description: The onset of shear flow turbulence is characterized by turbulent patches bounded by regions of laminar flow. At low Reynolds numbers localized turbulence relaminarises, raising the question of whether it is transient in nature or it becomes sustained at a critical threshold. We present extensive numerical simulations and a detailed statistical analysis of the data, in order to shed light on the sources of the discrepancies present in the literature. The results are in excellent quantitative agreement with recent experiments and show that the turbulent lifetimes increase super-exponentially with Reynolds number. In addition, we provide evidence for a lower bound below which there are no meta-stable characteristics of the transients, i.e. the relaminarisation process is no longer memoryless.

title: Criterion-Related Validity of the Borg Ratings of Perceived Exertion (RPE) Scale : A Meta-Analysis
Creators: name: Chen, Michael J.
Publisher: name: Utah State University
Year: 1998

description: The Borg Ratings of Perceived Exertion (RPE) Scale has proven to be a highly popular instrument in measuring the subjective responses of individuals to a given work or exercise task. Historically, the instrument was designed to correlate highly with the heart rates in young-to-middle-aged men performing various tasks. The body of literature, however, has revealed inconsistencies in the extent of just how strong the relationship is between ratings of perceived exertion and various physiological criterion variables, most notably, heart rate. In addition, most studies have invoked the question of whether the criterion-related validity coefficients derived from the relationship between ratings of perceived exertion and a specified physiological criterion variable are just as valid as those for which the Borg RPE Scale was originally performed. A meta-analysis, therefore, was undertaken to determine the magnitude of the relationship between ratings of perceived exertion scores and each of three commonly used physiological measures or criterion variables: heart rate, blood lactate, and oxygen uptake. Results show that by using Tests of Homogeneity for each physiological criterion variable, the observed sample size-weighted validity coefficients are heterogeneous. The median of the mean sample size-weighted validity coefficients is .574 for heart rate, .561 for blood lactate, and .480 for oxygen uptake. Each study in the meta-analysis was grouped by the study characteristics of subject gender, fitness level, RPE Scale, exercise type, exercise protocol, and study quality. For heart rate, the highest validity coefficients are those in which the subjects are highly fit, the exercise type is fairly unusual, such as swimming, and the subjects are required to maximally exert themselves. For blood lactate, the highest validity coefficients are for females, healthy-inactive subjects, the 15-point RPE Scale, treadmill use, and swimming. For oxygen uptake, the highest validity coefficients between ratings of perceived exertion and oxygen uptake are for swimming. In a meta-analysis of study effects, when the validity coefficients are analyzed by study, the resultant mean validity coefficients are only somewhat higher (ratings of perceived exertion and heart rate, .657; ratings of perceived exertion and blood lactate, .642; ratings of perceived exertion and oxygen uptake, .609) than those obtained using sample size-weighted validity coefficients. Finally, corrections for bias generally resulted in increased validity coefficients and decreased variances.

description: This study deals with the preparation of a novel biomaterial by incorporating the hematite α-Fe2O3 onto crushed leaves of the Washingtonia filifera palm tree in their raw state and in extracted cellulose from the same plant. The incorporation of α-Fe2O3 was accomplished by hydrothermal route at 200 °C. The palm leaves, extracted cellulose, and synthesized products were characterized by thermal analysis (TG) and FT-IR spectroscopy. The latter revealed peaks at 524 and 449 cm−1 for the synthesized material, attributed to vibrational deformation of the inorganic Fe-O bond. In contrast to the TG profile of raw palm leaves, the thermogram of the composite degrades in a single step at 343 °C. This one-step decomposition clearly indicates the chemical modification of our cellulose matrix and confirms the successful incorporation of the hematite α-Fe2O3 into the lignocellulose. The second part is devoted to α-Fe2O3 working as sensitizer in photocatalysis, it was characterized optically (Eg= 1.94 eV) and electrochemically with a flat band potential of −0.53 VSCE. The conduction band (−0.73 VSCE) is more cathodic than the potential of the O2/O2•− couple (−0.52 VSCE) and should reduce dissolved oxygen into reactive O2•− radical. The as-prepared materials were successfully tested in the photocatalytic degradation of Rh B (10 ppm) and the result gave an abatement of 60% on α-Fe2O3/lignocellulose under visible light irradiation (LED lamp) with a flux of 23 mW cm−2. The kinetic obeys a first-order model with a half photocatalytic-life of ∼ 7 h.

description: Thrips are major pests in strawberry crops, with control becoming complex due to increasing temperatures, the banning of certain pesticides and growing insecticide resistance. As a global synthesis is lacking, we aimed to: list the interventions tested on strawberries; compare their effectiveness; and identify promising new strategies and research gaps. We conducted a systematic literature review, using Web of Science on October 18, 2024. We included studies monitoring thrips population or damage in strawberries with management interventions. Fifty-nine papers met our criteria, thirty-six of which included a negative control and were included in a meta-analysis. Frankliniella occidentalis (n = 30) and Scirtothrips dorsalis (n = 10) were the most studied species. Biocontrol agents and insecticides were the most common interventions, each assessed in 39 % and 47 % of studies, respectively. Predators were the most promising alternative to insecticides and the effects of 19 such species were observed. Neoseiulus cucumeris, Orius laevigatus and Transeius montdorensis were the most extensively studied. Across studies, predators reduced thrips populations by 51 % to 78 %, compared with 56 % to 79 % using insecticides. Variability between study sites was more significant than between treatments highlighting the importance of other factors, such as climate, not considered in this analysis in the method’s effectiveness. Using tolerant varieties and mass trapping reduced thrips populations by an average of 65 % and 68 %, respectively. However further research is needed. Recent studies also highlighted the importance of early-season population dynamics and surrounding flora on thrips management. Despite progress, more research is required to optimize these strategies.

description: XENON10 is the first two-phase xenon time projection chamber (TPC) developed within the XENON dark matter search program. The TPC, with an active liquid xenon (LXe) mass of about 14 kg, was installed at the Gran Sasso underground laboratory (LNGS) in Italy, and operated for more than one year, with excellent stability and performance. Results from a dark matter search with XENON10 have been published elsewhere. In this paper, we summarize the design and performance of the detector and its subsystems, based on calibration data using sources of gamma-rays and neutrons as well as background and Monte Carlo simulations data. The results on the detector's energy threshold, energy and position resolution, and overall efficiency show a performance that exceeds design specifications, in view of the very low energy threshold achieved (<10 keVr) and the excellent energy resolution achieved by combining the ionization and scintillation signals, detected simultaneously.

description: The study of the physico-chemical modification of Yucca filamentosa (Yf) natural fiber by graft copolymerization with ethylmethacrylate using ferrous ammonium sulfate-potassium persulfate as a redox initiator has been reported in the article. Initially, six process parameters; reaction duration, reaction temperature, solvent amount, pH, FAS:KPS ratio, and monomer concentration were used in the study in a sequential experimental design technique, and the significant process variables affecting the yield of the graft copolymer were identified. The Resolution-V design method identified the significant parameters as the reaction temperature, amount of solvent, and the concentration of monomer. In second phase of the study, the screened variables were utilized in the development of a model through the technique of response surface methodology (RSM) for the prediction of the yields, and its optimization. The developed RSM model fitted well with the experimental data, and predicted for the optimal conditions of reactions as temperature 50 °C, solvent 100 ml, and the monomer 3.05 × 10−3 mol/L; at which the highest graft yield percentage obtained was 124.2%. The techniques of FTIR, SEM, and XRD were used for the characterization graft copolymers. Studies of the various physico-chemical properties showed that the produced graft copolymers were more resistant than the natural fibers.
Phenotypic and functional analysis of antigen presenting cells in a murine model of cutaneous carcinogenesis

Publisher: name: University Of Tasmania

description: To elucidate the nature of the cells involved in the induction of immunosuppression when antigen is applied through Langerhans cell depleted skin, due to prior exposure to 9, 10- dimethyl benzanthracene (DMBA) or 2,4,6-trinitrochlorobenzene (TNCB) the phenotype of migrating antigen bearing cells was analysed. The initial experiments were aimed at the identification of the antigen bearing cells migrating from murine skin previously treated with DMBA or TNCB to deplete Langerhans cells. This involved application of the fluorescent contact sensitiser fluorescein isothiocyanate (FITC) to DMBA or TN.CB treated skin, enrichment of low density cells from draining lymph nodes by metrizamide gradient centrifugation and the phenotypic characterisation of the FITC bearing cells by flow cytometry. Two distinct distinct populations were identified on the basis of FITC fluorescence intensity. These were classified as FITChi or FITCl0. intensities of FITC positive cells were detected in draining lymph nodes of acetone-FITC treated mice. DMBA or TNCB treatment prior to FITC application substantially reduced the number of FITChi cells intensity positive (FITChi) cells within the draining lymph nodes, whereas the number of FIT0¬¨‚àû was slightly reduced This demonstrates that the cells present in DMBA or TNCB treated skin had an impaired ability to trap antigen and migrate to the draining lymph node. Single colour phenotypic analysis of FITC positive cells that did migrate from DMBA or TNCB treated skin revealed populations that expressed markers consistent with dendritic cells, ˜í‚â•˜í¬•-TCR+ cells, CD4+ cells, CD8a+ cells or B cells. Markers for dendritic cells, CD4+ cells and CD8a+ cells were detected upon both FITChi and FITC'0 populations whereas populations of cells expressing ˜í‚â•˜í¬•-TCR and B cell markers were restricted to the FITC'0 population. Both FITChi and FITCl0 populations expressed accessory and adhesion molecules at levels consistent with phenotypically mature dendritic cells. Further analysis of the FITC bearing populations by multiple colour flow cytometry revealed that FITChi cells consisted primarily of mature dendritic cells, while the FITCl0 population was more heterogenous. FITCl0 cells expressed CD11c, CD11b, MHC 11, CD8˜í¬±, CD80 and CD86. Analysis of FITC positive cells revealed FITChi dendritic cells from DMBA-FITC and TNCB¬¨‚â† FITC treated mice were defective in the ability to activate FITC specific responder cells. To determine the identity of the effector population induced by DMBA an in vitro assay was developed. The effector cell was identified as a nylon wool adherent cell, that expressed CD11b. This population was found to act in an antigen nonspecific manner in vitro.
title: Predicting Lumbar Fusion Surgery Outcomes From Presurgical Patient Variables: The Utah Lumbar Fusion Outcome Study
Creators: name: DeBerard, M. Scott
Publisher: name: Utah State University
Year: 1998

description: Lumbar fusion surgery is a commonly used procedure to treat severe spinal pathology and associated chronic disabling low back and leg pain. Despite the common incidence of spinal fusion surgery, few studies have examined patient outcomes or predictive correlates of this procedure. The objectives of this study were to characterize Utah workers who received lumbar fusion surgery in terms of relevant presurgical and outcome variables and to identify presurgical correlates of patient outcomes. An archival prospective research design was utilized consisting of a retrospective medical chart review and a postsurgical telephone outcome survey.
Subjects were 203 workers' compensation patients from the state of Utah who have undergone spinal fusion surgery and who were at least 2 years postsurgery at time of follow-up. Outcomes were assessed for 144 of the 203 patients (71%). Presurgical measures _included demographic, work, compensation, disability, health, surgical, and physiological variables. Outcome measures included solid arthrosis, patient satisfaction, work disability status, functional disability due to back pain, and multidimensional health.
Analysis of patient outcome data revealed that solid arthrosis was achieved in 71.9% of patients. Forty-six percent of subjects felt their back/leg pain problems were worse than what they had expected following the surgery, and 42 % felt that their quality of life had not changed or worsened as a result of lumbar fusion. Twenty-eight percent of fusion patients were work disabled at follow-up. Fusion patient mean outcome scores on multidimensional health measures reflected poorer health than comparative medical patient and nonpatient norms. The most consistent presurgical correlates across outcomes were lawyer involvement, number of prior low back operations, age at injury, and household income at time of injury.
Results are compared to data from previous lumbar fusion research studies and reasons for varying findings are offered. Implications of the findings are discussed in terms of inadequate patient selection and insufficient assessment of patient outcomes in low back research studies. Limitations of the present research are discussed, including how placebo, natural history, and regression to the mean can lead to erroneous conclusions about the efficacy of lumber fusion surgery. Suggestions for improvements in low back surgery outcome research are offered.
Measurement of the profile of He I 4471 Å at low electron densities
Creators: name: Stevenson, Dale Christian
Publisher: name: University of British Columbia
Year: 2011

description: The profiles of the He I lines with forbidden components in plasmas with electron densities below 10¹⁵ electrons per cc. are of astro-physical interest. A pulsed-arc plasma device has been constructed and operated at such initial conditions that in the afterglow (i.e. up to 200 μsec after breakdown), the steadily decreasing electron density passes through the range of interest. The plasma was observed end-on with a monochromator at a wavelength near 4471 angstroms for each discharge, and the intensity recorded as a functions of time. Good shot-to-shot reproducibility of the plasma permitted the line profile to be reconstructed for different times by repeating the measurements at different wavelengths spanning the line. The profile of He I 4471 has been measured for 10¹⁵ cm ̄³ and agreement has been found with the results of Burgess and Cairns (1971) and recent calculations of Barnard and Cooper (to be published).

description: NMR longitudinal relaxation rates 1/T1 and Knight shifts K have been measured for superconducting samples of LaFe1-yCoyAsO1-xFx with y=0.0 and 0.0075 and for a nonsuperconducting metallic sample with y=0.1, where the x values are always fixed at 0.11. The temperature (T) dependence the relaxation rates 1/T1 of the superconducting samples has been found to be markedly different from the behavior 1/T1 T^(2.5-3.0) reported by many groups in the entire T range measured (from the temperature immediately below the superconducting transition temperature Tc down to (0.1-0.2)Tc). The nonexistence of the coherence peak has also been found. Based on the results of the measurements and other kinds of existing data, arguments are presented on the superconducting symmetry of the Fe pnictide systems, where the several points which cannot be easily understood by existing theories, are pointed out. Results of the measurements on the nonsuperconducting metallic samples are also presented.

Publisher: name: University of British Columbia
Year: 2011

description: A variation of the classical canal ray source has been developed for the study of the Stark Effect in positive ion lines. Stress was placed on the measurement of small line shifts rather than the attainment of large electric fields. To this end a sensitive shift measuring apparatus employing a linear neutral density filter to translate the line shift into a change in intensity was built. Shifts were measured to an accuracy of about .02 A° in the following lines: He I 5016 A°, 7281 A°, 6678 A°, 3889 A° and Ar I 4272 A°, 4266 A°. No shifts were detected in Ar II 4727 A° and 4806 A°. A discussion of prospective improvements to be made in the apparatus is also included. With these improvements, the apparatus should be capable of measuring shifts to an accuracy of .001 A°.
title: Exploring the mechanistic rationale of plant-pollinator communication disruption by ozone
Creators: name: Alkan, Matthew Kaan
Publisher: name: University of Reading
Year: 2023

description: In recent years pollinator populations have been declining worldwide, while concurrently tropospheric ozone concentrations have been increasing. It has been shown that plant-pollinator communication is partially mediated by volatile organic compound (VOC) based communication and this communication method is susceptible to perturbation as a result of ozone exposure. However, to date, no single study has investigated the individual mechanisms that cause the perturbation of VOC based communication in isolation of each other. This thesis tested and or modelled the effect of several of these mechanisms on the antennal electrophysiological responsesof Apis melliferain isolation, namely:i)VOC blend ratio alteration, ii)VOC degradation product formation, and iii)Secondary organic aerosol (SOA) formation.Testing and/or modelling was conductedunder two landscape-scale scenarios, applyinga literature derived average foraging distance for A. melliferaof 400mwhen undertaking comparisons.Modellingdemonstrated that, under these modelling parameters,alterations inVOC blend ratioas a result of ozone pollution maycauselarge changesin electrophysiological response for some compounds with minor changes for others.Several VOC degradation products were identified and elicited statistically significant electrophysiological antennal responses. Whileit was demonstrated that each of the VOCs tested was capable of forming SOA as a result of their reaction with ozone,exposure of A. melliferaantennaeto SOAdid not cause a statistically significant change in antennal electrophysiological response to two stimuli during or after SOA exposure. It was also observed that any effects of these mechanisms were likely to be greater under an ozone excess landscape scenario which may be akin to a small group of flowers in an open landscape. This work has not only shown the potential of differing mechanisms to contribute to VOC communication perturbation, thus allowing for the synthesis of further work to characterise the most at-risk plant-pollinator interactions but has also highlighted the effect that landscape may have on these interactions.

description: We consider a model of bilayer lipid membrane with bola-lipids. The bola-lipid is modeled by linking tails of the hydrophobic chains in the opposite monolayers within bilayer as a first approximation. A number of thermodynamical characteristics are calculated analytically and compared with the ones of a regular membrane without chains linkage. Pronounced difference between lateral pressure profiles at the layers interface for linked and regular bilayer models is found. In the linked case, the lateral pressure mid-plane peak disappears, while the free energy per chain increases. We have also calculated distribution of the orientaional order parameter of linked chains across the bilayer, and found it is in contrast with the usual lipids case.

Interaction patterns in the families of children with idiopathic epilepsy
Creators: name: Ritchie, Karen Anne
Publisher: name: University Of Tasmania
Year: 2023

description: Behaviour disturbances in epileptic children are currently recognised to be a function of a complex interaction of physiological and environmental factors. In cases of idiopathic epilepsy, family attitudes and behaviour have been consistently demonstrated to be the most significant causal antecedents of deviant behaviour. However, this conclusion has been based almost entirely on techniques designed to demonstrate psychological abnormalities in the parents of epileptic children. Consequently, theories derived from this research are inadequate due to their reliance on the outmoded conceptualisation of behaviour as a function of immutable personality traits, and also due to their failure to indicate therapeutic guide-lines. The present study proposed an alternative model of the effects of family behaviour on the adjustment of epileptic children, based on family interaction and social learning theories. The behaviour of epileptic member families was conceptualised as the adaptive reaction of an interdependent group to a crisis situation, leading to alterations in the behaviour of the epileptic child in the direction of conformity with the group. The study employed a semi-structured interview and videotaped observations of family interaction, initiated by means of the Revealed Differences Technique. Thirty family tetrads were studied, consisting of the parents, and two children aged between 8 and 16 years. Of these, fifteen contained an epileptic elder child and the other fifteen served as a control group matched for socio-economic status, religion, nationality, occupational status of the mother, and the age, sex and birth order of the siblings. Analysis of the family interaction sequences demonstrated that epileptic-member families formed rigid hierarchical units with increased efficiency in problem-solving. The mother emerged as a strong family leader. The epileptic child was observed to take a position of reduced involvement in family interaction and to actively withdraw from family decision making. The results support crisis theories of family behaviour which maintain that in situations where family integrity is threatened, a more stable and secure system of family organisation is adopted. The cross-sectional design of the study did not permit the demonstration of a causal relationship between family behaviour and the onset of behaviour disturbance in the epileptic child. However, it demonstrated in functional, behavioural terms, important differences between epileptic-member and normal families which strongly support such a casual relationsh1p and stressed, therefore, the need for further research in this area. The clinical value of the present study is discussed in terms of the guide-lines these results offer for clinical intervention techniques based on social learning theory.

description: The degree of intermittency of the magnetic field of a large-scale dynamo is considered. Based on simulations it is argued that there is a tendency for the field to become more diffuse and non-intermittent as the dynamo saturates. The simulations are idealized in that the turbulence is strongly helical and shear is strong, so the tendency for the field to become more diffuse is somewhat exaggerated. Earlier results concerning the effects of magnetic buoyancy are discussed. It is emphasized that the resulting magnetic buoyancy is weak compared with the stronger effects of simultaneous downward pumping. These findings are used to support the notion that the solar dynamo might operate in a distributed fashion where the near-surface shear layer could play an important role.

description: In April 2019, Algerian voters will go to the polls to elect their next president. Abdelaziz Bouteflika, the incumbent president, is the ruling FLN designated candidate for the elections. Bouteflika, who was first elected in 1999 and is the longest-serving Algerian head of state, has yet to announce his candidacy. However, for the moment the only obstacle to his re-election seems to be his advanced age and deteriorating health: the other candidates pose no threat and reflect the non-existence of any real opposition. Therefore, the question is not whether Bouteflika will be re-elected but what will happen afterwards. If he is still considered to be the father of the Reconciliation and represents a system whose longevity is based on its ability to adapt to changing circumstances, the regime will be unable to buy time and stall implementing change. Moreover, unless the Constitution is amended the 2019–2024 mandate will be Bouteflika’s last. Therefore, in the longer term a change in leadership will be imperative, at least from a political perspective.

Chaos in KdV-like equations

Publisher: name: University Of Tasmania

description: The correspondence between soliton solutions of nonlinear partial differential equations and homoclinic orbits in appropriately chosen phase spaces of these equations is well-known. Perturbations of homoclinic orbits can be studied by use of the Melnikov technique; this focusses on the splitting of such orbits into stable and unstable invariant manifolds and explains the emergence of chaotic phenomena via Smale horseshoes. In this thesis the Melnikov method is applied to the homoclinic orbits corresponding to solitons of the Korteweg-de Vries (KdV) and modified Korteweg-de Vries (MKdV) equations. These equations are reduced to third order ordinary differential equations by a travelling wave ansatz, defining a three-dimensional phase space of the equivalent systems of three first order equations. The geometry of periodic and homoclinic orbits and their structural changes under perturbations is investigated. It turns out that the three dimensional phase spaces foliate into a continuous family of invariant two-dimensional subspaces. By integrating the equations to second order the analysis by Melnikov's method is restricted to these subspaces and is considerably simplified. The Melnikov integrals stemming from the periodic and dissipative part of the perturbations, determining the onset of chaos, are then evaluated for the reduced KdV and MKdV systems. They are used to calculate the critical ratios between perturbation amplitude and dissipation coefficient at which tangency between table and unstable manifolds occur. At these critical ratios the transition/bifurcation from regular to chaotic behaviour occurs. It is observed that the Melnikov function for the periodic perturbation of the MKdV case vanishes for certain perturbation frequencies and parameter values, as confirmed by numerical work. The apparent discrepancy between structurally unstable homoclinic orbits and stable solitons is discussed and it is shown that solitons can persist despite the splitting of their corresponding homoclinic orbits under perturbation. Finally, subharmonics and resonance for the periodic solutions under perturbations are investigated using fourth order averaging techniques applied over the solution periods, which reveals a period doubling bifurcation in the subharmonics.
ATG14L and ZBTB16: Critical Roles in Aggrephagy in STHdhQ7/Q7 Striatal Neurons

description: Huntington’s disease (HD) is a devastating neurodegenerative disease caused by a polyglutamine expansion repeat in exon one of the gene encoding the huntingtin protein. A hallmark of HD pathology is the accumulation of aggregates of the mutant huntingtin protein (mHtt). Macroautophagy (MA) is an intracellular catabolic process responsible for the degradation of cytoplasmic constituents, including misfolded protein aggregates, as are found in HD. Selective MA which degrades protein aggregates is known as aggrephagy. Recently, chronic blockade of the metabotropic glutamate receptor subtype 5 (mGluR5) in the zQ175 HD mouse model has been shown to cause an improvement in disease progression, which correlated with an activation of the GSK3-mediated pathway of MA. A reduction in ZBTB16, a core component of the ZBTB16-Cullin3-Roc1 E3 ubiquitin ligase complex, and an increase in ATG14L, a key component of the vps34 complex responsible for autophagosome biogenesis, were evident following mGluR5 inhibition in zQ175 HD mice. In the present study, we have found that silencing of ATG14L using CRISPR Cas9 in STHdhQ7/Q7 striatal neurons causes an inhibition of MA, a unique post-translational modification on beclin-1, decreased mGluR5 expression, and the accumulation of Q138 (mHtt). We find that CRISPR-Cas9-induced silencing of ZBTB16 in STHdhQ7/Q7 striatal neurons causes an induction of MA, decreased mGluR5 expression, and the clearance of Q138 (mHtt). ZBTB16 likely exerts its effects on MA via regulation of ATG14L. These findings elucidate the important role of ATG14L and ZBTB16 in aggrephagy in STHdhQ7/Q7 striatal neurons, and suggest that the modulation of ATG14L and ZBTB16 may represent novel therapeutic approaches in the treatment of HD.

description: This was a descriptive study that examined the relation between domestic violence and pct abuse. Participants were questioned about their styles of conflict resolution with partners and how pets were treated in the home. Information was gathered using the Conflict Tactics Scale, and three surveys were developed for this study: the Battered Partner Shelter Survey, Families and Pets Survey, and the Child 's Observations and Experience with Pets. Four groups were recruited: (a) women in crisis shelters who chose to include one of their children in the study (.n = 39), (b) women in crisis shelters who did not include one of their children in the study (n = 62), (c) women who had not been subjected to domestic violence and chose to share information about one of their children (.n = 30), and (d) women who had not been subjected to domestic violence and did not provide information about one of their children (.n = 30). Mothers who chose to include one of their children in the study completed a Child Behavior Checklist (CBCL) for that child. Five shelters in the state of Utah--Logan, Brigham City, Ogden, Salt Lake City, and Provo--were included. Data collection in the shelters occurred over 17 months. Participants in the comparison group were recruited via newspaper advertisements in the Herald Journal in Logan.
Analyses of the data confirmed the coexistence of domestic violence and pet abuse . The results revealed that the severity of threats and abuse toward pets, and the severity of violent means of interpartner conflict resolution escalate in a parallel manner . However , many of the male partners who become violent toward women have a history of pet abuse that precedes their relationship with the woman. This study increased awareness of the coexistence of these two types of violence both as it was run and as a source for future professional presentations. The importance of this study and implications for future research are discussed.

description: We discuss consistent power counting for integrating soft and collinear degrees of freedom over arbitrary regions of phase space in the soft-collinear effective theory (SCET), and illustrate our results at one loop with several jet algorithms: JADE, Sterman-Weinberg and k_T. Consistently applying SCET power-counting in phase space, along with non-trivial zero-bin subtractions, prevents double-counting of final states. The resulting phase-space integrals over soft and collinear regions are individually ultraviolet divergent, but the phase-space ultraviolet divergences cancel in the sum. Whether the soft and collinear contributions are individually infrared safe depends on the jet definition. We show that while this is true at one loop for JADE and Sterman-Weinberg, the k_T algorithm does not factorize into individually infrared safe soft and collinear pieces in dimensional regularization. We point out that this statement depends on the ultraviolet regulator, and that in a cutoff scheme the soft functions are infrared safe.

description: Persönlichkeitsmodelle spielen für das ätiologische Verständnis von abweichender Entwicklung im klinischen Alltag eine wichtige Rolle. In diesem Überblicksartikel werden relevante Persönlichkeitsmodelle vorgestellt und insbesondere hinsichtlich ihrer Entwicklungsdynamik und ihrer Bedeutung für die Adaptationsfähigkeit über die Lebensspanne, beginnend in der Kindheit näher beleuchtet. Im Fokus steht dabei die entwicklungspsychopathologische Bedeutung von Prozessen der Ich-Flexibilität und Selbstregulationsfähigkeit im Spannungsfeld zwischen Disposition und sozialen Umgebungsbedingungen. Dies zeigt sich gerade in der Diskussion von Entwicklungspfadmodellen zu Persönlichkeitsfehlentwicklungen mit Misshandlungserleben bzw. Bindungsdesorganisation in der kindlichen Vorgeschichte. Psychopathologisch ergeben sich aus einer persönlichkeitsimmanenten Beeinträchtigung der Selbststeuerungsfähigkeit häufig stabile Fehlanpassungsmuster, die bei rein symptomatischer Behandlung meist nur zu temporären Verhaltensmodifikationen führen. Hingegen spricht die Veränderbarkeit pathologischer Persönlichkeitszüge durch den Einsatz gezielter Interventionsansätze für eine positive Entwicklungsmöglichkeit und widerspricht einer deterministischen Merkmalsstabilität. Für künftige entwicklungspsychopathologische Forschungsperspektiven werden verschiedene theoretische Persönlichkeitskonstrukte mit klinischen Beobachtungen in Verbindung gebracht und diskutiert.
