Good and bad increases in ecological awareness: environmental differentiation revisited

We analyze a vertically differentiated market, assuming that conventional and green firms' products have different impacts on the environment. Heterogeneous consumers choose to be supplied by a conventional or a green firm, depending on their extra willingness to pay for a green product and the relative prices of the products in the market. We show that environmental awareness campaigns may have a negative impact on total welfare. This possibility is shown to exist without consumer misperceptions about the quality of green products and ruling out changes in the coverage and the structure of the market. Surprisingly, both conventional and green firms may benefit from heterogeneity-enhancing awareness campaigns, while social welfare is more likely to be enhanced by heterogeneity-reducing ones.

Avoiding a bad apple: insect pollination enhances fruit quality and economic value

Insect pollination is important for food production globally and apples are one of the major fruit crops which are reliant on this ecosystem service. It is fundamentally important that the full range of benefits of insect pollination to crop production are understood, if the costs of interventions aiming to enhance pollination are to be compared against the costs of the interventions themselves. Most previous studies have simply assessed the benefits of pollination to crop yield and ignored quality benefits and how these translate through to economic values. In the present study we examine the influence of insect pollination services on farmgate output of two important UK apple varieties; Gala and Cox. Using field experiments, we quantify the influence of insect pollination on yield and importantly quality and whether either may be limited by sub-optimal insect pollination. Using an expanded bioeconomic model we value insect pollination to UK apple production and establish the potential for improvement through pollination service management. We show that insects are essential in the production of both varieties of apple in the UK and contribute a total of £36.7 million per annum, over £6 million more than the value calculated using more conventional dependence ratio methods. Insect pollination not only affects the quantity of production but can also have marked impacts on the quality of apples, influencing size, shape and effecting their classification for market. These effects are variety specific however. Due to the influence of pollination on both yield and quality in Gala, there is potential for insect pollination services to improve UK output by up to £5.7 million per annum. Our research shows that continued pollinator decline could have serious financial implications for the apple industry but there is considerable scope through management of wild pollinators or using managed pollinator augmentation, to improve the quality of production. Furthermore, we show that it is critically important to consider all production parameters including quality, varietal differences and management costs when valuing the pollination service of any crop so investment in pollinator management can be proportional to its contribution.

The effects of corporate social performance on the cost of corporate debt and credit ratings

This study investigates the differential impact that various dimensions of corporate social performance have on the pricing of corporate debt as well as the assessment of the credit quality of specific bond issues. The empirical analysis, based on an extensive longitudinal data set, suggests that overall, good performance is rewarded and corporate social transgressions are penalized through lower and higher corporate bond yield spreads, respectively. Similar conclusions can be drawn when focusing on either the bond rating assigned to a specific debt issue or the probability of it being considered to be an asset of speculative grade.

Writing in French in secondary schools in England and Germany: are the British really 'bad language learners’?

It is widely assumed that the British are poorer modern foreign language (MFL) learners than their fellow Europeans. Motivation has often been seen as the main cause of this perceived disparity in language learning success. However, there have also been suggestions that curricular and pedagogical factors may play a part. This article reports a research project investigating how German and English 14- to 16-year-old learners of French as a first foreign language compare to one another in their vocabulary knowledge and in the lexical diversity, accuracy and syntactic complexity of their writing. Students from comparable schools in Germany and England were set two writing tasks which were marked by three French native speakers using standardised criteria aligned to the Common European Framework of Reference (CEF). Receptive vocabulary size and lexical diversity were established by the X_lex test and a verb types measure respectively. Syntactic complexity and formal accuracy were respectively assessed using the mean length of T-units (MLTU) and words/error metrics. Students' and teachers' questionnaires and semi-structured interviews were used to provide information and participants' views on classroom practices, while typical textbooks and feedback samples were analysed to establish differences in materials-related input and feedback in the two countries. The German groups were found to be superior in vocabulary size, and in the accuracy, lexical diversity and overall quality – but not the syntactic complexity – of their writing. The differences in performance outcomes are analysed and discussed with regard to variables related to the educational contexts (e.g. curriculum design and methodology).

Are Good or Bad Borrowers Discouraged From Applying for Loans?

This paper takes the concept of a discouraged borrower originally formulated by Kon and Storey [Kon, Y., Storey, D.J., 2003. A theory of discouraged borrowers. Small Business Economics 21, 37–49] and examines whether discouragement is an efficient self-rationing mechanism. Using US data it finds riskier borrowers have higher probabilities of discouragement, which increase with longer financial relationships, suggesting discouragement is an efficient self-rationing mechanism. It also finds low risk borrowers are less likely to be discouraged in concentrated markets than in competitive markets and that, in concentrated markets, high risk borrowers are more likely to be discouraged the longer their financial relationships. We conclude discouragement is more efficient in concentrated, than in competitive, markets.

The Role of Collateral in Entrepreneurial Finance

Previous research has suggested collateral has the role of sorting entrepreneurs either by observed risk or by private information. In order to test these roles, this paper develops a model which incorporates a signalling process (sorting by observed risk) into the design of an incentivecompatible menu of loan contracts which works as a self-selection mechanism (sorting by private information). It then tests this Sorting by Signalling and Self-Selection Model, using the 1998 US Survey of Small Business Finances. It reports for the first time that: high type entrepreneurs are more likely to pledge collateral and pay a lower interest rate; and entrepreneurs who transfer good signals enjoy better contracts than those transferring bad signals. These findings suggest that the Sorting by Signalling and Self-Selection Model sheds more light on entrepreneurial debt finance than either the sorting-by-observed-risk or the sorting-by-private information paradigms on their own.

Do good deeds make bad people?

According to the so-called ‘self-licensing effect’, committing to a virtuous act in a preceding choice may lead to behave less virtuously in the succeeding decision. Consequently, well-intentioned policies can lead to overall counter-productive effects by licensing people to behave badly in related behaviors. On the other side, motivational crowding theory argues that constraining people to adopt a desirable behavior can backfire. We use of a classroom experiment to test whether a regulatory framework to incentivize individuals to adopt pro-environmental behavior generate similar spillovers in terms of licensing effect than a non-regulatory framework. We show that the way the good deed is caused doesn’t seem to influence the licensing effect. Nevertheless, we found that business- and environmental-orientated majors react adversely to the regulatory framework. We show that environmental-orientated students exhibit higher intrinsically motivations than business-orientated ones. Accordingly, we suggest that the licensing effect is more likely to arise when the preceding ‘virtuous’ act is freely chosen (respectively regulatory caused) for non-intrinsically (respectively intrinsically) motivated individuals.

Phenylephrine promotes phosphorylation of Bad in cardiac myocytes through the extracellular signal-regulated kinases 1/2 and protein kinase A.

Studies in non-cardiomyocytic cells have shown that phosphorylation of the Bcl-2 family protein Bad on Ser-112, Ser-136 and Ser-155 decreases its pro-apoptotic activity. Both phenylephrine (100 microM) and the cell membrane-permeating cAMP analog, 8-(4-chlorophenylthio)-cAMP (100 microM), protected against 2-deoxy-D-glucose-induced apoptosis in neonatal rat cardiac myocytes as assessed by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL). In cardiac myocytes, phenylephrine primarily stimulates the alpha-adrenoceptor, but, at high concentrations (100 microM), it also increases the activity of the cAMP-dependent protein kinase, protein kinase A (PKA) through the beta-adrenoceptor. Phenylephrine (100 microM) promoted rapid phosphorylation of Bad(Ser-112) and Bad(Ser-155), though we were unable to detect phosphorylation of Bad(Ser-136). Phosphorylation of Bad(Ser-112) was antagonized by either prazosin or propranolol, indicating that this phosphorylation required stimulation of both alpha(1)- and beta-adrenoceptors. Phosphorylation of Bad(Ser-155) was antagonized only by propranolol and was thus mediated through the beta-adrenoceptor. Inhibitor studies and partial purification of candidate kinases by fast protein liquid chromatography showed that the p90 ribosomal S6 kinases, p90RSK2/3 [which are activated by the extracellular signal-regulated kinases 1 and 2 (ERK1/2)] directly phosphorylated Bad(Ser-112), whereas the PKA catalytic subunit directly phosphorylated Bad(Ser-155). However, efficient phosphorylation of Bad(Ser-112) also required PKA activity. These data suggest that, although p90RSK2/3 phosphorylate Bad(Ser-112) directly, phosphorylation of this site is enhanced by phosphorylation of Bad(Ser-155). These phosphorylations potentially diminish the pro-apoptotic activity of Bad and contribute to the cytoprotective effects of phenylephrine and 8-(4-chlorophenylthio)-cAMP.

The effects of corporate and country sustainability characteristics on the cost of debt: an international investigation

We investigate the relationship between corporate and country sustainability on the cost of bank loans. We look into 470 loan agreements signed between 2005 and 2012 with borrowers based in 28 different countries across the world and operating in all major industries. Our principal findings reveal that country sustainability, relating to both social and environmental frameworks, has a statistically and economically impactful effect on direct financing of economic activity. An increase of one unit in a country's sustainability score is associated with an average decrease in the cost of debt by 64 basis points. Our international analysis shows that the environmental dimension of a country's institutional framework is approximately twice as impactful as the social dimension, when it comes to determining the cost of corporate loans. On the other hand, we find no conclusive evidence that firm-level sustainability influences the interest rates charged to borrowing firms by banks. Our main findings survive a battery of robustness tests and additional analyses concerning subsamples, alternative sustainability metrics and the effects of financial crisis.

Bad reduction of genus three curves with complex multiplication

Let C be a smooth, absolutely irreducible genus 3 curve over a number field M. Suppose that the Jacobian of C has complex multiplication by a sextic CM-field K. Suppose further that K contains no imaginary quadratic subfield. We give a bound on the primes p of M such that the stable reduction of C at p contains three irreducible components of genus 1.

The Secret Aria on Shame : An Analysis of Narrative Structure and Theme in Coetzee's "Diary of a Bad Year"

Coetzee’s last novel Diary of a Bad Year (2007) has an intriguing triple-voiced narrative structure and deals with the grey area of shame. The narrative is divided between a writer, his written contribution to a book called “Strong Opinions”, and his secretary’s thoughts about both the opinions in the manuscript and her employer’s circumstances. This essay explores the relation between form and theme in Diary of a Bad Year; to see in what way these two fundamental elements of the novel intervene and support each other. By doing so the narrative structure is read through Freud’s structural model of personality, whereby each narrator’s voice is related to the notions of the super-ego, the ego and the id. In other words, this essay argues that the specific threefold narrative structure in Diary of a Bad Year, by reflecting the interrelated parts of human identity, helps in creating and developing the theme of shame, which only exists connected to the human psyche. This connection in turn gives special meaning to the entire narratology of the novel.

Ett bad när som helst : Dimensioneringsråd för varmvatten

Rapporten Ett bad när som helst - Dimensioneringsråd för varmvatten är framtagen av Johan Vestlund inom delprojekt Sol- och biovärme.Syftet med studien är att utreda vilka kriterier som gäller i en ackumulatortank med dubbla varmvattenslingor för att i alla situationer kunna leverera tillräckligt med varmvatten för en badkarsuppfyllning. Enkla underlag för att beräkna erforderlig slinglängd har tidigare saknats och tidsödande provning har behövt genomföras för att optimera varmvattenkapaciteten i ackumulatortankar. I denna rapport presenteras ett nomogram (figur 4, sida 13) som visar sambandet mellan be-redskapsvolym, temperaturnivå och slinglängd för att uppfylla Boverkets byggregler för ett småhus.Att tillräcklig varmvattenkomfort erhålls är viktigt, också för att kunden ska bli nöjd med ett solvärmesystem. Att detta kan ske vid rimliga tanktemperaturer på 60-65 °C är viktigt för att solvärmetillskottet ska bli högt. Ökad varmvattenkomfort ökar energibehovet och minskar solvärmebidraget varför det är viktigt att dimensionera korrekt. Utgångspunkten för att bygga ett effektivt solvärmesystem är därför att först utgå från en korrekt dimensionerad varmvattenkapacitet.Mängd varmvatten som det går att få ut från en ackumulatortank bestäms av volymen på det uppvärmda vattnet i tankens topp, temperaturen i tanken, och slingornas längd och placering.

Are empathy and compassion bad for the professional social worker?

Recent studies have shown that social workers and other professional helpers who work with traumatized individuals run a risk of developing compassion fatigue or secondary traumatic stress. Some researchers have hypothesized that helpers do this as a result of feeling too much empathy or too much compassion for their clients, thereby implying that empathy and compassion may be bad for the professional social worker. This paper investigates these hypotheses. Based on a review of current research about empathy and compassion it is argued that these states are not the causes of compassion fatigue. Hence, it is argued that empathy and compassion are not bad for the professional social worker in the sense that too much of one or the other will lead to compassion fatigue.

Real time video segmentation for recognising paint marks on bad wooden railway sleepers

Wooden railway sleeper inspections in Sweden are currently performed manually by a human operator; such inspections are based on visual analysis. Machine vision based approach has been done to emulate the visual abilities of human operator to enable automation of the process. Through this process bad sleepers are identified, and a spot is marked on it with specific color (blue in the current case) on the rail so that the maintenance operators are able to identify the spot and replace the sleeper. The motive of this thesis is to help the operators to identify those sleepers which are marked by color (spots), using an “Intelligent Vehicle” which is capable of running on the track. Capturing video while running on the track and segmenting the object of interest (spot) through this vehicle; we can automate this work and minimize the human intuitions. The video acquisition process depends on camera position and source light to obtain fine brightness in acquisition, we have tested 4 different types of combinations (camera position and source light) here to record the video and test the validity of proposed method. A sequence of real time rail frames are extracted from these videos and further processing (depending upon the data acquisition process) is done to identify the spots. After identification of spot each frame is divided in to 9 regions to know the particular region where the spot lies to avoid overlapping with noise, and so on. The proposed method will generate the information regarding in which region the spot lies, based on nine regions in each frame. From the generated results we have made some classification regarding data collection techniques, efficiency, time and speed. In this report, extensive experiments using image sequences from particular camera are reported and the experiments were done using intelligent vehicle as well as test vehicle and the results shows that we have achieved 95% success in identifying the spots when we use video as it is, in other method were we can skip some frames in pre-processing to increase the speed of video but the segmentation results we reduced to 85% and the time was very less compared to previous one. This shows the validity of proposed method in identification of spots lying on wooden railway sleepers where we can compromise between time and efficiency to get the desired result.
