TL;DR: According to cultural stereotypes, men are more eager for sex than are women; women are more likely to set limits on such activity as discussed by the authors, but not one woman agreed to a sexual liaison.
Abstract: According to cultural stereotypes, men are more eager for sex than are women; women are more likely to set limits on such activity. In this paper, we review the work of theorists who have argued in favor of this proposition and review the interview and correlational data which support this contention. Finally, we report two experimental tests of ihis hypothesis. In these experiments, conducted in 1978 and 1982, male and female confederates of average attractiveness approached potential partners with one of three requests: "Would you go out tonight?" "Will you come over to my apartment?" or "Would you go to bed with me?" The great majority of men were willing to have a sexual liaison with the women who approached them. Women were not. Not one woman agreed to a sexual liaison. Many possible reasons for this marked gender difference were discussed. These studies were run in 1978 and 1982. It has since become important to track how the threat of AIDS is affecting men and women's willingness to date, come to a...

TL;DR: Women can be categorized and stratified according to future fracture risk, and the selection of postmenopausal women for preventive treatments can be guided by measurements of BMC, the best two-site combination is calcaneus and distal radius BMC.
Abstract: In a prospective study of 699 women, 39 new spine fracture cases were observed during a mean follow-up of 3.6 yr. Spine fracture incidence was compared to initial bone mineral content (BMC) of the calcaneus, distal radius, proximal radius, and the lumbar spine. BMC at all four sites was significantly related to spine fracture incidence. Women at -1 s.d. for calcaneal BMC had a sevenfold greater probability of spine fracture than women at +1 s.d.; women at -2 s.d. had a 50-fold greater probability than women at +2 s.d., even after adjustment for the effects of age. Combinations of BMC at two sites further strengthened the relationship to spine fracture; the best two-site combination is calcaneus and distal radius BMC. Thus women can be categorized and stratified according to future fracture risk, and the selection of postmenopausal women for preventive treatments can be guided by measurements of BMC.

TL;DR: It was found that the species that increased their production per unit leaf area in response to increased light did not increase their leaf area per unit wood biomass in Response to low light, and vice versa, and production of proportionately high leaf area may be important for the growth of C. racemosa in low light.
Abstract: In this study we compared the aboveground growth rates of two exotic shrubs (Rhamnus cathartica and Lonicera X bella) and two native shrubs (Cornus racemosa and Prunus serotina) that are important in southern Wisconsin hardwood forests. For all species except P. serotina, aboveground growth rates in an open habitat were greater than in an understory environment. Growth rates differed among species in the open habitat and were significantly correlated with woody production per unit leaf area. All species had greater leaf area per unit wood biomass in the understory than in the open habitat. A comparison of above-ground growth and annual carbon gain suggests much greater respiratory costs in the open habitat, especially for P. serotina. The data from this study were used to examine mechanisms of species response to different light availabilities. We found that the species that increased their production per unit leaf area in response to increased light did not increase their leaf area per unit wood biomass in response to low light, and vice versa. Production of proportionately high leaf area may be important for the growth of C. racemosa in low light.

TL;DR: It is proposed that much of the chemopreventive action of retinoids can be explained by the enhanced junctional communication of growth regulatory signals.
Abstract: Retinoids that cause inhibition of methylcholanthrene-induced neoplastic transformation of C3H/10T1/2 cells enhance gap-junctional communication in carcinogen-initiated cells. Dose-response studies using retinoids of diverse structures and potency demonstrated a good correlation between these two events. Junctional permeability was enhanced by retinol and tetrahydrotetramethylnaphthalenyl propenylbenzoic acid (TTNPB) at concentrations from 10(-10) to 10(-6) M, and by retinoic acid between 10(-8) and 10(-6) M, the same concentrations that inhibited neoplastic transformation. Retinoic acid inhibited permeability at 10(-10) M, at which concentration transformation was enhanced. Retinoids caused similar alteration sin communication in parental 10T1/2 cells. Communication between initiated and 10T1/2 cells was not influenced by TTNPB. The tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA) inhibited junctional communication in initiated cells, in 10T1/2 cells and between these two cell lines. After repeated exposure of 10T1/2 cells to TPA only retinoid-enhanced communication was blocked; in contrast, basal communication became refractory. It is proposed that much of the chemopreventive action of retinoids can be explained by the enhanced junctional communication of growth regulatory signals.

TL;DR: It is concluded that postlarval immigration may be a major mode of colonization at this site and perhaps in soft bottoms generally, following small-scale disturbance, that patch size must be considered in models of benthic colonization and succession, and that interpreting results from colonization studies with raised substrata may be problematic.
Abstract: The dynamics of soft-bottom disturbance mosaics may be strongly influenced by life stages of colonists, disturbance size, and patch isolation. We assessed the effects of postlarval immigration, patch size, and vertical isolation on colonization following small-scale disturbance in a mudflat in Barnstable Harbor, Massachusetts. Defaunated sediment plugs of two sizes (50 and 1,750 cm2 in plan area) and two levels of isolation (flush with the seafloor and elevated 5 cm) were implanted in the flat and sampled after 4-41 d. Postlarval immigration proved a major colonization mode for both treatment sizes. Colonization rates and successional patterns varied markedly between patch sizes, however. Fauna1 abundance and species number increased more rapidly, and species proportions differed, in smaller treatments primarily because the contribution of postlarval immigration varied inversely with patch size. Colonization in elevated plugs bore little resemblance to that in flush treatments, with macrofauna accumulating in raised plugs at markedly lower rates. We conclude that postlarval immigration may be a major mode of colonization at our site and perhaps in soft bottoms generally, following small-scale disturbance, that patch size must be considered in models of benthic colonization and succession, and that interpreting results from colonization studies with raised substrata may be problematic.

TL;DR: To better define the prevalence of diastolic dysfunction in CHF and to gauge its association with advancing age and other clinical characteristics, a retrospective review of the echocardiographic findings of patients with CHF admitted to the authors' institution is made.
Abstract: Noninvasive cardiovascular imaging techniques such as echocardiography have provided a better understanding of systolic and diastolic function in patients with congestive heart failure (CHF).1,2 The association of diastolic dysfunction with CHF has been recognized in a variety of conditions including restrictive cardiomyopathy, asymmetric septal hypertrophy and hypertensive cardiomyopathy. Diastolic filling abnormalities, however, are not limited to these diseases and are more common than previously thought.3 Moreover, diastolic dysfunction has important therapeutic and prognostic implications. Accordingly, recognition of diastolic dysfunction is necessary for optimal therapy of patients with CHF. To better define the prevalence of diastolic dysfunction in CHF and to gauge its association with advancing age and other clinical characteristics, we made a retrospective review of the echocardiographic findings of patients with CHF admitted to our institution.

TL;DR: Differences observed in the rate of development were sufficient to alter postmortem interval estimates based on larval development in decomposing human tissues by up to 24 h.
Abstract: Larvae of the flesh fly, Boettcherisca peregrina (Robineau-Desvoidy), were reared on the tissue of rabbits to study the effects of cocaine and benzoylecognine on development rates. The rabbits were given 35, 69, and 137 mg of cocaine through cardiac puncture. From hours 30 to 70, larvae developed more rapidly on tissue containing cocaine, benzoylecognine, or both, from rabbits injected with 69 and 137 mg of cocaine than on tissue from rabbits injected with 35 mg of cocaine or no cocaine. Total development times required for pupation and adult eclosion were shortened correspondingly. Differences observed in the rate of development were sufficient to alter postmortem interval estimates based on larval development in decomposing human tissues by up to 24 h.

TL;DR: Malathion poisoning was suspected in a case in which the remains were in an advanced stage of decomposition and the presence of malathion was confirmed by analyses of gastric content and body fat.
Abstract: Deaths as a result of organophosphate poisoning are usually detected by analysis of body fluids and tissues for the presence of the toxic agent. These procedures present particular difficulties when performed on remains in an advanced stage of decomposition. Malathion poisoning was suspected in a case in which the remains were in an advanced stage of decomposition and the presence of malathion was confirmed by analyses of gastric content and body fat. Two species of fly larvae, Chrysomya megacephala (Fabricius) and Chrysomya rufifacies (Macquart), were present on the remains. A sample of these larvae was analyzed for malathion content. A total of 574 μg of malathion was detected in 0.26 g of pooled larvae, or a level corresponding to 2050 μg/g of larvae. Presence of organophosphates in arthropod larvae has not been documented previously and the analysis of larvae from decomposing remains may prove a useful technique for detection of these toxicants in decomposing remains.

TL;DR: In this paper, a 220 km2 area of unusually high reflectivity on the East Pacific Rise (EPR) near lat 8°S is interpreted to be a recently erupted lava field.
Abstract: SeaMARC II records show a 220 km2 area of unusually high reflectivity on the East Pacific Rise (EPR) near lat 8°S which we interpret to be a recently erupted lava field. This is the only segment of the EPR exhibiting high reflectivity over such a large area in our continuous SeaMARC II coverage from lat 8°N to 18°N and 3°S to 23°S. The lavas appear to issue from the axial neovolcanic zone between lat 8°15′ and 8°17′S. The lava field extends up to 18km off-axis and inundates scarps up to 100 m high. On the basis of measurements of scarp heights just outside areas where they are buried, we estimate the average thickness of the field to be 70 ±20 m. Thus, the volume of the lava field is 15 ±4 km3. In comparison, the average annual volcanic budget for the Earth is approximately 4-5 km3, and the largest historic basaltic eruption (from the Icelandic Laki fissure in 1783) was approximately 12.3 km3. When did the eruption occur? Comparative studies of acoustic reflectivity and photographed bottom characteristics elsewhere along the EPR suggest that the lava field has little or no sediment cover and is very young. This is also one of the only areas on the EPR where earthquakes occur that do not appear to be caused by transform faulting. If the earthquakes are related to the lava field, then major eruptions may have occurred in 1964, 1965, and 1969. A large helium plume near lat 13°S may be caused in part by eruptions of the lat 8°S lava field. This is consistent with estimates of currents at 2-3 km depth, which are such that a plume generated at lat 8°S would eventually appear off-axis at lat 13°S. Our observations suggest that this spreading segment, which is bounded by small ridge-axis discontinuities at lat 8°05′S and 8°47′S, may have been the most volcanically active segment along the EPR during the past 25 yr.

TL;DR: Different critical periods for opiate action in different regions of the developing brain could exist, and differential maturity of receptors in these regions could be a factor in such differential drug effects.
Abstract: Perinatal morphine administration affects neuronal growth in the developing animal. Neuronal packing density was reduced by morphine treatment in both primary somatosensory cortex and preoptic area of the hypothalamus. However, glial packing density was increased, but only in hypothalamus, which could reflect greater severity of opiate-induced neurotoxicity in hypothalamus. Cortical pyramidal neurons show morphine-induced reduction of basilar dendritic growth limited to late-developing terminal branches. This effect is completely reversed by concurrent naltrexone administration. This selective effect could be caused by morphine acting at opiate receptors to inhibit extrinsic determinants of dendritic growth (e.g., afferent supply). The ontogeny of opiate receptors is also affected by perinatal morphine administration in a regionally-dependent manner. Mureceptors are downregulated by morphine in hypothalamus, but not in cortex. Differential maturity of receptors in these regions could be a factor in such differential drug effects. Therefore, different critical periods for opiate action in different regions of the developing brain could exist.

TL;DR: The spatial gradient and the time rate of change of brightness over the whole image are exploited and the constraint that the surface of an object in the scene must be in front of the camera for it to be imaged is imposed.
Abstract: We address the problem of recovering the motion of a monocular observer relative to a rigid scene. We do not make any assumptions about the shapes of the surfaces in the scene, nor do we use estimates of the optical flow or point correspondences. Instead, we exploit the spatial gradient and the time rate of change of brightness over the whole image and explicitly impose the constraint that the surface of an object in the scene must be in front of the camera for it to be imaged.

TL;DR: Scanning electron microscopy was used to elucidate the morphology and sequential movement of thrips feeding structures in the 2 species, Frankliniella occidentalis and F. schultzei, and suggests that thrips be classified as piercing-sucking rather than rasping-sucker insects.
Abstract: Scanning electron microscopy was used to elucidate the morphology and sequential movement of thrips feeding structures in the 2 species, Frankliniella occidentalis and F. schultzei, (Thysanoptera : Thripidae). The mouthcone consists of paired paraglossae, and fringed labral pad, a single, apically fused mandible and a pair of interlocking maxillae. The maxillae are open apically and form a feeding tube. Ten pairs of sensory pegs of 3 distinct morphological types (sensilla basiconica with a cuticular collar, sensilla basiconica without a cuticular collar, and sensilla trichoidea) were found on the paraglossae. The possible function of these sensory structures in host finding and choice are discussed. No structure for rasping the leaf's surface was found on the mouthcone or the ventral surface of the insect. Live specimens were observed feeding through Parafilm on artificial media (sucrose solution) and lettuce leaf tissue. These observations support earlier findings that thrips feed by piercing leaf cells with the mandible and ingesting cell contents through the feeding tube formed by the maxillary stylets. Based on these findings, we suggest that thrips be classified as piercing-sucking rather than rasping-sucking insects.

TL;DR: The results suggest that R. reniformis is well-adapted to its environment and emphasize the importance of natural dehydration regimes for assessing anhydrobiotic potential.
Abstract: Induction of anhydrobiosis in the nematode Rotylenchulus reniformis (Linford & Oliveira) was studied using direct exposure to elevated relative humidities and conditions resembling natural dehydration regimes. All larvae and preadults were unable to survive direct short-term exposure to 97% relative humidity. However, dehydration of larvae on model substrates (0.5% agar: 1.0% agarose) that mimic the natural rate of soil moisture loss induced coiling and successful entry into anhydrobiosis. Coiling was maximized at 10–12 days and only coiled larvae survived dehydration, emerging as the preadult form. Larvae could withstand severe dehydration at 80 and 40% relative humidity after the induction of coiling, but were unable to withstand direct exposure to 0% relative humidity. The levels of adaptation utilized by anhydrobiotes to ensure slow dehydration and the adaptive significance of this are discussed in relation to the different environments in which these organisms are found. The results suggest that R. reniformis is well-adapted to its environment and emphasize the importance of natural dehydration regimes for assessing anhydrobiotic potential.

TL;DR: In this article, a specially designed geographic information system was used to create ground-water contamination likelihood maps for a 1500 km2 area and a tentative approach for using this method for monitoring and registration of pesticides is also discussed.
Abstract: Groundwater contamination by agricultural chemicals is a major environmental pollution issue nation-wide. The regulatory agencies of towns and counties face the problem of finding a methodology for assessing the ground-water contamination potential of a large number of agricultural pesticides. Because of the spatial nature of the problem and the limited data availability for comprehensive pesticide movement models, a contamination potential index was employed for preliminary assessment. A specially designed geographic information system was used to create ground-water contamination likelihood maps for a 1500 km2 area. The results suggest that this methodology can be used successfully for evaluating the relative contamination potential of a large number of pesticides over large areas with limited input data. A tentative approach for using this method for monitoring and registration of pesticides is also discussed.

TL;DR: This paper examined the effect of probing for additional information on the accuracy of deception detection and found that probing produced a number of changes in nonverbal behavior, several of which differed between deceivers and truthtellers.
Abstract: This study examined the effect of probing for additional information on the accuracy of deception detection. One hundred forty-eight experimental interactions were analyzed to see whether deceivers and truthtellers behave differently when probed and whether probing improved deception detection. Probing produced a number of changes in nonverbal behavior, several of which differed between deceivers and truthtellers. Probing may have communicated suspicion or uncertainty; therefore, deceptive sources were motivated to control their nonverbal demeanor to mask deception-related cues and appear truthful. Probing did not improve detection. Instead, probing receivers considered all sources more truthful. It is suggested that suspiciousness and prior knowledge may affect probing's efficacy.

TL;DR: In this article, a systematic study of the electric dipole moment (EDM) of neutron Dn in various models of CP violation has been conducted, and it has been shown that in the standard KM model with three families, the EDM is in the range 1.4 × 10−33 ≤ |Dn| ≤ 1.6 × 10 −31e.cm with 90% confidence.
Abstract: We have made a systematic study of the electric dipole moment (EDM) of neutron Dn in various models of CP violation. We find that (i) in the standard KM model with 3 families, the neutron EDM is in the range 1.4 × 10−33 ≤ |Dn| ≤ 1.6 × 10−31e.cm, (ii) the two Higgs doublet model has approximately the same value of Dn as the standard model, (iii) Dn in the Weinberg model is predicted to satisfy |Dn| > 10−25e.cm, (iv) in a class of left-right symmetric models Dn is of the order of 10−26±1e.cm, (v) in supersymmetric models, Dn is of order 10−22ϕ e.cm with ϕ being the possible phase difference of gluino mass and the gluino-quark-squark mixing matrix, (vi)the strong CP parameter θ is found to be θ < 10−9, using the present experimental limit that |Dn| < 2.6 × 10−25e.cm with 90% confidence.

TL;DR: In this paper, a study was conducted at the University of Hawaii to develop a placement test that would match the curriculum for ESL reading, which revealed serious mismatches between the testing procedures and ESL program.
Abstract: ESL placement testing is commonly conducted at the beginning of students' studies to determine which level of study would be most appropriate. However, serious mismatches can occur between ESL placement results and the actual progress made by students between levels. The present study was conducted at the University of Hawaii to develop a placement test that would match the curriculum for ESL reading. The usual placement procedures were conducted (N = 194), using a well-established instrument to test reading comprehension. The 61 students who placed into our reading course were then retested using the same instrument at the end of the 15-week term. The results were analyzed using classical norm-referenced and criterion-referenced item analyses statistics. When the results of the norm-referenced analyses (item facility and discrimination indexes) were combined with those of the criterion-referenced analyses (particularly the difference index), serious mismatches between the testing procedures and our ESL program were revealed. The combined information from both sets of analyses was used to revise the placement test and to improve the match between the test and our specific reading program.

TL;DR: Analysis of plankton samples taken from January to June 1987 in Kaneohe Bay, Oahu, Hawaiian Islands, with a free-fall plankton net, suggests that typical ichthyoplankton surveys would greatly underestimate the abundances of larvae such as the gobiids.
Abstract: Plankton samples were taken from January to June 1987 in Kaneohe Bay, Oahu, Hawaiian Islands, with a free-fall plankton net, to investigate the fine-scale distribution of larval fishes around coral reefs. Daytime samples indicated that the postflexion larvae of two gobiids (Psilogobius mainlandi and an unidentified species) were significantly more abundant at stations immediately adjacent to reefs (near-reef) than at stations in open water off the reef (off-reef). These postflexion gobiid larvae appeared to be capable of resisting advection and dispersal while remaining in the water column near suitable adult habitats. The larvae of Foa brachygramma (Apogonidae) and Encrasicholina purpurea (Engraulidae) were significantly more abundant at off-reef stations than at near-reef stations. Nighttime samples indicated that the gobiid larvae depend on visual cues to remain near the reef. The horizontal distributions of F. brachygramma and E. purpurea larvae appeared to be related to their vertical positioning. These data suggest that typical ichthyoplankton surveys which do not sample close to adult fish habitats would greatly underestimate the abundances of larvae such as the gobiids.

TL;DR: In this article, a relative motion model for the Pacific and Nazca plates is proposed and the authors show that transform faults with slip rates greater than ∼145 km/m.y. do not currently exist along the East Pacific Rise.
Abstract: Oceanic transform faults with slip rates greater than ∼145 km/m.y. do not currently exist along the East Pacific Rise where sea-floor spreading rates range from 145 to 160 km/m.y. Instead, offsets of the the very fast spreading East Pacific Rise are accommodated by microplates, propogating rifts, or overlapping spreading centers. This suggests that there might be a speed limit above which transform faults do not exist. A physical reason for a speed limit is not known, but it might be related to unstable stress fields near the rifts tips, causing them to episodically propagate and prevent a transform fault from being formed. The spreading rates quoted are from our new (0-0.73 Ma) relative-motion model for the Pacific and Nazca plates.

TL;DR: In this article, a pluralist position is adopted, one that views the teaching of standard English as a second dialect (SESD) as "additive bidialectalism" rather than remediation.
Abstract: Recent attempts to establish English-only public policy and legislation reflect declining support for sociolinguistic diversity in the United States. This trend has important consequences in education, not only for speakers of languages other than English, but also for speakers of minority varieties of English. In this article, assimilationist ideology is rejected as a way of legitimizing the educational experience of language minority groups. Instead, a pluralist position is adopted, one that views the teaching of standard English as a second dialect (SESD) as “additive bidialectalism” rather than remediation. The terms dialect, creole, and standard are discussed with reference to the harmful effects of linguistic prescriptivism. Research in two areas is then reviewed: (a) studies examining differences in varieties and their influence on communication and (b) sociolinguistic work on classroom participation structures involving language minority students. It is concluded that differences in varieties are not trivial and that culturally appropriate modifications to classroom discourse patterns, such as those implemented in a program for Hawaii Creole English-speaking children, are useful models for other SESD settings.

TL;DR: A laboratory study on fresh-frozen human cadaver limbs compared six types of flexor tendon pulley reconstruction in the fingers, finding the Karve reconstruction was most effective at 108.2%, which was significantly different from the other five reconstructions (p less than 0.01).
Abstract: A laboratory study on fresh-frozen human cadaver limbs compared six types of flexor tendon pulley reconstruction in the fingers. The reconstructions used were those described by (1) Bunnell, (2) Karev, (3) Weilby, and (4) Lister, and two types developed by us that have not been previously described. The pulleys were studied in specific configurations to determine their effectiveness in transforming tendon excursion into finger flexion. In each finger, comparison was made between the amount of tendon excursion required for full flexion with an intact pulley system versus the various types of reconstructed pulleys. The ratio of these two values was defined as the mechanical effectiveness of the pulley reconstruction. The Karev reconstruction was most effective at 108.2%, which was significantly different from the other five reconstructions ( p

TL;DR: It is concluded that progesterone and other ovarian products may be delivered to the uterus locally and in the same vessel in the opposite horn or in jugular blood.
Abstract: Concentrations of progesterone in uterine and arterial tissue and in uterine and jugular venous plasma were determined. Blood was collected on Days 4 and 9 postestrus from the jugular vein and the first and last venous branches draining each uterine cornu; uterine tissue and arteries were subsequently collected. Progesterone was greater (p less than 0.05) in the cranial third than in the middle or caudal thirds of the uterine horn adjacent to the corpus luteum (CL)-bearing ovary or in any third of the contralateral horn. Progesterone in uterine arterial segments adjacent to the CL-bearing ovary was higher (p less than 0.05) than in contralateral segments. Progesterone was higher (p less than 0.05) in blood from the first venous branch of the cranial third of the uterine cornu adjacent to the ovary with the CL, than in the last branch of the caudal third, or contralateral horn, or in jugular blood. When oviductal veins were resected on Day 9 postestrus, progesterone in the first vein draining the cranial third of the uterine cornu adjacent to the CL-containing ovary was not different (p greater than 0.05) 48 h after resection than in the same vessel in the opposite horn or in jugular blood. We concluded that progesterone and other ovarian products may be delivered to the uterus locally.
