Role of medicinal mushroom on growth performance and physiological responses in broiler chicken

SUMMARY Supplementing broiler diets with medicinal mushrooms is considered an effective alternative to prophylactic antibiotics. Feeding certain mushrooms may have beneficial effects on gut health in broilers, whereby trials have shown weight gain was increased about 5.2% when feeding 5% of the Hericium caput-medusae mushrooms in the diet. Both Salmonella spp. and E. coli numbers in the caecum were significantly lowered from 5.036 to 3.031 log10 CFU/g and from 5.405 to 4.759 log10 CFU/g when 50 g/kg or 30 g/kg of Flammulina velutipes mushrooms were included in feed, respectively, compared to an unsupplemented control group. Beneficial bacteria (Lactobacilli spp.) were found in significantly higher numbers (increased from 6.45 to 8.05 log10 CFU/g) and Bifidobacter spp. (increased from 6.28 to 7.77 log10 CFU/g of content) in the caecum of broilers fed 20 g/kg mushrooms (Agaricus biosporus) in feed. However, there is still disagreement in published articles on the dosages and mode of action of medicinal mushrooms in broilers. The following review covered the published trials investigating the uses of medicinal fungi on growth performance, meat quality and health status in broiler to date, and showed that supplementation with medicinal fungi may have a role on the immunity, health and growth performance in broiler.
Whither guanxi and social networks in China? A review of theory and practice

ABSTRACT The analysis of guanxi and social networks is well-established but heated debates continue on its utility in Chinese business and management. Many argue that it offers an emotionally sensitive, network-based form of resource allocation, uniquely fitted to China’s distinctive national culture. Others assert that it impedes open-market competition and merit-based reward, factors assumed to be essential for the optimal functioning of capitalist economies. Our collection of research offers new empirical insights and nuanced conceptual development on these debates, demonstrating the continuing relevance of guanxi in the 21st century. This is achieved through examining multinational enterprise corporate performance, governance structures in Chinese private firms, organizational justice in Chinese banks, entrepreneurial learning and knowledge acquisition and the gendered nature of guanxi in the workplace. Important theoretical and practical implications from these studies are highlighted, as well as the key implications for future research. The collection is dedicated to the memory of our dear friend, mentor and colleague, Professor Malcolm Warner, who passed away during its development.
Intellectual capital management within the framework of the VBM concept

Currently, the process of forming new management concepts is ongoing in Russia. At the same time, on the way to the development, creation and implementation of modern concepts, approaches and management systems at domestic enterprises there are several problems, one of which is the problem of intellectual capital management based on the VBM concept. Issues related to the definition of the concept of “intellectual capital”, its assessment and management are relevant. The article discusses the features of the VBM concept at the enterprise level, its advantages and disadvantages, implementation problems. The analysis performed in the study made it possible to clarify the economic content of the concept of intellectual capital and identify its key features that allow characterizing it and using specific assessment methods. The article describes the main methods and indicators for assessing intellectual capital, based on which an approach to the assessment and management of intellectual capital of an enterprise is proposed. The approach is based on a combination of two methods for calculating intellectual capital CIV and MVAIC. The first technique allows to assess the amount of intellectual capital of the enterprise. The second technique allows to reveal the structure of intellectual capital. The joint use of techniques allows to get a valuation of the intellectual capital of the enterprise and evaluate the effectiveness of investments in the development of its components. Criteria for assessing the effectiveness of investments in elements of intellectual capital are proposed.
Exchanging fluidsThe sociocultural implications of microbial, cultural, and ethnic admixture in Latin America

Abstract. Knowledge of evolutionary influences on patterns of human mating, social interactions, and differential health is increasing, yet these insights have rarely been applied to historical analyses of human population dynamics. The genetic and evolutionary forces behind biases in interethnic mating and in the health of individuals of different ethnic groups in Latin America and the Caribbean since the European colonization of America are still largely ignored. We discuss how historical and contemporary sociocultural interactions and practices are strongly influenced by population-level evolutionary forces. Specifically, we discuss the historical implications of functional (de facto) polygyny, sex-biased admixture, and assortative mating in Latin America. We propose that these three evolutionary mechanisms influenced mating patterns, shaping the genetic and cultural landscape across Latin America and the Caribbean. Further, we discuss how genetic differences between the original populations that migrated at different times into Latin America contributed to their accommodation to and survival in the different local ecologies and interethnic interactions. Relevant medical and social implications follow from the genetic and cultural changes reviewed.
A Dual-mode Communication Power Internet of Things Routing Algorithm Based on RPL Protocol

Medium frequency (less than 12 MHz) Power Line Communication (PLC) and micro-power wireless Radio Frequency (RF) communication dual-mode communication technology can realize the depth and breadth coverage of the power Internet of Things (IoT) and enhance the robustness of the network. But dual-mode communication also brings difficulties to the application of the RPL protocol. According to the characteristics of PLC and RF dual-mode communication technology, the routing communication delay is the optimization objective function, and a routing metric algorithm of RPL routing protocol is proposed. The RPL protocol is applied to the dual-mode communication in power Internet of Things. Experiments show that the proposed algorithm has higher communication efficiency and can meet the needs of dual-mode communication hybrid networking and operation. It is a feasible method.
Silk fibroin/hydroxyapatite scaffold: a highly compatible material for bone regeneration

ABSTRACT In recent years remarkable efforts have been made to produce artificial bone through tissue engineering techniques. Silk fibroin (SF) and hydroxyapatite (HA) have been used in bone tissue regeneration as biomaterials due to mechanical properties of SF and biocompatibility of HA. There has been growing interest in developing SF/HA composites to reduce bone defects. In this regard, several attempts have been made to study the biocompatibility and osteoconductive properties of this material. This article overviews the recent advance from last few decades in terms of the preparative methods and application of SF/HA in bone regeneration. Its first part is related to SF that presents the most common sources, preparation methods and comparison of SF with other biomaterials. The second part illustrates the importance of HA by providing information about its production and properties. The third part presents comparative studies of SF/HA composites with different concentrations of HA along with methods of preparation of composites and their applications. Graphical abstract
An examination of the relationship between hotel employees’ use of upward influence tactics and supervisor rating of employee promotability

Abstract This study investigated how employees’ use of upward influence tactics predicted supervisor assessment of employee promotability. Data were collected from a four-star hotel in The Netherlands. One hundred and two employees’ use of upward influence tactics and their promotability were rated by their immediate supervisors. The findings showed that exchange positively and ingratiation negatively predicted promotability. Moreover, hard tactics interacted with rational tactics in predicting promotability. Specifically, assertiveness was positively related to promotability when rationality was high and unrelated to promotability when rationality was low; coalition was positively related to promotability when rationality was high and negatively related to promotability when rationality was low; coalition was positively related to promotability when exchange was high and unrelated to promotability when exchange was low; and upward appeal was negatively related to promotability when rationality was low and unrelated to promotability when rationality was high. Theoretical and practical implications were discussed.
Intrinsically Distributed Probabilistic Algorithm for Human–Robot Distance Computation in Collision Avoidance Strategies

Humans and robots are becoming co-workers, both in industrial and medical applications. This new paradigm raises problems related to human safety. To accomplish and solve this issue, many researchers have developed collision avoidance strategies—mainly relying on potential field approaches—in which attractive and repulsive virtual forces are generated between manipulators and objects within a collaborative workspace. The magnitude of such virtual forces strongly depends on the relative distance between the manipulators and the approaching agents, as well on their relative velocity. In this paper, authors developed an intrinsically distributed probabilistic algorithm to compute distances between the manipulator surfaces and humans, allowing tuning the computational time versus estimation accuracy, based on the application requirements. At each iteration, the algorithm computes the human–robot distances, considering all the Cartesian points within a specific geometrical domain, built around humans’ kinematic chain, and selecting a random subset of points outside of it. Experimental validation was performed in a dynamic and unstructured condition to assess the performance of the algorithm, simulating up to six humans into the shared workspace. Tests showed that the algorithm, with the selected hardware, is able to estimate the distance between the human and the manipulator with a RMSE of 5.93 mm (maximum error of 34.86 mm).
Modified Nucleosides Always Were: an Evolutionary Model

This chapter evaluates the distribution of modified nucleosides in certain RNA species of the three domains of life (archaea, bacteria, and eukaryotes). Fourteen modifications are present in all three domains and of these several are found at comparable positions in tRNAs . First, most of the conserved modified nucleosides are in or near the anticodon loop. There is strong phylogenetic evidence for the early appearance of modified nucleosides. The incorporation of modified nucleosides into nucleic acid polymers is quite plausible, and the use of a particular nucleoside may depend only on its concentration in the primordial soup. Again, considering the chemistry of nucleosides, it would seem that the moderately modified nucleosides would be present in the highest concentrations in the primordial soup along with the standard nucleosides. In parallel, the phylogenetic evidence suggests that some simple modified nucleosides existed at the point when the major organismal groups diverged. In the case of tRNAs, there is no evidence for present-day RNA guiding, although such a system could be imagined early in the evolution of replicating cells. The current evidence of the enzymes involved in RNA-guided modification leaves the door open to speculation that RNA has a greater role in this process than simply guiding modification.
The stories that make us: Leaders’ origin stories and temporal identity work

The stories we tell about our origins can shape how we think and act – helping us make sense of and communicate who we have “become” over time. To better understand the role that origin stories play in individuals’ work lives, we explore how 92 men and women leaders make sense of “becoming” a leader (origin stories) and “doing” leadership (enactment stories). We find that, despite the uniqueness of their experiences, their narratives converge around four frames, being, engaging, performing, and accepting, through which they understand, articulate, and enact their leader identities. We theorize that these narrative frames serve as sensemaking and identity work devices which allow them to create temporal coherence, validate their leader identity claims, and offer them behavioral scripts. Our findings also unearth key gender differences in the use of these frames, in that men used the performing frame more often and women tended toward the engaging frame. These findings provide novel insights into the ways in which the gendered context of leadership becomes embedded in leaders’ understandings of who they are and what they intend to do in their roles. We discuss the theoretical implications of our findings on scholarly conversations around identity, leadership, and gender.
Large-eddy simulation and modelling of Taylor–Couette flow

Wall-resolved large-eddy simulations (LES) of the incompressible Navier–Stokes equations together with empirical modelling for turbulent Taylor–Couette (TC) flow are presented. LES were performed with the inner cylinder rotating at angular velocity $\unicode[STIX]{x1D6FA}_{i}$ and the outer cylinder stationary. With $R_{i},R_{o}$ the inner and outer radii respectively, the radius ratio is $\unicode[STIX]{x1D702}=0.909$. The subgrid-scale stresses are represented using the stretched-vortex subgrid-scale model while the flow is resolved close to the wall. LES is implemented in the range $Re_{i}=10^{5}{-}10^{6}$ where $Re_{i}=\unicode[STIX]{x1D6FA}_{i}R_{i}d/\unicode[STIX]{x1D708}$ and $d=R_{o}-R_{i}$ is the cylinder gap. It is shown that the LES can capture the salient features of the flow, including the quantitative behaviour of spanwise Taylor rolls, the log variation in the inner-cylinder mean-velocity profile and the angular momentum redistribution due to the presence of Taylor rolls. A simple empirical model is developed for the turbulent, TC flow for both a stationary outer cylinder and also for co-rotating cylinders. This consists of near-wall, log-like turbulent wall layers separated by an annulus of constant angular momentum. Model results include the Nusselt number $Nu$ (torque required to maintain the flow) and measures of the wall-layer thickness as functions of both the Taylor number $Ta$ and $\unicode[STIX]{x1D702}$. These are compared with results from measurement, direct numerical simulation and the LES. A model extension to rough-wall turbulent flow is described. This shows an asymptotic, fully rough-wall state where the torque is independent of $Re_{i}/Ta$, and where $Nu\sim Ta^{1/2}$.
Bighorn sheep diet selection and forage quality in central Idaho.

Rocky mountain bighorn sheep (Ovis canadensis canadensis) populations in the Big Creek drainage of central Idaho spend the winter on low elevation, southern exposures where snow depths are reduced or absent. Approximately 50% of the population migrates to higher elevations during warmer months, thus potentially extending the period of spring green-up and its accompanying higher levels of forage nutrient content and digestibility. Other bighorns remain on low elevation winter range year-round, experiencing warm, dry conditions and lower forage nutrient values earlier than sheep migrating to higher elevations. The objective of this study was to determine and interpret the seasonal diet selection of the non-migratory portion of the population. Microhistological analysis of composite fecal samples was used to determine diet composition, and plant samples were analyzed for crude protein, digestibility, and macro and micro nutrients to examine forage quality. Graminoids made up the majority of the diet throughout the year. During spring green-up when protein content and digestibility of grasses were at peak levels, consumption of forbs and browse declined. However, forbs and browse provided important sources of nutrients, especially protein, at critical times of the year when grasses were low in nutritional value and digestibility. Non-migratory bighorns had developed flexible and dynamic feeding behaviors that allowed them to meet their nutritional needs while remaining in a relatively warm, dry environment. Managers should focus on providing a diversity of plant species in all forage categories. Invasions of exotic plant species that reduce biodiversity may negatively impact bighorn sheep populations.

A fully probabilistic design for stochastic systems with input delay

This paper is concerned with the regulation problem of discrete-time stochastic systems involving input delays which is relevant to networked control systems. The problem is formulated in a fully probabilistic framework, and the control solution is obtained by minimising the Kullback–Leibler Divergence (KLD) between the actual and desired joint probability density functions of the system dynamics. A closed-form solution for the randomised controller is obtained for stochastic systems that can be described by arbitrary probability density functions. Furthermore, the analytic solution for a class of linear Gaussian stochastic systems is obtained. For this class of systems, the optimal randomised controller is shown to be a state feedback controller which is modified by an extra linear term that is related to the lagged and future control inputs. The developed method is demonstrated on a simulation example, and the results are compared with the standard fully probabilistic design control method.
Reliability Analysis of an Instrument: A Preliminary Study of Experience in Close Relationship Scale (ECR) among Counsellor Trainees in a University

The study aims to evaluate the reliability and internal consistency of Experience in Close Relationship among counsellor trainees in one of the local universities. The questionnaire had 36 items that were tested on 58 students from Bachelor of Counselling with Honours program. The Experience in Close Relationship Scale (ECR) is used to assess attachment styles. The ECR assesses individual on two sub-scale of attachment which are attachment avoidance and attachment anxiety. This study presented listed items and internal consistency reliability analysis of Experience in Close Relationship Scale (ECR) in Malaysian context. The explanation on the items and reliability analysis represents the appropriateness of the instrument to trainee counsellors from public universities. The two sub-scale showed high reliability analysis. The reliability values of two sub-scale are reported respectively as following (i) attachment anxiety α = . 86; and (ii) attachment avoidance α = . 93. The instrument is reliable for assessing the attachment styles towards counsellor trainees at public universities. Therefore, the results from the pilot study showed that the questionnaire can be used without any modification in the actual study.

Preliminary Data on the Effects of Econase Supplementation on Milk Yield and Behavior of Transition Cows

Funded by: The College of Food. Agricultural, and Natural Resource Sciences. The transition period of a dairy cow – from 3 weeks before calving to three weeks after – is considered one of the most important time periods relative to cow health, production, and profitability. Most infectious diseases and metabolic disorders occur during the transition period. This is due to a decrease in dry matter intake (DMI) observed in transition cows, coupled with an increase in nutrient requirements for milk production. This nutritional imbalance, alongside the stresses associated with calving, is largely responsible for the great numbers of health issues associated with transition cows, and results in decreases in milk production.1
COMPARATIVE STUDY REGARDING THE FATTY ACIDS PROFILE IN SHEEP MILK RELATED TO THE BREED AND PARITY

Our objective was to analyse milk yield, milk components, and especially fatty acid profile of ewes’ milk fat, in relation with breed, and parity. The sheep were used in a 3 x 2 factorial arrangement consisting of a combination of breeds (n = 3: Merinos of Transylvania, Tigaie and Turcana) and parity (n = 2: primipara and multiparous). Turcana ewes yielded more milk, and milk fat had a lower content of saturated FA and a higher content of polyunsaturated FA, so that the atherogenic index recorded the best value for this breed. Turcana breed also had the highest concentration of cis�9, trans�11 CLA (conjugated linoleic acid) in milk, which was due not only to an increase of C18:1 trans�11 supply in the rumen, but also to an increase in 4 9 – Desaturase enzyme activity. Milk n�3 FA content, mainly that in α – linolenic acid, was not influenced by breed, but it decreased as lactation number increased. Milk yield and its components increased with parity, while the proportion of n�3 FA and cis�9, trans�11 CLA in milk fat decreased, that is, the nutritional quality of milk decreased if we look at its influence on human health.
Detection of Bacteriophage in Droplets

Transmission of respiratory diseases, including of respiratory syncytial virus (RSV), can be via small droplets that are able to remain suspended in the air and subsequently be inhaled by a susceptible host (Centers for Disease Control, 2010). However, little information is available on the specifics of transmission via aerosol droplets. A greater understanding of the fate of viruses in droplets, and the effect of physical factors that govern aerosol spread, is needed to control the spread of viral infections. The research undertaken in this study addresses some questions surrounding aspects of virus transmission via the aerosol route, in order to contribute to a more comprehensive understanding of this issue.
