Correlation between gross domestic product,utilization of in vitro fertilization,and pregnancy success rate across the world

Abstract

Background: IVF is now a wide spread procedure globally, and currently 65 countries report annually all or part of their IVF/ICSI cycles, from which the International Committee Monitoring progress in Assisted Reproduction Technology (ICMART) published its report. There is considerable variation in the utilization (number of cycles per population) globally.

Aims: The objectives of this study were to assess whether utilization is related to national wealth, presented as gross domestic product (GDP), and whether the GDP has any effect on success in IVF treatment, mainly delivery and clinical pregnancy rates.

Results: The results demonstrated a significant positive correlation between utilization and GDP (CC = 0.563, p?=?0.00000194), and both utilization and GDP have strong negative correlations to successful outcome of the treatment-clinical pregnancy rate (CC: ?0.460, p?=?0.00015; CC: ?0.399, p?=?0.0012, respectively) and delivery rates (cc = ?0.396, p?=?0.00484; cc = ?0.3, p?=?0.0179, respectively).

Conclusions: Poor nations have less utilization of IVF, probably due to the limited affordability of the treatment, but reassuringly do not seem to have less success in the treatment. Further research is required to fully understand the implications of these correlations and to better design national and international fertility policies.     

A conceptual framework of adoption of an agricultural innovation

In this paper we present a conceptual framework of individual farmers' decisions on adoption of a new innovation, using the example of a new crop species. This framework overcomes the shortcomings of a number of previous studies. It represents the adoption of an innovation as a dynamic decision problem spanning at least several years. The model allows for generation of potentially valuable information from trialing the innovation. The value of such trials is due to development of skills (e.g. in agronomic management of a crop) as well as reduction in uncertainty about the innovation's long-term profitability. The framework also includes the farmer's personal perceptions, managerial abilities and risk preferences in order to properly represent the adoption decision process. The influences of socio-demographic factors within the framework are discussed.     

Choosing Brands: Fresh Produce versus Other Products

Assuming that brands contribute to quality risk reduction, prestige, and design, we derive and test hypothesis on the willingness to pay (WTP) for brands across different product categories (electronics, clothing, packaged food, and fresh produce). Using the random effect tobit model on the stated point value of WTP and the ordered probit model on the stated range of WTP, we find that WTP for brands of fresh produce is least among the four product categories controlling for relevant demographic variations. Simulations show that fresh produce has a higher optimal price premium for brands but with a much smaller market share.     

Ingredient Optimization and Children’s Liking of Popcorn Seasoned with Fish Protein Powder/Omega-3 Fish Oil

Response surface methodology (Box-Behnken design) was used to optimize the seasoning ingredients of popped popcorn. Children’s liking of seasoned popcorn was also determined by 120 school children. The results indicated that seasoning of popcorn with fish protein powder and omega-3 fish oil could produce accepted snacks that would be more nutritious than the widely consumed regular popcorn. Fortification of popcorn with 9% fish protein powder and/or 6% omega-3 fish oil did not influence the sensory attributes of the prototypes. Liking test revealed that children in the age range of 6 to 12 years liked the selected fortified products. This fortification also provided another avenue for cereal snack food diversification and might be a healthy option to boost children’s nutritional intake and to increase fish protein consumption. Such products are good choices for health-conscious consumers.     

Local country attributes and the emergence of high tech clusters

The aim of this study is to explore the effect of a country’s attributes on the decision of firms to be active globally. We first built a theoretical model, which shows that an initial difference in the business environment may dampen the desire of firms located in countries with a relatively weak business environment to seek a higher level of R&D. The decision not to pursue higher levels of R&D leads, in turn, to lower output and lower scope of activity of global firms in these countries. Moreover, firms with relatively high level of management skills will choose to migrate from a relatively weak country to one with a stronger business environment, creating a brain drain that will further impoverish the weak country.     

How do social media influencers inspire consumers' purchase decisions? The mediating role of parasocial relationships

In recent years, social media influencers (SMIs) have become part of the strategic communication of firms because the traditional form of mass media communication is losing its effectiveness. Thus, it is imperative to study the effects of communication through SMIs on marketing outcomes, such as purchase intentions. Based on the fairness dimensions, that is, information, distributive, interpersonal, and procedural, and dimensions of source credibility, that is, attractiveness, expertise, trustworthiness, and similarity, this research investigated how technology-oriented SMIs (T-SMIs) foster parasocial relationships (PSRs) with followers. Purposive sampling was employed to collect data from 506 active social media users. Data were analysed through IBM AMOS and SPSS 26. The results of the study suggested that attractiveness, expertise, trustworthiness, similarity, interpersonal, procedural, and information fairness are positively related to fostering PSR with followers. In contrast, distributive fairness does not strengthen PSR with followers; furthermore, the study findings suggested an indirect positive influence of attractiveness, expertise, trustworthiness, similarity, interpersonal, procedural, and information fairness on the purchase intentions of consumers via PSR. This study is useful for academia and industry since it fills important gaps in the literature and provides recommendations to brand managers of technology companies about selecting appropriate SMIs for the endorsement of their brands.     

Psychology, Behavioral Economics, and Public Policy

Economics has typically been the social science of choice to inform public policy and policymakers. In the current paper we contemplate the role behavioral science can play in enlightening policymakers. In particular, we provide some examples of research that has and can be used to inform policy, reflect on the kind of behavioral science that is important for policy, and approaches for convincing policy-makers to listen to behavioral scientists. We suggest that policymakers are unlikely to invest the time translating behavioral research into its policy implications, and researchers interested in influencing public policy must therefore invest substantial effort, and direct that effort differently than in standard research practices.     

Language and market inclusivity for women entrepreneurship: the case of microfinance

Inclusive markets are key to fostering female entrepreneurship, and the microfinance sector has recognized and acted on this. Existing research has studied how institutions and organizational factors facilitate the process by which microfinance and other financial intermediaries tackle gender-based financial exclusion. But while the role of cultural institutions has been recognized as important, little research has systematically integrated culture in the study of gender-based financial exclusion. We posit that language is a cultural institution that influences the extent to which financial intermediaries are successful in outreaching women and supporting female entrepreneurship. Inspired by a performativity approach, we develop a set of hypotheses that delineate how a specific feature of language, gender marking in grammar, moderates the role of institutional (state capacity) and organizational (NGO status and global ties) factors in shaping microfinance outreach to women. Using the ratio of female to male borrowers in 2361 microfinance organizations from 115 countries during the period 1995–2015, we confirm that market inclusion of women depends on organizational and institutional factors, and that gender marking in grammar influences those relationships.     

Embrace the debate: Goals,de-marketing overconsumption,and conflicting information

When faced with conflicting information, consumers often wonder what the “right” consumption level is. A highly relevant context that is often associated with such uncertainty is food consumption (e.g., of meat or dairy products), where consumers seek information to determine whether and how much to consume, and often a recommended goal from health experts is to reduce overconsumption. We apply the theory of goal settings as reflecting such information, focusing on specific goals (e.g., “eat meat twice a week”) versus general goals (“eat less meat”). Based on a series of three experiments in both online and field settings with 674 participants overall, we show that in food consumption contexts with conflicting information, general goals set by health experts are less effective than specific goals in battling overconsumption. Perceived value of information was identified as the underlying mechanism as it mediated the effect of conflicting information on reduced overconsumption. Prior work suggests conflicting information is typically disadvantageous for consumers. Our research demonstrates how consumers can benefit from communication emphasizing specific goals when information conflicts. It contributes to policymakers, health experts, and social marketers that search for effective marketing strategies to reduce overconsumption of items that may be associated with conflicting information.     

Beyond Environmental Regulations: Exploring the Potential of “Eco-Islam” in Boosting Environmental Ethics Within SMEs in Arab Markets

The recent global increase in environmental regulation does not necessarily signal improvement in firms’ ecological imprints. Like many markets, the Arab world is struggling to implement environmental compliance measures among local firms. For Arab countries, the reliance solely on formal policies to improve local firms’ ecological footprints may be risky given the evident institutional challenges to enforce environmental regulations, specially post the Arab Spring. Drawing from the literature highlighting the merits of combining formal and informal controls to ensure successful implementation of a strategy, we argue that the emphasis for regulation must be accompanied by an emphasis for developing environmental ethics of individuals, who are the expected implementers of any environmental policy. In that light, we propose that the Eco-Islam phenomenon can serve as an influential and effective foundation for building organizational cultures with stronger environmental ethics among local small and medium enterprises (SMEs). We explain the underlying maxims of Eco-Islam then conduct qualitative research among experts preaching or practicing the concept to gain better insights into the potential of leveraging it in Muslim-majority Arab countries. Finally, we conclude with insightful implications for local SMEs in the region.
