This article explores the work of psychologist Gordon Gallup, Jr., during the 1960s and 1970s on mirror self-recognition in animals. It shows how Gallup tried to integrate the mental "self-concept" into an otherwise strictly behaviorist paradigm. By making an argument from material culture, the article demonstrates how Gallup's adoption of a self-concept is best understood as a product of his sustained analysis of the workings of the mirror as a piece of experimental apparatus. In certain situations, the stimulus properties of the mirror changed dramatically, a shift that Gallup thought legitimated the positing of a self-concept...

In this work, we investigate the ability to control Si nanoparticles (NPs) spatially arranged in a hexagonal network of 20 nm wide nanovolumes at controlled depth within SiO2 thin films. To achieve this goal an unconventional lithographic technique was implemented based on a bottom-up approach, that is fully compatible with the existing semiconductor technology. The method combines ultra-low energy ion beam synthesis with nanostructured block-copolymer thin films that are self-assembled on the SiO2 substrates to form a nanoporous template with hexagonally packed pores...

Cultural categories related to sexuality and gender vary considerably cross-culturally. While Western cultures categorize people primarily in terms of sexual attractions (i.e., gay, straight, bisexual), many cultures distinguish between groups based on additional issues such as gender role presentation and position preference in anal sex (i.e., insertive/receptive). The current study gathered data on three categories of natal males in Mumbai, India-hijra, kothi, and panthi (N = 93). Hijra are androphilic (sexually attracted to adult men), typically sexually receptive, transgender, sometimes castrated, and live in fictive kinship networks that are hierarchically organized...

There has been much recent interest in the use of porous materials derived from self-assembling, shape-persistent organic cages due to their solubility and easy post-synthetic modification. Herein we report the preparation of novel mixed-matrix membranes (MMMs) employing the porous organic cage Noria and its derivatives Noria-Boc and Noria-CO(t)Bu as the fillers, and a fluorine containing polyimide, 6FDA-DAM, as the polymeric matrix. The physical structures and properties of Noria and its derivatives were measured and investigated...

The shift from outcrossing to selfing is often accompanied by striking changes in floral morphology towards a "selfing syndrome", which is characterized by flowers with reduction in size, pollen: ovule (P/O) ratio, and herkogamy. This study aims to test whether such changes have occurred in the North American Arabidopsis lyrata, which is of particular interest because of the relatively recent transitions to selfing in this system. Flower size, flower shape, herkogamy levels, P/O ratio, and floral integration of six self-incompatible (outcrossing) and six self-compatible (selfing) populations of A...

PREMISE OF THE STUDY: Interspecific reproductive barriers (IRBs) often prevent hybridization between closely related species in sympatry. In the tomato clade (Solanum section Lycopersicon), interspecific interactions between natural sympatric populations have not been evaluated previously. In this study, we assessed IRBs between members of the tomato clade from nine sympatric sites in Peru. METHODS: Coflowering was assessed at sympatric sites in Peru. Using previously collected seeds from sympatric sites in Peru, we evaluated premating prezygotic (floral morphology), postmating prezygotic (pollen-tube growth), and postzygotic barriers (fruit and seed development) between sympatric species in common gardens...

A process evaluation was conducted in conjunction with a controlled trial of a self-directed exercise program among people with arthritis to describe the program's reach; self-management behaviors, exposure to materials, program perceptions, satisfaction, and perceived benefits; compatibility with targeted participants' needs; and maintenance. Participants (n=197) were predominantly white, middle-aged, college-educated women. At 12 weeks, 73.2% had read ≥90% of the program materials (at nine months>70% had "occasionally" or "often" looked back over each of the five parts of the materials); 63...

Plants have mechanisms to recognize and reject pollen from other species. Although widespread, these mechanisms are less well understood than the self-incompatibility (SI) mechanisms plants use to reject pollen from close relatives. Previous studies have shown that some interspecific reproductive barriers (IRBs) are related to SI in the Solanaceae. For example, the pistil SI proteins S-RNase and HT protein function in a pistil-side IRB that causes rejection of pollen from self-compatible (SC) red/orange-fruited species in the tomato clade...

The incredible pollination mechanisms displayed by orchid flowers has inspired biologists over the centuries. Based on the intriguing flower structures the relation among orchid species and their pollinators has been frequently regarded as very specialized. Given that visits on flowers pollinated by oil-collecting bees are regularly rare and in Oncidiinae the flowers frequently atract exclusively species that act as effective pollinators, the comparative reproductive biology and pollinator specificity of two sympatric Gomesa (G...

Peptides have attracted considerable attention due to their biocompatibility, functional molecular recognition and unique biological and electronic properties. The strong piezoelectricity in diphenylalanine peptide expands its technological potential as a smart material. However, its random and unswitchable polarization has been the roadblock to fulfilling its potential and hence the demonstration of a piezoelectric device remains lacking. Here we show the control of polarization with an electric field applied during the peptide self-assembly process...

A 62-year-old man presented to psychiatric services with a 3-month history of a range of symptoms which included obsessional thoughts, self-neglect, lack of mental flexibility, reduced ability to plan, organise and follow instructions, reduced capacity to empathise and disinhibition. He also accidently set fire to his house. Overall these findings are compatible with a dysexecutive syndrome. This man has a significant history of polysubstance misuse and chronic hepatitis C infection. Neuroimaging revealed an acquired traumatic brain injury which could account for his dysexecutive syndrome...

In the management of chronic conditions, such as chronic obstructive pulmonary disease (COPD), there is a shift from doctor-driven care to patient-centred integrated care with active involvement of and self-management by the patient. A recently developed tool, the assessment of burden of COPD (ABC) tool, can be used in this transition to facilitate self-management support and shared decision-making. We performed a qualitative study, in which we collected and analysed the data using the methods of conventional content analyses...

Anthropogenic habitat deterioration can promote changes in plant mating systems that subsequently may affect progeny performance, thereby conditioning plant recruitment for the next generation. However, very few studies yet tested mating system parameters other than outcrossing rates; and the direct effects of the genetic diversity of the pollen received by maternal plants (i.e. correlated paternity) has often been overlooked. In this study, we investigated the relation between correlated paternity and progeny performance in two common Mediterranean shrubs, Myrtus communis and Pistacia lentiscus...

Mass production of high-quality graphene with low cost is the footstone for its widespread practical applications. We present herein a self-limited growth approach for producing graphene powders by a small-methane-flow chemical vapour deposition process on naturally abundant and industrially widely used diatomite (biosilica) substrates. Distinct from the chemically exfoliated graphene, thus-produced biomorphic graphene is highly crystallized with atomic layer-thickness controllability, structural designability and less noncarbon impurities...

Immunosensing is a widely used technique that detects the interactions between antibodies and antigens such as biochemical markers, pathogens, allergens, and tumor-associated antigens. Since target antigens are often of high molecular mass and their binding affinities are sometimes weak, the spatial arrangement of immunoglobulin Gs (IgGs) on immunosensing probes should be optimized by presenting them in as close-packed a manner as possible and reducing steric hindrance around the antigen-binding Fv regions...

Hydrogen sulfide is a critical biological messenger, but few biologically compatible methods are available for its detection in vivo. Here, we describe the design and synthesis of a novel azide-functionalized near-infrared probe, NIR-Az, for a hydrogen sulfide assay in which a self-immolative linker is incorporated between the azide moiety and phenolic dihydroxanthene fluorophore from a cyanine dye. A large "turn-on" near-infrared fluorescence signal results from the reduction of the azide group of the fluorogenic moiety to an amine, in which the self-immolative linker also enhances the accessibility of NIR-Az to hydrogen sulfide...

Separation of self-assembled three-dimensional nanostructures from excess staple strands, misfolded structures, or unattached functional elements is critical for downstream applications. Numerous purification techniques exist, with varying yields, purities, and hetero-element compatibilities. In this chapter, we focus on three such techniques-agarose gel electrophoresis, ultrafiltration, and polymeric bead pull-down-which together satisfy requirements for a range of applications.

Several neotropical orchid genera have been proposed as being sexually deceptive; however, this has been carefully tested in only a few cases. The genus Telipogon has long been assumed to be pollinated by male tachinid flies during pseudocopulatory events but no detailed confirmatory reports are available. Here, we have used an array of methods to elucidate the pollination mechanism in Telipogon peruvianus. The species presents flowers that have a mean floral longevity of 33 days and that are self-compatible, although spontaneous self-pollination does not occur...
