Abstract Context-awareness is an enabling technology of pervasive computing that allows applications to adapt themselves in responseto contexts (e.g. activity, location, temperature level, etc.). However, an issue of user conflicts in context-aware applicationsmay arise when multiple users want to access the same application. Our research focuses on this issue and proposes aconflict resolution approach that resolves the conflicts in context-aware home applications. The proposed approach takes intoconsideration the users’ special case contexts (e.g. illness of user) along with their priorities and preferences. The proposedapproach is also useful in cases where multiple users with multiple special cases try to access one application or service.To show the usefulness of the proposed approach, we have integrated the proposed conflict manager with the UbiREAL, asimulated context-aware home environment. The conflict manager utilizes different strategies and different approaches toresolve user conflicts according to the involved situation to suit the need of the family. The prototype evaluation shows thatthe users are satisfied with the proposed system and suggests that the use of users’ special case contexts in detecting andresolving the user conflicts is essential and necessary in the context-aware smart home environments.

An investigation is presented of 87 Danish infants born to 62 drugaddicted mothers who had been pregnant altogether 145 times. In Denmark all pregnant women are offered prophylactic examinations, sometimes by their family doctor, sometimes by the midwife and in special cases by the obstetric clinic. Despite the fact that this antenatal care is considered especially important, not least for the addicted, pregnant woman, these offers were only poorly utilised. There were four perinatal deaths, of which two were stillbirths, further 3 infants died later as a result of abuse or neglect. After discharge from hospital only 43 infants lived at home with their mothers. The rest were either voluntarily or compulsorily placed with the mothers' parents, in family care, or in a childrens home. Only 2 infants were adopted. After their return home from the labour wards the mothers took little advantage of the prophylactic paediatric examinations and the vaccination program which are offered free by the family doctor to all children of pre-school age. The same was true regarding domiciliary visits by the health visitor.

Momentary Assessment

BACKGROUND Ecological momentary assessment (EMA) is an innovative tool to capture in-the-moment health behaviors as people go about their regular lives. EMA is an ideal tool to measure weight-related behaviors, such as parent feeding practices, stress, and dietary intake, as these occur on a daily basis and vary across time and context. A recent systematic review recommended standardized reporting of EMA design for studies that address weight-related behaviors. OBJECTIVE This manuscript describes in detail the EMA design of the Family Matters study. METHODS Family Matters is an incremental, two-phased, mixed-methods study conducted with a racially/ethnically diverse and immigrant/refugee sample from largely low-income households designed to examine the risk and protective factors for childhood obesity in the home environment. The Family Matters study intentionally recruited White, Black, Hmong, Latino, Native American, and Somali parents with young children. Parents in Phase I of the study completed eight days of EMA on their smart phones, which included 1) signal-contingent surveys (e.g., asking about the parent’s stress at the time of the survey); 2) event-contingent surveys (e.g., descriptions of the meal the child ate); 3) end-of-day surveys (e.g., overall assessment of the child’s day).cribes in detail the EMA design of the Family Matters study. RESULTS A detailed description of EMA strategies, protocols, and methods used in Phase I of the Family Matters study is provided. Compliance with EMA surveys and participant time spent completing EMA surveys is presented, stratified by race/ethnicity. Additionally, lessons learned while conducting Phase I EMA are shared to document how EMA methods were improved and expanded upon for Phase II. CONCLUSIONS Results from this study provide an important next step in identifying best practices for EMA use in assessing weight-related behaviors in the home environment.

Stimulation Of

The application of learning programs from home as an effort to reduce the transmission of the covid virus has brought about several phenomena in the field, including learning stimulation that is not carried out optimally, parents feel very bothered, and children are depressed and so on. All of this happened allegedly because some parents did not understand the approach to learning in early childhood. This research uses a literature study approach by utilizing various sources, both printed and online. From the results and discussion, it can be concluded that; 1. To optimize the results of intelligence stimulation/learning done at home, parents must understand the characteristics of early childhood learning in general, including children who like to play, each child is unique, and children like to imitate people in their environment. 2. Learning will take place well if parents understand and adapt the interests or tendencies of each child. 3. Every available space/spot in the home environment can be a fun place for intelligence stimulation for children if parents have sufficient understanding of the characteristics of an early child and the different interests of each child.

SummaryThe development during the last two decades of analytical techniques for the solution of problems relating to the optimisation of rocket trajectories is outlined and the present position in this field of research is summarised. It is shown that the determination of optimal trajectories in a general gravitational field can be expressed as a Mayer problem from the calculus of variations. The known solution to such a problem is stated and applied, first to the special case of the launching of an artificial satellite into a circular orbit with minimum expenditure of propellant and, secondly, to the general astronautical problem of the economical transfer of a rocket between two terminals in a gravitational field. The special cases when the field is uniform and when it obeys an inverse square law of attraction to a point are then considered, and the paper concludes with some remarks concerning areas in which further investigations are necessary.

A general similarity solution for water-entry problems of a wedge with its inner angle fixed and its sides in expansion is obtained with flow detachment, in which the speed of expansion is a free parameter. The known solutions for a wedge of a fixed length at the initial stage of water entry without flow detachment and at the final stage corresponding to Helmholtz flow are obtained as two special cases, at some finite and zero expansion speeds, respectively. An expanding horizontal plate impacting a flat free surface is considered as the special case of the general solution for a wedge inner angle equal to ${\rm\pi}$. An initial impulse solution for a plate of a fixed length is obtained as the special case of the present formulation. The general solution is obtained in the form of integral equations using the integral hodograph method. The results are presented in terms of free-surface shapes, streamlines and pressure distributions.

One of the critical situations facing the society across the globe is the problem of elderly homecare services (EHS) due to the aggravation of the society coupled with diseases and limited social resources. This problem has been typically dealt with by manual assistance from caregivers and/or family members. The emerging Ambience Intelligence (AmI) technology suggests itself to be of great potential for EHS applications, owing to its strength in constructing a pervasive computing environment that is sensitive and responsive to the presence of human users. The key challenge of AmI implementation lies in context awareness, namely how to align with the specific decision making scenarios of particular EHS applications. This paper proposes a context-aware information model in a smart home to tackle the EHS problem. Mainly, rough set theory is applied to construct user activity models for recognizing various activities of daily living (ADLs) based on the sensor platform constructed in a smart home environment. Subsequently, issues of case comprehension and homecare services are also discussed. A case study in the smart home environment is presented. Initial findings from the case study suggest the importance of the research problem, as well as the feasibility and potential of the proposed framework.

Abstract We study a family of harmonic univalent functions in the open unit disc defined by using post quantum calculus operators. We first obtained a coefficient characterization of these functions. Using this, coefficients estimates, distortion and covering theorems were also obtained. The extreme points of the family and a radius result were also obtained. The results obtained include several known results as special cases.

Juvenile delinquency is one of the prevalent issues of modern society. The purpose of this study was to compare the family environment and self esteem of delinquent and normal boys. Sample comprised of 30 delinquent and 30 normal boys. Their age ranging from 11-15 years. The data was gathered by using Home environment inventory (Dr. Misra S K) and Rosenberg self-esteem scale (Rosenberg, 1965).Home environment inventory was used to measure the psycho-social climate of home as perceived by children. By using t-test, it was found that there is significant difference between home environment of delinquents and normal boys in the following dimensions-control, protectiveness, punishment, conformity, social isolation, reward, deprivation of privileges, nurturance and rejection. It was also found that there is significance difference between self-esteem of delinquents and normal boys.

Family Of Distributions

In this work, a new family of distributions, which extends the Beta transmuted family, was obtained, called the Modified Beta Transmuted Family of distribution. This derived family has the Beta Family of Distribution and the Transmuted family of distribution as subfamilies. The Modified beta transmuted frechet, modified beta transmuted exponential, modified beta transmuted gompertz and modified beta transmuted lindley were obtained as special cases. The analytical expressions were studied for some statistical properties of the derived family of distribution which includes the moments, moments generating function and order statistics. The estimates of the parameters of the family were obtained using the maximum likelihood estimation method. Using the exponential distribution as a baseline for the family distribution, the resulting distribution (modified beta transmuted exponential distribution) was studied and its properties. The modified beta transmuted exponential distribution was applied to a real life time data to assess its flexibility in which the results shows a better fit when compared to some competitive models.

Reay's relaxed Tverberg conjecture and Conway's thrackle conjecture are open problems about the geometry of pairwise intersections. Reay asked for the minimum number of points in Euclidean $d$-space that guarantees any such point set admits a partition into $r$ parts, any $k$ of whose convex hulls intersect. Here we give new and improved lower bounds for this number, which Reay conjectured to be independent of $k$. We prove a colored version of Reay's conjecture for $k$ sufficiently large, but nevertheless $k$ independent of dimension $d$. Pairwise intersecting convex hulls have severely restricted combinatorics. This is a higher-dimensional analogue of Conway's thrackle conjecture or its linear special case. We thus study convex-geometric and higher-dimensional analogues of the thrackle conjecture alongside Reay's problem and conjecture (and prove in two special cases) that the number of convex sets in the plane is bounded by the total number of vertices they involve whenever there exists a transversal set for their pairwise intersections. We thus isolate a geometric property that leads to bounds as in the thrackle conjecture. We also establish tight bounds for the number of facets of higher-dimensional analogues of linear thrackles and conjecture their continuous generalizations.
