Managing hypertension is not only concerned with lowering blood pressure by using antihypertensive medications;it also aims to minimize its consequences through adopting self-care practices. Compliance with self-care practices among patients with hypertension is considered a multidimensional phenomenon. The phenomenon of hypertension has been studied quantitatively, however;little qualitative studies were conducted to understand the compliance with self-care among patients with hypertension. Aim: To understand the process that patients with hypertension go through to comply with self-care practices. Methods: This study used a qualitative design that followed constructivist grounded theory approach;purposive sampling was used to recruit participants from cardiac clinics;semi structured, in-depth and face-to-face interview was used as a major method for data collection. Findings: Four participants with hypertension participated in this study;the phenomena of self-care was identified as the central phenomena;the start of the disease was identified as a casual condition;beliefs toward hypertension disease, beliefs toward self-care practices, knowledge and awareness regarding hypertension disease and self-care practices were identified as strategies;experiencing self-care practices was identified as consequence and being patients with hypertension in a social context. Conclusions: The process of compliance with self-care has a path of actions and interactions. The process started from the moment of diagnosis where the patients start to think about self-care. The absence of health care context leads to varying level of compliance with self-care among patients with hypertension. This indicated the need for more effective patient and health care provider relationship, education and awareness campaign.展开更多

Finally, 12 secondary indicators (categories) and 4 primary indicators (main categories) were obtained, among which the primary indicators were management factors, emergency response, construction factors and personnel factors. From the weight value calculated by analytic hierarchy process, we can see that management factors and emergency response have great influence on the emergency evacuation capacity of subway stations. Therefore, we should focus on management factors and emergency response to improve the emergency evacuation capacity of subway stations.展开更多

The study was qualitative in nature with a phenomenological interpretive paradigm dominating the philosophical approach. The research methods adopted combined life story and grounded theory. As far as the author has been able to determine there are very few, if any studies which have applied this approach specifically to this area of research which investigated the influence life history has on attitude to lifelong learning. Twenty five respondents were interviewed in face-to-face informal interviews. The main aim was to elicit the respondent＇s subjective interpretation of the interaction between school, family, work, and learning within their lives. The researcher was then able to identify when they occurred and what or who made them particularly meaningful. This paper describes how initial decisions were made regarding the substantive area for the research. Sampling technique and method for collecting the data is discussed and a worked example is given of how the data was analysed. It is intended that this paper will give an insight into the challenge of combining these two much debated methods of research. The empirical data lead to some interesting findings which educators and policy makers will find helpful in order to strengthen the school, college, and workplace interface.展开更多

Surgery performed under regional or local anaesthesia allows the patient to remain conscious during the procedure and is rather common in Swedish healthcare today. Aim: The aim was to obtain a deeper understanding of the main concerns of operating theatre nurses (OTN) when caring for conscious patients during the intraoperative phase. Methods: Interviews were conducted with 23 OTNs from five different hospitals in Sweden and analysed according to grounded theory. Findings: The main concern among the OTNs was to take the patient in consideration. The core category “achieve and maintain ethical treatment of patients” in the operating theatre (OT) was a strategy used throughout the intraoperative process. Ethical treatment was described as moral behaviour at different levels and included the team’s behaviour, respectful and individualised patientcare, and the working-morale of the professionals. Being vigilant and being flexible were the categories related to the core category. The OTNs constantly assessed where to pay most attention as they balanced between the needs of the patient, the team, and the surgery procedure. Conclusion: It is important that every patient is taken into consideration and that ethical principles are held to the highest standards in the OT. A familiar team can facilitate that. The complex skills that operating theatre nurses develop can be added to explain important competencies within the profession.展开更多

Many factors can potentially be associated within an increased amount of errors, leading to adverse events. Nurses, nurse managers, and other leaders all play important roles in establishing patient safety. Aim: This study aimed to obtain a deeper understanding of leaders’ and nurses’ main concerns in establishing patient safety in Swedish intensive care units. Method: A grounded theory methodology was used. Data from 15 interviews with leaders and nurses involved in critical care in Sweden were collected, analysed and constant compared. Findings: The main concern in establishing patient safety was promoting quality of care, work engagement, and staffs well-being in strained ICUs. The core category building trust explained how the leaders’ and nurses’ strove for quality of care and wished a healthy, safe work environment. This is further explained in the categories “Being an accessible and able leader”, “Creating knowledge and understanding”, and “Establishing collaborative practice”. Conclusion: Establishing patient safety in the ICU requires that staffs enjoy going to work, have good work relations, are committed and want to stay at the unit. A healthy, salutogenetic unit with a work environment marked by trust provides a better opportunity to establish patient safety, and various leaders have potential to achieve this.展开更多

This study examined the effect of just one hour of grounding on blood viscosity while subjects participated in gentle yoga exercises designed to initiate minor inflammation. Design: In this double blind model, twenty-eight (28) subjects met at the Bowerman Sports Medicine Clinic on the campus of the University of Oregon and were grounded to the earth via contact with a grounded yoga mat or were sham-grounded. Ten yoga exercises were repeated five times over a one-hour period. Blood was taken pre and post exercise and analyzed for blood viscosity using a scanning capillary viscometer. Results: Subjects connected to the earth significantly reduced their post exercise systolic blood viscosity (p = 0.03) and diastolic blood viscosity (p = 0.03). Conclusion: Grounding has the ability to affect exercise induced inflammation, thereby reducing blood viscosity.展开更多

As real-world applications frequently encounter a multitude of unforeseen events, certain researchers have introduced cross-domain and in-domain event extraction, while grounded situation recognition primarily explores in-domain scenarios. Therefore, in this paper, we propose cross-domain grounded situation recognition and establish a new benchmark SWiG-XD. In this more challenging setting, we deepen the connection between the two tasks based on their underlying unity in two different modalities and explore how to transfer the generalization ability from text to images. Firstly, we utilize ChatGPT to automatically generate textual data, which can be divided into two categories. One category is directly matched with images, establishing a direct connection with the images. The other category encompasses all event types and possesses greater generalization. Then we employ a unified model framework to establish the association between textual concepts and local image features and achieve cross-domain generalization transfer across modalities through modality-shared prompts and self-attention mechanism. Furthermore, we incorporate textual data with higher generalization to further assist in improving generalization on images. The experimental results on the newly constructed benchmark demonstrate the effectiveness of our method.展开更多

文摘This paper aims to explain the construction of the autonomous subject from Foucault's ethical perspective for the qualitative analysis of interprofessional relationships,patient-professional relationships,and moral ethics critique.Foucault tried to break loose from the self,which is merely the result of a biopol-itical subjectivation and constituted an interpersonal level.From this,different elements involved in the decision-making capacity of patients in a clinical setting were analysed.Firstly,the context in which decision-making occurs has been explained,distinguishing between traditional practices involved in self-care and the more modern conceptions that make certain possible transformations.Secondly,an attempt is made to explain the formation of the medicalisation of society using the transformations of what Foucault called"techniques of the self".Finally,the ethical framework for a subject's"self-creation",insisting more on the exercises of self-subjectivation,reinforcing the ethics of the self by itself,the"care of the self",has been explained.The role of the patient is understood as an autonomous subject to the extent that the clinical institution and the professionals involved comprehend how the patient’s autonomy in the clinical environment is constituted.All these elements could generate grounded theory on the qualitative methodology of this phenomenon.The current ethical model based on universal principles is not useful to provide a capacity for patients decision-making,relegating to the background their opinions and beliefs.Consequently,a new ethical perspective emerges that aims to return the patient to the fundamental axis of attention.

文摘Exploring the mechanism for the formation of consumer purchase intentions of geographical indication agricultural products in the context of live-streaming sales can provide an important reference for brand marketing of geographical indication agricultural products.In this study,in-depth interviews were conducted with consumers of geographical indication agricultural products.Based on grounded theory,open coding,axial coding and selective coding were performed for interview text.Finally,21 concepts,7 subcategories and 3 main categories were obtained,and a model of the formation mechanism of the purchase intention of geographical indication agricultural products under the background of live-streaming sales was constructed,that is,"consumer cognition-consumer attitude-consumer behavior".Among them,consumer cognition includes two dimensions:the type of geographical indication agricultural products and the live-streaming appeal strategy,i.e.,the personal cognition of consumer and the promotion of live-streaming host's strategy.Consumer attitude is value perception of consumers,mainly including two dimensions of functional value and emotional value.Consumer behavior is the consumer's willingness to buy.It has been concluded that the types of geographical indication agricultural products interact with the live-streaming appeal strategies.Through the intermediary of consumers'value perception,consumers'purchase intention is generated.Among them,resource-oriented geographical indication agricultural products adopt rational live-streaming appeal strategies,which can enhance the consumer's perception of functional value,thereby promoting their purchase intention;and cultural and creative geographical indication agricultural products brands adopt perceptual live-streaming appeal strategies,which can enhance the emotional value perception of consumers,thereby promoting their purchase intention.
文摘Objective:To elucidate theoretically the safety and identity of mothers receiving egg and the process of becoming a mother.Methods:This study was conducted during 7 months from July 2018 to January 2019 by using a grounded theory approach.Infertile women at the gestational age who received oocyte were selected with purposive sampling method and then entered the study using theoretical sampling.Mothers who had not decided definitely to participate and had not started the treatment course yet were excluded from the study.The participating mothers were 28-44 years old with a mean age of(37.00±2.49)years.A total of 30 interviews were performed.Data were collected by unstructured deep interviews and field notes.The interview duration ranged between 19 to 74 min with a mean time of 40 min and they were performed individually.Results:Data analysis showed that"feeling of insecurity in personal and familial identity"formed in the context of"exposure to socio-cultural constraints"was the main problem of mothers receiving donated oocyte.This led to a set of coping strategies as"gradual acceptance","attempts to maintain the marital life","sensitivity in selecting donor","sensitivity in fetal care","seeking information and consultation","challenging the internal restlessness",and"treatment follow-up",all indicating the concept of"protection of personal and familial identity"as the core variable.Conclusions:The challenge faced by Iranian mothers receiving donated oocyte in the constrained sociocultural context forms a multilateral and all-inclusive insecurity.
文摘In neutral point indirectly grounded systems, phase-to-ground fault is putting new demands on fault diagnosis technology. Information fusion is applied to detect the phase-to-ground fault, which integrates several sources of information, including line current, line voltage, zero sequence current and voltage, and quintic harmonic wave component. This method is testified through the simulation of Matlab. Simulation results show that the precision and reliability of the detection has been greatly increased.
文摘This paper describes the research carried out in partial fulfilment of the degree of doctor of education. The study was qualitative in nature with a phenomenological interpretive paradigm dominating the philosophical approach. The research methods adopted combined life story and grounded theory. As far as the author has been able to determine there are very few, if any studies which have applied this approach specifically to this area of research which investigated the influence life history has on attitude to lifelong learning. Twenty five respondents were interviewed in face-to-face informal interviews. The main aim was to elicit the respondent＇s subjective interpretation of the interaction between school, family, work, and learning within their lives. The researcher was then able to identify when they occurred and what or who made them particularly meaningful. This paper describes how initial decisions were made regarding the substantive area for the research. Sampling technique and method for collecting the data is discussed and a worked example is given of how the data was analysed. It is intended that this paper will give an insight into the challenge of combining these two much debated methods of research. The empirical data lead to some interesting findings which educators and policy makers will find helpful in order to strengthen the school, college, and workplace interface.
文摘Introduction: Intraoperative care includes a unique knowledge of how to perform a safe and effective surgery procedure. Surgery performed under regional or local anaesthesia allows the patient to remain conscious during the procedure and is rather common in Swedish healthcare today. Aim: The aim was to obtain a deeper understanding of the main concerns of operating theatre nurses (OTN) when caring for conscious patients during the intraoperative phase. Methods: Interviews were conducted with 23 OTNs from five different hospitals in Sweden and analysed according to grounded theory. Findings: The main concern among the OTNs was to take the patient in consideration. The core category “achieve and maintain ethical treatment of patients” in the operating theatre (OT) was a strategy used throughout the intraoperative process. Ethical treatment was described as moral behaviour at different levels and included the team’s behaviour, respectful and individualised patientcare, and the working-morale of the professionals. Being vigilant and being flexible were the categories related to the core category. The OTNs constantly assessed where to pay most attention as they balanced between the needs of the patient, the team, and the surgery procedure. Conclusion: It is important that every patient is taken into consideration and that ethical principles are held to the highest standards in the OT. A familiar team can facilitate that. The complex skills that operating theatre nurses develop can be added to explain important competencies within the profession.
文摘Background: The modern intensive care unit (ICU) is a complex and high-risk environment, and even small adverse events and changes may deteriorate the patient’s conditions and eventually cause harm. Many factors can potentially be associated within an increased amount of errors, leading to adverse events. Nurses, nurse managers, and other leaders all play important roles in establishing patient safety. Aim: This study aimed to obtain a deeper understanding of leaders’ and nurses’ main concerns in establishing patient safety in Swedish intensive care units. Method: A grounded theory methodology was used. Data from 15 interviews with leaders and nurses involved in critical care in Sweden were collected, analysed and constant compared. Findings: The main concern in establishing patient safety was promoting quality of care, work engagement, and staffs well-being in strained ICUs. The core category building trust explained how the leaders’ and nurses’ strove for quality of care and wished a healthy, safe work environment. This is further explained in the categories “Being an accessible and able leader”, “Creating knowledge and understanding”, and “Establishing collaborative practice”. Conclusion: Establishing patient safety in the ICU requires that staffs enjoy going to work, have good work relations, are committed and want to stay at the unit. A healthy, salutogenetic unit with a work environment marked by trust provides a better opportunity to establish patient safety, and various leaders have potential to achieve this.
文摘Objective: Research continues to show that being connected to the earth can increase the potential of the body to scavenge free radicals. This study examined the effect of just one hour of grounding on blood viscosity while subjects participated in gentle yoga exercises designed to initiate minor inflammation. Design: In this double blind model, twenty-eight (28) subjects met at the Bowerman Sports Medicine Clinic on the campus of the University of Oregon and were grounded to the earth via contact with a grounded yoga mat or were sham-grounded. Ten yoga exercises were repeated five times over a one-hour period. Blood was taken pre and post exercise and analyzed for blood viscosity using a scanning capillary viscometer. Results: Subjects connected to the earth significantly reduced their post exercise systolic blood viscosity (p = 0.03) and diastolic blood viscosity (p = 0.03). Conclusion: Grounding has the ability to affect exercise induced inflammation, thereby reducing blood viscosity.

文摘Event extraction extracts event frames from text, while grounded situation recognition detects events in images. As real-world applications frequently encounter a multitude of unforeseen events, certain researchers have introduced cross-domain and in-domain event extraction, while grounded situation recognition primarily explores in-domain scenarios. Therefore, in this paper, we propose cross-domain grounded situation recognition and establish a new benchmark SWiG-XD. In this more challenging setting, we deepen the connection between the two tasks based on their underlying unity in two different modalities and explore how to transfer the generalization ability from text to images. Firstly, we utilize ChatGPT to automatically generate textual data, which can be divided into two categories. One category is directly matched with images, establishing a direct connection with the images. The other category encompasses all event types and possesses greater generalization. Then we employ a unified model framework to establish the association between textual concepts and local image features and achieve cross-domain generalization transfer across modalities through modality-shared prompts and self-attention mechanism. Furthermore, we incorporate textual data with higher generalization to further assist in improving generalization on images. The experimental results on the newly constructed benchmark demonstrate the effectiveness of our method.
