Provincial governments across Canada rely on regeneration requirements and penalties to promote reforestation following harvesting. However, little has been written on how to determine optimal levels of penalties for noncompliance such that tenure holders have incentives to further social reforestation objectives. This paper shows how reforestation penalties may be calculated in the case of Alberta. The calculation of the penalty is shown to be dependent on (i) changes in the values of future annual allowable cuts caused by failure to promptly regenerate, (ii) the portion of stumpage values collected with stumpage fees, (iii) nontimber values influenced by reforestation, (iv) differences in private and social discount rates, (v) costs of detecting noncompliance, and (vi) the probability of detecting infractions. In the case of Alberta, (v) and (vi) are minor considerations, as detection costs are low and probability of detection is high. However, values of (i) through (iv) have large potential impacts on the optimal penalties. For example, if (i) annual allowable cuts drop by 99 m3 for a 3-year reforestation delay (vs. an acceptable 2-year delay) on a 783-ha forest, (ii) stumpage fees are $10 below stumpage value, (iii) nontimber values are zero, and (iv) the private discount is 9%, while the social rate is 6%, then the optimal penalty is $49.17CAN·ha–1. However, if we change (ii) and (iv) such that stumpage fees are $30CAN below stumpage value and the private discount is 9%, while the social rate is 3%, then the optimal penalty is $168.58CAN·ha–1. With zero nontimber values, zero monitoring costs, no divergence between public and private interest rates at 9%, and a probability of detection of 1.00, the current penalty of $30CAN·ha–1·year–1 would approximate the optimal amount if stumpage fees were $20CAN·m–3. The variability in values of (i) through (iv) across forests and over time suggests that problems will arise in establishing a constant penalty for all provincial forests and that penalties should be revised as values change over time.

Abstract This article offers a brief introduction to the most frequent type of inscription: funerary inscriptions or epitaphs. The article offers a chronological overview from the Archaic period to late Antiquity, with an emphasis on Athens. It opens with a brief discussion of the archaeological and ritual contexts in which funerary inscriptions were set up, followed by a discussion of archaic epigrams and the social strategies that lay behind them. This is followed by a discussion of public and private graves that shows how epigraphic habits changed over time. The article continues with a discussion of funerary epigraphic habits outside Athens and closes with a few examples of Christian epitaphs.

<p>For years, understanding the relationship between behaviour and cognition has been a central concern of research conducted in the social sciences. In fields as diverse as anthropology, business, medicine, and education it is widely accepted that the development of practice (as a type of behaviour), depends on a precise understanding of how thought gets carried into action. However, studies investigating the complex interplay between a learner’s cognition (i.e. thoughts, knowledge, beliefs, and feelings about L2 learning) and their behaviour (i.e. language-related activity) are only recently garnering attention. In addition, only few studies have looked at this dynamic process with adult participants beyond the language learning classroom. Framed within the context of naturalistic language learning, this investigation explores the social construction of adult (over 30 years of age) L2 learners’ cognition in an ESOL setting. Specifically it aimed to answer the following research questions:  RQ 1. What are the prior language learning experiences of a group of adult migrant learners living in New Zealand?  RQ 2. How have these prior language learning experiences influenced the construction and development of their beliefs, assumptions, knowledge (BAK) about language learning?  RQ 3. What is their perceived need for English in their current socio-cultural context?  RQ 4. How do adult migrant language learners engage in language related activities beyond the classroom?  RQ 5. How can this language learning behaviour be reflected in a model of language learner cognition?  The study combined a longitudinal, ethnographic approach, with elements of narrative and case study inquiry. Six ‘recently arrived’ (Dunstan, Roz, & Shorland, 2004a) Colombian migrants (five refugees; one immigrant) were asked to talk about and discuss both prior and current experiences learning and using an L2. Through these lengthy in-depth, conversation-like interviews conducted in Spanish (the participants’ L1), told over time, a nuanced picture of the participants’ L2-related cognition emerged. As a result, I was able to more clearly observe the dynamic process in which a language learner’s mental life both impacts and is impacted on by language-related activity throughout their day-to day interactions. The participants are seen engaging in the L2 across a range of settings including at home, the doctor’s office, supermarkets and work. Moreover, in their accounts of this engagement we see change and revision (i.e. development) in their thinking about L2 learning and themselves as language learners, as well as their feelings toward the L2, other L2s and L2 users. A single participant was selected as an exemplary case to examine in detail, and facilitate understanding of this development. A case study approach allowed for a more intricate exploration of how the interplay between thought, emotion, and context impacted on the learner’s approaches to language-related activities. Issues regarding readiness to interact in the L2, intelligibility, language variety, and aversion to the ‘sound of English’ were seen as playing significant roles in the learner’s language development. This analysis resulted in the construction of a framework depicting language learner cognition in action. In terms of implications, this research supports the case for more qualitative research in SLA which centres learners’ perspectives of their L2 related experiences, particularly when so much of what seems to be affecting learning is the learners understanding of themselves and their actions. It also argues that studies in L2 cognition should focus their investigations on the developmental processes involved in the social construction of the mental factors which impact language learning and use. Finally, while belief studies in SLA are expanding the scope of their investigations – by looking to include more emotion and other affective factors, as well as by branching out into self-related constructs such as self-concept and self-efficacy in the foreign language domain – these studies remain limited in their almost microscopic view of learners’ mental lives. The picture of cognition I offer provides a more holistic understanding of this phenomenon which helps account at a macro-level for L2 behaviour. The study also highlights the potential and power of data gathering methods which foreground the participants’ voices and ideas (i.e. in-depth, unstructured interviews told over time) – reminding us that it is important when looking for what drives language learning behaviour to consider what the learners feel and think.</p>

&lt;p&gt;The social discount rate is a crucial element required for valuing future damages from climate change. A consensus has emerged that discount rates should be declining with horizon, i.e., that the term structure of discount rates should have a negative &lt;em&gt;slope&lt;/em&gt;. However, much controversy remains about the appropriate the overall &lt;em&gt;level&lt;/em&gt; of discount rates.&lt;/p&gt;&lt;p&gt;We contribute to this debate from a macro-finance perspective, based on the insight that the equilibrium real interest rate, commonly known as r*, is the crucial determinant of the level of discount rates. First, we show theoretically how r* anchors the term structure of discount rates, using the modern macro-finance theory of the term structure of interest rates to provide a new perspective on classic results about social discount rates. Second, we show empirically that new macro-finance estimates of r* have fallen substantially over the past quarter century---consistent with a broader literature that documents such a secular decline. Bayesian estimation of a state-space model for Treasury yields, inflation and the real interest rate allows us to quantify both the decline in r* and the resulting downward shift of the term structure of social discount rates. Third, we document that this decline in r* and the social discount rate boosts the social cost of carbon and has quantitatively important implications for assessing the economic consequences of climate change. In essence, we demonstrate that the lower new normal for interest rates implies a higher new normal for the present value of climate change damages.&lt;/p&gt;

Narrative theorists have long recognised that narrative is a selective mode of representation. There is always more than one way to tell a story, which may alter according to its teller, audience and the social or historical context in which the story is told. But multiple versions of the ‘same’ events are not always valued in the same way: some versions may become established as dominant accounts, whilst others may be marginalised or resist hegemony as counter narratives (Bamberg and Andrews, 2004). This essay explores the potential of Wikipedia as a site for positioning counter and dominant narratives. Through the analysis of linearity and tellership (Ochs and Capps, 2001) as exemplified through revisions of a particular article (‘Murder of Meredith Kercher’), I show how structural choices (open versus closed sequences) and tellership (single versus multiple narrators) function as mechanisms to prioritise different dominant narratives over time and across different cultural contexts. The case study points to the dynamic and relative nature of dominant and counter narratives. In the ‘Murder of Meredith Kercher’ article the counter narratives of the suspects’ guilt or innocence and their position as villains or victims depended on national context, and changed over time. The changes in the macro-social narratives are charted in the micro-linguistic analysis of structure, citations and quoted speech in four selected versions of the article, taken from the English and Italian Wikipedias.

The social rate of discount is a crucial driver of the social cost of carbon (SCC), that is, the expected present discounted value of marginal damages resulting from emitting one ton of carbon today. Policy makers should set carbon prices to the SCC using a carbon tax or a competitive permits market. The social discount rate is lower and the SCC higher if policy makers are more patient and if future generations are less affluent and policy makers care about intergenerational inequality. Uncertainty about the future rate of growth of the economy and emissions and the risk of macroeconomic disasters (tail risks) also depress the social discount rate and boost the SCC provided intergenerational inequality aversion is high. Various reasons (e.g., autocorrelation in the economic growth rate or the idea that a decreasing certainty-equivalent discount rate results from a discount rate with a distribution that is constant over time) are discussed for why the social discount rate is likely to decline over time. A declining social discount rate also emerges if account is taken from the relative price effects resulting from different growth rates for ecosystem services and of labor in efficiency units. The market-based asset pricing approach to carbon pricing is contrasted with a more ethical approach to policy making. Some suggestions for further research are offered.

Through the case study of Amazon Ring's cameras, this paper explores the deepening material and discursive alliance between public and private institutions in the building of digital infrastructures that support the development of community surveillance. The analysis reveals a complex supply-chain network entangled with histories of settler-colonialism, racialization and gendered inequities. Bolstered by developments in cloud computing, concealing the human and nonhuman supply-chains, these systems are never detached from material inputs; rather, they are embedded in vast infrastructural systems and complex transnational supply chains powered by logics of extraction, circulation and accumulation of capital. I argue that Amazon Ring cameras are an articulation of “infrastructural power” defined by Laleh Khalili (2018: 915) as an assemblage of “practices, discourses, physical fixtures, laws and procedures” with the aim of (re)producing capitalist relations. Through a material and discursive analysis, this paper aims to draw into the light the complex human and non-human entanglements that constitute community surveillance networks in order to move towards an infrastructural critique so that we may more effectively evaluate the social costs of digital systems that can never be detached from their material and human creators.

The embodied technical change should reduce the cost of production of the commodity. However, price structure, wages and interest rates also will change over time. Thus if a commodity is following a fixed price regime, the adjustment of a historical input-output table to current price wage level will leaves less and less profit per unit of output. The extent of this reduction will indicate the extent of technological change. There are different approaches to the prediction of changes in input-output coefficients. The first approach, attributable to Leontief (1941) and Stone (1962), assumes that input-output matrices change over time in a “biproportional” way. The other approach is to estimate trends in individual coefficients using statistical data. Former approach is used by a number of experts, including Fontela, et al. (1970), Almon, et al. (1974) and Carter (1970). Arrow and Hoffenberg (1959), Henry (1974), Savaldson (1970, 1976), Ozaki (1976), Aujac (1972) and Buzunov (1970). These are examples of the application of the quantitative approach for forecasting input-output coefficients. Still another approach which could not get much attention for forecasting input-output coefficients, is constructing the marginal input-output coefficients [Tilanus (1967); Middelhoek (1970)]. Marginal coefficients for forecasting constructed by Tilanus and Middelhoek are based on average input-output tables, which shows that still new approach (marginal) is based on the old (average) one

This study is mainly based on conducted naturalistic descriptive observation of 13 children ages 6&ndash;8 years using open-ended materials in their play at the Creative Play Club (CPC). The research carefully examines and analyzes how four boys and nine girls in the CPC used open-ended materials in their play over 8 weeks. One aim was to evaluate changes in the quality of play over time. A second aim was to analyze the influence of various factors on children&rsquo;s social and nonsocial play behaviors. Those factors were the materials&rsquo; characteristics and affordances and the social activity setting. The research gave special attention to the possible influences that flatten expression in play and those influences that might reignite play expression within or across CPC sessions. The research generated evidence that children&rsquo;s drawing, manipulating objects, and reflecting are meaning making. Interpretations of data were guided by an activity setting model, affordance theory, and a multimodality and meaning-making conceptual framework. The main findings were that the CPC and the case study are good conduits for exploring the possibilities and challenges that emerge from children&rsquo;s experiences with open-ended materials in play with other children.

Opening ParagraphOne of the more interesting historiographical debates that emerged in the course of the great burst of research into Akan (actually primarily Asante) history during the 1950s and 1960s concerned the ‘structure’ of the Asante empire, or ‘Greater Asante’ as one of the contributors to the debate, Kwame Arhin, has termed it (Arhin, 1967). The debates have largely been informed by a synchronic, ‘centrist’ approach; that is, by an approach that views the imperial structure at a given point in time, and primarily from the perspective of the political centre, the capital town of Kumase. The 1970s have seen a proliferation of regional studies of the Akan and their neighbours, and so it is perhaps time to reopen the debate on the nature of the Asante imperial order from a broader perspective, one that is both more sensitive to change over time and includes the emerging views from the periphery (see, for example, Berberich, 1974; Case, 1979; Ferguson, 1972; Greene, 1981; Haight, 1981; Handloff, 1982; Sanders, 1980; Weaver, 1975; Yarak, 1976). The present paper first briefly sketches the social and political setting in nineteenth-century Elmina (εdena), then critically reviews the historiographical debate over the structure of Greater Asante, and lastly offers an alternative approach to the study of Greater Asante based on a case study of the history of Asante relations with Elmina.
