Mechanisms of Ageing and Development | Year: 2017

The paper shows the importance of serendipity and exaptation in selected key moments of ageing research and argue that rationalistic dominant models in scientific research have masked the importance of reverse models of discovery based on serendipity and exaptation. I ask why this is the case and analyze three contributing factors: unprestatability of the functions of technologies, multidimensionality and astronomical complexity of the space over which biological reactions occurs and role of scientific paradigms in channeling research toward incrementalism. Empirical evidence of the limits of the rationalistic models are presented next. I close the paper by discussing the implications for aging research. © 2017 Elsevier B.V.

There are many studies on container port efficiency and that seek to understand what factors, such as technical and scale efficiency, private versus public terminal management or macro-economic factors, play on the efficiency score of a given port. There are fewer studies that focus on the role played by the inter-port competitive environment. This role remains difficult to assess. In fact, on the one hand, a port subject to high inter-port competition may record higher efficiency scores due to the pressure from the competitive environment. On the other hand, a port subject to high competition may be forced to over-invest and could therefore records a lower efficiency score. This article investigates this issue and examines how the degree of competition measured at different levels (local, regional and global level) impacts the efficiency score of a given container port. To do so, we implement a truncated regression with a parametric bootstrapping model. The model applied to information gathered for 200 container ports in 2007 and 2010 leads to the following conclusions: port efficiency decreases with competition intensity when measured in a range of 400-800. km (regional level); and the effect from competition is not significant when competition is measured at a local (less than 300. km) or at a global (more than 800. km) level. Estimates also show a tendency for ports who invested from 2007 to 2010 to experience a general decrease in efficiency scores, an element which could be explained by the time lag between the investment and the subsequent potential increase in container throughput. © 2015 Elsevier Ltd.

A frequent criticism of eco-efficiency strategies is that an increase in efficiency can be offset by the rebound effect. Sufficiency is discussed as a new strategy involving self-imposed restriction of consumption but can also be subject to the rebound effect. We show that the range of possible secondary effects of efficiency and sufficiency strategies goes beyond the rebound effect. The rebound effect can indeed also be linked to eco-sufficiency strategies but there are further secondary effects of both eco-efficiency and eco-sufficiency strategies, such as double dividend effects. We develop an 'Eco-efficiency- sufficiency matrix' to logically order eco-efficiency and sufficiency measures to attain lower resource consumption and emissions. © 2014 Elsevier Ltd.

Knowledge-intensive business services (KIBS) use and user innovation: high-order services, geographic hierarchies and internet use in Quebec's manufacturing sector, Regional Studies. Geographic proximity between users and suppliers of knowledge-intensive business services (KIBS) provides no advantage in terms of innovation performance. This paper first establishes that it is those KIBS most closely associated with innovation that exhibit the highest mean distance to their users. It then shows that there is no connection between distance to KIBS suppliers and propensity to innovate. These results point to a Christallerian logic whereby innovators seek out KIBS (irrespective of distance), but whereby mean distances tend to be greater between users and innovation-related KIBS suppliers (located in central places), reflecting the different geographies of manufacturing users and service suppliers. © 2014 Regional Studies Association.

We studied an interactive (functional and intentional interactivity) and immersive (technical and psychological immersion) device with a personal 3D viewer (360° vision and environmentally ego-centered) and its effects on the explicit long-term memories of the subjects (4 groups of 30 students for a total of 120 subjects) (2007 and 2012).We have tested memory, communication and feeling of presence in our virtual environment with a canonic test of presence (Witmer and Singer, 1998). This article is a reflection on these 3D devices and their impact on the long term memory of the students, and on their presence sensation. © 2014 Springer International Publishing.

We analyze the suitability of cross-sector partnerships as an effective mechanism for private environmental governance. By focusing on the interaction between firms within cross-sector partnerships, we analyze how competition between firms affects partnership effectiveness. Marrying insights from the private governance literature with institutional theory and the resource-based view, we identify under which conditions firm-level competition for legitimacy and capabilities, respectively, undermines or enhances effectiveness of cross-sector partnerships to address environmental issues. In doing so, our argument develops the various factors that moderate the relationship between competition and effectiveness for different types of partnerships. We contend that the effectiveness of cross-sector partnerships for governing global environmental issues depends considerably on whether competitive forces at the firm level are aligned with the collective benefits of partnerships. We discuss the consequences for designing effective cross-sector partnerships as well as the implications of a firm perspective on private governance. © 2014 SAGE Publications.

Consumption Markets and Culture | Year: 2015

This article explores how sustainable-oriented changes in food consumption are intertwined in dispersed movements of material and immaterial entities in both markets and society. The adoption of the notion of agencement offers the potential to consider the complexity of consumption from a market perspective: turning away from the simple, traditional production–consumers opposition approach and highlighting the performative character of the links between elements at play. Consequently, consumption becomes a market-wide issue rather than one relating to neither consumers alone nor just supplier–consumer exchange. Our analysis, with the focus on the attempts by various players in the market to configure and reconfigure a sustainable form of (non-)palm oil consumption, brings us to reflect on the development of arrangements over time and movement in consumption. This leads in conclusion, in order to appropriately capture the above-mentioned phenomena, to the proposal of the notion of multiplex consumption. © 2014, © 2014 Taylor & Francis.

Offshoring occurs when a production unit is relocated to another country but there is also the possibility to outsource the process to a foreign supplier, thus appears the necessity to choose between a strictly speaking offshoring strategy and an offshore outsourcing one. The main question of our research is: "how to take an international relocation decision?" We will use a SWOT-AHP hybrid model to analyze the decision and organize it rigorously. Our model allows us to test the potential choices that a decision to offshore encompasses: from producing internally but abroad, to offshore outsourcing, or simply to abandon the idea and continue production locally. SWOT-AHP analysis allows to get a structured thinking and take into account the internal and external environment of the firm in line with a make-or-buy strategy.

Some scholars consider that today's market conditions are in favor of the Northern Sea Route (NSR) rather than the Suez Canal Route (SCR). However, the number of bulk carriers using the NSR remains extremely limited, despite higher fuel prices since 2009 and subsequent significant fuel savings. In 2013, there were 53 transits via the Arctic, out of which 27 by oil tankers and 6 by bulk carriers. In this article we show that this result might be attributable to a factor, which is not considered in most studies: the spot freight rate to fuel ratio which governs ship owners' decisions regarding the sailing speed. Due to a low ratio since 2011, the speed of vessels on the SCR is at its lowest level, and potential NSR fuel savings are too limited to provide a viable alternative. We further argue that, contrary to most studies, internalizing NSR environmental benefits marginally improves the attractiveness of the NSR. © 2015 Elsevier Ltd.

Temporal demand aggregation has been shown in the academic literature to be an intuitively appealing and effective approach to deal with demand uncertainty for fast moving and intermittent moving items. There are two different types of temporal aggregation: non-overlapping and overlapping. In the former case, the time series are divided into consecutive non-overlapping buckets of time where the length of the time bucket equals the aggregation level. The latter case is similar to a moving window technique where the window's size is equal to the aggregation level. At each period, the window is moved one step ahead, so the oldest observation is dropped and the newest is included. In a stock-control context, the aggregation level is generally set to equal the lead-time. In this paper, we analytically compare the statistical performance of the two approaches. By means of numerical and empirical investigations, we show that unless the demand history is short, there is a clear advantage of using overlapping blocks instead of the non-overlapping approach. It is also found that the margin of this advantage becomes greater for longer lead-times. © 2016.
