Retail governance and agrifood sustainability: insights and research needs

"Food security, food safety, healthy consumption habits, and environmental sustainability are essential to the well-being of societies worldwide. Yet, progress in fostering sustainability in the global agrifood system has been slow at best and significant challenges remain. First, food insecurity remains a problem for millions of people, while its range and consequences have been aggravated by the recent food crisis (FAO 2008b). Second, repeated food scandals and health scares constitute additional challenges for food governance (World Bank 2005). Food is the number one cause of premature death in the western world due to the increasing consumption of fattier, saltier, and sweeter foods and drinks (Popkin 2002). Even in many Asian countries obesogenic diets are becoming more prevalent (Florentino 2002; IOTF 2005). Third, threats to the provision of adequate amounts of nutritious food are expected to multiply as a result of climate change (European Commission 2008a). At the same time, the food sector itself is a major contributor to direct and indirect greenhouse gas emissions (FAO 2008a). Fourth, alternative food products – while promising environmental and health benefits in relation to their conventional equivalents – are also associated with costs. In India, thousands of farmers have reportedly committed suicide, partly as a result of debt due to unfair biotech deals (Nagaraj 2008).(...)" [authors remark

Does politics impact carbon emissions?

"Do political variables influence long-term environmental transitions? The discussion on the determinants of the environmental performance of countries has been dominated by a focus on the Environmental Kuznets curve. This concept concentrated primarily on the role of economic factors, in particular per capita income levels. By contrast, we outline both conceptually and empirically how political factors can affect long-term carbon trajectories. Our findings from an error-correction model suggest that political factors are an important explanatory variable for carbon emissions in over 100 countries during the period 1970-2004. The results show that political capacity reduces carbon emission in OECD countries whereas political constraints, democracy and the Kyoto Protocol reduce long-term carbon emission in the group of all countries as well as in non-OECD countries."

Enhancing scientific communication skills: a real-world simulation in a tertiary-level life science class using e-learning technology in biomedical literature perception, reflective review writing on a clinical issue, and self and peer assessments

This educational study aimed to explore the feasibility and acceptance of a literacy exercise adopted from the realworld of scientific publishing in a cell and tissue biology course. For that purpose, a tertiary-level multimodality science course, which integrated a blended learning faculty and student lectures, journal club, and wet laboratory sessions including a research project as well as examinations, was complemented by essaywriting of a review and peerreviewing of five manuscripts. All tasks contributed to the final course mark. Special emphasis was laid on the usability of different E-Learning applications for scientific writing and teacher- and peerassessment procedures. Further, potential influences of student characteristics on their peerand self-assessments as well as their acceptance of the feedback from their peers were evaluated. Seventy-five undergraduate students from different Bachelor programs were included in the study. Plagiarism check and double-blind assessments of the essays were performed using “Turnitin.com.” Students self- assessed their paper and received feedback from five peers and the teacher. Peer assessment was more severe than the teacher- or self-assessment, and the peer mark correlated best with the final course mark. Students with better marks assessed more generously, and there had moderate tendencies for influences of gender and background on peer feedback behavior. The students perceived the writing and assessment exercises, especially being peer-assessed, as demanding, but rewarding and a great learning experience. The additional tasks were feasible using E-Learning technology, which should foster future biomedical courses to train writing skills and the ability to cope with different roles in the scientific community

Beyond Simple Substitution Patterns âEuro" Symmetrically Tetrasubstituted [2.2]Paracyclophanes as 3D Functional Materials

[2.2]Paracyclophane is the prototypical layered hydrocarbon and has been essential for investigations of through-space electronic interactions. Over the last years more examples of tetrasubstituted derivatives have been reported. This minireview discusses the synthetic approaches towards various substitution patterns and provides a survey over different approaches used to achieve and derivatize symmetric tetrasubstitution. The first two sections of this work present homo-tetrasubstituted derivatives, while the third section gives insight into symmetrically hetero-tetrasubstituted analogues. These approaches are briefly discussed, the resulting structures are presented in detail, and their specific properties resulting from the incorporation of [2.2]paracyclophane are elucidated

At the edge of intonation: the interplay of utterance-final F0 movements and voiceless fricative sounds

The paper is concerned with the 'edge of intonation' in a twofold sense. It focuses on utterance-final F0 movements and crosses the traditional segment-prosody divide by investigating the interplay of F0 and voiceless fricatives in speech production. An experiment was performed for German with four types of voiceless fricatives: /f/, /s/, /ʃ/ and /x/. They were elicited with scripted dialogues in the contexts of terminal falling statement and high rising question intonations. Acoustic analyses show that fricatives concluding the high rising question intonations had higher mean centres of gravity (CoGs), larger CoG ranges and higher noise energy levels than fricatives concluding the terminal falling statement intonations. The different spectral-energy patterns are suitable to induce percepts of a high 'aperiodic pitch' at the end of the questions and of a low 'aperiodic pitch' at the end of the statements. The results are discussed with regard to the possible existence of 'segmental intonation' and its implication for F0 truncation and the segment-prosody dichotomy, in which segments are the alleged troublemakers for the production and perception of intonation

The antecedents of cross-functional coordination and their implications for marketing adaptiveness

As the gap between accelerating rate of change and organizational capability in responding to it widens, managers face increasing challenges to coordinate and align diverse intra-firm functions. Although coordination across functions in an organization is necessary for integrating complex resources such as responding to uncertainty in business environments, little is known about the internal conditions of a firm in which cross-functional coordination influences marketing adaptiveness. Marketing adaptiveness recognizes the potential conflicting goals of intra-firm functions, and the need to identify disparate but interdependent organizational resources to fit the external environment. In order to account for the potential interactions of multiple conditions in cross-functional coordination, we use fuzzy-set qualitative comparative analysis to analyze survey data of 274 managers in Egyptian firms operating in uncertain environments based on the motivation-ability-opportunity framework and configuration theory. The findings show that the causal pathways leading to cross-functional coordination and marketing adaptiveness can be enhanced by resource dependency, cross-functional teams, multifunctional training, and management support. In particular, management support is a crucial condition for coordination in support of cross-functional teams and multifunctional training. While resource dependency is an important internal factor for coordination, a high resource dependency can result in a negative effect on marketing adaptiveness

The Vulnverability Cube: A Multi-Dimensional Framework for Assessing Relative Vulnerability

The diversity and abundance of information available for vulnerability assessments can present a challenge to decision-makers. Here we propose a framework to aggregate and present socioeconomic and environmental data in a visual vulnerability assessment that will help prioritize management options for communities vulnerable to environmental change. Socioeconomic and environmental data are aggregated into distinct categorical indices across three dimensions and arranged in a cube, so that individual communities can be plotted in a three-dimensional space to assess the type and relative magnitude of the communities’ vulnerabilities based on their position in the cube. We present an example assessment using a subset of the USEPA National Estuary Program (NEP) estuaries: coastal communities vulnerable to the effects of environmental change on ecosystem health and water quality. Using three categorical indices created from a pool of publicly available data (socioeconomic index, land use index, estuary condition index), the estuaries were ranked based on their normalized averaged scores and then plotted along the three axes to form a vulnerability cube. The position of each community within the three-dimensional space communicates both the types of vulnerability endemic to each estuary and allows for the clustering of estuaries with like-vulnerabilities to be classified into typologies. The typologies highlight specific vulnerability descriptions that may be helpful in creating specific management strategies. The data used to create the categorical indices are flexible depending on the goals of the decision makers, as different data should be chosen based on availability or importance to the system. Therefore, the analysis can be tailored to specific types of communities, allowing a data rich process to inform decision-making

Pathogens and host immunity in the ancient human oral cavity.

Calcified dental plaque (dental calculus) preserves for millennia and entraps biomolecules from all domains of life and viruses. We report the first, to our knowledge, high-resolution taxonomic and protein functional characterization of the ancient oral microbiome and demonstrate that the oral cavity has long served as a reservoir for bacteria implicated in both local and systemic disease. We characterize (i) the ancient oral microbiome in a diseased state, (ii) 40 opportunistic pathogens, (iii) ancient human-associated putative antibiotic resistance genes, (iv) a genome reconstruction of the periodontal pathogen Tannerella forsythia, (v) 239 bacterial and 43 human proteins, allowing confirmation of a long-term association between host immune factors, 'red complex' pathogens and periodontal disease, and (vi) DNA sequences matching dietary sources. Directly datable and nearly ubiquitous, dental calculus permits the simultaneous investigation of pathogen activity, host immunity and diet, thereby extending direct investigation of common diseases into the human evolutionary past
