This dissertation examines two problems retailers face when assessing their marketing resource allocation. In the first chapter, I develop a conceptual framework and modeling approach to help retailers assess how online and offline marketing effectiveness vary by channel, customer value segment, and country. In the main application, using a retail dataset from six countries, I estimate Hierarchical Linear and Cross-Random Effects models to find that own- and cross-channel sales responsiveness to online and offline marketing varies by value segment and country. Specifically, direct mail drives offline sales for prospects cross all countries and email drives both online and offline sales across customer segments in half of the countries. Customer value is the key driver of offline sales, while country is a key driver of online sales. I validate the findings with a second retail dataset and a field experiment. The different elasticities and customer segment sizes across countries imply a different marketing resource allocation from status-quo. The findings generate actionable implications for theory and managers. In the second chapter, I quantify the simultaneous effects of customer satisfaction (CS) and employee satisfaction (ES) on cross-buying. I jointly model the effects of CS and ES on cross-buying probability controlling for customer heterogeneity and time effects. The model accounts for nonlinear and asymmetric effects of satisfaction. Moreover, I examine whether the effects of CS and ES on cross-buying are non-monotonic. I employ panel datasets at individual customer and employee level on transactions and satisfaction of a leading car rental company. The results of the empirical analysis lead to four main findings. First, CS and ES have simultaneous effects on cross-buying probability. Second, the effect size of ES is about 2.7 times larger than the effect of CS. Third, the relationship between satisfaction and cross-buying is concave non-monotonic. For low satisfaction levels, an increase in satisfaction leads to higher cross-buying. However, for high levels of satisfaction, an increase in satisfaction leads to lower cross-buying. Fourth, CS and ES do not have an interaction effect on cross-buying probability.

This thesis is composed of three chapters that form two parts. The first part is composed of two chapters and studies problems related to the exotic option market. In the first chapter we are interested in a numerical problem. More precisely we derive closed-form approximations for the price of some exotic options in the Black and Scholes framework. The second chapter discusses the construction of multivariate Lévy processes with and without stochastic volatility. The second part is composed of one chapter. It deals with a completely different issue. There we will study the problem of individual and temporal aggregation in panel data models.

Abstract The Embedded controls panel belongs to the components, in the terminal product overhead construction, forever is a supporting role, but actually is occupying the indispensable core status. Under division of labor system, in view of the fact that the product characteristic, the system industry cannot meddle in the design and the manufacture, also because its may the support be widespread, is industry which belongs specialized also may independently develop. Technical progress, effective promotion technology with producing energy, but has an inevitable phenomenon, will be in this stage that supply will surpass demand, but attacks each industry. The Embedded control panel industry not exceptional entered the Warring States time, the potential has certainly to have many physique to be worse, to be unable properly to adjust the suitable same business to be able to swallow in competition sea. This tendency is unable to keep off, where but doesn't have red sea to have the blue sea, the crisis is the favorable turn time, starts an undertaking leader which has not been able to become the market, now actually also is becomes market Challenger the turning point. Company's energy is limited, must the effective utilization, therefore must be able thoroughly understand the market, discovered customer's real demand, the fixed industry development tendency, according to strengthens the company competitive ability, it can stand in this market to the invincible position, in is stable strives for the development. Is the management essence in the layout, how this research goal repeatedly carefully examining the market, the product and the customer after the discussion document company, draws up the effective feasible whole development strategy, again penetrates the company interior the reform, of competitive ability the strengthened product, innovates, uniquely promotes good reputation in the global Embedded controls panel competitive market. The research the main conclusion is as follows: 1. Penetrates the market investigation, the product, the customer behavior pattern repeatedly discussion, draws up the company whole development strategy, is clear about the limits enterprise to manage the pattern and the development direction. 2. To in affiliation by the management technique, the realization company is basic and the core competitive ability constructs the construction, the promotion enterprise manages the physique. 3. Foreign rests on the global layout strategy plan, the coordinate product life cycle management, vertical and operation horizontal marketing, steady expands the enterprise domain.

This thesis explores two hybrid systems employing a core material reinforced by an external skin, namely, cladding walls composed of polyurethane foam core sandwiched between fibre-reinforced polymer (FRP) skins, and beams composed of concrete-filled FRP or steel tubes. The walls were studied in two phases. In phase I, the polyurethane foam core was injected between two carbon-FRP (CFRP) skins. Ten panels were tested to investigate their structural performance and failure modes. Test parameters included quality control in terms of reproducibility of test results, moment-shear ratio, and the orientation of an architectural masonry-like coating. The study showed that design is governed by stiffness and not strength and that the CFRP was underutilized. Also, quality control was shown to be poor for this method of fabrication. As such, in phase II, ten panels were fabricated by laminating glass-FRP (GFRP) skins to prefabricated polyurethane foam blocks. Similar flexural testing was carried out to investigate two different densities of foam, and moment-shear ratio. The study showed evidence of high quality control and that the density of the foam core significantly affected flexural capacity and stiffness. Rectangular concrete-filled tubes (CFTs), with either steel or pultruded GFRP tubes were fabricated and tested as beams in three-point bending, at different shear span-to-depth (a/d) ratios of 1 to 5 to examine crack patterns, strength and failure modes. It was shown that the critical (a/d) ratio, at which moment capacity drops, is between 4 and 5 for CFTs with GFRP tubes and between 1 and 2 for CFTs with steel tubes. It was also shown that ductility is drastically reduced at (a/d) ratios below 3 for steel tubes. Crack pattern and size were highly dependent on the magnitude of slip between the concrete and tube. A major full depth flexural crack developed in all CFTs with GFRP tubes. However, when internal steel rebar was added, major diagonal cracks were formed in addition to fine flexural cracks. In CFTs with steel tubes, fine flexural cracks developed, except at a/d = 1, where fine diagonal cracks were predominant. A strut-and-tie model was developed and provided reasonable agreement with test results. / Thesis (Master, Civil Engineering) -- Queen's University, 2008-12-23 12:25:09.685

Concrete-Insulation-Concrete Sandwich Panels with Glass Fibre Reinforced Polymer (GFRP) shear connectors can be a solution to increasing energy efficiency in building envelopes, while also providing many architectural, structural, and economic benefits for building designs. This study consists of extensive experimental investigation of the shear and thermal properties of a unique sandwich panel design, incorporating GFRP shear connectors and a concrete “stud” system. The goal of this study is to expand upon the knowledge of alternative connectors’ effect on structural and thermal properties of sandwich panels, and to develop a thermally, structurally, and economically efficient panel. In the structural phase fifty 254x254x900 mm specimens representing segments of the precast sandwich wall, comprising two concrete wythes and a concrete stud surrounded by insulation foam, were tested in a double shear configuration. Three types of GFRP connectors produced from available sand-coated and threaded rods were tested and compared to conventional steel and polymeric connectors. GFRP connector diameters varied from 6 to 13 mm, and spacing varied from 80 to 300 mm. Both circular and rectangular cross-sections were examined, along with various end treatments to compare with simple straight embedment. The shear strength of GFRP connectors ranged from 60 to 112 MPa, significantly higher than polymeric connectors but lower than steel connectors. As the connectors bridged a small gap of insulation between the concrete wythe and stud, their shear strength was lower than manufacturer reported values due to the presence of some bending. Varying the size, spacing, cross-section shape or end treatment of connectors had insignificant effect on their strength. The connectors failed by longitudinal delamination then transverse shear, but did not pull out of the concrete wythe. Adhesion bond between concrete and insulation was significant and contributed about 28% of resistance, but was too variable for use in design. In the thermal testing phase, ten 254x1550x2400 full-scale specimens were tested in a purpose-built hot box apparatus under steady-state conditions. GFRP connectors showed minimal thermal bridging regardless of cross-section area or spacing, while steel connectors demonstrated significant thermal bridging in recorded temperatures despite a smaller cross-section area, and were clearly visible in thermal imaging. / Thesis (Master, Civil Engineering) -- Queen's University, 2014-05-06 13:32:38.896
