Introdução: o ciclo de sono-vigília é o comportamento rítmico circadiano mais onipresente nos humanos. Ele é estabelecido por um sistema temporizador circadiano endógeno que é regulado pela presença ou ausência de luz no ambiente. O comportamento em relação a dormir e acordar varia entre os indivíduos e essa característica nomeia-se cronotipo. Efeitos negativos à saúde têm sido associados ao cronotipo que apresenta horários para iniciar e terminar o sono mais tarde. A hipótese considerada para explicar esses achados é de que demandas sociais, que não levam em conta essa variabilidade individual, sejam mediadoras dessa relação. Objetivos: avaliar a associação entre cronotipo e saúde mental (bem-estar psicológico e sintomas depressivos) levando-se em conta fatores demográficos (sexo e idade) e as rotinas de escola ou trabalho. Materiais e métodos: estudos transversais aninhados a um estudo epidemiológico em uma amostra de indivíduos do Vale do Taquari, no sul do Brasil. Na primeira avaliação, 6.506 participantes foram avaliados quanto a variáveis demográficas, dados de saúde, sintomas depressivos (Inventário de Depressão de Beck – BDI) e cronotipo (Questionário de Cronotipo de Munique – MCTQ). Na segunda etapa...

As crianças dos dois aos três anos vivem num mundo simples e pouco concreto. Cabe aos adultos suscitar-lhes o interesse para o mundo exterior, proporcionando-lhes experiências e ensinamentos positivos e inesquecíveis. Os educadores de infância surgem, determinantemente, com um papel fundamental e orientador do bem-estar físico, mental e emocional da criança. É nesta sequência que nasce o presente relatório. O estágio realizado numa sala de creche na cidade de Portalegre despontou o interesse pelas rotinas e pela implicação das mesmas nas vidas das crianças. O dia-a-dia das crianças na creche desenrola-se de acordo com um conjunto de rotinas e atividades que se devem planear cuidadosamente e promover de forma a favorecer o desenvolvimento da criança e a assegurar-lhe um constante bem-estar. A rotina diária impera como um meio de aprendizagem e desenvolvimento integral e, tal como afirmam Hohmann & Weikart (2011), “oferece um enquadramento estável no qual as crianças (…) podem sem perigo iniciar, reflectir sobre, modificar e expandir as experiências de aprendizagem pela acção” (pág.227). Tendo por base a pedagogia High Scope para a creche foram desenvolvidas, ao longo das Unidades Curriculares de Prática de Ensino Supervisionada...

Infobuttons have been proven as an effective means for providing quick, context-specific links to pertinent information resources at the point of care. Current infobutton manager implementations, however, lack the ability to exchange metadata, are limited to a relatively small set of information providers, and are targeted primarily for a clinician audience. As part of a local effort to implement infobuttons for patient use via a tethered personal health record, we present a series of metadata extraction routines. These routines were constructed to extract key pieces of information from health information providers on the Internet, including content coverage, language availability, and readability scores. The extraction routines were tested using thirty different disease conditions against eight different providers. The routines yielded 183 potential infobutton targets and associated metadata for each. The capabilities of the extraction routines will be expanded to cover new types of metadata in the future.

Public interest in the quality and safety of health care has spurred examination of specific organizational routines believed to yield risk in health care work. Medication administration routines, in particular, have been the subject of numerous improvement projects involving information technology development, and other forms of research and regulation. This study draws from ethnographic observation to examine how the common routine of medication administration intersects with other organizational routines, and why understanding such intersections is important. We present three cases describing intersections between medication administration and other routines, including a pharmacy routine, medication administration on the next shift and management reporting. We found that each intersection had ostensive and performative dimensions; and furthermore, that IT-enabled changes to one routine led to unintended consequences in its intersection with others, resulting in misalignment of ostensive and performative aspects of the intersection. Our analysis focused on the activities of a group of nurses who provide technology use mediation (TUM) before and after the rollout of a new health IT system. This research offers new insights on the intersection of organizational routines...

Many daily routines and behaviors are related to the prevalence of obesity. This study investigated the association between routines and behaviors that act as protective factors related to lower prevalence of obesity in parents (BMI ≥ 30 kg/m2) and overweight in preschool children (BMI ≥ 85th percentile). Socio-demographic characteristics were assessed in relation to protective routines (PRs), and prevalence of obesity/overweight data from 337 preschool children and their parents. The two PRs assessed with parents included adequate sleep (≥7 h/night) and family mealtime routine (scoring higher than the median score). The four PRs assessed in children included adequate sleep (≥10 h/night), family mealtime routine, limiting screen-viewing time (≤2 h/day of TV, video, DVD), and not having a bedroom TV. Overall, 27.9% of parents were obese and 22.8% of children were overweight, and 39.8% of the parents had both parent PRs, and only 11.6% of children had all four child PRs. Results demonstrated that several demographic factors were significantly related to the use of PRs for parents and children. The lack of PRs was related to increased risk for overweight in children, but not for obesity in parents. However, in the adjusted models the overall cumulative benefits of using PRs was not significant in children either. In the multivariate adjusted logistic regression models...

Using mixed methods, this study examined the relationship of caregivers of children with disabilities’ psychological well-being (PWB) and their orchestration of daily routines within their ecological niche. Thirty-nine U.S. caregivers completed in-depth interviews, PWB Scales, and Family Time and Routines Index (FTRI). We used a multi-step analysis. Interview data was coded and vignettes created without knowledge of PWB and FTRI ratings. Next, the relationship of quantitative measures was analyzed. Four groups were created using FTRI-extent and PWB means: (1) low routine-low PWB, (2) low routine-high PWB, (3) high routine-low PWB, and (4) high routine-high PWB. We examined qualitative differences in key features between groups. Findings: Total PWB and FTRI scores were not significantly correlated, PWB Purpose in Life and FTRI-extent scores were moderately positively correlated, and PWB Environmental Mastery and FTRI-extent correlation approached significance. Qualitative findings describe caregivers’ structuring of routines, intensity of oversight, support in routines, management of dinner, paid work, and needs for respite. The four groups differed in paid work, household support, degree the child could self-occupy, Environmental Mastery...

Maintenance of family processes can protect parents, children, and families from the detrimental effects of extreme stressors, such as homelessness. When families cannot maintain routines and rituals, the stressors of poverty and homelessness can be compounded for both caregivers and children. However, characteristics of living situations common among families experiencing homelessness present barriers to the maintenance of family routines and rituals. We analyzed 80 in-depth interviews with parents who were experiencing or had recently experienced an instance of homelessness. We compared their assessments of challenges to family schedules, routines, and rituals across various living situations, including shelter, transitional housing programs, doubled up (i.e. living temporarily with family/friend), and independent housing. Rules common across shelters and transitional housing programs impeded family processes, and parents felt surveilled and threatened with child protective service involvement in these settings. In doubled up living situations, parents reported adapting their routines to those of the household and having parenting interrupted by opinions of friends and family members. Families used several strategies to maintain family rituals and routines in these living situations and ensure consistency and stability for their children during an otherwise unstable time.

Saccadic reaction time (SRT) is a widely used dependent variable in eye-tracking studies of human cognition and its disorders. SRTs are also frequently measured in studies with special populations, such as infants and young children, who are limited in their ability to follow verbal instructions and remain in a stable position over time. In this article, we describe a library of MATLAB routines (Mathworks, Natick, MA) that are designed to (1) enable completely automated implementation of SRT analysis for multiple data sets and (2) cope with the unique challenges of analyzing SRTs from eye-tracking data collected from poorly cooperating participants. The library includes preprocessing and SRT analysis routines. The preprocessing routines (i.e., moving median filter and interpolation) are designed to remove technical artifacts and missing samples from raw eye-tracking data. The SRTs are detected by a simple algorithm that identifies the last point of gaze in the area of interest, but, critically, the extracted SRTs are further subjected to a number of postanalysis verification checks to exclude values contaminated by artifacts. Example analyses of data from 5- to 11-month-old infants demonstrated that SRTs extracted with the proposed routines were in high agreement with SRTs obtained manually from video records...

We conducted an observational study of parent-child interaction in home activity settings (routines) of families raising young children with developmental disabilities and problem behavior. Our aim was to empirically investigate the construct validity of coercion in typical but unsuccessful family routines. The long-term goal was to develop an expanded ecological unit of analysis that may contribute to sustainable behavioral family intervention. Ten children with autism and/or mental retardation and their families participated. Videotaped observations were conducted in typical but unsuccessful home routines. Parent-child interaction in routines was coded in real time and sequential analyses were conducted to test hypotheses about coercive processes. Following observation, families were interviewed about the social validity of the construct. Results confirmed the presence of statistically significant, attention-driven coercive processes in routines in which parents were occupied with non-child centered tasks. Results partially confirmed the presence of escape-driven coercive processes in routines in which parent demands are common. Additional analysis revealed an alternative pattern with greater magnitude. Family perspectives suggested the social validity of the construct. Results are discussed in terms of preliminary...

Regularities in the word give rise to regularities in the way which we deal with the world. That is to say, we fall into routines. I have been studying the phenomena of routinization, the process by which institutionalized patterns of interaction with the world arise and evolve in everyday life. Underlying this evolution is a dialectical process of internalization. First you build a model of some previously unarticulated emergent aspect of an existing routine. Armed with an incrementally more global view of interaction, you can often formulate an incrementally better informed plan of attack. A routine is not a plan in the sense of the classical planning literature, except in the theoretical limit of this process. I am implementing this theory using running arguments, a technique for writing rule-based programs for intelligent agents. Because a running argument is compiled into TMS networks as it proceeds, incremental changes in the world require only incremental recomputation of the reasoning about what actions to take next. The system supports a style of programming, dialectival argumentation that had many important properties that recommend it as a substrate for large AI systems. One of these might be called additivity: an agent can modify its reasoning in a class of situations by adducing arguments as to why its previous arguments were incorrect in those cases. Because no side-effects are ever required...

This paper examines the processing of visual information beyond the creation of the early representations. A fundamental requirement at this level is the capacity to establish visually abstract shape properties and spatial relations. This capacity plays a major role in object recognition, visually guided manipulation, and more abstract visual thinking. For the human visual system, the perception of spatial properties and relations that are complex from a computational standpoint, nevertheless often appears immediate and effortless. This apparent immediateness and ease of perceiving spatial relations is, however, deceiving. It conceals in fact a complex array of processes highly specialized for the task. The proficiency of the human system in analyzing spatial information far surpasses the capacities of current artificial systems. The study of the computations that underlie this competence may therefore lead to the development of new more efficient processors for the spatial analysis of visual information. It is suggested that the perception of spatial relations is achieved by the application to the base representations of visual routines that are composed of sequences of elemental operations. Routines for different properties and relations share elemental operations. Using a fixed set of basic operations...

Active vision systems have the capability of continuously interacting with the environment. The rapidly changing environment of such systems means that it is attractive to replace static representations with visual routines that compute information on demand. Such routines place a premium on image data structures that are easily computed and used. The purpose of this paper is to propose a general active vision architecture based on efficiently computable iconic representations. This architecture employs two primary visual routines, one for identifying the visual image near the fovea (object identification), and another for locating a stored prototype on the retina (object localization). This design allows complex visual behaviors to be obtained by composing these two routines with different parameters. The iconic representations are comprised of high-dimensional feature vectors obtained from the responses of an ensemble of Gaussian derivative spatial filters at a number of orientations and scales. These representations are stored in two separate memories. One memory is indexed by image coordinates while the other is indexed by object coordinates. Object localization matches a localized set of model features with image features at all possible retinal locations. Object identification matches a foveal set of image features with all possible model features. We present experimental results for a near real-time implementation of these routines on a pipeline image processor and suggest relatively simple strategies for tackling the problems of occlusions and scale variations. We also discuss two additional visual routines one for top-down foveal targeting using log-polar sensors and another for looming detection...

Thesis (Ph.D.)--University of Rochester. Dept. of Computer Science, 1998. Simultaneously published in the Technical Report series.; To meet the demands of driving in complex environments, the perception subsystem of an intelligent vehicle must be able to extract the information needed for behaviors from the input video stream. An attractive way of achieving this is to have a library of basic image processing sub-functions (visual routines), which can be composed to subserve more elaborate goal-directed programs. The crucial compositional capability allows the visual routines to span the huge space of different task goals. The visual routines presented here are developed in a unique platform. The view from a car driving in a simulated world is fed into a Datacube pipeline video processor. The integration of photo-realistic simulation and real-time image processing represents a proof of concept for a new system design that allows testing computer vision algorithms under controllable conditions, thus leading to rapid prototyping. In addition to the simulations, the routines are also tested on similar images generated by driving in the real world to assure the generalizability of the simulation. The simulator can also be used with human subjects who can drive a kart through the virtual environment while wearing head mounted displays (HMDs). A unique feature of the driving simulator we have built is the ability to track eye movements within a freely moving HMD. This allows the assessment of exigencies in complex situations that can be used to guide the development of automated routines.

Research into the phenomena of social innovation has long focused on what it is and why people become engaged in this form of behaviour. Another piece of the theoretical jigsaw however, requires understanding how this type of innovation is enacted by organizations. This article therefore looks at the means in which Not-for-Profit (NFP) social ventures pursuing socially innovative activities develop the necessary capabilities to innovate. We use the multidimensional theoretical construct of absorptive capacity (ACAP) and the evolutionary economics concept of organizational routines to analyse 16 case studies of innovative NFP ventures in the UK and Australia. Our results show that these organizations have a unique mediating function in the social innovation process by configuring internal and external ACAP routines to combine user and technological knowledge flows. Other key findings highlight the emergence of internal tensions as established routines are supplanted in order to ‘professionalize’ the socially innovative NFP venture, and between routines underpinning knowledge sharing and resource allocation. We conclude by proposing some research directions for those taking forward the study of social innovation.; Dominic M. Chalmers...

PURPOSE Complementary and alternative medicine (CAM) is frequently used in cancer patients, often with contribution of the significant others (SOs), but without consultation of healthcare professionals. This research explored how cancer patients integrate and maintain CAM use in their everyday life, and how SOs are involved in it. METHODS In this qualitative study, male participants were selected from a preceding Australian survey on CAM use in men with cancer (94 % response rate and 86 % consent rate for follow-up interview). Semistructured interviews were conducted with 26 men and 24 SOs until data saturation was reached. Interview transcripts were coded and analyzed thematically, thereby paying close attention to participants’ language in use. RESULTS A major theme associated with high CAM use was “CAM routines and rituals,” as it was identified that men with cancer practiced CAM as (1) functional routines, (2) meaningful rituals, and (3) mental/spiritual routines or/and rituals. Regular CAM use was associated with intrapersonal and interpersonal benefits: CAM routines provided men with certainty and control, and CAM rituals functioned for cancer patients and their SOs as a means to create meaning, thereby working to counter fear and uncertainty consequent upon a diagnosis of cancer. SOs contributed most to men’s uptake and maintenance of dietary-based CAM in ritualistic form resulting in interpersonal bonding and enhanced closeness. CONCLUSIONS CAM routines and rituals constitute key elements in cancer patients’ regular and satisfied CAM use...

Management of cystic fibrosis (CF) is burdensome and adherence is often suboptimal. Family routines are associated with adherence and health outcomes in other disease populations. Few studies have examined routines in CF. The study's aim was to describe parent experiences developing and utilizing CF care routines. Semi-structured interviews with a convenience sample of 25 parents of children under 13 years of age with CF were analyzed using phenomenological analysis. Three domains emerged: parent experiences developing a routine, support systems facilitating maintenance of routines, and challenges with maintaining care routines. Parents found routines difficult to establish, used trial and error, encountered barriers, and found support helpful to manage care demands. Some parents chose to deviate from their routine. Providing anticipatory guidance to promote the use of care routines and strategies to manage potential challenges may facilitate use of routines and improve CF management.

Eating routines are a compelling issue because recurring eating behaviors influence nutrition and health. As non-traditional and individualized eating patterns have become more common, new ways of thinking about routine eating practices are needed. This study sought to gain conceptual understanding of working adults' eating routines. Forty-two purposively sampled US adults reported food intake and contextual details about eating episodes in qualitative 24-hour dietary recalls conducted over 7 consecutive days. Using the constant comparative method, researchers analyzed interview transcripts for recurrent ways of eating that were either explicitly reported by study participants as “routines” or emergent in the data. Participants' eating routines included repetition in food consumption as well as eating context, and also involved sequences of eating episodes. Eating routines were embedded in daily schedules for work, family, and recreation. Participants maintained purposeful routines that helped balance tension between demands and values, but they modified routines as circumstances changed. Participants monitored and reflected upon their eating practices and tended to assess their practices in light of their personal identities. These findings provide conceptual insights for food choice researchers and present a perspective from which practitioners who work with individuals seeking to adopt healthful eating practices might usefully approach their tasks.

This extended abstract focuses on organizational routines as an emergent phenomenon of individual behavior within collectives. Micro foundations related to dynamics of performing and remembering organizational routines are based on psychological constructs such as procedural, declarative and transactive memory. Replicating the agent-based model “Dynamics of Performing and Remembering Organizational Routines” in a different programming language is used to analyze the model´s credibility. To enhance the replication transparency and quality the existing model is initially transferred into an ODD protocol before its re-implementation. If the model can be replicated without significant errors, it can be used in further research to examine organizational routines in accounting.

Currently, most image merger routines are judged on the enhanced appearance of the hybrid imagery that they create. Little or no quantitative analysis is given which represents a technique's ability to preserve the radiometry of the hybrid imagery. For this reason, a quantitative analysis of six multi-resolution, multitemporal, multi-sensor, multispectral image merger routines was performed. These techniques were designed to incorporate the high resolution spatial information of a panchromatic image with the spectral information of a low resolution multispectral image. The panchromatic imagery came from the French satellite Systeme Pour l'Observation de la Terre (SPOT) and the multispectral imagery came from the NASA Landsat Thematic Mapper (TM). This study served as a quantitative test of three commonly used merger techniques (intensity-hue-saturation (IHS) transformation method, principal component method, and high-pass filter technique) and three merger techniques developed by the Digital Image Processing and Remote Sensing (DIRS) laboratory at RIT (ratio method, extended regression method, and global regression method). These routines were judged on the basis of their radiometric integrity and their dependent and independent classification accuracies. Statistical analysis of these metrics showed that the DIRS global coefficient routine provided the best enhancements of the multispectral imagery for the scenes and testing metrics selected.
