Strategic environmental assessment for planning mangrove ecosystems in guinea

Located between the cities of Conackry, Dubréka and Boffa the Sangarea Bay is home to mangrove-type forests undergoing various forms of pressure. In 1992, a forest management plan was put into place in order to manage the resources. It aimed at promoting socioeconomic activities while keeping the mangrove ecosystem in balance. This plan was assessed in 1999. The results showed that even though it integrated environmental and economic objectives, it failed to include the social as well as cultural contexts and it did not involve the social actors in the decision process. Hence, the plan did not meet the expected results. Still today, the economic, environmental, social and cultural criteria and effective actor involvement in the resource management have to be taken into account to maintain the fragile balance of the Bay. This study is an attempt to include these criteria while opting for a new approach for a sustainable management of the resources of the Bay. This study is a Strategic Environmental Assessment (SEA) based on the use of the multi-criteria decision tool in a context where there are several actors involved. Structuring objectives and issues at stake allows the criteria to be identified. Using the sociological data available simulated the value-system of each actor involved, and subsequently, they were all put into a model by giving various weights to the criteria. The SEA compares the existing plan (sector-wise approach) with alternative scenarios including an “integrated management plan” scenario (holistic approach), or “a complete protection of the area” scenario. The scenarios were assessed according to the quantitative and qualitative data available. The results illustrate how the multi-criteria method can be relevant as a decision tool when choosing a sustainable way to manage natural resources.

Work and the Politics of Misrecognition

In this article we examine the idea of a politics of misrecognition of working activity. We begin by introducing a distinction between the kind of recognition and misrecognition that attaches to one’s identity, and the kind of recognition and misrecognition that attaches to one’s activity. We then consider the political significance of the latter kind of recognition and misrecognition in the context of work. Drawing first on empirical research undertaken by sociologists at the Institut für Sozialforschung in Frankfurt, we argue for a differentiated concept of recognition that shows the politics of misrecognition at work to be as much a matter of conflict between modes of recognition as it is a struggle for recognition as opposed to non-recognition. The differentiated concept of recognition which allows for this empirical insight owes much to Axel Honneth’s theory. But as we argue in the section that follows, this theory is ambiguous about the normative content of the expectations of recognition that are bound up with the activity of working. This in turn makes it unclear how we should understand the normative basis of the politics of the misrecognition of what one does at work. In the final sections of the article, we suggest that the psychodynamic model of work elaborated by Christophe Dejours and others at the Conservatoire National des Arts et Métiers in Paris can shed light on this matter; that is to say, it can help to clarify the normative significance and political stakes of the misrecognition of working activity.     

A Multilevel AR(1) Model: Allowing for Inter-Individual Differences in Trait-Scores,Inertia, and Innovation Variance

In this article we consider a multilevel first-order autoregressive [AR(1)] model with random intercepts, random autoregression, and random innovation variance (i.e., the level 1 residual variance). Including random innovation variance is an important extension of the multilevel AR(1) model for two reasons. First, between-person differences in innovation variance are important from a substantive point of view, in that they capture differences in sensitivity and/or exposure to unmeasured internal and external factors that influence the process. Second, using simulation methods we show that modeling the innovation variance as fixed across individuals, when it should be modeled as a random effect, leads to biased parameter estimates. Additionally, we use simulation methods to compare maximum likelihood estimation to Bayesian estimation of the multilevel AR(1) model and investigate the trade-off between the number of individuals and the number of time points. We provide an empirical illustration by applying the extended multilevel AR(1) model to daily positive affect ratings from 89 married women over the course of 42 consecutive days.     

Order information in verbal working memory shifts the subjective midpoint in both the line bisection and the landmark tasks

A largely substantiated view in the domain of working memory is that the maintenance of serial order is achieved by generating associations of each item with an independent representation of its position, so-called position markers. Recent studies reported that the ordinal position of an item in verbal working memory interacts with spatial processing. This suggests that position markers might be spatial in nature. However, these interactions were so far observed in tasks implying a clear binary categorization of space (i.e., with left and right responses or targets). Such binary categorizations leave room for alternative interpretations, such as congruency between non-spatial categorical codes for ordinal position (e.g., begin and end) and spatial categorical codes for response (e.g., left and right). Here we discard this interpretation by providing evidence that this interaction can also be observed in a task that draws upon a continuous processing of space, the line bisection task. Specifically, bisections are modulated by ordinal position in verbal working memory, with lines bisected more towards the right after retrieving items from the end compared to the beginning of the memorized sequence. This supports the idea that position markers are intrinsically spatial in nature.     

Proprioceptive impairment and postural orientation control in Parkinson's disease

Impairment of postural control is a common consequence of Parkinson’s disease (PD). Increasing evidences demonstrate that the pathophysiology of postural disorders in PD includes deficits in proprioceptive processing and integration. However, the nature of these deficits has not been thoroughly examined. We propose to establish a link between proprioceptive impairments and postural deficits in PD using two different experimental approaches manipulating proprioceptive information. In the first one, the subjects stood on a platform that tilted slowly with oscillatory angular movements in the frontal or sagittal planes. The amplitude and frequency of these movements were kept below the semicircular canal perception threshold. Subjects were asked to maintain vertical body posture with and without vision. The orientations of body segments were analyzed. In the second one, the postural control was tested using the tendon-vibration method, which is known to generate illusory movement sensations and postural reactions. Vibrations were applied to ankle muscles. The subject’s whole-body motor responses were analyzed from center of pressure displacements.In the first experiment, the parkinsonian patients (PP) were unable to maintain the vertical trunk orientation without vision. Their performances with vision improved, without fully reaching the level of control subjects (CS). In the second experiment, the postural reactions of the PP were similar to those of the CS at the beginning of the perturbation and increased drastically at the end of the perturbation’s period as compared to those of CS and could induce fall.These results will bring new concepts to the sensorimotor postural control, to the physiopathology of posture, equilibrium and falls in PD and to the role of basal ganglia pathways in proprioception integration. Nevertheless, in order to assess precisely the role played by sensorimotor integration deficits in postural impairments in PD, further studies establishing the links between clinical features and abnormalities are now required.     

Perceived partner support and psychosexual adjustment to breast cancer

Support from a partner can play a key role in a woman's emotional adjustment to breast cancer. However, little is known about the influence of partner behaviours on a woman's sexual adjustment. This study examined the prospective relationship between baseline levels of several types of perceived partner support (instrumental, informational, emotional and negative) and psychosexual adjustment (sexual functioning and relationship satisfaction) over the course of 12 months post-surgery in a sample of 130 women with breast cancer. Results indicated that perceptions of greater emotional and informational support from the partner at baseline were associated with less sexual difficulties among breast cancer patients concurrently and 6 months post-surgery. Baseline perceptions of greater emotional and instrumental support from a partner were associated with greater relationship satisfaction at all time points. Perceptions of informational support at baseline were related to greater concurrent relationship satisfaction. Baseline perceptions of negative partner support were related to less relationship satisfaction, but only concurrently. These findings suggest that the perception of a partner's provision of emotional, instrumental and informational support may each play a role in facilitating sexual adjustment and relationship satisfaction.     

On the time course of letter perception: A masked priming ERP investigation

In an experiment measuring event-related brain potentials (ERPs), single-letter targets were preceded by briefly presented masked letter primes. Name and case consistency were manipulated across primes and targets so that the prime was either the same letter as the target (or not), and was presented in the same case as the target (or not). Separate analyses were performed for letters whose upper- and lowercase forms had similar features (or not). The results revealed an effect of prime-target visual similarity between 120 and 180 msec, an effect of case-specific letter identity between 180 and 220 msec, and an effect of case-independent letter identity between 220 and 300 msec. We argue that these ERP results reflect processing in a hierarchical system for letter recognition that involves both case-specific and case-independent representations of alphabetic stimuli.     

Masked partial priming of letter perception

In three experiments testing 178 subjects, letter targets were preceded by briefly presented, pattern-masked primes formed by deleting pixels in a larger or smaller version of the target stimulus. In Experiment 1A (alphabetic decision)and Experiment 1B (letter naming) a slight advantage was observed for global primes (alternate pixels deleted) compared with junction primes (midsegment information removed). This advantage was stronger at 50 ms prime exposures than at 30 ms exposures in the naming task. In Experiment 2 (letter naming), midsegment primes (with junction information removed) produced faster latencies than did junction primes. This result was replicated in a third experiment and was shown to be independent of target letter case and the relative size of prime and target stimuli. The same midsegment and junction primes did not facilitate performance compared to neutral primes in the alphabetic decision task. These results suggest that masked partial priming of letter naming can be usefully applied to the study of basic processes in letter perception.     

Personality features and cognitive level in patients at an early stage of Alzheimer’s disease

In this cross-sectional study, we explored the relationship between premorbid personality and its changes over 5 years, and cognitive deterioration in patients with mild Alzheimer’s disease. The cognitive level of 54 patients was compared with that of 64 control subjects using the Mini Mental State (MMSE). Family members completed the NEO-PI-R (form R) twice, once to evaluate the participants’ current personality and again to assess personality traits as they were remembered to be 5 years earlier. Furthermore, the family filled in the Informant Questionnaire on Cognitive Decline (IQCODE), the Activities of Daily Living (ADL), and the Instrumental Activities of Daily Living (IADL) scales to assess their proxies’ cognitive level and daily living functioning. Regarding the relationship between personality characteristics and cognitive status, we observed trends for premorbid personality and significant links for personality changes in the clinical group. Thus, changes in neuroticism and conscientiousness were associated with cognitive deterioration, whereas decreased openness to experience and conscientiousness over time predicted loss of independence in daily functioning in the clinical group. Our study suggests that premorbid features can be considered as latent traits linked to the neuropathology underlying the disease process, while personality changes are probably the consequences of the pathological process.
