This study examined the effect of a 10-week activity tracker, companion social website, and text messaging intervention on body mass index (BMI), body fat percentage, physical fitness, and physical activity (PA) self-efficacy of children. Children ( n = 98) were assigned to one of three groups: activity tracker group, text messaging group, and activity tracker + text messaging group. Pre-/posttest fitness, BMI, PA self-efficacy, and body fat percentage were measured. The activity tracker group had a significant increase in fitness, no significant difference in PA self-efficacy, and an increase in body fat percentage and BMI ( p < .05). The text messaging group had a significant increase in BMI ( p < .05). The activity tracker + text messaging group had no significant differences in fitness, BMI, PA self-efficacy, or body fat percentage. This study gives no clear support to the hypothesis that use of activity trackers and a text messaging intervention have a positive effect on fitness, PA self-efficacy, or body fat percentage.

Wearable activity trackers have gained popularity among individuals who want to track their physical activity (PA). The features of wearable tracking technology that are known to facilitate positive behavior changes such as self-monitoring and social connectedness) are well documented; yet, the existing evidence is not conclusive in the literature requiring further investigation. This study was an 8-week pilot randomized controlled study examining the effectiveness of PA intervention incorporating a wearable activity tracker’s online connectivity feature. Forty participants were equally randomized into either an individual-based (n = 20) or a connected group (n = 20). A Jawbone UP24 tracker was provided to all participants in both groups as a means of self-monitoring PA for eight weeks, but the connected group was additionally instructed to share their PA levels with the others using the accompanying smartphone application. Participants’ weekly step counts were evaluated each week to examine the change in PA. Participants’ biometric variables such as body weight, body mass index, waist circumference, blood pressure, and psychological status, including self-efficacy (SE) and exercise motivation (EM), were measured from both groups before and after the intervention period. Additionally, the social support questionnaire (SSQ) was measured among the connected group. The statistical significance level was set at <0.05. The average step counts for eight weeks were significantly increased only in the connected group (p < 0.001). Significant differences in step count improved from the baseline to week 8 in the connected user group (p < 0.01), but only baseline vs. week 7 in the individual users. Also, no significant interaction effects for biometric variables, EM, and SE were founded. However, SSQ was significantly improved in the connected user group (p < 0.001). PA intervention combining a wearable activity tracker and online social connectivity feature shows a greater effectiveness of promoting PA than a wearable tracker alone

Objective Wearable activity trackers can help older adults remain physically active. However, knowledge of the user experience during long-term use is scarce. Therefore, this study examined older adults’ experiences with, and perceptions of, wearable activity trackers combined with health professional feedback after a year’s use as part of a randomised controlled trial. Methods Twenty older adults (73.6 ± 5.5 years) who had used a Jawbone UP24 activity tracker for 12 months during a randomised controlled trial were recruited for this study. All participants had at least one chronic condition. Acceptability data relating to activity tracker wear time was combined with focus group data to explore participants experiences of long-term activity tracker use. Data was analysed using thematic analysis. Results The activity tracker was well-accepted with the device worn on an average of 86% of possible days and participants reported an overall positive experience. Four themes were identified: (a) increased sense of awareness of activity levels is related to motivation; (b) the level of engagement with the activity tracker influences the user experience; (c) the role of feedback from a health professional in providing ongoing support; d) the role of habits in supporting long-term behaviour change. Conclusions The use of an activity tracker combined with health professional support can assist older adults to maintain their activity levels over 12 months. Consideration should be given to the previous technology experience of users and the design and accuracy of an activity tracker when recommending their use in a research or clinical setting.

Abstract Daily walking activities are associated with improving cardiovascular and well-being in older kidney transplant recipients. Multicomponent interventions using technology and goal setting holds promise for sustaining daily walking activity among this population. The purpose of this randomized controlled trial pilot study was to evaluate the feasibility of a multicomponent intervention called SystemCHANGE™ + activity tracker for daily walking activity in older (age 60 and over) kidney recipients from baseline to 12 months. The intervention group implement a personal-system solution and wore a mobile activity tracker daily for 12 months. The attention-control group received educational information on healthy living as a transplant recipient and was asked to wear a mobile activity tracker daily for 12 months. Participants were randomized 1:1 to the intervention or control group. The sample consisted of 53 participants (n = 27 intervention, and n = 26 control). At the 12-month follow-up visit, the total study attrition rate was 23%. The adherence rates at 12 months were 96.5% in the intervention group and 80.8% in the attention- control group. The intervention group increased their steps from baseline to 12 months by 334 steps per day. The attention-control group demonstrated a decrease in steps by 563 steps per day. We found a mean difference of 1041± 2440 (Cohen’s d = 0.43) in daily steps between the groups from baseline to 12 months. The data suggests SystemCHANGE™ in combination with activity trackers may be feasible for older kidney transplant recipients to enhance and sustain physical activity with daily walking.

Background Physical activity is a critical component of health. Objective We implemented a pilot project to determine feasibility of embedding activity tracker data within routine primary care visits among family medicine residency patients. This study also examined whether physician monitoring of and feedback concerning tracker improves exercise compliance and overall health. Methods Twenty-six participants received the FitBit Charge HR and were randomized into the self-monitoring (control) or intervention group for 12 weeks. The intervention group received weekly electronic health record (EHR) messages from their physician with feedback. The control group self-monitored activity. Results Data demonstrates patient interest in sharing exercise data with primary providers, patient-generated exercise data can be embedded within visits to personalize recommendations, and patient-physician data sharing is logistically feasible via the EHR. Conclusion Physicians can utilize activity trackers to potentially positively influence patients’ exercise. This research supports the shift toward personalized medicine by facilitating conversations and additional studies about fitness data.

Context. The GRAVITY instrument was commissioned on the VLTI in 2016 and is now available to the astronomical community. It is the first optical interferometer capable of observing sources as faint as magnitude 19 in K band. This is possible through the fringe tracker, which compensates the differential piston based on measurements of a brighter off-axis astronomical reference source. Aims. The goal of this paper is to describe the main developments made in the context of the GRAVITY fringe tracker. This could serve as basis for future fringe-tracking systems. Methods. The paper therefore covers all aspects of the fringe tracker, from hardware to control software and on-sky observations. Special emphasis is placed on the interaction between the group-delay controller and the phase-delay controller. The group-delay control loop is a simple but robust integrator. The phase-delay controller is a state-space control loop based on an auto-regressive representation of the atmospheric and vibrational perturbations. A Kalman filter provides the best possible determination of the state of the system. Results. The fringe tracker shows good tracking performance on sources with coherent K magnitudes of 11 on the Unit Telescopes (UTs) and 9.5 on the Auxiliary Telescopes (ATs). It can track fringes with a signal-to-noise ratio of 1.5 per detector integration time, limited by photon and background noises. During good seeing conditions, the optical path delay residuals on the ATs can be as low as 75 nm root mean square. The performance is limited to around 250 nm on the UTs because of structural vibrations.

The clustering algorithm is a method of distributing the population or data points into different groups in a way that data points in a single group are alike to each other in the same group and different from the data points from another groups. Simply, the objective is to isolate groups with similar qualities and allocate them into groups. This research, focus on K-means algorithm. Therefore, type of clustering algorithm used to cluster a group of data without categories. As, the clustering is a subjective phenomenon, that can be employed for accomplishing this objective to find and create group in the data with K as the representation of the number of the groups. Thus, the algorithm procedure uses a dissimilar set of guidelines for describing the relationship between data points and will be clustered together. Indeed, there are over 100 clustering algorithms recognized. However, a crime investigation tracker using clustering algorithm uses K-means algorithm to group the identical crime to be clustered accordingly type of crime recorded in the system. For the system, will be developed using Java programming to build the interface with MySQL as the database to provide a better management to store and retrieve the report. A methodology to develop the system is using Agile Unified Process (AUP) is consists of inception, elaboration, construction, and transition to conducts the current problem of system that various crimes have been increasing, unorganized reports in storage and interface less user friendly of the current system.

Annotation:

Deep features extracted from convolutional neural networks have been recently utilized in visual tracking to obtain a generic and semantic representation of target candidates. In this paper, we propose a robust structured tracker using local deep features (STLDF). This tracker exploits the deep features of local patches inside target candidates and sparsely represents them by a set of templates in the particle filter framework. The proposed STLDF utilizes a new optimization model, which employs a group-sparsity regularization term to adopt local and spatial information of the target candidates and attain the spatial layout structure among them. To solve the optimization model, we propose an efficient and fast numerical algorithm that consists of two subproblems with the close-form solutions. Different evaluations in terms of success and precision on the benchmarks of challenging image sequences (e.g., OTB50 and OTB100) demonstrate the superior performance of the STLDF against several state-of-the-art trackers.

Sarcoidosis causes many disabling symptoms, including fatigue and exercise limitations, which have been shown to improve by physical activity programs. The aim of this study was to estimate the effect of continuous activity monitoring using an electronic activity tracker (AT) on exercise performance and fatigue of sarcoidosis patients, compared to controls (cohort study), and the effect of additional personal coaching (randomized trial) over a period of 3 months. Fifty-four sarcoidosis patients received an AT (Group Ia: 27 with coaching and Group Ib: 27 without). A historical group of sarcoidosis patients (Group II; n = 41) who did not follow a physical activity program served as controls. Exercise performance of patients wearing an AT (Group I) improved compared with controls (Group II), including the 6MWD, % predicted (∆4.4 ± 9.1 versus ∆0.7 ± 5.0, respectively), and fatigue levels decreased (∆−3.9 ± 5.7 versus ∆−1.8 ± 5.3). Patients with coaching (Group Ia) showed greater improvement of exercise capacity over time than patients without coaching (Group Ib) as shown by the Steep Ramp Test results (watts: ∆20.2 ± 33.8 versus ∆5.7 ± 26.4; and SRT, VO2max, % predicted: ∆1.6 ± 2.6 versus ∆0.7 ± 2.3). Sarcoidosis patients wearing an AT achieved improvement of exercise performance and reduction of fatigue. We therefore recommend encouraging sarcoidosis patients to wear an AT to stimulate physical activity and reduce fatigue. The additional benefit of coaching needs to be explored in future studies.

The paper details the usage of mmWave radars to track people and monitor their movement through predefined zones of interest. The theoretical part describes the physical nature of the technology and then describes algorithms which can be used to monitor using it to monitor the movement of people. In the practical part, I have developed a concrete algorithm which can be used to monitor customer queues and cash registers in shops and inform the cashiers when their presence is needed, as well as gather impersonal GDPR-compliant data about the customer's habits. Afterwards, I have developed a visualization for the Windows platform, which can be used to communicate with the radar, manage its configuration, visualize the events in real time and perform further analysis of the measured data.

So often in astronomy, an object is not considered for its individual merits, but for what we may learn from its properties regarding some larger population. The existence of dark matter is a prime example of this; we cannot see it directly but we can infer its presence by noting its effects on the stars orbiting within its potential. This thesis describes how various sets of tracer populations can be used to probe the properties of a variety of galaxies in the Local Group. I begin by describing the extraction of a variable catalogue from the Sloan Digital Sky Survey Stripe 82 dataset and then use the catalogue to select a high-quality set of RR Lyrae stars. Analysing the distribution of the RR Lyraes reveals three significant substructures in the Milky Way halo: the Hercules-Aquila Cloud and the Sagittarius Stream, which were already known to exist, and the Pisces Overdensity, which was previously undetected. It is a faint, extended structure found at ~80 kpc and is of unknown origin. Altogether, I find that nearly 80% of the RR Lyraes are associated with substructures, consistent with the theory that galaxy halos are predominantly, or even entirely, made up from disrupted satellites. I also investigate the density distribution of RR Lyraes in the halo, finding that it is best fit by a broken-power-law model, in good agreement with previous work. I go on to develop a set of tracer mass estimators that build on previous work which make use of actual (and not projected) distance and proper motion data, reflecting the amount and quality of data now available to us. I show that proper motion data is, in theory, very useful and can greatly increase the accuracy of the mass estimates; in practice, however, current analysis is hampered by the large errors inherent in the proper motion data. The results are also subject to mass-anisotropy degeneracy, which current data is not yet able to break. Nevertheless, I am able to estimate the mass of the Milky Way to be M = 2.7 ± 0.5 x 10¹² Msun and the mass of M31 to be M = 1.5 ± 0.4 x 10¹² Msun. Andromeda XII and Andromeda XIV are two M31 satellites that have been dubbed 'extreme' and are thought to be on first infall into the M31 system. I modify the classical Timing Argument so that it can be applied to two external galaxies and then apply it to M31 and each of And XII and And XIV in turn to investigate the properties of their orbits. I then run a series of Monte Carlo simulations to investigate how likely such satellites are to exist and conclude that they are not as unusual as previously believed. Finally, I discuss three upcoming wide-field, all-sky surveys and their implications for the future of the study of the Local Group.

Annotation:

La spécificité de l’adolescence est la venue au premier plan de la génitalité. Cela entraîne à la fois une métamorphose du corps et un remaniement psychique. À l’adolescence, le corps est aussi un lieu de contradiction que tantôt il attaque, tantôt il embellit dans un érotisme effréné. En effet, la contradiction peut se traduire sous forme symptomatique et manifester l’encombrement que l’adolescent ressent devant son corps qui lui échappe. Il ne sait pas repérer ce qu’il ressent, il ne sait pas le nommer et même il ne sait pas qu’il ne sait pas. Parfois le rapport qu’il entretient avec son corps est suffisamment paradoxal pour qu’il ne puisse pas se l’approprier. C’est cette étrangeté qui va provoquer un clivage chez l’adolescent. Les deux perspectives qui émanent de ces positions sont assez différentes quant à l’avenir du sujet. Ce travail s’inscrit dans la continuité de divers travaux de recherche sur la problématique adolescente. Il vient rendre compte de la mise en place dans un service de Pédiatrie générale d’un groupe thérapeutique à médiation écriture avec des adolescentes qui se scarifient. C’est en considérant ces scarifications comme un langage du corps au coeur de la problématique adolescente et pubertaire, et au regard des difficultés que ces adolescentes ont à mettre des mots sur l’indicible de leur douleur, que le groupe a été créé. La mise en place de celui-ci correspond plus globalement à une réflexion sur le processus d’adolescence, de subjectivation, et le rapport au corps, notamment à travers le travail de symbolisation à l’adolescence. Nous interrogeons également à l’endroit de notre réflexion, la médiation écriture en tant que dépôt d’une trace sur un support, qui au même titre que la rencontre de la lame sur la peau, viendrait comme une butée (Le Breton, 2002) ; la rencontre avec la feuille par analogie au corps viendrait recréer et offrir un contenant à la souffrance psychique. Le groupe quant à lui pourrait être vécu comme espace transitionnel au sens où l'entend Winnicott, au fondement de l’expérience créatrice et rassurante pour l’adolescente. Le corps aurait alors une fonction semblable dans ce qu'il incarnerait une frontière entre un dedans et un dehors. Une des fonctions de la pratique scarificatoire serait alors de restaurer les limites du Soi dans une lutte contre un possible effondrement The specificity of adolescence is the coming to the fore of genitality. This involves both a metamorphosis of the body and a psychic reworking. The body is also a place of contradiction that sometimes attacks, sometimes it embellishes in a frenzied eroticism. Indeed, the contradiction can be translated in symptomatic form and manifest the clutter that the adolescent feels in front of his body that escapes him. He does not know how to identify what he feels, he does not know how to name it and he does not even know he does not know. Sometimes the relationship he has with his body is sufficiently paradoxical that he can't appropriate it. It is this strangeness that will cause a cleavage in the adolescent. The two perspectives that emanate from these positions are quite different as to the future of the subject. This work is a continuation of various research works on the adolescent problem. He reports on the establishment of a therapeutic group in writing in a Pediatric General Service, writing with teenagers who are scarifying themselves. It is by considering these scarifications as a body language at the heart of the adolescent and pubertal problem, and in view of the difficulties that these teenagers have to put words on the indescribable of their pain, that the group was created. The setting up of this one corresponds more generally to a reflection on the process of adolescence, of subjectivation, and the relation with the body, in particular through the work of symbolization in adolescence. We also question the place of our reflection, the mediation writing as a deposit of a trace on a support, which as well as the meeting of the blade on the skin, would come as a stop (Le Breton, 2002); the encounter with the sheet by analogy with the body would come to recreate and offer a container for psychic suffering. The group could be seen as a transitional space in Winnicott's sense, at the root of the creative and reassuring experience for the teenager. The body would then have a similar function in what it would incarnate a border between an inside and an outside. One of the functions of the scarificatory practice would then be to restore the limits of the Self in a fight against a possible collapse

Ability grouping has become increasingly common in the teaching of English in Swedish secondary schools. This study was concerned with the effects of different group constellations on the more able pupils. The research questions involved the able pupils’ performance, their roles in mixed-ability groups and whether the learning environment is better for them when they work with other able pupils. The study used discourse analysis of group interaction in the target language between pupils in year eight. It was found that able pupils perform according to their pre-defined skill, regardless of what groups they were put in. They also supported and lifted the interaction to higher levels in mixed-ability groups. Finally, the results suggested that able pupils might have a greater chance to develop their English in tracked groups. It is argued that this has implications for the implementation of ability grouping in the teaching of second languages in Sweden.

In this thesis we present two important closely related examples of Bratteli diagrams: the Pascal triangle and the Eulerian Bratteli diagram. The former is well-known and related to binomial coefficients. The latter, which is the main object of the thesis, is related to the Eulerian numbers. Bratteli diagrams were introduced in 1972 by Ola Bratteli in his study of approximately finite dimensional (AF) C*-algebras. In 1976, George Arthur Elliott associated to an AF C*-algebra or to a corresponding Bratteli diagram an ordered group, he called dimension group. In the first part of the thesis we study the space of infinite paths of the Eulerian diagram, and we realize it as a projective limit of finite permutation groups. In the second part, we study the state space of the dimension group associated to the Eulerian Bratteli diagram. It is a compact convex set and we describe its extremal points. Finally, we use this description to give a necessary and sufficient condition for an element of this dimension group to be positive.

Entre 1952 et 1956, l'Independent Group (IG) a réuni à L'Institute of Contemporary Arts (ICA) de Londres, des figures majeures de l'architecture, parmi lesquelles Alison et Peter Smithson et Colin St John Wilson, de l'art, celles de Richard Hamilton, Eduardo Paolozzi, Nigel Henderson et William Turnbull, de l'histoire et de la critique de l'art et de l'architecture, celles de Reyner Banham et Lawrence Alloway. La composition changeante et controversée du groupe, aussi bien que l'absence d'une publication, d'un manifeste fondateur ou d'un programme commun, ont imposé d'éclaircir en quelle mesure l'IG a été véritablement un groupe et quelle importance a eu le choix du nom "Indépendant". Le titre "Du pastiche à l'original" indique une méthode d'analyse par laquelle l'histoire du groupe est examinée à rebours, en partant des traces historiques. Entre 2002 et 2005, des entretiens et des correspondances ont permis de préciser le sens donné par certains ex-membres du groupe aux notions opératoires du pop art : le collage, le pastiche, l'original multiple, la répétition, etc. . . à travers lesquelles, paradoxalement, a été amenée la problématique de l'original au centre de la recherche Between 1952 and 1956, the Independent Group gathered at the Institute of Contemporary Arts (ICA), London, the leading figures of architecture such as Alison and Peter Smithson, Colin St John Wilson, of art, such as Richard Hamilton, Eduardo Paolozzi, William Turnbull, Nigel Henderson, or of history and criticism of art and architecture, such as Reyner Banham, Lawrence Alloway. The shifting and uncertain composition of the group and the absence of any joint publication, manifesto or programme, brings up the question of the IG as a genuine group, as well as the importance of the choice of the name Independent. The title From pastiche to Masterpiece indicates a method where the history of the group is examined through flash-backs, constructed from the available historical traces. Between 2002 and 2005, interviews and correspondence helped to clarify the meaning given by certain ex-members of the IG to the key notions of Pop art, such as collage, pastiche, "multiples", repetition, that made the question of the Original central to the research

Due to the low amount or unfavorable annual distribution of precipitation the exploration, allocation, sustainable exploitation, and protection of replenishable as well as fossile water resources are challanging tasks in semiarid and arid regions. Beside a few natural or artifcial surface water reservoirs the porous underground at the same time is the largest storage and transport medium for water and provides protection against evaporation and to a certain degree against surcficial introduction of contaminants. This situation is characteristic for the Near East and thus for the selected investigation areas, that are located in Israel and the West Bank, and that are subject of the conducted partail studies that are presented. The work focuses on three main subjects. On the one hand, it deals with the characterization of the young groundwater components of the discharge of four major springs of Wadi Qilt and Jericho, as well as of sampled deep wells of three important well fields. All of these objects discharge or abstract water from the Upper and Lower Judea Group Aquifer. With a thickness of about 750 m it is one of the most important groundwater reservoirs of the region and comprises mainly to varying degrees karstified and fractured limestones and dolomites. These formations underwent uplift during Senonian to Eocenian times forming a pair of double-plunging anticlinal structures (Hebron and Ramallah or Judea and Samaria Mountains, respectively) that are again subdivided into minor anticlines and synclines. The groundwater replenishment is restricted to the winter season between October and April, and to the crestal area of the mountains, where the otherwise covered aquifer rocks crop out. A strategy was developed to interpret the applied tracers for all locations in a similar way using a lumped parameter approach, which enables a direct comparison. On the other hand, the work investigates salinization processes in the Shallow Aquifer of Jericho and their discrimination. Potential sources for salinization are remnant brines that are activated to flow into the range of well extraction due to groundwater overexploitation, dissolution of salts, or formation waters from the Lisan formation. These layers represent the sediments of Lake Lisan, the Pleistocene precursor of the Dead Sea. A discrimination of the salinization mechanisms is important to develope reasonable measures to limit or lower the salt concentration in the affected wells. Consequently, the relevant measured but also potential main hydrochemical indicators and isotope tracers are identified. The large uncertainties with respect to the establishment of a well-founded water balance and to the insuffcient knowledge about the geology of the small-scale area of Jericho are discussed. Because the interpretation of the measured helium samples from the fractured and karstified aquifer of the Cretaceous Judea Group is limited, the dependencies of the He-4 accumulation in groundwater in an idealized dual-continuum aquifer are investigated with respect to the relation of the He-4 mass fluxes and the system response time to the varied parameters (groundwater head gradient, hydraulic conductivities, dispersivities, porosities) by means of a sensitivity analysis. Although the system response time is not a system variable as such it clearly turned out that knowledge about it may be an important information for the interpretation of He concentrations in groundwaters of non-stationary systems. To enhance the visual post-processing of the parameter sensitivity analysis an easily interpretable way of data presentation is introduced Semiaride und aride Gebiete stellen aufgrund des niedrigen oder ungünstig verteilten Niederschlagsdargebots eine besondere Herausforderung bezüglich Erkundung, Bereitstellung, nachhaltiger Nutzung und Schutz sich neu bildender, aber auch fossiler Wasserresourcen dar. Abgesehen von wenigen natürlichen oder künstlich angelegten Oberflächenreservoiren ist der poröse Untergrund dabei gleichzeitig Hauptspeicher und Transportmedium für Wasser und bietet einen Schutz gegen Verdunstung und bis zu einem gewissen Grade gegen oberflächig einwirkende Verunreinigungen. Diese Situation ist charakteristisch für den Nahen Osten und damit für die im Rahmen der vorliegenden Arbeit beschriebenen Teiluntersuchungsgebiete, die sich in Israel und der West Bank befinden. Die Arbeit behandelt drei Hauptthemen. Einerseits geht sie auf die Charakterisierung der Jungwasseranteile im Abfluß vier bedeutender Quellen des Wadi Qilts und Jerichos sowie in beprobten tiefen Brunnen dreier wichtiger Brunnenfelder ein. Alle diese Objekte entwässern bzw. entnehmen Wasser aus dem Oberen oder Unteren Judea Group Aquifer. Mit ca. 750 m Mächtigkeit stellt dieser eines der bedeutensten Grundwasserreservoire der Region dar und besteht hauptsächlich aus unterschiedlich stark verkarsteten und gestörten Kalkstein- und Dolomitformationen, welche zwischen dem Senon und Eozän in Form einer in sich weiter gegliederten, beid-seitig abtauchenden Doppelantiklinalstruktur herausgehoben wurde (Hebron und Ramallah bzw. Judea und Samaria Mountains). Die Grundwasserneubildung ist beschränkt auf die Zeit zwischen Oktober und April sowie auf die Kammlagen des Gebirges, wo die sonst bedeckten Schichten des Aquifers ausstreichen. Es wurde eine Strategie entwickelt, die eingesetzten Tracer auf ähnliche Weise mit Hilfe von Lumped Parameter-Modellen für alle Lokationen zu interpretieren und somit eine Vergleichbarkeit zu gewährleisten. Andererseits untersucht die Arbeit Versalzungsprozesse im Shallow Aquifer von Jericho und deren Abgrenzung untereinander. Mögliche Hauptquellen der Versalzung sind durch überhöhte Grundwasserentnahme verstärke Zuflüsse von Solen, die Lösung von Salzen aus der Lisan-Formation oder Formationswässer der Lisan-Formation, welche die Ablagerungen des Lisan-Sees, des Pleistozänen Vorgängers des heutigen Toten Meeres, repräsentieren. Eine Unterscheidung der Mechanismen hat dabei durchaus Bedeutung für die Festlegung geeigneter Gegenmaßnahmen. Demzufolge werden die ermittelten, aber auch weitere, potentielle hydrochemische Hauptindikatoren und Tracer benannt. Unsicherheiten sowohl hinsichtlich der Aufstellung einer Wasserbilanz, als auch einer unzureichend bekannten Geologie für das sehr kleinräumige Gebiet von Jericho werden diskutiert

AbstractThe chapter summarizes the new results of the Bàsura Revisited Interdisciplinary Research Project. The integrated interpretation of recent archaeological data and palaeosurface laser scans, along with geoarchaeological, sedimentological, geochemical and archaeobotanical analyses, geometric morphometrics and digital photogrammetry, enabled us to reconstruct some activities that an Upper Palaeolithic human group led inside a deep cave in northern Italy within a single exploration event about 14 ka calBP. A complex and diverse track records of humans and other animals shed light on individual- and group-level behaviour, social relationship and mode of exploration of the uneven terrain. Five individuals, composed of two adults, an adolescent and two children, entered the cave barefoot lightening the way with a bunch of wooden sticks (Pinus t. sylvestris/mugo bundles). While proceeding, humans were forced to move on all fours, and the traces they left represent the first report of crawling locomotion in the global human ichnological record. Anatomical details recognizable in the crawling traces show that no clothing was present between limbs and the trampled sediments. Our study demonstrates that very young children (the youngest about 3 years old) were active members of the human groups, even in apparently dangerous and social activities, shedding light on behavioural habits of Upper Palaeolithic populations.

The need to divide attention in order to deal with information flowing in from a number of sources is observable in many work settings. Although most people can perform several simple activities concurrently, such as eating and watching television (Sharon, 1997), making simultaneous decisions is difficult (Pashler & Johnston, 1998). For the majority, task overload causes errors in performance (Girard, 2007), a decline in the quality of treatment (Ruthruff et al., 2001), and longer reaction time (Levy et al., 2006). The few who cope efficiently under such circumstances employ different cognitive strategies. Teamwork is one way of managing multiple demands. Group work makes it possible to deal with larger amounts of information and to generate a variety of ideas as well as to minimize faulty conclusions. On the other hand, individuals make speedier and better decisions, and are not subject to the tensions of interplay (Davis and Toseland, 1987). The literature offers little information on methods of testing the conditions under which tasks should be handled by one agent or a team. The educational project described here was conducted comparing efficiency of performance of a series of tasks by individuals and small groups. 116 participants, ranging in age from high school level through holders of Masters' degrees, 58 women and the same number of men, were presented with a computer game based on educational software. Participants were instructed to manipulate a tracker by means of the keyboard in order to contact a target moving randomly on the screen. The game was arranged in five levels of difficulty. A comparison was made of the speed in which objectives were attained when performed individually and when divided among groups of two to four partners, controlling for the type of coordination, cognitive style and additional background variables. Cases of expedient and inexpedient division of labor were identified, as were factors affecting feasibility. Among the latter were the size of the simultaneous task load, complexity level, number of participants, and the intensity of coordination required among them.

Designed for detecting train presence on tracks, track circuits must maintain a level of high availability for railway signaling systems. Due to the fail-safe nature of these critical devices, any failures will result in a declaration of occupancy in a section of track which restricts train movements. It is possible to automatically diagnose and, in some cases, predict the failures of track circuits by performing analytics on the track signals. In order to perform these analytics, we need to study the coded signals transmitted to and received from the track. However, these signals consist of heterogeneous pulses that are noisy for data analysis. Thus, we need techniques which will automatically group homogeneous pulses into similar groups. In this paper, we present data cleansing techniques which will cluster pulses based on digital analysis and machine learning. We report the results of our evaluation of clustering algorithms that improve the quality of analytic data. The data were captured under revenue service conditions operated by Alstom. For clustering algorithm, we used the k-means algorithm to cluster heterogeneous pulses. By tailoring the parameters for this algorithm, we can control the pulses of the cluster, allowing for further analysis of the track circuit signals in order to gain insight regarding its performance.

Because many patients reduce exercise following outpatient cardiac rehabilitation (CR), we developed an intervention to assist with the transition and evaluated its feasibility and preliminary efficacy using a one-group pretest–posttest design. Five CR patients were enrolled ~1 month prior to CR discharge and provided an activity tracker. Each week during CR they received a summary of their physical activity and steps. Following CR discharge, participants received an individualized report that included their physical activity and step history, information on specific features of the activity tracker, and encouraging messages from former CR patients for each of the next 6 weeks. Mixed model trajectory analyses were used to test the intervention effect separately for active minutes and steps modeling three study phases: pre-intervention (day activity tracking began to CR discharge), intervention (day following CR discharge to day when final report sent), and maintenance (day following the final report to ~1 month later). Activity tracking was successfully deployed and, with weekly reports following CR, may offset the usual decline in physical activity. When weekly reports ceased, a decline in steps/day occurred. A scaled-up intervention with a more rigorous study design with sufficient sample size can evaluate this approach further.

In response to the Paris Agreement and the Sustainable Development Goals (SDGs), the IDB Group Board of Governors endorsed the target of increasing climate-related financing in Latin America and the Caribbean (LAC) from 15% in 2015 to 30% of the IDB Groups combined total approvals by 2020. Currently, the IDB Group is on track to meet this commitment, as in 2018, it financed nearly US$5 billion in climate-change-related activities benefiting LAC, which accounted for 27% of total IDB Groups annual approvals. In 2019, the overall volume and proportion of climate finance in new IDBG approvals have increased to 29%. As the IDB continues to strive towards this goal by using its funds to ramp-up climate action, it also acknowledges that tackling climate change is an objective shared with the rest of the international community. For the past ten years, strategic partnerships have been forged with external sources of finance that are also looking to invest in low-carbon and climate-resilient development. Doing this has contributed to the Banks objective of mobilizing additional resources for climate action while also strengthening its position as a leading partner to accelerate climate innovation in many fields. From climate-smart technologies and resilient infrastructure to institutional reform and financial mechanisms, IDB's use of external sources of finance is helping countries in LAC advance toward meeting their international climate change commitments. This report collects a series of insights and lessons learned by the IDB in the preparation and implementation of projects with climate finance from four external sources: the Climate Investment Funds (CIF), the Forest Carbon Partnership Facility (FCPF), the Green Climate Fund (GCF) and the Global Environment Facility (GEF). It includes a systematic revision of their design and their progress on delivery, an assessment of broader impacts (scale-up, replication, and contributions to transformational change/paradigm shift), and a set of recommendations to optimize the access and use of these funds in future rounds of climate investment. The insights and lessons learned collected in this publication can inform the design of short and medium-term actions that support “green recovery” through the mobilization of investments that promote decarbonization.

Oxon Run Parkway (OXRN) is a 51-hectare (126-acre) natural area within Washington, D.C. administered by the National Park Service under National Capital Parks East (NACE). The original plan called for a road, slated to follow Oxon Run stream, but this never came to fruition; despite this, the moniker stuck. The majority of the original Oxon Run Parkway is managed by the District of Columbia. The section of Oxon Run Parkway under NPS jurisdiction contains wetlands and forests, as well as the only McAteean magnolia bogs still remaining in the District. The lower Cretaceous Potomac Group, known as one of the few dinosaur-bearing rock units on the east coast of North America, crops out within Oxon Run. One of the most prevalent fossil-bearing resources are the siderite, or “bog iron” sandstone slabs that sometimes preserve the footprints or trackways of various vertebrates, including dinosaurs. Such trackways have been reported from Potomac Group outcrops throughout the Atlantic Coastal Plain of Maryland and Virginia. In 2019, National Capital Parks-East took possession of such a track, referred to a dinosaur, collected by paleontologist Dr. Peter Kranz. This report was compiled after a paleontological survey of Oxon Run Parkway and is intended as a supplement to the National Capital Parks East Paleontological Resource Inventory (Nelson et al. 2019). This report contains information on the history of Oxon Run Parkway and its geology, as well as discussion of the fossil track.

The objective of this study was to track trends in the signs of higher-quality addiction treatment as defined by the National Institute on Drug Abuse, the National Institute on Alcohol Abuse and Addiction, and the Substance Abuse and Mental Health Services Administration. We analyzed the National Survey of Substance Abuse Treatment Services from 2007 through 2017 to determine the percent of facilities having the characteristics of higher quality. We analyzed the percent by state and over time. • We found improvements between 2007 and 2017 on most measures, but performance on several measures remained low. • Most programs reported providing evidence-based behavioral therapies. • Half or fewer facilities offered medications for opioid use disorder; mental health assessments; testing for hepatitis C, HIV, and sexually transmitted diseases; self-help groups; employment assistance; and transportation assistance. • There was significant state-level variation across the measures.
