts without using expensive die sets. The SPIF (Single point incremental forming) process can be performed on different equipments such as adapted CNC milling machines, serial robots and built proposed machines [3]. Every solution has advantages and disadvantages. This work presents the CAD/CAM strategies for a parallel kinematics SPIF machine, designed and built at the University of Aveiro [3]. This machine brings a new approach to the SPIF industry. The machinery used to perform SPIF operations has limitations in their work volume with limited movements and in the magnitude of applicable forces. With that in mind, this machine was projected to overcome that obstacle, and was provided with a system with 6 degrees of freedom, while maintaining the ability to apply high loads. The disadvantage is the increase in volume occupied by the kinematic system. The manufacture of new parts could be reached out with more flexibility on the chosen tool path. The first step is the product design in the commercial CAD system. Next step is generating the tool path of the forming tool. This step is very important to achieve the desired part shape. It is used a commercial CAM system (EdgeCAM 2012®), which has resources from three up to five axis strategies. The last step is to send the information to the machine’s control system, based on real-time software. This paper will describe each step with more details.

Abstract:
An unknown disease was observed in June 2002 and 2003 on creeping bentgrass (CRB [Agrostis stolonifera L.]) putting greens at The Country Club of Landfall in Wilmington, NC that were established in 2001 with a 1:1 blend of cvs. A-1 and A-4. Soil pH ranged from 7 to 8 at this location because of poor quality irrigation water. Symptoms appeared in circular patches of 0.3 to 1 m in diameter that exhibited signs of wilt followed by chlorosis and orange foliar dieback. The disease was initially diagnosed as take-all patch caused by Gaeumannomyces graminis (Sacc.) Arx & D. Olivier var. avenae (E.M. Turner) Dennis, based on the observation of necrotic roots and crowns that were colonized with dark, ectotrophic hyphae. However, the historical lack of take-all patch occurrence in this region led to the suspicion that G. graminis var. avenae was not involved. Sections of root and crown tissue were surface disinfested in 0.6% NaOCl for 5 min or 1% AgNO3 for 1 min and 5% NaCl for 30 s. Tissue was plated on SMGGT3 (2) or on potato dextrose agar containing 50 mg L-1 of tetracycline, streptomycin, and chloramphenicol. A fungus resembling Magnaporthe poae Landschoot & Jackson was consistently obtained regardless of isolation method. Teleomorph production was conducted on Sachs agar (4) overlaid with autoclaved wheat (Triticum aestivum L.) stem sections. Seven isolates were plated alone or paired with M. poae tester isolates 73-1 or 73-15 (3) and incubated at room temperature under continuous fluorescent illumination. Six isolates produced perithecia and ascospores typical of M. poae (3) when paired with 73-15 but not when plated alone or paired with 73-1; these isolates are, therefore, M. poae mating type ‘a’. Isolate TAP42 did not produce perithecia and remains unidentified. Cone-Tainers (3.8 × 20 cm) containing calcined clay were seeded with ‘A-4’ CRB (9.7 g cm-2) and inoculated 8 weeks later by placing four M. poae-infested rye (Secale cereale L.) grains below the soil surface. Inoculated Cone-Tainers were placed in growth chambers with 12-h day/night cycles at 30/25°C, 35/25°C, or 40/25°C. Field plots (1 m2) of ‘A-4’ CRB in Jackson Springs, NC were inoculated on 19 June 2003 by removing a soil core (1.9 × 10.3 cm) from the center of each plot, adding 25 cm3 of M. poae-infested rye grains, and then capping the hole with sand. Growth chamber and field inoculations were arranged in a randomized complete block with four replications. Eight weeks after inoculation in the growth chamber, isolates TAP35, TAP41, and SCR4 caused significant foliar chlorosis and dieback at 12-h day/night cycles of 30/25°C and 35/25°C, but only TAP41 induced symptoms at 40/25°C. Isolate TAP42 did not induce symptoms at any temperature regimen. Orange patches (10 to 15 cm in diameter) were observed in field plots inoculated with TAP41 on 27 August 2003. No other isolates induced aboveground symptoms. Roots and crowns of plants exhibiting foliar symptoms in the greenhouse and field were necrotic and colonized with ectotrophic hyphae, and M. poae was consistently isolated from this tissue. Although M. poae has been associated with CRB in Florida (1), to our knowledge, this is the first report of summer patch of CRB within the normal zone of adaptation for this turfgrass species. Observation of this disease highlights the need for accurate methods for diagnosis of diseases caused by ectotrophic root-infecting fungi. References: (1) M. L. Elliott. Plant Dis. 77:429, 1993.

Abstract:
Single Point Incremental Forming (SPIF) given its easy implementation and absence of dedicated tooling is a promising manufacturing technology concerning the production of customized products, low batches or prototyping of ready-to-use parts. The range of application is wide, covering many materials and virtually unlimited geometries. Indeed, current process boundaries are more related to machine limitations than to the procedure itself. In this paper, research is carried out on the state-of-the-art of existing SPIF machine technology, in order to determine an appropriate configuration for an incremental forming equipment that overcomes such limitations. A comparative analysis is carried out to evaluate the different types of currently used equipment: adapted milling machines, serial robots and purpose built machines. Comparison parameters include among many others the maximum payload, tool path flexibility, stiffness and overall cost of the machine, based on information gathered on publications mainly from the last decade. Alternatively, other solutions used for different technological processes and assembly operations, such as precision positioning, are also taken into account. Based on the comparison of all solutions, and on the objectives of the current project carried out at the University of Aveiro, it is concluded that an equipment with parallel kinematics, driven by hydraulic servo-cylinders, could be the best choice to achieve the established goals.

Abstract:
In recent years, Qualitative Comparative Analysis (QCA) has emerged as a research approach to get insight into social science and business complexity. In contrast to the inferential methods that measure the net effect of an independent variable into a dependent variable, the QCA approach uncovers the necessary and sufficient conditions leading to a desired outcome. This paper discusses complexity in social science and business from the QCA perspective. In this regard, there are three streams of literature in strategic management aiming to explain how some firms outperform others: Porter´s competitive advantage approach, Barney´s sustained competitive advantage perspective, and D´Aveni´s temporary advantage. However, the sustained competitive advantage approach suggests that generating economic rents must be understood as a complex phenomenon characterised by three features: i) path dependency (e.g., some resources and capabilities can only be developed over long periods, ii) social complexity (e.g., it may not always be clear how some firms develop some capabilities in short to medium term), and iii) causal ambiguity (e.g., some resources and capabilities cannot be bought and sold in markets). Therefore, this framework draws from a complex (or complexity) process that establishes logical connections between combinations of causal conditions (i.e., resources and capabilities) and a desired outcome (i.e., economic rents). The research methodology for business from the QCA perspective thus may raise some critical questions: How do some firms accumulate and deploy resources and capabilities more efficiently than their competitors to internally (not in markets) acquire and sustain a competitive advantage? And what is the nature of a firm´s economic rents? In short, this paper discusses the nature of sustained competitive advantage (i.e., desired outcome) as a complex process (and not as a linear process) in that some firms outperform others, managing and deploying different resources and capabilities (i.e., conditions).

Roberts, J. A., L. P. Tredway, and D. F. Ritchie. "First Report of Xanthomonas translucens Causing Etiolation on Creeping Bentgrass Turf in Illinois, Kentucky, and North Carolina." Plant Disease 98, no. 6 (June 2014): 839. http://dx.doi.org/10.1094/pdis-05-13-0565-pdn.
Abstract:
Symptoms of etiolation, which is an abnormal elongation and yellowing of tillers, have been observed on creeping bentgrass [Agrostis stolonifera L. (CBG)] putting greens for decades; however, symptoms are typically transient and non-problematic. Reports of etiolation have become more frequent recently and research supports the involvement of bacteria (1). During stressful summer periods in 2011 and 2012, 62 CBG putting green samples were submitted to the NCSU Turf Clinic exhibiting symptoms of etiolation, chlorosis, and/or general decline. Microscopic examination of stem and leaf tissue often showed bacterial streaming from the xylem tissue. Symptomatic tissue was surface disinfested in sodium hypochlorite (10% Clorox) for 5 min, blotted dry, and rinsed in sterile dH2O. Disinfested tissue was placed in a small drop of sterile dH2O on a glass microscope slide and cut to allow bacteria to stream into the water for 2 min. The resulting bacterial suspension was streaked onto three nutrient agar (NA) plates and incubated at 30°C overnight. Bacterial colonies varied in morphology and those present in the greatest number based on morphology were re-streaked to isolate individual colonies. Bacterial isolates were tentatively identified to species using rDNA sequencing of 16S and ITS regions (3). Sequencing results showed isolates obtained from 6 locations (in Illinois, Kentucky, and North Carolina) having a positive match (≥99% 16S and ≥93% ITS) to Xanthomonas translucens (GenBank accessions AY572961, HM181927, JX976312, AY253329, and AB680445). Additional research is needed to confirm pathovar designation as X. translucens isolates were similar to both poae and graminis pathovars. A representative isolate (LW10-12A) was also examined for carbon source utilization using the BIOLOG 3rd Gen Microplate (Biolog Inc., Hayward, CA) resulting in a positive identification of X. translucens. Isolate LW10-12A was used to inoculate 6-week-old seeded creeping bentgrass cv. A1 plants maintained at 1 cm height in 3.5 cm diameter containers. Scissors were dipped in a cell suspension (~109 CFU ml−1 in sterile dH2O) and used to cut healthy CBG plants at 1 cm height and the remaining suspension was applied to the foliage until runoff using an atomizer bottle. Non-inoculated plants were cut and misted using sterile dH2O. After inoculation, plants were placed in a sealed clear plastic Camwear container (Cambro Co., Huntington Beach, CA) for 48 h and then transferred to the growth chamber bench (30°C) receiving irrigation twice daily with dH2O. Etiolation was rated within each of the four replicates by counting the number of etiolated leaves that were easily observed as significantly higher than the rest of the turf canopy. Plants inoculated with X. translucens exhibited etiolation of the youngest leaf within 48 h, whereas the non-inoculated plants did not. Symptoms were similar to observations in the field, as etiolated leaves were chlorotic and easily extracted from the turf surface. Microscopic examination showed bacterial streaming and identification of bacteria, using the previously described methods, was positive for X. translucens. Etiolation symptoms persisted over multiple weeks, but a decline in turf quality was not observed. Etiolation has been previously suggested as a precursor to bacterial wilt, caused by X. translucens pv. poae, on annual bluegrass [Poa annua L. f. reptans (Hausskn) T. Koyama] (2) and Acidovorax avenae has also been shown to produce etiolation on CBG (1). To our knowledge, this is the first confirmation of X. translucens as a cause of etiolation in CBG.

Abstract:
L’orientation des collégiens en milieu rural est généralement perçue sous le régime de la contrainte. Il est vrai que ces adolescents choisissent, davantage que les jeunes urbains, des formations courtes via les voies professionnelles, ce que la littérature attribue à un ensemble de causes : un modèle d’orientation prévalent dans les familles populaires, des exemples de possibles moins diversifiés, des possibilités de formation plus rares et plus éloignées, nécessitant une mobilité à laquelle toutes les familles ne peuvent consentir.Considérant d'emblée une pluralité d'espaces ruraux plus qu'un milieu homogène ou résiduel, ce travail tente de mesurer, outre ces différents facteurs, le pas à pas de la construction des choix opérés sans perdre de vue le poids des collèges eux-mêmes, par une approche essentiellement qualitative associée à des données statistiques. Si le milieu social des jeunes, surtout le diplôme de la mère, induit les demandes d’orientation des adolescents, le caractère socialement situé de ces demandes peut être accentué par les pratiques en cours dans les établissements en matière d’éducation à l’orientation et d’orientation proprement dite, différentes d’un collège à l’autre. Mais il peut également être modulé par les loisirs et les sociabilités amicales et familiales des adolescents, qui y découvrent des pratiques ainsi que des exemples de possibles de formations et de professionsRural Secondary School children’s “Further Education” choices and career plans are generally seen as being an almost forced decision. It would not be wrong to say that Secondary School leavers from rural areas tend to choose shorter, professionally based courses which experts put down to several specific reasons. First, families from a working-class background have a mindset tending towards the idea that the options available are more limited and that the possible “Further Education” courses are therefore rarer and further away from the family environment. Some families are not prepared to accept this imposed, educational mobility. The starting point for the following analysis takes into account the obvious notions that there is not a homogenous rural community but rather a variety of rural areas and working-class families. Considering these elements, this thesis tries to measure the step-by-step processes which lead to the decisions made for post-Secondary Education. The influence of Secondary Schools must also be considered in the essentially qualitative approach which includes the input given by statistical evidence. If the Social Class origins, especially the mother’s educational achievement level, can explain, for a large part, the choices made by students at the end of Secondary School ; this analysis must also take note of the professional and social level of the schools’ catchment area. Thes factors can be accentuated both by the Careers’ Advice available and the actual results of post Secondary School decisions, prevalent in each Secondary School. These influencing factors and the differences subsisting between each School are also important in each Educational Community’s way of apprehending Careers Advice and the decisions made by their pupils. Other reasons are also to be included, such as leisure time activities as well as peer pressure and influence of each family environment. These sociability factors can also contribute to the discovery of new Careers and Further Education possibilities

Abstract:
Mestrado em Toxicologia e EcotoxicologiaHuman exposure to polycyclic aromatic hydrocarbons (PAHs) can arise from forest fires, coal tar combustion, vehicle exhausts and tobacco smoke and can be critical in some residential and working areas. PAHs are considered a group of priority chemicals as they are carcinogenic, mutagenic and teratogenic. Therefore, is crucial to monitor and study human exposure to PAHs, namely during fetal development, which is considered a sensitive window of exposure to contaminants. In this context, the main objectives of this study were: (i) to assess maternal and fetal exposure to PAHs in parturient from the Aveiro region using samples of placenta and blood as biological matrices; (ii) to examine the influence of environmental, sociodemographic, lifestyle and smoking habits that may contribute to PAHs exposure during pregnancy in Aveiro region, Portugal. This study was performed in 49 mother/newborn pairs from Aveiro region. All the matrices sampled (placenta, umbilical cord blood and mothers’ blood) and information gathered was approved by Ethics Committee of Infante D. Pedro Hospital in Centro Hospitalar do Baixo Vouga, Aveiro and all the parturient previously signed an informed consent. A fluorescence spectrophotometer was used to quantify levels of PAHs (naphthalene, phenanthrene, pyrene and benzo[a]pyrene equivalents) in the tissues collected. In general, the studied group presented high levels of PAHs equivalents in the placenta (total homogenate fraction) and low levels in the umbilical cord blood. The low molecular weight PAHs (naphthalene and phenanthrene equivalents) measured in placenta presented higher levels than high molecular weight PAHs (pyrene and benzo[a]pyrene equivalents). Considering the county of residence, the highest PAHs levels in placenta were found in parturient from Aveiro, Ílhavo and Albergaria-a-Velha and the lowest in Águeda. Moreover, increased levels of naphthalene and phenanthrene equivalents were associated with mothers’ exposure to vehicle exhaust, while high levels of benzo[a]pyrene equivalents were associated with their exposure to tobacco smoke at work. The highest levels of naphthalene, phenanthrene and benzo[a]pyrene equivalents were found in homogenized placenta of mothers who smoked in the third trimester of pregnancy. No significant correlations were found between levels of PAHs equivalents present in biological tissues studied and anthropometric data of newborns, but in general, high PAHs levels were found in newborns groups with low weight, head circumference, and length. This work provided an overview of the PAHs levels on pregnant woman from the Aveiro district, identifying the main sources of exposure to PAHs. Furthermore, placenta do accumulate PAHs, but is not a complete barrier for those lipophilic compounds, since they seem to cross cell membranes reaching umbilical cord blood and potentially causing adverse effects in the newborns, such as, low weight, length and head circumference values, despite the lack of statistical significance.
A exposição humana a hidrocarbonetos aromáticos policíclicos (HAPs) pode advir de fogos florestais, combustão proveniente do carvão para fazer alcatrão, fumo do tabaco e fumo proveniente de tráfego rodoviário, podendo torna-se crítica em algumas áreas de residência ou tipos de trabalho. Os HAPs são considerados um grupo de químicos prioritários uma vez que são carcinogénicos, mutagénicos e teratogénicos. Portanto, é crucial monitorizar e estudar a exposição de populações humanas a HAPs principalmente durante o desenvolvimento fetal, que é considerada uma fase maís sensível à exposição a contaminantes. Neste contexto os principais objetivos deste estudo foram: (1) avaliar a exposição de HAPs nas parturientes e recém-nascidos da região de Aveiro usando como matrizes biológicas sangue e placenta; (2) examinar a influência ambiental, dados sociodemográficos, estilo de vida e hábitos tabágicos que podem contribuir para a exposição dos HAPs durante a gravidez na região de Aveiro, Portugal. Neste estudo participaram 49 mães e recém-nascidos da região de Aveiro. A amostragem efetuada (placenta, sangue do cordão umbilical e sangue das parturientes) e informações recolhidas foram aprovadas pelo Comité de Ética do Hospital Infante D. Pedro do Centro Hospitalar Baixo Vouga, Aveiro e todas as parturientes assinaram previamente consentimento informado. Foi utilizada espectrofotometria de fluorescência para efetuar a quantificação dos HAPs (homólogos de naftaleno, fenantreno, pireno e benzo[a]pireno) nos tecidos recolhidos. Em geral o grupo estudado apresentou elevados níveis de HAPs na placenta (fração total homogeneizada) e os níveis mais baixos no sangue do cordão umbilical. Os HAPs de baixo peso molecular (homólogos de naftaleno e fenantreno) que foram medidos na placenta, apresentaram níveis mais elevados que os níveis de HAPs de elevado peso molecular (homólogos de pireno e benzo[a]pireno) encontrados na placenta. Considerando o local de residência, os níveis de HAPs mais elevados na placenta foram encontrados em parturientes que habitavam em Aveiro, Ílhavo e Albergaria-a-Velha e os níveis mais baixos em Águeda. Além disso, o aumento dos níveis de homólogos de naftaleno e fenantreno na placenta foram associados à exposição a fumo proveniente de tráfego rodoviário e os elevados níveis de benzo[a]pireno foram associados com a exposição a tabaco no trabalho. Os níveis mais elevados de homólogos de naftaleno, fenantreno e benzo[a]pireno foram encontrados na placenta (fracção homogeneizada total) de parturientes que fumaram no terceiro trimestre de gravidez. Não foram porém encontradas correlações significativas entre os níveis de HAPs e os dados antropométricos dos recém-nascidos, mas foram em geral encontradas elevadas concentrações de HAPs em recém-nascidos com menor peso, perímetro cefálico e comprimento. Este projeto permitiu obter uma visão geral dos níveis de HAPs em parturientes do distrito de Aveiro, identificando as principais fontes de exposição a HAPs. Para além disso, verificou-se que a placenta acumula HAPs, mas não funciona como uma barreira total a estes compostos, uma vez que estes conseguem alcançar o sangue do cordão umbilical, podendo como tal vir a causar efeitos adversos nos recém-nascidos.

Abstract:
In this chapter, the author shares his journey, traversing different paths that take us from Broad Street to Locust Street, from Pattison Avenue to City Line Avenue, all the way to Bethlehem. His story reveals a kaleidoscopic nocturne, “the story of Philadelphia after sunset, of the fan life that on-field cameras cannot capture.” It is the portrait of a massive, eclectic community and some of its many sporting passions. The author compares the attitudes of Philly sports fans during the day and at night, claiming that he has walked among these fans for forty years, witnessed their soft side, the night face they rarely show the world. The author concludes by describing the city of Philadelphia from evening to dawn.

In Computational Design and Robotic Fabrication, 466–75. Singapore: Springer Nature Singapore, 2024. http://dx.doi.org/10.1007/978-981-99-8405-3_39.
Abstract:
AbstractSteel reinforced concrete is a widely used material for constructing large spanning planar building elements due to its strength, durability, and low cost, but its environmental impact, long fabrication time, and relatively low structural performance demonstrate the need for innovation. To address these issues, this study proposes a novel design methodology and fabrication method that integrates robotic Fibre Reinforced Polymer (FRP) woven reinforcement that is optimized using a Multi-Weight Bi-directional Evolutionary Structural Optimization (MW-BESO) algorithm. The optimized FRP reinforcement is then cast in epoxy resin to produce the large scale planar building element. The methodology is evaluated through a Tabletop prototype and other small-scale rapid prototypes, which demonstrate the successes, challenges, and limitations of this approach. The study outlines the material and methodological testing conducted to assess the effectiveness of using the MW-BESO algorithm with robotic FRP weaving and describes the workflow of transforming the resulting 3D MW-BESO geometry into a 2D robotic winding path for fabrication. The research shows that this methodology has the potential to reduce the environmental impact, stimulate innovative design solutions, and streamline the fabrication of large scale building elements, providing a promising avenue for the development of sustainable and efficient construction techniques.

Abstract:
Abstract Shakespeare’s life began near the reflecting, gleaming river Avon, which today flows past Stratford’s Church of the Holy Trinity where he lies buried, and past a theatre where his dramas are seen and heard by visitors from all nations. In rare flood times, the river was wild and destructive, sweeping away bridges and much in its path, but normally it was hospitable to truant boys or patient fishermen, and no guttered rocks or congregated sands imperilled any large keel here. The river arises in grassy highland in the east of England near Naseby, and for miles hardly deserves the name Avon, or ‘river’, which has echoes all over Celtic Europe: the Avon or Aven in Brittany, the Avenza in Italy, and the Avona in Spain. This Avon is at first only a runnel and then a willow-bordered stream,

Abstract:
In pursuit of global climate goals, the emergence of a hydrogen economy is a promising avenue, emphasizing the environmentally friendly production and versatile applications of hydrogen as an energy carrier, raw material, and cornerstone for energy-intensive sectors such as power, transportation, and especially the chemical industry. This evolution requires profound changes in the supply chain, ranging from the establishment of a robust hydrogen infrastructure to the realization of efficient transportation, distribution, and storage mechanisms. Amidst a plethora of potential hydrogen supply modalities, determining the path to a carbon-neutral hydrogen economy presents complex challenges. This chapter explores these transition complexities in the context of sustainable technology development. It also critically assesses the symbiosis between this transition and emerging carbon supply chains, particularly those aiming for closed carbon cycles, and presents a holistic vision for future sustainable frameworks in the chemical sector.

Abstract:
Abstract The recent burgeoning of interest in the analysis of nineteenth-century sonata forms under the aegis of the so-called New Formenlehre has opened up new avenues of research for scholars of Brahms’s music. Taking its bearings especially from the work of James Webster and William Caplin, this chapter explores one such avenue, by applying a systematic, corpus-based methodology to the study of first-theme syntax in Brahms’s first-movement sonata forms. The chapter develops a categorical framework for theorizing Brahms’s thematic syntax, before addressing in detail the compositional choices that characterize Brahms’s paths from thematic initiation to closure.

Abstract:
New types of companies have emerged, known as “Born Globals” (BGs), transitioning and internationalizing early and rapidly. They have attracted scholarly interest because their involvement in international sales from the moment of inception contradicts the more traditional perspectives on internationalization. This chapter explores a gap in the literature on BG micro-enterprises' behavior on their internationalization trajectory. It analyzes the case of a micro-company based in Aveiro, Portugal that follows a passive internationalization path to embrace a BG's typical behavior. The behavior of this micro-company is examined to illustrate how a BG can find new opportunities abroad and take advantage of them, the main entry modes and marketing strategies adopted in the early and rapid internationalization process, the importance of networking and growth strategies, and the role of the CEO in the internationalization process. This chapter adds value by explaining how a micro-enterprise manages to overcome its passive behavior and evolve into a BG company.

Abstract:
Practices and commitments which lie at the heart of what has come to be referred to as Receptive Ecumenism can also be seen to lie at the foundations of the communities of Jesus followers in the first century CE. The desire for communion (koinonia) among Jesus followers finds its practical expression throughout the New Testament. This chapter explores two examples: (1) in the Letter to the Colossians, addressed to divided gatherings of Jesus households in Colossae and Laodicea, a particular avenue of ‘reception’ by which communion between these two communities is enhanced and division overcome is explored, highlighting essential qualities or virtues which Jesus followers are invited to emulate; (2) in Acts 6:1–7, two religiously divided Jerusalem groups overcome their divisions and experience communion (koinonia). In a discernment of how to address division and to receive the ‘other’, the leaders of Jerusalem’s Jesus followers return to a path of communion founded on discernment of God’s word. Both examples from these first-century communities of Jesus followers reveal concrete engagement, practical hospitality, and ecclesial growth which can speak into our own journey in Receptive Ecumenism.

Abstract:
This chapter discusses the washed-up plastic Christmas tree at the corner of Jersey Avenue and Shore Road which became a national icon representing “Jersey Strong.” It narrates how James Butler used social media as so many did in those weeks following the storm: to connect, to process, to help, and to grieve. What followed over the next two hours were nearly two dozen separate posts, a series of discrete observations and reflections from his night of helping families sift through their lives. The chapter emphasizes that the Union Beach Hope Tree became a symbol of the Sandy recovery. Butler's efforts emerged as part of a coalescing network of individual homeowners, volunteer coordinators, and relief workers coming together to respond to the immediate needs of Bayshore residents. Filling the gaps in the official recovery efforts, the chapter stresses that the informal infrastructure mitigated the effects of the storm for the most vulnerable and formed a critical support base at ground zero of Sandy's destructive path. In what seemed to so many like a profound vacuum of leadership, this collaborative spirit of voluntarism forged deep and lasting connections.

Abstract:
Abstract With the Prime Minister’s call to make India— a self-reliant nation, one of the key pillars for achieving the same is a stable policy and regulatory environment. Viewing taxes from the perspective of an avenue for mobilizing revenue to facilitate public expenditure would rather be a narrow outlook than building a transparent taxation policy that is able to encourage and woo businesses and corporations to set up shop in India, thereby promoting domestic manufacturing and production, employment opportunities and propelling the country into the path of economic growth. Tracing back history, it can be seen that the mindset of policymakers had witnessed a sea change since the beginning of the 1990s. The outcome of major changes in the tax regime has shown positive results in terms of cost of production, leading to horizontal expansion of standard of living; price stability and acceleration in growth rates. The chapter discusses how transparency in taxation is equally important and the current government with its approach of ‘Minimum Government and Maximum Governance’ and ‘Reform, Perform and Transform’ has been initiating measures in this context. It also delves into the simplification of GST in detail, recommends bringing petroleum products under GST and discusses the adverse impact that the retrospective tax has had on the business environment.

Abstract:
Accounts of the early modern public sphere are characteristically focused on its critical, political functions—imagining it as a sphere of agonistic performativity, of rational-critical debate, or of public opinion being shaped in an effort to generate political pressure, for example. Politics in all these contexts is understood as an engagement with matters of common concern: what is public and what is political are not only inseparable but also close to being synonymous notions. But parallel with the rise of the early modern public sphere(s) and of the political universe implied by it, politics, political activity also began to emerge as a career path: statecraft, an avenue of political mobility through employment and office, which presupposed a body of knowledge, a competence acquired through training, rather than a mere entitlement by birth. This chapter explores the consequences of this development for diplomacy. From the late sixteenth century onwards, information about foreign polities—including both diplomatic writing and political news from abroad—was entering public circulation in manuscript as well as in print. Plays performed on the public stage were also clearly interested in foreign political developments. Such diplomatic knowledge in public circulation is best understood as a form of cultural capital, whose value is partly constituted by its association with activities and competences that were of considerable social prestige, and partly by the restrictions on its circulation.

In Chaos and Complexity Theory for Management, 63–87. IGI Global, 2013. http://dx.doi.org/10.4018/978-1-4666-2509-9.ch004.
Abstract:
The interrelationship between stock and commodity markets has been an issue of interest for both the academia and practitioners in the field of investment and wealth management. Traditionally, commodity has been a popular avenue for diversification in a mixed portfolio. However, this works well as long as there is little or no correlation between the two markets. This chapter presents an empirical investigation of the daily movement of stock and commodity index of two different countries to throw some light on the interrelationship between stock and commodity market. The uniqueness of this study lies in the choice of markets as also the methodology. The authors have chosen a developed market, viz., the US market, and an emerging market, viz., the Indian market. This study uses the major stock and commodity indices respectively for both countries for a period of three years. For analysis the authors have used the tools from nonlinear dynamics like recurrence analysis, power spectrum analysis, and delay based cross-correlation function. The investigation revealed that the dynamics of the time path of daily movement of Indian stock and commodity exchanges are much similar in nature while those of the US market are quite different. This chapter also models the respective time series using Geometric Brownian Motion and finds that the Indian data set performed much better than the US ones. This has a strong impact on strategy for designing mixed portfolios in Indian market.

Abstract:
This article investigates the morphological and functional changes of Chucri Zaidan avenue and its relationship with the new axis of urban centrality of São Paulo, also composed of Berrini Avenue. The study seeks to reveal the construction logics and the process that has been transforming the area into a financial center and condenser axis of a mixture of uses, including leisure activities, services, commerce and culture that enrich the social life of the area. To study it, we will seek to identify the main urban transformations that have occurred throughout history, drawing the changes that have occurred at the ground level, the building typology, the uses and contours of public and collective spaces. The analyses will be based on official documents, drawings drawn from registration maps of the city, on data collected on site, and on the theoretical discussion about the way as a powerful element of condensation of collective spaces and their centrality and urbanity. As a result, it is verified that the axis is constructed as a linear centrality, through the implementation of mixed-use buildings, with predominance of office buildings, implanted in partially open blocks configured with paths and permeable free areas, with a wide offer of green areas. On the other hand, it lacks social mixing. Keywords: Linear Centrality, Collective Spaces, Metropolis of São Paulo, Urban life. Este artigo investiga as mudanças morfológicas e funcionais da avenida Chucri Zaidan e sua relação com o novo eixo de centralidade urbana de São Paulo, composto também pela avenida Berrini. O estudo busca revelar as lógicas de construção e os processos que vem transformando a área em centro financeiro e eixo condensador de atividades de lazer, serviços, comércio e cultura que enriquecem a vida social da cidade. Para estudá-la, buscaremos identificar as principais transformações urbanas que ocorreram ao longo da história, desenhando as mudanças transcorridas na tipologia edificada, nos usos e contornos dos espaços públicos e coletivos. As análises serão embasadas por documentos oficiais, desenhos elaborados a partir de mapas cadastrais da prefeitura, dados coletados in loco, bem como na discussão teórica sobre a via como elemento estruturador dos espaços coletivos e de sua centralidade e urbanidade. Como resultado, verifica-se que este eixo se constrói como uma centralidade linear, mediante a implantação de edifícios de uso misto, com predominância de edifícios de escritórios, implantados em quadras parcialmente abertas configuradas com caminhos e áreas livres permeáveis, com ampla oferta de áreas verdes. Por outro lado, é carente de mistura social. Palavras-chave: Centralidade Linear, Espaços Coletivos, Metrópole de São Paulo, Vida urbana.

Abstract:
<p>The Grand Avenue Pedestrian Bridge spans 85m from a park and residential neighborhood to a developing waterfront district that is 24m below. The bridge carries sewer, storm, and water utilities over rail lines and a highway while passing under power lines. The bridge’s east landing is on a landslide prone steep slope. On the west the bridge lands on a new concrete stair and elevator tower that rests on soil that is regularly infil- trated with seawater.</p><p>The design concept uses the constraints of the project to create a unique moment that is both utilitarian and unexpected. By sloping the truss to drop 4.8% towards the west, a set of accessible ramps are created on the top, side, and interior of a box-truss style bridge. Traversing 7m of elevation through accessible paths allowed the design team to minimize the height of the elevator and therefore moment into the foundations, critical for a site that is seismically active and located in seawater infiltrated soil.</p><p>Material choices for the bridge and throw barrier were based on considerations of durability and mainte- nance. Weathering steel is used for the primary truss members, painted steel for members located under the deck, and bare aluminum panels with a custom CNC cut perforation form the guardrail and throw barrier. All of the elements come together as a unified experience.</p>

Abstract:
This study aims to investigate the efficacy of a vlog-based teaching model in enhancing oral speaking skills and engagement among university students in an English as a Foreign Language (EFL) setting. With the digital technologies reshaping educational methodologies, this research integrates vlogs (video blog) into EFL teaching to build a more engaging learning path. The study was conducted over a semester with 30 university EFL learners in China, employing a mixed-methods approach to evaluate the impact of vlog-based learning. Pre-and-post oral speaking tests were administered to assess improvements in students' language proficiency, while questionnaires measured levels of engagement and motivation. Initial findings suggest that the vlog-based teaching model significantly improved students' speaking skills and heightened their engagement in learning English, indicating a promising avenue for digital media integration in language education. This paper contributes to the evolving field of digital media in EFL teaching, offering insights into the potential of vlogs to enrich language learning experiences and outcomes.

Abstract:
Abstract Backside silicon removal provides an avenue for a number of modern non-destructive and circuit edit techniques. Visible light microscopy, electron beam microscopy, and focused ion beam circuit edit benefit from a removal of back side silicon from the integrated circuit being examined. Backside milling provides a potential path for rapid sample preparation when thinned or ultrathinned samples are required. However, backside milling is an inherently destructive process and can damage the device function, rendering it no longer useful for further nondestructive analysis. Recent methods of backside milling do not guarantee device functionality at a detected end point without a priori knowledge. This work presents a methodology for functional end point detection during backside milling of integrated circuit packaging. This is achieved by monitoring second order effects in response to applied device strain, which guide the milling procedure, avoiding destructive force as the backside material is removed. Experimental data suggest a correlation between device power consumption waveforms and second order effects which inform an in situ functional end point. Keywords: functional end point, side-channel analysis, backside thinning, milling, machine learning, second order effects

Abstract:
The U.S. Army Combat Capabilities Development Command's (CCDC) Aviation Engineering Directorate's Maintenance Engineering Division provides maintenance engineering support to a variety of Army aircraft systems. The Maintenance Engineering Division has historically supported overhaul, repair and maintenance functions for Army rotary aircraft, but has recently unveiled an avenue of opportunity to support Army unmanned aircraft system platforms as well. The Army's leading unmanned system is the MQ-1C, more frequently referred to as the Gray Eagle. The Maintenance Engineering Division assumed sustainment support of this system post production and deployment phase in the program lifecycle and has had to overcome several obstacles in that process. Even though the Army has provided sustainment support for rotary aircraft for several decades, unmanned aircraft programs in the Army are fairly new territory and a new path was paved to ensure similar sustainment support was provided. Forging this path has proved to be challenging since sustainment support was not well-defined early in the lifecycle even though approximately 70% of program costs are attributed to sustainment efforts on average. Consequently, engineers within the organization were challenged to pursue creative tactics to provide product support to unmanned aircraft in an equivalent manner to manned rotary aircraft, specifically for Gray Eagle Unmanned Aircraft System (UAS) in this report. The intent of this report is twofold; (1) inform the engineering community of the unique challenges of Gray Eagle UAS product support team, from a maintenance engineering perspective, and provide further insight into how they were overcome and (2) increase awareness in the acquisition community of the importance in considering sustainment/maintenance support early in the acquisition lifecycle to prevent technical barriers for a product support team with fielded systems.

In Seminario Internacional de Investigación en Urbanismo. Bogotá: Universidad Piloto de Colombia, 2022. http://dx.doi.org/10.5821/siiu.10031.
Abstract:
In this work we propose to historically analyze the material and symbolic construction of the north bank in the suburban area of the city of Buenos Aires (the coastal path that goes from the vicinity of the Nuñez neighborhood to the town of Tigre) from the spaces for circulation. The investigation will take as a starting point the paved road - or at least some of its sections - that linked the Capital with El Tigre-, inaugurated by the Governor of the Province of Buenos Aires, Mr. Ignacio Darío Irigoyen and Minister Etcheverry as part of the works that were carried out for the celebrations of the Centennial of the May Revolution in 1910. In this way, we are interested in accounting for the existence of a link between the city and the northern suburb that was defined during the first decades of the century XX. How did this waterfront take shape in relation to mobility practices? What type of activities characterized the localities that made it up? What kind of image was built on that territory? In the 1920s, a project arises to build a coastal avenue to join the Capital with the town of Tigre, considering the topography of the land, the link with the river and the popularity that it was acquiring as a relatively close place of relaxation and recreation. to the capital.Although this project did not materialize in a coastal avenue, we consider it a relevant element when thinking about the image built on the riverside towns of the north of Buenos Aires. Now, in terms of connectivity, the space for the “good circulation” of automobiles was made on a trace some 20/25 blocks away from the coast that was only consolidated between the decades of 1950-1960 with the construction of the North access, branch Tiger. A branch that in terms of the project recovers that picturesque suburban image of low houses, green spaces where space for speed and walking are combined.From the use of historical sources such as mass circulation magazines, local tourism promotion guides, maps, urbanization projects and the development of road works, we are interested in analyzing the relationship between these first projects and mobility infrastructure works for the area of the north bank and the construction of a picturesque suburban landscape.In these terms, from a historical perspective that allows us to take a broad temporality, we argue that these incipient milestones (projects of particular routes and mobility infrastructures not necessarily developed) gained relevance in shaping the suburban image built on this space of the GBA .Keywords: mobility, suburbs, lightning tourism, North of Buenos AiresThematic block: Theory and History of the city En este trabajo nos proponemos analizar históricamente la construcción material y simbólica de la ribera norte en el área suburbana de la ciudad de Buenos Aires (el trayecto costero que abarca desde las inmediaciones del barrio de Nuñez hasta la localidad de Tigre) a partir de los espacios para la circulación. La investigación tomará como punto de partida el camino pavimentado – o por lo menos algunos de sus tramos- que unía a la Capital con el Tigre-, inaugurado por el Gobernador de la Provincia de Buenos Aires, Señor Ignacio Darío Irigoyen y el ministro Etcheverry como parte de las obras que se realizaron para los festejos del Centenario de la Revolución de Mayo en 1910. De esta forma nos interesa dar cuenta de la existencia de un vínculo entre la ciudad y el suburbio norte que se fue definiendo durante las primeras décadas del siglo XX. ¿Cómo se fue conformando esa costanera en relación a las prácticas de movilidad? ¿Qué tipo de actividades caracterizaron a las localidades que la integraron? ¿Qué tipo de imagen se construyó sobre ese territorio? En la década de 1920, surge un proyecto para construir una avenida costanera para unir la Capital con la localidad del Tigre, ponderando la topografía del terreno, la vinculación con el río y la popularidad que fue adquiriendo como un lugar de esparcimiento y recreación relativamente cercano a la Capital.
Si bien este proyecto no se materializó en una avenida costanera, lo consideramos un elemento relevante a la hora de pensar la imagen construida sobre los pueblos ribereños del norte de Buenos Aires. Ahora bien, en términos de conectividad, el espacio para la “buena circulación” automotor se realizó sobre una traza alejada unas 20/25 cuadras de la costa que recién se consolidó entre las décadas de 1950-1960 con la construcción del acceso Norte, ramal Tigre. Un ramal que en términos de proyecto recupera esa imagen pintoresca suburbana de casas bajas, espacios verdes donde se combinan el espacio para la velocidad y el paseo.
A partir del uso de fuentes históricas como revistas de circulación masiva, guías de promoción del turismo local, mapas, proyectos de urbanización y de desarrollo de obras viales nos interesa analizar la relación entre estos primeros proyectos y obras de infraestructuras de movilidad para el área de la ribera norte y la construcción de un paisaje suburbano pintoresco.
En estos términos, desde una perspectiva histórica que nos permite tomar una temporalidad amplia, sostenemos que estos hitos incipientes (proyectos de trazados particulares y de infraestructuras de movilidad no necesariamente desarrollados) cobraron relevancia en la conformación de la imagen suburbana construida sobre este espacio del GBA.

"Characterization of a Biomechanical Animal Model for Intact Knee Kinematics and ACL Function Using 6-DOF Robotic Technology." In ASME 2011 Summer Bioengineering Conference. American Society of Mechanical Engineers, 2011. http://dx.doi.org/10.1115/sbc2011-53658.
Abstract:
Anterior cruciate ligament injury (ACL) affects an estimated 250,000 people annually [1]. Unfortunately, even with ACL reconstruction, the likely prognosis is long-term osteoarthritis (OA) [2]. Many strides have been made in attempting to understand and improve this outcome. The use of robotic technology has provided an avenue for researchers to examine the ACL’s role in knee joint stability in all six anatomical degrees of freedom (DOF) [3]. The overall goal of our lab robotics research is to use this technology to understand ACL function during activities of daily living (ADLs) in hopes of developing a biomechanical animal model which can be used as a preclinical tool to design new repair methods and materials. We have examined three species (ovine, porcine, and human), measuring all forces and moments produced from displacement control motion paths developed for cyclic testing in a robotic system (KUKA; KR210). This information will provide a basis for comparing intact knee biomechanics and ACL function across species. With these robotic inputs, we have performed a series of studies to aid in the development of a biomechanical model of the human knee.
