Cognitive analytic therapy for borderline erotomania: forensic romances and violence in the therapy room
Authors: Pollock Philip H. 
Published: September 2002

AbstractDysfunctional patterns of attachment have been implicated as substrates for interpersonal violence within relationships, often termed ‘violent attachments’ (Meloy, 1992). Within the therapist–patient relationship, a patient may demonstrate grave complications within the attachment to the therapist, in some cases, manifest as an intense and gross disturbance expressed as obsessive, unrequited affection or love. A lack of reciprocation by the therapist can solicit the patient to pursue, harass or even attack the therapist. A number of mental disorders are encountered in these patients. An illustrative case is presented in which a female patient, who demonstrated one such condition, borderline erotomania, stalked and attempted to kill her therapist, was treated using Cognitive Analytic Therapy (CAT; Ryle, 1990, 1995, 1997). The complications that emerged within the therapeutic relationship are understood through a CAT reformulation and the process of therapy described. The relative benefits of relational models of psychotherapy such as CAT with dysfunctional forms of relating within relationships that can lead to serious interpersonal violence are discussed. Commentary is made regarding clinical threat management for therapists dealing with such cases. Copyright © 2001 John Wiley & Sons, Ltd.
Determination of liquid‐based cervical cytology specimen adequacy using cellular light scatter and flow cytometry
Authors: Grundhoefer Dava , Patterson Bruce K. 
Published: September 2002

AbstractBackground: The majority of cervical cytology specimens are being collected in liquid‐based preservatives (LBP). However, the assessment of specimen adequacy, as mandated by The Bethesda System (TBS), is still being performed at the time of slide review. We present a rapid, flow cytometric method for assessing specimen adequacy. Methods: Three LBPs were compared for cell‐surface antigen preservation. A three‐color antibody panel was used to confirm the light scatter profile of specific cells in a liquid‐based cervical cytology specimen. Using forward and orthogonal light scatter alone, we were able to assess the adequacy of liquid‐based cytology specimens in all LBPs tested. Results: The number of polymorphonuclear neutrophils (PMNs), endocervical (columnar) cells, ectocervical (squamous) cells, and debris in 120 liquid‐based cervical cytology samples was quantified in less than 10 min. Using cutoffs of >20% PMNs, <1.0% endocervical cells, <1.0% ectocervical cells, and <500 total cells per milliliter, light scatter correlated with microscopic determination of adequacy with a correlation coefficient of 0.99. Conclusions: This rapid method allows the quantitative determination of cervical cytology adequacy in liquid‐based cytology preparations prior to the preparation of slides for morphologic assessment.

Performance evaluation of random power capture on mobile communications
Authors: Wen Jyh‐Horng , Hsu Kuo‐Gen , Wen Jet‐Chau , Chen Yi‐Show 
Published: September 2002

AbstractPower assignment schemes are man‐made methods to enhance the capture effect of radio communications. In a previous study, Wen and Yang investigated the combined capture effect of the fixed power assignment scheme, Rayleigh fading, and near–far effect on the performance of packet radios. The performance analysis was limited to an infinite population environment. This assumption is reasonable for a conventional packet radio system with a vast service area. However, for a cellular mobile system, a finite population model should be used. In this paper, we analyse the combined natural and man‐made capture effect on the performance of a cellular system with finite population in each cell. A random power assignment scheme is adopted to produce the man‐made capture. The system throughput and delay are carried out by a Markov model. Some numerical calculations are used to demonstrate the degree of performance improvement. Copyright © 2001 John Wiley & Sons, Ltd.
Interaction between the transmitters ATP and glutamate in the central nervous system
Authors: Illes Peter , Wirkner Kerstin , Nörenberg Wolfgang , Masino Susan A. , Dunwiddie Thomas V. 
Published: September 2002

AbstractAlthough it has been demonstrated repeatedly that ATP is a fast excitatory transmitter in the central nervous system (CNS), there are only limited data to indicate a corelease of ATP with other transmitters such as γ–aminobutyric acid or noradrenaline. Somewhat surprisingly, there is no evidence hitherto for glutamate‐ATP cotransmission in spite of the widespread distribution of glutamatergic neurons in the brain and spinal cord. However, ATPergic and glutamatergic neurons may interact both at the pre‐ and postsynaptic level. Presynaptic P2X receptors facilitate glutamate release both from the terminals of mesencephalic proprioceptive trigeminal neurons projecting to the motor trigeminal nucleus in the brainstem and from primary afferent fibers onto dorsal horn neurons of the spinal cord. The inhibitory effect of ATP via presynaptic P2Y receptors has been demonstrated convincingly at noradrenergic but not glutamatergic nerve terminals. However, in addition to the direct effects of ATP, adenosine formed by the enzymatic degradation of ATP can inhibit the release of glutamate from the Schaffer collateral‐commissural pathway onto CA1 pyramidal cells of the hippocampus. Similarly, ATP degraded to adenosine may inhibit the N‐methyl‐D‐aspartate (NMDA)‐induced current in the striatopallidal subpopulation of medium spiny neurons via A2A receptor activation. Finally, ATP may potentiate the NMDA receptor–mediated depolarization or the underlying inward current at layer V pyramidal neurons of the prefrontal cortex, and P2Y receptors have been suggested to mediate this interaction. Thus, although as a transmitter ATP alters the membrane potential of a limited subset of CNS neurons, it may have widespread and pronounced effects by modulating glutamatergic mechanisms. Drug Dev.

Purinergic modulation of Ca2+ channels and exocytosis in bovine chromaffin cells
Authors: Ulate Guido , Scott Steve Richard , Gilabert Juan Antonio , Artalejo Antonio R. 
Published: September 2002

AbstractIt is now firmly established that adenosine 5′‐triphosphate (ATP) can act as a fast excitatory neurotransmitter by activation of postsynaptic purinergic receptors. Moreover, ATP also serves as a neuromodulator and inhibits neurotransmitter release by acting on presynaptic purinoceptors of the P2Y type. The mechanisms underlying inhibition of neurotransmission by P2Y purinoceptors may involve either inhibition of membrane excitability, particularly Ca2+entry through voltage‐activated Ca2+ channels, or direct action on the secretory apparatus. Bovine chromaffin cells from the adrenal medulla are a good model system to address this problem since: 1) they store and release ATP along with catecholamines by Ca2+ regulated exocytosis; 2) ATP binds to P2Y purinergic receptors to inhibit Ca2+ channels; and 3) they are amenable to combined capacitance measurement and voltage clamp recordings for the purpose of directly examining the relationship between voltage‐activated Ca2+ entry and exocytosis. This paper reviews our recently published results on the specific Ca2+ channel types that are inhibited by ATP and their relative contribution to the expected ATP regulation of catecholamine release from bovine chromaffin cells. While no direct effect of ATP on the secretory machinery could be evidenced, ATP regulation of exocytosis is voltage‐dependent as a reflection of the voltage dependence of ATP effects on Ca2+ channels. These data lend support to the idea of an ATP‐mediated autocrine regulation of secretion from chromaffin cells, though feed‐back regulation of the rate of release can be assumed to be a complex function of the occupancy of the purinoceptors and the electrical and secretory activity of the cell.

Effects of retinoic acid upon eye field morphogenesis and differentiation
Authors: Eagleson Gerald W. , Johnson‐Meeter Leanne J. , Frideres Jennifer 
Published: September 2002

AbstractThis study describes a whole embryo and embryonic field analysis of retinoic acid's (RA) effects upon Xenopus laevis forebrain development and differentiation. By using in situ and immunohistochemical analysis of pax6, Xbf1, and tyrosine hydroxylase (TH), gene expression during eye field, telencephalon field, and retinal development was followed with and without RA treatment. These studies indicated that RA has strong effects upon embryonic eye and telencephalon field development with greater effects upon the ventral development of these organ fields. The specification and determination of separate eye primordia occurred at stage‐16 when the prechordal plate reaches its most anterior aspect in Xenopus laevis. Differentiation of the dopaminergic cells within the retina was also affected in a distinct dorsoventral pattern by RA treatment, and cell type differentiation in the absence of distinct retinal laminae was also observed. It was concluded that early RA treatments affected organ field patterning by suppression of the upstream elements required for organ field development, and RA's effects upon cellular differentiation occur downstream to these organ determinants' expression within a distinct dorsoventral pattern. © 2001 Wiley‐Liss, Inc.
Numerical analysis of heat transfer from transferred‐type plasma to water‐cooled copper anode
Authors: Furukawa Shizue , Amakawa Tadashi , Adachi Kazuo 
Published: September 2002

AbstractA numerical study has been carried out to investigate the effects of gas properties on the mechanism of heat transfer from DC 200A atmospheric pressure arc plasmas to heated materials. We also have performed numerical experiments on “hypothetical” gases while varying their physical properties. These calculation results show that the total amount of heat transfer from nitrogen plasma is greater than that from argon plasma, agreeing with the tendency of experimental results. The main reason for this is efficient conduction heating owing to the plasma's high thermal conductivity and specific heat. In view of the gas properties, it was concluded that the choice of a gas which has both high thermal conductivity and specific heat is beneficial for a policy of greater heat transfer. Nitrogen is one of the most hopeful gases. © 2001 Scripta Technica, Electr Eng Jpn, 136(3): 1–9, 2001
The stability of voltage oscillation modes in longitudinal power systems with SVC
Authors: Kakimoto Naoto , Nagai Takeshi , Nakamura Mitsugu 
Published: September 2002

AbstractIn this paper, we investigate the stability of voltage oscillation modes in longitudinal power systems equipped with static var compensators (SVC). These modes are usually stable, so they do not appear without external force. The conventional harmonic resonance is a phenomenon in which an oscillation mode is excited with a harmonic source. Hence, it is solved by removing the source with a harmonic filter. For this reason, an SVC is equipped with several filters. However, there is a possibility that an oscillation mode itself may become unstable. If a mode is unstable, it can have a large amplitude without any harmonic source. Since it needs no harmonic source, its frequency is not limited to a harmonic frequency, but can have any value. The harmonic instability in direct‐current transmission systems is an example of such phenomena. The PLL (phase‐locked loop) is considered to be effective to suppress harmonic instability with an SVC. However, no theoretical reason has been shown as yet. This paper clarifies the effectiveness of PLL based on a stability condition for the voltage oscillation modes. Frequency responses of a thyristor‐controlled reactor (TCR), a component of the SVC, are largely influenced by the presence of the PLL. If a PLL exists, the stability condition is always satisfied, and all modes are stable. Lastly, we perform numerical simulations to show the validity of our investigation. © 2001 Scripta Technica, Electr Eng Jpn, 137(2): 8–17, 2001
High‐power fourth‐harmonic generation of Nd:YAG laser
Authors: Kojima Tetsuo , Konno Susumu , Fujikawa Shuichi , Yasui Koji 
Published: September 2002

AbstractWe have analyzed the relation between the conversion efficiency of CLBO crystals for fourth‐harmonic generation of Nd:YAG lasers and the effect of frequency‐conversion parameters such as the peak intensity, crystal length, and so on. We have found that the conversion efficiency of CLBO crystals is related to the product of the average input intensity and the crystal length. By this theoretical investigation, we have generated 20.5‐W UV output power by fourth‐harmonic generation of a Nd:YAG laser in a CLBO crystal. This value is, to our knowledge, the highest UV power generated in any solid‐state laser. © 2001 Scripta Technica, Electr Eng Jpn, 137(2): 18–25, 2001
Application of a nonlinear system identification method to thermal power plants
Authors: Toyoda Yukihiro , Wada Kiyoshi 
Published: September 2002

AbstractElectric power companies pay attention to the load following capability and economical operation of a thermal power plant with once‐through boilers. However, conventional PID controllers embedded in DCSs cannot always provide the optimum solution for such subjects. To cope with these problems, we discuss a model‐based advanced control system. Prior to study of the advanced control system, we develop a nonlinear system identification method based on the exogeneous variable‐dependent ARX model considering the characteristics of power plant dynamics. We verify its effectiveness through simulation tests by using measurement data collected in field tests and simulation tests with SIMULINK‐based boiler‐turbine dynamic models. © 2001 Scripta Technica, Electr Eng Jpn, 137(2): 26–35, 2001
Design of guidance system for superconducting maglev vehicle using propulsion coils
Authors: Sakamoto Tetsuzo 
Published: September 2002

AbstractSuperconducting magnetically levitated vehicles have guidance coils that produce vehicle guidance forces using a null flux coil connection. However, the resulting forces do not have sufficient damping forces to suppress lateral vibration of the vehicle. Even though the experimental system has some magnitude of damping, it is still unsatisfactory. Moreover, since the guidance forces are very weak at low speeds, the minimum levitating speed is limited. The paper proposes a guidance method using LSM armature coil currents. When the currents are decomposed into the dq frame variables so that the d‐axis is assigned to the field axis, the d‐axis component of the currents generates lateral forces. The lateral forces of the vehicle are formulated, and the guidance force coefficient is defined. In addition, the author presents a design formula for a guidance regulator system that employs a dynamic compensator using a feedback signal of lateral displacement. The calculated results show that the guidance regulator system works as intended. © 2001 Scripta Technica, Electr Eng Jpn, 137(2): 44–51, 2001
ISO 14001 and Federal Facilities (Part 2)
Authors: Ellis Richard A. 
Published: September 2002

AbstractFederal facilities would be expected to have a substantial head start on conformance to ISO 14001. Federal
and agency requirements have typically required a procedural, standardized approach to management, and this is
the heart and soul of the ISO system. This article will discuss the standard, element by element, to suggest
where federal facilities can take advantage of efforts already expended to meet existing requirements. The
elements must be regarded as nodes of a network, however. Facilities considering an environmental management
system, whether ISO 14001 or another alternative, must create an overlying documentation that directs the user
to the location of these nodes and how they relate to each other. © 2001 John Wiley & Sons, Inc.
Risk aversion, disappointment aversion, and futures hedging
Authors: Lien Donald , Wang Yaqin 
Published: September 2002

AbstractThis article examines the effect of disappointment aversion on futures hedging. We incorporated a constant‐absolute‐risk‐aversion (CARA) utility function into the disappointment‐aversion framework of Gul (1991). It is shown that a more disappointment‐averse hedger will choose an optimal futures position closer to the minimum‐variance hedge than will a less‐disappointment‐averse hedger. The effect of disappointment aversion is stronger when the hedger is less risk averse. A small disappointment aversion will cause a near‐risk neutral hedger to take a drastically different position. In addition, a more‐risk‐averse or disappointment‐averse hedger will have a lower reference point. Numerical results indicate that the reference point of a disappointment‐averse hedger tends to be lower than that of a conventional loss‐averse hedger. Consequently, the disappointment‐averse hedger will act more conservatively, not exploiting profitable opportunities as much as the conventional loss averse hedger will. © 2002 John Wiley & Sons, Inc.

Step‐reset options: Design and valuation
Authors: Hsueh L. Paul , Liu Y. Angela 
Published: September 2002

AbstractThis study proposes a new design of reset options in which the option's exercise price adjusts gradually, based on the amount of time the underlying spent beyond prespecified reset levels. Relative to standard reset options, a step‐reset design offers several desirable properties. First of all, it demands a lower option premium but preserves the same desirable reset attribute that appeals to market investors. Second, it overcomes the disturbing problem of delta jump as exhibited in standard reset option, and thus greatly reduces the difficulties in risk management for reset option sellers who hedge dynamically. Moreover, the step‐reset feature makes the option more robust against short‐term price movements of the underlying and removes the pressure of price manipulation often associated with standard reset options.To value this innovative option product, we develop a tree‐based valuation algorithm in this study. Specifically, we parameterize the trinomial tree model to correctly account for the discrete nature of reset monitoring. The use of lattice model gives us the flexibility to price step‐reset options with American exercise right. Finally, to accommodate the path‐dependent exercise price, we introduce a state‐to‐state recursive pricing procedure to properly capture the path‐dependent step‐reset effect and enhance computational efficiency. © 2002 John Wiley & Sons, Inc.

Astroglial permissivity for neuritic outgrowth in neuron–astrocyte cocultures depends on regulation of laminin bioavailability

Published: September 2002

AbstractThe molecular determinants underlying the failure of axons to regenerate in the CNS after injury were studied in an in vitro model of astrogliosis and neuronal coculture. Mechanically lesioned neuron–astrocyte mouse cortical cocultures were treated with antisense glial fibrillary acidic protein (GFAP)‐mRNA in order to inhibit the formation of gliofilaments that occurs in response to injury. This inhibition relieves the blockage of neuron migration and neuritic outgrowth observed after lesion, and migrating neurons reappeared, supported by a laminin‐labeled extracellular network (permissive conditions). We then questioned the relationship between this permissivity and laminin production. Follow‐up studies on the concentration of laminin indicated that, after antisense treatment, the laminin level was increased in the cocultures and was under the control of astrocyte–neuron interactions. The addition of exogenous laminin favored neuronal migration and neurite outgrowth, whereas neutralizing laminin bioavailability with antibodies recognizing the astroglial laminin resulted in an inhibition of both neuronal access to the lesion site and neurite outgrowth, suggesting an active role for laminin in the permissive process. This permissive process could be associated with modulation of extracellular matrix (ECM) molecule degradation by proteinases. Among the latter, matrix metalloproteinases (MMPs) are involved in the breakdown of the ECM component. Our investigation showed a net decrease of the matrix metalloproteinase MMP‐2 expression and activity and an increase of its endogenous inhibitor TIMP‐2 expression. Both proteins associated with permissivity should be involved in the laminin stabilization and cell‐matrix interactions. High levels of laminin and laminin bioavailability, consequent to a reduction in astrogliosis, may be important permissive elements for neuronal migration and neurite outgrowth postlesion.

AbstractObjectivesLimited Australian dementia incidence data are available. This study aimed to identify the incidence of dementia and its subtypes in an Australian community dwelling population.MethodA community dwelling sample of 647 subjects aged ≥75 years at recruitment were followed for a mean period of 3.2 years (range 2.6–4.5 years). The incidence of dementia (measured in person years at risk) was identified for different levels of severity of dementia, Alzheimer's disease and vascular dementia.ResultsIncidence figures were slightly higher than those previously reported. The incidence of dementia and of Alzheimer's disease increased with age but was not affected by gender. The incidence of vascular dementia was not affected by age.ConclusionThis study provides the largest body of data on the incidence of dementia in Australia, indicating a slightly higher incidence of dementia than previous reports. Further Australian data are required to confirm these findings. Copyright © 2001 John Wiley & Sons, Ltd.
Control of semantic interference in episodic memory retrieval is associated with an anterior cingulate‐prefrontal activation pattern

Published: September 2002

AbstractPrefrontal activation is a consistent finding in functional neuroimaging studies of episodic memory retrieval. In the present study we aimed at a further analysis of prefrontal neural systems involved in the executive control of context‐specific properties in episodic memory retrieval using an event‐related fMRI design. Nine subjects were asked to learn two 20‐item word lists that consisted of concrete nouns assigned to four semantic categories. Ten items of both word lists referred to the same semantic category. Subjects were instructed to determine whether nouns displayed in random order corresponded to the first 20‐item target list. The interference evoked by the retrieval of semantically related items of the second list resulted in significantly longer reaction times compared to the noninterference condition. Contrasting the interference against the noninterference retrieval condition demonstrated an activation pattern that comprised a right anterior cingulate and frontal opercular area and a left‐lateralized dorsolateral prefrontal region. Trial averaged time series revealed that the PFC areas were selectively activated at the interference condition and did not respond to the familiarity of learned words. These findings suggest a functionally separable role of prefrontal cortical areas mediating processes associated with the executive control of interfering context information in episodic memory retrieval.
