Http://www the effect of service determinants on customer purchase and return behavior in the online fashion industry

Burman, Louise, Stricker, Emelie January 2018 (has links)
To be present online is seen, in recent time, as a necessity for fashion companies in order to sustain on the market. Since online shopping lack the opportunity for customers to try on purchased products it entails a risk of experiencing dissatisfaction when orders are received. Through this, customers demand determinants that ensure safety within the purchase. Different kinds of customers might, however, possess various motivations for purchasing, stressing the requirements for variety in service value deliverance. Therefore, purchase and return policies comprise a significant importance in order to create attractiveness towards customers. The problem, though, consists of the balance between offering lenient purchase and return policies, to create competitiveness, but still considering excessive purchasing and depreciation of product value. There are several determinants affecting the shopping experience online. These were combined, with components of an online purchase, in a theoretical model to empirically test the key conceptual ideas embedded in the consumption system perspective. Further, primary data was conducted through company interviews and focus group interviews, with the aim to explore customer behavior online. Findings, from interviews compared with secondary data, analyzed through the theoretical model, indicates that the right of withdrawal and its additional components such as charges, time and inconvenience is interpreted differently by different customers. Further, it is up to e-tailers to discover the benefits and drawbacks of different policies in order to detect the most suited policy for them and their customers.

Social cognitive factors associated with moderate to vigorous physical activity in perimenopausal and postmenopausal women

Medema-Johnson, Heather Chi 01 May 2010 (has links)
Osteoporosis (OP) is a disease characterized by low bone mass and structural breakdown of the skeleton. The disease may be prevented through weight-bearing, moderate to vigorous physical activity (MVPA), which is important for peri- and postmenopausal women who are at great risk for OP. However, most women do not participate in activity according to guidelines, which can negatively impact bone health. A better understanding of multidimensional factors that influence MVPA may help inform physical activity interventions aiming for OP prevention. The purpose of this study was to utilize social cognitive theory (SCT) to understand the associations between social cognitive factors and MVPA among peri- and postmenopausal women. Eighty-seven peri- and postmenopausal women (aged 43 to 65) completed this study. Participants completed demographic, health, calcium, and SCT questionnaires. SCT variables assessed included task self-efficacy (SET) and barrier self-efficacy (SEB), perceived social support from friends (SSFR) and family (SSFA), and perceived access to facilities (ACF) and home equipment (ACH). Participants wore an NL-1000 pedometer for one week to assess total steps per day and minutes spent in MVPA. Past year MVPA, past week leisure MVPA, and past week occupational/ transport MVPA were assessed with the Modifiable Activity Questionnaire. Stepwise regression analysis was used to identify the direct relationships between cognitive variables and each of the physical activity outcome measures. Moderation-mediation analysis was conducted to determine if significant interaction effects or confounding effects existed between social cognitive variables and each physical activity variable. Age, income, BMI, and highest level of education were controlled for in all analyses. Results showed significant relationships between social cognitive factors and each physical activity outcome, supporting the use of such variables for understanding physical activity behavior in peri- and postmenopausal women. For steps per day and MVPA minutes per day, 32% and 26% of the variance in activity was explained. For past year MVPA, past week leisure MVPA, and occupational/ transport MVPA, 39%, 26%, and 27% of the variance in activity was explained, respectively. The combination of variables entering the models was different for each physical activity outcome, but overall, SEB consistently emerged as the most prominent factor. Moderation analyses revealed a three way interaction effect between SEB, SSFR, and ACF for steps per day, and two-way interaction effects between SEB and SSFR for past year MVPA and past week leisure MVPA. Mediation analysis indicated SSFA confounded the relationship between SEB and past year MVPA. Results of this study indicate social cognitive factors are directly and indirectly associated with total and MVPA in peri- and postmenopausal women. These relationships should be considered when aiming to develop physical activity intervention programs for prevention of OP in peri- and postmenopausal populations.

Psychosocial Determinants of Elective Cesarean Section Deliveries in Selected Obstetric Facilities in Nairobi, Kenya

Oguta, Tom Joseph 01 January 2015 (has links)
Cesarean section (CS) rates have generally increased across the world in the past decade. Reducing elective cesarean section (ECS) rates is imperative as many countries aim to maintain threshold CS rates at or below 15%, the level recommended by the United States' National Institutes of Health. Women are believed to consider ECS for various interconnected psychosocial reasons, but few quantitative studies have investigated these factors. This prospective cohort study was based on the social ecological model (SEM) and the theory of planned behavior (TPB) models, and identified the psychosocial predictors of ECS among 1,268 expectant women in 2 hospitals in Nairobi. Participants completed a structured questionnaire consisting of 10 validated psychosocial scales and were followed for actual mode of delivery (MoD) from hospital records and postnatal telephone interviews. The overall prevalence of CS and ECS were 16.0% and 6.4%, respectively; the CS rate was not statistically higher than the recommended 15% (p > 0.05). The combined CS incidence rate for these 2 hospitals was 83 per 1,000 births per month. Autonomy, fear of childbirth, pregnancy related anxiety, perceived social support from friends, and outcome expectancy for birth were statistically significant predictors of ECS, given the parity and age at first pregnancy, Ï?2(df = 19) = 77.735, p

Welcome to the Neighborhood, Tech

Gutierrez, Maya 01 January 2019 (has links)
Casual empiricism suggests that the arrival of a major technology company into an area has the ability to transform the local economy. I examine the economic impact on residential real estate rental prices by the opening of offices by four of the top technology companies—Apple, Facebook, Google, and Microsoft. Rents are about 2.8% lower in metropolitan areas with top technology company presence compared to metropolitan areas without top technology company presence. Taking this economic outcome into account may influence the public and policymakers’ willingness to give tax breaks and other incentives to attract major technology companies.

Antenatal Care and Maternal Sociocultural Determinants of Childhood Immunization in Northern Nigeria

Okafor, Amaka Tonia 01 January 2019 (has links)
Immunization has been recognized globally as a cost-effective public health intervention. However, despite its benefits, children in northern Nigeria are still adversely affected by the negative consequences of inadequate uptake of immunization. The purpose of this study was to assess antenatal care and maternal sociocultural determinants that influence childhood immunization within 2 months of birth in northern Nigeria. Constructs of social cognitive theory were applied to this retrospective correlational cross-sectional inquiry involving women 15-49 years old in northern Nigeria. Secondary data (the 2013 Nigeria Demographic and Health Survey) were analyzed using univariate, bivariate and multivariate logistic regression. Statistically significant (p < 0.05) predictors of uptake of childhood immunization within 2 months of birth were the person who delivered antenatal care, the number of antenatal care visits, the number of tetanus injections, maternal educational level, religion, wealth index, husband/partner educational level, and the person who decides on health care. Educated Christian women from middle-class or rich homes, whose husbands/partners were also educated and who jointly decided on health care, made numerous contacts with health care professionals, and received at least one tetanus injection during antenatal care, had a higher likelihood of immunizing their children within 2 months of birth. The positive social change implications for this study include providing evidence of deterrents to childhood immunization that could lead to relevant policies and interventions leading to healthier children, communities, and society.

Determinants of Low Birth Weight in a Population-Based Sample of Zimbabwe

Nesara, Paul 01 January 2018 (has links)
Low birth weight (LBW) is a major public health concern globally. Despite its negative social and economic impact on the family and community at large, it has remained relatively unexplored at population level in Zimbabwe. The purpose of the study was to establish determinants of LBW using data from the 2015 Zimbabwe Demographic and Health Survey. The socioecological model was the conceptual framework for the study. A secondary analysis was conducted on 4,227 mother-infant dyads. Independent variables were duration of pregnancy, number of births within the past 5-year period, exposure to mass media, type of fuel used for cooking in the household, and intimate partner violence. Covariates were maternal age at delivery, place of residence, anemia, marital status, education, wealth index, ever terminated pregnancy, infant sex, and alcohol consumption. For parsimony, statistical significance was set at p < 0.05 at the 95% confidence interval (CI). Multivariable logistic regression analysis showed that mild maternal anemia (adjusted odds ratio [aOR] 1.83 CI 1.17-2.87 p = 0.01), moderate to severe anemia (aOR 1.80 CI 1.01-3.19 p = 0.05), and being a female neonate (aOR 1.48 CI 1.17-2.87 p = 0.008) had higher odds for LBW. Pregnancy duration of 8 months (aOR 0.01 CI 0.003-0.039 p < 0.001) and of 9 months (aOR 0.12 CI 0.04-0.33 p = 0.001) had lower odds for LBW. Birth of 2 infants within a 5-year period (aOR 2.40 CI 1.24-4.66 p = 0.01) was associated with LBW. Implications for positive social change include coming up with a health policy on the management of anemia during pregnancy and health promotion messages to promote optimal birth spacing, including strategies that reduce chances for preterm deliveries.

HIV Prevalence Determinants Among Young People in Zimbabwe: Sexual Practices Analysis

Mphaya, Joyce Caroline 01 January 2017 (has links)
A decline in Human Immunodeficiency Virus (HIV) prevalence rates have been observed among females ages 15 to 19 years and 20 to 24 years in Zimbabwe between 2005 and 2010. However, for males 15 to 19 years, rising trends were observed, whereas for males ages 20 to 24 years, rates fluctuated between 2005 and 2011. The purpose of this cross-sectional study was to examine relationships between sexual behaviors and practices and HIV prevalence among young males and females ages 15 to 24 years in Zimbabwe. Guided by constructs of proximate determinants framework, extracted data from two National Demographic Health surveys of 2005/06 and 2010/11 were analyzed using chi square and binary logistic regression. This study revealed that sexual practices, relationship status, and education status increase the odds of being HIV positive differently among 15 to 19-year-olds and 20 to 24-year-olds based on gender and changes through time. Significant relationship existed between HIV positive serostatus and total number of life time partners among females 15 to 19 years and 20 to 24 years; lack of condom use among males 20 to 24 years in 2005/06; early sexual debut and lower education status among females 20 to 24 years; and being widowed, separated, or divorced among males and females 20 to 24 years in 2010/11. The Odds of being HIV positive for males ages 15 to 19 years was not predicted by sexual practice, creating a need for future study. This study can contribute to positive social change by providing information about the associations between HIV serostatus and the assessed risk factors, which may help promote awareness about HIV infection risk, thereby helping develop and implement targeted public health interventions to reduce the burden of HIV.

A Linear Programming Analysis of Several Determinants of Profit on a Simulated Northern Utah Dairy Farm

Atwood, Jay Dee 01 May 1983 (has links)
The purpose of the study was to analyze several determinants of profit on a simulated northern Utah dairy farm. A linear programming model was developed to accomplish this. Optimal conditions on the farm were estimated and then other model applications were made to evaluate the importance of milk price, cropland ownership, and corn silage production and feeding. The significance of cow quality also was estimated. Optimal conditions on the farm gave rates of return to capital between savings rates and loan rates obtainable at a financial institution. Marginal values derived for land did not support the current asking price of land. The marginal values derived for cows would support higher levels of investment in the cows than current prices of the cows. Optimal crop mixes and rations also were derived. Milk price had a direct effect on financial measures of the farm's well-being. Increasing herd size was found to be a logical response to a decrease in milk price. Cropland ownership had an inverse effect on returns but a direct effect on annual income. Corn silage production was found to be more important for a poorer herd than a better herd. However, corn silage production and feeding had a near neutral effect on measures of financial well-being.

Development and structuring of commercial mortgage-backed securities in Australia

Chikolwa, Bwembya C January 2008 (has links)
According to the Reserve Bank of Australia (2006) the increased supply of Commercial Mortgage-Backed Securities (CMBS), with a range of subordination, has broadened the investor base in real estate debt markets and reduced the commercial property sector’s dependence on bank financing The CMBS market has been one of the most dynamic and fastest-growing sectors in the capital markets, for a market which was virtually nonexistent prior to 1990. The global CMBS market issuance which stood at AU$5.1 billion (US$4 billion) in 1990 had grown to AU$380 billion (US$299 billion) by the end of 2006. In Australia, a total of over 60 CMBSs with nearly 180 tranches totalling over AU$17.4 billion had been issued to December 2006 from when they were first introduced in 1999. To date few studies have been done on Australian CMBSs outside the credit rating agency circles. These studies are predominantly practitioner focused (Jones Lang LaSalle 2001; Richardson 2003; Roche 2000, 2002). O’Sullivan (1998) and Simonovski (2003) are the only academic studies on CMBSs. As such, this thesis examines issues relating to the development of Australian CMBSs and quantitatively and qualitatively analyses the structuring of Australian CMBSs. In assessing the growth of the Australian CMBS market, an interpretive historical approach (Baumgarter & Hensley 2005) is adopted to provide a cogent review and explanation of features of international and Australian CMBSs. This helps to understand the changing nature of the market and provides better understanding of the present and suggests possible future directions. The Australian CMBS market is matured in comparison with the larger US and EU CMBS markets as seen by the diversity of asset classes backing the issues and transaction types, tightening spreads, and record issuance volumes. / High property market transparency (Jones Lang LaSalle 2006b) and predominance of Listed Property Trusts (LPT) as CMBS issuers (Standard & Poor’s 2005b), who legally have to report their activities and underlying collateral performance to regulatory regimes such as Australian Stock Exchange (ASX)/Australian Securities and Investment Commission (ASIC) and their equity partners, have contributed to the success of the Australian CMBS market. Furthermore, the positive commercial real estate market outlook should support future CMBS issuance, with LPTs continuing their dominance as issuers. In investigating property risk assessment in Australian CMBSs, all the CMBSs issued over a six year period of 2000 to 2005 were obtained from Standard and Poor’s presale reports as found in their Ratings Direct database to identify and review how property risk factors were addressed in all issues and within specific property asset classes following the delineation of property risk by Adair and Hutchinson (2005). Adequate assessment of property risk and its reporting is critical to the success of CMBS issues. The proposed framework shows that assessing and reporting property risk in Australian CMBSs, which are primarily backed by direct property assets, under the headings of investment quality risk, covenant strength risk, and depreciation and obsolescence risk can easily be done. The proposed framework should prove useful to rating agencies, bond issuers and institutional investors. Rating agencies can adopt a more systematic and consistent approach towards reporting of assessed property risk in CMBSs. Issuers and institutional investors can examine the perceived consistency and appropriateness of the rating assigned to a CMBS issue by providing inferences concerning property risk assessment. / The ultimate goal of structuring CMBS transactions is to obtain a high credit rating as this has an impact on the yield obtainable and the success of the issue. The credit rating process involves highly subjective assessment of both qualitative and quantitative factors of a particular company as well as pertinent industry level or market level variables (Huang et al. 2004), with the final rating assigned by a credit committee via voting (Kwon et al. 1997). As such, credit rating agencies state that researchers cannot replicate their ratings quantitatively since their ratings reflect each agency’s opinion about an issue’s potential default risk and relies heavily on a committee’s analysis of the issuer’s ability and willingness to repay its debt. However, researchers have replicated bond ratings on the premise that financial ratios contain a large amount of information about a company’s credit risk. In this study, quantitative analysis of determinants of CMBS credit ratings issued by Standard and Poor’s from 2000 – 2006 using ANNs and OR and qualitative analysis of factors considered necessary to obtain a high credit rating and pricing issues necessary for the success of an issue through mail surveys of arrangers and issuers are undertaken. Of the quantitative variables propagated by credit rating agencies as being important to CMBS rating, only loan-to-value ratio (LTV) is found to be statistically significant, with the other variables being statistically insignificant using OR. This leads to the conclusion that statistical approaches used in corporate bond rating studies have limited replication capabilities in CMBS rating and that the endogeneity arguments raise significant questions about LTV and debt service coverage ratio (DSCR) as convenient, short-cut measures of CMBS default risk. / However, ANNs do offer promising predictive results and can be used to facilitate implementation of survey-based CMBS rating systems. This should contribute to making the CMBS rating methodology become more explicit which is advantageous in that both CMBS investors and issuers are provided with greater information and faith in the investment. ANN results show that 62.0% of CMBS rating is attributable to LTV (38.2%) and DSCR (23.6%); supporting earlier studies which have listed the two as being the most important variables in CMBS rating. The other variables’ contributions are: CMBS issue size (10.1%), CMBS tenure (6.7%), geographical diversity (13.5%) and property diversity (7.9%) respectively. The methodology used to obtain these results is validated when applied to predict LPT bond ratings. Both OR and ANN produce provide robust alternatives to rating LPT bonds, with no significant differences in results between the full models of the two methods. Qualitative analysis of surveys on arrangers and issuers provides insights into structuring issues they consider necessary to obtain a high credit rating and pricing issues necessary for the success of an issue. Rating of issues was found to be the main reason why investors invest in CMBSs and provision of funds at attractive rates as the main motivation behind CMBS issuance. Furthermore, asset quality was found to be the most important factor necessary to obtain a high credit rating supporting the view by Henderson and ING Barings (1997) that assets backing securitisation are its fundamental credit strength. / In addition, analyses of the surveys reveal the following: • The choice of which debt funding option to use depends on market conditions. • Credit tranching, over-collateralisation and cross-collateralisation are the main forms of credit enhancement in use. • On average, the AAA note tranche needs to be above AU$100 million and have 60 - 85% subordination for the CMBS issue to be economically viable. • Structuring costs range between 0.1% – 1% of issue size and structuring duration ranges from 4 – 9 months. • Preferred refinancing options are further capital market issues and bank debt. • Pricing CMBSs is greatly influenced by factors in the broader capital markets. For instance, the market had literary shut down as a result of the “credit crunch” caused by the meltdown in the US sub-prime mortgage market. These findings can be useful to issuers as a guide on the cost of going to the bond market to raise capital, which can be useful in comparing with other sources of funds. The findings of this thesis address crucial research priorities of the property industry as CMBSs are seen as a major commercial real estate debt instrument. By looking at how property risk can be assessed and reported in a more systematic way, and investigating quantitative and qualitative factors considered in structuring CMBSs, investor confidence can be increased through the increased body of knowledge. Several published refereed journal articles in Appendix C further validate the stature and significance of this thesis. It is evident that the property research in this thesis can lead aid in the revitalisation of the Australian CMBS market after the “shut down” caused by the melt-down in the US sub-prime mortgage market and can also be used to set up property-backed CMBSs in emerging countries where the CMBS market is immature or non-existent.
