Transitional words make any piece of writing flow logically. If properly applied, they give writing cohesion and coherence. The use of proper transitions may be difficult for non-native speakers, particularly for second and foreign language learners. This study examines how frequently students use transitional phrases in their paragraphs. Thirty-six paragraphs written by students of the Department of English-College of Education at Salahaddin University in a writing course serve as the sample of the study. Knowing how frequently transitional words appear in student-written paragraphs is the main goal of the study. Depending on the research goal, the following questions are addressed by this study: How often do students use transitional words? What kinds of transitions do they typically use? The study can help teachers guide their students toward writing more effectively by suggesting appropriate transitions. The study uses quantitative content analysis to determine the frequency of transition words in paragraphs written by first-year students. Using JASP software that recognized and recorded the frequency of transition words, the paragraphs were examined. The outcomes reveal that students employ a range of transitional words, with “and” being the most popular transition. The results imply that students know how crucial transition words are for linking ideas in their writing. To learn more about how transition words and expressions affect the general coherence and clarity of students’ writing, more research is required

The purpose of this study was to examine the kinetics of the walk-to-run transition (WRT) and run-to-walk transition (RWT), when accelerating or decelerating across transition speed (a = 0.17 m·s−2). Nine women performed gait transitions on a 50-m-long walkway. Vertical ground reaction forces (GRFs) and the center of pressure (COP) were examined in the range from 3 steps before to 3 steps after transition in order to identify the possible occurrence of a transition process, in order to facilitate the actual realization of transition. The actual transition is realized in one step, during WRT and RWT. This transition step was characterized by an outlying vertical GRF and COP trajectory (deviating from walking and running). Despite this clear discontinuity, a transitional adaptation period (process) appeared in both transitions. In the WRT, transition was prepared and kinetic adaptations were found in the last step before transition. The RWT was pre- and “post”-pared and only completed during the first walking step after transition. Thus, the WRT and RWT are two distinct phenomena, with different kinetics.

Although Eurocentric scholars theorize the world in terms of Western evolutionary progress rather than de-evolutionary retrogression, this paper takes a different perspective. Forced to transition away from their tangible and intangible heritages, from their families and marriages, cultures, societies, polities, and economies in ways that legitimized imperial claims to res nullius (unowned resources) and terra nullius (empty land), some indigenous people wittingly and unwittingly increasingly devolved their heritages to the colonialists that benefited from the African transitions. The point here is that unlike “Bushmen” and those that practiced transhumance, contemporary Africans are forced to transition, to change and to transform away from owning and controlling their tangible and intangible resources, including land, culture, laws, religions, polities, economies, livestock, families, marriages, and so on. Whereas “Bushmen” and transhumance migrated and transitioned while retaining ownership and control over their land, forests, livestock, and so on, contemporary Africans are forced to transition in ways that divorce them from their families, marriages, cultures, religions, polities, and from ownership of their material resources. Because Eurocentric forms of transition put African institutions and resources on the chopping boards, we argue that this kind of transition is cannibalistic. Made to believe that transition is easier to accomplish without the supposed burden of repossessing ownership and control over one’s resources, Africans are witnessed as disinherited and wandering around the world arguably in ways that even precolonial “Bushmen” and transhumance pastoralists would not envy. There is no justice in “transitional justice” that transitions indigenous people from their heritages.

Background Transition to home after hospitalization involves the potential risk of adverse patient events, such as knowledge deficits related to self-care, medication errors, and readmissions. Despite broad organizational efforts to provide better care transitions for patients, there are challenges in implementing interventions that effectively improve care transition outcomes, as evidenced by readmission rates. Collaborative efforts that require health care professionals, patients, and caregivers to work together are necessary to identify gaps associated with transitions of care and generate effective transitional care interventions. Objective This study aims to understand the usefulness of participatory design approaches in identifying the design implications of transition of care interventions in health care settings. Through a series of participatory design workshops, we have brought stakeholders of the health care system together. With a shared understanding of care transition and patient experience, we have provided participants with opportunities to generate possible design implications for care transitions. Methods We selected field observations in clinical settings and participatory design workshops to develop transitional care interventions that serve each hospital’s unique situation and context. Patient journey maps were created and functioned as tools for creating a shared understanding of the discharge process across different stakeholders in the health care environment. The intervention sustainability was also assessed. By applying thematic analysis methods, we analyzed the problem statements and proposed interventions collected from participatory design workshops. The findings showed patterns of major discussion during the workshop. Results On the basis of the workshop results, we formalized the transition of care model—the socioeconomic, active engagement, follow-up, education, discharge readiness tool, and consistency (Integrated Michigan Patient-centered Alliance in Care Transitions transition of care model)—which other organizations can apply to improve patient experiences in care transition. This model highlights the most significant themes that should necessarily be considered to improve the transition of care. Conclusions Our study presents the benefits of the participatory design approach in defining the challenges associated with transitions of care related to patient discharge and generating sustainable interventions to improve care transitions.

Three guardrail-to-bridge rail transitions were developed and subjected to full-scale crash tests. The transitions were ( a) a nested W-beam with W-beam rub rail that transitioned from a W-beam guardrail to a vertical concrete parapet bridge rail, ( b) a nested thrie-beam that transitioned from a W-beam guardrail to a tubular steel bridge rail, and ( c) a tubular steel transition that transitioned from a weak-post box-beam guardrail to a tubular steel bridge rail. The nested W-beam and the tubular steel transitions were tested and met NCHRP Report 350 Test Level (TL)-3 requirements. The nested thrie-beam transition was tested and met TL-4 requirements.

Testo completoAbstract (sommario):
There is growing interest in how athletes’ physical activity participation may be impacted when they transition out of competitive sport; however, few studies have examined the process of physical activity transitions in collegiate student-athletes using a qualitative approach. The purpose of our study was to explore student-athletes’ perceptions of, and experiences with, physical activity in the transition out of collegiate sport. Our analysis of transcripts from 13 focus groups conducted with current and former student-athletes (n = 59) suggests that student-athletes experienced a journey from control to liberation as they transitioned into their postcompetitive lives. In this exciting yet challenging transitional journey, participants were faced with navigating newfound autonomy over their physical activity outside of the controlled environment of collegiate sports and were considering the value and meaning of physical activity within a health promoting context. We offer practical recommendations from these findings to support student-athletes in this transition.

Panama’s transition from military dictatorship to civilian government is considered in terms of stages of the democratization process. During the decline of the dictatorship (stage one), four transitions -- two electoral, and two negotiations for an elite settlement -- were attempted but failed. Consequently, Panama did not experience a normal second, transitional stage. Instead Panama’s transition was abrupt and unexpected: civilian government was installed during a U.S. invasion. Challenges and progress in consolidating democracy (the third stage) are assessed with special attention to restoration of civilian governance, democratic habits and values, and demilitarization-- a central priority of the new regime.

Increasing numbers of gender-nonconforming children are socially transitioning—changing pronouns to live as their identified genders. We studied a cohort of gender-nonconforming children ( n = 85) and contacted them again approximately 2 years later. When recontacted, 36 of the children had socially transitioned. We found that stronger cross-sex identification and preferences expressed by gender-nonconforming children at initial testing predicted whether they later socially transitioned. We then compared the gender-nonconforming children with groups of transitioned transgender children ( n = 84) and gender-conforming controls ( n = 85). Children from our longitudinal cohort who would later transition were highly similar to transgender children (children who had already socially transitioned) and to control children of the gender to which they would eventually transition. Gender-nonconforming children who would not go on to transition were different from these groups. These results suggest that (a) social transitions may be predictable from gender identification and preferences and (b) gender identification and preferences may not meaningfully differ before and after social transitions.

Abstract In order to understand transitional spaces I would like to create an in-depth study that includeshow they evolve, reviews their evolution and hierarchy, and analyses their role and importance. There are several types of transition spaces that can be distinguished, in my study I examine more specifically the transitions between the natural and built environment. In my study I wanted to put emphasis on the relationship between man and nature, furthermore the relationship between nature and architecture, this knowledge is necessary to understand these spaces.

AbstractPhase transitions connect different states of matter and are often concomitant with the spontaneous breaking of symmetries. An important category of phase transitions is mobility transitions, among which is the well known Anderson localization1, where increasing the randomness induces a metal–insulator transition. The introduction of topology in condensed-matter physics2–4 lead to the discovery of topological phase transitions and materials as topological insulators5. Phase transitions in the symmetry of non-Hermitian systems describe the transition to on-average conserved energy6 and new topological phases7–9. Bulk conductivity, topology and non-Hermitian symmetry breaking seemingly emerge from different physics and, thus, may appear as separable phenomena. However, in non-Hermitian quasicrystals, such transitions can be mutually interlinked by forming a triple phase transition10. Here we report the experimental observation of a triple phase transition, where changing a single parameter simultaneously gives rise to a localization (metal–insulator), a topological and parity–time symmetry-breaking (energy) phase transition. The physics is manifested in a temporally driven (Floquet) dissipative quasicrystal. We implement our ideas via photonic quantum walks in coupled optical fibre loops11. Our study highlights the intertwinement of topology, symmetry breaking and mobility phase transitions in non-Hermitian quasicrystalline synthetic matter. Our results may be applied in phase-change devices, in which the bulk and edge transport and the energy or particle exchange with the environment can be predicted and controlled.

Background and Objectives The scope of interventions offered to infants with trisomy 13 (T13) or trisomy 18 (T18) is increasing. We describe the spectrum of care provided, highlighting transitions in care for individual patients. Patients and Methods This is a single-center, retrospective cohort of infants with T13 or T18 born between 2004 and 2015. Initial care was classified as comfort care or intervention using prenatal counseling notes. Transitions in care were identified in the medical record. Results In this study, 25 infants were divided into two groups based on their care: neonates who experienced no transition in care and neonates who experienced at least one transition. Eleven neonates experienced no transition in care with 10 receiving comfort care. Fourteen neonates experienced at least one transition: three transitioned from comfort care to intervention and 11 from intervention to comfort care. The three initially provided comfort care were discharged home with hospice and readmitted. Among the 11 cases who transitioned from intervention to comfort care, 9 transitioned during the birth hospitalization, 6 had no prenatal suspicion for T13 or T18, and 5 experienced elective withdrawal of intensive care. Conclusion The spectrum of care for infants with T13 or T18 illustrates the need for individualized counseling that is on-going, goal directed, collaborative, and responsive.

AbstractAustria's post-World War II transition from two consecutive, abusive regimes (the Austro-fascist and the Nazi regime) to a functioning democracy has not yet been thoroughly assessed through the lens of transitional justice. An evaluation of what could now be dubbed transitional-justice measures shows that Austria was reluctant in accepting its collective responsibility vis-à-vis the victims of World War II. Another defining factor of Austria's transition is that it never encouraged the surviving victims of the Nazi regime to return. An appraisal of Austria's transition in light of the two final ends of transitional justice, namely democracy and reconciliation, culminates in two conclusions: first, Austria attained the goal of democracy but failed with reconciliation; second, the current model of transitional justice is ill-equipped to assess the non-linear course of long-past transitions.

Abstract During their life course, many older adults encounter a transition between care settings, for example, a permanent move into long-term residential care. This care transition is a complex and often fragmented process, which is associated with an increased risk of negative health outcomes, rehospitalisation, and even mortality. Therefore, care transitions should be avoided where possible and the process for necessary transitions should be optimised to ensure continuity of care. Transitional care is therefore a key research topic. The TRANS-SENIOR European Joint Doctorate (EJD) network builds capacity for tackling a major challenge facing European long-term care systems: the need to improve care for an increasing number of care-dependent older adults by avoiding unnecessary transitions and optimising necessary care transitions. During this symposium, four presenters from the Netherlands and Switzerland will present different aspects of transitions into long-term residential care. The first speaker presents the results of a co-creation approach in developing an intervention aimed at preventing unnecessary care transitions. The second speaker presents an overview of interventions aiming to improve a transition from home to a nursing home, highlighting the clear mismatch between theory and practice. The third speaker presents the impact of the COVID-19 pandemic on transitions into long-term residential care using an ethnographic study in a long-term residential care facility in Switzerland. The final speaker discusses the results of a recent Delphi study on key factors influencing implementing innovations in transitional care. The discussant will relate previous findings on transitional care with a U.S. perspective.

Testo completoAbstract (sommario):
This article examines the precarious transition from school to work, considers its relation to young people's identity formation in late modern Japan, and rethinks the theory of identity formation in late modernity. Although Japan's transition system had been efficient and stable over many years, since the late 1990s this has been replaced by an increasing precariousness. The Japanese government has responded with a Career Education promotion policy to foster young people's work aspirations and attitudes in the form of an employability enhancement policy. This policy discourse coincides with a late modernist theory (as put forward by Giddens and Cote & Levine) that emphasises the importance of personal agency for young people's transitions. However, in our longitudinal qualitative study, we found that the ‘transitional communities and networks' that young people encounter in their transition from school to work have an important supportive role to play. These transitional communities are important in young people's transitions from the school/college community to the workplace community. Those who had a strong sense of agency but no helpful community experienced serious depression and did not make a successful transition into work. Our case studies support Erikson's argument that community (communality) is indispensable for young people's identity formation. We conclude that both community and agency are important for successful transition in late modernity.

Testo completoAbstract (sommario):
Although research on land use transitions has gradually received widespread attention since its introduction to China at the beginning of the new millennium, the lack of a clear portrayal of the transitional characteristics and pathways of land use at the theoretical level has prevented this research from providing adequate support for the regulation and management of rural land use activities. This study aims to bridge this research gap from a functional perspective, since the transition of land system functions—also known as land use functions—heralds the completion of a regional land use transition. The methods employed included a literature review and theoretical analysis. The results show the following: (1) the relationships between land use morphology, land use multifunctionality, and land use functions transition (LUFT) were identified; (2) the connotation of the multifunctional agriculture transition theory was analyzed, and the applicability and limitations of drawing on the theory for researching the transition of land use functions in rural China elucidated; (3) a method for characterizing LUFT is proposed from the “state” and “quality”; (4) a theoretical framework for the LUFT was constructed and anchored in transition theory; and (5) it was summarized that there are three transitional pathways: weak-strong, strong-weak, and dynamic balance. In conclusion, while theories originating from the West can provide references for Chinese research, the significant difference between their socio-economic backgrounds necessitates reconstructing these theories in the light of the actual situation in rural China. The theoretical construction of land use transitions from a functional perspective can more clearly delineate the process, the trend, and the characteristics of the transitions of rural land use, thus offering valuable insights for the regulation and management of land use.

Purpose This paper provides an overview of transitions across forensic child and adolescent mental health services in England and Wales. The purpose of this paper is to delineate the national secure services system for young people in contact with the youth justice system. Design/methodology/approach This paper reviews findings from the existing literature of transitions across forensic child and adolescent mental health services, drawing attention to present facilitators and barriers to optimal transition. The authors examine the infrastructure of current services and highlight gaps between child and adult service continuity and evaluate the impact of poor transitions on young offenders’ mental health and wellbeing. Findings Young offenders experience a broad range of difficulties, from the multiple interfaces with the legal system, untreated mental health problems, and poor transition to adult services. Barriers such as long waiting lists, lack of coordination between services and lack of transition preparation impede significantly smooth transitions. Research limitations/implications The authors need to develop, test and evaluate models of transitional care that improve mental health and wellbeing of this group. Practical implications Mapping young offenders’ care pathway will help to understand their needs and also to impact current policy and practice. Key workers in forensic services should facilitate the transition process by developing sustainable relationships with the young person and creating a safe clinical environment. Originality/value Transition of care from forensic child and adolescent mental health services is a neglected area. This paper attempts to highlight the nature and magnitude of the problems at the transition interface in a forensic context.

Testo completoAbstract (sommario):
This paper uses Danish population-based administrative registers to study contemporary school-to-work transitions among young adults who experience long-term NEET episodes between age 16 and 20. By applying sequence analysis and clustering, this paper identifies five distinct transition patterns. Using this typology as the outcome variable in multinomial regression the paper offers insight into how experiences and circumstances, developing until age 16, can affect the subsequently unfolding transition process. Finally, the paper looks ahead and describes whether transitional difficulty accumulates into early adulthood. While one transition pattern stands out as more stable and less worrying, three of the remaining four demonstrate how transitional difficulty between age 16 and 20 develops as precarious patterns of attachment to well-established systems within the Danish welfare state. It is further established that various childhood risk factors significantly increase the odds of experiencing precarious transition patterns. Finally, the analyses demonstrate how instability and risk during childhood and school-to-work transition extend into early adulthood for a large part of the study population.

Testo completoAbstract (sommario):
Cardiovascular diseases are the leading cause of death globally and there is an unmet need for effective, safer blood-contacting devices, including valves, stents and artificial hearts. In these, recirculation regions promote thrombosis, triggering mechanical failure, neurological dysfunction and infarctions. Transitional flow over a backward facing step is an idealised model of these flow conditions; the aim was to understand the impact of non-Newtonian blood rheology on modelling this flow. Flow simulations of shear-thinning and Newtonian fluids were compared for Reynolds numbers ( R e ) covering the comprehensive range of laminar, transitional and turbulent flow for the first time. Both unsteady Reynolds Averaged Navier–Stokes ( k − ω SST) and Smagorinsky Large Eddy Simulations (LES) were assessed; only LES correctly predicted trends in the recirculation zone length for all R e . Turbulent-transition was assessed by several criteria, revealing a complex picture. Instantaneous turbulent parameters, such as velocity, indicated delayed transition: R e = 1600 versus R e = 2000, for Newtonian and shear-thinning transitions, respectively. Conversely, when using a Re defined on spatially averaged viscosity, the shear-thinning model transitioned below the Newtonian. However, recirculation zone length, a mean flow parameter, did not indicate any difference in the transitional Re between the two. This work shows a shear-thinning rheology can explain the delayed transition for whole blood seen in published experimental data, but this delay is not the full story. The results show that, to accurately model transitional blood flow, and so enable the design of advanced cardiovascular devices, it is essential to incorporate the shear-thinning rheology, and to explicitly model the turbulent eddies.

While the majority of attention and the literature has focused on transitional models out of the acute care setting, transitions from the post-acute setting—especially from the skilled nursing facility (SNF)—are not well understood. What are the ‘best practices’, or thoughtful considerations, for a successful transition back to home and the community? Facilitation of a smooth and seamless transition relies on the abilities of the SNF and primary care teams, as well as community agencies, to coordinate care in a patient-centered manner together. This article will focus on this specific transition within the healthcare continuum.

Testo completoAbstract (sommario):
Patients in the intensive care unit (ICU) increasingly are expected to eventually return home after acute hospital care. Yet transitional care for ICU patients and their families is often delayed until the patient is about to be transferred to another location or level of care. Transitions theory is a middle-range nursing theory that aims to provide guidance for safe and effective nursing care and research while an individual experiences a transition. Intensive care unit nurses are well positioned to provide ICU transitional care planning early. This article applies the transitions theory as a theoretical model to guide the study of the transition to home after acute hospital care for ICU patients and their families. This theory application can help ICU nurses provide holistic patient- and family-centered transitional care to achieve optimal outcomes by addressing the predischarge and postdischarge needs of patients and families.

This paper traces the transition from planned command socialism to market capitalism and the accompanying complex non-linear dynamics involved. Long wave chaotic hysteretic investment cycles emerge under socialism leading to crisis and breakdown. Macroeconomic collapse occurs with bifurcations of coordination structures during transition. During recovery, transitional cobweb labor market dynamics exhibit chaos, fractal basin boundaries between coexisting non-chaotic attractors, discontinuous phase transitions, strange attractors, and cascades of infinitely many period-doubling bifurcations.

Testo completoAbstract (sommario):
The K-type and H-type transitions of a natural convection boundary layer of a fluid of Prandtl number 7 adjacent to an isothermally heated vertical surface are investigated by means of three-dimensional direct numerical simulation (DNS). These two types of transitions refer to different flow features at the transitional stage from laminar to turbulence caused by two different types of perturbations. To excite the K-type transition, superimposed Tollmien–Schlichting (TS) and oblique waves of the same frequency are introduced into the boundary layer. It is found that a three-layer longitudinal vortex structure is present in the boundary layer undergoing the K-type transition. The typical aligned $\wedge$-shaped vortices characterizing the K-type transition are observed for the first time in pure natural convection boundary layers. For exciting the H-type transition, superimposed TS and oblique waves of different frequencies, with the frequency of the oblique waves being half of the frequency of the TS waves, are introduced into the boundary layer. Unlike the three-layer longitudinal vortex structure observed in the K-type transition, a double-layer longitudinal vortex structure is observed in the boundary layer undergoing the H-type transition. The successively staggered $\wedge$-shaped vortices characterizing the H-type transition are also observed in the downstream boundary layer. The staggered pattern of $\wedge$-shaped vortices is considered to be caused by temporal modulation of the TS and oblique waves. Interestingly the flow structures of both the K-type and H-type transitions observed in the natural convection boundary layer are qualitatively similar to those observed in Blasius boundary layers. However, an analysis of turbulence energy production suggests that the turbulence energy production by buoyancy rather than Reynolds stresses dominates the K-type and H-type transitions. In contrast, the turbulence energy production by Reynolds stresses is the only factor contributing to the transition in Blasius boundary layers.

Testo completoAbstract (sommario):
AimsTo evaluate current transition service provision from CAMHS to AMHS focusing on information sharing, transition planning and continuity of care. Many young people find service transition from CAMHS to AMHS stressful, sometimes because of there being multiple simultaneous transitions from child centred services to adult oriented models of care. If not handled well, this can lead to drop out from services, repeated assessments, suboptimal treatment and support, and raised likelihood of emergency psychiatric admissions. Longitudinal planning and sensitive management of transition is vital, because of transition being a risk period for young people.MethodsA retrospective case note survey of service users who had transitioned from 1st February 2020 to 31st January to 2022 was undertaken. Fifteen individuals transitioned: 9 females and 6 males. All were White British except for one who was Sudanese and an asylum seeker. Six out of 15 young people had a diagnosis of Autism Spectrum Disorder (ASD) in addition to other diagnoses making transition more difficult, as more agencies were involved requiring multiple meetings prior to transition to adult services. One case of emerging personality disorder, despite our best efforts for smooth transitioning, had already disengaged from CAMHS.ResultsMost individuals transitioned successfully to adult mental health services. Two were transferred to learning disability, and one to early intervention in psychosis services, the diagnoses having been confirmed by the treating psychiatrist near the patient's 18th birthday. One was transferred to a rehabilitation service. Only one referral was declined.The transition pathway is patient centred, and provides clear transition plans to young person, family and carers. In the past 4 months AMHS, because of lack of resources, have not been able to identify a named worker till a few weeks before the patient's 18th birthday, which conflicts with NICE guidelines.ConclusionAn effective transition service was found to include •A designated psychiatrist to facilitate smooth transition of complex cases to AMHS, providing continuity of care, good intra and inter agency working and maximising patient welfare.•CAMHS preparation of young persons for transition commencing six months before their 18th birthday.•Prior researching of best transition destinations.•An overlap period of CAMHS/AMHS joint working.•Identified CAMHS and AMHS transition coordinators.•Patient and family engagement with process.•Mindfulness and awareness of AMHS eligibility criteria.

Testo completoAbstract (sommario):
Electroencephalographic sleep stage transitions and altered first REM sleep period transitions have been identified as biomarkers of type 1 narcolepsy in adults, but not in children. Studies on memory complaints in narcolepsy have not yet investigated sleep-dependent memory consolidation. We aimed to explore stage transitions; more specifically altered REM sleep transition and its relationship with sleep-dependent memory consolidation in children with narcolepsy. Twenty-one children with narcolepsy–cataplexy and twenty-three healthy control children completed overnight polysomnography and sleep-dependent memory consolidation tests. Overnight transition rates (number of transitions per hour), global relative transition frequencies (number of transitions between a stage and all other stages/total number of transitions × 100), overnight transitions to REM sleep (transition from a given stage to REM/total REM transitions × 100), and altered first REM sleep period transitions (transitions from wake or N1 to the first REM period) were computed. Narcoleptic children had a significantly higher overnight transition rate with a higher global relative transition frequencies to wake. A lower sleep-dependent memory consolidation score found in children with narcolepsy was associated with a higher overnight transition frequency. As observed in narcoleptic adults, 90.48% of narcoleptic children exhibited an altered first REM sleep transition. As in adults, the altered sleep stage transition is also present in children with narcolepsy–cataplexy, and a higher transition rate could have an impact on sleep-dependent memory consolidation. These potential biomarkers could help diagnose type 1 narcolepsy in children more quickly; however, further studies with larger cohorts, including of those with type 2 narcolepsy and hypersomnia, are needed.

Transitional care incorporates actions to ensure the coordination and continuity of care between provider settings (ie, hospitals, nursing homes, home health care, patients’ home, and physician offices) occurs to meet the patient’s goals relative to their disease management. The evolution of transitional care over the past decade has facilitated the emergence of several transitional care models. However, there is a dearth of understanding related to the collaboration between nurse transition coaches and home care nurses when implementing transitional care model activities to achieve desired patient outcomes in the home health care setting. This case study describes the enactment of a specific transitional care model’s conceptual framework to derive an in-depth understanding of the collaborations between nurse transition coaches and home health nurses in the unique context of home health care. The case is a specific patient-centered Care Transitions Intervention (CTI) model with 4 embedded subunits: (1) the experiences and actions of the nurse transitions coach, (2) the experiences and actions of the home health nurse, (3) document and artifacts review, and (4) the experiences and observations of key leadership stakeholders involved in transitional care activities in one home health care organization located in Michigan.

Testo completoAbstract (sommario):
Transitional justice is a framework for dealing with past atrocities that are on such a large scale and so horrific that the usual institutions and justice system are unable to adequately address them. Countries in Latin America that transitioned from dictatorship to democracy in the 1980s pursued transitional justice when deciding how to meet the demands of victims and what to do with perpetrators. The interdisciplinary field of transitional justice studies is robust within the social sciences and law. Yet artistic production engages in dialogues with the official and unofficial stories of the dictatorships and their legacies and also contributes to understanding transitions to democracy. This essay examines how visual art in Uruguay engages with transitional justice and memory of the dictatorship (1973–85), taking as a case study the installation Artista de mierda (Artist of Shit, 2019) by Fernando Barrios (b. 1968). Nearly four decades after Uruguay began its democratic transition, the struggle over which narratives would dominate the collective memory of state terror and what society should do about the open wounds of the dictatorship continues to be negotiated. Beyond merely reflecting common discourses about the dictatorship and democracy, Artista de mierda engages with the memory of state violence and reveals how Uruguay’s incomplete transition to democracy and its embrace of neoliberalism exacerbate inequality and create conditions for certain political figures and artists to rise to prominence within their respective fields.

Testo completoAbstract (sommario):
The paper deals with transition to adulthood of young people in Serbia through analysis of findings of the two surveys from 2003 and 2011. The aims are to explore the changes in pace, as well as in transitional trajectories that could indicate their destandardisation and individualisation. Some of the debatable issues related to the transition to adulthood approach are presented in the framework and discussed further in relation to the results of the analysis in the concluding section. The findings indicate that there exists some acceleration in the pace of transition, mainly due to increased financial independence of young people. The trajectories, however, are still standardised, while transition is postponed and prolonged. The comparative analyses of some features of young people?s transitions to adulthood in the Balkans led to the conclusion that an alternative conceptualization is needed.

Testo completoAbstract (sommario):
Sharp changes in state, such as transitions from survival to extinction, are hallmarks of evolutionary dynamics in biological systems. These transitions can be explored using the techniques of statistical physics and the physics of nonlinear and complex systems. For example, a survival-to-extinction transition can be characterized as a non-equilibrium phase transition to an absorbing state. Here, we review the literature on phase transitions in evolutionary dynamics. We discuss directed percolation transitions in cellular automata and evolutionary models, and models that diverge from the directed percolation universality class. We explore in detail an example of an absorbing phase transition in an agent-based model of evolutionary dynamics, including previously unpublished data demonstrating similarity to, but also divergence from, directed percolation, as well as evidence for phase transition behavior at multiple levels of the model system's evolutionary structure. We discuss phase transition models of the error catastrophe in RNA virus dynamics and phase transition models for transition from chemistry to biochemistry, i.e., the origin of life. We conclude with a review of phase transition dynamics in models of natural selection, discuss the possible role of phase transitions in unraveling fundamental unresolved questions regarding multilevel selection and the major evolutionary transitions, and assess the future outlook for phase transitions in the investigation of evolutionary dynamics.

Testo completoAbstract (sommario):
Oral treprostinil has recently been shown to delay disease progression in patients with pulmonary arterial hypertension in a long-term outcomes study. The potential advantages of an oral formulation have resulted in patients transitioning from inhaled to oral treprostinil. The current study reports a retrospective analysis of patients who transitioned from treatment with inhaled to oral treprostinil. A multicenter retrospective chart review was conducted for 29 patients with pulmonary hypertension that transitioned from inhaled to oral treprostinil. Data were collected from inhaled treprostinil initiation and patients were followed until discontinuation of oral treprostinil or the end of the observation period. Persistence was calculated using Kaplan–Meier estimates. Prior to transition to oral treprostinil, patients had received inhaled treprostinil for a median of 643 (IQR: 322–991) days and 52% of patients were New York Heart Association/World Health Organization Functional Class III. For patients that cross-titrated between formulations, the median time to complete the cross titration was 24 (IQR: 1–57) days. At 16- and 24-weeks post-transition, oral treprostinil persistence was 86 and 76%, respectively. Persistence was 59% at 52 weeks post-transition. Clinical stability for the majority of patients at first follow-up post-transition was suggested based on available New York Heart Association/World Health Organization Functional Classification. Transitions from inhaled to oral treprostinil appeared safe and tolerable in the short-term. Additional prospective studies are needed to fully evaluate the safety and efficacy of transitions from inhaled to oral treprostinil.

Introduction : Stroke is a life threatening medical emergency that occurs suddenly and impact greatly in all aspect of an individual’s normal life since the early stage to long term. Various types of transitional care models are using by Health systems to improve care transition among stroke patients. Aims:
This paper aims to explore the existing transitional care models used to improve the quality of care and patient’s outcome among stroke survivors.
Methods: An Integrated review was conducted of empirical literature available in PubMed, Google Scholar, ProQuest, and NepJol by June 20, 2022 to identify studies of hospital to home care transitions of stroke patients with quality of care as the primary outcome.
Results: There are 6 main types of transitional care model which focused on care transition for stroke survivors: 1) Naylor’s Transitional Care Model (TCM), 2) Coleman’s Care Transition Interventions (CTI), 3) Project Re-engineered Discharge (project RED), 4) Better Outcomes by Optimizing Safe Transition (Project Boost), 5) Enhanced Discharge Planning Program and 6) Comprehensive Post- Acute Stroke Services (COMPASS). Although, all models are differing by design, each of the models can provide a framework for managing health conditions from hospital to home settings in collaboration with the client and his/her family. Hence, the transitional care Models are effective in bridging the care gap between hospital to home and improve the quality of health care and patient outcomes among stroke survivors.

Although numerous healthcare organizations have transitioned from one electronic health record (EHR) to another or are currently planning a transition, there are few documented artifacts, such as published studies or operationalizable resources, that offer guidance on such transitions. This panel seeks to begin a conversation about human factors considerations in EHR transitions from a legacy system. Panel members will discuss current literature and research on the topic as well as experiences with and lessons learned from transitions within their organizations. Panel discussion can be expected to identify new research opportunities, needed resources, and guidance for EHR vendors or healthcare facilities in the midst of or preparing for an EHR transition. Panelists will also lay out systemic issues that need to be addressed at the national policy and regulatory level. This topic is relevant not only to full-scale EHR transitions, but also has applicability for significant EHR version changes.

Testo completoAbstract (sommario):
The question of when and why societies have transitioned away from matriliny to other types of kinship systems—and when and why they transition towards matriliny—has a long history in anthropology, one that is heavily engaged with both evolutionary theory and cross-cultural research methods. This article presents tabulations from a new coding of ethnographic documents from the Standard Cross-Cultural Sample (SCCS), tallying claims of transitions in kinship systems both away from and to matriliny using various levels of stringency. We then use our counts as the outcome variables in a set of Bayesian analyses that simultaneously estimate the probability of a transition occurring given societal covariates alongside the conditional probability of detecting a transition given the volume of ethnographic data available to code. Our goal is to estimate the cross-cultural and comparative frequency of transitions away from and to matriliny, as well as to explore potential causes underlying these patterns. We find that transitions away from matriliny have been significantly more common than ‘reverse transitions' to matriliny. Our evidence suggests that both rates may be, in part, an artefact of the colonial and globalizing period during which the data comprising much of the current ethnographic record were recorded. Analyses of the correlates of transitions away from matriliny are consistent with several of the key causal arguments made by anthropologists over the past century, especially with respect to subsistence transition (to pastoralism, intensive agriculture and market economies), social complexity and colonialism, highlighting the importance of ecological factors in such transitions. This article is part of the theme issue ‘The evolution of female-biased kinship in humans and other mammals’.

Democratization from authoritarian rule has been an important focus of scholarly interest in the 1980s. However, no typology of democratic transitions currently exists. This article introduces a typology of transitions from authoritarianism to democracy with four major types: incremental democratization, transition through rupture, transition through protracted revolutionary struggle, and transition through transaction. The remainder of the article discusses the conditions for one type of democratic transition, transition through transaction, in Spain (1975-1978). As the Spanish case suggests, the conditions for this type of transition are quite different from those required for other forms of transition. The summary discussion of the Spanish case is divided into a consideration of the conditions for the initiation of transition through transaction, and an examination of the conditions for the implementation of transition through transaction. Both sections emphasize the crucial role of elite attitudes and skill in transitions through transaction.

Testo completoAbstract (sommario):
Problem: Suboptimal care transitions can lead to re-hospitalizations. Intervention: We developed a 2-week “Transitions of Care Curriculum” to train first-year internal medicine residents to improve their knowledge and skills to deliver optimal transitional care. Our objective was to use reflective writing essays to evaluate the impact of the curriculum on the residents. Methods: The rotation included: Transition of Care Teaching modules, Transition Audit, Transitional Care Site Visits, and Transition of Care Conference. Residents performed the above elements of care transitions during the curriculum and wrote reflective essays about their experiences. These essays were analyzed to assess for the overall impact of the curriculum on the residents. Qualitative analysis of reflective essays was used to evaluate the impact of the curriculum. Of the 20 residents who completed the rotation, 18 reflective essays were available for qualitative analysis. Results: Five major themes identified in the reflective essays for improvement were: discharge planning, patient-centered care, continuity of care, goals of care discussions, and patient safety. The most discussed theme was continuity of care, with following subthemes: fragmentation of the healthcare system, disjointed care to the patients, patient specific factors contributing to lack of continuity of care, lack of primary care provider role as a coordinator of care, and challenges during discharge process. Residents also identified system-based gaps and suggested solutions to overcome these gaps. Conclusions: This experiential learning and use of reflective writing enhanced the residents’ self-identified awareness of gaps in care transitions and prompted them to generate ideas for systems improvement and personal actions to improve their practice during care transitions.

This study examines transitions in marriage by merging the frameworks of the relational turbulence model and the experiencing life transitions model. An online survey presented 208 married individuals with open-ended questions and closed-ended scales that gathered information about a particularly important transition in the respondent’s marriage, the quality of their relationship during the transition, and the strategies used to navigate the transition. Analyses, which focused on 157 participants who reported experiencing a transition in their marriage, revealed 10 categories of transitions, the most frequent of which were sparked by health issues or the death of a loved one. Type of transition demonstrated unique associations with relational uncertainty, interference from a partner, relational turbulence, and transition processing activity. Several significant associations between qualities of relational turbulence, engagement in transition processing activity, and transition valence emerged.

Testo completoAbstract (sommario):
By using complex potentials, some light is shed on the analogy between the singularity problems arising in fluid and fracture mechanics—in particular, those concerning plane irrotational flows around sharp obstacles and plane elasticity in cracked bodies. Applications to two equivalent geometries are shown: a thin plate transversally immersed in a uniform flow and a crack subjected to uniform out-of-plane shearing stress at infinity (Mode III). The matching between the fluid velocity field and the shearing stress field is consistent with the hydrodynamic analogy. Aside from the Reynolds criterion for the natural laminar-to-turbulent transition, a velocity-intensity factor criterion is defined to predict the forced turbulent-to-vortex-shedding fluid-flow transition (forced transitional flow) generated by a transversal plate obstacle. It is interesting to remark that the velocity-intensity factor presents physical dimensions intermediate between those of a velocity and a kinematic viscosity. In addition, it will be demonstrated that size affects the occurrence of natural-to-forced transitional phenomena in fluids, in a strict analogy to the scale-dependent ductile-to-brittle failure transitions in solids.

Testo completoAbstract (sommario):
Areas of environmental transition, where ecological communities coincide, are sometimes termed ecotones. These regions often correspond with sharp environmental gradients. Ecotones occur at multiple spatial scales, ranging from transitions between biomes to local small-scale transitions. In recent years ecotones have received increasing scientific attention after being neglected for years, as studies historically often focused on distinct communities. However, it is still debatable whether these transitional regions are speciation and biodiversity hotspots that deserve special conservation interest or are actually areas that hold marginal populations that depend on other parts of the range for the maintenance of their biodiversity and therefore should not deserve primary investment. This paper discusses some of the recent advancements in our understanding of the role of ecotones in ecology, evolution, and conservation.

Testo completoAbstract (sommario):
Background: In 2014, Dudley Group of Hospitals (DGH) underwent an organizational change that necessitated closure of their Home Parenteral Nutrition (HPN) service. University Hospitals Birmingham NHS Foundation Trust (UHBFT) transitioned 50 patients from DGH into their HPN service. The transition model included communication with patients, communication between centers (development of an HPN Patient Passport), and rapid follow-up on transition ensuring clinical care continued uninterrupted. Aim: Evaluate patient experience and their level of satisfaction with our HPN transition model. Method: A 19-point, mixed mode paper-based questionnaire was developed. Questionnaires were posted to 42 surviving patients still receiving HPN. Results: Response rate: 67%. Communication with patients: The transition was discussed with them, and they had appropriate contact details during the process—94%. Patients informed of patient transition meetings—97%. Attendance at meetings: DGH 89%, UHBFT 55%. Ongoing care at UHBFT: 86% very satisfied and 11% satisfied. Overall rating of the transition process: 79% very satisfied and 14% satisfied. Friends and Family Test: 82% “extremely likely” and 18% “likely” to recommend our services. Conclusion: The transition model used was successful, with the majority of patients “very satisfied” with how the transition was managed and their ongoing care. Effective communication with patients and between the 2 centers was the key to success. To our knowledge, this is the first report of transition of care for HPN patients. It is proposed that this model may be used by other centers to plan for future HPN service transitions where necessary.

Testo completoAbstract (sommario):
In a previous study, we found that participants modified how they transitioned onto and off of ramp configurations depending upon the incline. While the transition strategies were originally attributed to ramp angles, it is possible that the plateau influenced the strategies since the final surface height also differed. Ultimately, for the current study, we hypothesized that an individual’s transition strategies would have significant main effects for ramp angle, but not plateau height. Twelve healthy, young adults transitioned onto 3 distinct ramp configurations, a 2.4-m ramp angled at 12.5° ending at a plateau height of 53 cm, a 1.2-m ramp angled at 23.5° ending at a plateau height of 53 cm, and a 2.4-m ramp angled at 23.5° ending at a plateau height of 99.5 cm. Kinematics, kinetics, and muscle activity were measured during the stance phase before contacting the ramp. In support of our hypothesis, impact peak, active peak, and all of the muscle activity variables had a significant main effect for ramp angle, with greater vertical force peaks and muscle activity on steeper ramp transitions. These findings support our previous interpretation that individuals use estimations of ramp angle, not plateau height, to determine their transition strategies.

Testo completoAbstract (sommario):
Background Stroke patients with dysphagia and family caregivers will experience multiple transitions during the whole process of the disease and various nursing needs will be generated. There is a lack of knowledge about their experiences at different transition stages. Thus, we aimed to explore the transition experiences of patients with post stroke dysphagia and family caregivers from admission to discharge home. Methods A semi-structured interview based on Meleis’s transition theory was used during hospitalization and telephone follow-up interviews were conducted in the first, third, and sixth month after the diagnosis of dysphagia. Interview transcripts were analyzed using the conventional content analysis method. Results A total of 17 participants enrolled in the first face-to-face interview, 16 participants took part in the first month’s telephone follow-up interview, 14 participants in the third month, and 12 participants in the sixth month. The transition experiences of patients with post stroke dysphagia and family caregivers could be summarized into three themes: (1)transition from onset to admission; (2)transition from discharge to other rehabilitation institutions; and (3)transition from discharge to home. Each theme had identified interrelated subthemes. Conclusions The experiences of patients with post stroke dysphagia and family caregivers during transition are a dynamic process with enormous challenges in each phase. Collaboration with health care professionals, follow-up support after discharge, and available community and social support should be integrated into transitional nursing to help patients facilitate their transition.

Testo completoAbstract (sommario):
When using labelled transition systems to model languages like CCS or TCSP, one specifies transitions by a set of structural rules. We consider labelling transitions with their proofs – in the given system of rules – instead of simple actions. Then the label of a transition identifies uniquely that transition, and one may use this information to define a concurrency relation on (proved) transitions, and a notion of residual of a (proved) transition by a concurrent one. We apply Berry and Lévy’s notion of equivalence by permutations to sequences of proved transitions for CCS to obtain a partial order semantics for this language.

Purpose There is substantial evidence that young people moving from child and adolescent mental health services to adult services are more likely to experience poor transitions. However, little is known about the care pathways of young people transitioning from forensic services. This retrospective case note review sought to examine the clinical characteristics, transition pathways and psychosocial indicators of transition outcomes amongst young people in forensic medium secure services discharged to adult services. Design/methodology/approach The electronic records of 32 young people, who transitioned from six adolescent medium secure units in England to adult services between May 2015 and June 2016, were examined. Findings Approximately 65% of young people were between 18 and 19 years at the time of transition and the average waiting time from referral to discharge was six months. A total of 63% young people transitioned to community placements and adult medium secure services. Four pathways describing the journey into and out of adolescent medium secure services were identified in a subsample of 12 young people. A total of 25% young people with neurodevelopmental problems moved to specialist services. Practical implications The results suggest that diagnosis, severity of offence and clinical background are associated with transition pathway. Promoting a person-centred approach and gradual independence of the young person may improve current practice. Originality/value These results inform existing policy and clinical practice in an effort to reform transition guidelines around young people’s needs during transition times. Further studies in adolescent forensic services are needed to understand complex neurodevelopmental problems and comorbidities.

This paper considers a dynamic and adaptive trajectory generator for negotiating paths using S-curves. Applying constant jerk transitions between the constant acceleration and deceleration periods of the trajectory, the trajectory will optimally transition to the desired speed setting. Optimal is defined to be the minimum time to transition from the current speed to the set speed for the move segment when jerk and acceleration are limited. The S-curve equations will adapt to instantaneous changes in speed setting and path length. An integrated motion planner will determine allowable speeds and transitional profiles based on the remaining move distance.
