It's Complicated: Corporate Sustainability and the Uneasiness of Life Cycle Assessment

Abstract

Life cycle assessment (LCA) is a technique and field of expertise aimed at modeling the complete ‘cradle-to-grave’ life of goods and services, as well as their multiple impacts on environmental and human well-being. Although not new, in recent years LCA has become a central tool in corporate and government initiatives to improve overall product sustainability. These initiatives show how corporate supply chains have become increasingly important sites and objects of knowledge production. But the production process is not straightforward. LCA practitioners must navigate complicated relationships with corporations that serve as both clients and sources of vital information. The challenges of generating knowledge deemed both credible and useful are compounded by the complexity, diversity and contingency of product life cycles, as well as by ongoing debates about exactly how product sustainability should be modeled and assessed. While some of these challenges are unique to LCA, others reflect tensions common to many fields that assess corporate conduct in order to improve it.     

Five weeks of immersive reminiscence therapy improves autobiographical memory in Alzheimer’s disease

ABSTRACT

We examined the effects of a new Immersive Reminiscence Therapy (IRT) programme on cognitive function, including autobiographical memory, in a sample Alzheimer’s disease (AD) patients. A total of 43 AD patients with mild to moderate disease severity were randomly assigned to either an intervention group (n?=?22, MMMSE?=?20.77), or a control group (n?=?21, MMMSE?=?19.24). The intervention group received one weekly group-based session of IRT for five weeks in an authentic 1950s style museum environment, matching the time of the participants’ youth. IRT included semi-structured conversations about the past. The control group received standard care. We assessed performance on cognitive function and autobiographical memory at baseline and post-intervention. Five weeks of IRT enhanced subsequent autobiographical memory performance, when participants were cued by concrete objects dated to their youth. Object-cued memories reported post intervention included a significantly higher degree of episodic details and higher word counts. The intervention showed no effect on the Autobiographical Memory Interview or word-cued recall. Global cognitive function and semantic autobiographical memory performance increased across time for both groups. Our findings demonstrate that immersion into a setting, rich on concrete cues dated to the participants’ youth can improve autobiographical remembering.     

Two-year outcome of internet-based relapse prevention for partially remitted depression

The objective of the study was to investigate the long-term effects of internet-based relapse prevention for sufferers of partially remitted depression. Eighty-four individuals with partially remitted unipolar depression were randomized to either internet-based CBT (iCBT) or to a control group. After the ten week intervention period the participants were followed for 24 months and diagnostic interviews conducted to detect relapse. The intervention and monthly self-ratings of depressive symptoms were administered via an internet-based platform that ensured secure communication with all participants. Significantly fewer participants in the iCBT group had experienced a relapse compared with those in the control group two years after the internet-based intervention. The relapse rate in the iCBT group was 13.7% (CI 95% = 2.5–24.9) and in the control group it was 60.9% (CI 95% = 44.8–77). Furthermore, a significantly larger proportion of the iCBT group experienced remission two years after the intervention compared with the control group. Internet-based CBT seems promising for preventing relapse in sufferers of partially remitted depression.     

Outrage towards whom? Threats to moral group status impede striving to improve via out‐group‐directed outrage

Threats to group status can elicit different responses, ranging from those that motivate striving for improvement to those that motivate defending the threatened social identity. We examine why moral threats to group status may inhibit individuals' striving to improve. Specifically, we predicted that a threat to the group's moral status evokes a defensive emotional focus on the out‐group that impedes individuals' striving to improve. Two studies (N = 76 and N = 90) showed that moral (as opposed to nonmoral) threats elicited more outrage directed at the out‐group and, by trend, less outrage directed at the in‐group. The follow‐up study further demonstrated that moral threat impeded striving for improvement because of the relative focus of outrage on in‐group versus out‐group. Moreover, and consistent with our group‐based analysis, this pattern was most pronounced among strongly identified group members. We discuss theoretical and practical implications of framing groups' shortcomings in moral versus nonmoral terms. Copyright © 2013 John Wiley & Sons, Ltd.     

Tracking the speech signal – Time-locked MEG signals during perception of ultra-fast and moderately fast speech in blind and in sighted listeners

Blind people can learn to understand speech at ultra-high syllable rates (ca. 20 syllables/s), a capability associated with hemodynamic activation of the central-visual system. To further elucidate the neural mechanisms underlying this skill, magnetoencephalographic (MEG) measurements during listening to sentence utterances were cross-correlated with time courses derived from the speech signal (envelope, syllable onsets and pitch periodicity) to capture phase-locked MEG components (14 blind, 12 sighted subjects; speech rate = 8 or 16 syllables/s, pre-defined source regions: auditory and visual cortex, inferior frontal gyrus). Blind individuals showed stronger phase locking in auditory cortex than sighted controls, and right-hemisphere visual cortex activity correlated with syllable onsets in case of ultra-fast speech. Furthermore, inferior-frontal MEG components time-locked to pitch periodicity displayed opposite lateralization effects in sighted (towards right hemisphere) and blind subjects (left). Thus, ultra-fast speech comprehension in blind individuals appears associated with changes in early signal-related processing mechanisms both within and outside the central-auditory terrain.     

Poor motor skills: A risk marker for bully victimization

Children who are clumsy are often bullied. Nevertheless, motor skills have been overlooked in research on bullying victimization. A total of 2,730 Swedish adults (83% females) responded to retrospective questions on bullying, their talents in physical education (i.e., coordination and balls skills) and school academics. Poor talents were used as indicators of poor gross motor skills and poor academic skills. A subset of participants also provided information on educational level in adulthood, childhood obesity, belonging to an ethic minority in school and socioeconomic status relative to schoolmates. A total of 29.4% of adults reported being bullied in school, and 18.4% reported having below average gross motor skills. Of those with below average motor skills, 48.6% were bullied in school. Below average motor skills in childhood were associated with an increased risk (OR 3.01 [95% CI: 1.97–4.60]) of being bullied, even after adjusting for the influence of lower socioeconomic status, poor academic performance, being overweight, and being a bully. Higher odds for bully victimization were also associated with lower socioeconomic status (OR 2.29 [95% CI: 1.45–3.63]), being overweight (OR 1.71 [95% CI: 1.18–2.47]) and being a bully (OR 2.18 [95% CI: 1.53–3.11]). The findings indicate that poor gross motor skills constitute a robust risk‐marker for vulnerability for bully victimization. Aggr. Behav. 39:453–461, 2013. © 2013 The Authors.

Stoic Sequent Logic and Proof Theory

This paper contends that Stoic logic (i.e. Stoic analysis) deserves more attention from contemporary logicians. It sets out how, compared with contemporary propositional calculi, Stoic analysis is closest to methods of backward proof search for Gentzen-inspired substructural sequent logics, as they have been developed in logic programming and structural proof theory, and produces its proof search calculus in tree form. It shows how multiple similarities to Gentzen sequent systems combine with intriguing dissimilarities that may enrich contemporary discussion. Much of Stoic logic appears surprisingly modern: a recursively formulated syntax with some truth-functional propositional operators; analogues to cut rules, axiom schemata and Gentzen’s negation-introduction rules; an implicit variable-sharing principle and deliberate rejection of Thinning and avoidance of paradoxes of implication. These latter features mark the system out as a relevance logic, where the absence of duals for its left and right introduction rules puts it in the vicinity of McCall’s connexive logic. Methodologically, the choice of meticulously formulated meta-logical rules in lieu of axiom and inference schemata absorbs some structural rules and results in an economical, precise and elegant system that values decidability over completeness.     

Adaptive n-back training does not improve fluid intelligence at the construct level: Gains on individual tests suggest that training may enhance visuospatial processing

Short-term adaptive cognitive training based on the n-back task is reported to increase scores on individual ability tests, but the key question of whether such increases generalize to the intelligence construct is not clear. Here we evaluate fluid/abstract intelligence (Gf), crystallized/verbal intelligence (Gc), working memory capacity (WMC), and attention control (ATT) using diverse measures, with equivalent versions, for estimating any changes at the construct level after training. Beginning with a sample of 169 participants, two groups of twenty-eight women each were selected and matched for their general cognitive ability scores and demographic variables. Under strict supervision in the laboratory, the training group completed an intensive adaptive training program based on the n-back task (visual, auditory, and dual versions) across twenty-four sessions distributed over twelve weeks. Results showed that this group had the expected systematic improvements in n-back performance over time; this performance systematically correlated across sessions with Gf, Gc, and WMC, but not with ATT. However, the main finding showed no significant changes in the assessed psychological constructs for the training group as compared with the control group. Nevertheless, post-hoc analyses suggested that specific tests and tasks tapping visuospatial processing might be sensitive to training.     

Perceived Church-Based Needs and Assets for HIV/AIDS Prevention in an Urban Nigerian Community

Health intervention programs have the potential to use church-based assets to address a wide range of health issues. This study examined the assets Nigerian church members believed their churches needed, including the assets they thought they had to engage in HIV/AIDS prevention activities. Eight hundred and thirty members from 83 churches completed a questionnaire designed from forum focus group data. Respondents were males and females aged 18 years old and above, with primary, secondary, university, or vocational education, and were more likely to be married than single (never married), separated, divorced, widowed or remarried. The data revealed that church members needed access to health promotion assets, including the expertise of members who are health professionals to engage in HIV/AIDS prevention activities. We recommend an intensive HIV/AIDS prevention reorientation-training workshop for church leaders to ensure a sustainable plan to address HIV/AIDS prevention needs.
