Jeremia 20:7-13 psykoanalyysissa : Nimettömän valituslaulun syntyprosessi tekstin objektimielikuvien muutosten valossa

Tämän pro gradu -työn tarkoituksena on selvittää tekstin Jer 20:7-13 jumalakuvaa ja muita ”tekstin puhujan” ilmaisemia vuorovaikutussuhteita ja vaihtelevia tunteita. On kuitenkin epäselvää, missä määrin Jeremian kirja tai sen yksittäiset jaksot kuvaavat profeetan persoonaa ja historiallista taustaa. Tekstit voivat kuvata myös muita myöhempiä tilanteita ja asenteita. Tämän tutkimuksen pääasiallinen eksegeettinen metodi on syvyyspsykologinen. Se saattaa pystyä kertomaan jotakin siitä, miten tutkittava teksti peilaa menneisyyden kokemuksellisia kaavoja. Samaan tapaan kuten psykohistoriassa, tutkimus ei yritä tutkia, tulkita tai rekonstruoida tradition tai historian Jeremiaa. Syvyyspsykologinen eksegeesi on tunnistettu jo aiemmin, mutta suomalaisessa tutkimuksessa sitä ei vielä ole sovellettu yksittäisiin teksteihin. Tämän tutkimuksen tutkimusasetelma avaa tekstin sisäisiä ja vaihtelevia vuorovaikutussuhteita eli objektisuhteita. Tutkimus nimittää tätä vuorovaikutussuhteiden analyysiä objektisuhdeanalyysiksi. Se perustuu teologian tohtori, psykoanalyytikko Matti Hyrckin psykoanalyyttiseen suhteessaolon perusmielikuvien teoriaan (SPT), jonka hän esittelee väitöskirjassaan Mielen kuvat Jumalasta (1995). Tekstin Jahve-kuvat on nähtävä objektirepresentaatioina. Nämä vahvasti värittyneet representaatiot ja kuvat kertovat enemmän kokijasta itsestään kuin niistä objekteista, joiden kuviksi ne ovat syntyneet. Käsitys objektien sisäsyntyisyydestä mahdollistaa Hyrckillä objektisuhteiden systematisoinnin ja SPT:n luomisen. Siten emotionaaliset silmälasit on tämän tutkimuksen tekijän mielestä mahdollista valjastaa myös tutkijan käyttöön. Tutkimuksen laaja näkökulmia hakeva teoriaosuus varmistaa tämän. Hermeneuttinen ”kolmen maailman malli” on lukijakeskeisyyteen ja kulttuurihyppyyn arvokas työväline. Jeremian kirja sisältää useita osin runomuotoisia valituksia, joista tutkittava teksti on viimeinen. Valituslaulujen sarja päättyy tutkittavaa tekstiä seuraavaan syntymäpäivän kiroamiseen jakeissa 14-18. Valituksen edellä kontekstina on joitakin kertomuksia Jeremiasta, mutta vasta jakeessa 20:2 Jeremia nimetään profeetaksi. Muuten valittaja on nimetön. Jeremia-kertomusten kehys on tässä toimituksellinen ja valituksen jälkeen seuraa deuteronomistista saarnaa Juudaa ja Jerusalemia vastaan. Tutkimus selvittää jakeiden 7-13 rakennetta, sisältöä ja tulkintaa ensin lähinnä laji- ja kirjallisuus- kriittisesti. Tutkimus osoittaa, että Jeremian valitus noudattaa yksilön valituslaulun kaavaa, mutta ei kuitenkaan yksiselitteisesti taivu lajin usein stereotyyppisiin tarkoituksiin. Suurin syy tähän on tekstin proosa- ja runomuodon vaihtelu ja sisällön hajanaisuus. Edes valituksen ydintä ei voi varmistaa, vaikka valituslaulun nuorimpina osina on tyypillisesti helppo pitää loppupuolen kollektiivisia lisiä. Varsinainen valitus on jakeissa 7-9 ja jakeet 10-13 ovat todennäköisimmin monivaiheinen päätössarja. Tutkimuksen keskeiset objektisuhdeteoreettiset peruskäsitteet sisäinen subjekti ja sisäinen objekti ovat ihmisen tiedostamattoman tason mielikuvia. Varhaisen tilan vuorovaikutusmielikuvien sisäisinä subjekteina ovat Riippuvainen ja Itseriittoinen. Ne ovat vaihtelevissa suhteissa Houkuttajan ja Hallitsijan muotoisia sisäisiä objekteja kohtaan. Myöhäisessä tilassa objekteille on syytä antaa uudet nimet: Vetäytyjä, Vaatija ja Parantaja. Tutkimus etenee osoittamalla tekstin ja SPT:n mukaisen mallin samankaltaisuuksia. Samalla on ollut mahdollista ottaa kantaa myös tekstin saumoihin ja tekstin syntyprosessiin. Tekstin objekti osoittautuu pääosin Hallitsijaksi, sillä Houkuttajan muotoisista jumaluuksista on kollektiivisesti pyritty tekemään pesäeroa Jerusalemin temppelin hävityksestä lähtien. Silti muistoista ja Houkuttajaksikin värittyneistä kaipuun ja pelon muodoista ei päästä eroon. Valituksen alkujakeita 7-9 leimaa Riippuvaisen masennus ja Itseriittoisen häpeä. Jakeissa 11-13 Hallitsijan muotoinen Jahve Sebaot tarjoaa hierarkkista symbioosia. Myöhäistä Vaatijaa ei tutkittavassa tekstissä ole kuin vanhurskaan käsitteenä, joka deuteronomistisessa teologiassa perustuu Jahven sanan kuulemiseen ja lain noudattamiseen. Tutkimus pyrkii osoittamaan, että kaikilla kokemuksilla on jollakin tavalla sekä yhteisöä että yksilöä eheyttäviä tarkoituksia. Kun valitus päättyy sarjaan vakuutuksia ja huipentuu kollektiiviseen ylistyskehotukseen, myös niillä on tarkoitus. Yksi osa tutkimustehtävää on ollut testata psykoanalyyttisen objektisuhdeteoreettisen metodin toimivuutta eksegeettisessä tutkimuksessa. Vaikka tulokset ovat suuntaa antavia, metodi on osoittautunut toimivaksi.

Surveillance of Surgical Site Infections following Major Hip and Knee Surgery in Finland

Background and aims. Since 1999, hospitals in the Finnish Hospital Infection Program (SIRO) have reported data on surgical site infections (SSI) following major hip and knee surgery. The purpose of this study was to obtain detailed information to support prevention efforts by analyzing SIRO data on SSIs, to evaluate possible factors affecting the surveillance results, and to assess the disease burden of postoperative prosthetic joint infections in Finland. Methods. Procedures under surveillance included total hip (THA) and total knee arthroplasties (TKA), and the open reduction and internal fixation (ORIF) of femur fractures. Hospitals prospectively collected data using common definitions and written protocol, and also performed postdischarge surveillance. In the validation study, a blinded retrospective chart review was performed and infection control nurses were interviewed. Patient charts of deep incisional and organ/space SSIs were reviewed, and data from three sources (SIRO, the Finnish Arthroplasty Register, and the Finnish Patient Insurance Centre) were linked for capture-recapture analyses. Results. During 1999-2002, the overall SSI rate was 3.3% after 11,812 orthopedic procedures (median length of stay, eight days). Of all SSIs, 56% were detected after discharge. The majority of deep incisional and organ/space SSIs (65/108, 60%) were detected on readmission. Positive and negative predictive values, sensitivity, and specificity for SIRO surveillance were 94% (95% CI, 89-99%), 99% (99-100%), 75% (56-93%), and 100% (97-100%), respectively. Of the 9,831 total joint replacements performed during 2001-2004, 7.2% (THA 5.2% and TKA 9.9%) of the implants were inserted in a simultaneous bilateral operation. Patients who underwent bilateral operations were younger, healthier, and more often males than those who underwent unilateral procedures. The rates of deep SSIs or mortality did not differ between bi- and uni-lateral THAs or TKAs. Four deep SSIs were reported following bilateral operations (antimicrobial prophylaxis administered 48-218 minutes before incision). In the three registers, altogether 129 prosthetic joint infections were identified after 13,482 THA and TKA during 1999-2004. After correction with the positive predictive value of SIRO (91%), a log-linear model provided an estimated overall prosthetic joint infection rate of 1.6% after THA and 1.3% after TKA. The sensitivity of the SIRO surveillance ranged from 36% to 57%. According to the estimation, nearly 200 prosthetic joint infections could occur in Finland each year (the average from 1999 to 2004) after THA and TKA. Conclusions. Postdischarge surveillance had a major impact on SSI rates after major hip and knee surgery. A minority of deep incisional and organ/space SSIs would be missed, however, if postdischarge surveillance by questionnaire was not performed. According to the validation study, most SSIs reported to SIRO were true infections. Some SSIs were missed, revealing some weakness in case finding. Variation in diagnostic practices may also affect SSI rates. No differences were found in deep SSI rates or mortality between bi- and unilateral THA and TKA. However, patient materials between these two groups differed. Bilateral operations require specific attention paid to their antimicrobial prophylaxis as well as to data management in the surveillance database. The true disease burden of prosthetic joint infections may be heavier than the rates from national nosocomial surveillance systems usually suggest.

Melting of an Anchored Bilayer: Phase Transitions in the Organic-Inorganic Hybrid Pervoskite (CH3NH3)(CH3(CH2)(n)NH3)(2)Pb2I7 (n=11, 13, 15, 17)

The conformation, organization, and phase transitions of alkyl chains in organic-inorganic hybrids based on the double pervoskite-slab lead iodides, (CH3NH3)(CH3(CH2)(n)NH3)(2)Pb2I7 (n = 11, 13, 15, 17) have been investigated by X-ray diffraction, calorimetry, and infrared vibrational spectroscopy. In these hybrid solids, double pervoskite (CH3NH3)Pb2I7 slabs are interleaved with alkyl ammonium chains with the anchored alkyl chains arranged as tilted bilayers and adopting a planar all-trans conformation at room temperature. The (CH3NH3)(CH3(CH2)(n)NH3)(2)Pb2I7 compounds exhibit a single reversible phase transition above room temperature with the associated enthalpy change varying linearly with alkyl chain length. This transition corresponds to the melting in two-dimensions of the alkyl chains of the anchored bilayer and is characterized by increased conformational disorder of the methylene units of the chain and loss of tilt angle coherence leading to an increase in the interslab spacing. By monitoring features in the infrared spectra that are characteristic of the global conformation of the alkyl chains, a quantitative relation between conformational disorder and melting of the anchored bilayer is established. It is found that, irrespective of the alkyl chain length, melting occurs when at least 60% of the chains in the anchored bilayer of (CH3NH3)(CH3(CH2)(n)NH3)(2)Pb2I7 have one or more gauche defects. This concentration is determined by the underlying lattice to which the alkyl chains are anchored.

Hybrid peptide design. Hydrogen bonded conformations in peptides containing the stereochemically constrained gamma-amino acid residue, gabapentin

he crystal structure of 12 peptides containing the conformationally constrained 1-(aminomethyl)cyclohexaneacetic acid, gabapentin (Gpn), are reported. In all the 39 Gpn residues conformationally characterized so far, the torsion angles about the C-alpha-C-beta and C-beta-C-gamma bonds are restricted to the gauche conformation (+/- 60 degrees). The Gpn residue is constrained to adopt folded conformations resulting in the formation of intramolecularly hydrogen-bonded structures even in short peptides. The peptides Boc-Ac(6)c-Gpn-OMe 1 and Boc-Gpn-Aib-Gpn-Aib-OMe 2 provide examples of C-7 conformation; peptides Boc-Gpn-Aib-OH 3, Boc-Ac(6)c-Gpn-OH 4, Boc-Val-Pro-Gpn-OH 5, Piv-Pro-Gpn-Val-OMe 6, and Boc-Gpn-Gpn-Leu-OMe 7 provide examples of C-9 conformation; peptide Boc-Ala-Aib-Gpn-Aib-Ala-OMe 8 provides an example of C-12 conformation and peptides Boc-beta Leu-Gpn-Val-OMe 9 and Boc-beta Phe-Gpn-Phe-OMe 10 provide examples of C-13 conformation. Gpn peptides provide examples of backbone expanded mimetics for canonical alpha-peptide turns like the gamma (C-7) and the beta (C-10) turns. The hybrid beta gamma sequences provide an example of a mimetic of the C-13 alpha-turn formed by three contiguous alpha-amino acid residues. Two examples of folded tripeptide structures, Boc-Gpn-beta Phe-Leu-OMe 11 and Boc-Aib-Gpn-beta Phg-NHMe 12, lacking internal hydrogen bonds are also presented. An analysis of available Gpn residue conformations provides the basis for future design of folded hybrid peptides.

Tendency toward crossover of the effective susceptibility exponent from its doubled Ising value to its doubled mean-field value near a double critical point

The critical behavior of osmotic susceptibility in an aqueous electrolyte mixture 1-propanol (1P)+water (W)+potassium chloride is reported. This mixture exhibits re-entrant phase transitions and has a nearly parabolic critical line with its apex representing a double critical point (DCP). The behavior of the susceptibility exponent is deduced from static light-scattering measurements, on approaching the lower critical solution temperatures (TL’s) along different experimental paths (by varying t) in the one-phase region. The light-scattering data analysis substantiates the existence of a nonmonotonic crossover behavior of the susceptibility exponent in this mixture. For the TL far away from the DCP, the effective susceptibility exponent γeff as a function of t displays a nonmonotonic crossover from its single limit three-dimensional (3D)-Ising value ( ∼ 1.24) toward its mean-field value with increase in t. While for that closest to the DCP, γeff displays a sharp, nonmonotonic crossover from its nearly doubled 3D-Ising value toward its nearly doubled mean-field value with increase in t. The renormalized Ising regime extends over a relatively larger t range for the TL closest to the DCP, and a trend toward shrinkage in the renormalized Ising regime is observed as TL shifts away from the DCP. Nevertheless, the crossover to the mean-field limit extends well beyond t>10−2 for the TL’s studied. The observed crossover behavior is attributed to the presence of strong ion-induced clustering in this mixture, as revealed by various structure probing techniques. As far as the critical behavior in complex or associating mixtures with special critical points (like the DCP) is concerned, our results indicate that the influence of the DCP on the critical behavior must be taken into account not only on the renormalization of the critical exponent but also on the range of the Ising regime, which can shrink with decrease in the influence of the DCP and with the extent of structuring in the system. The utility of the field variable tUL in analyzing re-entrant phase transitions is demonstrated. The effective susceptibility exponent as a function of tUL displays a nonmonotonic crossover from its asymptotic 3D-Ising value toward a value slightly lower than its nonasymptotic mean-field value of 1. This behavior in the nonasymptotic, high tUL region is interpreted in terms of the possibility of a nonmonotonic crossover to the mean-field value from lower values, as foreseen earlier in micellar systems.

The Exeter Contemporary flanged cemented acetabular component in primary total hip arthroplasty

Aims: We report on the outcome of the Exeter Contemporary flanged cemented all-polyethylene acetabular component with a mean follow-up of 12 years (10 to 13.9). This study reviewed 203 hips in 194 patients. 129 hips in 122 patients are still in situ; 66 hips in 64 patients were in patients who died before ten years, and eight hips (eight patients) were revised. Clinical outcome scores were available for 108 hips (104 patients) and radiographs for 103 hips (100 patients). Patients and Methods: A retrospective review was undertaken of a consecutive series of 203 routine primary cemented total hip arthroplasties (THA) in 194 patients. Results: There were no acetabular component revisions for aseptic loosening. Acetabular revision was undertaken in eight hips. In four hips revision was necessitated by periprosthetic femoral fractures, in two hips by recurrent dislocation, in one hip for infection and in one hip for unexplained ongoing pain. Oxford and Harris hip scores demonstrated significant clinical improvement (all p < 0.001). Radiolucent lines were present in 37 (36%) of the 103 acetabular components available for radiological evaluation. In 27 of these, the line was confined to zone 1. No component had migrated. Conclusion: Kaplan–Meier survivorship, with revision for aseptic loosening as the endpoint, was 100% at 12.5 years and for all causes was 97.8% (95% confidence interval 95.6 to 100) when 40 components remained at risk. The Exeter Contemporary flanged cemented acetabular component demonstrates excellent survivorship at 12.5 years. Take home message: The Exeter Contemporary flanged cemented acetabular component has excellent clinical outcomes and survivorship when used with the Exeter stem in total hip arthroplasty.

Bufadienolides. 8. 12(13→14)abeo skeletal rearrangements

Several methods were developed for converting isodigitoxigenin (2a) into methyl acetals 4b and 4c. Of these, methanolysis (followed by acetylation) of isodigitoxigenin in the presence of p-toluenesulfonic acid proved most useful. Each isomer reached an equilibrium corresponding to ca. 3:1 acetal 4c to 4b within 15 min in benzene containing p-toluenesulfonic acid. Addition of dihydropyran to the equilibrium mixture resulted in excellent conversion into vinyl ether 5a. Heating either acetal 4b or 4c in benzene containing p-toluenesulfonic acid led to a skeletal rearrangement culminating in formation of C-norcardenolide 6. In addition to results of physical measurements, the structure of spiran 6 was confirmed by degradation to methyl ketone 8. Similar rearrangement of isodigitoxigenin gave spiran 9 accompanied by C-norcardenolide 6. Treating lactone 9 with p-toluenesulfonic acid in methanol-water provided acetals 10a and 10b, which on further contact with p-toluenesulfonic acid in refluxing benzene gave lactone 9 and cardenolide 6. Evidence underlying the stereochemical assignments noted for structures 4, 9, and 10 was also discussed.

Generation of Cationic Two-Coordinate Group-13 Ligand Systems by Spontaneous Halide Ejection: Remarkably Nucleophile-Resistant (Dimethylamino)borylene Complexes

Spontaneous ejection of chloride from a three-coordinate boron Lewis acid can be effected by employing very electron rich metal substituents and leads to the formation of a sterically unprotected terminal (dimethylamino)borylene complex that has a short metal-boron bond and remarkable resistance to attack by nucleophilic and protic reagents.

Solution cation-binding properties of segmented polyethylene oxide-A C-13 NMR spectroscopic study

Two segmented polyethylene oxides, SPEO-3 and SPEO-4, were prepared using a novel transetherification methodology. Their structures were confirmed by H-1 and C-13 NMR spectroscopy. The complexation of these SPEO's with alkali-metal ions in solution was investigated by C-13 NMR spectroscopy. The mole-fraction method was used to determine the complexation ratio of SPEO with LIClO4 at 25 degrees C, which showed that these formed 1:1 (polymer repeat unit/salt) complexes. The association constant, K, for the complex formation was calculated from the variation of the chemical shift values with salt concentration, using a standard nonlinear least-square fitting procedure. The maximum change in chemical shift (Delta delta) and the K values suggest that both SPEO-3 and SPEO-4 formed stronger complexes with lithium salts than with sodium salts. Unexpectedly, the K values were found to be different, when the variation of delta of different carbons was used in the fitting procedure. This suggests that several possible complexed species may be in equilibrium with the uncomplexed one. Structurally similar model compounds were also prepared and their complexation studies indicated that all of them also formed 1:1 complexes with Li salts. Interestingly, it was observed that the polymers gave higher K values suggesting the formation of more stable complexes in polymers when compared to the model analogues.

Structure, stoichiometry and spectroscopy of oxide superconductors

In the new oxide superconductors, structure and oxygen stoichiometry play the most crucial role. Thus, all the high-temperature oxide superconductors are orthorhombic perovskites with low-dimensional features. Oxygen stoichiometry in YBa2Cu3O7-δ has an important bearing on the structure as well as superconductivity. This is equally true in the La3-xBa3+xCu 6O14+δ system of which only the 123 oxide (x = 1) with the orthorhombic structure shows high Tc. Orthorhombicity though not essential, is generally found ; it is necessary for the formation of twins. The nature of oxygen and copper in the cuprates has been examined by electron spectroscopy. Copper in these cuprates is only in 1 + and 2 + states. It seems likely that oxygen holes are responsible for superconductivity of the cuprates as well as Ba(Bi, Pb)O3. High Tc superconductivity is also found in oxides of the Bi-(Ca, Sr)-Cu-O and related oxides possessing Cu-O sheets.
