Improving Care of Behavioral Health Patients in a Rural Emergency Department: A Needs Assessment
Leadership and staff at a rural Critical Access Hospital (CAH)have identified the need for interventions to address the specific care issue of behavioral health patients presenting to the emergency department (ED). The ED has experienced a higher than expected number of visits, which has presented the department with challenges, especially in finding placements for patients who need inpatient treatment. ED management and staff have reported many patients have experienced long lengths of stay in the ED while waiting for beds.
A needs assessment attempts to identify characteristics of patients who remain in the ED for extended lengths of time, and the hospital and systems factors associated with these incidences. A key part of this needs assessment was identifying delays in throughput experienced by behavioral health patients.
ED records for visits that took place within a13 month period were reviewed, including a total of 519 records. Three variables were identified as being associated with increased length of stay.These were whether or not patients were screened by a Community Mental Health (CMH) social worker; whether or not law enforcement was involved with the patient encounter; and whether or not the patient was dispositioned to inpatient behavioral health treatment.
Information obtained during the needs assessment was used to inform the creation of a quality improvement tool for the purpose of continued data collection
Aqua(2,2′-bipyridyl-N,N′)(thiodiacetato-0,0′,S)zinc(II) tetrahydrate
The title complex, aqua(2,2′-bipyridy-N,N′(3-thiapentanedioate-O,S,O′)zinc(II) tetrahydrate, [Zn(C4H4-O4S)(C10H8N 2)(H2O)].4H2O, is mononuclear with a coordination sphere consisting of one S, two N and three O atoms. The Zn atom is linked to a tridentate thiodiacetate ligand, a bidentate 2,2′-bipyridine ligand and an aqua ligand resulting in a slightly distorted octahedral coordination geometry. The molecular units are linked together in the crystal by an extensive hydrogen-bonding network and by intermolecular S⋯S interactions.Fil:Baggio, R. Universidad de Buenos Aires.

Quantum correlations of twophoton polarization states in the parametric down-conversion process
We consider correlation properties of twophoton polarization states in the
parametric down-conversion process. In our description of polarization states
we take into account the simultaneous presence of colored and white noise in
the density matrix. Within the considered model we study the dependence of the
von Neumann entropy on the noise amount in the system and derive the
separability condition for the density matrix of twophoton polarization state,
using Perec-Horodecki criterion and majorization criterion. Then the dependence
of the Bell operator (in CHSH form) on noise is studied. As a result, we give a
condition for determining the presence of quantum correlation states in
experimental measurements of the Bell operator. Finally, we compare our
calculations with experimental data [doi:10.1103/PhysRevA.73.062110] and give a
noise amount estimation in the photon polarization state considered there.Comment: 10 pages, 7 figures; corrected typo
Theoretical pedagogical overview on the social efficiency curriculum
Cilj ovog istraživanja jest teorijski istražiti mogućnost odgoja i obrazovanja putem kurikuluma socijalne efikasnosti. U tu svrhu, najprije se nastoji razviti teorijska pedagogijska perspektiva kao osnova s koje će se pružiti pedagogijski pogled na kurikulum socijalne efikasnosti. Tijek razvoja te perspektive dovodi do zaključka o nužnosti slobode samoodređivanja svrhe kao preduvjeta cjelovitog i smislenog razvoja bića čovjeka, koji se ostvaruje (samo)odgojem i (samo)obrazovanjem u dijalektičnom odnosu čovjeka i društva. Daljnjim tijekom istraživanja, u kojemu se raspravlja o teorijskom konceptu kurikuluma socijalne efikasnosti, dolazi se do zaključka da su već sami preduvjeti odgoja i obrazovanja u njemu onemogućeni, budući da se radi o izvanjskom, društveno-ideološkim mehanizmima nametnutom prilagođavanju čovjeka potrebama društveno-ekonomskog sustava. Pedagogijski pogled na kurikulumsku ideologiju socijalne efikasnosti kao odraz šireg društveno-ideološkog konteksta u kojemu su potrebe tržišta stavljana ispred čovjeka, ukazuje ne samo na nemogućnost odgoja i obrazovanja kao procesa čovjekovog postajanja samim sobom, već i na potpunu neprimjerenost takvog društva općeljudskom bivanju.The aim of this research is to see into the possibility of education trough the social efficiency curriculum. For this purpose, endeavor is first made to develop theoretical pedagogical perspective as a basis for theoretical pedagogical overview on the social efficiency curriculum.
The course of development of that perspective leads to a conclusion of the necessity of freedom of self-determination of purpose as a prerequisite for the complete and meaningful development of a human being, which is achievable by (self)education in dialectical relationship between man
and society. Further course of the research, in which the theoretical concept of social efficiency curriculum is discussed, leads to a conclusion that it disables prerequisites of education, for it is about externally, by socio-ideological mechanisms imposed adaptation of man to the needs of socio-economic system. Theoretical pedagogical overview on the social efficiency curriculum ideology as a reflection of broader socio-ideological context in which needs of the market are imposed to human, shows not only that education as a proces of human's self-becoming is
impossible, but also that such society is completely inadequate for general being of human
Professionalism in sport; advantages and disadvantages
Ovim radom nastoji se ukazati na ubrzani razvoj profesionalnog sporta u Hrvatskoj, okarakterizirati ga navodeći njegove prednosti i nedostatke te istaknuti njegovu važnost u stvaranju uspješne sportske karijere svakog sportaša. Sport u tom kontekstu čine aktivnosti čija je dominanta jačanje igrom i radom istovremeno, korištenjem vlastitog slobodnog vremena za treninge i natjecanja s mogućnošću preobrazbe navedenih rekreativnih u profesionalni oblik sportskih aktivnosti.
Proces profesionalizacije sporta odnosi se na razvoj sporta kao profitabilne profesije kojom sportaši i ostali akteri sporta zarađuju za život, a najzastupljeniji je u ekipnim sportovima. Promjene u njegovoj strukturi rada i rast popularnosti doveli su do veće međusobne ovisnosti sporta i medija, ponekad za sportaša pozitivne, ponekad negativne. Veličanje sportskih uspjeha pojedinaca, nije jedino što ispunjava stranice poznatih tabloida. Često se neuspjeh i privatan život sportaša kritizira više nego što se njihov uspjeh hvali. Stoga se sa sigurnošću može reći da profesionalno bavljenje sportom sa sobom, osim brojne prednosti potrebnih za razvoj sportske karijere, donosi i nedostatke s kojima se često puno teže nositi.
Prednosti su profesionalnog sporta financijska sigurnost koja osigurava lakše pokrivanje životnih troškova, ozbiljnost, disciplina i odgovornost sportaša koja se razvija prilikom profesionalnog bavljenja sportom, zdrave navike kretanja, raznovrsnost prehrane koja je neophodna u sportskom svijetu za postizanje uspjeha, ali i izuzetna dinamičnost života ispunjena putovanjima, iskustvima te uspomenama koje ostaju za čitav život. Nedostaci su velika medijska popularnost i zadiranje u privatan život sportaša koji stvaraju stres, visok pritisak i osjećaj podcijenjenosti, veća mogućnost ozljeđivanja koja narušava opće fizičko stanje pojedinca, veća odgovornost koja prouzrokuje strah od neuspjeha, ali i ograničava mogućnost doškolovanja sportaša zbog velikog broja sportskih obaveza. Međutim, najveći nedostatak profesionalnog sporta je asocijalnost uzrokovana nedostatkom vremena koja stvara osjećaj gubitka dodira s društvom, obitelji i prijateljima. Stoga je potrebno prihvatiti njegove obje strane te pokušati izvući maksimum iz svake situacije kako bi se postigla željena slava

EXPERIMENTAL RESEARCH INTO MARBLE CUTTING BY ABRASIVE WATER JET
The article presents research on the erosion of the metamorphic rock - marble by the Abrasive Water Jet (AWJ). The fragmentation of abrasive grains during the erosion process is demonstrated. The effect of the cutting process's most important parameters as traverse speed, nozzle ID, and abrasive mass flow rate, on the maximum cutting depth, is shown. To create a mathematical-statistic model of the erosion process, the methodology of the response surface (RSM) was used for modeling. The polynomial equation of the second degree is chosen for developing the regression model. Studies have shown the optimal parameters of the process, to reach the highest depth of the cut. Additionally, the erosion wear of a focusing tube under different process conditions is presented
