'I-I' and 'I-me' : Transposing Buber's interpersonal attitudes to the intrapersonal plane

Hermans' polyphonic model of the self proposes that dialogical relationships can be established between multiple I-positions1 (e.g., Hermans, 2001a). There have been few attempts, however, to explicitly characterize the forms that these intrapersonal relationships may take. Drawing on Buber's (1958) distinction between the 'I-Thou' and 'I-It' attitude, it is proposed that intrapersonal relationships can take one of two forms: an 'I-I' form, in which one I-position encounters and confirms another I-position in its uniqueness and wholeness; and an 'I-Me' form, in which one I-position experiences another I-position in a detached and objectifying way. This article argues that this I-Me form of intrapersonal relating is associated with psychological distress, and that this is so for a number of reasons: Most notably, because an individual who objectifies and subjugates certain I-position cannot reconnect with more central I-positions when dominance reversal (Hermans, 2001a) takes place. On this basis, it is suggested that a key role of the therapeutic process is to help clients become more able to experience moments of I-I intrapersonal encounter, and it is argued that this requires the therapist to confirm the client both as a whole and in terms of each of his or her different voices

Towards a sustainable Dunaliella salina microalgal biorefinery for 9-cis β-carotene production

Valorisation of the efficacy of 9-cis beta-carotene in treating atherosclerosis, psoriasis, and inhibiting atherogenesis and retinitis pigmentosa is becoming increasingly urgent, but supplies of 9-cis beta-carotene are scarce and this compound is difficult to synthesise chemically, unlike the much more common all-trans form. Innovative products, processes and services in an algal biorefinery that rely on renewable biological resources instead of fossil fuel alternatives offer the potential to lower the energy costs of traditional chemical processes and reduce carbon emissions, water usage and waste. In 2013, the European Commission supported development of 4 microalgal biorefinery projects to assess the potential for innovative approaches to tackle the major challenges intrinsic to the development of the algae biorefineries. One of these was the D-Factory (KBBE.2013.3.2-02) which sought to evaluate requirements for sustainable, industrial-scale production of Dunaliella salina and extraction of its carotenoids, especially 9-cis beta-carotene in a CO2 microalgae biorefinery. Here we present findings of the D-Factory project and propose a way forward for industrial-scale production of 9-cis beta-carotene using biotechnology based on Dunaliella salina biomass. Cultivation improvements are able to deliver more than double the current levels of productivity, with increased sustainability, whilst the use of natural hyper-accumulating carotenogenic strains combined with the use of red light to boost production of the beta-carotene pathway, will increase the relative concentration of 9-cis beta-carotene in extracts of carotenoids with consequent improvements in downstream processing. These developments pave the way for acquiring data for a Medicine Licence and prepare the market for entry of novel 9-cis beta-carotene products

Clinical characteristics of rod and cone photoreceptor dystrophies in patients with mutations

METHODS. Eight patients-four diagnosed with retinitis pigmentosa (RP) and four with conerod dystrophy (CRD), carrying causal C8orf37 mutations-were clinically evaluated, including extensive medical history taking, slit-lamp biomicroscopy, ophthalmoscopy, kinetic perimetry, electroretinography (ERG), spectral-domain optical coherence tomography (SD-OCT), autofluorescence (AF) imaging, and fundus photography. RESULTS. In families A and D, respectively, one and three patients showed a classic RP phenotype with night blindness followed by concentric loss of visual field. Severe visual loss to light perception occurred early in the course of the disease. The symptoms initiated during infancy (family A) or adolescence (family D). Ophthalmoscopy revealed macular atrophy, bone spicules, attenuated vessels, and waxy pale optic discs. SD-OCT showed profound photoreceptor degeneration and AF demonstrated atrophy of the retinal pigment epithelium (RPE). ERG responses were nonrecordable in these patients. In families B and C, the patients were diagnosed with CRD. Initial symptoms were photophobia or loss of visual acuity and occurred during infancy (family B) or adolescence (family C). Ophthalmoscopy and AF revealed profound macular RPE atrophy and SD-OCT demonstrated macular photoreceptor degeneration. ERG responses were severely reduced in a cone-rod pattern or were nonrecordable. Interestingly, both patients in family B demonstrated polydactyly. CONCLUSIONS. Mutations in C8orf37 give rise to an early or adolescent-onset autosomal recessive CRD or RP phenotype with early macular atrophy. The occurrence of postaxial polydactyly in one family suggests a syndromic phenotype, which may indicate C8orf37 has a ciliary function

Rorty and Literature

This chapter addresses the relationship between Rorty's pragmatist philosophy and his view of literature and literary writing. It begins by examining the relationship between philosophy and literature, construed by Rorty in terms of the opposition between “normal,” professionalized, argument‐centered philosophical discourse and the kind of cultural criticism which emphasizes human finitude and contingency, seeking through the use of irony and literary inventiveness to transform our prevalent visions of what it means to be human. This humanist side of Rorty's argument is further developed through the discussion of the role that literature plays in intellectual self‐formation and moral edification, by educating moral sensibility and providing transformational shifts of conceptual perspective. These dynamics of literary innovation are then shown to dovetail nicely with Rorty's naturalistic, evolutionary conception of cultural development as well as his views regarding the indispensable role of the personal, the private, and the unshared in producing genuine cultural innovation

Bergsonian Intuition, Husserlian Variation, Peirceian Abduction: Toward a Relation Between Method, Sense and Nature

Husserlian variation, Bergsonian intuition and Peirceian abduction are contrasted as methodological responses to the traditional philosophical problem of deriving knowledge of universals from singulars. Each method implies a correspondingly different view of the generation of the variations from which knowledge is derived. To make sense of the latter differences, and to distinguish the different sorts of variation sought by philosophers and scientists, a distinction between extensive, intensive, and abductive-intensive variation is introduced. The link between philosophical method and the generation of variation is used to illuminate different philosophical conceptions of nature and nature’s relation to meaning and sense

Assessment of Night Vision Problems in Patients with Congenital Stationary Night Blindness

Congenital Stationary Night Blindness (CSNB) is a retinal disorder caused by a signal transmission defect between photoreceptors and bipolar cells. CSNB can be subdivided in CSNB2 (rod signal transmission reduced) and CSNB1 (rod signal transmission absent). The present study is the first in which night vision problems are assessed in CSNB patients in a systematic way, with the purpose of improving rehabilitation for these patients. We assessed the night vision problems of 13 CSNB2 patients and 9 CSNB1 patients by means of a questionnaire on low luminance situations. We furthermore investigated their dark adapted visual functions by the Goldmann Weekers dark adaptation curve, a dark adapted static visual field, and a two-dimensional version of the ‘‘Light Lab’’. In the latter test, a digital image of a living room with objects was projected on a screen. While increasing the luminance of the image, we asked the patients to report on detection and recognition of objects. The questionnaire showed that the CSNB2 patients hardly experienced any night vision problems, while all CSNB1 patients experienced some problems although they generally did not describe them as severe. The three scotopic tests showed minimally to moderately decreased dark adapted visual functions in the CSNB2 patients, with differences between patients. In contrast, the dark adapted visual functions of the CSNB1 patients were more severely affected, but showed almost no differences between patients. The results from the ‘‘2D Light Lab’’ showed that all CSNB1 patients were blind at low intensities (equal to starlight), but quickly regained vision at higher intensities (full moonlight). Just above their dark adapted thresholds both CSNB1 and CSNB2 patients had normal visual fields. From the results we conclude that night vision problems in CSNB, in contrast to what the name suggests, are not conspicuous and generally not disabling
