description: We calculate volume-independent ratios of cumulants of the net-proton number distribution up to sixth order in a fireball that cools down after the chemical freeze-out. A hadron resonance gas model is used together with the assumption of partial chemical equilibrium, which fixes the number of observed stable hadrons after the chemical freeze-out. It is shown that due to only weak departure from the statistical Boltzmann distribution, also the volume-independent ratios of higher-order cumulants of the net-proton number show only weak dependence on the temperature. This observation supports the possibility to measure non-critical cumulants at chemical freeze-out even after subsequent cooling in the hadronic phase. Cumulants of the net-baryon number behave similarly, while those for the kaon number vary more strongly with the temperature. Our results are relevant for the current fluctuation studies of the RHIC-BES runs.

description: This article presents a new Pythagorean theorem using hexagons instead of squares. It was first published in 2021 on the Canadian Journal of Mathematical Research under a Creative Commons Attribution 4.0 International License (CC-BY 4.0) - see reference at bottom for original source - and, it is made available again here to the benefit of all that might be interested in such a topic.
****************************************************************************************************ABSTRACTThis article provides the geometric and algebraic proof of the variant equation of the Pythagorean theorem x2-xy+y2=z2. The hypothesis that will be proven is that just as squares govern the original version x2+y2=z2, hexagons are found to govern x2-xy+y2=z2. Both the special case x equal to y, and the general case of x different from y, are examined.
The development of medieval medical ethics
Creators: name: Amundsen, Darrel W
Publisher: name: University of British Columbia

description: In classical antiquity there were no restrictions on who could practise medicine. There were no enforceable professional standards. The physician sold his services at his own discretion to those who asked and paid for treatment; he exercised his art as he wished. In the early Christian centuries Christian charity and moral principles effected some significant changes in the perception of medical ethics and suggested a responsibility to exercise compassion and extend charity. Yet it is not until the late Middle Ages that we can speak of the development of a clearly-defined medical deontology and professional ethics resulting from two factors» 1) The development of licensure requirements (whether imposed by external authority or obtained by medical guilds) which reflects a fundamental change in the very basis for the practice of medicine from a right to a privilege, with specific obligations attached to that privilege. 2) The clear definition and expression by casuists of the moral responsibilities of physicians. During the late Middle Ages some physicians wrote treatises on medical etiquette and ethics. When the contents of these treatises are supplemented by guild and university ethics and the moral expectations of the casuists, as well as by the evidence of physicians' conscientious response to the various outbreaks of pestilential disease in the late Middle Ages, the picture that emerges is of relatively high ethical standards circumscribed by, and in part the result of, clearly-delineated expectations of ecclesiastical authority and the secular community.

description: When discussing consequences of symmetries of dynamical systems based on Noether's first theorem, most standard textbooks on classical or quantum mechanics present a conclusion stating that a global continuous Lie symmetry implies the existence of a time independent conserved Noether charge which is the generator of the action on phase space of that symmetry, and which necessarily must as well commute with the Hamiltonian. However this need not be so, nor does that statement do justice to the complete scope and reach of Noether's first theorem. Rather a much less restrictive statement applies, namely that the corresponding Noether charge as an observable over phase space may in fact possess an explicit time dependency, and yet define a constant of the motion by having a commutator with the Hamiltonian which is nonvanishing, thus indeed defining a dynamical conserved quantity. Furthermore, and this certainly within the Hamiltonian formulation, the converse statement is valid as well, namely that any dynamical constant of motion is necessarily the Noether charge of some symmetry leaving the system's action invariant up to some total time derivative contribution. The present contribution revisits these different points and their consequences, straightaway within the Hamiltonian formulation which is the most appropriate for such issues. Explicit illustrations are also provided through three general but simple enough classes of systems.

description: We report $^{57}$Fe-NMR studies on the oxygen-deficient iron (Fe)-based oxypnictide superconductor LaFeAsO$_{0.7}$ ($T_{c}=$ 28 K) enriched by $^{57}$Fe isotope. In the superconducting state, the spin component of $^{57}$Fe-Knight shift $^{57}K$ decreases almost to zero at low temperatures and the nuclear spin-lattice relaxation rate $^{57}(1/T_{1})$ exhibits a $T^{3}$-like dependence without the coherence peak just below $T_{c}$, which give firm evidence of the unconventional superconducting state formed by spin-singlet Cooper pairing. All these events below $T_c$ are consistently argued in terms of the extended s$_{\pm}$-wave pairing with a sign reversal of the order parameter among Fermi surfaces. In the normal state, we found the remarkable decrease of $1/T_1T$ upon cooling for both the Fe and As sites, which originates from the decrease of low-energy spectral weight of spin fluctuations over whole ${\bm q}$ space upon cooling below room temperature. Such behavior has never been observed for other strongly correlated superconductors where an antiferromagnetic interaction plays a vital role in mediating the Cooper pairing.

description: The standard equilibrium equation for magnetized plasma is extended to account for the magnetic polarization force. A factor of the pressure gradient arising from the magnetic decomposition of the Hall term survives the limit of vanishing magnetization and is canceled by a contribution from the magnetic polarization force, such that the proposed equation reduces to the standard form in the free current limit. Comparison of the solutions for an axially symmetric plasma column indicates agreement with the free current limit for vanishing magnetization and variation in the field and current profiles as the degree of magnetization increases.

description: We study the effects of thickness on the ground states of two-dimensional quantum dots in high magnetic fields. To be specific, we assume the thickness to be small so that only the lowest state in the corresponding direction is occupied, but which however leads to a modification of the effective interaction between the electrons. We find the ground state phase diagram and demonstrate the emergence of new phases as the thickness is accounted for. Finally, the wave functional form and vortex structure of different phases is analyzed.

Spatial entanglement of fermions in one-dimensional quantum dots

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The time dependent quantum Monte Carlo method for fermions is introduced and applied for calculation of entanglement of electrons in one-dimensional quantum dots with several spin-polarized and spin-compensated electron configurations. The rich statistics of wave functions provided by the method allows one to build reduced density matrices for each electron and to quantify the spatial entanglement using measures such as quantum entropy by treating the electrons as identical or distinguishable particles. Our results indicate that the spatial entanglement in parallel-spin configurations is rather small and it is determined mostly by the quantum nonlocality introduced by the ground state. By contrast, in the spin-compensated case the outermost opposite-spin electrons interact like bosons which prevails their entanglement, while the inner shell electrons remain largely at their Hartree-Fock geometry. Our findings are in a close correspondence with the numerically exact results, wherever such comparison is possible.

description: Background: The habitual or excessive use of painkillers, including prescription and over-the-counter drugs, that deviates from medical guidelines is known as analgesic abuse, and this includes taking larger doses than recommended, using the drugs for non-medical purposes, or continuing to take the medication despite adverse effects on one's physical, mental, and social well-being. Devastating health effects may result from this. The prevalence and patterns of analgesic abuse among University of Port Harcourt undergraduate students were evaluated in this study. 

 

Methodology: A descriptive cross-sectional study was conducted, and respondents were selected using a multistage sampling method. A self-administered, structured questionnaire was used to gather the data, and IBM Statistical Product for Service Solution (SPSS) version 25 was used to analyze the data; means, frequency, proportions, chi-square, and regression analysis were used to summarize the results. A p-value of less than 0.05 was deemed statistically significant.

 

Results: 384 students in all, with a median age of 20, were interviewed. The distribution of results showed that 207 (53.9%) of the respondents were males and 177 (46.1%) were females. The majority of responders, 339 (69.6%), used paracetamol, with headaches accounting for 316 (57.4%) of all uses. The findings also showed that the prevalence of analgesic abuse was 9.1%, with paracetamol being the most frequently abused medicine (42.9%). 

 

Conclusion: Although the results indicated that the prevalence of analgesic abuse among University of Port Harcourt undergraduate students was low, most respondents used analgesic medication without a prescription from a doctor. The most common reasons for using analgesics were headaches, muscle pain, and menstrual cramps. It is crucial that the institution implements strategic plans to ensure that students are taught how to use analgesics properly.

description: Background: Coronavirus Disease of 2019 (Covid-19) was arguably the greatest global health threat of our time. Immediately the pandemic was declared by WHO, countries around the world took broad public health and social measures (PHSM), including closure of schools, to prevent the spread of the SARS-CoV-2 virus, which causes COVID-19. The COVID-19 pandemic posed an enormous risk to the health and safety of learners, teachers, parents, school administrators, education practitioners, and the wider community. However, reopening schools carried the public health risk of viral resurgence. This study aimed to assess the compliance to COVID-19 preventive measures among secondary schools in Nnewi North LGA of Anambra state, Nigeria using WHO checklist.

 

Methodology: This was a facility-based cross-sectional observational survey of secondary schools within Nnewi North local government area of Anambra state. Data was collected through school surveys and observations of compliance measures, both done during the same school visit. Informed consent was obtained from the principal of each school or their representative before carrying out the study in their facilities.

 

Results: Out of the schools sampled, 12 schools (38.71%) had good compliance, 9 schools (29.03%) had moderate compliance, and 10 schools (32.26%) had poor compliance. The finding of this study thus revealed that the overall compliance level toward COVID-19 preventive and control measures among secondary schools in Nnewi-North LGA of Anambra state was 38.71%.

 

Conclusion: The common restraining factors against compliance to standard COVID-19 preventive measures included the fact that the students are children (aged between 11 – 18 years) and thus wouldn’t always wear their masks, school ownership, attitude towards, and risk perception of COVID-19 and these factors significantly influenced the adherence of each school towards COVID-19 mitigation measures.

description: In most nuclear many-body methods, observables are calculated using many-body wave functions explicitly. The variational two-particle reduced density matrix method is one of the few exceptions to the rule. Ground-state energies of both closed-shell and open-shell nuclear systems can indeed be evaluated by minimizing a constrained linear functional of the two-particle reduced density matrix. However, it has virtually never been used in nuclear theory, because nuclear ground states were found to be well overbound, contrary to those of atoms and molecules. Consequently, we introduced new constraints in the nuclear variational two-particle reduced density matrix method, developed recently for atomic and molecular systems. Our calculations then show that this approach can provide a proper description of nuclear systems where only valence neutrons are included. For the nuclear systems where both neutrons and protons are active, however, the energies obtained with the variational two-particle reduced density matrix method are still overbound. The possible reasons for the noticed discrepancies and solutions to this problem will be discussed.

description: We study surface energies depending on the mean curvature in total spaces of Killing submersions, which extend the classical notion of Willmore energy. Based on a symmetry reduction procedure, we construct vertical tori critical for these mean curvature energies. These vertical tori are based on closed curves critical for curvature energy functionals in Riemannian 2-space forms. The binormal evolution of these critical curves in Riemannian 3-space forms generates rotational tori solutions for an ample family of Weingarten surfaces. Therefore, we also introduce some correspondence results between these two types of tori and illustrate their relation.
Lepton Flavour Violating Heavy Higgs Decays Within the nuMSSM and Their Detection at the LHC

description: Within the $ν$MSSM, a Minimal Supersymmetric neutrino See-saw Model, Lepton Flavour Violating Higgs couplings are strongly enhanced at large $\tanβ$ ($\gsim30$), which can lead to BR$(H^0/A^0 \to τμ) \simeq O(10^{-4})$, for $M_{H^0/A^0}\gsim 160$ GeV. Enhancements on the production of Higgs bosons, through the gluon fusion mechanism, $gg\to H^0/A^0$, and the associated production channel $gg,q\bar q\to b\bar bH^0/A^0$, whose rates grow with $\tanβ$, as well as the mass degeneracy that occurs between the $H^0$ and $A^0$ states in this regime, also contribute to further the possibilities to detect a heavy Higgs signal into $τμ$ pairs. We show that the separation of $τμ$ Higgs events from the background at the upcoming CERN Large Hadron Collider could be done for Higgs masses up to about 600 GeV for 300 fb$^{-1}$ of luminosity, for large $\tanβ$ values. However, even with as little as 10 fb$^{-1}$ one can probe $H^0/A^0$ masses up to 400 GeV or so, if $\tanβ=60$. Altogether, these processes then provide a new Higgs discovery mode as well as an independent test of flavour physics.

description: Background: In children, HIV infection presents with grave consequences, including a predisposition to emotional and behavioural problems (EBP). These are mental health problems affecting thoughts, emotions, behaviours and relationships, and may be categorised into emotional problems (EP) and behavioural problems (BP). Studies have shown a high burden of EBP in children; however, knowledge gaps still exist regarding the burden of EBP on HIV-infected children. Our study seeks to address these gaps by determining the prevalence and type of EBP among HIV-infected children.

 

Methodology: This cross-sectional and comparative study enrolled 386 participants (193 subjects and 193 controls). The subjects were HIV-infected children aged 2-15 years attending the Paediatric HIV Clinic of Federal Medical Centre, Umuahia. The controls were age and sex-matched HIV-negative children attending primary or secondary schools in Umuahia. Sociodemographic characteristics were assessed, and EBP was determined using the strengths and difficulties questionnaire.

 

Results: Sixty-one subjects (31.6%) had EBP compared to 15 controls (7.8%) and this difference was significant (p<0.001). The subjects were three times more likely to have EBP than the controls (aOR=3.03; CI=1.17-7.82). The EBP type showed that, while there was no significant difference in the multivariate analysis of the behavioural problems, emotional problems were significantly higher in the subjects than in the controls (p = 0.001). The subjects were six times more likely to have emotional problems than the controls (aOR=6.26; CI=2.80-13.97).

 

Conclusion: There is a high burden of EBP among HIV-infected children in Umuahia with emotional problems as the common type.

X-ray burst ignition location on the surface of accreting X-ray pulsars: Can bursts preferentially ignite at the hotspot?

description: Hotspots on the surface of accreting neutron stars have been directly observed via pulsations in the lightcurves of X-ray pulsars. They are thought to occur due to magnetic channelling of the accreted fuel to the neutron star magnetic poles. Some X-ray pulsars exhibit burst oscillations during Type I thermonuclear X-ray bursts which are thought to be caused by asymmetries in the burning. In rapidly rotating neutron stars, it has been shown that the lower gravity at the equator can lead to preferential ignition of X-ray bursts at this location. These models, however, do not include the effect of accretion hotspots at the neutron star surface. There are two accreting neutron star sources in which burst oscillations have been observed to track exactly the neutron star spin period. We analyse whether this could be due to the X-ray bursts igniting at the magnetic pole of the neutron star, because of heating in the accreted layers under the hotspot causing ignition conditions to be reached earlier. We investigate heat transport in the accreted layers using a 2D model and study the prevalence of heating down to the ignition depth of X-ray bursts for different hotspot temperatures and sizes. We perform calculations for accretion at the pole and at the equator, and infer that ignition could occur away from the equator at the magnetic pole for hotspots with temperatures greater than $1\times10^8$ K. However, current observations have not identified such high temperatures in accreting X-ray pulsars.

description: Spatiotemporal properties of two-dimensional (2D) Hall-magnetohydrodynamic turbulence at intermediate plasma $β=2$ are studied by means of Fast Iterative Filtering, a new technique for the decomposition of nonstationary nonlinear signals. Results show that the magnetic energy at sub-ion scales is concentrated in perturbations with frequencies smaller than the ion-cyclotron (IC) frequency and with polarization properties that are incompatible with both kinetic Alfvén waves (KAWs) and IC waves. At higher frequencies, we clearly identify signatures of both whistler waves and KAWs, however their energetic contribution to the magnetic power spectrum is negligible. We conclude that the dynamics of 2D Hall-MHD turbulence at sub-ion scales is mainly driven by localized intermittent structures, with no significant contribution of wavelike fluctuations.

description: Let $n=\prod_p p^{ν_p(n)}$ denote the canonical factorization of $n\in \N$. The binomial convolution of arithmetical functions $f$ and $g$ is defined as $(f\circ g)(n)=\sum_{d\mid n} (\prod_p \binom{ν_p(n)}{ν_p(d)}) f(d)g(n/d),$ where $\binom{a}{b}$ is the binomial coefficient. We provide properties of the binomial convolution. We study the $\C$-algebra $({\cal A},+,\circ,\C)$, characterizations of completely multiplicative functions, Selberg multiplicative functions, exponential Dirichlet series, exponential generating functions and a generalized binomial convolution leading to various Möbius-type inversion formulas. Throughout the paper we compare our results with those of the Dirichlet convolution *. Our main result is that $({\cal A},+,\circ,\C)$ is isomorphic to $({\cal A},+,*,\C)$. We also obtain a "multiplicative" version of the multinomial theorem.

description: Background: Disparities exist in aortic blood pressure (aBP) and brachial blood pressure (bBP) and between aortic (AH) versus brachial hypertension (BH). While the former is superior, it is studied scarcely. Pulse wave analysis (PWA) provides objective and simultaneous measurement of both blood pressures to determine AH and BH. Using PWA, we compared prevalent AH and BH in a sample adult population.

 

Methodology: By oscillometric PWA (Mobilograph, IEM, Stolberg, Germany), 1187 participants with age >18 years were evaluated. Simultaneous aBP and bBP were recorded by standard PWA protocol and prevalence of AH and BH was estimated. Age and gender-based subgroups were compared for aortic versus brachial BP differences. Prevalence of Hypertension, Isolated Systolic Hypertension, and Pulse Pressure ≥40 was compared between aortic versus brachial criteria.

 

Results: Significant differences were seen between bBP and aBP across all age groups and in both genders, especially for the younger age groups. As compared to bBP, aBP gave a higher fetch for prevalent hypertension and a lower fetch for prevalent Isolated Systolic Hypertension (ISH). bPP ≥40 was sensitive but not specific as a surrogate for aPP ≥ 40.

 

Conclusions: Across ages 18-65 in either sex, disparities exist between bBP and aBP mostly for SBP and PP with significant differences in prevalent Hypertension, Isolated Systemic Hypertension, and high pulse pressure. It reaffirms disparities of aBP and bBP and diagnosed brachial or central hypertension based on them with the need for further work.

description: We study shedding in the setting of data linkage dynamics, a simple model of computation that bears on the use of dynamic data structures in programming. Shedding is complementary to garbage collection. With shedding, each time a link to a data object is updated by a program, it is determined whether or not the link will possibly be used once again by the program, and if not the link is automatically removed. Thus, everything is made garbage as soon as it can be viewed as garbage. By that, the effectiveness of garbage collection becomes maximal.

description: Sickle cell disease is an inherited disorder of haemoglobin formation, predominantly affecting individuals of African, Indian, or Mediterranean descent. Acute painful episodes frequently occur in these patients due to the blockage of small blood vessels by sickled cells, leading to tissue infarction. Two children of Nigerian descent, presented with severe headaches during a painful crisis episode with associated swelling on their scalps. CT imaging in both cases showed subgaleal haematoma which was managed conservatively in addition to managing the painful crisis with a good outcome. This report highlights the clinical presentation, diagnostic approach, and management of this uncommon complication of sickle cell anaemia.

description: Background: In Nigeria, Ovarian cancer is the most lethal gynaecologic cancer. The management of disease in developing countries poses a huge challenge due to late presentation and/or diagnosis, poverty, poor health insurance coverage, and the dearth of specialists in the region amongst others. Record keeping is poor. Treatment options are limited with high default rates and mortality. This was a five-year review of clinicopathology and treatment strategies for ovarian cancers in Ahmadu Bello University Teaching Hospital, Zaria.

 

Methodology: A retrospective study of all primary ovarian cancers diagnosed and or treated in ABUTH Zaria from 1st January 2016 to 31st December 2020 was carried out. A total of 38 cases were retrieved and relevant data was extracted. The data collected were entered into Open Data Kit (ODK) and analysed using descriptive statistics.

 

Results: Most patients were aged 35 to 54 years with an overall mean age of 51.2 ±13.8 years. Only 34% of patients were nulliparous and 63.2% were post-menopausal. The commonest symptoms were abdominal swelling (94.7%), and abdominal pain (68.4%). Epithelial carcinomas (81.8%) were the commonest histotype of which serous adenocarcinoma (85.1%) was the commonest. There was no distinction between high-grade and low-grade serous carcinomas. Rare ovarian tumours (germ cell and sex cord/stromal) accounted for 18.2%. Most patients presented with stage III disease and above (77.7%) with no one presenting at stage I. Thirty-five patients (92.1%) had surgery, twenty-four (63.2%) had chemotherapy and four patients (10.5%) had targeted therapy. No patient had hormonal therapy, genetic testing, Poly-adenosine diphosphate-ribose polymerase inhibitors (PARPi), Hyperthermic intraperitoneal chemotherapy (HIPEC), or palliative radiotherapy. Only 12% had an MDT discussion. One-year post-diagnosis, the majority were lost to follow-up (73.7%) while 21.1% of patients were still on follow-up.

 

Conclusion: Ovarian cancer patients in ABUTH were relatively younger, unemployed, multiparous, and symptomatic. Some standards of care management practices were omitted.

„Die Lehrerin, die das gesagt hat, hat so recht: Die Schule mit ihren Fachleuten kann einen überaus wertvollen Beitrag leisten, insbesondere auch für Kinder mit einer Fluchtgeschichte. Fluchtgeschichten gibt es viele, aus unterschiedlichen Gründen und aus vielen verschiedenen Richtungen. Viele der Geflüchteten haben Entsetzliches erlebt und sind davon stark belastet. Sie kommen aus einer anderen Lebenswelt und müssen sich in einer für sie fremden Umgebung zurechtfinden, ohne die lokale Sprache zu sprechen und ohne Worte zu finden für das Erlebte. Die Herausforderungen sind oft enorm gross. Lehrpersonen und andere Bildungsfachleute stellen in diesen Zusammenhängen wichtige Fragen. Auf zehn der häufigsten Fragen gehen wir im Folgenden ein. Wir konzentrieren uns dabei auf den ersten und zweiten Zyklus.“.[S.2]

Projecting health care system outcomes due to lifestyle changes

description: Health promotion has been identified as a practical inexpensive strategy to reduce hospital costs in Canada. Unfortunately there is a dearth of information about this, and also the actual impact of improved lifestyles on health status, illness and death. In fact, there is even an apprehension that by avoiding premature mortality the numbers and needs of the elderly will increase dramatically, resulting in cost increases. This thesis attempts to resolve this issue by projecting hospital use by Canadians and resultant cost savings or increases based on assumptions concerning improvements in lifestyles. Four steps were required: first, mortality rates were reduced based on assumed improvements in lifestyles; second, a population model was chosen to project population for the short-term (25 years) and long-term (500 years to stable state); third, hospital utilization rates were reduced consistent with reductions in mortality; and fourth, future hospital use and costs were calculated and their burden on society determined. The overall effect of improving lifestyles was a decrease in age-specific mortality rates especially for males and the elderly. Reducing premature mortality resulted in both slight increases in both the stable population's total size and proportion of elderly in the population. The dependency ratio remained relatively constant. Age-specific hospital use decreased, but increases in the number of elderly offset this decrease so that there was a slight overall increase in use and associated costs. This resulted in only slight per capita costs increases for the productive (20-64) age groups. Therefore, the thesis has determined that health promotion by itself will not have a significant effect in either increasing or decreasing costs of hospital care in the long term. However, health promotion was identified as a viable strategy which at very little expense will postpone a significant proportion of premature mortality, allow more persons to reach old age, and result in a more vigorous population. The increased numbers of elderly and their impact on the structure and components of the health and illness care system were identified. Future research into the question of cost effectiveness of health promotion would require a much improved data base, especially in the area of morbidity and hospital care. However, it was suggested that more productive research efforts might seek to identify optimal methods of modifying and improving lifestyles, such as long-term demonstration projects with evaluation components. There was sufficient evidence found to conclude that health promotion should be advanced as a viable and necessary component of the Canadian health care system.
The future role of the health record administrator : a Delphi-survey
Creators: name: Szabo, Irma
Publisher: name: University of British Columbia

description: The voluntary North American accreditation movement, born at the beginning of this century with the intent to improve the standards of medical care and teaching, decreed that the clinical records should reflect the care given to the patients. As a consequence, the occupation of Medical Record Librarian, recently renamed Health Record Administrator, has grown rapidly over the past few decades. In Canada, this growth was more numerical than substantive, and the types and quality of health record administration services—discussed later, did not meet the needs of the health care system. Within the occupation, there is serious concern about its continued viability. For these various reasons, the adaptability of the health record administrator to the scientific, technological and social changes taking place in the health field is investigated here. To study the question, the health record administrator occupation was examined in the context of the changing status of health information within the Canadian health care delivery system and the jostling professionalization of the health occupations. These two major forces are believed to have great impact upon the health record administrator occupation in its quest for survival. The Delphi-method developed by the Rand Corporation was used to elicit the predictions of some members of the health occupations as to the potential development or regression of the role of the Health Record Administrator in the future. The findings of this study show that the health occupations, and particularly the medical profession have acknowledged needs for health information and health information management services. They have forecast a strong administrative role for the future Health Record Administrator, while giving equal importance to a participative role as collaborator providing the health occupations with the information services that they require for the performance of their own duties. They also visualize the integration of the various sectors of the health field with the Health Record Administrator being a potential agent of this integration process.
