Active living in municipal parks and recreation : a case study

If quality of life is an important recreation outcome, then municipal parks and recreation management's efforts have to change because:· Over one-third of all the little kids in schools will be diabetic in their lifetime if the trends we are looking at continue. The average loss of life is about 15 years, and there is an average reduction in quality oflife by about 20 years (Jackson, 2007). This thesis is about municipal parks and recreation, an agency that controls and limits physical activity opportunity. It is also about active living; from an ecological perspective, a multi-disciplinary approach to incorporate physical activity into more 111 people's daily lives. In particular, this thesis examines one case --'. the Donutville Case - . with the intent of providing an explanation of how municipal parks and recreation can advance its management efforts to improve health outcomes of people suffering from daily physical activity deficits. More specifically, how can the tension between external and internal environments to municipal parks and recreation be better balanced to affect the change needed? Given that changing the current social reality is through making decisions, decision-making functions connected with systems theory helps identify how recreation authorities can more effectively influence environmental physical activity determinants. , Sallis et al.' (2006) ·social ecological model provides the a priori focus on active living decision-making. An integrated analogous emerging logic model is developed and presented as an efficacious strategy for how municipal parks and recreation decisionmakers can affect change.

Benefits, challenges, and limitations of fair trade as a social justice movement

This thesis answers some important questions about how Fair Trade is experienced and perceived by some Northern sellers, consumers, activists, advocates, practitioners, and an importer. As it relates to sellers, I focus only on small scale independent businesses (i.e. I do not include large corporate businesses in my interview sample). Fair Trade works to establish a dignified livelihood for many producers in the South. Some of the most important actors in the Fair Trade movement are the people who buy, sell, and/or advocate for Fair Trade in the North. Fair Trade is largely a consumer movement which relies on the purchase of Fair Trade products. Without consumers purchasing Fair Trade products, retailers providing the products for sale, and activists raising awareness of Fair Trade, the movement, as it is presently constituted, would be non-existent. This qualitative research is based on 19 in-depth i.nterviews with nine interviewees involved with Fair Trade in Canada. I focus on benefits, challenges, and limitations of Fair Trade in the context of their involvement with it. I describe and analyze how people become involved with Fair Trade, what motivates them to do so, what they hope to achieve, and the benefits of being involved. I also describe and analyze how people understand and deal with any challenges and limitations associated with their involvement with Fair Trade. I also explore whether involvement with Fair Trade influences how people think about other products that they purchase and, if so, in what ways. I focus mainly on the commodity of coffee, but my discussion is not limited to this single commodity. Interviewees' experiences with and participation in Fair Trade vary in terms of their level of involvement and interest in the broader Fair Trade movement (as opposed to just participating in the market component). This research reveals that while Fair Trade is a small movement, sellers, consumers, and activists have had much success in the advancement of Fair Trade. While challenges have not deterred interviewees from continuing to participate in Fair Trade, analysis and explanation of such challenges provides the opportunity for Fair Trade practitioners to develop effective solutions in an effort to meet the needs of various Fair Trade actors.

Extending the irrelevant sound effect beyond serial recall

The finding that serial recall perfonnance for visually presented items is impaired by concurrently presented speech or sounds is referred to as the irrelevant sound effect (lSE). The foremost explanation for the effect is based on interference with rehearsal and seriation processes. The present series of experiments demonstrates tha t neither rehearsal nor seriation processes is necessary to observe the ISE. Evidence comes from three experiments that a) allow participants to report to-be-remembered items in any order, b) eliminate rehearsal by engaging participants in a cover task and surprising them with a memory test, and c) show that surprise non-serial recognition is immune to rehearsal-based experimental manipulations that modulate the ISE in more typical serial recall tasks. Together,the results show that models that rely on rehearsal or seriation processes to account for the ISE need to be reconsidered. Results are discussed in tenns of interference with encoding of to-be-remembered material.

Liquidity, institutional ownership and regulation fair disclosure

There is a body of academic literature addressing two issues of importance for leveling the playing field for all classes of investors: 1) the impact of institutional investors on liquidity; and 2) the impact of Regulation Fair Disclosure on institutional investors and liquidity. Our study addresses both issues with the purpose of attaining a better understanding and explanation of this relationship. We classify institutional ownership according to Bushee's (1998, 2001) methodology; transient institutions, dedicated institutions and quasi-indexers. Our results indicate that while transient institutions and quasi-indexers have a positive impact on liquidity, dedicated institutional ownership is negatively associated with liquidity. This result is consistent with prior theoretical studies. We also find that the effectiveness ofthe Regulation Fair Disclosure in improving liquidity is limited to firms with higher transient institutional ownership, whereas quasi-indexed institutions have not been significantly affected by the regulations. In fact, the liquidity of firms is lower for firms with higher dedicated institutional holdings, which is evidence of the "chilling effect".

Crystal Growth and Characterization of Li0.9Mo6O17

Purple bronze Li0.9Mo6O17 has attracted researchers for its low dimensionality and corresponding properties. Although it has been studied for nearly two decades, there are still some unsolved puzzles with this unique material. Single crystals of Li0.9Mo6O17 were grown using the temperature gradient flux technique in this research. The crystal growth was optimized by experimenting different conditions and good quality crystals were obtained. X-ray diffraction results have confirmed the right phase of the crystals. Resistivity measurements and magnetic susceptibility measurements were carried out, and anomalous electronic behaviors were found. All of the samples showed the metal-insulator transition near 20K, followed by behavior that differs from sample to sample: either superconducting, metallic or insulating behavior was observed below 2K. Li0.9Mo6O17 was considered as a quasi-one-dimensional crystal and also a superconducting crystal, which implies a dimensional crossover may occur at the metal-insulator transition. A two-band scenario of the Luttinger liquid model was used to fit the resistivity data and excellent results were achieved, suggesting that the Luttinger theory is a very good candidate for the explanation of the anomalous behavior of Li0.9Mo6O17. In addition, the susceptibility measurements showed Curie paramagnetism and some temperature independent paramagnetism at low temperature. The absence of any anomalous magnetic feature near 20K where the resistivity upturn takes place, suggests that a charge density wave mechanism, which has been proposed by some researchers, is not responsible for the unique properties of Li0.9Mo6O17.

Towards a better understanding of the relationship between speed of internationalization and performance outcomes among young international ventures

This thesis offers an explanation for the inconsistent relationship between speed of internationalization and performance outcomes in the context of young international ventures. We argue that the variables of scope of internationalization, entrepreneurial orientation and degree of internationalization play a moderating role in the relationship between speed of internationalization and performance outcomes of international new ventures (INVs). Using primary survey data from INVs in China, we found empirical support for significant moderating impact of scope of internationalization, entrepreneurial orientation variables and no support for the moderating impact of degree of internationalization variable. The results suggest that business managers of INVs shall consider the applied moderating variables as an effective tool kit to enhance firm performance in foreign markets and to mitigate any potential risks of early internationalization.

Functional Characterization of Monoterpenoid Indole Alkaloid (MIA) Biosynthetic Genes in Catharanthus roseus

The monoterpenoid indole alkaloids (MIAs) of Madagascar periwinkle (Catharanthus roseus) are known to be among the most important source of natural drugs used in various cancer chemotherapies. MIAs are derived by combining the iridoid secologanin with tryptamine to form the central precursor strictosidine that is then converted to most known MIAs, such as catharanthine and vindoline that dimerize to form anticancer vinblastine and vincristine. While their assembly is still poorly understood, the complex multistep pathways involved occur in several specialized cell types within leaves that are regulated by developmental and environmental cues. The organization of MIA pathways is also coupled to secretory mechanisms that allow the accumulation of catharanthine in the waxy leaf surface, separated from vindoline found within leaf cells. While the spatial separation of catharanthine and vindoline provides an explanation for the low levels of dimeric MIAs found in the plants, the secretion of catharanthine to the leaf surface is shown to be part of plant defense mechanisms against fungal infection and insect herbivores. The transcriptomic databases of Catharanthus roseus and various MIA producing plants are facilitating bioinformatic approaches to identify novel MIA biosynthetic genes. Virus-induced gene silencing (VIGS) is being used to screen these candidate genes for their involvement in iridoid biosynthesis pathway, especially in the identification of 7-deoxyloganic acid 7-hydroxylase (CrDL7H) shown by the accumulation of its substrate, 7-deoxyloganic acid and decreased level of secologanin along with catharanthine and vindoline. VIGS can also confirm the biochemical function of genes being identified, such as in the glucosylation of 7-deoxyloganetic acid by CrUGT8 shown by decreased level of secologanin and MIAs within silenced plants. Silencing of other iridoid biosynthetic genes, loganic acid O-methyltransferase (LAMT) and secologanin synthase (SLS) also confirm the metabolic route for iridoid biosynthesis in planta through 7-deoxyloganic acid, loganic acid, and loganin intermediates. This route is validated by high substrate specificity of CrUGT8 for 7-deoxyloganetic acid and CrDL7H for 7-deoxyloganic acid. Further localization studies of CrUGT8 and CrDL7H also show that these genes are preferentially expressed within Catharanthus leaves rather than in epidermal cells where the last two steps of secologanin biosynthesis occur.

The effect of different phases of synchrony on the synchrony effect

Synchronization of behaviour between individuals has been found to result in a variety of prosocial outcomes. The role of endorphins in vigorous synchronous activities (Cohen, Ejsmond-Frey, Knight, & Dunbar, 2010) may underlie these effects as endorphins have been implicated in social bonding (Dunbar & Shultz, 2010). Although research on synchronous behaviour has noted that there are two dominant phases of synchrony: in-phase and anti-phase (Marsh, Richardson, Baron, & Schmidt, 2006), research on the effect of synchrony on endorphins has only incorporated in-phase synchrony. The current study examined whether both phases of synchrony would generate the synchrony effect. Twenty-two participants rowed under three counterbalanced conditions - alone, in-phase synchrony and anti-phase synchrony. Endorphin release, as measured via pain threshold, was assessed before and after each session. Change in pain threshold during the in-phase synchrony session was significantly higher than either of the other two conditions. These results suggest that the synchrony effect may be specific to just in-phase synchrony, and that social presence is not a viable explanation for the effect of synchrony on pain threshold

Religion and Economic Growth: Was Weber Right?

Evidence of falling wages in Catholic cities and rising wages in Protestant cities between 1500 and 1750, during the spread of literacy in the vernacular, is inconsistent with most theoretical models of economic growth. In The Protestant Ethic, Weber suggested an alternative explanation based on culture. Here, a theoretical model confirms that a small change in the subjective cost of cooperating with strangers can generate a profound transformation in trading networks. In explaining urban growth in early-modern Europe, specifications compatible with human-capital versions of the neoclassical model and endogenous-growth theory are rejected in favor of a “small-world” formulation based on the Weber thesis.

On the Political Economy of Sequential Reforms

This paper proposes an explanation for why efficient reforms are not carried out when losers have the power to block their implementation, even though compensating them is feasible. We construct a signaling model with two-sided incomplete information in which a government faces the task of sequentially implementing two reforms by bargaining with interest groups. The organization of interest groups is endogenous. Compensations are distortionary and government types differ in the concern about distortions. We show that, when compensations are allowed to be informative about the government’s type, there is a bias against the payment of compensations and the implementation of reforms. This is because paying high compensations today provides incentives for some interest groups to organize and oppose subsequent reforms with the only purpose of receiving a transfer. By paying lower compensations, governments attempt to prevent such interest groups from organizing. However, this comes at the cost of reforms being blocked by interest groups with relatively high losses.

Standardized Latin and Medieval Economic Growth

Traditional explanations for Western Europe's demographic growth in the High Middle Ages are unable to explain the rise in per-capita income that accompanied observed population changes. Here, we examine the hypothesis that an innovation in information technology changed the optimal structure of contracts and raised the productivity of human capital. We present historical evidence for this thesis, offer a theoretical explanation based on transaction costs, and test the theory's predictions with data on urban demographic growth. We find that the information-technology hypothesis significantly increases the capacity of the neoclassical growth model to explain European economic expansion between 1000 and 1300.
