Disentangling the Pros and Cons of Flexible Work Arrangements: Curvilinear Effects on Individual and Organizational Outcomes

The use of flexible work arrangements (e.g., remote, hybrid) has spread during the pandemic and cumulative studies provide mixed findings on the positive vs. negative consequences of these working methods for employees and organizations. The present study examined the potentially curvilinear effects of employees’ attitude towards flexible work options (i.e., flexible work orientation; FWO) on individual- (i.e., performance, job satisfaction, stress, work-to-family conflict, family-to-work conflict) and organization-related outcomes (i.e., organizational social support, organizational justice, affective organizational commitment). Anonymous survey data were collected in 2021 from 1061 in-person and flexible workers nested within 100 Italian organizations. Measurement invariance across the two subsamples was supported and subsequent structural model analyses suggested a differential pattern of results for in-person and flexible workers. Results indicated a curvilinear U-shaped relationship between FWO and organizational support, justice, commitment and job satisfaction for the in-person subsample as compared to a positive linear relationship for flexible workers. Moreover, in both samples of flexible and in-presence workers, FWO exerted a positive linear effect on performance and a mainly negative linear effect on stress, WFC and FWC. Overall, flexible workers displayed linear relationships among all the study variables, whereas in-person workers showed the curvilinear effects of FWO on support, justice, commitment and satisfaction, all of which increased at high levels of employees’ positive attitude towards FWO. Results are discussed in light of the globally elevated rates of flexible work arrangements and mixed findings on their implementation.

Performance Evaluation of Directional Porous Oil Storage Medium Fabricated by PTFE and Naphthalene

Porous oil storage media is the core of self-lubricating rolling functional components. The internal pore directivity of porous oil storage media is different，and it reduces the utilization rate of lubricating oil. In this paper, a new fabrication method of porous oil storage media with directional pores is carried out, and the properties of the porous media, such as hardness, density, porosity, oil storage rate and oil retention rate are evaluated. The experimental results show that the fabrication pressure has a linear positive effect relationship with the hardness of the porous media, and has no significant effect on the density, porosity, oil storage rate and oil retention rate. The mass fraction of pore former has a linear negative effect relationship with the hardness and density of the porous media, and a linear positive effect relationship with the porosity the greater the mass fraction of pore former, the greater the initial oil seepage rate of oil rejection. The internal pores of the porous media have a fibrous structure of the karst cave type, and the internal pores are interconnected and have good orientation. This study aims to provide a lubricating theoretical reference for the fabrication of porous oil storage media.

Do commitment and asset specificity serve as the double-edged sword to assist co-production in enhancing value co-creation? A dyadic approach in Taiwan

PurposeValue, also known as co-creation, is recognized as the outcome of collaborative efforts between both parties. However, knowledge is currently limited regarding the motivations and mechanisms driving customers to engage in co-production and value co-creation. Therefore, the current study aims to investigate co-production in enhancing value co-creation. Previous research has predominantly explored the linear effects of commitment and asset specificity on co-production. To expand on this foundation, our study goes a step further by including the potential quadratic effects of commitment and asset specificity on co-production. Although moderate levels of commitment and asset specificity may enhance co-production, higher levels are implied to possibly impede it. Considering that co-production requires collaboration between customers and service employees, this study includes the characteristics of service employees, such as self-monitoring and self-efficacy, identifying their moderating roles in aiding active co-production and ultimately enhancing the value co-creation.Design/methodology/approachWe employed linear, nonlinear and hierarchical moderated regression analysis to test our hypotheses.FindingsOur findings provide evidence for the positive linear effects and negative quadratic effects between commitment, asset specificity and co-production. The inverted-U relationships suggest an existing optimal commitment and asset specificity that maximize co-production. Results also suggest that co-production influences value co-creation and self-efficacy and self-monitoring positively moderates the relationship between co-production and value co-creation.Originality/valueBy applying the core provisions of S-D logic, this study contributes to marketing literature by analyzing the dyadic process of co-production. Dyadic data collection from both customers and service employees provides a comprehensive understanding of the co-production process, allowing academics to recognize service employees’ self-efficacy and self-monitoring that contribute to effective co-production and value co-creation in service processes.

Productivity and economic performance of Nellore young bulls fed diets with increasing fiber content.

Adequate neutral detergent insoluble fiber (NDF) content in the total diet can improve intake efficiency, prevent rumen disorders, and enhance the health and performance of feedlot-finished beef cattle. We hypothesized that an increase in dietary fiber levels would decrease the productive performance but increase the economic performance of young bulls in confinement. Thus, it was aimed to evaluate the effect of increasing fiber levels on feed intake, wastage, and productive and economic performance of Nellore young bulls finished in confinement. We used 20 Nellore cattle, non-castrated males, 30 months old, and average body weight (BW) of 416.35 ± 2.2kg distributed in a completely randomized design, kept in individual stalls. Animals were divided into four treatments consisting of four levels of neutral detergent insoluble fiber (NDF) (25%, 30%, 35%, and 40% NDF) in total DM. Nutrient intake, feed conversion, feed waste, body weight (BW) at slaughter, total weight gain (TWG), average daily gain (ADG), hot carcass weight (HCW), and carcass yield (CR) were evaluated. In addition, economic parameters (revenue, food expenses, and gross margin) were calculated and compared. The dry matter (DMI), organic matter (OMI), crude protein (CPI), and ether extract (EEI) intakes showed quadratic behavior. The DMI maximum estimated was 28.5% NDF in the diet. The NDF and ADF intakes showed a positive linear effect and the starch intake had a negative linear effect. There was a significant positive linear effect (P < 0.05) for the variables total mixed ration (TMR) offered and daily and total RTM intake. Minimum RTM wastage was estimated with a diet containing 30% NDF. The maximum points for BW at slaughter, HCW, and ADG were 29.9%; 29.6%, and 25% NDF, respectively. The costs of concentrate and silage showed a positive linear behavior, as did the ADG costs and the carcass equivalent cost (P < 0.05). The maximum point of the revenue estimate (US$/animal) was 29.9% of NDF, 26.1% of NDF for the total expenditure on food (US$/animal), and 32.5% of NDF for the gross margin (U$/animal). In conclusion, the animals fed a 30% NDF diet showed the best performance and economics, in addition to less food waste. We recommend 25 to 32.5% of NDF in the diet to obtain maximum productive and economic performance when finishing Nellore young bulls in confinement.

Manufacturing and the real exchange rate: natural resource rents matter when measuring misalignments

ABSTRACT We analyse the relationship between the share of manufacturing in GDP and real exchange rate misalignments based on the purchasing power parity criterion (PPP) and a sample of 102 developing and transition economies (2003–2019). In a departure from usual practice, we subtract natural resource rents from GDP in order to correct misalignments for the productivity bias. A dynamic threshold panel model is used and we separate out the impact of undervaluation and overvaluation components in the same regression. Overvaluation has a negative linear effect, while undervaluation stimulates the manufacturing sector in a non-linear way. Above an 18% threshold, the marginal effect of undervaluation diminishes.

How Much Government Debt Is Now Acceptable for Russia?

The period of near-zero interest rates is over, and the recent noticeable growth in the debt burden, as well as in the cost of interest payments to service that debt, has made it more challenging for national and global financial regulators to strike a balance between keeping budgetary parameters stable and spurring economic development. This article proposes a “safe” threshold for the debt burden such that the ac-cumulated debt would not diminish prospects for growth and degrade fiscal sustainability. A significant negative linear effect of government debt on GDP growth rates from 1980 to 2021 has been observed for a total sample of 57 countries. According to the Hansen test, there are relatively safe thresholds for high- and middle-income countries at 56% and 24% of GDP, respectively. An assessment of the impact of government debt on the dynamics of interest expense indicates that there is a stable positive relationship between them. The conclusion drawn is that the thresholds beyond which an acceleration in the growth of interest payments would produce an increase in the debt burden stand at 51% and 29% of GDP, respectively, for the same groups of countries. However, the current conditions of unprecedented sanctions that restrict access to foreign borrowing together with a double-digit key interest rate were not taken into account for calculations based on the retrospective data. When those factors are included, the authors’ projections indicate that Russia’s safe level of debt should not exceed 20% of GDP.

Financial Crisis, Confidence in Financial Markets and Participation in Private Pension Plans in Germany

The financial crisis of 2008/2009 has not only left its mark on the value of retirement savings, but also on savings and investment behaviour. It has led to a loss of confidence in financial markets and its main protagonists. However, trust is a key mechanism for savings and investment decisions. We illustrate the loss of trust by looking at the number of pension plans purchased in the years following the financial crisis. The paper is based on data of the study on ‘Life courses and old-age provisions’ (LeA, Lebensverläufe und Altersvorsorge). The data was gathered in 2016 and provides information on the life histories of people living in Germany who were born between 1957 and 1976, as well as on pension entitlements in all three pillars of the German pension system. The analysis concentrates on so-called Riester pension plans, the most dynamic private pension scheme in Germany. We estimate a panel fixed-effects logit model to examine whether the financial crisis had an impact on the participation in Riester pension plans. Results show that instead of a shock effect relating to the crisis years, we see a negative linear effect following the crisis.

Bentonite as an arsenic and lead adsorbent in the bovine digestive tract: an in vitro study

Objective. To determine the recommended dose of bentonite as a chelator of arsenic (As) and lead (Pb) in the rumen, abomasal and duodenal environment by means of an in vitro system, considering the variables of ruminal fermentation and the adsorbent effect of As and Pb. Materials and Methods. Vials were prepared with 50 mL of anaerobic medium and 0.5 g of alfalfa as substrate. The culture media were added with 1.01 and 1.95 ppm of As and Pb, respectively. The treatments consisted of different levels of bentonite (B) added to the medium, B-0%, B-1.5%, B-3.0% and B-4.5%. The media were incubated for 24 h, and pH, volatile fatty acid (VFA) and N-NH3 production, in vitro DM digestibility (IVDMD) and chelating effect of bentonite were measured, simulating rumen, abomasum and duodenum conditions. A completely randomised design and orthogonal contrasts were used. Results. Bentonite did not modify the pH (p &gt; 0.05) and the molar proportion of VFAs, but the total VFA concentration presented a negative linear effect with increasing bentonite levels. Likewise, the N-NH3 level decreased (p &lt; 0.05) with increasing inclusion levels of bentonite. The IVDMD was reduced with B-3% and B-4.5% (52.36b and 49.74b%) in comparison to B-0% and B-1.5% (62.30a and 61.98a%). Treatments B-1.5% and B-4.5% improved (p &lt; 0.05) As and Pb adsorption in the rumen, abomasal and duodenal environments. Conclusions. The recommended level of bentonite as chelator of As and Pb is 1.5%; doses of 4.5% affect IVDMD and, consequently, animal productivity.

A theory for context-dependent effects of mammalian trampling on ecosystem nitrogen cycling.

Large mammalian herbivores substantially impact ecosystem functioning. As their populations are dramatically altered globally, disentangling their consumptive and non-consumptive effects is critical to advance mechanistic understanding and improve prediction of effects over ecosystem and Earth-system spatial extents. Mathematical models have played an important role in clarifying potential mechanisms of herbivore zoogeochemistry, based mostly on their consumptive effects as primary consumers and recyclers of organic and inorganic matter via defecation and urination. Trampling is a ubiquitous effect among walking vertebrates, but the consequences and potential mechanisms of trampling in diverse environments remain poorly understood. We derive a novel mathematical model of large mammalian herbivore effects on ecosystem nitrogen cycling, focusing on how trampling and environmental context impact soil processes. We model herbivore trampling with a linear positive or negative additive effect on soil-mediated nitrogen cycling processes. Combining analytical and numerical analyses, we find trampling by large mammalian herbivores is likely to decrease nitrogen mineralisation rate across diverse environments, such as temperate grassland and boreal forest. These effects are mediated by multiple potential mechanisms, including trampling-induced changes to detritivore biomass and functioning (e.g. rate of organic matter consumption). We also uncover scenarios where trampling can increase nitrogen mineralisation rate, contingent on the environment-specific relative sensitivity of detritivore mineral-nitrogen release and detritivore mortality, to trampling. In contrast to some consumptive mechanisms, our results suggest the pace of soil nitrogen cycling prior to trampling has little influence over the direction of the trampling net effect on nitrogen mineralisation, but that net effects may be greater in slow-cycling systems (e.g. boreal forests) than in fast-cycling systems (e.g. grasslands). Our model clarifies the potential consequences of previously overlooked mechanisms of zoogeochemistry that are common to all terrestrial biomes. Our results provide empirically testable predictions to guide future progress in empirical and theoretical studies of herbivore effects in diverse environmental contexts. Resolving ecological contingencies around animal consumptive and non-consumptive effects will improve whole-ecosystem management efforts such as restoration and rewilding.

Multi-Dimensional Impacts of Climate Change on China’s Food Security during 2002–2021

Climate change poses a significant threat to food security, necessitating a thorough examination across multiple dimensions. Establishing appropriate food security evaluation indicators that align with the evolving concept of food security is imperative. This study enhances food security evaluation by designing a multi-dimensional framework and analyzing the impact of climate variations across various regions from 2002 to 2021. By constructing a food security evaluation system that encompasses the production quantity and quality, sustainability, affordability, and resources, and utilizing the entropy method for accurate weighting, the impacts of climate variations on food security are accessed using a climate–economic model. The food security structure in China largely mirrors the regional division of grain, with the production quantity being the primary contributor. Overall, China’s food security has generally demonstrated improvements across various dimensions, with the exception of production quality. Regarding climate change, which encompasses variations in mean states and climate extremes, the panel regression analysis uncovers a negative linear relationship between food security and temperature. Conversely, the impact of precipitation on food security is non-linear, manifesting as inverse U-shaped patterns. In regions with balanced production and consumption, both accumulated temperatures and extreme high temperatures have a negative linear effect on food security. On the other hand, both accumulated and extreme precipitation exhibit inverse U-shaped non-linear impacts on food security in the main production and main consumption regions. These findings highlight the intricate interplay between climate change, regional disparities, and food security in China, emphasizing the need to consider multi-dimensional factors and regional variations in addressing food security challenges. These insights are invaluable for policymaking and planning aimed at enhancing food security in China.

Effect of supplementing zilpaterol hydrochloride during different periods on energetics, growth performance, carcass traits and fatty acid profile in meat of finishing lambs

To determine the effect of adding β2 agonist zilpaterol hydrochloride during different periods on growth performance, dietary energetic, carcass traits and fatty acid profile, forty male lambs Pelibuey × Katahdin (37.70 ± 0.83 kg) were blocked by body weight and randomly assigned to pens. Treatments consisted in: 1) control, no zilpaterol supplementation, 2) zilpaterol supplementation for 20 d (ZIL20), 3) zilpaterol supplementation for 30 d (ZIL30), and 4) zilpaterol supplementation for 40 d (ZIL40). Compared with control treatment, zilpaterol supplementation increased final live weight (FLW) (3.5 %; P = 0.0563), average daily gain (ADG, 14.8 %; P = 0.0598) and gain:feed ratio (10.3 %; P = 0.0324). As well as hot carcass weight (6.1 %; P = 0.0064), dress out percentage (2.6 %; P = 0.0139) and Longissimus dorsi muscle area (13.7 %; P = 0.0015). Compared to control group, zilpaterol increased (P = 0.0413) observed vs. expected dietary of NEm (net energy requirements for maintenance) and NEg (net energy requirements for growth) (5.7 and 8.1 %, respectively). Twenty days of zilpaterol treatment improved FLW (4.4 %, P = 0.0566) and tended to improve ADG (17.4 %, P = 0.0718) when compared to control group. Only intramuscular fat showed a positive linear effect (P = 0.0006) in stearic fatty acids proportion and negative linear effect (P = 0.0585) in araquidonic fatty acid proportion. We conclude that zilpaterol hydrochloride improved variables of growth performance, energy retention and carcass traits with noticeable effects from 20 d of zilpaterol supplementation.

Wildlife mortality risk posed by high and low traffic roads.

Wildlife mortality due to collisions with vehicles (roadkill) is one of the predominant negative effects exerted by roads on many wildlife species. Reducing roadkill is therefore a major component of wildlife conservation. Roadkill is affected by various factors, including road attributes and traffic volume. It is theorized that the effect of traffic volume on roadkill probability should be unimodal. However, empirical evidence for this theory is lacking. Using a large-scale roadkill database of 18 wildlife species in Israel, encompassing 2846km of roads over 10years, we explored the effects of traffic volume and road attributes (e.g., road lighting, verge vegetation) on roadkill probability with a multivariate generalized linear mixed model. A unimodal effect of traffic volume was identified for the striped hyena (Hyaena hyaena), whereas 5 species demonstrated a novel quadratic U-shaped effect (e.g., golden jackal [Canis aureus]). Four species showed a negative linear effect (e.g., wild boar [Sus scrofa]). We also identified varying effects of road attributes on roadkill. For instance, road lighting and roadside trees decreased roadkill for several species, whereas bus stops and concrete guardrails led to increased roadkill. The theorized unimodal effect of traffic volume may only apply to large, agile species, and the U-shaped effect could be related to intraspecies variability in traffic avoidance behavior. In general, we found that both high-traffic and low-traffic roads can pose a high mortality risk for wildlife. It is therefore important to monitor roadkill on low-traffic roads and adapt road attributes to mitigate roadkill. Road design for effective roadkill mitigation includes reducing the use of concrete guardrails and median barriers where possible and avoiding dense bushes in verge landscaping. These measures are complemented by employing wildlife detection systems, driver warnings, and seasonal speed reduction measures on low-traffic roads identified as roadkill hotspots.

Racial disparities in law enforcement/court-ordered psychiatric inpatient admissions after the 2008 recession: a test of the frustration–aggression–displacement hypothesis

BackgroundSocieties under duress may selectively increase the reporting of disordered persons from vulnerable communities to law enforcement. Mentally ill African American males reportedly are perceived as more threatening relative to females and other race/ethnicities. We examine whether law enforcement/court order-requested involuntary psychiatric hospitalizations increased among African American males shortly after ambient economic decline—a widely characterized population stressor.MethodsWe identified psychiatric inpatient admissions requested by law enforcement/court orders from 2006 to 2011 across four US states (Arizona, California, New York, North Carolina). Our analytic sample comprises 13.1 million psychiatric inpatient admissions across 95 counties over 72 months. We operationalized exposure to economic downturns as percent change in monthly employment in a metropolitan statistical area (MSA). We used zero inflated negative binomial and linear fixed effects regression analyses to examine psychiatric inpatient admissions requested by law enforcement/court orders following regional employment decline over a time period that includes the Great Recession of 2008.Findings.Declines in monthly employment precede by one month a 6% increase in psychiatric hospitalizations requested by law enforcement/court order among African American males (p < 0.05), but not among other race/sex groups. Estimates amount to an excess of 2554 involuntary admissions among African American males statistically attributable to aggregate-level employment decline.ConclusionsEconomic downturns may increase involuntary psychiatric commitments among African American males. Our findings underscore the unique vulnerability of racial/ethnic minorities during economic contractions.

Opportunity for a Healthy Campus Program as a Sustainable Development Goal: Assessing Lifestyle Factor and Mental Health Status

Background: Globally, mental health has become a major issue in health development today. Campus communities cannot be separated from the problem of mental health. Aims: This study aims to describe the relationship between demographic and lifestyle factors with mental health status in campus communities. Method: This study used a quantitative method with a cross-sectional design. Data collection was conducted through an online survey on 11-30 October 2021 at one of the universities in Yogyakarta. There were 503 respondents consisting of students, lecturers, and education staff. The instrument of mental health was the Self-Reporting Questionnaire-29 (SRQ-29). Result: There were indications of needing referral due to anxiety and depression as much as 33.4%, and there were 5.28% of respondents requiring referral due to psychotic disorders, drugs, and PTSD. Demographic factors associated with mental health status were job status, sex, and age. Meanwhile, lifestyle aspects that are associated with mental health status are physical activity duration and fruit and vegetable consumption per day. This was indicated by the respective p-values of 0.000 (job status), 0.042 (sex), 0.027 (age), 0.003 (duration of physical activity), and 0.011 (consumption of fruits and vegetables per day). Furthermore, multivariate analysis showed that the duration of physical activity, as well as fruit and vegetable consumption, had a negative linear effect on the incidence of mental health disorders. Conclusion: The main findings provide baseline data for developing healthy campuses as part of sustainable development goals (SDGs), particularly for mental health programs.

Hungry herbivores and thirsty plants: Browsing wildlife shape savanna tree transpiration independently of water use strategies

Abstract Plant transpiration is a key component of the hydrological cycle that moves water from the soil through plants to the atmosphere and is largely determined by environmental conditions. The challenges of highly variable climatic conditions and water scarcity in the semi‐arid savannas of southern Africa drive trees to exhibit different water use strategies. An additional challenge for savanna trees arises from the browsing of large mammals, and its potential impact on transpiration has largely been overlooked. To assess water use strategies and the impact of browsing on transpiration in three common savanna woody species (Colophospermum mopane, Catophractes alexandri, Senegalia mellifera), we conducted an extensive field experiment in a wildlife reserve in Namibia. We established a browsing gradient ranging from 0% to 100% leaf removal to disentangle complex relationships, and we measured sap flow representing whole‐tree transpiration, stomatal conductance as a proxy for leaf level transpiration, and environmental factors including soil moisture, solar radiation, air temperature and air humidity. We discovered a unimodal relationship between browsing intensity and sap flow, consistent across all species, and peaking at low to moderate browsing levels equivalent to approximately 30% leaf removal. This universal pattern is remarkable since we found water use strategies to differ among species: Colophospermum mopane and C. alexandri exhibit a water‐saving behaviour to reduce water loss under unfavourable conditions while S. mellifera demonstrates water‐spending characteristics. The deviation from a negative linear effect of browsing does not meet the functional expectation when browsing is translated into a simple leaf area reduction. Instead, it can be attributed to stomatal adjustments that partially compensate for transpiratory surface loss. We propose that this conceptual mechanism can be generalised to other woody species and various ecosystems. In addition, common transpiration models relying solely on leaf area indices and abiotic factors can be improved by including a non‐linear relationship to reproduce the effect of browsing accurately. Our findings highlight the role of herbivores in shaping the connection between the Earth's spheres and improve our understanding of ecohydrological and vegetation dynamics in Southern African savannas.

Effects of the replacement corn meal by whole mango meal on tambaqui (Colossoma macropomum) diet: Digestibility, growth performance, biochemical, and hematological responses.

This study evaluated the digestibility of whole mango (Mangifera indica) meal (WMM) and determined the growth performance, intestinal enzyme activity, and metabolic and hematologic responses of tambaqui (Colossoma macropomum) juveniles fed diets containing different proportions of corn meal (CM) substitution by WMM. Fish fed with graded levels of WMM (0 (control), 80, 160, 240, and 320 g kg diet-1), replacing part of the dietary CM. The apparent digestibility coefficients of WMM were above 96%. Diets with WMM did not affect growth performance or intestinal enzyme activity. However, they showed a positive linear effect on plasma glucose, amino acids, and albumin levels and a negative linear effect on hepatic aspartate aminotransferase activity and hepatic glycogen, plasma cholesterol, and hemoglobin levels. Increased erythrocyte values and decreased plasma triglyceride levels were verified in fish fed 80 and 160 g WMM kg diet-1. In conclusion, the WMM may be a viable alternative to the tambaqui juveniles' diet, and WMM could replace up to 16% of CM without harming the growth and health of tambaqui juveniles.

Self-Reliance in the Workplace: The Curvilinear Effect of Workplace Ostracism on Subjective Career Success

Workplace ostracism, which is defined as the extent to which an individual perceives that he or she is ignored or excluded by others, has become a pervasive phenomenon. Most scholars found that workplace ostracism has a negative linear effect on the employees’ work outcomes. However, based on the transactional theory of stress and coping, individuals could evaluate pressure and take action to solve the problems. Thus, they could positively cope with workplace ostracism when they are in trouble. This study investigates the curvilinear relationship between workplace ostracism, psychological empowerment, and the employees’ career success using a multi-wave design (257 respondents from three-time points). We found the curvilinear effect of workplace ostracism on subjective career success via psychological empowerment. The current investigation supports the theorized links and offers notable implications for personnel assessment and career development.

The effect of varying levels of corticated marama bean (Tylosema esculentum) meal on growth performance, apparent retention of feed components, and physiological and meat quality parameters in Jumbo quail

This study evaluated the effect of varying levels of corticated marama bean (Tylosema esculentum) meal (CMBM) on growth performance, apparent retention (AR) of feed components, and physiological and meat quality responses in Jumbo quail. Five isocaloric and isoproteic diets were formulated to contain 0 (T1), 51.25 (T2), 67.49 (T3), 83.74 (T4), and 99.98 g/kg (T5) of CMBM. A total of 385, one-week-old quail chicks (26.7 ± 2.16 g live-weight) were placed in cages (11 birds/cage) based on body weight. The diets were allocated to cages in a completely randomised design to give 7 replicate cages per diet. Feed intake (FI), body weight gain (BWG), gain-to-feed ratio (G:F), as well as AR of feed components were measured. The birds were slaughtered at day 35 for measurements of blood indices, organs weight, carcass and meat quality attributes. Feeding increasing levels of CMBM reduced FI (P = 0.005) linearly in week 2 but had no effect on FI in weeks 3–5. Similarly, linear reductions (P < 0.0001) were observed for average weekly BWG and G:F in weeks 2 and 3. A positive linear effect (P = 0.033) and a negative cubic effect (P = 0.048) for AR of neutral detergent fibre and organic matter were recorded as CMBM levels increased, respectively. However, varying responses (P < 0.05) were observed for AR of essential amino acids (methionine, lysine, threonine, etc.). Serum lipase, neutrophils, eosinophils, monocytes, and basophils linearly increased (P < 0.05) with dietary CMBM levels. Significant cubic or quartic effects (P < 0.05) were recorded for serum glucose, albumin, white blood cells, neutrophils, monocytes, basophils, and platelets. There were negative linear effects (P < 0.05) for final body weight, carcass yield, and breast meat drip loss. However, linear increases were recorded for gizzard, proventriculus, small intestine, and large intestine weights as dietary CMBM levels increased. In conclusion, the inclusion of CMBM up to 99.98 g/kg in Jumbo quail diets compromised growth performance, physiological responses, slaughter weights and carcass yield of Jumbo quail.

Effect of feeding semi-moist diet as a practical strategy to reduce feed costs in tilapia juvenile production

Tilapia (Oreochromis niloticus) is one of the species with the greatest increase in production worldwide. However, the continuous increase in the price of ingredients, and consequently in the diet costs may limit the expansion of the sector. Several alternatives to reduce feed costs are currently under study, as the use of practical press-pellet semi-moist diet that can be manufactured on farm. This study evaluates five levels of replacement (0, 25, 50, 75, and 100%) of a commercial diet by a practical (press-pellet semi-moist) diet and its effect on zootechnical performance, carcass proximate composition, as well as somatic and economic indexes in tilapia juveniles (9.48 g). After 56 days, survival and condition factor did not differ significantly between treatments. Final weight, daily weight gain, feed conversion, and specific growth rate had a negative linear effect as the practical diet increased, while carcass yield had a positive linear effect. Carcass crude protein content was higher in fish fed with 100% practical diet, while crude lipid had the lowest content in this same treatment. As for economic indexes, the estimated cost of feeding decreased as a function of the practical diet inclusion, with a final saving of US$ 8.68 per thousand of juveniles produced (100% replacement).

The Sustainability of Emotional Intelligence and Decision-Making Flair by Financial Investors Through the Mediating Role of Coachability

Abstract Research background Investors today are more inclined towards a financial market that increases their knowledge and excess involvement. It is often observed that they are extensively emotionally involved, that impact financial investors’ investment decisions. It is observed that investors always seek guidance from an expert to invest in more appropriate products and services. This guidance and support lead to reaching the ultimate satisfaction of the participants. Purpose: This paper aims to examine the potential mediating role of investor coachability and its impact on financial investors’ emotional intelligence and decision-making styles. Research methodology The structured questionnaire was circulated among 106 respondents, of which 102 useful responses were considered. This research used validated scales of the Coachability Quotient questionnaire and the Schutte Self-Report Emotional Intelligence Test (SSEIT). The study has applied multiple regressions to predict rational decision-making and intuitive decision-making style through emotional intelligence and coachability as mediators. Results The results have found that emotional intelligence has a significant positive linear effect on coachability, with a positive direct impact on intuitive decision-making style. It was also found that emotional intelligence was found to have a significant positive direct effect on intuitive decision-making style and a negative linear direct effect on avoidance decision-making style. Novelty This research was to introduce the idea of incorporating behavioural finance or financial coaching as standard practice and to help investors learn to cope with the ever-increasing demands of the financial markets.
