Abstract Conyza Blinii (C. blinii) is a unique traditional Chinese medicine growing in Sichuan, China, which has soils with an abundant iron content. This Fe enrichment environment contributed to a variety of terpenoids of C. blinii, blinin and saponin which can play an important role in the process of resisting abiotic stress. The relationship between Fe and terpenoid metabolism was studied to explore Fe tolerance mechanism of C. blinii. In this study, C. blinii was treated with ferrous iron solutions, and the effect of ferrous iron on the synthesis of blinin and saponins was further studied by spectrophotometry and liquid chromatography. Also, gene expression was detected by qRT-PCR. Under ferrous treatment, the blinin content of C. blinii increased, while the total saponin content decreased. When the ferrous concentration reached 200 μM, the difference in metabolite production was the largest. Furthermore, it was found that blinin and saponin have synchronous and opposite accumulation trends, accompanied by time dependence. The genes expression results of key enzyme in the MVA and MEP pathways showed the same trends. In this process, the expression of CbNudixs played a key role to switch the material flux between MVA and MEP, via catalyzed the dephosphorylation of isoprenoid diphosphate. This study explored the effect of ferrous iron on the saponin and blinin synthesis of C. blinii and found the unique role of CbNudixs in regulating material flux between diterpene and triterpene synthesis, which greatly deepened our understanding of the mechanism of Fe tolerance of C. blinii.

The purpose of the study is to investigate the relationship between locus of control and impression management. The study also examines the variation in locus of control dimensions namely, internality, externality (others) and externality (chance). It further investigates the difference on perception of demographic variables (gender and marital status) and sectoral difference on impression management. The study was administered on 125 Managers who were representatives of different private and public sector organizations in Delhi/NCR. Variables in the study were assessed using validated instruments. Descriptive Statistics, t-test, Correlation and Regression were used for data analysis. Organizations will be better prepared to dig into the arena of one of the personality variable, i.e. locus of control and its relationship with impression management. The current research is imperative in providing insights into role of personality variable (locus of control) and impression management, which will be one of the pioneer researches available till date. Moreover, the research will highlight the significance of locus of control dimensions and impression management.

In this paper we argue that to understand the difference Posthumanism makes to the relationship between archaeology, agency and ontology, several misconceptions need to be corrected. First, we emphasize that Posthumanism is multiple, with different elements, meaning any critique needs to be carefully targeted. The approach we advocate is a specifically Deleuzian and explicitly feminist approach to Posthumanism. Second, we examine the status of agency within Posthumanism and suggest that we may be better off thinking about affect. Third, we explore how the approach we advocate treats difference in new ways, not as a question of lack, or as difference ‘from’, but rather as a productive force in the world. Finally, we explore how Posthumanism allows us to re-position the role of the human in archaeology,

The urban fabric of the desert cities is based on the principle of reducing the impact of urban canyons on direct solar radiation. Here comes this research, which is based on a comparative study of the periods of direct solarisation and values of the solar energy of urban canyons via two urban fabrics that have different building densities, where the ratio between L/W is different. In order to obtain the real values of the solar energy (thermal, lighting), the test field was examined every two hours, each three consecutive days. The measurement stations are positioned by the three types of the relationship between L/W, (L≥2w, L=w, L≤0.5w). According to the results, we noticed and recorded the difference in the periods of direct solarization between the types of urban engineering canyons, reaching 6 hours a day, the difference in thermal values of air, reaching 4 °C, and the difference in periods of direct natural lighting, reaching 6 hours. It should be noted that the role of the relationship between L/W is to protect the urban canyons by reducing the impact of direct solar radiation on urban canyons, providing longer hours of shading, and reducing solar energy levels (thermal, lighting) at the urban canyons. This research is classified under the research axis (the studies of external spaces in the urban environment according to the bioclimatic approach and geographic approach). But this research aims to focus on the tracking and studying the distribution of the solar radiation - thermal radiation and lighting radiation - in different types of street canyons by comparing the study of the direct solarization periods of each type and the quantity of solar energy collected during the solarization periods.

This study examined the relationship between audit delay after IFRS adoption and the role of shareholders in the audit committee as well as testing the difference of pre-and post IFRS adoption periods. A sample of 101 firms with 505 firm-year observations over five year period for firms listed on the Nigeria Stock Exchange was employed for the study, utilizing data from the annual report and accounts of the sample firms. Generalized Methods of Moment (GMM) estimation was used to check the effects of unobserved heterogeneity in audit delay model, while the test of difference in R2 value for pre-and post-adoption periods was determined using Cramer’s Z-statistics. Findings indicate that audit report lag is faster with shareholders in the audit committee. The study proved that brand named auditors such as Big4 can significantly perform faster audit task than non-Big4 firms in IFRS regime. The importance of the study’s findings demonstrates statistical inference on value relevance increase based on the unique IFRS adoption in Nigeria. Thus, regulators should consider increasing the tenure of shareholders in the audit committee to enable them to become more familiar with the corporate reporting under IFRS regime.

The Relationship

Russia's Armenians have begun to form diaspora institutions and engage in philanthropy and community organization, much as the pre-Soviet “established” diaspora in the West has done for years. However, the Russian Armenian diaspora is seen by Armenian elites as being far less threatening due to a shared “mentality.” While rejecting the mentality argument, I suggest that the relationship hinges on their shared political culture and the use of symbols inherited from the Soviet Union in the crafting of new diaspora and diaspora-management institutions. Specifically, “Friendship of the Peoples” symbolism appears to be especially salient on both sides. However, the difference between old and new diasporas may be more apparent than real. The Russian Armenian diaspora now engages in many of the same activities as the Western diaspora, including the one most troublesome to Armenia's elites: involvement in politics.

This chapter examines the role of interest groups in European Union (EU) politics. It also considers the way in which the EU institutions influence interest group structures and activities. The chapter begins with an overview of the relationship between the EU institutions and interest groups and examines the steps taken thus far to regulate that relationship. It then looks at the evolution and the structure of the interest group system, focusing in particular on two salient aspects: the difference between national and EU organizations; and the difference between specific and diffuse interests.

Purpose This study aims to explore the factors moderating possibly indirect relationships between gender diversity and its effect on bank performance. The causality of this relationship remains unclear. Design/methodology/approach The sample consists of all banks (n = 27) operating in Serbia. Findings The gender diversity-performance relationship is indirect. The gender diversity of executive boards positively impacts bank performance, over a threshold level. This is observed only in banks where gender diversity is extended to more than one level of executive authority. Research limitations/implications Gender diversity should be fostered, particularly in small and competitive markets. The gender diversity-performance link is based on gender-related social interactions, which are interdependent and should not be taken into account as isolated factors. Originality/value To the knowledge, this is the first study to provide insight into indirect, gender related, moderatory interactions effecting gender diversity – performance link, in banking.

Insight Into

Public Relations (PR) in Latvia is a new cross - disciplinary branch, the beginning of which dates back to the gaining of independence. It has rapidly developed during the last twenty years. The interpretation of Public Relations though is still problematic. A lot of heads of establishments do not realize the importance of Public Relations in the development of enterprises. They do not see the difference between Public Relations and marketing. Public Relations is often viewed as a marketing supporting function. The aim of the article is to show the role of Public Relations as one of the essential management functions, explain and analyse the relationship between Public Relations and marketing, as well as to find the reason for the scarcity of the insight into what Public Relations is and offer the solution to the problem in regard to the situation in Latvia. The article offers analysis of the facts obtained from 25 detailed interviews with leading Public Relations practitioners and theoreticians as well as the analysis of the theoretical literature and other sources. All interviews could not be viewed in the article because of its limited length.

The Relationship

We present a rationale and proposed approach to the modification and development of bind sites using their respective cognate ligands as template. This is in support of a plausible “instructive” role for the ligand and therefore its involvement in determination of the structure and properties of bind sites. We emphasize the relationship between substrate and active site as an example of the relationship between ligand and bind sites, respectively. This is based on the assumption that there are shared features between all ligand:bind site complexes. Therefore, principles that apply to a specific complex can be applied, in general, to other protein-based complexes. We define ligand-associated probability bias as the difference between the probability of finding activity-determining conformations (ADCs) in the presence- and absence of ligands. For cognate ligands, the given bias is in favor of these ADCs. Thus, bind sites are more likely to assume ADCs when their cognate ligands are present. We relate such probability bias to structural reorganization, disorganization, and preorganization events. We then propose a means of deriving an [apparent] preorganized bind site structure by way of reorganization events that occur with cognate ligand. Finally, we propose a means of deriving an [actual] preorganized bind site structure by way of reorganization events that occur with cognate ligand, albeit during the folding process. The assumption is that the role of the ligand in derivation of such [actual] preorganized bind site structures is an instructive role, and is in support of the Haurowitz-Pauling hypothesis.
