The relationship between the levels of α-tocopherol and carotenoids in the maternal feed, yolk and neonatal tissues: comparison between the chicken, turkey, duck and goose

The relationship between the levels of the lipid-soluble antioxidants, a-tocopherol and carotenoids, in the parental diet, the yolk and the neonatal tissues was investigated for four avian species of commercial importance. The chicken displayed a much greater efficiency in incorporating a-tocopherol from the parental diet into the yolk in comparison with the turkey, duck and goose. Thus, in spite of similar concentrations in the respective diets, the resultant con- centration of a-tocopherol in the yolk of the chicken egg was four to -ve times greater than observed for the other three species. A similar but less dramatic picture was observed for carotenoids: identical dietary provision of carotenoids in the maternal feeds resulted in the chicken eggs displaying between 1E4 and 1E9 times the concentration in the yolk than was observed for the other three species. These di†erences between the species regarding the levels of a-tocopherol and carotenoids in the yolk were closely reNected in the subsequent concentrations of these components in the livers of the hatchlings. Thus, the concentrations of a-tocopherol and carotenoids in the liver of the day-old chicken were respectively about three and two times greater than in the livers of the other three species. Although the water-soluble antioxidant, ascorbic acid, is synthesised by the embryo as opposed to provision via the maternal diet and the yolk, the concen- tration of this component in the brain of the day-old chicken was approximately 50% greater than in the brains of the other three species. Thus, it is possible that the antioxidant capacity of the developing turkey, duck and goose may be com- promised under conditions of commercial production. All four species displayed a rapid depletion of a-tocopherol and carotenoids from the livers during the -rst 9 days after hatching. 1998 SCI. (
Social Media Capital: Conceptualizing the Nature, Determinants, and Outcomes of Social Media-Based Organizational Resources

The near-universal organizational participation in social media is predicated on the belief there are some tangible or intangible new resources to be had through tweeting, pinning, posting, friending, and sharing. We argue the linchpin of any payoff from engagement in social media is a special form of social capital we refer to as 'social media capital', and offer a conceptual framework for understanding its nature, determinants, and consequences. This paper contributes to existing accounting literature by elaborating a new type of organizational resource and then synthesizing and extending research on the processes through which organizations can translate social media efforts into meaningful organizational outcomes. Understanding this causal chain is critical not only for measuring the return on investment from social media use but also for developing accounting information systems that are both adaptable to social resources and better able to exploit the data analytic and forecasting capabilities of real-time Big Data.
Selling Signals

This paper studies a signaling model in which a strategic player can manipulate the signaling cost. A seller chooses a price schedule for a good, and a buyer with a hidden type chooses how much to purchase as a signal to receivers. When receivers observe the price schedule, the seller charges monopoly prices, and the buyer purchases less than the first-best. In contrast, when receivers do not observe the price schedule, the demand for signals is more elastic. We propose a new refinement, the Quasi-Divinity, to refine the equilibria. In equilibrium, the seller charges lower prices, and the buyer purchases more than when receivers observe the price schedule; the highest buyer types purchase more than the first-best. The model suggests that price transparency benefits the seller but harms the buyer. The model can be applied to schools choosing tuition, retailers selling luxury goods and media companies selling advertisements.
Cluster Analysis Using Big Data Visualization

Big Data analytics tries to explore hidden information from huge amount of data in order to make informed decisions. Trying to decipher the true meaning from the streams of data generated is a cumbersome task. Visualization techniques help in gaining a complete view of the trends and patterns of the data. So, Big Data visualization is as integral part of Big Data analytics solutions as it is easier to comprehend the data that has such a large volume and high velocity. In this paper, we address Big Data visualization with the help of affinity propagation technique that helps us to make informed decisions in the domain of stock market.
Natural biological control of green scale (Hemiptera: Coccidae): a field life-table study

Understanding how the biotic and abiotic factors influence pest-population dynamics is important to implement sound pest management strategies in biological control and integrated pest management (IPM) programmes. Coccus viridis (Green) is an important indirect pest of coffee plants, but very little has been done to understand the factors that contribute most for its biological control in the field. In the present study, we examined the critical life stage and the key factors associated with the mortality of C. viridis in coffee plantations in Brazil by conducting field-based life table studies. Predators, parasitoids, fungi, infested leaf abscission and rainfall were collectively responsible for a total C. viridis mortality of 96.08%. Predation by coccinellids was the key factor governing the mortality of C. viridis. The parasitism of early instars by parasitoids was the second most important factor contributing to C. viridis mortality. Unlike the parasitoids, the fungus Lecanicillium lecanii caused mortality of scales in more advanced life stages. The abscission of infested leaves from the trees, and rainfall also contributed to the mortality of C. viridis. The nymph stage was considered the critical stage for mortality of C. viridis in the field. The results suggest that predators (Coccinellidae) are the most important factors controlling C. viridis, and thus should be the target of conservation measures in coffee plantations infested with this pest.
NEWS SHOCKS AND THE EFFECTS OF MONETARY POLICY

Traditionally identified monetary shocks in a structural vector autoregression (SVAR) model typically result in long-lasting effects on output and total factor productivity (TFP). In this paper, I argue that the typical monetary shock has been confounded with the news shock about future technology. I propose and implement a novel SVAR approach that effectively “cleans” the technology component from the traditional Cholesky monetary shock. With the new identification, I find that a monetary shock exerts smaller and less persistent effects on output and the level of measured TFP than a traditionally identified monetary shock. Finally, I show that the SVAR impulse responses can be replicated by augmenting the standard New Keynesian model with a time-varying inflation target and a non-Ricardian fiscal policy regime.
Managing the Impact of Fitting-Room Traffic on Retail Sales: Using Labor to Reduce Phantom Stockouts

Problem definition: Brick-and-Mortar (B&amp;M) retailers must enhance the customer in-store experience to better compete with online retailers. Fitting rooms in B&amp;M stores play a critical role in the customer experience as a venue to experience products and examine alternatives. High traffic in fitting rooms, however, obstructs the customer's ability to choose a product. In this paper, we (1) examine the impact of fitting-room traffic on store performance using archival data, (2) identify phantom stockouts as a plausible mechanism for this impact, and (3) provide a potential solution and quantify the magnitude of its impact using two field experiments. <br><br>Academic/Practical Relevance: The consumer purchase decision process framework has been widely used in disciplines such as Marketing and Information Systems. We consider the impact of high traffic in fitting rooms on customer’s purchase decision process. We show that high traffic in fitting rooms affects store sales negatively as it can obstruct customers’ ability to perform information search, evaluation of alternatives, or both. <br><br>Methodology: We use archival data analysis, a field study, and a field experiment to demonstrate our findings. <br><br>Results: We demonstrate an inverted-U relationship between fitting-room traffic and sales using archival data analysis. Our field study reveals that high traffic in fitting rooms exacerbates phantom stockouts, which could contribute to the decline in sales. Finally, through field experiments at two retailers, we show that a timely backend recovery operation through a dedicated fitting-room associate reduces phantom stockouts and increases sales by 22.4%-22.7%. <br><br>Managerial Implications: First, contrary to conventional wisdom that traffic drives sales, we identify that fitting-room traffic beyond a certain point can hurt store sales. Second, we find a large magnitude of phantom stockouts in fitting rooms. Finally, we show that dedicated fitting room labor can significantly boost store sales by alleviating phantom stockouts. Our proposed solution was adopted by both retail organizations that we worked with. <br>
Financial Evaluation in Project Appraisal: A Value Added Approach

The purpose of this article is to outline various cost-benefit financial evaluation methods for use in project appraisal with regard to private capital investment projects with the inclusion of uncertainty and risk allowance factors in determining the net expected financial return from a given capital investment project. Two factor allowances for uncertainty have been used: the first deals with uncertain future benefit and cost streams and utilizes linear approximations for non-linear continuous functions of random variables using the inverse-transformation technique and the invariance method of maximum likelihood estimation, while the second is a von-Neumann covariance risk factor controlling for the project’s external environment. Results yield two general indicators of important use in project evaluation: value and net value-added, the former being an indicator of project feasibility while the latter an indicator for investment profitability.
Effect of different processing methods on certain antinutritional factors and protein digestibility in green and white faba bean (Vicia faba L.)

Effects of several physical treatments (soaking, dehulling, ordinary cooking, microwave cooking, and autoclaving) on the level of antinutrtional factors and in vitro protein digestibility (IVPD) of green and white faba beans were investigated. The raw green and white faba bean seeds were found to contain phytic acid (PA), tannins, trypsin inhibitor activity (TIA), and lectin activity, but α-amylase inhibitor was absent. Dehulling significantly increased the levels of PA, TIA, decreased the level of tannins, but lectin activity was not changed. Cooking methods differently affected the levels of the antinutrtional factors. Thus, PA increased but tannins were not changed; on the other hand, TI and lectin activities were inactivated; ordinary cooking and autoclaving were the most effective in both seeds. For combination effect, soaking following cooking treatments significantly decreased PA, tannins, and lectin activity but increased TIA in both seeds. Moreover, dehulling following soaking and cooking methods resulted in a significant increase of PA and TIA. In vitro protein digestibility of raw green and white faba bean seeds were 72.65 and 73.28%, respectively, and it was improved by all processing methods; soaking-dehulling after autoclaving was the most effective in both seeds. Although some treatments increased the level of antinutrtional factors, they improved IVPD. Therefore, the studied antinutrients are not the only responsible factor for lowering IVPD.

The COVID – 19 Crisis Brings Spring Season for Translucent Activity. Does It Result Exogenous Uncertainty for the Entrepreneurs and Bound-Less Commodity Pricing!

In the beginning of 2020, uncertainty has covered up the global economy due to the Coronavirus disease (COVID – 19) pandemic. This emerging issue is also tailing other indirect social problems like food crisis, plummeting share prices (Ayittey et al., 2020; Ramelli, S., & Wagner, A. F., 2020), export and import delays. The uncertainty, because of the SARS-CoV has begun from Wuhan, China in the last quarter of 2019 and now been spreading out all over the world by the first quarter of 2020 (Ayittey, Foster Kofi, et al., 2020). The confirmed positive cases are counted near to three hundred thousand by March 22, 2020 (World Health Organization, March 22, 2020) and constantly increasing day by day. Unofficially, the number of people infected by and the fatality rate due to this virus has been dramatically rising up in the developing countries like Bangladesh, Iran, India and so on. This sudden global pandemic caused production halts in many manufacturing companies in the USA. Not only in the U.S.A. but also in the Bangladesh, the Coronavirus crisis has interrupted the upward economic flow of entrepreneurs especially who have new or break-even reaching startups. In Bangladesh, we collected survey opinion from 693 entrepreneurs (local producers and retailers) and 128 representatives of pharmaceuticals companies regarding the ongoing business threats due to the COVID – 19 pandemic. Our study reflects that the price of agricultural items and pharmaceutical products are increased by local syndicators at present. As a result, the exogenous uncertainty is increasing among entrepreneurs and raising the retail price of commodities in the pharmaceuticals industry as well as agro-industry.
The Relationship between Insurance Growth and Economic Development: 80 Empirical Papers for a Review of the Literature

The objective is to examine the determinants of the relationship between insurance growth and economic development. This paper contributes to this body of research by providing an extensive literature review of empirical studies that have looked at both sides of the relationship, i.e. the demand side (economic growth is an explanatory variable among other factors that affect the demand) and the development side (insurance is a determinant of growth).
Microfoundations of Resource Search

Where do new resources come from? We build on the premise that environments feature vast reservoirs of latent resources, uses and resource combinations. However, identifying this value can be costly and difficult. In this paper we consider the thought experiment of an endowment-less firm and how it might search for and develop latent resources. We build on perception science and evolutionary biology to highlight how the notion of “searching-for” foreshortens costly search processes. Contrarian beliefs offer a mechanism for generatively seeding search and bootstrapping resources and heterogeneity. Beliefs partially solve the factor markets problem; though their realization is dependent on developing firm-specific theories of value and targeted experimentation. Our approach also addresses how firms might actively harness the adjacent possible. We conclude with a discussion of how our arguments relate to fundamental questions in the field of strategy and the resource-based view.
Efficient production of novel floral traits in torenia by collective transformation with chimeric repressors of Arabidopsis transcription factors

Molecular breeding with genetic modification enables the production of novel floral traits in floricultural plants that could not be obtained by traditional breeding. To facilitate novel flower production, we collectively introduced 2 sets of 42 and 50 chimeric repressors of Arabidopsis transcription factors into Agrobacterium and then used these to co-transform torenia (Torenia fournieri). We generated 750 transgenic torenias, and identification of the transgenes revealed that more than 80% of the transgenic torenias had a single transgene. A total of 264 plants showed phenotypic modification, and 91.2% displayed modified flower colors and/or shapes, such as altered color patterns, curled petal margins, and wavy petals. These results indicated that the collective transformation system can be applied to molecular breeding of flowers. Detailed analysis of the phenotypes revealed that PETAL LOSS could control blotch sizes and that modification of cell shape could change the texture of petals. We found that the chimeric repressors of functionally unknown transcription factors also induced novel floral traits, and therefore, the transgenic torenias provide an understanding of the functions of transcription factors that could not be revealed by previous studies in Arabidopsis.
Has the Inflation Process Changed?

On 18-19 June 2004, the BIS held a conference on "Understanding Low Inflation and Deflation". This event brought together central bankers, academics and market practitioners to exchange views on this issue (see the conference programme in this document). This paper was presented at the workshop. The views expressed are those of the author(s) and not those of the BIS.
Employment Effects of Job Counseling for Disability Insurance Recipients

Many countries implement policies to promote labor market inclusion of disability support recipients. It is unclear whether such measures work. We exploit a quasi-experimental setting in Australia where compulsory job counseling was introduced in 2012 affecting only those social security disability insurance (DI) recipients below age 35. Using longitudinal administrative data on all DI recipients and applying a difference-in difference estimator, we find that the policy was largely ineffective and neither improved employment nor earnings.
Analysts' Forecast Error: A Robust Prediction Model and its Short Term Trading Profitability

We examine the profitability of implementing a short term trading strategy based on predicting the error in analysts' earnings per share forecasts using publicly available information. Since large earnings surprises may lead to extreme values in the forecast error series that disrupt their smooth autoregressive dynamics, we propose to use robust fixed effect panel estimation methods as an alternative to panel least squares or the pooled least absolute deviations estimator. For the I/B/E/S data from 1998 to 2010, we show that the strategy of taking a long (short) position in stocks with the most pessimistic (optimistic) consensus forecast and closing the position on the first post announcement day has an annual gross abnormal return of 16.56%, after correcting for market risk, size, book-to-market and price momentum effects. A key insight is that the profitability of the trading strategy stems from using robust forecasting methods.
Profenofos-induced effect on esterase activity and protein content in liver, kidney, brain, blood, and muscles in Indian major carp

The objective of this study was to determine the biochemical alterations induced by acute exposure to profenofos (OP) on esterase activity in liver, kidney, brain, blood, and muscles of Catla catla, Labeo rohita, and Cirrhinus mrigala fingerlings. Pesticides were applied to fingerlings that had been grown under optimized standard conditions maintained in a static bioassay system. The fingerlings of Catla catla, Labeo rohita, and Cirrhinus mrigala were exposed to three sub-lethal concentrations of profenofos 0.038, 0.019, 0.012; 0.06, 0.03, 0.02; and 0.041, 0.02, 0.013, respectively, for 60 days. The activity of cholinesterases (acetylcholinesterase and butyrylcholinesterase) was significantly inhibited at concentrations of profenofos. Exposure to profenofos affected the functions of these organs, including metabolism and neurotransmission to varying extent at different exposure concentrations. Data indicated that profenofos produced greater inhibition of hepatic cholinesterases compared to other tissues.
Who Does (Not) Benefit from Entrepreneurship Programs?

We evaluate a technology entrepreneurship training program by comparing career decisions among applicants accepted into the program with unaccepted applicants who are program finalists. We find that program participation is associated with an increased likelihood of subsequent entrepreneurship but that this is not uniform across participants; the estimated relationship between program participation and subsequent entrepreneurial activity is disproportionately lower for applicants with ex-ante resources and capabilities in entrepreneurship, measured by prior entrepreneurship experience. Moreover, we only observe this reduced impact of the program on subsequent entrepreneurial activity for participants that have prior experience in founding a technology company as opposed to other forms of entrepreneurial activity. This suggests the program is more effective for individuals that have otherwise limited access to technology entrepreneurship opportunities.
