Stormwater management has transformed throughout the decades with the purpose of maintaining the pre-development hydrological cycle to protect humans and the environment. Despite the progress, Ontario’s water bodies have continued to degrade. This research discusses and recommends three essential modifications to stormwater management to increase environmental and human protection. These include: 1) management based on the four seasons, 2) management based on regional conditions such as local climate and receiving water body characteristics, and 3) updating current stormwater management objectives to provide detailed direction. The Etobicoke Exfiltration System is used as a case study to demonstrate some aspects of the proposed stormwater management modifications and to show the benefits of addressing the five stormwater characteristics (volume, peak flow, quality, duration, frequency) throughout the year. Modelling its performance under 2 to 100 year Chicago storms and use of previous EES studies show the wide range of objectives it can achieve. Future stormwater designs should look to the EES as insight into how stormwater can be properly managed.

Evaporites characterize the Lopingian of Europe but present obstacles for biostratigraphic analysis. Here we present a case study for processing the Lopingian Zechstein Group evaporites of central-western Europe for the recovery of palynomorph assemblages. We demonstrate that full recovery is easily achieved with two main modes of palynomorph preservation observed; palynomorphs are either exceptionally well-preserved and orange-brown in colour, or poorly-preserved, brown-black, opaque and fragmented. The latter are reminiscent of palynomorphs of high thermal maturity. However, we propose that the intact nature of preservation is a result of the rapid growth of near-surface halite crystals, with their darkening a consequence of locally-enhanced heat flux due to the relatively high thermal conductivity of salt. This case study has enabled novel insight into an otherwise undescribed environment, and demonstrates the utility and possibility of extracting palynomorphs from a variety of rock salt types. This method should be applicable to a wide range of ancient evaporite and could also be applied to other Permian evaporite systems, which are used as analogues for extra-terrestrial environments.

Abstract Storm-water management is a common concern in rural catchments where development-related growth causes increases of storm-water flows. Greater magnitude and frequency of storm-water create greater challenges for mitigating storm-water damage and improving water quality. The concept of Blue-Green Infrastructure (BGI) as a solution incorporates a wide range of applicable components with the aim of minimizing the effect of catchment development on flow regimes without changing the watershed morphology. BGI components manage storm-water by decreasing impermeable cover and expanding natural and semi-natural systems to store water or recharge and filter storm-water into the ground. In this paper, guidelines for designing a pond as a component of BGI are provided and, configuration and size of the pond are determined. Moreover, the impacts of the designed pond on storm-water peak flow and quality are assessed for the Tarwin catchment, State of Victoria, Australia. The results indicate that the introduction of the pond would have reduced outfall inflow by 94 % and would have achieved the reduction of 88.3, 75.5 and 50.7 % for total suspended solids, total phosphorus, and total nitrogen respectively, during the extreme weather event in June 2012.

Purpose Being innovative and bringing new products to the market fast is important for firms to stay competitive. Customers are important for providing input to product developments in industrial markets. The purpose of this paper is to increase understanding of how firms use Voice of the Customer (VoC) in product development and how VoC can complement other customer involvement methods. Design/methodology/approach The paper is based on a qualitative case study of a global leading and innovative firm, a maker of tools for the automotive industry. The study provides detailed insight into the implementation of VoC for product development. Findings The process of customer involvement in product development through VoC is explored. The study shows that by using the VoC method, firms can gather knowledge for input to product development projects while developing relationships with a larger number of customers. The findings point out that VoC can be modified to focus on customer needs related to product development as well as marketing efforts requiring cross-functional collaboration. The VoC method is suitable for combining with other customer involvement methods such as project involvement and pilot testing. Through VoC, firms have the chance to benchmark across industries and regions. Research limitations/implications The paper provides insights into the VoC process of customer involvement aimed at product development. The case study provides an illustration of how an industrial firm uses VoC in product development. The paper points out the importance of managing external (customer) involvement in product development and internal (cross-functional) collaborations. Practical implications A set of questions that firms can ask themselves before embarking on customer involvement has been developed. The paper shows that customers can be involved at a number of points in time, have a wide range of roles and contribute different knowledge. VoC is suitable for combining with other customer involvement methods. Originality/value The contribution of the paper consists of a case study illustrating how customer involvement in product development can be achieved through VoC. A number of customer involvement methods for product development are discussed for combining with VoC, showing how different methods are complementary in product development.

Long noncoding RNAs (lncRNAs) have a wide range of functions in health and disease, but many remain uncharacterized because of their complex expression patterns and structures. The genetic loci encoding lncRNAs can be subject to accelerated evolutionary changes within the human lineage. HAR1 is a region that has a significantly altered sequence compared to other primates and is a component of two overlapping lncRNA loci, HAR1A and HAR1B. Although the functions of these lncRNAs are unknown, they have been associated with neurological disorders and cancer. Here, we explore the current state of understanding of evolution in human lncRNA genes, using the HAR1 locus as the case study.

Insight Into

Phylogenetic comparative methods are increasingly used to give new insight into variation, causes and consequences of trait variation among species. The foundation of these methods is a suite of models that attempt to capture evolutionary patterns by extending the Brownian constant variance model. However, the parameters of these models have been hypothesised to be biased and only asymptotically behave in a statistically predictable way as datasets become large. This does not seem to be widely appreciated. We show that a commonly used model in evolutionary biology (the Ornstein-Uhlenbeck model) is biased over a wide range of conditions. Many studies fitting this model use datasets that are small and prone to substantial biases. Our results suggest that simulating fitted models and comparing with empirical results is critical when fitting OU and other extensions of the Brownian model.

AbstractIn a small group of deaf sign language users from different countries and with no shared language, the signers’ initial conversational interactions are investigated as they meet in pairs for the very first time. This case study allows for a unique insight into the initial stages of pidginisation and the conceptual processes involved. The participants use a wide range of linguistic and communicative resources, and it can be argued that they construct shared multilingual-multimodal cognitive spaces for the purpose of these conversations. This research explores the nature of these shared multilingual-multimodal spaces, how they are shaped by the signers in interaction, and how they can be understood in terms of conceptual blending. The research also focuses on the meta-linguistic skills that signers use in these multilingual-multimodal interactions to “make meaning”.

Summary One of the most challenging experiences psychiatrists will face in their careers may well be the death of a patient by suicide. This is likely to happen at least once during a psychiatrist's career, and often more. It can be an intensely complex and painful event with a wide range of emotional responses. Reflecting on the death and accessing good support helps clinicians process the emotional impact. It can also increase their resilience in the longer term by giving them a greater understanding of both their own and their patients’ limitations, and in this way strengthen their capacity for compassion as clinicians. Using an illustrative case study, this article provides an insight into the experience of losing a patient to suicide and signposts to sources of support.

Insight Into

The genre of annotated verse represents an under-explored form of transporting romanticism. In annotated, locodescriptive poems like those in Anna Seward's Llangollen Vale, readers are invited to read not only the spatiality of the landscapes depicted in the verse but also the landscape of the page itself. Seward's poems, with their focus on understanding geographical, political, and historical spaces both real and imaginary, provide geocritical insight into poetic productions of the early Romantic era. Likewise, geocriticism offers a fresh and useful – even necessary – analytic approach to such poems. I adopt Anna Seward as a case study in annotated verse and argue that attending to the materiality and paratextuality of her work allows us to access the complexities of her poetry and prose as well as her position within the wider framework of transporting Romanticism.
