La communication entraîneur-athlètes dans deux contextes de karaté.
Creators: name: Larocque, Léon E.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1999
Subjects: subject: Education, Physical.

description: Au cours des deux dernières décennies, un nombre considérable de chercheurs en pédagogie du sport ont étudié le processus enseignement-apprentissage dans la pratique sportive. Dans plusieurs des études rapportées, les chercheurs ont tenté de comprendre l'interaction entraîneur-athlètes en utilisant l'un des trois instruments suivants: les grilles d'observation, les entrevues et les questionnaires. Règle générale, les chercheurs ont accordé très peu d'importance à l'athlète, ce qui est problématique lorsque l'on considère qu'il existe une littérature en éducation qui démontre que l'élève est le lien médiateur dans le processus enseignement-apprentissage. La présente étude a porté sur une composante centrale du processus enseignement-apprentissage: la communication. En suivant une approche inductive, une première phase de la recherche a permis au chercheur de se familiariser avec le contexte de la pratique du karaté et de faire ressortir les éléments qui caractérisaient le plus la communication instructeur-athlètes dans un club de karaté traditionnel. L'analyse des données recueillies lors d'entrevues et d'observations non-participantes a fait ressortir les points suivants: (a) l'adoption des valeurs enseignées, (b) l'importance de l'humilité, (c) la non-valorisation des compétitions et (d) une fixation d'objectifs qui ne correspond pas à ce que l'on retrouve dans la littérature. Afin de répondre aux questions soulevées durant la phase I, des séances d'observation et des entrevues ont été réalisées avec les athlètes débutants du club de karaté et avec les instructeurs et les athlètes d'un programme de sport-études. L'analyse de ce nouveau corpus de données a permis de relever les points suivants: (a) les débutants sont conscients de la philosophie du club, (b) les athlètes débutants ont sensiblement les mêmes objectifs que les athlètes de niveau avancé et (c) dans le programme sport-études, les instructeurs et les athlètes ont des objectifs de performance à des compétitions.

description: Land, energy and water are our most precious resources, but the manner and extent to which they are exploited contributes to climate change. Meanwhile, the systems that provide these resources are themselves highly vulnerable to changes in climate. Efficient resource management is therefore of great importance, both for mitigation and for adaptation purposes. We postulate that the lack of integration in resource assessments and policy-making leads to inconsistent strategies and inefficient use of resources. We present CLEWs (climate, land-use, energy and water strategies), a new paradigm for resource assessments that we believe can help to remedy some of these shortcomings.

Publisher: name: Dipartimento di Lingue e Letterature Straniere Moderne, Università di Bologna
Year: 2009

description: The Brazilian avant-garde movement known as Antropofagia bears, as a birthmark, a paradox: on one hand, it attempted to advance the nationalistic efforts of the Modern Art Week of 1922 (a hundred years after Brazilian Independency). This paper’s goal is to show how some anthropophagic strategies advanced beyond this border dialectics (inside-outside, subject-object, universal-particular, truth-lie), criticizing the notion of mediation (that which limits and directs knowledge.

A Antropofagia modernista brasileira, nasce sob o signo do paradoxo: pretendia, por um lado, avançar no terreno nacionalista aberto pela Semana de Arte Moderna de 1922, concomitante ao centenário da Independência e, por outro, atingir um grau de cosmopolitismo e universalidade. Este artigo propõe ver nas estratégias antropófagas, para além desta dialética de fronteiras (interno-externo, sujeito-objeto, universal-particular, verdade-mentira), uma crítica exatamente da mediação, daquilo que limita e direciona o conhecimento.

Ottawa, une capitale en quête de monumentalité.
Creators: name: Gagnon, Gabriel.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1999
Subjects: subject: Geography.

description: Ottawa's urban morphology has evolved according to the dominating functions of the city. Born from a military building site and shortly after transformed into an industrial center, it is since 1857 Canada's capital. We were interested in the official vocation of this seat of government and to the process that aims at recording its symbolic role into space. In fact, we attempted to see how Ottawa-Hull's political function had materialized, and if, in doing so, the city had become monumental. Rome, Paris and Washington were used as examples of cities where monumentality was expressed. The federal government's interest in planning the capital was revealed as early as the announcement of the Queen's Choice. The governmental intervention was discontinuous, but nevertheless ascending, and culminated with Greber's 1950 report. Noulan Cauchon's importance, an individual little known in Ottawa-Hull's planning history, was revealed in the course of this work. Following the regional authorities' intervention in the 1970's in the national capital region, the federal government has gradually retired its planning initiatives.
Outcomes of isolated and multiple persistent regulatory problems at age 24 months: follow-up of the baby business randomised controlled trial
Creators: name: Tobin, Sherryn
Publisher: name: Swinburne
Year: 2024

description: 503 families reported on their infant's regulatory problems including crying, sleeping and feeding behaviours across the first two years of life. The study found that 46% of infants had one or more persistent regulatory problems, and these problems were associated with poorer child, parent and family functioning. Outcomes were poorer when children had multiple problems. The findings indicate that such problems are common, and it is essential for health practitioners to enquire about infant regulatory problems, as well as parent and family wellbeing, at repeated encounters across the first two years of life.
The use of RADARSAT-1 imagery for lithological and structural mapping in the Canadian High Arctic.

Year: 2000
Subjects: subject: Physical Geography.

description: RADARSAT-1 images of the northern part of Axel Heiberg Island were acquired to define a selection of preferable beam modes for geological mapping in this cold and arid environment with locally rugged topography. Fine, Standard, and Extended High beam mode images with different resolutions, areas of coverage, look directions, incidence angles, and dates of acquisition were analyzed in this study. Major geological contacts in this part of the Sverdrup Basin and the Franklinian Mobile Belt are well identified in these images. Numerous post-Paleozoic tabular intrusive bodies were also identified. Although shadowing and other geometric effects were accentuated, structural features and lineaments were best highlighted in RADARSAT-1 images with higher incidence angles where less topographic displacement is present. Significant seasonal changes in radar image tone associated with localized melting of the active layer were clearly visible between winter and summer images. RADARSAT-1 beam modes were successfully used to make stereo-pairs. (Abstract shortened by UMI.)
The power of heteropolarity and its effects on sexuality educators.
Creators: name: Offman, Alia.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2000
Subjects: subject: Education, Health.

description: Only a limited amount of research has begun to focus on the role of the sexuality educator and how he or she contributes to the curriculum's effectiveness. A review of the literature reveals a tendency within sexuality education to practice what is known as the heteropolar imperative. Heteropolarity is described by Wilton (1985) as the inseparability and co-dependency of gender and the erotic within society; it is the assumption that heterosexuality is natural, proper and right. Heteropolarity is also concerned with the relationship between the biological, the moral, and the ideological in the realm of human sexuality. The current study examines the social forces that effect sexuality educators and limit their curricula to heteropolar imperatives. The study adds to the knowledge base of what is known about the current social control of teachers in their planning and implementation of human sexuality curricula. The study follows a naturalistic research design and involves interviews with five sexuality educators from a variety of organizations in the Ottawa-Carleton region. (Abstract shortened by UMI.)

Communication, complexity and empire: The systemic thought of Harold Adams Innis.
Creators: name: Bonnett, John.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2002
Subjects: subject: History, Canadian.

description: Harold Innis is arguably the most influential social scientist Canada has ever produced. Nearly fifty years after his death in 1952, his writings on Canadian economic history and history of communication technologies are still highly regarded, still widely cited and still viewed as providing an exceptionally powerful framework for interpreting the histories of societies past and present. The problem, however, is that scholars remain uncertain as to the identity of Innis' framework due to his opaque writing style. There is also a sense in the literature that Innis' work on staples is conceptually linked with later studies tracing the impact of communication technology on the rise and fall of empires in the Near East and Europe. But without a clear conception of his framework, the relationship is difficult to assess. Some scholars have questioned whether Innis' work even has an underlying coherence. The purpose of this study is to suggest Innis' work should be construed as a sustained exploration of the nature of economic and social change. His purpose was to resuscitate the dynamic worldview he associated primarily with the writings of Adam Smith and biological disciplines such as ecology and embryology. To interpret Innis, this study uses the most contemporary expression of ecological change, namely that provided by the science of complexity. Through a reading of Innis' writings on staples, Political Economy in the Modern State, and his two major communication studies, this study suggests Innis' description of change contained several persistent features. The first is he studied systems comprised of multiple agents who by virtue of their interaction displayed emergent properties that persist over time. The North Atlantic trading network was one example. Innis also emphasised that his systems were governed by a variable that maintained a proper balance between freedom and constraint. Without it, self-organisation could not occur. In his early work, the variable was transportation. In the later studies, it was the quantity of circulating information. Finally, Innis pointed to systems governed by formal and final cause. They interacted with their surrounding environment to preserve their formal integrity, and regulate the activities of their constituent parts.

description: The artistic and architectonic heritage on the Italian territory is huge. The uniqueness of the goods, their variety and the historical mean are often related to their age and to the environment in which their are located. From this point of view, both historical and architectonic and archeological studies, especially involving churches and religious buildings in general are often aimed at evaluating the architectonic development of the buildings during the centuries, looking for pieces or elements of the previous buildings or part of their structure (floor, graves, walls, etc.). To support historical considerations, could be indispensable to investigate the "dark side" of a building, i.e. to detect the occurrance of caves, underground archeological elements or structures like wall foundations. The Georadar or GPR (Ground Penetrating Radar) system is the most advanced non-invasive technique aimed at searching underground elements and structures, and it can be widely used in the historical and archeological field. This technique allows to get detailed plans including information about the location, depth and size of the objects, goods or rests of them, making it possible, crossing information coming from the existing
plans and the historical, historiographic and archivistic data, to rebuild plans of already forgotten buried structures, helping experts to rearrange the oldest events of Madonna in Campagna in Guanzate is presented, and these techniques have allowed supporting very complex hypotheses about the modifications of the religious building during the centuries; theories which up to now didn't have enough support from the available historical documentation.

description: Our aim was to determine whether individual differences in feeding and social behavior in different social environments affect health outcomes in dairy cows. We used eight groups of four animals per treatment assigned to either a ‘predictable’ or an ‘unpredictable’ and competitive social environment. Predictable cows were given free access to six feed bins with no change in feed delivery times; whereas, the unpredictable cows were required to share one feed bin with one resident cow and morning feed was delayed 0, 1, 2, or 3 h every other day. On alternate days, the unpredictable cows were also re-assigned to a new bin and a new resident partner. Low daily dry matter intake (DMI) was a risk factor for cytological endometritis in predictable cows (odds ratio (OR) (95% confidence interval): 0.17 (0.02, 0.53)), but low daily DMI was protective for unpredictable cows (OR: 1.93 (1.09, 4.14)). Although low rate of DMI (kg/min) was a risk factor for cytological endometritis for predictable cows (OR: 4.2 × 10⁻¹⁰¹ (8.6 × 10⁻²⁰⁶, 4.8 × 10⁻³⁰)) it was unrelated to disease for unpredictable cows. There were no associations between feed bin visits or percentage of non-nutritive visits with the likelihood of cytological endometritis. This is the first evidence that individual differences in feeding behavior influence cytological endometritis risk in dairy cows, but the direction and magnitude of these effects is dependent on the social environment.
The effect of VKORC1 (-1639 G>A) gene polymorphism and its related clotting factor IIa and Xa on warfarin therapy in patients with atrial fibrillation: a multi-ethnic Sarawak population study
Creators: name: Lim, Melissa Siaw Han
Publisher: name: Swinburne
Year: 2024

description: Warfarin, the most frequently prescribed oral anticoagulant therapy management is challenging due to its narrow therapeutic index. It is associated with an increased risk of bleeding when overdose, while an insufficient dose may lead to thromboembolism or stroke. Due to the wide variation of response among patients, frequent monitoring of the efficacy of this drug through INR is essential. Recently emerged Novel Oral Anticoagulants (NOACs) have demonstrated to be non-inferior to warfarin therapy while abolishing the need for frequent blood INR testing. However, these are not commonly prescribed due to their current commercial pricing strategy with relatively limited indications compared to warfarin therapy, scenarios typically encountered in developing countries. Hence, there is a need to delineate a predictive model to determine the appropriate use of anticoagulant therapies in our country. This study aims to investigate the influences of coagulation factors (thrombin and Factor Xa) on poor TTR control patients while taking into account the impact of previously identified VKORC1 (-1639G>A) gene polymorphism. The VKORC1 AA genotype predominates in the multi-ethnic Sarawak population at a 71.5% majority. There was a significant difference in average daily warfarin dose (ADWD) between ethnic groups. Plasma thrombin levels were found to be significantly correlated with the TTR, ADWD, and BMI and were also found to be significantly higher in female patients but not plasma FXa levels. Majority of the patients with poor TTR<60% were on alternate dosing regimen with subtherapeutic INR readings. Multivariate analysis showed that alternate dosing regimen and plasma thrombin levels were independently associated with TTR while the VKORC1 (-1639G>A) gene polymorphism, diabetes mellitus, age and BMI are independent predictors or ADWD. Hence, it is demonstrated that the VKORC1 (-1639G>A) gene polymorphism together with other atrial fibrillation risk factors may be a strong predictive variable for ADWD, while the plasma thrombin levels may be a potential candidate marker in reflecting the quality of anticoagulation control based on TTR. Together, both models may be adopted to delineate a new strategy to determine who may potentially benefit from switching warfarin to the new NOACs.

description: The Veneto immigration, in the south of Brazil, produced geographically
closed communities, which for many years did not have any real contact with Brazilian groups, allowing an amalgamation process of the local cultures and of the dialect particularity, strengthening an ethnic and cultural idea.
Progressively, contact with other ethnic communities and the modernization process of the society conduced to a continuous loss of ancestral relationships founded in the solidarity and sociability bonds. In this sense, the filò, part of the habits that the immigrates carried with themselves, became a remembrance place of the departure land experiences and a place to reprocess the community memory. The rebuilt of the cultural code of this groups that came from the north of the peninsula produced the construction of an imaginary Veneto, that acquires his meaning from the immigration memory places.

L'immigrazione veneta, nel Brasile meridionale, produsse comunità
geograficamente chiuse, per diversi anni senza un contatto effettivo con i
gruppi brasiliani, permettendo un processo di amalgamazione delle differenti culture locali e dei particolarismi dialettali, rafforzando un'idea etnico-culturale.
Progressivamente, il contatto con le altre comunità etniche e il processo stesso di modernizzazione sociale portò a una perdita continua di antichi rapporti di solidarietà e sociabilità. In questo senso, il filò, usanza che gli immigrati portarono con sé dal Veneto, si costituì uno spazio del ricordo della terra di partenza e di elaborazione di una memoria comunitaria. Le rielaborazioni di codici culturali di queste popolazioni provenienti dal nord della penisola ha prodotto la costruzione di un Veneto immaginario, che acquisisce il suo significato dai luoghi di memoria dell’immigrazione.

Subjects: subject: Engineering, Electronics and Electrical.

description: Mobile communication on the Internet sets more security concerns than traditional mobile networks such as GSM. The network infrastructure registration process should give credentials to the user to let him or her being identified by any service provider in order to prevent fraudulent use. In addition, a user should be able to communicate with privacy and to sign a message (e.g. a payment order) so that billing is possible. Users should be able to connect from everywhere, with various types of terminals, possibly mobile. In this thesis, we propose to secure an infrastructure providing telecommunication services on the Internet for mobile users. We establish a trust relationship between any pair of the parties with a password-based user access. As for user-to-user communication, both signaling and media data can be secured. We illustrate the use of this infrastructure to provide secure IP-Telephony.

description: How much important and fundamental instruments, formation and information methods, different from the traditional ones in the different fields of human and experimental sciences, are today and will be in the future, is highlightened in this article. According to this, some problems typical of our instructive institutions (such as universities, public administrations, factories) and their relevant possible solutions are underlined. These solutions can be achieved thanks to the introduction of the "e-learning" i.e. the possibility of learning through the web. It is important to note that the usage of data processing systems and telecom technologies could improve the access to the learning resources and to meet the different requirements. A case that can be considered emblematic, with reference to our specific experience, is represented by the cultural heritage field and by the university teledidactic and telecom courses as "Cultural heritage Operator".

Kinetic and mechanistic solution studies are analyzed using 1H, 23Na and 39K NMR in order to compare the binding modes of the guests Na+ and K+. Both the sodium and potassium complexes exhibit a quantitative complexation (Kf > 10 4 M-1) in the temperature range of 238 to 320 K. The exchange between the complexed and solvated sodium cations is very slow on the 23Na NMR time scale at 320 K. Similarly, results for the exchange between the complexed and solvated potassium cations at 320 K were found to be slow to moderately slow on the 39K NMR time scale. Dynamics of the ethyl moiety are probed using 1H NMR and EXSY techniques. Analysis of 2-D EXSY 1H NMR data for the interconversion of the methylene protons from the N(CH2CH3)2 moiety of the (Na,1)+ and (K;1) + complexes exhibit slow exchange at 320 K.

description: Cr(VI) is identified as highly toxic, therefore a far-reaching limitation of total chromium or Cr(VI) in drinking water was proposed by the Germany Environment Agency. There is a lack in efficient treatment processes to reach Cr(VI) concentrations below 1 (my)g L-1. In this study, the combination of chemical reduction, coagulation and filtration (RCF) was further developed by adding biological iron removal as filtration step (RCbF). The aim of this enhancement was to reach lower effluent concentrations and a higher robustness regarding process parameters. The effectiveness of Cr(VI) removal was investigated using two-stage pilot-scale waterworks. RCbF reaches Cr(VI) effluent concentrations below 0.5 (my)g L-1 despite variations of pH, filtration velocity, or Cr(VI) influent concentrations. Fe(II) dosage and hence molar excess of Fe(II) over Cr(VI) was identified as the key parameter for Cr(VI) removal. Low oxygen dosage for biological iron removal improved the efficiency of RCbF compared to RCF. The co-precipitation of Cr(III) and Fe(III) as solid solution in the supernatant of the filter bed was promoted by low oxygen concentrations making Cr(VI) the preferred oxidant. RCbF was shown to be a suitable treatment process for reaching a low limit value for total chromium or Cr(VI) concerning technical feasibility. © 2020 The Authors.

description: Certain hydrogel forming de novo proteins that utilize different crosslinking methods are studied experimentally on a rheometer. The stress reaxation modulus of CRC, a telechelic, triblock protein, is shown to be that of a stretched exponential function with a value of β ≅ 0.5. The insertion of an integrin binding domain and changes in pH within the range 6.5–8.5 are shown not to significantly affect the resulting rheological behavior. A selective chemical crosslinker is used on CRC hydrogel systems and is shown to change the rheological behavior of the system to that of a combination of a chemically and physically crosslinked system. Chemically crosslinked hydrogels composed of W6, a wheat gluten-based protein, demonstrate a storage modulus weakly dependent on the angular frequency that is much greater than the loss modulus, with a modulus concentration dependence of c^9/4.

description: The precise details of the interaction of intense X-ray pulses with matter are a topic of intense interest to researchers attempting to interpret the results of femtosecond X-ray free electron laser (XFEL) experiments. An increasing number of experimental observations have shown that although nuclear motion can be negligible, given a short enough incident pulse duration, electronic motion cannot be ignored. The current and widely accepted models assume that although electrons undergo dynamics driven by interaction with the pulse, their motion could largely be considered ’random’. This would then allow the supposedly incoherent contribution from the electronic motion to be treated as a continuous background signal and thus ignored. The original aim of our experiment was to precisely measure the change in intensity of individual Bragg peaks, due to X-ray induced electronic damage in a model system, crystalline C 60 . Contrary to this expectation, we observed that at the highest X-ray intensities, the electron dynamics in C 60 were in fact highly correlated, and over sufficiently long distances that the positions of the Bragg reflections are significantly altered. This paper describes in detail the methods and protocols used for these experiments, which were conducted both at the Linac Coherent Light Source (LCLS) and the Australian Synchrotron (AS) as well as the crystallographic approaches used to analyse the data.

description: The good-will to operate in the old town privileging the history and the maintenance of historic buildings, is manifest in this study on the Vittorio Emanuele monumental street, the foundation axis of Palermo, and it’s architectural degraded and disfigured fronts.
The search concerning sixty civil buildings is based initially on a cognitive process that includes historical analysis, geometric and dimensional survey, investigation on constituent materials and decay systems, in relation to environmental or anthropic causes.
The study includes a design proposal that, according to the individuality of cases, it would represent an intervention code about some recurrent critical aspects on which it’s possible to intervene only applying codified procedures. The proposed designs show so an application to concrete cases, not
abdicating to involve physical and economic urban environment: the re-qualification of building materials and architectural language would respect the historical image without depressing the market demands.

description: Cette recherche aborde la contribution du leadership à la construction de l’intelligence collective dans une équipe de travail qui produit un bulletin de nouvelles télévisé. L’intelligence collective est une façon de travailler qu’ont développée les organisations hautement fiables, c’est-à-dire les organisations où la moindre erreur peut mener à la catastrophe. En favorisant la capacité de s’adapter à un environnement en constante évolution, le développement de l’intelligence collective permet aux organisations d’être plus compétitives dans un univers imprévisible. Nous avons tenté de voir si les mécanismes de construction de l’intelligence collective étaient présents dans une salle des nouvelles et comment le leadership émergent contribuait à la construction de ces mécanismes. Nous avons mobilisé les théories du sensemaking et de l’organizing de Weick et avons étudié les interactions entre les acteurs de l’organisation en contexte. L’analyse a montré comment un leadership distribué parmi les membres a contribué à l’émergence des mécanismes de l’intelligence collective. L’originalité de ce travail repose sur la mise en relation de l’observation du leadership en émergence et de la construction de l’intelligence collective. En ce sens, nous croyons qu’il peut contribuer aux recherches sur l’intelligence collective en présentant concrètement comment elle se construit dans une équipe de travail.

description: Human norovirus (NoV) causes gastroenteritis worldwide and has been associated with a number of produce related outbreaks. The design of effective inactivation and prevention procedures requires an understanding of virus survival in environments applicable to the production and processing of fresh produce. To evaluate the extent of NoV risk from farm to fork, the survival of murine norovirus (MNV), a surrogate for human NoV, was studied on stainless steel disks, soil and in bottled water for 42 days and on lettuce for 15 days in the laboratory. Stability experiments were then conducted on farm during one lettuce planting/harvest cycle, for 4 weeks. MNV stability was tested at room temperature in the laboratory or under ambient conditions on the farm. A one log reduction in virus titre was achieved after 30 days in water, 4 days on lettuce, 15 days on stainless steel disks, 12 days on loamy and sandy soil. For farm testing, infectious virus was recovered from both soil and lettuce on the day of inoculation. Although infectious virus was not recovered at later time points, the viral genomes were detected for up to four weeks. The observed long-term persistence of NoV, under both laboratory and field conditions, provides valuable information for developing risk assessments and control procedures to limit the possibility for NoV transmission in the food supply.

description: Background A coordinated stroke rehabilitation care team is considered optimal for supporting stroke survivors from diagnosis to recovery. Despite this recognition, many stroke survivors cannot access essential rehabilitation services. Furthermore, there is a lack of understanding of stroke patients’ and their caregivers’ rehabilitation needs and wishes. We sought to gain insight into healthcare and social structures from the perspective of patients and caregivers that can better support long-term stroke recovery. Methods We conducted individual interviews with 24 participants comprised of stroke survivors, spousal caregivers, stroke support group coordinators, and speech pathologist. Participants were recruited through three stroke survivor support groups. An empowerment lens was integrated into data analysis and data interpretation. Results Two dominant themes captured participants’ experiences through stroke survivors’ trajectory of care. 1) Experiences of managing stroke. This theme identified stroke survivors and spousal caregivers’ experiences with stroke recovery, rehabilitation, and fulfilling unmet needs. 2) Resources of support. This theme described the social and financial support structures drawn upon to assist with stroke rehabilitation. Conclusions The study highlighted a lack of teamwork between stroke survivors, spousal caregivers, and health professionals. This fragmented care was compounded by inequities in rehabilitation programs and health services resulting in what appeared to be a disempowering rehabilitation process. Although stroke recovery groups were a significant source of support for stroke survivors and spousal caregivers, participants perceived they were overlooked, by stroke recovery healthcare providers, as a site for stroke recovery healthcare services. An empowerment approach to stroke rehabilitation involves collaboration between stroke survivors, caregivers, healthcare providers, health services, and existing community stroke support structures. Framing stroke based care through an empowerment lens may serve to address stroke rehabilitation inadequacies and inequities.

description: Recent, significant advances in measurement technology and algorithm developments have made products  from ground-based remote sensing profile observations increasingly interesting for stakeholders. Provided standardised operations, careful processing and adequate quality control (according to guidelines formulated by WG 3 and WG 4 of PROBE), these profiling products contain unprecedented spatial (horizontal and vertical) and temporal detail of variables characterising the Atmospheric Boundary Layer (ABL). Sensor networks and retrievals are typically optimised for specific, individual applications, however as shown by WG2 of PROBE, synergistic procedures combining  complementary sensors help to maximise exploitation of these rich data for a number of different purposes. While network observations from ground-based profilers are being recognised as valuable data sources by different communities, the measurements are still far from being exploited at their full potential. 

Here, we highlight first applications of ground-based remote sensing ABL observations in emerging network structures. Our selection of applications is by no means providing a full picture of all impacts that ABL observations may have but rather showcases a number of representative examples. While some are established applications that are already integrated in operational procedures, others are still more experimental or even present a prospect for future developments.

The showcases will be of interest to a wide range of stakeholders, including academic research in many fields as well as national meteorological and hydrological services, environmental agencies, space agencies, renewable energy suppliers, urban planners and the safety and transportation sector among others.
