The Impact of Sexual Boundary Violations in Supervision and Therapy: A Qualitative Study of a Trainee's First-Hand Account

This study involves a qualitative analysis of a doctoral-level psychology trainee's first-hand account of sexual attraction and boundary violations that occurred in her clinical supervision and psychotherapy. Concepts of power, gender, social performance theory, and relational framing are applied to two case examples, illustrating the differing demands on a trainee when her relationships were sexualized in two distinct professional contexts. Ramifications of supervisory exploitation and the impact of such an experience on a trainee's professional development are discussed. Recommendations are provided for improving psychology training programs' prevention and response efforts.

Geodynamic implications derived from Numidian-like distal turbidites deposited along the Internal–External Domain Boundary of the Betic Cordillera (S Spain)

New data reveal Early Burdigalian ‘Numidian-like lithofacies’ in successions of the internal (southernmost) part of the South Iberian Margin (SIM) and the south-western margin of the Mesomediterranean Microplate (MM). The well-known Numidian Formation was deposited in the external (Massylian) sub-domain of the Maghrebian Flysch Basin (a south-western branch of the Tethys Ocean). The anomalous occurrence of ‘Numidian-like lithofacies’ is induced by the particular Early Miocene palaeogeographical and geodynamic complexity of the sector. This consisted of a ‘triple point’ with a dextral transform fault between the SIM and the MM-Maghrebian Flysch Basin system. In this framework, the ageing of Iberian reliefs and the MM collapse, coupled with an African Margin upbulging, and a shortening of the Maghrebian Flysch Basin (both related to the subduction), could have resulted in the arrival of the Numidian depositional system from so far away.

Propagation of Dyakonon Wave-Packets at the Boundary of Metallodielectric Lattices

We rigorously analyze the propagation of localized surface waves that takes place at the boundary between a semi-infinite layered metal-dielectric (MD) nanostructure cut normally to the layers and a isotropic medium. It is demonstrated that Dyakonov-like surface waves (also coined dyakonons) with hybrid polarization may propagate in a wide angular range. As a consequence, dyakonon-based wave-packets (DWPs) may feature sub-wavelength beamwidths. Due to the hyperbolic-dispersion regime in plasmonic crystals, supported DWPs are still in the canalization regime. The apparent quadratic beam spreading, however, is driven by dissipation effects in metal.

A new boundary-based morphological model

Mathematical morphology addresses the problem of describing shapes in an n-dimensional space using the concepts of set theory. A series of standardized morphological operations are defined, and they are applied to the shapes to transform them using another shape called the structuring element. In an industrial environment, the process of manufacturing a piece is based on the manipulation of a primitive object via contact with a tool that transforms the object progressively to obtain the desired design. The analogy with the morphological operation of erosion is obvious. Nevertheless, few references about the relation between the morphological operations and the process of design and manufacturing can be found. The non-deterministic nature of classic mathematical morphology makes it very difficult to adapt their basic operations to the dynamics of concepts such as the ordered trajectory. A new geometric model is presented, inspired by the classic morphological paradigm, which can define objects and apply morphological operations that transform these objects. The model specializes in classic morphological operations, providing them with the determinism inherent in dynamic processes that require an order of application, as is the case for designing and manufacturing objects in professional computer-aided design and manufacturing (CAD/CAM) environments. The operators are boundary-based so that only the points in the frontier are handled. As a consequence, the process is more efficient and more suitable for use in CAD/CAM systems.

Implementation of non-local boundary layer schemes in the Regional Atmospheric Modeling System and its impact on simulated mesoscale circulations

This paper proposes the implementation of different non-local Planetary Boundary Layer schemes within the Regional Atmospheric Modeling System (RAMS) model. The two selected PBL parameterizations are the Medium-Range Forecast (MRF) PBL and its updated version, known as the Yonsei University (YSU) PBL. YSU is a first-order scheme that uses non-local eddy diffusivity coefficients to compute turbulent fluxes. It is based on the MRF, and improves it with an explicit treatment of the entrainment. With the aim of evaluating the RAMS results for these PBL parameterizations, a series of numerical simulations have been performed and contrasted with the results obtained using the Mellor and Yamada (MY) scheme, also widely used, and the standard PBL scheme in the RAMS model. The numerical study carried out here is focused on mesoscale circulation events during the summer, as these meteorological situations dominate this season of the year in the Western Mediterranean coast. In addition, the sensitivity of these PBL parameterizations to the initial soil moisture content is also evaluated. The results show a warmer and moister PBL for the YSU scheme compared to both MRF and MY. The model presents as well a tendency to overestimate the observed temperature and to underestimate the observed humidity, considering all PBL schemes and a low initial soil moisture content. In addition, the bias between the model and the observations is significantly reduced moistening the initial soil moisture of the corresponding run. Thus, varying this parameter has a positive effect and improves the simulated results in relation to the observations. However, there is still a significant overestimation of the wind speed over flatter terrain, independently of the PBL scheme and the initial soil moisture used, even though a different degree of accuracy is reproduced by RAMS taking into account the different sensitivity tests.

The Ontario-Manitoba Boundary Dispute

The powers of the General Government are so much greater than those of the United States in its relations with the Local Governments, that the central power must win. The next quarter century was marked by struggle, or rather a series of struggles, between the Dominion Government and those of the various provinces with as a general rule contrary to Macdonal's expectations, the latter proving successful. Ontario was the most consistent opponent of centralizing tendencies; her most notably victory was scored in what is known as the Ontario-Manitoba Boundary Dispute. It is out intention to deal with this question primarily as a phase of post-Confederation politics.

Benthic foraminiferal abundances at the Cretaceous/Paleogene boundary of ODP Hole 117-1049C at Blake Nose, Northwest Atlantic (Appendix A)

Sediments recovered at lower bathyal ODP Site 1049 on Blake Nose (Northwestern Atlantic) offer an opportunity to study environmental changes at the Cretaceous/Paleogene (K/P) boundary relatively close to the Chicxulub impact structure on the Yucatan peninsula, Mexico. In Hole 1049C, the boundary is located at the base of a 9-cm-thick layer with abundant spherules, considered to be impact ejecta. Uppermost Maastrichtian oozes below, and lowermost Danian pelagic oozes above the spherulebed contain well-preserved bathyal benthic foraminifera. The spherule-bed itself, in contrast, contains a mixture of shallow (neritic) and deeper (bathyal) species, and specimens vary strongly in preservation. This assemblage was probably formed by reworking and down-slope transport triggered by the K/P impact. Across the spherule-bed (i.e., the K/P boundary) only ~7% of benthic foraminiferal species became extinct, similar to the low extinction rates of benthic foraminifera worldwide. Quantitative analysis of benthic foraminiferal assemblages and morphogroups in the >63-µm size fraction indicates a relatively eutrophic, stable environment during the latest Maastrichtian, interrupted by a sudden decrease in the food supply to the benthos at the K/P boundary and a decrease in diversity of the faunas, followed by a stepped recovery during the earliest Danian. The recovery was probably linked to the gradual recovery of surface-dwelling primary producers.

Abundance of calcareous nannofossils across the K/T boundary at ODP Hole 113-690C (Table 1)

A biostratigraphically continuous, but intensely bioturbated, Cretaceous/Tertiary boundary sequence was cored during Ocean Drilling Program (ODP) Leg 113 on Maud Rise (65°S) in the Weddell Sea off East Antarctica. This interval is the first recovered by ODP/DSDP in the South Atlantic sector of the Southern Ocean and offers a unique opportunity to study the nannofossil sequences leading up to and beyond the terminal Cretaceous event at a high southern latitude. The K/T boundary lies just within Chron 29R and is placed at ODP Sample 113-690C-15X-4, 41.5 cm. An iridium anomaly was independently noted at about this level as well. Upper Maestrichtian-lower Paleocene sediments consist mostly of light-colored nannofossil chalks. Dark brown sediments at the base of the Danian (Zone CPla) are characterized by an increased clay content attributed to a drop in calcareous microplankton productivity following the terminal Cretaceous event. Although delineation of the boundary is hampered by intense bioturbation, the sharp color contrast between overlying clay-rich, dark brown chalks of the Tertiary and light cream colored chalks of the Cretaceous aids in the selection of the K/T horizon. Several dark colored burrows sampled at intervals as far as 1.3 m below the boundary and within the light colored Cretaceous chalk were found to contain up to 17% Tertiary nannofossils. Calcareous nannofossils from the boundary interval were divided into three groups for quantitative study. The three groups, "Cretaceous," "Tertiary," and "Survivor," exhibit a sequential change across the boundary with the Cretaceous forms giving way to a Survivor-dominated assemblage beginning at the boundary followed shortly thereafter by the appearance of the Tertiary taxa, Cruciplacolithus and Hornibrookina. The species, H. edwardsii, comprises nearly 50% of the assemblage just above the Zone CPla/CPlb boundary, an abundance not reported elsewhere at this level. Calculation of individual species abundances reveals several additional differences between this K/T boundary interval and those studied from middle and low latitude sections. The percentage of Thoracosphaera is much lower at the boundary in this section and a small form, Prediscosphaera stoveri, is extremely abundant in Cretaceous sediments just below the boundary.

Biostratigraphic events close to the Tortonian-Messinian boundary at ODP Hole 107-654A (Table 1)

Correlations of biostratigraphic datums to the geomagnetic reversal time scale (GRTS) at Leg 107 sites provide a means of correlating these datums to sections outside the Mediterranean. Unfortunately, poor recovery and core deformation due to rotary drilling at Sites 651, 652, and 654 severely hampered efforts to acquire detailed magnetostratigraphies and biostratigraphies. However, many biostratigraphic markers could be correlated to the GRTS, including those close to the Miocene/Pliocene and Tortonian/Messinian boundaries. These boundaries are interpreted to occur in Chrons 3r and 3B, respectively (chron nomenclature after Cox, 1982). Comparison of the correlation of Plio-Pleistocene calcareous plankton biostratigraphic events to the GRTS in the Mediterranean and in the open oceans indicates that many events are broadly synchronous between the two environments. The outstanding exception is the first occurrence of Globorotalia margaritae which is delayed in the Mediterranean by about 1 m.y.
