The reproduction of gender differences in early career choices and professional identity of young dentist in Finland
Introduction For over the last 20 years, approximately 70% of working dentists in Finland have been women. However, there is internal division of the profession along gender lines. Female dentists work more often in the public sector and male dentists in the private sector. The aim of this study was to investigate the gender differences in young dentists' early career choices, specialization plans, values and perceptions of professional identity. Materials and methods The data were taken from a national e-mail questionnaire study called "Young Dentist," which was sent to 458 dentists who had received their licence to practise dentistry in 2014-2016 from all four universities with dental curricula in Finland. A total of 52% young dentists (n = 238) answered the questionnaire. Results and discussion The results indicated that whereas female dentists were more likely to perceive themselves as comforters, social workers and health promoters, male dentists tended to perceive themselves as technicians. These professional identities were interrelated with early-stage career choices in which female dentists worked more often in the public than in the private sector when compared to male dentists. There were also clear gender differences in the importance of values and the specialization plans of the young dentists. Conclusion Young dentists in Finland make career choices and develop professional identity in accordance with the attributes traditionally associated with cultural ideals related to femininity and masculinity.Peer reviewe
Tomonaga-Luttinger parameters for quantum wires
The low-energy properties of a homogeneous one-dimensional electron system
are completely specified by two Tomonaga-Luttinger parameters and
. In this paper we discuss microscopic estimates of the values of
these parameters in semiconductor quantum wires that exploit their relationship
to thermodynamic properties. Motivated by the recognized similarity between
correlations in the ground state of a one-dimensional electron liquid and
correlations in a Wigner crystal, we evaluate these thermodynamic quantities in
a self-consistent Hartree-Fock approximation. According to our calculations,
the Hartree-Fock approximation ground state is a Wigner crystal at all electron
densities and has antiferromagnetic order that gradually evolves from
spin-density-wave to localized in character as the density is lowered. Our
results for are in good agreement with weak-coupling perturbative
estimates at high densities, but deviate strongly at low
densities, especially when the electron-electron interaction is screened at
long distances. vanishes at small carrier density
whereas we conjecture that when , implying that
should pass through a minimum at an intermediate density.
Observation of such a non-monotonic dependence on particle density would allow
to measure the range of the microscopic interaction. In the spin sector we find
that the spin velocity decreases with increasing interaction strength or
decreasing . Strong correlation effects make it difficult to obtain fully
consistent estimates of from Hartree-Fock calculations. We
conjecture that v_{\sigma}/\vf\propto n/V_0 in the limit where
is the interaction strength.Comment: RevTeX, 23 pages, 8 figures include
Characteristics of Patients Presenting to Emergency Department for Primary Atrial Fibrillation or Flutter at an Academic Medical Center
OBJECTIVE: In the United States, atrial fibrillation (AF) accounts for over 400,000 hospitalizations annually. Emergency Department (ED) physicians have few resources available to guide AF/AFL (atrial flutter) patient triage, and the majority of these patients are subsequently admitted. Our aim is to describe the characteristics and disposition of AF/AFL patients presenting to the University of North Carolina (UNC) ED with the goal of developing a protocol to prevent unnecessary hospitalizations. METHODS: We performed a retrospective electronic medical chart review of AF/AFL patients presenting to the UNC ED over a 15-month period from January 2015 to March 2016. Demographic and ED visit variables were collected. Additionally, patients were designated as either having primary or secondary AF/AFL where primary AF/AFL patients were those in whom AF/AFL was the primary reason for ED presentation. These primary AF/AFL patients were categorized by AF symptom severity score according to the Canadian Cardiovascular Society Severity of Atrial Fibrillation (CCS-SAF) Scale. RESULTS: A total of 935 patients presented to the ED during the study period with 202 (21.5%) having primary AF/AFL. Of the primary AF/AFL patients, 189 (93.6%) had mild-moderate symptom severity (CCS-SAF ≤ 3). The majority of primary AF/AFL patients were hemodynamically stable, with a mean (SD) SBP of 123.8 (21.3), DBP of 76.6 (14.1), and ventricular rate of 93 (21.9). Patients with secondary AF/AFL were older 76 (13.1), p < 0.001 with a longer mean length of stay 6.1 (7.7), p = 0.31. Despite their mild-moderate symptom severity and hemodynamic stability, nearly 2/3 of primary AF/AFL patients were admitted. CONCLUSION: Developing a protocol to triage and discharge hemodynamically stable AF/AFL patients without severe AF/AFL symptoms to a dedicated AF/AFL clinic may help to conserve healthcare resources and potentially deliver more effective care
What is the evidence for the management of patients along the pathway from the emergency department to acute admission to reduce unplanned attendance and admission? An evidence synthesis
Background
Globally, the rate of emergency hospital admissions is increasing. However, little evidence exists to inform the development of interventions to reduce unplanned Emergency Department (ED) attendances and hospital admissions. The objective of this evidence synthesis was to review the evidence for interventions, conducted during the patient’s journey through the ED or acute care setting, to manage people with an exacerbation of a medical condition to reduce unplanned emergency hospital attendance and admissions.
Methods
A rapid evidence synthesis, using a systematic literature search, was undertaken in the electronic data bases of MEDLINE, EMBASE, CINAHL, the Cochrane Library and Web of Science, for the years 2000–2014. Evidence included in this review was restricted to Randomised Controlled Trials (RCTs) and observational studies (with a control arm) reported in peer-reviewed journals. Studies evaluating interventions for patients with an acute exacerbation of a medical condition in the ED or acute care setting which reported at least one outcome related to ED attendance or unplanned admission were included.
Results
Thirty papers met our inclusion criteria: 19 intervention studies (14 RCTs) and 11 controlled observational studies. Sixteen studies were set in the ED and 14 were conducted in an acute setting. Two studies (one RCT), set in the ED were effective in reducing ED attendance and hospital admission. Both of these interventions were initiated in the ED and included a post-discharge community component. Paradoxically 3 ED initiated interventions showed an increase in ED re-attendance. Six studies (1 RCT) set in acute care settings were effective in reducing: hospital admission, ED re-attendance or re-admission (two in an observation ward, one in an ED assessment unit and three in which the intervention was conducted within 72 h of admission).
Conclusions
There is no clear evidence that specific interventions along the patient journey from ED arrival to 72 h after admission benefit ED re-attendance or readmission. Interventions targeted at high-risk patients, particularly the elderly, may reduce ED utilization and warrant future research. Some interventions showing effectiveness in reducing unplanned ED attendances and admissions are delivered by appropriately trained personnel in an environment that allows sufficient time to assess and manage patients

The Current Youth Sport Culture and its Impact on Sport Participation Experiences of Low Socioeconomic Status Families
Purpose: The rise of sport specialization can jeopardize the opportunities for families of low socioeconomic status (SES) to participate in organized sport. However, obtaining an athletic scholarship may be a motivating factor for low SES youth to sport specialize. Yet, the experiences of low SES athletes in sport participation are not well known. Method: We used an Interpretative phenomenological analysis (IPA) to explore experiences of low SES families with children participating in sport and how this may be impacted by the current youth sport culture that promotes sport specialization. We engaged in semi-structured interviews with 12 low SES parents. Results: The following 4 interrelated themes emerged: (a) Benefits of youth sport participation, (b) Negatives and/or barriers to youth sport participation, (c) Strategies to get involved in youth sport, and (d) Facilitators for youth sport participation. Conclusions: Findings indicate that while low SES youth sport parents are motivated to involve their children in sports, there are many barriers that hinder their opportunities for their child to participate in organized sports. These issues are exacerbated by the current youth sport culture which emphasizes sport specialization with very few existing facilitators to involve their child in organize sport
