Calgary assessment model: study of family units with child malnutrition

To describe the experience of using the Calgary Family Assessment Model in two family units with child malnutrition, as well as to construct their genogram and ecomap, analyzing the profile of the family structure. This is a case study carried out with two families, with a qualitative approach, developed in a reference unit for early childhood care, located in the city of Fortaleza-CE, from March to May 2023. ethical assessment with CAAE 66662422.8.0000.5049. Family 2 presented a higher risk of food insecurity, since only one of its components (F1) is the breadwinner. In addition, it was found that the therapies used in nutritional monitoring achieved greater adherence in Family 1, correlated with greater access to food, as well as the higher level of education of its members. However, through the application of the Calgary Model of Family Assessment, one can recognize the ability of families to solve problems, as well as inhibitions related to the educational nature that make it difficult to adhere to the interventions offered about child malnutrition.

MODELO CALGARY DE AVALIAÇÃO FAMILIAR: MULHERES EM SITUAÇÃO DE VIOLÊNCIA E REVOGAÇÃO DE MEDIDAS PROTETIVAS

ABSTRACT Objective: To understand the strengths and weaknesses of the families of women in situations of violence who have had their emergency protective measures revoked. Method: descriptive research based on the Calgary Family Assessment Model, in the context of a Women’s Police Station in a municipality in the interior of São Paulo, Brazil, carried out between September and November 2021, with four families of women who revoked the protective measure. Family structure, development, and functionality data were collected and analyzed according to the Calgary Model. Results: the families have similarities that include socio-economic aspects, low schooling, alcohol use, conflicting family relationships, and transgenerational relationships that, due to their fragility, perpetuate the cycle of violence. However, the social benefits, religious support, and family members were strengths. Conclusion: The Calgary Family Assessment Model guides nurses in proposing care plans consistent with domestic violence’s complexities.

Estimation and impact of GLONASS inter-frequency code bias in single-frequency precise point positioning

The current GLONASS system suffers from the inter-frequency code bias (IFCB) and the inter-frequency phase bias (IFPB) due to its employment of the frequency division multiple access (FDMA) technology. The IFCB affects the code observation’s accuracy and further degrades the positioning accuracy, while the IFPB can be absorbed into the float ambiguity term. With increasing demand on precise point positioning (PPP) in mass market applications using low-cost single-frequency (SF) receivers, the impact of IFCB on SF-PPP with low-cost receivers need to be investigated. In this paper, we propose the use of the University of Calgary (UofC) model to estimate the IFCB in SF-PPP. The feasibility of the proposed approach is first verified using GNSS observations from the IGS stations. Comparing to the traditional SF-PPP model, the UofC model enables more stable IFCB estimations with 80.2% of the maximum changes less than 1.0 ns within one week. Then, the stability of IFCB in the low-cost SF receiver is analyzed with static data collected with u-blox M8T, and the STandard Deviation (STD) of IFCB for each satellite within 5 days is less than 1.5 ns when applying real-time orbit, clock and ionospheric corrections. Further, it’s verified that the power off won’t affect the IFCB’s value significantly in the low-cost receiver. Finally, six different strategies are designed to evaluate the impact of the GLONASS IFCB on SF-PPP. Comparing to those strategies ignoring IFCB, the strategies considering IFCB in SF-PPP can improve the positioning accuracy in both static and kinematic tests.

Elderly victims of violence: family assessment through the Calgary model.

To understand the structure, development, and functionality of the family of the elderly victim of violence. Descriptive research with a qualitative approach, based on the Calgary Family Assessment Model. Four elderly people who suffered violence and their family members were assessed at home, from October to November 2019. Data analysis was based on the genogram and ecomap, as proposed in the model. It was found that the members of the four families had low schooling and financial difficulties. As for the social support network, the neighbors, the health unit and the Church stood out. The members of each family nucleus expressed feelings of fear, insecurity, anger, nervousness, sadness and impotence, resulting from the conflict between the couple. In the assessed families, weaknesses and potentialities in the structure, development and functioning are highlighted, which must be considered in the elaboration of the care plan.

Débats autour des races canines et de la santé publique à Montréal et au Québec (2016-2019).

We examine the public policies that have been formulated to reduce the incidence of dog bites. We do so to encourage the adoption of policies aligned with One Health promotion. This case-study research involved an ethnographic approach. Our qualitative analysis derived from participant observation, policy documents, media coverage, and interviews with stakeholders in Montreal (Quebec). Following on from a human fatality due to dog bite injuries, the City of Montreal decided to ban certain types of dogs based on their 'breed.' In the ensuing discussions, the 'Calgary model' emerged as an alternative to breed-specific legislation. These discussions led to a change in policy direction for Montreal, and for Quebec as a whole. Furthermore, we discerned marked improvements with respect to intersectoral coordination in the wake of this controversy. 'Policy mobilities' offer a useful conceptual apparatus for understanding how public policies for dog bite prevention are polarized around controversial proposals, to the detriment of discussions that focus on policy implementation.

A social capital view of an Olympic and Paralympic Games bid exploration process

ABSTRACT Research question: The purpose of this study is to examine the Olympic and Paralympic bid exploration process adopted by Calgary, Canada (‘Calgary Model’) to explore whether it provides a template on how future communities could leverage bid exploration processes to generate social capital though increased network connectivity and community ownership. In doing so, we examine the four research questions: Research Question 1: How did the Calgary Model embed community values as central to all decision-making processes? Research Question 2: How did the Calgary Model engage diverse stakeholders, particularly community interest groups, in the strategic activities? Research Question 3: How did the Calgary Model empower communities to become agents of change? Research Question 4: How did the Calgary Model provide sustained open communication towards mutual learning? Research methods: Guided by social capital theory, the researchers conducted 19 in-depth, one-on-one interviews with a sample of individuals engaged in the Calgary bid exploration process. Results and findings: The results identified ten composite themes with an overall conclusion that the process Calgary used did not sufficiently generate social capital through maximizing network connectivity and community ownership. Implications: Resulting from our data analysis we developed a conceptual social capital assessment tool and five principles to support event organizers in designing processes that help to maximize the generation of community social capital.

Family dynamics and social network of families of children with special needs for complex/continuous cares.

To describe the family dynamics and the social support network for families of children with special needs of multiple, complex and continuous care. A descriptive study of a qualitative approach, carried out in Maringá - PR, having as theoretical and methodological reference the Calgary Model of Family Assessment (CMFA). Data was collected through semi-structured audio-video interviews, carried out in the homes, together with 11 family caregivers of 13 children. Data is presented in the following categories: structural, developmental and functional evaluation, which show the changes in the family routine and the needs for the adjustment of the roles of its members, in order to better implement the care at home. Using the CMFA made it possible to identify and understand the composition, fragilities and potentialities of the family, as well as the relationships among its members and rearrangements to better enable care at home. This information favors interventions congruent with the needs of these families.

P007: Development of provincial recommendations for domestic violence screening in emergency departments and urgent care settings in Alberta

Introduction: Alberta has one of the highest rates of domestic violence (DV) in the country. Emergency departments (EDs) and urgent care centres (UCCs) are significant points of opportunity to screen for DV and intervene. In Alberta, the Calgary Zone began a universal education and direct inquiry program for DV in EDs and UCCs for patients > = 14 years in 2003. The Calgary model is unique in that (a) it provides universal education in addition to screening and (b) screening is truly universal as it includes all age groups and genders. While considering expanding this model provincially, we engaged in the GRADE Adolopment process, to achieve multi-stakeholder consensus on a provincial approach to DV screening, as herewith described. Methods: Using GRADE, we synthesized and rated the quality of evidence on DV screening and presented it to an expert panel of stakeholders from the community, EDs, and Alberta Health Services. There was moderate certainty evidence that screening improved DV identification in antenatal clinics, maternal health services and EDs. There was no evidence of harm and low certainty evidence of improvement in patient-important outcomes. As per Adolopment, the expert panel reviewed the evidence in the context of: a) values and preferences b) benefits and harms, and c) acceptability, feasibility, and resource implications. Results: The panel came to a unanimous decision to conditionally recommend universal screening, i.e., screening all adults above 14 years of age in EDs and UCCs. By conditional, the panel noted that EDs and UCCs must have support resources in place for patients who screen positive to realize the full benefit of screening and avoid harm. The panel deemed universal screening to be a logistically easier recommendation, compared to training healthcare professionals to screen certain subpopulations or assess for specific symptoms associated with DV. The panel noted that despite absence of evidence that screening would impact patient-important outcomes, there was evidence that effective interventions following a positive screen could positively impact these outcomes. The panel stressed the importance of evidence creation in the context of absence of evidence. Conclusion: A GRADE Adolopment process achieved consensus on provincial expansion of an ED-based DV screening program. Moving forward, we plan to gather evidence on patient-important outcomes and understudied subpopulations (i.e. men and the elderly).

Alcoholic beverage users: structural and functional aspects based on the Calgary Model

Objective: to describe the structural and functional aspects and support networks of families living with users of alcoholic beverages. Methods: a cross-sectional descriptive study, methodological reference of the Calgary Family Assessment Model, based on semi-structured interviews with the genogram and eco-map tools, carried out with relatives of four construction workers hospitalized for injuries related to alcoholic beverage use, and notified to an information and toxicological assistance center. Results: there was a reduction of the children between the generations, but the use of drugs was expanding in the families. Distant and conflicted family relationships were found. The neighborhood support network was strongly linked, but the support of Primary Health Care was a weak link. Conclusion: the structural and functional evaluation of the families propitiated knowledge for health promotion, treatment and recovery processes to restore fragile family relationships.

Conclui-se que o caso relatado contribui para orientar o trabalho interprofissional com famílias para produção de cuidados na atenção básica.

Triple-Frequency Combining Observation Models and Performance in Precise Point Positioning Using Real BDS Data

Although precise point positioning (PPP) is a well-established and promising technique with the use of precise satellite orbit and clock products, it requires a long convergence time to reach a centimeter-level positioning accuracy. The availability of triple-frequency observations from a modernized global navigation satellite system (GNSS) constellations makes it possible to improve performance by formulating new observation models. The contribution of this paper is to propose two new observation models using triple-frequency data. The first model (UofC3) is the triple-frequency extension of dual-frequency University of Calgary model. The second model (UofB) is a combining observation model with five-dimensional observation equations. Thereafter, by theoretically analyzing the dimension of the triple-frequency observation models, all feasible triple-frequency observation models are systematically found out. Finally, the positioning experiments with 3-h observation period using real data at four BeiDou Navigation Satellite System (BDS) Asia-Pacific distributed reference stations on the day of the year (DOY) 42-48, 2018 are conducted to compare the performance of observation models. The results show that the triple-frequency models have less convergence time than the dual-frequency models. Meanwhile, most of the triple-frequency models have approximate convergence time in an experiment. Furthermore, UofB, which is one of the most stabilized observation models as well as uncombined observation model with the triple-frequency data (UC3), has less processing time than UC3. Compared with UofB, UofC3 has less processing time with sacrificing stability. These results show the significance of the UofB and UofC3 for future PPP applications in modernized GNSS.

Evaluation of the implementation process of family nursing in oncology

The confrontation with a life-threatening cancer disease and the resulting consequences are a great burden for patients as well as for their family members. Family nursing based on the Calgary Model was implemented on a German oncological inpatient unit in order to strengthen the family's ability to self-help. The objectives were a) to systematically record, evaluate and if necessary to modify the implementation process, b) to highlight promoting and inhibiting factors and c) to derive recommendations for transferability to other oncological units. The implementation process was examined by means of two group interviews with nurses, five interviews with other members of the treatment team, and observations of, in each case four, family assessments, family interviews and family-related team meetings. Family nursing could be implemented in a modified form. Genograms and ecomaps have become part of the admission interview. In family interviews, needs of the entire family were determined with the help of circular communication. Family-related team meetings were carried out according to an adapted method of the reflecting team. The complete implementation of family nursing was impeded by the lack of professional consulting competences of the nursing staff, the system of nursing care delivery and lack of time. An implementation of family nursing in other oncological units is recommended under modified preconditions.

A modified un-combined model to improve the performance of precise point positioning: model and test results

Precise point positioning (PPP) can achieve high-accuracy point solution using un-differenced code and carrier phase observations. Many PPP models have a higher measurement noise and multipath effects, resulting in a long time to obtain sub-decimeter to centimeter positioning accuracy during a short duration. This paper will address a modified un-combined (MUC) model based on phase–phase geometry-free combination in addition to code–phase ionosphere-free combination and original carrier phase observations. The observation system composed by the new combinations has a lower measurement noise and orbit error level compared with the un-combined (UC) model, University of Calgary (UofC) model and standard un-differenced ionosphere-free combined (UD) model. Moreover, it can capture the changing characteristics of atmospheric delays between epochs as constraints to accelerate the filter convergence. We use the data sets from about 114 international GNSS service reference stations to analyze the performance of the MUC model. Numerical results show that the MUC model generally yields the best performance when the observation duration is short. For the 0.5 h duration observation data sets, about 70.2 % of all 6912 convergence tests are convergent, which is an increase by 19.2, 2.8 and 49.3 % points compared with the UC, UofC and UD models, respectively. For the common convergence parts of all the test data sets, the mean convergence time of the MUC model is significantly reduced by 22.9, 9.6 and 35.3 %, and the percentage of the 2D position biases within 0–5 cm is increased by 16.0, 3.4 and 55.0 %, respectively, compared with the UC, UofC and UD models. Therefore, the proposed PPP model is more beneficial for the PPP user to quickly obtain sub-decimeter to centimeter positioning accuracy during a short duration.

Avaliação de famílias com mais de uma mulher mastectomizada: estudo de caso

Aim: to evaluate the structure, development and functionality of families with more than one woman with breast malignancy and mastectomies. Method: this is a qualitative study involving the theoretical basis of structural, developmental and functional categories, as proposed by the Calgary model, and using case study as a methodological strategy. Data was collected through home visits with 10 families with mastectomized women, between August 2014 and February 2015.Results: conflicting subsystems were present in only two families and all presented with support network elements from systems other than family, including neighbors and health institutions. In the care process, the link established that support and frequent monitoring helped to ease some of the difficulties experienced. Conclusion: it is believed that the Calgary model enables a broader view of the family to be taken, better understanding in terms of internal and external relations, and enabled weaknesses and strengths to be balanced.

Family Structure Assessment Of Patients In Palliative Home Care

This study aims to examine the family structure of patients in palliative home care in the light of the Calgary Family Assessment Model (CFAM). This is a qualitative research, conducted in the residences of patients enrolled in the Palliative Care Unit and Pain Treatment (PCUP) of a university hospital located in Recife/Pernambuco, Brazil, in the period from May to July 2014. The sample consisted of five patients enrolled in the PCUP and five family caregivers. Data collection was performed through an interviewing technique using two instruments: the genogram and eco-map. The empirical material was analyzed in the light of the Calgary Model of Family Assessment. The application of the Model demonstrated external family structure relationship with the non-existent neighborhood; support network in diverse health, with very strong relationship with the PCUP highlighting the link with nursing professional; weak relationship concerning Basic Health Unit and strong connection to the church. The obtained data suggest that each researched family has demands to be thought of as focus of nursing care and have faith as a resource for coping with the disease. It follows that the application of CFAM has highlighted the intra-family ties and the relations established with the support networks, signaling strategies to optimize patient care without a therapeutic possibility of cure and their family.
