The information content of US stock market factors

Purpose The purpose of this paper is to consider the economic information content within several popular stock market factors and to the extent to which their movements are both explained by economic variables and can explain future output growth. Design/methodology/approach Using US stock portfolios from 1964 to 2019, the authors undertake three related exercises: whether a set of common factors contain independent predictive ability for stock returns, what economic and market variables explain movements in the factors and whether stock market factors have predictive power for future output growth. Findings The results show that several of the considered factors do not contain independent information for stock returns. Further, most of these factors are neither explained by economic conditions nor they provide any predictive power for future output growth. Thus, they appear to contain very little economic content. However, the results suggest that the impact of these factors is more prominent with higher macroeconomic risk (contractionary regime). Research limitations/implications The stock market factors are more likely to reflect existing market conditions and exhibit a weaker relation with economic conditions and do not act as a window on future behavior. Practical implications Fama and French three-factor model still have better explanations for stock returns and economic information more than any other models. Originality/value This paper contributes to the literature by examining whether a selection of factors provides unique information when modelling stock returns data. It also investigates what variables can predict movements in the stock market factors. Third, it examines whether the factors exhibit a link with subsequent economic output. This should establish whether the stock market factors contain useful information for stock returns and the macroeconomy or whether the significance of the factor is a result of chance. The results in this paper should advance our understanding of asset price movement and the links between the macroeconomy and financial markets and, thus, be of interest to academics, investors and policy-makers.

Prevalence of Endo, Ecto and Haemoparasites of Agama Lizards ( Agama agama ) in Maiduguri, Borno State

One hundred agama lizards ( Agama agama ) were investigated for the presence of ecto, endo and haemoparasites in Maiduguri using standard parasitological techniques. Forty four (44) of the lizards were males while the remaining fifty six (56) were females.80 were adults, while 20 were juveniles. The obtained results revealed that all the lizards were positive for one parasite or the other.Endoparasites (100%) were the most abundant as they were found in all the one hundred lizards examined. However only twenty (20) of the males were infected with haemoparasites constituting 55.6% of the haemoparasitic infection, while sixteen (16) of the females were infected with haemoparasites constituting 44.4%. No statistical significant variation in infection was encountered between the sexes (P>0.05). Similarly none of the investigated lizards was positive for ectoparasite. The distribution of the parasites based on the age of the lizards examined shows that the adults were more infected(P<0.05) with 80(80%) and 31(86.1%) infection rates for endoparasites \ and haemoparasites respectively, than the juveniles. Two (2) species of endoparasites consisting of Trichuris spp (70%) and Ascaris spp (30%) were encountered during the study, while haemoparasitic species consisted of Plasmodium (47.2%), Haemoproteus spp (30.6%) and Leucocytozoon spp (22.2%). The findings may be of epidemiological significance in the study area in view of the role of lizards as reservoirs of the identified parasites. Similarly further investigation in the study area using advance techniques such as serology and molecular techniques is needed to ascertain the status of lizards as carriers/reservoirs of diseases such as toxoplasmosis and pentastomosis which are very important in reptiles.

Identification and characterization of a prophenoloxidase‐1 (PPO1) cDNA in the cabbage butterfly Pieris rapae L.

Phenoloxidase (PO) is a melanin‐synthesizing enzyme widely distributed in animals, plants and microorganisms. It plays an important role in insect immune response. Here we report the cloning of a prophenoloxidase (PPO) cDNA from Pieris rapae, prophenoloxidase‐1 (PrPPO1). The full‐length cDNA consisted of 3338 bp, containing an open reading frame of 2049 bp encoding 682 amino acid (aa) residues. Two putative copper‐binding sites, a proteolytic activation site, three conserved hemocyanin domains and a thiolester motif, but no signal sequence, were found in the deduced aa sequence. A BLASTp search and neighbor‐joining analysis showed the deduced aa sequence had high identity to the published sequence of PPO1 from other lepidopteran insects, ranging from 71.31 to 73.15%. The results of real‐time polymerase chain reaction (PCR) showed that the highest expression of PrPPO1 was in the 4th instar larvae and the highest density of oenocytoids was observed in the 4th instar larvae also. PrPPO1 transcripts in the 4th instar larvae were significantly decreased at 6 h and 12 h with Beauveria bassiana infection; however, they were sharply increased at 72 h. PrPPO1 transcriptional level in the 5th instar larvae showed no significant changes compared with the control at 4 h with quercetin injection; however it was significantly increased at 12 h. The expression level of PrPPO1 was mainly related to the treatment time of the quercetin, but not the dose.
Influência da adição de geleia de abóbora e amido de milho nas características físicoquímicas e texturais de iogurte grego

The yogurt is thought to be a tasty product with high nutritional value. Its consumption per capita in Brazil has increased about 100% in the last 20 years. Most dairy products available in the market have added temperate climate fruits, but the agroindustry is always looking for innovation and improvement of technologies to meet the needs and requirements of consumers. Thus, aiming at the importance of developing new products with high added value, this study aimed to evaluate the influence of the addition of pumpkin jelly and cornstarch on the physicochemical and textural characteristics of Greek yogurt. The yogurts were prepared using the factorial design method 22 with 3 repetitions at the center point, resulting in a matrix with 7 experiments, with a varied concentration of starch and jelly. Subsequently, the analysis of physicochemical parameters and determination of texture pattern were examined. When analyzing the 7 formulations, it was observed that all parameters evaluated showed an increase directly proportional to the addition of pumpkin jelly and cornstarch to the product. Thus, the increase in the percentage of jelly presented the greatest interference on the response variables.
Combining ability of tropical maize germplasm in West Africa. III. Tropical maize inbreds

One hundred elite, open-pedigree tropical and subtropical inbreds of maize (Zea mays L.) that had been screened in 60 tropical trials were evaluated as inbreds and in testcrosses in Nigeria. The 24 superior inbreds among these were chosen to create two diallel sets for evaluation of grain yield and agronomic competence. Included were lines bred in Colombia, Florida, Hawaii, India, Kenya, Nigeria, South Carolina, Texas, and Thailand. The two diallels included 78 hybrids of 13 inbreds with yellow kernels and 55 hybrids of 11 inbreds with white kernels. The diallel of 13 yellow inbreds was evaluated in 11 replicated trials throughout Nigeria, and the white diallel was evaluated similarly in five environments. About 50% of the parental inbreds had dent kernels and 50% were flints. Most dent inbreds were related to Tuxpeno and Southern U. S. Dents and most flint lines were related to Caribbean germplasm. Grain yields of the 78 yellow hybrids were obtained from ten environments, whose averages ranged from 3.0 to 7.7 t/ha. The hybrids showed highly significant differences and interacted significantly with environments. General combining ability (GCA) values for the 13 elite parents, however, did not differ significantly. Every inbred served as parent of one or more outstanding hybrids. Similarly, the 55 white hybrids differed significantly in three measured environments, whose averages ranged from 2.9 to 4.5 t/ha. GCA values for the 11 elite white parents were significant (P = 0.05), and every inbred served as parent for one or more superior hybrids interactions of hybrids with environments were highly significant for the yellow diallel, but not for the white diallel, Yellow inhreds Fla2BT106 (Florida, dent) and Ki9 and Kil4 (Thailand, flint) had the highest GCA values and superior hybrids, while the four white inbreds with superior GCA values were all bred in Nigeria (TZi3, TZi8, TZi12 and TZi15) and all were flints or flinty dents, Some outstanding hybrids were flint x dent crosses, often representing the cross of Tuxpeno and Caribbean heterotic groups, but many were not. It could be argued that each of these inbreds and their close relatives represent a potential heterotic group, drawn as they were from such a wide range of tropical germplasm, and evaluated over such a wide range of environments, Breeding tropical maize inevitably focusses on resistances to diseases, insects and stresses. These data suggest that yield heterosis is no more significant as a constraint to the tropical hybrid breeder than is inbred and hybrid tolerance of biotic and abiotic stress.
A COMPARATIVE EVALUATION OF THE IMPACT AND FLEXURAL STRENGTHS OF HIGH IMPACT ACRYLIC RESIN REINFORCED WITH SILANED ZIRCONIUM DIOXIDE AND TITANIUM DIOXIDE NANOPARTICLES AND ITS HYBRID COMBINATION - AN INVITRO STUDY

resistance, the dentures tend to flex and can also fracture. With the advancement in nanoscience, nano-sized fillers were found to exhibit improved fracture resistance. Hence in this study both ZrO 2 (5%) & TiO 2 (1%) nanoparticles and its hybrid combination (2%) were used to comparatively evaluate the impact and flexural strengths of high impact acrylic resin. A total of 45 specimens were subjected to impact strength testing in an impact tester and flexural strength testing using three point bending test in a Universal testing machine respectively. The present study shows that hybrid reinforcement can be considered a better reinforcement option for enhancing the impact and flexural strengths of acrylic resin.
Assessment of phosphorus fixing capacity in contrasting soil orders in central India

Phosphate adsorption by soils is important because adsorbed P equilibrates with soil solution P, which in turn is immediate source of P. While P fixation continues to receive much attention it is more important to know the effect of soil characteristics on P fixation. Phosphorus sorption characteristics of JNKVV, Farm, Jabalpur representative agricultural soils belonging to three soil orders namely Vertisol, Inceptisol and Alfisol were investigated for adsorption behaviour of P and sorption data were fitted to Langmuir equation. The Langmuir constant i.e. adsorption maxima was highest for Vertisol (504.26 μg g-1), followed by Alfisol (480.89μg g-1) and Inceptisol (452.98μg g-1) respectively. The phosphate adsorption isotherm gave good fit adopting Langmuir (r2 = 0.98 to 0.99) for the three soils. The value of equilibrium solution P concentrations were found significantly variation under different soil orders but the adsorb P value was also found significant varied. The equilibrium solution P concentrations minimum in Alfisols 0.03 to 8.95 mgµg mL-1 and maximum in Inceptisols 0.09 to 10. 95µg mL-1, but the adsorb P value was minimum in Inceptisols 19.01 to 290. 41µg mL-1 and maximum were recorded in Alfisols 19.64 to 310. 47µg mL-1. In Vertisols the value of equilibrium solution P concentrations were found in the range of 0.13 to 10. 08µg mL-1 and adsorb P values were 18.65 to 299. 13µg mL-1. The range of P buffering capacity was 60.07 to 70.89 L kg-1. The highest value of MPBC was found in Alfisols with the mean value 68.89L kg-1and the lowest of MPBC value was found in the Inceptisols with the mean value was 63.72L kg-1. Correlation of Adsorption parameters of Langmuir and were worked out taking all soil types together with pH, EC, organic carbon, clay, CEC and CaCO3. For the Lamgmuir equation, value of ‘r’ indicated that P adsorption maxima (b) was significantly and positively correlated with pH (r=0.993**), clay (0.916**) EC (r= 0.734*).
Impact of word of mouth via social media on consumer intention to purchase cruise travel products

ABSTRACT Social media has changed how tourists source and assess information about tourist products and destinations. Tourists can now easily share their travel experiences through text-based posts, photographs, and real-time videos on social media. Such word of mouth (WOM) allows tourists to focus on and develop an interest in diverse tourism experiences and efficiently interact with other travelers as reliable information sources. However, studies on the cruise industry remains scarce in this issue. Thus, this study examines the impact of travel information sourced from social media on consumers’ purchase intentions with WOM (WOM praise and WOM activities) as a mediating factor. The analysis employs a value-based adoption model derived from prospect theory and mental accounting theory from the perspective of benefit maximization (information reliability and enjoyment). Empirical data are collected (n = 305) using a survey. Structural equation modeling reveals that social media users’ WOM significantly influences consumers’ purchase intentions. That is, WOM increases the benefits of sourcing information on cruise travels from social media. Further, experience sharing through WOM significantly impacts consumers’ decision making. The study concludes with theoretical and practical implications.

Perspectives on wastewater treatment wetlands and waterbird conservation

Summary 1. With the global loss of natural wetlands, waterbirds have become increasingly dependent on alternative and artificial habitats, but the use of such wetlands by waterbirds is typically opportunistic and little consideration has been given to the potential implications for water treatment or waterbird conservation objectives. 2. Wastewater treatment wetlands are currently of critical importance for certain waterbird species in some parts of the world, and we illustrate this with an example from south-eastern Australia. Furthermore, we argue that their significance is likely to increase as they offer the most realistic means of treating wastewater in developing countries, where the demand for improved sanitation to lift people out of poverty is intense. 3. There is little scientific evidence to guide the construction of wastewater treatment wetlands with waterbird conservation in mind. 4. The use of wastewater by waterbirds poses health risks for both birds and humans and these risks must be better understood. 5. Synthesis and applications. Wastewater treatment wetlands are not a substitute for natural wetlands and reliance upon them should not compromise wetland conservation efforts. Nonetheless, they are a potentially valuable resource for waterbirds, and research should be directed towards deepening our understanding of their global distribution; food-web dynamics; methods of deterring or excluding birds when bird or human health may be compromised; the effects of wastewater contaminants and pathogens on birds; and the role of waterbirds in human disease transmission.
Teaching ‘out of field’ in STEM subjects in Australia: Evidence from PISA 2015

Science, technology, engineering and mathematics (STEM) education is a critical part of a modern education system. Motivating students to learn STEM subjects is however a challenge. Teachers have a critical role in motivating students but to do this effectively they need to have appropriate subject matter knowledge. Data from PISA 2015 show a substantial proportion of teachers in Australian schools are teaching STEM subjects ‘out-of-field’, which is that they do not have the qualifications to teach these subjects. This paper examines the effects of individual teacher characteristics and school context on of out-of-field teaching in STEM subjects. In particular, it examines the role of school autonomy and staff shortage in this. The results show these two variables have a strong association with out-of-field teaching, however, other factors either mediate or confound their effects. A full understanding of the results requires knowing the role of school funding and school budgets in out-of-field teaching. While we do not have direct measures of these in the data, we can infer their likely roles through the effects of other factors, such as school sector and education level of parents of students in the school, in the model.
How novice and experienced entrepreneurs name new ventures

ABSTRACT We examine the role of entrepreneurial experience in shaping a key decision that every entrepreneur has to make: naming their new venture. Using a qualitative approach, we compare and contrast serial and novice entrepreneurs as they name the same company. We find several naming practices and show that novice and serial entrepreneurs use distinct naming strategies reflecting appeals to cognitive and emotional resonance. Our findings contribute to theory on firm names with a much-needed account of naming practices and provide insights for research on legitimation by showing that differences in entrepreneurial experience are consequential for venture naming decisions.
Bank Monitoring and Financial Reporting Quality: The Case of Accounts Receivable–Based Loans*

Using novel receivable-based-loan data, we study the effect of aging-report loan covenants on borrowers’ accounts receivable reporting quality. Our purpose is to highlight a channel that lenders use to obtain private information and to understand whether lenders’ information acquisition affects the financial reporting quality of borrowers. Compared to receivable-based borrowers without aging-report requirements (control firms), borrowers with such requirements (test firms) increase their receivable reporting quality significantly after loan initiations. The shift in reporting quality is more pronounced when borrowers have weak bargaining power. Our results lend support to the argument that lender information access affects borrowers’ reporting quality.
The growth, pilodyn penetration, and wood properties of 12 Neolamarckia cadamba provenances at 42 months old

Abstract. Anna N, Supriyanto, Karlinasari L, Sudrajat DJ, Siregar IZ. 2020. The growth, pilodyn penetration, and wood properties of 12 Neolamarckia cadamba provenances at 42 months old. Biodiversitas 21: 1091-1100. Jabon (Neolamarckia cadamba (Roxb) Bosser) is a potential tree species for the development of plantation forests and community forests to supply timber demands. Information on the growth characteristics and wood properties of N. cadamba is important for the present and future development, yet. Those data is not available. This study aimed to assess the variations on growth (height, diameter), pilodyn (Pilodyn®) penetration, and physical properties of wood from core sample; and characterize the wood properties of 12 N. cadamba provenances at Parung Panjang, Bogor. The assessment of growth characteristics, pilodyn penetration, and physical properties of wood from core sample was carried out through census (1030 trees) on all provenance (using non-destructive method). The wood properties analysis was carried out using destructive method to one sample for each of the 12 N. cadamba provenances. Growth characteristics observed were the height (numerical scale pole), diameter (calipers), and pilodyn penetration. Meanwhile, the wood properties consisted of wood density, specific gravity, moisture content, fiber length (light microscope), MFA (x-ray diffraction), MOE, and MOR. The results showed that the correlation between the height and moisture content with pilodyn penetration was weak and positive, while the correlation between diameter, wood density, and specific gravity was weak and negative. The result of non-destructive test showed that Gowa provenance is superior. The results of destructive tests to investigate the wood properties of the twelve provenances showed that Batu Licin provenance is superior in terms of specific gravity and MOE, while Gowa provenance is superior in terms of MOR and fiber length. The results of the wood properties (i.e. density, specific gravity, moisture content, MOE, MOR, MFA, and fiber length) of the 12 N. cadamba provenances showed that the woods can be potentially used as non-structural materials only.
